In the changing market environment of livestock products, the delivery of animal health services is emerging as an important priority area for enhancing the competitiveness of poor livestock producers. At the same time, governments are continuing to face serious budgetary difficulties and are finding it difficult to expand the reach of these services or improve service quality. In this context of a changing environment and dwindling public resources, this paper revisits the economic framework that has thus far guided thinking about public and private sector roles in the provision of animal health services and examines the ongoing debate on livestock service delivery for the poor. The paper highlights the importance of strong institutions and appropriate legislation for regulating behaviour and enforcing contracts and re-emphasises the idea, which is supported by economic theory, that there is a need for task sharing between the public and private sectors. The paper further emphasizes the need for: a) integrating the debate on livestock service delivery with the larger debate on political economy and institutional development, and b) ensuring service access in poor marginal areas by working through membership organisations, self-help groups and civil society organisations, and by promoting the use of para-professionals and community-based animal health delivery systems.

Spatio-temporal data on human population and its driving factors is critical to understanding and responding to population problems. Unfortunately, such spatio-temporal data on a large scale and over the long term are often difficult to obtain. Here, we present a dataset on Chinese population distribution and its driving factors over a remarkably long period, from 1949 to 2013. Driving factors of population distribution were selected according to the push-pull migration laws, which were summarized into four categories: natural environment, natural resources, economic factors and social factors. Natural environment and natural resources indicators were calculated using Geographic Information System (GIS) and Remote Sensing (RS) techniques, whereas economic and social factors from 1949 to 2013 were collected from the China Statistical Yearbook and China Compendium of Statistics from 1949 to 2008. All of the data were quality controlled and unified into an identical dataset with the same spatial scope and time period. The dataset is expected to be useful for understanding how population responds to and impacts environmental change.

The population, environment, and health nexus: an Arab world perspective.

Kulczycki, A; Saxena, P C

1998-01-01

This report describes models of the links between population growth, environmental degradation, and health in Arab countries and in the world; management of the commons; urbanization and water as critical issues; and challenges in Lebanon. It is concluded that the complexity of interrelationships is difficult to untangle. Researchers frequently neglect health issues in modeling the relationships. The lack of attention to the health, development, and environment nexus has serious implications in the Middle East and North Africa. In Lebanon, national strategies do not include a national waste management strategy based on reduction, reuse, and recycling. Most Arab countries face the major issue of the lack of adequate planning in many economic sectors, which results in imbalances in supply and demand. Most Arab countries do not have adequate statistical databases upon which to base development, planning, and policy-making. The last census in Lebanon was in 1932. Information is missing on health. Health economics are ignored. It is not possible to estimate the health costs due to deficiencies in sanitation, hygiene, water, and air quality. Capacity building for environmental management and intersectoral collaboration is hampered. Arab countries with large oil reserves have ignored the population and environment links. Poorer countries will suffer the most from limited renewable water resources and their decline due to population growth. The political agenda in Arab countries should give priority to health, environment, development, and population issues.

Malnutrition due to lack of nutritional resources unfortunately remains an endemic which ravages Third World countries. Not only is malnutrition a result of continuous droughts and wars, but it is a reflection of the difficult economic circumstances which persist in these countries. Malnutrition should be specifically treated in each region with the least costly locally available means. The experience of the Protestant Hospital of Dabou proves that this manner of care is possible in the midst of a rural area with very limited resources. Hospital surveillance, nutritional education and a stay in the nutritional rehabilitation center offers these malnourished children a new chance to begin in life again. Unfortunately for some, the acquired benefits disappear once they have left the establishment and the child returns to the same least favorable socio-economic environment for his development.

Conceptual and practical issues associated with the design, operation, and performance of advanced systems and the impact of such systems on the human operators are reviewed. The development of highly automated systems is driven by the availability of new technology and the requirement that operators safely and economically perform more and more activities in increasingly difficult and hostile environments. It is noted that the operators workload may become a major area of concern in future design considerations. Little research was done to determine how automation and workload relate to each other, although it is assumed that the abstract, supervisory, or management roles that are performed by operators of highly automated systems will impose increased mental workload. The relationship between performance and workload is discussed in relation to highly complex and automated environments.

An economic model for passive solar designs in commercial environments

The model incorporates a life cycle costing approach that focuses on the costs of purchase, installation, maintenance, repairs, replacement, and energy. It includes a detailed analysis of tax laws affecting the use of solar energy in commercial buildings. Possible methods of treating difficult to measure benefits and costs, such as effects of the passive solar design on resale value of the building and on lighting costs, rental income from the building, and the use of commercial space, are presented. The model is illustrated in two case examples of prototypical solar design for low rise commercial buildings in an urban setting.

Experimental damage detection of wind turbine blade using thin film sensor array

Downey, Austin; Laflamme, Simon; Ubertini, Filippo; Sarkar, Partha

2017-04-01

Damage detection of wind turbine blades is difficult due to their large sizes and complex geometries. Additionally, economic restraints limit the viability of high-cost monitoring methods. While it is possible to monitor certain global signatures through modal analysis, obtaining useful measurements over a blade's surface using off-the-shelf sensing technologies is difficult and typically not economical. A solution is to deploy dedicated sensor networks fabricated from inexpensive materials and electronics. The authors have recently developed a novel large-area electronic sensor measuring strain over very large surfaces. The sensing system is analogous to a biological skin, where local strain can be monitored over a global area. In this paper, we propose the utilization of a hybrid dense sensor network of soft elastomeric capacitors to detect, localize, and quantify damage, and resistive strain gauges to augment such dense sensor network with high accuracy data at key locations. The proposed hybrid dense sensor network is installed inside a wind turbine blade model and tested in a wind tunnel to simulate an operational environment. Damage in the form of changing boundary conditions is introduced into the monitored section of the blade. Results demonstrate the ability of the hybrid dense sensor network, and associated algorithms, to detect, localize, and quantify damage.

Predicting the social consequences of orphanhood in South Africa.

PubMed

Bray, Rachel

2003-01-01

This paper examines and questions the predictions found in the academic and policy literature of social breakdown in southern Africa in the wake of anticipated high rates of orphanhood caused by the AIDS epidemic. Analysis of the logic underlying these predictions reveals four causal relationships necessary to fulfil such dramatic and apocalyptic predictions: High AIDS mortality rates will produce high numbers of orphans. These orphans will become children who do not live in appropriate social environments to equip them for adult citizenship. Poor socialisation will mean that children orphaned by AIDS will not live within society's moral codes (becoming, for example, street children or juvenile delinquents). Large numbers of such 'asocial' or 'antisocial' children will precipitate a breakdown in the social fabric. Evidence for each of these steps in the argument is scrutinised using available data from southern Africa and other regions that have moved further through the epidemic's cycle. The paper finds strong evidence for the first step, although variable definitions of 'orphan' make it difficult to draw accurate comparisons over time and space. Evidence for the second step is found to be mixed in terms of outcomes of AIDS orphanhood for child well-being. Moreover the argument takes little account of the social and economic environments onto which AIDS is mapped, including the economic fragility of households and pervading socio-cultural patterns of child-rearing. Data to substantiate the third step are anecdotal at best and no research is able to demonstrate a link between the long term effects of AIDS orphanhood and rising rates of juvenile delinquency. Arguments made towards the fourth step are shown to be based heavily on notions of the 'correct' social and physical environments for children and on unsubstantiated fears of alternatives to these. There is no evidence from countries where numbers of AIDS orphans are already high to suggest that their presence is precipitating social breakdown. The paper argues-somewhat provocatively-that such apocalyptic predictions are unfounded and ill-considered. By misrepresenting the problems faced by children and their families, attention is distracted from the multiple layers of social, economic and psychological disadvantage that affect individual children, families and communities. Consequently, insufficient consideration is given to the multi-faceted supports necessary to assist children to cope with extremely difficult circumstances brought about over the long term by the HIV/AIDS epidemic.

Predictive Modeling (PM) techniques are gaining importance in the worldwide health insurance business. Modern PM methods are used for customer relationship management, risk evaluation or medical management. This article illustrates a PM approach that enables the economic potential of (cost-) effective disease management programs (DMPs) to be fully exploited by optimized candidate selection as an example of successful data-driven business management. The approach is based on a Generalized Linear Model (GLM) that is easy to apply for health insurance companies. By means of a small portfolio from an emerging country, we show that our GLM approach is stable compared to more sophisticated regression techniques in spite of the difficult data environment. Additionally, we demonstrate for this example of a setting that our model can compete with the expensive solutions offered by professional PM vendors and outperforms non-predictive standard approaches for DMP selection commonly used in the market.

Community resilience and volcano hazard: the eruption of Tungurahua and evacuation of the faldas in Ecuador.

PubMed

Tobin, Graham A; Whiteford, Linda M

2002-03-01

Official response to explosive volcano hazards usually involves evacuation of local inhabitants to safe shelters. Enforcement is often difficult and problems can be exacerbated when major eruptions do not ensue. Families are deprived of livelihoods and pressure to return to hazardous areas builds. Concomitantly, prevailing socio-economic and political conditions limit activities and can influence vulnerability. This paper addresses these issues, examining an ongoing volcano hazard (Tungurahua) in Ecuador where contextual realities significantly constrain responses. Fieldwork involved interviewing government officials, selecting focus groups and conducting surveys of evacuees in four locations: a temporary shelter, a permanent resettlement, with returnees and with a control group. Differences in perceptions of risk and health conditions, and in the potential for economic recovery were found among groups with different evacuation experiences. The long-term goal is to develop a model of community resilience in long-term stress environments.

Selected Black-Coal Mine Waste Dumps in the Ostrava-Karviná Region: An Analysis of Their Potential Use

2017-12-01

The paper aims to analyse the options for the use of selected black-coal mine waste dump bodies in the Ostrava-Karviná Region. In the Czech Republic there are approximately 70 mine waste dumps, out of which 50 are located in the Ostrava-Karviná Coal District. The issue is highly topical, particularly in the region, because the dump bodies significantly affect the landscape character of the Ostrava-Karviná Region and pose ecological risks. In such cases, their redevelopment and land reclamation are not easy either from the environmental or economic points of view. It is clear that the redevelopment of such geological environment is difficult, and it is vital to make the right decisions as for what purposes the mine waste dumps should be used. Next, it is important to take into account all the economic and environmental aspects of the locality in question.

Housing conditions can impact on physical and mental health through 4 interrelated dimensions: 1) the home (the emotional housing conditions), 2) the physical housing conditions, and 3) the physical environment, and 4) the social (community) environment of the neighborhood where the house is located. In Spain, the use of the construction market as an engine for economic growth and the promotion of private property as the main type of housing tenure has led to the use of housing as a speculative good instead of its being considered a first-necessity good. While Spain is the Organisation for Economic Co-operation and Development (OECD) country with the largest housing stock per inhabitant, this stock is highly underutilized, thus excluding the most deprived sector of the population from access to housing. The impact of the current economic crisis on housing has mainly been due to a reduction in household income, which has increased the number of families or persons struggling to cover their housing costs or being evicted. Evidence indicates that this type of problem has a negative impact on health, especially on mental health, but financial problems also make it difficult to meet other basic needs such as eating. There are several instruments to reduce the impact of the economic crisis, such as debt financing or deed of assignment in payment. In the long-term, the creation of a social housing stock should be promoted, as well as rental assistance mechanisms. Copyright © 2013 SESPAS. Published by Elsevier Espana. All rights reserved.

Parent's and children's judgements about their outdoor environment in relation to children's injuries.

To explore views of parents and childrens on safety and danger of outdoor environment, and implications for outdoor activities after school. The cross-sectional study was carried out in 2009-2010 and comprised 952 students between 7 and 9 years of age and 942 parents in Tehran. Two separate pre-designed questionnaires were used for children and parent. Data was analysed using SPSS 16. The response rate of parents' and children's questionnaires regarding to socioeconomic deprivation were 830 (88.1%) from 942 and 932 (97.9%) from 952 respectively. Overall, 224 (27.0%) parents believed that the outdoor places children usually play after school are 'not dangerous" while 612 (65.7%) children believed that the streets they usually play on are safe. Besides, 238 (28.7%) parents believed that the volume of traffic in their neighbourhood makes crossing roads difficult. There was no significant difference between the responses of less and more economically deprived parents relating to the presence of dangerous places near their home within less than 5-minute walk (66.8% vs. 62.5%), on general safety describing their areas as being 'not dangerous' (25.6% vs. 18.8%) and who did not regard the volume of traffic in local environment as making crossing the road difficult (55.3% vs. 53.4%). Many parents judged their outdoor places where their children played to be safe. If we assume that the physical environment of the more deprived areas is a more hazardous place than the less deprived areas, it suggests that the risk perception among the more deprived parents is poorer. If so, there is a need to be better informed about hazards in outdoor environment.

The social, economic, and environmental importance of inland fish and fisheries

Though reported capture fisheries are dominated by marine production, inland fish and fisheries make substantial contributions to meeting the challenges faced by individuals, society, and the environment in a changing global landscape. Inland capture fisheries and aquaculture contribute over 40% to the world’s reported finfish production from less than 0.01% of the total volume of water on earth. These fisheries provide food for billions and livelihoods for millions of people worldwide. Herein, using supporting evidence from the literature, we review 10 reasons why inland fish and fisheries are important to the individual (food security, economic security, empowerment), to society (cultural services, recreational services, human health and well-being, knowledge transfer and capacity building), and to the environment (ecosystem function and biodiversity, as aquatic “canaries”, the “green food” movement). However, the current limitations to valuing the services provided by inland fish and fisheries make comparison with other water resource users extremely difficult. This list can serve to demonstrate the importance of inland fish and fisheries, a necessary first step to better incorporating them into agriculture, land-use, and water resource planning, where they are currently often underappreciated or ignored.

Derivation of risk indices and analysis of variablility for the management of incidents involving the transport of nuclear materials in the Northern Seas.

The transport of nuclear or radioactive materials and the presence of nuclear powered vessels pose risks to the Northern Seas in terms of potential impacts to man and environment as well socio-economic impacts. Management of incidents involving actual or potential releases to the marine environment are potentially difficult due to the complexity of the environment into which the release may occur and difficulties in quantifying risk to both man and environment. In order to address this, a state of the art oceanographic model was used to characterize the underlying variability for a specific radionuclide release scenario. The resultant probabilistic data were used as inputs to transfer and dose models providing an indication of potential impacts for man and environment This characterization was then employed to facilitate a rapid means of quantifying risk to man and the environment that included and addressed this variability. The radionuclide specific risk indices derived can be applied by simply multiplying the reported values by the magnitude of the source term and thereafter summing over all radionuclides to provide an indication of total risk.

The Stanford Prison Experiment: Implications for the Care of the "Difficult" Patient.

PubMed

Onishi, So L; Hebert, Randy S

2016-02-01

Approximately 15% of patients are perceived by clinicians as "difficult." Early theories about difficult patients focused on patients' and clinicians' characteristics, often underemphasizing the influence of the environment on patients' behavior. The Stanford Prison Experiment, a classic experiment in the psychology of human behavior, provides a broader systems approach for understanding the environmental influences on patient behavior. A systems approach to the care of the difficult patient takes into consideration not only the patient's characteristics but also the health care environment and the more distal environments (ie, familial, societal, and cultural). Clinicians who are aware of the multilevel impact of these various environments on the behavior of patients are better equipped to understand, address, and hopefully even prevent difficult patient encounters. © The Author(s) 2014.

A methodology to quantitatively evaluate the safety of a glazing robot.

Lee, Seungyeol; Yu, Seungnam; Choi, Junho; Han, Changsoo

A new construction method using robots is spreading widely among construction sites in order to overcome labour shortages and frequent construction accidents. Along with economical efficiency, safety is a very important factor for evaluating the use of construction robots in construction sites. However, the quantitative evaluation of safety is difficult compared with that of economical efficiency. In this study, we suggested a safety evaluation methodology by defining the 'worker' and 'work conditions' as two risk factors, defining the 'worker' factor as posture load and the 'work conditions' factor as the work environment and the risk exposure time. The posture load evaluation reflects the risk of musculoskeletal disorders which can be caused by work posture and the risk of accidents which can be caused by reduced concentration. We evaluated the risk factors that may cause various accidents such as falling, colliding, capsizing, and squeezing in work environments, and evaluated the operational risk by considering worker exposure time to risky work environments. With the results of the evaluations for each factor, we calculated the general operational risk and deduced the improvement ratio in operational safety by introducing a construction robot. To verify these results, we compared the safety of the existing human manual labour and the proposed robotic labour construction methods for manipulating large glass panels.

Characterising Tidal Flow Within AN Energetic Tidal Environment

Neill, S. P.; Goward Brown, A.; Lewis, M. J.

2016-02-01

The Pentland Firth is a highly energetic and complex tidal strait separating the north of Scotland with the Orkney Islands and is a key location for tidal energy exploitation. Topographic features including islands and headlands, combined with bathymetric complexities within the Pentland Firth create turbulent hydrodynamic flows which are difficult to observe. Site selection in tidal energy environments historically focuses on tidal current magnitude. Without consideration for the more complex hydrodynamics of tidal energy environments tidal energy developers may miss the opportunity to tune their devices or create environment specific tidal energy converters in order to harness the greatest potential from site. Fully characterising these tidal energy environments ensures economic energy extraction. Understanding the interaction of energy extraction with the environment will reduce uncertainty in site selection and allow mitigation of any potential environmental concerns. We apply the 3D ROMS model to the Pentland Firth with the aim of resolving uncertainties within tidal energy resource assessment. Flow magnitudes and directions are examined with a focus on tidal phasing and asymmetry and application to sediment dynamics. Using the ROMS model, it is possible to determine the extent to which the tidal resource varies temporally and spatially with tidal energy extraction. Accurately modelling the tidal dynamics within this environment ensures that potential consequences of tidal energy extraction on the surrounding environment are better understood.

A large literature proposes that preferences for exaggerated sex typicality in human faces (masculinity/femininity) reflect a long evolutionary history of sexual and social selection. This proposal implies that dimorphism was important to judgments of attractiveness and personality in ancestral environments. It is difficult to evaluate, however, because most available data come from large-scale, industrialized, urban populations. Here, we report the results for 12 populations with very diverse levels of economic development. Surprisingly, preferences for exaggerated sex-specific traits are only found in the novel, highly developed environments. Similarly, perceptions that masculine males look aggressive increase strongly with development and, specifically, urbanization. These data challenge the hypothesis that facial dimorphism was an important ancestral signal of heritable mate value. One possibility is that highly developed environments provide novel opportunities to discern relationships between facial traits and behavior by exposing individuals to large numbers of unfamiliar faces, revealing patterns too subtle to detect with smaller samples.

Illegal drug use and the economic recession--what can we learn from the existing research?

PubMed

Bretteville-Jensen, Anne Line

2011-09-01

Much research on the use of amphetamine, cocaine and heroin employs individual level data and analyses variations in drug use by factors like personal characteristics, socioeconomic factors, and the social environment. Less attention is given to how these individual responses inter-relate with key macroeconomic variables. From a drug policy perspective however, it is important to also understand the consequences for drug use and drug users of changes in the macroeconomic conditions. As the world is experiencing an economic recession one would like to know whether it will affect the number of drug users and/or consumption frequency and volume amongst established users. There are different channels through which a recession could influence drug consumption; here the main focus is on how an economic downturn may influence drug prices and drug users' incomes. We briefly refer to relevant economic theory before reviewing the research literature. A fall in drug prices and income seem likely. Empirical studies confirm drug users' price responsiveness. Only a few studies have dealt with income elasticity amongst this group. As the price and the income effect may pull in opposite directions, the full effect on drug use is difficult to predict. Still, it seems likely that an economic downturn of the current magnitude could increase the use of drugs. Copyright © 2011 Elsevier B.V. All rights reserved.

Two different anesthesia models were compared in terms of surgical duration, safer outcomes, and economic implications. Third molar surgeries performed with and without a separate dentist anesthesiologist were evaluated by a retrospective data analysis of the surgical operative times. For more difficult surgeries, substantially shorter operative times were observed with the dentist anesthesiologist model, leading to a more favorable surgical outcome. An example calculation is presented to demonstrate economic advantages of scheduling the participation of a dentist anesthesiologist for more difficult surgeries.

The global financial crisis of 2008 has created an economic environment unfavourable to public and corporate economic activity alike, which could not have left space activities unaffected. However, the effects of the crisis upon the space sector have been so far less damaging than anticipated. The following paper presents recent developments in the field of space policies, institutional budgets and commercial activity worldwide, in an effort to improve the understanding of the new trends in commercial and public space activities. It particularly explores the strategies followed by space stakeholders in different countries and regions in order to pursue their planned space programmes in view of difficult financial conditions. Finally, it highlights the differences in the outlook of space activities between established and emerging space-faring nations and attempts to explore their medium-term consequences on an international level. For this purpose, it was based on research conducted in the framework of a recent ESPI report on "Space Policies, Issues and trends in 2009/2010".

Best available techniques (BATs) for oil spill response in the Mediterranean Sea: calm sea and presence of economic activities.

An oil spill is the accidental or intentional discharge of petroleum products into the environment due to human activities. Although oil spills are actually just a little percent of the total world oil pollution problem, they represent the most visible form of it. The impact on the ecosystems can be severe as well as the impact on economic activities. Oil spill cleanup is a very difficult and expensive activity, and many techniques are available for it. In previous works, a methodology based on different kinds of criteria in order to come to the most satisfactory technique was proposed and the relative importance of each impact criterion on the basis of the Saaty's Analytic Hierarchy Process (AHP) was also evaluated. After a review of the best available techniques (BATs) available for oil spill response, this work suggests criteria for BATs' selection when oil spills occur in the Mediterranean Sea under well-defined circumstances: calm sea and presence of economic activities in the affected area. A group of experts with different specializations evaluated the alternative BATs by means of AHP method taking into account their respective advantages and disadvantages.

The concept of sustainable diets, although not new, is gaining increased attention across the globe, especially in relation to projected population growth and growing concerns about climate change. As defined by the FAO (Proceedings of the International Scientific Symposium, Biodiversity and Sustainable Diets 2010; FAO 2012), "Sustainable diets are those diets with low environmental impacts which contribute to food and nutrition security and to healthy life for present and future generations." Consistent and credible science that brings together agriculture, food systems, nutrition, public health, environment, economics, culture, and trade is needed to identify synergies and trade-offs and to inform guidance on vital elements of healthy, sustainable diets. The aim of this article is to review the emerging research on environmental and related economic impacts of dietary patterns, including habitual eating patterns, nutritionally balanced diets, and a variety of different dietary scenarios. Approaches to research designs, methodologies, and data sources are compared and contrasted to identify research gaps and future research needs. To date, it is difficult to assimilate all of the disparate approaches, and more concerted efforts for multidisciplinary studies are needed. © 2015 American Society for Nutrition.

The aim of this article is to review the emerging research on environmental and related economic impacts of dietary patterns, including habitual eating patterns, nutritionally balanced diets, and a variety of different dietary scenarios. Approaches to research designs, methodologies, and data sources are compared and contrasted to identify research gaps and future research needs. To date, it is difficult to assimilate all of the disparate approaches, and more concerted efforts for multidisciplinary studies are needed. PMID:25593141

Energy and environmental problems undermine the potential for sustained economic development and contribute to political and economic instability in the strategically important region surrounding the Caspian and Black Seas. Many organizations supporting efforts to resolve problems in this region have found that consensus building--a prerequisite for action--is a difficult process. Reaching agreement on priorities for investment, technical collaboration, and policy incentives depends upon informed decision-making by governments and local stakeholders. And while vast quantities of data and numerous analyses and reports are more accessible than ever, wading through the many potential sources in search of timely and relevant data ismore » a formidable task. To facilitate more successful data searches and retrieval, this document provides annotated references to over 200 specific information sources, and over twenty primary search engines and data retrieval services, that provide relevant and timely information related to the environment, energy, and economic development around the Caspian and Black Seas. This document is an advance copy of the content that Oak Ridge National Laboratory (ORNL) plans to transfer to the web in HTML format to facilitate interactive search and retrieval of information using standard web-browser software.« less

The business of academic plastic surgery.

Levin, L Scott

2010-07-01

Given the changes in health care economics and the changes in increasing rates of uninsured and undercovered patients in the United States, the revenue stream for all physicians, and particularly those in academic medical centers, is subject to fluctuations that make it difficult to fund the missions of education and research. Often, academic plastic surgeons are required to use clinical revenue to supplement efforts in research and education. A large margin on clinical revenue that was present perhaps 10 or 20 years ago has been eroded by many socioeconomic factors, making it difficult to provide optimal training in academic environments for our residents. In an attempt to ascertain "best in show," a survey was sent to 89 plastic surgery programs that requested information regarding faculty salaries, relative value units, National Institutes of Health support, ancillary revenue support for taking call, and the number of faculty within individual programs. Fifty-three programs responded with completed data. The following practices directly contribute to stable financial environments: external support for call coverage, recruitment support, and gain sharing associated with health system profitability. Coverage agreements with outside facilities can be lucrative if properly negotiated. Paid medical directorships for administrative/clinical oversight are helpful. Payor mixes with high percentages of commercial, managed care, and self-pay (aesthetic) and low percentages of Medicaid are beneficial. Practices with a healthy mix of aesthetic surgery add strength.

Economic Consequences Of Climate Change

Even though the climate conflict resulting from green houses gases (GHG) emissions was evident by the Nineties and the well-known agreements made, their enforcement is more difficult than that of other environmental agreements. That is because measures to reduce GHG emissions interfere with the heart of the economy and the market: energy (in a broader sense than the energy sector as defined by statistics) and economical growth. Analyzing the environmental policy responses to climate change the conclusion is that GHG emission reduction can only be achieved through intensive environmental policy. While extensive environmental protection complements production horizontally, intensive environmental protection integrates into production and the environment vertically. The latter eliminates the source of the pollution, preventing damage. It utilizes the biochemical processes and self-purification of the natural environment as well as technical development which not only aims to produce state-of-the-art goods, but to make production more environmentally friendly, securing a desired environmental state. While in extensive environmental protection the intervention comes from the outside for creating environmental balance, in intensive environmental protection the system recreates this balance itself. Instead of dealing with the consequences and the polluter pays principle, the emphasis is on prevention. It is important to emphasize that climate strategy decisions have complex effects regarding the aspects of sustainability (economical, social, ecological). Therefore, all decisions are political. At present, and in the near future, market economy decisions have little to do with sustainability values under normal circumstances. Taking social and ecological interests into consideration can only be successful through strategic political aims.

Two different anesthesia models were compared in terms of surgical duration, safer outcomes, and economic implications. Third molar surgeries performed with and without a separate dentist anesthesiologist were evaluated by a retrospective data analysis of the surgical operative times. For more difficult surgeries, substantially shorter operative times were observed with the dentist anesthesiologist model, leading to a more favorable surgical outcome. An example calculation is presented to demonstrate economic advantages of scheduling the participation of a dentist anesthesiologist for more difficult surgeries. PMID:28128661

Plant owners face an increasingly difficult and expensive task of updating drawings, both regarding the plant logic and physical layout. Through the use of photogrammetry technology, H-H spectrum has created a complete operating plant data capture service, with the result that the task of recording accurate plant configurations has become assured and economical. The technology has proven to be extremely valuable for the capture of complex piping configurations, as well as entire plant facilities, and yields accuracy within 1/4 inch. The method uses photographs and workstation technology to quickly document and compute the plant layout, with all components, regardless ofmore » size, included in the resulting model. The system has the capability to compute actual 3-D coordinates of any point based on previous triangulations, allowing for an immediate assessment of accuracy. This ensures a consistent level of accuracy, which is impossible to achieve in a manual approach. Due to the speed of the process, the approach is very important in hazardous/difficult environments such as nuclear power facilities or offshore platforms.« less

Breast feeding: social, economic and medical considerations.

Tan, K L

1983-10-01

A certain attitude and lifestyle is needed if breast feeding is to be successful. It must have priority over all other activities save the very basic ones. The rural environment provides a situation in which breast feeding can flourish . With urbanisation and the accompanying change in lifestyle breast feeding becomes very difficult. Since successful breast feeding needs strong motivation, the change in attitude of urbanised wives makes it even more unlikely. The Singapore experience demonstrates this convincingly; even though awareness of the benefits of breast feeding is widespread, the motivation to breast feed is not. Remedial measures should take into consideration the need to motivate the mother and family, the prevention of commercial infant food companies influencing public opinion, and incentives for the working mothers to breast feed.

OPTICAL FIBER SENSOR TECHNOLOGIES FOR EFFICIENT AND ECONOMICAL OIL RECOVERY

DOE Office of Scientific and Technical Information (OSTI.GOV)

Anbo Wang; Kristie L. Cooper; Gary R. Pickrell

2003-06-01

Efficient recovery of petroleum reserves from existing oil wells has been proven to be difficult due to the lack of robust instrumentation that can accurately and reliably monitor processes in the downhole environment. Commercially available sensors for measurement of pressure, temperature, and fluid flow exhibit shortened lifetimes in the harsh downhole conditions, which are characterized by high pressures (up to 20 kpsi), temperatures up to 250 C, and exposure to chemically reactive fluids. Development of robust sensors that deliver continuous, real-time data on reservoir performance and petroleum flow pathways will facilitate application of advanced recovery technologies, including horizontal and multilateralmore » wells. This is the final report for the four-year program ''Optical Fiber Sensor Technologies for Efficient and Economical Oil Recovery'', funded by the National Petroleum Technology Office of the U.S. Department of Energy, and performed by the Center for Photonics Technology of the Bradley Department of Electrical and Computer Engineering at Virginia Tech from October 1, 1999 to March 31, 2003. The main objective of this research program was to develop cost-effective, reliable optical fiber sensor instrumentation for real-time monitoring of various key parameters crucial to efficient and economical oil production. During the program, optical fiber sensors were demonstrated for the measurement of temperature, pressure, flow, and acoustic waves, including three successful field tests in the Chevron/Texaco oil fields in Coalinga, California, and at the world-class oil flow simulation facilities in Tulsa, Oklahoma. Research efforts included the design and fabrication of sensor probes, development of signal processing algorithms, construction of test systems, development and testing of strategies for the protection of optical fibers and sensors in the downhole environment, development of remote monitoring capabilities allowing real-time monitoring of the field test data from virtually anywhere in the world, and development of novel data processing techniques. Comprehensive testing was performed to systematically evaluate the performance of the fiber optic sensor systems in both lab and field environments.« less

Importance of adaptation and genotype × environment interactions in tropical beef breeding systems.

PubMed

Burrow, H M

2012-05-01

This paper examines the relative importance of productive and adaptive traits in beef breeding systems based on Bos taurus and tropically adapted breeds across temperate and (sub)tropical environments. In the (sub)tropics, differences that exist between breeds in temperate environments are masked by the effects of environmental stressors. Hence in tropical environments, breeds are best categorised into breed types to compare their performance across environments. Because of the presence of environmental stressors, there are more sources of genetic variation in tropical breeding programmes. It is therefore necessary to examine the genetic basis of productive and adaptive traits for breeding programmes in those environments. This paper reviews the heritabilities and genetic relationships between economically important productive and adaptive traits relevant to (sub)tropical breeding programmes. It is concluded that it is possible to simultaneously genetically improve productive and adaptive traits in tropically adapted breeds of beef cattle grazed in tropical environments without serious detrimental consequences for either adaptation or production. However, breed-specific parameters are required for genetic evaluations. The paper also reviews the magnitude of genotype × environment (G × E) interactions impacting on production and adaptation of cattle, where 'genotype' is defined as breed (within a crossbreeding system), sire within breed (in a within-breed selection programme) or associations between economically important traits and single nucleotide polymorphisms (SNPs - within a marker-assisted selection programme). It is concluded that re-ranking of breeds across environments is best managed by the use of the breed type(s) best suited to the particular production environment. Re-ranking of sires across environments is apparent in poorly adapted breed types across extreme tropical and temperate environments or where breeding animals are selected in a temperate environment for use in the (sub)tropics. However, G × E interactions are unlikely to be of major importance in tropically adapted beef cattle grazed in either temperate or (sub)tropical environments, although sex × environment interactions may provide new opportunities for differentially selecting to simultaneously improve steer performance in benign environments and female performance in harsher environments. Early evidence suggests that re-ranking of SNPs occurs across temperate and tropical environments, although their magnitude is still to be confirmed in well-designed experiments. The major limitation to genetic improvement of beef cattle over the next decade is likely to be a deficiency of large numbers of accurately recorded phenotypes for most productive and adaptive traits and, in particular, for difficult-to-measure adaptive traits such as resistance to disease and environmental stressors.

We conducted a qualitative study to gather information on adolescent views of how a 20% tax on sugar-sweetened beverages (SSBs) would affect adolescents' consumption of SSBs. The role of habit in consumption of SSBs was also explored. We held 3 focus groups with students from various racial/ethnic groups (N = 22) in grades 6 through 8 at a Michigan middle school. Data on demographic characteristics and beverage consumption were collected. Focus group discussions, guided by the Theory of Planned Behavior, explored adolescent views of a 20% tax on SSBs and the tax's effect on adolescents' consumption of these beverages. Focus groups were recorded and recordings transcribed verbatim. Data were coded and analyzed using NVivo software. Students understood the short- and long-term advantages and disadvantages of drinking SSBs. They understood that the opinions of those around them about SSBs might be affected by personal consumption. Students also understood the personal and economic effects of a 20% tax on SSBs, although the economics of a tax confused some. Students indicated that habit and environment could make reducing consumption of SSBs difficult, but they also gave suggestions, using habit and environment, to reduce consumption. Most students reported that they would decrease their consumption of SSBs if a 20% tax were implemented. Taxes on SSBs could be used, with other strategies, to reduce adolescents' high level of SSB consumption.

Forgotten public health impacts of cancer - an overview.

2017-12-20

Cancer is one of the diseases of greatest concern in developed countries and much effort has been invested in discovering and developing therapeutics for curing cancer. Despite the improvements in antineoplastic therapeutics in the last decades, cancer is still one of the most harmful diseases worldwide. The global burden of cancer also implies financial costs: these can be direct costs, such as those related to treatment, care, and rehabilitation and indirect, which include the loss of economic output due to missed work (morbidity costs) and premature death (mortality costs). There are also hidden costs such as health insurance premiums and nonmedical expenses that are worth noting. This paper intends to present an overview of the generally forgotten impacts that the increasing number of cancer cases can have on the environment, workers who handle antineoplastic drugs, and health services. The knowledge available of each of the impacts will be addressed and discussed regarding the expected development. Overall, lessons learnt reflect on the impact of cancer through aspects not commonly evidenced in the literature or even considered in socio-economic analysis, in part due to the fact that these are difficult to contemplate in direct and indirect cancer costs already defined. Attention may be drawn to the need of continuous investment in prevention to reduce the negative impact on the environment, and in the health of workers who handle antineoplastic drugs for patients' treatment.

Better Redd than Dead: Optimizing Reservoir Operations for Wild Fish Survival During Drought

Extreme droughts are difficult to predict and may incur large economic and ecological costs. Dam operations in drought usually consider minimizing economic costs. However, dam operations also offer an opportunity to increase wild fish survival under difficult conditions. Here, we develop a probabilistic optimization approach to developing reservoir release schedules to maximize fish survival in regulated rivers. A case study applies the approach to wild Fall-run Chinook Salmon below Folsom Dam on California's American River. Our results indicate that releasing more water early in the drought will, on average, save more wild fish over the long term.

Economic and environmental review of Waste-to-Energy systems for municipal solid waste management in medium and small municipalities.

2017-09-01

The application of Directive 2008/98/CE on Municipal Solid Waste (MSW) implies the need to introduce technologies to generate energy from waste. Incineration, the most widely used method, is difficult to implement in low populated areas because it requires a large amount of waste to be viable (100,000 tons per year). This paper analyses the economic and environmental costs of different MSW-to-Energy technologies (WtE) in an area comprising of 13 municipalities in southern Spain. We analyse anaerobic digestion (Biomethanization), the production of solid recovered fuel (SRF) and gasification, and compare these approaches to the present Biological Mechanical Treatment (BMT) with elimination of the reject in landfill, and incineration with energy recovery. From an economic standpoint the implementation of WtE systems reduces the cost of running present BMT systems and incineration; gasification presents the lowest value. From the environmental standpoint, Life Cycle Assessment shows that any WtE alternatives, including incineration, present important advantages for the environment when compared to BMT. Finally, in order to select the best alternative, a multi-criteria method is applied, showing that anaerobic digestion is the optimal solution for the area studied. Copyright © 2017 Elsevier Ltd.

Can we manage ecosystems in a sustainable way?

NASA Astrophysics Data System (ADS)

Rice, Jake

Fisheries have often become unsustainable, despite efforts of policy, management, and science. FAO has reviewed this undesirable pattern and identified six major factors contributing to unsustainability: inappropriate incentives, high demand for limited resources, poverty and lack of alternatives, complexity and lack of knowledge, lack of effective governance, and interactions of fisheries sector with other sectors and the environment. It also identified eight classes of actions that provide pathways to addressing the factors causing unsustainability of fisheries: allocation of rights; transparent, participatory management; support for science, enforcement and planning; equitable distribution of benefits; integrated policy development; application of precaution; building capacity and public understanding; and market incentives and economic instruments. The review highlighted that "sustainability" is a multi-dimensional concept (economic, social, ecological, and institutional), and measures implemented to address problems on one dimension of sustainability will move the fishery in a negative direction in at least one other dimension. In this paper I apply the FAO framework to the whole ecosystem. For each factor of unsustainability, I consider whether redefining the sustainability problem to the greater ecosystem makes the factor more or less serious as a threat to sustainability. For each pathway to improvement I consider whether the redefinition of the problem makes the pathway more or less effective as a management response to the threat. Few of the factors of unsustainability becomes easier to address at the ecosystem scale, and several of them become much more difficult. Of the combinations of pathways of responses and factors of unsustainability, more than two thirds of them become more difficult to apply, and/or have even greater negative impacts on other dimensions of sustainability. Importantly, the most promising pathways for addressing unsustainability of fisheries alone become particularly hard to apply when addressing unsustainability at the ecosystem scale. The ecosystem approach may be a necessary step to take, because the problem of sustainable use of fish stocks may not be solvable at the scale it has been defined historically. However these results imply that moving to an ecosystem scale of considerations is going to make the search for sustainability even more difficult. Moreover there is still no guarantee that a solution can be found — at least not any solution without major reductions in social and economic expectations.

Innovations in Science Education in Europe

2001-12-01

At many European Universities, the retention of skilled science graduates is hindered mainly by organisational structures. In particular, women students are often under-represented in sciences, and career progression is in general difficult. The linear system of knowhow transfer is inefficient from the pedagogical point of view and unsatisfactory for many students. Owing to fast changes in society and the working environment, a re-building of curricula in tertiary education (including University Education) has begun. Conceptual visions aim at influencing the investment in the largely untapped human capital and preparing the students for quick adaptation and enhanced flexiblity. Traditional methods of classroom teaching and knowhow transfer are increasingly complemented by New Learning Technologies and Mentoring. The EU Project INDECS (Potentials of Interdisciplinary Degree Courses in Engineering, Information Technology, Natural and Socio-Economic Sciences in a Changing Society) examines such pedagogical aspects in European degree courses combining engineering, IT, physical sciences and socio-economic sciences. Inclusion of specific IT and social science topics in modular form is examined. How innovation in University Teaching will meet the attractiveness to both students and employers in Europe is major focus of the study.

The economics of new age arthroplasty: can we afford it?

PubMed

Sculco, Thomas P

2010-09-07

New technology in joint replacement design and materials adds cost that must be documented by improved outcomes. This is not always the case as the recent metal/metal data has shown. The current economics of arthroplasty have put increasing financial pressure on hospitals and will progress under new health care legislation. New technology must be cost-effective and this will be increasingly difficult in an era of outstanding long-term results with current designs. Cost may necessitate less expensive alternatives, eg, generic implants, in arthroplasty patients. Joint replacement surgery has evolved over the past 4 decades into a highly successful surgical procedure. Earlier designs and materials that demonstrated inferior functional and long-term results have disappeared in a Darwinian fashion. Through this evolutionary process many of the current designs have proven efficacy and durability. Current outcome data indicates that hip and knee designs demonstrate 90% to 95% success rates at 15-year follow-up. Technologic advances are necessary to improve implant design and materials, however, only in an environment of reduced reimbursement to hospitals can the increase cost be justified.

The City of Los Angeles faces a challenge to assist industrial facilities to minimize and manage hazardous materials in order to sustain the local economy and natural environment. Industrial facilities in Los Angeles County released into the environment or transferred off-site 103,442,074 tons of hazardous materials and waste in 1988. This enormous quantity of hazardous waste requires generators to be in compliance with several environmental regulatory agencies.

Quantifying hazardous waste minimization progress is extremely difficult and complex. However, the HTM Office anticipates that if the challenge of pollution prevention is successful, more businesses will decide to remain in the region and Los Angeles residents will feel convinced that industry is making good faith efforts to protect the environment. Pollution prevention is a long term solution for the hazardous waste crisis that society has only recently recognized.« less

[Economic damage caused by lowered prices in the agro-food sector in areas contaminated by radioactive materials leaked from the nuclear power plant severely damaged by the 2011 Great East Japan Earthquake--consideration from the viewpoints of epidemiology, economics and social psychology].

Large amounts of radioactive materials were leaked into the environment from the Fukushima Daiichi Nuclear Power Plant (FDNPP) of the Tokyo Electric Power Company, which was severely damaged by the 2011 Tohoku Region Pacific Coast Earthquake and accompanying tsunami. Economic damage due to lowered prices and supplies of food products produced in the areas contaminated by the radioactive materials leaked from the damaged FDNPP to the agro-food sector in the affected areas is notable. In Japanese, this is known as fuhyo higai. In this study, we investigated fuhyo higai from the viewpoints of epidemiology, economics, and social psychology in an effort to seek solutions. Information was obtained from articles in print and on the Internet. Fuhyo higai, or economic damage of the agro-food sector, which is the main industry in the contaminated areas, is serious because it is difficult to reassure the general population regarding food safety. This fuhyo higai does not derive solely from rumor. It has been reported that improving the science literacy of the general population is important as a countermeasure against fuhyo higai, but this may not be effective because of the human social structure and behavior of people who seek subjective safety. Almost all radiological laboratory results of samples of food produced in the contaminated areas were below detectable limits. Very high values were rarely detected. In general, information about the dose-response relationship is obtained under the assumption that there may be error in the response but not in the dose. The rare cases of extremely high radiological values of food samples from the contaminated areas may correspond to large errors in dose. However, it is difficult to deny a high-dose risk. The reported information on the dose-response relationship obtained under the assumption that there is no error in dose is not sufficient. Thus, response, i.e., health risk, cannot be correctly estimated. This leads the general population to choose food products from areas far from the FDNPP over those from the contaminated areas. In order to resolve this problem, thorough decontamination of radioactive areas, including large forests, is necessary for the market to regain competitiveness to the level it was before the accident. The cost of such decontamination is enormous and requires much labor.

Healthcare disparities are a major challenge for hospital and healthcare system leadership. Leaders must possess vision, visibility, and ability to drive organizational change toward an environment that fosters diversity and cultural competence. As challenging economic conditions force management to make difficult budgetary decisions, the integration of equity into the organization's core mission and strategic process is essential for sustainability. Building organizational capacity requires systematic actions including workforce composition, training and development, and policy advocacy. This article offers perspectives on the current state of diversity in hospitals, exemplars from pediatric hospitals, and considerations for the future. Healthcare leaders are influential in shaping the future of the organization through strategic planning and resource allocation to those efforts that enhance services, programs, and processes that support a culture of diversity and equity.

Commercial fishing industry deaths - forensic issues.

PubMed

Byard, Roger W

2013-04-01

The commercial fishing industry has one of the highest injury and mortality rates of all occupational areas. This results from the nature of the work involving vessels often manned by only a few individuals who are working with heavy-duty equipment in dangerous environments at all hours. Economic pressures may force inappropriately geared vessels to operate further out to sea than is safe. Deaths result from a wide variety of situations involving vessel loss, falls overboard, fire and explosions, cable entanglements and gas exposure. Autopsies are often difficult as there are no diagnostic features of either drowning or hypothermia and features may be obscured by putrefaction and postmortem animal predation. The forensic implications of deaths in the fishing industry are reviewed. Copyright © 2012 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

Economic networks: the new challenges.

Schweitzer, Frank; Fagiolo, Giorgio; Sornette, Didier; Vega-Redondo, Fernando; Vespignani, Alessandro; White, Douglas R

2009-07-24

The current economic crisis illustrates a critical need for new and fundamental understanding of the structure and dynamics of economic networks. Economic systems are increasingly built on interdependencies, implemented through trans-national credit and investment networks, trade relations, or supply chains that have proven difficult to predict and control. We need, therefore, an approach that stresses the systemic complexity of economic networks and that can be used to revise and extend established paradigms in economic theory. This will facilitate the design of policies that reduce conflicts between individual interests and global efficiency, as well as reduce the risk of global failure by making economic networks more robust.

The Positive Effect of Resilience on Stress and Business Outcomes in Difficult Work Environments.

PubMed

Shatté, Andrew; Perlman, Adam; Smith, Brad; Lynch, Wendy D

2017-02-01

To examine whether resilience has a protective effect in difficult work environments. A survey of 2063 individuals measured individual resilience, stress, burnout, sleep problems, likelihood of depression, job satisfaction, intent to quit, absences, and productivity. It also measured work characteristics: job demands, job influence, and social support. Multivariate and logistic regression models examined the main effects and interactions of resilience and job characteristics. High strain work environments (high demand, low influence, and low support) have an unfavorable effect on all outcomes. Resilience has a protective effect on all outcomes. For stress, burnout, and sleep, higher resilience has a more protective effect under low-strain conditions. For depression, absence and productivity, resilience has a more protective effect when job strain is high. Workers with high resilience have better outcomes in difficult work environments.

Valuation of biodiversity effects from reduced pesticide use.

PubMed

Schou, Jesper S; Hasler, Berit; Nahrstedt, Birgit

2006-04-01

This study deals with the effects on biodiversity of pesticide-free buffer zones along field margins. Using choice modeling, the majority of respondents to a survey on pesticide use in the environment are willing to accept an increase in the price of bread if the survival of partridge chicks and the number of wild plants increase. The study identifies the need for further empirical work with respect to methodological validation, price estimation, and the use of survey results in policy analysis. In particular, the environmental effects of pesticide use are complex and, therefore, present difficult challenges when presenting information to lay people. Forty-one percent of respondents changed their responses regarding willingness to pay more for bread when references to pesticide use were introduced in the questionnaire. This indicates that scenarios depicting changes in pesticide use can be difficult to present to lay people in an economically rational and well-defined context. Thus, in the study of valuation related to changes in pesticide use, much attention should be devoted to the design and definition of the context. Furthermore, the effects of providing different background information, e.g., with or without the mention of pesticides, should be tested.

Handling e-waste in developed and developing countries: initiatives, practices, and consequences.

PubMed

Sthiannopkao, Suthipong; Wong, Ming Hung

2013-10-01

Discarded electronic goods contain a range of toxic materials requiring special handling. Developed countries have conventions, directives, and laws to regulate their disposal, most based on extended producer responsibility. Manufacturers take back items collected by retailers and local governments for safe destruction or recovery of materials. Compliance, however, is difficult to assure, and frequently runs against economic incentives. The expense of proper disposal leads to the shipment of large amounts of e-waste to China, India, Pakistan, Nigeria, and other developing countries. Shipment is often through middlemen, and under tariff classifications that make quantities difficult to assess. There, despite the intents of national regulations and hazardous waste laws, most e-waste is treated as general refuse, or crudely processed, often by burning or acid baths, with recovery of only a few materials of value. As dioxins, furans, and heavy metals are released, harm to the environment, workers, and area residents is inevitable. The faster growth of e-waste generated in the developing than in the developed world presages continued expansion of a pervasive and inexpensive informal processing sector, efficient in its own way, but inherently hazard-ridden.

CEO must have authority to coordinate governance, management, medical staff.

PubMed

Johnson, R L

1984-04-01

As hospitals attempt to survive in today's new competitive environment, they will find that the traditional organizational structure does not work. This structure can be characterized as a three-legged stool. Governance, management, and medical staff existed in relative harmony, with each able to attend to its own distinct, separate responsibilities. The medical staff regulated itself, the governing board had no serious difficulties in coping with the institution's finances, and the CEO was concerned solely with the physical plant and hospital personnel. In a riskless economic environment, this three-legged stool could remain stable. In the coming years,however, a hospital will need a clear-cut, identifiable leader if it is to survive. To centralize authority primarily in the CEO's hands will be a difficult step for nonprofit hospitals, particularly those sponsored by religious institutions, because of their tradition of operating much as a charitable social agency rather than a business. But this step must be taken, even to the extent of naming the CEO as chairman of the board, for a leader is required who has the authority to make quick decisions in the competitive marketplace. Timeliness is of strategic importance in such an environment, and governing boards increasingly will find it impossible to make timely decisions on a collective basis. Moreover, CEOs will have to coordinate the activities of management, medical staff, and the governing board. They will need to play a strong role in ensuring that target levels in DRG costs are met, and they will need the authority to mediate in issues in which the hospital's economic interests are pitted against physicians'.(ABSTRACT TRUNCATED AT 250 WORDS)

Cleaner production: Minimizing hazardous waste in Indonesia

DOE Office of Scientific and Technical Information (OSTI.GOV)

Bratasida, D.L.

In the second long-term development plan, industry plays a significant role in economic growth. In Indonesia, industries grow very fast; such fast growth can adversely effect the environment. Exploitation of assets can mean depletion of natural resources and energy, which, if incorrectly managed, can endanger human life and the environment. The inefficient use of natural resources will accelerate their exhaustion and generate pollution, resulting in environmental damage and threats to economic development and human well being. In recent years, changes in the approach used to control pollution have been necessary because of the increasing seriousness of the problems. Initial environmentalmore » management strategies were based on a carrying capacity approach; the natural assimilative capacity accommodated the pollution load that was applied. The environmental management strategies adopted later included technologies applied to the end of the discharge point (so-called {open_quotes}end-of-pipe{close_quotes} treatments). Until now, environmental management strategies focused on end-of-pipe approaches that control pollutants after they are generated. These approaches concentrate on waste treatment and disposal to control pollution and environmental degradation. However, as industry develops, waste volumes continue to increase, thereby creating further environmental problems. In addition, the wastes produced tend to have more complex characteristics and are potentially more difficult to treat for a reasonable cost. There are often technical and financial obstacles to regulatory compliance if waste treatment is relied on as the only means of achieving environmental objectives. Consequently, the reactive end-of-pipe treatment approach has been changed to a proactive cleaner production approach. This approach is based on the concept of sustainable development and is designed to prevent pollution as well as to protect natural resources and the quality of the environment.« less

Environmental stress, oxytocin receptor gene (OXTR) polymorphism, and mental health following collective stress.

PubMed

Lucas-Thompson, Rachel G; Holman, E Alison

2013-04-01

We examined whether the oxytocin receptor gene (OXTR) single nucleotide polymorphism (SNP) rs53576 genotype buffers the combined impact of negative social environments (e.g., interpersonal conflict/constraint) and economic stress on post-traumatic stress (PTS) symptoms and impaired daily functioning following collective stress (September 11th terrorist attacks). Saliva was collected by mail and used to genotype 704 respondents. Participants completed Web-based assessments of pre-9/11 mental health, acute stress 9-23 days after 9/11, the quality of social environments 1 year post-9/11, economic stress 18 months post-9/11, and PTS symptoms and impaired functioning 2 and 3 years post-9/11. Interactions between negative social environments and economic stress were examined separately based on OXTR rs53576 genotype (GG vs. any A allele). For individuals with an A allele, a negative social environment significantly increased PTS symptoms without regard to the level of economic stress experienced. However, for respondents with a GG genotype, negative social environments predicted elevated PTS symptoms only for those also experiencing high economic stress. Gender moderated associations between negative social environments, economic stress, and impaired functioning. The functioning of females was most affected by negative social environments regardless of genotype and economic stress, whereas the functioning of males was differentially susceptible to economic stress depending on OXTR genotype and negative social environments. These findings suggest that it is important to consider the combined impact of gender and ongoing stress in different domains as moderators of genetic vulnerability following collective stress.

A narrative review on the effect of economic downturns on the nursing labour market: implications for policy and planning

PubMed Central

2012-01-01

Economic downturns and recession lead to budget cuts and service reductions in the healthcare sector which often precipitate layoffs and hiring freezes. Nurses, being the largest professional group in healthcare, are strongly affected by cost reductions. Economic downturns destabilize the nursing labour market with potential negative outcomes, including serious shortages, extending beyond the recessionary period. The objectives of this manuscript are to provide an overview of the potential short- and long-run impact of economic downturns on the supply and demand of nurses, and present healthcare decision makers with a framework to enhance their ability to strategically manage their human resources through economic cycles. A narrative review of the literature on the effects of economic downturns on the nursing labour market in developed countries was carried out with a special focus on studies offering a longitudinal examination of labour force trends. Analysis indicates that economic downturns limit the ability of public payers and institutions to finance their existing health workforce. As salaried healthcare workers, nurses are especially susceptible to institutional budget cuts. In the short run, economic downturns may temporarily reduce the demand for and increase the supply of nurses, thereby influencing nursing wages and turnover rates. These effects may destabilise the nursing labour market in the long run. After economic downturns, the market would quickly display the pre-recessionary trends and there may be serious demand–supply imbalances resulting in severe shortages. Potential long-term effects of recession on the nursing labour market may include a downsized active workforce, difficulty in retaining younger nurses, a decreased supply of nurses and workforce casualisation. Lack of understanding of labour market dynamics and trends might mislead policy makers into making misinformed workforce downsizing decisions that are often difficult and expensive to reverse. In the aftermath of an economic downturn, the costs of attracting nurses back often outweigh the short term cost savings. Effective management should support the nursing workforce by creating attractive and stable work environments to retain nurses at a manageable cost. PMID:22905739

Preliminary research on quantitative methods of water resources carrying capacity based on water resources balance sheet

Wang, Yanqiu; Huang, Xiaorong; Gao, Linyun; Guo, Biying; Ma, Kai

2018-06-01

Water resources are not only basic natural resources, but also strategic economic resources and ecological control factors. Water resources carrying capacity constrains the sustainable development of regional economy and society. Studies of water resources carrying capacity can provide helpful information about how the socioeconomic system is both supported and restrained by the water resources system. Based on the research of different scholars, major problems in the study of water resources carrying capacity were summarized as follows: the definition of water resources carrying capacity is not yet unified; the methods of carrying capacity quantification based on the definition of inconsistency are poor in operability; the current quantitative research methods of water resources carrying capacity did not fully reflect the principles of sustainable development; it is difficult to quantify the relationship among the water resources, economic society and ecological environment. Therefore, it is necessary to develop a better quantitative evaluation method to determine the regional water resources carrying capacity. This paper proposes a new approach to quantifying water resources carrying capacity (that is, through the compilation of the water resources balance sheet) to get a grasp of the regional water resources depletion and water environmental degradation (as well as regional water resources stock assets and liabilities), figure out the squeeze of socioeconomic activities on the environment, and discuss the quantitative calculation methods and technical route of water resources carrying capacity which are able to embody the substance of sustainable development.

Conroy, Stephen J; Emerson, Tisha L N

2014-12-01

We test whether macroeconomic conditions affect individuals' willingness to pay for environmental quality improvements. Improvements in environmental quality, like everything, come at a cost. Individuals facing difficult economic times may be less willing to make trade-offs required for improvements in environmental quality. Using somewhat different methodologies and shorter time frames, prior investigations have generally found a direct relationship between willingness to pay for environmental improvements and macroeconomic conditions. We use a nearly 40-year span (27 periods) of the General Social Survey (1974-2012) to estimate attitudes toward environmental spending while controlling for U.S. macroeconomic conditions and respondent-specific factors such as age, gender, marital status, number of children, residential location, educational attainment, personal financial condition, political party affiliation and ideology. Macroeconomic conditions include one-year lagged controls for the unemployment rate, the rate of economic growth (percentage change in real GDP), and an indicator for whether the U.S. economy was experiencing a recession. We find that, in general, when economic conditions are unfavorable (i.e., during a recession, or with higher unemployment, or lower GDP growth), respondents are more likely to believe the U.S. is spending too much on "improving and protecting the environment". Interacting lagged macroeconomic controls with respondent's income, we find that these views are at least partially offset by the respondent's own economic condition (i.e., their own real income). Our findings are consistent with the notion that environmental quality is a normal, or procyclical good, i.e., that environmental spending should rise when the economy is expanding and fall during economic contractions.

Environment and development of respiratory allergy. II. Indoors.

D'Amato, G; Liccardi, G; D'Amato, M

1994-12-01

Even if it is difficult to obtain correct epidemiological evidence, there is a body of evidence which suggests that the frequency of allergic respiratory diseases is increasing. The majority of atopic patients, in particular in childhood and adolescence, develop immunoglobulin E (IgE) antibodies with clinical symptoms to aeroallergens, such as those derived from house dust mites, pollens and pets. Since, in the economically-developed countries individuals spend most of their time indoors (home, school and workplace), indoor pollutants (tobacco smoke etc.) and allergens (house dust mite, cats, etc.) are the most important source of exposure. Indoor allergens are associated with a wide variety of particles in a broad size range, only some of which are microscopically identifiable, culturable, or detectable with existing immunoassay. Evaluation of indoor allergens requires both air and source sampling, and several different analytical techniques. It is likely that the increased prevalence of allergy and asthma may be caused in the indoor environment by the synergistic action of air pollution (in particular derived from tobacco smoking) with allergic sensitization. Passive smoking in infancy has also been involved in the airways allergic sensitization to common aeroallergens.

Willmott, M; Womack, J; Hollingworth, W; Campbell, R

2016-06-01

Amid local government budget cuts, there is concern that the ring-fenced public health grant is being appropriated, and Directors of Public Health (DsPH) find it difficult to make the case for investment in public health activity. This paper describes what DsPH are making the case for, the components of their case and how they present the case for public health. Thirteen semi-structured telephone interviews and a group discussion were carried out with DsPH (November 2013 to May 2014) in the Southern region of England. DsPH make the case for control of the public health grant and investing in action on wider determinants of health. The cases they present incorporate arguments about need, solutions and their effectiveness, health outcomes, cost and economic impact but also normative, political arguments. Many types of evidence were used to substantiate the cases; evidence was carefully framed to be accessible and persuasive. DsPH are responding to a new environment; economic arguments and evidence of impact are key components of the case for public health, although multiple factors influence local government (LG) decisions around health improvement. Further evidence of economic impact would be helpful in making the case for public health in LG. © The Author 2015. Published by Oxford University Press on behalf of Faculty of Public Health.

Improving the quality of mass produced maps

USGS Publications Warehouse

Simley, J.

2001-01-01

Quality is critical in cartography because key decisions are often made based on the information the map communicates. The mass production of digital cartographic information to support geographic information science has now added a new dimension to the problem of cartographic quality, as problems once limited to small volumes can now proliferate in mass production programs. These problems can also affect the economics of map production by diverting a sizeable portion of production cost to pay for rework on maps with poor quality. Such problems are common to general industry-in response, the quality engineering profession has developed a number of successful methods to overcome these problems. Two important methods are the reduction of error through statistical analysis and addressing the quality environment in which people work. Once initial and obvious quality problems have been solved, outside influences periodically appear that cause adverse variations in quality and consequently increase production costs. Such errors can be difficult to detect before the customer is affected. However, a number of statistical techniques can be employed to detect variation so that the problem is eliminated before significant damage is caused. Additionally, the environment in which the workforce operates must be conductive to quality. Managers have a powerful responsibility to create this environment. Two sets of guidelines, known as Deming's Fourteen Points and ISO-9000, provide models for this environment.

2015-05-01

It is one of the important strategies in the new period of national poverty alleviation and development to maintain the basic balance between the ecological environment and economic development, and to promote the coordinated sustainable development of economy and ecological environment. Taking six contiguous special poverty-stricken areas as the study areas, a coupling coordination evaluation method between eco-environment quality and economic development level in contiguous special poverty-stricken areas was explored in this paper. The region' s ecological poverty index system was proposed based on the natural attribute of ecological environment, and the ecological environment quality evaluation method was built up by using AHP weighting method, followed by the design of the coupling coordination evaluation method between the ecological environment indices and the county economic poverty comprehensive indices. The coupling coordination degrees were calculated and their spatial representation differentiations were analyzed respectively at district, province, city, and county scales. Results showed that approximately half of the counties in the study areas achieved the harmoniously coordinated development. However, the ecological environmental quality and the economic development in most counties could not be synchronized, where mountains, rivers and other geographic features existed roughly as a dividing line of the coordinated development types. The phenomena of dislocation between the ecological environment and economic development in state-level poor counties were more serious than those of local poor counties.

A Bump on a Bump? Emerging Intuitions Concerning the Relative Difficulty of the Sciences

PubMed Central

Keil, Frank C.; Lockhart, Kristi L.; Schlegel, Esther

2011-01-01

In 4 studies, the authors examined how intuitions about the relative difficulties of the sciences develop. In Study 1, familiar everyday phenomena in physics, chemistry, biology, psychology, and economics were pretested in adults, so as to be equally difficult to explain. When participants in kindergarten, Grades 2, 4, 6, and 8, and college were asked to rate the difficulty of understanding these phenomena, children revealed a strong bias to see natural science phenomena as more difficult than those in psychology. The perceived relative difficulty of economics dropped dramatically in late childhood. In Study 2, children saw neuroscience phenomena as much more difficult than cognitive psychology phenomena, which were seen as more difficult than social psychology phenomena, even though all phenomena were again equated for difficulty in adults. In Study 3, we explored the basis for these results in intuitions about common knowledge and firsthand experience. Study 4 showed that the intuitions about the differences between the disciplines were based on intuitions about difficulty of understanding and not on the basis of more general intuitions about the feasibility or truth of the phenomena in question. Taken together, in the studies, the authors find an early emerging basis for judgments that some sciences are intrinsically more difficult than others, a bias that may persevere in adults in subtler forms in such settings as the courtroom.

2013-12-01

Few studies have addressed how political and economic contexts shape the effects of health services and environment, such that a politically and economically unstable society, despite having sufficient health professionals and facilities, finds it difficult to transfer health resources into actual population health performance. We examined whether political and economic characteristics moderate the effects of health services on infant mortality rates (IMR) in less-developed countries. This study used a longitudinal ecological study design and focused on 46 less-developed countries during the 30-year period from 1980 to 2009. Data were derived from World Development Indicators, the United Nations Commodity Trade Statistics Database and the Polity IV project. Lagged dependent variable panel regression models were used to increase the causal inferences. Random intercept models were used to accommodate the possible problem of a serial correlation of errors because of the repeated measurements. After controlling for baseline IMR and other socioeconomic variables, our study showed that democracy had a direct effect on IMR, and a moderating effect on the relationship between health services and IMR. The effects of health services on IMR were stronger for countries with a lower level of democracy than for countries with a higher level of democracy in the 10-year models. Compared with other trade-rated characteristics, democracy is a more robust predictor of long-term IMR in less-developed countries. Our study provides additional evidence that democracy has direct effects on IMR and further showed that democracy can modify the effects of health services on IMR.

Previous studies have shown that satellite servicing is cost effective; however, all of these studies were of different formats, dollar year, learning rates, availability, etc. Therefore, it was difficult to correlate any useful trends from these studies. The reviewed study was initiated to correlate the economic data into a common data base, using a common set of assumptions. A selected set of existed funded programs was then analyzed to provide an independent analysis of the servicing options and potential economic benefits.

Standardizing economic analysis in prevention will require substantial effort.

PubMed

Guyll, Max

2014-12-01

It is exceedingly difficult to compare results of economic analyses across studies due to variations in assumptions, methodology, and outcome measures, a fact which surely decreases the impact and usefulness of prevention-related economic research. Therefore, Crowley et al. (Prevention Science, 2013) are precisely correct in their call for increased standardization and have usefully highlighted the issues that must be addressed. However, having made the need clear, the questions become what form the solution should take, and how should it be implemented. The present discussion outlines the rudiments of a comprehensive framework for promoting standardized methodology in the estimation of economic outcomes, as encouraged by Crowley et al. In short, a single, standard, reference case approach should be clearly articulated, and all economic research should be encouraged to apply that standard approach, with results from compliant analyses being reported in a central archive. Properly done, the process would increase the ability of those without specialized training to contribute to the body of economic research pertaining to prevention, and the most difficult tasks of predicting and monetizing distal outcomes would be readily completed through predetermined models. These recommendations might be viewed as somewhat forcible, insomuch as they advocate for prescribing the details of a standard methodology and establishing a means of verifying compliance. However, it is unclear that the best practices proposed by Crowley et al. will be widely adopted in the absence of a strong and determined approach.

Improving agricultural commodity supply-chain to promote economic activities in rural area

NASA Astrophysics Data System (ADS)

Padjung, R.

2018-05-01

Long supply chain of agricultural commodities has become concern to governments particularly in large countries such as Indonesia as it causes high price disparity between farm-gate and retailer. Policies to overcome such problem are usually by shortening the chain, by which farmers sell the products directly to retailers. Using an action research in AEDEF (Aceh Economic Development Financing Facilities) Program, conducted in the province of Nangro Aceh Darussalam (NAD) Indonesia, the paper shows that shortening the commodity supply chain is not the best solution to such problem, as it causes loss of jobs in the villages. High price disparity between farm-gate and retailer is not necessary brought about by long supply-chain but by the efficiency of the chain instead. Efficiency of the chain can be improved by creating enabling business environment such that every actors and players work in a fair manner. This can be achieved by transparency in price and quality grade. With development achieved in Information and Communication Technology (ICT), having a good and reliable flow of such information is not difficult. In addition to information flow, the availability and quality of infrastructure to support flow of goods from farm-gate to end-user is of reasonably important.

This study quantitatively and qualitatively described HIV risk behaviors among Vietnamese female sex workers (FSWs) who work at three distinct venues in Ho Chi Minh City: street, massage parlors, and bars/clubs. Although 35% of the participants had never been tested for HIV, 18% of street and 7% of bar/club FSWs reported being positive. Almost all massage parlor FSWs had never used a condom for oral sex. Inconsistent condom use for vaginal sex with customers was more prevalent among bar/club FSWs (85%) than massage parlor (72%) and street FSWs (68%). Many participants reported difficulties in negotiating condom use with customers because of economic pressure, maintaining relationships, and lack of bargaining power. Bar/club FSWs revealed a difficult situation where drinking is part of their work. Thirty percent of street FSWs had injected drugs and reported addiction to heroin in relation to their helpless condition as FSWs. Street FSWs had the lowest levels of self-esteem and norms toward practicing safe sex and the highest levels of economic pressure. This study recommends future HIV prevention programs for FSWs in Vietnam that target their specific risk behaviors and work environments.

La situación económica: social determinants of contraceptive use in rural Honduras.

Contraceptive use is an important determinant of unintended pregnancy, but little is known about the social and structural factors that determine women's contraceptive use in rural Honduras. In this study, we aim to characterise the individual and social determinants of contraceptive use among women in rural Honduras. In 2011 and 2012, we conducted 14 interviews and 2 focus groups with women 18 years and older. In our analysis, we created a family-planning narrative for each participant and coded transcripts around key emergent themes related to these determinants. We found that social determinants--including poverty, gender dynamics and availability of family-planning methods--had a strong influence on contraceptive use among women in our sample. Study participants stated that they were faced with a difficult economic situation compounded by rising prices of basic goods and diminishing job opportunities. Paradoxically, at the same time that the economic situation led women to seek contraception, it also contributed to the structural barriers that limited their ability to obtain their method of choice and maintain continuous contraceptive use. Our findings suggest the need for multi-level efforts to create an enabling and sustainable environment for family planning among women in rural Honduras.

Nurse executives' values and leadership behaviors. Conflict or coexistence?

2002-01-01

Nurse leaders struggle to provide for the delivery of humanistic and holistic healthcare that is consistent with nursing values in a changing economic environment. There is concern that nurse executives find it increasingly difficult to reconcile the differences between organizational economics and their personal and professional identities. The purpose of this study was to examine the relationship between nurse executives' perceived personal and organizational value congruence and their leadership behaviors (i.e., transformational, transactional, and laissez-faire). Four hundred and eleven nurse executives employed by American Hospital Association hospitals located east of the Mississippi participated in the study. Findings provide insight into the values held by nurse executives, personal and organizational value congruence and conflict perceived by nurse executives, and the leadership behaviors used by nurse executives. For example, the findings indicate there is a moderate degree of value congruence between nurse executives' personal and organizational values; however, the degree to which specific values are important is significantly different. Nurse executives report that they most often engage in transformational leadership behaviors, but there was no relationship between their leadership behavior and the degree of personal and organizational value congruence. Implications for nursing and nursing research are discussed.

In full swing? How do pendulum migrant labourers in Vietnam adjust their sexual perspectives to their rural-urban lives?

Nguyen, Huong Ngoc; Hardesty, Melissa; Hong, Khuat Thu

2011-11-01

Having emerged only recently due to fast urbanisation and globalisation, pendulum migrant labourers in Vietnam are economically, culturally and socially difficult to locate - though they are estimated to number in their millions. Defined by their frequent migration between village and city, pendulum migrant labourers occupy an extended period of liminality. Are they traditional villagers or liberal city people when it comes to sex? Does city life radically change their views on sexuality? Starting with the premise that living environments play a key role in structuring the practical and symbolic realities of sex, this paper explores how extended periods of circular migration between the village and city - living environments that differ markedly in terms of socioeconomic and cultural conditions - affect the sexual views and perspectives of Vietnamese pendulum migrant labourers. Analysis from in-depth interviews with 23 married pendulum migrant labourers revealed that even though they had been living the pendulum life for several years, they continued to identify themselves, sexually, as traditional villagers. Among labourers the link between sexuality and living environment was a matter of pragmatism - matching 'suitable' sexual behaviour to social, even if imagined, location - and of privilege or 'leagues' - matching behaviour and comportment to social pedigree.

2012-05-01

Healthcare systems across the globe are currently challenged by aging populations, increases in chronic diseases and the difficult task of managing a healthcare budget. In this health economic climate, personalized medicine promises not only an improvement in healthcare delivery but also the possibility of more cost-effective therapies. It is important to remember, however, that personalized medicine has the potential to both increase and decrease costs. Each targeted therapy must be evaluated individually. However, standard clinical trial design is not suitable for personalized therapies. Therefore, both scientists and regulatory authorities will need to accept innovative study designs in order to validate personalized therapies. Hence correct economic evaluations are difficult to carry out due to lack of clear clinical evidence, longitudinal accounting and experience with patient/clinician behavior in the context of personalized medicine. In terms of reimbursement, payers, pharmaceutical companies and companion diagnostic manufacturers will also need to explore creative risk-sharing concepts. Germany is no exception to the challenges that face personalized medicine and for personalized medicine to really become the future of medicine many health economic challenges first need to be overcome. The health economic implications of personalized medicine remain unclear but it is certain that the expansion of targeted therapies in current healthcare systems will create a host of challenges.

2012-01-01

Background Quality of life (QoL) is an important health index for the elderly, necessary for assessing interventions, and prioritising medical and social care needs. As the ageing population in Vietnam continues to increase, understanding important dimensions of QoL for the elderly is essential. There is a paucity of research in this area, however, and the available literature focuses on functional capacities. The purpose of this article is to explore perceptions on the dimensions of QoL among the elderly in Vietnam, to use these perceptions to broaden the concept, and to explore similarities and differences between those living in urban compared to rural areas. Method Qualitative methods included in-depth interviews (IDI) with experts in ageing and elderly persons, as well as focus group discussions (FGDs) in three communes in Hai Duong province. IDIs and FGDs were recorded and transcribed. NVivo software was used to analyse the data. Results Thematic analysis identified physical, psychological, social, environmental, religious, and economic as important dimensions of QoL. For elderly participants in both urban and rural areas, physical health, social relations, finances and economics, the physical and social environment, and psychological health were reported as important. Rural participants also identified religious practice as an important dimension of QoL. In terms of relationships, the elderly in urban areas prioritised those with their children, while the elderly in rural areas focussed their concerns on community relationships and economic conditions. Conclusion Isolating individual factors that contribute to QoL among the elderly is difficult given the inter-relations and rich cross-linkages between themes. Elderly participants in urban and rural areas broadly shared perspectives on the themes identified, in particular social relationships, but their experiences diverged around issues surrounding finances and economics, their respective physical and social environments, and the contribution of religious practice. The study findings may help provide guidance for the development of a socially and culturally relevant instrument for measuring QoL among the elderly in Vietnam. The results will also be useful for developing policies and interventions that are responsive to the needs of the elderly, and reflect the themes perceived to be important. PMID:23273251

Economic development, accompanying with environmental damage and energy depletion, becomes essential nowadays. There is a complicated and comprehensive interaction between economics, environment and energy. Understanding the operating mechanism of Energy-Environment-Economy model (3E) and its key factors is the inherent part in dealing with the issue. In this paper, we combine System Dynamics model and Geographic Information System to analyze the energy-environment-economy (3E) system both temporally and spatially, which explicitly explore the interaction of economics, energy, and environment and effects of the key influencing factors. Beijing is selected as a case study to verify our SD-GIS model. Alternative scenarios, e.g., current, technology, energy and environment scenarios are explored and compared. Simulation results shows that, current scenario is not sustainable; technology scenario is applicable to economic growth; environment scenario maintains a balanced path of development for long term stability. Policy-making insights are given based on our results and analysis. Copyright © 2018 Elsevier Inc. All rights reserved.

Unpacking socio-economic risks for reading and academic self-concept in primary school: Differential effects and the role of the preschool home learning environment.

Uncertainty remains concerning how children's reading and academic self-concept are related and how these are differentially affected by social disadvantage and home learning environments. To contrast the impacts of early socio-economic risks and preschool home learning environments upon British children's reading abilities and academic self-concept between 7 and 10 years. n = 3,172 British children aged 3-10 years and their families. A secondary analysis of the nationally representative UK EPPE database. Multilevel structural equation modelling calculated the direct, indirect, and total impacts of early socio-economic risks (0-3 years) and preschool home learning environments (3-5 years) upon children's reading ability and academic self-concept between 7 and 10 years. Early socio-economic risk had different effects upon children's reading ability and academic self-concept. Early socio-economic risks affected children's reading at ages 7 and 10 both directly and indirectly via effects upon preschool home learning environments. By contrast, early socio-economic risks had only indirect effects upon children's academic self-concept via less stimulating home learning environments in the preschool period and by limiting reading abilities early on in primary school. Although the impacts of early socio-economic risks are larger and more easily observed upon reading than upon academic self-concept, they can impact both by making it less likely that children will experience enriching home learning environments during the preschool period. This has implications for social policymakers, early educators, and interventionists. Intervening early and improving preschool home learning environments can do more than raise children's reading abilities; secondary benefits may also be achievable upon children's self-concept. © 2017 The British Psychological Society.

economic stability gained from two trends: the spread of constitutional democracy and economic globalization. Two major occurrences, colonialism and the Cold War, prevented the Sub-Saharan states from following these two trends. The disruption in sovereignty caused by colonialism, which was then followed by hastily formed governments during the Cold War, spawned conditions of corruption, scarcity, and violent competition. These conditions make it difficult for African states to achieve lasting stability and advance economically. As a result, any stability gained is often

Decree No. 2012-1116 of 2 October 2012 on medico-economic assignments of the French National Authority for Health (Haute autorité de santé, HAS) significantly alters the conditions for accessing the health products market in France. This paper presents a theoretical framework for interpreting the results of the economic evaluation of health technologies and summarises the facts available in France for developing benchmarks that will be used to interpret incremental cost-effectiveness ratios. This literature review shows that it is difficult to determine a threshold value but it is also difficult to interpret then incremental cost effectiveness ratio (ICER) results without a threshold value. In this context, round table participants favour a pragmatic approach based on "benchmarks" as opposed to a threshold value, based on an interpretative and normative perspective, i.e. benchmarks that can change over time based on feedback. © 2014 Société Française de Pharmacologie et de Thérapeutique.

The intensive care unit (ICU) is a complex system and the economic implications of altering care patterns in the ICU can be difficult to unravel. Few studies have specifically examined the economics of implementing organizational and management changes or acknowledged the many competing economic interests of patient, hospital,payer, and society. With continuously increasing healthcare costs,there is a great need for more studies focused on the optimal organization of the ICU. These studies should not focus solely on reductions in ICU length of stay but should strive to measure the true costs of care within a given healthcare system.

2014-10-01

With the development of the society and economy, the contradictions among population, resources and environment are increasingly worse. As a result, the capacity of resources and environment becomes one of the focal issues for many countries and regions. Through investigating and analyzing the present situation and the existing problems of resources and environment in Poyang Lake Eco-economic Zone, seven factors were chosen as the evaluation criterion layer, namely, land resources, water resources, biological resources, mineral resources, ecological-geological environment, water environment and atmospheric environment. Based on the single factor evaluation results and with the county as the evaluation unit, the comprehensive capacity of resources and environment was evaluated by using the state space method in Poyang Lake Eco-economic Zone. The results showed that it boasted abundant biological resources, quality atmosphere and water environment, and relatively stable geological environment, while restricted by land resource, water resource and mineral resource. Currently, although the comprehensive capacity of the resources and environments in Poyang Lake Eco-economic Zone was not overloaded as a whole, it has been the case in some counties/districts. State space model, with clear indication and high accuracy, could serve as another approach to evaluating comprehensive capacity of regional resources and environment.

BROWN, ROBYN LEWIS; RICHMAN, JUDITH A.; ROSPENDA, KATHLEEN M.

2015-01-01

This study examined processes linking economic stressors, somatic complaints, and two alcohol-related outcomes (past-month drinking and problematic drinking). Structural equation models of data from a national survey revealed that somatic complaints partly explain the association between economic stressors and problematic drinking. The associations of both economic stressors and somatic complaints with problematic drinking were significantly greater for men than women. However, the association between economic stressors and somatic complaints was greater for women. These findings clarify the circumstances in which gender matters most for the associations among economy-related stressors, somatic complaints, and drinking. They highlight the significance of difficult economic circumstances for physical health and, in turn, problematic drinking – particularly among men. PMID:25310370

Genetic and environmental influences on temperament in the first year of life: the Puerto Rico Infant Twin Study (PRINTS).

2005-08-01

Three dimensions of temperament -- difficult temperament, unadaptablility and unsociability -- were assessed in the first year of life by maternal interview in twins born in Puerto Rico during 2001 and 2002. Eight hundred and sixty-five eligible mothers (80%) were traced and interviewed. Model-fitting results showed that additive genetic factors and the individual specific environment contributed to variation in all three dimensions. In addition, the pattern of variances and correlations suggested that sibling contrast effects influence ratings of difficult temperament. Moderate effects of the shared environment contributed to ratings of adaptability and sociability. There was a significant genetic correlation between difficult temperament and unadaptability. Genetic and environmental effects do not differ significantly between boys and girls. The study is the first population-based study of Puerto Rican twins and one of few to attempt the assessment of behavior in the first year. Preliminary results for difficult temperament and sociability were consistent with those in other populations and ages. In contrast, a significant effect of the shared environment on the temperamental trait of unadaptability has not been reported previously.

Seasonality and dietary requirements: will eating seasonal food contribute to health and environmental sustainability?

PubMed

Macdiarmid, Jennie I

2014-08-01

Eating more seasonal food is one proposal for moving towards more sustainable consumption patterns, based on the assumption that it could reduce the environmental impact of the diet. The aim of the present paper is to consider the implications of eating seasonal food on the different elements of sustainability (i.e. health, economics, society), not just the environment. Seasonality can be defined as either globally seasonal (i.e. produced in the natural production season but consumed anywhere in the world) or locally seasonal (i.e. produced in the natural production season and consumed within the same climatic zone). The environmental, health, economic and societal impact varies by the definition used. Global seasonality has the nutritional benefit of providing a more varied and consistent supply of fresh produce year round, but this increases demand for foods that in turn can have a high environmental cost in the country of production (e.g. water stress, land use change with loss of biodiversity). Greenhouse gas emissions of globally seasonal food are not necessarily higher than food produced locally as it depends more on the production system used than transportation. Eating more seasonal food, however, is only one element of a sustainable diet and should not overshadow some of the potentially more difficult dietary behaviours to change that could have greater environmental and health benefits (e.g. reducing overconsumption or meat consumption). For future guidelines for sustainable diets to be realistic they will need to take into account modern lifestyles, cultural and social expectations in the current food environment.

How useful are skills acquired at adult non-formal education and training centres for finding employment in South Africa?

NASA Astrophysics Data System (ADS)

Mayombe, Celestin; Lombard, Antoinette

2015-10-01

Non-formal adult education and training (NFET) in South Africa is instrumental in breaking the high level of poverty and decreasing the social inequality the country continues to face as a post-apartheid democracy. Public and private NFET centres in South Africa aim to meet the training needs of adults who have been deprived of formal education with courses which foster access to opportunities for skills acquisition and employment and bring about social and economic inclusion. However, many adults who were facing long-term unemployment due to a lack of marketable skills remain unemployed after completing NFET programmes. This paper reports on a study which investigated what constitutes favourable conditions ("internal enabling environments") for skills acquisition inside NFET centres leading to employment and how they can be improved to contribute to coordinated efforts of increasing NFET graduates' paid and/or self-employment capacities. The authors found that centres focusing on activities suitable for self-employment during training were more likely to create internal enabling environments for skills acquisition and income generation than centres offering courses designed for entering paid employment. The authors conclude that there appears to be a significant correlation between NFET centres' training programme objectives, financial resources, trainee selection criteria, the process of training needs assessment, and skills acquisition for successful employment outcomes of NFET graduates. Without these internal enabling factors, adult trainees are likely to continue finding it difficult to integrate into the labour market or participate in economic activities and hence break the cycle of poverty and social exclusion.

2017-04-01

Since the reform and opening up, the socio-economic pressures have led to increasingly tight resource constraints and serious environmental pollution problems in China, especially for typical ecological regions. The ecological system is under a severe situation and resource and environmental issues have become the bottleneck of economic development. Taking the Chen Barag Banner which has been considered as typical ecological regions as an example, the evaluation indexes system of resources and environment carrying capacity was divided into three subsystems: natural driving force, socio-economic pressure and ecological health. On the basis of the indexes system and related data of Chen Barag Banner in 2014, the evaluation model of resources and environment carrying capacity based on spring model were proposed to analysis the state of resources and environment carrying, and an assessment of influence of socio-economic pressure on the resources and environment system has been conducted by using the discretization method of socio-economic data. The results showed that:(1) The resources and environment system of Baorixile Town, Huhenuoer Town and Bayankuren Town were overloaded among the ten towns, the values of Resources and Environment Carrying Capacity(RECC) / Resources and Environment Carrying State(RECS) were 9.86, 1.37 and 1.22, respectively;(2) The natural driving force index of Xiwuzhuer Town, Hadatu state-owned farm and Bayanhada Town were 0.40, 0.42 and 0.43, respectively, which were lower than others and indicated that the natural conditions in these areas were better than others;(3) The situation of ecological environment Ewenke Town, Hadatu state-owned farm and Tenihe state-owned farm were the best due to the result that the ecological health index of these three towns were 0.21, 0.22 and 0.26, respectively, which were lower than others;(4) The influence of socio-economic pressure on the system of resources and environment in Baorixile Town, Hadatu state-owned farm and Tenihe state-owned farm were the heaviest, the values of social and economic pressure index were 0.61, 0.32 and 0.30 respectively;(5) The discretization result of socio-economic pressure in the scale of 10km*10km space unit was helpful to understand the trend of socio-economic pressure within the township, which couldn't be learned from the result based on the scale of the township;(6) The main factors that affected the environmental carrying capacity of Chen Barag Banner were soil moisture content and per capita water resources;(7) Consumption of water resources and land resources, environmental pollution resulted from the production of agriculture and animal husbandry were the main causes of socio-economic pressures.

Decision Making: from Neuroscience to Psychiatry

Lee, Daeyeol

2013-01-01

Adaptive behaviors increase the likelihood of survival and reproduction and improve the quality of life. However, it is often difficult to identify optimal behaviors in real life due to the complexity of the decision maker’s environment and social dynamics. As a result, although many different brain areas and circuits are involved in decision making, evolutionary and learning solutions adopted by individual decision makers sometimes produce suboptimal outcomes. Although these problems are exacerbated in numerous neurological and psychiatric disorders, their underlying neurobiological causes remain incompletely understood. In this review, theoretical frameworks in economics and machine learning and their applications in recent behavioral and neurobiological studies are summarized. Examples of such applications in clinical domains are also discussed for substance abuse, Parkinson’s disease, attention-deficit/hyperactivity disorder, schizophrenia, mood disorders, and autism. Findings from these studies have begun to lay the foundations necessary to improve diagnostics and treatment for various neurological and psychiatric disorders. PMID:23622061

2012-07-01

Bushfires are becoming one of the environmental challenges confronting Ghana and increasingly it has become difficult for the Government to control it because this activity is deeply rooted in the socio-cultural and economic systems of the people. The effects of bushfire on rural livelihoods and on the ecosystem in Ghana are extensive and damaging. Bushfires have accelerated environmental degradation especially in the fragile savannah ecosystem, yet there is very little in the form of public education, published data and information concerning the frequency, intensity, duration and effects of bushfire on the environment and human welfare in Ghana. The study did a change detection of biomass cover using pre and post fire normalized burnt ratio of Landsat TM+ imageries of 2002 and 2003 to determine fire severity on vegetative cover. The socio-economic impact of this disaster was collected using social survey approaches such as interviews and focus group meetings. Some of the consequences of the bushfire include the burning of food stuffs, houses as well as domestic animals. The environmental impacts of these bushfires have been very devastating and these involve the lost of biodiversity (plants and animals) and the depletion of organic matter of the soil thus impoverishing the soils. The research found out that, the continuous prevalence of this activity was due to the laxity in the implementation of bye-laws regulating bushfire burning due to the lack of personnel and logistics to state agencies in the District to combat the problem.

Using ecosystem services to represent the environment in hydro-economic models

2016-07-01

Demand for water is expected to grow in line with global human population growth, but opportunities to augment supply are limited in many places due to resource limits and expected impacts of climate change. Hydro-economic models are often used to evaluate water resources management options, commonly with a goal of understanding how to maximise water use value and reduce conflicts among competing uses. The environment is now an important factor in decision making, which has resulted in its inclusion in hydro-economic models. We reviewed 95 studies applying hydro-economic models, and documented how the environment is represented in them and the methods they use to value environmental costs and benefits. We also sought out key gaps and inconsistencies in the treatment of the environment in hydro-economic models. We found that representation of environmental values of water is patchy in most applications, and there should be systematic consideration of the scope of environmental values to include and how they should be valued. We argue that the ecosystem services framework offers a systematic approach to identify the full range of environmental costs and benefits. The main challenges to more holistic representation of the environment in hydro-economic models are the current limits to understanding of ecological functions which relate physical, ecological and economic values and critical environmental thresholds; and the treatment of uncertainty.

We investigated whether associations of neighborhood social environment attributes and physical activity differed among 12 countries and levels of economic development using World Bank classification (low/lower-middle-, upper-middle- and high- income countries) among 9-11 year old children (N=6161) from the International Study of Childhood Obesity, Lifestyle, and the Environment (ISCOLE). Collective efficacy and perceived crime were obtained via parental/guardian report. Moderate-to-vigorous physical activity (MVPA) was assessed with waist-worn Actigraph accelerometers. Neighborhood environment by country interactions were tested using multi-level statistical models, adjusted for covariates. Effect estimates were reported by country and pooled estimates calculated across World Bank classifications for economic development using meta-analyses and forest plots. Associations between social environment attributes and MVPA varied among countries and levels of economic development. Associations were more consistent and in the hypothesized directions among countries with higher levels economic development, but less so among countries with lower levels of economic development.

Although some important features of genetically modified (GM) crops such as insect resistance, herbicide tolerance, and drought tolerance might seem to be beneficial for small-scale farmers, the adoption of GM technology by smallholders is still slight. Identifying pros and cons of using this technology is important to understand the impacts of GM crops on these farmers. This article reviews the main opportunities and challenges of GM crops for small-scale farmers in developing countries. The most significant advantages of GM crops include being independent to farm size, environment protection, improvement of occupational health issues, and the potential of bio-fortified crops to reduce malnutrition. Challenges faced by small-scale farmers for adoption of GM crops comprise availability and accessibility of GM crop seeds, seed dissemination and price, and the lack of adequate information. In addition, R&D and production costs in using GM crops make it difficult for these farmers to adopt the use of these crops. Moreover, intellectual property right regulations may deprive resource poor farmers from the advantages of GM technology. Finally, concerns on socio-economic and environment safety issues are also addressed in this paper.

Software reengineering

Fridge, Ernest M., III

1991-01-01

Programs in use today generally have all of the function and information processing capabilities required to do their specified job. However, older programs usually use obsolete technology, are not integrated properly with other programs, and are difficult to maintain. Reengineering is becoming a prominent discipline as organizations try to move their systems to more modern and maintainable technologies. The Johnson Space Center (JSC) Software Technology Branch (STB) is researching and developing a system to support reengineering older FORTRAN programs into more maintainable forms that can also be more readily translated to a modern languages such as FORTRAN 8x, Ada, or C. This activity has led to the development of maintenance strategies for design recovery and reengineering. These strategies include a set of standards, methodologies, and the concepts for a software environment to support design recovery and reengineering. A brief description of the problem being addressed and the approach that is being taken by the STB toward providing an economic solution to the problem is provided. A statement of the maintenance problems, the benefits and drawbacks of three alternative solutions, and a brief history of the STB experience in software reengineering are followed by the STB new FORTRAN standards, methodology, and the concepts for a software environment.

Is the objective food environment associated with perceptions of the food environment?

Williams, Lauren K; Thornton, Lukar; Ball, Kylie; Crawford, David

2012-02-01

The present study examined whether objective measures of the food environment are associated with perceptions of the food environment and whether this relationship varies by socio-economic disadvantage. The study is a cross-sectional analysis of self-report surveys and objective environment data. Women reported their perceptions on the nutrition environment. Participants' homes and food stores were geocoded to measure the objective community nutrition environment. Data on the average price and variety of fruit and vegetables were used to measure the objective consumer nutrition environment. The study was conducted in Melbourne, Australia, in 2003-2004. Data presented are from a sample of 1393 women aged 18-65 years. Overall the match between the perceived and objective environment was poor, underscoring the limitations in using perceptions of the environment as a proxy for the objective environment. Socio-economic disadvantage had limited impact on the relationship between perceived and objective nutrition environment. Further research is needed to understand the determinants of perceptions of the nutrition environment to enhance our understanding of the role of perceptions in nutrition choices and drivers of socio-economic inequalities in nutrition.

Geologic Controls on the Growth of Petroleum Reserves

2008-01-01

The geologic characteristics of selected siliciclastic (largely sandstone) and carbonate (limestone and dolomite) reservoirs in North America (largely the continental United States) were investigated to improve our understanding of the role of geology in the growth of petroleum reserves. Reservoirs studied were deposited in (1) eolian environments (Jurassic Norphlet Formation of the Gulf Coast and Pennsylvanian-Permian Minnelusa Formation of the Powder River Basin), (2) interconnected fluvial, deltaic, and shallow marine environments (Oligocene Frio Formation of the Gulf Coast and the Pennsylvanian Morrow Formation of the Anadarko and Denver Basins), (3) deeper marine environments (Mississippian Barnett Shale of the Fort Worth Basin and Devonian-Mississippian Bakken Formation of the Williston Basin), (4) marine carbonate environments (Ordovician Ellenburger Group of the Permian Basin and Jurassic Smackover Formation of the Gulf of Mexico Basin), (5) a submarine fan environment (Permian Spraberry Formation of the Midland Basin), and (6) a fluvial environment (Paleocene-Eocene Wasatch Formation of the Uinta-Piceance Basin). The connection between an oil reservoir's production history and geology was also evaluated by studying production histories of wells in disparate reservoir categories and wells in a single formation containing two reservoir categories. This effort was undertaken to determine, in general, if different reservoir production heterogeneities could be quantified on the basis of gross geologic differences. It appears that reserve growth in existing fields is most predictable for those in which reservoir heterogeneity is low and thus production differs little between wells, probably owing to relatively homogeneous fluid flow. In fields in which reservoirs are highly heterogeneous, prediction of future growth from infill drilling is notably more difficult. In any case, success at linking heterogeneity to reserve growth depends on factors in addition to geology, such as engineering and technological advances and political or cultural or economic influences.

Neighborhood-level characteristics such as economic hardship and the retail food environment are assumed to be correlated and to influence consumers' dietary behavior and health status, but few studies have investigated these different relationships comprehensively in a single study. This work aims to investigate the association between neighborhood-level economic hardship, the retail food environment, fast food consumption, and obesity prevalence. Linking data from the population-based Survey of the Health of Wisconsin (SHOW, n = 1,570, 2008-10) and a commercially available business database, the Wisconsin Retail Food Environment Index (WRFEI) was defined as the mean distance from each participating household to the three closest supermarkets divided by the mean distance to the three closest convenience stores or fast food restaurants. Based on US census data, neighborhood-level economic hardship was defined by the Economic Hardship Index (EHI). Relationships were analyzed using multivariate linear and logistic regression models. SHOW residents living in neighborhoods with the highest economic hardship faced a less favorable retail food environment (WRFEI = 2.53) than residents from neighborhoods with the lowest economic hardship (WRFEI = 1.77; p-trend < 0.01). We found no consistent or significant associations between the WRFEI and obesity and only a weak borderline-significant association between access to fast food restaurants and self-reported fast food consumption (≥ 2 times/week, OR = 0.59-0.62, p = 0.05-0.09) in urban residents. Participants reporting higher frequency of fast food consumption (≥ 2 times vs. <2 times per week) were more likely to be obese (OR = 1.35, p = 0.06). This study indicates that neighborhood-level economic hardship is associated with an unfavorable retail food environment. However inconsistent or non-significant relationships between the retail food environment, fast food consumption, and obesity were observed. More research is needed to enhance methodological approaches to assess the retail food environment and to understand the complex relationship between neighborhood characteristics, health behaviors, and health outcomes.

[Progress in transgenic fish techniques and application].

Transgenic technique provides a new way for fish breeding. Stable lines of growth hormone gene transfer carps, salmon and tilapia, as well as fluorescence protein gene transfer zebra fish and white cloud mountain minnow have been produced. The fast growth characteristic of GH gene transgenic fish will be of great importance to promote aquaculture production and economic efficiency. This paper summarized the progress in transgenic fish research and ecological assessments. Microinjection is still the most common used method, but often resulted in multi-site and multi-copies integration. Co-injection of transposon or meganuclease will greatly improve the efficiency of gene transfer and integration. "All fish" gene or "auto gene" should be considered to produce transgenic fish in order to eliminate misgiving on food safety and to benefit expression of the transferred gene. Environmental risk is the biggest obstacle for transgenic fish to be commercially applied. Data indicates that transgenic fish have inferior fitness compared with the traditional domestic fish. However, be-cause of the genotype-by-environment effects, it is difficult to extrapolate simple phenotypes to the complex ecological interactions that occur in nature based on the ecological consequences of the transgenic fish determined in the laboratory. It is critical to establish highly naturalized environments for acquiring reliable data that can be used to evaluate the environ-mental risk. Efficacious physical and biological containment strategies remain to be crucial approaches to ensure the safe application of transgenic fish technology.

IgE-blocking therapy for difficult-to-treat asthma: a brief review.

To review the characteristics of difficult-to-treat asthma and describe patients who may benefit from therapy with the recently approved humanized monoclonal antiimmunoglobulin E (IgE) antibody, omalizumab. Up to 20 percent of patients have difficult-to-treat asthma. These patients consume a disproportionate share of asthma care resources. Clinical and economic outcomes can be improved via improved self-management, increased adherence to prescribed therapy, and better compliance to national asthma treatment guidelines. These patients also may benefit from therapies that directly target mechanisms responsible for persistent airway inflammation and elicit favorable clinical responses. Effective asthma control remains difficult in a small cohort of patients with persistent, severe airway inflammation. Management strategies that improve asthma control and reduce exacerbations can improve clinical outcomes and minimize health care resource utilization.

Health, nutrition and prosperity: a microeconomic perspective.

PubMed Central

Thomas, Duncan; Frankenberg, Elizabeth

2002-01-01

A positive correlation between health and economic prosperity has been widely documented, but the extent to which this reflects a causal effect of health on economic outcomes is very controversial. Two classes of evidence are examined. First, carefully designed random assignment studies in the laboratory and field provide compelling evidence that nutritional deficiency - particularly iron deficiency - reduces work capacity and, in some cases, work output. Confidence in these results is bolstered by a good understanding of the underlying biological mechanisms. Some random assignment studies indicate an improved yield from health services in the labour market. Second, observational studies suggest that general markers of nutritional status, such as height and body mass index (BMI), are significant predictors of economic success although their interpretation is confounded by the fact that they reflect influences from early childhood and family background. Energy intake and possibly the quality of the diet have also been found to be predictive of economic success in observational studies. However, the identification of causal pathways in these studies is difficult and involves statistical assumptions about unobserved heterogeneity that are difficult to test. Illustrations using survey data demonstrate the practical importance of this concern. Furthermore, failure to take into account the dynamic interplay between changes in health and economic status has led to limited progress being reported in the literature. A broadening of random assignment studies to measure the effects of an intervention on economic prosperity, investment in population-based longitudinal socioeconomic surveys, and application of emerging technologies for a better measure of health in these surveys will yield very high returns in improving our understanding of how health influences economic prosperity.

Yoon, Hyun-Sook

2013-06-01

Population aging in Korea is projected to be the most rapid among Organisation for Economic Co-operation and Development (OECD) countries between 2000 and 2050. However, social spending in Korea remains low, reflecting Korea's relatively young population, limited health and long-term care insurance coverage, and immaturity of its pension system. As these factors evolve in coming years, social spending in Korea is likely to rise toward the OECD average. Sustaining economic growth requires policies to mitigate the impact of rapid population aging by providing social protection for the elderly population. Korea confronts difficult challenges in balancing economic growth and social protection for the elderly population, whereas also ensuring efficiency in social spending.

To support European Union water policy making and policy monitoring, a hydro-economic modelling environment has been developed to assess optimum combinations of water retention measures, water savings measures, and nutrient reduction measures for continental Europe. This modelling environment consists of linking the agricultural CAPRI model, the LUMP land use model, the LISFLOOD water quantity model, the EPIC water quality model, the LISQUAL combined water quantity, quality and hydro-economic model, and a multi-criteria optimisation routine. With this modelling environment, river basin scale simulations are carried out to assess the effects of water-retention measures, water-saving measures, and nutrient-reduction measures on several hydro-chemical indicators, such as the Water Exploitation Index (WEI), Nitrate and Phosphate concentrations in rivers, the 50-year return period river discharge as an indicator for flooding, and economic losses due to water scarcity for the agricultural sector, the manufacturing-industry sector, the energy-production sector and the domestic sector, as well as the economic loss due to flood damage. Recently, this model environment is being extended with a groundwater model to evaluate the effects of measures on the average groundwater table and available resources. Also, water allocation rules are addressed, while having environmental flow included as a minimum requirement for the environment. Economic functions are currently being updated as well. Recent development and examples will be shown and discussed, as well as open challenges.

Within-species patterns challenge our understanding of the causes and consequences of trait variation with implications for trait-based models

Functional traits could facilitate ecological prediction by provide scale-free tools for modeling ecosystem function. Yet much of their utility lies in three key assumptions: 1) that global patterns of trait covariation are the result of universal trade-offs independent of taxonomic scale, so empirical trait-trait relationships can be used to constrain vegetation models 2) that traits respond predictably to environmental gradients and can therefore be reliably quantified to parameterize models and 3) that well sampled traits influence productivity. We use an extensive dataset of within-species leaf trait variation in North American conifers combined with global leaf trait datasets to test these assumptions. We examine traits central to the `leaf economics spectrum', and quantify patterns of trait variation at multiple taxonomic scales. We also test whether site environment explains geographic trait variation within conifers, and ask whether foliar traits explain geographic variation in relative growth rates. We find that most leaf traits vary primarily between rather than within species globally, but that a large fraction of within-PFT trait variation is within-species. We also find that some leaf economics spectrum relationships differ in sign within versus between species, particularly the relationship between leaf lifespan and LMA. In conifers, we find weak and inconsistent relationships between site environment and leaf traits, making it difficult capture within-species leaf trait variation for regional model parameterization. Finally, we find limited relationships between tree relative growth rate and any foliar trait other than leaf lifespan, with leaf traits jointly explaining 42% of within-species growth variation but environmental factors explaining 77% of variation. We suggest that additional traits, particularly whole plant allometry/allocation traits may be better than leaf traits for improving vegetation model performance at smaller taxonomic and spatial scales.

Epidemiological surveillance methods for vector-borne diseases.

PubMed

Thompson, P N; Etter, E

2015-04-01

Compared with many other diseases, the ever-increasing threat of vector-borne diseases (VBDs) represents a great challenge to public and animal health managers. Complex life cycles, changing distribution ranges, a variety of potential vectors and hosts, and the possible role of reservoirs make surveillance for VBDs a grave concern in a changing environment with increasing economic constraints. Surveillance activities may have various specific objectives and may focus on clinical disease, pathogens, vectors, hosts and/or reservoirs, but ultimately such activities should improve our ability to predict, prevent and/or control the diseases concerned. This paper briefly reviews existing and newly developed tools for the surveillance of VBDs. A range of examples, by no means exhaustive, illustrates that VBD surveillance usually involves a combination of methods to achieve its aims, and is best accomplished when these techniques are adapted to the specific environment and constraints of the region. More so than any other diseases, VBDs respect no administrative boundaries; in addition, animal, human and commodity movements are increasing dramatically, with illegal or unknown movements difficult to quantify. Vector-borne disease surveillance therefore becomes a serious issue for local and national organisations and is being conducted more and more at the regional and international level through multidisciplinary networks. With economic and logistical constraints, tools for optimising and evaluating the performance of surveillance systems are essential and examples of recent developments in this area are included. The continuous development of mapping, analytical and modelling tools provides us with an enhanced ability to interpret, visualise and communicate surveillance results. This review also demonstrates the importance of the link between surveillance and research, with interactions and benefits in both directions.

Extremophiles in Household Water Heaters

A significant fraction of Earth's microbial diversity comes from species living in extreme environments, but natural extreme environments can be difficult to access. Manmade systems like household water heaters serve as an effective proxy for thermophilic environments that are otherwise difficult to sample directly. As such, we are investigating the biogeography, taxonomic distribution, and evolution of thermophiles growing in domestic water heaters. Citizen scientists collected hot tap water culture- and filter- samples from 101 homes across the United States. We recovered a single species of thermophilic heterotroph from culture samples inoculated from water heaters across the United States, Thermus scotoductus. Whole-genome sequencing was conducted to better understand the distribution and evolution of this single species. We have also sequenced hyper-variable regions of the 16S rRNA gene from whole-community filter samples to identify the broad diversity and distribution of microbial cells captured from each water heater. These results shed light on the processes that shape thermophilic populations and genomes at a spatial resolution that is difficult to access in naturally occurring extreme ecosystems.

A genetic analysis of post-weaning feedlot performance and profitability in Bonsmara cattle.

van der Westhuizen, R R; van der Westhuizen, J; Schoeman, S J

2009-02-25

The aim of this study was to identify factors influencing profitability in a feedlot environment and to estimate genetic parameters for and between a feedlot profit function and productive traits measured in growth tests. The heritability estimate of 0.36 for feedlot profitability shows that this trait is genetically inherited and that it can be selected for. The genetic correlations between feedlot profitability and production and efficiency varied from negligible to high. The genetic correlation estimate of -0.92 between feed conversion ratio and feedlot profitability is largely due to the part-whole relationship between these two traits. Consequently, a multiple regression equation was developed to estimate a feed intake value for all performance-tested Bonsmara bulls, which were group fed and whose feed intakes were unknown. These predicted feed intake values enabled the calculation of a post-weaning growth or feedlot profitability value for all tested bulls, even where individual feed intakes were unknown. Subsequently, a feedlot profitability value for each bull was calculated in a favorable economic environment, an average economic environment and in an unfavorable economic environment. The high Pearson and Spearman correlations between the estimate breeding values based on the average economic environment and the other two environments suggested that the average economic environment could be used to calculate estimate breeding values for feedlot profitability. It is therefore not necessary to change the carcass, weaned calf or feed price on a regular basis to allow for possible re-rankings based on estimate breeding values.

2018-01-01

Clostridium difficile infection (CDI) remains a considerable challenge to health care systems worldwide. Although CDI represents a significant burden on healthcare systems in Europe, few studies have attempted to estimate the consumption of resources associated with CDI in Europe. The reported extra costs attributable to CDI vary widely according to the definitions, design, and methodologies used, making comparisons difficult to perform. In this chapter, the economic burden of healthcare facility-associated CDI in Europe will be assessed, as will other less explored areas such as the economic burden of recurrent CDI, community-acquired CDI, pediatric CDI, and CDI in outbreaks.

Protection of mineral deposits - a way towards difficult compromises

NASA Astrophysics Data System (ADS)

Radwanek-Bąk, Barbara; Nieć, Marek

2014-05-01

Mineral deposits are non-renewable natural resources. Their protection and reasonable exploitation are crucial requests resulting from sustainable development principles. Those are also fundamental issues in frame of the intergeneration justice and fairness concept. Protection of mineral resources should be based on interrelated activities: maintaining the possibility of economic use of the identified mineral resources, reduced consumption of mineral resources and ensuring satisfactory results of new prospecting and development of innovative technologies for the mineral resources base. The main problem with guarantee to the use of mineral resources is the accessibility to sites with documented deposits and prospective areas of their occurrence. Often, this contradicts with the interests of residents, planners and needs of the biotic environment protection, thus is often a source of conflicts. Legislative regulations are necessary to mitigate such arguable matters. SWOT analysis carried out with respect to introducing such legal regulations serves to identify the sources of conflicts and difficulties associated with their solution. Consensus reaching is a difficult task, so all decision makers are required to show their mutual understanding and willingness to achieve the goals taking into consideration all benefits for the population (including future generations). Foundations for finding the middle ground are: making the communities aware of their demands on minerals and of indispensable conditions for satisfying these demands; providing complete and accessible information; factual, non-emotional negotiations between decision makers and the public.

Multiagent Flight Control in Dynamic Environments with Cooperative Coevolutionary Algorithms

NASA Technical Reports Server (NTRS)

Colby, Mitchell; Knudson, Matthew D.; Tumer, Kagan

2014-01-01

Dynamic environments in which objectives and environmental features change with respect to time pose a difficult problem with regards to planning optimal paths through these environments. Path planning methods are typically computationally expensive, and are often difficult to implement in real time if system objectives are changed. This computational problem is compounded when multiple agents are present in the system, as the state and action space grows exponentially with the number of agents in the system. In this work, we use cooperative coevolutionary algorithms in order to develop policies which control agent motion in a dynamic multiagent unmanned aerial system environment such that goals and perceptions change, while ensuring safety constraints are not violated. Rather than replanning new paths when the environment changes, we develop a policy which can map the new environmental features to a trajectory for the agent while ensuring safe and reliable operation, while providing 92% of the theoretically optimal performance.

Recruiting and retaining high-quality teachers in rural areas.

PubMed

Monk, David H

2007-01-01

In examining recruitment and retention of teachers in rural areas, David Monk begins by noting the numerous possible characteristics of rural communities--small size, sparse settlement, distance from population concentrations, and an economic reliance on agricultural industries that are increasingly using seasonal and immigrant workers to minimize labor costs. Many, though not all, rural areas, he says, are seriously impoverished. Classes in rural schools are relatively small, and teachers tend to report satisfaction with their work environments and relatively few problems with discipline. But teacher turnover is often high, and hiring can be difficult. Monk observes that rural schools have a below-average share of highly trained teachers. Compensation in rural schools tends to be low, perhaps because of a lower fiscal capacity in rural areas, thus complicating efforts to attract and retain teachers. Several student characteristics, including relatively large shares of students with special needs and with limited English skills and lower shares of students attending college, can also make it difficult to recruit and retain high-quality teachers. Other challenges include meeting the needs of highly mobile children of low-income migrant farm workers. With respect to public policy, Monk asserts a need to focus on a subcategory of what might be called hard-to-staff rural schools rather than to develop a blanket set of policies for all rural schools. In particular, he recommends a focus on such indicators as low teacher qualifications, teaching in fields far removed from the area of training, difficulty in hiring, high turnover, a lack of diversity among teachers in the school, and the presence of migrant farm workers' children. Successful efforts to stimulate economic growth in these areas would be highly beneficial. He also calls attention to the potential for modern telecommunication and computing technologies to offset some of the drawbacks associated with teaching in rural areas.

Brooke is a non-government organisation with working equine welfare programmes across Africa, Asia and Latin America. In 2014, staff from ten country programmes were asked to identify 'no-win' situations (subsequently reframed as 'hard-wins')-where improving equine welfare is proving difficult, expensive and/or marginal-in order to inform strategic decisions on how to approach, manage and mitigate for such situations. The Delphi-type consultation process had three phases. Round 1 posed five questions in the form of a workshop, survey and semi-structured interviews. Round 2 re-presented key themes and sense-checked initial conclusions. Round 3 reviewed the nature and prevalence of hard-win situations at an international meeting of all participants. Reasons given for hard-win situations included: no economic or social benefit from caring for working animals; poor resource availability; lack of empathy for working equids or their owners among wider stakeholders; deep-seated social issues, such as addiction or illegal working; areas with a high animal turnover or migratory human population; lack of community cooperation or cohesion; unsafe areas where welfare interventions cannot be adequately supported. Participants estimated the prevalence of hard-win situations as 40-70% of their work. They suggested some current ways of working that may be contributing to the problem, and opportunities to tackle hard-wins more effectively. Respondents agreed that if equine welfare improvements are to span generations of animals, interventions cannot rely on relatively simple, technical knowledge-transfer strategies and quick-wins alone. Programmes need to be more flexible and iterative and less risk-averse in their approaches to embedding good equine welfare practices in all relevant actors. Consultation recommendations informed development of Brooke's new global strategy, a revised organisational structure and redefinition of roles and responsibilities to streamline ways to approach hard-wins in the complex environments and socio-economic contexts in which working equids are found.

Maintaining the coordinated correlation between ecological environment and economic development is one of the important strategies in the new stage of poverty alleviation and development. Taking 714 poverty-stricken counties in contiguous destitute areas as study areas, this paper designed the ecological vulnerability evaluation indicator system based on the ecological sensitivity-resilience-pressure (SRP) conceptual model, as well as the comprehensive poverty evaluation indicators from the perspective of socioeconomic development, so as to build the coupling model to reveal the coupling between ecological vulnerability and economic poverty. The results showed that Hu-Line could act as a feasible partition label to depict the spatial distribution patterns of ecological vulnerability, economic poverty, as well as their coupling degree in contiguous destitute areas, which should be fully taken into consideration the influence of Hu-Line on the east-west pattern classification of national poverty reduction. In addition, there existed a symbiotic positive correlation between ecological vulnerability and economic poverty, therefore, the strategic significance of ecological and environment protection in poverty-stricken areas should be specifically emphasized to reduce economic poverty by synchronously protecting the ecological environment. Approximately half of the counties involved in the study area were in the coordinated type of recession disorders, where the ecological environment quality and the economic development could not be synchronized.

Background Length of residence in the United States (US), changes in dietary and physical activity behaviors, and economic and social barriers contribute to high childhood obesity rates among children from immigrant families in the US. Brazilians comprise a fast-growing immigrant population group in the US, yet little research has focused on health issues affecting Brazilian children in immigrant families. Understanding sociocultural and environmental influences on parents' beliefs and practices related to child feeding and weight status is essential to altering obesity trends in this group. Methods Qualitative study consisting of five focus groups with a convenience sample of 29 Brazilian immigrant mothers. Results Analyses revealed that the sociocultural and environment transitions faced by Brazilian immigrant mothers' influence their beliefs and practices related to child feeding and weight status. Additionally, acculturation emerged as a factor affecting mothers' feeding practices and their children's eating habits, with mothers preferring Brazilian food environments and that their children preferring American food environments. Mothers viewed themselves as being responsible for promoting and maintaining their children's healthy eating and feeding behaviors, but changes in their social and cultural environments due to immigration and the pressures and demands of raising a family in a new country make this difficult. Conclusions Health promotion interventions to improve healthful eating and feeding practices of Brazilian children in immigrant families must account for social and cultural changes and daily life demands due to immigration as well as potential variation in the levels of acculturation between mothers and their children.

A lack of response of the financial behaviors of biodiversity conservation nonprofits to changing economic conditions.

PubMed

Larson, Eric R; Boyer, Alison G; Armsworth, Paul R

2014-12-01

The effectiveness of conservation organizations is determined in part by how they adapt to changing conditions. Over the previous decade, economic conditions in the United States (US) showed marked variation including a period of rapid growth followed by a major recession. We examine how biodiversity conservation nonprofits in the US responded to these changes through their financial behaviors, focusing on a sample of 90 biodiversity conservation nonprofits and the largest individual organization (The Nature Conservancy; TNC). For the 90 sampled organizations, an analysis of financial ratios derived from tax return data revealed little response to economic conditions. Similarly, more detailed examination of conservation expenditures and land acquisition practices of TNC revealed only one significant relationship with economic conditions: TNC accepted a greater proportion of conservation easements as donated in more difficult economic conditions. Our results suggest that the financial behaviors of US biodiversity conservation nonprofits are unresponsive to economic conditions.

A period of economic recession may be particularly difficult for people with mental health problems as they may be at higher risk of losing their jobs, and more competitive labour markets can also make it more difficult to find a new job. This study assesses unemployment rates among individuals with mental health problems before and during the current economic recession. Using individual and aggregate level data collected from 27 EU countries in the Eurobarometer surveys of 2006 and 2010, we examined changes in unemployment rates over this period among individuals with and without mental health problems. Following the onset of the recession, the gap in unemployment rates between individuals with and without mental health problems significantly widened (odds ratio: 1.12, 95% confidence interval: 1.03, 1.34). This disparity became even greater for males, and individuals with low levels of education. Individuals with mental health problems living in countries with higher levels of stigmatizing attitudes regarding dangerousness of people with mental illness were more vulnerable to unemployment in 2010, but not 2006. Greater agreement that people with mental health problems have themselves to blame, was associated with lower likelihood of unemployment for individuals with and without mental health problems. These findings study suggest that times of economic hardship may intensify social exclusion of people with mental health problems, especially males and individuals with lower education. Interventions to combat economic exclusion and to promote social participation of individuals with mental health problems are even more important during times of economic crisis, and these efforts should target support to the most vulnerable groups.

[Changing economic environment of hospitals: management challenges of the 1990s].

PubMed

Rotstein, Z; Noy, S; Goldman, B; Shani, M

1990-12-16

The modern hospital is an organization which is influenced by the external environment in which it functions. A major relevant area is the economic environment. In recent years the western world has been facing the challenge of rising costs of health care and an increase in their proportion to the gross national product of most countries. Consequently, hospitals as major providers of health care are under pressure from governments and health insurance companies to cut costs and to "produce" more efficiently. Since hospitals worldwide are finding it hard and painful to function in the new environment in which attitudes to hospitals are changing, a potential managerial-economic crisis may be the next phase. How can the hospital adapt to these changes? First, by adopting managerial attitudes and the tools of the business sector. These include: the strategic planning process, hospital operative autonomy, creating medical-economic responsibility centers as departments, cost-accounting for medical procedures, and case-mix budgeting. Management information systems are necessary during the transition. The hospital information system should include functions at the operative level, such as outpatient visits, and admissions and discharges of patients; and also clinical, diagnostic and laboratory procedures related to the patient case-mix. The second level is a management information system which includes salaries of personnel, case-mix budgeting with variance analysis, prices of procedures and epidemiological data. The authors believe that only the managerial approach combining medical and economic disciplines can meet the challenges of the changing modern economic environment.

I maintain that it is unconvincing.

A growing body of evidence shows that community environment plays an important role in individuals' physical activity engagement. However, while attributes of the physical environment are widely investigated, sociocultural, political, and economic aspects of the environment are often neglected. This article helps to fill these knowledge gaps by providing a more comprehensive understanding of multiple dimensions of the community environment relative to physical activity. The purpose of this study was to qualitatively explore how people's experiences and perceptions of their community environments affect their abilities to engage in physical activity. A PhotoVoice method was used to identify barriers to and opportunities for physical activity among residents in four communities in the province of Alberta, Canada, in 2009. After taking pictures, the thirty-five participants shared their perceptions of those opportunities and barriers in their community environments during individual interviews. Using the Analysis Grid for Environments Linked to Obesity (ANGELO) framework, themes emerging from these photo-elicited interviews were organized in four environment types: physical, sociocultural, economic, and political. The data show that themes linked to the physical (56.6%) and sociocultural (31.4%) environments were discussed more frequently than the themes of the economic (5.9%) and political (6.1%) environments. Participants identified nuanced barriers and opportunities for physical activity, which are illustrated by their quotes and photographs. The findings suggest that a myriad of factors from physical, sociocultural, economic, and political environments influence people's abilities to be physically active in their communities. Therefore, adoption of a broad, ecological perspective is needed to address the barriers and build upon the opportunities described by participants to make communities more healthy and active.

Carbon storage by ecosystems is valuable for climate protection. Biodiversity conservation may help increase carbon storage, but the value of this influence has been difficult to assess. We use plant, soil, and ecosystem carbon storage data from two grassland biodiversity experiments to show that greater species richness increases economic value: Increasing species richness from 1 to 10 had twice the economic value of increasing species richness from 1 to 2. The marginal value of each additional species declined as species accumulated, reflecting the nonlinear relationship between species richness and plant biomass production. Our demonstration of the economic value of biodiversity for enhancing carbon storage provides a foundation for assessing the value of biodiversity for decisions about land management. Combining carbon storage with other ecosystem services affected by biodiversity may well enhance the economic arguments for conservation even further. PMID:28435876

Living Arrangements and the Well-being of Single Mothers in Japan

PubMed Central

Raymo, James M.; Zhou, Yanfei

2012-01-01

The goal of this paper is to evaluate the extent to which the well-being of single mothers in Japan is related to coresidence with other adults. Using data from a representative survey of households headed by single mothers, we examine two measures of subjective well-being: perceived economic circumstances and self-rated health. One-fourth of the single mothers surveyed were coresiding with another adult(s) and it is clear that these women fare significantly better than their non-coresiding counterparts on both measures of well-being. Net of several theoretically relevant sociodemographic, family, and employment characteristics, single mothers living with others were significantly less likely to report somewhat difficult/difficult economic circumstances or fair/poor health. Efforts to account for potential endogeneity between well-being and living arrangements suggested that self-rated health, but not subjective economic well-being, is related to selection into coresidence. Single mothers in fair/poor health appear more likely to coreside with others and, accounting for this selection, intergenerational coresidence appears to be very beneficial for self-rated health. We discuss the implications of these findings for processes of stratification in Japan in light of the limited public income support available to single mothers. PMID:23144521

Marginal socio-economic effects of an employer's efforts to improve the work environment.

PubMed

Rezagholi, Mahmoud

2018-01-01

Workplace health promotion (WHP) strongly requires the employer's efforts to improve the psychosocial, ergonomic, and physical environments of the workplace. There are many studies discussing the socio-economic advantage of WHP intervention programmes and thus the internal and external factors motivating employers to implement and integrate such programmes. However, the socio-economic impacts of the employer's multifactorial efforts to improve the work environment need to be adequately assessed. Data were collected from Swedish company Sandvik Materials Technology (SMT) through a work environment survey in April 2014. Different regression equations were analysed to assess marginal effects of the employer's efforts on overall labour effectiveness (OLE), informal work impairments (IWI), lost working hours (LWH), and labour productivity loss (LPL) in terms of money. The employer's multifactorial efforts resulted in increasing OLE, decreasing IWI and illness-related LWH, and cost savings in terms of decreasing LPL. Environmental factors at the workplace are the important determinant factor for OLE, and the latter is where socio-economic impacts of the employer's efforts primarily manifest.

Soft Regulation with Crowd Recommendation: Coordinating Self-Interested Agents in Sociotechnical Systems under Imperfect Information.

PubMed

Luo, Yu; Iyengar, Garud; Venkatasubramanian, Venkat

2016-01-01

Regulating emerging industries is challenging, even controversial at times. Under-regulation can result in safety threats to plant personnel, surrounding communities, and the environment. Over-regulation may hinder innovation, progress, and economic growth. Since one typically has limited understanding of, and experience with, the novel technology in practice, it is difficult to accomplish a properly balanced regulation. In this work, we propose a control and coordination policy called soft regulation that attempts to strike the right balance and create a collective learning environment. In soft regulation mechanism, individual agents can accept, reject, or partially accept the regulator's recommendation. This non-intrusive coordination does not interrupt normal operations. The extent to which an agent accepts the recommendation is mediated by a confidence level (from 0 to 100%). Among all possible recommendation methods, we investigate two in particular: the best recommendation wherein the regulator is completely informed and the crowd recommendation wherein the regulator collects the crowd's average and recommends that value. We show by analysis and simulations that soft regulation with crowd recommendation performs well. It converges to optimum, and is as good as the best recommendation for a wide range of confidence levels. This work sheds a new theoretical perspective on the concept of the wisdom of crowds.

Stress, burnout, and job dissatisfaction in mental health workers.

PubMed

Rössler, Wulf

2012-11-01

As the industrial world has transformed toward a service economy, a particular interest has developed in mental health problems at the workplace. The risk for burnout is significantly increased in certain occupations, notably for health care workers. Beyond the effects of an extensive workload, many working hours, or long night shifts, the medical field has specific stressors. Physicians work in emotionally demanding environments with patients, families, or other medical staff. They must make quick decisions while faced with a quite frequent information overload. All of these stressors have to be weighed against a rapidly changing organizational context within medicine. Today, economics objectives have priority over medical values in health care. In principal, mental health workers should experience similar work stressors and the same contextual factors as health professionals from other medical disciplines. However, several studies have identified stressors that are unique to the psychiatric profession. These challenges range from the stigma of this profession, to particularly demanding relationships with patients and difficult interactions with other mental health professionals as part of multidisciplinary teams to personal threats from violent patients. Other sources of stress are a lack of positive feedback, low pay, and a poor work environment. Finally, patient suicide is a major stressor, upon which a majority of mental health workers report post-traumatic stress symptoms.

Soft Regulation with Crowd Recommendation: Coordinating Self-Interested Agents in Sociotechnical Systems under Imperfect Information

PubMed Central

2016-01-01

Regulating emerging industries is challenging, even controversial at times. Under-regulation can result in safety threats to plant personnel, surrounding communities, and the environment. Over-regulation may hinder innovation, progress, and economic growth. Since one typically has limited understanding of, and experience with, the novel technology in practice, it is difficult to accomplish a properly balanced regulation. In this work, we propose a control and coordination policy called soft regulation that attempts to strike the right balance and create a collective learning environment. In soft regulation mechanism, individual agents can accept, reject, or partially accept the regulator’s recommendation. This non-intrusive coordination does not interrupt normal operations. The extent to which an agent accepts the recommendation is mediated by a confidence level (from 0 to 100%). Among all possible recommendation methods, we investigate two in particular: the best recommendation wherein the regulator is completely informed and the crowd recommendation wherein the regulator collects the crowd’s average and recommends that value. We show by analysis and simulations that soft regulation with crowd recommendation performs well. It converges to optimum, and is as good as the best recommendation for a wide range of confidence levels. This work sheds a new theoretical perspective on the concept of the wisdom of crowds.

Marine luciferases are regularly employed as useful reporter molecules across a range of various applications. However, attempts to transition expression from their native eukaryotic environment into a more economical prokaryotic, i.e. bacterial, expression system often presents several challenges. Specifically, bacterial protein expression inherently lacks chaperone proteins to aid in the folding process, while Escherichia coli presents a reducing cytoplasmic environment in. These conditions contribute to the inhibition of proper folding of cysteine-rich proteins, leading to incorrect tertiary structure and ultimately inactive and potentially insoluble protein. Vargula luciferase (Vluc) is a cysteine-rich marine luciferase that exhibits glow-type bioluminescence through a reaction between its unique native substrate and molecular oxygen. Because most other commonly used bioluminescent proteins exhibit flash-type emission kinetics, this emission characteristic of Vluc is desirable for high-throughput applications where stability of emission is required for the duration of data collection. A truncated form of Vluc that retains considerable bioluminescence activity (55%) compared to the native full-length protein has been reported in the literature. However, expression and purification of this luciferase from bacterial systems has proven difficult. Herein, we demonstrate the expression and purification of a truncated form of Vluc from E. coli. This truncated Vluc (tVluc) was subsequently characterized in terms of both its biophysical and bioluminescence properties. PMID:28108349

Risk-benefit analysis has been implicitly practiced whenever decision-makers are confronted with decisions involving risks to life, health, or to the environment. Various methodologies have been developed to evaluate relevant criteria and to aid in assessing the impacts of alternative projects. Among these have been cost-benefit analysis, which has been widely used for project evaluation. However, in many cases it has been difficult to assign dollar costs to those criteria involving risks and benefits which are not now assigned explicit monetary values in our economic system. Hence, risk-benefit analysis has evolved to become more than merely an extension of cost-benefit analysis,more » and many methods have been applied to examine the trade-offs between risks and benefits. In addition, new scientific and statistical techniques have been developed for assessing current and future risks. The 950 references included in this bibliography are meant to suggest the breadth of those methodologies which have been applied to decisions involving risk.« less

An international perspective on hazardous waste practices.

PubMed

Orloff, Kenneth; Falk, Henry

2003-08-01

In developing countries, public health attention is focused on urgent health problems such as infectious diseases, malnutrition, and infant mortality. As a country develops and gains economic resources, more attention is directed to health concerns related to hazardous chemical wastes. Even if a country has little industry of its own that generates hazardous wastes, the importation of hazardous wastes for recycling or disposal can present health hazards. It is difficult to compare the quantities of hazardous wastes produced in different countries because of differences in how hazardous wastes are defined. In most countries, landfilling is the most common means of hazardous waste disposal, although substantial quantities of hazardous wastes are incinerated in some countries. Hazardous wastes that escape into the environment most often impact the public through air and water contamination. An effective strategy for managing hazardous wastes should encourage waste minimization, recycling, and reuse over disposal. Developing countries are especially in need of low-cost technologies for managing hazardous wastes.

Serpentine soil, which is naturally high in heavy metal content and has low calcium to magnesium ratios, comprises a difficult environment for most plants. An impressive number of species are endemic to serpentine, and a wide range of non-endemic plant taxa have been shown to be locally adapted to these soils. Locating genomic polymorphisms which are differentiated between serpentine and non-serpentine populations would provide candidate loci for serpentine adaptation. We have used the Arabidopsis thaliana tiling array, which has 2.85 million probes throughout the genome, to measure genetic differentiation between populations of Arabidopsis lyrata growing on granitic soils and those growing on serpentinic soils. The significant overrepresentation of genes involved in ion transport and other functions provides a starting point for investigating the molecular basis of adaptation to soil ion content, water retention, and other ecologically and economically important variables. One gene in particular, calcium-exchanger 7, appears to be an excellent candidate gene for adaptation to low CaratioMg ratio in A. lyrata.

Currently, bioresorbable electronic devices are predominantly fabricated by complex and expensive vacuum-based integrated circuit (IC) processes. Here, a low-cost manufacturing approach for bioresorbable conductors on bioresorbable polymer substrates by evaporation-condensation-mediated laser printing and sintering of Zn nanoparticle is reported. Laser sintering of Zn nanoparticles has been technically difficult due to the surface oxide on nanoparticles. To circumvent the surface oxide, a novel approach is discovered to print and sinter Zn nanoparticle facilitated by evaporation-condensation in confined domains. The printing process can be performed on low-temperature substrates in ambient environment allowing easy integration on a roll-to-roll platform for economical manufacturing of bioresorbable electronics. The fabricated Zn conductors show excellent electrical conductivity (≈1.124 × 10 6 S m -1 ), mechanical durability, and water dissolvability. Successful demonstration of strain gauges confirms the potential application in various environmentally friendly sensors and circuits. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

In Tanzania, the international microfinance network FINCA set up shop and began training its first Village Banking Groups in June 1998, disbursing its first loans in July with a grant from the US Agency for International Development. Within 2 months, the program reached 757 low-income women and distributed loans worth US$57,183 using the group support system in which 30-50 neighbors come together to guarantee one another's loans. With the loans from FINCA, entrepreneurs quickly became involved in a range of business activities, from selling tomatoes to starting a hair salon. Located in Mwanza, in the Lake Zone, FINCA Tanzania's clients include many members of the Sukuma tribe. It is noted that in this region there are a few job opportunities in the formal economy. In 1999, FINCA Tanzania reached 3632 clients, exceeding its targets despite a difficult economic environment. In that same year, FINCA partnered with Freedom from Hunger in launching a program that offers some of its members health education and basic business training at Village Banking Group meetings.

I Got Them Dust Bowl Blues: Wind Erosion in the Music of the Southern Great Plains

2017-12-01

This paper deals with the role of wind erosion and blowing dust on the music of the Dust Bowl region, a portion of the southern Great Plains of the United States. A defining characteristic of the region is dust storms, and in the 1930s, severe dust storms created dramatic images that came to symbolize all of the economic, social and environmental hardships suffered by the people during the 1930s. The music of the time, by Woody Guthrie and others, suggested that the region was being destroyed, never to recover. The region was resilient, however, and in recent decades, dust has been depicted in songs either as an adversity to be endured or simply as a normal part of life in the area. It may be that blowing dust has become a defining characteristic of the region because of a somewhat warped sense of pride in living in an often-difficult environment.

The contribution deals with the simplified dynamic analysis of surface grinding machine spindle node. Dynamic analysis is based on the use of the transfer matrix method, which is essentially a matrix form of method of initial parameters. The advantage of the described method, despite the seemingly complex mathematical apparatus, is primarily, that it does not require for solve the problem of costly commercial software using finite element method. All calculations can be made for example in MS Excel, which is advantageous especially in the initial stages of constructing of spindle node for the rapid assessment of the suitability its design. After detailing the entire structure of spindle node is then also necessary to perform the refined dynamic analysis in the environment of FEM, which it requires the necessary skills and experience and it is therefore economically difficult.

Beyond their important economic role in commercial communications, satellites in general are critical infrastructure because of the services they provide. In addition to satellites providing information which facilitates a better understanding of the space environment and improved performance of physics experiments, satellite observations are also used to actively monitor weather, geological processes, agricultural development and the evolution of natural and man-made hazards. Defence agencies depend on satellite services for communication in remote locations, as well as for reconnaissance and intelligence. Both commercial and government users rely on communication satellites to provide communication in the event of a disaster that damages ground-based communication systems, provide news, education and entertainment to remote areas and connect global businesses. The space radiation environment is an hazard to most satellite missions and can lead to extremely difficult operating conditions for all of the equipment travelling in space. Here, we first provide an overview of the main components of space radiation environment, followed by a description of the basic mechanism of the interaction of radiation with matter. This is followed by an introduction to the space radiation hardness assurance problem and the main effects of natural radiation to the microelectronics (total ionizing dose, displacement damage and the single-event effect and a description of how different effects occurring in the space can be tested in on-ground experiments by using particle accelerators and radiation sources. We also discuss standards and the recommended procedures to obtain reliable results.

Referring to the concept of sustainable development, the environment is said to be sustainable if the fulfillment of three pillars of development that is economic, social and ecological or the environment itself. The environment can sustained in the principle of ecology or basic principles of environmental science, when the three environmental components, namely the natural environment, the artificial environment (the built environment) and the social environment can be aligned for sustainability. The natural environment in this study is the water resources, the artificial environment is micro hydroelectric power generation (MHPG), and the social environment is the community living around the MHPG. The existence of MHPG is intended for the sustainability of special electrical energy for areas not yet reached by electricity derived from the state electricity company (SEC). The utilization of MHPG Singalaga in South Ogan Komering Ulu (OKUS) district is not only intended for economic, ecological, and social sustainability in Southern OKU district especially those who live in Singalaga Village, Kisam Tinggi District. This paper discusses the economic, ecological and social benefits of water resources utilization in Southern OKU District for MHPG Singalaga. The direct economic benefits that arise for people living around MHPG Singalaga is the cost incurred by the community for the use of electricity is less than if the community uses electricity coming from outside the MHPG. The cost to society in the form of dues amounting to IDR 15,000 a month / household. Social benefits with the absorption of manpower to manage the MHPG is chairman, secretary and 3 members, while the ecological benefits of water resources and sustainable energy as well as the community while maintaining the natural vegetation that is located around the MHPG for the continuity of water resources.

This article explores how and why workplace environments impact diabetes management for adults people with Type 1 diabetes, 23-30 years of age. Interviews were conducted with 35 young adults, 29 women and 6 men. The majority of these interviewees worked in sectors such as banking, technology and administration. Young adults found it difficult to manage diabetes in the workplace for two main reasons: work-related time pressures and the non-routine nature of interviewees' work and working environment. Young adults also found it difficult to get the time to exercise both inside and outside of work. Young adults with Type 1 diabetes need to be provided with the tools and technologies that they need to manage diabetes in modern flexible workplaces. Copyright © 2014 Elsevier Ltd.

The learning context is learning English in an Internet environment. The examination of this learning process was based on the Biggs and Moore's teaching-learning model (Biggs & Moore, 1993). The research aims to explore the use of the deep and surface strategies in an Internet environment among EFL students who come from different socio-economic backgrounds. The results of the research may add an additional level to the understanding of students' functioning in the Internet environment. One hundred fourty-eight Israeli junior and high school students participated in this research. The methodology was based on special computer software: Screen Cam, which recorded the students' learning process. In addition, expert judges completed a questionnaire which examined and categorized the students' learning strategies. The research findings show a clear preference of participants from all socio-economic backgrounds towards the surface learning strategy. The findings also showed that students from the medium to high socio-economic background used both learning strategies more frequently than low socio-economic students. The results reflect the habits that students acquire during their adjustment process throughout their education careers. A brief encounter with the Internet learning environment apparently cannot change norms or habits, which were acquired in the non-Internet learning environment.

Economic development with limited supplies of family labor: Chinese peasant families in balancing demographic and economic requisites.

PubMed

Chang, K S

1991-07-01

Family planning (FP) in rural China, particularly the ramifications of the 1-child policy, has profound implications and ramifications for family-centered social and economic life in addition to demographic control. Under a constitutionally endorsed policy of strict birth control, favorable economic opportunities coexisted with the problem of familial labor shortages. Recent reform policies have led to a more relaxed FP environment. The Chinese state is in a dilemma between the need to allow peasant's autonomy in determining the familial work situation and the population pressure on the limited cultivated land. The Chinese experience of rural reform is examined in terms of the complex relationship between population change and economic development which are influenced by the production and welfare activities of the peasant family. The theoretical argument is that a family reliant strategy of economic reform undercuts the effectiveness of population control programs. The ultimate solution lies with sustained industrialization with high labor absorption. National trends and the Dahe People's Commune/Township experience are analyzed. Discussion is focused on the dilemma of FP and family production, old and new evidence of family size and economic performance, welfare outcome of family size, the role of the state in altering the demographic balance sheet, and the strategic response of peasant families to bring families of old designs back and urban migration and proletarianization. It is concluded that there is growing understanding that the causal relationships between population growth and economic development do not clearly support universal population control. Human social organization, not the man/land ratio, shapes the consequences of population growth. The implications for the Malthusian vs. Marxian debate for developing countries are that the resources/population imbalance needs to consider more carefully the human organizational factors. Mao's notions that a revolutionary transformation of the social organization of production in China would resolve overpopulation have since been rectified by opposing ideological positions: changing the basic mode of production through institutional decollectivization and checking population growth with the 1-child policy. This dilemma in rural areas translates to greater productivity and diversification with Chinese families having abundant adult labor and secured by the number of sons. It is difficult to substantiate the benefit of small families for peasants theoretically. Political rewards have been curtailed by economic declines. The peasant family has adapted by reconstituting old family forms and kin networks and by out-migration and nonagricultural employment.

Multiagent Flight Control in Dynamic Environments with Cooperative Coevolutionary Algorithms

Knudson, Matthew D.; Colby, Mitchell; Tumer, Kagan

2014-01-01

Dynamic flight environments in which objectives and environmental features change with respect to time pose a difficult problem with regards to planning optimal flight paths. Path planning methods are typically computationally expensive, and are often difficult to implement in real time if system objectives are changed. This computational problem is compounded when multiple agents are present in the system, as the state and action space grows exponentially. In this work, we use cooperative coevolutionary algorithms in order to develop policies which control agent motion in a dynamic multiagent unmanned aerial system environment such that goals and perceptions change, while ensuring safety constraints are not violated. Rather than replanning new paths when the environment changes, we develop a policy which can map the new environmental features to a trajectory for the agent while ensuring safe and reliable operation, while providing 92% of the theoretically optimal performance

The paper is devoted to the study of incentive schemes when developing socio-economic systems. The article analyzes the existing incentive schemes. It is established that the traditional incentive mechanisms do not fully take into account the specifics of the creation of each socio-economic system and, as a rule, are difficult to implement. The incentive schemes based on the full-scale simulation approach, which allow the most complete information from the existing projects of creation of socio-economic systems to be extracted, are proposed. The statement of the problem is given, the method and algorithm of the full-scale simulation study of the efficiency of incentive functions is developed. The results of the study are presented. It is shown that the use of quadratic and piecewise linear functions of incentive allows the time and costs for creating social and economic systems to be reduced by 10%-15%.

The issues of showing relations between environmental and economic indicators (further - environmental and economic interactions) of coke and by-product process are considered in the article. The purpose of the study is to reveal the regularities of the functioning of the local environmental and economic system on the basis of revealed spectrum of environmental and economic interactions. A simplified scheme of the environmental and economic system "coke and by-product process - the environment" was developed. The forms of the investigated environmental-economic interactions were visualized and the selective interpretation of the tightness of the established connection was made. The main result of the work is modeling system of environmental and economic interactions that allows increasing the efficiency of local ecological and economic system management and optimizing the "interests" of an industrial enterprise - the source of negative impact on the environment. The results of the survey can be recommended to government authorities and industrial enterprises with a wide range of negative impact forms to support the adoption of effective management decisions aimed at sustainable environmental and economic development of the region or individual municipalities.

Construction of a business model to assure financial sustainability of biobanks.

PubMed

Warth, Rainer; Perren, Aurel

2014-12-01

Biobank-suisse (BBS) is a collaborative network of biobanks in Switzerland. Since 2005, the network has worked with biobank managers towards a Swiss biobanking platform that harmonizes structures and procedures. The work with biobank managers has shown that long-term, sustainable financing is difficult to obtain. In this report, three typical biobank business models are identified and their characteristics analyzed. Five forces analysis was used to understand the competitive environment of biobanks. Data provided by OECD was used for financial estimations. The model was constructed using the business model canvas tool. The business models identified feature financing influenced by the economic situation and the research budgets in a given country. Overall, the competitive environment for biobanks is positive. The bargaining power with the buyer is negative since price setting and demand prediction is difficult. In Switzerland, the healthcare industry collects approximately 5600 U.S. dollars per person and year. If each Swiss citizen paid 0.1% (or 5 U.S. dollars) of this amount to Swiss biobanks, 45 million U.S. dollars could be collected. This compares to the approximately 10 million U.S. dollars made available for cohort studies, longitudinal studies, and pathology biobanks through science funding. With the same approach, Germany, the United States, Canada, France, and the United Kingdom could collect 361, 2634, 154, 264, and 221 million U.S. dollars, respectively. In Switzerland and in other countries, an annual fee less than 5 U.S. dollars per person is sufficient to provide biobanks with sustainable financing. This inspired us to construct a business model that not only includes the academic and industrial research sectors as customer segment, but also includes the population. The revenues would be collected as fees by the healthcare system. In Italy and Germany, a small share of healthcare spending is already used to finance selected clinical trials. The legal frameworks could serve as templates for the business model proposed here.

Many estates had early problems with architecture, construction and design. They proved an inhumane environment for many residents and there were frequent problems with communal features. Such estates were soon stigmatised and difficult to let as increasingly residual households were placed there, creating majority welfare-dependent estates. This created a downward spiral that traditional, and remote, housing management found difficult to address, and was too wide-scale to rectify financially within existing regimes. Prior to the 1980s, there were no specific government policies to tackle housing regeneration on high-rise estates. Problems became wider than traditional housing management and poor housing environments, encompassing social and economic exclusion. This paper, based on historical and contemporary literature as well as estate visits, reviews regeneration policy in three council housing estates within the London Borough of Brent. It traces successive government approaches since the 1980s from one that challenged the very status of council housing--notably at Stonebridge Park and Chalkhill, to one of partnership with the local authority--at South Kilburn. Housing policy is now concerned with more than just housing--it is about moving toward social inclusion, which requires initiative, flair, resource and commitment. It is about new accountabilities--not just numbers of bricks and mortar constructions, but about the lives, opportunities and health of those who live in an area. This fundamentally involves a partnership approach with residents at the centre of regeneration. This paper finds that sustainable estate regeneration policies are about continued improvements in both housing policy and social development.

The School Health Initiative: Environment, Learning, Disease (SHIELD) study is a novel school-based investigation of children's environmental health in economically disadvantaged urban neighborhoods of Minneapolis. This article describes the study design and summarizes lessons learned about recruiting and monitoring this historically understudied population. The SHIELD study focused on measuring children's exposures to multiple environmental stressors [volatile organic chemicals (VOCs), environmental tobacco smoke, allergens, bioaerosols, metals, pesticides, polychlorinated biphenyls (PCB), phthalates] and exploring related effects on respiratory health (e.g., lung function) and learning outcomes (e.g., standardized test scores, academic achievement). It involved intensive exposure monitoring, including environmental measurements inside and outside the children's schools and inside their homes, personal measurements with passive dosimeters worn by the children, and biological marker measurements in blood and urine. The SHIELD participants comprised a stratified random sample of 153 "index" children and 51 of their siblings enrolled in grades 2-5 at two adjacent elementary schools. The Minneapolis Public Schools (MPS) assisted with identifying, contacting, recruiting, and monitoring this population, which traditionally is difficult to study because families/children are highly mobile, speak a diversity of languages, frequently do not have a telephone, endure economic hardships, often do not trust researchers, and have a spectrum of unconventional lifestyles and living arrangements. Using a school-based approach, the overall SHIELD enrollment (response) rate was 56.7%, with a wide disparity between English-speaking (41.7%) and non-English-speaking (71.0%) families/children. Most children remained involved in the study through both monitoring sessions and exhibited an acceptable degree of compliance with study protocols, including providing blood and urine samples. Results indicate that it is both practical and affordable to conduct probability-based exposure studies in this population, but that it is also important to improve our understanding of factors (e.g., cultural, economic, psychological, social) affecting the willingness of families/children to participate in such studies, with special emphasis on developing cost-effective recruitment methods.

How much will be economic impact of climate change on water resources? A Meta-Analytic Review of previous literature

NASA Astrophysics Data System (ADS)

Yoshikawa, S.; Iseri, Y.; Kanae, S.

2016-12-01

Water resources is vital in social and economic activities. Total global water use is increasing, mainly due to economic and population growth in developing countries. It has one of risk with high agreement and robust evidence that freshwater-related risks of climate change increase significantly with increasing greenhouse gas concentrations. It is difficult to compare the risk with other field risk (e.g. agriculture, forestry, sea level rise) for considering both adaptation and mitigation policy with the level of decision makers and public servants. Economic impacts of climate change on water scarcity has been estimated by economic researchers. We have no certainty at all about integration between hydrological and economical fields on global scale. In this study, we highlight key concerns about conventional estimations of economic impact on water resources through meta-analysis. The economic impact on water resource in same base year using consumer price index is shown with increase in the global mean temperature. We clarified four concerns which are involved in 1) classification of economic mechanism, 2) estimated items of economic impact, 3) difference in estimating equations, and 4) definition of parameters related with economic impact of climate change. This study would be essential to next challenge as transdisciplinary research between hydrologic and economic fields.

Averting a Disaster with Groundwater Depletion in India: The General Case of Water Management Principles and Development (Invited)

NASA Astrophysics Data System (ADS)

Lall, U.

2013-12-01

Many countries, including the USA, China, and India are experiencing chronic groundwater depletion. In part this unsustainable water use results from climatic factors that reduce surface water availability and also the recharge to the aquifer system. However, a more critical factor is uncontrolled use for agriculture and energy and mineral processing. Interestingly in places such as India endowments have been politically created that lead to ever increasing use, through the provision of free energy for pumping. Reversing the situation is considered politically challenging, and the concept of metering and payment for what is essentially economic use of water is also considered difficult to apply. In this talk I use the Indian situation as a general example and discuss the role central planning strategies for demand and resource management can play recognizing the private action by millions of users as an inevitable tool that needs to be leveraged without necessarily the high transaction costs that come with monitoring and fee collection for monitored use. Specifically, targeting and stimulating potential cropping strategies and on farm water and energy management emerge as a choice in a difficult management environment. In a broader development context, I argue that the role of private sector aggregators in developing farm to market procurement strategies can play a role in both improving rural economies and providing a trajectory for more efficient water use through technology and crop choice.

The human and economic cost of hidden hunger.

Stein, Alexander J; Qaim, Matin

Micronutrient malnutrition is a public health problem in many developing countries. Its negative impact on income growth is recognized in principle, but there are widely varying estimates of the related economic cost. To discuss available studies that quantify the cost of micronutrient malnutrition, and to develop an alternative framework and apply it to India. Detailed burden of disease calculations are used to estimate the economic cost of micronutrient malnutrition based on disability-adjusted life years (DALYs) lost. The short-term economic cost of micronutrient malnutrition in India amounts to 0.8% to 2.5% of the gross domestic product. Although the results confirm that micronutrient malnutrition is a huge economic problem, the estimates are lower than those of most previous studies. The differences may be due to differences in underlying assumptions, quality of data, and precision of calculation, but also to dynamic interactions between nutrition, health, and economic productivity, which are difficult to capture. Clear explanation of all calculation details would be desirable for future studies in order to increase credibility and transparency.

A lack of response of the financial behaviors of biodiversity conservation nonprofits to changing economic conditions

PubMed Central

Larson, Eric R; Boyer, Alison G; Armsworth, Paul R

2014-01-01

The effectiveness of conservation organizations is determined in part by how they adapt to changing conditions. Over the previous decade, economic conditions in the United States (US) showed marked variation including a period of rapid growth followed by a major recession. We examine how biodiversity conservation nonprofits in the US responded to these changes through their financial behaviors, focusing on a sample of 90 biodiversity conservation nonprofits and the largest individual organization (The Nature Conservancy; TNC). For the 90 sampled organizations, an analysis of financial ratios derived from tax return data revealed little response to economic conditions. Similarly, more detailed examination of conservation expenditures and land acquisition practices of TNC revealed only one significant relationship with economic conditions: TNC accepted a greater proportion of conservation easements as donated in more difficult economic conditions. Our results suggest that the financial behaviors of US biodiversity conservation nonprofits are unresponsive to economic conditions. PMID:25512840

China's 30-year economic boom has created a unique social and economic market for commercial sex, as well as for a workforce of migrant women from rural China. This qualitative study explores the impact of the rapidly changing social and economic environment on migration patterns, knowledge of sexually transmitted infections (STIs), STI risk behaviours and health beliefs among female streetwalkers in Shanghai. Qualitative data were collected in 2010 through semi-structured in-depth interviews with 16 streetwalkers to characterise their migration passages, sexual health and behaviours, and peer networks. Many streetwalkers reported histories of childhood impoverishment, of family or partner violence or trauma, of migration consistent with the timeline and routes of economic development and of a scarcity in health, social or economic support. Their knowledge of the prevention and treatment of HIV and STIs was limited. They had little bargaining power on condom use and the majority resorted to vaginal douching and self-management with antibiotics as preventative measures. The study identifies streetwalkers' perspectives on the changing environment, their options and actions and, finally, HIV/STI risks that were unique to this hidden population.

Exploring experiences of the food environment among immigrants living in the Region of Waterloo, Ontario.

This exploratory study aimed to shed light on the role of the food environment in shaping food access among immigrants living in the Region of Waterloo, Ontario. In this qualitative case study, in-depth interviews aided by photovoice were conducted with nine immigrants, and key informant (KI) interviews were conducted with nine community stakeholders (e.g., settlement workers, planners) who held expert knowledge of the local context with respect to both the food system and experiences of immigrants in interacting with this system. In this paper, we focus specifically on insights related to the food environment, applying the Analysis Grid for Environments Linked to Obesity Framework to assess economic, physical, socio-cultural and political aspects. Economic features of the food environment, including food prices and differential costs of different types of food, emerged as factors related to food access. However, interactions with the food environment were shaped by broader economic factors, such as limited employment opportunities and low income. Most immigrants felt that they had good geographic access to food, though KIs expressed concerns about the types of outlet and food that were most accessible. Immigrants discussed social networks and cultural food practices, whereas KIs discussed political issues related to supporting food security in the Region. This exploratory case study is consistent with prior research in highlighting the economic constraints within which food access exists but suggests that there may be a need to further dissect food environments.

Evaluation of environmental impact produced by different economic activities with the global pollution index.

PubMed

Zaharia, Carmen

2012-07-01

The paper analyses the environment pollution state in different case studies of economic activities (i.e. co-generation electric and thermal power production, iron profile manufacturing, cement processing, waste landfilling, and wood furniture manufacturing), evaluating mainly the environmental cumulative impacts (e.g. cumulative impact against the health of the environment and different life forms). The status of the environment (air, water resources, soil, and noise) is analysed with respect to discharges such as gaseous discharges in the air, final effluents discharged in natural receiving basins or sewerage system, and discharges onto the soil together with the principal pollutants expressed by different environmental indicators corresponding to each specific productive activity. The alternative methodology of global pollution index (I (GP)*) for quantification of environmental impacts is applied. Environmental data analysis permits the identification of potential impact, prediction of significant impact, and evaluation of cumulative impact on a commensurate scale by evaluation scores (ES(i)) for discharge quality, and global effect to the environment pollution state by calculation of the global pollution index (I (GP)*). The I (GP)* values for each productive unit (i.e. 1.664-2.414) correspond to an 'environment modified by industrial/economic activity within admissible limits, having potential of generating discomfort effects'. The evaluation results are significant in view of future development of each productive unit and sustain the economic production in terms of environment protection with respect to a preventive environment protection scheme and continuous measures of pollution control.

Using support vector machine to predict eco-environment burden: a case study of Wuhan, Hubei Province, China.

The human socio-economic development depends on the planet's natural capital. Humans have had a considerable impact on the earth, such as resources depression and environment deterioration. The objective of this study was to assess the impact of socio-economic development on the ecological environment of Wuhan, Hubei Province, China, during the general planning period 2006-2020. Support vector machine (SVM) model was constructed to simulate the process of eco-economic system of Wuhan. Socio-economic factors of urban total ecological footprint (TEF) were selected by partial least squares (PLS) and leave-one-out cross validation (LOOCV). Historical data of socio-economic factors as inputs, and corresponding historical data of TEF as target outputs, were presented to identify and validate the SVM model. When predicted input data after 2005 were presented to trained model as generalization sets, TEFs of 2005, 2006,..., till 2020 were simulated as output in succession. Up to 2020, the district would have suffered an accumulative TEF of 28.374 million gha, which was over 1.5 times that of 2004 and nearly 3 times that of 1988. The per capita EF would be up to 3.019 gha in 2020. The simulation indicated that although the increase rate of GDP would be restricted in a lower level during the general planning period, urban ecological environment burden could not respond to the socio-economic circumstances promptly. SVM provides tools for dynamic assessment of regional eco-environment. However, there still exist limitations and disadvantages in the model. We believe that the next logical step in deriving better dynamic models of ecosystem is to integrate SVM and other algorithms or technologies.

To describe the living conditions of Senegalese adolescent girls according to their migration status, and to define the main socio-economic and biological determinants of their nutritional and growth status. Health and living conditions, sexual maturation, and nutritional and growth status of adolescent girls were determined within the framework of a longitudinal study on growth. The capital city of Senegal (Dakar) and a rural community (Niakhar), 120 km south-east of Dakar. Three hundred and thirty-one girls, 14.5-16.6 years of age, were recruited from the same villages. Thirty-six per cent of the sample remained in the villages to attend school and/or to help with household subsistence tasks (non-migrants). The remaining (64%) migrated to cities to work as maids (migrants) and lived in two different socio-economic environments: at the home of a guardian during the night and in the house of the employer during the daytime. Family rural environment and guardian and employer urban environments were socio-economically different (P < 0.001). Living conditions in urban areas were better than in rural areas and the employer's environment was socio-economically more favourable. Migrants had more advanced sexual maturation and higher body mass index (BMI), fat mass index (FMI) and mid-upper arm circumference than non-migrants. However, migrants were smaller than non-migrants. BMI, FMI and weight-for-age were related to socio-economic levels and duration of migration. Schooling was positively related to height and negatively related to BMI. Migrants enjoyed better living conditions than non-migrants. This could be partly due to the better socio-economic environment of the employer. It was associated with earlier puberty and better nutritional status, but not with a better growth.

Gender equity.

1999-01-01

This paper focuses on gender equity. Gender equity is difficult to achieve when there is no economic, social, or political equity. The Gender Development Index evidenced this. There were a lot of instances where women are psychologically traumatized, whether it is through domestic rape, purchased sexual services in the red light area, and seduction or violation of neighbors, relatives, daughter or child. The economic changes linked with globalization and media's influence have worsened women's position. The policy for empowerment of women is an attempt toward ensuring equity. Furthermore, many women and women's organizations are trying to address these inequities; wherein they fight for strong acceptance of women's rights, social, economic, and political rights, as well as equities between gender and within gender.

Economic Status and Adult Mortality in India: Is the Relationship Sensitive to Choice of Indicators?

PubMed

Barik, Debasis; Desai, Sonalde; Vanneman, Reeve

2018-03-01

Research on economic status and adult mortality is often stymied by the reciprocity of this relationship and lack of clarity on which aspect of economic status matters. While financial resources increase access to healthcare and nutrition and reduce mortality, sickness also reduces labor force participation, thereby reducing income. Without longitudinal data, it is difficult to study the linkage between economic status and mortality. Using data from a national sample of 132,116 Indian adults aged 15 years and above, this paper examines their likelihood of death between wave 1 of the India Human Development Survey (IHDS), conducted in 2004-2005 and wave 2, conducted in 2011-2012. The results show that mortality between the two waves is strongly linked to the economic status of the household at wave 1 regardless of the choice of indicator for economic status. However, negative relationship between economic status and mortality for individuals already suffering from cardiovascular and metabolic conditions varies between three markers of economic status - income, consumption and ownership of consumer durables - varies, reflecting two-way relationship between short and long term markers of economic status and morbidity.

2017-01-01

With rapid economic growth, South China has to face the most serious water pollution. However, whether or not such kind of water pollution is mainly caused by foreign trade is questionable. And, how the trade mode will be changed by pollution and corresponding regulation is also uncertain. In this paper, a fully endogenous model, which integrate economic growth, energy use and pollution, is designed to interpret the interrelation among these key variables in South China. Through this model, a new possibility of water environment Kuznets curve change has been investigated. Attribute to mixed two stage feasible general least square estimation method, we conclude that foreign trade has strong influence on environment change rate and the turning point. It can make the virtuous circle of between economic growth and environment improvement come early or later in different circumstances. Export and import play different role in such process and have counter effects on environment.

The article deals with the issues on economic techniques of occupational health and safety management. Authors’ definition of safety management is given. It is represented as a task-oriented process to identify, establish and maintain such a state of work environment in which there are no possible effects of hazardous and harmful factors, or their influence does not go beyond certain limits. It was noted that management techniques that are the part of the control mechanism, are divided into administrative, organizational and administrative, social and psychological and economic. The economic management techniques are proposed to be classified depending on the management subject, management object, in relation to an enterprise environment, depending on a control action. Technoeconomic study, feasibility study, planning, financial incentives, preferential crediting of enterprises, pricing, profit sharing and equity, preferential tax treatment for enterprises, economic regulations and standards setting have been distinguished as economic techniques.

Economic problems related to the prevention, diagnosis and treatment of rare diseases are presented paying particular attention to the costs of financing treatment, including the issue of its refund, which is a fundamental and difficult to solve economic problem of the health care system. Rare diseases, despite the low frequency of occurrence, together cover a large group of diseases being a serious medical, social and economic problem. The adoption of Polish National Plan for Rare Diseases resulting from the recommendations of the Council of the European Union, the extension of institutional activities related to the area of public health and social initiatives seeking innovative solutions to create a model of social support for patients and their families, with very high complexity of the issues regarding rare diseases, results in the need for a coherent, comprehensive, system operations and adoption of comprehensive solutions.

2015-07-07

Starting at least in the 1970s, empirical work suggested that demographic (population) and economic (affluence) forces are the key drivers of anthropogenic stress on the environment. We evaluate the extent to which politics attenuates the effects of economic and demographic factors on environmental outcomes by examining variation in CO2 emissions across US states and within states over time. We find that demographic and economic forces can in part be offset by politics supportive of the environment--increases in emissions over time are lower in states that elect legislators with strong environmental records.

Investigation of human-robot interface performance in household environments

NASA Astrophysics Data System (ADS)

Cremer, Sven; Mirza, Fahad; Tuladhar, Yathartha; Alonzo, Rommel; Hingeley, Anthony; Popa, Dan O.

2016-05-01

Today, assistive robots are being introduced into human environments at an increasing rate. Human environments are highly cluttered and dynamic, making it difficult to foresee all necessary capabilities and pre-program all desirable future skills of the robot. One approach to increase robot performance is semi-autonomous operation, allowing users to intervene and guide the robot through difficult tasks. To this end, robots need intuitive Human-Machine Interfaces (HMIs) that support fine motion control without overwhelming the operator. In this study we evaluate the performance of several interfaces that balance autonomy and teleoperation of a mobile manipulator for accomplishing several household tasks. Our proposed HMI framework includes teleoperation devices such as a tablet, as well as physical interfaces in the form of piezoresistive pressure sensor arrays. Mobile manipulation experiments were performed with a sensorized KUKA youBot, an omnidirectional platform with a 5 degrees of freedom (DOF) arm. The pick and place tasks involved navigation and manipulation of objects in household environments. Performance metrics included time for task completion and position accuracy.

Evaluating disturbance on mediterranean karst areas: the example of Sardinia (Italy)

NASA Astrophysics Data System (ADS)

de Waele, Jo

2009-07-01

Evaluating the human disturbance on karst areas is a difficult task because of the complexity of these peculiar and unique environments. The human impact on karstic geo-ecosystems is increasingly important and there is an increasing need for multidisciplinary tools to assess the environmental changes in karst areas. Many disciplines, such as biology, geomorphology, hydrology and social-economical sciences are to be considered to sufficiently evaluate the impact on these intrinsically vulnerable areas. This article gives an overview of the evolution of environmental impact on karst areas of the island Sardinia (Italy). For this particular case, the most important impacts in the past 50 years are derived from the following activities, in decreasing importance: (1) mining and quarrying; (2) deforestation, agriculture and grazing; (3) building (widespread urbanisation, isolated homes, etc.) and related infrastructures (roads, sewer systems, aqueducts, waste dumps, etc.); (4) tourism; (5) military activities. To evaluate the present environmental state of these areas the Disturbance Index for Karst environments [Van Beynen and Townsend (Environ Manage 36:101-116)] is applied in a slightly modified version. Instead of considering the indicators of environmental disturbances used in the original method, this slightly modified index evaluates the disturbances causing the deterioration of the environmental attributes. In the Sardinian case study, 27 disturbances have been evaluated, giving rise to the definition of a Disturbance Index ranging between 0 (Pristine) and 1 (highly disturbed). This Disturbance Index simplifies the original KDI method, appears to adequately measure disturbance on Mediterranean karst areas and could be applied with success to other similar regions.

Role of Sectoral Transformation in the Evolution of Water Management Norms in Agricultural Catchments: A Sociohydrologic Modeling Analysis

NASA Astrophysics Data System (ADS)

Roobavannan, M.; Kandasamy, J.; Pande, S.; Vigneswaran, S.; Sivapalan, M.

2017-10-01

This study is focused on the water-agriculture-environment nexus as it played out in the Murrumbidgee River Basin, eastern Australia, and how coevolution of society and water management actually transpired. Over 100 years of agricultural development the Murrumbidgee Basin experienced a "pendulum swing" in terms of water allocation, initially exclusively for agriculture production changing over to reallocation back to the environment. In this paper, we hypothesize that in the competition for water between economic livelihood and environmental wellbeing, economic diversification was the key to swinging community sentiment in favor of environmental protection, and triggering policy action that resulted in more water allocation to the environment. To test this hypothesis, we developed a sociohydrology model to link the dynamics of the whole economy (both agriculture and industry composed of manufacturing and services) to the community's sensitivity toward the environment. Changing community sensitivity influenced how water was allocated and governed and how the agricultural sector grew relative to the industrial sector (composed of manufacturing and services sectors). In this way, we show that economic diversification played a key role in influencing the community's values and preferences with respect to the environment and economic growth. Without diversification, model simulations show that the community would not have been sufficiently sensitive and willing enough to act to restore the environment, highlighting the key role of sectoral transformation in achieving the goal of sustainable agricultural development.

2010-12-01

The problem of E-waste has forced Environmental agencies of many countries to innovate, develop and adopt environmentally sound options and strategies for E-waste management, with a view to mitigate and control the ever growing threat of E-waste to the environment and human health. E-waste management is given the top priority in many developed countries, but in rapid developing countries like India, it is difficult to completely adopt or replicate the E-waste management system in developed countries due to many country specific issues viz. socio-economic conditions, lack of infrastructure, absence of appropriate legislations for E-waste, approach and commitments of the concerned, etc. This paper presents a review and assessment of the E-waste management system of developed as well as developing countries with a special emphasis on Switzerland, which is the first country in the world to have established and implemented a formal E-waste management system and has recycled 11kg/capita of WEEE against the target of 4kg/capita set by EU. And based on the discussions of various approaches, laws, legislations, practices of different countries, a road map for the development of sustainable and effective E-waste management system in India for ensuring environment, as well as, occupational safety and health, is proposed.

Using virtual reality to estimate aesthetic values of coral reefs

PubMed Central

Clifford, Sam; Caley, M. Julian; Pearse, Alan R.; Brown, Ross; James, Allan; Christensen, Bryce; Bednarz, Tomasz; Anthony, Ken; González-Rivero, Manuel; Mengersen, Kerrie; Peterson, Erin E.

2018-01-01

Aesthetic value, or beauty, is important to the relationship between humans and natural environments and is, therefore, a fundamental socio-economic attribute of conservation alongside other ecosystem services. However, beauty is difficult to quantify and is not estimated well using traditional approaches to monitoring coral-reef aesthetics. To improve the estimation of ecosystem aesthetic values, we developed and implemented a novel framework used to quantify features of coral-reef aesthetics based on people's perceptions of beauty. Three observer groups with different experience to reef environments (Marine Scientist, Experienced Diver and Citizen) were virtually immersed in Australian's Great Barrier Reef (GBR) using 360° images. Perceptions of beauty and observations were used to assess the importance of eight potential attributes of reef-aesthetic value. Among these, heterogeneity, defined by structural complexity and colour diversity, was positively associated with coral-reef-aesthetic values. There were no group-level differences in the way the observer groups perceived reef aesthetics suggesting that past experiences with coral reefs do not necessarily influence the perception of beauty by the observer. The framework developed here provides a generic tool to help identify indicators of aesthetic value applicable to a wide variety of natural systems. The ability to estimate aesthetic values robustly adds an important dimension to the holistic conservation of the GBR, coral reefs worldwide and other natural ecosystems. PMID:29765676

Emerging nanotechnology based strategies for diagnosis and therapeutics of urinary tract infections: A review.

PubMed

Kumar, M S; Das, A P

2017-11-01

At present, various diagnostic and therapeutic approaches are available for urinary tract infections. But, still the quest for development of more rapid, accurate and reliable approach is an unending process. The pathogens, especially uropathogens are adapting to new environments and antibiotics day by day rapidly. Therefore, urinary tract infections are evolving as hectic and difficult to eradicate, increasing the economic burden to the society. The technological advances should be able to compete the adaptability characteristics of microorganisms to combat their growth in new environments and thereby preventing their infections. Nanotechnology is at present an extensively developing area of immense scientific interest since it has diverse potential applications in biomedical field. Nanotechnology may be combined with cellular therapy approaches to overcome the limitations caused by conventional therapeutics. Nanoantibiotics and drug delivery using nanotechnology are currently growing areas of research in biomedical field. Recently, various categories of antibacterial nanoparticles and nanocarriers for drug delivery have shown their potential in the treatment of infectious diseases. Nanoparticles, compared to conventional antibiotics, are more beneficial in terms of decreasing toxicity, prevailing over resistance and lessening costs. Nanoparticles present long term therapeutic effects since they are retained in body for relatively longer periods. This review focuses on recent advances in the field of nanotechnology, principally emphasizing diagnostics and therapeutics of urinary tract infections. Copyright © 2017 Elsevier B.V.

Expression of a soluble truncated Vargula luciferase in Escherichia coli.

Hunt, Eric A; Moutsiopoulou, Angeliki; Broyles, David; Head, Trajen; Dikici, Emre; Daunert, Sylvia; Deo, Sapna K

2017-04-01

Marine luciferases are regularly employed as useful reporter molecules across a range of various applications. However, attempts to transition expression from their native eukaryotic environment into a more economical prokaryotic, i.e. bacterial, expression system often presents several challenges. Specifically, bacterial protein expression inherently lacks chaperone proteins to aid in the folding process, while Escherichia coli presents a reducing cytoplasmic environment in. These conditions contribute to the inhibition of proper folding of cysteine-rich proteins, leading to incorrect tertiary structure and ultimately inactive and potentially insoluble protein. Vargula luciferase (Vluc) is a cysteine-rich marine luciferase that exhibits glow-type bioluminescence through a reaction between its unique native substrate and molecular oxygen. Because most other commonly used bioluminescent proteins exhibit flash-type emission kinetics, this emission characteristic of Vluc is desirable for high-throughput applications where stability of emission is required for the duration of data collection. A truncated form of Vluc that retains considerable bioluminescence activity (55%) compared to the native full-length protein has been reported in the literature. However, expression and purification of this luciferase from bacterial systems has proven difficult. Herein, we demonstrate the expression and purification of a truncated form of Vluc from E. coli. This truncated Vluc (tVluc) was subsequently characterized in terms of both its biophysical and bioluminescence properties. Copyright © 2017 Elsevier Inc. All rights reserved.

Aesthetic value, or beauty, is important to the relationship between humans and natural environments and is, therefore, a fundamental socio-economic attribute of conservation alongside other ecosystem services. However, beauty is difficult to quantify and is not estimated well using traditional approaches to monitoring coral-reef aesthetics. To improve the estimation of ecosystem aesthetic values, we developed and implemented a novel framework used to quantify features of coral-reef aesthetics based on people's perceptions of beauty. Three observer groups with different experience to reef environments (Marine Scientist, Experienced Diver and Citizen) were virtually immersed in Australian's Great Barrier Reef (GBR) using 360° images. Perceptions of beauty and observations were used to assess the importance of eight potential attributes of reef-aesthetic value. Among these, heterogeneity, defined by structural complexity and colour diversity, was positively associated with coral-reef-aesthetic values. There were no group-level differences in the way the observer groups perceived reef aesthetics suggesting that past experiences with coral reefs do not necessarily influence the perception of beauty by the observer. The framework developed here provides a generic tool to help identify indicators of aesthetic value applicable to a wide variety of natural systems. The ability to estimate aesthetic values robustly adds an important dimension to the holistic conservation of the GBR, coral reefs worldwide and other natural ecosystems.

A framework for assessing health system resilience in an economic crisis: Ireland as a test case

PubMed Central

2013-01-01

Background The financial crisis that hit the global economy in 2007 was unprecedented in the post war era. In general the crisis has created a difficult environment for health systems globally. The purpose of this paper is to develop a framework for assessing the resilience of health systems in terms of how they have adjusted to economic crisis. Resilience can be understood as the capacity of a system to absorb change but continue to retain essentially the same identity and function. The Irish health system is used as a case study to assess the usefulness of this framework. Methods The authors identify three forms of resilience: financial, adaptive and transformatory. Indicators of performance are presented to allow for testing of the framework and measurement of system performance. Both quantitative and qualitative methods were used to yield data for the Irish case study. Quantitative data were collected from government documents and sources to understand the depth of the recession and the different dimensions of the response. Semi-structured interviews were conducted with key decision makers to understand the reasons for decisions made. Results In the Irish case there is mixed evidence on resilience. Health funding was initially protected but was then followed by deep cuts as the crisis deepened. There is strong evidence for adaptive resilience, with the health system showing efficiency gains from the recession. Nevertheless, easy efficiencies have been made and continued austerity will mean cuts in entitlements and services. The prospects for building and maintaining transformatory resilience are unsure. While the direction of reform is clear, and has been preserved to date, it is not certain whether it will remain manageable given continued austerity, some loss of sovereignty and capacity limitations. Conclusions The three aspects of resilience proved a useful categorisation of performance measurement though there is overlap between them. Transformatory resilience may be more difficult to assess precisely. It would be useful to test out the framework against other country experiences and refine the measures and indicators. Further research on both the comparative resilience of different health systems and building resilience in preparation for crises is encouraged. PMID:24171814

Lignite is a low-quality energy source which accounts for 13 % of China's coal reserves. It is imperative to improve the quality of lignite for large-scale utilization. To further explore and analyze the influence of various key processes on the environment and economic costs, a lignite drying and compression technology is evaluated using an integrated approach of life cycle assessment and life cycle costs. Results showed that lignite mining, direct air emissions, and electricity consumption have most significant impacts on the environment. An integrated evaluation of life cycle assessment and life cycle costs showed that the most significant contributor to the environmental impacts and economic costs was the lignite mining process. The impact of transportation and wastewater treatment process on the environment and economic costs was small enough to be ignored. Critical factors were identified for reducing the environmental and economic impacts of lignite drying and compression technology. These findings provide useful inputs for both industrial practice and policy making for exploitation, processing, and utilization of lignite resources.

A Study of Economical Incentives for Voltage Profile Control Method in Future Distribution Network

NASA Astrophysics Data System (ADS)

Tsuji, Takao; Sato, Noriyuki; Hashiguchi, Takuhei; Goda, Tadahiro; Tange, Seiji; Nomura, Toshio

In a future distribution network, it is difficult to maintain system voltage because a large number of distributed generators are introduced to the system. The authors have proposed “voltage profile control method” using power factor control of distributed generators in the previous work. However, the economical disbenefit is caused by the active power decrease when the power factor is controlled in order to increase the reactive power. Therefore, proper incentives must be given to the customers that corporate to the voltage profile control method. Thus, in this paper, we develop a new rules which can decide the economical incentives to the customers. The method is tested in one feeder distribution network model and its effectiveness is shown.

Introduction Policy and regulatory interventions aimed at creating environments more conducive to physical activity (PA) are an important component of strategies to improve population levels of PA. However, many potentially effective policies are not being broadly implemented. This study sought to identify potential policy/regulatory interventions targeting PA environments, and barriers/facilitators to their implementation at the Australian state/territory government level. Methods In-depth interviews were conducted with senior representatives from state/territory governments, statutory authorities and non-government organisations (n = 40) to examine participants': 1) suggestions for regulatory interventions to create environments more conducive to PA; 2) support for preselected regulatory interventions derived from a literature review. Thematic and constant comparative analyses were conducted. Results Policy interventions most commonly suggested by participants fell into two areas: 1) urban planning and provision of infrastructure to promote active travel; 2) discouraging the use of private motorised vehicles. Of the eleven preselected interventions presented to participants, interventions relating to walkability/cycling and PA facilities received greatest support. Interventions involving subsidisation (of public transport, PA-equipment) and the provision of more public transport infrastructure received least support. These were perceived as not economically viable or unlikely to increase PA levels. Dominant barriers were: the powerful ‘road lobby’, weaknesses in the planning system and the cost of potential interventions. Facilitators were: the provision of evidence, collaboration across sectors, and synergies with climate change/environment agendas. Conclusion This study points to how difficult it will be to achieve policy change when there is a powerful ‘road lobby’ and government investment prioritises road infrastructure over PA-promoting infrastructure. It highlights the pivotal role of the planning and transport sectors in implementing PA-promoting policy, however suggests the need for clearer guidelines and responsibilities for state and local government levels in these areas. Health outcomes need to be given more direct consideration and greater priority within non-health sectors. PMID:23028434

Using prospective, longitudinal data spanning 10 years (age 10 to 20) from a study of 295 economically disadvantaged males, the current investigation evaluated a developmental model that links early family environment and later educational aspirations, extracurricular activities, and educational attainment to substance use in early adulthood. The results indicate that a positive family environment during adolescence (low family conflict, high family warmth, and effective child management) predicted educational involvements during adolescence that promoted educational attainment during early adulthood. Finally, higher levels of educational attainment were associated with less substance use in early adulthood, even after controlling for adolescent substance use. These findings suggest that positive parenting promotes educational achievements that increase resilience to substance use for economically disadvantaged males. PMID:26307026

Use of Multiple Data Sources to Estimate the Economic Cost of Dengue Illness in Malaysia

PubMed Central

Shepard, Donald S.; Undurraga, Eduardo A.; Lees, Rosemary Susan; Halasa, Yara; Lum, Lucy Chai See; Ng, Chiu Wan

2012-01-01

Dengue represents a substantial burden in many tropical and sub-tropical regions of the world. We estimated the economic burden of dengue illness in Malaysia. Information about economic burden is needed for setting health policy priorities, but accurate estimation is difficult because of incomplete data. We overcame this limitation by merging multiple data sources to refine our estimates, including an extensive literature review, discussion with experts, review of data from health and surveillance systems, and implementation of a Delphi process. Because Malaysia has a passive surveillance system, the number of dengue cases is under-reported. Using an adjusted estimate of total dengue cases, we estimated an economic burden of dengue illness of US$56 million (Malaysian Ringgit MYR196 million) per year, which is approximately US$2.03 (Malaysian Ringgit 7.14) per capita. The overall economic burden of dengue would be even higher if we included costs associated with dengue prevention and control, dengue surveillance, and long-term sequelae of dengue. PMID:23033404

Public health policy decisions on medical innovations: what role can early economic evaluation play?

PubMed

Hartz, Susanne; John, Jürgen

2009-02-01

Our contribution aims to explore the different ways in which early economic data can inform public health policy decisions on new medical technologies. A literature research was conducted to detect methodological contributions covering the health policy perspective. Early economic data on new technologies can support public health policy decisions in several ways. Embedded in horizon scanning and HTA activities, it adds to monitoring and assessment of innovations. It can play a role in the control of technology diffusion by informing coverage and reimbursement decisions as well as the direct public promotion of healthcare technologies, leading to increased efficiency. Major problems include the uncertainty related to economic data at early stages as well as the timing of the evaluation of an innovation. Decision-makers can benefit from the information supplied by early economic data, but the actual use in practice is difficult to determine. Further empirical evidence should be gathered, while the use could be promoted by further standardization.

An overall estimation of losses caused by diseases in the Brazilian fish farms.

PubMed

Tavares-Dias, Marcos; Martins, Maurício Laterça

2017-12-01

Parasitic and infectious diseases are common in finfish, but are difficult to accurately estimate the economic impacts on the production in a country with large dimensions like Brazil. The aim of this study was to estimate the costs caused by economic losses of finfish due to mortality by diseases in Brazil. A model for estimating the costs related to parasitic and bacterial diseases in farmed fish and an estimative of these economic impacts are presented. We used official data of production and mortality of finfish for rough estimation of economic losses. The losses herein presented are related to direct and indirect economic costs for freshwater farmed fish, which were estimated in US$ 84 million per year. Finally, it was possible to establish by the first time an estimative of overall losses in finfish production in Brazil using data available from production. Therefore, this current estimative must help researchers and policy makers to approximate the economic costs of diseases for fish farming industry, as well as for developing of public policies on the control measures of diseases and priority research lines.

This paper represents the strategy for development of the Polish Electricity Sector dealing with specific problems which are common for all of East Central Europe. In 1990 Poland adopted a restructuring program for the entire energy sector. Very ambitious plans were changed several times but still the main direction of change was preserved. The most difficult period of transformation is featured by several contradictions which have to be balanced. Electricity prices should increase in order to cover the modernization and development program but the society is not able to take this burden in such a short time. Furthermore the newmore » environment protection standards force the growth of capital investment program which sooner or later has to be transferred through the electricity prices. New economic mechanisms have to be introduced to the electricity sector to replace the old ones noneffective, centrally planned. This process has to follow slow management changes. Also, introduction of new electricity market is limited by those constraints. However, this process of change would not be possible without parallel governmental initiation like preparation of new energy law and regulatory frames.« less

The role of pulmonology in the National Health System Chronicity Strategy.

2015-08-01

Longer life expectancy and the progressive aging of the population is changing the epidemiological pattern of healthcare, with a reduction in the incidence of acute diseases and a marked increase in chronic diseases. This change brings important social, healthcare and economic consequences that call for a reorganization of patient care. In this respect, the Spanish National Health System has developed a Chronicity strategy that proposes a substantial change in focus from traditional rescue medicine to patient- and environment-centered care, with a planned, proactive, participative and multidisciplinary approach. Some of the more common chronic diseases are respiratory. In COPD, this integrated approach has been effective in reducing exacerbations, improving quality of life, and even reducing costs. However, the wide variety of management strategies, not only in COPD but also in asthma and other respiratory diseases, makes it difficult to draw definitive conclusions. Pulmonologists can and must participate in the new chronicity models and contribute their knowledge, experience, innovation, research, and special expertise to the development of these new paradigms.

Wireless Sensor Networks (WSNs) are gaining tremendous importance thanks to their broad range of commercial applications such as in smart home automation, health-care and industrial automation. In these applications multi-vendor and heterogeneous sensor nodes are deployed. Due to strict administrative control over the specific WSN domains, communication barriers, conflicting goals and the economic interests of different WSN sensor node vendors, it is difficult to introduce a large scale federated WSN. By allowing heterogeneous sensor nodes in WSNs to coexist on a shared physical sensor substrate, virtualization in sensor network may provide flexibility, cost effective solutions, promote diversity, ensure security and increase manageability. This paper surveys the novel approach of using the large scale federated WSN resources in a sensor virtualization environment. Our focus in this paper is to introduce a few design goals, the challenges and opportunities of research in the field of sensor network virtualization as well as to illustrate a current status of research in this field. This paper also presents a wide array of state-of-the art projects related to sensor network virtualization. PMID:22438759

2009-06-01

Electrochemical machining has traditionally been used in highly specialized fields, such as those of the aerospace and defense industries. It is now increasingly being applied in other industries, where parts with difficult-to-cut material, complex geometry and tribology, and devices of nanoscale and microscale are required. Electric characteristic plays a principal function role in and chemical characteristic plays an assistant function role in electrochemical machining. Therefore, essential parameters in electrochemical machining can be described current density, machining time, inter-electrode gap size, electrolyte, electrode shape etc. Electrochemical machining provides an economical and effective method for machining high strength, high tension and heat-resistant materials into complex shapes such as turbine blades of titanium and aluminum alloys. The application of nanoscale voltage pulses between a tool electrode and a workpiece in an electrochemical environment allows the three-dimensional machining of conducting materials with sub-micrometer precision. In this study, micro probe are developed by electrochemical etching and micro holes are manufactured using these micro probe as tool electrodes. Micro holes and microgroove can be accurately achieved by using nanoscale voltages pulses.

Although formally in place, health services are deprived of any means to assist the population. From 1600 respondents 58,8% paid for medical bills on their own, and 8.7% of respondents had health insurance that covered medical and health expenses. Almost every fifth respondent (18.5%) had access to supplemental financial support from friends and relatives. The vast majority of respondents considered the care received from medical services providers as being positive. 17.8% of respondents evaluated it as having been "very good", and every second out of five respondents (42.7%) evaluated it as having been "good". Every twentieth patient (5.2%) evaluated it as "poor" and 3.7% -"very bad", 29% of respondents are affiliated with various governmental programs. Social-economic situation influenced on the accessibility to the medical care. An effective of social policy is the system of prevention of risk factors.

[SmartCare: automatizing clinical guidelines].

PubMed

Mersmann, Stefan

2009-10-01

In critical care environments, important medical and economic challenges are presented by the enhancement of therapeutic quality and the reduction of therapeutic costs. For this purpose, several clinical studies have demonstrated a positive impact of the adoption of so-called clinical guidelines. Clinical guidelines represent well documented best practices in healthcare and are fundamental aspects of evidence-based medicine. However, at the bedside, such clinical guidelines remain difficult to use by clinical staff. The knowledge-based technology SmartCare allows incorporation of arbitrary computerized clinical guidelines into various medical target systems. SmartCare constitutes a clinical guideline engine because it executes one or more clinical guidelines on a specific medical device. SmartCare was initially applied for the automated control of a mechanical ventilator to assist the process of weaning from a medical device. The methodology allows further applications to be implemented effectively with other medical devices and/or with other appropriate guidelines. In this paper, we report on the methodology and the resulting versatility of such a system, as well as the clinical evaluation of SmartCare/PS and its perspectives.

Analytical investigation of a three-dimensional FRP-retrofitted reinforced concrete structure's behaviour under earthquake load effect in ANSYS program

Altun, F.; Birdal, F.

2012-12-01

In this study, a 1:3 scaled, three-storey, FRP (Fiber Reinforced Polymer) retrofitted reinforced concrete model structure whose behaviour and crack development were identified experimentally in the laboratory was investigated analytically. Determination of structural behaviour under earthquake load is only possible in a laboratory environment with a specific scale, as carrying out structural experiments is difficult due to the evaluation of increased parameter numbers and because it requires an expensive laboratory setup. In an analytical study, structure was modelled using ANSYS Finite Element Package Program (2007), and its behaviour and crack development were revealed. When experimental difficulties are taken into consideration, analytical investigation of structure behaviour is more economic and much faster. At the end of the study, experimental results of structural behaviour and crack development were compared with analytical data. It was concluded that in a model structure retrofitted with FRP, the behaviour and cracking model can be determined without testing by determining the reasons for the points where analytical results are not converged with experimental data. Better understanding of structural behaviour is analytically enabled with the study.

One-stage free-vortex aerodynamic window with pressure ratio 100 and atmospheric exhaust

NASA Astrophysics Data System (ADS)

Malkov, Victor M.; Trilis, A. V.; Savin, Andrew V.; Druzhinin, S. L.

2005-03-01

The aerodynamic windows (AW) are intended for a high power extraction from the gas laser optical cavity, where the pressure is much lower than environment pressure. The main requirements for the aerodynamic windows are to satisfy a low level of optical disturbances in a laser beam extraction channel and an air leakage absence into the optical cavity. Free vortex AW are most economic from a point of working gas consumption and the greatest pressure differential is realized on them at an exhaust to atmosphere. For ideal gas it is possible to receive as much as large pressure differential, however for real gas a pressure differential more than P>=50 is difficult to achieve. To achieve the pressure ratio 100 in free vortex single-stage AW the method of stabilizing of boundary layer was used. The gas of curtain was decelerated in the diffuser and was exhausted into the atmosphere straightly. The pressure recovery improvement was achieved by using the boundary layer blowing inside the diffuser. Only 10% of total mass flow was used for boundary layer blowing.

Agroterrorism: the risks to the United States food supply and national security.

PubMed

Gill, Kevin M

2015-01-01

Agroterrorism is a collective term that describes an intentional criminal attack against crops or mankind using viral, bacterial, fungal, or insect-borne agents. Agroterrorism also includes attacks against animals using infectious pathogens such as Burkholderia mallei (glanders), Bacillus anthracis (anthrax), viral avian influenza, foot and mouth disease, and several equine encephalitis viruses. Agents that could be used against crops include the causative agents of wheat blast, rice blast, rice brown spot disease, and wheat stem rust. The primary goal of terrorists using agroterrorism is to spread fear and cause massive economic loss. Subsequent goals include causing disease and death to humans and animals. The use of bioterrorism agents is a much more practical approach than using explosives, for example, to achieve those results since many of these biological agents are commonly found naturally in the environment and are difficult to detect with modern technology. The effective use of biological warfare dates back centuries and can still can be employed by terrorist groups, lone wolves, and political and religious groups to cause death and mayhem on a grand scale.

Genomic Analysis of Differentiation between Soil Types Reveals Candidate Genes for Local Adaptation in Arabidopsis lyrata

Turner, Thomas L.; von Wettberg, Eric J.; Nuzhdin, Sergey V.

2008-01-01

Serpentine soil, which is naturally high in heavy metal content and has low calcium to magnesium ratios, comprises a difficult environment for most plants. An impressive number of species are endemic to serpentine, and a wide range of non-endemic plant taxa have been shown to be locally adapted to these soils. Locating genomic polymorphisms which are differentiated between serpentine and non-serpentine populations would provide candidate loci for serpentine adaptation. We have used the Arabidopsis thaliana tiling array, which has 2.85 million probes throughout the genome, to measure genetic differentiation between populations of Arabidopsis lyrata growing on granitic soils and those growing on serpentinic soils. The significant overrepresentation of genes involved in ion transport and other functions provides a starting point for investigating the molecular basis of adaptation to soil ion content, water retention, and other ecologically and economically important variables. One gene in particular, calcium-exchanger 7, appears to be an excellent candidate gene for adaptation to low Ca∶Mg ratio in A. lyrata. PMID:18784841

With the continuous development of the economy of the Shandong Province watershed, a large number of pollutant emission, resulting in water quality of the basin has undergone significant changes. To study the Shandong Province watershed economic development and the relationship between the discharge of pollutants, in this paper, the relationship between economic growth and pollutant emissions in the Shandong Province watershed was established by Shandong Province watershed in 2002-2015 per capita GDP and wastewater, COD, ammonia nitrogen(AN) pollutant emissions. The data were analyzed by software such as SPSS, and the cubic equation model between various pollutants and economic indexes was fitted. To further make the relationship between pollutants and economic development map to study the conventional pollutant emissions and economic development trends. It is found that only the relationship between industrial wastewater discharge and per capita GDP is most coordinated, that is, industrial wastewater emissions with the continuous development of the basin economy, showing a tendency to rise first and then fall. Finally, ultimately based on the results of the study of the water environment and economic development proposals were proposed.

It is well-known in the industry that geothermal power projects will generate positivemore » economic impacts for their host regions. Our aim in the assessment of these impacts includes quantification of the increase in overall economic output due to geothermal projects and of the job creation associated with this increase. Such an estimate of economic impacts of geothermal investments on employment, energy and the environment will also help us understand the contributions that the geothermal industry will have in achieving a sustainable path towards energy production.« less

Health economic studies: an introduction to cost-benefit, cost-effectiveness, and cost-utility analyses.

PubMed

Angevine, Peter D; Berven, Sigurd

2014-10-15

Narrative overview. To provide clinicians with a basic understanding of economic studies, including cost-benefit, cost-effectiveness, and cost-utility analyses. As decisions regarding public health policy, insurance reimbursement, and patient care incorporate factors other than traditional outcomes such as satisfaction or symptom resolution, health economic studies are increasingly prominent in the literature. This trend will likely continue, and it is therefore important for clinicians to have a fundamental understanding of the common types of economic studies and be able to read them critically. In this brief article, the basic concepts of economic studies and the differences between cost-benefit, cost-effectiveness, and cost-utility studies are discussed. An overview of the field of health economic analysis is presented. Cost-benefit, cost-effectiveness, and cost-utility studies all integrate cost and outcome data into a decision analysis model. These different types of studies are distinguished mainly by the way in which outcomes are valued. Obtaining accurate cost data is often difficult and can limit the generalizability of a study. With a basic understanding of health economic analysis, clinicians can be informed consumers of these important studies.

Summit on Improving the Economics of America's Nuclear Power Plants

Collins, John; Mason, Charles

The Summit on Improving the Economics of America’s Nuclear Power Plants was convened May 19, 2016, by Secretary of Energy Ernest Moniz and co-sponsored by Idaho Senator Mike Crapo to stress the importance of existing nuclear reactors in meeting our nation’s energy goals. The summit was also designed to identify and discuss policy options that can be pursued at federal and state levels to address economic challenges, as well as technical options that utilities can use to improve the economic competitiveness of operating nuclear power plants (NPPs) and avoid early plant retirements that are driven by temporary market conditions. Themore » owners of NPPs face difficult economic decisions and are working to improve the performance of existing NPPs. However, it soon became clear that some of the actions taken by states and regional markets have had an impact on the economic viability of existing power plants, including carbon free NPPs. Summit speakers identified concepts and actions that could be taken at state and federal levels to improve the economics of the existing fleet within these regulated and restructured electricity markets. This report summarizes the speeches, concepts, and actions taken.« less

Urbanization and Greenhouse Gas Emissions from Industry

Didenko, N. I.; Skripnuk, D. F.; Mirolyubova, O. V.

2017-06-01

This article analyses the global environment. The article describes processes that characterize the global environment, specific indicators are suggested, that can be used to measure the change in the global environment. It is said that cities and all urbanized territories have a negative effect on the global environment. Originally, the authors wanted to call the article «City as a source of destruction of the global environment». But taking into account the fact that urbanization contributes to improving the economic efficiency of the state, cities are the centers of the economic, cultural and informational potential that provide a «breakthrough» into the development of the economy. The article assesses the impact of urbanization on the global environment. For the analysis of the impact of urbanization on the natural habitat, the autoregressive distributed lags (ADL-model) are chosen.

According to the overall requirements of ecological construction and environmental protection, rely on the national key ecological engineering, strengthen ecological environmental restoration and protection, improve forest cover, control soil erosion, construct important ecological security barrier in poor areas, inhibit poverty alleviation through ecological security in this area from environmental damage to the vicious cycle of poverty. Obviously, the dynamic monitoring of ecological security in contiguous destitute areas of Sichuan province has a policy sense of urgency and practical significance. This paper adopts RS technology and GIS technology to select the Luhe region of Jinchuan county and Ganzi prefecture as the research area, combined with the characteristics of ecological environment in poor areas, the impact factors of ecological environment are determined as land use type, terrain slope, vegetation cover, surface water, soil moisture and other factors. Using the ecological environmental safety assessment model, the ecological environment safety index is calculated. According to the index, the ecological environment safety of the research area is divided into four levels. The ecological environment safety classification map of 1990 in 2009 is obtained. It can be seen that with the human modern life and improve their economic level, the surrounding environment will be destroyed, because the research area ecological environment is now in good, the ecological environment generally tends to be stable. We should keep its ecological security good and improve local economic income. The relationship between ecological environmental security and economic coordinated development in poor areas has very important strategic significance.

Singapore's economic internationalization and its effects on work and family.

PubMed

Chia, A

2000-04-01

There are tensions between Singapore's economic strategy of internationalization and the emphasis on family life. Frequent travelers, unaccompanied expatriates, and their families experience these tensions. The frequent or extended absences of frequent travelers and expatriates make it difficult for them to fulfill their family roles and obligations, and may lead to estrangement from their families. Families who are left behind may face role conflict and role strain, but actually draw closer in their efforts to cope with the absence of their absent members. Researchers, policy-makers, and employers can contribute towards reducing the tensions between internationalization and family togetherness.

Azam, Muhammad; Khan, Abdul Qayyum

2017-07-01

This study examines the impact of economic growth, corruption, health, and poverty on environmental degradation for three countries from ASEAN, namely Indonesia, Malaysia, and Thailand using annual data over the period of 1994-2014. The relationship between environmental degradation (pollution) by carbon dioxide (CO 2 ) emissions and economic growth is examined along with some other variables, namely health expenditure, poverty, agriculture value added growth, industrial value added growth, and corruption. The ordinary least squares (OLS) method is applied as an analytical technique for parameter estimation. The empirical results reveal that almost all variables are statistically significant at the 5% level of significance, whereby test rejects the null hypotheses of non-cointegration, indicating that all variables play an important role in affecting the environment across countries. Empirical results also indicate that economic growth has significant positive impact, while health expenditures show significantly negative impact on the environment. Corruption has significant positive effect on environment in the case of Malaysia; while in the case of Indonesia and Thailand, it has insignificant results. However, for the individual analysis across countries, the regression estimate suggests that economic growth has a significant positive relationship with environment for Indonesia, while it is found insignificantly negative and positive in the case of Malaysia and Thailand, respectively, during the period under the study. Empirical findings of the study suggest that policy-makers require to make technological-friendly environment sequentially to surmount unregulated pollution, steady population transfers from rural areas to urban areas are also important, and poverty alleviation and better health provision can also help to improve the environment.

Wang, Wenyi; Zeng, Weihua; Yao, Bo

2014-01-01

Many rapidly developing regions have begun to draw the attention of the world. Meanwhile, the energy and environmental issues associated with rapid economic growth have aroused widespread critical concern. Therefore, studying energy, economic, and environmental systems is of great importance. This study establishes a system dynamic model that covers multiple aspects of those systems, such as energy, economy, population, water pollution, air pollution, solid waste, and technology. The model designed here attempts to determine the impacts of socioeconomic development on the energy and environment of Tongzhou District in three scenarios: under current, planning, and sustainable conditions. The results reveal that energy shortages and water pollutions are very serious and are the key issues constraining future social and economic development. Solid waste emissions increase with population growth. The prediction results provide valuable insights into social advancement.

PubMed

Shapiro, J; Lie, D

2000-07-01

Despite significant clinical and research efforts aimed at recognizing and managing "difficult" patients, such patients remain a frustrating experience for many clinicians. This is especially true for primary care residents, who are required to see a significant volume of patients with diverse and complex problems, but who may not have adequate training and life experience to enable them to deal with problematic doctor-patient situations. Literature--short stories, poems, and patient narratives--is a little-explored educational tool to help residents in understanding and working with difficult patients. In this report, the authors examine the mechanics of using literature to teach about difficult patients, including structuring the learning environment, establishing learning objectives, identifying teaching resources and appropriate pedagogic methods, and incorporating creative writing assignments. They also present an illustrative progression of a typical literature-based teaching session about a difficult patient.

The Aral Sea crisis is the most prominent environmental problem in building Silk Road and Economic Belt, which is mainly induced by extensive exploitation of land resources in Aral Sea basin since the middle of last century. The upstream part of Amu Darya River, as the main water source of Aral Sea, is almost entirely located in Tajikistan, thus, the development and utilization of Tajikistan water resources affect the whole Aral Sea basin. The author puts forward oriented-development of green energy under the overall framework of co-building Silk Road and Economic Belt, developing small hydro-power and dam-free hydro-power stations, standardized implementation of agricultural modernization in Central Asia, through high efficiency and water saving agriculture to achieve “returning water to sea”, to reverse drying trend of Aral Sea, to renovate ecological environment, resulting in simultaneous implementation of agricultural production and Aral Sea governance, simultaneous achievement of agricultural harvest and ecological environment improvement of Aral Sea basin. The article makes a scientific proof of reality and feasibility regarding the proposed methods. Green ecological environment and stable social environment will contribute to the sustainable development of Green Silk Road and Economic belt.…

Health Economics of Nutrition Intervention in Asia: Cost of Malnutrition.

2015-01-01

Asia has recorded the fastest economic growth in the world. However, some countries are still struggling with economic stagnation and poverty. Even in the emerging countries, there are economic disparities between urban and rural areas within a country. Reflecting the situations, nutritional issues in Asia came to be the antithetical situation of excess and insufficiency. The rate of overweight and obesity keeps increasing, especially in emerging countries. Meanwhile, underweight is still a critical problem in the region. Although the importance of nutrition is well recognized for social and economic development, it is difficult to identify the immediate outcome of nutrition interventions. Evidence-based decision-making is an important element of quality health care and efficiency and effectiveness are always key words. Along with enhanced attention to accountability and transparency of budget use in health services, attention to the economic evaluation of nutrition interventions has increased in recent years. In this symposium, we will review the current situation of nutritional issues and economic evaluation of nutrition interventions in Asia through experience of an international organization, the basis and trends for health care economics, and also efforts have been made in an Asian country. Discussion will be made about efficient and effective ways to evaluate projects/programmes for nutrition improvement.

Using wavelets to decompose the time frequency effects of monetary policy

NASA Astrophysics Data System (ADS)

Aguiar-Conraria, Luís; Azevedo, Nuno; Soares, Maria Joana

2008-05-01

Central banks have different objectives in the short and long run. Governments operate simultaneously at different timescales. Many economic processes are the result of the actions of several agents, who have different term objectives. Therefore, a macroeconomic time series is a combination of components operating on different frequencies. Several questions about economic time series are connected to the understanding of the behavior of key variables at different frequencies over time, but this type of information is difficult to uncover using pure time-domain or pure frequency-domain methods. To our knowledge, for the first time in an economic setup, we use cross-wavelet tools to show that the relation between monetary policy variables and macroeconomic variables has changed and evolved with time. These changes are not homogeneous across the different frequencies.

What is the economic burden of sports injuries?

PubMed

Öztürk, Selcen; Kılıç, Dilek

2013-01-01

Despite the health benefits of sports activities, sports injury and fear of injury are important barriers to participation in sport. The incidence, prevalence and type of sports injuries vary among men and women as well as age groups. It is usually difficult to examine these different aspects of sports injuries due to insufficient data. This study argues that sport injuries can be considered as an important economic burden in terms of the direct and indirect costs it bears. As a result, strong and effective strategies are needed to prevent sports injuries. Sports medicine has also been attracted increasing attention in recent years, particularly. In this article, the importance of sports injuries and their economic costs as well as the role of sport medicine as a prevention method for sports injuries were discussed.

Environment, health, and sustainable development: the role of economic instruments and policies.

PubMed Central

Warford, J. J.

1995-01-01

Recent years have seen considerable progress in integrating environmental concerns into the mainstream of development policy and planning. Economic instruments designed explicitly for environmental purposes may help to achieve cost-effective solutions, and generate public revenues. Macroeconomic and sectoral policies may impact heavily upon the environment, and there is much scope for policy reforms that are justified in both economic and environmental terms. Progress in this area has been much more rapid than in the case of health objectives, even though the rationale for environmental improvement is often ultimately related to human health and well-being. It is proposed that lessons from recent experience in the use of economic instruments and policies to achieve environmental objectives are highly relevant for the health sector, which should seek and encourage support for measures that requires consumer and producers of environmentally degrading products to pay for the economic and social costs of the damage resulting from their use. Policy reform at the macroeconomic or sectoral level may yield cost-effective solutions to some health problems, and may even bring about improvements in health status that involve no net cost at all. The countrywide impact of such policies indicate that health agencies, including WHO, should develop the capacity to understand how economic policies and the adjustment process impact upon human health, not only direct through the effect on incomes, but also indirectly, via changes in the natural environment. Ability to conduct rigorous health impact assessment of economic policy reform, which requires a multidisciplinary effort, is a necessary condition if health ministries are to maximize their effectiveness in influencing overall government economic policy.

Development based on carrying capacity. A strategy for environmental protection

USGS Publications Warehouse

Carey, D.I.

1993-01-01

Environmental degradation has accelerated in recent years because economic development activities have been inconsistent with a sustainable environment. In human ecology, the concept of 'carrying capacity' implies an optimum level of development and population size based on a complex of interacting factors - physical, institutional, social, and psychological. Development studies which have explicitly recognized carrying capacity have shown that this approach can be used to promote economic activities which are consistent with a sustainable social and physical environment. The concept of carrying capacity provides a framework for integrating physical, socioeconomic, and environmental systems into planning for a sustainable environment. ?? 1993.

OptiPhy, a technical-economic optimisation model for improving the management of plant protection practices in agriculture: a decision-support tool for controlling the toxicity risks related to pesticides.

PubMed

Mghirbi, Oussama; LE Grusse, Philippe; Fabre, Jacques; Mandart, Elisabeth; Bord, Jean-Paul

2017-03-01

The health, environmental and socio-economic issues related to the massive use of plant protection products are a concern for all the stakeholders involved in the agricultural sector. These stakeholders, including farmers and territorial actors, have expressed a need for decision-support tools for the management of diffuse pollution related to plant protection practices and their impacts. To meet the needs expressed by the public authorities and the territorial actors for such decision-support tools, we have developed a technical-economic model "OptiPhy" for risk mitigation based on indicators of pesticide toxicity risk to applicator health (IRSA) and to the environment (IRTE), under the constraint of suitable economic outcomes. This technical-economic optimisation model is based on linear programming techniques and offers various scenarios to help the different actors in choosing plant protection products, depending on their different levels of constraints and aspirations. The health and environmental risk indicators can be broken down into sub-indicators so that management can be tailored to the context. This model for technical-economic optimisation and management of plant protection practices can analyse scenarios for the reduction of pesticide-related risks by proposing combinations of substitution PPPs, according to criteria of efficiency, economic performance and vulnerability of the natural environment. The results of the scenarios obtained on real ITKs in different cropping systems show that it is possible to reduce the PPP pressure (TFI) and reduce toxicity risks to applicator health (IRSA) and to the environment (IRTE) by up to approximately 50 %.

The effect of medical malpractice liability on rate of referrals received by specialist physicians.

PubMed

Xu, Xiao; Spurr, Stephen J; Nan, Bin; Fendrick, A Mark

2013-10-01

Using nationally representative data from the United States, this paper analyzed the effect of a state’s medical malpractice environment on referral visits received by specialist physicians. The analytic sample included 12,839 ambulatory visits to specialist care doctors in office-based settings in the United States during 2003–2007. Whether the patient was referred for the visit was examined for its association with the state’s malpractice environment, assessed by the frequency and severity of paid medical malpractice claims, medical malpractice insurance premiums and an indicator for whether the state had a cap on non-economic damages. After accounting for potential confounders such as economic or professional incentives within practices, the analysis showed that statutory caps on non-economic damages of $250,000 were significantly associated with lower likelihood of a specialist receiving referrals, suggesting a potential impact of a state’s medical malpractice environment on physicians’ referral behavior.

An Energy-Economy-Environment Model for Simulating the Impacts of Socioeconomic Development on Energy and Environment

PubMed Central

Yao, Bo

2014-01-01

Many rapidly developing regions have begun to draw the attention of the world. Meanwhile, the energy and environmental issues associated with rapid economic growth have aroused widespread critical concern. Therefore, studying energy, economic, and environmental systems is of great importance. This study establishes a system dynamic model that covers multiple aspects of those systems, such as energy, economy, population, water pollution, air pollution, solid waste, and technology. The model designed here attempts to determine the impacts of socioeconomic development on the energy and environment of Tongzhou District in three scenarios: under current, planning, and sustainable conditions. The results reveal that energy shortages and water pollutions are very serious and are the key issues constraining future social and economic development. Solid waste emissions increase with population growth. The prediction results provide valuable insights into social advancement. PMID:24683332

They transfer the emotion, thought and backgrounds of social live to modern societies. As one of oldest settlements, Semarang Chinatown gives great influence toward Semarang City and has endless historical values. Old Chinese settlement is very thick with Chinese culture. It becomes the primary source of physical characteristics in this historical environment. However, physical and visual problems come along with the rapid economic growth in Semarang Chinatown. The old buildings that still remains in Semarang Chinatown are in deficient condition and losing their shapes. Moreover, modernization and economic growth influence the change building facade. Several old buildings were replaced with new buildings that tend not to adopt Chinese Architecture style. Consequently, it changes the value of the buildings and the value of the historical environment.

Health and ecological sustainability in the Arab world: a matter of survival.

2014-02-01

Discussions leading to the Rio+20 UN conference have emphasised the importance of sustainable development and the protection of the environment for future generations. The Arab world faces large-scale threats to its sustainable development and, most of all, to the viability and existence of the ecological systems for its human settlements. The dynamics of population change, ecological degradation, and resource scarcity, and development policies and practices, all occurring in complex and highly unstable geopolitical and economic environments, are fostering the poor prospects. In this report, we discuss the most pertinent population-environment-development dynamics in the Arab world, and the two-way interactions between these dynamics and health, on the basis of current data. We draw attention to trends that are relevant to health professionals and researchers, but emphasise that the dynamics generating these trends have implications that go well beyond health. We argue that the current discourse on health, population, and development in the Arab world has largely failed to convey a sense of urgency, when the survival of whole communities is at stake. The dismal ecological and development records of Arab countries over the past two decades call for new directions. We suggest that regional ecological integration around exchange of water, energy, food, and labour, though politically difficult to achieve, offers the best hope to improve the adaptive capacity of individual Arab nations. The transformative political changes taking place in the Arab world offer promise, indeed an imperative, for such renewal. We call on policy makers, researchers, practitioners, and international agencies to emphasise the urgency and take action. Copyright © 2014 Elsevier Ltd. All rights reserved.

The subsurface exploration of other planetary bodies can be used to unravel their geological history and assess their habitability. On Mars in particular, present-day habitable conditions may be restricted to the subsurface. Using a deep subsurface mine, we carried out a program of extraterrestrial analog research - MINe Analog Research (MINAR). MINAR aims to carry out the scientific study of the deep subsurface and test instrumentation designed for planetary surface exploration by investigating deep subsurface geology, whilst establishing the potential this technology has to be transferred into the mining industry. An integrated multi-instrument suite was used to investigate samples of representative evaporite minerals from a subsurface Permian evaporite sequence, in particular to assess mineral and elemental variations which provide small-scale regions of enhanced habitability. The instruments used were the Panoramic Camera emulator, Close-Up Imager, Raman spectrometer, Small Planetary Linear Impulse Tool, Ultrasonic drill and handheld X-ray diffraction (XRD). We present science results from the analog research and show that these instruments can be used to investigate in situ the geological context and mineralogical variations of a deep subsurface environment, and thus habitability, from millimetre to metre scales. We also show that these instruments are complementary. For example, the identification of primary evaporite minerals such as NaCl and KCl, which are difficult to detect by portable Raman spectrometers, can be accomplished with XRD. By contrast, Raman is highly effective at locating and detecting mineral inclusions in primary evaporite minerals. MINAR demonstrates the effective use of a deep subsurface environment for planetary instrument development, understanding the habitability of extreme deep subsurface environments on Earth and other planetary bodies, and advancing the use of space technology in economic mining.

Continental Rifts and Resources

NASA Astrophysics Data System (ADS)

Stein, Holly J.

2017-04-01

Nearly all resource-forming systems involve upward mobility of fluids and melts. In fact, one of the most effective means of chemically transforming the earth's crust can be readily observed in the rift environment. Imposition of rifting is based on deeper stresses that play out in the crust. At its most fundamental level, rifting transfers heat and fluids to the crust. Heat delivered by fluids aids both in transport of metal and maturation of hydrocarbons. The oxidizing capacity of fluids on their arrival in the deep crust, whether derived from old slabs, depleted upper mantle and/or deeper, more primitive mantle, is a fundamental part of the resource-forming equation. Oxidizing fluids transport some metals and breakdown kerogen, the precursor for oil. Reducing fluids transport a different array of metals. The tendency is to study the resource, not the precursor or the non-economic footprint. In doing so, we lose the opportunity to discover the involvement and significance of initiating processes; for example, externally derived fluids may produce widespread alteration in host rocks, a process that commonly precedes resource deposition. It is these processes that are ultimately the transferable knowledge for successful mineral and hydrocarbon exploration. Further limiting our understanding of process is the tendency to study large, highly complex, and economically successful ore-forming or petroleum systems. In order to understand their construction, however, it is necessary to put equal time toward understanding non-economic systems. It is the non-economic systems that often clearly preserve key processes. The large resource-forming systems are almost always characterized by multiple episodes of hydrothermal overprints, making it difficult if not impossible to clearly discern individual events. Understanding what geologic and geochemical features blocked or arrested the pathway to economic success or, even worse, caused loss of a resource, are critical to exploration. Central to resource-forming systems is the role and tempo of rifting, and the integrity of the geologic lid on the system. Whereas compressional subduction begets storage, extensional rifting is about release and upward migration. Comparison will be made of the older, Permian Oslo rift with minimal mineralization, and the younger, active Rio Grande rift in Colorado with extensive mineralization - discussing what we are missing in the way we study them.
