Full Text Available Workplace stress-related illness is a serious issue, and consequently many stress reduction methods have been investigated. Aromatherapy is especially for populations that work under high stress. Elementary school teachers are a high-stress working population in Taiwan. In this study, fifty-four elementary school teachers were recruited to evaluate aromatherapy performance on stress reduction. Bergamot essential oil was used for aromatherapy spray for 10 minutes. Blood pressure and autonomic nervous system parameters were recorded 5 minutes before and after the application of the aroma spray. Results showed that there were significant decreases in blood pressure, heart rate, LF power percentage, and LF/HF while there were increases in heart rate variability and HF power percentage (P<.001∗∗∗ after application of the aromatherapy spray. Further analysis was investigated by dividing subjects into three background variables (position variables, age variables, gender variables and anxiety degree groups. All parameters were significantly different for most subgroups, except for the substitute teachers and the light-anxiety group. Parasympathetic nervous system activation was measured after aromatherapy in this study. It encouraged further study for other stress working population by aromatherapy.

Full Text Available School-based assessment (SBA approach in evaluating students’ academic progress was officially introduced by the Ministry of Education Malaysia and implemented in-line with the Standards-based Primary School Curriculum, in stages starting in 2011 as part of Malaysia educational reform. Under this approach, teachers are given greater responsibility to design quality assessments that align with their students’ learning outcomes Hence, the objectives of this qualitative case study is focused on how the newly introduced assessment approach has benefits the teaching and learning process in evaluating Year 1 academic progress in three urban Chinese primary schools. Data collected from interviews involving three Year 1 Chinese language teachers found that teachers have very positive perspectives towards SBA and that overall both teachers and students have benefited from this system. However, there are also weaknesses that need to be acknowledged and improvements to be made. The findings implicate that for SBA to be successful, teachers need to be creative, using varying strategies in their teaching and exploiting repertoire of methods in assessing their students. Further study on the matter is inevitable in ensuring the success of SBA’s implementation.

Causal estimates of the benefits of increased schooling using U.S. state schooling laws as instruments typically rely on specifications which assume common trends across states in the factors affecting different birth cohorts. Differential changes across states during this period, such as relative school quality improvements, suggest that this assumption may fail to hold. Across a number of outcomes including wages, unemployment, and divorce, we find that statistically significant causal esti...

Recommender systems are present in many web applications to guide our choices. They increase sales and benefit sellers, but whether they benefit customers by providing relevant products is questionable. Here we introduce a model to examine the benefit of recommender systems for users, and found that recommendations from the system can be equivalent to random draws if one relies too strongly on the system. Nevertheless, with sufficient information about user preferences, recommendations become accurate and an abrupt transition to this accurate regime is observed for some algorithms. On the other hand, we found that a high accuracy evaluated by common accuracy metrics does not necessarily correspond to a high real accuracy nor a benefit for users, which serves as an alarm for operators and researchers of recommender systems. We tested our model with a real dataset and observed similar behaviors. Finally, a recommendation approach with improved accuracy is suggested. These results imply that recommender systems ...

Increasing wealth provides key motivation for students to forgo earnings and struggle through exams. But, as we argue in this paper, schooling generates many experiences and affects many dimensions of skill that, in turn, affect central aspects of individuals' lives. Schooling not only affects income, but also the degree to which one enjoys work, as well as one's likelihood of being unemployed. It leads individuals to make better decisions about health, marriage, and parenting. It also improv...

Full Text Available This article reports an analysis of the societal benefits and costs of recovering school dropouts. Successful recovery is defined by subsequent graduation from high school. The analysis is based on established estimates of the societal costs of dropping out including reduced government tax collections and higher social costs of welfare, healthcare, and crime. These potential costs are cast as benefits when a dropout is recovered. A large dropout recovery program provides the setting for the analysis. Rigorous attention is given to accurate estimation of the number of students who would not have graduated without the program in the year assessed and to the induced public costs of their continued education. Estimated benefits are weighed against the total annual public costs of the program, which operates in 65 school centers and commands an annual budget of about $70 million. The estimated benefit-cost ratio for this program is 3 to 1, a figure comparable to benefit-cost ratio estimates reported in studies of dropout prevention. The sensitivity of this conclusion to specific assumptions within the analysis is discussed.

Full Text Available IntroductionThe Safe Routes to School (SRTS program is designed to encourage active and safe transportation for children to school. This report examines the potential broader impact of these programs on communities within 0.5 mile (0.8 km of schools.MethodsWe used a geographic information system to generate estimates of the land area within 0.5 mile of public schools in 4 U.S. Census-defined categories: 37 large urban areas, 428 small urban areas, 1088 metropolitan counties (counties in metropolitan statistical areas excluding the urban areas, and 2048 nonmetropolitan counties. We estimated population at the county level or at the U.S. Census-defined urban-area level using data from the 2000 U.S. Census.ResultsIn large urban areas, 39.0% of the land area was within 0.5 mile of a public school, and in small urban areas, 26.5% of the land area was within 0.5 mile of a public school. An estimated 65.5 million people in urban areas could benefit from SRTS projects. In nonurban areas, 1% or less of land is within 0.5 mile of a public school.ConclusionResults suggest that SRTS projects in urban areas can improve the walking and bicycling environment for adults as well as for children, the target users. Investment in SRTS can contribute to increased physical activity among children and adults.
Champlin Refining and Chemicals Inc. is learning to optimize its catalyst systems for hydrotreating Venezuelan gas oils through a program of research, pilot plant testing, and commercial unit operation. The economic results of this project have been evaluated, and the benefits are most evident in improvements in product yields and qualities. The project has involved six commercial test runs, to date (Runs 10-15), with a seventh run planned. A summary of the different types of catalyst systems used in the test runs, and the catalyst philosophy that developed is given. Runs 10 and 11 used standard CoMo and NiMo catalysts for heavy gas oils hydrotreating. These catalysts had small pore sizes and suffered high deactivation rates because of metals contamination. When it was discovered that metals contamination was a problem, catalyst options were reviewed

Full Text Available The economic evolution of the last decades has entailed major changes concerning the Human Resource Management practices, in both private and budgetary sector of Romania. In order to maintain efficiency and market competitivity, a company must adapt to these changes by altering its human resource strategy since managers are encountering increasingly complex challenges as to attracting, motivating and retaining employees. Such an objective might be accomplished by elaborating a competitive system of employee compensation. This article focuses on the stage reached by the Human Resource Management in the compensation and benefits system of the private and budgetary sector. For the latter, we are focusing on the romanian system of higher education. This study demonstrates that the compensation and benefits system which is implemented in romanian universities is limited and can offer few opportunities as compared to the one implemented by private companies. It is worth saying that the legal system has a negative impact in this matter.

Full Text Available Electronic portfolios (e-portfolios have a positive impact on the learning process in a broad range of educational sectors and on learners of all ages. Yet because most e-portfolio-related studies are about their implementation in higher education, this type of research is less usual in the early childhood context, and there is no available research for Greek schools. This study aims to investigate the impact of e-portfolios on learning in a Greek primary school and to provide a resource regarding the educational benefits of e-portfolio in primary education. To do that, it employs the qualitative naturalistic method to collect data, along with mixed methods which were used to achieve triangulation and strengthen confidence in the outcomes. Participants in the research were fourteen 8-year-old pupils, and one of the researchers was their regular teacher. Data evaluation revealed that the e-portfolio added value in pupils’ learning, acted as a medium to involve parents, promoted pupils’ self-esteem, and was acknowledged as a valuable assessment tool and a challenge for the school community. Based on the experience of the e-portfolio implementation, the authors provide some suggestions that would possibly help researchers and primary school teachers adopt and develop e-portfolio systems in their particular settings.

Information systems have the potential to provide human benefit in a number of areas including: improvement of education, provision of social and other services to the public, health and well-being, work-life balance, environmental sustainability, democracy and self-determination, freedom, emancipation, poverty reduction, and social equity. However, most studies within Information Systems relate to a business context rather than directly to human benefit. When dealing with human benefit, system stakeholders may have different objectives regarding a system's use, its distribution, and the way r
All nations of the world depend on fossil fuels for their energy needs. However the obligation to reduce CO2 and other gaseous emissions in order to be in conformity with the Kyoto agreement is the reason behind which countries turn to non-polluting renewable energy sources. In this paper the pollution caused by the burning of fossil fuels is initially presented followed by a study on the environmental protection offered by the two most widely used renewable energy systems, i.e. solar water heating and solar space heating. The results presented in this paper show that by using solar energy, considerable amounts of greenhouse polluting gasses are avoided. For the case of a domestic water heating system, the saving, compared to a conventional system, is about 80% with electricity or Diesel backup and is about 75% with both electricity and Diesel backup. In the case of space heating and hot water system the saving is about 40%. It should be noted, however, that in the latter, much greater quantities of pollutant gasses are avoided. Additionally, all systems investigated give positive and very promising financial characteristics. With respect to life cycle assessment of the systems, the energy spent for manufacture and installation of the solar systems is recouped in about 1.2 years, whereas the payback time with respect to emissions produced from the embodied energy required for the manufacture and installation of the systems varies from a few months to 9.5 years according to the fuel and the particular pollutant considered. Moreover, due to the higher solar contribution, solar water heating systems have much shorter payback times than solar space heating systems. It can, therefore, be concluded that solar energy systems offer significant protection to the environment and should be employed whenever possible in order to achieve a sustainable future

Statutory Sick Pay, Jobseeker's Allowance, and Employment and Support Allowance are employment-related benefits in the United Kingdom (UK). They correspond to the Injury and Disease Allowance and Unemployment Insurance in Japan. The Government of the UK is determined to reform the benefit system to make it fairer and to improve financial work incentives, using the slogan "Welfare to Work". Against this background, the government of the UK united some non-contributory benefits into a new "Universal Credit" scheme, which started in April 2013. The labor policy was also reformed to improve work incentives, for example by abolishing the Flexible New Deal program and uniting all the "Welfare to Work" policies into the "Work Programme". These reforms are useful for reconsidering the labor and employment-related policy and benefit system of Japan. PMID:24334698

Full Text Available Increasing pressures to justify the value of music in schools over recent decades has led to the construction of three distinct areas of benefits: intrinsic (or musical benefits, extrinsic benefits related to academic and/or cognitive development, and extrinsic benefits related to psychosocial wellbeing. While some argue these categories have been useful for identifying specific areas of value and enabling targeted advocacy approaches, others have challenged this segmented approach to justification. While the most strident point of contention stems from the perception that categories which champion non-musical (extrinsic benefits have led to the devaluing of musical (intrinsic benefits, others dispute the categories themselves. Such arguments question the ability to separate what have been categorised as musical and non-musical elements, particularly in relation to social and political elements. This paper aims to tease out the practicality of these existing categories, and in doing so, challenge their robustness in both form and definition. The argument is made that current attempts to separate the value of school-based music into distinct categories is not only unclear, but also unhelpful in areas of advocacy. This argument rests on the premise that musical participation affords opportunities to enrich human experience in holistic and integrated ways, and that categorisation serves to preclude this unique value.
The study presents a methodology for quantitative assessment of the benefit yielded by the various engineered safety systems of a nuclear reactor containment from the standpoint of their capacity to protect the environment compared to their construction costs. The benefit is derived from an estimate of the possible damage from which the environment is protected, taking account of the probabilities of occurrence of malfunctions and accidents. For demonstration purposes, the methodology was applied to a 1 300-MWe PWR nuclear power station. The accident sequence considered was that of a major loss-of-coolant accident as investigated in detail in the German risk study. After determination of the benefits and cost/benefit ratio for the power plant and the containment systems as designed, the performance characteristics of three subsystems, the leakoff system, annulus exhaust air handling system and spray system, were varied. For this purpose, the parameters which describe these systems in the activity release programme were altered. The costs were simultaneously altered in order to take account of the performance divergences. By varying the performance of the individual sub-systems an optimization in design of these systems can be arrived at

The NASA Scientific and Technical Information Office was assigned the responsibility to examine the benefits of the utilization of electronic printing and duplicating systems throughout NASA Installations and Headquarters. The subject of this report is the documentation of the methodology used in justifying the acquisition of the most cost beneficial solution for the printing and duplicating requirements of a duplicating facility that is contemplating the acquisition of an electronic printing and duplicating system. Four alternatives are presented with each alternative costed out with its associated benefits. The methodology goes a step further than just a cost benefit analysis through its comparison of risks associated with each alternative, sensitivity to number of impressions and productivity gains on the selected alternative and finally the return on investment for the selected alternative. The report can be used in conjunction with the two earlier reports, NASA-TM-106242 and TM-106510 in guiding others in determining the cost effective duplicating alternative.

Recommender systems are present in many web applications to guide purchase choices. They increase sales and benefit sellers, but whether they benefit customers by providing relevant products remains less explored. While in many cases the recommended products are relevant to users, in other cases customers may be tempted to purchase the products only because they are recommended. Here we introduce a model to examine the benefit of recommender systems for users, and find that recommendations from the system can be equivalent to random draws if one always follows the recommendations and seldom purchases according to his or her own preference. Nevertheless, with sufficient information about user preferences, recommendations become accurate and an abrupt transition to this accurate regime is observed for some of the studied algorithms. On the other hand, we find that high estimated accuracy indicated by common accuracy metrics is not necessarily equivalent to high real accuracy in matching users with products. This disagreement between estimated and real accuracy serves as an alarm for operators and researchers who evaluate recommender systems merely with accuracy metrics. We tested our model with a real dataset and observed similar behaviors. Finally, a recommendation approach with improved accuracy is suggested. These results imply that recommender systems can benefit users, but the more frequently a user purchases the recommended products, the less relevant the recommended products are in matching user taste.

This is the first published qualitative assessment of a yoga program applied in a high school setting. This qualitative interview study was nested in a randomized, controlled trial studying the effects of a yoga program offered in place of a semester of physical education classes at a rural public high school. Student interviews were conducted after taking part in a semester of the yoga program. A formal passive consent with information about the qualitative study was sent home to parents/guardians of all students in the parent study before the interviews. Most students enjoyed the yoga classes and felt benefits. Negative reports of yoga practice were associated with gender as most males sensed peer pressure against practicing yoga. Despite this finding, most students wanted to continue yoga and would continue if it were offered in school. Positive reports include a greater kinesthetic awareness, which some students associated with a greater respect for the body and improved self-image. Among students reporting psychological benefits, many cited stress reduction; many used yoga to manage negative emotions; and some propagated more optimism. Most thought yoga could reduce interest in the use of drugs and alcohol and increase social cohesion with family and peers. We found that a yoga program is feasible in this sample of 9th and 10th graders, especially after benefits are perceived. We also found evidence that yoga may lead to emergent positive benefits in health behaviors not directly prescribed by the program. These results suggest that school-based yoga programs may be appropriate for promoting healthy behaviors at a societal level by focusing on the prevention of negative patterns during the adolescent transition.

This paper provides a comprehensive discussion on the benefits and technical challenges of controlling over-determined and over-actuated excitation systems ranging from 1-DOF to 6-DOF. The primary challenges of over-actuated systems result from the physical constraints imposed when the number of exciters exceeds the number of mechanical degree-of-freedom. This issue is less critical for electro-dynamic exciters which tend to be more compliant than servo-hydraulic exciters. To facilitate the t...

Public, private, government, and university stakeholders have focused increasing attention on children's environmental health. Priority areas have been healthy school environments including indoor air and environmental quality (IEQ); susceptibilities of children to environmental factors and associated illness; and, understanding exposure to biological, chemical, and physical agents. As multidisciplinary teams, studies and intervention demonstrations in California public schools were conducted. A common theme among them was a ''partnership,'' the collaboration between stakeholders from the aforementioned sectors. Federal funding and local bond measures for planning, maintenance, and modernization of school facilities have recently been authorized. Therefore, beneficial ''partnerships'' should be established to conduct needed IEQ, environmental health, and productivity research, development and demonstration. This commentary describes benefits for stakeholders and five strategies for future effective collaborations.

In light of the changes anticipated from this policy initiative, the purpose of this paper is to review and summarize the literature on the benefits and drawbacks of EHR systems. Much of the literature has focused on key EHR functionalities, including clinical decision support systems, computerized order entry systems, and health information exchange. Our paper describes the potential benefits of EHRs that include clinical outcomes (eg, improved quality, reduced medical errors, organizational outcomes (eg, financial and operational benefits, and societal outcomes (eg, improved ability to conduct research, improved population health, reduced costs. Despite these benefits, studies in the literature highlight drawbacks associated with EHRs, which include the high upfront acquisition costs, ongoing maintenance costs, and disruptions to workflows that contribute to temporary losses in productivity that are the result of learning a new system. Moreover, EHRs are associated with potential perceived privacy concerns among patients, which are further addressed legislatively in the HITECH Act. Overall, experts and policymakers believe that significant benefits to patients and society can be realized when EHRs are widely adopted and used in a “meaningful” way.Keywords: EHR, health information technology, HITECH, computerized order entry, health information exchange

In a short literature review, we have collected available knowledge on the potential benefits of urban agriculture, as part of local food systems, on climate change mitigation and adaptation. The effects of urban agriculture on climate change mitigation and adaptation depend on the type of agricultural practice (e.g. in greenhouses, in soil, in artificial substrates used resources) and the difference with previous land use (e.g. leading to an increase or decrease of sealed soil surface and gr...

Full Text Available BACKGROUND: With world food demand expected to double by 2050, identifying farming systems that benefit both agricultural production and biodiversity is a fundamentally important challenge for the 21(st century, but this has to be achieved in a sustainable way. Livestock grazing management directly influences both economic outputs and biodiversity on upland farms while contributing to potentially damaging greenhouse gas emissions, yet no study has attempted to address these impacts simultaneously. METHODS: Using a replicated, landscape-scale field experiment consisting of five management 'systems' we tested the effects of progressively altering elements within an upland farming system, viz i incorporating cattle grazing into an upland sheep system, ii integrating grazing of semi-natural rough grazing into a mixed grazing system based on improved pasture, iii altering the stocking ratio within a mixed grazing system, and iv replacing modern crossbred cattle with a traditional breed. We quantified the impacts on livestock productivity and numbers of birds and butterflies over four years. RESULTS CONCLUSION AND SIGNIFICANCE: We found that management systems incorporating mixed grazing with cattle improve livestock productivity and reduce methane emissions relative to sheep only systems. Systems that also included semi-natural rough grazing consistently supported more species of birds and butterflies, and it was possible to incorporate bouts of summer grazing of these pastures by cattle to meet habitat management prescriptions without compromising cattle performance overall. We found no evidence that the system incorporating a cattle breed popular as a conservation grazer was any better for bird and butterfly species richness than those based on a mainstream breed, yet methane emissions from such a system were predicted to be higher. We have demonstrated that mixed upland grazing systems not only improve livestock production, but also benefit
Since it has been completed in September 1996, the CTBT has been signed by 151 countries. Awaiting the 44 ratifications and entry into force, all of the nuclear powers have imposed unilateral moratoriums on nuclear test explosions. The end of these weapons development activities is often cited as the principal benefit of the CTBT. As the world begins to implement the Treaty, it has become clear that the development and operation of the CTBT verification system will provide a wide range of additional benefits if the data analysis products are available for dual-purpose applications. As this paper describes these could have economic and social implications, especially for countries with limited technical infrastructures. These involve, seismic monitoring, mineral exploration, scientific and technical training

This last summer we held the 5th Los Alamos Space Weather Summer School. This 8-week long program is designed for mid-career graduate students in related fields to come to LANL, receive lectures on space physics and space environment topics, and carry out a research project under the mentorship of LANL staff members. We accept typically 6-8 students to the program, with a strong applicant pool to choose from. This type of summer school program is relatively unique in the space physics community—there are several other summer schools but they are of shorter duration and do not include the mentor-research project aspect which builds a strong one-on-one connection between the summer student and his/her LANL mentor(s). From the LANL perspective, this program was intended to have several benefits including building collaborations between LANL staff and universities and recruitment of potential postdocs. From the student perspective, this program is not only an educational opportunity but a strong networking opportunity and a chance to enhance their professional skills and publication record. Students are permitted to work on projects directly related to their thesis or on projects in areas that are completely new to them. At the end of the summer school, the students also develop their presentation skills by preparing and giving AGU-style presentations on their research projects to the research group. Over the past five years the summer school has increased in popularity, and the feedback from the student participants has been very positive. Alumni of the program have continued collaborations with their mentors, resulting in publications and conference presentations, and one postdoc hire to date.
Westinghouse and KNFC are creating an upgraded core monitoring system by merging the BEACON system (best estimate analyzer for core operation-nuclear) and COLSS (core operating limit supervisory system) into an integrated product. Although both BEACON and COLSS are core monitoring systems that have been in operation at many plants for a number of years, they each have some features and capabilities that are not in the other. Therefore it has been decided to incorporate portions of COLSS into the beacon system to create an optional level to support core monitoring applications on selected combustion engineering (C-E) designed plants. This optional level in the beacon system will be called BEACON-COLSS and will allow the beacon system to monitor the LCO's and Tech Spec limits at CE plants that currently use COLSS. This paper will present the structure of the new core monitoring system and the benefits it achieves for current COLSS plants, i.e., CE plants in the US and KSNP (Korean standard nuclear power plant).

Full Text Available This paper discusses results from a small scale qualitative study of howprimary and secondary schools in three English local authorities respondedto the introduction and subsequent inspection of a legal duty to promotecommunity cohesion, following a series of ‘race’ riots in 2001 and theLondon bombings of 2005. The policy itself is seen as reflecting widerdiscourse and is shown as shifting in focus during the period it wasofficially inspected between 2008 and 2011. Schools respondeddifferentially to the duty and its inspection, with those in more multiculturalareas responding with higher degrees of confidence than those inmono-ethnic areas. Some policy ‘slippage’ is seen to occur in the wayschools re-framed the duty. Over time, most schools came to identify thecurriculum and the school’s ethos as the most important weapons in theirarmoury. Teachers embraced the new duty with different degrees ofenthusiasm – for some it confirmed the importance of holistic approachesto education which they felt had been sidelined in recent years, whilst othershowed various forms of resistance. Teachers encountered some subtle andchallenging professional dilemmas in the course of discharging the duty.Overall, the respondents in this study felt that the imposition of the dutyand its inspection had been more of a benefit than a burden.

Sustainable transportation infrastructure and travel policies aim to optimise the use of transportation systems to achieve economic and related social and environmental goals. To this end, a novel methodology based on life cycle assessment (LCA) has been developed in this study, with the aim of quantifying, in terms of CO2 emissions equivalent, the impact associated with different alternatives of waste collection systems in different urban typologies. This new approach is focussed on saving energy and raw materials and reducing the environmental impact associated with the waste collection system in urban areas, as well as allowing the design and planning of the best available technologies and most environment-friendly management. The methodology considers a large variety of variables from the point of view of sustainable urban transport such as the location and size of the urban area, the amount of solid waste generated, the level of social awareness on waste separation procedures, the distance between houses and waste collection points and the distance from the latter to the possible recovery plants and/or landfills, taking into account the material and energy recovery ratio within an integrated waste management system. As a case study, two different waste collection systems have been evaluated with this methodology in the ecocity Valdespartera located in Zaragoza, Spain, consisting of approximately 10,000 homes: (i) a system based on traditional truck transportation and manual collection, and (ii) a stationary vacuum waste collection system. Results show that, when operating at loads close to 100%, the stationary collection system has the best environmental performance in comparison with the conventional system. In contrast, when operating at load factors around 13% the environmental benefits in terms of net CO2-eq. emissions for the stationary collection system are around 60% lower in comparison with the conventional one.

Full Text Available In many countries, a higher education system which is based on welfare state practices prevails. In this system, the services are substantially provided by the state free of charge or at quite low prices. Since the services are financed by taxes, additional sources cannot be provided; and because of the fact that it doesn't entail a real cost benefit comparison by the users, it leads to inefficiency. From the early 80s on, there has been a tendency towards the marketing mechanisms in the provision of many public services such as education due to both strong theoretical and empirical reason, and the restrictions in public financing. Together with this tendency, the question of who benefits from education services is tried to be answered in order to discuss the stimulation of activities and additional resources on a reasonable base. The aim of this study is to determine whether it is the individual or the society who benefits from this public service at the higher education level by calculating private and social return rates through internal return rate technique which is one of the cost benefit analysis method. Findings from calculations have shown that the individual gains more than the society after a four-year university education.

Full Text Available Students in a new medical school were provided with laptops. This study explored the feasibility and educational benefits of mobile learning for two cohorts of students learning in two settings—university campus (first-year students and rural clinical placements (second-year students. Evaluation involved questionnaires, focus groups (faculty and students, and document analysis. Descriptive statistics were computed. Focus groups were audio-recorded, transcribed, and analysed thematically. Response rates for questionnaires exceeded 84%. Compared with second-year students, significantly more first-year students (60% took their laptops to campus daily (P=0.14 and used their laptops for more hours each day (P=0.031. All students used laptops most frequently to access the internet (85% and 97% and applications (Microsoft Word (80% and 61% and Microsoft PowerPoint (80% and 63%. Focus groups with students revealed appreciation for the laptops but frustration with the initial software image. Focus groups with faculty identified enthusiasm for mobile learning but acknowledged its limitations. Physical infrastructure and information technology support influenced mobile learning. Document analysis revealed significant costs and issues with maintenance. If adequately resourced, mobile learning through university-issued laptops would be feasible and have educational benefits, including equitable access to learning resources, when and where they are needed. However, barriers remain for full implementation.
Once the decision has been made to adopt an integrated medical information system (IMIS), there are a number of tissues to overcome. Users need to be aware of the impact the change will make on end users and be prepared to address issues that arise before they become problems. The purpose of this study is to investigate the benefits and unexpected problems encountered in the implementation of IMIS and to determine a useful framework for IMIS. The Yonsei University Dental Hospital is steadily constructing an IMIS. The vendor's PACS software, Piview STAR, supports transactions between workstations that are approved to integrating the health care enterprise (IHE) with security function. It is necessary to develop an excellent framework that is good for the patient, health care provider and information system vendors, in an expert, efficient, and cost-effective manner. The problems encountered with IMIS implementation were high initial investments, delay of EMR enforcement, underdevelopment of digital radiographic appliances and software and insufficient educational training for users. The clinical environments of dental IMIS is some different from the medical situation. The best way to overcome these differences is to establish a gold standard of dental IMIS integration, which estimates the cost payback. The IHE and its technical framework are good for the patient, the health care provider and all information systems vendors.

The transmission properties and coupling of solar light have been studied for glass core multimode fibers in order to verify their benefits for a solar fiber optic lighting system. The light transportation distance can be extended from 20 m with plastic fibers to over 100 m with the kind of glass fibers studied here. A high luminous flux, full visible spectrum, as well as an outstanding color rendering index (98) and correlated color temperature similar to the direct sun light outside have been obtained. Thus the outstanding quality of solar light transmitted through these fibers would improve the visibility of all kinds of objects compared to fluorescent and other artificial lighting. Annual relative lighting energy savings of 36% in Uppsala, Sweden, and 76% in Dubai were estimated in an office environment. The absolute savings can be doubled by using glass optical fibers, and are estimated to be in the order of 550 kWh/year in Sweden and 1160 kWh/year in Dubai for one system of only 0.159 m(2) total light collecting area. The savings are dependent on the fiber length, the daily usage time of the interior, the type of artificial lighting substituted, the system light output flux, and the available time of sunny weather at the geographic location.

More than 100 years after Edison's life changing discovery, 1.6-2 billion people around the globe still live without light, in dark and smoke filled homes. The remote and impoverished Himalayan villages of upper Humla, in north-west Nepal, belong to some of the 2.4 billion people who still depend on the use of traditional biomass for their daily energy services such as cooking, heating and light. These activities on open fireplaces have a direct chronic impact on the health and extremely low life expectancy of the women and children along with devastating deforestation. There is a strong relationship between prosperity and access to electricity. The more remote and isolated communities in Nepal generally live in great poverty. Eighty percent of Nepal's 28.5 million people live in rural areas, with around half of these so remote, that neither a road, nor the national grid is ever likely to reach them. While Nepal has no fossil fuel resources, it is a country that is rich in renewable energy resources such as hydropower and solar energy. These abundant and locally available renewable energy resources can be tapped into with appropriate locally developed technologies. Generating and storing electrical energy derived from these rich local energy resources can provide for appropriate and sustainable lighting, which brings potential health, education, social and economic benefits to the people who have previously lived in homes with excessive indoor air pollution. This paper describes the living conditions of some villages in upper Humla, and the possible benefits of a simple village electrification system that provides basic lighting for the homes and the consequent improvements in the living conditions of the villagers.

Full Text Available Introduction. Yoga is a holistic system of varied mind-body practices that can be used to improve mental and physical health and it has been utilized in a variety of contexts and situations. Educators and schools are looking to include yoga as a cost-effective, evidence-based component of urgently needed wellness programs for their students. Objectives. The primary goal of this study was to systematically examine the available literature for yoga interventions exclusively in school settings, exploring the evidence of yoga-based interventions on academic, cognitive, and psychosocial benefits. Methods. An extensive search was conducted for studies published between 1980 and October 31, 2014 (PubMed, PsycInfo, Embase, ISI, and the Cochrane Library. Effect size analysis, through standardized mean difference and Hedges’g, allowed for the comparison between experimental conditions. Results and Conclusions. Nine randomized control trials met criteria for inclusion in this review. Effect size was found for mood indicators, tension and anxiety in the POMS scale, self-esteem, and memory when the yoga groups were compared to control. Future research requires greater standardization and suitability of yoga interventions for children.

Full Text Available Physical Education teachers have been using some very classic team sports, like football, basketball, handball, volleyball, etc. for many years in order to develop their education work at school. As a consequence of this, the benefits of this kind of activities on Physical Education lessons have not been as notable as we mighthave expected, since, even if they are increasing, their development and application are still low. There are many and very varied new non-traditional sports that have emerged and extended across Spain in recent years. To mention an example, we could refer to a newly created non-traditional sport such as kin-ball. This sport wascreated for the purpose of achieving a way to combine several factors such as health, team-work and competitiveness. Three teams of four players each participate. This way, every player can participate to a great extent in all the moves of the match, for each of them must defend one area of their half in order to achieve a common objective. Besides, kin-ball helps to develop motor skills at school in an easy way; that is, coordination, balance and perception. There is a large variety of non-traditional games and sports that are similar to kin-ball, such as floorball, intercrosse, mazaball, tchoukball, ultimate, indiaca, shuttleball... All of them show many physical, psychic and social advantages, and can help us to make the Physical Education teaching-learning process more motivating, acquiring the recreational component that it showed some years ago and which hasnow disappeared

Children with auditory processing disorders (APD) were fitted with Phonak EduLink FM devices for home and classroom use. Baseline measures of the children with APD, prior to FM use, documented significantly lower speech-perception scores, evidence of decreased academic performance, and psychosocial problems in comparison to an age- and gender-matched control group. Repeated measures during the school year demonstrated speech-perception improvement in noisy classroom environments as well as significant academic and psychosocial benefits. Compared with the control group, the children with APD showed greater speech-perception advantage with FM technology. Notably, after prolonged FM use, even unaided (no FM device) speech-perception performance was improved in the children with APD, suggesting the possibility of fundamentally enhanced auditory system function.

Full Text Available The main purpose of the article is to research the effects of the integration of fine art content into mathematics on students at the primary school level. The theoretical part consists of the definition of arts integration into education, a discussion of the developmental process of creative mathematical thinking, an explanation of the position of art and mathematics in education today, and a summary of the benefits of arts integration and its positive effects on students. The empirical part reports on the findings of a pedagogical experiment involving two different ways of teaching fifth-grade students: the control group was taught mathematics in a traditional way, while the experimental group was taught with the integration of fine art content into the mathematics lessons. At the end of the teaching periods, four mathematics tests were administered in order to determine the difference in knowledge between the control group and the experimental group. The results of our study confirmed the hypotheses, as we found positive effects of fine art integration into mathematics, with the experimental group achieving higher marks in the mathematics tests than the control group. Our results are consistent with the findings of previous research and studies, which have demonstrated and confirmed that long-term participation in fine art activities offers advantages related to mathematical reasoning, such as intrinsic motivation, visual imagination and reflection on how to generate creative ideas.

In this paper, we discuss a number of ways to define and measure the affordability of energy consumption, and we examine the emergence of energy poverty in Italy in the period from 1998 to 2011. The paper examines the eligibility criteria for claiming the benefits available to support energy consumption for vulnerable families and it identifies the potential beneficiaries. The study assesses the appropriateness of the eligibility criteria by comparing the population targeted by the policy with the population actually facing affordability problems. A simulation exercise, using the hypothetical scenario most likely to result in energy benefits being made available, shows that, regardless of the affordability index adopted, the provision of state energy benefits has little impact on fuel poverty. - Highlights: • The paper provides a discussion of alternative measure of energy affordability. • We examine the emergence of fuel poverty in Italy from 1998 to 2011. • We assess the appropriateness of the Italian energy benefits eligibility criteria. • A simulation shows that the energy benefits have little impact on fuel poverty

Homeschooling through the public school system is a relatively new trend in education. This qualitative study focuses on the experiences of six families participating in public school homeschooling programs in British Columbia, Canada. (Parents were interviewed and the interviews were recorded with transcripts becoming the primary data for this research.) Parents' motivations for homeschooling through the public system, rather than homeschooling on their own, are centered on financial advanta...

Natural regulation of cabbage root flies works well in experimental organic cropping systems of white cabbage. Low input and complex organic systems benefit functional biodiversity by providing good living conditions to several groups of natural enemies. Intercropped green manure benefits large predators while small predatory beetles favour low input organic systems with bare soil between crop rows.

Allina Hospitals and Clinics is implementing an enterprise-wide information system with inpatient and ambulatory clinical documentation and orders, clinical decision support, and revenue cycle applications. Allina has adopted a rigorous approach to planning for and realizing the expected clinical and financial benefits from this investment. Allina's strategies include: Forming a benefits realization team with formal responsibility for analysis, education, facilitation, and measurement; Studying system design to consider requirements for benefits realization; Integrating cultural, organizational and process change plans with system implementation plans; Measuring benefits using a measurement framework that matches organizational reporting, enables multi-level sequential analysis and adjusts for bias in quantifying benefits; Assigning accountability for achieving benefits by matching every benefit with an individual and an operational group; system executives, hospital executives, and department managers are held accountable for benefits within their scope of responsibility, and expected financial benefits are part of their yearly budgets. This article describes Allina's approach for benefits planning, contrasting it with the typical provider's approach to benefits realization. It argues that this approach may greatly increase the likelihood of realizing the value of investments in integrated clinical and business IT PMID:15682677

The aim of the Global Earth Observation System of Systems (GEOSS) is to contribute to human wellbeing though improving the information available to decision-makers at all levels relating to human health and safety, protection of the global environment, the reduction of losses from natural disasters, and achieving sustainable development. Specifically, GEOSS proposes that better international co-operation in the collection, interpretation and sharing of Earth Observation information is an important and cost-effective mechanism for achieving this aim. While there is a widespread intuition that this proposition is correct, at some point the following question needs to be answered: how much additional investment in Earth Observation (and specifically, in its international integration) is enough? This leads directly to some challenging subsidiary questions, such as how can the benefits of Earth Observation be assessed? What are the incremental costs of GEOSS? Are there societal benefit areas where the return on investment is higher than in others? The Geo-Bene project has developed a `benefit chain' concept as a framework for addressing these questions. The basic idea is that an incremental improvement in the observing system (including its data collection, interpretation and information-sharing aspects) will result in an improvement in the quality of decisions based on that information. This will in turn lead to better societal outcomes, which have a value. This incremental value must be judged against the incremental cost of the improved observation system. Since in many cases there will be large uncertainties in the estimation of both the costs and the benefits, and it may not be possible to express one or both of them in monetary terms, we show how order-of-magnitude approaches and a qualitative understanding of the shape of the cost-benefit curves can help guide rational investment decision in Earth Observation systems.
Since 1990, expenditure on education has increased in Austria for every educational level. This has been the result of an extension of education beyond compulsory level as well as a shift from apprenticeships to vocational colleges. The other side of the coin of increasing costs are greater benefits to individuals, employers and society in general arising from a more skilled work force. A longer period devoted to education, and later entry into the workforce, does not only increase the earnin...

Full Text Available Given increased pressure on natural resources to deliver benefits, complex trade-offs and the regulation of behaviours in relation to benefits is of key concern. Behaviours that signify resistance to the rules according to which benefits are allocated prompt us to consider causal links and feedbacks between benefits, perceptions of benefits, meanings attached to the benefits, and the regulatory instruments that mediate the distribution of benefits. An understanding of how meanings influence the perception of benefits exposes the complexity inherent in how people perceive and allocate value to natural resource benefits. Meanings are personal, sometimes overlapping, context dependent and variable across space and time. A challenge in directing resource user behaviour in common pool resources is that the relationship between the resource and resource use is typically not interpreted to include the manner in which users associate resource benefits with meanings. We propose that collective ordering of meanings and associated rules help to direct behaviours and in doing so they contribute to the purposeful maintenance of desirable elements of a social-ecological system (i.e. robustness. Using an example, we illustrate how tensions around benefit sharing are rooted in the emergence and changing prioritisation of contexts and meanings over time. The importance of eliciting, ordering and sanctioning of meanings is emphasised. We conclude by discussing the implications for robustness and benefit sharing in social-ecological systems and we comment on the usefulness and limitations of the framework.

Access to an adequate supply of nutritious food has been recognized as a basic human right. However, many families across the UK face food insecurity, which is thought to be exacerbated during school holidays. To address this issue, some schools and community groups have chosen to roll out holiday clubs, though research into the effectiveness of such interventions is limited and no studies to date have evaluated holiday clubs being organized through schools. In an effort to address some of the limitations in the research literature, the current qualitative investigation utilized semi-structured interviews with staff involved in holiday clubs in school and community venues with the aim of gaging their views on the need for and benefits of holiday food provision in addition to potential areas for development. The investigation revealed that staff perceived many families to be facing food insecurity and isolation during the school holidays, which may be alleviated through holiday club provision. Holiday clubs were viewed as a valuable source of support for children and adults, providing food, activities, and learning experiences. Staff were keen to see them implemented on a wider scale in future but suggested some areas that require attention in any future development of such provision. Findings are discussed in relation to current research, policy, and practice surrounding the health and wellbeing of children and families. PMID:27597938

The complexity of accelerators is ever increasing and today it is typical that a large number of feedback loops are implemented, based on sophisticated models which describe the underlying physics. Despite this increased complexity the machine operators must still effectively monitor and supervise the desired behavior of the accelerator. This is not alone sufficient; additionally, the correct operation of the control system must also be verified. This is not always easy since the structure, design, and performance of the control system is usually not visualized and is often hidden to the operator. To better deal with this situation operators need some knowledge of the control system in order to react properly in the case of problems. In fact operators need mental models of the control system to recognize fault states and react appropriate to errors and misbehavior of both, the accelerator and the control system itself. Mental models gained only on infrequent experience can be imprecise or plain wrong in worst case. Control system training can provide a foundation to build better mental models and therefore help to enhance operator responses and machine availability. For a refinement of the mental model repeated experience is needed. This can be provided by training sessions at the real accelerator

Secretion systems are used by many bacterial pathogens for the delivery of virulence factors to the extracellular space or directly into host cells. They are attractive targets for the development of novel anti-virulence drugs as their inactivation would lead to pathogen attenuation or avirulence, followed by clearance of the bacteria by the immune system. This review will present the state of knowledge on the assembly and function of type II, type III and type IV secretion systems in Gram-negative bacteria focusing on insights provided by structural analyses of several key components. The suitability of transcription factors regulating the expression of secretion system components and of ATPases, lytic transglycosylases and protein assembly factors as drug targets will be discussed. Recent progress using innovative in vivo as well as in vitro screening strategies led to a first set of secretion system inhibitors with potential for further development as anti-infectives. The discovery of such inhibitors offers exciting and innovative opportunities to further develop these anti-virulence drugs into monotherapy or in combination with classical antibiotics. Bacterial growth per se would not be inhibited by such drugs so that the selection for mutations causing resistance could be reduced. Secretion system inhibitors may therefore avoid many of the problems associated with classical antibiotics and may constitute a valuable addition to our arsenal for the treatment of bacterial infections.

The goal of this study was to evaluate potential mental health benefits of yoga for adolescents in secondary school. Students were randomly assigned to either regular physical education classes or to 11 weeks of yoga sessions based upon the Yoga Ed program over a single semester. Students completed baseline and end-program self-report measures of mood, anxiety, perceived stress, resilience, and other mental health variables. Independent evaluation of individual outcome measures revealed that yoga participants showed statistically significant differences over time relative to controls on measures of anger control and fatigue/inertia. Most outcome measures exhibited a pattern of worsening in the control group over time, whereas changes in the yoga group over time were either minimal or showed slight improvements. These preliminary results suggest that implementation of yoga is acceptable and feasible in a secondary school setting and has the potential of playing a protective or preventive role in maintaining mental health.

In Korean Standard Nuclear Power Plant COLSS (Core Operating Limit Supervisory System) is used to monitor the DNBR Power Operating Limit (DNBRPOL) and Linear Heat Rate POL (KWPFPOL). Westinghouse and KNFC have developed an upgraded core monitoring system by combining the BEACONTM core monitoring system1 (Best Estimate Analyzer for Core Operation . Nuclear) and COLSS into an integrated product that is called BEACON-COLSS. BEACON-COLSS generates the 3-D power distribution corrected by the in-core detectors measurements. The 3-D core power distribution methodology in BEACON-COLSS is significantly better than the synthesis methodology in COLSS. BEACONCOLSS uses the CETOP-D2 thermal hydraulic code instead of CETOP-1. CETOP-D is a multi-channel thermal hydraulics code that will provide more accurate DNBR calculations than the DNBR calculators currently used in COLSS

The basic function of a modern power system is to satisfy the system load requirements as economically as possible and with a reasonable assurance of continuity and quality. The question of what is reasonable can be examined in terms of the costs and the worth to the consumer associated with providing an adequate supply. The process of preparing reliability worth estimates based on customer cost-of-interruption data is presented. These data can be derived for a particular utility service area and are used to determine appropriate customer damage functions. These indicators can be used with the basic loss of energy expectation (LOEE) index to obtain a factor that can be utilized to relate the customer losses to the worth of electric service reliability. This factor is designated as the interrupted energy assessment rate (IEAR). The developed IEAR values can be utilized in both generating capacity and composite generation and transmission system assessment. Methods for using these estimates in power system optimization at the planning stages are described and examples are used to illustrate the procedures. 106 refs., 77 figs., 64 tabs

In this research, we performed investigation and evaluation on cost-benefit, and made system construction of basic concept and conceptual design, prior to the system construction which performs (1) evaluation of cost-benefit of FBR development within the country, and (2) evaluation of cost-benefit for every item for R and D relating to the FBR development. As for the methods for cost-benefit, it shall be suitable to assume that success rate differs depending on the future scenario such as fuel prices and to employ discount rates, considering the point of long-term R and D investment. We also pointed out that establishment of discount rates is the biggest issue which influences the results of evaluation of cost-benefit then. When we grasp the effects, it is required to include the effects such as contribution to environmental benefits and energy security, or improvement of safety, other than real generation merits, as it is a public investment. Therefore we made investigations and developments on the way to understand the effects qualitatively. Based on the results, we made a proposal on application to the system, and then showed evaluation flows on the cost-benefit system. We also pointed out that it is a future task to be considered to establish fuel cost scenario or input data or parameters such as value of statistical life or CO2 reduction, as they are primary factors which influence evaluation results or system reliabilities.

The term "co-benefits" refers to positive outcomes accruing from a policy beyond the intended outcome, often or usually in other sectors. In the urban context, policies implemented in particular sectors (such as transport, energy or waste) often generate multiple co-benefits in other areas. Such benefits may be related to the reduction of local or global environmental impacts and also extend into the area of public health. A key to identifying and realising co-benefits is the adoption of systems approaches to understand inter-sectoral linkages and, in particular, the translation of this understanding to improved sector-specific and city governance. This paper reviews a range of policies which can yield health and climate co-benefits across different urban sectors and illustrates, through a series of cases, how taking a systems approach can lead to innovations in urban governance which aid the development of healthy and sustainable cities.

Studies conducted by NASA have shown that the operating range of the Shuttle can be substantially increased and cost of payload operation be decreased by making use of the Teleoperator Maneuvering System (TMS). The TMS is remotely controlled, free-flying, orbital mini-tug vehicle capable of performing a wide range of remote satellite services missions. It can operate out of the Shuttle cargo bay, from a space station, or on top of an upper stage like Centaur. For high energy missions up to and including geostationary orbit, the TMS propulsion stage will augment the Transfer Orbit Stage (TOS) recently proposed for commercial development in providing an effective low-cost second-stage system for delivering intermediate sized payloads to geosynchronous orbit (GEO). Attention is given to TMS capabilities for both long duration and short term orbital missions, taking into account also Space Station support operations.

Full Text Available Progress in diagnosis and treatment of movement disorders after neurological diseases like stroke, cerebral palsy, dystonia and at old age requires understanding of the altered capacity to adequately respond to physical obstacles in the environment. With posture and movement disorders, the control of muscles is hampered, resulting in aberrant force generation and improper impedance regulation. Understanding of this improper regulation not only requires the understanding of the role of the neural controller, but also attention for the 1 the interaction between the neural controller and the “plant”, comprising the biomechanical properties of the skeleton including the viscoelastic properties of the contractile (muscle and non-contractile (connective tissues: neuromechanics and 2 the closed loop nature of neural controller and biomechanical system in which cause and effect interact and are hence difficult to separate. Properties of the neural controller and the biomechanical system need to be addressed synchronously by the combination of haptic robotics, (closed loop system identification, and neuro-mechanical modelling. In this paper, we argue that assessment of neuromechanics in response to well defined environmental conditions and tasks may provide for key parameters to understand posture and movement disorders in neurological diseases and as biomarkers to increase accuracy of prediction models for functional outcome and effects of intervention.

This paper briefly reviews the historical evolution of paradigms that have been purported to characterise the clinical behaviour of breast cancer, with the intention of guiding treatment approaches. Results from randomised clinical trials and the explosion of knowledge in the area of cancer biology have discredited the monolithic paradigms that had dominated thinking about breast cancer in the past. Contemporary notions of breast cancer biology recognise that, although some cancers disseminate well before becoming clinically detectable, acquisition of a metastatic phenotype can occur at any point (or not at all) in the local evolution of the tumour. As a consequence, both systemic and timely local--regional therapies can be expected to influence disease dissemination and patient survival. This is consistent with results observed in clinical trials, overviews of which indicate that prevention of four local recurrences will, on the average, prevent one death from breast cancer. Optimisation of local-regional treatment is an important goal in breast cancer management. PMID:16605046

The literature reports that using Learning Recording Systems (LRS) is usually well received by students but that the pedagogical value of LRS in academic settings remains somewhat unclear. The primary aim of the current study is to document students' perceptions, actual pattern of usage, and impact of use of LRS on students' grade in a dental gross and neuroanatomy course. Other aims are to determine if students' learning preference correlated with final grades and to see if other factors like gender, age, overall academic score on the Dental Aptitude Test (DAT), lecture levels of difficulty, type of lecture, category of lecture, or teaching faculty could explain the impact, if any, of the use of LRS on the course final grade. No significant correlation was detected between the final grades and the variables studied except for a significant but modest correlation between final grades and the number of times the students accessed the lecture recordings (r=0.33 with P=0.01). Also, after adjusting for gender, age, learning style, and academic DAT, a significant interaction between auditory and average usage time was found for final grade (P=0.03). Students who classified themselves as auditory and who used the LRS on average for fewer than 10 minutes per access, scored an average final grade of 16.43 % higher than the nonauditory students using the LRS for the same amount of time per access. Based on these findings, implications for teaching are discussed and recommendations for use of LRS are proposed. PMID:23508921

The potential of Magnetic Suspension and Balance Systems (MSBS) to improve conventional wind tunnel testing techniques is discussed. Topics include: elimination of model geometry distortion and support interference to improve the measurement accuracy of aerodynamic coefficients; removal of testing restrictions due to supports; improved dynamic stability data; and stores separation testing. Substantial increases in wind tunnel productivity are anticipated due to the coalescence of these improvements. Specific improvements in testing methods for missiles, helicopters, fighter aircraft, twin fuselage transports and bombers, state separation, water tunnels, and automobiles are also forecast. In a more speculative vein, new wind tunnel test techniques are envisioned as a result of applying MSBS, including free-flight computer trajectories in the test section, pilot-in-the-loop and designer-in-the-loop testing, shipboard missile launch simulation, and optimization of hybrid hypersonic configurations. Also addressed are potential applications of MSBS to such diverse technologies as medical research and practice, industrial robotics, space weaponry, and ore processing in space.
Full Text Available Nowadays by emergence of novel educational technologies especially access to internet among the population in schools as well as their being influenced by global and non-native cultures, a sithuattion has appeared that makese educational system choose novel functions for itself corresponding to current needs. Selection and reaching novel functions in turn requires a new approach towards educational system. What introduces us novel educational systems as a modern educational technology rather than a challenge in an educational system is the effects of these technologies in employing teaching aids in classrooms with the aim of reinforcement of the students’ learning, which has been confirmed by numerous studies. Through elucidation of student-oriented approach as a modern approach in educational system, the present paper studies the shift from traditional education to modern education and explains the existing barriers as well as the studies carried out so far. We mention that the only way to reach student-oriented status and use potential talents of students in research is to utilize modern communication and information technologies in educational processes.
Since 2002 the AWI has been running the cooperation programme HIGHSEA with local schools. Each year 22-24 high school students are admitted. During their last three years of school they spend two days a week at the AWI and not at school. With this programme the AWI aims at providing solid science education not only for undergraduate or graduate students but also for high school students. For HIGHSEA-students four subjects (biology as a major, chemistry, math and English as accessory subjects) are combined and taught fully integrated. All of the curricular necessities of the four subjects have been rearranged in their temporal sequencing thus enabling a conceptual formulation of 3-4 major questions to be dealt with in the course of the three-year program. Students are taught by teachers of the cooperating schools as well as by scientists of the AWI. Close links and intense cooperation between teachers and scientists are the basis of fundamental changes in teaching and learning climate. We can clearly show that significantly more HIGHSEA alumni enter university, that HIGHSEA doubles the rate of students entering a science career and that with HIGHSEA alumni drop out rates are drastically reduced. Closely linking HIGHSEA with the AWI's graduate school POLMAR offers the opportunity for new approaches for both sides: high school students emerge in authentic scientific projects while PhD students gain teaching and supervising experience. For a period of six month during their second year HIGHSEA-students form smaller working groups (3-4 students). Each of these groups are in contact with one specific researcher, e. g. a PhD-student, at the AWI. The first task of the working group is to formulate a scientific question, albeit a small one in the field of "their" researcher. Within the given time HIGHSEA-students then work on their question and develop a final product to be delivered at the end of the six month. During their working period they are supervised by "their" Ph

Providing authentic research opportunities is a potent form of professional development that significantly impacts teaching practices. The University of Rhode Island's ARMADA Project (2003-2010) was funded by the National Science Foundation to create opportunities for teachers to work with marine science researchers and implement best-practices in their classrooms. In early 2009, I participated in a 6-week research experience that has changed how I teach and how I learn. On board the R/V Knorr, I worked as a sedimentologist with an international crew who used geophysics, geochemistry, microbiology and geology to understand the controls on and distribution of subseafloor microbial life in the equatorial Pacific. This experience has affected my educational practices in two ways: (1) motivating me to fill gaps in my own understanding of natural chemical processes, and (2) prioritizing authentic research opportunities for all students at my school. My participation in the ARMADA project underscored the importance of an interdisciplinary approach to research. The team of scientists exposed me to a variety of topics. Biochemistry and the role of redox reactions in biological systems were relatively new to me. Scientists encouraged me to dig deeper into the chemical systems that we were researching. Through self-study and coursework focusing on biogeochemical cycles, deriving energy through chemical processes, and atmospheric chemistry, I have learned much of the chemistry that I am now expected to teach in my courses. I continue to seek out opportunities to learn more and am currently volunteering at geochemistry laboratories at the USGS. My ARMADA research experience depended on teamwork. I learned that while the dynamics of research teams can be simplified if the teams are carefully designed, it is important that students need to learn to work with a variety of people in different situations. Therefore, in my courses, students work in different teams to design and

Full Text Available BACKGROUND Recently, theoretical studies have started a discussion on how the influx of immigrants affects the finances of the host country. OBJECTIVE This paper investigates whether admission of unskilled immigrants, whose children incur assimilation costs in order to become skilled workers, positively influences the net benefits for native residents and immigrants under a defined-benefit pension system (DB system.This paper also compared the results under a DB system with those under a defined-contribution pension system (DC system. METHODS This paper theoretically calculates the net benefits for native residents and immigrants under a DB system and compares the values between under a DB system and under a DC system. RESULTS The study has three main findings. (1 Under a DB system, native residents do not alwaysbecome net beneficiaries, even if the government admits an unlimited number of immigrants.This is unlike the analysis under the DC system. (2 The net benefits for native residents caused by permitting a small (large number of immigrants under the DB system becomes higher (lower than that under the DC system in certain practical situations. (3 Even if all residents who have the right to vote prefer to admit immigrants, there is a possibility that the net benefits for the native residents may be negative. CONCLUSIONS When admitting immigrants, the government must pay attention to the assimilation costs which offspring of immigrants have to pay and the future generation's right to vote becausethey are the main victims of the loss of benefits caused by the assimilation costs under DB system.

Full Text Available Introduction: Addressing systemic barriers experienced by low-income and minority students to accessing medical school, the University of Calgary's Cumming School of Medicine has spearheaded a year-round, mini-med school outreach initiative for Aboriginal students. Method: Junior and senior high school youth generally attend the half-day program in classes or camps of 15–25, breaking into small groups for multisession activities. Undergraduate medical education students mentor the youth in stations offering experiential lessons in physical examination, reading x-rays, and anatomy. All resources from the medical school are offered in-kind, including a pizza lunch at midday, whereas community partners organize transportation for the attendees. Results: Opening the medical school and its resources to the community offers great benefits to resource-constrained schools often limited in terms of science education resources. The model is also an effort to address challenges among the medical professions around attracting and retaining students from underserved populations. Conclusion: The prospect of increasing admission rates and successful completion of medical education among students from marginalized communities poses a real, though difficult-to-measure, possibility of increasing the workforce most likely to return to and work in such challenging contexts. A mini-medical school for Aboriginal youth highlights mutual, long-term benefit for diverse partners, encouraging medical educators and community-based science educators to explore the possibilities for deepening partnerships in their own regions.
Full Text Available Abstract Background The purpose was to: 1 perform a systematic review of studies examining the relation between physical activity, fitness, and health in school-aged children and youth, and 2 make recommendations based on the findings. Methods The systematic review was limited to 7 health indicators: high blood cholesterol, high blood pressure, the metabolic syndrome, obesity, low bone density, depression, and injuries. Literature searches were conducted using predefined keywords in 6 key databases. A total of 11,088 potential papers were identified. The abstracts and full-text articles of potentially relevant papers were screened to determine eligibility. Data was abstracted for 113 outcomes from the 86 eligible papers. The evidence was graded for each health outcome using established criteria based on the quantity and quality of studies and strength of effect. The volume, intensity, and type of physical activity were considered. Results Physical activity was associated with numerous health benefits. The dose-response relations observed in observational studies indicate that the more physical activity, the greater the health benefit. Results from experimental studies indicate that even modest amounts of physical activity can have health benefits in high-risk youngsters (e.g., obese. To achieve substantive health benefits, the physical activity should be of at least a moderate intensity. Vigorous intensity activities may provide even greater benefit. Aerobic-based activities had the greatest health benefit, other than for bone health, in which case high-impact weight bearing activities were required. Conclusion The following recommendations were made: 1 Children and youth 5-17 years of age should accumulate an average of at least 60 minutes per day and up to several hours of at least moderate intensity physical activity. Some of the health benefits can be achieved through an average of 30 minutes per day. [Level 2, Grade A]. 2 More vigorous

Full Text Available Transportation projects often require large initial investments and are expected to generate benefits extending far into the future. Thus, there is a need to compare benefits and costs that occur at different periods over time. Since money has a time value, the same amount of money at different time periods does not have the same value. Therefore, it is important to convert costs and benefits into equivalent values when conducting a Cost-Benefit Analysis (CBA. A special category of transportation projects is that of Intelligent Transport Systems (ITS. ITS comprise innovative solutions for travel demand and traffic management, and it is expected to play a key role in future sustainable urban development plans. Compared to other transportation projects, ITS have a lower initial investment. In this paper a framework based on a CBA is presented, assessing costs and benefits of three ITS projects implemented in Thessaloniki, Greece. The paper refers to future developments of ITS in the city of Thessaloniki. The examined systems have already been developed as demonstration systems in various regions throughout Europe. The benefits of the systems have been transferred and scaled up, so as to be in line with the specific characteristics of the Greek environment.

This paper proposed a net benefit value (NBV) model for cost-benefit evaluation of wastewater treatment and reuse projects, and attention was mainly paid to decentralized systems which are drawing wide interests all over the world especially in the water-deficient countries and regions. In the NBV model, all the factors related to project costs are monetary ones which can be calculated by using traditional methods, while many of the factors related to project benefits are non-monetary ones which need sophisticated methods for monetization. In this regard, the authors elaborated several methods for monetization of the benefits from wastewater discharge reduction, local environment improvement, and human health protection. The proposed model and methods were applied for the cost-benefit evaluation of a decentralized water reclamation and reuse project in a newly developed residential area in Xi'an, China. The system with dual-pipe collection and grey water treatment and reuse was found to be economically ineligible (NBV > 0) when all the treated water is reused for artificial pond replenishment, gardening and other non-potable purposes by taking into account the benefit of water saving. As environmental benefits are further considered, the economic advantage of the project is more significant. PMID:19403964
Full Text Available School Information System (SIS is an academic information system developed and implemented for a private school with a purpose to improve the efficiency of information retrieval for students, parents and school authority. One of the initial problems with SIS implementation was that it depended on the availability of computers and internet access. With slow internet connections, authentication process could be time consuming, especially if a website implements various external scripts to improve visual quality. Due to these reasons, as well as the fact that BlackBerry is one of the most popular smartphones in Indonesia, the developers decided to design a simpler but more powerful system that would resolve Blackberry Mobile SIS problems. The mobile SIS was designed, implemented and evaluated to provide a perfect solution for problems related to ease-of-access. The Mobile SIS facilitates students and parents in obtaining academic information anytime, anywhere and without the need for repeated authentication, via BlackBerry mobile connection. Mobile SIS also offers faster loading time relative to traditional website access. Using the push technology service, SIS could now provide students and parents in getting the latest information every time new information gets disseminated.
The development and operation planning of the Brazilian generation system has been realized in a coordinate way by several years, due to some organizations, where the main generating companies from the country take part. The benefit share of the system to each participant of the planning and integrated operation has aroused interest. This paper describes the alternate forms of cost benefit allocation, between the participant companies of a coordinate operation, in order to reach an adequateness of remuneration and incentives. It was analysed two proposal of benefit allocation for energy export/import contracts: share by generation value and share by marginal benefit, concluding that the second one represents the best way of contribution for the several factors that comprising a hydroelectric power plant (storage capacity, effective storage and turbine capacity).

The universal pensions schema has mandatory character and is guaranteed by the state. State is an administrator of the socialsecurity systems and sometimes as finance provider. In case of financial dis-equilibrium situations of the social insurance balance, the state grants loans to finance the deficit. As social security is a fundamental right of man, state has the responsibility to correlate benefits and ensure an adequate level of pensions. The correlation of benefits is in the first row l...

Full Text Available Enterprise Information Systems (EIS are collections of hardware, software, data, people and procedures that work together to manage organizational information resources, ultimately enhancing decision making, and strategic advantage. One of the key issues in the acquisition and utilization of EIS is the determination of the value of investment in such systems. Traditional capital budgeting models such as NPV, IRR, payback period, and profitability index focus mainly on quantifiable variables. However, there are many intangible variables that make the use of entirely quantitative measures incomplete and less inclusive. The high level of impact of information systems (IS on the entire organizational strategy and the information intensity of IS makes the use of such traditional methods less practicable. Attempts have been made to overcome these shortcomings by utilizing other techniques such as the real options model, goal programming model, knowledge value model and intelligent techniques. This paper proposes the adoption of a hybrid intelligent technique (fuzzy-expert system in carrying out a cost benefit analysis of EIS investment. The study takes high cognizance of intangible variables and vagueness / imprecision in human group decision making that requires a good level of consensus.

The marketization of education cannot serve as the guiding principle in constructing the modem school system,nor can it be directly transplanted from modem enterprise system.Because the modem school system is a kind of"educational institution"rather than an"economical institution",what it should focus on is not the ownership of property or the distinction of property,but on the core educational issue,that is,the students'development.Such a kind of modern school system requires that the government delegates power to schools to realize academic autonomy in schools (selfgovernance).

How can we make sustainable urban drainage systems (SUDS) smart? SUDS help us to manage surface water runoff from urban environments but they are capable of delivering much more. This paper looks beyond the water quantity and quality improvement functions of SUDS and investigates the multiple benefits that can be gained by implementing smart SUDS solutions. This work provides a new perspective, using methodologies not normally associated with SUDS research, to determine multiple benefits. The outputs of the work can potentially assist decision-makers, designer and planners in recognising the potential for multiple benefits that can be delivered by SUDS. The ecosystem services (ES) associated with a large redevelopment in Dundee, Scotland, UK, are identified and a public perception study together with public participatory geographical information system (PPGIS) methods was used to confirm the goods and benefits of the SUDS. The paper presents findings on the public perception of SUDS as they provide cultural benefits such as recreation, aesthetics and biodiversity. The results show that greenspace is important when choosing a location, and willingness to pay for greenspace is high in this area. This paper concludes that SUDS provide multi-functional benefits in relation to the ES, thereby justifying the cachet of being termed Smart SUDS. PMID:25633948

The contract change management (CCM) system is an online collaboration tool, which supports the contract change management process of new engineering contract (NEC) contract. It is currently used in practice on a wide range of civil, power, and building projects in the UK. The aim of this study is first to iden-tify the tangible and intangible benefits of the system through a user survey; then to develop a framework to measure these benefits. A questionnaire survey is conducted, which reveals that CCM can help project teams improve process effectiveness, reduce risk of process failures, and increase the compliance with NEC requirements. Subsequently, a spreadsheet tool is developed to allow CCM users to calculate the tan-gible cost savings as a result of using the system. For intangible benefits, a change management maturity model (CM3) is developed, which provides a measurement framework for assessing the improvement of a project team's capability in dealing with contract changes.
Since the school meal was first served in Korea in 1953, there have been many changes, particularly during the last decade. Recently, the representative features of the school meal system became free school meals for all pupils in elementary school and a nutrition teacher system in schools. These policies were suggested to implement more and more the educational role of the school meal. The rate of schools serving school meals reached 100% as of 2013, and 99.6% students eat a school meal each school day. Nutrition teachers were assigned to schools from 2007, and 4,704 (47.9%) nutrition teachers of all nutrition employees were employed in schools as of 2013. At present, various nutrition education materials are being development by local education offices and government agencies, and various education activities are being implemented spiritedly. The ultimate goal of school meals and school-based nutrition education are as follows: 1) improvement of the health of students; 2) promotion of the traditional Korean diet; and 3) extension of opportunities for a healthier dietary life.

This paper identifies potential risk reduction, cost savings and programmatic procurement benefits of a Mars Forward Lunar Surface System architecture that provides commonality or evolutionary development paths for lunar surface system elements applicable to Mars surface systems. The objective of this paper is to identify the potential benefits for incorporating a Mars Forward development strategy into the planned Project Constellation Lunar Surface System Architecture. The benefits include cost savings, technology readiness, and design validation of systems that would be applicable to lunar and Mars surface systems. The paper presents a survey of previous lunar and Mars surface systems design concepts and provides an assessment of previous conclusions concerning those systems in light of the current Project Constellation Exploration Architectures. The operational requirements for current Project Constellation lunar and Mars surface system elements are compared and evaluated to identify the potential risk reduction strategies that build on lunar surface systems to reduce the technical and programmatic risks for Mars exploration. Risk reduction for rapidly evolving technologies is achieved through systematic evolution of technologies and components based on Moore's Law superimposed on the typical NASA systems engineering project development "V-cycle" described in NASA NPR 7120.5. Risk reduction for established or slowly evolving technologies is achieved through a process called the Mars-Ready Platform strategy in which incremental improvements lead from the initial lunar surface system components to Mars-Ready technologies. The potential programmatic benefits of the Mars Forward strategy are provided in terms of the transition from the lunar exploration campaign to the Mars exploration campaign. By utilizing a sequential combined procurement strategy for lunar and Mars exploration surface systems, the overall budget wedges for exploration systems are reduced and the

Social media consist of powerful tools that impact not only communication but relationships among people, thus posing an inherent challenge to the traditional standards of who we are as dental educators and what we can expect of each other. This article examines how the world of social media has changed dental education. Its goal is to outline the complex issues that social media use presents for academic dental institutions and to examine these issues from personal, professional, and legal perspectives. After providing an update on social media, the article considers the advantages and risks associated with the use of social media at the interpersonal, professional, and institutional levels. Policies and legal issues of which academic dental institutions need to be aware from a compliance perspective are examined, along with considerations and resources needed to develop effective social media policies. The challenge facing dental educators is how to capitalize on the benefits that social media offer, while minimizing risks and complying with the various forms of legal constraint. PMID:26427774

It provides a tutorial introduction to recent advances in the mathematics of interacting systems, written by four leading experts in the field: V. Rivasseau illustrates the applications of constructive Quantum Field Theory to 2D interacting electrons and their relation to quantum gravity; R. Seiringer describes a proof of Bose-Einstein condensation in the Gross-Pitaevski limit and explains the effects of rotating traps and the emergence of lattices of quantized vortices; J.-P. Solovej gives an introduction to the theory of quantum Coulomb systems and to the functional analytic methods used to prove their thermodynamic stability; finally, T. Spencer explains the supersymmetric approach to Anderson localization and its relation to the theory of random matrices. All the lectures are characterized by their mathematical rigor combined with physical insights.
Comparative studies of social security systems have increasingly turned towards the use of replacement rates as measures of the level of benefits in different countries and therefore of the degree of social protection afforded by different welfare systems. The rationale for this is that replacement rates provide consistent measures of the relative generosity of payments and therefore indicate the ‘quality’ of social security systems. This paper reviews the use of replacement rates in comparis...

Analysis of benefits and costs associated with the operation of Computer-Aided Design and Drafting Systems (CADDS) are needed to derive economic justification for acquiring new systems, as well as to evaluate the performance of existing installations. In practice, however, such analyses are difficult to perform since most technical and economic advantages of CADDS are ΣirreduciblesΣ, i.e. cannot be readily translated into monetary terms. In this paper, a practical technique for economic analysis of CADDS in a drawing office environment is presented. A Σworst caseΣ approach is taken since increase in productivity of existing manpower is the only benefit considered, while all foreseen costs are taken into account. Methods of estimating benefits and costs are described. The procedure for performing the analysis is illustrated by a case study based on the drawing office activities at Atomic Energy of Canada Limited. (auth)
Full Text Available ISO9000-based Quality Management Systems(QMSs have been widely applied by manycontractors with a hope to improve the productquality and hence achieve the desiredobjective of client satisfaction. However,setting up and implementing an ISO9000-based QMS is not without cost. Unless thecontractors can benefit from such system, it isunlikely that the senior management ofcontracting firms will commit to implement anISO9000-based QMS. In this paper, the costsof setting up and implementing an ISO9000-based QMS are assessed through aquestionnaire survey. The results arecompared with the benefits attained by thecontractors. It is found that contractors couldbe benefited from the use of ISO9000-basedQMS both tangibly and intangibly. Based on amore conservative estimation of some tangiblebenefits, a basic operational cost-benefit ratioof one to three was derived from the results ofthe survey. Since the latest version ofISO9000 has been fully implemented for anumber of years, the perception of contractorson the benefits gained after theimplementation of ISO9001:2000 is alsoexamined in this paper.

Global Systems Science (GSS), a high school integrated interdisciplinary science project based at Lawrence Hall of Science at UC Berkeley, has collaborated with many organizations and institutions since its inception in the early 1990s. To start with, there were the federal agencies that made GSS possible: WESTGEC, NIGEC, NSF, and NASA. An NSF grant enabled the project to have teachers field test GSS in their classes and meet in summer institutes that resulted in GSS module dealing with climate change and related topics including energy use, ozone, loss of biodiversity, and ecosystem change. Interacting small and large systems naturally became an overarching theme. NASA grants and relationships with other NASA grantees in the NASA Innovations in Climate Education (NICE) program resulted in formation of Professional Learning Communities (PLCs) in the GSS Lifelines for High School Climate Change Education project. Teachers involved in that project participated in webinars with representatives of various climate change education resources, including SatCam, Detroit Climate Action Collaborative, Picture Post (UNH), Eyes on Earth, Earth Exploration Toolbook, My NASA Data, Digital Earth Watch (DEW), Alliance for Climate Education (ACE), the JPL Global Climate Change website, EOS-Webster (UNH), and Museum of the Earth at the Paleontological Research Institution. These webinars were recorded and are available at http://www.globalsystemsscience.org/lifelines/presentations. GSS course materials are available to teachers for free online at http://www.globalsystemsscience.org/

real-world problem is that resources are limited and technologies need to be prioritized to assure the resources are spent on technologies that provide the highest system level benefits. Toward that end, a systems approach is being taken to determine the benefits of technologies for the Spaceliner Investment Area. Technologies identified to be enabling will be funded. However, the other technologies will be funded based on their system's benefits. Since the final launch system concept will not be decided for many years, several vehicle concepts are being evaluated to determine technology benefits. Not only performance, but also cost and operability are being assessed. This will become an annual process to assess these technologies against their goals and the benefits to various launch systems concepts. The paper describes the system process, tools and concepts used to determine the technology benefits. Preliminary results will be presented along with the current technology investments that are being made by ASTP's Spaceliner Investment Area.

The School Health Portfolio System (SHPS), developed originally to evaluate the Florida Coordinated School Health Program Pilot Schools Project, offers a new and innovative system for planning and evaluating a coordinated school health program at the individual school level. The SHPS provides practitioners a detailed but easy-to-use system that enables schools to create new programs or modify existing programs across all eight components of the CSHP model, as well as administrative support critical to sustainability. The System comes packaged as a self-contained, notebook-style manual divided into 15 sections. It includes electronic templates of key documents to guide school teams in creating a customized portfolio, and a list of sample goals and artifacts that confirm achievement of a goal related to the school's coordinated school health program. An evaluation rubric provides a structured method to assess a program portfolio's contents, and the extent to which the contents document achievement of program goals. The rubric produces both a qualitative assessment, such as a narrative summary of program strengths and areas for improvement, and a quantitative assessment, such as a numerical score (0-100), letter grade (A-F), or 5-star system (*-*****). The physical structure, function, and scoring of the rubric depend on the method of assessment. The SHPS enables schools to set goals based on individual school needs, and incorporate CSHP goals into school improvement plans--a critical factor in sustainability and accountability. The System also offers teams the option of coordinating their efforts with CDC's School Health Index as a companion assessment measure. This article outlines the process a team would follow in developing a portfolio, and includes a sample assessment for the area of School Health Education. PMID:15656262
Prognostic health monitoring (PHM) is a proactive approach to monitor the ability of structures, systems, and components (SSCs) to withstand structural, thermal, and chemical loadings over the SSCs planned service lifespans. The current efforts to extend the operational license lifetime of the aging fleet of U.S. nuclear power plants from 40 to 60 years and beyond can benefit from a systematic application of PHM technology. Implementing a PHM system would strengthen the safety of nuclear power plants, reduce plant outage time, and reduce operation and maintenance costs. However, a nuclear power plant has thousands of SSCs, so implementing a PHM system that covers all SSCs requires careful planning and prioritization. This paper therefore focuses on a component selection that is based on the analysis of a component's failure probability, risk, and cost. Ultimately, the decision on component selection depend on the overall economical benefits arising from safety and operational considerations associated with implementing the PHM system.

In recent years, many countries with mandatory defined benefit pay-as-you-go (“PAYG”) systems have modified their systems to include individual accounts for financing retirement pensions. In most of these countries, a portion of the mandatory pension system’s contribution rate has been “carved-out”, and contributions earmarked by the carve-out are channeled into retirement accounts. Upon reaching retirement age, the contributions and accumulated interest in an individual’s account are used to...

Despite recent increases of psychosocial programs for pediatric chronic illness, few studies have explored their economic benefits. This study investigated the costs-benefits of a family systems-based, psychosocial intervention for pediatric chronic illness (MEND: Mastering Each New Direction). A quasi-prospective study compared the 12-month pre-post direct and indirect costs of 20 families. The total cost for program was estimated to $5,320. Families incurred $15,249 less in direct and $15,627 less in indirect costs after MEND. On average, medical expenses reduced by 86% in direct and indirect costs, for a cost-benefit ratio of 0.17. Therefore, for every dollar spent on the program, families and their third payers saved approximately $5.74. Implications for healthcare policy and reimbursements are discussed. PMID:27282311

Full Text Available This study presents a cost/worth analysis approach for optimal Placement and sizing of Combined Heat and Power (CHP systems. Particle Swarm Optimization (PSO as a powerful optimization technique is employed for optimization. Different benefits brought up by CHP systems are taken into account as a multi-objective decision making. Economical factors such as power and heat selling, reliability improvement, loss reduction, deferred upgrading investment and CHP costs are considered in this study. In order to incorporate stochastic nature of power system in this study, Monte-Carlo method is used to simulate the effect of uncertainty of loads and system on the optimal location and size of the CHPs in the network. This study conducts two separate case studies, 6-bus meshed test system and 14-bus radial test system to demonstrate economical feasibility for investment planning when cost and CHP benefits are taken into account. The impacts of considering different parameters such as the rate of load growth and interest are studied. Results indicate that the proposed methodology is capable of finding the best location and the optimal size of CHP that can cause improvement in network operation along with financial benefits
Dynamic electricity pricing can produce efficiency gains in the electricity sector and help achieve energy policy goals such as increasing electric system reliability and supporting renewable energy deployment. Retail electric companies can offer dynamic pricing to residential electricity customers via smart meter-enabled tariffs that proxy the cost to procure electricity on the wholesale market. Current investments in the smart metering necessary to implement dynamic tariffs show policy makers’ resolve for enabling responsive demand and realizing its benefits. However, despite these benefits and the potential bill savings these tariffs can offer, adoption among residential customers remains at low levels. Using a choice experiment approach, this paper seeks to determine whether disclosing the environmental and system benefits of dynamic tariffs to residential customers can increase adoption. Although sampling and design issues preclude wide generalization, we found that our environmentally conscious respondents reduced their required discount to switch to dynamic tariffs around 10% in response to higher awareness of environmental and system benefits. The perception that shifting usage is easy to do also had a significant impact, indicating the potential importance of enabling technology. Perhaps the targeted communication strategy employed by this study is one way to increase adoption and achieve policy goals. - Highlights: • We evaluate preferences for domestic dynamic electricity tariffs in the US and EU. • We use an online choice experiment approach with two dynamic tariff options. • People are more likely to switch if shown environmental and system benefits. • People are more likely to switch if they find shifting demand easy to do. • Our results imply the importance of targeted communication and enabling technology
Full Text Available This article proposes a quantitative risk assessment for security systems which have multiple protected assets and a risk-based benefit-cost analysis for decision makers. The proposed methodology consists of five phases: identification of assets, security unit and intrusion path, security unit effectiveness estimation, intrusion path effectiveness estimation, security system risk assessment and benefit-cost estimation. Key innovations in this methodology include its use of effectiveness entropy to measure the degree of uncertainty of a security system to complete a protection task, and the fact it measures risk like information theory measures the amount of information. A notional example is provided to demonstrate an application of the proposed methodology.
Full Text Available This paper describes the cost-benefit analysis of digital long-term preservation (LTP that was carried out in the context of the Finnish National Digital Library Project (NDL in 2010. The analysis was based on the assumption that as many as 200 archives, libraries, and museums will share an LTP system. The term ‘system’ shall be understood as encompassing not only information technology, but also human resources, organizational structures, policies and funding mechanisms. The cost analysis shows that an LTP system will incur, over the first 12 years, cumulative costs of €42 million, i.e. an average of €3.5 million per annum. Human resources and investments in information technology are the major cost factors. After the initial stages, the analysis predicts annual costs of circa €4 million. The analysis compared scenarios with and without a shared LTP system. The results indicate that a shared system will have remarkable benefits. At the development and implementation stages, a shared system shows an advantage of €30 million against the alternative scenario consisting of five independent LTP solutions. During the later stages, the advantage is estimated at €10 million per annum. The cumulative cost benefit over the first 12 years would amount to circa €100 million.
Highlights: • The energy policy was assessed using the system dynamics approach. • A life table approach was presented to estimate averted loss of life expectancy. • The mortality benefits estimated by VSL and VSLY are found to be similar. • Economic feasibility of the energy policy for climate change mitigation was presented. - Abstract: A novel Air Resource Co-benefits model was developed to estimate the social benefits of a Sustainable Energy Policy, involving both renewable energy (RE) and energy efficiency improvements (EEI). The costs and benefits of the policy during 2010–2030 were quantified. A system dynamics model was constructed to simulate the amount of energy saving under the scenario of promoting both RE and EEI. The life-cycle co-reductions of five criteria pollutants (PM10, SO2, NOx, CO, and ozone) and greenhouse gas are estimated by assuming coal fired as marginal electricity suppliers. Moreover, a concise life table approach was developed to estimate averted years of life lost (YOLL). The results showed that YOLL totaling 0.11–0.21 years (41–78 days) per capita, or premature deaths totaling 126,507–251,169, is expected to be averted during 2010–2030 under the RE plus EEI scenario. Specifically, because of the higher investment cost, the benefit-cost ratio of 1.9–2.1 under the EEI scenario is lower than the 7.2–7.9 under the RE scenario. This difference reveals that RE is more socially beneficial than EEI. The net benefit of the RE and EEI scenarios during 2010–2030 totaled approximately US$ 5,972–6,893 per person or US$ 170–190 per MW h. To summarize, this study presents a new approach to estimate averted YOLL, and finds that the health benefits can justify the compliance costs associated with the Sustainable Energy Policy

Full Text Available The present paper analyses the reliability and cost-benefit for a single unit system with scheduled maintenance and variation in demand. As Change in demand affects the production of system also, hence sometimes, the system needs to be shut down when the number of produces are in excess as compared to those demanded. Revenue in case of both types of up states i.e., when demand is greater than or equal to production and when demand is less than production have also been taken under consideration while carrying out the cost-benefit analysis. The loss incurred to the system when it is kept shut down due to less demand has also been taken into account. Optimized reliability indices of the system effectiveness are estimated numerically using semi-Markov processes and regenerative point technique. Expression for the expected profit is obtained after obtaining various measures of system effectiveness. We can conclude that cut off points for various rates/probabilities/revenue per unit up time/costs can be obtained which help in deciding the upper/lower acceptable values of rates/costs so that the system is profitable.

An audience response systems (ARS) allows students to respond to multiple choice questions using remote control devices. Once the feedback is collected and displayed, the teacher and students discuss misconceptions and difficulties experienced. ARSs have been extremely popular and effective in higher education science classrooms, although almost no research has been done at the secondary school level. The purpose of this study was to conduct a detailed formative analysis of the benefits, challenges, and use of ARSs from the perspective of 213 secondary school science students. Perceived benefits were increased student involvement (engagement, participation, and attention) and effective formative assessment of student understanding. Perceived challenges included decreased student involvement and learning when ARSs were used for summative assessment, occasional technological malfunctions, resistance to using a new method of learning, and increased stress due to time constraints when responding to questions. Finally, students rated the use of ARSs significantly higher when it was used for formative as opposed to summative assessment.

Global Systems Science (GSS), a high school integrated interdisciplinary science project based at Lawrence Hall of Science at UC Berkeley, began in the early 1990s as a single book "Planet at Risk" which was only about climate change. Federal grants enabled the project to enlist about 150 teachers to field test materials in their classes and then meeting in summer institutes to share results and effect changes. The result was a series of smaller modules dealing not only with climate change, but other related topics including energy flow, energy use, ozone, loss of biodiversity, and ecosystem change. Other relevant societal issues have also been incorporated including economics, psychology and sociology. The course has many investigations/activities for student to pursue, interviews with scientists working in specific areas of research, and historical contexts. The interconnectedness of a myriad of small and large systems became an overarching theme of the resulting course materials which are now available to teachers for free online at http://www.globalsystemsscience.org/

To meet its objective of assisting the U.S. aviation industry with the technological challenges of the future, NASA must identify research areas that have the greatest potential for improving the operation of the air transportation system. Therefore, NASA is developing the ability to evaluate the potential impact of various advanced technologies. By thoroughly understanding the economic impact of advanced aviation technologies and by evaluating how the new technologies will be used in the integrated aviation system, NASA aims to balance its aeronautical research program and help speed the introduction of high-leverage technologies. To meet these objectives, NASA is building the Aviation System Analysis Capability (ASAC). NASA envisions ASAC primarily as a process for understanding and evaluating the impact of advanced aviation technologies on the U.S. economy. ASAC consists of a diverse collection of models and databases used by analysts and other individuals from the public and private sectors brought together to work on issues of common interest to organizations in the aviation community. ASAC also will be a resource available to the aviation community to analyze; inform; and assist scientists, engineers, analysts, and program managers in their daily work. The ASAC differs from previous NASA modeling efforts in that the economic behavior of buyers and sellers in the air transportation and aviation industries is central to its conception. Commercial air carriers, in particular, are an important stakeholder in this community. Therefore, to fully evaluate the implications of advanced aviation technologies, ASAC requires a flexible financial analysis tool that credibly links the technology of flight with the financial performance of commercial air carriers. By linking technical and financial information, NASA ensures that its technology programs will continue to benefit the user community. In addition, the analysis tool must be capable of being incorporated into the

The Digital Document Storage (DDS)/Pilot Production System (PPS) will provide cost effective electronic document storage, retrieval, hard copy reproduction, and remote access for users of NASA Technical Reports. The DDS/PPS will result in major benefits, such as improved document reproduction quality within a shorter time frame than is currently possible. In addition, the DDS/PPS will provide an important strategic value through the construction of a digital document archive. It is highly recommended that NASA proceed with the DDS Prototype System and a rapid prototyping development methodology in order to validate recent working assumptions upon which the success of the DDS/PPS is dependent.
Full Text Available This paper presents a methodology to assess agricultural-to-hydropower water transfers in water resources systems where irrigation crop production and hydropower generation are the main economic activities. In many countries, water for crop irrigation is often considered as a static asset: irrigation water is usually allocated by a system of limited annual rights to use a prescribed volume of water. The opportunity cost (forgone benefits of this static management approach may be important in river basins where large irrigation areas are present in the upstream reaches. Temporary reallocation of some (or all of the irrigation water downstream to consumptive and/or non-consumptive users can increase the social benefits if the sum of the downstream productivities exceeds those of the upstream farmers whose entitlements are curtailed. However, such a dynamic allocation process will be socially acceptable if upstream farmers are compensated for increasing the availability of water downstream. This paper also presents a methodology to derive the individual contribution of downstream non-consumptive users, i.e. hydropower plants, to the financial compensation of upstream farmers. This dynamic management approach is illustrated with a cascade of multipurpose reservoirs in the Euphrates river basin. The analysis of simulation results reveals that, on average, the annual benefits obtained with the dynamic allocation process are 6% higher that those derived from a static allocation.

Schools have been identified as ideal settings for health promotion (HP) among children, adolescents and school staff. Most European countries have established strategies to implement HP into their school system, however, little is known about these national strategies and how effective they have been. School HP implementation concerns processes of adoption, adaptation and operation of a complex intervention into a complex setting. This study analyses the processes that have led to school HP implementation in Scotland from the 1980s until now to identify key factors which facilitated and supported effective implementation. In the tradition of case-study research, 14 interviews with representatives of national and local organizations involved in school health, as well as with school staff were conducted. Furthermore, policy documents, reports and guidelines were collected. The data were analysed following a Grounded Theory approach. Four phases of school HP implementation into the Scottish school system were identified: (i) getting started (1980s-1998), (ii) political will and strategic vision (1999-2001), (iii) national leadership (2002-2008), and (iv) integration and embedding into education system (2008-ongoing). Throughout the phases political will and committed actors, the strategy/tradition to give power to the local authorities and individual schools, and the establishment of partnerships and ownership have supported implementation. Scotland is an interesting case giving important insights into the ways and possibilities of negotiating an interdisciplinary and cross-sectoral theme such as HP in schools. Further research concerning different political systems and national implementation processes is important to widen the understanding of national implementation strategies of school HP. PMID:23135795

This study estimated the health, energy, and economic benefits of an economizer ventilation control system that increases outside air supply during mild weather to save energy. A model of the influence of ventilation rate on airborne transmission of respiratory illnesses was used to extend the limited data relating ventilation rate with illness and sick leave. An energy simulation model calculated ventilation rates and energy use versus time for an office building in Washington, D.C. with fixed minimum outdoor air supply rates, with and without an economizer. Sick leave rates were estimated with the disease transmission model. In the modeled 72-person office building, our analyses indicate that the economizer reduces energy costs by approximately $2000 and, in addition, reduces sick leave. The annual financial benefit of the decrease in sick leave is estimated to be between $6,000 and $16,000. This modeling suggests that economizers are much more cost effective than currently recognized.

This thesis provides a cost to benefit analysis of the proposed next generation of distribution systems- the Future Renewable Electric Energy Distribution Management (FREEDM) system. With the increasing penetration of renewable energy sources onto the grid, it becomes necessary to have an infrastructure that allows for easy integration of these resources coupled with features like enhanced reliability of the system and fast protection from faults. The Solid State Transformer (SST) and the Fault Isolation Device (FID) make for the core of the FREEDM system and have huge investment costs. Some key features of the FREEDM system include improved power flow control, compact design and unity power factor operation. Customers may observe a reduction in the electricity bill by a certain fraction for using renewable sources of generation. There is also a possibility of huge subsidies given to encourage use of renewable energy. This thesis is an attempt to quantify the benefits offered by the FREEDM system in monetary terms and to calculate the time in years required to gain a return on investments made. The elevated cost of FIDs needs to be justified by the advantages they offer. The result of different rates of interest and how they influence the payback period is also studied. The payback periods calculated are observed for viability. A comparison is made between the active power losses on a certain distribution feeder that makes use of distribution level magnetic transformers versus one that makes use of SSTs. The reduction in the annual active power losses in the case of the feeder using SSTs is translated onto annual savings in terms of cost when compared to the conventional case with magnetic transformers. Since the FREEDM system encourages operation at unity power factor, the need for installing capacitor banks for improving the power factor is eliminated and this reflects in savings in terms of cost. The FREEDM system offers enhanced reliability when compared to a
Interest in electrical energy storage systems is increasing as the opportunities for their application become more compelling in an industry with a back-drop of ageing assets, increasing distributed generation and a desire to transform networks into Smart Grids. A field trial of an energy storage system designed and built by ABB is taking place on a section of 11 kV distribution network operated by EDF Energy Networks in Great Britain. This paper reports on the findings from simulation software developed at Durham University that evaluates the benefits brought by operating an energy storage system in response to multiple events on multiple networks. The tool manages the allocation of a finite energy resource to achieve the most beneficial shared operation across two adjacent areas of distribution network. Simulations account for the key energy storage system parameters of capacity and power rating. Results for events requiring voltage control and power flow management show how the choice of operating strategy influences the benefits achieved. The wider implications of these results are discussed to provide an assessment of the role of electrical energy storage systems in future Smart Grids.
