    2011-01-01

    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.

  4. Do recommender systems benefit users?

    CERN Document Server

    Yeung, Chi Ho

    2015-01-01

    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 ...

  7. Can the provision of breakfast benefit school performance?

    Science.gov (United States)

    Grantham-McGregor, Sally

    2005-06-01

    Studies of an association between school performance (enrollment, attendance, achievement, classroom behavior, and school drop-out) and nutritional status are discussed and the evidence of an effect of school meals evaluated. Many studies have shown associations between hunger, poor dietary intakes, stunting, underweight, and poor school performance after controlling for socioeconomic conditions. However, it remains possible that unmeasured socioeconomic variables could explain the relationship. Rigorous short-term studies of missing breakfast have generally found detrimental effects on children's cognition whereas studies of providing breakfast have shown benefits particularly in malnourished children. Classroom conditions may modify the effects of breakfast on behavior. There are extremely few longer term studies of the effects of giving school meals. Nearly all involved breakfast and very few had randomized controlled designs. Studies comparing participants with non-participants or comparing matched schools have found benefits (but bias due to self-selection) of receiving breakfast; inadequate matching of schools also remains possible. One longer term randomized controlled trial found benefits associated with attendance and arithmetic performance. In conclusion, most studies of giving breakfast have found benefits to school performance but many had serious design problems, were short-term, and were not conducted in the poorest countries. In order to advise policy makers correctly, there is an urgent need to run long-term randomized controlled trials of giving school meals in poor countries and to determine the effects of age and nutrition status of the children, the quality of the school, and the timing of the meal. The special needs of orphans should also be considered.

  8. The Societal Benefits and Costs of School Dropout Recovery

    Directory of Open Access Journals (Sweden)

    James S. Catterall

    2011-01-01

    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.

    2016-07-01

    Full Text Available Benefit analysis of emergency standby system combined with absorption chiller promoted to cogeneration system is introduced. Economic evaluations of such upgraded projects play a major part in the decisions made by investors. Time-of-use rate structure, fuel cost and system constraints are taken into account in the evaluation. Therefore, the problem is formulated as a mixed-integer programming problem. Using two-stage methodology and modified mixed-integer programming technique, a novel algorithm is developed and introduced here to solve the nonlinear optimization problem. The net present value (NPV method is used to evaluate the annual benefits and years of payback for the cogeneration system. The results indicate that upgrading standby generators to cogeneration systems is profitable and should be encouraged, especially for those utilities with insufficient spinning reserves, and moreover, for those having difficulty constructing new power plants.

  16. The Compensation and Benefits System: Private Companies vs. Budgetary System

    Directory of Open Access Journals (Sweden)

    Aldea Bogdan

    2015-12-01

    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.

  18. Introducing E-portfolio Use to Primary School Pupils: Response, Benefits and Challenges

    Directory of Open Access Journals (Sweden)

    Dimitra Theodosiadou

    2015-03-01

    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.

  19. Injury prevention among friends: the benefits of school connectedness.

    Chapman, R L; Buckley, L; Reveruzzi, B; Sheehan, M

    2014-08-01

    Unsafe road behaviors, violence and alcohol use, are primary contributors to adolescent injury. Research suggests that adolescents look out for their friends and engage in protective behavior to reduce others' risk-taking and that school connectedness is associated with reduced injury-risks. This study examined the role of school connectedness in willingness to protect and prevent friends from involvement in alcohol use, fights and unlicensed driving. Surveys were completed at two time points, six months apart, by 545 13-14 year olds from seven Australian high schools. Females were significantly more likely than males to report willingness to protect their friends. School connectedness significantly and positively predicted willingness to protect across all three injury-risk behaviors, after accounting for sex and own involvement in injury-risk behaviors. School connectedness may therefore be an important factor to target in school-based prevention programs, both to reduce adolescents' own injury-risk behavior and to increase injury prevention among friends.

    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

  8. Environmental benefits of domestic solar energy systems

    2004-11-01

    All nations of the world depend on fossil fuels for their energy needs. However the obligation to reduce CO{sub 2} 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 gases 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 systems the saving is about 40%. It should be noted, however, that in the latter, much greater quantities of pollutant gases 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. (Author)

  9. Perceived Benefits of Yoga among Urban School Students: A Qualitative Analysis

    2016-01-01

    Full Text Available This study reports on the findings of a qualitative evaluation of a yoga intervention program for urban middle and high school youth in New York City public and charter schools. Six focus groups were conducted with students who participated in a year-long yoga program to determine their perceptions of mental and physical benefits as well as barriers and challenges. Results show that students perceived the benefits of yoga as increased self-regulation, mindfulness, self-esteem, physical conditioning, academic performance, and stress reduction. Barriers and challenges for a yoga practice include lack of time and space. The extent to which the benefits experienced are interrelated to one another is discussed. Suggestions for future research and school-based programming are also offered.

    2015-12-01

    Full Text Available The purpose of this study was to examine the benefits of physical exercise among secondary school students. Participants in the study were 251 students (120 boys and 131 girls attending three public secondary schools in the Hlanganani rural area of South Africa. A validated questionnaire was used to collect data. Results of this study indicated that students exercised to be with their friends, to be physically attractive and compete with others. The findings of this study have practical implications for promoting participation in physical activity among students in rural schools. In an effort to promote physical activity participation, schools should be provided with quality sports infrastructure and funding so that they can implement school sport programmes. Finally, the teaching of physical education should be emphasised in schools as it is the cornerstone for children’s involvement in physical activity.

    2010-03-01

    Full Text Available While research has been conducted concerning the effects of school-based mentoring on atrisk students, limited work has focused on the volunteer mentors. This study examined the motivations of adult volunteers and the benefits of their participation in a six-month,school-based mentoring program. A total of 31 volunteers completed adapted versions of the Volunteer Functions Inventory and a post-survey as part of a program in which they mentored at-risk elementary school students. Volunteers were more satisfied with theirmentoring experience when their perceived benefits matched their initial motivations, though this did not seem to impact their intentions to mentor again in the future. Volunteers’ motivations tended toward expressing important values or gaining greaterunderstanding, though some younger volunteers were also motivated to gain career-related experience. Implications for school-based mentoring programs are addressed.

    Schooling can provide fish with a number of behavioural and ecological advantages, including increased food supply and reduced predator risk. Previous work suggests that fish swimming using body and caudal fin locomotion may also experience energetic advantages when trailing behind neighbours...... significantly higher for schooling individuals swimming in the front of a school relative to those swimming in the back, with trailing individuals benefiting from a 14.9 +/- 3.2% reduction in fin beat frequency (mean +/- SE). Trailing fish were estimated to benefit from a 25.6% reduction in oxygen consumption...... oxygen consumption in leaders vs. solitary fish, we estimated that for an energetic advantage to occur in a school of striped surfperch as a whole, more than 78% of the individuals need to be in trailing positions, which is likely to be a common occurrence based on previous observations of other...

    Villarreal, Brandilynn J; Heckhausen, Jutta; Lessard, Jared; Greenberger, Ellen; Chen, Chuansheng

    2015-12-01

    High school students with high long-term educational expectations attain higher levels of education than those with lower expectations. Less studied is the role of students' short-term college enrollment expectations for the year after high school graduation. The purpose of the current study was to examine the costs and benefits of ambitious short-term expectations and the impact of falling short of these expectations on mental health, motivation, and educational outcomes. Over 1000 youth with expectations to attend college were surveyed during their senior year of high school, one year later, and four years later. Participants who did not achieve their short-term expectations had lower educational attainment four years later but were not less satisfied with their educational progress. The negative consequences of falling short of one's expectations were restricted to individuals with less ambitious short-term expectations. Thus, the benefits of ambitious short-term expectations for youth may outweigh the costs.

  19. Extrinsic Versus Intrinsic Benefits: Challenging Categories Used to Define the Value of Music in Schools

    Directory of Open Access Journals (Sweden)

    Alexander Hew Dale Crooke

    2016-07-01

    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.

    A recent roof renovation at the University of Texas Health Science Center in Houston (UTHSC) was based on the principles of sustainable development in order to create a place of health and well-being and to pursue integrated design solutions. The project addressed issues associated with the urban heat island condition, and problematic air quality in Houston. The first roofing option that was considered was Cool Roofing that would use either a white reflective surfacing or a garden roof. One of the buildings planned for roof replacement was the School of Public Health, a 10-storey structure composed of structural concrete framing. The existing roof system consisted of a spray-applied polyurethane foam roof covering applied over a gravel surfaced built-up roof membrane that was installed over a thermosetting asphaltic fill installed over a structural concrete deck. It was determined that this roof would be a good potential candidate for the installation of an extensive garden roof system. Four different mock-up samples of various extensive garden roof assemblies were constructed to test representative material types and assemblies. The subject area was divided into the following 4 quadrants in which the following systems were installed: (1) American Hydrotech system with Monolithic Membrane 6125-FR consisting of a hot-applied rubberized liquid asphalt reinforced with a polyester fabric, (2) Sarnafil G 476 system consisting of a prefabricated, fiberglass reinforced PVC thermoplastic single-ply membrane that is 80 mils thick, (3) Grace system with Procor Deck System 3R consisting of a cold-vulcanized, fluid-applied synthetic rubber membrane with a polyester reinforcing fabric, and (4) Siplast with Teranap System consisting of a two-ply SBS modified bitumen membrane composed of a smooth-surfaced modified bitumen fiberglass-reinforced base. After the installation of the growing medium, UTHSC personnel planted a variety of vegetation species and seeds in the quadrants

    The interconnected systems provide large technical and economic benefits which, evaluated and contrasted with the associated network investment cost, usually produce important net savings. There are continental electrical systems formed by many interconnected subsystems. The optimal size of an interconnection should be defined within an economic background. It is necessary to take into account the global environmental effects. The approach and results of studies carried out by Red Electrica is presented, in order to analyse both economic and environmental benefits resulting from an increase in the present Spanish interconnection capacities. From both economic and environmental points of view, the development of the interconnected systems is highly positive. (author). 4 refs.

    Using data from the National Longitudinal Transition Study-2 (NLTS2), this study examines the career and technical education (CTE) course taking of high school students with learning disabilities (LD) in the context of the national movement toward higher standards for determining whether students leave high school "college and career ready." Descriptive analyses document the extent of general education CTE course taking overall by students with LD and their engagement in a concentrated program of occupationally specific general education CTE, a level of course taking early research has linked to improved post-high school employment outcomes. Propensity score modeling was used to determine whether either type of CTE course taking is related to higher odds of full-time employment after high school and whether results differ with the length of time youth were out of high school. Results show no benefits of CTE course taking overall, but demonstrate a significant positive effect for participating in a concentration of occupationally specific CTE in the first 2 post-high school years; effects are nonsignificant for later years. The implications for high school programming and transition planning for students with LD are discussed.

  3. Do recommender systems benefit users? a modeling approach

    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.

    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.

    Full Text Available One of the methods used in the design and utilization of distribution systems to improve power quality and reliability of load power supply of consumers, is the application of distributed generation (DG sources. In this paper, a new method is proposed for the design and utilization of distribution networks with DG resources application by finding the optimal sitting and sizing of generated power of DG with the aim of maximization of its benefits to costs. The benefits for DG are considered as system losses reduction, system reliability improvement and benefits from the sale electricity or from lack of purchase of electricity from the main system. The costs of DG are considered as initial capital, maintenance and operation cost and investment cost. In this paper to solve the optimal sitting and sizing problem a Modified particle swarm optimization (PSO is applied. Simulations are presented on a 69-bus test distribution system to verify the effectiveness of the proposed method. Results showed that the proposed high-power method to find the optimal points of problem is faster and application of DG resources reduced the losses, costs and improved the system voltage profile.

    Contemporary forces, including the growing nursing shortage, the aging population, and the emphasis on patient safety, are increasing the pressure on healthcare facilities to use information systems to achieve better outcomes. Use of information systems improves nurses' ability to make decisions in a timely manner; however, nurses are still reluctant about or avoiding using information systems in their daily work. The purpose of this study was to explore the relationships among age, nursing education, computer experience, user involvement in implementation, nursing management support to use information systems, nurses' information system use, and information system outcomes (benefits and satisfaction). The study used an input-process-outcome framework, a descriptive correlational design, and a mailed survey with a random sample of staff nurses. Computer experience, user involvement, and nursing management support were found to significantly explain information system use. In addition, information system use was found to significantly explain nurses' perception of the benefits of using information systems and their satisfaction with using information systems. These results assist nursing administrators and leaders to change and/or restructure the appropriate work environment to enhance nurses' information system use and increase their satisfaction, thereby improving patient outcomes.

  16. Mixed grazing systems benefit both upland biodiversity and livestock production.

    Directory of Open Access Journals (Sweden)

    Mariecia D Fraser

    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

    Sewage treatment, treated water treatment and sludge treatment are three basic units of an integrated sewage treatment system. This work assessed the influence of reusing or discharge of treated water and sludge landfill or compost on the sustainability of an integrated sewage treatment system using emergy analysis and newly proposed emergy indicators. This system's value included its environmental benefits and the products. Environmental benefits were the differences of the environmental service values before and after sewage treatment. Due to unavailability of data of the exchanged substance and energy in the internal system, products' values were attained by newly proposed substitution values. The results showed that the combination of sewage treatment, treated water reuse and sludge landfill had the strongest competitiveness, while the combination of sewage treatment, treated water reuse and earthworm compost was the most sustainable. Moreover, treated water reuse and earthworm compost were helpful for improving the sustainability of the integrated sewage treatment system. The quality of treated water and local conditions should be also considered when implementing the treated water reuse or discharge. The resources efficiency of earthworm compost unit needed to be further improved. Improved emergy indices were more suitable for integrated sewage treatment systems.

    Age related muscle loss, known as sarcopenia, is a major factor in disability, loss of mobility and quality of life in the elderly. There are many proposed mechanisms of age-related muscle loss that include the endocrine system. A variety of hormones regulate growth, development and metabolism throughout the lifespan. Hormone activity may change with age as a result of reduced hormone secretion or decreased tissue responsiveness. This review will focus on the complex interplay between the endocrine system, aging and skeletal muscle and will present possible benefits of therapeutic interventions for sarcopenia.

  19. Communicating the Benefits of a Full Sequence of High School Science Courses

    Science.gov (United States)

    Nicholas, Catherine Marie

    High school students are generally uninformed about the benefits of enrolling in a full sequence of science courses, therefore only about a third of our nation's high school graduates have completed the science sequence of Biology, Chemistry and Physics. The lack of students completing a full sequence of science courses contributes to the deficit in the STEM degree production rate needed to fill the demand of the current job market and remain competitive as a nation. The purpose of the study was to make a difference in the number of students who have access to information about the benefits of completing a full sequence of science courses. This dissertation study employed qualitative research methodology to gain a broad perspective of staff through a questionnaire and document review and then a deeper understanding through semi-structured interview protocol. The data revealed that a universal sequence of science courses in the high school district did not exist. It also showed that not all students had access to all science courses; students were sorted and tracked according to prerequisites that did not necessarily match the skill set needed for the courses. In addition, the study showed a desire for more support and direction from the district office. It was also apparent that there was a disconnect that existed between who staff members believed should enroll in a full sequence of science courses and who actually enrolled. Finally, communication about science was shown to occur mainly through counseling and peers. A common science sequence, detracking of science courses, increased communication about the postsecondary and academic benefits of a science education, increased district direction and realistic mathematics alignment were all discussed as solutions to the problem.

    As a laboratory certified to ISO 9001:2000 and accredited to ISO 17025, rtech laboratories has incorporated an overall system for technical and quality management, which results in benefits observed in daily laboratory practices. Technical requirements were updated to include the addition of formal personnel training plans and detailed records, method development and validation procedures, measurement of method uncertainty, and a defined equipment calibration and maintenance program. In addition, a stronger definition of the sample preparation process was documented to maintain consistency in sampling, and a more rigorous quality control monitoring program was implemented for chemistry and microbiology. Management quality improvements focused on document control to maintain consistent analytical processes, improved monitoring of supplier performance, a contract review process for documenting customer requirements, and a system for handling customer comments and complaints, with continuous improvement through corrective and preventive action procedures and audits. Quarterly management review of corrective actions, nonconforming testing, and proficiency testing aid in determining long-term trending. The practical benefits of these technical and management quality improvements are seen on a daily basis in the laboratory. Faster identification and resolution of issues regarding methods, personnel or equipment, improved customer satisfaction, meeting quality requirements of specialized customers, and overall increased laboratory business are all the result of implementing an effective quality system.

    2011-12-01

    This review evaluates the current understanding of the benefits and risks of physical activity and exercise on the gastrointestinal system. A significant portion of endurance athletes are affected by gastrointestinal symptoms, but most symptoms are transient and do not have long-term consequences. Conversely, physical activity may have a protective effect on the gastrointestinal system. There is convincing evidence that physical activity reduces the risk of colon cancer. The evidence is less convincing for gastric and pancreatic cancers, gastroesophageal reflux disease, peptic ulcer disease, nonalcoholic fatty liver disease, cholelithiasis, diverticular disease, irritable bowel syndrome, and constipation. Physical activity may reduce the risk of gastrointestinal bleeding and inflammatory bowel disease, although this has not been proven unequivocally. This article provides a critical review of the evidence-based literature concerning exercise and physical activity effects on the gastrointestinal system and provides physicians with a better understanding of the evidence behind exercise prescriptions for patients with gastrointestinal disorders. Well-designed prospective randomized trials evaluating the risks and benefits of exercise and physical activity on gastrointestinal disorders are recommended for future research.

    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.

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.

  1. NON-TRADITIONAL SPORTS AT SCHOOL. BENEFITS FOR PHYSICAL AND MOTOR DEVELOPMENT

    Directory of Open Access Journals (Sweden)

    2010-12-01

    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

    Physical education (PE) programs are evolving from a traditional skill-centered model to a health-centered model that focuses on time engaged in moderate to vigorous physical activity (MVPA). However, improvements in muscular fitness and fundamental movement skills are prerequisites for continuous participation in MVPA. The purpose of this study was to examine the effects of integrative strength and skill-based training on measures of physical fitness in children during primary school PE. Children from two fourth grade PE classes were cluster randomized into either a fundamental integrative training (FIT) group (n = 20) or a control (CON) group (n = 21). The 8-week FIT program was performed twice per week during the first ∼ 1 5 minutes of each PE class and consisted of a circuit of strength and skill-based exercises. All participants were assessed for health- and skill-related fitness before and after the intervention. The outcome variables were analyzed via 2 × 2 repeated measures analysis of variance with post hoc analysis. A significant (p ≤ 0.05) interaction of group by time was observed in FIT participants with improvements in aerobic capacity, push-ups, sit and reach flexibility, and single-leg hop. There were no groups by time effects for the sit-up and long jump tests. No injuries were reported. These findings highlight the potential benefits of integrating both health- and skill-related fitness components into primary school PE as evidenced by improvements in measures of aerobic capacity and muscular fitness in children.

  3. The Benefits of Fine Art Integration into Mathematics in Primary School

    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.

  4. Toward an evaluation of an integrated clinical imaging system: identifying clinical benefits.

    1996-09-01

    Integrated clinical imaging systems can provide the foundation for future computer-based patient record systems as recommended by the Institute of Medicine. However, documenting the benefits of such systems is difficult. This paper reports an evaluation of a clinical imaging system that is integrated with an on-line electronic patient record. The evaluation used interviews and observations to identify what physicians thought were the benefits of this system. Reported benefits may be classified into patient care benefits, educational benefits, and productivity and cost-reduction benefits Physicians said that the imaging system provided patient care benefits by: improving clinical communication and decision making, making care more patient-based, reducing the number of procedures and patient risks, and improving record keeping. Educational benefits they reported included: improving communication, providing broad "real" experience, and improving supervision. These benefits may be reflected in increased productivity and cost reduction by increasing time savings, reducing clerical work, improving morale, and reducing the costs of care. The approach described in this study was valuable in identifying potential benefits of a clinical information system. The findings point the way to realization of benefits for other systems, and, ultimately, for computer-based patient records.

  9. The Benefits of Cooperative Learning to Socio-scientific Discussion in Secondary School Science

    Day, Stephen P.; Bryce, Tom G. K.

    2013-06-01

    The aim of this research was to determine the benefits of cooperative learning to opening up socio-scientific discussion in secondary science. Seventy-four classes of 20 13-14-year-old pupils in one secondary school were observed engaging in discussion concerning climate change over three rounds of action research involving 12 teachers associated with the implementation of a Topical Science strand of a new national science curriculum. Pupil views on the cooperative learning approach used to facilitate the lessons and the associated discussion were determined using a pupil questionnaire (n = 171). By the end of the action research, the overall average typical exchange in the observed lessons was between pupil-to-pupil (mean ± SD, 41% ± 5%) and pupil-to-teacher (32% ± 4%) with teacher-to-pupil interactions accounting for only 27% ± 5% of exchanges. However, the pace of the typical exchanges was predominantly fast with most of the questions being a mixture of low order on task questions from teacher-to-pupil; technical exchanges, inquiring what to do from pupil-to-teacher; and quiz questions from teacher-to-pupil or from pupil-to-pupil. Questionnaire data indicated that overall 50.3% of pupils enjoyed the discussion (on global warming) and 59.7% did not find it boring. Nevertheless, only 45% felt that they were given the chance to express their own opinions during these discussions. Prior to these lessons, 59.6% were not interested in the issue of climate change and global warming. Cooperative learning facilitated a shift in the pattern of typical exchanges away from a teacher-dominated discourse towards a more pupil-centred, open discourse.

  16. Meanings and robustness: Propositions for enhancing benefit sharing in social-ecological systems

    Directory of Open Access Journals (Sweden)

    Ernita van Wyk

    2014-08-01

    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.

    Full Text Available Standing desks have proven to be effective and viable solutions to combat sedentary behavior among children during the school day in studies around the world. However, little is known regarding the potential of such interventions on cognitive outcomes in children over time. The purpose of this pilot study was to determine the neurocognitive benefits, i.e., improvements in executive functioning and working memory, of stand-biased desks and explore any associated changes in frontal brain function. 34 freshman high school students were recruited for neurocognitive testing at two time points during the school year: (1 in the fall semester and (2 in the spring semester (after 27.57 (1.63 weeks of continued exposure. Executive function and working memory was evaluated using a computerized neurocognitive test battery, and brain activation patterns of the prefrontal cortex were obtained using functional near infrared spectroscopy. Continued utilization of the stand-biased desks was associated with significant improvements in executive function and working memory capabilities. Changes in corresponding brain activation patterns were also observed. These findings provide the first preliminary evidence on the neurocognitive benefits of standing desks, which to date have focused largely on energy expenditure. Findings obtained here can drive future research with larger samples and multiple schools, with comparison groups that may in turn implicate the importance of stand-biased desks, as simple environmental changes in classrooms, on enhancing children’s cognitive functioning that drive their cognitive development and impact educational outcomes.

    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.

    2013-10-01

    The hearing is routinely tested in all newborns in most European countries. Thereafter, no hearing test is performed in a systematic way, despite the many conditions that can cause hearing loss in the first years of life. If language acquisition is possible with only one ear, even a unilateral hearing loss can be the cause of learning difficulties at school. In Geneva, a screening program for hearing deficit was introduced in 1955 in all primary schools of the canton. This paper shows the efficiency of the program, which can detect unnoticed deafness, sometimes in children whose neonatal screening had proved normal. Such a program should be applied to all private schools and to schools for disabled children.

    2008-01-01

    In the technology-rich environment of healthcare, hospital documentation systems need to be developed so that quality benefits are realized and are more evident. The effects of nurses' perceptions of ease of use, usefulness, and documentation accuracy on their perceptions of improved quality benefits from information systems were studied based on a proposed model. This model was developed from variables in both technology acceptance and healthcare literature. Usefulness and documentation accuracy of an information system were found to be highly influential in the nurses' perception of quality benefits from the system. System designers need to be keenly aware of nurses' need for useful and accurate systems so that quality benefits can be discovered. Further research is needed to more thoroughly explore the impact of technology on quality of care in nursing.

  13. Targeting bacterial secretion systems: benefits of disarmament in the microcosm.

    2007-03-01

    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.

    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.

  3. Urban governance and the systems approaches to health-environment co-benefits in cities.

    Oliveira, Jose A Puppim de; Doll, Christopher N H; Siri, José; Dreyfus, Magali; Farzaneh, Hooman; Capon, Anthony

    2015-11-01

    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.

  8. The Benefit System and its scope in contemporary orthodontic protocols

    Directory of Open Access Journals (Sweden)

    Benedict Wilmes

    2015-01-01

    Full Text Available Currently, the alveolar process is the most preferred insertion site for orthodontic mini-implants. However, due to the varying bone quality and the risk of root contact, the survival rate of implants inserted in the alveolar ridge still needs improvement. Other regions, such as the anterior palate and the mental region provide much better conditions for temporary anchorage device (TAD insertion since the amount and quality of the available bone are far superior. Mini-implants with different types of abutments and connectors allow the construction of versatile and cost efficient appliances for a large variety of orthopedic and orthodontic applications. Utilizing TAD′s in the anterior palate and the mental region eliminates the risk of root injury and takes the implants out of the path of tooth movement. The design of the interchangeable abutment system provides the orthodontist with a skeletal anchorage system that integrates easily into clinical practice and allows treatment of cases that were difficult or impossible to treat previously.

    Science.gov (United States)

    Lawing, Pierce L.; Dress, David A.; Kilgore, Robert A.

    1987-01-01

    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.

    Science.gov (United States)

    Manning, C. B.

    2013-12-01

    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

    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

    Over the last two decades, NASA has conducted several experiments in integrated flight-propulsion control. Benefits have included improved maneuverability; increased thrust, range, and survivability; reduced fuel consumption; and reduced maintenance. This paper presents the basic concepts for control integration, examples of implementation, and benefits. The F-111E experiment integrated the engine and inlet control systems. The YF-12C incorporated an integral control system involving the inlet, autopilot, autothrottle, airdata, navigation, and stability augmentation systems. The F-15 research involved integration of the engine, flight, and inlet control systems. Further extension of the integration included real-time, onboard optimization of engine, inlet, and flight control variables; a self-repairing flight control system; and an engines-only control concept for emergency control. The F-18A aircraft incorporated thrust vectoring integrated with the flight control system to provide enhanced maneuvering at high angles of attack. The flight research programs and the resulting benefits of each program are described.

    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

    In the long ethical history in ancient China, there were always debates on righteousness and benefit. The best-known ethical schools were Confucianism, which values righteousness but despises benefit, and Legalism, which values benefit but de- spises righteousness. Besides the two schools, there were some schools which advocated the integration of righteousness and benefit. they were Mohism combining righteousness with benefit, the school represented by Sima Qian in the West Han Dynasty and Wang Chong and Huan Tan in the East Han Dynasty who argued that righteousness comes from benefit, and the school led by Li Gou, Chen Liang, Ye Shi, Wang Anshi in the Song Dynasty and Yan Yuan in the early Qing Dynasty who exclaimed to balance righteousness and benefit. By analyzing and comparing these schools, we can further confirm their ideas on righteousness and benefit, and their similarities and differences.%中国古代伦理史上的义利之辨历时长久,在为人熟知的重义轻利的儒家和重利轻义的法家之外,有主张义利统一的流派:墨家的义利相合论;西汉司马迁、东汉王充和桓潭等人的义以利生论;宋代李觏、陈亮、叶适、王安石、清初颜元等人的义利并重论。梳理把握传统伦理思想中的义利统一流派的基本构成,可以对其理论价值及其异同进一步加以确认。

    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.

    2015-12-01

    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.

    2013-01-01

    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.

  13. System-agnostic clinical decision support services: benefits and challenges for scalable decision support.

    Kawamoto, Kensaku; Del Fiol, Guilherme; Orton, Charles; Lobach, David F

    2010-01-01

    System-agnostic clinical decision support (CDS) services provide patient evaluation capabilities that are independent of specific CDS systems and system implementation contexts. While such system-agnostic CDS services hold great potential for facilitating the widespread implementation of CDS systems, little has been described regarding the benefits and challenges of their use. In this manuscript, the authors address this need by describing potential benefits and challenges of using a system-agnostic CDS service. This analysis is based on the authors' formal assessments of, and practical experiences with, various approaches to developing, implementing, and maintaining CDS capabilities. In particular, the analysis draws on the authors' experience developing and leveraging a system-agnostic CDS Web service known as SEBASTIAN. A primary potential benefit of using a system-agnostic CDS service is the relative ease and flexibility with which the service can be leveraged to implement CDS capabilities across applications and care settings. Other important potential benefits include facilitation of centralized knowledge management and knowledge sharing; the potential to support multiple underlying knowledge representations and knowledge resources through a common service interface; improved simplicity and componentization; easier testing and validation; and the enabling of distributed CDS system development. Conversely, important potential challenges include the increased effort required to develop knowledge resources capable of being used in many contexts and the critical need to standardize the service interface. Despite these challenges, our experiences to date indicate that the benefits of using a system-agnostic CDS service generally outweigh the challenges of using this approach to implementing and maintaining CDS systems.

    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.

    2008-01-01

    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.

    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

    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).

  19. Does migration benefit the schooling of children left behind?: Evidence from rural northwest China

    2013-07-01

    Full Text Available BACKGROUND While many studies have found that migration can benefit home communities and family members left behind by increasing household income, thus easing liquidity constraints on investment; less is known about how "internal" migration and remittances affect the educational performance of the children who are left behind in the source communities. OBJECTIVE My aim in this paper is to examine the effects of migration on the educational attainment of left-behind rural children in northwest China. To gain a better understanding of whether the educational performance of these children improves or suffers when adult family members migrate, I attempt to disentangle the effects of remittances from the effects of migration. METHODS The data used in this study come from the 2004 wave of the Gansu Survey of Children and Families. To account for the possible endogeneity of migration-related variables, I use the migration network variables to instrument for different migration strategies. RESULTS The results show that the absence of adult household members, including parents, has a negative effect on the educational performance of the children left behind, but that remittances can partially compensate for this loss. Boys' educational performance does not seem to be greatly affected by the migration of adult household members. By contrast, the absence of adult household members is shown to have a large negative effect on girls' educational performance, and the positive effect of remittances is also found to be significant for girls. CONCLUSIONS The findings may be of interest to other developing countries with large internal migration flows and to the relevant policy makers, as the results suggest that remittances sent home by out-migrants may serve as a channel for investing in human capital in the migrants' regions of origin, and especially for investing in the human capital of girls.

    Full Text Available In the background of decreasing fossil fuels and increasing environmental pollution, the wind-photovoltaic energy storage and transmission hybrid power system (or called the wind-PV-ES and transmission hybrid system has become a strategic choice to achieve energy sustainability. However, the comprehensive benefit evaluation of such a combined power system is in a relatively blank state in China, which will hinder the reasonable and orderly development of this station. Four parts, the technical performance, economic benefit, ecological impact and social benefit, are considered in this paper, and a multi-angle evaluation index system of the wind-PV-ES and transmission system is designed. The projection pursuit model is used to evaluated system functionality conventionally; relative entropy theory is used to evaluate the system functionality simultaneously; and a comprehensive benefit evaluation model of the technique for order preference by similar to ideal solution (TOPSIS considering both system functionality and proportionality is constructed. Finally, the national demonstration station of the wind-PV-ES-transmission system is taken as an example to testify to the practicability and validity of the evaluation index system and model.

    2011-06-01

    Full Text Available This study, based in the substantive area of school counselors, was conducted using classical grounded theory, an inductive, systemic method of data collection and analysis. The core variable, or the school counselors’ main concern and how they were resolving it, emerged as the need to develop and implement a comprehensive program within the complex ecology of a school. Working the system: Aligning to advantage was discovered to be the school counselors’ resolving process. The data revealed that as school counselors work the system, they engage in strategic actions of aligning to advantage themselves, others, and/or the overall system. Working the system comprises three stages: accessing, engaging, and sustaining, each associated with aligning behaviors, which have personal, interpersonal, and structural dimensions. The theory is useful to school counselors and other leaders engaged in systemic change in complex ecological systems.

    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.

    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.

    2003-09-02

    Energy Information Systems (EIS), which can monitor and analyze building energy consumption and related data throughout the Internet, have been increasing in use over the last decade. Though EIS developers describe the capabilities, costs, and benefits of EIS, many of these descriptions are idealized and often insufficient for potential users to evaluate cost, benefit and operational usefulness. LBNL has conducted a series of case studies of existing EIS and related technology installations. This study explored the following questions: (1) How is the EIS used in day-to-day operation? (2) What are the costs and benefits of an EIS? (3) Where do the energy savings come from? This paper reviews the process of these technologies from installation through energy management practice. The study is based on interviews with operators and energy managers who use EIS. Analysis of energy data trended by EIS and utility bills was also conducted to measure the benefit. This paper explores common uses and findings to identify energy savings attributable to EIS, and discusses non-energy benefits as well. This paper also addresses technologies related to EIS that have been demonstrated and evaluated by LBNL.

    Full Text Available Objective: To examine the prevalence and determinants of basic and/or attendance benefits among children involved with the child welfare system (CWS.Design: A register study of all children involved with CWS in Norway from 1997-2006.Participants: 96,354 children from the CWS group and 149,030 children who had never been in the CWS as a comparison group.Results: 11% of children involved with CWS received basic and/or attendance benefits compared to 3% in the comparison group. In multivariate logistic regression, the boys’ chances of ever receiving basic and/or attendance benefits were greater than the girls’ chances. The chances of receiving benefits increased nearly four to sixfold as a child becomes older. However, they decrease as the age at debut to CWS increases. It was also revealed that those children who stayed under child welfare for two or more years had an increased chance of ever receiving basic and/or attendance benefits. For children with reported behavioral disorders, the chances of basic and/or attendance benefits were nearly twofold. For children under home-based support and medication interventions, the chances of receiving basic and/or attendance benefits were greater than for children who were not under these interventions.Conclusion: Chronic health conditions that claim basic and/or attendance benefits were more prevalent among children involved with CWS than the general children’s population. This phenomenon may be explained by gender, age, age at debut to CWS, length of stay under CWS, types and reasons for interventions

    2011-10-01

    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.

    Medical education in the United States and Canada continues to evolve. However, many of the changes in pedagogy are being made without appropriate evaluation. Here, we attempt to evaluate the effectiveness of lecture capture technology as a learning tool in Podiatric medical education. In this pilot project, student performance in an inaugural lecture capture-supported biochemistry course was compared to that in the previous academic year. To examine the impact of online lecture podcasts on student performance a within-subjects design was implemented, a two way ANCOVA with repeated measures. The use of lecture capture-supported pedagogy resulted in significantly higher student test scores, than achieved historically using traditional pedagogy. The overall course performance using this lecture capture-supported pedagogy was almost 6% higher than in the previous year. Non-native English language speakers benefitted more significantly from the lecture capture-supported pedagogy than native English language speakers, since their performance improved by 10.0 points. Given that underrepresented minority (URM) students, whose native language is not English, makes up a growing proportion of medical school matriculates, these observations support the use of lecture capture technology in other courses. Furthermore, this technology may also be used as part of an academic enrichment plan to improve performance on the American Podiatric Medical Licensing Examination, reduce the attrition of URM students and potentially address the predicted minority physician shortage in 2020.

    Systems modeling represents an innovative approach for addressing the obesity epidemic at the community level. We developed an agent-based model of the Baltimore City food environment that permits us to assess the relative impact of different programs and policies, alone and in combination, and potential unexpected consequences. Based on this experience, and a review of literature, we have identified a set of principles, potential benefits, and challenges. Some of the key principles include the importance of early and multilevel engagement with the community prior to initiating model development and continued engagement and testing with community stakeholders. Important benefits include improving community stakeholder understanding of the system, testing of interventions before implementation, and identification of unexpected consequences. Challenges in these models include deciding on the most important, yet parsimonious factors to consider, how to model food source and food selection behavior in a realistic yet transferable manner, and identifying the appropriate outcomes and limitations of the model.

  1. How Decision Support Systems Can Benefit from a Theory of Change Approach.

    Science.gov (United States)

    Allen, Will; Cruz, Jennyffer; Warburton, Bruce

    2017-03-09

    Decision support systems are now mostly computer and internet-based information systems designed to support land managers with complex decision-making. However, there is concern that many environmental and agricultural decision support systems remain underutilized and ineffective. Recent efforts to improve decision support systems use have focused on enhancing stakeholder participation in their development, but a mismatch between stakeholders' expectations and the reality of decision support systems outputs continues to limit uptake. Additional challenges remain in problem-framing and evaluation. We propose using an outcomes-based approach called theory of change in conjunction with decision support systems development to support both wider problem-framing and outcomes-based monitoring and evaluation. The theory of change helps framing by placing the decision support systems within a wider context. It highlights how decision support systems use can "contribute" to long-term outcomes, and helps align decision support systems outputs with these larger goals. We illustrate the benefits of linking decision support systems development and application with a theory of change approach using an example of pest rabbit management in Australia. We develop a theory of change that outlines the activities required to achieve the outcomes desired from an effective rabbit management program, and two decision support systems that contribute to specific aspects of decision making in this wider problem context. Using a theory of change in this way should increase acceptance of the role of decision support systems by end-users, clarify their limitations and, importantly, increase effectiveness of rabbit management. The use of a theory of change should benefit those seeking to improve decision support systems design, use and, evaluation.

  3. Optimal Sizing of a Solar-Plus-Storage System for Utility Bill Savings and Resiliency Benefits

    Energy Technology Data Exchange (ETDEWEB)

    2016-12-12

    Solar-plus-storage systems can achieve significant utility savings in behind-the-meter deployments in buildings, campuses, or industrial sites. Common applications include demand charge reduction, energy arbitrage, time-shifting of excess photovoltaic (PV) production, and selling ancillary services to the utility grid. These systems can also offer some energy resiliency during grid outages. It is often difficult to quantify the amount of resiliency that these systems can provide, however, and this benefit is often undervalued or omitted during the design process. We propose a method for estimating the resiliency that a solar-plus-storage system can provide at a given location. We then present an optimization model that can optimally size the system components to minimize the lifecycle cost of electricity to the site, including the costs incurred during grid outages. The results show that including the value of resiliency during the feasibility stage can result in larger systems and increased resiliency.

    1999-01-01

    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

    Fisk, William J.; Seppanen, Olli; Faulkner, David; Huang, Joe

    2004-02-01

    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.

    Gould, A. D.; Sneider, C.; Farmer, E.; Erickson, J.

    2015-12-01

    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/

  16. Implementation and optimization of smart infusion systems: are we reaping the safety benefits?

    Science.gov (United States)

    Trbovich, Patricia L; Cafazzo, Joseph A; Easty, Anthony C

    2013-01-01

    To address the high incidence of infusion errors, manufacturers have replaced the development of standard infusion pumps with smart pump systems. The implementation and ongoing optimization processes for smart pumps are more complex, as they require larger coordinated efforts with stakeholders throughout the medication process. If improper implementation/optimization processes are followed, hospitals invest in this technology while extracting minimal benefit. We assessed the processes hospitals employed when migrating from standard to smart infusion systems, and the extent to which they leveraged their investments from both a systems and resource perspective. Twenty-nine hospitals in Ontario, Canada, were surveyed that had either implemented smart pump systems or were in the process of implementing, representing a response rate of 69%. Results demonstrated that hospitals purchased smart pumps for reasons other than safety, did not involve a multidisciplinary team during implementation, made little effort to standardize drug concentrations or develop drug libraries and dosing limits, seldom monitored how nurses use the pumps, and failed to ensure wireless connectivity to upgrade protocols and download use data. Consequently, they are failing to realize the safety benefits these systems can provide.

    1998-01-01

    Economic aspects are decisive for industrial acceptance of research concepts including the promising ideas in fault tolerant control. Fault tolerance is the ability of a system to detect, isolate and accommodate a fault, such that simple faults in a sub-system do not develop into failures...... at a system level. In a design phase for an industrial system, possibilities span from fail safe design where any single point failure is accommodated by hardware, over fault-tolerant design where selected faults are handled without extra hardware, to fault-ignorant design where no extra precaution is taken....... The objective of this paper is to help, in the early product development state, to find the economical most suitable scheme. A salient result is that with increased customer awareness of total cost of ownership, new products can benefit significantly from applying fault tolerant control principles....

    2014-06-01

    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.

  1. The United States Department of Energy Office of Industrial Technology`s Technology Benefits Recording System

    Energy Technology Data Exchange (ETDEWEB)

    Hughes, K.R.; Moore, N.L.

    1994-09-01

    The U.S. Department of Energy (DOE) Office of Industrial Technology`s (OIT`s) Technology Benefits Recording System (TBRS) was developed by Pacific Northwest Laboratory (PNL). The TBRS is used to organize and maintain records of the benefits accrued from the use of technologies developed with the assistance of OIT. OIT has had a sustained emphasis on technology deployment. While individual program managers have specific technology deployment goals for each of their ongoing programs, the Office has also established a separate Technology Deployment Division whose mission is to assist program managers and research and development partners commercialize technologies. As part of this effort, the Technology Deployment Division developed an energy-tracking task which has been performed by PNL since 1977. The goal of the energy-tracking task is to accurately assess the energy savings impact of OIT-developed technologies. In previous years, information on OIT-sponsored technologies existed in a variety of forms--first as a hardcopy, then electronically in several spreadsheet formats that existed in multiple software programs. The TBRS was created in 1993 for OIT and was based on information collected in all previous years from numerous industrial contacts, vendors, and plants that have installed OIT-sponsored technologies. The TBRS contains information on technologies commercialized between 1977 and the present, as well as information on emerging technologies in the late development/early commercialization stage of the technology life cycle. For each technology, details on the number of units sold and the energy saved are available on a year-by-year basis. Information regarding environmental benefits, productivity and competitiveness benefits, or impact that the technology may have had on employment is also available.

    1998-07-01

    Although major accidents involving school buses are rare (only about 0.3% of all fatal crashes since 1986 are classified as school-bus-related), even minor accidents and breakdowns cause a great deal of parental anxiety. The objective of this research is to design an efficient, cost-effective, accurate, and secure system that will track individual school buses and communicate appropriate information to the school system`s central administration unit, to the school transportation administrator, and to parents of children on the bus. The greatest benefit of the proposed information system is that parents and officials can always know the location and condition (these conditions would vary depending on the needs of a particular school system) of the school buses. In case of an accident or mechanical problem, when emergency crews are needed, they can be dispatched almost immediately with a good understanding of the problem and the exact location of the bus. In addition to being able to track the bus while the child is on board, parents will be able to determine the location of their child`s bus prior to its arrival in the morning in order to prevent the child from needing to wait outside in inclement weather. The information available to parents can also be expanded to include maps of limited routes (e.g., snow routes). Basically, the Bus 54 concept consists of a bus component and a central data processing unit. Each bus will be outfitted with a global positioning satellite (GPS) device, a wireless communication device, and wireless data communication service. The central data processing unit will receive and process information from the buses and provide information access to parents and officials via an Internet link.

  5. Cost-Benefit Analysis of Confidentiality Policies for Advanced Knowledge Management Systems

    Energy Technology Data Exchange (ETDEWEB)

    May, D

    2003-03-01

    Knowledge Discovery (KD) processes can create new information within a Knowledge Management (KM) system. In many domains, including government, this new information must be secured against unauthorized disclosure. Applying an appropriate confidentiality policy achieves this. However, it is not evident which confidentiality policy to apply, especially when the goals of sharing and disseminating knowledge have to be balanced with the requirements to secure knowledge. This work proposes to solve this problem by developing a cost-benefit analysis technique for examining the tradeoffs between securing and sharing discovered knowledge.

    2016-07-01

    Full Text Available The Spanish education system has become one of the worst, as evaluated by the PISA-OCDE assessments. The tip of the iceberg of this education systemwhich constantly proves to have truly poor results- is showing itself in the children’s homes, by the assignment of homework. Despite the fact that an increasing number of studies show evidence that assigning homework to primary school children (especially the youngest ones is useless, Spanish primary school students are overwhelmed with their school duties. Likewise, the World Health Organisation has reported that secondary school students feel they are living under high pressure due to their school responsibilities. It is imperative to enforce a change in the Spanish education system, with a clear aim of reducing homework load and students’ stress levels. Promoting the right change will provide the Spanish education system with better results and achieve students’ proper wellbeing.

    1995-06-01

    This report evaluates telerobotic and teleoperational arm-based retrieval systems that require advanced robotic controls. These systems will be deployed in waste retrieval activities in Hanford`s Single Shell Tanks (SSTs). The report assumes that arm-based, retrieval systems will combine a teleoperational arm and control system enhanced by a number of advanced and telerobotic controls. The report describes many possible enhancements, spanning the full range of the control spectrum with the potential for technical maturation. The enhancements considered present a variety of choices and factors including: the enhancements to be included in the actual control system, safety, detailed task analyses, human factors, cost-benefit ratios, and availability and maturity of technology. Because the actual system will be designed by an offsite vendor, the procurement specifications must have the flexibility to allow bidders to propose a broad range of ideas, yet build in enough restrictions to filter out infeasible and undesirable approaches. At the same time they must allow selection of a technically promising proposal. Based on a preliminary analysis of the waste retrieval task, and considering factors such as operator limitations and the current state of robotics technology, the authors recommend a set of enhancements that will (1) allow the system to complete its waste retrieval mission, and (2) enable future upgrades in response to changing mission needs and technological advances.

    Science.gov (United States)

    Creech, Stephen D.; Patel, Keyur

    2013-01-01

    The National Aeronautics and Space Administration's (NASA's) proposed Europa Clipper mission would provide an unprecedented look at the icy Jovian moon, and investigate its environment to determine the possibility that it hosts life. Focused on exploring the water, chemistry, and energy conditions on the moon, the spacecraft would examine Europa's ocean, ice shell, composition and geology by performing 32 low-altitude flybys of Europa from Jupiter orbit over 2.3 years, allowing detailed investigations of globally distributed regions of Europa. In hopes of expediting the scientific program, mission planners at NASA's Jet Propulsion Laboratory are working with the Space Launch System (SLS) program, managed at Marshall Space Flight Center. Designed to be the most powerful launch vehicle ever flown, SLS is making progress toward delivering a new capability for exploration beyond Earth orbit. The SLS rocket will offer an initial low-Earth-orbit lift capability of 70 metric tons (t) beginning with a first launch in 2017 and will then evolve into a 130 t Block 2 version. While the primary focus of the development of the initial version of SLS is on enabling human exploration missions beyond low Earth orbit using the Orion Multi-Purpose Crew Vehicle, the rocket offers unique benefits to robotic planetary exploration missions, thanks to the high characteristic energy it provides. This paper will provide an overview of both the proposed Europa Clipper mission and the Space Launch System vehicle, and explore options provided to the Europa Clipper mission for a launch within a decade by a 70 t version of SLS with a commercially available 5-meter payload fairing, through comparison with a baseline of current Evolved Expendable Launch Vehicle (EELV) capabilities. Compared to that baseline, a mission to the Jovian system could reduce transit times to less than half, or increase mass to more than double, among other benefits. In addition to these primary benefits, the paper will

    Science.gov (United States)

    Carter, Timothy; Keeler, Andrew

    2008-05-01

    The built environment has been a significant cause of environmental degradation in the previously undeveloped landscape. As public and private interest in restoring the environmental integrity of urban areas continues to increase, new construction practices are being developed that explicitly value beneficial environmental characteristics. The use of vegetation on a rooftop--commonly called a green roof--as an alternative to traditional roofing materials is an increasingly utilized example of such practices. The vegetation and growing media perform a number of functions that improve environmental performance, including: absorption of rainfall, reduction of roof temperatures, improvement in ambient air quality, and provision of urban habitat. A better accounting of the green roof's total costs and benefits to society and to the private sector will aid in the design of policy instruments and educational materials that affect individual decisions about green roof construction. This study uses data collected from an experimental green roof plot to develop a benefit cost analysis (BCA) for the life cycle of extensive (thin layer) green roof systems in an urban watershed. The results from this analysis are compared with a traditional roofing scenario. The net present value (NPV) of this type of green roof currently ranges from 10% to 14% more expensive than its conventional counterpart. A reduction of 20% in green roof construction cost would make the social NPV of the practice less than traditional roof NPV. Considering the positive social benefits and relatively novel nature of the practice, incentives encouraging the use of this practice in highly urbanized watersheds are strongly recommended.

    Thipphavong, Jane; Swenson, Harry N.; Lin, Paul; Seo, Anthony Y.; Bagasol, Leonard N.

    2011-01-01

    NASA has developed a capability for terminal area precision scheduling and spacing (TAPSS) to increase the use of fuel-efficient arrival procedures during periods of traffic congestion at a high-density airport. Sustained use of fuel-efficient procedures throughout the entire arrival phase of flight reduces overall fuel burn, greenhouse gas emissions and noise pollution. The TAPSS system is a 4D trajectory-based strategic planning and control tool that computes schedules and sequences for arrivals to facilitate optimal profile descents. This paper focuses on quantifying the efficiency benefits associated with using the TAPSS system, measured by reduction of level segments during aircraft descent and flight distance and time savings. The TAPSS system was tested in a series of human-in-the-loop simulations and compared to current procedures. Compared to the current use of the TMA system, simulation results indicate a reduction of total level segment distance by 50% and flight distance and time savings by 7% in the arrival portion of flight (200 nm from the airport). The TAPSS system resulted in aircraft maintaining continuous descent operations longer and with more precision, both achieved under heavy traffic demand levels.

    Full Text Available The energy conservation achieved by utilizing waste heat in the energy and industrial sectors has became more and more important after the energy crisis in the 1970s because it plays a vital role in the potential energy-efficiency improvement. In this regard, cogeneration (combined heat and power, CHP systems are thus becoming attractive due to the energy, economic, and environmental policies for pursuing stable electricity supply, sustainable development and environmental pollution mitigation in Taiwan. The objective of this paper is to present an updated analysis of CHP systems in Taiwan during the period from 1990 to 2010. The description in the paper is thus based on an analysis of electricity supply/consumption and its sources from CHP systems during the past two decades, and centered on two important regulations in compliance with CHP systems (i.e., Energy Management Law and Environmental Impact Assessment Act. Based on the total net power generation from CHP systems (i.e., 35,626 GWh in 2011, it was found that the carbon dioxide reduction benefits were estimated to be around 20,000 Gg.

    Full Text Available Construction industry is considered among the most crucial sectors in developing countries where it is capable to drive a nation towards progressive development as it provides a positive platform to other industries. Implementation of Industrialized Building System (IBS has been acknowledged as an effective measure to increase capability within the industry as compared to the conventional methods. The purpose of this study is to present the benefits of implementing IBS from contractors’ viewpoint. Questionnaire forms were distributed to 683 construction firms registered under the Construction Industry Development Board of Malaysia operating in the states of Penang, Selangor, Kuala Lumpur and Johor. A total of 254 questionnaire forms were returned duly completed. The collected data was analysed using the Conformity Index. Three main benefits gained by implementing IBS from the contractors’ perspective are (1 IBS increases the productivity of construction works, (2 IBS reduces concrete mixing activities at construction sites and (3 IBS reduces the overall duration of construction work. These results indicate that the contractors are focusing more on completing construction works with the help of IBS implementation at construction sites. Also with IBS, it is able to minimize the problem of site mismanagement/disorganization through a significant reduction of in-situ wet concrete works.

  7. Net environmental benefit: introducing a new LCA approach on wastewater treatment systems.

    Science.gov (United States)

    Godin, D; Bouchard, C; Vanrolleghem, P A

    2012-01-01

    Life cycle assessment (LCA) allows evaluating the potential environmental impacts of a product or a service in relation to its function and over its life cycle. In past LCAs applied to wastewater treatment plants (WWTPs), the system function definition has received little attention despite its great importance. This has led to some limitations in LCA results interpretation. A new methodology to perform LCA on WWTPs is proposed to avoid those limitations. It is based on net environmental benefit (NEB) evaluation and requires assessing the potential impact of releasing wastewater without and with treatment besides assessing the impact of the WWTP's life cycle. The NEB allows showing the environmental trade-offs between avoided impact due to wastewater treatment and induced impact by the WWTP's life cycle. NEB is compared with a standard LCA through the case study of a small municipal WWTP consisting of facultative aerated lagoons. The NEB and standard LCA show similar results for impact categories solely related to the WWTP's life cycle but differ in categories where wastewater treatment environmental benefit is accounted for as NEB considers influent wastewater quality whereas standard LCA does not.

    Air pollution is a severe problem in major urban areas due to increasing numbers of vehicles, reduced road capacity and few investments in public transportation, especially in developing countries. Public transportation has a special role in avoiding congestion and consequent environmental and health impacts but is considered expensive. The objective of this paper was to analyze the benefits of the São Paulo subway in terms of the air pollution in the city through strikes events, analyzing both the health outcomes and the related economic burden. For the strike events, increases in air pollutant concentrations during the strike day was observed when compared to a similar day in terms of day of the week and meteorological conditions. Increases in mortality were also observed and the associated economic burden calculated. Despite the elevated construction and operation costs of the subway, when environment and social values are considered, cost-benefit analysis results would indicate a worthwhile investment. The consideration of these aspects is essential to sustainable transportation analyses, and in the case of the São Paulo subway, our analysis clearly demonstrated the important role of this system in the city's environmental, social and economic attributes.

    A major public health crisis facing America's society is the increase in child and youth obesity, which has seen a fourfold increase in the last four decades. Major concerns include what children eat for school lunch and what other foods are available in schools. This paper illustrates efforts towards systems change in the luncheon program and food vending machines in the Chicago Public Schools. We discuss the different factors that lead to such changes using the framework of the social ecological model and the soft systems methodology, and we analyze how the resulting innovation was implemented and evaluated. First, we present a theoretical perspective to explain factors that influence children's eating patterns from a systems approach. Second, we discuss the antecedent factors that lead to systems change. Finally, we examine challenges to systems change, such as resistance to change, different stakeholder priorities, lack of resources, institutional bureaucracy, and unrealistic funder expectations.

    In order to understand the current status of rainwater harvesting (RWH) practices in Taiwan's schools, a study was carried out to examine the RWH system performance, water usage, and water quality in these sites. A total of 29 schools in various regions were selected for this investigation, including 7 in the northern, 7 in the central, 8 in the southern, and 7 in the eastern regions of Taiwan. Water quality indicators tested were: pH, temperature, conductivity, oxidation-reduction potential, suspended solid, total organic carbon, fecal coliform, and total coliform. From this study, it was found that RWH systems in these sites generally had two different designs: one that collected rainwater only, and one that collected both rainwater and grey water. From statistical analysis, it was found that water quality indicators such as suspended solids, total organic carbon, and fecal coliform were significantly affected by the water source and site location. Fecal coliforms in most of the sites we studied were high and not qualified for toilet flushing. The average water retention time of 2.4 months was long and considered to be the main reason to cause high fecal coliform counts. Finally, the benefit analysis was conducted to evaluate economic feasibility of rainwater harvesting for these schools. It turned out that 20% of them were able to gain economic benefits from using rainwater.

  15. A Typology of Benefit Sharing Arrangements for the Governance of Social-Ecological Systems in Developing Countries

    Directory of Open Access Journals (Sweden)

    Charles Breen

    2012-03-01

    Full Text Available This study explores and interprets relevant literature to construct a typology of benefit sharing arrangements for the governance of social-ecological systems in developing countries. The typology comprises three generic categories of benefit sharing arrangements: collaborative, market-oriented, and egalitarian. We contend that the three categories provide a useful basis for exploring and classifying the different societal arrangements required for governance of social-ecological systems. The typology we present is founded on a related set of explicit assumptions that can be used to explore and better understand the linkages among ecosystem services, benefit sharing, and governance. Issues that are strongly related to sustainability in developing countries form the core basis of our assumptions. Our aim is not to write a definitive exposition, but to spark debate and engage ongoing dialogue on governance and benefit sharing in the field of social-ecological systems.

  2. Projected Benefits of New Residential Evaporative Cooling Systems: Progress Report #2

    Energy Technology Data Exchange (ETDEWEB)

    2006-10-01

    The use of conventional evaporative cooling has rapidly declined in the United States despite the fact that it has high potential for energy savings in dry climates. Evaporative systems are very competitive in terms of first cost and provide significant reductions in operating energy use, as well as peak-load reduction benefits. Significant market barriers still remain and can be addressed through improved systems integration. This report investigates the first of these approaches, exploring innovative components. The U.S. Department of Energy (DOE) Building America research teams are investigating the use of two promising new pieces of residential cooling equipment that employ evaporative cooling as a part of their system design. The OASys unit, which is a combination of direct and indirect evaporative cooling stages developed by Davis Energy Group (DEG) and manufactured by Speakman CRS, is used to ultimately provide outside air to the living space. The outdoor air provided is indirectly and directly evaporatively cooled in two stages to a condition that can be below the wet-bulb (wb) temperature of the outside air, thus outperforming a conventional single-stage direct evaporative cooler.

  3. The Impact of Systemic Risk on the Diversification Benefits of a Risk Portfolio

    Directory of Open Access Journals (Sweden)

    Marc Busse

    2014-07-01

    Full Text Available Risk diversification is the basis of insurance and investment. It is thus crucial to study the effects that could limit it. One of them is the existence of systemic risk that affects all of the policies at the same time. We introduce here a probabilistic approach to examine the consequences of its presence on the risk loading of the premium of a portfolio of insurance policies. This approach could be easily generalized for investment risk. We see that, even with a small probability of occurrence, systemic risk can reduce dramatically the diversification benefits. It is clearly revealed via a non-diversifiable term that appears in the analytical expression of the variance of our models. We propose two ways of introducing it and discuss their advantages and limitations. By using both VaR and TVaR to compute the loading, we see that only the latter captures the full effect of systemic risk when its probability to occur is low.

    2014-01-01

    In this study, we investigated whether the Agr communication system of the pathogenic bacterium Listeria monocytogenes was involved in adaptation and competitiveness in soil. Alteration of the ability to communicate, either by deletion of the gene coding the response regulator AgrA (response-negative mutant) or the signal pro-peptide AgrD (signal-negative mutant), did not affect population dynamics in soil that had been sterilized but survival was altered in biotic soil suggesting that the Agr system of L. monocytogenes was involved to face the complex soil biotic environment. This was confirmed by a set of co-incubation experiments. The fitness of the response-negative mutant was lower either in the presence or absence of the parental strain but the fitness of the signal-negative mutant depended on the strain with which it was co-incubated. The survival of the signal-negative mutant was higher when co-cultured with the parental strain than when co-cultured with the response-negative mutant. These results showed that the ability to respond to Agr communication provided a benefit to listerial cells to compete. These results might also indicate that in soil, the Agr system controls private goods rather than public goods.

  5. Industry survey of space system cost benefits from New Ways Of Doing Business

    Rosmait, Russell L.

    1992-01-01

    The cost of designing, building and operating space system hardware has always been expensive. Small quantities of specialty parts escalate engineering design, production and operations cost. Funding cutbacks and shrinking revenues dictate aggressive cost saving programs. NASA's highest priority is providing economical transportation to and from space. Over the past three decades NASA has seen technological advances that provide grater efficiencies in designing, building, and operating of space system hardware. As future programs such as NLS, LUTE and SEI begin, these greater efficiencies and cost savings should be reflected in the cost models. There are several New Ways Of Doing Business (NWODB) which, when fully implemented will reduce space system costs. These philosophies and/or culture changes are integrated in five areas: (1) More Extensive Pre-Phase C/D & E, (2) Multi Year Funding Stability, (3) Improved Quality, Management and Procurement Processes, (4) Advanced Design Methods, and (5) Advanced Production Methods. Following is an overview of NWODB and the Cost Quantification Analysis results using an industry survey, one of the four quantification techniques used in the study. The NWODB Cost Quantification Analysis is a study performed at Marshall Space Flight Center by the Engineering Cost Group, Applied Research Incorporated and Pittsburg State University. This study took place over a period of four months in mid 1992. The purpose of the study was to identify potential NWODB which could lead to improved cost effectiveness within NASA and to quantify potential cost benefits that might accrue if these NWODB were implemented.

  6. An Inclusive School Choir for Children with Autism in Israel: Using Grounded Theory to Explore the Perceived Benefits and Challenges

    Directory of Open Access Journals (Sweden)

    Yael Eilat

    2016-03-01

    Full Text Available This study examined the role and place of an inclusive children’s choir in Israel for children with autism and neurotypical children. 16 individuals participated in the study, including ten staff members from a school for children with autism, four staff members from a mainstream school, two eleven-year old girls from the mainstream school who sang in the choir, and four parents from both schools whose children sang in the choir. The study utilized grounded theory with purposive sampling and semi-structured interviews. Categorical analysis of the data was used. The description of the results demonstrates that the programme filled six major roles: musical, social, educational, cultural, emotional, and inclusive; although there were challenges to this inclusive music making opportunity. In addition, we found that an inclusive choir can change its participants’ social perceptions of the “other”. Its success is dependent on the administration’s positive attitude, cooperation of educational staff from both schools – mainstream and special education – and the sensitivity of the choir’s conductor.

    2015-12-01

    We present here a simple analysis of both the cost and the benefit of using the cloud in environmental science circa 2016. We present this set of ideas to enable the potential 'cloud adopter' research scientist to explore and understand the tradeoffs in moving some aspect of their compute work to the cloud. We present examples, design patterns and best practices as an evolving body of knowledge that help optimize benefit to the research team. Thematically this generally means not starting from a blank page but rather learning how to find 90% of the solution to a problem pre-built. We will touch on four topics of interest. (1) Existing cloud data resources (NASA, WHOI BCO DMO, etc) and how they can be discovered, used and improved. (2) How to explore, compare and evaluate cost and compute power from many cloud options, particularly in relation to data scale (size/complexity). (3) What are simple / fast 'Lightweight Data System' procedures that take from 20 minutes to one day to implement and that have a clear immediate payoff in environmental data-driven research. Examples include publishing a SQL Share URL at (EarthCube's) CINERGI as a registered data resource and creating executable papers on a cloud-hosted Jupyter instance, particularly iPython notebooks. (4) Translating the computational terminology landscape ('cloud', 'HPC cluster', 'hadoop', 'spark', 'machine learning') into examples from the community of practice to help the geoscientist build or expand their mental map. In the course of this discussion -- which is about resource discovery, adoption and mastery -- we provide direction to online resources in support of these themes.

  9. The Benefits of Internalizing Air Quality and Greenhouse Gas Externalities in the US Energy System

    Science.gov (United States)

    Brown, Kristen E.

    The emission of pollutants from energy use has effects on both local air quality and the global climate, but the price of energy does not reflect these externalities. This study aims to analyze the effect that internalizing these externalities in the cost of energy would have on the US energy system, emissions, and human health. In this study, we model different policy scenarios in which fees are added to emissions related to generation and use of energy. The fees are based on values of damages estimated in the literature and are applied to upstream and combustion emissions related to electricity generation, industrial energy use, transportation energy use, residential energy use, and commercial energy use. The energy sources and emissions are modeled through 2055 in five-year time steps. The emissions in 2045 are incorporated into a continental-scale atmospheric chemistry and transport model, CMAQ, to determine the change in air quality due to different emissions reduction scenarios. A benefit analysis tool, BenMAP, is used with the air quality results to determine the monetary benefit of emissions reductions related to the improved air quality. We apply fees to emissions associated with health impacts, climate change, and a combination of both. We find that the fees we consider lead to reductions in targeted emissions as well as co-reducing non-targeted emissions. For fees on the electric sector alone, health impacting pollutant (HIP) emissions reductions are achieved mainly through control devices while Greenhouse Gas (GHG) fees are addressed through changes in generation technologies. When sector specific fees are added, reductions come mainly from the industrial and electricity generation sectors, and are achieved through a mix of energy efficiency, increased use of renewables, and control devices. Air quality is improved in almost all areas of the country with fees, including when only GHG fees are applied. Air quality tends to improve more in regions with

  10. Probiotics in the Space Food System: Delivery, Microgravity Effects, and the Potential Benefit to Crew Health

    Science.gov (United States)

    Castro, S. L.; Ott, C. M.; Douglas, G. L.

    2014-01-01

    As mission distance and duration increase, the need grows for non-invasive disease prevention and immunomodulation, especially given the limited medical response capability expected for these missions and the immune dysregulation documented in crew. Additionally, changes in diet, lifestyle, antibiotic usage, and the environmental stresses during spaceflight may alter crewmembers' intestinal microbiome. The addition of probiotic bacteria to the space food system is expected to confer immunostimulatory benefits on crewmembers, with the potential to counteract the immune dysregulation that has been documented in spaceflight. Based on previous studies that demonstrated unique microbiological responses to the low shear environment of spaceflight, probiotic organisms hold the potential to induce enhanced beneficial responses through mechanisms, such as beneficial interactions with human immune cells and repression of colonization of pathogens on the mucosa. The work presented here will begin to address two research gaps related to providing probiotics in spaceflight: 1) delivery, and 2) the effect of the low shear microgravity environment on probiotic attributes. The probiotic Lactobacillus acidophilus was selected for investigation due to its wide commercial use and documented benefits that include inhibition of virulence related gene expression in pathogens and mucosal stimulation of immune cells. The delivery system for probiotics has not been determined for spaceflight, where the food system is shelf stable and the lack of refrigeration prevents the use of traditional dairy delivery methods. In order to demonstrate the potential of the space food system to deliver viable probiotic bacteria to crewmembers, the probiotic L. acidophilus was packaged in high barrier flight packaging in nonfat dry milk (NFDM) or retained in commercial capsule form. Viable cells were enumerated over 8 months of storage at 22, 4, and -80ºC. The survival of L. acidophilus rehydrated in NFDM

    2004-12-01

    This Guide describes a high level, technology-neutral framework for assessing potential benefits from and economic market potential for energy storage used for electric utility-related applications. In the United States use of electricity storage to support and optimize transmission and distribution (T&D) services has been limited due to high storage system cost and by limited experience with storage system design and operation. Recent improvement of energy storage and power electronics technologies, coupled with changes in the electricity marketplace, indicate an era of expanding opportunity for electricity storage as a cost-effective electric resource. Some recent developments (in no particular order) that drive the opportunity include: (1) states adoption of the renewables portfolio standard (RPS), which may increased use of renewable generation with intermittent output, (2) financial risk leading to limited investment in new transmission capacity, coupled with increasing congestion on some transmission lines, (3) regional peaking generation capacity constraints, and (4) increasing emphasis on locational marginal pricing (LMP).

    Fernández-Alemán, José Luis; García, Ana Belén Sánchez; Montesinos, María José López; Jiménez, Juan José López

    2014-05-01

    This article presents an empirical study on the effectiveness of the use of an audience response system called SIstema De Respuesta inmediata de la Audiencia on a nursing course. A total of 130 students of mixed gender, age, and computer experience and educational background on a third-year course in nursing administration and management participated in the study. The benefits of an audience response system as regards learning how to confront emergency situations were studied. The innovative aspect of the proposal is twofold: (1) the use of a smartphone to respond to the questions and (2) the analysis of the students' response time when confronting critical situations while managing nursing resources. A positive impact on the students' performance was revealed in their final assessments. Our findings show that SIstema De Respuesta inmediata de la Audiencia increases student participation and aids in identifying and correcting misconceptions. The students found SIstema De Respuesta inmediata de la Audiencia to be very motivating and wanted it to be used in additional lectures. Further research is required to study the effectiveness of SIstema De Respuesta inmediata de la Audiencia for it to be widely used in other disciplines.

    Full Text Available The present study deals with initial formation of concept of decimal system in second year of education at primary school in Mexico (City of Puebla. Our research is based on Activity Theory conception of teaching-learning process and of gradual introduction of scientific concepts in school age. The method has been designed and worked out with the help of actions in which logic, symbolic, spatial and mathematical aspects were implemented. All actions were introduced within divided activity of children in group guided by adult. A pretest-posttest design was used with an experimental group of Mexican school children. The results showed that children have developed the significant skills necessary for understanding the concept of decimal number system. They were also able to apply this concept for new kind if activity al the end of school year. Such new activity was solving of mathematic problems, which was not included in official school program. We consider that proposed method can be an approximation for solution of common difficulties which arise at primary school concerning teaching of mathematics.

    2016-07-01

    Full Text Available School technology integration rarely begins with school or educator choice. It is part of a wider context where external and internal factors have direct influence on the goals and tools that are adopted over time. The objective of this study is to investigate the systemic conditions that contribute or inhibit the development of different activities by teachers making use of new media. We compiled a list of well-known conditions for technology integration success and mapped these in the historical and culturally bound perspective of activity theory (cultural historical activity theory. We conducted a multiple case study analysis of four schools, public and private. The results point to unique and distinctive scenarios even when homogeneity would be expected, reinforcing the argument that material conditions do not determine pedagogical outcomes nor do they determine changes in practice. Beyond this, the study proposes a methodology that can help elicit tensions in technology integration, pointing to avenues for school development.

    2013-03-01

    This paper presents a cross-disciplinary framework for assessment of climate change adaptation to increased precipitation extremes considering pluvial flood risk as well as additional environmental services provided by some of the adaptation options. The ability of adaptation alternatives to cope with extreme rainfalls is evaluated using a quantitative flood risk approach based on urban inundation modeling and socio-economic analysis of corresponding costs and benefits. A hedonic valuation model is applied to capture the local economic gains or losses from more water bodies in green areas. The framework was applied to the northern part of the city of Aarhus, Denmark. We investigated four adaptation strategies that encompassed laissez-faire, larger sewer pipes, local infiltration units, and open drainage system in the urban green structure. We found that when taking into account environmental amenity effects, an integration of open drainage basins in urban recreational areas is likely the best adaptation strategy, followed by pipe enlargement and local infiltration strategies. All three were improvements compared to the fourth strategy of no measures taken.

    Mindfulness is known to decrease psychological distress. Possible benefits in pregnancy have rarely been explored. Our aim was to examine the prospective association of mindfulness with autonomic nervous system function during pregnancy and with later infant social-emotional development. Pregnant women (N = 156) completed self-report mindfulness and emotional distress questionnaires, and had their autonomic function assessed in their first and third trimesters, including heart rate (HR), indices of heart rate variability (HRV), preejection period (PEP), and systolic (SBP) and diastolic blood pressure (DBP). The social-emotional development of 109 infants was assessed at 4 months of age. More mindful pregnant women had less prenatal and postnatal emotional distress (p mindful mothers, parasympathetic activity decreased less (RMSSD: p = .01; HF HRV: p = .03) and sympathetic activity (inversely related to PEP) increased less (PEP: p = .02) between trimesters. Their offspring displayed less negative social-emotional behavior (p = .03) compared to offspring of less mindful mothers. Mindfulness in pregnancy was associated with ANS changes likely to be adaptive and with better social-emotional offspring development. Interventions to increase mindfulness during pregnancy might improve maternal and offspring health, but randomized trials are needed to demonstrate this.

    Full Text Available About 100 teachers participated in a study and helped to understand how new reforms are faced by those who work in the field, in the particular case of the discipline of geography. The study that was done with geography teachers after 10 years of national curriculum revealed many gaps in terms of what teachers are expected to do. Only recently, some legislation has been issued to regulate the kind of training teachers do as they progress in their teaching careers. The national curriculum for basic education is a huge step in terms of being a part of the world agenda in what concerns a modern teaching and a new vision of what schools should prepare students to, but the instruments of that change (teachers have been neglected.

    , it is necessary to identify necessary procedures, in order to ensure fulfillment of all requirements. The aim is to establish an optimal system using as few procedures as posible. Therefore, it is necessary to choose first few procedures very carefully and implement them so that emloyees gain confidence. Procedures must be defined in such a way that they determine activities and responsibilities for particular jobs. Drawing up instructions and records Work instructions are documents that describe a way of accomplishing activities defined by procedures. Based on them, every competent executor would be able to complete a determined job. Records are documents that give objective evidence that a quality management system entirely conforms with standard requirements. As opposed to procedures, they are unchangeable and they record what was done, who did what, how something was done, and what was achieved. Implementation and control of a quality management system Implementing a quality management system opens a new process of system monitoring, reevalutation and improvement, thus entering first into a process of internal auditing. Internal audits have a purpose of marking positions at which the process in unsuccessful, of detecting deviations and improving the system. Certification Positive experience shows that a certification institution should be chosen at least three months before a formal evaluation is planned. Also, it is very important to choose a certification institution which is accepted, recognized and entirely accredited (BSI, LRQA, TÜV SUD, SGS, Bureau Veritas, etc.. Ther is no certification body that has total accreditation, but only accredited fields in which they can demonstrate relevant experience. Impact and benefits of the establishment of ISO 9001 system Entering the process of certification indicates commitment to quality, which reflects in lower costs due to fewer nonconformed products, lfewer refused products as well as in fewer faults in general

  16. Benefits of assimilating thin sea ice thickness from SMOS into the TOPAZ system

    An observation product for thin sea ice thickness (SMOS-Ice) is derived from the brightness temperature data of the European Space Agency's (ESA) Soil Moisture and Ocean Salinity (SMOS) mission. This product is available in near-real time, at daily frequency, during the cold season. In this study, we investigate the benefit of assimilating SMOS-Ice into the TOPAZ coupled ocean and sea ice forecasting system, which is the Arctic component of the Copernicus marine environment monitoring services. The TOPAZ system assimilates sea surface temperature (SST), altimetry data, temperature and salinity profiles, ice concentration, and ice drift with the ensemble Kalman filter (EnKF). The conditions for assimilation of sea ice thickness thinner than 0.4 m are favorable, as observations are reliable below this threshold and their probability distribution is comparable to that of the model. Two parallel Observing System Experiments (OSE) have been performed in March and November 2014, in which the thicknesses from SMOS-Ice (thinner than 0.4 m) are assimilated in addition to the standard observational data sets. It is found that the root mean square difference (RMSD) of thin sea ice thickness is reduced by 11 % in March and 22 % in November compared to the daily thin ice thicknesses of SMOS-Ice, which suggests that SMOS-Ice has a larger impact during the beginning of the cold season. Validation against independent observations of ice thickness from buoys and ice draft from moorings indicates that there are no degradations in the pack ice but there are some improvements near the ice edge close to where the SMOS-Ice has been assimilated. Assimilation of SMOS-Ice yields a slight improvement for ice concentration and degrades neither SST nor sea level anomaly. Analysis of the degrees of freedom for signal (DFS) indicates that the SMOS-Ice has a comparatively small impact but it has a significant contribution in constraining the system (> 20 % of the impact of all ice and ocean

    Gibson, Wayne H.; Levesque, Daniel

    2000-03-01

    This paper discusses how gamma irradiation plants are putting the latest advances in computer and information technology to use for better process control, cost savings, and strategic advantages. Some irradiator operations are gaining significant benefits by integrating computer technology and robotics with real-time information processing, multi-user databases, and communication networks. The paper reports on several irradiation facilities that are making good use of client/server LANs, user-friendly graphics interfaces, supervisory control and data acquisition (SCADA) systems, distributed I/O with real-time sensor devices, trending analysis, real-time product tracking, dynamic product scheduling, and automated dosimetry reading. These plants are lowering costs by fast and reliable reconciliation of dosimetry data, easier validation to GMP requirements, optimizing production flow, and faster release of sterilized products to market. There is a trend in the manufacturing sector towards total automation using "predictive process control". Real-time verification of process parameters "on-the-run" allows control parameters to be adjusted appropriately, before the process strays out of limits. Applying this technology to the gamma radiation process, control will be based on monitoring the key parameters such as time, and making adjustments during the process to optimize quality and throughput. Dosimetry results will be used as a quality control measurement rather than as a final monitor for the release of the product. Results are correlated with the irradiation process data to quickly and confidently reconcile variations. Ultimately, a parametric process control system utilizing responsive control, feedback and verification will not only increase productivity and process efficiency, but can also result in operating within tighter dose control set points.

    2014-09-01

    This report outlines the methods, data, and tools that could be used at different levels of sophistication and effort to estimate the benefits and costs of DGPV. In so doing, we identify the gaps in current benefit-cost-analysis methods, which we hope will inform the ongoing research agenda in this area. The focus of this report is primarily on benefits and costs from the utility or electricity generation system perspective. It is intended to provide useful background information to utility and regulatory decision makers and their staff, who are often being asked to use or evaluate estimates of the benefits and cost of DGPV in regulatory proceedings. Understanding the technical rigor of the range of methods and how they might need to evolve as DGPV becomes a more significant contributor of energy to the electricity system will help them be better consumers of this type of information. This report is also intended to provide information to utilities, policy makers, PV technology developers, and other stakeholders, which might help them maximize the benefits and minimize the costs of integrating DGPV into a changing electricity system.

    1997-12-01

    During the period 1994-95, solar photovoltaic systems were installed at a number of schools in Neuquen Province, Argentina, by the Provincial electric utility, Ente Provincial de Energia del Neuquen. This was undertaken with funds provided by the Inter-American Development Bank. In all, there are 12 schools that have had photovoltaic generating systems installed. These generating systems are designed to provide electricity for the basic needs at the schools: primarily for lighting, and to operate small electrical appliances such as communication radios, televisions, VCR`s, AM/FM and short-wave radios. They do not provide enough energy to operate large consumption appliances such as washing machines, microwaves, refrigerators, power tools, etc. The program of provision of PV systems was supplemented with training on simple systems for cooking food or drying fruit, etc. These techniques are primarily intended for demonstration at the schools thus serving an educational role with the hope that they will be transmitted in time to the families of the students where the need is manifested the most.

    Full Text Available Objective: There is a research gap in studies that evaluate the effectiveness of a school-embedded mindfulness-based intervention for both students and teachers. To address this gap, the present pilot study reviews relevant literature and investigates whether students and teachers who participate in separate Mindfulness-Based Stress Reduction (MBSR courses show improvements across a variety of psychological variables including areas of mental health and creativity. Methods: The study applied a controlled waitlist design with three measurement points. A total of 29 students (n = 15 in the intervention and n = 14 in the waitlist group and 29 teachers (n = 14 in the intervention and n = 15 in the waitlist group completed questionnaires before and after the MBSR course. The intervention group was also assessed after a four-month follow-up period. Results: Relative to the control group, significant improvements in self-reported stress, self-regulation, school-specific self-efficacy and interpersonal problems were found among the students who participated in the MBSR course (p < .05, Cohens` d ranges from 0.62-0.68. Medium effect sizes on mindfulness, anxiety and creativity indicate a realistic potential in those areas. By contrast, teachers in the intervention group showed significantly higher self-reported mindfulness levels and reduced interpersonal problems compared to the control group(p < .05, Cohens` d = 0.66 and 0.42, respectively, with medium effect sizes on anxiety and emotion regulation. Conclusion: The present findings contribute to a growing body of studies investigating mindfulness in schools by discussing the similarities and differences in the effects of MBSR on students and teachers as well as stressing the importance of investigating interpersonal effects.

  5. Digital dissection system for medical school anatomy training

    2003-05-01

    As technology advances, new and innovative ways of viewing and visualizing the human body are developed. Medicine has benefited greatly from imaging modalities that provide ways for us to visualize anatomy that cannot be seen without invasive procedures. As long as medical procedures include invasive operations, students of anatomy will benefit from the cadaveric dissection experience. Teaching proper technique for dissection of human cadavers is a challenging task for anatomy educators. Traditional methods, which have not changed significantly for centuries, include the use of textbooks and pictures to show students what a particular dissection specimen should look like. The ability to properly carry out such highly visual and interactive procedures is significantly constrained by these methods. The student receives a single view and has no idea how the procedure was carried out. The Department of Anatomy at Mayo Medical School recently built a new, state-of-the-art teaching laboratory, including data ports and power sources above each dissection table. This feature allows students to access the Mayo intranet from a computer mounted on each table. The vision of the Department of Anatomy is to replace all paper-based resources in the laboratory (dissection manuals, anatomic atlases, etc.) with a more dynamic medium that will direct students in dissection and in learning human anatomy. Part of that vision includes the use of interactive 3-D visualization technology. The Biomedical Imaging Resource (BIR) at Mayo Clinic has developed, in collaboration with the Department of Anatomy, a system for the control and capture of high resolution digital photographic sequences which can be used to create 3-D interactive visualizations of specimen dissections. The primary components of the system include a Kodak DC290 digital camera, a motorized controller rig from Kaidan, a PC, and custom software to synchronize and control the components. For each dissection procedure, the

Therefore, the geographical perspective on the waterscape concept proposes a search apart from one solution or best practice as, in our assumption, there are no single best answers because the human dimension and their action and reaction are guided also beyond perceptions, preferences, benefits and costs. Our waterscape concept allows a multi-spatial and multi-disciplinary perspective on water and its projection into space by acknowledging multiple meanings, alternative framings and possible development paths, hence fostering an integrative perspective on human-water systems. It further provides a fruitful framework for transdisciplinary research approaches since it is open and supports societal co-production and reframing of knowledge and policies. Troy, T.

    2014-07-01

    Full Text Available Background: The benefits of Health and Demographic Surveillance sites for local populations have been the topic of discussion as countries such as Ethiopia take efforts to achieve their Millennium Development Goal targets, on which they lag behind. Ethiopia's maternal mortality ratio is very high, and in the 2011 Ethiopia Demographic and Health Survey (2011 EDHS it was estimated to be 676/100,000 live births. Recent Global Burden of Disease (GBD and estimates based on the United Nations model reported better, but still unacceptably high, figures of 497/100,000 and 420/100,000 live births for 2013. In the 2011 EDHS, antenatal care (ANC utilization was estimated at 34%, and delivery in health facilities was only 10%. Objectives: To compare maternal health service utilization among populations in a Health and Demographic Surveillance System (HDSS to non-HDSS populations in Butajira district, south central Ethiopia. Design: A community-based comparative cross-sectional study was conducted in January and February 2012 among women who had delivered in the 2 years before the survey. Results: A total of 2,296 women were included in the study. One thousand eight hundred and sixty two (81.1% had attended ANC at least once, and 37% of the women had attended ANC at least four times. A quarter of the women delivered their last child in a health facility. Of the women living outside the HDSS areas, 715 (75.3% attended ANC at least once compared to 85.1% of women living in the HDSS areas [adjusted odds ratio (AOR 0.59; 95% CI 0.46, 0.74]. Of the women living outside the HDSS areas, only 170 (17.9% delivered in health facilities and were assisted by skilled attendants during delivery, whereas 30.0% of those living in HDSS areas delivered in health facilities (AOR 0.66; 95% CI 0.48, 0.91. Conclusion: This paper provides possible evidence that living in an HDSS site has a positive influence on maternal health. In addition, there may be a positive influence on

    An experiment upon an agri-silvicultural system involving Willow (Salix alba) tree,Kale (Brassica oleracea var.acephala) and Knol khol (Brassica oleracea var.caularapa) was laid in randomized block designed at farmers' willow field at Shalimar near Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir,Srinagar India during 2005 and 2006.The main plot was divided into sub-spots with 8 m ( 2 m in size each in which four two-year-old willow (Salix alba) trees were at a spacing of 2 m ( 2 m in a sub-spot.The intercrops were maintained at recommended spacing and supplied with recommended doses of fertilizers.The benefit-cost ratio in willow plantation intercropped with vegetable crops of Kale and Knol Khol was analyzed and compared with the benefit-cost ratio of sole willow tree forestry.The results showed that every rupee invested in plantation of agri-silvicultural system generates benefit-cost ratio of 2.78 and 2.79 in case of Willow intercropping with Kale and Willow with Knol khol,respectively,while as for sole crop of willows benefit-cost ratio was calculated to be 2.66.These results provided circumstantial evidence in favour of adopting agroforestry involving willow instead of Sole tree forestry.

  2. Making authentic science accessible—the benefits and challenges of integrating bioinformatics into a high-school science curriculum

    2017-01-01

    Despite the central place held by bioinformatics in modern life sciences and related areas, it has only recently been integrated to a limited extent into high-school teaching and learning programs. Here we describe the assessment of a learning environment entitled ‘Bioinformatics in the Service of Biotechnology’. Students’ learning outcomes and attitudes toward the bioinformatics learning environment were measured by analyzing their answers to questions embedded within the activities, questionnaires, interviews and observations. Students’ difficulties and knowledge acquisition were characterized based on four categories: the required domain-specific knowledge (declarative, procedural, strategic or situational), the scientific field that each question stems from (biology, bioinformatics or their combination), the associated cognitive-process dimension (remember, understand, apply, analyze, evaluate, create) and the type of question (open-ended or multiple choice). Analysis of students’ cognitive outcomes revealed learning gains in bioinformatics and related scientific fields, as well as appropriation of the bioinformatics approach as part of the students’ scientific ‘toolbox’. For students, questions stemming from the ‘old world’ biology field and requiring declarative or strategic knowledge were harder to deal with. This stands in contrast to their teachers’ prediction. Analysis of students’ affective outcomes revealed positive attitudes toward bioinformatics and the learning environment, as well as their perception of the teacher’s role. Insights from this analysis yielded implications and recommendations for curriculum design, classroom enactment, teacher education and research. For example, we recommend teaching bioinformatics in an integrative and comprehensive manner, through an inquiry process, and linking it to the wider science curriculum. PMID:26801769

  8. The indigenous and the imported: The New Zealand school system

    Science.gov (United States)

    Snook, Ivan

    1990-06-01

    New Zealand (Aotearoa) was colonized from Britain and the colonizers imposed on the indigenous Maori people a foreign view of education. From then on tradition has vied with local adaptations to produce a school system with substantial traces of the `Old Country' but with many local features. The curriculum for boys continued to dominate, with that for girls struggling to make itself felt. There has been constant debate about `basics' and `frills' though these terms have not been clearly defined. More recently there has been more serious consideration of the curriculum but this has been overtaken by a `market forces' view of schooling. A new administration system comes into operation on 1st October 1989. The future is unclear but it is reasonable to hope that there will continue a dialectic which may one day produce a genuine synthesis suited to the multicultural nature of Aotearoa.

  9. Electronic medical record systems in critical access hospitals: leadership perspectives on anticipated and realized benefits.

    Science.gov (United States)

    Mills, Troy R; Vavroch, Jared; Bahensky, James A; Ward, Marcia M

    2010-04-01

    The growth of electronic medical records (EMRs) is driven by the belief that EMRs will significantly improve healthcare providers' performance and reduce healthcare costs. Evidence supporting these beliefs is limited, especially for small rural hospitals. A survey that focused on health information technology (HIT) capacity was administered to all hospitals in Iowa. Structured interviews were conducted with the leadership at 15 critical access hospitals (CAHs) that had implemented EMRs in order to assess the perceived benefits of operational EMRs. The results indicate that most of the hospitals implemented EMRs to improve efficiency, timely access, and quality. Many CAH leaders also viewed EMR implementation as a necessary business strategy to remain viable and improve financial performance. While some reasons reflect external influences, such as perceived future federal mandates, other reasons suggest that the decision was driven by internal forces, including the hospital's culture and the desires of key leaders to embrace HIT. Anticipated benefits were consistent with goals; however, realized benefits were rarely obvious in terms of quantifiable results. These findings expand the limited research on the rationale for implementing EMRs in critical access hospitals.

    2011-01-01

    Full Text Available This paper presents a systematical evaluation experience on the performance and economic studies of line arresters for a 69 kV transmission system in Taiwan. The transient over-voltage phenomenon in high voltage transmission lines under lightning by using the Electro-Magnetic Transients Program (EMTP package is well modeled and analyzed. The modeling for the simulated system including lightning, transmission line, transmission tower and line arrester are all considered to have more practical results. The cost and benefit evaluation for line arresters installation  is then conducted to provide a reasonable suggestion for lightning protection.  The performance of line arresters is evaluated by considering different installation schemes and lightning currents. Finally, a Taiwan’s experience is illustrated from both of the cost and benefit points of view.

    The International Summer School on Mathematical Systems Theory and Economics was held at the Villa Monastero in Varenna, Italy, from June 1 through June 12, 1967. The objective of this Summer School was to review the state of the art and the prospects for the application of the mathematical theory of systems to the study and the solution of economic problems. Particular emphasis was given to the use of the mathematical theory of control for the solution of problems in economics. It was felt that the publication of a volume collecting most of the lectures given at the school would show the current status of the application of these methods. The papers are organized into four sections arranged into two volumes: basic theories and optimal control of economic systems which appear in the first volume, and special mathematical problems and special applications which are contained in the second volume. Within each section the papers follow in alphabetical order by author. The seven papers on basic theories are a rat...

    Hill, Heather K; Stewart, Denice C L; Ash, Joan S

    2010-04-01

    The purpose of this study was to increase our understanding of the impact of Health Information Technology Systems (HITS) on dental school users when the systems are integrated into chair-side patient care. We used qualitative research methods, including interviews, focus groups, and observations, to capture the experiences of HITS users at a single institution. Users included administrators, clinical faculty members, predoctoral students, support staff, and residents. The data were analyzed using a grounded theory approach, and nine themes emerged: 1) HITS benefits were disproportionate among users; 2) communicating about the HITS was challenging; 3) users experienced a range of strong emotions; 4) the instructor persona diminished; 5) there were shifts in the school's power structure; 6) allocation of end-users' time shifted; 7) the training and support needs of end-users were significant; 8) perceived lack of HITS usability made documentation cumbersome for clinicians; and 9) clinicians' workflow was disrupted. HITS integration into patient care impacts the work of all system users, especially end-users. The themes highlight areas of potential concern for implementers and users in integrating a HITS into patient care.

    The purpose of this project was to evaluate the ability of advanced low rank coal gasification technology to cause a significant reduction in the COE for IGCC power plants with 90% carbon capture and sequestration compared with the COE for similarly configured IGCC plants using conventional low rank coal gasification technology. GE’s advanced low rank coal gasification technology uses the Posimetric Feed System, a new dry coal feed system based on GE’s proprietary Posimetric Feeder. In order to demonstrate the performance and economic benefits of the Posimetric Feeder in lowering the cost of low rank coal-fired IGCC power with carbon capture, two case studies were completed. In the Base Case, the gasifier was fed a dilute slurry of Montana Rosebud PRB coal using GE’s conventional slurry feed system. In the Advanced Technology Case, the slurry feed system was replaced with the Posimetric Feed system. The process configurations of both cases were kept the same, to the extent possible, in order to highlight the benefit of substituting the Posimetric Feed System for the slurry feed system.

  18. Optimal Sizing of a Solar-Plus-Storage System For Utility Bill Savings and Resiliency Benefits: Preprint

    2016-11-01

    Solar-plus-storage systems can achieve significant utility savings in behind-the-meter deployments in buildings, campuses, or industrial sites. Common applications include demand charge reduction, energy arbitrage, time-shifting of excess photovoltaic (PV) production, and selling ancillary services to the utility grid. These systems can also offer some energy resiliency during grid outages. It is often difficult to quantify the amount of resiliency that these systems can provide, however, and this benefit is often undervalued or omitted during the design process. We propose a method for estimating the resiliency that a solar-plus-storage system can provide at a given location. We then present an optimization model that can optimally size the system components to minimize the lifecycle cost of electricity to the site, including the costs incurred during grid outages. The results show that including the value of resiliency during the feasibility stage can result in larger systems and increased resiliency.

    Yousuf, Basharat; Gul, Khalid; Wani, Ali Abas; Singh, Preeti

    2016-10-01

    Anthocyanins are one of the six subgroups of large and widespread group of plant constituents known as flavonoids. These are responsible for the bright and attractive orange, red, purple, and blue colors of most fruits, vegetables, flowers and some cereal grains. More than 600 structurally distinct anthocyanins have been identified in nature. Earlier, anthocyanins were only known for their coloring properties but now interest in anthocyanin pigments has intensified because of their possible health benefits as dietary antioxidants, which help to prevent neuronal diseases, cardiovascular illnesses, cancer, diabetes, inflammation, and many such others diseases. Ability of anthocyanins to counter oxidants makes them atherosclerosis fighters. Therefore, anthocyanin-rich foods may help to boost overall health by offering an array of nutrients. However, the incorporation of anthocyanins into food and medical products is a challenging task due to their low stability toward environmental conditions during processing and storage. Encapsulation seems to be an efficient way to introduce such compounds into these products. Encapsulating agents act as a protector coat against ambient adverse conditions such as light, humidity, and oxygen. Encapsulated bioactive compounds are easier to handle and offer improved stability. The main objective of this review is to explore health benefits of anthocyanins and their extraction, characterization, encapsulation, and delivery.

    2012-07-01

    Full Text Available This study compared the finishing performance carcass characteristics and economic benefits of two imported (Limousin and Simmental and three local (Luxi, Jinnan and Qinchuan cattle breeds slaughtered at 18.5 months of age under thetypical Chinese beef production system. All cattle (n=71 were reared under the same production system and fed the same finishing diet for 105 days. Eight bulls from each breed were randomly selected for slaughtering. Compared with the three local breeds, the two imported breeds had higher average daily gain, dry matter intake and gain efficiency. Regarding carcass characteristics, the two imported breeds had higher carcass weight, bone weight, net meat weight, and ribeye area (P<0.001. However, the local breeds had higher (P<0.01 marbling scores than the imported breeds. The imported breeds showed higher economic benefits (P<0.001 than the local breeds. In conclusion, the imported cattle breeds had better growth performance, carcass traits and economic benefits compared with the local cattle breeds at 18.5 months old under the typical Chinese feeding conditions whereas, in this study, the local breeds may have some advantage in terms of meat quality.

    2015-09-01

    Full Text Available This paper compares financial costs and benefits of floating rice-based and intensive rice farming systems using data from focus group discussions and household survey in four locations in the Mekong Delta. We argue that the net financial benefit per 1000m2 of integrated floating rice-based farming systems is greater than the net financial benefit of intensive rice farming system. The total net benefit of floating rice-leeks shows the highest net benefit (VND 24.8 mil./1000 m2, followed by floating rice-sweet corn- two baby corn crops and cattle systems (VND 18.5 mil./1000m2, and floating rice-chili (VND 16.7-17.7 mil./1000m2. If farmers cultivate monoculture of rice either two or three crops, the net benefits are ranging from VND 2.2-4.8 mil./1000m2 respectively. Alternatively, farmers integrate vegetables; the net benefit was ranging from VND 5.6 to 11.7 mil./1000m2. The net benefit of the two rice crops is lowest (VND 1.3-2.3 mil./1000m2. Surprisingly, if farmers convert from two intensive rice crops to two maize crops, the net benefit can reach to VND 21 million/1000m2. The results support the argument that the floating rice based systems allows farmers diversified into profitable upland crops, which can help farmers to improve their total income.

    Complicacy of clinical decisions justifies utilization of information systems such as artificial intelligence (e.g. expert systems and neural networks) to achieve better decisions, however, application of these systems in the medical domain faces some challenges. We aimed at to review the applications of these systems in the medical domain and discuss about such challenges. Following a brief introduction of expert systems and neural networks by representing few examples, the challenges of these systems in the medical domain are discussed. We found that the applications of expert systems and artificial neural networks have been increased in the medical domain. These systems have shown many advantages such as utilization of experts' knowledge, gaining rare knowledge, more time for assessment of the decision, more consistent decisions, and shorter decision-making process. In spite of all these advantages, there are challenges ahead of developing and using such systems including maintenance, required experts, inputting patients' data into the system, problems for knowledge acquisition, problems in modeling medical knowledge, evaluation and validation of system performance, wrong recommendations and responsibility, limited domains of such systems and necessity of integrating such systems into the routine work flows. We concluded that expert systems and neural networks can be successfully used in medicine; however, there are many concerns and questions to be answered through future studies and discussions.

  10. Potential Safety Benefit of the Blind Spot Detection System for Large Trucks on the Vulnerable Road Users in Taiwan

    Full Text Available Considering motorcyclists, pedestrians and bicyclists as vulnerable road users (VRUs, more than 75 percent of the victims of fatal crashes involving large trucks in Taiwan are VRUs. Most crashes occurred at or were due to the blind spots of large trucks because of the size and traveling locations of the VRUs. This study applies typology and statistical methods to estimate the potential safety benefit of blind spot detection (BSD systems for large trucks on VRUs. The pre-crash scenarios associated with the blind spots of large trucks were derived by counting the maneuvers of large trucks and VRUs, prior to crashes, the truck drivers’ improper behaviors (cause of crashes, and the crash types. The number of crashes and fatalities were counted for the pre-crash scenario relevant to the BSD systems. A value of 0.8 of human machine interface factor (HMIF based on a previous study was applied to estimate the potential safety benefits of the BSD system. The results show that the implementation of BSD systems on all large trucks could help avoid about 24, 10, and 11 percent of large truck-involved crashes with pedestrians, bicycles, and motorcycles, respectively. The BSD systems could also save 5 pedestrians, 3 bicyclists, and 15 motorcyclists per year from crashes involving large trucks.

  11. A cost-benefit analysis of preventative management for zebra and quagga mussels in the Colorado-Big Thompson System

    Zebra and quagga mussels are fresh water invaders that have the potential to cause severe ecological and economic damage. It is estimated that mussels cause $1 billion dollars per year in damages to water infrastructure and industries in the United States (Pimentel et al., 2004). Following their introduction to the Great Lakes in the late 1980s, mussels spread rapidly throughout the Mississippi River Basin and the Eastern U.S. The mussel invasion in the West is young. Mussels were first identified in Nevada in 2007, and have since been identified in California, Arizona, Colorado, Utah, and Texas. Western water systems are very different from those found in the East. The rapid spread of mussels through the eastern system was facilitated by connected and navigable waterways. Western water systems are less connected and are characterized by man-made reservoirs and canals. The main vector of spread for mussels in the West is overland on recreational boats (Bossenbroek et al., 2001). In response to the invasion, many western water managers have implemented preventative management programs to slow the overland spread of mussels on recreational boats. In Colorado, the Colorado Department of Wildlife (CDOW) has implemented a mandatory boat inspection program that requires all trailered boats to be inspected before launching in any Colorado water body. The objective of this study is to analyze the costs and benefits of the CDOW boat inspection program in Colorado, and to identify variables that affect the net benefits of preventative management. Predicting the potential economic benefits of slowing the spread of mussels requires integrating information about mussel dispersal potential with estimates of control costs (Keller et al., 2009). Uncertainty surrounding the probabilities of establishment, the timing of invasions, and the damage costs associated with an invasion make a simulation model an excellent tool for addressing "what if" scenarios and shedding light on the

    Activities in Physical Education Questionnaire (CAAFE. It also tells the main effects and which interactions produced gender, educational background, working status, teaching experience, type of courses completed, who taught the aquatic/water activity classes and the opinion of the general aspects of physical education about the inclusion of water activities in the school. The participants in the survey were one hundred and seventy-six ESO teachers from the Murcia Region. An exploratory factorial analysis used “benefits of inclusion” and “problems of the teachers” as the two dominant factors along with acceptable coefficients. An explained total variance of 35.98% was used to check the validity of the questionnaire. After the respective variance analysis, it was verified that women considered the benefits from activities in the curriculum more important than their own problems. Whereas, the problems presented were taken in account by the teachers who had to teach classes with a water expert present to be included in the school curriculum. Having a Bachelor of Science degree in Physical Education and Sport does not imply a better knowledge of the benefits nor that fewer problems with the activities will occur. The results were argued among other research and a wide range of bibliography.

    Burdett, Garry J; Dewberry, Kirsty; Staff, James

    2016-01-01

    The aim of this study was to investigate the concentrations of airborne asbestos that can be released into classrooms of schools that have amosite-containing asbestos insulation board (AIB) in the ceiling plenum or other spaces, particularly where there is forced recirculation of air as part of a warm air heating system. Air samples were collected in three or more classrooms at each of three schools, two of which were of CLASP (Consortium of Local Authorities Special Programme) system-built design, during periods when the schools were unoccupied. Two conditions were sampled: (i) the start-up and running of the heating systems with no disturbance (the background) and (ii) running of the heating systems during simulated disturbance. The simulated disturbance was designed to exceed the level of disturbance to the AIB that would routinely take place in an occupied classroom. A total of 60 or more direct impacts that vibrated and/or flexed the encapsulated or enclosed AIB materials were applied over the sampling period. The impacts were carried out at the start of the sampling and repeated at hourly intervals but did not break or damage the AIB. The target air volume for background samples was ~3000 l of air using a static sampler sited either below or ~1 m from the heater outlet. This would allow an analytical sensitivity (AS) of 0.0001 fibres per millilitre (f ml(-1)) to be achieved, which is 1000 times lower than the EU and UK workplace control limit of 0.1 f ml(-1). Samples with lower volumes of air were also collected in case of overloading and for the shorter disturbance sampling times used at one site. The sampler filters were analysed by phase contrast microscopy (PCM) to give a rapid determination of the overall concentration of visible fibres (all types) released and/or by analytical transmission electron microscopy (TEM) to determine the concentration of asbestos fibres. Due to the low number of fibres, results were reported in terms of both the calculated

    Background There is little information on the impact of intra-operative systemic chemotherapy on gastric cancer.The aim of this study was to identify prognostic factors in patients with locally advanced gastric cancer and undergoing curative resection,with a focus on evaluating survival benefits and tolerance of intra-operative systemic chemotherapy.Methods We retrospectively analyzed clinicopathological data for 264 consecutive patients who underwent curative resection for gastric cancer at Peking Union Medical College Hospital from January 2002 to January 2007.Survival curves were plotted using the Kaplan-Meier method and compared using log-rank tests.Univariate and multivariate analyses were performed with the Cox proportional hazard model.Results Patients who received intra-operative systemic chemotherapy had higher 5-year overall survival and 5-year disease-free survival rates (P=0.019 and 0.010,respectively) than patients who did not receive intra-operative systemic chemotherapy.In the subgroup analysis,systemic intra-operative chemotherapy benefited the 5-year overall survival and disease-free survival rates for patients with cancer of stage pTNM ⅠB-ⅢB,but not stage pTNM ⅢC.Patients who received intra-operative systemic chemotherapy in combination with post-operative chemotherapy had higher 5-year overall survival and 5-year disease-free survival rates (P=0.046 and 0.021,respectively) than patients who only received postoperative chemotherapy.However,the difference in these rates between patients who received only intra-operative systemic chemotherapy and patients who only received curative surgery was not statistically significant (P=0.150 and 0.170,respectively).Multivariate analyses showed that intra-operative systemic chemotherapy was a favorable prognostic factor for the overall survival and disease-free survival rates (P =0.048 and 0.023,respectively).No grade 4 toxicities related to intra-operative systemic chemotherapy were recorded within the

    2015-10-01

    Full Text Available Performance appraisal is a formal and structured system followed by the organizations for reviewing and assessing the performance of employees. Organizations‘ initiate the performance appraisals process for administrative purposes and for employee development purposes. For administrative purposes, it assists management in selection; retention; and training of personnel‘s, in estimating the number of personnel required, for rewarding and honoring employees, for legal requirements, and for granting hike in employees‘ salary. For employee development purposes, the appraisal process is used to communicate employees‘ strengths & weaknesses, to identify individuals‘ training needs & identify gaps in workers‘ performance, to judge the efficiency of human resource personnel‘s involved with recruitment, selection etc. and also to reduce the grievances of employees. An effective appraisal would always assist organizations in achieving the organizational goals. Nevertheless, an appraisal would also be the cause of negative experience when the managers judge the employees‘ performance in a biased manner. The purpose of this paper is to focus on the purposes of using appraisals in an organization also to emphasize both the benefits and concerns associated with the appraisals. The main purpose of the study is to emphasis comprehensively the various essential requirements of good appraisal system. The good appraisal system is required to overcome the concerns associated with appraisals and to garner the true benefits of appraisals. The present study recommends that, for the successful achievement of organizational objectives, the appraisal system should be appropriate and effective.

  5. Ecosystem Services in Biologically Diversified versus Conventional Farming Systems: Benefits, Externalities, and Trade-Offs

    Directory of Open Access Journals (Sweden)

    Albie Miles

    2012-12-01

    Full Text Available We hypothesize that biological diversification across ecological, spatial, and temporal scales maintains and regenerates the ecosystem services that provide critical inputs--such as maintenance of soil quality, nitrogen fixation, pollination, and pest control--to agriculture. Agrobiodiversity is sustained by diversified farming practices and it also supplies multiple ecosystem services to agriculture, thus reducing environmental externalities and the need for off-farm inputs. We reviewed the literature that compares biologically diversified farming systems with conventional farming systems, and we examined 12 ecosystem services: biodiversity; soil quality; nutrient management; water-holding capacity; control of weeds, diseases, and pests; pollination services; carbon sequestration; energy efficiency and reduction of warming potential; resistance and resilience to climate change; and crop productivity. We found that compared with conventional farming systems, diversified farming systems support substantially greater biodiversity, soil quality, carbon sequestration, and water-holding capacity in surface soils, energy-use efficiency, and resistance and resilience to climate change. Relative to conventional monocultures, diversified farming systems also enhance control of weeds, diseases, and arthropod pests and they increase pollination services; however, available evidence suggests that these practices may often be insufficient to control pests and diseases or provide sufficient pollination. Significantly less public funding has been applied to agroecological research and the improvement of diversified farming systems than to conventional systems. Despite this lack of support, diversified farming systems have only somewhat reduced mean crop productivity relative to conventional farming systems, but they produce far fewer environmental and social harms. We recommend that more research and crop breeding be conducted to improve diversified farming

  7. The Cost and Benefit of Bulk Energy Storage in the Arizona Power Transmission System

    Science.gov (United States)

    Ruggiero, John

    This thesis addresses the issue of making an economic case for energy storage in power systems. Bulk energy storage has often been suggested for large scale electric power systems in order to levelize load; store energy when it is inexpensive and discharge energy when it is expensive; potentially defer transmission and generation expansion; and provide for generation reserve margins. As renewable energy resource penetration increases, the uncertainty and variability of wind and solar may be alleviated by bulk energy storage technologies. The quadratic programming function in MATLAB is used to simulate an economic dispatch that includes energy storage. A program is created that utilizes quadratic programming to analyze various cases using a 2010 summer peak load from the Arizona transmission system, part of the Western Electricity Coordinating Council (WECC). The MATLAB program is used first to test the Arizona test bed with a low level of energy storage to study how the storage power limit effects several optimization out-puts such as the system wide operating costs. Very high levels of energy storage are then added to see how high level energy storage affects peak shaving, load factor, and other system applications. Finally, various constraint relaxations are made to analyze why the applications tested eventually approach a constant value. This research illustrates the use of energy storage which helps minimize the system wide generator operating cost by "shaving" energy off of the peak demand.

  13. Cost Benefit Analysis of the Power Storage System Considering Outage Cost in the Deregulated Power Market

    Science.gov (United States)

    Tsuru, Hirokazu; Fujii, Yasumasa

    In this paper, the authors propose the mathematical model which derives the optimal operation strategies of an on-site power storage system through the use of stochastic dynamic programming technique. The model takes account of the variations and uncertainties of electricity market prices as well as the outage costs of power grid failures. The market price fluctuation is modeled with stochastic differential equation. The stochastic state transitions between normal and failed systems are modeled with exponential density functions. The derived optimal operation indicates that the economic value of the storage system may be increased substantially, if the avoided outage costs are explicitly taken into account. The results of the sensitivity analysis indicate that the most influential parameters are the magnitude of outage cost and the mean time to failure of power grid.

    Cheng, Xi; He, Li; Lu, Hongwei; Chen, Yizhong; Ren, Lixia

    2016-09-01

    A major concern associated with current shale-gas extraction is high consumption of water resources. However, decision-making problems regarding water consumption and shale-gas extraction have not yet been solved through systematic approaches. This study develops a new bilevel optimization problem based on goals at two different levels: minimization of water demands at the lower level and maximization of system benefit at the upper level. The model is used to solve a real-world case across Pennsylvania and West Virginia. Results show that surface water would be the largest contributor to gas production (with over 80.00% from 2015 to 2030) and groundwater occupies for the least proportion (with less than 2.00% from 2015 to 2030) in both districts over the planning span. Comparative analysis between the proposed model and conventional single-level models indicates that the bilevel model could provide coordinated schemes to comprehensively attain the goals from both water resources authorities and energy sectors. Sensitivity analysis shows that the change of water use of per unit gas production (WU) has significant effects upon system benefit, gas production and pollutants (i.e., barium, chloride and bromide) discharge, but not significantly changes water demands.

    2015-01-01

    Progress in diagnosis and treatment of movement disorders after neurological diseases like stroke, cerebral palsy (CP), 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: (1) the interaction between the neural controller and the "plant", comprising the biomechanical properties of the musculaskeletal system 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 (SI), and neuro-mechanical modeling. 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 for biomarkers to increase accuracy of prediction models for functional outcome and effects of intervention.

    CEGAS (Gas Company of Ceara) recently implemented an automated remote monitoring and control system at the Natural Gas Stations located within the city of Fortaleza. The main purposes to implement the project were to install a better operational platform, allowing CEGAS to analyze its operational conditions and to measure customer's consumption in real time. The data communication infra-structure chosen was GPRS/GSM, due to it's low deployment cost and coverage availability. The first phase of the project comprised 50 vehicular natural gas stations. The project was successfully installed, and became the 1{sup st} project at this type to run efficiently over a GPRS infra-structure in Brazil for gas monitoring, with reliable control and data communication. This document intends to present the reasons that lead CEGAS to invest in such a system, the technology deployed and the benefits achieved. (author)

  12. The Rationale/Benefits of Nuclear Thermal Rocket Propulsion for NASA's Lunar Space Transportation System

    Borowski, Stanley K.

    1994-01-01

    The solid core nuclear thermal rocket (NTR) represents the next major evolutionary step in propulsion technology. With its attractive operating characteristics, which include high specific impulse (approximately 850-1000 s) and engine thrust-to-weight (approximately 4-20), the NTR can form the basis for an efficient lunar space transportation system (LTS) capable of supporting both piloted and cargo missions. Studies conducted at the NASA Lewis Research Center indicate that an NTR-based LTS could transport a fully-fueled, cargo-laden, lunar excursion vehicle to the Moon, and return it to low Earth orbit (LEO) after mission completion, for less initial mass in LEO than an aerobraked chemical system of the type studied by NASA during its '90-Day Study.' The all-propulsive NTR-powered LTS would also be 'fully reusable' and would have a 'return payload' mass fraction of approximately 23 percent--twice that of the 'partially reusable' aerobraked chemical system. Two NTR technology options are examined--one derived from the graphite-moderated reactor concept developed by NASA and the AEC under the Rover/NERVA (Nuclear Engine for Rocket Vehicle Application) programs, and a second concept, the Particle Bed Reactor (PBR). The paper also summarizes NASA's lunar outpost scenario, compares relative performance provided by different LTS concepts, and discusses important operational issues (e.g., reusability, engine 'end-of life' disposal, etc.) associated with using this important propulsion technology.

    Municipal economy problems are of a complex nature. Existing requirements for sustainable development make us apply various criteria while solving these problems. These can, for example,include economic, financial, social and environmental criteria. To handle them effectively,multi-criteria analysis should be applied. Decisions about heat production and delivery systems belong to such multidisciplinary problems. They were usually resolved in the past using classical numerical methodology that took into account only the technical and economic merits of the various alternatives.By applying multi-criteria tools instead it is possible to obtain more realistic results and make more effective decisions. The Analytical Hierarchy Process (AHP) seems to be a good alternative to fill the existing gap between decision-making as it is actually practiced and the traditional methods when applied to selecting district heating (DH) systems. This paper presents such an application. Our application is to select the best heat energy source for a DH system for a medium sized city located in Poland. Our results led to an interesting conclusion with regard to the best heat energy source. Our results suggest that intensifying the effort to make widespread the use of more efficient, but financially more costly, energy sources is the best.

    Garrido A.G.

    2005-01-01

    Full Text Available We investigated the systemic and regional hemodynamic effects of early crystalloid infusion in an experimental model of septic shock induced by intravenous inoculation with live Escherichia coli. Anesthetized dogs received an intravenous infusion of 1.2 x 10(10 cfu/kg live E. coli in 30 min. After 30 min of observation, they were randomized to controls (no fluids; N = 7, or fluid resuscitation with lactated Ringer's solution, 16 ml/kg (N = 7 or 32 ml/kg (N = 7 over 30 min and followed for 120 min. Cardiac index, portal blood flow, mean arterial pressure, systemic and regional oxygen-derived variables, blood lactate, and gastric PCO2 were assessed. Rapid and progressive cardiovascular deterioration with reduction in cardiac output, mean arterial pressure and portal blood flow (~50, ~25 and ~70%, respectively was induced by the live bacteria challenge. Systemic and regional territories showed significant increases in oxygen extraction and in lactate levels. Significant increases in venous-arterial (~9.6 mmHg, portal-arterial (~12.1 mmHg and gastric mucosal-arterial (~18.4 mmHg PCO2 gradients were also observed. Early fluid replacement, especially with 32 ml/kg volumes of crystalloids, promoted only partial and transient benefits such as increases of ~76% in cardiac index, of ~50% in portal vein blood flow and decreases in venous-arterial, portal-arterial, gastric mucosal-arterial PCO2 gradients (7.2 ± 1.0, 7.2 ± 1.3 and 9.7 ± 2.5 mmHg, respectively. The fluid infusion promoted only modest and transient benefits, unable to restore the systemic and regional perfusional and metabolic changes in this hypodynamic septic shock model.

    In recent years, the daily clinical volume has increased rapidly to over 3000 patients in the Affiliated Hospital of Guiyang Medical College in southwestern China of Guizhou Province, and the pressure to improve working efficiency and scientific management has increased gradually. Previously, each imaging department and section did not liaise, so the archiving rate of image materials (film) is rather low. Damaged and missing films were a serious problem, adversely affecting the work of teaching, scientific research and clinics to a considerable extent. After establishing and applying a large-scale picture archiving and communication system (PACS), the administration of the hospital in these respects has been vastly improved.

    2008-06-01

    This article discusses the dissemination of a process of youth-led participatory research in urban secondary schools within the Interactive Systems Framework for Dissemination and Implementation (ISF) developed in collaboration with the CDC and its university partners (Wandersman et al. American Journal of Community Psychology, 41(3-4) 2008). The focus here is on the development of the Prevention Support System with respect to general and innovation-specific capacity building. The specific process under study involves youth-led needs assessment and research to inform the planning of prevention programs and policies to address students' health and developmental needs. The article first briefly describes the youth-led research process, its potential benefits, and a case example in two urban secondary schools. It then describes challenges and responses in providing support for the diffusion of this model in 6 secondary schools. The settings are urban public schools with a majority of students of color from diverse ethnic groups: Asian-American, Latino, and African-American. This project constitutes a collaborative partnership with a university school of public health and community-based organizations (CBOs) to build capacity for long-term, sustainable implementation of this innovative process within the local school system. The perspectives of the university-based researcher and the CBO partners on the development and effectiveness of the Prevention Support System are presented.

    Effect of low-level laser irradiation on the central nervous system transplantation is reported. Ernbryonal brain allografts were transplanted into the brain of 20 adult rats and peripheral nerve graft transplanted into the severely injured spinal cord of 16 dogs. The operated wound of 10 rats and 8 dogs were exposed daily for 21 days to lowpower laser irradiation CW HeNe laser (35 mW, 632.8 run, energy density of 30 J/cm2 at each point for rats and 70 J/cm2 at each point for dogs). This study shows that (i) the low-level laser irradiation prevents extensive glial scar formation (a limiting factor in CNS regeneration) between embryonal transplants and host brain; (ii) Dogs made paraplegic by spinal cord injury were able to walk 3-6 months later. Recovery of these dogs was effected by the implantation of a fragment of autologous sciatic nerve at the site of injury and subsequently exposing the dogs to low-level laser irradiation. The effect of laser irradiation on the embryonal nerve cells grown in tissue culture was also observed. We found that low-level laser irradiation induced intensive migration of neurites outward of the aggregates 15-22 The results of the present study and our previous investigations suggest that low-level laser irradiation is a novel tool for treatment of peripheral and central nervous system injuries.

    Cannabis sativa is one of the oldest herbal remedies known to man. Over the past four thousand years, it has been used for the treatment of numerous diseases but due to its psychoactive properties, its current medicinal usage is highly restricted. In this review, we seek to highlight advances made over the last forty years in the understanding of the mechanisms responsible for the effects of cannabis on the human body and how these can potentially be utilized in clinical practice. During this time, the primary active ingredients in cannabis have been isolated, specific cannabinoid receptors have been discovered and at least five endogenous cannabinoid neurotransmitters (endocannabinoids) have been identified. Together, these form the framework of a complex endocannabinoid signalling system that has widespread distribution in the body and plays a role in regulating numerous physiological processes within the body. Cannabinoid ligands are therefore thought to display considerable therapeutic potential and the drive to develop compounds that can be targeted to specific neuronal systems at low enough doses so as to eliminate cognitive side effects remains the 'holy grail' of endocannabinoid research.

    Fisher, D.; Schmid, F.; Spata, A.J.

    1999-07-01

    Kitchen exhaust ventilation systems are recognized as a major energy user within commercial food service facilities and restaurants. Minimizing the design ventilation rate of an appliance/hood system by optimizing hood performance in the laboratory is a viable strategy for reducing the makeup air heating and cooling loads as well as the exhaust and supply fan energy. Cutting back the exhaust flow under conditions of noncooking (appliance idle) can further reduce the energy load associated with a kitchen ventilation system. An optimized, two-speed exhaust system was installed within the scope of an energy-efficient, quick service restaurant (QSR) design and demonstration project. This paper evaluates the energy benefit of this variable-flow strategy as well as the savings associated with reducing the design ventilation rate (compared to an off-the-shelf exhaust hood). The paper describes a new public-domain software tool for estimating heating and cooling loads associated with the makeup air requirements of commercial kitchens. This bin-based software provides ASHRAE engineers with an alternative to hand calculations or more sophisticated hour-by-hour simulation. The dramatic impact that both makeup air set point and geographic location have on the outdoor air load is illustrated. The paper concludes with an industry-wide projection of energy savings associated with optimizing the design and operation of commercial kitchen ventilation (CKV) systems.

    In an effort to better understand the impacts of high penetrations of photovoltaic (PV) generators on distribution systems, Arizona Public Service and its partners completed a multi-year project to develop the tools and knowledge base needed to safely and reliably integrate high penetrations of utility- and residential-scale PV. Building upon the APS Community Power Project-Flagstaff Pilot, this project investigates the impact of PV on a representative feeder in northeast Flagstaff. To quantify and catalog the effects of the estimated 1.3 MW of PV that will be installed on the feeder (both smaller units at homes and large, centrally located systems), high-speed weather and electrical data acquisition systems and digital 'smart' meters were designed and installed to facilitate monitoring and to build and validate comprehensive, high-resolution models of the distribution system. These models are being developed to analyze the impacts of PV on distribution circuit protection systems (including coordination and anti-islanding), predict voltage regulation and phase balance issues, and develop volt/VAr control schemes. This paper continues from a paper presented at the 2014 IEEE PVSC conference that described feeder model evaluation and high penetration advanced scenario analysis, specifically feeder reconfiguration. This paper presents results from Phase 5 of the project. Specifically, the paper discusses tool automation; interconnection assessment methodology and cost benefit analysis.

  6. Science school and culture school: improving the efficiency of high school science teaching in a system of mass science education.

    Science.gov (United States)

    Charlton, Bruce G

    2006-01-01

    Educational expansion in western countries has been achieved mainly by adding years to full-time education; however, this process has probably reduced efficiency. Sooner or later, efficiency must improve, with a greater educational attainment per year. Future societies will probably wish more people to study science throughout high school (aged c. 11-19 years) and the first college degree. 'Science' may be defined as any abstract, systematic and research-based discipline: including mathematics, statistics and the natural sciences, economics, music theory, linguistics, and the conceptual or quantitative social sciences. Since formal teaching is usually necessary to learn science, science education should be regarded as the core function of high schools. One standard way to improve efficiency is the 'division of labour', with increased specialization of function. Modern schools are already specialized: teachers are specialized according to age-group taught, subject matter expertise, and administrative responsibilities. School students are stratified by age and academic aptitude. I propose a further institutional division of school function between science education, and cultural education (including education in arts, sports, ethics, social interaction and good citizenship). Existing schools might split into 'science school' and 'culture school', reflected in distinct buildings and zones, separate administrative structures, and the recruitment of differently-specialized teaching personnel. Science school would be distinguished by its focus on education in disciplines which promote abstract systematic cognition. All students would spend some part of each day (how much would depend on their aptitude and motivation) in the 'science school'; experiencing a traditional-style, didactic, disciplined and rigorous academic education. The remainder of the students' time at school would be spent in the cultural division, which would focus on broader aspects, and aim to generate

    The fuel saving potential and cost effectiveness of numerous operational and technical options proposed for reducing the fuel consumption of the U.S. commercial airline fleet was examined and compared. The impact of the most promising fuel conserving options on fuel consumption, passenger demand, operating costs and airline profits when implemented in the U.S. domestic and international airline fleets was determined. A forecast estimate was made of the potential fuel savings achievable in the U.S. scheduled air transportation system. Specifically, the means for reducing the jet fuel consumption of the U.S. scheduled airlines in domestic and international passenger operations were investigated. A design analysis was made of two turboprop aircraft as possible fuel conserving derivatives of the DC-9-30.

    2016-06-01

    Full Text Available Small and medium enterprises (SMES play an important role in Taiwan’s economy. The reduction of energy costs and carbon dioxide (CO2 emissions are critical to preserving the environment. This paper uses the experimental results from 65 sites, gathered over two years since 2012, to determine how the integration of Internet communication, cloud computing technologies and a cloud energy management service (cloud EMS can reduce energy consumption by cost-effective means. The EMS has three levels: infrastructure as a service (IaaS, platform as a service (PaaS and software as a service (SaaS. Working jointly with ChungHwa Telecom, Taiwan’s leading telecom service provider, data from detection devices, control devices, air-conditioning and lighting systems are all uploaded to a cloud EMS platform, to give a so called intelligent energy management network application service platform (IEN-ASP. Various energy saving management functions are developed using this platform: (1 air conditioning optimization; (2 lighting system optimization; (3 scheduling control; (4 power billing control and (5 occupancy detection and timing control. Using the international performance measurement and verification protocol (IPMVP, the energy used at the test sites, before and after the use of the IEN-ASP, are compared to calculate the energy saved. The experimental results show that there is an average energy saving of 5724 kWh per year, which represents a saving ratio of 5.84%. This translates to a total reduction in CO2 emissions of 9,926,829 kg per year. Using the data collected, a regression model is used to demonstrate the correlation between the power that is consumed, the energy that is saved and the area of the sites. Another interesting result is that, if the experimental sites are maintained by experienced electricians or other personnel and EMS protocols are followed, the energy saving can be as great as 6.59%.

    Despite increasingly large investments, the potential ecological effects of river restoration programs are still small compared to the degree of human alterations to physical and ecological function. Thus, it is rarely possible to “restore” pre-disturbance conditions; rather restoration programs (even large, well-funded ones) will nearly always involve multiple small projects, each of which can make some modest change to selected ecosystem processes and habitats. At present, such projects are typically selected based on their attributes as individual projects (e.g., consistency with programmatic goals of the funders, scientific soundness, and acceptance by local communities), and ease of implementation. Projects are rarely prioritized (at least explicitly) based on how they will cumulatively affect ecosystem function over coming decades. Such projections require an understanding of the form of the restoration response curve, or at least that we assume some plausible relations and estimate cumulative effects based thereon. Drawing on our experience with the CALFED Bay-Delta Ecosystem Restoration Program in California, we consider potential cumulative system-wide benefits of a restoration activity extensively implemented in the region: isolating/filling abandoned floodplain gravel pits captured by rivers to reduce predation of outmigrating juvenile salmon by exotic warmwater species inhabiting the pits. We present a simple spreadsheet model to show how different assumptions about gravel pit bathymetry and predator behavior would affect the cumulative benefits of multiple pit-filling and isolation projects, and how these insights could help managers prioritize which pits to fill.

    2008-02-01

    Full Text Available Abstract Background In Spain, there are substantial variations in the utilization of health resources among regions. Because the need for surgery differs in patients with appropriate surgical indication, introducing a prioritization system might be beneficial. Our objective was to assess geographical variations in the impact of applying a prioritization system in patients on the waiting list for cataract surgery in different regions of Spain by using a discrete-event simulation model. Methods A discrete-event simulation model to evaluate demand and waiting time for cataract surgery was constructed. The model was reproduced and validated in five regions of Spain and was fed administrative data (population census, surgery rates, waiting list information and data from research studies (incidence of cataract. The benefit of introducing a prioritization system was contrasted with the usual first-in, first-out (FIFO discipline. The prioritization system included clinical, functional and social criteria. Priority scores ranged between 0 and 100, with greater values indicating higher priority. The measure of results was the waiting time weighted by the priority score of each patient who had passed through the waiting list. Benefit was calculated as the difference in time weighted by priority score between operating according to waiting time or to priority. Results The mean waiting time for patients undergoing surgery according to the FIFO discipline varied from 1.97 months (95% CI 1.85; 2.09 in the Basque Country to 10.02 months (95% CI 9.91; 10.12 in the Canary Islands. When the prioritization system was applied, the mean waiting time was reduced to a minimum of 0.73 months weighted by priority score (95% CI 0.68; 0.78 in the Basque Country and a maximum of 5.63 months (95% CI 5.57; 5.69 in the Canary Islands. The waiting time weighted by priority score saved by the prioritization system varied from 1.12 months (95% CI 1.07; 1.16 in Andalusia to 2

    Earth System and Space Science emphasizes the dynamic interrelationships between the atmosphere, the geosphere, the hydrosphere, the biosphere and the earth-universe system. There is a strong emphasis on internet-based and technology activities, and laboratory activities. Science skills and processes learned in this course prepare for continued development of scientific inquiry in other science disciplines. A partnership with the Goddard Space Flight Center and collaboration with Anne Arundel County Public Schools provides enhanced richness to the learning activities. Earth and Space scientists from NASA GSFC gave their expertise in the development of ESSS. Their suggestions were the foundation for the development of this curriculum. Earth System and Space Science is a course, which develops student knowledge and understanding of the Earth System and its place in the universe. This course seeks to empower students to understand their dynamic local and global environments and the Earth as part of a complex system. The student will learn the science content necessary to make wise personal and social decisions related to quality of life, and the management of the Earth's finite resources, environments, and hazards. During much of the recent past, scientists have been concerned with examining individual physical, chemical, and biological processes or groups of processes in the atmosphere, hydrosphere, lithosphere, and biosphere. Recently, however, there has been a movement in Earth Science to take a planetary or "system" approach to investigating our planet. Satellite images show planet Earth as one entity without boundaries. There are concerns with environmental issues on regional, global, and even planetary scales. In Earth/Space Systems Science, Earth is viewed as a complex evolving planet that is characterized by continually interacting change over a wide scale of time and space.

    Full Text Available Problem statement: Monitoring Boarding school student movement using the old-fashioned study system is inefficient and brings difficulty to the hostel management to check attendance manually. By using RFID technology, student movement is quick and easy. Approach: The application of RFID Matrix Card system as a boarding school students monitoring system (E-ID were purposed to improve school management system and to monitor interest group movement. The RFID tags enable school management to track the students movements in and out of the hostel. An individual without RFID card will trigger the alarm and this will inform school management about availability of students using an online monitoring system. Results: This system used main component of passive RFID system, database management system and wireless networking. When RFID tag pass through the RFID reader in read range zone, system recorded data from the RFID tag to the database system. Data sent online to the management for the supervision of students. This ease management to monitor availability of boarding school students and access the students personal records. Conclusion: This research study offer important implication for monitoring the boarding school students. Although this project cannot control the punctuation of student but it can ease the workload of school management and save time.

    In spite of being readily available, photographs have played a minor and passive role in science classes. In our study, we present an active way of using photographs in classroom discussions with the use of a classroom response system (CRS) in middle school astronomy classes to teach the concepts of day-night and seasonal change. In this new pedagogical method, students observe objects or phenomena in photographs and use the information to develop understanding of the scientific concepts. They share their ideas in classroom discussion with the assistance of the CRS. Pre- and posttest results showed that the new pedagogy helped students overcome primitive conceptions and enhanced their understanding of the concepts. The observation of the rich details of photographs played three pedagogical roles in classroom discussion: easing students' anxiety about learning a new scientific concept; continuous stimulus of learning; and as evidence or data.

  17. Quantifying habitat benefits of channel reconfigurations on a highly regulated river system, Lower Missouri River, USA

    2017-01-01

    We present a quantitative analysis of habitat availability in a highly regulated lowland river, comparing a restored reach with two reference reaches: an un-restored, channelized reach, and a least-altered reach. We evaluate the effects of channel modifications in terms of distributions of depth and velocity as well as distributions and availability of habitats thought to be supportive of an endangered fish, the pallid sturgeon (Scaphirhynchus albus). It has been hypothesized that hydraulic conditions that support food production and foraging may limit growth and survival of juvenile pallid sturgeon. To evaluate conditions that support these habitats, we constructed two-dimensional hydrodynamic models for the three study reaches, two located in the Lower Missouri River (channelized and restored reaches) and one in the Yellowstone River (least-altered reach). Comparability among the reaches was improved by scaling by bankfull discharge and bankfull channel area. The analysis shows that construction of side-channel chutes and increased floodplain connectivity increase the availability of foraging habitat, resulting in a system that is more similar to the reference reach on the Yellowstone River. The availability of food-producing habitat is low in all reaches at flows less than bankfull, but the two reaches in the Lower Missouri River – channelized and restored – display a threshold-like response as flows overtop channel banks, reflecting the persistent effects of channelization on hydraulics in the main channel. These high lateral gradients result in punctuated ecological events corresponding to flows in excess of bankfull discharge. This threshold effect in the restored reach remains distinct from that of the least-altered reference reach, where hydraulic changes are less abrupt and overbank flows more gradually inundate the adjacent floodplain. The habitat curves observed in the reference reach on the Yellowstone River may not be attainable within the

  18. Beyond Electric Propulsion: Non-Propulsive Benefits of Nuclear Power for the Exploration of the Outer Solar System

    Zubrin, Robert M.

    1994-07-01

    In the past, most studies dealing with the benefits of space nuclear electric power systems for solar system exploration have focused on the potential of nuclear electric propulsion (NEP) to enhance missions by increasing delivered payload, decreasing LEO mass, or reducing trip time. While important, such mission enhancements have failed to go to the heart of the concerns of the scientific community supporting interplanetary exploration. To put the matter succinctly, scientists don't buy delivered payload - they buy data returned. With nuclear power we can increase both the quantity of data returned, by enormously increasing data communication rates, and the quality of data by enabling a host of active sensing techniques otherwise impossible. These non-propulsive mission enhancement capabilities of space nuclear power have been known in principle for many years, but they have not been adequately documented. As a result, support for the development of space nuclear power by the interplanetary exploration community has been much less forceful than it might otherwise be. In this paper we shall present mission designs that take full advantage of the potential mission enhancements offered by space nuclear power systems in the 10 to 100 kWe range, not just for propulsion, but to radically improve, enrich, and expand the science return itself. Missions considered include orbiter missions to each of the outer planets. It will be shown that be using hybrid trajectories combining chemical propulsion with NEP and (in certain cases) gravity assists, that it is possible, using a Titan IV-Centaur launch vehicle, for high-powered spacecraft to be placed in orbit around each of the outer planets with electric propulsion burn times of less than 4 years. Such hybrid trajectories therefore make the outer solar-system available to near-term nuclear electric power systems. Once in orbit, the spacecraft will utilize multi-kilowatt communication systems, similar to those now employed by

    Oral health of long-term care (LTC) residents is often poor. From 30 random German LTC facilities, 242 random residents (Berlin n=75, Northrhine-Westfalia (NRW) n=94, Saxony n=73) (median age: 82 years, female: 78.5%) were interviewed as to their use of dental services, possession of a bonus booklet (BB), and completeness of records. Only 18.6% possessed a BB. Significant regional differences were observed (Berlin=5.3%, NRW=18.1%, Saxony=32.9%) (χ(2) test p<0.01). The number of teeth was higher (Mann-Whitney test p=0.01) and the time since last dental visit shorter (p<0.01) for all residents with a BB. Only 18.6% of people possessing a BB declared not having had a dental appointment within the previous 12 months (LTC residents without BB 51.3%). As a means towards improved quality management in nursing, better oral infection control of residents and increased oral health and general quality of life, the introduction of a regular annual preventive dental screening program including the use of a dental bonus system are suggested.

    Many communities and villages around the world face serious problems with lack of sanitation especially in disposing of the wastewater-black water and grey water from the houses, or wash outs from animal rearing sheds. Across the world diverting wastewater to the surroundings or to the public spaces are not uncommon. This is responsible for contaminating drinking water sources causing health risks and environmental degradation as they become the breeding grounds of mosquitoes and pathogens. Lack of collection and treatment facilities or broken down sewage systems noticed throughout the developing world are associated with this situation. Diverting the wastewater to trees and vegetable gardens was historically a common practice. However the modern world has an array of problems associated with such disposal such as generation of large quantity of wastewater, unavailability of space for onsite disposal or treatment and increase in population. This paper considers the wastewater garden as a means for wastewater treatment and to improve the vegetation and biodiversity of rural areas. This can also be implemented in urban areas in association with parks and open spaces. This also highlights environmental safety in relation to the nutrient, pathogen and heavy metal content of the wastewater. The possibilities of different types of integration and technology that can be adopted for wastewater gardens are also discussed.

    The emergence of social media platforms in the consumer space unlocked new ways of interaction between individuals on the Web. People develop now their social networks and relations based on common interests and activities with the choice to opt-in or opt-out on content of their interest. This kind of platforms have also an important place to fill inside large organizations and enterprises where communication and collaborators interaction are keys for development. Enterprise Social Networking Systems (ESN) add value to an organization by encouraging information sharing, capturing knowledge, enabling action and empowering people. CERN is currently rolling out an ESN which aims to unify and provide a single point of access to the multitude of information sources in the organization. It also implements social features that can be added on top of existing communication channels. While the deployment of this kind of platforms is not without risks we firmly believe that they are of the best interest for our community, opening the opportunity to evaluate a global social network for High Energy Physics (HEP).

Implementation considerations for secondment as a health workforce development strategy are not well documented. The purpose of this article is to present outcomes, best practices, and lessons learned from a President's Emergency Plan for AIDS Relief-funded secondment program in Botswana. Outcomes are documented across four World Health Organization health systems' building blocks. Best practices include documentation of joint stakeholder expectations, collaborative recruitment, and early identification of counterparts. Lessons learned include inadequate ownership, a two-tier employment system, and ill-defined position duration. These findings can inform program and policy development to maximize the benefit of health workforce secondment. Secondment requires substantial investment, and emphasis should be placed on high-level technical positions responsible for building systems, developing health workers, and strengthening government to translate policy into programs.

    2015-01-01

    Radio-frequency identification (RFID) technology is used by hospital supply chains to track medical products and monitor inventories. Hospitals have also begun incorporating RFID technology as part of their transfusion processes. The purpose of this review was to analyze how healthcare organization supply chains can benefit from the utilization of RFID systems in transfusion service departments. The methodology for this study was a literature review following the steps of a systematic review with a total of 52 sources referenced. RFID technology is used to manage and track blood products from the initial donor phlebotomy to final disposition or product transfusion. RFID-enabled transfusion practices have successfully increased provider productivity and product quality through work-time reduction and error reduction. Findings of this research study suggest that RFID has provided improvements in quality of care and efficiency, while initial costs, security, and privacy appear to be the principal barriers to adoption.

  13. Multi-species and multifunctional smallholder tree farming systems in Southeast Asia: timber, NTFPs, plus environmental benefits

    Directory of Open Access Journals (Sweden)

    James M. Roshetko

    2015-12-01

    Full Text Available The rapid increase in human population, and the corresponding worldwide enhancement of social and economical conditions, are exerting a considerable pressure to convert forests to other uses. Moreover, these phenomena raise  the demand for food, fuel, wood fibers and other non-wood products, contributing to a further boost of the production pressure in the surviving forests. Simultaneously, these forests are expected to provide a diverse array of environmental services.Furthermore, smallholder forestry systems are prominent components of ‘trees outside the forest’ in Southeast Asia and they are primarily ‘planted’ systems that rehabilitate or reforest marginal lands, in order to produce tree products and services. As they traditionally are a means of producing goods for home consumption, they have become significant suppliers of products for local, national and international markets.The aim of this paper is to demonstrate that smallholder forestry systems are a viable management system  which is significantly contributing to global environmental goals and local economic objectives. This paper reviews global and Asian trends of human population growth, deforestation, and demand for forest and tree products.The origin, the diversity, the adaptable management and the importance of smallholder tree-based systems are here discussed and significant details are provided on the role of smallholder tree-based systems in the mitigation of deforestation, which could be obtained by expanding regional forest resources; in supplying alternative sources of forest products and environmental benefits; and in making significant contributions to local livelihoods for rural communities.

    2006-09-01

    Schools can potentially benefit from system-wide approaches to the dissemination of health promotion practices. This intervention study undertaken in the Hunter Region of NSW, Australia, used a pre-post design to assess whether a phone and mail intervention dissemination strategy was associated with an increase in the proportion of 218 primary schools undertaking eight health promotion practices. Health promotion practices addressed the prevention of harm associated with five agreed health issues-smoking, nutrition, playground safety, asthma and infectious diseases. The study also assessed acceptability of the dissemination strategy to schools, cost and whether intervention schools' characteristics were associated with uptake of health promotion practices. Compared to baseline a significant improvement in prevalence was observed at both 1 and 2 year follow-up for seven of the eight health promotion practices addressed. The greatest improvement occurred in the first year of the project. There was a greater uptake of the practice of providing information regarding passive smoking in urban schools. The dissemination strategy was found to have a cost per adopted practice of 121 Australian dollars and to be acceptable to the large majority (>90%) of schools. The results suggest that the dissemination strategy may represent a relatively low cost method of enhancing health promotion practices in schools and of monitoring such practices. Further research addressing the methodological issues of this study is needed to confirm these findings.

    The role of outreach activities is sending proper information straight to the audience. We want to add quality with a view to have a much higher dimension. It is education we are aiming at by the means of outreach activities. Be it spoken, written or read for the public. That is why we are trying to promote this kind of collaboration between professional scientists and mass media representatives. First of all, the most important target is the school children and youth people, the day after tomorrow's researchers. Secondly, we do have a very strong motivation for action because of the total lack of astronomy education in the national curricula. The future of the planetary systems education depends on how they understand and perceive the study of celestial bodies. Knowing the Solar System is important and decisive for understanding and protecting the Earth. We do have within the Solar System some kind of 'celestial teachers' who are lecturing for free even if we are considering environmentally issues. Let us think of Venus and we might have one possible scenario for our native planet if proper action is not taken. The 'beautiful planet' traps solar radiation in its atmosphere in an exaggerated version of our own Greenhouse Effect. Moreover, various impacts on celestial bodies may give us another dimension of the future. The European space missions could be the principal core of fulfilling all of these. That is the reason for better knowing the Solar System. Last but not in the least, the paper comes naturally as part of our efforts to celebrate IHY, 50 years of space research, as well as preparing IYA 2009.

    Tian, Lili; Zhao, Jie; Huebner, E Scott

    2015-12-01

    This 6-week longitudinal study aimed to examine a moderated mediation model that may explain the link between school-related social support (i.e., teacher support and classmate support) and optimal subjective well-being in school among adolescents (n = 1316). Analyses confirmed the hypothesized model that scholastic competence partially mediated the relations between school-related social support and subjective well-being in school, and social acceptance moderated the mediation process in the school-related social support--> subjective well-being in school path and in the scholastic competence--> subjective well-being in school path. The findings suggested that both social contextual factors (e.g., school-related social support) and self-system factors (e.g., scholastic competence and social acceptance) are crucial for adolescents' optimal subjective well-being in school. Limitations and practical applications of the study were discussed.

    This cost-benefit analysis compared the costs of implementing the New Beginnings Program (NBP), a preventive intervention for divorced families to monetary benefits saved in mental healthcare service use and criminal justice system costs. NBP was delivered when the offspring were 9-12 years old. Benefits were assessed 15 years later when the offspring were young adults (ages 24-27). This study estimated the costs of delivering two versions of NBP, a single-component parenting-after-divorce program (Mother Program, MP) and a two-component parenting-after-divorce and child-coping program (Mother-Plus-Child Program, MPCP), to costs of a literature control (LC). Long-term monetary benefits were determined from actual expenditures from past-year mental healthcare service use for mothers and their young adult (YA) offspring and criminal justice system involvement for YAs. Data were gathered from 202 YAs and 194 mothers (75.4 % of families randomly assigned to condition). The benefits, as assessed in the 15th year after program completion, were $1630/family (discounted benefits $1077/family). These 1-year benefits, based on conservative assumptions, more than paid for the cost of MP and covered the majority of the cost of MPCP. Because the effects of MP versus MPCP on mental health and substance use problems have not been significantly different at short-term or long-term follow-up assessments, program managers would likely choose the lower-cost option. Given that this evaluation only calculated economic benefit at year 15 and not the previous 14 (nor future years), these findings suggest that, from a societal perspective, NBP more than pays for itself in future benefits.

    Advanced satellite sensors are tasked with improving global-scale measurements of the Earth's atmosphere, clouds, and surface to enable enhancements in weather prediction, climate monitoring, and environmental change detection. Validation of the entire measurement system is crucial to achieving this goal and thus maximizing research and operational utility of resultant data. Field campaigns employing satellite under-flights with well-calibrated FTS sensors aboard high-altitude aircraft are an essential part of this validation task. The National Polar-orbiting Operational Environmental Satellite System (NPOESS) Airborne Sounder Testbed-Interferometer (NAST-I) has been a fundamental contributor in this area by providing coincident high spectral/spatial resolution observations of infrared spectral radiances along with independently-retrieved geophysical products for comparison with like products from satellite sensors being validated. This paper focuses on some of the challenges associated with validating advanced atmospheric sounders and the benefits obtained from employing airborne interferometers such as the NAST-I. Select results from underflights of the Aqua Atmospheric InfraRed Sounder (AIRS) and the Infrared Atmospheric Sounding Interferometer (IASI) obtained during recent field campaigns will be presented.

    stitching of F-TPS gores. Additionally, new approaches and hardware will be required for handling and ground testing of both individual tori and the fully assembled HIADs. There are also noteworthy benefits of scaling up the HIAD aeroshell to 15m-class system. Two complications in working with handmade textiles structures are the non-linearity of the materials and the role of human accuracy during fabrication. Larger, more capable, HIAD structures should see much larger operational loads, potentially bringing the structural response of the materials out of the non-linear regime and into the preferred linear response range. Also, making the reasonable assumption that the magnitude of fabrication accuracy remains constant as the structures grow, the relative effect of fabrication errors should decrease as a percentage of the textile component size. Combined, these two effects improve the predictive capability and the uniformity of the structural response for a 12-15m class HIAD. In this paper, the challenges and associated mitigation plans related to scaling up the HIAD stacked-torus aeroshell to a 15m class system will be discussed. In addition, the benefits of enlarging the structure will be further explored.

    The first edition of this introduction to the methods of energy planning and energy systems analysis by means of SESAM model was prepared for discussion at the International Workshop on Local, Regional and National Energy Planning, held at Slettestrand, Denmark, April 6-9- 1997. The project also comprised the development of new and improved program facilities which support the user in the preparation and management of SESAM databases as well as a new method for the specification of scenarios, based on the concept of macro-variables. These facilities are described in this report. Furthermore, additional facilities for the export of data from the SESAM model to MS EXCEL for the preparation of graphical representations are provided as a result of the project. New efficient tools have been added to the SESAM model. In addition to the new database management tools provided, the new systems analysis facilities, based upon the concept of macro-variables, have made analytical method more readily comprehendible and easy to use. Another important result of this project is the establishment of a European network of energy planners engaged in local and regional energy planning project. (EG)

    2016-03-01

    Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare aggressive myeloid neoplasm which shows a high rate of central nervous system (CNS) recurrence and overall survival (OS) of <1 year. Despite this, screening for CNS involvement is not routinely performed at diagnosis and intrathecal (IT) prophylaxis is not regularly administered in BPDCN. Here, we prospectively evaluated 13 consecutive BPDCN patients for the presence of CNS involvement by flow cytometry. Despite none of the patients presented with neurological symptoms, occult CNS involvement was detected in 6/10 cases evaluated at diagnosis and 3/3 studied at relapse/progression. BPDCN patients evaluated at diagnosis received IT treatment -either CNS prophylaxis (n = 4) or active therapy (n = 6)- and all but one remain alive (median follow-up of 20 months). In contrast, all three patients assessed at relapse/progression died. The potential benefit of IT treatment administered early at diagnosis on OS and CNS recurrence-free survival of BPDCN was further confirmed in a retrospective cohort of another 23 BPDCN patients. Our results show that BPDCN patients studied at diagnosis frequently display occult CNS involvement; moreover, they also indicate that treatment of occult CNS disease might lead to a dramatically improved outcome of BPDCN.

    2016-01-01

    Background and aims: The indication for endoscopy to investigate anemia of causes other than iron deficiency is not clear. Increasing numbers of endoscopic procedures for anemia raises concerns about costs to the health system, waiting times, and patient safety. The primary aim of this study was to determine the diagnostic yield of endoscopy in patients referred to undergo investigation for anemia. Secondary aims were to identify additional factors enabling the risk stratification of those likely to benefit from endoscopic investigation, and to undertake a cost analysis of performing endoscopy in this group of patients. Methods: We performed a retrospective review of endoscopy referrals for the investigation of anemia over a 12-month period at a single center. The patients were divided into three groups: those who had true iron deficiency anemia (IDA), tissue iron deficiency without anemia (TIDWA), or anemia of other cause (AOC). Outcome measures included finding a lesion responsible for the anemia and a significant change of management as a result of endoscopy. A costing analysis was performed with an activity-based costing method. Results: We identified 283 patients who underwent endoscopy to investigate anemia. A likely cause of anemia was found in 31 of 150 patients with IDA (21 %) and 0 patients in the other categories (P < 0.001). A change of management was observed in 35 patients with IDA (23 %), 1 of 14 patients with TIDWA (7.14 %), and 8 of 119 patients with AOC (6.7 %) (P < 0.001). The cost of a single colonoscopy or gastroscopy was approximated to be $ 2209. Conclusions: Endoscopic investigation for non-IDA comes at a significant cost to our institution, equating to a minimum of $ 293 797 per annum in extra costs, and does not result in a change of management in the majority of patients. No additional factors could be established to identify patients who might be more likely to benefit from endoscopic investigation. The endoscopic

    The NASA Solar System Exploration Research Virtual Institute (SSERVI) is a virtual institute focused on research at the intersection of science and explora-tion, training the next generation of lunar scientists, and community development. The institute is a hub for opportunities that engage the larger scientific and exploration communities in order to form new interdis-ciplinary, research-focused collaborations. Its relative-ly large domestic teams work together along with in-ternational partners in both traditional and virtual set-tings to bring disparate approaches together for mutual benefit. This talk will describe the research efforts of the nine domestic teams that constitute the U.S. com-plement of the Institute and how it is engaging the in-ternational science and exploration communities through workshops, conferences, online seminars and classes, student exchange programs and internships. The Institute is centered on the scientific aspects of exploration as they pertain to the Moon, Near Earth Asteroids (NEAs) and the moons of Mars. It focuses on interdisciplinary, exploration-related science cen-tered around all airless bodies targeted as potential human destinations. Areas of study reported here will represent the broad spectrum of lunar, NEA, and Mar-tian moon sciences encompassing investigations of the surface, interior, exosphere, and near-space environ-ments as well as science uniquely enabled from these bodies. The technical focus ranges from investigations of plasma physics, geology/geochemistry, technology integration, solar system origins/evolution, regolith geotechnical properties, analogues, volatiles, ISRU and exploration potential of the target bodies. SSERVI enhances the widening knowledgebase of planetary research by acting as a bridge between several differ-ent groups and bringing together researchers from the scientific and exploration communities, multiple disci-plines across the full range of planetary sciences, and domestic and

    Full Text Available This paper describes the theoretical and conceptual framework and the research and practice model of Think&EatGreen@School, a community-based action research project aiming to foster food citizenship in the City of Vancouver and to develop a model of sustainable institutional food systems in public schools. The authors argue that educational and policy interventions at the school and school board level can drive the goals of food system sustainability, food security, and food sovereignty. The complex relationship between food systems, climate change and environmental degradation require that international initiatives promoting sustainability be vigorously complemented by local multi-stakeholder efforts to preserve or restore the capacity to produce food in a durable manner. As a step towards making the City of Vancouver green, we are currently involved in attempts to transform the food system of the local schools by mobilizing the energy of a transdisciplinary research team of twelve university researchers, over 300 undergraduate and graduate students, and twenty community-based researchers and organizations working on food, public health, environmental and sustainability education.

    Eyer, James M. (Distributed Utility Associates, Inc., Livermore, CA); Corey, Garth P. (KTech Corporation, Albuquerque, NM)

    2010-02-01

    This guide describes a high-level, technology-neutral framework for assessing potential benefits from and economic market potential for energy storage used for electric-utility-related applications. The overarching theme addressed is the concept of combining applications/benefits into attractive value propositions that include use of energy storage, possibly including distributed and/or modular systems. Other topics addressed include: high-level estimates of application-specific lifecycle benefit (10 years) in $/kW and maximum market potential (10 years) in MW. Combined, these criteria indicate the economic potential (in $Millions) for a given energy storage application/benefit. The benefits and value propositions characterized provide an important indication of storage system cost targets for system and subsystem developers, vendors, and prospective users. Maximum market potential estimates provide developers, vendors, and energy policymakers with an indication of the upper bound of the potential demand for storage. The combination of the value of an individual benefit (in $/kW) and the corresponding maximum market potential estimate (in MW) indicates the possible impact that storage could have on the U.S. economy. The intended audience for this document includes persons or organizations needing a framework for making first-cut or high-level estimates of benefits for a specific storage project and/or those seeking a high-level estimate of viable price points and/or maximum market potential for their products. Thus, the intended audience includes: electric utility planners, electricity end users, non-utility electric energy and electric services providers, electric utility regulators and policymakers, intermittent renewables advocates and developers, Smart Grid advocates and developers, storage technology and project developers, and energy storage advocates.

    Cross-border welfare rights for citizens of European Union member states are intensely contested, yet there is limited research into voter opposition to such rights, sometimes denoted ‘welfare chauvinism’. We highlight an overlooked aspect in scholarly work: the role of stereotypes about...... beneficiaries of cross-border welfare. We present results from an original large-scale survey experiment (N=2525) among Swedish voters, randomizing exposure to cues about recipients' country of origin and family size. Consistent with a model emphasizing the role of stereotypes, respondents react to cues about...... recipient identity. These effects are strongest among respondents high in ethnic prejudice and economic conservatism. The findings imply that stereotypes about who benefits from cross-border welfare rights condition public support for those rights....

  1. S3: School Zone Safety System Based on Wireless Sensor Network

    Directory of Open Access Journals (Sweden)

    Poh Kit Chong

    2009-07-01

    Full Text Available School zones are areas near schools that have lower speed limits and where illegally parked vehicles pose a threat to school children by obstructing them from the view of drivers. However, these laws are regularly flouted. Thus, we propose a novel wireless sensor network application called School zone Safety System (S3 to help regulate the speed limit and to prevent illegal parking in school zones. S3 detects illegally parked vehicles, and warns the driver and records the license plate number. To reduce the traveling speed of vehicles in a school zone, S3 measures the speed of vehicles and displays the speed to the driver via an LED display, and also captures the image of the speeding vehicle with a speed camera. We developed a state machine based vehicle detection algorithm for S3. From extensive experiments in our testbeds and data from a real school zone, it is shown that the system can detect all kinds of vehicles, and has an accuracy of over 95% for speed measurement. We modeled the battery life time of a sensor node and validated the model with a downscaled measurement; we estimate the battery life time to be over 2 years. We have deployed S3 in 15 school zones in 2007, and we have demonstrated the robustness of S3 by operating them for over 1 year.

    structural webbing, initial inflation of tori, and stitching of F-TPS gores. Additionally, new approaches and hardware will be required for handling and ground testing of both individual tori and the fully assembled HIADs. There are also noteworthy benefits of scaling up the HIAD aeroshell to a 15m-class system. Two complications in working with handmade textile structures are the non-linearity of the material components and the role of human accuracy during fabrication. Larger, more capable, HIAD structures should see much larger operational loads, potentially bringing the structural response of the material components out of the non-linear regime and into the preferred linear response range. Also, making the reasonable assumption that the magnitude of fabrication accuracy remains constant as the structures grow, the relative effect of fabrication errors should decrease as a percentage of the textile component size. Combined, these two effects improve the predictive capability and the uniformity of the structural response for a 12-15-meter HIAD. In this presentation, a handful of the challenges and associated mitigation plans will be discussed, as well as an update on current manufacturing and testing that addressing these challenges.

    2016-02-01

    Full Text Available Health promoting schools (HPS is recognized globally as a multifaceted approach that can support health behaviours. There is increasing clarity around factors that influence HPS at a school level but limited synthesized knowledge on the broader system-level elements that may impact local implementation barriers and support uptake of a HPS approach. This study comprised a scoping review to identify, summarise and disseminate the range of research to support the uptake of a HPS approach across school systems. Two reviewers screened and extracted data according to inclusion/exclusion criteria. Relevant studies were identified using a multi-phased approach including searching electronic bibliographic databases of peer reviewed literature, hand-searching reference lists and article recommendations from experts. In total, 41 articles met the inclusion criteria for the review, representing studies across nine international school systems. Overall, studies described policies that provided high-level direction and resources within school jurisdictions to support implementation of a HPS approach. Various multifaceted organizational and professional interventions were identified, including strategies to enable and restructure school environments through education, training, modelling and incentives. A systematic realist review of the literature may be warranted to identify the types of intervention that work best for whom, in what circumstance to create healthier schools and students.

  14. Benefits from flywheel energy storage for area regulation in California - demonstration results : a study for the DOE Energy Storage Systems program.

    Energy Technology Data Exchange (ETDEWEB)

    Eyer, James M. (Distributed Utility Associates, Livermore, CA)

    2009-10-01

    This report documents a high-level analysis of the benefit and cost for flywheel energy storage used to provide area regulation for the electricity supply and transmission system in California. Area regulation is an 'ancillary service' needed for a reliable and stable regional electricity grid. The analysis was based on results from a demonstration, in California, of flywheel energy storage developed by Beacon Power Corporation (the system's manufacturer). Demonstrated was flywheel storage systems ability to provide 'rapid-response' regulation. Flywheel storage output can be varied much more rapidly than the output from conventional regulation sources, making flywheels more attractive than conventional regulation resources. The performance of the flywheel storage system demonstrated was generally consistent with requirements for a possible new class of regulation resources - 'rapid-response' energy-storage-based regulation - in California. In short, it was demonstrated that Beacon Power Corporation's flywheel system follows a rapidly changing control signal (the ACE, which changes every four seconds). Based on the results and on expected plant cost and performance, the Beacon Power flywheel storage system has a good chance of being a financially viable regulation resource. Results indicate a benefit/cost ratio of 1.5 to 1.8 using what may be somewhat conservative assumptions. A benefit/cost ratio of one indicates that, based on the financial assumptions used, the investment's financial returns just meet the investors target.

    Quantitative results from Environmental Management Systems (EMS) at primary schools have rarely been examined in literature. This paper presents the monitoring results of environmental care in 39 primary schools in Northern South Africa. During 2 years, after the EMS was implemented in the curriculum and in the school's management, the progress of environmental performances of the participating schools has been measured, by means of detailed questionnaires, related to four environmental aspects: water, waste, energy and greening. At the beginning of the project, 50% of the schools performed well on water-related environmental actions. Two years later it was 76%. For waste-related activities the improvement was even stronger: from 50% to 100%. The environmental performances of the schools improved also for greening-related actions, from 50% at the start of the project to 64% two years later. Only energy-related activities did not improve significantly with only 24% of all schools performing well at the end of the survey period. In general, the introduction of an EMS succeeded in an improvement of the overall environmental performances of the schools, but cost-intensive activities were less successful than others.

  16. New Forms of Management and Governance in the School System in England and Wales

    2011-04-01

    Full Text Available The imposition of the neo-liberal agenda in the school system is a difficult entity. It requires new systems of control. These are particularly important in relation to the development of a more decentralised system of schools. This article examines how to exercise control over a more decentralised education system, the requirements of new forms of management and regulation, which this article itemises into 5 categories. All of these are accompanied by a systematic ideological offensive to persuade teachers, parents, students, voters that these reforms are desirable and that there is no credible alternative. This article examines 3 of these categories, the management and leadership of schools, transformational leadership and distributed leadership and new forms of coordination in local systems. Also analysed are education governance networks, issues surrounding the new forms of educational governance and management, the resistance to change factors and an alalysis of viable alternatives.

    Full Text Available This paper describes internal quality system petformance at three Indonesian nursing schools and examines the match of the existing accreditation programmes with the developing internal quality system. A cross sectional study is used with self-administered questionnaires and applied to selected nursing schools. The questionnaire was designed according tocategories of framework of total quality management model. Interview and discussion with respondents including snowball sampling to other teachers and staffs were petformed to clarify and validate data and to enriched the information The activities measured were the enabling and the results factors. The enablers were including Leaderships, strategy, resources, human resources, educational management, teaching teaming process, research and development and also evaluation mechanism, while the results were covering students and personnel satisfaction and partnership.Results shows that some enabling factors were not included in the accreditation, while several indicators in the sub component of accreditation did not explicitly reflect internal quality system petformance. The school stratum as the outcome result of a quality measure is analogue to customer satisfaction, which would depend on direct influence of internal factors such as quality of schools leadership, strategy and educational management. Since the total accreditation score affects school strata and public recognition, it is necessary to use more objectives and relevant indicators by incorporating the internal and external factors as a measure of school quality petformances. Key words: accreditation, education, quality system evaluation, nursing

    2008-09-01

    Full Text Available Abstract This review will discuss some issues related to the risk/benefit profile of the use of dietary antioxidants. Thus, recent progress regarding the potential benefit of dietary antioxidants in the treatment of chronic diseases with a special focus on immune system and neurodegenerative disorders will be discussed here. It is well established that reactive oxygen species (ROS play an important role in the etiology of numerous diseases, such as atherosclerosis, diabetes and cancer. Among the physiological defense system of the cell, the relevance of antioxidant molecules, such as glutathione and vitamins is quite well established. Recently, the interest of researchers has, for example, been conveyed on antioxidant enzyme systems, such as the heme oxygenase/biliverdin reductase system, which appears modulated by dietary antioxidant molecules, including polyphenols and beta-carotene. These systems possibly counteract oxidative damage very efficiently and finally modulate the activity of oxidative phenomena occurring, for instance, during pathophysiological processes. Although evidence shows that antioxidant treatment results in cytoprotection, the potential clinical benefit deriving from both nutritional and supplemental antioxidants is still under wide debate. In this line, the inappropriate assumption of some lipophylic vitamins has been associated with increased incidence of cancer rather than with beneficial effects.

    1. Evolutionary conflicts of interest underlie mutualisms, including plant/pollinator interactions. This is particularly evident in 'nursery pollination', in which the pollinators lay eggs inside the flowers and the offspring of the pollinator consume the developing seeds. Low benefit (pollination service) to cost (seed predation) ratios could destabilize such associations towards parasitism. 2. Although in most of the well-known cases pollen transfer is associated with oviposition, in some ...
