    2008-10-15

    In the United Kingdom several educational buildings were built in the last decades with a strong environmental ethos, real icons of a new generation of low-energy sustainable buildings. For some of the buildings the performance was assessed. Also in the Netherlands several new concepts were developed for sustainable schools during the last years. This is an interesting topic as many of those schools had problems concerning energy efficiency, indoor air quality and thermal comfort. In the case of sustainable schools much effort was put into the design process of the schools to try to find better solutions to face the problems of the traditional designs. This resulted in different solution concepts, which raises the question which are better school concepts. From the literature three evaluations from the UK and one overview of five sustainable educational buildings from the Netherlands are given, which show that sustainable educational buildings are not always without flaws. In the paper two of the first Dutch sustainable elementary schools are compared with nine more traditional schools of the Netherlands to conclude whether the sustainable schools perform better than traditional schools.

    Full Text Available Sustainable construction is important for the continuation of life in a healthy world for futuregenerations; many issues affecting the quality of life such as effective use of resources, take advantage ofrenewable energy, the choice of recyclable materials that do not harm the environment and waterconservation are considered in the context of sustainable design. Implementations carried out in thisframework are regarded as valuable due to providing the consciousness of sustainability to the society.Creating the awareness of sustainability is given a great importance by educators; thus, “education forsustainability” are included from the preschool program so that children can learn the gainings of suchperspective in their early ages. In support of this concept, it is believed that education structures should bea laboratory where children can practice theoretical knowledge learned at school. In that respect, studiesneed to be considered in the context of sustainable construction are studied in this research. In the study,after a description of the importance of sustainable design as a learning mean, significant subjects such asusing natural light, heating, cooling and air-conditioning methods, wind energy, water protection andmaterial selection are analyzed in terms of designing sustainable schools. It is criticized worldwide thatstructures ground on sustainable design principles are relatively few in numbers. Despite, there is anincreasing interest to the subject in Turkey later years; a lot more steps are required in terms ofimplementation and research of the issue. Thus, the purpose of the study is to provide a supplementaryreference for school designs.

    Fagen, Michael C; Flay, Brian R

    2009-02-01

    Sustaining effective school-based prevention programs is critical to improving youth and population-based health. This article reports on results from the Aban Aya Sustainability Project, an effort to sustain a school-based prevention program that was tested via a randomized trial and targeted violence, drug use, and risky sex-related behaviors among a cohort of 5th-grade African American children followed through 10th grade. Sustainability project health educators trained parent educators to deliver the Aban Aya prevention curriculum in five schools, and project researchers studied the resultant curricular implementation and relations between the research and school-based teams. Study results showed uneven implementation across the five schools that we largely attributed to parent educator preparation and parent educator-health educator relations. These and related results are discussed to answer the study's primary research question: How viable was the sustainability project's parent-centered approach to sustaining a school-based prevention program?

    Luiza O. de Sousa

    2017-05-01

    Full Text Available This research explores sustainable environmental management indicators in South African primary schools. Of key interest is the comparison of a township, farm and urban primary school that identify indicators that promote education for sustainable development in schools that implement an environmental management system. Data are drawn from one-on-one interviews, focus group interviews, observations and document analysis from 35 participants in three schools. A comparison of the three schools was done by content and thematic analysis of a within-case analysis. Data from the township school revealed that socioeconomic factors and organisational structure promote education for sustainable development. The farm school data revealed that health promotion can be managed within an environmental management system within a hierarchical school structure. The urban school data revealed that an economic inducement brings a school to realise that it can reduce its carbon footprint, gain financially and utilize its resources with innovation. A case is made that the four pillars of sustainable development (environment, society, economy, and governance endorse education for sustainable development. Furthermore, the objectives of environmental education ought to remain nested in an environmental management system to ensure that the global goal of quality education is achieved.

    2017-02-01

    Sustainability of health promotion programs is essential to maintain their positive effects. However, few studies have examined the extent of program sustainability and the factors influencing it. We examined these issues through the Good Behaviour Game (GBG), a classroom-based program in primary schools with beneficial behavioural and health-related effects that was implemented in 2008. GBG coordinators of 17 participating schools were invited in the study 2 years after the initial program implementation. Sustainability was measured using a 20-item checklist comprised of four dimensions of routinization including: memory, adaptation, values and rules. A semi-structured interview was then completed with 16 of the GBG coordinators to discuss the checklist scores and to probe in more depth the current level of sustainability. Based on the checklist scores, sustainability of the GBG was considered ‘high’ in five schools, ‘medium’ in another five and ‘weak’ in six. Factors influencing sustainability identified by GBG coordinators were organizational strength, strong leadership, program championship and the perceived modifiability and effectiveness of the GBG. Also, different factors were related to different dimensions of routinization. The combination of a sustainability checklist and an interview about influential factors may help to further clarify the sustainability construct and reveal which implementation sites, routinization dimensions and influential factors should be explored to further facilitate the sustaining of programs with proven effectiveness.

    To describe the development and application of the School Food Environment Assessment Tools and a novel scoring system to assess the integration of healthy and environmentally sustainable food initiatives in elementary and secondary schools. The cross-sectional study included direct observations of physical food environments and interviews with key school personnel regarding food-related programmes and policies. A five-point scoring system was then developed to assess actions across six domains: (i) food gardens; (ii) composting systems; (iii) food preparation activities; (iv) food-related teaching and learning activities; and availability of (v) healthy food; and (vi) environmentally sustainable food. Vancouver, Canada. A purposive sample of public schools (n 33) from all six sectors of the Vancouver Board of Education. Schools scored highest in the areas of food garden and compost system development and use. Regular integration of food-related teaching and learning activities and hands-on food preparation experiences were also commonly reported. Most schools demonstrated rudimentary efforts to make healthy and environmentally sustainable food choices available, but in general scored lowest on these two domains. Moreover, no schools reported widespread initiatives fully supporting availability or integration of healthy or environmentally sustainable foods across campus. More work is needed in all areas to fully integrate programmes and policies that support healthy, environmentally sustainable food systems in Vancouver schools. The assessment tools and proposed indicators offer a practical approach for researchers, policy makers and school stakeholders to assess school food system environments, identify priority areas for intervention and track relevant changes over time.

  3. School development and education for sustainable development

    Energy Technology Data Exchange (ETDEWEB)

    Centrone, Liza [Univ. of Bressanone (Italy)

    2008-07-01

    OECD (2003) has developed a set of six scenarios for schooling in the future up to 2020. They have been clustered into three main categories: Scenarios 1a and 1b ''Attempting to Maintain the Status Quo'', 2a and 2b ''Re-schooling'', and 3a and 3b ''De-schooling''. The scenarios describe in a somewhat ''pure form'' how schooling in general might take place in about fifteen years. In reality, of course, one would expect complex mixes to emerge between these different possible futures, rather than one or the other. By sharpening the alternatives, however, they provide an opportunity to think about what we want and do not want, and how probable the more or less desired choices are in terms of on-going trends and policies.

  5. Sustainability Education in Indian Business Schools: A Status Review

    Directory of Open Access Journals (Sweden)

    PD JOSE

    Full Text Available Sustainability issues, given their potential scale of impact and urgency, have captured the imagination of both corporations and academic institutions everywhere. This paper examines how such problems and their potential solutions have been incorporated into higher education, particularly business school education in India. With over 3,600 business schools in the public and private sector, business education in India has proliferated. However, students by and large still remain unexposed to sustainability and disaster management concepts in their curriculum. The underlying factors for this include, lack of institutional capacity, issues related to faculty motivation and incentives, lack of recruiter interest and limited availability to high quality resource material. Further, while several schools in India focus on sectors relevant to sustainability, inter-organizational linkages have not developed and business school generally operate independently. This paper examines the way forward to deeply integrate sustainability principles into the core curriculum of business schools. Measures suggested include creating communities of practice among academia and industry, building a resource base of teaching materials for easy access by faculty, and several measures to strengthen institutional capacity.

  6. Sustainability of outdoor school ground smoking bans at secondary schools: a mixed-method study.

    Rozema, A D; Mathijssen, J J P; Jansen, M W J; van Oers, J A M

    2018-02-01

    Although increasing numbers of countries are implementing outdoor school ground smoking bans at secondary schools, less attention is paid to the post-implementation period even though sustainability of a policy is essential for long-term effectiveness. Therefore, this study assesses the level of sustainability and examines perceived barriers/facilitators related to the sustainability of an outdoor school ground smoking ban at secondary schools. A mixed-method design was used with a sequential explanatory approach. In phase I, 438 online surveys were conducted and in phase II, 15 semi-structured interviews were obtained from directors of relevant schools. ANOVA (phase I) and a thematic approach (phase II) were used to analyze data. Level of sustainability of an outdoor school ground smoking ban was high at the 48% Dutch schools with an outdoor smoking ban. Furthermore, school size was significantly associated with sustainability. The perceived barriers/facilitators fell into three categories: (i) smoking ban implementation factors (side-effects, enforcement, communication, guidelines and collaboration), (ii) school factors (physical environment, school culture, education type and school policy) and (iii) community environment factors (legislation and social environment). Internationally, the spread of outdoor school ground smoking bans could be further promoted. Once implemented, the ban has become 'normal' practice and investments tend to endure. Moreover, involvement of all staff is important for sustainability as they function as role models, have an interrelationship with students, and share responsibility for enforcement. These findings are promising for the sustainability of future tobacco control initiatives to further protect against the morbidity/mortality associated with smoking.

    Full Text Available Recent surveys on the condition of the Italian school building stock provide information on its relevant seismic behavior and fire safety levels, however no information is made available on its thermo-hygrometric conditions and energy behaviour, despite the fact that the former has a considerable impact on the use and physical conditions of indoor environments and the latter plays a fundamental role in limiting the buildings operating costs, as literature abundantly shows. This paper reports the results of a study carried out on a sample of Italian school buildings, substantiating their high levels of energy consumption, and describes the application of a specific method of analysis used for identifying the main causes of these, therefore allowing to propose some possible strategies for retrofitting, aimed to improving the building energy efficiency and environmental quality, by way of simulations and validation of their relevant effects and benefits.

    The United States is facing a surge in the number of school-based health centers (SBHCs) owing to their success in delivering positive health outcomes and increasing access to care. To preserve this success, experts have developed frameworks for creating sustainable SBHCs; however, little research has affirmed or added to these models. This research seeks to analyze elements of sustainability in a case study of three SBHCs in San Diego, California, with the purpose of creating a research-based framework of SBHC sustainability to supplement expertly derived models. Using a mixed methods study design, data were collected from interviews with SBHC stakeholders, observations in SBHCs, and SBHC budgets. A grounded theory qualitative analysis and a quantitative budget analysis were completed to develop a theoretical framework for the sustainability of SBHCs. Forty-one interviews were conducted, 6 hours of observations were completed, and 3 years of SBHC budgets were analyzed to identify care coordination, community buy-in, community awareness, and SBHC partner cooperation as key themes of sustainability promoting patient retention for sustainable billing and reimbursement levels. These findings highlight the unique ways in which SBHCs gain community buy-in and awareness by becoming trusted sources of comprehensive and coordinated care within communities and among vulnerable populations. Findings also support ideas from expert models of SBHC sustainability calling for well-defined and executed community partnerships and quality coordinated care in the procurement of sustainable SBHC funding.

  15. The ethical Dilemma of lifestyle change: designing for sustainable schools and sustainable citizenship

    Directory of Open Access Journals (Sweden)

    Andrea Wheeler

    2009-06-01

    Full Text Available This paper explores how participation and sustainability are being addressed by architects within the Building Schools for the Future (BSF programme in the UK. The intentions promoted by the programme are certainly ambitious, but the ways to fulfil these aims are ill-explored. Simply focusing on providing innovative learning technologies, or indeed teaching young people about physical sustainability features in buildings, will not necessarily teach them the skills they will need to respond to the environmental and social challenges of a rapidly changing world. However, anticipating those skills is one of the most problematic issues of the programme. The involvement of young people in the design of schools is used to suggest empowerment, place-making and to promote social cohesion but this is set against government design literature which advocates for exemplars, standard layouts and best practice, all leading to forms of standardisation. The potentials for tokenistic student involvement and conflict with policy aims are evident. This paper explores two issues: how to foster in young people an ethic towards future generations, and the role of co-design practices in this process. Michael Oakeshott calls teaching the conversation of mankind. In this paper, I look at the philosophy of Hannah Arendt, Emmanuel Levinas, Maurice Merleau-Ponty and Luce Irigaray to argue that investigating the ethical dilemmas of the programme through critical dialogue with students offers an approach to meeting government objectives, building sustainable schools, and fostering sustainable citizenship.

    Science.gov (United States)

    Reinhardt, John W

    2015-12-01

    Educational patient care clinics are becoming an increasingly important source of revenue for dental schools. Revenue from clinics can help offset the rising cost of dental education. In addition, those clinics represent a source of income over which the schools have reasonably direct control. Recently, a group of nine U.S. dental schools conducted a detailed financial survey of their clinics and shared the confidential results with each other. The purpose of their analysis was to develop benchmarks for key factors related to clinical financial productivity and expenses and to define best practices to guide improvements at each school. The survey found significant variations among the nine schools in revenue produced by predoctoral students and by postdoctoral residents. There were similar variations for levels of clinical staffing. By sharing the results of the survey with each other, the individual schools gained a strong understanding of the business strengths or weakness of their own clinical programs. That information gave each school's leaders the opportunity to investigate how they might improve their clinical fiscal sustainability.

    School-located influenza vaccination (SLIV) programs are a promising strategy for increasing vaccination coverage among schoolchildren. However, questions of economic sustainability have dampened enthusiasm for this approach in the United States. We evaluated SLIV sustainability of a health department led, county-wide SLIV program in Alachua County, Florida. Based on Alachua's outcome data, we modeled the sustainability of SLIV programs statewide using two different implementation costs and at different vaccination rates, reimbursement amount, and Vaccines for Children (VFC) coverage. Mass vaccination clinics were conducted at 69 Alachua County schools in 2013 using VFC (for Medicaid and uninsured children) and non-VFC vaccines. Claims were processed after each clinic and submitted to insurance providers for reimbursement ($5 Medicaid and $47.04 from private insurers). We collected programmatic expenditures and volunteer hours to calculate fixed and variable costs for two different implementation costs (with or without in-kind costs included). We project program sustainability for Florida using publicly available county-specific student populations and health insurance enrollment data. Approximately 42% (n=12,853) of pre-kindergarten - 12th grade students participated in the SLIV program in Alachua. Of the 13,815 doses provided, 58% (8042) were non-VFC vaccine. Total implementation cost was $14.95/dose or $7.93/dose if "in-kind" costs were not included. The program generated a net surplus of $24,221, despite losing $4.68 on every VFC dose provided to Medicaid and uninsured children. With volunteers, 99% of Florida counties would be sustainable at a 50% vaccination rate and average reimbursement amount of $3.25 VFC and $37 non-VFC. Without volunteers, 69% of counties would be sustainable at 50% vaccination rate if all VFC recipients were on Medicaid and its reimbursement increased from $5 to $10 (amount private practices receive). Key factors that contributed to the

  6. Where Sustainable School Meets the ‘Tthird Teacher’: Primary School Case Study From Barcelona, Spain

    Directory of Open Access Journals (Sweden)

    Marta Brkovic

    2015-07-01

    Full Text Available Participatory evaluation of aspiring sustainable schools and their pedagogical potential has recently come into focus. A few authors have made a significant start in examining schools as both environmentally and socially sustainable environments, which might simultaneously represent the ‘third teacher’. However, discussion around this idea is new in Spain. This paper describes a participatory post-occupancy study conducted with teachers and pupils in Fort Pienc School, Barcelona, Spain. Findings reveal the pedagogical potential of the school’s spaces and fabric, characterised as ‘sustainable’, and highlight the aspects that the research participants feel are performing and underperforming. The paper concludes that if we want sustainable schools to be a strategy for renovating the educational process and for leading us towards a better tomorrow globally and locally,  new models for exploring the pedagogical potential of sustainable schools should be developed and the efforts of all relevant parties synchronised; from architects to governments, from pupils to teachers.

    We determined the sustainability of effects of a school-based intervention to improve health behaviors and cardiovascular risk factors among middle school children. We administered a questionnaire and health screenings to 5 schools in Ann Arbor and 2 schools in Ypsilanti, Michigan. We assessed demographics, physiological factors, diet, physical activity, and sedentary behaviors from 1126 students who received a health curriculum (Project Healthy Schools) in the fall of sixth grade in 2005, 2006, and 2007. We administered the questionnaire and screening again in the spring and each subsequent spring through ninth grade to all available, consenting students. In the 4 years following the school-based intervention, total cholesterol, low-density lipoprotein cholesterol, and triglycerides improved, and for most years systolic and diastolic blood pressure improved. Serum glucose and body mass index did not change. Physical activity increased and sedentary behaviors diminished. Project Healthy Schools is associated with sustainable improvements in both cardiovascular parameters and healthy behaviors.

  10. An Interpretive Framework for Assessing and Monitoring the Sustainability of School Gardens

    Directory of Open Access Journals (Sweden)

    Francesco Sottile

    2016-08-01

    Full Text Available School gardens are, increasingly, an integral part of projects aiming to promote nutritional education and environmental sustainability in many countries throughout the world. In the late 1950s, FAO (Food and Agriculture Organization and UNICEF (United Nations Children's Fund had already developed projects to improve the dietary intake and behavior through school and community gardens. However, notwithstanding decades of experience, real proof of how these programs contribute to improving sustainability has not been well-documented, and reported findings have mostly been anecdotal. Therefore, it is important to begin a process of collecting and monitoring data to quantify the results and possibly improve their efficiency. This study’s primary goal is to propose an interpretive structure—the “Sustainable Agri-Food Evaluation Methodology-Garden” (SAEMETH-G, that is able to quantifiably guide the sustainability evaluation of various school garden organizational forms. As a case study, the methodology was applied to 15 school gardens located in three regions of Kenya, Africa. This application of SAEMETH-G as an assessment tool based on user-friendly indicators demonstrates that it is possible to carry out sustainability evaluations of school gardens through a participatory and interdisciplinary approach. Thus, the hypothesis that the original SAEMETH operative framework could be tested in gardens has also been confirmed. SAEMETH-G is a promising tool that has the potential to help us understand school gardens’ sustainability better and to use that knowledge in their further development all over the world.

    Leadbeater, Bonnie J; Gladstone, Emilie J; Sukhawathanakul, Paweena

    2015-09-01

    Substantial research illuminates many factors effecting the implementation of evidence-based mental health promotion programs in schools; however, research on how schools plan for sustaining their investments in these programs is limited. In this qualitative study, we elicited descriptions of opportunities and challenges for sustainability. We interviewed 24 individuals from schools involved in a longitudinal, qualitative research project that followed uptake and implementation of the evidence-based WITS Programs across 2 years (Leadbeater et al. 2012). WITS stands for Walk away, Ignore, Talk it out and Seek help and the online WITS Programs focus on preventing peer victimization ( www.witsprograms.ca ). Our findings suggest that sustainability planning in schools is not merely a next step following high quality implementation, but rather involves multiple ongoing processes that need to be anticipated and supported by school leadership and program champions and developers in order to realize investments in evidence-based programs.

    Graves, Janessa M; Finsness, Erica D; Quick, Robert; Nyando Integrated Child Health And Education Project Niche Study Team; Harris, Julie R; Daniell, William E

    School-based handwashing programs are challenging to establish and sustain, especially in low-resource settings. This qualitative study described teacher perspectives associated with implementing and sustaining a handwashing program in primary schools participating in the Nyando Integrated Child Health and Education (NICHE) project. Structured key informant interviews were conducted with teachers. Prevalent concepts and themes were grouped into themes and topic areas using an iterative, open coding approach. Forty-one teacher respondents reported favorable expectations and benefits of handwashing programs. The importance of available resources (e.g., reliable water) was cited as a primary concern. Other challenges included time and personal or institutional financial commitment necessary to ensure program sustainability. Handwashing programs in low-income, rural schools, where infrastructure is lacking and "student ambassadors" extend the intervention to the surrounding community, hold great promise to improve community health. Teachers must have adequate support and resources to implement and sustain the programs.

    Chen, Yih-Shyuan; Selwood, Ian

    This paper is a case study of a school in Taiwan. The School in this study has successfully implemented and sustained the integration of ICT across the curriculum to support teaching and learning, whilst other similar schools have failed to maintain the impetus of a national project. By using questionnaires, interviews and document analysis the leadership and management, organisational processes and decision-making, and ICT resources and technological adoption were analysed. The study highlights the importance of shared, collaborative leadership in implementing and sustaining the integrating of ICT into teaching and learning.

    Environmental responsibility in school has led to the emergence of a variety of criteria to administer green schools' contributions to sustainability. Sustainability criteria of administrative green schools need validity, reliability and norms. The aim of the current study was to develop and validate assessment criteria for green schools in Iran based on the role of academia. A national survey was conducted to obtain data on sustainability criteria initiatives for green schools and the Iranian profile was defined. An initial pool of 71 items was generated and after its first edition, 63 items were selected to comprise the sustainability criteria. Engineering-architectural and behavioral aspects of this sustainability criteria were evaluated through a sample of 1218 graduate students with environmental degrees from Iran's universities. Exploratory factor analysis using principal components and promax rotation method showed that these 9 criteria have simple structures and are consistent with the theoretical framework. The reliability coefficients of subscales ranged between 0.62 (participation) and 0.84 (building location and position). The study's survey of correlation coefficients between items and subscales illustrated that those coefficients varied between 0.24 and 0.68. Copyright © 2017 Elsevier Ltd. All rights reserved.

  4. Sustainable Architecture in the Context of Education: Reponses of Primary School Teachers on the Topical Subject

    Directory of Open Access Journals (Sweden)

    Cencič Majda

    2013-09-01

    Full Text Available The concept of sustainability and a sustainable and ecological development are common debate topics in today’s society. This paper discusses the concept of sustainability in green building with regard to schools. The research was conducted on a representative sample of primary school teachers, focusing on some of their opinions on green building. We asked them which aspect of building they favoured and how often they asked themselves certain questions about the school they taught in. Furthermore, we were interested to see whether we would find age-related differences. To this end, teachers were divided into two groups, namely, teachers of up to 35 years of age and teachers over 35. We were surprised to find that teachers over 35 had a more positive attitude towards green building in schools compared to their younger colleagues. Based on the results, we came to a conclusion that the topics pertaining to ecology and sustainable development are neglected in today’s education. However, making them part of school curriculum is not enough, as the opinions and attitudes of teachers on sustainable and ecological issues also have an important impact on the subject-matter itself.

  5. Can learning in informal settings mitigate disadvantage and promote urban sustainability? School gardens in Washington, DC

    Fisher-Maltese, Carley; Fisher, Dana R.; Ray, Rashawn

    2017-09-01

    This article explores how school gardens provide learning opportunities for school-aged children while concurrently helping cities achieve sustainability. The authors analyse this process in Washington, DC, a particularly innovative metropolis in the United States. This national capital city boasts two of the most progressive examples of legislation aimed at improving environmental awareness and inciting citizens to engage in environmental stewardship, both of which focus on school-aged children: (1) the Healthy Schools Act of 2010 and (2) the Sustainable DC Act of 2012. Together these policies focus on bringing healthy lifestyles and environmental awareness, including meaningful outdoor learning experiences, to students and families in the District of Columbia. This article is organised into three parts. The first part discusses how Washington, DC became a sustainable learning city through the implementation of these specific policies. The next part presents the results of a pilot study conducted in one kindergarten to Grade 5 (K-5) elementary school located in Ward 8, the poorest part of the city. The authors' analysis considers the support and the obstacles teachers and principals in the District of Columbia (DC) are experiencing in their efforts to integrate school gardens into the curriculum and the culture of their schools. Exploring the impacts of the school garden on the students, the local community, and the inter-generational relationships at and beyond schools, the authors aim to shed light on the benefits and the challenges. While Washington, DC is fostering its hope that the benefits prevail as it provides a model for other cities to follow, the authors also candidly present the challenges of implementing these policies. In the final part, they discuss the implications of their findings for school gardens and sustainable learning cities more broadly. They encourage further research to gain more insights into effective ways of promoting environmental

    In Turkey, as well as many other developing countries, the significance of sustainable education buildings has only recently become recognized and the issue of sustainability issue has not been sufficiently involved in laws and regulations. In this study, first of all architectural sustainability with basic design criteria has been explained. After that selected type primary school project in Turkey has been evaluated according to the sustainable design criteria. Type project of school buildings significantly limits the sustainability performance expected from buildings. It is clear that type projects shorten the planning time as they include a designing process that is independent of settlement and they are repeated in various places with different characteristics, indeed. On the other hand; abundance of disadvantages such as the overlook of the natural physical and structural properties of the location mostly restricts the sustainable design of the building. For sustainable buildings, several factors such as the environment, land, climate, insolation, direction etc. shall be taken into consideration at the beginning stage. Therefore; implementation of type projects can be deemed to be inappropriate for sustainability.

    2016-09-01

    Full Text Available Whilst school principals and educational leaders are increasingly constrained by standardized assessment results and student achievement, persistent achievement gaps continue to separate poor and historically underserved students from their wealthier mainstream peers in the United States (US and similar countries. Unprecedented levels of cultural, linguistic, ethnic, racial, and gender school diversity underscore these phenomena. As a result, leadership for ‘school improvement’ has become the norm and as evidenced by chronic academic disparities, ineffective. This review article considers culturally sustaining leadership as an innovative practice to promote and advance equity in schools.

    All municipalities in Europe have schools to manage, renovate and build. In all of these schools, hundreds of thousands of children are being taught, among other things, to be good citizens. Many boroughs and local councils have been looking to improve energy consumption in schools, with savings of up to 40% or more. A whole variety of initiatives have taken place to raise children's awareness of energy saving, renewable energy and environmental protection for sustainable urban development. This publication presents many realizations in European schools. (A.L.B.)

    A school-located mass vaccination program can enable rapid vaccination of a large number of students while minimizing disruption of their school activities. During 3 consecutive influenza seasons beginning in 2005, the Knox County Health Department conducted school-located mass vaccination clinics using live attenuated influenza vaccine. Overall, the proportion of elementary schoolchildren vaccinated with live attenuated influenza vaccine exceeded 40% each year. We describe key lessons learned in clinic operations, including obtaining informed consent, defining the organizational structure and roles, preparing the school, staffing, training, supplies, vaccine management, team communication, and data management. We conclude by discussing program costs and sustainability.

    2011-11-01

    Although sustainability is frequently described as a project goal in community-based programs, concentrated efforts to sustain interventions beyond the conclusion of research funding have only recently emerged as a focus of implementation research. The current paper describes a study of behavioral consultation to after-school program staff in low-SES, urban communities. Following consultation, staff use of four recommended tools and strategies was examined, emphasizing facilitators and barriers to sustainability. Results indicated high perceived utility and intention to use intervention components, but low sustainability at two follow-up time points within 1 year after the initial consultation concluded. Findings suggest that ongoing implementation support in community settings may be necessary to ensure the sustainability of interventions and meet the mental health needs of participating high-risk youth.

    Communication plays an important role in all aspects of the development and use of policy. We present a communication-centered perspective on the processes of enacting public health policies. Our proposed conceptual framework comprises 4 communication frames: orientation, amplification, implementation, and integration. Empirical examples from 2 longitudinal studies of school-based health policies show how each frame includes different communication processes that enable sustainable public health policy practices in school-based health initiatives. These 4 frames provide unique insight into the capacity of school-based public health policy to engage youths, parents, and a broader community of stakeholders. Communication is often included as an element of health policy; however, our framework demonstrates the importance of communication as a pivotal resource in sustaining changes in public health practices.

    We aimed to develop a cost-free and sustainable program to influence healthier eating decisions during elementary school lunch. Baseline food and beverage choices were assessed for 9 days during lunch service at two racially and economically diverse elementary schools in Spartanburg County, SC, USA. After being informed that the labeled items on the daily lunch menu represented the healthiest choice, students were allowed to ring a call bell in the cafeteria for public recognition when they chose all of the identified healthiest food and beverage items during lunch service. Using menus matched to the baseline phase, food and beverage choices were measured during a 9-day intervention phase. After 30 days, food and beverage choices were reassessed during a 3-day follow-up phase. Healthiest food & beverage choices increased 49% with >60% of students choosing non-flavored milk over flavored milk during the intervention phase. There was no difference in the success of the program between the two schools. The program continued and healthy eating decisions were significantly sustained at a 30-day follow-up assessment. Public recognition through bell ringing appears to be an effective practice to sustain increases in healthy eating decisions during elementary school lunch and warrants expansion to larger scale, longitudinal trials.

    Benner, Aprile D.; Thornton, Anna; Crosnoe, Robert

    2017-01-01

    Evidence that the learning gains of preschool fade as children transition into elementary school has led to increased efforts to sustain preschool advantages during this key transitional period. This study explores whether the observed benefits of sustainability practices for a range of child outcomes are explained and/or moderated by family and school mechanisms selecting children into experiencing these practices. Analyses of the Early Childhood Longitudinal Study-Birth Cohort revealed that both family and school factors predicted children’s exposure to several PK-3 sustainability practices. PK-3 sustainability practices were associated with reading (but not math) gains and better interpersonal skills (but not fewer externalizing behaviors) following the transition into kindergarten. These links were not conditioned by the selection mechanisms. The findings highlight who is more likely to seek out (at the family level) or offer (at the school level) sustainability practices and how relevant they are to fighting preschool fadeout.

    Razza, Rachel A.; Martin, Anne; Brooks-Gunn, Jeanne

    2011-01-01

    In this study, we examined the developmental pathways from children’s family environment to school readiness within a low-income sample (N = 1,046), with a specific focus on the role of sustained attention. Six distinct factors of the family environment representing maternal parenting behaviors, the physical home environment, and maternal mental health at 3 years of age were explored as independent predictors of children’s observed sustained attention as well as cognitive and behavioral outcomes at 5 years of age. Children were grouped by poverty status (poor vs. near-poor). Results suggest specificity in the associations among attention (focused attention and lack of impulsivity) and its correlates, with different patterns emerging by poverty status group. Overall, the family environment was largely unrelated to children’s sustained attention. For both groups, focused attention was associated with receptive vocabulary; however, it partially mediated the association between maternal lack of hostility and receptive vocabulary only among the near-poor. In addition, lack of impulsivity was associated with both receptive vocabulary and externalizing behaviors but only for the poor group. Findings indicate sustained attention as a potential target for efforts aimed at enhancing school readiness among predominantly poor children. PMID:20677860

    More than 7 million US high school students play sports. To compare practice and competition injury rates and patterns in 5 boys' sports (football, soccer, basketball, wrestling, and baseball) and 4 girls' sports (soccer, volleyball, basketball, and softball) during the 2005-2006 school year. Prospective injury surveillance study. Injury data were collected from 100 nationally representative United States high schools via High School RIO (Reporting Information Online). Athletes from participating high schools injured while participating in a school-sanctioned practice or competition in one of the above sports. Practice and competition injury rates, body site, diagnosis, and severity. High school athletes participating in these 9 sports at participating schools sustained 4350 injuries during the 2005-2006 school year, which corresponds to an estimated 1 442 533 injuries nationally. The rate of injury per 1000 athlete-exposures was higher in competition (4.63) than in practice (1.69) (rate ratio [RR] = 2.73, 95% confidence interval [CI] = 2.58, 2.90). Of all sports, football had the highest competition (12.09) and practice (2.54) injury rates per 1000 athlete-exposures. Compared with injuries sustained during practice, higher proportions of competition injuries were head/face/neck injuries (proportion ratio [PR] = 1.61, 95% CI = 1.34, 1.94), particularly in boys' soccer (PR = 7.74, 95% CI = 2.53, 23.65) and girls' basketball (PR = 6.03, 95% CI = 2.39, 15.22). Competition injuries were more likely to be concussions (PR = 2.02, 95% CI = 1.56, 2.62), especially in boys' soccer (PR = 6.94, 95% CI = 2.01, 23.95) and girls' basketball (PR = 5.83, 95% CI = 2.06, 16.49). Higher proportions of competition injuries caused the athlete to miss more than 3 weeks of play (PR = 1.28, 95% CI = 1.08, 1.52), particularly in baseball (PR = 3.47, 95% CI = 1.48, 8.11) and volleyball (PR = 2.88, 95% CI = 1.01, 8.24). Rates and patterns of high school sport injuries differed between

    Full Text Available A study to determine the impacts of farmers field schools (FFS on smallholders’ adoption of good agricultural practices in tea and to assess sustainability of smallholder tea production was conducted in the highlands of Kenya. Input-output data on tea management and on sustainability indicators (score 0-10 were collected from a sample of 120 FFS participants at the beginning of the study and from 60 randomly selected FFS participants and a comparison group of 60 non-FFS participants at the end of the study, 18 months later. The study showed that the smallholder tea systems are moving towards social sustainability and economic returns were positive. Sustainability indicator scores, for FFS members, increased by 4% from the base period. The FFS participants also attained a significantly higher level of farm sustainability, knowledge gains on good agricultural practices (GAP and higher yields and farm and tea income than their non-FFS counterparts. These findings indicate that FFS methodology had a positive contribution to enhancing farmer learning and adoption of good agricultural practices in tea and improved farmers’ livelihoods.

    School garden programmes have become popular action-oriented learning environments in many countries, often driven by converging priorities of environmental sustainability and healthful diets. Many of these programmes have assessed the impact on dietary intake, specifically fruit and vegetable intake, and related dietary behaviours, such as knowledge, preference, motivation, intention and self-efficacy to eat and prepare fruit and vegetables. The objective of the present study was twofold: (i) to review published garden-based programmes conducted in schools targeting dietary intake and/or determinants of dietary behaviour in children; and (ii) to identify similar strategies and components employed by these garden-based programmes. The review included thirteen studies that have examined the impact of garden-based programmes conducted in school, either during school hours or in after-school settings, on dietary behaviours in children (kindergarten through 8th grade students). Three of the reviewed studies did not have a comparison or control group and simply evaluated within-group changes after a garden intervention. None of the reviewed studies were randomized, but were assigned based on school's interest and timing of new school gardens being built. Out of the eleven programmes that examined dietary intake, six found that the programme resulted in increased vegetable intake, whereas four showed no effect. Seven of the eight studies that measured preference found that the programmes resulted in increased preference for vegetables. Gardening programmes also resulted in improved attitudes towards, willingness to taste, identification of and self-efficacy to prepare/cook fruit and vegetables. Similar strategies/components employed by the majority of the programmes included: 'hands on' curriculum, incorporation of a cooking component, providing the instructors, parental and stakeholder support, food provision and using the garden as the focal point for media promotion

    To assess the fiscal and logistical viability of school-based, pharmacist-administered influenza vaccination programs. Econometric observational study. Nine schools in the Rincon Unified School District, Santa Rosa, CA. Safeway Pharmacies; Rincon Unified School District; California Department of Public Health, Immunization Branch; and University of California, San Diego. Assessment of direct workflow observations and administrative data. Unit costs, productivity, and effectiveness of school-based, pharmacist-administered influenza vaccination programs. The results showed a unit cost of $23.63 (compared with $25.60 for mass vaccination and $39.79 for walk-in shot-only vaccination clinics). The productivity index ($0.88) and efficiency index ($1.12) were better compared with data reported for comparable vaccination programs. School-based, pharmacist-administered vaccination programs are fiscally and logistically self-sustaining, viable alternatives to medical office-based or community-based mass vaccination clinics, and may offer a practical strategy for vaccinating children and adolescents.

    Environmental change poses pressing challenges to public health and calls for profound and far-reaching changes to policy and practice across communities and health systems. Medical schools can act as a seedbed where knowledge, skills and innovation to address environmental challenges can be developed through innovative and collaborative approaches. The objectives of this study were to (1) explore drivers and challenges of collaboration for educational development between and within medical schools; (2) evaluate the effectiveness of a range of pedagogies for sustainable healthcare education; and (3) identify effective strategies to facilitate the renewal of medical curricula to address evolving health challenges. Participatory action research. Medical school teams participated in a nine-month collaborative project, including a one-day seminar to learn about sustainable healthcare education and develop a project plan. After the seminar, teams were supported to develop, deliver and evaluate new teaching at their medical school. New teaching was introduced at seven medical schools. A variety of pedagogies were represented. Collaboration between schools motivated and informed participants. The main challenges faced related to time pressures. Educators and students commented that new teaching was enjoyable and effective at improving knowledge and skills. Collaborative working supported educators to develop and implement new teaching sessions rapidly and effectively. Collaboration can help to build educators' confidence and capacity in a new area of education development. Different forms of collaboration may be appropriate for different circumstances and at different stages of education development. Copyright © 2017 The Royal Society for Public Health.

    Schools convene many people together for a prolonged time, facilitating spread of respiratory pathogens and amplifying epidemics. Crowded Bangladeshi schools lack the infrastructure to support optimal cough etiquette behaviors. We collected formative data on current practices from four elementary schools, and developed and piloted a low-cost cough etiquette intervention, promoting coughing and sneezing into upper sleeves at four additional schools. We trained teachers to lead behavior change sessions during regular hygiene classes for 4 weeks. We evaluated intervention acceptability, feasibility, and potential for sustainability at 1 month and at 14 months after the intervention commenced. At baseline, among 63 observed students, 58 (92%) coughed/sneezed into open air, five (8%) covered coughs/sneezes with their hands, which were not subsequently washed with soap and water as they judged this infeasible. After 4 weeks, among 70 observed students, 27 (39%) coughed/sneezed into upper sleeves, 33 (47%) into open air, and 10 (12%) covered with hands. After 14 months, among 230 observed students, 13 (6%) used upper sleeves, 154 (67%) coughed/sneezed into open air, and 59 (26%) covered with hands. Students reported that coughing/sneezing into upper sleeves was simple and protected them and their classmates from germs. This school-based intervention was acceptable and feasible, and resulted in short-term reductions in coughing/sneezing into open air, but these habits of comparatively new behavior were not sustained as teachers ceased behavior change session delivery. Strategies to support longer-term adoption of habits should be considered.

  10. Using Systems Thinking to Educate for Sustainability in a Business School

    Directory of Open Access Journals (Sweden)

    Amanda Gregory

    2014-07-01

    Full Text Available This paper explores what it means for a business school to embed systems thinking and sustainability into the curriculum by looking at both the application of systems thinking to the design of sustainable programmes and the teaching of system thinking to support understanding of sustainability. Although programmes that include systems thinking and sustainability as “bolt ons” are becoming more common, how these may best be integrated throughout the curriculum is still largely unexplored. In this paper, curriculum design is viewed through the lens of Stafford Beer’s Viable System Model; viewing the management curriculum in this way emphasises the essential interconnectedness of the subject matter rather than its reduction into blocks of knowledge that are containable within standard size teaching modules. Merely recognising the interconnected nature of management knowledge does not go far enough, though, and there is a complementary need to equip students with approaches for describing more complex and pluralistic views of the world and to address such complexities. In this paper, the specification of a module, underpinned by Flood and Jackson’s System of Systems Methodologies, that might serve to achieve these ends by introducing business students to a range of systems approaches is discussed. The challenges that realizing such an undertaking in practice might involve are also reflected on.

    Our objective was to identify individual- and organizational-level factors that affect high school teacher adoption, sustainability, and fidelity to the occupational safety and health curriculum, "Youth@Work: Talking Safety." We analyzed survey data collected from 104 high school teachers across the US who were trained in the curriculum since 2004. Linear and Cox regression were used to examine bivariate associations between individual and organizational-level factors and the outcomes of interest. Except for perceived complexity, all individual-level factors (acceptance, enthusiasm, teaching methods fit, and self-efficacy) were associated with one or more outcomes of interest (P-values ranged from sustainability and number of lessons delivered, respectively. Consistent with the literature, individual-level factors influenced teacher adoption and, to a lesser extent, sustainability, and fidelity to the Youth@Work: Talking Safety curriculum and should be considered in attempts to promote the curriculum's use in high schools. © 2015 Wiley Periodicals, Inc.

    Many cancer cells have a strong requirement for glutamine. As an aid for understanding this phenomenon the (18)F-labeled 2S,4R stereoisomer of 4-fluoroglutamine [(2S,4R)4-FGln] was previously developed for in vivo positron emission tomography (PET). In the present work, comparative enzymological studies of unlabeled (2S,4R)4-FGln and its deamidated product (2S,4R)4-FGlu were conducted as an adjunct to these PET studies. Our findings are as follows: Rat kidney preparations catalyze the deamidation of (2S,4R)4-FGln. (2,4R)4-FGln and (2S,4R)4-FGlu are substrates of various aminotransferases. (2S,4R)4-FGlu is a substrate of glutamate dehydrogenase, but not of sheep brain glutamine synthetase. The compound is, however, a strong inhibitor of this enzyme. Rat liver cytosolic fractions catalyze a γ-elimination reaction with (2S,4R)4-FGlu, generating α-ketoglutarate. Coupling of a deamidase reaction with this γ-elimination reaction provides an explanation for the previous detection of (18)F(-) in tumors exposed to [(18)F](2S,4R)4-FGln. One enzyme contributing to this reaction was identified as alanine aminotransferase, which catalyzes competing γ-elimination and aminotransferase reactions with (2S,4R)4-FGlu. This appears to be the first description of an aminotransferase catalyzing a γ-elimination reaction. The present results demonstrate that (2S,4R)4-FGln and (2S,4R)4-FGlu are useful analogues for comparative studies of various glutamine- and glutamate-utilizing enzymes in normal and cancerous mammalian tissues, and suggest that tumors may metabolize (2S,4R)4-FGln in a generally similar fashion to glutamine. In plants, yeast and bacteria a major route for ammonia assimilation involves the consecutive action of glutamate synthase plus glutamine synthetase (glutamate synthase cycle). It is suggested that (2S,4R)4-FGln and (2S,4R)4-FGlu will be useful probes in studies of ammonia assimilation by the glutamate synthase pathway in these organisms. Finally, glutamine

    2017-05-01

    Water, sanitation, and hygiene (WASH) in schools are important for child health, development, and educational performance; yet coverage in Indonesian schools remains low. To address this deficiency, UNICEF and partners conducted a WASH intervention in 450 schools across three provinces in Indonesia. A survey evaluating the sustainability of infrastructure and behavioral interventions in comparison to control districts was conducted one year after completion of the intervention. The survey data were also compared with national government data to assess the suitability of government data to report progress on the Sustainable Development Goals (SDGs). Logistic regression was used to explore associations between WASH conditions and behaviors. Intervention schools were more likely to have handwashing stations with soap and water. In multivariable analyses, schools with a toilet operation and maintenance fund were more likely to have functional toilets. Students who learn hygiene skills from their teachers were less likely to defecate openly, more likely to share hygiene knowledge with their parents, and more likely to wash their hands. Survey data were comparable with government data, suggesting that Indonesian government monitoring may be a reliable source of data to measure progress on the SDGs. This research generates important policy and practice findings for scaling up and sustaining WASH in schools and may help improve WASH in schools programs in other low-resource contexts.

    2011-05-01

    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.

    To evaluate sustained improvements 6 months after a 40-session, in-school computer attention training intervention using neurofeedback or cognitive training (CT) administered to 7- to 11-year-olds with attention-deficit/hyperactivity disorder (ADHD). One hundred four children were randomly assigned to receive neurofeedback, CT, or a control condition and were evaluated 6 months postintervention. A 3-point growth model assessed change over time across the conditions on the Conners 3-Parent Assessment Report (Conners 3-P), the Behavior Rating Inventory of Executive Function Parent Form (BRIEF), and a systematic double-blinded classroom observation (Behavioral Observation of Students in Schools). Analysis of variance assessed community-initiated changes in stimulant medication. Parent response rates were 90% at the 6-month follow-up. Six months postintervention, neurofeedback participants maintained significant gains on Conners 3-P (Inattention effect size [ES] = 0.34, Executive Functioning ES = 0.25, Hyperactivity/Impulsivity ES = 0.23) and BRIEF subscales including the Global Executive Composite (ES = 0.31), which remained significantly greater than gains found among children in CT and control conditions. Children in the CT condition showed delayed improvement over immediate postintervention ratings only on Conners 3-P Executive Functioning (ES = 0.18) and 2 BRIEF subscales. At the 6-month follow-up, neurofeedback participants maintained the same stimulant medication dosage, whereas participants in both CT and control conditions showed statistically and clinically significant increases (9 mg [P = .002] and 13 mg [P Neurofeedback participants made more prompt and greater improvements in ADHD symptoms, which were sustained at the 6-month follow-up, than did CT participants or those in the control group. This finding suggests that neurofeedback is a promising attention training treatment for children with ADHD.

    2014-06-01

    Full Text Available If we consider the role of education and its implications in the formation of a critical and conscious user of architecture, it is obvious that the development of educational strategies related to our common space and environment become fundamental. The comprehension of the concept of sustainable development is essential. Therefore, it is worth reflecting on how to develop proper programs at all educational levels to promote critical and responsible attitudes towards the common environment covering all the aspects that should shape the concepts of sustainable spatial and environmental development, enhancing at the same time great freedom regarding the formal aspects of architecture. The ideas presented in the article are supported by an empirical research on the image of architecture and the environment, held among secondary school students. The research based on the idea that one of the most efficient critical attitudes towards the world would be to develop an unconditional tie of the art work with everyday life conditions. That is why part of the activities within the research was devoted to recycling relevant architectural spaces. The results show a very heterogeneous image of architecture in the eyes of the students which sometimes overvalues contrasts and originality, disregarding tradition

    2012-06-01

    Promising approaches to the promotion of healthier eating among children in primary school settings include the opportunity to practise practical cooking and growing, promoting the take up of healthier school meals and nutritional education. However, less is known about the potential for strategies that integrate approaches through a focus on food sustainability issues--such as the promotion of awareness about local, seasonal, organic, fair trade and higher animal welfare foods. This paper presents an evaluation of the Food for Life Partnership, a multi-component programme that sought to address both the health and sustainability aspects of food. The study consisted of a two-stage cross-sectional survey of Years 5 and 6 students (ages 9-11) in 30 primary schools at enrolment and after 18-24 months, combined with an analysis of programme delivery. Higher self-reported fruit and vegetable consumption in the second stage survey was associated with a range of indicators of school participation in the programme. These included the reform of school meal procurement and preparation; experiential food growing, cooking and farm-based education and improved opportunities for stakeholder engagement. The study therefore develops a case for multilevel programmes that incorporate sustainability issues alongside experiential food education in primary school settings.

    Background Tobacco use, obesity, and physical inactivity among Louisiana’s youth pose a serious public health problem. Given the potential of school environments to affect student well-being, the Louisiana Tobacco Control Program developed and tested a pilot program, Schools Putting Prevention to Work. The objective was to assist school districts in developing a comprehensive school wellness policy and engaging their school community to generate environments that support healthful choices and behaviors. Community Context The pilot was implemented in 27 school districts, reaching an estimated 325,000 people across the state. Demographics of participating students were similar to all Louisiana’s public school students. Methods A school wellness project state team advised project development. A subgroup that included contractors and partners implemented and modified the pilot. Sites were selected though an application process. Site representatives received trainings, technical assistance, and funding to organize school-based support-building activities and coordinate a school health advisory council to develop policy and sustain healthy school environments. Project sites reported progress monthly; evaluation included data from sites and project administrators. Outcome Twenty-five comprehensive school wellness policies (covering 100% tobacco-free schools and daily physical activity and healthier cafeteria items) were approved by school boards. Environmental changes such as physical activity breaks, healthier vending options, and tobacco-free campuses were adopted. Interpretation This pilot demonstrated a successful approach to achieving policy and environmental change. The state team engaged and guided school districts to motivate students, parents, faculty/staff/administration, and businesses to establish and maintain opportunities to improve lifestyle health.

    School feeding programs are ubiquitous. Benchmarking expenditures for school feeding is an important component of program accountability and sustainability. To analyze the costs of school feeding and the cost relative to education expenditure and other measures of economic growth. Data on the costs of school feeding were collected from multiple sources, including United Nations databases, gray literature, and published reviews. Relationships between costs of school feeding, costs of education, and GDP per capita were analyzed through standard linear regression. Data on costs of school feeding were obtained for 74 countries, including 12 high-income, 40 middle-income, and 22 in low-income countries. School feeding programs were found to cost US$173 per child per year, ranging from US$54 in low-income countries to US$693 in high-income countries. In high-income countries, school feeding costs per capita were on average equivalent to 11% of the per capita investments in primary education, compared with 19% in middle-income countries and 68% in low-income countries. In middle- and low-income countries, school feeding programs covered on average 18% and 13% of the children enrolled in primary school, respectively. The total budget for school feeding in low-income countries was found to be on average 11% of the estimated total primary school education budget, compared to 4% in middle-income countries. School feeding investments are targeted in low- and middle-income settings, reaching only a portion of primary schoolchildren, with total costs only a fraction of the overall investment in education. As countries get richer, school feeding costs become a much smaller proportion of education costs. The findings of this study provide an updated framework for benchmarking school feeding programs.

    2015-10-01

    The World Health Organization currently recommends that school-based deworming programs include health hygiene education as a complementary measure. However, the sustainability and long-term impact of such hygiene education had yet to be assessed. In July 2012, this cross-sectional study was conducted in 18 primary schools in the Peruvian Amazon to gauge continuing adherence to a health hygiene education intervention introduced 2 years earlier to reduce soil-transmitted helminth infections. Due in large part to high teacher turn-over, only 9 of 47 (19.1%) teachers were still implementing the intervention. Health hygiene education interventions must, therefore, be designed to ensure sustainability in order to contribute to the overall effectiveness of school-based deworming programs.

  15. Imbalance in Spatial Accessibility to Primary and Secondary Schools in China: Guidance for Education Sustainability

    2016-11-01

    Full Text Available Compulsory education is an important aspect of the societal development. Meanwhile, education equality safeguards the effectiveness of education systems and is an important part of social equality. This study analyzes the inequality of compulsory education from the perspective of imbalanced spatial distribution. Unlike previous studies that have measured the spatial distribution of education simply based on the spatial position of primary and secondary schools, we explore spatial accessibility based on the shortest travel distance from residents to schools, and then analyze the inequality of compulsory education through the distribution of spatial accessibility. We use 2873 Chinese counties as statistical units, and perform a statistical and graphical analysis of their spatial accessibility using the Theil index and spatial autocorrelation analyses. To analyze the differences in the spatial accessibility distribution on the national and regional levels, we use three partitioned modes: the terrain partitioned mode, the economic development partitioned mode, and the province-level partitioned mode. We then analyze the spatial agglomeration characteristics and distribution patterns of compulsory education accessibility through global autocorrelation, local autocorrelation, and hot-spot and cold-spot analysis. The results demonstrate an obvious imbalance in the distribution of spatial accessibility to compulsory education at the national level. Accessibility and equality in eastern and central regions are significantly better than those in the western region; both are significantly better in coastal regions than in inland regions; and equality alone is better in the municipalities, such as Shanghai, Tianjin, and Chongqing, than in other provinces and autonomous regions. The spatial pattern analysis shows significant global autocorrelation and obvious clusters. Counties in cold-spot areas (clusters of good spatial accessibility are large in number

    This study examined the sustainability of New Moves, a school-based program aimed at decreasing weight-related problems in adolescent girls. The National Cancer Institute recognizes New Moves as a research-tested intervention program that produced positive behavioral and psychosocial outcomes. Ten schools participated in the sustainability study. Teachers completed a survey and interview, and research staff observed 1 physical education (PE) class within 2 years of the study's completion. Qualitative data were grouped by themes. Frequencies were calculated using quantitative data. All schools continued all-girls PE classes using New Moves components following the study period. Fewer schools continued the nutrition and social support classroom modules and individual coaching sessions while no schools continued lunch get-togethers. Program components were sustained in both New Moves intervention schools and control schools. Programs are most likely to be sustained if they (1) fit into the current school structure, (2) receive buy-in by teachers, and (3) require minimal additional funds or staff time. Providing control schools with minimal training and intervention resources was sufficient to continue program components if staff perceived the program was important for students' health and compatible within the school's existing infrastructure. © 2014, American School Health Association.

  1. A sample theory-based logic model to improve program development, implementation, and sustainability of Farm to School programs.

    Science.gov (United States)

    Ratcliffe, Michelle M

    2012-08-01

    Farm to School programs hold promise to address childhood obesity. These programs may increase students’ access to healthier foods, increase students’ knowledge of and desire to eat these foods, and increase their consumption of them. Implementing Farm to School programs requires the involvement of multiple people, including nutrition services, educators, and food producers. Because these groups have not traditionally worked together and each has different goals, it is important to demonstrate how Farm to School programs that are designed to decrease childhood obesity may also address others’ objectives, such as academic achievement and economic development. A logic model is an effective tool to help articulate a shared vision for how Farm to School programs may work to accomplish multiple goals. Furthermore, there is evidence that programs based on theory are more likely to be effective at changing individuals’ behaviors. Logic models based on theory may help to explain how a program works, aid in efficient and sustained implementation, and support the development of a coherent evaluation plan. This article presents a sample theory-based logic model for Farm to School programs. The presented logic model is informed by the polytheoretical model for food and garden-based education in school settings (PMFGBE). The logic model has been applied to multiple settings, including Farm to School program development and evaluation in urban and rural school districts. This article also includes a brief discussion on the development of the PMFGBE, a detailed explanation of how Farm to School programs may enhance the curricular, physical, and social learning environments of schools, and suggestions for the applicability of the logic model for practitioners, researchers, and policy makers.

    2010-08-01

    The question addressed in this paper is whether the beneficial effects of Primary School Action for Better Health (PSABH), an HIV prevention programme delivered in Kenyan primary schools, continue once students move on to secondary schools. Questionnaires were completed in December 2005 and January 2006 by all form 1-3 students in 154 randomly selected secondary schools. Students who had attended primary schools with PSABH programming were compared to those who did not on knowledge, attitudes and behaviours using multivariate regression with controls for gender, school year, religion and financial resources. Students who attended PSABH primary schools were significantly more likely to have higher levels of knowledge and attitudes that were more supportive of sexual restraint, condom use and HIV testing. They were more likely to have used several safer sex practices and to have been tested for HIV. The effects were strongest in the first year of secondary school and decreased thereafter. PSABH continues to have a beneficial effect for students who continue to secondary school. Copyright 2009 The Association for Professionals in Services for Adolescents. Published by Elsevier Ltd.

    Interventions that enhance linkages between healthy diets and local agriculture can promote sustainable food systems. Home-grown school feeding programs present a promising entry point for such interventions, through the delivery of nutritious menus and meals. To describe the adaptation of the School Meals Planner Package to the programmatic and environmental reality in Ghana during the 2014 to 2015 school year. Guided by a conceptual framework highlighting key considerations and trade-offs in menu design, an open-source software was developed that could be easily understood by program implementers. Readily available containers from markets were calibrated into "handy measures" to support the provision of adequate quantities of food indicated by menus. Schools and communities were sensitized to the benefits of locally sourced, nutrient-rich diets. A behavior change communication campaign including posters and songs promoting healthy diets was designed and disseminated in schools and communities. The School Meals Planner Package was introduced in 42 districts in Ghana, reaching more than 320 000 children. Monitoring reports and feedback on its use were positive, demonstrating how the tool can be used by planners and implementers alike to deliver nutritious, locally-sourced meals to schoolchildren. The value of the tool has been recognized at the highest levels by Ghana's government who have adopted it as official policy. The School Meals Planner Package supported the design of nutritious, locally sourced menus for the school feeding program in Ghana. The tool can be similarly adapted for other countries to meet context-specific needs. © The Author(s) 2016.

    2012-04-01

    The scope of this study was to discuss the administrative sustainability of Brazil's Vocational Health Schools (ETSUS) based on the principle of teaching and service integration, which brings a new dimension to healthcare work as yet unregulated by Brazilian public administration. It was a qualitative study using case study methodology. The research involved a semi-structured questionnaire given to ETSUS managers addressing institutional, administrative, and work management aspects. The sample was composed of 6 ETSUS that belong to the Network of Vocational Health Schools (RET-SUS). The ETSUS showed centralized planning and management, and decentralized implementation of their core activities. The majority did not have administrative autonomy and relied heavily on funding from the federal government. According to ETSUS managers, the lack of regulation of teaching activities by civil servants weakens the management of ETSUS. The ETSUS have managerial problems related to teaching-service integration, which has to be regulated in order to guarantee the sustainability of these schools and avoid conflicts with Brazilian legislation.

  10. The School Gardens in Preserving Biological Diversity for Education of Sustainable Development

    Directory of Open Access Journals (Sweden)

    2009-12-01

    Full Text Available In the teaching-learning process, a school garden allows to fully cover the contents of biology and environment protection curricular basic requirements. The role and importance of school gardens increased immediately after WW II but later the idea of these school structures waned. However, today we come back to the creation of school gardens and incorporating them in the educational process. A school garden fulfills a great didactic and tutorial function. At the same time, it allows to connect theory with practice. It enables teachers to conduct classes in the open air in “a green classroom”. Didactic literature quotes that the use of school gardens in teaching and learning of biology increases the effectiveness of the educational process. The analysis of reports of students of IV Biology at the Natural Sciences Department of Szczecin University, who have conducted classes in a school Botanical Garden of Primary School No. 61 in Szczecin, shows the huge role of a school garden in the teaching-learning process. The students conclude that a school garden gives them an opportunity for direct contact with nature. The garden develops pupils’ talents and interests and teaches them to conduct ecological and phono-logical observations.

    2017-12-12

    There is little agreement among governments, institutions, scientists and food activists as to how to best tackle the challenging issues of health and sustainability in the food sector. This essay discusses the potential of school meals as a platform to promote healthy and sustainable food behavior. School meal programs are of particular interest for improving public diet because they reach children at a population scale across socio-economic classes and for over a decade of their lives, and because food habits of children are more malleable than those of adults. Current research on the history and health implications of school meal programs is reviewed in a cross-national comparative framework, and arguments explored that speak for the need of a new developmental phase of school meals as an integrative learning platform for healthy and sustainable food behavior. Nutritional, social, practical, educational, economical, political, and cultural perspectives and challenges linked to the implementation of healthy and sustainable school meals are discussed. Finally, the need for long-term interventions and evaluations is highlighted and new research directions are proposed.

    2013-03-01

    Full Text Available There is increasing interest in the role that schools can play in promoting education for sustainable development (ESD, and evidence is emerging that schools can be influential in the emerging agenda around the ecological, ethical and social aspects of food, diet and nutrition. With regard to such food sustainability issues, this paper analyses the role of the Food for Life Partnership national programme in supporting garden and farm-based learning activities in 55 primary schools in England, UK. Using a mixed methods approach, the study examined the programme’s implementation through staff perceptions and a range of school change indicators. The study found that the programme delivery was associated with widespread institutional reforms. According to staff, implementation of the programme provided a range of opportunities for pupils to learn about food production and sustainability, but addressing these issues was challenging for teachers and raised a number of questions concerned with effective, equitable and on-going implementation. At a pedagogical level, teachers also reflected on conceptually challenging aspects of food sustainability as a topic for primary school education. The study identified ways that ESD programmes could support schools to think about and implement learning opportunities as well as identifying significant barriers related to resourcing such programmes.

    Full Text Available The youth, especially school going children, are the future of any society. It is therefore important that children should receive adequate healthcare support at an early age in order to strive to preserve and ensure better education and welfare of the children and continuity in societal success. Despite the strategic initiatives that aim at improving the general health of school going children, such as South Africa’s Integrated School Health Policy, there still exist challenges in support programmes meant to alleviate the barriers to effective healthcare towards improved education for the school children. Advances in ICT enable a fundamental redesign of healthcare processes based on the use and integration of electronic communication at all levels. New communication technologies can support a transition from institution centric to user-centric applications. This paper defines key principles and challenges for designers, policy makers, and evaluators of user-centred technologies for healthcare in schools. The paper employs the User Experience Management Model (UXM2 to review the current and emerging trends, and highlights challenges related to the design of a typical m-ICT application that supports delivery of healthcare in schools. The paper reaches conclusions for next steps that will advance the domain.

    2009-08-01

    With the intention of bridging the 'digital divide' many programmes have been launched to provide computers for educational institutions, ranging from refurbishing second hand computers to delivering low cost new computers. The fast and economical provision of large quantities of equipment is one of the many challenges faced by such programmes. If an increase is to be achieved in the sustainability of computer supplies for schools, not only must equipment be provided, but also suitable training and maintenance delivered. Furthermore, appropriate recycling has to be ensured, so that end-of-life equipment can be dealt with properly. This study has evaluated the suitability of three computer supply scenarios to schools in Colombia: (i) 'Colombian refurbishment', -refurbishment of computers donated in Colombia, (ii) 'Overseas refurbishment', -import of computers which were donated and refurbished abroad, and (iii) 'XO Laptop', -purchase of low cost computers manufactured in Korea. The methods applied were: Material Flow Assessment, -to assess the quantities-, Life Cycle Assessment, -to assess the environmental impacts, and the application of the Multiple Attribute Utility Theory, -to analyse, evaluate and compare different scenarios. The most sustainable solution proved to be the local refurbishment of second hand computers of Colombian origin to an appropriate technical standard. The environmental impacts of such practices need to be evaluated carefully, as second hand appliances have to be maintained, require spare parts and sometimes use more energy than newer equipment. Providing schools with second hand computers from overseas and through programmes such as 'One Laptop Per Child' has the disadvantage that the potential for social improvements - such as creation of jobs and local industry involvement - is very low.

    Full Text Available This study investigated the extent to which junior secondary school students in Port Harcourt Local Government Area of Rivers State Nigeria are aware of issues related to climate change and sustainable development. The study adopted a descriptive survey design. Four research questions were raised. Two instruments were used for data collection, a questionnaire and the junior secondary school teaching syllabus. The questionnaire titled “ Climate change and Sustainable Development Awareness Questionnaire” (CCSDA was used to obtain data from 1600 junior secondary school three (JSS3 students from the fourteen junior secondary schools in Port Harcourt Local Government of Rivers State, Nigeria. The questionnaire had three sections; A, B and C. Section A obtained the demographic features and bio-data of students, section B obtained information on the awareness level of climate change while section C obtained information on sustainable development awareness level. Simple percentages and mean were used to answer the research questions. The results from the data analysis revealed among other things that the JSS curriculum coverage of climate change is small; there is no sustainable development issues in the teaching syllabus of JSS; the level of awareness of sustainable Development issues is low; even though the climate change issues awareness level is high but the knowledge is low; students are eager and willing to know more about climate change and sustainable development issues. Based on these results, the researcher recommended among other things that more themes on Climate change and sustainable development should be introduced in social studies and integrated science in all the JSS level. Having very few topics on climate change and none at all on sustainable development at the junior secondary level is dangerous at this level of their development and more especially now that the world is striving to attain the Millennium Development Goals (MDGs.

    2017-08-02

    Approximately 300,000 U.S. adolescents sustain concussions annually while participating in organized athletics. This study aimed to track sex and sport-specific trends among high school sports-related concussions over time, to identify whether a particular sport predisposes athletes to a higher risk, and to assess whether traumatic brain injury law enactments have been successful in improving recognition. Injury data for academic years 2005 to 2014 were collected from annual reports generated by High School RIO (Reporting Information Online). The relative proportions of total estimated concussions to total estimated injuries were compared using an injury proportion ratio. The concussion rate was defined as the number of concussions per 10,000 athlete exposures (1 athlete participating in 1 practice or competition), with rates compared using a rate ratio. To evaluate the impact of legislation on sports-related concussions in this population, trends in concussion rates and proportions were analyzed before enactment (academic years 2005-2009) and after enactment (academic years 2010-2014). Between 2005-2006 and 2014-2015, a significant increase (p concussions for all sports combined, the overall concussion rate (rate ratio, 2.30 [95% confidence interval, 2.04 to 2.59]), and the overall proportion of concussions (injury proportion ratio, 2.68 [95% confidence interval, 2.66 to 2.70]) was seen. Based on the injury proportion ratio, during the 2014-2015 academic year, concussions were more common in girls' soccer than in any other sport (p concussion prevention and recognition measures continue to be emphasized in high school contact sports. The data in our study suggest that significant increases in the overall rate and proportion of reported concussions during the past decade could have been affected by traumatic brain injury legislation. To our knowledge, this is the first study to show that girls' soccer players may have an even greater risk of sustaining a concussion

    Sowers, T. Shane

    2012-01-01

    This paper describes a User Guide for the Systematic Sensor Selection Strategy (S4). S4 was developed to optimally select a sensor suite from a larger pool of candidate sensors based on their performance in a diagnostic system. For aerospace systems, selecting the proper sensors is important for ensuring adequate measurement coverage to satisfy operational, maintenance, performance, and system diagnostic criteria. S4 optimizes the selection of sensors based on the system fault diagnostic approach while taking conflicting objectives such as cost, weight and reliability into consideration. S4 can be described as a general architecture structured to accommodate application-specific components and requirements. It performs combinational optimization with a user defined merit or cost function to identify optimum or near-optimum sensor suite solutions. The S4 User Guide describes the sensor selection procedure and presents an example problem using an open source turbofan engine simulation to demonstrate its application.

  12. Improvement of the Sustainability of Existing School Buildings According to the Leadership in Energy and Environmental Design (LEED® Protocol: A Case Study in Italy

    Directory of Open Access Journals (Sweden)

    2013-12-01

    Full Text Available School-age students spend much of their time in school buildings. The sustainability of these buildings should be a priority as better comfort with a high indoor air quality contributes to an improvement in the conditions for learning. Although new school buildings are often built with high standards of sustainability and energy efficiency, the existing school building stock is generally characterised by very poor quality. The energy retrofit of existing school buildings in recent years is part of the policies of the European Union and, consequently, of the Member States. However, rarely do these measures consider aspects other than energy. This paper proposes and discusses a feasibility study which provides a considerable improvement in the environmental quality of 14 school buildings located in northern Italy: the objective is to ensure the requirements for Leadership in Energy and Environmental Design (LEED® certification. The analysis considers both the technical and economic aspects. The study shows that there is a technical feasibility: the credits are between 42 and 54, moreover the major cost (the cost of building envelope and heating systems retrofit is 82.9% of the total cost is due to the improvement of energy efficiency. The improvement of sustainability is therefore a reasonable strategy even if the application of the LEED Protocol in the Italian context involves some critical issues that are discussed in the paper.

    2014-03-01

    Full Text Available There is a rising awareness of the power of the public sector in enhancing sustainable consumption and production practices, in particular related to food procurement and its social, ethical, economical and environmental implications. School meal services have a high resonance in the debate on collective catering services because of the implications on the education to sustainable dietary habits and the orientation of the production system. This contribution focuses on the reciprocal relationship between professionals and users of school meal services as a driver to mobilize new resources—according to the theory of co-production—that steer service innovation and a shift towards more sustainable practices. We illustrate this through a case study on the school meal system in Pisa (Italy, where the Canteen Committee represents an institutional arena for participation and empowerment of actors that has gradually gained a central role in shaping this school meal service. Despite the challenges and obstacles, the institutionalized co-production of services allows consolidation of trust among key players and the introduction of innovations in the service, in the form of several projects oriented to sustainability which would not take place without the joint effort of actors involved, parents in the first place.

    Although innovations in space education were introduced in many developing countries with good intentions, too many changes and challenges in the existing system have often penalized those who needed them the most. Consequently, the students and teachers in the underprivileged schools face isolation, neglect and coupled with inadequate pedagogic attention, poor infrastructure and insufficient resources, inadvertently suffer. Surprisingly, these deprived school students possess cognitive capabilities of comprehending nature. One of the most compelling situations in Indian school education is that the syllabus is often modified haphazardly without the necessary groundwork and infrastructure to implement it. Apparently, there has neither been teaching nor learning on applied knowledge. Despite the growth in communication and technology applications in space education, inequalities continue to exist in developing countries. In our present society many crucial services are provided by space and it becomes imperative that students have a comprehensive knowledge of space and space based technologies. To realize these objectives, we have adopted a comprehensive and holistic capacity building mechanism which incorporates differentiated instructional strategy on teaching space education in underprivileged schools. Because differentiation and scaffolding techniques yield similar instructional goals, we have blended together both the approaches to the point of being indistinguishable and this proved successful. Initiation was done through the setting up of an Astronomy Club in a backward area in Hyderabad and necessary infrastructure was provided by one of the authors. A state of the art audio-visual room with LCD Projector for ICT mode of presentations of various astronomy and space topics, having a seating capacity of 50 students is in place.

    CMB-S4 is a proposed experiment to map the polarization of the Cosmic Microwave Background (CMB) to nearly the cosmic variance limit for the angular scales that are accessible from the ground. The science goals and capabilities of CMB-S4 in illuminating cosmic inflation, measuring the sum of neutrino masses, searching for relativistic relics in the early universe, characterizing dark energy and dark matter, and mapping the matter distribution in the universe have been described in the CMB-S4 Science Book. This Technology Book is a companion volume to the Science Book. The ambitious science goals of the proposed "Stage-IV" CMB-S4 will require a step forward in experimental capability from the current Stage-III experiments. To guide this process, the community summarized the current state of the technology and identify R&D efforts necessary to advance it for possible use in CMB-S4. The book focused on the technical challenges in four broad areas: Telescope Design; Receiver Optics; Focal-Plane Optical Coupling; and Focal-Plane Sensor and Readout.

    NiCo2S4 is a technologically important electrode material that has recently achieved remarkable performance in pseu-docapacitor, catalysis, and dye-synthesized solar cell applications.[1-5] Essentially, all reports on this material have pre-sumed it to be semiconducting, like many of the chalcogenides, with a reported band-gap in the range of 1.2-1.7 eV.[6,7] In this report, we have conducted detailed experimental and theoretical studies, most of which done for the first time, which overwhelmingly show that NiCo2S4 is in fact a metal. We have also calculated the Raman spectrum of this mate-rial and experimentally verified it for the first time, hence clarifying inconsistent Raman spectra reports. Some of the key results that support our conclusions include: (1) the measured carrier density in NiCo2S4 is 3.18×1022 cm-3, (2) Ni-Co2S4 has a room temperature resistivity of around 103 µΩ cm which increases with temperature, (3) NiCo2S4 exhibits a quadratic dependence of the magnetoresistance on magnetic field, (4) thermopower measurements show an extremely low Seebeck coefficient of 5 µV K-1, (5) first principles calculations confirm that NiCo2S4 is a metal. These results sug-gest that it is time to re-think the presumed semiconducting nature of this promising material. They also suggest that the metallic conductivity is another reason (besides the known significant redox activity) behind the excellent perfor-mance reported for this material.

    This study investigated the extent to which parental Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms impact child and parent outcomes following a multimodal family-school intervention, the Family School Success (FSS) program, when compared to an active-control condition (CARE). Participants were 139 children with ADHD (67% male; 91% non-Hispanic; 77% Caucasian; Grades 2-6) and their primary caretaker (91% female; ages 26-59) who participated in a randomized clinical trial evaluating the efficacy of FSS. Associations were examined between parent-reported ADHD symptoms at baseline and intervention outcomes reported by parents and teachers after treatment and at a 3-month follow-up, including child homework and classroom impairments, child ADHD and oppositional defiant disorder symptoms, parenting behaviors, and parent-teacher relationship quality. Across both treatment conditions, parental ADHD was not associated with parent or child outcomes at postassessment. However, differences emerged between the two treatment groups at follow-up for parents with ADHD, particularly when an empirically supported symptom cutoff was used to identify parents at risk for having ADHD. In FSS, but not in CARE, parental ADHD was associated with declines in treatment gains in the quality of the parent-teacher relationship and the child's homework performance. Parents at risk for ADHD had difficulty maintaining treatment effects for themselves and their child in the FSS intervention but not in CARE. The supportive and educational components central to the CARE intervention may be helpful in promoting the sustainability of psychosocial interventions for children with ADHD who have parents with elevated ADHD symptoms.

Data were analyzed to calculate rates, assess patterns, and evaluate potential risk factors for player-to-player contact injuries. A total of 34,532 injuries in boys' football, ice hockey, and lacrosse occurred during 9,078,902 athlete-exposures (AEs), for a rate of 3.80 injuries per 1000 AEs in the 3 contact sports of interest. The risk of injuries was found to be greater in competition compared with practice for all 3 sports, with the largest difference in ice hockey (rate ratio, 8.28) and the smallest difference in lacrosse (rate ratio, 3.72). In all 3 contact sports, the most commonly injured body site in competition and practice caused by both tackling/checking and being tackled/checked was the head/face. However, a significantly greater proportion of concussions sustained in football were the result of tackling compared with being tackled (28.2% vs 24.1%, respectively). In addition, a significantly greater proportion of concussions were sustained in competition compared with practice for all 3 sports. This study is the first to collectively compare injury rates and injury patterns sustained from intentional player-to-player contact in boys' high school football, ice hockey, and lacrosse. Notably, there was a relatively high risk of injuries and concussions during football practices.

    European control and prevention policies are focused to guarantee a high level of protection of consumers' health. Food-borne diseases as obesity, diabetes, food allergy, and food-borne outbreaks are increasing. To prevent food-borne diseases, it is fundamental to involve consumers, in particular children, in educational experiences aimed to learn the proper behaviours to be applied. In this context, we designed and performed 5 educational workshops about food safety, hidden allergens in food and nutrition aimed to involve children attending primary and summer school. These experiences let us collect observations about children knowledge and behaviours. From May to October 2015, a total of 1708 children aged 6 to 11 years joined our workshops. Children were involved in listening activities, laboratory experiments, handling games and sensory experiences. All participants were familiar with food allergy and were interested to know how to behave with allergic people. Children showed great curiosity in discovering that many foods normally contain live bacteria. Less than 25% of children reported to skip breakfast, to have it watching TV or to spend few minutes for it. Many of them (>75%) thought that fruits and vegetables are all year-round available and are not related to a specific period. Very few participants (<25%) knew that freezing is the treatment to be applied to make fresh fish safe from parasites. Children involved in food safety and nutrition educational experiences have the opportunity to increase their awareness about the correct behaviours to prevent food-borne diseases and to improve their own critical thinking about food consumption.

    Obesity prevention interventions targeting 'at-risk' adolescents are urgently needed. The aim of this study is to evaluate the sustained impact of the 'Active Teen Leaders Avoiding Screen-time' (ATLAS) obesity prevention program. Cluster RCT in 14 secondary schools in low-income communities of New South Wales, Australia. Participants were 361 adolescent boys (aged 12-14 years) 'at risk' of obesity. The intervention was based on Self-Determination Theory and Social Cognitive Theory and involved: professional development, fitness equipment for schools, teacher-delivered physical activity sessions, lunch-time activity sessions, researcher-led seminars, a smartphone application, and parental strategies. Assessments for the primary (body mass index [BMI], waist circumference) and secondary outcomes were conducted at baseline, 8- (post-intervention) and 18-months (follow-up). Analyses followed the intention-to-treat principle using linear mixed models. After 18-months, there were no intervention effects for BMI or waist circumference. Sustained effects were found for screen-time, resistance training skill competency, and motivational regulations for school sport. There were no clinically meaningful intervention effects for the adiposity outcomes. However, the intervention resulted in sustained effects for secondary outcomes. Interventions that more intensively target the home environment, as well as other socio-ecological determinants of obesity may be needed to prevent unhealthy weight gain in adolescents from low-income communities.

    This book lays out the scientific goals to be addressed by the next-generation ground-based cosmic microwave background experiment, CMB-S4, envisioned to consist of dedicated telescopes at the South Pole, the high Chilean Atacama plateau and possibly a northern hemisphere site, all equipped with new superconducting cameras. CMB-S4 will dramatically advance cosmological studies by crossing critical thresholds in the search for the B-mode polarization signature of primordial gravitational waves, in the determination of the number and masses of the neutrinos, in the search for evidence of new light relics, in constraining the nature of dark energy, and in testing general relativity on large scales.

    2006-10-01

    A combined school- and community-based campaign targeting the entire school-age population of Burkina Faso with drugs against schistosomiasis (praziquantel) and soil-transmitted helminthiasis (albendazole) was implemented in 2004-2005. In total, 3,322,564 children from 5 to 15 years of age were treated, equivalent to a 90.8% coverage of the total school-age population of the country. The total costs of the campaign were estimated to be US 1,067,284 dollars, of which 69.4% was spent on the drugs. Delivery costs per child treated were US 0.098 dollar, in the same range as school-based only interventions implemented in other countries; total costs per child treated (including drugs) were US 0.32 dollar. We conclude that a combined school- and community-based strategy is effective in attaining a high coverage among school-age children in countries where school enrolment is low and where primary schools cannot serve as the exclusive drug distribution points. The challenge for Burkina Faso will now be to ensure the sustainability of these disease control activities.

    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.

    We review exact results in {{ N}}=2 supersymmetric gauge theories defined on S 4 and its deformation. We first summarize the construction of rigid SUSY theories on curved backgrounds based on off-shell supergravity, then explain how to apply the localization principle to supersymmetric path integrals. Closed formulae for partition function as well as expectation values of non-local BPS observables are presented. This is a contribution to the review issue ‘Localization techniques in quantum field theories’ (ed V Pestun and M Zabzine) which contains 17 chapters available at [1].

    2008-03-01

    Full Text Available Abstract Background HIV/AIDS resource allocation decisions are influenced by political, social, ethical and other factors that are difficult to quantify. Consequently, quantitative models of HIV/AIDS resource allocation have had limited impact on actual spending decisions. We propose a decision-support System for HIV/AIDS Resource Allocation (S4HARA that takes into consideration both principles of efficient resource allocation and the role of non-quantifiable influences on the decision-making process for resource allocation. Methods S4HARA is a four-step spreadsheet-based model. The first step serves to identify the factors currently influencing HIV/AIDS allocation decisions. The second step consists of prioritizing HIV/AIDS interventions. The third step involves allocating the budget to the HIV/AIDS interventions using a rational approach. Decision-makers can select from several rational models of resource allocation depending on availability of data and level of complexity. The last step combines the results of the first and third steps to highlight the influencing factors that act as barriers or facilitators to the results suggested by the rational resource allocation approach. Actionable recommendations are then made to improve the allocation. We illustrate S4HARA in the context of a primary healthcare clinic in South Africa. Results The clinic offers six types of HIV/AIDS interventions and spends US$750,000 annually on these programs. Current allocation decisions are influenced by donors, NGOs and the government as well as by ethical and religious factors. Without additional funding, an optimal allocation of the total budget suggests that the portion allotted to condom distribution be increased from 1% to 15% and the portion allotted to prevention and treatment of opportunistic infections be increased from 43% to 71%, while allocation to other interventions should decrease. Conclusion Condom uptake at the clinic should be increased by

    Full Text Available Small variations of the entanglement entropy δS and the expectation value of the modular Hamiltonian δE are computed holographically for circular entangling curves in the boundary of AdS4, using gravitational perturbations with general boundary conditions in spherical coordinates. Agreement with the first law of thermodynamics, δS=δE, requires that the line element of the entangling curve remains constant. In this context, we also find a manifestation of electric–magnetic duality for the entanglement entropy and the corresponding modular Hamiltonian, following from the holographic energy–momentum/Cotton tensor duality.

    Much attention has been paid to hospitals environments since modern pandemics have emerged. The building sector is considered to be the largest world energy consumer, so many global organizations are attempting to create a sustainable environment in building construction by reducing energy consumption. Therefore, maintaining high standards of hygiene while reducing energy consumption has become a major task for hospitals. This study develops a decision model based on genetic algorithms and A* graph search algorithms to evaluate existing hospital environmental conditions and to recommend an optimal scheme of sustainable renovation strategies, considering trade-offs among minimal renovation cost, maximum quality improvement, and low environmental impact. Reusing vacant buildings is a global and sustainable trend. In Taiwan, for example, more and more school space will be unoccupied due to a rapidly declining birth rate. Integrating medical care with local community elder-care efforts becomes important because of the aging population. This research introduces a model that converts a simulated vacant school building into a community public hospital renovation project in order to validate the solutions made by hospital managers and suggested by the system. The result reveals that the system performs well and its solutions are more successful than the actions undertaken by decision-makers. This system can improve traditional hospital building condition assessment while making it more effective and efficient.

  6. A natural S 4 × SO(10) model of flavour

    Björkeroth, Fredrik; de Anda, Francisco J.; King, Stephen F.; Perdomo, Elena

    2017-10-01

    We propose a natural S 4 × SO(10) supersymmetric grand unified theory of flavour with an auxiliary Z_4^2× Z_4^R symmetry, based on small Higgs representations (nothing larger than an adjoint) and hence a type-I seesaw mechanism. The Yukawa structure of all fermions is determined by the hierarchical vacuum expectation values of three S 4 triplet flavons, with CSD3 vacuum alignments, where up-type quarks and neutrinos couple to one Higgs 10, and the down-type quarks and charged leptons couple to a second Higgs 10. The Yukawa matrices are obtained from sums of low-rank matrices, where each matrix in the sum naturally accounts for the mass of a particular family, as in sequential dominance in the neutrino sector, which predicts a normal neutrino mass hierarchy. The model accurately fits all available quark and lepton data, with predictions for the leptonic CP phase in 95% credible intervals given by 281° Higgs doublets emerging from the two Higgs 10s without mixing, and we demonstrate how a μ term of O(TeV) can be realised, as well as doublet-triplet splitting, with Planck scale operators controlled by symmetry, leading to acceptable proton decay.

    The development and deployment of data processing systems to process Earth Observing System (EOS) data has proven to be costly and prone to technical and schedule risk. Integration of science algorithms into a robust operational system has been difficult. The core processing system, based on commercial tools, has demonstrated limitations at the rates needed to produce the several terabytes per day for EOS, primarily due to job management overhead. This has motivated an evolution in the EOS Data Information System toward a more distributed one incorporating Science Investigator-led Processing Systems (SIPS). As part of this evolution, the Goddard Earth Sciences Distributed Active Archive Center (GES DAAC) has developed a simplified processing system to accommodate the increased load expected with the advent of reprocessing and launch of a second satellite. This system, the Simple, Scalable, Script-based Science Processor (S42) may also serve as a resource for future SIPS. The current EOSDIS Core System was designed to be general, resulting in a large, complex mix of commercial and custom software. In contrast, many simpler systems, such as the EROS Data Center AVHRR IKM system, rely on a simple directory structure to drive processing, with directories representing different stages of production. The system passes input data to a directory, and the output data is placed in a "downstream" directory. The GES DAAC's Simple Scalable Script-based Science Processing System is based on the latter concept, but with modifications to allow varied science algorithms and improve portability. It uses a factory assembly-line paradigm: when work orders arrive at a station, an executable is run, and output work orders are sent to downstream stations. The stations are implemented as UNIX directories, while work orders are simple ASCII files. The core S4P infrastructure consists of a Perl program called stationmaster, which detects newly arrived work orders and forks a job to run the

    Risk of dental injuries is present in a variety of sports. Mouthguards are effective yet underutilized. This study aimed to estimate the rate of dental injuries among high school athletes and investigate the utilization of mouthguards across multiple high school sports. Athlete exposure and dental injury data were collected during the 2008/2009 through 2013/2014 academic years from a large sample of high schools in the United States as part of the National High School Sports-Related Injury Surveillance Study. There were 222 dental injuries sustained during 24,787,258 athlete exposures for a rate of 0.90 per 100,000 athlete exposures. The rate of dental injuries in competition (1.8) was three times higher than the rate in practice (0.6) (RR: 3.1, 95% CI: 2.3-4.0). Rates of dental injuries varied by sport with the highest rates in girls' field hockey (3.9) and boys' basketball (2.6). Dental injuries most commonly occurred as a result of contact with another player (61.3%) and contact with a playing apparatus (31.5%). For the majority of dental injuries, the athlete was not wearing a mouthguard (72.5%). Among injuries where athletes were wearing mouthguards, the majority were self-fitted (95.9%). Although dental injuries were relatively uncommon, the majority occurred while the athlete was not wearing a mouthguard. As previous studies have shown that mouthguards are effective in preventing injuries, all high school athletes participating in a sport that places them at risk of sustaining a dental injury should wear a mouthguard consistently in both competition and practice. © 2015 John Wiley & Sons A/S.

    We describe S4, a free implementation of the Fourier modal method (FMM), which has also been commonly referred to as rigorous coupled wave analysis (RCWA), for simulating electromagnetic propagation through 3D structures with 2D periodicity. We detail design aspects that allow S4 to be a flexible platform for these types of simulations. In particular, we highlight the ability to select different FMM formulations, user scripting, and extensibility of program capabilities for eigenmode computations.

    Anti-self-dual (ASD) solutions to the Yang-Mills equation (or instantons) over an anti-self-dual 4-manifold, which are invariant under an appropriate action of a three-dimensional Lie group, give rise, via twistor construction, to isomonodromic deformations of connections on CP having four simple singularities. As is well known, such deformations are governed by the sixth Painlevé equation P VI(α,β,γ,δ). We work out the particular case of the SU-action on S4, obtained from the irreducible representation on R5. In particular, we express the parameters (α,β,γ,δ) in terms of the instanton number. The present paper contains the proof of the result announced in [Richard Muñiz Manasliski, Painlevé VI equation from invariant instantons, in: Geometric and Topological Methods for Quantum field theory, Contemp. Math., vol. 434, Amer. Math. Soc., Providence, RI, 2007, pp. 215-222].

    Cosmic microwave background (CMB) full-sky temperature data show a hemispherical asymmetry in power nearly aligned with the Ecliptic. In real space, this anomaly can be quantified by the temperature variance in the Northern and Southern Ecliptic hemispheres, with the Northern hemisphere displaying an anomalously low variance while the Southern hemisphere appears unremarkable [consistent with expectations from the best-fitting theory, Lambda Cold Dark Matter (ΛCDM)]. While this is a well-established result in temperature, the low signal-to-noise ratio in current polarization data prevents a similar comparison. This will change with a proposed ground-based CMB experiment, CMB-S4. With that in mind, we generate realizations of polarization maps constrained by the temperature data and predict the distribution of the hemispherical variance in polarization considering two different sky coverage scenarios possible in CMB-S4: full Ecliptic north coverage and just the portion of the North that can be observed from a ground-based telescope at the high Chilean Atacama plateau. We find that even in the set of realizations constrained by the temperature data, the low Northern hemisphere variance observed in temperature is not expected in polarization. Therefore, observing an anomalously low variance in polarization would make the hypothesis that the temperature anomaly is simply a statistical fluke more unlikely and thus increase the motivation for physical explanations. We show, within ΛCDM, how variance measurements in both sky coverage scenarios are related. We find that the variance makes for a good statistic in cases where the sky coverage is limited, however, full northern coverage is still preferable.

    Engaging young people in the design and delivery of mental health education could lead to more effective interventions; however, few of these interventions have been evaluated. This study aimed to gain preliminary evidence with regards to the efficacy and acceptability of OpenMinds: a peer-designed and facilitated mental health literacy programme for university and secondary school students. The programme involves a structured programme of education and training for university medical students, who then deliver workshops in secondary schools. Pre- and post-surveys were completed by 234 school students who received two workshops and 40 university medical students who completed the OpenMinds programme and delivered the workshops. The main outcomes in both groups were components of mental health literacy (non-stigmatising attitudes, knowledge, social distance and helping attitudes). Perceived teaching efficacy and interest in mental health careers (university medical students) and workshop acceptability (school students) were also examined. University and school student participation in OpenMinds was associated with significant improvements in three of four mental health literacy elements in both samples. Knowledge and attitudes improved in both samples, social distance improved only in the university sample and knowledge of helping behaviours increased in the school sample. University students' perceived teaching efficacy improved but there was no change in their reported interest in pursuing psychiatry in their career. Acceptability was high; over 70% of the school students agreed that they enjoyed the workshops and liked being taught by a university student. This study provides preliminary evidence for the acceptability and efficacy of OpenMinds as a sustainable peer-led model of mental health education for young people. The OpenMinds programme is ready for efficacy testing in a randomised trial.

    School lunch is not provided in public elementary schools in Indonesia, and students frequently buy and eat snacks at school. We hypothesized that providing a traditional Sundanese meal as school lunch would be beneficial for children in rural West Java. To test this hypothesis, we evaluated the effect of a 1-month school lunch intervention aiming at sustainability and based on children's nutritional intake, hemoglobin and hematocrit levels, and body mass index (BMI). A lunch (including rice, vegetable dish, animal protein dish, plant protein dish, and fruit) containing one-third of the recommended daily allowance of energy was offered every school day for 1 month, targeting 68 fourth-grade elementary schoolchildren. At baseline, the prevalence of anemia was 33.3%. The prevalence of stunting and underweight were 32.4% and 2.9%, respectively, whereas that of overweight and obesity combined was 17.6%, indicating a double burden of malnutrition among the subjects. During the intervention, intakes of protein ( p < 0.05), calcium ( p < 0.05), and vitamin C ( p < 0.001) significantly increased, while that of fat significantly decreased ( p < 0.001). After the intervention, hemoglobin ( p < 0.05) and hematocrit ( p < 0.05) levels were significantly improved, thereby almost halving the rate of anemia. These changes were significantly larger in the baseline anemic group than the non-anemic group ( p < 0.01). BMI significantly increased in the baseline underweight/normal group ( p < 0.001) but not in the overweight/obese group. The school lunch intervention significantly improved nutritional intakes and health statuses, implying its potential for reducing anemia and resolving the double burden of malnutrition among rural Indonesian schoolchildren.

    This study examined the hypothesis that a medical school in a low-resource setting, based on volunteer faculty, can be sustainable and associated with improvement in medical workforce and population health outcomes. Using a retrospective case study approach, this study described the formation of the Ateneo de Zamboanga University School of Medicine (ADZU SOM) in Zamboanga province, Mindanao, Philippines. The principal outcome measures were the number of graduated students practicing as physicians in the Philippines, the number of local municipalities with doctors, and changes in the provincial infant mortality rate since the School's inception. Since the first 15 graduates in 1999, by 2011 more than 160 students had successfully graduated with over 80% practicing in the local underserved regions. This compares with a national average of 68% of Philippine medical graduates practicing overseas. There has been a 55% increase (n=20 to 31) in the number of municipalities in Zamboanga with a doctor. Since the ADZU SOM's inception in 1994, the infant mortality rate in the region has decreased by approximately 90%, compared with a national change of approximately 50% in the same time period. The School has only three employees because all teachers continue to work as volunteer clinicians from the local health services. These results can encourage governments and communities around the world to consider adopting a socially accountable approach to medical education as a cost-effective strategy to improve medical workforce in underserved areas.

  1. Sustainability Infused Curriculum

    2015-12-01

    The Independent Schools Foundation Academy (ISF) in Hong Kong established a sustainability policy in 2015, which explicitly states, "an experimentally integrated, environmentally and ethically sustainable system of science education and conservation practices based on the 2012 Jeju Declaration of the World Conservation Congress will be implemented through the school". ISF Academy is a private Chinese bilingual school in Hong Kong serving over 1500 students K-12, following the framework and curriculum of the International Baccalaureate Organization (IBO). The strategy behind the implementation of this policy includes: development of a scientific sustainable curriculum that is age appropriate; establish a culture of sustainability within the ISF community and beyond to the wider HK community; install sustainable infrastructure that allows students to learn; and learn first hand sustainable living practices. It is well understood that solutions to the environmental challenges facing Hong Kong and our planet will require multiple disciplines. The current sustainability programs at ISF include: a) a whole school aerobic food waste composting system and organic farming, b) energy consumption monitoring of existing buildings, c) upcoming installation of an air pollution monitoring equipment that will correlate with the AQHI data collected by the Hong Kong government, d) a Renewable Energy Education Center (REEC) that will teach students about RE and also produce solar energy for classroom consumption, and e) student lead environmental group that manages the paper and used cooking oil recycling on campus. The Shuyuan Science and Sustainability faculty work closely with classroom teachers to ensure that the above mentioned projects are incorporated into the curriculum throughout the school. Interdisciplinary units (IDU) of study are being developed that encourage faculty and students to work across subject areas. Projects include Personal Projects, Extended Essays

    2015-03-01

    Full Text Available Whereas cross-sectional research has shown that transformational leadership, task interdependence, and self-efficacy are positively related to teachers’ engagement in reflective learning activities, the causal direction of these relations needs further inquiry. At the same time, individual teacher learning might play a mutual role in strengthening school-level capacity for sustained improvement. Building on previous research, this longitudinal study therefore examines how transformational leadership, task interdependence, self-efficacy, and teachers’ engagement in self-reflection mutually affect each other over time. Questionnaire data gathered on three measurement occasions from 655 Dutch Vocational Education and Training teachers was analyzed using a multivariate Latent Difference Score model. Results indicate that self-reflection and task interdependence reciprocally influence each other’s change. A considerate and stimulating transformational leader was found to contribute to this process. Change in self-efficacy was influenced by self-reflection, indicating that learning leads to competency beliefs. Together, the findings point to the important role transformational leadership practices play in facilitating teamwork, and sustaining teachers’ levels of learning in schools.

    Full Text Available The purpose of this paper is to describe the most relevant features of the Global Citizenship Education (GCE proposed by UNESCO for the Post-2015 Sustainable Development Agenda. Thus, after having submitted an educational, political, and epistemological proposal in Rio+20 to achieve a sustainable development for eradication of poverty, our research will be focused in the construc-tion of new philosophical discussions about the complexity of global problems of humanity in the third millennium. They include poverty, sustainable development, climate change, water scarcity, economic globalization, governance, ethics, health etc. Based on Complex Theory and transdici-plinary methodology, we also propose a transnational and transcultural educational milestone with the intentionality to contextualize human condition in the cosmodernity paradigm, which re-quires looking into the future with a polylogical perspective opened to universal interconnection and complexity of the world-society. Then, we propose the creation of a Constellation of Twinned NGOs-Schools which develop altruistic educational projects of cooperation in all corners of the planet to build, ultimately, a new transdemocratic horizon in the Cyber-Space-Time.

    Full Text Available Anaemia in school aged girls is an important but neglected issue. Since iron supplementation programmes have had little reported success in reducing anaemia, interest is turning to food based approaches that have higher potential for achieving far reaching benefits. The purpose of the study was to observe sustainability of the effect of iron and food supplementation on haemoglobin (Hb, intelligence quotient (IQ and growth of the subjects. At baseline, estimation of haemoglobin (Hb, red cell indices, serum iron, total iron binding capacity, serum transferrin saturation and serum ferritin was done. IQ, weight and height were measured using standard procedures. Anaemic subjectswere divided into three groups, viz., (i twice weekly supplementation of iron folic acid syrup (53 mg iron/week; (ii daily supplementation of 4 niger seed and defatted soyaflour biscuits plus 2 lemons (45 mg iron/week and (iii control. Non anaemic group(NAC was not intervened. Endline data was collected after 120 days. Follow up for Hb, IQ, weight and height was done 4 months after cessation of supplementation. The prevalence of anaemia was 77% in the study population; 46% subjects had mild anaemia and 32% had moderate anaemia. Iron status was lower in anaemic subjects (p<0.001.Iron supplementation was more effective in raising Hb and building iron stores than iron rich food supplementation. Iron supplementation improved IQ but did not bring about catch up of anaemics to non anaemics. Iron rich food supplementation was better than medicinal iron in promoting growth in anaemic girls. The impact of iron rich food supplementation on Hb, IQ and growth sustained for 4 months while that of medicinal iron did not. Effects of food supplementation are sustainable for 4 months, therefore, this strategy holds more potential to control anaemia, in school aged girls.

  5. The Potential of Non-Formal Laboratory Environments for Innovating the Chemistry Curriculum and Promoting Secondary School Level Students Education for Sustainability

    2015-02-01

    Full Text Available Developing skills and attitudes among students in terms of Education for Sustainable Development (ESD requires that educators address issues of sustainability in both formal and non-formal education. However, up to now, ESD seems to have been insufficiently implemented in secondary science education in many countries in general, and in high school chemistry learning in particular. A lack of suitable experiments, coupled with missing teaching and learning materials and insufficient teacher professional development have been identified as the reasons for this gap. This paper describes a project of innovation and research in the field of ESD for secondary school chemistry education. Within the project, both half- and full-day learning environments have been developed for non-formal, laboratory-based learning of secondary level students at the university. The research-based development focuses on teaching-learning modules which link formal and non-formal learning. The pedagogy employed is both learner-centered and inquiry-based. All the modules focus on sustainability issues in chemistry-related contexts. Data was collected by questionnaires from teachers and students both prior to and after the visit of the non-formal learning environment. Likert-items were analyzed statistically and the evaluation of the open-ended questions was done by Qualitative Content Analysis. An overview of the project, a case from the non-formal laboratory setting, and findings from accompanying research and evaluation are discussed in this paper. Potential impacts on teacher professional development and curriculum innovation are also outlined.

  10. On the transition to sustainability: an analysis of the costs of school feeding compared with the costs of primary education.

    2011-09-01

    The current food, fuel, and financial crises have highlighted the importance of school feeding programs both as a social safety net for children living in poverty and food insecurity, and as part of national educational policies and plans. To examine the costs of school feeding, in terms of both the absolute cost per child and the cost per child relative to overall education expenditure and gross domestic product (GDP) in low-, middle-, and high-income countries. Data on the costs of school feeding in different countries were collected from multiple sources, including World Food Programme project data, reports from government ministries, and, where such searches failed, newspaper articles and other literature obtained from internet searches. Regression models were then used to analyze the relationships between school feeding costs, the per capita costs of primary education and GDP per capita. School feeding programs in low-income countries exhibit large variations in cost, with concomitant opportunities for cost containment. As countries get richer, however, school feeding costs become a much smaller proportion of the investment in education. The per capita costs of feeding relative to education decline nonlinearly with increasing GDP. These analyses suggest that the main reason for this decline in the relative cost of school feeding versus primary education is a greatly increased investment per child in primary education as GDP rises, but a fairly flat investment in food. The analyses also show that there appears to be a transitional discontinuity at the interface between the lower- and middle-income countries, which tends to coincide with changes in the capacity of governments to take over the management and funding of programs. Further analysis is required to define these relationships, but an initial conclusion is that supporting countries to maintain an investment in school feeding through this transition may emerge as a key role for development partners.

    Equipping young people with the skills to participate successfully in increasingly complex environments and societies is a central issue of policy makers around the world. Only the understanding of complex socio-environmental systems establishes a basis for making decisions leading to sustainable development. However, OECD Pisa studies indicated, that only a low percentage of 15-year-old students was able to solve straightforward problems. Additionally, students get less interested in natural science education. In Austria "Sparkling Science" projects funded by the Federal Ministry of Science, Research and Economy in Austria target at integrating science with school learning by involving young people into scientific research for the purpose of developing new and engaging forms of interactive, meaningful learning. Within the Sparkling Science Project "Traisen.w3" scientists work together with 15 to 18-year-old students of an Austrian Secondary School over two years to identify and evaluate ecosystem services within the catchment of the river Traisen. One of the aims of the project is to foster system understanding of the youths by multi-modal school activities. To support the development of causal systems thinking, students developed qualitative causal models on processes in the catchment of the river Traisen with an interactive, hierarchically structured learning environment that was developed within the EU-FP7 project "DynaLearn" (http://www.dynalearn.eu) based on qualitative reasoning. Students worked in small groups and were encouraged to interlink entities, processes and simulate the results of the proposed interactions of hydrological, biological, ecological, spatial and societal elements. Within this setting collaborative problem solving competency through sharing knowledge, understanding and different perspectives was developed. Additionally, in several school workshops the ecosystem services concept was used as communication tool to show the

    Children with congenital hypothyroidism (CH) are at risk of developing mild cognitive impairment despite normal overall intellectual performance. These deficits may be caused by disease-related and treatment-related factors. This study explores the impact of abnormal thyroid function during the first 3 years of life on attention performance at school age. We included 49 children diagnosed with CH and receiving treatment for the condition: 14 boys (mean age 9.5±2.8 years) and 35 girls (9.6±2.6 years). The number of episodes of normal, under-, and overtreatment were estimated based on TSH levels during their first 3 years of life (at 12, 18, 24, 30, and 36 months). Children were assessed using a computerised version of a Sustained attention test. General linear models were calculated with the attention index as the dependent variable and sex, aetiology, and number of episodes of normal, under-, and overtreatment as independent variables. Higher numbers of episodes of overtreatment (low TSH level) were associated with poorer attention performance at school age (P=.005, r=-0.45). Children with CH should be monitored closely during the first 3 years of life in order to prevent not only hypothyroidism but also any adverse effects of overtreatment that may affect attentional function at school age.

    Enhancement of mental health literacy for youth is a focus of increasing interest for mental health professionals and educators alike. Schools are an ideal site for addressing mental health literacy in young people. Currently, there is limited evidence regarding the impact of curriculum-based interventions within high school settings. We examined the effect of a high-school mental health curriculum (The Guide) in enhancing mental health literacy in Canadian schools. We conducted a secondary analysis on surveys of students who participated in a classroom mental health course taught by their usual teachers. Evaluation of students' mental health literacy (knowledge/attitudes) was completed before and after classroom implementation and at 2-month follow-up. We used paired-samples t-tests and Cohen's d value to determine the significance and impact of change. There were 265 students who completed all surveys. Students' knowledge significantly improved between pre- and post-tests (p mental health. This is the first study to demonstrate the positive impact of a curriculum-based mental health literacy program in a Canadian high school population.

  18. Promoting children's sustainable access to early schooling in Africa: reflections on the roles of parents in their children's early childhood care and education.

    2014-01-01

    Sub-Saharan Africa has predominantly rural populations unable to offer children sustainable access to early literacy and childhood care and education. Children's literacy development starts very early in life through participation and experiences in the home and preschool. My research in rural Zimbabwe, Kenya, Uganda, and Tanzania shows that the transition from home to school is compromised by acute barriers such as lack of parental participation, lack of encouragement and support from teachers, and unavailability of learning materials. However, rural homes and communities are well endowed with a stock of practices, knowledge, and skills relevant to the promotion of literacy development. In this chapter, I reflect on how to empower parents to draw on knowledge and resources within the local context to become better involved in their children's education while also empowering teachers to better recognize and take advantage of local knowledge and resources to enrich instruction and enhance meaningful learning. © 2014 Wiley Periodicals, Inc.

    Ag2FeSiS4, Li2FeSnS4, and Li2FeGeS4 have been studied by first-principles calculations within density functional theory (DFT) added to the Coulomb energy (U Hubbard term) to treat the strong correlation of Fe 3d electrons. All three materials have shown that their conduction band minimum (CBM) and valence band maximum (VBM) were situated at Γ point, indicating a direct band gap of 1.99 and 2.26 eV, 2.24 eV for Ag2FeSiS4, Li2FeSnS4, and Li2FeGeS4 respectively. The lower part of the valence band was dominated by S-s orbitals while the mid part were contributed mostly by Sn/Ge-s and Ag-d states. Hence, the VBM and CBM were mainly due to Fe-d states. The bonding characterization have shown a strong covalent bonding between the Fe-S, Ge-S, Sn-S, Ag-S and Si-S atoms. The imaginary part of the dielectric constant have revealed that the first optical critical point energy occurred at 1.2 eV for Ag2FeSiS4, and at 2.0 eV for Li2FeSnS4, and Li2FeGeS4 compounds leading them to absorb less of visible spectrum. The existence of iron in the composition of these compounds have induced magnetic properties that we explored by the calculation of the magnetic moment and spin-densities maps.

    Hierarchical NiCo2 S4 nanotube@NiCo2 S4 nanosheet arrays on Ni foam have been successfully synthesized. Owing to the unique hierarchical structure, enhanced capacitive performance can be attained. A specific capacitance up to 4.38 F cm(-2) is attained at 5 mA cm(-2) , which is much higher than the specific capacitance values of NiCo2 O4 nanosheet arrays, NiCo2 S4 nanosheet arrays and NiCo2 S4 nanotube arrays on Ni foam. The hierarchical NiCo2 S4 nanostructure shows superior cycling stability; after 5000 cycles, the specific capacitance still maintains 3.5 F cm(-2) . In addition, through the morphology and crystal structure measurement after cycling stability test, it is found that the NiCo2 S4 electroactive materials are gradually corroded; however, the NiCo2 S4 phase can still be well-maintained. Our results show that hierarchical NiCo2 S4 nanostructures are suitable electroactive materials for high performance supercapacitors. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Advocates believed that to slow an expanding HIV/ AIDS epidemic in Washington, D.C., a local effort could ensure that HIV prevention was brought to scale. Schools were chosen as the focus and a new coalition advocated for the city government to pass new academic standards for health education. HIV and sex education policies had not been revised in more than 12 years and HIV education in D.C. public schools varied greatly in quality. Metro TeenAIDS (MTA), a traditional social service organization with no real history of advocacy work, reached only 10% of D.C. adolescents with critical HIV/AIDS prevention information. Clearly, to make a sustained impact, system change was necessary. After deciding to pursue a campaign focused on updating health education policy and creating standards, MTA convened a variety of reproductive health, adolescent medicine, and other organizations to establish the DC Healthy Youth Coalition. The Coalition used three complementary strategies to achieve campaign goals: mobilizing grassroots community support, involving parents in the discussion, and educating city leaders. By building an alliance of social service organizations and influencing critical public policy, the coalition ensured that new educational standards were passed.

    Chau Cuica was the name given by the regional government of Loreto in Peru for its school-based deworming program which was initiated in 2012 with a donation of mebendazole from an international non-governmental organization. Embedded in the program from the start was a sentinel surveillance component which consisted of 16 sentinel schools representing Loreto's seven provinces. Coverage rates varied between 35% and 61% over the first two years of the program (and seven deworming cycles). Initial prevalences of soil-transmitted helminth infections were high, with 82.4% of schoolchildren having at least one infection and prevalences of both Ascaris lumbricoides and Trichuris trichiura infections both exceeding 60%. After two years, these prevalences had dropped to 56% for any STH infection, 38% for A. lumbricoides and 34% for T. trichiura. Importantly, the proportions of children with moderate and heavy infections also dropped. Both the regional Ministry of Health and the Ministry of Education were jointly charged to implement this deworming program. The program's costs were estimated to be approximately 22 cents (USD) per child per deworming cycle. The responsibility for the surveillance component was initially undertaken by research partners from a local NGO and a Canadian university, which transferred gradually over the course of the deworming program to being entirely the responsibility of the Ministry of Health. This regional deworming program may serve as a model for other jurisdictions that are planning a school-based deworming program with an integrated surveillance component to monitor impact.

    Full Text Available This study provides a detailed description of the environmental education of elementary school students in Da Nang city, Vietnam. In January 2014, the study surveyed 247 students in two elementary schools. An evaluation of the students' knowledge of solid waste management was conducted. Students had basic knowledge about the environment, but their knowledge was limited with regard to solid waste management. In February 2015, an environmental education workshop was conducted for the students. The result showed that 96% of the students were interested in solid waste management activities. In addition, the study found that there were changes in the students' knowledge before and after environmental education activities. Before the activity 29% of the students said that they knew about eco-bags, and 55% of the students said that they knew “that plastic bags are difficult to decompose naturally.” After environmental education 87% of the students answered that they knew about eco-bags, and 71% of the students said that they knew “that plastic bags are difficult to decompose naturally.” Given these results, this study was successful in increasing students' knowledge about solid waste management.

    (2S,4R)- and (2S,4S)-perfluoro-tert-butyl 4-hydroxyproline were synthesized (as Fmoc-, Boc-, and free amino acids) in 2-5 steps. The key step of each synthesis was a Mitsunobu reaction with perfluoro-tert-butanol, which incorporated a perfluoro-tert-butyl group, with nine chemically equivalent fluorines. Both amino acids were incorporated in model α-helical and polyproline helix peptides. Each amino acid exhibited distinct conformational preferences, with (2S,4R)-perfluoro-tert-butyl 4-hydroxyproline promoting polyproline helix. Peptides containing these amino acids were sensitively detected by (19)F NMR, suggesting their use in probes and medicinal chemistry.

    Duffy, Erin E; Simon, Matthew D

    2016-12-07

    Metabolic labeling of cellular RNA is a useful approach to study RNA biology. 4-Thiouridine (s4 U) is a convenient nucleoside for metabolic labeling because it is cell permeable and is incorporated into newly transcribed RNA, and the sulfur moiety provides a handle for biochemical purification. However, a critical step in the purification of s4 U-RNA is the efficiency of the chemistry used to enrich s4 U-RNA. Here, we present a protocol for s4 U-RNA enrichment that includes efficient and reversible covalent chemistry to biotinylate s4 U-RNA using the activated disulfide methane thiosulfonate conjugated to biotin (MTS-biotin), followed by enrichment on streptavidin beads. The efficiency of this chemistry reduces enrichment bias and requires less starting material, thereby expanding the utility of s4 U to study RNA biology. © 2016 by John Wiley & Sons, Inc.

    2017-11-01

    We consider pure SU(2) Yang-Mills theory on four-dimensional de Sitter dS4 and anti-de Sitter AdS4 spaces and construct various solutions to the Yang-Mills equations. On de Sitter space we reduce the Yang-Mills equations via an SU(2)-equivariant ansatz to Newtonian mechanics of a particle moving in R^3 under the influence of a quartic potential. Then we describe magnetic and electric-magnetic solutions, both Abelian and non-Abelian, all having finite energy and finite action. A similar reduction on anti-de Sitter space also yields Yang-Mills solutions with finite energy and action. We propose a lower bound for the action on both backgrounds. Employing another metric on AdS4, the SU(2) Yang-Mills equations are reduced to an analytic continuation of the above particle mechanics from R^3 to R^{2,1} . We discuss analytical solutions to these equations, which produce infinite-action configurations. After a Euclidean continuation of dS4 and AdS4 we also present self-dual (instanton-type) Yang-Mills solutions on these backgrounds.

    KCu7S4 has the channel structure and minor resistance. Its double larger channels ensure that the ions can well exchange with other's, at the same time, can shorten the ionic diffusion path and improve the ionic and electronic transport. So KCu7S4 shows good electrochemical property. The paper reports a novel and high performance supercapacitor based on hybrid carbon particles and KCu7S4 (C/KCu7S4) electrode. For the hybrid structure with different proportions of C and KCu7S4, the C/KCu7S4 (1:10) hybrid supercapacitor shows preferable electrochemical performance and large specific capacitance (469 mF cm-2) at high charge-discharge rate (2 mA), still retaining ∼95% of the capacitance over 5000 cycles by charge-discharge process at a fixed current of 10 mA. Three supercapacitor units in series can light 50 light-emitting diodes (LEDs) for 2.5 min, 10 LEDs for 4 min, one LED for 5.5 min. The much-increased capacity, rate capability, and cycling stability may be attributed to the superionic conductive KCu7S4 nanowires and C/KCu7S4 hybrid structure, which improve ionic and electronic transport, enhance the kinetics of redox reactions through the electrode system.

The aim of this work, based on a literature review, is to highlight current sustainability perspectives and the related main issues. There is a broad consensus that the challenge to achieve a greater spread of sustainable practices is to enhance environmental and social sustainability while maintaining economic viability. From the producers' point of view, the priority is to bridge the still substantial knowledge gaps in terms of perceived environmental benefits, economic benefits, and costs. Thus, an increased research effort focusing on the costs and benefits of different winegrowing practices and technical assistance with implementation might support their diffusion. Moreover, targeted marketing strategies are needed to: enhance consumers' involvement and their attitude toward sustainable wine; improve understanding and use of sustainable labels and claims; and raise awareness of some environmental credentials of wine packaging, mainly with reference to lightweight glass bottles.

    The spinel-type compounds MYb2S4 ( M= Mg, Mn) have been prepared and magnetic susceptibility measurements have been carried out. Two types of sample for MnYb 2S 4 were obtained. The stable phase has a normal-spinel structure and the newly found metastable phase has a modified spinel structure which is not the inverse spinel. Susceptibility data show clearly the difference between both samples of MnYb 2S 4, which reflects the difference of the crystal field on Yb 3+ ions. Moreover, the magnitude of the FC susceptibility data for each type of MnYb 2S 4 is slightly larger than that of ZFC below about 50 K, while such difference is not observed for MgYb 2S 4.

    The promotion of dietary health is a public health priority in England and in other countries. Research shows that the majority of children do not consume the recommended amount of fruit and vegetables (F&V). There has been relatively little research on the impact of programmes, such as Food for Life, that (a) integrate action on nutrition and food sustainability issues, and (b) are delivered as commissions in a local authority area. The study sought to assess pupil F&V in schools engaged with the Food for Life (FFL) programme. The design was a cross-sectional study comparing pupils in FFL engaged (n = 24) and non-engaged (n = 23) schools. A total of 2411 pupils aged 8–10 completed a validated self-report questionnaire. After adjusting for confounders, pupils in schools engaged with FFL consumed significantly more servings of F&V compared to pupils in comparison schools (M = 2.03/1.54, p schools were twice as likely to eat five or more portions of F&V per day (Odds Ratio = 2.07, p schools with a higher level FFL award. Whilst limitations include possible residual confounding, the study suggests primary school engagement with the FFL programme may be an effective way of improving children’s dietary health.

    2017-08-08

    High surface area macroporous chalcogenide aerogels (chalcogels) MAu2GeS4 (M = Co, Ni) were prepared from K2Au2GeS4 precursor and Co(OAc)2 or NiCl2 by one-pot sol-gel metathesis reactions in aqueous media. The MAu2GeS4-chalcogels were screened for catalytic intramolecular hydroamination of 4-pentyn-1-amine substrate at different temperatures. 87% and 58% conversion was achieved at 100 °C, using CoAu2GeS4- and NiAu2GeS4-chalcogels respectively, and the reaction kinetics follows the first order. It was established that the catalytic performance of the aerogels is associated with the M(2+) centers present in the structure. Intermolecular hydroamination of aniline with 1-R-4-ethynylbenzene (R = -H, -OCH3, -Br, -F) was carried out at 100 °C using CoAu2GeS4-chalcogel catalyst, due to its promising catalytic performance. The CoAu2GeS4-chalcogel regioselectively converted the pair of substrates to respective Markovnikov products, (E)-1-(4-R-phenyl)-N-phenylethan-1-imine, with 38% to 60% conversion.

  6. Valence and core-level binding energy shifts in realgar (As 4S 4) and pararealgar (As 4S 4) arsenic sulfides

    The core level and valence band X-ray photoelectron spectra (XP spectra) of two arsenic sulfides, As 4S 4 (α-realgar) and As 4S 4 (pararealgar), are reported. Pararealgar is a polymorph of realgar created by irradiation of realgar with visible light. The core level spectra of the materials can be distinguished by small differences in core level binding energies (BEs). For example, the As 3d 5/2 and S 2p 3/2 peaks are at 43.1 and 162.8 eV BE, respectively, in realgar and 43.2 and 162.7 eV BE, respectively, in pararealgar. Density functional theory (DFT) calculations at the B3LYP/cc-pVDZ level were performed on single As 4S 4 clusters to determine the ground state orbital energies for realgar and pararealgar and electrostatic potential-derived atomic charges. The shifts in the core level BEs are qualitatively reproduced in the orbital energies and can be rationalized based on an increased average charge in pararealgar (S=-0.21, As=+0.21) versus realgar (S=-0.19, As=+0.19). A large variation in calculated charge between inequivalent As sites in pararealgar (from +0.09 to +0.31) broadens the observed arsenic XP spectra features. In addition, the four main features in the valence bands of these materials have been identified based on the DFT calculations.

    Corrections of order α(s)(4) for the axial singlet contributions for the decay rate of the Z boson into hadrons are evaluated in the limit of the heavy top quark mass. Combined with recently finished O(α(s)(4)) calculations of the nonsinglet corrections, the new results directly lead us to the first complete O(α(s)(4)) prediction for the total hadronic decay rate of the Z boson. The new O(α(s)(4)) term in Z-decay rate leads to a significant stabilization of the perturbative series, to a reduction of the theory uncertainty in the strong coupling constant α(s), as extracted from these measurements, and to a small shift of the central value.

    1996-10-01

    Tetra-arsenic tetrasulfide polymorphs have been investigated by IR, Raman and UV-visible spectroscopies. The mineral realgar ( α-As 4S 4) and the high-temperature phase β-As 4S 4 transform to pararealgar by exposure to monochromatic laser light with a reaction rate depending on the wavelength of the exciting radiation. The photoinduced alteration process has been monitored by Raman spectroscopy, following in real time the spectral changes of the samples undergoing irradiation. A satisfactory assignment of realgar, β-As 4S 4 and pararealgar was obtained by employing a simplified valence force field which provided a complete set of normal coordinates suitable for describing the vibrational spectra of these As 4S 4 polymorphs.

  10. Horizontal gene transfer of zinc and non-zinc forms of bacterial ribosomal protein S4

    Directory of Open Access Journals (Sweden)

    Luthey-Schulten Zaida

    2009-07-01

    Full Text Available Abstract Background The universal ribosomal protein S4 is essential for the initiation of small subunit ribosomal assembly and translational accuracy. Being part of the information processing machinery of the cell, the gene for S4 is generally thought of as being inherited vertically and has been used in concatenated gene phylogenies. Here we report the evolution of ribosomal protein S4 in relation to a broad sharing of zinc/non-zinc forms of the gene and study the scope of horizontal gene transfer (HGT of S4 during bacterial evolution. Results In this study we present the complex evolutionary history of ribosomal protein S4 using 660 bacterial genomes from 16 major bacterial phyla. According to conserved characteristics in the sequences, S4 can be classified into C+ (zinc-binding and C- (zinc-free variants, with 26 genomes (mainly from the class Clostridia containing genes for both. A maximum likelihood phylogenetic tree of the S4 sequences was incongruent with the standard bacterial phylogeny, indicating a departure from strict vertical inheritance. Further analysis using the genome content near the S4 genes, which are usually located in a conserved gene cluster, showed not only that HGT of the C- gene had occurred at various stages of bacterial evolution, but also that both the C- and C+ genes were present before the individual phyla diverged. To explain the latter, we theorize that a gene pool existed early in bacterial evolution from which bacteria could sample S4 gene variants, according to environmental conditions. The distribution of the C+/- variants for seven other zinc-binding ribosomal proteins in these 660 bacterial genomes is consistent with that seen for S4 and may shed light on the evolutionary pressures involved. Conclusion The complex history presented for "core" protein S4 suggests the existence of a gene pool before the emergence of bacterial lineages and reflects the pervasive nature of HGT in subsequent bacterial evolution

    2014-01-01

    The aim of this systematic review was to determine whether typically developing children and adolescents (aged 3-18 years) who have participated in school-based interventions have sustained outcomes in PA, fitness, and/or FMS. A systematic search of six electronic databases (CINAHL® Plus with Full Text, Ovid MEDLINE®, SPORTDiscus™, Scopus, PsycINFO® and ERIC) was conducted from 1995 to 26 July 2012. Included studies were school-based studies (including randomized controlled trials, longitudinal cohort, quasi-experimental, and experimental) that had a positive effect at post intervention in at least one variable and had a follow-up PA, fitness, or FMS assessment at least 6 months after the post-intervention assessment. Risk of bias assessment was guided by the "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" statement. The search identified 14 articles, and some studies addressed multiple outcomes: 13 articles assessed PA; three assessed fitness; and two assessed FMS. No study in this review met four key methodological criteria that have been shown to influence results, i.e., clarity on the randomization process, assessor blinding, analyzing participants in their original groups, and retaining sufficient participants through the entire study. Three-quarters (ten of 13) of the studies addressing PA, reported PA behavior change maintenance. The length of follow-up ranged from 6 months to 20 years, and the degree of PA difference reported was between 3 and 14 min per day. Only one of the three studies assessing fitness reported a sustained impact, whilst both studies that assessed FMS reported maintenance of effects. It is likely that PA is a sustainable outcome from interventions in children and adolescents, and there is reasonable evidence that interventions of longer than 1 year and interventions that utilize a theoretical model or framework are effective in producing this sustained impact. It would seem probable that FMS are a sustainable

    2015-04-01

    Atomic-deficient free volume structure of realgar α-As4S4, the low-temperature modification, of tetraarsenic tetrasulfide polymorphs, is studied using positron annihilation lifetime spectroscopy. Eventual channels of positron annihilation in this molecular crystal are shown to be connected with low electron density entities around cage As4S4 molecules composing realgar-type structure of monoclinic P21/n space group. The overlapped spaces of bond-free solid angles around S atoms forming self-closed As4S4 molecules contribute preferentially to positron trapping modes, while a competitive influence of bound positron-electron states (positronium) stabilized in intermolecular spaces occurs also to be essential in the decomposed lifetime spectra too.

    KCNQ1 plays important roles in the cardiac action potential and consists of an N-terminal domain, a voltage-sensor domain, a pore domain and a C-terminal domain. KCNQ1 is a voltage-gated potassium channel and its channel activity is regulated by membrane potentials. The linker between transmembrane helices 4 and 5 (S4-S5 linker) is important for transferring the conformational changes from the voltage-sensor domain to the pore domain. In this study, the structure of the S4-S5 linker of KCNQ1 was investigated by solution NMR, circular dichroism and fluorescence spectroscopic studies. The S4-S5 linker adopted a helical structure in detergent micelles. The W248 may interact with the cell membrane. Copyright © 2014 Elsevier Inc. All rights reserved.

  11. SUSTAINABLE TRANSPORTATION

    Directory of Open Access Journals (Sweden)

    Linda STEG

    2007-01-01

    Full Text Available This paper discusses possible contributions of psychologists to sustainable transportation. It is argued that in order to reach sustainable transportation, among others, behaviour changes of individual car users are needed. As transport policies will be more effective if they target important antecedents of travel behaviour, first, factors influencing such behaviour are discussed. It is argued that car use is very attractive and sometimes even necessary for many different reasons. This implies that a combination of policies is called for, each targeting different factors that support car use and hinder the use of more sustainable modes of transport. Next, the paper elaborates on policy strategies that may be employed to achieve sustainable transportation by changing car use. Increasing the attractiveness of sustainable transport modes by means of pull measures seems not sufficient to reduce the level of car use. Besides, car use should be made less attractive by means of push measures to force drivers to reconsider their travel behaviour. The acceptability of such policies may be increased by clearly communicating the aim of these policies, and the expected positive consequences (e.g., less congestion, improved environmental quality. Moreover, possible negative effects for individual freedom may be compensated by implementing additional policies aimed at facilitating the use of sustainable transport modes.

    Cations and anions are replaced with Fe, Mn, and Se in CZTS in order to control the formations of the secondary phase, the band gap, and the micro structure of Cu2ZnSnS4. We demonstrate a simplified synthesis strategy for a range of quaternary chalcogenide nanoparticles such as Cu2ZnSnS4 (CZTS), Cu2FeSnS4 (CFTS), Cu2MnSnS4 (CMTS), Cu2ZnSnSe4 (CZTSe), and Cu2ZnSn(S0.5Se0.5)4 (CZTSSe) by thermolysis of metal chloride precursors using long chain amine molecules. It is observed that the crystal structure, band gap and micro structure of the CZTS thin films are affected by the substitution of anion/cations. Moreover, secondary phases are not observed and grain sizes are enhanced significantly with selenium doping (grain size ~1 μm). The earth-abundant Cu2MSnS4/Se4 (M = Zn, Mn and Fe) nanoparticles have band gaps in the range of 1.04–1.51 eV with high optical-absorption coefficients (~104 cm−1) in the visible region. The power conversion efficiency of a CZTS solar cell is enhanced significantly, from 0.4% to 7.4% with selenium doping, within an active area of 1.1 ± 0.1 cm2. The observed changes in the device performance parameters might be ascribed to the variation of optical band gap and microstructure of the thin films. The performance of the device is at par with sputtered fabricated films, at similar scales. PMID:27748406

    The willingness of public authority to delegate social and environmental regulation to the private sector has varied from sector to sector, but has often led to the establishment of ‘voluntary’ standards and certifications on sustainability. Many of these have taken the form of ‘stewardship...... councils’ and ‘sustainability roundtables’ and have been designed around a set of institutional features seeking to establish legitimacy, fend off possible criticism, and ‘sell’ certifications to potential users. The concept of ‘roundtabling’ emphasizes the fitting a variety of commodity......-specific sustainability situations into a form that not only ‘hears more voices’ (as in ‘multi-stakeholder’), but also portrays to give them equal standing at the table of negotiations (roundtable), thus raising higher expectations on accountability, transparency and inclusiveness. In this article, I examine to what...

    The long-term substitution of fossil resources can only be achieved through a bio-based economy, with biorefineries and bio-based products playing a major role. However, it is important to assess the implications of the transition to a bio-based economy. Life cycle-based sustainability assessment is probably the most suitable approach to quantify impacts and to identify trade-offs at multiple levels. The extended utilisation of biomass can cause land use change and affect food security of the most vulnerable people throughout the world. Although this is mainly a political issue and governments should be responsible, the responsibility is shifted to companies producing biofuels and other bio-based products. Organic wastes and lignocellulosic biomass are considered to be the preferred feedstock for the production of bio-based products. However, it is unlikely that a bio-based economy can rely only on organic wastes and lignocellulosic biomass.It is crucial to identify potential problems related to socio-economic and environmental issues. Currently there are many approaches to the sustainability of bio-based products, both quantitative and qualitative. However, results of different calculation methods are not necessarily comparable and can cause confusion among decision-makers, stakeholders and the public.Hence, a harmonised, globally agreed approach would be the best solution to secure sustainable biomass/biofuels/bio-based chemicals production and trade, and to avoid indirect effects (e.g. indirect land use change). However, there is still a long way to go.Generally, the selection of suitable indicators that serve the purpose of sustainability assessment is very context-specific. Therefore, it is recommended to use a flexible and modular approach that can be adapted to various purposes. A conceptual model for the selection of sustainability indicators is provided that facilitates identifying suitable sustainability indicators based on relevance and significance in a

  1. Exergy sustainability.

    Energy Technology Data Exchange (ETDEWEB)

    Robinett, Rush D. III (.; ); Wilson, David Gerald; Reed, Alfred W.

    2006-05-01

    Exergy is the elixir of life. Exergy is that portion of energy available to do work. Elixir is defined as a substance held capable of prolonging life indefinitely, which implies sustainability of life. In terms of mathematics and engineering, exergy sustainability is defined as the continuous compensation of irreversible entropy production in an open system with an impedance and capacity-matched persistent exergy source. Irreversible and nonequilibrium thermodynamic concepts are combined with self-organizing systems theories as well as nonlinear control and stability analyses to explain this definition. In particular, this paper provides a missing link in the analysis of self-organizing systems: a tie between irreversible thermodynamics and Hamiltonian systems. As a result of this work, the concept of ''on the edge of chaos'' is formulated as a set of necessary and sufficient conditions for stability and performance of sustainable systems. This interplay between exergy rate and irreversible entropy production rate can be described as Yin and Yang control: the dialectic synthesis of opposing power flows. In addition, exergy is shown to be a fundamental driver and necessary input for sustainable systems, since exergy input in the form of power is a single point of failure for self-organizing, adaptable systems.

    2017-09-01

    The ambient temperature structure of Cu4SnS4 has been revisited and the recently reported low temperature structure has been confirmed from single-crystal X-ray diffraction data. A structural phase transition from a large monoclinic unit cell at low temperature to a smaller orthorhombic unit cell at high temperature has been observed. The room temperature phase exhibited disorder in the two copper sites, which is a different finding from earlier reports. The low temperature monoclinic form crystallizes in P21/c space group, which is isostructural with Cu4GeS4. The phase transition has also been studied with variable temperature powder X-ray diffraction and 119Sn Mössbauer spectroscopy. The Seebeck coefficients and electrical resistivity of polycrystalline Cu4SnS4 are reported from 16 to 400 K on hot pressed pellets. Thermal conductivity measurements at high temperatures, 350 - 750 K exhibited very low thermal conductivities in the range 0.28 - 0.35 W K-1 m-1. In all the transport measurements the phase transition has been observed at around 232 K. Resistivity decreases, while Seebeck coefficient increases after the phase transition during warming up from low to high temperatures. This change in resistivity has been correlated with the results of first-principles electronic band structure calculations using highly-accurate screened-exchange local density approximation. It was found that both the low hole effective mass of 0.63 me for the Γ→Y crystallographic direction and small band gap, 0.49 eV, are likely to contribute to the observed higher conductivity of the orthorhombic phase. Cu4SnS4 is also electrochemically active and shows reversible reaction with lithium between 1.7 and 3.5 volts.

  9. Double gaps along Shaker S4 demonstrate omega currents at three different closed states.

    Gamal El-Din, Tamer M; Heldstab, Hansjakob; Lehmann, Claudia; Greeff, Nikolaus G

    2010-01-01

    The aim of the present study was to investigate in detail how the voltage sensor in the Shaker potassium channel moves during the gating process. After the publication of the open channel structure from the crystallized K(V)AP channel in 2003, an alternative so-called "paddle" model was put forward in contrast to the existing helical screw model. The voltage sensor S4 contains 4 arginine residues relevant for gating, R1(362), R2(365), R3(368) and R4(371), each separated by 2 neutral residues. These charged residues coil as one of three threads on the S4-alpha-helix. Based on a previous finding that the mutation R1S leads to the so-called omega leak current through a "gating-pore" in the closed state, we introduced gaps systematically along the arginine thread substituting long arginines by short serines. Mutations R2S or R3S did neither create transient nor steady leaks. The fact that the native residue A359, which is located three amino acids in front of R1, is a short one, motivated us to check its role. Mutation of A359 to arginine blocked the omega current in the R1S mutant indicating that the omega pore is occupied by A359 and R1. Introducing further double gaps (RR to SS) at sequential positions (0 + 1, 1 + 2, 2 + 3), produced clear leak currents which were remarkably stable over a wide voltage range. These leaks contradict that S4 would swing together with S3 in lipid according to the paddle hypothesis. Rather, our results show that during gating the S4 segment moves in 3 helical steps through a fixed pore formed by the channel protein.

    2013-12-01

    The quaternary chalcogenide crystal Cu2CdGeS4 was studied both experimentally and theoretically in the present paper. Investigations of polarized fundamental absorption spectra demonstrated a high sensitivity to external light illumination. The photoinduced changes were studied using a cw 532 nm green laser with energy density about 0.4 J cm-2. The spectral maximum of the photoinduced anisotropy was observed at spectral energies equal to about 1.4 eV (energy gap equal to about 1.85 eV) corresponding to maximal density of the intrinsic defect levels. Spectroscopic measurements were performed for polarized and unpolarized photoinducing laser light to separate the contribution of the intrinsic defect states from that of the pure states of the valence and conduction bands. To understand the origin of the observed photoinduced absorption near the fundamental edge, the benchmark first-principles calculations of the structural, electronic, optical and elastic properties of Cu2CdGeS4 were performed by the general gradient approximation (GGA) and local density approximation (LDA) methods. The calculated dielectric function and optical absorption spectra exhibit some anisotropic behavior (shift of the absorption maxima in different polarizations) within the 0.15-0.20 eV energy range not only near the absorption edge; optical anisotropy was also found for the deeper inter-band transition spectral range. Peculiar features of chemical bonds in Cu2CdGeS4 were revealed by studying the electron density distribution. Possible intrinsic defects are shown to affect the optical absorption spectra considerably. Pressure effects on the structural and electronic properties were modeled by optimizing the crystal structure and calculating all relevant properties at elevated hydrostatic pressure. The first estimations of the bulk modulus (69 GPa (GGA) or 91 GPa (LDA)) and its pressure derivative for Cu2CdGeS4 are also reported.

    2017-12-01

    Solid-state sodium electrolytes are expected to improve next-generation batteries on the basis of favorable energy density and reduced cost. Na3SbS4 represents a new solid-state ion conductor with high ionic conductivities in the mS/cm range. Here, we explore the tetragonal phase of Na3SbS4 and its interface with metallic sodium anode using a combination of experiments and first-principles calculations. The computed Na-ion vacancy migration energies of 0.1 eV are smaller than the value inferred from experiment, suggesting that grain boundaries or other factors dominate the experimental systems. Analysis of symmetric cells of the electrolyte—Na/Na 3SbS4/Na —show that a conductive solid electrolyte interphase forms. Computer simulations infer that the interface is likely to be related to Na3SbS3 , involving the conversion of the tetrahedral SbS43 - ions of the bulk electrolyte into trigonal pyramidal SbS33 - ions at the interface.

Studies conducted by UNCTAD shows that corporate phenomenon developments in the world economy is growing. Without claiming to present an exhaustive topic so vast we tried to capture some "facets" of sustainable development from the perspective of multinational corporations, given the expansion of these economic entities and strengthening their power in the global economy. We present more negative aspects of the actions of multinational corporations in terms of sustainable development, it is very important to know both sides of the coin, which will not only help transnational giants including release. Based on issues such as corporate social responsibility, environmental pollution and workers' rights, we sought to counter official statements. The conclusion is that these economic entities are real forces that can not be ignored in today's world and the obvious problem of sustainable development can not be addressed independently of the phenomenon, context we also identified some possible solutions to conflict of corporations and essence of the concept of sustainable development.

    Secondary school students in Spain commonly show little knowledge on the way science is produced and diffused. To familiarize students with the scientific method and scientific communication, we have simulated a scientific congress on Earth Sciences at the secondary school level. Since 2002, the congress takes place yearly and it is attended by teachers and students from high schools of our hometown and beyond. Since its onset, the project follows several phases: (i) In the first phase (First Call), 14- to 18-year-old students are invited to register by means of brochures containing basic information on the congress (terms, conditions and main topics). (ii) Teachers from each participating school explain students the basis of scientific posters and oral presentations and encourage them to participate in the congress. (iii) Students prepare presentations describing the results of small scientific experiments carried out for this purpose and present them to the local organizing committee. (iv) The committee then reviews all presentations and select the best ones for public exposition. (v) In the final phase, the congress takes place. It includes registration, opening ceremony attended by educational authorities, plenary conference delivered by an outstanding local scientist, coffee break, oral presentations and closing ceremony. The project lasts for one day. It has been attended by an average of 250 students and teachers from 4 schools, and has been widely reported in the local media. Post-congress evaluation shows that the project is highly motivating for students and it improves student knowledge on scientific research and communication.

    Changes in gene expression, metabolism, and energy requirements are hallmarks of cancer growth and self-sufficiency. Upregulation of the PI3K/Akt/mTor pathway in tumor cells has been shown to stimulate aerobic glycolysis, which has enabled (18)F-FDG PET tumor imaging. However, of the millions of (18)F-FDG PET scans conducted per year, a significant number of malignant tumors are (18)F-FDG PET-negative. Recent studies suggest that several tumors may use glutamine as the key nutrient for survival. As an alternative metabolic tracer for tumors, (18)F-(2S,4R)4-fluoroglutamine was developed as a PET tracer for mapping glutaminolytic tumors. A series of in vitro cell uptake and in vivo animal studies were performed to demonstrate tumor cell addiction to glutamine. Cell uptake studies of this tracer were performed in SF188 and 9L glioblastoma tumor cells. Dynamic small-animal PET studies of (18)F-(2S,4R)4-fluoroglutamine were conducted in 2 animal models: xenografts produced in F344 rats by subcutaneous injection of 9L tumor cells and transgenic mice with M/tomND spontaneous mammary gland tumors. In vitro studies showed that both transformed 9L and SF188 tumor cells displayed a high rate of glutamine uptake (maximum uptake, ≈ 16% dose/100 μg of protein). The cell uptake of (18)F-(2S,4R)4-fluoroglutamine by SF188 cells is comparable to that of (3)H-L-glutamine but higher than that of (18)F-FDG. The tumor cell uptake can be selectively blocked. Biodistribution and PET studies showed that (18)F-(2S,4R)4-fluoroglutamine localized in tumors with a higher uptake than in surrounding muscle and liver tissues. Data suggest that certain tumor cells may use glutamine for energy production. The results support that (18)F-(2S,4R)4-fluoroglutamine is selectively taken up and trapped by tumor cells. It may be useful as a novel metabolic tracer for tumor imaging.

    Sensory and/or motor function sparing, including the S4-S5 spinal cord segment, is central to classifying neurologic impairment after spinal cord injury (SCI) using the American Spinal Injury Association Impairment Scale (AIS) grades within the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI). Within the ISNCSCI protocol, which is essential for both clinical and research purposes, assessing sacral sparing requires an anorectal and S4-S5 examination. However, in situations where these data are incomplete, the relationships between anorectal/S4-S5 examinations and functional preservation at more rostral sacral segments may be useful. To evaluate whether slightly more rostral sensory and motor outcomes of the ISNCSCI can accurately predict caudal sacral sparing (S4-S5 dermatome sensation, "deep pressure" anal sensation [AS], and voluntary anal contraction [AC]). Retrospective analysis of the European Multicenter Study about Spinal Cord Injury database. One thousand four hundred sixty-seven AIS-A, AIS-B, and AIS-C subjects. International Standards for Neurological Classification of Spinal Cord Injury examinations. The value of six factors (sensory preservation at S1, S2, and S3; motor preservation at S1; motor function at more than three segments below the motor level; and sensory function at more than three segments below the neurologic level) for predicting ISNCSCI sacral sparing measures (AS, S4-S5 dermatome sensation, AC) was evaluated. Combinations of the most promising factors were then evaluated for their ability to accurately predict the AIS grade. Preserved sensation at the first sacral segment (S1S) provided good prediction (90.5%) of caudal sacral sensory sparing (ie, AS or S4-S5 sensation). Voluntary anal contraction was accurately predicted by preserved motor function within the first sacral segment (S1M) in 85.4% of cases. The alternate classification schemes evaluated for accurately predicting the AIS classification

First, various trends in consumption are outlined to highlight some of the challenges for sustainability transitions. Then, it is discussed how consumption...... patterns are shaped over time and what should be considered in sustainability strategies. While discussions on consumption often take their point of departure in the perspective of the individual and then zoom to the wider context, the present approach is the opposite. The outline starts with the basic...... biophysical, distributional and economic conditions for high consumption in rich countries and then zooms in on the coevolution of provision systems and consumption, and how consumption is shaped by practices and projects in everyday life. Furthermore, the paper discusses whether and how transition...

    2015-01-01

    This study compared the effects of 6 and 12 sessions of relaxation training on emotional distress, short-term memory, and sustained attention in primary school children. Participants (N = 132) aged 10 and 11 years old participated in this study. All participants and their parents provided written informed consent. Participants completed the measurement instruments before and after the completion of relaxation training. Nearly half (49%) of all respondents reported moderate to extremely severe stress, and 80 and 61% reported moderate to extremely severe anxiety and depression, respectively. The results of a one-way analysis of variance revealed a significant difference among the groups in mean changes in short-term memory. A greater memory increase was observed in the 12-session than in the six-session and no-training group. It can be conceived that 12-session of training should be considered when prescribing relaxation regimens as a nonspecific clinical treatment (i.e. for healthy students).

    2015-01-01

    The objective of this study was to investigate the association of different cognitive abilities with children's body weight adjusted for further weight influencing sociodemographic, family, and lifestyle factors. Cross-sectional data of 498 primary school children (7.0 ± 0.6 years; 49.8% boys) participating in a health promotion programme in southwest Germany were used. Children performed a computer-based test battery (KiTAP) including an inhibitory control task (Go-Nogo paradigm), a cognitive flexibility task, and a sustained attention task. Height and weight were measured in a standardized manner and converted to BMI percentiles based on national standards. Sociodemographic features (migration background and parental education), family characteristics (parental body weight), and children's lifestyle (TV consumption, physical activity, consumption of sugar-sweetened beverages and breakfast habits) were assessed via parental questionnaire. A hierarchical regression analysis revealed inhibitory control and cognitive flexibility to be significant cognitive predictors for children's body weight. There was no association concerning sustained attention. The findings suggest that especially cognitive abilities known as executive functions (inhibitory control and cognitive flexibility) are associated with children's body weight. Future longitudinal and intervention studies are necessary to investigate the directionality of the association and the potential of integrating cognitive training in obesity prevention strategies. This trial is registered with ClinicalTrials.gov DRKS00000494.

Compliance was already present in previous EU public procurement frameworks, but its extent on Directive 2014/24/EU leads the authors to consider the current legal framework...... as subject to substantial regulatory compliance obligations external to the process of procurement. In short, procurement has been transformed in a way to enforce regulatory obligations that are not intrinsic to the process of buying. This leads to the conclusion that questions such as the cost and trade...

    The splitter/merger section of the CBETA project [1] consists of 4 beam lines as shown in Fig. 1. Two of the functions of the splitter’s/merger’s lines is to match the beam parameters at the exit of the Energy Recovery Linac (ERL) to the beam parameters at the entrance of the Fixed Field Alternating Gradient (FFAG) arc, and also place the reference particles of the beam bunches at the entrance of the FFAG arc on specified trajectories according to their energies. In this technical note we are presenting results from the 2D and 3D electromagnetic analysis of the S4.BEN01 magnet which is one of the dipole magnets of the 150 MeV line of the splitter/merger. In particular we present results from two designs of the S4.BEN01 magnet, one based on iron dominated current-excited magnet, and the other design based on Halbach-type permanent magnet. An evaluation of the two designs will be given in the section under “conclusion”.

    Full Text Available Nanocrystalline Cu2ZnSnS4 (CZTS powder was synthesized by a hydrothermal process, using thiourea as sulfur precursor. The powder was qualitatively analyzed using X-ray to identify the phase, and the size of the particles was determined using transmission electron microscopy (TEM. Raman peak at 337.5 cm−1 confirms the formation of pure CZTS particles. The powder was also synthesized solvothermally using ethylenediamine as solvent. The hydrothermally synthesized powder indicated the presence of the kesterite phase Cu2ZnSnS4 and particle size of about 4-5 nm. This environmentally green synthesis by hydrothermal route can produce gram scale synthesis of material with a chemical yield in excess of ~ 90%. UV Vis absorption spectra measurements indicated the band gap of as-synthesized CZTS nanoparticles to be 1.7 eV, which is near the optimum value for photovoltaic solar cell, showing its possible use in photovoltaics.

    Transient receptor potential (TRP) channels are cation channels which participate in a wide variety of physiological processes in organisms ranging from fungi to humans. They fulfill roles in body homeostasis, are sensors for noxious chemicals and temperature in the mammalian somatosensory system and are activated by light stimulated phospholipase C activity in Drosophila or by hypertonicity in yeast. The transmembrane topology of TRP channels is similar to that of voltage-gated cation channels. TRP proteins assemble as tetramers with each subunit containing six transmembrane helices (S1-S6) and intracellular N- and C-termini. Here we focus on the emerging functions of the cytosolic S4-S5 linker on TRP channel gating. Most of this knowledge comes from pathogenic mutations within the S4-S5 linker that alter TRP channel activities. This knowledge has stimulated forward genetic approaches to identify additional residues around this region which are essential for channel gating and is supported, in part, by recent structures obtained for TRPV1, TRPV2, TRPV6, TRPA1, and TRPP2.

    Excessive recreational screen time (i.e., screen use for entertainment) is a global public health issue associated with adverse mental and physical health outcomes. Considering the growing popularity of screen-based recreation in adolescents, there is a need to identify effective strategies for reducing screen time among adolescents. The aim of this paper is to report the rationale and study protocol for the 'Switch-off 4 Healthy Minds' (S4HM) study, an intervention designed to reduce recreational screen time among adolescents. The S4HM intervention will be evaluated using a cluster randomized controlled trial in eight secondary schools (N=322 students) in New South Wales, Australia. The 6-month multi-component intervention will encourage adolescents to manage their recreational screen time using a range of evidence-based strategies. The intervention is grounded in Self-Determination Theory (SDT) and includes the following components: an interactive seminar for students, eHealth messaging, behavioral contract and parental newsletters. All outcomes will be assessed at baseline and at 6-months (i.e., immediate post-test). The primary outcome is recreational screen time measured by the Adolescent Sedentary Activity Questionnaire (ASAQ). Secondary outcomes include: self-reported psychological well-being, psychological distress, global physical self-concept, resilience, pathological video gaming and aggression, and objectively measured physical activity (accelerometry) and body mass index (BMI). Hypothesized mediators of behavior change will also be explored. The S4HM study will involve the evaluation of an innovative, theory-driven, multi-component intervention that targets students and their parents and is designed to reduce recreational screen time in adolescents. The intervention has been designed for scalability and dissemination across Australian secondary schools. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available In four ways, massively multiplayer online role-playing games may serve as tools for advancing sustainability goals, and as laboratories for developing alternatives to current social arrangements that have implications for the natural environment. First, by moving conspicuous consumption and other usually costly status competitions into virtual environments, these virtual worlds might reduce the need for physical resources. Second, they provide training that could prepare individuals to be teleworkers, and develop or demonstrate methods for using information technology to replace much transportation technology, notably in commuting. Third, virtual worlds and online games build international cooperation, even blending national cultures, thereby inching us toward not only the world consciousness needed for international agreements about the environment, but also toward non-spatial government that cuts across archaic nationalisms. Finally, realizing the potential social benefits of this new technology may urge us to reconsider a number of traditional societal institutions.

An untapped yet promising pool of willing participants are capable high school students that have a strong STEM interest but may lack the skills and the guided mentoring needed to succeed in competitive STEM fields. This study evaluates and compares the impact of the Loma Linda University (LLU Summer Health Disparities Research Program on high school (HS and undergraduate (UG student participants. The primary focus of our summer research experience (SRE is to enhance the research self-efficacy of the participants by actively involving them in a research project and by providing the students with personalized mentoring and targeted career development activities, including education on health disparities. The results of our study show that our SRE influenced terminal degree intent and increased participant willingness to incorporate research into future careers for both the HS and the UG groups. The quantitative data shows that both the HS and the UG participants reported large, statistically significant gains in self-assessed research skills and research self-efficacy. Both participant groups identified the hands-on research and the mentor experience as the most valuable aspects of our SRE and reported increased science skills, increased confidence in science ability and increased motivation and affirmation to pursue a science career. The follow-up data indicates that 67% of the HS participants and 90% of the UG participants graduated from college with a STEM degree; for those who enrolled in graduate education, 61% and 43% enrolled in LLU, respectively. We conclude that structured SREs can be highly effective STEM strengthening interventions for both UG and HS students and may be a way to measurably increase institutional and biomedical

The follow-up data indicates that 67% of the HS participants and 90% of the UG participants graduated from college with a STEM degree; for those who enrolled in graduate education, 61% and 43% enrolled in LLU, respectively. We conclude that structured SREs can be highly effective STEM strengthening interventions for both UG and HS students and may be a way to measurably increase institutional and biomedical workforce

    An urgent need exists for graduate and professional schools to establish evidence-based STEM (science, technology, engineering, and math) pipeline programs to increase the diversity of the biomedical workforce. An untapped yet promising pool of willing participants are capable high school students that have a strong STEM interest but may lack the skills and the guided mentoring needed to succeed in competitive STEM fields. This study evaluates and compares the impact of the Loma Linda University (LLU) Summer Health Disparities Research Program on high school (HS) and undergraduate (UG) student participants. The primary focus of our summer research experience (SRE) is to enhance the research self-efficacy of the participants by actively involving them in a research project and by providing the students with personalized mentoring and targeted career development activities, including education on health disparities. The results of our study show that our SRE influenced terminal degree intent and increased participant willingness to incorporate research into future careers for both the HS and the UG groups. The quantitative data shows that both the HS and the UG participants reported large, statistically significant gains in self-assessed research skills and research self-efficacy. Both participant groups identified the hands-on research and the mentor experience as the most valuable aspects of our SRE and reported increased science skills, increased confidence in science ability and increased motivation and affirmation to pursue a science career.

  14. Holographic microstate counting for AdS4 black holes in massive IIA supergravity

    2017-10-01

    We derive the Bekenstein-Hawking entropy for a class of BPS black holes in the massive type IIA supergravity background AdS4 × S 6 from a microscopic counting of supersymmetric ground states in a holographically dual field theory. The counting is performed by evaluating the topologically twisted index of three-dimensional N=2 Chern-Simons-matter gauge theories in the large N limit. The I-extremization principle is shown to match the attractor mechanism for the near-horizon geometries constructed in the four-dimensional dyonic N=2 gauged supergravity, that arises as a consistent truncation of massive type IIA supergravity on S 6. In particular, our results prove that the imaginary part of the three-dimensional partition functions plays a crucial rôle in holography.

    Tse, Kin Fai; Wong, Manhoi; Zhang, Yiou; Zhang, Jingzhao; Zhu, Junyi

    The thermodynamics of Na and K incorporation and its effects in Cu2ZnSnS4 (CZTS) is studied using density functional theory with hybrid functional. The allowed chemical potential of Na/K in CZTS is established. Formation energy calculations shows that Na can be significantly incorporated as both substitutional defects and interstitial defects, and incorporation of K related defects are generally less favorable. Transition energy calculations is performed showing that both Na and K exhibit benign defect properties and act as a p-type dopant. The qualitative disagreement between GGA with rigid band edge shifting and HSE calculations, formation of defect complexes, and implications in experiment will also be discussed. The understandings on the defect properties of Na and K provides an essential knowledge to further understand the surfactant effects of Na and K observed in experiments.

    2017-12-01

    We consider a class of models of neutrino mixing with S 4 lepton flavour symmetry combined with a generalised CP symmetry, which are broken to residual Z 2 and Z 2 × H CP ν symmetries in the charged lepton and neutrino sectors, respectively, H CP ν being a remnant CP symmetry of the neutrino Majorana mass term. In this set-up the neutrino mixing angles and CP violation (CPV) phases of the neutrino mixing matrix depend on three real parameters — two angles and a phase. We classify all phenomenologically viable mixing patterns and derive predictions for the Dirac and Majorana CPV phases. Further, we use the results obtained on the neutrino mixing angles and leptonic CPV phases to derive predictions for the effective Majorana mass in neutrinoless double beta decay.

    In the search for a new material for solar cells, the quaternary chalcogenide copper zinc tin sulde (Cu2ZnSnS4 or CZTS) is one potential candidate. It is abundant, environmentally-friendly, inexpensive, and presently it has a mediocre record effciency of around 10% with potential to reach above 15......%. This thesis is a part of the work done in making the prospects of solutionprocessed CZTS more fruitful. In addition to an inexpensive material, a cheap production pathway is also required for the material to be suitable for solar cells of the future. Solution-processing comprises either a nanoparticle ink...... or a precursor ink that can be printed, sprayed, or in another way coated on a substrate appropriate for mass production. For CZTS, the power conversion effciency of these device are lagging behind the vacuum processed CZTS thin films, as certain challenges arise with solution-processing. The conversion...

    The CMB Stage 4 (CMB-S4) experiment is a next-generation, ground-based experiment that will measure the cosmic microwave background (CMB) polarization to unprecedented accuracy, probing the signature of inflation, the nature of cosmic neutrinos, relativistic thermal relics in the early universe, and the evolution of the universe. CMB-S4 will consist of O(500,000) photon-noise-limited detectors that cover a wide range of angular scales in order to probe the cosmological signatures from both the early and late universe. It will measure a wide range of microwave frequencies to cleanly separate the CMB signals from galactic and extra-galactic foregrounds. To advance the progress towards designing the instrument for CMB-S4, we have established a framework to optimize the instrumental configuration to maximize its scientific output. The framework combines cost and instrumental models with a cosmology forecasting tool, and evaluates the scientific sensitivity as a function of various instrumental parameters. The cost model also allows us to perform the analysis under a fixed-cost constraint, optimizing for the scientific output of the experiment given finite resources. In this paper, we report our first results from this framework, using simplified instrumental and cost models. We have primarily studied two classes of instrumental configurations: arrays of large-aperture telescopes with diameters ranging from 2–10 m, and hybrid arrays that combine small-aperture telescopes (0.5-m diameter) with large-aperture telescopes. We explore performance as a function of telescope aperture size, distribution of the detectors into different microwave frequencies, survey strategy and survey area, low-frequency noise performance, and balance between small and large aperture telescopes for hybrid configurations. Both types of configurations must cover both large (~ degree) and small (~ arcmin) angular scales, and the performance depends on assumptions for performance vs. angular scale

    A series of ZnInxS4+y (x=1.6, 2.0, 2.3, 2.6, 2.9, 3.1) photocatalysts were synthesized via a facile hydrothermal method and characterized by various analytical techniques, such as XRD, EDS, UV-vis DRS, SEM, TEM, BET and PL. The ZnInxS4+y photocatalysts had a similar crystal structure. With the increase of indium content, the absorption edges of ZnInxS4+y photocatalysts shifted to longer wavelength, their crystal sizes decreased firstly and then increased and the variation of the specific surface area and total pore volume was exactly opposite. Especially, when x=2.3, ZnIn2.3S4+y catalyst had smallest crystal size, largest specific surface area and total pore volume. Additionally, the morphology of ZnInxS4+y greatly depended on the contents of indium. The photocatalytic activity of ZnInxS4+y was evaluated by photocatalytic hydrogen production from water under visible light. The ZnIn2.3S4+y sample had the highest photocatalytic activity among these ZnInxS4+y photocatalysts and its hydrogen production rate was 363 μmol/g h.

  2. Sustainability Science Needs Sustainable Data!

    Sustainability science (SS) is an 'emerging field of research dealing with the interactions between natural and social systems, and with how those interactions affect the challenge of sustainability: meeting the needs of present and future generations while substantially reducing poverty and conserving the planet's life support systems' (Kates, 2011; Clark, 2007). Bettencourt & Kaur (2011) identified more than 20,000 scientific papers published on SS topics since the 1980s with more than 35,000 distinct authors. They estimated that the field is currently growing exponentially, with the number of authors doubling approximately every 8 years. These scholars are undoubtedly using and generating a vast quantity and variety of data and information for both SS research and applications. Unfortunately we know little about what data the SS community is actually using, and whether or not the data that SS scholars generate are being preserved for future use. Moreover, since much SS research is conducted by cross-disciplinary, multi-institutional teams, often scattered around the world, there could well be increased risks of data loss, reduced data quality, inadequate documentation, and poor long-term access and usability. Capabilities and processes therefore need to be established today to support continual, reliable, and efficient preservation of and access to SS data in the future, especially so that they can be reused in conjunction with future data and for new studies not conceived in the original data collection activities. Today's long-term data stewardship challenges include establishing sustainable data governance to facilitate continuing management, selecting data to ensure that limited resources are focused on high priority SS data holdings, securing sufficient rights to allow unforeseen uses, and preparing data to enable use by future communities whose specific research and information needs are not yet known.

  3. Cascading gauge theory on dS4 and String Theory landscape

    Placing anti-D3 branes at the tip of the conifold in Klebanov-Strassler geometry provides a generic way of constructing meta-stable de Sitter (dS) vacua in String Theory. A local geometry of such vacua exhibit gravitational solutions with a D3 charge measured at the tip opposite to the asymptotic charge. We discuss a restrictive set of such geometries, where anti-D3 branes are smeared at the tip. Such geometries represent holographic dual of cascading gauge theory in dS4 with or without chiral symmetry breaking. We find that in the phase with unbroken chiral symmetry the D3 charge at the tip is always positive. Furthermore, this charge is zero in the phase with spontaneously broken chiral symmetry. We show that the effective potential of the chirally symmetric phase is lower than that in the symmetry broken phase, i.e., there is no spontaneous chiral symmetry breaking for cascading gauge theory in dS4. The positivity of the D3 brane charge in smooth de-Sitter deformed conifold geometries with fluxes presents difficulties in uplifting AdS vacua to dS ones in String Theory via smeared anti-D3 branes. First, turning on fluxes on Calabi-Yau compactifications of type IIB string theory produces highly warped geometry with stabilized complex structure (but not Kähler) moduli of the compactification [3]; Next, including non-perturbative effects (which are under control given the unbroken supersymmetry), one obtains anti-de Sitter (AdS4) vacua with all moduli fixed; Finally, one uses anti-D3 branes of type IIB string theory to uplift AdS4 to de Sitter (dS4) vacua. As the last step of the construction completely breaks supersymmetry, it is much less controlled. In fact, in [4-7] it was argued that putting anti-D3 branes at the tip of the Klebanov-Strassler (KS) [8] geometry (as done in KKLT construction) leads to a naked singularity. Whether or not the resulting singularity is physical is subject to debates. When M4=dS4 and the chiral symmetry is unbroken, the D3 brane

    High-purity, well-crystallized spinel Fe3S4 nanoplatelets were synthesized by the hydrothermal method, and the saturation magnetic moment of Fe3S4 was measured at 1.83 μB/f.u. The temperature-dependent resistivity of Fe3S4 was metallic-like for T < 180 K: room-temperature resistivity was measured at 7.711 × 103  μΩ cm. The anomalous Hall conductivity of Fe3S4 decreased with increasing longitudinal conductivity, in sharp contrast with the accepted theory of the anomalous Hall effect in a dirty-metal regime. Furthermore, negligible spin-dependent magnetoresistance was observed. Band structure calculations confirmed our experimental observations that Fe3S4 is a metal and not a half metal as expected.

    Visible light active copper molybdenum sulfide (Cu2MoS4) nanosheets were successfully anchored on reduced graphene oxide (rGO) using facile hydrothermal method. During the hydrothermal reaction, reduction of graphene oxide into rGO and the formation of Cu2MoS4 nanosheets were successfully obtained. The charge transfer interaction between the rGO sheets and Cu2MoS4 nanosheets extended the absorption to visible region in comparison with bare Cu2MoS4 nanosheets i.e without rGO sheets. Furthermore, the notable photoluminescence quenching observed for Cu2MoS4/rGO nanocomposite revealed the effective role of rGO towards the significant inhibition of electron-hole pair recombination. The photocatalytic efficiencies of bare Cu2MoS4 and Cu2MoS4/rGO nanocomposite was evaluated for the degradation of methyl orange dye under visible irradiation (λ > 420 nm). A maximum photodegradation efficiency of 99% was achieved for Cu2MoS4/rGO nanocomposite, while only 64% photodegradation was noted for bare Cu2MoS4. The enhanced optical absorption in visible region, high surface area, and low charge carrier recombination in the presence of rGO sheets were the main reasons for the enhancement in photodegardation of MO dye. In addition, the resultant Cu2MoS4/rGO nanocomposite was found to be reusable for five successive cycles without significant loss in its photocatalytic performance.

    The growing environmental, industrial and commercial interests in understanding the processes of carbon dioxide (CO2) capture and conversion have led us to simulate, by means of density functional theory calculations, the application of different iron oxide and sulfide minerals to capture, activate and catalytically dissociate this molecule. We have chosen the {001} and {111} surfaces of the spinel-structured magnetite (Fe3O4) and its isostructural sulfide counterpart greigite (Fe3S4), which are both materials with the Fe cations in the 2+/3+ mixed valence state, as well as mackinawite (tetragonal FeS), in which all iron ions are in the ferrous oxidation state. This selection of iron-bearing compounds provides us with understanding of the effect of the composition, stoichiometry, structure and oxidation state on the catalytic activation of CO2 The largest adsorption energies are released for the interaction with the Fe3O4 surfaces, which also corresponds to the biggest conformational changes of the CO2 molecule. Our results suggest that the Fe3S4 surfaces are unable to activate the CO2 molecule, while a major charge transfer takes place on FeS{111}, effectively activating the CO2 molecule. The thermodynamic and kinetic profiles for the catalytic dissociation of CO2 into CO and O show that this process is feasible only on the FeS{111} surface. The findings reported here show that these minerals show promise for future CO2 capture and conversion technologies, ensuring a sustainable future for society.This article is part of a discussion meeting issue 'Providing sustainable catalytic solutions for a rapidly changing world'. © 2017 The Author(s).

    Full Text Available The Technology Innovation and Engineering Education (TIEE is a proposed Unit/Center/Department concept model inside a college of engineering. The TIEE concept has been developed in particular taking in consideration the Gulf Cooperation Council (GCC and/or Qatar contextual needs and National Vision in the transformation into a Knowledge Based Economy (KBE. The main purpose of such structure is to enable engineering colleges to better respond to these emerging needs of the GCC countries. In this paper, the concept of TIEE is provisioned as an abstract example of organizational structure development for other engineering education institutions that aim to play a key role in innovation and sustainable socio-economic development. The concept is derived from similar global examples and contextualized regionally; it is generic and can be deployed elsewhere with slight modifications. The TIEE concept is in particular vital for engineering institutions in the Middle East and North Africa as a vehicle for economic and technological development. The paper outlines the organizational structure of TIEE, together with its various programs and activities for implementing its stated vision, mission, and strategic objectives. Within this context, the paper also provides a thorough account on advances in engineering innovation, education, scholarship of engineering education, and developments of similar entities.

    Scientists are front and center in quantifying and solving environmental problems. Yet, as a spate of recent news articles in scientific journals point out, much can be done to enhance sustainability within the scientific enterprise itself, particularly by trimming the energy use associated with research facilities and the equipment therein (i,ii,iii, iv). Sponsors of research unwittingly spend on the order of $10 billion each year on energy in the U.S. alone, and the underlying inefficiencies drain funds from the research enterprise while causing 80 MT CO2-equivalent greenhouse-gas emissions (see Box). These are significant sums considering the opportunity costs in terms of the amount of additional research that could be funded and emissions that could be reduced if the underlying energy was used more efficiently. By following commercially proven best practices in facility design and operation, scientists--and the sponsors of science--can cost-effectively halve these costs, while doing their part to put society on alow-carbon diet.

  12. Investing in African research training institutions creates sustainable capacity for Africa: the case of the University of the Witwatersrand School of Public Health masters programme in epidemiology and biostatistics.

    Improving health in Africa is a high priority internationally. Inadequate research capacity to produce local, relevant research has been identified as a limitation to improved population health. Increasing attention is being paid to the higher education sector in Africa as a method of addressing this; evidence that such investment is having the desired impact is required. A 1998 3-year investment by the Special Programme for Research and Training in Tropical Diseases (TDR) in research training at the School of Public Health, University of the Witwatersrand, South Africa was reviewed to assess its' impact. A descriptive cross-sectional survey of the 70 students registered for the masters programme in epidemiology & biostatistics from 2000-2005 was conducted. Data were collected from self-administered questionnaires. Sixty percent (42/70) of students responded. At the time of the survey 19% of respondents changed their country of residence after completion of the masters course, 14% migrated within Africa and 5% migrated out of Africa. Approximately half (47%) were employed as researchers and 38% worked in research institutions. Sixty percent reported research output, and four graduates were pursuing PhD studies. Government subsidy to higher education institutions, investments of the University of the Witwatersrand in successful programmes and ongoing bursaries for students to cover tuition fees were important for sustainability. Investing in African institutions to improve research training capacity resulted in the retention of graduates in Africa in research positions and produced research output. Training programmes can be sustained when national governments invest in higher education and where that funding is judiciously applied. Challenges remain if funding for students bursaries is not available.

    Tineke W H Meijer

    Full Text Available BACKGROUND AND PURPOSE: Carbonic anhydrase IX (CAIX plays a pivotal role in pH homeostasis, which is essential for tumor cell survival. We examined the effect of the CAIX inhibitor 4-(3'(3",5"-dimethylphenyl-ureidophenyl sulfamate (S4 on the tumor microenvironment in a laryngeal tumor model by analyzing proliferation, apoptosis, necrosis, hypoxia, metabolism and CAIX ectodomain shedding. METHODS: SCCNij202 tumor bearing-mice were treated with S4 for 1, 3 or 5 days. CAIX ectodomain shedding was measured in the serum after therapy. Effects on tumor cell proliferation, apoptosis, necrosis, hypoxia (pimonidazole and CAIX were investigated with quantitative immunohistochemistry. Metabolic transporters and enzymes were quantified with qPCR. RESULTS: CAIX ectodomain shedding decreased after treatment with S4 (p<0.01. S4 therapy did neither influence tumor cell proliferation nor the amount of apoptosis and necrosis. Hypoxia (pimonidazole and CAIX expression were also not affected by S4. CHOP and MMP9 mRNA as a reference of intracellular pH did not change upon treatment with S4. Compensatory mechanisms of pH homeostasis at the mRNA level were not observed. CONCLUSION: As the clinical and biological meaning of the decrease in CAIX ectodomain shedding after S4 therapy is not clear, studies are required to elucidate whether the CAIX ectodomain has a paracrine or autocrine signaling function in cancer biology. S4 did not influence the amount of proliferation, apoptosis, necrosis and hypoxia. Therefore, it is unlikely that S4 can be used as single agent to influence tumor cell kill and proliferation, and to target primary tumor growth.

    We study the gauging of the orthosymplectic algebras OSp(6|4)xSO(2) and its "dual" OSp(2|4)x SO(6), both based on supergravities with the same exceptional coset SO*(12)/U(6), and gauge group SO(6)xSO(2). The two dual theories are obtained by two different truncations of gauged N=8 AdS_4 supergravity. We explicitly study the gauge sector of the two dual theories with the most general group allowed by supersymmetry. In the ungauged (super-Poincar\\'e) case they exhibit the same (large) black-hole attractor solutions with dual relations between the 1/N-BPS and non-BPS configurations. The N=6 gravity multiplet has also the exceptional property to be a {\\em zero-center module} of OSp(6|4), as it is the case for superconformal Yang--Mills theory in four dimensions based on SU(2,2|n) (PSU(2,2|4) for n=4) or OSp(n|4).

    We investigate in detail the m2=0 Abelian Higgs model in AdS4 , which is considered as the holographic dual of the most BCS-like superfluid. In homogeneous and isotropic superfluid solutions, we calculate the fourth-sound speeds, the square of which approaches 1 /2 with increasing chemical potential (lowering temperature). Then we present the single dark soliton solutions, which becomes thinner with increasing chemical potential. For the first time, we also find the interesting double and triple dark soliton solutions, which is unexpected and shows the possibility of more complicated static configurations. Finally, we investigate vortex solutions. For winding number n =1 , the vortex becomes thinner with increasing chemical potential. At a given chemical potential, with increasing winding number, first the vortex becomes bigger and the charge density depletion becomes larger, and then the charge density depletion settles down at a certain value and the growth of the vortex size is found to obey a scaling symmetry.

    A precursor powder was obtained from drying the solutions of a mixture of different ratios of Cu, Zn and Sn chloride and thiourea. The Cu2ZnSnS4 (CZTS) samples were prepared from thermal decomposition of the corresponding precursors in vacuum, and were then characterized using scanning emission microscopy, energy dispersive x-ray analysis, x-ray powder diffraction and Raman scattering. According to x-ray diffraction analysis, all the synthesized samples had a tetragonal structure of space group I\\overline{4} 2m. The electrical properties of the CZTS samples were investigated in the temperature range of 10-325 K. The charge carrier concentration was measured to be about p = 1 × 1016 cm-3. A crossover from a nearest-neighbor hopping conduction mechanism at high temperatures ( T > 150 K) to a Mott variable-range hopping conduction mechanism at low temperatures ( T quartz substrates was obtained using magnetron sputtering, for which a band gap of E g = 1.3 eV was determined from transmittance measurements.

    We report on neutron diffraction, thermal expansion, magnetostriction, dielectric, and specific heat measurements on polycrystalline FeCr2S4 in external magnetic fields. The ferrimagnetic ordering temperatures TC ≈ 170 K and the transition at TOO ≈ 10 K, which has been associated with orbital ordering, are only weakly shifted in magnetic fields up to 9 T. The cubic lattice parameter is found to decrease when entering the state below TOO. The magnetic moments of the Cr- and Fe-ions are reduced from the spin-only values throughout the magnetically ordered regime, but approach the spin-only values for fields >5.5 T. Thermal expansion in magnetic fields and magnetostriction experiments indicate a contraction of the sample below about 60 K. Below TOO this contraction is followed by a moderate expansion of the sample for fields larger than ~4.5 T. The transition at TOO is accompanied by an anomaly in the dielectric constant. The dielectric constant depends on both the strength and orientation of the external magnetic field with respect to the applied electric field for T magnetic-field-induced change of the dielectric constant and the magnetic-field dependent magnetization is observed. This behaviour is consistent with the existence of a ferroelectric polarization and a multiferroic ground state below 10 K. PMID:25123960

    Full Text Available The research in thin film solar cells has been dominated by light absorber materials based on CdTe and Cu(In,GaSe2 (CIGS in the last several decades. The concerns of environment impact of cadmium and the limited availability of indium in those materials have driven the research towards developing new substitute light absorbers made from earth abundant, environment benign materials. Cu2ZnSnS4 (CZTS semiconductor material has emerged as one of the most promising candidates for this aim and has attracted considerable interest recently. Significant progress in this relatively new research area has been achieved in the last three years. Over 130 papers on CZTS have been published since 2007, and the majority of them are on the preparation of CZTS thin films by different methods. This paper, will review the wide range of techniques that have been used to deposit CZTS semiconductor thin films. The performance of the thin film solar cells using the CZTS material will also be discussed.

    Post-translational modifications play a key role in defining the biological functions of proteins. Among them, the hydroxylation of proline producing the (2S,4R)-4-hydroxyproline (Hyp) is one of the most frequent modifications observed in vertebrates, being particularly abundant in the proteins of the extracellular matrix. In collagen, hydroxylation of proline plays a critical role, conferring the correct structure and mechanical strength to collagen fibers. In elastin, the exact role of this modification is not yet understood. Here we show that Hyp-containing elastin polypeptides have flexible molecular structures, analogously to proline-containing polypeptides. In turn, the self-assembly of the elastin peptides is significantly altered by the presence of Hyp, evidencing different supramolecular structures. Also the in vitro susceptibility to protease digestion is changed. These findings give a better insight into the elastic fiber formation and degradation processes in the extracellular matrix. Furthermore, our results could contribute in defining the subtle role of proline structural variants in the folding and self-assembly of elastin-inspired peptides, helping the rational design of elastin biomaterials.

    This paper describes the results of the synthesis and characterization of a quaternary semiconductor based on Cu2ZnTiS4 (abbreviated CZTiS), using a hydrothermal technique. The results confirm that time (24, 48 and 72 hours) and temperature (250, 275, and 300°C) factors, used in synthesis process, regulate different levels of electrical conductivity in these materials. The results of ultraviolet spectroscopy (UV) analysis, confirm the production of semiconductor solids with Band-gap values around 1.4eV, being coherent with a strong absorption in the ultraviolet region. The X-Ray Diffraction analysis (XRD), confirm that there is an opposite and proportional relationship between the crystal sizes, the reaction times and the synthesis temperature. In all cases, the particle sizes were 50-100nm. The results derived from Scanning Electron Microscopy (SEM), confirm the obtaining of homogenous materials with optimal morphological properties in accordance with synthesis method. Similarly, the composition values derived from the Energy-Dispersion X-ray Spectroscopy analysis (EDS), shown that obtained compositions are in agree with expected values. Finally, the results of electric characterization, confirm that used synthesis parameters show a strong dependence on the conductive behaviour of solids being the most relevant result the shown by the solid obtained at 300°C and 72 hours of reaction in accordance with preliminary works.

    On January 6, 2016 at 10:30am, the artificial earthquake in the DPRK was detected by multiple international seismic organizations. After 2 hours, the DPRK announced on state TV that 'The first H-bomb test was successfully conducted in the DPRK at 10:00 am on Wednesday, Juche 105(2016), pursuant to the strategic determination of the ruling communist party.' There has been a doubt about the real nature of the DPRK's 4th nuclear test, since 2 months have been passed after its nuclear test. To analyze the nature of the DPRK's nuclear test, it is necessary to check possible options for production of essential materials. The pathways to produce nuclear fusion material (tritium) and to have a relatively high possibility for the DPRK are described in this article. Tritium is key material for H-bomb. And there are two options for the DPRK which are 1) production and 2) illicit trafficking. And this study is focused on production possibility of DPRK. Determination of the nature of DPRK's nuclear test is very hard issue.

    2017-12-01

    We propose a Grand Unified Theory of Flavour, based on SO(10) together with a non-Abelian discrete group S 4, under which the unified three quark and lepton 16-plets are unified into a single triplet 3'. The model involves a further discrete group ℤ 4 R × ℤ 4 3 which controls the Higgs and flavon symmetry breaking sectors. The CSD2 flavon vacuum alignment is discussed, along with the GUT breaking potential and the doublet-triplet splitting, and proton decay is shown to be under control. The Yukawa matrices are derived in detail, from renormalisable diagrams, and neutrino masses emerge from the type I seesaw mechanism. A full numerical fit is performed with 15 input parameters generating 19 presently constrained observables, taking into account supersymmetry threshold corrections. The model predicts a normal neutrino mass ordering with a CP oscillation phase of 260°, an atmospheric angle in the first octant and neutrinoless double beta decay with m ββ = 11 meV. We discuss N 2 leptogenesis, which fixes the second right-handed neutrino mass to be M 2 ≃ 2 × 1011 GeV, in the natural range predicted by the model.

    The physical properties of ZnIn2S5 (n-type) crystals have been investigated experimentally in order to determine the possibility of using them as windows in the preparation of heterojunction solar cells with chalcopyrite compounds as p-type absorbers. The crystals have a high resistivity of between 0.8 and 10 ohms per cm and they were prepared by an annealing process under a high manganese pressure. Optical transmission spectra for the material were obtained for a sample 63 microns thick with a band gap of about 2.34 eV, and a heterojunction was formed by vacuum deposition of CuInSe2 onto ZnIn2S4. Prior to evaporation, the substrates were etched in a 3HCl: 1HNO3 solution and the thin films were deposited by flash evaporation techniques. An analysis of the spectral response of the material showed that it is possible to obtain crystals which are good enough to be used as windows in solar cells. It is recommended that the materials be used in the form of thin films with a resistivity of about 0.1 ohms/c.

    The energy-dispersive x-ray diffraction technique has been employed to study the structure and equation of state of realgar As4S4 under pressures up to 8 GPa at room temperature. We have obtained pressure dependences of the unit cell parameters and volume for the monoclinic structure of realgar. An approximation of the equation of state through the Murnaghan equation gives the bulk modulus and its derivative, B0 = 8.1 ± 0.5 GPa and B0' = 9.0 ± 0.5, respectively. A comparison of the obtained values with the corresponding values for other molecular crystals is drawn and discussed. At a pressure of around 7 GPa, realgar showed a polymorph transition to a new molecular phase with a supposedly orthorhombic structure. Such identification is evidenced by the presence of geometrical correlations between the parameters of the parent monoclinic phase and those of the new phase, and the phase transition is likely to be associated with the removal of a monoclinic distortion in the unit cell.

    A novel and facile one-step sonochemical method is used to synthesize Cu2ZnSnS4 (CZTS) nanoparticles (2.6 ± 0.4 nm) as cathode electrocatalyst for hydrogen evolution reactions. The detailed morphology, crystal and surface structure, and composition of the CZTS nanostructures were characterized by high resolution transmission electron microscopy (HR-TEM), Selected area electron diffraction (SAED), X-ray diffraction, Raman spectroscopy, FTIR analysis, Brunauer-Emmett-Teller (BET) surface area measurements, Electron dispersive analysis, X-ray photoelectron spectroscopy respectively. Electrocatalytic abilities of the nanoparticles toward Hydrogen Evolution Reactions (HER) were verified through cyclic voltammograms (CV) and Linear sweep voltammetry (LSV), electrochemical impedance spectroscopy (EIS), and Tafel polarization measurements. It reveals enhanced activity at lower onset potential 300 mV v/s RHE, achieved at exceptionally high current density -130 mA/cm2, which is higher than the existing non-nobel metal based cathodes. Further result exhibits Tafel slope of 85 mV/dec, exchange current density of 882 mA/cm2, excellent stability (> 500 cycles) and lower charge transfer resistance. This sonochemically fabricated CZTSs nanoparticles are leading to significantly reduce cell cost and simplification of preparation process over existing high efficiency Pt and other nobel metal-free cathode electrocatalyst.

    We explore a facile and nontoxic hydrothermal route for synthesis of a Cu2ZnSnS4 nanocrystalline material by using l-cysteine as the sulfur source and ethylenediaminetetraacetic acid (EDTA) as the complexing agent. The effects of the amount of EDTA, the mole ratio of the three metal ions, and the hydrothermal temperature and time on the phase composition of the obtained product have been systematically investigated. The addition of EDTA and an excessive dose of ZnCl2 in the hydrothermal reaction system favor the generation of kesterite Cu2ZnSnS4. Pure kesterite Cu2ZnSnS4 has been synthesized at 180°C for 12 h from the reaction system containing 2 mmol of EDTA at 2:2:1 of Cu/Zn/Sn. It is confirmed by Raman spectroscopy that those binary and ternary phases are absent in the kesterite Cu2ZnSnS4 product. The kesterite Cu2ZnSnS4 material synthesized by the hydrothermal process consists of flower-like particles with 250 to 400 nm in size. It is revealed that the flower-like particles are assembled from single-crystal Cu2ZnSnS4 nanoflakes with ca. 20 nm in size. The band gap of the Cu2ZnSnS4 nanocrystalline material is estimated to be 1.55 eV. The films fabricated from the hierarchical Cu2ZnSnS4 particles exhibit fast photocurrent responses under intermittent visible-light irradiation, implying that they show potentials for use in solar cells and photocatalysis.

    The deleterious effects of climate change mean that environmental sustainability is increasingly becoming a moral and economic necessity. Consequently, clinicians will increasingly be called upon to manage the effects of health care on climate change, and they must therefore do as much as is practically possible to limit the negative effects of their practice on the environment. As medical educators we have the opportunity not only to reduce the environmental impact of our own clinical practice, but also that of those who we teach, through innovation. Such novelty can be explored during student-selected components (SSCs). Clinicians will increasingly be called upon to manage effects of health care on climate change The project, entitled 'Can we introduce sustainability to clinical skills teaching?' was led by two third-year medical students during their SSC periods. New ways to make existing skills more sustainable were explored by surveying existing practice in the workplace, analysing selected skills in a lab-based setting and through discussions with sustainability champions. Cannulation and intravenous (IV) antibiotic preparation were chosen by the students as prototype skills. These skills were observed by the students in the workplace and adapted by them to appease the 'triple bottom line' of sustainability: environmental, social and economic factors were addressed. The revised skills were taught by the students to their peers in a sustainably conscious fashion. Provided that such innovations in sustainable skills teaching are deemed appropriate by clinical skills directors, such methods could be adopted across medical schools and expanded to cover a wider range of skills. © 2014 John Wiley & Sons Ltd.

  18. Gravitational wave memory in dS4+2n and 4D cosmology

    Science.gov (United States)

    Chu, Y.-Z.

    2017-02-01

    We argue that massless gravitons in all even dimensional de Sitter (dS) spacetimes higher than two admit a linear memory effect arising from their propagation inside the null cone. Assume that gravitational waves (GWs) are being generated by an isolated source, and over only a finite period of time {η\\text{i}}≤slant η ≤slant {η\\text{f}} . Outside of this time interval, suppose the shear-stress of the GW source becomes negligible relative to its energy-momentum and its mass quadrupole moments settle to static values. We then demonstrate, the transverse-traceless (TT) GW contribution to the perturbation of any dS4+2n written in a conformally flat form ({{a}2}{ημ ν}\\text{d}{{x}μ}\\text{d}{{x}ν} )—after the source has ceased and the primary GW train has passed—amounts to a spacetime constant shift in the flat metric proportional to the difference between the TT parts of the source’s final and initial mass quadrupole moments. As a byproduct, we present solutions to Einstein’s equations linearized about de Sitter backgrounds of all dimensions greater than three. We then point out there is a similar but approximate tail induced linear GW memory effect in 4D matter dominated universes. Our work here serves to improve upon and extend the 4D cosmological results of Chu (2015 Phys. Rev. D 92 124038), which in turn preceded complementary work by Bieri et al (2015 arXiv:1509.01296) and by Kehagias and Riotto (2016 arXiv:1602.02653).

    Using 3.6 and 4.5 μm images of 73 late-type, edge-on galaxies from the S4G survey, we compare the richness of the globular cluster populations of these galaxies to those of early-type galaxies that we measured previously. In general, the galaxies presented here fill in the distribution for galaxies with lower stellar mass, M*, specifically {log}({M}*/{M}⊙ )\\lt 10, overlap the results for early-type galaxies of similar masses, and, by doing so, strengthen the case for a dependence of the number of globular clusters per 109M⊙ of galaxy stellar mass, TN, on M*. For 8.5\\lt {log}({M}*/{M}⊙ )\\lt 10.5 we find the relationship can be satisfactorily described as {T}{{N}}={({M}*/{10}6.7)}-0.56 when M* is expressed in solar masses. The functional form of the relationship is only weakly constrained, and extrapolation outside this range is not advised. Our late-type galaxies, in contrast to our early types, do not show the tendency for low-mass galaxies to split into two TN families. Using these results and a galaxy stellar mass function from the literature, we calculate that, in a volume-limited, local universe sample, clusters are most likely to be found around fairly massive galaxies (M* ˜ 1010.8M⊙) and present a fitting function for the volume number density of clusters as a function of parent-galaxy stellar mass. We find no correlation between TN and large-scale environment, but we do find a tendency for galaxies of fixed M* to have larger TN if they have converted a larger proportion of their baryons into stars.

    The potential return of samples back to Earth in a future NASA mission would require protection of our planet from the risk of bringing uncontrolled biological materials back with the samples. In order to ensure this does not happen, it would be necessary to "break the chain of contact (BTC)", where any material reaching Earth would have to be inside a container that is sealed with extremely high confidence. Therefore, it would be necessary to contain the acquired samples and destroy any potential biological materials that may contaminate the external surface of their container while protecting the sample itself for further analysis. A novel synchronous separation, seaming, sealing and sterilization (S4) process for sample containerization and planetary protection has been conceived and demonstrated. A prototype double wall container with inner and outer shells and Earth clean interstitial space was used for this demonstration. In a potential future mission, the double wall container would be split into two halves and prepared on Earth, while the potential on-orbit execution would consist of inserting the sample into one of the halves and then mating to the other half and brazing. The use of brazing material that melts at temperatures higher than 500°C would assure sterilization of the exposed areas since all carbon bonds are broken at this temperature. The process would be executed in two-steps, Step-1: the double wall container halves would be fabricated and brazed on Earth; and Step-2: the containerization and sterilization process would be executed on-orbit. To prevent potential jamming during the process of mating the two halves of the double wall container and the extraction of the brazed inner container, a cone-within-cone approach has been conceived and demonstrated. The results of this study will be described and discussed.

    The electrodeposition mechanism of pure phase Cu2ZnSnS4 (CZTS) thin film with subsequent annealing was investigated in detail. An electrolyte design principle of quaternary compounds was proposed. The complex ions of Cu(H2C6H5O7)+, Cu2(C6H5O7)+, Zn(C4H5O6)+, Sn(H2C6H5O7)+ and Sn2(C6H5O7)+, which influenced the reduction process and played important roles in co-deposition, were identified by UV spectra. Electrochemical studies indicated that trisodium citrate and tartaric acid could narrow the co-deposition potential range of the four elements to -0.8 V to -1.2 V (vs. SCE). The cause was the synergetic effect that trisodium citrate inhibited the reduction of Cu2+ and Sn2+ and tartaric acid promoted the reduction of Zn2+. The reduction of S2O32- was mainly attributed to the induction effect of the metallic ions, and the H+ dissociated from tartaric acid could also promote the cathode process of S2O32-. The reaction mechanism could be summarized as the following steps: (I) Cu(H2C6H5O7)+, Cu2(C6H5O7)+ → Cu, Sn(H2C6H5O7)+, Sn2(C6H5O7)+ → Sn, Zn(C4H5O6)+ → Zn; (II) the desorption of (H2C6H5O7)- and (C6H5O7)-, and the reduction of S2O32- induced by metallic ions and H+. The mechanism studies provided a path of electrolyte design for multicomponent compounds.

En la primera población (LM1 se encontraron valores máximos de 5.6 y menores de 1.4 lesiones cm-2, mientras que en la segunda población (LM2 los promedios máximos y mínimos fueron de 8.0 y 1.5 lesiones cm-2, respectivamente. Se constató diferencia entre las líneas evaluadas en función de la severidad de mancha de curvularia, en los dos experimentos. Con la información obtenida se torna importante considerar los valores de severidad obtenidos en estos experimentos, para el futuro desarrollo de nuevos híbridos de maíz con caracteres contrastantes en el comportamiento de la planta a determinadas enfermedades, asegurando el éxito de un programa de mejoramiento genético. Por otro lado, para futuros trabajos similares se recomienda realizar más de una evaluación y en diferentes estadios fenológicos del cultivo.

    A series of CaIn2S4-reduced graphene oxide (RGO) nanocomposites with different RGO contents were fabricated using a facile hydrothermal approach. During the hydrothermal process, the reduction of graphene oxide to RGO, in situ deposition of synthesized CaIn2S4 nanoparticles on RGO nanosheets and formation of chemical-bonding CaIn2S4-RGO nanocomposites were performed simultaneously. Under visible light irradiation, the as-prepared CaIn2S4-RGO nanocomposites showed enhanced photocatalytic performance for rhodamine B degradation and phenol oxidation. The sample with 5 wt % RGO hybridized CaIn2S4 exhibited the highest photocatalytic activity. The enhancement of photocatalytic performance may be related to the increased adsorption/reaction sites, positive shift of the valence band potential, and high separation efficiency of photogenerated charge carriers due to the electronic interaction between CaIn2S4 and RGO. We hope that this work can not only provide an in-depth study on the photocatalytic mechanism of RGO-enhanced activity, but also provide some insights for fabricating efficient and stable RGO-based photocatalysts in the potential applications of purifying polluted water resources.

    .0 computerized battery (system for evaluation and follow-up of hypothyroid patients for the detection of disorders in children with congenital hypothyropidism (CH. Three groups of children were studied: learning disorders (LD, congenital hypothyroidism (CG and sound controls (SC. The results show that the values of the children from group CH are at an intermediate level between the SC and the LD, which is interpreted as the existance of a subclinical deficit in sustained attention. The discriminatory capacity of the software used allows its inmediate incorporation to the clinical practice of the national CH early diagnosis program as a very useful complementary tool.

    The reactivity of europium with As species in Lewis basic alkali-metal polysulfide fluxes was investigated along with compound formation and the As(3+)/As(5+) interplay vis-à-vis changes in the flux basicity. The compound Na(2)EuAs(2)S(5) containing trivalent As(3+) is stabilized from an arsenic-rich polysulfide flux. It crystallizes in the monoclinic centrosymmetric space group P2(1)/c. Na(2)EuAs(2)S(5) has [As(2)S(5)](4-) units, built of corner sharing AsS(3) pyramids, which are coordinated to Eu(2+) ions to give a two-dimensional (2D) layered structure. A sodium polysulfide flux with comparatively less arsenic led to the As(5+) containing compounds NaEuAsS(4) (orthorhombic, Ama2) and Na(4)Eu(AsS(4))(2) (triclinic, P1) depending on Na(2)S/S ratio. The NaEuAsS(4) and Na(4)Eu(AsS(4))(2) have a three-dimensional (3D) structure built of [AsS(4)](3-) tetrahedra coordinated to Eu(2+) ions. All compounds are semiconductors with optical energy gaps of ∼2 eV.

  8. Spectroelectrochemistry and modeling of enargite (Cu3AsS4) reactivity under atmospheric conditions

    Gow, Robert Nicholas Verne

    Raman spectroscopy has been a useful technology for fundamental studies in the mining industry. Surface changes through oxidation and reduction reactions can be monitored in-situ, allowing the changes to be monitored in real time. In conjunction with cyclic voltammetry, to change the conditions at which a mineral surface is subjected to, reaction and reaction conditions can be identified. The results can then be plotted to create a map similar to that of an EH-pH diagram. In this study, the copper arsenic sulfide mineral, enargite (Cu 3AsS4) was subjected to a series of tests. Relatively pure samples were obtained from Butte, MT and Quirivilca, Peru and used to create mineral electrodes. The electrodes were cycled over an EH range of -1000 to +1000 mV (vs SHE) at pH values ranging from 1 to 13. Changes to the surface of the mineral were identified by comparing Raman spectra to a mineral Raman database. Plotted results were then compared against mass-balanced EH-pH diagrams for the Cu-As-S-H2O system, created using the STABCAL thermodynamic calculation program. Ultimately, the EH-pH diagram is modified based on the results, and an updated version was created. The mass-balanced methodology is applied, in conjunction with Gibbs' phase rule, to an aqueous quaternary system. Variations in EH-pH diagrams of the Cu-As-S-H2O system based on slight changes in concentrations of copper, arsenic and sulfur are examined. Finally, a novel nano-graphene material was tested for its ability to adsorb arsenic. Arsenic remediation, downstream of an enargite leach, remains an unsolved issue. The nano-graphene platelets were not able to successfully reduce arsenic levels in solution below the EPA-required limitation of 10 ppb. A thermodynamic evaluation of the adsorption characterized the process as physisorption, and likely unsuitable for long-term arsenic storage. A functionalized version of the nano-graphene may enhance results.

    The remediation industry has grown exponentially in recent decades. International organizations of practitioners and remediation experts have developed several frameworks for integrating sustainability into remediation projects; however, there has been limited attention to how sustainability is approached and operationalized in sustainable remediation frameworks and practices - or whether sustainability plays any meaningful role at all in sustainable remediation. This paper examines how sustainability is represented in remediation frameworks and the guidance provided for practical application. Seven broad sustainability principles and review criteria are proposed and applied to a sample of six international remediation frameworks. Not all review criteria were equally satisfied and none of the frameworks fully met all criteria; however, the best performing frameworks were those identified as sustainability remediation frameworks. Intra-generational equity was addressed by all frameworks. Integrating social, economic and biophysical components beyond triple-bottom-line indicators was explicitly addressed only by the sustainable remediation frameworks. No frameworks provided principle- or rule-based guidance for dealing with trade-offs in sustainability decisions. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Sustained intervention effects are needed for positive health impacts in populations; however, few published examples illustrate methods for assessing sustainability in health promotion programs. This paper describes the methods for assessing sustainability of the Lifestyle Education for Activity Program (LEAP). LEAP was a comprehensive school-based intervention that targeted change in instructional practices and the school environment to promote physical activity (PA) in high school girls. Previous reports indicated that significantly more girls in the intervention compared with control schools reported engaging in vigorous PA, and positive long-term effects on vigorous PA also were observed for girls in schools that most fully implemented and maintained the intervention 3 years following the active intervention. In this paper, the seven steps used to assess sustainability in LEAP are presented; these steps provide a model for assessing sustainability in health promotion programs in other settings. Unique features of the LEAP sustainability model include assessing sustainability of changes in instructional practices and the environment, basing assessment on an essential element framework that defined complete and acceptable delivery at the beginning of the project, using multiple data sources to assess sustainability, and assessing implementation longitudinally.

    The ConocoPhillips Center for a Sustainable WE2ST (Water-Energy Education, Science, and Technology) is a testament to the power of collaboration and innovation. WE2ST began as a partnership between ConocoPhillips (foundation gift) and the Colorado School of Mines (CSM) with the goal of fostering solutions to water-energy challenges via education, research and outreach. The WE2ST center is a training ground for the next generation of water-energy-social scientists and engineers and is a natural fit for CSM, which is known for its expertise in water resources, water treatment technologies, petroleum engineering, geosciences, and hydrology. WE2ST has nine contributing faculty researchers that combine to create a web of expertise on sustainable energy and water resources. This research benefits unconventional energy producers, water-reliant stakeholders and the general public. Areas of focus for research include water sources (quality and quantity), integrated water-energy solution viability and risk, and social-corporate responsibility. The WE2ST Center currently provides annual support for 8-9 Graduate Fellows and 13 Undergraduate Scholars. Top-tier graduate students are recruited nationally and funded similar to an NSF Graduate Research Fellowship (GRF). Undergraduate Scholars are also recruited from across the CSM campus to gain experience in faculty laboratories and on research teams. All WE2ST students receive extensive professional skills training, leadership development, communication skills training, networking opportunities in the water-energy industries, and outreach opportunities in the community. The corner stone of the WE2ST Center is a focus on communication with the public. Both in social science research teams and in general interactions with the public, WE2ST seeks to be "an honest broker" amidst a very passionate and complex topic. WE2ST research is communicated by presentations at technical conferences, talking with people at public gatherings

    Full Text Available Nanostructured ZnGa2S4 with indirect band gap was prepared by a simple thiourea reduction method. As-prepared samples were characterized by X-ray diffraction (XRD, high resolution transmission electron microscopy (HRTEM, energy-dispersive X-ray spectroscopy (EDX, and UV-Vis diffuse reflectance spectra (UV-Vis. The visible-light photocatalytic activity of the ZnGa2S4 was evaluated by the degradation of methylene blue (MB aqueous solution. The high photoactivities of ZnGa2S4 can be attributed to the small band gap and large surface area, which is beneficial for degradation of pollutants and enhancement of transfer of photogenerated carriers.

    Modern society relies heavily on the Global Navigation Satellite System (GNSS) technology for applications such as satellite communication, navigation, and positioning on the ground and/or aviation in the troposphere/stratosphere. However, ionospheric scintillations can severely impact GNSS systems and their related applications. In this study, a global empirical ionospheric scintillation model is constructed with S4-index data obtained by the FORMOSAT-3/COSMIC (F3/C) satellites during 2007-2014 (hereafter referred to as the F3CGS4 model). This model describes the S4-index as a function of local time, day of year, dip-latitude, and solar activity using the index PF10.7. The model reproduces the F3/C S4-index observations well, and yields good agreement with ground-based reception of satellite signals. This confirms that the constructed model can be used to forecast global L-band scintillations on the ground and in the near surface atmosphere.

  19. The S4-S5 linker acts as a signal integrator for HERG K+ channel activation and deactivation gating.

    Chai Ann Ng

    Full Text Available Human ether-à-go-go-related gene (hERG K(+ channels have unusual gating kinetics. Characterised by slow activation/deactivation but rapid inactivation/recovery from inactivation, the unique gating kinetics underlie the central role hERG channels play in cardiac repolarisation. The slow activation and deactivation kinetics are regulated in part by the S4-S5 linker, which couples movement of the voltage sensor domain to opening of the activation gate at the distal end of the inner helix of the pore domain. It has also been suggested that cytosolic domains may interact with the S4-S5 linker to regulate activation and deactivation kinetics. Here, we show that the solution structure of a peptide corresponding to the S4-S5 linker of hERG contains an amphipathic helix. The effects of mutations at the majority of residues in the S4-S5 linker of hERG were consistent with the previously identified role in coupling voltage sensor movement to the activation gate. However, mutations to Ser543, Tyr545, Gly546 and Ala548 had more complex phenotypes indicating that these residues are involved in additional interactions. We propose a model in which the S4-S5 linker, in addition to coupling VSD movement to the activation gate, also contributes to interactions that stabilise the closed state and a separate set of interactions that stabilise the open state. The S4-S5 linker therefore acts as a signal integrator and plays a crucial role in the slow deactivation kinetics of the channel.

    The exploration of high Faradic redox active materials with the advantages of low cost and low toxicity has been attracting great attention for producing high energy storage supercapacitors. Here, the high Faradic redox active material of Cu7S4-NWs coated on a carbon fiber fabric (CFF) is directly used as a binder-free electrode for a high performance flexible solid state supercapacitor. The Cu7S4-NW-CFF supercapacitor exhibits excellent electrochemical performance such as a high specific capacitance of 400 F g-1 at the scan rate of 10 mV s-1 and a high energy density of 35 Wh kg-1 at a power density of 200 W kg-1, with the advantages of a light weight, high flexibility and long term cycling stability by retaining 95% after 5000 charge-discharge cycles at a constant current of 10 mA. The high Faradic redox activity and high conductance behavior of the Cu7S4-NWs result in a high pseudocapacitive performance with a relatively high specific energy and specific power. Such a new type of pseudocapacitive material of Cu7S4-NWs with its low cost is very promising for actual application in supercapacitors.The exploration of high Faradic redox active materials with the advantages of low cost and low toxicity has been attracting great attention for producing high energy storage supercapacitors.
