Kamehameha Schools, in conjunction with several federal, state, and private organizations, has proposed to conduct conservation management on approximately 5,340 ha (~13,200 acres) of land they own in the vicinity of Kīpukalupea in the North Kona District on the island of Hawai'i. The goal of this program is to restore and enhance the habitat to benefit native plant and animal populations that are currently, or were formerly, found in this site. The initial phase of this project has been focused on various activities including conducting baseline surveys for bird and plant species so Kamehameha Schools could develop a Safe Harbor Agreement (SHA) for the proposed project lands relative to the habitat management and species reintroduction efforts they would like to conduct in the Lupea Project area. This report summarizes methods that were used to collect field data on plant species and communities within the project area, and the results of that initial survey. The information was used to calculate baseline values for all listed threatened or endangered plant species found, or expected to be found, within the project area, and to design a monitoring program to assess changes in plant communities and rare plant species relative to management activities over the duration of the SHA.

With growing evidence for the positive health outcomes associated with a plant-based diet, the study's purpose was to examine the potential of shifting adolescents' food choices towards plant-based foods. Using a real world setting of a school canteen, a set of small changes to the choice architecture was designed and deployed in a secondary school in Yorkshire, England. Focussing on designated food items (whole fruit, fruit salad, vegetarian daily specials, and sandwiches containing salad) the changes were implemented for six weeks. Data collected on students' food choice (218,796 transactions) enabled students' (980 students) selections to be examined. Students' food choice was compared for three periods: baseline (29 weeks); intervention (six weeks); and post-intervention (three weeks). Selection of designated food items significantly increased during the intervention and post-intervention periods, compared to baseline (baseline, 1.4%; intervention 3.0%; post-intervention, 2.2%) χ(2)(2) = 68.1, p food items during the intervention period, compared to baseline. The study's results point to the influence of choice architecture within secondary school settings, and its potential role in improving adolescents' daily food choices.

High-school students' reasoning while constructing plant growth models in a computer-supported educational environment

Science.gov (United States)

Ergazaki, Marida; Komis, Vassilis; Zogza, Vassiliki

2005-08-01

This paper highlights specific aspects of high-school students’ reasoning while coping with a modeling task of plant growth in a computer-supported educational environment. It is particularly concerned with the modeling levels (‘macro-phenomenological’ and ‘micro-conceptual’ level) activated by peers while exploring plant growth and with their ability to shift between or within these levels. The focus is on the types of reasoning developed in the modeling process, as well as on the reasoning coherence around the central concept of plant growth. The findings of the study show that a significant proportion of the 18 participating dyads perform modeling on both levels, while their ability to shift between them as well as between the various elements of the ‘micro-conceptual’ level is rather constrained. Furthermore, the reasoning types identified in peers’ modeling process are ‘convergent’, ‘serial’, ‘linked’ and ‘convergent attached’, with the first type being the most frequent. Finally, a significant part of the participating dyads display a satisfactory degree of reasoning ‘coherence’, performing their task committed to the main objective of exploring plant growth. Teaching implications of the findings are also discussed.

Indoor/Outdoor Air Quality Assessment at School near the Steel Plant in Taranto (Italy

Directory of Open Access Journals (Sweden)

A. Di Gilio

2017-01-01

Full Text Available This study aims to investigate the air quality in primary school placed in district of Taranto (south of Italy, an area of high environmental risk because of closeness between large industrial complex and urban settlement. The chemical characterization of PM2.5 was performed to identify origin of pollutants detected inside school and the comparison between indoor and outdoor levels of PAHs and metals allowed evaluating intrusion of outdoor pollutants or the existence of specific indoor sources. The results showed that the indoor and outdoor levels of PM2.5, BaP, Cd, Ni, As, and Pb never exceeded the target values issued by World Health Organization (WHO. Nevertheless, high metals and PAHs concentrations were detected especially when school were downwind to the steel plant. The I/O ratio showed the impact of outdoor pollutants, especially of industrial markers as Fe, Mn, Zn, and Pb, on indoor air quality. This result was confirmed by values of diagnostic ratio as B(aP/B(gP, IP/(IP + BgP, BaP/Chry, and BaP/(BaP + Chry, which showed range characteristics of coke and coal combustion. However, Ni and As showed I/O ratio of 2.5 and 1.4, respectively, suggesting the presence of indoor sources.

Dusts are one of the main air pollutants emitted during cement manufacturing. A substantial part of these are breathable particles that are less than 10 μm in diameter (PM10), which represent a potential threat for the health of the exposed population. This study aimed at evaluating the short-term effects of PM10 concentrations on the health of children, aged 6-14 years, who attended the schools in Fumane (Italy), in proximity (1.2 km) to a large cement plant. School absenteeism was used as a proxy indicator of child morbidity. Time series of daily school absences and PM10 concentrations were collected for 3 school-years from 2007 to 2010 (541 school-days, 462 children on average). The associations between PM10 concentrations and school absence rates in the same day (lag0) and in the following 4 days (lag1 to lag4) were evaluated using generalised additive models, smoothed for medium/long term trends and adjusted for day of the week, influenza outbreaks, daily temperature and rain precipitations. The average concentration of PM10 in the period was 34 (range: 4-183) μg/m(3). An average 10 μg/m(3) increase of PM10 concentration in the previous days (lag0-4) was associated with a statistically significant 2.5% (95%CI: 1.1-4.0%) increase in the rate of school absences. The highest increase in the absence rates (2.4%; 95%CI: 1.2-3.5%) was found 2 days after exposure (lag2). These findings provide epidemiological evidence of the acute health effects of PM10 in areas with annual concentrations that are lower than the legal European Union limit of 40 μg/m(3), and support the need to establish more restrictive legislative standards.

Previously, we showed that manganese (Mn) levels in settled dust in elementary schools increased at a rate of 34.1% per km closer to a ferro-manganese alloy plant in the rainy season. In this study, we investigated how this environmental pollution indicator varied in the dry season and if there was an association with Mn biomarker levels in school-aged children. Dust samples were collected with passive samplers (disposable Petri dishes) placed in interior and exterior environments of 14 elementary schools. Occipital hair, toenails and blood samples were collected from 173 students aged 7-12 years from three of these schools, with varying distance from the industrial plant. Mn and lead (Pb) levels were measured by graphite furnace atomic absorption spectrometry. Mn concentration geometric means (GM) in dust fall accumulation in interior environments of schools located at 2, 4, 6 and > 6 km-radii from the plant were 2212, 584, 625 and 224 μg Mn/m 2 /30 days, respectively. The modelled rate of change of dust Mn levels decreases by 59.8% for each km further from the plant. Pb levels in settled dust varied between 18 and 81 μg/m 2 /30 days with no association with distance from the plant. Blood lead levels median (range) were 1.2 μg/dL (0.2-15.6), of which 97.8% were children's age; and also with log MnTn (β = 2.31 × 10 -5 , p children exposure to Mn, independently of age, increases significantly with school proximity to the ferro-manganese alloy plant.

A lecture on nuclear physics in primary school

Arh, S.

2004-01-01

I am going to propose the contents of a lecture on nuclear physics and radioactivity in primary school. Contemporary technology, medicine and science exploit intensively the discovered knowledge about processes in atoms and in a nucleus. Mankind has gained huge profit from peaceful applications of nuclear reactions and ionizing radiation. We use the products of nuclear industry every day. But about half of the school population never hears a professional explanation about what is going on in nuclear power plants. Only on some secondary schools students learn about nuclear physics. The lack of knowledge about nuclear processes is the main reason why people show great fear when hearing the words: radiation, radioactivity, nuclear, etc. At last it is now time to give some fundamental lessons on nuclear physics and radioactivity also to pupils in primary school. From my four-year teaching experience in primary school I am suggesting a programme of lectures on nuclear physics and radioactivity. At the end of the lessons we would visit the Krsko Nuclear Power Plant or the Nuclear Training Centre Milan Copic. This could be included in the so called natural science day. Pupils come from the eight class (14 years old) of primary school and have no problems following the explanation. (author)

The training of its staff is one of the pillars of the safe and economical operation of a power plant. This is why power plant owners began to systematically train their staff already in the 50s, and why they created central training facilities. Staff members who have undergone this training make an indispensable contribution to the acceptedly high safety and availability of German power plants. The substantial cost of creating training facilities and of schooling plant staff is considered to be an investment for the future. Low labour turnover permits careful observation and development of staff and leads to a high standard of knowledge and experience. (orig./HSCH) [de

An emission inventory (EI) is a conventional tool to quantify and monitor anthropogenic emissions of greenhouse gases and air pollutants into the atmosphere. Gridded EI can visually show geographical patterns of emissions and their changes over time. These patterns, when available, are often determined using location data collected by regional governments, industries, and researchers. Datasets such as Carbon Monitoring and Action (CARMA, www.carma.org) are particularly useful for mapping emissions from large point sources and have been widely used in the EI community. The EI community is aware of potentially significant errors in the geographical locations of point sources, including power plants. The big challenge, however, is to review tens of thousands of power plant locations around the world and correct them where needed. The Power Plant Mapping Student Project (PPMSP) is a platform designed for students in 4th through 12th grade to improve the geographical location of power plants indicated in existing datasets to benefit international EI research. In PPMSP, we use VENTUS, a web-based platform (http://ventus.project.asu.edu/) that invites citizens to contribute power plant location data. Using VENTUS, students view scenes in the vicinity of reported power plant coordinates on Google Maps. Students either verify the location of a power plant or search for it within a designated radius using various indicators, an e-guide, and a power plant photo gallery for assistance. If the power plant cannot be found, students mark the plant as unverified. To assure quality for research use, the project contains multiple checkpoints and levels of review. While participating in meaningful research that directly benefits the EI research community, students are engaged in relevant science curricula designed to meet each grade level's Next Generation Science Standards. Students study energy, climate change, the atmosphere, and geographical information systems. The curricula is

Aim and purpose of the project: The installation is supposed to serve the pedagogic education of regenerative environmental technology and to allow for practice-oriented education of knowledge. The education plan for the secondary schools in the Land Rhineland Palatinate shows the subject 'Energy and Environment: Technical utilisation of energy'. Furthermore the plant is supposed to be used for teacher trainings in the subject work education in the frame of experts consulting and for demonstration purposes for schools in the district Alzey-Worms. Presentation of the working phases and applied methods: Pupils of secondary schools can be motivated at best for education by clear visual instruction and by practical experience with different subjects. The construction of solar power plant offers the opportunity based upon the performance of the pupils for an action and practice oriented approach to the subject. After the didactic introduction to the subject by means of a small model collector the pupils are going to build the 'larger' plant by themselves according to provided plans of an engineering office, assemble it and put it into operation. It must be proved that the captured solar energy suffices to gain enough warm water for hand washing or even taking a shower. Further working steps consist of increasing the efficiency of the plant and visualising the measurement results on a demonstration wall. At the end of this lesson series the plant is disassembled again and prepared for further use in the next school year. (orig.)

Unique ecological impacts associated with offshore floating nuclear power plants

International Nuclear Information System (INIS)

Adams, S.M.; McLean, R.B.

1979-01-01

The ecological impacts that could occur as a result of site construction and operation of an offshore floating nuclear power plant are identified by comparing the principal ecological features associated with offshore siting with those associated with the siting of onshore estuarine plants. In general, the ecological impacts of offshore nuclear plants should be relatively smaller than those of estuarine plants. Possible factors that could increase the relative impacts of offshore plants are high frequency of contact with schools of fish, siting near inlets to estuaries or other ecologically important areas, and the persistence of halogen residuals. Identifying the potential ecological impacts associated with the siting of offshore plants permits the development of various monitoring programs and measures to minimize these impacts

The impact of whole-plant instruction of preservice teachers' understanding of plant science principles

Science.gov (United States)

Hypolite, Christine Collins

The purpose of this research was to determine how an inquiry-based, whole-plant instructional strategy would affect preservice elementary teachers' understanding of plant science principles. This study probed: what preservice teachers know about plant biology concepts before and after instruction, their views of the interrelatedness of plant parts and the environment, how growing a plant affects preservice teachers' understanding, and which types of activity-rich plant themes studies, if any, affect preservice elementary teachers' understandings. The participants in the study were enrolled in two elementary science methods class sections at a state university. Each group was administered a preinstructional test at the beginning of the study. The treatment group participated in inquiry-based activities related to the Principles of Plant Biology (American Society of Plant Biologists, 2001), while the comparison group studied those same concepts through traditional instructional methods. A focus group was formed from the treatment group to participate in co-concept mapping sessions. The participants' understandings were assessed through artifacts from activities, a comparison of pre- and postinstructional tests, and the concept maps generated by the focus group. Results of the research indicated that the whole-plant, inquiry-based instructional strategy can be applied to teach preservice elementary teachers plant biology while modeling the human constructivist approach. The results further indicated that this approach enhanced their understanding of plant science content knowledge, as well as pedagogical knowledge. The results also showed that a whole-plant approach to teaching plant science concepts is an instructional strategy that is feasible for the elementary school. The theoretical framework for this study was Human Constructivist learning theory (Mintzes & Wandersee, 1998). The content knowledge and instructional strategy was informed by the Principles of Plant

Professional Competence of Student Teachers to Implement Species Identification in Schools – A Case Study from Germany

Full Text Available This study investigates how well prepared student teachers are to implement species identification in school. Data were collected with the help of a questionnaire and a PowerPoint presentation in which local plant and animal species were presented. Participants (n = 357 correctly identified, on average, 23% of the plants and 44% of the animals. They identified plants mainly by flower characteristics and leaves, and animals mainly by shape and colour. Family and school were key sources of participants’ knowledge of species. The self-estimated competence of participants to identify species was positively correlated with their taxonomic knowledge and the amount of time they had spent on species identification during their own schooldays. The number of correctly identified plant and animal species increased with interest in identifying species and participation in species identification courses. Participants considered learner-centred education and experience-based learning, and the use of living organisms to be most important when identifying species in school.

1996-01-01

At the end of 1984, the city of Haessleholm in Sweden started up a 65 MW district heating plant which included a 14 MW solid fuel plant. The plant included a specially-designed fluidised-bed boiler, capable of burning all grades of solid fuel, including organic fuel of such low grade that no other boilers around Haessleholm could use it. By 1992, the district heating system served some 250 detached houses and 6,000 flats as well as several schools and industrial premises. The biofuel boiler provides almost 60% of the energy required.

Conservation and restoration of indigenous plants to improve community livelihoods: the Useful Plants Project

Science.gov (United States)

Ulian, Tiziana; Sacandé, Moctar; Mattana, Efisio

2014-05-01

Kew's Millennium Seed Bank partnership (MSBP) is one of the largest ex situ plant conservation initiatives, which is focused on saving plants in and from regions most at risk, particularly in drylands. Seeds are collected and stored in seed banks in the country of origin and duplicated in the Millennium Seed Bank in the UK. The MSBP also strengthens the capacity of local communities to successfully conserve and sustainably use indigenous plants, which are important for their wellbeing. Since 2007, high quality seed collections and research information have been gathered on ca. 700 useful indigenous plant species that were selected by communities in Botswana, Kenya, Mali, Mexico and South Africa through Project MGU - The Useful Plants Project. These communities range from various farmer's groups and organisations to traditional healers, organic cotton/crop producers and primary schools. The information on seed conservation and plant propagation was used to train communities and to propagate ca. 200 species that were then planted in local gardens, and as species reintroduced for reforestation programmes and enriching village forests. Experimental plots have also been established to further investigate the field performance (plant survival and growth rate) of indigenous species, using low cost procedures. In addition, the activities support revenue generation for local communities directly through the sustainable use of plant products or indirectly through wider environmental and cultural services. This project has confirmed the potential of biodiversity conservation to improve food security and human health, enhance community livelihoods and strengthen the resilience of land and people to the changing climate. This approach of using indigenous species and having local communities play a central role from the selection of species to their planting and establishment, supported by complementary research, may represent a model for other regions of the world, where

Fančovičová, Jana; Prokop, Pavol

2010-10-01

Plants are integral parts of ecosystems which determine life on Earth. People's attitudes toward them are however, largely overlooked. Here we present initial psychometric assessment of self-constructed Plant Attitude Scale (PAS) that was administered to a sample of 310 Slovakian students living in rural areas aged 10-15 years. The final version of PAS consists from 29 Likert-scale items that were loaded to four distinct dimensions (Interest, Importance, Urban trees and Utilization). Mean scores revealed that Slovakian students lack positive attitudes toward plants and that gender had no effect on their mean attitude scores. Living in a family with a garden was associated with a more positive attitude toward plants. Further correlative research on diverse samples containing urban children and experimental research examining the impact of gardening in schools on student attitudes toward plants is required.

Full Text Available School gardens have beneficial effects on children’s dietary behaviors but information on its implementation is scarce. The current study aimed to gain insight in implementation practices of school gardens and in perceptions of key members and children towards a school garden. We conducted twelve interviews involving 14 key members and five focus groups with 38 children from fifth to sixth grade (10–13 years old in four primary schools in Ghent (Flanders, Belgium. We analyzed the interviews and focus groups in NVivo, using thematic analysis. School gardens were mainly initiated to involve children in nature, not to improve vegetable consumption. Participants were positive about having a school garden, experienced facilitating factors (e.g., adaptability of the garden, having a person responsible for the garden, but also various barriers (e.g., difficulties with startup, maintenance during summer holidays and integration in the school curriculum and suggested some solutions (e.g., involving external organizations and parents, expanding the garden and motivating factors for children (e.g., colorful plants, use of gloves. In order to improve implementation and to contribute to children’s health, future school gardening projects should take the recommendations of key members and children into account.

Mineral nutrition of plants: a short history of plant physiology.

Science.gov (United States)

Pennazio, Sergio

2005-01-01

The development of the knowledge on the mineral nutrition of plants begins between the 17th and 18th centuries when some European naturalists gave the first experimental evidences of what had been empirically known for about two millennia. The works of Hales and Ingenhousz were of absolute importance in relation to the transport of water and solutes, and assimilation of "fixed air" (carbon dioxide), respectively. The early chemistry introduced by Lavoisier benefited the first physiologists Senebier and De Saussure to reject the "theory of humus", which imposed the soil as the unique source of carbon. During the first half of the 19th century, Sprengel and Liebig investigated on the problems related to some indispensable mineral salts, while Boussingault and Ville attempted to prove the nitrogen fixation from air without giving any convincing evidence. Liebig was the pioneer of the agricultural chemistry: he epitomised the knowledge of that period by imposing the so-called "law of the minima", already acknowledged by Sprengel, and patronised the use of mineral fertilisers in Europe by devising several formulas of mineral manure. He, however, did not recognise the needs of external supplies of nitrogen salts for the crops, in open dispute with the English school of Lawes and Gilbert, who were instead convinced assertors of such needs. At the end of the 19th century Hellriegel showed that leguminous plants presenting peculiar nodules on their roots could really fix the gaseous nitrogen. From these nodules Beijerinck and Prazmowski isolated for the first time some bacteria which were recognised as the real agents fixing nitrogen. This discovery was of fundamental importance for plant nutrition, only second to the discovery of photosynthesis. Another basic contribution came from early research of Sachs on plants grown on aqueous solutions: these techniques allowed to impose the concept of "essential elements", which was fixed as a principle by Arnon and Stout in 1939

Ukai, M.

2015-01-01

After Fukushima–Daiichi Nuclear Power Plant accident Japanese have thought “Basic radiation knowledge for school education” is very important. Ministry of Education, Culture, Sports, Science and Technology of Japan published supplemental learning textbooks on radiation for school students and teachers written in Japanese in October 2011 just after the accident. These textbooks show the clear explanation of radiation and cover the various topics especially on the accident. Japan Atomic Energy Agency has also published new textbook for secondary school students and teachers written in English in January 2015. English version textbooks are very useful for Japanese students who want be a teacher and also for students from foreign countries in our University. Using these textbooks new class have stated at our University. In this presentation the education programmes at school in Japan and the effects of these textbooks as a practical tool will be discussed. (author)

Science field trips to nuclear power plants - A low capital cost program

Cramer, E.N.; Gabel, C.; Sayles, C.

1991-01-01

School science field trips to nuclear power plants can be quite rewarding to both students and teachers if the right material is used from a perspective different from the textbooks. One does not need a large, expensive facility to have a program useful to students that addresses adult issues understandably. San Onofre Nuclear Generating Station hosted ∼110 visits (simulator tours) averaging 2,700 visitors in each of calendar years 1989 and 1990 after averaging 75 visits in each of the five preceding years. Most audiences were from middle schools located within a 50-mile radius. The station does not have a separate visitor's center; a classroom is reserved at the station's training and education center. The advantage is using real working laboratories; the disadvantage is not having the more traditional displays and interactive models. Therefore, the instructor emphasizes showing the integrated engineering applications of chemistry, physics, and geology - rather than repeating material that is more easily taught in the school's classroom. Generic issues are emphasized rather than the design details of the plant systems

2015-01-01

A diet dominated by plant foods, with limited amounts of refined processed foods and animal products conveys substantial health benefits. This study sought to explore adolescents’ attitudes and perceptions towards plant-based foods. Semi-structured focus group interviews were conducted with adolescents (age 14–15 years) (n = 29) attending an inner city school in Yorkshire, UK. Using a grounded theory methodology, data analysis provided four main categories and related concepts revolving around adolescents’ perspectives on plant-based foods: food choice parameters; perceived drivers and benefits of plant-based foods; environmental food cues; barriers to plant-based food choice. In the emergent grounded theory, a clear disconnect between plant-based foods and the parameters that adolescents use to make food choices, is highlighted. Further, key barriers to adolescents adopting a plant-based diet are differentiated and considered with respect to practice and policy. The analysis offers a framework to remodel and re-present plant-based foods. In this way, it is proposed that a closer connection is possible, with consequent shifts in adolescents’ dietary behaviour towards a more plant-based diet and associated health benefits.

A collection is presented containing 11 papers submitted at a conference on the selection and education of specialists for operation and maintenance of nuclear power plants. The conference was attended by specialists from universities and colleges, research institutes and production plants. It debated the methods and aims of both general and specialized theoretical and practical personnel education, the proposals for teaching centre equipment, the use of simulators, computers and other aids in the teaching process; training on school reactors was included. A proposal was put forward of the system of education, the teaching process itself, the content of the basic theoretical subjects, and the method of testing pupils' knowledge. The importance was stressed of establishing a national coordination centre to safeguard the syllabus, methodology, teaching aids, and also the training proper. The system of personnel education in the Paks nuclear power plant, Hungary, is presented as an example. (M.S.)

Siraf port, a linkage site for the intraction of Jundi Shahpur medical school with the lands of Indian-Pacific oceans

Full Text Available The most important Sasanian-Islamic port of Iran in the Persian Gulf was Siraf, with a total population of 300,000. The ruined site of Siraf lies on the Persian Gulf, 230 Km. south-east of Bushehr. By the time Siraf was mentioned first (c. 850, it was already a flourishing port with merchants dealing with India, East Africa, Madagascar, Malay Peninsula and China. Siraf had a prominent role in the transfer of Indian medical knowledge to Jundi Shahpur medical school during Sasanian period. In addition to Indian medicine and Ayurvedaic medicine, Siraf was the gate of Jundi Shahpur for Egyptian and Hellenistic medicine in the pre-Islamic and Islamic periods. This relationship was bidirectional and the heritage of Jundi Shahpur medical school including its medical books, medicinal plants and medical knowledge were transferred to the East by Indian and Chinese sailors and merchants. The import and export of medicinal plants and the existence of the storages of medicinal plants in Siraf port was mentioned in many times by historical geographists of the middle ages. In conclusion, this Sasanian-Islamic port had a key role in the introduction of medicinal plants and the transmission of knowledge of medicine from India, East Africa, Egypt and China to the rising Jundi Shahpur medical school. The critical function of introduction of oriental medicine and medicinal plants to Iran through Siraf port was continued for several centuries, even after the down of Jundi Shahpur medical school.

Effectiveness of the Solar Panels in the Castro Valley Unified School District Based on Projected Amount of Energy to be Produced

In recent years Americans have warmed to the idea of installing solar panels to their homes and businesses. These panels help reduce the cost of receiving energy from power plants that lose a lot of energy in transportation. These power plants provide energy by burning gas or coal producing emissions that add to the growing problem of pollution and global warming. In 2010 the Castro Valley Unified School District decided to add solar panels to Canyon Middle School, Castro Valley High School, and Castro Valley Adult School. We researched whether the solar panels reached their projected amount of energy (74%) for the sites where the panels were placed. The solar panels at all three sites were found to exceed these projected amounts. The solar panels at each site produce a little over 74% for the each school.

Can high school gardens in cold climates influence vegetable intake in the absence of nutrition education? This study followed a before/after design where student tray-waste data were collected using the quarter-waste method. The study took place March-April 2012 in a high school in upstate New York. The subjects were 370 enrolled high school students that purchased lunch from the school cafeteria. Prior to the introduction of garden greens in the salad, salads were served as usual. On April 24, harvested greens were included in the salad, and changes in selection and plate waste were measured. When the salad bar contained garden produce, the percentage of students selecting salad rose from 2% to 10% (p school gardens increased selection and intake of school-raised produce. Although a third was not eaten, it is promising to see that still more produce was consumed compared to the past. ©2015 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

The questionaire is filled in before visiting the nuclear power plant Krsko. TARGET GROUP: Technical Musem, in cooperation with Hrvatska elektroprivreda, has been organizing high-school students' visits to the nuclear power plant Krsko since 1989. From all schools that have so far visited the nuclear power plant, Zagreb high schools and technical schools are the most represented ones. The respondents are aged between 16 and 20. The copies of the survey that have been filled in during 2000/2001 are to be analyzed, and the expected number of the respondents is about 600. QUESTIONS: Survey questions reflected several different fields, all in some sort of connection to nuclear energetics. Among them are: -present and future energy resources acceptability of different types of power plants environmental protection and global warming radioactivity radioactive waste issues nuclear power plants types of information resources. Such a wide range of different subjects included in the survey has been chosen so that, after its analysis, further efforts can be taken in quality informing of insufficiently known issues. Also, this kind of public poll will provide the Museum and Hrvatska elektroprivreda with relevant findings about the climate of opinion and the thinking of young generations towards energetics issues and the cause of its future development. The analyzed results of the survey present only a fragment of the material, later to be published in a separate publication. (author)

Color me healthy: food diversity in school community gardens in two rapidly urbanising Australian cities.

Guitart, Daniela A; Pickering, Catherine M; Byrne, Jason A

2014-03-01

Community garden research has focused on social aspects of gardens, neglecting systematic analysis of what food is grown. Yet agrodiversity within community gardens may provide health benefits. Diverse fruit and vegetables provide nutritional benefits, including vitamins, minerals and phytochemicals. This paper reports research that investigated the agro-biodiversity of school-based community gardens in Brisbane and Gold Coast cities, Australia. Common motivations for establishing these gardens were education, health and environmental sustainability. The 23 gardens assessed contained 234 food plants, ranging from 7 to 132 plant types per garden. This included 142 fruits and vegetables. The nutritional diversity of fruits and vegetable plants was examined through a color classification system. All gardens grew fruits and vegetables from at least four food color groups, and 75% of the gardens grew plants from all seven color groups. As places with high agrodiversity, and related nutritional diversity, some school community gardens can provide children with exposure to a healthy range of fruit and vegetables, with potential flow-on health benefits.

Pollier, Pierre M.

1989-01-01

Since the Chernobyl accident in April 1986, public opinion in France has changed considerably. Four national surveys carried out over the last two-and-a-half years have shown significant decreases in public approval of nuclear energy (43 percent in October 1988). However, there is no current structured opposition to nuclear power plants. The French public takes nuclear power for granted, but prefers solar energy. It is aware that nuclear power will play an important role in energy supply and that EDF did not build more plants than necessary. It has confidence in the French technique (75 percent), in EDF ability to operate nuclear power plants without serious incidents (55 percent), and in the ability of EDF engineers to deal with a serious accident (50 percent) even though they believe a serious accident could occur (75 percent). However, the situation created by the Chernobyl accident resulted in changes to the EDF information policy. EDF undertook extensive information programs on nuclear power and energy matters during the first years of the program 1975 to 1983), and followed them by a period of less extensive information focussed on electricity. Relations around the nuclear power plant sites between EDF and the public, elected representatives and the media, which had always been close, were reinforced. Information packages were prepared and distributed. Contacts with Textbook Publishers have enabled fruitful exchanges of information, especially during visits to nuclear facilities (power plants, fuel enrichment plants, operating simulators). Remarkable results have been seen in the textbooks concerned. Films, usually videocassettes, are loaned out free of charge. Lectures are a channel of information frequently used by schools since they are free, fit well into the program of some grades, and do not take up too much of the students' time. Visits are considered to be an Excellent Source of Information. Many local initiatives have been taken by plants and schools

Teaching Photosynthesis in a Compulsory School Context. Students’ Reasoning, Understanding and Interactions.

Directory of Open Access Journals (Sweden)

Helena Näs

2011-02-01

Full Text Available According to previous research, students show difficulties in understanding photosynthesis and respiration, and basic ecological concepts like energy flow in ecosystems. There are successful teaching units accomplished in this area and many of them can be described as inquiry-based teaching. One definition of inquiry-based teaching is that it involves everything from finding problems, investigating them, debating with peers and trying to explain and give solutions. Accordingly students need to be confronted with challenging questions and empirical data to reason about and teachers need to implement student-generated inquiry discussion since students often stay silent and do not express their thoughts during science lessons. This thesis will focus on young peoples’ understanding of the functioning of plants, students’ participation during biology lessons, and how biology teaching is accomplished in primary and secondary school.Two school classroom projects focusing on teaching about plants and ecology are described. Four teachers and their 4th, 5th and 6th grade classes plus two science teachers and their three 8th grade classes collaborated. Photosynthesis and respiration were made concrete by using tasks where plants, plant cells, germs, seeds and the gas exchange were used. The aim was to listen to students’ reasoning in both teaching and interview situations. Learning outcome, as described by students’ reasoning in the classrooms and in individual interviews but also by their test results, is especially focused. Student-student and student-teacher interactions have been analysed with an ethnographic approach in the classroom context.The plant tasks encouraged the students’ in primary school to develop scientific reasoning and the interviews confirmed that the students had learned about photosynthesis. The ecology teaching in secondary school showed a substantial understanding confirmed both by students’ oral and written

The data were collected in the latter half of 1977 by the International Brotherhood of Electrical Workers (IBEW) in a survey of union locals in nuclear power plants. The survey results provided substantial evidence that workers in United States nuclear power plants have a relatively high level of education, training, and skill development. Analysis of average education by age did not reveal any significant differences in years of schooling between younger and older workers. Very high rates of participation in formal training programmes were reported by all types of workers. The most common type of training programme was held on-site at the power plant and was provided by utility personnel. The majority of workers reported previous work experience related to nuclear power plant activities. Almost one-third of the workers had been directly involved in nuclear energy in a previous job, the majority of these through the United States Navy nuclear programme. However, the newer plants are hiring relatively fewer persons with previous nuclear experience. (author)

Plants release airborne chemicals that can convey ecologically relevant information to other organisms. These plant volatiles are known to mediate a large array of, often complex, interactions between plants and insects. It has been suggested that plant volatiles may have similar importance in mediating interactions among plant species, but there are few well-documented examples of plant-to-plant communication via volatiles, and the ecological significance of such interactions has been much debated. To date, nearly all studies of volatile-mediated interactions among plant species have focused on the reception of herbivore-induced volatiles by neighboring plants. We recently documented volatile effects in another system, demonstrating that the parasitic plant Cuscuta pentagona uses volatile cues to locate its hosts. This finding may broaden the discussion regarding plant-to-plant communication, and suggests that new classes of volatile-meditated interactions among plant species await discovery.

This study conducted a survey to gather information on the knowledge of Laotian high school students on nuclear energy. This study prepared an original 11-pages textbook that briefly introduced nuclear energy and related matters in Lao. One hundred high school students belonging to a public high school with a good reputation in Savannakhet Province were requested to read the textbook approximately in a half day to tell subjective impression on the amount of prior knowledge on the contents of each section. The survey revealed the knowledge of the high school students on the nuclear energy and related matters was quite limited although the official textbooks used in the secondary education in Laos contain quite a few explanations on structure of atom, chemical and nuclear reaction, structure of nuclear power plants, the chain and fusion reactions, and so on.

Automated detection of chemical threats is essential for an early warning of a potential attack. Harnessing plants as bio-sensors allows for distributed sensing without a power supply. Monitoring the bio-sensors requires a specifically tailored hyperspectral system. Tobacco plants have been genetically engineered to de-green when a material of interest (e.g. zinc, TNT) is introduced to their immediate vicinity. The reflectance spectra of the bio-sensors must be accurately characterized during the de-greening process for them to play a role in an effective warning system. Hyperspectral data have been collected under laboratory conditions to determine the key regions in the reflectance spectra associated with the degreening phenomenon. Bio-sensor plants and control (nongenetically engineered) plants were exposed to TNT over the course of two days and their spectra were measured every six hours. Rochester Institute of Technologys Digital Imaging and Remote Sensing Image Generation Model (DIRSIG) was used to simulate detection of de-greened plants in the field. The simulated scene contains a brick school building, sidewalks, trees and the bio-sensors placed at the entrances to the buildings. Trade studies of the bio-sensor monitoring system were also conducted using DIRSIG simulations. System performance was studied as a function of field of view, pixel size, illumination conditions, radiometric noise, spectral waveband dependence and spectral resolution. Preliminary results show that the most significant change in reflectance during the degreening period occurs in the near infrared region.

School environment and school injuries

Full Text Available Background: Although injuries at school are an important issue in public health, environmental factors in schools and school yards have seldom been the focus of school injury research. The goal of our investigation was to examine the effect of environmental factors on school injuries. Methods: Nine comprehensive Finnish schools registered school injuries over a period of two school years. Injuries were classified as being associated with environmental factors, suspected environmental factors, and others. The consensus between two independent classifiers was 81%. Results: A total of 722 injuries were classified. In 11.6% of these injuries, the physical environment factor was evident, and in 28.1% of the injuries, physical environment was suspected of being a contributory risk factor. Thus the physical environment of the school was a contributing factor in over a third (39.7% of injuries occurring in the school, on the school yard or during the journey to or from school. In this study, conducted in Finland, ice on the ground was mentioned most frequently as an environmental risk factor. Conclusions: In Finland, the Nordic weather conditions are not taken into account in the school yard and playground plans as they ought to from the safety point of view. An initiative has been launched on a mandatory wintertime master plan for every school yard.

Present status of Radiation and Nuclear Education at High School in Japan

1999-01-01

A special committee for 'Radiation and Nuclear Education' made an investigation into textbooks for social and science courses at high school in 1996. The committee concluded that descriptions of subjects related to energy, radiation and nuclear power in textbooks should be more substantial . In textbooks for social course, nuclear power was described from the point of view of resource, energy and environment. Some of the textbooks described that Chernobyl power plant's accident and nuclear weapons testing contaminated and destructed the earth environment. Descriptions about nuclear power were perceptional and one-sided . In textbooks for science course, subjects related to radiation, nucleus, nuclear reactor and nuclear power plant were described in detail to a certain extent . Descriptions about radiation hazard and radiation utilization were objective and balanced. In order that high school students can understand objectively nuclear power as a energy resource and conservation of the earth environment, the committee recommended the government course guidelines to be revised.

Nakanishi, Tomoko M.

2012-01-01

After Fukushima nuclear power plant accident, more than 40 academic staffs at Graduate School of Agricultural and Life Sciences, The Univ. of Tokyo, have been conducted agricultural research integrating all of the departments and facilities. They were divided into several groups, such as grain, animal stock, fishery, trees, wild lives, etc. The agricultural research is highly related to nature itself; therefore, cooperative research gathering several kinds of researchers is needed. For example, to analyze the radioactive accumulation in rice, not only rice breeding researcher but also soil researcher, water management researcher, etc. are needed to discuss the movement or pathway of radioactive nuclides in the field. We found that the fallout was adsorbed at the surface of anything expanded and exposed to the air at the time of the accident, such as soil surface, plant leaves, tree trunks, etc. The adsorption comes stronger with time so that the radioactivity in soil does not move downward any more after several months, in spite of much rain. In the case of plants, the radioactivity still remains as dots on the surface of the tissue and it is very difficult to remove the nuclides even by washing with acids. Mushrooms were found to accumulate high radioactivity, not only the fallout from Fukushima's accident but also the fallout in 1960's after nuclear test bomb. (author)

[Exposure of schoolchildren and teachers to noise at school].

Science.gov (United States)

Koszarny, Z; Goryński, P

1990-01-01

The factor of decisive influence on the acoustic climate in rooms is the inner noise, which is dependent in schools on the activity of children, overcrowding of classes and inadequate use of technical protective means. The inappropriate location of schools, although also important from the standpoint of acoustics, is a much lower source of noise than it is generally assumed. Particularly unfavourable acoustic conditions are in elementary schools with over 300 children in one shift. The spaces with the highest noise level include corridors, especially during recesses between lessons. The noise level in them is in the range of an equivalent sound A 60-95 dB, and the most frequent noise level is 80 dB. In a large part of schools the acoustic conditions in the corridors during recesses approach the critical values accepted for hearing protection in industrial plants, in some schools they are even exceeded. The situation is also unfavourable in other rooms such as doctor's office, director's room, reading rooms, rooms for teachers. These rooms are situated usually without taking into consideration of the acoustic conditions. This is particularly true of teachers' rooms which should give the teachers the possibility of resting before the next lesson. During lessons the noise level decreases in all rooms. However, the noisiest among them, corridors, classes situated near the hall for physical exercises and day-room, have still up to about 65 dB noise level. Generally speaking, in about 60% of rooms the acoustic conditions are below the recommended standard. The main cause, apart from overcrowding of schools, is low acoustic absorption ability of school rooms, and poor acoustic insulation ability of the doors in schools.

1978-01-01

Experience in education and advanced training of nuclear engineers in the GDR is reviewed. The basic education of engineers is carried out at universities and colleges. Graduate engineers who have been working in non-nuclear industries for a longer time receive their basic education in nuclear engineering through postgraduate studies. Graduate engineers with a basic knowledge of nuclear engineering are trained at the Nuclear Power Plant School of the Rheinsberg nuclear power plant and at the nuclear power plants of the GDR under operational conditions relating to their future job. In addition to basic theoretical knowledge, training at a nuclear power plant simulator plays an important role. This permits training of the staff under normal operating conditions including transient processes and under unusual conditions. Further particular modes of advanced professional training such as courses in radiation protection and further postgraduate studies are described. This system of education has proved successful. It will be developed further to meet the growing demands. (author)

After the reactor accident of Fukushima nuclear power plant in Japan on March 11, 2011, many food adopted widely in school food service such as rice, wheat, milk are known to have risk for radioactivity contamination. To protect all children from exposure, the authors quantitatively examined risk assessment coming from food and conclude that radioactivity due to cesium 137 in rice, wheat, and milk for school lunch should be less than 10 Bq/kg and, furthermore from 2013, as lower as possible and less than 5 Bq/kg.

Gasper, Joseph; DeLuca, Stefanie; Estacion, Angela

2014-01-01

Youth who switch schools are more likely to demonstrate a wide array of negative behavioral and educational outcomes, including dropping out of high school. However, whether switching schools actually puts youth at risk for dropout is uncertain, since youth who switch schools are similar to dropouts in their levels of prior school achievement and engagement, which suggests that switching schools may be part of the same long-term developmental process of disengagement that leads to dropping out. Using data from the National Longitudinal Survey of Youth 1997, this study uses propensity score matching to pair youth who switched high schools with similar youth who stayed in the same school. We find that while over half the association between switching schools and dropout is explained by observed characteristics prior to 9th grade, switching schools is still associated with dropout. Moreover, the relationship between switching schools and dropout varies depending on a youth's propensity for switching schools. PMID:25554706

Iron deficiency anaemia is an important health problem in Morocco. This study was conducted to estimate the prevalence of anaemia among school children in Kenitra. The sample represents school children of all educational levels and age ranged between 6-15 years. The level of hemoglobin, haematocrit, mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration was measured in a group of 271 school children. The seric iron was assessed and anaemia was defined when hemoglobin education of the mother and anaemia in children (p = 0.004) but not with the family income. It is concluded that improving the economic status of the family, women education and health education about balanced animal and plant food consumption are recommended strategies to reduce the burden of anaemia.

School gardening programmes are among the most promising interventions to improve children's vegetable intake. Yet, low vegetable intake among children remains a persistent public health challenge. This study aimed to explore children's perspectives, experiences, and motivations concerning school gardening in order to better understand and increase its potential for health promotion. Using participant observation and semi-structured interviews, we provided 45 primary schoolchildren (9-10 years) from Amsterdam, who participated in a comprehensive year-round school gardening programme, the opportunity to share their experiences and ideas on school gardening. Children particularly expressed enjoyment of the outdoor gardening portion of the programme as it enabled them to be physically active and independently nurture their gardens. Harvesting was the children's favourite activity, followed by planting and sowing. In contrast, insufficient gardening time and long explanations or instructions were especially disliked. Experiencing fun and enjoyment appeared to play a vital role in children's motivation to actively participate. Children's suggestions for programme improvements included more autonomy and opportunities for experimentation, and competition elements to increase fun and variety. Our results indicate that gaining insight into children's perspectives allows matching school gardening programmes more to children's wishes and expectations, thereby potentially enhancing their intrinsic motivation for gardening and vegetable consumption.

Children are particularly susceptible to air pollution and schools are examples of urban microenvironments that can account for a large portion of children's exposure to airborne particles. Thus this paper aimed to determine the sources of primary airborne particles that children are exposed to at school by analyzing selected organic molecular markers at 11 urban schools in Brisbane, Australia. Positive matrix factorization analysis identified four sources at the schools: vehicle emissions, biomass burning, meat cooking and plant wax emissions accounting for 45%, 29%, 16% and 7%, of the organic carbon respectively. Biomass burning peaked in winter due to prescribed burning of bushland around Brisbane. Overall, the results indicated that both local (traffic) and regional (biomass burning) sources of primary organic aerosols influence the levels of ambient particles that children are exposed at the schools. These results have implications for potential control strategies for mitigating exposure at schools. - Highlights: • Selected organic molecular markers at 11 urban schools were analyzed. • Four sources of primary organic aerosols were identified by PMF at the schools. • Both local and regional sources were found to influence exposure at the schools. • The results have implications for mitigation of children's exposure at schools. - The identification of the most important sources of primary organic aerosols at urban schools has implications for control strategies for mitigating children's exposure at schools

Adolescents who do not get enough sleep are more likely to be overweight; not engage in daily physical activity; suffer from depressive symptoms; engage in unhealthy risk behaviors such as drinking, smoking tobacco, and using illicit drugs; and perform poorly in school. However, insufficient sleep is common among high school students, with less than one third of U.S. high school students sleeping at least 8 hours on school nights. In a policy statement published in 2014, the American Academy of Pediatrics (AAP) urged middle and high schools to modify start times as a means to enable students to get adequate sleep and improve their health, safety, academic performance, and quality of life. AAP recommended that "middle and high schools should aim for a starting time of no earlier than 8:30 a.m.". To assess state-specific distributions of public middle and high school start times and establish a pre-recommendation baseline, CDC and the U.S. Department of Education analyzed data from the 2011-12 Schools and Staffing Survey (SASS). Among an estimated 39,700 public middle, high, and combined schools* in the United States, the average start time was 8:03 a.m. Overall, only 17.7% of these public schools started school at 8:30 a.m. or later. The percentage of schools with 8:30 a.m. or later start times varied greatly by state, ranging from 0% in Hawaii, Mississippi, and Wyoming to more than three quarters of schools in Alaska (76.8%) and North Dakota (78.5%). A school system start time policy of 8:30 a.m. or later provides teenage students the opportunity to achieve the 8.5-9.5 hours of sleep recommended by AAP and the 8-10 hours recommended by the National Sleep Foundation.

Plant stress signalling: understanding and exploiting plant-plant interactions.

Science.gov (United States)

Pickett, J A; Rasmussen, H B; Woodcock, C M; Matthes, M; Napier, J A

2003-02-01

When plants are attacked by insects, volatile chemical signals can be released, not only from the damaged parts, but also systemically from other parts of the plant and this continues after cessation of feeding by the insect. These signals are perceived by olfactory sensory mechanisms in both the herbivorous insects and their parasites. Molecular structures involved can be characterized by means of electrophysiological assays, using the insect sensory system linked to chemical analysis. Evidence is mounting that such signals can also affect neighbouring intact plants, which initiate defence by the induction of further signalling systems, such as those that increase parasitoid foraging. Furthermore, insect electrophysiology can be used in the identification of plant compounds having effects on the plants themselves. It has been found recently that certain plants can release stress signals even when undamaged, and that these can cause defence responses in intact plants. These discoveries provide the basis for new crop protection strategies, that are either delivered by genetic modification of plants or by conventionally produced plants to which the signal is externally applied. Delivery can also be made by means of mixed seed strategies in which the provoking and recipient plants are grown together. Related signalling discoveries within the rhizosphere seem set to extend these approaches into new ways of controlling weeds, by exploiting the elusive potential of allelopathy, but through signalling rather than by direct physiological effects.

2018-04-01

The effects of three horticulture-related activities (HRAs), including floral arranging, planting, and flower pressing were compared to see if they influenced changes on a stress scale and on salivary cortisol concentrations (SCC) in maladjusted elementary school children. Twenty maladjusted elementary school children were randomly assigned either to an experimental or control group. The control group carried out individual favorite indoor activities under the supervision of a teacher. Simultaneously, the ten children in the experimental group participated in a HRA program consisting of flower arrangement (FA), planting (P), and flower pressing (PF) activities, in which the other ten children in the control group did not take part. During nine sessions, the activities were completed as follows: FA-FA-FA, P-P-P, and PF-PF-PF; each session lasted 40 min and took place once a week. For the quantitative analysis of salivary cortisol, saliva was collected from the experimental group one week before the HRAs and immediately after the activities for 9 consecutive weeks at the same time each session. In the experimental group, stress scores of interpersonal relationship, school life, personal problems, and home life decreased after the HRAs by 1.3, 1.8, 4.2, and 1.3 points, respectively. In particular, the stress score of school life was significantly reduced (P < 0.01). In addition, from the investigation of the SCCs for the children before and after repeating HRAs three times, it was found that flower arrangement, planting, and flower pressing activities reduced the SCCs by ≥37% compared to the SCCs prior to taking part in the HRAs. These results indicate that HRAs are associated with a reduction in the stress levels of maladjusted elementary school children. Copyright © 2018. Published by Elsevier Ltd.

Screening for anemia has been performed in schools in Japan for over 30 years. The long-term effect of the nuclear power plant disaster on the prevalence of anemia in school age children is unknown. This research was performed to evaluate the prevalence of anemia in school age children and to determine grade-level and gender-related reference hemoglobin (Hb) levels prior to the nuclear disaster. Data for this research were obtained from results of screening for anemia obtained by venous blood sampling in schools in 2002. Mean Hb levels were calculated for each grade level (elementary school grades 1-6 and junior high school years 1-3) and according to gender, and the prevalence of anemia was determined. In our research, Tokyo Health Service Association guidelines were used to determine reference Hb levels for anemia. We demonstrated that Hb levels in boys increased with age during childhood and adolescence (from 13.1 ± 0.7 g/dL in 7 year olds to 14.9 ± 1.1 g/dL in 15 year olds); in girls, Hb levels peaked at menarche (13.7 ± 0.8 g/dL in 12 year olds), decreasing slightly thereafter (13.4 ± 1.1 g/dL in 15 year olds). The prevalence of anemia was 0.26% in elementary school boys, 0.27% in elementary school girls, and 1.21% in junior high school boys. The prevalence of anemia in second- and third-year junior high school girls was lower than that in first-year junior high school girls. Among all junior high school girls, 5.73% had mild anemia. Iron-deficiency anemia is the commonest type of anemia in high school girls, secondary to the relative lack of iron due to menstruation, the growth spurt and exercise. Appropriate dietary therapy and treatment of anemia, together with education about the dietary prevention of anemia, are important to reduce the prevalence of anemia in high school students. When complete blood counts are performed in regions thought to be affected by the Fukushima nuclear power plant disaster, our report can serve as a reference during

Screening for anemia has been performed in schools in Japan for over 30 years. The long-term effect of the nuclear power plant disaster on the prevalence of anemia in school age children is unknown. This research was performed to evaluate the prevalence of anemia in school age children and to determine grade-level and gender-related reference hemoglobin (Hb) levels prior to the nuclear disaster. Data for this research were obtained from results of screening for anemia obtained by venous blood sampling in schools in 2002. Mean Hb levels were calculated for each grade level (elementary school grades 1-6 and junior high school years 1-3) and according to gender, and the prevalence of anemia was determined. In our research, Tokyo Health Service Association guidelines were used to determine reference Hb levels for anemia. We demonstrated that Hb levels in boys increased with age during childhood and adolescence (from 13.1±0.7 g/dL in 7 year olds to 14.9±1.1 g/dL in 15 year olds); in girls, Hb levels peaked at menarche (13.7±0.8 g/dL in 12 year olds), decreasing slightly thereafter (13.4±1.1 g/dL in 15 year olds).

Body mass index (BMI) is known to vary by individual characteristics, but little is known about whether BMI varies by school and by school characteristics. Nationally representative samples of United States schools and students are used to determine the extent to which BMI and percent of students at or above the 85th percentile of BMI vary by school and by school characteristics. Data from the 1991-2004 Monitoring the Future (MTF) study were analyzed in 2006 and 2007. A relatively small proportion of variance in BMI lies between schools; intraclass correlations are on the order of 3%. Still, this is sufficient variation to provide very different environments for students attending schools that are low versus high in average BMI. There is some modest variation by school type (public, Catholic private, non-Catholic private); school size (number of students in the sampled grade); region of the country; and population density. There is more variation as a function of school socioeconomic status (SES) and racial/ethnic composition of the school. School SES in particular was negatively associated with BMI levels, even after controlling individual-level SES and racial/ethnic status. The residual differences in BMI by school suggest that some characteristic of the school and/or community environment--perhaps cultural factors or peer role modeling or differences in school food, beverage, or physical education policies--facilitate obesity in schools with a high concentration of lower socioeconomic students, beyond individual-level factors.

Preliminary project concerning the straw-fueled combined power-heat plant to be constructed at Glamsbjerg

Power and heat generation based on biomass gasification is of great importance due to its beneficial environmental effects and good economy. This report concerns a preliminary project on feasibility and problems of implementing a dual-purpose power plant, supplying both power and district heating to several schools, swimming pools and other public facilities at Glamsbjerg (Funen). The plant is to be based on thermal gasification (pyrolysis) of straw and use of the gas in a diesel engine. The diesels operate the power generator, and their waste heat should be utilized in the local district heating network. In order to establish a stable and flexible straw supply to the plant an evaluation of resources in the area has been carried out. Apart from straw-derived fuel the plant is planned to use natural gas for start and maintenance of the process. The prices of the combined plant and of the fuel processing are estimated in the report. (EG)

All p-values are assessed based on a likelihood ratio test comparing the likelihood of a contagion model to that of a null model with no contagion. On average, mass killings involving firearms occur approximately every two weeks in the US, while school shootings occur on average monthly. We find that state prevalence of firearm ownership is significantly associated with the state incidence of mass killings with firearms, school shootings, and mass shootings.

To gain a deeper understanding of how Swedish head school nurses perceive their leadership in developing school health care. A well-functioning school health care is important for promoting the health of children and young people. Constructivist-grounded theory was used to analyse 11 individual interviews with nine head school nurses. Head school nurses strive to find a balance between what they experience as vague formal goals and strong informal goals which leads to creating local goals in order to develop school health care. The head school nurse's job is experienced as a divided and pioneering job in which there is uncertainty about the leadership role. They provide individual support to school nurses, are the link between school nurses and decision makers and highlight the importance of school nurses' work to organizational leaders. This study shows that school health care needs to be founded on evidence-based methods. Therefore, a structured plan for education and training in school health care management, based on research and in cooperation with the academic world, would develop the head school nurses' profession, strengthen the position of school health care and advance the school nurses' work.

Adequate dietary iodine intake in children is essential for optimal physical and neurological development. Whether lower dietary animal food and salt intake may adversely affect iodine status is under discussion. We examined the association between dietary animal:plant protein ratio with 24-h urinary iodine excretion (24-h UI, μg/d), and whether this is modified by salt intake. A 24-h UI was measured in 1959 24-h urine samples from 516 6- to 12-year-old participants of the Dortmund Nutritional and Anthropometric Longitudinally Designed Study. Parallel 3 d weighed food records were used to estimate dietary intakes. Protein sources were classified as dairy, animal and plant. A repeated-measures regression model (PROC MIXED) was used to analyse the effect of animal:plant protein ratios on 24-h UI. plant protein ratios ranged from 0.5 (95 % CI 0.4, 0.6) to 1.6 (95 % CI 1.4, 1.9) (lowest and highest quartile). After adjustment for total energy intake, main dietary iodine sources (dairy and salt intake), and further covariates, the inter-individual variation in animal:plant protein ratio was significantly associated with variation in 24-h UI. One unit higher animal:plant protein ratio predicted 6 μg/d higher 24-h UI (P= 0.002) in boys and 5 μg/d (P= 0.03) in girls. This relationship was partially mediated by a higher salt intake at higher animal:plant protein ratios. These results suggest that lower consumption of animal protein is associated with a small decline in iodine excretion, partially mediated by decreased salt intake. Because limited salt and increased intake of plant-based foods are part of a preferable healthy food pattern, effective nutrition political strategies will be required in the future to ensure appropriate iodine nutrition in adherent populations.

School gardening programmes are among the most promising interventions to improve children’s vegetable intake. Yet, low vegetable intake among children remains a persistent public health challenge. This study aimed to explore children’s perspectives, experiences, and motivations concerning school gardening in order to better understand and increase its potential for health promotion. Using participant observation and semi-structured interviews, we provided 45 primary schoolchildren (9–10 years) from Amsterdam, who participated in a comprehensive year-round school gardening programme, the opportunity to share their experiences and ideas on school gardening. Children particularly expressed enjoyment of the outdoor gardening portion of the programme as it enabled them to be physically active and independently nurture their gardens. Harvesting was the children’s favourite activity, followed by planting and sowing. In contrast, insufficient gardening time and long explanations or instructions were especially disliked. Experiencing fun and enjoyment appeared to play a vital role in children’s motivation to actively participate. Children’s suggestions for programme improvements included more autonomy and opportunities for experimentation, and competition elements to increase fun and variety. Our results indicate that gaining insight into children’s perspectives allows matching school gardening programmes more to children’s wishes and expectations, thereby potentially enhancing their intrinsic motivation for gardening and vegetable consumption.

To test the hypothesis that participation in the School Breakfast Program by low-income children is associated with improvements in standardized achievement test scores and in rates of absence and tardiness, children in grades 3 through 6 were studied in the Lawrence, Mass, public schools, where the School Breakfast Program was begun at the start of the second semester 1986-1987 school year. The changes in scores on a standardized achievement test and in rates of absence and tardiness before and after the implementation of the School Breakfast Program for children participating in the program were compared with those of children who also qualified but did not participate. Controlling for other factors, participation in the School Breakfast Program contributed positively to the 1987 Comprehensive Tests of Basic Skills battery total scale score and negatively to 1987 tardiness and absence rates. These findings suggest that participation in the School Breakfast Program is associated with significant improvements in academic functioning among low-income elementary school children.

The compounds to study were selected based on the bioassays performed concomitant with the fractionation. Our results show that plants traditionally used as wound healing agents contain polysaccharides basically of pectin nature with immunomodulating activities. These pectins all have different and new structures. Several of the plants also contain compounds with effects related to antioxidant properties. These compounds are mainly of polyphenolic nature. Three of these are new compounds from Nature, while 32 was for the first time described from the plant they were isolated from. This review gives an overview of the most important results obtained during the 20 year long collaboration between Department of Traditional Medicine, Bamako, Mali, and Department of Pharmacognosy, School of Pharmacy, University of Oslo, Norway. Our studies showed that ethnopharmacological information is important for the determination of screening and chemical methods to be used for studies of plants used in traditional medicine.

Full Text Available Life-long education is the important factor of adult’s effective social functioning. In contemporary informational society this statement is considered to be true. However, content and technological aspects of a life-long education have not been worked out in detail, therefore, those aspects are at the center of Russian and foreign specialists’ debates. Studying the development of adult schools during the Soviet period could have a heuristic value. Throughout this period we can trace effective and diverse experience in organizing adult education through variety of school types. Education of Soviet nation was seen to be a state priority. From the one hand, in that time it led to unification of adult education schools, form the other hand, it contributed to forming a base for education of various strata of society. During the Soviet epoch school system evolved, with school’s purposes and curricula changing: from fight against in 1920–1940-s, knowledge level renewal in post-war period (evening schools for young people living in rural areas or working at plants to improving standard of life, providing opportunities for creativity and personal security (Adult education centers. History of adult education development in Russia that is being shaped nowadays may rest on predecessors’ experience to reveal some risks and learn a lesson relevant to new generations of specialists in adult education.

Microorganisms are vital to environmental health, yet their association with disease often overshadows these benefits. Building citizen-science activities around the positive role of microorganisms and an understanding of their ubiquity can begin to dispel misconceptions while simultaneously engaging the public in research. Here, we describe a citizen-science microbiology project geared toward implementation in middle and high school classrooms. Students culture environmental microorganisms and document microbial diversity of plant root systems compared with adjacent bulk soil. Results contribute data toward research on microbiome recruitment of weeds and other successful plants while addressing core topics in science education. PMID:27047592

Full Text Available As a diagnostic intervention (Bowles, Churchill, Effrat, & McDermott, 2002 for schools failing to meet school improvement goals, Ken-tucky used a scholastic audit process based on nine standards and 88 associated indicators called the Standards and Indicators for School Improvement (SISI. Schools are rated on a scale of 1–4 on each indicator, with a score of 3 considered as fully functional (Kentucky De-partment of Education [KDE], 2002. As part of enacting the legislation, KDE was required to also audit a random sample of schools that did meet school improvement goals; thereby identifying practices present in improving schools that are not present in those failing to improve. These practices were referred to as variance points, and were reported to school leaders annually. Variance points have differed from year to year, and the methodology used by KDE was unclear. Moreover, variance points were reported for all schools without differentiating based upon the level of school (elementary, middle, or high. In this study, we established a transparent methodology for variance point determination that differentiates between elementary, middle, and high schools.

This study tested the association between school-wide measures of an authoritative school climate and high school dropout rates in a statewide sample of 315 high schools. Regression models at the school level of analysis used teacher and student measures of disciplinary structure, student support, and academic expectations to predict overall high school dropout rates. Analyses controlled for school demographics of school enrollment size, percentage of low-income students, percentage of minority students, and urbanicity. Consistent with authoritative school climate theory, moderation analyses found that when students perceive their teachers as supportive, high academic expectations are associated with lower dropout rates.

Crouch, Ronald; Keys, Christopher B; McMahon, Susan D

2014-01-01

For students with disabilities, the process of school inclusion often begins with a move from segregated settings into general education classrooms. School transitions can be stressful as students adjust to a new environment. This study examines the adjustment of 133 students with and without disabilities who moved from a school that served primarily students with disabilities into 23 public schools in a large urban school district in the Midwest. These students and 111 of their teachers and other school staff rated the degree that students felt they belonged in their new schools and the quality of their social interactions. Results show that students who experienced more positive and fewer negative social interactions with school staff had higher school belonging. Teachers accurately noted whether students felt they belonged in their new settings, but were not consistently able to identify student perceptions of negative social interactions with staff. Implications for inclusion and improving our educational system are explored.

Researchers have analysed whether school and local knowledge complement or substitute each other, but have paid less attention to whether those two learning models use different cognitive strategies. In this study, we use data collected among three contemporary hunter-gatherer societies with relatively low levels of exposure to schooling yet with high levels of local ecological knowledge to test the association between i) schooling and ii) local ecological knowledge and verbal working memory. Participants include 94 people (24 Baka, 25 Punan, and 45 Tsimane') from whom we collected information on 1) schooling and school related skills (i.e., literacy and numeracy), 2) local knowledge and skills related to hunting and medicinal plants, and 3) working memory. To assess working memory, we applied a multi-trial free recall using words relevant to each cultural setting. People with and without schooling have similar levels of accurate and inaccurate recall, although they differ in their strategies to organize recall: people with schooling have higher results for serial clustering, suggesting better learning with repetition, whereas people without schooling have higher results for semantic clustering, suggesting they organize recall around semantically meaningful categories. Individual levels of local ecological knowledge are not related to accurate recall or organization recall, arguably due to overall high levels of local ecological knowledge. While schooling seems to favour some organization strategies this might come at the expense of some other organization strategies.

Design and performance of the constructed wetland wastewater treatment system at Phillips High School, Bear Creek, Alabama

Energy Technology Data Exchange (ETDEWEB)

1990-05-01

A constructed wetlands waste water treatment system has been constructed at Phillips High School, Bear Creek, Alabama, to polish the effluent from the school's extended aeration package treatment plant. The project is a demonstration of innovative technology under the Congressionally appropriated Bear Creek Floatway projects. Construction was completed in August 1988 at a cost of $36,266. Monitoring results for the period October 1988 through July 1989 reveal that the system has been very effective in polishing the effluent from the package treatment plant. The effectiveness is attributed primarily to maintenance of an overall oxidizing environment within the gravel substrate. Average monthly removals during the first year of operation exceeded 90 percent for BOD, TSS, organic nitrogen, total phosphorus, dissolved phosphorus, and fecal coliforms. Average removal percentages ranged in the 80s for ammonia and total nitrogen and in the 70s for nitrate + nitrite nitrogen and dissolved BOD. The prevalence of oxidizing conditions is probably the result of low carbonaceous demand, the low inlet hydraulic loading rate, and the combination of the shallow gravel depth and the excellent plant coverage and root depths during the first year of operation. 11 refs., 17 figs., 2 tabs.

Little Botany: A Mobile Game Utilizing Data Integration to Enhance Plant Science Education

Suphanut Jamonnak

2017-01-01

Full Text Available Mobile devices are rapidly becoming the new medium of educational and social life for young people, and hence mobile educational games have become an important mechanism for learning. To help school-aged children learn about the fascinating world of plants, we present a mobile educational game called Little Botany, where players can create their own virtual gardens in any location on earth. One unique feature of Little Botany is that the game is built upon real-world data by leveraging data integration mechanism. The gardens created in Little Botany are augmented with real-world location data and real-time weather data. More specifically, Little Botany is using real-time weather data for the garden location to simulate how the weather affects plants growth. Little Botany players can learn to select what crops to plant, maintain their own garden, watch crops to grow, tend the crops on a daily basis, and harvest them. With this game, users can also learn plant structure and three chemical reactions.

Violence in the School Setting: A School Nurse Perspective.

Science.gov (United States)

King, Kate K

2014-01-31

Violence in schools has become a significant public health risk and is not limited to violent acts committed in the school setting. Violence in homes, neighborhoods, and communities also affects the learning and behaviors of children while at school. School violence, such as shootings, weapons in schools, assaults, fights, bullying; other witnessed violence in non-school settings; and violence as a cultural norm of problem solving can all impact the ability of children to function in school. School nurses serve on the front-line of problem identification and intervene to diminish the effects of violence on both school children as individuals and on populations in schools and the community. This article describes ways in which school nurses deal with violence and concludes with discussion of potential responses to violence, including the school nurse response to violence and implications for other healthcare professionals.

Differences in school environment, school policy and actions regarding overweight prevention between Dutch schools. A nationwide survey

Buijs Goof

2010-01-01

Full Text Available Abstract Background Schools are regarded as an important setting for the prevention of overweight. This study presents a nationally representative picture of the obesogenity of the school environment, the awareness of schools regarding overweight, and actions taken by the schools aiming at overweight prevention. In addition, differences between school levels were studied. Methods In 2006-2007, questionnaires were sent to all Dutch secondary schools (age group 12-18 years. Prevalences of the outcome variables were calculated for the schools in total and by school level. The association between school level and outcome variables were analysed by a log linear regression. Results Unhealthy foods and drinks are widely available at secondary schools. One third of the schools indicated that overweight has increased among students and half of the schools agreed that schools were (coresponsible for the prevention of overweight. Only 3% of the schools have a policy on overweight prevention. Small differences were observed between vocational education schools and higher education schools. The presence of vending machines did not differ by school level, but at vocational education schools, the content of the vending machines was less healthy. Conclusion This study describes the current situation at schools which is essential for the development and evaluation of future overweight prevention policies and interventions. In general, secondary schools are not actively involved in overweight prevention and the nutritional environment at most schools could be improved. The small differences between school levels do not give reason for a differential approach for a certain school level for overweight prevention.

Full Text Available Science teachers are the main professionals in schools who address health-related subjects, though food and nutrition education (FNE projects are mainly planned by health professionals, especially nutritionists. The objective of this study is to create a transdisciplinary approximation between scientific research fields and practical fields from the analysis of an integrated case study conducted in Brazilian schools. In 2011, 10 days of observation were programmed in six schools in five cities. Semi-structured interviews were carried out with different social actors and data was analyzed using the complex thinking theory and the bricolage method of educational research. Planting of vegetable gardens or projects to improve table manners during mealtimes were identified in the schools. The results describe educational approaches used by science teachers to include FNE in school activities, even when not described in the official curriculum. Health professionals can identify actions to support health education in schools starting with that already undertaken by science teachers. The successful initiatives also involved professionals with practical knowledge and experience of life.

School achievement gaps and school failure are problematic issues in Latin America, and are mainly explained by the socio-economic status (SES) of the students. What schools can do to improve school achievement and reduce school failure is a critical issue, both for school management and teacher training. In this study, we present the association of individual and school-related socio-emotional variables with school achievement and performance, controlling for the effects of SES. A probabilistic sample of 4,964 students, drawn from 191 schools enrolled in year 10 in urban areas of Chile, answered questionnaires assessing subjective wellbeing, social wellbeing in school, school climate, school social wellbeing and students’ perceptions of teachers’ wellbeing. Using structural equation modeling, and controlling for SES, we modeled subjective wellbeing as a mediator of the relationship between school-related variables, such as school climate and perception of teacher’s wellbeing, and (a) school achievement, and (b) school performance. School achievement was computed as a product of (a) the probability of passing the school year, and (b) the percentage of yearly attendance at school. Data on school achievement was drawn from administrative registries from the Chilean Ministry of Education. School performance was computed as the estimated grade point average (GPA) at the end of the school year, based on the students’ previous 5-year GPAs, and was also obtained through administrative data of the last 5 years. Findings reveal the mediating role of subjective wellbeing in the relationship between school-related evaluations (students’ social wellbeing at school, their perception of teachers’ wellbeing and school climate) and school achievement. For school achievement, two variables were mediated (students’ social wellbeing at school and school climate). However, for school performance, no significant mediations were found.

Simulations and games are not new artifacts to the study of science in secondary school settings (Hug, Kriajcik and Marx 2005), however teachers remain skeptical as to their value, use and appropriateness (Rice 2006). The difficulty is not only the design and development of effective play environments that produce measurable changes in knowledge and/or understanding, but also in their on-the-ground use (Jaipal and Figg 2010). This paper reports on the use of a science-focused video game in five very different secondary school settings in Ontario, Canada. A mixed-methods approach was used in the study, and included data gathered on general gameplay habits and technology use, as well as informal interviews with teachers and students who played the game. In total, 161 participants played a series of games focused on the "life of a plant", and were given both a pre and post quiz to determine if the game helped them retain and/or change what they knew about scientific processes like plant cell anatomy and photosynthesis. Participants showed statistically significant improvement on quizzes that were taken after playing the game for approximately one-hour sessions, despite difficulties in some cases both accessing and playing the game for the full hour. Our findings also reveal the ongoing challenges in making use of technology in a variety of school sessions, even when using a browser-based game, that demanded very little other than a reliable internet connection.

Competition is a key process that determines plant community structure and dynamics, often mediated by nutrients and water availability. However, the role of soil microorganisms on plant competition, and the links between above- and belowground processes, are not well understood. Here we show that the effects of interspecific plant competition on plant performance are mediated by feedbacks between plants and soil bacterial communities. Each plant species selects a singular community of soil microorganisms in its rhizosphere with a specific species composition, abundance and activity. When two plant species interact, the resulting soil bacterial community matches that of the most competitive plant species, suggesting strong competitive interactions between soil bacterial communities as well. We propose a novel mechanism by which changes in belowground bacterial communities promoted by the most competitive plant species influence plant performance and competition outcome. These findings emphasise the strong links between plant and soil communities, paving the way to a better understanding of plant community dynamics and the effects of soil bacterial communities on ecosystem functioning and services.

Muckian, Jean; Snethen, Julia; Buseh, Aaron

School nurses provide health promotion and health services within schools, as healthy children have a greater potential for optimal learning. One of the school nurses' role is in encouraging healthy eating and increasing the availability of fruits and vegetables in the school. The purpose of this study was to explore and describe school nurses' perceptions of their role in promoting increased fruit and vegetable consumption in the school setting. One avenue to increased availability of fruits and vegetables in schools is Farm to School programs mandated by the Federal government to improve the health of school children. School nurses are optimally positioned to work with Farm to School programs to promote healthy eating. A secondary aim was to explore school nurses' knowledge, experiences and/or perceptions of the Farm to School program to promote fruit and vegetable consumption in the school setting. Three themes emerged from the focus groups: If There Were More of Me, I Could Do More; Food Environment in Schools; School Nurses Promote Health. School nurses reported that they addressed health issues more broadly in their roles as educator, collaborator, advocate and modeling healthy behaviors. Most of the participants knew of Farm to School programs, but only two school nurses worked in schools that participated in the program. Consequently, the participants reported having little or no experiences with the Farm to School programs. Copyright © 2017 Elsevier Inc. All rights reserved.

Logan, John R.; Burdick-Will, Julia

2015-01-01

Race, class, neighborhood, and school quality are all highly inter-related in the American educational system. In the last decade a new factor has come into play, the option of attending a charter school. We offer a comprehensive analysis of the disparities among public schools attended by white, black, Hispanic, Asian, and Native American children in 2010–2011, including all districts in which charter schools existed. We compare schools in terms of poverty concentration, racial composition, and standardized test scores, and we also examine how attending a charter or non-charter school affects these differences. Black and Hispanic (and to a lesser extent Native American and Asian) students attend elementary and high schools with higher rates of poverty than white students. Especially for whites and Asians, attending a charter school means lower exposure to poverty. Children’s own race and the poverty and charter status of their schools affect the test scores and racial isolation of schools that children attend in complex combinations. Most intriguing, attending a charter school means attending a better performing school in high-poverty areas but a lower performing school in low-poverty areas. Yet even in the best case the positive effect of attending a charter school only slightly offsets the disadvantages of black and Hispanic students. PMID:27616813

Apoplastic interactions between plants and plant root intruders

Kanako eMitsumasu

2015-08-01

Full Text Available Numerous pathogenic or parasitic organisms attack plant roots to obtain nutrients, and the apoplast including the plant cell wall is where the plant cell meets such organisms. Root-parasitic angiosperms and nematodes are two distinct types of plant root parasites but share some common features in their strategies for breaking into plant roots. Striga and Orobanche are obligate root parasitic angiosperms that cause devastating agricultural problems worldwide. Parasitic plants form an invasion organ called a haustorium, where plant cell wall degrading enzymes (PCWDEs are highly expressed. Plant-parasitic nematodes are another type of agriculturally important plant root parasite. These nematodes breach the plant cell walls by protruding a sclerotized stylet from which PCWDEs are secreted. Responding to such parasitic invasion, host plants activate their own defense responses against parasites. Endoparasitic nematodes secrete apoplastic effectors to modulate host immune responses and to facilitate the formation of a feeding site. Apoplastic communication between hosts and parasitic plants also contributes to their interaction. Parasitic plant germination stimulants, strigolactones (SLs, are recently identified apoplastic signals that are transmitted over long distances from biosynthetic sites to functioning sites. Here, we discuss recent advances in understanding the importance of apoplastic signals and cell walls for plant-parasite interactions.

Japanese government pronounced that the second step had been succeeded in the cooling down of the reactors on the middle of Dec 2011 at Fukushima-Daiichi nuclear power plant. In future, government aims to take out fuels from 4 reactors and shields their units. The nuclear power plants in Japan are gradually decreasing, because the checking for them has been performed and the permission of the re-start of them are difficult to be gained. On January 1st 2012, only 7 units are operating in Japan, though the about 54 units were set before the accident. At the end of December 2011, most radiations are emitted from cesium. The radioactivity in air and land around the plant was daily reported in newspaper. Government often gave the information about some RI-contamination in foods. They were taken off from the markets. At now stage, the most important project is the decontamination of radioactive materials from houses, schools, public facilities and industries. Government will newly classify three evacuation areas from April 2012. At the end of March, evacuees under 20 mSv/year possibly can go back their homes (evacuation-free area). The environmental doses will be depressed by decontamination under 10 mSv/year. At the range of 20-50 mSv, people will be controlled to live these area, they can go back their houses temporally (evacuation area). Over 50 mSv/year, however, people can go back house until 5 years at least (prohibited area). In new radiation limitation for a risk of human health, government made 100 mSv and 20 mSv for life span for one year, respectively. The aim of decontamination was set up to 10 mSv for 1 year and 5 mSv for next stage. A target at school is under1 mSv for children. Government accepted a new severe limitation per1 Kg at four groups; milk of baby (100 Bq) and milk (100 Bq), drinking water (10 Bq) and food (100 Bq).

Effects of knowledge and persuasion on high-school students' attitudes toward nuclear power plants

Science.gov (United States)

Showers, Dennis E.; Shrigley, Robert L.

Researchers report finding correlational data to identify a positive relationship between nuclear knowledge and positive attitudes toward the use of nuclear energy. This study investigated the relationship between nuclear knowledge and nuclear attitudes and to the understanding of Science-Technology-Society attitudes involving technological attitude objects. This quasi-experimental study tested the causal relationship between knowledge about nuclear power plants and attitudes toward their use in electrical generation. Subjects were presented with systematically designed communications developed to change either their knowledge about or attitude toward nuclear plants. The Standard Events of Instruction was the basis of the knowledge instruction, whereas the Learning Theory Approach and the Theory of Reasoned Action were the theoretical bases of the persuasive communication. The principal finding was that nuclear knowledge and nuclear attitude each can be changed independently of the other. Although knowledge and attitudes are correlationally linked, this study shows no evidence of a cause-effect relationship.Received: 4 May 1994; Revised: 14 July 1994;

Does decentralisation enhance a school's role of promoting social cohesion? Bosnian school leaders' perceptions of school governance

Science.gov (United States)

Komatsu, Taro

2014-05-01

This study seeks to understand whether and how decentralised school governance in Bosnia and Herzegovina (BiH) enhances the schools' role of promoting social cohesion. This includes increasing "horizontal" trust among different ethnic groups and "vertical" trust between civilians and public institutes. The study examined secondary school leaders' perceptions regarding school board influence on social cohesion policies and practices, their interactions with school board members, and their accountability to the school-based governing body. The results show that school leaders and school boards, supposedly representing the interests of local stakeholders, did not appear to be actively engaged in the deliberate process of promoting social cohesion. While school directors tended to view themselves as being independent from the school boards, ethnically diverse school boards provided important support to proactive school leaders for their inter-group activities. Given that the central level is not providing initiatives to promote social cohesion and that BiH citizens appear to generally support social cohesion, decentralised school governance has the potential to improve social trust from the bottom up. To promote participatory school governance, the study recommends that BiH school leaders should be provided with opportunities to re-examine and redefine their professional accountability and to assist local stakeholders to improve their involvement in school governance.

The influence of school culture and school climate on violence in schools of the Eastern Cape Province

Directory of Open Access Journals (Sweden)

Kalie Barnes

2012-01-01

Full Text Available This article reports on research undertaken about the influence of school culture and school climate on violence at schools in the Eastern Cape. An adapted California School Climate and Survey - Short Form (CSCSS-SF, which was used as the data-collection instrument, was completed by 900 Grade 10 to 12 learners. With the assistance of Pearson's product moment correlation coefficient, it was found that the better the school culture and school climate are at a school, the lower the levels of school violence. On the other hand, a lack of school safety contributed to learners experiencing higher levels of violence at schools. The results of hierarchy regression analyses indicated that school culture and school climate can be used to explain a significant percentage of variance in school violence. The f² values indicate that, with the exception of two aspects of the variance physical and verbal harassment, the results did not have any practical value. The article concludes with a few suggestions on how the results can be used to address school violence.

Chemical signaling between plants and plant-pathogenic bacteria.

Science.gov (United States)

Venturi, Vittorio; Fuqua, Clay

2013-01-01

Studies of chemical signaling between plants and bacteria in the past have been largely confined to two models: the rhizobial-legume symbiotic association and pathogenesis between agrobacteria and their host plants. Recent studies are beginning to provide evidence that many plant-associated bacteria undergo chemical signaling with the plant host via low-molecular-weight compounds. Plant-produced compounds interact with bacterial regulatory proteins that then affect gene expression. Similarly, bacterial quorum-sensing signals result in a range of functional responses in plants. This review attempts to highlight current knowledge in chemical signaling that takes place between pathogenic bacteria and plants. This chemical communication between plant and bacteria, also referred to as interkingdom signaling, will likely become a major research field in the future, as it allows the design of specific strategies to create plants that are resistant to plant pathogens.

Health promotion in Swedish schools: school managers' views.

Science.gov (United States)

Persson, Louise; Haraldsson, Katarina

2017-04-01

Schools are recognized worldwide as settings for health promotion, and leadership has a bearing on schools' ability to be health promoting. School managers have a great influence on what is prioritized in school, which in turn affects students' school performance and health. There is lack of research into school managers' views on health promotion, and what they consider to be central to health promotion. The aim was therefore to examine school managers' views about what health promotion in schools include. An explorative design, qualitative content analysis, was performed. In-depth interviews were conducted with all 13 school managers of a middle-sized municipality in central Sweden. The analysis had both manifest and latent content and three categories: 'Organization and Collaboration', 'Optimize the arena' and 'Strengthen the individual', and 10 subcategories emerged. The theme, 'Opportunities for learning and a good life', describes the latent content of these categories. Taking into account the views of school managers are important because these views help form a more complete picture of how school managers work with health promotion and what is needed to enhance health promotion to improve students' opportunities for learning and a good life. The Ottawa Charter for Health promotion is thereby transformed into practice. © The Author (2013). Published by Oxford University Press. All rights reserved.

Maltreated youth have higher rates of school dropout than their non-maltreated peers. School connectedness is a modifiable predictor of school success. We hypothesized maltreated youth's school connectedness (supportive relationships with adults at school and participation in school clubs) would be positively associated with high school graduation. We included youth with at least one Child Protective Services (CPS) report by age twelve from Longitudinal Studies of Child Abuse and Neglect, a prospective cohort study. Participation in extracurricular activities and adult relationships reported at age 16, high school graduation/General Education Development (GED) status reported at age 18, and demographics were provided by youth and caregivers. Maltreatment data were coded from CPS records. The outcome was graduation/receipt of GED. Multivariable logistic regressions examined the association between school connectedness and graduation/receipt of GED, controlling for confounders. In our sample of 318 maltreated youth, 73.3% graduated. School club was the only activity with a statistically significant association with graduation in bivariate analysis. Having supportive relationships with an adult at school was not significantly associated with graduation, though only 10.7% of youth reported this relationship. Maltreated youth who participated in school clubs had 2.54 times the odds of graduating, adjusted for study site, gender, poverty status, caregiver high school graduation status, and age at first CPS report (95% CI: [1.02, 6.33]). Few maltreated youth reported relationships with adults at school, and additional efforts may be needed to support these vulnerable youth. School club participation may represent an opportunity to modify maltreated youth's risk for school dropout. Copyright © 2017 Elsevier Ltd. All rights reserved.

School farming for school feeding: experiences from Nakuru, Kenya

Directory of Open Access Journals (Sweden)

Dick Foeken

2010-11-01

Full Text Available School feeding is an important development tool and is related to at least three Millennium Development Goals. School farming has been largely overlooked in the urban agriculture literature but with many parents nowadays unable to afford school lunches for their children, it can play a vital role in reducing the costs involved in providing nutritional meals for pupils. This paper examines school farming in an urban setting, namely Nakuru town, Kenya and looks at the current practice, the extent to which school farming contributes to school feeding programs, and the challenges it faces and how these can be overcome. Based on a survey done in almost all primary and secondary schools in Nakuru, it shows that school farming and school feeding are now common practice in the town and that in many cases school farming does indeed contribute to school feeding programs. However, much more is possible and the paper indicates how various constraints in terms of land, water, support and leadership might be overcome.

2013-07-01

Active transportation to school provides an important way for children to meet physical activity recommendations. The "walking school bus" (WSB) is a strategy whereby adults walk with a group of children to and from school along a fixed route. This study assessed whether school-organized WSB programs varied by school characteristics, district policies, and state laws. School data were gathered by mail-back surveys in nationally representative samples of U.S. public elementary schools during the 2008-2009 and 2009-2010 school years (n = 632 and 666, respectively). Corresponding district policies and state laws were obtained. Nationwide, 4.2% of schools organized a WSB program during 2008-2009, increasing to 6.2% by 2009-2010. Controlling for demographic covariates, schools were more likely to organize a WSB program where there was a strong district policy pertaining to safe active routes to school (OR = 2.14, P law requiring crossing guards around schools (OR = 2.72, P laws are associated with an increased likelihood of elementary schools organizing these programs. Policymaking efforts may encourage schools to promote active transportation.

Full Text Available An experiment was conducted at the CSIR-Crops Research Institute (CSIR-CRI Experimental station at Ejura in Ghana to compare the efficiency of four devices for planting no-till maize: Tractor drawn seeder, Chinese made jab planter, Locally made jab planter and a Cutlass. It took two (2 hours 48 minutes to plant one hectare of maize with the tractor drawn seeder, which was significantly (p less than 1% faster than all the planting methods. Cutlass was the slowest planting device lasting more than 14 hours per hectare. There was no significant difference in planting time between the Chinese planter and local planter. Economic analysis showed that cutlass planting produced the highest net benefit, whilst tractor drawn seeder produced the least benefit. In this study cutlass planting was done with precision by collaborating farmers. In actual farm situation however, hired laborers (planting gangs often plant in haste which often results in poor plant population leading to low yields. Tractor drawn seeders or jab planters could reduce drudgery in planting and encourage farm expansion.

Full Text Available Abstract Objectives This study examined associations between high school students' lunch patterns and vending machine purchases and the school food environment and policies. Methods A randomly selected sample of 1088 high school students from 20 schools completed surveys about their lunch practices and vending machine purchases. School food policies were assessed by principal and food director surveys. The number of vending machines and their hours of operation were assessed by trained research staff. Results Students at schools with open campus policies during lunchtime were significantly more likely to eat lunch at a fast food restaurant than students at schools with closed campus policies (0.7 days/week vs. 0.2 days/week, p Conclusion School food policies that decrease access to foods high in fats and sugars are associated with less frequent purchase of these items in school among high school students. Schools should examine their food-related policies and decrease access to foods that are low in nutrients and high in fats and sugars.

The training of operating personnel at Spanish nuclear power plant

International Nuclear Information System (INIS)

Diaz, Antonio Burgos

2011-01-01

An essential condition in order to ensure that nuclear power plants are operated reliably and safely is the availability in the Control Room of duly qualified persons capable both of preventing accidents and of responding to them should they occur. Training of the Control Room operating crews is accomplished in two major stages: a lengthy process of initial training in which the knowledge acquired at high school and university is built upon, leading to the specialisation required to appropriately carry out the tasks to be performed in the Control Room, and a continuous training program aimed at maintaining and improving the knowledge and skills required to operate the plant, with feedback of the lessons learned from the industry's operating experience. The use of full-scope simulators replicating the physical conditions and environment of the Control Room allows the period of initial training to be reduced and is the most appropriate method for the continuous training program of the control room personnel, since these simulators increase the realism of the training scenarios, help to better understand the response of the plant and provide an accurate idea of transient response times. Tecnatom is the Training Centre for Spanish Operators; it is the 'Operator Training Factory' and its mission is to train the nuclear power plant operating personnel in both technological fundamentals and the development of diagnostic skills through practical scenarios on the simulator and on-the-job training. Our training programmes are based on a SAT (Systematic Approach to Training) methodology that has been implemented at both Spanish and overseas plants. (author)

Torrens Armstrong, Anna M; McCormack Brown, Kelli R; Brindley, Roger; Coreil, Jeannine; McDermott, Robert J

2011-09-01

This study explored school personnel's perceptions of school refusal, as it has been described as a "common educational and public health problem" that is less tolerated due to increasing awareness of the potential socioeconomic consequences of this phenomenon. In-depth interviews were conducted with school personnel at the middle school (N = 42), high school (N = 40), and district levels (N = 10). The findings focus on emergent themes from interviews with school health personnel (N = 12), particularly those themes related to their perceptions of and role in working with school-refusing students. Personnel, especially school health services staff, constructed a typification of the school-refusing student as "the sick student," which conceptualized student refusal due to reasons related to illness. Personnel further delineated sick students by whether they considered the illness legitimate. School health personnel referenced the infamous "frequent fliers" and "school phobics" within this categorization of students. Overarching dynamics of this typification included parental control, parental awareness, student locus of control, blame, and victim status. These typifications influenced how personnel reacted to students they encountered, particularly in deciding which students need "help" versus "discipline," thus presenting implications for students and screening of students. Overall, findings suggest school health personnel play a pivotal role in screening students who are refusing school as well as keeping students in school, underscoring policy that supports an increased presence of school health personnel. Recommendations for school health, prevention, and early intervention include the development of screening protocols and staff training. © 2011, American School Health Association.

Plant aquaporins: roles in plant physiology.

Li, Guowei; Santoni, Véronique; Maurel, Christophe

2014-05-01

Aquaporins are membrane channels that facilitate the transport of water and small neutral molecules across biological membranes of most living organisms. Here, we present comprehensive insights made on plant aquaporins in recent years, pointing to their molecular and physiological specificities with respect to animal or microbial counterparts. In plants, aquaporins occur as multiple isoforms reflecting a high diversity of cellular localizations and various physiological substrates in addition to water. Of particular relevance for plants is the transport by aquaporins of dissolved gases such as carbon dioxide or metalloids such as boric or silicic acid. The mechanisms that determine the gating and subcellular localization of plant aquaporins are extensively studied. They allow aquaporin regulation in response to multiple environmental and hormonal stimuli. Thus, aquaporins play key roles in hydraulic regulation and nutrient transport in roots and leaves. They contribute to several plant growth and developmental processes such as seed germination or emergence of lateral roots. Plants with genetically altered aquaporin functions are now tested for their ability to improve plant resistance to stresses. This article is part of a Special Issue entitled Aquaporins.

Investigation of the modes of origin of attitudes concerning the risks of large-scale technical plants

International Nuclear Information System (INIS)

Gutmann, G.; Huschke, P.

1980-12-01

A hypothetical framework of the modes of origin of attitudes concerning the risks of large-scale industrial plants is developed. The hypotheses regarding the assessment of nuclear energy are empirically investigated in several schools, the pupils being between 14 and 16 years old. Results: 1. the ''polarity'' of opinion patterns on the problem of nuclear energy ''brought along'', i.e. already coined within the families could not be reversed by school instruction. 2. Instruction can possibly differentiate attitudes (assessments and cognitions). 3. Obviously the teaching style of the teacher is more determining for a differentiated attitude towards nuclear energy than the instruction material used. 4. A teaching style supporting and activating differentiation can be called partner-orientated and ''provocative'' and be considered as taking into consideration the communicative situations in school classes in a flexible manner. 5. On the other hand, a frontal and monologizing teaching style which does not respond to the changing communicative structures in school classes can block all interest and thus the possibility of influencing attitudes.

Kopas-Vukašinović Emina

2005-01-01

Full Text Available This longitudinal research started from the conclusion reached by different authors. According to them the time when a child leaves a pre-school institution to start primary school is marked by stagnation of and decrease in child’s creativity, seen as a personality potential. The aim of the research was to establish creativity levels shown by children in both pre-school institution and primary school, and then to conclude if difference between pre-school and school teachers` attitudes influence the development of a child’s creativity. Data was collected from a judgment scale given to pre-school and school teachers and arts creativity task given to children. It was concluded that the level of children’s creativity started to drop after they started primary school. Different understanding of the idea of creativity between pre-school and primary school teachers could be a possible reason leading to the phenomenon of decreasing creative expression in children starting primary school. On the basis of previous theoretical assumptions and the research results it is possible to define measures to be taken in view of teacher training, both at pre-school and primary school level. It is also important to check the validity of suggested measures in future research.

The Hindu temples of Lord Sri Laxminarasimha Swamy and Lord Hanuman, and the ethnic worship of mahua trees indicated it was a sacred grove which was selected as a Medicinal Plants Conservation Area. The exploration of Mallur Gutta resulted in the enumeration and documentation of plant wealth representing 470 species of 318 genera pertaining to 95 families of vascular plants. The importance of the grove as the residence for many rare or medicinal species in the state of Telangana is documented. The plant diversity is analyzed in terms of growth and life forms which indicate the prevailing microclimate, ecological opportunities and the species richness. The ecological services rendered by the Mallur Gutta forest ecosystem are documented to study how the great majority of the species are used by the ethnic and nonethnic people, and also the pilgrims who visit the shrine for its serenity. The study also identified two major threats to the conservation of hill ecosystem and the archeological site: 1 biotic pressure (the ever-increasing pilgrims, grazing by cattle, goat and sheep, the development activities taken up for the pilgrims, nondegradable litter thrown, collection of medicinal plants and widening of the pathway to the Chintamani perennial stream – the trampling and alien plant invasions of the marsh sustaining the stream; and 2 the potential for fire spreading from burning the litter.

The 'active school' model offers promise for promoting school-based physical activity (PA); however, few intervention trials have evaluated its effectiveness. Thus, our purpose was to: (1) describe Action Schools! BC (AS! BC) and its implementation (fidelity and feasibility) and (2) evaluate the impact of AS! BC on school provision of PA. Ten elementary schools were randomly assigned to one of the three conditions: Usual Practice (UP, three schools), Liaison (LS, four schools) or Champion (CS, three schools). Teachers in LS and CS schools received AS! BC training and resources but differed on the level of facilitation provided. UP schools continued with regular PA. Delivery of PA during the 11-month intervention was assessed with weekly Activity Logs and intervention fidelity and feasibility were assessed using Action Plans, workshop evaluations, teacher surveys and focus groups with administrators, teachers, parents and students. Physical activity delivered was significantly greater in LS (+67.4 min/week; 95% CI: 18.7-116.1) and CS (+55.2 min/week; 95% CI: 26.4-83.9) schools than UP schools. Analysis of Action Plans and Activity Logs showed fidelity to the model and moderate levels of compliance (75%). Teachers were highly satisfied with training and support. Benefits of AS! BC included positive changes in the children and school climate, including provision of resources, improved communication and program flexibility. These results support the use of the 'active school' model to positively alter the school environment. The AS! BC model was effective, providing more opportunities for "more children to be more active more often" and as such has the potential to provide health benefits to elementary school children.

Plant ecdysteroids: plant sterols with intriguing distributions, biological effects and relations to plant hormones.

Science.gov (United States)

Tarkowská, Danuše; Strnad, Miroslav

2016-09-01

The present review summarises current knowledge of phytoecdysteroids' biosynthesis, distribution within plants, biological importance and relations to plant hormones. Plant ecdysteroids (phytoecdysteroids) are natural polyhydroxylated compounds that have a four-ringed skeleton, usually composed of either 27 carbon atoms or 28-29 carbon atoms (biosynthetically derived from cholesterol or other plant sterols, respectively). Their physiological roles in plants have not yet been confirmed and their occurrence is not universal. Nevertheless, they are present at high concentrations in various plant species, including commonly consumed vegetables, and have a broad spectrum of pharmacological and medicinal properties in mammals, including hepatoprotective and hypoglycaemic effects, and anabolic effects on skeletal muscle, without androgenic side-effects. Furthermore, phytoecdysteroids can enhance stress resistance by promoting vitality and enhancing physical performance; thus, they are considered adaptogens. This review summarises current knowledge of phytoecdysteroids' biosynthesis, distribution within plants, biological importance and relations to plant hormones.

Plant toxicity, adaptive herbivory, and plant community dynamics

Feng, Z.; Liu, R.; DeAngelis, D.L.; Bryant, J.P.; Kielland, K.; Stuart, Chapin F.; Swihart, R.K.

We model effects of interspecific plant competition, herbivory, and a plant's toxic defenses against herbivores on vegetation dynamics. The model predicts that, when a generalist herbivore feeds in the absence of plant toxins, adaptive foraging generally increases the probability of coexistence of plant species populations, because the herbivore switches more of its effort to whichever plant species is more common and accessible. In contrast, toxin-determined selective herbivory can drive plant succession toward dominance by the more toxic species, as previously documented in boreal forests and prairies. When the toxin concentrations in different plant species are similar, but species have different toxins with nonadditive effects, herbivores tend to diversify foraging efforts to avoid high intakes of any one toxin. This diversification leads the herbivore to focus more feeding on the less common plant species. Thus, uncommon plants may experience depensatory mortality from herbivory, reducing local species diversity. The depensatory effect of herbivory may inhibit the invasion of other plant species that are more palatable or have different toxins. These predictions were tested and confirmed in the Alaskan boreal forest. ?? 2009 Springer Science+Business Media, LLC.

Experience with quality of training of personnel in start-up, operation and maintenance of nuclear power plants

International Nuclear Information System (INIS)

Ziman, V.; Alaxin, E.

1983-01-01

The theoretical education of personnel takes place in the branch training centre in Jaslovske Bohunice and in the concern training centre of the Slovak Power Plants. Practical training takes place in the Bohunice V-1 power plant. Selected specialists are trained in the training centre of the Novo Voronezh nuclear power plant, at the Paks nuclear plant and in the training centre of the Tusimice power plant. The recruitment, selection, schooling, practical training and placement of personnel and their assignment to posts is done in such a manner as to make sure that the complexly trained personnel is available 6 months to 3 years prior to the physical start-up of the nuclear power plant. The training of university graduates for the post of reactor operator takes 18 months or more. Trained personnel attend in-service training courses in form of complementary courses whose content includes such problems as the elimination of typified possible accidents, on the basis of the analysis of all failures which occurred in the previous period. The rising quality of personnel training at the Bohunice V-1 nuclear power plant is reflected in the decreasing number of failures caused by the human factor and in the increased availability of the power units.

Hood, Nancy E; Colabianchi, Natalie; Terry-McElrath, Yvonne M; O'Malley, Patrick M; Johnston, Lloyd D

2013-08-01

Since 2006-2007, education agencies (e.g., school districts) participating in U.S. federal meal programs are required to have wellness policies. To date, this is the only federal policy that addresses foods and beverages sold outside of school meals (in competitive venues). To examine the extent to which federally required components of school wellness policies are associated with availability of foods and beverages in competitive venues. Questionnaire data were collected in 2007-2008 through 2010-2011 school years from 892 middle and 1019 high schools in nationally representative samples. School administrators reported the extent to which schools had required wellness policy components (goals, nutrition guidelines, implementation plan/person responsible, stakeholder involvement) and healthier and less-healthy foods and beverages available in competitive venues. Analyses were conducted in 2012. About one third of students (31.8%) were in schools with all four wellness policy components. Predominantly white schools had higher wellness policy scores than other schools. After controlling for school characteristics, higher wellness policy scores were associated with higher availability of low-fat and whole-grain foods and lower availability of regular-fat/sugared foods in middle and high schools. In middle schools, higher scores also were associated with lower availability of 2%/whole milk. High schools with higher scores also had lower sugar-sweetened beverage availability and higher availability of 1%/nonfat milk, fruits/vegetables, and salad bars. Because they are associated with lower availability of less-healthy and higher availability of healthier foods and beverages in competitive venues, federally required components of school wellness policies should be encouraged in all schools.

The nature and structure of the school environment has the potential to shape children's health and well being. Few studies have explored the importance of school-level factors in explaining a child's likelihood of experiencing violence from school staff, particularly in low-resource settings such as Uganda. To quantify to what extent a student's risk of violence is determined by school-level factors we fitted multilevel logistic regression models to investigate associations and present between-school variance partition coefficients. School structural factors, academic and supportive environment are explored. 53% of students reported physical violence from staff. Only 6% of variation in students' experience of violence was due to differences between schools and half the variation was explained by the school-level factors modelled. Schools with a higher proportion of girls are associated with increased odds of physical violence from staff. Students in schools with a high level of student perceptions of school connectedness have a 36% reduced odds of experiencing physical violence from staff, but no other school-level factor was significantly associated. Our findings suggest that physical violence by school staff is widespread across different types of schools in this setting, but interventions that improve students' school connectedness should be considered. © The Author 2015.

Full Text Available Although investigation of school security measures and their relationships to various outcomes including school crime rates (Gottfredson, 2001, perpetuation of social inequality (Ferguson, 2001; Nolan, 2011; Welch & Payne, 2010, and the impact on childhood experiences has seen significant growth within the last 20 years (Newman, 2004; Kupchik, 2010, few studies have sought to explore the impacts of these measures on suspension rates. Using data from the Educational Longitudinal Study (2002, I explore the relationship between security measures and in-school, out-of-school, and overall suspension rates. Results indicate schools with a security officer experience higher rates of in-school suspensions but have no difference in rates of out-of-school or overall suspensions compared to schools without a security officer. No other measure of security was related to higher suspension rates. As prior literature suggests, schools with greater proportions of black students experienced significantly higher rates of all suspension types. Finally, different types of parental involvement correlated with both higher and lower suspension rates.

Written local wellness policies (LWPs) are mandated in school systems to enhance opportunities for healthy eating/activity. LWP effectiveness relies on school-level implementation. We examined factors associated with school-level LWP implementation. Hypothesized associations included system support for school-level implementation and having a school-level wellness team/school health council (SHC), with stronger associations among schools without disparity enrollment (majority African-American/Hispanic or low-income students). Online surveys were administered: 24 systems (support), 1349 schools (LWP implementation, perceived system support, SHC). The state provided school demographics. Analyses included multilevel multinomial logistic regression. Response rates were 100% (systems)/55.2% (schools). Among schools, 44.0% had SHCs, 22.6% majority (≥75%) African-American/Hispanic students, and 25.5% majority (≥75%) low-income (receiving free/reduced-price meals). LWP implementation (17-items) categorized as none = 36.3%, low (1-5 items) = 36.3%, high (6+ items) = 27.4%. In adjusted models, greater likelihood of LWP implementation was observed among schools with perceived system support (high versus none relative risk ratio, RRR = 1.63, CI: 1.49, 1.78; low versus none RRR = 1.26, CI: 1.18, 1.36) and SHCs (high versus none RRR = 6.8, CI: 4.07, 11.37; low versus none RRR = 2.24, CI: 1.48, 3.39). Disparity enrollment did not moderate associations (p > .05). Schools with perceived system support and SHCs had greater likelihood of LWP implementation, with no moderating effect of disparity enrollment. SHCs/support may overcome LWP implementation obstacles related to disparities. © 2016, American School Health Association.

[Development of Plant Metabolomics and Medicinal Plant Genomics].

Science.gov (United States)

Saito, Kazuki

2018-01-01

 A variety of chemicals produced by plants, often referred to as 'phytochemicals', have been used as medicines, food, fuels and industrial raw materials. Recent advances in the study of genomics and metabolomics in plant science have accelerated our understanding of the mechanisms, regulation and evolution of the biosynthesis of specialized plant products. We can now address such questions as how the metabolomic diversity of plants is originated at the levels of genome, and how we should apply this knowledge to drug discovery, industry and agriculture. Our research group has focused on metabolomics-based functional genomics over the last 15 years and we have developed a new research area called 'Phytochemical Genomics'. In this review, the development of a research platform for plant metabolomics is discussed first, to provide a better understanding of the chemical diversity of plants. Then, representative applications of metabolomics to functional genomics in a model plant, Arabidopsis thaliana, are described. The extension of integrated multi-omics analyses to non-model specialized plants, e.g., medicinal plants, is presented, including the identification of novel genes, metabolites and networks for the biosynthesis of flavonoids, alkaloids, sulfur-containing metabolites and terpenoids. Further, functional genomics studies on a variety of medicinal plants is presented. I also discuss future trends in pharmacognosy and related sciences.

School Climate as an Important Component in School Effectiveness

Dorina Rapti

2013-07-01

Full Text Available Expectations, values, faith, relationships with staff, the school leader, teachers and students behavior create school climate. The leader can promote or hinder a positive climate through his leadership model. The purpose of this study is to explore what are the climate types that appear in the school as well as to contribute to the expectations of different stakeholders on the school climate. The starting point for improving the performance of students and teachers is to improve school climate. Thus, this study will help leaders who for one reason or another have not been effective in keeping their responsibilities, and, as a result, did not work efficiently in improving school climate. It is assumed that a positive school climate enhances effective teaching, and as a result a better performance of student learning. This study will serve to further studies related to the expansion of the leaders’ roles on school climate. In conclusion, the research will assist policy makers in Albania to assess the content of the modules needed for training future managers and teachers to ensure they are equipped with the skills required to create a positive, open and collaborative climate in school. The school leader should be released from some managerial tasks, for paying more time to teachers and students.

There continues to be a need for increases in adult vaccination rates, especially among those working in environments which may easily become communicable disease outbreak centers, such as school employees in the school environment. The purpose of this study was to evaluate why rural Utah school employees were non-compliant with the influenza and measles, mumps, and rubella (MMR) vaccines, as well as to identify their views on mandatory vaccination policies. A questionnaire was distributed to all school employees in a rural Utah school district. Data analysis included frequencies and measures of central tendency and dispersion for quantitative items and theme identification for qualitative items. Only 51% of school employees were adequately vaccinated for influenza. Reasons for noncompliance with the influenza vaccine included inconvenience, lack of perceived need, and questionable vaccine efficacy. There were 39.3% school employees who had not received an MMR during adulthood, which was commonly attributed to lack of knowledge regarding the need for this vaccine. Almost half (45.7%) of school employees believed a mandatory vaccination policy should be instituted, although 24.2% of school employees were opposed to mandatory adult vaccination policies. Reasons for opposing vaccination mandates included violation of personal choice, lack of perceived vaccination safety and efficacy, lack of perceived need for adult vaccines, and vaccine cost. Suboptimal vaccination rates of school employees may negatively affect the health and well-being of individuals in the school environment. School employees report a variety of beliefs regarding the influenza and MMR vaccines. While over half of school employees support mandatory vaccination policies for adults working in the school environment, those opposing such a policy report concerns regarding violation of personal choice. Public health officials and school administrators should coordinate efforts to increase vaccination

Shaw, Jana; Tserenpuntsag, Boldtsetseg; McNutt, Louise-Anne; Halsey, Neal

2014-07-01

To compare medical, religious, and personal belief immunization exemption rates between private and public schools in US. Exemption rates were calculated using the Centers for Disease Control and Prevention School Immunization Assessment Surveys for the 2009-2010 school year excluding states with incomplete survey data. Standardized exemption rates weighted on enrollments in public and private schools were calculated. Differences in exemption rates between public and private schools were tested using Wilcoxon signed rank test. The overall state exemption rate was higher in US private than public schools, 4.25% (SD 4.27) vs 1.91% (1.67), P = .0001 and private schools had higher exemption rates for all types of exemptions; medical 0.58% (0.71) vs 0.34% (0.34) respectively (P = .0004), religious 2.09% (3.14) vs 0.83% (1.05) respectively (P = .0001), and personal belief 6.10% (4.12) vs 2.79% (1.57), respectively (P = .006). Overall exemption rates were significantly higher in states that allowed personal belief exemptions. Exemption rates were significantly higher in US private than in public schools. Children attending private schools may be at higher risk of vaccine-preventable diseases than public school children. Copyright © 2014 Elsevier Inc. All rights reserved.

PLANT BIOPRINTING: NOVEL PERSPECTIVE FOR PLANT BIOTECHNOLOGY

Directory of Open Access Journals (Sweden)

Adhityo WICAKSONO

2015-12-01

Full Text Available Bioprinting is a technical innovation that has revolutionized tissue engineering. Using conventional printer cartridges filled with cells as well as a suitable scaffold, major advances have been made in the biomedical field, and it is now possible to print skin, bones, blood vessels, and even organs. Unlike animal systems, the application of bioprinting in simple plant tissue cells is still in a nascent phase and has yet to be studied. One major advantage of plants is that all living parts are reprogrammable in the form of totipotent cells. Plant bioprinting may improve scientists’understanding of plant shape and morphogenesis, and could serve for the mass production of desired tissues or plants, or even the production of plant-based biomaterial for industrial uses. This perspectives paper explores these possibilities using knowledge on what is known about bioprinting in other biosystems.

Charter Schools and Student Compositions of Traditional Public Schools

Directory of Open Access Journals (Sweden)

Nevbahar Ertas

2013-06-01

Full Text Available One of the most contentious urban education policy issues in the United States today is the expansion of charter schools and its repercussions. Does the expansion of charter schools affect the racial and socioeconomic composition of traditional public schools in the United States? This study provides empirical evidence on this question by relying on a panel design that uses school-level data from two states that have experimented with charter schools for more than 15 years: Ohio and Texas. Using county-level, spatial, and enrollment-based measures of charter exposure, the changes from pre- to post-charter-legislation stages in the student compositions of public schools that do and do not face competition from charters are examined. The results suggest that charter school presence contributes to aggregate-level changes in the share of non-Hispanic White and free-lunch-eligible students in traditional public schools in both states in different ways.

Han, Ziqiang; Zhang, Guirong; Zhang, Haibo

2017-01-01

School violence and bullying in China is under investigated, though it has become a national concern recently. Using updated national representative survey data collected in 2016 from seven provinces across China, covering students from all pre-college school types (primary, middle, high and vocational schools), this paper analyzes the prevalence of school bullying and the correlation with several school attributes. The incidences of reported bullying, bullying others and witnessing bullying are 26.10%, 9.03% and 28.90%, respectively. Primary school students are more likely to be involved in bullying behaviors. Students from elite schools (leading schools) are also more likely to be involved. Relation with teachers, relation with peers and perceived academic achievement are protective factors. Being a boy is the only significant predictor of school bullying among the family and demographic characteristics used. The results highlight the importance of school climate on preventing school violence and bullying, and a whole-school intervention approach is needed for future intervention. PMID:28946682

School food in many countries has become the object of change and innovation processes, not only in relation to policies for healthier eating but also in relation to policies for more sustainable food consumption and procurement. The purpose of this study was to examine the possible influence that organic food sourcing policies in Danish school meal systems may have on the development of healthier school food environments. The study was a cross-sectional analysis undertaken among 179 school food coordinators (SFCs) through a web-based questionnaire (WBQ) in a sample of Danish public primary schools. The 'organic' schools were compared to 'non-organic' schools. The questionnaire explored the attitudes, intentions/policies and actions in relation to organic and healthy foods served in the schools. Data indicates that 20 'organic' schools were associated with the indicators of healthier school environments, including adopting a Food and Nutrition Policy (FNP) in the school (p = .032), recommending children to eat healthily (p = .004). The study suggests that organic food policies in schools may have potential to support a healthier school food environment.

Broussard, Lisa; Howat, Holly; Stokes, Billy; Street, Tanya

2011-01-01

The role of the State School Nurse Consultant has been well defined by the National Association of School Nurses. State School Nurse Consultants serve as a resource to school nurses on issues related to their practice, as well as a liaison between top-level educators and school nurses. The purpose of this article is to describe the role of the State School Nurse Consultant, and to present results of a survey of Louisiana school nurses related to their practice needs. A survey was administered via Survey Monkey to determine the perceived needs of Louisiana school nurses related to their professional practice. Eighty-eight members of the Louisiana School Nurse Organization participated in the online survey. Louisiana is 1 of 6 states that do not have a State School Nurse Consultant. Respondents to the survey indicated an overwhelming need to have a school nurse representative at the state level. Twenty-two of the respondents specifically stated that they would like to have a State School Nurse Consultant within the Department of Education. Budgetary constraints have resulted in a lack of funding for a State School Nurse Consultant in Louisiana. Partnerships with federally qualified health centers (FQHC) and billing of Medicaid for school nursing services are 2 examples of revenue sources for school nurses that Louisiana is investigating. Revenue from these sources may serve to supplement state funds so that this important resource for Louisiana school nurses can be put into place.

2014-05-01

State laws and farm-to-school programs (FTSPs) have the potential to increase fruit and vegetable (FV) availability in school meals. This study examined whether FV were more available in public elementary school lunches in states with a law requiring/encouraging FTSPs or with a locally grown-related law, and whether the relationship between state laws and FV availability could be explained by schools opting for FTSPs. A pooled, cross-sectional analysis linked a nationally representative sample of public elementary schools with state laws. A series of multivariate logistic regressions, controlling for school-level demographics were performed according to mediation analysis procedures for dichotomous outcomes. Roughly 50% of schools reported FV availability in school lunches on most days of the week. Schools with the highest FV availability (70.6%) were in states with laws and schools with FTSPs. State laws requiring/encouraging FTSPs were significantly associated with increased FV availability in schools and a significant percentage (13%) of this relationship was mediated by schools having FTSPs. Because state farm-to-school laws are associated with significantly higher FV availability in schools-through FTSPs, as well as independently-enacting more state legislation may facilitate increased FTSP participation by schools and increased FV availability in school meals. © 2014, American School Health Association.

Excluded from school: Autistic students’ experiences of school exclusion and subsequent re-integration into school

Directory of Open Access Journals (Sweden)

Janina Brede

2017-11-01

Full Text Available Background and aims All children have the right to receive an education and to be included in school. Yet young people on the autism spectrum, who are already vulnerable to poor health and social outcomes, are at increased risk of school exclusion. The current study sought to understand the key factors surrounding the school exclusion experiences of a group of autistic students with particularly complex needs, and their subsequent re-integration into education. Method We interviewed nine intellectually able students (eight male, one female; M age = 13.3 years, all with a diagnosis of autism and the majority with a history of demand avoidant behaviour. We also interviewed their parents and teaching staff about the students’ past and current school experiences. All students were currently being educated within an ‘Inclusive Learning Hub’, specially designed to re-integrate excluded, autistic students back into school, which was situated within a larger autism special school. Results Young people and their parents gave overwhelmingly negative accounts of the students’ previous school experiences. Children’s perceived unmet needs, as well as inappropriate approaches by previous school staff in dealing with children’s difficulties, were felt to cause decline in children’s mental health and behaviour and, ultimately, led to their exclusion from school. Four key factors for successful reintegration into school were identified, including (i making substantial adjustments to the physical environment, (ii promoting strong staff–student relationships, (iii understanding students’ specific needs, and (iv targeted efforts towards improving students’ wellbeing. Conclusion The culmination – and escalation – of challenges students experienced in the students’ previous placements could suggest that the educational journey to exclusion from school is an inevitable consequence for at least some autistic children, including those with

Plants can detect the presence of their neighbours and modify their growth behaviour accordingly. But the extent to which this neighbour detection is mediated by abiotic stressors is not well known. In this study we tested the acclimation response of Zea mays L. seedlings through belowground interactions to the presence of their siblings exposed to brief mechano stimuli. Maize seedling simultaneously shared the growth solution of touched plants or they were transferred to the growth solution of previously touched plants. We tested the growth preferences of newly germinated seedlings toward the growth solution of touched (T_solution) or untouched plants (C_solution). The primary root of the newly germinated seedlings grew significantly less towards T_solution than to C_solution. Plants transferred to T_solution allocated more biomass to shoots and less to roots. While plants that simultaneously shared their growth solution with the touched plants produced more biomass. Results show that plant responses to neighbours can be modified by aboveground abiotic stress to those neighbours and suggest that these modifications are mediated by belowground interactions.

2016-01-01

This study examined the availability of foods sold in vending machines and school stores in United States public and private schools, and associations of availability with students' food purchases and consumption. Descriptive analyses, chi-square tests, and Spearman product-moment correlations were conducted on data collected from 521 students aged 8 to 15 years recruited from orthodontic offices in California. Vending machines were more common in private schools than in public schools, whereas school stores were common in both private and public schools. The food items most commonly available in both vending machines and school stores in all schools were predominately foods of minimal nutritional value (FMNV). Participant report of availability of food items in vending machines and/or school stores was significantly correlated with (1) participant purchase of each item from those sources, except for energy drinks, milk, fruits, and vegetables; and (2) participants' friends' consumption of items at lunch, for 2 categories of FMNV (candy, cookies, or cake; soda or sports drinks). Despite the Child Nutrition and Women, Infants, and Children (WIC) Reauthorization Act of 2004, FMNV were still available in schools, and may be contributing to unhealthy dietary choices and ultimately to health risks. © 2015, American School Health Association.

Vitor Hugo Farina

2012-12-01

Full Text Available Volatile sulphur compounds (VSC are the gases mainly responsible for halitosis (bad breath. The aim of this research was to evaluate the effects of medicinal plants on halitosis control. Two commonly used plants were tested: Curcuma zedoaria and Camellia sinensis (green tea. These plants were prepared as an aqueous solution and used as mouthwashes, compared with a standard mouthwash of 0.12% chlorhexidine gluconate and a placebo (water. The experiment was conducted with 30 volunteers from the School of Dentistry of São Jose dos Campos, Univ. Estadual Paulista - UNESP, SP, Brazil. Each volunteer tested the four mouthwashes. The Cysteine Challenge Method, modified for this study, was used for initial breath standardization. Four breath assessments were conducted after volunteers rinsed orally with acetylcysteine: one before the test mouthwash was used; the second, one minute after its use; a third 90 minutes later; and the last 180 minutes later. The results showed that chlorhexidine gluconate lowered VSC production immediately, and that this effect lasted up to 3 hours, while the tested plants had immediate inhibitory effects but no residual inhibitory effects on VSC. We concluded that Curcuma zedoaria and Camellia sinensis, prepared as infusions and used as mouthwashes, did not have a residual neutralizing effect on VSC.

School-related stress and psychosomatic symptoms among school adolescents.

Science.gov (United States)

Natvig, G K; Albrektsen, G; Anderssen, N; Qvarnstrøm, U

1999-11-01

Associations between psychosomatic symptoms and school-induced stress, and personal and social resources were analyzed among 862 Norwegian adolescents ages 13-15 years participating in the WHO project, "Health Promoting Schools." Stress-related factors were represented by the average of scores of 3-12 items. Both in combined and separate analyses of each psychosomatic symptom, increasing school distress, the most direct measure of stress experience, was associated with increased risk. A similar relationship was found with school alienation, though not significant for all symptoms. Social support from the teacher decreased the risk among girls, whereas social support from other pupils reduced the risk among both genders, but in particular among boys. No consistent associations were seen between psychosomatic complaints and general or school-related self-efficacy or decision control. In some analyses, however, these factors seemed to modify the association with school distress or school alienation.

In such environment, safety is considered as the common objective for all activities throughout the plant lifecycle. One approach to achieve plant safety is to embed safety aspects within each function and activity within such environment. One ideal way to enable safety aspects within each automated function is through modeling. This paper proposes a theoretical approach to design plant safety model as integrated with the plant lifecycle model within such environment. Object-oriented modeling approach is used to construct the plant safety model using OO CASE tool on the basis of unified modeling language (UML). Multiple views are defined for plant objects to express static, dynamic, and functional semantics of these objects. Process safety aspects are mapped to each model element and inherited from design to operation stage, as it is naturally embedded within plant's objects. By developing and realizing the plant safety model, safer plant operation can be achieved and plant safety can be assured

Small School Reform

Directory of Open Access Journals (Sweden)

Carroll E. Bronson

2013-05-01

Full Text Available This qualitative ethnographic case study explored the evolution of a public urban high school in its 3rd year of small school reform. The study focused on how the high school proceeded from its initial concept, moving to a small school program, and emerging as a new small high school. Data collection included interviews, observations, and document review to develop a case study of one small high school sharing a multiplex building. The first key finding, “Too Many Pieces, Not Enough Glue,” revealed that the school had too many new programs starting at once and they lacked a clear understanding of their concept and vision for their new small school, training on the Montessori philosophies, teaching and learning in small schools, and how to operate within a teacher-cooperative model. The second key finding, “A Continuous Struggle,” revealed that the shared building space presented problems for teachers and students. District policies remain unchanged, resulting in staff and students resorting to activist approaches to get things done. These findings offer small school reform leaders suggestions for developing and sustaining a small school culture and cohesion despite the pressures to revert back to top-down, comprehensive high school norms.

2009-02-01

Full Text Available The aims in this research were to determine the perceptions of school climate held by educators of primary schools in the southern Cape. Six primary schools with a staff complement of 178 educators participated in the investigation. Two instruments were used: the Organisational Climate Description Questionnaire Rutgers Elementary (OCDQ-RE and Dimensions of Organisational Health Inventory of Elementary Schools (OHI-E. The results indicated that primary school educators in the southern Cape perceived their relations with their principals as closed, while educator-educator relations were perceived as more open. An engaged school climate was taken as the typical prototype for the relevant primary schools. Average health profiles were drawn for the overall organisational health of primary schools. A significant relationship was found between primary schools' perceptions of organisational climate and organisational health. A significant difference was found between perceptions held by educators from different primary schools regarding the various dimensions of organisational climate and health. These findings have significant implications for the implementation of change in schools, educators' job satisfaction, motivation, productivity, well-being, and learner achievement.

The study assessed the depth of school disaster safety at public elementary schools in Banda Aceh City, Indonesia in terms of comprehensive school safety, especially school location, disaster management and disaster education. The findings indicate that 56% of public elementary schools in Banda Aceh City are exposed to high tsunami risk, and most externally driven school disaster preparedness activities were not continued by the schools due to lack of ownership and funding. To realize comprehensive school safety, disaster preparedness programs should neither be brought in by external donors, nor be in a patchwork. Rather, it should be conducted jointly and sustainably by the local school and the community and supported by multi-sectoral support in the city. Comprehensive school safety of public elementary schools in Banda Aceh City could be realized by reviewing, updating and localizing school disaster preparedness programs by all the education partners in the city with strong political will and commitment.

Bottiani, Jessika H; Bradshaw, Catherine P; Mendelson, Tamar

2014-12-01

In response to persistent racial disparities in academic and behavioral outcomes between Black and White students, equitable school climate has drawn attention as a potential target for school reform. This study examined differences in Black and White students' experiences of school climate and explored whether indicators of school organizational health and staff burnout moderated differences in students' school experiences by race. Utilizing hierarchical linear modeling with a sample of 18,397 Black students (n=6228) and White students (n=12,169) and 2391 school staff in 53 schools, we found a consistent pattern of racial inequalities, such that Black students reported less positive experiences than White students across three indicators of school climate (caring γ=-0.08, porganizational health and student-reported school climate (e.g., staff affiliation and student-perceived equity, γ=0.07, porganizational health indicators were more strongly associated with positive perceptions of school climate among White students than Black students, translating into greater racial disparities in perceived school climate at schools with greater organizational health (e.g., supportive leadership by race on student-perceived engagement, γ=-0.03, p=.042). We also found negative associations between staff-reported burnout and students' experience of equity, such that the racial gap was smaller in schools with high ratings of burnout (γ=0.04, p=.002). These findings have implications for educators and education researchers interested in promoting school social contexts that equitably support student engagement and success.

Research suggests that school climate can have a great impact on student, teacher, and school outcomes. However, it is often assessed as a summary measure, without taking into account multiple perspectives (student, teacher, parent) or examining subdimensions within the broader construct. In this study, we assessed school climate from the perspective of students, staff, and parents within a large, urban school district using multilevel modeling techniques to examine within- and between-school variance. After adjusting for school-level demographic characteristics, students reported worse perceptions of safety and connectedness compared to both parent and staff ratings (all p climate ratings within a school. Understanding how perceptions differ between informants can inform interventions to improve perceptions and prevent adverse outcomes. PMID:28642631

Plant life management optimized utilization of existing nuclear power plants

International Nuclear Information System (INIS)

Watzinger, H.; Erve, M.

1999-01-01

For safe, reliable and economical nuclear power generation it is of central importance to understand, analyze and manage aging-related phenomena and to apply this information in the systematic utilization and as-necessary extension of the service life of components and systems. An operator's overall approach to aging and plant life management which also improves performance characteristics can help to optimize plant operating economy. In view of the deregulation of the power generation industry with its increased competition, nuclear power plants must today also increasingly provide for or maintain a high level of plant availability and low power generating costs. This is a difficult challenge even for the newest, most modern plants, and as plants age they can only remain competitive if a plant operator adopts a strategic approach which takes into account the various aging-related effects on a plant-wide basis. The significance of aging and plant life management for nuclear power plants becomes apparent when looking at their age: By the year 2000 roughly fifty of the world's 434 commercial nuclear power plants will have been in operation for thirty years or more. According to the International Atomic Energy Agency, as many as 110 plants will have reached the thirty-year service mark by the year 2005. In many countries human society does not push the construction of new nuclear power plants and presumably will not change mind within the next ten years. New construction licenses cannot be expected so that for economical and ecological reasons existing plants have to be operated unchallengeably. On the other hand the deregulation of the power production market is asking just now for analysis of plant life time to operate the plants at a high technical and economical level until new nuclear power plants can be licensed and constructed.

Described are training techniques used to prepare personnel for handling radioactive materials and specialized equipment. A plutonium recovery plant utilizes procedures, equipment, and facilities not normally found in other types of processing. New Chemical Process Operators require a high school degree or equivalent with no training or testing requirements, so training provides a basis for operators to work with various kinds of equipment. A Safety and Work Indoctrination Check Sheet is completed, and 12 major job assignments are studied in depth before new personnel are assigned to production shifts. The training techniques used are audio-visual intermixed with equipment displays, lectures, tours, and on-the-job training. The final goal is to advance operators in a three-year program, to prepare them for job assignments in a new plutonium recovery plant under construction, and for future environmental and energy programs which are being established

2008-12-01

This study investigates the relationship between chronic sleep reduction, functioning at school and school achievement of boys and girls. To establish individual consequences of chronic sleep reduction (tiredness, sleepiness, loss of energy and emotional instability) the Chronic Sleep Reduction Questionnaire has been developed. A total of 436 children (219 boys, 216 girls, 1 [corrected] missing; mean age = 11 years and 5 months) from the seventh and eight grades of 12 elementary schools participated in this study. The inter-item reliability (Cronbach's alpha = 0.84) and test-retest reliability (r = 0.78) of the Chronic Sleep Reduction Questionnaire were satisfactory. The construct validity of the questionnaire as measured by a confirmative factor analysis was acceptable as well (CMIN/DF = 1.49; CFI = 0.94; RMSEA = 0.034). Cronbach's alpha's of the scales measuring functioning at school (teacher's influence, self-image as pupil, and achievement motivation) were 0.69, 0.86 and 0.79. School achievement was based on self-reported marks concerning six school subjects. To test the models concerning the relations of chronic sleep reduction, functioning at school, and school achievement, the covariance matrix of these variables were analysed by means of structural equation modelling. To test for differences between boys and girls a multi-group model is used. The models representing the relations between chronic sleep reduction - school achievement and chronic sleep reduction - functioning at school - school achievement fitted the data quite well. The impact of chronic sleep reduction on school achievement and functioning at school appeared to be different for boys and girls. Based on the results of this study, it may be concluded that chronic sleep reduction may affect school achievement directly and indirectly via functioning at school, with worse school marks as a consequence.

Cooperation between pupils' parents and school nurses is an important part of health promotion in primary schools. Developing frank and trusting relationships contributes to easy and uninhibited cooperation. Cooperation between parents and school nurses has not been widely researched internationally. This article reports on parents' views on cooperation with school nurses in primary schools. The study aims at contributing to school nurses' work so that instead of focusing only on the children, family nursing approaches could be improved. Nineteen parents from 13 families from southern Finland were interviewed for the study in 2004. The data were analysed by grounded theory and the constant comparative method was utilized. Six concepts describing parents' views on cooperation were generated on the basis of the data. Cooperation consists of supporting the child's well-being. School nurses take children's and parents' concerns seriously and intervene effectively if the child's health is threatened. School nurses' expertise is not very visible within school communities. Hoping to receive information and desiring parental involvement are important concepts of cooperation with the school nurse. The child's family is not sufficiently known or taken holistically into consideration when the child's health is promoted. Parents are the initiators of cooperation within school health care and parents describe this by the concept of one-sided communication. Parents do not know about school nurses' work and school health services. They would like to be more involved in school nursing activities. When developing children's health services, parents' expertise in their children's well-being should be paid more attention. This study enhances the knowledge of family nursing by describing Finnish parents' perceptions of cooperation with school nurses. The findings facilitate the understanding of cooperation in school health services.

A high percentage of all sports injuries occur during school sports. It was analysed whether there are differences in frequency, nature and distribution of school sport injuries at two different types of schools. School sport injuries of all secondary modern schools (n = 106) and in lower classes of grammar Schools (n = 17) in the federal state of Tyrol, Austria, from the ten school years 2001/02 to 2010/11 were analysed. All physical injuries occurring during school sports and resulting in the consultation of a medical doctor and therefore being reported to the general accident department (Allgemeine Unfallversicherungsanstalt [AUVA]) were assessed. During the evaluation period an average number of 32,935 (±1584) school children attended the two types of schools in Tyrol per year. The average incidence of school sports injuries in this ten-year period in both types of schools was 36.4/1,000 (mean) with a standard deviation of 4.4/1,000 per school child per year. The incidence increased from 30.3 in the school year 2001/02 to 40.4 in the school year 2010/11 (r = 0.91; b = 1.34; p school sport injuries at secondary modern schools (37.4 ± 4.9 per 1,000 school children per year) was higher than at the lower classes of grammar schools (32.9 ± 4.0 per 1,000 school children per year; relative risk 1.138; 95% CI = 1.09-1.19; p = 1.8 × 10-8). In addition, the sports injuries of the school year 2010/11 were analysed in detail and a comparison was made between the two types of schools. The distribution pattern of school sports injuries did not show any significant differences between both school types. At the secondary modern schools, as well as in the lower classes of grammar schools, injuries to the upper extremities prevailed (>50%). Ball sports were responsible for every second injury. Secondary modern school pupils had a significantly higher risk of suffering a school sports injury than pupils in the lower classes of grammar schools. The injury pattern did not show

Dipping Strawberry Plants in Fungicides before Planting to Control Anthracnose

Directory of Open Access Journals (Sweden)

Full Text Available Anthracnose crown rot (ACR, caused by Colletotrichum fructicola, is a serious disease of strawberry in Korea. The primary inoculums of ACR were symptomless strawberry plants, plant debris, and other host plants. To effectively control anthracnose in symptomless transplanted strawberries, it is necessary to use diseasefree plants, detect the disease early, and apply a fungicide. Therefore, in 2010 and 2011, we evaluated the efficacy of pre-plant fungicide dips by using strawberry transplants infected by C. fructicola for the control of anthracnose. Dipping plants in prochloraz-Mn for 10 min before planting was most effective for controlling anthracnose in symptomless strawberry plants and resulted in more than 76% control efficacy. Azoxystrobin showed a control efficacy of over 40%, but plants treated with pyraclostrobin, mancozeb and iminoctadine tris showed high disease severity. The control efficacy of the dip treatment with prochloraz-Mn did not differ with temperature and time. Treatment with prochloraz-Mn for more than an hour caused growth suppression in strawberry plants. Therefore, the development of anthracnose can be effectively reduced by dipping strawberry plants for 10 min in prochloraz-Mn before planting.

Schools can promote healthy eating in adolescents. This study used a qualitative approach to examine barriers and facilitators to healthy eating in schools. Case studies were conducted with 8 low-income Michigan middle schools. Interviews were conducted with 1 administrator, the food service director, and 1 member of the coordinated school health team at each school. Barriers included budgetary constraints leading to low prioritization of health initiatives; availability of unhealthy competitive foods; and perceptions that students would not eat healthy foods. Schools had made improvements to foods and increased nutrition education. Support from administrators, teamwork among staff, and acknowledging student preferences facilitated positive changes. Schools with a key set of characteristics, (presence of a coordinated school health team, nutrition policies, and a school health champion) made more improvements. The set of key characteristics identified in successful schools may represent a school's health climate. While models of school climate have been utilized in the educational field in relation to academic outcomes, a health-specific model of school climate would be useful in guiding school health practitioners and researchers and may improve the effectiveness of interventions aimed at improving student dietary intake and other health behaviors. © 2014, American School Health Association.

Yoo, Yang Gyeong; Lee, In Soo

2013-01-01

Self-esteem and school adjustment of children in the lower grades of primary school, the beginning stage of school life, have a close relationship with development of personality, mental health and characters of children. Therefore, the present study aimed to verify the effect of school-based Maum Meditation program on children in the lower grades of primary school, as a personality education program. The result showed that the experimental group with application of Maum Meditation program had significant improvements in self-esteem and school adjustment, compared to the control group without the application. In conclusion, since the study provides significant evidence that the intervention of Maum Meditation program had positive effects on self-esteem and school adjustment of children in the early stage of primary school, it is suggested to actively employ Maum Meditation as a school-based meditation program for mental health promotion of children in the early school ages, the stage of formation of personalities and habits.

Plant species are important drivers of soil microbial communities. However, how plant functional traits are shaping these communities has received less attention though linking plant and microbial traits is crucial for better understanding plant-microbe interactions. Our objective was to determine how plant-microbe interactions were affected by plant traits. Specifically we analyzed how interactions between plant species and microbes involved in nitrogen cycling were affected by plant traits related to 'nitrogen nutrition in interaction with soil nitrogen availability. Eleven plant species, selected along an oligotrophic-nitrophilic gradient, were grown individually in a nitrogen-poor soil with two levels of nitrate availability. Plant traits for both carbon and nitrogen nutrition were measured and the genetic structure and abundance of rhizosphere. microbial communities, in particular the ammonia oxidizer and nitrate reducer guilds, were analyzed. The structure of the bacterial community in the rhizosphere differed significantly between plant species and these differences depended on nitrogen availability. The results suggest that the rate of nitrogen uptake per unit of root biomass and per day is a key plant trait, explaining why the effect of nitrogen availability on the structure of the bacterial community depends on the plant species. We also showed that the abundance of nitrate reducing bacteria always decreased with increasing nitrogen uptake per unit of root biomass per day, indicating that there was competition for nitrate between plants and nitrate reducing bacteria. This study demonstrates that nitrate-reducing microorganisms may be adversely affected by plants with a high nitrogen uptake rate. Our work puts forward the role of traits related to nitrogen in plant-microbe interactions, whereas carbon is commonly considered as the main driver. It also suggests that plant traits related to ecophysiological processes, such as nitrogen uptake rates, are more

1987-01-01

The necessary qualifications of the responsible personnel and the knowledge required by personnel otherwise employed in nuclear plants are among the requirements for licensing laid down in paragraph 7 of the German Atomic Energy Act. The formal regulations for nuclear power plants are not directly applicable to plants in the fuel cycle because of the differences in the technical processes and the plant and work organisation. The aim of the project was therefore to establish a possible need for regulations for the nuclear plants with respect to the qualification of the personnel, and to determine a starting point for the definition of the required qualifications. An extensive investigation was carried out in the Federal Republic of Germany into: the formal requirements for training; the plant and personnel organisation structures; the tasks carried out by the responsible and otherwise employed personnel; and the state of training. For this purpose plant owners and managers were interviewed and the literature and plant specific documentation (e.g. plant rules) were reviewed. On the basis of literature research, foreign practices were determined and used to make comparative evaluations. The status report is divided into three separate parts for the reprocessing, the uranium enrichment, and the manufacture of the fuel elements. On the basis of the situation for reprocessing plants (particularly that of the WAK) and fuel element manufacturing plants, the development of a common (not uniform) regulation for all the examined plants in the fuel cycle was recommended. The report gives concrete suggestions for the content of the regulations. (orig.) [de

Uncovering patterns of interest in useful plants. Frequency analysis of individual students’ interest types as a tool for planning botany teaching units

Full Text Available The paper presented examines how useful plants can help counteracting “plant blindness” – a phenomenon leading people to overlook plants in everyday-life. Recent research indicates that people are most likely interested in useful plants, hence this group of plants could be used to trigger interest in botanical content in general. This study has investigated the structure of interest in five subgroups of useful plants (medicinal plants, stimulant herbal drugs, spice plants, edible plants, and ornamental plants. For this purpose, the FEIN-questionnaire (Fragebogen zur Erhebung des Interesses an Nutzpflanzen = Questionnaire acquiring interest in useful plants was filled in by N = 1299 pupils from grade 5 to 12. Data analysis shows (for all age groups and both genders that medicinal plants and stimulant herbal drugs trigger high interest while spice plants, edible plants and ornamental plants raise only lower interest. However, mean values do not allow conclusions on individual level (e.g. in a school class. In order to gain information about the interest structure in a specific target group teachers deal with in practice, we have analysed the interests on individual level using frequency analysis of different interest types. Results show that stimulant herbal drugs seem to strongly polarize students, whereas medicinal plants are interesting for almost the whole sample. Eventually, medicinal plants turned out to be well suited to introduce botanical content by means of plants catching the interest of as many students as possible. Therefore, medicinal plants should be established as flagships counteracting plant blindness.

To assess whether alcohol, tobacco, and other drug (ATOD) use in elementary school may have serious implications for continued ATOD use in middle school and beyond. Longitudinal analyses were conducted on questionnaire data from 331 middle school students who had previously provided ATOD-use data during elementary school. Non-school personnel administered questionnaires in three participating school districts in three different states. The sample of students was ethnically and geographically diverse, including students from a range of low socioeconomic status backgrounds living in rural, urban or inner-city environments. Middle school alcohol use was almost three times as likely to occur if alcohol use had occurred in elementary school (OR = 2.94, p Elementary school use of tobacco and marijuana also greatly increased the likelihood of middle school use (OR = 5.35, p elementary school, during the middle childhood years.

Professional Burnout among School Counselors in Basic School

Directory of Open Access Journals (Sweden)

Jernej Kovač

2014-12-01

Full Text Available School counsellors are often stressed due to the nature of their work. This stress can, when unsatisfyingly treated, easily evolve to a professional burnout. In Slovenia no research with the specific aim to explore the professional burnout among school counsellors has been performed so far. Hence the aim of the present research is to compensate this shortage in the area of school counselling. The paper presents some theoretical foundations of occupational burnout and results of empirical research. The purpose of the empirical research was to determine the perceptions of occupational burnout among school counselors. We were interested in the level of occupational burnout and existing differences in terms of age, education and presence of supervision. We analysed the results of the present study according to three dimensions of occupational burnout in school counselors, namely lesser fulfilment, exhaustion and depersonalization. Results have shown that the perceived level of the avarage occupational burnout in most school counsellors is relatively homogenous. Within the individual dimensions of professional burnout among school counselors the sense of lesser fulfillment has proven to be the most strongly expressed. The study also showed that the greatest differences are seen in the dimension of lesser fulfilment and emotional exhaustion with regard to education and presence of supervision.

An Automated and Continuous Plant Weight Measurement System for Plant Factory.

Science.gov (United States)

Chen, Wei-Tai; Yeh, Yu-Hui F; Liu, Ting-Yu; Lin, Ta-Te

2016-01-01

In plant factories, plants are usually cultivated in nutrient solution under a controllable environment. Plant quality and growth are closely monitored and precisely controlled. For plant growth evaluation, plant weight is an important and commonly used indicator. Traditional plant weight measurements are destructive and laborious. In order to measure and record the plant weight during plant growth, an automated measurement system was designed and developed herein. The weight measurement system comprises a weight measurement device and an imaging system. The weight measurement device consists of a top disk, a bottom disk, a plant holder and a load cell. The load cell with a resolution of 0.1 g converts the plant weight on the plant holder disk to an analog electrical signal for a precise measurement. The top disk and bottom disk are designed to be durable for different plant sizes, so plant weight can be measured continuously throughout the whole growth period, without hindering plant growth. The results show that plant weights measured by the weight measurement device are highly correlated with the weights estimated by the stereo-vision imaging system; hence, plant weight can be measured by either method. The weight growth of selected vegetables growing in the National Taiwan University plant factory were monitored and measured using our automated plant growth weight measurement system. The experimental results demonstrate the functionality, stability and durability of this system. The information gathered by this weight system can be valuable and beneficial for hydroponic plants monitoring research and agricultural research applications.

Stiefel, Leanna; Elbel, Brian; Prescott, Melissa Pflugh; Aneja, Siddhartha; Schwartz, Amy Ellen

2016-01-01

BACKGROUND Public schools provide students with opportunities to participate in many discretionary, unmandated wellness programs. Little is known about the number of these programs, their distribution across schools, and the kinds of students served. We provide evidence on these questions for New York City (NYC) public schools. METHODS Data on wellness programs were collected from program websites, NYC’s Office of School Food and Wellness, and direct contact with program sponsors for 2013. Programs were grouped into categories, nutrition, fitness, and comprehensive, and were combined with data on school characteristics available from NYC’s Department of Education. Numbers of programs and provision of programs were analyzed for relationships with demographic and school structural characteristics, using descriptive statistics and multiple regression. RESULTS Discretionary wellness programs are numerous, at 18 programs. Little evidence supports inequity according to student race/ethnicity, income, or nativity, but high schools, new schools, co-located schools, small schools, and schools with larger proportions of inexperienced teachers are less likely to provide wellness programs. CONCLUSIONS Opportunities exist to further the reach of wellness programs in public schools by modifying them for high school adoption and building capacity in schools less likely to have the administrative support to house them.

The title's pun calls attention for two lines of work that characterize school pedagogy contemporary discussion. One of these lines is related to the last 15 years changing process at elementary school: it states that elementary school must be a learning and living place for children. The other line is related to movement pedagogy processes, which has been achieving higher and higher dimensions. Elementary school must be seen from movement point of view and must be transformed in a place for movement.

School lunch waste among middle school students: nutrients consumed and costs.

Cohen, Juliana F W; Richardson, Scott; Austin, S Bryn; Economos, Christina D; Rimm, Eric B

2013-02-01

The National School Lunch Program has been guided by modest nutrient standards, and the palatability of meals, which drives consumption, receives inadequate attention. School food waste can have important nutritional and cost implications for policymakers, students, and their families. Nutrient losses and economic costs associated with school meal waste were examined. The study also assessed if school foods served were valid proxies for foods consumed by students. Plate waste measurements were collected from middle school students in Boston attending two Chef Initiative schools (n=1609) and two control schools (n=1440) during a 2-year pilot study (2007-2009) in which a professional chef trained cafeteria staff to make healthier school meals. The costs associated with food waste were calculated and the percentage of foods consumed was compared with a gold standard of 85% consumption. Analyses were conducted in 2010-2011. Overall, students consumed less than the required/recommended levels of nutrients. An estimated $432,349 of food (26.1% of the total food budget) was discarded by middle school students annually at lunch in these Boston middle schools. For most meal components, substantially less than 85% was consumed. There is substantial food waste among middle school students in Boston. Overall, students' nutrient consumption levels were below school meal standards, and foods served were not valid proxies for foods consumed. The costs associated with discarded foods are high; if translated nationally for school lunches, roughly $1,238,846,400 annually is wasted. Students might benefit if additional focus were given to the quality and palatability of school meals. Copyright © 2013 American Journal of Preventive Medicine. Published by Elsevier Inc.

2017-01-01

Research carried out by me and my group over the last almost four decades are summarized here. The main emphasis of my work was and continues to be on plant physiology using radiation and radioisotopes. Plants live on water and inorganic elements. In the case of water, we developed neutron imaging methods and produced 15 O-labeled water (half-life 2 min) and applied them to understand water circulation pattern in the plant. In the case of elements, we developed neutron activation analysis methods to analyze a large number of plant tissues to follow element specific distribution. Then, we developed real-time imaging system using conventional radioisotopes for the macroscopic and microscopic observation of element movement. After the accident in Fukushima Daiichi nuclear power plant, we, the academic staff of Graduate School, have been studying agricultural effects of radioactive fallout; the main results are summarized in two books published by Springer.

This interdisciplinary study analyzes the production, circulation and reception of messages on climate change in secondary schools in France. The objective is to understand how political and educational policy initiatives influence the ways in which schools contribute to creating youngsters' perceptions and opinions about climate change. In order to study the conditions of production and reception of information about climate change, a survey was conducted in four French secondary schools, in the 'Bas Rhin' and 'Nord' departments, and local political actors in each department were interviewed. The cross disciplinary analytical and methodological approach uses the tools of sociological inquiry, information science, and political science: questionnaires and interviews were conducted with members of the educational and governmental communities of each school and department, semiotic and discursive analyses of corpuses of documents were carried out, in order to characterize documents used by students and teachers at school or in more informal contexts; the nature and extent of the relations between the political contexts and school directives and programs were also discussed. This interdisciplinary approach, combining sociological, communicational, and political methods, was chosen in response to the hypothesis that three types of variables (social, communicational and political) contribute to the structuring and production of messages about climate change in schools. This report offers a contextualized overview of activities developed within the four secondary schools to help sensitize children to the risks associated with climate change. A study of the networks of individuals (teachers, staff, members of associations, etc.) created in and around the school environment is presented. The degree of involvement of these actors in climate change programs is analyzed, as it is related to their motives and objectives, to the school discipline taught, and to the position

Full Text Available Abstract Background Research in plant science laboratories often involves usage of many different species, cultivars, ecotypes, mutants, alleles or transgenic lines. This creates a great challenge to keep track of the identity of experimental plants and stored samples or seeds. Results Here, we describe PlantDB – a Microsoft® Office Access database – with a user-friendly front-end for managing information relevant for experimental plants. PlantDB can hold information about plants of different species, cultivars or genetic composition. Introduction of a concise identifier system allows easy generation of pedigree trees. In addition, all information about any experimental plant – from growth conditions and dates over extracted samples such as RNA to files containing images of the plants – can be linked unequivocally. Conclusion We have been using PlantDB for several years in our laboratory and found that it greatly facilitates access to relevant information.

Perceptions of School Heads on Parents? Involvement on the Zimbabwean Primary Schools

OpenAIRE

THEMBINKOSI TSHABALALA

2013-01-01

The involvement of parents in Zimbabwean schools is governed by Statutory Instrument 87 of 1992 (SI87) for non-government schools and Statutory Instrument 379 of 1998 (SI379) (Bowora and Mpofu, 1998) for government schools. Non-government schools are run by School Development Committees (SDCs) and government schools are run by School Development Associations (SDAs). It is argued that comprehensive parent involvement is a pre-requisite for improving the culture of teaching and learning in scho...

Introduction to the Special Issue: Beyond traits: integrating behaviour into plant ecology and biology.

Cahill, James F

2015-10-26

The way that plants are conceptualized in the context of ecological understanding is changing. In one direction, a reductionist school is pulling plants apart into a list of measured 'traits', from which ecological function and outcomes of species interactions may be inferred. This special issue offers an alternative, and more holistic, view: that the ecological functions performed by a plant will be a consequence not only of their complement of traits but also of the ways in which their component parts are used in response to environmental and social conditions. This is the realm of behavioural ecology, a field that has greatly advanced our understanding of animal biology, ecology and evolution. Included in this special issue are 10 articles focussing not on the tried and true metaphor that plant growth is similar to animal movement, but instead on how application of principles from animal behaviour can improve our ability to understand plant biology and ecology. The goals are not to draw false parallels, nor to anthropomorphize plant biology, but instead to demonstrate how existing and robust theory based on fundamental principles can provide novel understanding for plants. Key to this approach is the recognition that behaviour and intelligence are not the same. Many organisms display complex behaviours despite a lack of cognition (as it is traditionally understood) or any hint of a nervous system. The applicability of behavioural concepts to plants is further enhanced with the realization that all organisms face the same harsh forces of natural selection in the context of finding resources, mates and coping with neighbours. As these ecological realities are often highly variable in space and time, it is not surprising that all organisms-even plants-exhibit complex behaviours to handle this variability. The articles included here address diverse topics in behavioural ecology, as applied to plants: general conceptual understanding, plant nutrient foraging, root

The "Generacion Diez" after-school program and Latino parent involvement with schools.

2005-11-01

The current study examines associations between participation in after-school programs and change in Latino parent involvement with schools. Hierarchical linear regression analyses demonstrated that parents of children who had higher after-school program attendance rates were significantly more likely to report increases in the quality of relationships with their children's teachers, frequency of parent-teacher contact, and engagement with their children's schooling over a two-year period. However, greater home educator contacts were related to decreases in quality and quantity of parent-school involvement. A primary implication is that attendance in school-based after-school programs may draw parents into children's regular-day school context. Editors' Strategic Implications The authors illustrate the promising practice of using after-school programs to promote parent involvement and to help integrate the often disparate family and school contexts for Latino children.

Many scientists, if not all, feel that their particular plant virus should appear in any list of the most important plant viruses. However, to our knowledge, no such list exists. The aim of this review was to survey all plant virologists with an association with Molecular Plant Pathology and ask them to nominate which plant viruses they would place in a 'Top 10' based on scientific/economic importance. The survey generated more than 250 votes from the international community, and allowed the generation of a Top 10 plant virus list for Molecular Plant Pathology. The Top 10 list includes, in rank order, (1) Tobacco mosaic virus, (2) Tomato spotted wilt virus, (3) Tomato yellow leaf curl virus, (4) Cucumber mosaic virus, (5) Potato virus Y, (6) Cauliflower mosaic virus, (7) African cassava mosaic virus, (8) Plum pox virus, (9) Brome mosaic virus and (10) Potato virus X, with honourable mentions for viruses just missing out on the Top 10, including Citrus tristeza virus, Barley yellow dwarf virus, Potato leafroll virus and Tomato bushy stunt virus. This review article presents a short review on each virus of the Top 10 list and its importance, with the intent of initiating discussion and debate amongst the plant virology community, as well as laying down a benchmark, as it will be interesting to see in future years how perceptions change and which viruses enter and leave the Top 10. © 2011 The Authors.
