The studies were performed on 825 school children (512 girls and 313 boys) from 1st and 2nd classes of secondary schools in som voievodship capital cities. 406 school children were from public, and 419 from non-public schools. The questionnaire prepared in the Institute for Children and Youngsters Institute in Berlin was used in this study. The evaluation of collected responses made possible to state the following conclusions: The organization of school and out school activities in public and non public schools was incorrect in several aspects ie. incorrect from the hygienic point of view organization of classes during day, too early beginning of the classes, too late ending of the classes in some week days, too long time needed to complete homework, and too late return to home after completing out school activities. The difficulties in homework completing were stated by school children from both public and non public schools. In 52% cases the parents helped in homework and 12% of children reported private lessons as an additional help in homework. The analysis of responses concerning frame of mind of school children showed better situation of pupils from non public schools. Only 15% of non public school children expressed reluctancy towards schools, as compared to 21% from public schools. The relationships between pupils and teachers did not worsened during consecutive years in non public schools, as opposite to public schools where the worsening of these relationships during the consecutive years was evident.

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.

Full Text Available Effect of gradual substitution of ordinary Portland cement by a few percent of silica fume (0.0, 2.5, 5.0 and 7.5 wt.% on the hydration properties of slag-Portland cement pastes up to 12 months was investigated. The results show that the composite cement pastes containing silica fume give the higher physico-mechanical properties than that of the slag-Portland cement. Also, the XRD results reveal that the peak of Ca(OH2 shows higher intensity in the sample without silica fume and completely disappears in the sample containing 7.5 wt.% silica fume content. Also, the intensity peaks of C4AH13 sharply increase with silica fume content.

DiPietro Mager, Natalie A; Ochs, Leslie; Ranelli, Paul L; Kahaleh, Abby A; Lahoz, Monina R; Patel, Radha V; Garza, Oscar W; Isaacs, Diana; Clark, Suzanne

To collect data on public health collaborations with schools of pharmacy, we sent a short electronic survey to accredited and preaccredited pharmacy programs in 2015. We categorized public health collaborations as working or partnering with local and/or state public health departments, local and/or state public health organizations, academic schools or programs of public health, and other public health collaborations. Of 134 schools, 65 responded (49% response rate). Forty-six (71%) responding institutions indicated collaborations with local and/or state public health departments, 34 (52%) with schools or programs of public health, and 24 (37%) with local and/or state public health organizations. Common themes of collaborations included educational programs, community outreach, research, and teaching in areas such as tobacco control, emergency preparedness, chronic disease, drug abuse, immunizations, and medication therapy management. Interdisciplinary public health collaborations with schools of pharmacy provide additional resources for ensuring the health of communities and expose student pharmacists to opportunities to use their training and abilities to affect public health. Examples of these partnerships may stimulate additional ideas for possible collaborations between public health organizations and schools of pharmacy.

Comparison of the physical and mechanical properties of MTA and portland cement.

Science.gov (United States)

Islam, Intekhab; Chng, Hui Kheng; Yap, Adrian U Jin

2006-03-01

This study evaluated and compared the pH, radiopacity, setting time, solubility, dimensional change, and compressive strength of ProRoot MTA (PMTA), ProRoot MTA (tooth colored formula) (WMTA), white Portland cement (WP), and ordinary Portland cement (OP). The results showed that PMTA and Portland cement have very similar physical properties. However, the radiopacity of Portland cement is much lower than that of PMTA. The compressive strength of PMTA was greater than Portland cement at 28 days. The major constituent of PMTA is Portland cement. Given the low cost of Portland cement and similar properties when compared to PMTA, it is reasonable to consider Portland cement as a possible substitute for PMTA in endodontic applications. However, industrially manufactured Portland cement is not approved currently for use in the United States and therefore no clinical recommendation can be made for its use in the human body. Further in vitro and in vivo tests, especially with regards its biocompatibility, should be conducted to ascertain if it meets the FDA requirements for use as a medical device.

2009-05-01

This study evaluated the radiopacity of Portland cement associated with the following radiopacifying agents: bismuth oxide, zinc oxide, lead oxide, bismuth subnitrate, bismuth carbonate, barium sulfate, iodoform, calcium tungstate, and zirconium oxide. A ratio of 20% radiopacifier and 80% white Portland cement by weight was used for analysis. Pure Portland cement and dentin served as controls. Cement/radiopacifier and dentin disc-shaped specimens were fabricated, and radiopacity testing was performed according to the ISO 6876/2001 standard for dental root sealing materials. Using Insight occlusal films, the specimens were radiographed near to a graduated aluminum stepwedge varying from 2 to 16 mm in thickness. The radiographs were digitized and radiopacity compared with the aluminum stepwedge using Digora software (Orion Corporation Soredex, Helsinki, Finland). The radiographic density data were converted into mmAl and analyzed statistically by analysis of variance and Tukey-Kramer test (alpha = 0.05). The radiopacity of pure Portland cement was significantly lower (p cement/radiopacifier mixtures were significantly more radiopaque than dentin and Portland cement alone (p cement/bismuth oxide and Portland cement/lead oxide presented the highest radiopacity values and differed significantly from the other materials (p cement/zinc oxide presented the lowest radiopacity values of all mixtures (p cement as radiopacifying agents. However, the possible interference of the radiopacifiers with the setting chemistry, biocompatibility, and physical properties of the Portland cement should be further investigated before any clinical recommendation can be done.

Markets & Myths: Autonomy in Public & Private Schools

Directory of Open Access Journals (Sweden)

Sandra Rubin Glass

1997-01-01

Full Text Available

School choice is the most controversial education policy issue of the 1990s. John Chubb and Terry Moe's Politics, Markets and America's Schools stimulated this investigation. They concluded that teacher and administrator autonomy was the most important influence on student achievement. They assumed that the organization of private schools offered greater autonomy resulting in higher student achievement and that the bureaucracy of public schools stifles autonomy limiting student achievement. The research undertaken here elaborates, elucidates, and fills in the framework of teacher and principal autonomy in public and private secondary schools. Interviews of more than thirty teachers and administrators in six high schools, observations, field notes, and analysis of documents collected in the field form the empirical base of this work. The sites included three private, independent, nondenominational secondary schools which are college preparatory and three public secondary schools noted for high graduation rates and offering numerous advanced placement courses.

The feelings expressed by both public and private school participants in this study testify to equally high degrees of autonomy. Issues that emerged from data analysis in this study which mitigate and shape autonomy include the following: conflicting and contradictory demands, shared beliefs, layers of protection, a system of laws, funding constraints and matters of size of the institution. These issues challenge oversimplified assertions that differences of any importance exist between the autonomy experienced by professionals in public and private high schools. This study reveals the complexity of the concept of autonomy and challenges the myth that teachers and principals in private schools enjoy autonomy and freedom from democratic bureaucracy that their public school counterparts do not.

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.

Understanding mineral trioxide aggregate/Portland-cement: a review of literature and background factors.

Science.gov (United States)

Steffen, R; van Waes, H

2009-06-01

This was to carry out a review of the literature concerning mineral trioxide aggregate (MTA) and Portland cement with regards to clinical, biological and mechanical findings and a possible substitution of MTA through Portland cement for endodontic use. Electronic literature search of scientific papers from January 1993 to January 2009 was carried out on the MEDLINE and Scopus databases using specific key words. In total, 57 papers were identified that dealt with MTA and Portland cement in a relevant way. The review of 50 papers conforming to the applied criteria showed that MTA and Portland cements have the same clinical, biological and mechanical properties. In animal experiments and technical characterisations both materials seemed to have very similar properties. The only difference is bismuth oxide in MTA added for better radio opacity. It seems likely that MTA materials are based on industrial Portland cements mixed with bismuth oxide. More studies, especially some long-term studies comparing MTA and Portland cement, are necessary. The existing literature gives a solid base for clinical studies with Portland cement in order to replace MTA as an endodontic material. Portland cement could be a substitute for most endodontic materials used in primary teeth.

Analyses of heavy metals in mineral trioxide aggregate and Portland cement.

Science.gov (United States)

Schembri, Matthew; Peplow, George; Camilleri, Josette

2010-07-01

Portland cement is used in the construction industry as a binder in concrete. It is manufactured from chalk, limestone, and clay, which are clinkered at very high temperatures and ground with gypsum to form Portland cement. The raw materials and the manufacturing process can result in the inclusion of heavy metals in Portland cement. Portland cement with a four to one addition of bismuth oxide is marketed as mineral trioxide aggregate (MTA), which is used mainly as a dental material. Heavy metal inclusion can be of concern because MTA is in contact with hard and soft tissues. Measurements of arsenic, lead, and chromium in hydrated gray and white Portland cement, ProRoot MTA, and MTA Angelus were conducted with graphite furnace atomic absorption spectrophotometry after acid digestion on the hydrated material. The leaching of the metal ions from the solid material in water and simulated body fluid (SBF) was also determined. All cement types showed high relative values of leached chromium compared with arsenic and lead in both the total metal content and leached species. The gray Portland cement showed the highest total amount of metal. The white Portland and both MTAs had lower values for all the leached metal ions. Both MTAs released more arsenic than the amount specified in ISO 9917-1 (2007). Portland cements and MTAs showed evidence of heavy metals in the acid-soluble form as well as leaching in deionized water and SBF. MTA contained levels of arsenic higher than the safe limit specified by the ISO 9917-1 (2007). Copyright 2010 American Association of Endodontists. Published by Elsevier Inc. All rights reserved.

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.

Thermophysical properties of blends from Portland and sulfoaluminate-belite cements

International Nuclear Information System (INIS)

Mojumdar, S.C.; Janotka, I.

2002-01-01

The behavior of mortars with blends consisting of sulfoaluminate-belite cements and ordinary Portland cement made with cement to sand ratio of 1:3 by weight and w/c = 0.5 maintained for 90 days at 20 0 C either at 60% relative humidity - dry air or 100% relative humidity - wet air. The results show insufficient character of hydraulic activity of sulfoaluminate-belite cements. Their quality has been improved. The replacement of 15 wt % of sulfoaluminate-belite cement by ordinary Portland cement influences strength positively and elasticity modulus values as well as hydrated phases and pore structure development of sulfoaluminate-belite/ordinary Portland cement blends relative to pure sulfoaluminate-belite cement systems. The above statements confirm the possible making technologies, when improvements in sulfoaluminate-belite cements quality will be achieved. One would then anticipate the competition in usages between sulfoaluminate-belite/ordinary Portland cement and blast furnace-slag Portland cement systems in the practice. It is important to consider because sulfoaluminate-belite cements are of great advantage from the viewpoint of energy savings and quantity of CO 2 released during their production. Thermal characteristics of the samples were studied by thermogravimetry and differential thermal analysis from room temperature to 1000 0 C in air atmosphere. Generally, four significant temperature regions on thermogravimetry curves with the respective differential thermal analysis peak temperature for all types of samples are observed (Authors)

The Social Acceptance of Community Solar: A Portland Case Study

Science.gov (United States)

Weaver, Anne

Community solar is a renewable energy practice that's been adopted by multiple U.S. states and is being considered by many more, including the state of Oregon. A recent senate bill in Oregon, called the "Clean Electricity and Coal Transition Plan", includes a provision that directs the Oregon Public Utility Commission to establish a community solar program for investor-owned utilities by late 2017. Thus, energy consumers in Portland will be offered participation in community solar projects in the near future. Community solar is a mechanism that allows ratepayers to experience both the costs and benefits of solar energy while also helping to offset the proportion of fossil-fuel generated electricity in utility grids, thus aiding climate change mitigation. For community solar to achieve market success in the residential sector of Portland, ratepayers of investor-owned utilities must socially accept this energy practice. The aim of this study was to forecast the potential social acceptance of community solar among Portland residents by measuring willingness to participate in these projects. Additionally, consumer characteristics, attitudes, awareness, and knowledge were captured to assess the influence of these factors on intent to enroll in community solar. The theory of planned behavior, as well as the social acceptance, diffusion of innovation, and dual-interest theories were frameworks used to inform the analysis of community solar adoption. These research objectives were addressed through a mixed-mode survey of Portland residents, using a stratified random sample of Portland neighborhoods to acquire a gradient of demographics. 330 questionnaires were completed, yielding a 34.2% response rate. Descriptive statistics, binomial logistic regression models, and mean willingness to pay were the analyses conducted to measure the influence of project factors and demographic characteristics on likelihood of community solar participation. Roughly 60% of respondents

EFL reading goals of grade 11 students across public and non-public schools in Addis Ababa, Ethiopia

Directory of Open Access Journals (Sweden)

Tekle Ferede

2017-09-01

Full Text Available This study investigated the EFL reading goals of Grade 11 students across public and non-public schools in the Ethiopian capital, Addis Ababa. To this end, quantitative data were collected from 556 (375 public and 181 non-public students via pre-tested structured questionnaire and analyzed into means, medians, standard deviations, ranges and Mann-Whitney U test scores. The results show that non-public school students were found better than public school students in possessing components of both extrinsic and intrinsic goals for reading. The notable exception in this regard is that public school students had higher social motivation for reading than their non-public school counterparts. Based on this finding, it has been concluded that non-public school students have a better chance of evolving as persistent self-initiated EFL readers since they have various goals which urge them to engage in reading a range of texts. It is thus recommended that English language teachers in public schools should constantly take actions to enable their students to develop appropriate EFL reading goals.

To assess periradicular lesions clinically and by computed tomography (CT) after endodontic surgery using either Portland cement or mineral trioxide aggregate (MTA) as a root-end filling material. Three patients diagnosed with periradicular lesions by cone-beam CT underwent endodontic surgery with root-end filling. Patient A was treated with MTA as the root-end filling material, patient B was treated with Portland cement and patient C had two teeth treated, one with MTA and the other with Portland cement. Six months after surgery, the patients were assessed clinically and by CT scan and the obtained results were compared. Periradicular tissue regeneration was observed in all cases, with no significant differences in bone formation when comparing the use of MTA and Portland cement as root-end filling materials. Both mineral trioxide aggregate and Portland cement were successful in the treatment of periradicular lesions.

2015-01-01

In this article, we compared the characteristics of public and private accredited public health training programs. We analyzed the distinct opportunities and challenges that publicly funded schools of public health face in preparing the nation’s public health workforce. Using our experience in creating a new, collaborative public school of public health in the nation’s largest urban public university system, we described efforts to use our public status and mission to develop new approaches to educating a workforce that meets the health needs of our region and contributes to the goal of reducing health inequalities. Finally, we considered policies that could protect and strengthen the distinct contributions that public schools of public health make to improving population health and reducing health inequalities.

Educating the future public health workforce: do schools of public health teach students about the private sector?

Science.gov (United States)

Rutkow, Lainie; Traub, Arielle; Howard, Rachel; Frattaroli, Shannon

2013-01-01

Recent surveys indicate that approximately 40% of graduates from schools of public health are employed within the private sector or have an employer charged with regulating the private sector. These data suggest that schools of public health should provide curricular opportunities for their students--the future public health workforce--to learn about the relationship between the private sector and the public's health. To identify opportunities for graduate students in schools of public health to select course work that educates them about the relationship between the private sector and public health. We systematically identified and analyzed data gathered from publicly available course titles and descriptions on the Web sites of accredited schools of public health. Data were collected in the United States. The sample consisted of accredited schools of public health. Descriptions of the number and types of courses that schools of public health offer about the private sector and identification of how course descriptions frame the private sector relative to public health. We identified 104 unique courses with content about the private sector's relationship to public health. More than 75% of accredited schools of public health offered at least 1 such course. Nearly 25% of identified courses focused exclusively on the health insurance industry. Qualitative analysis of the data revealed 5 frames used to describe the private sector, including its role as a stakeholder in the policy process. Schools of public health face a curricular gap, with relatively few course offerings that teach students about the relationship between the private sector and the public's health. By developing new courses or revising existing ones, schools of public health can expose the future public health workforce to the varied ways public health professionals interact with the private sector, and potentially influence students' career paths.

Lai, Yun-Kuang; Nadeau, Jessica; McNutt, Louise-Anne; Shaw, Jana

2014-12-12

School immunization requirements have ensured high vaccination rates and have helped to control vaccine-preventable diseases. However, vaccine exemptions have increased in the last decade. This study compared New York State private versus public schools with respect to medical and religious exemption rates. This retrospective study utilizes New York State Department of Health Immunization Survey data from the 2003 through 2012 academic years. Schools were categorized as private or public, the former further categorized by religious affiliation. Rates of medical and religious vaccine exemptions were compared by school category. From 2003 to 2012, religious exemptions increased in private and public schools from 0.63% to 1.35% and 0.17% to 0.29% (Spearman's R: 0.89 and 0.81), respectively. Among private schools, increases in religious exemption rates during the study period were observed in Catholic/Eastern Orthodox, Protestant/Other Christian, Jewish, and secular schools (Spearman's R=0.66, 0.99, 0.89, and 0.93), respectively. Exemption rate ratios in private schools compared to public schools were 1.39 (95% CI 1.15-1.68) for medical and 3.94 (95% CI: 3.20-4.86) for religious exemptions. Among private school students, all school types except for Catholic/Eastern Orthodox and Episcopal affiliates were more likely to report religious exemptions compared to children in public schools. Medical and religious exemption rates increased over time and higher rates were observed among New York State private schools compared to public schools. Low exemption rates are critical to minimize disease outbreaks in the schools and their community. Copyright © 2014 Elsevier Ltd. All rights reserved.

The aim of this study was to evaluate the response of rat subcutaneous tissue to Portland cement combined with two different radiopacifying agents, iodoform (CHI3) and zirconium oxide (ZrO2). These materials were placed in polyethylene tubes and implanted into the dorsal connective tissue of Wistar rats for 7 and 15 days. The specimens were then stained with hematoxylin and eosin, and inflammatory reaction parameters were evaluated by light microscopy. The intensity of the inflammatory response to the sealants was analyzed by two blind calibrated observers throughout the experimental period. Histological analysis showed that all the materials caused a moderated inflammatory reaction at 7 days, which then diminished with time. At 15 days, the inflammatory reaction was almost absent, and fibroblasts and collagen fibers were observed indicating normal tissue healing. The degrees of the inflammatory reaction on different days throughout the experimental period were compared using the non-parametric Kruskal-Wallis test. Statistical analysis demonstrated no significant differences amongst the groups, and Portland cement associated with radiopacifying agents gave satisfactory results. Therefore, Portland cement used in combination with radiopacifying agents can be considered a biocompatible material. Although our results are very encouraging, further studies are needed in order to establish safe clinical indications for Portland cement combined with radiopacifying agents.

Portland-pfa cement: a comparison between intergrinding and blending

Energy Technology Data Exchange (ETDEWEB)

Monk, M

1983-09-01

Portland-pfa cements containing 20-40% (by weight) pfa have been prepared in the laboratory both by intergrinding the ashes with clinker and by blending with cement. Cement properties have been assessed according to BS 4550 and scanning electron microscopy was used to examine the effects of grinding upon the pfa particles. The work has shown that intergrinding leads to an improvement in the water-reducing properties of coarse pfas and also in their pozzolanic activity as indicated by compressive strength development at later ages. Setting times have been found to be essentially the same for blended and interground cements, both being considerably longer than for typical ordinary Portland cements. Thus the results of this investigation indicate that, provided pfa's are chemically acceptable, they can be used for Portland-pfa cement manufacture by intergrinding irrespective of their coarseness.

Charters and foundations: are we losing control of our public schools?

Science.gov (United States)

Levine, Murray; Levine, Adeline

2014-01-01

From their inception, United States public schools have been subject to reform efforts. The most recent, and perhaps the most potent, is the current effort to establish charter schools as replacements for traditional public schools. They are supposed to be the analog of private schools, providing choices to parents, financed by public funds, but operating largely free of state and local regulations. The schools are organized under charters specified by state laws and authorized by public agencies. This essay traces the development and growth of charter schools and note changes in their original mission to improve public education. It concludes with the role that very wealthy foundations play in promoting charter schools. In effect, they control public education policy without real accountability to the public.

Racial and Economic Diversity in U.S. Public Montessori Schools

Directory of Open Access Journals (Sweden)

Mira Catherine Debs

2016-11-01

Full Text Available As public Montessori schools rapidly expand through the United States, the question then arises: What population of students do the schools serve? This study presents a new empirical data set examining the racial and economic diversity of 300 whole-school, public Montessori programs open in 2012–2013, where the entire school uses the Montessori Method. While school-choice scholars are concerned that choice programs like Montessori lead to greater student segregation by race and social class, this study finds a variety of outcomes for public Montessori. Public Montessori as a sector has strengths in student racial and socioeconomic diversity, but it also has diversity challenges, particularly among Montessori charters. The study concludes with recommended strategies for public Montessori schools to enroll a racially and economically diverse student body.

Stabilization of marlous soils with Portland cement will increase the service life of motor roads in areas where marl is used as a local road construction material. The result of the conducted research is the conclusion about the principal possibility of stabilization of marlous soils with Portland cement, and about the optimal percentage of the mineral part and the binding agent. When planning the experiment, a simplex-lattice plan was implemented, which makes it possible to obtain a mathematical model for changing the properties of a material in the form of polynomials of incomplete third order. Brands were determined for compressive strength according to GOST 23558-94 and variants of stabilized soils were proposed for road construction.

Automated external defibrillators (AEDs) have been used in the school setting to successfully resuscitate students, staff, and visitors. All public high schools in North Carolina have an AED. However, the number of North Carolina public middle schools with an AED is unknown. The purpose of this study was to determine the presence of AEDs at public middle schools in North Carolina and to estimate the cost associated with providing an AED to all public middle schools currently without one. All 547 middle schools in North Carolina's 117 public school systems were surveyed in 2009 via e-mail, fax, and, when necessary, telephone about whether an AED was present on site. For middle schools without AEDs, we estimated the cost of purchase and for 1 year of maintenance. A total 66.6% of public middle schools responded to 1 of 3 survey mailings. The remaining schools were contacted by telephone, so that 100% were included in data collection. At the time of the survey, at least 1 AED was present in 334 schools (61.1%). Of the 213 schools without AEDs, 57 (26.8%) were in school systems in which some middle schools had AEDs, and 156 (73.2%) were in systems in which no middle school had an AED. On the basis of a start-up cost of $1,200 per AED, the cost of providing an AED to each school without one is approximately $255,600. These data are based on self-report, and we could not verify whether AEDs were functional. Cost estimates do not include charges for ongoing maintenance and staff training. Two hundred and thirteen North Carolina public middle schools (38.9%) do not have an AED on site.

Recently, some studies have compared mineral trioxide aggregate (MTA) with Portland cements, concluding that the principal ingredients of Portland cements are similar to those of MTA. The purpose of the present study was to evaluate the effect of gray MTA, white MTA, and gray and white Portland cements on inflammatory cells in rats. Fresh mixtures mixed with distilled water were placed in polyethylene tubes, which were implanted in the dorsal subcutaneous connective tissue of 60 Sprague-Dawley rats along with empty tubes as controls. Tissue specimens were collected after the rats were sacrificed after 7, 15, 30, 60, and 90 days. The specimens were fixed, stained, processed, and histologically evaluated under a light microscope. Inflammatory reactions were classified as grade 0: without inflammatory cells, grade I: sporadic infiltration of inflammatory cells, grade II: moderate infiltration (125 cells). Data were analyzed with the nonparametric (two factor) analysis of variance and Kruskal-Wallis H-test. All the groups showed grade III inflammation after 7 and 15 days; there was a decrease in the inflammatory process after 30, 60, and 90 days. After 90 days, gray MTA, white MTA, and control groups had grade 0 inflammatory process, but gray Portland cement and white Portland cement groups showed grade 0 to grade I inflammatory processes. MTAs were more biocompatible; however, more studies are required. Copyright (c) 2010 American Association of Endodontists. Published by Elsevier Inc. All rights reserved.

Start Later, Sleep Later: School Start Times and Adolescent Sleep in Homeschool vs. Public/Private School Students

Science.gov (United States)

Meltzer, Lisa J.; Shaheed, Keisha; Ambler, Devon

2014-01-01

Homeschool students provide a naturalistic comparison group for later/flexible school start times. This study compared sleep patterns and sleep hygiene for homeschool students and public/private school students (grades 6-12). Public/private school students (n=245) and homeschool students (n=162) completed a survey about sleep patterns and sleep hygiene. Significant school group differences were found for weekday bedtime, wake time, and total sleep time, with homeschool students waking later and obtaining more sleep. Homeschool students had later school start times, waking at the same time that public/private school students were starting school. Public/private school students had poorer sleep hygiene practices, reporting more homework and use of technology in the hour before bed. Regardless of school type, technology in the bedroom was associated with shorter sleep duration. Later school start times may be a potential countermeasure for insufficient sleep in adolescents. Future studies should further examine the relationship between school start times and daytime outcomes, including academic performance, mood, and health. PMID:25315902

Synthesis of Portland cement and calcium sulfoaluminate-belite cement for sustainable development and performance

Science.gov (United States)

Chen, Irvin Allen

Portland cement concrete, the most widely used manufactured material in the world, is made primarily from water, mineral aggregates, and portland cement. The production of portland cement is energy intensive, accounting for 2% of primary energy consumption and 5% of industrial energy consumption globally. Moreover, portland cement manufacturing contributes significantly to greenhouse gases and accounts for 5% of the global CO2 emissions resulting from human activity. The primary objective of this research was to explore methods of reducing the environmental impact of cement production while maintaining or improving current performance standards. Two approaches were taken, (1) incorporation of waste materials in portland cement synthesis, and (2) optimization of an alternative environmental friendly binder, calcium sulfoaluminate-belite cement. These approaches can lead to less energy consumption, less emission of CO2, and more reuse of industrial waste materials for cement manufacturing. In the portland cement part of the research, portland cement clinkers conforming to the compositional specifications in ASTM C 150 for Type I cement were successfully synthesized from reagent-grade chemicals with 0% to 40% fly ash and 0% to 60% slag incorporation (with 10% intervals), 72.5% limestone with 27.5% fly ash, and 65% limestone with 35% slag. The synthesized portland cements had similar early-age hydration behavior to commercial portland cement. However, waste materials significantly affected cement phase formation. The C3S--C2S ratio decreased with increasing amounts of waste materials incorporated. These differences could have implications on proportioning of raw materials for cement production when using waste materials. In the calcium sulfoaluminate-belite cement part of the research, three calcium sulfoaluminate-belite cement clinkers with a range of phase compositions were successfully synthesized from reagent-grade chemicals. The synthesized calcium sulfoaluminate

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.

Stakeholders Involvement in Performance Management in Public General Schools

Directory of Open Access Journals (Sweden)

Kristi Ploom

2013-01-01

Full Text Available In response to increasing concerns with the legitimacy and efficiency of public spending, performance management as a part of world-wide public sector reform, called New Public Management (NPM has taken place. This is also the case of educational sector. In Estonian education system, legislation formally enables to design an integrated performance management system. But there is few research done to investigate how these policies and regulations ought to be put into force in order to gain the benefits considering the schools' and pupils' better performance. This study investigates how different stakeholders are involved into the performance management in Estonian general schools. The study is based on empirical survey data gathered from 303 schools providing secondary education in Estonia. The research findings have three main implications. Firstly, the paper contributes to the scarce knowledge about implementation of performance management issues in public schools. Our analysis revealed that compilation of school development plans in Estonian schools is rather a formal obligation. Therefore we propose that the analysis and discussion of the school development plans is needed to organize on regional level, involving all main stakeholders of a school. Secondly, we suggest that in the circumstances of a decentralised education system, like in Estonia, it is needed to implement, central practical performance assessment principles and guidance for the schools. Thirdly, it is highly necessary to improve schools’ cooperation with different stakeholder groups. Also the framework involving different stakeholder groups in the decentralized schools management system should be built up.

Slow progress in changing the school food environment: nationally representative results from public and private elementary schools.

Science.gov (United States)

Turner, Lindsey; Chaloupka, Frank J

2012-09-01

Children spend much of their day in school, and authorities have called for improvements in the school food environment. However, it is not known whether changes have occurred since the federal wellness policy mandate took effect in 2006-2007. We examined whether the school food environment in public and private elementary schools changed over time and examined variations by school type and geographic division. Survey data were gathered from respondents at nationally representative samples of elementary schools during the 2006-2007 and 2009-2010 school years (respectively, 578 and 680 public schools, and 259 and 313 private schools). Topics assessed included competitive foods, school meals, and other food-related practices (eg, school gardens and nutrition education). A 16-item food environment summary score was computed, with possible scores ranging from 0 (least healthy) to 100 (healthiest). Multivariate regression models were used to examine changes over time in the total school food environment score and component items, and variations by US census division. Many practices improved, such as participation in school gardens or farm-to-school programs, and availability of whole grains and only lower-fat milks in lunches. Although the school food environment score increased significantly, the magnitude of change was small; as of 2009-2010 the average score was 53.5 for public schools (vs 50.1 in 2006-2007) and 42.2 for private schools (vs 37.2 in 2006-2007). Scores were higher in public schools than in private schools (Pschool size. For public schools, scores were higher in the Pacific and West South Central divisions compared with the national average. Changes in the school food environment have been minimal, with much room remaining for improvement. Additional policy changes may be needed to speed the pace of improvement.

Globally the number of children reaching school age is estimated to be 1.2 billion children (18% of the world's population) and rising. This study was therefore designed to determine the school health services available and its practices in primary schools in Ogun state, Western Nigeria. The study was a comparative cross-sectional survey of private and public primary schools in Ogun state using a multi-stage sampling technique. Participants were interviewed using a structured, interviewer administered questionnaire and a checklist. Data collected was analyzed using the SPSS version 15.0. A total of 360 head teachers served as respondents for the study with the overall mean age of 45.7 ± 9.9 years. More than three quarters of the respondents in both groups could not correctly define the school health programme. There were no health personnel or a trained first aider in 86 (47.8%) public and 110 (61.1%) private schools but a nurse/midwife was present in 57 (31.7%) and 27 (15.0%) public and private schools. (χ(2) = 17.122, P = 0.002). In about 95% of the schools, the teacher carried out routine inspection of the pupils while periodic medical examination for staff and pupils was carried out in only 13 (7.2%) public and 31 (17.2%) private schools (χ(2) = 8.398, P = 0.004). A sick bay/clinic was present in 26 (14.4%) and 67 (37.2%) public and private schools respectively (χ(2) = 24.371, P = 0.001). The practice of school health programme was dependent on the age (χ(2) = 12.53, P = 0.006) and the ethnicity of the respondents (χ(2) = 6.330, P = 0.042). Using multivariate analysis only one variable (type of school) was found to be a predictor of school health programme. (OR 4.55, CI 1.918-10.79). The study concludes that the practice of the various components of school health services was poor but better in private primary schools in Nigeria. Routine inspection by teachers was the commonest form of health appraisal. This may suggest that more health personnel need to

Utilization of Iron Ore Tailings as Raw Material for Portland Cement Clinker Production

Directory of Open Access Journals (Sweden)

Li Luo

2016-01-01

Full Text Available The cement industry has for some time been seeking alternative raw material for the Portland cement clinker production. The aim of this research was to investigate the possibility of utilizing iron ore tailings (IOT to replace clay as alumina-silicate raw material for the production of Portland cement clinker. For this purpose, two kinds of clinkers were prepared: one was prepared by IOT; the other was prepared by clay as a reference. The reactivity and burnability of raw meal, mineralogical composition and physical properties of clinker, and hydration characteristic of cement were studied by burnability analysis, differential thermal analysis, X-ray diffraction, and hydration analysis. The results showed that the raw meal containing IOT had higher reactivity and burnability than the raw meal containing clay, and the use of IOT did not affect the formation of characteristic mineralogical phases of Portland cement clinker. Furthermore, the physical and mechanical performance of two cement clinkers were similar. In addition, the use of IOT was found to improve the grindability of clinker and lower the hydration heat of Portland cement. These findings suggest that IOT can replace the clay as alumina-silicate raw material for the preparation of Portland cement clinker.

Modelling porewater chemistry in hydrated Portland cement

International Nuclear Information System (INIS)

Berner, U.R.

1987-01-01

Extensive employment of concrete is foreseen in radioactive waste repositories. A prerequisite for modelling the interactions between concrete and formation waters is characterization of the concrete system. Available experimental data from high pressure squeezing of cement pore-water indicate that, besides the high pH due to alkali hydroxide dissolution, cement composition itself influences the solubility determining solid phases. A model which simulates the hydration of Portland cement assuming complete hydration of the main clinker minerals is presented. The model also includes parameters describing the reactions between the cement and blending agents. Comparison with measured pore-water data generally gives a consistent picture and, as expected, the model gives correct predictions for pure Portland cements. For blended cements, the required additional parameters can, to some extent, be derived from pore-water analysis. 14 references, 1 figure, 4 tables

Factors of School Effectiveness and Performance of Selected Public and Private Elementary Schools: Implications on Educational Planning in the Philippines

2017-02-01

Full Text Available What defines effective school is the necessity of the school community to tailor interventions to improve quality of education. This study determined the factors of school effectiveness and level of school performance of private and public elementary schools in the Second Congressional District of Cagayan Province, Philippines. The study made use of mixed-method research. For quantitative, the descriptive correlational method was used to identify the relationship between school effectiveness and school performance. Factorial analysis was also used to identify the principal components of school effectiveness of private and public elementary schools. The participants of the study were the 182 public and private elementary school principals and teachers from the 20 sampled schools. School effectiveness was measured using the seven correlates of effective schools. On the other hand, the level of school performance was gauged through the National Achievement Test (NAT results for the past three years. The qualitative part of the study focused on the school effectiveness practices and NAT practices of selected private and public elementary schools. The findings of the study revealed that the level of school effectiveness of both private and public elementary schools was excellent. However, test of difference showed that public schools exhibited stronger home-school relations than the private schools. In terms of the level of school performance, public schools perform better than the private schools for the past three years. Significantly, there exists a strong positive relationship between school effectiveness and school performance. The factorial analysis revealed that among all the correlates of school effectiveness, school leadership competency and professional collaboration influenced the performance of both schools. Recommendations of the study can help the government and school officials to plan appropriate strategies in improving the quality of

Violence is universal; it occurs in schools (both public and private). The study aim was to assess the rates of violence as well as existing violence prevention strategies in public and private schools in Osun state. A cross sectional study was conducted among 800 secondary school students (599 in public and 201 in private schools) selected by multistage sampling technique using quantitative and qualitative methods of data collection. The mean age for all the respondents was 14.26 years +/- 2.001 Males make up about 51% of the respondents in both public and private schools. Respondents from public schools assaulted other students and staff with a weapon more than their colleagues in private schools (24.7% and 9.7% against 12.9% and 6.5% respectively). The commonest violence 'prevention' strategy in both schools was punishment for violent acts (>90%). Respondents in public schools perpetrated and experienced virtually all forms of school-related violence more than those in private, schools. There were mild differences in existing violence prevention strategies in both schools. School connectedness seems to be a major factor in the differential rates of violence between both groups of schools.

Rethinking schools of public health: a strategic alliance model.

Science.gov (United States)

Moloughney, Brent W; Skinner, Harvey A

2006-01-01

Canada is in the midst of rejuvenation of public health organizations, mandates and infrastructure. Major planning exercises are underway regarding public health human resources, where academic institutions have a key role to play. To what extent could schools of public health be part of the solution? Many universities across Canada are considering or in the process of implementing MPH programs (some 17 programs planned and/or underway) and possible schools of public health. However, concerns are raised about critical mass, quality and standards. We encourage innovation and debate about ways to enhance collaborative and structural arrangements for education programs. A school of public health model might emerge from this, but so too might other models. Also, novel types of organizational structure need consideration. One example is a "strategic alliance" model that is broad-based, integrative and adaptive--building on the interdisciplinary focus needed for addressing public health concerns in the 21st century. From our perspective, the central question is: what (new) types of organizational structures and, equally important, collaborative networks will enable Canada to strengthen its public health workforce so that it may better address local and global challenges to public health?

School superintendents' perceptions of schools assisting students in obtaining public health insurance.

Science.gov (United States)

Rickard, Megan L; Price, James H; Telljohann, Susan K; Dake, Joseph A; Fink, Brian N

2011-12-01

Superintendents' perceptions regarding the effect of health insurance status on academics, the role schools should play in the process of obtaining health insurance, and the benefits/barriers to assisting students in enrolling in health insurance were surveyed. Superintendents' basic knowledge of health insurance, the link between health and learning, and specific school system practices for assisting students were also examined. A 4-page questionnaire was sent to a national random sample of public school superintendents using a 4-wave postal mailing. Only 19% of school districts assessed the health insurance status of students. School districts' assistance in helping enroll students in health insurance was assessed using Stages of Change theory; 36% of superintendents' school districts were in the action or maintenance stages. The schools most often made health insurance materials available to parents (53%). The perceived benefits identified by more than 80% of superintendents were to keep students healthier, reduce the number of students with untreated health problems, reduce school absenteeism, and improvement of students' attention/concentration during school. The 2 most common perceived barriers identified by at least 50% of superintendents were not having enough staff or financial resources. Most superintendents believed schools should play a role in helping students obtain health insurance, but the specific role was unclear. Three fourths of superintendents indicated overwhelmingly positive beliefs regarding the effects of health insurance status on students' health and academic outcomes. School personnel and public policy makers can use the results to support collaboration in getting students enrolled in health insurance. © 2011, American School Health Association.

2013-04-01

The purpose of this study was to assess parental perceptions of the current state of care for children with diabetes in the Alabama public school system, identify existing disparities, and determine what resources would most improve diabetes management in this setting. There is a significant need for such information because of the paucity of published data on the current state of diabetes care in Alabama public schools. We based our survey on the American Diabetes Association guidelines and collected responses on the Internet via SurveyMonkey and by paper surveys. We distributed surveys to parents of children with diabetes through the Children's Hospital endocrinology clinic, a diabetes camp, and through the Alabama Association of School Nurses e-mail listserv. A majority of children had type 1 diabetes mellitus. Students who could conveniently check their blood glucose levels (BGLs) at school were significantly more likely to participate in all school activities and their parents were significantly more likely to be satisfied with their child's diabetes care at school. Compared with minority students (defined as all races other than white), white students were more likely to be able to conveniently check their BGLs at school. The accommodation and care for children with diabetes is highly variable within much of the Alabama public school system. The ability to conveniently check BGLs at school is key for participation in all school activities and for parental satisfaction with diabetes care at school. Institution of a uniform, statewide diabetes training protocol for school personnel could improve care and parental satisfaction.

Hospital waste ashes in Portland cement mortars

International Nuclear Information System (INIS)

Genazzini, C.; Zerbino, R.; Ronco, A.; Batic, O.; Giaccio, G.

2003-01-01

Nowadays, most concretes incorporate mineral additions such as pozzolans, fly ash, silica fume, blast furnace slag, and calcareous filler among others. Although the technological and economical benefits were the main reasons for the use of mineral additions, the prevention of environmental contamination by means of proper waste disposal becomes a priority. The chance of incorporating hospital waste ashes in Portland cement-based materials is presented here. Ash characterization was performed by chemical analysis, X-ray diffraction, radioactive material detection, and fineness and density tests. Conduction calorimetry and setting time tests were developed on pastes including ash contents from 0% to 100%. Mortars were prepared including ash contents up to 50% of cement. The results of setting time, temperature development, flexural and compressive strengths, water absorption, density, and leachability are analyzed. Results indicate that Portland cement systems could become an alternative for the disposal of this type of ashes

Full Text Available This study aims to examine public and private school teachers’ opinions on different aspects of their professional associations and provisions and also asks principals about teachers’ conduct and their views on the Nigerian curriculum. To conduct this study, qualitative and quantitative research models were used to investigate differences between the two organizations. Quantitative data was collected by distributing questionnaires to 118 teachers in the Abuja Municipal Area Council (AMAC, Nigeria. To conduct the qualitative analysis, 15 teachers from two schools were selected (a total of 30 teachers to answer 5 discussion questions concerning their views on the Nigerian educational system. The findings revealed that private school teachers are at an advantage when it comes to provision of resources and technology, professional development and to some degree salaries. Both public and private school teachers felt being a teacher did not bring them respect in their community. Government policy makers need to study private schools and how they operate to see how they can make changes to produce the revolutionary reform needed in education. 30 principals’ interviews revealed that public school teachers are not easily held accountable for misconduct due to the structure of leadership, while private school teachers are held accountable and any form of unprofessionalism easily leads to termination of employment.

The objective of this study is to analyze the pozzolanic activity of red ceramic residue on the partial replacement of Portland cement in mortars. The mortars were prepared by substituting 25% of the Portland cement for ground of ceramic residue with water cement’s factor of 0.48. The concrete used to construct the reference mortars and those with addiction was CPII-Z-32 (compound of Portland pozzolana cement). The chemical analysis and physical ceramic waste showed that this meets the requirements of NBR12653 (2014) for use as pozzolanic material. The pozzolanic activity index (IAP) obtained for the ceramic waste to twenty-eight days cure rate was 80.28%. (author)

Reder, Sheri; Quan, Linda

2003-03-01

To determine the best approaches for increasing cardiopulmonary resuscitation (CPR) training opportunities for public high school students, we conducted a statewide survey of all 310 public high schools in Washington State. The findings describe CPR student training currently provided by high schools, barriers to providing, and strategies to increase CPR training of high school students. The response rate was 89% (276 schools) from a combination of mail and telephone surveys; 35% (n=97) reported that they did not provide any CPR student training. Of the 132 schools that provided CPR student training, 23% trained less than 10% of their students, and 39% trained more than 90% of their students. The majority of public high schools, 70%, did not have any teacher trained to teach CPR or had only one teacher with such training. Yet 80% of schools felt that CPR training is best provided in school settings. Schools perceived the greatest benefit of CPR training as providing students with the skill to save a life (43%). The most frequently identified barriers were logistical: limited time to teach the curriculum (24%), lack of funds (16%), and instructor scheduling difficulties (17%). Less than 5% of respondents voiced any opposition to CPR training, and that opposition was for logistical reasons. To increase CPR training, the single best strategies suggested were: increase funding, provide time in the curriculum, have more certified instructors, and make CPR student training a requirement.

The purpose of this study is to evaluate the ultimate compressive strength of 50% and 25% Portland cement mixed with Polymer-reinforced zinc oxide eugenol and zinc oxide eugenol cement after 1 hour, 24 hours, and 7 days. One hundred and eighty samples were selected. The samples were made cylindrical of size 6 × 8 mm and were divided into six groups as follows with each group consisting of 10 samples. Group 1: Polymer-reinforced zinc oxide eugenol with 50% Portland cement (PMZNPC 50%) Group 2: Polymer-reinforced zinc oxide eugenol with 25% Portland cement (PMZNPC 25%) Group 3: Polymer-reinforced zinc oxide eugenol with 0% Portland cement (PMZNPC 0%) Group 4: Zinc oxide eugenol with 50% Portland cement (ZNPC 50%) Group 5: Zinc oxide eugenol with 25% Portland cement (ZNPC 25%) Group 6: Zinc oxide eugenol with 0% Portland cement (ZNPC 0%) These samples were further subdivided based on time interval and were tested at 1 hour, 24 hours and at 7 th day. After each period of time all the specimens were tested by vertical CVR loaded frame with capacity of 5 tones/0473-10kan National Physical laboratory, New Delhi and the results were statistically analyzed using ANOVA and Scheffe test. Polymer-reinforced cement with 50% Portland cement, Zinc oxide with 50% Portland cement, Polymer-reinforced cement with 25% Portland cement and Zinc oxide with 25% Portland cement exhibited higher compressive strength when compared to Zinc oxide with 0% Portland cement and Polymer-reinforced cement with 0% Portland cement, at different periods of time. The difference between these two groups were statistically significant (P Portland cement in Zinc oxide eugenol and Polymer-modified zinc oxide cement can be used as core build up material and permanent filling material. It is concluded that 50% and 25% Portland cement in zinc oxide eugenol and polymer-modified zinc oxide eugenol results in higher compressive strength and hence can be used as permanent filling material and core built

Authors of the most recent study of athletic training (AT) services have suggested that only 42% of secondary schools have access to athletic trainers. However, this study was limited by a small sample size and was conducted more than 10 years ago. To determine current AT services in public secondary schools. Cross-sectional study. Public secondary schools in the United States. A total of 8509 (57%) of 14,951 secondary schools from all 50 states and Washington, DC, responded to the survey. Data on AT services were collected for individual states, National Athletic Trainers' Association districts, and the nation. Of the 8509 schools that responded, 70% (n = 5930) had AT services, including full-time (n = 3145, 37%), part-time (n = 2619, 31%), and per diem (n = 199, 2%) AT services, and 27% (n = 2299) had AT services from a hospital or physical therapy clinic. A total of 4075 of 8509 schools (48%) provided coverage at all sports practices. Eighty-six percent (2,394,284/2,787,595) of athletes had access to AT services. Since the last national survey, access to AT services increased such that 70% of respondent public secondary schools provided athletic trainers at sports games or practices. Approximately one-third of all public secondary schools had full-time athletic trainers. This number must increase further to provide appropriate medical coverage at athletic practices and games for secondary school athletes.

2010-01-01

Cement-based piezoelectric composites have attracted great attention recently due to their promising applications as sensors in smart structures. Lead zirconate titanate (PZT) and Portland cement (PC) composite were fabricated using 60% of PZT by volume. Scanning Electron Microscope and piezoresponse force microscope were used to investigate the morphology and domain configurations at the interfacial zone of PZT-Portland cement composites. Angular PZT ceramic grains were found to bind well with the cement matrix. The submicro-scale domains were clearly observed by piezoresponse force microscope at the interfacial regions between the piezoelectric PZT phase and Portland cement phase, and are clearer than the images obtained for pure PZT. This is thought to be due to the applied internal stress of cement to the PZT ceramic particle which resulted to clearer images.

Hwang, Yun-Chan; Lee, Song-Hee; Hwang, In-Nam; Kang, In-Chol; Kim, Min-Seok; Kim, Sun-Hun; Son, Ho-Hyun; Oh, Won-Mann

2009-03-01

This study compared the chemical constitution, radiopacity, and biocompatibility of Portland cement containing bismuth oxide (experimental cement) with those of Portland cement and mineral trioxide aggregate (MTA). The chemical constitution of materials was determined by scanning electron microscopy and energy-dispersive X-ray analysis. The radiopacity of the materials was determined using the ISO/6876 method. The biocompatibility of the materials was tested by MTT assay and tissue reaction. The constitution of all materials was similar. However, the Portland cement and experimental cement were more irregular and had a larger particle size than MTA. The radiopacity of the experimental cement was similar to MTA. The MTT assay revealed MTA to have slightly higher cell viability than the other materials. However, there were no statistically significant differences between the materials, with the exception of MTA at 24 h. There was no significant difference in the tissue reaction between the experimental groups. These results suggest that the experimental cement may be used as a substitute for MTA.

Full Text Available Avalia-se, neste trabalho, a potencialidade do uso da metacaolinita e dos resíduos de produção de tijolos cerâmicos queimados finamente moídos, como substitutos parciais do cimento Portland. Os materiais foram caracterizados física, química e mineralogicamente, além de determinado o índice de atividade pozolânica com cimento Portland. A evolução da resistência a compressão e a flexão das argamassas foi avaliada até as idades de, respectivamente, 365 e 208 dias. As porcentagens de substituição do cimento Portland, em peso, pelos materiais pozolânicos, variaram de 20 a 50%, enquanto o fator água/cimento variou de 0,37 a 0,45. Os resultados obtidos indicaram que a metacaolinita e o tijolo moído queimado possuem elevada atividade pozolânica e que a resistência a compressão, aos 28 dias, das argamassas mistas, foi superior à das argamassas de cimento Portland para os níveis de substituição e fatores água/cimento estudados. Um modelo matemático para predição da resistência à compressão das argamassas mistas é proposto com base em um desenho fatorial de experimentos.This paper evaluates the potentiality of metakaolin and crushed waste fired clay brick as cement replacement materials. They were characterised physically, chemically and mineralogically and their activity with Portland cement determined. The influence of the partial replacement of Portland cement on the development of compressive and flexural strength was evaluated until the age of, respectively, 365 and 208 days. The percentage of cement replacement, in weight, ranged from 20 to 50%, whereas the water/cement ratio ranged from 0.37 to 0.45. The results obtained show that the metakaolin and crushed calcined clay brick presented a good pozolanic activity and that the compressive strength of the blended mortars after 28 days of cure was higher than that observed for the reference Portland cement for all levels of cement replacement and water/cement ratio.

Calcium chloride was dissolved in sterile distilled water and blended with White Portland cement using a water to cement ratio of 0.5. Analysis of the bioactivity and pH of white Portland cement pastes with calcium chloride added at various amounts was carried out in simulated body fluid. Setting time, density, compressive strength and volume of permeable voids were also investigated. The characteristics of cement pastes were examined by X-ray diffractometer and scanning electron microscope linked to an energy-dispersive X-ray analyzer. The result indicated that the addition of calcium chloride could accelerate the hydration of white Portland cement, resulting in a decrease in setting time and an increase in early strength of the pastes. The compressive strength of all cement pastes with added calcium chloride was higher than that of the pure cement paste, and the addition of calcium chloride at 8 wt.% led to achieving the highest strength. Furthermore, white Portland cement pastes both with and without calcium chloride showed well-established bioactivity with respect to the formation of a hydroxyapatite layer on the material within 7 days following immersion in simulated body fluid; white Portland cement paste with added 3%CaCl 2 exhibited the best bioactivity. - Highlights: ► Optimization CaCl 2 content on the bioactivity and mechanical properties. ► CaCl 2 was used as an addition at 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10% by weight. ► CaCl 2 resulted in a decrease in setting time and an increase in early strength. ► Addition of 3%CaCl 2 exhibited the optimum formation of hydroxyapatite.

Binding of chloride and alkalis in Portland cement systems

Nielsen, Erik P.; Herfort, Duncan; Geiker, Mette R.

2005-01-01

A thermodynamic model for describing the binding of chloride and alkalis in hydrated Portland cement pastes has been developed. The model is based on the phase rule, which for cement pastes in aggressive marine environment predicts multivariant conditions, even at constant temperature and pressure. The effect of the chloride and alkalis has been quantified by experiments on cement pastes prepared from white Portland cements containing 4% and 12% C 3 A, and a grey Portland cement containing 7% C 3 A. One weight percent calcite was added to all cements. The pastes prepared at w/s ratio of 0.70 were stored in solutions of different Cl (CaCl 2 ) and Na (NaOH) concentrations. When equilibrium was reached, the mineralogy of the pastes was investigated by EDS analysis on the SEM. A well-defined distribution of chloride was found between the pore solution, the C-S-H phase, and an AFm solid solution phase consisting of Friedel's salt and monocarbonate. Partition coefficients varied as a function of iron and alkali contents. The lower content of alkalis in WPC results in higher chloride contents in the C-S-H phase. High alkali contents result in higher chloride concentrations in the pore solution

To study the effect of addition of various proportions of bismuth oxide on compressive strength and radiopacity of Portland cement. The compressive strength of white Portland cement and cement replaced with 10, 15, 20, 25 and 30% bismuth oxide was evaluated by testing cylinders 6 mm in diameter and 12 mm high. Twelve cylinders were tested for each material under study. The radiopacity of the cements tested was evaluated using an aluminium step-wedge and densitometer. The optical density was compared with the relevant thickness of aluminium (Al). Statistical analysis was performed using Analysis of Variance (ANOVA) with P = 0.05 and Tukey test to perform multiple comparison tests. Various additions of bismuth oxide had no significant effect on the strength of the material when compared with the unmodified Portland cement (P > 0.05). The radiopacity of the cements tested ranged from 2.02 mm Al for Portland cement to 9.79 mm Al for the highest bismuth replacement. Addition of bismuth oxide did not affect the compressive strength of Portland cement. All the bismuth oxide cement mixtures had radio-opacities higher than 3 mm thickness of aluminium.

2009-12-01

The purpose of this study was to compare the sealing ability of gray mineral trioxide aggregate (GMTA), white MTA (WMTA), and both white and gray Portland cement as furcation perforation repair materials. A total of 120 human mandibular first molars were used. After root canal obturation and preparation of furcal perforations the specimens were randomly divided into four groups of 25 teeth each. In groups A, B, C, and D furcation perforations were filled with WMTA, GMTA, white Portland cement, and type II Portland cement, respectively. Ten teeth were used as positive controls with no filling materials in the perforations and 10 teeth with complete coverage with two layers of nail varnish were used as negative controls. A protein leakage model utilizing 22% bovine serum albumin (BSA) was used for evaluation. Leakage was noted when color conversion of the protein reagent was observed. The controls behaved as expected. Leakage was found in the samples from group A (WMTA), group B (GMTA), and in the two other groups (white and gray Portland cement). There were no statistically significant differences between GMTA and WMTA or white and gray Portland cement, but significant differences were observed between the MTA groups and the Portland cement groups. It was concluded that Portland cements have better sealing ability than MTA, and can be recommended for repair of furcation perforation if the present results are supported by other in vivo and in vitro studies.

To assess automated external defibrillator (AED) distribution and cardiac emergency preparedness in Michigan secondary schools and investigate for association with school sociodemographic characteristics. Surveys were sent via electronic mail to representatives from all public high schools in 30 randomly selected Michigan counties, stratified by population. Association of AED-related factors with school sociodemographic characteristics were evaluated using Wilcoxon rank sum test and χ(2) test, as appropriate. Of 188 schools, 133 (71%) responded to the survey and all had AEDs. Larger student population was associated with fewer AEDs per 100 students (P schools. Schools with >20% students from racial minority groups had significantly fewer AEDs available per 100 students than schools with less racial diversity (P = .03). Schools with more students eligible for free and reduced lunch were less likely to have a cardiac emergency response plan (P = .02) and demonstrated less frequent AED maintenance (P = .03). Although AEDs are available at public high schools across Michigan, the number of AEDs per student varies inversely with minority student population and school size. Unequal distribution of AEDs and lack of cardiac emergency preparedness may contribute to outcomes of sudden cardiac arrest among youth. Copyright © 2016 Elsevier Inc. All rights reserved.

Mineral trioxide aggregate (MTA) and Portland cement have been shown to be bioactive because of their ability to produce biologically compatible carbonated apatite. This study analyzed the interaction of MTA and white Portland cement with dentin in vivo. Seventy-two human dentin tubes were filled with MTA Branco, MTA BIO, and white Portland cement + 20% bismuth oxide (PC1) or PC1 + 10% of calcium chloride (PC2) and implanted subcutaneously in 18 rats at 4 sites from the dorsal area. Empty dentin tubes, implanted in rats of a pilot study, were used as control. After 30, 60, and 90 days, the animals were killed, and the dentin tubes were retrieved for scanning electron microscope analysis. In the periods of 30 and 60 days, the mineral deposition in the material-dentin interface (interfacial layer) and in the interior of dentinal tubules was detected in more tubes filled with MTA Branco and MTA BIO than in tubes filled with PC1 and PC2. After 90 days, the interfacial layer and intratubular mineralization were detected in all tubes except for 3 and 1 of the tubes filled with PC2, respectively. It was concluded that all the cements tested were bioactive. The cements released some of their components in the tissue capable of stimulating mineral deposition in the cement-dentin interface and in the interior of the dentinal tubules. MTA BIO and MTA Branco were more effective in promoting the biomineralization process than Portland cements, mainly after 30 and 60 days. Copyright © 2012 American Association of Endodontists.

2014-09-01

This study examined the availability of free drinking water during lunchtime in US public schools, as required by federal legislation beginning in the 2011-2012 school year. Data were collected by mail-back surveys in nationally representative samples of US public elementary, middle, and high schools from 2009-2010 to 2011-2012. Overall, 86.4%, 87.4%, and 89.4% of students attended elementary, middle, and high schools, respectively, that met the drinking water requirement. Most students attended schools with existing cafeteria drinking fountains and about one fourth attended schools with water dispensers. In middle and high schools, respondents were asked to indicate whether drinking fountains were clean, and whether they were aware of any water-quality problems at the school. The vast majority of middle and high school students (92.6% and 90.4%, respectively) attended schools where the respondent perceived drinking fountains to be clean or very clean. Approximately one in four middle and high school students attended a school where the survey respondent indicated that there were water-quality issues affecting drinking fountains. Although most schools have implemented the requirement to provide free drinking water at lunchtime, additional work is needed to promote implementation at all schools. School nutrition staff at the district and school levels can play an important role in ensuring that schools implement the drinking water requirement, as well as promote education and behavior-change strategies to increase student consumption of water at school.

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.

The aim of this in vitro study was to determine the liquid-powder ratio, setting time, solubility, dimensional change, pH, and radiopacity of white structural and non-structural Portland cement, ProRoot MTA and MTA Bio, associated with a 2% glycolic solution containing Aloe Vera, as vehicle. Five samples of each material were used for each test, according to the American National Standards Institute/American Dental Association (ANSI/ADA) specification No. 57. Statistical analyses were performed using ANOVA and Tukey's test at 5% significance. When sample distribution was not normal, non-parametric analysis of variance and the Kruskal-Wallis test were used ( α =0.05). No statistical differences were found in liquid-powder ratios among the tested materials. ProRoot MTA showed the longest setting time. Dimensional change values were acceptable in all groups. Also, no significant differences were found in pH values and pH was alkaline in all samples throughout the experiment. Mean radiopacity results obtained for white Portland cements did not meet ANSI/ADA requirements, and were significantly lower than those obtained for MTA-based cements. Finally, Portland cements showed significantly higher mean solubility values compared to the other samples. The physicochemical properties of the tested materials in association with Aloe Vera were compatible with ANSI/ADA requirements, except for the white Portland cements, which failed to meet the radiopacity specification.

Camilleri, J; Cutajar, A; Mallia, B

2011-08-01

Zirconium oxide can be added to dental materials rendering them sufficiently radiopaque. It can thus be used to replace the bismuth oxide in mineral trioxide aggregate (MTA). Replacement of Portland cement with 30% zirconium oxide mixed at a water/cement ratio of 0.3 resulted in a material with adequate physical properties. This study aimed at investigating the microstructure, pH and leaching in physiological solution of Portland cement replaced zirconium oxide at either water-powder or water-cement ratios of 0.3 for use as a root-end filling material. The hydration characteristics of the materials which exhibited optimal behavior were evaluated. Portland cement replaced by zirconium oxide in varying amounts ranging from 0 to 50% in increments of 10 was prepared and divided into two sets. One set was prepared at a constant water/cement ratio while the other set at a constant water/powder ratio of 0.3. Portland cement and MTA were used as controls. The materials were analyzed under the scanning electron microscope (SEM) and the hydration products were determined. X-ray energy dispersive analysis (EDX) was used to analyze the elemental composition of the hydration products. The pH and the amount of leachate in Hank's balanced salt solution (HBSS) were evaluated. A material that had optimal properties that satisfied set criteria and could replace MTA was selected. The microstructure of the prototype material and Portland cement used as a control was assessed after 30 days using SEM and atomic ratio diagrams of Al/Ca versus Si/Ca and S/Ca versus Al/Ca were plotted. The hydration products of Portland cement replaced with 30% zirconium oxide mixed at water/cement ratio of 0.3 were calcium silicate hydrate, calcium hydroxide and minimal amounts of ettringite and monosulphate. The calcium hydroxide leached in HBSS solution resulted in an increase in the pH value. The zirconium oxide acted as inert filler and exhibited no reaction with the hydration by-products of Portland

Tribal vs. Public Schools: Perceived Discrimination and School Adjustment among Indigenous Children from Early to Mid-Adolescence.

Science.gov (United States)

Crawford, Devan M; Cheadle, Jacob E; Whitbeck, Les B

2010-04-01

The purpose of this study is to assess the differential effects of perceived discrimination by type of school on positive school adjustment among Indigenous children during late elementary and early middle school years. The analysis utilizes a sample of 654 Indigenous children from four reservations in the Northern Midwest and four Canadian First Nation reserves. Multiple group linear growth modeling within a structural equation framework is employed to investigate the moderating effects of school type on the relationship between discrimination and positive school adjustment. Results show that students in all school types score relatively high on positive school adjustment at time one (ages 10-12). However, in contrast to students in tribal schools for whom positive school adjustment remains stable, those attending public schools and those moving between school types show a decline in school adjustment over time. Furthermore, the negative effects of discrimination on positive school adjustment are greater for those attending public schools and those moving between schools. Possible reasons for this finding and potential explanations for why tribal schools may provide protection from the negative effects of discrimination are discussed.

An amount of 5 mL of hydrochloric acid was added to 2 g each of MTA and Portland cement to be analyzed. After 15 minutes, the material was filtered and the volume of supernatant was diluted with reagent-grade water up to 40 mL. Atomic absorption spectrophotometry readings were performed in triplicate. The following mean values were obtained: CPM (Egeo, Buenos Aires, Argentina) 11.06 mg/kg; CPM sealer (Egeo) 10.30 mg/kg; MTA-Obtura (Angelus, Londrina, PR, Brazil) 0.39 mg/kg; Experimental MTA: 10.30 mg/kg; White MTA-Angelus (Angelus) 1.03 mg/kg; Gray MTA-Angelus (Angelus) 5.91 mg/kg; ProRoot-MTA (Dentsply/Tulsa Dental Specialties, Tulsa, OK) 5.25 mg/kg; Gray Portland cement (Votorantim Cimentos, Cubatão, SP, Brazil): 34.27 mg/kg; and White Portland cement (Cimento Rio Branco, Rio de Janeiro, RJ, Brazil) 0.52 mg/kg. All tested materials presented arsenic in their composition. The form of arsenic was not analyzed nor the toxicity of the arsenic found. Only MTA-Obtura, White MTA-Angelus, and White Portland cement presented arsenic levels below the limit set in the ISO 9917-1 standard.

Overburndened and Underfunded: California Public Schools Amidst the Great Recession

Full Text Available Since 2008, many nations, including the United States, have struggled with the effects of a global recession. The state of California has been particularly impacted by the Great Recession. Unemployment rates in California are among the highest in the United States, and a weak fiscal environment has forced deep cutbacks to a variety of state services. This study uses California as a case to explore the effects of economic crisis on public schools and the students they serve. The study draws on two years of survey and interview data with a representative sample of public school principals across California. The data show that, during the Great Recession, students have experienced growing social welfare needs that often shape their well-being and their performance in schools. We also find that the capacity of public schools to meet these needs and provide quality education has been eroded by budget cuts. This study finds that schools primarily serving low-income families have been hardest hit during the recession, in part because they cannot raise private dollars to fill the gap left by public sector cuts. The Great Recession thus has undermined educational quality while producing widening educational inequality in California.

Effect of three natural pozzolans in portland cement hydration

Full Text Available Natural pozzolans have been used since ancient times and continues to be used today. The chemistry and morphological composition of natural pozzolans and their particle size distribution allows classifying them as more or less reactive pozzolan. In this research several techniques have been used to study the influence of pozzolan on portland cement hydration as much as to evaluate the mechanical and durable properties of concretes, mortars and pastes containing pozzolans. This paper describes the effect of incorporating three natural pozzolans to two cements with very different mineralogical composition. The techniques used were: conduction calorimetry and Fratini test. Results proved that pozzolanic activity and the acceleration and retardation of hydration reaction depend on the mineralogical composition of the portland cernent used. Effects of dilution, stimulation, acceleration or retardation reactions, behavior into areas of heat dissipation and pozzolanic activity depend on the percentage of pozzolan used and the age in which it has been analyzed.

El uso de las puzolanas naturales se remonta a la antigüedad, no obstante, actualmente continúa su utilización. La composición química y morfológica de las puzolanas naturales, sumado al tamaño de sus partículas, las califican como más o menos reactivas. En el estudio de las mismas, se han aplicado variadas técnicas para el análisis de sus interferencias en las reacciones de hidratación de los cementos portland; así como para la evaluación de las propiedades resistentes y duraderas que pueden conferirle a los hormigones, morteros o pastas de los que formen parte. Este trabajo versará sobre los efectos que produce la incorporación de tres puzolanas naturales a dos cementos portland de muy diferente composición mineralógica. Las técnicas aplicadas para su estudio han sido: la calorimetría de conducción y el ensayo de Fratini. Los resultados obtenidos permiten determinar

Full Text Available ABSTRACT The current focus on change management practices in the Public sector has been significantly induced by new public management paradigm shift that places heavy emphasis on managing for results. This is an emerging issue particularly in public secondary schools. The purpose of this study was to relate public secondary schools with the practice of generally established change management best practices. The specific objectives of the study were to establish change management practices adopted by Public Secondary Schools in Siaya Sub County. The study population consisted of all the 38 Public Secondary Schools in Siaya Sub County which necessitated the adoption of a descriptive cross-sectional survey design and the school managers were to respond to questionnaire items designed to address aspects of best change management practices. The researcher wanted to find out the extent to which the schools practiced these virtues. The school managers stated that they moderately practiced aspects of planning committed leadership workforce alignment stakeholder involvement and had defined governance structures in their institutions. However the extents were varying from one school to the next. Multiple regressions were run using the change management practices dimensions established against performance dimensions of student enrolment participation in co-curricular activities KCSE achievement financial management and provision of teaching and learning resources and development of school infrastructure. The study found out that change management practices adopted by the institutions significantly influenced performance. The study recommends that there is need to break from status quo and bureaucratic inefficiency associated with public institutions and be ready to implement comprehensive change management practices to maximize on resource utilization our public educational institutions. The study would contribute towards broadening the knowledge base of

Given the increase in childhood food allergy, national and local policies have been developed to encourage schools to stock undesignated epinephrine auto-injectors in case of an anaphylactic emergency. To describe the use of epinephrine auto-injectors in Chicago Public Schools during the 2012-2013 school year, specifically for food-induced allergic reactions. District-issued epinephrine auto-injectors were distributed to all public and charter schools in Chicago prior to the start of the 2012-2013 school year. Data on their use were collected, and frequencies were computed in the autumn of 2013. Thirty-eight district-issued epinephrine auto-injectors were administered during the inaugural year of the Chicago Public Schools initiative. Epinephrine auto-injectors were administered to students (92.1%) and school staff (7.9%). Most district-issued epinephrine auto-injectors were administered in elementary schools (63.2%) and on Chicago's North-Northwest Side (36.8%). More than half (55.0%) of all district-issued epinephrine auto-injectors were administered for first-time anaphylactic events. Food-induced reactions accounted for more than half (55.3%) of all reactions requiring epinephrine auto-injector use, whereas the trigger of more than one third (34.2%) of all reactions requiring the use of an epinephrine auto-injector remained unknown. Chicago Public Schools is the first large, urban school district in the U.S. to develop and implement the District-Issued Emergency Epinephrine Initiative, which helped 38 students and staff avoid potential morbidity and mortality. The impact of this initiative during its first year underscores the need for stocking undesignated epinephrine in schools across the country. Copyright © 2015 American Journal of Preventive Medicine.

Internal grade inflation is a documented practice in secondary schools (mostly in private schools) that jeopardises fairness with regard to access to medical school. However, it is frequently assumed that the higher internal grades are in fact justifiable, as they correspond to better preparation of students in private schools in areas that national exams do not cover but nevertheless are important. Consequently, it is expected that students from private schools will succeed better in medical school than their colleagues, or at least not perform worse. We aimed to study whether students from private schools do fare better in medical school than their colleagues from public schools, even after adjusting for internal grade inflation. We analysed all students that entered into a medical course from 2007 to 2014. A linear regression was performed using mean grades for the 1st-year curse units (CU) of the medical school curriculum as a dependent variable and student gender, the nature of students' secondary school (public/private), and whether their secondary school highly inflated grades as independent variables. A logistic regression was also performed, modelling whether or not students failed at least one CU exam during the 1st year of medical school as a function of the aforementioned independent variables. Of the 1709 students analysed, 55% came from public secondary schools. Private (vs. public) secondary school (β = - 0.459, p schools highly inflated grades (β = - 0.246, p = 0.003) were independent factors that significantly influenced grades during the first year of medical school. Having attended a private secondary school also significantly increased the odds of a student having failed at least one CU exam during the 1st year of medical school (OR = 1.33), even after adjusting for whether or not the secondary school used highly inflated grades. It is important to further discuss what we can learn from the fact that students from public

The objective of this research was to evaluate the response of Portland cement associated with different radio pacifying agents on pulp treatment of human primary teeth by clinical and radiographic exams and microscopic analysis. Thirty mandibular primary molars were randomly divided into the following groups: Group I - Portland cement; Group II - Portland cement with iodoform (Portland cement + CHI3 ); Group III - Portland cement with zirconium oxide (Portland cement + ZrO2 ); and treated by pulpotomy technique (removal of a portion of the pulp aiming to maintain the vitally of the remaining radicular pulp tissue using a therapeutic dressing). Clinical and radiographic evaluations were recorded at 6, 12 and 24 months follow-up. The teeth at the regular exfoliation period were extracted and processed for histological analysis. Data were tested using statistical analysis with a significance level of 5%. The microscopic findings were descriptively analysed. All treated teeth were clinically and radiographically successful at follow-up appointments. The microscopic analysis revealed positive response to pulp repair with hard tissue barrier formation and pulp calcification in the remaining roots of all available teeth. The findings of this study suggest that primary teeth pulp tissue exhibited satisfactory biological response to Portland cement associated with radio pacifying agents. However, further studies with long-term follow-up are needed to determine the safe clinical indication of this alternative material for pulp therapy of primary teeth. © 2015 The Authors Journal of Microscopy © 2015 Royal Microscopical Society.

Silva, A.R. da; Cabral, K.C.; Pinto, E.N. de M.G.l.

2016-01-01

The objective of this study is to analyze the pozzolanic activity of red ceramic residue on the partial replacement of Portland cement in mortars. The mortars were prepared by substituting 25% of the Portland cement for ground of ceramic residue with water cement’s factor of 0.48. The concrete used to construct the reference mortars and those with addiction was CPII-Z-32 (compound of Portland pozzolana cement). The chemical analysis and physical ceramic waste showed that this meets the requirements of NBR12653 (2014) for use as pozzolanic material. The pozzolanic activity index (IAP) obtained for the ceramic waste to twenty-eight days cure rate was 80.28%. (author)

[Hygiene in schools - an important issue for the public health services].

Heudorf, U; Voigt, K; Eikmann, Th; Exner, M

2011-11-01

According to the Protection against Infection Act (IfSG), schools have to identify their arrangements of standard operating procedures (SOPs) for hygienic conditions, and the public health departments are obliged to check the hygienic conditions in schools. Here, practical experience with these topics in Frankfurt/Main, Germany, is presented.Although all schools had been informed about their duties according to IfSG in 2001, only 44% (80/180 schools) of them were able to present their SOPs when requested to do so by the public health department in 2006. Complaints about bad sanitary hygiene in schools have to be confirmed, often even in recently redeveloped facilities, because of vandalism. The equipment of washing basins was improved very well during the influenza pandemic in 2009. In 2010, however, a tendency to deterioration had been observed. With data on high levels on indoor contamination (particles and CO2) in class rooms in 2006, the city increased the frequency of cleaning and launched a programme on proper ventilation in classrooms. However, a study on ventilation in 29 schools in 2009 resulted in very high levels of CO2; obviously the recommendation to ventilate the classrooms every break are neglected. Large studies on drinking water quality exhibited good data, with the exception of high Legionella contaminations in hot water systems supplying the showers in gymnasiums. Major redevelopment measures were necessary.Hygienic conditions in schools should be improved urgently. The public health departments should increase their consulting services as well as their control visits in schools - with the aim to improve hygiene in schools. Responsibility of the schools as well as of the individuals in the schools is demanded as well. More public attention to this topic seems mandatory, may be via a "signal light - red-yellow-green" for schools? © Georg Thieme Verlag KG Stuttgart · New York.

Thompson, Dennis F; Nahata, Milap C

2012-11-12

To determine yearly (phase 1) and cumulative (phase 2) publication records of pharmaceutical science faculty members at research-intensive colleges and schools of pharmacy. The publication records of pharmaceutical science faculty members at research-intensive colleges and schools of pharmacy were searched on Web of Science. Fifty colleges and schools of pharmacy were randomly chosen for a search of 1,042 individual faculty members' publications per year from 2005 to 2009. A stratified random sample of 120 faculty members also was chosen, and cumulative publication counts were recorded and bibliometric indices calculated. The median number of publications per year was 2 (range, 0-34). Overall, 22% of faculty members had no publications in any given year, but the number was highly variable depending on the faculty members' colleges or schools of pharmacy. Bibliometric indices were higher for medicinal chemistry and pharmaceutics, with pharmacology ranking third and social and administrative sciences fourth. Higher bibliometric indices were also observed for institution status (ie, public vs private) and academic rank (discipline chairperson vs non-chairperson and professor vs junior faculty member) (ppharmaceutical science disciplines and academic ranks within research-intensive colleges and schools of pharmacy. These data may be important for benchmarking purposes.

Clinical, radiological and histological evaluation of root perforations treated with mineral trioxide aggregate (MTA) or Portland cements, and calcium sulfate barrier. One molar and 11 premolar teeth of a male mongrel dog received endodontic treatment and furcations were perforated with a high-speed round bur and treated with a calcium sulfate barrier. MTA, Portland cement type II (PCII) and type V (PCV), and white Portland cement (WPC) were used as obturation materials. The teeth were restored with composite resin and periapical radiographs were taken. The animal was euthanized 120 days post-surgery for treatment evaluation. Right lower first premolar (MTA), right lower third premolar (PCV), left lower second premolar (MTA), and right lower second premolar (WPC): clinically normal, slightly radio-transparent area on the furcation, little inflammatory infiltrate, and new-bone formation. Left lower third premolar (PCII), right upper first premolar (WPC), right upper third premolar (PCII), and left upper first molar (PCV): clinically normal, radiopaque area on the furcation, and new-bone formation. Right upper second premolar (MTA), left upper second premolar (WPC), left upper third premolar (PCII): presence of furcation lesion, large radiolucent area, and intense inflammatory infiltrate. All obturation materials used in this study induced new-bone formation.

Public Accountability: The Perceived Usefulness of School Annual Reports

2010-06-01

Full Text Available Annual reports are an important component of New Zealand schools’ public accountability. Through theannual report the governance body informs stakeholders about school aims, objectives, achievements, use ofresources, and financial performance. This paper identifies the perceived usefulness of the school annualreport to recipients and the extent to which it serves as an instrument of accountability and/or decisionusefulness.The study finds that the annual report is used for a variety of purposes, including: to determine ifthe school has conducted its activities effectively and achieved stated objectives and goals; to examine studentachievements; to assess financial accountability and performance; and to make decisions about the school as asuitable environment for their child/children. Nevertheless, the study also finds that other forms ofcommunication are more important sources of information about the school than the annual report which isseen to fall short of users’ required qualities of understandability, reliability and readability. It would appearimperative that policy makers review the functional role of the school annual report which is a costlydocument to prepare. Further, school managers need to engage in alternative means to communicatesufficient and meaningful information in the discharge of public accountability.

Full Text Available The purpose of this study was to examine the relationship between the size of Alabama’s public high schools, selected school quality and financial indicators, and their students’ performance on standardized exams. When the socioeconomic level of the student bodies is held constant, the size of high schools in Alabama has relatively little relationship with 11th grade student (both regular and special education performance on the reading and math portions of the Alabama High School Graduation Exam (AHSGE. High schools’ average daily attendance rates and pupil-to-computer (and computer with Internet connections ratios do not vary in accordance with school size. Higher percentages of highly qualified teachers are found in Alabama’s largest high schools. There was very little difference in the percentage of teachers with a master’s degree or above across school size categories. Very little difference exists across size categories in regard to mean expenditures per pupil (range = $7,322 to $7,829. However, districts of the large high schools exert over twice the effort of those with small high schools (3.2 mills to 1.5 mills and approximately 50 percent greater local effort than the districts of the medium-size high schools.

To compare the spelling ability of schoolchildren from the fourth to sixth grades of the elementary schools in the private and public schools of Bauru, São Paulo, and to verify whether errors are overcome as studies progress and the hierarchy of errors as to how often they occur. A dictation was applied to 384 schoolchildren: 206 from the private schools: 74 were at the fourth grade, 65 at the fifth grade, and 67 at the sixth grade; and 178 from the public schools; 56 at the fourth grade, 63 at the fifth grade, and 59 at the sixth grade of elementary school. Student's t test was used. In comparison of total spelling errors score, difference was found among the fourth and sixth grades of the private and public schools. Spelling errors decreased as education progressed, and those related to language irregularities were more common. Spelling ability and performance of students from the private and public schools are not similar in the fourth and sixth grades, but it is in the fifth grade. Spelling errors are gradually overcome as education progresses; however, this overcome rate was considerable between the fourth and fifth grades in the public schools. Decrease in the types of spelling errors follows a hierarchy of categories: phoneme/grapheme conversion, simple contextual rules, complex contextual rules, and language irregularities. Finally, the most common type of spelling error found was that related to language irregularities.

2013-06-01

Accreditation criteria by the Council on Education for Public Health (CEPH) state that prior to graduation, Masters of Public Health (MPH) students must demonstrate the application of knowledge and skills through a practice experience, commonly called the "Practicum." The purpose of this research was to review those MPH Practicum requirements. Practicum guidelines from US-based schools of public health that were accredited as of October 2011 were reviewed. Data on each Practicum's level of coordination, timing, and credit and contact hours as well as information about written agreements, preceptors, and how the Practicum was graded were collected. Seventy-four Practicums in 46 accredited schools of public health were reviewed. The majority (85 %) of accredited schools controlled the Practicum at the school-level. Among the Practicums reviewed, most did not require completion of any credit hours or the MPH core courses (57 and 74 %, respectively) prior to starting the Practicum; 82 % required written agreements; 60 % had stated criteria for the approval of preceptors; and 76 % required students to submit a product for grading at the conclusion of the Practicum. The results of this research demonstrate that the majority of accredited schools of public health designed Practicum requirements that reflect some of the criteria established by CEPH; however, issues related to timing, credit and contact hours, and preceptor qualifications vary considerably. We propose that a national dialogue begin among public health faculty and administrators to address these and other findings to standardize the Practicum experience for MPH students.

2013-01-01

One issue that has pervaded policy discussions for decades is the difficulty that school districts experience in retaining teachers. Almost a quarter of entering public school teachers leave teaching within the first three years and empirical evidence has related high attrition rates of beginner teachers to family circumstances, such as maternity or marriage. I examine female teachers' career choices and inquire about the effects that wage increases and child care subsidies have on their empl...

Structure investigations on Portland cement paste by small angle neutron scattering

International Nuclear Information System (INIS)

Dragolici, C.A.; Lin, A.

2004-01-01

Hydrated Portland cement is a very complex material. Cement paste consists of many crystalline and non-crystalline phases in various ranges of sizes (μm and nm scale). The crystalline phases are embedded in amorphous phases of hydration products. We investigated the structural changes of hydrating phases in a time interval up to 18 days, at Budapest Neutron Center's SANS spectrometer. The small angle neutron scattering of Portland cements prepared with a various water-to-cement ratios, gave us information about the microstructure changes in the material. Fractals were a suitable way for structure modelling. Some comments regarding the opportunity of using the most common models are pointed out. (authors)

Karanth, P; Manjunath, M K; Kuriakose, E S

2013-01-01

This secondary-level animal study was conducted to assess and compare the subcutaneous tissue reaction to implantation of white mineral trioxide aggregate (MTA) and white Portland cement. Polyethylene tubes filled with either freshly mixed white MTA (Group I) or white Portland cement (Group II) were implanted subcutaneously into 12 Wistar Albino rats. Each animal also received an empty polyethylene tube as the control (Group III). After 7, 14, 21 and 30 days, the implants, together with surrounding tissues were excised. Two pathologists blinded to the experimental procedure, evaluated sections taken from the biopsy specimens for the severity of the inflammatory response, calcification and the presence and thickness of fibrous capsule surrounding the implant. Statistical analysis was performed using the Cross-tabs procedure, Univariate analysis of the variance two-way and the Pearson product moment correlation to assess inter-rater variability between the two evaluators. At 7 days, there was no significant difference in the severity of inflammation between the control group, white MTA, and white Portland cement groups. In the 14 day, 21 day and 30 day test periods, control group had significantly less inflammation than white MTA and white Portland cement. There was no significant difference in the grading of inflammation between white MTA and white Portland cement. All materials exhibited thick capsule at 7 days and thin capsule by 30 days. Both white MTA and white Portland cement were not completely non-irritating at the end of 30 days as evidenced by the presence of mild inflammation. However, the presence of a thin capsule around the materials, similar to the control group, indicates good tissue tolerance. White MTA and white Portland cement seem to be materials of comparable biocompatibility.

The present study examined differences in dietary habits and physical activity levels between students attending private and public high schools in Jordan. A total of 386 secondary-school males and 349 females aged 14-18 years were randomly recruited using a multistage, stratified, cluster sampling technique. Dietary habits and physical activity level were self-reported in a validated questionnaire. The prevalence of obesity was significantly higher among adolescents in private (26.0%) than in public schools (16.7%). The frequency of breakfast intake was significantly higher among adolescents in private schools, whereas French fries and sweets intake was significantly higher in public schools. Television viewing showed a significant interaction with school type by sex. A higher rate of inactivity was found among students attending private schools. Despite a slightly better overall dietary profile for students in private schools, they had a higher rate of overweight and obesity compared with those in public schools.

Neuropsychological assessment reveals that certain cognitive changes that take place during the neural development process may be associated with biopsychosocial issues. A substantial body of research has focused on cognitive development in children and adults, but few such studies have been carried out on adolescents. Therefore, research into the processing of neuropsychological functions in adolescents, taking into account the role of major socio-cultural factors such as school type (public vs. private), is highly relevant. The present study sought to assess whether differences in neuropsychological development exist between adolescent students of public (government-funded) and private schools. A total of 373 grade-matched students between the ages of 12 and 18, 190 from public schools and 183 from private schools, took part in the study. All subjects had no self-reported neurologic or psychiatric conditions and sensory disorders. The NEUPSILIN Brazilian Brief Neuropsychological Assessment Battery was administered to this sample. Comparison of mean scores (one-way ANCOVA with socioeconomic score and age as covariates) showed that adolescents attending private schools generally outperformed their public-school peers in tasks involving sustained attention, memory (working and visual), dictated writing, and constructional and reflective abilities. We conclude that school type should be taken into account during standardization of neuropsychological assessment instruments for adolescent and, probably, child populations.

Justice, Laura M; Jiang, Hui; Logan, Jessica A; Schmitt, Mary Beth

2017-06-10

This study aimed to identify child-level characteristics that predict gains in language skills for children with language impairment who were receiving therapy within the public schools. The therapy provided represented business-as-usual speech/language treatment provided by speech-language pathologists in the public schools. The sample included 272 kindergartners and first-graders with language impairment who participated in a larger study titled "Speech-Therapy Experiences in the Public Schools." Multilevel regression analyses were applied to examine the extent to which select child-level characteristics, including age, nonverbal cognition, memory, phonological awareness, vocabulary, behavior problems, and self-regulation, predicted children's language gains over an academic year. Pratt indices were computed to establish the relative importance of the predictors of interest. Phonological awareness and vocabulary skill related to greater gains in language skills, and together they accounted for nearly 70% of the explained variance, or 10% of total variance at child level. Externalizing behavior, nonverbal cognition, and age were also potentially important predictors of language gains. This study significantly advances our understanding of the characteristics of children that may contribute to their language gains while receiving therapy in the public schools. Researchers can explore how these characteristics may serve to moderate treatment outcomes, whereas clinicians can assess how these characteristics may factor into understanding treatment responses.

We compared the prevalence of body weight categories between public and private schools in the Seychelles, a rapidly developing small island state in the African region. In 2004-2006, weight and height were measured and self-reported information on physical activity collected in children of three selected grades in all schools in the country. Overweight, obesity and thinness were defined according to standard criteria. Based on 8 462 students (377 in private schools), the prevalence of overweight (including obesity) was markedly higher in private than public schools (boys: 37% [95% CI: 31-44] vs. 15% [14-16]; girls: 33% [26-41] vs. 20% [19-22]). The prevalence of thinness grade 1 was lower in private than public schools (boys: 9% [5-13] vs. 20% [19-21]; girls: 13% [8-18] vs. 19% [18-20]). Students in private schools reported more physical activity at leisure time while students in public schools reported larger weekly walking time. Our findings suggest that school type may be a useful indicator for assessing the association between socio-economic status and overweight in children, and that overweight affects wealthy children more often than others in developing countries.

The prevalence of hypertension in childhood is increasing, and investigation of its distribution is important for planning timely interventions. This study assessed the prevalence of high blood pressure (HBP) and associated factors in students between 9 and 11 years of age enrolled in public and private schools in Maceió, Brazil. A cross-sectional study was performed in a probabilistic sample of students (10.3 ± 0.5 years). The students were selected from a systematic sampling of 80 schools (40 public and 40 private). To maintain similar proportions of students existing in public and private schools in Maceió, 21 and 14 students were randomly selected from each public and private school, respectively. The prevalence ratio (PR) was estimated using Poisson regression. A total of 1,338 students were evaluated (800 from public schools and 538 from private schools). No differences were observed between school types in terms of student age and gender (p > 0.05). The prevalence of obesity (19.9% vs. 9.0%; PR = 2.2; 95% CI = 1.67-2.92) and hypertension (21.2% vs. 11.4%; PR = 1.86; 95% CI = 1.45-2.40) were higher in private schools. The association between high blood pressure and type of school (public or private) remained statistically significant even after adjustment for obesity (PR = 1.53; 95% CI = 1.19-1.97). (a) students from private schools have higher socioeconomic status, BMI, and HBP prevalence compared to those of public school; (b) among the evaluated students, the prevalence of obesity only partially explained the higher prevalence of high blood pressure among students from private schools. Other factors related to lifestyle of children from private schools may explain the higher prevalence of HBP. This results show the need to implement measures to promote healthy lifestyles in the school environment, since children with HBP are more likely to become hypertensive adults. Therefore, early detection and intervention in children with HBP is an important action

Otok, Robert; Czabanowska, Katarzyna; Foldspang, Anders

2017-11-01

The establishment and continuing development of a sufficient and competent public health workforce is fundamental for the planning, implementation, evaluation, effect and ethical validity of public health strategies and policies and, thus, for the development of the population's health and the cost-effectiveness of health and public health systems and interventions. Professional public health strategy-making demands a background of a comprehensive multi-disciplinary curriculum including mutually, dynamically coherent competences - not least, competences in sociology and other behavioural sciences and their interaction with, for example, epidemiology, biostatistics, qualitative methods and health promotion and disease prevention. The size of schools and university departments of public health varies, and smaller entities may run into problems if seeking to meet the comprehensive curriculum challenge entirely by use of in-house resources. This commentary discusses the relevance and strength of establishing comprehensive curriculum development networks between schools and university departments of public health, as one means to meet the comprehensiveness challenge. This commentary attempts to consider a two-stage strategy to develop complete curricula at the bachelor and master's as well as PhD levels.

2017-08-01

The growth and unregulated structure of homeschooling creates an unknown population in regard to muscular and cardiorespiratory fitness. The purpose of this research was to compare muscular and cardiorespiratory fitness between elementary school aged homeschool and public school children. Homeschool children ages 8-11 years old (n = 75) completed the curl-up, 90° push-up, and Progressive Aerobic Capacity Endurance Run (PACER) portions of the FitnessGram to assess abdominal and upper body strength and endurance as well as cardiorespiratory fitness. Comparisons to public school children (n = 75) were made using t tests and chi-square tests. Homeschool children showed significantly lower abdominal (t(148) = -11.441, p fitness by total PACER laps (t(108) = 0.879, p = .381) or estimated VO 2max (t(70) = 1.187, p = .239; χ 2 (1) = 1.444, p = .486). Homeschool children showed significantly lower levels of both abdominal and upper body muscular fitness compared with their age and gender matched public school peers but no difference in cardiorespiratory fitness.

Watson, Anne H; Ito, Max; Smith, Roger O; Andersen, Lori T

2010-01-01

The Individuals With Disabilities Education Improvement Act of 2004 (IDEA) requires assistive technology (AT) be considered at the yearly individualized education program (IEP) meeting of every student in special education. IDEA also directs that AT be implemented on the basis of peer-reviewed literature despite a paucity of research on AT's effectiveness in the public schools. This repeated-measures quasi-experimental study explored AT's effect in a public school special education setting. Participants (N=13) were a heterogeneous group of students in 1 school system who had newly provided AT to address academic and communication goals in one school year. Results suggest that relative to other interventions, AT provided by a multidisciplinary team may have a significant effect on IEP goal improvement (t[12] = 5.54, p= .00) for students in special education (F[2] = 9.35, p= .00), which may support AT's use in special education by occupational therapists as directed by IDEA.

Gladwin, Catherine P; Church, John; Plotnikoff, Ronald C

2008-01-01

Public policies impact the amount of physical activity (PA) that children receive at school. These policies are of interest because overweight and obesity among Canadian children have grown at significant rates, and increasing PA among children is one way to reverse this trend. This research investigates the public policy processes that have resulted in Alberta's education system adopting in-school daily physical activity (DPA) and not supporting walk-to-school (WTS) initiatives. Using the policy process described by Kingdon and others as a conceptual framework, this research reviews literature and documents on public policy relating to PA in schools and interviews key individuals (N = 20) to identify the policy-related facilitators and barriers in Alberta, Canada to increasing PA in school-aged children. DPA was mandated because Kingdon's three policy streams (problem, solution and politics) became joined or linked. DPA was the most viable solution because literature supports and teachers believe in the educational benefits of PA. As well, a physician with personal beliefs about the benefits of PA became the minister of education and coupled the solution with the political stream through his ministerial power. Reasons that WTS programs have not become school or health policy include advocacy led by politically weak organizations, lack of a supportive policy entrepreneur and poor saliency among educators. This research illuminates the inner workings of the policy process shaping PA in schools, identifying the unseen forces of the policy process that move issues forward. The findings provide valuable insight for building other healthy public policies.

Dragolici, C. A.; Len, A.

2003-01-01

Portland cement pastes consist of many crystalline and non-crystalline phases in various ranges of sizes (nm and mm scale). The crystalline phases are embedded in amorphous phases of the hydration products. We investigated the structural changes of hydrating phases in the time interval of 1-30 days at Budapest Neutron Center's SANS diffractometer. The small angle neutron scattering of Portland cements prepared with a water-to-cement ratio from 0,3 to 0,8 gave us information about the microstructure changes in the material. Fractals were a suitable way for structure modelling. The variation of fractals size depending on the preparation-to-measurement time interval and water-to-cement ratio could be observed. (authors)

Full Text Available BACKGROUND: Few data are available evaluating the associations of formal public health education with long-term career choice and professional outcomes among medical school graduates. The objective of this study was to determine if formal public health education via completion of a masters of public health (MPH degree among US medical school graduates was associated with early and long-term career choice, professional satisfaction, or research productivity. METHODS: We conducted a retrospective cohort study in 1108 physicians (17.1% completed a MPH degree who had 10-20 years of follow-up post medical school graduation. Multivariable logistic regression analyses were conducted. RESULTS: Compared to their counterparts with no MPH, medical school graduates with a MPH were more likely to have completed a generalist primary care residency only [relative risk (RR 1.79, 95% confidence interval (CI 1.35-2.29], obtain employment in an academic institution (RR 1.81; 95% CI 1.33-2.37 or government agency (RR 3.26; 95% CI 1.89-5.38, and practice public health (RR 39.84; 95% CI 12.13-107.38 or primary care (RR 1.59; 95% CI 1.18-2.05. Furthermore, medical school graduates with a MPH were more likely to conduct public health research (RR 8.79; 95% CI: 5.20-13.82, receive NIH or other federal funding (RR 3.11, 95% CI 1.74-5.33, have four or more peer-reviewed publications (RR 2.07; 95% CI 1.56-2.60, and have five or more scientific presentations (RR 2.31, 95% CI 1.70-2.98. CONCLUSION: Formal public health education via a MPH was associated with career choice and professional outcomes among physicians.

Full Text Available Objective: To assess the perception of violence from the reports of teachers of elementary and high school in a public state school in Fortaleza, Ceará. Method: A qualitative descriptive study conducted with 26 teachers, in the period from January to May 2006. To collect the data we adopted the following procedures: the discussion on school violence during the meetings of the teacher training week; the reading of the school regulations and the distribution of an instrument with the guiding question about the concept of violence as from the school reality, among the participants of the study. Afterwards, the thematic analysis of the reports was carried out. Results: Through the reports of teachers emerged the following categories: physical aggression, verbal aggression and fights as the most cited; to hide personal belongings, cursing, shoving and disrespect for the teacher and pranks were also mentioned. Conclusion: From the reports it appears that violence is perceived in physical, dimension moral and symbolic, and these “typologies” corroborate the descriptions found in literature as bullying or incivility, which dominate the school context.

The purpose of this study was to determine the ideal concentration of bismuth oxide in white Portland cement to provide it with sufficient radiopacity for use as an endodontic material (ADA specification #57). 2-mm thick standardized test specimens of white MTA and of white Portland cement, as controls, and of white Portland cement with the experimental addition of 5%, 10%, 15%, 20%, 25% or 30% of bismuth oxide were radiographed and compared with various thicknesses of pure aluminum, using optic density to determine the observed grayscale levels of radiopacity in a scale ranging from 0 to 255. The data was submitted to ANOVA (pcement with 0%, 5%, 10%, 15%, 20%, 25% and 30% of bismuth oxide presented mean readings of 63.3, 95.7, 110.7, 142.7, 151.3, 161.0 and 180.0 respectively. MTA presented a mean reading of 157.3. The readings of MTA and white Portland cement with 15% bismuth oxide did not differ significantly from the reading observed for a thickness of 4 mm of aluminum (145.3), which is considered ideal for a test specimen by ADA specification #57 (2 mm above the thickness of the test specimen). White MTA and white Portland cement with 15% bismuth oxide presented the radiopacity required for an endodontic cement.

Changes in public health nursing education have been consideration. Theses changes include a dramatic increase in the number of public health nurses (PHNs) who have enrolled for nursing courses at university. This study was conducted to assess the current status and future of public health nursing education as perceived by teachers and students at three types of schools: universities offering nursing courses, advanced courses for PHNs with junior nursing colleges, and public health nursing schools. Questionnaires were distributed to teachers and students by mail. The questions that were sent to teachers asked which subjects were required to become a certified PHN, which lecture methods were employed to teach public health-particularly community health assessment methods, and what was the level of awareness of the activities of PHNs. Students were asked about their motivation to be a PHN, their understanding of public health, their views of public health activities and their images of PHNs. Responses were analyzed and differences between questionnaires from different schools were noted. These included the number of subjects and the total number of hours spent doing practical training and field experience in universities and the other types of schools, and the number of teachers. Differences also were noted among students at three types of schools about their age, methods of public health activities, knowledge about activities undertaken by PHNs, and their images of PHNs. No differences were observed among the schools with respect to the students' conceptual understanding of public health. Student age, practical training and field experience were found to contribute to their level of understanding of public health and public health nursing. It is thus necessary to consider the teaching methods employed by universities that administer nursing courses and the effectiveness of courses offered by graduate schools.

Tsakiridis, P E; Papadimitriou, G D; Tsivilis, S; Koroneos, C

2008-04-01

The aim of the present research work is to investigate the possibility of adding steel slag, a by-product of the conversion of iron to steel process, in the raw meal for the production of Portland cement clinker. Two samples of raw meals were prepared, one with ordinary raw materials, as a reference sample ((PC)(Ref)), and another with 10.5% steel slag ((PC)(S/S)). Both raw meals were sintered at 1450 degrees C. The results of chemical and mineralogical analyses as well as the microscopic examination showed that the use of the steel slag did not affect the mineralogical characteristics of the so produced Portland cement clinker. Furthermore, both clinkers were tested by determining the grindability, setting times, compressive strengths and soundness. The hydration products were examined by XRD analysis at 2, 7, 28 and 90 days. The results of the physico-mechanical tests showed that the addition of the steel slag did not negatively affect the quality of the produced cement.

Network Level Carbon Dioxide Emissions From On-road Sources in the Portland OR, (USA) Metropolitan Area

Science.gov (United States)

Powell, J.; Butenhoff, C. L.; Rice, A. L.

2014-12-01

To mitigate climate change, governments at multiple levels are developing policies to decrease anthropogenic carbon dioxide (CO2) emissions. The City of Portland (Oregon) and Multnomah County have adopted a Climate Action Plan with a stated goal of reducing emissions to 80% below 1990 levels by 2050. The transportation sector alone accounts for about 40% of total emissions in the Portland metropolitan area. Here we show a new street-level model of on-road mobile CO2 emissions for the Portland, OR metropolitan region. The model uses hourly traffic counter recordings made by the Portland Bureau of Transportation at 9,352 sites over 21 years (1986-2006), augmented with freeway loop detector data from the Portland Regional Transportation Archive Listing (PORTAL) transportation data archive. We constructed a land use regression model to fill in traffic network gaps with traffic counts as the dependent variable using GIS data such as road class (32 categories) and population density. The Environmental Protection Agency (EPA) MOtor Vehicle Emission Simulator (MOVES) model was used to estimate transportation CO2 emissions. The street-level emissions can be aggregated and gridded and used as input to atmospheric transport models for comparison with atmospheric measurements. This model also provides an independent assessment of top-down inventories that determine emissions from fuel sales, while being an important component of our ongoing effort to assess the effectiveness of emission mitigation strategies at the urban scale.

Body mass index (BMI percentiles and z-scores were computed for 4673 students. President's Challenge 1-mile endurance run was completed by 1075 students ages 9-19 years. Maximal oxygen consumption (⩒O2max was predicted using an age-, sex-, and BMI-specific formula to determine health-related fitness. Resting blood pressure (BP was assessed in 1467 students. Regression analyses were used to compare BMI z-scores, fitness, and age- and sex-specific BP percentiles across grade levels. Chi-square tests were used to explore the effect of sex and grade-level on health-related outcomes.Based on BMI, 19.8% were categorized as overweight and 24.4% were obese. Included in the obese category were 454 students (9.7% of sample classified with severe obesity. Using FITNESSGRAM criteria, 50.2% of students did not achieve the Healthy Fitness Zone (HFZ; the proportion of students in the Needs Improvement categories increased from elementary to middle school to high school. Male students demonstrated higher fitness than female students, with 61.4% of boys and only 35.4% of girls meeting HFZ standards. Elevated BP was observed among 24% of 1467 students assessed. Systolic and diastolic BP z-scores revealed low correlation with BMI z-scores.A community-university collaboration identified obesity, severe obesity, overweight, and low aerobic fitness to be common risk factors among urban public school students.

The authors implemented and assessed the effectiveness of a public health initiative aimed at reducing traffic-related air pollution exposure of the school community at four Cincinnati public schools. A partnership was fostered with academic environmental health researchers and community members. Anti-idling campaign materials were developed and education and training were provided to school bus drivers, students, parents, and school staff. Pledge drives and pre- and posteducation assessments were documented to measure the effectiveness of the program. After completing the educational component of the public health initiative, bus drivers (n = 397), community members (n = 53), and staff (n = 214) demonstrated significantly increased knowledge about the health effects of idling (p public health intervention. A community-driven public health initiative can be effective in both 1) enhancing community awareness about the benefits of reducing idling vehicles and 2) increasing active participation in idling reduction. The partnership initially developed has continued to develop toward a sustainable and growing process.

The relevance of Public Health Genomics (PHG) education among public health specialists has been recently acknowledged by the Association of Schools of Public Health in the European Region. The aim of this cross-sectional survey was to assess the prevalence of post-graduate public health schools for medical doctors which offer PHG training in Italy. The directors of the 33 Italian public health schools were interviewed for the presence of a PHG course in place. We stratified by geographical area (North, Centre and South) of the schools. We performed comparisons of categorical data using the chi-squared test. The response rate was 73% (24/33 schools). Among respondents, 15 schools (63%) reported to have at least one dedicated course in place, while nine (38%) did not, with a significant geographic difference. Results showed a good implementation of courses in PHG discipline in Italian post-graduate public health schools. However further harmonization of the training programs of schools in public health at EU level is needed.

Public Health Education: Teaching Epidemiology in High School Classrooms.

Science.gov (United States)

D'Agostino, Emily

2018-03-01

Epidemiology instruction has expanded at the undergraduate level in part because it increases student critical thinking and scientific literacy, promotes students' perception of public health as both practical and relevant, and empowers students as independent, lifelong learners. Why then are more high schools not adopting epidemiology as a course requirement for students? Although prior iterations of high school epidemiology courses are noteworthy for incorporating active and participatory learning, embedding them into existing and continually shifting curricula is challenging and time-consuming, especially for teachers not trained in the field. It also may be argued that currently available epidemiology teaching resources emphasize content rather than thinking skills and therefore do not optimally promote students' personal engagement with, and in-depth understanding of, the mission and goals of public health. I propose a new framework for high school epidemiology that draws from progressive education ideology, including three critical elements: empowerment, authenticity, and transfer. I provide multiple examples to show how this framework has been used across a wide array of settings to hone epidemiology thinking skills in high school students.

Obesity Prevention Interventions in US Public Schools: Are Schools Using Programs That Promote Weight Stigma?

Science.gov (United States)

Kenney, Erica L; Wintner, Suzanne; Lee, Rebekka M; Austin, S Bryn

2017-12-28

Despite substantial research on school-based obesity prevention programs, it is unclear how widely they are disseminated. It is also unknown whether schools use obesity programs that inadvertently promote weight stigma or disordered weight-control behaviors. In spring 2016, we distributed an online survey about school wellness programming to a simple random sample of US public school administrators (N = 247 respondents; 10.3% response rate). We analyzed survey responses and conducted immersion/crystallization analysis of written open-ended responses. Slightly less than half (n = 117, 47.4%) of schools offered any obesity prevention program. Only 17 (6.9%) reported using a predeveloped program, and 7 (2.8%) reported using a program with evidence for effectiveness. Thirty-seven schools (15.0%) reported developing intervention programs that focused primarily on individual students' or staff members' weight rather than nutrition or physical activity; 28 schools (11.3% of overall) used staff weight-loss competitions. School administrators who reported implementing a program were more likely to describe having a program champion and adequate buy-in from staff, families, and students. Lack of funding, training, and time were widely reported as barriers to implementation. Few administrators used educational (n = 12, 10.3%) or scientific (n = 6, 5.1%) literature for wellness program decision making. Evidence-based obesity prevention programs appear to be rarely implemented in US schools. Schools may be implementing programs lacking evidence and programs that may unintentionally exacerbate student weight stigma by focusing on student weight rather than healthy habits. Public health practitioners and researchers should focus on improving support for schools to implement evidence-based programs.

Gougar, M.L.D.; Scheetz, B.E.; Roy, D.M.

1996-01-01

The formation, structure and chemistry of the ettringite and C-S-H phases of Portland cement have been reviewed as they relate to waste ion immobilization. The purpose of this review was to investigate the use of Portland cement as a host for priority metallic pollutants as identified by the Environmental Protection Agency and as a host for radioactive waste ions as identified in 40 CFR 191. Ettringite acts as host to a number of these ions in both the columnar and channel sections of the crystal structure. Substitutions have been made at the calcium, aluminum, hydroxide and sulfate sites. C-S-H also hosts a number of the waste species in both ionic and salt form. Immobilization mechanisms for C-S-H include sorption, phase mixing and substitution. The following ions have not apparently been reported as specifically immobilized by one of these phases: Ag, Am, Np, Pu, Ra, Tc, Th and Sn; however, some of these ions are immobilized by Portland cement

Medical schools, although the gatekeepers of much biomedical education and research, rarely engage formally with K-12 educators to influence curriculum content or professional development. This segregation of content experts from teachers creates a knowledge gap that limits inclusion of current biomedical science into high school curricula, affecting both public health literacy and the biomedical pipeline. The authors describe how, in 2009, scientists from Tufts Medical School and Boston public school teachers established a partnership of formal scholarly dialogue to create 11th- to 12th-grade high school curricula about critical health-related concepts, with the goal of increasing scientific literacy and influencing health-related decisions. The curricula are based on the great diseases (infectious diseases, neurological disorders, metabolic disease, and cancer). Unlike most health science curricular interventions that provide circumscribed activities, the curricula are comprehensive, each filling one full term of in-class learning and providing extensive real-time support for the teacher. In this article, the authors describe how they developed and implemented the infectious disease curriculum, and its impacts. The high school teachers and students showed robust gains in content knowledge and critical thinking skills, whereas the Tufts scientists increased their pedagogical knowledge and appreciation for health-related science communication. The results show how formal interactions between medical schools and K-12 educators can be mutually beneficial.

The goal of the study was to assess public school children at the end of the first stage of elementary school. We used a protocol applied concurrently with a writing test in the form of an unexpected activity in 28 public schools; 2,893 children assessed, 687 exhibited performance below 58 points, 184 were excluded due to change of address or lack of consent; 503 children subjected to a test of intellectual capacity and reading assessment and 71 considered intellectually disabled were excluded. 226 (7.8%) children, who could read, write, and had normal intellectual level, met the criteria of developmental dyscalculia (DD), 98 female and 128 male. The most influential factors in the prevalence were socioeconomic levels of the schools neighborhood, education level of parents, and being male, as demonstrated by the odds ratio and multiple logistic regression analysis. Further studies should be done so that educational policies are taken.

2008-12-01

Full Text Available Effect of admixtures such as black gram pulse (BGP and sulfonated naphthalene based superplasticizer (SP on the hydration of Portland cement has been studied. The hydration characteristics of OPC in the presence of BGP and SP were studied with the help of non evaporable water content determinations, calorimetric method, Mössbauer spectroscopic and atomic force microscopic techniques. Results have shown that both BGP and SP get adsorbed at the surface of cement and its hydration products. The hydration of Portland cement is retarded in the presence of both the admixtures and nanosize hydration products are formed.

Modeling school choice: A comparison of public, private-independent, private-religious and home-schooled students

Directory of Open Access Journals (Sweden)

Clive R. Belfield

2004-06-01

Full Text Available U.S. students now have four choices of schooling: public schooling, private–religious schooling, private–independent schooling, and home-schooling. Of these, home-schooling is the most novel: since legalization across the states in the last few decades, it has grown in importance and legitimacy as an alternative choice. Thus, it is now possible to investigate the motivation for home-schooling, relative to the other schooling options. Here, we use two recent large-scale datasets to assess the school enrollment decision: the first is the National Household Expenditure Survey (1999, and the second is micro-data on SAT test-takers in 2001. We find that, generally, families with home-schoolers have similar characteristics to those with children at other types of school, but mother’s characteristics – specifically, her employment status – have a strong influence on the decision to home-school. Plausibly, religious belief has an important influence on the schooling decision, not only for Catholic students, but also those of other faiths.

The role of schools of public health in capacity building.

Science.gov (United States)

Tulchinsky, Theodore H; Goodman, Julien

2012-08-01

Public health has been an enormously effective instrument for improving life expectancy and quality of life. Historically a sphere of governmental activity led by physicians and staffed by sanitarians and nurses, public health has evolved to become a multi-facetted field of societal activity. It engages many agencies and community action in reducing infectious and non-communicable diseases as well as many aspects of lifestyle and health equity. Education for an adequate professional workforce is one of its key functions. Schools of public health have fulfilled this role only partly even in developed countries, but in countries in transition and in low-income countries the problem is much more acute. We discuss the role of mentoring of new schools calling for strong public and private donor support for this as a key issue in global health.

Properties of Portland-Composite Cements with metakaolin: Commercial and manufactured by Thermal Activation of Serbian Kaolin Clay

2012-09-01

Full Text Available Portland-composite cements (CEM II were prepared with addition of 5 to 35% of metakaolin (MK, manufactured by thermal activation/calcination of Serbian kaolin clay, and commercial matakaolin (CMK. Performance of the composite cements was evaluated, through the setting time (initial and final, compressive strengths (for ages 2, 7, 28, 90 and 180 days and soundness, and compared with control cement (Portland cement – CEM I. Setting time (initial and final is accelerated in Portlandcomposite cements, for both metakaolins used. The acceleration is higher in cement with addition of commercial metakaolin. Lower compressive strength is obtained after 2 days of curing for all Portland-composite cements in comparison with control cement, since pozzolanic reaction still did not show its effect. After 7 days, pozzolanic reaction show its effect, manifested as compressive strength increase of Portland-composite cements with addition of up to 35% of CMK, and 25% in the case of cements with MK. After 28 days compressive strength was higher than that for control cement for cements prepared with addition of CMK, and with addition of up to 25% MK. After 90 days increased compressive strength was noticed with addition of 10 - 20% of CMK, and with 10 and 15% of MK, while after 180 days addition of both metakaolins influences compressive strength decrease. The results of the soundness, 0.5 mm for CEM I, and 1.0 mm in most Portland-composite cements indicate soundness increase with addition of metakaolins. Generally, better performance of Portland-composite cements was obtained with addition of commercial metakaolin, which may be attributed to the differences in the pozzolanic activity of the applied metakaolins, 20.5 MPa and 14.9 MPa for CMK and MK, respectively. By our previous findings pozzolanic activity of the thermally activated clay may be increased by subsequent milling of the metakaolin manufactured by thermal activation process.

Experimental and modeling study of Portland cement paste degradation in boric acid

International Nuclear Information System (INIS)

Benakli, A.; Chomat, L.; Le Bescop, P.; Wall, J.

2015-01-01

In the framework of Spent Fuel Pools (SFP) lifetime studies, an investigation of the Portland cement degradation in boric acid has been requested by the Electric Power Research Institute. The main goal of this study is to identify the physico-chemical degradation mechanisms involved in boric acid media. Both experimental and modeling approaches are considered. Concerning degradation experiments, sample of cement paste are immersed during three and nine months in a boric acid solution at 2400 ppm that is periodically renewed. Boric acid concentration has been chosen to be representative of SFP solution. Results will be confronted with reactive transport numerical calculations performed by the reactive transport code HYTEC associated with a dedicated extended database called Thermoddem. The analysis of degradation solution revealed a main ions release mechanism driven by diffusion especially for calcium, nitrate, sodium and sulfate. Leaching behavior of magnesium seems to be more complex. Decalcification is the major degradation process involved, even if a non-negligible contribution of further cations (Mg 2+ , Na + ) and anions (SO 4 2- ) has been noticed. Analysis of degradation soution also revealed that kinetic of Portland cement paste degradation in boric acid is higher than in pure water, regarding the degraded depths measured and calcium leaching rate. This observation has been confirmed by solid characterization. Microstructure analysis of degraded Portland cement paste showed a global porosity increase in the degraded zone that might be mainly attributed to Portlandite dissolution. An Ettringite reprecipitation in the degraded zone has been suspected but could also be Ettringite-like phases containing boron. The analysis techniques used did not allow us to differentiate it, and no others specific mineral phases containing boron has been identified. Profile pattern by XRD analysis allowed us to identify four zones composing the degraded Portland cement paste

Cullen, Karen Weber; Watson, Kathy; Zakeri, Issa

2008-01-01

We assessed the effect of the Texas Public School Nutrition Policy on middle school student lunchtime food consumption. Three years of lunch food records were collected from middle school students in southeast Texas: baseline (2001-2002), after local district changes (2002-2003), and 1 year after implementation of the Texas Public School Nutrition Policy (2005-2006). Students recorded amount and source of foods and beverages they consumed. Analysis of variance and covariance and nonparametric tests were used to compare intake after the policy change with intake during the 2 previous years. After implementation of the nutrition policy, student lunch consumption of vegetables, milk, and several nutrients increased (protein, fiber, vitamins A and C, calcium, and sodium), and consumption of less desirable items (sweetened beverages, snack chips) decreased, as did percentage of energy from fat. Most of the desired nutrients and foods (vegetables and milk) were obtained from the National School Lunch Program meal. Fewer sweetened beverages, candy, chips, and dessert foods were purchased and consumed, but more of these items were brought from home and purchased from the snack bar. Overall, state school nutrition policies can improve the healthfulness of foods consumed by students at lunch.

Use of red mud as addition for portland cement mortars

International Nuclear Information System (INIS)

Ribeiro, D.V.; Morelli, M.R.

2011-01-01

The aim of the present research work was to investigate the possibility of adding red mud, an alkaline leaching waste that is obtained from bauxite during the Bayer process for alumina production, in the raw meal of Portland cement mortars. The red mud is classified as dangerous, according to NBR 10004/2004, and world while generation reached over 117 million tons/year. This huge production requires high consuming products to be used as incorporation matrix and we studied the influence of red mud addition on the characteristics of cement mortars and concrete. In this paper the properties of Portland cement mortars incorporating high amounts of red mud was evaluated: pH variation, fresh (setting time, workability or normal consistency and water retention), and hardened state (mechanical strength, capillary water absorption, density and apparent porosity). Results seem promising for red mud additions up to 20 wt%. (author)

The Impact of Tobacco-Free School Policies on Youth Smoking Rates in Florida Public School Districts.

Terry, Amanda; Zhang, Ning Jackie

2016-02-01

Developing and implementing policies to curb and prevent youth tobacco use is of the utmost importance. In Florida, public school districts were authorized to develop tobacco-free school policies through an amendment to the Florida Clean Indoor Air Act in 2011. The purpose of this study is to determine the impact of tobacco-free school policies on smoking rates among youth in Florida. Analysis of covariance (ANCOVA) and a multiple regression analysis were used to determine whether the comprehensiveness and enforcement of tobacco-free school policies affect the youth smoking rates within Florida public school districts. The 2010 and 2014 youth smoking rates were calculated based on the Florida Youth Tobacco Survey results. The 2010 youth smoking rate and the inclusion of the enforcement component with provision of cessation resources were statistically significant predictors of the 2014 youth smoking rate. However, the comprehensiveness level of a policy and the inclusion of an enforcement component were not statistically significant predictors. The inclusion of an enforcement component with provision of cessation resources is important in efforts to reduce youth smoking rates. The content of the tobacco-free school policies seems to be less relevant to their effectiveness than the enforcement of the policies. © 2016, American School Health Association.

1984-01-01

The effect of neutron irradiation in samples of Portland cement was evaluated, using the resonance frequency method and pulse velocity of ultra-sound techniques. The samples were divided in three groups: 1) monitoring samples; 2) samples submitted to gamma heating; 3) Irradiated samples. In the sample preparation, it was used the Portland Santa Rita CP 320 cement, and water-cement rate of 0.40 l/Kg. The irradiation was done in the research reactor IEA-R1, at IPEN - CNEN/SP, with an integrated flux of 7.2 x 10 18 n/cm 2 (E approx. 1 MeV). Some damage were detected, due to the neutron flux, and by the thermal effect of gamma heating. (E.G.) [pt

Students of Color and Public Montessori Schools: A Review of the Literature

Directory of Open Access Journals (Sweden)

Mira Debs

2017-05-01

Full Text Available Students of color comprise a majority in public Montessori school enrollments around the United States, and practitioners are often asked for evidence of the Montessori Method’s benefits for these students. This article examines the relevant literature related to the experiences of students of color in public Montessori schools. Research finds Montessori education offers both opportunities and limitations for students of color in attending diverse schools, developing executive functions, achieving academically, accessing early childhood education and culturally responsive education, minimizing racially disproportionate discipline, and limiting overidentification for special education. Public Montessori education’s efficacy with students of color may be limited by several factors: the lack of diversity of the teaching staff and culturally responsive teacher education, schools that struggle to maintain racially diverse enrollments, and the challenge of communicating Montessori’s benefits to families with alternative views of education. The review concludes with directions for future research.

Hydration kinetics modeling of Portland cement considering the effects of curing temperature and applied pressure

International Nuclear Information System (INIS)

Lin Feng; Meyer, Christian

2009-01-01

A hydration kinetics model for Portland cement is formulated based on thermodynamics of multiphase porous media. The mechanism of cement hydration is discussed based on literature review. The model is then developed considering the effects of chemical composition and fineness of cement, water-cement ratio, curing temperature and applied pressure. The ultimate degree of hydration of Portland cement is also analyzed and a corresponding formula is established. The model is calibrated against the experimental data for eight different Portland cements. Simple relations between the model parameters and cement composition are obtained and used to predict hydration kinetics. The model is used to reproduce experimental results on hydration kinetics, adiabatic temperature rise, and chemical shrinkage of different cement pastes. The comparisons between the model reproductions and the different experimental results demonstrate the applicability of the proposed model, especially for cement hydration at elevated temperature and high pressure.

Ecological indices of manufacture of Portland cement clinker and production of the dolomite clinker

Directory of Open Access Journals (Sweden)

Vinnichenko Varvara

2017-01-01

Full Text Available It is shown that the production of dolomite clinker in comparison with that of Portland cement is environmentally appropriate. When calcining dolomite for cementitious binder, the pollution of the atmosphere by carbon dioxide is reduced due to its isolation during decarbonization reactions of calcium carbonates. Reducing fuel consumption for clinker burning provides less carbon dioxide emissions from combustion products. Reducing the firing temperature creates obstacles to the formation of nitrogen oxides. The production of binders from dolomite in comparison with the production of Portland cement helps to protect the environment from contamination

Jadranka Bozikov

2016-06-01

Full Text Available Unlike European Schools of Public Health, whose development was primarily influenced by the medical profession and was linked to the healthcare system, North American Schools of Public Health operate as independent academic institutions engaged in research and education of Public Health specialists. While Public Health has been recognised as a distinctive profession in USA and Canada for almost a century, in many European countries it is not recognized as such and, accordingly, there are no well-defined job positions for graduates. Similarities and differences between the European and American Schools of Public Health are reviewed and the importance of classification of core competences, responsibilities and scope of knowledge required for Public Health practice was pointed out as a prerequisite for accreditation of study curricula. For the professionalization of Public Health in Europe further efforts are needed.

Proximity of public elementary schools to major roads in Canadian urban areas.

Amram, Ofer; Abernethy, Rebecca; Brauer, Michael; Davies, Hugh; Allen, Ryan W

2011-12-21

Epidemiologic studies have linked exposure to traffic-generated air and noise pollution with a wide range of adverse health effects in children. Children spend a large portion of time at school, and both air pollution and noise are elevated in close proximity to roads, so school location may be an important determinant of exposure. No studies have yet examined the proximity of schools to major roads in Canadian cities. Data on public elementary schools in Canada's 10 most populous cities were obtained from online databases. School addresses were geocoded and proximity to the nearest major road, defined using a standardized national road classification scheme, was calculated for each school. Based on measurements of nitrogen oxide concentrations, ultrafine particle counts, and noise levels in three Canadian cities we conservatively defined distances roads as the zone of primary interest. Census data at the city and neighborhood levels were used to evaluate relationships between school proximity to major roads, urban density, and indicators of socioeconomic status. Addresses were obtained for 1,556 public elementary schools, 95% of which were successfully geocoded. Across all 10 cities, 16.3% of schools were located within 75 m of a major road, with wide variability between cities. Schools in neighborhoods with higher median income were less likely to be near major roads (OR per $20,000 increase: 0.81; 95% CI: 0.65, 1.00), while schools in densely populated neighborhoods were more frequently close to major roads (OR per 1,000 dwellings/km²: 1.07; 95% CI: 1.00, 1.16). Over 22% of schools in the lowest neighborhood income quintile were close to major roads, compared to 13% of schools in the highest income quintile. A substantial fraction of students at public elementary schools in Canada, particularly students attending schools in low income neighborhoods, may be exposed to elevated levels of air pollution and noise while at school. As a result, the locations of

The present paper describes a methodology for evaluating impacts of Superfund remedial alternatives on the regional economy in the context of a broader sustainability evaluation. Although economic impact methodology is well established, some applications to Superfund remedial evaluation have created confusion because of seemingly contradictory results. This confusion arises from failure to be explicit about 2 opposing impacts of remediation expenditures: 1) positive regional impacts of spending additional money in the region and 2) negative regional impacts of the need to pay for the expenditures (and thus forgo other expenditures in the region). The present paper provides a template for economic impact assessment that takes both positive and negative impacts into account, thus providing comprehensive estimates of net impacts. The paper also provides a strategy for identifying and estimating major uncertainties in the net impacts. The recommended methodology was applied at the Portland Harbor Superfund Site, located along the Lower Willamette River in Portland, Oregon, USA. The US Environmental Protection Agency (USEPA) developed remedial alternatives that it estimated would cost up to several billion dollars, with construction durations possibly lasting decades. The economic study estimated regional economic impacts-measured in terms of gross regional product (GRP), personal income, population, and employment-for 5 of the USEPA alternatives relative to the "no further action" alternative.

Amram Ofer

2011-12-01

Full Text Available Abstract Background Epidemiologic studies have linked exposure to traffic-generated air and noise pollution with a wide range of adverse health effects in children. Children spend a large portion of time at school, and both air pollution and noise are elevated in close proximity to roads, so school location may be an important determinant of exposure. No studies have yet examined the proximity of schools to major roads in Canadian cities. Methods Data on public elementary schools in Canada's 10 most populous cities were obtained from online databases. School addresses were geocoded and proximity to the nearest major road, defined using a standardized national road classification scheme, was calculated for each school. Based on measurements of nitrogen oxide concentrations, ultrafine particle counts, and noise levels in three Canadian cities we conservatively defined distances Results Addresses were obtained for 1,556 public elementary schools, 95% of which were successfully geocoded. Across all 10 cities, 16.3% of schools were located within 75 m of a major road, with wide variability between cities. Schools in neighborhoods with higher median income were less likely to be near major roads (OR per $20,000 increase: 0.81; 95% CI: 0.65, 1.00, while schools in densely populated neighborhoods were more frequently close to major roads (OR per 1,000 dwellings/km2: 1.07; 95% CI: 1.00, 1.16. Over 22% of schools in the lowest neighborhood income quintile were close to major roads, compared to 13% of schools in the highest income quintile. Conclusions A substantial fraction of students at public elementary schools in Canada, particularly students attending schools in low income neighborhoods, may be exposed to elevated levels of air pollution and noise while at school. As a result, the locations of schools may negatively impact the healthy development and academic performance of a large number of Canadian children.

Full Text Available Abstract This study set out to identify knowledge skills and attitudes required by principals of public secondary schools in Lurambi Sub-county in Kakamega County Kenya for effective financial management. The rationale for focusing on the financial management of public secondary schools was based on evidence in contemporary literature showing that there existed problems in schools over the management of funds because parents complained of financial mismanagement. The main objective of this study was to find outfinancial management in public secondary schools in Kenya. The specific objectives were To find out whether principals of public secondary schools identify and mobilize financial resources for their institutions to find out whether principals draw up budgets for their schools according to priorities of the school needs to find out whether supervision monitoring and control of the budget is carried out by principals of public secondary schools. Therefore there was need to find out ways of ensuring efficient financial management in schools. The study was carried out in public secondary schools in Lurambi Sub-county of Kakamega County covering Lurambi and Municipality. The target population for this study consisted of seventeen 17 principals of public secondary schools seventeen 17 school bursars one hundred and thirty six 136 H.O.Ds and seventeen 17 B.O.G representatives giving a total of one hundred and eighty seven 187 people. Sample population was purposively selected from twelve 12 public secondary schools in Lurambi Sub-county through simple random within the clusters of principals school bursars H.O.Ds representatives of B.O.G. The study adopted a descriptive survey design which helped to establish and describe the knowledge skills and attitudes principals of public secondary schools require for effective performance.

An evaluation of the forces operating on the public schools which might influence their disposition toward the utilization of technology is presented. It is suggested that the wide-ranging technology and know-how generated by the Federally sponsored research and development programs can be adapted and applied to the solution of problems found in education. It is suggested that three major developments in society have great bearing on the utilization of technology in educational programs. The extent to which these factors are manifested and interrelated, and the potential significance of their combined impact are analyzed.

This report summarizes the responses to a mail survey sent to superintendents and other administrators of public school districts. The survey was part of an evaluation project for the USDOE Institutional Conservation Program (ICP). The goal of the project is to identify the most successful energy conservation measures (equipment and activities) available to the institutional buildings sector. To accomplish this goal, four specific research objectives were defined: To determine the impact of the ICP grants program on fostering energy efficiency and saving energy; to determine key characteristics of institutional conservation efforts outside the federal program; To determine the technical, organizational, and Institutional conditions that create the opportunity for energy conservation measures (ECMS) to be most effective; and to identify key technology transfer opportunities. This report focuses on those characteristics of school districts (and the schools within those districts) that might influence the identification, implementation, operation, and impacts of institutional energy conservation efforts. Information about institutional characteristics was gathered through a mail survey of public school districts and private schools. The first mailing resulted in responses from 90 of the 823 public school districts selected through a combination cluster-and-stratification sampling technique and 64 of the 1,700 private schools selected as a stratified random sample. Remaining project resources were used to collect data to achieve a statistically sound sample of a total of 250 public school districts by telephone interviews. In doing so, some questions had to be dropped. Responses from both the mall surveys and the telephone interviews of public school districts were combined into one data set. This report describes results for all 250 districts.

Implementing energy conservation initiatives within public schools, including both behavioral changes as well as building retrofits, can generate cost saving and educational benefits. However, the level of energy efficiency improvements that can be achieved may depend on the socio-economic characteristics of the school or the underlying district. The purpose of this research is to identify and examine the factors that have a role in influencing the adoption of energy-saving practices and/or building retrofits within Oklahoma’s public schools. In order to investigate these factors, a survey was administered to public school administrators across the state. The results illustrate different factors that drive schools to make decisions associated with energy conservation and retrofitting efforts. A comparative analysis between different types of schools (e.g., rural vs. urban, low- vs. high-income) was also conducted to discover the combination of characteristics that are associated with energy-saving measures. The findings could help school administrators and teachers understand how they might adopt new behaviors or technologies. - Highlights: • Energy performance improvements depend on characteristics of a school district. • Districts with environmental science classes more likely to take energy measures. • Cost savings motivated energy measures in high-income/large-population districts. • A cluster analysis revealed geographic patterns of energy saving measures.

Lothenbach, Barbara; Matschei, Thomas; Moeschner, Goeril; Glasser, Fred P.

2008-01-01

The composition of the phase assemblage and the pore solution of Portland cements hydrated between 0 and 60 deg. C were modelled as a function of time and temperature. The results of thermodynamic modelling showed a good agreement with the experimental data gained at 5, 20, and 50 deg. C. At 5 and at 20 deg. C, a similar phase assemblage was calculated to be present, while at approximately 50 deg. C, thermodynamic calculations predicted the conversion of ettringite and monocarbonate to monosulphate. Modelling showed that in Portland cements which have an Al 2 O 3 /SO 3 ratio of > 1.3 (bulk weight), above 50 deg. C monosulphate and monocarbonate are present. In Portland cements which contain less Al (Al 2 O 3 /SO 3 < 1.3), above 50 deg. C monosulphate and small amounts of ettringite are expected to persist. A good correlation between calculated porosity and measured compressive strength was observed

The purpose of this study was to evaluate salary differences between male and female academic radiologists at U.S. medical schools. Laws in several U.S. states mandate public release of government records, including salary information of state employees. From online salary data published by 12 states, we extracted the salaries of all academic radiologists at 24 public medical schools during 2011-2013 (n = 573 radiologists). In this institutional review board-approved cross-sectional study, we linked these data to a physician database with information on physician sex, age, faculty rank, years since residency, clinical trial involvement, National Institutes of Health (NIH) funding, scientific publications, and clinical volume measured by 2013 Medicare payments. Sex difference in salary, the primary outcome, was estimated using a multilevel logistic regression adjusting for these factors. Among 573 academic radiologists, 171 (29.8%) were women. Female radiologists were younger (48.5 vs 51.6 years, p = 0.001) and more likely to be assistant professors (50.9% [87/171] vs 40.8% [164/402], p = 0.026). Salaries between men and women were similar in unadjusted analyses ($290,660 vs $289,797; absolute difference, $863; 95% CI, -$18,363 to $20,090), and remained so after adjusting for age, faculty rank, years since residency, clinical trial involvement, publications, total Medicare payments, NIH funding, and graduation from a highly ranked medical school. Among academic radiologists employed at 24 U.S. public medical schools, male and female radiologists had similar annual salaries both before and after adjusting for several variables known to influence salary among academic physicians.
