The occurrence of foodborne illness outbreaks is increasing in schools, and due to the number of children who consume school meals as the only daily meal, this factor becomes even more worrisome. In this sense, the aim of this study was to evaluate the hygienic-health aspects of Food and Nutrition Units (SFNU) of public schools of Bayeux / PB in relation to the adoption of best practices in school food and nutrition. Data were collected through SFNU checklist during visits to units in 29 schools. The health risk of units evaluated was from regular to very high regarding structure and facilities, hygiene of food handlers, environment and food preparation. It was found that 10.3% of handlers used clean and adequate uniforms, and environment and equipment showed poor conservation status in 75.9% and 89.7% of Units, respectively; control of urban pests and vectors was not effective and cleaning of fresh produce was incorrectly conducted in 51.7% of SFNU of schools evaluated. It could be concluded that the production of meals in SFNU of schools evaluated does not meet the requirements established by the best practices in school food and nutrition.

To determine whether electronic monitoring of hand hygiene and voice prompts can improve hand hygiene and decrease nosocomial infection rates in a surgical intermediate care unit. Three-phase quasi-experimental design. Phase I was electronic monitoring and direct observation; phase II was electronic monitoring and computerized voice prompts for failure to perform hand hygiene on room exit; and phase III was electronic monitoring only. Nine-room, 14-bed intermediate care unit in a university, tertiary-care institution. All patient rooms, utility room, and staff lavatory were monitored electronically. All healthcare personnel including physicians, nurses, nursing support personnel, ancillary staff, all visitors and family members, and any other personnel interacting with patients on the intermediate care unit. All patients with an intermediate care unit length of stay >48 hrs were followed for nosocomial infection. Electronic monitoring during all phases, computerized voice prompts during phase II only. We evaluated a total of 283,488 electronically monitored entries into a patient room with 251,526 exits for 420 days (10,080 hrs and 3,549 patient days). Compared with phase I, hand hygiene compliance in patient rooms improved 37% during phase II (odds ratio, 1.38; 95% confidence interval, 1.04-1.83) and 41% in phase III (odds ratio, 1.41; 95% confidence interval, 1.07-1.84). When adjusting for patient admissions during each phase, point estimates of nosocomial infections decreased by 22% during phase II and 48% during phase III; when adjusting for patient days, the number of infections decreased by 10% during phase II and 40% during phase III. Although the overall rate of nosocomial infections significantly decreased when combining phases II and III, the association between nosocomial infection and individual phase was not significant. Electronic monitoring provided effective ongoing feedback about hand hygiene compliance. During both the voice prompt phase and post

Full Text Available This research aims to compare the perceptions of intermediate and mid-level accounting professional candidates on accounting and financial reporting standards. A significant part of accounting process is carried out by vocational school graduate intermediate and mid-level accounting professionals. However, it can be claimed that adequate education about accounting and financial reporting standards isn’t given in vocational schools although these standards structure the whole accounting process. A survey is conducted over students of the related vocational school in Aksaray University. The results indicate no significant difference on students’ perceptions in terms of their school year, high school type, job or internship experience and intention to perform the profession after graduation. These results can be traced to inadequacy of present curriculums and internship programs which can’t create a difference. Based on the results, the content of internship applications is rearranged and an optional subject named as “Accounting and Reporting Standards” is established.

[Evaluation of the nurse working environment in health and social care intermediate care units in Catalonia].

Bullich-Marín, Ingrid; Miralles Basseda, Ramón; Torres Egea, Pilar; Planas-Campmany, Carme; Juvé-Udina, María Eulalia

A favourable work environment contributes to greater job satisfaction and improved working conditions for nurses, a fact that could influence the quality of patient outcomes. The aim of the study is two-fold: Identifying types of centres, according to the working environment assessment made by nurses in intermediate care units, and describing the individual characteristics of nurses related to this assessment. An observational, descriptive, prospective, cross-sectional, and multicentre study was conducted in the last quarter of 2014. Nurses in intermediate care units were given a questionnaire containing the Practice Environment Scale of the Nursing Work Index (PES-NWI) which assesses five factors of the work environment using 31 items. Sociodemographic, employment conditions, professional and educational variables were also collected. From a sample of 501 nurses from 14 centres, 388 nurses participated (77% response). The mean score on the PES-NWI was 84.75. Nine centres scored a "favourable" working environment and five "mixed". The best valued factor was "work relations" and the worst was "resource provision/adaptation". Rotating shift work, working in several units at the same time, having management responsibilities, and having a master degree were the characteristics related to a better perception of the nursing work environment. In most centres, the working environment was perceived as favourable. Some employment conditions, professional, and educational characteristics of nurses were related to the work environment assessment. Copyright © 2015 SEGG. Publicado por Elsevier España, S.L.U.

Sleep deprivation in hospitalized patients is common and can have serious detrimental effects on recovery from illness. Lavender aromatherapy has improved sleep in a variety of clinical settings, but the effect has not been tested in the intermediate care unit. To determine the effect of inhalation of 100% lavender oil on patients' vital signs and perceived quality of sleep in an intermediate care unit. A randomized controlled pilot study was conducted in 50 patients. Control patients received usual care. The treatment group had 3 mL of 100% pure lavender oil in a glass jar in place at the bedside from 10 pm until 6 am. Vital signs were recorded at intervals throughout the night. At 6 am all patients completed the Richard Campbell Sleep Questionnaire to assess quality of sleep. Blood pressure was significantly lower between midnight and 4 am in the treatment group than in the control group (P = .03) According to the overall mean change score in blood pressure between the baseline and 6 am measurements, the treatment group had a decrease in blood pressure and the control group had an increase; however, the difference between the 2 groups was not significant (P = .12). Mean overall sleep score was higher in the intervention group (48.25) than in the control group (40.10), but the difference was not significant. Lavender aromatherapy may be an effective way to improve sleep in an intermediate care unit.

Eke, Marion; Gardner, Paul L.

1991-12-01

Rapid advances in technology are changing the structure of the workforce. There are elite highly-paid hi-tech occupations and low status poorly-paid jobs. Women are unfortunately more likely to be found in the latter category. To allow them to qualify and compete for the higher-status positions, girls need to participate in the physical sciences and in technology studies. However, they are rarely attracted to them in secondary school, possibly because they are already alienated from them by the time they leave primary school. This paper reports some of the outcomes of a curriculum unit taught in two primary school classes in an independent school for girls. The unit was cross-curricular, involving technology, science and other fields of knowledge; it made extensive use of LEGO Technic materials. The evaluation of the unit, based on observations, a teacher journal and pupil questionnaires, focussed upon the issue of whether it assisted the girls to feel happier about working with unfamiliar technology and feel more capable of doing so. Implications for teaching technology are also discussed.

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

Lu, Peng-jun; Byrd, Kathy K.; Murphy, Trudy V.

2018-01-01

Background Since 1996, hepatitis A vaccine (HepA) has been recommended for adults at increased risk for infection including travelers to high or intermediate hepatitis A endemic countries. In 2009, travel outside the United States and Canada was the most common exposure nationally reported for persons with hepatitis A virus (HAV) infection. Objective To assess HepA vaccination coverage among adults 18–49 years traveling to a country of high or intermediate endemicity in the United States. Methods We analyzed data from the 2010 National Health Interview Survey (NHIS), to determine self-reported HepA vaccination coverage (≥1 dose) and series completion (≥2 dose) among persons 18–49 years who traveled, since 1995, to a country of high or intermediate HAV endemicity. Multivariable logistic regression and predictive marginal analyses were conducted to identify factors independently associated with HepA vaccine receipt. Results In 2010, approximately 36.6% of adults 18–49 years reported traveling to high or intermediate hepatitis A endemic countries; among this group unadjusted HepA vaccination coverage was 26.6% compared to 12.7% among non-travelers (P-values hepatitis A endemicity was associated with higher likelihood of HepA vaccination in 2010 among adults 18–49 years, self-reported HepA vaccination coverage was low among adult travelers to these areas. Healthcare providers should ask their patients’ upcoming travel plans and recommend and offer travel related vaccinations to their patients. PMID:23523408

Frontiers in Microbiology: Envisioning a Curriculum Unit for High School Biology

Energy Technology Data Exchange (ETDEWEB)

Mark Bloom

2004-06-18

Microbiology is undergoing a quiet revolution. Techniques such as polymerase chain reaction, high throughput DNA sequencing, whole genome shotgun sequencing, DNA microarrays, and bioinformatics analyses are greatly aiding our understanding of the estimated one billion species of microbes that inhabit the Earth. Unfortunately, the rapid pace of research in microbiology stands in contrast to the much slower pace of change in educational reform. Biological Sciences Curriculum Study (BSCS) hosted a two-day planning meeting to discuss whether or not a new curriculum unit on microbiology is desirable for the high school audience. Attending the meeting were microbiologists, high school biology teachers, and science educators. The consensus of the participants was that an inquiry-based unit dealing with advances in microbiology should be developed for a high school biology audience. Participants established content priorities for the unit, discussed the unit's conceptual flow, brainstormed potential student activities, and discussed the role of educational technology for the unit. As a result of the planning meeting discussions, BSCS staff sought additional funding to develop, disseminate, and evaluate the Frontiers in Microbiology curriculum unit. This unit was intended to be developed as a replacement unit suitable for an introductory biology course. The unit would feature inquiry-based student activities and provide approximately four weeks of instruction. As appropriate, activities would make use of multimedia. The development and production processes would require about two years for completion. Unfortunately, BSCS staff was not able to attract sufficient funding to develop the proposed curriculum unit. Since there were some unexpended funds left over from the planning meeting, BSCS requested and received permission from DOE to use the balance of the funds to prepare background materials about advances in microbiology that would be useful to teachers.

Wheaton, Anne G; Jones, Sherry Everett; Cooper, Adina C; Croft, Janet B

2018-01-26

Insufficient sleep among children and adolescents is associated with increased risk for obesity, diabetes, injuries, poor mental health, attention and behavior problems, and poor academic performance (1-4). The American Academy of Sleep Medicine has recommended that, for optimal health, children aged 6-12 years should regularly sleep 9-12 hours per 24 hours and teens aged 13-18 years should sleep 8-10 hours per 24 hours (1). CDC analyzed data from the 2015 national, state, and large urban school district Youth Risk Behavior Surveys (YRBSs) to determine the prevalence of short sleep duration (school nights among middle school and high school students in the United States. In nine states that conducted the middle school YRBS and included a question about sleep duration in their questionnaire, the prevalence of short sleep duration among middle school students was 57.8%, with state-level estimates ranging from 50.2% (New Mexico) to 64.7% (Kentucky). The prevalence of short sleep duration among high school students in the national YRBS was 72.7%. State-level estimates of short sleep duration for the 30 states that conducted the high school YRBS and included a question about sleep duration in their questionnaire ranged from 61.8% (South Dakota) to 82.5% (West Virginia). The large percentage of middle school and high school students who do not get enough sleep on school nights suggests a need for promoting sleep health in schools and at home and delaying school start times to permit students adequate time for sleep.

Persons from the United States who travel to developing countries are at substantial risk for hepatitis B virus (HBV) infection. Hepatitis B vaccine has been recommended for adults at increased risk for infection, including travelers to high or intermediate hepatitis B endemic countries. To assess hepatitis B vaccination coverage among adults ≥18 years traveling to a country of high or intermediate endemicity from the United States. Data from the 2015 National Health Interview Survey (NHIS) were analyzed to determine hepatitis B vaccination coverage (≥1 dose) and series completion (≥3 doses) among persons aged ≥18 years who reported traveling to a country of high or intermediate hepatitis B endemicity. Multivariable logistic regression and predictive marginal analyses were conducted to identify factors independently associated with hepatitis B vaccination. In 2015, hepatitis B vaccination coverage (≥1 dose) among adults aged ≥18 years who reported traveling to high or intermediate hepatitis B endemic countries was 38.6%, significantly higher compared with 25.9% among non-travelers. Series completion (≥3 doses) was 31.7% and 21.2%, respectively (P travel status was significantly associated with hepatitis B vaccination coverage and series completion. Other characteristics independently associated with vaccination (≥1 dose, and ≥3 doses) among travelers included age, race/ethnicity, educational level, duration of US residence, number of physician contacts in the past year, status of ever being tested for HIV, and healthcare personnel status. Although travel to a country of high or intermediate hepatitis B endemicity was associated with higher likelihood of hepatitis B vaccination, hepatitis B vaccination coverage was low among adult travelers to these areas. Healthcare providers should ask their patients about travel plans and recommend and offer travel related vaccinations to their patients or refer them to alternate sites for vaccination

2015-01-01

Substantial interest has begun to emerge around the implementation of yoga interventions in schools. Researchers have found that yoga practices may enhance skills such as self-regulation and prosocial behavior, and lead to improvements in students' performance. These researchers, therefore, have proposed that contemplative practices have the potential to play a crucial role in enhancing the quality of US public education. The purpose of the present study was to provide a summary and comparison of school-based yoga programs in the United States. Online, listserv, and database searches were conducted to identify programs, and information was collected regarding each program's scope of work, curriculum characteristics, teacher-certification and training requirements, implementation models, modes of operation, and geographical regions. The online, listserv, and database searches took place in Boston, MA, USA, and New Haven, CT, USA. Thirty-six programs were identified that offer yoga in more than 940 schools across the United States, and more than 5400 instructors have been trained by these programs to offer yoga in educational settings. Despite some variability in the exact mode of implementation, training requirements, locations served, and grades covered, the majority of the programs share a common goal of teaching 4 basic elements of yoga: (1) physical postures, (2) breathing exercises, (3) relaxation techniques, and (4) mindfulness and meditation practices. The programs also teach a variety of additional educational, social-emotional, and didactic techniques to enhance students' mental and physical health and behavior. The fact that the present study was able to find a relatively large number of formal, school-based yoga programs currently being implemented in the United States suggests that the programs may be acceptable and feasible to implement. The results also suggest that the popularity of school-based yoga programs may continue to grow.

Despite some variability in the exact mode of implementation, training requirements, locations served, and grades covered, the majority of the programs share a common goal of teaching 4 basic elements of yoga: (1) physical postures, (2) breathing exercises, (3) relaxation techniques, and (4) mindfulness and meditation practices. The programs also teach a variety of additional educational, social-emotional, and didactic techniques to enhance students’ mental and physical health and behavior. Conclusions The fact that the present study was able to find a relatively large number of formal, school-based yoga programs currently being implemented in the United States suggests that the programs may be acceptable and feasible to implement. The results also suggest that the popularity of school

Motor-vehicle crashes are a leading cause of death among children in the United States, and almost one-fourth of all trips by school-aged children are trips to and from school. This study sought to determine how children (5-18years) travel to and from school and, among those living ≤1mile of school, to explore the role of school bus service eligibility on school travel mode. We used national 2012 survey data to determine prevalence of usual school travel mode, stratified by distance from school. For those living ≤1mile of school, multivariable regression was conducted to assess the association between bus service eligibility and walking or bicycling. Almost half (46.6%) of all children rode in passenger vehicles (PV) to school and 41.8% did so for the trip home. Results were similar among those living ≤1mile (48.1%, PV to school; 41.3%, PV to home). Among those living ≤1mile, 21.9% and 28.4% of children walked or bicycled to and from school, respectively. Ineligibility for school bus service was strongly associated with walking or bicycling to school [adjusted prevalence ratio (aPR: 5.36; ppassenger vehicles were a common mode of travel. For children who live close to school, the role that school bus service eligibility plays in walking or bicycling deserves further consideration. Given the large proportion of children who use passenger vehicles for school travel, effective interventions can be adopted to increase proper child restraint and seat belt use and reduce crash risks among teen drivers. Better understanding of conditions under which bus service is offered to children who live close to school could inform efforts to improve pedestrian and bicyclist safety for school travel.

Persons from the United States who travel to developing countries are at substantial risk for hepatitis B virus (HBV) infection. Hepatitis B vaccine has been recommended for adults at increased risk for infection, including travelers to high or intermediate hepatitis B endemic countries. To assess hepatitis B vaccination coverage among adults ≥ 18 years traveling to a country of high or intermediate endemicity from the United States. Data from the 2015 National Health Interview Survey (NHIS) were analyzed to determine hepatitis B vaccination coverage (≥1 dose) and series completion (≥3 doses) among persons aged ≥ 18 years who reported traveling to a country of high or intermediate hepatitis B endemicity. Multivariable logistic regression and predictive marginal analyses were conducted to identify factors independently associated with hepatitis B vaccination. In 2015, hepatitis B vaccination coverage (≥1 dose) among adults aged ≥ 18 years who reported traveling to high or intermediate hepatitis B endemic countries was 38.6%, significantly higher compared with 25.9% among non-travelers. Series completion (≥3 doses) was 31.7% and 21.2%, respectively (P travel status was significantly associated with hepatitis B vaccination coverage and series completion. Other characteristics independently associated with vaccination (≥1 dose, and ≥ 3 doses) among travelers included age, race/ethnicity, educational level, duration of U.S. residence, number of physician contacts in the past year, status of ever being tested for HIV, and healthcare personnel status. Although travel to a country of high or intermediate hepatitis B endemicity was associated with higher likelihood of hepatitis B vaccination, hepatitis B vaccination coverage was low among adult travelers to these areas. Healthcare providers should ask their patients about travel plans and recommend and offer travel related vaccinations to their patients or refer them to alternate

Despite the public alarm following a series of high-profile school shootings that occurred in the United States during the late 1990s, little is known about the actual incidence and characteristics of school-associated violent deaths. To describe recent trends and features of school-associated violent deaths in the United States. Population-based surveillance study of data collected from media databases, state and local agencies, and police and school officials for July 1, 1994, through June 30, 1999. A case was defined as a homicide, suicide, legal intervention, or unintentional firearm-related death of a student or nonstudent in which the fatal injury occurred (1) on the campus of a public or private elementary or secondary school, (2) while the victim was on the way to or from such a school, or (3) while the victim was attending or traveling to or from an official school-sponsored event. National estimates of risk of school-associated violent death; national trends in school-associated violent deaths; common features of these events; and potential risk factors for perpetration and victimization. Between 1994 and 1999, 220 events resulting in 253 deaths were identified; 202 events involved 1 death and 18 involved multiple deaths (median, 2 deaths per multiple-victim event). Of the 220 events, 172 were homicides, 30 were suicides, 11 were homicide-suicides, 5 were legal intervention deaths, and 2 were unintentional firearm-related deaths. Students accounted for 172 (68.0%) of these deaths, resulting in an estimated average annual incidence of 0.068 per 100 000 students. Between 1992 and 1999, the rate of single-victim student homicides decreased significantly (P =.03); however, homicide rates for students killed in multiple-victim events increased (P =.047). Most events occurred around the start of the school day, the lunch period, or the end of the school day. For 120 (54.5%) of the incidents, respondents reported that a note, threat, or other action potentially

We find a robust negative relation between years of schooling and fertility. The magnitude of our baseline estimate suggests that the rise in schooling accounts...... for about 60% of the US fertility decline. In contrast, we find no evidence of a robust relation between income per capita and fertility. This pattern corroborates theories stressing the importance of human capital investments in generating a transition from high to low fertility....

Barriers to children walking and biking to school--United States, 1999.

Science.gov (United States)

2002-08-16

Physical activity is an important part of a healthy lifestyle; however, many children in the United States do not meet recommended levels of physical activity. Although walking and biking to school can increase physical activity among children, motor-vehicle traffic and other factors can make these activities difficult. The majority of U.S. children do not walk or bike to school, approximately one third ride a school bus, and half are driven in a private vehicle. Less than one trip in seven is made by walking or biking. To examine why the majority of children do not walk or bike to school, CDC analyzed data from the national HealthStyles Survey. This report summarizes the results of that analysis, which indicate that long distances and dangerous motor-vehicle traffic pose the most common barriers to children walking and biking to school. Public health and community-based efforts that encourage walking and biking to school should address these barriers.

The reaction intermediates in the carbothermal reduction and nitridation (CRN) reaction of γ-Al 2 O 3 were identified by 27 Al magic-angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopy. This identification ruled out the possibility of a reaction mechanism involving the gaseous reaction intermediates. In the CRN reaction of γ-Al 2 O 3 , AlO 4 units were converted to AlN stepwise via AlN x O 4-x (x = 1, 2, 3) intermediates, while AlO 6 units were more slowly converted to AlN than AlO 4 units and the NMR peaks of partially nitridated AlO 6 units were not detected. The NMR peak intensities of partially nitridated AlO 4 units became weaker with increasing reaction temperature.

Sport-related concussion affects athletes at every level of participation. The short and long-term effects of concussions that occur during childhood and adolescence are not fully understood. The purpose of this review is to describe the current burden of disease, current practice patterns and current recommendations for the assessment and management of sport-related concussions sustained by United States high school athletes. Millions of high school students participate in organized sports in the United States. Current estimates suggest that, across all sports, approximately 2.5 concussions occur for every 10 000 athletic exposures, in which an athletic exposure is defined as one athlete participating in one game or practice. At schools that employ at least one athletic trainer, most high school athletes who sustain sport-related concussions will be cared for by athletic trainers and primary care physicians. Approximately 40% will undergo computerized neurocognitive assessment. The number of high school athletes being diagnosed with sport-related concussions is rising. American football has the highest number of concussions in high school with girls' soccer having the second highest total number. Fortunately, coaches are becoming increasingly aware of these injuries and return-to-play guidelines are being implemented.

The MHD intermediate shock interaction with an intermediate wave: Are intermediate shocks physical?

International Nuclear Information System (INIS)

Wu, C.C.

1988-01-01

Contrary to the usual belief that MHD intermediate shocks are extraneous, the authors have recently shown by numerical solutions of dissipative MHD equations that intermediate shocks are admissible and can be formed through nonlinear steepening from a continuous wave. In this paper, he clarifies the differences between the conventional view and the results by studying the interaction of an MHD intermediate shock with an intermediate wave. The study reaffirms his results. In addition, the study shows that there exists a larger class of shocklike solutions in the time-dependent dissiaptive MHD equations than are given by the MHD Rankine-Hugoniot relations. it also suggests a mechanism for forming rotational discontinuities through the interaction of an intermediate shock with an intermediate wave. The results are of importance not only to the MHD shock theory but also to studies such as magnetic field reconnection models

Characteristics of bank financial intermediation in Croatian counties

Directory of Open Access Journals (Sweden)

Jakša Krišto

2015-03-01

Full Text Available Research on bank financial intermediation in a country’s narrower territorial units is scarce, in both domestic and international literature. Banks are almost the only financial intermediaries in narrower territorial units and their role is substantial, ranging from participating in regional development to the successful running of their own business. Hence, the main objective of this paper is to examine the characteristics of the financial intermediation of banks in the counties of the Republic of Croatia, both through a comparison between their economic development levels and the general presence of financial intermediation, and a more specific analysis of their deposit and credit policies. The article uses hierarchical and non-hierarchical (k-means cluster analyses to identify relatively homogeneous groups of counties based on sets of indicators of: economic environment, financial development and infrastructure and, at a more detailed level, the deposit and credit policies of banks. The research results suggest heterogeneity and diversity of bank policies across the counties and sets of indicators. Differences have been observed between developed and developing counties, as well as in approaches to banks’ deposit and credit policies. The paper’s findings encourage further research into these issues.

Local school districts are often one of the largest, if not the largest, employers in their respective communities. Like many large employers, school districts offer health insurance to their employees. There is a lack of information about the rate of health insurance premiums in US school districts relative to other employers. To assess the change in the costs of healthcare insurance in the 5 largest public school districts in the United States, between 2004 and 2008, as representative of large public employers in the country. Data for this study were drawn exclusively from a survey sent to the 5 largest public school districts in the United States. The survey requested responses on 3 data elements for each benefit plan offered from 2004 through 2008; these included enrollment, employee costs, and employer costs. The premium growth for the 5 largest school districts has slowed down and is consistent with other purchasers-Kaiser/Health Research & Educational Trust and the Federal Employee Health Benefit Program. The average increase in health insurance premium for the schools was 5.9% in 2008, and the average annual growth rate over the study period was 7.5%. For family coverage, these schools provide the most generous employer contribution (80.8%) compared with the employer contribution reported by other employers (73.5%) for 2008. Often the largest employers in their communities, school districts demonstrate a commitment to provide choice of benefits and affordability for employees and their families. Despite constraints typical of public employers, the 5 largest school districts in the United States have decelerated in premium growth consistent with other purchasers, albeit at a slower pace.

The light intensity of a light-curing unit is a crucial factor that affects the clinical longevity of resin composites. This study aimed to investigate the efficiency of light-curing units in use at a local governmental dental school for curing conventional and bulk-fill resin materials. A total of 166 light-curing units at three locations were examined, and the brand, type, clinic location, diameter of curing tip, tip cleanliness (using a visual score), and the output (in mW/cm 2 using a digital radiometer) were recorded. Only 23.5% of the units examined had clean tips, with the graduate student clinical area containing the highest percentage of clean tips. Further, tips with poor cleanliness score values were associated with significantly lower output intensities. A small percentage (9.4%) of units was capable of producing intensities higher than 1,200 mW/cm 2 and lower than 600 mW/cm 2 (7.6%). The majority of the low intensity units were located in the undergraduate student area, which also contained the highest number of units with intensities between 900 and 1,200 mW/cm 2 . The output of all the units in service was satisfactory for curing conventional resin composites, and most units were capable of curing bulk-fill resin materials.

To identify trends in medical school otolaryngology curriculum requirements. Survey of United States allopathic medical schools. A survey was sent to deans of curriculum at allopathic medical schools. We identified opportunities for medical students to learn basic concepts in otolaryngology during their undergraduate medical training. The opportunities were classified into preclinical and clinical as well as elective and mandatory rotations. Of the schools surveyed, 60% responded. Mean class size was 149 students. Sixty-eight percent of surveyed schools noted that 75% to 100% of their students participated in preclinical otolaryngology experiences, with 59% reporting a mandatory preclinical otolaryngology module for all students. Eighty-nine percent of schools offered otolaryngology as a clinical elective rotation, with a mean of 12 students participating yearly. Only 7% of schools required a mandatory otolaryngology clinical rotation. Our data suggest that medical students do not receive sufficient exposure to otolaryngology during medical school. Increased requirements for otolaryngology curriculum may be beneficial to all medical students, regardless of their specialty choice. NA.

Dietary intake among children in the United States falls short of national recommendations. Schools can play an important role in improving children's preferences and food consumption patterns. The US Department of Agriculture's Fresh Fruit and Vegetable Program (FFVP) aims to improve children's nutrient intake patterns by offering fresh fruits and vegetables as snacks outside the reimbursable meals programs in elementary schools that serve large numbers of low-income children. Using a nationally representative sample of public elementary schools, this cross-sectional study investigated FFVP participation patterns among schools by demographic and school characteristics. Further, the study investigated the association between FFVP participation and availability of fresh fruits, salads, and vegetables at lunch as reported by school administrators and foodservice staff. Data collected via a mail-back survey from 620 public elementary schools participating in the National School Lunch Program during 2009-2010 were analyzed. Almost 70% of the FFVP-participating schools had a majority of students (>50%) eligible for free and reduced-cost meals. Participating in US Department of Agriculture Team Nutrition Program and having a registered dietitian or a nutritionist on staff were significantly associated with FFVP participation. Based on the results from logistic regression analyses schools participating in the FFVP were significantly more likely (odds ratio 2.07; 95% CI 1.12 to 3.53) to serve fresh fruit during lunch meals. Slightly >25% of public elementary schools across the United States participated in the FFVP, and participation was associated with healthier food availability in school lunches.

Lee, Clark J; Nolan, Dennis M; Lockley, Steven W; Pattison, Brent

2017-12-01

The increasing scientific evidence that early school start times are harmful to the health and safety of teenagers has generated much recent debate about changing school start times policies for adolescent students. Although efforts to promote and implement such changes have proliferated in the United States in recent years, they have rarely been supported by law-based arguments and messages that leverage the existing legal infrastructure regulating public education and child welfare in the United States. Furthermore, the legal bases to support or resist such changes have not been explored in detail to date. This article provides an overview of how law-based arguments and messages can be constructed and applied to advocate for later school start time policies in US public secondary schools. The legal infrastructure impacting school start time policies in the United States is briefly reviewed, including descriptions of how government regulates education, what legal obligations school officials have concerning their students' welfare, and what laws and public policies currently exist that address adolescent sleep health and safety. On the basis of this legal infrastructure, some hypothetical examples of law-based arguments and messages that could be applied to various types of advocacy activities (eg, litigation, legislative and administrative advocacy, media and public outreach) to promote later school start times are discussed. Particular consideration is given to hypothetical arguments and messages aimed at emphasizing the consistency of later school start time policies with existing child welfare law and practices, legal responsibilities of school officials and governmental authorities, and societal values and norms.

Determination Bounds for Intermediate Products in a Two-Stage Network DEA

Directory of Open Access Journals (Sweden)

Hadi Bagherzadeh Valami

2016-03-01

Full Text Available The internal structure of decision making unit (DMU is the key element at extension of network DEA. In general considering internal performance evaluation of system is a better criterion than the conventional DEA-models, essentially based on the initial inputs and final outputs of the system. The internal performance of a system is dependent on the relation between sub-DMUs and intermediate products. Since the intermediate measures are consumed by some sub-DMUs produced by the others, it is possible to produce systems; the role of intermediate production is twice output and input. That's why they can be analyzed based on conventional mathematical modeling. In this paper we introduce a new method for determining bounds for intermediate product in a two stage network DEA structure.

New medical schools in the United States: forces of change past and present.

Science.gov (United States)

Smith, Lawrence

2009-01-01

The new millennium has ushered in a growth phase in the number of American medical schools. Historically the United States has built schools during bursts of activity with relative quiescence in between these periods. We had a twenty-two year period with no growth in medical school size or number. During that time there were significant changes in patient characteristics, student culture, financial reimbursement, quality, and manpower needs that have put stress on medical schools, hospitals, clinical practice and healthcare systems. In addition, there have been remarkable new opportunities in the way we teach, including changes in teaching methodology, educational technology, and a better understanding of how students actually learn. All of these advances have taken place during a period of enormous pressure to change residency programs, reorganize medical and clinical science, and question the very need for traditional departmental structures. It is likely that the new medical schools will emerge looking different from the older schools and they are likely to catalyze a period of curricular change.

State-of-the-art neutron and x-ray diffraction measurements have been performed to provide a definitive picture of the intermediate- and short-range structures of P x Se 1-x glasses spanning two glass regions, x 0.025-0.54 and 0.64-0.84. Liquid P 4 Se 3 and amorphous red P and Se were also measured. Detailed information was obtained about the development with increasing phosphorous concentration of intermediate-range order on the length scale ∼6 A ring , based on the behavior of the first sharp diffraction peak. Attention is also paid to the feature in the structure factor at 7.5 A ring -1 , identified in earlier numerical simulations, provides further evidence of the existence of molecular units. The real-space transforms yield a reliable statistical picture of the changing short-range order as x increases, using the information about types and concentrations of local structural units provided by previous NMR measurements to interpret the trends observed.

Student and school factors associated with school suspension: A multilevel analysis of students in Victoria, Australia and Washington State, United States

One of the common issues schools face is how best to handle challenging student behaviors such as violent behavior, antisocial behavior, bullying, school rule violations, and interrupting other students’ learning. School suspension may be used to remove students engaging in challenging behaviors from the school for a period of time. However, the act of suspending students from school may worsen rather than improve their behavior. Research shows that suspensions predict a range of student outcomes, including crime, delinquency, and drug use. It is therefore crucial to understand the factors associated with the use of school suspension, particularly in sites with different policy approaches to problem behaviors. This paper draws on data from state-representative samples of 3,129 Grade 7 and 9 students in Washington State, United States and Victoria, Australia sampled in 2002. Multilevel modeling examined student and school level factors associated with student-reported school suspension. Results showed that both student (being male, previous student antisocial and violent behavior, rebelliousness, academic failure) and school (socioeconomic status of the school, aggregate measures of low school commitment) level factors were associated with school suspension and that the factors related to suspension were similar in the two states. The implications of the findings for effective school behavior management policy are that, rather than focusing only on the student, both student and school level factors need to be addressed to reduce the rates of school suspension.

Suicide attempts and physical fighting among high school students--United States, 2001.

Science.gov (United States)

2004-06-11

Violence is a major cause of morbidity and mortality, particularly among youths. In the United States, homicide and suicide are the second and third leading causes of death, respectively, for persons aged 13-19 years. Although suicide commonly is associated with anxiety, depression, and social withdrawal, research suggests a link between violent behaviors directed at oneself (i.e., suicidal behaviors) and violent behaviors directed at others among adolescents. Certain students who engage in extreme forms of violence, such as school shootings, exhibit suicidal ideation or behavior before or during the attack. However, suicidal behavior also might be associated with involvement in less extreme forms of violent behaviors, such as physical fighting, which might be a risk factor for more severe forms of violence. To characterize any potential association between suicide attempts and fighting, CDC analyzed self-reported 2001 data from a nationally representative sample of high school students in the United States. The results of that analysis indicated that students who reported attempting suicide during the preceding 12 months were nearly four times more likely also to have reported fighting than those who reported not attempting suicide. Prevention programs that seek to reduce both suicidal and violent behaviors are needed. Because prevalence of this association was determined to be highest in the 9th grade, these efforts might be most effective if implemented before students reach high school.

The Child and Adolescent Trial for Cardiovascular Health (CATCH) was the largest school-based field trial ever sponsored by the National Institutes of Health. The trial demonstrated positive changes in the school food service and physical education program, as well as in students' cardiovascular health behaviors. Because the CATCH intervention programs were implemented in 56 schools (in four states) that were typical of schools throughout the United States, their reception by schools and degree of implementation provide evidence about their feasibility for schools nationally. Extensive process evaluation data were collected from students, teachers, school food service personnel, and physical education specialists throughout the three school years of the CATCH intervention. Four of the CATCH programs--school food service, physical education, classroom curricula, and home programs--were assessed over the three school years. The process data provide information on participation, dose, fidelity, and compatibility of the CATCH programs in the intervention schools for these programs. High levels of participation, dose, fidelity, and compatibility were observed for the four programs during the 3 school years. CATCH emerges as a model of a feasible multilevel health promotion program to improve eating and exercise behaviors for elementary schools in the United States.

Paredes, L.C.; Ortiz, J.R.; Sanchez, S.

2002-01-01

Currently, it is necessary to establish, in a few years, a definitive repository for low and intermediate level radioactive waste in order to satisfy the necessities of Mexico for the next 50 years. Consequently, it is required to estimate the volumes of the radioactive waste generated annually, the stored volumes to-date and their projection to medium-term. On this subject, the annual average production of low and intermediate level radioactive waste from the electricity production by means of nuclear power reactors is 250 m 3 /y which consist of humid and dry solid waste from the 2 units of the Laguna Verde Nuclear Power plant having a re-use efficiency of effluents of 95%. On the other hand, the applications in medicine, industry and research generate 20 m 3 /y of solid waste, 280 m 3 /y of liquid waste and approximately 10 m 3 /y from 300 spent sealed radioactive sources. The estimation of the total volume of these waste to the year 2035 is 17500 m 3 corresponding to the 46% of the volume generated by the operation and maintenance of the 2 units of the Laguna Verde Nuclear Power plant, 34% to the decommissioning of these 2 units at the end of their useful life and 20% to the waste generated by applications in medicine, industry and research.

Designing an educative curriculum unit for teaching molecular geometry in high school chemistry

Science.gov (United States)

Makarious, Nader N.

Chemistry is a highly abstract discipline that is taught and learned with the aid of various models. Among the most challenging, yet a fundamental topic in general chemistry at the high school level, is molecular geometry. This study focused on developing exemplary educative curriculum materials pertaining to the topic of molecular geometry. The methodology used in this study consisted of several steps. First, a diverse set of models were analyzed to determine to what extent each model serves its purpose in teaching molecular geometry. Second, a number of high school teachers and college chemistry professors were asked to share their experiences on using models in teaching molecular geometry through an online questionnaire. Third, findings from the comparative analysis of models, teachers’ experiences, literature review on models and students’ misconceptions, the curriculum expectations of the Next Generation Science Standards and their emphasis on three-dimensional learning and nature of science (NOS) contributed to the development of the molecular geometry unit. Fourth, the developed unit was reviewed by fellow teachers and doctoral-level science education experts and was revised to further improve its coherence and clarity in support of teaching and learning of the molecular geometry concepts. The produced educative curriculum materials focus on the scientific practice of developing and using models as promoted in the Next Generations Science Standards (NGSS) while also addressing nature of science (NOS) goals. The educative features of the newly developed unit support teachers’ pedagogical knowledge (PK) and pedagogical content knowledge (PCK). The unit includes an overview, teacher’s guide, and eight detailed lesson plans with inquiry oriented modeling activities replete with models and suggestions for teachers, as well as formative and summative assessment tasks. The unit design process serves as a model for redesigning other instructional units in

Full Text Available School environments influence student food choices. À la carte foods and beverages are often low nutrient and energy dense. This study assessed how much money students spent for these foods, and the total kilocalories purchased per student during the 2012–2013 school year. Six elementary and four intermediate schools in the Houston area provided daily food purchase transaction data, and the cost and the calories for each item. Chi-square analysis assessed differences in the number of students purchasing à la carte items by grade level and school free/reduced-price meal (FRP eligibility. Analysis of covariance assessed grade level differences in cost and calories of weekly purchases, controlling for FRP eligibility. Intermediate grade students spent significantly more on à la carte food purchases and purchased more calories (both p < 0.001 than elementary school students. Lower socioeconomic status (SES elementary and intermediate school students purchased fewer à la carte foods compared to those in higher SES schools (p < 0.001. Intermediate school students purchased more à la carte foods and calories from à la carte foods than elementary students. Whether the new competitive food rules in schools improve student food selection and purchase, and dietary intake habits across all grade levels remains unknown.

Full Text Available We consider a production-inventory system that consists of an input-generating installation, a production unit and L intermediate buffers. It is assumed that the installation transfers the raw material to buffer and the production unit pulls the raw material from buffer We consider the problem of the optimal preventive maintenance of the installation if the installation deteriorates stochastically with usage and the production unit is always in operative condition. We also consider the problem of the optimal preventive maintenance of the production unit if the production unit deteriorates stochastically with usage and the installation is always in operative condition. Under a suitable cost structure and for given contents of the buffers, it is proved that the average-cost optimal policy for the first (second problem initiates a preventive maintenance of the installation (production unit if and only if the degree of deterioration of the installation (production unit exceeds some critical level. Numerical results are presented for both problems.

2014-12-14

Charge generation in a typical intermediate connector, composed of “n-type doped layer/transition metal oxide (TMO)/hole transporting layer (HTL),” of a tandem organic light-emitting device (OLED) has recently been found to arise from charge transfer at the TMO/HTL interfaces. In this paper, we investigate the effect of hole injection barriers from intermediate connectors on the performance of tandem OLEDs. The hole injection barriers are caused by the offset of the highest occupied molecular orbital (HOMO) energy levels between HTLs contained in the intermediate connector and the top electroluminescence (EL) unit. We also find that although charge generation can occur at the interfaces between the TMO and a wide variety of HTLs of different HOMO values, an increase in the hole injection barrier however limits the electroluminescence efficiency of the top EL units. In the case of large hole injection barriers, significant charge accumulation in the HTLs makes the intermediate connector lose its functionality gradually over operating time, and limits device stability.

2012-01-01

Objective To determine the prevalence of medical and nonmedical use of prescription opioids among high school seniors in the United States, and to assess substance use behaviors based on medical and nonmedical use of prescription opioids. Design Nationally representative samples of high school seniors (modal age 18) were surveyed during the spring of their senior year via self-administered questionnaires. Setting Data were collected in public and private high schools. Participants The sample consisted of 7,374 students from three independent cohorts (2007-09). Main Outcome Measures Self-reports of medical and nonmedical use of prescription opioids and other substance use. Results An estimated 17.6% of high school seniors reported lifetime medical use of prescription opioids, while 12.9% reported nonmedical use of prescription opioids. Gender differences in the medical and nonmedical use were minimal, while racial/ethnic differences were extensive. Over 37% of nonmedical users reported intranasal administration of prescription opioids. An estimated 80% of nonmedical users with an earlier history of medical use had obtained prescription opioids from a prescription they had previously. The odds of substance use behaviors were greater among individuals who reported any history of nonmedical use of prescription opioids relative to those who reported medical use only. Conclusions Nearly one in every four high school seniors in the United States has ever had some exposure to prescription opioids either medically or nonmedically. The quantity of prescription opioids and number of refills prescribed to adolescents should be carefully considered and closely monitored to reduce subsequent nonmedical use of leftover medication.

To assess mental health education in the undergraduate pharmacy curricula in the United Kingdom and gauge how well prepared graduates are to manage mental health patients. The authors conducted semi-structured telephone interviews with pharmacy educators and administered an electronic self-administered survey instrument to pharmacy graduates. The mental health conditions of depression, schizophrenia, bipolar disorder, and Parkinson disease were taught, in detail, by all schools, but more specialized areas of mental health (eg, personality disorder, autism) were generally not taught. Just 5 of 19 schools attempted to teach the broader social aspects of mental health. A third of the schools provided experiential learning opportunities. Graduates and recently registered pharmacists stated that undergraduate education had prepared them adequately with regard to knowledge on conditions and treatment options, but that they were not as well prepared to talk with mental health patients and deal with practical drug management-related issues. The mental health portion of the undergraduate pharmacy curricula in colleges and schools of pharmacy in the United Kingdom is largely theoretical, and pharmacy students have little exposure to mental health patients. Graduates identified an inability to effectively communicate with these patients and manage common drug management-related issues.

1995-01-01

Over the past 20 years the incorporation of implant dentistry into academia has been documented in some detail for North American dental schools but has not been pursued on an international level. In June of 1993, we surveyed 51 dental schools outside of the United States affiliated with the University of Pennsylvania School of Dental Medicine's Office of International Relations concerning their teaching involvement with implant dentistry. Results from the 44 (86 percent) responding schools suggest that implant dentistry is being incorporated into predoctoral curriculums. Industrialized countries were more inclined to provide implant education. Insufficient time and the thought that the predoctoral level was not the place for implant dentistry were cited as some of the reasons for not incorporating implant dentistry into the curriculum. Oral surgery, prosthodontics, and periodontics departments developed and administered the implant curriculum. Formats varied among schools with respect to allotted time, curricular placement, laboratory experience, and clinical participation. Didactic material most frequently presented included a historical overview, diagnosis and treatment planning, classification of dental implants, and surgical and prosthetic concepts. Clinical involvement varied from actual implant placement to observation of prosthodontic procedures. Results were categorized based on the TOEFL (Test of English as a Foreign Language) classification of countries in six regions.

Following that, school classroom displacement ventilation and its thermal stratification and indoor air quality indicated by the CO 2 concentration have been numerically modeled concerning the effects of delivering ventilation flow rate and supplying air temperature. Numerical results indicate that the promotion of mechanical ventilation rate can simultaneously boost the dilution of indoor air pollutants and the non-uniformity of indoor thermal and pollutant distributions. Subsequent energy performance analysis demonstrates that classroom energy demands for ventilation and cooling could be reduced with the promotion of heat recovery efficiency of the ventilation facility, and the energy conservation ratio of the air conditioning unit decreases with the increasing temperatures of supplying air. Fitting correlations of heat recovery ventilation and cooling energy conservation have been presented. - Highlights: • Low energy school buildings and classroom environment. • Heat recovery facility operating with an air conditioning unit. • Displacement ventilation influenced by the heat recovery efficiency. • Energy conservation of cooling and ventilation through heat recovery. • Enhancement of classroom environment with reduction of school building energy

Full Text Available Aims: To report our experiences using Ozurdex, a biodegradable implant, containing 0.7 mg of dexamethasone in the treatment of noninfectious intermediate uveitis. Settings and Design: Retrospective study design. Methods: We conducted a retrospective study of medical records of patients with noninfectious intermediate uveitis having either cystoid macular edema (CME or vitritis who were not responsive to standard treatment and subsequently received Ozurdex implant from March 2011 to April 2013. The outcomes measured were best-corrected visual acuity, central retinal thickness (CRT, and vitreous haze score. Statistical Analysis Used: Paired t-test was used to test the significance of difference between quantitative variables. A P < 0.05 is taken to denote significant relationship. Results: Twenty eyes of 15 patients with mean age of 39.8 years who received Ozurdex implant were included in the study. The mean baseline visual acuity improved from 0. 666 logarithm of the minimum angle of resolution (logMAR units to 0.479 logMAR units at 6 weeks after the implant. The mean CRT improved from 536.1 to 361.4 microns at 6 weeks postimplant both parameters were statistically significant. The ocular inflammation was controlled in almost all the patients. Cataract and raised intraocular pressure were documented complications. Conclusion: Ozurdex implant is a promising treatment option and efficient in controlling the inflammation and CME in cases of noninfectious intermediate uveitis not responding to standard treatment.

Little information is available regarding the influence of dialysis facility size or profit status on intermediate outcomes in chronic dialysis patients. We have combined data from the Health Care Financing Administration (HCFA) Core Indicators Project; the end-stage renal disease (ESRD) facility survey; and the HCFA On-Line Survey, Certification, and Reporting System to analyze trends in this area. For hemodialysis patients, larger facilities were more likely than smaller facilities to perform dialysis on patients who were younger than 65 years of age, black, or undergoing dialysis 2 years or more (P profit units (P reduction ratio, but not with hematocrit or serum albumin values. Facility profit status was not associated with these intermediate outcomes. For peritoneal dialysis patients, there were no significant differences in patient demographics based on facility size. More patients in nonprofit units had been undergoing dialysis 2 or more years than patients in for-profit units (P profit status.

Jaegers, P.J.; Sanchez, R.G.

1996-01-01

Criticality benchmark data for intermediate energy spectrum systems does not exist. These systems are dominated by scattering and fission events induced by neutrons with energies between 1 eV and 1 MeV. Nuclear data uncertainties have been reported for such systems which can not be resolved without benchmark critical experiments. Intermediate energy spectrum systems have been proposed for the geological disposition of surplus fissile materials. Without the proper benchmarking of the nuclear data in the intermediate energy spectrum, adequate criticality safety margins can not be guaranteed. The Zeus critical experiment now under construction will provide this necessary benchmark data

Mental Health Curricula at Schools of Pharmacy in the United Kingdom and Recent Graduates’ Readiness to Practice

Science.gov (United States)

Taylor, Denise; Branford, Dave

2013-01-01

Objective. To assess mental health education in the undergraduate pharmacy curricula in the United Kingdom and gauge how well prepared graduates are to manage mental health patients. Method. The authors conducted semi-structured telephone interviews with pharmacy educators and administered an electronic self-administered survey instrument to pharmacy graduates. Results. The mental health conditions of depression, schizophrenia, bipolar disorder, and Parkinson disease were taught, in detail, by all schools, but more specialized areas of mental health (eg, personality disorder, autism) were generally not taught. Just 5 of 19 schools attempted to teach the broader social aspects of mental health. A third of the schools provided experiential learning opportunities. Graduates and recently registered pharmacists stated that undergraduate education had prepared them adequately with regard to knowledge on conditions and treatment options, but that they were not as well prepared to talk with mental health patients and deal with practical drug management-related issues. Conclusion. The mental health portion of the undergraduate pharmacy curricula in colleges and schools of pharmacy in the United Kingdom is largely theoretical, and pharmacy students have little exposure to mental health patients. Graduates identified an inability to effectively communicate with these patients and manage common drug management-related issues. PMID:24052650

Schools are in a unique position to ensure that all students meet the current physical activity (PA) recommendations. This study aimed to examine 1st to 3rd grade elementary students' accelerometer measured school day PA in the United States (U.S.) and Finland. The sample consisted of 200 students (107 girls, 93 boys; ages 6 to 8) and their school day PA was monitored with hip-worn ActiGraph GT3X+ accelerometers across a 5-day school week and the thresholds 100 and 2296 count per minute were used to separate sedentary time, light PA, and moderate-to-vigorous PA (MVPA). On an average school day, students were engaged in MVPA for 20.0 min in the U.S. and 24.1 min in Finland. Students' school-day MVPA was 9 to 16 minutes higher during physical education (PE) days compared with non-PE days (U.S: 25.8 vs. 16.6 min/day; Finland: 36.3 vs. 20.1 min/day). Girls had less MVPA and more sedentary time compared with boys in both samples. This study highlights both the role of PE and other school day physical activities in meeting PA guidelines. Policy measures are needed to change the structure of the school day and enhance PA to ensure that students meet the PA recommendations.

2011-04-01

Full Text Available The development of civilization made crises an inseparable part of our lives. Crises manifest themselves in almost all social areas and organizations, including educational institutions. The goals of the article are to present a theoretical model of normal, deviant and antisocial behaviors, and discuss the psycho-social characteristics of emotionally disturbed adolescents situated in a residential special education school in the United States. The article also gives an analysis of their most prevalent behavioral crises, escalation stages, as well as nonviolent crisis prevention and intervention strategies. The methods that were used include scientific literature review, analysis of statistical information supplied from different government sources, review and analysis of student records, as well as the author’s analytical reflections in working with emotionally disturbed youngsters in residential special education schools in the United States.The results of the study indicate that scientists from different fields use different terminology to describe socially nonconforming behaviors. The author presents a theoretical model of normal, deviant and antisocial behavior that could enhance better understanding and identification of high risk situations and conduct leading to serious crises. The analysis of student records revealed that most of the adolescents situated in special education residential schools are diagnosed with a number of mental health problems. This suggests that the currently prevailing care and education paradigm in the special education residential schools should shift to a more comprehensive treatment paradigm. The article also discusses the pros and cons of nonviolent crisis intervention. It is the author’s opinion that all special education schools serving children with emotional disorders should adopt one of the nonviolent crisis intervention models and develop and implement crisis management policies, plans and procedures.

Intermediate care (i.e., step-down or progressive care) is an alternative to the intensive care unit (ICU) for patients with moderate severity of illness. The adoption and current use of intermediate care is unknown. To characterize trends in intermediate care use among U.S. hospitals. We examined 135 million acute care hospitalizations among elderly individuals (≥65 yr) enrolled in fee-for-service Medicare (U.S. federal health insurance program) from 1996 to 2010. We identified patients receiving intermediate care as those with intensive care or coronary care room and board charges labeled intermediate ICU. In 1996, a total of 960 of the 3,425 hospitals providing critical care billed for intermediate care (28%), and this increased to 1,643 of 2,783 hospitals (59%) in 2010 (P billed for intermediate care, but billing steadily increased to 22.8% by 2010 (P billed for ICU care and ward-only care declined. Patients billed for intermediate care had more acute organ failures diagnoses codes compared with general ward patients (22.4% vs. 15.8%). When compared with patients billed for ICU care, those billed for intermediate care had fewer organ failures (22.4% vs. 43.4%), less mechanical ventilation (0.9% vs. 16.7%), lower mean Medicare spending ($8,514 vs. $18,150), and lower 30-day mortality (5.6% vs. 16.5%) (P billing increased markedly between 1996 and 2010. These findings highlight the need to better define the value, specific practices, and effective use of intermediate care for patients and hospitals.

2008-10-01

In 2006, the American Optometric Association Community Health Center Committee surveyed schools/colleges of optometry in the United States and its territories to assess collaborations between community health centers and optometric institutions. The survey investigated the number and structure of affiliations that existed between Federally Qualified Health Centers and schools/colleges of optometry in the United States. The survey reached the schools through the American Optometric Association Faculty Relations Committee or personal contact (Inter-American University of Puerto Rico). The survey showed wide variation in affiliations of community health centers with optometry programs. Six schools had no affiliations, whereas the remaining 11 ranged from 1 to 14. Information relating to 37 community health centers was reported. Results showed that schools utilized community health centers for fourth-year students in 5 schools, and both third- and fourth-year students in the remaining 6 schools. Schools vary regarding how precepting is managed with either full-time faculty (64.9%) or adjunct faculty. Business models also vary between schools. Affiliations between school/colleges of optometry and community health centers differ considerably. Optometric affiliations with community health centers can result in increased access to eye care for underserved populations and increased clinical experience for optometry students and residents. Opportunities exist to establish additional affiliations. Educational benefits and costs associated with affiliations should be explored before entering into a collaborative model of eye care delivery.

Teacher conceptions in the area of Nature Sciences about the construction of interdisciplinarity in Polytechnic Intermediate Education: the contribution of faculty expertise to reality in two schools in Northern Rio Grande do Sul

Directory of Open Access Journals (Sweden)

Bruna Carminatti

2015-08-01

Full Text Available High School education in Rio Grande do Sul underwent reformulations with the proposal for Polytechnic Intermediate Education suggested by the State Education Office. Overall, this proposal arose from the demand for improvements in elementary education, where High School education is concerned, and was implemented along the years of 2012, 2013 and 2014. Among the desired improvements was the need to overcome content education through interdisciplinarity and an integrated curriculum. Taking such changes into consideration – which implied the creation of knowledge areas, curricular restructuring, changes to the means of evaluation and the planning and teaching methodology presumptions – this article aims to report the path and results from research that proposed to investigate the manner in which interdisciplinarity began being constructed by educators in the area of Nature Sciences from faculty expertise. The methodology employed was of ethnographic research, that allowed to gather a wealth of data and opinions from the individuals investigated, namely nine teachers from the Nature Sciences area that encompasses the subjects of chemistry, physics and biology, from two intermediate education public schools in Northern Rio Grande do Sul. Data interpretation was carried out under the perspective of Discursive Textual Analysis and allowed for the identification of both the hurdles that made interdisciplinary construction and action unfeasible, such as lack of time for planning, and possible alternatives to overcome such hurdles, among which faculty expertise. From the discussion of those results, it can be observed that the proposal for Polytechnic High School provided space for the construction of the interdisciplinary praxis as well as for reflecting on and awareness building of its need, making it feasible from theoretic-methodological (reoptions on the part of the faculty in the bias of their expertise as such.

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.

Newborns were eligible for inclusion if they were clinically stable and were able to receive care in those two modalities. A decision tree model was developed that incorporated baseline variables and costs into a hypothetical cohort of 1,000 newborns, according to the literature and expert opinions. Daily cost was BR$343.53 for the second stage of the Kangaroo Unit and BR$394.22 for the Intermediate Neonatal Care Unit. The total cost for the hypothetical cohort was BR$5,710,281.66 for the second and third stages of the Kangaroo Unit and R$7,119,865.61 for the Intermediate Neonatal Care Unit. The Intermediate Neonatal Care Unit cost 25% more than the Kangaroo Unit. The study can contribute to decision-making in health, in addition to providing support for studies related to economic evaluation in neonatal health.

Previous experience has shown that school-based taekwondo training in the United States (US) results in many beneficial effect sregarding school education and the physical health of the adolescent participants; of especial significance, the training plays an important role in terms of exercise value and school-life adaptation. To explore this overall effect, a self-administered questionnaire was distributed to 401 adolescents over the age of 10 years. The survey comprisesa total of 29 questions that consist of 17 exercise-value-related questions (general, moral, and status) and 12 questions that are related to school-life adaptation (adaptation to teachers, adaptation to academic activities, adaptation to rule compliance, and adaptation to school activities). The survey results show that taekwondo training affects school-life adaptation by helping to improve student morality and by bolstering the students compliance with school rules during their schooling. The exercise value of taekwondo training is considered a necessity for US adolescents due to the corresponding educational aspects; in particular, the training plays a very important role in the maintenance of amenable student-teacher and student-peer relationships. From the previously mentioned findings, and if taekwondo teachers train their students carefully with educational missions in mind, it is expected that taekwondo training will play a very important role in the cultivation of anappropriate education value among US adolescents.

Governance-Default Risk Relationship and the Demand for Intermediated and Non-Intermediated Debt

Directory of Open Access Journals (Sweden)

Husam Aldamen

2012-09-01

Full Text Available This paper explores the impact of corporate governance on the demand for intermediated debt (asset finance, bank debt, non-bank private debt and non-intermediated debt (public debt in the Australian debt market. Relative to other countries the Australian debt market is characterised by higher proportions of intermediated or private debt with a lower inherent level of information asymmetry in that private lenders have greater access to financial information (Gray, Koh & Tong 2009. Our firm level, cross-sectional evidence suggests that higher corporate governance impacts demand for debt via the mitigation of default risk. However, this relationship is not uniform across all debt types. Intermediated debt such as bank and asset finance debt are more responsive to changes in governance-default risk relationship than non-bank and non-intermediated debt. The implication is that a firm’s demand for different debt types will reflect its governance-default risk profile.

Two measures for computing the cost of intermediate projects--a ratio of cost to charges and relative value units--are highly flawed and can have serious financial implications for the hospitals that use them. Full-cost accounting, using the principles of activity-based costing, enables hospitals to measure their costs more accurately, both for competitive bidding purposes and to manage them more effectively.

Kennel, C.F.; Blandford, R.D.; Coppi, P.

1989-01-01

Recent numerical investigations have focused attention once more on the role of intermediate shocks in MHD. Four types of intermediate shock are identified using a graphical representation of the MHD Rankine-Hugoniot conditions. This same representation can be used to exhibit the close relationship of intermediate shocks to switch-on shocks and rotational discontinuities. The conditions under which intermediate discontinuities can be found are elucidated. The variations in velocity, pressure, entropy and magnetic-field jumps with upstream parameters in intermediate shocks are exhibited graphically. The evolutionary arguments traditionally advanced against intermediate shocks may fail because the equations of classical MHD are not strictly hyperbolic. (author)

Everett Jones, Sherry; Guy, Gery P

2017-05-01

Exposure to the sun's UV radiation is a leading cause of skin cancer. Positive attitudes and beliefs about sun safety behavior, which would make sun protective behavior more likely, could be promoted and supported by school policies and practices. To identify school characteristics associated with having adopted practices that promote sun safety. School-level data from the February 3 to July 23, 2014, School Health Policies and Practices Study's Healthy and Safe School Environment questionnaire were analyzed. The School Health Policies and Practices Study uses a 2-stage sampling design to select a nationally representative sample of schools. All public, state-administered, Catholic, and non-Catholic private schools with any of the grades from kindergarten through 12 were eligible for inclusion. All analyses were conducted using weighted data. Prevalence of sun safety practices. In a nationally representative sample of 828 US schools, representatives of 577 schools (69.7%) responded. Overall, sun safety practices were not common among schools. The most frequent practice was having teachers allow time for students to apply sunscreen at school (47.6%; 95% CI, 42.4%-52.9%). Few schools made sunscreen available for students to use (13.3%; 95% CI, 10.2%-17.0%), almost always or always scheduled outdoor activities to avoid times when the sun was at peak intensity (15.0%; 95% CI, 11.4%-19.6%), or asked parents to ensure that students applied sunscreen before school (16.4%; 95% CI, 12.9%-20.6%). High schools were less likely than elementary schools and middle schools to adopt several practices: for instance, 37.5% of high schools (95% CI, 29.7%-46.0%), 51.6% of middle schools (95% CI, 43.3%-59.7%), and 49.5% of elementary schools (95% CI, 42.0%-57.0%) had teachers allow time for students to apply sunscreen at school, and 11.8% of high schools (95% CI, 7.7%-17.5%), 18.2% of middle schools (95% CI, 13.3%-24.4%), and 14.7% of elementary schools (95% CI, 9.6%-21.8%) almost

Fletcher, John L; Cancio, Leopoldo C; Sinha, Indranil; Leung, Kai P; Renz, Evan M; Chan, Rodney K

2015-12-01

Cutaneous allograft is commonly used in the early coverage of excised burns when autograft is unavailable. However, allograft is also applied in intermediate-extent burns (25-50%), during cases in which it is possible to autograft. In this population, there is a paucity of data on the indications for allograft use. This study explores the indications for allograft usage in moderate size burns. Under an IRB-approved protocol, patients admitted to our burn unit between March 2003 and December 2010 were identified through a review of the burn registry. Data on allograft use, total burn surface area, operation performed, operative intent, number of operations, intensive care unit length of stay, and overall length of stay were collected and analyzed. Data are presented as means±standard deviations, except where noted. In the study period, 146 patients received allograft during their acute hospitalization. Twenty-five percent of allograft recipients sustained intermediate-extent burns. Patients with intermediate-extent burns received allograft later in their hospitalization than those with large-extent (50-75% TBSA) burns (6.8 days vs. 3.4 days, p=0.01). Allografted patients with intermediate-extent burns underwent more operations (10.8 vs. 6.1, p=0.002) and had longer hospitalizations (78.3 days vs. 40.9 days, ppatients, when controlled for TBSA. Clinical rationale for placement of allograft in this population included autograft failure, uncertain depth of excision, lack of autograft donor site, and wound complexity. When uncertain depth of excision was the indication, allograft was universally applied onto the face. In half of allografted intermediate-extent burn patients the inability to identify a viable recipient bed was the ultimate reason for allograft use. Unlike large body surface area burns, allograft skin use in intermediate-extent injury occurs later in the hospitalization and is driven by the inability to determine wound bed suitability for autograft

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.

Sports-related injuries among high school athletes--United States, 2005-06 school year.

Science.gov (United States)

2006-09-29

Participation in high school sports helps promote a physically active lifestyle. High school sports participation has grown from an estimated 4 million participants during the 1971-72 school year to an estimated 7.2 million in 2005-06. However, despite the documented health benefits of increased physical activity (e.g., weight management, improved self-esteem, and increased strength, endurance, and flexibility), those who participate in athletics are at risk for sports-related injuries. High school athletes account for an estimated 2 million injuries, 500,000 doctor visits, and 30,000 hospitalizations annually. To date, the study of these injuries has been limited by inabilities to calculate injury rates, compare results among groups, and generalize findings from small, nonrepresentative samples. During the 2005-06 school year, researchers at a children's hospital in Ohio used an Internet-based data-collection tool to pilot an injury surveillance system among athletes from a representative national sample of U.S. high schools. This report summarizes the findings of that study, which indicated that participation in high school sports resulted in an estimated 1.4 million injuries at a rate of 2.4 injuries per 1,000 athlete exposures (i.e., practices or competitions). Surveillance of exposure-based injury rates in a nationally representative sample of high school athletes and analysis of injury patterns can help guide activities aimed at reducing these injuries.

Many people with low back pain (LBP) become frequent users of healthcare services in their attempt to find treatments that minimise the severity of their symptoms. Back School consists of a therapeutic programme given to groups of people that includes both education and exercise. However, the content of Back School has changed over time and appears to vary widely today. This review is an update of a Cochrane review of randomised controlled trials (RCTs) evaluating the effectiveness of Back School. We split the Cochrane review into two reviews, one focusing on acute and subacute LBP, and one on chronic LBP. The objective of this systematic review was to determine the effect of Back School on pain and disability for adults with chronic non-specific LBP; we included adverse events as a secondary outcome. In trials that solely recruited workers, we also examined the effect on work status. We searched for trials in the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, CINAHL, two other databases and two trials registers to 15 November 2016. We also searched the reference lists of eligible papers and consulted experts in the field of LBP management to identify any potentially relevant studies we may have missed. We placed no limitations on language or date of publication. We included only RCTs and quasi-RCTs evaluating pain, disability, and/or work status as outcomes. The primary outcomes for this update were pain and disability, and the secondary outcomes were work status and adverse events. Two review authors independently performed the 'Risk of bias' assessment of the included studies using the 'Risk of bias' assessment tool recommended by The Cochrane Collaboration. We summarised the results for the short-, intermediate-, and long-term follow-ups. We evaluated the overall quality of evidence using the GRADE approach. For the outcome pain, at short-term follow-up, we found very low-quality evidence that Back School is more effective than no

1979-07-01

We have combined microbeam and flow techniques with computer subtraction methods to obtain the resonance Raman spectrum of the short lived batho-intermediate (bK(590)) of bacteriorhodopsin. Comparison of the spectra obtained in (1)H(2)O and (2)H(2)O, as well as the fact that the bK(590) intermediate shows large optical red shifts, suggests that the Schiff base linkage of this intermediate is protonated. The fingerprint region of the spectrum of bK(590), sensitive to the isomeric configuration of the retinal chromophore, does not resemble the corresponding region of the parent bR(570) form. The resonance Raman spectrum of bK(590) as well as the spectra of all of the other main intermediates in the photoreaction cycle of bacteriorhodopsin are discussed and compared with resonance Raman spectra of published model compounds.

Conceptions of Adolescence: Implications for Differences in Engagement in School Over Early Adolescence in the United States and China.

2016-07-01

American youth are more prone to storm and stress during adolescence than are Chinese youth (e.g., American youth's engagement in school declines more). However, it is unclear why. This research examined differences in conceptions of adolescence in the United States and China. Using both open- and closed-ended measures, youth (N = 397; 50 % female; mean age = 13.19 years) reported on their views of teens. American (vs. Chinese) youth were more likely to see adolescence as a time of decreased family responsibility along with increased individuation from parents, school disengagement, and peer orientation. Conceptions of adolescence as a time of dampened family responsibility and heightened school disengagement contributed to American (vs. Chinese) youth being less engaged in school over the seventh and eighth grades. The findings suggest that culture shapes ideas about adolescence, which contribute to differences in American and Chinese youth's engagement in school over this phase.

Role of Intermediate Filaments in Vesicular Traffic

Directory of Open Access Journals (Sweden)

Azzurra Margiotta

2016-04-01

Full Text Available Intermediate filaments are an important component of the cellular cytoskeleton. The first established role attributed to intermediate filaments was the mechanical support to cells. However, it is now clear that intermediate filaments have many different roles affecting a variety of other biological functions, such as the organization of microtubules and microfilaments, the regulation of nuclear structure and activity, the control of cell cycle and the regulation of signal transduction pathways. Furthermore, a number of intermediate filament proteins have been involved in the acquisition of tumorigenic properties. Over the last years, a strong involvement of intermediate filament proteins in the regulation of several aspects of intracellular trafficking has strongly emerged. Here, we review the functions of intermediate filaments proteins focusing mainly on the recent knowledge gained from the discovery that intermediate filaments associate with key proteins of the vesicular membrane transport machinery. In particular, we analyze the current understanding of the contribution of intermediate filaments to the endocytic pathway.

Tobacco use and addiction most often begin during youth and young adulthood. Youth use of tobacco in any form is unsafe. To determine the prevalence and trends of current (past 30-day) use of nine tobacco products (cigarettes, cigars, smokeless tobacco, e-cigarettes, hookahs, tobacco pipes, snus, dissolvable tobacco, and bidis) among U.S. middle (grades 6-8) and high school (grades 9-12) students, CDC and the Food and Drug Administration (FDA) analyzed data from the 2011-2014 National Youth Tobacco Surveys (NYTS). In 2014, e-cigarettes were the most commonly used tobacco product among middle (3.9%) and high (13.4%) school students. Between 2011 and 2014, statistically significant increases were observed among these students for current use of both e-cigarettes and hookahs (pstudents continue to be exposed to harmful tobacco product constituents, including nicotine. Nicotine exposure during adolescence, a critical window for brain development, might have lasting adverse consequences for brain development, causes addiction, and might lead to sustained tobacco use. For this reason, comprehensive and sustained strategies are needed to prevent and reduce the use of all tobacco products among youths in the United States.

Health profession schools use interviews during the admissions process to identify certain non-cognitive skills that are needed for success in diverse, inter-professional settings. This study aimed to assess the use of interviews during the student admissions process across health disciplines at schools in the United States of America in 2014. The type and frequency of non-cognitive skills assessed were also evaluated. Descriptive methods were used to analyze a sample of interview rubrics collected as part of a national survey on admissions in the health professions, which surveyed 228 schools of medicine, dentistry, pharmacy, nursing, and public health. Of the 228 schools, 130 used interviews. The most desirable non-cognitive skills from 34 schools were identified as follows: communication skills (30), motivation (22), readiness for the profession (17), service (12), and problem-solving (12). Ten schools reported using the multiple mini-interview format, which may indicate potential for expanding this practice. Disparities in the use of interviewing across health professions should be verified to help schools adopt interviews during student admissions processes.

Helicobacter Pylori: Prevalence and relationship with abdominal pain in school children in makkah city, western Saudi Arabia

International Nuclear Information System (INIS)

Telmesani, Abdulwahab MA

2009-01-01

The published data on Helicobacter pylori ( H. pylori ) prevalence and its relationship with abdominal pain in Saudi Arabia is scarce. This study was carried out to determine the prevalence of H. pylori and its relationship with chronic recurrent abdominal pain (RAP) among school students in Makkah City, Saudi Arabia. Three hundred and fourteen school students, 103 at the intermediate level (grades 7-9) aged 12-15 years and 211 at the secondary level (grades 10-12) aged 15-18 years were tested for H. pylori. Urea breath test (UBT) was used for this purpose. Children with chronic RAP were identified as per the Apley criteria. Overall, the UBT was positive in 86/314 (27.4%) students. It was positive in 45/103 (43.7%) intermediate school students and 41/211 (19.4%) secondary students. Out of the 55 students with chronic RAP, 40 (73%) were positive for H. pylori . Further, 62.9% and 82.1% were positive among the intermediate and secondary school students with RAP, respectively. The overall and specific odds ratios of RAP were 12.35 [95% confidence interval (C.I.) 6.30-24.22] and 10.40 (95% C.I. 1.75-11.73) for the intermediate school students and 22.69 (95% C.I. 7.99-64.44) for the secondary school students. The prevalence of H. pylori among the school children in Makkah, Saudi Arabia, is relatively low compared with developing countries. The prevalence was found to be higher among the younger age group. Further, there was a significant relation between H. pylori infection and RAP among the school students. (author)

A 15-year study found that Amish schools have increased, numbering 1,139 in 2000. Where public school funding is on a per-pupil basis, these schools may have a negative effect on rural school district financing. However, an Amish community may increase local farm-related trade and tourism, thereby increasing taxable property and public school…

The present status of geography education in boys' intermediate schools of Riyadh, Saudi Arabia

Science.gov (United States)

Al-Gahtany, Abdulrahman Mohammed

The purpose of this study was to describe the present status of geography education in boys' intermediate schools in Riyadh, Saudi Arabia as perceived by geography teachers and supervisors; that is, to investigate the objectives, content, methods of teaching, tools and resources that are available and used in classrooms, evaluation techniques, and problems encountered in the teaching of geography. To collect data from this representative sample population, a questionnaire was developed by the researcher specifically for this study. Questionnaire data was collected from 19 social studies supervisors and 213 geography teachers. Percentages, frequencies, means, and standard deviations were computed for each questionnaire item. Chi Square tests were applied to determine if any significant differences could be identified between the observed and expected responses of supervisors and teachers. Major findings of the study indicated that both supervisors and teachers tend to strongly support the identified geography objectives. Most teachers and supervisors also indicated that the current geography curriculum contains enough information about Saudi Arabia, the Arabic world, and the Islamic world. In addition, the also indicated that geography content promotes a sense of patriotism and cultural pride. Responses indicated that educators see deficiencies in the content: it does not focus sufficiently on current events nor on developing student skills such as research and technical skills like drawing maps. Lecture and discussion are the most commonly used strategies in the teaching of geography. Field trips, role-playing, scientific competitions, scientific games, solving problems, and individual learning are less commonly used. Teaching tools most commonly used are wall maps and earth globes, whereas the use of geographical transparencies, models, and instruments is not common. Most of the teachers do lot use computers in their teaching. Evaluation techniques depend

Electron-atom scattering at intermediate energies

International Nuclear Information System (INIS)

Kingston, A.E.; Walters, H.R.J.

1982-01-01

The problems of intermediate energy scattering are approached from the low and high energy ends. At low intermediate energies difficulties associated with the use of pseudostates and correlation terms are discussed, special consideration being given to nonphysical pseudoresonances. Perturbation methods appropriate to high intermediate energies are described and attempts to extend these high energy approximations down to low intermediate energies are studied. It is shown how the importance of electron exchange effects develops with decreasing energy. The problem of assessing the 'effective completeness' of pseudostate sets at intermediate energies is mentioned and an instructive analysis of a 2p pseudostate approximation to elastic e - -H scattering is given. It is suggested that at low energies the Pauli Exclusion Principle can act to hide short range defects in pseudostate approximations. (author)

Higher order antibunching in intermediate states

International Nuclear Information System (INIS)

Verma, Amit; Sharma, Navneet K.; Pathak, Anirban

2008-01-01

Since the introduction of binomial state as an intermediate state, different intermediate states have been proposed. Different nonclassical effects have also been reported in these intermediate states. But till now higher order antibunching is predicted in only one type of intermediate state, which is known as shadowed negative binomial state. Recently we have shown that the higher order antibunching is not a rare phenomenon [P. Gupta, P. Pandey, A. Pathak, J. Phys. B 39 (2006) 1137]. To establish our earlier claim further, here we have shown that the higher order antibunching can be seen in different intermediate states, such as binomial state, reciprocal binomial state, hypergeometric state, generalized binomial state, negative binomial state and photon added coherent state. We have studied the possibility of observing the higher order subpoissonian photon statistics in different limits of intermediate states. The effects of different control parameters on the depth of non classicality have also been studied in this connection and it has been shown that the depth of nonclassicality can be tuned by controlling various physical parameters

Intermediate uveitis is a form of intraocular inflammation in which the vitreous body is the major site of inflammation. Intermediate uveitis is primarily treated medicinally and systemic corticosteroids are the mainstay of therapy. When recurrence of uveitis or side effects occur during corticosteroid therapy an immunosuppressive treatment is required. Cyclosporine A is the only immunosuppressive agent that is approved for therapy of uveitis in Germany; however, other immunosuppressive drugs have also been shown to be effective and well-tolerated in patients with intermediate uveitis. In severe therapy-refractory cases when conventional immunosuppressive therapy has failed, biologics can be used. In patients with unilateral uveitis or when the systemic therapy is contraindicated because of side effects, an intravitreal steroid treatment can be carried out. In certain cases a vitrectomy may be used.

Optimal design of the cable metro with unified intermediate supports

Lagerev A.V.

slope of the surface relief also has discrete-step type. The transition to a larger height unified intermediate supports determines the need for installation of supports with a large pitch. Its value then begins to decrease monotonically with further increase of the angle of the longitudinal slope of the surface relief until it needs to transition to the new size of supports. Synchronous change in the optimal values of the height and step of the installation of intermediate supports, depending on the angle of the longitudinal slope of the sur-face relief leads to the fact that the optimal cost characteristics of the cable metro lines are smooth functions. It has an extreme character with a minimum at angles of inclination of the surface elevation ~5 degrees, which is associated with the form of sagging of the load-bearing ropes. Unification of intermediate supports has little effect on the optimal cost characteristics of the cable metro lines. Even for a sufficiently large step of the unification the largest difference in op-timal value is almost insignificant: it lies in the range of 2...3%, increasing with increasing the angle of the longitudinal slope of the surface relief and unit cost of the intermediate support. Unification of intermediate supports according to the height and their step practically does not affect the optimal value for horizontal tension on the load-bearing ropes. It determined mainly by the angle of the longitudinal slope of the surface relief. Deviation of horizontal tension on the load-bearing ropes for the nonstandard supports and the unified supports within the range of angles of inclination of the terrain surface 0...60 degrees is not more than 0.5 to 0.8 %.

International students in United States’ medical schools: does the medical community know they exist?

Directory of Open Access Journals (Sweden)

Jashodeep Datta

2012-06-01

Full Text Available Background: Matriculation of international students to United States’ (US medical schools has not mirrored the remarkable influx of these students to other US institutions of higher education. Methods: While these students’ numbers are on the rise, the visibility for their unique issues remains largely ignored in the medical literature. Results: These students are disadvantaged in the medical school admissions process due to financial and immigration-related concerns, and academic standards for admittance also continue to be significantly higher compared with their US-citizen peers. Furthermore, it is simply beyond the mission of many medical schools – both public and private – to support international students’ education, especially since federal, state-allocated or institutional funds are limited and these institutions have a commitment to fulfill the healthcare education needs of qualified domestic candidates. In spite of these obstacles, a select group of international students do gain admission to US medical schools and, upon graduation, are credentialed equally as their US-citizen counterparts by the Accreditation Council for Graduate Medical Education (ACGME. However, owing to their foreign citizenship, these students have visa requirements for post-graduate training that may adversely impact their candidacy for residency placement. Conclusion: By raising such issues, this article aims to increase the awareness of considerations pertinent to this unique population of medical students. The argument is also made to support continued recruitment of international students to US medical schools in spite of these impediments. In our experience, these students are not only qualified to tackle the rigors of a US medical education, but also enrich the cultural diversity of the medical student body. Moreover, these graduates could effectively complement the efforts to augment US physician workforce diversity while contributing to

Although recent studies indicate that rates of childhood obesity and severe obesity may be declining, few studies have reported prevalence trends in early childhood or differences in trends across sociodemographic groups. The primary aim of this study was to report trends in prevalence of early childhood obesity and severe obesity 2007 through 2014 in a diverse, metropolitan school district in the southwestern United States and determine whether these trends vary by race/ethnicity, socioeconomic status, and disability status. We analyzed height, weight and demographic data from 43,113 kindergarteners enrolled in a large, urban school district in the southwestern United States for 7 school years. Adjusted odds of obesity and severe obesity were calculated to assess changes in prevalence for non-Hispanic white, Hispanic, and American Indian students; free or reduced-price lunch participants and nonparticipants; and students with and without disabilities. To test for differences in obesity trends, interaction terms were added to the logistic regressions between school year and sex, race/ethnicity, free or reduced-price lunch participation, and disability status. The adjusted prevalence of both obesity (from 13.1% in 2007-2008 to 12.0% in 2013-20014) and severe obesity (from 2.4% in 2007-2008 to 1.2% in 2013-2014) declined overall. We found no significant interactions between the adjusted prevalence of obesity over time and any of the sociodemographic subgroups. Obesity prevalence declined more among American Indian students than among Hispanic or non-Hispanic white students. In this district, from 2007 through 2014, severe obesity decreased and obesity did not increase, overall and across all sociodemographic subpopulations for kindergarten students.

Gil, Joseph A; Park, Sarah H; Daniels, Alan H

2015-11-01

Over the course of the last generation, the cost of medical school attendance and medical student debt has increased drastically. Medical student debt has been reported as high as $350,000, and the Association of American Medical Colleges (AAMC) reports that medical school tuition continues to increase annually. The increasing cost of medical education and associated financial burden is now beginning to deter potential applicants from pursuing a career in medicine. In this study we aimed to assess medical school tuition across the US. We hypothesized that the cost of medical school attendance is variable across all regions of the US, and as a result, the financial burden on medical students is inconsistent. All 123 allopathic medical schools accredited by the AAMC were assessed in this investigation. In-state and out-of-state tuitions for the year 2016 were obtained from U.S. News and World Report. Additionally, medical school size was collected. Regions were defined according to the US Census Bureau definition, with the US being divided into 4 regions: Northeast, Midwest, South, and West. There was no difference in average medical school size among the 4 regions (P > .05). Average in-state tuition was $38,291.56 ± $9801.38 (95% confidence interval [CI], $34,658.07-$41,513.46) in the Midwest, $45,923.04 ± $9178.87 (95% CI, $42,566.28-$49,216.78) in the Northeast, $32,287.78 ± $12,277.53 (95% CI, $28,581.90-$35,378.68) in the South, and $37,745.40 ± $11,414.37 (95% CI, $30,063.28-$40,458.99) in the West. In-state tuition in the South was significantly lower than in the Northeast, West, and Midwest (P tuition in the Northeast was significantly higher than in the South, West, and Midwest (P tuition is $54,104.04 ± $8227.65 (95% CI, $51,207.6-$57,000.39) in the Midwest, $53,180.10 ± $3963.71 (95% CI, $51,761.71-$54,598.50) in the Northeast, $48,191.86 ± $12,578.13 (95% CI, $44,595.84-$51,787.89) in the South, and $52,920.47 ± $7400.83 (95% CI, $49

Effect of Intermediate Hosts on Emerging Zoonoses.

Cui, Jing-An; Chen, Fangyuan; Fan, Shengjie

2017-08-01

Most emerging zoonotic pathogens originate from animals. They can directly infect humans through natural reservoirs or indirectly through intermediate hosts. As a bridge, an intermediate host plays different roles in the transmission of zoonotic pathogens. In this study, we present three types of pathogen transmission to evaluate the effect of intermediate hosts on emerging zoonotic diseases in human epidemics. These types are identified as follows: TYPE 1, pathogen transmission without an intermediate host for comparison; TYPE 2, pathogen transmission with an intermediate host as an amplifier; and TYPE 3, pathogen transmission with an intermediate host as a vessel for genetic variation. In addition, we established three mathematical models to elucidate the mechanisms underlying zoonotic disease transmission according to these three types. Stability analysis indicated that the existence of intermediate hosts increased the difficulty of controlling zoonotic diseases because of more difficult conditions to satisfy for the disease to die out. The human epidemic would die out under the following conditions: TYPE 1: [Formula: see text] and [Formula: see text]; TYPE 2: [Formula: see text], [Formula: see text], and [Formula: see text]; and TYPE 3: [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text] Simulation with similar parameters demonstrated that intermediate hosts could change the peak time and number of infected humans during a human epidemic; intermediate hosts also exerted different effects on controlling the prevalence of a human epidemic with natural reservoirs in different periods, which is important in addressing problems in public health. Monitoring and controlling the number of natural reservoirs and intermediate hosts at the right time would successfully manage and prevent the prevalence of emerging zoonoses in humans.

Interaction between Financial Intermediation Efficiency and Economic Growth

Directory of Open Access Journals (Sweden)

Milka Grbic

2016-12-01

Full Text Available Financial intermediaries have the key role in making a connection between savings and investments. Given the fact that an efficient transfer of savings into investments is made more difficult by transaction and information costs, financial intermediaries are specialized in minimizing the said costs per unit of invested capital. They are also trained to identify productive and innovative investment endeavors which contribute to the growth of real output. Real output growth is the basis for increasing the financial potential, which creates the basis for the development of financial intermediaries. In connection with that, apart from the analysis of the relevant factors making the process of the mobilization and transfer of savings more difficult, the theoretical models that put an emphasis on the relationship between the efficiency of financial intermediation and economic growth are discussed in the paper. The research results are indicative of the fact that the improvement in financial intermediaries’ business doing enables faster economic growth. Simultaneously, the growth of the economic activity increases the scope of the business operations conducted by financial intermediaries. Thanks to the effects of the economies of scale that contribute to a reduction in transaction and information costs, the efficiency of financial intermediations grows.

An estimated 1.1 million high school and 75,000 college athletes participate in tackle football annually in the United States. Football is a collision sport; traumatic injuries are frequent (1,2), and can be fatal (3). This report updates the incidence and characteristics of deaths caused by traumatic brain injury and spinal cord injury (4) in high school and college football and presents illustrative case descriptions. Information was analyzed from the National Center for Catastrophic Sport Injury Research (NCCSIR). During 2005-2014, a total of 28 deaths (2.8 deaths per year) from traumatic brain and spinal cord injuries occurred among high school (24 deaths) and college football players (four deaths) combined. Most deaths occurred during competitions and resulted from tackling or being tackled. All four of the college deaths and 14 (58%) of the 24 high school deaths occurred during the last 5 years (2010-2014) of the 10-year study period. These findings support the need for continued surveillance and safety efforts (particularly during competition) to ensure proper tackling techniques, emergency planning for severe injuries, availability of medical care onsite during competitions, and assessment that it is safe to return to play following a concussion.

Full Text Available Evidence of the impact of water, sanitation, and hygiene (WASH in schools (WinS interventions on pupil absence and health is mixed. Few WinS evaluations rigorously report on output and outcome measures that allow for comparisons of effectiveness between interventions to be made, or for an understanding of why programs succeed. The Water, Sanitation, and Hygiene for Health and Education in Laotian Primary Schools (WASH HELPS study was a randomized controlled trial designed to measure the impact of the United Nations Children’s Fund (UNICEF Laos WinS project on child health and education. We also measured the sustainability of intervention outputs and outcomes, and analyzed the effectiveness of group hygiene activities on behavior change and habit formation. Here, we present the design and intermediate results from this study. We found the WinS project improved the WASH environment in intervention schools; 87.8% of schools received the intervention per design. School-level adherence to outputs was lower; on average, schools met 61.4% of adherence-related criteria. The WinS project produced positive changes in pupils’ school WASH behaviors, specifically increasing toilet use and daily group handwashing. Daily group hygiene activities are effective strategies to improve school WASH behaviors, but a complementary strategy needs to be concurrently promoted for effective and sustained individual handwashing practice at critical times.

Intermediate size LWR plant study for process heat plus power. Volume 1. Executive summary

Head, M.A.

1977-01-01

The appropriateness of intermediate sized LWRs is evaluated for application to the process industry and for cogeneration of electric power and process steam. This brief study is directed toward determination of whether such plants show enough promise to warrant more detailed investigation. In light of higher fossil fuel costs, the study shows that intermediate sized, standardized power plants potentially are economically competitive for such industrial applications. A representative intermediate sized operating plant of the BWR/4 design class, the Swiss Muhleberg unit (1000 MWt) has been examined with respect to design, licensability, capacity factor and cost. It has operated at high capacity factor (approximately 75 percent) since turnover 11/72. Its cost when escalated from 1969 to 1976 ($620/kWe) appears competitive. Cost adjustments ($100-$250/kWe) included at this stage for compliance with current licensing and mandatory design requirements are only a preliminary estimate. Further study is recommended to confirm necessary regulatory upgrades for this BWR/4 nuclear plant and to explore specific cost economies through replication leading to a program for construction of a demonstration plant

Lithium hydride (LiH) is employed as a novel n-dopant in the intermediate connector for tandem organic light-emitting diodes (OLEDs) because of its easy coevaporation with other electron transporting materials. The tandem OLEDs with two and three electroluminescent (EL) units connected by a combination of LiH doped 8-hydroxyquinoline aluminum (Alq3) and 1,4,5,8,9,11-hexaazatriphenylene-hexacarbonitrile (HAT-CN) demonstrate approximately 2-fold and 3-fold enhancement in current efficiency, respectively. In addition, no extra voltage drop across the intermediate connector is observed. Particularly, the lifetime (T75%) in the tandem OLED with two and three EL units is substantially improved by 3.8 times and 7.4 times, respectively. The doping effect of LiH into Alq3, the charge injection, and transport characteristics of LiH-doped Alq3 are further investigated by ultraviolet photoelectron spectroscopy (UPS) and X-ray photoemission spectroscopy (XPS).

Governance Based on Cost Analysis (Unit Cost Analysis for Vocational Schools

Chandra Situmeang

2018-02-01

Full Text Available This study aims to calculate unit cost to produce one middle-level vocational school graduate (in Indonesian terms known as "Sekolah Menengah Kejuruan” abbreviated as SMK. The calculation is required because operational grant funds (in Indonesian terms known as antuan Operasional Sekolah abbreviated as BOS are distributed so far to the same extent in all areas of Indonesia and for all majors. This is most likely less than optimal because in fact there are very basic characteristics differences including; Economic capacity of each region, the cost standard for each region, and the type of department in the school. Based on this, the researcher assumed that cost analysis should be done by considering these things as a basis to provide BOS funds tailored to specific characteristics. The data to be analyzed in this research is North Sumatra province data. This research is conducted in two stages, which in this report only completed the first phase which is a survey in North Sumatra region. Stages of survey to obtain data which then analyzed with related data such as community income, learning outcomes through the value of national examinations, tuition fee, and conditions of learning facilities. The research is funded by the ministries of research, technology and higher education through competing grant schemes for fiscal year 2017 and 2018. The result of correlation analysis between the variables shows that there is a strong relationship between the average income with average tuition paid by the community and between average tuition paid by the community with Quality Level of Education Facilities. The result of correlation analysis also shows a moderate relationship between the average tuition with learning outcomes measured through average national exam and relationship between quality level of education facilities with average national exam. While the relationship between average income with average national exam does not have a strong

It was suggested to conduct the investigation into particles in 1976 by cline, Rubbia and Makintair using proton-antiproton beams. Major difficulties of the experiment are related to the necessity of formation of sufficient amount of antiparticles and the method of antiproton beam ''cooling'' for the purpose of reduction of its random movements. The stochastic method was suggested by van der Meer in 1968 as one of possible cooling methods. Several large detectors were designed for searching intermediate vector bosons

To identify the manner in which colleges and schools of pharmacy in the United States and Puerto Rico assess full-time faculty preceptors. Directors of pharmacy practice (or equivalent title) were invited to complete an online, self-administered questionnaire. Seventy of the 75 respondents (93.3%) confirmed that their college or school assessed full-time pharmacy faculty members based on activities related to precepting students at a practice site. The most commonly reported assessment components were summative student evaluations (98.5%), type of professional service provided (92.3%), scholarly accomplishments (86.2%), and community service (72.3%). Approximately 42% of respondents indicated that a letter of evaluation provided by a site-based supervisor was included in their assessment process. Some colleges and schools also conducted onsite assessment of faculty members. Most colleges and schools of pharmacy assess full-time faculty-member preceptors via summative student assessments, although other strategies are used. Given the important role of preceptors in ensuring students are prepared for pharmacy practice, colleges and schools of pharmacy should review their assessment strategies for full-time faculty preceptors, keeping in mind the methodologies used by other institutions.

Investigations using intermediate end points as cancer surrogates are quicker, smaller, and less expensive than studies that use malignancy as the end point. We present a strategy for determining whether a given biomarker is a valid intermediate end point between an exposure and incidence of cancer. Candidate intermediate end points may be selected from case series, ecologic studies, and animal experiments. Prospective cohort and sometimes case-control studies may be used to quantify the intermediate end point-cancer association. The most appropriate measure of this association is the attributable proportion. The intermediate end point is a valid cancer surrogate if the attributable proportion is close to 1.0, but not if it is close to 0. Usually, the attributable proportion is close to neither 1.0 nor 0; in this case, valid surrogacy requires that the intermediate end point mediate an established exposure-cancer relation. This would in turn imply that the exposure effect would vanish if adjusted for the intermediate end point. We discuss the relative advantages of intervention and observational studies for the validation of intermediate end points. This validation strategy also may be applied to intermediate end points for adverse reproductive outcomes and chronic diseases other than cancer.

Studies have shown links between educational outcomes such as letter grades, test scores, or other measures of academic achievement, and health-related behaviors (1-4). However, as reported in a 2013 systematic review, many of these studies have used samples that are not nationally representative, and quite a few studies are now at least 2 decades old (1). To update the relevant data, CDC analyzed results from the 2015 national Youth Risk Behavior Survey (YRBS), a biennial, cross-sectional, school-based survey measuring health-related behaviors among U.S. students in grades 9-12. Analyses assessed relationships between academic achievement (i.e., self-reported letter grades in school) and 30 health-related behaviors (categorized as dietary behaviors, physical activity, sedentary behaviors, substance use, sexual risk behaviors, violence-related behaviors, and suicide-related behaviors) that contribute to leading causes of morbidity and mortality among adolescents in the United States (5). Logistic regression models controlling for sex, race/ethnicity, and grade in school found that students who earned mostly A's, mostly B's, or mostly C's had statistically significantly higher prevalence estimates for most protective health-related behaviors and significantly lower prevalence estimates for most health-related risk behaviors than did students with mostly D's/F's. These findings highlight the link between health-related behaviors and education outcomes, suggesting that education and public health professionals can find their respective education and health improvement goals to be mutually beneficial. Education and public health professionals might benefit from collaborating to achieve both improved education and health outcomes for youths.

Simplifying biochemical models with intermediate species

DEFF Research Database (Denmark)

Feliu, Elisenda; Wiuf, Carsten

2013-01-01

techniques, we study systematically the effects of intermediate, or transient, species in biochemical systems and provide a simple, yet rigorous mathematical classification of all models obtained from a core model by including intermediates. Main examples include enzymatic and post-translational modification...... systems, where intermediates often are considered insignificant and neglected in a model, or they are not included because we are unaware of their existence. All possible models obtained from the core model are classified into a finite number of classes. Each class is defined by a mathematically simple...... canonical model that characterizes crucial dynamical properties, such as mono- and multistationarity and stability of steady states, of all models in the class. We show that if the core model does not have conservation laws, then the introduction of intermediates does not change the steady...

Origin of the complex crystal structures of elements at intermediate pressure

International Nuclear Information System (INIS)

Ackland, G J; Macleod, I R

2004-01-01

We present a unifying theory for the observed complex structures of sp-bonded elements under pressure on the basis of nearly free electron picture. In the intermediate pressure regime, the dominant contribution to crystal structure arises from Fermi-surface Brillouin zone interactions-structures which allow this are favoured. This simple theory explains the observed crystal structures, transport properties and the evolution of internal and unit cell parameters with pressure and appears to hold for elements in groups I-VI. We illustrate it with experimental data for these elements and ab initio calculations for Li

The 5-year period of 2005-2009 saw more exertional heat stroke-related deaths in organized sports than any other 5-year period in the past 35 years. The risk of exertional heat stroke appears highest in football, particularly during the preseason. To estimate the incidence of exertional heat stroke events and assess the utilization of exertional heat stroke management strategies during the 2011 preseason in United States high school football programs. Cross-sectional study; Level of evidence, 3. A self-administered online questionnaire addressing the incidence of exertional heat stroke events and utilization of exertional heat stroke management strategies (eg, removing athlete's football equipment, calling Emergency Medical Services [EMS]) was completed in May to June 2012 by 1142 (18.0%) athletic trainers providing care to high school football athletes during the 2011 preseason. Among all respondents, 20.3% reported treating at least 1 exertional heat stroke event. An average of 0.50 ± 1.37 preseason exertional heat stroke events were treated per program. Athletic trainers responding to exertional heat stroke reported using an average of 6.6 ± 1.8 management strategies. The most common management strategies were low-level therapeutic interventions such as removing the athlete's football equipment (98.2%) and clothing (77.8%) and moving the athlete to a shaded area (91.6%). Few athletic trainers reported active management strategies such as calling EMS (29.3%) or using a rectal thermometer to check core body temperature (0.9%). Athletic trainers in states with mandated preseason heat acclimatization guidelines reported a higher utilization of management strategies such as cooling the athlete through air conditioning (90.1% vs 65.0%, respectively; P football programs. The standard of care is (and should be) to treat proactively; therefore, treatment is not a perfect proxy for incidence. Nevertheless, there is an urgent need for improved education and awareness of

Reactions of stabilized Criegee Intermediates

Science.gov (United States)

Vereecken, Luc; Harder, Hartwig; Novelli, Anna

2014-05-01

Carbonyl oxides (Criegee intermediates) were proposed as key intermediates in the gas phase ozonolysis of alkenes in 1975 by Rudolf Criegee. Despite the importance of ozonolysis in atmospheric chemistry, direct observation of these intermediates remained elusive, with only indirect experimental evidence for their role in the oxidation of hydrocarbons, e.g. through scavenging experiments. Direct experimental observation of stabilized CI has only been achieved since 2008. Since then, a concerted effort using experimental and theoretical means is in motion to characterize the chemistry and kinetics of these reactive intermediates. We present the results of theoretical investigations of the chemistry of Criegee intermediates with a series of coreactants which may be of importance in the atmosphere, in experimental setups, or both. This includes the CI+CI cross-reaction, which proceeds with a rate coefficient near the collision limit and can be important in experimental conditions. The CI + alkene reactions show strong dependence of the rate coefficient depending on the coreactants, but is generally found to be rather slow. The CI + ozone reaction is sufficiently fast to occur both in experiment and the free troposphere, and acts as a sink for CI. The reaction of CI with hydroperoxides, ROOH, is complex, and leads both to the formation of oligomers, as to the formation of reactive etheroxides, with a moderately fast rate coefficient. The importance of these reactions is placed in the context of the reaction conditions in different atmospheric environments ranging from unpolluted to highly polluted.

Epistemic beliefs of middle and high school students in a problem-based, scientific inquiry unit: An exploratory, mixed methods study

Science.gov (United States)

Gu, Jiangyue

Epistemic beliefs are individuals' beliefs about the nature of knowledge, how knowledge is constructed, and how knowledge can be justified. This study employed a mixed-methods approach to examine: (a) middle and high school students' self-reported epistemic beliefs (quantitative) and epistemic beliefs revealed from practice (qualitative) during a problem-based, scientific inquiry unit, (b) How do middle and high school students' epistemic beliefs contribute to the construction of students' problem solving processes, and (c) how and why do students' epistemic beliefs change by engaging in PBL. Twenty-one middle and high school students participated in a summer science class to investigate local water quality in a 2-week long problem-based learning (PBL) unit. The students worked in small groups to conduct water quality tests at in their local watershed and visited several stakeholders for their investigation. Pretest and posttest versions of the Epistemological Beliefs Questionnaire were conducted to assess students' self-reported epistemic beliefs before and after the unit. I videotaped and interviewed three groups of students during the unit and conducted discourse analysis to examine their epistemic beliefs revealed from scientific inquiry activities and triangulate with their self-reported data. There are three main findings from this study. First, students in this study self-reported relatively sophisticated epistemic beliefs on the pretest. However, the comparison between their self-reported beliefs and beliefs revealed from practice indicated that some students were able to apply sophisticated beliefs during the unit while others failed to do so. The inconsistency between these two types of epistemic beliefs may due to students' inadequate cognitive ability, low validity of self-report measure, and the influence of contextual factors. Second, qualitative analysis indicated that students' epistemic beliefs of the nature of knowing influenced their problem

The intermediate endpoint effect in logistic and probit regression

Science.gov (United States)

MacKinnon, DP; Lockwood, CM; Brown, CH; Wang, W; Hoffman, JM

2010-01-01

Background An intermediate endpoint is hypothesized to be in the middle of the causal sequence relating an independent variable to a dependent variable. The intermediate variable is also called a surrogate or mediating variable and the corresponding effect is called the mediated, surrogate endpoint, or intermediate endpoint effect. Clinical studies are often designed to change an intermediate or surrogate endpoint and through this intermediate change influence the ultimate endpoint. In many intermediate endpoint clinical studies the dependent variable is binary, and logistic or probit regression is used. Purpose The purpose of this study is to describe a limitation of a widely used approach to assessing intermediate endpoint effects and to propose an alternative method, based on products of coefficients, that yields more accurate results. Methods The intermediate endpoint model for a binary outcome is described for a true binary outcome and for a dichotomization of a latent continuous outcome. Plots of true values and a simulation study are used to evaluate the different methods. Results Distorted estimates of the intermediate endpoint effect and incorrect conclusions can result from the application of widely used methods to assess the intermediate endpoint effect. The same problem occurs for the proportion of an effect explained by an intermediate endpoint, which has been suggested as a useful measure for identifying intermediate endpoints. A solution to this problem is given based on the relationship between latent variable modeling and logistic or probit regression. Limitations More complicated intermediate variable models are not addressed in the study, although the methods described in the article can be extended to these more complicated models. Conclusions Researchers are encouraged to use an intermediate endpoint method based on the product of regression coefficients. A common method based on difference in coefficient methods can lead to distorted

1991-01-01

The Environmental Protection Agency has evaluated the impacts of HVAC systems and building dynamics on radon concentrations in 26 schools across the United States. Diagnostic data indicated that radon was not the only indoor air pollutant in these schools. As a result, an essential step in the School Evaluation Program is determination of the feasibility of using HVAC technology for radon remediation in addition to general indoor air improvement. In 1990, the EPA sponsored the HVAC retrofit of two schools in Maine. This paper presents the information gained by these case studies. First, the extensive pre-retrofit diagnostics and characterizations of the two schools are reviewed. Then follows a discussion of why and how the HVAC systems, including unit ventilators, central air-handling units, and heat recovery ventilation, were retrofitted. Finally, an appraisal of the post-retrofit radon and CO 2 levels is made, along with presentation of related data such as retrofit costs and energy and comfort impacts

Gravity with Intermediate Goods Trade

Directory of Open Access Journals (Sweden)

Sujin Jang

2017-12-01

Full Text Available This paper derives the gravity equation with intermediate goods trade. We extend a standard monopolistic competition model to incorporate intermediate goods trade, and show that the gravity equation with intermediates trade is identical to the one without it except in that gross output should be used as the output measure instead of value added. We also show that the output elasticity of trade is significantly underestimated when value added is used as the output measure. This implies that with the conventional gravity equation, the contribution of output growth can be substantially underestimated and the role of trade costs reduction can be exaggerated in explaining trade expansion, as we demonstrate for the case of Korea's trade growth between 1995 and 2007.

The packaging and transport of low and intermediate level radioactive wastes

International Nuclear Information System (INIS)

Grover, J.R.; Price, M.S.T.

1985-01-01

Up to the present time, the majority of the radioactive waste which has been transported in the United Kingdom has been low level waste for disposal in the trenches of the shallow burial site operated by British Nuclear Fuels plc at Drigg and also the packaged waste destined for sea disposal in the annual operation. However, the main bulk of the low and intermediate level wastes which have been generated over the last quarter century remain in store at the various nuclear sites where it originated. Before significant packaging and transport of intermediate level wastes takes place it is desirable to examine the sources and types of wastes, the immobilisation and packaging processes and plants, the transport, and the problems of handling of packages at future land repositories. Optimisation of the packaging and transport must take account of both the upstream and downstream con=straints as well as the implications of complying with both the IAEA Transport Regulations and radiological protection guidelines. Packages for sea disposal must in addition comply with the requirements of the London Dumping Convention and the NEA guidelines. (author)

Classical model of intermediate statistics

International Nuclear Information System (INIS)

Kaniadakis, G.

1994-01-01

In this work we present a classical kinetic model of intermediate statistics. In the case of Brownian particles we show that the Fermi-Dirac (FD) and Bose-Einstein (BE) distributions can be obtained, just as the Maxwell-Boltzmann (MD) distribution, as steady states of a classical kinetic equation that intrinsically takes into account an exclusion-inclusion principle. In our model the intermediate statistics are obtained as steady states of a system of coupled nonlinear kinetic equations, where the coupling constants are the transmutational potentials η κκ' . We show that, besides the FD-BE intermediate statistics extensively studied from the quantum point of view, we can also study the MB-FD and MB-BE ones. Moreover, our model allows us to treat the three-state mixing FD-MB-BE intermediate statistics. For boson and fermion mixing in a D-dimensional space, we obtain a family of FD-BE intermediate statistics by varying the transmutational potential η BF . This family contains, as a particular case when η BF =0, the quantum statistics recently proposed by L. Wu, Z. Wu, and J. Sun [Phys. Lett. A 170, 280 (1992)]. When we consider the two-dimensional FD-BE statistics, we derive an analytic expression of the fraction of fermions. When the temperature T→∞, the system is composed by an equal number of bosons and fermions, regardless of the value of η BF . On the contrary, when T=0, η BF becomes important and, according to its value, the system can be completely bosonic or fermionic, or composed both by bosons and fermions

Full Text Available With the development of educational technology, the concept of technology-enhanced multimedia instructions is using widely in the educational settings. Technology can be employed in teaching different skills such as listening, reading, speaking and writing. Among these skills, reading comprehension is the skill in which EFL learners have some problems to master. Regarding this issue, the present study aimed at investigating the effect of video materials on improving reading comprehension of Iranian intermediate EFL learners. A Longman Placement Test was administered to 30 EFL learners to ensure that learners are at the same level of proficiency. The students were chosen from the state high schools in Chabahar.  The participants were regarded as intermediate learners and were divided into two groups (one experimental group and one control group. Then, a pre-test of reading comprehension was administered to assess the participants’ reading comprehension. The participants of experimental group used video files to improve their reading comprehension while the control group received conventional approaches of teaching reading comprehension. Finally, all the participants were assigned a 40-item multiple-choice reading comprehension post-test. The results of the study indicated that video materials had a significant effect on promoting reading comprehension of Iranian intermediate EFL learners (p = .000, <.05.

Neutron and high-energy X-ray diffraction measurements have been carried out at KENS-KEK and SPring-8, in order to investigate detailed structures of amorphous GeSe{sub 2} prepared by the rapid quenching method. Considerable intermediate-range ordering is evident from the presence of a first sharp diffraction peak at low magnetides of the scattering vector. Well-defined first and second peaks are found at around 2.36 and 3.90 A in the pair distribution function g(r). A small shoulder related to the existence of edge-sharing tetrahedral units is observed at a shorter r side of the second peak in g(r). Partial distribution functions, partial structure factors and bond-angle distributions can be obtained by Reverse Monte Carlo simulation. Results suggest that there are homo-polar bonds in tetrahedral structural units, and then the glass network is constructed by not only corner-sharing but also edge-sharing tetrahedra.

2016-10-01

Using a nationally representative sample of 1,189 immigrant youth in American high schools, we examine whether the quality of education in their country of origin is related to post-migration math achievement in the 9th grade. To measure the quality of their education in the country of origin, we use country-specific average test scores from two international assessments: the Programme for International Student Assessment (PISA) and the Trends in International Mathematics and Science Study (TIMSS). We find that the average PISA or TIMSS scores for immigrant youth's country of origin are positively associated with their performance on the 9th grade post-migration math assessment. We also find that each year spent in the United States is positively associated with performance on the 9th grade post-migration math assessment, but this effect is strongest for immigrants from countries with low PISA/TIMSS scores.

Dinkes, Cataldi, and Lin-Kelly (2007) claims that 78% of public schools reported one or more violent incidents during the 2005/2006 school year. School shootings are a rare but real threat on school campuses. Shootings at private schools are even less frequent with only a few recorded examples in the United States. This case study examines how a…

Complete Structure of an Epithelial Keratin Dimer: Implications for Intermediate Filament Assembly.

Directory of Open Access Journals (Sweden)

David J Bray

Full Text Available Keratins are cytoskeletal proteins that hierarchically arrange into filaments, starting with the dimer sub-unit. They are integral to the structural support of cells, in skin, hair and nails. In skin, keratin is thought to play a critical role in conferring the barrier properties and elasticity of skin. In general, the keratin dimer is broadly described by a tri-domain structure: a head, a central rod and a tail. As yet, no atomistic-scale picture of the entire dimer structure exists; this information is pivotal for establishing molecular-level connections between structure and function in intermediate filament proteins. The roles of the head and tail domains in facilitating keratin filament assembly and function remain as open questions. To address these, we report results of molecular dynamics simulations of the entire epithelial human K1/K10 keratin dimer. Our findings comprise: (1 the first three-dimensional structural models of the complete dimer unit, comprising of the head, rod and tail domains; (2 new insights into the chirality of the rod-domain twist gained from analysis of the full domain structure; (3 evidence for tri-subdomain partitioning in the head and tail domains; and, (4 identification of the residue characteristics that mediate non-covalent contact between the chains in the dimer. Our findings are immediately applicable to other epithelial keratins, such as K8/K18 and K5/K14, and to intermediate filament proteins in general.

Search for intermediate vector bosons

International Nuclear Information System (INIS)

Cline, D.B.; Rubbia, C.; van der Meer, S.

1982-01-01

Over the past 15 years a new class of unified theories has been developed to describe the forces acting between elementary particles. The most successful of the new theories establishes a link between electromagnetism and the weak force. A crucial prediction of this unified electroweak theory is the existence of three massive particles called intermediate vector bosons. If these intermediate vector bosons exist and if they have properties attributed to them by electroweak theory, they should soon be detected, as the world's first particle accelerator with enough energy to create such particles has recently been completed at the European Organization for Nuclear Research (CERN) in Geneva. The accelerator has been converted to a colliding beam machine in which protons and antiprotons collide head on. According to electroweak theory, intermediate vector bosons can be created in proton-antiproton collisions. (SC)

Formation, structure, and stability of MHD intermediate shocks

International Nuclear Information System (INIS)

Wu, C.C.

1990-01-01

Contrary to the usual belief that MHD intermediate shocks are extraneous, the author has recently shown by numerical solutions of dissipative MHD equations that intermediate shocks are admissible and can be formed through nonlinear wave steepening from continuous waves. In this paper, the formation, structure and stability of intermediate shocks in dissipative MHD are considered in detail. The differences between the conventional theory and his are pointed out and clarified. He shows that all four types of intermediate shocks can be formed from smooth waves. He also shows that there are free parameters in the structure of the intermediate shocks, and that these parameters are related to the shock stability. In addition, he shows that a rotational discontinuity can not exist with finite width, indicate how this is related to the existence of time-dependent intermediate shocks, and show why the conventional theory is not a good approximation to dissipative MHD solutions whenever there is rotation in magnetic field

Marissa Yanara de Godoy Lima

2017-08-01

Full Text Available To government resources be earmarked for equality and just education for every society, it is important that public managers make decisions and measures that address this need and are more effective. Thus, there is the understanding that measuring education costs adequately, relating such costs to students' school performance is necessary for the definition that costs are used for educational development. Based on this premise, the article aims to analyze how possible relationships between costs, performance and structure of the different elementary school units in the city of Cambé / PR. This study was carried out from the analysis of the distribution of resources invested in primary education in a small municipality in the north of Paraná. For a data analysis, a descriptive statistic was used, as was the non-parametric correlation test. It was verified that the schools that obtained the highest cost / student did not necessarily present better performance in the indicators of quality of the Basic Education Development Index (IDEB, evidencing a significant asymmetry of the cost / student ratio existing among the schools surveyed.

Partially folded intermediates during trypsinogen denaturation

Directory of Open Access Journals (Sweden)

Martins N.F.

1999-01-01

Full Text Available The equilibrium unfolding of bovine trypsinogen was studied by circular dichroism, differential spectra and size exclusion HPLC. The change in free energy of denaturation was = 6.99 ± 1.40 kcal/mol for guanidine hydrochloride and = 6.37 ± 0.57 kcal/mol for urea. Satisfactory fits of equilibrium unfolding transitions required a three-state model involving an intermediate in addition to the native and unfolded forms. Size exclusion HPLC allowed the detection of an intermediate population of trypsinogen whose Stokes radii varied from 24.1 ± 0.4 Å to 26.0 ± 0.3 Å for 1.5 M and 2.5 M guanidine hydrochloride, respectively. During urea denaturation, the range of Stokes radii varied from 23.9 ± 0.3 Å to 25.7 ± 0.6 Å for 4.0 M and 6.0 M urea, respectively. Maximal intrinsic fluorescence was observed at about 3.8 M urea with 8-aniline-1-naphthalene sulfonate (ANS binding. These experimental data indicate that the unfolding of bovine trypsinogen is not a simple transition and suggest that the equilibrium intermediate population comprises one intermediate that may be characterized as a molten globule. To obtain further insight by studying intermediates representing different stages of unfolding, we hope to gain a better understanding of the complex interrelations between protein conformation and energetics.

On the interrelation of multiplication and division in secondary school children

Directory of Open Access Journals (Sweden)

Stefan eHuber

2013-10-01

Full Text Available Multiplication and division are conceptually inversely related: Each division problem can be transformed into as a multiplication problem and vice versa. Recent research has indicated strong developmental parallels between multiplication and division in primary school children. In this study, we were interested in (i whether these developmental parallels persist into secondary school, (ii whether similar developmental parallels can be observed for simple and complex problems, (iii whether skill level modulates this relationship, and (iv whether the correlations are specific and not driven by general cognitive or arithmetic abilities.Therefore, we assessed performance of 5th and 6th graders attending two secondary school types of the German educational system in simple and complex multiplication as well as division while controlling for nonverbal intelligence, short-term memory, and other arithmetic abilities. Accordingly, we collected data from students differing in skills levels due to either age (5th and 6th grade or school type (general and intermediate secondary school.We observed moderate to strong bivariate and partial correlations between multiplication and division with correlations being higher for simple tasks but nevertheless reliable for complex tasks. Moreover, the association between simple multiplication and division depended on students’ skill levels as reflected by school types, but not by age. Partial correlations were higher for intermediate than for general secondary school children.In sum, these findings emphasize the importance of the inverse relationship between multiplication and division which persists into later developmental stages. However, evidence for skill-related differences in the relationship between multiplication and division was restricted to the differences for school types.

Racial/Ethnic Patterns of Kindergarten School Enrollment in the United States.

Science.gov (United States)

Lawrence, Elizabeth; Mollborn, Stefanie

2017-09-01

Enrollment into unequal schools at the start of formal education is an important mechanism for the reproduction of racial/ethnic educational inequalities. We examine whether there are racial/ethnic differences in school enrollment options at kindergarten, the start of schooling. We use nationally representative data from the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B) to model whether parents seek information about their child's school before enrolling, whether parents move to a location so that a child can attend a certain school, or whether parents enroll their child in a school other than the assigned public school. Results indicate that enrollment patterns differ greatly across race/ethnicity. Whereas Black families are the most likely to seek information on a school's performance, White families are the most likely to use the elite option of choosing their residential location to access a particular school. These differences persist when controlling for socioeconomic status and sociogeographic location. Kindergarten enrollment patterns preserve the advantages of White families, perpetuating racial/ethnic disparities through multiple institutions and contributing to intergenerational processes of social stratification. Research should continue to examine specific educational consequences of housing inequities and residential segregation.

Grinshteyn, Erin; Yang, Y T

2017-02-01

We examined the relationship between exposure to electronic bullying and absenteeism as a result of being afraid. This multivariate, multinomial regression analysis of the 2013 Youth Risk Behavior Survey data assessed the association between experiencing electronic bullying in the past year and how often students were absent in the last month due to feeling unsafe at/in transit to school. The model controlled for other predictors of school absence including demographics, physical/behavioral health, and risk factors. Missing data were multiply imputed. Electronic bullying was significantly associated with absences. Controlling for model covariates, the relative risk of missing 1 day of school was 1.77 times higher, the relative risk of missing 2 to 3 days of school per month increased by a factor of 2.08, and the relative risk of missing 4 or more days of school per month increased by a factor of 1.77 for those who experienced electronic bullying in the past year compared with those who were not electronically bullied. Electronic bullying's association with absenteeism places it among already recognized negative influences such as depression and binge drinking, necessitating schools to implement policies to mediate the resulting harmful effects. © 2017, American School Health Association.

Present status of intermediate band solar cell research

International Nuclear Information System (INIS)

Cuadra, L.; Marti, A.; Luque, A.

2004-01-01

The intermediate band solar cell is a theoretical concept with the potential for exceeding the performance of conventional single-gap solar cells. This novel photovoltaic converter bases its superior theoretical efficiency over single-gap solar cells by enhancing its photogenerated current, via the two-step absorption of sub-band gap photons, without reducing its output voltage. This is achieved through a material with an electrically isolated and partially filled intermediate band located within a higher forbidden gap. This material is commonly named intermediate band material. This paper centres on summarising the present status of intermediate band solar cell research. A number of attempts, which aim to implement the intermediate band concept, are being followed: the direct engineering of the intermediate band material, its implementation by means of quantum dots and the highly porous material approach. Among other sub-band gap absorbing proposals, there is a renewed interest on the impurity photovoltaic effect, the quantum well solar cells and the particularly promising proposal for the use of up- and down-converters

Design of an intelligent flight instrumentation unit using embedded RTOS

Estrada-Marmolejo, R.; García-Torales, G.; Torres-Ortega, H. H.; Flores, J. L.

2011-09-01

Micro Unmanned Aerial Vehicles (MUAV) must calculate its spatial position to control the flight dynamics, which is done by Inertial Measurement Units (IMUs). MEMS Inertial sensors have made possible to reduce the size and power consumption of such units. Commonly the flight instrumentation operates independently of the main processor. This work presents an instrumentation block design, which reduces size and power consumption of the complete system of a MUAV. This is done by coupling the inertial sensors to the main processor without considering any intermediate level of processing aside. Using Real Time Operating Systems (RTOS) reduces the number of intermediate components, increasing MUAV reliability. One advantage is the possibility to control several different sensors with a single communication bus. This feature of the MEMS sensors makes a smaller and less complex MUAV design possible.

In the United States (US), an estimated 300,000 sports-related concussions occur annually. Among individuals 15 to 24 years of age, sports are second only to motor vehicle crashes as the leading cause of concussions. To investigate the epidemiology of concussions in high school athletes by comparing rates and patterns of concussion among 20 sports. Descriptive epidemiology study. Using an Internet-based data collection tool, RIO, certified athletic trainers from a large, nationally disperse sample of US high schools reported athlete exposure and injury data for 20 sports during the 2008-2010 academic years. During the study period, 1936 concussions were reported during 7,780,064 athlete-exposures (AEs) for an overall injury rate of 2.5 per 10,000 AEs. The injury rate was higher in competition (6.4) than practice (1.1) (rate ratio [RR], 5.7; 95% confidence interval [CI], 5.2-6.3). The majority of concussions resulted from participation in football (47.1%, n = 912), followed by girls' soccer (8.2%, n = 159), boys' wrestling (5.8%, n = 112), and girls' basketball (5.5%, n = 107). Football had the highest concussion rate (6.4), followed by boys' ice hockey (5.4) and boys' lacrosse (4.0). Concussions represented a greater proportion of total injuries among boys' ice hockey (22.2%) than all other sports studied (13.0%) (injury proportion ratio [IPR], 1.7; 95% CI, 1.4-2.1; P sports, girls had a higher concussion rate (1.7) than boys (1.0) (RR, 1.7; 95% CI, 1.4-2.0). The most common mechanisms of injury were player-player contact (70.3%) and player-playing surface contact (17.2%). In more than 40% of athletes in sports other than girls' swimming and girls' track, concussion symptoms resolved in 3 days or less. Athletes most commonly returned to play in 1 to 3 weeks (55.3%), with 22.8% returning in less than 1 week and 2.0% returning in less than 1 day. Although interest in sports-related concussions is usually focused on full-contact sports like football and ice hockey

Terry-McElrath, Yvonne M; OʼMalley, Patrick M; Johnston, Lloyd D

2014-01-01

Examine energy drink/shot and regular and diet soft drink use among United States secondary school students in 2010-2011, and associations between such use and substance use. We used self-reported data from cross-sectional surveys of nationally representative samples of 8th-, 10th-, and 12th-grade students and conducted multivariate analyses examining associations between beverage and substance use, controlling for individual and school characteristics. Approximately 30% of students reported consuming energy drinks or shots; more than 40% reported daily regular soft drink use, and about 20% reported daily diet soft drink use. Beverage consumption was strongly and positively associated with past 30-day alcohol, cigarette, and illicit drug use. The observed associations between energy drinks and substance use were significantly stronger than those between regular or diet soft drinks and substance use. This correlational study indicates that adolescent consumption of energy drinks/shots is widespread and that energy drink users report heightened risk for substance use. This study does not establish causation between the behaviors. Education for parents and prevention efforts among adolescents should include education on the masking effects of caffeine in energy drinks on alcohol- and other substance-related impairments, and recognition that some groups (such as high sensation-seeking youth) may be particularly likely to consume energy drinks and to be substance users.

About 10% of patients admitted to a chest pain unit (CPU) exhibit atrial fibrillation (AF). To determine whether calcium scores (CS) are superior over common risk scores for coronary artery disease (CAD) in patients presenting with atypical chest pain, newly diagnosed AF, and intermediate pretest probability for CAD within the CPU. In 73 subjects, CS was related to the following risk scores: Global Registry of Acute Coronary Events (GRACE) score, including a new model of a frequency-normalized approach; Thrombolysis In Myocardial Infarction score; European Society of Cardiology Systematic Coronary Risk Evaluation (SCORE); Framingham risk score; and Prospective Cardiovascular Münster Study score. Revascularization rates during index stay were assessed. Median CS was 77 (interquartile range, 1-270), with higher values in men and the left anterior descending artery. Only the modified GRACE (ρ = 0.27; P = 0.02) and the SCORE (ρ = 0.39; P risk scores and calcium burden, as well as revascularization rates during index stay, were low. By contrast, the determination of CS may be used as an additional surrogate marker in risk stratification in AF patients with intermediate pretest likelihood for CAD admitted to a CPU. © 2016 Wiley Periodicals, Inc.

In this study, in situ exposure assessment of both electric and magnetic fields of different intermediate frequency (IF) sources is investigated. The authors investigated smart boards and touch-screens, energy-saving bulbs, fluorescent lamps, a portable hearing unit and an electro-surgical unit (ESU). For most of these sources, the electric field is the dominating quantity. International Commission on Non-Ionizing Radiation Protection reference levels are exceeded for touch-screens (44 kHz: up to 155.7 V m -1 at 5 cm), energy-saving bulbs (38-52 kHz: up to 117.3 V m -1 ), fluorescent lamps (52 kHz: up to 471 V m -1 at 5 cm) and ESUs (up to 920 kHz: 792 V m -1 at 0.5 cm). Magnetic field strengths up to 1.8 and 10.5 A m -1 were measured close to the ESU and portable hearing unit (69 V m -1 ), respectively. Large differences of measured field values exist among the various operating modes of the IF equipment. Compliance distances for general public range from 15.3 cm (touch-screen) to 25 cm (fluorescent lamps). (authors)

Taeyong, Sung; Hyun Gook, Kang

2001-01-01

Even though the conventional probabilistic safety assessment methods are immature for applying to microprocessor-based digital systems, practical needs force to apply it. In the Korea, UCN 5 and 6 units are being constructed and Korean Next Generation Reactor is being designed using the digital instrumentation and control equipment for the safety related functions. Korean regulatory body requires probabilistic safety assessment. This paper analyzes the difficulties on the assessment of digital systems and suggests an intermediate framework for evaluating their safety using fault tree models. The framework deals with several important characteristics of digital systems including software modules and fault-tolerant features. We expect that the analysis result will provide valuable design feedback. (authors)

2016-01-01

To determine the associations of systemic diseases with intermediate uveitis. The medical records of 50 consecutive cases with intermediate uveitis referred to The Eye Center in Riyadh, Saudi Arabia, were reviewed. Age- and sex-matched patients without uveitis served as controls. Patients had complete ophthalmic and medical examinations. There were 27 male and 23 female patients. Mean age was 29 years with a range of 5-62 years. Overall, 21 cases (42%) had systemic disorders associated with intermediate uveitis and 29 cases (58%) had no associated systemic disease. A total of 11 patients (22%) had asthma, 4 (8%) had multiple sclerosis, 3 (6%) had presumed ocular tuberculosis, 1 (2%) had inflammatory bowel disease, 1 (2%) had non-Hodgkin lymphoma and 1 (2%) had sarcoidosis. Evidence of systemic disease was found in 50 (5%) of the 1,000 control subjects. Bronchial asthma was found in 37 patients (3.7 %), multiple sclerosis in 9 patients (0.9%), inflammatory bowel disease in 3 patients (0.3%), and tuberculosis in 1 patient (0.1%). None of the control patients had sarcoidosis or lymphoma. There were statistically significant associations between intermediate uveitis and bronchial asthma (p = 0.0001), multiple sclerosis (p = 0.003) and tuberculosis (p = 0.0005). Bronchial asthma and multiple sclerosis were the most frequently encountered systemic diseases associated with intermediate uveitis in our patient population. Patients with intermediate uveitis should undergo careful history-taking and investigations to rule out associated systemic illness.

Full Text Available BACKGROUND: Many schools throughout the United States reported an increase in dismissals due to the 2009 influenza A H1N1 pandemic (pH1N1. During the fall months of 2009, more than 567 school dismissals were reported from the state of Michigan. In December 2009, the Michigan Department of Community Health, in collaboration with the United States Centers for Disease Control and Prevention, conducted a survey to describe the knowledge, attitudes, and practices (KAPs of households with school-aged children and classroom teachers regarding the recommended use of nonpharmaceutical interventions (NPIs to slow the spread of influenza. METHODS: A random sample of eight elementary schools (kindergarten through 5th grade was selected from each of the eight public health preparedness regions in the state. Within each selected school, a single classroom was randomly identified from each grade (K-5, and household caregivers of the classroom students and their respective teachers were asked to participate in the survey. RESULTS: In total, 26% (2,188/8,280 of household caregivers and 45% (163/360 of teachers from 48 schools (of the 64 sampled responded to the survey. Of the 48 participating schools, 27% (13 experienced a school dismissal during the 2009 fall term. Eighty-seven percent (1,806/2,082 of caregivers and 80% (122/152 of teachers thought that the 2009 influenza A H1N1 pandemic was severe, and >90% of both groups indicated that they told their children/students to use NPIs, such as washing hands more often and covering coughs with tissues, to prevent infection with influenza. CONCLUSIONS: Knowledge and instruction on the use of NPIs appeared to be high among household caregivers and teachers responding to the survey. Nevertheless, public health officials should continue to explain the public health rationale for NPIs to reduce pandemic influenza. Ensuring this information is communicated to household caregivers and teachers through trusted sources is

Orthorhombic Intermediate State in the Zinc Blende to Rocksalt Transformation Path of SiC at High Pressure

International Nuclear Information System (INIS)

Catti, Michele

2001-01-01

The mechanism of the B3/B1 phase transition of SiC has been investigated by periodic LCAO-DFT least-enthalpy calculations. A new transformation pathway, based on a Pmm2 orthorhombic intermediate state with two SiC units per cell, is found to be energetically favored over the traditional R3m mechanism. The computed activation enthalpy is 0.75eV/SiC unit at the predicted transition pressure of 92GPa (B3LYP functional). Activation enthalpy and activation volume vs pressure are analyzed to characterize the kinetic aspects of the transformation

Olympia, Robert P; Weber, Christopher; Brady, Jodi; Ho, Susana

2017-11-01

The aim of the study was to determine the compliance of school transportation staff and school buses with recommendations for the safe transportation of children to and from school and school-related activities. An electronic questionnaire was distributed to school transportation staff represented by the International Brotherhood of Teamsters during the 2013-2014 academic year. Analysis was performed on 558 completed questionnaires (13% usable response rate). Responders had previous training in first aid (89%), basic life support (28%), and cardiopulmonary resuscitation (52%). Seventy-eight percent of school buses in our sample had restraint devices and 87% had seat belt cutters. Responders reported the immediate availability of the following on their bus: communication devices (81%), first aid kits (97%), fire extinguishers (89%), automated external defibrillators (1%), and epinephrine autoinjectors (2%). Thirty percent of responders have had no previous training in the management of emergencies such as trouble breathing, severe allergic reaction, seizures, cardiac arrest or unresponsiveness, and head, neck, or extremity trauma. Thirteen percent of responders are unfamiliar with or have had no previous training on protocols regarding emergency shelters and community evacuation plans in the event of a disaster. Variability exists in the compliance of school transportation staff and school buses with recommendations for the safe transportation of children. Areas for improvement were identified, such as educating school transportation staff in the recognition and initial management of pediatric emergencies, ensuring the presence of restraint devices, increasing the immediate availability of certain emergency medications and equipment, and familiarizing school transportation staff with designated emergency shelters and community evacuation plans.

Tse, Kenneth

The purpose of this study was to understand how science teachers reacted to the high stakes accountability and standardized testing in California. In a multiple case study of middle and intermediate schools in Southern California, four research questions focused on the perceptions of secondary science teachers and how they responded to the changes in the accountability specifically geared towards science as a content area, the pedagogical skills teachers were using both outside and inside of the classroom that impact instruction, the pedagogical training received that related specifically to the content standards, the tools or impediments that existed for teachers to successfully utilize these pedagogical methods and types of support and assistance the school site administration and/or school district offered in learning about the California Science Standards and the STAR test. Interviews were conducted with multiple middle/intermediate school teachers, science department chairpersons and school site administrators to gather information about what the classroom teachers were doing pedagogically to improve student performance on the STAR tests. Moreover, the study described the issues that supported the professional development of the teacher and what schools and districts were doing to support them.

2016-01-08

Electronic cigarette (e-cigarette) use has increased considerably among U.S. youths since 2011. Tobacco use among youths in any form, including e-cigarettes, is unsafe. Tobacco product advertising can persuade youths to start using tobacco. CDC analyzed data from the 2014 National Youth Tobacco Survey to estimate the prevalence of e-cigarette advertisement exposure among U.S. middle school and high school students. The 2014 National Youth Tobacco Survey, a school-based survey of middle school and high school students in grades 6-12, included 22,007 participants. Exposure to e-cigarette advertisements (categorized as "sometimes," "most of the time," or "always") was assessed for four sources: retail stores, Internet, TV and movies, and newspapers and magazines. Weighted exposure estimates were assessed overall and by school type, sex, race/ethnicity, and grade. In 2014, 68.9% of middle and high school students (18.3 million) were exposed to e-cigarette advertisements from at least one source. Among middle school students, exposure was highest for retail stores (52.8%), followed by Internet (35.8%), TV and movies (34.1%), and newspapers and magazines (25.0%). Among high school students, exposure was highest for retail stores (56.3%), followed by Internet (42.9%), TV and movies (38.4%), and newspapers and magazines (34.6%). Among middle school students, 23.4% reported exposure to e-cigarette advertising from one source, 17.4% from two sources, 13.7% from three sources, and 11.9% from four sources. Among high school students, 21.1% reported exposure to e-cigarette advertising from one source, 17.0% from two sources, 14.5% from three sources, and 18.2% from four sources. Approximately seven in 10 U.S. middle and high school students were exposed to e-cigarette advertisements in 2014. Exposure to e-cigarette advertisements might contribute to increased use of e-cigarettes among youths. Multiple approaches are warranted to reduce youth e-cigarette use and exposure to e

Isoporphyrin Intermediate in Heme Oxygenase Catalysis

Science.gov (United States)

Evans, John P.; Niemevz, Fernando; Buldain, Graciela; de Montellano, Paul Ortiz

2008-01-01

Human heme oxygenase-1 (hHO-1) catalyzes the O2- and NADPH-dependent oxidation of heme to biliverdin, CO, and free iron. The first step involves regiospecific insertion of an oxygen atom at the α-meso carbon by a ferric hydroperoxide and is predicted to proceed via an isoporphyrin π-cation intermediate. Here we report spectroscopic detection of a transient intermediate during oxidation by hHO-1 of α-meso-phenylheme-IX, α-meso-(p-methylphenyl)-mesoheme-III, and α-meso-(p-trifluoromethylphenyl)-mesoheme-III. In agreement with previous experiments (Wang, J., Niemevz, F., Lad, L., Huang, L., Alvarez, D. E., Buldain, G., Poulos, T. L., and Ortiz de Montellano, P. R. (2004) J. Biol. Chem. 279, 42593–42604), only the α-biliverdin isomer is produced with concomitant formation of the corresponding benzoic acid. The transient intermediate observed in the NADPH-P450 reductase-catalyzed reaction accumulated when the reaction was supported by H2O2 and exhibited the absorption maxima at 435 and 930 nm characteristic of an isoporphyrin. Product analysis by reversed phase high performance liquid chromatography and liquid chromatography electrospray ionization mass spectrometry of the product generated with H2O2 identified it as an isoporphyrin that, on quenching, decayed to benzoylbiliverdin. In the presence of H218O2, one labeled oxygen atom was incorporated into these products. The hHO-1-isoporphyrin complexes were found to have half-lives of 1.7 and 2.4 h for the p-trifluoromethyl- and p-methyl-substituted phenylhemes, respectively. The addition of NADPH-P450 reductase to the H2O2-generated hHO-1-isoporphyrin complex produced α-biliverdin, confirming its role as a reaction intermediate. Identification of an isoporphyrin intermediate in the catalytic sequence of hHO-1, the first such intermediate observed in hemoprotein catalysis, completes our understanding of the critical first step of heme oxidation.

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

Sakich, J.D.; Lenk, D.W.; Koepfinger, J.L.

1992-01-01

This paper introduces the first commercially available polymer enclosed intermediate class metal oxide surge arrester. It describes the unique construction of the design, including reduced size, increased flexibility, a collared seal on the polymer housing and an open webbed fiberglass-epoxy module which houses the metal oxide disc elements. Performance advantages are discussed. These include improved short term contamination performance of the insulator-like polymer design when compared to multi-unit porcelain housed designs. Data will show that polymer housed open-webbed fiberglass module construction extends the pressure relief capability beyond that of typical porcelain enclosed designs. The capability of the polymer enclosed design to withstand repeated pressure relief tests, simulating system reclose on a failed arrester, is also discussed. This paper discusses the circumstances at one utility which has considered utilizing polymer enclosed intermediate class arresters to effectively upgrade their system protection capabilities

Saloor, Nooshin; Okal, Emile A.

2018-01-01

We extend to intermediate and deep earthquakes the slowness parameter Θ originally introduced by Newman and Okal (1998). Because of the increasing time lag with depth between the phases P, pP and sP, and of variations in anelastic attenuation parameters t∗ , we define four depth bins featuring slightly different algorithms for the computation of Θ . We apply this methodology to a global dataset of 598 intermediate and deep earthquakes with moments greater than 1025 dyn∗cm. We find a slight increase with depth in average values of Θ (from -4.81 between 80 and 135 km to -4.48 between 450 and 700 km), which however all have intersecting one- σ bands. With widths ranging from 0.26 to 0.31 logarithmic units, these are narrower than their counterpart for a reference dataset of 146 shallow earthquakes (σ = 0.55). Similarly, we find no correlation between values of Θ and focal geometry. These results point to stress conditions within the seismogenic zones inside the Wadati-Benioff slabs more homogeneous than those prevailing at the shallow contacts between tectonic plates.

Turbulence, aeration and bubble features of air-water flows in macro- and intermediate roughness conditions

Directory of Open Access Journals (Sweden)

Stefano Pagliara

2011-06-01

Full Text Available Free surface flows in macro- and intermediate roughness conditions have a high aeration potential causing the flow characteristics to vary with slopes and discharges. The underlying mechanism of two-phase flow characteristics in macro- and intermediate roughness conditions were analyzed in an experimental setup assembled at the Laboratory of Hydraulic Protection of the Territory (PITLAB of the University of Pisa, Italy. Crushed angular rocks and hemispherical boulders were used to intensify the roughness of the bed. Flow rates per unit width ranging between 0.03 m2/s and 0.09 m2/s and slopes between 0.26 and 0.46 were tested over different arrangements of a rough bed. Analyses were mainly carried out in the inner flow region, which consists of both bubbly and intermediate flow regions. The findings revealed that the two-phase flow properties over the rough bed were much affected by rough bed arrangements. Turbulence features of two-phase flows over the rough bed were compared with those of the stepped chute data under similar flow conditions. Overall, the results highlight the flow features in the inner layers of the two-phase flow, showing that the maximum turbulence intensity decreases with the relative submergence, while the bubble frequency distribution is affected by the rough bed elements.

2017-03-03

The LLVM intermediate representation (IR) lacks semantic constructs for depicting common high-performance operations such as parallel and concurrent execution, communication and synchronization. Currently, representing such semantics in LLVM requires either extending the intermediate form (a signi cant undertaking) or the use of ad hoc indirect means such as encoding them as intrinsics and/or the use of metadata constructs. In this paper we discuss a work in progress to explore the design and implementation of a new compilation stage and associated high-level intermediate form that is placed between the abstract syntax tree and when it is lowered to LLVM's IR. This highlevel representation is a superset of LLVM IR and supports the direct representation of these common parallel computing constructs along with the infrastructure for supporting analysis and transformation passes on this representation.

2001-01-01

A survey of US medical schools regarding the incorporation of psychosomatic (biopsychosocial) medicine topics into medical school curriculum was conducted. The perceived importance and success of this curriculum, barriers to teaching psychosomatic medicine, and curricular needs were also assessed. From August 1997 to August 1999, representatives of US medical schools were contacted to complete a survey instrument either by telephone interview or by written questionnaire. Survey responses were received from 54 of the 118 US medical schools contacted (46%). Responses were obtained from representatives of both public (57%) and private (43%) institutions. Only 20% of respondents indicated that their schools used the term "psychosomatic medicine"; the terms "behavioral medicine" (63%) and "biopsychosocial medicine" (41%) were used more frequently. Coverage of various health habits (eg, substance use and exercise) ranged from 52% to 96%. The conceptualization and/or measurement of psychosocial factors (eg, stress and social support) was taught by 80% to 93% of schools. Teaching about the role of psychosocial factors in specific disease states or syndromes ranged from 33% (renal disease) to 83% (cardiovascular disease). Coverage of treatment-related issues ranged from 44% (relaxation/biofeedback) to 98% (doctor-patient communication). Topics in psychosomatic medicine were estimated to comprise approximately 10% (median response) of the medical school curriculum. On a scale of 1 (lowest) to 10 (highest), ratings of the relative importance of this curriculum averaged 7 (SD = 2.5; range = 2-10). Student response to the curriculum varied from positive to mixed to negative. Perceived barriers to teaching psychosomatic medicine included limited resources (eg, time, money, and faculty), student and faculty resistance, and a lack of continuity among courses. Sixty-three percent of respondents expressed an interest in receiving information about further incorporation of topics in

Jorie M. Colbert-Getz

2015-10-01

Full Text Available Purpose: The situational judgment test (SJT shows promise for assessing the non-cognitive skills of medical school applicants, but has only been used in Europe. Since the admissions processes and education levels of applicants to medical school are different in the United States and in Europe, it is necessary to obtain validity evidence of the SJT based on a sample of United States applicants. Methods: Ninety SJT items were developed and Kane’s validity framework was used to create a test blueprint. A total of 489 applicants selected for assessment/interview day at the University of Utah School of Medicine during the 2014-2015 admissions cycle completed one of five SJTs, which assessed professionalism, coping with pressure, communication, patient focus, and teamwork. Item difficulty, each item’s discrimination index, internal consistency, and the categorization of items by two experts were used to create the test blueprint. Results: The majority of item scores were within an acceptable range of difficulty, as measured by the difficulty index (0.50-0.85 and had fair to good discrimination. However, internal consistency was low for each domain, and 63% of items appeared to assess multiple domains. The concordance of categorization between the two educational experts ranged from 24% to 76% across the five domains. Conclusion: The results of this study will help medical school admissions departments determine how to begin constructing a SJT. Further testing with a more representative sample is needed to determine if the SJT is a useful assessment tool for measuring the non-cognitive skills of medical school applicants.

Implementing health promotion in schools: protocol for a realist systematic review of research and experience in the United Kingdom (UK

Directory of Open Access Journals (Sweden)

Pearson Mark

2012-10-01

Full Text Available Abstract Background School-based interventions and campaigns are used to promote health and address a wide variety of public health problems. Schools are considered to be key sites for the implementation of health promotion programmes for their potential to reach the whole population in particular age-groups and instil healthy patterns of behavior early in life. However, evidence for the effectiveness of school-based health promotion interventions is highly variable. Systematic reviews of the evidence of school-based interventions tend to be highly problem- or intervention- specific, thereby missing potential generic insights into implementation and effectiveness of such programmes across problems. Methods/design A realist systematic review will be undertaken to explain how, why and in what circumstances schools can provide feasible settings for effective health promotion programmes in the United Kingdom (UK. The review will be conducted in two phases. Phase 1 will identify programme theories about implementation (ideas about what enables or inhibits effective health promotion to be delivered in a school setting. Phase 2 will test the programme theories so that they can be challenged, endorsed and/or refined. A Review Advisory Group of education and health professionals will be convened to help identify and choose potential programme theories, provide a ‘reality check’ on the clarity and explanatory strength of the mechanisms to be tested, and help shape the presentation of findings to be usable by practitioners and decision-makers. Review findings will be disseminated through liaison with decision-makers, and voluntary and professional groups in the fields of education and health.

Full Text Available A new strategy in catalytic ozonation removal method for degradation and detoxification of phenol from industrial wastewater was investigated. Magnetic carbon nanocomposite, as a novel catalyst, was synthesized and then used in the catalytic ozonation process (COP and the effects of operational conditions such as initial pH, reaction time, and initial concentration of phenol on the degradation efficiency and the toxicity assay have been investigated. The results showed that the highest catalytic potential was achieved at optimal neutral pH and the removal efficiency of phenol and COD is 98.5% and 69.8%, respectively. First-order modeling demonstrated that the reactions were dependent on the initial concentration of phenol, with kinetic constants varying from 0.038 min−1  ([phenol]o = 1500 mg/L to 1.273 min−1 ([phenol]o = 50 mg/L. Bioassay analysis showed that phenol was highly toxic to Daphnia magna (LC50 96 h=5.6 mg/L. Comparison of toxicity units (TU of row wastewater (36.01 and the treated effluent showed that TU value, after slightly increasing in the first steps of ozonation for construction of more toxic intermediates, severely reduced at the end of reaction (2.23. Thus, COP was able to effectively remove the toxicity of intermediates which were formed during the chemical oxidation of phenolic wastewaters.

Intermediate Inflation or Late Time Acceleration?

International Nuclear Information System (INIS)

Sanyal, A.K.

2008-01-01

The expansion rate of intermediate inflation lies between the exponential and power law expansion but corresponding accelerated expansion does not start at the onset of cosmological evolution. Present study of intermediate inflation reveals that it admits scaling solution and has got a natural exit form it at a later epoch of cosmic evolution, leading to late time acceleration. The corresponding scalar field responsible for such feature is also found to behave as a tracker field for gravity with canonical kinetic term.

de Apodaca, Roberto Flores; Brighton, Lauren M; Perkins, Ashley N; Jackson, Kiana N; Steege, Jessica R

2012-04-01

School-based violence, and fatal school shootings in particular, have gained increased attention in the media and psychological literature. Most reports have focused on the characteristics of perpetrators, but there is a growing awareness that school-related factors may also influence the occurrence of fatal school shootings. The current study examined several key characteristics of all schools where random (38) and targeted (96) fatal shootings occurred in the United States between 1966 and 2009. These were compared with a group (138) of schools randomly selected to represent the population of all schools in the United States. The size of a school's enrollment, urban or suburban locale, public funding, and predominantly non-white enrollment were positively associated with fatal shootings. Universities and colleges were disproportionately associated with random shootings and high schools with targeted ones. It was proposed that characteristics of schools that allow feelings of anonymity or alienation among students may help create environmental conditions associated with fatal school shootings. Implications for future research and interventions are considered.

Future possibilities with intermediate-energy neutron beams

International Nuclear Information System (INIS)

Brady, F.P.

1987-01-01

Future possibilities for using neutrons of intermediate energies (50 - 200 MeV) as a probe of the nucleus are discussed. Some of the recent thinking concerning a systematic approach for studying elastic and inelastic scattering of electrons and hadrons and the important role of medium- and intermediate-energy neutrons in such a programme is reviewed. The advantages of neutrons in this energy range over neutrons with lower energies and over intermediate-energy pions for determining nuclear-transition and ground state densities, and for distinguishing proton from neutron density (isovector sensitivity), are noted. The important role of (n,p) charge exchange reactions in nuclear excitation studies is also reviewed. Experimental methods for utilizing neutrons as probes in elastic, inelastic, and charge exchange studies at these energies are discussed

The US neutrino community gathered at the Workshop on the Intermediate Neutrino Program (WINP) at Brookhaven National Laboratory February 4-6, 2015 to explore opportunities in neutrino physics over the next five to ten years. Scientists from particle, astroparticle and nuclear physics participated in the workshop. The workshop examined promising opportunities for neutrino physics in the intermediate term, including possible new small to mid-scale experiments, US contributions to large experiments, upgrades to existing experiments, R&D plans and theory. The workshop was organized into two sets of parallel working group sessions, divided by physics topics and technology. Physics working groups covered topics on Sterile Neutrinos, Neutrino Mixing, Neutrino Interactions, Neutrino Properties and Astrophysical Neutrinos. Technology sessions were organized into Theory, Short-Baseline Accelerator Neutrinos, Reactor Neutrinos, Detector R&D and Source, Cyclotron and Meson Decay at Rest sessions.This report summarizes discussion and conclusions from the workshop.

Chen, Ling; Zhou, Hai-Yun; Deng, Qin-Ying

2007-06-01

The photolysis of nonylphenol ethoxylates with an average oligomers length of ten ethoxylate units (NPEO(10)) in aqueous solution under UV, as well as the influence of humic acid (HA) on the photolysis was studied. A 125W high-pressure mercury lamp was employed as the light source. The intermediate products from the photolysis were determined by LC-MS. The results indicated that NPEO(10) underwent direct photolysis upon exposed to UV. The degradation pathway was complex. Besides the generally proposed degradation pathway of ethylene oxide (EO) side chains shortening, the oxidation of alkyl chain and EO chain led to intermediates having both a carboxylated (as well as carbonylated) ethoxylate and alkyl chain of varying lengths. The hydrogenation of benzene ring was also detected. The kinetics data showed that the first order reaction kinetics could be well used to describe the kinetics of NPEO(10) degradation. In the presence of dissolved organic matter by HA addition, the performance of NPEO(10) photodegradation was reduced. The photolysis rate decreased with increased HA concentration.

Comments on intermediate-scale models

Some superstring-inspired models employ intermediate scales m I of gauge symmetry breaking. Such scales should exceed 10 16 GeV in order to avoid prima facie problems with baryon decay through heavy particles and non-perturbative behaviour of the gauge couplings above m I . However, the intermediate-scale phase transition does not occur until the temperature of the Universe falls below O(m W ), after which an enormous excess of entropy is generated. Moreover, gauge symmetry breaking by renormalization group-improved radiative corrections is inapplicable because the symmetry-breaking field has not renormalizable interactions at scales below m I . We also comment on the danger of baryon and lepton number violation in the effective low-energy theory. (orig.)

Computational uncertainties in silicon dioxide/plutonium intermediate neutron spectrum systems

Jaegers, P.J.

1997-01-01

In the past several years, several proposals have been made for the long-term stabilization and storage of surplus fissile materials. Many of these proposed scenarios involve systems that have an intermediate neutron energy spectrum. Such intermediate-energy systems are dominated by scattering and fission events induced by neutrons ranging in energy from 1 eV to 100keV. To ensure adequate safety margins and cost effectiveness, it is necessary to have benchmark data for these intermediate-energy spectrum systems; however, a review of the nuclear criticality benchmarks indicates that no formal benchmarks are available. Nuclear data uncertainties have been reported for some types of intermediate-energy spectrum systems. Using a variety of Monte Carlo computer codes and cross-section sets, reported significant variations in the calculated k ∞ of intermediate-energy spectrum metal/ 235 U systems. We discuss the characteristics of intermediate neutron spectrum systems and some of the computational differences that can occur in calculating the k eff of these systems

Can schools save kids' palates? Cooking from scratch in schools--the greatest food service challenge of our time.

2012-08-01

School District Food Service Departments are faced with the enormous task of feeding children in the United States up to two thirds of the meals that they consume during the week at school. The shift in food production since the 1970s produced a trend away from scratch-cooked foods and resulted in more meals created from processed foods. The United States has reached a tipping point where the health of the current generation is compromised by increasing health risks of diet-related disease. Schools have been identified as a critical environment in which there is an opportunity to effect change in what children eat. As a result, in the last 10 years, there has been a resurgence of interest in freshly prepared meals in schools. This article explores one chef’s transition from the private sector to the public sector and the experiences of working with school districts to successfully transform their school food service operations into a scratch cooking model.

To estimate the costs per relevant unit (pupils and meals) associated with improvements to school food and the potential economic and health gains that may result. Calculation of costs per relevant unit (pupils and meals) based on (i) Department for Education expenditure to support improvements in school food, 2005–2011 and (ii) measures of the changes in the number of pupils taking school lunch and the number of meals served over the same time period; plus examples of the use of linked data to predict longer-term economic and health outcomes of healthier eating at school. England. Local authorities, government departments and non-departmental public bodies. Analysis of investment over a 6-year period indicates that costs of setting up and maintaining a change organization such as the School Food Trust were low in relation to short-term benefits in nutrition and behaviour. Models that predict long-terms gains to the exchequer and to quality-adjusted life years need further elaboration. Modest levels of government investment in the delivery and promotion of healthier school food is likely to yield both short-term and long-term benefits in relation to nutrition, learning, economics and health.

An examination of sociodemographic correlates of ecstasy use among high school seniors in the United States.

2014-11-01

Although ecstasy (MDMA) use is not as prevalent in the United States (US) as it was in the early 2000s, use remains popular among adolescents and young adults. Few recent studies have examined ecstasy use in national samples among those at particularly high risk for use-adolescents approaching adulthood. Research is needed to delineate sociodemographic correlates of use in this group. Data were examined from a nationally representative sample of high school seniors in the US (modal age = 18) from the Monitoring the Future study (years 2007-2012; weighted N = 26,504). Data from all cohorts were aggregated and correlates of recent (last 12-month) use of ecstasy were examined. Roughly 4.4% of high school seniors reported use of ecstasy within the last year. Females and religious students were consistently at lower odds for use. Black and Hispanic students, and students residing with two parents, were at lower odds for ecstasy use, until controlling for other drug use. Odds of use were consistently increased for those residing in a city, students with weekly income of >$50 from a job, and students earning >$10 weekly from other sources. Lifetime use of alcohol, cigarettes, marijuana, and other illicit drugs each robustly increased odds of ecstasy use. Subgroups of high school seniors, defined by specific sociodemographic factors, and those who have used other drugs, are currently at high risk for ecstasy initiation and use. Since ecstasy is regaining popularity in the US, prevention efforts should consider these factors.

On the stability of rotational discontinuities and intermediate shocks

International Nuclear Information System (INIS)

Lee, L.C.; Huang, L.; Chao, J.K.

1989-01-01

The stability of rotational discontinuities and intermediate shocks is studied based on a hybrid simulation code. The simulation results show that rotational discontinuities are stable and intermediate shocks are not stationary. Intermediate shocks tend to evolve to rotational discontinuities and waves. The authors employ several different initial profiles for the magnetic field in the transition region and find that the final structure of the discontinuities or shocks is not sensitive to the initial magnetic field profile. The present results are different from those obtained from the resistive MHD simulations. Furthermore, their study indicates that the kinetic effect of particles plays an important role in the structure and stability of rotational discontinuities and intermediate shocks

Full Text Available Introduction: Behavioral interventions for Non Communicable Diseases (NCD abeyance would profit the most, if initiated at an early age. Major risk factors of NCDs are changing life style and behavior pattern which are largely due to practices adopted in younger age. Students' awareness about NCDs and their risk factors is an important part of population based prevention strategy. Objective: To assess the awareness of NCDs and their risk factors among rural intermediate school children. Methodology: A School based cross sectional study was conducted in Chiraigaon Community Development Block of Varanasi from July - Aug 2010. Intermediate school children from eight inter-colleges of Chiraigaon development block were the study subjects. Pretested questionnaire was used in the study and frequency and proportions were used to analyze the data. Results: Less than one third of the children were aware about Diabetes and Hypertension (27% and 31% respectively. Only 18% knew about Body Mass Index (BMI as an indicator of obesity. In general awareness of NCDs was more in boys than girl. Conclusion: Over all awareness of NCDs and their risk factors among students was not satisfactory. There is a need and scope for health education activity regarding NCDs and their risk factors to promote healthy life style among these school children.

Until recently, the economics and financial literature placed little attention on the role that financial intermediation can play in accelerating the rate of economic development in less Developed Countries (LDCs). This has been changed now, however, where some instrumental role has been emphasised for financial intermediation in the process of economic development and growth. It is argued that an expansion of the financial system, size and intermediation in LDCs tends to increase the level o...

Role of oxygen intermediates in UV-induced epidermal cell injury

1984-01-01

To investigate the role of oxygen intermediates (OIs) in sunburn cell (SC) formation and development of UV-inflammation in vivo, groups of mice were injected intravenously with OI scavengers, including bovine blood superoxide dismutase (SOD), bovine liver catalase, L-histidine, D-mannitol, and saline (controls) before and/or after UV irradiation with sunlamp tubes (mainly 280-320 nm; 300 mJ/cm2; UVR). Ear thickness was measured before and 6 and 24 h after UVR. Ears were removed 24 h after UVR and the number of SCs per unit length of ear epidermis was counted using hematoxylineosin stained sections. The number of SCs was significantly decreased (p less than 0.02) by a single injection of SOD (10-30 units/g body weight) given either just before or immediately after (less than 15 min) UVR, while SC formation was no longer suppressed by injections given more than 2 h before or after UVR. Four repeated injections of SOD (10 units/g) also reduced SC counts but did not significantly alter ear-swelling responses (ESR). Neither SC counts nor ESR were remarkably suppressed by 4 injections of any of the other active OI scavengers, inactivated SOD, or bovine serum albumin. A single injection of diethyldithiocarbamate, an SOD inactivator, significantly augmented SC formation (p less than 0.05), but did not change ESR. These findings suggest that OIs generated by UVR participate in SC formation but are not apparently involved in UV-edema

Doctors qualifying from United Kingdom medical schools during the calendar years 1977 and 1983.

Science.gov (United States)

Parkhouse, J; Parkhouse, H F

1989-01-01

At the conclusion of undergraduate medical education in the United Kingdom most students pass a university qualifying examination and obtain a degree in medicine and surgery. Some students pass an external non-university qualifying examination in medicine as an alternative to obtaining a degree, and some do both. The degree may be obtained in the same year as the non-university qualifying examination, or in a different year. Some students from a medical school intake qualify in a later year than expected, for various reasons. Data from university, Health Department and other sources may relate to the academic year, the calendar year, or a fixed date such as 30 September. It is not a simple exercise, therefore, to define the exact number of people who qualify to practise medicine, for the first time, in any given 'year'. In counting qualifiers from individual medical schools, the problems are further compounded by the movement of students between the preclinical and clinical stages of the course, particularly from Oxford and Cambridge to London teaching hospitals. This paper analyses the situation for the calendar years 1977 and 1983, showing a decline in the number of students obtaining double (i.e. both university and non-university) qualifications. The number of UK graduates not registering with the General Medical Council to practise, at least for a time, in the UK was small, and the population base compiled for Medical Career Research Group studies was reasonably accurate in each of the 2 years examined.

Perspective: Spectroscopy and kinetics of small gaseous Criegee intermediates

International Nuclear Information System (INIS)

Lee, Yuan-Pern

2015-01-01

The Criegee intermediates, carbonyl oxides proposed by Criegee in 1949 as key intermediates in the ozonolysis of alkenes, play important roles in many aspects of atmospheric chemistry. Because direct detection of these gaseous intermediates was unavailable until recently, previous understanding of their reactions, derived from indirect experimental evidence, had great uncertainties. Recent laboratory detection of the simplest Criegee intermediate CH 2 OO and some larger members, produced from ultraviolet irradiation of corresponding diiodoalkanes in O 2 , with various methods such as photoionization, ultraviolet absorption, infrared absorption, and microwave spectroscopy opens a new door to improved understanding of the roles of these Criegee intermediates. Their structures and spectral parameters have been characterized; their significant zwitterionic nature is hence confirmed. CH 2 OO, along with other products, has also been detected directly with microwave spectroscopy in gaseous ozonolysis reactions of ethene. The detailed kinetics of the source reaction, CH 2 I + O 2 , which is critical to laboratory studies of CH 2 OO, are now understood satisfactorily. The kinetic investigations using direct detection identified some important atmospheric reactions, including reactions with NO 2 , SO 2 , water dimer, carboxylic acids, and carbonyl compounds. Efforts toward the characterization of larger Criegee intermediates and the investigation of related reactions are in progress. Some reactions of CH 3 CHOO are found to depend on conformation. This perspective examines progress toward the direct spectral characterization of Criegee intermediates and investigations of the associated reaction kinetics, and indicates some unresolved problems and prospective challenges for this exciting field of research

Heat Transfer and Entropy Generation Analysis of an Intermediate Heat Exchanger in ADS

Science.gov (United States)

Wang, Yongwei; Huai, Xiulan

2018-04-01

The intermediate heat exchanger for enhancement heat transfer is the important equipment in the usage of nuclear energy. In the present work, heat transfer and entropy generation of an intermediate heat exchanger (IHX) in the accelerator driven subcritical system (ADS) are investigated experimentally. The variation of entropy generation number with performance parameters of the IHX is analyzed, and effects of inlet conditions of the IHX on entropy generation number and heat transfer are discussed. Compared with the results at two working conditions of the constant mass flow rates of liquid lead-bismuth eutectic (LBE) and helium gas, the total pumping power all tends to reduce with the decreasing entropy generation number, but the variations of the effectiveness, number of transfer units and thermal capacity rate ratio are inconsistent, and need to analyze respectively. With the increasing inlet mass flow rate or LBE inlet temperature, the entropy generation number increases and the heat transfer is enhanced, while the opposite trend occurs with the increasing helium gas inlet temperature. The further study is necessary for obtaining the optimized operation parameters of the IHX to minimize entropy generation and enhance heat transfer.

Intermediate-Mass Black Holes

Miller, M. Coleman; Colbert, E. J. M.

2004-01-01

The mathematical simplicity of black holes, combined with their links to some of the most energetic events in the universe, means that black holes are key objects for fundamental physics and astrophysics. Until recently, it was generally believed that black holes in nature appear in two broad mass ranges: stellar-mass (M~3 20 M⊙), which are produced by the core collapse of massive stars, and supermassive (M~106 1010 M⊙), which are found in the centers of galaxies and are produced by a still uncertain combination of processes. In the last few years, however, evidence has accumulated for an intermediate-mass class of black holes, with M~102 104 M⊙. If such objects exist they have important implications for the dynamics of stellar clusters, the formation of supermassive black holes, and the production and detection of gravitational waves. We review the evidence for intermediate-mass black holes and discuss future observational and theoretical work that will help clarify numerous outstanding questions about these objects.

STUTTERING THERAPY FOR A CHILD AT INTERMEDIATE STUTTERING LEVEL

Full Text Available Stuttering therapy very often demands combination of various approaches or its modification. The main purpose of this study was to present an integrated approach to stuttering modification therapy and fluency shaping therapy for an intermediate school-age male stutterer (11 years old.The therapy for the child lasted for 12 months, sessions have been carried out twice a week, each session lasted for 45 minutes. The child still attends the therapy. The therapy uses integration of stuttering modification therapy and fluency shaping therapy. For the purpose of the fluency shaping therapy, delayed auditory feedback program is applied. During the stuttering modification therapy the child has been taught how to stutter more easily which implies prolongation of all sounds in words on which child stutters, with easy and soft transition from one sound to another. It is continuously being worked with the child on reducing negative feelings and attitudes as well as elimination of avoidance of words and speaking situations. We explained to the parents the treatment program and their role in the program realization. We also explained the possible causes of stuttering, and tried to identify and reduce fluency distractors, and engage the child in as many situations as possible which improved speech fluency.After the application of this program the child has improved fluency during the conversation in clinical and nonclinical conditions (environment. This fluency consists of spontaneous and controlled fluency. Furthermore, fear of speaking and avoidance of speech situations are significantly reduced. On the basis of the applied therapy on the child at intermediate stuttering level it can be concluded that it is possible to integrate successfully both approaches: stuttering modification therapy and fluency shaping therapy.

We report a case of infective endocarditis (IE) caused by ceftaroline-resistant, daptomycin-tolerant, and heterogeneous vancomycin-intermediate methicillin-resistant S. aureus (MRSA). Resistance to ceftaroline emerged in the absence of drug exposure, and the E447K substitution in the active site of PBP2a previously associated with ceftaroline resistance was identified. Additionally, we present evidence of patient-to-patient transmission of the strain within the same unit. This case illustrates the difficulties in treating MRSA IE in the setting of a multidrug-resistant phenotype. Copyright © 2017 American Society for Microbiology.

Full Text Available The goal of this study was to identify the prevalence and correlates of suicidal thinking among Palestinian middle school students by using complex samples analysis to explore data about suicidal ideation and suicidal planning in the past year from 14,303 students in grades 7, 8, and 9 (roughly ages 13–15 years who participated in the Global School-based Student Health Survey (GSHS in 2010 in the Occupied Palestinian Territory (OPT and United Nations Relief and Works Agency (UNRWA refugee camps. We also analyzed data from the seven other GSHS-participating countries from the Eastern Mediterranean region: Iraq, Jordan, Kuwait, Lebanon, Morocco, Tunisia, and the United Arab Emirates. The overall prevalence of suicidal ideation and/or planning was 25.6%. Males were more likely than females to report suicidal thinking. The health behaviors and exposures most strongly associated with suicidal thinking were marijuana use, having no close friends, tobacco use, loneliness, worry-induced insomnia, food insecurity, and being the victim of a bully. Being involved in physical fights and attacks, skipping school, and perceptions of limited parental support were also associated with suicidal thinking. The prevalence of suicidal thinking among Palestinian adolescents was higher than the rates in the other GSHS-participating countries, pointing toward a need for improved access to adolescent mental health services.

Projecting non-diffracting waves with intermediate-plane holography.

Science.gov (United States)

Mondal, Argha; Yevick, Aaron; Blackburn, Lauren C; Kanellakopoulos, Nikitas; Grier, David G

2018-02-19

We introduce intermediate-plane holography, which substantially improves the ability of holographic trapping systems to project propagation-invariant modes of light using phase-only diffractive optical elements. Translating the mode-forming hologram to an intermediate plane in the optical train can reduce the need to encode amplitude variations in the field, and therefore complements well-established techniques for encoding complex-valued transfer functions into phase-only holograms. Compared to standard holographic trapping implementations, intermediate-plane holograms greatly improve diffraction efficiency and mode purity of propagation-invariant modes, and so increase their useful non-diffracting range. We demonstrate this technique through experimental realizations of accelerating modes and long-range tractor beams.

Current accelerator-driven and other intermediate energy technologies require accurate nuclear data to model the performance of the target/blanket assembly, neutron production, activation, heating and damage. In a previous WPEC subgroup, SG13 on intermediate energy nuclear data, various aspects of intermediate energy data, such as nuclear data needs, experiments, model calculations and file formatting issues were investigated and categorized to come to a joint evaluation effort. The successor of SG13, SG14 on the processing and validation of intermediate energy evaluated data files, goes one step further. The nuclear data files that have been created with the aforementioned information need to be processed and validated in order to be applicable in realistic intermediate energy simulations. We emphasize that the work of SG14 excludes the 0-20 MeV data part of the neutron evaluations, which is supposed to be covered elsewhere. This final report contains the following sections: section 2: a survey of the data files above 20 MeV that have been considered for validation in SG14; section 3: a summary of the review of the 150 MeV intermediate energy data files for ENDF/B-VI and, more briefly, the other libraries; section 4: validation of the data library against an integral experiment with MCNPX; section 5: conclusions.

An improved intermediate resonance method for heterogeneous media

International Nuclear Information System (INIS)

Chiovato, O.; Corno, S.; Pasquantonio, F.Di.

1977-01-01

A new formulation is described of the Intermediate Resonance method which incorporates the previous developments suitably modified and improved, together with some new contributions. The 'intermediate' character is directly introduced in the integral operator K, allowing a more rigorous deduction of the equations for evaluating the intermediate parameters related to the nuclides involved in the system. There is no limit to the number of internal (admixed in the fuel) and external moderators. The capability to take into account the interference scattering has been extended to heterogeneous systems. The Doppler broadening is described by means of new accurate rational approximations to the broadened line shape psi. Finally the use of energy mean values suitably defined refines the values of the resonance integrals and resonance absorption cross sections. The Intermediate Resonance method so extended and improved, has been coded in a group of FORTRAN routines, which have been inserted as a calculation option in the fast section of the GGC code for the evaluation of multigroup cross sections. A series of calculations has been carried out, using these routines, and comparisons have been made with Monte Carlo and Nordheim's methods. The results obtained show that the Intermediate Resonance method developed in the present work offers considerable advantages over Nordheim's method: better accuracy in evaluating resonance absorption cross sections, and much smaller computing times.

Full Text Available In recent times, the traditional interaction structures of English both language classrooms and roles of teachers and students are gradually changing. This marks the shift from the teacher-centered classrooms to student-centered classrooms; moving towards ‘student-centered learning’ and‘collaborative working modes’. The contemporary educational world views teachers and students as communicators. In such situations students get more opportunity to ‘participate’, ‘observe’, ‘reflect on’ and ‘practice social ways’. These opportunities expose the students to a more ‘meaning-making’ and ‘knowledge construction processes’. The shift from traditional teaching and learning process to the contemporary one has posed great challenges for teachers, who are always working under pressure to complete the syllabus designed for the academic year. In such a situation it is very important to ascertain if this idea of student-centered classroom is present in the recent classroom. Educationally oriented research into classroom interaction makes it essential for further studies into the classroom interaction in the modern classroom. Hence, this study aims to observe the interaction process that takes place in English classrooms of four government schools in Hilla (Centre of Babylon Governorate. This paper also suggests measures to improve classroom interaction and language learning in the English classes. The main findings from the study are as follows: (a the classroom interaction is teacher-centered, (b teachers partially facilitate learning, the classrooms are controlled by teachers (c the ratio of the teacher-talk is more than student-talk."

Michigan Science Teaching and Assessment Reform (Mi-STAR) is developing an NGSS-aligned integrated science middle school curriculum and associated teacher professional learning program that addresses all performance expectations for the 6-8 grade-band. The Mi-STAR instructional model is a unit- and lesson-level model that scaffolds students in using science practices to investigate scientific phenomena and apply engineering principles to address a real-world challenge. Mi-STAR has developed an 8th grade unit on climate change based on the Mi-STAR instructional model and NGSS performance expectations. The unit was developed in collaboration with Michigan teachers, climate scientists, and curriculum developers. The unit puts students in the role of advisers to local officials who need an evidence-based explanation of climate change and recommendations about community-based actions to address it. Students discover puzzling signs of global climate change, ask questions about these signs, and engage in a series of investigations using simulations and real data to develop scientific models for the mechanisms of climate change. Students use their models as the basis for evidence-based arguments about the causes and impacts of climate change and employ engineering practices to propose local actions in their community to address climate change. Dedicated professional learning supports teachers before and during implementation of the unit. Before implementing the unit, all teachers complete an online self-paced "unit primer" during which they assume the role of their students as they are introduced to the unit challenge. During this experience, teachers experience science as a practice by using real data and simulations to develop a model of the causes of climate change, just as their students will later do. During unit implementation, teachers are part of a professional learning community led by a teacher facilitator in their local area or school. This professional learning

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

Souza, Kevin H; Kamin, Carol; O'Sullivan, Patricia; Moses, Anna; Heestand, Diane

2008-07-01

To examine the organizational structure of educational technology units within U.S. and Canadian medical schools in order to (1) identify organization models that support educational technology, (2) describe key attributes of these models, and (3) discuss the strengths and challenges associated with these models. The authors distributed a survey to 88 schools that had previously provided information on their educational technology services and infrastructure. The authors developed the survey through a series of pilots and, then, from the data for each respondent school, created concept maps, which were used to identify organizational models. The authors conducted analyses to determine differences among models. The authors coded the comments about organizational models and identified themes. The authors received adequate data for analysis from 61 schools (69%). Four models for educational technology organizations emerged: (1) centralized units located in the school of medicine, (2) centralized units located at the health science center, (3) centralized units at the comprehensive university, and (4) no centralized unit (Dispersed Model). The majority (75%) of schools relied on some type of centralized organization. Whereas few organization attributes proved to be statistically significant, the centralized models have more resources devoted to educational technology and a closer alignment with the academic mission than the Dispersed Model. Medical schools primarily use central models. The authors recommend that schools structuring their educational technology resources consider exploration of a central model because of its focused use of resources to improve teaching and learning.

The use of Khat leaves (Catha edulis) in Jazan, southwest of KSA, is prevalent among all segments of the population. This study was conducted to assess the prevalence and predictors of Khat chewing among intermediate and secondary school students of Jazan region. A cross-sectional survey was conducted in late 2011 in Jazan region. A random sample of 3923 students was selected from 72 intermediate and upper secondary schools representing the different educational sectors of the region. A structured self-administered questionnaire was used for data collection. Descriptive statistics, a chi-squared test and logistic regression were performed to examine the prevalence, associations and predictors of Khat chewing. The overall Khat chewing prevalence among students was 20.5% (95% C.I.: 19.27-21.79). The prevalence was significantly higher among males, at 33.1% (95% CI: 31.16-35.08), than among females 4.3% (95% C.I.: 3.39-5.31) ( P academic performance, friends' smoking and Khat chewing, and students' smoking status were associated with a significantly high risk of Khat chewing ( P peer influence, and cigarette smoking. Intervention programs are needed to create awareness among school students and to reduce the prevalence of the habit and its unfavorable consequences.

Kim, Chan Soo; Hong, Sung Deok; Kim, Yong Wan; Chang, Jongh Wa

2009-01-01

Nuclear Hydrogen Development and Demonstration (NHDD) system is a Very High Temperature gascooled Reactor (VHTR) coupled with hydrogen production systems. Intermediate heat exchanger transfers heat from the nuclear reactor to the hydrogen production system. This study presented the sensitivity analysis on a preliminary thermal sizing of the intermediate heat exchanger. Printed Circuit Heat Exchanger (PCHE) was selected for the thermal sizing because the printed circuit heat exchanger has the largest compactness among the heat exchanger types. The analysis was performed to estimate the effect of key parameters including the operating condition of the intermediate system, the geometrical factors of the PCHE, and the working fluid of the intermediate system.

The intermediate mass distribution of the dual resonance pomeron is determined at the one-loop level and it is shown that the mass distribution obtained is remarkably similar to a suitably defined mass distribution in the dual multiperipheral model. Thus it is suggestive to identify the intermediate states of the dual resonance pomeron with multiperipheral processes. (Auth.)

CONDITIONING OF INTERMEDIATE-LEVEL WASTE AT FORSCHUNGSZENTRUM JUELICH GMBH

International Nuclear Information System (INIS)

Krumbach, H.

2003-01-01

This contribution to the group of low-level, intermediate, mixed and hazardous waste describes the conditioning of intermediate-level mixed waste (dose rate above 10 mSv/h at the surface) from Research Centre Juelich (FZJ). Conditioning of the waste by supercompaction is performed at Research Centre Karlsruhe (FZK). The waste described is radioactive waste arising from research at Juelich. This waste includes specimens and objects from irradiation experiments in the research reactors Merlin (FRJ-1) and Dido (FRJ-2) at FZJ. In principle, radioactive waste at Forschungszentrum Juelich GmbH is differentiated by the surface dose rate at the waste package. Up to a surface dose rate of 10 mSv/h, the waste is regarded as low-level. The radioactive waste described here has a surface dose rate above 10 mSv/h. Waste up to 10 mSv/h is conditioned at the Juelich site according to different conditioning methods. The intermediate-level waste can only be conditioned by supercompaction in the processing facility for intermediate-level waste from plant operation at Research Centre Karlsruhe. Research Centre Juelich also uses this waste cell to condition its intermediate-level waste from plant operation

Supersymmetry and intermediate symmetry breaking in SO(10) superunification

International Nuclear Information System (INIS)

Asatryan, H.M.; Ioannisyan, A.N.

1985-01-01

A scheme of simultaneous breakdown of intermediate symmetry SO(10) → SU(3)sub(c) x U(1) x SU(2)sub(L) x SU(2)sub(R) and supersymmetry by means of a single scale parameter is suggested. This intermediate symmetry, which is preferable physically, owing to the broken supersymmetry has a minimum lying lower than SU(4) x SU(2)sub(L) x SU(2)sub(R). The intermediate symmetry is broken by the vacuum expectation value of the Higgs superfields. Owing to the quantum corrections the potential minimum turns out to correspond to breakdown of the intermediate symmetry up to the standard group SU(3)sub(c) x SU(2)sub(L) x U(1)sub(y). The value of the Weinberg angle is less than that in the supersymmetric SU(5) model and agrees with the experiment

Utilization of cold neutron beams at intermediate flux reactors

International Nuclear Information System (INIS)

Clark, D.D.

1992-01-01

With the advent of cold neutron beam (CNB) facilities at U.S. reactors [National Institute of Standards and Technology (NIST) in 1991; Cornell University and the University of Texas at Austin, anticipated in 1992], it is appropriate to reexamine the types of research for which they are likely to be best suited or uniquely suited. With the exception of a small-angle neutron scattering facility at Brookhaven National Laboratory, there has been no prior experience in the United States with such beams, but they have been extensively used at European reactors where cold neutron sources and neutron guides were developed some years age. This paper does not discuss specialized cases such as ultracold neutrons or very high flux facilities such as the Institute Laue-Langevin ractor and the proposed advanced neutron source. Instead, it concentrates on potential utilization of CNBs at intermediate-flux reactors such as at Cornell and Texas, i.e., in the 1-MW range and operated <24 h a day

HIV/AIDS has emerged as the single most formidable challenge to public health. School children of today are exposed to the risk of HIV/AIDS. The study was conducted to determine the knowledge among secondary school students regarding HIV/AIDS and provide suggestions for HIV/AIDS education in schools. A cross-sectional study was conducted among students of tenth to twelfth standard in the intermediate schools of Lucknow, India, from July to October 2011. A total of 215 students, both boys and girls, were enrolled in the study. In this study, for majority of the students (85%), the source of information about HIV/AIDS was the television. Regarding knowledge about modes of transmission of HIV/AIDS among girl students, 95.1% of them told that it is through unprotected sex. A total of 75.8% students said that it was transmitted from mother to child. It was observed that the knowledge of the school students was quite satisfactory for most of the variables like modes of transmission, including mother-to-child transmission of the disease. However, schools should come forward to design awareness campaigns for the benefit of the students.

2017-12-08

Deep well injection and disposal of treated wastewater into the highly transmissive saline Boulder Zone in the lower part of the Floridan aquifer system began in 1971. The zone of injection is a highly transmissive hydrogeologic unit, the Boulder Zone, in the lower part of the Floridan aquifer system. Since the 1990s, however, treated wastewater injection into the Boulder Zone in southeastern Florida has been detected at three treated wastewater injection utilities in the brackish upper part of the Floridan aquifer system designated for potential use as drinking water. At a time when usage of the Boulder Zone for treated wastewater disposal is increasing and the utilization of the upper part of the Floridan aquifer system for drinking water is intensifying, there is an urgency to understand the nature of cross-formational fluid flow and identify possible fluid pathways from the lower to upper zones of the Floridan aquifer system. To better understand the hydrogeologic controls on groundwater movement through the Floridan aquifer system in southeastern Florida, the U.S. Geological Survey and the Broward County Environmental Planning and Community Resilience Division conducted a 3.5-year cooperative study from July 2012 to December 2015. The study characterizes the sequence stratigraphy, seismic stratigraphy, and seismic structures of the lower part of the intermediate confining unit aquifer and most of the Floridan aquifer system.Data obtained to meet the study objective include 80 miles of high-resolution, two-dimensional (2D), seismic-reflection profiles acquired from canals in eastern Broward County. These profiles have been used to characterize the sequence stratigraphy, seismic stratigraphy, and seismic structures in a 425-square-mile study area. Horizon mapping of the seismic-reflection profiles and additional data collection from well logs and cores or cuttings from 44 wells were focused on construction of three-dimensional (3D) visualizations of eight

2014-12-01

Full Text Available OBJECTIVE To analyze the methodology used for assessing the spatial distribution of specialized cardiac care units. METHODS A modeling and simulation method was adopted for the practical application of cardiac care service in the state of Santa Catarina, Southern Brazil, using the p-median model. As the state is divided into 21 health care regions, a methodology which suggests an arrangement of eight intermediate cardiac care units was analyzed, comparing the results obtained using data from 1996 and 2012. RESULTS Results obtained using data from 2012 indicated significant changes in the state, particularly in relation to the increased population density in the coastal regions. The current study provided a satisfactory response, indicated by the homogeneity of the results regarding the location of the intermediate cardiac care units and their respective regional administrations, thereby decreasing the average distance traveled by users to health care units, located in higher population density areas. The validity of the model was corroborated through the analysis of the allocation of the median vertices proposed in 1996 and 2012. CONCLUSIONS The current spatial distribution of specialized cardiac care units is more homogeneous and reflects the demographic changes that have occurred in the state over the last 17 years. The comparison between the two simulations and the current configuration showed the validity of the proposed model as an aid in decision making for system expansion.

The Influence of Scale on School Performance

Directory of Open Access Journals (Sweden)

Robert Bickel

2000-05-01

Full Text Available In this study, we investigate the joint influence of school and district size on school performance among schools with eighth grades (n=367 and schools with eleventh grades in Georgia (n=298. Schools are the unit of analysis in this study because schools are increasingly the unit on which states fix the responsibility to be accountable. The methodology further develops investigations along the line of evidence suggesting that the influence of size is contingent on socioeconomic status (SES. All previous studies have used a single-level regression model (i.e., schools or districts. This study confronts the issue of cross-level interaction of SES and size (i.e., schools and districts with a single-equation-relative-effects model to interpret the joint influence of school and district size on school performance (i.e., the dependent variable is a school-level variable. It also tests the equity of school-level outcomes jointly by school and district size. Georgia was chosen for study because previous single-level analysis there had revealed no influence of district size on performance (measured at the district level. Findings from this study show substantial cross-level influences of school and district size at the 8th grade, and weaker influences at the 11th grade. The equity effects, however, are strong at both grade levels and show a distinctive pattern of size interactions. Results are interpreted to draw implications for a "structuralist" view of school and district restructuring, with particular concern for schooling to serve impoverished communities. The authors argue the importance of a notion of "scaling" in the system of schooling, advocating the particular need to create smaller districts as well as smaller schools as a route to both school excellence and equity of school outcomes.

Addressing Student Burnout: What Medical Schools Can Learn From Business Schools.

Science.gov (United States)

Pathipati, Akhilesh S; Cassel, Christine K

2018-03-13

Although they enter school with enthusiasm for a career in medicine, medical students in the United States subsequently report high levels of burnout and disillusionment. As medical school leaders consider how to address this problem, they can look to business schools as one source of inspiration. In this Commentary, the authors argue-based on their collective experience in both medical and business education-that medical schools can draw three lessons from business schools that can help reinvigorate students. First, medical schools should offer more opportunities and dedicated time for creative work. Engaging with diverse challenges promotes intellectual curiosity and can help students maintain perspective. Second, schools should provide more explicit training in resiliency and the management of stressful situations. Many business programs include formal training in how to cope with conflict and how to make high-stakes decisions whereas medical students are typically expected to learn those skills on the job. Finally, medical schools should provide better guidance on practical career considerations like income, lifestyle, and financial skills. Whether in medicine or business, students benefit from open discussions about their personal and professional goals. Medical schools must ensure students have an outlet for those conversations.

We study the intermediate inflation in a non-canonical scalar field framework with a power-like Lagrangian. We show that in contrast with the standard canonical intermediate inflation, our non-canonical model is compatible with the observational results of Planck 2015. Also, we estimate the equilateral non-Gaussianity parameter which is in well agreement with the prediction of Planck 2015. Then, we obtain an approximation for the energy scale at the initial time of inflation and show that it can be of order of the Planck energy scale, i.e. M{sub P} ∼ 10{sup 18}GeV. We will see that after a short period of time, inflation enters in the slow-roll regime that its energy scale is of order M{sub P}/100 ∼ 10{sup 16}GeV and the horizon exit takes place in this energy scale. We also examine an idea in our non-canonical model to overcome the central drawback of intermediate inflation which is the fact that inflation never ends. We solve this problem without disturbing significantly the nature of the intermediate inflation until the time of horizon exit.

Estimation of intermediate grade uranium resources. Final report

The purpose of this project is to analyze the technique currently used by DOE to estimate intermediate grade uranium (0.01 to 0.05% U 3 O 8 ) and, if possible, suggest alternatives to improve the accuracy and precision of the estimate. There are three principal conclusions resulting from this study. They relate to the quantity, distribution and sampling of intermediate grade uranium. While the results of this study must be validated further, they indicate that DOE may be underestimating intermediate level reserves by 20 to 30%. Plots of grade of U 3 O 8 versus tonnage of ore and tonnage U 3 O 8 indicate grade-tonnage relationships that are essentially log-linear, at least down to 0.01% U 3 O 8 . Though this is not an unexpected finding, it may provide a technique for reducing the uncertainty of intermediate grade endowment. The results of this study indicate that a much lower drill hole density is necessary for DOE to estimate uranium resources than for a mining company to calculate ore resources. Though errors in local estimates will occur, they will tend to cancel over the entire deposit

Policy Variation among Japan, Korea, England and the United States

Directory of Open Access Journals (Sweden)

2001-04-01

Full Text Available School reform initiatives during the last two decades in Japan, Korea, England, and the United States can be understood as balancing acts. Because policymakers in England and the United States saw their school systems fragmented and student outcomes mediocre, they focused reform efforts on raising educational standards, tightening curriculum and assessment, and improving academic achievement. In contrast, policymakers in Japan and Korea, who saw their school systems overstandardized and educational processes deficient, focused their reform efforts on deregulating schools, diversifying curriculum and assessment, and enhancing whole-person education. While school reform policies were formulated and adopted in response to each country’s unique problems, they also were driven by globalization forces that fostered an international perspective. If implemented successfully, such cross-cultural policy variations (i.e., standardization vs. differentiation in curriculum, unification vs. diversification in assessment, and privatization vs. democratization in governance would make distinctive educational systems more alike. Cultural and institutional barriers to educational convergence between the Eastern and Western school systems are discussed.

Structure of replicating intermediates of human herpesvirus type 6

2003-01-01

We have studied the structure of the replicative intermediates of human herpesvirus 6 (HHV-6) using pulsed-field gel electrophoresis, partial digestion, two-dimensional gel electrophoresis, and sedimentation centrifugation. The results show that DNA replication of HHV-6 produces head-to-tail concatemeric intermediates as well as approximately equal amounts of circular monomers or oligomers. Unlike the situation in herpes simplex virus, the intermediates of human herpesvirus 6 replication are not highly branched, suggesting a difference in the mechanism of replication or a lower frequency of homologous recombination in human herpesvirus 6 compared to herpes simplex virus

Suicide is a leading cause of death among school-aged children younger than 12 years but little is known about the epidemiology of suicide in this age group. To describe trends in suicide among US children younger than 12 years by sociodemographic group and method of death. Period trend analysis of national mortality data on suicide in children aged 5 to 11 years in the United States from January 1, 1993, to December 31, 2012. Data were analyzed per 5-year periods, between 1993 to 1997 and 2008 to 2012. Number of suicide deaths and crude suicide rates. Period trends in rates of suicide were estimated using negative binomial regression incidence rate ratios (IRRs). The overall suicide rate among children aged 5 to 11 years remained stable between 1993 to 1997 and 2008 to 2012 (from 1.18 to 1.09 per 1 million; IRR = 0.96; 95% CI, 0.90-1.03). However, the suicide rate increased significantly in black children (from 1.36 to 2.54 per 1 million; IRR = 1.27; 95% CI, 1.11-1.45) and decreased in white children (from 1.14 to 0.77 per 1 million; IRR = 0.86; 95% CI, 0.79-0.94). The overall firearm suicide rate (IRR = 0.69; 95% CI, 0.57-0.85) and firearm suicide rate among white boys (IRR = 0.72; 95% CI, 0.59-0.88) decreased significantly during the study. The rate of suicide by hanging/suffocation increased significantly in black boys (IRR = 1.35; 95% CI, 1.14-1.61), although the overall change in suicide rates by hanging/suffocation or other suicide methods did not change during the study. The stable overall suicide rate in school-aged children in the United States during 20 years of study obscured a significant increase in suicide incidence in black children and a significant decrease in suicide incidence among white children. Findings highlight a potential racial disparity that warrants attention. Further studies are needed to monitor these emerging trends and identify risk, protective, and precipitating factors relevant to suicide prevention efforts

Mechanisms of deterioration of intermediate moisture food systems

Labuza, T. P.

1972-01-01

A study of shelf stability in intermediate moisture foods was made. Major efforts were made to control lipid oxidation and nonenzymatic browning. In order to determine means of preventing these reactions, model systems were developed having the same water activity content relationship of intermediate moisture foods. Models were based on a cellulose-lipid and protein-lipid system with glycerol added as the humectant. Experiments with both systems indicate that lipid oxidation is promoted significantly in the intermediate moisture range. The effect appeared to be related to increased mobility of either reactants or catalysts, since when the amount of water in the system reached a level where capillary condensation occurred and thus free water was present, the rates of oxidation increased. With added glycerol, which is water soluble and thus increases the amount of mobile phase, the increase in oxidation rate occurs at a lower relative humidity. The rates of oxidation were maximized at 61% RH and decreased again at 75% RH probably due to dilution. No significant non-enzymatic browning occurred in the protein-lipid systems. Prevention of oxidation by the use of metal chelating agents was enhanced in the cellulose system, whereas, with protein present, the lipid soluble chain terminating antioxidants (such as BHA) worked equally as well. Preliminary studies of foods adjusted to the intermediate moisture range bear out the results of oxidation in model systems. It can be concluded that for most fat containing intermediate moisture foods, rancidity will be the reaction most limiting stability.
