The cohort method identifies the year the student entered high school for the first time…
Full Text Available The article presents the structure of personal features of students decided to devote their life to medical profession, their personal readiness for a profession of a doctor. 241 students going to enter the Saratov Medical University in 2013 serve as an object of research. Methods of research included psychology tests on a self-assessment of a mental state, ability to empathy, a motivation orientation. Result. It was revealed that the majority of respondents low level of uneasiness, low level of frustration, the average level of aggression, the average level of a rigidity, and also high rates on an empathy scale. The types of the personality in relation to work are emotive and intuitive. Prevalence of motive of achievement of success or motive of avoiding of failures directly depends on specifics of a situation. Conclusion. Students possess qualities which are necessary in professional activity for doctors, namely high resistance to stress, absence of fear before difficulties, low level of rigidity, high level of empathy, the average level of aggression. Students are motivated on success, in situations when they are fully confident.

In Ontario massage therapy is a regulated health profession, and it has been speculated that massage therapy students are motivated primarily by altruistic values, as has been documented in medicine. Students at Sutherland-Chan School and Teaching Clinic in Ontario were surveyed regarding their motivation to enter massage therapy education, with the intention of assessing the influence of certain value complexes on their decision. The results indicate that their decision was influenced more strongly by intrinsic values related to helping and working with people than by the prospect of extrinsic rewards (p < 0.0005). This supports a belief commonly held within the professional community, and bodies well for the future of massage therapy as a caring profession.

A diagnostic test administered at the start of a class should test basic concepts which are recognized as course prerequisites. The questions should not be over-packaged: e.g. students should be required to create models, rather than this being done for them each time. Students should be allowed great latitude in their answers, so we can discover what they are thinking. When administered at the end of a class the goals should be similar: testing concepts taught in the class itself and the retention of necessary concepts from previous classes. Great care has to be taken to avoid teaching to the test. In assessing an entire program, for example an undergraduate majors degree in physics, then one looks for very general skills and knowledge not specific to any one course. The purpose of an undergraduate degree in physics (or indeed any science) is to equip the students with a set of problem-solving skills and basic knowledge which can be applied in a large variety of workplace settings and to allow that student to contribute to civic society as a science-literate person. The creator of any diagnostic test should always have these big goals in mind. We have developed a set of questions which we think fulfill these criteria, yet are not specific to any particular level of science education. They have been administered to students in secondary schools across Canada, incoming first-year science students and final-year physics students at the University of British Columbia. The results will be presented.

The aim of this scoping literature review was to identify the factors related to nursing students' readiness to enter working life. The literature search was carried out in autumn 2017 in PubMed and CINAHL databases. The studies selected for this review (n = 17) were analyzed thematically with inductive content analysis. Four subthemes that were combined into two main factors related to nursing students' readiness to enter working life were found. The main factors found were 1) educational factors and 2) personal factors. Educational factors consisted of professional competence and clinical practice, while personal factors consisted of nursing students' background and feelings. Some nursing students tend to feel insecure about entering working life as a newly graduated nurse. This literature review also supports the importance of clinical practice periods in nursing education and for readiness for working life. Nurse education needs to ensure clinical practice periods which support nursing students' professional growth. Further research is needed on how the factors related to nursing students' readiness to enter working life correlate with each other. Particularly, the association between competence, readiness and positive feelings towards graduation needs further investigation. Copyright © 2018 Elsevier Ltd. All rights reserved.
Full Text Available Dental education aims to produce competent graduates with the ability to provide quality care to the patients and facilitate the smooth integration into professional practice. The objective of this study was to explore the overall preparedness of graduands for integrating into professional practice. The survey was tested for reliability and analysed the career paths, learning preferences, overall knowledge, and confidence amongst graduating dentists in integrating and managing a dental practice on graduation. Sixty-nine students (89.6% in age group of 20–50 years participated in the study. Students indicated a high level of confidence in their skills and ability to work in a team in a practice or collaboratively with other colleagues and specialists but expressed some reservation on their practice management skills (73.1%. Challenges in gaining employment and pressures to repay educational debts are amongst the reasons for graduands preferring a paid job immediately on graduation regardless of demographics. Students indicated that an increase in speciality training and clinical/outreach placements could enhance employability. This study explores the students’ perception of their confidences, knowledge, learning preferences, and practice management skills as a method of evaluating their preparedness to practice on graduation and provides a base line for curriculum structuring to prepare graduands to enter the competitive dental work force.

This research examines the influence of parents on students' studying the STEM disciplines and entering STEM careers. Cases of two graduate students (one female, one male) and one undergraduate student (male) are featured. The first two students in the convenience sample are biology and physics majors in a STEM teacher education programme; the third is enrolled in computer science. The narrative inquiry research method is used to elucidate the students' academic trajectories. Incidents of circumstantial and planned parent curriculum making surfaced when the data was serially interpreted. Other themes included: (1) relationships between (student) learners and (teacher) parents, (2) invitations to inquiry, (3) modes of inquiry, (4) the improbability of certainty, and (5) changed narratives = changed lives. While policy briefs provide sweeping statements about parents' positive effects on their children, narrative inquiries such as this one illuminate parents' inquiry moves within home environments. These actions became retrospectively revealed in their adult children's lived narratives. Nurtured by their mothers and/or fathers, students enter STEM disciplines and STEM-related careers through multiple pathways in addition to the anticipated pipeline.

In this observational study, we aimed to see whether transition in Saudi students entering university life could be a breeding stage for cardiometabolic risk factor emergence and clustering. A total of 1878 apparently healthy Saudi students of the Preparatory Year, King Saud University, Riyadh, KSA (1112 men and 766 women) spanning 2 academic years were included. They were divided into 2 groups based on the validated perceived stress test (PST). Anthropometrics were obtained and fasting blood samples were collected for measurement of fasting blood glucose and a lipid profile. PST score (>27) considered indicative of stress was noted in 44.4% of students. The prevalence of this score was higher in women than in men (49.7% versus 40.7%). The prevalence of obesity, hypertension and dyslipidemia was significantly higher in men than women (p students entering universities. This study sheds light on the social responsibility of universities in promoting a healthy lifestyle, particularly in this age group, when exposure to different kinds of stressors may result in body weight and metabolic changes.

The aim of this study was to explore the motivations of student nurses enrolled in nursing courses across a variety of Pacific Island countries. The image of nursing, the desire to help others, family and friends in the profession, personal experience, security, travel opportunities and flexibility have all been identified as motivators for people to enter nursing. To date, what motivates students in Pacific Island countries to enrol in a nursing course has not been investigated. An exploratory qualitative approach using focus group interviews with 152 nursing students was undertaken. Data were analysed using thematic content analysis, revealing four themes: (i) helping others; (ii) 'making a difference for my people'; (iii) following in the footsteps of others; and (iv) financial and professional gain. In a time of health and nursing workforce shortages, developing a deeper understanding of what drives people can be used to improve recruitment strategies in the future. © 2013 Wiley Publishing Asia Pty Ltd.
Full Text Available Affective answers play an essential role in the process of teaching-learning mathematics. Within this field, the more studied construct in the last three decades is the attitude towards mathematics. This construct have been frequently related to gender differences between the students population as well as the students´ election of mathematics courses and university degrees depending on the level of mathematics that they present. For this reason, we have analyzed, using an adaptation of the Fennema-Sherman Mathematics Attitude Scales (1976, the attitudes towards mathematics of the students who enter the University of Granada, in a global way and classifying the subjects by gender and by the fields of knowledge of their degrees.

Full Text Available For languages other than English there is a lack of empirical evidence about the cognitive profile of students entering higher education with a diagnosis of dyslexia. To obtain such evidence, we compared a group of 100 Dutch-speaking students diagnosed with dyslexia with a control group of 100 students without learning disabilities. Our study showed selective deficits in reading and writing (effect sizes for accuracy between d = 1 and d = 2, arithmetic (d≈1, and phonological processing (d>0.7. Except for spelling, these deficits were larger for speed related measures than for accuracy related measures. Students with dyslexia also performed slightly inferior on the KAIT tests of crystallized intelligence, due to the retrieval of verbal information from long-term memory. No significant differences were observed in the KAIT tests of fluid intelligence. The profile we obtained agrees with a recent meta-analysis of English findings suggesting that it generalizes to all alphabetic languages. Implications for special arrangements for students with dyslexia in higher education are outlined.

Enteral administration of immune-modulating nutrients (eg, glutamine, omega-3 fatty acids, selenium, and antioxidants) has been suggested to reduce infections and improve recovery from critical illness. However, controversy exists on the use of immune-modulating enteral nutrition, reflected by lack of consensus in guidelines. To determine whether high-protein enteral nutrition enriched with immune-modulating nutrients (IMHP) reduces the incidence of infections compared with standard high-protein enteral nutrition (HP) in mechanically ventilated critically ill patients. The MetaPlus study, a randomized, double-blind, multicenter trial, was conducted from February 2010 through April 2012 including a 6-month follow-up period in 14 intensive care units (ICUs) in the Netherlands, Germany, France, and Belgium. A total of 301 adult patients who were expected to be ventilated for more than 72 hours and to require enteral nutrition for more than 72 hours were randomized to the IMHP (n = 152) or HP (n = 149) group and included in an intention-to-treat analysis, performed for the total population as well as predefined medical, surgical, and trauma subpopulations. High-protein enteral nutrition enriched with immune-modulating nutrients vs standard high-protein enteral nutrition, initiated within 48 hours of ICU admission and continued during the ICU stay for a maximum of 28 days. The primary outcome measure was incidence of new infections according to the Centers for Disease Control and Prevention (CDC) definitions. Secondary end points included mortality, Sequential Organ Failure Assessment (SOFA) scores, mechanical ventilation duration, ICU and hospital lengths of stay, and subtypes of infections according CDC definitions. There were no statistically significant differences in incidence of new infections between the groups: 53% (95% CI, 44%-61%) in the IMHP group vs 52% (95% CI, 44%-61%) in the HP group (P = .96). No statistically significant differences were

Full Text Available Parenthood is a process of promoting the child’s progressive development and achieving personal autonomy. Social, family and psychological factors of formation of parental attitudes of the person at the stage of entering adulthood are considered. The mechanisms of the parental family influence on parental attitudes are analyzed. Parenting and children raising are recognized by modern young students as a significant family value with priority of professional and social activity. The revealed gender differences prove a higher assessment of the importance of parenthood and the upbringing of children among males rather than females, who have strongly prioritize their professional careers as compared to parenthood. Young women’s expectations of difficulties in the future of family life are related to child birth and upbringing. The experience of emotional relations in one’s own parent family is proved to determine the importance of parenting for young adults. Positive expectations of student youth regarding future family life and a certain underestimation of the difficulties of the transitional periods of the family life cycle are revealed. The greatest difficulties are predicted by students in connection with the period of child expectation and the first year of child life. The beginning of parental function realization, child raising, economic and household functioning of the family and mutual adaptation of the spouses are listed as the most difficulties in family life cycle. Family factors that determine expectations about difficulties and subjective satisfaction with family life include gender, experience of romantic partnership, full or incomplete family in origin, chronological age.

In this prospective study we wanted to determine whether perceived stress over time among students in the Preparatory Year of King Saud University (KSU) predisposes them to cardiometabolic abnormalities. A total of 110 apparently healthy Saudi students (35 men and 75 women enrolled during the 2010-2011 academic year) were included. Perceived stress was determined at baseline and 1 year later. Anthropometrics were obtained and morning fasting serum glucose, lipid profile and cortisol were measured at both times. Perceived stress was noted among 48.2% of subjects at baseline and was not significantly different after follow-up, with 45.4% scoring high. In men, the prevalence of perceived stress was 48.6% at baseline (13 out of 35) and 37.1% at follow-up (13 out of 35), while in women it was 48% at baseline and 49.3% at follow-up. Interestingly, significant improvements in the blood pressure and lipid profiles, with the exception of HDL-cholesterol, were observed in both men and women, while fasting glucose also improved in women. Serum cortisol was inversely associated to fasting glucose, and total- and LDL-cholesterol (p-values 0.007, 0.04 and 0.04, respectively). These data are opposite to findings in students entering Western universities, in whom increasing stress and a deteriorating cardiometabolic profile have been repeatedly noted. Perceived stress and morning cortisol levels among students of the Preparatory Year in KSU remained constant for both genders over time, yet an improved cardiometabolic profile was observed, suggesting good adaptation among our pre-college students in their first year of university life.

Factors distinguishing osteopathic physicians from their allopathic counterparts include the use of osteopathic manipulative treatment (OMT), application of osteopathic principles and practice (OPP), and a greater likelihood of entering primary care, specifically family medicine (FM). In the United States, the percentage of entering osteopathic medical students who were female rose from 14.3% in fall 1977 to 44.3% in fall 2015. To investigate the perspectives of female osteopathic medical students as they relate to osteopathic distinctiveness. Students at the West Virginia School of Osteopathic Medicine who were eligible to participate in graduation exercises in 2014 or 2015 were asked to complete the school's standard Exit Survey. The research team chose 5 items from the survey to include in the current analysis. Sex had been self-identified at admission, and residency in first postgraduate year was categorized as FM or other specialty. Graduates entering a transitional year or traditional internship were removed from analysis. Analysis was conducted for 308 of the 375 students (82%) expected to graduate in 2014 or 2015. χ2 analysis found no difference by sex in the number of graduates entering FM residencies vs other specialties (P=.727). Statistically significant differences were found in 2 survey items: "Use of OMT will enhance my practice" (P=.005) and "What emphasis do you believe OMT will have in your practice?" (P<.001). Graduating female students responded more favorably to OMT on both items. For the latter item, 91.4% of female and 80.3% of male students indicated OMT would have at least some role in their practices. Sex differences remained after statistically controlling for entry into FM. Female graduating osteopathic medical students were more likely to report that OMT will have at least some role in their practices. Future studies of the attitudes and practice patterns of osteopathic physicians should analyze for differences by sex.
Full Text Available At universities, educating students on real-life practices is one of the key drivers in a changing academic environment. Academic institutions encourage the study of the learning environment and ensure that appropriate strategies are in place for educating students. A first-year Accounting I student stated the importance of computerised accounting: ‘Computerised accounting is used in the workplace and therefore using it in varsity, grants students a view on how things will be after completion of their respective degrees.’ Accordingly, the purpose of this study was to empirically investigate the perceived acquisition of information technology (IT knowledge and determine the skills required for students to convert the knowledge gained into actions as a learning curve for accounting students entering the business world. The results indicated that students’ knowledge of Accounting I increased with the integration of computerised Accounting in the Accounting I Curriculum.

We calculate the heating power of the neutral beam injection (NBI) in the = 4.8% high-beta discharge achieved in the Large Helical Device (LHD). We investigate the difference of the heating efficiency and the heating power profile between with and without the re-entering fast ion effects. When the re-entering fast ion effects are taken into account, the heating efficiency in the co injection of the NBI (co-NBI case) is improved and it is about 1.8 times larger than that without the re-entering effects. In contrast, the heating efficiency with the re-entering effects in the counter injection of the NBI (ctr-NBI case) rarely differs from that without the re-entering ones. We also study the re-entering fast ion effects on the transport properties in the LHD high beta discharges. It is found that the tendency of the thermal conductivities on the beta value is not so much sensitive with and without the re-entering effects. In addition, we investigate the difference in the re-entering fast ion effects caused by the field strength and the magnetic configuration. In the co-NBI case, the re-entering fast ion effects on the heating efficiency increases with the decrease of the field strength. In the contrast, the re-entering fast ion effects in the ctr-NBI case rarely differs by changing the field strength. (author)

Prior interventions to address declining interest in surgical careers have focused on creating early exposure and fostering mentorship at the preclinical medical student level. Navigating the surgical environment can be challenging, however, and preclinical students may be more likely to pursue a surgical career if they are given the tools to function optimally. We designed a 10-wk technical and nontechnical skills curriculum to provide preclinical students with knowledge and skills necessary to successfully navigate the surgical learning environment, followed by placement in high-fidelity surgical simulations and scrubbing in on operative cases with attending surgeons. We administered pre-post surveys to assess student confidence levels in operative skills, self-perceptions of having a mentor, overall course efficacy, and interest in a career in surgery. The overall response rates presurvey and postsurvey were 100% (30 of 30) and 93.3% (28 of 30), respectively. Confidence levels across all operative skills increased significantly after completing the course. Faculty mentorship increased significantly from 30.0% before to 61.5% after the course. Overall effectiveness of the course was 4.00 of 5 (4 = "very effective"), and although insignificant, overall interest in a career in surgery increased at the completion of the course from 3.77 (standard deviation = 1.01) to 4.17 (standard deviation = 0.94). Our curriculum was effective in teaching the skills necessary to enjoy positive experiences in planned early exposure and mentorship activities. Further study is warranted to determine if this intervention leads to an increase in students who formally commit to a career in surgery. Copyright © 2017 Elsevier Inc. All rights reserved.

Full Text Available Abstract Background Behavioral factors contribute importantly to morbidity and mortality, and physicians are trusted sources for information on reducing associated risks. Unfortunately, many clinical encounters do not include prevention counseling, and medical school curriculum plays an important role in training and promoting such counseling among medical students. Methods We surveyed all 93 freshman medical students at entry to the University of California, Davis School of Medicine in 2009 to evaluate baseline knowledge of population health principles and examine their approach to clinical situations involving four common behavioral risk factors illustrated in brief clinical vignettes: smoking, alcohol use in a patient with indications of alcoholism, diet and exercise in an overweight sedentary patient, and a 16-year-old contemplating initiation of sexual intercourse. Based on vignette responses, we assessed willingness to (1 provide information on risks, (2 recommend elimination of the behavior as the most efficacious means for reducing risk, (3 include strategies apart from elimination of the behavior for lowering risk (i.e., harm reduction, and (4 assure of their intention to continue care whether or not recommendations are accepted. Results Students answered correctly 71.4 % (median; interquartile range 66.7 % - 85.7 % of clinical prevention and population health knowledge questions; men scored higher than women (median 83.3 % vs. 66.7 %, p Conclusion Students showed high willingness to educate and respect patient autonomy. There was high willingness to recommend elimination of risk behaviors for smoking, alcohol, and poor diet/exercise, but not for sexual intercourse in an adolescent considering sexual debut. Further research should address promoting appropriate science-based preventive health messages, and curriculum should include explicit discussion of content of recommendations.

Samples collected in 2008 and 2009, from 49 turkey flocks of 6 to 43 days in age and presenting clinical signs of enteric disease and high mortality, were tested by polymerase chain reaction and reverse transcription-polymerase chain reaction for the presence of viruses currently associated with enteric disease (ED) syndromes: astrovirus, reovirus, rotavirus, coronavirus, adenovirus, and parvovirus. Turkey astroviruses were found in 83.67% of the cases and turkey astrovirus 2 (TAst-2) in 26.53%. The investigations directly demonstrated the high prevalence of turkey parvovirus (TuPV) in 23 flocks (46.9%) experiencing signs of ED, making this pathogen the second most identified after astroviruses. Phylogenetic analysis on a 527 base pair-long region from the NS1 gene revealed two main clusters, a chicken parvovirus (ChPV) and a TuPV group, but also the presence of a divergent branch of tentatively named "TuPV-like ChPV" strains. The 23 Hungarian TuPV strains were separately positioned in two groups from the American origin sequences in the TuPV cluster. An Avail-based restriction fragment length polymorphism assay has also been developed for the quick differentiation of TuPV, ChPV, and divergent TuPV-like ChPV strains. As most detected enteric viruses have been directly demonstrated in healthy turkey flocks as well, the epidemiology of this disease complex remains unclear, suggesting that a certain combination of pathogens, environmental factors, or both are necessary for the development of clinical signs.

Methane accounts for roughly 20% of the global radiative climate forcing in the last two and a half centuries. Methane emissions arise from a number of anthropogenic and biogenic sources. In some areas enteric fermentation in livestock produces over 90% of agricultural methane. In the spring of 2013, as a part of the Short Lived Climate Forcer-Mexico field campaign, the Aerodyne Mobile Laboratory in partnership with the Molina Center for the Environment studied methane production associated with enteric fermentation in the rumen of cattle. A variety of different breeds and stocks being raised in two agricultural and veterinary research facilities located in different areas of Mexico were examined. Methane fluxes were quantified using two methods: 1) an atmospherically stable gaseous tracer release was collocated with small herds in a pasture, allowing tracer ratio flux measurements; 2) respiratory CO2 was measured in tandem with methane in the breath of individual animals allowing methane production to be related to metabolism. The use of an extensive suite of very high time response instruments allows for differentiation of individual methane producing rumination events and respiratory CO2 from possible background interferences. The results of these studies will be presented and compared to data from traditional chamber experiments.

Little is known about the physical health, lifestyle beliefs and behaviors, and mental health among first-year health professional graduate students. Therefore, the purpose of this study was to describe these attributes as well as to explore the relationships among them. A descriptive correlational study was conducted on the baseline data from a wellness onboarding intervention study with 93 health sciences students from seven different colleges within a large public land grant university in the Midwest United States. Nearly 40% of the sample was overweight/obese, and 19% of students had elevated total cholesterol levels. Only 44% met the recommended 30 min of exercise 5 days per week. Forty-one percent reported elevated depressive symptoms and 28% had elevated anxiety. Four students reported suicidal ideation. Inverse relationships existed among depression/anxiety and healthy lifestyle beliefs/behaviors. Students entering health professional schools are at high risk for depression, anxiety, and unhealthy behaviors, which could be averted through screening and early evidence-based interventions. Assessing the physical health, lifestyle behaviors, and mental health of first-year health sciences professional students is important to identify health problems and modifiable at-risk behaviors so that early interventions can be implemented to improve outcomes. ©2016 American Association of Nurse Practitioners.

Extensive research exists on female, African American, and Hispanic students pursuing Science, Technology, Engineering and Mathematics (STEM) field disciplines. However, little research evaluates students with disabilities and career decision-making relating to STEM field disciplines. This study explored the career decision-making experiences and self-efficacy for students with disabilities. The purpose of this research study was to document experiences and perceptions of students with disabilities who pursue, and may consider pursuing, careers in the STEM field disciplines by exploring the career decision-making self-efficacy of students with disabilities. This study documented the level of influence that the students with disabilities had or may not have had encountered from parents, friends, advisors, counselors, and instructors as they managed their decision-making choice relating to their academic major/career in the STEM or non-STEM field disciplines. A total of 85 respondents of approximately 340 students with disabilities at one Midwestern public university completed a quantitatively designed survey instrument. The Career Decision-Making Self-Efficacy Scale-Short Form by Betz and Hackett was the instrument used, and additional questions were included in the survey. Data analysis included descriptive statistics and analysis of variance. Based upon the results, college students with disabilities are not currently being influenced by individuals and groups of individuals to pursue the STEM field disciplines. This is a cohort of individuals who can be marketed to increase enrollment in STEM programs at academic institutions. This research further found that gender differences at the institution under study did not affect the career decision-making self-efficacy scores. The men did not score any higher in confidence in career decision-making than the women. Disability type did not significantly affect the relationship between the Career Decision-Making Self

Necrotic enteritis (NE) challenge and high dietary sodium (from sodium chloride) level on odor flux from broiler litter was investigated using 160 day-old Ross 308 male chicks randomly assigned to 4 dietary treatments with 4 replicates of 10 birds each. A 2 × 2 factorial arrangement of treatments was employed. Factors were: presence or absence of NE challenge and normal (1.6 g/kg) or high (4.0 g/kg) dietary sodium (Na) level. On d 20, odorants were collected from litter headspace with a flux hood and measured using selected ion flow tube mass spectrometry (SIFT-MS). On d 33, while challenge did not lead to higher mortality, it reduced feed intake by 5.48% (P litter moisture and litter headspace concentrations of dimethyl sulfide (P litter moisture (P litter headspace concentration of sulfur compounds and phenol (P litter flux of some additional odorants, which included 2,3-butanedione (P broiler farms. © 2017 Poultry Science Association Inc.

Waterborne infections have been shown to be important in outbreaks of gastroenteritis throughout the world. Although improved sanitary conditions are being progressively applied, fecal contaminations remain an emerging problem also in developed countries. The aim of our study was to investigate the prevalence of fecal contaminated water sources in Slovenia, including surface waters and groundwater sources throughout the country. In total, 152 water samples were investigated, of which 72 samples represents groundwater from individual wells, 17 samples from public collection supplies and 63 samples from surface stream waters. Two liters of untreated water samples were collected and concentrated by the adsorption/elution technique with positively charged filters followed by an additional ultracentrifugation step. Group A rotaviruses, noroviruses (genogroups I and II) and astroviruses were detected with real-time RT-PCR method in 69 (45.4%) out of 152 samples collected, of which 31/89 (34.8%) drinking water and 38/63 (60.3%) surface water samples were positive for at least one virus tested. In 30.3% of drinking water samples group A rotaviruses were detected (27/89), followed by noroviruses GI (2.2%; 2/89) and astroviruses (2.2%; 2/89). In drinking groundwater samples group A rotaviruses were detected in 27 out of 72 tested samples (37.5%), genogroup I noroviruses in two (2.8%), and human astroviruses in one (1.4%) samples. In surface water samples norovirus genogroup GII was the most frequently detected (41.3%; 26/63), followed by norovirus GI (33.3%; 21/63), human astrovirus (27.0%; 17/63) and group A rotavirus (17.5%; 11/63). Our study demonstrates relatively high percentage of groundwater contamination in Slovenia and, suggests that raw groundwater used as individual drinking water supply may constitute a possible source of enteric virus infections. In the future, testing for enteric viruses should be applied for drinking water sources in waterborne outbreaks

Full Text Available Introduction: Having awareness, interest, and positive attitude toward one's fields of study leads to the development of a compatibility between demands and expectations on the one hand and future career on the other hand. This study was carried out to determine the level of awareness, attitude, and interest of medicine, dentistry, and pharmacy students of Islamic Azad University, Tehran Medical Sciences Branch toward their own field of study on entering university. Materials and Methods: This research is a basic descriptive study conducted on 273 students who had just entered university. This study was performed using census. Data collection instrument was a four-part questionnaire which included demographic information, and questions measuring students' awareness, attitude, and interest. Results: With regard to their field of study, there was no statistically significant difference in the average of students' awareness (P = 0.731. The attitude of medicine students was significantly more positive than pharmacy and dentistry students (P < 0.001, and the attitude of dentistry students was significantly more positive than that of pharmacy students (P = 0.460. Medical students' interest level was significantly higher than that of pharmacy and dentistry students (P < 0.05, and the interest level of dentistry students was significantly greater than the interest level of pharmacy students (P = 024/0. There was a statistically significant positive relationship between awareness and attitude and between awareness and interest in all of the study subjects (P < 0.001. Conclusion: The study results indicated that having a high level of awareness toward one's major led students studying in medicine, dentistry, and pharmacy to experience a more positive attitude and a higher level of interest. Thus, before entering the university, academic counseling will be beneficial for acquiring a better understanding of most majors, a goal which could be provided

Failures of teamwork and interpersonal communication have been cited as a major patient safety issue. Although healthcare is increasingly being provided in interdisciplinary teams, medical school curricula have traditionally not explicitly included the specific knowledge, skills, attitudes, and behaviors required to function effectively as part of such teams. As part of a new "Foundations" core course for beginning medical students that provided a two-week introduction to the most important themes in modern healthcare, a multidisciplinary team, in collaboration with the Center for Experiential Learning and Assessment, was asked to create an experiential introduction to teamwork and interpersonal communication. We designed and implemented a novel, all-day course to teach second-week medical students basic teamwork and interpersonal principles and skills using immersive simulation methods. Students' anonymous comprehensive course evaluations were collected at the end of the day. Through four years of iterative refinement based on students' course evaluations, faculty reflection, and debriefing, the course changed and matured. Four hundred twenty evaluations were collected. Course evaluations were positive with almost all questions having means and medians greater than 5 out of 7 across all 4 years. Sequential year comparisons were of greatest interest for examining the effects of year-to-year curricular improvements. Differences were not detected among any of the course evaluation questions between 2007 and 2008 except that more students in 2008 felt that the course further developed their "Decision Making Abilities" (OR 1.69, 95% CI 1.07-2.67). With extensive changes to the syllabus and debriefer selection/assignment, concomitant improvements were observed in these aspects between 2008 and 2009 (OR = 2.11, 95% CI: 1.28-3.50). Substantive improvements in specific exercises also yielded significant improvements in the evaluations of those exercises. This

The enteric nervous system is composed of both enteric neurones and enteric glia. Enteric glial cells were first described by Dogiel and are now known to outnumber neurones approximately 4 : 1. In the past, these cells were assumed to subserve a largely supportive role; however, recent evidence indicates that enteric glial cells may play a more active role in the control of gut function. In transgenic mouse models, where enteric glial cells are selectively ablated, the loss of glia results in intestinal inflammation and disruption of the epithelial barrier. Enteric glia are activated specifically by inflammatory insults and may contribute actively to inflammatory pathology via antigen presentation and cytokine synthesis. Enteric glia also express receptors for neurotransmitters and so may serve as intermediaries in enteric neurotransmission. Thus, enteric glia may serve as a link between the nervous and immune systems of the gut and may also have an important role in maintaining the integrity of the mucosal barrier and in other aspects of intestinal homeostasis.

In the studies reported, evidence has been presented that U.S. students traveling to Mexico represent a model for the study of travelers' diarrhea. The incidence of illness acquisition approximates that published in other studies of travelers. Natural immunity was shown to develop as students remained in Mexico presumably through repeated exposure to prevalent agents, particularly ETEC. ETEC, shigella strains and no detectable agent represented the largest groups when etiologic assessment was made. Food probably served as the important source of diarrhea particularly that due to ETEC and shigella strains. The level of bacteria isolated from food suggested that organism replication occurred due to improper temperature storage rather than to heavy initial contamination. The location of food consumption was related to degree of risk: self preparation was the safest, eating in Mexican homes the least safe and consumption of food in public restaurants was intermediate in risk. Water probably played a role in the transmission of viral infection. The risk of water contamination appeared to be highest during the rainy seasons. Finally, the antimicrobial agents TMP/SMX and TMP alone were shown to effectively prevent and treat this form of travelers' diarrhea.
Full Text Available Blogging has emerged as one of the most popular forms of online discourse. The ease and lack of expense in setting up blogs has raised intriguing possibilities for language learning classrooms. The unique nature of their architecture and their low cost have not only affected how students can publish and distribute their work to a wider audience but also how they see themselves as authors. This paper focuses on the use of blogs in an L2 writing course concentrating on the controversies surrounding plagiarism. Blogs were used as a means of generating ideas for their academic papers and as texts that could be cited in their papers. This paper analyzes the blogs of a Somali immigrant student to explore blogs' relationship to the development of his academic writing. His purposes and strategies for using blogs are discussed both as a way of seeing the variety of writing strategies he developed in his blogs, as well as what his use of blogs could tell his teachers about the strengths and weaknesses of his writing. The paper attempts to improve our understanding of how blogging in L2 composition courses can contribute to the development of a student’s writing.

Full Text Available Abstract Background Mental distress among medical students is often reported. Burnout has not been studied frequently and studies using interviewer-rated diagnoses as outcomes are rarely employed. The objective of this prospective study of medical students was to examine clinically significant psychiatric morbidity and burnout at 3rd year of medical school, considering personality and study conditions measured at 1st year. Methods Questionnaires were sent to 127 first year medical students who were then followed-up at 3rd year of medical school. Eighty-one of 3rd year respondents participated in a diagnostic interview. Personality (HP5-i and Performance-based self-esteem (PBSE-scale were assessed at first year, Study conditions (HESI, Burnout (OLBI, Depression (MDI at 1st and 3rd years. Diagnostic interviews (MINI were used at 3rd year to assess psychiatric morbidity. High and low burnout at 3rd year was defined by cluster analysis. Logistic regressions were used to identify predictors of high burnout and psychiatric morbidity, controlling for gender. Results 98 (77% responded on both occasions, 80 (63% of these were interviewed. High burnout was predicted by Impulsivity trait, Depressive symptoms at 1st year and Financial concerns at 1st year. When controlling for 3rd year study conditions, Impulsivity and concurrent Workload remained. Of the interviewed sample 21 (27% had a psychiatric diagnosis, 6 of whom had sought help. Unadjusted analyses showed that psychiatric morbidity was predicted by high Performance-based self-esteem, Disengagement and Depression at 1st year, only the later remained significant in the adjusted analysis. Conclusion Psychiatric morbidity is common in medical students but few seek help. Burnout has individual as well as environmental explanations and to avoid it, organisational as well as individual interventions may be needed. Early signs of depressive symptoms in medical students may be important to address. Students

Enteric duplications have been described throughout the entire gastrointestinal tract. The usual perinatal presentation is an abdominal mass. Duplications associated with the foregut have associated respiratory symptoms, whereas duplications in the midgut and hindgut can present with obstructive symptoms, perforation, nausea, emesis, hemorrhage, or be asymptomatic, and identified as an incidental finding. These are differentiated from other cystic lesions by the presence of a normal gastrointestinal mucosal epithelium. Enteric duplications are located on the mesenteric side of the native structures and are often singular with tubular or cystic characteristics. Management of enteric duplications often requires operative intervention with preservation of the native blood supply and intestine. These procedures are usually very well tolerated with low morbidity.

ABSTRACT Objective: The main aim of this research is to investigate the prevalence of bullying behaviour, its victims and the types of bullying and places of bullying among 14-17 year-old adolescents in a sample of school children in Bursa, Turkey. Methodology: A cross-sectional survey questionnaire was conducted among class 1 and class 2 high school students for identification bullying. Results: Majority (96.7%) of the students were involved in bullying behaviours as aggressors or victims. For a male student, the likelihood of being involved in violent behaviours was detected to be nearly 8.4 times higher when compared with a female student. Conclusion: a multidisciplinary approach involving affected children, their parents, school personnel, media, non-govermental organizations, and security units is required to achieve an effective approach for the prevention of violence targeting children in schools as victims and/or perpetrators.

Bacteria used as indicators for pathogenic microorganisms in water are not considered adequate as enteric virus indicators. Surface water from a tropical high-altitude system located in Mexico City that receives rainwater, treated and non-treated wastewater used for irrigation, and groundwater used for drinking, was studied. The presence of enterovirus, rotavirus, astrovirus, coliphage, coliform bacteria, and enterococci was determined during annual cycles in 2001 and 2002. Enteric viruses in concentrated water samples were detected by reverse transcriptase-polymerase chain reaction (RT-PCR). Coliphages were detected using the double agar layer method. Bacteria analyses of the water samples were carried out by membrane filtration. The presence of viruses and bacteria in the water used for irrigation showed no relationship between current bacterial indicator detection and viral presence. Coliphages showed strong association with indicator bacteria and enterovirus, but weak association with other enteric viruses. Enterovirus and rotavirus showed significant seasonal differences in water used for irrigation, although this was not clear for astrovirus. Coliphages proved to be adequate faecal pollution indicators for the irrigation water studied. Viral presence in this tropical high-altitude system showed a similar trend to data previously reported for temperate zones.

Since 1850, compressed-air work has been used to prevent shafts or tunnels under construction from flooding. Until the 1980s, workers were digging in compressed-air environments. Since the introduction of tunnel boring machines (TBMs), very little digging under pressure is needed. However, the wearing out of cutter-head tools requires inspection and repair. Compressed-air workers enter the pressurized working chamber only occasionally to perform such repairs. Pressures between 3.5 and 4.5 bar, that stand outside a reasonable range for air breathing, were reached by 2002. Offshore deep diving technology had to be adapted to TBM work. Several sites have used mixed gases: in Japan for deep shaft sinking (4.8 bar), in The Netherlands at Western Scheldt Tunnels (6.9 bar), in Russia for St. Petersburg Metro (5.8 bar) and in the United States at Seattle (5.8 bar). Several tunnel projects are in progress that may involve higher pressures: Hallandsås (Sweden) interventions in heliox saturation up to 13 bar, and Lake Mead (U.S.) interventions to about 12 bar (2010). Research on TBMs and grouting technologies tries to reduce the requirements for hyperbaric works. Adapted international rules, expertise and services for saturation work, shuttles and trained personnel matching industrial requirements are the challenges.

Assessing applicants' personal competencies in the admission process has proven difficult because there is not an agreed-on set of personal competencies for entering medical students. In addition, there are questions about the measurement properties and costs of currently available assessment tools. The Association of American Medical College's Innovation Lab Working Group (ILWG) and Admissions Initiative therefore engaged in a multistep, multiyear process to identify personal competencies important to entering students' success in medical school as well as ways to measure them early in the admission process. To identify core personal competencies, they conducted literature reviews, surveyed U.S and Canadian medical school admission officers, and solicited input from the admission community. To identify tools with the potential to provide data in time for pre-interview screening, they reviewed the higher education and employment literature and evaluated tools' psychometric properties, group differences, risk of coaching/faking, likely applicant and admission officer reactions, costs, and scalability. This process resulted in a list of nine core personal competencies rated by stakeholders as very or extremely important for entering medical students: ethical responsibility to self and others; reliability and dependability; service orientation; social skills; capacity for improvement; resilience and adaptability; cultural competence; oral communication; and teamwork. The ILWG's research suggests that some tools hold promise for assessing personal competencies, but the authors caution that none are perfect for all situations. They recommend that multiple tools be used to evaluate information about applicants' personal competencies in deciding whom to interview.

One of the goals in treating patients with chronic obstructive pulmonary disease (COPD) who suffer from hypoxemia, hypercapnia, and malnutrition is to correct the malnutrition without increasing the respiratory quotient and minimize the production of carbon dioxide. This 3-wk study evaluated the efficacy of feeding a high-fat, low-carbohydrate (CHO) nutritional supplement as opposed to a high-carbohydrate diet in COPD patients on parameters of pulmonary function.S METHODS: Sixty COPD patients with low body weight (diet (15% protein, 20% to 30% fat, and 60% to 70% CHO), or the experimental group, which received two to three cans (237 mL/can) of a high-fat, low-CHO oral supplement (16.7% protein, 55.1% fat, and 28.2% CHO) in the evening as part of the diet. Measurements of lung function (forced expiratory volume in 1 s or volume of air exhaled in 1 s of maximal expiration, minute ventilation, oxygen consumption per unit time, carbon dioxide production in unit time, and respiratory quotient) and blood gases (pH, arterial carbon dioxide tension, and arterial oxygen tension) were taken at baseline and after 3 wk. Lung function measurements decreased significantly and forced expiratory volume increased significantly in the experimental group. This study demonstrates that pulmonary function in COPD patients can be significantly improved with a high-fat, low-CHO oral supplement as compared with the traditional high-CHO diet.

Radiation enteritis with severe complications including intestinal bleeding, fistula, and stenosis were treated surgically in 9 cases. These 9 cases included 7 cases of cancer of the uterine cervix and 2 single cases of seminoma and melanoma. The patients received 60 Co or Linac x-ray external irradiation with or without intracavitary irradiation by a radium needle. Radiation injury began with melena, vaginorectal fistula, and intestinal obstruction 3 to 18 months after irradiation. One patient with melena underwent colostomy and survived 2 years. One of the three patients with vaginorectal fistula who had colostomy survived 1.5 years. In intestinal obstruction, one patients had bypass operation and three patients had resection of the intestine and the other had both. Leakage was noted in one patient, but the others had favorable prognosis. (Ueda, J.)

Today's K-12 students will be the scientists and engineers who bring currently emerging technologies to fruition. Existing research endeavors will be continued and expanded upon in the future only if these students are adequately prepared. High school-university collaborations provide an effective means of recruiting and training the next generation of scientists and engineers. Here, we describe our successful high school-university collaboration in the context of other models. We have developed an authentic inquiry-oriented environmental chemistry research program involving high school students as researchers. The impetus behind the development of this project was twofold. First, participation in authentic research may give some of our students the experience and drive to enter technical studies after high school. One specific goal was to develop a program to recruit underrepresented minorities into university STEM (science, technology, engineering, and mathematics) programs. Second, inquiry-oriented lessons have been shown to be highly effective in developing scientific literacy among the general population of students. This collaboration involves the use of local resources and equipment available to most high schools and could serve as a model for developing high school- university partnerships.

Type 2 diabetic patients may need enteral nutrition support as part of their treatment. The objective was to compare glycemic and lipid control in hospitalized patients with type 2 diabetes requiring feeding via nasogastric tube using enteral feedings with either a highcarbohydrate or a high-monounsaturated-fat content. This trial included type 2 diabetes patients admitted to the hospital for neurologic disorders or head and neck cancer surgery who received either a low-carbohydrate-high-mono-unsaturated-fat (Glucerna) or a high-carbohydrate diet (Precitene Diabet). Glycemic and lipid control was determined weekly. Safety and gastrointestinal tolerance were also assessed. A total of 104 patients were randomized and 63 were evaluable according to preestablished protocol criteria. Median duration of therapy was 13 days in both groups. Mean glucose was significantly increased at 7 days of treatment (p = .006) in the Precitene arm, with no significant variations in the Glucerna arm. Mean weekly blood triglycerides levels in the Precitene arm were increased without reaching statistical significance, whereas patients in the Glucerna arm showed a stable trend. Patients in the Precitene arm showed a significantly higher incidence of diarrhea than patients in Glucerna arm (p = .008), whereas the incidence of nausea was smaller in the Precitene arm than in the Glucerna arm (p = .03). An enteral formula with lower carbohydrate and higher monounsaturated fat (Glucerna) has a neutral effect on glycemic control and lipid metabolism in type 2 diabetic patients compared with a high-carbohydrate and a lower-fat formula (Precitene Diabet).

Full Text Available Enteroparasites are related to gastrointestinal alterations among patients with HIV/AIDS, some causing severe manifestations in the period before the institution of the highly active antiretroviral therapy (HAART. The prevalence of enteroparasitoses in patients with HIV/AIDS seen at two hospitals in Ceará , Brazil, was compared in the pre-HAART (Group 1; n = 482 and HAART (Group 2; n = 100 eras. Fecal parasitologic examinations (FPE were performed using the direct, Lutz, Baermann-Moraes and modified Ziehl-Neelsen methods. The following parasites were detected in Groups 1 and 2, respectively: Strongyloides stercoralis - 30.1% and 11% (p<0.0001, Ascaris lumbricoides - 15.6% and 2% (p<0.0001, hookworms - 13.7% and 2% (p<0.0001, Trichuris trichiura - 13.1% and 1% (p<0.0001, Hymenolepis nana - 0 and 1% (p = 0.1718, Giardia duodenalis - 7.9% and 1% (p = 0.0076, Entamoeba histolytica/dispar - 3.3% and 1% (p = 0.3301, Isospora belli - 4.8% and 1% (p = 0.0993, Cryptosporidium sp. - 8.1% and 0 (p = 0.0007, and non-pathogenic protozoans as well. There was a significant reduction in the prevalence of enteroparasites between the eras (63.9% to 24%; p<0.0001. In the HAART era, the following observations were made: greater frequency of enteroparasites in patients without antiretroviral therapy (p = 0.0575, as in those with AIDS (p = 0.08, and diarrhea (36% of the patients; lack of association with positive FPE (p = 0.626; and non-detection of Cryptosporidium sp. Strongyloides stercoralis showed an elevated prevalence in the two eras and was more frequent in men (32.41% than women (19.04% of Group 1 (p = 0.018, a finding suggesting the transmission of the helminth through sodomy. The advent of the HAART modified the profile of opportunistic infections, including parasites, probably due to the reconstitution of cellular immunity and the direct action of HAART on the parasites.

Foodborne viruses, especially human noroviruses, are recognized as leading causes of nonbacterial gastroenteritis worldwide. Development of effective inactivation methods is of great importance to control their spread. In this study, the effect of high-intensity ultrasound (HIUS) on the infectivity of three foodborne virus surrogates was investigated. The three surrogates, murine norovirus (MNV-1), feline calicivirus (FCV-F9), and MS2 bacteriophage, were diluted in phosphate-buffered saline (PBS) or orange juice to a titer of approximately 6 log(10) PFU/mL or approximately 4 log(10) PFU/mL. The ultrasound treatment was performed in duplicate by immersing the HIUS probe in virus-containing solution that was cooled in ice-water and sonicated at 20 kHz for 2, 5, 10, 15, 20, and 30 min with 30 sec on and 30 sec off. The infectivity of the recovered viruses after each ultrasound treatment was evaluated in duplicate using standardized plaque assays and compared to untreated controls. The results show that HIUS effectiveness depended on the virus type, the initial titer of the viruses, and the virus suspension solution. At titers of approximately 4 log(10) PFU/mL in PBS, feline calicivirus (FCV)-F9, MS2, and murine norovirus (MNV)-1 required 5-, 10-, and 30-min treatment, respectively, for complete inactivation. At initial titers of approximately 4 log(10) PFU/mL in orange juice, FCV-F9 required a 15-min treatment for complete inactivation and only a 1.55 log(10) PFU/mL reduction was achieved for MNV-1 in orange juice after 30-min treatment. Thus, inactivation by HIUS in orange juice was much lower than in PBS. Experiments using titers of approximately 6 log(10) PFU/mL showed decreased effects compared to those using titers of approximately 4 log(10) PFU/mL. These results indicate that HIUS alone is not sufficient to inactivate virus in food. Hurdle technologies that combine HIUS with antimicrobials, heat, or pressure should be explored for viral inactivation.

An alpha slow-moving high-density-lipoprotein (HDL) subfraction was seen in a patient presenting with radiation enteritis and peritoneal carcinosis, who was given long-term cyclic parenteral nutrition. This subfraction, observed in addition to normal HDL, was precipitated with low-density lipoproteins (LDL) and very-low-density lipoproteins (VLDL) by sodium phosphotungstate-magnesium chloride. The patient's serum lipoproteins were analyzed after fractionation by density gradient ultracentrifugation. The alpha slow-moving HDL floated in the ultracentrifugation subfractions with densities ranging from 1.028 to 1.084 kg/L, and their main apolipoproteins included apolipoprotein E in addition to apolipoprotein A-I. These HDL were larger than HDL2. The pathogenesis of this unusual HDL subfraction is hypothesized

Full Text Available Although poor health-related behaviors that impact development of chronic diseases begin much earlier than when actual disease is evident, few studies have examined health behaviors in college students, who may be at an important transitional period where early intervention could prevent development of chronic diseases. The purpose of this study was to examine health-related factors in female college students ( N = 61 by race/ethnicity and weight status. We found significant differences in health profiles between non-Hispanic White (White and African American students, including greater physical fitness and healthier diets among White students. Overweight/obese students had worse health profiles than healthy BMI students. Furthermore, weight status was significantly associated with cardiovascular fitness. This supports a focus on PA promotion for interventions in the period of emerging adulthood, alongside the other healthy behaviors, to elicit improvements in weight status and potential reduction of chronic disease risks.

In the last 8 years, several studies have documented that many adolescents acknowledge having exchanged sexually explicit cell phone pictures of themselves, a behavior termed sexting. Differences across studies in how sexting was defined, recruitment strategies, and cohort have resulted in sometimes significant differences in as basic a metric as what percentage of adolescents have sent, received, or forwarded such sexts. The psychosocial and even legal risks associated with sexting by minors are significantly serious that accurate estimates of its prevalence, including over time, are important to ascertain. In the present study, students (N = 656) from a single private high school were surveyed regarding their participation in sexting. Students at this same school were similarly surveyed four years earlier. In this second survey, reported rates of sending (males 15.8%; females 13.6%) and receiving (males 40.5%; females 30.6%) sexually explicit cell phone pictures (revealing genitals or buttocks of either sex or female breasts) were generally similar to those reported at the same school 4 years earlier. Rates of forwarding sexts (males 12.2%; females 7.6%) were much lower than those previously acknowledged at this school. Correlates of sexting in this study were similar to those reported previously. Overall, our findings suggest that sexting by adolescents (with the exception of forwarding) remains a fairly common behavior, despite its risks.

Launch into education about pharmacology (LEAP) is an inquiry-based science enrichment program designed to enhance competence in biology and chemistry and foster interest in science careers especially among under-represented minorities. The study of how drugs work, how they enter cells, alter body chemistry, and exit the body engages students to conceptualize fundamental precepts in biology, chemistry, and math. Students complete an intensive three-week course in the fundamentals of pharmacology during the summer followed by a mentored research component during the school year. Following a 5E learning paradigm, the summer course captures student interest by introducing controversial topics in pharmacology and provides a framework that guides them to explore topics in greater detail. The 5E learning cycle is recapitulated as students extend their knowledge to design and to test an original research question in pharmacology. LEAP students demonstrated significant gains in biology and chemistry knowledge and interests in pursuing science. Several students earned honors for the presentation of their research in regional and state science fairs. Success of the LEAP model in its initial 2 years argues that coupling college-level coursework of interest to teens with an authentic research experience enhances high school student success in and enthusiasm for science.

Full Text Available This study aims to assess the understanding of the notion of function and the ability to articulate different semiotic registers for representation by new students in the university in Colombia. Immediate context is taken as the Faculty of Engineering at a public university. Epistemologically the study is based on symbolic interaction by analyzing the meanings that students attributed to this mathematical concept when addressing problem solving. The methodology, therefore, is qualitatively and use of theoretical coding is done. For analysis of the results it has been applied grounded theory with a structured approach. The information generated by this study corresponds to a test that showed students two graphic representations with the intent to identify which of them was a function, besides which should argue their response. Altogether 86 arguments around the concept are analyzed. Data analysis was done through atlas.ti 7.0 software. The system allows a glimpse of emerging categories the following findings: conceptual deficiencies, diversity in conceptual approaches, conceptual referents, semiotic representations, and finally highlight the various conceptual variations.

Hepatitis E virus (HEV) is responsible for many enterically transmitted viral hepatitides around the world. It is currently one of the waterborne diseases of global concern. In industrialized countries, HEV appears to be more common than previously thought, even if it is rarely virulent. In Switzerland, seroprevalence studies revealed that HEV is endemic, but no information was available on its environmental spread. The aim of this study was to investigate -using qPCR- the occurrence and concentration of HEV and three other viruses (norovirus genogroup II, human adenovirus-40 and porcine adenovirus) in influents and effluents of 31 wastewater treatment plants (WWTPs) in Switzerland. Low concentrations of HEV were detected in 40 out of 124 WWTP influent samples, showing that HEV is commonly present in this region. The frequency of HEV occurrence was higher in summer than in winter. No HEV was detected in WWTP effluent samples, which indicates a low risk of environmental contamination. HEV occurrence and concentrations were lower than those of norovirus and adenovirus. The autochthonous HEV genotype 3 was found in all positive samples, but a strain of the non-endemic and highly pathogenic HEV genotype I was isolated in one sample, highlighting the possibility of environmental circulation of this genotype. A porcine fecal marker (porcine adenovirus) was not detected in HEV positive samples, indicating that swine are not the direct source of HEV present in wastewater. Further investigations will be necessary to determine the reservoirs and the routes of dissemination of HEV. Copyright © 2013 Elsevier Ltd. All rights reserved.

Young Engineers and Scientists (YES) is a community partnership between Southwest Research Institute (SwRI), and local high schools in San Antonio, Texas (USA) during the past 16 years. The YES program provides talented high school juniors and seniors a bridge between classroom instruction and real world, research experiences in physical sciences (including space science) and engineering. YES consists of two parts: 1) an intensive three-week summer workshop held at SwRI where students experience the research environment first-hand; develop skills and acquire tools for solving scientific problems, attend mini-courses and seminars on electronics, computers and the Internet, careers, science ethics, and other topics; and select individual research projects to be completed during the academic year; and 2) a collegial mentorship where students complete individual research projects under the guidance of their mentors during the academic year and earn honors credit. At the end of the school year, students publicly present and display their work, acknowledging their accomplishments and spreading career awareness to other students and teachers. During these years, YES has developed a website for topics in space science from the perspective of high school students, including NASA's Magnetospheric Multiscale Mission (MMS) (http://yesserver.space.swri.edu). High school science teachers participate in the workshop and develop space-related lessons for classroom presentation in the academic year. Student evaluations indicate the effectiveness of YES on their academic preparation and choice of college majors. Over the past 16 years, all YES graduates have entered college, several have worked for SwRI, one business has started, and three scientific publications have resulted. Acknowledgements. We acknowledge funding and support from the NASA MMS Mission, Texas Space Grant Consortium, Northside Independent School District, SwRI, and several local charitable foundations.

Some schools fall short of the high demand to increase science scores on state exams because low-performing students enter high school unprepared for high school science. Low-performing students are not successful in high school for many reasons. However, using inquiry methods have improved students' understanding of science concepts. The purpose of this qualitative research study was to investigate the teachers' lived experiences with using inquiry methods to motivate low-performing high school science students in an inquiry-based program called Xtreem Science. Fifteen teachers were selected from the Xtreem Science program, a program designed to assist teachers in motivating struggling science students. The research questions involved understanding (a) teachers' experiences in using inquiry methods, (b) challenges teachers face in using inquiry methods, and (c) how teachers describe student's response to inquiry methods. Strategy of data collection and analysis included capturing and understanding the teachers' feelings, perceptions, and attitudes in their lived experience of teaching using inquiry method and their experience in motivating struggling students. Analysis of interview responses revealed teachers had some good experiences with inquiry and expressed that inquiry impacted their teaching style and approach to topics, and students felt that using inquiry methods impacted student learning for the better. Inquiry gave low-performing students opportunities to catch up and learn information that moved them to the next level of science courses. Implications for positive social change include providing teachers and school district leaders with information to help improve performance of the low performing science students.

To determine the effect of enteral fish oil and safflower oil supplementation on the intestinal microbiome in infants with an enterostomy born premature. Infants with an enterostomy born premature were randomized to receive early enteral supplementation with a high-fat polyunsaturated fatty acid (HF-PUFA) blend of fish oil and safflower oil vs standard nutritional therapy. We used 16S rRNA gene sequencing for longitudinal profiling of the microbiome from the time of study entry until bowel reanastomosis. We used weighted gene coexpression network analysis to identify microbial community modules that differed between study groups over time. We performed imputed metagenomic analysis to determine metabolic pathways associated with the microbial genes. Sixteen infants were randomized to receive enteral HF-PUFA supplementation, and 16 infants received standard care. The intestinal microbiota of infants in the treatment group differed from those in the control group, with greater bacterial diversity and lower abundance of Streptococcus, Clostridium, and many pathogenic genera within the Enterobacteriaceae family. We identified 4 microbial community modules with significant differences between groups over time. Imputed metagenomic analysis of the microbial genes revealed metabolic pathways that differed between groups, including metabolism of amino acids, carbohydrates, fatty acids, and secondary bile acid synthesis. Enteral HF-PUFA supplementation was associated with decreased abundance of pathogenic bacteria, greater bacterial diversity, and shifts in the potential metabolic functions of intestinal microbiota.

Current treatment options for chronic hyperkalemia in children with chronic kidney disease include dietary restrictions or enteral sodium polystyrene sulfonate (SPS); however, dietary restrictions may compromise adequate nutrition and enteral SPS may be limited by palatability, adverse effects and feeding tube obstruction. A potentially safer alternative is to pretreat enteral nutrition (EN) with SPS prior to consumption. The purpose of this study was to evaluate the efficacy and safety of pretreating EN with SPS in pediatric patients with hyperkalemia. We performed a retrospective cohort study between September 2012 and May 2016 at the Children's Hospital of Philadelphia. In all, 14 patients (age range 0.5-53.2 months) who received 19 courses of SPS pretreatment of EN were evaluated. Serum electrolytes were evaluated at baseline and within 1 week of initiating therapy. The primary endpoint was mean change in potassium at 7 days. Secondary endpoints included the mean change in serum sodium, chloride, bicarbonate, calcium, phosphorous and magnesium, as well as the percentage of patients who developed electrolyte abnormalities within the first week of treatment. Serum potassium levels decreased from 6.0 to 4.4 mmol/L (P < 0.001) and serum sodium levels increased from 135.8 to 141.3 mmol/L (P = 0.008) 1 week after initiating SPS pretreatment. No significant differences in mean serum calcium or magnesium levels were noted. Nevertheless, more than half of the courses resulted in at least one electrolyte abnormality, with hypokalemia (31.6%), hypernatremia (26.3%) and hypocalcemia (21.1%) occurring most frequently. Pretreatment of EN with SPS is an effective method for treating chronic hyperkalemia in pediatric patients; however, close monitoring of electrolytes is warranted.

Full Text Available Enteric fever, a systemic infection caused by the bacteria Salmonella Typhi and Salmonella Paratyphi A, is endemic in Kathmandu, Nepal. Previous work identified proximity to poor quality water sources as a community-level risk for infection. Here, we sought to examine individual-level risk factors related to hygiene and sanitation to improve our understanding of the epidemiology of enteric fever in this setting.A matched case-control analysis was performed through enrollment of 103 blood culture positive enteric fever patients and 294 afebrile community-based age and gender-matched controls. A detailed questionnaire was administered to both cases and controls and the association between enteric fever infection and potential exposures were examined through conditional logistic regression. Several behavioral practices were identified as protective against infection with enteric fever, including water storage and hygienic habits. Additionally, we found that exposures related to poor water and socioeconomic status are more influential in the risk of infection with S. Typhi, whereas food consumption habits and migration play more of a role in risk of S. Paratyphi A infection.Our work suggests that S. Typhi and S. Paratyphi A follow different routes of infection in this highly endemic setting and that sustained exposure to both serovars probably leads to the development of passive immunity. In the absence of a polyvalent vaccine against S. Typhi and S. Paratyphi A, we advocate better systems for water treatment and storage, improvements in the quality of street food, and vaccination with currently available S. Typhi vaccines.

The result and outcome of the cloud chamber project, which aims to develop a cloud chamber useful for science education is reported in detail. A project includes both three high school students and a teacher as a part of Super Science High School (SSH) program in our school. We develop a dry-ice-free cloud chamber using salt and ice (or snow). Technical details of the chamber are described. We also argue how the project have affected student's cognition, motivation, academic skills and behavior. The research project has taken steps of professional researchers, i.e., in planning research, applying fund, writing a paper and giving a talk in conferences. From interviews with students, we have learnt that such style of scientific activity is very effective in promoting student's motivation for learning science.

Enteral feeding provides physiologic, metabolic, safety, and cost benefits over parenteral nutrition. There are various ways enteral nutritional is administered and scheduled. The method of administration must be individualized to each patient's specific needs. Enteral nutrition is not only the supply of exogenous substrates and to prevent depletion of endogenous sources. Today the enteral nutrition becomes part of a therapeutic strategy to influence the severity of the disease to affect the function of GIT, and to modulate immune responses of the gut and the whole organism. Early enteral nutrition in the postoperative period reduces the risk of infectious complications. (author)

Characteristics of health professions schools, public school systems, and community-based organizations in successful partnerships to increase the numbers of underrepresented minority students entering health professions education.
Carline, Jan D; Patterson, Davis G
To identify characteristics of health professions schools, public schools, and community-based organizations in successful partnerships to increase the number of underrepresented minority students entering health professions. The Robert Wood Johnson Foundation and the W. K. Kellogg Foundation funded the Health Professions Partnership Initiative program developed from Project 3000 by 2000 of the Association of American Medical Colleges. Semi-structured interviews were completed with awardees and representatives of the funding agencies, the national program office, and the national advisory committee between the fall of 2000 and the summer of 2002. Site visits were conducted at ten sites, with representatives of partner institutions, teachers, parents, and children. Characteristics that supported and hindered development of successful partnerships were identified using an iterative qualitative approach. Successful partnerships included professional schools that had a commitment to community service. Successful leaders could work in both cultures of the professional and public schools. Attitudes of respect and listening to the needs of partners were essential. Public school governance supported innovation. Happenstance and convergence of interests played significant roles in partnership development. The most telling statement was "We did it, together." This study identifies characteristics associated with smoothly working partnerships, and barriers to successful program development. Successful partnerships can form the basis on which educational interventions are built. The study is limited by the definition of success used, and its focus on one funded program. The authors were unable to identify outcomes in terms of numbers of children influenced by programs or instances in which lasting changes in health professions schools had occurred.
Full Text Available Access to the higher education system in Mexico has been characterized by educational inequalities explained by social and reproductionist currents. The phenomenon occurs in graduate students with a high school diploma and coming from different contexts (social, cultural, economic, institutional and academic ones that create a process of transition far away from equal opportunities. Therefore, the differences due to cultural diversity do not generate equitable access to higher education institutions. The aim of this study was to identify the social, cultural and academic factors affecting the access to or the abandonment of the academic education of students with expectations of entering the higher education system. The research was based on the results obtained from forty technicians who studied at a vocational high school with high academic performance in Mexico, and were supposed to enter the higher level. It was an exploratory descriptive investigation with qualitative approach, using two multiple-choice item questionnaires whose results were analyzed interpretively. The sampling was non-probability, with the technique of “snowball” and “convenience”. The results showed that the level of parents’ schooling, social relations, and academic career of graduates were decisive to enter the higher education; so it can be concluded that the students’ origin generate inequality in educational achievement.

Full Text Available Introduction: The aim of the study was to assess the level of awareness of smoking and non smoking students on harmful impact of nicotine and cigarette smoke on human body. Material and methods: The study was carried out in March 2011 in high schools in Szczecin. Own elaborated questionnaire was used. 288 students from high school, technical college and vocational school were tested. Results: The majority of responders (95,1% claimed that cigarette smoke is harmful both for passive and active smokers. They most often pinpoint the direct cause connected with smoking to pulmonary diseases (264 persons and cancers (240 persons. Almost 90% of students found negative impact of tobacco products on development of fetus of pregnant women. Overwhelming majority of respondents (83,2% feels anxious if it comes to stay in a room filled with smoke. Conclusions: The awareness of high school students on negative influence of smoking on human body is quite satisfactory, but there is still a need for more education in the range of diseases and symptoms connected with smoking.

The objectives of this study were to evaluate the relationship between residual feed intake (RFI; g/d) and enteric methane (CH) production (g/kg DM) and to compare CH and carbon dioxide (CO) emissions measured using respiration chambers (RC) and the GreenFeed emission monitoring (GEM) system (C-Lock Inc., Rapid City, SD). A total of 98 crossbred replacement heifers were group housed in 2 pens and fed barley silage ad libitum and their individual feed intakes were recorded by 16 automated feeding bunks (GrowSafe, Airdrie, AB, Canada) for a period of 72 d to determine their phenotypic RFI. Heifers were ranked on the basis of phenotypic RFI, and 16 heifers (8 with low RFI and 8 with high RFI) were randomly selected for enteric CH and CO emissions measurement. Enteric CH and CO emissions of individual animals were measured over two 25-d periods using RC (2 d/period) and GEM systems (all days when not in chambers). During gas measurements metabolic BW tended to be greater ( ≤ 0.09) for high-RFI heifers but ADG tended ( = 0.09) to be greater for low-RFI heifers. As expected, high-RFI heifers consumed 6.9% more feed ( = 0.03) compared to their more efficient counterparts (7.1 vs. 6.6 kg DM/d). Average CH emissions were 202 and 222 g/d ( = 0.02) with the GEM system and 156 and 164 g/d ( = 0.40) with RC for the low- and high-RFI heifers, respectively. When adjusted for feed intake, CH yield (g/kg DMI) was similar for high- and low-RFI heifers (GEM: 27.7 and 28.5, = 0.25; RC: 26.5 and 26.5, = 0.99). However, CH yield differed between the 2 measurement techniques only for the high-RFI group ( = 0.01). Estimates of CO yield (g/kg DMI) also differed between the 2 techniques ( ≤ 0.03). Our study found that high- and low-efficiency cattle produce similar CH yield but different daily CH emissions. The 2 measurement techniques differ in estimating CH and CO emissions, partially because of differences in conditions (lower feed intakes of cattle while in chambers, fewer days

Full Text Available Nutritional support of surgical patients is a necessary part of the treatment. It alone cannot cure the disease but it significantly affects the recovery of patients and supports surgical interventions. Patients in malnutrition have shown to have significantly more postoperative infectious and non-infectious complications. This significantly prolongs treatment time and increases costs. However, there is one fact that cannot be expressed in money, which is the patient's impression of the surgical intervention. Adequate preoperative patient support, based on the intake of liquid nutritive solutions, reduces preoperative stress and deflects the metabolic response. Now, it is recommended for adults and children older than one year to drink clear liquid up to 2 hours before induction in anesthesia. Appropriate enteral nutrition has a significant place in the postoperative recovery of patients. Enteral nutrition is reducing complications, mainly infectious complications because the function of the digestive system as one large immune system is preserved. Perioperative enteral nutrition is a necessary part of the modern treatment of surgical patients. In addition to the significant effect on the occurrence of postoperative complications, it is also important that this type of diet improves the psychological status of patients.

Enteric dysbiosis is associated with chronic inflammation and interacts with obesity and insulin resistance. Obesity and diabetes are induced in ICR (Institute of Cancer Research) mice fed a high-fat diet and administered a streptozocin injection. These mice were treated with normal rice (NR), normal rice with a high resistant starch content (NRRS) or Se-rich rice (selenium-enriched rice) with a high resistant starch content (SRRS). Faecal cell counts of Bifidobacterium, Lactobacillus and Enterococcus were significantly higher in SRRS-treated mice than in diabetic controls, while Enterobacter cloacae were lower. Similar results were also found in NRRS-treated mice. In contrast, no significant difference was found between NR-treated and diabetic control groups. The treatments with SRRS and NRRS reduced the faecal pH values of the diabetic mice. Regarding the inflammatory factor levels, lower levels of serum C-reactive protein (CRP), tumour necrosis factor-α (TNF-α), interleukin-6 (IL-6), nuclear factor-k-gene binding (NF-κB) and leptin (LEP) and higher adiponutrin (ADPN) levels were found in the SRRS and NRRS-treated mice compared with the diabetic and NR-treated mice. In addition, the CRP, IL-6 and NF-κB levels in the SRRS-treated mice were significantly reduced compared with those observed in the NRRS-treated mice. The reverse transcription-PCR (RT-PCR) results showed that the SRRS and NRRS-treated mice presented higher expression levels of orphan G protein-coupled receptor 41 (GPR41) and orphan G protein-coupled receptor 43 (GPR43) proteins compared with diabetic mice and NR-treated mice. These results indicate that treatments with rice high in RS exert beneficial effects by improving enteric dysbiosis and chronic inflammation. In addition, selenium and RS may exert synergistic effects on chronic inflammation. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

In nuclear reaction studies a differentiation of the reaction products according to their type and energy is generally required. At right angle of incidence a particle identification method based on the relation between the track diameter and particle energy can be well applied to plastic track detectors of low registration sensitivity. We have tried to extend this 'track-diameter method' to the high-sensitivity CR-39 sheets by selecting special incident angles for particle detection. The utility of such a measuring procedure, called 'track-size method', is presented for alpha and proton spectroscopy. A theory is developed to calculate at arbitrary angles the main parameters affecting the energy resolving power of the 'track-size method', namely the critical layer thickness (which has to be removed from the detector surface for track-induction) and the depth and minor axis of etch-pits.

Science education is taking the teaching of science from a traditional (lecture) approach to a multidimensional sense-making approach which allows teachers to support students by providing exploratory experiences. Using projects is one way of providing students with opportunities to observe and participate in sense-making activity. We created a learning environment that fostered inquiry-based learning. Students were engaged in a variety of Inquiry activities that enabled them to work in cooperative planning teams where respect for each other was encouraged and their ability to grasp, transform and transfer information was enhanced. Summer, 1998: An air pollution workshop was conducted for high school students in the Medgar Evers College/Middle College High School Liberty Partnership Summer Program. Students learned the basics of meteorology: structure and composition of the atmosphere and the processes that cause weather. The highlight of this workshop was the building of hand-held sunphotometers, which measure the intensity of the sunlight striking the Earth. Summer, 1999: high school students conducted a research project which measured the mass and size of ambient particulates and enhanced our ability to observe through land based measurements changes in the optical depth of ambient aerosols over Brooklyn. Students used hand held Sunphotometers to collect data over a two week period and entered it into the NASA GISS database by way of the internet.

The authors taught an educational module developed as part of the EARTHTIME (www.earth-time.org) outreach initiative to 215 high school students from a Massachusetts (USA) High School as part of an "out-of-school" field trip. The workshop focuses on uranium-lead (U-Pb) dating of zircons and its application to solving a geological problem. The theme of our 2.5-hour module is the timing of the K-T boundary and a discussion of how geochronology can be used to evaluate the two main hypotheses for the cause of the concurrent extinction—the Chicxlub impact and the massive eruption of the Deccan Traps. Activities are divided into three parts: In the first part, the instructors lead hands-on activities demonstrating how rock samples are processed to isolate minerals by their physical properties. Students use different techniques, such as magnetic separation, density separation using non-toxic heavy liquids, and mineral identification with a microscope. We cover all the steps from sampling an outcrop to determining a final age. Students also discuss geologic features relevant to the K-T boundary problem and get the chance to examine basalts, impact melts and meteorites. In the second part, we use a curriculum developed for and available on the EARTHTIME website (http://www.earth-time.org/Lesson_Plan.pdf). The curriculum teaches the science behind uranium-lead dating using tables, graphs, and a geochronology kit. In this module, the students start by exploring the concepts of half-life and exponential decay and graphically solving the isotopic decay equation. Manipulating groups of double-sided chips labeled with U and Pb isotopes reinforces the concept that an age determination depends on the Pb/U ratio, not the absolute number of atoms present. Next, the technique's accuracy despite loss of parent and daughter atoms during analysis, as well as the use of isotopic ratios rather than absolute abundances, is explained with an activity on isotope dilution. Here the students

Background Although shopping behavior among adolescents is normal, for some the shopping becomes problematic. An assessment of adolescent shopping behavior along a continuum of severity and its relationship to other behaviors and health issues is incompletely understood. Methods A large sample of high school students (n=3999) was examined using a self-report survey with 153 questions concerning demographic characteristics, shopping behaviors, other health behaviors including substance use, and functioning variables such as grades and violent behavior. Results The overall prevalence of problem shopping was 3.5% (95%CI: 2.93–4.07). Regular smoking, marijuana and other drug use, sadness and hopelessness, and antisocial behaviors (e.g., fighting, carrying weapons) were associated with problem shopping behavior in both boys and girls. Heavy alcohol use was significantly associated with problem shopping only in girls. Conclusion Problem shopping appears fairly common among high school students and is associated with symptoms of depression and a range of potentially addictive and antisocial behaviors. Significant distress and diminished behavioral control suggest that excessive shopping may often have significant associated morbidity. Additional research is needed to develop specific prevention and treatment strategies for adolescents who report problems with shopping. PMID:21497217

The objective of this study was to investigate the effect of 3 soybean sources differing in fatty acid profile and processing method on productivity, milk composition, digestibility, rumen fermentation, and enteric methane emission in lactating dairy cows. The soybean sources were conventional, high-linoleic-acid variety extruded soybean meal (ESBM; 8.7% ether extract with 15% oleic and 54% linoleic acids); extruded Plenish (DuPont Pioneer, Johnston, IA), high-oleic-acid variety soybean meal (EPSBM; 8.4% ether extract with 73% oleic and 8% linoleic acids); and whole, heated Plenish soybeans (WPSB; 20.2% ether extract). The study involved 15 Holstein cows in a replicated 3 × 3 Latin square design experiment with three 28-d periods. The inclusion rate of the soybean sources in the diet was (dry matter basis) 17.1, 17.1, and 7.4% for ESBM, EPSBM, and WPSB, respectively, which resulted in ether extract concentration of the diets of 3.99, 3.94, and 4.18%, respectively. Compared with ESBM, the Plenish diets tended to increase dry matter intake and decreased feed efficiency (but had no effect on energy-corrected milk feed efficiency). The Plenish diets increased milk fat concentration on average by 5.6% and tended to increase milk fat yield, compared with ESBM. The WPSB diet tended to increased milk true protein compared with the extruded soybean meal diets. Treatments had no effect on rumen fermentation and enteric methane or carbon dioxide emissions, except pH was higher for WPSB versus EPSBM. The Plenish diets decreased the prevalence of Ruminococcus and increased that of Eubacterium and Treponema in whole ruminal contents. Total-tract apparent digestibility of organic matter and crude protein were decreased by WPSB compared with ESBM and EPSBM. Compared with the other treatments, urinary N excretion was increased by EPSBM and fecal N excretion was greater for WPSB. Treatments had marked effects on milk fatty acid profile. Generally, the Plenish diets increased mono

Full Text Available Nutrition support for critically ill patients supplemented with additional modular protein may promote skeletal muscle protein anabolism in addition to counteracting acute nitrogen loss. The present study was designed to investigate whether the essential amino acid (EAA enriched high-protein enteral nutrition (EN modulates the insulin-like growth factor-1 (IGF-1 system and activates the mammalian target of rapamycin (mTOR anabolic signaling pathway in a trauma-hemorrhagic shock (T-HS rat model.Male Sprague-Dawley rats (n = 90, 278.18 ± 0.94 g were randomly assigned to 5 groups: (1 normal control, (2 pair-fed, (3 T-HS, (4 T-HS and standard EN, and (5 T-HS and EAA enriched high-protein EN. Six animals from each group were harvested on days 2, 4, and 6 for serum, gastrocnemius, soleus, and extensor digitorum longus sample collection. T-HS significantly reduced muscle mass. Nutrition support maintained muscle mass, especially the EAA enriched high-protein EN. Meanwhile, a pronounced derangement in IGF-1-IGFBPs axis as well as impaired mTOR transduction was observed in the T-HS group. Compared with animals receiving standard EN, those receiving EAA enriched high-protein EN presented 18% higher serum free IGF-1 levels following 3 days of nutrition support and 22% higher after 5 days. These changes were consistent with the concomitant elevation in serum insulin and reduction in corticosterone levels. In addition, phosphorylations of downstream anabolic signaling effectors - including protein kinase B, mTOR, and ribosomal protein S6 kinase1 - increased significantly in rats receiving EAA enriched high-protein EN.Our findings firstly demonstrate the beneficial effect of EAA enriched high-protein EN on the metabolic modulation of skeletal muscle protein anabolism by regulating the IGF-1 system and downstream anabolic signaling transduction.

Historically educators in the United States have used the Stanford-Binet intelligence test to measure a students' ability in logical/mathematical and linguistic domains. This measurement is being used by a society that has evolved from agrarian and industrial-based economies to what is presently labeled a technological society. As society has changed so have the educational needs of the students who will live in this technological society. This study assessed the multiple intelligences of high school students enrolled in theoretical and applied science (physics and applied physics) courses. Studies have verified that performance and outcomes of students enrolled in these courses are similar in standardized testing but instructional methodology and processes are dissimilar. Analysis of multiple intelligence profiles collected from this study found significant differences in logical/mathematical, bodily/kinesthetic and intrapersonal multiple intelligences of students in theoretical science courses compared to students in applied science courses. Those differences clearly illustrate why it is imperative for educators to expand the definition of intelligence for students entering the new millennium.

Over the last several decades, forensic science---the application of science to civil and criminal legal matters---has become of increasing popularity with the public. The range of disciplines within the field is immense, offering individuals the potential for a unique career, regardless of their specific interests or expertise. In response to this growth, many organizations, both public and private, have recognized the need to create forensic science programs that strive to maintain and enhance the quality of forensic science education. Unfortunately, most of the emphasis placed on developing these materials relates to post-secondary education, and creates a significant lack of forensic science educational materials available in the U.S., especially in Oklahoma. The purpose of this project was to create a high school curriculum that provides the foundation for building a broad, yet comprehensive, overview of the field of forensic science and its associated disciplines. The overall goal was to create and provide course materials to high school teachers in order to increase their knowledge of forensic science such that they are able to teach its disciplines effectively and with accuracy. The Forensic Science Curriculum for High School Students includes sample lesson plans, PowerPoint presentations, and lab activities with step-by-step instructions.

Nutritional support plays an important role in the treatment of patients with burns. Due to the severe hypercatabolism that develops in these patients, oral support is insufficient in most cases, and this makes it essential to initiate artificial nutritional support (either enteral or parenteral). Enteral nutrition is more physiological than parenteral, and data exist which show that in patients with burns, enteral nutrition exercises a protective effect on the intestine and may even reduce the hypermetabolic response in these patients. The purpose of the study was to evaluate the effectiveness and tolerance of enteral nutritional support with a hypercaloric, hyperproteic diet with a high content of branched amino acids in the nutritional support of patients suffering from burns. The study included 12 patients (8 males and 4 females), admitted to the Burns Unit. Average age was 35 +/- 17 years (range: 21-85 years). The percentage of body surface affected by the burns was 10% in two cases, between 10-30% in three cases, between 30-50% in five cases and over 50% in two cases. Initiation of the enteral nutrition was between twenty-four hours and seven days after the burn. The patients were kept in the unit until they were discharged, and the average time spent in the unit was 31.5 days (range: 17-63 days). Total energetic requirements were calculated based on Harris-Benedict, with a variable aggression factor depending on the body surface burned, which varied from 2,000 and 4,000 cal day. Nitrogenous balance was determined on a daily basis, and plasmatic levels of total proteins, albumin and prealbumin on a weekly basis. There was a significant difference between the prealbumin values at the initiation and finalization of the enteral nutrition (9.6 +/- 2.24 mg/dl compared with 19.75 +/- 5.48 mg/dl; p diet was very good, and only mild complications such as diarrhoea developed in two patients. Enteral nutrition is a suitable nutritional support method for patients with

In this study, the intestinal endocrine cells were investigated in 13 surgical specimens affected by radiation enteritis. Endocrine cells were studied by means of Grimelius' silver staining and immunostaining for chromogranin, a general marker of endocrine cells. Positively stained cells were quantified by counting their number per unit length of muscularis mucosa. Results in radiation enteritis were compared with matched control specimens by using Student's t test. Chromogranin immunostaining showed a statistically significant increase of endocrine cells in radiation enteritis specimens compared with controls both in small and large intestine (ileum, 67.5 +/- 23.5 cells per unit length of muscularis mucosa in radiation enteritis versus 17.0 +/- 6.1 in controls; colon, 40.9 +/- 13.7 cells per unit length of muscularis mucosa in radiation enteritis versus 9.5 +/- 4.1 in controls--p less than 0.005 in both instances). Increase of endocrine cells was demonstrated also by Grimelius' staining; however, without reaching statistical significance. It is not clear whether or not the increase of endocrine cells in radiation enteritis reported in this study is caused by a hyperplastic response or by a sparing phenomenon. We should consider that increased endocrine cells, when abnormally secreting their products, may be involved in some of the clinical features of radiation enteropathy. In addition, as intestinal endocrine cells produce trophic substances to the intestine, their increase could be responsible for the raised risk of developing carcinoma of the intestine in long standing radiation enteritis

Oral administrations of Eimeria species (d 9 and a field strain of Clostridium perfringens (d 14 were used to induce NE. Broiler performance was analysed at d 13, 23, 30 and 35. Intestinal lesion score and bacterial count were analysed on d 16. The NE challenge reduced overall bird performance and induced severe intestinal lesions, without causing notable mortality. At d 23 bird weight was significantly lower (P < 0.001 in the challenged birds compared with the unchallenged birds, but by d 30 the challenged birds had recovered and challenge no longer had an impact on bird performance. Birds fed the HAA diet had greater body weight by d 35 and heightened Lactobacillus content in the ileum at d 16 (P < 0.05. Birds that were fed the HAA diet after a period of fasting performed better in terms of feed conversion ratio (FCR under challenge. The findings from this study suggest there are beneficial effects of feeding high amino acid diets to birds in response to external stresses, such as post-hatch fasting and subclinical NE.

Electromagnetic induction is an important, yet complex, physics topic that is a part of Croatian high school curriculum. Nine Croatian high school students of different abilities in physics were interviewed using six demonstration experiments from electromagnetism (three of them concerned the topic of electromagnetic induction). Students were asked to observe, describe, and explain the experiments. The analysis of students' explanations indicated the existence of many conceptual and reasoning difficulties with the basic concepts of electromagnetism, and especially with recognizing and explaining the phenomenon of electromagnetic induction. Three student mental models of electromagnetic induction, formed during the interviews, which reoccurred among students, are described and analyzed within the knowledge-in-pieces framework.

Full Text Available This paper presents an investigation on deaf students' interests in spending their leisure times. We design a questionnaire and distribute among all deaf students who are enrolled in high schools in two provinces of Iran. The questionnaire consists of three parts, in the first part, we ask female and male deaf students about their interests in various entertainment activities in Likert scale. In terms of gender, we find out that walking inside or outside house is number one favorite exercise for female students while male students mostly prefer to walk on the streets. Although male students prefer to go biking or running activities, female students prefer to go for picnic or similar activities. This could be due to limitations on female for running or biking inside cities. While going to picnic with members of family or friends is the third popular activity for male students, stretching exercises is third most popular activity among female students. Breathing exercise is the fourth most popular activity among both male and female students. The second part of the survey is associated with the barriers for having no exercise among deaf students. According to our survey, while lack of good attention from public and ordinary people on exercising deaf students is believed to be number one barrier among male students, female students blame lack of transportation facilities as the most important barrier. However, both female and male students believe these two items are the most important factors preventing them to exercise. Lack of awareness for exercising deaf students and lack of good recreational facilities are the third most important barriers among male and female students. The last part of the survey attempted to detect important entertainment activities. Watching TV, entertaining with mobile devices, chatting with friends and watching DVD or movies were the most important items influencing deaf students' free times.DOI: 10.5267/j.msl.2012

Ensuring students graduate high school ready to enter college or the workforce has become a prime focus within secondary education. High school graduates are often ill-prepared for college-level work and often have to register for remedial courses before they can take standard college level courses (Southern Regional Education Board, 2010). Serving as both a solution to this concern and an alternative to traditional high schools, early college high schools were created to focus on increasing the number of students graduating from high school and enrolling in college. Early college high schools seek to serve students who have traditionally underperformed in school and those who are underrepresented in higher education including students of color, first-generation college students, students from low socioeconomic backgrounds, and English language learners (Barnett, Bucceri, Hindo, Kim, 2013; "Overview & FAQS," 2013). In efforts to learn more about how early colleges are meeting the needs of students, this dissertation examines the experiences, identity construction, and perceptions of Black male students at a science, technology, engineering, and mathematics (STEM) based early college high school. Using a qualitative case study design, participants were eight Black male upperclassmen enrolled in a STEM early college high school, located on the campus of a four-year university. Data was collected through focus groups and individual interviews and data was analyzed thematically. Findings suggest students in this study have largely positive experiences at their early college high school. Despite some challenges, the early college high school environment helps facilitate scholar identities, and the STEM focus of the school helps students learn more about their strengths and weaknesses. The implications of the research, recommendations for educational stakeholders, and recommendations for future research are discussed.

Background: Research has primarily concentrated on adults' implicit theories about high quality science education for all students. Little work has considered the students' perspective. This study investigated high school students' implicit theories about what helped them learn science. Purpose: This study addressed (1) What characterizes high school students' implicit theories of what facilitates their learning of science?; (2) With respect to students' self-classifications as African American or European American and female or male, do differences exist in the students' implicit theories? Sample, design and methods: Students in an urban high school located in south-eastern United States were surveyed in 2006 about their thoughts on what helps them learn science. To confirm or disconfirm any differences, data from two different samples were analyzed. Responses of 112 African American and 118 European American students and responses from 297 European American students comprised the data for sample one and two, respectively. Results: Seven categories emerged from the deductive and inductive analyses of data: personal responsibility, learning arrangements, interest and knowledge, communication, student mastery, environmental responsiveness, and instructional strategies. Instructional strategies captured 82% and 80% of the data from sample one and two, respectively; consequently, this category was further subjected to Mann-Whitney statistical analysis at p ethnic differences. Significant differences did not exist for ethnicity but differences between females and males in sample one and sample two emerged. Conclusions: African American and European American students' implicit theories about instructional strategies that facilitated their science learning did not significantly differ but female and male students' implicit theories about instructional strategies that helped them learn science significantly differed. Because students attend and respond to what they think

The southern San Joaquin basin is one of the United States' most prolific oil producing regions but also one facing numerous problems including low high school graduation rates, low college enrollments, high college dropout rates, low wages, and higher than average unemployment. Investment in STEM education experiences for high school students has been emphasized by California State University Bakersfield as a means to improving these metrics with programs such as the Research Experience Vitalizing Science-University Program (REVS-UP). Now in its seventh year, the REVS-UP (funded by Chevron) forms teams of high school students, a high school teacher, a CSUB graduate student, and a CSUB professor to work for four weeks on a research project. For the past two summers student-teacher teams investigated the diagenesis and mineralogy of the Temblor Formation sandstones in the subsurface of the San Joaquin basin oil fields that are potential CO2 sequestration sites. With a graduate student leading the teams in sample preparation and analysis by scanning electron microscope equipped with an energy dispersive x-ray spectrometer (SEM-EDS) and cathode luminescence system (SEM-CL) data was gathered on diagenetic processes, detrital framework grains, and authigenic cements. Typically students are introduced to the project in a series of brief seminars by faculty and are then introduced to the techniques and samples. During the second week the students are usually capable of preparing samples and collecting data independently. The final week is focused on developing student-authored research posters which are independently presented by the students on the final day. This gives high school students the opportunity to learn advanced geologic topics and analytical techniques that they would otherwise not be exposed to as well as to gain research and presentation skills. These types of projects are equally important for the graduate students involved as it allows them the

Full Text Available The objective of this study was to identify profiles of high school students, based on variables related to academic performance, socioeconomic status, cultural capital and family organization. A total of 21,724 high school students, from the five municipalities of the state of Baja California, took part. A K-means cluster analysis was performed to identify the profiles. The analyses identified two clearly-defined clusters: Cluster 1 grouped together students with high academic performance and who achieved higher scores for socioeconomic status, cultural capital and family involvement, whereas Cluster 2 brought together students with low academic achievement, and who also obtained lower scores for socioeconomic status and cultural capital, and had less family involvement. It is concluded that the family variables analyzed form student profiles that can be related to academic achievement.

Statement of the problem. Few studies in biology education have examined the underlying presuppositions which guide thinking and concept learning in adolescents. The purpose of this study was to describe and understand the biological world views of a variety of high school students before they take biology courses. Specifically, the study examined student world views in the domains of Classification, Relationship and Causation related to the concepts of heredity, evolution and biotechnology. The following served as guiding questions: (1) What are the personal world views of high school students entering biology classes, related to the domain of Classification, Relationship and Causality? (2) How do these student world views confound or enhance the learning of basic concepts in genetics and evolution? Methods. An interpretive method was chosen for this study. The six student participants were ninth graders and represented a wide range of world view backgrounds. A series of three interviews was conducted with each participant, with a focus group used for triangulation of data. The constant comparative method was used to categorize the data and facilitate the search for meaningful patterns. The analysis included a thick description of each student's personal views of classification, evolution and the appropriate use of biotechnology. Results. The study demonstrates that world view is the basis upon which students build knowledge in biology. The logic of their everyday thinking may not match that of scientists. The words they use are sometimes inconsistent with scientific terminology. This study provides evidence that students voice different opinions depending on the social situation, since they are strongly influenced by peers. Students classify animals based on behaviors. They largely believe that the natural world is unpredictable, and that humans are not really part of that world. Half are unlikely to accept the evolution of humans, but may accept it in other

Graduate students at the University of Virginia (UVa) are volunteering as research advisors on astronomy projects for Virginia's science and technology high schools. In previous years, we have worked with more than a dozen students through a research class at Central Virginia Governor's School in Lynchburg to develop an astronomy research curriculum that teaches background concepts and terminology, guides students in data analysis, and prepares them to present material in poster and oral forums. In our fourth year of operation, we are continuing to work with Central Virginia Governor's School and adapting the research curriculum to an independent course at Roanoke Valley Governor's School in Roanoke. Because both schools are far from UVa in Charlottesville, the program operates remotely; graduate advisors and high school students interact through "virtual" means, establishing a successful framework for meaningful remote mentoring. In the current year, six students will complete projects on astrophysical topics including megamasers, astrochemistry, and pulsars using data taken by the Green Bank Telescope (GBT). Students at Roanoke Valley were directly trained on the GBT as part of a separate outreach program called the Pulsar Search Collaboratory, and all six students will receive hands-on experience in handling GBT data. The current projects are components of larger research efforts by graduate student and professional level researchers, so that the projects contribute to high-level projects only possible with the GBT. This stands as a rare outreach program that uses the principle of “deliberative practice” to train high school students in the development of skills that are crucial to success in science. Furthermore, it provides graduate students with an opportunity to plan and advise research projects, developing a skill set that is required in more advanced academic positions. Our poster discusses the implementation of our online curriculum in two distinct

Sleeping and studying are the day-to-day activities of a teenager attending school. To determine the quality of sleep and its relationship to the academic performance among students attending morning and afternoon shifts in a public high school. Students of the first and second year of high school answered an interview about socio-demographic background, academic performance, student activities and subjective sleep quality; they were evaluated using the Pittsburgh Sleep Quality Index (PSQI). The interview was answered by 322 first year students aged 15 ± 5 years attending the morning shift and 364 second year students, aged 16 ± 0.5 years, attending the afternoon shift. The components: sleep latency, habitual sleep efficiency, sleep disturbance, drug use and daytime dysfunction were similar and classified as good in both school shifts. The components subjective sleep quality and duration of sleep had higher scores among students of the morning shift. The mean grades during the first semester of the students attending morning and afternoon shifts were 5.9 and 5.8, respectively (of a scale from 1 to 7). Among students of both shifts, the PSQI scale was associated inversely and significantly with academic performance. A bad sleep quality influences academic performance in these students.
This study was performed to identify the influencing factors on alienation among high school students. Data was collected by questionnaires from 550 students of academic and vocational high schools in G city. The data was analyzed using descriptive statistics, pearson correlation coefficients, and stepwise multiple regression. The scores of alienation among students in financially lower middle class and lower class were higher than those of the upper middle class students, resulting in significant differences(F=6.87, p=.00). A sense of alienation showed a significantly negative correlation with the scores of responding parenting style(r=-.32), family cohesion(r=-.33), school attachment(r=-.51), academic performance(r=-.34), peer relationships(r=-.38), self-control (r=-.43), and social skills(r=-.33). The most powerful predictor of alienation among high school students was school attachment and the variance explained was 26%. A combination of school attachment, self control, peer relationships, family cohesion, demanding parenting style, and academic performance account for 40% of the variance in alienation among high school students. This study suggests that school attachment, self control, peer relationships, family cohesion, demanding parenting style, and academic performance are significant influencing factors on alienation in high school students. Therefore, nursing strategy is needed to manage these revealed factors.

This study of 1,414 high school earth science and astronomy students characterizes the prevalence of their astronomical misconceptions. The multiple-choice instrument was prepared by scouring the literature on scientific misconceptions for evidence of preconceptions and from the author's interviews with students. Views that were incorrect, but espoused by a large fraction of students, were included as distractors. Results have been analyzed using classical test theory. A linear multiple regression model has helped to show the relative contributions of demographic and school factors to the number of misconceptions held by students. The instrument was found to be a reliable and valid test of students' misconceptions. The mean student score was 34 percent. Fifty-one student misconceptions were revealed by this test, nineteen of which were preferred by students to the correct answer. Several misconceptions appeared more frequently among the higher-performing students. Significant differences in student performance were found in several subgroups based upon schooling and demographic factors. Twenty -five percent out of a total of 30 percent of the variance in total test score could be accounted for by gender, race, and math level courses taken. Grade level and previous enrollment in an earth science course were not found to be predictive of total score. Mother's education proved to be of small import; level of father's education was not significant. This test is a useful addition to instruments that measure student misconceptions. It could find application in tests of effective intervention for conceptual learning. Significantly shortened versions of this instrument that account for 75 and 90 percent of the variance in the forty-seven-item instrument are recommended. Such tests of misconceptions may be somewhat disheartening to teachers and their students. A test made up of only misconception questions will probably have average total scores less than 40 percent.

Astronomy issues are not always adequately handled in the formal education system, as well as, their dissemination in the media is often loaded with sensationalism. However, in this context the students are forming their explanations about it. Therefore, this work has the objective of identifying the possible social representations of students from the Integrated High School on the inductor term Astronomy. It is basically a descriptive research, therefore, a quali-qualitative approach was adopted. The procedures for obtaining the data occurred in the form of a survey, and they involved 653 subjects students from the Integrated High School. The results indicate that the surveyed students have social representations of the object Astronomy, which are based on elements from the formal education space, and also disclosed in the media. In addition, they demonstrate that the students have information about Astronomy, and a value judgment in relation to this science.

This descriptive study compared the science and mathematics aptitudes and achievement test scores for the final school year students in rural White County and Van Buren County, Tennessee with rural county students in Germany. In accordance with the previous research literature (Stevenson, 2002), German students outperformed U.S. students on The International Trends in Math and Science test (TIMSS). As reform in the U.S. education system has been underway, this study intended to compare German county student final school year performance with White County and Van Buren County (Grade 12) performance in science and mathematics. The entire populations of 176 White and Van Buren Counties senior high final school year students were compared with 120 school final year students from two rural German county high schools. The student responses to identical test and questionnaire items were compared using the t-test statistical analysis. In conclusion after t-test analyses, there was no significant difference (p>.05 level) in student attitudes on the 27 problem achievement and the 35 TIMSS questionnaire items between the sampled population of 120 German students compared with the population of 176 White and Van Buren students. Also, there was no statistically significant difference (p>.05 level) between the German, White, and Van Buren County rural science and math achievement in the TIMSS problem section of the final year test. Based on the research, recommendations to improve U.S. student scores to number one in the world include making changes in teaching methodology in mathematics and science; incorporating pamphlet lessons rather than heavily reliance on textbooks; focusing on problem solving; establishing an online clearinghouse for effective lessons; creating national standards in mathematics and science; matching students' course choices to job aspirations; tracking misbehaving students rather than mainstreaming them into the regular classroom; and designing

The Education and Public Outreach group at the National Optical Astronomy Observatory has designed an outside-of-school education program to excite the interest of talented youth in future projects like the Large Synoptic Survey Telescope (LSST) and the NOAO (archival) Data Lab - their data approaches and key science projects. Originally funded by the LSST Corporation, the program cultivates talented youth to enter STEM disciplines and serves as a model to disseminate to the 40+ institutions involved in LSST. One Saturday a month during the academic year, high school students have the opportunity to interact with expert astronomers who work with large astronomical data sets in their scientific work. Students learn about killer asteroids, the birth and death of stars, colliding galaxies, the structure of the universe, gravitational waves, dark energy, dark matter, and more. The format for the Saturday science cafés has been a short presentation, discussion (plus food), computer lab activity and more discussion. They last about 2.5 hours and have been planned by a group of interested local high school students, an undergraduate student coordinator, the presenting astronomers, the program director and an evaluator. High school youth leaders help ensure an enjoyable and successful program for fellow students. They help their fellow students with the activities and help evaluate how well the science café went. Their remarks shape the next science café and improve the program. The experience offers youth leaders ownership of the program, opportunities to take on responsibilities and learn leadership and communication skills, as well as foster their continued interests in STEM. The prototype Big Data Science Academy was implemented successfully in the Spring 2017 and engaged almost 40 teens from greater Tucson in the fundamentals of astronomy concepts and research. As with any first implementation there were bumps. However, staff, scientists, and student leaders all

To investigate the perception and actual use of mobile phones among Japanese high school students while riding their bicycles, and their experience of bicycle crash/near-crash. A questionnaire survey was carried out at high schools that were, at the time of the survey, commissioned by the National Agency for the Advancement of Sports and Health to conduct school safety research. In the survey, we found that mobile phone use while riding a bicycle was quite common among the students during their commute, but those who have a higher perception of danger in this practice, and those who perceived that this practice is prohibited, were less likely to engage in this practice. Male students and students commuting to school by bicycle only were more likely to have used phones while riding. There was a significant relationship between phone usage while riding a bicycle and the experience of bicycle crash/near-crash, although its causality was not established. Bicycle crash/near-crash experienced while using a phone was less prevalent among the students who had a higher perception of danger in phone usage while riding, students who perceived that this practice is prohibited, and students with a shorter travel time by bicycle during the commute. Since mobile phone use while riding a bicycle potentially increases crash risk among cyclists, student bicycle commuters should be made aware of this risk. Moreover, they should be informed that cyclists' phone usage while riding is prohibited according to the road traffic law.

Like others, Thailand education strongly focused on STEM education. This paper aimed to examine existing Thai high school students' integrated knowledge about science, technology, engineering, and mathematics (STEM) in their developing science project. The participants included 49 high school students were studying the subject of individual study (IS) in Khon Kaen wittayayon school, Khon Kaen, Thailand. The IS was provided to gradually enhance students to know how to do science project starting from getting start to do science projects, They enrolled to study the individual study of science project for three year in roll. Methodology was qualitative research. Views of students' integrated knowledge about STEM were interpreted through participant observation, interview, and students' science projects. The first author as participant observation has taught this group of students for 3 years. It found that 16 science projects were developed. Views of students' integrated knowledge about STEM could be categorized into three categories. These included (1) completely indicated integration of knowledge about science, technology, engineering, and mathematics, (2) partial indicated integration of knowledge about science, technology, engineering, and mathematics, and (3) no integration. The findings revealed that majority of science projects could be categorized as completely indicated integration of knowledge about science, technology, engineering, and mathematics. The paper suggested some ideas of enhancing students to applying STEM for developing science projects.

Modular Enteral Nutrition may be a substitute for Parenteral Nutrition in children with different pathologies. Study of 4 children with different pathologies selected from a group of 40 admitted to the Maternal-Childrens Hospital "Valle de Hebrón" in Barcelona, who received modular enteral nutrition. They were monitored on a daily basis by the Dietician Service. Modular enteral nutrition consists of modules of proteins, peptides, lipids, glucids and mineral salts-vitamins. 1.--Craneo-encephalic traumatisms with loss of consciousness, Feeding with a combination of parenteral nutrition and modular enteral nutrition for 7 days. In view of the tolerance and good results of the modular enteral nutrition, the parenteral nutrition was suspended and modular enteral nutrition alone used up to a total of 43 days. 2.--55% burns with 36 days of hyperproteic modular enteral nutrition together with normal feeding. A more rapid recovery was achieved with an increase in total proteins and albumin. 3.--Persistent diarrhoea with 31 days of modular enteral nutrition, 5 days on parenteral nutrition alone and 8 days on combined parenteral nutrition and modular enteral nutrition. In view of the tolerance and good results of the modular enteral nutrition, the parenteral nutrition was suspended. 4.--Mucoviscidosis with a total of 19 days on modular enteral nutrition, 12 of which were exclusively on modular enteral nutrition and 7 as a night supplement to normal feeding. We administered proteic intakes of up to 20% of the total calorific intake and in concentrations of up to 1.2 calories/ml of the final preparation, always with a good tolerance. Modular enteral nutrition can and should be used as a substitute for parenteral nutrition in children with different pathologies, thus preventing the complications inherent in parenteral nutrition.

Microscopic enteritis (ME) is an inflammatory condition of the small bowel that leads to gastrointestinal symptoms, nutrient and micronutrient deficiency. It is characterised by microscopic or sub-microscopic abnormalities such as microvillus changes and enterocytic alterations in the absence of definite macroscopic changes using standard modern endoscopy. This work recognises a need to characterize disorders with microscopic and submicroscopic features, currently regarded as functional or non-specific entities, to obtain further understanding of their clinical relevance. The consensus working party reviewed statements about the aetiology, diagnosis and symptoms associated with ME and proposes an algorithm for its investigation and treatment. Following the 5(th) International Course in Digestive Pathology in Bucharest in November 2012, an international group of 21 interested pathologists and gastroenterologists formed a working party with a view to formulating a consensus statement on ME. A five-step agreement scale (from strong agreement to strong disagreement) was used to score 21 statements, independently. There was strong agreement on all statements about ME histology (95%-100%). Statements concerning diagnosis achieved 85% to 100% agreement. A statement on the management of ME elicited agreement from the lowest rate (60%) up to 100%. The remaining two categories showed general agreement between experts on clinical presentation (75%-95%) and pathogenesis (80%-90%) of ME. There was strong agreement on the histological definition of ME. Weaker agreement on management indicates a need for further investigations, better definitions and clinical trials to produce quality guidelines for management. This ME consensus is a step toward greater recognition of a significant entity affecting symptomatic patients previously labelled as non-specific or functional enteropathy.

When exposed to low temperatures, many insect species enter a reversible comatose state (chill coma), which is driven by a failure of neuromuscular function. Chill coma and chill coma recovery have been associated with a loss and recovery of ion-homeostasis (particularly extracellular [K......+]) and accordingly onset of chill coma has been hypothesised to result from depolarization of membrane potential caused by loss of ion-homeostasis. Here we examined whether onset of chill coma is associated with a disturbance in ion balance by examining the correlation between disruption of ion homeostasis and onset...... of chill coma in locusts exposed to cold at varying rates of cooling. Chill coma onset temperature changed maximally 1°C under different cooling rates and marked disturbances of ion homeostasis were not observed at any of the cooling rates. In a second set of experiments we used isolated tibial muscle...

Full Text Available Learning second language considers a number of factors that influence the manner in which the language is taught. Understanding of the learners’ goals and motivation for learning is one. Using descriptive-correlational research design, this study determined the influence of student English utility and teacher efficacy on the students’ English proficiency. A total of 101 students from first year to fourth year level served as the respondents of the study. The study quantified the students’ perception towards English utility and their evaluation of English teacher efficacy which employed a researcher-made survey questionnaire. Results revealed high positive perceptions of students towards English utility. Analysis of variance revealed significant differences in the perceptions of high school students on the efficacy of their English teachers. Correlation coefficients indicated a positive linear relationship among the given variables. The p-value revealed significant relationship of teacher efficacy (r = .691, p-value = .000 and English utility (r = .467, p-value = .000 to students’ English proficiency. Results of regression statistics revealed that English utility has no significant influence on the student English proficiency. Therefore, the main factor that must still be considered then should be the teacher. Finally, there is an explicit indication that high level of teachers’ efficacy performing in teaching has much powerful influence on the English proficiency of high school students. Thus improving the methods of teaching English provides a better way of motivating students to achieve higher levels of proficiency in the future.
Full Text Available The analysis of attitudes and value orientations of high school students comes as the result of research based on data collected during April-June 2011 in six towns in Serbia. The main objective of this research was to detect the dominant attitudes and value orientations of high school students on a scale of traditionalism, homophobia, anti-Romism, ethnic stereotypes and attitudes toward abortion. The research was conducted in the following cities: Belgrade, Krusevac, Novi Sad, Zrenjanin, Nis and Novi Pazar. The results showed that high school students in Serbia in regards to their beliefs do not differ much from the general social climate in which they grew up and were educated in. Traditional respondents are represented at the level of 33.9%; 27.9% of them are moderately traditional and 25% of them are non-traditional. On the one side there are extremely radical position of high school students especially in relation to Roma and LGBT people. On the other side, certain number of respondents howed high affinity and positive individual interprets of the lifestyles of those groups (such as the rights of marriage for homosexual population. Attitudes towards women's rights are also bipolar - high school students have a patriarchal attitude towards marriage, family and abortion, but they show sensitivity to the issue of domestic violence. The obtained data should be interpreted in accordance with the changes in Serbian society - economic crisis, privatization, increase of violence in society and family, redefining of gender roles, etc.

Full Text Available The current interest in introducing the dual education system into Serbian secondary education has drawn our attention to the question of students' self-perception in the process of practical teaching. The idea that underpins this paper is the supposition that students are affectively engaged with the work activities they perform. The Utrecht Work Engagement Scale (UWES (Schaufeli et al., 2002 has been used for assessing students' work engagement in practical teaching. A study was conducted to examine the differences between high school students with mild intellectual disabilities and those with typical development with regard to aspects of work engagement defined as Energy, Commitment and Absorption. The sample was comprised of 248 students of vocational high schools in Serbia of both genders, of whom 111 with intellectual disabilities and 137 with typical development. The findings indicate that students with mild intellectual disabilities tend to rate their engagement in practical teaching more positively (t=7,457; p=0,001 than students with typical development. The paper provides a detailed analysis of the pedagogical implications of these findings and also outlines the limitations of the study, thus pointing the way for future research on this or related issues.
Full Text Available The level of social and moral maturity of high-school students was examined. There were almost no significant differences between the students of two different educational programs. In general, the students' level of social and moral maturity is satisfyingly high, but their social skills are not quite appropriately developed. The results of behaviour in school situations reveal a quite unpleasant picture of interpersonal relations, which is probably a reflection of social relations in society. The absence of correlations between both components of maturity and social skills shows the gap between human's reasoning and behaviour. Students know, which behaviour is moral and socially adapted, but they do not always act in congruence with that, because existing social relations often encourage different behaviour.

Argumentation is one factor that can help improve critical thinking skills. Arguing means to defend statements with the various data, denials, evidence, and reinforcement that support the statement. The research aimed to capture the quality of argument skills by students in grade 12 high school students and in postgraduate student on social-scientific issues of cancer. Both group subjects are not in the same school or institution, chosen purposively with the subject of 39 high school students of grade 12 in one district of West Java and 13 students of Biology education postgraduate in one of University in West Java - Indonesia. The results of the quality structure of arguments in both subject groups show the same pattern, which is claim - warrant - and ground, with the quality of counterclaim aspects on the postgraduate students look better than grade 12 students. This provides an illustration that the ability in argumentation between students and teachers in the socio-scientific issue of cancer should be evaluate so that the learning process would be more refined in schools.

The main objective of this study was to investigate the prevalence of taste hyposensitivity and the relationships between sex, oral health status, and eating habits with taste hyposensitivity in Japanese senior high school students. Oral examinations, sweet and salt whole-mouth taste tests, and a questionnaire about eating habits were conducted on 234 senior high school students. Factors affecting taste hyposensitivity were investigated using a multivariate analysis. Sweet-taste hyposensitivity was observed in 7.3% of the students, and salt-taste hyposensitivity in 22.2%. Approximately 3% of the students had both sweet- and salt-taste hyposensitivity, and 22.6% had either sweet- or salt-taste hyposensitivity. In total, 26% had a taste hyposensitivity. There were significant relationships between the intake of instant noodles with sweet-taste hyposensitivity, and the intake of vegetables or isotonic drinks with salt-taste hyposensitivity. There was a significant association between eating habits and taste hyposensitivity in Japanese senior high school students. Taste tests would be a helpful adjunct for students to recognize variations in taste sensitivity, and a questionnaire about their eating habits might provide an effective self-review of their eating habits, and therefore, provide motivation to change. © 2011 Blackwell Publishing Asia Pty Ltd.

Adolescents are known to have high risk factors for sleep disorders, yet the youth rates of sleep disturbances are unknown. This study aimed to determine the prevalence of sleep disorders among New Zealand high school students. The Auckland Sleep Questionnaire (ASQ) was administered to high school students at six schools in the North Island. Schools were chosen to reflect a range of ethnicities and school deciles, which identify the socioeconomic status of households in the school catchment area. A total of 1388 students completed the ASQ. The median age was 17 years (range 14-23) and females represented 43.5% (n=604) of the total group. A total of 37.2% of the students surveyed reported having significant sleep symptoms lasting longer than one month. Depression and anxiety were present in 51.7% and 44.8% of students reporting a sleep problem, respectively. A moderate correlation was observed between sleep problems and depression (r=0.34, psleep problems and anxiety (r=0.31, pstudents with sleep symptoms (12.2% and 5.5% respectively). No difference was found in the rate of sleep problems reported by different ethnic groups. A considerable proportion of students surveyed reported significant sleep symptoms. This study has the potential to aid physicians within New Zealand in better appreciating the burden of sleep disorders faced by young people and in effectively assessing and managing different causes of sleep symptoms in this demographic.

Research has shown that hearing loss in musicians may cause difficulty in timbre recognition and tuning of instruments. To analyze the hearing thresholds from 250 Hz to 16,000 Hz in a group of music students and compare them to a non-musician group in order to determine whether high-frequency audiometry is a useful tool in the early detection of hearing impairment. Study design was a retrospective observational cohort. Conventional and high-frequency audiometry was performed in 42 music students (Madsen Itera II audiometer and TDH39P headphones for conventional audiometry, and HDA 200 headphones for high-frequency audiometry). Of the 42 students, 38.1% were female students and 61.9% were male students, with a mean age of 26 years. At conventional audiometry, 92.85% had hearing thresholds within normal limits; but even within the normal limits, the worst results were observed in the left ear for all frequencies, except for 4000 Hz; compared to the non-musician group, the worst results occurred at 500 Hz in the left ear, and at 250 Hz, 6000 Hz, 9000 Hz, 10,000 Hz, and 11,200 Hz in both the ears. The periodic evaluation of high-frequency thresholds may be useful in the early detection of hearing loss in musicians.

Full Text Available INTRODUCTION: We describe the epidemiology of intestinal parasites in patients from an AIDS reference service in Northeastern São Paulo, Brazil. METHODS: Retrospective evaluation was done for all HIV-1/AIDS-positive patients whose Hospital de Base/São José do Rio Preto laboratorial analysis was positive for enteroparasites after diagnosis of HIV-1 infection, from January 1998 to December 2008. Statistical analysis was performed using the R statistical software version 2.4.1. The level of significance adopted was 5%. RESULTS: The most frequent protozoan was Isospora belli (4.2%, followed by Giardia lamblia (3.5%, Entamoeba coli (2.8%, and Cryptosporidium parvum (0.3%. Ancylostoma duodenale (1.4% was the most frequently detected helminth, while Taenia saginata and Strongiloides stercoralis were found in 0.7% of the samples. The results showed that diarrhea was significantly associated with giardiasis and isosporiasis. However, no association was observed between CD4+ cell counts, viral load, and the characteristics of any particular parasite. CONCLUSIONS: Our data may be useful for further comparisons with other Brazilian regions and other developing countries. The data may also provide important clues toward improving the understanding, prevention, and control of enteric parasites around the world.

Center for Multiscale Modeling of Atmospheric Processes (CMMAP) is a National Science Foundation Science and Technology Center focused on improving the representation of cloud processes in climate models. The Center is divided into three sections including Knowledge Transfer, Research, and Education and Diversity. The Science Education and Diversity mission is to educate and train people with diverse backgrounds in Climate and Earth System Science by enhancing teaching and learning and disseminating science results through multiple media. CMMAP is partnering with two local school districts to host an annual global climate conferences for high school students. The 2008 Colorado Global Climate Conference seeks "To educate students on global and local climate issues and empower them to se their knowledge." The conference is sponsored by CMMAP, The Governor's Energy Office, Poudre School District, Thompson School District, Clif Bar, and Ben and Jerry's Scoop Shop of Fort Collins. The conference seeks to inspire students to pursue future education and careers in science fields. Following an opening welcome from the Governor's Energy Office, Keynote Piers Sellers will discuss his experiences as an atmospheric scientist and NASA astronaut. Students will then attend 3 out of 16 breakout sessions including such sessions as "Hot poems, Cool Paintings, and the treasures of Antiquity of Climate Change", "Mitigation vs Adaptation", "Bigfoot Walks(What Size is our carbon footprint?)" "The Wedges: Reduc ing Carbon Emissions", and "We the People: Climate and Culture of Climate Change" to name a few. Using The Governor's High School Conference on the Environment sponsored by the Wisconsin Center for Environmental Education as a model we are developing statewide partnerships to bring high school students together to look at global climate issues that will impact their future and of which they can be part of the solution through their education and career paths. In addition to
Presenting science is an authentic activity of practicing scientists. Thus, effective communication of science is an important skill to nurture in high school students who are learning science. This study examines strategies employed by high school students as they make science presentations; it assesses students' conceptual understandings of particular science topics through their presentations and investigates gender differences. Data are derived from science presentation given by eight high school students, three females and five males who attended a summer science program. Data sources included videotaped presentations, ethnographic fieldnotes, interviews with presenters and members of the audience, and presenter notes and overheads. Presentations were transcribed and submitted to discourse analysis from an interactional sociolinguistic perspective. This article focuses on the methodology employed and how it helps inform the above research questions. The author argues that use of this methodology leads to findings that inform important social-communicative issues in the learning of science. Practical advice for teaching students to present science, implications for use of presentations to assess conceptual learning, and indications of some possible gender differences are discussed.Received: 14 April 1993; Revised: 15 February 1994;

Full Text Available BACKGROUND. Student role performance for academic success in secondary education is under represented in the occupational therapy literature, despite the persistently high dropout rate in the United States (Stillwell & Sable, 2013. Executive dysfunction is one of many possible contributors to difficulties in the classroom (Dirette & Kolak, 2004 and is a better indicator of school performance than IQ (Diamond, 2012. This research examined executive functioning of both alternative and traditional high school students to determine if there is a relationship between executive function and academic success as measured by cumulative grade point average. METHOD. 132 high school students from three different school settings were given the Behavioral Rating Inventory of Executive Function-Self Report (BRIEF-SR. The Global Executive Composite (GEC and individual subscale scores were compared to GPA. RESULTS. No significant difference in GEC scores was found among settings. Subscale scores for “inhibition” and “task completion” were significantly different in the alternative school setting. A weak negative correlation was seen between the GEC and GPA. However, academically unsuccessful students scored statistically lower on the GEC. CONCLUSION. Global executive dysfunction was not predicted by setting but was seen in academically unsuccessful students.
Full Text Available INTRODUCTION: Adolescents are known to have high risk factors for sleep disorders, yet the youth rates of sleep disturbances are unknown. AIM: This study aimed to determine the prevalence of sleep disorders among New Zealand high school students. METHODS: The Auckland Sleep Questionnaire (ASQ was administered to high school students at six schools in the North Island. Schools were chosen to reflect a range of ethnicities and school deciles, which identify the socioeconomic status of households in the school catchment area. RESULTS: A total of 1388 students completed the ASQ. The median age was 17 years (range 14-23 and females represented 43.5% (n=604 of the total group. A total of 37.2% of the students surveyed reported having significant sleep symptoms lasting longer than one month. Depression and anxiety were present in 51.7% and 44.8% of students reporting a sleep problem, respectively. A moderate correlation was observed between sleep problems and depression (r=0.34, p<0.01, and sleep problems and anxiety (r=0.31, p<0.01. Problem alcohol use and other substance use were more common in students with sleep symptoms (12.2% and 5.5% respectively. No difference was found in the rate of sleep problems reported by different ethnic groups. DISCUSSION: A considerable proportion of students surveyed reported significant sleep symptoms. This study has the potential to aid physicians within New Zealand in better appreciating the burden of sleep disorders faced by young people and in effectively assessing and managing different causes of sleep symptoms in this demographic.

This study aims to investigate smoking patterns in high school student and to give student smoker effective information. The sample of 250 male high school students out of two different schools in Tae-Jŏn was questioned from July 10th to 15th, 1995. In analyzing these date, the statistics shows the realities by means of number of students. The results are summarized into 17 items as follows. Regarding the level of smoking, 140 students out of 250 admit that they have ever smoked, 52.1% of smoking students say that the motivation of beginning smoking is mainly curiosity. The survey shows that 22.9% of smoking students feel very good when smoking. It also shows that 30.0% of smoking students began smoking in the first grade of high school. With regard to the volume of smoking per day, 41.4% of smoking students smoke variably, 42.1% drink when smoking, 15.0% spend more than W 70,000 a month. About the question who knows the fact of their smoking, 51.5% answer that their friends know the fact of their smoking. In regard to the reslationship between smoking and school performance, 18.2% of non smoking students make poor grades as compared with 40% of smoking students, 9.3% of smoking students say that they are satisfied with the school life, but 35.7% of them are not satisfied. Regarding the attitude to smoking teachers, 35% of smoking students state that they are affected by them. 69.3% of smoking students say that they will stop smoking, while the remaining 30.7% say that they will keep smoking. The reason of 63.9% to stop smoking is that smoking is bad for the health. The reason of 46.5% to keep smoking is the acquired habit of smoking. 97.2% know the fact that the major element of cigarettes is nicotine and it is very harmful to the health. 40.8% recognize the harmful effect of smoking by TV and radio programs. 97.2% know that smoking could cause lung cancer. From the above results. I propose as follows We should make specific plan to keep smoking by simple
To review and discuss the evidence and arguments to combine enteral nutrition and parenteral nutrition in the ICU, in particular with reference to the Early Parenteral Nutrition Completing Enteral Nutrition in Adult Critically Ill Patients (EPaNIC) study. The EPaNIC study shows an advantage in terms of discharges alive from the ICU when parenteral nutrition is delayed to day 8 as compared with combining enteral nutrition and parenteral nutrition from day 3 of ICU stay. The difference between the guidelines from the European Society of Enteral and Parenteral Nutrition in Europe and American Society for Parenteral and Enteral Nutrition/Society of Critical Care Medicine in North America concerning the combination of enteral nutrition and parenteral nutrition during the initial week of ICU stay was reviewed. The EPaNIC study clearly demonstrates that early parenteral nutrition in the ICU is not in the best interests of most patients. Exactly at what time point the combination of enteral nutrition and parenteral nutrition should be considered is still an open question.

Current literature reports that the astronomy education is motivating and interesting for basic education, but the content suggested by the national curriculum guidelines do not seem to attract students and teachers in order to transcend the discipline of Science in the elementary School or Physics in High School. By applying a questionnaire to 80 students of High School and participants of Brazilian Olympiad of Astronomy and Astronautics of two schools of São Paulo state, we obtained results that indicate that astronomy topics that really motivate students are topics linked to science fiction and current research, which are the subject of extensive media release and have a strong interdisciplinary character. At the end of the work we suggest a new context for astronomy education, by inserting topics combined with other areas of knowledge to what we call “interdisciplinary astrophysics teaching”.

This article is a report of a mixed method study of the association between personality traits of nurses and their reasons for entering nursing. Background. The worldwide nursing shortage prompts research into better understanding of why individuals enter nursing and may assist in exploring ways to increase their recruitment and long term retention. A mixed method sequential explanatory design employed semi-structured interviews and a validated personality inventory measuring temperament and character traits. Registered Nurses (n = 12) and nursing students (n = 11) working and studying in a regional area of Queensland Australia were purposively sampled for the interviews in 2010 from their participation in the survey in 2009 investigating their personality traits. Qualitative data collection stopped at saturation. A thematic content analysis of the qualitative data using the framework approach was interpreted alongside their personality trait profiles. Two dominant themes were identified from the participant interviews about reasons for entering nursing; 'opportunity for caring' and 'my vocation in life'. These themes were congruent with key temperament and character traits measured in the participants. All nurses and students were very high in traits that exude empathy and altruistic ideals regardless of other characteristics which included highly pragmatic and self-serving principles. Qualitative and quantitative findings suggest that a caring nature is a principal quality of the nursing personality. Recruitment and retention strategies whilst promoting multiple benefits for the profession should not forget that the prime impetus for entering nursing is the opportunity to care for others. © 2012 Blackwell Publishing Ltd.
Full Text Available BACKGROUND Nutrients form the fuel for the body, which comes in the form of carbohydrates, proteins and lipids. The body is intended to burn fuels in order to perform work. Starvation with malnutrition affects the postoperative patients and patients with acute pancreatitis. There is an increased risk of nosocomial infections and a delay in the wound healing may be noted. They are more prone for respiratory tract infections. Enteral Nutrition (EN delivers nutrition to the body through gastrointestinal tract. This also includes the oral feeding. This study will review the administration, rationale and assess the pros and cons associated with the early initiation of enteral feeding. The aim of this study is to evaluate if early commencement of enteral nutrition compared to traditional management (delayed enteral feeding is associated with fewer complications and improved outcome- In patients undergoing elective/emergency gastrointestinal surgery. In patients with acute pancreatitis. It is also used to determine whether a period of starvation (nil by mouth after gastrointestinal surgery or in the early days of acute pancreatitis is beneficial in terms of specific outcomes. MATERIALS AND METHODS A prospective cohort interventional study was conducted using 100 patients from July 2012 to November 2012. Patients satisfying the inclusion and exclusion criteria were included in the study. Patients admitted in my unit for GIT surgeries or acute pancreatitis constituted the test group, while patients admitted in other units for similar disease processes constituted the control group. RESULTS Our study concluded that early enteral feeding resulted in reduced incidence of surgical site infections. When the decreased length of stay, shorter convalescent period and the lesser post-interventional fatigue were taken into account, early enteral feeding has a definite cost benefit.CONCLUSION Early enteral feeding was beneficial associated with fewer

Every summer for the past 26 years the University of New Hampshire (UNH) has run a month-long, residential outreach program for high school students considering careers in mathematics, science, or engineering. Space science is one of the modules. Students work directly with UNH faculty performing original work with real spacecraft data and hardware and present the results of that effort at the end of the program. This year the student research projects used data from the Messenger, STEREO, and Triana missions. In addition, the students build and fly a high-altitude balloon payload with instruments of their own construction. Students learn circuit design and construction, microcontroller programming, and core atmospheric and space science along with fundamental concepts in space physics and engineering. Our payload design has evolved significantly since the first flight of a simple rectangular box and now involves a stable descent vehicle that does not require a parachute. Our flight hardware includes an on-board flight control computer, in-flight autonomous control and data acquisition of multiple student-built instruments, and real-time camera images sent to ground. This year we developed, built and flew a successful line cutter based on GPS location information that prevents our payload from falling into the ocean while also separating the payload from the balloon remains for a cleaner descent. We will describe that new line cutter design and implementation along with the shielded Geiger counters that we flew as part of our cosmic ray air shower experiment. This is a program that can be used as a model for other schools to follow and that high schools can initiate. More information can be found at .
Full Text Available Abstract In the present paper that comprises the problems of the relation between young cultures and learning are studied, as well as the transmission problems between young people and teachers, in the first year of Middle School. It is a qualitative research which studied deeply some cases. The research makes a comparison among young students and teachers. We use two techniques of research: the semi structured interview and the discussion group. The general objectives are explore and describe the meanings that the incorporation of mass media of communication gets for the for young identities, as well as the consumption and production of young cultures and the impact which introduces their meanings into the generational transmition process between teachers and young people. From our results, we propose three discussion axes: the massification which involves for young people the consumption of young cultures in the first year of Middle School, does not allow visualize, and it could cover up interpersonal violence relations and inequality among themselves as well as their positions of cultural producers; it does exist for young people a marked dissociation in the classroom: on one side, there are the interactions between the group members and consumption/production of young cultures, and, on the other side, the school culture, and the learning process; the problem of attention/inattention of young people in the learning process in the class, is linked to the transmission process, which is produced between teachers and students in the entry into the Middle School. Keywords: Pedagogy. Youth Cultures. Middle School.

India has a high burden of tuberculosis in terms of incidence, prevalence and mortality. RNTCP in India follows a passive case detection method for case finding in chest symptomatics. This makes it essential for the community at large and the younger generation in particular to have adequate knowledge and awareness regarding tuberculosis since it is highly infectious. High school children can be effectively sensitised and motivated to be change agents in the community and play a key role in combating tuberculosis. AIM To assess the awareness levels of 8 th to 10 th grade school students in Amalapuram, a town in coastal area of Andhra Pradesh regarding tuberculosis. MATERIAL AND METHODS After the study protocol was cleared by the Institutional Ethics Committee of Konaseema Institute of Medical Sciences and Research Foundation, Amalapuram, permission was sought from the authorities of five private schools and one government school in Amalapuram to carry out this study among the 8 th to 10 th grade students of these schools. A predesigned, pretested semi-structured questionnaire was used to capture information related to basic demographic details of the participants followed by questions related tuberculosis to assess their awareness. A cross-sectional survey was carried out and once the filled-in questionnaires were collected, an interactive session was held where various aspects of tuberculosis were elaborately explained, the answers to the questions were told in detail and doubts of the students were clarified. STATISTICAL ANALYSIS The data collected was entered into a template created in computer using Microsoft Excel 2007. EPI INFO 6 software was used for

The goal of this project was to provide an opportunity for high school students to participate in university-level research projects. In this case, students from Pinkerton Academy (Derry, New Hampshire) were invited to participate in efforts to catalog data from the COMPTEL experiment on NASA's Compton Gamma-Ray Observatory (CGRO). These activities were part of a senior level honors course at Pinkerton. Although the success of this particular program was rather limited, we feel that the general concept is a sound one. In principle, the concept of partnerships between local schools and university researchers is one that could be especially attractive to soft money researchers. Programs can be carefully designed to benefit both the students and the research program.

Astronomy-related contents exist in almost all levels of basic education in Brazil and are also frequently disseminated through mass media. Thus, students form their own explanations about the phenomena studied by this science. Therefore, this work has the objective of identifying the possible social background of the Integrated High School students on the term Astronomy. It is a research of a basic nature, descriptive, and for that reason a quali-quantitative approach was adopted; the procedures to obtain the data were effected in the form of a survey. The results show that the tested students have a social background about the object Astronomy, which is on the one hand fortified by elements they have made or which is part of the experience lived by the respondents within the formal space of education, and on the other hand based on elements possibly disseminated through the mass media.

Members of nursing faculty are utilizing interactive teaching tools to improve nursing student's clinical judgment; one method that has been found to be potentially effective is high fidelity simulation (HFS). The purpose of this time series design study was to determine whether undergraduate nursing students were able to transfer knowledge and skills learned from classroom lecture and a HFS clinical to the traditional clinical setting. Students (n=42) were observed and rated on their ability to perform a respiratory assessment. The observations and ratings took place at the bedside, prior to a respiratory lecture, following the respiratory lecture, and following simulation clinical. The findings indicated that there was a significant difference (p=0.000) in transfer of learning demonstrated over time. Transfer of learning was demonstrated and the use of HFS was found to be an effective learning and teaching method. Implications of results are discussed.

To investigate the sleep status of college and high schools students. Pittsburgh sleep quality index (PSQI) and self-manufactured questionnaires about siesta habits were used as tools. Three groups of students from medical college (MC), senior high school (SS) and junior high school (JS) were surveyed. In the group MC, SS and JS, the occurrence rates of sleep disorders were 27%, 62% and 54%, respectively, and in which the appearance rates of insomnia were 17%, 19% and 19%, longing for sleep were 10%, 43% and 35% respectively. And there were no significant difference between schoolboy and schoolgirl. The occurrence rates of slack breathing were different (5/155, 1/154) significantly between group SS and JS. The distinct differences also were found in group JS and MC, in which students felt hot (10/155, 1/122) and in all the three groups, in which students felt sleepy (55/155, 62/154, 13/122) whereas the difference of sleepy between group SS and JS was comparatively distinct (55/155, 62/154). Significant differences were also found between group JS and SS, MC in average sleep time of (7.65 +/- 0.87) hours, (7.16 +/- 0.83) hours, and (7.10 +/- 0.57) hours. The time of falling asleep (median 15 min, 10 min, 20 min) and siesta habit (8/155, 19/154, 75/122) among group MC and SS, JS were different respectively and markedly, whereas siesta habit differences between group SS and JS were comparatively distinct (8/155, 19/154). Students in high school showed higher rate of longing for sleep, and this implicated they fall short of sleep time greatly and siesta could improve their sleepy signs.

Based on a synthesis of literature, earlier studies, analyses and observations on high school students, this study developed an initial framework for assessing students' statistical reasoning about descriptive statistics. Framework descriptors were established across five levels of statistical reasoning and four key constructs. The former consisted of idiosyncratic reasoning, verbal reasoning, transitional reasoning, procedural reasoning, and integrated process reasoning. The latter include describing data, organizing and reducing data, representing data, and analyzing and interpreting data. In contrast to earlier studies, this initial framework formulated a complete and coherent statistical reasoning framework. A statistical reasoning assessment tool was then constructed from this initial framework. The tool was administered to 10 tenth-grade students in a task-based interview. The initial framework was refined, and the statistical reasoning assessment tool was revised. The ten students then participated in the second task-based interview, and the data obtained were used to validate the framework. The findings showed that the students' statistical reasoning levels were consistent across the four constructs, and this result confirmed the framework's cohesion. Developed to contribute to statistics education, this newly developed statistical reasoning framework provides a guide for planning learning goals and designing instruction and assessments.
Full Text Available Writing in English is one of the language skills that are taught in the context of learning English as a Foreign Language (EFL in Indonesian senior high schools. According to previous studies, most of the students consider writing is the most difficult of the four skills. This research was aimed at finding out the main difficulties in writing faced by the grade XI students at SMA Negeri 10 Fajar Harapan, Banda Aceh, and the efforts made by their teacher to overcome those problems. The design of this study was a descriptive qualitative study. To obtain the data, the writers used document collection and interviews. The results from the document collection showed that the highest percentages of problems faced by the students were in the aspect of language use and the least problems were in the aspect of content. The results from the interviews showed that the most common correcting efforts made by the teacher were giving written feedback for all aspects of writing i.e. language use, mechanics, vocabulary, organization, and content. Likewise, teachers need to develop systemized forms of feedback and make it clear to students what the feedback means and what they are to do with them to assist students in improving their writing skills.

Full Text Available This study investigated the desirable educational background for a teacher to work with high ability/gifted students, desirable characteristics these teachers should present and conceptions on high ability/giftedness. The participants were 20 public school teachers from a city surrounding Brasilia. Of this group, ten were elementary school teachers working with initial grades and ten were undergraduate Pedagogy teachers. A qualitative approach was used and data were collected by means of a semi-structured interview. A content analysis was then conducted. In relation to the desirable educational background for a teach of high ability/gifted students, participants indicated the need of continuous training, under graduation curriculum adapted to the theme and graduation courses in the area. The desirable features for teachers of high ability/gifted students were related to personological attributes (personality traits and intellectual ability, as well as professional characteristics. The conceptions on high ability/giftedness presented by the participants were, in general, close to those found in the literature and used as reference for this study. However, there was lack of information on how to apply the theory into real practice, as well as several wrong ideas on the topic.

This study aimed to elucidate the mechanisms and kinetics of coating failure for enteric coated beads exposed to high-humidity conditions at different storage temperatures. Enteric coated beads were placed on high-humidity conditions (75 to 98% relative humidity (RH)) in the temperature range of 5 to 40°C. These stability samples of beads were tested for acid dissolution and water activity and also analyzed with SEM, X-ray CT, and DMA. Exposure of enteric coated beads to high humidity led to increased gastric release of drug which eventually failed the dissolution specification. SEM showed visible cracks on the surface of beads exposed to 5°C/high humidity and fusion of enteric beads into agglomerates at 40°C/high humidity. In a non-destructive time elapse study, X-ray CT demonstrated swelling of microcrystalline cellulose cores, crack initiation, and propagation through the API layer within days under 5°C/98% RH storage conditions and ultimately fracture through the enteric coating. DMA data showed a marked reduction in T g of the enteric coating materials after exposure to humidity. At 5°C/high humidity, the hygroscopic microcrystalline cellulose core absorbed moisture leading to core swelling and consequent fracture through the brittle API and enteric layers. At 40°C (high humidity) which is above the T g of the enteric polymer, enteric coated beads coalesced into agglomerates due to melt flow of the enteric coating. We believe it is the first report on two distinct failure models of enteric coated dosage forms.

This article describes how the Population Communication Services (PCS) has seized on the "enter-educate" approach, the blending of popular entertainment with social messages, to change reproductive health behavior. The enter-educate approach spreads its message through songs, soap operas, variety shows, and other types of popular entertainment mediums. Because they entertain, enter-educate projects can capture the attention of an audience -- such as young people -- who would otherwise scorn social messages. And the use of population mediums makes it possible to reach a variety of audiences. Funded by USAID, PCS began its first enter-educate project in response to the increasing number of teenage pregnancies in Latin America. PCS developed 2 songs and videos, which featured popular teenage singers to serve as role models, to urge abstinence. The songs became instant hits. Since then, PCS has mounted more then 80 major projects in some 40 countries. Highlights of programs range from a successful multi-media family planning campaign in Turkey to humorous television ads in Brazil promoting vasectomy. Recently, PCS initiated projects to teach AIDS awareness. At the core of the enter-educate approach is the social learning theory which holds that much behavior is learned through the observation of role-models. Health professionals work alongside entertainers to produce works that have audience appeal and factual social messages. The enter-educate approach works because it is popular, pervasive, personal, persuasive, and profitable. PCS has found that enter-educate programs pay for themselves through cost sharing and cost recovery.

To examine the relationship between lifestyles and psychosomatic symptoms in children, we conducted a self-administered questionnaire survey of elementary school students and junior high school students in Japan. We designed an original questionnaire to investigate the lifestyles and psychosomatic symptoms of children. In 1997, responses to the questionnaires were elicited from public elementary school fourth grade students (then aged 9-10) and public junior high school seventh grade students (then aged 12-13). The survey was repeated annually for three years as the students advanced through school. For both boys and girls, each cross-sectional analysis revealed a strong relationship between lifestyle behaviors and psychosomatic symptoms. Psychosomatic, symptoms scores varied according to daily hours of sleep, eating of breakfast, having strong likes and dislikes of food, bowel habits, and daily hours of television watching. Both boys and girls with "good" lifestyle, behaviors evaluated by the HPI (Health Practice Index) showed lower scores for psychosomatic symptoms. These findings show that the lifestyle behaviors of children are significantly associated with psychosomatic symptoms and suggest that poor lifestyle behaviors are likely to increase physical and psychological health risks.

The primary purpose of this study was to evaluate if wiki collaboration among Latino high school chemistry students can help reduce the science achievement gap between Latino and White students. The study was a quasi-experimental pre/post control group mixed-methods design. It used three intact sections of a high school chemistry course. The first research question asked if there is a difference in academic achievement between a treatment and control group on selected concepts from the topics of bonding, physical changes, and chemical changes, when Latino high school chemistry students collaborate on a quasi-natural wiki project. Overall results for all three activities (Bonding, Physical Changes, and Chemical Changes) indicated no significant difference between the wiki and control group. However, students performing the chemical changes activity did significantly better than their respective control group. Furthermore, there was a significant association, with large effect size, between group membership and ability to overcome the misconception that aqueous ionic reactants in precipitation reactions exist as molecular pairs of ions. Qualitative analysis of classroom and computer lab dialogue, discussion board communication, student focus groups, teacher interviews, and wiki content attributes the better performance of the chemical changes wiki group to favorable differences in intersubjectivity and calibrated assistance, as well as learning about submicroscopic representations of precipitation reactions in multiple contexts. Furthermore, the nonsignificant result overall points to an aversion to peer editing as a possible cause. Drawing considerably on Vygotsky and Piaget, the results are discussed within the context of how distributed scaffolding facilitated medium levels of cognitive conflict. The second research question asked what the characteristics of distributed metacognitive scaffolding are when Latino high school chemistry students collaborate on a quasi

Diarrhea has great impact on enteral nutrition. The purpose of this review is to identify the factors leading to diarrhea during enteral nutrition and to provide the published updates on diarrhea prevention through nutritional intervention. Diarrhea in enteral fed patients is attributed to multiple factors, including medications (major contributor), infections, bacterial contamination, underlying disease, and enteral feeding. Diet management can alleviate diarrhea in enteral feeding. High content of fermentable oligosaccharides, disaccharides, and monosaccharides and polyols (FODMAPs) in enteral formula is postulated to induce diarrhea and lower FODMAPs formula may reduce the likelihood of diarrhea in enterally fed patients. Fiber-enriched formula can reduce the incidence of diarrhea and produce short-chain fatty acids for colonocytes. Ingesting prebiotics, nonviable probiotics or probiotic derivatives, and human lactoferrin may provide alternatives for reducing/preventing diarrhea. Enteral feeding is not generally considered the primary cause of diarrhea, which is frequently linked to prescribed medications. When diarrhea is apparent, healthcare members should evaluate the possible risk factors and systematically attempt to eliminate the underlying causes of diarrhea before reducing or suspending enteral feeding. Lower FODMAPs formula, prebiotics, probiotic derivatives, and lactoferrin may be used to manage enteral feeding-related diarrhea.

This study examined associations among depression, suicidal behaviors, and bullying and victimization experiences in 1491 high school students using data from the 2009 Youth Risk Behavior Survey. Results demonstrated that depression mediated the association between bullying/victimization and suicide attempts, but differently for males and females. Specifically, depression mediated the link between traditional victimization and suicide attempts similarly across gender, whereas depression mediated the link between cyber victimization and suicide attempts only for females. Similarly, depression mediated the link between traditional bullying and suicide attempts for females only. Depression did not mediate the link between cyberbullying and suicide attempts for either gender. Implications of the findings are discussed, including the importance of greater detection of depression among students involved in bullying, and the need for a suicide prevention and intervention component in anti-bullying programs. Findings suggest that bullying prevention efforts be extended from middle school students to include high school students.

Early atherosclerotic change is found even in childhood, and there is an urgent need to clarify the factors causing childhood atherosclerosis and take preventive measures. Early detection of the contributing risk factors is crucial to facilitate preventive measures. Pulse wave velocity (PWV) is a widely used technique for the assessment of atherosclerosis in children. Lifestyle questionnaire, brachio-ankle PWV (baPWV) and anthropometric data were obtained from junior high school students in an urban area of Japan between 2006 and 2008, from seventh to ninth grades. Mean baPWV increased from 867.4 ± 99.5 m/s to 944.5 ± 117.5 m/s in boys, and from 864.0 ± 99.5 m/s to 923.0 ± 101.3 m/s in girls. Obese students had higher baPWV than non-obese students in both genders across each grade. On logistic regression analysis of ninth grade student data, high baPWV was dependent on systolic blood pressure (SBP), time watching television (TV) and symptoms of depression and anxiety, whereas low baPWV was dependent on time playing video games, light exercise, sleep and indoor play, as well as good friendship and motivation. Systolic blood pressure, time watching TV, and symptoms of depression and anxiety may contribute to arterial stiffness and be related to obesity in junior high school students. © 2017 The Authors Pediatrics International published by John Wiley & Sons Australia, Ltd on behalf of Japan Pediatric Society.

Enteral nutrition is widely used in hospitals as a means of nutritional support and therapy for different diseases. Enteral nutrition must fulfil the energy needs of the body, be balanced by the nutrient composition and meet patient’s nutritional needs. Meat is a source of full-value animal protein, vitamins and minerals. On the basis of this research, recipes and technology for a meat-based enteral nutrition product were developed. The product is a ready-to-eat sterilised mixture in the form of a liquid homogeneous mass, which is of full value in terms of composition and enriched with vitamins and minerals, consists of particles with a size of not more than 0.3 mm and has the modified fat composition and rheological characteristics that are necessary for passage through enteral feeding tubes. The study presents experimental data on the content of the main macro- and micro-nutrients in the developed product. The new product is characterised by a balanced fatty acid composition, which plays an important role in correction of lipid metabolism disorders and protein-energy deficiency, and it is capable of satisfying patients’ daily requirements for vitamins and the main macro- and microelements when consuming 1500-2000 ml. Meat-based enteral nutrition can be used in diets as a standard mixture for effective correction of the energy and anabolic requirements of the body and support of the nutritional status of patients, including those with operated stomach syndrome.

Hypophosphatemia is uncommon in cats, but it has been reported in association with diabetes mellitus and hepatic lipidosis, where it can cause hemolysis, rhabdomyopathy, depression, seizures, and coma. The purpose of this article is to describe 9 cats that developed low serum phosphorus concentrations (alimentation. Serum biochemical analyses from more than 6,000 cats were reviewed. The medical records of all cats with hypophosphatemia were examined for history of enteral alimentation; diabetic cats were excluded from the study. Nine cats, ranging in age from 3 to 17 years, were identified. All cats had normal serum phosphorus concentrations before tube feeding began. Onset of hypophosphatemia occurred 12 to 72 hours after initiation of enteral alimentation, and the nadir for phosphorus concentrations ranged from 0.4 to 2.4 mg/dL. Hemolysis occurred in 6 of the 9 cats. Hypophosphatemia secondary to enteral alimentation is an uncommon clinical finding in cats. Cats with high alanine aminotransferase activity, hyperbilirubinemia, and weight loss should be closely monitored for hypophosphatemia during the first 72 hours of enteral alimentation.

Full Text Available Throughout the United States, many middle and high school students struggle to comprehend science texts for a variety of reasons. Science texts are frequently boring, focused on isolated facts, present too many new concepts at once, and lack the clarity and organization known to improve comprehension. Compounding the problem is that many adolescent readers do not possess effective comprehension strategies, particularly for difficult expository science texts. Some researchers have suggested changing the characteristics of science texts to better assist adolescent readers with understanding, while others have focused on changing the strategies of adolescent readers. In the current paper, we review the literature on selected strategy instruction programs used to improve science text comprehension in middle and high school students and suggest avenues for future research.

This large, population-based study is one of the few to examine prevalence rates of sexual harassment occurring during the past 12 months by victimization and perpetration among adolescents. In this large, cross-sectional survey of students attending 26 high schools, sexual harassment was defined using three questions from the Sexual Experiences Questionnaire. Among 18,090 students completing the survey, 30% disclosed sexual harassment victimization (37% of females, 21% of males) and 8.5% reported perpetration (5% of females, 12% of males). Sexual harassment perpetration was highly correlated with male sex, minority race/ethnicity, same-sex attraction, bullying, alcohol binge drinking, and intraparental partner violence. © The Author(s) 2014.

The purpose of this multi-site qualitative study is to explore how adolescents talk about tobacco use. Sixty-six students in four high schools became co-researchers and led focus group interviews with 205 fellow students. From the interviews, the authors develop a story line that reports how adolescents begin smoking, how smoking becomes a pervasive influence, how attitudes form about smoking, what it means to be a smoker, and, ultimately, student suggestions for tobacco use prevention. Embedded within this story line are complex questions and contradictions. We explore whether peers really are influential, if the media is important, whether smoking is a matter of personal choice, if schools actually promote tobacco use, and whether adolescents can quit smoking.

Recent research has described negative relationship between happiness and habitual smoking among adolescents. No study of this relationship has been conducted among Iranian adolescents. The aim of the present study was to characterize the relationship between happiness and cigarette or hookah smoking among a sample of high school students. A sample of 1,161 10th-grade students in Tabriz (northwest Iran) was selected by multi-stage proportional cluster sampling. Participants completed a self-administered multiple-choice questionnaire including information on cigarette smoking, hookah smoking, happiness score, substance abuse, self-injury, general risk-taking behavior, attitudes towards smoking, socioeconomic information, and demographic characteristics. An ordinal logistic regression model was used for data analysis. It was found that 5.9 and 5.0% of students were regular cigarette smokers and regular hookah smokers, respectively. After controlling for potential confounders, higher happiness scores were found to protect students against more advanced stages of cigarette smoking (odds ratio [OR], 0.98; 95% confidence interval [CI], 0.97 to 0.99; p=0.013). However, no significant relationship was found between happiness scores and hookah smoking status (OR, 1.01; 95% CI, 0.97 to 1.02; p=0.523). Happiness scores were associated with less advanced stages of habitual cigarette smoking among high school students. Our findings underscore the necessity of conducting longitudinal or interventional studies aiming to determine the effects of enhancing happiness on preventing the transition through the stages of cigarette and hookah smoking.

Chronic pancreatitis may lead to steatorrhea, enteric hyperoxaluria, and kidney damage. However, the prevalence and determinants of hyperoxaluria in chronic pancreatitis patients as well as its association with renal function decline have not been investigated.We performed an observational study. Urine oxalate to creatinine ratio was assessed on 2 independent random urine samples in consecutive adult patients with chronic pancreatitis followed at the outpatient clinic from March 1 to October 31, 2012. Baseline characteristics and annual estimated glomerular filtration rate (eGFR) change during follow-up were compared between patients with hyper- and normo-oxaluria.A total of 48 patients with chronic pancreatitis were included. The etiology of the disease was toxic (52%), idiopathic (27%), obstructive (11%), autoimmune (6%), or genetic (4%). Hyperoxaluria (defined as urine oxalate to creatinine ratio >32 mg/g) was found in 23% of patients. Multivariate regression analysis identified clinical steatorrhea, high fecal acid steatocrit, and pancreatic atrophy as independent predictors of hyperoxaluria. Taken together, a combination of clinical steatorrhea, steatocrit level >31%, and pancreatic atrophy was associated with a positive predictive value of 100% for hyperoxaluria. On the contrary, none of the patients with a fecal elastase-1 level >100 μg/g had hyperoxaluria. Longitudinal evolution of eGFR was available in 71% of the patients, with a mean follow-up of 904 days. After adjustment for established determinants of renal function decline (gender, diabetes, bicarbonate level, baseline eGFR, and proteinuria), a urine oxalate to creatinine ratio >32 mg/g was associated with a higher risk of eGFR decline.Hyperoxaluria is highly prevalent in patients with chronic pancreatitis and associated with faster decline in renal function.

Prince William County Public Schools and George Mason University in Virginia, USA, partnered to provide Meaningful Watershed Educational Experiences (MWEEs) for over 25,000 middle and high school students (11-18 year olds) across 34 schools. This school district, situated in a rapidly growing region 55 km southwest of Washington DC, has over 82,000 K-12 students. As native forest cover has been replaced with farming and urbanization, water quality has significantly degraded in the 166,534 km2 Chesapeake Bay watershed. This project was designed to increase student awareness of their impact on the land and waters of the largest estuary in the United States. MWEE is a long-term comprehensive project that incorporates a classroom preparation phase, a hands-on outdoor field investigation, and a reflection and data-sharing component. Training and technical assistance enhances the capacity of teachers of 6th grade, high school Earth Science and Environmental Science to deliver MWEEs which includes schoolyard stewardship, inquiry driven field study, use of hand-held technology and computer based mapping and analysis, project sharing and outreach. George Mason University researchers worked closely with K-12 science educators to create a comprehensive watershed-focused curriculum. Graduate and undergraduate students with strong interests in environmental science and education were trained to deliver the field investigation component of the MWEE. Representative teachers from each school were provided 3 days of professional development and were responsible for the training of their school's science education team. A comprehensive curriculum provided teachers with activities and tools designed to enhance students' mastery of state science objectives. Watershed concepts were used as the unifying theme to support student understanding of curriculum and STEM objectives including: scientific investigation, data collection and communication, chemistry, energy, erosion, human
Balancing extensive ambition and a context overflowing with opportunities and demands: A grounded theory on stress and recovery among highly educated working young women entering male-dominated occupational areas
Full Text Available Several factors underline the issue of stress-related health among young highly educated women. Major societal changes might provide more new challenges with considerably changed and expanded roles than were expected by earlier generations, especially among women. The quantity of young women with higher education has also increased threefold in Sweden in less than two decades and there are a growing number of young women that hereby break with traditional gender positions and enter new occupational areas traditionally dominated by men. The research questions in the present study were: “What is the main concern, regarding stress and recovery, among young highly educated working women breaking with traditional gender positions and entering male-dominated occupational areas?” and “How do they handle this concern?” We conducted open-ended interviews with 20 informants, aged 23–29 years. The results showed that the synergy between highly ambitious individuals and a context overflowing with opportunities and demands ended up in the informants’ constantly striving to find a balance in daily life (main concern. This concern refers to the respondents experiencing a constant overload of ambiguity and that they easily became entangled in a loop of stress and dysfunctional coping behavior, threatening the balance between stress and sufficient recovery. In order to handle this concern, the respondents used different strategies in balancing extensive ambition and a context overflowing with opportunities and demands (core category. This preliminary theoretical model deepens our understanding of how the increasing numbers of highly educated young women face complex living conditions endangering their possibility of maintaining health and work ability.

Our study is the first to describe the prevalence and correlates (demographics, body mass index [BMI], sedentary behaviors, and physical activity) of high school youth who report active videogame playing (active gaming) in a U.S. representative sample. The National Youth Physical Activity and Nutrition Study of 2010 provided data for this study. Active gaming was assessed as the number of days in the 7 days prior to the survey that students in grades 9-12 (14-18 years of age) reported participating in active videogames (e.g., "Wii™ Fit" [Nintendo, Kyoto, Japan], "Dance Dance Revolution" [Konami, Osaka, Japan]). Students reporting ≥1 days were classified as active gamers. Logistic regression was used to examine the association among active gaming and demographic characteristics, BMI, sedentary behaviors, and physical activity. Among 9125 U.S. high school students in grades 9-12 surveyed, 39.9 percent (95 percent confidence interval=37.9 percent, 42.0 percent) reported active gaming. Adjusting for covariates, the following characteristics were positively associated (Pblack, non-Hispanic race/ethnicity; being overweight or obese; watching DVDs >0 hours/day; watching TV >0 hours/day; and meeting guidelines for aerobic and muscle-strengthening physical activity. Four out of 10 U.S. high school students report participating in active gaming. Active gamers tend to spend more time watching DVDs or TV, meet guidelines for physical activity, and/or be overweight or obese compared with nonactive gamers. These findings may serve to provide a baseline to track active gaming in U.S. youth and inform interventions that target sedentary behaviors and/or physical activity.
Full Text Available Background Sleep disorders are prevalent in adolescents and may influence their academic achievement. To date, no study has been done in Indonesia on academic achievement in students with sleep disorders and its related factors. Objective To assess for relationships between academic achievement and related factors, including gender, motivation and learning strategies, IQ level, maternal educational level, socioeconomic status, family structure, after-hours education program, presence of TV/computer in the bedroom, sleep duration during school days, as well as bedtime and wakeup time difference in junior high school students with sleep disorders. Methods This cross-sectional study was performed from January to March 2013. Subjects were students from five junior high schools in Jakarta who fulfilled the criteria for sleep disorders based on the Sleep Disturbance Scale for Children questionnaire. Results There were 111 study subjects. The prevalence of sleep disorders was 39.7%, mostly in difficulties initiating and maintaining sleep (70.2%. Below-average academic achievement was seen in 47.6% of subjects. Factors significantly related to below-average academic achievement were after-hours education program (prevalence ratio 5.6; 95%CI 1.36 to 23.18; P = 0.017, average IQ level (prevalence ratio 3.26; 95%CI 1.38 to 7.71; P = 0.007, and male gender (prevalence ratio 2.68; 95%CI 1.06 to 6.78; P = 0.037. Conclusion Among junior high school students with sleep disorders, factors related to below-average academic achievement are afterhours education program (more than 2 types, the average IQ level, and male gender.

. A key challenge faced by entrepreneurs aiming at starting their “own” high-tech company is the high costs and, thereby, the difficulty of accessing appropriate amount of financing without quickly losing ownership and hence incentive in their business. One possible solution is customer-based financing...... something with a culture, something that permeates the way one thinks of. Educating students in an innovative research environment is key to inspiring them to think commercially. It is in this light, among others, that one should view the advantages of close collaboration between academia and industry...

GeoFORCE Alaska is a four-year, field-based, summer geoscience program designed to raise graduation rates in rural Alaskan high schools, encourage participants to pursue college degrees, and increase the diversity of Alaska's technical workforce. Residents of predominantly Alaska Native villages holding degrees in science, technology, engineering, or math (STEM) bring valuable perspectives to decisions regarding management of cultural and natural resources. However, between 2010 and 2015 the average dropout rate for students in grades 7-12 was 8.5% per year in the North Slope School District and 7% per year in the Northwest Arctic School District. 2015 graduation rates were 70% and 75%, respectively. Statewide statistics highlight the challenge for Alaska Native students. During the 2014-2015 school year alone 37.6% of Alaska Native students dropped out of Alaskan public schools. At the college level, Alaska Native students are underrepresented in University of Alaska Fairbanks (UAF) science departments. Launched in 2012 by UAF in partnership with the longstanding University of Texas at Austin program, GeoFORCE applies the cohort model, leading the same group of high school students on geological field academies during four consecutive summers. Through a combination of active learning, teamwork, and hands-on projects at spectacular geological locations, students gain academic skills and confidence that facilitate high school and college success. To date, GeoFORCE Alaska has recruited two cohorts. 78% of these students identify as Alaska Native, reflecting community demographics. The inaugural cohort of 18 students from the North Slope Borough completed the Fourth-Year Academy in summer 2015. 94% of these students graduated from high school, at least 72% plan to attend college, and 33% will major in geoscience. A second cohort of 34 rising 9th and 10th graders entered the program in 2016. At the request of corporate sponsors, this cohort was recruited from both the

E7, the major transforming protein of high-risk human papillomavirus (HPV), type 16, binds and inactivates the retinoblastoma protein (pRb), and the Rb-related proteins p107 and p130. HPV16 E7 is a nuclear protein lacking a classical basic nuclear localization signal. In this study we investigated the nuclear import of HPV16 E7 oncoprotein in digitonin-permeabilized HeLa cells. HPV16 E7 nuclear import was independent of pRb, as an E7 ΔDLYC variant defective in pRb binding was imported into the nuclei of digitonin-permeabilized cells as efficiently as wild-type E7 in the presence of exogenous cytosol. Interestingly, we discovered that HPV16 E7 is imported into the nuclei via a novel pathway different from those mediated by Kap α2β1 heterodimers, Kap β1, or Kap β2. Nuclear accumulation of E7 required Ran and was not inhibited by the RanG19V-GTP variant, an inhibitor of Kap β mediated import pathways. Together the data suggest that HPV16 E7 translocates through the nuclear pores via a nonclassical Ran-dependent pathway, independent of the main cytosolic Kap β import receptors

Little data are available for sub-Saharan African women on changes in body composition in menopause transition (MT). The study aimed to determine whether there are differences in body adiposity, lean muscle mass, and bone mineral density (BMD) across MT groups in urban African women, who have a high prevalence of obesity and HIV infection, and if this is related to an altered hormonal milieu. Participants were 702 black urban women. Menopause stage was defined using STRAW+10 criteria. Levels of follicle stimulating hormone (FSH), estradiol (E2), dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS), testosterone (T) and sex hormone blinding globulin (SHBG) were measured. Body composition was measured with dual-energy X-ray absorptiometry (DXA) and ultrasound scans. Whole body lean mass (p=0.002) and BMD (pART) correlated negatively with total fat mass (β=-2.92, p=0.008) and total bone mineral content (BMC; β=-78.8, p=0.003). The MT in this population is characterized by lower whole body lean mass and BMD in post- compared to premenopausal subjects but there are minimal differences in fat mass. Lower lean mass and BMD were associated with higher FSH and lower E2 serum levels, respectively. Use of ART was associated with lower fat mass and BMC. Copyright © 2015. Published by Elsevier Inc.

Although stealing among adolescents appears to be fairly common, an assessment of adolescent stealing and its relationship to other behaviors and health issues is incompletely understood. A large sample of high school students (n=3999) was examined using a self-report survey with 153 questions concerning demographic characteristics, stealing behaviors, other health behaviors including substance use, and functioning variables such as grades and violent behavior. The overall prevalence of stealing was 15.2% (95%CI: 14.8–17.0). Twenty-nine (0.72%) students endorsed symptoms consistent with a diagnosis of DSM-IV kleptomania. Poor grades, alcohol and drug use, regular smoking, sadness and hopelessness, and other antisocial behaviors were all significantly (p<.05) associated with any stealing behavior. Stealing appears fairly common among high school students and is associated with a range of potentially addictive and antisocial behaviors. Significant distress and loss of control over this behavior suggests that stealing often has significant associated morbidity. PMID:21389165

While contamination of mobile phones in the hospital has been found to be common in several studies, little information about bacterial abundance on phones used in the community is available. Our aim was to quantitatively determine the bacterial contamination of secondary school students' mobile phones. Altogether 27 mobile phones were studied. The contact plate method and microbial identification using MALDI-TOF mass spectrometer were used for culture studies. Quantitative PCR reaction for detection of universal 16S rRNA, Enterococcus faecalis 16S rRNA and Escherichia coli allantoin permease were performed, and the presence of tetracycline ( tet A, tet B, tet M), erythromycin ( erm B) and sulphonamide ( sul 1) resistance genes was assessed. We found a high median bacterial count on secondary school students' mobile phones (10.5 CFU/cm 2 ) and a median of 17,032 bacterial 16S rRNA gene copies per phone. Potentially pathogenic microbes ( Staphylococcus aureus , Acinetobacter spp. , Pseudomonas spp., Bacillus cereus and Neisseria flavescens ) were found among dominant microbes more often on phones with higher percentage of E. faecalis in total bacterial 16S rRNA. No differences in contamination level or dominating bacterial species between phone owner's gender and between phone types (touch screen/keypad) were found. No antibiotic resistance genes were detected on mobile phone surfaces. Quantitative study methods revealed high level bacterial contamination of secondary school students' mobile phones.

Although the concept of school engagement figures prominently in most school dropout theories, there has been little empirical research conducted on its nature and course and, more importantly, the association with dropout. Information on the natural development of school engagement would greatly benefit those interested in preventing student alienation during adolescence. Using a longitudinal sample of 11,827 French-Canadian high school students, we tested behavioral, affective, cognitive indices of engagement both separately and as a global construct. We then assessed their contribution as prospective predictors of school dropout using factor analysis and structural equation modeling. Global engagement reliably predicted school dropout. Among its three specific dimensions, only behavioral engagement made a significant contribution in the prediction equation. Our findings confirm the robustness of the overall multidimensional construct of school engagement, which reflects both cognitive and psychosocial characteristics, and underscore the importance attributed to basic participation and compliance issues in reliably estimating risk of not completing basic schooling during adolescence.

The aim of this study was to investigate the factors associated with short sleep duration on southern Brazilian high school students. Our study was comprised of 1,132 adolescents aged 14 to 19 years, enrolled in public high schools in São José, Brazil. The students answered a questionnaire about working (work and workload), health perception, smoking, school schedule, sleep (duration and daytime sleepiness), and socio-demographics data. The results showed that more than two thirds of adolescent workers had short sleep duration (76.7%), and those with a higher workload (more than 20 hours) had a shorter sleep duration (7.07 hours) compared to non-workers (7.83 hours). In the analysis of factors associated with short sleep duration, adolescents who worked (OR = 2.12, 95% CI 1.53 to 2.95) were more likely to have short sleep duration compared to those who did not work. In addition, older adolescents (17-19 years) and students with poor sleep quality were 40% and 55% more likely to have short sleep duration compared to younger adolescents (14-16 years) and students with good sleep quality, respectively. Adolescents with daytime sleepiness were more likely to have short sleep duration (OR = 1.49, 95% CI 1.06 to 2.07) compared to those without excessive daytime sleepiness. In addition students of the morning shift (OR = 6.02, 95% CI 4.23 to 8.57) and evening shift (OR = 2.16, 95% CI 1.45 to 3.22) were more likely to have short sleep duration compared to adolescents of the afternoon shift. Thereby adolescents who are workers, older, attended morning and evening classes and have excessive daytime sleepiness showed risk factors for short sleep duration. In this sense, it is pointed out the importance of raising awareness of these risk factors for short sleep duration of students from public schools from São José, located in southern Brazil.

The primary goal of schools is to promote the highest degree of learning possible. Yet teachers spend the majority of their time engaged in lecturing while students spend the majority of their time passively present (Cawelti, 1997, Grinder, 1991; Jackson & Davis, 2000; Jenkins, 1996). Helping students develop proficiency in learning, which translates into using that expertise to construct knowledge in subject domains, is a crucial goal of education. Students need exposure to teaching and learning practices that prepare them for both the classroom and their places in the future workforce (Ettinger, 1998; Longley, Goodchild, Maguire, & Rhind, 2001; NRC, 1996; Texley & Wild, 1996). The purpose of this study was to determine if achievement in high school science courses could be enhanced utilizing mindmapping. The subjects were primarily 9th and 10th graders (n = 147) at a suburban South Texas high school. A pretest-posttest control group design was selected to determine the effects of mindmapping on student achievement as measured by a teacher-developed, panel-validated instrument. Follow-up interviews were conducted with the teacher and a purposive sample of students (n = 7) to determine their perceptions of mindmapping and its effects on teaching and learning. Mindmapping is a strategy for visually displaying large amounts of conceptual, hierarchical information in a concise, organized, and accessible format. Mindmaps arrange information similar to that found on the traditional topic outline into colorful spatial displays that offer the user a view of the "forest" as well as the "trees" (Hyerle, 1996; Wandersee, 1990b). An independent samples t-test and a one-way analysis of covariance (ANCOVA) determined no significant difference in achievement between the groups. The experimental group improved in achievement at least as much as the control group. Several factors may have played a role in the lack of statistically significant results. These factors include the

One rationale for failure to address the needs of high-ability students in schools is that high-ability students do not need special services because they do not face any special problems or challenges. A more extreme corollary of this attitude is the notion that high ability is so protective that students with high ability do not face problems or…

A major barrier to becoming an astronomer is learning how to analyze astronomical data, such as using photometry to compare the brightness of stars. Most fledgling astronomers learn observation, data reduction, and analysis skills through an upper division college class. If the same skills could be taught in an introductory high school astronomy class, then more students would have an opportunity to do authentic science earlier, with implications for how many choose to become astronomers. Several software tools have been developed that can analyze astronomical data ranging from fairly straightforward (AstroImageJ and DS9) to very complex (IRAF and DAOphot). During the summer of 2014, a study was undertaken at Brigham Young University through a Research Experience for Teachers (RET) program to evaluate the effectiveness and ease-of-use of these four software packages. Standard tasks tested included creating a false-color IR image using WISE data in DS9, Adobe Photoshop, and The Gimp; a multi-aperture analyses of variable stars over time using AstroImageJ; creating Spectral Energy Distributions (SEDs) of stars using photometry at multiple wavelengths in AstroImageJ and DS9; and color-magnitude and hydrogen alpha index diagrams for open star clusters using IRAF and DAOphot. Tutorials were then written and combined with screen captures to teach high school astronomy students at Walden School of Liberal Arts in Provo, UT how to perform these same tasks. They analyzed image data using the four software packages, imported it into Microsoft Excel, and created charts using images from BYU's 36-inch telescope at their West Mountain Observatory. The students' attempts to complete these tasks were observed, mentoring was provided, and the students then reported on their experience through a self-reflection essay and concept test. Results indicate that high school astronomy students can successfully complete professional-level astronomy data analyses when given detailed

To examine factors associated with regular physical activity in Croatian adolescents. A cross-sectional survey among high school students was carried out in the 2013/14 school year. A survey was conducted among 33 high schools in Zagreb City, Croatia. Participants were students aged 17-18 years. The dependent variables were regular moderate to vigorous physical activity (MVPA) and overall physical activity measured by the short version of International Physical Activity Questionnaire and defined as 60 min or more of daily physical activity. The independent variables included family, neighborhood, and high school social capital. Other study covariates included: socio-economic status, self-rated health, psychological distress and nutritional status. The associations between physical activity and social capital variables were assessed separately for boys and girls through multiple logistic regression and inverse probability weighting in order to correct for missing data bias. A total of 1689 boys and 1739 girls responded to the survey. A higher percentage of boys reported performing regular vigorous and moderate physical activity (59.4%) and overall physical activity (83.4%), comparing with the girls (35.4% and 70%, respectively). For boys, high family social capital and high informal social control were associated with increased odds of regular MVPA (1.49, 95%CI: 1.18 - 1.90 and 1.26, 95%CI: 1.02 - 1.56, respectively), compared to those with low social capital. For girls, high informal social control was associated with regular overall physical activity (OR 1.38, 95% CI: 1.09 - 1.76). High social capital is associated with regular MVPA in boys and regular overall activity in girls. Intervention and policies that leverage community social capital might serve as an avenue for promotion of physical activity in youth. Copyright © 2016 The Royal Society for Public Health.

The purpose of this study was to clarify the actual sexual behavior and attitudes of high school students in Kitakyushu city, Fukuoka and then to develop effective sex education methods for high school students in this region. This study investigated the sexual behavior and attitudes of 1,297 high school students in Kitakyushu by self-administered questionnaire. The differences in their answers by sex, prevalence of sexual intercourse and change in sexual behavior and attitude before and after the sex education lecture were examined. 39.3% of the students had had sexual intercourse and 74.1% answered that they might have sex, if it were with a partner whom they loved. However, they did not have enough knowledge about contraception and sexually transmitted diseases. This result shows that they did not recognize the risks accompanying sexual intercourse. There are significant differences between male and female students in their sexual attitudes. Male students tend to permit premarital sexual intercourse, unfaithfulness, prostitution, hiring a prostitute and abortion. Male students tend to give more approval to the following opinions: both men and women should agree to sexual contact if the partner wants it; men should take the initiative in sexual contact; women should not talk about sex. Many female students answered that women should make their own decisions to have or not to have sex, however a considerable number of female students answered that for their first intercourse, they just agreed with their partner even though they really did not want to do so. After the sex education lecture, the students have more knowledge about contraception and STDs. However, there is no significant difference in their sexual attitudes before and after the lecture. In order to facilitate more desirable and safer sexual behavior among the younger generation, it is not enough to simply give them knowledge about contraception or STDs, etc. To organize more comprehensive sex

This study addressed a prevalence of low achievement in science courses in an urban school district in Georgia. National leaders and educators have identified the improvement of science proficiency as critical to the future of American industry. The purpose of this study was to examine parent involvement in this school district and its contribution to the academic achievement of successful science students. Social capital theory guided this study by suggesting that students achieve best when investments are made into their academic and social development. A collective case study qualitative research design was used to interview 9 parent participants at 2 elementary schools whose children scored in the exceeds category on the Science CRCT. The research questions focused on what these parents did at home to support their children's academic achievement. Data were collected using a semi-structured interview protocol and analyzed through the categorical aggregation of transcribed interviews. Key findings revealed that the parents invested time and resources in 3 practices: communicating high expectations, supporting and developing key skills, and communicating with teachers. These findings contribute to social change at both the local and community level by creating a starting point for teachers, principals, and district leaders to reexamine the value of parent input in the educational process, and by providing data to support the revision of current parent involvement policies. Possibilities for further study building upon the findings of this study may focus on student perceptions of their parents' parenting as it relates to their science achievement.

Exposure to plasma science among future scientists and engineers is haphazard. In the U.S., plasma science is rare (or absent) in mainstream high school and introductory college physics curricula. As a result, talented students may be drawn to other careers simply due to a lack of awareness of the stimulating science and wide array of fulfilling career opportunities involving plasmas. In the interest of enabling informed decisions about career options, we have initiated an outreach collaboration with the Madison West High School Rocket Club. Rocket Club members regularly exhibit their activities at public venues, including large-scale expos that draw large audiences of all ages. Building on their historical emphasis on small scale rockets with chemical motors, we worked with the group to add a new feature to their exhibit that highlights plasma-based spacecraft propulsion for interplanetary probes. This new exhibit includes a model satellite with a working (low power) plasma thruster. The participating high school students led the development process, to be described, and enthusiastically learned to articulate concepts related to plasma thruster operation and to compare the relative advantages of chemical vs. plasma/electrical propulsion systems for different scenarios.

To examine the prevalence of traditional and Internet bullying and the personal, family, and school environment characteristics of perpetrators and victims. Students (12-14 years old) in 35 junior high schools were randomly selected from the Jerusalem Hebrew (secular and religious) and Arab educational system (n = 2,610). Students answered an anonymous questionnaire, addressing personal, family, and school characteristics. Traditional bullying and Internet bullying for perpetrators and victims were categorized as either occurring at least sometimes during the school year or not occurring. Twenty-eight percent and 8.9 % of students were perpetrators of traditional and Internet bullying, respectively. The respective proportions of victims were 44.9 and 14.4 %. Traditional bullies presented higher Odds Ratios (ORs) for boys, for students with poor social skills (those who had difficulty in making friends, were influenced by peers in their behavior, or were bored), and for those who had poor communication with their parents. Boys and girls were equally likely to be Internet bullies and to use the Internet for communication and making friends. The OR for Internet bullying victims to be Internet bullying perpetrators was 3.70 (95 % confidence interval 2.47-5.55). Victims of traditional bullying felt helpless, and victims of traditional and Internet bullying find school to be a frightening place. There was a higher OR of Internet victimization with reports of loneliness. Traditional bully perpetrators present distinctive characteristics, while Internet perpetrators do not. Victims of traditional and Internet bullying feel fear in school. Tailored interventions are needed to address both types of bullying.

Radiation enteritis is a progressive, disease process that causes intestinal fibrosis and obliterative endarteritis, which results in significant morbidity and mortality. The authors' clinical experience involving 20 patients over a 22-year period from 1967 through 1989 who underwent various surgical procedures to alleviate chronic symptoms secondary to radiation enteritis is described. Eight men and 12 women with a mean age of 52 years (24 to 81 years) underwent a total of 27 procedures for complications of radiation enteritis. Radiation therapy was delivered for treatment of gynecologic malignancies (55%), colorectal cancer (20%), prostate malignancies (10%), and others (15%). The mean average dose of radiation delivered was 5,514 rads with a range of 2,613 to 7,000 rads. The interval from radiation treatment to time of surgery averaged 9 years. Operative procedures consisted of 12 resection and primary anastomosis procedures and 15 resections with stoma creation. Formation of a stoma was used in patients with more severe disease. The 30-day operative mortality was 0% and morbidity was 55%. There were no anastomotic leaks or intra-abdominal abscesses. The authors conclude that resection and primary anastomosis can safely be performed in selected patients but that judicious use of stoma formation can avoid major mortality and morbidity associated with surgery in this setting.

Full Text Available In modern society, patriotism is manifested in all spheres of human life and it is understood as a love for the motherland and its people, as a sense of duty and pride for the country, a sense of honor and personal dignity, personal responsibility for occurring events, devotion to the country and its people. Patriotism is a complex concept including patriotic feelings of an individual. In the article, the peculiarities of the manifestation of patriotic feelings in high school students are analyzed on the basis of the system-functional approach. The study involved a group of senior students of secondary comprehensive school, a group of the representatives of the Ministry of Emergency Situations and cadets of a Cadet Corps. Statistically significant differences in sixteen variables characterizing manifestation of patriotic feelings were obtained in the group of cadets, the differences were observed in degrees of manifestation of both harmonic and inharmonic variables. High values were obtained for the variables of the reflective-evaluative component. The personal difficulties have got higher values which indicates a serious and responsible approach of cadets to the manifestation of patriotic feelings. These results were used to formulate correction programs aimed at the harmonization and development of patriotism among representatives of different age groups

Although cigarette use by adolescents is declining, emerging tobacco products are becoming increasingly popular and youth may use more than one type of tobacco product. The purposes of this study were: (1) to assess patterns of poly-tobacco use among a representative sample of high school students and (2) to determine how beliefs correlate with poly-tobacco use. Data came from the 2013 North Carolina Youth Tobacco Survey (n = 4092). SAS logistic regression survey procedures were used to account for the complex survey design and sampling weights. Among all high school students in NC in 2013, 29.7% reported current any tobacco use, with 19.1% reporting current poly-tobacco use, and 10.6% reporting current use of only one product. Among poly-tobacco users, 59.3% reported that one of the products they currently used was cigarettes. Positive tobacco product beliefs were found to be significantly associated with poly-tobacco use. Communication campaigns, policy efforts, and future research are needed for prevention, regulation, and control of poly-tobacco use among adolescents, which represents a significant public health problem.

Recently, a phenomenon known as sexting, defined here as the transfer of sexually explicit photos via cell phone, has received substantial attention in the U.S. national media. To determine the current and potential future impact of sexting, more information about the behavior and the attitudes and beliefs surrounding it must be gathered, particularly as it relates to sexting by minors. The present study was designed to provide preliminary information about this phenomenon. Participants were 606 high school students (representing 98 % of the available student body) recruited from a single private high school in the southwestern U.S. Nearly 20 % of all participants reported they had ever sent a sexually explicit image of themselves via cell phone while almost twice as many reported that they had ever received a sexually explicit picture via cell phone and, of these, over 25 % indicated that they had forwarded such a picture to others. Of those reporting having sent a sexually explicit cell phone picture, over a third did so despite believing that there could be serious legal and other consequences attached to the behavior. Given the potential legal and psychological risks associated with sexting, it is important for adolescents, parents, school administrators, and even legislators and law enforcement to understand this behavior.
Full Text Available Teaching language is an attractive activity both for the teacher and for the acceptor. They can interact together in this act. Teaching English is a challenge for the teachers to make the students interest in English because as we know English is not the first language for some countries in this world including Indonesia. There are various ways and ideas to teach English so that it can be fun and interest to be taught and to be learnt. But those ways and ideas also should be an up date method and also use a modern technology to be implemented. Along with the development of modern technology, the teachers should involve with it and make it as a part of English teaching tools. Two of the famous and sophisticated tools are computer and the internet. These things have a close relation to be urgent equipment for people. In this article, the writer wants to purpose the use of online games as a way to teach English for junior high school. Te article aims to give another teaching alternative in attracting the junior high school students to learn English in funny and enjoyable way. Through online games they do not only can play the various games but also indirectly they do the exercises of English skills.
Full Text Available This study is one of the first to estimate the impact of “inclusive“ science, technology, engineering, and mathematics (STEM high schools using student-level data. We use multiple statistical strategies to estimate the effect on student achievement from 2 years of attendance at six such high schools in Ohio. The results indicate that two schools had positive effects on science achievement that appear to come at the expense of achievement in social studies. The other schools had negligible or, often, negative effects across both STEM and, particularly, non-STEM subjects. These results are consistent with studies indicating that inclusive STEM schools typically focus on problem-based, personalized learning rather than science and mathematics content. The analysis also reveals the importance of accounting for students’ prior test scores in science, in addition to math and reading, when estimating models that use only 1 year of prior test score data—something that existing studies fail to do.

The lack of a national reproductive biology curriculum leads to critical knowledge gaps in today's high school students' comprehensive understanding of human biology. The Oncofertility Consortium developed curricula that address the basic and clinical aspects of reproductive biology. Launching this academy and creating easy-to-disseminate learning modules allowed other universities to implement similar programs across the country. The expansion of this informal, extracurricular academy on reproductive health from Northwestern University to the University of California, San Diego, Oregon Health & Science University, and the University of Pennsylvania magnifies the scope of scientific learning to students who might not otherwise be exposed to this important information. To assess the experience gained from this curriculum, we polled alumni from the four centers. Data were collected anonymously from de-identified users who elected to self-report on their experiences in their respective reproductive science academy. The alumni survey asked participants to report on their current academic standing, past experiences in the academy, and future academic and career goals. The results of this national survey suggest the national oncofertility academies had a lasting impact on participants and may have contributed to student persistence in scientific learning. © 2016 by the Society for the Study of Reproduction, Inc.

Full Text Available Abstract Background Sleep patterns and habits in high school students in Iran have not been well studied to date. This paper aims to re-address this balance and analyse sleep patterns and habits in Iranian children of high school age. Methods The subjects were 1,420 high school students randomly selected by stratified cluster sampling. This was a self-report study using a questionnaire which included items about usual sleep/wake behaviours over the previous month, such as sleep schedule, falling asleep in class, difficulty falling asleep, tiredness or sleepiness during the day, difficulty getting up in the morning, nightmares, and taking sleeping pills. Results The mean duration of night sleep was 7.7 h, with no difference between girls, boys, and school year (grade. The mean time of waking in the morning was not different between genders. About 9.9% of the girls and 4.6% of the boys perceived their quality of sleep as being bad, and 58% of them reported sleepiness during the day. About 4.2% of the subjects had used medication to enhance sleep. The time of going to bed was associated with grade level and gender. Sleep latency was not associated with gender and grade leve, l and 1.4% experienced bruxism more than four times a week. Conclusion Our results are in contrast with that of previous studies that concluded sleep duration is shorter in Asia than in Europe, that boys woke-up significantly later than girls, and that the frequency of sleep latency category was associated with gender and grade level. The magnitude of the daytime sleepiness, daytime sleepiness during classes, sleep latency, and incidences of waking up at night represent major public health concerns for Iran.

Little research has been conducted that comprehensively examines cyber bullying with a large and diverse sample. The present study examines the prevalence, impact, and differential experience of cyber bullying among a large and diverse sample of middle and high school students (N = 2,186) from a large urban center. The survey examined technology use, cyber bullying behaviors, and the psychosocial impact of bullying and being bullied. About half (49.5%) of students indicated they had been bullied online and 33.7% indicated they had bullied others online. Most bullying was perpetrated by and to friends and participants generally did not tell anyone about the bullying. Participants reported feeling angry, sad, and depressed after being bullied online. Participants bullied others online because it made them feel as though they were funny, popular, and powerful, although many indicated feeling guilty afterward. Greater attention is required to understand and reduce cyber bullying within children's social worlds and with the support of educators and parents.

Promoting Original Scientific Research and Teacher Training Through a High School Science Research Program: A Five Year Retrospective and Analysis of the Impact on Mentored 8th Grade Geoscience Students and the Mentors Themselves
Danch, J. M.
In 2010 a group of 8th grade geoscience students participated in an extracurricular activity allowing them to conduct original scientific research while being mentored by students enrolled in a 3 - year high school Science Research program. Upon entering high school the mentored students themselves enrolled in the Science Research program and continued for 4 years, culminating with their participation in Science Research 4. This allowed them to continue conducting original scientific research, act as mentors to 8th grade geoscience students and to provide teacher training for both middle and high school teachers conducting inquiry-based science lessons. Of the 7 Science Research 4 students participating since 2010, 100% plan on majoring or minoring in a STEM - related field in college and their individual research projects have been been granted over 70 different awards and honors in science fair and symposia including a 3rd and 4th place category awards at two different international science fairs - the International Sustainable Energy Engineering and Environment Project (iSWEEP) and the International Science and Engineering Fair (ISEF). Science Research 4 students developed and conducted a Society for Science and the Public affiliated science fair for middle school students enrolled in an 8th grade honors geoscience program allowing over 100 students from 5 middle schools to present their research and be judged by STEM professionals. Students with research judged in the top 10% were nominated for participation in the National Broadcom MASTERS program which they successfully entered upon further mentoring from the Science Research 4 students. 8th grade enrollment in the Science Research program for 2015 increased by almost 50% with feedback from students, parents and teachers indicating that the mentorship and participation in the 8th grade science fair were factors in increasing interest in continuing authentic scientific research in high school.

Enteral nutrition therapy is common practice in pediatric clinical settings. Often patients will receive a pump-assisted bolus feeding over 30 minutes several times per day using the same enteral feeding set (EFS). This study aims to determine the safest and most efficacious way to handle the EFS between feedings. Three EFS handling techniques were compared through simulation for bacterial growth, nursing time, and supply costs: (1) rinsing the EFS with sterile water after each feeding, (2) refrigerating the EFS between feedings, and (3) using a ready-to-hang (RTH) product maintained at room temperature. Cultures were obtained at baseline, hour 12, and hour 21 of the 24-hour cycle. A time-in-motion analysis was conducted and reported in average number of seconds to complete each procedure. Supply costs were inventoried for 1 month comparing the actual usage to our estimated usage. Of 1080 cultures obtained, the overall bacterial growth rate was 8.7%. The rinse and refrigeration techniques displayed similar bacterial growth (11.4% vs 10.3%, P = .63). The RTH technique displayed the least bacterial growth of any method (4.4%, P = .002). The time analysis in minutes showed the rinse method was the most time-consuming (44.8 ± 2.7) vs refrigeration (35.8 ± 2.6) and RTH (31.08 ± 0.6) ( P refrigerating the EFS between uses is the next most efficacious method for handling the EFS between bolus feeds.

Full Text Available BackgroundThe American Heart Association (AHA has implemented several programs to educate the public about cardiopulmonary resuscitation (CPR. A common issue in bystander CPR is the fear of hurting the victim. As a result, the victim may not receive CPR in time. The purpose of this study was to measure the emotional impact of CPR training on high school students using two approved AHA courses.MethodsA total of 60 students participated in this study. These students had a mean age of 15.4 ± 1.2 years old and were selected from a high school in Southern California. Subjects were divided into two groups, Basic Life Support (BLS (n1 = 31 and Hands-Only™ CPR (n2 = 29. Emotional impacts were assessed by having each subject answer a questionnaire based on given scenarios before and after their training session.ResultsThere was a significant difference in both groups when comparing positive-emotion scores before and after the training (BLS: 30.3 ± 6.0 vs. 34.5 ± 6.7, p < 0.001; Hands-Only 27.9 ± 5.0 vs. 32.1 ± 6.5, p < 0.001. In addition, both groups showed significant reductions in negative-emotion scores (BLS: 29.2 ± 6.7 vs. 23.7 ± 6.5, p < 0.001 and Hands-Only: 26.8 ± 6.1vs. 24.8 ± 7.7, p = 0.05.ConclusionOur results indicate that the AHA programs have positive effects on students’ emotional response. We recommend that future studies include an in-depth study design that probes the complexity of students’ emotions after completing an AHA session.

We administered a self-reporting questionnaire survey regarding the mental health conditions of high school students and attitudes of students and their teachers toward students' mental health issues. In addition, we discussed the requirements for high school students' mental health support system. The subjects were 3,312 students and 208 teachers in four Shizuoka prefectural public high schools in 2009. University Personality Inventory (UPI) is usually conducted to assess university students' mental state and is a questionnaire that high school students can answer easily. Therefore, we adopted UPI for this survey. UPI was composed of 56 unhealthy and 4 healthy condition items. High school students completed the UPI and determined the sum of unhealthy condition items; a higher score indicated a poorer mental health status. The average UPI score of all students (n = 3,312) was 12.7 points, and that of females (n = 1,217)was 15.2 points, which was significantly higher than the 11.3 points of males (n = 2,095). Those with scores > or = 30 points (7.5%), which was more than half of the maximum score, were designated as the High Score (HS) group and considered to have poor mental health. Those with scores of > or = 40 (1.4%) seemed to have very poor mental health, and there was concern that they may be suffering from psychosis. Our observations indicated that HS students were likely to avoid seeking help regarding mental health issues, which was especially true for male HS students. The majority of students chose their friends and parents as advisers, but HS students were significantly more likely to choose advisers who were engaged in jobs related to medical work. Students in both the HS and non-HS groups who did not wish to consult anyone else about their mental conditions wanted to be approached by those around them. High school teachers hesitated to intervene with mentally disturbed students and attempted to resolve problems within the school. Thus, it appears

This case study explores students' physics-related personal epistemologies in school science practices. The school science practices of nine eleventh grade students in a physics class were audio-taped over 6 weeks. The students were also interviewed to find out their ideas on the nature of scientific knowledge after each activity. Analysis of transcripts yielded several epistemological resources that students activated in their school science practice. The findings show that there is inconsistency between students' definitions of scientific theories and their epistemological judgments. Analysis revealed that students used several epistemological resources to decide on the accuracy of their data including accuracy via following the right procedure and accuracy via what the others find. Traditional, formulation-based, physics instruction might have led students to activate naive epistemological resources that prevent them to participate in the practice of science in ways that are more meaningful. Implications for future studies are presented.

Florida International University (FIU), the State University of Florida in Miami is a large enrollment, federally recognized Minority Serving Institution with over 70% of the undergraduate population coming from groups underrepresented in the geoscience workforce. Recruiting local students into the geosciences is challenging because geology is not well integrated into the local school curriculum, the geology is poorly exposed in the low-relief south Florida region and many first generation college students are reluctant to enter unfamiliar fields. We describe and present preliminary findings from Growing Community Roots for the Geosciences in Miami, FL, a 2-year, NSF funded project run by the Department of Earth and Environment at FIU which aims to inform students enrolled in the local middle and high schools to educational and career opportunities in the geosciences. The project takes a multi-faceted approach which includes direct outreach through social media platforms and school visits, a 1-week workshop for middle school teachers and a 2-week summer camp aimed at high school students. An outreach team of undergraduate geoscience majors were recruited to build and maintain informational resources on Facebook, Instagram, Twitter and Google Plus and to accompany FIU faculty on visits to local middle schools and high schools. Both the teacher workshop and the summer camp included lectures on geoscience careers, fundamental concepts of solid earth and atmospheric science, hands on exercises with earth materials, fossils and microscopy, exercises with Google Earth imagery and GIS, and field trips to local geological sites and government facilities. Participants were surveyed at the beginning of the programs on their general educational background in math and science and their general attitudes of and interest in geoscience careers. Post program surveys showed significant increases in the comfort of teaching topics in geoscience among teachers and an increased

Over the past decade STS scholars have been engaged in a continuous dialogue about the performativity of their methods and the interventions of their research practices. A frequently posed question is how STS can make a difference to its fields of study, what John Law has called its different...... 'modes of mattering'. In this paper I explore what difference digital cartography can make to STS practice. I draw on three examples from my own work where digitally mediated maps have entered the conversation and made critical, often surprising, differences to the research process. In my first example...... the map is brought along as an ethnographic device on a piece of fieldwork, in my second example it serves as the central collaborative object in a participatory design project, and in my third example the map becomes the object of contestation as it finds itself centre stage in the controversy...

It is a strong and commonly held belief among nutrition clinicians that enteral nutrition is preferable to parenteral nutrition. We provide a narrative review of more recent studies and technical reviews comparing enteral nutrition with parenteral nutrition. Despite significant weaknesses in the existing data, current literature continues to support the use of enteral nutrition in patients requiring nutrition support, over parenteral nutrition.

Full Text Available The emergence of cooperation among unrelated human subjects is a long-standing conundrum that has been amply studied both theoretically and experimentally. Within the question, a less explored issue relates to the gender dependence of cooperation, which can be traced back to Darwin, who stated that "women are less selfish but men are more competitive". Indeed, gender has been shown to be relevant in several game theoretical paradigms of social cooperativeness, including prisoner's dilemma, snowdrift and ultimatum/dictator games, but there is no consensus as to which gender is more cooperative. We here contribute to this literature by analyzing the role of gender in a repeated Prisoners' Dilemma played by Spanish high-school students in both a square lattice and a heterogeneous network. While the experiment was conducted to shed light on the influence of networks on the emergence of cooperation, we benefit from the availability of a large dataset of more 1200 participants. We applied different standard econometric techniques to this dataset, including Ordinary Least Squares and Linear Probability models including random effects. All our analyses indicate that being male is negatively associated with the level of cooperation, this association being statistically significant at standard levels. We also obtain a gender difference in the level of cooperation when we control for the unobserved heterogeneity of individuals, which indicates that the gender gap in cooperation favoring female students is present after netting out this effect from other socio-demographics factors not controlled for in the experiment, and from gender differences in risk, social and competitive preferences.

Parenting styles are effective in the educational performance of their child. The present study aimed to investigate the relationship between the parenting styles and students' educational performance among Iranian girl high school students. In a cross-sectional survey, female students in high schools of Ilam (Iran) evaluated during the academic year 2014-15. Multistage cluster random sampling was used to select the participants. Data were collected by two demographic and Baumrind's parenting styles questionnaire. The Cronbach's alpha coefficient was measured as an index of internal identicalness of the questionnaire to verify its reliability. A total 400 students were studied. The Mean±SD of the students' age were 14±1.08. The students' school grades were the first year of high school to pre-university course. The Mean±SD of parenting styles were 35.37±5.8, 34.69±6.34 and 19.17±6.64 for permissive parenting style, authoritarian parenting style and authoritative parenting styles, respectively. There was a significant relationship between the score of permissive parenting style (p= 0.001, r= 0.151), authoritarian parenting style (p= 0.001, r= 0.343) and authoritative parenting style (p=0. 001, r= 0.261) with the students' average score for studying. The results of this study demonstrate that parental influence plays an important role in students' educational performance.

In this study, the relationships between student beliefs about the nature of science, student attitudes, and conceptual change about the nature of forces were investigated within a traditional and within a constructivistic high school physics classroom. Students in both classrooms were honors students taking a first year high school physics course and were primarily white and middle to upper SES. Students in the traditional classroom were all high ability juniors, and physics instruction was integrated with pre-calculus. Students in the constructivistic classroom were a mixture of juniors and seniors. Due to the interrelated nature of these factors and the complexity of their interactions, a naturalistic inquiry design was chosen. The data sources included videotape of 7-9 weeks of instruction; analysis of the videotapes using the Secondary Teacher Analysis Matrix (Gallagher & Parker, 1995); field notes; pretest/posttest assessment with the Force Concept Inventory (Hestenes, Wells, & Swackhammer, 1992); student responses from the Views on Science-Technology-Society questionnaire (Aikenhead & Ryan, 1992), the Questionnaire for the Assessment of a Science Course (Chiappetta, 1995), and the Constructivist Learning Environment Survey (Taylor, Fraser, & White, 1994); student interviews; and teacher interviews. In the traditional classroom, (a) students did not think that physics was relevant to everyday experiences; (b) high conceptual change students were more likely to have an angular world view (Cobern, 1993) and have views more similar to the teacher's about the nature of science; and (c) high conceptual change students were able to develop an internally consistent understanding of the content; however, that content appeared to be isolated knowledge in some students. In the constructivistic classroom, (a) students saw physics as relevant and useful; (b) there was no difference in world view or agreement with the teacher's views on the nature of science between high

How teachers manage class learning and interact with students affects students’ motivation and engagement. However, it could be that the effect of students’ representation of teaching quality on the students’ motivation varies between classes. Students from 90 classes participated in the study. We used multilevel random structural equation modeling to analyze whether the relationship of the students’ perception of teaching quality (as an indicator of the students’ mental representation) and students’ motivation varies between classes, and if this variability depends on the class assessment of teaching quality (as an indicator of teaching quality). The effect of teachers’ structure on the regression slope of student perception of student competence was .127. The effect of teachers’ autonomy support on the regression slope of student perception of student autonomy was .066. With this study we contribute a more detailed description of the relationship between teaching quality, competence and autonomy.

Our university course for non-majors (Biology 100) on the neurobiology of drug addiction was recently retooled for delivery at high schools around the state of Washington in order to engage younger students in the study of psychoactive drugs. Many of these students are earning both high school and university credits (dual-enrollment). This paper outlines the course design principles we used to ensure that high school students are earning valid college credits. We present an analysis of learning gains experienced by both university and high school students as measured by before and after course knowledge surveys. We also describe how assessment strategies used for on-campus students have been transferred to our high school partner teachers and how generous interchange and observation ensure that the high school students are engaging deeply in their study of neuroscience. Indeed, many have had a transformative experience that inspires them to contemplate the field of neuroscience as they transition into university study.

Enteral nutrition is the best way to feed or supplement the diet when gastrointestinal tract functions of patients are partially or totally preserved. Whenever total enteral nutrition is needed, it represents the only source of nutrients for patients. Thus, it is mandatory to ensure that high biological value proteins are included in enteral formulae. To assess the biological quality of a protein blend constituted by 50% potassium caseinate, 25% whey protein and 25% pea protein intended to be used in enteral nutrition products. Forty Wistar rats (20 male and 20 female), with initial body weight of 51 g, where divided into four groups and feed for 10 days with: casein (Control), experimental protein blend (Experimental), liophylized normo- and hyperproteic enteral nutrition formulae adapted to the animal nutritional requirements (Normoproteic and Hyperproteic). Protein efficiency ratio (PER), apparent digestibility coefficient (ADC), relationship between retained and absorbed nitrogen (R/A) and relationship between retained and consumed nitrogen (R/I) where calculated. Experimental and control groups had similar values for all analysed indices (PER, ADC, R/A and R/I). These indices where also similar between normo and hyperproteic groups, but lower than experimental and control groups, except in PER, where normoproteic group was either similar to control and hiperproteic group. The quality of the protein blend used in this study is high. It is a good protein source to be used in the development of new enteral nutritional products.

The concept of circles is an ancient concept that has appeared since Ancient Egypt from which this concept gives many significant contributions in mathematics’ development until now. Nevertheless, the concept of circles hides many uncover mysterious features that are of applications in mathematics. One of the mysterious features is the Nine-Point Circle. This Nine-point circle is also known as Euler’s circle, six-point circle, Feuerbach’s circle, the twelve-point circle, and many others. Because of these different names, there have been misunderstand among mathematicians about the Nine-Point Circle’s history. Besides, the discussion of Nine-Point Circle can be used to be an initial material to explain elementary geometry topic in junior high school’s level curriculum of 2013. Therefore, this concept needs to be delivered to the students as a geometry introduction. A possible form of the integration historical aspect of Nine-point circle is suggested in this paper as well as its importance in the curriculum of 2013.

It is widely accepted that students in Japan sleep fewer hours than what they actually need. However, epidemiological data on sleep habits among students are scarce. The sleep habits and related problems among 1650 students in Akita prefecture were studied. The results revealed that schoolchildren attending elementary schools seemed to sleep for a sufficient number of hours, whereas students attending junior or senior high schools were not sleeping enough. In particular, approximately half of the students attending senior high schools answered that they slept 6 h or less on weekdays and nodded off during classes more than twice a week.

When visually impaired students attend regular high school, additional materials are necessary to help them understand physics concepts. The time for teachers to develop teaching materials for such students is scarce. Visually impaired students in regular high school physics classes often use a braille version of the physics textbook. Previously, we evaluated the physics learning environment of a blind high school student in a regular Dutch high school. In this research we evaluate the use of a revised braille textbook, relief drawings and 3D models. The research focussed on the topic of sound in grade 10.

To review the pharmacology, pharmacokinetics, efficacy, and safety of mycophenolate sodium. Primary literature was obtained via a MEDLINE search (1966-June 2003). Abstracts were obtained from the manufacturer and included in the analysis. All studies and abstracts evaluating mycophenolate sodium in solid organ transplantation were considered for inclusion. English-language studies and abstracts were selected for inclusion, but were limited to those consisting of human subjects. Mycophenolate sodium, a mycophenolic acid prodrug, is an inhibitor of T-lymphocyte proliferation. Mycophenolic acid reduces the incidence of acute rejection in renal transplantation. Mycophenolate sodium is enteric coated and has been suggested as a potential method to reduce the gastrointestinal adverse events seen with mycophenolate mofetil. Both mycophenolate mofetil and mycophenolate sodium have been shown to be therapeutically equivalent at decreasing the incidence of allograft rejection and loss. The frequency of adverse events is similar between both compounds, with the most common events being diarrhea and leukopenia. Mycophenolate sodium is effective in preventing acute rejection in renal transplant recipients. At doses of 720 mg twice daily, the efficacy and safety profiles are similar to those of mycophenolate mofetil 1000 mg twice daily. Mycophenolate sodium has been approved in Switzerland; approval in the US is pending.
The newest phase of CERN’s openlab framework was inaugurated this week during a meeting of the openlab partners.

A study was conducted to determine the relationship between the credentials held by science teachers who taught at a school that administered the Science Texas Assessment on Knowledge and Skills (Science TAKS), the state standardized exam in science, at grade 11 and student performance on a state standardized exam in science administered in grade 11. Years of teaching experience, teacher certification type(s), highest degree level held, teacher and school demographic information, and the percentage of students who met the passing standard on the Science TAKS were obtained through a public records request to the Texas Education Agency (TEA) and the State Board for Educator Certification (SBEC). Analysis was performed through the use of canonical correlation analysis and multiple linear regression analysis. The results of the multiple linear regression analysis indicate that a larger percentage of students met the passing standard on the Science TAKS state attended schools in which a large portion of the high school science teachers held post baccalaureate degrees, elementary and physical science certifications, and had 11-20 years of teaching experience.

The objectives of the present study were to identify the association among levels of persistent academic stress, appetite, and dietary habits and to determine the specific types of sweet foods consumed by Korean high-school students according to their academic stress levels. The study participants included 333 high-school students in the 10th to 12th grades in Kyunggi Province, Korea. The level of academic stress was scored with a 75-item academic stress scale and was categorized as high, medium, or low. A food-frequency questionnaire was used to measure the sugar intake from sweet foods. Korean high-school students with a high academic stress level had larger meals than the other students. Compared with students with low academic stress, the students with high academic stress had a higher frequency of sugar intake from the following food types: confectionaries, candies and chocolates, breads, and flavored milk. Moreover, compared with students with low academic stress, the students with high academic stress had a higher total intake of sugar from the following food types: confectionaries, candies, chocolates, flavored milk, traditional Korean beverages, and spicy, sweet, and fried rice cakes. Unhealthy stress-related food choices may compromise high-school students' health and contribute to their morbidity. The findings of the present study could be used to help nutritionists develop effective strategies for nutritional education and counseling to improve adolescent health.

Although enteral nutrition (EN) therapy for Crohn's disease has been confirmed to be as effective as steroid therapy, the precise mechanism responsible for the effects of EN remains unclear, although some of the therapeutic effects of EN are believed to be due to a low dietary fat content. In order to elucidate the influence of fat in EN, it is important to investigate not only the quantity of fat, but also the source of the fat. We compared two enteral nutritional formulae: Elental (Ajinomoto) (elemental diet; ED), which contains only 1.5% fat, provided as long-chain triglycerides (LCT), versus Twinline (Snow Brand Milk Products) (TL), which contains a high percentage of fat (20.4%), provided mainly as medium-chain triglycerides (MCT). These formulae were tested on rat enteritis and rat colitis induced by trinitrobenzene sulfonic acid (TNBS). Both ED and TL reduced the manifestations of enteritis. TL had a stronger anti-inflammatory effect than ED for colitis. TL also had nutritional advantages as compared with ED, as shown by the total serum protein in the TL group being significantly higher than that in the ED group. The results indicate that intraluminal MCT is suitable as a fat energy source during intestinal inflammation in rats. We suggest that Twinline may be more useful to improve nutritional status and to reduce the mucosal inflammation in rat colitis, but that Twinline is equal in effect to Elental for rat enteritis.

Full Text Available The recent spread of technological innovation along with the sophistication of the ICT gadgets have shapped and transformed the realm of learning and teaching including in that of English Language. Alongside, ICT has become more and more inextricable part of human businesses and put a higher level of demand for technological literacy in the part of English learners in order for them to be convident in the digital era membership and participation. This study surveyed 400 high school students as regards: (a their ICT gadgets perceived ownership; (b their day-to-day outside and in-school use and; (c their activities using ICT gadgets for English learning. Findings from the descriptive analyses of the mixed-method study, disclose the positive perception about the gadget ownership. Interestingly, the current study also discovers that there has been a mismatch between the positively perceived ownership of the ICT gadgets and the real day-to-day use as facilitative media for learning, in particular as a useful aids for English language learning. Focusing on the result discussion, issues with regard to discrepancies in the provision of infrastructures and the lack of the support system by school institutions emerge from the FGD analysis highlighting the importance for all decision makers, school institutions, and teachers to consciously start doing something about it. By highlighting the pivotal role of the technology, the researcher suggested a real action for responding to the call for a change in both policy makers and institutonal levels to start integrating the technology into the school curricula.
Full Text Available A term of health-related physical fitness became topical with four its components: aerobic and/or cardiovascular fitness, body composition, abdominal muscle strength and endurance, and lower back and hamstring flexibility. Complex evaluation of health-related physical fitness and physical activity (PA may show a wider insight in health promotion and disease prevention. The aim of this study was to evaluate physical activity relation to health-related physical fitness in Physiotherapy (PT and Physical Education (PE students. Final study sample consisted of 67 students (46 women and 21 men (aged 21.61 ± 0.71. All participants filled in International Physical Activity Questionnaire. Health-related physical testing included: 1 body composition evaluation, 2 abdominal muscles strength tests, 3 dynamometry, 4 hamstring muscles and m. quadratus lumborum elasticity evaluation tests, 5 bicycle ergometer test (anaerobic threshold, maximal oxygen consumption. Results showed that most students had normal body composition parameters (BMI, body fat, muscle mass, body water in both genders and study programs. Women were less physically active that men, and PA duration was higher in PE students. PT students had higher body composition values, lower cardiorespiratory fitness parameters and lower handgrip strength in both hands than PE students. Greater PA generally implies a higher level of health-related physical fitness. PA significantly positively affects body composition, upper m. rectus abdominisstrength, grip strength and aerobic capacity.

Getting students interested in science, specifically in optics and photonics, is a worthwhile challenge. We developed and implemented an outreach campaign that sought to engage high school students in the science of polarized light. We traveled to Montana high schools and presented on the physics of light, the ways that it becomes polarized, how polarization is useful, and how to take pictures with linear polarizers to see polarization. Students took pictures that showed polarization in either a natural setting or a contrived scene. We visited 13 high schools, and presented live to approximately 450 students.

We chose high school students, who are expected to show significant response to education, to try to understand perception and behavior toward irradiated food, and derive evidential materials for education. High school students who had ever acquired information or received education on irradiated food, and students who had ever purchased or eaten irradiated food, tended to have aproper attitude regarding its necessity, safety, and purchase without prejudice. It is necessary to provide information and education to high school students. Additionally, exposure to the irradiated food could be helpful in changing perception and attitude toward irradiated food.

To quote the American Nuclear Society (ANS) Student Constitution, the objective of a student branch is the advancement of science and engineering relating to the atomic nucleus, and of allied science and arts. The Texas A and M University (TAMU) student chapter has extended this objective to that of promoting a better understanding of the nuclear sciences by the general public. The student branch has attempted to reach these objectives by sponsoring a variety of activities designed to motivate and interest individuals to become more aware of nuclear technology and its benefits. These activities are directed toward fellow college students, high school teachers and students, and the surrounding community. One of the largest and most important activities organized by the TAMU student branch is the annual student conference

Up to now, the German agricultural emission inventory used a model for the assessment of methane emissions from enteric fermentation that combined an estimate of the energy and feed requirements as a function of performance parameters and diet composition, with the constant methane conversion rate......, as stated by IPCC. A methane emission model was selected here that is based on German feed data. It was combined with the hitherto applied model describing energy requirements. The emission rates thus calculated deviate from those previously obtained. In the new model, the methane conversion rate is back......-calculated from emission rates and gross energy intake rates. For German conditions of animal performance and diet composition, the national means of methane conversion rates range between 71 kJ MJ(-1) and 61 kJ MJ(-1) for low and high performances (4700 kg animal(-1) a(-1) in 1990 to 7200 kg animal(-1) a(-1...

We report a case of reactive arthritis (ReA) triggered by Yersinia enterocolitica enteritis. A 24-year-old Japanese man developed polyarthritis in the lower limbs. Two weeks prior to these symptoms, he noted diarrhea, right lower abdominal pain and a fever. Y. enterocolitica was not isolated from a stool culture; however, he was diagnosed with ReA based on the colonoscopic findings of a high anti-Y. enterocolitica antibody titer and HLA-B27 antigen positivity. Following treatment with methotrexate and steroids, his arthritis improved. This is the first reported Japanese case of ReA in the English literature after a gastrointestinal infection caused by Y. enterocolitica.

In teaching inquiry to high school students, educators differ on which method of teaching inquiry is more effective: Guided or open inquiry? This paper examines the influence of these two different inquiry learning approaches on the attitudes of Israeli high school biology students toward their inquiry project. The results showed significant differences between the two groups: Open inquiry students were more satisfied and felt they gained benefits from implementing the project to a greater extent than guided inquiry students. On the other hand, regarding documentation throughout the project, guided inquiry students believed that they conducted more documentation, as compared to their open inquiry peers. No significant differences were found regarding `the investment of time', but significant differences were found in the time invested and difficulties which arose concerning the different stages of the inquiry process: Open inquiry students believed they spent more time in the first stages of the project, while guided inquiry students believed they spent more time in writing the final paper. In addition, other differences were found: Open inquiry students felt more involved in their project, and felt a greater sense of cooperation with others, in comparison to guided inquiry students. These findings may help teachers who hesitate to teach open inquiry to implement this method of inquiry; or at least provide their students with the opportunity to be more involved in inquiry projects, and ultimately provide their students with more autonomy, high-order thinking, and a deeper understanding in performing science.
