    While pipeline programs for students from underrepresented minority groups have been established at the high school and college levels, fewer programs have been developed for middle school students. In an effort to reach this cohort, the University of Detroit Mercy School of Dentistry embarked on a grassroots collaborative pipeline program with two distinct segments: Urban Impressions and Dental Imprint. Their purpose is to expose Detroit-area seventh and eighth grade students to careers in dentistry, provide oral health education, and introduce role models. The aim of this pilot study was to determine outcomes for the middle school participants in Urban Impressions (n=86) and Dental Imprint (n=68). Both segments featured hands-on dental activities at the dental school. Outcomes were assessed by pretest-posttest surveys. Across the three cohorts, a total of 86 students participated in one or more sessions, with 57 completing the pre- and post-program surveys, for a 66% response rate. The results showed that the Dental Imprint respondents' knowledge of oral health, dental admissions, and specialties increased by an average 26% over three years. The gain in knowledge for each cohort was statistically significant (pdentistry as a career following the program. These results suggest that the two segments of this program are meeting their goals of increasing middle grade students' awareness of oral health professions including dentistry and providing access to role models. Institutions may benefit from the description of strategies used by this program to address challenges related to establishing early pipeline programs.

    Self-regulated learning requires accurate monitoring and effective regulation of study. Little is known about how effectively younger readers regulate their study. We examined how decisions about which text to restudy affect overall comprehension for seventh-grade students. In addition to a Participant's Choice condition where students were allowed to pick texts for restudy on their own, we compared learning gains in two other conditions in which texts were selected for them. The Test-Based Restudy condition determined text selection using initial test performance - presenting the text with the lowest initial test performance for restudy, thereby circumventing potential problems associated with inaccurate monitoring and ineffective regulation. The Judgement-Based Restudy condition determined text selection using metacognitive judgements of comprehension - presenting the text with the lowest judgement of comprehension, thereby circumventing potential problems associated with ineffective regulation. Four hundred and eighty seventh-grade students participated. Students were randomly assigned to conditions in an experimental design. Gains in comprehension following restudy were larger for the Test-Based Restudy condition than for the Judgement-Based Restudy condition or the Participant's Choice condition. No differences in comprehension were seen between the Judgement-Based Restudy and Participant's Choice conditions. These results suggest seventh graders can systematically use their monitoring to make decisions about what to restudy. However, the results highlight how inaccurate monitoring is one reason why younger students fail to benefit from self-regulated study opportunities. © 2017 The British Psychological Society.

    2011-12-01

    There is great concern over students' poor science achievement in the United States. Due to the lack of science achievement, students are not pursing science related careers resulting in an increase in outsourcing to other countries. Learning strategies such as concept mapping may ameliorate this situation by providing students with tools that encourage meaningful learning. The purpose of this quasi-experimental study was to measure the effects of three concept mapping learning strategies (concept identifying, proposition identifying, student generated) on urban middle school students' understanding of the circulatory system. Three intact classes of seventh-grade students were assigned to one of the three concept mapping strategies. The students were given a pretest on the circulatory system then learned and used their respective concept mapping strategies while learning about the circulatory system. At the conclusion of the study, students' science achievement was measured by performance on an achievement test and rubric scores of their respective concept identifying, proposition identifying, and student generated concept maps. The results of the study suggest that all three of the concept mapping strategies are effective in increasing students' science achievement. Additionally, the moderate significant correlations between the posttest and concept map scores of the current study established that concept maps are a useful measure of student knowledge. Lastly, the results of the current study also suggest that the concept identifying mapping strategy may be a useful scaffold in instructing students how to develop student generated concept maps.

    2014-01-01

    Background In addition to the benefits on physical and mental health, cardiorespiratory fitness has shown to have positive effects on cognition. This study aimed to investigate the relationship between cardiorespiratory fitness and body weight status on academic performance among seventh-grade students. Methods Participants included 1531 grade 7 students (787 male, 744 female), ranging in age from 12 to 14 years (Mage = 12.3 ± 0.60), from 3 different cohorts. Academic performance was measured using the marks students had, at the end of their academic year, in mathematics, language (Portuguese), foreign language (English), and sciences. To assess cardiorespiratory fitness the Progressive Aerobic Cardiovascular Endurance Run, from Fitnessgram, was used as the test battery. The relationship between academic achievement and the independent and combined association of cardiorespiratory fitness/weight status was analysed, using multinomial logistic regression. Results Cardiorespiratory fitness and weight status were independently related with academic achievement. Fit students, compared with unfit students had significantly higher odds for having high academic achievement (OR = 2.29, 95% CI: 1.48-3.55, p academic achievement (OR = 3.65, 95% CI: 1.82-7.34, p academic achievement in seventh-grade students independent of the different cohorts, providing further support that aerobically fit and normal weight students are more likely to have better performance at school regardless of the year that they were born.

    Sargeant, Marcel Andre Almont

    Problem. Science education has long been a great concern in the United States, where less than one-third of the students perform at or above the proficient level. The purpose of this study was to investigate the status of the science program in a selected Union Conference of the Seventh-day Adventist school system. Specifically, this study investigated the perceptions of teachers and students regarding the extent to which the science program meets the criteria of the National Commission on Mathematics and Science Teaching for the 21st century and to what extent these criteria are related to academic performance as indicated by Iowa Test of Basic Skills (ITBS) science scores. Method. Two questionnaires designed by the researcher were used to get responses from 424 students in seventh and eighth grades and 68 teachers to see how this school system compares to the criteria of National Commission on Mathematics and Science Teaching for the 21 st century. Three classroom configurations were investigated in this study, namely: (a) multigrade, (b) two-grade, and (c) single-grade. Crosstabulation, one-way analysis of variance, Kruskal-Wallis test, and linear regression were used to analyze the four research questions of this study. Results. The single-grade classroom configuration received a better rating for the science criteria (p century. Conclusions. The differences in teaching practices explained the discrepancies in the three classroom configurations. Schools can therefore develop policies and strategies to improve the practices in the teaching and learning process in science education that were identified as being deficient by the criteria of National Commission on Mathematics and Science Teaching for the 21st century.

    Roberts, Patrice Helen

    This research was designed to determine the relationships among students' achievement scores on grade-level science content, on science content that was three years above-grade level, on attitudes toward instructional approaches, and learning-styles perceptual preferences when instructional approaches were multisensory versus traditional. The dependent variables for this investigation were scores on achievement posttests and scores on the attitude survey. The independent variables were the instructional strategy and students' perceptual preferences. The sample consisted of 74 educationally oriented seventh-grade students. The Learning Styles Inventory (LSI) (Dunn, Dunn, & Price, 1990) was administered to determine perceptual preferences. The control group was taught seventh-grade and tenth-grade science units using a traditional approach and the experimental group was instructed on the same units using multisensory instructional resources. The Semantic Differential Scale (SDS) (Pizzo, 1981) was administered to reveal attitudinal differences. The traditional unit included oral reading from the textbook, completing outlines, labeling diagrams, and correcting the outlines and diagrams as a class. The multisensory unit included five instructional stations established in different sections of the classroom to allow students to learn by: (a) manipulating Flip Chutes, (b) using Electroboards, (c) assembling Task Cards, (d) playing a kinesthetic Floor Game, and (e) reading an individual Programmed Learning Sequence. Audio tapes and scripts were provided at each location. Students circulated in groups of four from station to station. The data subjected to statistical analyses supported the use of a multisensory, rather than a traditional approach, for teaching science content that is above-grade level. T-tests revealed a positive and significant impact on achievement scores (p < 0.0007). No significance was detected on grade-level achievement nor on the perceptual

    2002-04-01

    The goal of this study was to test the diathesis-stress component of Linville's and Morgan and Janoff-Bulman's models of the relationship between self-complexity and depressive symptoms in a sample of third and seventh grade children (P. W. Linville, 1985, 1987; H. J. Morgan & Janoff-Bulman, 1994). The procedure involved an initial assessment of self-complexity and depressive symptoms. The procedure also involved a follow-up assessment, 10 weeks later, in which depressive symptoms and the occurrence of negative events were assessed. Contrary to hypotheses, neither high levels of total nor positive self-complexity served as a buffer against the onset of depressive symptoms following the occurrence of negative events. In line with hypotheses, however, high levels of negative self-complexity interacted with the occurrence of negative events to predict increases in depressive symptoms in seventh but not third grade children.

    Hill, J P; Holmbeck, G N

    1987-06-01

    Parental reports of disagreements and serious disagreements about rules were examined in 200 families with seventh-grade boys and girls. No gender differences were found: Mothers did not report more disagreements than fathers; no more disagreements were reported for girls than boys. Disagreements about personal habits and family obligations were more common than disagreements about peer relations. Disagreements and serious disagreements, in general, were significantly correlated (positively) with parental reports of child oppositionalism and (negatively) with parents' satisfaction with parenting the target child, although some dyadic differences were found. Children's reports of parental acceptance were negatively correlated with disagreements only for the father-daughter dyad. Support was found for some of Baumrind's ([1968] "Authoritarian vs. Authoritative Control,"Adolescence 3: 255-272) notions regarding relations between rule frequency, child participation in rule making, and disagreements about rules, especially for the father-daughter dyad.

    The trajectory of suicidal ideation across early adolescence may inform the timing of suicide prevention program implementation. This study aimed to identify developmental trajectories of suicidal ideation among an urban cohort of community-residing African Americans (AA) longitudinally followed from middle school through early adulthood (ages 11-19 years). Subtypes based on the developmental course of suicidal ideation from late childhood through mid-adolescence were identified using longitudinal latent class analysis (LLCA) with 581 AA adolescents (52.7% male; 71.1% free or reduced school meals). The developmental trajectories of suicidal ideation were then used to predict suicide attempts in young adulthood. Our LLCA indicated two subtypes (i.e., ideators and nonideators), with 8% of the sample in the ideator class. This trajectory class shows a peak of suicidal ideation in seventh grade and a steady decline in ideation in subsequent grades. Additionally, suicidal ideation trajectories significantly predicted suicide attempt. Results of these analyses suggest the need for suicide prevention approaches prior to high school for AA youth. © 2015 The American Association of Suicidology.

    Full Text Available Our previous research was aimed at psychological underpinnings of the attitude towards conspicuous consumption (displayed through use of designer clothes in high school and university students, aged 17 to 25. This study examined the relationship between the attitude towards designer clothes and social anxiety in 205 sixth and seventh grade primary school children, aged 12 to 13. Their attitude towards designer clothes was assessed by an abridged version of our standard questionnaire (CC - 28. Social anxiety was evaluated by a psychometric scale SA - 34 that was modeled after the social anxiety scale SA - 32 (Tovilović, 2004 in order to comply with our respondents' age and vocabulary. The data indicated that social anxiety at age 12 -13 is primarily manifested as shyness and the importance placed on the impression that one makes on his/her social environment. Both factors were positively correlated with the positive attitude towards designer clothes indicating that among 12 to 13 year old Serbian children wearing designer clothes enhances personal esteem and attractiveness in the eyes of other group members. At this age, the attitude towards designer clothes can be, at least partially, explained by a belief that conspicuous consumption contributes to increased social acceptance and the feelings of personal respect and safety.

    Developing systems thinking skills in school can provide useful tools to deal with a vast amount of medical and health information that may help learners in decision making in their future lives as citizen. Thus, there is a need to develop effective tools that will allow learners to analyze biological systems and organize their knowledge. Here, we examine junior high school students’ systems thinking skills in the context of the human circulatory system. A model was formulated for developing teaching and learning materials and for characterizing students’ systems thinking skills. Specifically, we asked whether seventh grade students, who studied about the human circulatory system, acquired systems thinking skills, and what are the characteristics of those skills? Concept maps were used to characterize students’ systems thinking components and examine possible changes in the students’ knowledge structure. These maps were composed by the students before and following the learning process. The study findings indicate a significant improvement in the students’ ability to recognize the system components and the processes that occur within the system, as well as the relationships between different levels of organization of the system, following the learning process. Thus, following learning students were able to organize the systems’ components and its processes within a framework of relationships, namely the students’ systems thinking skills were improved in the course of learning using the teaching and learning materials.

    A simple answer to the question “Who are Seventh-day Adventists?” can be stated briefly: the Seventh-day Adventist Church (or in Croatia, Christian Adventist Church) is a worldwide body of more than 10 million Christians who observe Saturday as the Sabbath and expect Jesus’ second coming soon. In more detail, one might say that Seventh- day Adventists are a conservative Protestant body of evangelical Christians whose faith is grounded in the Bible and centered on Jesus, with stress on His ato...

    Survival rates were compared among 282 Seventh-day Adventists and 1675 other white female cancer cases following diagnosis during the 30-year period, 1946 to 1976, at two California hospitals owned and operated by the Seventh-day Adventist Church. The Adventist women had a more favorable 5-year relative survival pattern than the other women (69.7% vs. 62.9%) as well as a higher probability of not dying of breast cancer. The differences, however, were no longer significant when stage at diagnosis was taken into account. It seems likely that the lower breast cancer death rates reported among Seventh-day Adventist women as compared with the general population result in part from better survival patterns due to earlier diagnosis and treatment.

    The aim of this research is to investigate if two additional interventions, test and reflection, after standard cardiopulmonary resuscitation (CPR) training facilitate learning by comparing 13-year-old students' practical skills and willingness to act. Seventh grade students in council schools of two municipalities in south-east Sweden. School classes were randomised to CPR training only (O), CPR training with a practical test including feedback (T) or CPR training with reflection and a practical test including feedback (RT). Measures of practical skills and willingness to act in a potential life-threatening situation were studied directly after training and at 6 months using a digital reporting system and a survey. A modified Cardiff test was used to register the practical skills, where scores in each of 12 items resulted in a total score of 12-48 points. The study was conducted in accordance with current European Resuscitation Council guidelines during December 2013 to October 2014. 29 classes for a total of 587 seventh grade students were included in the study. The total score of the modified Cardiff test at 6 months was the primary outcome. Secondary outcomes were the total score directly after training, the 12 individual items of the modified Cardiff test and willingness to act. At 6 months, the T and O groups scored 32 (3.9) and 30 (4.0) points, respectively (ptraining improved the students' acquisition of practical CPR skills. Reflection did not increase further CPR skills. At 6-month follow-up, no intervention effect was found regarding willingness to make a life-saving effort. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  19. A test of the effect of advance organizers and reading ability on seventh-grade science achievement

    Science.gov (United States)

    Underhill, Patricia Annette

    The use of advance organizers was first introduced by Ausubel in his learning theory of meaningful learning. Subsequent research focused on the efficacy of advance organizers. Although, earlier research produced inconclusive results, more recent research suggests advance organizers do facilitate recall. However, the bulk of the research focused on older subjects (students in high school and college and adults). Prior research did not consider that a subject's reading ability may affect the effectiveness of an advance organizer. The purposes of this study were to investigate whether (1) an advance organizer facilitates both immediate and delayed recall, (2) the reading ability of students and the type of pre-instructional material they receive effect recall, and (3) reading ability has an effect on recall with younger students. Seventy-five seventh-grade students were divided into three groups. One group received a written organizer, one group received a graphic organizer, and one group received an introductory passage before reading a learning passage. After completing the reading passage, all subjects received an immediate posttest. Fourteen days later, subjects received the same posttest incorporated in an end-of-the-chapter test. Results of the study indicate the following: (1) no significant difference in immediate and delayed recall of learning material between students who received a written organizer, a graphic organizer, or an introductory passage, (2) there was a main effect for time of testing and a main effect for reading ability, and (3) there was not an interaction between reading ability and the type of pre-instructional material. These findings did not support previous research.

    Norman, Lashaunda Renea

    This qualitative case study investigated the teaching strategies that improve science learning of African American students. This research study further sought the extent the identified teaching strategies that are used to improve African American science learning reflect culturally responsive teaching. Best teaching strategies and culturally responsive teaching have been researched, but there has been minimal research on the impact that both have on science learning, with an emphasis on the African American population. Consequently, the Black-White achievement gap in science persists. The findings revealed the following teaching strategies have a positive impact on African American science learning: (a) lecture-discussion, (b) notetaking, (c) reading strategies, (d) graphic organizers, (e) hands-on activities, (f) laboratory experiences, and (g) cooperative learning. Culturally responsive teaching strategies were evident in the seventh-grade science classrooms observed. Seven themes emerged from this research data: (1) The participating teachers based their research-based teaching strategies used in the classroom on all of the students' learning styles, abilities, attitudes towards science, and motivational levels about learning science, with no emphasis on the African American student population; (2) The participating teachers taught the state content standards simultaneously using the same instructional model daily, incorporating other content areas when possible; (3) The participating African American students believed their seventh-grade science teachers used a variety of teaching strategies to ensure science learning took place, that science learning was fun, and that science learning was engaging; (4) The participating African American students genuinely liked their teacher; (5) The participating African American students revealed high self-efficacy; (6) The African American student participants' parents value education and moved to Success Middle School

    A systems-based classroom intervention on environmental education was designed for seventh grade students; the results were evaluated to see its impact on the development of systems thinking skills and standard science achievement and whether the systems approach is a more effective way to teach environmental issues that are dynamic and complex. A quasi-experimental methodology was used to compare performances of the participants in various dimensions, including systems thinking skills, competence in dynamic environmental problem solving and success in science achievement tests. The same pre-, post- and delayed tests were used with both the comparison and experimental groups in the same public middle school in Istanbul. Classroom activities designed for the comparison group (N = 20) followed the directives of the Science and Technology Curriculum, while the experimental group (N = 22) covered the same subject matter through activities benefiting from systems tools and representations such as behaviour over time graphs, causal loop diagrams, stock-flow structures and hands-on dynamic modelling. After a one-month systems-based instruction, the experimental group demonstrated significantly better systems thinking and dynamic environmental problem solving skills. Achievement in dynamic problem solving was found to be relatively stable over time. However, standard science achievement did not improve at all. This paper focuses on the quantitative analysis of the results, the weaknesses of the curriculum and educational implications.

    1979-05-19

    A comparison of health status between 779 Seventh-day Adventists, who have a strong commitment to heal-related life styles, and two other groups of people--8363 persons referred by general practitioners and 9825 volunteers--was made. The Seventh-day Adventists showed less impairment of systolic and diastolic blood pressures, of plasma cholesterol and plasma urate concentrations, and of lung ventilatory capacity; and less obesity at most specific ages. With increasing age, the level of breathlessness, reported heart disease, hypertension, and hypertensive and diuretic therapy in this sample approached that of the comparative groups, possibly because of natural attrition of high-risk persons in the latter. Depression, sleeplessness, use of sedatives and tranquillizers were lower in the Seventh-day Adventists; although, once again, a drawing together of the three groups in older age categories was evident. It is concluded that the life style of Seventh-day Adventists is conducive to lessened morbidity, delayed mortality, and decreased call on health services in comparison with the general population.

  4. The understandings and meanings eight seventh and eighth grade Latinas gave to science

    Parker, Carolyn Ann

    My study examined the experiences of eight seventh and eighth grade girls of Central American descent, in and out of the science classroom. The study was interpretive in design and explored the question, "How did the eight participants understand and make meaning of science?" Guided by a sociocultural perspective and a socially critical stance, I explored issues of educational access, particularly to science, mediated by the relationships and experiences formed by families, peers, science classrooms, schools, and society. Data sources included monthly individual interviews, regular focus group meetings, school observations, and interviews with teachers and family members. Findings include the importance of school science experiences that emphasize hands-on activities and the study of topics relevant to students' everyday lives. School influences that I discuss include English-as-a-Second Language learning, English language ability and its effect on classroom interactions, ability grouping, standardized testing, and teachers' instructional practices. Out-of-school influences I examine include the national science education reform movement, familial expectations, and society and the media's portrayal of science and the scientist. The implications and recommendations of the study are particularly germane to practice. Recommendations for the science classroom include a continued emphasis on hands-on science experiences that incorporate high academic expectations for all students, including second-language learners. Moreover, curriculum should be connected and relevant to students' everyday experiences. Recommendations for outside-the-science classroom include a thoughtful examination of the educational environment created by a school's tracking policy and continued support of meaningful professional development experiences for teachers. Future research and the subsequent development of theory should include a further analysis of the influence of gender, ethnicity

    Background and purpose . Research in nature of science (NOS) among Asia-Pacific countries such as Singapore is arguably scarce. This study aimed to survey Singaporean secondary school students' views of NOS with a newly developed instrument named Students' Views of Nature of Science (SVNOS), which included various key aspects of NOS that are generally agreed upon by the science education community. Moreover, the relations between some demographic factors, including gender and grade, and students' views of NOS were explored. Sample, design and method In total, 359 Singaporean seventh and eighth graders were invited to participate in this survey. The reliability, validity and structure of the SVNOS instrument were ensured by confirmatory factor analysis. A two-way multivariate analysis of variance was then conducted to determine the interaction effects between the gender variable and the grade-level variable. Results and conclusion The results indicated that the SVNOS instrument is reliable and valid to assess students' views of NOS regarding seven distinct NOS dimensions. The male students were more prone to have constructivist-oriented views of NOS in the most of the SVNOS dimensions, while the female students conveyed more non-objective views of NOS. In addition, the eighth graders revealed more empiricist-oriented views of NOS than the seventh graders in several SVNOS dimensions. This result seems to contradict the results of previous studies that students' views of NOS may reflect a developmental trend with their increasing educational experiences.

    The purpose of this study was to examine relational aggression and its relationship with adverse psychosocial and physical health symptoms among urban, African American youth. Quantitative, cross-sectional survey design. The sample consisted of 185 predominantly African American (95.1%) seventh-grade students (mean age: 13.0; female: 58%) attending 4 urban middle schools. The Children's Social Behavior Scale and Social Experience Questionnaire were used to measure relational aggression and relational victimization. The Pediatric Symptom Checklist was used to assess psychosocial difficulties, including internalizing behaviors, externalizing behaviors, and attention problems. Physical health symptoms were measured with questions about colds/flu, headaches, and stomach aches. 2-way multivariate analysis of variance revealed significant differences in externalizing behavior, with perpetrators reporting higher levels than nonperpetrators. Victims reported more internalizing behavior than nonvictims; however, this was only significant for males. For females, significant negative effects on health outcomes were found, resulting from the interaction of perpetration and victimization. Findings suggest that relational aggression is a common occurrence among urban, minority adolescents and may result in adverse health outcomes. These results provide several avenues for future research and implications for healthcare practice. Intervention strategies are needed to prevent relational aggression and continual or subsequent adverse health symptoms.

    Hinds, Beverley Fiona

    The purpose of this qualitative study was to determine what inspires or leads seventh-grade African-American girls toward an interest in STEM, to characterize and describe the context of an out-of-school STEM learning environment, explore the impact on the seventh- grade African-American girls who participated in the program as it relates to individual STEM identity, and identify personal and academic experiences of seventh-grade African- American girls that contribute to the discouragement or pursuit of science and math-related academic pathways and careers. Notable findings in this study included the following: 1. Participants were interested in STEM and able to identify both external and internal influences that supported their involvement and interest in STEM activities. External influences expanded and elevated exposure to STEM experiences. 2. The MJS program provided an opportunity for participants to overcome challenges related to science and math knowledge and skills in school. 3. The MJS program increased levels of interest in STEM for the participants. 4. All participants increased their capacity to demonstrate increased knowledge in STEM content as a result of the learning experiences within the MJS program, and participants transferred this knowledge to experiences outside of the program including school. 5. The STEM learning environment provided multiple opportunities for participants to meet high expectation and access to engaging activities within a supportive, well-managed setting. 6. The MJS program participants demonstrated behaviors related to building a STEM identity through the components described by Carlone and Johnson (2007), including recognition-internal and external acknowledgement of being a STEM person; competence-demonstrating an understanding of STEM content; and performance-publically exhibiting STEM knowledge and skills. The findings in this study suggested that African-American seventh-grade girls interested in STEM are inspired

    Mahomed-Asmail, Faheema; Swanepoel, De Wet; Eikelboom, Robert H

    2016-05-01

    This study aimed to describe the prevalence and characteristics of hearing loss in school-aged children in an urban South African population. Children from grade one to three from five schools in the Gauteng Province of South Africa formed a representative sample for this study. All children underwent otoscopic examinations, tympanometry and pure tone screening (25dB HL at 1, 2 and 4kHz). Children who failed the screening test and 5% of those who passed the screening test underwent diagnostic audiometry. A total of 1070 children were screened. Otoscopic examinations revealed that a total of 6.6% ears had cerumen and 7.5% of ears presented with a type-B tympanogram. 24 children (12 male, 12 female) were diagnosed with hearing loss. The overall prevalence of hearing loss was 2.2% with Caucasian children being 2.9 times more (95% confidence interval, 1.2-6.9) likely to have a hearing loss than African children. Hearing loss prevalence in urban South African school-aged children suggest that many children (2.2%) are in need of some form of follow-up services, most for medical intervention (1.2%) with a smaller population requiring audiological intervention (0.4%).

    Nobel, Michele Mcmahon

    2005-07-01

    This study investigated the effects of classwide peer tutoring (CWPT) on the acquisition, maintenance, and generalization of science vocabulary words and definitions. Participants were 14 seventh grade students at-risk for failure in a general education science course; 3 students had learning disabilities and 2 had a communication disorder. CWPT was conducted daily for 20 minutes during the last period of the school day. Procedures for CWPT were consistent with the Ohio State University CWPT model. Students were engaged in dyadic, reciprocal tutoring. Tutors presented word cards to tutees to identify the word and definition. Tutors praised correct responses and used a correction procedure for incorrect responses. After practicing their vocabulary words, students completed a daily testing procedure and recorded and plotted data. Many of the study's findings are consistent with previous studies using CWPT to teach word identification. Results of this study indicate a functional relationship between CWPT and acquisition of science vocabulary. All students were able to acquire words and definitions. Results for maintenance and generalization varied. When acquisition criterion was changed, maintenance and generalization scores increased for some students, while other students remained consistently high. All students reported that they enjoyed CWPT, and all but student stated it helped them learn science vocabulary.

    1998-04-01

    In 1995, a survey was conducted among students attending 69 Seventh-day Adventist (SDA) high schools within the United States and Canada. The survey assessed the extent that these students practiced sexual and drug-use behaviors which place them at risk for contracting or transmitting the human immunodeficiency virus (HIV). A total of 1,748 respondents enrolled in grades 9 through 12 completed questionnaires similar to the instrument used in the 1993 Youth Risk Behavior Survey (YRBS). Data were collected and compared to results from the 1993 YRBS. Students who attended SDA parochial schools reported lower rates of sexual intercourse compared to YRBS school counterparts (16.3% vs. 53.1%) and lower rates of all substances measured. Furthermore, respondents were more likely to engage in substance use and sexual intercourse if they had at least one parent who used tobacco, alcohol, or marijuana, as reported by the students.

  17. The effect of outdoor environmental education on in-class behaviors of sixth, seventh and eighth grade students

    Science.gov (United States)

    Cumberbatch, Albert R.

    Does the natural environment enhance positive human behaviors, behaviors which meet societal expectations? If that is the case, at what level of our social development does exposure and involvement with nature become a prerequisite? This study sought to discover an answer to the first question through examination of a small public school sample. The second will have to await future study. Public schools, while making some token response to the rising environmental consciousness, have failed or completely ignored environmental education. This study focuses on using the natural environment as a classroom with an environmental education curriculum. The control was academic grades before the environmental education class. The independent variable was academic grades after environmental education. Comparisons of academic conduct grades between classes taken before and after environmental education were made. Three environmental education classes comprising ninety students were evaluated. The mean of all classes was calculated. Results indicate that there is a positive behavioral correlation between environment education and academic classes. However, there were many uncontrolled variables which necessitate further study. One example is the arbitrary standard among teachers for evaluating conduct grades. Conduct grades can also be subjective. In further studies, a standardized tool for evaluating conduct grades would be essential.

    2006-03-01

    Full Text Available Since etching is completed at the same stage as priming and bonding, when applying the sixth and seventh generation bonding, the exposed smear layers are constantly surrounded by primer and bonding and cannot collapse. The smear layer and the depth of penetration of resin bonding in dentinal tubules are completely integrated into hybrid layer. The purpose of this laboratory research was to study the penetration depth of two self etching adhesive. Fourteen samples of human extracted teeth were divided into two groups. Each groups consisted of seven samples, each of them was treated with sixth generation bonding agent and the other was treated with seventh generation bonding agent. The results disclosed that the penetration into dentinal tubules of seventh generation bonding agent was deeper than sixth generation bonding agent. Conclusion: bond strength will improve due to the increasing of penetration depth of resin bonding in dentinal tubules.

  2. Environmental literacy of Hispanic, urban, middle school students in Houston, Texas

    Science.gov (United States)

    Meuth, Amber M.

    With the global crises facing the planet that bring major implications, (Hart & Nolan, 1999; Hungerford & Simmons, 2003) it is imperative that there be an environmentally literate citizenry who can identify, solve, and prevent environmental issues. Since middle school students are evolving into participating citizens and are developing the ability to think in abstract terms, they are a critical group to study regarding levels of environmental literacy. Additionally, with the increased resource needs and decreased air and water quality in highly populated urban areas, focusing on the environmental literacy of students living and attending school in urban areas is essential. The purpose of this study was to describe the levels of environmental literacy of a group of Hispanic, urban, middle school students in Houston, Texas. Sixth, seventh, and eighth grade students who attend a charter school in Houston, Texas were given, the Middle School Environmental Literacy Survey (MSELS). This survey has been developed to measure components of environmental literacy as related to domains identified critical to environmental literacy (McBeth et al., 2008). The four domains include ecological knowledge, environmental affect, cognitive skills, and behavior. Data collected from the survey was used to determine levels of environmental literacy in the following variables: ecological knowledge, verbal commitment, actual commitment, environmental sensitivity, general environmental feelings, and environmental issue and action skills. Descriptive statistics were calculated and analyzed for each grade level and as an entire sample for each variable in order to generate a profile of the group. Composite scores were calculated in the four domains (ecological knowledge, environmental affect, cognitive skills, and behavior) and were compared to high, moderate, and low levels of environmental literacy set forth by top environmental education researchers (McBeth et al., 2008). Additionally, two

    American Seventh-day Adventists have been reported to have lower cancer mortality and incidence than the general population. Adventists do not consume tobacco, alcohol or pork, and many adhere to a lacto-ovo-vegetarian lifestyle. Baptists discourage excessive use of alcohol and tobacco. In this study, we investigated whether the incidence of cancer in a large cohort of Danish Adventists and Baptists was different compared to the general Danish population. We followed 11,580 Danish Adventists and Baptists in the nationwide Danish Cancer Registry, which contains information on cases of cancer for 1943-2008. Cancer incidence in the cohort was compared with that in the general Danish population as standardized incidence ratios (SIRs) with 95% confidence intervals (CIs), and within-cohort comparisons were made with a Cox model. Lower cancer incidences were observed for both Seventh-day Adventist men (SIR, 66; 95% CI, 60-72) and women (85; 80-91). The same result was observed for Baptists although not as low. The differences were most pronounced for smoking-related cancers such as those of the buccal cavity and lung (SIR, 20; 13-30 for Seventh-day Adventist men and 33; 22-49 for Seventh-day Adventist women). The incidences of other lifestyle-related cancers, such as of stomach, rectum, liver and cervix, were also decreased. In general, the SIRs were lower for men than for women, and Adventists had lower hazard rates than Baptists. Our findings point to the benefits of compliance with public health recommendations and indicate that lifestyle changes in the population might change the cancer risks of individuals.

  7. Role of life-style and dietary habits in risk of cancer among seventh-day adventists.

    Science.gov (United States)

    Phillips, R L

    1975-11-01

    The Seventh-Day Adventist population abstains from smoking and drinking; about 50% follow a lacto-ovo-vegetarian diet; and most avoid the use of coffee, tea, hot condiments, and spices. Existing data on cancer mortality in Seventh-Day Adventists clearly document mortality rates that are 50 to 70% of general population rates for most cancer sites that are unrelated to smoking and drinking. Several approaches to determining whether this reduced risk is due to the unique Seventh-Day Adventist life-style or selective factors related to who choses to become and remain a Seventh-Day Adventist are described. A comparison of the mortality experience of Seventh-Day Adventist and non-Seventh-Day Adventist physicians shows equal cancer mortality, which is consistent with the hypothesis that the apparent reduced risk of cancer death in all Adventists may be due to selective factors. However, the results of a small case-control study of colon and breast cancer among Adventists show statistically significant relative risks for colon cancer of 2.8 for past use of meat. For current food use, the significant relative risks are 2.3 for beef, 2.7 for lamb, and 2.1 for a combined group og highly saturated fat foods. This strongly suggests that the lacto-ovo-vegetarian diet may protect against colon cancer. However, the evidence linking diet to breast cancer is less clear. Because of the marked variability in dietary habits within the Seventh-Day Adventist population, they will be a productive group for further study of diet and cancer.

  8. Seventh annual report of RADMIL 1991/92

    International Nuclear Information System (INIS)

    1992-01-01

    RADMIL began its programme of monitoring of radiation and radioactivity in Lancashire in 1985. This is RADMIL's seventh annual report and thirteenth report in a series of reports on the Lancashire environment. Two [1,2] are specific to the consequences of the Chernobyl accident on Lancashire, six annual reports [3,4,5,6,7,8] detail the results of programmed radiation and radioactivity monitoring in Lancashire, two reports are specific to radon in Lancashire homes [9,10]. One reports on external dose-rates in the intertidal areas of the rivers Lune, Ribble and Wyre [11] and one report describes monitoring of the Ribble up to November 1991 [12]. This seventh report follows the established presentation, except that RADMIL's sixth annual report (1990/91) described in one section the monitoring of the Rivers Ribble and Wyre. The corresponding section of the seventh annual report concentrates on the River Ribble only. Both rivers are affected by Sellafield effluents, but only the Ribble is affected to any significant extent by Springfields effluents. RADMIL monitoring of Wyre was increased during 1990/91 and in the light of the conclusions reached, the monitoring has been decreased in 1991/92. However, to gain more information about the River Ribble, that area of monitoring has increased in 1991/92 and is described in a section with the River Ribble only. Because of the increased concern about contamination of the river, the report also includes the period 31/3/92 (year end) to 31/8/92 (the time of report production). In this respect the report is current and presents RADMIL's up-to-date' description of River Ribble contamination. (Author)

    Background: There are several factors that influence teaching urban physical education. Violence, poverty and irrelevant curricula influence the teaching-learning environment in urban physical education. One approach to urban physical education is to look carefully at the ecology that exists within an urban physical education class. This ecology…

  11. Cancer morbidity and mortality in USA Mormons and Seventh-day Adventists.

    Comparison of cancer morbidity and mortality rates between Mormons and Seventh-day-Adventists and the corresponding rates in the Federal Republic of Germany and the United States, reveals that mortality from malignant neoplasms in general is much lower in Mormons and Seventh-day Adventists than in the Federal Republic of Germany. The difference concerns in particular the tobacco-dependent tumors: compared to the rate of affected males in the Federal Republic of Germany, only some 25% of Mormon males are getting lung cancer. Similar patterns are found in laryngeal carcinoma. Tumors that are related to both alcohol and tobacco, such as carcinomas of tongue, pharynx and esophagus, are also significantly less frequent in Mormons. Malignant neoplasms of the female genital tract show distinct analogies: cervical carcinoma has a morbidity rate of only 26.7% of affected women in Germany. Accordingly, mortality rates of Mormons and Seventh-day Adventists show a significant lower level when compared with cancer data of lung, colon and rectum, and prostate from the best German cancer registry (Saarland). Some tumor rates are higher in Mormons, e.g. malignant melanoma, also all types of malignant lymphoma and myeloma. The life expectancy is generally elevated by 2-4 years in Mormons and Seventh-day Adventists. The association with the particular life style of both religious groups, especially the strict reduction of tobacco consumption, and factors of dietary and other habits is discussed.

    2010-09-01

    Full Text Available The relations of students achievement and motivation for involvement in PE classes were examined in a sample of 247 seventh-grade elementary school students of both sexes. The independent variables in the study were: sex, general success of the previous grade, PE grade, students’ opinion on sufficiency of knowledge acquired through instruction process, students’ involvement in sport. The scale for measurement of motivation consisted of 29 items obtained by adaptation of the Scale for measurement of motives of sports’ achievement. Correlation analysis, multiple regression analysis and chi square test were preformed. It was established that male students manifested higher motivation that the females. The assumptions: that females will have better PE grades that the male students; that students’ success was negatively related to involvement in sport; that PE grade was connected to involvement in sport; that general success was negatively related to students’ involvement in PE and that PE grade is positively related to students’ motivation for involvement in instruction, were not confirmed.

    Full Text Available Objectives: The aim of the study was to compare the effect of fifth and seventh generation bonding agent on sealant success.Materials and Methods: Sixty-four school children aged six to nine years received sealants in four permanent molars in a split mouth design, such that each patient received sealant in the first permanent molar with fifth generation bonding agent in one arch and seventh generation bonding agent in the other arch; contra-lateral molars were sealed with sealant alone. The evaluation was carried out at baseline, three months, six months and 12 months, according to the criteria by Feigal et al, in 2000. Chi- square test was used to analyze data at P<0.05 level of significance.Results: Statistically significant differences were found for sealant retention between fifth generation and sealant group, and fifth generation and seventh generation groups; whereas, no significant difference was found for sealant retention between seventh generation and sealant group at three, six and 12 months.Conclusion: As separate etch and rinse steps are not required for seventh generation bonding agents, and almost similar results were obtained for both sealant and seventh generation groups, it can be concluded that application of sealant along with a seventh generation bonding agent may enhance sealant success and can be used for caries prevention in preventive programs.Key words:  Pit and Fissure Sealants; Dental Caries; Adhesives

  14. The Relationship between Parental Behaviors and Children's Sugary Drink Consumption Is Moderated by a Television in the Child's Bedroom.

    The aim of this longitudinal study was to examine the link between perceived authoritative parenting behaviors and sugary drink consumption among children from low-income families who do or do not have televisions (TVs) in their bedrooms. Middle school students (N = 480) completed a baseline survey in sixth grade and a follow-up survey in seventh grade. The students were recruited from 12 schools in a low-income, predominantly black (33%) and Latino (48%), urban school district. The survey assessed the children's perception of their parents' controlling and nurturing behaviors, the presence of a TV in their bedrooms, and their level of sugary drink consumption on the previous school day. Children's report of specific controlling and nurturing parental behaviors were used to create an "authoritative parenting" score. Regression analyses were used to test the main and interactive effects of authoritative parenting behaviors and having a TV in the bedroom with sugary drink consumption in seventh grade, controlling for age, race/ethnicity, gender, BMI, and sugary drink consumption in sixth grade. A significant interaction emerged: The authoritative parenting score predicted lower levels of sugary drink consumption in seventh grade, but this relationship was moderated by whether or not there was a TV in the child's bedroom. A TV in the child's bedroom may weaken the positive influence of authoritative parenting behaviors on limiting sugary drink consumption among middle school children from low-income families. Stronger initiatives are recommended to educate parents and help them refrain from placing TVs in their children's bedrooms.

    The standardized mortality ratio (SMR) was studied in Norwegian Seventh-Day Adventists, a religious group practising a life-style regarded as protective against cancer and cardiovascular disease. Persons converting before the age of 19 had a SMR of 69 (men) and 59 (women). This was both significantly lower than the general population and those converting at age 35 or above. The site mainly responsible for the low SMR in young converts was cardiovascular disease (men, 44; women, 52). Overall SMR in Seventh-Day Adventists compared to the general population was 82 (95% CI: 77-88, p less than 0.001) in men and 95 (95% CI: 91-100, NS) in women. SMR for cancer was significantly lower only in men before the age of 75 (SMR: 78, 95% CI: 61-99, p less than 0.05). Adopting a healthful lifestyle early in life seems to be of decisive importance with regard to mortality, later lifestyle changes have a smaller effect on death risk.

    1958-10-01

    A study was made of the incidence of certain types of disease among Seventh-day Adventists, a religious group of special interest because they refrain from smoking and drinking. Epidermoid cancer of the lung, previously shown to be related to smoking, was 10 times less common among Seventh-day Adventists than among the general population, even among those Seventh-day Adventists living in the Los Angeles area where all are exposed to smog. Similarly, cancers of the mouth, larynx, and esophagus, previously shown to be related not only to smoking but also to heavy drinking, were at least 10 times less common among Seventh-day Adventist men than among men of the general population. All other types of cancer, with the exception of cancer of the bladder and cervix, occurred among Seventh-day Adventists with the same frequency as in the general population. The latter occurred slightly less than in the general population. Myocardial infarction in Seventh-day Adventist males was less frequent and occurred at a later age than among males in the general population; while the age distribution of the disease among the Seventh-day Adventist females was similar to that of females in the general population.

    Full Text Available Mauch, MacCallum, Levy, and Leroi (2015 carried out a large-scale study of changes in American popular music between 1960 and 2010. Using signal processing methods, they found evidence suggesting a decreasing use of the dominant seventh chord and increasing use of the minor-minor seventh chord. While signal analysis methods have improved substantially in recent years, the accuracy of signal-based analysis remains imperfect. Using a contrasting method and independent musical sample, this paper reports converging evidence replicating these findings.

    To examine whether generation of 'socially appropriate' responses or divergent responses to continued peer pressure is a more effective deterrent of actual delinquency. The sample of 129 urban adolescents included both boys and girls (51.9% male) and was predominantly black (48.%) and Hispanic (28.7%). They were studied longitudinally from seventh to eighth grade in New York City from 2000-2001. Resistance strategies to offers to smoke and to shoplift were assessed in two separate videotaped role-plays. Socially appropriate responses were defined as assertive and nonaggressive, including the use of a simple no; direct, declarative statements; and offering prosocial alternatives. Divergent responses were defined as multiple unique response types within the same situation regardless of appropriateness. Data were analyzed using hierarchical logistic regressions. High use of divergent responses was consistently associated favorably with changes in delinquency from seventh to eighth grade. High use of divergent responses was associated with lowered likelihood to vandalize, steal or shoplift, and commit multiple acts of any type of delinquency, even after controlling for seventh grade delinquency. Socially appropriate responses showed little association to any delinquent behavior. Different social pressure situations and contexts may require different responses. As trying to teach effective responses for every single potential peer pressure situation would be impossible, promoting divergent thinking may be an attractive alternative.

    MoEDAL is the LHC’s newly approved seventh experiment. Unlike its general-purpose partners installed along the LHC ring, MoEDAL will search for very specific exotic objects such as the highly ionizing magnetic monopoles and massive, conventionally charged, supersymmetric particles. The experiment is relatively small, cheap and quick to install but its physics potential is huge and a true complement to the already wide exploration range of the LHC experiments.   MoEDAL collaborators install the first layers of plastic in the LHCb VELO cavern at LHC Point 8. In its final configuration, MoEDAL will consist of ten layers of plastic attached to the walls and ceiling of the cavern that houses the VELO detector of LHCb at Point 8 of the LHC ring. “When a heavily ionizing stable particle, such as a magnetic monopole or a massive stable super-symmetric particle, crosses the MoEDAL detectors, it produces damage in the plastic at the level of polymeric bounds in a small...

    The International Conference on Time-Resolved Vibrational Spectroscopy (TRVS) is widely recognized as the major international forum for the discussion of advances in this rapidly growing field. The 1995 conference was the seventh in a series that began at Lake Placid, New York, 1982. Santa Fe, New Mexico, was the site of the Seventh International Conference on Time-Resolved Vibrational Spectroscopy, held from June 11 to 16, 1995. TRVS-7 was attended by 157 participants from 16 countries and 85 institutions, and research ranging across the full breadth of the field of time-resolved vibrational spectroscopy was presented. Advances in both experimental capabilities for time-resolved vibrational measurements and in theoretical descriptions of time-resolved vibrational methods continue to occur, and several sessions of the conference were devoted to discussion of these advances and the associated new directions in TRVS. Continuing the interdisciplinary tradition of the TRVS meetings, applications of time-resolved vibrational methods to problems in physics, biology, materials science, and chemistry comprised a large portion of the papers presented at the conference.

    Objective: To determine the factors related to tobacco smoking among students of grade 6-10 in an urban setting in Sindh, Pakistan. Study Design: Cross-sectional survey. Place and Duration of Study: The study was conducted in public and private schools of Hyderabad, Sindh, Pakistan, from January 2008 to June 2009. Methodology: A sample of 501 students from grade 6-10 were selected through simple random sampling and probability proportional to size. Students answered to a pre-tested questionnaire on socio demography and tobacco use. Descriptive statistics were used to determine frequency distribution. Results: About 9% of the students were smoking some form of tobacco. Ten percent had tried cigarette smoking and about 80% and 61% were chewing Areca nuts and 'Paan' (concoction of Areca nuts, tobacco, hydrated lime, herbs and spices wrapped in betel leaf. Being old, male gender, peer influence, personal attitude toward future smoking, chewing 'Gutka' (concoction of tobacco, Areca nuts and hydrated lime) and having a more educated mother was associated with greater frequency of smoking any form of tobacco. Conclusion: High frequency of tobacco smoking, the attitude toward tobacco consumption and a very high consumption of Areca nuts and other chewable tobacco products by the children warrants urgent action in order to control the tobacco epidemic in Pakistan.

    Polycystic ovary syndrome (PCOS) has become increasingly common over recent years and is associated with reproductive features as well as cardiometabolic risk factors, including visceral obesity, dyslipidemia and impaired glucose homeostasis, and potentially cardiovascular disease. Emerging evidence suggests that these long-term metabolic effects are linked to a low-grade chronic inflammatory state with the triad of hyperinsulinemia, hyperandrogenism, and low-grade inflammation acting together in a vicious cycle in the pathophysiology of PCOS. Dysregulation of the sympathetic nervous system may also act as an important component, potentially creating a tetrad in the pathophysiology of PCOS. The aim of this review is to examine the role of chronic inflammation and the sympathetic nervous system in the development of obesity and PCOS and review potential therapeutic options to alleviate low-grade inflammation in this setting.

  17. Cancer incidence in Norwegian Seventh-Day Adventists 1961 to 1986. Is the cancer-life-style association overestimated?

    Science.gov (United States)

    Fønnebø, V; Helseth, A

    1991-08-01

    Standardized incidence ratio for cancer in Norwegian Seventh-Day Adventists compared with the general population was not significantly different from unity (men 91, women 97). Persons converting late in life had a higher incidence than those converting at an earlier age. Respiratory cancers (standardized incidence ratio [SIR] 59, 95% CI = 36 to 91) and cancers with an unspecified site (SIR 53, 95% CI = 25 to 97) were rarer and cancer of the uterine corpus (SIR 164, 95% CI = 109 to 237) was more common in Seventh-Day Adventists before the age of 75 years. Inclusion of all registered Seventh-Day Adventists regardless of religious activity and the relatively low cancer incidence rates in the Norwegian population could contribute to the nonsignificant result with regard to total cancer. Main etiologic factors in cancer development in Norway should be sought in areas where Seventh-Day Adventists do not differ from the general population.

  19. Determinants of ischemic heart disease in Seventh-day Adventists: a review.

    Science.gov (United States)

    Fraser, G E

    1988-09-01

    Most data from several countries shows Seventh-day Adventist men to have lower rates of ischemic heart disease (IHD) mortality. Similar data for women are somewhat conflicting. There is clear evidence that Adventists have lower serum total cholesterol and lower serum HDL cholesterol with the ratio of total cholesterol to HDL cholesterol being similar to that of non-Adventists. The risk relationships of this ratio may differ in different populations. There is a certain amount of evidence that vegetarians may have lower blood pressures but this is not clearly supported by data from Seventh-day Adventists. The lower risk for IHD in Adventist men, at least, is probably related to their dietary habits, nonsmoking status, possibly their better exercise habits, and greater social support.

    1984-05-01

    The ISO-DALT system of two-dimensional electrophoresis was developed as a series of modifications of the original technique of O'Farrell. We have written a series of recipes and more detailed laboratory procedures that incorporate refinements and ''tricks of the trade'' as they have developed during our use of the system. The present collection is the seventh version in this series and represents the state of art as of May 1984. The seventh edition has been prepared to incorporate the changes that we have found helpful, as well as to add a few new sections such as silver staining, transfer gels, ACIDOs, and BASOs. Although these directions are specific for our laboratory, we hope that they will be helpful in other laboratories as well. Although some disagreement still exists, we recommend that gel patterns be oriented with acid isoelectric points (pIs) to the left and high sodium dodecyl sulfate (SDS) molecular weights at the top. This results in a system of pI and molecular weight values that run according to the Cartesian convention and facilitates the use of the charge and molecular weight standards described herein. 67 refs., 14 figs

  1. Urban flooding and Resilience: concepts and needs

    Science.gov (United States)

    Gourbesville, Ph.

    2012-04-01

    During the recent years, a growing interest for resilience has been expressed in the natural disaster mitigation area and especially in the flood related events. The European Union, under the Seventh Framework Programme (FP7), has initiated several research initiatives in order to explore this concept especially for the urban environments. Under urban resilience is underlined the ability of system potentially exposed to hazard to resist, respond, recover and reflect up to stage which is enough to preserve level of functioning and structure. Urban system can be resilient to lot of different hazards. Urban resilience is defined as the degree to which cities are able to tolerate some disturbance before reorganizing around a new set of structures and processes (Holling 1973, De Bruijn 2005). The United Nation's International strategy for Disaster Reductions has defined resilience as "the capacity of a system, community or society potentially exposed to hazards to adapt, by resisting or changing in order to reach and maintain an acceptable level of functioning and structure. This is determined by the degree to which the social system is capable of organizing itself to increase this capacity for learning from past disasters for better future protection and to improve risk reduction measures."(UN/ISDR 2004). According to that, system should be able to accept the hazard and be able to recover up to condition that provides acceptable operational level of city structure and population during and after hazard event. Main elements of urban system are built environment and population. Physical characteristic of built environment and social characteristic of population have to be examined in order to evaluate resilience. Therefore presenting methodology for assessing flood resilience in urban areas has to be one of the focal points for the exposed cities. Strategies under flood management planning related to resilience of urban systems are usually regarding controlling runoff

But it fact, most of the students in junior high school do not master vocabulary well. So, the teacher should be able to choose a good media to help students to increase their vocabulary. In this case, flash card with picture story is two of media that can be used to transfer vocabulary material for the students.   The objective of this research is to find the significant differences of using flash card with picture story in vocabulary, and to find which medium is more effective to use as media in vocabulary. This research was true experiment design. Pre test and post test were use to collect the data. There are two problems of the study, (1 are there any significant differences between flash card with picture story in vocabulary mastery for the seventh grade students in SMP PGRI 2 Margatiga academic years 2013/2014?, (2 which one is more effective media in vocabulary learning process, is it flash card or picture story at seventh grade of SMP PGRI 2 Margatiga, academic years 2013/2014?. As a source of data, the researcher utilized flash card with picture story to teach vocabulary for the students. The media help students to learn vocabulary easier and more interesting to understand the subject, so their vocabulary would increase.   The result of the research, it was found that the mean score of picture story in pre test is 53,86, in treatment is 81, and in post test 85,33. Meanwhile the mean score of the flash card media in pre test 59,33, in treatment is 73,5, and in post test is 80,66. It means that the student’s vocabulary has increased, and there is significant difference of using picture story and flash card in vocabulary instruction, and picture story was more effective to use in vocabulary instruction.

    Taylor, C B; Allen, E S; Mikkelson, B; Kang-Jey, H

    1976-10-01

    Serum cholesterol levels and dietary habits were surveyed in 27 male and 34 female Seventh-day Adventist. All subjects studied were lacto-ovo-vegetarians and a few consumed some meat products. Their serum cholesterol levels, significantly lower than those of the United States general population, showed no sex difference but increased with age and were higher in overweight males. Their levels, however, were much higher than those of true vegetarians which was most likely attributable to their consumption, even though to a limited acount, of dairy foods.

    1998-03-27

    To determine whether adult non-vegetarian Seventh-day Adventists differ in selected nutrition related health aspects from adult vegetarian Seventh-day Adventists. One hundred and forty-one Seventh-day Adventist church members responded to a general health questionnaire. Forty-seven sex and age matched subjects (23 non-vegetarians and 24 vegetarians) were selected for further investigation. Blood lipids, serum vitamin B12, folate, haemoglobin and ferritin levels were measured along with stature, weight and blood pressure. A quantitative 7-day diet record was also completed. Body mass index was similar between the non-vegetarian and vegetarian groups but diastolic blood pressure was higher for non-vegetarian than vegetarian males. Even though the dietary vitamin B12 intake was significantly lower (p Seventh-day Adventists appear likely to enjoy a lower risk of nutrition related chronic degenerative disease than the average New Zealander and have a satisfactory iron and vitamin B12 status.

    1984-01-01

    The life-style of adolescents attending a Seventh-Day Adventist boarding school was evaluated as it related to cardiovascular risk factors. The diet contained 34% calories as fat, with 11% derived from saturated fat. Total serum cholesterol levels were low (mean, standard deviation=138±15 mg per dl), and apolipoprotein B level was low as well (46±9 mg per dl). The high-density lipoprotein cholesterol level was within the usual range (52.4±13.3 mg per dl). Mean blood pressures were also low (systolic, 104.1±9.6 mm of mercury; diastolic, 65.7±9.7 mm of mercury). There was no self-reported use of cigarettes. If this life-style were to continue through adulthood, the incidence of premature atherosclerotic disease, particularly coronary artery disease, for this group might well be reduced, compared with other North Americans, as suggested by findings from previous studies of adult Seventh-Day Adventists.

    Full Text Available The physiological effects of natural and urban environments on the cardiovascular system of coronary artery disease (CAD patients are not fully understood. This controlled field study examines the effects of restorative walking in a park vs. in an urban street environment on CAD patients’ stress parameters and cardiac function. Methods: Twenty stable CAD patients were randomly allocated to 7 days controlled walking in a city park or in an urban street environment group. The relationship between different environmental exposures and health effects was analyzed using Wilcoxon signed-rank test and exact Mann-Whitney U test. Results: The mean reduction in cortisol levels and negative effects after the walk on the first day was greater in the city park than in the urban street exposed group, while a reduction in negative effects in the urban group were greater after seven days. The reduction in diastolic blood pressure (DBP in the park group was evident on the seventh day before the walk (−4 mm Hg, p = 0.031 and 60 min after the walk (−6.00 mm Hg, p = 0.002. The cortisol slope was negatively associated with the DBP changes (r = −0.514, p < 0.05. Conclusions: Physical activity in a green environment with noise and air pollution levels lower than in an urban environment has a greater positive effect on CAD patients’ stress level and hemodynamic parameters. Mitigating green environmental influences may allow urban residents to maintain health and reduce disability.

    1978-10-01

    Cell-free extracts were prepared from mixed fecal anaerobic bacteria grown from stools of 14 vegetarian Seventh-Day Adventists, 16 omnivorous control subjects, and eight patients recently diagnosed with cancer of the large bowel. Preparations were assayed for NAD- and NADP-dependent 3alpha-, 7alpha- and 12alpha-hydroxysteroid dehydrogenases with bile salts and androsterone as substrates (eight substrate-cofactor combinations were tested). A significant intergroup difference was observed in the amounts of NAD- and NADP-dependent 7alpha-hydroxysteroid dehydrogenase produced: bowel cancer patients exceeded controls, and controls exceeded Seventh-Day Adventists. Other enzyme activity comparisons were not significant. The pH values of the stools were significantly higher in cancer patients compared to Seventh-Day Adventists; values were 7.03 +/- 0.60 and 6.46 +/- 0.58 respectively. The pH value for controls was 6.66 +/- 0.62. A plot of pH value versus NADP-dependent 7alpha-hydroxysteroid dehydrogenase tended to separate the cancer patients from the other groups. Comparative data suggest that much of the 3alpha-hydroxysteroid dehydrogenase active against bile salt is also active against androsterone.

    Full Text Available Abstract Introduction: Polymorphous low grade adenocarcinoma (PLGA is a rare salivary gland neoplasm with an indolent course. It occurs primarily in the minor salivary glands but can rarely occur in the major salivary glands. It usually occurs in the fifth to seventh decades of life with female preponderance.   Case Report: A 16-year-old male presented with recurrent painless swelling in the right preauricular region and with a history of surgical intervention at the same site in the past. His histopathology report was suggestive of pleomorphic adenoma. The swelling recurred after one year of excision and a superficial parotidectomy was performed. The detailed histopathological examination was suggestive of Polymorphous low grade adenocarcinoma. In view of close margins, the patient was given adjuvant radiotherapy. Thirty-three months post-surgery, he is alive and disease-free. We describe a rare case of PLGA of the parotid gland in a teenager with its clinical characteristics, histopathological features, and treatment.   Conclusion: The occurrence of PLGA in the parotid gland is rare with only a few cases reported in literature. The diagnosis of PLGA is challenging due to morphological diversity.

  6. Religious Social Support and Hypertension Among Older North American Seventh-Day Adventists.

    Charlemagne-Badal, Sherma J; Lee, Jerry W

    2016-04-01

    Seventh-day Adventists have been noted for their unique lifestyle, religious practices and longevity. However, we know little about how religion is directly related to health in this group. Specifically, we know nothing about how religious social support is related to hypertension. Using data from the Biopsychosocial Religion and Health Study, we carried out a cross-sectional study of 9581 and a prospective study of 5720 North American Seventh-day Adventists examining new 534 cases of hypertension occurring up to 4 years later. We used binary logistic regression analyses to examine study hypotheses. Of the religious social support variables, in both the cross-sectional and prospective study only anticipated support significantly predicted hypertension, but the relationship was mediated by BMI. There were no significant race or gender differences. The favorable relationships between anticipated support and hypertension appear to be mediated by BMI and are an indication of how this dimension of religion combined with lifestyle promotes good health, specifically, reduced risk of hypertension.

  7. The Comparison and Modeling of the Driving Factors of Urban Expansion for Thirty-Five Big Cities in the Three Regions in China

    Directory of Open Access Journals (Sweden)

    Tian Guangjin

    2016-01-01

    Full Text Available This paper presents a national- and regional-scale urban growth model (NRUGM of China based on panel data analysis. Through the panel analysis, population growth, road construction, salary increment per capita, and secondary industry product increment were proven to be the major driving factors for national-scale urban expansion. According to Seventh Five-Year Plan, China had been divided into three regions, Eastern China, Middle China, and Western China, by their geographic position and economic development. We studied the relationship between urban expansion and the driving factors for the three regions between 1990 and 2010 in China. The driving factors of urban expansion were different for the different regions and periods. Population growth and road construction were identified as the two major factors driving urban expansion for Eastern China. Secondary industry and economic development had become the major driving factors for urban expansion over the last twenty years in Middle China. Over the same period, for Western China, economic growth had become the major driving factor for urban expansion. Our results have significant policy implications for China. The macrocontrol of the central government should utilize different policies to adjust urban expansion in the different regions.

    2005-02-01

    To examine the relationship between exposure to different forms of alcohol advertising and subsequent drinking among US adolescents and assess whether exposure to an alcohol and drug prevention program mitigates any such relationship. Regression models with multiple control variables examined the relationship between exposure to alcohol advertising in grade 8 and grade 9 drinking for two groups of South Dakotan adolescents: (1) seventh-grade non-drinkers (n = 1206) and (2) seventh-grade drinkers (n = 1905). Interactions between the intervention program and the significant advertising predictors were tested. Forty-one middle schools in South Dakota, USA. A total of 3111 seventh-graders followed through grade 9. Advertising variables were constructed for four types of alcohol advertising-television, in-store displays, magazines and concession stands. Other predictors tested included measures tapping social influences, social bonds, problem behavior, alcohol beliefs, television exposure and demographics. For seventh-grade non-drinkers, exposure to in-store beer displays predicted drinking onset by grade 9; for seventh-grade drinkers, exposure to magazines with alcohol advertisements and to beer concession stands at sports or music events predicted frequency of grade 9 drinking. Although exposure to television beer advertising had a significant bivariate relationship with alcohol use for grade 7 non-drinkers, it was not a significant predictor of drinking for either group in multivariate analyses. Participation in the prevention program, ALERT Plus, reduced future drinking for both groups and counteracted the effect of in-store beer displays. Several forms of alcohol advertising predict adolescent drinking; which sources dominate depends on the child's prior experience with alcohol. Alcohol prevention programs and policies should help children counter alcohol advertising from multiple sources and limit exposure to these sources.

    1983-01-01

    The relationship between dietary nutrients and plasma estrone, estradiol-17 beta, estriol, dehydroepiandrosterone sulfate, and prolactin levels was investigated in 14 premenopausal Seventh-day Adventist vegetarian (SV) women and 9 premenopausal non-Seventh-day Adventist nonvegetarian (NV) women. The SV subjects consumed less fat, especially saturated fat, and used significantly less fried food than the NV subjects. Plasma levels of estrone and estradiol-17 beta in the SV subjects were significantly lower than in the NV subjects. SV estradiol-17 beta and estriol levels were positively correlated with linoleic acid and protein intake, while NV prolactin levels were significantly correlated with intakes of oleic and linoleic acids and total fat. The data suggest that specific dietary nutrients were related to the hormonal milieu of these SV and NV subjects.

    Full Text Available The purpose of this study was to assess student knowledge of numeric, visual and algebraic representations. A definite gap between arithmetic and algebra has been documented in the research. The researchers’ goal was to identify a link between the two. Using four “Guess My Number problems, seventh and tenth grade students were asked to write numeric, visual, and algebraic representations. Seventh-grade students had significantly higher scores than tenth-grade students on visual representation responses. There were no significant differences between the seventh and tenth grade students’ responses on the numeric and algebraic representation. The researchers believed that the semi-concrete and visual models, such as used in this study, may provide the link between numeric and algebraic concepts for many students.

  2. Women in Engineering Program Advocates Network (WEPAN): Evaluation of the seventh annual conference

    Energy Technology Data Exchange (ETDEWEB)

    Brainard, S.G.

    1996-08-01

    The primary goals of the 1996 WEPAN Conference were to: (1) Conduct technical and programmatic seminars for institutions desiring to initiate, replicate, or expand women in engineering programs; (2) Provide assistance in fundraising and grant writing; (3) Profile women in engineering programs of excellence; (4) Sponsor inspiring, knowledgeable and motivational keynote speakers; and, (5) Offer a series of workshops focused on topics such as: establishing partnerships with industry, current research findings, retention strategies, issues affecting special populations, and early intervention techniques. In an effort to provide greater access for women to engineering careers, women in engineering program directors at Purdue University, Stevens Institute of Technology and the University of Washington joined together in 1990 to establish WEPAN, a national network of individuals interested in the recruitment, admission, retention, and graduation of women engineering students. This is the seventh year of operation. Success of this effort has been reflected in numerous ways: increased membership in the organization; increased number of women in engineering programs; increased number of women graduating in engineering; and grants from the U.S. Department of Energy, the National Science Foundation, the Alfred P. Sloan Foundation, the AT&T Foundation, and many other corporations to carry out the goals of WEPAN. The Seventh Annual Women in Engineering Conference entitled, Capitalizing on Today`s Challenges, was held in Denver, Colorado on June 1-4, 1996 at the Hyatt Regency. The conference brought together representatives from academia, government, and industry and examined current issues and initiatives for women in technology, science, and education. Building on the successes of the previous conferences, the seventh conference offered a new variety of speakers and topics.

    BACKGROUND AND OBJECTIVES: Children who experience bullying, a type of peer victimization, show worse mental and physical health cross-sectionally. Few studies have assessed these relationships longitudinally. We examined longitudinal associations of bullying with mental and physical health from elementary to high school, comparing effects of different bullying histories. METHODS: We analyzed data from 4297 children surveyed at 3 time points (fifth, seventh, and tenth grades) in 3 cities. We used multivariable regressions to test longitudinal associations of bullying with mental and physical health by comparing youth who experienced bullying in both the past and present, experienced bullying in the present only, experienced bullying in the past only, or did not experience bullying. RESULTS: Bullying was associated with worse mental and physical health, greater depression symptoms, and lower self-worth over time. Health was significantly worse for children with both past and present bullying experiences, followed by children with present-only experiences, children with past-only experiences, and children with no experiences. For example, 44.6% of children bullied in both the past and present were at the lowest decile of psychosocial health, compared with 30.7% of those bullied in the present only (P = .005), 12.1% of those bullied in the past only (P bullied (P bullying are associated with substantially worse health. Clinicians who recognize bullying when it first starts could intervene to reverse the downward health trajectory experienced by youth who are repeated targets. PMID:24534401

    Full Text Available In Slovenia, the existing studies of relations between physical activity (PA, academic performance (AP and urbanization grade have used subjective self-reporting tools for assessing physical activity, which usually led to an underestimation of true PA. We have attempted to overcome this and have investigated the link between PA in rural and urban Slovenian schoolchildren by an objective assessment of PA, using a multi-sensor SenseWear PRO armband. The analysis showed that urban children in Slovenia are more physically active than rural children are and achieve better AP (mathematics grade. Additionally, children who are active between 60 and 120 minutes of MVPA/day have higher AP than their peers who are active less than 60 or more than 120 minutes, whereas the latter groups did not differ in academic performance.

    Inadequate physical activity (PA) contributes to the high prevalence of overweight and obesity among U.S. adolescent girls. Barriers preventing adolescent girls from meeting PA guidelines have not been thoroughly examined. The threefold purpose of this study was to (a) determine pubertal stage, racial/ethnic, and socioeconomic status (SES) differences in ratings of interference of barriers to PA; (b) examine relationships between perceived barriers and age, body mass index, recreational screen time, sedentary activity, and PA; and (c) identify girls' top-rated perceived barriers to PA. Girls (N = 509) from eight Midwestern U.S. schools participated. Demographic, pubertal stage, perceived barriers, and recreational screen time data were collected via surveys. Height and weight were measured. Accelerometers measured sedentary activity, moderate-to-vigorous PA (MVPA), and light plus MVPA. Girls of low SES reported greater interference of perceived barriers to PA than those who were not of low SES (1.16 vs. 0.97, p = .01). Girls in early/middle puberty had lower perceived barriers than those in late puberty (1.03 vs. 1.24, p barriers were negatively related to MVPA (r = -.10, p = .03) and light plus MVPA (r = -.11, p = .02). Girls' top five perceived barriers included lack of skills, hating to sweat, difficulty finding programs, being tired, and having pain. Innovative interventions, particularly focusing on skill development, are needed to assist girls in overcoming their perceived barriers to PA.

    The purpose of this paper is to report our findings from a qualitative study intended to develop our understandings of: what high-poverty urban children understand and believe about food and food systems; and how such children transform and use that knowledge in their everyday lives (i.e. how do they express their scientific literacies including content understandings, process understandings, habits of mind in these content areas). This qualitative study is part of a larger study focused on understanding and developing science and nutritional literacies among high-poverty urban fourth-grade through sixth-grade students and their teachers and caregivers.

    The transition to middle school often presents behavioral and academic challenges to youths. Boys of color (i.e., African American and Hispanic in this study) may be especially vulnerable. In this study, peer nominations of aggressive and academic behaviors as well as youths' perceptions of how these behaviors were related to popularity in peer networks were obtained from the spring semester of fifth grade through the spring semester of seventh grade, with the transition occurring as the students entered the sixth grade. The sample included 188 boys (71 Caucasian, 90 African American, and 27 Hispanic) from an urban school district in the northeastern United States. Trajectory analyses showed that African American boys scored lower in studentship and higher in rule-breaking and aggressive (both physical and social) behaviors prior to the transition, and such differences among ethnic groups were largely maintained during the transition. Hispanic boys displayed decreases in their studentship during the transition. African American boys' perception of how studentship affects popularity was more positive than other boys prior to the transition, but it decreased during the transition. African American boys also endorsed rule breaking and physical and social aggression more positively for popularity prior to the transition, whereas Caucasian and Hispanic boys' endorsement increased during the transition and eventually caught up with those of African American boys in seventh grade. A positive within-individual association was found between youths' popularity perception and their behavior for studentship, rule breaking, and physical aggression, which did not differ by ethnicity. © 2013 American Orthopsychiatric Association.

    The urban stormwater runoff discharged to urban river, especially to rainfall source river, cannot be ignored. In this study, the Futian River watershed in Shenzhen city in a typical southern city of China is taken as the research object. In order to guide the pollution control for urban river, the eighteen rainfall events were monitored, and the total pollution features of the urban runoff outlet for this urban river were analyzed and discussed by using the process of pollutographs, the identifying to first flush, event mean concentration (EMC), etc. Results show that the concentrations of COD, SS, TN, TP and BOD5 are ten times more than the grade V of the environmental quality standards for surface water during the runoff time; the pollution caused by heavy metals (Cr, Ge, Cu, Hg and As) in runoff at a typical rainfall event is serious; the average and range of pollutant concentration at this runoff outlet in study area are evidently higher than at Shapingba in Chongqing city of China and at Silerwood in Canada, but are lower than at Shilipu in Wuhan city of China. The first flushes of COD, SS, BOD5, especially COD and SS, are evident, but the TN and TP are not. The average EMC of COD, TN, TP and BOD5 are 224.14, 571.15, 5.223, 2.04, 143.5 mg/L, respectively. To some extent, the EMC of COD is about two times of the value of the near cities, Macao and Zhuhai. The EMC of TN and TP are obviously higher than Beijing, Guangzhou and Shanghai. To compared with foreign counties, the EMC of the study area in Shenzhen is obviously much higher than the cities of Korean, USA and Canada. So the total pollution caused by the urban surface runoff in study area is serious and necessary to be treated.

E-V beliefs were assessed in seventh grade along with achievement, and enrollment was measured in eighth grade. Differential associations of motivation, achievement, and enrollment were examined across Hispanic and non-Hispanic populations. Expectancy for success and task value uniquely predicted seventh-grade achievement and eighth-grade algebra enrollment after controlling for prior achievement and a full set of demographic controls, including low socioeconomic status and English fluency. The association of interest value and achievement differentiated across Hispanic and non-Hispanic youth, suggesting that the effect of interest value on mathematics achievement was weaker for Hispanic youth than for non-Hispanics after accounting for success expectations and prior achievement.

    Adams, Kenneth Mark

    The purpose of this research was to investigate the relationship between the learning style perceptual preferences of fourth grade urban students and the attainment of selected physical science concepts for three simple machines as taught using learning cycle methodology. The sample included all fourth grade children from one urban elementary school (N = 91). The research design followed a quasi-experimental format with a single group, equivalent teacher demonstration and student investigation materials, and identical learning cycle instructional treatment. All subjects completed the Understanding Simple Machines Test (USMT) prior to instructional treatment, and at the conclusion of treatment to measure student concept attainment related to the pendulum, the lever and fulcrum, and the inclined plane. USMT pre and post-test scores, California Achievement Test (CAT-5) percentile scores, and Learning Style Inventory (LSI) standard scores for four perceptual elements for each subject were held in a double blind until completion of the USMT post-test. The hypothesis tested in this study was: Learning style perceptual preferences of fourth grade students as measured by the Dunn, Dunn, and Price Learning Style Inventory (LSI) are significant predictors of success in the acquisition of physical science concepts taught through use of the learning cycle. Analysis of pre and post USMT scores, 18.18 and 30.20 respectively, yielded a significant mean gain of +12.02. A controlled stepwise regression was employed to identify significant predictors of success on the USMT post-test from among USMT pre-test, four CAT-5 percentile scores, and four LSI perceptual standard scores. The CAT -5 Total Math and Total Reading accounted for 64.06% of the variance in the USMT post-test score. The only perceptual element to act as a significant predictor was the Kinesthetic standard score, accounting for 1.72% of the variance. The study revealed that learning cycle instruction does not appear

    Williams, Tammy Kay

    The purpose of this investigation was to examine the effects of a year long intensive extracurricular middle school science experience on the self-esteem, career goal orientation, and attitude toward science of eighth grade female students using both quantitative and qualitative methods. Sixteen self-selected eighth grade female students participated in extracurricular science experiences such as camping, rock climbing, specimen collecting and hiking, as well as meeting and interacting with female science role models. Data was collected using pre- and posttest methods using the Children's Attitude Toward Science Survey, the Coopersmith Self-Esteem Inventory, and the Self-Directed Search (SDS) Career Explorer. End of year science course grades were examined for seventh and eighth grades and compared to first semester high school grades. Qualitative data was in the form of: (1) focus group interviews conducted prior to field experiences, at the end of all field experiences, and at the end of the first semester of high school, and (2) journal entries from throughout the project. Qualitative data was examined for changes in student perceptions of science as a discipline, self as scientist, women in science, and social comparison of self in science.

  19. The correlation between academic achievements, self-esteem and motivation of female seventh grade students: A mixed methods approach

    Science.gov (United States)

    Henman, Karen

    During the early grades, female students generally display enthusiasm for learning science. As these same students go though school, however, their level of motivation changes. Once female students reach high school, many lack the confidence to take chemistry and physics. Then, in college they lack the background necessary to major in chemistry, physics, and engineering. This study used quantitative data to investigate the correlation between female students' motivation, self-esteem, and standards-based state science achievement tests combined with a qualitative survey of student's perceptions of parents' attitudes toward science. The Children's Science Motivation Inventory (CAIMI) determined students' levels of motivation toward science. The Coopersmith Self-esteem Inventory (CSEI) ascertained female students' overall self-esteem. The ISTEP+ exam given in the 6th grade measured the students' academic achievement in science. Trained examiners who interviewed students comprised the qualitative component of the study. Each examiner elaborated on selected questions from the CSEI and CAIMI to determine the students' perceptions of parental attitudes toward science. A multiple regression was used to determine the correlation between self-esteem, motivation, and achievement in science. The correlation was strongest between motivation. Interviews revealed parents and teachers had the most influence on students' perception of science. In understanding the correlation between female students' motivation, achievement, and self-esteem, schools will gain further knowledge into how students relate to the academic field of science and can thus promote females' participation in more science courses in high school. This then will provide females the necessary background knowledge to pursue a greater number of science majors in college.

    All age, sex, and racial groups are affected by the obesity epidemic in the United States, although disparities exist among these groups. The Seventh-day Adventists are a religious group of people who are believed to live longer and healthier lives than do their non-Adventist counterparts because they do not smoke or drink alcohol and they eat a healthier diet. This study assessed the prevalence of overweight and obesity among Seventh-day Adventist college students attending 2 private universities in the southern United States. Most students' body mass index (65.8%) was within the normal weight category, 3.7% were underweight, 20.6% were overweight, and 9.9% were obese. Body mass index > or = 25 kg/m2 was more prevalent among men and African Americans. In all ethnic subgroups, the prevalence of overweight and obesity was lower than that among non-Adventist students reported in other studies.

    To find a more effective method for the assessment of sustainable urban transport development, the comprehensive assessment model of sustainable urban transport development was established based on the unascertained measure. On the basis of considering the factors influencing urban transport development, the comprehensive assessment indexes were selected, including urban economical development, transport demand, environment quality and energy consumption, and the assessment system of sustainable urban transport development was proposed. In view of different influencing factors of urban transport development, the index weight was calculated through the entropy weight coefficient method. Qualitative and quantitative analyses were conducted according to the actual condition. Then, the grade was obtained by using the credible degree recognition criterion from which the urban transport development level can be determined. Finally, a comprehensive assessment method for urban transport development was introduced. The application practice showed that the method can be used reasonably and effectively for the comprehensive assessment of urban transport development.

    An earlier randomized controlled trial found that two middle school sexual education programs-a risk avoidance (RA) program and a risk reduction (RR) program-delayed initiation of sexual intercourse (oral, vaginal, or anal sex) and reduced other sexual risk behaviors in ninth grade. We examined whether these effects extended into 10th grade. Fifteen middle schools were randomly assigned to RA, RR, or control conditions. Follow-up surveys were conducted with participating students in 10th grade (n = 1,187; 29.2% attrition). Participants were 60% female, 50% Hispanic, and 39% black; seventh grade mean age was 12.6 years. In 10th grade, compared with the control condition, both programs significantly delayed anal sex initiation in the total sample (RA: adjusted odds ratio [AOR], .64, 95% confidence interval [CI], .42-.99; RR: AOR, .65, 95% CI, .50-.84) and among Hispanics (RA: AOR, .53, 95% CI, .31-.91; RR: AOR, .82, 95% CI, .74-.93). Risk avoidance students were less likely to report unprotected vaginal sex, either by using a condom or by abstaining from sex (AOR: .61, 95% CI, .45-.85); RR students were less likely to report recent unprotected anal sex (AOR: .34, 95% CI, .20-.56). Both programs sustained positive impact on some psychosocial outcomes. Although both programs delayed anal sex initiation into 10th grade, effects on the delayed initiation of oral and vaginal sex were not sustained. Additional high school sexual education may help to further delay sexual initiation and reduce other sexual risk behaviors in later high school years.

    Seventh-day Adventist women experience lower mortality rates from breast cancer than other white females in the United States. To evaluate the role of diet in relation to breast cancer within this unique population (more than one-half of all Adventist women are lacto-ovo-vegetarians), a nested case-control study was conducted including 142 cases of fatal breast cancer and 852 matched controls among California Seventh-day Adventist women in 1960-1980. No significant relations between the consumption of animal products (meat, milk, cheese, and eggs) and breast cancer were evident. Odds ratios of 1.00, 1.22, and 1.03 were observed for meat consumption categories of none or occasional, 1-3 days/week, and 4+ days/week, respectively. However, among those women who experienced a relatively early age at natural menopause (less than or equal to 48 years), a suggestive though nonsignificant, positive association between meat consumption and risk was noted. These relations remained unchanged after simultaneously controlling for the effects of other covariates (menstrual characteristics and obesity) via conditional logistic regression analysis. Risk was not related to age at first exposure to the vegetarian lifestyle nor to duration of exposure to the vegetarian lifestyle.

    School violence is a public health issue with direct and collateral consequences that has academic and social impacts for youth. School violence is often considered a uniquely urban problem, yet more research is needed to understand how violence in rural and suburban schools may be similar or different from urban counterparts. Using school violence data from a state with urban, suburban, and rural counties, we explored the landscape of school violence in Pennsylvania (PA) through mapping, descriptive statistics, and factor analysis. Results show school violence is not solely an urban problem. Schools in all county types and across grade levels deal with violence to varying degrees, and the majority of schools across county types experience low levels of violence. Types of violence experienced by PA schools loaded onto three factors, suggesting that targeted interventions may be better suited to addressing school violence.

    Full Text Available Objectives: The objective of this in vitro study was to compare the microtensile dentin bond strength (μTBS of five seventh-generation dentin bonding agents (DBA with fifth-generation DBA before and after thermocycling. Materials and Methods: Ten extracted teeth were assigned to fifth generation control group (optibond solo and each of the five experimental groups namely, Group I (G-Bond ,Group II (S 3 Clearfil, Group III (One Coat 7.0, Group IV (Xeno V, and Group V (Optibond all in one. The crown portions of the teeth were horizontally sectioned below the central groove to expose the dentin. The adhesive resins from all groups were bonded to the teeth with their respective composites. Specimens of sizes 1 × 1 × 6 mm 3 were obtained. Fifty specimens that bonded to dentin from each group were selected. Twenty-five of the specimens were tested for debonding without thermocycling and the remaining were subjected to thermocycling followed by μTBS testing. The data were analyzed with one-way ANOVA and Dunnett′s-test for comparison with the reference group(Vth Generation. Results: There was no significant difference (P > 0.05 between the fifth- and seventh-generation adhesives before and after thermocycling. The results of our study showed significantly higher value (P < 0.05 of μTBS of seventh-generation Group II (Clearfil S 3 compared to the fifth-generation before and after thermocycling. Conclusion: The study demonstrated that the Clearfil S 3 bond had the highest μTBS values. In addition, of the five tested seventh-generation adhesive resins were comparable to the fifth-generation DBA.

    Full Text Available Early intervention through hearing screening can reduce the negative impact of hearing loss for children. Optimal outcomes are achieved when an appropriate screening protocol is selected, a pathway for follow up care is established, and when a hearing conservation component is included. This study aimed to describe the outcomes of a hearing screening service provided to grade one learners in urban areas at Durban. A cross-sectional design was employed. Learners (n=241 were conveniently sampled from six randomly selected schools. They were screened using otoscopy, tympanometry and pure tone audiometry. Fifty eight participants (24% obtained a refer result, with 33% referred for diagnostic assessments, 29% for middle ear pathology and 38% for cerumen management. Findings further revealed that only 33% of referrals were followed up indicating poor compliance. Association between test results and income levels (P=0.38 as well as distance to the nearest health care facility (P=0.22 did not influence test outcomes. School aged children do present with common ear problems. Appropriate protocol selection, ensuring compliance to recommendations and education on hearing conservation are essential components of any health initiative.

  19. Nursing ethics in the seventh-day adventist religious tradition.

    Science.gov (United States)

    Taylor, Elizabeth Johnston; Carr, Mark F

    2009-11-01

    Nurses' religious beliefs influence their motivations and perspectives, including their practice of ethics in nursing care. When the impact of these beliefs is not recognized, great potential for unethical nursing care exists. Thus, this article examines how the theology of one religious tradition, Seventh-day Adventism (SDA), could affect nurses. An overview of SDA history and beliefs is presented, which explains why 'medical missionary' work is central to SDAs. Theological foundations that would permeate an SDA nurse's view of the nursing metaparadigm concepts of person, health, environment (i.e. community), and nursing (i.e. service) are presented. The ethical principles guiding SDA nurses (i.e. principled, case-based, and care ethics) and the implications of these theological foundations for nurses are noted in a case study.

  2. The effect of homework choices on achievement and intrinsic motivation

    Science.gov (United States)

    Christensen, Emily Fast

    The purpose of this research was to test an intervention of choices in homework on the achievement and intrinsic motivation of seventh-grade science students at a middle school. The intervention was based on concepts from the cognitive evaluation theory of Edward L. Deci and Richard M. Ryan (1985). The subjects were sixteen heterogeneous classes of seventh-grade students, who were divided among four teachers. Two randomly chosen classes from each teacher received choices in their homework and the remaining two classes of each teacher received similar homework assignments without choices. Two hypotheses were developed for this study: (1) Seventh-grade science students given choices in their homework would show an increase in intrinsic motivation as measured on a motivation orientation measure, compared to students not given choices in their homework, and (2) Seventh-grade science students given choices in their homework would show an increase in achievement on an achievement measure, compared to students not given choices in their homework. Having choices in homework did not increase intrinsic motivation or achievement. However, students who did their homework did significantly better on the posttest, and students who were more intrinsically motivated did significantly better on the posttest. Just doing the homework was important for achievement, and intrinsic motivation was linked to achievement.

    Sánchez, Brisa N.; Sanchez-Vaznaugh, Emma V.; Uscilka, Ali; Baek, Jonggyu; Zhang, Lindy

    2012-01-01

    Epidemiologic studies have observed influences of the food environment near schools on children’s overweight status but have not systematically assessed the associations by race, sex, and grade. The authors examined whether the associations between franchised fast food restaurant or convenience store density near schools and overweight varied by these factors using data for 926,018 children (31.3% white, 55.1% Hispanic, 5.7% black, and 8% Asian) in fifth, seventh, or ninth grade, nested in 6,362 schools. Cross-sectional data were from the 2007 California physical fitness test (also known as “Fitnessgram”), InfoUSA, the California Department of Education, and the 2000 US Census. In adjusted models, the overweight prevalence ratio comparing children in schools with 1 or more versus 0 fast food restaurants was 1.02 (95% confidence interval (CI): 1.01, 1.03), with a higher prevalence ratio among girls compared with boys. The association varied by student’s race/ethnicity (P = 0.003): Among Hispanics, the prevalence ratio = 1.02 (95% CI: 1.01, 1.03); among blacks, the prevalence ratio = 1.03 (95% CI: 1.00, 1.06), but among Asians the prevalence ratio = 0.94 (95% CI: 0.91, 0.97). For each additional convenience store, the prevalence ratio was 1.01 (95% CI: 1.00, 1.01), with a higher prevalence ratio among fifth grade children. Nuanced understanding of the impact of food environments near schools by race/ethnicity, sex, and grade may help to elucidate the etiology of childhood overweight and related race/ethnic disparities.

    2011-01-01

    Background and objective: Embolization of grade III–V intracranial DAVFs using Onyx is feasible with promising results, indicating stability at the time of mid-term follow-up. This article is to evaluate the role of transarterial Onyx embolization in the treatment of grade I and II intracranial dural arteriovenous fistulas (DAVFs), including its limitations and risks. Methods: We retrospectively studied consecutive 26 patients (8 women and 18 men) treated for an grade I and II intracranial DAVF since 2006 in whom a transarterial approach was attempted with Onyx-18 embolization. There were 18 transverse-sigmoid sinus, 4 cavernous sinus, 2 superior sagittal sinus, 1 inferior petrosal sinus and 1 intradiploic fistulas. Five fistulas were Type I, 8 were Type IIa, and 13 were Type IIa + b, according to the Cognard classification. The mean clinical follow-up period was 15.6 months. Results: Anatomic cure was proven in 13 patients (50%) and clinical cure was obtained in 17 cases (65.4%). These 13 cures were achieved after a single procedure. All these 13 patients underwent a follow-up angiography, which has confirmed the complete cure. Partial occlusion was obtained in 13 patients. Complications were as follows: 2 cardiac Onyx migration, 2 reflexive bradyarrythmia, 1 transient visual hallucination, 2 transient fifth nerve palsies and 1 permanent seventh nerve palsy in inferior petrosal sinus DAVF. Conclusions: Based on this experience, grade I and II intracranial DAVFs may be treated with transarterial Onyx embolization to reduce the shunted blood flow and to facilitate subsequent transvenous embolization or surgery.

    This study examined whether daily or almost daily lower-intensity physical activity was associated with reduced obesity, among 4824 African American, Hispanic, and White youth assessed in fifth and seventh grades. Regular lower-intensity physical activity was associated with reduced obesity only among Hispanic and White males and only in seventh grade, and not among youth in fifth grade, females, or African American males or females. Findings from this study suggest that the reduced obesity risk generally attributed to physical activity may not be consistent across racial/ethnic and gender groups of early adolescents. © The Author(s) 2014.

    Schofield, Thomas J; Conger, Rand D; Robins, Richard W

    2015-12-01

    Because adolescents vary in their susceptibility to peer influence, the current study addresses potential reciprocal effects between associating with deviant peers and use of alcohol, tobacco and other drugs (ATOD), as well as the potential buffering role of parental monitoring on these reciprocal effects. 674 children of Mexican origin reported at fifth and seventh grade (10.4 years old at fifth grade) on the degree to which they associated with deviant peers, intended to use alcohol, tobacco or other drugs (ATOD) in the future, and had used controlled substances during the past year. Trained observers rated parental monitoring from video-recorded family interactions at the first assessment. Youth who intended to use ATODs during fifth grade experienced a relative increase in number of deviant peers by seventh grade, and youth with more deviant peers in fifth grade were more likely to use ATODs by seventh grade. Parental monitoring buffered (i.e., moderated) the reciprocal association between involvement with deviant peers and both intent to use ATODs and actual use of ATODs. Parental monitoring can disrupt the reciprocal associations between deviant peers and ATOD use during the transition from childhood to adolescence. Copyright © 2015 Elsevier Ireland Ltd.

    The aims of the study were to estimate the prevalence of diabetic retinopathy (DR) and enumerate history-based risk factors in the urban slums of Western India. The population-based study was conducted in seven wards of Mumbai urban slums, where we screened 6569 subjects of ≥ 40 years age, with a response rate of 98.4%, for type 2 diabetes mellitus (T2DM) based on American Diabetes Association criteria. All subjects with T2DM underwent dilated 30° seven-field stereo-fundus-photography for DR severity grading based on modified Airlie House classification. A multivariate logistic regression model was used to assess the correlation of DR with the history-based risk factors. The prevalence of DR in the general population of Mumbai urban slums was 1.41% (95% CI 0.59-2.23) and in the T2DM population it was 15.37% (95% CI 8.87-21.87). The positive associations with DR were the longer duration of DM (≥ 11 years: OR, 12.77; 95% CI 2.93-55.61) and male gender (OR, 2.05; 95% CI 1.08-3.89); increasing severity of retinopathy was also significantly associated with longer duration of DM (p Mumbai urban slums. Duration of DM and male gender were significantly associated with DR. The slums in Western India show the trends of urban lifestyle influences similar to the rest of urban India.

    To pilot a study of social networks informing contextual analyses of sexual harassment and peer violence (SH/PV). Seventh and 8th grade students (N = 113) in an urban middle school were surveyed via a Web-based instrument. Boys and girls reported SH/PV victimization and perpetration at comparable rates. The proportion of nominated friends who reported SH/ PV outcomes was greater in boys' than in girls' social networks. Structural descriptors of social networks were not significant predictors of SH/PV outcomes. Collection of sensitive relationship data via a school-based Web survey is feasible. Full-scale studies and greater flexibility regarding the number of friendship nominations are recommended for subsequent investigations of potential sex differences.

    A population-based sample of Seventh-Day Adventists was studied to determine the relationship between vegetarian status, body mass index (BMI), obesity, diabetes mellitus (DM), and hypertension, in order to gain a better understanding of factors influencing chronic diseases in Barbados. A systematic sampling from a random start technique was used to select participants for the study. A standard questionnaire was used to collect data on demographic and lifestyle characteristics, to record anthropometrics and blood pressure measurements, and to ascertain the hypertension and diabetes status of participants. The sample population consisted of 407 Barbadian Seventh-Day Adventists (SDAs), who ranged in age from 25 to 74 years. One hundred fifty-three (37.6%) participants were male, and 254 (62.4%) were female, and 43.5% were vegetarians. The prevalence rates of diabetes and hypertension were lower among long-term vegetarians, compared to non-vegetarians, and long-term vegetarians were, on average, leaner than non-vegetarians within the same cohort. A significant association was observed between a vegetarian diet and obesity (vegetarian by definition P=.04, self-reported vegetarian P=.009) in this population. Other components of the study population lifestyle should be further analyzed to determine the roles they may plan in lessening the prevalence rates of obesity, diabetes, and hypertension.

    Data from a sample of 462 Mexican-American adolescents (M = 10.4 years, SD = .55; 48.1% girls), mothers, and fathers were used to test an ethnic socialization model of ethnic identity and self-efficacy that also considered mainstream parenting styles (e.g., authoritative parenting). Findings supported the ethnic socialization model: parents' endorsement of Mexican-American values were associated with ethnic socialization at fifth grade and seventh grade; maternal ethnic socialization at fifth grade and paternal ethnic socialization at seventh grade were associated with adolescents' ethnic identity exploration at 10th grade and, in turn, self-efficacy at 12th grade. The findings support ethnic socialization conceptions of how self-views of ethnicity develop from childhood across adolescence in Mexican-American children. © 2017 The Authors.

    2013-05-01

    The gastric cancer AJCC/UICC staging system recently underwent significant revisions, but studies on Asian patients have reported a lack of adequate discrimination between various consecutive stages. We sought to validate the new system on a U.S. population database. California Cancer Registry data linked to the Office of Statewide Health Planning and Development discharge abstracts were used to identify patients with gastric adenocarcinoma (esophagogastric junction and gastric cardia tumors excluded) who underwent curative-intent surgical resection in California from 2002 to 2006. AJCC/UICC stage was recalculated based on the latest seventh edition. Overall survival probabilities were calculated using the Kaplan-Meier method. Of 1905 patients analyzed, 54 % were males with a median age of 70 years. Median number of pathologically examined lymph nodes was 12 (range, 1-90); 40 % of patients received adjuvant chemotherapy, and 31 % received adjuvant radiotherapy. The seventh edition AJCC/UICC system did not distinguish outcome adequately between stages IB and IIA (P = 0.40), or IIB and IIIA (P = 0.34). By merging stage II into 1 category and moving T2N1 to stage IB and T2N2, T1N3 to stage IIIA, we propose a new grouping system with improved discriminatory ability In this first study validating the new seventh edition AJCC/UICC staging system for gastric cancer on a U.S. population with a relatively limited number of lymph nodes examined, we found stages IB and IIA, as well as IIB and IIIA to perform similarly. We propose a revised stage grouping for the AJCC/UICC staging system that better discriminates between outcomes.

    Costal cartilage is an important reconstructive tissue for correcting nasal deformities. Warping of costal cartilage, a recognized complication, can lead to significant functional and aesthetic problems. The authors present a technique to prevent warping that involves transverse slicing of the sixth-seventh costal cartilaginous junction, that when sliced perpendicular to the long axis of the rib, provides multiple long, narrow, clinically useful grafts with balanced cross-sections. The aim was to measure differences in cartilage warp between this technique (TJS) and traditional carving techniques. Costal cartilage was obtained from human subjects and cut to clinically relevant dimensions using a custom cutting jig. The sixth-seventh costal cartilaginous junction was sliced transversely leaving the outer surface intact. The adjacent sixth rib cartilage was carved concentrically and eccentrically. The samples were incubated and standardized serial photography was performed over time up to 4 weeks. Warp was quantified by measuring nonlinearity of the grafts using least-squares regression and compared between carving techniques. TJS grafts (n = 10) resulted in significantly less warp than both eccentrically (n = 3) and concentrically carved grafts (n = 3) (P < 0.0001). Warp was significantly higher with eccentric carving compared with concentric carving (P < 0.0001). Warp increased significantly with time for both eccentric (P = 0002) and concentric (P = 0.0007) techniques while TJS warp did not (P = 0.56). The technique of transverse slicing costal cartilage from the sixth-seventh junction minimizes warp compared with traditional carving methods providing ample grafts of adequate length and versatility for reconstructive requirements.

    Full Text Available Aim: To assess the awareness and knowledge levels about glaucoma and its determinants in an urban population of Chennai in south India. Materials and Methods: Chennai glaucoma study (CGS was a population based prevalence study to estimate the prevalence of glaucoma in a rural and urban south Indian population. A total of 3850 subjects aged 40 years or above participated in the urban arm of CGS. A systematic random sample of 1926 (50.0% subjects completed a questionnaire that assesses their awareness and knowledge level of glaucoma. Respondents "having heard of glaucoma" even before they were contacted/recruited for the study were defined as "aware" and respondents having some understanding of the eye disease were defined as "knowledgeable". Results: Overall 13.5% were aware of glaucoma, the age-gender adjusted rate for awareness was 13.3% (95% CI: 11.57 to 15.03. Two clinicians graded knowledge on glaucoma, based on the subject′s knowledge of risk factors, definitions and treatment aspects of glaucoma. Overall 8.7% had some knowledge about glaucoma. Among those who had knowledge 0.5% had good knowledge about glaucoma, 4% had fair knowledge and 4.2% had poor knowledge. We observed a very good agreement between the clinicians in grading knowledge (k =0.92. Determinants of glaucoma awareness and knowledge were higher levels of education, females, age, religion and family history of glaucoma. Conclusion: Awareness and knowledge about glaucoma was very low among the urban population of Chennai. We have found that younger subjects and men were less aware of glaucoma. Subjects with lower levels of education were less aware and knew less about glaucoma than their counterparts. The study findings stress the need for health education for effective prevention of blindness due to glaucoma.

    2004-11-01

    Three scales assessing individuation (Objective Measure of Ego-Identity Status [OMEIS], Separation-Individuation Test of Adolescence [SITA], and Multigenerational Interconnectedness Scale [MIS]) were administered to 40 female and 38 male Bedouin Arab adolescents and to 39 female and 38 male urban Arab adolescents in Grade 12. It was hypothesized that Bedouin Arab adolescents and female adolescents would manifest less individuation than urban Arab adolescents and male adolescents, respectively. Results from the OMEIS revealed that the identity foreclosed mean of the Bedouin adolescents was higher than that of the urban adolescents. As for the SITA, significant differences were found between Bedouin and urban Arabs in terms of dependency denial, separation anxiety, teacher enmeshment, peer enmeshment, and rejection expectancy. Significant gender differences were found in regard to dependency denial, and a borderline difference was found for separation anxiety. Significant effects of ethnicity and gender were found on the financial interconnectedness subscale of the MIS. The results support the present hypotheses concerning ethnicity differences and indicate that urbanization seems to narrow the differences in individuation between male and female adolescents. 2004 APA

    2018-04-01

    Full Text Available Climate change and accelerated urbanization have posed severe challenges to urban development, resulting in a growing series of climate and environmental problems that have a significant impact on industrial production and urban life. In a developing country such as China, more than 57% of the population lives in urban areas. It is vital for these cities to adapt to climate-induced risks. A better understanding of how to improve adaptive capacity could enhance the ability to achieve a desirable state when the city experiences stress. This paper used an integrated approach for evaluating the urban adaptive capacity to climate change. It developed the evaluation index system of urban adaptive capacity (UAC based on the driver–pressure–state–impact–response model (DPSIR, and adopted grey relational analysis (GRA and the entropy method to analyze the level of UAC in Changsha, the capital city of Hunan Province, from 2006 to 2015. The results revealed that the UAC of Changsha showed a significant increase from 2006 to 2015. Among the five first-grade indicators, the response dimension had the greatest influence on the improvement of UAC. The study may provide suggestions for adaptive capacity building and sustainable development in other urban areas.

    Full Text Available Intensification of public transport in urban areas due to increased mobility at regional and national levels, discrepancies among urban areas with same population and lack of statistical data related to performance and quality of public transport services are the main determinants of this paper. A separation line must be drawn between quality of services and performance indicators of public transport system. Service quality is a multi subjective outcome of an array of intangible variables. Service quality can be approached from four directions: consumer, vehicle performance (including the human operator, specialized company in passenger transport, and the Government (local Councils. Availability, comfort and convenience are the two main indicators that must be evaluated by citizens as being with high grades for a good quality of urban transport services. The instrument used to gather data is the preference survey.

    The objective was to explore obese adolescents perceptions about obesity among students in the seventh to ninth grade of a public school in Tamaulipas, Mexico. This is a qualitative study. Participants were 24 adolescents with a body mass index equal to or greater than the 95th percentile. Semistructured interviews were conducted until data saturation was reached and the meaning was understood. The adolescents defined obesity according to standards of measurement. They identified the hereditary factor as the main obesity cause, tended to underestimate obesity and had low self-esteem. They reported problems to do physical exercise and get clothes in order to improve their image, and feel rejected by their peers in school. It was identified that these adolescents have psychological defense mechanisms against obesity and that some of them are making efforts to lose weight. Obesity entails social and psychological health implications for persons suffering from this problem. Interventions should be put in practice.

    1994-05-01

    Cancer incidence was monitored in a population of 34,000 Seventh-day Adventists in California. By religious belief, Adventists do not consume tobacco, alcohol, or pork and approximately one-half adhere to a lacto-ovovegetarian lifestyle. Only a small percentage are pure vegetarians. Comparisons of cancer-incidence rates in this population with an external reference population were completed by calculating standardized morbidity ratios (SMRs) for all cancer sites. Also, within the population, relative risks were calculated by using data obtained from a detailed lifestyle questionnaire that members of the study population completed. For all cancer sites combined in males, the SMR was lower in the Adventists (SMR = 0.73). The SMR was also lower in males for most individual cancer sites. However, prostate cancer risk was higher. For females, the all-cancer SMR was lower but not significantly so (SMR = 92). Most site-specific SMRs were lower, although not as much as the male SMRs. The SMR for endometrial cancer was significantly higher in female Adventists.

    Asthma accounts for 12.8 million missed school days for children nationwide. Whether this excess absenteeism contributes to poor outcomes such as grade retention is of interest. The Clark County School District in Las Vegas, NV has incorporated the Federal "No Child Left Behind Act," which states that absences per individual in excess of 10 per school year are considered unapproved and may put a child at risk for repeating a grade. The purpose of this study was to determine if children with asthma are at increased risk for absenteeism associated with grade retention. Secondary data were obtained for students in attendance for the 2006-2007 school year. Days absent were weighted for enrollment time. Frequencies were obtained using descriptive statistics, and multivariate logistic regression was used to model the odds of absenteeism > 10 days per year. Of 300 881 students, 27 299 (9.1%) reported having asthma, as determined by school health records. The population was 52% male, 37% white, and 39% Hispanic. Significant predictors of missing > 10 days per school year included ethnicity, gender, grade, and health status (P 10 school days per year compared with healthy students or those with a medical condition other than asthma (P grade point average by race, gender, and asthma status. Children with asthma have a greater risk of absenteeism associated with grade retention. Therefore, improved asthma management and tailored education is necessary to identify and eliminate asthma triggers in the home and school setting for school-aged children.

    Full Text Available The objectives of this study were (a to report grade level prevalence in physical activity and sedentary behaviors and (b to examine academic burden associations with these behaviors. School-aged children (n = 48,118 reported their physical activity, perception of physical activity sufficiency, factors for activity insufficiency, homework hours, and screen time in a typical week. Data were analyzed using general linear models and logistic regression models of Complex Samples. Prevalence results showed that children had lower physical activity and lower screen viewing time, but higher homework time during transition grades (6th, 9th, and 12th and high school years. Academic burden was cited as the primary reason for not having sufficient physical activity (76.6%. Compared to those citing academic burden, students who did not report academic burden were significantly more likely to meet physical activity guidelines (Odds Ratio (OR = 5.38, 95% CI = 4.74–6.11, but less likely to meet screen time guidelines (OR = 0.78, 95% CI = 0.72–0.84, controlling for body mass index, gender, and grade level. Additionally, children who reported academic burdens had significantly longer average daily homework time than those who did not (p<0.01. Policy makers should promote physical activity and help children find a balance between homework and physical activity time particularly among the educational transition grades.

    1991-01-01

    Cancer incidence and mortality in a cohort of 6,000 Seventh-day Adventist nonsmokers who were residents of California were monitored for a 6-y period, and relationships with long-term ambient concentrations of total suspended particulates (TSPs) and ozone (O3) were studied. Ambient concentrations were expressed as mean concentrations and exceedance frequencies, which are the number of hours during which concentrations exceeded specified cutoffs (e.g., federal and California air quality standards). Risk of malignant neoplasms in females increased concurrently with exceedance frequencies for all TSP cutoffs, except the lowest, and these increased risks were highly statistically significant. An increased risk of respiratory cancers was associated with only one cutoff of O3, and this result was of borderline significance. These results are presented in the context of setting standards for these two air pollutants.

    Full Text Available Background. This ecological study examines the relationship between food desert prevalence and academic achievement at the school district level. Design and methods. Sample included 232 suburban and urban school districts in New York State. Multiple open-source databases were merged to obtain: 4th grade science, English and math scores, school district demographic composition (NYS Report Card, regional socioeconomic indicators (American Community Survey, school district quality (US Common Core of Data, and food desert data (USDA Food Desert Atlas. Multiple regression models assessed the percentage of variation in achievement scores explained by food desert variables, after controlling for additional predictors.Results. The proportion of individuals living in food deserts significantly explained 4th grade achievement scores, after accounting for additional predictors. School districts with higher proportions of individuals living in food desert regions demonstrated lower 4th grade achievement across science, English and math. Conclusions. Food deserts appear to be related to academic achievement at the school district level among urban and suburban regions. Further research is needed to better understand how food access is associated with academic achievement at the individual level.

    Full Text Available Rural–urban disparity in economic and social development in Ghana has led to disparities in educational resources and variations in students’ achievement in different parts of the country. Nonetheless, senior high schools (SHSs in rural and urban schools follow the same curriculum, and their students write the same West Africa Senior Secondary Certificate Examination (WASSCE, which qualifies them to access higher education in Ghana’s public universities. Urban SHSs are also recognized nationwide as good schools where students make it to university. Moreover, performance patterns with regard to admission of SHS graduates into university also vary between rural and urban schools; consequently, some parents do everything to get their children in urban SHSs, even consenting to placement in visual arts, a program deemed appropriate only for academically weak students. This study therefore adopted the qualitative-quantitative research approach with interview, observation, and questionnaire administration to investigate the critical factors that affect academic performance of SHS students, particularly those in visual arts as case study. Findings from six public SHSs in Kumasi—two each in rural, peri-urban, and urban areas—revealed that urban schools perform better than rural and peri-urban schools because they attract and admit junior high school graduates with excellent Basic Education Certificate Examination (BECE grades, have better infrastructure, more qualified teachers, prestigious names, and character that motivate their students to do well. This suggests that bridging the rural–urban gap in educational resources could promote quality teaching and learning, and thereby raise academic achievement for SHS students in Ghana.

    Otaala, Justine

    This study examined rural and urban Ugandan primary children's alternative ideas about animals through the use of qualitative research methods. Thirty-six children were selected from lower, middle, and upper primary grades in two primary schools (rural and urban). Data were collected using interview-about-instance technique. Children were shown 18 color photographs of instances and non-instances of familiar animals and asked to say if the photographed objects were animals or not. They were then asked to give reasons to justify their answers. The interviews were audiotaped and transcribed. The results indicate that children tended to apply the label "animal" to large mammals, usually found at home, on the farm, in the zoo, and in the wild. Humans were not categorized as animals, particularly by children in the lower grades. Although the children in upper grades correctly identified humans as animals, they used reasons that were irrelevant to animal attributes and improperly derived from the biological concept of evolution. Many attributes children used to categorize instances of animals were scientifically unacceptable and included superficial features, such as body outline, anatomical features (body parts), external features (visual cues), presence or absence and number of appendages. Movement and eating (nutrition) were the most popular attributes children used to identify instances of animals. The main differences in children's ideas emanated from the reasons used to identify animals. Older rural children drew upon their cultural and traditional practices more often than urban children. Anthropomorphic thinking was predominant among younger children in both settings, but diminished with progression in children's grade levels. Some of the implications of this study are: (1) teachers, teacher educators and curriculum developers should consider learners' ideas in planning and developing teaching materials and interventions. (2) Teachers should relate humans to other

    1990-08-01

    Mortality information was gathered for 110 Black Seventh-day Adventist members of seven churches in Metropolitan Atlanta, Georgia during the period 1980-87. Seventy-seven percent of the deaths were due to cardiovascular diseases; 8 percent due to cancer, the second leading cause of death. The cancer rate is extremely low in comparison to the proportion of deaths due to cardiovascular diseases. Subsequent research on this population will take into consideration lifestyle factors which could contribute to this finding.

    Holt, Melissa K; Finkelhor, David; Kantor, Glenda Kaufman

    2007-05-01

    This study explored the victimization experiences of urban elementary school students to determine whether subsets of youth emerged with similar victimization profiles (e.g., no victimization, multiple types of victimization). It also evaluated whether multiple victimization was associated with greater psychological distress and lower academic performance. Participants were 689 fifth grade students from an urban, ethnically diverse school district in the Northeast. Youth completed self-report measures in school about bullying victimization, victimization in the home and community, and psychosocial functioning. Cluster analysis suggested the existence of three distinct youth profiles: those with minimal victimization, those victimized primarily by their peers, and those with multiple types of victimizations. As hypothesized, youth with multiple victimizations experienced more psychological distress and earned lower grades than their peers. Findings highlight the heterogeneity of youth victimization experiences and their relations to functioning, and have implications for treatment planning among practitioners working with youth.

  3. Diet as primordial prevention in Seventh-Day Adventists.

    Science.gov (United States)

    Fraser, G E

    1999-12-01

    Epidemiologic studies of Seventh-Day Adventists have clearly shown that dietary habits are associated with risk of coronary heart disease (CHD) and other chronic diseases. However, a few surprising results emerge. Meat consumption is clearly hazardous for Adventist men by raising CHD mortality. However, no such effect was seen in women. Possible reasons are discussed. Our data, and that of others, strongly support the role of a fatty food, specifically nuts, as protective for CHD. The possible implications of this result for fat intake as a risk factor for CHD are discussed. In particular, it may be that consumption of modest quantities of certain fats is beneficial, rather than hazardous. The lower risk of CHD in Adventists probably has a complicated explanation and certainly cannot be entirely explained by their nonsmoking status or a superior serum lipid profile. Adventists are unique in that the majority of this group have adopted a dietary habit that is either vegetarian or tending in this direction. The power of incorporating health into a system of religious belief is discussed. Possibly others can also implement such a model to their advantage.

    Based on the theory of landscape ecological security pattern and the RS and GIS techniques, this paper analyzed the distribution of ecological security grades in Nanchong City, taking six elements including terrain condition, flood hazard, soil erosion, vegetation cover, geological disaster, and biological protection as the ecological constraints (or determinants) of urban expansion. According to the minimum cumulative resistance model, the ecological corridors and ecological nodes were built to strengthen the space contact of ecological network, and, on the basis of the protection of ecological safety, the reasonable trend of urban expansion and the optimization of space layout were investigated. The results showed that the ecological security of Nanchong City was quite good, with the regions of low ecological security mainly distributed in the west suburban mountains and the downstream region of Jialing River in the south of the City. Ecological elements were the most important constraints for the future expansion of urban space. There were more spaces for the urban expansion in the southern and northern parts of Nanchong City. To develop satellite towns would be the best selection to guarantee the ecological security of the city.

    2004-03-01

    To explore potential psychosocial predictors for initiation of sexual intercourse among middle-school, inner-city youth, using longitudinal data from the Healthy and Alive! project. We conducted hierarchical, logistic regression with adjustment for intraclass correlation over two sequential periods, including seventh and eighth grades (N = 3163), to assess the independent influence of psychosocial and demographic factors. Internally reliable scales to assess psychosocial influences were created, based on major theories of behavior. The sample was 52% female, 51% black, 30% Hispanic, 9% white, and 3% Asian. At baseline, 13% of girls and 39% of boys reported already having initiated sexual intercourse. Personal and perceived peer norms about refraining from sex were a strong and consistent protective factor. Alcohol and other drug use, poor academic performance, male gender, and black race were consistent risk factors. Self-efficacy showed a mixed effect: protective in the seventh grade but increasing risk in the eighth grade. Speaking a language other than English was a protective factor in seventh grade. Both psychosocial and demographic factors provided independent explanatory power. Psychosocial factors, particularly norms about having sex, influence initiation of sexual intercourse. These data suggest that programs to delay initiation of sexual intercourse should reinforce norms about refraining from sex.

    To investigate changes in and the impact of grading scales from 2005 to 2010 and explore pharmacy faculty and student perceptions of whole-letter and plus/minus grading scales on cumulative grade point averages (GPAs) in required courses. Grading scales used in 2010 at the University of Cincinnati College of Pharmacy were retrospectively identified and compared to those used in 2005. Mean GPA was calculated using a whole-letter grading scale and a plus/minus grading scale to determine the impact of scales on GPA. Faculty members and students were surveyed regarding their perceptions of plus/minus grading. Nine unique grading scales were used throughout the curriculum, including plus/minus (64%) and whole-letter (21%) grading scales. From 2005 to 2010 there was transition from use of predominantly whole-letter scales to plus/minus grading scales. The type of grading scale used did not affect the mean cumulative GPA. Students preferred use of a plus-only grading scale while faculty members preferred use of a plus/minus grading scale. The transition from whole-letter grading to plus/minus grading in courses from 2005 to 2010 reflects pharmacy faculty members' perception that plus/minus grading allows for better differentiation between students' performances.

    2014-01-01

    To identify magnetic resonance imaging (MRI) features which differentiate low-grade chondral lesions (atypical cartilaginous tumours/grade 1 chondrosarcoma) from high-grade chondrosarcomas (grade 2, grade 3 and dedifferentiated chondrosarcoma) of the major long bones. We identified all patients treated for central atypical cartilaginous tumours and central chondrosarcoma of major long bones (humerus, femur, tibia) over a 13-year period. The MRI studies were assessed for the following features: bone marrow oedema, soft tissue oedema, bone expansion, cortical thickening, cortical destruction, active periostitis, soft tissue mass and tumour length. The MRI-features were compared with the histopathological tumour grading using univariate, multivariate logistic regression and receiver operating characteristic curve (ROC) analyses. One hundred and seventy-nine tumours were included in this retrospective study. There were 28 atypical cartilaginous tumours, 79 grade 1 chondrosarcomas, 36 grade 2 chondrosarcomas, 13 grade 3 chondrosarcomas and 23 dedifferentiated chondrosarcomas. Multivariate analysis demonstrated that bone expansion (P = 0.001), active periostitis (P = 0.001), soft tissue mass (P < 0.001) and tumour length (P < 0.001) were statistically significant differentiating factors between low-grade and high-grade chondral lesions with an area under the ROC curve of 0.956. On MRI, bone expansion, active periostitis, soft tissue mass and tumour length can reliably differentiate high-grade chondrosarcomas from low-grade chondral lesions of the major long bones. (orig.)

    1980-11-01

    In previous reports concerning cancer among Seventh-Day Adventists (SDA), comparisons were made only with the general population. This report compared California SDA to a sample of non-SDA who were demographically similar to SDA. The study consisted of 17 years of follow-up (1960--76) on 22,940 white California SDA and 13 years of follow-up (1960--72) on 112,725 white California non-SDA. Both groups completed the same base-line questionnaire in 1960. Deaths were ascertained by annual contacts with each study member and by computer-assisted record linkage with the California State death certificate file. Results indicated that, with the exception of colon-rectal cancer and smoking-related cancers, the difference in risk of fatal cancer between SDA and non-SDA was substantially reduced when SDA were compared with a more socioeconomically similar population. The persistence of the low risk for colon-rectal cancer can probably be attributed to some aspect of the diet or life-style of the SDA.

    2009-07-01

    Inflammatory conditions in selected organs increase the risk of cancer. An inflammatory component is present also in the microenvironment of tumors that are not epidemiologically related to inflammation. Recent studies have begun to unravel molecular pathways linking inflammation and cancer. In the tumor microenvironment, smoldering inflammation contributes to proliferation and survival of malignant cells, angiogenesis, metastasis, subversion of adaptive immunity, reduced response to hormones and chemotherapeutic agents. Recent data suggest that an additional mechanism involved in cancer-related inflammation (CRI) is induction of genetic instability by inflammatory mediators, leading to accumulation of random genetic alterations in cancer cells. In a seminal contribution, Hanahan and Weinberg [(2000) Cell, 100, 57-70] identified the six hallmarks of cancer. We surmise that CRI represents the seventh hallmark.

    1991-03-01

    The low risk of cancer in Seventh-Day Adventists (SDAs) has been suggested to be due to genetic selection. To investigate this claim we examined the sister chromatid exchange (SCE) frequency in peripheral blood lymphocytes in 16 SDA children in Tromsø, all aged 0.5-8 years and 16 controls matched for sex and age. In 12 of 16 pairs, the SDA children had a lower SCE frequency than the controls. The mean difference was 4.06 (95% confidence interval -17.02-8.89, P = 0.51). There was no sex difference, and no correlation between age and SCE frequency. The genetic starting point with regard to SCE frequency seems to be the same for SDA children and controls.

    To investigate the status of puberty timing and relevant factors of early puberty timing in children from grade one to four in urban primary schools of Chongqing. According to the purposive sample method, four urban primary schools in Chongqing were selected and of which 1471 children from grade one to four who have obtained informed consent were recruited. Questionnaire survey on social-demographic characteristics and family environment (e.g., age, parents' relationship, diet and lifestyle, etc), and Pubertal Development Scale (PDS) survey and physical examination (measurements of height, weight, pubertal development status, etc) were conducted. P25, P50, P75 ages of each important pubertal event were calculated by probit regression. Univariate and multivariate analysis were used to analyze relevant factors. The detection rate of early puberty timing was 17.7%, and the median ages of the onset of breast and testicular development were 10.77 and 11.48 years old, respectively. Multivariate logistic regression showed that early puberty timing occurred more likely in girls than in boys (OR = 0.561, 95% CI 0.406-0.774), and bad relationship between parents (OR = 1.320, 95% CI 1.007-1.729) and hair-products-use (OR = 1.685, 95%, CI 1.028-2.762) were risk factors of early puberty timing. Early onset of puberty in urban Chongqing is still exist. Gender, parents' relationship, and hair-products-use have an essential impact on early puberty timing.

    The Fuhrman nuclear grade is the reference histoprognostic grading system routinely used all over the world for renal cell carcinoma. Studies measuring the inter-observer and intra-observer concordance of Fuhrman grade show poor results in terms of reproducibility and repeatability. These variations are due to a certain degree of subjectivity of the pathologist in application of the definition of tumour grade, particularly nuclear grade. Elements able to account for this subjectivity in renal cell carcinoma are identified from a review of the literature. To improve the reliability of nuclear grade, the territory occupied by the highest grade must be specified and the grades should probably be combined. At the present time, regrouping of grade 1 and 2 tumours as low grade and grade 3 and 4 tumours as high grade would achieve better reproducibility, while preserving the prognostic: value for overall survival. The development of new treatment modalities and their use in adjuvant situations will imply the use of reliable histoprognostic factors to specify, indications.

    Full Text Available Along with urbanization, sealing of vegetated land and evaporation surfaces by impermeable materials, lead to changes in urban climate. This phenomenon is observed as temperatures several degrees higher in densely urbanized areas compared to the rural land at the urban fringe particularly at nights, so-called Urban Heat Island. Urban Heat Island (UHI effect is related with urban form, pattern and building materials so far as it is associated with meteorological conditions, air pollution, excess heat from cooling. UHI effect has negative influences on human health, as well as other environmental problems such as higher energy demand, air pollution, and water shortage. Urban Heat Island (UHI effect has long been studied by observations of air temperature from thermometers. However, with the advent and proliferation of remote sensing technology, synoptic coverage and better representations of spatial variation of surface temperature became possible. This has opened new avenues for the observation capabilities and research of UHIs. In this study, "UHI effect and its relation to factors that cause it" is explored for İzmit city which has been subject to excess urbanization and industrialization during the past decades. Spatial distribution and variation of UHI effect in İzmit is analysed using Landsat 8 and ASTER day & night images of 2015 summer. Surface temperature data derived from thermal bands of the images were analysed for UHI effect. Higher temperatures were classified into 4 grades of UHIs and mapped both for day and night. Inadequate urban form, pattern, density, high buildings and paved surfaces at the expanse of soil ground and vegetation cover are the main factors that cause microclimates giving rise to spatial variations in temperatures across cities. These factors quantified as land surface/cover parameters for the study include vegetation index (NDVI, imperviousness (NDISI, albedo, solar insolation, Sky View Factor (SVF, building

    Along with urbanization, sealing of vegetated land and evaporation surfaces by impermeable materials, lead to changes in urban climate. This phenomenon is observed as temperatures several degrees higher in densely urbanized areas compared to the rural land at the urban fringe particularly at nights, so-called Urban Heat Island. Urban Heat Island (UHI) effect is related with urban form, pattern and building materials so far as it is associated with meteorological conditions, air pollution, excess heat from cooling. UHI effect has negative influences on human health, as well as other environmental problems such as higher energy demand, air pollution, and water shortage. Urban Heat Island (UHI) effect has long been studied by observations of air temperature from thermometers.

    Urbanization put immense pressure on urban infrastructure and services. Burdened with unrelenting pressure, the founded areas of Lahore have now been converted into slums. Poor services, urban infrastructure and dilapidated building have made lives of the resident miserable. A significant proportion of the people is living in dangerous buildings which could be declared unfit for habitation under section 34 of Punjab Local Government Ordinance 2001 (PLGO 2001). The paper attempts to highlight situations of two founded areas of Lahore namely, Icchra and Sanda in comparison with slums areas to grade living standards of the people. Actions under PLGO 2001 and urban renewal programs are suggested to revitalize such areas. (author)

  17. California's population geography: lessons for a fourth grade class.

    Science.gov (United States)

    Rushdoony, H A

    1978-11-01

    Purpose of this paper is to present a model for teaching fourth grade children some aspects of the population geography of California from a nontextual approach. The objective is to interest and instruct children in the mobility of the people, and on the reasons why so many families have moved to California from other states. Students should be alerted not only to internal migration problems, but to the excess of births over deaths. Materials necessary for the lessons are transparencies, overhead projector, marking pencils, chalk and chalkboard. After showing the students that California population has approximately doubled every 20 years, the students should be encouraged to find reasons explaining why people have moved to the state, should be able to categorize those reasons under the terms industrial/manufacturing, agricultural, urban or recreational, should learn how to plot population distribution on a California regional outline map, and should attempt to explain why certain parts of California are more popular than others. The teaching model described in this paper may be replicated with modfications for any grade level and area of study.

    1992-02-01

    In this study, 549 youths in the fourth grade, seventh grade, tenth grade, and college completed Network of Relationship Inventories assessing their perceptions of their relationships with significant others. The findings were largely consistent with 7 propositions derived from major theories of the developmental courses of personal relationships. In particular, mothers and fathers were seen as the most frequent providers of support in the fourth grade. Same-sex friends were perceived to be as supportive as parents in the seventh grade, and were the most frequent providers of support in the tenth grade. Romantic partners moved up in rank with age until college, where they, along with friends and mothers, received the highest ratings for support. Age differences were also observed in perceptions of relationships with grandparents, teachers, and siblings. Finally, age differences in perceived conflict, punishment, and relative power suggested that there was a peak in tension in parent-child relationships in early and middle adolescence. Discussion centers around the role various relationships are perceived as playing at different points in development.

    more strongly related to local geologic setting, slope, watershed topography, and river-engineering practices than to urbanization. Historical local river-engineering features such as channelization, bank stabilization, and grade controls may have confounded relations among habitat characteristics and urbanization. A number of hydrologic-condition metrics (including flashiness and duration of high flow during pre- or post-ice periods) showed strong relations to the urban intensity index. Hydrologic-condition metrics cannot be used alone to predict habitat or geomorphic change. Chloride and SPMD measures of potential toxicity and polycyclic aromatic hydrocarbon concentrations showed the strongest positive correlations to urbanization including increases in road infrastructure, percentage of impervious surface in the watershed, urban land cover, and land-distribution related to urban land cover. This suggests that automobiles and the infrastructure required to support automobiles are a significant source of these compounds in this study area. Chloride in spring and summer showed a significant positive correlation with the urban intensity index; concentrations increased with increasing road infrastructure, urban land cover, and a number of landscape variables related to urbanization. Spring concentrations of sulfate, prometon, and diazinon correlated to fewer urban characteristics than chloride, including increases in road infrastructure, percentage of impervious surface, and urban land cover. Changes in biological communities correlated to the urban intensity index or individual urban-associated variables. Decreased percentages of pollution-sensitive diatoms and diatoms requiring high dissolved-oxygen saturation correlated to increases in the percentage of developed urban land, total impervious surface, stream flashiness, population density, road-area density, and decreases in the percentage of wetland in the watershed.

    2000-02-01

    This study investigated differences in demographic data, self-esteem, and coping skills for 225 students in Grade 7 who reported having a partner with whom they wanted to have a baby and 946 students who did not. Data were collected on the Rosenberg Self-esteem Scale, the Family Crisis-oriented Personal Evaluation Scale, and questions related to attitudes towards teen pregnancy and demographic data. The sample included 548 (46.8%) boys and 624 (53.2%) girls whose mean age was 13.2 yr. Students with a partner had significantly lower scores on the curriculum questions, self-esteem, and family coping skills, combined with higher scores in passivity. They indicated a desire to have a greater number of children, beginning by having their first child at a younger age and believed that having a baby improves a couple's relationship. Possible approaches may include effective teaching methods to overcome passivity through boosting self-confidence, goal-setting, and acquiring a purpose in life besides parenting a child.

    Östberg, Johan; Delshammar, Tim; Wiström, Björn; Nielsen, Anders Busse

    2013-03-01

    Tree inventories are expensive to conduct and update, so every inventory carried out must be maximized. However, increasing the number of constituent parameters increases the cost of performing and updating the inventory, illustrating the need for careful parameter selection. This article reports the results of a systematic expert rating of tree inventories aiming to quantify the relative importance of each parameter. Using the Delphi method, panels comprising city officials, arborists, and academics rated a total of 148 parameters. The total mean score, the top ranking parameters, which can serve as a guide for decision-making at practical level and for standardization of tree inventories, were: Scientific name of the tree species and genera, Vitality, Coordinates, Hazard class, and Identification number. The study also examined whether the different responsibilities and usage of urban tree databases among organizations and people engaged in urban tree inventories affected their prioritization. The results revealed noticeable dissimilarities in the ranking of parameters between the panels, underlining the need for collaboration between the research community and those commissioning, administrating, and conducting inventories. Only by applying such a transdisciplinary approach to parameter selection can urban tree inventories be strengthened and made more relevant.

    The web-based Food Behaviour Questionnaire (FBQ) includes a 24-hour diet recall, a food frequency questionnaire, and questions addressing knowledge, attitudes, intentions, and food-related behaviours. The survey has been revised since it was developed and initially validated. The current study was designed to obtain qualitative feedback and to validate the FBQ diet recall. "Think aloud" techniques were used in cognitive interviews with dietitian experts (n=11) and grade six students (n=21). Multi-ethnic students (n=201) in grades six to eight at urban southern Ontario schools completed the FBQ and, subsequently, one-on-one diet recall interviews with trained dietitians. Food group and nutrient intakes were compared. Users provided positive feedback on the FBQ. Suggestions included adding more foods, more photos for portion estimation, and online student feedback. Energy and nutrient intakes were positively correlated between FBQ and dietitian interviews, overall and by gender and grade (all p<0.001). Intraclass correlation coefficients were ≥0.5 for energy and macro-nutrients, although the web-based survey underestimated energy (10.5%) and carbohydrate (-15.6%) intakes (p<0.05). Under-estimation of rice and pasta portions on the web accounted for 50% of this discrepancy. The FBQ is valid, relative to 24-hour recall interviews, for dietary assessment in diverse populations of Ontario children in grades six to eight.

    Seventh-day syndrome (7DS) is an early serious complication of liver transplantation, characterized by sudden failure of a previously normally functioning liver graft ∼1 week after the surgery. Although it is an uncommon event, it has major associated mortality. As its etiology is yet to be recognized, the only currently available treatment is retransplantation. We present 3 cases of orthotopic liver transplantation recipients who had an initial uneventful recovery after surgery followed by a dramatic rise of serum liver enzyme levels ∼7 days later and hepatic failure with subsequent graft loss and death despite high-dose immunosuppressive therapy. Histologic findings showed massive centrolobular hemorrhage and hepatocellular necrosis with reduced inflammation. It is essential to review and accumulate more clinical and laboratory information to better understand this syndrome and to better prevent and treat it. Copyright © 2015 Elsevier Inc.

    The purpose of the study was to determine if barriers in rural areas might decrease an adolescent's likelihood of obtaining effective contraception. Previous studies have reported mixed results in comparisons of rural and urban contraception use. Electronic survey. Midwestern Public University. Undergraduate and graduate women. Questionnaire. Participants retrospectively recalled their contraceptive use and barriers to contraceptive use between the 9th and 12th grades. A Barriers to Contraception Use Scale was created using exploratory factor analysis and yielded 31 questions with 1 underlying factor: barriers. Participants were identified as rural or urban using the Office of Management and Budget (OMB) definition and the participant's self-identification. Overall, rural participants endorsed more barriers to accessing contraceptives than urban participants using the OMB definition (χ(2) (2; n = 388) = 2.04; P .05. The Barriers to Contraception Use Scale total score predicted whether an individual would have a prescription for contraceptives 70.5% of the time compared to the base rate of 54.1%. Although no rural-urban differences in actual contraception use were found, rural participants reported more barriers to accessing contraception, and those who endorsed more barriers were less likely to obtain contraceptives while in high school. Pregnancy prevention programs should thus take these barriers into account when developing future interventions. Copyright © 2016 North American Society for Pediatric and Adolescent Gynecology.

    The purpose of the study was to determine if students' cultural capital is a significant predictor of 8th grade science achievement test scores in urban locales. Cultural capital refers to the knowledge used and gained by the dominant class, which allows social and economic mobility. Cultural capital variables include magazines at home and parental education level. Other variables analyzed include socioeconomic status (SES), gender, and English language learners (ELL). This non-experimental study analyzed the results of the 2011 Eighth Grade Science National Assessment of Educational Progress (NAEP). The researcher analyzed the data using a multivariate stepwise regression analysis. The researcher concluded that the addition of cultural capital factors significantly increased the predictive power of the model where magazines in home, gender, student classified as ELL, parental education level, and SES were the independent variables and science achievement was the dependent variable. For alpha=0.05, the overall test for the model produced a R2 value of 0.232; therefore the model predicted 23.2% of variance in science achievement results. Other major findings include: higher measures of home resources predicted higher 2011 NAEP eighth grade science achievement; males were predicted to have higher 2011 NAEP 8 th grade science achievement; classified ELL students were predicted to score lower on the NAEP eight grade science achievement; higher parent education predicted higher NAEP eighth grade science achievement; lower measures of SES predicted lower 2011 NAEP eighth grade science achievement. This study contributed to the research in this field by identifying cultural capital factors that have been found to have statistical significance on predicting eighth grade science achievement results, which can lead to strategies to help improve science academic achievement among underserved populations.

  9. Effects of traditional teaching vs a multisensory instructional package on the science achievement and attitudes of English language learners middle-school students and English-speaking middle-school students

    This research was designed to determine the relative effectiveness of a Multi-sensory Instructional Package (MIP) (Dunn & Dunn, 1992) versus Traditional Teaching (TT) on the science achievement- and attitude-test scores of middle-school English Language Learner (ELL) and English-speaking sixth-, seventh-, and eighth-grade middle-school students. The dependent variables were students' science- and attitude-test scores. The independent variables were the two instructional strategies, ELL and English-speaking (Non-ELL) status, and three grade levels. The sample consisted of 282 sixth-, seventh-, and eighth-grade ELL and Non-ELL middle-school students. Learning Styles: The Clue to You! (LS: CY) (Burke & Dunn, 1998) was administered to determine learning-style preferences. The control groups were taught sixth-, seventh-, and eighth-grade science lessons traditionally and the experimental groups were instructed on the same units using MIPs. The Semantic Differential Scale (SDS) (Pizzo, 1981) was administered to reveal attitudinal differences. All three groups experienced both traditional and multi-sensory instruction in all three sub-units. The data subjected to statistical analyses supported the use of an MIP rather than a traditional approach for teaching science content to both ELLs and English-speaking middle-school students. Analysis of variance (ANOVA) revealed a positive and significant impact on achievement scores. Furthermore, the students indicated significantly more positive attitudes when instructed with an MIP approach.

    Full Text Available To assess the prevalence of cardiovascular disease risk among urban public school students through a collaborative school district and university partnership.Children and adolescents in grades K-12 from 24 urban public schools participated in measurements of height, weight, and other health metrics during the 2009-2010 school year. Body mass index (BMI percentiles and z-scores were computed for 4673 students. President's Challenge 1-mile endurance run was completed by 1075 students ages 9-19 years. Maximal oxygen consumption (⩒O2max was predicted using an age-, sex-, and BMI-specific formula to determine health-related fitness. Resting blood pressure (BP was assessed in 1467 students. Regression analyses were used to compare BMI z-scores, fitness, and age- and sex-specific BP percentiles across grade levels. Chi-square tests were used to explore the effect of sex and grade-level on health-related outcomes.Based on BMI, 19.8% were categorized as overweight and 24.4% were obese. Included in the obese category were 454 students (9.7% of sample classified with severe obesity. Using FITNESSGRAM criteria, 50.2% of students did not achieve the Healthy Fitness Zone (HFZ; the proportion of students in the Needs Improvement categories increased from elementary to middle school to high school. Male students demonstrated higher fitness than female students, with 61.4% of boys and only 35.4% of girls meeting HFZ standards. Elevated BP was observed among 24% of 1467 students assessed. Systolic and diastolic BP z-scores revealed low correlation with BMI z-scores.A community-university collaboration identified obesity, severe obesity, overweight, and low aerobic fitness to be common risk factors among urban public school students.

    1989-08-01

    Breast cancer incidence was monitored in a cohort of 20,341 California Seventh-day Adventist women who completed a detailed lifestyle questionnaire in 1976, and who were followed for 6 years. There were 215 histologically confirmed primary breast cancer detected among some 115,000 person-years of follow-up. Mean age at diagnosis was 66 years, indicating a primarily postmenopausal case series. Established risk factors for breast cancer showed strong relationships to risk in these data. Age at first live birth, maternal history of breast cancer, age at menopause, educational attainment, and obesity were all significantly related to risk. However, increasing consumption of high fat animal products was not associated with increased risk of breast cancer in a consistent fashion. Nor were childhood and early teenage dietary habits (vegetarian versus nonvegetarian) related to subsequent, adult risk of developing breast cancer. Also, a derived index of percent of calories from animal fat in the adult years was not significantly related to risk. These results persisted after simultaneously controlling for other, potentially confounding variables, utilizing Cox proportional hazard regression models.

    2013-06-01

    Grades are the fundamental currency of our educational system; they signal academic achievement and non-cognitive skills to parents, employers, postsecondary gatekeepers, and students themselves. Grade inflation compromises the signaling value of grades, undermining their capacity to achieve the functions for which they are intended. We challenge the 'increases in grade point average' definition of grade inflation and argue that grade inflation must be understood in terms of the signaling power of grades. Analyzing data from four nationally representative samples, we find that in the decades following 1972: (a) grades have risen at high schools and dropped at four-year colleges, in general, and selective four-year institutions, in particular; and (b) the signaling power of grades has attenuated little, if at all.

    Introduction: There is ambiguity in pathological grading of high grade gliomas within the WHO 2000 classification, especially those with predominant oligodendroglial differentiation. Patients and methods: All adult high grade gliomas treated radically, 1996-2005, were assessed. Cases in which pathology was grade III but radiology suggested glioblastoma (GBM) were classified as 'grade III/IV'; their pathology was reviewed. Results: Data from 245 patients (52 grade III, 18 grade III/IV, 175 GBM) were analysed using a Cox Proportional Hazards model. On pathology review, features suggestive of more aggressive behaviour were found in all 18 grade III/IV tumours. Oligodendroglial components with both necrosis and microvascular proliferation were present in 7. MIB-1 counts for the last 8 were all above 14%, mean 27%. Median survivals were: grade III 34 months, grade III/IV 10 months, GBM 11 months. Survival was not significantly different between grade III/IV and GBM. Patients with grade III/IV tumours had significantly worse outcome than grade III, with a hazard of death 3.7 times higher. Conclusions: The results highlight the current inconsistency in pathological grading of high grade tumours, especially those with oligodendroglial elements. Patients with histological grade III tumours but radiological appearances suggestive of GBM should be managed as glioblastoma

    This paper explores the development of the urban forest in East Jakarta. By 2030 Jakarta area has a target of 30% green area covering 19,845 hectares, including urban forest covering an area of 4,631 hectares. In 2015, the city forest is only 646 hectares, while the city requires 3,985 hectares of new land Urban forest growth from year to year showed a marked decrease with increasing land area awoke to commercial functions, environmental conditions encourage the development of the city to become unsustainable. This research aims to support sustainable urban development and ecological balance through the revitalization of green areas and urban development. Analytical methods for urban forest area is calculated based on the amount of CO2 that comes from people, vehicles, and industrial. Urban spatial analysis based on satellite image data, using a GIS program is an analysis tool to determine the distribution and growth patterns of green areas. This paper uses a dynamic system model to simulate the conditions of the region against intervention to be performed on potential areas for development of urban forests. The result is a model urban forest area is integrated with a social and economic function to encourage the development of sustainable cities.

    Wade-Lyles, Terri A.

    In a large urban district in Ohio, 29.2% of Grade 5, 28.7% of Grade 8, and 45.7% of Grade 10 students passed the state test in science. School district administrators formed a community partnership with local science institutions in order to provide students with hands-on place-based learning experiences intended to improve science academic achievement in PK-Grade 5. The purpose of this qualitative program evaluation was to determine the level of implementation of that place-based program by examining the efficacy of the teachers' embedded professional development and their experiences with the training components. Bruner's theory of cognitive development was used to examine teachers' needs in facilitating the program. A stratified random sample of 659 PK-Grade 5 teachers from 73 district elementary schools was selected, and 57 teachers responded to an anonymous online survey of 5 open-ended questions. Data were analyzed using thematic analysis to identity factors that enhanced or impeded the implementation of place-based education programming based on their professional development. The key findings indicated that over half of the participants viewed resources as lacking, training as limited, and planning that is too time consuming, and complicated. Participants expressed the need for clarity regarding resources and more training on how to plan for and integrate the placed-based approach. The resulting project was an executive summary and interactive workshop for program stakeholders, such as administrators, teachers, and ultimately students, who would benefit from this project by improving the place-based program.

  7. Teen Culture, Technology and Literacy Instruction: Urban Adolescent Students’ Perspectives

    Full Text Available Modern teens have pervasively integrated new technologies into their lives, and technology has become an important component of teen popular culture. Educators have pointed out the promise of exploiting technology to enhance students’ language and literacy skills and general academic success. However, there is no consensus on the effect of technology on teens, and scant literature is available that incorporates the perspective of urban and linguistically diverse students on the feasibility of applying new technologies in teaching and learning literacy in intact classrooms. This paper reports urban adolescents’ perspectives on the use of technology within teen culture, for learning in general and for literacy instruction in particular. Focus group interviews were conducted among linguistically diverse urban students in grades 6, 7 and 8 in a lower income neighborhood in the Northeastern region of the United States. The major findings of the study were that 1 urban teens primarily and almost exclusively used social media and technology devices for peer socializing, 2 they were interested in using technology to improve their literacy skills, but did not appear to voluntarily or independently integrate technology into learning, and 3 8th graders were considerably more sophisticated in their use of technology and their suggestions for application of technology to literacy learning than 6th and 7th graders. These findings lead to suggestions for developing effective literacy instruction using new technologies.

  9. Rural-urban migration and child survival in urban Bangladesh: are the urban migrants and poor disadvantaged?

    2008-01-01

    This paper analyses the levels and trends of childhood mortality in urban Bangladesh, and examines whether children's survival chances are poorer among the urban migrants and urban poor. It also examines the determinants of child survival in urban Bangladesh. Data come from the 1999-2000 Bangladesh Demographic and Health Survey. The results indicate that, although the indices of infant and child mortality are consistently better in urban areas, the urban-rural differentials in childhood mortality have diminished in recent years. The study identifies two distinct child morality regimes in urban Bangladesh: one for urban natives and one for rural-urban migrants. Under-five mortality is higher among children born to urban migrants compared with children born to life-long urban natives (102 and 62 per 1000 live births, respectively). The migrant-native mortality differentials more-or-less correspond with the differences in socioeconomic status. Like childhood mortality rates, rural-urban migrants seem to be moderately disadvantaged by economic status compared with their urban native counterparts. Within the urban areas, the child survival status is even worse among the migrant poor than among the average urban poor, especially recent migrants. This poor-non-poor differential in childhood mortality is higher in urban areas than in rural areas. The study findings indicate that rapid growth of the urban population in recent years due to rural-to-urban migration, coupled with higher risk of mortality among migrant's children, may be considered as one of the major explanations for slower decline in under-five mortality in urban Bangladesh, thus diminishing urban-rural differentials in childhood mortality in Bangladesh. The study demonstrates that housing conditions and access to safe drinking water and hygienic toilet facilities are the most critical determinants of child survival in urban areas, even after controlling for migration status. The findings of the study may

    Kerner, R.

    1983-01-01

    The mathematical background for a graded extension of gauge theories is investigated. After discussing the general properties of graded Lie algebras and what may serve as a model for a graded Lie group, the graded fiber bundle is constructed. Its basis manifold is supposed to be the so-called superspace, i.e. the product of the Minkowskian space-time with the Grassmann algebra spanned by the anticommuting Lorentz spinors; the vertical subspaces tangent to the fibers are isomorphic with the graded extension of the SU(N) Lie algebra. The connection and curvature are defined then on this bundle; the two different gradings are either independent of each other, or may be unified in one common grading, which is equivalent to the choice of the spin-statistics dependence. The Yang-Mills lagrangian is investigated in the simplified case. The conformal symmetry breaking is discussed, as well as some other physical consequences of the model. (orig.)

  14. Finding Urban Identity through Culture-led Urban Regeneration

    Directory of Open Access Journals (Sweden)

    Kyu Hong Hwang

    Full Text Available ABSTRACT: A city experiencing a cycle from growth to decline cannot maintain sustainable development without the type of urban identity that could be consolidated by culture-led urban regeneration. A plan for urban regeneration in a declining urban area should be practiced partially or on the whole according to the characteristics of the community. By transforming a low-value and deteriorated area into a highly valued district, the local community can simultaneously restore its social pride, revive the local economy, and realize an urban identity.Firstly, this paper examines urban decline in order to better understand urban regeneration and the need for multidisciplinary management, and also, by considering the necessity for and universal types of urban regeneration, investigates the characteristics of culture-led urban regeneration as a tool for realizing socio-economic revival and urban identity. In particular, this study suggests the action techniques and benchmarking points for urban regeneration by analyzing cases of culture-led urban regeneration in Korea. Three subjects were considered as case studies in this paper: 1 Hanok village in Jeonju city, which changed from a twilight zone to a tourist attraction; 2 Changdong district in Changwon city, which recovered from an area of declining and dark alleyways that had been the hub for arts and culture in the 1970s to become a new artist village; and 3 Cheongju city, which is being transformed from an idle industrial facility into a cultural space. This thesis suggests the implementation process of culture-led urban regeneration to find an urban identity through analysis of the causes of urban decline, the methods of regeneration, and the results of urban regeneration in the three aforementioned cases. In the conclusion section of this paper, the implementation process for culture-led urban regeneration is summarized as consisting of 5 phases: Phase 1, the diagnosis of decline; Phase 2

    2017-09-01

    Urban expansion displays different characteristics in each period. From the perspective of the urban agglomeration, studying the spatial and temporal characteristics of urban expansion plays an important role in understanding the complex relationship between urban expansion and network structure of urban agglomeration. We analyze urban expansion in the Yangtze River Delta Urban Agglomeration (YRD) through accessibility to and spatial interaction intensity from core cities as well as accessibility of road network. Results show that: (1) Correlation between urban expansion intensity and spatial indicators such as location and space syntax variables is remarkable and positive, while it decreases after rapid expansion. (2) Urban expansion velocity displays a positive correlation with spatial indicators mentioned above in the first (1980-1990) and second (1990-2000) period. However, it exhibits a negative relationship in the third period (2000-2010), i.e., cities located in the periphery of urban agglomeration developing more quickly. Consequently, the hypothesis of convergence of urban expansion in rapid expansion stage is put forward. (3) Results of Zipf's law and Gibrat's law show urban expansion in YRD displays a convergent trend in rapid expansion stage, small and medium-sized cities growing faster. This study shows that spatial linkage plays an important but evolving role in urban expansion within the urban agglomeration. In addition, it serves as a reference to the planning of Yangtze River Delta Urban Agglomeration and regulation of urban expansion of other urban agglomerations.

  20. Feeding holy bodies: A study on the social meanings of a vegetarian diet to Seventh-day Adventist church pioneers

    Directory of Open Access Journals (Sweden)

    Ruben Sánchez

    2016-06-01

    Full Text Available Ten years ago National Geographic magazine reported that the Loma Linda Seventh-day Adventist population is one of the communities in the world that lives longer and with a higher quality of life thanks in part to the biological benefits of a vegetarian diet. Along with National Geographic, other media outlets have reported since then that the Adventist religious community considers a plant-based diet a very important factor for a healthy lifestyle. Adventists have been promoting this type of diet worldwide for more than 150 years. This article is an attempt to understand from a social-scientific perspective the origin of the importance they lend to diet and see whether this helps explain why approximately 150 years after the founding of the church, diet remains crucial for Adventists around the world. The conclusion proposed is that Adventists understood the adoption of a plant-based diet as a special divine instruction in order to nourish their new identity as a special people differentiated from the rest of society. This was possible through a desecularisation of diet that placed food in the moral category of the Adventist belief system.

    Urban research in many countries has failed to keep up with the pace of rapidly and constantly evolving urban change. The growth of cities, the increasing complexity of their functions and the complex intra- and inter-urban linkages in this 'urban century' demand new approaches to urban analysis, which, from a systemic perspective, supersede the existing fragmentation in urban studies. In this paper we propose the concept of the urban piazza as a framework in order to address some of the inefficiencies associated with current urban analysis. By combining wealth-creating potential with smart urban mobility, ecological resilience and social buzz in this integrated and systemic framework, the aim is to set the basis for a ' New Urban World ' research blueprint, which lays the foundation for a broader and more integrated research programme for strategic urban issues.

    Fahem, A K

    1993-03-01

    Mauritania had been a country of nomads traveling long distances to water holes, cemeteries, and oases. A teacher was responsible for teaching young children about the Koran. The best students attended a traveling university to receive personalized teaching at a higher level. Between 1965 and 1988, the spatial distribution of the population changed considerably (nomads, 78% vs. 12%; settled rural dwellers, 15% vs. 41% [45% in 1977]; urban dwellers, 8% vs. 47%). The leading reasons for a settled life, especially in 1965-1980, were desertification and aridity and their effects on water sources and grazing lands. Other contributing factors included iron and copper mining, creation of new states after the war in the Western Sahara, birth of new towns (e.g., the capital Nouakchott), and suppression of slavery. Urbanization grew 10%/year (20%/year for Nouakchott between 1962-1977) after independence. The new towns were mining and industrial centers. Spatial redistribution of the population is a vast and fruitful subject to include in teaching curricula at all levels (primary, secondary, and postsecondary) and for almost all disciplines (e.g., geography, history, civics, and mathematics). The author has provided a model curriculum for grades 1 through 6 of primary school. For example, contents for 6th grade history and geography include causes for the shift from a nomadic lifestyle to a sedentary lifestyle and urbanization, impact on the family and the environment, international migrations, and case study of a town. The author also lists comprehensive knowledge, proficiency, and behavior objectives. Behavior objectives are: participant in manual activities and agricultural work; help uprooted classmates better integrate themselves in a new welcoming milieu; support rural development efforts; and preserve or strengthen links between the city and rural areas through exchange visits and correspondence.

    <正>1. Concept comparison of urban cultural heritage management and urban planning management 1.1 Urban cultural heritage managementUrban cultural heritage management is an important component of cultural heritage management which is a systematic conser-vation to maintain the cultural value of cul-tural heritages so as to meet the enjoyment demand of the current or future generations. At present, the cultural heritage conserva-tion principles have been defined by many worldwide laws or charters, such as the Venice Charter of ICOMOS, the UNESCO World Heritage Convention, etc., and have been brought into legislation or policies in many countries. The fi nal goal of urban cul-tural heritage management is to find a real sustainable approach to manage heritages, which could benefit the heritages them-selves, the heritage managers and the local communities as well. Cultural heritage man-agement includes the management of urban cultural heritages, that of natural heritages in non-urban areas and that of intangible cultural heritages.1.2 Urban planning managementUrban planning management is a type of urban management. From the practical viewpoint, urban management should be an overall management which includes urban planning management, urban infrastructure and public facility management, urban en-vironment and public order management, etc., takes urban infrastructures and public resources as management object, and ischaracterized by the goal of exerting the comprehensive effects of economy, society and environment. While from the techni-cal viewpoint, urban planning management refers to the planning management executed by urban governments based on the relevant laws and regulations, including the manage-ment of urban land-use and that of different types of constructions. It actually means the organizing, guiding, controlling and coordinating process focusing on different construction projects in cities. The urban cultural heritage mentioned here includes all the physical

    Full Text Available The issues of urban and urbanization emerged after the industrial revolution. Thus, cities that have increased rapidly in population have become points of attraction for people. Over the past century, the world population has begun to gather quickly in urban areas. Cities are transforming into unhealthy living environments with distorted ecological balance, lost green areas and aesthetic qualities. The value of accessible green spaces in urban areas is increasing to the unprecedented levels. The green space system seen as a necessity in the cities have provided the emergence of the "urban landscape" phenomenon. The issue of urban landscape is now a very serious concept. The landscape change is moving along with the level of civilization. Primarily, guidance service should be offered for more efficient, comfortable and protective areas. An interdisciplinary approach is needed in the creation of urban spaces. In this study, the term of urban landscape was explained and the researches about the contributions of urban landscape to urban life were examined and suggestions were made about the subject.

  9. Will bottle-grade PET demand lure fiber-grade capacity?

    International Nuclear Information System (INIS)

    Coeyman, M.

    1993-01-01

    As demand for bottle-grade polyethylene terephthalate (PET) continues strong and new capacity hastens to meet it, some industry observers wonder if conversions to bottle-grade from fiber-grade capacity will become an industry trend. Taiwan's Nan Ya Plastics was recently said to be considering such a switch, but company sources say it has no such plans. Peter Driscoll, senior partner at PCI Fibres ampersand Raw Materials (Crawley, UK), says that while it is true that demand for the bottle-grade material remains unsatisfied, he doubts that many conversions will take place. You must remember, says Driscoll, that it is not always possible to switch, and that even where it is possible there are limitations

    In Malaysia, urban farming is viewed as a catalyst towards achieving the well-being of urban dwellers and natural environment. Urban farming is a strategy for Malaysia’s food and economic security, and as one of the foci in the agriculture transformation whereby urban dwellers are encouraged to participate in this activity. Previous study proved that urban farming can help to address social problems of food security, urban poverty and high living cost, also provides leisure and recreation among urban dwellers. Thus, this study investigates the best urban farming practices suitable for urban setting, environment and culture of urban dwellers. Data collection was done via questionnaire survey to urban farmers of a selected community garden in Subang Jaya, Selangor. Meanwhile, on-site observations were carried out on gardening activities and the gardens’ physical attributes. The study sample encompasses of 131 urban farmers of 22 community gardens in Subang Jaya. It was found that most of the community gardens practiced crops planting on the ground or soil base planting and dwellers in the lower income group with monthly low household income constitutes the majority (83.2%) of the respondents. Social and health benefits are the highest motivating factors for urban farmers. This study provides unprecedented insights on urban farming practices and motivations in a Malaysian setting.

    We examined the perspectives of low-income, urban youth about the corner store experience to inform the development of corner store interventions. Focus groups were conducted to understand youth perceptions regarding their early shopping experiences, the process of store selection, reasons for shopping in a corner store, parental guidance about corner stores, and what their ideal, or "dream corner store" would look like. Thematic analysis was employed to identify themes using ATLAS.ti (version 6.1, 2010, ATLAS.ti GmbH) and Excel (version 2010, Microsoft Corp). Focus groups were conducted in nine kindergarten-through-grade 8 (K-8) public schools in low-income neighborhoods with 40 fourth- to sixth-graders with a mean age of 10.9±0.8 years. Youth report going to corner stores with family members at an early age. By second and third grades, a growing number of youth reported shopping unaccompanied by an older sibling or adult. Youth reported that the products sold in stores were the key reason they choose a specific store. A small number of youth said their parents offered guidance on their corner store purchases. When youth were asked what their dream corner store would look like, they mentioned wanting a combination of healthy and less-healthy foods. These data suggest that, among low-income, urban youth, corner store shopping starts at a very young age and that product, price, and location are key factors that affect corner store selection. The data also suggest that few parents offer guidance about corner store purchases, and youth are receptive to having healthier items in corner stores. Corner store intervention efforts should target young children and their parents/caregivers and aim to increase the availability of affordable, healthier products.

    2018-04-01

    Due to urbanization, urban areas are shrinking green spaces and increasing concrete, asphalt pavement. So urban climates are different from non-urban areas. In addition, long-term macroscopic studies of urban climate change are becoming more important as global urbanization affects global warming. To do this, it is necessary to analyze the effect of urbanization on the temporal change in urban temperature with the same temperature data and standards for urban areas around the world. In this study, time series analysis was performed with the maximum, minimum, mean and standard values of surface temperature during the from 1980 to 2010 and analyzed the effect of urbanization through linear regression analysis with variables (population, night light, NDVI, urban area). As a result, the minimum value of the surface temperature of the urban area reflects an increase by a rate of 0.28K decade-1 over the past 31 years, the maximum value reflects an increase by a rate of 0.372K decade-1, the mean value reflects an increase by a rate of 0.208 decade-1, and the standard deviation reflects a decrease by rate of 0.023K decade-1. And the change of surface temperature in urban areas is affected by urbanization related to land cover such as decrease of greenery and increase of pavement area, but socioeconomic variables are less influential than NDVI in this study. This study are expected to provide an approach to future research and policy-planning for urban temperature change and urbanization impacts.

    2007-01-01

    As a result of population pressures, hillsides in the world's urban areas are being developed at an accelerating rate. This development increases the risk for urban landslides triggered by rainfall or earthquake activity. To counter this risk, four approaches have been employed by landslide managers and urban planners: (1) restricting development in landslide-prone areas; (2) implementing and enforcing excavation, grading, and construction codes; (3) protecting existing developments by physical mitigation measures and (4) developing and installing monitoring and warning systems. Where they have been utilized, these approaches generally have been effective in reducing the risk due to landslide hazards. In addition to these practices, landslide insurance holds promise as a mitigative measure by reducing the financial impact of landslides on individual property owners. Until recently, however, such insurance has not been widely available and, where it is available, it is so expensive that it has been little used. ?? Springer-Verlag 2006.

  19. Beyond urban penalty and urban sprawl: back to living conditions as the focus of urban health.

    Freudenberg, Nicholas; Galea, Sandro; Vlahov, David

    2005-02-01

    Researchers have long studied urban health, both to describe the consequences of urban living and to design interventions to promote the health of people living in cities. Two approaches to understanding the impact of cities on health have been dominant, namely, urban health penalty and urban sprawl. The urban penalty approach posits that cities concentrate poor people and expose them to unhealthy physical and social environments. Urban sprawl focuses on the adverse health and environmental effects of urban growth into outlying areas. We propose a model that integrates these approaches and emphasizes urban living conditions as the primary determinant of health. The aim of the model is to move beyond describing the health-related characteristics of various urban populations towards identifying opportunities for intervention. Such a shift in framework enables meaningful comparisons that can inform public health activities at the appropriate level and evaluate their effectiveness in improving the health of urban populations. The model is illustrated with two examples from current urban public health practice.

    1996-06-15

    From a cohort of white, non-Hispanic California Seventh-day Adventists, 99 subjects over age 75 years in 1991 were randomly selected. Dietary habits and educational status had been measured in 1976. Subjects completed the Mini-Mental State Examination (MMSE) in 1991, and at that time, they or caregivers also gave information on current medical problems and drug therapy. Those who ate more calories in 1976 had lower MMSE scores in 1991 (p = 0.03), an association strengthened by excluding those with previous stroke or Parkinson's disease by 1991. This raises the possibility that higher consumption of calories in middle age may accelerate the decline in cognitive function seen with aging, as apparently occurs in some animals. Less-educated subjects had lower MMSE scores, especially among the very elderly. The statistical model predicts that the negative association between use of psychotropic drugs and MMSE score (p = 0.004) is particularly potent in those cognitively impaired for other reasons. If causal, this suggests that physicians should use these agents very cautiously in such subjects.

    A perceptual bias, the third person effect, has been observed where individuals believe themselves to differ from others regarding the perceived influence of media messages. Given the frequency with which youth encounter prosmoking messages and the reported negative effects of these messages, it is of value to study whether youth perceive cigarette advertisements to influence themselves and their friends and peers. This study examined the associations between exposure to social and information prosmoking environments, the perceived influence of cigarette advertisements on self, best friends, and other youth, and smoking susceptibility. A sample of 571 seventh graders completed surveys on tobacco advertisements and promotions. Using Student's-t, chi-square, ANOVA tests and proportional odds models, we found significant associations between perceived influence of cigarette advertisements and exposure to social and information prosmoking environments as well as smoking susceptibility. These data suggest that youth be taught that everyone is vulnerable to the tobacco industry's strategies and be given skills to resist prosmoking advertising.

    The relationship between dietary nutrients and plasma testosterone, 5 alpha-dihydrotestosterone, estradiol-17 beta, luteinizing hormone, and prolactin levels was investigated in 12 Seventh-Day Adventist (SDA) vegetarian (SV), 10 SDA nonvegetarian (SNV), and 8 non-SDA nonvegetarian (NV) men. Fasting blood samples and 3-day dietary intake information were obtained from each subject. The SV subjects consumed significantly more crude and dietary fiber than the SNV and NV subjects, respectively. Plasma levels of testosterone and estradiol-17 beta were significantly lower in the SV than in the omnivores. Additionally, the plasma levels of testosterone and estradiol-17 beta of the combined groups (SV, SNV, and NV) revealed a significant negative relationship with their crude and dietary fiber intakes. These subjects hormonal milieu was related to specific dietary constituents, possibly leading to a decreased plasma concentration of androgen and estrogen in vegetarians. Implications include the possible modification of prostate cancer risk through dietary intervention.

    2010-06-01

    A new grading system for bladder cancer (BCa) was adopted in 2004 to reduce observer variability and provide better prognostic information. We compared the World Health Organization (WHO) 1973 and 2004 systems for observer variability and prognosis. Slides of 173 primary non-muscle-invasive BCa were reviewed two times by four pathologists. Intra- and interobserver variability were assessed using κ statistics. We determined the mean grade (eg, G1/low malignant potential is 1 grade point, G2/low grade is 2 grade points) of the pathologists per grading cycle. Kaplan-Meier analyses were applied for prediction of recurrence and progression. For WHO 2004 and 1973 grading, the agreement between the pathologists was 39-74% (κ: 0.14-0.58) and 39-64% (κ: 0.15-0.41), respectively. The intraobserver agreement varied from 71% to 88% (κ: 0.55-0.81). The mean grade of a pathologist was constant (difference below 0.1 grade point) irrespective of the grading system. Conversely, mean-grade differences among the pathologists were high, up to 0.7 grade point. The mean grades for the WHO 2004 system were 0.3-0.5 grade point higher than those of WHO 1973. Mean grade distinguished low and high graders among the pathologists and was strongly linked with risk of progression in each grade category. The variation in mean grade among individual pathologists exceeded the grade shift caused by WHO 2004 grading. Knowledge of the pathologist's mean grade allows a better assessment of the prognostic value of grading. Mean grade has the potential to become a tool for quality assurance in pathology.

    1991-04-01

    The Adventist Health Study, a cohort study of 34,198 California Seventh-day Adventists, identified 61 cases of new primary lung cancer over 6 years of follow-up (1977-1982). The population studied was unique in that only 4% admitted to current cigarette smoking and about half were lacto-ovovegetarians. A total of 36% of the lung tumors were adenocarcinomas, and 19% were squamous cell carcinomas. The expected associations with cigarette smoking were noted for Kreyberg group I tumors (squamous cell, large cell, and small cell carcinoma; relative risk (RR) = 53.2 for current smokers and 7.07 for past smokers), but much lesser associations were noted for Kreyberg group II tumors (adenocarcinoma and bronchoalveolar carcinoma; RR = 1.99 for current smokers and 1.59 for past smokers). In this study, fruit consumption was the dietary constituent that showed a strong, statistically significant protective association with lung cancer that was independent of smoking (fruit consumption less than 3 times/week, RR = 1.0; 3-7 times/week, RR = 0.30; greater than or equal to 2 times/day, RR = 0.26). This association was somewhat stronger for Kreyberg group II tumors, but similar trends were also noted for Kreyberg group I tumors. Confounding with smoking seems unlikely in a population with very few current smokers and where both stratification and Cox modeling methods of analysis led to similar conclusions.

    The average bond energies D(gm)(B-Z) for boron-containing molecules have been calculated by the Pauling geometric-mean equation. These calculated bond energies are compared with the average bond energies D(exp)(B-Z) obtained from experimental data. The higher values of D(exp)(B-Z) in comparison with D(gm)(B-Z) when Z is an element in the fifth, sixth, or seventh periodic group may be attributed to resonance stabilization or double-bond character.

    Full Text Available The present paper attempted to study the urbanization in India and condition of urban slums in terms of water, sanitation, electricity, garbage collection and health care, and education which are supposed to be basic minimum needs for the slum dwellers. India is going through the process of rapid urbanization because of industrialization like other third world countries.  The percent of urbanization increase from 27.8 percent in 2001 to 31.1 percent in 2011 census. The increase in the percentage of population in urban areas is because of natural growth, rural to urban migration and the reclassification of village and towns. The share of the slum population in the total urban population of the country was 18.3 percent in 2001 while in 2011 it was 17.4 percent. The condition of urban slums in India is to be improved so as to make them better for living.

    Aim: To compare the reliability of the conventional ultrasonography grading system for hydronephrosis as suggested by the Society for Fetal Urology (SFU) in 1993 and that developed by Onen in 2007. Materials and methods: One hundred and eighty kidneys in 90 paediatric patients were assessed by four radiologists using each of the two grading systems twice. The SFU system was graded 0–4 (0 = no hydronephrosis; 1 = visualized only renal pelvis; 2 = plus a few caliceal dilatation; 3 = all calyceal dilatation; 4 = plus parenchymal thinning). The Onen system was graded 0–4 (0 = no hydronephrosis; 1 = only renal pelvic dilatation; 2 = plus caliceal dilatation; 3 = plus 50% renal parenchymal loss). Cohen's kappa statistic was used to estimate intra- and interobserver agreement. The weighted least-squares approach was used to compare the intra-observer agreement, and bootstrapping was used to compare the interobserver agreement between the two systems. Results: Intra-observer agreement was substantial to almost perfect in both the SFU (κ 0.79–0.95) and the Onen (κ 0.66–0.97) grading system without difference. The overall interobserver agreement was substantial in both the SFU (κ 0.61–0.68) and the Onen (κ 0.66–0.76) grading system. However, interobserver agreement was fair to moderate for SFU grades 1 and 2 and Onen grades 2 and 3. Conclusion: Both the SFU and Onen grading system are reliable with good intra- and interobserver agreement. However, decreased interobserver agreement was demonstrated for SFU grades 1 and 2 and Onen grades 2 and 3

  13. Application of Microbial Technology Used in Bioremediation of Urban Polluted River: A Case Study of Chengnan River, China

    2018-05-01

    Full Text Available Contrary to the constraints in time, investment, and management of the traditional technology for waste water treatment, this paper seeks to propose a more advanced, reliable, and affordable new technology to restore urban polluted rivers to pristine quality levels. The paper also presents new ideas on the selection and use of microbial agents to improve the efficiency of pollution removal. It presents the successful implementation of microbial technology (MT on Chengnan River, which was heavily polluted before MT implementation. Without artificial aeration, sediment dredging, or complete sewage interception, we directly sprayed a previously configured HP-RPe-3 Microbial Agent into the water body and sediment. We considered the feasibility of MT for treating polluted urban rivers from the perspective of several water quality indices evaluation methods. After the treatment, the concentration of dissolved oxygen (DO reached 5.0 mg/L, the removal rates of ammonia nitrogen (NH3-N and chemical oxygen demand (COD reached 20% and 38% respectively, and the average degradation rate of total phosphorus (TP along river was close to 15%. Also, the Nemerow Index of the river was reduced from 2.7 to 1.9. The Fuzzy Comprehensive Index shows a tendency for improvement from Inferior Grade V to a better grade (approximately Grade III. The color of the river water changed, from black or dark green, to its original color. The results indicate that the bioremediation technology of directly adding microbial agents mainly aimed for the degradation of NH3-N can preliminarily eliminate the black-odor phenomenon of urban rivers, and improve their water quality. It is expected that the MT application, and the concept of how to select the corresponding microbial agents according to main pollutants, can be widely accepted and applied to similar cases.

  14. Urban blight and urban redesign

    The phenomenon of urban blight dates back to the 19th century when industrialisation starting in Europe and North America initiated an uncontrolled urban growth in combination with strong demand in cheap an quickly constructed housing. Ghettoisation of mainly the working-class population and other “marginal groups” were the consequence together with a constant decay of single buildings, whole blocks and quarters. These general aspects of urban blight with its additional facettes or aspects re...

    Scholars call for more attention to how marginalization influences the development of low-income and racial/ethnic minority youth and emphasize the importance of youth's subjective perceptions of contexts. This study examines how beliefs about the fairness of the American system (system justification) in sixth grade influence trajectories of self-esteem and behavior among 257 early adolescents (average age 11.4) from a diverse, low-income, middle school in an urban southwestern city. System justification was associated with higher self-esteem, less delinquent behavior, and better classroom behavior in sixth grade but worse trajectories of these outcomes from sixth to eighth grade. These findings provide novel evidence that system-justifying beliefs undermine the well-being of marginalized youth and that early adolescence is a critical developmental period for this process. © 2017 The Authors.

    2015-05-01

    In the past decades, China has observed rapid urbanization, the nation's urban population reached 50% in 2000, and is still in steady increase. Rapid urbanization in China has an adverse impact on urban hydrological processes, particularly in increasing the urban flood risks and causing serious urban flooding losses. Urban flooding also increases health risks such as causing epidemic disease break out, polluting drinking water and damaging the living environment. In the highly urbanized area, non-engineering measurement is the main way for managing urban flood risk, such as flood risk warning. There is no mature method and pilot study for urban flood risk warning, the purpose of this study is to propose the urban flood risk warning method for the rapidly urbanized Chinese cities. This paper first presented an urban flood forecasting model, which produces urban flood inundation index for urban flood risk warning. The model has 5 modules. The drainage system and grid dividing module divides the whole city terrain into drainage systems according to its first-order river system, and delineates the drainage system into grids based on the spatial structure with irregular gridding technique; the precipitation assimilation module assimilates precipitation for every grids which is used as the model input, which could either be the radar based precipitation estimation or interpolated one from rain gauges; runoff production module classifies the surface into pervious and impervious surface, and employs different methods to calculate the runoff respectively; surface runoff routing module routes the surface runoff and determines the inundation index. The routing on surface grid is calculated according to the two dimensional shallow water unsteady flow algorithm, the routing on land channel and special channel is calculated according to the one dimensional unsteady flow algorithm. This paper then proposed the urban flood risk warning method that is called DPSIR model based

    To develop the national neglect norms for urban primary school students in China. According to multi-stage stratified cluster sampling principle, 24 cities of 13 provinces (municipalities) in China were selected during December 1 to 31, 2008. A total of 1491 students in grade 1 - 3 and 2236 students in grade 4 - 6 were selected. Questionnaire was designed by authors and the final norms were determined through several statistical analysis methods, such as item analysis method, factor analysis method, reliability analysis method. The reliability analysis and validity analysis were used to test the stability and reliability of the norms. The evaluation criteria of the scale was determined by the percentile method, then the initial development of the norm was completed. The two questionnaires of grade 1 - 3 and grade 4 - 6 students consisted of 55 and 57 items, respectively, whose item loadings were ranged from 0.301 to 0.687 and 0.321 to 0.730, which met the statistical requirements. For grade 1 - 3 students, the scale's total Cronbach α coefficients was 0.914, the total split-half reliability coefficients was 0.896, the Cronbach α coefficients of four level was above 0.737 except medical and social neglect, split-half reliability was ranged from 0.461 to 0.757; for grade 4-6 students, the scale's total Cronbach α coefficients was 0.916, split-half reliability was 0.883, except social neglect, the Cronbach α coefficients of other level was ranged 0.457 to 0.856, split-half reliability was ranged from 0.500 to 0.798. The total neglect cut-off score of the two scales grade 1-3 and 4-6 were 125 and 155, respectively. The structure of two norms was reasonable. The scales have good stability and reliability.

    Competence with fractions predicts later mathematics achievement, but the codevelopmental pattern between fractions knowledge and mathematics achievement is not well understood. We assessed this codevelopment through examination of the cross-lagged relation between a measure of conceptual knowledge of fractions and mathematics achievement in sixth and seventh grades (N=212). The cross-lagged effects indicated that performance on the sixth grade fractions concepts measure predicted 1-year gains in mathematics achievement (ß=.14, pmathematics achievement did not predict gains on the fractions concepts measure (ß=.03, p>.50). In a follow-up assessment, we demonstrated that measures of fluency with computational fractions significantly predicted seventh grade mathematics achievement above and beyond the influence of fluency in computational whole number arithmetic, performance on number fluency and number line tasks, central executive span, and intelligence. Results provide empirical support for the hypothesis that competence with fractions underlies, in part, subsequent gains in mathematics achievement. Copyright © 2012 Elsevier Inc.

    This article deals with the part of urban climatology which is of particular relevance to human beings. Presented first is a summary of all human biometerologically effective complexes, as well as other factors which are relevant to urban planning and which depend on atmospheric conditions in urban structures in a direct or indirect manner. Later, methods for human biometerologically significant assessment of thermal and air pollution components of the urban climate are discussed in detail, because these components can be strongly influenced by urban planning. The application of these methods is illustrated by some results of appropriate investigations in urban areas.

    2013-07-01

    This study examined relationships between social-emotional skills and involvement in bullying and violence among young adolescents from ethnically diverse, economically disadvantaged urban neighborhoods. Data were from 171 sixth- and seventh-grade students involved in a larger intervention study. Analyses examined relationships between social-emotional skills measures (intrapersonal skills, stress management skills, interpersonal skills) and involvement in violence, physical bullying, and relational aggression. Of social-emotional skills indicators, interpersonal skills and stress management skills demonstrated significant bivariate relationships with each of the bullying and violence outcomes. In multivariate models, greater interpersonal skills and greater stress management skills were significantly associated with lower odds of violence involvement. Greater stress management skills were also significantly associated with lower levels of physical bullying and relational aggression. Findings suggest that efforts to foster development of young adolescents' social-emotional skills may, in turn, reduce their risk for involvement in bullying and violence.

    The purpose of this study was to examine the determinants of benefits and barriers and their relationship with physical activity (PA) among predominantly Latino middle school students. Data were collected in a cross-sectional survey of 4,773 seventh-grade students recruited from a large, urban school district in Los Angeles. Hierarchical logistic regression models were used to assess determinants of benefits and barriers as well as their association with self-reported PA. Differences in benefits and barriers were observed by gender, ethnicity, and body size. Barriers were negatively correlated with all three PA outcomes while benefits were positively associated with exercising at least 60 min daily. A deeper understanding of benefits and barriers can facilitate the development of interventions and collaborative efforts among physical education teachers, school nurses, and administrators to implement comprehensive approaches that encourage students' participation in PA inside and outside of the classroom.

  11. Urban Agriculture, Commons and Urban Policies: Scaling up Local Innovation

    Directory of Open Access Journals (Sweden)

    François Mancebo

    2016-04-01

    Full Text Available May urban agriculture be the cornerstone that helps reconfigure more sustainable cities and if so, under which conditions? And if so, what type of urban agriculture? Such are the two issues underlying this article. Why not counteracting urban sprawl by fostering what could be called “rural sprawl”, by introducing nature and rural characteristics such as farming within the city, in its interstitial areas and wastelands? In this perspective, urban agriculture becomes a common good, bringing people together and reshaping the whole urban fabric that would eventually propose a radical remaking of the urban. Urban agriculture lends particularly well to long-lasting urban policies, especially those turning environmental “bads”—such as brownfields and wastelands—into environmental “goods” and urban amenities. Urban agriculture in interstitial abandoned urban areas may be one of cities’ main seedbeds of creative innovation. It is all about the right to decide and the power to create, renewing and deepening what Henri Lefebvre called The Right to the City.

  13. Thinking Together Urban Conservation With Urban Modernization In The Process Of Urban Transformation: The Possibilities Of "Historic Urban Landscape" Concept

    Directory of Open Access Journals (Sweden)

    İclal Dinçer

    2013-06-01

    Full Text Available Today, the big cities that are centers of innovation and creativity offer employment and training opportunities for people on the one hand, and are faced to face to uncontrolled urbanization on the other. One of the main problems of these cities is socio-cultural and spatial harmony between urban heritage and new developments. It should be recognized that it is difficult to preserve both the tangible and intangible heritage and sustainable development together with providing the quality of urban life. This article will discuss the "historic urban landscape" concept that is one of the approaches in the long term evolution of conservation and reconstruction of cities. In this evolution process, concepts of urban conservation, environmenta protection, urban archaeology, cultural landscape and the value o cultural heritage for society are the important milestones. Within this approach "historic urban landscape", decision-making processes needs to evolve towards the partnerships of state, market and civil society actors through negotiation and cooperation between them. In the article three examples from Istanbul are examined.

    This study aimed to examine whether intrinsic motivation and behavioral self-regulation are related to physical activity during middle school. Structural equation modeling was applied in cross-sectional and longitudinal tests of self-determination theory. Consistent with theory, hypothesized relations among variables were supported. Integrated regulation and intrinsic motivation were most strongly correlated with moderate-to-vigorous physical activity measured by an accelerometer. Results were independent of a measure of biological maturity. Construct validity and equivalence of measures were confirmed longitudinally between the sixth and seventh grades and between boys and girls, non-Hispanic Black and White children and overweight and normal-weight students. Measures of autonomous motivation (identified, integrated, and intrinsic) were more strongly related to physical activity in the seventh grade than measures of controlled motivation (external and introjected), implying that physical activity became more intrinsically motivating for some girls and boys as they moved through middle school. Nonetheless, change in introjected regulation was related to change in physical activity in the seventh grade, suggesting that internalized social pressures, which can be detrimental to sustained activity and well-being, also became motivating. These results encourage longer prospective studies during childhood and adolescence to clarify how controlled and autonomous motivations for physical activity develop and whether they respond to interventions designed to increase physical activity.

  15. Affective Urbanism

    DEFF Research Database (Denmark)

    Samson, Kristine

    Urban design and architecture are increasingly used as material and affective strategies for setting the scene, for manipulation and the production of urban life: The orchestration of atmospheres, the framing and staging of urban actions, the programming for contemplation, involvement, play......, experience and consumption are all strategic design tools applied by planners and architects. Whereas urban design in former modernist planning served merely functional or political means, urban design has increasingly become an aesthetical mediator of ideologies embedded in the urban field of life forces....... Under these circumstances affective aesthetics operate strategically within the urban field of interests, capital flows and desires of the social. This ‘affective urbanism’ (Anderson & Holden 2008) is linked to a society influenced by new kinds of information flows, where culture is mediated and enacted...

    Full Text Available There is an organic relationship between capitalism and urban space. Thisrelationship is a dynamic one which reproduces and renovates itself constantlyaccording to the conjuncture of each period and which evolves / changes inparallel with the necessities and rationalities of capital accumulation in historicalprocess. Therefore, neither reproduction of capitalist urban space with the regimeof capital accumulation nor the process of restructuring following a crisis in theregime of capital accumulation with spatial organization of capitalism can becompared independently. Today, in the concrete phase that capitalism hasreached, urban space has become one of the most important parts of direct capitalaccumulation under the hegemony of financial capital. In this context, urbantransformation projects and various strategies ofthe process becomes significantwith the instrumentalization of space by capital rationality. However, this processcarries the internal paradoxes of capitalism into the urban space at the same time,and cities, competing as candidates to be financial centres where the capital hasintensified and centralized, also transforms into spaces of violent socialpolarization. At this point, especially the reformation of squatter settlements has astrategic importance in the process of urban transformation and there are attemptsto attach the urban poor, who are the addressee of the process, under a widerurban hegemony project with the strategy of urban renovation.

  19. Changes in Urban Youths' Attitude Towards Science and Perception of a Mobile Science Lab Experience

    Science.gov (United States)

    Fox, Jared

    This dissertation examined changes in urban youth's attitude towards science as well as their perception of the informal science education setting and third space opportunity provided by the BioBus, a mobile science lab. Science education researchers have often suggested that informal science education settings provide one possible way to positively influence student attitude towards science and engage marginalized urban youth within the traditional science classroom (Banks et al., 2007; Hofstein & Rosenfeld, 1996; National Research Council, 2009; Schwarz & Stolow, 2006; Stocklmayer, Rennie, & Gilbert, 2010). However, until now, this possibility has not been explored within the setting of a mobile science lab nor examined using a theoretical framework intent on analyzing how affective outcomes may occur. The merits of this analytical stance were evaluated via observation, attitudinal survey, open-response questionnaire, and interview data collected before and after a mobile science lab experience from a combination of 239 students in Grades 6, 8, 9, 11, and 12 from four different schools within a major Northeastern metropolitan area. Findings from this study suggested that urban youth's attitude towards science changed both positively and negatively in statistically significant ways after a BioBus visit and that the experience itself was highly enjoyable. Furthermore, implications for how to construct a third space within the urban science classroom and the merits of utilizing the theoretical framework developed to analyze cultural tensions between urban youth and school science are discussed. Key Words: Attitude towards science, third space, mobile science lab, urban science education.

    The High Temperature Materials Laboratory (HTML) has completed its seventh year of operation as a designated Department of Energy User Facility at the Oak Ridge National Laboratory. Growth of the User Program has been demonstrated by the number of institutions executing user agreements since the HTML began operation in 1987. A total of 193 nonproprietary agreements (91 industry and 102 university) and 41 proprietary agreements (39 industry and two university) are now in effect. This represents an increase of 21 nonproprietary user agreements during FY 1994. Forty-one states are represented by these users. During FY 1994, the HTML User Program evaluated 106 nonproprietary proposals (46 from industry, 52 from universities, and 8 from other government facilities) and 8 proprietary proposals. The HTML User Advisory Committee approved about ninety-five percent of those evaluated proposals, sometimes after the prospective user revised the proposal based on comments from the Committee. This annual report discusses FY 1994 activities in the individual user centers, as well as plans for the future. It also gives statistics about users and their proposals and FY 1994 publications, and summarizes nonproprietary research projects active in FY 1994.

  3. Using rock art as an alternative science pedagogy

    Science.gov (United States)

    Allen, Casey D.

    College-level and seventh-grade science students were studied to understand the power of a field index, the Rock Art Stability Index (RASI), for student learning about complex biophysical environmental processes. In order to determine if the studied population was representative, 584 college and seventh-grade students undertook a concept mapping exercise after they had learned basic weathering science via in-class lecture. Of this large group, a subset of 322 college students and 13 seventh-grade students also learned RASI through a field experience involving the analysis of rock weathering associated with petroglyphs. After learning weathering through RASI, students completed another concept map. This was a college population where roughly 46% had never taken a "lab science" course and nearly 22% were from minority (non-white) populations. Analysis of student learning through the lens of actor-network theory revealed that when landscape is viewed as process (i.e. many practices), science education embodies both an alternative science philosophy and an alternative materialistic worldview. When RASI components were analyzed after only lecture, student understanding of weathering displayed little connection between weathering form and weathering process. After using RASI in the field however, nearly all students made illustrative concept maps rich in connections between weathering form and weathering process for all subcomponents of RASI. When taken as an aggregate, and measured by an average concept map score, learning increased by almost 14%, Among college minority students, the average score increase approached 23%. Among female students, the average score increase was 16%. For seventh-grade students, scores increased by nearly 36%. After testing for normalcy with Kolmogorov-Smirnov, t-tests reveal that all of these increases were highly statistically significant at p<0.001. The growth in learning weathering science by minority students, as compared to non

    When a college professor who teaches research methods to graduate education students was approached by a local public urban elementary school to help them teach research skills to 4th-graders, it was thought that the process would be simple--take what we did at the college level and differentiate it for the childhood classroom. This article will…

  6. Rural-urban migration and urban unemployment in Nigeria.

    Science.gov (United States)

    Aigbokhan, B E

    1988-01-01

    This paper argues that urban unemployment in Nigeria has been due largely to a failure on the part of the government to pursue policies that reflect commitment on its part to its stated objectives, particularly with regard to employment opportunities. Rural-urban migration has been taking place in the country since the 1960s and at an increasing rate since the 1970s. Economic policies have contributed to this, notably the rural-urban imbalance resulting from the pattern of allocation of public investment expenditures and the wages determination process which tends to concentrate more on the urban sector. These have contributed to the widening urban-rural income differentials. In the face of such migration, the urban industrial sector has been able to absorb only a negligible proportion of migrants. A major factor that has contributed to this is the increased capital-intensity of the sector. Some laudable measures have been introduced this year, notably the establishment of the Directorate of Employment and the Directorate of Food, Road, and Rural infrastructure. The latter, if effectively implemented, should enhance rural income and thereby reduce the rural-urban income gap. The former should reduce the problem of open unemployment. While it is too early to assess the effects of these 2 measures on urban unemployment, they may not improve urban unemployment significantly. There is still the need to design policies to increase labor absorption in general.

    A ~390 GHz harmonic gyrotron based on a cusp electron gun has been designed and numerically modelled. The gyrotron operates at the seventh harmonic of the electron cyclotron frequency with the beam interacting with a TE71 waveguide mode. Theoretical as well as numerical simulation results using the 3D particle-in-cell code MAGIC are presented. The cusp gun generated an axis-encircling, annular shaped electron beam of energy 40 keV, current 1.5 A with a velocity ratio α of 3. Smooth cylindrical waveguides have been studied as the interaction cavities and their cavity Q optimized for 390 GHz operation. In the simulations ~600 W of output power at the design frequency has been demonstrated.

    The next revision to the TNM classification for lung cancer (the seventh edition) is scheduled to be released in 2009. However, the definition of visceral pleural invasion (VPI), which is a non-size-based T2 descriptor, still lacks in detail, and its validation is not included. We analyzed 1046 cases of non-small cell lung cancer (NSCLC) with T1, T2, or T3 diseases from 1990 to 2005, and subclassified into p0-p3 according to the degrees of pleural invasion. Survival analyses were performed using Kaplan-Meier method. Then, all patients were subdivided into nine groups according to tumor size and pleural invasion, and we compared survival differences, primarily focusing on T2a and T2b diseases according to the seventh edition. There was no survival difference between patients with p1 and p2, thus we regarded p1 or p2 as VPI. There was survival difference between two groups, which are expected to be classified as T2b. The behavior of tumors larger than 5cm but 7cm or less with VPI was similar to T3 tumors. VPI is a poor prognostic factor of NSCLC, and the penetration through the elastic layer of the visceral pleura regardless of its exposure on the pleural surface (pl and p2) should be defined as VPI. This study also indicates that VPI influences T stage dependent on tumor size, and it can be suggested that tumors of larger than 5cm but 7cm or less with VPI should be upgraded to T3 stage.

    Belyaev, Vladimir; Feoktistov, Artem; Huygens, Dries; Shamshurina, Eugenia; Golosov, Valentin

    2014-05-01

    Understanding hydrological response and geomorphic behavior of small catchments in urban environments, especially those experiencing urban expansion, represents serious and important problem which has not yet been given an adequate research attention. Urbanization exerts profound and diverse impacts on catchment characteristics, particularly by increasing surface runoff coefficients, peak flow discharges and rates of flash flood waves propagation as a result of widespread appearance of buildings and paved surfaces with practically zero infiltration capacities. Another essential influence of urbanization on small catchment hydrological regimes is associated with significant changes of natural topography (from relatively minor modifications such as grading of steeper slopes to complete transformations including total filling of gullies and small valleys, transfer of small streams from surface into underground pipes or collectors, etc.) combined with creation of systems of concrete-protected surface drainages and underground storm flow sewages. Such activities can result in substantial changes of runoff- and sediment-contributing areas for the remaining gullies and small valleys in comparison to the pre-urbanization conditions, causing dramatic increase of fluvial activity in some of those and much lower flow discharges in others. In addition, gullies and small valleys in urban settlements often become sites of dumping for both dry and liquid domestic and industrial wastes, thus being major pathways for dissolved and particle-bound pollutant transfer into perennial streams and rivers. All the problems listed require detailed hydrological and geomorphic investigations in order to provide sound basis for developing appropriate measures aimed to control and decrease urban erosion, sediment redistribution, pollution of water bodies, damage to constructions and communications. Recent advances in sediment tracing and fingerprinting techniques provide promising opportunities

    For the seventh time since 2005, the CERN School of Computing (see here) has scheduled its inverted school for February. iCSCs are part of the CSC series of events, together with the main summer school to be held this year in Portugal and the thematic school (see here) in Split next June.   The inverted CSC, iCSC2014, will take place at CERN on 24 and 25 February, in Room 31/3-004. The inverted CSCs stem from the observation that at regular CSCs it is common to find someone in the room who knows more on a particular (usually advanced) topic than the lecturer. So why not try and exploit this and turn the students into teachers? CSC2013 students made proposals via an electronic discussion forum, from which a programme was designed. This year’s programme focuses on timely, challenging and innovative topics, including: network programming, building distributed systems, a journey from quark to jet in physics, read-out electronics: where data come from, machine learning and data mining.

  14. Mortality pattern and life expectancy of Seventh-Day Adventists in the Netherlands.

    Science.gov (United States)

    Berkel, J; de Waard, F

    1983-12-01

    The mortality pattern of Seventh-Day Adventists (SDAs) in the Netherlands was assessed during a ten-year study period, 1968-1977. Of 522 deceased SDAs the causes of death of 482 could be ascertained. Standardized Mortality Ratios (SMR) for total mortality (SMR = 0,45), cancer (SMR = 0,50) and cardiovascular diseases (SMR = 0,41) as well as for various subgroups differed significantly from the total Dutch population. Mean age at death as well as life-expectation at baptism were significantly higher in SDAs, both in males and females, as compared with Dutch males and females. A health survey among a sample of the total SDA population and a group of 'friend' controls' was done in order to try to explain the differences in mortality pattern and life expectancy. It is concluded that evidence was found for the thesis that abstinence from cigarette smoking is the main factor explaining the low mortality from ischaemic heart diseases among SDAs, while presumably an appropriate (prudent) diet confers additional benefit for example on colon cancer mortality.

  15. High-grade and low-grade gliomas: differentiation by using perfusion MR imaging

    2005-01-01

    AIM: Relative cerebral blood volume (rCBV) is a commonly used perfusion magnetic resonance imaging (MRI) technique for the evaluation of tumour grade. Relative cerebral blood flow (rCBF) has been less studied. The goal of our study was to determine the usefulness of these parameters in evaluating the histopathological grade of the cerebral gliomas. METHODS: This study involved 33 patients (22 high-grade and 11 low-grade glioma cases). MRI was performed for all tumours by using a first-passage gadopentetate dimeglumine T2*-weighted gradient-echo single-shot echo-planar sequence followed by conventional MRI. The rCBV and rCBF were calculated by deconvolution of an arterial input function. The rCBV and rCBF ratios of the lesions were obtained by dividing the values obtained from the normal white matter of the contralateral hemisphere. For statistical analysis Mann-Whitney testing was carried out. A p value of less than 0.05 indicated a statistically significant difference. Receiver operating characteristic curve (ROC) analysis was performed to assess the relationship between the rCBV and rCBF ratios and grade of gliomas. Their cut-off value permitting discrimination was calculated. The correlation between rCBV and CBF ratios and glioma grade was assessed using Pearson correlation analysis. RESULTS: In high-grade gliomas, rCBV and rCBF ratios were measured as 6.50±4.29 and 3.32±1.87 (mean±SD), respectively. In low-grade gliomas, rCBV and rCBF ratios were 1.69±0.51 and 1.16±0.38, respectively. The rCBV and rCBF ratios for high-grade gliomas were statistically different from those of low-grade gliomas (p 0.05). The cut-off value was taken as 1.98 in the rCBV ratio and 1.25 in the rCBF ratio. There was a strong correlation between the rCBV and CBF ratios (Pearson correlation = 0.830, p<0.05). CONCLUSION: Perfusion MRI is useful in the preoperative assessment of the histopathologicalal grade of gliomas; the rCBF ratio in addition to the rCBV ratio can be incorporated

  16. Hypertension, antihypertensive medication and risk of renal carcinoma in California Seventh-Day Adventists.

    Fraser, G E; Phillips, R L; Beeson, W L

    1990-12-01

    A longitudinal study of 34 198 non-Hispanic white California Seventh-day Adventists identified incident cases of renal carcinoma over six years of follow-up. The use of antihypertensive medications and self-reported hypertension had estimated age-sex adjusted incidence rate ratios of 4.51 and 2.90 respectively. These were relatively unchanged by stratifying on additional variables that may have been confounders. Cases diagnosed later during the follow-up period had the strongest association with hypertension, making the alternative explanation that the cancer may have caused the hypertension less likely. Being married in 1976 (amongst females at least) was also associated with a marked elevation of risk. Point estimates of effect suggested that frequent (greater than or equal to 3 week) consumption of fruit (RR = 0.21) and salad vegetables (RR = 0.34) may be protective for this cancer, although the 95% confidence interval did not quite exclude the null value.

    Full Text Available City planning is a complex task and through this work we face the space and natural resources that expose the exploitation (that are to be exploited and prone to unsustainable change. Often without environmental responsibility and the imperative of creating certain measures we make superstructure no matter how much the environment may be disrupted, and whether such relationships create a better society, better network of urban settlements and a better man. At that may also affect our knowledge which is often due to a variety of doctrines and legislative regulations that are applied in the planning and management space. From this it can be seen that modern architecture did not contribute to the creation of better cities. Also, urban planning is mainly restricted to the regulation and it neglected the creative action, regional-planning is lost in theoretical research, while the consideration of the whole problem is abandoned. In addition to this, in today’s transitional terms and the domineering (dominant urban crisis unsustainable combination and identification of the “2D” and the “3D” terminology is recognizable, which is only indicators that in the field of urban planning some transitional trends are prevailing. This unsustainable state of affairs in the transitional planning of urban areas can be applied in the most suitable way to pseudo-urbanization, sub-urbanization, unbalanced eco-reciprocity, non-standard construction of the urban tissue, discontinuity inherited and newly constructed urban substance. In this regard, consequently expressed negative environmental legacy of reproduction and the increased effect of the negative consequences of greenhouse gases from the threatening climate change, only shows that urban planners are not sinless and, they more or less (unconsciously complicit and participate in the contamination of urban and environment.

    Students living in urban environments may have a washed-out night sky, but their enthusiasm for astronomy can still shine bright. As an educator, it can sometimes be a challenge to see the opportunities afforded by city living to the teaching of astronomy; however, several benefits can be identified. For example, the intrinsic understanding children have of the distances and scales involved in their everyday life is enhanced when they live in a regimented urban structure. This existing understanding of scale is critical to building a foundation for later conceptualizing of the universe.Leveraging the assets of New York City and the resources found in the American Museum of Natural History, The Science and Nature Program offers students (PreK through 8th grade) robust science learning experiences. To address concepts important for studying astronomy, we present a novel twist on the classic lesson “Earth as a Peppercorn,” by scaling the solar system to the size of New York City. Using local landmarks and their distance in relation to the Museum to represent the planets, students can use their prior knowledge of their surroundings to appreciate the impressive scale of our neighborhood in space in the context of their own neighborhoods. We correlate the activity with NGSS standards, present preliminary feedback on it’s success, and discuss the opportunities to apply a similar model lesson to other astronomical systems.

    1999-01-01

    Until recently, it was thought that Kenya would be an overwhelmingly rural country and that urbanization would not be a problem, because it was associated with modernization and industrialization. Both Government of Kenya (GoK) and international donor agencies fostered rural developmental and agricultural-based strategies without paying attention to rapid rates of urbanization. Today, the high rate of urbanization in Kenya has been added to the long list of potentially devastating development problems that must be addressed. The fundamental problem is that, the urban population is growing very fast while the economic growth and development transformations necessary to support it enhance the quality of urban life are not occurring as rapidly. The new planning strategy for Kenya is to move beyond isolated projects, that emphasize shelter and residential infrastructure towards integrated urban-wide effort that promote urban productivity and reduce constraints on efficiency

  4. Sustainable Urban Biophilia: The Case of Greenskins for Urban Density

    Directory of Open Access Journals (Sweden)

    Grant Revell

    2014-08-01

    Full Text Available Green infrastructure ameliorates the urban heat island effect, contributes positively to liveability and enables sustainability in higher density urban environments. Greenskins (living architectures are a more specific form of green infrastructure, including green walls and green roofs, for dense urban areas. These offer a new approach for sustainable urban biophilia and some forms can be built using the ecological design principles of constructed wetlands. The paper compares findings from two urban centres in warm Mediterranean climates. In general from Adelaide, South Australia and more specifically from university collaborative projects on particular technical and social parameters necessary to sustain Greenskins in dense urban conditions in Fremantle, Western Australia. Results from trials of a prototype greywater Greenskin using vertical constructed wetland cells are reported. Through an experimental investigation of designing living green walls in urban Fremantle, this paper challenges the conventional “triple-bottom-line” approach to sustainable dense urban systems by addressing the greater aesthetic needs of sustainability and its thinking. Here landscape aesthetics looks to the collaborative fields of urban design, environmental engineering and landscape architecture to design new urban biophilic experiences and restorative landscapes for regenerative cultural pleasure, ecological responsibility, environmental stewardship and intellectual gain.

    2014-01-01

    Full Text Available This review paper focuses on research schemes regarding urbanity and urbanization, and brings together both cultural and physical approaches. First, we review the cultural and social construction of urbanity (as related to urbanization in Germany. In the early 20th century, urbanity was mainly the result of identity derived from a historical perspective in cities. This has changed profoundly in recent decades as urbanity stems more and more from various urban lifestyles and the staging of societal experiences, as summarized in the German term, “Erlebnisgesellschaft” (thrill-seeking society. The discussion is extended by an assessment of the recent state of the art regarding physical urban research. The focus lies on different fields of research; we address topics such as biodiversity, urban climate, air pollution, and resilience, as well as their impact on urban planning and governance. In conclusion, in order to tackle recent developments and future challenges regarding social and environmental issues, an integrative approach urges novel cross- and inter-disciplinary research efforts in urban studies, including urban-rural linkages. A newly constituted assessment of urbanization and city quarter development is proposed; the assessment focuses on the conjoint analysis of mobility, “Energiewende” (energy transition, cultural drivers, demographic development, and environmental issues.

  7. Trends in Urbanization and Implications for Peri-Urban Livelihoods in Accra, Ghana

    Science.gov (United States)

    Adom, Cynthia

    Urbanization is a common occurrence in both developed and developing worlds. Similar to occurrences in other developing world cities, Accra's urbanization is marked by fast, unplanned and uneven growth into mostly peripheral lands (Grant and Yankson 2002; Yeboah 2001; Ghana Statistical Service (GSS) 2002). Such trends in urbanization in places where data on the urbanization process is seriously inadequate and infrequent, (Rakodi 1997a; Ohadika 1991; Fasona and Omojola 2004) pose a major challenge to urban planning and management (Henderson 2002), and affect the livelihood base of several peri-urban households. Properly monitoring the urbanization process in the developing world and understanding its effects on people's lives depends on the availability of useful and up-to- date data (Weber and Puissant 2003; Mundia and Aniya 2006) that could be obtained using new and robust analytical techniques (Yang 2003). In addition, in the urban environment, differences in rates of urbanization, income, employment status, and gender dynamics across neighborhoods suggest that the impacts of increasing urbanization on peri-urban livelihoods are likely to vary across peoples and places. Against this backdrop, this dissertation uses Accra as a case study to, first, measures the nature and extent of urban expansion using a non-conventional technique, and then analyzes neighborhood - and gender-differentiated impacts of increasing urbanization on household livelihoods in peri-urban Accra. Study findings reveal: 1) major conversion of vegetated land to urban lands uses and support the effectiveness of the Self-Organizing Map and Landsat data to map complex and hazy urban tropical environments; 2) that the impacts of urbanization on peri-urban livelihoods are structured along the lines of neighborhood-level urbanization; changes brought by a higher rate of urbanization are more beneficial than harmful to household livelihoods; 3) that positive livelihood outcomes in high

The standard basic constructions and definitions like tensor products, spaces of multilinear mappings, contractions, symmetrization, symmetric algebra, as well as the transpose, adjoint, and trace of a linear mapping, are generalized to the graded case and a multitude of canonical isomorphisms is presented. Moreover, the graded versions of the classical Lie algebras are introduced and some of their basic properties are described. (orig.)

  10. Urban Modality

    2016-02-01

    Full Text Available This thesis proposes a framework for evaluating the mobility potential and performance of urban areas in the city region, as an instrument to support urban development that contributes positively to regional sustainable mobility objectives. The research takes a quantitative approach, modelling and measuring the characteristics of a city-region and of its individual urban areas, in terms of travel patterns and socioeconomic characteristics of the resident population, and in terms of built environment characteristics. It then explores how the built environment defines the affordances of urban areas for travelling by particular modes of transport, i.e. its walk-ability, cycleability, drive-ability and transit-ability, by developing a typology of what I call their ‘urban modality’. And finally the work combines this typology with the socio-economic characteristics of urban areas to determine their sustainable mobility potential and performance. It focuses on the case of the Randstad region of the Netherlands and its VINEX neighbourhoods, which are an emblematic example of new urban areas created under a policy programme with sustainable mobility objectives. A key stance in this work is the understanding that the location of an urban area in the region can be indicative of its population’s travel patterns, because the built environment (infrastructural and socio-economic characteristics are interrelated and present strong regional spatial patterns. What types of urban areas support sustainable travel patterns, and what are their spatial characteristics? How do new neighbourhoods compare to the best performing urban areas, and to other areas of the same ‘modality’ type? These are some of the questions addressed in this study. There are two main contributions of this research: the methods for building and analysing integrated multimodal network models, and the framework for contextual performance evaluation using urban area typologies.

    1985-02-01

    Associations between fatal colon or colorectal cancer and frequency of use of meat, cheese, milk, eggs, green salad, and coffee, as well as percent desirable weight, are described with the use of 21 years of follow-up for 25,493 white California Seventh-Day Adventists. Associations are presented in terms of relative risk (RR) of colorectal cancer for heavy or light exposure versus rare exposure. There were no clear relationships evident between colon or rectal cancer and meat, cheese, milk, or green salad use. Egg use was positively associated with risk of fatal colon cancer in both males (RR = 1.6) and females (RR = 1.7). Coffee use was positively associated with both colon and rectal cancer mortality in males and females, particularly for colon cancer during the last 11 years of follow-up (male RR = 3.5; female RR = 1.9). Overweight (percent of desirable weight greater than or equal to 125) was associated with an increased risk of fatal rectal cancer in both sexes combined (RR = 2.8) and colon cancer in males only (RR = 3.3). Furthermore, eggs, coffee, and overweight appear to be independently associated with risk of both colon and colorectal cancer. These three factors may explain a substantial portion of the colorectal cancer mortality differential between Adventists and U.S. whites (62% for males; 30% for females).

  12. Perceived School and Neighborhood Safety, Neighborhood Violence and Academic Achievement in Urban School Children

    2010-01-01

    Community and school violence continue to be a major public health problem, especially among urban children and adolescents. Little research has focused on the effect of school safety and neighborhood violence on academic performance. This study examines the effect of the school and neighborhood climate on academic achievement among a population of 3rd-5th grade students in an urban public school system. Community and school safety were assessed using the School Climate Survey, an annual city-wide assessment of student’s perception of school and community safety. Community violence was measured using the Neighborhood Inventory for Environmental Typology, an objective observational assessment of neighborhood characteristics. Academic achievement was measured using the Maryland State Assessment (MSA), a standardized exam given to all Maryland 3rd-8th graders. School Climate Data and MSA data were aggregated by school and grade. Objective assessments of neighborhood environment and students’ self-reported school and neighborhood safety were both strongly associated with academic performance. Increasing neighborhood violence was associated with statistically significant decreases from 4.2%-8.7% in math and reading achievement; increasing perceived safety was associated with significant increases in achievement from 16%-22%. These preliminary findings highlight the adverse impact of perceived safety and community violence exposure on primary school children’s academic performance. PMID:21197388

    Despite ample evidence for the benefits of parental autonomy support and the harms of parental psychological control to Chinese adolescents' well-being, little is known about what foreshadows these parenting behaviors among Chinese parents. The current research addressed this gap in the literature. It tested the hypothesis that parents' endorsement of self-development socialization goals (i.e., regarding a positive sense of self in terms of holding optimistic attitudes toward oneself, feeling autonomous in one's actions, and establishing one's independence from others, as important for adolescents to develop) and adolescents' school performance may interact to predict parental autonomy support and psychological control in urban China. Three hundred and forty-one Chinese seventh graders (mean age = 13.30 years, 58 % female) and their parents (186 mothers and 155 fathers) participated. Parents reported on their own and their spouses' endorsement of self-development socialization goals; adolescents reported on parental autonomy support and psychological control; and adolescents' grades were obtained from school records. Significant interactions were found between parents' socialization goals and adolescents' grades in predicting parenting behaviors. When adolescents were doing well at school, the stronger parents' endorsement of self-development socialization goals, the greater their autonomy support and the lesser their psychological control; when adolescents were doing poorly at school, regardless of parents' socialization goals, their autonomy support was relatively low and their psychological control was relatively high. These findings highlight a tension between parental concerns over adolescents' self-development and academic success, which needs to be resolved to promote autonomy support and prevent psychological control among urban Chinese parents.

    It has been suggested that both performance and academic well-being play a role in adolescent students' educational attainment and school dropout. In this study, we therefore examined, first, what kinds of academic well-being (i.e., school burnout, schoolwork engagement, and mathematics self-concept) and mathematics performance profiles can be identified among lower secondary school students ( N grade 7 = 583, N grade 9 = 497); second, how stable these profiles are across one school year during the seventh and ninth grades; and, third, how students with different academic well-being and mathematics performance profiles differ with respect to their educational aspirations. By means of latent profile analyses, three groups of students in seventh grade: thriving (34%), average (51%), and negative academic well-being (15%) and four groups of students in ninth grade: thriving (25%), average (50%), negative academic well-being (18%), and low-performing (7%) with distinct well-being and mathematics performance profiles were identified. Configural frequency analyses revealed that the profiles were relatively stable across one school year; 60% of the students displayed identical profiles over time. The thriving students reported the highest educational aspirations compared to the other groups. In addition, the low-performing students in the ninth grade had the lowest educational aspirations just before the transition to upper secondary school. Practical implications as well as directions for future research are discussed.

  20. A content analysis of sixth-grade, seventh-grade, and eighth-grade science textbooks with regard to the nature of science

    Science.gov (United States)

    Phillips, Marianne C.

    Science teachers rely heavily on their textbooks; for many, it is the only curriculum they use (Weiss, 1993). Therefore, it is important these materials convey an accurate conception of the nature of science. Science for All Americans (AAAS, 1990) and the National Science Education Standards (NRC, 1996) call for teaching students about the nature of science. Including the nature of science throughout science textbooks will produce scientifically literate citizens (Driver and others, 1993) with an improved ability to make informed decisions (McComas, 1998). Teaching the nature of science supports the successful learning of science content and process (Driver and others, 1996), and bridges the gap between the two cultures of practicing scientists and school science (Sorsby, 2000). Do middle school science textbooks provide a balanced presentation of the nature of science throughout their text? To determine the answer, this investigation used a content analysis technique to analyze a random sample from the introduction chapter and the rest of the textbook chapters from twelve middle school science textbooks for the four aspects of the nature of science (Chiappetta, Fillman, & Sethna, 2004). Scoring procedures were used to determine interrater agreement using both Cohen's kappa (kappa) and Krippendorff's alpha (alpha). Kappa values were determined to be fair to excellent beyond chance among the three coders. The resulting values for Krippendorff's alpha ranged from acceptable (alpha > .80) to unacceptable (alpha imbalance is providing students with a rudimentary and fragmented view of how science works, despite the fact that science impacts every aspect of life (McComas, 1998). Given the impact of textbooks on learning, it is recommended that teachers be informed of these shortcomings to enable them to supplement content where it is lacking.

    2010-12-01

    Urbanization is a global multidimensional process paired with increasing uncertainty due to climate change, migration of people, and changes in the capacity to sustain ecosystem services. This article lays a foundation for discussing transitions in urban governance, which enable cities to navigate change, build capacity to withstand shocks, and use experimentation and innovation in face of uncertainty. Using the three concrete case cities--New Orleans, Cape Town, and Phoenix--the article analyzes thresholds and cross-scale interactions, and expands the scale at which urban resilience has been discussed by integrating the idea from geography that cities form part of "system of cities" (i.e., they cannot be seen as single entities). Based on this, the article argues that urban governance need to harness social networks of urban innovation to sustain ecosystem services, while nurturing discourses that situate the city as part of regional ecosystems. The article broadens the discussion on urban resilience while challenging resilience theory when addressing human-dominated ecosystems. Practical examples of harnessing urban innovation are presented, paired with an agenda for research and policy.

    2016-05-01

    Full Text Available The process of urbanization in Romania was a very tumultuous and slightly different one compared to other Central and Eastern European countries, being marked by the constant willingness to increase the degree of urbanization. The communist period was the most significant from this point of view, by considering both the number of newly declared towns and urban population growth. The urbanization of communist era corroborated with the excessive and forced industrialization has generated imbalances in the urban system and created distortions in the urban hierarchy. However, the legislative inconsistency and the lack of urban regulations during the post – communist period have lead to the increasing number of new (quasi urban units (many of which without urban amenities to the chaotic sub-urbanization of cities and urban decline. In many cases, the ability of local authorities to manage the urban development in the early years of transition has been hampered by inadequate legislation that regulates the urban growth in a completely different socio-economic system. Thus, the lacks of specific urban policies and urban regeneration plans have determined indirectly a hypertrophic evolution and an uncontrolled suburban expansion. Bucharest, the capital of the country has been most affected by these processes determining multilayered space transformation within the city and open space conversion to commercial and residential use, both affecting the urban environment and quality of life of urban-rural communities. The paper focuses on the patterns, the driving forces and the consequences of two opposing processes: socialist forced urbanization vs. post-socialist chaotic urbanization unfolding across the national urban landscape.

  14. An Advanced Method to Apply Multiple Rainfall Thresholds for Urban Flood Warnings

    Jiun-Huei Jang

    2015-11-01

    Full Text Available Issuing warning information to the public when rainfall exceeds given thresholds is a simple and widely-used method to minimize flood risk; however, this method lacks sophistication when compared with hydrodynamic simulation. In this study, an advanced methodology is proposed to improve the warning effectiveness of the rainfall threshold method for urban areas through deterministic-stochastic modeling, without sacrificing simplicity and efficiency. With regards to flooding mechanisms, rainfall thresholds of different durations are divided into two groups accounting for flooding caused by drainage overload and disastrous runoff, which help in grading the warning level in terms of emergency and severity when the two are observed together. A flood warning is then classified into four levels distinguished by green, yellow, orange, and red lights in ascending order of priority that indicate the required measures, from standby, flood defense, evacuation to rescue, respectively. The proposed methodology is tested according to 22 historical events in the last 10 years for 252 urbanized townships in Taiwan. The results show satisfactory accuracy in predicting the occurrence and timing of flooding, with a logical warning time series for taking progressive measures. For systems with multiple rainfall thresholds already in place, the methodology can be used to ensure better application of rainfall thresholds in urban flood warnings.

    A student-centered innovative method of teaching veterinary parasitology was launched and evaluated at the Ross University School of Veterinary Medicine (RUSVM) in St. Kitts, where Parasitology is a required course for second-semester veterinary students. A novel method, named Iron Parasitology, compared lecturer-centered teaching with student-centered teaching and assessed the retention of parasitology knowledge of students in their second semester and again when they reached their seventh semester. Members of five consecutive classes chose to participate in Iron Parasitology with the opportunity to earn an additional 10 points toward their final grade by demonstrating their knowledge, communication skills, clarity of message, and creativity in the Iron Parasitology exercise. The participants and nonparticipants were assessed using seven parameters. The initial short-term study parameters used to evaluate lecturer- versus student-centered teaching were age, gender, final Parasitology course grade without Iron Parasitology, RUSVM overall grade point average (GPA), RUSVM second-semester GPA, overall GPA before RUSVM, and prerequisite GPA before RUSVM. The long-term reassessment study assessed retention of parasitology knowledge in members of the seventh-semester class who had Iron Parasitology as a tool in their second semester. These students were invited to complete a parasitology final examination during their seventh semester. There were no statistically significant differences for the parameters measured in the initial study. In addition, Iron Parasitology did not have an effect on the retention scores in the reassessment study.

    Genetic toxicology and its role in the detection of carcinogens is currently undergoing a period of reappraisal. There is an increasing interest in developing alternatives to animal testing and the three R's of reduction, refinement and replacement are the basis for EU and national animal protection laws the Seventh Amendment to the EU Cosmetics Directive will ban the marketing of cosmetic/personal care products that contain ingredients that have been tested in animal models. Thus in vivo tests such as the bone marrow micronucleus test, which has a key role in current testing strategies for genotoxicity, will not be available for this class of products. The attrition rate for new, valuable and safe chemicals tested in an in vitro-only testing battery, using the in vitro tests currently established for genotoxicity screening, will greatly increase once this legislation is in place. In addition there has been an explosion of knowledge concerning the cellular and molecular events leading to carcinogenesis. This knowledge has not yet been fully factored into screening chemicals for properties that are not directly linked to mutation induction. Thus there is a pressing need for new, more accurate approaches to determine genotoxicity and carcinogenicity. However, a considerable challenge is presented for these new approaches to be universally accepted and new tests sufficiently validated by March 2009 when the animal testing and marketing bans associated with the Seventh Amendment are due to come into force. This commentary brings together ideas and approaches from several international workshops and meetings to consider these issues.
