    To outline the prevalence and disparities of teen pregnancy among school-aged urban minority youth, causal pathways through which nonmarital teen births adversely affects academic achievement, and proven or promising approaches for schools to address this problem. Literature review. In 2006, the birth rate among 15- to 17-year-old non-Hispanic Blacks (36.1 per 1000) was more than three times as high, and the birth rate among Hispanics (47.9 per 1000) was more than four times as high as the birth rate among non-Hispanic Whites (11.8 per 1000). Compared with women who delay childbearing until age 30, teen mothers' education is estimated to be approximately 2 years shorter. Teen mothers are 10-12% less likely to complete high school and have 14-29% lower odds of attending college. School-based programs have the potential to help teens acquire the knowledge and skills needed to postpone sex, practice safer sex, avoid unintended pregnancy, and if pregnant, to complete high school and pursue postsecondary education. Most students in US middle and high schools receive some kind of sex education. Federal policies and legislation have increased use of the abstinence-only-until-marriage approach, which is disappointing considering the lack of evidence that this approach is effective. Nonmarital teen births are highly and disproportionately prevalent among school-aged urban minority youth, have a negative impact on educational attainment, and effective practices are available for schools to address this problem. Teen pregnancy exerts an important influence on educational attainment among urban minority youth. Decisions about what will be taught should be informed by empirical data documenting the effectiveness of alternative approaches. © 2011, American School Health Association.

    2016-01-01

    Chronic pain is a significant problem in children and teens, and adolescents with chronic pain often struggle to attend school on a regular basis. We present in this article a novel program we developed that integrates attendance at a group cognitive-behavioural chronic pain self-management program with earning high school credits. We collaborated with Alberta Education in the development of this course, Chronic Pain 35. Adolescents who choose to enroll are invited to demonstrate their scientific knowledge related to pain, understanding of and engagement with treatment homework, and demonstrate their creativity by completing a project, which demonstrates at least one concept. Integrating Chronic Pain 35 into an adolescent’s academic achievements is a creative strategy that facilitates the engagement of adolescents in learning and adopting pain coping techniques. It also helps teens to advocate for themselves in the school environment and improve their parents’ and teachers’ understanding of adolescent chronic pain. This is one of the first successful collaborations between a pediatric health program and provincial education leaders, aimed at integrating learning and obtaining school credit for learning about and engaging in health self-management for teens. The authors hope this paper serves as an effective reference model for any future collaborating programs aimed at supporting teens with chronic pain to obtain high school credits. PMID:27869766

    2017-10-01

    Teen dating violence (TDV), bullying, and HIV risk behaviors are public health concerns that impact adolescents in the United States. National estimates reveal high rates of these risk behaviors among high school students. Based on theoretical and empirical evidence, we hypothesized that experiencing teen dating violence (sexual and physical) would mediate the impact of bullying on HIV risk. Data were from the 2013 National Youth Behavior Risk Surveillance Survey (YRBSS) among students who answered questions on bullying, TDV, and HIV risk (N = 13,571). The YRBSS is conducted biennially among 9th- to 12th-grade students nationally. We used multiple regression analysis and Hayes' SPSS process macro to examine the 2 study hypotheses. Findings from bivariate analysis suggest an association between bullying and HIV risk. The study also found associations between physical, sexual teen dating violence and HIV risk. Results also indicate that both physical and sexual teen dating violence mediate the association between bullying and HIV risk. Our findings suggest that multidimensional interventions should be developed to reduce the rate of teen dating violence and combat bullying as a preventative method for HIV risk among high school students. © 2017, American School Health Association.

    A content analysis of the MTV shows 16 and Pregnant (n = 59), Teen Mom (n = 20), and Teen Mom 2 (n = 20) was conducted to determine whether these programs accurately portray teen pregnancy. The results revealed that teen mothers on 16 and Pregnant were younger, more often White, and had more healthy babies as compared to national averages. The babies' fathers were more involved in the daily care of their child as compared to reality. Medical insurance or receipt of government assistance was almost never discussed. Teen mothers in the Teen Mom shows were significantly more likely to achieve a high school diploma as compared to reality. Finally, mothers on Teen Mom and Teen Mom 2 were significantly less likely to voice concern about finances and had more active social lives than mothers on 16 and Pregnant. Using social learning theory as a theoretical framework, we argue that these shows provide mixed messages to young audiences about teen pregnancy and parenthood.

  19. Why is the teen birth rate in the United States so high and why does it matter?

    Science.gov (United States)

    Kearney, Melissa S; Levine, Phillip B

    2012-01-01

    Teens in the United States are far more likely to give birth than in any other industrialized country in the world. U.S. teens are two and a half times as likely to give birth as compared to teens in Canada, around four times as likely as teens in Germany or Norway, and almost 10 times as likely as teens in Switzerland. Among more developed countries, Russia has the next highest teen birth rate after the United States, but an American teenage girl is still around 25 percent more likely to give birth than her counterpart in Russia. Moreover, these statistics incorporate the almost 40 percent fall in the teen birth rate that the United States has experienced over the past two decades. Differences across U.S. states are quite dramatic as well. A teenage girl in Mississippi is four times more likely to give birth than a teenage girl in New Hampshire--and 15 times more likely to give birth as a teen compared to a teenage girl in Switzerland. This paper has two overarching goals: understanding why the teen birth rate is so high in the United States and understanding why it matters. Thus, we begin by examining multiple sources of data to put current rates of teen childbearing into the perspective of cross-country comparisons and recent historical context. We examine teen birth rates alongside pregnancy, abortion, and "shotgun" marriage rates as well as the antecedent behaviors of sexual activity and contraceptive use. We seek insights as to why the rate of teen childbearing is so unusually high in the United States as a whole, and in some U.S. states in particular. We argue that explanations that economists have tended to study are unable to account for any sizable share of the variation in teen childbearing rates across place. We describe some recent empirical work demonstrating that variation in income inequality across U.S. states and developed countries can explain a sizable share of the geographic variation in teen childbearing. To the extent that income inequality

    Unexpected increases in the teen birth rates have stimulated a renewed focus on the prevention of teen pregnancy. Although many adults believe there are certain costs associated with teen parenting, the attitudes of teens toward the parenting experience are not known. The purpose of this descriptive study was to determine teens' thoughts on how their lives would change if they experienced a teen birth in the areas of relationships, vocation, and life impacts. The Thoughts on Teen Parenting Survey (TTPS), designed to measure demographic variables and perspectives on the costs and rewards of teen parenting, was administered to 695 high school students. The survey yielded a composite score, subscale scores, and aggregate data measuring teen thoughts on the consequences of the teen parenting experience. Findings may be used to identify teens at risk for pregnancy, develop interventions, and evaluate prevention strategies based on the insights of teens.

    Full Text Available Background: Teen pregnancy and abortion phenomena take an ever-growing magnitude in poor countries. Lack of knowledge about reproductive health could aggravate these problems. Methods: Across-sectional survey has been conducted in public, private and denominational high schools of the urban district of Antananarivo, Madagascar, on a sample of 248 students during schoolyear 2012-2013. Data was collected during the third quarter of the schoolyear. Results: Good knowledge about pregnancy and abortion was found in 14.5%, 95% CI [10.4% -19.5%] of students. The media represent almost 60% of the sources of information. Access to care is limited in 48% of cases by feeling shame. Nearly 11% would resort to abortion if an unplanned pregnancy happens. Nearly 6.5%, 95% CI [3.6% - 10.3%] had teen pregnancy problems: 9.6% of boys and 4.1% of girls came encountered these and all cases have ended in induced abortion among girls. The students from the denominational schools and the female gender have more knowledge of about sexuality. The level of knowledge does not significantly influence pregnancy. Female students (p = 0.07 are less prone to teen pregnancy, whereas dating a fixed boyfriend (p <10-4, a large sibship (p = 0.03 and parents in consensual union (p = 0.02 encourage its occurrence. Conclusions: Abortion does not actually represent a remedy in case of pregnancy. Nevertheless, prevention of teen pregnancy is suggested. The control strategy should be multidisciplinary and multisectoral, and focused on targeted information. [TAF Prev Med Bull 2015; 14(3.000: 240-246

    To assess the associations between vascular and metabolic comorbidities and the prevalence of open-angle glaucoma (OAG) with low-teen and high-teen intraocular pressure (IOP) in Korea. Cross-sectional data from the Korean National Health and Nutrition Examination Survey from 2008 to 2012 were analysed. Participants diagnosed with OAG with normal IOP were further classified into low-teen IOP (IOP ≤ 15 mmHg) and high-teen IOP (15 mmHg teen IOP groups. The prevalences of hypertension, hyperlipidemia, ischaemic heart disease, stroke and metabolic syndrome were significantly higher among subjects with low-teen OAG compared with normal subjects, while only the prevalences of hypertension and stroke were higher among subjects with high-teen OAG compared with normal subjects. In multivariate logistic regression models adjusted for confounding factors, low-teen OAG was significantly associated with hypertension (OR, 1.68; 95% CI, 1.30-2.18), hyperlipidemia (OR, 1.49; 95% CI, 1.07-2.08), ischaemic heart disease (OR, 1.83; 95% CI, 1.07-3.11), stroke (OR, 1.91; 95% CI, 1.12-3.25) and metabolic syndrome (OR, 1.46; 95% CI, 1.12-1.90). High-teen OAG was only associated with stroke (OR, 2.58; 95% CI, 1.20-5.53). Various vascular and metabolic comorbidities were significantly associated with low-teen OAG, but not with high-teen OAG. These data support the hypothesis that vascular factors play a more significant role in the pathogenesis of OAG with low-teen baseline IOP. © 2017 Acta Ophthalmologica Scandinavica Foundation.

    After years of high teen birth rates, there is currently a decline in U.S. pregnancy and birth rates among teens. Nevertheless, these rates continue to be higher than those of most global counterparts, and psychosocial and physical adversities still occur for pregnant teens and their children. The declining birth rates may be due to teens making better choices about contraceptive use and sexual behaviors. Psychiatric-mental health nurses are in key positions to enhance pregnancy prevention for teens. [Journal of Psychosocial Nursing and Mental Health Services, 54(2), 25-28.].

    Overall, children born to teen parents experience disadvantaged cognitive achievement at school entry compared to children born to older parents. However, within this population there is variation, with a significant fraction of teen parents’ children acquiring adequate preparation for school entry during early childhood. We ask whether the family background of teen parents explains this variation. We use data on children born to teen mothers from three waves of the Early Childhood Longitudinal Study-Birth Cohort (N~700) to study the association of family background with children's standardized reading and mathematics achievement scores at kindergarten entry. When neither maternal grandparent has completed high school, children's scores on standardized assessments of math and reading achievement are one-quarter to one-third of a standard deviation lower compared to families where at least one grandparent finished high school. This association is net of teen mothers’ own socioeconomic status in the year prior to children's school entry. PMID:26806989

    SmithBattle, Lee; Freed, Patricia

    2016-01-01

    Psychological distress is common in teen mothers. High rates of distress are attributed to teen mothers' childhood adversities and the challenges of parenting in the context of chronic stress, cumulative disadvantage, and limited social support. We describe the prevalence of psychological distress in teen mothers; what is known about its origins and impact on mothers and children; factors that promote teen mothers' mental health and resilience; and the many barriers that make it difficult to obtain traditional mental healthcare. We also briefly review the few studies that test interventions to improve teen mothers' mental health. Because barriers to traditional mental health treatment are ubiquitous and difficult to remedy, the second article in this two-part series calls for nurses in healthcare settings, schools, and home visiting programs to screen pregnant and parenting teens for adverse childhood experiences and psychological distress, and to integrate strength-based and trauma-based principles into their practice. Creating a supportive setting where past traumas and psychological distress are addressed with skill and sensitivity builds upon teen mothers' strengths and their aspirations to be the best parents they can be. These approaches facilitate the long-term health and development of mother and child.

    To examine pre-licensure agreement on driving expectations and predictors of teen driving expectations among parent-teen dyads. Cross-sectional survey of 163 parent-teen dyads. Descriptive statistics, weighted Kappa coefficients, and linear regression were used to examine expectations about post-licensure teen driving. Teens reported high pre-licensure unsupervised driving (N = 79, 48.5%) and regular access to a car (N = 130, 81.8%). Parents and teens had low agreement on teen driving expectations (eg, after dark, κw = 0.23). Each time teens currently drove to/from school, their expectation of driving in risky conditions post-licensure increased (β = 0.21, p = .02). Pre-licensure improvement of parent-teen agreement on driving expectations are needed to have the greatest impact on preventing teens from driving in high risk conditions.

  13. A cross-country comparison of math achievement at teen age and cognitive performance 40 years later

    Directory of Open Access Journals (Sweden)

    Vegard Skirbekk

    2014-07-01

    Full Text Available Background: Maintaining cognitive functioning through mid- to late-life is relevant for the individual and societal aim of active ageing. Evidence shows considerable stability in individual-level rank-ordering of cognitive functioning, but little attention has been given to cohort performance over the life cycle and macro-level factors that could affect it. Objective: The main goal of this paper is to address cross-national variation in mental performance from younger to older ages. Methods: Using a quasi-longitudinal approach, we compare the relative country ranking in standardised mathematical test scores at teen age in 1964 from the First International Mathematics Study (FIMS and cognitive test performance at mid-life in 2004, based on the Survey of Health, Ageing and Retirement in Europe (SHARE for the cohort born between 1949 and 1952. Results: Our results show that those countries which had the highest scores in math tests taken by 13 years old grade level students are not the same countries that, 40 years later, have the top performing scores in cognitive tests among mid-age adults. Conclusions: This article highlights the importance of considering country-level influences on cognitive change over the life cycle, in addition to individual characteristics, and provides some descriptive findings that could be incorporated with further research on the link between specific contextual factors and cognitive functioning.

    Recently, metal halide perovskite based solar cell with the characteristics of rather low raw materials cost, great potential for simple process and scalable production, and extreme high power conversion efficiency (PCE), have been highlighted as one of the most competitive technologies for next generation thin film photovoltaic (PV). In UCLA, we have realized an efficient pathway to achieve high performance pervoskite solar cells, where the findings are beneficial to this unique materials/devices system. Our recent progress lies in perovskite film formation, defect passivation, transport materials design, interface engineering with respect to high performance solar cell, as well as the exploration of its applications beyond photovoltaics. These achievements include: 1) development of vapor assisted solution process (VASP) and moisture assisted solution process, which produces perovskite film with improved conformity, high crystallinity, reduced recombination rate, and the resulting high performance; 2) examination of the defects property of perovskite materials, and demonstration of a self-induced passivation approach to reduce carrier recombination; 3) interface engineering based on design of the carrier transport materials and the electrodes, in combination with high quality perovskite film, which delivers 15 ~ 20% PCEs; 4) a novel integration of bulk heterojunction to perovskite solar cell to achieve better light harvest; 5) fabrication of inverted solar cell device with high efficiency and flexibility and 6) exploration the application of perovskite materials to photodetector. Further development in film, device architecture, and interfaces will lead to continuous improved perovskite solar cells and other organic-inorganic hybrid optoelectronics.

    Identifying the types of mathematics content knowledge that are most predictive of students' long-term learning is essential for improving both theories of mathematical development and mathematics education. To identify these types of knowledge, we examined long-term predictors of high school students' knowledge of algebra and overall mathematics achievement. Analyses of large, nationally representative, longitudinal data sets from the United States and the United Kingdom revealed that elementary school students' knowledge of fractions and of division uniquely predicts those students' knowledge of algebra and overall mathematics achievement in high school, 5 or 6 years later, even after statistically controlling for other types of mathematical knowledge, general intellectual ability, working memory, and family income and education. Implications of these findings for understanding and improving mathematics learning are discussed.

  7. Achieving high performance on the Intel Paragon

    1993-11-01

    When presented with a new supercomputer most users will first ask {open_quotes}How much faster will my applications run?{close_quotes} and then add a fearful {open_quotes}How much effort will it take me to convert to the new machine?{close_quotes} This paper describes some lessons learned at Sandia while asking these questions about the new 1800+ node Intel Paragon. The authors conclude that the operating system is crucial to both achieving high performance and allowing easy conversion from previous parallel implementations to a new machine. Using the Sandia/UNM Operating System (SUNMOS) they were able to port a LU factorization of dense matrices from the nCUBE2 to the Paragon and achieve 92% scaled speed-up on 1024 nodes. Thus on a 44,000 by 44,000 matrix which had required over 10 hours on the previous machine, they completed in less than 1/2 hour at a rate of over 40 GFLOPS. Two keys to achieving such high performance were the small size of SUNMOS (less than 256 kbytes) and the ability to send large messages with very low overhead.

    2008-04-01

    While childhood agricultural injury has long been recognized as an important public health issue, most research has focused on family farms and there have not been many interventions targeting hired youth. This study evaluated the impact of a high school English as a Second Language (ESL) curriculum, designed to provide teen agricultural workers with the knowledge and tools to protect their health and safety in the fields. Using a quasi-experimental design, the research consisted of two intervention groups and a comparison group, and included over 2,000 students from communities that lead California in agricultural production. The research findings revealed that the curriculum had significant impact in terms of increases in knowledge and attitudes, and nearly half of those interviewed after a summer of working in the fields reported implementing new behaviors to protect their health and safety. The curriculum also had extended effects in the broader community, as the majority of students reported sharing the new information with others. The study found that a school-based ESL curriculum is an effective intervention to reach and educate teen farm workers and that ESL classes can serve as a much-needed access point for young farm workers.

  11. Prepregnancy contraceptive use among teens with unintended pregnancies resulting in live births - Pregnancy Risk Assessment Monitoring System (PRAMS), 2004-2008.

    Science.gov (United States)

    2012-01-20

    Approximately 400,000 teens aged 15-19 years give birth every year in the United States (1), and the teen birth rate remains the highest in the developed world. Teen childbearing is a public health concern because teen mothers are more likely to experience negative social outcomes, including school dropout. In addition, infants of teen mothers are more likely to be low birth weight and have lower academic achievement, and daughters of teen mothers are more likely to become teen mothers themselves. To learn why teens wishing to avoid pregnancy become pregnant, CDC analyzed data from the 2004-2008 Pregnancy Risk Assessment Monitoring System (PRAMS). This report describes estimated rates of self-reported prepregnancy contraceptive use among white, black, and Hispanic teen females aged 15-19 years with unintended pregnancies resulting in live births. Approximately one half (50.1%) of these teens were not using any method of birth control when they got pregnant, and of these, nearly one third (31.4%) believed they could not get pregnant at the time; 21.0% used a highly effective contraceptive method (although less than 1% used one of the most effective methods, such as an intrauterine device [IUD]); 24.2% used the moderately effective method of condoms; and 5.1% used the least effective methods, such as rhythm and withdrawal. To decrease teen birth rates, efforts are needed to reduce or delay the onset of sexual activity, provide factual information about the conditions under which pregnancy can occur, increase teens' motivation and negotiation skills for pregnancy prevention, improve access to contraceptives, and encourage use of more effective contraceptive methods.

    2016-12-01

    Parents play a critical role in preventing crashes among teens. Research of parental perceptions and concerns regarding teen driving safety is limited. We examined results from the 2013 Summer ConsumerStyles survey that queried parents about restrictions placed on their teen drivers, their perceived level of "worry" about their teen driver's safety, and influence of parental restrictions regarding their teen's driving. We produced frequency distributions for the number of restrictions imposed, parental "worry," and influence of rules regarding their teen's driving, reported by teen's driving license status (learning to drive or obtained a driver's license). Response categories were dichotomized because of small cell sizes, and we ran separate log-linear regression models to explore whether imposing all four restrictions on teen drivers was associated with either worry intensity ("a lot" versus "somewhat, not very much or not at all") or perceived influence of parental rules ("a lot" versus "somewhat, not very much or not at all"). Among the 456 parent respondents, 80% reported having restrictions for their teen driver regarding use of safety belts, drinking and driving, cell phones, and text messaging while driving. However, among the 188 parents of licensed teens, only 9% reported having a written parent-teen driving agreement, either currently or in the past. Worrying "a lot" was reported less frequently by parents of newly licensed teens (36%) compared with parents of learning teens (61%). Parents report having rules and restrictions for their teen drivers, but only a small percentage formalize the rules and restrictions in a written parent-teen driving agreement. Parents worry less about their teen driver's safety during the newly licensed phase, when crash risk is high as compared to the learning phase. Further research is needed into how to effectively support parents in supervising and monitoring their teen driver. Published by Elsevier Ltd.

    Full Text Available We used an achievement goal framework to study the role of motivation in the academic context of a Peruvian sample of 8th to 10th grade high school students (N = 1505. The purpose of this cross-sectional study was to examine the relationship between students' achievement goals, their use of learning strategies and their academic achievement. Multiple Hierarchical Regressions Analyses identified, as predicted, positive effects of mastery goals, including more use of learning strategies and higher academic achievement, and negative effects of performance avoidance goals, including lower academic achievement. Mixed results were found for pursuing performance approach goals, which predicted a greater use of learning strategies, but were unrelated to academic achievement. The present findings support the external validity of achievement goal theory in a sample of students from a culture that is understudied in the achievement goal literature in particular and the motivational literature in general.

    McCracken, Katherine A; Loveless, Meredith

    2014-10-01

    To provide clinicians with a review of recent research and clinically applicable tools regarding teen pregnancy. Teen pregnancy rates have declined but still remain a significant problem in the USA. Teen pregnancy prevention was identified by Centers for Disease Control and Prevention as one of its top six priorities, which is increasing research and intervention data. Long-acting contraceptive methods are acceptable to teens and have been shown to reduce teen birth rates. Pregnant teens need special attention to counseling on pregnancy options and reducing risk during pregnancy with regular prenatal care. Postpartum teens should be encouraged and supported to breastfeed, monitored for depression, and have access to reliable contraception to avoid repeat undesired pregnancy. This review highlights important issues for all providers caring for female adolescents and those who may encounter teen pregnancy. Foremost prevention of teen pregnancy by comprehensive sexual education and access to contraception is the priority. Educating patients and healthcare providers about safety and efficacy of long-acting reversible contraception is a good step to reducing undesired teen pregnancies. Rates of postpartum depression are greater in adolescents than in adults, and adolescent mothers need to be screened and monitored for depression. Strategies to avoid another undesired pregnancy shortly after delivery should be implemented.

    2013-09-01

    To prepare future nurses who can deliver high quality nursing care to teen mothers, a better understanding of the nursing students' perception of teen mothers is needed. A descriptive cross-sectional study was conducted among 228 nursing students to evaluate the psychometric properties of the Positivity Toward Teen Mothers (PTTM) scale, to explore nursing students' general empathy and attitudes toward teen mothers, and to investigate the predictors of nursing students' attitudes toward teen mothers. Principal component factor analysis with varimax rotation resulted in a 19-item PTTM-Revised scale with Non-judgmental and Supportive subscales. Cronbach's alphas for the subscales were 0.84 and 0.69, respectively, and 0.87 for the total scale. Simultaneous multiple regression models showed that general empathy and having a teen mother in the family or as an acquaintance were significant predictors of positive attitudes toward teen mothers, whereas age was a significant negative predictor. The PTTM-Revised scale is a promising instrument for assessing attitudes toward teen mothers. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Chow, Jean

    2004-10-01

    The mass media has an enormous influence on adolescent women and their perceptions about the world and themselves. Teen magazines are a favoured form of the mass media, thus they were chosen for this research project. The aim of this paper is to report a study exploring the messages of health and health-related material in teen magazines from the perspective of adolescents. Knowledge of how adolescents perceive teen magazine messages can be used in the care of this client group. Interpretive inquiry, a substantively driven research approach, was used for the project. A convenience sample of 12 adolescents, aged 12-18 years, participated in two focus groups, and selected images and texts from popular North American teen magazines (YM, Teen, and Seventeen) to discuss. Focus group discussions were audiotaped and then transcribed. Individual interviews with the adolescents were also completed to obtain additional data. Audiotaped interviews were analysed using Gadamer's hermeneutic ideas about 'claim' or 'address'. The findings indicate that teen magazines promote particular expectations about health and health-related activities. Participants noted that the magazines promote the message of perfection by portraying models with perfect eyes, teeth and bodies. The magazines provide ideals of thinness which are presented in a seemingly attainable fashion. Participants stated that magazines suggest that adolescent women need male attention for protection and companionship, in order to achieve fulfillment. Being healthy or whole seemed to be dependent on the adolescent reader embracing and becoming the ideals portrayed in teen magazines. In order to provide relevant and sensitive health care, health care providers need to be cognizant of the persistent demands placed on adolescents by teen magazines and the mass media in general. Media messages and their influences need to be discussed with adolescents, either in school health programmes or clinician visits.

    Addressing the social determinants of health (SDOH) that influence teen pregnancy is paramount to eliminating disparities and achieving health equity. Expanding prevention efforts from purely individual behavior change to improving the social, political, economic, and built environments in which people live, learn, work, and play may better equip vulnerable youth to adopt and sustain healthy decisions. In 2010, the Centers for Disease Control and Prevention in partnership with the Office of Adolescent Health funded state- and community-based organizations to develop and implement the Teen Pregnancy Prevention Community-Wide Initiative. This effort approached teen pregnancy from an SDOH perspective, by identifying contextual factors that influence teen pregnancy and other adverse sexual health outcomes among vulnerable youth. Strategies included, but were not limited to, conducting a root cause analysis and establishing nontraditional partnerships to address determinants identified by community members. This article describes the value of an SDOH approach for achieving health equity, explains the integration of such an approach into community-level teen pregnancy prevention activities, and highlights two project partners' efforts to establish and nurture nontraditional partnerships to address specific SDOH.

    2013-12-01

    The 'Teen Cafè' phenomenon grew out of an NSF-funded experiment to bring the Cafè Scientifique model for engagement of the public with science and scientists to high school teenagers. Cafè Scientifique New Mexico (cafènm.org), now in its seventh year, has proven highly popular with high school teens for much the same reason as for adult Cafè programs: the blend of socializing in an attractive venue and interaction with a scientist on an interesting science topic. Teen Cafés also include exploration of the topic with hands-on activities. The success of the model has led to the creation of the national Teen Science Cafè Network (teensciencecafe.org. This first year of the new program, four 'Founding Members' of the Network-- in Florida, Colorado, North Carolina, and the St. Louis, Missouri region--started up Teen Cafè programs. Each applied the model with a unique flair appropriate to local institutions and demographics. Each Member in the Network runs Cafès in multiple local venues. We are now gearing up for our second year, and the Network is growing. Our Teen Cafè topics have covered a very wide range, from belly-button biodiversity to cyber-security to patterns of mega-earthquakes to a day in the life of a teen dolphin to corals on acid to emergency room medicine to alternative fuel cars. Presenters have come from a great variety of local institutions. Though they are popular with teens because they are fun and interesting, our evaluations have demonstrated that the programs are having a significant impact on participating teens' understanding of the nature of science, the work that scientists do, and the importance of science to their daily lives. We are also having success in training scientists to communicate effectively with this public audience. Presenters report strong satisfaction with their resulting quality of science communication. A surprising number have reported that their experience with the program has led them to think in a new way about

    1994-01-01

    The findings of an April 1994 national telephone survey of 503 high school students (252 males and 251 females) conducted by Roper Starch Worldwide were summarized. Although only 12% felt pressure to have sex with their peers and 78% reported having sex because they wanted to, over 50% of sexually active respondents also reported wishing they had waited. 62% of girls and 48% of boys wished they had waited until they were older before having their first sexual intercourse. Over 33% of respondents reported sexual activity. 25% had had oral sex and 4% had experienced anal sex. Only 8% reported no sexual experience whatsoever. More than 75% reported sexual activities such as deep kissing and petting. 75% indicated use of birth control always or most of the time. 80% used condoms all or most of the time. 57% used condoms to prevent AIDS or sexually transmitted diseases. 59% always used condoms to prevent AIDS or sexually transmitted diseases. 59% always used birth control. Those sexually active and not always using birth control indicated that the reason was unavailability of contraceptives at the time. 66% supported condom distribution in the schools. Age at first intercourse among sexually active youth averaged just under 15 years. 40% had their first experience at 14 years of age or younger. 2.7% was the average number of sexual partners among all sexually active youth. 21% had had 4 or more partners. 9 out of 10 adolescents with sexual experience found that sex was pleasurable. 81% of boys and 59% of girls agreed that sex was a pleasurable experience. 75% agreed to feeling good about sex education classes. 58% had classes in junior high school; 56% reported high school classes. Only 5% had sex education every year in school. The focus of most programs was on AIDS, abstinence, and contraception. 68% of girls and only 48% of boys felt comfortable talking with their parents about sex. 71% of girls and 45% of boys agreed that their last sexual experience was related to

    Full Text Available Background: Teen and young adult mothers have lower socioeconomic status than older mothers. Objective: This study analyzes the socioeconomic status (SES of teen, young adult, and older adult mothers across four five-year birth cohorts from 1956 to 1975 who were teens from 1971 to 1994. Methods: Data were pooled from the 1995, 2002, and 2006-2010 National Survey of Family Growth (NSFG. Mothers were categorized by age at first birth and by their birth cohorts. The SES (education, single motherhood, poverty, employment of teen, young adult, and older mothers was compared across cohorts and within cohorts. Results: Among teen mothers, the odds of fulltime employment improved across birth cohorts and the odds of educational attainment beyond high school did not vary. Their odds of single motherhood and living in poverty increased across cohorts. The odds of higher education and single motherhood increased across birth cohorts for young adult mothers as did the odds of living in poverty, even if working fulltime. Among older adult mothers, educational attainment and the odds of single motherhood rose for recent cohorts. Conclusions: Comparisons between teen mothers and both young adult and all adult mothers within cohorts suggest that gaps in single motherhood and poverty between teen and adult mothers have widened over time, to the detriment of teen mothers. Teen mothers have become more likely to be single and poor than in the past and compared to older mothers.

    Crashes are the leading cause of death for teens, and parent-based interventions are a promising approach. We assess the effectiveness of Steering Teens Safe, a parent-focused program to increase safe teen driving. Steering Teens Safe aimed to improve parental communication with teens about safe driving using motivational interviewing techniques in conjunction with 19 safe driving lessons. A randomized controlled trial involved 145 parent-teen dyads (70 intervention and 75 control). Intervention parents received a 45-minute session to learn the program with four follow-up phone sessions, a DVD, and a workbook. Control parents received a standard brochure about safe driving. Scores were developed to measure teen-reported quantity and quality of parental communication about safe driving. The main outcome measure was a previously validated Risky Driving Score reported by teens. Because the Score was highly skewed, a generalized linear model based on a gamma distribution was used for analysis. Intervention teens ranked their parent's success in talking about driving safety higher than control teens (p = 0.035) and reported that their parents talked about more topics (non-significant difference). The Risky Driving Score was 21% lower in intervention compared to control teens (85% CI = 0.60, 1.00). Interaction between communication quantity and the intervention was examined. Intervention teens who reported more successful communication had a 42% lower Risky Driving Score (95% CI = 0.37, 0.94) than control parents with less successful communication. This program had a positive although not strong effect, and it may hold the most promise in partnership with other programs, such as Driver's Education or Graduated Driver's License policies.

    Full Text Available This research has been investigating one of the most contemporary approaches of achievement motivation - Achievement Goal Theory, which uses the construct of achievement goals. The construct of achievement goals involves three types of achievement goals: mastery goals, performance approach goals and performance avoidance goals. The main goal of the research was to examine correlation between perfectionism and its aspects with particular types of achievement goals. Also, the goal was to investigate the difference concerning gender regarding the achievement goals. The sample consisted of 200 senior year high school participants. The following instruments were used: Multi-dimensional scale of perfectionism (MSP and Test of achievement goals (TCP. The research results indicate that there is significant positive correlation between: perfectionism with performance approach goals and performance avoidance goals, concern over mistakes and parental expectations with performance approach goals and performance avoidance goals, personal standards and organization with mastery goals and performance approach goals, parental criticism and doubts about action with performance avoidance goals. Significant negative correlation was found between parental criticism and mastery goals. The results concerning the second goal indicates the female subjects have higher average scores in mastery goals.

    2008-01-01

    To investigate teens' perceptions of the costs and rewards of teen births, potential interventions to prevent teen pregnancy, and the presence of someone with whom teens could discuss sexuality. Seventeen focus groups were conducted to solicit individual views, group interactions, and shared meanings. Purposive methods accessed a sample of teens considered at risk of teen pregnancy based on their membership in selected community service and teen groups. Teen parents and nonparents (n = 120), from 12 to 19 years of age, were asked about their lives and stresses and the costs and rewards related to teen births. This study yielded rich data about the consequences of teen births. Data were organized in the domains of Impact on relationships, Impact on vocation, and Impact on self. The data reflected the cost and reward themes in each domain. Though teens believed that there were positives of teen births, early childbearing was considered "hard" in many aspects. These perceptions may be used to guide programs, policies, messages, and curricula with the intent to prevent teen pregnancy. These initiatives may be more effective if informed by teens and guided by their perceptions.

    2010-01-01

    We examined medical, educational and social risks to children of teen mothers and children of nonadolescent mothers with a history of teen birth (prior teen mothers) and considered these risks at both the individual and societal level. A population-based, retrospective cohort study tracked outcomes through young adulthood for children born in Manitoba, Canada (n = 32 179). chi(2) and logistic regression analyses examined risk of childhood death or hospitalization, failure to graduate high school, intervention by child protective services, becoming a teen mother, and welfare receipt as a young adult. For children of both teen and prior teen mothers, adjusted likelihoods of death during infancy, school-aged years, and adolescence were more than 2-fold higher than for other children. Risks for hospitalization, high hospital use, academic failure, and poor social outcomes were also substantially higher. At a societal level, only 16.5% of cohort children were born to teen and prior teen mothers. However, these children accounted for 27% of first-year hospitalizations, 34% of deaths (birth to 17 years), 30% of failures to graduate high school, 51% in foster care, 44% on welfare as young adults, and 56% of next-generation young teen mothers. Children of prior teen mothers had increased risks for poor health and for educational and social outcomes nearly equal to those seen in children of teen mothers. Combined, these relatively few children experienced a large share of the negative outcomes occurring among young people. Our results suggest the need to expand the definition of risk associated with adolescent motherhood and target their children for enhanced medical and social services.

    2013-09-01

    Teen pregnancy is associated with a host of deleterious outcomes for girls such as drug use and poor parenting. Thus, reducing teen pregnancy rates could improve long-term developmental outcomes for girls, improving adjustment during young adulthood. Based on the positive effects of Multidimensional Treatment Foster Care (MTFC) relative to group care (GC) in a study of adolescent girls-significantly fewer pregnancies reported in the 2-year follow-up for MTFC girls-the present study followed this sample into young adulthood (approximately 7 years postbaseline) to examine the effects of adolescent pregnancy on young adult substance use and pregnancy-related outcomes. All participants were randomly assigned to MTFC (n = 81) or GC (n = 85) as adolescents as part of two RCTs. Results from logistic regression analyses indicated that becoming pregnant during the 2-year follow-up was significantly related to illicit drug use, miscarriage from a new pregnancy, and child welfare involvement at 7 years postbaseline. In addition, baseline marijuana use predicted marijuana use at 7 years postbaseline.

High school adolescents (n=1190) were enrolled over successive school semesters. The small-group sessions were presented during the school-lunch hours. Confidential surveys were conducted at baseline, immediate, six-, and 12-month postintervention for demographics, parental communication/monitoring, sexual risk behaviours and sexually transmitted diseases (STDs)/HIV/condom-usage knowledge. Sexually active participants were encouraged to volunteer for urine-based STDs testing at the School-Based Health Centres. Many (47.4%) students reported having had sexual intercourse at baseline. Overall behaviours changed towards 'safer' sex behaviours (intent-to-use and using condoms, communicating with partner/parents about sex/condoms/STDs) with time (Psexual activity (Psexual risk behaviours supported the effectiveness of this intervention.

    2011-04-08

    In 2009, approximately 410,000 teens aged 15-19 years gave birth in the United States, and the teen birth rate remains higher than in other developed countries. To describe U.S. trends in teen births and related factors, CDC used data on 1) teen birth rates during 1991-2009 from the National Vital Statistics System, 2) sexual intercourse and contraceptive use among high school students during 1991-2009 from the national Youth Risk Behavior Survey, and 3) sex education, parent communication, use of long-acting reversible contraceptives (LARCs), and receipt of reproductive health services among teens aged 15-19 years from the 2006-2008 National Survey of Family Growth. In 2009, the national teen birth rate was 39.1 births per 1,000 females, a 37% decrease from 61.8 births per 1,000 females in 1991 and the lowest rate ever recorded. State-specific teen birth rates varied from 16.4 to 64.2 births per 1,000 females and were highest among southern states. Birth rates for black and Hispanic teens were 59.0 and 70.1 births per 1,000 females, respectively, compared with 25.6 for white teens. From 1991 to 2009, the percentage of high school students who ever had sexual intercourse decreased from 54% to 46%, and the percentage of students who had sexual intercourse in the past 3 months but did not use any method of contraception at last sexual intercourse decreased from 16% to 12%. From 1999 to 2009, the percentage of students who had sexual intercourse in the past 3 months and used dual methods at last sexual intercourse (condoms with either birth control pills or the injectable contraceptive Depo-Provera) increased from 5% to 9%. During 2006-2008, 65% of female teens and 53% of male teens received formal sex education that covered saying no to sex and provided information on methods of birth control. Overall, 44% of female teens and 27% of male teens had spoken with their parents about both topics, but among teens who had ever had sexual intercourse, 20% of females and 31

  20. A SELF PROCESS IMPROVEMENT FOR ACHIEVING HIGH SOFTWARE QUALITY

    Directory of Open Access Journals (Sweden)

    DR. SHASHANK.D.JOSHI

    2011-05-01

    Full Text Available Quality has been one of the most important factors in judging any product. Quality means “a degree or grade of excellence or worth”. Quality is a term that is usually described using adjectives. Quality has several attributes to it, some of which can be quantified using metrics. These attributes such as usability, portability, security, performance, reliability etc have different importance in different projects. Different software quality assurance methods & practices have been used in different software projects to attain the true value. Quality is an attribute which is a distinct feature and it differs with people’s perception. Achieving high software quality involves measurement of software metrics and optimization based on estimated values. As the software systems grow larger, complexity ofdesign and implementation increases, and this in turn is more prone to defects and hence directly affect the quality of the systems. However, in any software project, high quality is always desirable, and many projects have specific quality requirements. Achieving high software quality involves measurement of software metrics and optimization based on estimated values. Developing high quality software is governed by factors such as people, process, technology and cost. This paper attempts to present a novel approach towards achieving high software quality in various kinds of projects under given constraints.

    2012-02-01

    Motor vehicle crashes (MVCs) are the leading cause of death among teenagers. Little is known about the content of US paediatrician counselling about teen driving. To examine US paediatrician knowledge, attitudes, and counselling patterns regarding teen driving. A random sample questionnaire was mailed to American Academy of Pediatrics members in 2009 (n=1606; response=875 (55%)). Analysis was limited to 596 paediatricians who provide adolescent checkups. Questions addressed counselling and attitudes towards roles in promoting safe driving. Logistic regression assessed the relationship between counselling topics and practice characteristics. Most (89%) respondents provide some counselling about driving. Two topics commonly discussed by paediatricians were seatbelts (87%) and alcohol use (82%). Less frequently discussed were: cell phones (47%), speeding (43%), and dangers of transporting teen passengers (41%). Topics rarely discussed were: night driving (21%), graduated driver licensing laws (13%), safe cars (9%), driver education (9%), fatigue (25%), and parental limit setting (23%). Only 10% ever recommend a parent-teen driver agreement. Paediatricians who had a patient injured or killed in an MVC were more likely to discuss night driving (OR=2.86). Physicians caring for a high proportion of adolescents (OR=1.83) or patients with private insurance (OR=1.85) counsel more about the risks of driving with teen passengers. Paediatricians in the USA support counselling on teen driving during routine office visits, but omit many important risk factors. Few recommend parent-teen driver agreements. Methods that help clinicians efficiently and effectively counsel families about teen driving should be developed.

  3. Parent Involvement Practices of High-Achieving Elementary Science Students

    Waller, Samara Susan

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

    2014-09-01

    Attention-deficit/hyperactivity disorder (ADHD) presents in childhood with inattention, hyperactivity, and impulsivity and is associated with functional impairments. These children tend to display a variety of disruptive behaviors, which may worsen in adolescence. Teens with ADHD may show high levels of defiance, posing significant challenges for parents. Early efforts to understand parenting in the context of teen ADHD reveal high levels of parental stress and reactivity in response to the teen's ADHD symptoms. Subsequent research recognized that some of these parents have ADHD or other psychopathology that may contribute to maladaptive parenting. However, some parents adjust and demonstrate optimism and resilience in the face of their teens' ADHD. Recent research has identified parental factors (eg, emotional intelligence) and interventions (eg, mindfulness training) that may improve parenting/teen relationships and the developmental outcomes of teens. This article explores parenting teens with ADHD with a focus on these novel interventions.

    Teens are avid users of new technologies and social media. Nearly 95% of US adolescents are online at least occasionally. Health care professionals and organizations that work with teens should identify online health information that is both accurate and teen friendly. Early studies indicate that some of the new health technology tools are acceptable to teens, particularly texting, computer-based psychosocial screening, and online interventions. Technology is being used to provide sexual health education, medication reminders for contraception, and information on locally available health care services.

    To describe the Teen Online Problem Solving-Teen Only (TOPS-TO) intervention relative to the original Teen Online Problem Solving-Family (TOPS-F) intervention, to describe a randomized controlled trial to assess intervention efficacy, and to report feasibility and acceptability of the TOPS-TO intervention. Research method and design: This is a multisite randomized controlled trial, including 152 teens (49 TOPS-F, 51 TOPS-TO, 52 IRC) between the ages of 11-18 who were hospitalized for a moderate to severe traumatic brain injury in the previous 18 months. Assessments were completed at baseline, 6-months post baseline, and 12-months post baseline. Data discussed include adherence and satisfaction data collected at the 6-month assessment (treatment completion) for TOPS-F and TOPS-TO. Adherence measures (sessions completed, dropout rates, duration of treatment engagement, and rates of program completion) were similar across treatment groups. Overall, teen and parent reported satisfaction was high and similar across groups. Teens spent a similar amount of time on the TOPS website across groups, and parents in the TOPS-F spent more time on the TOPS website than those in the TOPS-TO group (p = .002). Parents in the TOPS-F group rated the TOPS website as more helpful than those in the TOPS-TO group (p = .05). TOPS-TO intervention is a feasible and acceptable intervention approach. Parents may perceive greater benefit from the family based intervention. Further examination is required to understand the comparative efficacy in improving child and family outcomes, and who is likely to benefit from each approach.

  10. The Impact of Inclusive STEM High Schools on Student Achievement

    Directory of Open Access Journals (Sweden)

    Jennifer Gnagey

    2016-05-01

    Full Text Available This study is one of the first to estimate the impact of “inclusive“ science, technology, engineering, and mathematics (STEM high schools using student-level data. We use multiple statistical strategies to estimate the effect on student achievement from 2 years of attendance at six such high schools in Ohio. The results indicate that two schools had positive effects on science achievement that appear to come at the expense of achievement in social studies. The other schools had negligible or, often, negative effects across both STEM and, particularly, non-STEM subjects. These results are consistent with studies indicating that inclusive STEM schools typically focus on problem-based, personalized learning rather than science and mathematics content. The analysis also reveals the importance of accounting for students’ prior test scores in science, in addition to math and reading, when estimating models that use only 1 year of prior test score data—something that existing studies fail to do.

    High reliability as a corporate value in healthcare can be achieved by meeting the "Quadruple Aim" of improving population health, reducing per capita costs, enhancing the patient experience, and improving provider wellness. This drive starts with the board of trustees, CEO, and other senior leaders who ingrain high reliability throughout the organization. At WellStar Health System, the board developed an ambitious goal to become a top-decile health system in safety and quality metrics. To achieve this goal, WellStar has embarked on a journey toward high reliability and has committed to Lean management practices consistent with the Institute for Healthcare Improvement's definition of a high-reliability organization (HRO): one that is committed to the prevention of failure, early identification and mitigation of failure, and redesign of processes based on identifiable failures. In the end, a successful HRO can provide safe, effective, patient- and family-centered, timely, efficient, and equitable care through a convergence of people, processes, and technology.

    Parents play a fundamental role in teaching their children safe driving skills to reduce risk of motor vehicle crashes, the leading cause of death for teens. Steering Teens Safe is a new parent-based intervention that equips parents with communication skills to talk about, demonstrate, and practice safe driving behaviors and skills with their teens. This implementation evaluation focuses on a sample of 83 parents who delivered Steering Teens Safe to their teens. One-, 2- and 3-month follow-up assessments were conducted with intervention parents to evaluate the self-reported quantity and quality of talking about, demonstrating, and practicing safe driving goals with teens; perceived success and benefit of the program; and barriers to implementation. Over 3 months of follow-up, parents discussed driving goals with their teens for a median of 101.5 minutes. The most frequently addressed topics were general safety principles, including distracted driving, driving in bad weather, wearing a seat belt, and being a safe passenger. Parents spent a median of 30 minutes practicing safe driving skills such as changing lanes. Sixty-seven percent of parents talked to their children about rural road safety, but just 36% demonstrated and half practiced these skills with their teens. Barriers to implementation include time and opportunity barriers and resistant attitudes of their teens. However, barriers neither affected frequency of engagement nor parents' perceived benefit and comfort in delivering the program. Parents with time/opportunity barriers also had higher practice and demonstration times than parents without these barriers. Findings indicate high acceptability among parent implementers and promise for real-world delivery. Future studies are needed to assess intervention impact.

    Moms and Teens for Safe Dates (MTSD) is a dating abuse (DA) prevention program for teens exposed to domestic violence. In a randomized controlled trial (RCT), MTSD prevented certain types of DA victimization (psychological and physical) and perpetration (psychological and cyber) among teens with higher, but not lower, exposure to domestic violence. We built on these findings by using moderated mediation analysis to examine whether level of teen exposure to domestic violence conditioned the indirect effects of MTSD on these types of DA through targeted mediators. MTSD consisted of six mailed activity booklets. Mothers who had been former victims of domestic violence delivered the program to their teens. Mother and teen pairs were recruited into the RCT through community advertising and completed baseline and 6-month follow-up interviews (N = 277 pairs). As expected, MTSD had significant favorable effects for teens with higher but not lower exposure to domestic violence on several mediators that guided program content, including teen conflict management skills and mother-perceived severity of DA, self-efficacy for enacting DA prevention efforts, and comfort in communicating with her teen. MTSD had significant main effects on other mediators including teen feeling of family closeness and cohesion and mother-perceived susceptibility of her teen to DA. As expected, all significant indirect effects of MTSD on DA outcomes through mediators were for teens with higher exposure to domestic violence. Findings have implications for developing DA victimization and perpetration prevention programs for teens with high exposure to domestic violence.

    Virtual Machine Monitors (VMM) have become popular in different application areas. Some applications may require to generate the timer events with high resolution and precision. This however may be challenging due to the complexity of VMMs. In this paper we focus on the timer functionality provided by five different VMMs-Xen, KVM, Qemu, VirtualBox and VMWare. Firstly, we evaluate resolutions and precisions of their timer events. Apparently, provided resolutions and precisions are far too low for some applications (e.g. networking applications with the quality of service). Then, using Xen virtualization we demonstrate the improved timer design that greatly enhances both the resolution and precision of achieved timer events.

    Although teen pregnancy rates in the U.S. have recently declined, the need for programs for pregnant and parenting teens remains. This report presents information from 53 programs that served pregnant and parenting teens in New Mexico between 1997 and 2000. Data on 3,194 teens, including their characteristics, the services they received, and several key outcomes, are examined. These data indicate that the programs were successful in promoting educational attainment as well as gains in employment. Prevalence of late prenatal care and low birth weight babies was lower than statewide averages, and the rate of repeat pregnancy was lower than that reported by many other programs. How these programs achieved these results is discussed.

    Alabama is one of the five US states with the highest teen driving mortality. We recruited teen drivers to participate in a questionnaire regarding high-risk driving behaviors. Teens were recruited from a large county school system to participate in a voluntary anonymous survey. Questions were taken in part from the National Youth Risk Behavior Survey. Descriptive statistics and odds ratios with 95% confidence intervals were calculated. A total of 1023 teen drivers participated (46% boys, 47% African American, 39% white, 6% Latino, and 7% other). In all, 526 students (52%) reported inconsistent seat belt use. Half of the teens surveyed reported using a cellular telephone while driving within the past 30 days (51%); 10% admitted to driving after drinking alcoholic beverages in the past 30 days, with 23% saying they had ridden with a driver who had been drinking. High-risk teen driving behaviors were reported by many of the participants in our study. The majority of teens surveyed do not routinely wear seatbelts. Common misperceptions still exist regarding seatbelts and should be a focus of future education. Future research should focus on parental behaviors and correcting misperceptions of young drivers.

    The purpose of this pilot study was to test a community outreach model designed to help mothers in a rural, medically underserved area navigate their teen daughters to health department services for long-acting reversible contraception (LARC) or alternative contraception. The pilot study used a single-group, post-test only design. Mothers of teen daughters (N=142) received a 1-hour, one-to-one intervention session (in outreach settings) from Community Liaisons. Mothers received training on how to communicate with their daughters about LARC and other contraceptive methods. Data were collected from June through October 2014, and analyzed in September 2015. The authors re-contacted 104 of 142 mothers enrolled in the study, achieving a 73.2% retention rate. Of these, 12.5% had daughters receiving LARC. An additional 11.0% had daughters with health department-verified initiation of birth control pills. Only one correlate-whether a mother believed her daughter was having sex-was associated with receiving either LARC or birth control pills. Among those indicating they knew their daughters were having sex, 31.7% of the daughters received LARC/birth control pills. By contrast, among mothers not indicating they knew their daughters were having sex, only 2.9% had daughters receiving LARC or birth control pills. Findings suggest that an outreach-based program delivered directly to mothers of teen daughters may be a highly effective method for enhancing service utilization of LARC and the initiation of birth control pill use in a rural, medically underserved area.

    Full Text Available Teen Ambassador Leadership Kit, (TALK, is an annual weekend retreat designed for teens interested in promoting and marketing 4-H in their communities. TALK organizers felt teens would benefit from an intensive weekend retreat focused on communication. TALK produces a network of educated and excited 4-H teens that are available to help with 4-H promotion and marketing. Participants arrive on Friday evening for team building activities, on Saturday they participate in one of the workshops offered and on Sunday morning each workshop group has the opportunity to share their completed projects and what they learned. At the conclusion of the retreat, teens are designated "County 4-H Ambassadors" and certificates of completion, professional business cards and polo shirts are presented. The TALK teen participants return home to share what they learned with their local county 4-H staff and help promote and market 4-H in their communities.

  10. Computer Security: SAHARA - Security As High As Reasonably Achievable

    CERN Multimedia

    Stefan Lueders, Computer Security Team

    2015-01-01

    History has shown us time and again that our computer systems, computing services and control systems have digital security deficiencies. Too often we deploy stop-gap solutions and improvised hacks, or we just accept that it is too late to change things.    In my opinion, this blatantly contradicts the professionalism we show in our daily work. Other priorities and time pressure force us to ignore security or to consider it too late to do anything… but we can do better. Just look at how “safety” is dealt with at CERN! “ALARA” (As Low As Reasonably Achievable) is the objective set by the CERN HSE group when considering our individual radiological exposure. Following this paradigm, and shifting it from CERN safety to CERN computer security, would give us “SAHARA”: “Security As High As Reasonably Achievable”. In other words, all possible computer security measures must be applied, so long as ...

  11. Achieving High Resolution Timer Events in Virtualized Environment.

    Full Text Available Virtual Machine Monitors (VMM have become popular in different application areas. Some applications may require to generate the timer events with high resolution and precision. This however may be challenging due to the complexity of VMMs. In this paper we focus on the timer functionality provided by five different VMMs-Xen, KVM, Qemu, VirtualBox and VMWare. Firstly, we evaluate resolutions and precisions of their timer events. Apparently, provided resolutions and precisions are far too low for some applications (e.g. networking applications with the quality of service. Then, using Xen virtualization we demonstrate the improved timer design that greatly enhances both the resolution and precision of achieved timer events.

    The rapid development of very-large format infrared detector arrays has challenged the IR scene projector community to also develop larger-format infrared emitter arrays to support the testing of systems incorporating these detectors. In addition to larger formats, many scene projector users require much higher simulated temperatures than can be generated with current technology in order to fully evaluate the performance of their systems and associated processing algorithms. Under the Ultra High Temperature (UHT) development program, Santa Barbara Infrared Inc. (SBIR) is developing a new infrared scene projector architecture capable of producing both very large format (>1024 x 1024) resistive emitter arrays and improved emitter pixel technology capable of simulating very high apparent temperatures. During earlier phases of the program, SBIR demonstrated materials with MWIR apparent temperatures in excess of 1400 K. New emitter materials have subsequently been selected to produce pixels that achieve even higher apparent temperatures. Test results from pixels fabricated using the new material set will be presented and discussed. A 'scalable' Read In Integrated Circuit (RIIC) is also being developed under the same UHT program to drive the high temperature pixels. This RIIC will utilize through-silicon via (TSV) and Quilt Packaging (QP) technologies to allow seamless tiling of multiple chips to fabricate very large arrays, and thus overcome the yield limitations inherent in large-scale integrated circuits. Results of design verification testing of the completed RIIC will be presented and discussed.

  15. Linking Changes in Contraceptive Use to Declines in Teen Pregnancy Rates

    Directory of Open Access Journals (Sweden)

    Jennifer Manlove

    2015-12-01

    Full Text Available Using a unique microsimulation tool, Teen FamilyScape, the present study explores how changes in the mix of contraceptive methods used by teens contributed to the decline in the U.S. teen pregnancy rate between 2002 and 2010. Results indicate that changes in contraceptive use contributed to approximately half of the decline in the teen pregnancy rate during this time period (48% and that a little more than half of this “contraceptive effect” was due to an increase in teen condom use (58%. The remaining share of the contraceptive effect can be attributed to an increase in the use of more effective hormonal (pill, patch, ring and long-acting reversible contraceptive (LARC/injectable methods (Intrauterine Devices (IUD, implant and injectable. Results from an additional counterfactual analysis suggest that the contraceptive effect was driven by the fact that the percentage of teens using no birth control fell during the study time period, rather than by the fact that some teens switched from less effective methods (condoms to more effective hormonal and LARC/injectable methods. However, very high typical use failure rates for teen condom users suggest the need for a two-pronged approach for continuing reductions in teen pregnancy for sexually active teens: first, targeting the youth most at risk of not using contraception and helping them choose contraception, and second, increasing the effectiveness of method use among existing contraceptors.

  17. Technology and teen drivers.

    Science.gov (United States)

    Lee, John D

    2007-01-01

    The rapid evolution of computing, communication, and sensor technology is likely to affect young drivers more than others. The distraction potential of infotainment technology stresses the same vulnerabilities that already lead young drivers to crash more frequently than other drivers. Cell phones, text messaging, MP3 players, and other nomadic devices all present a threat because young drivers may lack the spare attentional capacity for vehicle control and the ability to anticipate and manage hazards. Moreover, young drivers are likely to be the first and most aggressive users of new technology. Fortunately, emerging technology can also support safe driving. Electronic stability control, collision avoidance systems, intelligent speed adaptation, and vehicle tracking systems can all help mitigate the threats to young drivers. However, technology alone is unlikely to make young drivers safer. One promising approach to tailoring technology to teen drivers is to extend proven methods for enhancing young driver safety. The success of graduated drivers license programs (GDL) and the impressive safety benefit of supervised driving suggest ways of tailoring technology to the needs of young drivers. To anticipate the effects of technology on teen driving it may be useful to draw an analogy between the effects of passengers and the effects of technology. Technology can act as a teen passenger and undermine safety or it can act as an adult passenger and enhance safety. Rapidly developing technology may have particularly large effects on teen drivers. To maximize the positive effects and minimize the negative effects will require a broad range of industries to work together. Ideally, vehicle manufacturers would work with infotainment providers, insurance companies, and policy makers to craft new technologies so that they accommodate the needs of young drivers. Without such collaboration young drivers will face even greater challenges to their safety as new technologies emerge.

    Zierold, Kristina M; Appana, Savi; Anderson, Henry A

    2012-02-01

    Recent controversy regarding the issue of children working in family-owned businesses has come to the forefront, pitting safety and health versus parent's right to teach their children the family trade. While studies have characterized injury among working teens, no studies have assessed work and injury among teens employed in family-owned businesses. This study is the first to examine teenagers working in family-owned businesses and to compare the experiences of teens working in family-businesses to the experiences of other working teens. A questionnaire was distributed to 8,085 teens in high schools throughout the five public health regions of Wisconsin. A total of 6, 810 teens responded (84%). Overall 2,858 high school teens aged 14-17 reported working (42%); of which 963 (34%) worked in a family-business. Teens working in family-businesses were more likely to report that their injury was severe, affecting their activities for more than three days, compared with other working teens (33% vs. 21%, P = 0.05). The percentage of teens working in family-businesses that reported broken bones or crushed body parts was 17% compared to only 5% of other-working teens. Additionally, teens employed in family-businesses were more likely to file for workers' compensation (28% vs. 12%, P = 0.005). Teens working in family-owned businesses may be at a greater risk for more severe injury based on the jobs and tasks they are doing. Teens working in family-owned businesses were more likely to report engaging in dangerous tasks, including some that are illegal under the Hazardous Occupation Orders. More research is needed to assess the dynamics that exist for teens working in family-owned businesses.

    Cota-Robles, Sonia; Pedersen, Laura; LeCroy, Craig Winston

    The purpose of this study was to evaluate breastfeeding practices of teen mothers in a pre- and postnatal education and support program. We studied breastfeeding practices of primarily Hispanic and non-Hispanic White teen mothers who participated in the Teen Outreach Pregnancy Services (TOPS) program, which promoted breastfeeding through prenatal programming and postpartum support. Analyses identified the most common reasons participants had not breastfed and, for those who initiated breastfeeding, the most common reasons they stopped. Participants (g = 314) reported on whether and for how long they breastfed. Nearly all participants reported initiating breastfeeding but few breastfed to 6 months. For the most part, reasons they reported stopping breastfeeding paralleled those previously reported for adult mothers across the first several months of motherhood. We found that teen mothers can initiate breastfeeding at high rates. Results highlight areas in which teen mothers' knowledge and skills can be supported to promote breastfeeding duration, including pain management and better recognizing infant cues. Our findings expand limited previous research investigating reasons that teen mothers who initiate breastfeeding stop before 6 months.

    Trice, Rodney Nathaniel

    This study examines the educational experiences of high achieving African American males. More specifically, it analyzes the influences on their successful navigation through high school science. Through a series of interviews, observations, questionnaires, science portfolios, and review of existing data the researcher attempted to obtain a deeper understanding of high achieving African American males and their limitations to academic attainment and high school science experiences. The investigation is limited to ten high achieving African American male science students at Woodcrest High School. Woodcrest is situated at the cross section of a suburban and rural community located in the southeastern section of the United States. Although this investigation involves African American males, all of whom are successful in school, its findings should not be generalized to this nor any other group of students. The research question that guided this study is: What are the limitations to academic attainment and the high school science experiences of high achieving African American males? The student participants expose how suspension and expulsion, special education placement, academic tracking, science instruction, and teacher expectation influence academic achievement. The role parents play, student self-concept, peer relationships, and student learning styles are also analyzed. The anthology of data rendered three overarching themes: (1) unequal access to education, (2) maintenance of unfair educational structures, and (3) authentic characterizations of African American males. Often the policies and practices set in place by school officials aid in creating hurdles to academic achievement. These policies and practices are often formed without meaningful consideration of the unintended consequences that may affect different student populations, particularly the most vulnerable. The findings from this study expose that high achieving African American males face major

    The current study examines whether adolescents who report sexting exhibit more psychosocial health problems, compared to their non-sexting counterparts. Participants included 937 ethnically diverse male and female adolescents recruited and assessed from multiple high schools in southeast Texas. Measures included self-report of sexting, impulsivity, alcohol and drug use, and depression and anxiety symptoms. Teen sexting was significantly associated with symptoms of depression, impulsivity, and substance use. When adjusted for prior sexual behavior, age, gender, race/ethnicity, and parent education, sexting was only related to impulsivity and substance use. While teen sexting appears to correlate with impulsive and high-risk behaviors (substance use), we did not find sexting to be a marker of mental health.

    Urgent measures are required to stop the increase in the frequency of pregnancies and sexually transmitted diseases among teenagers. A means of facing this problem is promoting sexual abstinence among youngsters. There are studies that confirm the efficacy of this approach. To show the results of the application of a holistic sexuality program (TeenSTAR) among Chilean teenagers. Students attending basic or high school were divided into a control or study group. The control group (342 students) received the usual education on sexuality given by their schools and the study group (398 students) participated in twelve TeenSTAR sessions lasting 1.5 hours each, given by a trained professor. Assessment of achievements was made using an anonymous questionnaire answered at the start and end of the program. The rates of sexual initiation among control and study groups were 15 and 6.5%, respectively. Among sexually active students, 20% of those in the study group and 9% of those in the control group discontinued sexual activity. A higher proportion of students in the TeenSTAR program retarded their sexual initiation or discontinued sexual activity and found more reasons to maintain sexual abstinence than control students.

    Inexperienced, less-skilled driving characterises many newly licensed drivers and contributes to high crash rates. A randomised trial of TeenDrivingPlan (TDP), a new learner driver phase internet-based intervention, demonstrated effectiveness in improving safety relevant, on-road driving behaviour, primarily through greater driving practice diversity. To inform future learner driver interventions, this analysis examined TDP use and its association with practice diversity. Posthoc analysis of data from teen/parent dyads (n=107), enrolled early in learner phase and assigned to treatment arm in randomised trial. Inserted software beacons captured TDP use data. Electronic surveys completed by parents and teens assessed diversity of practice driving and TDP usability ratings at 24 weeks (end of study period). Most families (84%) used TDP early in the learner period; however, the number of TDP sessions in the first week was three times higher among dyads who achieved greater practice diversity than those with less. By week five many families still engaged with TDP, but differences in TDP use could not be detected between families with high versus low practice diversity. Usability was not a major issue for this sample based on largely positive user ratings. An engaging internet-based intervention, such as TDP, can support families in achieving high practice diversity. Future learner driver interventions should provide important information early in the learner period when engagement is greatest, encourage continued learning as part of logging practice drives, and incorporate monitoring software for further personalisation to meet family needs.

  2. Achieving Timeliness and High Throughput Metrics in Dissemination Systems

    Directory of Open Access Journals (Sweden)

    MANNE ANUSHA

    2012-09-01

    Full Text Available Existing systems for information dissemination is inadequate and typically results in information gaps. The lack of a clear concise system for information dissemination makes it difficult to determine the most efficient and effective way to pass information especially in the fields of ecommerce and security alerting systems to the appropriate parties. These systems usually require that the desired information be matched between numerous sources and sinks based on established subscriptions. Timeliness and Throughput are performance metrics used for evaluation. And these existing systems fail to achieve a balance between the two. So a much better system termed INFOD (INFOrmation Dissemination was proposed earlier that achieves a balance between performance metrics. We observed that an Integrated Control Loop used by admission control scheme of INFOD employs PL/SQL stored procedures that are huge computation overhead. We propose to replace them with Java stored procedures that can tremendously increase the performance.

    In the U.S. teen mothers are more likely to give birth to low birth weight babies than non-teen mothers. There is also substantial evidence that smoking is a risk factor correlated with low birth weight. Low birth weight is a costly outcome in both the short and long term for parents, children, and society at large. This paper examines the causal link between teen age smoking behavior and low birth weight. We use a variety of empirical techniques including fixed effects and a matching estimat...

    Dobbins, Christopher C; Kenney, Brittain N; Meier, Carrie E; Taormina, Velma V

    Unintended pregnancies are typically associated with poor health outcomes for mothers and babies, and they also limit the social mobility of women and their families. Gaston County has achieved great success in reducing both teen pregnancies and unintended pregnancies among low-income women through the Gaston Youth Connected project and the local health department's push to increase accessibility to long-acting reversible contraception. Reductions in the racial disparities in teen pregnancy rates, higher graduation rates for females, and fewer pregnancies among low-income women all indicate a potential for better reproductive health to increase the social mobility of Gaston County women. The ability to clearly connect health outcomes to long-term social improvements helps create sustainable community buy-in and should be a priority in public health initiatives.

    Marryshow, Derrick; Hurley, Eric A; Allen, Brenda A; Tyler, Kenneth M; Boykin, A Wade

    2005-01-01

    This study examined Ogbu's widely accepted thesis that African American students reject high academic achievement because they perceive its limited utility in a world where their upward mobility is constrained by racial discrimination. Boykin's psychosocial integrity model contends that Black students value high achievement but that discrepancies between their formative cultural experiences and those imposed in school lead them to reject the modes of achievement available in classrooms. Ninety Black children completed a measure of attitudes toward students who achieve via mainstream or African American cultural values. Participants rejected the mainstream achievers and embraced the African American cultural achievers. Moreover, they expected their teachers to embrace the mainstream achievers and reject those who achieved through high-verve behavior. Results suggest that Boykin's thesis is a needed refinement to Ogbu's ideas. They indicate that Black children may reject not high achievement but some of the mainstream cultural values and behaviors on which success in mainstream classrooms is made contingent.

    2013-07-01

    Full Text Available Ultra-High Performance Concrete (UHPC is a relatively new concrete. According to [11] UHPC is that concrete which features compressive strength over C100/115 class. Up to this point standards for this type of concrete were not adopted, although its characteristic strength exceeds those specified in [33]. Its main property is high compressive strength. This provides the possibility of reducing the section of elements (beams or columns made of this type of concrete, while the load capacity remains high. The study consists in blending mixtures of UHPC made of varying proportions of materials. The authors have obtained strengths of up to 160 MPa. The materials used are: Portland cement, silica fume, quartz powder, steel fibers, superplasticiser, sand and crushed aggregate for concrete - andesite.

    2000-04-01

    To ascertain views of public high school students on preventing teen pregnancy. The authors hypothesized that students at varying risk for pregnancy (e.g., abstinent, consistent contraceptors, inconsistent contraceptors) would have differing views which would have implications for future pregnancy prevention programming. A 75-question anonymous survey designed for this study was administered in six Boston high schools. The sample consisted of 49% females and 51% males in 10th and 11th grades from diverse racial and ethnic backgrounds. One thousand surveys were received and analyzed using Chi-square tests to assess statistically significant differences in student responses. Sixty-three percent of the students had had sexual intercourse: 72% of males and 54% of females. Of these, 35% were consistent contraceptors and 65% were inconsistent. Students believed that having more information on pregnancy and birth control (52%), education about relationships (33%), parental communication (32%), improved contraceptive access (31%), and education about parenting realities (30%) would prevent teen pregnancy. Abstinent teens were more likely (58%) to say that information on pregnancy and birth control was important (pteens were more likely (40%) to identify greater access to birth control (p Teens using contraception were also more likely to be having frequent conversations with parents (49%) (pTeens report that having more information from parents, school, and health arenas can prevent pregnancy. Abstinent, consistent contraceptors, and inconsistent contraceptors have different preferences regarding strategies. This information has important implications for educational content and policy discussions.

  19. Raising the voices of teens to change sexuality education.

    Science.gov (United States)

    Wilson, S N

    2000-01-01

    In the US, birth, pregnancy, and abortion rates have remained unacceptably high despite the declines experienced over the years. According to the US Centers for Disease Control and Prevention, 65% of teens engage in sexual intercourse before they graduate from high school, 18% of 9th-grade students initiate intercourse before age 13, and approximately 4 million teens in the US contract a sexually transmitted disease each year. The country's response on these dismal statistics have been unsuccessful, focusing only on abstinence-only-until-marriage programs that are forbidden to discuss contraception and disease-prevention strategies. In view of this, the Network for Family Life Education launched the national newsletter and Web site ¿SEX, ETC¿. The goal was to provide up-to-date, accurate, balanced, and attractive materials that would change students' sexuality attitudes and behaviors. Developed by teens for teens, such an approach can push the envelope as to the kind of programs a school should implement if educators, administrators, and school board members will pay attention. Moreover, the approach holds the potential for an extraordinary new partnership between teens and caring adults that can move relevant, responsible sexuality education forward in a powerful and meaningful way.

  20. Achieving High Reliability Operations Through Multi-Program Integration

    Energy Technology Data Exchange (ETDEWEB)

    Holly M. Ashley; Ronald K. Farris; Robert E. Richards

    2009-04-01

    Over the last 20 years the Idaho National Laboratory (INL) has adopted a number of operations and safety-related programs which has each periodically taken its turn in the limelight. As new programs have come along there has been natural competition for resources, focus and commitment. In the last few years, the INL has made real progress in integrating all these programs and are starting to realize important synergies. Contributing to this integration are both collaborative individuals and an emerging shared vision and goal of the INL fully maturing in its high reliability operations. This goal is so powerful because the concept of high reliability operations (and the resulting organizations) is a masterful amalgam and orchestrator of the best of all the participating programs (i.e. conduct of operations, behavior based safety, human performance, voluntary protection, quality assurance, and integrated safety management). This paper is a brief recounting of the lessons learned, thus far, at the INL in bringing previously competing programs into harmony under the goal (umbrella) of seeking to perform regularly as a high reliability organization. In addition to a brief diagram-illustrated historical review, the authors will share the INL’s primary successes (things already effectively stopped or started) and the gaps yet to be bridged.

  1. Telescoping Solar Array Concept for Achieving High Packaging Efficiency

    2015-01-01

    Lightweight, high-efficiency solar arrays are required for future deep space missions using high-power Solar Electric Propulsion (SEP). Structural performance metrics for state-of-the art 30-50 kW flexible blanket arrays recently demonstrated in ground tests are approximately 40 kW/cu m packaging efficiency, 150 W/kg specific power, 0.1 Hz deployed stiffness, and 0.2 g deployed strength. Much larger arrays with up to a megawatt or more of power and improved packaging and specific power are of interest to mission planners for minimizing launch and life cycle costs of Mars exploration. A new concept referred to as the Compact Telescoping Array (CTA) with 60 kW/cu m packaging efficiency at 1 MW of power is described herein. Performance metrics as a function of array size and corresponding power level are derived analytically and validated by finite element analysis. Feasible CTA packaging and deployment approaches are also described. The CTA was developed, in part, to serve as a NASA reference solar array concept against which other proposed designs of 50-1000 kW arrays for future high-power SEP missions could be compared.

    2011-01-01

    High levels of youth employment, workplace hazards, and characteristics unique to adolescents contribute to a relatively high incidence of injuries among teens in the restaurant industry. This article discusses the ProSafety model of injury prevention among teen restaurant workers. Through integration with an existing career and technical education program, the ProSafety project seeks to prevent occupational injuries among the teen worker population through classroom safety education and internship skills reinforcement. ProSafety is the product of an innovative collaboration with occupational health nurses, business professionals, educators, and government. Its approach is derived from Social Cognitive Theory, is consistent with key values and strategies of occupational health nurses, and provides lessons for practitioners seeking to reduce occupational injuries in food service or among other populations of adolescent workers.

  13. Contraceptive considerations in overweight teens.

    Science.gov (United States)

    Kaneshiro, Bliss; Edelman, Alison

    2011-10-01

    The purpose of this review is to explore the efficacy and safety of contraceptives in overweight adolescents. There are few studies exploring hormonal contraceptive efficacy and safety in overweight and obese adults and almost none addressing these issues in adolescents. Luckily for teens, in terms of safety, many of the comorbidities associated with obesity are yet to transpire and their options for contraception remain relatively unrestricted. Studies of the combined oral contraceptive pill and patch in adults suggest that efficacy may be decreased in overweight adolescents. There is no evidence to suggest that the efficacy of the contraceptive implant or intrauterine device (IUD) is decreased in overweight adolescents. Indeed, these long-acting reversible methods will be the best choice for many adolescents because of their high efficacy. Although the literature is not definitive, there is probably a subset of adolescents who are susceptible to weight gain with use of depot medroxyprogesterone acetate. Although there is little research regarding contraceptive efficacy in overweight adolescents, IUDs and implants will be the best methods for many adolescents because of their high efficacy, reversibility, and safety.

  14. Rectangular Dielectric-loaded Structures for Achieving High Acceleration Gradients

    Science.gov (United States)

    Wang, Changbiao; Yakovlev, V. P.; Marshall, T. C.; LaPointe, M. A.; Hirshfield, J. L.

    2006-11-01

    Rectangular dielectric-loaded structures are described that may sustain higher acceleration gradients than conventional all-metal structures with similar apertures. One structure is a test cavity designed to ascertain the breakdown limits of dielectrics, while a second structure could be the basis for a two-beam accelerator. CVD diamond is an attractive dielectric for a high-gradient structure, since the published DC breakdown limit for CVD diamond is ˜ 2 GV/m, although the limit has never been determined for RF fields. Here we present a design of a diamond-lined test cavity to measure the breakdown limit. The designed cavity operates at 34 GHz, where with 10-MW input power it is expected to produce an ˜800 MV/m field on the diamond surface—provided breakdown is avoided. The two channel rectangular dielectric-loaded waveguide could be a two-beam accelerator structure, in which a drive beam is in one channel and an accelerated beam is in the other. The RF power produced by drive bunches in the drive channel is continuously coupled to the acceleration channel. The ratio of fields in the channels (transformer ratio) for the operating mode can be designed by adjusting the dimensions of the structure. An example of the two-channel structure is described, in which a train of five 3-nC drive bunches excites wake fields in the accelerator channel of up to 1.3 GV/m with a transformer ratio of 10 for the design mode.

  15. Achieving High-Frequency Optical Control of Synaptic Transmission

    The optogenetic tool channelrhodopsin-2 (ChR2) is widely used to excite neurons to study neural circuits. Previous optogenetic studies of synapses suggest that light-evoked synaptic responses often exhibit artificial synaptic depression, which has been attributed to either the inability of ChR2 to reliably fire presynaptic axons or to ChR2 elevating the probability of release by depolarizing presynaptic boutons. Here, we compare light-evoked and electrically evoked synaptic responses for high-frequency stimulation at three synapses in the mouse brain. At synapses from Purkinje cells to deep cerebellar nuclei neurons (PC→DCN), light- and electrically evoked synaptic currents were remarkably similar for ChR2 expressed transgenically or with adeno-associated virus (AAV) expression vectors. For hippocampal CA3→CA1 synapses, AAV expression vectors of serotype 1, 5, and 8 led to light-evoked synaptic currents that depressed much more than electrically evoked currents, even though ChR2 could fire axons reliably at up to 50 Hz. The disparity between optical and electrical stimulation was eliminated when ChR2 was expressed transgenically or with AAV9. For cerebellar granule cell to stellate cell (grc→SC) synapses, AAV1 also led to artificial synaptic depression and AAV9 provided superior performance. Artificial synaptic depression also occurred when stimulating over presynaptic boutons, rather than axons, at CA3→CA1 synapses, but not at PC→DCN synapses. These findings indicate that ChR2 expression methods and light stimulation techniques influence synaptic responses in a neuron-specific manner. They also identify pitfalls associated with using ChR2 to study synapses and suggest an approach that allows optogenetics to be applied in a manner that helps to avoid potential complications.

    The Teen Choice Program in New York City was described and the outcome of the program evaluation was reported. Teen Choice is a school based sex education and pregnancy prevention program run by trained social workers. The aim is to provide information, counseling, and referrals on a range of issues relating to sexuality. The program is elective and meets during a regularly scheduled gym period for one or two semesters from the 7th to the 12th grades. There are single sex and coeducational classes. The program aim is to change attitudes toward birth control, to change risky sexual behavior, such as unprotected coitus, to offer accurate knowledge about contraception, and to prevent unplanned pregnancies. Abstinence is encouraged, but for those sexually experienced, there is attention to responsible and reliable use of contraception. Program methods include small group discussion, individual counseling, and classroom discussion. Topics of discussion range from sexuality issues and birth control to values clarification and peer pressure. Small groups may discuss human sexual growth, relationship formation, family life, responsibility to self and others, consequences of teenage pregnancy, and social and cultural peer pressures. Girls are encouraged to assume more assertive and less reactive roles. Communication skills are reinforced in respectful exchanges of personal views and questions. Differentiating facts and issues is a primary focus. A question about when an individual first had sex would be redirected to asking about the appropriate age to first have sex. Respect for privacy helps to build students confidence in the program. A longitudinal evaluation conducted between 1984 and 1987 found that the program was effective in reaching and recruiting high risk adolescents. Students left the program with increased knowledge about contraception, more mature and responsible attitudes about the use of birth control, and reduced frequency of unprotected coitus. Boys were

    1997-02-01

    The purpose of this study was to describe the childbearing African American teens' perceptions of parenting based on their own experiences. Focus group discussions were held with 17 teens in their school setting for 50 minutes each week. Group discussions were audiotaped, tapes were transcribed, and then analyzed for common themes. The unmarried teens ranged in age from 15 to 18 years. Findings indicated that the teens depended on grandmothers to provide child care and for information about parenting. The teens identified parenting problems including crying, discipline, and conflicts dealing with grandmothers and the child's father. Teens wanted more information about breastfeeding and minor childhood diseases. The researchers identified that teens lacked information about their children's growth and development and safety issues. Findings have implications for nurses who care for childbearing teens and their children; and those involved in planning and implementing parent education programs for African American teen mothers and their families. Further research is indicated with larger samples of African American teens; and to explore the context of family relationships in which teen mothers and grandmothers share parenting for the teens' children.

  1. Teen theaters grapple with issues.

    Science.gov (United States)

    Pugni, J L

    1984-01-01

    At this time there are about 20 Planned Parenthood teen theater groups throughout the US. The idea originated in New York in 1973, when the staff of the Family Planning Division of the New York Medical College needed an effective way to reach adolescents about important issues. FOCUS, a teen family life theater sponsored by Planned Parenthood of Greater Charlotte, performs skits about life as seen from the teenager's perspective. The teenagers do not use a script but create their performances from their own experiences, expressed through carefully learned improvisational techniques. This approach gives the presentations an authentic flavor that enables the troupe to connect with the audience. The topics dealt with vary. For example, 1982-83 shows included peer pressure, divorce, teenage pregnancy, drinking, teenage suicide, parent-teen relationships, and loneliness. The performances do not offer absolute answers but rather pose important questions to the audience. Following the performance the actors and actresses return to the stage, still portraying their characters, and invite the audience to ask questions and discuss possible alternatives for the characters. THE SOURCE is the Teen Council of Planned Parenthood of Southwest Florida. It works to inform the community of problems teenagers face by presenting short plays, written, directed, and cast by teens themselves. Through education, honest answers, healthy building of self esteem, and parent support, SOURCE members reach a higher level of self awareness. They then share what they learn with their families, peers, and the community through performance and special events. THE SOURCE, formed in October 1980, grew out of Planned Parenthood's belief that if teens feel self worth, their decision-making process will be affected less by peer pressure and negative social influences.

    2010-08-01

    Full Text Available Objective: To increase teen seat belt use among drivers at a rural high school by implementing the Drive Alive Pilot Program (DAPP, a theory-driven intervention built on highway safety best practices.Methods: The first component of the program was 20 observational teen seat belt surveys conducted by volunteer students in a high school parking lot over a 38-month period before and after the month-long intervention. The survey results were published in the newspaper. The second component was the use of incentives, such as gift cards, to promote teen seat belt use. The third component involved disincentives, such as increased police patrol and school policies. The fourth component was a programmatic intervention that focused on education and media coverage of the DAPP program.Results: Eleven pre-intervention surveys and nine post-intervention surveys were conducted before and after the intervention. The pre- and post-intervention seat belt usage showed significant differences (p<0.0001. The average pre-intervention seat belt usage rate was 51.2%, while the average post-intervention rate was 74.5%. This represents a percentage point increase of 23.3 in seat belt use after the DAPP intervention.Conclusion: Based on seat belt observational surveys, the DAPP was effective in increasing seat belt use among rural high school teenagers. Utilizing a theory-based program that builds on existing best practices can increase the observed seat belt usage among rural high school students. [West J Emerg Med. 2010; 11(3: 280-283.

    2013-07-01

    The consequences of teen pregnancy have a substantial negative impact on both the teen mother and her child. Recent evidence clearly supports parenting education as the most effective means for improving adolescent parenting skills. This study evaluated the effectiveness of a school-based program using an evidence-based educational intervention to improve parenting style in high school teen mothers. Teen mothers, from 15 to 18 years of age, in a Title 1 high school were recruited from the Early Head Start program. Two groups of teens (N = 10) completed a pre-parenting style survey, enrolled in an 8- or 12-week group educational session, and completed a post-parenting style survey. While quantitative data did not yield a change in parenting style, qualitative findings highlighted a strong need for teens to "tell their story" and to share personal experiences related to parenting. These findings lend support for the role of parenting educational interventions in high schools with teens at high risk for pregnancy.

  12. Playing Legislative Catch-up in 2010 with a Growing, High-Tech Phenomenon: Evolving Statutory Approaches for Addressing Teen Sexting

    Directory of Open Access Journals (Sweden)

    Clay Calvert

    2011-04-01

    Full Text Available This article analyzes and critiques legislation adopted by states in 2010 to address the burgeoning phenomenon of teen sexting. Sixteen different states in 2010, stretching from California to New York, considered bills or resolutions designed to address, in one manner or another, teen sexting. By early November 2010, sexting bills had been signed into law by the governors of Arizona, Connecticut, Illinois and Louisiana. To illustrate the differences, as well as the strengths and weaknesses among the new sexting laws, the article applies each of them to the facts of realistic sexting scenario. Significantly, this analysis of the laws through the lens of hypothetical fact pattern reveals that the low-tech, downstream transmission of hard copies of sexual images of minors – images that were initially transmitted by cell phones by minors – appears to escape the reach of all of the 2010 sexting laws. The article argues that this gap or loophole in the new laws should be addressed by amending them. Ultimately, the article demonstrates a distinct lack of uniformity across the sexting statutes adopted in 2010. For instance, even when it comes to what would appear to be the most objective element of the offense of sexting – the maximum age of the possible perpetrator – there is disagreement. Such disparity creates an uneven patchwork of legislation that fails to give minors proper notice of what sexting activities are permissible.

    2014-01-01

    Novice teen drivers have long been known to have an increased risk of crashing, as well as increased tendencies toward unsafe and risky driving behaviors. Teens are unique as drivers for several reasons, many of which have implications specifically in the area of distracted driving. This paper reviews several of these features, including the widespread prevalence of mobile device use by teens, their lack of driving experience, the influence of peer passengers as a source of distraction, the role of parents in influencing teens’ attitudes and behaviors relevant to distracted driving and the impact of laws designed to prevent mobile device use by teen drivers. Recommendations for future research include understanding how engagement in a variety of secondary tasks by teen drivers affects their driving performance or crash risk; understanding the respective roles of parents, peers and technology in influencing teen driver behavior; and evaluating the impact of public policy on mitigating teen crash risk related to driver distraction.

  2. Approaches to achieve high grain yield and high resource use efficiency in rice

    Directory of Open Access Journals (Sweden)

    Jianchang YANG

    2015-06-01

    Full Text Available This article discusses approaches to simultaneously increase grain yield and resource use efficiency in rice. Breeding nitrogen efficient cultivars without sacrificing rice yield potential, improving grain fill in later-flowering inferior spikelets and enhancing harvest index are three important approaches to achieving the dual goal of high grain yield and high resource use efficiency. Deeper root distribution and higher leaf photosynthetic N use efficiency at lower N rates could be used as selection criteria to develop N-efficient cultivars. Enhancing sink activity through increasing sugar-spikelet ratio at the heading time and enhancing the conversion efficiency from sucrose to starch though increasing the ratio of abscisic acid to ethylene in grains during grain fill could effectively improve grain fill in inferior spikelets. Several practices, such as post-anthesis controlled soil drying, an alternate wetting and moderate soil drying regime during the whole growing season, and non-flooded straw mulching cultivation, could substantially increase grain yield and water use efficiency, mainly via enhanced remobilization of stored carbon from vegetative tissues to grains and improved harvest index. Further research is needed to understand synergistic interaction between water and N on crop and soil and the mechanism underlying high resource use efficiency in high-yielding rice.

    2010-07-01

    Using the National Longitudinal Study of Adolescent Health, factors associated with incongruence between parents' and adolescents' reports of teens' sexual experience were investigated, and the consequences of inaccurate parental knowledge for adolescents' subsequent sexual behaviors were explored. Most parents of virgins accurately reported teens' lack of experience, but most parents of teens who had had sex provided inaccurate reports. Binary logistic regression analyses showed that many adolescent-, parent-, and family-level factors predicted the accuracy of parents' reports. Parents' accurate knowledge of their teens' sexual experience was not found to be consistently beneficial for teens' subsequent sexual outcomes. Rather, parents' expectations about teens' sexual experience created a self-fulfilling prophecy, with teens' subsequent sexual outcomes conforming to parents' expectations. These findings suggest that research on parent-teen communication about sex needs to consider the expectations being expressed, as well as the information being exchanged.

    Magnesium alloys are highly desirable for a wide range of lightweight structural components. However, rolling Mg alloys can be difficult due to their poor plasticity, and the strong texture yielded from rolling often results in poor plate forming ability, which limits their further engineering applications. Here we report a new hard-plate rolling (HPR) route which achieves a large reduction during a single rolling pass. The Mg-9Al-1Zn (AZ91) plates processed by HPR consist of coarse grains of 30-60 μm, exhibiting a typical basal texture, fine grains of 1-5 μm and ultrafine (sub) grains of 200-500 nm, both of the latter two having a weakened texture. More importantly, the HPR was efficient in gaining a simultaneous high strength and uniform ductility, i.e., ~371 MPa and ~23%, respectively. The superior properties should be mainly attributed to the cooperation effect of the multimodal grain structure and weakened texture, where the former facilitates a strong work hardening while the latter promotes the basal slip. The HPR methodology is facile and effective, and can avoid plate cracking that is prone to occur during conventional rolling processes. This strategy is applicable to hard-to-deform materials like Mg alloys, and thus has a promising prospect for industrial application.

  19. The impact of collective teacher efficacy on student achievement in high school science

    Science.gov (United States)

    Burcham, Mark W.

    This dissertation was designed to examine the impact of collective teacher efficacy on high school science achievement by looking at relationships among collective teacher efficacy, its two constructs, group competence and group task analysis, and high school science achievement scores at four rural high schools in Northwestern North Carolina. The researcher gathered historical test data from the testing coordinator from the school system and then administered the Collective Teacher Efficacy Instrument, developed by Goddard, Hoy, and Woolfolk Hoy (2000), to 24 science teachers from the four high schools. Using this information, the researcher conducted statistical analyses to determine the relationships among collective teacher efficacy, group competence, and group task analysis as compared with the tested science curriculum (physical science, biology, chemistry, and physics). The researcher also examined which construct was the most contributing factor and examined differences in efficacy levels and student achievement levels at each high school. Analysis of the data from this study indicated collective teacher efficacy, as well as its two constructs, group competence and group task analysis, does have a positive impact on student achievement in high school science. Analysis of the data revealed group competence is the major contributing factor for student achievement in biology and group task analysis is the major contributing factor for student achievement in physical science, chemistry, and physics. Further analysis of the data in this study, also revealed that the two high schools with the highest levels of collective teacher efficacy had the highest levels of student achievement.

    Full Text Available Abstract Background In order to achieve a change among teens' sexual behavior, an important step is to improve our knowledge about their opinions concerning relationships, love and sexuality. Methods A questionnaire including topics on relationships, love and sexuality was distributed to a target population of 4,000 Filipino students from third year high school to third year college. Participants were obtained through multi-stage sampling of clusters of universities and schools. This paper concentrates on teens aged 13 to 18. Results Students reported that they obtained information about love and sexuality mainly from friends. However, they valued parents' opinion more than friends'. They revealed few conversations with their parents on these topics. A majority of them would like to have more information, mainly about emotion-related topics. Almost half of respondents were not aware that condoms are not 100% effective in preventing STIs or pregnancies. More girls, compared to boys, were sensitive and opposed to several types of sexism. After adjusting for sex, age and institution, the belief of 100% condom effectiveness and the approval of pornography and sexism were associated with being sexually experienced. Conclusion There is room for further encouraging parents to talk more with their children about sexuality, specially aspects related to feelings and emotions in order to help them make better sexual choices. Indeed, teens wish to better communicate with their parents on these issues. Condoms are regarded as safer than what they really are by almost half of the participants of this study, and such incorrect knowledge seems to be associated with sexual initiation.

  4. Decreased latent inhibition is associated with increased creative achievement in high-functioning individuals.

    Reductions in latent inhibition (LI), the capacity to screen from conscious awareness stimuli previously experienced as irrelevant, have been generally associated with the tendency towards psychosis. However, "failure" to screen out previously irrelevant stimuli might also hypothetically contribute to original thinking, particularly in combination with high IQ. Meta-analysis of two studies, conducted on youthful high-IQ samples. demonstrated that high lifetime creative achievers had significantly lower LI scores than low creative achievers (r(effect size) = .31, p = .0003, one-tailed). Eminent creative achievers (participants under 21 years who reported unusually high scores in a single domain of creative achievement) were 7 times more likely to have low rather than high LI scores, chi2 (1, N = 25) = 10.69, phi = .47. p = .003.

    Objectives We reviewed the literature focused on socioeconomic influences on teen childbearing and suggested directions for future research and practice related to this important indicator of teen sexual health. Methods We conducted an electronic search of Medline, ERIC, PsychLit, and Sociological Abstracts databases for articles published from January 1995 to November 2011. Selected articles from peer-reviewed journals included original quantitative analyses addressing socioeconomic influences on first birth among teen women in the U.S. Articles were abstracted for key information, ranked for quality according to the U.S. Preventive Services Task Force guidelines, assessed for bias, and synthesized. Results We selected articles with a range of observational study designs. Risk for bias varied across studies. All 12 studies that considered socioeconomic factors as influences on teen childbearing (vs. moderators or mediators of other effects) reported at least one statistically significant association relating low socioeconomic status, underemployment, low income, low education levels, neighborhood disadvantage, neighborhood physical disorder, or neighborhood-level income inequality to teen birth. Few reports included any associations contradicting this pattern. Conclusions This review suggests that unfavorable socioeconomic conditions experienced at the community and family levels contribute to the high teen birth rate in the U.S. Future research into social determinants of sexual health should include multiple levels of measurement whenever possible. Root causes of teen childbearing should be evaluated in various populations and contexts. Interventions that address socioeconomic influences at multiple levels could positively affect large numbers of teens and help eliminate disparities in teen childbearing. PMID:23450881

    2009-01-01

    Low-achieving readers in Grade 5 often lack comprehension strategies, domain knowledge, word recognition skills, fluency, and motivation to read. Students with such multiple reading needs seem likely to benefit from instruction that supports each of these reading processes. The authors tested this expectation experimentally by comparing the effects of Concept-Oriented Reading Instruction (CORI) with traditional instruction (TI) on several outcomes in a 12-week intervention for low achievers and high achievers. Low achievers in the CORI group were afforded explicit instruction, leveled texts, and motivation support. Compared with TI students, CORI students scored higher on posttest measures of word recognition speed, reading comprehension on the Gates-MacGinitie Reading Test, and ecological knowledge. CORI was equally effective for lower achievers and higher achievers. Explicitly supporting multiple aspects of reading simultaneously appeared to benefit diverse learners on a range of reading outcomes.

    Teen childbearing can have negative health, economic, and social consequences for mothers and their children (1) and costs the United States approximately $9.4 billion annually (2). During 1991-2014, the birth rate among teens aged 15-19 years in the United States declined 61%, from 61.8 to 24.2 births per 1,000, the lowest rate ever recorded (3). Nonetheless, in 2014, the teen birth rate remained approximately twice as high for Hispanic and non-Hispanic black (black) teens compared with non-Hispanic white (white) teens (3), and geographic and socioeconomic disparities remain (3,4), irrespective of race/ethnicity. Social determinants associated with teen childbearing (e.g., low parental educational attainment and limited opportunities for education and employment) are more common in communities with higher proportions of racial and ethnic minorities (4), contributing to the challenge of further reducing disparities in teen births. To examine trends in births for teens aged 15-19 years by race/ethnicity and geography, CDC analyzed National Vital Statistics System (NVSS) data at the national (2006-2014), state (2006-2007 and 2013-2014), and county (2013-2014) levels. To describe socioeconomic indicators previously associated with teen births, CDC analyzed data from the American Community Survey (ACS) (2010-2014). Nationally, from 2006 to 2014, the teen birth rate declined 41% overall with the largest decline occurring among Hispanics (51%), followed by blacks (44%), and whites (35%). The birth rate ratio for Hispanic teens and black teens compared with white teens declined from 2.9 to 2.2 and from 2.3 to 2.0, respectively. From 2006-2007 to 2013-2014, significant declines in teen birth rates and birth rate ratios were noted nationally and in many states. At the county level, teen birth rates for 2013-2014 ranged from 3.1 to 119.0 per 1,000 females aged 15-19 years; ACS data indicated unemployment was higher, and education attainment and family income were lower in

    We conducted a qualitative study of the attitudes of teens and parents toward the use of a patient portal. We conducted two teen and two parent focus groups, one teen electronic bulletin board, and one parent electronic bulletin board. Videotapes and transcripts from the groups were independently analyzed by two reviewers for significant themes, which were then validated by two other members of the research team. Twenty-eight teens and 23 parents participated in the groups. Significant themes included issues about teens' control of their own healthcare; enthusiasm about the use of a patient portal to access their providers, seek health information, and make appointments; and concerns about confidentiality. In summary, there was considerable support among teens and parents for a patient portal as well as concerns about confidentiality. The teen portal affords an opportunity to negotiate issues of confidentiality.

  5. Perceptions of Supervision Among Injured and Non-Injured Teens Working in the Retail or Service Industry.

    According to the National Institute for Occupational Safety and Health (NIOSH), a teen is injured every 9 minutes at work. Workplace supervision may affect whether teens are injured on the job. Because research on workplace supervision among teens is limited, the objectives of this study were to characterize the perceptions of supervision among injured and non-injured teen workers and assess the characteristics and perceptions of supervisors that may be associated with work-related injuries. In 2011, a cross-sectional survey was conducted among high school students. Teens who worked in retail or service industries (n= 270) were included in the sample. Non-injured teens were more likely to have reported that their supervisors cared about their safety, were helpful, listened well, and ensured that teen workers understood workplace safety. Most teens (70%) did not feel comfortable talking about safety issues with their supervisors. The importance of supervision and how supervisors are perceived in the workplace may be significant in creating a safety culture that leaves a lasting impression.

    The current study examined whether a match or mismatch between teen mothers' cultural orientation and the cultural context of the family (i.e., familial ethnic socialization) predicted mother-daughter everyday and coparenting conflict, and in turn, teen mothers' adjustment. Participants were 204 Mexican-origin teen mothers (M age = 16.81 years; SD = 1.00). Consistent with a person-environment fit perspective, findings indicated that a mismatch between teen mothers' cultural orientation (i.e., high mainstream cultural involvement) and the cultural context of the family (i.e., higher levels of familial ethnic socialization) predicted greater mother-daughter everyday conflict and coparenting conflict 1 year later. However, when there was a match (i.e., high levels of familial ethnic socialization for teen mothers with high Mexican orientation), familial ethnic socialization was not associated with mother-daughter conflict. In addition, mother-daughter conflict was positively associated with depressive symptoms and engagement in risky behaviors 1 year later among all teen mothers.

    We examined progress made by the Milwaukee community toward achieving the Milwaukee Teen Pregnancy Prevention Initiative's aggressive 2008 goal of reducing the teen birth rate to 30 live births/1000 females aged 15-17 years by 2015. We further examined differential teen birth rates in disparate racial and ethnic groups. We analyzed teen birth count data from the Wisconsin Interactive Statistics on Health system and demographic data from the US Census Bureau. We computed annual 2003-2014 teen birth rates for the city and four racial/ethnic groups within the city (white non-Hispanic, black non-Hispanic, Hispanic/Latina, Asian non-Hispanic). To compare birth rates from before (2003-2008) and after (2009-2014) goal setting, we used a single-system design to employ two time series analysis approaches, celeration line, and three standard deviation (3SD) bands. Milwaukee's teen birth rate dropped 54 % from 54.3 in 2003 to 23.7 births/1000 females in 2014, surpassing the goal of 30 births/1000 females 3 years ahead of schedule. Rate reduction following goal setting was statistically significant, as five of the six post-goal data points were located below the celeration line and points for six consecutive years (2010-2014) fell below the 3SD band. All racial/ethnic groups demonstrated significant reductions through at least one of the two time series approaches. The gap between white and both black and Hispanic/Latina teens widened. Significant reduction has occurred in the overall teen birth rate of Milwaukee. Achieving an aggressive reduction in teen births highlights the importance of collaborative community partnerships in setting and tracking public health goals.

  19. Teen motherhood in cross-cultural perspective.

    Science.gov (United States)

    Kramer, Karen L; Lancaster, Jane B

    2010-01-01

    Teen motherhood is the prevalent childbearing pattern in most traditional populations. Yet early motherhood is associated with negative biological and social outcomes in the developed world. We review the teen pregnancy literature in light of this discrepancy, emphasizing two core debates. The first debate centers on whether teens have poor pregnancy outcomes compared to older women, and whether negative outcomes are biologically based. Second, we consider the debate over the confounding effects of socio-economic conditions associated with being young. When teens are considered as a group, results are inconsistent across studies. When teens are disaggregated by age, the strongest finding across studies is that biological risk is concentrated in only the youngest of mothers. Negative consequences are associated with teen motherhood not because of chronological age per se, but because of relative developmental maturity and the availability of non-maternal support. In most traditional societies as well as in some sectors of developed societies, teen motherhood occurs within the context of extended kin networks and is subsidized through reliable economic and childcare assistance. Child-rearing practices, rather than pregnancy per se, may explain much of the discrepancy in the prevalence, success and attitudes toward teen motherhood in traditional and developed societies.

    Adolescent employment predicts lower educational engagement and achievement and greater engagement with risk behaviors. Most research has studied middle class rather than disadvantaged adolescents. We identified risk and protective behaviors associated with employment using data from a 3-wave, 12-month study of 715 low-socio-economic status female African American adolescents who were ages 15-21 at baseline. Adolescents who were employed at wave 2 (n=214) were matched with adolescents who were not employed at wave 2 (n=422) using nearest-neighbor matching on baseline factors within propensity score calipers on factors including marijuana use, sex while high, pregnancy risk, and socioeconomic status. We compared employed and non-employed teens on risk behaviors including marijuana use, sex while high or drunk, and a biomarker for semen exposure in the past 14 days. Employed teens were 44% as likely to say that their boyfriend is their primary spending money source and 43% as likely to be emotionally abused, but these benefits did not persist after employment ended. Six months after employment, employed respondents reported using marijuana 57% more often and had sex while drunk or high 2.7 times as frequently. Women who were employed at both waves 2 and 3 were 17% as likely to have their boyfriend as a primary source of spending money and 13% more likely to graduate high school, but they used marijuana twice as often, alcohol 1.6 times as often, had 1.6 times as many sexual partners, and had sex while high or drunk 2.3 times as often. Female teens who work may avoid potentially coercive romantic relationships, but they may buy drugs or alcohol with their earnings.

    Obesity disproportionately affects African American adolescents, particularly girls. While ethnically targeted marketing of unhealthful food products contributes to this disparity, it is not known how African Americans perceive the food marketing environment in their communities. Qualitative methods, specifically photovoice and group discussions, were used to understand perceptions of African American adults and teen girls regarding targeted food marketing to adolescent girls. An advisory committee of four students, two faculty, and two parents was formed, who recruited peers to photograph their environments and participate in group discussions to answer "what influences teen girls to eat what they do." Seven adults and nine teens (all female) participated in the study. Discussions were transcribed, coded, and analyzed with ATLAS.ti to identify common and disparate themes among participants. Results indicated that adults and teens perceived the type of food products, availability of foods, and price to influence the girls' choices. The girls spoke about products that were highly convenient and tasty as being particularly attractive. The adults reported that advertisements and insufficient nutrition education were also influencers. The teens discussed that the places in which food products were available influenced their choices. Results suggest that the marketing of highly available, convenient food at low prices sell products to teen girls. Future work is needed to better understand the consumer's perspective on the food and beverage marketing strategies used.

    2007-12-01

    Low test scores in science and fewer career choices in science among African American high school students than their White counterparts has resulted in lower interest during high school and an underrepresentation of African Americans in science and engineering fields. Reasons for this underachievement are not known. This qualitative study used a grounded theory methodology to examine what influence parental involvement, ethnic identity, and early mentoring had on the academic achievement in science and career choice in science of African American urban high school 10th grade students. Using semi-structured open-ended questions in individual interviews and focus groups, twenty participants responded to questions about African American urban high school student achievement in science and their career choice in science. The median age of participants was 15 years; 85% had passed either high school biology or physical science. The findings of the study revealed influences and interactions of selected factors on African American urban high school achievement in science. Sensing potential emerged as the overarching theme with six subthemes; A Taste of Knowledge, Sounds I Hear, Aromatic Barriers, What Others See, The Touch of Others, and The Sixth Sense. These themes correlate to the natural senses of the human body. A disconnect between what science is, their own individual learning and success, and what their participation in science could mean for them and the future of the larger society. Insight into appropriate intervention strategies to improve African American urban high school achievement in science was gained.

  11. Bundles of Norms About Teen Sex and Pregnancy.

    Mollborn, Stefanie; Sennott, Christie

    2015-09-01

    Teen pregnancy is a cultural battleground in struggles over morality, education, and family. At its heart are norms about teen sex, contraception, pregnancy, and abortion. Analyzing 57 interviews with college students, we found that "bundles" of related norms shaped the messages teens hear. Teens did not think their communities encouraged teen sex or pregnancy, but normative messages differed greatly, with either moral or practical rationalizations. Teens readily identified multiple norms intended to regulate teen sex, contraception, abortion, childbearing, and the sanctioning of teen parents. Beyond influencing teens' behavior, norms shaped teenagers' public portrayals and post hoc justifications of their behavior. Although norm bundles are complex to measure, participants could summarize them succinctly. These bundles and their conflicting behavioral prescriptions create space for human agency in negotiating normative pressures. The norm bundles concept has implications for teen pregnancy prevention policies and can help revitalize social norms for understanding health behaviors.

The following themes emerged: (1 Educating the Whole Child, with the subthemes: (a providing basic needs; (b academic interventions based on achievement data; (c an emphasis on reading; (d extended academic time; and (e relationships; and (2 Synergy of Expectations, with the subthemes: (a consistent student expectations; (b increased staff accountability; and (c community involvement. The researchers found that the principal by demonstrating behaviors as a change agent, a creator of vision, and a provider of necessary support and strategies, rather than adopting numerous programs, the school personnel were able to increase and sustain academic achievement of the students of poverty as well as their peers. Implications for principal practices, along with leadership preparatory programs are significant.

  13. A Cafe Scientifique for Teens

    2008-12-01

    It is well-known to those pursuing the quest to connect scientists to the public that an exceedingly hard-to- reach demographic is people of high school age. Typically, kids may tag along with their parents to museums until they reach adolescence, and then don't again appear in museums until they themselves have children. We have addressed this demographic challenge for free-choice-learning by developing a Cafe Scientifique program specifically for high school students. The Cafe Scientifique model for adults was developed in England and France, and has now spread like wildfire across the U.S. Typically, people come to a informal setting like a cafe, socialize and have food and drink, and then hear a short presentation by a scientist on a hot science topic in the news. This is followed by a period of lively discussion. We have followed this model for high school age students in four towns in northern New Mexico--Los Alamos, Santa Fe, Espanola, and Albuquerque--which represent a highly diverse demographic. We started this novel project with some trepidation, i.e. what if we build it and they don't come. But the program has proven popular beyond our expectations in all four towns. A part of the secret of success is the social setting, and-especially for this age group-the food provided. But we have also found that the kids are genuinely interested in the science topics, directing their own program, and interacting with scientists. We have often heard statements like, "I think it is important to be well-informed citizens". One of the most important aspects of the Cafes for the kids is to be able to discuss and argue about issues related to the science topic with the presenter and each other. It is an important part of the popularity that the Cafes do not involve school or parents, but also that we have strived to give the kids ownership of the program. Each town has a Youth Leadership Team-open to any teen-that discusses and prioritizes potential topics, conducts

  14. High-Stakes Testing and Student Achievement: Does Accountability Pressure Increase Student Learning?

    Directory of Open Access Journals (Sweden)

    Sharon L. Nichols

    2006-01-01

    Full Text Available This study examined the relationship between high-stakes testing pressure and student achievement across 25 states. Standardized portfolios were created for each study state. Each portfolio contained a range of documents that told the “story” of accountability implementation and impact in that state. Using the “law of comparative judgments,” over 300 graduate-level education students reviewed one pair of portfolios and made independent evaluations as to which of the two states’ portfolios reflected a greater degree of accountability pressure. Participants’ judgments yielded a matrix that was converted into a single rating system that arranged all 25 states on a continuum of accountability “pressure” from high to low. Using this accountability pressure rating we conducted a series of regression and correlation analyses. We found no relationship between earlier pressure and later cohort achievement for math at the fourth- and eighth-grade levels on the National Assessment of Educational Progress tests. Further, no relationship was found between testing pressure and reading achievement on the National Assessment of Education Progress tests at any grade level or for any ethnic student subgroup. Data do suggest, however, that a case could be made for a causal relationship between high-stakes testing pressure and subsequent achievement on the national assessment tests—but only for fourth grade, non-cohort achievement and for some ethnic subgroups. Implications and directions for future studies are discussed.

    The goal of this study was to assess achievement goal dominance, self-determined situational motivation and competence in high-level swimmers before and after three training sessions set at different working intensities (medium, sub-maximal and maximal). Nineteen athletes (males, n=9, 18.00±2.32 years; females, n=10, 16.30±2.01 years, range = 14-18) agreed to participate. They completed a questionnaire that included the Dominant Achievement Goal assessment instrument, the 2×2 Achievement Goals Questionnaire for Sport (AGQ-S), The Situational Motivation Scale (SIMS) and the Competence subscale of the Basic Psychological Needs in Exercise questionnaire (BPNES). Results indicated that participants overwhelmingly showed mastery-approach achievement goal dominance, and it remained stable at the conclusion of the different training sessions under all intensity levels. This profile was positively correlated to self-determined situational motivation and competence. However, swimmers' feelings of competence increased only after the medium intensity level training session. After the completion of the maximal intensity training session, swimmers' self-determined motivation was significantly lower compared to the other two training sessions, which could be caused by a temporary period of burnout. Results indicated that high-level swimmers had a distinct mastery-approach dominant achievement goal profile that was not affected by the workload of the different training sessions. They also showed high levels of self-determined situational motivation and competence. However, heavy workloads should be controlled because they can cause transitory burnout.

    2012-07-01

    Full Text Available The purpose of the study is to determine the relationships between locus of control (LOC orientation and high school students’ language achievement. The popular categorization of internals and externals was taken into account. The participants of this study were 121 high school students in the second, third and pre-university grades in two public high schools of Isfahan, Iran. One of the instruments used in the study was an adopted version of Julian Rotters’ locus of control (1966 which identified internal and external orientations. The participants’ English scores were regarded as the measure of their achievement. Besides, a questionnaire consisting of 29 items was administered to all 121 students. Responses were put into one way and two-way ANOVA, the regression analysis, the independent t-test, chi-square and linear regression analysis to compare the means of two sets of scores. The findings of this study show a significant relationship between locus control and achievement of high school students. The findings can be used by EFL teachers and syllabus designers.

    Dating violence is highly prevalent among adolescents. Of importance, dating violence has been associated with negative physical and mental health outcomes for teens and high-risk behaviors such as unsafe sex practices. Although a growing body of research has examined the extent and nature of this problem, little research has considered aspects of the media that might be associated with risk for teen dating violence, such as time spent using media and effects of media content. This article provides an overview of the prevalence of teen dating violence, describes the potential for assessing media use as a risk factor, offers a conceptual model, and suggests ideas for future research.

    SmithBattle, Lee I

    2013-01-01

    Teen mothers are stigmatized by stereotypes that they are unmotivated, irresponsible, and incompetent parents. In spite of the pervasiveness of these stereotypes, stigma is rarely described as a contributing factor to teen mothers' difficulties and their health and social disparities. After tracing how teen mothers have been misrepresented and stereotyped over the last half century, I describe what is known about the stigma associated with teen mothering, reasons for its persistence, efforts to reduce it, and its potentially harmful effects. Stigma should be of concern to nurses because stigmatizing practices impede effective clinical care, contribute to teen mothers' many challenges, and violate the nursing ethic that patients be treated with respect and dignity. Recommendations for restoring dignity and reducing stigma in healthcare focus on developing recognition practices that are predicated on respect and concern for the teen's well-being and her capacity as a mother. Nurses are also urged to advocate for services and policies that reduce the stigmatization and marginalization of teen mothers.

    Full Text Available This article describes a segment of a broader study of mixed cut occurs. In this space only part of the qualitative analysis is recovered around the psychosocial aspects that influence the management of the evaluation results from the application of semi-structured interviews and focus groups with 80 senior secondary schools with high and low achievement located in four states of Mexico: Sonora, Durango, Mexico City and Oaxaca. The findings are presented from categories they consider the meaning, beliefs and expectations about evaluation and how these aspects influence the actions of the directors of the schools studied. Polarized cases allow, in their contrasts, identify processes and factors that mark the differences or similarities between them. Thus it was found that school principals low achievement hope to change the attitude of teachers towards the assessment, expect supervisors to monitor teachers and external support (specialists that indicate how to evaluate them. Moreover, the idea that a school with high achievement is an organization that promotes the participation director, has high expectations of students and teachers, its management system and decision-making can achieve the objectives set, and reasserts Assessment proposes actions that seek continuous improvement.

    2007-09-15

    The mass deployment of electrolysers, within a power system serving a region of high wind resource, as the enabling mechanism for achieving five key objectives is assessed (that is: a very high installed capacity of wind power plant (WPP); zero wind curtailment during times of low demand; a very high load factor for thermal power plant; an electricity supply of low-carbon intensity; and a hydrogen supply of low-carbon intensity). Three electrolyser implementation cases were simulated for three days characterised mainly by wind availability and emphasis was placed on maximizing the smoothness of the load profile (LF) applied to thermal power plant. If zero-carbon hydrogen is to be produced a daily load factor for thermal power plant of 90% is the upper limit, but load factors of up to 100% are achievable if a carbon intensity of 3kgCO{sub 2}/kgH{sub 2} is permitted. For wind penetrations exceeding approximately 30% of system maximum demand, the electrolyser stock must include implementations close to WPP if curtailment is to be avoided. To achieve very high wind penetrations and very high load factors for thermal power plant requires a large stock of electrolysers - for the system investigated approximately 1.1 MW of electrolyser capacity is required per installed MW of wind power.

  13. Relationship of constructivist learning environment to student attitudes and achievement in high school mathematics and science

    Science.gov (United States)

    Dethlefs, Theresa Marie

    This study investigated the relationship of constructivist learning environment and standards-based teaching practices to student achievement and attitudes (self-efficacy, intrinsic value, and learning strategies) in Algebra and Biology. Further, these relationships were examined as a function of student gender and prior achievement. A purposive sample of 804 high school students enrolled in Biology I, Algebra I, or Advanced Algebra was selected for inclusion in this study. Although the dimensions of constructivist learning environment that contributed to predicting student achievement and attitudes varied by content area and criterion, the results of the present study generally provide strong support for a positive relationship between constructivist learning environment and student attitudes, but little support for a direct relationship to student achievement. Teacher reports of overall constructivist learning environment were not correlated with achievement or attitudes. Observer reports of constructivist learning environment were correlated with student intrinsic value and learning strategies. Student reports of constructivist learning environment were correlated with all three attitude measures. Multiple regression findings showed that neither overall constructivist learning environment nor standards-based teaching practices predicted achievement in any of the content areas. Overall constructivist learning environment and standards-based teaching practices were significant positive predictors of student intrinsic value and learning strategies in all three content areas, after controlling for student and classroom demographic variables. Overall constructivist learning environment and standards-based teaching practices were also significant positive predictors of self-efficacy in Algebra 1. In addition, standards-based teaching practices was a significant positive predictor of student self-efficacy in Biology. No specific dimensions of constructivist learning

    1992-12-01

    This paper describes the implementation of a community-based youth violence prevention project that utilized an educational curriculum and a mass media campaign. The extent of penetration of the intervention into target areas and the degree of contamination of control areas are assessed, and the most frequently contacted forms of educational outreach are identified. Two sources of data, provider interviews and a random digit dialed telephone survey, were used to track the source and extent of teens' exposure to the intervention. Agency provider data revealed that 40% of the 92 contacted agencies actually conducted violence prevention education, reaching 22% of the target area teens. Approximately one-half of the surveyed teens reported some exposure to the program, with 13% of the teens in target areas reporting participation in interactive educational activities associated with the project. The most common source of exposure was the media campaign. Most teens report a single exposure, usually to the media campaign, although 29% report contact with more than one form of violence prevention education. While the project did not achieve community saturation, the data show that the community-based model of intervention for violence prevention is feasible and effective in reaching teenagers. This research highlights some difficulties in evaluating prevention programs, including reconciling community ownership with project identification, the ethics of curtailing services for control purposes, and factors influencing recall of participation.

    2013-03-01

    This study aimed at assessing the impact of including children with intellectual disability (ID) in general education classrooms with support on the academic achievement of their low-, average-, and high-achieving peers without disability. A quasi-experimental study was conducted with an experimental group of 202 pupils from classrooms with an included child with mild or moderate ID, and a control group of 202 pupils from classrooms with no included children with special educational needs (matched pairs sample). The progress of these 2 groups in their academic achievement was compared over a period of 1 school year. No significant difference was found in the progress of the low-, average-, or high-achieving pupils from classrooms with or without inclusion. The results suggest that including children with ID in primary general education classrooms with support does not have a negative impact on the progress of pupils without disability.

    Previous findings have demonstrated that chronotype (morningness/intermediate/eveningness) is correlated with cognitive functions, that is, people show higher mental performance when they do a test at their preferred time of day. Empirical studies found a relationship between morningness and higher learning achievement at school and university. However, only a few of them controlled for other moderating and mediating variables. In this study, we included chronotype, gender, conscientiousness and test anxiety in a structural equation model (SEM) with grade point average (GPA) as academic achievement outcome. Participants were 158 high school students and results revealed that boys and girls differed in GPA and test anxiety significantly, with girls reporting better grades and higher test anxiety. Moreover, there was a positive correlation between conscientiousness and GPA (r = 0.17) and morningness (r = 0.29), respectively, and a negative correlation between conscientiousness and test anxiety (r = -0.22). The SEM demonstrated that gender was the strongest predictor of academic achievement. Lower test anxiety predicted higher GPA in girls but not in boys. Additionally, chronotype as moderator revealed a significant association between gender and GPA for evening types and intermediate types, while intermediate types showed a significant relationship between test anxiety and GPA. Our results suggest that gender is an essential predictor of academic achievement even stronger than low or absent test anxiety. Future studies are needed to explore how gender and chronotype act together in a longitudinal panel design and how chronotype is mediated by conscientiousness in the prediction of academic achievement.

    Highlights: • High fat diet helps in achieving peak bone mass at younger age. • Shifting from high fat to normal diet normalizes obese parameters. • Bone parameters are sustained even after withdrawal of high fat diet. - Abstract: The relationship between obesity and bone is complex. Epidemiological studies demonstrate positive as well as negative correlation between obesity and bone health. In the present study, we investigated the impact of high fat diet-induced obesity on peak bone mass. After 9 months of feeding young rats with high fat diet, we observed obesity phenotype in rats with increased body weight, fat mass, serum triglycerides and cholesterol. There were significant increases in serum total alkaline phosphatase, bone mineral density and bone mineral content. By micro-computed tomography (μ-CT), we observed a trend of better trabecular bones with respect to their microarchitecture and geometry. This indicated that high fat diet helps in achieving peak bone mass and microstructure at younger age. We subsequently shifted rats from high fat diet to normal diet for 6 months and evaluated bone/obesity parameters. It was observed that after shifting rats from high fat diet to normal diet, fat mass, serum triglycerides and cholesterol were significantly decreased. Interestingly, the gain in bone mineral density, bone mineral content and trabecular bone parameters by HFD was retained even after body weight and obesity were normalized. These results suggest that fat rich diet during growth could accelerate achievement of peak bone mass that is sustainable even after withdrawal of high fat diet.

    Hexagonal boron nitride (h-BN) detectors have demonstrated the highest thermal neutron detection efficiency to date among solid-state neutron detectors at about 51%. We report here the realization of h-BN neutron detectors possessing one order of magnitude enhancement in the detection area but maintaining an equal level of detection efficiency of previous achievement. These 3 mm × 3 mm detectors were fabricated from 50 μm thick freestanding and flexible 10B enriched h-BN (h-10BN) films, grown by metal organic chemical vapor deposition followed by mechanical separation from sapphire substrates. Mobility-lifetime results suggested that holes are the majority carriers in unintentionally doped h-BN. The detectors were tested under thermal neutron irradiation from californium-252 (252Cf) moderated by a high density polyethylene moderator. A thermal neutron detection efficiency of ˜53% was achieved at a bias voltage of 200 V. Conforming to traditional solid-state detectors, the realization of h-BN epilayers with enhanced electrical transport properties is the key to enable scaling up the device sizes. More specifically, the present results revealed that achieving an electrical resistivity of greater than 1014 Ωṡcm and a leakage current density of below 3 × 10-10 A/cm2 is needed to fabricate large area h-BN detectors and provided guidance for achieving high sensitivity solid state neutron detectors based on h-BN.

    Driving simulators can be used to evaluate driving performance under controlled, safe conditions. Teen drivers are at particular risk for motor vehicle crashes and simulated driving can provide important information on performance. We developed a new simulator protocol, the Simulated Driving Assessment (SDA), with the goal of providing a new tool for driver assessment and a common outcome measure for evaluation of training programs. As an initial effort to examine the validity of the SDA to differentiate performance according to experience, this analysis compared driving behaviors and crashes between novice teens (n=20) and experienced adults (n=17) on a high fidelity simulator for one common crash scenario, a rear-end crash. We examined headway time and crashes during a lead truck with sudden braking event in our SDA. We found that 35% of the novice teens crashed and none of the experienced adults crashed in this lead truck braking event; 50% of the teens versus 25% of the adults had a headway time headway time, 70% crashed. Among all participants with a headway time of 2-3 seconds, further investigation revealed descriptive differences in throttle position and brake pedal force when comparing teens who crashed, teens who did not crash and adults (none of whom crashed). Even with a relatively small sample, we found statistically significant differences in headway time for adults and teens, providing preliminary construct validation for our new SDA.

    There has been an ongoing debate about the inconsistent effects of heterogeneous ability grouping on students in small group work such as project-based learning. The present research investigated the roles of group heterogeneity and processes in project-based learning. At the student level, we examined the interaction effect between students' within-group achievement and group processes on their self- and collective efficacy. At the group level, we examined how group heterogeneity was associated with the average self- and collective efficacy reported by the groups. The participants were 1,921 Hong Kong secondary students in 367 project-based learning groups. Student achievement was determined by school examination marks. Group processes, self-efficacy and collective efficacy were measured by a student-report questionnaire. Hierarchical linear modelling was used to analyse the nested data. When individual students in each group were taken as the unit of analysis, results indicated an interaction effect of group processes and students' within-group achievement on the discrepancy between collective- and self-efficacy. When compared with low achievers, high achievers reported lower collective efficacy than self-efficacy when group processes were of low quality. However, both low and high achievers reported higher collective efficacy than self-efficacy when group processes were of high quality. With 367 groups taken as the unit of analysis, the results showed that group heterogeneity, group gender composition and group size were not related to the discrepancy between collective- and self-efficacy reported by the students. Group heterogeneity was not a determinant factor in students' learning efficacy. Instead, the quality of group processes played a pivotal role because both high and low achievers were able to benefit when group processes were of high quality.

    2000-07-01

    The development of a high-performance electric sports car by AC Propulsion was described along with a status report on the progress in developing the product-certified version. The development of the tzero car began in 1996. In-use testing and safety certification of prototypes is currently underway. The tzero is powered by a high-performance induction motor operated at 37 per cent higher peak current than allowed in a standard system since periods of peak power are limited to only a few seconds. The car, which can accelerate from 0 to 60 mph in 4.1 seconds, is considered to be one of the most energy-efficient cars on the road. Since the tzero will likely be sold without subsidy and since the market size for the tzero is expected to be small, in the order of 1000 units per year, it will have to be sold at a high enough price to cover the costs of small-volume production. AC Propulsion is hopeful that it may even be the first electric vehicle to be sold at a profit. Its technology and image are expected to present examples for other electric vehicles. The paper also included a comprehensive technical description of the car and its systems, such as the power electronics unit, traction converter, charger, auxiliary power supply, 12V battery, recharge interface, battery pack, battery modules and powertrain control. 4 tabs., 15 figs.

    Family processes in early life have been implicated in adolescent involvement in teen dating violence, yet the developmental pathways through which this occurs are not well understood. In this study, etiological pathways from parental psychopathology and marital conflict in infancy to involvement in dating violence in late adolescence were examined in a sample of children at high-risk due to parental alcohol problems. Families (N = 227) recruited when the child was 12 months of age were assessed at 12-, 24-, 36-months, kindergarten, 6th, 8th, and 12th grades. Slightly more than half of the children were female (51%) and the majority were of European American descent (91%). Parental psychopathology in infancy was indirectly associated with teen dating violence in late adolescence via low maternal warmth and self-regulation in early childhood, externalizing behavior from kindergarten to early adolescence, and sibling problems in middle childhood. Marital conflict was also indirectly associated with teen dating violence via child externalizing behavior. Maternal warmth and sensitivity in early childhood emerged as an important protective factor and was associated with reduced marital conflict and increased child self-regulation in the preschool years as well as increased parental monitoring in middle childhood and early adolescence. Family processes occurring in the preschool years and in middle childhood appear to be critical periods for creating conditions that contribute to dating violence risk in late adolescence. These findings underscore the need for early intervention and prevention with at-risk families.

  5. The high heritability of educational achievement reflects many genetically influenced traits, not just intelligence.

    Because educational achievement at the end of compulsory schooling represents a major tipping point in life, understanding its causes and correlates is important for individual children, their families, and society. Here we identify the general ingredients of educational achievement using a multivariate design that goes beyond intelligence to consider a wide range of predictors, such as self-efficacy, personality, and behavior problems, to assess their independent and joint contributions to educational achievement. We use a genetically sensitive design to address the question of why educational achievement is so highly heritable. We focus on the results of a United Kingdom-wide examination, the General Certificate of Secondary Education (GCSE), which is administered at the end of compulsory education at age 16. GCSE scores were obtained for 13,306 twins at age 16, whom we also assessed contemporaneously on 83 scales that were condensed to nine broad psychological domains, including intelligence, self-efficacy, personality, well-being, and behavior problems. The mean of GCSE core subjects (English, mathematics, science) is more heritable (62%) than the nine predictor domains (35-58%). Each of the domains correlates significantly with GCSE results, and these correlations are largely mediated genetically. The main finding is that, although intelligence accounts for more of the heritability of GCSE than any other single domain, the other domains collectively account for about as much GCSE heritability as intelligence. Together with intelligence, these domains account for 75% of the heritability of GCSE. We conclude that the high heritability of educational achievement reflects many genetically influenced traits, not just intelligence.

  7. Achieving high performance polymer optoelectronic devices for high efficiency, long lifetime and low fabrication cost

    Science.gov (United States)

    Huang, Jinsong

    This thesis described three types of organic optoelectronic devices: polymer light emitting diodes (PLED), polymer photovoltaic solar cell, and organic photo detector. The research in this work focuses improving their performance including device efficiency, operation lifetime simplifying fabrication process. With further understanding in PLED device physics, we come up new device operation model and improved device architecture design. This new method is closely related to understanding of the science and physics at organic/metal oxide and metal oxide/metal interface. In our new device design, both material and interface are considered in order to confine and balance all injected carriers, which has been demonstrated very be successful in increasing device efficiency. We created two world records in device efficiency: 18 lm/W for white emission fluorescence PLED, 22 lm/W for red emission phosphorescence PLED. Slow solvent drying process has been demonstrated to significantly increase device efficiency in poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl C 61-butyric acid methyl ester (PCBM) mixture polymer solar cell. From the mobility study by time of flight, the increase of efficiency can be well correlated to the improved carrier transport property due to P3HT crystallization during slow solvent drying. And it is found that, similar to PLED, balanced carrier mobility is essential in high efficient polymer solar cell. There is also a revolution in our device fabrication method. A unique device fabrication method is presented by an electronic glue based lamination process combined with interface modification as a one-step polymer solar cell fabrication process. It can completely skip the thermal evaporation process, and benefit device lifetime by several merits: no air reactive. The device obtained is metal free, semi-transparent, flexible, self-encapsulated, and comparable efficiency with that by regular method. We found the photomultiplication (PM) phenomenon in C

    Full Text Available In the age of digital technology, as teens seem to be constantly connected online, via social media, and through mobile applications, it is no surprise that they increasingly turn to digital media to answer their health questions. This study is the first of its kind to survey a large, nationally-representative sample of teens to investigate how they use the newest digital technologies, including mobile apps, social networking sites, electronic gaming and wearable devices, to explore health topics. The survey covered the types of health topics teens most frequently search for, which technologies they are most likely to use and how they use them, and whether they report having changed their behaviors due to digital health information. In addition, this survey explores how the digital divide continues to impact adolescents. Results of this study indicate that teens are concerned about many health issues, ranging from fitness, sexual activity, drugs, hygiene as well as mental health and stress. As teens virtually always have a digital device at their fingertips, it is clear that public health interventions and informational campaigns must be tailored to reflect the ways that teens currently navigate digital health information and the health challenges that concern them most.

    Thor, Craig P.; Gabler, Hampton C.

    2010-01-01

    Graduated driving licensing laws are now in place in all 50 U.S. states and the District of Columbia. However, despite stricter supervised driving requirements, restrictions on the number of passengers, and earlier nighttime driving curfews, teen drivers continue to be at a higher crash risk than the adult driving population. The National Motor Vehicle Crash Causation Survey (NMVCCS) dataset was examined to compare and contrast the primary crash factors for teen drivers (16–18 years. old) and adult drivers (35–55 years. old) in the GDL era. It is was found that teen drivers were 2.40 (CI:1.19–4.85) times more likely to be in a control loss crash and 1.88 (CI:1.12–3.15) times more likely to be in a road departure crash relative adult drivers. Furthermore, teen drivers who were in a crash were 1.73 (CI:1.25–2.38) times more likely to be distracted, 1.83 (CI: 1.38–2.43) times more likely to be driving inappropriately, and 1.47 (CI:1.30–1.67) times more likely to be inadequately aware of their driving environment than adults. Passengers and aggressive driving also contributed significantly to the heightened crash risk for teen drivers, after GDL implementation. This study emphasizes that while the number of teen crashes has decreased with GDL, the relative crash risk for certain experience related causative factors and pre-crash scenarios remain high for teen drivers after GDL implementation nationwide.

    Full Text Available The present study explored English language learning anxiety among 38 third-year high school students in English classrooms and its relationship with overall English achievement. Students’ foreign language anxiety was surveyed and analyzed using the Foreign Language Classroom Anxiety Scale (Horwitz, Horwitz, & Cope, 1986 [14] and their English achievement was measured through their final standardized English exam administered by the school. The results showed that although some students felt extremely confident and relaxed, however, one-third of the
    students experienced moderate to high-anxiety levels while learning the English language in class. Correlational analysis revealed that the total FLCAS scores had a significantly moderate negative correlation (r=-.0586, p<.01 with the total final English exams scores of the participants. Anxiety was also analyzed according to the four different variables of anxiety (communication anxiety, test anxiety, fear of negative evaluation, English classroom anxiety which were measured by the FLCAS. The results of the Pearson correlational analysis indicated that English achievement was modestly correlated with all four anxiety variables (p<0.01. Of the four types of anxiety, English Classroom anxiety had the highest correlational value. Finally, possible anxiety provoking factors
    leading to these findings are examined and discussed, and some pedagogical implications are proposed.

    Full Text Available Every student certainly demonstrates different achievement in her/his Chinese language learning process because every student has her/his own individual way to resolve their problems in learning. In learning process, student’s individual differences exist. These differences lead to different learning speed and learning style of the student. The purpose of this study was to investigate the high achievement students’ learning styles. This study was based on Reid’s learning styles theory and also uses Reid’s Perceptual Learning Style Preference Questionnaire (PLSPQ to investigate student’s learning styles. The main finding of this study is that student’s learning style preference is group style. According to student learning style preferences results, students prefer to learn together with others or in group and learn in a more interactive way.

    2014-06-01

    School engagement is an important theoretical and practical cornerstone to the promotion of academic accomplishments. This article used a tripartite-behavioral, emotional, and cognitive-model of school engagement to assess the relationship between school engagement and academic success among high school students, and to determine whether a reciprocal relationship exists between these constructs. Data were derived from 710 youth (69% female) who took part in Waves 6 through 8 (Grades 10 through 12) of the 4-H study of positive youth development. Longitudinal confirmatory factor analyses confirmed the invariance of the tripartite model of school engagement. Results of a structural equation model showed that the components of school engagement and academic achievement were mutually predictive and that these predictions varied from grade to grade. Future possibilities for evaluating the relationship between school engagement and academic achievement, as well as the implications for educational policy and practice, are discussed.

    Wright, Tiffanie L.

    The purpose of this study was to explore whether Modeling Instruction, compared to traditional lecturing, is an effective instructional method to promote academic achievement in selected high school physics classes at a rural middle Tennessee high school. This study used an ex post facto , quasi-experimental research methodology. The independent variables in this study were the instructional methods of teaching. The treatment variable was Modeling Instruction and the control variable was traditional lecture instruction. The Treatment Group consisted of participants in Physical World Concepts who received Modeling Instruction. The Control Group consisted of participants in Physical Science who received traditional lecture instruction. The dependent variable was gains scores on the Force Concepts Inventory (FCI). The participants for this study were 133 students each in both the Treatment and Control Groups (n = 266), who attended a public, high school in rural middle Tennessee. The participants were administered the Force Concepts Inventory (FCI) prior to being taught the mechanics of physics. The FCI data were entered into the computer-based Statistical Package for the Social Science (SPSS). Two independent samples t-tests were conducted to answer the research questions. There was a statistically significant difference between the treatment and control groups concerning the instructional method. Modeling Instructional methods were found to be effective in increasing the academic achievement of students in high school physics. There was no statistically significant difference between FCI gains scores for gender. Gender was found to have no effect on the academic achievement of students in high school physics classes. However, even though there was not a statistically significant difference, female students' gains scores were higher than male students' gains scores when Modeling Instructional methods of teaching were used. Based on these findings, it is recommended

    Mebane, Joyce Graham

    The purpose of this study was to examine the perceptions of West High School constituents (students, parents, teachers, administrators, and guidance counselors) about the readiness and interest of African American students at West High School to take Advanced Placement (AP) and International Baccalaureate (IB) science courses as a strategy for closing the achievement gap. This case study utilized individual interviews and questionnaires for data collection. The participants were selected biology students and their parents, teachers, administrators, and guidance counselors at West High School. The results of the study indicated that just over half the students and teachers, most parents, and all guidance counselors thought African American students were prepared to take AP science courses. Only one of the three administrators thought the students were prepared to take AP science courses. Between one-half and two-thirds of the students, parents, teachers, and administrators thought students were interested in taking an AP science course. Only two of the guidance counselors thought there was interest among the African American students in taking AP science courses. The general consensus among the constituents about the readiness and interest of African American students at West High School to take IB science courses was that it is too early in the process to really make definitive statements. West is a prospective IB school and the program is new and not yet in place. Educators at the West High School community must find reasons to expect each student to succeed. Lower expectations often translate into lower academic demands and less rigor in courses. Lower academic demands and less rigor in courses translate into less than adequate performance by students. When teachers and administrators maintain high expectations, they encourage students to aim high rather than slide by with mediocre effort (Lumsden, 1997). As a result of the study, the following suggestions should

    Science.gov (United States)

    Belen-Ferrer, Bellasanta

    2009-12-01

    This study used longitudinal data and individual, family, and academic-related matriculation variables to examine trends in initial status and growth trajectories in overall academics, mathematics, and science achievement among 224 high ability high school Asian students. Results indicate that females have an advantage in both initial status and growth rates in overall academics and science. None of the family variables entered in the models were found to be significantly related to overall academics grade point average. All available matriculation variables entered into the models explained less than or at most about half the variance in initial achievement status and growth rate in overall academics and science but not in mathematics. These results strongly imply that other factors, notably family and school and/or classroom-related variables, not measured by the ones used in the models could explain the expected variance in initial status and growth rate of the students especially in Mathematics.

  5. Hmong Parental Involvement and Support: A Comparison Between Families of High and Low Achieving High School Seniors

    Directory of Open Access Journals (Sweden)

    Katherine Green

    2009-01-01

    Full Text Available The Hmong are some of the newest refugees who have settled in the United States with population estimates around 300,000. Unfortunately research has shown many Hmong children are not as successful in their education as their peers. Parental involvement in education has consistently been shown to impact academic success and attendance in higher education programs. Little is known about Hmong parental involvement in their children’s education process. Therefore, this study was done to compare and contrast the general family characteristics, parenting methods, parental involvement philosophies, parental involvement experiences, and parental education expectations in Hmong families of high school seniors classified as either high academic achievers or low achievers. Students were classified into either higher or lower academic achievement groups based on their high school cumulative GPA. Five students were randomly selected for each group and a qualitative research interview method was used to interview the students and both of their parents (n=30. The findings showed the parents of the higher academic achieving students were younger, had higher levels of education, and had better relationships and trust with the students. Parents from both groups did not have any written rules for their children to follow at home, they mainly became involved in their children’s education during the elementary and middle school years, and they did not have any specific preference of an educational level, career, or school for their children after high school. Recommendations for ways Hmong families can be encouraged to participate more in education are made.

  16. Subpixel shift with Fourier transform to achieve efficient and high-quality image interpolation

    Science.gov (United States)

    Chen, Qin-Sheng; Weinhous, Martin S.

    1999-05-01

    A new approach to image interpolation is proposed. Different from the conventional scheme, the interpolation of a digital image is achieved with a sub-unity coordinate shift technique. In the approach, the original image is first shifted by sub-unity distances matching the locations where the image values need to be restored. The original and the shifted images are then interspersed together, yielding an interpolated image. High quality sub-unity image shift which is crucial to the approach is accomplished by implementing the shift theorem of Fourier transformation. It is well known that under the Nyquist sampling criterion, the most accurate image interpolation can be achieved with the interpolating function (sinc function). A major drawback is its computation efficiency. The present approach can achieve an interpolation quality as good as that with the sinc function since the sub-unity shift in Fourier domain is equivalent to shifting the sinc function in spatial domain, while the efficiency, thanks to the fast Fourier transform, is very much improved. In comparison to the conventional interpolation techniques such as linear or cubic B-spline interpolation, the interpolation accuracy is significantly enhanced. In order to compensate for the under-sampling effects in the interpolation of 3D medical images owing to a larger inter-slice distance, proper window functions were recommended. The application of the approach to 2- and 3-D CT and MRI images produced satisfactory interpolation results.

    The phenomenon of logical stochastic resonance (LSR) in a nonlinear bistable system is demonstrated by numerical simulations and experiments. However, the bit rates of the logical signals are relatively low and not suitable for practical applications. First, we examine the responses of the bistable system with fixed parameters to different bit rate logic input signals, showing that an arbitrary high bit rate LSR in a bistable system cannot be achieved. Then, a normalized transform of the LSR bistable system is introduced through a kind of variable substitution. Based on the transform, it is found that LSR for arbitrary high bit rate logic signals in a bistable system can be achieved by adjusting the parameters of the system, setting bias value and amplifying the amplitudes of logic input signals and noise properly. Finally, the desired OR and AND logic outputs to high bit rate logic inputs in a bistable system are obtained by numerical simulations. The study might provide higher feasibility of LSR in practical engineering applications. Project supported by the National Natural Science Foundation of China (Grant No. 51379526).

    Achievement of sustainability in metal life cycles from mining of virgin ore to consumer and industrial devices to end-of-life products requires greatly increased recycling rates and improved processing of metals using conventional and green chemistry technologies. Electronic and other high-tech products containing precious, toxic, and specialty metals usually have short lifetimes and low recycling rates. Products containing these metals generally are incinerated, discarded as waste in landfills, or dismantled in informal recycling using crude and environmentally irresponsible procedures. Low recycling rates of metals coupled with increasing demand for high-tech products containing them necessitate increased mining with attendant environmental, health, energy, water, and carbon-footprint consequences. In this tutorial review, challenges to achieving metal sustainability, including projected use of urban mining, in present high-tech society are presented; health, environmental, and economic incentives for various government, industry, and public stakeholders to improve metal sustainability are discussed; a case for technical improvements, including use of molecular recognition, in selective metal separation technology, especially for metal recovery from dilute feed stocks is given; and global consequences of continuing on the present path are examined.

  19. The C-2000 program : achieving high performance through better technologies and changes in the design process

    In 1993, CANMET Energy Technology Centre of Natural Resources Canada launched a demonstration program for high-performance buildings. The focus of the C-2000 Program for Advanced Commercial Buildings was on energy and environmental performance, but it also included a variety of other parameters. Of the 13 buildings that have been designed, some have been built while others are approaching the construction phase. The Canadian Model National Energy Code for Buildings (MNECB) is the standard used as a performance benchmark. The demonstration program has shown that the likelihood of high performance depends on close teamwork by all members of a building design team with the augmentation of a normal design team with an energy engineer, an environmental specialist and a cost consultant. Other factors which help achiever high performance are the use of clear and comprehensive technical guidelines and the development of short written performance strategies. The commissioning of all major systems during the construction phase also help ensure that the systems are properly installed and perform to design levels. The completed projects have confirmed that a 35 to 50 per cent improvement in energy performance levels can be achieved with only modest increases in design budgets. 7 refs., 7 figs.

    Charge balance in organic light emitting structures is essential to simultaneously achieving high brightness and high efficiency. In DC-driven organic light emitting devices (OLEDs), this is relatively straight forward. However, in the newly emerging, capacitive, field-activated AC-driven organic devices, charge balance can be a challenge. In this work we introduce the concept of gating the compensation charge in AC-driven organic devices and demonstrate that this can result in exceptional increases in device performance. To do this we replace the insulator layer in a typical field-activated organic light emitting device with a nanostructured, wide band gap semiconductor layer. This layer acts as a gate between the emitter layer and the voltage contact. Time resolved device characterization shows that, at high-frequencies (over 40 kHz), the semiconductor layer allows for charge accumulation in the forward bias, light generating part of the AC cycle and charge compensation in the negative, quiescent part of the AC cycle. Such gated AC organic devices can achieve a non-output coupled luminance of 25,900 cd/m(2) with power efficiencies that exceed both the insulator-based AC devices and OLEDs using the same emitters. This work clearly demonstrates that by realizing balanced management of charge, AC-driven organic light emitting devices may well be able to rival today's OLEDs in performance.

    The dissertation presents two analytic approaches, a variable-centered and person-centered approach, to investigating holistic patterns of the cognitive, motivational, and affective correlates of science achievement and engagement in a sample of 491 10th and 11th grade high-school students. Building on Snow's (1989) idea of two pathways to achievement outcomes, Study 1 adopted a variable-centered approach to examining how cognitive and motivational factors associated with the performance and commitment pathways, respectively, contributed to the prediction of achievement outcomes in science. Results of hierarchical regression analyses showed that (a) students' cognitive abilities were the strongest predictors of their performance in science as measured by standardized test scores; (b) motivational processes enhanced the predictive validity for science test scores and grades beyond the variance accounted for by ability and demography; (c) motivational processes were the strongest predictors of students' commitment to science in the form of situational engagement and anticipated choices of science-related college majors and careers; and (d) competence beliefs served as a point of contact between the performance and commitment pathways. These results are consistent with Snow's (1989) conjecture that both performance and commitment pathway-related factors are necessary for understanding the full range of person-level inputs to achievement outcomes. Study 2 adopted a person-centered approach to examining holistic organizations of psychological factors within individuals and their relations to science achievement and engagement. Four types of students characterized by unique configurations of cognitive, motivational, and affective attributes were identified in both the male and female subsamples using inverse factor analysis. Type membership was found to distinguish students in various indicators of science achievement and engagement. Two of the four types were also found

    High levels of youth employment, workplace hazards, and characteristics unique to adolescents contribute to a relatively high incidence of injuries among teens in the restaurant industry. This article discusses the ProSafety model of injury prevention among teen restaurant workers. Through integration with an existing career and technical education program, the ProSafety project seeks to prevent occupational injuries among the teen worker population through classroom safety education and internship skills reinforcement. ProSafety is the product of an innovative collaboration with occupational health nurses, business professionals, educators, and government. Its approach is derived from Social Cognitive Theory, is consistent with key values and strategies of occupational health nurses, and provides lessons for practitioners seeking to reduce occupational injuries in food service or among other populations of adolescent workers.

    BACKGROUND/CONTEXT: Brown v Board of Education fundamentally changed our nation's schools, yet we know surprisingly little about how and whether they provide equality of educational opportunity. Although substantial evidence suggests that African American and Latino students who attend these schools face fewer learning opportunities than their White counterparts, until now, it has been impossible to examine this using a representative sample because of lack of data. PURPOSE/OBJECTIVE/RESEARCH QUESTION/FOCUS OF STUDY: This study uses newly available data to investigate whether racially diverse high schools offer equality of educational opportunity to students from different racial and ethnic groups. This is examined by measuring the relative representation of minority students in advanced math classes at the beginning of high school and estimating whether and how this opportunity structure limits the level of achievement attained by African American and Latino students by the end of high school. SETTING: This study uses data from the Adolescent Health and Academic Achievement Study (AHAA) and its partner study, the National Longitudinal Study of Adolescent Health (Add Health), a stratified, nationally representative study of students in U.S. high schools first surveyed in 1994-1995. POPULATION/PARTICIPANTS/SUBJECTS: Two samples of racially diverse high schools were used in the analysis: one with African Americans, Whites, and Asians (26 schools with 3,149 students), and the other with Latinos, Whites, and Asians (22 schools with 2,775 students). RESEARCH DESIGN: Quantitative analyses first assess how high schools vary in the extent to which minority students are underrepresented in advanced sophomore math classes. Hierarchical multilevel modeling is then used to estimate whether racial-ethnic differences in representation in advanced math have an impact on African American and Latino students' achievement by the end of high school, relative to the Whites and Asians

    Parvovirus retentive filters that assure removal of viruses and virus-like particles during the production of therapeutic proteins significantly contribute to total manufacturing costs. Operational approaches that can increase throughput and reduce filtration area would result in a significant cost savings. A combination of methods was used to achieve high throughputs of an antibody or therapeutic protein solution through three parvovirus retentive filters. These methods included evaluation of diatomaceous earth or size-based prefilters, the addition of additives, and the optimization of protein concentration, temperature, buffer composition, and solution pH. An optimum temperature of 35°C was found for maximizing throughput through the Virosart CPV and Viresolve Pro filters. Mass-throughput values of 7.3, 26.4, and 76.2 kg/m(2) were achieved through the Asahi Planova 20N, Virosart CPV, and Viresolve Pro filters, respectively, in 4 h of processing. Mass-throughput values of 73, 137, and 192 kg/m(2) were achieved through a Millipore Viresolve Pro filter in 4.0, 8.8, and 22.1 h of processing, respectively, during a single experiment. However, large-scale parvovirus filtration operations are typically controlled to limit volumetric throughput to below the level achieved during small-scale virus spiking experiments. The virus spike may cause significant filter plugging, limiting throughput. Therefore newer parvovirus filter spiking strategies should be adopted that may lead to more representative viral clearance data and higher utilization of large-scale filter capacity.

    The purpose of this pilot study was to test the safety, acceptability, feasibility, and effectiveness of Moms Growing Together (MGT), an intervention to prevent and reduce psychological distress in teen mothers. A mixed method design was used. The primary outcomes were reported satisfaction with MGT (acceptance); successful recruitment and retention of teen mothers (feasibility); and prevention or reduction of psychological distress (safety and effectiveness). Summary scores on each of three symptom measures operationally defined psychological distress. Sixteen African-American teen mothers participated in the study: eight in MGT and eight in a comparison group. MGT was considered safe and acceptable. MGT had a negative small effect (effect size [ES] = -0.028) on decreasing depression in participants and a moderate effect in reducing anxiety (ES = 0.395) and trauma symptoms (ES = 0.521-0.554) relative to the comparison group. Prolonged recruitment limited feasibility. Because psychological distress casts a long shadow on teen mothers' well-being, developing teen-friendly clinical programs that address their mental health is a high priority. © 2017 Wiley Periodicals, Inc.

    To test the specificity of the association between cigarette advertising and adolescent smoking initiation. A longitudinal survey of 2102 adolescents, aged 10 to 17 years at baseline, who never smoked was conducted by using masked images of 6 cigarette advertisements and 8 other commercial products with all brand information digitally removed. The exposure variable was a combination of contact frequency and cued recall of brands for cigarette and other advertisements. Multilevel mixed-effects Poisson regressions were used to assess smoking initiation 9 months after the baseline assessment as a function of cigarette-advertisement exposure, other advertisement exposure, and baseline covariates. Thirteen percent (n = 277) of students initiated smoking during the observation period. Although the incidence of trying smoking was associated with increased exposure to cigarette advertisements (10% in the low, 12% in the medium, and 19% in the high cigarette-advertisement exposure tertile initiated smoking), exposure to other advertisements did not predict smoking initiation. Compared with low exposure to cigarette advertisements, high exposure remained a significant predictor of adolescent smoking initiation after controlling for baseline covariates (adjusted relative risk: 1.46 [95% confidence interval: 1.08-1.97]; P marketing and teen smoking; exposure to cigarette advertisements, but not other advertisements, is associated with smoking initiation.

    Full Text Available Abstract Background Response rates in surveys have been falling over the last 20 years, leading to the need for novel approaches to enhance recruitment. This study describes strategies used to maximise recruitment to a home interview survey of mothers with young children living in areas of high deprivation. Methods Mothers of two year old children received a letter from their GP inviting them to take part in a survey on diet. Participants were subsequently recruited by a researcher. The researcher first tried to contact potential participants by telephone, to discuss the study and make an appointment to conduct a home interview. Where telephone numbers for women could not be obtained from GP records, web searches of publicly available databases were conducted. After obtaining correct telephone numbers, up to six attempts were made to establish contact by telephone. If this was unsuccessful, a postal request for telephone contact was made. Where no telephone contact was achieved, the researcher sent up to two appointments by post to conduct a home interview. Results Participating GPs invited 372 women to take part in a home based interview study. GP practices provided telephone numbers for 162 women, of which 134 were valid numbers. The researcher identified a further 187 numbers from electronic directories. Further searches of GP records by practice staff yielded another 38 telephone numbers. Thus, telephone numbers were obtained for 99% of potential participants. The recruitment rate from telephone contacts was 77%. Most of the gain was achieved within four calls. For the remaining women, contact by post and home visits resulted in 18 further interviews, corresponding to 35% of the women not recruited by telephone. The final interview rate was 82%. This was possible because personal contact was established with 95% of potential participants. Conclusion This study achieved a high response rate in a hard to reach group. This was mainly achieved

  17. High Titer and Yields Achieved with Novel, Low-Severity Pretreatment Strategy

    Energy Technology Data Exchange (ETDEWEB)

    2016-03-01

    NREL researchers obtained high concentration sugar syrups in enzymatic hydrolysis that are fermentable to ethanol and other advanced biofuels and intermediate products at high yields. The novel DMR process is simpler and bypasses all severe pretreatment methods, thus reducing the environmental impact. The results are unprecedented. Researchers achieved a high concentration of sugars (230g/L of monomeric sugar and 270 g/L total sugar) and this low toxicity, highly fermentable syrup yielded 86 g/L ethanol (> 90 percent conversion). In addition, the lignin streams from this process can readily be converted to jet or renewable diesel blendstocks through a hydrodeoxygenation step. The NREL-developed, low severity DMR process may potentially replace higher severity chemical pretreatments and associated expensive reactors constructed of exotic alloys with a simpler process, using commercial-scale equipment commonly associated with the pulp and paper industry, to produce high concentration, low toxicity sugar streams and highly reactive lignin streams from non-food renewable biomass for biological and catalytic upgrading to advanced biofuels and chemicals. The simpler DMR process with black liquor recycling could reduce environmental and life-cycle impacts, and repurpose shuttered pulp and paper mills to help revitalize rural economies.

    Achieving a high growth rate is paramount for making large-area transparent conducting oxide coatings at a low cost. Unfortunately, the quality of thin films grown by most techniques degrades as the growth rate increases. Filtered dc cathodic arc is a lesser known technique which produces a stream of highly ionized plasma, in stark contrast to the neutral atoms produced by standard sputter sources. Ions bring a large amount of potential energy to the growing surface which is in the form of heat, not momentum. By minimizing the distance from cathode to substrate, the high ion flux gives a very high effective growth temperature near the film surface without causing damage from bombardment. The high surface temperature is a direct consequence of the high growth rate and allows for high-quality crystal growth. Using this technique, 500-1300 nm thick and highly transparent ZnO : Al films were grown on glass at rates exceeding 250 nm min{sup -1} while maintaining resistivity below 5 x 10{sup -4} {Omega} cm with electron mobility as high as 60 cm{sup 2} V{sup -1} s{sup -1}.

    2013-01-01

    Full Text Available A thorough analysis of electric field is carried out so as to verify that a novel dual-electrode plug can build intensive electric field and can improve the main drawbacks of feeble electric field and low ignition efficiency of the traditional plug. With intensive electric field, the proposed novel plug can achieve high performance ignition, resulting in fuel saving and exhaust reduction. Gauss law is applied for electric field analysis to show that intensive electric field can be built by the novel plug. Then, according to Faraday law a lower-voltage ignition feature accomplished by the plug is discussed. Compared with traditional plug, the novel dual-electrode plug has the following advantages. (1 Much higher energy density is built between the plug electrodes, lowering ignition voltage requirement. (2 Electromagnetic interference (EMI problem caused by high ignition voltage is readily resolved. (3 Ignition time delay can be improved. (4 The feature to save fuel consuming is achieved. (5 The exhaust of CO and HC is reduced significantly. Practical measurements are fulfilled to validate the electric field analysis and to demonstrate the features of the proposed dual-electrode plug.

    Full Text Available This paper reviews the changing strategies for both process and outcome evaluations of teen pregnancy prevention programs over the past few decades. Implementation evaluations have emphasized discovery of what program attributes are most effective in reducing teen pregnancy and its antecedents. Outcome evaluations have moved from collecting data to measure knowledge, attitudes, and program satisfaction to measuring behavior change including postponement of sexual involvement, increased used of contraception, or reduction in teen pregnancy. High quality randomized control trials or quasi-experimental designs are being increasingly emphasized, as are sophisticated analysis techniques using multi-variate analyses, controls for cluster sampling, and other strategies designed to build a more solid knowledge base about how to prevent early pregnancy.

    Low-income teenagers are more likely to lack health insurance than younger children. Using data from the 2006, 2007, and 2008 rounds of the National Health Interview Survey, we examine whether differences between teens and younger children in socioeconomic factors, public health insurance eligibility, and observable family characteristics explain this apparent age-related coverage gap. Somewhat surprisingly, they do not. We find a highly robust age-coverage gradient among poor and near-poor children. Our results suggest the need to examine teen-specific insurance enrollment dynamics, particularly in families with no younger siblings, to optimize the effect of the newly enacted Patient Protection and Affordable Care Act on teens' insurance coverage.

    This paper describes the theoretical foundation, development, and feasibility testing of an online, evidence-based intervention for teen dating violence prevention designed for dissemination. Teen Choices: A Program for Healthy, Non-Violent Relationships relies on the Transtheoretical Model of Behavior Change and expert system technology to deliver assessments and feedback matched to stage of change for using healthy relationship skills. The program also tailors feedback to dating status, risk level, and other key characteristics. Ninety-nine students from high schools in Tennessee and Rhode Island completed a Teen Choices session and 97 completed an 11-item acceptability evaluation. 100% of participants completed the intervention session as intended. Evaluations of the program were favorable. For example, 88.7% agreed the program feedback was easy to understand, and 86.7% agreed that the program could help people develop healthier relationships. Findings provide encouraging evidence of the acceptability and feasibility of this approach to dating violence prevention.

    Full Text Available The article deals with the communicative competence formation of young adolescents in the secondary school at the Russian language lessons. The author maintains that the key element of the above problem is the vocabulary development guaranteeing both comprehension and verbal expression formation – oral and written. The theoretical part of the research explores different word functions: nominal, communicative, text generating and semantic. The correlation between the mental development level and lexical semantic system formation is emphasized. The age specific features of junior teens are listed: rising interest to various life spheres and activi- ties, capability of formulating opinions and judgments, self-awareness, formation of values. The relationship complexity stimulates vocabulary development of 10 to 12 year-old children; however, the process requires peda- gogical facilitation.The monitoring of speech development proves the necessity of commutative competence formation of the fifth- and sixth-year pupils.

    Full Text Available The article deals with the communicative competence formation of young adolescents in the secondary school at the Russian language lessons. The author maintains that the key element of the above problem is the vocabulary development guaranteeing both comprehension and verbal expression formation – oral and written. The theoretical part of the research explores different word functions: nominal, communicative, text generating and semantic. The correlation between the mental development level and lexical semantic system formation is emphasized. The age specific features of junior teens are listed: rising interest to various life spheres and activi- ties, capability of formulating opinions and judgments, self-awareness, formation of values. The relationship complexity stimulates vocabulary development of 10 to 12 year-old children; however, the process requires peda- gogical facilitation.The monitoring of speech development proves the necessity of commutative competence formation of the fifth- and sixth-year pupils. The paper presents the model of communicative competence development and its approbation results received for the junior adolescents.

    Work experience has been a feature of the secondary school curriculum in the United Kingdom for a number of years. Usually requested by the pupil, it aims to provide opportunities for school pupils to enhance their knowledge and understanding of an occupation. The main benefits are claimed to be that it can help pupils develop an insight into the skills and attitudes required for an occupation and an awareness of career opportunities. However the quality and choice of placements are considered to be of great importance in this process and in influencing career choice [Department for Education and Skills (DfES), 2002a. Work Experience: A Guide for Employers. Department for Education and Skills, London]. As university departments of nursing experience a decline in the number of school pupils entering student nurse education programmes, and with the competition for school leavers becoming even greater, it is important to consider whether school pupils have access to appropriate work placements in nursing and what influence their experience has on pursuing nursing as a career choice. This paper is based on interview data from 20 high academic achieving fifth and sixth year school pupils in Scotland, paradigmatic cases from a larger survey sample (n=1062), who had considered nursing as a possible career choice within their career preference cluster, but then later disregarded nursing and decided to pursue medicine or another health care profession. This was partly reported by Neilson and Lauder [Neilson, G.R., Lauder, W., 2008. What do high academic achieving school pupils really think about a career in nursing: analysis of the narrative from paradigmatic case interviews. Nurse Education Today 28(6), 680-690] which examined what high academic achieving school pupils really thought about a career in nursing. However, the data was particularly striking in revealing the poor quality of nursing work experience for the pupils, and also their proposal that there was a need

    BACKGROUND. Theories distinguish between student-initiated and teacher-initiated regulation of students' learning activities, or between strong, shared, or loose teacher control during the completion of learning tasks. Empirical validations for such distinctions are scarce, however. AIM. The present study aimed at (a) investigating students' perceptions of control behaviours exhibited by their English teachers; and (b) exploring the contribution of different types of teacher control behaviours to students' cognitive outcomes (English Achievement). SAMPLE. The sample comprised 732 English as a Foreign Language (EFL) students studying in three major fields of high school (Mathematics, Natural Science, and Humanities). The participants (16-17 years of age) were selected from third-grade classes of 27 EFL teachers working in 25 high schools of 6 main different geographical regions in the Isfahan province, Iran. METHOD. To obtain a comprehensive picture of different control types exhibited by Iranian EFL teachers, the control subscales of the two existing questionnaires, i.e., the Questionnaire on Instructional Behaviours (QIB), adapted by Den Brok et al. (2004) and the Questionnaire on Lesson Activities (QLA) used by Den Brok (2001) were merged to form the Questionnaire of Teacher Control (QTC). The development of this Persian instrument involved several steps: translation and back translation by the researchers, one expert translator, and two EFL teachers; piloting; and a final administration of the questionnaire to the student sample. With respect to the second aim of the study, data regarding students' performances on the Standardized National English Achievement Tests were gathered from local educational offices and schools. RESULTS AND CONCLUSION. Statistical analyses supported acceptable reliability and validity of the instrument. A main factor structure with three types of teacher control (strong/high, shared/mid, and loose/low) was found to underlie students

    Love wave sensors have been widely used for sensing applications. In this work, we introduce the theoretical analysis of the monolayer and double-layer waveguide Love wave sensors. The velocity, particle displacement and energy distribution of Love waves were analyzed. Using the variations of the energy repartition, the sensitivity coefficients of Love wave sensors were calculated. To achieve a higher sensitivity coefficient, a thin gold layer was added as the second waveguide on top of the silicon dioxide (SiO₂) waveguide-based, 36 degree-rotated, Y-cut, X-propagating lithium tantalate (36° YX LiTaO₃) Love wave sensor. The Love wave velocity was significantly reduced by the added gold layer, and the flow of wave energy into the waveguide layer from the substrate was enhanced. By using the double-layer structure, almost a 72-fold enhancement in the sensitivity coefficient was achieved compared to the monolayer structure. Additionally, the thickness of the SiO₂ layer was also reduced with the application of the gold layer, resulting in easier device fabrication. This study allows for the possibility of designing and realizing robust Love wave sensors with high sensitivity and a low limit of detection.

    Asthma is the most frequent reason for absence from school; it accounts for one-third of all days of missed instruction, placing students at risk for academic failure and social isolation. This study compared high school students with asthma with those without asthma, and examined the relationship of their attitudes toward school health services, absenteeism, academic achievement, and the supposition that school nurse services play an essential part in the academic process. Surveys were completed by all students who participated in the study. Twenty-eight students with asthma reported levels of illness and school nurse support in an additional survey. Data revealed that students with asthma were absent more frequently, scored lower in mathematics, and participated less in school activities than their peers without asthma. Their level of illness did not predict the number of days absent, which was negatively correlated with achievement and positively correlated with students' permissive attitudes toward absenteeism. Findings indicate that school nurse interventions were sources of physical, social, emotional, and academic support.

    Adolescents work in varied environments and are exposed to hazards. Parents of these working adolescents have an opportunity to help them select jobs and address worker safety issues with employers. The present study conducted telephonic interviews among a national sample of 922 working adolescents along with one parent of each to examine the involvement of parents in their children's employment and safety issues. Over 70% of parents were found who helped their children identify job opportunities, consider questions about work hours or tasks, fill out job applications, prepare for interviews, or handle difficult safety issues. Parents suggested stronger actions in response to hypothetical situations than when confronted with real problems. Mean level of parental involvement did not vary by the number of hazards reported by teen workers. Parents were involved in helping their teens with work. Further research should explore how to enhance parental effectiveness by making work safe for teens.

    How do we advance the environmental literacy of young people, support the next generation of environmental stewards and increase the diversity of the leadership of zoos and aquariums? We believe it is through ongoing evaluation of zoo and aquarium teen programming and have founded a consortium to pursue those goals. The Zoo and Aquarium Teen Program Assessment Consortium (ZATPAC) is an initiative by six of the nation's leading zoos and aquariums to strengthen institutional evaluation capacity, model a collaborative approach toward assessing the impact of youth programs, and bring additional rigor to evaluation efforts within the field of informal science education. Since its beginning in 2004, ZATPAC has researched, developed, pilot-tested and implemented a pre-post program survey instrument designed to assess teens' knowledge of environmental issues, skills and abilities to take conservation actions, self-efficacy in environmental actions, and engagement in environmentally responsible behaviors. Findings from this survey indicate that teens who join zoo/aquarium programs are already actively engaged in many conservation behaviors. After participating in the programs, teens showed a statistically significant increase in their reported knowledge of conservation and environmental issues and their abilities to research, explain, and find resources to take action on conservation issues of personal concern. Teens also showed statistically significant increases pre-program to post-program for various conservation behaviors, including "I talk with my family and/or friends about things they can do to help the animals or the environment," "I save water...," "I save energy...," "When I am shopping I look for recycled products," and "I help with projects that restore wildlife habitat."

    Drawing on in-depth interview data collected on 18 high-achieving Chinese American students, the authors examine domains of acculturation-based conflicts, parent and child internal conflicts, and conflict resolution in their families. Their analyses show that well-established negative communication patterns in educational expectations, divergent attitudes toward other races and country of origin, and cultural and language barriers contributed to parent-child conflicts. Their findings also illustrate important internal conflicts both adolescents and parents had along the cultural tightrope of autonomy and relatedness. Finally, the vertical in-group conflict resolution style that was evidenced in youths' accounts raises questions about cultural differences in constructive versus destructive conflict resolution styles. © 2012 Wiley Periodicals, Inc., A Wiley Company.

    Full Text Available Learners form their self-efficacy beliefs by interpreting information primarily from four sources namely performance accomplishments, vicarious experiences, verbal persuasion, and emotional arousal. It is important to recognize the four cognitive nature of self-efficacy because the cognitive appraisal of information from the four sources will influence self-efficacy and it cannot be evaluated based on one source per se (Lane, Jones & Stevens 2002. This article explores the four sources of self-efficacy among the high achievers in writing course. In analysing the finding, Z-scores were derived from each self-efficacy component score based on the aggregate mean and the standard deviation of the class. Findings show high frequency of negative z-value reported for Specific Progress (SPR and Social Feedback (SF. Meanwhile, high frequency of positive z-value is found in the General Progress (GPR and Physiological States (PS components. Based on the finding, pedagogical implications, limitations and directions for further research are presented.
