    2013-01-01

    Background Tailored psychosocial activity-based interventions have been shown to improve mood, behaviour and quality of life for nursing home residents. Occupational therapist delivered activity programs have shown benefits when delivered in home care settings for people with dementia. The primary aim of this study is to evaluate the effect of LEAP (Lifestyle Engagement Activity Program) for Life, a training and practice change program on the engagement of home care clients by care workers. Secondary aims are to evaluate the impact of the program on changes in client mood and behaviour. Methods/design The 12 month LEAP program has three components: 1) engaging site management and care staff in the program; 2) employing a LEAP champion one day a week to support program activities; 3) delivering an evidence-based training program to care staff. Specifically, case managers will be trained and supported to set meaningful social or recreational goals with clients and incorporate these into care plans. Care workers will be trained in and encouraged to practise good communication, promote client independence and choice, and tailor meaningful activities using Montessori principles, reminiscence, music, physical activity and play. LEAP Champions will be given information about theories of organisational change and trained in interpersonal skills required for their role. LEAP will be evaluated in five home care sites including two that service ethnic minority groups. A quasi experimental design will be used with evaluation data collected four times: 6-months prior to program commencement; at the start of the program; and then after 6 and 12 months. Mixed effect models will enable comparison of change in outcomes for the periods before and during the program. The primary outcome measure is client engagement. Secondary outcomes for clients are satisfaction with care, dysphoria/depression, loneliness, apathy and agitation; and work satisfaction for care workers. A process

    To evaluate the impact of LEAP, a volunteer-based, inpatient asthma education program for families of inner-city children with asthma. 711 children ages 2-17 years admitted with status asthmaticus were randomized to receive usual care or usual care plus a supplemental education intervention. Both groups completed a baseline interview. Trained volunteer lay educators conducted individualized bedside education with the intervention group. Primary outcome was attendance at a post-hospitalization follow-up visit 7-10 days after discharge. Secondary outcomes included parent-reported asthma management behaviors, symptoms, and self-efficacy scores from a one month follow-up interview. Post-hospitalization asthma clinic attendance was poor (38%), with no difference between groups. Families randomized to the intervention group were more likely to report use of a controller (OR 2.4, 95% CI 1.3-4.2, peducation by trained lay volunteers was associated with improved asthma management behaviors. This novel volunteer-based program could have widespread implications as a sustainable model for asthma education. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    The Lifestyle Engagement Activity Program (LEAP) incorporates social support and recreational activities into case-managed home care. This study's aim was to evaluate the effect of LEAP on engagement, mood, and behavior of home care clients, and on case managers and care workers. Quasi-experimental. Five Australian aged home care providers, including 2 specializing in care for ethnic minorities. Clients (n = 189) from 5 home care providers participated. The 12-month program had 3 components: (1) engaging support of management and staff; (2) a champion to drive practice change; (3) staff training. Case managers were trained to set meaningful social and/or recreational goals during care planning. Care workers were trained in good communication, to promote client independence and choice, and in techniques such as Montessori activities, reminiscence, music, physical activity, and humor. Data were collected 6 months before program commencement, at baseline, and 6 and 12 months. The Homecare Measure of Engagement Staff report and Client-Family interview were primary outcomes. Secondary outcomes were the Cohen-Mansfield Agitation Inventory; apathy, dysphoria, and agitation subscales of the Neuropsychiatric Inventory-Clinician Rating; the geriatric depression scale; UCLA loneliness scale; and home care satisfaction scale. Staff provided information on confidence in engaging clients and the Utrecht Work Engagement Scale. Twelve months after program commencement, clients showed a significant increase in self- or family-reported client engagement (b = 5.39, t[113.09] = 3.93, P recreationally engage clients (b = 0.52, t(21.33) = 2.80, P = .011, b = 0.29, t(198.69) = 2.58, P = .011, respectively). There were no significant changes in care worker-rated client engagement or client or family self-complete measures of depression or loneliness (P > .05). Client and family self-rated apathy increased over 12 months (b = 0.04, t(43.36) = 3.06, P = .004; b = 3.63, t(34.70) = 2.20, P

    1998-01-01

    Healthy Start is a 3-year demonstration and education research project designed to evaluate the effectiveness of a multidimensional cardiovascular (CV) risk reduction intervention in preschool centers over a 3-year period of time. Two primary interventions are employed. The first is the preschool food service intervention program designed to reduce the total fat in preschool meals and snacks to less than 30% of calories and reduce the saturated fat to less than 10% of calories. The second major intervention is a comprehensive preschool health education curriculum, focused heavily on nutrition. Effectiveness of the intervention will be determined through evaluation of changes in dietary intake of preschool children at school meals and snacks, especially with respect to intake of total and saturated fat. Evaluation of the education component will include assessment of program implementation by teachers, assessment of changes in nutrition knowledge by preschool children, and assessment of changes in home meals that children consume (total and saturated fat content). Blood cholesterol will be evaluated semiannually to evaluate changes that may be due to modification of dietary intake. Growth and body fatness will also be assessed. While substantial efforts have targeted CV risk reduction and health education for elementary school children, similar efforts aimed at preschool children have been lacking. The rationale for beginning CV risk reduction programs for preschool children is based upon the premise that risk factors for heart disease are prevalent by 3 years of age and tend to track over time, most commonly hypercholesterolemia and obesity, both related to nutrition. Since the behavioral antecedents for nutritional risk factors begin to be established very early in life, it is important to develop and evaluate new educational initiatives such as Healthy Start, aimed at the primary prevention of cardiovascular risk factors in preschool children. The purpose of this

    Full Text Available Participation of at least 95% of children between the ages of 4 and the mandatory school age in high-quality preschool programs represents an important contribution to the achievement of the Europe 2020 strategy. Slovenia is not far from achieving this objective; however, if we consider participation in preschool programs from the perspective of the entire population of preschool children and the realisation of children’s rights, we note that nearly a quarter of children - among them (at least in the wider European area the most disadvantaged - have not realised the right to education. We studied the awareness of the importance of ensuring access to preschool programs for all children on a representative sample of 106 Slovenian preschool principals by means of quantitative pedagogical research. The results show a high percentage of disadvantaged children in the preschool areas and in the preschools themselves; on the other hand, only a low percentage (only one-third of preschools collect data about disadvantaged children and implement preschool programs for them; only one-fifth of preschools implement preschool programs for disadvantaged children. In order to act responsibly and enable all children the right to education, we must start devoting greater attention to identifying and including disadvantaged children in preschool programs.

    Shelley Stagg Peterson

    2012-12-01

    Full Text Available This paper reports on research examining how library staff in 10 Ontario libraries’ preschool literacy programs support three- and four-year-old children’s early literacy and school readiness as well as their parents’ and caregivers’ literacy interactions with their children. Multiple data sources included surveys of 82 parents/caregivers, observations of a sample of 65 of the 198 children at the sessions we visited, and interviews with10 library staff. Observations were analyzed for evidence of children’s development of print motivation, phonological awareness, vocabulary, narrative skills, and print awareness: early literacy skills and knowledge that have been shown to be reliably and significantly correlated with future reading success. Analysis of the observational and interview data showed that the programs have been very successful in fostering children’s readiness to participate in school activities and their motivation to read. Participating children learned new vocabulary, demonstrated an awareness of rhymes and sounds of language, and showed an understanding of books that were read by library staff: all early literacy behaviours that are foundational to later literacy development. The programs have also provided parents/caregivers with new ways to interact with children to engage them with books and with print at home. The development of children’s school readiness skills and parents’ awareness of how to support their children’s literacy are outcomes extending beyond library staff goals for their library programs and should be included in literature advertising the programs. Print awareness is an area of literacy development that library staff could encourage to a greater extent, however. Very few instances of such behaviour were observed, with most of the observations taking place in two of the preschool early literacy programs. Concomitantly, developing children’s print awareness is a recommended topic for

    Full Text Available Despite advances in behavioral and pharmacological treatment for tobacco use and dependence, quit rates remain suboptimal. Increasing physical activity has shown some promise as a strategy for improving cessation outcomes. However, initial efficacy studies focused on intensive, highly structured exercise programs that may not be applicable to the general population of smokers. We describe the rationale and study design and report baseline participant characteristics from the Lifestyle Enhancement Program (LEAP, a two-group, randomized controlled trial. Adult smokers who engaged in low levels of leisure time physical activity were randomly assigned to treatment conditions consisting of an individualized physical activity intervention delivered by health fitness instructors in community-based exercise facilities or an equal contact wellness control. All participants received standard cognitive behavioral smoking cessation counseling combined with nicotine replacement therapy. The primary outcomes are seven-day point prevalence abstinence at seven weeks, six- and 12 months. Secondary outcomes include self-reported physical activity, dietary intake, body mass index, waist circumference, percent body fat, and nicotine withdrawal symptoms. Participants consist of 392 sedentary smokers (mean [standard deviation] age = 44.6 [10.2] = years; 62% female; 31% African American.

    2018-01-01

    Executive functions (EFs) play a critical role in cognitive and social development. During preschool years, children show not only rapid improvement in their EFs, but also appear sensitive to developmentally appropriate interventions. EMIL is a training program for German preschool teachers that was developed and implemented to improve the EFs of preschoolers. The aim of the present study was to evaluate its effects on the EFs of children between three and six years old. The teacher training (eight sessions, 28.5 hours) was implemented in four preschools. The EFs of children of the intervention group (n = 72, 32 girls, Mage = 48 months) and the control group of four other matched preschools (n = 61, 27 girls, Mage = 48 months) were tested before, during, and after the intervention using different measures assessing working memory, inhibitory control, and cognitive flexibility. The intervention group showed significant gains on three out of seven EF tests (behavioral inhibition, visual-spatial working memory, and combined EFs) compared to the control group. Post hoc analyses for children with low initial EFs scores revealed that participation in the intervention led to significant gains in inhibitory control, visual-spatial working memory, and phonological working memory as well as a marginally significant difference for combined EFs. However, effect sizes were rather small. The results suggest that teacher training can lead to significant improvements in preschooler's EFs. Although preliminary, the results could contribute to the discussion on how teacher training can facilitate the improvement of EFs in preschool children.

    2010-02-01

    This paper estimates the rate of return to the High/Scope Perry Preschool Program, an early intervention program targeted toward disadvantaged African-American youth. Estimates of the rate of return to the Perry program are widely cited to support the claim of substantial economic benefits from preschool education programs. Previous studies of the rate of return to this program ignore the compromises that occurred in the randomization protocol. They do not report standard errors. The rates of return estimated in this paper account for these factors. We conduct an extensive analysis of sensitivity to alternative plausible assumptions. Estimated annual social rates of return generally fall between 7-10 percent, with most estimates substantially lower than those previously reported in the literature. However, returns are generally statistically significantly different from zero for both males and females and are above the historical return on equity. Estimated benefit-to-cost ratios support this conclusion.

    Full Text Available Introduction: Family centres in Sweden are integrated services that reach all prospective parents and parents with children up to their sixth year, because of the co-location of the health service with the social service and the open pre-school. The personnel on the multi-professional site work together to meet the needs of the target group. The article explores a program theory focused on the open pre-schools at family centres.Method: A multi-case design is used and the sample consists of open pre-schools at six family centres. The hypothesis is based on previous research and evaluation data. It guides the data collection which is collected and analysed stepwise. Both parents and personnel are interviewed individually and in groups at each centre.Findings: The hypothesis was expanded to a program theory. The compliance of the professionals was the most significant element that explained why the open access service facilitated positive parenting. The professionals act in a compliant manner to meet the needs of the children and parents as well as in creating good conditions for social networking and learning amongst the parents. Conclusion: The compliance of the professionals in this program theory of open pre-schools at family centres can be a standard in integrated and open access services, whereas the organisation form can vary. The best way of increasing the number of integrative services is to support and encourage professionals that prefer to work in a compliant manner.

    Full Text Available Abstract Background Early childhood services have been identified as a key setting for promoting healthy eating and physical activity as a means of preventing overweight and obesity. However, there is limited evidence on effective nutrition and physical activity programs in this setting. The purpose of this study was to evaluate Munch and Move, a low-intensity, state-wide, professional development program designed to support early childhood professionals to promote healthy eating and physical activity among children in their care. Methods The evaluation involved 15 intervention and 14 control preschools (n = 430; mean age 4.4 years in Sydney, New South Wales, Australia and was based on a randomised-control design with pre and post evaluation of children's lunchbox contents, fundamental movement skills (FMS, preschool policies and practices and staff attitudes, knowledge and confidence related to physical activity, healthy eating and recreational screen time. Results At follow up, FMS scores for locomotor, object control and total FMS score significantly improved by 3.4, 2.1 and 5.5 points more (respectively in the intervention group compared with the control group (P Conclusion The findings suggest that a low intensity preschool healthy weight intervention program can improve certain weight related behaviours. The findings also suggest that change to food policies are difficult to initiate mid-year and potentially a longer implementation period may be required to determine the efficacy of food policies to influence the contents of preschoolers lunchboxes.

    Full Text Available This study aims to evaluate the effect of phonological awareness training program in preschool performance of 256 children in Funchal, Portugal. This is a longitudinal study from preschool (2005 to 4th grade (2011. It has an experimental design. The sample includes an Experimental Group (132 children and a Control group (124 children. We pretend to answer the following research question: To what degree does training children in phonological awareness as early as preschool have short-term and long-term effects on the evolution of students' competencies and disciplinary knowledge? A first evaluation done in 2006 on the effects of this program at the end of preschool education revealed that the Experimental Group presented significant improvements when compared to the Control Group on the considered dimensions. In 2011, the Experimental Group presented Math National Test higher significant results when compared to the Control Group. The Experimental Group's Portuguese National Test presented better results than the Control Group one, but not significantly. This seems to indicate that Phonological Awareness Program can bring benefits and prevent long-term math school failure.

    Recently, nonmaternal center-based child care has been linked to problem behavior in young children (National Institute of Child Health and Human Development, 2003). In response, a comprehensive program to promote prosocial skills was evaluated in a classroom of 16 children between the ages of 3 and 5 years. Classroom observations were conducted during evocative situations to determine the likelihood of problem behavior (noncompliance, vocal or motor disruptions, aggression) and preschool life skills. A classwide teaching program was then implemented in a staggered manner across instruction following, functional communication, delay tolerance, and friendship skills. These four categories of preschool life skills, which included two to four related skills, were selected for classwide teaching because they were either identified by educators as important for early school success, have often been taught following functional assessments of more severe problem behavior, or both. Skills were taught on a classwide basis during typically scheduled activities (circle, free play, transitions, meals) via instructions, modeling, role play, and feedback. A multiple probe design showed that the program resulted in an 74% reduction in problem behavior and a more than four-fold increase in preschool life skills. Similar beneficial effects of the program were evident in questionnaire data gathered prior to and at the close of the evaluation. Finally, the teachers who implemented the program reported overall high levels of satisfaction with the classwide teaching program, the target skills, and the results. Implications for the design of early childhood experiences for preempting the development of serious problem behavior are discussed.

    Full Text Available Objective: To establish preferences of parents and guardians of preschool children for the organization of preschool vaccination services, including financial incentives. Design: An online discrete choice experiment. Participants: Parents and guardians of preschool children (up to age 5 years who were (n = 259 and were not (n = 262 classified as at high risk of incompletely vaccinating their children. High risk of incomplete vaccination was defined as any of the following: aged less than 20 years, single parents, living in one of the 20% most deprived areas in England, had a preschool child with a disability, or had more than three children. Main Outcome Measures: Participant preferences expressed as positive (utility or negative (disutility on eight attributes and levels describing the organization of preschool vaccination programs. Results: There was no difference in preference for parental financial incentives compared to no incentive in parents “not at high risk” of incomplete vaccination. Parents who were “at high risk” expressed utility for cash incentives. Parents “at high risk” of incomplete vaccination expressed utility for information on the risks and benefits of vaccinations to be provided as numbers rather than charts or pictures. Both groups preferred universally available, rather than targeted, incentives. Utility was identified for shorter waiting times, and there were variable preferences for who delivered vaccinations. Conclusions: Cash incentives for preschool vaccinations in England would be welcomed by parents who are “at high risk” of incompletely vaccinating their children. Further work is required on the optimal mode and form of presenting probabilistic information on vaccination to parents/guardians, including preferences on mandatory vaccination schemes.

    oscillating light `waves' had to be quantized as well. Several articles in this issue of Physics Education celebrate the first year of the quantum, 1900. I am grateful and beholden to Board Member and co-editor Gren Ireson for his contacts and nomination of the various contributors. It does seem strange, however, a full century after its discovery full of its amazing success that the essential quantum nature of practically everything is still kept hidden from school students, in the UK at least. Let's see what happens in the coming century. Now for another quantum leap. This is the last issue of Physics Education that I shall have the honour of editing. In fact, I shall leap into historical obscurity as the very last honorary editor. Great efforts by your Editorial Board - over a fair number of years! - have resulted in a radical reorganizing of both the journal and the way it is produced. It's been an interesting five years, a time of falling numbers but quite radical innovations in post-16 physics education. IoPP and the IoP are working together to revitalize what may have been seen by many as a staid if respectable and authoritative publication. We shall keep the authority and even respectability but hope to liven things up a bit. The new editor is Kerry Parker of Sheffield College. She will take on a stronger role than I and my predecessors have had, and will be working at IoPP in Bristol two days a week. There are many obvious advantages in this, and I look forward to seeing the new design and approach that will start with the January 2000 issue. So, it's goodbye from me - and also from the unsung heroine of Physics Education for even longer. Managing Editor Dr Jill Membrey has been doing the really hard work at Bristol for many years, but is now moving on to other things at IoPP. I am extremely grateful for the highly professional care and support she has provided for myself and the Editorial Board over the years. The new Managing Editor is Andrea Pomroy, who arrives at

    Childhood obesity is among the leading health concerns in the United States. The relationship between unmet physical activity needs in young children is of particular interest as the trend in childhood obesity continues to rise and unmet physical activity needs are identified. The preschool years are an influential time in promoting healthful lifestyle habits and early childhood interventions may help establish lifelong healthful behaviors which could help prevent obesity later in life. The Food Friends®: Get Movin' with Mighty Moves® is a preschool physical activity program which aims to improve children's gross motor skills and physical activity levels. The home environment and parental modeling are critical factors related to child physical activity in this population. The parent component, Mighty Moves®: Fun Ways to Keep Families Active and Healthy, was designed to address barriers in the home environment that lead to unmet physical activity needs in preschoolers and their families. The program and materials were designed based on Social Marketing tenets and Social Learning Theory principles. Four Colorado Head Start centers were assigned to an experimental group as part of the Mighty Moves® group randomized trial. Quantitative and qualitative evaluation methods were used to determine what messages and materials reached and motivated the target audience to increase physical activity levels. Results of the study indicated the program's materials helped families and children to be more physically active. Additionally, materials and material dissemination were revised to enhance program goals.

    Keeping older adults healthy and active is an emerging challenge of an aging society. Despite the importance of personal relationships to their health and well-being, changes in family structure have resulted in a lower frequency of intergenerational interactions. Limited studies have been conducted to compare different interaction style of intergenerational interaction. The present study aimed to compare the changes in visual attention, facial expression, engagement/behaviour, and intergenerational conversation in older adults brought about by a performance-based intergenerational (IG) program and a social-oriented IG program to determine a desirable interaction style for older adults. The subjects of this study were 25 older adults who participated in intergenerational programs with preschool children aged 5 to 6 years at an adult day care centre in Tokyo. We used time sampling to perform a structured observation study. The 25 older participants of intergenerational programs were divided into two groups based on their interaction style: performance-based IG program (children sing songs and dance) and social-oriented IG program (older adults and children play games together). Based on the 5-minute video observation, we compared changes in visual attention, facial expression, engagement/behaviour, and intergenerational conversation between the performance-based and social-oriented IG programs. Constructive behaviour and intergenerational conversation were significantly higher in the social-oriented IG programming group than the performance-based IG programming group (pprogramming group than the performance-based IG programming (pprogramming group than the social-oriented IG programming group (pprograms with preschool children brought smiles and conversation to older adults. The social-oriented IG program allowed older adults to play more roles than the performance-based IG program. The intergenerational programs provide opportunities to fulfil basic human needs and

    The change in people's dietary life has led to an increase in an intake of processed foods and food chemicals, raising awareness about taste education for preschoolers whose dietary habits start to grow. This study aims to evaluate the effectiveness and satisfaction of parents and childcare personnel after developing a taste education program and demonstrating it in class. A part of the curriculum developed by Piusais and Pierre was referred for the program. After educating 524 preschoolers in child care facilities in Seoul, a satisfaction survey was conducted on the program. The data in this study were analyzed using SPSS 14.0. Statistical analysis was conducted based on the frequency after collecting the data. Mean ± SD used to determine satisfaction with taste education, with preferences marked on a five-point scale and the alpha was set at 0.05. The program includes five teachers' guides with subjects of sweetness, saltiness, sourness, bitterness and harmony of flavor, and ten kinds of teaching tools. For the change in parents' recognition of the need for taste education based on five-point scale, the average of 4.06 ± 0.62 before the program has significantly increased to 4.32 ± 0.52 (P facilities, the average scores for education method, education effect, education contents and nutritionists, and teaching tools were at 4.15 ± 0.63, 3.91 ± 0.50, 4.18 ± 0.50, and 3.80 ± 0.56 respectively. In addition, the need for a continuous taste education scored 4.42 ± 0.67. This program has created a positive change in preschoolers' dietary life, therefore the continuation and propagation of the taste education program should be considered.

    Previous studies have demonstrated the efficacy of early intervention for anxiety in preschoolers through parent-education. The current study evaluated a six-session early intervention program for preschoolers at high risk of anxiety disorders in which a standard educational program for parents was supplemented by direct training of social skills to the children. Seventy-two children aged 3-5 years were selected based on high behavioural inhibition levels and concurrently having a parent with high emotional distress. Families were randomly assigned to either the intervention group, which consisted of six parent-education group sessions and six child social skills training sessions, or waitlist. After six months, families on waitlist were offered treatment consisting of parent-education only. Relative to waitlist, children in the combined condition showed significantly fewer clinician-rated anxiety disorders and diagnostic severity and maternal (but not paternal) reported anxiety symptoms and life interference at six months. Mothers also reported less overprotection. These gains were maintained at 12-month follow-up. Parent only education following waitlist produced similar improvements among children. Quasi-experimental comparison between combined and parent-only interventions indicated greater reductions from combined intervention according to clinician reports, but no significant differences on maternal reports. Results suggest that this brief early intervention program for preschoolers with both parent and child components significantly reduces risk and disorder in vulnerable children. The inclusion of a child component might have the potential to increase effects over parent-only intervention. However, future support for this conclusion through long-term, randomised controlled trials is needed. Copyright © 2017 Elsevier Ltd. All rights reserved.

  20. Hybrid chernoff tau-leap

    KAUST Repository

    Moraes, Alvaro

    2014-01-01

    Markovian pure jump processes model a wide range of phenomena, including chemical reactions at the molecular level, dynamics of wireless communication networks, and the spread of epidemic diseases in small populations. There exist algorithms such as Gillespie\\'s stochastic simulation algorithm (SSA) and Anderson\\'s modified next reaction method (MNRM) that simulate a single path with the exact distribution of the process, but this can be time consuming when many reactions take place during a short time interval. Gillespie\\'s approximated tau-leap method, on the other hand, can be used to reduce computational time, but it may lead to nonphysical values due to a positive one-step exit probability, and it also introduces a time discretization error. Here, we present a novel hybrid algorithm for simulating individual paths which adaptively switches between the SSA and the tau-leap method. The switching strategy is based on a comparison of the expected interarrival time of the SSA and an adaptive time step derived from a Chernoff-type bound for the one-step exit probability. Because this bound is nonasymptotic, we do not need to make any distributional approximation for the tau-leap increments. This hybrid method allows us (i) to control the global exit probability of any simulated path and (ii) to obtain accurate and computable estimates of the expected value of any smooth observable of the process with minimal computational work. We present numerical examples that illustrate the performance of the proposed method. © 2014 Society for Industrial and Applied Mathematics.

    Full Text Available It has been aimed to examine the acquisition and indicators in the Pre-school Education Program 2013, updated and implemented in 2013, according to the development areas in terms of values education in the study. For this purpose, content analysis method from qualitative research methods was used. The values addressed with in the direction of the theory of values have been divided into categories and subcategories. The final form of the category of values was given in line with the opinion of experts. The specified values have been analyzed according to their status of acquisition and indicators for children. As a result of the study, it has been found that the value of responsibility was given a great place in the pre-school education program and it is followed by the values of respect, solidarity, trust, love, tolerance, freedom, equality, friendship and justice respectively.  Depending on the results obtained, it may be recommended that more attention is paid to the individual interests and needs of children, all values are equally integrated into the program and school-family cooperation is ensured about the values.

    The effects of multidisciplinary treatment programs on eating behavior in overweight preschool-aged children are largely unknown. We evaluated a multidisciplinary intervention program on eating behavior in 3- to 5-year-old overweight children, comparing them with children given standard treatment. We also assessed the parental eating behavior changes and investigated associations between parents and children. We randomized 75 children to a multidisciplinary intervention or to a standard care program. During a 16-week period, children and parents in the multidisciplinary group were given dietary advice, physical activity sessions and, for parents only, psychological counseling. Children and parents in the standard group visited a pediatrician 3 times and were given information on a healthy lifestyle. At baseline, after 16 weeks, and after 12 months, children were measured and parents completed the Dutch Child Eating Behavior Questionnaire (DEBQ-C) for their children and the DEBQ for themselves. At the three time points, 70 (93.3%), 57 (91.9%), and 42 (73.7%) DEBQ-Cs were analyzed. We found no differences in the changes in eating behavior between the two groups over time. In both groups, there was a significant increase in restrained eating behavior present at 16 weeks, however, this was no longer present at 12 months. We found no associations between changes in eating behavior between the children and their parents. A multidisciplinary obesity intervention program in preschool-aged children induced more restrained eating behavior between baseline and 16 weeks. However, there was no difference with the children in the standard care group.

    Within an at-risk sample of preschoolers with externalizing behavior problems (EBP), the current study examined the initial promise of a multimodal intervention, the Summer Treatment Program for Pre-Kindergarteners (STP-PreK), in improving parenting outcomes. Using an open trial design, 154 parents and their preschool children (73% male; M age  = 5.06 years; 82% Hispanic/Latino background) with at-risk or clinically elevated levels of EBP (57% of which were referred by schools or mental health/medical professionals) completed a baseline and post-treatment assessment. A subsample of 90 families completed a follow-up assessment approximately 6 to 9 months after treatment completion. Parental measures of parenting stress and discipline strategies were collected across all three assessments. Observational data were also collected across all assessments during a 5-min standardized child-led play situation and a 5-min parent-led clean up task. The parenting component of the STP-PreK included a School Readiness Parenting Program (SRPP) of which the behavioral management component was implemented via a Parent-Child Interaction Therapy (PCIT) adaptation (8 weekly group sessions with 15-20 parents in each group, lack of requirement of "mastery" criteria). All parenting outcomes (both ratings and observed) significantly improved after the intervention (Cohen's d mean effect size across measures 0.89) with all effects being maintained at the 6-9 month follow-up. These findings highlight the initial promise of our SRPP's PCIT adaptation in targeting multiple aspects of parenting while yielding comparable parenting skills acquisition compared to traditional individual PCIT.

  13. Using social impact borrowing to expand preschool through third grade programs in urban public schools.

    Science.gov (United States)

    Temple, Judy A; Reynolds, Arthur J

    Budget constraints and difficulty raising taxes limit school districts from expanding education programming even when research shows that additional expenditures would generate economic benefits that are greater than costs. Recently, coalitions of private investors, philanthropists, education practitioners, and government finance analysts have emerged to create opportunities to expand education services that promise high rates of social net benefits without raising taxes or reducing other expenditures. These collaborators have a strong interest in obtaining careful estimates of educational program effectiveness. We describe the use of social-impact borrowing to increase access to the Child-Parent Center preschool-through-third-grade intervention for at-risk students in the Chicago Public School District. The partners include the city, school district, investors, nonprofit organizations, and a university. The key to the feasibility of social-impact borrowing is the ability to document that early intervention can reduce the need for later special-education services. With the help of private investors and nonprofit organizations, it is possible for public school districts to finance services with funds from private sources and use future cost savings to repay this debt. We discuss how social-impact borrowing is being used in Chicago and in Salt Lake County as the nation's first two instances of using pay-for-performance social-impact borrowing to support early education.

    The development of preschool children of Aboriginal heritage is jeopardized by the inter-generational transmission of risk that has created, and continues to create, social disadvantage. Early intervention programs are intended to mitigate the impact of social disadvantage. Yet, evidence of the effectiveness of these programs for children of Aboriginal heritage is limited. The purpose of this study was to examine the effects of a two-generation, multi-cultural preschool program on 45 children of Aboriginal heritage and their caregivers. We used a single-group, pretest (program intake)/posttest (program exit) design with follow-up when the children were 7 years old. We used an observational measure of child receptive language (Peabody Picture Vocabulary Test-III) and caregiver-reported measures of child development (Nipissing District Developmental Screen), risk for child maltreatment (Adult-Adolescent Parenting Inventory; AAPI), parenting stress (Parenting Stress Index; PSI), self-esteem (Rosenberg Self-Esteem scale; RSE), and life skills (Community Life Skills scale; CLS). Using paired t-tests we found statistically significant increases in child receptive language scores between intake and exit, and repeated-measures ANOVA showed that these improvements were maintained up to age 7 years. For caregivers, Pearson's correlations demonstrated that risk for child maltreatment, parenting stress, self-esteem, and life skills were stable over time. Results of this study suggest that children of Aboriginal heritage can benefit from participation in a two-generation, multi-cultural preschool program. Their caregivers may have received greater benefit if issues of intergenerational transmission of the negative influences of residential schools were addressed as part of programming.

    The aim was to calculate the total and the net costs per child included in a 3-year caries preventive program for preschool children and to make estimates of expected lowest and highest costs in a sensitivity analysis. The direct costs for prevention and dental care were applied retrospectively to a comprehensive oral health outreach project for preschool children conducted in a low-socioeconomic multi-cultural urban area. The outcome was compared with historical controls from the same area with conventional dental care. The cost per minute for the various dental professions was added to the cost of materials, rental facilities and equipment based on accounting data. The cost for fillings was extracted from a specified per diem list. Overhead costs were assumed to correspond to 50% of salaries and all costs were calculated as net present value per participating child in the program and expressed in Euro. The results revealed an estimated total cost of 310 Euro per included child (net present value) in the 3-year program. Half of the costs were attributed to the first year of the program and the costs of manpower constituted 45% of the total costs. When the total cost was reduced with the cost of conventional care and the revenue of avoided fillings, the net cost was estimated to 30 Euro. A sensitivity analysis displayed that a net gain could be possible with a maximal outcome of the program. In conclusion, the estimated net costs were displayed and available to those considering implementation of a similar population-based preventive program in areas where preschool children are at high caries risk.

    Comparative analysis of the efficacy of a playful-narrative program to teach mathematics at pre-school level. In this paper, the effectiveness of a programme comprising several components that are meant to consolidate mathematical concepts and abilities at the pre-school level is analyzed. The instructional methodology of this programme is compared to other methodologies. One-hundred 5-6 year-old children made up the sample that was distributed in the following conditions: (1) traditional methodology; (2) methodology with perceptual and manipulative components, and (3) methodology with language and playful components. Mathematical competence was assessed with the Mathematical Criterial Pre-school Test and the subtest of quantitative-numeric concepts of BADyG. Participants were evaluated before and after the academic course during which they followed one of these methodologies. The results show that the programme with language and playful components is more effective than the traditional methodology (p<.000) and also more effective than the perceptual and manipulative methodology (p<.000). Implications of the results for instructional practices are analyzed.

    2018-05-01

    In this paper, I describe the development of the Irie Classroom Toolbox, a school-based violence prevention, teacher training program for use with children aged 3-6 years. In-depth interviews were conducted with Jamaican preschool teachers, who had participated in a trial of a classroom behavior management program, at posttest (n = 35) and 5 years later (n = 20). An on-going process evaluation was also conducted. Teachers' preferred behavior management strategies and training methods were documented, and enablers and barriers to implementation were identified. Teachers were most likely to adopt strategies that they liked, found easy to use, and were effective. These included paying attention to positive behavior and explicitly teaching children the expected behavior. Teachers preferred active, hands-on training strategies based on social-cognitive theories. Enablers to intervention implementation included positive teacher-facilitator relationships, choice, collaborative problem solving, teachers recognizing benefits of the intervention, group support, and provision of materials. Barriers to intervention implementation were also identified. These data were integrated with behavior change theory (i.e., the behavior change wheel and theoretical domains framework) to develop an intervention grounded in common core elements of evidence-based programs while also utilizing teachers' perspectives. The resulting program is a low cost, adaptable intervention that should be suitable for training preschool teachers in other low-resource settings. © 2018 The Authors.

    2018-04-01

    This paper proposed a novel puppet play method utilizing recent technology. An interactive puppet game has been developed based on the theme of a famous Chinese classical novel. This project was implemented using Unreal Engine, which is a leading software of integrated tools for developers to design and build games. On the other hand, Leap Motion Controller is a sensor device for recognizing hand movements and gestures. It is commonly used in systems which require close-range finger-based user interaction. In order to manipulate puppets’ movements, the developed program employs the Leap Motion SDK, which provides a friendly way to add motion-controlled 3D hands to an Unreal game. The novelty of our project is to replace 3D model of rigged hands by two 3D humanoid rigged characters. The challenges of this task are two folds. First, the skeleton structure of a human hand and a humanoid character (i.e., puppets) are totally different. Making the puppets to follow the hand poses of the user and yet ensuring reasonable puppets’ movements has not been discussed in the literatures nor in the developer forums. Second, there are only a limited number of built-in recognizable hand gestures. More recognizable hand gestures need to be created for the interactive game. This paper reports the proposed solutions to these challenges.

  6. Multilevel hybrid Chernoff tau-leap

    KAUST Repository

    Moraes, Alvaro

    2015-04-08

    In this work, we extend the hybrid Chernoff tau-leap method to the multilevel Monte Carlo (MLMC) setting. Inspired by the work of Anderson and Higham on the tau-leap MLMC method with uniform time steps, we develop a novel algorithm that is able to couple two hybrid Chernoff tau-leap paths at different levels. Using dual-weighted residual expansion techniques, we also develop a new way to estimate the variance of the difference of two consecutive levels and the bias. This is crucial because the computational work required to stabilize the coefficient of variation of the sample estimators of both quantities is often unaffordable for the deepest levels of the MLMC hierarchy. Our method bounds the global computational error to be below a prescribed tolerance, TOL, within a given confidence level. This is achieved with nearly optimal computational work. Indeed, the computational complexity of our method is of order O(TOL−2), the same as with an exact method, but with a smaller constant. Our numerical examples show substantial gains with respect to the previous single-level approach and the Stochastic Simulation Algorithm.

Using dual-weighted residual expansion techniques, we also develop a new way to estimate the variance of the difference of two consecutive levels and the bias. This is crucial because the computational work required to stabilize the coefficient of variation of the sample estimators of both quantities is often unaffordable for the deepest levels of the MLMC hierarchy. Our method bounds the global computational error to be below a prescribed tolerance, TOL, within a given confidence level. This is achieved with nearly optimal computational work. Indeed, the computational complexity of our method is of order O(TOL−2), the same as with an exact method, but with a smaller constant. Our numerical examples show substantial gains with respect to the previous single-level approach and the Stochastic Simulation Algorithm.

    With the development of computer vision, virtual reality has been applied in astronaut virtual training. As an advanced optic equipment to track hand, Leap Motion can provide precise and fluid tracking of hands. Leap Motion is suitable to be used as gesture input device in astronaut virtual training. This paper built an astronaut virtual training based Leap Motion, and established the mathematics model of hands occlusion. At last the ability of Leap Motion to handle occlusion was analysed. A virtual assembly simulation platform was developed for astronaut training, and occlusion gesture would influence the recognition process. The experimental result can guide astronaut virtual training.

  11. Interim report on nodel evaluation methodology and the evaluation of LEAP

    Energy Technology Data Exchange (ETDEWEB)

    1980-04-01

    This report describes progress made at ORNL toward development and demonstration of a methodology for evaluating energy-economic modeling codes and important results derived from these codes. To bolster traditional evaluation methods with more-quantitative procedures of interest to the Energy Information Administration, ORNL is applying sensitivity theory as part of a comprehensive effort to quantify the importance of various data and model parameters to the key results that are of interest. The Long-Term Energy Analysis Program (LEAP) was chosen as the initial focus for the research. LEAP is an energy-economy model which resides in the Long-Term Energy Analysis Division (LTEAD) of the Integrative Analysis Group in the Office of Applied Analysis, EIA. LTEAD developed Model 22C of LEAP for two reasons: (1) to prepare projections through the year 2020, which were needed for the 1978 EIA Annual Report to Congress and (2) to develop a base for analyses of specific options for Federal action. LEAP Model 22C and its uses are described to provide the background for this interim description of the model evaluation effort at ORNL. 19 figures, 10 tables.

    2012-01-01

    The authors compared the involvement in children's development and education of 38 fathers of preschoolers with hearing loss to the involvement of a matched group of 36 fathers of preschoolers with normal hearing, examining correlations between child, father, and family characteristics. Fathers completed self-reports regarding their parental involvement and parenting self-efficacy and reported on their family cohesion and adaptability. Mothers also reported on their husbands' involvement. Similarly high levels of involvement on the part of both groups of fathers were found. Involvement correlated positively with fathers' self-reported parenting self-efficacy, family cohesion, and adaptability, and mother-reported paternal involvement. Implications for professionals and mothers are discussed, including the need to encourage mothers' support for their husbands' involvement and to empower fathers' sense of competency in order to increase their involvement.

    This study examined the extent to which an evidence-based preschool curriculum (Head Start REDI) was sustained by 20 teachers during the year following a randomized controlled efficacy trial, when teachers were no longer required by the research project to implement the curriculum. Two quantitative measures of sustainability (teacher ratings, REDI coach ratings) and a qualitative measure (teacher interview) were collected and compared. Sustainability varied by the specific curriculum component, with higher rates of sustainability for the social-emotional component (Preschool PATHS) than for the language and literacy components. Estimates of sustainability were affected by the method of measurement, with REDI coach ratings and qualitative teacher interviews more closely aligned than teacher ratings. Responses from qualitative interviews identified the main factors that teachers thought affected sustainability. Teacher responses suggest that efforts to promote sustainability are best targeted at reducing barriers, such as competing demands, rather than simply highlighting the benefits of the new curriculum.

    2017-03-01

    Full Text Available Being aware of the changes which occur under the influence of environmental conditions, education, culture and social roles upon the child is indispensable with a view to build up a conduct adapted to the social environment. For any preschooler child, entering kindergarten is an important social event and getting adapted to the new situation is not easy. Broadening the relational framework with objects, other individuals, with one’s own self, results in disciplining preschooler conducts and increasing the number of socially desirable conducts. Relying upon the above statements, this study is aimed at working out a social learning programme made up of motion games involving socialization/cooperation elements intended for inducing amelioration in terms of the child’s conduct during the process of adaptation to the kindergarten environment. The experiment was conducted using a sample of “little group” preschoolers (children 3-4 years of age. As research methods, the following have been used: studying the reference literature, the method of pedagogical observation, the method of experiment and the method of playing. Further to the practical application of the programme worked out with a view to enhance the adaptation conduct in the said subjects, the experimental group proved to have undergone a significant positive evolution and each subject showed improvements considering the conduct of adaptation to kindergarten conditions, as highlighted by the change i.e. higher values in terms of the individual scores achieved at the final test. Preschool education is meant to provide all possible ways and means to enable any child’s integration into groups of children of a peer age, to develop sociability in children and to create favorable conditions for building out inter-children networks.

    2016-01-01

    Full Text Available Raising a child with a developmental disability can be a serious challenge for parents, which leads to increased parenting stress and has multiple impacts on family well-being. Even though there is a well recognized need for support for parents of children with disabilities, our country lacks the systematized support programs and their evaluations. Program 'Our Story' aims to educate parents about the key processes that lead to accepting the child's condition and recognizing an appropriate care model for a child with disabilities. The program is based on attachment theory and the importance of resolution to diagnosis- emotional and cognitive acceptance of the child's health condition and its implications. It is a structured program, consisting of six thematic meetings with a group of parents. The group counseling is led by two professionals who have previously undergone a 32-hour program for the implementation of training. This paper presents the experiences from two preschool institutions, in which the program was implemented and evaluated. Also it discusses the importance and possibilities of implementing a support program for parents of children with disability in the context of early education system.

    2011-01-01

    The impact of a newly designed computer-assisted treatment (C-AT) program, My Sentence Builder, for the remediation of expressive-grammar deficits in children with specific language impairment (SLI) was explored. This program was specifically designed with features to directly address expressive-grammar difficulties, thought to be associated with hypothesized deficits in verbal working memory (VWM). Thirty-four preschoolers with deficits in expressive-grammar morphology participated. Using the randomization procedure of consecutive sampling, participants were recruited. Twenty-two participants were consecutively assigned to one of two treatment groups, C-AT or non C-AT (nC-AT). The nC-AT utilized conventional language stimulation procedures containing features which have been traditionally used to address expressive-grammar deficits. A group of equivalent children awaiting treatment and chosen from the same sample of children as the treatment participants served as a control group. Blind assessments of outcomes were completed pre-, post-, and 3-months post-treatment in a formal and informal context. C-AT and nC-AT participants significantly outperformed controls pre-to-post to 3-months post-treatment in both assessment contexts. No significant differences in treatment gains were found between C-AT and nC-AT. Results suggested that treatments designed to directly address expressive-grammar deficits were better than no treatment for preschool SLI. Further, use of a C-AT program may be another feasible treatment method for this disorder population. As a result of this activity, the reader will recognize that: (1) expressive-grammar treatment is better than no treatment for immediate and continued language growth, (2) use of a C-AT program containing specific features designed to directly address expressive-grammar deficits is another viable, but not necessarily a better treatment option for the remediation of expressive-grammar deficits in preschool children with SLI

    Available evidence indicates that early intervention programs, such as the Early Start Denver Model (ESDM), can positively affect key outcomes for children with Autism Spectrum Disorder (ASD). However, programs involving resource intensive one-to-one clinical intervention are not readily available or deliverable in the community, resulting in many children with ASD missing out on evidence-based intervention during their early and most critical preschool years. This study evaluated the effectiveness of the ESDM for preschool-aged children with ASD using a predominantly group-based intervention in a community child care setting. Participants were 26 children (21 male) with ASD with a mean age of 49.6 months. The ESDM, a comprehensive early intervention program that integrates applied behaviour analysis with developmental and relationship-based approaches, was delivered by trained therapists during the child's attendance at a child care centre for preschool-aged children with ASD. Children received 15-20 hours of group-based, and one hour of one-to-one, ESDM intervention per week. The average intervention period was ten months. Outcome measures were administered pre- and post-intervention, and comprised a developmental assessment - the Mullen Scales of Early Learning (MSEL); and two parent-report questionnaires - the Social Communication Questionnaire (SCQ) and Vineland Adaptive Behaviours Scales-Second Edition (VABS-II). Statistically significant post-intervention improvements were found in children's performance on the visual reception, receptive language and expressive language domains of the MSEL in addition to their overall intellectual functioning, as assessed by standardised developmental quotients. Parents reported significant increases in their child's receptive communication and motor skills on the VABS-II, and a significant decrease in autism-specific features on the SCQ. These effects were of around medium size, and appeared to be in excess of what may

    Full Text Available Research exists on using instructional gardening programs with school age children as a means of improving dietary quality and for obesity prevention. This article examines the potential use of instructional gardens in childcare settings to improving fruit and vegetable intake in young children. A qualitative study was conducted with childcare providers. Participants (n=20 were recruited via e-mails, letters, and follow-up phone calls. Interviews were recorded, transcribed, and coded to identify themes within two areas (1 childcare providers perceptions of children’s fruit and vegetable consumption and (2 components necessary to initiate or improve instructional gardening programs. Themes associated with provider’s perceptions of child fruit and vegetable consumption included benefits of consumption, willingness to try fruits and vegetables, meeting recommendations, and influence of the home and childcare environments on child eating. Benefits, barriers, and resources needed were identified as themes related to starting or improving instructional gardening programs. Benefits to gardening with preschoolers are consistent with those found in school-age populations. While several barriers exist, resources are available to childcare providers to address these barriers. Increased knowledge and awareness of resources are necessary to improve the success of gardening programs in the childcare setting with the goal of improving child diet quality.

    The dynamics of biochemical reactive systems with small copy numbers of one or more reactant molecules is dominated by stochastic effects. For those systems, discrete state-space and stochastic simulation approaches were proved to be more relevant than continuous state-space and deterministic ones. In systems characterized by having simultaneously fast and slowtimescales, the existing discrete space-state stochastic path simulation methods such as the stochastic simulation algorithm (SSA) and the explicit tauleap method can be very slow. Implicit approximations were developed in the literature to improve numerical stability and provide efficient simulation algorithms for those systems. In this work, we propose an efficient Multilevel Monte Carlo method in the spirit of the work by Anderson and Higham (2012) that uses drift-implicit tau-leap approximations at levels where the explicit tauleap method is not applicable due to numerical stability issues. We present numerical examples that illustrate the performance of the proposed method.

    The purpose of this study was to provide new insight into common barriers to the availability and use of nutrition education (NE) resources in Head Start preschool programs based on administrator and teacher perceptions. In-depth, semistructured phone interviews (n = 63) were conducted with administrators (n = 31) and teachers (n = 32) from North Carolina-based Head Start programs. Interviews were audio-recorded and transcribed verbatim. Data were analyzed qualitatively using content analysis to identify common themes. Five emergent themes were identified within the areas of NE resource availability and use and barriers to NE resource availability and use. Participants expressed desire for greater organization of existing NE material resources, increased community support, and professional development opportunities for teachers specific to NE. Funding and time constraints were reported as affecting NE resources. Creative strategies for addressing NE resource availability and use and barriers (eg, NE integration with educational standards) in Head Start are needed.

    Sintef Energy Research was engaged by NVE to evaluate the official requirements on voltage leaps in regulations concerning quality of delivery, and simultaneously conduct tests with a panel of test persons in order to get more detailed evaluations and recommendations to the existing requirements on voltage leaps. Tests and laboratory experiments have been performed on a total of 96 test persons, and the results reveal that voltage leaps even smaller than the 3 percent limit set by Norwegian regulations are visible to most people. The majority of the test persons consider the light conditions as unacceptably bad when light conditions are near the limit of voltage leap. Moreover, 25 percent of the test persons considered the light quality unacceptable when the voltage leap was well under half of the official limit.The results of the experiments indicates a need for narrowing the restrictions on voltage leaps in the Norwegian power network in order to limit the size and frequency of this kind of disturbance in the voltage. Recommendations for regulations are elaborated in chapter 3 (ml)

    Mediational intervention for sensitizing caregivers (MISC) is a structured program enabling caregivers to enhance their child's cognitive and emotional development through daily interactions. The principal aim was to evaluate if a year-long MISC caregiver training program produced greater improvement in child cognitive and emotional development compared with a control program. One hundred and nineteen uninfected HIV-exposed preschool children and their caregivers were randomly assigned to 1 of 2 treatment arms: biweekly MISC training alternating between home and clinic for 1 year or a health and nutrition curriculum. All children were evaluated at baseline, 6 months, and 1 year with the Mullen Early Learning Scales, Color-Object Association Test for memory, and Achenbach Child Behavior Checklist for psychiatric symptoms. Caregivers were evaluated on the same schedule with the Hopkins Symptoms Checklist-25 for depression and anxiety. The treatment arms were compared using repeated-measures analysis of covariance with child age, gender, weight, socioeconomic status, caregiving quality, caregiver anxiety, and caregiver education as covariates. The MISC children had significantly greater gains compared to controls on the Mullen Receptive and Expressive Language development, and on the Mullen composite score of cognitive ability. Color-Object Association Test total memory for MISC children was marginally better than controls. No Achenbach Child Behavior Checklist differences between the groups were noted. Caldwell Home Observation for Measurement of the Environment scores and observed mediational interaction scores from videotapes measuring caregiving quality also improved significantly more for the MISC group. The MISC enhanced cognitive performance, especially in language development. These benefits were possibly mediated by improved caregiving and positive emotional benefit to the caregiver.

    Full Text Available Home environment is key to the development of obesity-preventing behaviors during childhood, yet few resources help preschool parents address factors at home associated with obesity risk. This paper describes creation of materials for an in-home intervention (HomeStyles with this population. An advisory group of stakeholders and target audience members determined salient factors affecting childhood obesity to address in-home and developed program materials. The Social Cognitive Theory, Faith’s Core Behavior Change Strategies to Treat Childhood Obesity, Adult Learning Theory and motivational interviewing techniques guided development of 12 guides targeting strategies parents can use to shape the home environment. Interviews were conducted to determine effectiveness of the guides. Cognitive testing of guide design (n = 251 and content (n = 261 occurred in English and Spanish in New Jersey and Arizona with parents and home visitation staff who would present the guides. Interviews investigated perceptions of content usefulness and parent comprehension. Findings were also examined in light of theoretical underpinnings. Both home visitation staff and parents felt the guides were very readable and useful. Parents appreciated use of motivational interviewing techniques and Adult Learning Theory. Current research is testing these guides through an in-home, randomized control trial.

    The prevalence of obesity in the United States is a significant public health problem. Many obesity-related risk factors are more prevalent in minority populations. Given the recalcitrant nature of weight loss interventions for adults, prevention of overweight and obesity has become a high priority. The present study reports baseline data from an obesity prevention intervention developed for minority preschool children. Hip-Hop to Health Jr. is a 5-year randomized controlled intervention that targets 3- to 5-year-old minority children enrolled in 24 Head Start programs. Our primary aim is to test the effect of the intervention on change in body mass index. Data were collected on sociodemographic, anthropometric, behavioral, and cognitive variables for the children and parents at baseline. Participants included 416 black children, 337 black parents, 362 Latino children, and 309 Latino parents. Using body mass index for age and sex > or = the 95th percentile as the definition of overweight, 15% of the black children and 28% of the Latino children were overweight. More than 75% of the parents were either overweight or obese. The development of interventions to effectively prevent or control obesity early in life is crucial. These data highlight the escalating problem of weight control in minority populations.

  16. New "Tau-Leap" Strategy for Accelerated Stochastic Simulation.

    2014-12-10

    The "Tau-Leap" strategy for stochastic simulations of chemical reaction systems due to Gillespie and co-workers has had considerable impact on various applications. This strategy is reexamined with Chebyshev's inequality for random variables as it provides a rigorous probabilistic basis for a measured τ-leap thus adding significantly to simulation efficiency. It is also shown that existing strategies for simulation times have no probabilistic assurance that they satisfy the τ-leap criterion while the use of Chebyshev's inequality leads to a specified degree of certainty with which the τ-leap criterion is satisfied. This reduces the loss of sample paths which do not comply with the τ-leap criterion. The performance of the present algorithm is assessed, with respect to one discussed by Cao et al. ( J. Chem. Phys. 2006 , 124 , 044109), a second pertaining to binomial leap (Tian and Burrage J. Chem. Phys. 2004 , 121 , 10356; Chatterjee et al. J. Chem. Phys. 2005 , 122 , 024112; Peng et al. J. Chem. Phys. 2007 , 126 , 224109), and a third regarding the midpoint Poisson leap (Peng et al., 2007; Gillespie J. Chem. Phys. 2001 , 115 , 1716). The performance assessment is made by estimating the error in the histogram measured against that obtained with the so-called stochastic simulation algorithm. It is shown that the current algorithm displays notably less histogram error than its predecessor for a fixed computation time and, conversely, less computation time for a fixed accuracy. This computational advantage is an asset in repetitive calculations essential for modeling stochastic systems. The importance of stochastic simulations is derived from diverse areas of application in physical and biological sciences, process systems, and economics, etc. Computational improvements such as those reported herein are therefore of considerable significance.

  20. Neural Network Analysis of LEAP Energy Spectra

    Energy Technology Data Exchange (ETDEWEB)

    Holdridge, Robert E

    2002-09-10

    The Laser Electron Acceleration Project (LEAP) group has been conducting a proof of principle experiment on the acceleration of electrons with a pair of crossed laser beams. To date there has been no experimental verification of electron acceleration with crossed laser beams in a dielectric loaded vacuum, although the energy profile of an accelerated electron bunch has been well described by theory. The experiment is subject to unavoidable time dependent fluctuations in the independent variables. Changes in the experimental parameters can dramatically alter the beam profile incident near the focal plane of a high-resolution spectrometer located downstream from the accelerator cell. Neural networks (NNs) appear to provide an ideal tool for the positive determination of an acceleration event, being adaptable and able to handle highly complex nonlinear problems. Typical NNs under such conditions require a training set consisting of a representative data set along with ''answers'' which have been determined to be consistent with the variable state of the experimental parameters. A strategy of pattern recognition with respect to the status of independent variables can be employed to determine the signature characteristics of a laser perturbed electron bunch. Data cuts representing characteristics that were thought to be distinctive to accelerated beam profile images were implemented in the algorithm employed. Statistical analysis of the results of data cuts made on the energy profile images from the experiment is presented, as well as conclusions drawn from the results of this analysis. Finally, a discussion of future directions to be taken in this work is given including the orientation towards on-line, real-time analysis.

    For children with low self-regulation in the preschool years, the likelihood of poorer intellectual, health, wealth and anti-social outcomes in adulthood is overwhelming. Yet this knowledge has not yielded a framework for understanding self-regulatory change, nor generated particularly successful methods for enacting this change. Reconciling insights from cross-disciplinary theory, research and practice, this study seeks to implement a newly developed program of low-cost and routine practices and activities for supporting early self-regulatory development within preschool contexts and to evaluate its effect on children's self-regulation, executive function and school readiness; and educator perceived knowledge, attitudes and self-efficacy related to self-regulation. The Early Start to Self-Regulation study is a cluster randomized, controlled trial for evaluating benefits of the Preschool Situational Self-Regulation Toolkit (PRSIST) program, when implemented by early childhood educators, compared with routine practice. The PRSIST program combines professional learning, adult practices, child activities and connections to the home to support children's self-regulation development. Fifty preschool centers in New South Wales, Australia, will be selected to ensure a range of characteristics, namely: National Quality Standards (NQS) ratings, geographic location and socioeconomic status. After collection of baseline child and educator data, participating centers will then be randomly allocated to one of two groups, stratified by NQS rating: (1) an intervention group (25 centers) that will implement the PRSIST program; or (2) a control group (25 centers) that will continue to engage in practice as usual. Primary outcomes at the child level will be two measures of self-regulation: Head-Toes-Knees-Shoulders task and the PRSIST observational assessment. Secondary outcomes at the child level will be adult-reported measures of child self-regulation, executive function and

    Full Text Available The purpose of this paper is to present the results of two online forums carried out with the participation of 42 students of the Licenciaturas  in Preschool Education, Primary Education and Secondary Education of the University of Costa Rica. The main purpose of the forums was to determine the insights of the participant students about the competencies they have achieved in the field of education research, and which have been the essential tools for them to systematize their own teaching practices. The discussion forums were part of the course FD5091 Métodos de Investigación Educativa [Education Research Methods] of the School of Teacher Education, delivered from March-April 2010.  Of the sample, 60 percent were students of the Preschool teaching program, 35 percent were from the Primary Education teaching program and 5 percent were from the Secondary Education teaching program in the fields of Science, Mathematics and Social Studies. According to the insights and beliefs showed by the participants –both, the future teachers and the profession practitioners–, there are no opportunities for research or systematization of their own teaching mediation, in the current work situation. (1 Translator’s Note: In Costa Rica, the “Licenciatura” is a one-year post-Bachelor study program, usually including thesis. “Primary Education” refers to students from the 1st to 6th grades, and “Secondary Education” refers to students from the 7th to 11th grades.

    Self-regulatory skills are broadly defined as the ability to manage emotions, focus attention, and inhibit some behaviors while activating others in accordance with social expectations and are an established indicator of academic success. Growing evidence links motor skills and physical activity to self-regulation. This study examined the efficacy of a motor skills intervention (i.e., the Children's Health Activity Motor Program, CHAMP) that is theoretically grounded in Achievement Goal Theory on motor skill performance and self-regulation in Head Start preschoolers. A sample of 113 Head Start preschoolers (Mage = 51.91 ± 6.5 months; 49.5% males) were randomly assigned to a treatment (n = 68) or control (n = 45) program. CHAMP participants engaged in 15, 40-min sessions of a mastery climate intervention that focused on the development of motor skills over 5 weeks while control participants engaged in their normal outdoor recess period. The Delay of Gratification Snack Task was used to measure self-regulation and the Test of Gross Motor Development-2nd Edition was used to assess motor skills. All measures were assessed prior to and following the intervention. Linear mixed models were fit for both self-regulation and motor skills. Results revealed a significant time × treatment interaction (p motor skills, post hoc comparisons found that all children improved their motor skills (p skills associated with healthy development in children (i.e., motor skills and self-regulation).

    Single nucleotide polymorphism (SNP) high-dimensional datasets are available from Genome Wide Association Studies (GWAS). Such data provide researchers opportunities to investigate the complex genetic basis of diseases. Much of genetic risk might be due to undiscovered epistatic interactions, which are interactions in which combination of several genes affect disease. Research aimed at discovering interacting SNPs from GWAS datasets proceeded in two directions. First, tools were developed to evaluate candidate interactions. Second, algorithms were developed to search over the space of candidate interactions. Another problem when learning interacting SNPs, which has not received much attention, is evaluating how likely it is that the learned SNPs are associated with the disease. A complete system should provide this information as well. We develop such a system. Our system, called LEAP, includes a new heuristic search algorithm for learning interacting SNPs, and a Bayesian network based algorithm for computing the probability of their association. We evaluated the performance of LEAP using 100 1,000-SNP simulated datasets, each of which contains 15 SNPs involved in interactions. When learning interacting SNPs from these datasets, LEAP outperformed seven others methods. Furthermore, only SNPs involved in interactions were found to be probable. We also used LEAP to analyze real Alzheimer's disease and breast cancer GWAS datasets. We obtained interesting and new results from the Alzheimer's dataset, but limited results from the breast cancer dataset. We conclude that our results support that LEAP is a useful tool for extracting candidate interacting SNPs from high-dimensional datasets and determining their probability. © 2015 The Authors. *Genetic Epidemiology published by Wiley Periodicals, Inc.

    2014-01-01

    Background Refractive error is defined as the inability of the eye to bring parallel rays of light into focus on the retina, resulting in nearsightedness (myopia), farsightedness (Hyperopia) or astigmatism. Uncorrected refractive error in children is associated with increased morbidity and reduced educational opportunities. Vision screening (VS) is a method for identifying children with visual impairment or eye conditions likely to lead to visual impairment. Objective To analyze the utility of vision screening conducted by teachers and to contribute to a better estimation of the prevalence of childhood refractive errors in Apurimac, Peru. Design A pilot vision screening program in preschool (Group I) and elementary school children (Group II) was conducted with the participation of 26 trained teachers. Children whose visual acuity was<6/9 [20/30] (Group I) and≤6/9 (Group II) in one or both eyes, measured with the Snellen Tumbling E chart at 6 m, were referred for a comprehensive eye exam. Specificity and positive predictive value to detect refractive error were calculated against clinical examination. Program assessment with participants was conducted to evaluate outcomes and procedures. Results A total sample of 364 children aged 3–11 were screened; 45 children were examined at Centro Oftalmológico Monseñor Enrique Pelach (COMEP) Eye Hospital. Prevalence of refractive error was 6.2% (Group I) and 6.9% (Group II); specificity of teacher vision screening was 95.8% and 93.0%, while positive predictive value was 59.1% and 47.8% for each group, respectively. Aspects highlighted to improve the program included extending training, increasing parental involvement, and helping referred children to attend the hospital. Conclusion Prevalence of refractive error in children is significant in the region. Vision screening performed by trained teachers is a valid intervention for early detection of refractive error, including screening of preschool children. Program

    Exposure to adverse childhood experiences (ACE) has been found to have a profound negative impact on multiple child outcomes, including academic achievement, social cognition patterns, and behavioral adjustment. However, these links have yet to be examined in preschool children that are already experiencing behavior or social-emotional problems. Thus, the present study examined the links between the caregiver's and the child's exposure to ACE and multiple child and caregiver's outcomes in a sample of 30 preschool children enrolled in a Therapeutic Nursery Program (TNP). Children are typically referred to this TNP due to significant delays in their social emotional development that often result in difficulty functioning in typical childcare, home, and community settings. Analyses revealed some contradictory patterns that may be specific to this clinical sample. Children with higher exposure to ACE showed more biased social information processing patterns and their caregivers reported lower child social skills than caregivers of children with less exposure, however their inhibitory control levels were higher (better control) and staff reported that these children exhibited better social skills as well as better approaches to learning than children with less exposure. No such contradictions were found in relation to the caregiver's exposure to ACE, as it was positively associated with a number of negative child and caregiver outcomes.

    Full Text Available Background Recently, parenting programs to address behavioural and emotional problems associated with child maltreatment in developing countries have received much attention. There is a paucity of literature on effective parent education interventions in the local context of Pakistan. This study aimed to assess the feasibility of offering a 6-week parenting program for mothers of pre-school children attending family health centres (FHCs in Karachi, the largest metropolitan city of Pakistan. Methods A pilot quasi-experimental trial was conducted. Two FHCs were selected, one as the intervention and the second as the control. A total of 57 mothers of pre-school children (n = 30 intervention; n = 27 control participated in this study. Mothers in the intervention group received SOS Help for parents module, while mothers in the control group received information about routine childcare. A parenting scale (PS was administered before the program was implemented and repeated 2 weeks after the program was completed in both groups. Statistical analysis was performed to compare participants’ attributes. Descriptive analysis was conducted to compare pre- and post-test mean scores along with standard deviation for parenting subscales in the intervention and control groups. Results A total of 50 mothers (n = 25 intervention; n = 25 control completed the 6-week program. Attrition was observed as 5/30 (17% in the intervention arm and 2/27 (2% in the control arm. Mothers commonly reported the burden of daily domestic and social responsibilities as the main reason for dropping out. Furthermore, the majority of participants in the control group recommended increasing the duration of weekly sessions from 1 to 1.5 hours, thereby decreasing the program period from 6 to 4 weeks. Mothers in intervention group reported substantial improvement in parenting skills as indicated by mean difference in their pre- and post-test scores for laxness and over

  6. Leap Motion Device Used to Control a Real Anthropomorphic Gripper

    Full Text Available This paper presents for the first time the use of the Leap Motion device to control an anthropomorphic gripper with five fingers. First, a description of the Leap Motion device is presented, highlighting its main functional characteristics, followed by testing of its use for capturing the movements of a human hand's fingers in different configurations. Next, the HandCommander soft module and the Interface Controller application are described. The HandCommander is a software module created to facilitate interaction between a human hand and the GraspIT virtual environment, and the Interface Controller application is required to send motion data to the virtual environment and to test the communication protocol. For the test, a prototype of an anthropomorphic gripper with five fingers was made, including a proper hardware system of command and control, which is briefly presented in this paper. Following the creation of the prototype, the command system performance test was conducted under real conditions, evaluating the recognition efficiency of the objects to be gripped and the efficiency of the command and control strategies for the gripping process. The gripping test is exemplified by the gripping of an object, such as a screw spanner. It was found that the command system, both in terms of capturing human hand gestures with the Leap Motion device and effective object gripping, is operational. Suggestive figures are presented as examples.

  7. Avoiding negative populations in explicit Poisson tau-leaping.

    Cao, Yang; Gillespie, Daniel T; Petzold, Linda R

    2005-08-01

    The explicit tau-leaping procedure attempts to speed up the stochastic simulation of a chemically reacting system by approximating the number of firings of each reaction channel during a chosen time increment tau as a Poisson random variable. Since the Poisson random variable can have arbitrarily large sample values, there is always the possibility that this procedure will cause one or more reaction channels to fire so many times during tau that the population of some reactant species will be driven negative. Two recent papers have shown how that unacceptable occurrence can be avoided by replacing the Poisson random variables with binomial random variables, whose values are naturally bounded. This paper describes a modified Poisson tau-leaping procedure that also avoids negative populations, but is easier to implement than the binomial procedure. The new Poisson procedure also introduces a second control parameter, whose value essentially dials the procedure from the original Poisson tau-leaping at one extreme to the exact stochastic simulation algorithm at the other; therefore, the modified Poisson procedure will generally be more accurate than the original Poisson procedure.

    Preschoolers with attention-deficit/hyperactivity disorder (ADHD) have been found to exhibit impairments on neuropsychological measures of working memory (WM). As WM is an important predictor of future learning abilities, early intervention could help to prevent severe problems. The purpose of this research was to ascertain the efficacy of an intervention for training WM in 5-year-old children with symptoms of ADHD. Thirty-four children with symptoms of ADHD were randomly divided into two groups: One was assigned to the WM training condition, and the other continued normal class activities. The training was provided at school in small groups that also included typically developing children. The trained group showed a significant improvement in tasks measuring their WM and other controlled processes at conclusion of study, whereas no significant improvement was found in the control group. We concluded that early intervention on WM may be effective in children with symptoms of ADHD.

    An empirical criterion is formulated to describe the compressive strength of the densely welded Apache Leap tuff. The criterion incorporates the effects of size, L/D ratio, loading rate and density variations. The criterion improves the correlation between the test results and the failure envelope. Uniaxial and triaxial compressive strengths, Brazilian tensile strength and elastic properties of the densely welded brown unit of the Apache Leap tuff have been determined using the ASTM standard test methods. All tuff samples are tested dry at room temperature (22 ± 2 degrees C), and have the core axis normal to the flow layers. The uniaxial compressive strength is 73.2 ± 16.5 MPa. The Brazilian tensile strength is 5.12 ± 1.2 MPa. The Young's modulus and Poisson's ratio are 22.6 ± 5.7 GPa and 0.20 ± 0.03. Smoothness and perpendicularity do not fully meet the ASTM requirements for all samples, due to the presence of voids and inclusions on the sample surfaces and the sample preparation methods. The investigations of loading rate, L/D radio and cyclic loading effects on the compressive strength and of the size effect on the tensile strength are not conclusive. The Coulomb strength criterion adequately represents the failure envelope of the tuff under confining pressures from 0 to 62 MPa. Cohesion and internal friction angle are 16 MPa and 43 degrees. The brown unit of the Apache Leap tuff is highly heterogeneous as suggested by large variations of the test results. The high intrinsic variability of the tuff is probably caused by the presence of flow layers and by nonuniform distributions of inclusions, voids and degree of welding. Similar variability of the properties has been found in publications on the Topopah Spring tuff at Yucca Mountain. 57 refs., 32 figs., 29 tabs

    The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in the United States provides free supplemental food and nutrition education to low-income mothers and children under age 5 years. Childhood obesity prevalence is higher among preschool children in the WIC program compared to other children, and WIC improves dietary quality among low-income children. The Children Eating Well (CHEW) smartphone app was developed in English and Spanish for WIC-participating families with preschool-aged children as a home-based intervention to reinforce WIC nutrition education and help prevent childhood obesity. This paper describes the development and beta-testing of the CHEW smartphone app. The objective of beta-testing was to test the CHEW app prototype with target users, focusing on usage, usability, and perceived barriers and benefits of the app. The goals of the CHEW app were to make the WIC shopping experience easier, maximize WIC benefit redemption, and improve parent snack feeding practices. The CHEW app prototype consisted of WIC Shopping Tools, including a barcode scanner and calculator tools for the cash value voucher for purchasing fruits and vegetables, and nutrition education focused on healthy snacks and beverages, including a Yummy Snack Gallery and Healthy Snacking Tips. Mothers of 63 black and Hispanic WIC-participating children ages 2 to 4 years tested the CHEW app prototype for 3 months and completed follow-up interviews. Study participants testing the app for 3 months used the app on average once a week for approximately 4 and a half minutes per session, although substantial variation was observed. Usage of specific features averaged at 1 to 2 times per month for shopping-related activities and 2 to 4 times per month for the snack gallery. Mothers classified as users rated the app's WIC Shopping Tools relatively high on usability and benefits, although variation in scores and qualitative feedback highlighted several barriers that

    To conduct a process and impact evaluation of a multifaceted education-based pilot program targeting correct use of age-appropriate restraints in a regional setting with a high proportion of Aboriginal and Torres Strait Islander families. The program was delivered in 2010 in 3 early learning centers where 31 percent of the children were of Aboriginal and Torres Strait Islander descent. Each component of the program was assessed for message consistency and uptake. To measure program effectiveness, participating children were matched 1:1 by age, language spoken at home, and annual household income with 71 children from the control arm of a contemporaneous trial. The outcome measure in the control and program centers (a 4-category ordinal scale of restraint use) was compared using ordinal logistic regression accounting for age of the parent. Process evaluation found that though program components were delivered with a consistency of message, uptake was affected by turnover of all staff at one center and by parents experiencing difficulty in paying for subsidized restraints at each of the centers. Impact evaluation found that children from the centers receiving the program had nearly twice the odds of being in a better restraint category than children matched from the control group (adjusted odds ratio [ORadj] = 2.06, 95% confidence interval [CI], 1.09-3.90). This was a pragmatic study reflecting the real-life issues of implementing a program in preschools where 57 percent of families had a low income and turnover of staff was high. Despite these issues, impact evaluation showed that the integrated educational program showed promise in increasing correct use of age-appropriate restraints. The findings from this pilot study support the use of an integrated educational program that includes access to subsidized restraints to promote best practice child restraint use among communities that include a high proportion of Aboriginal and Torres Strait Islander families in New

  2. The Traditional in Contemporary Curricula of Preschool Education

    2016-02-01

    Full Text Available Contemporary curricula of preschool education are the result of the improvement of pedagogical and didactic theories. They imply a technical plan with which it is possible to achieve measurable objectives of preschool education. The curriculum is also defined as a tool for quality and equal education for all. It represents a reflection of the time, society and culture in which it exists, but also a model for future society and education. Thus an important research question arises as to what extent we recognize traditional ideas about learning and the development of a preschool child in contemporary preschool programs. Are traditional ideas about educating young children unjustly neglected or do we recognize them in contemporary pedagogical theory even today, at the same time forgetting about the past and declaring them innovations? This paper deals with the starting points for the development of a curriculum. The goal of the research was to determine to what extent can the starting points for the development of preschool children, which have existed in the first preschool programs in Serbia in the late 19th century, be recognized in contemporary preschool programs. A descriptive method was applied as well as a procedure for content analysis of program documents. Research results confirm that the elements of the first preschool programs, which remain relevant until today, can be recognized in contemporary preschool programs. They are related to target orientations, principles and functions of preschool education. However, these ideas are defined as contemporary tendencies, and the fact that they existed in preschool programs that were developed a long time ago is unjustly ignored.

  3. Multilevel hybrid split-step implicit tau-leap

    In biochemically reactive systems with small copy numbers of one or more reactant molecules, the dynamics is dominated by stochastic effects. To approximate those systems, discrete state-space and stochastic simulation approaches have been shown to be more relevant than continuous state-space and deterministic ones. In systems characterized by having simultaneously fast and slow timescales, existing discrete space-state stochastic path simulation methods, such as the stochastic simulation algorithm (SSA) and the explicit tau-leap (explicit-TL) method, can be very slow. Implicit approximations have been developed to improve numerical stability and provide efficient simulation algorithms for those systems. Here, we propose an efficient Multilevel Monte Carlo (MLMC) method in the spirit of the work by Anderson and Higham (SIAM Multiscal Model. Simul. 10(1), 2012). This method uses split-step implicit tau-leap (SSI-TL) at levels where the explicit-TL method is not applicable due to numerical stability issues. We present numerical examples that illustrate the performance of the proposed method. © 2016 Springer Science+Business Media New York

    To evaluate mediational intervention for sensitizing caregivers (MISC). MISC biweekly caregiver training significantly enhanced child development compared with biweekly training on health and nutrition (active control) and to evaluate whether MISC training improved the emotional well-being of the caregivers compared with controls. Sixty of 120 rural Ugandan preschool child/caregiver dyads with HIV were assigned by randomized clusters to biweekly MISC training, alternating between home and clinic for 1 year. Control dyads received a health and nutrition curriculum. Children were evaluated at baseline, 6 months, and 1 year with the Mullen Early Learning Scales and the Color-Object Association Test for memory. Caldwell Home Observation for Measurement of the Environment and videotaped child/caregiver MISC interactions also were evaluated. Caregivers were evaluated for depression and anxiety with the Hopkins Symptoms Checklist. Between-group repeated-measures ANCOVA comparisons were made with age, sex, CD4 levels, viral load, material socioeconomic status, physical development, and highly active anti-retroviral therapy treatment status as covariates. The children given MISC had significantly greater gains compared with controls on the Mullen Visual Reception scale (visual-spatial memory) and on Color-Object Association Test memory. MISC caregivers significantly improved on Caldwell Home Observation for Measurement of the Environment scale and total frequency of MISC videotaped interactions. MISC caregivers also were less depressed. Mortality was less for children given MISC compared with controls during the training year. MISC was effective in teaching Ugandan caregivers to enhance their children's cognitive development through practical and sustainable techniques applied during daily interactions in the home.

    When a stream of shampoo is fed onto a pool in one\\'s hand, a jet can leap sideways or rebound from the liquid surface in an intriguing phenomenon known as the Kaye effect. Earlier studies have debated whether non-Newtonian effects are the underlying cause of this phenomenon, making the jet glide on top of a shear-thinning liquid layer, or whether an entrained air layer is responsible. Herein we show unambiguously that the jet slides on a lubricating air layer. We identify this layer by looking through the pool liquid and observing its rupture into fine bubbles. The resulting microbubble sizes suggest this air layer is of submicron thickness. This thickness estimate is also supported by the tangential deceleration of the jet during the rebounding.

    Corporal punishment is a widely used and widely endorsed form of parental discipline. Inter-partner violence places enormous stress upon women. The rate of corporal punishment is higher in homes where other types of domestic violence are also occurring. This study compares two groups: those who participated in an intervention for women exposed to intimate partner violence (The Moms' Empowerment Program [MEP]) and those in a comparison group. Using standardized measures, women in both groups were assessed at baseline and at the end of the program, 5 weeks later. The 113 mothers who participated in the MEP program had significantly improved their parenting, such that they had less use of physical punishment post-intervention. Findings suggest that a relatively brief community-based intervention program can reduce the use of parental physical punishment even in disadvantaged populations coping with stressful circumstances. © The Author(s) 2016.

    The Leap Motion controller is a low-cost, optically-based hand tracking system that has recently been introduced on the consumer market. Prior studies have investigated its precision and accuracy, toward evaluating its usefulness as a surgical robot master interface. Yet due to the diversity of potential slave robots and surgical procedures, as well as the dynamic nature of surgery, it is challenging to make general conclusions from published accuracy and precision data. Thus, our goal in this paper is to explore the use of the Leap in the specific scenario of endonasal pituitary surgery. We use it to control a concentric tube continuum robot in a phantom study, and compare user performance using the Leap to previously published results using the Phantom Omni. We find that the users were able to achieve nearly identical average resection percentage and overall surgical duration with the Leap.

  4. The leap from ROI to SROI: Farther than expected?

    Science.gov (United States)

    Gargani, John

    2017-10-01

    Social return on investment (SROI) is a popular method for evaluating the impact that organizations have on society and the environment. It has its roots in finance, where return on investment (ROI) is used to evaluate investments. Over the past ten years, SROI has made the leap from a tool for building private wealth to one that advances the public good. Has it landed us in a better place? To answer the question, I describe the general approach to financial analysis, how it is applied to financial decisions, and how it has been adapted to evaluate impact. I then consider the strengths and weaknesses of SROI, and suggest how, by pushing beyond the constraints of financial analysis, it can give stakeholders voice and provide evidence of success from diverse perspectives. Along the way, I propose a conceptual model for value, a foundational concept in SROI that has been criticized by some as underdeveloped, and I include a technical appendix that identifies potential sources of statistical bias in SROI estimates. I conclude by acknowledging our growing need to incorporate efficiency as one of multiple success criteria and the role that SROI-properly implemented-can play. Copyright © 2017 Elsevier Ltd.

  11. Drift-Implicit Multi-Level Monte Carlo Tau-Leap Methods for Stochastic Reaction Networks

    KAUST Repository

    Ben Hammouda, Chiheb

    2015-05-12

    In biochemical systems, stochastic e↵ects can be caused by the presence of small numbers of certain reactant molecules. In this setting, discrete state-space and stochastic simulation approaches were proved to be more relevant than continuous state-space and deterministic ones. These stochastic models constitute the theory of stochastic reaction networks (SRNs). Furthermore, in some cases, the dynamics of fast and slow time scales can be well separated and this is characterized by what is called sti↵ness. For such problems, the existing discrete space-state stochastic path simulation methods, such as the stochastic simulation algorithm (SSA) and the explicit tau-leap method, can be very slow. Therefore, implicit tau-leap approxima- tions were developed to improve the numerical stability and provide more e cient simulation algorithms for these systems. One of the interesting tasks for SRNs is to approximate the expected values of some observables of the process at a certain fixed time T. This is can be achieved using Monte Carlo (MC) techniques. However, in a recent work, Anderson and Higham in 2013, proposed a more computationally e cient method which combines multi-level Monte Carlo (MLMC) technique with explicit tau-leap schemes. In this MSc thesis, we propose new fast stochastic algorithm, particularly designed 5 to address sti↵ systems, for approximating the expected values of some observables of SRNs. In fact, we take advantage of the idea of MLMC techniques and drift-implicit tau-leap approximation to construct a drift-implicit MLMC tau-leap estimator. In addition to accurately estimating the expected values of a given observable of SRNs at a final time T , our proposed estimator ensures the numerical stability with a lower cost than the MLMC explicit tau-leap algorithm, for systems including simultane- ously fast and slow species. The key contribution of our work is the coupling of two drift-implicit tau-leap paths, which is the basic brick for

    The Leap Motion Controller is a new device for hand gesture controlled user interfaces with declared sub-millimeter accuracy. However, up to this point its capabilities in real environments have not been analyzed. Therefore, this paper presents a first study of a Leap Motion Controller. The main focus of attention is on the evaluation of the accuracy and repeatability. For an appropriate evaluation, a novel experimental setup was developed making use of an industrial robot with a reference pen allowing a position accuracy of 0.2 mm. Thereby, a deviation between a desired 3D position and the average measured positions below 0.2 mm has been obtained for static setups and of 1.2 mm for dynamic setups. Using the conclusion of this analysis can improve the development of applications for the Leap Motion controller in the field of Human-Computer Interaction.

    Early childhood is a critical period for the development of fundamental movement skills (FMS). Children who do not master FMS are more likely to experience failure in the motor domain and less likely to participate in sport and games during childhood and adolescence. Studies among primary school aged children report low levels of FMS mastery indicating the need to implement FMS programs during the preschool years. Cross-sectional study of 425 children attending preschools in the Sydney, Australia in 2008. FMS were assessed using the Test of Gross Motor Development-2 including locomotor (run, gallop, hop, horizontal jump) and object control (strike, catch, kick overhand throw) skills. Data were analysed using linear regression and chi-squared analyses. Total locomotor score was higher among girls compared with boys (pskills and boys had higher mastery of object control skills. These findings highlight the need to provide structured opportunities which facilitate children's acquisition of FMS, which may include providing gender separated games, equipment and spaces. That mastery of FMS is low in primary school children indicates the importance of early intervention programs in preschools. Preschools and child care centers hold promise as a key setting for implementing FMS programs.

  10. LEAP: A balloon-borne search for low-energy cosmic ray antiprotons

    Science.gov (United States)

    Moats, Anne Rosalie Myers

    The LEAP (Low Energy Antiproton) experiment is a search for cosmic ray antiprotons in the 120 MeV to 1.2 GeV kinetic energy range. The motivation for this project was the result announced by Buffington et al. (1981) that indicated an anomalously high antiproton flux below 300 MeV; this result has compelled theorists to propose sources of primary antiprotons above the small secondary antiproton flux produced by high energy cosmic ray collisions with nuclei in the interstellar medium. LEAP consisted of the NMSU magnet spectrometer, a time-of-flight system designed at NASA-Goddard, two scintillation detectors, and a Cherenkov counter. Analysis of flight data performed by the high energy astrophysics group at Goddard Space Flight Center revealed no antiproton candidates found in the 120 MeV to 360 MeV range; 3 possible antiproton candidate events were found in the 500 MeV to 1.2 GeV range in an analysis done here at the University of Arizona. However, since it will be necessary to sharpen the calibration on all of the LEAP systems in order to positively identify these events as antiprotons, only an upper limit has been determined at present. Thus, combining the analyses performed at the University of Arizona and NASA-Goddard, 90 percent confidence upper limits of 3.5 x 10-5 in the 120 MeV to 360 MeV range and 2.3 x 10-4 in the 500 MeV to 1.2 GeV range for the antiproton/proton ratio is indicated by the LEAP results. LEAP disagrees sharply with the results of the Buffington group, indicating a low antiproton flux at these energies. Thus, a purely secondary antiproton flux may be adequate at low energies.

    2014-01-01

    Research findings The present study observed and coded instruction in 65 preschool classrooms to examine (a) overall amounts and (b) types of mathematics and science learning opportunities experienced by preschool children as well as (c) the extent to which these opportunities were associated with classroom and program characteristics. Results indicated that children were afforded an average of 24 and 26 minutes of mathematics and science learning opportunities, respectively, corresponding to spending approximately 25% of total instructional time in each domain. Considerable variability existed, however, in the amounts and types of mathematics and science opportunities provided to children in their classrooms; to some extent, this variability was associated with teachers’ years of experience, teachers’ levels of education, and the socioeconomic status of children served in the program. Practice/policy Although results suggest greater integration of mathematics and science in preschool classrooms than previously established, there was considerable diversity in the amounts and types of learning opportunities provided in preschool classrooms. Affording mathematics and science experiences to all preschool children, as outlined in professional and state standards, may require additional professional development aimed at increasing preschool teachers’ understanding and implementation of learning opportunities in these two domains in their classrooms.

    Quality preschool programs that develop the whole child through age-appropriate socioemotional and cognitive skill-building hold promise for significantly improving child outcomes. However, preschool programs tend to either be teacher-led and didactic, or else to lack academic content. One preschool model that involves both child-directed, freely chosen activity and academic content is Montessori. Here we report a longitudinal study that took advantage of randomized lottery-based admission to two public Montessori magnet schools in a high-poverty American city. The final sample included 141 children, 70 in Montessori and 71 in other schools, most of whom were tested 4 times over 3 years, from the first semester to the end of preschool (ages 3-6), on a variety of cognitive and socio-emotional measures. Montessori preschool elevated children's outcomes in several ways. Although not different at the first test point, over time the Montessori children fared better on measures of academic achievement, social understanding, and mastery orientation, and they also reported relatively more liking of scholastic tasks. They also scored higher on executive function when they were 4. In addition to elevating overall performance on these measures, Montessori preschool also equalized outcomes among subgroups that typically have unequal outcomes. First, the difference in academic achievement between lower income Montessori and higher income conventionally schooled children was smaller at each time point, and was not (statistically speaking) significantly different at the end of the study. Second, defying the typical finding that executive function predicts academic achievement, in Montessori classrooms children with lower executive function scored as well on academic achievement as those with higher executive function. This suggests that Montessori preschool has potential to elevate and equalize important outcomes, and a larger study of public Montessori preschools is warranted.

    Full Text Available Optimization of hole-making operations in manufacturing industry plays a vital role. Tool travel and tool switch planning are the two major issues in hole-making operations. Many industrial applications such as moulds, dies, engine block, automotive parts etc. requires machining of large number of holes. Large number of machining operations like drilling, enlargement or tapping/reaming are required to achieve the final size of individual hole, which gives rise to number of possible sequences to complete hole-making operations on the part depending upon the location of hole and tool sequence to be followed. It is necessary to find the optimal sequence of operations which minimizes the total processing cost of hole-making operations. In this work, therefore an attempt is made to reduce the total processing cost of hole-making operations by applying relatively new optimization algorithms known as shuffled frog leaping algorithm and proposed modified shuffled frog leaping algorithm for the determination of optimal sequence of hole-making operations. An industrial application example of ejector plate of injection mould is considered in this work to demonstrate the proposed approach. The obtained results by the shuffled frog leaping algorithm and proposed modified shuffled frog leaping algorithm are compared with each other. It is seen from the obtained results that the results of proposed modified shuffled frog leaping algorithm are superior to those obtained using shuffled frog leaping algorithm.

  6. Towards automatic global error control: Computable weak error expansion for the tau-leap method

    KAUST Repository

    Karlsson, Peer Jesper; Tempone, Raul

    2011-01-01

    This work develops novel error expansions with computable leading order terms for the global weak error in the tau-leap discretization of pure jump processes arising in kinetic Monte Carlo models. Accurate computable a posteriori error approximations are the basis for adaptive algorithms, a fundamental tool for numerical simulation of both deterministic and stochastic dynamical systems. These pure jump processes are simulated either by the tau-leap method, or by exact simulation, also referred to as dynamic Monte Carlo, the Gillespie Algorithm or the Stochastic Simulation Slgorithm. Two types of estimates are presented: an a priori estimate for the relative error that gives a comparison between the work for the two methods depending on the propensity regime, and an a posteriori estimate with computable leading order term. © de Gruyter 2011.

    Full Text Available Natural User Interfaces (NUI is a relatively new area of research that aims to develop humancomputer interfaces, natural and intuitive, using voice commands, hand movements and gesture recognition, similar to communication between people which also implies body language and gestures. In this paper is presented a natural designed workspace which acquires the user's motion using a Leap Motion sensor and visualizes the CAD models using a CAVE-like 3D visualisation system. The user can modify complex CAD models using bimanual gesture commands in a 3D virtual environment. The developed bimanual gestures for rotate, pan, zoom and explode are presented. From the conducted experiments is established that Leap Motion NUI sensor provides an intuitive tool for design review of CAD models, performed even by users with no experience in CAD systems and virtual environments.

    Leaping out of water is a phenomenon exhibited by a variety of aquatic and semi-aquatic animals, such as frogs and whales. In this study, we aim to elucidate the effects of geometric and kinematic conditions on the propulsive and drag force required for an animal to jump through the water interface. A simple mechanism was designed to measure the propulsive thrust produced by a flapping appendage. In a separate experiment to measure the opposing drag, simplified models of animals are 3D printed and fitted with pressure sensors. The model is accelerated from rest and covers a range of Re from 103 to 105. Using a high-speed camera and pressure sensors, we observed a deformation of the free surface prior to water exit, and correlated this to the drag force. Finally, we discuss a scaling law to describe the general physics which allow animals to leap out of water. NSF EAPSI.

    2018-01-01

    We announce barycorrpy (BCPy) , a Python implementation to calculate precise barycentric corrections well below the 1 cm/s level, following the algorithm of Wright and Eastman (2014). This level of precision is required in the search for 1 Earth mass planets in the Habitable Zones of Sun-like stars by the Radial Velocity (RV) method, where the maximum semi-amplitude is about 9 cm/s. We have developed BCPy to be used in the pipeline for the next generation Doppler Spectrometers - Habitable-zone Planet Finder (HPF) and NEID. In this work, we also develop an automated leap second management routine to improve upon the one available in Astropy. It checks for and downloads a new leap second file before converting from the UT time scale to TDB.

    2012-01-01

    In the past two decades, there has been an increased interest in the assessment and treatment of preschool children presenting with concerns about attention problems. This article reviews the research and clinical literature involving assessment of attention and related skills in the preschool years. While inattention among preschoolers is common, symptoms alone do not necessarily indicate a disorder, and most often represent a normal variation in typical preschool child development. Thus, accurate identification of “disordered” attention in preschoolers can be challenging, and development of appropriate, norm-referenced tests of attention for preschoolers is also difficult. The current review suggests that comprehensive assessment of attention and related functions in the preschool child should include thorough review of the child’s history, planned observations, and formal psychometric testing. The three primary methods of psychometric assessment that have been used to characterize attentional functioning in preschool children include performance-based tests, structured caregiver interviews, and rating scales (parent, teacher, and clinician). Among performance-based methods for measurement of attention in the preschool years, tests have been developed to assess sustained attention, selective (focused) attention, span of attention (encoding/manipulation), and (top-down) controlled attention—including freedom from distractibility and set shifting. Many of these tests remain experimental in nature, and review of published methods yields relatively few commercially available, nationally normed tests of attention for preschoolers, and an overall dearth of reliability and validity studies on the available measures.

  16. SparseLeap: Efficient Empty Space Skipping for Large-Scale Volume Rendering

    KAUST Repository

    Hadwiger, Markus

    2017-08-28

    Recent advances in data acquisition produce volume data of very high resolution and large size, such as terabyte-sized microscopy volumes. These data often contain many fine and intricate structures, which pose huge challenges for volume rendering, and make it particularly important to efficiently skip empty space. This paper addresses two major challenges: (1) The complexity of large volumes containing fine structures often leads to highly fragmented space subdivisions that make empty regions hard to skip efficiently. (2) The classification of space into empty and non-empty regions changes frequently, because the user or the evaluation of an interactive query activate a different set of objects, which makes it unfeasible to pre-compute a well-adapted space subdivision. We describe the novel SparseLeap method for efficient empty space skipping in very large volumes, even around fine structures. The main performance characteristic of SparseLeap is that it moves the major cost of empty space skipping out of the ray-casting stage. We achieve this via a hybrid strategy that balances the computational load between determining empty ray segments in a rasterization (object-order) stage, and sampling non-empty volume data in the ray-casting (image-order) stage. Before ray-casting, we exploit the fast hardware rasterization of GPUs to create a ray segment list for each pixel, which identifies non-empty regions along the ray. The ray-casting stage then leaps over empty space without hierarchy traversal. Ray segment lists are created by rasterizing a set of fine-grained, view-independent bounding boxes. Frame coherence is exploited by re-using the same bounding boxes unless the set of active objects changes. We show that SparseLeap scales better to large, sparse data than standard octree empty space skipping.

    Regular physical activity (PA) and the avoidance of prolonged sitting are essential for children's healthy growth, and for the physical and mental wellbeing of both children and adults. In the context of exercise, music may promote behavioral change through increased exercise adherence and participation. The purpose of this study was to determine whether a movement-to-music video program could reduce sedentary behavior (SB) and increase PA in mother-child pairs in the home environment. A randomized controlled trial was conducted in the Pirkanmaa region, Finland, in 2014-2016. The participants consisted of 228 mother-child pairs (child age 5-7 years). The primary outcomes of interest were tri-axial accelerometer-derived SB and PA, which were measured in weeks one (baseline), two, and eight in both the intervention and control groups. Further, the mothers and children in the intervention group used a movement-to-music video program from the beginning of week two to the end of week eight. Secondary outcomes included self-reported screen time. The statistical methods employed comprised an intention-to-treat and linear mixed effects model design. No statistically significant differences between groups were found in primary or secondary outcomes. Among the children in the control group, light PA decreased significantly over time and screen time increased from 89 (standard deviation, SD 37) to 99 (SD 41) min/d. Among mothers and children in the intervention group, no statistical differences were found. In supplementary analysis, the children who stayed at home instead of attending daycare/preschool had on average 25 (95% confidence interval, CI 19-30) min/d more sedentary time and 11 (95% CI 8-14) min/d less moderate-to-vigorous PA than those who were at daycare/preschool. The higher body mass index of mothers was related with 5 (95% CI 2-7) min/d more sedentary time and 1 (95% CI 0-2) min/d less moderate-to-vigorous PA. The movement-to-music video program did not change

    The long-term forecasting of energy supply and demand is an extremely important topic of fundamental research in Taiwan due to Taiwan's lack of natural resources, dependence on energy imports, and the nation's pursuit of sustainable development. In this article, we provide an overview of energy supply and demand in Taiwan, and a summary of the historical evolution and current status of its energy policies, as background to a description of the preparation and application of a Long-range Energy Alternatives Planning System (LEAP) model of Taiwan's energy sector. The Taiwan LEAP model is used to compare future energy demand and supply patterns, as well as greenhouse gas emissions, for several alternative scenarios of energy policy and energy sector evolution. Results of scenarios featuring 'business-as-usual' policies, aggressive energy-efficiency improvement policies, and on-schedule retirement of Taiwan's three existing nuclear plants are provided and compared, along with sensitivity cases exploring the impacts of lower economic growth assumptions. A concluding section provides an interpretation of the implications of model results for future energy and climate policies in Taiwan. - Research highlights: → The LEAP model is useful for international energy policy comparison. → Nuclear power plants have significant, positive impacts on CO 2 emission. → The most effective energy policy is to adopt demand-side management. → Reasonable energy pricing provides incentives for energy efficiency and conservation. → Financial crisis has less impact on energy demand than aggressive energy policy.

    The majority of the current surgical simulators employ specialized sensory equipment for instrument tracking. The Leap Motion controller is a new device able to track linear objects with sub-millimeter accuracy. The aim of this study was to investigate the potential of a virtual reality (VR) simulator for assessment of basic laparoscopic skills, based on the low-cost Leap Motion controller. A simple interface was constructed to simulate the insertion point of the instruments into the abdominal cavity. The controller provided information about the position and orientation of the instruments. Custom tools were constructed to simulate the laparoscopic setup. Three basic VR tasks were developed: camera navigation (CN), instrument navigation (IN), and bimanual operation (BO). The experiments were carried out in two simulation centers: MPLSC (Athens, Greece) and CRESENT (Riyadh, Kingdom of Saudi Arabia). Two groups of surgeons (28 experts and 21 novices) participated in the study by performing the VR tasks. Skills assessment metrics included time, pathlength, and two task-specific errors. The face validity of the training scenarios was also investigated via a questionnaire completed by the participants. Expert surgeons significantly outperformed novices in all assessment metrics for IN and BO (p assessment of basic laparoscopic skills. The proposed system allowed the evaluation of dexterity of the hand movements. Future work will involve comparison studies with validated simulators and development of advanced training scenarios on current Leap Motion controller.

    Full Text Available Active listening is a communication skill which is crucial for the development of cooperative relationships in the group, culture of friendship and fellowship, it is also important for the development of literacy skills and talent for speaking. Furthermore, it contributes to the improvement of the level of knowledge, skills and school achievement, as well as to the development of self-confidence of children. Developing of active listening is an important task in the activities with children of preschool age. In this paper, the author, wanting to determine the importance of the factors of active listening of preschool children, examines how preschool teachers (N = 198: (a evaluate the importance of certain elements of active listening that relate to the speaker and the listener, and (b estimate their role in the process of developing active listening skills of preschool children as an essential element of successful interpersonal communication. Results of the survey show that preschool teachers attach greater importance to the factors of active listening related to the listener (attention, listening skill, interest in the subject, than to the factors related to the speaker (motivation for listening, quality of the narrative. More than two-thirds of surveyed preschool teachers (172 or 86.9% define its impact on the stimulation of active listening of children as significant. Work experience and professional qualifications as independent variables significantly influence the attitudes of preschool teachers about the importance of their impact in stimulating active listening. Preschool teacher is a key element of the training of preschool children in the area of the basic communication skills of active listening. In this sense, the results of our survey show that in the context of academic study programs for education of preschool teachers special attention is given to the communication skills and to their role in the development of active listening

    A bench-scale photobioreactor system, termed Laboratory Environmental Algae Pond Simulator (LEAPS), was designed and constructed to simulate outdoor pond cultivation for a wide range of geographical locations and seasons. The LEAPS consists of six well-mixed glass column photobioreactors sparged with CO2-enriched air to maintain a set-point pH, illuminated from above by a programmable multicolor LED lighting (0 to 2,500 µmol/m2-sec), and submerged in a temperature controlled water-bath (-2 °C to >60 °C). Measured incident light intensities and water temperatures deviated from the respective light and temperature set-points on average only 2.3% and 0.9%, demonstrating accurate simulation of light and temperature conditions measured in outdoor ponds. In order to determine whether microalgae strains cultured in the LEAPS exhibit the same linear phase biomass productivity as in outdoor ponds, Chlorella sorokiniana and Nannochloropsis salina were cultured in the LEAPS bioreactors using light and temperature scripts measured previously in the respective outdoor pond studies. For Chlorella sorokiniana, the summer season biomass productivity in the LEAPS was 6.6% and 11.3% lower than in the respective outdoor ponds in Rimrock, Arizona, and Delhi, California; however, these differences were not statistically significant. For Nannochloropsis salina, the winter season biomass productivity in the LEAPS was statistically significantly higher (15.2%) during the 27 day experimental period than in the respective outdoor ponds in Tucson, Arizona. However, when considering only the first 14 days, the LEAPS biomass productivity was only 9.2% higher than in the outdoor ponds, a difference shown to be not statistically significant. Potential reasons for the positive or negative divergence in LEAPS performance, relative to outdoor ponds, are discussed. To demonstrate the utility of the LEAPS in predicting productivity, two other strains – Scenedesmus obliquus and Stichococcus minor

    The burden of the childhood obesity epidemic is well recognized; nevertheless, the genetic markers and gene-environment interactions associated with the development of common obesity are still unknown. In this study, candidate genes associated to satiety and appetite control pathways with obesity-related traits were tested in Caucasian preschoolers from the STRONG Kids project. Eight genetic variants in genes related to obesity (BDNF, LEPR, FTO, PCSK1, POMC, TUB, LEP, and MC4R) were genotyped in 128 children from the STRONG Kids project (mean age 39.7 months). Data were analyzed for individual associations and to test for genetic predisposition scores (GPSs) with body mass index (BMI) and anthropometric traits (Z-scores, e.g. height-for-age Z-score, HAZ). Covariates included age, sex, and breastfeeding (BF) duration. Obesity and overweight prevalence was 6.3 and 19.5%, respectively, according to age- and sex-specific BMI percentiles. Individual genetic associations of MC4R and LEPR markers with HAZ were strengthened when BF duration was included as a covariate. Our GPSs show that, as the number of risk alleles increased, the risk of higher BMI and HAZ also increased. Overall, the GPSs assembled were able to explain 2-3% of the variability in BMI and HAZ phenotypes. Genetic associations with common obesity-related phenotypes were found in the STRONG Kids project. GPSs assembled for specific candidate genes were associated with BMI and HAZ phenotypes. © 2013 S. Karger AG, Basel.

    In recent years host antimicrobial peptides and proteins have been recognised as key mediators of the innate immune response in many vertebrate species, providing the first line of defense against potential pathogens. In chickens a number of cationic antimicrobial peptides have been recently identified. However, although these peptides have been studied extensively in the avian gastrointestinal tract, little is known about their function in the chicken reproductive organs and embryos. Chicken Liver Expressed Antimicrobial Peptide-2 (cLEAP-2) has been previously reported to function in protecting birds against microbial attack. The aim of this study was to investigate the expression of cLEAP-2 gene in the chicken reproductive organs, as well as in chicken embryos during embryonic development, and to determine whether cLEAP-2 expression in the chicken reproductive organs was constitutive or induced as a response to Salmonella enteritidis infection. RNA was extracted from ovary, oviduct, testis and epididymis of sexually mature healthy and Salmonella infected birds, as well as from chicken embryos until day ten of embryonic development. Expression analysis data revealed that cLEAP-2 was expressed in the chicken ovary, testis and epididymis as well as in embryos during early embryonic development. Quantitative real-time PCR analysis revealed that cLEAP-2 expression was constitutive in the chicken epididymis, but was significantly up regulated in the chicken gonads, following Salmonella infection. In addition, expression of cLEAP-2 during chicken embryogenesis appeared to be developmentally regulated. These data provide evidence to suggest a key role of cLEAP-2 in the protection of the chicken reproductive organs and the developing embryos from Salmonella colonization.

    Full Text Available The purpose of this study was to discover the transformation preschool teacher candidates go through in their perceptions about teacher and teaching during their teacher education program. The participants of the study were 35 senior students enrolled in the preschool teacher education program at a university located in the Eastern Anatolian Region of Turkey. A qualitative survey instrument was conducted to examine the preservice teachers’ perceptions. The data collected from the survey were analyzed by adopting a constant comparative coding method. The study revealed a change in the participants’ perceptions about preschool education before and after they enrolled in the program. The hardest parts of teaching in preschool were the need of high level of energy, patience, and skills to manage the classroom while the most pleasurable sides were having fun, play opportunities, and the positive impact teachers make on children. The qualities of an ideal preschool program listed by the participants involved curriculum, physical environment, and social-emotional atmosphere while the themes regarding the ideal preschool teacher were revolved around the personal qualities, professional attitude, and professional knowledge and skills. Hence, the findings of this qualitative study can only be generalized in the context the study was conducted; however, the study could have important implications for preschool teacher education in Turkey and in other countries, and help the international readers perceive preschool teacher education from a different perspective.

    Although motion analysis is frequently employed in upper limb motor assessment (e.g. visually-guided reaching), they are resource-intensive and limited to laboratory settings. This study evaluated the reliability and accuracy of a new markerless motion capture device, the Leap Motion controller, to measure finger position. Testing conditions that influence reliability and agreement between the Leap and a research-grade motion capture system were examined. Nine healthy young adults pointed to 15 targets on a computer screen under two conditions: (1) touching the target (touch) and (2) 4 cm away from the target (no-touch). Leap data was compared to an Optotrak marker attached to the index finger. Across all trials, root mean square (RMS) error of the Leap system was 17.30  ±  9.56 mm (mean ± SD), sampled at 65.47  ±  21.53 Hz.

    Full Text Available The transient radiative transfer in 1-D homogeneous media with ultra-short Gaussian pulse laser irradiated was investigation by the finite volume method. The concept of optimal detection distance was proposed. The radiation characteristic was studied thoroughly. Afterwards, a memetic meta-heuristic shuffled frog leaping algorithm was introduced to inverse transient radiative problems. It is demonstrated that the extinction coefficient and scattering albedo can be retrieved accurately even with noisy data in a homogeneous absorbing and isotropic scattering plane-parallel slab. Finally, a technique was proposed to accelerate the inverse process by reducing the searching space of the radiative parameters.

    2018-01-01

    Full Text Available Motions using Leap Motion controller are not standardized while the use of it is spreading in media contents. Each content defines its own motions, thereby creating confusion for users. Therefore, to alleviate user inconvenience, this study categorized the commonly used motion by Amusement and Functional Contents and defined the Structural Motion Grammar that can be universally used based on the classification. To this end, the Motion Lexicon was defined, which is a fundamental motion vocabulary, and an algorithm that enables real-time recognition of Structural Motion Grammar was developed. Moreover, the proposed method was verified by user evaluation and quantitative comparison tests.

    Cobb, J.W.; Leboeuf, J.N.

    1994-01-01

    The authors present a particle algorithm to extend simulation capabilities for plasma based materials processing reactors. The orbit integrator uses a syncopated leap-frog algorithm in cylindrical coordinates, which maintains second order accuracy, and minimizes computational complexity. Plasma source terms are accumulated orbit consistently directly in the frequency and azimuthal mode domains. Finally they discuss the numerical analysis of this algorithm. Orbit consistency greatly reduces the computational cost for a given level of precision. The computational cost is independent of the degree of time scale separation

    Christakis, Dimitri A; Garrison, Michelle M

    2009-12-01

    The goal was to quantify television viewing in day care settings and to investigate the characteristics of programs that predict viewing. A telephone survey of licensed child care programs in Michigan, Washington, Florida, and Massachusetts was performed. The frequency and quantity of television viewing for infants, toddlers, and preschool-aged children were assessed. With the exception of infants, children in home-based child care programs were exposed to significantly more television on an average day than were children in center-based programs (infants: 0.2 vs 0 hours; toddlers: 1.6 vs 0.1 hours; preschool-aged children: 2.4 vs 0.4 hours). In a regression analysis of daily television time for preschool-aged children in child care, center-based programs were found to have an average of 1.84 fewer hours of television each day, controlling for the other covariates. Significant effect modification was found, in that the impact of home-based versus center-based child care programs differed somewhat depending on educational levels for staff members; having a 2- or 4-year college degree was associated with 1.41 fewer hours of television per day in home-based programs, but no impact of staff education on television use was observed in center-based programs. For many children, previous estimates of screen time significantly underestimated actual amounts. Pediatricians should council parents to minimize screen time in child care settings.

  17. Shuffled Frog Leaping Algorithm for Preemptive Project Scheduling Problems with Resource Vacations Based on Patterson Set

    Directory of Open Access Journals (Sweden)

    Yi Han

    2013-01-01

    Full Text Available This paper presents a shuffled frog leaping algorithm (SFLA for the single-mode resource-constrained project scheduling problem where activities can be divided into equant units and interrupted during processing. Each activity consumes 0–3 types of resources which are renewable and temporarily not available due to resource vacations in each period. The presence of scarce resources and precedence relations between activities makes project scheduling a difficult and important task in project management. A recent popular metaheuristic shuffled frog leaping algorithm, which is enlightened by the predatory habit of frog group in a small pond, is adopted to investigate the project makespan improvement on Patterson benchmark sets which is composed of different small and medium size projects. Computational results demonstrate the effectiveness and efficiency of SFLA in reducing project makespan and minimizing activity splitting number within an average CPU runtime, 0.521 second. This paper exposes all the scheduling sequences for each project and shows that of the 23 best known solutions have been improved.

  18. Does LEAP change the screening paradigm for food allergy in infants with eczema?

    Science.gov (United States)

    Allen, K J; Koplin, J J

    2016-01-01

    The LEAP randomized controlled trial provides the first direct evidence that delayed introduction of peanut in an infant's diet significantly increases the risk of peanut allergy. However, as often is the case in ground-breaking research, the LEAP study raises almost as many questions as it resolves. Although the quality of design and excellence in study execution is unquestioned, the particular difficulty this study raises is how to generalize results from a trial of high-risk infants, which screened infants for the presence of peanut allergy prior to peanut introduction, to the general population. Although many existing infant feeding guidelines already allow for the introduction of allergenic foods from 4 to 6 months of age irrespective of co-existent risk factors for peanut allergy, these will now need to be revised to more strongly state that avoidance may be harmful. Interim guidelines have already been published which incorporate these recommendations. However, the question as to how to achieve timely introduction of peanut into an infant's diet in a safe and cost-effective way, particularly in high-risk infants, remains unresolved. © 2015 John Wiley & Sons Ltd.

    2010-05-15

    A research associated with urban transportation was carried out in Rawalpindi and Islamabad to analyze the status of emission of air pollutants and energy demands. The study included a discussion of past trends and future scenarios in order to reduce the future emissions. A simple model of passenger transport has been developed using computer based software called Long-Range Energy Alternatives Planning System (LEAP). The LEAP model was used to estimate total energy demand and the vehicular emissions for the base year 2000 and extrapolated till 2030 for the future predictions. Transport database in Rawalpindi and Islamabad, together with fuel consumption values for the vehicle types and emission factors of NO{sub x}, SO{sub 2} and PM{sub 10} corresponding to the actual vehicle types, formed the basis of the transport demand, energy consumption and total emission calculations. Apart from base scenario, the model was run under three alternative scenarios to study the impact of different urban transport policy initiatives that would reduce energy demand and emissions in transport sector of Rawalpindi and Islamabad. The prime objective was to arrive at an optimal transport policy, which limits the future growth of fuel consumption as well as air pollution. (author)

  20. The Characters of Leap Years in Qing Calendars (1644-1911)

    Science.gov (United States)

    Lu, Dalong

    In Qing Dynasty (1644-1911) three different calendars had been put into use which titles are Xiyang Xinfa Lishu (Treatise on Astronomy and Calendrical Science according to the New Method in West 1645-1666) Yuzhi Lixiang Kaocheng (Compendium of Calendrical Science and Astronomy compiled by Imperial Order 1725-1742) and Yuzhi Lixiang Kaocheng Houbian (Sequel Compendium of Calendrical Science and Astronomy compiled by Imperial Order 1742-1911). The characters of leap years in the three calendars are different for the last one which is selected the year of 1723 as it epoch and named as Guimao Yuan Li. This calendar is based on the 33-year pattern of leap years (there is a rather exact accord between days and years over this interval with eight days being intercalated per 33 years) and is slightly different from the former two calendars. Therefore the calendars of Qing Dynasty complied by Western Jesuits and Chinese astronomers can be regarded as the remarkable achievements in the history of calendar in the world.

  1. Flying fish accelerate at 5 G to leap from the water surface

    Science.gov (United States)

    Yang, Patricia; Phonekeo, Sulisay; Xu, Ke; Chang, Shui-Kai; Hu, David

    2013-11-01

    Flying fish can both swim underwater and glide in air. Transitioning from swimming to gliding requires penetration of the air-water interface, or breaking the ``surface tension barrier,'' a formidable task for juvenile flying fish measuring 1 to 5 cm in length. In this experimental investigation, we use high-speed videography to characterize the kinematics of juvenile flying fish as they leap from the water surface. During this process, which lasts 0.05 seconds, flying fish achieve body accelerations of 5 times earth's gravity and gliding speeds of 1.3 m/s, an order of magnitude higher than their steady swimming speed. We rationalize this anomalously high speed on the basis of the hydrodynamic and surface tension forces and torques experienced by the fish. Specifically, leaping fish experience skin friction forces only on the submerged part of their body, permitting them to achieve much higher speeds than in steady underwater swimming. We also perform experiments using a towed flying fish mimc to determine optimality of various parameters in this process, including body angle and start position with respect to the water surface.

  2. An improved shuffled frog leaping algorithm based evolutionary framework for currency exchange rate prediction

    Science.gov (United States)

    Dash, Rajashree

    2017-11-01

    Forecasting purchasing power of one currency with respect to another currency is always an interesting topic in the field of financial time series prediction. Despite the existence of several traditional and computational models for currency exchange rate forecasting, there is always a need for developing simpler and more efficient model, which will produce better prediction capability. In this paper, an evolutionary framework is proposed by using an improved shuffled frog leaping (ISFL) algorithm with a computationally efficient functional link artificial neural network (CEFLANN) for prediction of currency exchange rate. The model is validated by observing the monthly prediction measures obtained for three currency exchange data sets such as USD/CAD, USD/CHF, and USD/JPY accumulated within same period of time. The model performance is also compared with two other evolutionary learning techniques such as Shuffled frog leaping algorithm and Particle Swarm optimization algorithm. Practical analysis of results suggest that, the proposed model developed using the ISFL algorithm with CEFLANN network is a promising predictor model for currency exchange rate prediction compared to other models included in the study.

  4. Promoting Social and Emotional Competencies among Young Children in Croatia with Preschool PATHS.

    Directory of Open Access Journals (Sweden)

    Josipa Mihic

    2016-11-01

    Full Text Available Preschool PATHS (Promoting Alternative Thinking Strategies is an evidence-based universal prevention program focused on promoting children’s social and emotional competencies and reducing the likelihood of behaviour problems and negative relationships with peers and teachers. This paper examines changes in the social and emotional competencies of the first children to participate in Preschool PATHS in Croatia. This study included 164 children, ages 3-6, in 12 preschool classrooms in three cities across Croatia, who participated in the classroom-based Preschool PATHS curriculum. At the beginning and end of the preschool year, teachers completed wellvalidated and reliable assessments of social and emotional competencies on each child. Hierarchical linear models revealed statistically significant and substantial improvements in prosocial behaviour, emotion regulation, emotion symptoms, peer problems, relational aggression, conduct problems, and hyperactive-impulsive behaviour. Study findings reveal significant changes in children’s social and emotional competencies during preschool. This time may present a unique opportunity to buttress children’s skills and improve long-term school success through the implementation of a rigorous empiricallyvalidated prevention program such as Preschool PATHS.

    2017-07-01

    The goal of this paper is to review the research literature regarding the needs of preschoolers in the context of disasters and terrorism with the aim of understanding the existing methods for assessment, prevention, and intervention to provide recommendations and point out required research and development. We differentiate between screening tools that provide initial evaluation and assessment tools for diagnosing preschooler children's pathology and review possible interventions that address the preschool child's needs before, during, and after the incident itself. We also emphasize the lack of dissemination and research of prevention programs and mass interventions for preschoolers. Programs for community mass prevention and intervention for preschoolers should be developed and evaluated and interventions should be adapted for individual and group delivery. Moreover, the increase in the number of children refugees requires cultural adaptations of assessment measures and interventions.

    Expression of peptide transporter 1 (PepT1) and liver-expressed antimicrobial peptide 2 (LEAP-2) in chickens can be influenced by food deprivation, pathological conditions and drug administration. Effect of three putative probiotic Lactobacillus strains and enrofloxacin on the expression of PepT1 and LEAP-2 mRNA was investigated in Ross 308 chickens. One-day-old chicks (n = 24) were allocated to following groups: control (without treatment); group treated with probiotics via feed; group treated with a combination of probiotics and enrofloxacin; and a group given enrofloxacin only. The drug was administered at a dose of 10 mg kg -1 , via drinking water for 5 days. Samples from liver, duodenum and jejunum were collected 126 h after the start of the treatment. Expression levels of PepT1 and LEAP-2 were determined by real-time polymerase chain reaction and were statistically evaluated by Mann-Whitney test. Enrofloxacin administered alone or in combination with probiotics provoked a statistically significant up-regulation of PepT1 mRNA levels in the measured organ sites. These changes can be attributed to a tendency of improvement in utilization of dietary peptide and in body weight gain. LEAP-2 mRNA expression levels did not change significantly in enrofloxacin-treated chickens in comparison with control group.

    2013-01-03

    This study aimed to compare the levels of objectively-measured sedentary behavior in children attending Montessori preschools with those attending traditional preschools. The participants in this study were preschool children aged 4 years old who were enrolled in Montessori and traditional preschools. The preschool children wore ActiGraph accelerometers. Accelerometers were initialized using 15-second intervals and sedentary behavior was defined as Montessori preschools, after adjusting for selected potential correlates of preschoolers' sedentary behavior. Children attending Montessori preschools spent less time in sedentary behavior than those attending traditional preschools during the in-school (44.4. min/hr vs. 47.1 min/hr, P = 0.03), after-school (42.8. min/hr vs. 44.7 min/hr, P = 0.04), and total-day (43.7 min/hr vs. 45.5 min/hr, P = 0. 009) periods. School type (Montessori or traditional), preschool setting (private or public), socio-demographic factors (age, gender, and socioeconomic status) were found to be significant predictors of preschoolers' sedentary behavior. Levels of objectively-measured sedentary behavior were significantly lower among children attending Montessori preschools compared to children attending traditional preschools. Future research should examine the specific characteristics of Montessori preschools that predict the lower levels of sedentary behavior among children attending these preschools compared to children attending traditional preschools.

  15. LEAP [Low-Energy Antiproton]: A balloon-borne search for low-energy cosmic-ray antiprotons

    Moats, A.R.M.

    1989-01-01

    The LEAP (Low-Energy Antiproton) experiment is a search for cosmic-ray antiprotons in the 120 MeV to 1.2 GeV kinetic energy range. The motivation for this project was the result announced by Buffington et. al. (1981) that indicated an anomalously high antiproton flux below 300 MeV; this result has compelled theorists to propose sources of primary antiprotons above the small secondary antiproton flux produced by high energy cosmic-ray collisions with nuclei in the interstellar medium. LEAP consisted of the NMSU magnetic spectrometer, a time-of-flight system designed at Goddard Space Flight Center, two scintillation detectors, and a Cherenkov counter designed and built at the University of Arizona. Analysis of flight data performed by the high-energy astrophysics group at Goddard Space Flight Center revealed no antiproton candidates found in the 120 MeV to 360 MeV range; 3 possible antiproton candidate events were found in the 500 MeV to 1.2 GeV range in an analysis done here at the University of Arizona. However, since it will be necessary to sharpen the calibration on all of the LEAP systems in order to positively identify these events as antiprotons, only an upper limit has been determined at present. Thus, combining the analyses performed at the University of Arizona and Goddard Space Flight Center, 90% confidence upper limits of 3.5 x 10 -5 in the 120 MeV to 360 MeV range and 2.3 x 10 -4 in the 500 MeV to 1.2 GeV range for the antiproton/proton ratio is indicated by the LEAP results. LEAP disagrees sharply with the results of the Buffington group, indicating a low antiproton flux at these energies

  16. Optimal inverse magnetorheological damper modeling using shuffled frog-leaping algorithm–based adaptive neuro-fuzzy inference system approach

    2016-08-01

    Full Text Available Magnetorheological dampers have become prominent semi-active control devices for vibration mitigation of structures which are subjected to severe loads. However, the damping force cannot be controlled directly due to the inherent nonlinear characteristics of the magnetorheological dampers. Therefore, for fully exploiting the capabilities of the magnetorheological dampers, one of the challenging aspects is to develop an accurate inverse model which can appropriately predict the input voltage to control the damping force. In this article, a hybrid modeling strategy combining shuffled frog-leaping algorithm and adaptive-network-based fuzzy inference system is proposed to model the inverse dynamic characteristics of the magnetorheological dampers for improving the modeling accuracy. The shuffled frog-leaping algorithm is employed to optimize the premise parameters of the adaptive-network-based fuzzy inference system while the consequent parameters are tuned by a least square estimation method, here known as shuffled frog-leaping algorithm-based adaptive-network-based fuzzy inference system approach. To evaluate the effectiveness of the proposed approach, the inverse modeling results based on the shuffled frog-leaping algorithm-based adaptive-network-based fuzzy inference system approach are compared with those based on the adaptive-network-based fuzzy inference system and genetic algorithm–based adaptive-network-based fuzzy inference system approaches. Analysis of variance test is carried out to statistically compare the performance of the proposed methods and the results demonstrate that the shuffled frog-leaping algorithm-based adaptive-network-based fuzzy inference system strategy outperforms the other two methods in terms of modeling (training accuracy and checking accuracy.

  20. Science in the Eyes of Preschool Children: Findings from an Innovative Research Tool

    Science.gov (United States)

    Dubosarsky, Mia D.

    How do young children view science? Do these views reflect cultural stereotypes? When do these views develop? These fundamental questions in the field of science education have rarely been studied with the population of preschool children. One main reason is the lack of an appropriate research instrument that addresses preschool children's developmental competencies. Extensive body of research has pointed at the significance of early childhood experiences in developing positive attitudes and interests toward learning in general and the learning of science in particular. Theoretical and empirical research suggests that stereotypical views of science may be replaced by authentic views following inquiry science experience. However, no preschool science intervention program could be designed without a reliable instrument that provides baseline information about preschool children's current views of science. The current study presents preschool children's views of science as gathered from a pioneering research tool. This tool, in the form of a computer "game," does not require reading, writing, or expressive language skills and is operated by the children. The program engages children in several simple tasks involving picture recognition and yes/no answers in order to reveal their views about science. The study was conducted with 120 preschool children in two phases and found that by the age of 4 years, participants possess an emergent concept of science. Gender and school differences were detected. Findings from this interdisciplinary study will contribute to the fields of early childhood, science education, learning technologies, program evaluation, and early childhood curriculum development.

  1. Noosphere: Does the Internet Provide an Evolutionary Leap to a Higher Level of Collective Intelligence?

    Directory of Open Access Journals (Sweden)

    Tatjana Milivojević

    2015-09-01

    Full Text Available The neologism noosphere signifies global human consciousness. According to T. de Chardin, it is the third stage in the development of the earth, after the geosphere and the biosphere. As well as the emergence of life has fundamentally changed the geosphere, the emergence of human consciousness has fundamentally changed the biosphere. De Chardin envisioned the “planetarization” of mankind, which is equivalent to the current globalization by information technology. From an anthropological point of view, internet is not a technology or media as others: it has the potential to revolutionize the current civilizational paradigm. With the advent of the internet the idea of the noosphere has been reactualized and related to the concept of collective intelligence. The article questions the hypothesis of an evolutionary leap in a greater collective intelligence or higher level of collective consciousness presenting pros and cons.

    2008-01-01

    In 2004, the total energy consumption in Thailand increased 8.8 per cent, from 47,806 to 60,260 ktoe. Long-range Energy Alternatives Planning (LEAP) is an accounting tool that simulates future energy scenarios. According to a Business As Usual (BAU) case, the overall energy demand in Thailand is estimated to increase from 61,262 to 254,200 ktoe between 2004 and 2030. Commercial energy consumption, which comprises petroleum products, natural gas, coal and its products, and electricity, increased by 9.0 per cent in Thailand in 2004, and new and renewable energy increased by 7.8 per cent. Nearly 60 per cent of the total commercial energy supply in Thailand was imported and increased for a fifth year in a row. The changes in energy consumption can be attributed to population growth and increase in economic activity and development. 10 refs., 5 tabs., 14 figs

  3. Medium- and Long-term Prediction of LOD Change by the Leap-step Autoregressive Model

    2015-08-01

    The accuracy of medium- and long-term prediction of length of day (LOD) change base on combined least-square and autoregressive (LS+AR) deteriorates gradually. Leap-step autoregressive (LSAR) model can significantly reduce the edge effect of the observation sequence. Especially, LSAR model greatly improves the resolution of signals’ low-frequency components. Therefore, it can improve the efficiency of prediction. In this work, LSAR is used to forecast the LOD change. The LOD series from EOP 08 C04 provided by IERS is modeled by both the LSAR and AR models. The results of the two models are analyzed and compared. When the prediction length is between 10-30 days, the accuracy improvement is less than 10%. When the prediction length amounts to above 30 day, the accuracy improved obviously, with the maximum being around 19%. The results show that the LSAR model has higher prediction accuracy and stability in medium- and long-term prediction.

    It is known that the accuracies of medium- and long-term prediction of changes of length of day (LOD) based on the combined least-square and autoregressive (LS+AR) decrease gradually. The leap-step autoregressive (LSAR) model is more accurate and stable in medium- and long-term prediction, therefore it is used to forecast the LOD changes in this work. Then the LOD series from EOP 08 C04 provided by IERS (International Earth Rotation and Reference Systems Service) is used to compare the effectiveness of the LSAR and traditional AR methods. The predicted series resulted from the two models show that the prediction accuracy with the LSAR model is better than that from AR model in medium- and long-term prediction.

    This article analyzes a neat conjuring trick employed in bioethics, that is, the immediate conversion of a philosophical conclusion into a policy prescription, and compares it to the "grand leap of the whale up the Niagara Falls" mentioned by Benjamin Franklin. It is shown that there is no simple and easy way to achieve the conversion, by considering arguments falling under four headings: (1) reasonable disagreement about values and theories, (2) general jurisprudential arguments, (3) the differences between policymaking and philosophy, and (4) the messy world of implementation. The particular issue used to illustrate the difficulties in moving from philosophical conclusion to policy description is infanticide of healthy infants, but the analysis is general, and the conclusion that the immediate move to policy is illegitimate is quite general.

     In evolutionary linguistics, experiments using artificial signal spaces are being used to investigate the emergenceof speech structure. These signal spaces need to be continuous, non-discretized spaces from which discrete unitsand patterns can emerge. They need to be dissimilar from-but comparable with-the vocal tract, in order tominimize interference from pre-existing linguistic knowledge, while informing us about language. This is a hardbalance to strike. This article outlines a new approach that uses the Leap Motion, an infrared controller that canconvert manual movement in 3d space into sound. The signal space using this approach is more flexible than signalspaces in previous attempts. Further, output data using this approach is simpler to arrange and analyze. Theexperimental interface was built using free, and mostly open- source libraries in Python. We provide our sourcecode for other researchers as open source.

    The main goal of this study is to investigate the potential of the Leap Motion Controller (LMC) for the objective assessment of motor dysfunctioning in patients with Parkinson's disease (PwPD). The most relevant clinical signs in Parkinson's Disease (PD), such as slowness of movements, frequency variation, amplitude variation, and speed, were extracted from the recorded LMC data. Data were clinically quantified using the LMC software development kit (SDK). In this study, 16 PwPD subjects and 12 control healthy subjects were involved. A neurologist assessed the subjects during the task execution, assigning them a score according to the MDS/UPDRS-Section III items. Features of motor performance from both subject groups (patients and healthy controls) were extracted with dedicated algorithms. Furthermore, to find out the significance of such features from the clinical point of view, machine learning based methods were used. Overall, our findings showed the moderate potential of LMC to extract the motor performance of PwPD.

    As a measure to establish a climate-friendly energy system, Korean government has proposed to expand landfill gas (LFG) electricity generation capacity. The purpose of this paper is to analyze the impacts of LFG electricity generation on the energy market, the cost of generating electricity and greenhouse gases emissions in Korea using a computer-based software tool called 'Long-range Energy Alternative Planning system' (LEAP) and the associated 'Technology and Environmental Database'. In order to compare LFG electricity generation with existing other generating facilities, business as usual scenario of existing power plants was surveyed, and then alternative scenario investigations were performed using LEAP model. Different alternative scenarios were considered, namely the base case with existing electricity facilities, technological improvement of gas engine and LFG maximum utilization potential with different options of gas engine (GE), gas turbine (GT), and steam turbine (ST). In the technological improvement scenario, there will be 2.86 GWh or more increase in electricity output, decrease of 45 million won (Exchange rate (1$=1200 won)). in costs, and increase of 10.3 thousand ton of CO 2 in global warming potentials due to same period (5 year) of technological improvement. In the maximum utilization potential scenario, LFG electricity generation technology is substituted for coal steam, nuclear, and combined cycle process. Annual cost per electricity product of LFG electricity facilities (GE 58MW, GT 53.5MW, and ST 54.5MW) are 45.1, 34.3, and 24.4 won/kWh, and steam turbine process is cost-saving. LFG-utilization with other forms of energy utilization reduces global warming potential by maximum 75% with compared to spontaneous emission of CH 4 . LFG electricity generation would be the good solution for CO 2 displacement over the medium term and additional energy profits

    Full Text Available Hand rehabilitation is fundamental after stroke or surgery. Traditional rehabilitation requires a therapist and implies high costs, stress for the patient, and subjective evaluation of the therapy effectiveness. Alternative approaches, based on mechanical and tracking-based gloves, can be really effective when used in virtual reality (VR environments. Mechanical devices are often expensive, cumbersome, patient specific and hand specific, while tracking-based devices are not affected by these limitations but, especially if based on a single tracking sensor, could suffer from occlusions. In this paper, the implementation of a multi-sensors approach, the Virtual Glove (VG, based on the simultaneous use of two orthogonal LEAP motion controllers, is described. The VG is calibrated and static positioning measurements are compared with those collected with an accurate spatial positioning system. The positioning error is lower than 6 mm in a cylindrical region of interest of radius 10 cm and height 21 cm. Real-time hand tracking measurements are also performed, analysed and reported. Hand tracking measurements show that VG operated in real-time (60 fps, reduced occlusions, and managed two LEAP sensors correctly, without any temporal and spatial discontinuity when skipping from one sensor to the other. A video demonstrating the good performance of VG is also collected and presented in the Supplementary Materials. Results are promising but further work must be done to allow the calculation of the forces exerted by each finger when constrained by mechanical tools (e.g., peg-boards and for reducing occlusions when grasping these tools. Although the VG is proposed for rehabilitation purposes, it could also be used for tele-operation of tools and robots, and for other VR applications.

    Highlights: • Electro-thermal performance of open-loop controlled dual axis CPVT is investigated. • For using the absorbed heat, active ventilation with a heat storage tank is used. • Economic optimization of the system is performed, using Frog Leap algorithm. • Detailed model of all sections is simulated with their characteristics evaluation. • Triple-junction photovoltaic cells, which are the most recent technology, are used. - Abstract: In this study, design and optimization of a concentrated photovoltaic thermal (CPVT) system considering electrical, mechanical, and economical aspects is investigated. For this purpose, each section of the system is simulated in MATLAB, in detail. Triple-junction photovoltaic cells, which are the most recent technology, are used in this study. They are more efficient in comparison to conventional photovoltaic cells. Unlike ordinary procedures, in this work active ventilation is used for absorbing the thermal power of radiation, using heat storage tanks, which not only results in increasing the electrical efficiency of the system through decreasing the temperature, but also leads to storing and managing produced thermal energy and increasing the total efficiency of the system up to 85 percent. The operation of the CPVT system is investigated for total hours of the year, considering the needed thermal load, meteorological conditions, and hourly radiation of Khuznin, a city in Qazvin province, Iran. Finally, the collector used for this system is optimized economically, using frog leap algorithm, which resulted in the cost of 13.4 $/m"2 for a collector with the optimal distance between tubes of 6.34 cm.

    The primary purpose of this study was to examine feasibility of the preschool version of the First Step to Success (FSS) intervention. Toward this end, the following four research questions were addressed: (1) To what extent was the intervention implemented with integrity? (2) To what extent do teachers and parents perceive the intervention to be socially valid? (3) To what extent were teachers and parents satisfied with the intervention? and (4) To what extent was the intervention effective in reducing problem behavior and improving social skills? Twelve students participated in the study. Treatment integrity, social validity, and satisfaction results were analyzed at the aggregate level, and a reliable change index was calculated at the case level for primary outcome measures to assess the potential efficacy of the intervention. Fidelity data suggest the preschool version of the intervention can be implemented with acceptable integrity by coaches and teachers in preschool settings. Social validity outcomes suggest parents' perceptions of the program's goals, procedures, and outcomes were extremely favorable, and social validity from the teacher perspective was acceptable. The results provide initial evidence that participating in the preschool version of the FSS intervention improves children's social skills and decreases problem behavior.

    Full Text Available Objective: To investigate expressiveness of motor impairment in autism spectrum disorder (ASD and its correlation with developmental and clinical features of ASD. Method: Thirty-five male preschoolers with ASD completed the Peabody Developmental Motor Scales-2 (PDMS-2; Folio and Fewell, 2000 and underwent a multidisciplinary assessment including medical examination, standardized assessment of cognitive abilities, administration of Autism_Diagnostic_Observation_Schedule (ADOS and a parent interview about adaptive skills. Results: Results revealed a substantial impairment in locomotion and grasping skills. Both fine and gross motor skills were significantly correlated with non verbal IQ and adaptive behaviours (p<0.01 but not with chronological age or ADOS scores. Children with weaker motor skills have greater cognitive and adaptive behaviours deficits. Conclusions: Motor development in ASD can be detected at preschool age and locomotion and grasping skills are substantially the most impaired area. These findings support the need to assess motor skills in preschoolers with ASD in addition to other developmental skill areas. Along with the increasingly acknowledged importance of motor skills for subsequent social, cognitive, and communicative development our findings support the need to consider motor intervention as a key area in therapeutic program to improve outcome in preschoolers with ASD.

    2017-10-01

    To test how early social environments affect children's consideration of gender, 3- to 6-year-old children (N=80) enrolled in gender-neutral or typical preschool programs in the central district of a large Swedish city completed measures designed to assess their gender-based social preferences, stereotypes, and automatic encoding. Compared with children in typical preschools, a greater proportion of children in the gender-neutral school were interested in playing with unfamiliar other-gender children. In addition, children attending the gender-neutral preschool scored lower on a gender stereotyping measure than children attending typical preschools. Children at the gender-neutral school, however, were not less likely to automatically encode others' gender. The findings suggest that gender-neutral pedagogy has moderate effects on how children think and feel about people of different genders but might not affect children's tendency to spontaneously notice gender.

    The present review was undertaken in order to summarize and evaluate recent research investigating taste exposure, sensory learning, and nutrition education interventions for promoting vegetable intake in preschool children. Overall, taste exposure interventions yielded the best outcomes for increasing vegetable intake in early childhood. Evidence from sensory learning strategies such as visual exposure and experiential learning also show some success. While nutrition education remains the most common approach used in preschool settings, additional elements are needed to strengthen the educational program for increasing vegetable intake. There is a substantial gap in the evidence base to promote vegetable intake in food fussy children. The present review reveals the relative importance of different intervention strategies for promoting vegetable intake. To strengthen intervention effects for improving vegetable intake in preschool children, future research could consider integrating taste exposure and sensory learning strategies with nutrition education within the preschool curriculum.

    The purpose of this study was to identify the perception of childhood obesity in mothers of preschool children using Q methodology. A total of 38 Q statements about childhood obesity were obtained from 41 participants. The QUANL PC program was used to analyze the results. There were three types of perception toward obesity in mothers of preschool children: the "authoritative discipline type," the "generous home meal focused type," and the "home meal based on household financial situation type." The perception of mothers toward childhood obesity can affect the extent of maternal interaction with children or meal preparation for the family. Based on these results, it is necessary to plan specific programs according to the types of maternal perception toward childhood obesity.

    The current experiment sought to demonstrate the presence of wishful thinking--when wishes influence beliefs--in young children. A sample of 77 preschoolers needed to predict, eight times in a row, which of two plastic eggs, one containing one toy and the other containing three toys, would be drawn by a blinded experimenter. On the four trials in which the children could not keep the content of the egg drawn, they were equally likely to predict that either egg would be drawn. By contrast, on the four trials in which the children got to keep the content of the egg, they were more likely to predict that the egg with three toys would be drawn. Any effort the children exerted would be the same across conditions, so that this demonstration of wishful thinking cannot be accounted for by an effort heuristic. One group of children--a subgroup of the 5-year-olds--did not engage in wishful thinking. Children from this subgroup instead used the representativeness heuristic to guide their answers. This result suggests that having an explicit representation of the outcome inhibits children from engaging in wishful thinking in the same way as explicit representations constrain the operation of motivated reasoning in adults.

  1. Gendering in one Icelandic preschool

    Directory of Open Access Journals (Sweden)

    2014-05-01

    Full Text Available The aim of this article is to shed light on gendering in preschool. It analyzes the opinions and beliefs of preschool teachers with regard to boys and girls in one Icelandic preschool, and how gender performative acts are manifested in the preschool’s children. The preschool, which was observed for one school year, comprised 60 children, aged 18 months to five years, and 20 employees, of which eight were qualified teachers. The research material is analyzed in terms of Judith Butler’s gender constructivism. Butler contends that gender is constituted by, and is a product of, society, and that the individual’s empowerment is therefore limited in relation to society, with individuals typically seeking to identify themselves with the dominant norms concerning gender. The main conclusions suggest that “gendering” is prominent within the preschool. There is a strong tendency among the preschool teachers to classify the children into categories of boys/masculine and girls/feminine, and specific norms direct the children into the dominant feminine and masculine categories, thus maintaining and reinforcing their gender stereotypes. The children used symbols such as colors, locations and types of play as means to instantiate the “girling” and the “boying”. These findings are consistent with previous Nordic research and indicate a prevailing essentialist perspective towards both girls and boys. The originality of the research, however, lies in focusing on children’s gender from the individual’s perspective and how the individual child generally enacts gender performatively within the confines of society’s norms.

    The aim of the study was to assess deep and shallow water teaching methods in swimming lessons for preschool children and identify variations in the basic aquatic skills acquired. The study sample included 32 swimming instructors (16 from deep water programs and 16 from shallow water programs) and 98 preschool children (50 from deep water swimming pool and 48 from shallow water swimming pool). The children were also studied regarding their previous experience in swimming (6, 12 and 18 months or practice). Chi-Square test and Fisher's exact test were used to compare the teaching methodology. A discriminant analysis was conducted with Λ wilk's method to predict under what conditions students are better or worse (aquatic competence). Results suggest that regardless of the non-significant variations found in teaching methods, the water depth can affect aquatic skill acquisition - shallow water lessons seem to impose greater water competence particularly after 6 months of practice. The discriminant function revealed a significant association between groups and all predictors for 6 months of swimming practice (pdeep and shallow water programs for preschoolers is not significantly different. However, shallow water lessons could be preferable for the development of basic aquatic skills.

  7. LEAP into the Pfizer Global Virtual Library (PGVL) space: creation of readily synthesizable design ideas automatically.

    2011-01-01

    Pfizer Global Virtual Library (PGVL) of 10(13) readily synthesizable molecules offers a tremendous opportunity for lead optimization and scaffold hopping in drug discovery projects. However, mining into a chemical space of this size presents a challenge for the concomitant design informatics due to the fact that standard molecular similarity searches against a collection of explicit molecules cannot be utilized, since no chemical information system could create and manage more than 10(8) explicit molecules. Nevertheless, by accepting a tolerable level of false negatives in search results, we were able to bypass the need for full 10(13) enumeration and enabled the efficient similarity search and retrieval into this huge chemical space for practical usage by medicinal chemists. In this report, two search methods (LEAP1 and LEAP2) are presented. The first method uses PGVL reaction knowledge to disassemble the incoming search query molecule into a set of reactants and then uses reactant-level similarities into actual available starting materials to focus on a much smaller sub-region of the full virtual library compound space. This sub-region is then explicitly enumerated and searched via a standard similarity method using the original query molecule. The second method uses a fuzzy mapping onto candidate reactions and does not require exact disassembly of the incoming query molecule. Instead Basis Products (or capped reactants) are mapped into the query molecule and the resultant asymmetric similarity scores are used to prioritize the corresponding reactions and reactant sets. All sets of Basis Products are inherently indexed to specific reactions and specific starting materials. This again allows focusing on a much smaller sub-region for explicit enumeration and subsequent standard product-level similarity search. A set of validation studies were conducted. The results have shown that the level of false negatives for the disassembly-based method is acceptable when the

    Full Text Available Abstract Background This study aimed to compare the levels of objectively-measured sedentary behavior in children attending Montessori preschools with those attending traditional preschools. Methods The participants in this study were preschool children aged 4 years old who were enrolled in Montessori and traditional preschools. The preschool children wore ActiGraph accelerometers. Accelerometers were initialized using 15-second intervals and sedentary behavior was defined as Results Children attending Montessori preschools spent less time in sedentary behavior than those attending traditional preschools during the in-school (44.4. min/hr vs. 47.1 min/hr, P = 0.03, after-school (42.8. min/hr vs. 44.7 min/hr, P = 0.04, and total-day (43.7 min/hr vs. 45.5 min/hr, P = 0. 009 periods. School type (Montessori or traditional, preschool setting (private or public, socio-demographic factors (age, gender, and socioeconomic status were found to be significant predictors of preschoolers’ sedentary behavior. Conclusions Levels of objectively-measured sedentary behavior were significantly lower among children attending Montessori preschools compared to children attending traditional preschools. Future research should examine the specific characteristics of Montessori preschools that predict the lower levels of sedentary behavior among children attending these preschools compared to children attending traditional preschools.

    Currently, cross-sectional imaging viewing is used in routine practice whereas the surgical procedure requires physical contact with an interface (mouse or touch-sensitive screen). This type of contact results in a risk of lack of aseptic control and causes loss of time. The recent appearance of devices such as the Leap Motion(®) (Leap Motion society, San Francisco, USA) a sensor which enables to interact with the computer without any physical contact is of major interest in the field of surgery. However, its configuration and ergonomics produce key challenges in order to adapt to the practitioner's requirements, the imaging software as well as the surgical environment.

The findings suggest that IWB use in preschool is mostly viewed as “Space for children to involve in problem-solving situations”, “Supporting collaborative learning and mutual negotiation”, “Goal-oriented mathematics learning facilitated by IWB” and “Retaining children’s interest in learning activities”. This study also highlights the importance of teachers’ technological knowledge and skills in mediating the interaction and facilitating the use of IWB in preschool pedagogical practices.

This article is the presentation of a research work within the pre-school educational context, in the field of ʻSocial and Personal Educationʼ which may lead to improved social skills within the group of children. In order to accomplish this, after the teaching training with the pre-school class which focussed on the acquisition of social competence, an assessment of the modified social skills within the class was carried out. These activities were included in the preschool lesson planning during the ʻSupervised Teaching Practiceʼ. They were developed based on childrenʼs daily life situations, focussing mainly on using games in the learning contexts. The aim of these games was to motivate and involve the children in order to enhance their balanced social development. The results obtained suggest that the introduction of this type of learning activities may be an asset in Pre-school Education because they develop both childrenʼs social skills and social competence. Moreover, this type of learning activities may also lead to changes in childrenʼs social interaction with both adults and their peers which may favour pro social behaviour.

    Full Text Available This article, written by one of the teachers in the Ypsilanti Perry Preschool Project (1962-1967, critically examines the prevailing narrative about the preschool project’s relationship to the High/Scope Educational Foundation. It describes what the author and other teachers actually did, the principles that informed their practice, and challenges the prevailing myth that the Perry Preschool used the High/ Scope Educational Foundation curriculum. It also discusses what the High/Scope Longitudinal Study did not research about the program, families, and children in the Ypsilanti Perry Preschool and examines possible factors, beyond the curriculum, which effected its positive outcomes. The Perry Preschool Project occurred during the years of the 1960s Civil Rights Movement in the USA, and reflected prevailing ideologies and educational philosophies, some of which were in contention with each other. By bringing the Teachers’ voices to the prevailing discussion, which, to date, is dominated by the Project administrators’ perspective, the article seeks to open up new thinking about the lessons of the Ypsilanti Perry Preschool Project for both early childhood education pedagogy and research.

    Full Text Available Public preschool educational institutions in Slovenia are mostly financed by public money, it means bay state and municipalities. They are also financed by parents. So, it is important that preschool institutions are using public money transparent and responsible, for this reason public preschool institution should have internal controls in financing. The internal auditor as independent professional should verify if internal controls works. The purpose of this paper is to investigate how internal controls in financing public educational institution works it means which internal controls are important in financing the preschool institution - on the selected institution to show and check how internal controls work. For this reason we divide internal controls in the financing in two phases: (1 internal controls in the preparation of the annual financial plan and financial planning of financial resources for institution’s programs and activities, (2 internal controls in obtaining financial resources. We used methods of internal auditing and research approaches as sampling, unstructured interviews and analysis of documents. The results showed that selected preschool institution should work on rules of recovery and monitoring of claims. The findings provide useful academic insight to setting internal controls as well as practical guidance for preschool institutions.

    CO 2 emission from fossil fuels is a major cause for the global warming effect, but it is hard to remove completely in actuality. Moreover, energy consumption is bound to increase for the continuous economic development of a country that has an industrial formation requiring high-energy demand. Therefore, we need to consider not only a device for CO 2 mitigation but also its impact when a CO 2 mitigation device is applied. The device for CO 2 emission mitigation can be classified into three fields: energy consumption reduction, development of CO 2 removal and recovery technology, and development of alternative energy technology. Among these options, CO 2 removal and recovery technology has a merit that can be applied to a process in the near future. Therefore, research for CO 2 removal and recovery is actively progressing in Korea. In this study, environmental and economic assessment according to the energy policy change for climate change agreement and increase of CO 2 mitigation technology is accomplished, on the bases of operating data for the CO 2 chemical absorption pilot plant that is installed in the Seoul coal steam power plant. The Long-range Energy Alternatives Planning system (LEAP) was used to analyze the alternative scenario, and results were shown quantitatively

    Advances in virtual and augmented reality (AR) are having an impact on the medical field in areas such as surgical simulation. Improvements to surgical simulation will provide students and residents with additional training and evaluation methods. This is particularly important for procedures such as the endoscopic third ventriculostomy (ETV), which residents perform regularly. Simulators such as NeuroTouch, have been designed to aid in training associated with this procedure. The authors have designed an affordable and easily accessible ETV simulator, and compare it with the existing NeuroTouch for its usability and training effectiveness. This simulator was developed using Unity, Vuforia and the leap motion (LM) for an AR environment. The participants, 16 novices and two expert neurosurgeons, were asked to complete 40 targeting tasks. Participants used the NeuroTouch tool or a virtual hand controlled by the LM to select the position and orientation for these tasks. The length of time to complete each task was recorded and the trajectory log files were used to calculate performance. The resulting data from the novices' and experts' speed and accuracy are compared, and they discuss the objective performance of training in terms of the speed and accuracy of targeting accuracy for each system.

    Full Text Available Indirana chiravasi, a new species of leaping frog is described from the northern Western Ghats around Amboli, Sindhudurg District, Maharashtra, India. It differs from all its congeners based on a combination of characters including presence of median single internal vocal sac, head longer than wide, distinct canthus rostralis, tympanum 2/3rd to 3/4th the diameter of eye, vomerine teeth in two oblique series at the posterior border of choanae, long midventral lingual papilla, first finger longer than or equal to second, presence of double outer palmer tubercle, thin and elongated inner metatarsal tubercle, absence of outer metatarsal tubercle, webbing moderate, dorsal skin with glandular folds but without warts, ventral skin smooth without mottling and palms and soles dark brown. Molecular analysis based on mitochondrial 12S and 16S genes and nuclear rhodopsin and rag1 genes suggests that the species is genetically distinct from other species for which genetic data is available. Preliminary observations on the development of the species are also provided. We also provide genetic data and images for Indirana gundia collected from the type locality.

    At present, near-surface shear wave velocities are mainly calculated through Rayleigh wave dispersion-curve inversions in engineering surface investigations, but the required calculations pose a highly nonlinear global optimization problem. In order to alleviate the risk of falling into a local optimal solution, this paper introduces a new global optimization method, the shuffle frog-leaping algorithm (SFLA), into the Rayleigh wave dispersion-curve inversion process. SFLA is a swarm-intelligence-based algorithm that simulates a group of frogs searching for food. It uses a few parameters, achieves rapid convergence, and is capability of effective global searching. In order to test the reliability and calculation performance of SFLA, noise-free and noisy synthetic datasets were inverted. We conducted a comparative analysis with other established algorithms using the noise-free dataset, and then tested the ability of SFLA to cope with data noise. Finally, we inverted a real-world example to examine the applicability of SFLA. Results from both synthetic and field data demonstrated the effectiveness of SFLA in the interpretation of Rayleigh wave dispersion curves. We found that SFLA is superior to the established methods in terms of both reliability and computational efficiency, so it offers great potential to improve our ability to solve geophysical inversion problems.

  5. Exploring Direct 3D Interaction for Full Horizontal Parallax Light Field Displays Using Leap Motion Controller

    2015-04-01

    Full Text Available This paper reports on the design and evaluation of direct 3D gesture interaction with a full horizontal parallax light field display. A light field display defines a visual scene using directional light beams emitted from multiple light sources as if they are emitted from scene points. Each scene point is rendered individually resulting in more realistic and accurate 3D visualization compared to other 3D displaying technologies. We propose an interaction setup combining the visualization of objects within the Field Of View (FOV of a light field display and their selection through freehand gesture tracked by the Leap Motion Controller. The accuracy and usefulness of the proposed interaction setup was also evaluated in a user study with test subjects. The results of the study revealed high user preference for free hand interaction with light field display as well as relatively low cognitive demand of this technique. Further, our results also revealed some limitations and adjustments of the proposed setup to be addressed in future work.

  6. Leaping shampoo glides on a 500-nm-thick lubricating air layer

    When a stream of shampoo is fed onto a pool in one's hand, a jet can leap sideways or rebound from the liquid surface in an intriguing phenomenon known as the Kaye effect. Earlier studies have debated whether non-Newtonian effects are the underlying cause of this phenomenon, making the jet glide on top of a shear-thinning liquid layer, or whether an entrained air layer is responsible. Herein we show unambiguously that the jet slides on a lubricating air layer [Lee et al., Phys. Rev. E 87, 061001 (2013)]. We identify this layer by looking through the pool liquid and observing its rupture into fine micro-bubbles. The resulting micro-bubble sizes suggest that the thickness of this air layer is around 500 nm. This thickness estimate is also supported by the tangential deceleration of the jet during the rebounding, with the shear stress within the thin air layer sufficient for the observed deceleration. Particle tracking within the jet shows uniform velocity, with no pronounced shear, which would be required for shear-thinning effects. The role of the surfactant may primarily be to stabilize the air film.

    This paper reports on the design and evaluation of direct 3D gesture interaction with a full horizontal parallax light field display. A light field display defines a visual scene using directional light beams emitted from multiple light sources as if they are emitted from scene points. Each scene point is rendered individually resulting in more realistic and accurate 3D visualization compared to other 3D displaying technologies. We propose an interaction setup combining the visualization of objects within the Field Of View (FOV) of a light field display and their selection through freehand gesture tracked by the Leap Motion Controller. The accuracy and usefulness of the proposed interaction setup was also evaluated in a user study with test subjects. The results of the study revealed high user preference for free hand interaction with light field display as well as relatively low cognitive demand of this technique. Further, our results also revealed some limitations and adjustments of the proposed setup to be addressed in future work.

    Sustainable development is one of the most important challenges for humanity and one of the priorities of the United Nations. Achieving sustainability of the whole World is a main goal of management at all levels - from personal to local to global. Therefore, decision making should be supported by relevant geospatial information system. Nevertheless, classical geospatial products, maps and GIS, violate fundamental demand of `situational awareness' concept, well-known philosophy of decision-making - same representation of situation within a same volume of time and space for all decision-makers. Basic mapping principles like generalization and projections split the universal single model of situation on number of different separate and inconsistent replicas. It leads to wrong understanding of situation and, after all - to incorrect decisions. In another words, quality of the sustainable development depends on effective decision-making support based on universal global scale-independent and projection-independent model. This new way for interacting with geospatial information is a quantum leap in cartography method. It is implemented in the so-called `Digital Earth' paradigm and geospatial services like Google Earth. Com-paring of both methods, as well as possibilities of implementation of Digital Earth in the sustain-able development activities, are discussed.

    After inpatient stroke rehabilitation, many people still cannot participate in community activities because of limited walking ability. To compare the effectiveness of 2 conceptually different, early physical therapy (PT) interventions to usual care (UC) in improving walking 6 months after stroke. The locomotor experience applied post-stroke (LEAPS) study was a single-blind, randomized controlled trial conducted in 408 adults with disabling hemiparetic stroke. Participants were stratified at baseline (2 months) by impairment in walking speed: severe (exercise at home (home exercise program [HEP], n = 126). LTP participants were 18% more likely to transition to a higher functional walking level: severe to >0.4 m/s and moderate to >0.8 m/s than UC participants (95% confidence interval [CI] = 7%-29%), and HEP participants were 17% more likely to transition (95% CI = 5%-29%). Mean gain in walking speed in LTP participants was 0.13 m/s greater (95% CI = 0.09-0.18) and in HEP participants, 0.10 m/s greater (95% CI = 0.05-0.14) than in UC participants. Progressive PT, using either walking training on a treadmill and overground, conducted in a clinic, or strength and balance exercises conducted at home, was superior to UC in improving walking, regardless of severity of initial impairment.

    This study explored how often sound-field amplification and personal frequency-modulated (FM) systems are used in preschool classrooms, teacher perceptions of advantages and disadvantages of using hearing assistive technology, and teacher recommendations for hearing assistive technology use. The study used a cross-sectional survey design. Participants were professionals who provided services to preschool-age children who are deaf or hard of hearing in public or private schools. A total of 306 surveys were sent to 162 deaf education programs throughout the United States; 99 surveys were returned (32%). Simple statistics were used to describe the quantitative survey results; content analysis was completed on open-ended survey comments. Surveys were received from teachers working at listening and spoken language preschool programs (65%) and at bilingual-bicultural and total communication preschool programs (35%). Most respondents perceived that hearing assistive technology improved students' academic performance, speech and language development, behavior, and attention in the classroom. The majority of respondents also reported that they definitely would or probably would recommend a sound-field system (77%) or personal FM system (71%) to other educators. Hearing assistive technology is frequently used in preschool classrooms of children who are deaf or hard of hearing, with generally positive teacher perceptions of the benefits of using such technology.

    2017-09-01

    With a randomized field experiment of 433 preschoolers, we tested a tablet mathematics program designed to increase young children's mathematics learning. Intervention students played Math Shelf, a comprehensive iPad preschool and year 1 mathematics app, while comparison children received research-based hands-on mathematics instruction delivered by their classroom teachers. After 22 weeks, there was a large and statistically significant effect on mathematics achievement for Math Shelf students (Cohen's d = .94). Moderator analyses demonstrated an even larger effect for low achieving children (Cohen's d = 1.27). These results suggest that early education teachers can improve their students' mathematics outcomes by integrating experimentally proven tablet software into their daily routines.

The contract was an optional extension that was initiated on July 21, 1994 and that expired on May 31, 1995. The project manager was Thomas J. Nicholson, Office of Nuclear Regulatory Research. The objectives of this contract were to examine hypotheses and conceptual models concerning unsaturated flow and transport through fractured rock, and to design and execute confirmatory field and laboratory experiments to test these hypotheses and conceptual models at the Apache Leap Research Site near Superior, Arizona. The results discussed here are products of specific tasks that address a broad spectrum of issues related to flow and transport through fractures. Each chapter in this final report summarizes research related to a specific set of objectives and can be read and interpreted as a separate entity. The tasks include detection and characterization of historical rapid fluid flow through fractured rock and the relationship to perched water systems using environmental isotopic tracers of {sup 3}H and {sup 14}C, fluid- and rock-derived {sup 2343}U/{sup 238}U measurements, and geophysical data. The water balance in a small watershed at the ALRS demonstrates the methods of acounting for ET, and estimating the quantity of water available for infiltration through fracture networks. Grain density measurements were made for core-sized samples using a newly designed gas pycnometer.

    Urban hydrology will have an increasing role to play in the sustainability of human settlements. Expansion of urban areas brings significant changes in physical characteristics of landuse. Problems with administration of urban flooding have their roots in concentration of population within a relatively small area. As watersheds are urbanized, infiltration decreases, pattern of surface runoff is changed generating high peak flows, large runoff volumes from urban areas. Conceptual rainfall-runoff models have become a foremost tool for predicting surface runoff and flood forecasting. Manual calibration is often time consuming and tedious because of the involved subjectivity, which makes automatic approach more preferable. The calibration of parameters usually includes numerous criteria for evaluating the performances with respect to the observed data. Moreover, derivation of objective function assosciat6ed with the calibration of model parameters is quite challenging. Various studies dealing with optimization methods has steered the embracement of evolution based optimization algorithms. In this paper, a systematic comparison of two evolutionary approaches to multi-objective optimization namely shuffled frog leaping algorithm (SFLA) and genetic algorithms (GA) is done. SFLA is a cooperative search metaphor, stimulated by natural memetics based on the population while, GA is based on principle of survival of the fittest and natural evolution. SFLA and GA has been employed for optimizing the major parameters i.e. width, imperviousness, Manning's coefficient and depression storage for the highly urbanized catchment of Delhi, India. The study summarizes the auto-tuning of a widely used storm water management model (SWMM), by internal coupling of SWMM with SFLA and GA separately. The values of statistical parameters such as, Nash-Sutcliffe efficiency (NSE) and Percent Bias (PBIAS) were found to lie within the acceptable limit, indicating reasonably good model performance

    The Leap Motion Controller (LMC) is a low-cost, markerless motion capture device that tracks hand, wrist and forearm position. Integration of this technology into healthcare applications has begun to occur rapidly, making validation of the LMC׳s data output an important research goal. Here, we perform a detailed evaluation of the kinematic data output from the LMC, and validate this output against gold-standard, markered motion capture technology. We instructed subjects to perform three clinically-relevant wrist (flexion/extension, radial/ulnar deviation) and forearm (pronation/supination) movements. The movements were simultaneously tracked using both the LMC and a marker-based motion capture system from Motion Analysis Corporation (MAC). Adjusting for known inconsistencies in the LMC sampling frequency, we compared simultaneously acquired LMC and MAC data by performing Pearson׳s correlation (r) and root mean square error (RMSE). Wrist flexion/extension and radial/ulnar deviation showed good overall agreement (r=0.95; RMSE=11.6°, and r=0.92; RMSE=12.4°, respectively) with the MAC system. However, when tracking forearm pronation/supination, there were serious inconsistencies in reported joint angles (r=0.79; RMSE=38.4°). Hand posture significantly influenced the quality of wrist deviation (P<0.005) and forearm supination/pronation (P<0.001), but not wrist flexion/extension (P=0.29). We conclude that the LMC is capable of providing data that are clinically meaningful for wrist flexion/extension, and perhaps wrist deviation. It cannot yet return clinically meaningful data for measuring forearm pronation/supination. Future studies should continue to validate the LMC as updated versions of their software are developed.

  6. An Improved Shuffled Frog Leaping Algorithm and Its Application in Dynamic Emergency Vehicle Dispatching

    Full Text Available The traditional method for solving the dynamic emergency vehicle dispatching problem can only get a local optimal strategy in each horizon. In order to obtain the dispatching strategy that can better respond to changes in road conditions during the whole dispatching process, the real-time and time-dependent link travel speeds are fused, and a time-dependent polygonal-shaped link travel speed function is set up to simulate the predictable changes in road conditions. Response times, accident severity, and accident time windows are taken as key factors to build an emergency vehicle dispatching model integrating dynamic emergency vehicle routing and selection. For the unpredictable changes in road conditions caused by accidents, the dispatching strategy is adjusted based on the real-time link travel speed. In order to solve the dynamic emergency vehicle dispatching model, an improved shuffled frog leaping algorithm (ISFLA is proposed. The global search of the improved algorithm uses the probability model of estimation of distribution algorithm to avoid the partial optimal solution. Based on the Beijing expressway network, the efficacy of the model and the improved algorithm were tested from three aspects. The results have shown the following: (1 Compared with SFLA, the optimization performance of ISFLA is getting better and better with the increase of the number of decision variables. When the possible emergency vehicle selection strategies are 815, the objective function value of optimal selection strategies obtained by the base algorithm is 210.10% larger than that of ISFLA. (2 The prediction error of the travel speed affects the accuracy of the initial emergency vehicle dispatching. The prediction error of ±10 can basically meet the requirements of the initial dispatching. (3 The adjustment of emergency vehicle dispatching strategy can successfully bypassed road sections affected by accidents and shorten the response time.

  7. Cooperation between Parents and Preschool Institutions through Different Concepts of Preschool Education

    2017-12-01

    Full Text Available This paper analyses the importance, role, and methods of cooperation between parents and preschool institutions through the different concepts of preschool education and different educational approaches and formal frameworks. Through educational approaches, the authors analyse how cooperation affects the implementation of preschool education in alternative educational approaches, such as the Waldorf, Montessori, and Reggio Emilia approaches, and Slovenian public preschool institutions. They envisage that different educational approaches in preschool education perceive the importance and role of cooperation with parents differently and conclude that there are various models of cooperation, which can be demonstrated through a theoretical analysis of the aforementioned alternative preschool approaches. In their view, partnership promotes a shared commitment to the quality realisation of educational goals; it also develops understanding and an ethos of openness in the relationship between all actors in the process of care and education of preschool children.

    Martyn, Danika M; McNulty, Breige A; Nugent, Anne P; Gibney, Michael J

    2013-02-01

    Food additives have been used throughout history to perform specific functions in foods. A comprehensive framework of legislation is in place within Europe to control the use of additives in the food supply and ensure they pose no risk to human health. Further to this, exposure assessments are regularly carried out to monitor population intakes and verify that intakes are not above acceptable levels (acceptable daily intakes). Young children may have a higher dietary exposure to chemicals than adults due to a combination of rapid growth rates and distinct food intake patterns. For this reason, exposure assessments are particularly important in this age group. The paper will review the use of additives and exposure assessment methods and examine factors that affect dietary exposure by young children. One of the most widely investigated unfavourable health effects associated with food additive intake in preschool-aged children are suggested adverse behavioural effects. Research that has examined this relationship has reported a variety of responses, with many noting an increase in hyperactivity as reported by parents but not when assessed using objective examiners. This review has examined the experimental approaches used in such studies and suggests that efforts are needed to standardise objective methods of measuring behaviour in preschool children. Further to this, a more holistic approach to examining food additive intakes by preschool children is advisable, where overall exposure is considered rather than focusing solely on behavioural effects and possibly examining intakes of food additives other than food colours.

  13. Wind-powered wheel locomotion, initiated by leaping somersaults, in larvae of the southeastern beach tiger beetle (Cicindela dorsalis media.

    Directory of Open Access Journals (Sweden)

    Alan Harvey

    2011-03-01

    Full Text Available Rapid movement is challenging for elongate, soft-bodied animals with short or no legs. Leaping is known for only a few animals with this "worm-like" morphology. Wheel locomotion, in which the animal's entire body rolls forward along a central axis, has been reported for only a handful of animals worldwide. Here we present the first documented case of wind-powered wheel locomotion, in larvae of the coastal tiger beetle Cicindela dorsalis media. When removed from their shallow burrows, larvae easily can be induced to enter a behavioral sequence that starts with leaping; while airborne, larvae loop their body into a rotating wheel and usually either "hit the ground rolling" or leap again. The direction larvae wheel is closely related to the direction in which winds are blowing; thus, all our larvae wheeled up-slope, as winds at our study site consistently blew from sea to land. Stronger winds increased both the proportion of larvae wheeling, and the distance traveled, exceeding 60 m in some cases. In addition, the proportion of larvae that wheel and the distance traveled by wheeling larvae are significantly greater on smooth sandy beaches than on beach surfaces made rough and irregular by pedestrian, equestrian, and vehicular traffic. Like other coastal species of tiger beetles, C. dorsalis media has suffered major declines in recent years that are clearly correlated with increased human impacts. The present study suggests that the negative effects of beach traffic may be indirect, preventing larvae from escaping from predators using wheel locomotion by disrupting the flat, hard surface necessary for efficient wheeling.

    The long-term forecasting of energy supply and demand is an extremely important topic of fundamental research in Taiwan due to Taiwan's lack of natural resources, dependence on energy imports, and the nation's pursuit of sustainable development. In this article, we provide an overview of energy supply and demand in Taiwan, and a summary of the historical evolution and current status of its energy policies, as background to a description of the preparation and application of a Long-range Energy Alternatives Planning System (LEAP) model of Taiwan's energy sector. The Taiwan LEAP model is used to compare future energy demand and supply patterns, as well as greenhouse gas emissions, for several alternative scenarios of energy policy and energy sector evolution. Results of scenarios featuring 'business-as-usual' policies, aggressive energy-efficiency improvement policies, and on-schedule retirement of Taiwan's three existing nuclear plants are provided and compared, along with sensitivity cases exploring the impacts of lower economic growth assumptions. A concluding section provides an interpretation of the implications of model results for future energy and climate policies in Taiwan. - Research Highlights: > The LEAP model is useful for international energy policy comparison. > Nuclear power plants have significant, positive impacts on CO{sub 2} emission. > The most effective energy policy is to adopt demand-side management. > Reasonable energy pricing provides incentives for energy efficiency and conservation. > Financial crisis has less impact on energy demand than aggressive energy policy.

    2018-01-01

    Kinematic analysis of upper limb reaching provides insight into the central nervous system control of movements. Until recently, kinematic examination of motor control has been limited to studies conducted in traditional research laboratories because motion capture equipment used for data collection is not easily portable and expensive. A recently developed markerless system, the Leap Motion Controller (LMC), is a portable and inexpensive tracking device that allows recording of 3D hand and finger position. The main goal of this study was to assess the concurrent reliability and validity of the LMC as compared to the Optotrak, a criterion-standard motion capture system, for measures of temporal accuracy and peak velocity during the performance of upper limb, visually-guided movements. In experiment 1, 14 participants executed aiming movements to visual targets presented on a computer monitor. Bland-Altman analysis was conducted to assess the validity and limits of agreement for measures of temporal accuracy (movement time, duration of deceleration interval), peak velocity, and spatial accuracy (endpoint accuracy). In addition, a one-sample t-test was used to test the hypothesis that the error difference between measures obtained from Optotrak and LMC is zero. In experiment 2, 15 participants performed a Fitts' type aiming task in order to assess whether the LMC is capable of assessing a well-known speed-accuracy trade-off relationship. Experiment 3 assessed the temporal coordination pattern during the performance of a sequence consisting of a reaching, grasping, and placement task in 15 participants. Results from the t-test showed that the error difference in temporal measures was significantly different from zero. Based on the results from the 3 experiments, the average temporal error in movement time was 40±44 ms, and the error in peak velocity was 0.024±0.103 m/s. The limits of agreement between the LMC and Optotrak for spatial accuracy measures ranged between

  7. The ghost of Afrikaner identity in Ancestral voices, Leap year and The long silence of Mario Salviati (Etienne van Heerden

    Full Text Available Ghost characters are a characteristic of the novels of Etienne van Heerden, but little research has been done concerning the nature and function of these ghost characters. In this article I discuss Van Heerden’s use of ghost characters diachronically with reference to the novels Ancestral voices (1986, Leap year (1993 and The long silence of Mario Salviati (2000. In order to clarify the nature of these ghosts, I use the so-called science of the paranormal as a framework. The ghosts in the three novels will be classified accordingly, and then discussed within the context of the novels in which they appear. In this way, I shall show how the ghost characters in these novels can be read as a constantly changing embodiment of Afrikaner identity (a central theme in Van Heerden’s oeuvre. Van Heerden’s Afrikaner changes with the times: in Ancestral voices the ghost characters form a collective that represents a fragmented image of the stereotypical, archaic male Afrikaner identity; in Leap year a liminal character is written in a liminal time to embody a liminal Afrikaner identity; and in The long silence of Mario Salviati Van Heerden moves away from the exclusive Afrikaner identity to a broader South African identity by using ghost characters from very different backgrounds and origins. In conclusion I shall compare these identities and the historical contexts of these novels in order to show the function of Van Heerden’s ghost characters as constant rewritings of South African identities.

  8. Possible applications of the LEAP motion controller for more interactive simulated experiments in augmented or virtual reality

    Practical exercises are a crucial part of many curricula. Even simple exercises can improve the understanding of the underlying subject. Most experimental setups require special hardware. To carry out e. g. a lens experiments the students need access to an optical bench, various lenses, light sources, apertures and a screen. In our previous publication we demonstrated the use of augmented reality visualization techniques in order to let the students prepare with a simulated experimental setup. Within the context of our intended blended learning concept we want to utilize augmented or virtual reality techniques for stationary laboratory exercises. Unlike applications running on mobile devices, stationary setups can be extended more easily with additional interfaces and thus allow for more complex interactions and simulations in virtual reality (VR) and augmented reality (AR). The most significant difference is the possibility to allow interactions beyond touching a screen. The LEAP Motion controller is a small inexpensive device that allows for the tracking of the user's hands and fingers in three dimensions. It is conceivable to allow the user to interact with the simulation's virtual elements by the user's very hand position, movement and gesture. In this paper we evaluate possible applications of the LEAP Motion controller for simulated experiments in augmented and virtual reality. We pay particular attention to the devices strengths and weaknesses and want to point out useful and less useful application scenarios.

    2013-03-14

    The stochastic integral ensuring the Newton-Leibnitz chain rule is essential in stochastic energetics. Marcus canonical integral has this property and can be understood as the Wong-Zakai type smoothing limit when the driving process is non-Gaussian. However, this important concept seems not well-known for physicists. In this paper, we discuss Marcus integral for non-Gaussian processes and its computation in the context of stochastic energetics. We give a comprehensive introduction to Marcus integral and compare three equivalent definitions in the literature. We introduce the exact pathwise simulation algorithm and give the error analysis. We show how to compute the thermodynamic quantities based on the pathwise simulation algorithm. We highlight the information hidden in the Marcus mapping, which plays the key role in determining thermodynamic quantities. We further propose the tau-leaping algorithm, which advance the process with deterministic time steps when tau-leaping condition is satisfied. The numerical experiments and its efficiency analysis show that it is very promising.

    Full Text Available We present the results of an evaluation of the performance of the Leap Motion Controller with the aid of a professional, high-precision, fast motion tracking system. A set of static and dynamic measurements was performed with different numbers of tracking objects and configurations. For the static measurements, a plastic arm model simulating a human arm was used. A set of 37 reference locations was selected to cover the controller’s sensory space. For the dynamic measurements, a special V-shaped tool, consisting of two tracking objects maintaining a constant distance between them, was created to simulate two human fingers. In the static scenario, the standard deviation was less than 0.5 mm. The linear correlation revealed a significant increase in the standard deviation when moving away from the controller. The results of the dynamic scenario revealed the inconsistent performance of the controller, with a significant drop in accuracy for samples taken more than 250 mm above the controller’s surface. The Leap Motion Controller undoubtedly represents a revolutionary input device for gesture-based human-computer interaction; however, due to its rather limited sensory space and inconsistent sampling frequency, in its current configuration it cannot currently be used as a professional tracking system.

    2017-01-01

    The aim of this study was to assess differences in fundamental motor skills (FMS) proficiency between boys and girls of each age group, independently, across the entire preschool period. Using the Movement Assessment Battery for Children-second edition, FMS proficiency was tested in 325 preschoolers (4.9 ± 1.1 y, range 3-6) using a cross-sectional design. Compared to boys of the same age, 3- and 4-year-old girls had greater total (p skill (p < .01), and balance scores (p < .05). There were no sex differences for total test or balance scores in 5- and 6-year-olds, but 6-year-old boys outperformed girls in aiming and catching (p < .001). These data not only agree with previous research in that sex differences in FMS proficiency exist in preschool children, but the data also show that differences may not be uniform throughout the whole preschool period when analyzing by age. To avoid under- or overestimating FMS proficiency and subsequently prescribing inaccurate motor intervention programs, FMS proficiency normative values should be age- and sex-specific throughout the entire preschool period.

    The purpose of this study was to evaluate the effects of an additional, organized, and more intensive kinesiological treatment on "pure" motor abilities in preschool children. In the present study an experimental treatment was carried out on a sample of 37 preschool boys by applying kinesiological activities. The 60 minute treatment was applied over a period of one school year (9 months), twice a week. A control group of 31 boys were trained according to the regular program for preschool institutions. Treatment effects were assessed by 8 motor ability tests and 5 anthropometric measures. The significant differences between the groups, which were observed after the final measurement and compared to the initial one, proved that the kinesiological treatment had a positive impact on the general development of "pure" motor abilities. The most significant effect of experimental kinesiological treatment was the improvement in whole body force, flexibility and coordination of preschool boys. These findings, obtained only in one school year, point to the importance of physical exercise and the application of additional kinesiological activities with various modalities, to improve motor development, even morphological growth and development in preschool children. The effects of the perennial application of kinesiological activities, under the supervision of kinesiological professionals, could be beneficial and could form the basis for a better biological and motor development in older age.

    This article describes the development, design, and implementation of an integrated randomized double-masked placebo-controlled trial (Project Grow Smart) that examines how home/preschool fortification with multiple micronutrient powder (MNP) combined with an early child-development intervention affects child development, growth, and micronutrient status among infants and preschoolers in rural India. The 1-year trial has an infant phase (enrollment age: 6-12 months) and a preschool phase (enrollment age: 36-48 months). Infants are individually randomized into one of four groups: placebo, placebo plus early learning, MNP alone, and MNP plus early learning (integrated intervention), conducted through home visits. The preschool phase is a cluster-randomized trial conducted in Anganwadi centers (AWCs), government-run preschools sponsored by the Integrated Child Development System of India. AWCs are randomized into MNP or placebo, with the MNP or placebo mixed into the children's food. The evaluation examines whether the effects of the MNP intervention vary by the quality of the early learning opportunities and communication within the AWCs. Study outcomes include child development, growth, and micronutrient status.

    The effects of increases in physical activity (PA) on early literacy skills in preschool children are not known. Fifty-four African-American preschool children from a low socioeconomic urban Head Start participated over 8 months. A 2-group, quasi-experimental design was used with one preschool site participating in the PA intervention and a second site participating as the control site. The PA program was designed to promote 300 minutes/week of moderate to vigorous PA academic lessons. Academic achievement related to early literacy and phonological awareness in the areas of rhyming and alliteration were assessed at baseline, 4 and 8 months. Over 8 months, rhyming significantly (p literacy. © 2016, American School Health Association.

    Interglacial-glacial transitions represent important turnovers in the climate system. In contrast with glacial terminations, they are described as a more gradual cooling. So far, the last interglacial has yielded a wealth of knowledge regarding climate dynamics during past warm periods. On top of the assumed gradual temperature drop starting at 119 ka, evidence for the presence of a drastic drying/cooling event in northern Europe has been observed. In lake records from Germany, a distinct shift in pollen assembly at 117.5 ka is interpreted as the consequence of a short dry event lasting 470 years, defined as the Late Eemian Aridity Pulse (LEAP, Sirocko et al., 2005). In a Belgian stalagmite from Han-sur-Lesse Cave, the LEAP is characterized by a 5‰ increase in δ13C occurring in just 200 years. The δ13C enrichment is dated at 117.5 ka and associated with a vegetation change above the cave, induced by a drying and/or cooling event (Vansteenberge et al., 2016). Also, within North Atlantic sediment cores, an increase in ice rafted debris was linked to the occurrence of a colder period at 117 ka (Irvali et al., 2016). Its coevality with the LEAP indicates a likely more regional extent than previously thought. Up to now, no independent chronology exists and little is known about the continental climatic expression of the LEAP. This study aims at 1) constructing an improved and independent chronology for the LEAP event, 2) characterizing this event in terms of its climatic expression and 3) placing the LEAP within the context of an interglacial-glacial transition. For this, two additional speleothems (Han-8, RSM-17) from two different Belgian caves (Han-sur-Lesse, Remouchamps) are added to the existing Han-9 dataset. Exceptionally high growth rates (0.5 mm yr-1) and a presumed annual layering of the RSM-17 sample enable an annual to decadal resolution to investigate the LEAP. U-Th age models covering the glacial inception are constructed with 25 dates on the three

    Feeding is indicative of the nutritional status of children, however micronutrient deficiency is common in this age group. We evaluated the impact of inclusion of rice (Ultra Rice® (UR®)) fortified with iron, zinc, thiamin and folic acid on laboratory measurements and the nutrient intake of children. Ninety-nine preschoolers (2–6 years; 42.6% male) from two preschools participated, one of which received UR® added to polished rice as part of school meals (test preschool) and the other received only polished rice (control preschool). Biochemical evaluations were performed before and after four months of intervention. Feeding was assessed by direct weighing of food, complemented by 24-h recalls, and the diet was assessed by the Healthy Eating Index (HEI) adapted to the Brazilian reality. The fortified rice improved the levels of zinc (p < 0.001), thiamine (p < 0.001), folic acid (p = 0.003), mean corpuscular hemoglobin (p < 0.001) and mean corpuscular hemoglobin concentration (p < 0.001). The inadequacy percentages of thiamine, folic acid and iron were lower among preschoolers from the test preschool. This study demonstrated the effectiveness of using UR® on laboratory measurements of children. The inadequate intake of thiamine, folic acid and iron was also reduced, making the fortified rice an interesting strategy in school feeding programs. PMID:27187464

    Full Text Available Background: The rapid growth of ICT has led to an important increase in the use of computers in preschool age. However the benefits of this use are a debatable issue. Some focus on the positive effects of computers on learning and kids’ cognitive development while others believe that computers may negatively affect their social and motivational impact.Aim: The aim of this research was to study Greek parents’ views on preschools’ computer programs and how these views are influenced by the family’s socioeconomic level.Methodology: The survey involved 280 parents of children aged 3-5 years, of whom 140 were in the upper socioeconomic level and the other 140 in a lower one.Results: The upper socioeconomic level parents thought that the use of computers was appropriate for preschool children more than parents of lower socioeconomic status (P=0.01. and that its inclusion in the preschool center’s program would work in favor for children who have no computer at home (P=0.00. Parents with higher socioeconomic status felt more than the others that such a program can support the provision of knowledge (P=0.00, the development of mathematical (P=0.00 and linguistic skills (P=0.00 and entertain children (P=0.04. Furthermore, the upper socioeconomic level parents as opposed to the other group do not consider that the computer will remove preschool educator from their leading and teaching role (P=0.04 or reduce their communication with the preschoolers (P=0.00.Conclusions: The results of this study revealed that Greek parents, especially those of higher socioeconomic level, have a positive view on the integration of a computer program into the preschoolclassroom.

    Television viewing has been associated with increased violence in play and higher rates of obesity. Although there are interventions to reduce television viewing by school-aged children, there are none for younger children. To develop and evaluate an intervention to reduce television viewing by preschool children. Randomized controlled trial conducted in 16 preschool and/or day care centers in rural upstate New York. Children aged 2.6 through 5.5 years. Children attending intervention centers received a 7-session program designed to reduce television viewing as part of a health promotion curriculum, whereas children attending the control centers received a safety and injury prevention program. Change in parent-reported child television/video viewing and measured growth variables. Before the intervention, the intervention and control groups viewed 11.9 and 14.0 h/wk of television/videos, respectively. Afterward, children in the intervention group decreased their television/video viewing 3.1 h/wk, whereas children in the control group increased their viewing by 1.6 h/wk, for an adjusted difference between the groups of -4.7 h/wk (95% confidence interval, -8.4 to -1.0 h/wk; P =.02). The percentage of children watching television/videos more than 2 h/d also decreased significantly from 33% to 18% among the intervention group, compared with an increase of 41% to 47% among the control group, for a difference of -21.5% (95% confidence interval, -42.5% to -0.5%; P =.046). There were no statistically significant differences in children's growth between groups. This study is the first to show that a preschool-based intervention can lead to reductions in young children's television/video viewing. Further research is needed to determine the long-term effects associated with reductions in young children's television viewing.

    Full Text Available Strategies to early develop and implement motor skill promotion in preschoolers are lacking. Thus, we examined the effects of a card-based exercise promotion program in a kindergarten setting. 214 preschool children (5.5 ± 0.6 y, range 4.2–6.7 y were examined in the present intervention study. Body mass index (BMI and waist circumference were measured. Children were randomly assigned to the KIDZ-Box® physical activity intervention program (INT: n = 107 or the control group (CON: n = 107. Children were trained daily for 15 min over 7 month at the preschool for agility, balance, endurance and jump performance, employing the card-based KIDZ-Box® media package. At pre- and post-testing, dynamic balance, jump and agility performance were tested. Cross-sectionally, agility testing differed between sexes (p = 0.01 and BMI (p = 0.02. Trends towards a significant association were found between BMI and side-to-side jumping (p = 0.1 and beam balancing (p = 0.05. Relevant interventional effects favoring the intervention group were slightly found for agility (p = 0.04, ηp2 = 0.02 and moderately for side-to-side jumping (p < 0.001, ηp2 = 0.08. Balance performance did not relevantly improve. As jumping cards have been used frequently by the teachers, jumping improvements are plausible. The activity cards are feasibly applicable but should be employed with more structure during longer training sessions.

    2010-12-01

    Letter knowledge is a key aspect of children's language development, yet relatively little research has aimed to understand the nature of lowercase letter knowledge. We considered 4 hypotheses about children's lowercase letter knowledge simultaneously--uppercase familiarity, uppercase-lowercase similarity, own-name advantage, and frequency in printed English--as well as 3 interactions. Participants were 461 children ranging in age from 3 to 5 years, all of whom attended public preschool programs serving primarily children from low-income homes, who completed a letter naming task. Uppercase familiarity was the strongest predictor of children's lowercase alphabet knowledge; children were more than 16 times more likely to know a lowercase letter if they knew the corresponding uppercase letter. Uppercase-lowercase similarity and frequency in printed English also predicted children's lowercase letter knowledge, as did the interaction between uppercase familiarity and own-name advantage and the interaction between uppercase familiarity and uppercase-lowercase similarity. Findings suggest that transference from uppercase letter knowledge may be a primary mechanism for lowercase letter knowledge and that young children's knowledge of the lowercase alphabet letters is multiply determined.

    2016-04-01

    Compared with their higher-income counterparts, children growing up in low-income families in the United States typically complete less schooling, report worse health, and work and earn less in adulthood. Moreover, changes in the American economy over the last 40 years have raised the level of skills and qualifications that children need to obtain a good middle-class job, as well as making it much more difficult for children from low-income families to attend schools that support their learning of these skills. We first review strategies used in the past to improve K-12 schooling-including investing more money, introducing more accountability, and putting in place new governance structures (eg, charter schools)-and show why these strategies have been relatively ineffective. Drawing on the research literature and case studies, we then describe education reform strategies for prekindergarten programs and for elementary, middle, and high schools that may help meet these challenges. All of the initiatives described in our case studies provide ample opportunities for teachers and school leaders to improve their skills through coaching and other professional development activities; incorporate sensible systems of accountability, including requiring teachers to open their classrooms to the scrutiny of colleagues and school leaders and to work with their colleagues to improve their teaching practices; and incorporate high academic standards, such as those described in the Common Core State Standards. By focusing directly on improving teaching and promoting learning, these successful initiatives have boosted the achievement of low-income children. They show that it is indeed possible to make a real difference in the life chances of low-income children. Copyright © 2016 Academic Pediatric Association. Published by Elsevier Inc.

    2012-01-01

    Full Text Available The aim of the study was to analyze the presence of stress-related health problems among preschool employees and the way in which these reactions are related to noise and other work parameters. The investigation included 101 employees at 17 preschools in Umeå County, located in northern Sweden. Individual noise recordings and recordings in dining rooms and play halls were made at two departments from each preschool. The adverse effects on the employees were analyzed by use of different validated questionnaires and by saliva cortisol samples. Stress and energy output were pronounced among the employees, and about 30% of the staff experienced strong burnout syndromes. Mental recovery after work was low, indicated by remaining high levels of stress after work. The burnout symptoms were associated with reduced sleep quality and morning sleepiness. Cortisol levels supported the conclusion about pronounced daily stress levels of the preschool employees.

    2004-03-01

    The sodium-water reaction event in an FBR steam generator (SG) has influence on the safety, economical efficiency, etc. of the plant, so that the selection of design base leak (DBL) of the SG is considered as one of the important matters. The clarification of the sodium-water reaction phenomenon and the development of an analysis model are necessary to estimate the sodium-water reaction event with high accuracy and rationality in selecting the DBL. The reaction jet model is pointed out as a part of the necessary improvements to evaluate the overheating tube rupture of large SGs, since the behavior of overheating tube rupture is largely affected by the reaction jet conditions outside the tube. Therefore, LEAP-JET has been developed as an analysis code for the simulation of sodium-water reactions. This document shows the validation of the LEAP-JET code by the Sodium-Water Reaction Test (SWAT-1R). The following results have been obtained: (1) The reaction rate constant, K, is estimated at between 0.001≤K≤0.1 from the LEAP-JET analysis of the SWAT-1R data. (2) The analytical results on the high-temperature region and the behaviors of reaction consumption (Na, H 2 O) and products (H 2 , NaOH, Na 2 O) are considered to be physically reasonable. (3) The LEAP-JET analysis shows the tendency of overestimation in the maximum temperature and temperature distribution of the reaction jet. (4) In the LEAP-JET analysis, the numerical calculation becomes unstably, especially in the mesh containing quite small sodium mass. Therefore, it is necessary to modify the computational algorism to stabilize it and obtain the optimum value of K in sodium-water reactions. (author)

    The concentrations of Cr, Cu, Fe, Mn, Ni, Pb, Cd, and Zn were determined in the brain, heart, liver, gill, gonad, spleen, kidney, and red and white muscles of Liza saliens (leaping mullet). Trace element levels in fish samples were analyzed by flame atomic absorption spectrometry. Among the non-essential metals, the levels of Ni and Pb in the tissues were higher than limits for fish proposed by FAO/WHO, EU, and TFC. Generally, the levels of the non-essential metals were much higher than those of manganese in the red and white muscles. Fe distribution pattern in tissues was in order of spleen > liver > heart > gill > brain > kidney > gonad > red muscle > white muscle. Red muscle was not within the safe limits for human consumption because non-essential metal (Ni, Pb) contents were higher than standard limits.

    Full Text Available Increased noise, which is also below the occupational exposure values and is “hearing safe” noise, affects the exposed person’s health as a non-specific stressor. Increased noise level also creates an environment for additional vocal apparatus load. The objective of this study was to determine preschool personnel occupational noise and its relationship with subjective health complaints. Data were obtained with survey assistance through subjective answers of respondents about health complaints and noise exposure among Rīga preschool personnel. Objective noise measurements were made to assess real noise levels in the preschool environment. Data from 155 respondents and objective measurements of 37 preschool classrooms were obtained. The results showed that the average 8-h noise exposure among Rīga preschool educational institutions was 70 dB(A, which did not exceed the Latvian work environment noise limits, but exceeded the 35–40 dB(A noise limit in the educational environment guidelines recommended by the WHO. The survey results showed that loud noise is one of the most important workplace environmental factors (~70% of respondents feel a necessity to increase voice because of noise. A constant feeling of fatigue, headache, irritable feeling, and a desire to isolate oneself from others more often occurred in respondents exposed to increased noise, compared with those who noted that they were not exposed to increased noise. In general, loud noise was associated with increased subjective health complaints in preschool education institution personnel.

    The Dutch government considers the transition process to be necessary and stimulates investments in energy innovations in the built environment. This innovation effort is the programme 'Energy Leap' (Energiesprong), which is being carried out by the Steering Group Experimental Housing (SEV) on behalf of the Dutch Ministry of the Interior and Kingdom Relations (BZK). The programme is derived from the Innovation Agenda for Energy in the Built Environment. The examples in this book are intended to inspire (potential) participants in the Experiment Energy Leap for Small-scale Urban Areas. The examples focus explicitly on the reduction of CO2 emissions in urban areas, and thus, in addition to CO2 reduction on a building level, the aspects of energy supply, (local) energy production and the energy infrastructure [Dutch] Het SEV-programma Energiesprong (SEV is Stuurgroep Experimenten Volkshuisvesting) beoogt een substantiele bijdrage te leveren aan de condities waaronder de energietransitie effectief tot stand kan komen.

  14. Long-term scenario alternatives and their implications: LEAP model application of Panama's electricity sector

    International Nuclear Information System (INIS)

    McPherson, Madeleine; Karney, Bryan

    2014-01-01

    Panama recently enacted a new law, which aims to promote wind energy by mandating long term power purchase tenders. The implications of this new law lend some uncertainty to Panama's electricity development pathway. This paper quantitatively analyzes the current status of power generation in Panama, and explores various potential future scenarios and the associated impacts on the system marginal cost, global warming potential, and resource diversity index. To this end, this study applies the scenario development methodology developed by Schwartz in the context of the energy-economic modeling platform ‘Long-range Energy Alternative Planning’ (LEAP). Four scenarios are developed and analyzed. The Business as Usual scenario extrapolates the electricity generation trend that has been observed over the last decade; it is compared to three alternative scenarios which have more specific objectives. Scenario 1 encourages climate mitigation without incorporating new technologies in the generation mix, Scenario 2 maximizes resource diversity, and Scenario 3 minimizes global warming potential. For each scenario, the composition of the electricity generation profile, system marginal cost, global warming potential, and resource diversity is predicted quantitatively. These scenarios to not attempt to forecast likely developments, but rather illuminate the tradeoffs that different development pathways entail. - Highlights: • This paper models Panama's electricity sector using the LEAP model platform. • Four scenarios are developed and analyzed. • Impact analysis includes: system cost, global warming potential, resource diversity index. • Panama can achieve a sustainable grid with existing technologies and costs. • There is an tradeoff between the resource diversity and global warming potential

    The leap motion controller (LMC) is a new optoelectronic system for capturing motion of both hands and controlling a virtual environment. Differently from previous devices, it optoelectronically tracks the fine movements of fingers neither using glows nor markers. This pilot study explored the feasibility of adapting the LMC, developed for videogames, to neurorehabilitation of elderly with subacute stroke. Four elderly patients (71.50 ± 4.51 years old) affected by stroke in subacute phase were enrolled and tested in a cross-over pilot trial in which six sessions of 30 minutes of LMC videogame-based therapy were added on conventional therapy. Measurements involved participation to the sessions, evaluated by means of the Pittsburgh Rehabilitation Participation Scale, hand ability and grasp force evaluated respectively by means of the Abilhand Scale and by means of the dynamometer. Neither adverse effects nor spasticity increments were observed during LMC training. Participation to the sessions was excellent in three patients and very good in one patient during the LMC trial. In this period, patients showed a significantly higher improvement in hand abilities (P = 0.028) and grasp force (P = 0.006). This feasibility pilot study was the first one using leap motion controller for conducting a videogame-based therapy. This study provided a proof of concept that LMC can be a suitable tool even for elderly patients with subacute stroke. LMC training was in fact performed with a high level of active participation, without adverse effects, and contributed to increase the recovery of hand abilities.

    Lloyd, Sharon Henry

    In the United States, a current initiative, Advancing Active STEM Education for Our Youngest Learners, aims to advance science, technology, engineering, and math (STEM) education in early childhood. The purpose of this study was to understand preschool teachers' proficiency with science and address the problem of whether or not science learning opportunities are provided to young children based on teachers' attitudes and beliefs. A theoretical framework for establishing teachers' attitudes toward science developed by van Aalderen-Smeets, van der Molen, and Asma, along with Bandura's theory of self-efficacy were the foundations for this research. Research questions explored preschool teachers' attitudes and beliefs toward science in general and how they differed based on education level and years of preschool teaching experience. Descriptive comparative data were collected from 48 preschool teacher participants using an online format with a self-reported measure and were analyzed using nonparametric tests to describe differences between groups based on identified factors of teacher comfort, child benefit, and challenges. Results indicated that the participants believed that early childhood science is developmentally appropriate and that young children benefit from science instruction through improved school-readiness skills. Preschool teachers with a state credential or an associate's degree and more teaching experience had more teacher comfort toward science based on attitudes and beliefs surveyed. The data indicated participating preschool teachers experienced few challenges in teaching science. The study may support positive social change through increased awareness of strengths and weaknesses of preschool teachers for the development of effective science professional development. Science is a crucial component of school-readiness skills, laying a foundation for success in later grades.

    The purpose of this cross-cultural study was to describe and compare US and Turkish children's observational knowledge of the day and night cycle and to identify similarities predicted by framework theory. Fifty-six (27 US and 29 Turkish) young children (ages 48-60 months) participated in the study. Semi-structured interviews were individually conducted, digitally recorded, transcribed, and analyzed using the constant comparative method. The results demonstrate that preschoolers from the two cultures are able to make comparable informal observations of the sky, and their observational knowledge includes many similarities, with one exception, as predicted by framework theory. US children were more likely to perform better than the Turkish children on the question about the time of observation for the moon. Although science concepts and skills are better represented in US early childhood education programs than the Turkish program, the results suggest that this advantage did not translate into performance differences between US and Turkish children.

    1976-10-14

    The behavior of 24 children, aged 3-6 years, was recorded on video-tape. Simultaneously the ECG was recorded telemetrically. These observations were made during two pre-school educational programs lasting 90 minutes each: "Didactic games" and "Elementary music and movement program". For each child a scale was developed to show the correlation of mean heart-rate and well defined motor-activity. It was evident that the mean heart-rate was higher during the music program than during the didactic program, corresponding to the higher motor-activity. But it was found that in the didactic program the variation of the heart-rate within short intervals was higher due to the more frequent occurrence of respiratory arrhythmias. It was also seen that during the music program the children showed no signs of exertion as they did towards the end of the didactic program. Respiratory arrhythmias were not seen in children who according to the Schellong-test were classified as stable in their cardiovascular system. The arrhythmias occurred mainly when the children showed signs of fatigue.

  17. New Mexico Fiber-Optic Link Marks Giant Leap Toward Future of Radio Astronomy

    1998-12-01

    SOCORRO, NM -- Scientists and engineers at the National Radio Astronomy Observatory (NRAO) have made a giant leap toward the future of radio astronomy by successfully utilizing the Very Large Array (VLA) radio telescope in conjunction with an antenna of the continent-wide Very Long Baseline Array (VLBA) using the longest fiber-optic data link ever demonstrated in radio astronomy. The 65-mile fiber link will allow scientists to use the two National Science Foundation (NSF) facilities together in real time, and is the first step toward expanding the VLA to include eight proposed new radio-telescope antennas throughout New Mexico. LEFT: Miller Goss, NRAO's director of VLA/VLBA Operations, unveils graphic showing success of the Pie Town-VLA fiber link. The project, funded by the NSF and Associated Universities, Inc. (AUI), which operates NRAO for the NSF, links the VLA and the VLBA antenna in Pie Town, NM, using a Western New Mexico Telephone Co. fiber-optic cable. The successful hookup was announced at a ceremony that also marked the 10th anniversary of NRAO's Operations Center in Socorro. "Linking the Pie Town antenna to the VLA quadruples the VLA's ability to make detailed images of astronomical objects," said Paul Vanden Bout, NRAO's Director. "This alone makes the link an advance for science, but its greater importance is that it clearly demonstrates the technology for improving the VLA's capabilities even more in the future." "Clearly, the big skies and wide open spaces in New Mexico create near perfect conditions for the incredible astronomical assets located in our state. This new fiber-optic link paves the way for multiplying the already breathtaking scientific capabilities of the VLA," Senator Pete Domenici (R-NM) said. The VLA is a system of 27 radio-telescope antennas distributed over the high desert west of Socorro, NM, in the shape of a giant "Y." Made famous in movies, commercials and numerous published photos, the VLA has been one of the most productive

  18. The Discourse of a Preschool Education Curriculum

    Lidija Miškeljin

    2016-02-01

    Full Text Available The paper presents a critical analysis of the discourse of a preschool education curriculum. Its starting point is Foucault’s concept of discourse as language in use, which not only reflects the social order, but also shapes it through a network of conventions, knowledge and practices determining man’s – or, in this case, the reader’s – perception of reality. The analysis is based on identifying the discourse strategies and/or systems of rules laid out in the text The basic principles of the preschool education curriculum for three- to seven-year-old children – model A which make possible certain statements and insights regarding children and thus position the child and the preschool teacher by means of discourse repertoires. This approach helps contextualize the text and leads to an understanding of the basic discourse mechanism involved in the creation of specific versions of preschool education. As discourse analysis itself is related to interpretation and narratology, with the story as a constant, so is this paper a story about a preschool curriculum, for, like any other text, it tells an unfinished story that can yet evolve in different directions.

    Full Text Available Preschool upbringing of children with developmental difficulties is the first link in the system of education and upbringing and at the same time the utmost segment in the system of integrational rehabilitation.Initiating the process of preschool upbringing and adequate organized treatment at early age, permits support of the development and maximum usage of the remained capabilities of children with developmental difficulties.The newest world experiences show that the upbringing and educational integration of children with developmental difficulties as asegment of the social integration, should set the main conditions in the frames of upbringing education and rehabilitational continuity and support the minimal restrictive environment for their development.In the pre-school institutions that function on the territory of the Republic of Macedonia, an indifferent attitude towards the children with developmental difficulties is present, due to the uninformed educators for the characteristics and capabilities of these children and their believes for the negative influence of the children with developmental difficulties on the children without impairments, that implicates involvement of subsidery defectological education of present employed staff in the mainstream preschool institutions, also including defectologists in kindergartens for work with children with special difficulties in their development. Also, the data about the educator’s attitude in the mainstream preschool institutions is disturbing, so that they put the accent on the obligation for reducing of the program for work with handicapped children, not taking into consideration that subsidery, special forms and methods are needed beside the programs that are for the main stream group.The goal of our paper is to point out the need of involving of children with light developmental difficulties; the existence of special team in the preschool institutions when involving children with
