    abstractThis book is a beginning. It begins to explore three conditions. First is the idea of the boundary - not simply the boundary as something that fixes limits, but as something that defines the spatial qualities of architecture. For example, a space that has four opaque walls, a dark floor and a heavy ceiling will feel like a closed cell. But what if the ceiling doesn't quite complete the boundary of the box, and instead it pulls away from the walls to let in traces of daylight. T...

    2012-11-01

    This article discusses the development of beginning physics teachers' pedagogical content knowledge (PCK) in the context of teaching basic electricity during a one-year Professional Graduate Diploma in Education (PGDE) course and beyond. This longitudinal study used repeated semi-structured interviews over a period of four-and-a-half years. The interview schedule followed a line of development through the secondary school electrical syllabus in Scotland. Fifteen student teachers were interviewed during the PGDE year. Six of them were followed up at the end of the Induction Year (their first year as newly qualified teachers) and again two-and-a-half years later. Thematic analysis of the interviews showed that before the beginning teachers had taught any classes, their initial focus was on how to transform their own subject matter knowledge (SMK) about electricity into forms that were accessible to pupils. As the beginning teachers gained experience working with classes, they gave vivid descriptions of interacting with particular pupils when teaching electricity, which showed the development of their PCK. This played a significant role in the teachers' change of focus from teaching physics to teaching children as they transformed their SMK into forms that were accessible to pupils and developed their own general pedagogical knowledge.

    Parenting style may have a role in the development of young children's dietary behaviour, and a better understanding of parenting style may lead to better-targeted childhood obesity prevention interventions. This study aimed to investigate the association of parental self-efficacy, parenting style and dietary behaviour of young children. A cross-sectional study with 242 first-time mothers and their children was conducted using the data from the Healthy Beginnings Trial undertaken in one of the most socially and economically disadvantaged areas of south-western Sydney, in 2007-2010. Parental self-efficacy, parenting style (warmth and hostility) and children's dietary behaviours (consumption of vegetables, fruit, soft-drink and snacks) were assessed by face-to-face interviews with participating mothers in the control group when their children were 2 years old. Logistic regression analysis was conducted to examine the association between parenting style and the child's dietary behaviour. Mothers with higher levels of global parental self-efficacy and self-efficacy for an infant were more likely to report their children had 2 serves of vegetables per day, with odds ratio (OR) 2.40 (95%CI 1.35-4.27, P=0.003) and OR 1.88 (95%CI 1.06-3.36, P=0.03), respectively. A higher level of global parental self-efficacy or self-efficacy for an infant was significantly associated with having 2 serves of fruit per day with adjusted odds ratio (AOR) 2.46 (95%CI 1.35-4.48, P=0.003) and AOR 1.85 (95%CI 1.00-3.41, P=0.048), respectively, after adjusting for annual household income. Mothers with a higher level of parental warmth were more likely to report their children had 2 serves of vegetable per day with OR 1.85 (95%CI 1.06-3.25, P=0.03). Parental self-efficacy and parenting style were associated, cross-sectionally, with important children's dietary behaviours. Interventions which target parental self-efficacy and parenting style may improve eating habits of young children, and

    In children with no prior history of abdominal surgery and no signs of intussusception or incarcerated inguinal hernia, mechanical ileus may have a congenital cause such as malrotation with volvulus or a persistent omphalomesenteric duct. Acquired causes include sigmoid volvulus. We present two cases of mechanical ileus in children. The first case involved a 6-year-old boy who presented with acute abdominal pain and vomiting. An emergency laparotomy was performed, with resection of the omphalomesenteric duct. Recovery was uneventful. The other case concerned a 9-year-old boy who presented with increasing abdominal pain, bilious vomiting and general clinical deterioration. An emergency laparotomy was performed, revealing malrotation with volvulus and intestinal ischaemia. Children with no prior abdominal history who present with symptoms that may be caused by mechanical obstruction should be managed with a view to surgery and without delay, in order to prevent a catastrophic outcome resulting from a congenital or acquired mechanical obstruction.

    Full Text Available BACKGROUND: The primary objective was to describe infectious complications in children with acute myeloid leukemia from presentation to the healthcare system to initiation of chemotherapy and to describe how these infections differ depending on neutropenia. METHODS: We conducted a retrospective, population-based cohort study that included children and adolescents with acute myeloid leukemia diagnosed and treated at 15 Canadian centers. We evaluated infections that occurred between presentation to the healthcare system (for symptoms that led to the diagnosis of acute myeloid leukemia until initiation of chemotherapy. RESULTS: Among 328 children, 92 (28.0% were neutropenic at presentation. Eleven (3.4% had sterile-site microbiologically documented infection and four had bacteremia (only one Gram negative. Infection rate was not influenced by neutropenia. No child died from an infectious cause prior to chemotherapy initiation. CONCLUSION: It may be reasonable to withhold empiric antibiotics in febrile non-neutropenic children with newly diagnosed acute myeloid leukemia until initiation of chemotherapy as long as they appear well without a clinical focus of infection. Future work could examine biomarkers or a clinical score to identify children presenting with leukemia and fever who are more likely to have an invasive infection.

    One of the greatest challenges facing augmentative and alternative communication (AAC) professionals is providing children with complex communication needs with access to the vocabulary that they need in order to develop mature language and literacy abilities. The purpose of this study was to analyze the vocabulary used by typically developing early-elementary children in the United States and New Zealand when they write about self-selected topics, in order to inform practices with children with complex communication needs. The children's writing samples were compared across school ages and countries. The school age comparisons highlighted the relatively restricted range of vocabulary used by children in the earliest stages of writing development, and the country comparisons revealed differences in core vocabulary. The findings of this study hopefully will assist AAC professionals as they engage in selecting, prioritizing, and organizing vocabulary to support written language development in children with complex communication needs.

    BACKGROUND: Delivery of a boy has been reported to increase a woman's risk of recurrent miscarriage in subsequent pregnancies. We explored whether delivery of boys similarly increases the risk of a subsequent stillbirth. METHODS: We identified all Danish women delivering their first child...... (singleton) between 1980 and 1998 (n = 499,731) using the Danish Birth Registry. These women had subsequent singleton births through 2004 (n = 558,314). We assessed the risk of stillbirth conditional on sex of prior children. RESULTS: The risk of stillbirth was increased by 12% after deliver of boys compared...... with girls (relative risk = 1.12 [95% confidence interval = 1.02-1.23]). This association did not appear to be explained by maternal confounders. CONCLUSION: Stillbirth risk appears to be slightly higher among the pregnancies of women who have previously delivered a boy. One possible mechanism is maternal...

    BACKGROUND: It has been proposed that infections in infancy and early childhood are associated with a reduced risk of childhood acute lymphoblastic leukaemia (ALL). We tested this hypothesis in a register-based study of hospitalisations for infectious diseases prior to diagnosis of childhood ALL....... PROCEDURE: A nation-wide cohort encompassing all Danish children aged 0-14 years and born between 1977 and 2008 (N = 1,778,129) was established and followed for hospitalisations for infectious diseases and risk of childhood ALL. The exposure was lagged 1 year to limit reverse causality. In the statistical...... hospitalisations for infectious diseases before (incidence rate ratio = 0.92, 95% confidence interval 0.78-1.07) nor at/after 2 years of age (incidence rate ratio = 1.04, 95% confidence interval 0.81-1.32). This also applied to subsets of ALL supposedly initiated prenatally. CONCLUSION: The absence of association...

    Several studies comparing adult musicians and non-musicians have provided compelling evidence for functional and anatomical differences in the brain systems engaged by musical training. It is not known, however, whether those differences result from long-term musical training or from pre-existing traits favoring musicality. In an attempt to begin addressing this question, we have launched a longitudinal investigation of the effects of childhood music training on cognitive, social and neural development. We compared a group of 6- to 7-year old children at the start of intense after-school musical training, with two groups of children: one involved in high intensity sports training but not musical training, another not involved in any systematic training. All children were tested with a comprehensive battery of cognitive, motor, musical, emotional, and social assessments and underwent magnetic resonance imaging and electroencephalography. Our first objective was to determine whether children who participate in musical training were different, prior to training, from children in the control groups in terms of cognitive, motor, musical, emotional, and social behavior measures as well as in structural and functional brain measures. Our second objective was to determine whether musical skills, as measured by a music perception assessment prior to training, correlates with emotional and social outcome measures that have been shown to be associated with musical training. We found no neural, cognitive, motor, emotional, or social differences among the three groups. In addition, there was no correlation between music perception skills and any of the social or emotional measures. These results provide a baseline for an ongoing longitudinal investigation of the effects of music training. PMID:25249961

  9. Regulatory examination of the radiation-hygienic situation at Sites of Temporary Storage in North-West Russia prior to the beginning of major spent fuel removal works

    International Nuclear Information System (INIS)

    The paper describes a regulatory project carried out, under a collaborative agreement between the Federal Medical-Biological Agency of the Russian Federation (FMBA) and the Norwegian Radiation Protection Authority (NRPA), by the Institute of Biophysics (Technical Support Organisation to FMBA) and western specialists. The project is one several addressing aspects of the management of spent fuel and radioactive waste at Sites of Temporary Storage (STSs) operated by Federal Enterprise SevRAO at Andreeva Bay and Gremikha on the Kola Peninsula in North-West Russia, and the decommissioning of the sites. Industrial and regulatory projects are addressing options for removing spent submarine fuel currently stored in poor conditions at the sites and moving it to more appropriate storage facilities. The work described in this paper was to review and collate independent data on the current radiation situation and radiation control in the areas at and around the sites. The project has the ultimate objectives to develop norms and standards and supporting regulatory guidance for application during and upon completion of rehabilitation of Andreeva Bay and Gremikha, and this work provides a 'baseline' of radiation conditions, before operations begin to remove the spent fuel. The examination identified and prioritised areas of contamination on and around the sites in terms of their current significance for the safety and health of workers and the public and their possible future significance for the environment and potential future users of the sites. Some areas on the sites had high dose rates - up to about 140 μSv/h in Andreeva Bay and 8500 μSv/h in Gremikha - due to contamination from past spent fuel storage practices. Although there do not appear currently to be areas of severe contamination outside the sites, some of the contamination on-site is in forms that will migrate with time, for example in streams and marine sediments.

  10. Children's Faithfulness in Imitating Language Use Varies Cross-Culturally, Contingent on Prior Experience.

    Klinger, Jörn; Mayor, Julien; Bannard, Colin

    2016-05-01

    Despite its recognized importance for cultural transmission, little is known about the role imitation plays in language learning. Three experiments examine how rates of imitation vary as a function of qualitative differences in the way language is used in a small indigenous community in Oaxaca, Mexico and three Western comparison groups. Data from one hundred thirty-eight 3- to 10-year-olds suggests that children selectively imitate when they understand the function of a given linguistic element because their culture makes frequent use of that function. When function is opaque, however, children imitate faithfully. This has implications for how children manage the imitation-innovation trade-off, and offers insight into why children imitate in language learning across development. PMID:27189408

    BACKGROUND: Tunneled central venous catheters (CVCs) are inevitable in children with acute lymphoid leukemia (ALL). The aim of this study was to evaluate the risk of CVC-related complications in children with ALL in relation to timing of catheter placement and type of catheter. PROCEDURE: All...... children hospitalized from January 2000 to March 2008 with newly diagnosed ALL and with double-lumen total implantable devices (TIDs) or tunneled external catheters (TEs) were included retrospectively. We only used data related to the patient's first catheter. RESULTS: We included 98 children; 35 received...... a TID and the remaining 63 received a TE. A total number of 29,566 catheter days and 93 catheter-associated blood stream infections (CABSI) was identified. We found a CABSI rate of 3.1/1,000 catheter days (5.4/1,000 catheter days for TEs and 1.4/1,000 catheter days for TIDs, incidence rate ratio (IRR) 3...

  12. Children of parents irradiated prior to conception - a longterm study (results 1986)

    International Nuclear Information System (INIS)

    Five or ten years after a first examination, 55 children were submitted to a check-up investigation of their physical and intellectual development. The group of twenty irradiated fathers received an average dose to the gonads of 0.55 Gy (0.01 to 6.4 Gy), the group of twenty irradiated mothers 0.72 Gy (0.01 to 8.0 Gy). In all parents the most frequent finding was Hodgkin's disease, which was diagnosed as a neoplams in 23 cases. The proof of paternity was made with a 86% accuracy for ten out of twenty fathers by determination of HLA types. A conception was demonstrated beyond all doubt after a dose to the testicles of 1.2 Gy in the irradiated fathers and after a dose to the ovaries of 3.0 Gy in the irradiated mothers. The offspring of the F1 generation showed no modification in the sex ratio. A rate of 5.5% of severe malformations was found (trisomy E, bradyacousia of the inner ear, cleft hands and feet). 24% of the children had malformations which needed a treatment (hernias, torticollis, hip dysplasia). 18 out of 55 children (33%) presented abnormalities in the widest sense of the word. Three children (5.5%) were premature infants, and there is a general tendency towards shortened pregnancy (-3.6 days). Hernias (7/55) are a frequent finding. In children of both sexes, carporadiography shows a delayed development which is not compensated in the check-up examinations at five or ten years, but does not cause an underdevelopment in body height as compared to great normal collectives. The results suggest a slightly increased malformation rate among children whose parents were treated by radiotherapy. Above all the connective and supporting tissue seems involved. Some proposals are made how to give a radiogenetic advice to tumor patients who want to have children. (orig.)

    Five or ten years after a first examination, 55 children were submitted to a check-up investigation of their physical and intellectual development. The group of twenty irradiated fathers received an average dose to the gonads of 0.55 Gy (0.01 to 6.4 Gy), the group of twenty irradiated mothers 0.72 Gy (0.01 to 8.0 Gy). In all parents the most frequent finding was Hodgkin's disease, which was diagnosed as a neoplams in 23 cases. The proof of paternity was made with a 86% accuracy for ten out of twenty fathers by determination of HLA types. A conception was demonstrated beyond all doubt after a dose to the testicles of 1.2 Gy in the irradiated fathers and after a dose to the ovaries of 3.0 Gy in the irradiated mothers. The offspring of the F/sub 1/ generation showed no modification in the sex ratio. A rate of 5.5% of severe malformations was found (trisomy E, bradyacousia of the inner ear, cleft hands and feet). 24% of the children had malformations which needed a treatment (hernias, torticollis, hip dysplasia). 18 out of 55 children (33%) presented abnormalities in the widest sense of the word. Three children (5.5%) were premature infants, and there is a general tendency towards shortened pregnancy (-3.6 days). Hernias (7/55) are a frequent finding. In children of both sexes, carporadiography shows a delayed development which is not compensated in the check-up examinations at five or ten years, but does not cause an underdevelopment in body height as compared to great normal collectives. The results suggest a slightly increased malformation rate among children whose parents were treated by radiotherapy. Above all the connective and supporting tissue seems involved. Some proposals are made how to give a radiogenetic advice to tumor patients who want to have children.

  17. Physicochemical characterisation of fluids and soft foods frequently mixed with oral drug formulations prior to administration to children.

    2016-03-01

    Oral drug administration to children poses specific pharmaceutical challenges that are often not seen to the same extent in adults, and whose occurrence may also be age dependent. When an age-appropriate dosage form is not available, manipulation of adult dosage forms (e.g., splitting and crushing of tablets or opening of capsules) has been reported as a means to facilitate administration to children. To enhance swallowability and/or mask an unpleasant taste of the dosage form to be administered, crushed/split tablets or the contents of capsules are often mixed with food or drinks or suspended in a vehicle prior to administration. However, it seems that the risks and benefits of an approach whereby the dosage form is modified prior to administration in this manner are everything but clear. The aim of the present study was to gain an overview of the physicochemical properties of a number of fluids, soft foods and suspension vehicles that are commonly reported to be mixed with oral medications before administration to children to improve patient acceptability. For this purpose, physicochemical parameters of 15 different fluids, soft foods and suspension vehicles were measured. These included pH, buffer capacity, osmolality, surface tension and viscosity. Results of the study clearly show the differences in physicochemical properties of the test candidates. It is thus obvious that the type of fluid/food mixed with a drug product before administration may have a significant impact on bioavailability of the drug administered. Therefore, a risk-based assessment of such practices considering API properties, formulation features and physicochemical properties of the fluids and foods intended to be co-administered with the dosage form, in conjunction with the anatomical and physiological maturity of the gastro-intestinal tract in the intended paediatric population, should be an essential part of paediatric oral formulation development.

    Pre-existing immunity played a significant role in protection during the latest influenza A virus H1N1 pandemic, especially in older age groups. Structural similarities were found between A(H1N1)2009 and older H1N1 virus strains to which humans had already been exposed. Broadly cross-reactive antibodies capable of neutralizing the A(H1N1)2009 virus have been implicated in this immune protection in adults. We investigated the serological profile of a group of young children aged 9 years (n=55), from whom paired blood samples were available, just prior to the pandemic wave (March 2009) and shortly thereafter (March 2010). On the basis of A(H1N1)2009 seroconversion, 27 of the 55 children (49 %) were confirmed to be infected between these two time points. Within the non-infected group of 28 children (51 %), high levels of seasonal antibodies to H1 and H3 HA1 antigens were detected prior to pandemic exposure, reflecting past infection with H1N1 and H3N2, both of which had circulated in The Netherlands prior to the pandemic. In some children, this reactivity coincided with specific antibody reactivity against A(H1N1)2009. While these antibodies were not able to neutralize the A(H1N1)2009 virus, they were able to mediate antibody-dependent cellular cytotoxicity (ADCC) in vitro upon interaction with the A(H1N1)2009 virus. This finding suggests that cross-reactive antibodies could contribute to immune protection in children via ADCC.

    Guanfacine extended release (GXR) and atomoxetine (ATX) are nonstimulant treatments for attention-deficit/hyperactivity disorder (ADHD). As nonstimulant treatments are often used after stimulants in ADHD, GXR was assessed relative to prior stimulant treatment in a randomized controlled trial (RCT), in which ATX was included as a reference arm, and in the open-label phase of a randomized-withdrawal study (RWS). Participants were 6–17 years old with ADHD Rating Scale version IV (ADHD-RS-IV) scores ≥32 and Clinical Global Impressions – Severity scores ≥4. RCT participants received dose-optimized GXR (1–7 mg/day), ATX (10–100 mg/day), or placebo for 10–13 weeks. RWS participants received dose-optimized GXR (1–7 mg/day) for 13 weeks. Participants’ last stimulant medication prior to enrolment, and reasons for stopping this medication, were collected at baseline. Change from baseline ADHD-RS-IV score and the proportion of responders were assessed by prior stimulant exposure. Of 163 RCT and 296 RWS participants who had previously received stimulant treatment, 142 and 224, respectively, had received methylphenidate (MPH); due to the low number of participants and the heterogeneity of non-MPH treatments, we only report data for prior MPH treatment. The most frequent reasons for stopping MPH were lack of effectiveness or side effects. Placebo-adjusted ADHD-RS-IV changes from baseline were significant in participants receiving GXR (prior MPH, −9.8, P0.05, ES 0.15) participants. More participants met responder criteria with GXR versus placebo, regardless of prior treatment. GXR response was unaffected by prior stimulant treatment; ATX produced improvement only in stimulant-naïve participants relative to placebo. These findings may be relevant to clinical decision-making regarding sequencing of ADHD treatments. PMID:27226715

    Children with life limiting conditions and their families have complex needs. Evaluations must consider their views and perspectives to ensure care is relevant, appropriate and acceptable. We consulted with children, young people, their parents and local professionals to gain a more informed picture of issues affecting them prior to preparing a bid to evaluate services in the area. Multiple methods included focus groups, face-to-face and telephone interviews and participatory activities. Recordings and products from activities were analysed for content to identify areas of relevance and concern. An overarching theme from parents was 'Why does it happen like this?' Services did not seem designed to meet their needs. Whilst children and young people expressed ideas related to quality of environment, services and social life, professionals focused on ways of meeting the families' needs. The theme that linked families' concerns with those of professionals was 'assessing individual needs'. Two questions to be addressed by the evaluation are (1) to what extent are services designed to meet the needs of children and families and (2) to what extent are children, young people and their families consulted about what they need? Consultations with families and service providers encouraged us to continue their involvement as partners in the evaluation. PMID:24270996

    Persson, Hanna; Nasta, Federico; Svensson, Ingrid; Widerström, Micael

    Hepatitis A (HAV) is a low incidence infectious disease in Sweden, and a majority of cases in this country are acquired abroad, although domestic cases are not uncommon in the day care setting. We investigated an outbreak of hepatitis A in two day care centres and found that a large proportion (23%) of the 113 unvaccinated preschool children were immune to HAV. This observation indicates that there may have been sub-clinical cases of HAV at the two centres. The results of our study underscore the importance of HAV vaccination in preschool children prior to travel to areas where this disease is common. The findings also highlight the need for up-to-date national seroepidemiological data on HAV immunity in different age groups in Sweden. Studies aimed at obtaining such information could also provide a basis for deciding whether targeted vaccination strategies against HAV are needed in the day care setting. PMID:25462320

  16. Maternal influences on early development: preferred temperature prior to oviposition hastens embryogenesis and enhances offspring traits in the Children's python, Antaresia childreni.

    Embryonic life is particularly sensitive to its surroundings, and the developmental environment can have long-lasting effects on offspring. In oviparous species, the impacts of the developmental environment on offspring traits are mostly examined during development within the egg. However, as more than 25% of the development of squamate reptiles can occur prior to oviposition, we explored the effect of thermal conditions on development prior to oviposition in an oviparous snake species, the Children's python (Antaresia childreni). We housed gravid female pythons under three thermal cycles: an optimal regime that reflected maternal preference in a non-constrained environment (constant preferred body temperature of gravid females, T(set)=31.5°C) and two mildly suboptimal regimes that shared the same mean temperature of 27.7°C, but differed in the duration at T(set). In one of the constraining regimes, females had access to T(set) for 4 h daily whereas in the other regime, females never reached T(set) (maximal temperature of 29.0°C). Thermal treatments were maintained throughout gravidity in all three groups, but, after oviposition, all eggs were incubated at T(set) until hatching. Compared with the optimal regime, the two suboptimal regimes had a longer duration of gravidity, which resulted in delayed hatching. Between the two suboptimal regimes, gravidity was significantly shorter in the treatment that included time at T(set). Furthermore, suboptimal regimes influenced offspring traits at hatching, including body morphology, antipredator behavior, strength and metabolism. However, partial access to maternal T(set) significantly enhanced several offspring traits, including performance. Our results demonstrate the importance of time at T(set) on early development and suggest an adaptive significance of maternal thermoregulation prior to oviposition.

The complexed analyte was quantitatively extracted with octylphenoxypolyethoxyethanol (Triton X-114). The multivariate strategy was applied to estimate the optimum values of experimental factors. Acidic ethanol was added to the surfactant-rich phase prior to its analysis by flame atomic absorption spectrometer (FAAS). The detection limit value of Pb{sup 2+} for the preconcentration of 10 mL of acid digested blood sample was 1.14 {mu}g L{sup -1}. The accuracy of the proposed methods was assessed by analyzing certified reference material (whole blood). Under the optimized conditions of both CPE methods, 10 mL of Pb{sup 2+} standards (10 {mu}g L{sup -1}) complexed with APDC and DDTC, permitted the enhancement factors of 56 and 42, respectively. The proposed method was used for determination of Pb{sup 2+} in blood samples of children with kidney disorders and healthy controls.

    2012-06-01

    Full Text Available Abstract Background The birth of a child with a cleft lip, whether or not in association with a cleft palate, is a traumatic event for parents. This prospective, multidisciplinary and multi-centre study aims to explore the perceptions and feelings of parents in the year following the birth of their child, and to analyse parent–child relationships. Four inclusion centres have been selected, differing as to the date of the first surgical intervention, between birth and six months. The aim is to compare results, also distinguishing the subgroups of parents who were given the diagnosis in utero and those who were not. Methods/Design The main hypothesis is that the longer the time-lapse before the first surgical intervention, the more likely are the psychological perceptions of the parents to affect the harmonious development of their child. Parents and children are seen twice, when the child is 4 months (T0 and when the child is one year old (T1. At these two times, the psychological state of the child and his/her relational abilities are assessed by a specially trained professional, and self-administered questionnaires measuring factors liable to affect child–parent relationships are issued to the parents. The Alarme Détresse BéBé score for the child and the Parenting Stress Index score for the parents, measured when the child reaches one year, will be used as the main criteria to compare children with early surgery to children with late surgery, and those where the diagnosis was obtained prior to birth with those receiving it at birth. Discussion The mental and psychological dimensions relating to the abnormality and its correction will be analysed for the parents (the importance of prenatal diagnosis, relational development with the child, self-image, quality of life and also, for the first time, for the child (distress, withdrawal. In an ethical perspective, the different time lapses until surgery in the different protocols and their

    2010-01-01

    Parenting is related to children's adjustment, but little research has examined the role of parenting in children's responses to disasters. This study describes parenting responses specific to the 9/11 terrorist attacks and examines pre-9/11 parenting, child temperament, and 9/11-specific parenting as predictors of children's posttraumatic stress (PTS) symptoms among children geographically distant from the attack locations. A community sample of children and parents (n = 137, ages 9-13 years) participating in an ongoing study were interviewed 1 month following 9/11. Parents reported engaging in a number of parenting responses following 9/11. Pre-9/11 acceptance and 9/11-specific, self-focused parental responses predicted PTS symptoms. Pre-9/11 parenting and temperament interacted to predict PTS symptoms, suggesting that parenting and temperament are important prospective predictors of children's responses to indirect exposure to disasters.

    1987-01-01

    The abuse of children is presumed by most mental health professionals to occur at the hands of parents who were themselves harshly traumatized by abuse or neglect. A 14-month-old child is presented who was well treated by his family and developed well until 6.5 months of age, after which, due to traumatization of his mother, the child became neglected and physically abused. In a therapeutic-observational environment, as the child recovered from his massive depression, much explosive destructive behavior not seen in him before was observed. From his past studies and those of other psychoanalysts, the author presents the collectively advanced hypothesis that excessive unpleasure mobilizes hostility in humans and suggests that this hypothesis may be fruitfully applied to explain why the abused become abusers. The hypothesis may also serve to guide the treatment of abused children so as to prevent their becoming tomorrow's abusers. Furthermore, the hypothesis suggests that strategies can be proposed toward preventing child abuse. PMID:3676889

    Having just emerged from the warmest decade on record and watching as the oceans acidify and sea level rises, global resources peak, the world's population continues to climb, and nearly half of all known species face extinction by the end of the century. We stand on the threshold of one of the most important transition in human history-the transition from hunting-and-gathering our energy to cultivating sustainable, carbon-neutral, environmentally-friendly energy supplies. Can we develop an alternative to fossil fuels in time to make a difference for our children and the "children" of all species? NASA puts people into outer space, where all resources (food, water, air, pressure, gravity, energy) are limited and far away and where conditions (temperature, radiation, vacuum) are problematic and dangerous-the life expectancy of an unprotected astronaut (physically exposed to the space environment) is 15 seconds. Therefore, by necessity, NASA has explored and developed "life-support systems" that optimize the use of resources, minimize the use of energy, and recycle, refurbish, re-use everything that on earth would be considered a waste material. Emerging from the legacy of life-support systems, the NASA OMEGA project uses microalgae, municipal wastewater, and the encroaching oceans to address our global needs for a sustainable, carbon-neutral, environmentally friendly energy supply that does not compete with agriculture. The OMEGA project is focused on producing aviation fuel, treating municipal wastewater, and sequestering carbon dioxide. More generally, however, OMEGA is an example of an "ecology of technologies" in which all processes are integrated and inter-dependent and wastes become resources. From a NASA perspective, the OMEGA project is also a reminder that "we are not passengers on Spaceship Earth, we are the crew."

  8. Accelerated evolution of the ASPM gene controlling brain size begins prior to human brain expansion.

    Directory of Open Access Journals (Sweden)

    Natalay Kouprina

    2004-05-01

    Full Text Available Primary microcephaly (MCPH is a neurodevelopmental disorder characterized by global reduction in cerebral cortical volume. The microcephalic brain has a volume comparable to that of early hominids, raising the possibility that some MCPH genes may have been evolutionary targets in the expansion of the cerebral cortex in mammals and especially primates. Mutations in ASPM, which encodes the human homologue of a fly protein essential for spindle function, are the most common known cause of MCPH. Here we have isolated large genomic clones containing the complete ASPM gene, including promoter regions and introns, from chimpanzee, gorilla, orangutan, and rhesus macaque by transformation-associated recombination cloning in yeast. We have sequenced these clones and show that whereas much of the sequence of ASPM is substantially conserved among primates, specific segments are subject to high Ka/Ks ratios (nonsynonymous/synonymous DNA changes consistent with strong positive selection for evolutionary change. The ASPM gene sequence shows accelerated evolution in the African hominoid clade, and this precedes hominid brain expansion by several million years. Gorilla and human lineages show particularly accelerated evolution in the IQ domain of ASPM. Moreover, ASPM regions under positive selection in primates are also the most highly diverged regions between primates and nonprimate mammals. We report the first direct application of TAR cloning technology to the study of human evolution. Our data suggest that evolutionary selection of specific segments of the ASPM sequence strongly relates to differences in cerebral cortical size.

    Parents and caregivers often try various treatment modalities for their sick children before bringing them to clinic. Many community-based studies have documented home and self-treatment practices, often with the aid of patent medicine vendors, but less is known about prior treatment behaviour of caregivers who actually reach a government clinic. This study, therefore, aimed at documenting the treatment provided by caregivers prior to their attendance at a public hospital. Beginning in April 1996, a year-long study was conducted among 1,943 sick children and their caregivers who attended the largest government-owned paediatric hospital in Lagos, Nigeria. The major complaints mentioned by the caregivers included fever, cough, and diarrhoea. Most (89%) caregivers had administered some form of medicine to the child prior to the clinic visit, and on average, 2.5 medications had been given. Associations were found between major complaint and type of medicine given: fevers were associated with antimalarial drugs and analgesics (antipyretics), cough was associated with cough syrup and analgesics, while diarrhoea was associated with antidiarrhoeal drugs. Although one-fifth of the children had received an antibiotic, provision of antibiotics was not associated with a particular complaint/illness. Since caregivers appeared to use perceived complaints/illnesses as a treatment guide, this can form the basis of safer and more appropriate recognition of illness and home management. In addition, the information obtained in this study can be used for training clinicians to inquire about home management and, thus, for making more informed decisions about their own treatment and prescribing practices.

    Chemical analyses of ancient organic compounds absorbed into the pottery fabrics of imported Etruscan amphoras (ca. 500-475 B.C.) and into a limestone pressing platform (ca. 425-400 B.C.) at the ancient coastal port site of Lattara in southern France provide the earliest biomolecular archaeological evidence for grape wine and viniculture from this country, which is crucial to the later history of wine in Europe and the rest of the world. The data support the hypothesis that export of wine by ship from Etruria in central Italy to southern Mediterranean France fueled an ever-growing market and interest in wine there, which, in turn, as evidenced by the winepress, led to transplantation of the Eurasian grapevine and the beginning of a Celtic industry in France. Herbal and pine resin additives to the Etruscan wine point to the medicinal role of wine in antiquity, as well as a means of preserving it during marine transport.

    The emerging reading and spelling abilities of 24 deaf and 23 hearing beginning readers were followed over 2 years. The deaf children varied in their language backgrounds and preferred mode of communication. All children were given a range of literacy, cognitive and language-based tasks every 12 months. Deaf and hearing children made similar progress in literacy in the beginning stages of reading development and then their trajectories began to diverge. The longitudinal correlates of beginning reading in the deaf children were earlier vocabulary, letter-sound knowledge, and speechreading. Earlier phonological awareness was not a longitudinal correlate of reading ability once earlier reading levels were controlled. Only letter name knowledge was longitudinally related to spelling ability. Speechreading was also a strong longitudinal correlate of reading and spelling in the hearing children. The findings suggested that deaf and hearing children utilize slightly different reading strategies over the first 2 years of schooling.

    This study reports two experiments assessing the spelling performance of French first graders after 3 months and after 9 months of literacy instruction. The participants were asked to spell high and low frequency irregular words (Experiment 1) and pseudowords, some of which had lexical neighbours (Experiment 2). The lexical database which children had been exposed to was strictly controlled. Both a frequency effect in word spelling accuracy and an analogy effect in pseudoword spelling were obtained after only 3 months of reading instruction. The results suggest that children establish specific orthographic knowledge from the very beginning of literacy acquisition. PMID:14738774

  8. When Did Plate Tectonics Begin

    Science.gov (United States)

    Brown, M.

    2015-12-01

    Present-day plate tectonics on Earth is characterized by asymmetric (one-sided) subduction, but how do we recognize the imprint of subduction in the geologic record? How do we weigh global (commonly younger) vs local (commonly older) datasets or distinguish initiation from episodic from continuous subduction? How reliable are data gaps? Characteristics of the Paleozoic record of subduction include calc-alkaline magmatism, blueschist/UHP metamorphism and collisional orogenesis, and ophiolites as representatives of former ocean lithosphere. Are these characteristic rocks preserved in Proterozoic, Archean and Hadean crust? Does a hotter mantle, higher heat production and weaker lithosphere modify or eliminate these features? What preceded subduction and how do we recognize that regime? Are rock associations or geochemical fingerprints reliable? Does reworking and overprinting modify geochemical fingerprints? Proposals for the start of plate tectonics have been based on: persistence of isotope anomalies/fractionated chemical domains in the mantle; changes in chemistry of magmatic rocks, rates of crustal growth vs reworking, and sites of growth; the metamorphic record, particularly the first appearance of contrasting thermal gradients or eclogite (including evidence from mineral inclusions in diamonds) or UHP metamorphic rocks; stabilization of cratonic lithosphere and formation of supercratons, and the beginning of the Proterozoic supercontinent cycle; the end of the flat Earth, emergence of continents, development of significant topography, changes in the style of orogeny and the rise in atmospheric oxygen; and, the appearance of passive margins and changes in the style of sedimentation. Estimates of the timing have varied from the Hadean to Neoproterozoic. I will summarize evidence for a growing consensus that the late Mesoarchean to early Paleoproterozoic was a 700 Myr long period of transition to continuous (?) subduction and global (?) mobile-lid plate tectonics.

    Following the transfusion of a young woman with two units of blood infected by human immunodeficiency virus (HIV) during a Cesarean section performed at the Obstetrics and Gynecology Unit of Port-Royal Hospital in Paris in 1984, the author realized the danger that this virus would represent for women and their children, at a time when the infection seemed to be confined to homosexuals, drug addicts, hemophiliacs and transfusion recipients. He was confronted with a whole series of issues, including the rejection of HIV-positive women; the need for special precautions in the labor room and operating theater; and the need for these patients to be managed in a single center staffed by skilled and willing healthcare professionals who could help them decide whether or not to continue the pregnancy. The main risks at this time were the onset of life-threatening opportunistic infections during pregnancy and HIV transmission to the child (estimated at 20% to 30%). Other thorny issues included the case of couples wishing to have children when either of the two members was infected, and the question of professional confidentiality when an immunocompromised HIV-seropositive husband stubbornly refused to inform his wife or to use condoms. It seemed important to bring these women together, especially those of African origin, within a self-help group where they could express themselves openly and discuss their difficulties. Screening for HIV antibodies in early pregnancy became necessary to permit preventive treatment of mother-child HIV transmission, and to inform pediatricians. There was also a need to estimate and monitor the seroprevalence of HIV among pregnant women, and this was done by conducting a "sentinel" survey that was subsequently taken over by INSERM and the European Centre for the Epidemiological Monitoring of AIDS. After listing many other issues that were hotly debated over the years, the author describes how, at the beginning of the epidemic, new proposals

  17. How did the Universe Begin?

    Science.gov (United States)

    Pollock, M. D.

    The question of the initial configuration of the Universe — did the expanding Friedmann space-time ds2 = dt2 - a2(t)dx2 tend to a singularity when extrapolated back in time, or was there a turning point, indicating a previous phase of contraction? — is re-examined in the context of the heterotic superstring theory of Gross et al. If the adiabatic index tends to the value γ = 1, then the higher-derivative terms ℛ2 in the Lagrangian L dominate the Einstein-Hilbert term R/16πG in the time interval tp ≲ t ≲ 4tp, during which the action is S ≈ 25ℏ, guaranteeing the approximate validity of the classical field equations (if the compactification process is ignored), where G≡ t2p is the Newton gravitational constant and tp is the Planck time. Under these conditions, Ruzmaĭkina and Ruzmaĭkina have shown, for a flat three-space with K = 0, that the initial singularity can only be avoided at all if there is a spin-zero tachyon, a conclusion modified by Barrow and Ottewill if K = ±1. We have previously shown, however, that the theory is tachyon-free, and have argued that K has to vanish for the existence of a well-defined, quantum-mechanical ground state. Also, if there is no inflation, the radius function is always much too large for the terms in K to exert any effect, a(t) ≳ 5 × 1029tp. While if γ = 2, then ℛ2 never dominates R/16πG. Accordingly, we conjecture that the Universe did not bounce, irrespective of the value of γ, the absence of a prior contracting phase thus being an aspect of causality.

    When, in the course of advancing the state of the art, one slams into a material barrier to the construction of one's appointed gadget, it is customary, and at times mandatory, to drop to one's knees and pray to DARPA for deliverance. Deliverance in the form of the right stuff. Something superbly strong, something utterly transparent, something remarkably light, and with dielectric properties rivaling a perfect vacuum. Ideally, this something should also be bulletproof, better at conducting heat than a silver spoon, insoluble in boiling acid, radiation hard, non-toxic, and cheap. Well, historically, nine out of ten isn't bad for a start. Indeed, it's better than nothing. So let me begin with some history. What we today call solid state physics began not as science but as technology. Victorian low technology to be exact. The first practical solid state electronic devices, demonstrated by Ferdinand Braun* at Leipzig on November 14, 1876, were based neither on theory nor on synthesis, nor on crystal growth. For in those days these things existed not. They were instead dug up, mined as lead ore. The performance of the galena (PbS) cat's whisker diode was marginal; it was rapidly superseded by the first, worse vacuum tube . So also, early infrared optics of rock salt gave way to synthetic crystals. But those early artifacts' performance demanded a physical explanation, and after a brief hiatus, in order for Willard Gibbs to break ground by inventing thermodynamics, the modern theory of solids arose to provide it. It all stemmed from the enterprise of explaining first the optical properties and then the electronic bebavior of crystals found in rocks. Today diamond, along perhaps with Iceland spar, remains the last optical material to be technically exploited as it is found in nature. It is a barbarous relic, a throwback to high technology's dim Neolithic past. For nowadays we are used to thinking about synthetic optical materials, like zinc sulfide or selenide, as being

    Rapid growth of nuclear physics in fifties attracted attention of numerous scientists, mainly physicists. At the same time, governments become interested in the field, expecting various advantages, and to be honest, in the first place the nuclear weapons. As a result, also in the country at that time called Yugoslavia, the Federal Nuclear Agency has been formed, and generously funds have been given to support the research. In Yugoslavia three nuclear centers have been founded: in Belgrade (Serbia), Zagreb (Croatia) and Ljubljana (Slovenia). The nuclear research and applications to related fields, inevitably was related to the physics of ionized gases. Just to mention electro-magnetic separation of isotopes, mass spectrometry, gas filled nuclear radiation detectors, accelerator ion sources, sources for analytical spectroscopy and others. Right from the beginning a common problem has been met: lack of basic knowledge on elementary collision processes and in general on the matter in ionized state. Groups of physicists in the mentioned institutes have started paying full attention to these problems. They found it of interest to exchange the results and cooperate not only between themselves but also with research centers in other countries. It was felt that at least one national meeting should be organized, where an overview of activities in the field of ionized gases could be presented. Thanks to extraordinary efforts of prof. B. Perovic, supported, backed and simulated by prof. A. Milojevic, prof. Z. Sternberg, prof. Dj. Bosan and prof. A. Moljk first such meeting was prepared. In 1962 the "Ist Yugoslav Symposium an the Physics of Ionized Gases" was organized in Belgrade. Six invited lectures and 26 original contributions were presented. Two years later, in 1964, the second meeting of the same title was held in Zagreb (Croatia). The large number of participants and unexpected interest in field has initiated an idea that the study of different fields related to the

  3. Bayesian priors for transiting planets

    CERN Document Server

    Kipping, David M

    2016-01-01

    As astronomers push towards discovering ever-smaller transiting planets, it is increasingly common to deal with low signal-to-noise ratio (SNR) events, where the choice of priors plays an influential role in Bayesian inference. In the analysis of exoplanet data, the selection of priors is often treated as a nuisance, with observers typically defaulting to uninformative distributions. Such treatments miss a key strength of the Bayesian framework, especially in the low SNR regime, where even weak a priori information is valuable. When estimating the parameters of a low-SNR transit, two key pieces of information are known: (i) the planet has the correct geometric alignment to transit and (ii) the transit event exhibits sufficient signal-to-noise to have been detected. These represent two forms of observational bias. Accordingly, when fitting transits, the model parameter priors should not follow the intrinsic distributions of said terms, but rather those of both the intrinsic distributions and the observational ...

  4. Mixtures of Gaussian process priors

    CERN Document Server

    Lemm, J C

    1999-01-01

    Nonparametric Bayesian approaches based on Gaussian processes have recently become popular in the empirical learning community. They encompass many classical methods of statistics, like Radial Basis Functions or various splines, and are technically convenient because Gaussian integrals can be calculated analytically. Restricting to Gaussian processes, however, forbids for example the implemention of genuine nonconcave priors. Mixtures of Gaussian process priors, on the other hand, allow the flexible implementation of complex and situation specific, also nonconcave "a priori" information. This is essential for tasks with, compared to their complexity, a small number of available training data. The paper concentrates on the formalism for Gaussian regression problems where prior mixture models provide a generalisation of classical quadratic, typically smoothness related, regularisation approaches being more flexible without having a much larger computational complexity.

    Though Arthur Prior is now best known for his founding of modern temporal logic and hybrid logic, much of his early philosophical career was devoted to history of logic and historical logic. This interest laid the foundations for both of his ground-breaking innovations in the 1950s and 1960s. Becaus

  13. Quantum steganography using prior entanglement

    Energy Technology Data Exchange (ETDEWEB)

    Mihara, Takashi, E-mail: mihara@toyo.jp

    2015-06-05

    Steganography is the hiding of secret information within innocent-looking information (e.g., text, audio, image, video, etc.). A quantum version of steganography is a method based on quantum physics. In this paper, we propose quantum steganography by combining quantum error-correcting codes with prior entanglement. In many steganographic techniques, embedding secret messages in error-correcting codes may cause damage to them if the embedded part is corrupted. However, our proposed steganography can separately create secret messages and the content of cover messages. The intrinsic form of the cover message does not have to be modified for embedding secret messages. - Highlights: • Our steganography combines quantum error-correcting codes with prior entanglement. • Our steganography can separately create secret messages and the content of cover messages. • Errors in cover messages do not have affect the recovery of secret messages. • We embed a secret message in the Steane code as an example of our steganography.

  19. Aquinas and Contemporary Cosmology: Creation and Beginnings

    Science.gov (United States)

    Carroll, William E.

    Discussions in the Middle Ages about creation and the temporal beginning of the world involved sophisticated analyses in theology, metaphysics, and natural philosophy. Mediaeval insights on this subject, especially Thomas Aquinas' defense of the intelligibility of an eternal, created universe, can help to clarify reflections about the philosophical and theological implications of contemporary cosmological theories: from the "singularity" of the Big Bang, to "quantum tunneling from nothing," to multiverse scenarios. Thomas' insights help us to see the value of Georges Lemaître's insistence that his cosmological reflections must be kept separate from an analysis of creation. This essay will look at different senses of "beginning" and examine the claim that creation, in its fundamental meaning, tells us nothing about whether there is a temporal beginning to the universe. Multiverse models, like that recently proposed by Stephen Hawking and Leonard Mlodinow, may challenge certain views of a Grand Designer, but not of a Creator.

    Full Text Available Background: Since mankind’s onset, breast milk has been the main source of food for little children. Nevertheless, in recent years there has been an alarming trend to the decline of this practice. Objective: To determine the behaviour of exclusive breastfeeding in children of mothers with and without previous training. Methods: A community intervention, quasi-experimental, comparative and prospective study was conducted. The sample, including 160 women who had given birth in 2005 and 2006 and belonged to the Area III Polyclinic of Cienfuegos, was divided into two independent groups: one trained in breastfeeding and the other one not trained. The variables included were: age, occupation, educational level, duration of exclusive and mixed breastfeeding and introduction of artificial and complementary feeding. Results: younger mothers (42, 5% and those who were still students are in the untrained group. The elimination of exclusive breastfeeding and the replacement of mixed feeding by artificial feeding are more precocious in the untrained mothers group (43, 8% nursed less than 2 months. The introduction of complementary breastfeeding was lower in the group of untrained mothers (23, 8% did so in 4 to 5 months. Conclusions: Training provided before or immediately after delivery is an extremely useful tool to improve quantitatively and qualitatively breastfeeding.Fundamento: desde que existe la humanidad la leche materna ha constituido la fuente principal de alimento para el niño pequeño.

  4. A Geometric View of Conjugate Priors

    CERN Document Server

    Agarwal, Arvind

    2010-01-01

    In Bayesian machine learning, conjugate priors are popular, mostly due to mathematical convenience. In this paper, we show that there are deeper reasons for choosing a conjugate prior. Specifically, we formulate the conjugate prior in the form of Bregman divergence and show that it is the inherent geometry of conjugate priors that makes them appropriate and intuitive. This geometric interpretation allows one to view the hyperparameters of conjugate priors as the {\\it effective} sample points, thus providing additional intuition. We use this geometric understanding of conjugate priors to derive the hyperparameters and expression of the prior used to couple the generative and discriminative components of a hybrid model for semi-supervised learning.

  7. On New Beginnings and Democratic Legitimacy

    Directory of Open Access Journals (Sweden)

    Signe Larsen

    2013-06-01

    Full Text Available This paper sets out to discuss the enigma of revolutionary new political beginnings of constitutional orders. The problem is that when a political community is constituted, the act of constituting per definition is unconstitutional or extra-legal. For this reason the question of new beginnings is a political and not a legal question. The question of what the authority of the constituent act is presents an important question since the constitution is the fundamental law from which the legitimacy or authority of all other laws is derived. The problem for this paper is whether and in what way it is possible to think new beginnings that are not merely institutionalizations of factual relations of domination or arbitrary acts of violence. This problem is discussed on basis of two revolutionary theories in the tradition of constituent power—Emmanuel Sieyès and Hannah Arendt—that both understand power to emanate from below and not from above whereby they both, though in different way, present arguments against the understanding that new beginnings merely are institutionalizations of relations of domination and arbitrary acts of violence. The question of whether and to what extent they are successful and whether their theories are democratic will finally be discussed.

    2014-12-01

    Full Text Available This study investigates the relationship between prior knowledge and reading comprehension in second language among postgraduate students in UPM. Participants in the study were 20 students who have the same level in English as a second language from several faculties. On the basis of a prior-knowledge questionnaire and test, students were selected; they were asked to sit a two-passage reading comprehension exam. According to the questionnaire and the short prior quiz, students had high prior knowledge in one of the two passages, and low prior knowledge in the other. The result showed significantly high relationship between the high prior knowledge and reading comprehension. However, the results showed significantly low relationship between low prior knowledge and reading comprehension. Yet the performance of students in a reading comprehension with high prior knowledge was significantly better than reading comprehension with low prior knowledge.

    The first galaxies in the universe are the building blocks of all observed galaxies. We present scaling relations for galaxies forming at redshifts z ≥ 15 when reionization is just beginning. We utilize the 'Rarepeak' cosmological radiation hydrodynamics simulation that captures the complete star formation history in over 3300 galaxies, starting with massive Population III stars that form in dark matter halos as small as ∼10{sup 6} M {sub ☉}. We make various correlations between the bulk halo quantities, such as virial, gas, and stellar masses and metallicities and their respective accretion rates, quantifying a variety of properties of the first galaxies up to halo masses of 10{sup 9} M {sub ☉}. Galaxy formation is not solely relegated to atomic cooling halos with virial temperatures greater than 10{sup 4} K, where we find a dichotomy in galaxy properties between halos above and below this critical mass scale. Halos below the atomic cooling limit have a stellar mass-halo mass relationship log M {sub *} ≅ 3.5 + 1.3log (M {sub vir}/10{sup 7} M {sub ☉}). We find a non-monotonic relationship between metallicity and halo mass for the smallest galaxies. Their initial star formation events enrich the interstellar medium and subsequent star formation to a median of 10{sup –2} Z {sub ☉} and 10{sup –1.5} Z {sub ☉}, respectively, in halos of total mass 10{sup 7} M {sub ☉}, which is then diluted by metal-poor inflows well beyond Population III pre-enrichment levels of 10{sup –3.5} Z {sub ☉}. The scaling relations presented here can be employed in models of reionization, galaxy formation, and chemical evolution in order to consider these galaxies forming prior to reionization.

  2. Qualitative alteration of peripheral motor system begins prior to appearance of typical sarcopenia syndrome in middle-aged rats

    Directory of Open Access Journals (Sweden)

    Tetsuro eTamaki

    2014-10-01

    Full Text Available Qualitative changes in the peripheral motor system were examined using Young, Adult, Middle-aged and Old-aged rats in order to assess before and after the appearance of sarcopenia symptoms. Significant loss of muscle mass and strength, and slow-type fiber grouping with a loss of innervated nerve fibers were used as typical markers of sarcopenia. Dynamic twitch and tetanus tension and evoked electromyogram (EEMG were measured via electrical stimulation through the sciatic nerve under anesthesia using our force-distance transducer system before and after sciatectomy. Digital and analogue data sampling was performed and shortening and relaxing velocity of serial twitches was calculated with tension force. Muscle tenderness in passive stretching was also measured as stretch absorption ability, associated with histological quantitation of muscle connective tissues. The results indicated the validity of the present model, in which Old-aged rats clearly showed the typical signs of sarcopenia, specifically in the fast-type plantaris muscles, while the slow-type soleus showed relatively mild syndromes. These observations suggest the following qualitative alterations as the pathophysiological mechanism of sarcopenia: 1 reduction of shortening and relaxing velocity of twitch; 2 decline of muscle tenderness following an increase in the connective tissue component; 3 impaired recruitment of motor units (sudden depression of tetanic force and EEMG in higher stimulation frequencies over 50-60 Hz; and 4 easy fatigability in the neuromuscular junctions. These findings are likely to be closely related to significant losses in fast-type motor units, muscle strength and contraction velocity, which could be a causative factor in falls in the elderly. Importantly, some of these symptoms began in Middle-aged rats that showed no other signs of sarcopenia. Thus, prevention should be started in middle age that could be retained relatively higher movement ability.

  3. From the beginning of radon therapy

    International Nuclear Information System (INIS)

    The revival of the radon therapy in several countries since the end of the Second World War was the occasion for a review to the beginnings of this special form of radiotherapy. Initially the early history of radioactivity research is described which among others led to the detection of the emanation as a daughter product of radium. After this followed the evidence of the emanation as a constituent of the natural atmosphere. The establishment of its presence in spring-waters led to the knowledge that there are more than average concentrations of emanation in several mineral springs. In the second part of the article the therapeutic use of the natural radon springs initiated by this is described in its development and importance for Austria (Badgastein, St. Joachimsthal) and Germany (Bad Brambach) up to the beginning of the First World War.

  6. [When does human life begin? Legal considerations].

    Science.gov (United States)

    Koch, H G

    1993-11-01

    There have been attempts to define the beginning of life from a legal point of view. The German civil code of 1923 specified that only that entity can have birthright that was alive at the time of succession. Whoever was not alive at the time of succession but was already fertilized would be deemed as born before the succession. The law in this instance does not really define life, rather it regulates the hereditary right of the fetus. Less subject to misunderstanding is Paragraph 1 of the German Law Book, which refers to the legal rights of human beings from the completion of birth, specifying only the live born and not the still-born. The embryo protection law in force as of January 1, 1991, defines the beginning of life in a medical sense, to wit, the embryo is the fertilized egg cell capable of development already from the time of fertilization. Additionally every cell with the potential to divide and develop into an individual is assumed as an embryo. No other law explicitly provides a similar definition of the appearance of early human life. Some foreign legal precepts designate the embryonic conceptus the preembryo, which could be subjected to procedures in reproductive medicine to which more developed embryos could not be. According to the valid Paragraph 219 d of the Penal Code, a procedure is not considered an abortion when its effects occur before the completion of nidation of the fertilized egg cell in the uterus. This does not define the beginning of life, it only says something about the beginning of legal protection of unborn life. In the view of constitutional law Article 2, Section 2 of the German Basic Law, every person has the right to life and bodily integrity, which rights can only be infringed on in accordance with the law. However, personhood and life are not defined.

    Full Text Available Objective. This research aimed to investigate the fertility management of women aged over 30 years prior to a termination of pregnancy (TOP to inform primary health care service delivery providers and policy makers. Design. An ethically approved, two-phase sequential explanatory mixed methods design was used. This paper reports on part of that study. Setting. The study was conducted in five South Australian TOP clinics. Patients. Women aged over 30 years attending for a TOP in 2009 were invited to participate. Interventions. The Contraception Sexual Attitude Questionnaire (modified version of women attending termination of pregnancy services was used. Main Outcomes Measures. Quantitative data analysis utilized SPSS V16 where simple descriptive statistics were described. Results. There were 101 questionnaire respondents where 70.5% were Australian women, predominantly married and with children. Women used contraception but experienced method failure, were beginning a new method, or were afraid of side effects. Risk-taking behaviours were reported such as putting the possibility of pregnancy out of their mind, getting carried away and not thinking of pregnancy risk, or frequently having unprotected intercourse. Conclusion. Service delivery needs to include age specific programs, and policy makers need to include policies which are adequately funded and evaluated. Further research is required to provide greater depth of knowledge in this area.

  9. Unaccompanied Immigrant Minors: Where to Begin.

    Ciaccia, Kimberly A; John, Rita Marie

    2016-01-01

    The number of unaccompanied immigrant minors (UIMs) from Central America significantly increased in 2014. Nearly 50,000 children from El Salvador, Guatemala, and Honduras crossed the United States-Mexico border in 2014, compared with 3,933 in 2011. Few resources exist to guide pediatric nurse practitioners (PNPs) in their care of UIM. The multifactorial reasons behind migration and the state of children's health in Central America provide insight into the needs of UIMs. Guidelines for similar groups such as foreign-born children and refugees offer direction for the health care considerations of UIMs. This article provides demographic information on UIMs, highlights the unique and challenging medical and mental health issues facing UIMs, and discusses the role of the PNP. A UIM's initial visit with a PNP serves as an opportunity to build trust through culturally competent, trauma-informed care, provide preventive care, assess for unmet health needs, and screen for mental health conditions.

    Ibrahim, Joseph G; Chen, Ming-Hui; Gwon, Yeongjin; Chen, Fang

    2015-12-10

    The power prior has been widely used in many applications covering a large number of disciplines. The power prior is intended to be an informative prior constructed from historical data. It has been used in clinical trials, genetics, health care, psychology, environmental health, engineering, economics, and business. It has also been applied for a wide variety of models and settings, both in the experimental design and analysis contexts. In this review article, we give an A-to-Z exposition of the power prior and its applications to date. We review its theoretical properties, variations in its formulation, statistical contexts for which it has been used, applications, and its advantages over other informative priors. We review models for which it has been used, including generalized linear models, survival models, and random effects models. Statistical areas where the power prior has been used include model selection, experimental design, hierarchical modeling, and conjugate priors. Frequentist properties of power priors in posterior inference are established, and a simulation study is conducted to further examine the empirical performance of the posterior estimates with power priors. Real data analyses are given illustrating the power prior as well as the use of the power prior in the Bayesian design of clinical trials. PMID:26346180

  17. Bayesian variable selection with spherically symmetric priors

    CERN Document Server

    De Kock, M B

    2014-01-01

    We propose that Bayesian variable selection for linear parametrisations with Gaussian iid likelihoods be based on the spherical symmetry of the diagonalised parameter space. This reduces the multidimensional parameter space problem to one dimension without the need for conjugate priors. Combining this likelihood with what we call the r-prior results in a framework in which we can derive closed forms for the evidence, posterior and characteristic function for four different r-priors, including the hyper-g prior and the Zellner-Siow prior, which are shown to be special cases of our r-prior. Two scenarios of a single variable dispersion parameter and of fixed dispersion are studied separately, and asymptotic forms comparable to the traditional information criteria are derived. In a simple simulation exercise, we find that model comparison based on our uniform r-prior appears to fare better than the current model comparison schemes.

  2. The beginning of uranium production in Estonia

    International Nuclear Information System (INIS)

    Large amounts of uranium available in the Estonian black alum (Dictyonema) shale created intense interest towards this low-grade ore in the very beginning of the atomic era. Various selective leaching and concentration technologies were tried with both roasted and native shale, at first at the Narva Pilot Plant and thereafter at the Sillamaee. Even though most of the USSR leading research and development centers participated in this effort, industrial uranium production turned out to be both technologically possible, but at the same time economically untenable at this time, just as it was the case in Sweden.

    1976-01-01

    The beginnings of behavior therapy with delinquents are traced to the early 1960's when a number of case studies and demonstration projects were first presented. Current practices are reviewed in more detail. In institutions for delinquents, many token economies have gradually developed; their shortcomings and results are discussed. In clinic settings, several individual and group techniques are reviewed as they are currently practiced. A major trend is seen as being away from institutional and traditional clinic behavior therapy. Direct community intervention is seen as the most parsimonious mode for modifying and preventing delinquent behavior, and several model programs are described.

    2015-11-01

    Deficiencies in beginning undergraduate students' basic mathematical skills has been an issue of concern in higher education, particularly in the past 15 years. This issue has been tracked and analysed in a number of universities in Ireland and internationally through student scores recorded in mathematics diagnostic tests. Students beginning their science-based and technology-based undergraduate courses in the University of Limerick have had their basic mathematics skills tested without any prior warning through a 40 question diagnostic test during their initial service mathematics lecture since 1998. Data gathered through this diagnostic test have been recorded in a database kept at the university and explored to track trends in mathematical competency of these beginning undergraduates. This paper details findings surrounding an analysis of the database between 2003 and 2013, outlining changes in mathematical competencies of these beginning undergraduates in an attempt to determine reasons for such changes. The analysis found that the proportion of students tested through this diagnostic test that are predicted to be at risk of failing their service mathematics end-of-semester examinations has increased significantly between 2003 and 2013. Furthermore, when students' performance in secondary level mathematics was controlled, it was determined that the performance of beginning undergraduates in 2013 was statistically significantly below that of the performance of the beginning undergraduates recorded 10 years previously.

    It was May of 1999. Having just turned 41 years old, I was on top of life. Adoring my role as a hands-on mom for our three young children, the oldest one deaf since birth, I enjoyed using my background in special education and psychology and my creativity and love for music, drama, and art. My work brought me fulfillment and gave tremendous meaning to my life. I was celebrating the publication of my first book for parents and professionals on helping children with special needs develop language skills, and giving book presentations was great. Between teaching college students majoring in special education and serving on the board of several committees to advocate for special education services for students, I was traveling, entertaining, playing guitar, and singing in a local choral group. I was on the move every minute of every day.

    We introduce a new shrinkage prior called the functional horseshoe prior that encourages shrinkage towards parametric classes of functions. Unlike existing shrinkage priors for parametric models, the shrinkage acts on the shape of the function rather than sparsity of model parameters. We compare its performance with classical nonparametric estimators and a number of penalized likelihood approaches, and we show that the proposed procedure outperforms the competitors in the considered simulatio...

    "Although we cannot observe them (and they may be forever inaccessible), other universes are a natural expectation from current cosmology. Moreover, many features of our universe that otherwise seem baffling fall into place once we recognize this." Sir Martin Rees, the British Astronomer Royal, gives a vivid, occasionally acid tour of current astrophysics and cosmology, with insights into scientific politics, such as the enormous increase in the cost of the space telescope because of its association with the Space Shuttle. He also offers keen observations on personalities such as Subrahmayan Chandrasekhar and Isaac Newton, Yakov Zeldovich and Albert Einstein. Joseph Silk calls Before the Beginning "an unusual blend of wit, asperity and cosmology ... a combination of clarity and conciseness."

Beginning next summer, the system will operate the two environmental satellites in DOD's Defense Meteorological Satellite Program. Under merger plans, NOAA will be responsible for operating the DOD satellite system as well as its own. The elimination of separate systems could save $678 million through fiscal year 1999, according to James Mannen, Director of the federal government's Integrated Program Office

    Use and creation of computer graphics can be effectively taught to beginning design students in the context of discipline-specific design projects. In particular, a case study of the pedagogy implemented by the New Jersey Institute of Technology's College of Architecture + Design provides examples of how teachers harness the students' desire to create and provide educational opportunities for undergraduates to learn about the use of digital media in the processes and products of design. Employing a carefully constructed sequence, students are exposed to (and use) computer applications for raster imaging, vector drawing, 3D modeling and rendering, and eventually building information modeling and time-based sequential representation all while producing original work through analysis and synthesis.

    Quality improvement involves a combined effort among health care staff and stakeholders to diagnose and treat problems in the health care system. However, health care professionals often lack training in quality improvement methods, which makes it challenging to participate in improvement efforts. This article familiarizes health care professionals with how to begin a quality improvement project. The initial steps involve forming an improvement team that possesses expertise in the quality of care problem, leadership, and change management. Stakeholder mapping and analysis are useful tools at this stage, and these are reviewed to help identify individuals who might have a vested interest in the project. Physician engagement is a particularly important component of project success, and the knowledge that patients/caregivers can offer as members of a quality improvement team should not be overlooked. After a team is formed, an improvement framework helps to organize the scientific process of system change. Common quality improvement frameworks include Six Sigma, Lean, and the Model for Improvement. These models are contrasted, with a focus on the Model for Improvement, because it is widely used and applicable to a variety of quality of care problems without advanced training. It involves three steps: setting aims to focus improvement, choosing a balanced set of measures to determine if improvement occurs, and testing new ideas to change the current process. These new ideas are evaluated using Plan-Do-Study-Act cycles, where knowledge is gained by testing changes and reflecting on their effect. To show the real world utility of the quality improvement methods discussed, they are applied to a hypothetical quality improvement initiative that aims to promote home dialysis (home hemodialysis and peritoneal dialysis). This provides an example that kidney health care professionals can use to begin their own quality improvement projects.

  16. Jazz Guitar Improvisation: Beginning with Guide-Tones

    Directory of Open Access Journals (Sweden)

    Daniel Andersen

    2010-12-01

    Full Text Available This article discusses an approach to teaching linear improvisation to beginning jazz guitarists through the function of voice leading in harmonic progressions. The student may gain a clear understanding of improvising melodies by establishing clear visual and aural relationships between the chordal and melodic textures. Three dominant 7th chord voicings are introduced and applied to a twelve bar blues progression in F major. After learning the rhythm guitar accompaniment, single note guide tones consisting of the flat 7th and 3rd chord tones of each dominant seventh chord are extracted from the chord voicings and applied in a melodic texture following chromatic voice leading principles within the harmonic progression. Musicality within the exercises is increased by the addition of a series of rhythmic variations that are applied to the guide-tone lines. Continuing with the concept, full dominant seventh arpeggios are introduced in order to expand the available note choices as a way to build a solid foundation for improvising within harmonic progressions prior to using diatonic scales.

    Directory of Open Access Journals (Sweden)

    Brenda Alston-Mills

    2012-12-01

    Full Text Available The perception of diversity and inclusion, as it relates to social justice, often evokes destructive responses, either spoken or unspoken. It is one of the ‘malicious problems’ found in the classroom, the workplace, and amongst other parts of our society. In challenging these problems with diversity and inclusion, conversations regarding the substantive aspects of oppression and inequitable distribution of power of one group over another must be initiated to educate or expand the thinking of our modern day society. Formulating solutions from these conversations, willing individuals must be able to name the issue, analyze its impact, and enact a positive change, while acknowledging the difficulties in creating conversations of an issue that is in dire need of revelation. This report provides a non-controversial presentation, beginning with reasons for resistance, followed by survival strategies, and ending with pro-active strategies to establish dialogue and to allow for personal stories. Further discussion will analyze aggressive behavior, examine critical core values for an individual and organization, discuss positive and effective methods for combating mistreatment, and empowerment strategies to respond positively to oppression. Strategies for engaging an organization are included, such as how to use these tools to co-create a vision for a welcoming environment in organizations, while acknowledging the uncomfortable atmosphere that surrounds the topic of cultural change. Accepting that this uncomfortable environment stems from fear itself, fear is a viable part of the process towards trust and resolution.

  20. Galen and the beginnings of Western physiology.

    Science.gov (United States)

    West, John B

    2014-07-15

    Galen (129-c. 216 AD) was a key figure in the early development of Western physiology. His teachings incorporated much of the ancient Greek traditions including the work of Hippocrates and Aristotle. Galen himself was a well-educated Greco-Roman physician and physiologist who at one time was a physician to the gladiators in Pergamon. Later he moved to Rome, where he was associated with the Roman emperors Marcus Aurelius and Lucius Verus. The Galenical school was responsible for voluminous writings, many of which are still extant. One emphasis was on the humors of the body, which were believed to be important in disease. Another was the cardiopulmonary system, including the belief that part of the blood from the right ventricle could enter the left through the interventricular septum. An extraordinary feature of these teachings is that they dominated thinking for some 1,300 years and became accepted as dogma by both the State and Church. One of the first anatomists to challenge the Galenical teachings was Andreas Vesalius, who produced a magnificent atlas of human anatomy in 1543. At about the same time Michael Servetus described the pulmonary transit of blood, but he was burned at the stake for heresy. Finally, with William Harvey and others in the first part of the 17th century, the beginnings of modern physiology emerged with an emphasis on hypotheses and experimental data. Nevertheless, vestiges of Galen's teaching survived into the 19th century. PMID:24879053

    Gardner, Jonathan

    2008-01-01

    Cosmology is the scientific study of how the Universe began more than 13 billion years ago, how its properties have changed, and what its future might be. The balance of forces and energy cause the Universe to expand, first accelerating, then decelerating and then accelerating again. Within this overall structure, the interplay of atoms and light with the mysterious dark matter and dark energy causes stars and galaxies to form and evolve, leading to galaxies like our own home, the Milky Way. Observational cosmology uses telescopes on Earth and in space to reach back in time to find the faint remaining echoes of the Big Bang and to trace the formation and evolution of the galaxies and structures that fill the Universe. In this lecture, Dr. Gradner will give an overview of cosmology, outlining the 13-billion year history of the Universe, and highlighting the very rapid progress this field has made i the last decade. He will discuss the role that NASA space telescopes have played in this progress and wil continue to play in the years to come. He will give a time-based history of the Universe, discussing the successive processes that formed matter, particles, atoms, stars and galaxies. In particular, he will focus on cosmological inflation, the rapid accelerated expansion that marks the beginning of the Universe, and dark energy, a tenuous substance that overcomes gravity and whose properties will determine its final fate.

  2. Is cloud computing finally beginning to mature?

    Dimitrios Zissis

    2012-10-01

    Full Text Available The buzz term that came into popularity in the beginning of 2006 to describe an innovative IT deployment architecture, originated from the cloud metaphor that was used to represent the Internet in various network diagrams as early as the 1990s. In a short period of time after the term appeared, cloud solutions were being rapidly marketed by many IT companies and various new buzz words came into vogue such as "cloud in a can", "cloud bursting", and we suddenly had “blue clouds”, “green clouds”, “white label cloud services” and many others. We witnessed what is now being labeled as "cloud washing", the attempts of many vendors to strap the cloud term onto their traditional products, which became the source of huge disambiguation, conflicts and misunderstandings. Today, the term “cloud computing” is everywhere. A quick search on Google for the term “cloud computing” will return 267 million search results. Cloud computing is being marketed as the complex-free efficient method of accessing huge amounts of computing and storage as a service. Behind the curtains though, cloud computing has often been called a huge leap of faith and concerns were fuelled when reports started to surface of random failures (e.g. power outages and shortcomings of cloud infrastructures. Small black clouds of uncertainty have appeared in the otherwise clear skies of cloud computing

    When a one-dimensional luminance scalar is replaced by a vector of a colorful multi-dimension for every pixel of a monochrome image,the process is called colorization.However,colorization is under-constrained.Therefore,the prior knowledge is considered and given to the monochrome image.Colorization using optimization algorithm is an effective algorithm for the above problem.However,it cannot effectively do with some images well without repeating experiments for confirming the place of scribbles.In this paper,a colorization algorithm is proposed,which can automatically generate the prior knowledge.The idea is that firstly,the prior knowledge crystallizes into some points of the prior knowledge which is automatically extracted by downsampling and upsampling method.And then some points of the prior knowledge are classified and given with corresponding colors.Lastly,the color image can be obtained by the color points of the prior knowledge.It is demonstrated that the proposal can not only effectively generate the prior knowledge but also colorize the monochrome image according to requirements of user with some experiments.

  5. Spirit Begins Drive Around Home Plate

    The hazard avoidance camera on the front of NASA's Mars Exploration Rover Spirit took this image after a drive by Spirit on the 1,829th Martian day, or sol, of Spirit's mission on the surface of Mars (Feb. 24, 2009). On Sol 1829, Spirit drove 6.29 meters (21 feet) northwestward, away from the northern edge of the low plateau called 'Home Plate.' The track dug by the dragged right-front wheel as the rover drove backward is visible in this image, receding toward the southeast. Rock layers of the northern slope of Home Plate are visible in the upper right portion of the image. In sols prior to 1829, the rover team had been trying to maneuver Spirit to climb onto the northern edge of Home Plate, ready to drive southward across the top of the plateau toward science destinations south of Home Plate. The Sol 1829 drive was the first move of a revised strategy to circle at least partway around Home Plate on the trek toward the sites south of the plateau.

    Full Text Available Location estimation of tourist photos by classifi­cation is challenging due to the unstable and less-discriminative features of photos taken in each city. In this paper, we originally deal with this issue in an alternative way, which begins with but is not limited to classification. We explore textual, temporal, geographic as well as visual information to make tour route recommendation. Given a query photo, we recommend a city by first classifying the photo to get scores that indicate its similarities with photos from each city, and then evaluating the attractiveness of each city by modeling its hotness potential. We do not aim at finding out where the photo was taken exactly; instead, we combine the similarity and hotness potentials according to the user’s preference and recommend the city that has the highest combination value. Then, we suggest the next city by further modeling the correlation and interaction between cities pairwise with two potentials, i.e., proximity and co-visitedness. Applying the greedy algorithm, we recommend one city at a time and eventually generate a tour route consist­ing of all the recommended cities in order. Furthermore, in order to show different visual and cultural character­istics across cities, we classify photos of each city into four categories, i.e., food, landscape, man-made and person. In experiments, we collected a database containing 41792 photos of 35 important cities along the silkroad and provided a query sample for tour route recommendation. Experimental results have shown the effectiveness and reliability of our recommendation model.

  7. Terminology for pregnancy loss prior to viability

    Pregnancy loss prior to viability is common and research in the field is extensive. Unfortunately, terminology in the literature is inconsistent. The lack of consensus regarding nomenclature and classification of pregnancy loss prior to viability makes it difficult to compare study results from...... different centres. In our opinion, terminology and definitions should be based on clinical findings, and when possible, transvaginal ultrasound. With this Early Pregnancy Consensus Statement, it is our goal to provide clear and consistent terminology for pregnancy loss prior to viability....

  8. Reasons for (prior) belief in bayesian epistemology

    OpenAIRE

    2012-01-01

    Bayesian epistemology tells us with great precision how we should move from prior to posterior beliefs in light of new evidence or information, but says little about where our prior beliefs come from. It o¤ers few resources to describe some prior beliefs as rational or well-justi�ed, and others as irrational or unreasonable. A di¤erent strand of epistemology takes the central epistemological question to be not how to change one�s beliefs in light of new evidence, but what reasons justify a gi...

    2013-08-01

    In early mandatory Israel, orthopedics was mainly conservative, The first modern orthopedic surgeon was Ernst Spira from Czechoslovakia who established an orthopedic service at the Beilinson Hospital in Petah Tikva and left in 1948 to establish the Orthopedic Department and the Rehabilitation Center in Tel Hashomer, which treated the War of Independence casualties including amputees and victims of spinal cord injuries. A second orthopedic department was opened in Tel Hashomer by Shmuel Weissman who left in 1961 to open the Orthopedic Department at the Ichilov hospital in Tel Aviv. Shmuel Weissman became the first Chairman of Orthopedic Surgery at the Tel Aviv University medical school. In 1955, Myer Makin opened a modern orthopedic department in the Hadassah Hospital in Jerusalem and the Alyn Hospital for crippled children. In 1951, Assaf Harofeh Hospital opened the Department of Orthopedic Surgery headed by Anatol Axer who specialized in the treatment and rehabilitation of polio patients. The majority of the second generation of orthopedic department directors was trained by these four surgeons. Major developments in the 1960s and 1970s were the introduction of the AO system revolutionizing fracture treatment from conservative to operative treatment, the advent of total hip and knee replacements, Harrington instrumentation in spinal surgery and arthroscopy were major advances in orthopedic patient care brought to Israel by the aforementioned second generation of orthopedic surgeons. Hand surgery became an independent subspecialty of orthopedics and was lead by the internationally renowned hand surgeon, Isidore Kessler. PMID:24167938

  15. Varying prior information in Bayesian inversion

    Science.gov (United States)

    Walker, Matthew; Curtis, Andrew

    2014-06-01

    Bayes' rule is used to combine likelihood and prior probability distributions. The former represents knowledge derived from new data, the latter represents pre-existing knowledge; the Bayesian combination is the so-called posterior distribution, representing the resultant new state of knowledge. While varying the likelihood due to differing data observations is common, there are also situations where the prior distribution must be changed or replaced repeatedly. For example, in mixture density neural network (MDN) inversion, using current methods the neural network employed for inversion needs to be retrained every time prior information changes. We develop a method of prior replacement to vary the prior without re-training the network. Thus the efficiency of MDN inversions can be increased, typically by orders of magnitude when applied to geophysical problems. We demonstrate this for the inversion of seismic attributes in a synthetic subsurface geological reservoir model. We also present results which suggest that prior replacement can be used to control the statistical properties (such as variance) of the final estimate of the posterior in more general (e.g., Monte Carlo based) inverse problem solutions.

    Pagliaro, Claudia M; Kritzer, Karen L

    2013-04-01

    Over decades and across grade levels, deaf/hard-of-hearing (d/hh) student performance in mathematics has shown a gap in achievement. It is unclear, however, exactly when this gap begins to emerge and in what areas. This study describes preschool d/hh children's knowledge of early mathematics concepts. Both standardized and nonstandardized measures were used to assess understanding in number, geometry, measurement, problem solving, and patterns, reasoning and algebra. Results present strong evidence that d/hh students' difficulty in mathematics may begin prior to the start of formal schooling. Findings also show areas of strength (geometry) and weakness (problem solving and measurement) for these children. Evidence of poor foundational performance may relate to later academic achievement.

  1. GENERAL ASPECTS REGARDING THE PRIOR DISCIPLINARY RESEARCH

    Directory of Open Access Journals (Sweden)

    ANDRA PURAN (DASCĂLU

    2012-05-01

    Full Text Available Disciplinary research is the first phase of the disciplinary action. According to art. 251 paragraph 1 of the Labour Code no disciplinary sanction may be ordered before performing the prior disciplinary research.These regulations provide an exception: the sanction of written warning. The current regulations in question, kept from the old regulation, provides a protection for employees against abuses made by employers, since sanctions are affecting the salary or the position held, or even the development of individual employment contract. Thus, prior research of the fact that is a misconduct, before a disciplinary sanction is applied, is an essential condition for the validity of the measure ordered. Through this study we try to highlight some general issues concerning the characteristics, processes and effects of prior disciplinary research.

  2. Generative Prior Knowledge for Discriminative Classification

    CERN Document Server

    DeJong, G; 10.1613/jair.1934

    2011-01-01

    We present a novel framework for integrating prior knowledge into discriminative classifiers. Our framework allows discriminative classifiers such as Support Vector Machines (SVMs) to utilize prior knowledge specified in the generative setting. The dual objective of fitting the data and respecting prior knowledge is formulated as a bilevel program, which is solved (approximately) via iterative application of second-order cone programming. To test our approach, we consider the problem of using WordNet (a semantic database of English language) to improve low-sample classification accuracy of newsgroup categorization. WordNet is viewed as an approximate, but readily available source of background knowledge, and our framework is capable of utilizing it in a flexible way.

Moreover, we define an iterative schema that allows for multiple points of reference, a possibility noted by Prior and demanded by Comrie, and sketch how this schema can be generalized to a shift-and-restrict paradigm in which special propositional symbols (for adverbials and indexicals) act as restrictors...

  4. Numbers and prior knowledge in sentence comprehension

    2013-01-01

    Full Text Available We evaluated whether the comprehension of sentences that contained numerical information could benefit from presenting numbers in Arabic format and from using prior knowledge. Participants read sentences including numbers (Arabic digits or number words while the comprehension accuracy was evaluated. In addition, the sentences were biased or unbiased by people's prior knowledge about quantities. The results showed better comprehension for sentences that contained Arabic digits as compared to number words. Moreover, biased sentences were understood more accurately than unbiased sentences. These results indicate that information about magnitude in sentence context is comprehended better when quantities are presented in Arabic format and when they are associated with participants' world knowledge.

  15. Genome position specific priors for genomic prediction

    Directory of Open Access Journals (Sweden)

    Brøndum Rasmus

    2012-10-01

    Full Text Available Abstract Background The accuracy of genomic prediction is highly dependent on the size of the reference population. For small populations, including information from other populations could improve this accuracy. The usual strategy is to pool data from different populations; however, this has not proven as successful as hoped for with distantly related breeds. BayesRS is a novel approach to share information across populations for genomic predictions. The approach allows information to be captured even where the phase of SNP alleles and casuative mutation alleles are reversed across populations, or the actual casuative mutation is different between the populations but affects the same gene. Proportions of a four-distribution mixture for SNP effects in segments of fixed size along the genome are derived from one population and set as location specific prior proportions of distributions of SNP effects for the target population. The model was tested using dairy cattle populations of different breeds: 540 Australian Jersey bulls, 2297 Australian Holstein bulls and 5214 Nordic Holstein bulls. The traits studied were protein-, fat- and milk yield. Genotypic data was Illumina 777K SNPs, real or imputed. Results Results showed an increase in accuracy of up to 3.5% for the Jersey population when using BayesRS with a prior derived from Australian Holstein compared to a model without location specific priors. The increase in accuracy was however lower than was achieved when reference populations were combined to estimate SNP effects, except in the case of fat yield. The small size of the Jersey validation set meant that these improvements in accuracy were not significant using a Hotelling-Williams t-test at the 5% level. An increase in accuracy of 1-2% for all traits was observed in the Australian Holstein population when using a prior derived from the Nordic Holstein population compared to using no prior information. These improvements were significant (P

  1. Image Segmentation Using Weak Shape Priors

    CERN Document Server

    Xu, Robert Sheng; Salama, Magdy

    2010-01-01

    The problem of image segmentation is known to become particularly challenging in the case of partial occlusion of the object(s) of interest, background clutter, and the presence of strong noise. To overcome this problem, the present paper introduces a novel approach segmentation through the use of "weak" shape priors. Specifically, in the proposed method, an segmenting active contour is constrained to converge to a configuration at which its geometric parameters attain their empirical probability densities closely matching the corresponding model densities that are learned based on training samples. It is shown through numerical experiments that the proposed shape modeling can be regarded as "weak" in the sense that it minimally influences the segmentation, which is allowed to be dominated by data-related forces. On the other hand, the priors provide sufficient constraints to regularize the convergence of segmentation, while requiring substantially smaller training sets to yield less biased results as compare...

    Guided by the Federal Family Support Act of 1988 and the Job Opportunity and Basic Skills Program (JOBS), welfare reform initiatives on state and local levels were designed to foster employability among the public assistance population. Reform has focused on enhancing the supply of labor rather than the demand for labor as a route to labor force participation for the public assistance population. Program reforms assume that, by providing job training, educational services, and training-related expenses, labor market entry of the participating clientele would be facilitated while caseloads and public expenditures would decline. To date, analysis of similar programs in many states indicates that the impact of such programs in reducing public assistance caseloads is marginal. In New York City, despite the large investment of public funds in such programs, prior to this study the outcome of program implementation remained largely unknown. This study evaluates New York City's BEGIN program outcome target defined as the ability of the program to move welfare clients off public assistance and into the labor market. While the results of the study indicate that New York City's BEGIN program does not improve client's odds of leaving welfare, when compared to the odds of a non-participation client, there are several significant findings. The impact of program participation can be distinguished among distinct age groups. While older clients responded positively to BEGIN participation, access to day care was the only factor that significantly improved the probability that clients younger than 36 years of age would leave the welfare rolls within a two-year period. In response to the findings, the researchers suggest that future welfare reform efforts should grant localities broader flexibility to determine their own target population so that resources can be allocated to those groups that are most likely to benefit from specific programs.

    2007-01-01

    Subtraction of aligned images is a means to asses changes in a wide variety of clinical applications. In this paper the information theoretical origin of Mutual Information is explored. The parallelism between the problem of image registration and its characterization as a communication channel is found to be limiting. The concept of Mutual Information (MI) is extended to Focussed Mutual Information (FMI) to incorporate prior knowledge. Several methodologies are proposed to address specific registration problems, incorporating FMI. These methods are demonstrated by means of some elucidating examples.

  12. Diversity Priors for Learning Early Visual Features

    2015-08-01

    Full Text Available This paper investigates how utilizing diversity priors can discover early visual features thatresemble their biological counterparts. The study is mainly motivated by the sparsity andselectivity of activations of visual neurons in area V1. Most previous work on computationalmodeling emphasizes selectivity or sparsity independently. However, we argue that selectivityand sparsity are just two epiphenomena of the diversity of receptive fields, which has been rarelyexploited in learning. In this paper, to verify our hypothesis, restricted Boltzmann machines(RBMs are employed to learn early visual features by modeling the statistics of natural images.Considering RBMs as neural networks, the receptive fields of neurons are formed by the inter-weights between hidden and visible nodes. Due to the conditional independence in RBMs, thereis no mechanism to coordinate the activations of individual neurons or the whole population.A diversity prior is introduced in this paper for training RBMs. We find that the diversity priorindeed can assure simultaneously sparsity and selectivity of neuron activations. The learnedreceptive fields yield a high degree of biological similarity in comparison to physiological data.Also, corresponding visual features display a good generative capability in image reconstruction.

    2014-01-01

    We investigate the prior dependence on the inferred spectrum of primordial tensor perturbations, in light of recent results from BICEP2 and taking into account a possible dust contribution to polarized anisotropies. We highlight an optimized parameterization of the tensor power spectrum, and adoption of a logarithmic prior on its amplitude $A_T$, leading to results that transform more evenly under change of pivot scale. In the absence of foregrounds the tension between the results of BICEP2 and Planck drives the tensor spectral index $n_T$ to be blue-tilted in a joint analysis, which would be in contradiction to the standard inflation prediction ($n_T<0$). When foregrounds are accounted for, the BICEP2 results no longer require non-standard inflationary parameter regions. We present limits on primordial $A_T$ and $n_T$, adopting foreground scenarios put forward by Mortonson & Seljak and motivated by Planck 353 GHz observations, and assess what dust contribution leaves a detectable cosmological signal. ...

  14. Movement speed is biased by prior experience

    2013-01-01

    How does the motor system choose the speed for any given movement? Many current models assume a process that finds the optimal balance between the costs of moving fast and the rewards of achieving the goal. Here, we show that such models also need to take into account a prior representation of preferred movement speed, which can be changed by prolonged practice. In a time-constrained reaching task, human participants made 25-cm reaching movements within 300, 500, 700, or 900 ms. They were then trained for 3 days to execute the movement at either the slowest (900-ms) or fastest (300-ms) speed. When retested on the 4th day, movements executed under all four time constraints were biased toward the speed of the trained movement. In addition, trial-to-trial variation in speed of the trained movement was significantly reduced. These findings are indicative of a use-dependent mechanism that biases the selection of speed. Reduced speed variability was also associated with reduced errors in movement amplitude for the fast training group, which generalized nearly fully to a new movement direction. In contrast, changes in perpendicular error were specific to the trained direction. In sum, our results suggest the existence of a relatively stable but modifiable prior of preferred movement speed that influences the choice of movement speed under a range of task constraints.

    The brain generates a representation of our environment by integrating signals from a common source, but segregating signals from different sources. This fMRI study investigated how the brain arbitrates between perceptual integration and segregation based on top-down congruency expectations and bottom-up stimulus-bound congruency cues. Participants were presented audiovisual movies of phonologically congruent, incongruent or McGurk syllables that can be integrated into an illusory percept (e.g. "ti" percept for visual «ki» with auditory /pi/). They reported the syllable they perceived. Critically, we manipulated participants' top-down congruency expectations by presenting McGurk stimuli embedded in blocks of congruent or incongruent syllables. Behaviorally, participants were more likely to fuse audiovisual signals into an illusory McGurk percept in congruent than incongruent contexts. At the neural level, the left inferior frontal sulcus (lIFS) showed increased activations for bottom-up incongruent relative to congruent inputs. Moreover, lIFS activations were increased for physically identical McGurk stimuli, when participants segregated the audiovisual signals and reported their auditory percept. Critically, this activation increase for perceptual segregation was amplified when participants expected audiovisually incongruent signals based on prior sensory experience. Collectively, our results demonstrate that the lIFS combines top-down prior (in)congruency expectations with bottom-up (in)congruency cues to arbitrate between multisensory integration and segregation.

    2010-03-01

    Full Text Available Young Canadian boys and girls aged nine to eleven were asked to consider their personal futures, the future of their community and the future of the world. Mixed methods were employed for data collection and analysis. Responses were compared with those given bychildren in eight countries and the discussion focused on the importance prior knowledge, in this case, prior knowledge of global issues, holds for effective teaching and learning about global issues. Canadian children were optimistic about the future for themselves and their community but less so for the globe. More so than other children, Canadian children were concerned with issues of social justice, issues such as discrimination and racism, and withimproving the environment, which might be attributed to the emphasis that is placed on these issues in their school curriculum. Assessing prior knowledge should be a priority for those considering development and implementation of global education curricula.

  1. Improving semantic scene understanding using prior information

    Science.gov (United States)

    Laddha, Ankit; Hebert, Martial

    2016-05-01

    Perception for ground robot mobility requires automatic generation of descriptions of the robot's surroundings from sensor input (cameras, LADARs, etc.). Effective techniques for scene understanding have been developed, but they are generally purely bottom-up in that they rely entirely on classifying features from the input data based on learned models. In fact, perception systems for ground robots have a lot of information at their disposal from knowledge about the domain and the task. For example, a robot in urban environments might have access to approximate maps that can guide the scene interpretation process. In this paper, we explore practical ways to combine such prior information with state of the art scene understanding approaches.

  2. Dyslexics' usage of visual priors is impaired.

    2016-07-01

    Human perception benefits substantially from familiarity, via the formation of effective predictions of the environment's pattern of stimulation. Basic stimulation characteristics are automatically retrieved and integrated into our perception. A quantitatively measurable manifestation of the integration of priors is known as "contraction to the mean"; i.e., perception is biased toward the experienced mean. We previously showed that in the context of auditory discrimination, the magnitude of this bias is smaller among dyslexic individuals than among good readers matched for age and general reasoning skills. Here we examined whether a similarly reduced contraction characterizes dyslexics' behavior on serial visual tasks. Using serial spatial frequency discrimination tasks, we found that dyslexics' bias toward the experiment's mean spatial frequency was smaller than that observed for the controls. Thus, dyslexics' difficulties in automatic detection and integration of stimulus statistics are domain-general. These difficulties are likely to impede the acquisition of reading expertise.

    2015-09-01

    The influential framework of 'predictive processing' suggests that prior probabilistic expectations influence, or even constitute, perceptual contents. This notion is evidenced by the facilitation of low-level perceptual processing by expectations. However, whether expectations can facilitate high-level components of perception remains unclear. We addressed this question by considering the influence of expectations on perceptual metacognition. To isolate the effects of expectation from those of attention we used a novel factorial design: expectation was manipulated by changing the probability that a Gabor target would be presented; attention was manipulated by instructing participants to perform or ignore a concurrent visual search task. We found that, independently of attention, metacognition improved when yes/no responses were congruent with expectations of target presence/absence. Results were modeled under a novel Bayesian signal detection theoretic framework which integrates bottom-up signal propagation with top-down influences, to provide a unified description of the mechanisms underlying perceptual decision and metacognition.

  4. NMR spectral analysis using prior knowledge

    Kasai, Takuma; Nagata, Kenji; Okada, Masato; Kigawa, Takanori

    2016-03-01

    Signal assignment is a fundamental step for analyses of protein structure and dynamics with nuclear magnetic resonance (NMR). Main-chain signal assignment is achieved with a sequential assignment method and/or an amino-acid selective stable isotope labeling (AASIL) method. Combinatorial selective labeling (CSL) methods, as well as our labeling strategy, stable isotope encoding (SiCode), were developed to reduce the required number of labeled samples, since one of the drawbacks of AASIL is that many samples are needed. Signal overlapping in NMR spectra interferes with amino-acid determination by CSL and SiCode. Since spectral deconvolution by peak fitting with a gradient method cannot resolve closely overlapped signals, we developed a new method to perform both peak fitting and amino acid determination simultaneously, with a replica exchange Monte Carlo method, incorporating prior knowledge of stable-isotope labeling ratios and the amino-acid sequence of the protein.

    Background The accuracy of genomic prediction is highly dependent on the size of the reference population. For small populations, including information from other populations could improve this accuracy. The usual strategy is to pool data from different populations; however, this has not proven...... as successful as hoped for with distantly related breeds. BayesRS is a novel approach to share information across populations for genomic predictions. The approach allows information to be captured even where the phase of SNP alleles and casual mutation alleles are reversed across populations, or the actual...... casual mutation is different between the populations but affects the same gene. Proportions of a four-distribution mixture for SNP effects in segments of fixed size along the genome are derived from one population and set as location specific prior proportions of distributions of SNP effects...

    The first galaxies in the Universe are the building blocks of all observed galaxies. We present scaling relations for galaxies forming at redshifts $z \\ge 15$ when reionization is just beginning. We utilize the ``Rarepeak' cosmological radiation hydrodynamics simulation that captures the complete star formation history in over 3,300 galaxies, starting with massive Population III stars that form in dark matter halos as small as ~$10^6 M_\\odot$. We make various correlations between the bulk halo quantities, such as virial, gas, and stellar masses and metallicities and their respective accretion rates, quantifying a variety of properties of the first galaxies up to halo masses of $10^9 M_\\odot$. Galaxy formation is not solely relegated to atomic cooling halos with virial temperatures greater than $10^4$ K, where we find a dichotomy in galaxy properties between halos above and below this critical mass scale. Halos below the atomic cooling limit have a stellar mass -- halo mass relationship $\\log M_\\star \\simeq 3....

    2015-12-01

    Full Text Available This article explores the context and experiences of three beginning teachers in their effort to improve their teaching and to implement and align themselves with their schools’ expectations of effective teaching practices. Research findings emerging from a sociocultural-ethnographic framework revealed that participants challenged their own beliefs about effective teaching practices in aligning themselves with their schools’ expectations. In complying with routine expectations, they embraced predominantly teacher-centred practices, rather than a student-centred approach. Given the ongoing effort to augment the quality of education in the Seychelles, beginning teachers’ implementation of and access to evidenced-based practices could be recognised as part of this endeavour.

  16. Capitation payments based on prior hospitalizations.

    Science.gov (United States)

    van Vliet, R C; van de Ven, W P

    1993-07-01

    In many countries the concept of capitating health care insurers is receiving increasing attention. In a competitive environment, capitation should induce insurers to concentrate more on cost containment instead of indulging in risk selection. The necessary premium-replacing capitation payments should account for predictable variations in annual per-person health care expenditures as far as these are related to health status. Various studies have shown that crude capitation models based on e.g. age, sex and place of residence, do not reflect expected costs accurately. This implies inefficient pricing possibly leading to risk selection and windfall profits or losses for insurers, thereby undermining the objectives of a capitation system. Using Dutch micro data on some 200,000 individuals, this article stimulates various alternative capitation models based on, among others, diagnostic information from previous hospitalizations. Results suggest that the problems of both risk selection and windfall profits/losses may be mitigated substantially by using this type of information together with data on prior costs. These results are not only relevant for situations where competing insurers are capitated, as intended in the Netherlands, but also when providers are capitated, as in the UK, or when HMOs are capitated, as in the US.

    The 2016 Kumamoto earthquakes occurred under circumstance that seismicity remains high in all parts of Japan since the 2011 Tohoku-Oki earthquake. Identifying what happened before this incident is one starting point for promote earthquake forecast research to prepare for subsequent large earthquakes in the near future in Japan. Here we report precursory seismic patterns prior to the Kumamoto earthquakes, measured by four different methods based on seismicity changes that can be used for earthquake forecasting: b-value method, two kinds of seismic quiescence evaluation methods, and a method of detailed foreshock evaluation. The spatial extent of precursory patterns differs from one method to the other and ranges from local scales (typically asperity size), to regional scales (e.g., 2{\\deg} x 3{\\deg} around the source zone). The earthquakes are preceded by periods of pronounced anomalies, which lasted decade scales (e.g., 20 years or longer) to yearly scales (e.g., 1~2 years). We demonstrate that combination of...

  16. Beginning science teachers' performances: Assessment in times of reform

    Science.gov (United States)

    Budzinsky, Fie K.

    2000-10-01

    The current reform in science education and the research on effective teaching and student learning have reinforced the importance of teacher competency. To better measure performances in the teaching of science, performance assessment has been added to Connecticut's licensure process for beginning science teachers. Teaching portfolios are used to document teaching and learning over time. Portfolios, however, are not without problems. One of the major concerns with the portfolio assessment process is its subjectivity. Assessors may not have opportunities to ask clarifying or follow-up questions to enhance the interpretation of a teacher's performance. In addition, portfolios often contain components based on self-documentation, which are subjective. Furthermore, the use of portfolios raises test equity issues. These concerns present challenges for persons in charge of establishing the validity of a portfolio-based licensure process. In high-stakes decision processes, such as teaching licensure, the validity of the assessment instruments must be studied. The primary purpose of this study was to explore the criterion-related validity of the Connecticut State Department of Education's Beginning Science Teaching Portfolio by comparing the interpretations of performances from science teaching portfolios to those derived from another assessment method, the Expert Science Teaching Educational and Evaluation Model, (ESTEEM). The analysis of correlations between the Beginning Science Teaching Portfolio and ESTEEM instrument scores was the primary method for establishing support for validity. The results indicated moderate correlations between all Beginning Science Teaching Portfolio and ESTEEM category and total variables. Multiple regression was used to examine whether differences existed in beginning science teachers' performances based on gender, poverty group, school level, and science discipline taught. None of these variables significantly contributed to the

  19. Experience revising an advanced-undergraduate/beginning-graduate fluid mechanics textbook

    Science.gov (United States)

    Dowling, David

    2012-11-01

    In the fall of 2009, Elsevier Inc. approached me about taking over as the lead author of the fluid mechanics textbook by P. K. Kundu and I. M. Cohen. I subsequently agreed and this presentation provides the story of the process and the approach taken to revising this fluid mechanics textbook which has been in print for approximately 15 years. The goal of the revision was to produce an excellent textbook for second courses in fluid mechanics taken by advanced undergraduate and beginning graduate students while maintaining the book's appeal to instructors who used prior editions. Thus, I sought to maintain or expand the text's fluid mechanics content, while adjusting the text's tone so that this content might be more readily reached by students who may have had only one prior course in fluid mechanics, or who may not specialize in fluid mechanics but do possess appropriate mathematical skills. The entire revision process involved seven steps: (i) formulating a revision plan that was independently reviewed, (ii) agreeing to a formal contract with deadlines, (iii) revising the text, figures, and front matter, (iv) proof reading and correcting copy-edited text, (v) correcting page proofs, (vi) generating the solutions manual, and (vii) tabulating errata.

    2004-01-01

    Digital communication is crucial for space endeavors. Jt transmits scientific and command data between earth stations and the spacecraft crew. It facilitates communications between astronauts, and provides live coverage during all phases of the mission. Digital communications provide ground stations and spacecraft crew precise data on the spacecraft position throughout the entire mission. Lessons learned from prior space missions are valuable for our new lunar and Mars missions set by our president s speech. These data will save our agency time and money, and set course our current developing technologies. Limitations on digital communications equipment pertaining mass, volume, data rate, frequency, antenna type and size, modulation, format, and power in the passed space missions are of particular interest. This activity is in support of ongoing communication architectural studies pertaining to robotic and human lunar exploration. The design capabilities and functionalities will depend on the space and power allocated for digital communication equipment. My contribution will be gathering these data, write a report, and present it to Communications Technology Division Staff. Antenna design is very carefully studied for each mission scenario. Currently, Phased array antennas are being developed for the lunar mission. Phased array antennas use little power, and electronically steer a beam instead of DC motors. There are 615 patches in the phased array antenna. These patches have to be modified to have high yield. 50 patches were created for testing. My part is to assist in the characterization of these patch antennas, and determine whether or not certain modifications to quartz micro-strip patch radiators result in a significant yield to warrant proceeding with repairs to the prototype 19 GHz ferroelectric reflect-array antenna. This work requires learning how to calibrate an automatic network, and mounting and testing antennas in coaxial fixtures. The purpose of this

    Full Text Available Abstract Background Selective learning is the ability to select items of relevance from among less important items. Limited evidence exists regarding the efficiency with which children with spina bifida-myelomeningocele and shunted hydrocephalus (SB/SH are able to learn information. This report describes initial data related to components of learning and metacognitive skills in children with SB/SH. Methods Twenty six children with SB/SH and 26 controls (age: 7 – 16 y with average intelligence, and monolingual English-speaking backgrounds participated in the study. Exclusion criteria for the SB/SH group were: prior history of shunt infection, history of seizure or shunt malfunction within the previous three months, prior diagnoses of attention disorders and/or clinical depression. Children were presented lists of words with equal exemplars each of two distinct semantic categories (e.g. fruits, animals, and told to make as high a score as possible by learning the words. The value of the words was designated by category membership (e.g. animals = low value; fruits = high value. The total number of words learned across three learning trials was used to determine memory span. Selective learning efficiency (SLE was computed as the efficiency with which items of greater value were selectively learned across three trials. Results Children with SB/SH did worse than controls on memory span (P Conclusion Success in school is often dependent on the ability to recall important facts selectively and ignore less important information. Children with SB/SH in our study had a poor memory span and were unable to monitor and report an efficient and workable metacognitive strategy required to remember a list of words. Preliminary findings may begin to explain our previous clinical and research findings wherein children with SB/SH often focus on extraneous details, but demonstrate difficulty remembering the main gist of a story/event.

    2003-03-01

    One of the most controversial topics in modern bioethics, science, and philosophy is the beginning of individual human life. In the seemingly endless debate, strongly stimulated, by recent technologic advances in human reproduction, a synthesis between scientific data and hypothesis, philosophical thought, and issues of humanities has become a necessity to deal with ethical, juridical, and social problems. Furthermore, in this field there is a temptation to ask science to choose between opinions and beliefs, which neutralize one another. The question of when human life begins requires the essential aid of different forms of knowledge. Here we become involved in the juncture between science and religion, which needs to be carefully explored. PMID:12696784

    2006-01-01

    The Tender Beginnings program demonstrates a comprehensive educational plan for maternity patients that can be extended throughout pregnancy, the birth process, and into the postpartum period. In today's healthcare environment, where the maternity patient continues to experience a shortened stay structure, the hurried learning process that is absorbed over a 48-hour stay is often ineffectual. This program provides a strategy and framework for effective teaching that can be successfully implemented all through the peripartum period. Budgetary constraints have given way to an innovative approach and opportunity for the healthcare specialist to explore an entrepreneurial relationship within the structure of the program. The Tender Beginnings program has proven to be a true integration of community educational outreach, nurse entrepreneurship, hospital-based education, and postpartum/neonatal follow-up.

    Full Text Available Haemophilus influenzae is one of the most important bacterial agents of otitis and sinusitis. H. influenzae type b (Hib is one of the main causes of meningitis, pneumonia, and septicemia in nonvaccinated children under 6 years of age. The aims of this study were to determine the prevalence of H. influenzae and Hib oropharyngeal colonization prior to the onset of the Hib vaccination program in Brazil in previously healthy children and to assess the susceptibility profile of this microorganism to a selected group of antimicrobials that are used to treat acute respiratory infections. METHOD: Cultures of Haemophilus influenzae were made from oropharynx swabs from 987 children under 6 years of age who were enrolled in 29 day-care centers in Taubaté (a city of São Paulo state, Brazil between July and December 1998. RESULTS: The prevalence of H. influenzae carriers was 17.4%, and only 5.5% of the strains were beta-lactamase producers. The prevalence of Hib carriers was high, 7.3% on average (range, 0.0 - 33.3%. CONCLUSIONS: The low prevalence of colonization by penicillin-resistant strains indicates that it is not necessary to substitute ampicilin or amoxicilin to effectively treat otitis and sinusitis caused by H. influenzae in Taubaté.Haemophilus influenzae é um dos mais importantes agentes bacterianos de otites e sinusites. Em crianças menores de seis anos de idade não vacinadas contra o H. influenzae do tipo b (Hib, essa bactéria é uma das principais causadoras de meningite, pneumonia e sepse. O objetivo deste estudo foi determinar a prevalência da colonização da orofaringe de crianças previamente saudáveis por H. influenzae e Hib e avaliar o perfil de suscetibilidade desses microorganismos a um grupo seleto de antimicrobianos, que habitualmente são utilizados para tratar as infecções respiratórias agudas.

  14. Comparison of no-prior and soft-prior regularization in biomedical microwave imaging

    2011-01-01

    Full Text Available Microwave imaging for medical applications is attractive because the range of dielectric properties of different soft tissues can be substantial. Breast cancer detection and monitoring of treatment response are areas where this technology could be important because of the contrast between normal and malignant tissue. Unfortunately, the technique is unable to achieve the high spatial resolution at depth in tissue which is available from other conventional modalities such as x-ray computed tomography (CT or magnetic resonance imaging (MRI. We have incorporated a soft-prior regularization strategy within our microwave reconstruction algorithm and compared it with the images obtained with traditional no-prior (Levenberg-Marquardt regularization. Initial simulation and phantom results show a significant improvement of the recovered electrical properties. Specifically, errors in the microwave property estimates were improved by as much as 95%. The effects of a false-inclusion region were also evaluated and the results show that a small residual property bias of 6% in permittivity and 15% in conductivity can occur that does not otherwise degrade the property recovery accuracy of inclusions that actually exist. The work sets the stage for integrating microwave imaging with MR for improved resolution and functional imaging of the breast in the future.

    In Portugal, the 7-valent pneumococcal conjugate vaccine (PCV7) was not introduced in the national immunization plan but was commercially available between 2001 and 2010. We studied serotype distribution and antibiotic susceptibility of Streptococcus pneumoniae carried by children in 2009 and 2010. Vaccination with PCV7 was extracted from children's immunization bulletins and information on recent antimicrobial consumption was obtained through a questionnaire. For comparison, we included data from previous studies conducted since 1996: 1996-1999, 2001-2003, 2006-2007. Pneumococci were isolated from nasopharyngeal samples of 1092 children up to six years old attending day-care in an urban area. Among these, 76% (819/1070) were vaccinated and 62% (677/1092) carried pneumococci. In 2009-2010, serotype replacement was extensive. Carriage of PCV7 serotypes was 4.9% and 5.8%, in 2009 and 2010, respectively, with the majority being of serotype 19F (carried by 4.3% and 4.6% of all participants, respectively). Colonization by serotype 19F was associated with vaccine status (7.7% (19/248) of non-vaccinees vs. 3.5% (29/818) of PCV7-vaccinees, p=0.010). Carriage of serotype 19A was high in 2009 and 2010 (8.6% of all participants) consistent with values already observed in 2007; carriage of serotype 6A was <1% (10/1092), indicating a major decline after 2007 (5.8% or 31/538, p<0.001). Non-vaccine serotypes increased and serotype 6C became the most frequently carried serotype in 2010 (11.2% (54/481)). High-level resistance to penicillin (MIC ≥2mg/L) showed a decreasing trend (p<0.001), whereas resistance to both penicillin and erythromycin increased (p<0.001) and was detected in 15-20% of all isolates in 2009-2010, most of which were non-vaccine serotypes. Antimicrobial use decreased over time (p<0.001). In conclusion, widespread private use of PCV7 has impacted on colonization leading to near elimination of all PCV7 serotypes except for serotype 19F.

    2012-02-01

    It has been reported that professional baseball players whose first names begin with the letter "D" tend to die relatively young (E. L. Abel & M. L. Kruger, 2010). However, the statistical evidence for this claim is based on selective data and a statistical test that ignores important confounding influences. A valid test applied to more comprehensive data from the same source does not show a statistically significant relationship between initials and longevity. In addition, data for the years 1960 through 2004 for 6.7 million White, non-Hispanic California decedents do not replicate the claim that D's die young. PMID:24567987

    The transformation of wild animals into domestic ones available for human nutrition was a key prerequisite for modern human societies. However, no other domestic species has had such a substantial impact on the warfare, transportation, and communication capabilities of human societies as the horse. Here, we show that the analysis of ancient DNA targeting nuclear genes responsible for coat coloration allows us to shed light on the timing and place of horse domestication. We conclude that it is unlikely that horse domestication substantially predates the occurrence of coat color variation, which was found to begin around the third millennium before the common era.

    Full Text Available This research examined how the professional practice of Canadian beginning elementary teachers was influenced by their own early learning experiences in school. Six teachers were observed and interviewed in their classrooms five times over the first three years of their teaching career. Case studies were developed for each teacher and themes were explored across cases. The findings from this study suggest that pre-service and in-service teacher education programs need to provide teachers with opportunities to critically examine how their relative strengths and weaknesses as pupils may affect their performance and identity as teachers.

  9. How do our prior assumptions about basal drag affect ice sheet forecasts?

    Science.gov (United States)

    Arthern, Robert

    2015-04-01

    Forecasts of changes in the large ice sheets of Greenland and Antarctica often begin with an inversion to select initial values for state variables and parameters in the model, such as basal drag and ice viscosity. These inversions can be ill-posed in the sense that many different choices for the parameter values can match the observational data equally well. To recover a mathematically well-posed problem, assumptions must be made that restrict the possible values of the parameters, either by regularisation or by explicit definition of Bayesian priors. Common assumptions are that parameters vary smoothly in space or lie close to some preferred initial guess, but for glaciological inversions it is often unclear how smoothly the parameters should vary, or how reliable the initial guess should be considered. This is especially true of inversions for the basal drag coefficient that can vary enormously from place to place on length scales set by subglacial hydrology, which is itself extremely poorly constrained by direct observations. Here we use a combination of forward modelling, inversion and a theoretical analysis based on transformation group priors to investigate different ways of introducing prior information about parameters, and to consider the consequences for ice sheet forecasts.

  10. Prior knowledge in recalling arguments in bioethical dilemmas

    Hiemke Katharina Schmidt

    2015-09-01

    Full Text Available Prior knowledge is known to facilitate learning new information. Normally in studies confirming this outcome the relationship between prior knowledge and the topic to be learned is obvious: the information to be acquired is part of the domain or topic to which the prior knowledge belongs. This raises the question as to whether prior knowledge of various domains facilitates recalling information. In this study 79 eleventh-grade students completed a questionnaire on their prior knowledge of seven different domains related to the bioethical dilemma of prenatal diagnostics. The students read a text containing arguments for and arguments against prenatal diagnostics. After one week and again 12 weeks later they were asked to write down all the arguments they remembered. Prior knowledge helped them recall the arguments one week (r = .350 and 12 weeks (r = .316 later. Prior knowledge of three of the seven domains significantly helped them recall the arguments one week later (correlations between r = .194 to r = .394. Partial correlations with interest as a control item revealed that interest did not explain the relationship between prior knowledge and recall. Prior knowledge of different domains jointly supports the recall of arguments related to bioethical topics.

  11. Bayesian estimation of generalized exponential distribution under noninformative priors

    Moala, Fernando Antonio; Achcar, Jorge Alberto; Tomazella, Vera Lúcia Damasceno

    2012-10-01

    The generalized exponential distribution, proposed by Gupta and Kundu (1999), is a good alternative to standard lifetime distributions as exponential, Weibull or gamma. Several authors have considered the problem of Bayesian estimation of the parameters of generalized exponential distribution, assuming independent gamma priors and other informative priors. In this paper, we consider a Bayesian analysis of the generalized exponential distribution by assuming the conventional noninformative prior distributions, as Jeffreys and reference prior, to estimate the parameters. These priors are compared with independent gamma priors for both parameters. The comparison is carried out by examining the frequentist coverage probabilities of Bayesian credible intervals. We shown that maximal data information prior implies in an improper posterior distribution for the parameters of a generalized exponential distribution. It is also shown that the choice of a parameter of interest is very important for the reference prior. The different choices lead to different reference priors in this case. Numerical inference is illustrated for the parameters by considering data set of different sizes and using MCMC (Markov Chain Monte Carlo) methods.

  12. Confidence and Loose Opportunism in the Science Classroom: Towards a pedagogy of investigative science for beginning teachers

    Science.gov (United States)

    McNally, Jim

    2006-03-01

    This paper attempts to establish a conceptual basis on which beginning teachers may be introduced to investigative science teaching in a way that accommodates the teacher voice. It draws mainly on preliminary theory from the shared reflections of 20 science teachers, augmented by a more general interview-based study of the experience of early professional learning of 18 new teachers. Internationally, it is situated in the wider concern in the literature with the nature of science, mainly in initial teacher education. Empirically located within the Scottish context, a grounded epistemological base of teacher knowledge is illustrated and presented as components of confidence in a cycle of professional learning that needs to be set in motion during initial teacher education. It is proposed that, given protected experience in their early attempts to teach investigatively, new teachers can begin to develop a confident pedagogy of loose opportunism that comes close to authentic science for the children they teach.

  19. Chromosomal differences between acute nonlymphocytic leukemia in patients with prior solid tumors and prior hematologic malignancies. A study of 14 cases with prior breast cancer

    International Nuclear Information System (INIS)

    A cytogenetic study of 14 patients with secondary acute nonlymphocytic leukemia (S-ANLL) with prior treatment for breast cancer is reported. The chromosomes recurrently involved in numerical or structural anomalies are chromosomes 7, 5, 17, and 11, in decreasing order of frequency. The distribution of the anomalies detected in this sample of patients is similar to that observed in published cases with prior breast or other solid tumors, though anomalies of chromosome 11 were not pointed out, but it significantly differs from that of the S-ANLL with prior hematologic malignancies. This difference is principally due to a higher involvement of chromosome 7 in patients with prior hematologic malignancies and of chromosomes 11 and 17 in patients with prior solid tumors. A genetic determinism involving abnormal recessive alleles located on chromosomes 5, 7, 11, and 17 uncovered by deletions of the normal homologs may be a cause of S-ANLL. The difference between patients with prior hematologic malignancies or solid tumors may be explained by different constitutional mutations of recessive genes in the two groups of patients

    2015-10-01

    Full Text Available On the one hand, Wittgenstein considers philosophy as a generator of mental confusion, but on the other hand, he desires philosopher as a therapist. This two-sided attitude to philosophy begins with Tractatus and then admitting the various therapeutic methods, reaches to the second period of his life. Recently, the origins of Wittgenstein's therapeutic approach in Tractatus are neglected by most of his positivist commentators, instead, this approach have been followed in the second period of his thought, especially in Philosophical Investigations. In this essay, we have tried to clarify this obscurity and to indicate the roots of Wittgenstein's therapeutic approach in Tractatus. Since mentioning the "symptom" or symptoms of mental confusion resulting from philosophical thinking and stage of its "diagnosis" is considered as preparations of therapy, we, by emphasizing on the therapeutic value of clarity, will survey "symptom", "diagnosis" and finally Wittgenstein's therapeutic approach toward philosophy in Tractatus, and then we will point out some reasons causing negligence to Tractatus therapeutic approach. In this way, we will show that Wittgenstein, from the beginning of his philosophical thinking, has believed in this approach and in Philosophical Investigations he has just declared it in the everyday language. Here, we will also unveil restriction of Wittgenstein's therapeutic approach to philosophy.

  2. Testability evaluation using prior information of multiple sources

    2014-01-01

    Testability plays an important role in improving the readiness and decreasing the life-cycle cost of equipment. Testability demonstration and evaluation is of significance in measuring such testability indexes as fault detection rate (FDR) and fault isolation rate (FIR), which is useful to the producer in mastering the testability level and improving the testability design, and helpful to the consumer in making purchase decisions. Aiming at the problems with a small sample of testabil-ity demonstration test data (TDTD) such as low evaluation confidence and inaccurate result, a test-ability evaluation method is proposed based on the prior information of multiple sources and Bayes theory. Firstly, the types of prior information are analyzed. The maximum entropy method is applied to the prior information with the mean and interval estimate forms on the testability index to obtain the parameters of prior probability density function (PDF), and the empirical Bayesian method is used to get the parameters for the prior information with a success-fail form. Then, a parametrical data consistency check method is used to check the compatibility between all the sources of prior information and TDTD. For the prior information to pass the check, the prior credibility is calculated. A mixed prior distribution is formed based on the prior PDFs and the corresponding credibility. The Bayesian posterior distribution model is acquired with the mixed prior distribution and TDTD, based on which the point and interval estimates are calculated. Finally, examples of a flying control system are used to verify the proposed method. The results show that the proposed method is feasible and effective.

    Full Text Available The surgical management of pediatric stone disease has evolved significantly over the last three decades. Prior to the introduction of shockwave lithotripsy (SWL in the 1980s, open lithotomy was the lone therapy for children with upper tract calculi. Since then, SWL has been the procedure of choice in most pediatric centers for children with large renal calculi. While other therapies such as percutaneous nephrolithotomy (PNL were also being advanced around the same time, PNL was generally seen as a suitable therapy in adults because of the concerns for damage in the developing kidney. However, recent advances in endoscopic instrumentation and renal access techniques have led to an increase in its use in the pediatric population, particularly in those children with large upper tract stones. This paper is a review of the literature focusing on the indications, techniques, results, and complications of PNL in children with renal calculi.

    The underutilized practice of photographing anatomic pathology specimens from surgical pathology and autopsies is an invaluable benefit to patients, clinicians, pathologists, and students. Photographic documentation of clinical specimens is essential for the effective practice of pathology. When considering what specimens to photograph, all grossly evident pathology, absent yet expected pathologic features, and gross-only specimens should be thoroughly documented. Specimen preparation prior to photography includes proper lighting and background, wiping surfaces of blood, removing material such as tubes or bandages, orienting the specimen in a logical fashion, framing the specimen to fill the screen, positioning of probes, and using the right-sized scale.

    2006-05-31

    Efficient analysis of written words in normal reading is likely to reflect use of neural circuits formed by experience during childhood rather than an innate process. We investigated the cortical sequence of word perception in first-graders (7-8 years old), with special emphasis on occipitotemporal cortex in which, in adults, letter-string-sensitive responses are detected at 150 ms after stimulus. To identify neural activation that is sensitive to either the amount of basic visual features or specifically to letter strings, we recorded whole-head magnetoencephalography responses to words embedded in three different levels of noise and to symbol strings. As was shown previously in adults, activation reflecting stimulus nonspecific visual feature analysis was localized to occipital cortex in children. It was followed by letter-string-sensitive activation in the left occipitotemporal cortex and, subsequently, in the temporal cortex. These processing stages were correlated in timing and activation strength. Compared with adults, however, the timing of activation was clearly delayed in children, and the delay was progressively increased from occipital to occipitotemporal and further to temporal areas. This finding is likely to reflect increasing immaturity of the underlying neural generators when advancing from low-level visual analysis to higher-order areas involved in written word perception. When a salient occipitotemporal letter-string-sensitive activation was detected (10 of 18 children), its strength was correlated with phonological skills, in line with the known relevance of phonological awareness in reading acquisition.

  10. Tools for investigating the prior distribution in Bayesian hydrology

    Tang, Yating; Marshall, Lucy; Sharma, Ashish; Smith, Tyler

    2016-07-01

    Bayesian inference is one of the most popular tools for uncertainty analysis in hydrological modeling. While much emphasis has been placed on the selection of appropriate likelihood functions within Bayesian hydrology, few researchers have evaluated the importance of the prior distribution in deriving appropriate posterior distributions. This paper describes tools for the evaluation of parameter sensitivity to the prior distribution to provide guidelines for defining meaningful priors. The tools described here consist of two measurements, the Kullback-Leibler Divergence (KLD) and the prior information elasticity. The Kullback-Leibler Divergence (KLD) is applied to calculate differences between the prior and posterior distributions for different cases. The prior information elasticity is then used to quantify the responsiveness of the KLD values to the change of prior distributions and length of available data. The tools are demonstrated via a Bayesian framework using an MCMC algorithm for a conceptual hydrologic model with both synthetic and real cases. The results of the application of this toolkit suggest the prior distribution can have a significant impact on the posterior distribution and should be more routinely assessed in hydrologic studies.

  1. Construction and test of the PRIOR proton microscope; Aufbau und Test des Protonenmikroskops PRIOR

    Energy Technology Data Exchange (ETDEWEB)

    Lang, Philipp-Michael

    2015-01-15

    The study of High Energy Density Matter (HEDM) in the laboratory makes great demands on the diagnostics because these states can usually only be created for a short time and usual diagnostic techniques with visible light or X-rays come to their limit because of the high density. The high energy proton radiography technique that was developed in the 1990s at the Los Alamos National Laboratory is a very promising possibility to overcome those limits so that one can measure the density of HEDM with high spatial and time resolution. For this purpose the proton microscope PRIOR (Proton Radiography for FAIR) was set up at GSI, which not only reproduces the image, but also magnifies it by a factor of 4.2 and thereby penetrates matter with a density up to 20 g/cm{sup 2}. Straightaway a spatial resolution of less than 30 μm and a time resolution on the nanosecond scale was achieved. This work describes details to the principle, design and construction of the proton microscope as well as first measurements and simulations of essential components like magnetic lenses, a collimator and a scintillator screen. For the latter one it was possible to show that plastic scintillators can be used as converter as an alternative to the slower but more radiation resistant crystals, so that it is possible to reach a time resolution of 10 ns. Moreover the characteristics were investigated for the system at the commissioning in April 2014. Also the changes in the magnetic field due to radiation damage were studied. Besides that an overview about future applications is given. First experiments with Warm Dense Matter created by using a Pulsed Power Setup have already been performed. Furthermore the promising concept of combining proton radiography with particle therapy has been investigated in context of the PaNTERA project. An outlook on the possibilities with future experiments at the FAIR accelerator facility is given as well. Because of higher beam intensity an energy one can expect even

  2. Asymptotic admissibility of priors and elliptic differential equations

    CERN Document Server

    Hartigan, J A

    2010-01-01

    We evaluate priors by the second order asymptotic behavior of the corresponding estimators.Under certain regularity conditions, the risk differences between efficient estimators of parameters taking values in a domain D, an open connected subset of R^d, are asymptotically expressed as elliptic differential forms depending on the asymptotic covariance matrix V. Each efficient estimator has the same asymptotic risk as a 'local Bayes' estimate corresponding to a prior density p. The asymptotic decision theory of the estimators identifies the smooth prior densities as admissible or inadmissible, according to the existence of solutions to certain elliptic differential equations. The prior p is admissible if the quantity pV is sufficiently small near the boundary of D. We exhibit the unique admissible invariant prior for V=I,D=R^d-{0). A detailed example is given for a normal mixture model.

    Prior distributions elicited for modelling the natural fluctuations or the uncertainty on parameters of Bayesian fishery population models, can be chosen among a vast range of statistical laws. Since the statistical framework is defined by observational processes, observational parameters enter into the estimation and must be considered random, similarly to parameters or states of interest like population levels or real catches. The former are thus perceived as nuisance parameters whose values are intrinsically linked to the considered experiment, which also require noninformative priors. In fishery research Jeffreys methodology has been presented by Millar (2002) as a practical way to elicit such priors. However they can present wrong properties in multiparameter contexts. Therefore we suggest to use the elicitation method proposed by Berger and Bernardo to avoid paradoxical results raised by Jeffreys priors. These benchmark priors are derived here in the framework of sequential population analysis.

    Exactly half a century has passed since the launch of the first documented research project (1965 Dendral) on computer-assisted organic synthesis. Many more programs were created in the 1970s and 1980s but the enthusiasm of these pioneering days had largely dissipated by the 2000s, and the challenge of teaching the computer how to plan organic syntheses earned itself the reputation of a "mission impossible". This is quite curious given that, in the meantime, computers have "learned" many other skills that had been considered exclusive domains of human intellect and creativity-for example, machines can nowadays play chess better than human world champions and they can compose classical music pleasant to the human ear. Although there have been no similar feats in organic synthesis, this Review argues that to concede defeat would be premature. Indeed, bringing together the combination of modern computational power and algorithms from graph/network theory, chemical rules (with full stereo- and regiochemistry) coded in appropriate formats, and the elements of quantum mechanics, the machine can finally be "taught" how to plan syntheses of non-trivial organic molecules in a matter of seconds to minutes. The Review begins with an overview of some basic theoretical concepts essential for the big-data analysis of chemical syntheses. It progresses to the problem of optimizing pathways involving known reactions. It culminates with discussion of algorithms that allow for a completely de novo and fully automated design of syntheses leading to relatively complex targets, including those that have not been made before. Of course, there are still things to be improved, but computers are finally becoming relevant and helpful to the practice of organic-synthetic planning. Paraphrasing Churchill's famous words after the Allies' first major victory over the Axis forces in Africa, it is not the end, it is not even the beginning of the end, but it is the end of the beginning for the

  5. Jacopo da Firenze and the Beginning of Italian Vernacular Algebra

    2006-01-01

    In 1307, one Jacobus de Florentia located at that moment in Montpellier wrote a Tractatus algorismi containing a chapter on algebra. This earliest extant algebra in a European vernacular is noteworthy in several respects: 1.For decades, every writing on algebra in Italy or Montpellier which we know...... mediated through a Romance-speaking area. The obvious guess (supported by supplementary evidence) is that this area was Catalonia, even though the Catalan-Provencal tradition is only known to us from considerably later sources. Further inspection of Jacopo's algebra and other slightly later Italian...... writings of enigmatic origin suggest that the earliest beginnings of formal operations (on schemes and on fractions involving cossic expressions) may also have come from the same area....

  6. Sacred Space: A Beginning Framework for Off-Planet Church

    Science.gov (United States)

    Hoffmann, T. K.

    As governments and corporations continue to engage space security, commerce, exploration and colonization, the Christian Church will not be far behind. Historically the Church has always been part of the first waves of explorers and colonizers, with its ideological interests being easily supported by generous resources and strong infrastructures. The exploring Church has not always been a friendly guest, however, and at times has initiated or condoned great harm. This paper offers a beginning framework as one way of insuring an appropriate presence in space for the Church. This framework is built with three common religious planks, namely, theology, ecclesiology and church worker vocation. Each of these is recast in terms of the off-planet scenario. This paper concludes that an appropriate off-planet Church will be founded on an "exomissiological" theology, will embrace an ecclesiology that emphasizes religious health, and will adequately select, train and monitor its off-planet church workers.

    In "Dark Victory," released in theaters in 1939, the diagnosis and management of a progressive brain tumor was a central part of the screenplay, and this film marked the beginnings of the depiction of neurologic disease in cinema. Bette Davis' cinematic portrayal of a young woman dying from a brain tumor is close to the reality of denial, bargaining, a hope for a cure, and final acceptance. "Dark Victory" includes part of a neurologic examination (funduscopy, testing of strength, testing of stereognosis, and tendon reflexes). The film also alludes to decisions on what to tell the patient (better say nothing) and shows an implausible clinical course (an abrupt peaceful ending). The film is unusual in depicting the presentation of a brain tumor, but the cinematic portrayal of the vicissitudes of living with a brain tumor is often close to reality. PMID:27163660

    Full Text Available Onchocerciasis, also known as River Blindness, is a parasitic disease caused by the nematode Onchocerca volvulus and transmitted by black flies of the genus Simulium. It is endemic in Africa, where an estimated 37 million people are infected. It is almost certain that the slave trade in the 17th and 18th centuries brought onchocerciasis from West Africa to the Americas (1,  where transmission foci  where established  in  six  countries: Mexico, Guatemala, Venezuela,  Brazil, Ecuador  and Colombia.  Since the beginning of the 20th century it was suspected that this vector borne disease was present in Colombia but the first confirmed case was not reported until 1965. The exact location of the single focus in the country was confirmed almost thirty years later in the locality of Naicioná, on the stream that bears the same name

    Full Text Available The problem of AIDS had not been recognized up to 1981 and in 1984 it was found that HIV virus is factor of this disease. For the time beings AIDS/HIV infection has chanched to a pandemic and cases affected to it are now reported from all over the world. In our country the first case was reported in 1987. Regarding the importance of disease and recognition of its prevention and transmission routes, based on disease epidemiology in country, this survey was conducted. This study was performed in 1999-2000 and is retrospective descriptive study. The main purpose of study is epidemiology of AIDS in Iran from beginning until now. Total information of cases of AIDS/HIV from beginning in Iran and all performed activities were obtained from ministry of health center for disease control-AIDS Dept. 95 files existing in the archives of Imam Khomeini hospital related to AIDS were also studied. 1953 cases of HIV+ have been reported until March of year 2000. At the same time 250 cases of AIDS have been reported which 215 of them died. Among transmission routes, in AIDS disease the most common way of transmission was transfusion of infected blood or its components but in HIV+ case the most one was drug injection. With respect to age, the higher and lower rate of affected people were in 30-39 and 0-4 ranges years respectively. The sex percentage in AIDS affected and HIV+ persons were 90.8% and 9.2%; 95.2% and 4.8% male and female respectively. 130 from 1953 HIV+ cases had travel to abroad.

    Maintaining social order requires the policing of transgressions. Prior research suggests that policing emerges early in life, but little is known about children's engagement in such behavior in live interactions where there is uncertainty about the consequences. In this study, 4- to 11-year-old children (N=158) witnessed an unfamiliar adult confederate intentionally destroy another adult's property. Of interest was whether children would engage in policing behavior by protesting to the transgressor or by spontaneously reporting the transgression to a third party. Some children engaged in these behaviors spontaneously; nearly half (42%) protested the transgression, and 27% reported it without being prompted. Even when children did not spontaneously report the transgression, they almost always reported it when asked directly. The findings show that children commonly engage in policing even in the face of potentially negative consequences. PMID:27295206

    This article reviews the research literature on links between parental divorce and children's short-term and long-term adjustment. First, I consider evidence regarding how divorce relates to children's externalizing behaviors, internalizing problems, academic achievement, and social relationships. Second, I examine timing of the divorce, demographic characteristics, children's adjustment prior to the divorce, and stigmatization as moderators of the links between divorce and children's adjustment. Third, I examine income, interparental conflict, parenting, and parents well-being as mediators of relations between divorce and children's adjustment. Fourth, I note the caveats and limitations of the research literature. Finally, I consider notable policies related to grounds for divorce, child support, and child custody in light of how they might affect children s adjustment to their parents divorce.

    Segmentation of hippocampus in the brain is one of a major challenge in medical image segmentation due to its' imaging characteristics, with almost similar intensity between another adjacent gray matter structure, such as amygdala. The intensity similarity has causes the hippocampus to have weak or fuzzy boundaries. With this main challenge being demonstrated by hippocampus, a segmentation method that relies on image information alone may not produce accurate segmentation results. Therefore, it is needed an assimilation of prior information such as shape and spatial information into existing segmentation method to produce the expected segmentation. Previous studies has widely integrated prior information into segmentation methods. However, the prior information has been utilized through a global manner integration, and this does not reflect the real scenario during clinical delineation. Therefore, in this paper, a locally integrated prior information into a level set model is presented. This work utilizes a mean shape model to provide automatic initialization for level set evolution, and has been integrated as prior information into the level set model. The local integration of edge based information and prior information has been implemented through an edge weighting map that decides at voxel level which information need to be observed during a level set evolution. The edge weighting map shows which corresponding voxels having sufficient edge information. Experiments shows that the proposed integration of prior information locally into a conventional edge-based level set model, known as geodesic active contour has shown improvement of 9% in averaged Dice coefficient.

  13. Implicit Priors in Galaxy Cluster Mass and Scaling Relation Determinations

    Mantz, A.; Allen, S. W.

    2011-01-01

    Deriving the total masses of galaxy clusters from observations of the intracluster medium (ICM) generally requires some prior information, in addition to the assumptions of hydrostatic equilibrium and spherical symmetry. Often, this information takes the form of particular parametrized functions used to describe the cluster gas density and temperature profiles. In this paper, we investigate the implicit priors on hydrostatic masses that result from this fully parametric approach, and the implications of such priors for scaling relations formed from those masses. We show that the application of such fully parametric models of the ICM naturally imposes a prior on the slopes of the derived scaling relations, favoring the self-similar model, and argue that this prior may be influential in practice. In contrast, this bias does not exist for techniques which adopt an explicit prior on the form of the mass profile but describe the ICM non-parametrically. Constraints on the slope of the cluster mass-temperature relation in the literature show a separation based the approach employed, with the results from fully parametric ICM modeling clustering nearer the self-similar value. Given that a primary goal of scaling relation analyses is to test the self-similar model, the application of methods subject to strong, implicit priors should be avoided. Alternative methods and best practices are discussed.

    Tractography is the standard tool for automatic delineation of white matter tracts from diffusion weighted images. However, the output of tractography often requires post-processing to remove false positives and ensure a robust delineation of the studied tract, and this demands expert prior knowledge. Here we demonstrate how such prior knowledge, or indeed any prior spatial information, can be automatically incorporated into a shortest-path tractography approach to produce more robust results. We describe how such a prior can be automatically generated (learned) from a population, and we demonstrate that our framework also retains support for conventional interactive constraints such as waypoint regions. We apply our approach to the open access, high quality Human Connectome Project data, as well as a dataset acquired on a typical clinical scanner. Our results show that the use of a learned prior substantially increases the overlap of tractography output with a reference atlas on both populations, and this is confirmed by visual inspection. Furthermore, we demonstrate how a prior learned on the high quality dataset significantly increases the overlap with the reference for the more typical yet lower quality data acquired on a clinical scanner. We hope that such automatic incorporation of prior knowledge and the obviation of expert interactive tract delineation on every subject, will improve the feasibility of large clinical tractography studies.

    Problem-solving skills training is an intervention designed to teach coping skills that has shown to decrease negative affectivity (depressive symptoms, negative mood, and post-traumatic stress symptoms) in mothers of children with cancer. The objective of this study was to see whether mothers of children recently diagnosed with autism spectrum disorder would be receptive to receiving problem-solving skills training (feasibility trial). Participants were recruited from a local outpatient developmental clinic that is part of a university department of pediatrics. Participants were to receive eight 1-h sessions of problem-solving skills training and were asked to complete assessments prior to beginning problem-solving skills training (T1), immediately after intervention (T2), and 3 months after T2 (T3). Outcome measures assessed problem-solving skills and negative affectivity (i.e. distress). In total, 30 mothers were approached and 24 agreed to participate (80.0%). Of them, 17 mothers completed problem-solving skills training (retention rate: 70.8%). Mothers of children with autism spectrum disorder who completed problem-solving skills training had significant decreases in negative affectivity and increases in problem-solving skills. A comparison to mothers of children with cancer shows that mothers of children with autism spectrum disorder displayed similar levels of depressive symptoms but less negative mood and fewer symptoms of post-traumatic stress. Data suggest that problem-solving skills training may be an effective way to alleviate distress in mothers of children recently diagnosed with autism spectrum disorder. Data also suggest that mothers of children with autism spectrum disorder were moderately receptive to receiving problem-solving skills training. Implications are that problem-solving skills training may be beneficial to parents of children with autism spectrum disorder; modifications to improve retention rates are suggested. PMID:25896269

    Sparse signal recovery addresses the problem of solving underdetermined linear inverse problems subject to a sparsity constraint. We propose a novel prior formulation, the structured spike and slab prior, which allows to incorporate a priori knowledge of the sparsity pattern by imposing a spatial...... Gaussian process on the spike and slab probabilities. Thus, prior information on the structure of the sparsity pattern can be encoded using generic covariance functions. Furthermore, we provide a Bayesian inference scheme for the proposed model based on the expectation propagation framework. Using...

    2014-12-01

    Drug repurposing (i.e., finding novel indications for established substances) has received increasing attention in industry recently. One challenge of repositioned drugs is obtaining effective patent protection, especially if the 'novel' indications have already been claimed by competitors within the same drug class. Here, I report the case of patents relating to phosphodiesterase type 5 (PDE5) inhibitors. Patentees of later-filed patents on novel indications (even when they could not observe prior patenting of their direct competitors) filed patents for which patent examiners did not see the prior-filed patents of the competitors as relevant prior art, whereas these follower patent applications often failed because of other reasons.

    Demir, Abdulkadir

    The purpose of this phenomenographic study was to: (a) understand how beginning science teachers recruited from various science disciplines and prepared in an Alternative Teacher Certification Program (ATCP) implemented inquiry during their initial years of teaching; (b) describe constraints and needs that these beginning science teachers perceived in implementing inquiry-based science instruction; and (c) understand the relation between what they learned in their ATCP and their practice of teaching science through inquiry. The participants of this study consisted of four ATCP teachers who are in their beginning years of teaching. Semi-structured interviews, classroom observation, field notes, and artifacts used as source of data collection. The beginning science teachers in this study held incomplete views of inquiry. These views of inquiry did not reflect inquiry as described in NRC (2000)---essential features of inquiry,---nor did they reflect views of faculty members involved in teaching science methods courses. Although the participants described themselves as reform-oriented, there were inconsistencies between their views and practices. Their practice of inquiry did not reflect inquiry either as outlined by essential features of inquiry (NRC, 2000) or inquiry as modeled in activities used in their ATCP. The research participants' perceived constraints and needs in their implementation of inquiry-based activities. Their perceived constraints included logistical and student constraints and school culture. The perceived needs included classroom management, pedagogical skills, practical knowledge, discipline, successful grade-specific models of inquiry, and access to a strong support system. Prior professional work experience, models and activities used in the ATCP, and benefits of inquiry to student learning were the declared factors that facilitated the research participants' practice of inquiry-based teaching.

    In most Western countries, clinical management of disorders of sex development (DSD), including ambiguous genitalia, begins at diagnosis soon after birth. For many Indonesian patients born with ambiguous genitalia, limited medical treatment is available. Consequently, affected individuals are raised with ambiguous genitalia and atypical secondary sex characteristics. We investigated gender identity and gender role behavior in 118 Indonesian subjects (77 males, 41 females) with different types of DSD in comparison with 118 healthy controls matched for gender, age, and residential setting (rural, suburban, or urban). In Study 1, we report on methodological aspects of the investigation, including scale adaptation, pilot testing, and determining reliability and validity of measures. In Study 2, we report on gender development in 60 children (42 boys, 18 girls), 24 adolescents (15 boys, 9 girls), and 34 adults (19 men, 15 women) with DSD. The majority of participants with DSD never received any medical or surgical treatment prior to this study. We observed a gender change in all age groups, with the greatest incidence in adults. Among patients who changed, most changed from female to male, possessed a 46,XY karyotype, and had experienced significant masculinization during life. Gender identity confusion and cross-gender behavior was more frequently observed in children with DSD raised as girls compared to boys. Puberty and associated masculinization were related to gender problems in individuals with 46,XY DSD raised female. An integrated clinical and psychological follow-up on gender outcome is necessary prior to puberty and adulthood.

    Full Text Available Objective. We estimated time to initiation, outpatient resource use, and costs of outpatient care during the 6 months prior to ART initiation for HIV-infected pediatric patients in Zambia. Methods. We enrolled 1,102 children who initiated ART at <15 years of age between 2006 and 2011 at 5 study sites. Of these, 832 initiated ART ≤6 months after first presenting to care at the study sites. Data on time in care and resources utilized during the 6 months prior to ART initiation were extracted from patient medical records. Costs were estimated from the provider’s perspective and are reported in 2011 USD. Results. For the patients who initiated ART ≤6 months after presenting to care, median age at presentation to care was 3.9 years; median CD4 percentage was 13%. Median time to ART initiation was 26 days. Patients made, on average, 2.38 clinic visits prior to ART initiation and received 0.81 CD4 tests, 0.74 full blood count tests, and 0.49 blood chemistry tests. The mean cost of pre-ART care was $20 per patient. Conclusions. Zambian pediatric patients initiating ART ≤6 months after presenting to care do so quickly, utilize fewer resources than mandated by national guidelines, and accrue low costs.

  10. A Bayesian Approach for Image Segmentation with Shape Priors

    Energy Technology Data Exchange (ETDEWEB)

    Chang, Hang; Yang, Qing; Parvin, Bahram

    2008-06-20

    Color and texture have been widely used in image segmentation; however, their performance is often hindered by scene ambiguities, overlapping objects, or missingparts. In this paper, we propose an interactive image segmentation approach with shape prior models within a Bayesian framework. Interactive features, through mouse strokes, reduce ambiguities, and the incorporation of shape priors enhances quality of the segmentation where color and/or texture are not solely adequate. The novelties of our approach are in (i) formulating the segmentation problem in a well-de?ned Bayesian framework with multiple shape priors, (ii) ef?ciently estimating parameters of the Bayesian model, and (iii) multi-object segmentation through user-speci?ed priors. We demonstrate the effectiveness of our method on a set of natural and synthetic images.

    Airoldi, Edoardo M; Guindani, Michele; Leisen, Fabrizio

    2010-01-01

    Many popular Bayesian Nonparametric priors can be characterized in terms of exchangeable species sampling sequences. One example is the Dirichlet Process prior, that has been increasingly used for modeling purposes in mixture of DP hierarchical models. However, in some applications, the implied exchangeability assumption may not be considered appropriate. We introduce non exchangeable generalized species sampling priors characterized by a tractable predictive probability function with weights driven by a sequence of independent Beta random variables. We discuss some of the properties that can be useful in applications, and we compare our findings with well-known properties of the DP and the two parameters Poisson-Dirichlet process. We detail on Markov Chain Monte Carlo posterior sampling, and illustrate the behavior of such priors by means of a simulation study and an application to the detection of chromosomal aberrations in breast cancer using array CGH data.

This concept is particularly suited for upcoming/on-going large imaging surveys, in which only several broad-band filters are available and it is hard to break some of the degeneracies in the multi-color space. We construct model templates of galaxies using a stellar population synthesis code and apply Bayesian priors on physical properties such as stellar mass and star formation rate. These priors are a function of redshift and they effectively evolve the templates with time in an observationally motivated way. We demonstrate that the priors help reduce the degeneracy and deliver significantly improved photometric redshifts. Furthermore, we show that a template error function, which corrects for systematic flux errors in the model templates as a function of rest-frame wavelength, delivers further improvements. One great advantage of our technique is that we simultaneously measure redshifts...

  13. Variational segmentation problems using prior knowledge in imaging and vision

    Fundana, Ketut

    This dissertation addresses variational formulation of segmentation problems using prior knowledge. Variational models are among the most successful approaches for solving many Computer Vision and Image Processing problems. The models aim at finding the solution to a given energy functional defined......, prior knowledge is needed to obtain the desired solution. The introduction of shape priors in particular, has proven to be an effective way to segment objects of interests. Firstly, we propose a prior-based variational segmentation model to segment objects of interest in image sequences, that can deal...... pose invariant parameters complicate the optimization of the model. To overcome the common numerical problems associated with the step size of the pose parameters in the discretization of the pose model, we propose a novel gradient procedure for the pose estimation based on the construction...

  14. Region-based active contour with noise and shape priors

    Lecellier, François; Fadili, Jalal; Aubert, Gilles; Revenu, Marinette; Saloux, Eric

    2008-01-01

    In this paper, we propose to combine formally noise and shape priors in region-based active contours. On the one hand, we use the general framework of exponential family as a prior model for noise. On the other hand, translation and scale invariant Legendre moments are considered to incorporate the shape prior (e.g. fidelity to a reference shape). The combination of the two prior terms in the active contour functional yields the final evolution equation whose evolution speed is rigorously derived using shape derivative tools. Experimental results on both synthetic images and real life cardiac echography data clearly demonstrate the robustness to initialization and noise, flexibility and large potential applicability of our segmentation algorithm.

  16. Valid MR imaging predictors of prior knee arthroscopy

    International Nuclear Information System (INIS)

    To determine whether fibrosis of the medial patellar reticulum (MPR), lateral patellar reticulum (LPR), deep medial aspect of Hoffa's fat pad (MDH), or deep lateral aspect of Hoffa's fat pad (LDH) is a valid predictor of prior knee arthroscopy. Institutional review board approval and waiver of informed consent were obtained for this HIPPA-compliant study. Initially, fibrosis of the MPR, LPR, MDH, or LDH in MR imaging studies of 50 patients with prior knee arthroscopy and 100 patients without was recorded. Subsequently, two additional radiologists, blinded to clinical data, retrospectively and independently recorded the presence of fibrosis of the MPR in 50 patients with prior knee arthroscopy and 50 without. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for detecting the presence of fibrosis in the MPR were calculated. κ statistics were used to analyze inter-observer agreement. Fibrosis of each of the regions examined during the first portion of the study showed a significant association with prior knee arthroscopy (p < 0.005 for each). A patient with fibrosis of the MPR, LDH, or LPR was 45.5, 9, or 3.7 times more likely, respectively, to have had a prior knee arthroscopy. Logistic regression analysis indicated that fibrosis of the MPR supplanted the diagnostic utility of identifying fibrosis of the LPR, LDH, or MDH, or combinations of these (p ≥ 0.09 for all combinations). In the second portion of the study, fibrosis of the MPR demonstrated a mean sensitivity of 82%, specificity of 72%, PPV of 75%, NPV of 81%, and accuracy of 77% for predicting prior knee arthroscopy. Analysis of MR images can be used to determine if a patient has had prior knee arthroscopy by identifying fibrosis of the MPR, LPR, MDH, or LDH. Fibrosis of the MPR was the strongest predictor of prior knee arthroscopy. (orig.)

    Patent prior-art search is concerned with finding all filed patents relevant to a given patent application. We report a comparison between two search approaches representing the state-of-the-art in patent prior-art search. The first approach uses simple and straightforward information retrieval (IR) techniques, while the second uses much more sophisticated techniques which try to model the steps taken by a patent examiner in patent search. Experiments show that the retrieval effectiveness us...

  19. Implicit Priors in Galaxy Cluster Mass and Scaling Relation Determinations

    2011-01-01

    Deriving the total masses of galaxy clusters from observations of the intracluster medium (ICM) generally requires some prior information, in addition to the assumptions of hydrostatic equilibrium and spherical symmetry. Often, this information takes the form of particular parametrized functions used to describe the cluster gas density and temperature profiles. In this paper, we investigate the implicit priors on hydrostatic masses that result from this fully parametric approach, and the impl...

    We investigate posterior consistency in linear models with a diverging number of parameters. We first propose a parameter-free multivariate generalized double Pareto distribution as a default prior choice that preserves some of the desired characteristics of a joint double exponential distribution with multivariate Cauchy-like tails. We give sufficient conditions for consistency when $p/n\\rightarrow 0$ and then investigate the behavior of the posterior under normal, double exponential and multivariate generalized double Pareto priors.

  2. A well-started beginning elementary teacher's beliefs and practices in relation to reform recommendations about inquiry-based science

    2016-03-01

    Given reform recommendations emphasizing scientific inquiry and empirical evidence pointing to the difficulties beginning teachers face in enacting inquiry-based science, this study explores a well-started beginning elementary teacher's (Sofia) beliefs about inquiry-based science and related instructional practices. In order to explore Sofia's beliefs and instructional practices, several kinds of data were collected in a period of 9 months: a self-portrait and an accompanying narrative, a personal philosophy assignment, three interviews, three journal entries, ten lesson plans, and ten videotaped classroom observations. The analysis of these data showed that Sofia's beliefs and instructional practices were reform-minded. She articulated contemporary beliefs about scientific inquiry and how children learn science and was able to translate these beliefs into practice. Central to Sofia's beliefs about science teaching were scientific inquiry and engaging students in investigations with authentic data, with a prevalent emphasis on the role of evidence in the construction of scientific claims. These findings are important to research aiming at supporting teachers, especially beginning ones, to embrace reform recommendations.

  3. Where to Begin? Eye-Movement When Drawing

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available For over a century, drawing from observation, at least at the introductory level, has been integral to many secondary and most post-secondary art school programs in Europe and North America. Its place in such programs is understood to develop an ability to see and interpret on a flat surface the real, three-dimensional world; this skill, in turn, provides support to related mental processes such as memory, visualization, and imagination. Where an artist looks when drawing from observation may not be arbitrary and can be observed, quantified, and analyzed. Our interest in examining the first few minutes of the drawing process takes its lead from the novice’s question, "Where should I begin?" Attempting to understand these first few minutes led to a collaborative study between art educators and cognitive-perceptual psychologists: the former interested in implications for practical pedagogy, the latter in applying expertise in eye movement and scientific methodology in service of a specific real-world question. The stated purpose of the study notwithstanding, contrasting histories and practices in art and science provided contexts for discussion beyond the collection and interpretation of data. This article seeks to report upon and further that discussion.

  4. [William Harvey and the beginnings of modern medical science].

    2005-01-01

    Modern medical science was born in the post-Renaissance age and began to consolidate towards the middle of the XVII century thanks to physicists, physiologists, and biologists, most of whom were direct or indirect pupils, of Galilei. The discovery of blood circulation by Harvey is now considered the only progress in physiology at the beginning of the XVII century, comparable to the current advances seen in physical sciences. The history of this achievement could be written from the view point of the progressive advance in knowledge. In his experiments, Harvey referred to the authentic, not the imaginary experiments, and put forward irrefutable quantitative arguments. We can therefore claim that his discovery of blood circulation was the first proper explanation of an organic process and the starting point leading to experimental physiology. Nevertheless, the second monograph of the English researcher, dealing with the generation of animals, published in 1651, has some passages that correspond to modern scientific reasoning yet in others he includes confused, vague and capricious assertions compatible with the prescientific era that the author was not able to escape completely. In conclusion, it seems justified to assert that modern medical science did not all rise suddenly, but was gradually structured starting from the middle of the XVII century following the path traced by William Harvey in light of Galilei's thought.

    The first of the 16 cells of SESAME (link is external)’s storage ring was installed recently in the shielding tunnel in the Centre’s experimental hall in Allan, Jordan. SESAME will be the Middle East’s first synchrotron light source. The installation was led by SESAME’s Technical Director, Erhard Huttel, with help from members of CERN forming part of the CESSAMag (CERN-EC Support for SESAME Magnets) team as well as scientists and technicians from the SESAME region. Each cell consists of magnets (dipole, quadrupoles and sextupoles) and the vacuum chamber, supported by a girder. After many years in the making, commissioning of SESAME is scheduled to begin in 2016, serving a growing community of some 300 scientists from the region. The initial research programme will cover topics as diverse as the search for new cancer drugs to the exploration of the regions shared cultural heritage. SESAME is also a pioneer in promoting international cooperation in the region. The laboratory is expected

  6. The Title IV allowance trading program begins to take shape

    International Nuclear Information System (INIS)

    In enacting sweeping amendments to the Clean Air Act in 1990, Congress included provisions for massive reductions of nationwide emissions of sulfur dioxide (SO2) from the electric utility industry. These provisions, commonly referred to as the acid rain program, are set forth in Title IV of both the Amendments and the Act. The 'centerpiece' of the acid rain program is 'an innovative, market-based approach' for bringing about mandated SO2 reductions, which will be embodied in a trading system of fully marketable emission allowances. This paper examines the allowance trading system as it begins to take shape in the latter part of 1991. The statutory commands of Sections 403 (the allowance program) and 416 (reserves, auctions, sales, and guarantees) of the Clean Air Act are reviewed first. There follows a discussion of the important details of the allowance trading program which Congress left for EPA to define in the Part 73 rules, and the principal features of proposed auction and direct sale rules and draft proposed allowance trading rules. At the conclusion is a discussion of several significant questions that remain concerning the development, implementation, and ultimate viability of the allowance trading system

    The story of man's attempt to discover the moment that time began, from James Ussher's confident assertion in 1650 that the world was 5654 years old to the Hubble Space telescope's images of a world 13 billion years old, with a starry cast of eccentrics, mystics, scientists and visonaries. The moment of the beginning of time is one of science's Holy Grails, pursued by devotees and obsessives across the ages. Few were more committed than Bishop James Ussher who lost his sight in his 50-year quest, laboriously outlined in his 2000 Latin pages of Annals - a chronology of all known history - that is now famous only for one spectacularly inaccurate date: 4004BC, the creation of the world. Theology failed Ussher, just as it thwarted Theophilus of Antioch and many others before him. Geology was next to fail the test of time: the Comte de Buffon, working out the rate at which the Earth was supposed to have cooled, came up with age of 74,832 years, even though he suspected this was far too little.

    2016-05-01

    A defining period in the history of civilization occurred in ancient Mesopotamia. While some of Mesopotamian contributions to knowledge (writing, mathematics, astronomy) have been recognized, those made to medicine are just beginning to be studied and appreciated. The medicine of the time developed in a theocratic society where local gods controlled all aspects of life and their healers were learned scribes who established the priestly medicine of old. For their use of prayers and incantations as a component of therapy Mesopotamian medicine has been belittled and relegated to magic. In fact, the Mesopotamian healers established the basic medical skills of observation, diagnosis, prognosis and treatment and, over time, systematically produced an expanding corpus of medical knowledge that had not existed theretofore. The kidney as an organ, the components of the urogenital tract, some signs and symptoms of renal diseases, and the art of urinalysis were first conceptualized, studied, and codified in Mesopotamia. In doing so, the Mesopotamians set the foundations of rational medicine that would follow after the introduction of the phonetic alphabet and the Socratic method of questioning and debate to stimulate critical analysis.

    Full Text Available Interval temporal logics (ITLs are logics for reasoning about temporal statements expressed over intervals, i.e., periods of time. The most famous ITL studied so far is Halpern and Shoham's HS, which is the logic of the thirteen Allen's interval relations. Unfortunately, HS and most of its fragments have an undecidable satisfiability problem. This discouraged the research in this area until recently, when a number non-trivial decidable ITLs have been discovered. This paper is a contribution towards the complete classification of all different fragments of HS. We consider different combinations of the interval relations Begins, After, Later and their inverses Abar, Bbar, and Lbar. We know from previous works that the combination ABBbarAbar is decidable only when finite domains are considered (and undecidable elsewhere, and that ABBbar is decidable over the natural numbers. We extend these results by showing that decidability of ABBar can be further extended to capture the language ABBbarLbar, which lays in between ABBar and ABBbarAbar, and that turns out to be maximal w.r.t decidability over strongly discrete linear orders (e.g. finite orders, the naturals, the integers. We also prove that the proposed decision procedure is optimal with respect to the complexity class.

    Full Text Available In order to conduct the prior disciplinary investigation, the employee shall be convoked in writing by the person authorized by the employer to carry out the research, specifying the subject, date, time and place of the meeting. For this purpose the employer shall appoint a committee charged with conducting the prior disciplinary investigation. Prior disciplinary research cannot be done without the possibility of the accused person to defend himself. It would be an abuse of the employer to violate these provisions. Since the employee is entitled to formulate and sustain defence in proving innocence or lesser degree of guilt than imputed, it needs between the moment were disclosed to the employee and the one of performing the prior disciplinary investigation to be a reasonable term for the employee to be able to prepare a defence in this regard. The employee's failure to present at the convocation, without an objective reason entitles the employer to dispose the sanctioning without making the prior disciplinary investigation. The objective reason which makes the employee, that is subject to prior disciplinary investigation, unable to present to the preliminary disciplinary investigation, should be at the time of the investigation in question.

  12. A Structure Learning Algorithm for Bayesian Network Using Prior Knowledge

    2015-01-01

    Learning structure from data is one of the most important fundamental tasks of Bayesian network research. Particularly, learning optional structure of Bayesian network is a non-deterministic polynomial-time (NP) hard problem. To solve this problem, many heuristic algorithms have been proposed, and some of them learn Bayesian network structure with the help of different types of prior knowledge. However, the existing algorithms have some restrictions on the prior knowledge, such as quality restriction and use restriction. This makes it difficult to use the prior knowledge well in these algorithms. In this paper, we introduce the prior knowledge into the Markov chain Monte Carlo (MCMC) algorithm and propose an algorithm called Constrained MCMC (C-MCMC) algorithm to learn the structure of the Bayesian network. Three types of prior knowledge are defined: existence of parent node, absence of parent node, and distribution knowledge including the conditional probability distribution (CPD) of edges and the probability distribution (PD) of nodes. All of these types of prior knowledge are easily used in this algorithm. We conduct extensive experiments to demonstrate the feasibility and effectiveness of the proposed method C-MCMC.

  13. Genetic diversity of circulating rotavirus strains in Tanzania prior to the introduction of vaccination.

    Full Text Available BACKGROUND: Tanzania currently rolls out vaccination against rotavirus-diarrhea, a major cause of child illness and death. As the vaccine covers a limited number of rotavirus variants, this study describes the molecular epidemiology of rotavirus among children under two years in Dar es Salaam, Tanzania, prior to implementation of vaccination. METHODS: Stool specimens, demographic and clinical information, were collected from 690 children admitted to hospital due to diarrhea (cases and 545 children without diarrhea (controls during one year. Controls were inpatient or children attending child health clinics. Rotavirus antigen was detected using ELISA and positive samples were typed by multiplex semi-nested PCR and sequencing. RESULTS: The prevalence of rotavirus was higher in cases (32.5% than in controls (7.7%, P<0.001. The most common G genotypes were G1 followed by G8, G12, and G4 in cases and G1, G12 and G8 in controls. The Tanzanian G1 variants displayed 94% similarity with the Rotarix vaccine G1 variant. The commonest P genotypes were P[8], P[4] and P[6], and the commonest G/P combination G1 P[8] (n = 123, G8 P[4] and G12 P[6]. Overall, rotavirus prevalence was higher in cool (23.9% than hot months (17.1% of the year (P = 0.012. We also observed significant seasonal variation of G genotypes. Rotavirus was most frequently found in the age group of four to six months. The prevalence of rotavirus in cases was lower in stunted children (28.9% than in non-stunted children (40.1%, P = 0.003 and lower in HIV-infected (15.4%, 4/26 than in HIV-uninfected children (55.3%, 42/76, P<0.001. CONCLUSION: This pre-vaccination study shows predominance of genotype G1 in Tanzania, which is phylogenetically distantly related to the vaccine strains. We confirm the emergence of genotype G8 and G12. Rotavirus infection and circulating genotypes showed seasonal variation. This study also suggests that rotavirus may not be an opportunistic pathogen in

  14. Rhythmic Influence of Top-Down Perceptual Priors in the Phase of Prestimulus Occipital Alpha Oscillations.

    Prior expectations have a powerful influence on perception, biasing both decision and confidence. However, how this occurs at the neural level remains unclear. It has been suggested that spontaneous alpha-band neural oscillations represent rhythms of the perceptual system that periodically modulate perceptual judgments. We hypothesized that these oscillations instantiate the effects of expectations. While collecting scalp EEG, participants performed a detection task that orthogonally manipulated perceptual expectations and attention. Trial-by-trial retrospective confidence judgments were also collected. Results showed that, independent of attention, prestimulus occipital alpha phase predicted the weighting of expectations on yes/no decisions. Moreover, phase predicted the influence of expectations on confidence. Thus, expectations periodically bias objective and subjective perceptual decision-making together before stimulus onset. Our results suggest that alpha-band neural oscillations periodically transmit prior evidence to visual cortex, changing the baseline from which evidence accumulation begins. In turn, our results inform accounts of how expectations shape early visual processing. PMID:27082046

    Full Text Available Introduction. Intravenous administration of recombinant tissue plasminogen activator, fastest and widely feasible treatment in acute ischemic stroke induces arterial recanalization, a prerequisite for neurological recovery. The Therapeutic Role of Ultrasound and Potential Mechanism of Sonothrombolysis. Augmentation of recanalization can be achieved safely in combination with diagnostic transcranial Doppler by delivering mechanical pressure waves to the thrombus and exposing more thrombus surface to circulating drug. The addition of microspheres can further improve thrombolytic effect. Clinical Trials. International multicenter CLOTBUST trial showed that acute ischemic stroke patients treated with sonothrombolysis had higher rate of arterial recanalization and dramatic clinical recovery without increasing risk of symptomatic intracranial hemorrhage. A microsphere dose-escalation study called TUCSON showed that rates of recanalization and clinical recovery tended to be higher in target groups compared with controls. Meta-analysis of clinical trials of sonothrombolysis. Cochrane Stroke Group found that sonothrombolysis was likely to reduce death or dependency. A metaanalysis of sonothrombolysis showed that patients who received any form of sonothrombolysis had more than twofold higher likelihood of achieving complete arterial recanalization. Perspectives for sonothrombolysis - Operator-independent device for sonothrombolysis. The collaborative group of the CLOTBUST trial designed multi-transducer assembly to cover conventional windows used for transcranial Doppler examinations. Operatorindependent device can be quickly mounted by medical personnel with no prior experience in ultrasound. Sonothrombolysis for acute ischemic stroke is now tested in a pivotal efficacy multi-national trial called CLOTBUSTER. Conclusion. Ultrasound is a promising tool to enhance systemic thrombolysis.

    Motivational interviewing (MI) is a promising treatment for heavy drinking. Client change talk (CT), a critical component of MI, has been associated with differential brain activation. The goal of this study was to begin to deconstruct how and why CT may affect the brain. Specifically, we sought to determine whether simply repeating statements in favor of change would cause differential brain activation, or whether client statements must be spontaneously generated within a therapeutic milieu in order to influence brain activation. We therefore examined blood oxygenation level dependent (BOLD) response following two types of client language (CT; and sustain talk, ST) across two conditions: (1) Self-Generated: CT and ST were elicited during an MI session vs. (2) Experimenter-Selected: a pre-established list of CT and ST was provided to the individual in the absence of an MI session. Across both conditions, participants' CT and ST were visually and aurally presented during fMRI. We enrolled 39 recent binge drinkers (41% male; M age=19.9; n=18 in Self-Generated group; n=21 in Experimenter-Selected group). We found that both types of client language (CT and ST) elicited greater BOLD activation in the Self-Generated vs. the Experimenter-Selected group in the left inferior frontal gyrus/anterior insula and superior temporal gyri (p≤0.001). These findings indicate that the nature of client language matters. It appears that it is not just the words themselves, but the origin (naturally generated within a therapeutic session) that influences brain-based effects.

  17. Integrating Environmental Education With Beginning Reading and Phonics Instruction

    Bolsem, Anne M.

    The practice of integrating methods of instruction shows signs of promise as teachers seek new ways to raise student achievement. Although researchers have focused on the efficacy of environment-based education, little research has been done to investigate a framework for integration. The research question that guided this case study was designed to explore the instructional practices teachers employ to integrate environmental education with beginning reading and phonics instruction. The conceptual framework is based on the seminal idea of using the environment as an integrating context, which postulates that the natural world becomes the overarching theme for teaching and learning. Data were obtained through interviews and lesson observations using a purposeful sample of 4 kindergarten and first grade teacher participants. A focus group interview also included the on-site naturalist. Inductive data analysis was used to discover categories and themes. Findings indicated that teachers integrate instruction primarily in the areas of vocabulary and writing after purposeful planning, collaboration, and a deep understanding of broader student goals. Findings also specified that teachers' integration strategies represent a combination of who the teachers are, what they believe, and what action they take in the classroom. Site-specific recommendations for action include ongoing professional development for teachers and support staff, time for collaboration, and review of teacher personal beliefs. Implications for social change include reflection and improvement of practice by teachers at the study site, as well as continued evaluation and discussion about teaching practices and teacher roles leading to more cohesive, enriching integrated instruction rooted in authentic, place-based experiences.

  18. Beginning science teachers' strategies for communicating with families

    Science.gov (United States)

    Bloom, Nena E.

    Science learning occurs in both formal and informal spaces. Families are critical for developing student learning and interest in science because they provide important sources of knowledge, support and motivation. Bidirectional communication between teachers and families can be used to build relationships between homes and schools, leverage family knowledge of and support for learners, and create successful environments for science learning that will support both teaching and student learning. To identify the communication strategies of beginning science teachers, who are still developing their teaching practices, a multiple case study was conducted with seven first year secondary science teachers. The methods these teachers used to communicate with families, the information that was communicated and shared, and factors that shaped these teachers' continued development of communication strategies were examined. Demographic data, interview data, observations and documentation of communication through logs and artifacts were collected for this study. Results indicated that the methods teachers had access to and used for communication impacted the frequency and efficacy of their communication. Teachers and families communicated about a number of important topics, but some topics that could improve learning experiences and science futures for their students were rarely discussed, such as advancement in science, student learning in science and family knowledge. Findings showed that these early career teachers were continuing to learn about their communities and to develop their communication strategies with families. Teachers' familiarity with their school community, opportunities to practice strategies during preservice preparation and student teaching, their teaching environment, school policies, and learning from families and students in their school culture continued to shape and influence their views and communication strategies.

  19. Semiotics of making: beginnings of a theoretical frame

    Full Text Available The contemporary problem of semiotics in architecture is an inherited struggle, not a chosen one. We consider the question of architectural communication because we inevitably recognize its centrality to the problem ofarchitecture itself. While the twentieth-century impact of Saussure and his birthing of structuralism gave architecture a new ground from which to reconceive its own semiotic functions, it was probably never possible that such a synchronic and undialogic theory would suit such a disparate and intersubjective activity. This is not to say that semiotics offers no guidance for the problem of architecture. It may say, however, that to use semiotics productively is not to start from its constructs but instead from architecture’s own.To that end, this study intends to establish a conceptualbasis for communication and meaning in architectural form by an inquiry into making. The initial judgment about why making might prove to be more useful than otherarchitectural characteristics is due to is its essential dialogicnature; it already is a semiotic. In that sense what follows is an opportunistic examination. It arises from what should be considered a powerful—if somewhat neglected—text on making: Elaine Scarry’s 1985 The Body in Pain. A deeper consideration of this work is long overdue. While Scarry’sbook seems to enjoy a rather wide readership, its potential impact has been largely unrealized since few scholars have developed its implications. Given the extraordinary originality of its argument, the artful construction of its prose, and the complex sophistication of its logic, it offers a rich—albeit demanding—place from which to begin.The objective of this study is to schematize Scarry’s theory of making such that connections to a semiotic understanding of its potentials may be realized. Following this effort, a short examination of one particular semiotic aspect of making will be argued as a tentative ground from which to

    Full Text Available The best recognized intestinal manifestation of food allergy is food allergic (food-sensitive enteropathy. The feature of enteropathy may include lymphocyte and plasma cell infiltration, epithelial abnormality, or crypt hyperplastic villous atrophy, and impairing absorption, enterophaty continues while the food remains in the diet, remitting on an exclusion diet, and usually recurring on food challenge. Diagnosis is now usually based on histological features at initial biopsy and clinical response to antigen exclusion and challenge. Clinical findings in food allergic enteropathy include abdominal distension, loose stools, micronutrient deficiency, and rarely protein-losing enteropathy. There may be other features of allergic disease, most commonly eczema unlike coeliac disease, food allergic enteropathies are usually transient in early life, and later challenge is usually tolerated. Cow’s milk-sensitive enteropathy (CMSE was the first recognized food allergic enteropathy and remains the most common cause. The best-characterized syndrome is CMSE, classically presenting with chronic loose stools and failure to thrive, often beginning after an episode of gastroenteritis in a formula-fed infant. Other clinical features include abdominal distension, perianal erythema or napkin rash (due to malabsorbed dietary carbohydrates, and deratographia. Associated clinical features may include colic, gastroesophageal reflux, rectal bleeding, or eczema. There may be evidence of micronutrient deficiency, notably for iron and zinc. Up to 40% of infants with classic CMSE also sensitize to soy, often after an initial period when it is tolerated. The great majority however settle on extensively hydrolyzed formulate. Classic CMSE is usually self-limiting, with most children tolerating reintroduction at the age of 2 to 3 years. By contrast, some children may have persistent low-grade symptoms for a prolonged period. A proportion of children manifest additional

  2. Tilt prior to explosions and the effect of topography on ultra-long-period seismic records at Fuego volcano, Guatemala

    Ground tilt is measured from broadband seismic records prior to frequent explosions at Fuego volcano, Guatemala. We are able to resolve tilt beginning 20-30 minutes prior to explosions, followed by a rapid reversal in deformation coincident with explosion onsets. The tilt amplitude and polarity recorded on the horizontal channels vary from station to station such that the steep and unusual topography of the upper cone of Fuego appears to affect the ultra-long-period signals. We account for the effect of topography and attempt to constrain the tilt source depth and geometry through finite-difference modeling. The results indicate a shallow spherical pressure source, and that topography must be considered when attempting to model tilt sources at volcanoes with steep topography. The tilt signals are interpreted as pressurization of the shallow conduit beneath a crystallized plug followed by elastic deflation concurrent with explosive pressure release.

  3. MAGI-1 modulates AMPA receptor synaptic localization and behavioral plasticity in response to prior experience.

    Directory of Open Access Journals (Sweden)

    Lesley Emtage

    Full Text Available It is well established that the efficacy of synaptic connections can be rapidly modified by neural activity, yet how the environment and prior experience modulate such synaptic and behavioral plasticity is only beginning to be understood. Here we show in C. elegans that the broadly conserved scaffolding molecule MAGI-1 is required for the plasticity observed in a glutamatergic circuit. This mechanosensory circuit mediates reversals in locomotion in response to touch stimulation, and the AMPA-type receptor (AMPAR subunits GLR-1 and GLR-2, which are required for reversal behavior, are localized to ventral cord synapses in this circuit. We find that animals modulate GLR-1 and GLR-2 localization in response to prior mechanosensory stimulation; a specific isoform of MAGI-1 (MAGI-1L is critical for this modulation. We show that MAGI-1L interacts with AMPARs through the intracellular domain of the GLR-2 subunit, which is required for the modulation of AMPAR synaptic localization by mechanical stimulation. In addition, mutations that prevent the ubiquitination of GLR-1 prevent the decrease in AMPAR localization observed in previously stimulated magi-1 mutants. Finally, we find that previously-stimulated animals later habituate to subsequent mechanostimulation more rapidly compared to animals initially reared without mechanical stimulation; MAGI-1L, GLR-1, and GLR-2 are required for this change in habituation kinetics. Our findings demonstrate that prior experience can cause long-term alterations in both behavioral plasticity and AMPAR localization at synapses in an intact animal, and indicate a new, direct role for MAGI/S-SCAM proteins in modulating AMPAR localization and function in the wake of variable sensory experience.

    An audit project was designed to assess and improve the provision of postoperative analgesia in a children's hospital. Pain assessment for all children and analgesia standards for our institution were introduced prior to data collection. Data were collected on consecutive samples of 316 and 325 children undergoing surgery as inpatients during 10-week periods. Change was initiated between the two periods in response to our findings; our action plan involved education, changes to documentation, the widespread use of diclofenac in children over 2 years of age and recommendations for the prescription of analgesia. The initial prescription of analgesia increased from 95% to 98% (p = 0.019), administration of analgesia to children experiencing bad or severe pain increased from 57% to 71% (p = 0.032) and the number of children experiencing severe pain reduced from 17% to 11% (p = 0.050). Application of audit, by a clinical nurse specialist, enabled us to achieve and demonstrate improvements in the prescription, administration and effectiveness of postoperative analgesia.

    2016-01-01

    This paper presents a novel Inverse Synthetic Aperture Radar Imaging (ISAR) algorithm based on a new sparse prior, known as the logarithmic Laplacian prior. The newly proposed logarithmic Laplacian prior has a narrower main lobe with higher tail values than the Laplacian prior, which helps to achieve performance improvement on sparse representation. The logarithmic Laplacian prior is used for ISAR imaging within the Bayesian framework to achieve better focused radar image. In the proposed method of ISAR imaging, the phase errors are jointly estimated based on the minimum entropy criterion to accomplish autofocusing. The maximum a posterior (MAP) estimation and the maximum likelihood estimation (MLE) are utilized to estimate the model parameters to avoid manually tuning process. Additionally, the fast Fourier Transform (FFT) and Hadamard product are used to minimize the required computational efficiency. Experimental results based on both simulated and measured data validate that the proposed algorithm outperforms the traditional sparse ISAR imaging algorithms in terms of resolution improvement and noise suppression.

    Full Text Available The article deals about the results of a study of school-based Assessment of Prior Learning of adults who have enrolled as students in a VET college in order to qualify for occupations as skilled workers. Based on examples of VET teachers’ methods for assessing the students’ prior learning in the programs for gastronomes, respectively child care assistants the article discusses two issues in relation to Assessment of Prior Learing: the encounter of practical experience and school-based knowledge and the validity and reliability of the assessment procedures. Through focusing on the students’ knowing that and knowing why the assessment is based on a scholastic perception of the students’ needs for training, reflecting one of the most important challenges in Assessment of Prior Learning: how can practical experience be transformed into credits for the knowledge parts of the programs? The study shows that by combining several Assessment of Prior Learning methods and comparing the teachers’ assessments the teachers respond to the issues of validity and reliability. However, validity and reliability might be even further strengthened, if the competencies are well defined, if the education system is aware of securing a reasonable balance between knowing how, knowing that, and knowing why, and if the teachers are adequately trained for the assessment procedures.

    In most large-scale real-world pattern classification problems, there is always some explicit information besides given training data, namely prior knowledge, with which the training data are organized. In this paper, we proposed a framework for incorporating this kind of prior knowledge into the training of min-max modular (M3) classifier to improve learning performance. In order to evaluate the proposed method, we perform experiments on a large-scale Japanese patent classification problem and consider two kinds of prior knowledge included in patent documents: patent's publishing date and the hierarchical structure of patent classification system. In the experiments, traditional support vector machine (SVM) and Ma-SVM without prior knowledge are adopted as baseline classifiers. Experimental results demonstrate that the proposed method is superior to the baseline classifiers in terms of training cost and generalization accuracy. Moreover, Ma-SVM with prior knowledge is found to be much more robust than traditional support vector machine to noisy dated patent samples, which is crucial for incremental learning.

    Identification of missing persons from mass disasters is based on evaluation of a number of variables and observations regarding the combination of features derived from these variables. DNA typing now is playing a more prominent role in the identification of human remains, and particularly so for highly decomposed and fragmented remains. The strength of genetic associations, by either direct or kinship analyses, is often quantified by calculating a likelihood ratio. The likelihood ratio can be multiplied by prior odds based on nongenetic evidence to calculate the posterior odds, that is, by applying Bayes' Theorem, to arrive at a probability of identity. For the identification of human remains, the path creating the set and intersection of variables that contribute to the prior odds needs to be appreciated and well defined. Other than considering the total number of missing persons, the forensic DNA community has been silent on specifying the elements of prior odds computations. The variables include the number of missing individuals, eyewitness accounts, anthropological features, demographics and other identifying characteristics. The assumptions, supporting data and reasoning that are used to establish a prior probability that will be combined with the genetic data need to be considered and justified. Otherwise, data may be unintentionally or intentionally manipulated to achieve a probability of identity that cannot be supported and can thus misrepresent the uncertainty with associations. The forensic DNA community needs to develop guidelines for objectively computing prior odds.

    To minimize the number of solutions in 3D resistivity inversion, an inherent problem in inversion, the amount of data considered have to be large and prior constraints need to be applied. Geological and geophysical data regarding the extent of a geological anomaly are important prior information. We propose the use of shape constraints in 3D electrical resistivity inversion. Three weighted orthogonal vectors (a normal and two tangent vectors) were used to control the resistivity differences at the boundaries of the anomaly. The spatial shape of the anomaly and the constraints on the boundaries of the anomaly are thus established. We incorporated the spatial shape constraints in the objective function of the 3D resistivity inversion and constructed the 3D resistivity inversion equation with spatial shape constraints. Subsequently, we used numerical modeling based on prior spatial shape data to constrain the direction vectors and weights of the 3D resistivity inversion. We established a reasonable range between the direction vectors and weights, and verified the feasibility and effectiveness of using spatial shape prior constraints in reducing excessive structures and the number of solutions. We applied the prior spatially shape-constrained inversion method to locate the aquifer at the Guangzhou subway. The spatial shape constraints were taken from ground penetrating radar data. The inversion results for the location and shape of the aquifer agree well with drilling data, and the number of inversion solutions is significantly reduced.

    To assess the effects of an Integrated Care System (ICS) on parent-reported quality of care and satisfaction for Children with Special Health Care Needs (CSHCN). In 2006 Florida reformed its Medicaid program in Broward and Duval counties. Children's Medical Services Network (CMSN) chose to participate in the reform and developed an ICS for CSHCN. The ICS ushered in several changes such as more prior approval requirements and closing of the provider network. Telephone surveys were conducted with CMSN parents whose children reside in the reform counties and parents whose children reside outside of the reform counties in 2006 and 2007 (n = 1,727). Results from multivariate quasi-experimental models show that one component of parent-report quality of care, customer service, increased. Following implementation of the ICS, customer service increased by 0.22 points. After implementation of the ICS, parent-reported quality and satisfaction were generally unaffected. Although significant increases were not seen in the majority of the quality and satisfaction domains, it is nonetheless encouraging that parents did not report negative experiences with the ICS. It is important to present these interim findings so that progress can be monitored and decision-makers can begin to consider if the program should be expanded statewide. PMID:21509433

    The Gardar Province in southern Greenland is a long-lived, rift-related igneous province comprising a suite of basaltic flows, alkaline complexes and dikes. The Gardar period is known to last more than 200 Ma from c. 1350 Ma to 1140 Ma, but is characterized by two main phases of igneous activity represented by early (1300 - 1250 Ma) and late (1180 - 1140 Ma) Gardar intrusions, respectively. The earliest rocks ascribed to the Gardar period are terrestrial sandstones and lavas composing the Eriksfjord Formation that unconformably overlie the Paleoproterozoic basement rocks. One of the unsolved issues in the Gardar Province is to determine the precise age of the lavas from the Eriksfjord Formation, which can constrain the timing of the beginning of the Gardar rifting. In this study, for the first time, we presented precise U-Pb zircon ages of the lavas from the Eriksfjord Formation. Zircons were separated from five samples of basaltic lavas collected at the Motzfeldt Center for SHRIMP U-Pb zircon dating. All the zircons under CL image analysis show oscillatory zoning, indicative of magmatic origin, and their U-Pb ages were measured by SHRIMP at Korea Basic Science Institute. The mean 207Pb/206Pb ages of each sample range from 1315 - 1329 Ma, whereas the concordant 207Pb/206Pb ages from 1322 - 1327 Ma. When all of the analyzed data from five samples were considered together, they showed a normal distribution pattern and yielded a mean 207Pb/206Pb age of 1322.8 ± 4.7 Ma (MSWD = 0.04) and a concordant 207Pb/206Pb age of 1324.5 ± 3.4 Ma (MSWD = 0.04), respectively. These ages are consistent with the age of 1.35 - 1.31 Ga inferred from paleomagnetic data for the entire succession of the Eriksfjord Formation. Our ages suggest that the Gardar magmatism started at c. 1325 Ma and lasted until c. 1140 Ma in southern Greenland.

  19. Models for the beginning of sour cherry blossom

    2014-07-01

    Seven different model approaches to calculate the onset of sour cherry blossom for the main growing regions in Rhineland-Palatinate (Germany) were compared. Three of the approaches were pure forcing models (M1, M2, M2DL) and the remaining four models were combined sequential chilling-forcing (CF) models. Model M1 was the commonly used growing degree day (GDD) model in which the starting date of temperature accumulation ( t 1), the base temperature ( T BF) and the forcing requirement F* were optimized on the basis of observed data. Because of a relatively late optimal starting date ( t 1 = 1 March), the model can be applied only to calculate the onset of cherry blossom for present climate conditions. In order to develop forcing models that could possibly be used to estimate possible shifts in the timing of cherry blossom due to climate change, the starting date t 1 of the models was intentionally set to 1 January (M2, M2DL). Unfortunately, model M2 failed in both the optimization and validation period. The introduction of a daylength term (DL) in model M2DL improved model performance. In order to project possible shifts in the timing of plant phenological events, combined CF-models are preferred over pure GDD-models. For this reason four CF-models were developed with (M3DL, M4DL) and without (M3, M4) consideration of daylength in the GDD-approach. The chilling requirement was calculated using chilling hours (M3, M3DL) and chill portions (M4, M4DL). Both models without daylength estimated implausible model parameters and failed model validation. However, models M3DL and M4DL showed meaningful model parameter estimations and the error between modelled and observed data was markedly reduced. Moreover, the models optimized and validated (internal validation) for one sour cherry growing region in Germany, were applied successfully to calculate the beginning of the blossom period in other regions in Europe and even at one station in North America (external validation).

    Burundi, unlike most Central African nations, had a relatively rich precolonial history. A well-structured monarchy reigned from the beginning of the 16th century, according to some historians. A strong monarch of the early 19th century extended the borders of the country to approximately their current limits. In 1903, the country was conquered by the Germans, to be ceded to Belgium after Germany's defeat in World War I. After World War II, political parties seeking independence began to form. The UPRONA (Union for National Progress) party was founded by Prince Louis Rwagasore, and became the most active and best organized, attracting mass support. The party was banned by the colonial authorities on the grounds that the family of the king could not participate in elections or political activities. Nevertheless, the party triumphed in legislative elections in September 1961. Rwagasore was assassinated in October 1961. Independence was declared in July 1962. Successional struggles and tribal rivalries blocked efforts at reform of the government and economy. Civil war in 1972 saw the slaughter of between 100,000 and 300,000 citizens before order was restored with the aid of the Zairean army. The Second Republic was declared in a bloodless coup in 1976 by Colonel Bagaza. In the 1st years of his rule production increased, tentative efforts at industrialization were made, and schools and roads were constructed. Toward the end of his reign, however, he became increasingly jealous of his prerogatives and expelled, fired, or imprisoned members of government and high functionaries, and curbed the activities of the Catholic Church to which 65% of the population belonged. Relations with neighboring countries deteriorated while the nation's economic situation worsened. A coup in 1987 led by Major Buyoya was rapidly followed by release of political prisoners and improved relations with the Church and neighboring countries. Nevertheless, the country had a huge debt, prices for

  3. Prostate brachytherapy in patients with prior evidence of prostatitis

    International Nuclear Information System (INIS)

    Purpose: To refute a misconception that a prior history of prostatitis is a contraindication to prostate brachytherapy. Methods and Materials: Five patients with clinical or pathologic evidence of prior prostatitis were treated with transperineal brachytherapy. Four of the patients received a single i.v. dose of ciprofloxacin (500 mg) intraoperatively. Postimplant antibiotics were not given. The pretreatment biopsy slides were reviewed. Results: Two of the five patients developed postimplant urinary retention requiring short-term catheterization, and both resolved spontaneously. One patient developed what appeared to be an exacerbation of his chronic prostatitis. Conclusion: We continue to recommend prostate brachytherapy for the treatment of clinically organ-confined cancer, with no concern about prior clinical or pathologic evidence of prostatitis

    Approximate Message Passing (AMP) has been shown to be an excellent statistical approach to signal inference and compressed sensing problem. The AMP framework provides modularity in the choice of signal prior; here we propose a hierarchical form of the Gauss-Bernouilli prior which utilizes a Restricted Boltzmann Machine (RBM) trained on the signal support to push reconstruction performance beyond that of simple iid priors for signals whose support can be well represented by a trained binary RBM. We present and analyze two methods of RBM factorization and demonstrate how these affect signal reconstruction performance within our proposed algorithm. Finally, using the MNIST handwritten digit dataset, we show experimentally that using an RBM allows AMP to approach oracle-support performance.

    Estimating spectral reflectance has attracted extensive research efforts in color science and machine learning, motivated through a wide range of applications. In many practical situations, prior knowledge is available that ought to be used. Here, we have developed a general Bayesian method that allows the incorporation of prior knowledge from previous monochromator and spectrophotometer measurements. The approach yields analytical expressions for fast and efficient estimation of spectral reflectance. In addition to point estimates, probability distributions are also obtained, which completely characterize the uncertainty associated with the reconstructed spectrum. We demonstrate that, through the incorporation of prior knowledge, our approach yields improved reconstruction results compared with methods that resort to training data only. Our method is particularly useful when the spectral reflectance to be recovered resides beyond the scope of the training data. PMID:27409695

    Full Text Available A psycho-technology approach to discouraging guessing in multiple-choice formatted item can be done through reducing the a priori guessing probability of an item. This study proposes a psychometrics framework of Item Response Theory (IRT to model the effect of having various priori guessing probabilities across different items. A prior guessing parameter is proposed to serves as a moderator of the ability parameter in the two parameter logistic IRT. The results show that the proposed prior guessing parameter successfully moderates the ability parameters of the subjects with different degrees of guessing. However, the prior guessing parameter is insensitive when the performance pattern is mixed within the testlet but similar across testlet with different priori guessing probabilities.

    Material consistent with knowledge/experience is generally more memorable than material inconsistent with knowledge/experience - an effect that can be more extreme in older adults. Four experiments investigated knowledge effects on memory with young and older adults. Memory for familiar and unfamiliar proverbs (Experiment 1) and for common and uncommon scenes (Experiment 2) showed similar knowledge effects across age groups. Memory for person-consistent and person-neutral actions (Experiment 3) showed a greater benefit of prior knowledge in older adults. For cued recall of related and unrelated word pairs (Experiment 4), older adults benefited more from prior knowledge only when it provided uniquely useful additional information beyond the episodic association itself. The current data and literature suggest that prior knowledge has the age-dissociable mnemonic properties of (1) improving memory for the episodes themselves (age invariant), and (2) providing conceptual information about the tasks/stimuli extrinsically to the actual episodic memory (particularly aiding older adults).

    Metallic implants introduce severe artifacts in CT images, which degrades the image quality. It is an effective method to reduce metal artifacts by replacing the metal affected projection with the forward projection of a prior image. How to find a good prior image is the key of this class methods, and numerous algorithms have been proposed to address this issue recently. In this work, by using image mutual correlation, pixels in the original reconstructed image or linear interpolation corrected image, which are less affected by artifacts, are selected to build a combined image. Thereafter, a better prior image is generated from the combined image by using tissue classification. The results of three patients' CT images show that the proposed method can reduce metal artifacts remarkably.

    We revisit the multiple sparse priors (MSP) algorithm implemented in the statistical parametric mapping software (SPM) for distributed EEG source reconstruction (Friston et al., 2008). In the present implementation, multiple cortical patches are introduced as source priors based on a dipole source space restricted to a cortical surface mesh. In this note, we present a technique to construct volumetric cortical regions to introduce as source priors by restricting the dipole source space to a segmented gray matter layer and using a region growing approach. This extension allows to reconstruct brain structures besides the cortical surface and facilitates the use of more realistic volumetric head models including more layers, such as cerebrospinal fluid (CSF), compared to the standard 3-layered scalp-skull-brain head models. We illustrated the technique with ERP data and anatomical MR images in 12 subjects. Based on the segmented gray matter for each of the subjects, cortical regions were created and introduced as source priors for MSP-inversion assuming two types of head models. The standard 3-layered scalp-skull-brain head models and extended 4-layered head models including CSF. We compared these models with the current implementation by assessing the free energy corresponding with each of the reconstructions using Bayesian model selection for group studies. Strong evidence was found in favor of the volumetric MSP approach compared to the MSP approach based on cortical patches for both types of head models. Overall, the strongest evidence was found in favor of the volumetric MSP reconstructions based on the extended head models including CSF. These results were verified by comparing the reconstructed activity. The use of volumetric cortical regions as source priors is a useful complement to the present implementation as it allows to introduce more complex head models and volumetric source priors in future studies.

    This article describes the creation and development of a sustainable, community-supported children's bereavement camp. Numerous grief camps were examined prior to the project development. The project development was guided by the S.M.A.R.T. (S--Strategic/specific; M--Measurable; A--Achievable/attainable; R--Realistic; and T--Time-framed) stratagem to direct steps toward the development of the bereavement camp. Outcome measures included program participation, as well as evaluations completed by campers, family members, and volunteers. Camp attendance continues to grow, with 48 children the first year and an average of 65 the following 3 years. According to post-evaluation surveys, campers were able to integrate back into school with a decrease in stress and an increase in their ability to verbalize their grief, share feelings and begin to trust others. One child "got her sparkle back" according to her grandmother. Several campers commented that camp allowed them to see themselves as normal children. The goal of Camp Healing Hearts was that campers would laugh again, and they are. PMID:23977776

  17. Performance gain of displacement receiver with optimized prior probability

    International Nuclear Information System (INIS)

    We numerically study the performance of the displacement based quantum receiver for the discrimination of weak 3- and 4-phase-shift keyed (PSK) coherent state signals. We show that due to the nontrivial asymmetry of the receiver structure, optimization of the prior probability increases the mutual information and achieves sub-shot-noise limit discrimination. Moreover, we estimate the cutoff rate for a 4-PSK signal and confirm that the prior probability optimization shortens the code length for a given decoding error criterion. Such consideration for the asymmetric channel matrix is essential in a study of the compassable quantum receiver.

    We focused on describing low nutritional status in an increasing moose (Alces alces gigas) population with reduced predation in Game Management Unit (GMU) 20A near Fairbanks, Alaska, USA. A skeptical public disallowed liberal antlerless harvests of this moose population until we provided convincing data on low nutritional status. We ranked nutritional status in 15 Alaska moose populations (in boreal forests and coastal tundra) based on multiyear twinning rates. Data on age-of-first-reproduction and parturition rates provided a ranking consistent with twinning rates in the 6 areas where comparative data were available. Also, short-yearling mass provided a ranking consistent with twinning rates in 5 of the 6 areas where data were available. Data from 5 areas implied an inverse relationship between twinning rate and browse removal rate. Only in GMU 20A did nutritional indices reach low levels where justification for halting population growth was apparent, which supports prior findings that nutrition is a minor factor limiting most Alaska moose populations compared to predation. With predator reductions, the GMU 20A moose population increased from 1976 until liberal antlerless harvests in 2004. During 1997–2005, GMU 20A moose exhibited the lowest nutritional status reported to date for wild, noninsular, North American populations, including 1) delayed reproduction until moose reached 36 months of age and the lowest parturition rate among 36-month-old moose (29%, n = 147); 2) the lowest average multiyear twinning rates from late-May aerial surveys (x̄ = 7%, SE = 0.9%, n = 9 yr, range = 3–10%) and delayed twinning until moose reached 60 months of age; 3) the lowest average mass of female short-yearlings in Alaska (x̄ = 155 ± 1.6 [SE] kg in the Tanana Flats subpopulation, up to 58 kg below average masses found elsewhere); and 4) high removal (42%) of current annual browse biomass compared to 9–26% elsewhere in boreal forests.

  19. Why is cytoskeletal contraction required for cardiac fusion before but not after looping begins?

    Science.gov (United States)

    Shi, Yunfei; Varner, Victor D.; Taber, Larry A.

    2015-02-01

    Cytoskeletal contraction is crucial to numerous morphogenetic processes, but its role in early heart development is poorly understood. Studies in chick embryos have shown that inhibiting myosin-II-based contraction prior to Hamburger-Hamilton (HH) stage 10 (33 h incubation) impedes fusion of the mesodermal heart fields that create the primitive heart tube (HT), as well as the ensuing process of cardiac looping. If contraction is inhibited at or after looping begins at HH10, however, fusion and looping proceed relatively normally. To explore the mechanisms behind this seemingly fundamental change in behavior, we measured spatiotemporal distributions of tissue stiffness, stress, and strain around the anterior intestinal portal (AIP), the opening to the foregut where contraction and cardiac fusion occur. The results indicate that stiffness and tangential tension decreased bilaterally along the AIP with distance from the embryonic midline. The gradients in stiffness and tension, as well as strain rate, increased to peaks at HH9 (30 h) and decreased afterward. Exposure to the myosin II inhibitor blebbistatin reduced these effects, suggesting that they are mainly generated by active cytoskeletal contraction, and finite-element modeling indicates that the measured mechanical gradients are consistent with a relatively uniform contraction of the endodermal layer in conjunction with constraints imposed by the attached mesoderm. Taken together, our results suggest that, before HH10, endodermal contraction pulls the bilateral heart fields toward the midline where they fuse to create the HT. By HH10, however, the fusion process is far enough along to enable apposing cardiac progenitor cells to keep ‘zipping’ together during looping without the need for continued high contractile forces. These findings should shed new light on a perplexing question in early heart development.

(AUI), the nonprofit research corporation that operates the National Radio Astronomy Observatory (NRAO). They will be accompanied by their town's mayor. Myriam Nancy Rivera Mercado, Head of the high school in San Pedro, Gabriela Fernanda Rodriguez Moraleda, a tourism teacher there, and San Pedro Mayor Sandra Berna Martinez will begin a visit that includes classroom observations in the Magdalena schools, a reception hosted by the Magdalena Village Council, and a Mayor's Breakfast with Magdalena Mayor Jim Wolfe. They also will meet local residents, tour the Bosque del Apache National Wildlife Refuge with a second-grade class, visit an area ranch, tour the Very Large Array (VLA) radio telescope, and see Socorro's Community Arts Party. "These teachers will learn much about New Mexico, the United States, and our educational system, and will take this new knowledge back to their students and their community," said NRAO Education Officer Robyn Harrison. The visit is part of a Sister Cities program initiated and funded by AUI, which operates the NRAO for the U.S. National Science Foundation. Radio astronomy is a common link between San Pedro de Atacama and Magdalena. San Pedro is near the site of the Atacama Large Millimeter/submillimeter Array (ALMA), an international telescope project now under construction with funding by major partners in North America, Europe, and Japan. Magdalena is near the site of NRAO's VLA radio telescope. In Magdalena, the Village Council and Mayor Wolfe formalized their participation in the Sister Cities program last September, and San Pedro ratified the program in December. In San Pedro, the ceremony ratifying the agreement was attended by U.S. Ambassador to Chile Craig K

  7. A new learning method using prior information of neural networks

    Lü Baiquan; Junichi Murata; Kotaro Hirasawa

    2004-01-01

    In this paper, we present a new learning method using prior information for three-layered neural networks. Usually when neural networks are used for identification of systems, all of their weights are trained independently, without considering their inter-relation of weight values. Thus the training results are not usually good. The reason for this is that each parameter has its influence on others during the learning. To overcome this problem, first, we give an exact mathematical equation that describes the relation between weight values given by a set of data conveying prior information. Then we present a new learning method that trains a part of the weights and calculates the others by using these exact mathematical equations. In almost all cases, this method keeps prior information given by a mathematical structure exactly during the learning. In addition, a learning method using prior information expressed by inequality is also presented. In any case, the degree of freedom of networks (the number of adjustable weights) is appropriately limited in order to speed up the learning and ensure small errors. Numerical computer simulation results are provided to support the present approaches.

  11. An Adaptively Accelerated Bayesian Deblurring Method with Entropy Prior

    Directory of Open Access Journals (Sweden)

    Yong-Hoon Kim

    2008-05-01

    Full Text Available The development of an efficient adaptively accelerated iterative deblurring algorithm based on Bayesian statistical concept has been reported. Entropy of an image has been used as a “prior” distribution and instead of additive form, used in conventional acceleration methods an exponent form of relaxation constant has been used for acceleration. Thus the proposed method is called hereafter as adaptively accelerated maximum a posteriori with entropy prior (AAMAPE. Based on empirical observations in different experiments, the exponent is computed adaptively using first-order derivatives of the deblurred image from previous two iterations. This exponent improves speed of the AAMAPE method in early stages and ensures stability at later stages of iteration. In AAMAPE method, we also consider the constraint of the nonnegativity and flux conservation. The paper discusses the fundamental idea of the Bayesian image deblurring with the use of entropy as prior, and the analytical analysis of superresolution and the noise amplification characteristics of the proposed method. The experimental results show that the proposed AAMAPE method gives lower RMSE and higher SNR in 44% lesser iterations as compared to nonaccelerated maximum a posteriori with entropy prior (MAPE method. Moreover, AAMAPE followed by wavelet wiener filtering gives better result than the state-of-the-art methods.

  14. Cosmological limits on neutrino unknowns versus low redshift priors

    Science.gov (United States)

    Di Valentino, Eleonora; Giusarma, Elena; Mena, Olga; Melchiorri, Alessandro; Silk, Joseph

    2016-04-01

    Recent cosmic microwave background (CMB) temperature and polarization anisotropy measurements from the Planck mission have significantly improved previous constraints on the neutrino masses as well as the bounds on extended models with massless or massive sterile neutrino states. However, due to parameter degeneracies, additional low redshift priors are mandatory in order to sharpen the CMB neutrino bounds. We explore here the role of different priors on low redshift quantities, such as the Hubble constant, the cluster mass bias, and the reionization optical depth τ . Concerning current priors on the Hubble constant and the cluster mass bias, the bounds on the neutrino parameters may differ appreciably depending on the choices adopted in the analyses. With regard to future improvements in the priors on the reionization optical depth, a value of τ =0.05 ±0.01 , motivated by astrophysical estimates of the reionization redshift, would lead to ∑mνbaryon acoustic oscillation, and Planck clusters data, thereby opening the window to unravel the neutrino mass hierarchy with existing cosmological probes.

  16. VIDEO CONTENTS PRIOR STORING SERVER FOR OPTICAL ACCESS NETWORK

    Directory of Open Access Journals (Sweden)

    2015-03-01

    Full Text Available One of the most important multimedia applications is Internet protocol TV (IPTV for next-generation networks. IPTV provides triple-play services that require high-speed access networks with the functions of multicasting and quality of service (QoS guarantees. Among optical access networks, Ethernet passive optical networks (EPONs are regarded as among the best solutions to meet higher bandwidth demands. In this paper, we propose a new architecture for multicasting live IPTV traffic in optical access network. The proposed mechanism involves assigning a unique logical link identifier to each IPTV channel. To manage multicasting, a prior storing server in the optical line terminal (OLT and in each optical network unit (ONU is constructed. In this work, we propose a partial prior storing strategy that considers the changes in the popularity of the video content segments over time and the access patterns of the users to compute the utility of the objects in the prior storage. We also propose to partition the prior storage to avoid the eviction of the popular objects (those not accessed frequently by the unpopular ones which are accessed with higher frequency. The popularity distribution and ageing of popularity are measured from two online datasets and use the parameters in simulations. Simulation results show that our proposed architecture can improve the system performance and QoS parameters in terms of packet delay, jitter and packet loss
