  2. Does biological relatedness affect child survival?


    Full Text Available Objective: We studied child survival in Rakai, Uganda where many children are fostered out or orphaned. Methods: Biological relatedness is measured as the average of the Wright's coefficients between each household member and the child. Instrumental variables for fostering include proportion of adult males in household, age and gender of household head. Control variables include SES, religion, polygyny, household size, child age, child birth size, and child HIV status. Results: Presence of both parents in the household increased the odds of survival by 28%. After controlling for the endogeneity of child placement decisions in a multivariate model we found that lower biological relatedness of a child was associated with statistically significant reductions in child survival. The effects of biological relatedness on child survival tend to be stronger for both HIV- and HIV+ children of HIV+ mothers. Conclusions: Reductions in the numbers of close relatives caring for children of HIV+ mothers reduce child survival.

  4. Multidimensional poverty and child survival in India.

    Sanjay K Mohanty

    Full Text Available BACKGROUND: Though the concept of multidimensional poverty has been acknowledged cutting across the disciplines (among economists, public health professionals, development thinkers, social scientists, policy makers and international organizations and included in the development agenda, its measurement and application are still limited. OBJECTIVES AND METHODOLOGY: Using unit data from the National Family and Health Survey 3, India, this paper measures poverty in multidimensional space and examine the linkages of multidimensional poverty with child survival. The multidimensional poverty is measured in the dimension of knowledge, health and wealth and the child survival is measured with respect to infant mortality and under-five mortality. Descriptive statistics, principal component analyses and the life table methods are used in the analyses. RESULTS: The estimates of multidimensional poverty are robust and the inter-state differentials are large. While infant mortality rate and under-five mortality rate are disproportionately higher among the abject poor compared to the non-poor, there are no significant differences in child survival among educationally, economically and health poor at the national level. State pattern in child survival among the education, economical and health poor are mixed. CONCLUSION: Use of multidimensional poverty measures help to identify abject poor who are unlikely to come out of poverty trap. The child survival is significantly lower among abject poor compared to moderate poor and non-poor. We urge to popularize the concept of multiple deprivations in research and program so as to reduce poverty and inequality in the population.

  5. A Child Survival and Development Revolution?

  6. [Problems and priorities in child survival].

    Bobadilla, J L


    This work synthesizes the conclusions and recommendations of the 1985 International Workshop on Child Survival held in Teotihuacan, Mexico. Data are presented which document the extent of the problem of child survival in Latin America and the deficiencies of available data. Malnutrition, diseases preventable through vaccination, diarrheal diseases, acute respiratory infections, perinatal disorders, and shortcomings in quality of care are separately discussed following an assessment of their socioeconomic and cultural determining factors. Recent advances in the preventive component of primary health care programs are discussed. In Latin America, 900 of each 1000 live born babies survive to the 5th year of life compared to 980 in developed countries. Although the mortality rate of children under 5 in Latin America declined from 128 in 1950-55 to 63 in 1980-85, there are wide disparities between countries. Most countries of Latin America were classified as having high or very high infant and child mortality. There are serious differences in child survival between geographic regions and social groups of each country. The mortality decline in Costa Rica, Cuba, and Chile demonstrates that other countries could avoid a large proportion of deaths by ensuring that benefits of current programs have broader coverage. The severe economic crisis in Mexico and other countries threatens the progress already achieved in child survival. The recommendations of the conference are based on the premise that recent efforts to improve survival have been insufficient and a more rational use of the available resources and knowledge is required. In the area of health policy, priority should continue to be given to providing care for mothers and small children. Investments should be reoriented toward extending coverage of primary health care. The proportion of mothers attended during delivery by trained paramedical personnel or physicians should be increased, and family planning programs in

  8. Enhancing the child survival agenda to promote, protect, and support early child development.

    Jensen, Sarah K G; Bouhouch, Raschida R; Walson, Judd L; Daelmans, Bernadette; Bahl, Rajiv; Darmstadt, Gary L; Dua, Tarun


    High rates of child mortality and lost developmental potential in children under 5 years of age remain important challenges and drivers of inequity in the developing world. Substantive progress has been made toward Millennium Development Goal (MDG) 4 to improve child survival, but as we move into the post-2015 sustainable development agenda, much more work is needed to ensure that all children can realize their full and holistic physical, cognitive, psychological, and socio-emotional development potential. This article presents child survival and development as a continuous and multifaceted process and suggests that a life-course perspective of child development should be at the core of future policy making, programming, and research. We suggest that increased attention to child development, beyond child survival, is key to operationalize the sustainable development goals (SDGs), address inequities, build on the demographic dividend, and maximize gains in human potential. An important step toward implementation will be to increase integration of existing interventions for child survival and child development. Integrated interventions have numerous potential benefits, including optimization of resource use, potential additive impacts across multiple domains of health and development, and opportunity to realize a more holistic approach to client-centered care. However, a notable challenge to integration is the continued division between the health sector and other sectors that support child development. Despite these barriers, empirical evidence is available to suggest that successful multisectoral coordination is feasible and leads to improved short- and long-term outcomes in human, social, and economic development.

  9. Parents' Death and its Implications for Child Survival

    Atrash, Hani K.


    Reduction of child mortality is a global public health priority. Parents can play an important role in reducing child mortality. The inability of one or both parents to care for their children due to death, illness, divorce or separation increases the risk of death of their children. There is increasing evidence that the health, education, and socioeconomic status of mothers and fathers have significant impact on the health and survival of their children. We conducted a literature review to e...

  10. The puzzle of Muslim advantage in child survival in India

    Bhalotra, Sonia; Valente, Christine; Soest, Arthur


    The socio-economic status of Indian Muslims is, on average, considerably lower than that of upper caste Hindus. Muslims have higher fertility and shorter birth spacing and are a minority group that, it has been argued, have poorer access to public goods. They nevertheless exhibit substantially higher child survival rates, and have done for decades. This paper documents and analyses this seeming puzzle. The religion gap in survival is much larger than the gender gap but, in contrast to the gen...

  11. Are global and regional improvements in life expectancy and in child, adult and senior survival slowing?

    Ryan J Hum

    Full Text Available Improvements in life expectancy have been considerable over the past hundred years. Forecasters have taken to applying historical trends under an assumption of continuing improvements in life expectancy in the future. A linear mixed effects model was used to estimate the trends in global and regional rates of improvements in life expectancy, child, adult, and senior survival, in 166 countries between 1950 and 2010. Global improvements in life expectancy, including both child and adult survival rates, decelerated significantly over the study period. Overall life expectancy gains were estimated to have declined from 5.9 to 4.0 months per year for a mean deceleration of -0.07 months/year2; annual child survival gains declined from 4.4 to 1.6 deaths averted per 1000 for a mean deceleration of -0.06 deaths/1000/year2; adult survival gains were estimated to decline from 4.8 to 3.7 deaths averted per 1000 per year for a mean deceleration of -0.08 deaths/1000/year2. Senior survival gains however increased from 2.4 to 4.2 deaths averted per 1000 per year for an acceleration of 0.03 deaths/1000/year2. Regional variation in the four measures was substantial. The rates of global improvements in life expectancy, child survival, and adult survival have declined since 1950 despite an increase in the rate of improvements among seniors. We postulate that low-cost innovation, related to the last half-century progress in health-primarily devoted to children and middle age, is reaping diminishing returns on its investments. Trends are uneven across regions and measures, which may be due in part to the state of epidemiological transition between countries and regions and disparities in the diffusion of innovation, accessible only in high-income countries where life expectancy is already highest.

  13. The unfinished child survival revolution: the role of nutrition

    Persson, Lars-Åke


    Since an impressive reduction in child mortality in the 1970s to early 1990s improvements have slowed down, and more than 10 million children die annually under the age of 5 years. Most of these deaths occur in relatively few countries, mainly in South Asia and Africa south of the Sahara. Given the causal links between nutrition and mortality in infancy and childhood it is of great importance to assess the role of nutrition in further improvements in global child survival. This study assessed...

  14. How Nigeria built child survival themes into national television.

    Gleason, G


    As part of the Government of Nigeria's goal of providing universal child immunization, a strategy was developed to strengthen the production capacity of the Nigerian Television Authority (NTA) and to award higher priority to health issues in NTA programming. At the national level, a child survival-oriented training, coordination, and production unit was established to produce "spot messages" on primary health care. In 1985-86, radio and television staff from all Nigerian states attended workshops at which Ministry of Health officials outlined Nigeria's maternal-child health problems and emphasized the potential of the broadcast media in health education. Each station was linked with an officer in the local Ministry of Health to ensure ongoing collaboration on technical problems and health programs in need of promotion. Another set of state-level workshops brought together media producers and radio and television writers to encourage them to integrate primary health care themes into their programs. In addition, a Nigerian nongovernmental organization has organized workshops for electronic media writers and producers aimed at incorporating family planning themes into several popular television programs. In 1986, both NTA and the Federal Radio Corporation of Nigeria signed agreements further committing their networks to the child survival campaign. The Nigerian experience exemplifies the potential for creating and institutionalizing long-term efforts to use the mass media to bring new information to the general population on health-related issues. Needed at this point is more knowledge about specific communication strategies that are most effective in promoting sustainable behavioral change on the family and community levels in a country with much social and cultural diversity.

  15. The effect of maternal healthcare on the probability of child survival in Azerbaijan.

    Habibov, Nazim; Fan, Lida


    This study assesses the effects of maternal healthcare on child survival by using nonrandomized data from a cross-sectional survey in Azerbaijan. Using 2SLS and simultaneous equation bivariate probit models, we estimate the effects of delivering in healthcare facility on probability of child survival taking into account self-selection into the treatment. For women who delivered at healthcare facilities, the probability of child survival increases by approximately 18%. Furthermore, if every woman had the opportunity to deliver in healthcare facility, then the probability of child survival in Azerbaijan as a whole would have increased by approximately 16%.

  17. Integration of HIV in child survival platforms: a novel programmatic pathway towards the 90–90–90 targets

    Dick D Chamla


    Full Text Available Introduction: Integration of HIV into child survival platforms is an evolving territory with multiple connotations. Most literature on integration of HIV into other health services focuses on adults; however promising practices for children are emerging. These include the Double Dividend (DD framework, a new programming approach with dual goal of improving paediatric HIV care and child survival. In this commentary, the authors discuss why integrating HIV testing, treatment and care into child survival platforms is important, as well as its potential to advance progress towards global targets that call for, by 2020, 90% of children living with HIV to know their status, 90% of those diagnosed to be on treatment and 90% of those on treatment to be virally suppressed (90–90–90. Discussion: Integration is critical in improving health outcomes and efficiency gains. In children, integration of HIV in programmes such as immunization and nutrition has been associated with an increased uptake of HIV infant testing. Integration is increasingly recognized as a case-finding strategy for children missed from prevention of mother-to-child transmission programmes and as a platform for diffusing emerging technologies such as point-of-care diagnostics. These support progress towards the 90–90–90 targets by providing a pathway for early identification of HIV-infected children with co-morbidities, prompt initiation of treatment and improved survival. There are various promising practices that have demonstrated HIV outcomes; however, few have documented the benefits of integration on child survival interventions. The DD framework is well positioned to address the bidirectional impacts for both programmes. Conclusions: Integration provides an important programmatic pathway for accelerated progress towards the 90–90–90 targets. Despite this encouraging information, there are still challenges to be addressed in order to maximize the benefits of integration.

  18. Magnetized Gas Clouds can Survive Acceleration by a Hot Wind

    McCourt, Michael; Madigan, Ann-Marie; Quataert, Eliot


    We present three-dimensional magnetohydrodynamic simulations of magnetized gas clouds accelerated by hot winds. We initialize gas clouds with tangled internal magnetic fields and show that this field suppresses the disruption of the cloud: rather than mixing into the hot wind as found in hydrodynamic simulations, cloud fragments end up co-moving and in pressure equilibrium with their surroundings. We also show that a magnetic field in the hot wind enhances the drag force on the cloud by a factor ~(1+v_A^2/v_wind^2)$, where v_A is the Alfven speed in the wind and v_wind measures the relative speed between the cloud and the wind. We apply this result to gas clouds in several astrophysical contexts, including galaxy clusters, galactic winds, the Galactic center, and the outskirts of the Galactic halo. Our results can explain the prevalence of cool gas in galactic winds and galactic halos and how such cool gas survives in spite of its interaction with hot wind/halo gas. We also predict that drag forces can lead t...

  19. Birth weight: a major determinant of child survival.


    The problems of maternal malnutrition, low birthweight, and infant mortality and morbidity were investigated in a prospective study (1981-85) involving 7586 pregnant women (3197 from urban areas and 4389 from rural areas) in India. The mothers were followed until their infants were 1 year of age. There were 6879 live births among these women and 208 still births (a rate of 29.3/1000 deliveries). The perinatal, neonatal, and infant mortality rates were 65.3/1000, 57.7/1000, and 94.5/1000, respectively. 90% of these deaths involved infants with a birthweight below 2000 grams. Overall, 39% of infants studied were classified as low birthweight (under 2500 grams). Factors associated with low birthweight included maternal age below 19 years or over 35 years, maternal weight below 40 kg, maternal height below 145 cm, weight gain during pregnancy of under 5 kg, an interpregnancy interval less than 24 months, hemoglobin less than 8 grams%, and maternal illiteracy. Moderate to severe morbidity (neonatalas phyxia) was found in 10% of the births in this series. Breastfeeding was delayed beyond 24 hours in 77% of rural births and 13% of urban births; 30% of infants in both settings were given a bottle within the 1st week of life. 98% of rural mothers and 85% of urban mothers did not utilize available maternal-child health services in the postpartum period. Reducing the incidence of low birthweight births through primary health care interventions such as screening, food supplementation, adequate prenatal care, and correction of maternal nutritional deficiencies is the best strategy for improving infant survival in India. In the interim period, adequate health care must be made available to low birthweight infants and proper feeding practices should be promoted. PMID:3440594

  20. Birth Spacing and Child Survival: Comparative Evidence from India and Pakistan*

    Pushkar Maitra; Sarmistha Pal


    In view of higher fertility and mortality rates in Pakistan compared to India, this paper examines the two-way relationship between birth interval and child mortality and compares the behaviour of households in the Indian and Pakistani provinces of Punjab. Birth interval and child survival are modelled here as correlated hazard processes to address the bias generated by the simultaneity between spacing and survival. We find evidence of significant mutual dependence between birth interval and ...

  1. The life-history trade-off between fertility and child survival

    Lawson, D. W.; Alvergne, A.; Gibson, M. A.


    Evolutionary models of human reproduction argue that variation in fertility can be understood as the local optimization of a life-history trade-off between offspring quantity and 'quality'. Child survival is a fundamental dimension of quality in these models as early-life mortality represents a crucial selective bottleneck in human evolution. This perspective is well-rehearsed, but current literature presents mixed evidence for a trade-off between fertility and child survival, and little empi...

It highlights the need to expand professional supports that repair and strengthen mother-child relationsh...

  3. Somalia: supporting the child survival agenda when routine health service is broken.

    Mirza, Imran Raza; Kamadjeu, Raoul; Assegid, Kebede; Mulugeta, Abraham


    Somalia, one of the most unstable countries in the world, has been without a permanent government for nearly 2 decades. With a health system in total disarray, coverage of basic health interventions remains low and, maternal and child mortality is among the highest in the world. Health partners jointly outlined an integrated package of critical child survival interventions to be delivered through a population-based delivery strategy known as Child Health Days (CHDs), to reduce child mortality. Using this strategy, key child survival interventions are delivered to the community with an objective of reaching children areas, and coverage disparity between the urban and rural areas was reduced from 17% (42% urban and 25% rural) to 10% (50% urban and 60% rural). In addition, infants were reached with a third dose of diphtheria-pertussis-tetanus vaccine, achieving 51% coverage during 2009 and 66% in 2010. This paper summarizes the challenges of scaling up child interventions in the troubled context of Somalia by reviewing the planning, implementation, and achievements of CHDs as well as reflecting on challenges for the future of child survival in Somalia.

  4. Women's status and child survival in West Java, Indonesia.



    This study is introduced by a literature review of the concept of women's status, and related factors that determine infant and child mortality. Women's status is primarily defined by education, occupation and economic activity, which affect women's decision-making in the home and their independence in larger society. Cluster analysis was used to identify geographical patterns of standardized women's status variables among 20 regencies and 4 municipalities in West Java. Euclidian distances were computed between pairs of regencies across the 13 indicators. Pearson's correlations and multiple regression were used to compare associations between women's status variables and infant and child mortality, after controlling for economic development. Using data from the 1980 census, the study demonstrated large regional variations in women's status in West Java, with higher status in both the household and in society in the south and central highlands than in the north and west. Women's status is closely related to infant and child mortality, independent of the level of development. There was 1 notable exception, the municipality of Bogor, where infant and child mortality were higher than average rates for the cluster of areas with higher women's status. The results suggest that improved education, and increase in age at 1st marriage are key elements for improving the status of women in West Java. PMID:12343263

  5. Comments on "Child Survival and Changing Fertility Patterns in Pakistan".

    Siddiqui, K A


    The distillation of Zeba Sathar's article on the determinants of fertility decline and child mortality decline is that marriage age and contraceptive surgery could be important factors in bringing about changes in both fertility and child mortality in Pakistan. The concern is that 80 out of 115 million Pakistanis live in rural areas where marriage age is very low and program efforts are limited or nonexistent. The question is raised about how to effectuate changes in attitudes in rural areas to increase marriage age. Another point is made about the simplicity of explanations for fertility and mortality change, when the reality is a complex host of interactive socioeconomic, cultural, social, and program factors that are responsible for fertility at present levels. The suggestion is for development of a more appropriate model of fertility at the micro level which illuminates the interaction of these factors in determining fertility. Sathar is reported to have concluded that the impact of infant and child mortality on fertility was inconclusive. The changing patterns of fertility are likely to bring about a change in the demand for children and a lesser preference for gender; this status change for women will further reduce child mortality and fertility. Large family sizes are postulated to be associated with close spacing and greater concentrations of children under 5 years of age competing for physical resources and having a high risk of infection with inadequate parental attention and care. These conditions occur in families with low income and little parental education. Institutional and community services also affect child mortality. There are also examples of educational opportunity and income equality as factors bringing about demographic change in Sri Lanka and Kerala, India. The author speculates that an outcome of development is increased educational attainment and more equitable distribution of income. Low levels of maternal education are associated with

  6. The Emotional Child Witness Effect Survives Presentation Mode.

    Melinder, Annika; Burrell, Lisa; Eriksen, Maria Olaussen; Magnussen, Svein; Wessel, Ellen


    The emotional witness effect - the phenomenon whereby people are affected by the emotional manner in which a witness presents testimony - constitutes a possible source of wrongful decisions in legal contexts. One stereotypical view of abused children is that they should be sad when talking about their experiences of maltreatment, whereas children may in fact express a variety of emotional expressions when talking about abusive events. This raises the question as to whether there is an optimal mode in which to present child victim testimony that could reduce the possible influence of displayed emotions. In the present study, mock police interviews were carried out with female child actors, role-playing the victims of physical abuse by their stepfather, telling the same story with four emotional expressions (neutral, sad, angry, or positive). Laypersons (N = 465) were presented with the interviews as transcripts with the emotional reactions of the child witness noted, audio recordings, or videotaped recordings. Participants then rated the credibility of the victim witness. Replicating previous results, the "sad" expression elicited the highest credibility ratings across all modes of presentations. Presentation mode affected ratings of credibility, with the transcript versions resulting in the highest ratings. Copyright © 2016 John Wiley & Sons, Ltd. PMID:26990221

    Krishnan, Anand


    Background: While substantial progress has been made globally towards achieving United Nations Millennium Development Goal 4 (MDG 4) on child mortality, the decline is not sufficient to reach the targets set for 2015. The South Asian region, which includes India, was to achieve the MDG 4 target of 39 deaths per 1000 live births by 2015 but was estimated to have reached only 61 by 2011. A part of this under-achievement is due to the gender-differentials in child mortality in South-Asia. The in...

    Under-five mortality rate is a key indicator of the level of child health and overall well-being of a given population and is an indicator of the United Nations Millennium Development Goals 4. Of the estimated more than 10 million children that die worldwide each year, 41% of these deaths occur in sub-Saharan Africa. With over one million children dying yearly from preventable diseases in Nigeria, the country may not meet the other Millennium Development Goals by 2015. Child...

  10. No survival of Nonlocalilty of fermionic quantum states with alpha vacuum in the infinite acceleration limit

    Kwon, Younghun, E-mail:


    In this article, we investigate the nonlocal behavior of the quantum state of fermionic system having the alpha vacuum. We evaluate the maximum violation of CHSH inequality in the quantum state. Even when the maximally entangled quantum state is initially shared it cannot violate the CHSH inequality, regardless of any alpha vacuum, when the infinite acceleration is applied. It means that the nonlocality of the quantum state in fermionic system with the alpha vacuum cannot survive in the infinite acceleration limit.

    Garenne, Michel; Darkaoui, Nada; Braikat, Mhamed; Azelmat, Mustapha


    This study was carried out to evaluate the trends in cause-specific mortality and the impact of child-survival programmes in Morocco. Two national surveys on causes and circumstances of child deaths were conducted in Morocco in 1988 and 1998 (ECCD-1 and ECCD-2 respectively). These surveys were based on a representative sample of deaths of children aged less than five years (432 and 866 respectively). Causes of death were assessed by verbal autopsy and were validated on a subsample of 94 cases...

  12. Effects of Malnutrition on Child Survival in China As Estimated by PROFILES



    Objective To estimate the benefits of reductions in underweight and Vitamin A deficiency forchild survival in China that might be expected as a result of lowering the prevalence of theseconditions. Methods Profiles, a process of nutrition policy analysis was used to quantify thefunctional consequences of malnutrition in terms of child survival. Results Underweight Theactual reduction in underweight between 1992 and 2001 (from 15.7% to the current 10.1%) resultedin saving of 176 000 child lives. As estimated, without improvements, 612 000 children will die due tounderweight between 2001 and 2010, 281 000 (46%) of them living in western provinces. Reducingunderweight prevalence from 10.1% to 8% could overall save 62 000 lives. The reduction ofunderweight prevalence in the west alone might save 56 000 lives. Vitamin A in China as a whole,vitamin A deficiency accounts, as estimated, for 7.5% of deaths of children 6-59 months old,representing 206 000 deaths over the past ten years. Halving the prevalence over the period wouldsave 49 000 child lives. The higher prevalence and higher mortality rates in western provinces meanthat even with only 28% of the Chinese population, over half of child deaths there are related tovitamin A.

  13. MELD vs Child-Pugh and creatinine-modified Child-Pugh score for predicting survival in patients with decompensated cirrhosis

    George V. Papatheodoridis; Evangelos Cholongitas; Eleni Dimitriadou; Giota Touloumi; Vassilios Sevastianos; Athanasios J. Archimandritis


    AIM: Model of End-stage Liver Disease (MELD) score has recently gained wide acceptance over the old Child-Pugh score in predicting survival in patients with decompensated cirrhosis, although it is more sophisticated. We compared the predictive values of MELD, Child-Pugh and creatinine modified Child-Pugh scores in decompensated cirrhosis. METHODS: A cohort of 102 patients with decompensated cirrhosis followed-up for a median of 6 mo was studied.Two types of modified Child-Pugh scores estimated by adding 0-4 points to the original score using creatinine levels as a sixth categorical variable were evaluated.RESULTS: The areas under the receiver operating characteristic curves did not differ significantly among the four scores, but none had excellent diagnostic accuracy (areas:0.71-0.79). Child-Pugh score appeared to be the worst, while the accuracy of MELD was almost identical with that of modified Child-Pugh in predicting short-term and slightly better in predicting medium-term survival. In Cox regression analysis, all four scores were significantly associated with survival, while MELD and creatinine-modified Child-Pugh scores had better predictive values (c-statistics: 0.73 and 0.69-0.70) than Child-Pugh score (c-statistics: 0.65). Adjustment for gamma-glutamate transpeptidase levels increased the predictive values of all systems (c-statistics: 0.77-0.81). Analysis of the expected and observed survival curves in patients subgroups according to their prognosis showed that all models fit the data reasonably well with MELD probably discriminating better the subgroups with worse prognosis. CONCLUSION: MELD compared to the old Child-Pugh and particularly to creatinine-modified Child-Pugh scores does not appear to offer a clear advantage in predicting survival in patients with decompensated cirrhosis in daily clinical practice.

  14. What has faith got to do with it? Religion and child survival in Ghana.

    Gyimah, Stephen Obeng


    Using pooled children data from the 1998 and 2003 Ghana Demographic and Health Surveys, this study examines religious differences in child survival in Ghana. Guided by the particularized theology and selectivity theses, a piecewise constant hazard model with gamma-shared frailty is used to explore if there are denominational differences in child mortality, and whether these could be explained through other characteristics. At the bivariate level, children whose mothers identified as Muslim and Traditional were found to have a significantly higher risk of death compared with their counterparts whose mothers identified as Christians. In the multivariate models, however, the religious differences disappeared after the mediating and confounding influence of socioeconomic factors were controlled. The findings provide support for the selectivity hypothesis, which is based on the notion that religious variations mainly reflect differential access to social and human capital rather than religious theology per se.

  15. Survivability of integrated PVDF film sensors to accelerated ageing conditions in aeronautical/aerospace structures

    This work validates the use of integrated polyvinylidene fluoride (PVDF) film sensors for dynamic testing, even after being subjected to UV-thermo-hygro-mechanical accelerated ageing conditions. The verification of PVDF sensors’ survivability in these environmental conditions, typically confronted by civil and military aircraft, is the main concern of the study. The evaluation of survivability is made by a comparison of dynamic testing results provided by the PVDF patch sensors subjected to an accelerated ageing protocol, and those provided by neutral non-aged sensors (accelerometers). The available measurements are the time-domain response signals issued from a modal analysis procedure, and the corresponding frequency response functions (FRF). These are in turn used to identify the constitutive properties of the samples by extraction of the modal parameters, in particular the natural frequencies. The composite specimens in this study undergo different accelerated ageing processes. After several weeks of experimentation, the samples exhibit a loss of stiffness, represented by a decrease in the elastic moduli down to 10%. Despite the ageing, the integrated PVDF sensors, subjected to the same ageing conditions, are still capable of providing reliable data to carry out a close followup of these changes. This survivability is a determinant asset in order to use integrated PVDF sensors to perform structural health monitoring (SHM) in the future of full-scale composite aeronautical structures. (paper)

    Moriarty, Paul; Burke, Christopher; McCrossin, David; Campbell, Robert; Cherian, Sarah; Shahab, Mohammad Shekeeb; Visvesvara, Govinda S; Nourse, Clare


    Balamuthia mandrillaris causes granulomatous amoebic encephalitis, which is frequently fatal. There are few reports of survival in children. A 4-year-old child developed severe meningoencephalitis with multiple intracranial ring-enhancing lesions. Empiric therapy was commenced after a biopsy was performed, and the patient had a good clinical response. Molecular testing and indirect immunofluorescence later confirmed the diagnosis of Balamuthia encephalitis. Diagnosis of Balamuthia encephalitis is often delayed. The literature is reviewed with particular reference to reported survival. Prompt tissue diagnosis and initiation of therapy are common features among survivors. In previous reports, miltefosine was not used to treat children, but it was well tolerated in this case and should be considered as a therapeutic option. PMID:26624913

    Background Household surveys undertaken in Niger since 1998 have revealed steady declines in under-5 mortality which have placed the country ‘on track’ to reach the fourth Millennium Development goal (MDG). This paper explores Niger’s mortality and health coverage data for children under-5 years of age up to 2012 to describe trends in high impact interventions and the resulting impact on childhood deaths averted. The sustainability of these trends are also considered. Methods and Findings Estimates of child mortality using the 2012 Demographic and Health Survey were developed and maternal and child health coverage indicators were calculated over four time periods. Child survival policies and programmes were documented through a review of documents and key informant interviews. The Lives Saved Tool (LiST) was used to estimate the number of child lives saved and identify which interventions had the largest impact on deaths averted. The national mortality rate in children under-5 decreased from 286 child deaths per 1000 live births (95% confidence interval 177 to 394) in the period 1989–1990 to 128 child deaths per 1000 live births in the period 2011–2012 (101 to 155), corresponding to an annual rate of decline of 3.6%, with significant declines taking place after 1998. Improvements in the coverage of maternal and child health interventions between 2006 and 2012 include one and four or more antenatal visits, maternal Fansidar and tetanus toxoid vaccination, measles and DPT3 vaccinations, early and exclusive breastfeeding, oral rehydration salts (ORS) and proportion of children sleeping under an insecticide-treated bed net (ITN). Approximately 26,000 deaths of children under-5 were averted in 2012 due to decreases in stunting rates (27%), increases in ORS (14%), the Hib vaccine (14%), and breastfeeding (11%). Increases in wasting and decreases in vitamin A supplementation negated some of those gains. Care seeking at the community level was responsible for an

  19. Prolonged survival when temozolomide is added to accelerated radiotherapy for glioblastoma multiforme

    The goal of this study was to evaluate accelerated radiotherapy with and without temozolomide (TMZ) for glioblastoma multiforme (GBM). This retrospective analysis evaluated 86 patients with histologically proven GBM who were treated with accelerated radiotherapy of 1.8 Gy twice daily to a total dose of 54 Gy within 3 weeks. Median age was 62 years and median Karnofsky index was 90. A total of 41 patients received radiotherapy only from 2002-2005 and 45 patients were treated with TMZ concomitantly and after radiotherapy from 2005-2007. Median overall survival (OS) was 12.5 months and 2-year OS was 15.4%. Patient characteristics were well balanced between the two groups except for better performance status (p = 0.05) and higher frequency of retreatment for the first recurrence (p = 0.02) in the TMZ group. Age at diagnosis (HR 2.83) and treatment with TMZ (HR 0.60) were correlated with OS in the multivariate analysis: treatment with and without TMZ resulted in median OS of 16 months and 11.3 months, respectively. Hematological toxicity grade > II was observed in 2/45 patients and 5/37 patients during simultaneous radiochemotherapy and adjuvant TMZ. TMZ added to accelerated radiotherapy for GBM resulted in prolonged overall survival with low rates of severe hematological toxicity. (orig.)

    (1) BACKGROUND: Supplementary feeding programs (SFPs) are effective in the community-based treatment of moderate acute malnutrition (MAM) and prevention of severe acute malnutrition (SAM); (2) METHODS: A retrospective study was conducted on a sample of 1266 Zambian malnourished children assisted from 2012 to 2014 in the Rainbow Project SFPs. Nutritional status was evaluated according to WHO/Unicef methodology. We performed univariate and multivariate Cox proportional risk regression to identify the main predictors of mortality. In addition, a time-to event analysis was performed to identify predictors of failure and time to cure events; (3) RESULTS: The analysis included 858 malnourished children (19 months ± 9.4; 49.9% males). Program outcomes met international standards with a better performance for MAM compared to SAM. Cox regression identified SAM (3.8; 2.1-6.8), HIV infection (3.1; 1.7-5.5), and WAZ death. Time to event showed 80% of children recovered by SAM/MAM at 24 weeks. (4) CONCLUSIONS: Preventing deterioration of malnutrition, coupled to early detection of HIV/AIDS with adequate antiretroviral treatment, and extending the duration of feeding supplementation, could be crucial elements for ensuring full recovery and improve child survival in malnourished Zambian children.

    Background: Maternal mortality remains the leading cause of death and disability for reproductive-age women in resource-poor countries. The impact of a mother’s death on child outcomes is likely severe but has not been well quantified. This analysis examines survival outcomes for children whose mothers die during or shortly after childbirth in Butajira, Ethiopia. Methods: This study uses data from the Butajira Health and Demographic Surveillance System (HDSS) site. Child outcomes were assesse...

  3. Explaining equity gains in child survival in Bangladesh: scale, speed, and selectivity in health and development.

    Adams, Alayne M; Rabbani, Atonu; Ahmed, Shamim; Mahmood, Shehrin Shaila; Al-Sabir, Ahmed; Rashid, Sabina F; Evans, Timothy G


    By disaggregating gains in child health in Bangladesh over the past several decades, significant improvements in gender and socioeconomic inequities have been revealed. With the use of a social determinants of health approach, key features of the country's development experience can be identified that help explain its unexpected health trajectory. The systematic equity orientation of health and socioeconomic development in Bangladesh, and the implementation attributes of scale, speed, and selectivity, have been important drivers of health improvement. Despite this impressive pro-equity trajectory, there remain significant residual inequities in survival of girls and lower wealth quintiles as well as a host of new health and development challenges such as urbanisation, chronic disease, and climate change. Further progress in sustaining and enhancing equity-oriented achievements in health hinges on stronger governance and longer-term systems thinking regarding how to effectively promote inclusive and equitable development within and beyond the health system.

    Conceived in 2003 and born in 2005 with the launch of its first report and country profiles, the Countdown to 2015 for Maternal, Newborn, and Child Survival has reached its originally proposed lifespan. Major reductions in the deaths of mothers and children have occurred since Countdown's inception, even though most of the 75 priority countries failed to achieve Millennium Development Goals 4 and 5. The coverage of life-saving interventions tracked in Countdown increased steadily over time, but wide inequalities persist between and within countries. Key drivers of coverage such as financing, human resources, commodities, and conducive health policies also showed important, yet insufficient increases. As a multistakeholder initiative of more than 40 academic, international, bilateral, and civil society institutions, Countdown was successful in monitoring progress and raising the visibility of the health of mothers, newborns, and children. Lessons learned from this initiative have direct bearing on monitoring progress during the Sustainable Development Goals era. PMID:26477328

  5. Barriers to accessing health care in Nigeria: implications for child survival

    Sunday A. Adedini


    Full Text Available Background: Existing studies indicate that about one in every six children dies before age five in Nigeria. While evidence suggests that improved access to adequate health care holds great potential for improved child survival, previous studies indicate that there are substantial barriers to accessing health care in Nigeria. There has not been a systematic attempt to examine the effects of barriers to health care on under-five mortality in Nigeria. This study is designed to address this knowledge gap. Data and method: Data came from a nationally representative sample of 18,028 women (aged 15–49 who had a total of 28,647 live births within the 5 years preceding the 2008 Nigeria Demographic and Health Survey. The risk of death in children below age five was estimated using Cox proportional hazard models and results are presented as hazards ratios (HR with 95% confidence intervals (CI. Results: Results indicate higher under-five mortality risks for children whose mothers had cultural barriers and children whose mothers had resource-related barriers to health care (HR: 1.44, CI: 1.32–1.57, p<0.001, and those whose mothers had physical barriers (HR: 1.13, CI: 1.04–1.24, p<0.001, relative to children whose mothers reported no barriers. Barriers to health care remained an important predictor of child survival even after adjusting for the effects of possible confounders. Conclusion: Findings of this study stressed the need for improved access to adequate health care in Nigeria through the elimination of barriers to access. This would enable the country to achieve a significant reduction in childhood mortality.

  6. Child mortality in rural Malawi: HIV closes the survival gap between the socio-economic strata.

    Andreas Jahn

    Full Text Available BACKGROUND: As HIV-related deaths increase in a population the usual association between low socioeconomic status and child mortality may change, particularly as death rates from other causes decline. METHODS/PRINCIPAL FINDINGS: As part of a demographic surveillance system in northern Malawi in 2002-6, covering a population of 32,000, information was collected on socio-economic status of the households. Deaths were classified as HIV/AIDS-related or not by verbal autopsy. Poisson regression models were used to assess the association of socio-economic indicators with all-cause mortality, AIDS-mortality and non-AIDS mortality among children. There were 195 deaths in infants, 109 in children aged 1-4 years, and 38 in children aged 5-15. All-cause child mortality in infants and 1-4 year olds was similar in households with higher and lower socio-economic status. In infants 13% of deaths were attributed to AIDS, and there were no clear trends with socio-economic status for AIDS or non-AIDS causes. For 1-4 year olds 27% of deaths were attributed to AIDS. AIDS mortality was higher among those with better built houses, and lowest in those with income from farming and fishing, whereas non-AIDS mortality was higher in those with worse built houses, lowest in those with income from employment, and decreased with increasing household assets. CONCLUSIONS/SIGNIFICANCE: In this population, since HIV infection among adults was initially more common among the less poor, childhood mortality patterns have changed. The usual gap in survival between the poor and the less poor has been lost, but because the less poor have been disproportionately affected by HIV, rather than because of relative improvement in the survival of the poorest.

  7. Global cost of child survival: estimates from country-level validation

    Liselore van Ekdom


    Full Text Available OBJECTIVE: To cross-validate the global cost of scaling up child survival interventions to achieve the fourth Millennium Development Goal (MDG4 as estimated by the World Health Organization (WHO in 2007 by using the latest country-provided data and new assumptions. METHODS: After the main cost categories for each country were identified, validation questionnaires were sent to 32 countries with high child mortality. Publicly available estimates for disease incidence, intervention coverage, prices and resources for individual-level and programme-level activities were validated against local data. Nine updates to the 2007 WHO model were generated using revised assumptions. Finally, estimates were extrapolated to 75 countries and combined with cost estimates for immunization and malaria programmes and for programmes for the prevention of mother-to-child transmission of the human immunodeficiency virus (HIV. FINDINGS: Twenty-six countries responded. Adjustments were largest for system- and programme-level data and smallest for patient data. Country-level validation caused a 53% increase in original cost estimates (i.e. 9 billion 2004 United States dollars [US$] for 26 countries owing to revised system and programme assumptions, especially surrounding community health worker costs. The additional effect of updated population figures was small; updated epidemiologic figures increased costs by US$ 4 billion (+15%. New unit prices in the 26 countries that provided data increased estimates by US$ 4.3 billion (+16%. Extrapolation to 75 countries increased the original price estimate by US$ 33 billion (+80% for 2010-2015. CONCLUSION: Country-level validation had a significant effect on the cost estimate. Price adaptations and programme-related assumptions contributed substantially. An additional 74 billion US$ 2005 (representing a 12% increase in total health expenditure would be needed between 2010 and 2015. Given resource constraints, countries will need

  8. [Changes in the conditions for child survival in Mexico and strategies for the future].

    Stern, C; Núñez, R M; Tolbert, K; Cárdenas, V; Goodwin, M


    Conditions of infant and child survival in Mexico have improved considerably over the last 60 years. Infant mortality rates were reduced from more than 250 deaths per 1,000 infants born alive in 1929-1931, to a rate of less than 50 in the period 1982-1987, a figure which still places Mexico among the countries with a high infant mortality rate. Though improvements in the living conditions of the population have undoubtedly played a part in the reduction of infant and child mortality, the early introduction of sanitation campaigns and, more recently of immunization, antibiotics and other modern health techniques have probably been more important. Health services have been extended throughout the country. However, significant portions of the population, especially in the rural areas, but also in the growing urban marginal ones, are to a large extent underserved. As a result, great inequalities in the health status of the population and in their access to health services remain. The problem of providing services to the whole population has become aggravated by the economic and financial crisis which has plagued Mexico since 1982. Reduced revenues for exports and the high cost of servicing the external and the internal debt have significantly decreased government revenues. As a result, public resources directed to health-related services diminished by 50 per cent in real terms between 1982 and 1987. This trend has to be reversed through enforced measures directed to the mobilization of untapped external and internal resources. But improving the conditions of child survival in Mexico requires more than financial resources. It is necessary to integrate and coordinate the fragmented services offered by the government, to give a much higher priority to preventive measures, and to research and to the adequate training of professionals and paraprofessionals in order to re-orient the health system for serving the real needs of the more underprivileged groups of the population

  9. Mediation Analysis with Survival Outcomes: Accelerated Failure Time Versus Proportional Hazards Models

    Lois A Gelfand


    Full Text Available Objective: Survival time is an important type of outcome variable in treatment research. Currently, limited guidance is available regarding performing mediation analyses with survival outcomes, which generally do not have normally distributed errors, and contain unobserved (censored events. We present considerations for choosing an approach, using a comparison of semi-parametric proportional hazards (PH and fully parametric accelerated failure time (AFT approaches for illustration.Method: We compare PH and AFT models and procedures in their integration into mediation models and review their ability to produce coefficients that estimate causal effects. Using simulation studies modeling Weibull-distributed survival times, we compare statistical properties of mediation analyses incorporating PH and AFT approaches (employing SAS procedures PHREG and LIFEREG, respectively under varied data conditions, some including censoring. A simulated data set illustrates the findings.Results: AFT models integrate more easily than PH models into mediation models. Furthermore, mediation analyses incorporating LIFEREG produce coefficients that can estimate causal effects, and demonstrate superior statistical properties. Censoring introduces bias in the coefficient estimate representing the treatment effect on outcome – underestimation in LIFEREG, and overestimation in PHREG. With LIFEREG, this bias can be addressed using an alternative estimate obtained from combining other coefficients, whereas this is not possible with PHREG.Conclusions: When Weibull assumptions are not violated, there are compelling advantages to using LIFEREG over PHREG for mediation analyses involving survival-time outcomes. Irrespective of the procedures used, the interpretation of coefficients, effects of censoring on coefficient estimates, and statistical properties should be taken into account when reporting results.

  10. Scope of health systems research in Child Survival and Safe Motherhood programme.

    Dutta, P K


    Editorial commentary focused on several Health System Research (HSR) approaches which exemplified some of the key issues for application of HSR for further improvement in Maternal and Child Health (MCH) services in India. The goals of HSR are to delineate health policy which improves the operations of the health care delivery system for sustainability at the district level. HSR is part of a global effort of Health For All by 2000 AD and India's Child Survival and Safe Motherhood (CSSM) program, sponsored by IDA/UNICEF. CSSM aims also to end polio by 2000 AD, eliminate neonatal tetanus by 1995, and prevent deaths and morbidity from measles, diarrheal diseases, and acute respiratory infection. MCH services will be expanded at the village, subcenter, primary health center, and community health center levels in order to reduce maternal mortality to below 2/1000 from the 1990 5/1000 and to reduce mortality of children aged 1-4 years to less than 10/1000 live births from 80/1000 by 2000 AD. States with particularly high levels of child and maternal mortality are Bihar, Uttar Pradesh, Rajasthan, and Madhya Pradesh, which have about 40% of India's population. These states have low marriage ages, low female literacy, and few women in nonagricultural employment. There are about 90 districts in these states with particularly low demographic indicators. India policy directs all CSSM work to be carried out by existing staff; the program emphasis will be training, supervision, and logistics. IEC will need to be directed to attitudinal change in rural areas and urban slums. Research has found that coverage is uneven and quality of MCH services, poor. One study will evaluate the performance over 5 years in Gwalior district in a nutrition and school health program. Another research effort will perform quality assessment of MCH care at the primary health care level and promote community awareness and increased utilization. An ongoing study is evaluating nationally the family welfare

  11. Systematic review of the effectiveness of mass media interventions for child survival in low- and middle-income countries.

    Naugle, Danielle A; Hornik, Robert C


    Through a systematic review of the literature, this article summarizes and evaluates evidence for the effectiveness of mass media interventions for child survival. To be included, studies had to describe a mass media intervention; address a child survival health topic; present quantitative data from a low- or middle-income country; use an evaluation design that compared outcomes using pre- and postintervention data, treatment versus comparison groups, or postintervention data across levels of exposure; and report a behavioral or health outcome. The 111 campaign evaluations that met the inclusion criteria included 15 diarrheal disease, 8 immunization, 2 malaria, 14 nutrition, 1 preventing mother-to-child transmission of HIV, 4 respiratory disease, and 67 reproductive health interventions. These evaluations were then sorted into weak (n = 33), moderate (n = 32), and stronger evaluations (n = 46) on the basis of the sampling method, the evaluation design, and efforts to address threats to inference of mass media effects. The moderate and stronger evaluations provide evidence that mass media-centric campaigns can positively impact a wide range of child survival health behaviors. PMID:25207453

    Bustreo, Flavia; Requejo, Jennifer Harris; Merialdi, Mario; Presern, Carole; Songane, Francisco


    The present paper provides an overview of the Safe Motherhood Initiative, Healthy Newborn Partnership, and Child Survival Partnership and their eventual merge into the Partnership for Maternal, Newborn and Child Health (PMNCH) in 2005. The promise and past successes of the PMNCH are highlighted, with a particular focus on the PMNCH's partner-centric approach showing the importance of collaboration for progress. The aims of the strategic framework for 2012-2015 are presented within the context of the Global Strategy for Women's and Children's Health, launched in 2010, and growing political momentum to achieve Millennium Development Goals 4 and 5 (reduce child mortality and improve maternal health, respectively). The next 4 years leading to 2015 are critical, and the global community must continue to work together to ensure all women and children are reached with key interventions proven to reduce mortality.

  14. Mothers’ Reading Skills and Child Survival in Nigeria: Examining the Relevance of Mothers’ Decision-Making Power

    Smith-Greenaway, Emily


    Mothers’ literacy skills are emerging as a key determinant of children’s health and survival in low-income contexts, with emphasis on the cognitive and psychological agency that literacy skills provide. This work has clearly established a strong association between mothers’ reading skills—a key subcomponent of broader literacy and language skills—and child mortality. However, this relatively nascent literature has not yet considered how broader social structures condition the process. In Nige...

  15. The comparative cost-effectiveness of an equity-focused approach to child survival, health, and nutrition: a modelling approach.

    Progress on child mortality and undernutrition has seen widening inequities and a concentration of child deaths and undernutrition in the most deprived communities, threatening the achievement of the Millennium Development Goals. Conversely, a series of recent process and technological innovations have provided effective and efficient options to reach the most deprived populations. These trends raise the possibility that the perceived trade-off between equity and efficiency no longer applies for child health--that prioritising services for the poorest and most marginalised is now more effective and cost effective than mainstream approaches. We tested this hypothesis with a mathematical-modelling approach by comparing the cost-effectiveness in terms of child deaths and stunting events averted between two approaches (from 2011-15 in 14 countries and one province): an equity-focused approach that prioritises the most deprived communities, and a mainstream approach that is representative of current strategies. We combined some existing models, notably the Marginal Budgeting for Bottlenecks Toolkit and the Lives Saved Tool, to do our analysis. We showed that, with the same level of investment, disproportionately higher effects are possible by prioritising the poorest and most marginalised populations, for averting both child mortality and stunting. Our results suggest that an equity-focused approach could result in sharper decreases in child mortality and stunting and higher cost-effectiveness than mainstream approaches, while reducing inequities in effective intervention coverage, health outcomes, and out-of-pocket spending between the most and least deprived groups and geographic areas within countries. Our findings should be interpreted with caution due to uncertainties around some of the model parameters and baseline data. Further research is needed to address some of these gaps in the evidence base. Strategies for improving child nutrition and survival, however

Accordingly this category may be a target for programmes and activities to promote child welfare and family planning.

  17. Mate selection and its impact on female marriage age, pregnancy wastages, and first child survival in Tamil Nadu, India.

    Sureender, S; Prabakaran, B; Khan, A G


    Marriage in Indian society is a religious duty. Consanguineous marriage is common, where individuals prefer to marry within their clan (a unilateral kin group based on either matrilineal or patrilineal descent). Keeping in mind that this form of marriage has certain disadvantages for social and biological as well as demographic aspects of individuals and families, the present study examines the influence of mate selection (i.e., close relatives, distant relatives, not related) on female age at marriage, pregnancy wastages, and survival status of the first child. The study was designed based on the information collected on a sample size of 3,948 married women aged 13-49 in Tamil Nadu, India, by the National Family Health Survey (NFHS), 1992. Results suggest that 48 per cent of women in Tamil Nadu marry their relatives. This practice of marrying relatives is high in rural areas, among Hindus, Scheduled Castes/tribes, and illiterate women as compared to urban areas, among non-Hindus, non-SC/ST, and educated women, respectively. The bivariate analysis reveals that women marrying their close relatives had low age at marriage and experienced a higher per cent of pregnancy wastage and child loss (first child) as compared to those women marrying their distant relatives or nonrelatives. The result is found to be consistent even after controlling for selected background variables through multivariate techniques (applied separately for age at marriage, pregnancy wastages, and the survival status of first child). Hence, this study suggests that steps should be taken to inform people about the problems of marrying close relatives through appropriate IEC programs in Tamil Nadu. PMID:10085741

    Analyzing stability of particle motion in storage rings contributes to the general field of stability analysis in weakly nonlinear motion. A method which we call pseudo invariant estimation (PIE) is used to compute lower bounds on the survival time in circular accelerators. The pseudeo invariants needed for this approach are computed via nonlinear perturbative normal form theory and the required global maxima of the highly complicated multivariate functions could only be rigorously bound with an extension of interval arithmetic. The bounds on the survival times are large enough to the relevant; the same is true for the lower bounds on dynamical aperatures, which can be computed. The PIE method can lead to novel design criteria with the objective of maximizing the survival time. A major effort in the direction of rigourous predictions only makes sense if accurate models of accelerators are available. Fringe fields often have a significant influence on optical properties, but the computation of fringe-field maps by DA based integration is slower by several orders of magnitude than DA evaluation of the propagator for main-field maps. A novel computation of fringe-field effects called symplectic scaling (SYSCA) is introduced. It exploits the advantages of Lie transformations, generating functions, and scaling properties and is extremely accurate. The computation of fringe-field maps is typically made nearly two orders of magnitude faster. (orig.)

  19. Child Survival and the Fertility of Refugees in Rwanda after the Genocide

    Philip Verwimp; Jan Van Bavel


    In the 1960s and 1990s, internal strife in Rwanda has caused a mass flow of refugees into neighbouring countries. This paper explores the cumulated fertility of Rwandan refugee women and the survival of their children. To this end, we use a national survey covering 6420 former refugee and non-refugee households conducted between 1999 and 2001. The findings support old-age security theories of reproductive behaviour: refugee women had higher fertility but their children had lower survival chan...

  20. Effects of Birth Month on Child Health and Survival in Sub-Saharan Africa

    Dorélien, Audrey M.


    Birth month is broadly predictive of both under-five mortality rates and stunting throughout most of sub-Saharan Africa (SSA). Observed factors, such as mother's age at birth and educational status, are correlated with birth month but are not the main factors underlying the relationship between birth month and child health. Accounting for maternal selection via a fixed-effects model attenuates the relationship between birth month and health in many SSA countries. In the remaining countries, t...

  1. The post-2015 agenda: staying the course in maternal and child survival.

    Requejo, Jennifer Harris; Bhutta, Zulfiqar A


    In this article, we draw on available evidence from Countdown to 2015 and other sources to make the case for keeping women and children at the heart of the next development agenda that will replace the Millennium Development Goal (MDG) framework after 2015. We provide a status update on global progress in achieving MDGs 4 and 5, reduce child mortality and improve maternal health, respectively--showing that although considerable mortality reductions have been achieved, many more women's and children's lives can be saved every day through available, cost effective interventions. We describe key underlying determinants of poor maternal and child health outcomes and the need for well-coordinated, comprehensive approaches for addressing them such as introducing a combination of nutrition specific and sensitive interventions to reduce pervasive malnutrition, targeting interventions to the underserved to reduce inequities in access to care, and increasing women's social status through improved access to education and income-earning opportunities. In the wake of population momentum and emergencies such as the recent ebola outbreak and other humanitarian crises, health systems must be strengthened to be able to respond to these pressures. In conclusion, we underscore that the unfinished business of women's and children's health must be prioritized in the days ahead, and that ending preventable maternal and child deaths is not only a moral obligation but is achievable and essential to sustainable development moving forward.

  4. Effects of the introduction of new vaccines in Guinea-Bissau on vaccine coverage, vaccine timeliness, and child survival

    Fisker, Ane B; Hornshøj, Linda; Rodrigues, Amabelia;


    BACKGROUND: In 2008, the GAVI Alliance funded the introduction of new vaccines (including pentavalent diphtheria-tetanus-pertussis [DTP] plus hepatitis B and Haemophilus influenzae type b antigens) in Guinea-Bissau. The introduction was accompanied by increased vaccination outreach services and a...... more restrictive wastage policy, including only vaccinating children younger than 12 months. We assessed coverage of all vaccines in the Expanded Program on Immunizations before and after the new vaccines' introduction, and the implications on child survival. METHODS: This observational cohort study...... used data from the Bandim Health Project, which has monitored vaccination status and mortality in randomly selected village clusters in Guinea-Bissau since 1990. We assessed the change in vaccination coverage using cohort data from children born in 2007 and 2009; analysed the proportion of children who...

  5. Accelerating progress toward reducing child malnutrition in India: A concept for action

    von Braun, Joachim; Ruel, Marie; Gulati, Ashok


    "1. The facts: Child malnutrition in India India is home to 40 percent of the world's malnourished children and 35 percent of the developing world's low-birth-weight infants; every year 2.5 million children die in India, accounting for one in five deaths in the world. More than half of these deaths could be prevented if children were well nourished. India's progress in reducing child malnutrition has been slow. The prevalence of child malnutrition in India deviates further from the expected l...

    The full impact of a maternal death includes consequences faced by orphaned children. This analysis adds evidence to a literature on the magnitude of the association between a woman's death during or shortly after childbirth, and survival outcomes for her children. The Ifakara and Rufiji Health and Demographic Surveillance Sites in rural Tanzania conduct longitudinal, frequent data collection of key demographic events at the household level. Using a subset of the data from these sites (1996-2...

  8. Firm survival, uncertainty and Financial frictions: Is there a Financial uncertainty accelerator?

    Byrne, Joseph P.; Spaliara, Marina Eliza; Tsoukas, Serafeim


    Using a large panel of unquoted UK firms over the period 2000-09, we examine the impact of firm-specific uncertainty on corporate failures. In this context we also distinguish between firms which are likely to be more or less dependent on bank finance as well as public and non-public companies. Our results document a significant effect of uncertainty on firm survival. This link is found to be more potent during the recent financial crisis compared with tranquil periods. We also uncover signif...

    KA Attia; KC Ackoundou-N'guessan; AT N'dri-yoman; AK Mahassadi; E Messou; YF Bathaix; YH Kissi


    AIM: To compare the performance of the Child-Pugh-Turcott (CPT) score to that of the model for end-stage liver disease (MELD) score in predicting survival of a retrospective cohort of 172 Black African patients with cirrhosis on a short and mid-term basis.METHODS: Univariate and multivariate (Cox model)analyses were used to identify factors related to mortality. Relationship between the two scores was appreciated by calculating the correlation coefficient.The Kaplan Meier method and the log rank test were used to elaborate and compare survival respectively.The Areas Under the Curves were used to compare the performance between scores at 3, 6 and 12 mo.RESULTS: The study population comprised 172 patients, of which 68.9% were male. The mean age of the patient was 47.5 ± 13 years. Hepatitis B virus infection was the cause of cirrhosis in 70% of the cases.The overall mortality was 31.4% over 11 years of follow up. Independent factors significantly associated with mortality were: CPT score (HR = 3.3, 95% CI [1.7-6.2])(P 1.5 mg/dL versus serum creatine 21 vs MELD < 21). The area under the curves (AUC)that predict survival was 0.72 and 0.75 at 3 mo (P = 0.68),0.64 and 0.62 at 6 mo (P = 0.67), 0.69 and 0.64 at 12 mo (P = 0.38) respectively for the CPT score and the MELD score.CONCLUSION: The CPT score displays the same prognostic significance as does the MELD score in black African patients with cirrhosis. Moreover, its handling appears less cumbersome in clinical practice as compared to the latter.

  11. Temporal trends and gender differentials in causes of childhood deaths at Ballabgarh, India - Need for revisiting child survival strategies

    Krishnan Anand


    Full Text Available Abstract Background Relating Information on causes of deaths to implementation of health interventions provides vital information for program planning and evaluation. This paper from Ballabgarh Health and Demographic Surveillance System (HDSS site in north India looks at temporal trends and gender differentials in the causes of death among under-five children. Methods Data on causes of death for 1972-74, 1982-84, 1992-94, 2002-04 were taken from existing HDSS publications and database. Physicians’ assigned causes of death were based on narratives by lay health worker till 1994 and later by verbal autopsy. Cause Specific Mortality Fractions (CSMF and Cause Specific Mortality Rates (CSMR per 1000 live births were calculated for neonatal ( Results The CSMF of prematurity and sepsis was 32% and 17.6% during neonatal period in 2002-04. The share of infections in all childhood deaths decreased from 55.2% in 1972-74 to 43.6% in 2002-04. All major causes of mortality (malnutrition, diarrhea and acute lower respiratory infection except injuries showed a steep decline among children and seem to have plateued in last decade. Most of disease specific public health interventions were launched in mid eighties. . Girls reported significantly higher mortality rates for prematurity (RR 1.52; 95% CI 1.01-2.29; diarrhea (2.29; 1.59 – 3.29, and malnutrition (3.37; 2.05 – 5.53. Conclusions The findings of the study point out to the need to move away from disease-specific to a comprehensive approach and to address gender inequity in child survival through socio-behavioural approaches.

    Full Text Available Research question: What proportions of the ASHAs are performing according to the training they have received under the Comprehensive Child Survival Programme (CCSP? Objective: To analyze the ASHAs’ practice with respect to CCSP in related situations. Study design: Cross-sectional study. Study location: Chiraigaon Community Development Block, Varanasi Material and method: 173 out of the total 240 ASHAs (~72% in the selected Chiraigaon Community Development Block of Varanasi were randomly selected and interviewed using a pre-designed and pre-tested questionnaire pertinent to CCSP. Only the first response was recorded. Results: All the ASHAs interviewed claimed that the CCSP training has helped them perform better in the community. Ninety-eight percent of the ASHAs knew that a new born weighing >2.5 kgs at birth is considered to be normal. Only ~ 63% (109 of the ASHAs were found to be home-visiting such newborns as per the CCSP recommendation. The percentage was found to be just 43% for the properly scheduled home visits of LBW newborns. The difference was found to be statistically significant (p<0.001. Almost 80% ASHAs estimated that their average home visit spans for at least 30 minutes. Just about a third of the interviewees suggested that a baby should be bathed only after the first 6 days while one-third said that they advise massaging for the newborn only after the first week. ASHAs rarely used a thermometer to assess the baby’s temperature. Around 56% were confident about using a thermometer. Nearly 90% participants claimed of explaining about Kangaroo Mother Care to the parturient and/or family. Majority of the ASHAs (92% emphasized upon non-discontinuation of breast feeding for the baby during diarrhoeal episodes. However, only 44% revisited such babies. Conclusion: In most cases it is well evident that CCSP training has been taken up well by the ASHAs. The training may be refreshed.

  13. The effect of winning an Oscar Award on survival: Correcting for healthy performer survivor bias with a rank preserving structural accelerated failure time model

    Han, Xu; Small, Dylan S.; Foster, Dean P.; Patel, Vishal


    We study the causal effect of winning an Oscar Award on an actor or actress's survival. Does the increase in social rank from a performer winning an Oscar increase the performer's life expectancy? Previous studies of this issue have suffered from healthy performer survivor bias, that is, candidates who are healthier will be able to act in more films and have more chance to win Oscar Awards. To correct this bias, we adapt Robins' rank preserving structural accelerated failure time model and $g...

  14. Integrated Strategies to Address Maternal and Child Health and Survival in Low-Income Settings: Implications for Haiti.

    Bhutta, Zulfiqar A


    The Millennium Development Goals for improving maternal and child health globally were agreed on in 2000, and several monitoring and evaluation strategies were put in place, including "Countdown to 2015" for monitoring progress and intervention coverage to reach the goals. However, progress in achieving the goals has been slow, with only 13 of the 75 participating Countdown countries on track to reach the targets for reducing child mortality.An overview of child mortality rates in low-income countries is presented, followed by a discussion of evidenced-based interventions that can bridge the equity gaps in global health. Finally, comments are included on the companion article in this issue, "Addressing the Child and Maternal Mortality Crisis in Haiti through a Central Referral Hospital Providing Countrywide Care" (page 59), and what is needed for that new project to succeed.

  15. Assessing early access to care and child survival during a health system strengthening intervention in Mali: a repeated cross sectional survey.

    Ari D Johnson

    Full Text Available BACKGROUND: In 2012, 6.6 million children under age five died worldwide, most from diseases with known means of prevention and treatment. A delivery gap persists between well-validated methods for child survival and equitable, timely access to those methods. We measured early child health care access, morbidity, and mortality over the course of a health system strengthening model intervention in Yirimadjo, Mali. The intervention included Community Health Worker active case finding, user fee removal, infrastructure development, community mobilization, and prevention programming. METHODS AND FINDINGS: We conducted four household surveys using a cluster-based, population-weighted sampling methodology at baseline and at 12, 24, and 36 months. We defined our outcomes as the percentage of children initiating an effective antimalarial within 24 hours of symptom onset, the percentage of children reported to be febrile within the previous two weeks, and the under-five child mortality rate. We compared prevalence of febrile illness and treatment using chi-square statistics, and estimated and compared under-five mortality rates using Cox proportional hazard regression. There was a statistically significant difference in under-five mortality between the 2008 and 2011 surveys; in 2011, the hazard of under-five mortality in the intervention area was one tenth that of baseline (HR 0.10, p<0.0001. After three years of the intervention, the prevalence of febrile illness among children under five was significantly lower, from 38.2% at baseline to 23.3% in 2011 (PR = 0.61, p = 0.0009. The percentage of children starting an effective antimalarial within 24 hours of symptom onset was nearly twice that reported at baseline (PR = 1.89, p = 0.0195. CONCLUSIONS: Community-based health systems strengthening may facilitate early access to prevention and care and may provide a means for improving child survival.

  16. Therapeutic administration of recombinant human granulocyte colony-stimulating factor accelerates hemopoietic regeneration and enhances survival in a murine model of radiation-induced myelosuppression

    The primary cause of death after radiation exposure is infection resulting from myelosuppression. Because granulocytes play a critical role in host defense against infection and because granulocyte proliferation and differentiation are enhanced by granulocyte colony-stimulating factor (G-CSF), this agent was evaluated for the ability to accelerate hemopoietic regeneration and to enhance survival in irradiated mice. C3H/HeN mice were irradiated and G-CSF (2.5 micrograms/day, s.c.) or saline was administered on days 3-12, 1-12 or 0-12 post-irradiation. Bone marrow, splenic and peripheral blood cellularity, and bone marrow and splenic granulocyte-macrophage progenitor cell recoveries were evaluated in mice exposed to 6.5 Gy. Mice exposed to 8 Gy were evaluated for multipotent hemopoietic stem cell recovery (using endogenous spleen colony-forming units) and enhanced survival. Results demonstrated that therapeutic G-CSF (1) accelerates hemopoietic regeneration after radiation-induced myelosuppression, (2) enhances survival after potentially lethal irradiation and (3) is most effective when initiated 1 h following exposure

  17. Accelerated phase chronic myeloid leukemia: evaluation of clinical criteria as predictors of survival, major cytogenetic response and progression to blast phase

    Vanessa Fiorini Furtado


    Full Text Available BACKGROUND: Published criteria defining the accelerated phase in chronic myeloid leukemia are heterogeneous and little is known about predictors of poor outcome.METHODS: This is a retrospective study of 139 subjects in the accelerated phase of chronic myeloid leukemia treated with imatinib at a single center in Brazil. The objective was to identify risk factors for survival, major cytogenetic response and progression to blast phase in this population. The factors analyzed were: blasts 10-29%, basophils ≥ 20%, platelets > 1 × 106/µL or 1 × 105/µL in the peripheral blood, as well as clonal evolution, splenomegaly, hemoglobin 12 months (p-value = 0.030.CONCLUSION: These data indicate that patients with the above risk factors have a worse prognosis. This information can guide the therapy to be used.

  18. Linear Correlation Between Patient Survival and Decreased Percentage of Tumor [18F]Fluorodeoxyglucose Uptake for Late-Course Accelerated Hyperfractionated Radiotherapy for Esophageal Cancer

    Purpose: The aims of this trial were to study whether a decreased percentage of tumor fluorodeoxyglucose (FDG) uptake (%DeltaSUVmax) correlated with overall survival and local control times for patients with esophageal cancer and which patients would benefit from a late-course accelerated hyperfractionated (LCHF) radiation scheme. Methods and Materials: A total of 50 eligible patients with squamous esophageal cancer received positron-emission tomography examinations three times and were treated with the LCHF radiation scheme, with a dose of 68.4 Gy/41 fractions in 6.5 weeks. A %DeltaSUVmax value was calculated, and patients were stratified as highly radiosensitive (HR), moderately radiosensitive (MR), and low radiosensitivity (LR) according to %DeltaSUVmax values in the conventional fraction (CF) scheme. Then, a linear correlation was calculated between patients’ survival time and %DeltaSUVmax. Local control and overall survival rates were compared after stratification. Results: In the MR subgroup, there was no linear correlation between %DeltaSUVmax and the CF and LCHF schemes (correlation coefficient, R 0.05). In the other subgroups (HR and LR), %DeltaSUVmax values between the CF and LCHF schemes were correlated. Also, in the HR and LR subgroups, %DeltaSUVmax after radiation correlated with overall survival or local control rates (correlation coefficient, R >0.5, and p < 0.05). Three-year local control rates in the HR, MR, and LR subgroups were 100%, 81.5%, and 0%, respectively (p < 0.001). Also, 3-year overall survival rates were 92.4%, 58.8%, and 0% for HR, MR, and LR subgroups, respectively (p < 0.001). Conclusions: Postradiation %DeltaSUVmax was positively correlated with survival time for patients’ with esophageal cancer. Patients who benefited from LCHF schedules were those with a decrease of 30% to 60% in tumor FDG uptake after the completion of CF radiation.

  19. Effectiveness of surgery and individualized high-dose hyperfractionated accelerated radiotherapy on survival in clinical stage I non-small cell lung cancer. A propensity score matched analysis

    Background and purpose: Surgery is considered the treatment of choice for early-stage non-small cell lung cancer (NSCLC). Patients with poor pulmonary function or other comorbidities are treated with radiotherapy. The objective of this investigation is to compare the 3-year survival of two early-stage NSCLC populations treated in two different hospitals, either by surgical resection (lobectomy) or by individualized high-dose accelerated radiotherapy, after matching patients by propensity scoring analysis. Methods: A retrospective comparative study has been performed on two series of consecutive patients with cytohistological diagnosis of NSCLC, clinically staged IA by means of PET-scan (radiotherapy group) and pathologically staged IA (surgery group). Results: A total of 157 cases were initially selected for the analysis (110 operated and 47 treated by radiotherapy). Patients in the radiotherapy group were older, with higher comorbidity and lower FEV1% with 3-years probability of survival for operated patients higher than that found for patients treated by radiotherapy. After matching by propensity scoring (using age and FEV1%), differences disappear and 3-years probability of survival had no statistical differences. Conclusions: Although this is a non-randomized retrospective analysis, we have not found 3-years survival differences after matching cases between surgery and radiotherapy. Nevertheless, data presented here support the continuous investigation for non-surgical alternatives in this disease.

  20. The Ghana essential health interventions program: a plausibility trial of the impact of health systems strengthening on maternal & child survival

    Awoonor-williams, John Koku; Bawah, Ayaga A; Nyonator, Frank K; Asuru, Rofina; Oduro, Abraham; Ofosu, Anthony; Phillips, James F


    Background During the 1990s, researchers at the Navrongo Health Research Centre in northern Ghana developed a highly successful community health program. The keystone of the Navrongo approach was the deployment of nurses termed community health officers to village locations. A trial showed that, compared to areas relying on existing services alone, the approach reduced child mortality by half, maternal mortality by 40%, and fertility by nearly a birth — from a total fertility rate of 5.5 in o...

  1. Survived infancy but still vulnerable: spatial-temporal trends and risk factors for child mortality in the Agincourt rural sub-district, South Africa, 1992-2007

    Benn Sartorius


    Full Text Available Targeting of health interventions to poor children at highest risk of mortality are promising approaches for enhancing equity. Methods have emerged to accurately quantify excess risk and identify space-time disparities. This provides useful and detailed information for guiding policy. A spatio-temporal analysis was performed to identify risk factors associated with child (1-4 years mortality in the Agincourt sub-district, South Africa, to assess temporal changes in child mortality patterns within the study site between 1992 and 2007, and to produce all-cause and cause-specific mortality maps to identify high risk areas. Demographic, maternal, paternal and fertility-related factors, household mortality experience, distance to health care facility and socio-economic status were among the examined risk factors. The analysis was carried out by fitting a Bayesian discrete time Bernoulli survival geostatistical model using Markov chain Monte Carlo simulation. Bayesian kriging was used to produce mortality risk maps. Significant temporal increase in child mortality was observed due to the HIV epidemic. A distinct spatial risk pattern was observed with higher risk areas being concentrated in poorer settlements on the eastern part of the study area, largely inhabited by former Mozambican refugees. The major risk factors for childhood mortality, following multivariate adjustment, were mother’s death (especially when due to HIV and tuberculosis, greater number of children under 5 years living in the same household and winter season. This study demonstrates the use of Bayesian geostatistical models for accurately quantifying risk factors and producing maps of child mortality risk in a health and demographic surveillance system. According to the space-time analysis, the southeast and upper central regions of the site appear to have the highest mortality risk. The results inform policies to address health inequalities in the Agincourt sub-district and to

  3. Split Course Hyperfractionated Accelerated Radio-Chemotherapy (SCHARC) for patients with advanced head and neck cancer: Influence of protocol deviations and hemoglobin on overall survival, a retrospective analysis

    The advantage of hyperfractionated accelerated radiation therapy for advanced head and neck cancer has been reported. Furthermore, randomized trials and meta-analyses have confirmed the survival benefit of additional chemotherapy to radiotherapy. We retrospectively analyzed the efficiency and toxicity of the Regensburg standard therapy protocol 'SCHARC' and the overall survival of our patients. From 1997 to 2004, 64 patients suffering from advanced head and neck cancer (88 % stage IV, 12 % stage III) were assigned to receive the SCHARC protocol. Around half of the patients were diagnosed with oro-hypopharynx carcinoma (52 %), one third with tongue and floor of mouth tumors (29 %) and one fifth (19 %) suffered from H & N cancer at other sites. The schedule consisted of one therapy block with 30 Gy in 20 fractions over a two week period with concomitant chemotherapy (d 1–5: 20 mg/m2/d DDP + 750–1000 mg/m2/d 5FU (cont. infusion). This therapy block was repeated after a fortnight break up to a cumulative dose of 60 Gy and followed by a boost up to 70 Gy (69–70.5 Gy). All patients assigned to this scheme were included in the survival evaluation. Forty patients (63 %) received both radiation and chemotherapy according to the protocol. The mean follow up was 2.3 years (829 d) and the median follow up was 1.9 years (678 d), respectively. The analysis of survival revealed an estimated 3 year overall survival rate of 57 %. No patient died of complications, 52 patients (80 %) had acute grade 2–3 mucositis, and 33 patients (58 %) suffered from acute grade 3 skin toxicity. Leucopenia was no major problem (mean nadir 3.4 g/nl, no patient < 1.0 g/nl) and the mean hemoglobin value decreased from 13.2 to 10.5 g/dl. Univariate analysis of survival showed a better outcome for patients with a hemoglobin nadir >10.5 g/dl and for patients who completed the protocol. The SCHARC protocol was effective in patients diagnosed with advanced head and neck cancer. It led to

    We present a large-scale social marketing programme of insecticide-treated nets in 2 rural districts in southwestern Tanzania (population 350,000) and describe how the long-term child health and survival impact will be assessed. Formative and market research were conducted in order to understand community perceptions, knowledge, attitudes and practice with respect to the products to be socially marketed. We identified Zuia Mbu (Kiswahili for 'prevent mosquitoes') as a suitable brand name for both treated nets and single-dose insecticide treatment sachets. A mix of public and private sales outlets is used for distribution. In the first stage of a stepped introduction 31 net agents were appointed and trained in 18 villages: 15 were shop owners, 14 were village leaders, 1 was a parish priest and 1 a health worker. For net treatment 37 young people were appointed in the same villages and trained as agents. Further institutions in both districts such as hospitals, development projects and employers were also involved in distribution. Promotion for both products was intense and used a variety of channels. A total of 22,410 nets and 8072 treatments were sold during the first year: 18 months after launching, 46% of 312 families with children aged under 5 years reported that their children were sleeping under treated nets. A strong evaluation component in over 50,000 people allows assessment of the long-term effects of insecticide-treated nets on child health and survival, anaemia in pregnancy, and the costs of the intervention.

    Higgs, Elizabeth S; Goldberg, Allison B; Labrique, Alain B; Cook, Stephanie H; Schmid, Carina; Cole, Charlotte F; Obregón, Rafael A


    Given the high morbidity and mortality among children in low- and middle-income countries as a result of preventable causes, the U.S. government and the United Nations Children's Fund convened an Evidence Summit on Enhancing Child Survival and Development in Lower- and Middle-Income Countries by Achieving Population-Level Behavior Change on June 3-4, 2013, in Washington, D.C. This article summarizes evidence for technological advances associated with population-level behavior changes necessary to advance child survival and healthy development in children under 5 years of age in low- and middle-income countries. After a rigorous evidence selection process, the authors assessed science, technology, and innovation papers that used mHealth, social/transmedia, multiplatform media, health literacy, and devices for behavior changes supporting child survival and development. Because of an insufficient number of studies on health literacy and devices that supported causal attribution of interventions to outcomes, the review focused on mHealth, social/transmedia, and multiplatform media. Overall, this review found that some mHealth interventions have sufficient evidence to make topic-specific recommendations for broader implementation, scaling, and next research steps (e.g., adherence to HIV/AIDS antiretroviral therapy, uptake and demand of maternal health service, and compliance with malaria treatment guidelines). While some media evidence demonstrates effectiveness in changing cognitive abilities, knowledge, and attitudes, evidence is minimal on behavioral endpoints linked to child survival. Population level behavior change is necessary to end preventable child deaths. Donors and low- and middle-income countries are encouraged to implement recommendations for informing practice, policy, and research decisions to fully maximize the impact potential of mHealth and multimedia for child survival and development.

  6. Evaluation of onion root tip cell surviving fraction by measuring growing speed irradiated by accelerated heavy ions

    Irradiation of accelerated heavy ions to germinated onion seeds reduced the root growth. The extent of the root shortening increased with the increase of the absorbed dose and with the increase of linear energy transfer (LET). The growing curve looks like converging to a limited curve with increase of the dose and the growing did not stop even at highest dose of 100 Gy. Germinated seeds of green sorgo and alphalfa were investigated for comparison and they showed different dose responses from onion. Growth of green sorgo germs almost stopped at high doses. Growth of alphalfa germs was unaffected by radiations. (author)

  7. Evaluation of onion root tip cell surviving fraction by measuring growing speed irradiated by accelerated heavy ions

    Average growth of germinating onion seed roots irradiated with accelerated heavy ions decreased with increase of absorbed dose, and the ratio to the non-irradiated seeds approached asymptotically to about 40% with increasing of the dose and almost converged at 10 Gy. The converged ratio was about 20% for green sorgo seeds and about 80% for alphalfa seeds. Irradiation of the heavy ions and γ-ray larger than 2 Gy delayed appearance of micronuclei in the onion root tip cells. The delay increased with the increase of linear energy transfer (LET) and absorbed dose. (author)

  8. The Saturation+ Approach to Behavior Change: Case Study of a Child Survival Radio Campaign in Burkina Faso.

    Murray, Joanna; Remes, Pieter; Ilboudo, Rita; Belem, Mireille; Salouka, Souleymane; Snell, Will; Wood, Cathryn; Lavoie, Matthew; Deboise, Laurent; Head, Roy


    A 35-month cluster randomized controlled trial was conducted in Burkina Faso to test whether a radio campaign focused on child health, broadcast between March 2012 and January 2015, could reduce under-5 mortality. This paper describes the design and implementation of the mass media intervention in detail, including the Saturation+ principles that underpinned the approach, the creative process, the lessons learned, and recommendations for implementing this intervention at scale. The Saturation+ approach focuses on the 3 core principles of saturation (ensuring high exposure to campaign messages), science (basing campaign design on data and modeling), and stories (focusing the dramatic climax on the target behavior) to maximize the impact of behavior change campaigns. In Burkina Faso, creative partnerships with local radio stations helped us obtain free airtime in exchange for training and investing in alternative energy supplies to solve frequent energy problems faced by the stations. The campaign used both short spots and longer drama formats, but we consider the short spots as a higher priority to retain during scale-up, as they are more cost-effective than longer formats and have the potential to ensure higher exposure of the population to the messages. The implementation research synthesized in this paper is designed to enable the effective adoption and integration of evidence-based behavior change communication interventions into health care policy and practice.

  9. The Economics of Child Trafficking

    Sylvain Dessy; Stéphane Pallage


    In this paper, we highlight the economic effects of the existence of child trafficking. We show that the risk of child trafficking on the labor market acts as a deterrent to supply child labor, unless household survival is at stake. An imperfectly enforceable legislation aiming at fighting child trafficking, by raising the expected gains parents derive from sending their children to work, will cause a rise in the number of child laborers. We show that it can even cause the incidence of child ...

  10. New trends in under-five mortality determinants and their effects on child survival in Nigeria: A review of childhood mortality data from 1990-2008

    Joshua O. Akinyemi


    Full Text Available Under-five mortality in Nigeria has been reported to be on the decline, but the dynamics are yet to receiveadequate attention. Thus the main objective of this study was to assess these factors and quantify their relativecontributions to under-five mortality between 1990 and 2008. The Nigeria Demographic and HealthSurvey data for 1990, 2003 and 2008 were re-analysed to assess the trends in determinants of under-fivemortality.Cox Regression model was applied to determine the relative contributions of each factor to theunder-five mortality risk.The results showed there were improvements in maternal education (8.6%, childhoodvaccination (17.7%, use of oral rehydration therapy (13.9% and medical treatment of childhood illnesses(17.5% over the 19-year period. There were declines in proportions with birth interval less than 24months (3.9%, access to improved sources of drinking water (24.2%, improved toilet facilities (9.0%antenatal care (4.5%, skilled delivery (3.0% while maternal age at childbirth remained unchanged. Thesefactors increased the death hazards by 4.6% between 1990-2003 but decreased them by 12% between2003 and 2008. It was concluded that Nigeria has recorded very minimal improvements in birth spacing andantenatal/delivery care. Poor access to potable drinking water and sewage disposal, and short birth intervals,are among the factors fuelling childhood mortality risks. Further improvements in these environmental andhealth practices as well as other factors are recommended as strategies for promoting child survival inNigeria.

  11. Anticancer compound ABT-263 accelerates apoptosis in virus-infected cells and imbalances cytokine production and lowers survival rates of infected mice.

    Kakkola, L; Denisova, O V; Tynell, J; Viiliäinen, J; Ysenbaert, T; Matos, R C; Nagaraj, A; Ohman, T; Kuivanen, S; Paavilainen, H; Feng, L; Yadav, B; Julkunen, I; Vapalahti, O; Hukkanen, V; Stenman, J; Aittokallio, T; Verschuren, E W; Ojala, P M; Nyman, T; Saelens, X; Dzeyk, K; Kainov, D E


    ABT-263 and its structural analogues ABT-199 and ABT-737 inhibit B-cell lymphoma 2 (Bcl-2), BCL2L1 long isoform (Bcl-xL) and BCL2L2 (Bcl-w) proteins and promote cancer cell death. Here, we show that at non-cytotoxic concentrations, these small molecules accelerate the deaths of non-cancerous cells infected with influenza A virus (IAV) or other viruses. In particular, we demonstrate that ABT-263 altered Bcl-xL interactions with Bcl-2 antagonist of cell death (Bad), Bcl-2-associated X protein (Bax), uveal autoantigen with coiled-coil domains and ankyrin repeats protein (UACA). ABT-263 thereby activated the caspase-9-mediated mitochondria-initiated apoptosis pathway, which, together with the IAV-initiated caspase-8-mediated apoptosis pathway, triggered the deaths of IAV-infected cells. Our results also indicate that Bcl-xL, Bcl-2 and Bcl-w interact with pattern recognition receptors (PRRs) that sense virus constituents to regulate cellular apoptosis. Importantly, premature killing of IAV-infected cells by ABT-263 attenuated the production of key pro-inflammatory and antiviral cytokines. The imbalance in cytokine production was also observed in ABT-263-treated IAV-infected mice, which resulted in an inability of the immune system to clear the virus and eventually lowered the survival rates of infected animals. Thus, the results suggest that the chemical inhibition of Bcl-xL, Bcl-2 and Bcl-w could potentially be hazardous for cancer patients with viral infections. PMID:23887633

  12. Child Labor - Moral Choice

    Lagasse, Caitlin


    In many instances, child labor is a way to exploit the cheap labor a child has to offer. Although in many situations, the exploitation of child labor is not normally the case, such as families living in a developing country. What individuals raised in Western cultures fail to realize is that in some nations and for some families, child labor is a necessary resource to survive, children act as an exceptional resource in these situations. Without the extra income a child could make working in t...

  16. Maternal knowledge on child survival in the poorest areas of North and Northeast Brazil: o caso de áreas pobres nas regiões Norte e Nordeste do Brasil Conhecimento materno em sobrevivência infantil

    Juraci A. Cesar


    Full Text Available This study aimed to evaluate knowledge on child survival among mothers of children under five years of age living in nine municipalities in North and Northeast Brazil. A standardized questionnaire was used for home interviews of mothers visited by volunteers from the Pastorate of the Child and mothers not visited by the program (control areas. The association between independent variables and the outcome (visited versus not visited by the Pastorate of the Child was evaluated using the chi-square test. Among the 752 mothers studied, 386 were visited by Pastorate of the Child volunteers and 366 were not visited. Mothers visited by the Pastorate of the Child, although poorer, showed better knowledge on monitoring child growth and identifying child development difficulties as compared to mothers from the control areas. Despite the better performance of mothers visited by the Pastorate of the Child volunteers, maternal knowledge on child survival in both groups was less than desirable. This hinders the identification of more serious cases, delays seeking medical care, and reduces the impact on child morbidity and mortality.Este estudo teve por objetivo avaliar o conhecimento em sobrevivência infantil entre mães de menores de cinco anos residentes em nove municípios das regiões Norte e Nordeste do Brasil. Aplicou-se questionário padronizado no domicílio para mães acompanhadas pelos líderes da Pastoral da Criança e não acompanhadas (áreas-controle. A associação entre as variáveis independentes e o desfecho (receber ou não visita dos líderes da Pastoral da Criança foi avaliada pelo teste do qui-quadrado. Dentre as 752 mães estudadas, 386 eram visitadas pelos líderes da Pastoral da Criança e 366 não eram visitadas. Mães visitadas pelos líderes da Pastoral da Criança, apesar de mais pobres, apresentaram melhor conhecimento sobre monitoração do crescimento infantil, identificação de pneumonia e dificuldade no desenvolvimento em

  17. The EPICS Trial: Enabling Parents to Increase Child Survival through the introduction of community-based health interventions in rural Guinea Bissau

    Frost Chris


    Full Text Available Abstract Background Guinea-Bissau is a small country in West Africa with a population of 1.7 million. The WHO and UNICEF reported an under-five child mortality of 203 per 1000, the 10th highest amongst 192 countries. The aim of the trial is to assess whether an intervention package that includes community health promotion campaign and education through health clubs, intensive training and mentoring of village health workers to diagnose and provide first-line treatment for children's diseases within the community, and improved outreach services can generate a rapid and cost-effective reduction in under-five child mortality in rural regions of Guinea-Bissau. Effective Intervention plans to expand the project to a much larger region if there is good evidence after two and a half years that the project is generating a cost-effective, sustainable reduction in child mortality. Methods/design This trial is a cluster-randomised controlled trial involving 146 clusters. The trial will run for 2.5 years. The interventions will be introduced in two stages: seventy-three clusters will receive the interventions at the start of the project, and seventy-three control clusters will receive the interventions 2.5 years after the first clusters have received all interventions if the research shows that the interventions are effective. The impact of the interventions and cost-effectiveness will be measured during the first stage. The package of interventions includes a community health promotion campaign and education through health clubs, and intensive training and mentoring of village health workers to diagnose and provide first-line treatment for common children's diseases within the community. It also includes improved outreach services to encourage provision of antenatal and post natal care and provide ongoing monitoring for village health workers. The primary outcome of the trial will be the proportion of children that die under 5 years of age during the trial

  18. Partner testing, linkage to care, and HIV-free survival in a program to prevent parent-to-child transmission of HIV in the Highlands of Papua New Guinea

    Andy Carmone


    Full Text Available Background: To eliminate new pediatric HIV infections, interventions that facilitate adherence, including those that minimize stigma, enhance social support, and mitigate the influence of poverty, will likely be required in addition to combination antiretroviral therapy (ART. We examined the relationship between partner testing and infant outcome in a prevention of parent-to-child transmission of HIV program, which included a family-centered case management approach and a supportive environment for partner disclosure and testing. Design: We analyzed routinely collected data for women and infants who enrolled in the parent-to-child transmission of HIV program at Goroka Family Clinic, Eastern Highlands Provincial Hospital, Papua New Guinea, from 2007 through 2011. Results: Two hundred and sixty five women were included for analysis. Of these, 226 (85% had a partner, 127 (56% of whom had a documented HIV test. Of the 102 HIV-infected partners, 81 (79% had been linked to care. In adjusted analyses, we found a significantly higher risk of infant death, infant HIV infection, or loss to follow-up among mother–infant pairs in which the mother reported having no partner or a partner who was not tested or had an unknown testing status. In a second multivariable analysis, infants born to women with more time on ART or who enrolled in the program in later years experienced greater HIV-free survival. Conclusions: In a program with a patient-oriented and family-centered approach to prevent vertical HIV transmission, the majority of women's partners had a documented HIV test and, if positive, linkage to care. Having a tested partner was associated with program retention and HIV-free survival for infants. Programs aiming to facilitate diagnosis disclosure, partner testing, and linkage to care may contribute importantly to the elimination of pediatric HIV.

  20. A High-Fat Diet Containing Lard Accelerates Prostate Cancer Progression and Reduces Survival Rate in Mice: Possible Contribution of Adipose Tissue-Derived Cytokines

    Han Jin Cho


    Full Text Available To examine the effects of high-fat diet (HFD containing lard on prostate cancer development and progression and its underlying mechanisms, transgenic adenocarcinoma mouse prostate (TRAMP and TRAMP-C2 allograft models, as well as in vitro culture models, were employed. In TRAMP mice, HFD feeding increased the incidence of poorly differentiated carcinoma and decreased that of prostatic intraepithelial neoplasia in the dorsolateral lobes of the prostate, which was accompanied by increased expression of proteins associated with proliferation and angiogenesis. HFD feeding also led to increased metastasis and decreased survival rate in TRAMP mice. In the allograft model, HFD increased solid tumor growth, the expression of proteins related to proliferation/angiogenesis, the number of lipid vacuoles in tumor tissues, and levels of several cytokines in serum and adipose tissue. In vitro results revealed that adipose tissue-conditioned media from HFD-fed mice stimulated the proliferation and migration of prostate cancer cells and angiogenesis compared to those from control-diet-fed mice. These results indicate that the increase of adipose tissue-derived soluble factors by HFD feeding plays a role in the growth and metastasis of prostate cancer via endocrine and paracrine mechanisms. These results provide evidence that a HFD containing lard increases prostate cancer development and progression, thereby reducing the survival rate.

  1. The battered child syndrome

    The recognition of a battered child represents a challenge for all groups of adults dealing with children. Radiology plays a special role in this setting. By detection typical injuries, imaging is able to confirm the suspicion of a battered child. Recognition of those injuries on films, taken for other reasons, gives the caretaker an important hint, thus maybe preventing a fatal outcome for the child. One of the most important injury types is represented by the so called ''shakin baby syndrome''. The infant is held by the thorax and shaken. Thus causing a repetitive acceleration-deceleration trauma, which leads to the typical paravertebral rib fractures, intracranial bleeding and eye injuries. After shaking the child is thrown away, with subsequent injuries. The aim of this article is the presentation of an overview regarding the radiology of the battered child. Typical examples will be shown. (orig.)

  2. Aumento de la sobrevida en menores de cinco años en México: la estrategia diagonal Improvement of child survival in Mexico: the diagonal approach

    Jaime Sepúlveda


    de las políticas de salud pública junto con el reforzamiento de la infraestructura institucional también contribuyen a explicar la reducción en las tasas de mortalidad en menores de cinco años.Public health interventions aimed at children in Mexico have placed the country among the seven countries on track to achieve the goal of child mortality reduction by 2015. We analysed census data, mortality registries, the nominal registry of children, national nutrition surveys, and explored temporal association and biological plausibility to explain the reduction of child, infant, and neonatal mortality rates. During the past 25 years, child mortality rates declined from 64 to 23 per 1000 livebirths. A dramatic decline in diarrhoea mortality rates was recorded. Polio, diphtheria, and measles were eliminated. Nutritional status of children improved significantly for wasting, stunting, and underweight. A selection of highly cost-effective interventions bridging clinics and homes, what we called the diagonal approach, were central to this progress. Although a causal link to the reduction of child mortality was not possible to establish, we saw evidence of temporal association and biological plausibility to the high level of coverage of public health interventions, as well as significant association to the investments in women education, social protection, water, and sanitation. Leadership and continuity of public health policies, along with investments on institutions and human resources strengthening, were also among the reasons for these achievements.

    This paper investigates whether the income from child wage work is necessary to the survival of rural households in Pakistan. It is by no means obvious that it is. For instance, children may work because the returns to work exceed the returns to school, or because parents are selfish or short-sighted. It is argued here that, if child work is necessary, then the income effect of a wage change will dominate the substitution effect and the labour supply curve will be "forward falling" or negativ...

  11. Statistical Analysis of Factors Affecting Child Mortality in Pakistan.

    Ahmed, Zoya; Kamal, Asifa; Kamal, Asma


    Child mortality is a composite indicator reflecting economic, social, environmental, healthcare services, and their delivery situation in a country. Globally, Pakistan has the third highest burden of fetal, maternal, and child mortality. Factors affecting child mortality in Pakistan are investigated by using Binary Logistic Regression Analysis. Region, education of mother, birth order, preceding birth interval (the period between the previous child birth and the index child birth), size of child at birth, and breastfeeding and family size were found to be significantly important with child mortality in Pakistan. Child mortality decreased as level of mother's education, preceding birth interval, size of child at birth, and family size increased. Child mortality was found to be significantly higher in Balochistan as compared to other regions. Child mortality was low for low birth orders. Child survival was significantly higher for children who were breastfed as compared to those who were not. PMID:27354000

  4. Induction accelerators

    Takayama, Ken


    A broad class of accelerators rests on the induction principle whereby the accelerating electrical fields are generated by time-varying magnetic fluxes. Particularly suitable for the transport of bright and high-intensity beams of electrons, protons or heavy ions in any geometry (linear or circular) the research and development of induction accelerators is a thriving subfield of accelerator physics. This text is the first comprehensive account of both the fundamentals and the state of the art about the modern conceptual design and implementation of such devices. Accordingly, the first part of the book is devoted to the essential features of and key technologies used for induction accelerators at a level suitable for postgraduate students and newcomers to the field. Subsequent chapters deal with more specialized and advanced topics.

    In recent years, there has been an astonishing proliferation of empirical work on child labor. An Econlit search of keywords "child lab*r" reveals a total of 6 peer reviewed journal articles between 1980 and 1990, 65 between 1990 and 2000, and 143 in the first five years of the present decade. The purpose of this essay is to provide a detailed overview of the state of the recent empirical literature on why and how children work as well as the consequences of that work.

  7. Child abuse

    Child abuse is common in most, if not all, Western nations; it probably occurs worldwide. It may be a major factor in the increase in violence throughout much of the world. Radiologists who treat children should think of the possibilitys of abuse whenever they diagnose a fracture, intracranial bleed, ar visceral injury, especially when the history is not compatible with their findings. Metaphyseal 'corner' fractures in infants usually are caused by abuse. Less than 20% of abused children, however, present injuries that can be recognized by radiologic techniques. Consequently normal roentgenograms, nuclear medicine scans, ultrasound studies, and computed tomograms do not exclude child abuse. (orig.)


    Human Resources Division


    HR Division wishes to clarify to members of the personnel that the allowance for a dependent child continues to be paid during all training courses ('stages'), apprenticeships, 'contrats de qualification', sandwich courses or other courses of similar nature. Any payment received for these training courses, including apprenticeships, is however deducted from the amount reimbursable as school fees. HR Division would also like to draw the attention of members of the personnel to the fact that any contract of employment will lead to the suppression of the child allowance and of the right to reimbursement of school fees.

  9. Child's right to special care.

    Sharma, A; Gupta, S


    In 1924, the League of Nations adopted the 1st international law recognizing that children have inalienable rights and are not the property of their father. The UN Declaration on the Rights of the Child emerged in 1959. 1979 was the International Year of the Child. In 1990 there was the World Summit on Children and the UN General Assembly adopted the Global Convention on the Rights of the Child. The convention included civil, economic, social, cultural, and political rights of children all of which covered survival, development, protection, and participation. At the end of 1990, 60 countries had ratified the convention, thus including it into their national legislation. Even though India had not yet endorsed the Convention by the end of 1991, it expressed its support during the 1st workshop on the Rights of the Child which focused on girls. India has a history of supporting children as evidenced by 250 central and state laws on their welfare such as child labor and child marriage laws. In 1974, India adopted the National Policy for Children followed by the establishment of the National Children's Board in 1975. The Board's activities resulted in the Integrated Child Development Services Program which continues to include nutrition, immunization, health care, preschool education, maternal education, family planning, and referral services. Despite these laws and actions, however, the Indian government has not been able to improve the status of children. For example, between 1947-88, infant mortality fell only from 100/1000 to 93/1000 live births and child mortality remained high at 33.3 in 1988 compared with 51.9 in 1971. Population growth poses the biggest problem to improving their welfare. Poverty also exacerbates their already low status. PMID:12317284

  10. Ensuring survival.

    Sadik, N


    The global population growth rate has been 1.7% since 1975, while for developing countries it is 2.1%. UN projections are for population to grow from 5.5 billion in 1992 to 10 billion by 2050. Sustainable development is only possible when population growth is balanced with available resources. UN medium population projections of 7.8 billion by 2050 can be reached with 187 million more couples practicing family planning (FP) by the year 2000. Within the past 20 years, 1 billion people, mostly from developed countries, have enjoyed economic growth, but have contributed polluting technologies, excessive waste, and environmentally dangerous economic practices. The generations to come will be affected by the continuance of these practices by the 1 billion affluent population. The bottom billion are mired in poverty and high population growth and survival, needs that hinder their country's economic development, upset fragile ecosystems, and destroy the balance between human beings and the environment. International migration on a large scale could be the by-product of population growth. Progress has been made since the 1974 UN Conference on Population in Bucharest. There are still, however, vulnerable populations, the poorest households, the landless and small-holder families, urban squatters and slum dwellers, those living in low lying deltas and along coasts, and women. Women control family resources and their micro environment. Sustainable development is not possible without the elimination of prejudice against women. Reproductive freedom for women must be a priority. High quality, readily available FP services are also needed for those desiring this. The difficulty is in providing FP services that conform to a woman's social and cultural background and personal needs; success is dependent on involving women in the process and holding men more responsible for FP. Development means allowing for the legitimate aspirations of the majority not just the specialized

  11. A Multidimensional Approach to Measuring Child Poverty

    Sharmila Kurukulasuriya; Solrun Engilbertsdottir


    There is a growing consensus that children experience poverty in ways that are different from adults; and looking at child poverty through an income-consumption lens only is inadequate. The 2005 State of the World’s Children presented the following definition of child poverty: “Children living in poverty experience deprivation of the material, spiritual and emotional resources needed to survive, develop and thrive, leaving them unable to enjoy their rights, achieve their full potential or par...

    Human trafficking is the third biggest beneficial industry on the planet. Child trafficking unlike many other issues is found in both developed and developing nations. NGOs evaluate that 12,000 - 50,000 ladies and kids are trafficked into the nation every year from neighboring states for the sex exchange.

  14. Causas do declínio acelerado da desnutrição infantil no Nordeste do Brasil (1986-1996-2006 Causas de la disminución acelerada de la desnutrición infantil en Noreste de Brasil (1986-1996-2006 Causes of the accelerated decline in child undernutrition in Northeastern Brazil (1986-1996-2006

    Ana Lucia Lovadino de Lima


    undernutrition fell by one-third between 1986 and 1996 (from 33.9% to 22.2% and by almost three-quarters between 1996 and 2006 (from 22.2% to 5.9%. Improvements in maternal schooling and in the coverage of water and sewage services were particularly important for the decline in child undernutrition in the first period, while increasing purchasing power of the poorest families and, again, maternal schooling were more relevant in the second period. CONCLUSIONS: The acceleration of the decline in child undernutrition between the two periods was consistent with accelerated improvement of maternal schooling, water supply and sewage, health care, and maternal reproductive antecedents, as well as with the outstanding increase in purchasing power among the poor during the second period. If the rate of decline in growth deficits is kept at around the rate of the most recent period, child undernutrition will be controlled in the Brazilian Northeast in less than ten years. Achieving this will depend on sustaining the increase in purchasing power among the poor and on ensuring public investment in completing the universalization of access to essential services such as education, health, and sanitation.

  15. Tandem accelerators

    After the installation of Ti-acceleration tubes and substantial modifications and additions to the EN tandem accelerator the performance of the machine has stabilized. The voltage behaviour of the tubes obviously improves as conditioning times necessary to run up to 6 MV decrease. A gridded lens has been added at the entrance of the first acceleration tube, and a second foil stripper is now installed in the short dead section between the high-energy tubes. The MP tandem also has been running stably during most of the year. However, beam instabilities originating from the last tube section and wear problems at the low-energy set of pelletron-chains caused some loss of beam time. During the fall, one set of pelletron charging chains has to be replaced after 49,000 hours of operation. In the course of the year, the MP and the EN tandem accelerators finished their 100,000th and 150,000th hours of operations, respectively. Preparations for the installation of the 3 MV negative heavy ion injector for the MP are progressing steadily. External beam transport, terminal ion optics, and data acquisition and control systems are to a major extent completed; the integration of the terminal power supplies has started. After the final assembly of the accelerator column structure, first voltage runs can be performed. (orig.)

  16. Child pornography

    Pavlović, Zoran S.; Petković, Nikola; Matijašević Obradović, Jelena


    The abuse of children for pornographic purposes is a serious sociological, criminological and victimological problem of today which, despite all preventive and restrictive activities on an international level, shows a tendency of global expansion. The fact that the Republic of Serbia has only recently actively joined the fight against child pornography on the Internet indicates the need for critical analysis of the existing national, penal, and legal solutions and their harmonization with the...

    The most neglected form of human deprivation is malnutrition particularly among preschool children. Millions of Indian children are equally deprived of the rights to survival, health, nutrition, education and safe drinking water. Interventions for preschool children (Early Childhood Care and Development) in India must be broadly addressed in three dimensions: child health, child development/education and child nutrition. The specific objectives of the study are to examine the current picture ...

    Charmian M. Bennett; Sharon Friel


    This paper addresses an often overlooked aspect of climate change impacts on child health: the amplification of existing child health inequities by climate change. Although the effects of climate change on child health will likely be negative, the distribution of these impacts across populations will be uneven. The burden of climate change-related ill-health will fall heavily on the world’s poorest and socially-disadvantaged children, who already have poor survival rates and low life expect...

  19. Philippine campaign boosts child immunizations.

    Manuel-santana, R


    In 1989, USAID awarded the Philippines a 5-year, US $50 million Child Survival Program targeting improvement in immunization coverage of children, prenatal care coverage for pregnant women, and contraceptive prevalence. Upon successful completion of performance benchmarks at the end of each year, USAID released monies to fund child survival activities for the following year. This program accomplished a major program goal, which was decentralization of health planning. The Philippine Department of Health soon incorporated provincial health planning. The Philippine Department of Health soon incorporated provincial health planning in its determination of allocation of resources. Social marketing activities contributed greatly to success in achieving the goal of boosting the immunization coverage rate for the 6 antigens listed under the Expanded Program for Immunization (51%-85% of infants, 1986-1991). In fact, rural health officers in Tarlac Province in Central Luzon went from household to household to talk to mothers about the benefits of immunizing a 1-year-old child, thereby contributing greatly to their achieving a 95% full immunization coverage rate by December 1991. Social marketing techniques included modern marketing strategies and multimedia channels. They first proved successful in metro Manila which, at the beginning of the campaign, had the lowest immunization rate of all 14 regions. Every Wednesday was designated immunization day and was when rural health centers vaccinated the children. Social marketing also successfully publicized oral rehydration therapy (ORT), breast feeding, and tuberculosis control. Another contributing factor to program success in child survival activities was private sector involvement. For example, the Philippine Pediatric Society helped to promote ORT as the preferred treatment for acute diarrhea. Further, the commercial sector distributed packets of oral rehydration salts and even advertised its own ORT product. At the end of 2

    Vlahos, L.; Machado, M. E.; Ramaty, R.; Murphy, R. J.; Alissandrakis, C.; Bai, T.; Batchelor, D.; Benz, A. O.; Chupp, E.; Ellison, D.


    Data is compiled from Solar Maximum Mission and Hinothori satellites, particle detectors in several satellites, ground based instruments, and balloon flights in order to answer fundamental questions relating to: (1) the requirements for the coronal magnetic field structure in the vicinity of the energization source; (2) the height (above the photosphere) of the energization source; (3) the time of energization; (4) transistion between coronal heating and flares; (5) evidence for purely thermal, purely nonthermal and hybrid type flares; (6) the time characteristics of the energization source; (7) whether every flare accelerates protons; (8) the location of the interaction site of the ions and relativistic electrons; (9) the energy spectra for ions and relativistic electrons; (10) the relationship between particles at the Sun and interplanetary space; (11) evidence for more than one acceleration mechanism; (12) whether there is single mechanism that will accelerate particles to all energies and also heat the plasma; and (13) how fast the existing mechanisms accelerate electrons up to several MeV and ions to 1 GeV.

  1. Accelerator design

    The feasibility of constructing a TeV region electron-positron linear collider in Japan is discussed. The design target of the collider is given as follows: Energy, 1 TeV + 1 TeV; luminosity, 1032-1033/cm2/s; total length, 25km; electric power, 250MW; energy dispersion, 1%-10%; the start of the first experiment, early 1990s. For realizing the above target, the following research and developmental works are necessary. (a) Development of an acceleration tube with short filling time and high shunt resistance. (b) Short pulse microwave source with high peak power. (c) High current, single bunch linac. (d) Beam dynamics. As for the acceleration tube, some possibility is considered: For example, the use of DAW (Disk and Washer) which is being developed for TRISTAN as a traveling-wave tube; and the Jungle Gym-type acceleration tube. As a promising candidate for the microwave source, the Lasertron has been studied. The total cost of the collider construction is estimated to be about 310 billion yen, of which 120 billion yen is for the tunnel and buildings, and 190 billion yen for the accelerator facilities. The operation cost is estimated to be about 3 billion yen per month. (Aoki, K.)

  2. Accelerator operations

    This section is concerned with the operation of both the tandem-linac system and the Dynamitron, two accelerators that are used for entirely different research. Developmental activities associated with the tandem and the Dynamitron are also treated here, but developmental activities associated with the superconducting linac are covered separately because this work is a program of technology development in its own right

  3. AIDS by mother-to-child transmission: survival analysis of cases followed from 1983 to 2002 in different regions of Brazil AIDS por transmissão vertical: análise de sobrevivência dos casos acompanhados entre 1983 e 2002 nas diferentes regiões do Brasil

    Luiza Harunari Matida


    Full Text Available Antiretroviral therapy contributes to decreasing morbidity and mortality, and ultimately to increasing survival. In Brazil, there are regional differences in HIV epidemiology regarding pregnant women and children with HIV/AIDS. This study evaluates survival time after AIDS diagnosis in 914 children infected by mother-to-child transmission, reported between 1983 and 1998 and followed until 2002, in Brazil's five regions. Time between birth and HIV diagnosis decreased over the years, mainly in the South and Southeast Regions. There was a significant improvement in survival; more than 75% of cases were still living four years after diagnosis in the 1997-1998 group. This Brazilian study demonstrates that even with regional inequalities in health care infrastructure it is possible for a developing country to establish an effective system of universal and free access to antiretroviral therapy that produces a significant increase in survival for children with AIDS.A terapia anti-retroviral contribui para a diminuição da morbidade e da mortalidade, com conseqüente aumento da sobrevida. No Brasil, há diferenças regionais relativas à dinâmica da epidemia do HIV e ao seu enfrentamento no grupo das gestantes e das crianças com HIV/AIDS. Este estudo verifica o tempo de sobrevida após o diagnóstico de AIDS em 914 crianças infectadas por transmissão vertical, entre os anos de 1983 e 1998, e acompanhadas até 2002, nas cinco regiões brasileiras. O tempo do nascimento ao diagnóstico de infecção pelo HIV, ao longo dos anos, apresenta uma diminuição, principalmente nos estados das regiões Sul e Sudeste. Houve melhora significativa da sobrevivência, mais de 75% dos casos ainda estavam vivendo quatro anos após o diagnóstico, no grupo de 1997 e 1998. Esta análise brasileira mostra ser possível para um país em desenvolvimento estabelecer um sistema efetivo de acesso gratuito e universal à terapia anti-retroviral, mesmo com dificuldades

  4. Advanced accelerators

    This report discusses the suitability of four novel particle acceleration technologies for multi-TeV particle physics machines: laser driven linear accelerators (linac), plasma beat-wave devices, plasma wakefield devices, and switched power and cavity wakefield linacs. The report begins with the derivation of beam parameters practical for multi-TeV devices. Electromagnetic field breakdown of materials is reviewed. The two-beam accelerator scheme for using a free electron laser as the driver is discussed. The options recommended and the conclusions reached reflect the importance of cost. We recommend that more effort be invested in achieving a self-consistent range of TeV accelerator design parameters. Beat-wave devices have promise for 1-100 GeV applications and, while not directly scalable to TeV designs, the current generation of ideas are encouraging for the TeV regime. In particular, surfatrons, finite-angle optical mixing devices, plasma grating accelerator, and the Raman forward cascade schemes all deserve more complete analysis. The exploitation of standard linac geometry operated in an unconventional mode is in a phase of rapid evolution. While conceptual projects abound, there are no complete designs. We recommend that a fraction of sponsored research be devoted to this approach. Wakefield devices offer a great deal of potential; trades among their benefits and constraints are derived and discussed herein. The study of field limitation processes has received inadequate attention; this limits experiment designers. The costs of future experiments are such that investment in understanding these processes is prudent. 34 refs., 12 figs., 3 tabs

  12. Accelerating networks

    Evolving out-of-equilibrium networks have been under intense scrutiny recently. In many real-world settings the number of links added per new node is not constant but depends on the time at which the node is introduced in the system. This simple idea gives rise to the concept of accelerating networks, for which we review an existing definition and-after finding it somewhat constrictive-offer a new definition. The new definition provided here views network acceleration as a time dependent property of a given system as opposed to being a property of the specific algorithm applied to grow the network. The definition also covers both unweighted and weighted networks. As time-stamped network data becomes increasingly available, the proposed measures may be easily applied to such empirical datasets. As a simple case study we apply the concepts to study the evolution of three different instances of Wikipedia, namely, those in English, German, and Japanese, and find that the networks undergo different acceleration regimes in their evolution

    Holger Strulik


    The paper presents a model where the interplay between fertility, child labour, and education can explain economic stagnation when parents live in an environment of high child mortality. If in contrast child mortality is low, the solution of the parental decision problem leads to perpetual economic growth. The two long-run states are connected by a path of demographic transition and economic take-off along which the incidence of child labour disappears. The paper also discusses alternative po...

  14. Child Care Subsidies and Child Development

    Herbst, Chris M.; Tekin, Erdal


    Child care subsidies are an important part of federal and state efforts to move welfare recipients into employment. One of the criticisms of the current subsidy system, however, is that it overemphasizes work and does little to encourage parents to purchase high-quality child care. Consequently, there are reasons to be concerned about the implications of child care subsidies for child development. In this paper, we provide a systematic assessment of the impact of subsidy receipt on a wide ran...

  16. On hunger and child mortality in India.

    Gaiha, Raghav; Kulkarni, Vani S; Pandey, Manoj K; Imai, Katsushi S


    Despite accelerated growth there is pervasive hunger, child undernutrition and mortality in India. Our analysis focuses on their determinants. Raising living standards alone will not reduce hunger and undernutrition. Reduction of rural/urban disparities, income inequality, consumer price stabilization, and mothers’ literacy all have roles of varying importance in different nutrition indicators. Somewhat surprisingly, public distribution system (PDS) do not have a significant effect on any of them. Generally, child undernutrition and mortality rise with poverty. Our analysis confirms that media exposure triggers public action, and helps avert child undernutrition and mortality. Drastic reduction of economic inequality is in fact key to averting child mortality, conditional upon a drastic reordering of social and economic arrangements. PMID:22451985

    In this paper, standing back--looking from afar--and adopting a historical perspective, the field of accelerator science is examined. How it grew, what are the forces that made it what it is, where it is now, and what it is likely to be in the future are the subjects explored. Clearly, a great deal of personal opinion is invoked in this process.

    Gerald Cradock


    Expectations of contemporary child protection apparatuses are strongly influenced by beliefs inherited from the nineteenth century child rescue movement. In particular, the belief that child abuse determination is obvious.

Moreover, the proliferation of kinds of child abuse, and the need to distinguis...

  3. Accelerator system and method of accelerating particles

    Wirz, Richard E. (Inventor)


    An accelerator system and method that utilize dust as the primary mass flux for generating thrust are provided. The accelerator system can include an accelerator capable of operating in a self-neutralizing mode and having a discharge chamber and at least one ionizer capable of charging dust particles. The system can also include a dust particle feeder that is capable of introducing the dust particles into the accelerator. By applying a pulsed positive and negative charge voltage to the accelerator, the charged dust particles can be accelerated thereby generating thrust and neutralizing the accelerator system.

  4. The child sexual abuse accommodation syndrome.

    Summit, R C


    Child victims of sexual abuse face secondary trauma in the crisis of discovery. Their attempts to reconcile their private experiences with the realities of the outer world are assaulted by the disbelief, blame and rejection they experience from adults. The normal coping behavior of the child contradicts the entrenched beliefs and expectations typically held by adults, stigmatizing the child with charges of lying, manipulating or imagining from parents, courts and clinicians. Such abandonment by the very adults most crucial to the child's protection and recovery drives the child deeper into self-blame, self-hate, alienation and revictimization. In contrast, the advocacy of an empathic clinician within a supportive treatment network can provide vital credibility and endorsement for the child. Evaluation of the responses of normal children to sexual assault provides clear evidence that societal definitions of "normal" victim behavior are inappropriate and procrustean, serving adults as mythic insulators against the child's pain. Within this climate of prejudice, the sequential survival options available to the victim further alienate the child from any hope of outside credibility or acceptance. Ironically, the child's inevitable choice of the "wrong" options reinforces and perpetuates the prejudicial myths. The most typical reactions of children are classified in this paper as the child sexual abuse accommodation syndrome. The syndrome is composed of five categories, of which two define basic childhood vulnerability and three are sequentially contingent on sexual assault: (1) secrecy, (2) helplessness, (3) entrapment and accommodation, (4) delayed, unconvincing disclosure, and (5) retraction. The accommodation syndrome is proposed as a simple and logical model for use by clinicians to improve understanding and acceptance of the child's position in the complex and controversial dynamics of sexual victimization. Application of the syndrome tends to challenge entrenched

  6. Is genetic background important in lung cancer survival?

    Linda S Lindström

    Full Text Available BACKGROUND: In lung cancer, a patient's survival is poor with a wide variation in survival within the stage of disease. The aim of this study was to investigate the familial concordance in lung cancer survival by means of analyses of pairs with different degrees of familial relationships. METHODS: Our population-based Swedish family database included three million families and over 58,100 lung cancer patients. We modelled the proband (parent, sibling, spouse survival utilizing a multivariate proportional hazard (Cox model adjusting for possible confounders of survival. Subsequently, the survival in proband's relative (child, sibling, spouse was analysed with a Cox model. FINDINGS: By use of Cox modelling with 5 years follow-up, we noted a decreased hazard ratio for death in children with good parental survival (Hazard Ratio [HR] = 0.71, 95% CI = 0.51 to 0.99, compared to those with poor parental survival. Also for siblings, a very strong protective effect was seen (HR = 0.14, 95% CI = 0.030 to 0.65. Finally, in spouses no correlation in survival was found. INTERPRETATION: Our findings suggest that genetic factors are important in lung cancer survival. In a clinical setting, information on prognosis in a relative may be vital in foreseeing the survival in an individual newly diagnosed with lung cancer. Future molecular studies enhancing the understanding of the underlying mechanisms and pathways are needed.

    An infant was born with an unusual combination of primitive foregut anomalies consisting of complete proximal tracheal atresia, proximal esophageal atresia and distal tracheoesophageal fistula. Before the birth, the family physician suspected an anomaly of the upper airway or esophageal occlusion on the basis of hydramnios evident at the thirty-third to thirty-fourth week of gestation, and earlier amniocentesis which indicated a normal level of α-fetoprotein. He consulted the hospital obstetr...

  13. Multinationals and plant survival

    Bandick, Roger


    The aim of this paper is twofold: first, to investigate how different ownership structures affect plant survival, and second, to analyze how the presence of foreign multinational enterprises (MNEs) affects domestic plants’ survival. Using a unique and detailed data set on the Swedish manufacturing...... sector, I am able to separate plants into those owned by foreign MNEs, domestic MNEs, exporting non-MNEs, and purely domestic firms. In line with previous findings, the result, when conditioned on other factors affecting survival, shows that foreign MNE plants have lower survival rates than non......-MNE plants. However, separating the non-MNEs into exporters and non-exporters, the result shows that foreign MNE plants have higher survival rates than non-exporting non-MNEs, while the survival rates of foreign MNE plants and exporting non-MNE plants do not seem to differ. Moreover, the simple non...

  14. Survival Data and Regression Models

    Grégoire, G.


    We start this chapter by introducing some basic elements for the analysis of censored survival data. Then we focus on right censored data and develop two types of regression models. The first one concerns the so-called accelerated failure time models (AFT), which are parametric models where a function of a parameter depends linearly on the covariables. The second one is a semiparametric model, where the covariables enter in a multiplicative form in the expression of the hazard rate function. The main statistical tool for analysing these regression models is the maximum likelihood methodology and, in spite we recall some essential results about the ML theory, we refer to the chapter "Logistic Regression" for a more detailed presentation.

  15. Deep Survival Analysis

    Ranganath, Rajesh; Perotte, Adler; Elhadad, Noémie; Blei, David


    The electronic health record (EHR) provides an unprecedented opportunity to build actionable tools to support physicians at the point of care. In this paper, we investigate survival analysis in the context of EHR data. We introduce deep survival analysis, a hierarchical generative approach to survival analysis. It departs from previous approaches in two primary ways: (1) all observations, including covariates, are modeled jointly conditioned on a rich latent structure; and (2) the observation...

  16. Transformation survival models

    Yulia Marchenko


    The Cox proportional hazards model is one of the most popular methods for analyzing survival or failure-time data. The key assumption underlying the Cox model is that of proportional hazards. This assumption may often be violated in practice. Transformation survival models extend the Cox regression methodology to allow for nonproportional hazards. They represent the class of semiparametric linear transformation models, which relates an unknown transformation of the survival time linearly to c...

  1. Who Owns Child Abuse?

    Gerald Cradock


    Full Text Available Expectations of contemporary child protection apparatuses are strongly influenced by beliefs inherited from the nineteenth century child rescue movement. In particular, the belief that child abuse determination is obvious. However, this assumption fails to make a distinction between nineteenth century’s emphasis on impoverished environments and the twentieth century introduction of the pathological child abuser. Moreover, the proliferation of kinds of child abuse, and the need to distinguish child abusers from non-abusers, means knowledge is now spread across an array of disciplines and professions, which necessarily destabilizes the definition of child abuse. The increasing exposure of alternate care systems as potentially abusive has similarly destabilized the old common sense solution to neglected children—namely removal. Finally, as uncertainty increases, and definitions become more divergent, the question of what child abuse is, and what should be done about it, becomes increasingly politicized.

    Herbst, Chris M.; Tekin, Erdal


    Child care subsidies are an important part of federal and state efforts to move welfare recipients into employment. One of the criticisms of the current subsidy system, however, is that it overemphasizes work and does little to encourage parents to purchase high-quality child care. Consequently, there are reasons to be concerned about the…

At meso level it explores the effect of labour market conditions on child labour. As the above two levels of analysis are mainly concerned with the demand for child labour, the micro level analysis expl...

  6. Child Poverty in Canada

    Thomas Crossley; Lori Curtis


    A 1989 all-party motion of parliament called for the elimination of child poverty in Canada by the year 2000. Despite a series of policy initiatives, recent reports suggest that the child poverty rate may now be comparable to that in 1989. The apparent persistence of child poverty in Canada might reflect socioeconomic developments, or something about the way that child poverty is measured. Using micro data covering the period 1986 to 2000 we find little support for these explanations.

  9. Maternal education and child mortality in Zimbabwe.

    Grépin, Karen A; Bharadwaj, Prashant


    In 1980, Zimbabwe rapidly expanded access to secondary schools, providing a natural experiment to estimate the impact of increased maternal secondary education on child mortality. Exploiting age specific exposure to these reforms, we find that children born to mothers most likely to have benefited from the policies were about 21% less likely to die than children born to slightly older mothers. We also find that increased education leads to delayed age at marriage, sexual debut, and first birth and that increased education leads to better economic opportunities for women. We find little evidence supporting other channels through which increased education might affect child mortality. Expanding access to secondary schools may greatly accelerate declines in child mortality in the developing world today. PMID:26569469

    A survival model is derived from the exponential function using the concept of fractional differentiation. The hazard function of the proposed model generates various shapes of curves including increasing, increasing-constant-increasing, increasing-decreasing-increasing, and so-called bathtub hazard curve. The model also contains a parameter that is the maximum of the survival time.

  16. Hepatitis B and alcohol affect survival of hepatocellular carcinoma patients

    Linda L. Wong; Whitney M. Limm; Naoky Tsai; Richard Severino


    AIM: In the USA, Hawaii has the highest incidence of hepatocellular carcinoma (HCC) and a diverse population.It is an ideal place to characterize HCC in the context of ethnicity/risk factors.METHODS: A total of 262 cases of HCC (1992-2003) were retrospectively reviewed for demographics, ethnicity, birthplace, viral hepatitis, alcohol use, diabetes, smoking and risk factors for viral hepatitis such as intravenous drug abuse (IVDA), transfusions, tattoos and vertical transmission. Tumor stage, Child's class, Cancer of the Liver Italian Program (CLIP) score, α-fetoprotein level, treatment and survival were recorded.RESULTS: Gender, age, viral hepatitis, alcohol, IVDA, and diabetes differed significantly in Asians, non-Asians and Pacific Islanders. There were also specific differences within Asian subgroups. Alpha-fetoprotein, smoking, transfusions, stage and resectability did not differ between groups. Asians were more likely to have hepatitis B, while non-Asians were more likely to have hepatitis C. Factors that decreased survival included hepatitis B, alcohol, elevated alpha-fetoprotein, CLIP >2 and increased Child's class. When Asians were combined with Pacific Islanders, median survival (1.52 years vs 3.54 years), 1- and 3-year survival was significantly worse than those for non-Asians. After Cox regression analysis for hepatitis B and alcohol, there was no difference in survival by ethnicity.CONCLUSION: Various ethnicities have different risk factors for HCC. Hepatitis B, alcohol, and α-fetoprotein are more important factors for survival than ethnicity.

  17. Acceleration without Horizons

    Doria, Alaric; Munoz, Gerardo


    We derive the metric of an accelerating observer moving with non-constant proper acceleration in flat spacetime. With the exception of a limiting case representing a Rindler observer, there are no horizons. In our solution, observers can accelerate to any desired terminal speed $v_{\\infty} < c$. The motion of the accelerating observer is completely determined by the distance of closest approach and terminal velocity or, equivalently, by an acceleration parameter and terminal velocity.

  18. Survival of falling robots

    Cameron, Jonathan M.; Arkin, Ronald C.


    As mobile robots are used in more uncertain and dangerous environments, it will become important to design them so that they can survive falls. In this paper, we examine a number of mechanisms and strategies that animals use to withstand these potentially catastrophic events and extend them to the design of robots. A brief survey of several aspects of how common cats survive falls provides an understanding of the issues involved in preventing traumatic injury during a falling event. After outlining situations in which robots might fall, a number of factors affecting their survival are described. From this background, several robot design guidelines are derived. These include recommendations for the physical structure of the robot as well as requirements for the robot control architecture. A control architecture is proposed based on reactive control techniques and action-oriented perception that is geared to support this form of survival behavior.

    Abstract A new two-parameter probability distribution called hypertabastic is introduced to model the survival or time-to-event data. A simulation study was carried out to evaluate the performance of the hypertabastic distribution in comparison with popular distributions. We then demonstrate the application of the hypertabastic survival model by applying it to data from two motivating studies. The first one demonstrates the proportional hazards version of the model by applying it to a data se...

  2. Phenomenological Theory of Survival

    Azbel', Mark Ya.


    Theoretical analysis proves that human survivability is dominated by an unusual physical, rather than biological, mechanism, which yields an exact law. The law agrees with all experimental data, but, contrary to existing theories, it is the same for an entire species, i.e., it is independent of the population, its phenotypes, environment and history. The law implies that the survivability changes with environment via phase transitions, which are simultaneous for all generations. They allow fo...

    Minh Cong Nguyen; Quentin Wodon


    Child or early marriage is recognized as an important development and human rights issue that affects girls especially in many developing countries. The practice has been linked to psychological, health, and education risks. These negative impacts explain why in many countries child marriage has been prohibited by law but often with little effect. While child marriage has been recognized as a major issue, its measurement has remained unsophisticated. Existing studies tend to simply report the...

  11. Is Child Labor Inefficient?

    Jean-Marie Baland; Robinson, James A.


    We build a model of child labor and study its implications for welfare. We assume that there is a trade-off between child labor and the accumulation of human capital. Even if parents are altruistic and child labor is socially inefficient, it may arise in equilibrium because parents fail to fully internalize its negative effects. This occurs when bequests are zero or when capital markets are imperfect. We also study the effects of a simple ban on child labor and derive conditions under which i...

  12. Fermionic entanglement that survives a black hole

    We introduce an arbitrary number of accessible modes when analyzing bipartite entanglement degradation due to Unruh effect between two partners Alice and Rob. Under the single mode approximation (SMA) a fermion field only had a few accessible levels due to Pauli exclusion principle conversely to bosonic fields which had an infinite number of excitable levels. This was argued to justify entanglement survival in the fermionic case in the SMA infinite acceleration limit. Here we relax SMA. Hence, an infinite number of modes are excited as the observer Rob accelerates, even for a fermion field. We will prove that, despite this analogy with the bosonic case, entanglement loss is limited. We will show that this comes from fermionic statistics through the characteristic structure it imposes on the infinite dimensional density matrix for Rob. Surprisingly, the surviving entanglement is independent of the specific maximally entangled state chosen, the kind of fermionic field analyzed, and the number of accessible modes considered. We shall discuss whether this surviving entanglement goes beyond the purely statistical correlations, giving insight concerning the black hole information paradox.

  17. The direction of acceleration

    Wilhelm, Thomas; Burde, Jan-Philipp; Lück, Stephan


    Acceleration is a physical quantity that is difficult to understand and hence its complexity is often erroneously simplified. Many students think of acceleration as equivalent to velocity, a ˜ v. For others, acceleration is a scalar quantity, which describes the change in speed Δ|v| or Δ|v|/Δt (as opposed to the change in velocity). The main difficulty with the concept of acceleration therefore lies in developing a correct understanding of its direction. The free iOS app AccelVisu supports students in acquiring a correct conception of acceleration by showing acceleration arrows directly at moving objects.

Every infant and child has the right to good nutrition acc...

  20. Social determinants of child mortality in Niger: Results from the 2012 National Verbal and Social Autopsy Study

    Koffi, Alain K; Maina, Abdou; Yaroh, Asma Gali; Habi, Oumarou; Bensaïd, Khaled; Kalter, Henry D


    Background Understanding the determinants of preventable deaths of children under the age of five is important for accelerated annual declines – even as countries achieve the UN’s Millennium Development Goals and the target date of 2015 has been reached. While research has documented the extent and nature of the overall rapid decline in child mortality in Niger, there is less clear evidence to provide insight into the contributors to such deaths. This issue is the central focus of this paper. Methods We analyzed a nationally representative cross–sectional sample of 620 child deaths from the 2012 Niger Verbal Autopsy/Social Autopsy (VASA) Survey. We conducted a descriptive analysis of the data on preventive and curative care, guided by the coverage of proven indicators along the continuum of well child care and illness recognition and care–seeking for child illnesses encompassed by the BASICS/CDC Pathway to Survival model. Results Six hundred twenty deaths of children (1–59 months of age) were confirmed from the VASA survey. The majority of these children lived in households with precarious socio–economic conditions. Among the 414 children whose fatal illnesses began at age 0–23 months, just 24.4% were appropriately fed. About 24% of children aged 12–59 months were fully immunized. Of 601 children tracked through the Pathway to Survival, 62.4% could reach the first health care provider after about 67 minutes travel time. Of the 306 children who left the first health care provider alive, 161 (52.6%) were not referred for further care nor received any home care recommendations, and just 19% were referred to a second provider. About 113 of the caregivers reported cost (35%), distance (35%) and lack of transport (30%) as constraints to care–seeking at a health facility. Conclusion Despite Niger’s recent major achievements in reducing child mortality, the following determinants are crucial to continue building on the gains the country has made

  18. Standing wave linear accelerator

    Consideration is being given to standing wave linear accelerator containing generator, phase shifter, two accelerating resonator sections, charged particle injector and waveguide bridge. Its first arm is oined up with generator via the phase shifter, the second and the third ones-with accelerating sections and the fourth one - with HF-power absorber. HF-power absorber represents a section of circular diaphragmatic wavequide with transformer with input wave and intrawaveguide output load located between injector and the first accelerating section. The section possesses holes in side walls lying on accelerator axis. The distances between centers of the last cell of the fast accelerating section and the first cell of the second accelerating sectiOn equal (2n+3)lambda/4, where n=1, 2, 3..., lambda - wave length of generator. The suggested system enables to improve by one order spectral characteristics of accelerators as compared to the prototype in which magnetrons are used as generator

  1. Survival after judicial hanging.

    Sabermoghaddam, Mohsen; Abad, Mohsen; Golmakani, Ebrahim; Mozaffari, Nasrollah


    Hanging is known not only as a common method of suicide but also as a capital punishment method in some countries. Although several cases have been reported to survive after the attempted suicidal/accidental hanging, to the extent of our knowledge, no modern case of survival after judicial hanging exists. We reported a case of an individual who revived after modern judicial hanging despite being declared dead. The case was admitted with poor clinical presentations and the Glasgow Coma Scale of 6/15. The victim received all the standard supportive intensive care and gained complete clinical recovery. PMID:25747958

  4. Maximal Acceleration Is Nonrotating

    Page, Don N.


    In a stationary axisymmetric spacetime, the angular velocity of a stationary observer that Fermi-Walker transports its acceleration vector is also the angular velocity that locally extremizes the magnitude of the acceleration of such an observer, and conversely if the spacetime is also symmetric under reversing both t and phi together. Thus a congruence of Nonrotating Acceleration Worldlines (NAW) is equivalent to a Stationary Congruence Accelerating Locally Extremely (SCALE). These congruenc...

  5. Accelerators at school

    Latest subject covered by the CERN Accelerator School was 'Applied Geodesy of Particle Accelerators', which attracted an impressive number of outside participants to CERN for a week in April. Since the forerunners of today's particle accelerators were demonstrated over 50 years ago, the positioning of accelerator components has progressed from the laboratory bench-top to tunnels tens of kilometres long. Despite this phenomenal growth in size, sub-millimetre accuracy is still required

  6. A Solid state accelerator

    We present a solid state accelerator concept utilizing particle acceleration along crystal channels by longitudinal electron plasma waves in a metal. Acceleration gradients of order 100 GV/cm are theoretically possible, but channeling radiation limits the maximum attainable energy to 105 TeV for protons. Beam dechanneling due to multiple scattering is substantially reduced by the high acceleration gradient. Plasma wave dissipation and generation in metals are also discussed

  9. Accelerator development in BARC

    Charged particle accelerators have played crucial role in the field of both basic and applied sciences. This has been possible because the accelerators have been extensively utilized from unraveling the secrets of nature to diverse applications such as implantation, material modification, medical diagnostics and therapy, nuclear energy and clean air and water. The development of accelerators in BARC can be categorized in two broad categories namely proton and heavy ion based accelerators and electron based accelerators. The heavy ion accelerators with sufficiently high energies are currently being used for conducting frontline nuclear and allied research whereas the electron accelerators are being routinely used for various industrial applications. Recently, there is a strong interest for developing the high energy and high intensity accelerators due to their possibility of effective utilization towards concept of energy amplification (Accelerator Driven System), incineration nuclear waste and transmutation. This talk will discuss details of the accelerator development program in BARC with particular emphasis on the recent development at Low Energy High Intensity Proton Accelerator (LEHIPA) Facility in Ion Accelerator Development Division, BARC.

  19. Impacts of Climate Change on Inequities in Child Health.

    Bennett, Charmian M; Friel, Sharon


    This paper addresses an often overlooked aspect of climate change impacts on child health: the amplification of existing child health inequities by climate change. Although the effects of climate change on child health will likely be negative, the distribution of these impacts across populations will be uneven. The burden of climate change-related ill-health will fall heavily on the world's poorest and socially-disadvantaged children, who already have poor survival rates and low life expectancies due to issues including poverty, endemic disease, undernutrition, inadequate living conditions and socio-economic disadvantage. Climate change will exacerbate these existing inequities to disproportionately affect disadvantaged children. We discuss heat stress, extreme weather events, vector-borne diseases and undernutrition as exemplars of the complex interactions between climate change and inequities in child health. PMID:27417491

  1. The Accelerator Reliability Forum

    Lüdeke, Andreas; Giachino, R


    A high reliability is a very important goal for most particle accelerators. The biennial Accelerator Reliability Workshop covers topics related to the design and operation of particle accelerators with a high reliability. In order to optimize the over-all reliability of an accelerator one needs to gather information on the reliability of many different subsystems. While a biennial workshop can serve as a platform for the exchange of such information, the authors aimed to provide a further channel to allow for a more timely communication: the Particle Accelerator Reliability Forum [1]. This contribution will describe the forum and advertise it’s usage in the community.

    In this dissertation, the direct laser acceleration (DLA) of ionization-injected electrons in a laser wakefield accelerator (LWFA) operating in the quasi-blowout regime has been investigated through experiment and simulation. In the blowout regime of LWFA, the radiation pressure of an intense laser pulse can push a majority of the plasma electrons out and around the main body of the pulse. The expelled plasma electrons feel the electrostatic field of the relatively-stationary ions and are t...

  3. Child Odors and Parenting: A Survey Examination of the Role of Odor in Child-Rearing

    Okamoto, Masako; Shirasu, Mika; Fujita, Rei; Hirasawa, Yukei; Touhara, Kazushige


    Parental caregiving is critical for the survival of our young and continuation of our species. In humans, visual and auditory signals from offspring have been shown to be potent facilitators of parenting. However, whether odors emitted by our young also influence human parenting remains unclear. To explore this, we conducted a series of questionnaire surveys targeting parents with children under 6 years old. First, we collected episodes on experiencing odors/sniffing various parts of a child’s body (n = 507). The prevalence of experiencing events described in those episodes was examined in a separate survey (n = 384). Based on those results, the Child Odor in Parenting scale (COPs) was developed, and subsequently used in the main survey (n = 888). We found COPs to have adequate content validity, concurrent validity, and reliability. Responses to the COPs demonstrated that parents, especially mothers with infants, are aware of odors from their offspring, and actively seek them in daily child-rearing. The factor structure and content of the COPs items indicated that child odors have both affective and instrumental roles. Affective experiences induce loving feeling and affectionate sniffing, while instrumental experiences pertain to specific hygienic needs. The head was the most frequent source of affective experiences, and the child’s bottom of instrumental. Each was experienced by more than 90% of the mothers with a child below 1 year of age. Affective experiences significantly declined as the child grew older, possibly associated with the decline of physical proximity between parents and child. This age-related decline was not prominent for instrumental experiences, except for the bottom, which significantly declined after 3 years of age. The present findings suggest that child odors play roles in human parenting, and that their nature and significance change during the course of a child’s development. PMID:27138751

  4. Child Abuse in India

    Mohammad Reza Iravani


    Full Text Available Child abuse is harm to, or neglect of, a child by another person, whether adult or child. Child abuse happens in all cultural, ethnic, and income groups. Child abuse can be physical, emotional - verbal, sexual or through neglect. Abuse may cause serious injury to the child and may even result in death. A problem that is only beginning to come into light in India rape, sexual abuse, and sexual harassment are worldwide issues of gender violence. There is very little research done in this area in India and only a few books have been written, keeping the subject even further from the consciousness of the country. However, the problem persists with staggering incidence, and Indians unique profile adds to the complexity of an already difficult subject. Fortunately, the issue of child sexual abuse is slowly becoming a more recognized issue, and for this reason, this paper will focus much on sexual abuse against minor children: the laws, victims, and perpetrators. Finally, an analysis of the aspects of Indian culture that make this issue particularly difficult to understand and cope with will be presented.

  5. Child maltreatment in India.

    Singhi, Pratibha; Saini, Arushi Gahlot; Malhi, Prabhjot


    Child maltreatment is a global problem but is more difficult to assess and manage in developing countries such as India where one-fifth of the world's total child population resides. Certain forms of maltreatment such as feticide, infanticide, abandonment, child labour, street-begging, corporal punishment and battered babies are particularly prevalent in India. Most physicians still need to be sensitized in order to suspect child abuse on the basis of unexplained trauma, multiple fractures, parental conflict and other corroborative evidence. This article summarizes the various aspects of this major problem in resource-poor settings in the hope that it will assist in the planning of services addressing child physical and sexual abuse and neglect in India and in other developing countries. A culture of non-violence towards children needs to be built into communities in order to provide an environment conducive to the overall development of the child. Rehabilitation of abused children and their families requires a multi-disciplinary service including paediatricians, child psychologists and social workers, and the training of police forces in how to tackle the problem.

  6. Muon Acceleration Concepts for Future Neutrino Factory

    Bogacz, Slawomir Alex [Thomas Jefferson National Accelerator Facility (TJNAF), Newport News, VA (United States)


    Here, we summarize current state of concept for muon acceleration aimed at future Neutrino Factory. The main thrust of these studies was to reduce the overall cost while maintaining performance through exploring interplay between complexity of the cooling systems and the acceptance of the accelerator complex. To ensure adequate survival of the short-lived muons, acceleration must occur at high average gradient. The need for large transverse and longitudinal acceptances drives the design of the acceleration system to initially low RF frequency, e.g. 325 MHz, and then increased to 650 MHz, as the transverse size shrinks with increasing energy. High-gradient normal conducting RF cavities at these frequencies require extremely high peak-power RF sources. Hence superconducting RF (SRF) cavities are chosen. Here, we considered two cost effective schemes for accelerating muon beams for a stagable Neutrino Factory: Exploration of the so-called 'dual-use' linac concept, where the same linac structure is used for acceleration of both H- and muons and alternatively, the SRF efficient design based on multi-pass (4.5) 'dogbone' RLA, extendable to multi-pass FFAG-like arcs.

    Norman, Rosana E.; Byambaa, Munkhtsetseg; De, Rumna; Butchart, Alexander; Scott, James; Vos, Theo


    Editors' Summary Background Child maltreatment—the abuse and neglect of children—is a global problem. There are four types of child maltreatment—sexual abuse (the involvement of a child in sexual activity that he or she does not understand, is unable to give consent to, or is not developmentally prepared for), physical abuse (the use of physical force that harms the child's health, survival, development, or dignity), emotional abuse (the failure to provide a supportive environment by, for exa...

  9. Nutrition and maternal, neonatal, and child health.

    Christian, Parul; Mullany, Luke C; Hurley, Kristen M; Katz, Joanne; Black, Robert E


    This article reviews the central role of nutrition in advancing the maternal, newborn, and child health agenda with a focus on evidence for effective interventions generated using randomized controlled trials in low- and middle-income countries (LMIC). The 1000 days spanning from conception to 2 years of life are a critical period of time when nutritional needs must be ensured; failure to do so can lead to adverse impacts on short-term survival as well as long-term health and development [corrected]. The burden of maternal mortality continues to be high in many under-resourced settings; prenatal calcium supplementation in populations with low intakes can reduce the risk of pre-eclampsia and eclampsia morbidity and mortality and is recommended, and antenatal iron-folic acid use in many countries may reduce anemia, a condition that may be an underlying factor in postpartum hemorrhage. Sufficient evidence exists to promote multiple micronutrient supplementation during pregnancy to reduce fetal growth restriction and low birth weight. Early initiation of breastfeeding (within an hour), exclusive breastfeeding in the first 6 months of life, and vitamin A supplementation in the first few days of life in Asia (but not in Africa) reduce infant mortality. Biannual large-dose vitamin A supplements to children 6-59 months of age and zinc for treatment of diarrhea continue to be important strategies for improving child health and survival. Early nutrition and micronutrient status can influence child development but should be integrated with early responsive learning interventions. Future research is needed that goes beyond the 1000 days to ensure adequate preconceptional nutrition and health, with special emphasis on adolescents who contribute to a large proportion of first births in many LMIC. Thus, we make the case for integrating proven nutrition interventions with those for health in pregnant women, and with those for health and child development in neonates, infants, and

    Amelia Bastos; Graca Leao Fernandes,; Jose Passos


    This paper is a study on child poverty from two perspectives: child income poverty (derived from family income) and child deprivation (evaluated by non-monetary indicators). On the one hand, empirical evidence supports the thesis that income-based poverty measures and deprivation measures do not overlap. On the other hand, the relationship between poverty and the child's living conditions is not linear. Uses micro-econometric techniques to analyse child income poverty and present deprivation ...

  12. Social development and the girl child.

    Gangrade, K D


    This article discusses the social development of female children in India. Social development is "not merely an effort to provide ad hoc growth targets in each of the sectors of planning," but an integrative concept. Sustainable human development, according to Gus Speth (1994), is development that not only generates economic growth, it distributes its benefits equitably, regenerates the environment, and empowers people. India is ranked as 5th out of 132 countries in the 1994 World Bank Report, but 135th out of 173 in the Human Development Report. In India, there were 9000 dowry-related deaths in 1993. Son preference occurs regardless of social class. The sex ratio declined as low as 811 females per 1000 males in Jaisalmer district of Rajasthan. The government of India developed a National Action Plan that is committed to the survival, protection, and development of female children. The Integrated Child Development Scheme, in 2696 blocks with a coverage of 250,000 villages and 224 urban slum areas, has demonstrated its effectiveness in increased child nutrition. Survival of girl children is 50% less than male survival in the first 30 days of life. Under 50% of girls are enrolled in schools. Bihar state is particularly backward in enhancing girls' status through modernization and increased female enrollments. Child labor may contribute about 25-29% of gross national product. Bihar, Madhya Pradesh, Rajasthan, and Uttar Pradesh, with 40% of the total population, have over 60% of their females marrying below the age of 20 years. Recommended are universal enrollment of all children from scheduled caste and tribes; nonformal educational options for school drop outs, working children, and girls who cannot attend school; and increasing upper school education of girls. A variety of other recommendations are made on improving the status of women for working women, unmarried single women, and women in general. PMID:12158018

  14. Survival of the cheapest

    Julian F.V Vincent


    The natural world, of which we are a significant part, has many examples of survival with minimum use of energy. These examples range from the production and use of materials to the organization of entire populations. But not all organisms exist in a half-lit, miserly half-life. Their (that is to say, our driving purpose in life is to reproduce, and no organism (that is, me or you would be here unless our parents had a strong urge to reproduce, something which we, mostly, inherit. So any way that we can have the largest number of surviving offspring will be favored. In doing this we are in competition with nearly all the other organisms in the vicinity. The ones with which we are overtly friendly are our immediate genetic (or to a lesser extent, social relatives, and much has been made of the concept that it is our genes, rather than ourselves, that crave dominance.

  15. Particle-accelerator decommissioning

    Generic considerations involved in decommissioning particle accelerators are examined. There are presently several hundred accelerators operating in the United States that can produce material containing nonnegligible residual radioactivity. Residual radioactivity after final shutdown is generally short-lived induced activity and is localized in hot spots around the beam line. The decommissioning options addressed are mothballing, entombment, dismantlement with interim storage, and dismantlement with disposal. The recycle of components or entire accelerators following dismantlement is a definite possibility and has occurred in the past. Accelerator components can be recycled either immediately at accelerator shutdown or following a period of storage, depending on the nature of induced activation. Considerations of cost, radioactive waste, and radiological health are presented for four prototypic accelerators. Prototypes considered range from small accelerators having minimal amounts of radioactive mmaterial to a very large accelerator having massive components containing nonnegligible amounts of induced activation. Archival information on past decommissionings is presented, and recommendations concerning regulations and accelerator design that will aid in the decommissioning of an accelerator are given

  8. Adult headform impact tests of three Japanese child bicycle helmets into a vehicle.

    Mizuno, Koji; Ito, Daisuke; Yoshida, Ryoichi; Masuda, Hiroyuki; Okada, Hiroshi; Nomura, Mitsunori; Fujii, Chikayo


    The head is the body region that most frequently incurs fatal and serious injuries of cyclists in collisions against vehicles. Many research studies investigated helmet effectiveness in preventing head injuries using accident data. In this study, the impact attenuation characteristics of three Japanese child bicycle helmets were examined experimentally in impact tests into a concrete surface and a vehicle. A pedestrian adult headform with and without a Japanese child bicycle helmet was dropped onto a concrete surface and then propelled into a vehicle at 35 km/h in various locations such as the bonnet, roof header, windshield and A-pillar. Accelerations were measured and head injury criterion (HIC) calculated. In the drop tests using the adult headform onto a concrete surface from the height of 1.5m, the HIC for a headform without a child helmet was 6325, and was reduced by around 80% when a child helmet was fitted to the headform. In the impact tests, where the headform was fired into the vehicle at 35 km/h at various locations on a car, the computed acceleration based HIC varied depending on the vehicle impact locations. The HIC was reduced by 10-38% for impacts headforms with a child helmet when the impact was onto a bonnet-top and roof header although the HIC was already less than 1000 in impacts with the headform without a child helmet. Similarly, for impacts into the windshield (where a cyclist's head is most frequently impacted), the HIC using the adult headform without a child helmet was 122; whereas when the adult headform was used with a child helmet, a higher HIC value of more than 850 was recorded. But again, the HIC values are below 1000. In impacts into the A-pillar, the HIC was 4816 for a headform without a child helmet and was reduced by 18-38% for a headform with a child helmet depending on the type of Japanese child helmet used. The tests demonstrated that Japanese child helmets are effective in reducing accelerations and HIC in a drop test using

    Wild, N J; Wynne, J M


    Details of 11 child sex rings identified in one working class community were obtained by interviewing investigating police officers and examining health and social services records. The rings contained 14 adult male perpetrators and 175 children aged 6-15 years. Most perpetrators used child ringleaders to recruit victims; others became a "family friend" or obtained a position of authority over children. Secrecy was encouraged and bribery, threats, and peer pressure used to induce participatio...

  13. ''Battered child'' syndrome

    Synonyms for the 'battered child' syndrome (BCS) are terms describing the physical and body aspects of the process, such as 'child abuse', or 'non-accidental injury'. These are to be distinguished from the psychic aspects and abuse, emotional and bodily neglect, and sexual abuse. Most cases are one or another combination of these aspects. Radiology is the essential method for giving proof of such abuses, identifying the signs of maltreatment in a medical record, or for disproving suspected abuse. (orig./AJ)

    Purpose: The purpose of this study was to report on the 5-year survival of hepatocellular carcinoma (HCC) patients treated with DC Bead loaded with doxorubicin (DEB-DOX) in a scheduled scheme in up to three treatments and thereafter on demand. Materials and Methods: 173 HCC patients not suitable for curable treatments were prospectively enrolled (mean age 70.4 {+-} 7.4 years). Child-Pugh (Child) class was A/B (102/71 [59/41 %]), Okuda stage was 0/1/2 (91/61/19 [53.2/35.7/11.1 %]), and mean lesion diameter was 7.6 {+-} 2.1 cm. Lesion morphology was one dominant {<=}5 cm (22 %), one dominant >5 cm (41.6 %), multifocal {<=}5 (26 %), and multifocal >5 (10.4 %). Results: Overall survival at 1, 2, 3, 4, and 5 years was 93.6, 83.8, 62, 41.04, and 22.5 %, with higher rates achieved in Child class A compared with Child class B patients (95, 88.2, 61.7, 45, and 29.4 % vs. 91.5, 75, 50.7, 35.2, and 12.8 %). Mean overall survival was 43.8 months (range 1.2-64.8). Cumulative survival was better for Child class A compared with Child class B patients (p = 0.029). For patients with dominant lesions {<=}5 cm 1-, 2-, 3-, 4-, and 5-year survival rates were 100, 95.2, 71.4, 66.6, and 47.6 % for Child class A and 94.1, 88.2, 58.8, 41.2, 29.4, and 23.5 % for Child class B patients. Regarding DEB-DOX treatment, multivariate analysis identified number of lesions (p = 0.033), lesion vascularity (p < 0.0001), initially achieved complete response (p < 0.0001), and objective response (p = 0.046) as significant and independent determinants of 5-year survival. Conclusion: DEB-DOX results, with high rates of 5-year survival for patients, not amenable to curative treatments. Number of lesions, lesion vascularity, and local response were significant independent determinants of 5-year survival.

  18. For prediction of elder survival by a Gompertz model, number dead is preferable to number alive

    Easton, Dexter M.; Hirsch, Henry R.


    The standard Gompertz equation for human survival fits very poorly the survival data of the very old (age 85 and above), who appear to survive better than predicted. An alternative Gompertz model based on the number of individuals who have died, rather than the number that are alive, at each age, tracks the data more accurately. The alternative model is based on the same differential equation as in the usual Gompertz model. The standard model describes the accelerated exponential decay of the...

  19. Music in child care

    Maria Polikandrioti


    Full Text Available Music has been used therapeutically for many centuries, and numerous studies have researched the curative and preventative powers of music in several diseases. Music, as a therapy was shown to have positive effects in child care, such as in premature infants, children in emergency care, children receiving surgery, children in oncology departments and handicapped children. The aim of this review was to study the therapeutic effects of music in child care at hospital. The method οf this study included bibliography research from both the review and the research internatio nal literature, which was referred to the therapeutic effects of music in Children's Hospital. Results: Most studies focus on the beneficial effects of music to child. The results of the study showed that music is widely used to enhance well‐being and appears to exert direct effects to child, which are mainly related to physiology and psychology, including changes in the vital signs, reductions in anxiety and pain, distraction of attention from unpleasant sensations and better communication with the environment at hospital. Furthermore, music exerts indirect effects to child since is able to cause positive modifications in nurses' behaviour and conduces to better performance in their duties. Conclusions: Music consists a low-cost "therapeutic instrument" for nurses to apply to child-patient and is found to be effective in producing positive outcomes. The nurses' knowledge of music therapy need to be improved and the therapeutic impact of music must be a result from systematic professional application.

  1. Leaky Fermi accelerators

    Shah, Kushal; Rom-Kedar, Vered; Turaev, Dmitry


    A Fermi accelerator is a billiard with oscillating walls. A leaky accelerator interacts with an environment of an ideal gas at equilibrium by exchange of particles through a small hole on its boundary. Such interaction may heat the gas: we estimate the net energy flow through the hole under the assumption that the particles inside the billiard do not collide with each other and remain in the accelerator for sufficiently long time. The heat production is found to depend strongly on the type of the Fermi accelerator. An ergodic accelerator, i.e. one which has a single ergodic component, produces a weaker energy flow than a multi-component accelerator. Specifically, in the ergodic case the energy gain is independent of the hole size, whereas in the multi-component case the energy flow may be significantly increased by shrinking the hole size.

  5. Switched Matrix Accelerator

    We describe a new concept for a microwave circuit functioning as a charged-particle accelerator at mm-wavelengths, permitting an accelerating gradient higher than conventional passive circuits can withstand consistent with cyclic fatigue. The device provides acceleration for multiple bunches in parallel channels, and permits a short exposure time for the conducting surface of the accelerating cavities. Our analysis includes scalings based on a smooth transmission line model and a complementary treatment with a coupled-cavity simulation. We provide also an electromagnetic design for the accelerating structure, arriving at rough dimensions for a seven-cell accelerator matched to standard waveguide and suitable for bench tests at low power in air at 91.392. GHz. A critical element in the concept is a fast mm-wave switch suitable for operation at high-power, and we present the considerations for implementation in an H-plane tee. We discuss the use of diamond as the photoconductor switch medium

  6. Girl child and gender bias.

    Chowdhry, D P


    This article identifies gender bias against female children and youth in India. Gender bias is based on centuries-old religious beliefs and sayings from ancient times. Discrimination is reflected in denial or ignorance of female children's educational, health, nutrition, and recreational needs. Female infanticide and selective abortion of female fetuses are other forms of discrimination. The task of eliminating or reducing gender bias will involve legal, developmental, political, and administrative measures. Public awareness needs to be created. There is a need to reorient the education and health systems and to advocate for gender equality. The government of India set the following goals for the 1990s: to protect the survival of the girl child and practice safe motherhood; to develop the girl child in general; and to protect vulnerable girl children in different circumstances and in special groups. The Health Authorities should monitor the laws carefully to assure marriage after the minimum age, ban sex determination of the fetus, and monitor the health and nutrition of pre-school girls and nursing and pregnant mothers. Mothers need to be encouraged to breast feed, and to breast feed equally between genders. Every village and slum area needs a mini health center. Maternal mortality must decline. Primary health centers and hospitals need more women's wards. Education must be universally accessible. Enrollments should be increased by educating rural tribal and slum parents, reducing distances between home and school, making curriculum more relevant to girls, creating more female teachers, and providing facilities and incentives for meeting the needs of girl students. Supplementary income could be provided to families for sending girls to school. Recreational activities must be free of gender bias. Dowry, sati, and devdasi systems should be banned. PMID:12158019

  7. CAS - CERN Accelerator School: RF for Accelerators


    These proceedings present the lectures given at the twenty-fourth specialized course organized by the CERN Accelerator School (CAS). The course was held in Ebeltoft, Denmark, from 8-17 June, 2010 in collaboration with Aarhus University, with the topic 'RF for Accelerators' While this topic has been covered by CAS previously, early in the 1990s and again in 2000, it was recognized that recent advances in the field warranted an updated course. Following introductory courses covering the background physics, the course attempted to cover all aspects of RF for accelerators; from RF power generation and transport, through cavity and coupler design, electronics and low level control, to beam diagnostics and RF gymnastics. The lectures were supplemented with several sessions of exercises, which were completed by discussion sessions on the solutions.

    This report examines some properties of a new type of open accelerating structure. It consists of a series of rectangular cavities, which we call foxholes, joined by a beam channel. The power for accelerating the particles comes from an external radiation source and enters the cavities through their open upper surfaces. Analytic and computer calculations are presented showing that the foxhole is a suitable structure for accelerating relativistic electrons

    Cigno, Alessandro; Rosati, Furio Camillo; Tzannatos, Zafiris


    The causes and consequences of child labor are examined within a household decision framework with survival uncertainty and endogenous fertility. The data come from a nationally representative survey of Indian rural households. The complex interactions uncovered by the analysis suggest that mere prohibition of child labor, or the imposition of school attendance, would make things worse, and would be difficult to enforce. Beneficially reducing child labor requires changing the economic environ...

  16. Applied survival analysis using R

    Moore, Dirk F


    Applied Survival Analysis Using R covers the main principles of survival analysis, gives examples of how it is applied, and teaches how to put those principles to use to analyze data using R as a vehicle. Survival data, where the primary outcome is time to a specific event, arise in many areas of biomedical research, including clinical trials, epidemiological studies, and studies of animals. Many survival methods are extensions of techniques used in linear regression and categorical data, while other aspects of this field are unique to survival data. This text employs numerous actual examples to illustrate survival curve estimation, comparison of survivals of different groups, proper accounting for censoring and truncation, model variable selection, and residual analysis. Because explaining survival analysis requires more advanced mathematics than many other statistical topics, this book is organized with basic concepts and most frequently used procedures covered in earlier chapters, with more advanced topics...

  1. Design of survivable networks

    Stoer, Mechthild


    The problem of designing a cost-efficient network that survives the failure of one or more nodes or edges of the network is critical to modern telecommunications engineering. The method developed in this book is designed to solve such problems to optimality. In particular, a cutting plane approach is described, based on polyhedral combinatorics, that is ableto solve real-world problems of this type in short computation time. These results are of interest for practitioners in the area of communication network design. The book is addressed especially to the combinatorial optimization community, but also to those who want to learn polyhedral methods. In addition, interesting new research problemsare formulated.

  3. SURVIV for survival analysis of mRNA isoform variation.

    Shen, Shihao; Wang, Yuanyuan; Wang, Chengyang; Wu, Ying Nian; Xing, Yi


    The rapid accumulation of clinical RNA-seq data sets has provided the opportunity to associate mRNA isoform variations to clinical outcomes. Here we report a statistical method SURVIV (Survival analysis of mRNA Isoform Variation), designed for identifying mRNA isoform variation associated with patient survival time. A unique feature and major strength of SURVIV is that it models the measurement uncertainty of mRNA isoform ratio in RNA-seq data. Simulation studies suggest that SURVIV outperforms the conventional Cox regression survival analysis, especially for data sets with modest sequencing depth. We applied SURVIV to TCGA RNA-seq data of invasive ductal carcinoma as well as five additional cancer types. Alternative splicing-based survival predictors consistently outperform gene expression-based survival predictors, and the integration of clinical, gene expression and alternative splicing profiles leads to the best survival prediction. We anticipate that SURVIV will have broad utilities for analysing diverse types of mRNA isoform variation in large-scale clinical RNA-seq projects. PMID:27279334

  11. Accelerators for energy production

    A tremendous progress of accelerators for these several decades, has been motivated mainly by the research on subnuclear physics. The culmination in high energy accelerators might be SSC, 20 TeV collider in USA, probably the ultimate accelerator being built with the conventional principle. The technology cultivated and integrated for the accelerator development, can now stably offer the high power beam which could be used for the energy problems. The Inertial Confinement Fusion (ICF) with high current, 10 kA and short pulse, 20 ns heavy ion beam (HIB) of mass number ∼200, would be the most promising application of accelerators for energy production. In this scenario, the fuel containing D-T mixture, will be compressed to the high temperature, ∼10 keV and to the high density state, ∼1000 times the solid density with the pressure of ablative plasma or thermal X ray produced by bombarding of high power HIB. The efficiency, beam power/electric power for accelerator, and the repetition rate of HIB accelerators could be most suitable for the energy production. In the present paper, the outline of HIB ICF (HIF) is presented emphasizing the key issues of high current heavy ion accelerator system. (author)

  12. KEK digital accelerator

    Iwashita, T.; Adachi, T.; Takayama, K.; Leo, K. W.; Arai, T.; Arakida, Y.; Hashimoto, M.; Kadokura, E.; Kawai, M.; Kawakubo, T.; Kubo, Tomio; Koyama, K.; Nakanishi, H.; Okazaki, K.; Okamura, K.; Someya, H.; Takagi, A.; Tokuchi, A.; Wake, M.


    The High Energy Accelerator Research Organization KEK digital accelerator (KEK-DA) is a renovation of the KEK 500 MeV booster proton synchrotron, which was shut down in 2006. The existing 40 MeV drift tube linac and rf cavities have been replaced by an electron cyclotron resonance (ECR) ion source embedded in a 200 kV high-voltage terminal and induction acceleration cells, respectively. A DA is, in principle, capable of accelerating any species of ion in all possible charge states. The KEK-DA is characterized by specific accelerator components such as a permanent magnet X-band ECR ion source, a low-energy transport line, an electrostatic injection kicker, an extraction septum magnet operated in air, combined-function main magnets, and an induction acceleration system. The induction acceleration method, integrating modern pulse power technology and state-of-art digital control, is crucial for the rapid-cycle KEK-DA. The key issues of beam dynamics associated with low-energy injection of heavy ions are beam loss caused by electron capture and stripping as results of the interaction with residual gas molecules and the closed orbit distortion resulting from relatively high remanent fields in the bending magnets. Attractive applications of this accelerator in materials and biological sciences are discussed.

They were the UNK in the Soviet Union, the LHC in Europe, and the SSC in the United States. All were expected to start producing physics about 1995. They did not. Why?

  14. Accelerator for nuclear transmutation

    A review on nuclear transmutation of radioactive wastes using particle accelerators is given. Technical feasibility, nuclear data, costs of various projects are discussed. It appears that one high energy accelerator (1500 MeV, 300 mA proton) could probably handle the amount of actinides generated by the actual French nuclear program

  15. Thoughts of accelerator tubes

    A brief, subjective review is given of mechanisms that may be limiting electrostatic accelerator tubes to present levels of performance. Suggestions are made for attacking these limitations with the purpose of stimulating the thinking of designers and users of electrostatic accelerators

  16. Nuclear war survival skills

    This book includes chapters on psychological preparations, warning and communications, and evacuation. It describes the building of expedient shelters, their ventilation and cooling, the purification and storage of adequate water, the processing and cooking of whole grains and legumes, fallout meters, protection against fires and carbon monoxide, and expedient furnishings for shelters. Other chapters cover sanitation and preventive medicine, medical advice for nuclear survivors lacking the help of doctors, improvised footwear and clothing, and advice on minimum preparations that can be made at low cost and should be made before a crisis arises. One appendix of the handbook gives detailed, field-tested instructions for building six types of earth-covered expedient fallout shelters, with criteria to guide the choice of which shelter to build. Others contain instructions for making an efficient shelter-ventilating pump and a homemade fallout meter that is accurate and dependable with inexpensive materials found in most households. This report is primarily a compilation and summary of civil defense measures and inventions developed at ORNL over the past 14 years and field-tested in six states, from Florida to Utah. It is the first comprehensive handbook of survival information for use by untrained citizens who want to improve their chances of surviving a possible nuclear attack. Sections may be easily excerpted and reproduced for mass distribution through news media

  17. Child life services.


    Child life programs are an important component of pediatric hospital-based care to address the psychosocial concerns that accompany hospitalization and other health care experiences. Child life specialists focus on the optimal development and well-being of infants, children, adolescents, and young adults while promoting coping skills and minimizing the adverse effects of hospitalization, health care, and/or other potentially stressful experiences. Using therapeutic play, expressive modalities, and psychological preparation as primary tools, in collaboration with the entire health care team and family, child life interventions facilitate coping and adjustment at times and under circumstances that might otherwise prove overwhelming for the child. Play and developmentally appropriate communication are used to: (1) promote optimal development; (2) educate children and families about health conditions; (3) prepare children and families for medical events or procedures; (4) plan and rehearse useful coping and pain management strategies; (5) help children work through feelings about past or impending experiences; and (6) establish therapeutic relationships with patients, siblings, and parents to support family involvement in each child's care.

  18. Maximal Acceleration Is Nonrotating

    Page, D N


    In a stationary axisymmetric spacetime, the angular velocity of a stationary observer that Fermi-Walker transports its acceleration vector is also the angular velocity that locally extremizes the magnitude of the acceleration of such an observer, and conversely if the spacetime is also symmetric under reversing both t and phi together. Thus a congruence of Nonrotating Acceleration Worldlines (NAW) is equivalent to a Stationary Congruence Accelerating Locally Extremely (SCALE). These congruences are defined completely locally, unlike the case of Zero Angular Momentum Observers (ZAMOs), which requires knowledge around a symmetry axis. The SCALE subcase of a Stationary Congruence Accelerating Maximally (SCAM) is made up of stationary worldlines that may be considered to be locally most nearly at rest in a stationary axisymmetric gravitational field. Formulas for the angular velocity and other properties of the SCALEs are given explicitly on a generalization of an equatorial plane, infinitesimally near a symmetry...

  19. Collinear wake field acceleration

    In the Voss-Weiland scheme of wake field acceleration a high current, ring-shaped driving bunch is used to accelerate a low current beam following along on axis. In such a structure, the transformer ratio, i.e., the ratio of maximum voltage that can be gained by the on-axis beam and the voltage lost by the driving beam, can be large. In contrast, it has been observed that for an arrangement in which driving and driven bunches follow the same path, and where the current distribution of both bunches is gaussian, the transformer ratio is not normally greater than two. This paper explores some of the possibilities and limitations of a collinear acceleration scheme. In addition to its application to wake field acceleration in structures, this study is also of interest for the understanding of the plasma wake field accelerator. 11 refs., 4 figs

  20. Plasma based accelerators

    Caldwell, Allen [Max-Planck-Institut fuer Physik, Muenchen (Germany)


    The concept of laser-induced plasma wakefields as a technique to accelerate charged particles was introduced 35 years ago as a means to go beyond the accelerating gradients possible with metallic cavities supporting radio frequency electromagnetic fields. Significant developments in laser technology have made possible the pulse intensity needed to realize this concept, and rapid progress is now underway in the realization of laser-driven plasma wakefield acceleration. It has also been realized that similar accelerating gradients can be produced by particle beams propagating in plasmas, and experimental programs have also been undertaken to study this possibility. Positive results have been achieved with electron-driven plasma wakefields, and a demonstration experiment with proton-driven wakefields is under construction at CERN. The concepts behind these different schemes and their pros and cons are described, as well as the experimental results achieved. An outlook for future practical uses of plasma based accelerators will also be given.

  1. Controllable Laser Ion Acceleration

    Kawata, S.; Kamiyama, D.; Ohtake, Y.; Takano, M.; Barada, D.; Kong, Q.; Wang, P. X.; Gu, Y. J.; Wang, W. M.; Limpouch, J.; Andreev, A.; Bulanov, S. V.; Sheng, Z. M.; Klimo, O.; Psikal, J.; Ma, Y. Y.; Li, X. F.; Yu, Q. S.


    In this paper a future laser ion accelerator is discussed to make the laser-based ion accelerator compact and controllable. Especially a collimation device is focused in this paper. The future laser ion accelerator should have an ion source, ion collimators, ion beam bunchers, and ion post acceleration devices [Laser Therapy 22, 103(2013)]: the ion particle energy and the ion energy spectrum are controlled to meet requirements for a future compact laser ion accelerator for ion cancer therapy or for other purposes. The energy efficiency from the laser to ions is improved by using a solid target with a fine sub-wavelength structure or a near-critical density gas plasma. The ion beam collimation is performed by holes behind the solid target or a multi-layered solid target. The control of the ion energy spectrum and the ion particle energy, and the ion beam bunching would be successfully realized by a multistage laser-target interaction.

  2. Linear induction accelerator

    This paper examines a new layout for the injector and accelerating sectins of a linear induction accelerator. The sections are combined in a single housing: an induction system with a current-pulse generator based on double strip shaping lines laid over ferromagnetic cores; a multichannel spark discharger with forced current division among channels; and a system for core demagnetization and electron-beam formation and transport. The results of formation of an electron beam in the injector system and its acceleration in the first accelerating section of the accelerator for injection of beams with energies of 0.2-0.4 MeV, currents of 1-2 kA, and pulse durations of 60 nsec are given

  4. Acceleration of Black Hole Universe

    Zhang, Tianxi


    An alternative cosmological model called black hole universe has been recently proposed by the author. According to this model, the universe originated from a hot star-like black hole, and gradually grew up through a supermassive black hole to the present state by accreting ambient materials and merging with other black holes. The entire space is structured with an infinite number of layers hierarchically. The innermost three layers are the universe that we live, the outside space called mother universe, and the inside star-like and supermassive black holes called child universes. The outermost layer has an infinite radius and limits to zero for both the mass density and absolute temperature. All layers or universes are governed by the same physics, the Einstein general theory of relativity with the Robertson-Walker metric of space-time, and tend to expand outward physically. The evolution of the space structure is iterative. When one universe expands out, a new similar universe grows up from its inside. In this study. we will analyze the acceleration of black hole universe that accretes its ambient matter in an increasing rate. We will also compare the result obtained from the black hole universe model with the measurement of type Ia supernova and the result from the big bang cosmology.

  5. [Managing an autistic child].

    Bonnet-Brilhault, Frédérique


    General practitioners and pediatricians are on the front line to detect atypical developmental trajectories in children, They have to inform parents and to guide them toward specialized centers where further multidisciplinary evaluation will be conducted. It is admitted that early intervention is a factor of better prognosis in autism. To help starting early intervention, general practitioners may first indicate sensorymotor or language and communication evaluations. A specific project will then be defined for each child according to the results of the multidisciplinary evaluation. Each individualized project will be based on different behavioral and developpemental interventions, speech therapy, sensorymotor therapy, and psychotherapy. General practitioners and pediatricians will keep up following the child evolution as part of the child care team with parents and specialized centers. PMID:20402134

  6. Accelerated radiotherapy for advanced laryngeal cancer

    The purpose of this study was to evaluate a single institution's outcome for patients with advanced laryngeal cancer treated with accelerated radiotherapy (RT). Fifty-eight patients with advanced laryngeal cancer were treated with curative intent with accelerated RT during the period 1990-1998. Patients received radiotherapy alone or with induction chemotherapy. The 5-year local control (LC) and loco-regional control (LRC) probabilities were both 49% for T3 and 75% for T4 tumors. The 5-year disease-free survival probability was 46% and 68% and overall survival probability was 30% and 39% for T3 and T4 tumors respectively. No significant statistical difference in outcome was found, either between T3 and T4 tumors, or between patients who received induction chemotherapy and those who did not. The treatment results for advanced laryngeal cancer at this institution were comparable to those reported in the literature. The results for T3 and T4 were similar. T4 classification alone should not be an exclusion criterion for larynx preservation. Overall survival was poor, partly because of a high incidence of deaths from intercurrent diseases

  17. Cosmological magnetic field survival

    Barrow, John D


    It is widely believed that primordial magnetic fields are dramatically diluted by the expansion of the universe. As a result, cosmological magnetic fields with residual strengths of astrophysical relevance are generally sought by going outside standard cosmology, or by extending conventional electromagnetic theory. Nevertheless, the survival of strong B-fields of primordial origin is possible in spatially open Friedmann universes without changing conventional electromagnetism. The reason is the hyperbolic geometry of these spacetimes, which slows down the adiabatic magnetic decay-rate and leads to their superadiabatic amplification on large scales. So far, the effect has been found to operate on Friedmannian backgrounds containing either radiation or a slow-rolling scalar field. We show here that the superadiabatic amplification of large-scale magnetic fields, generated by quantum fluctuations during inflation, is essentially independent of the type of matter that fills the universe and appears to be a generi...

  18. The visually impaired child.

    Thompson, Lisa; Kaufman, Lawrence M


    This article discusses the causes of childhood blindness and how the primary care provider may begin the appropriate steps toward diagnosing and managing the visually impaired child. Community resources (see Box 3) and low-vision programs in schools should be used so that parents do not need to reinvent strategies to raise a blind child. Worldwide, childhood blindness, which places is a tremendous burden on families and communities of the third world, is mostly preventable with improved hygiene, diet, and immunization. PMID:12713115

  19. Accelerator programme at CAT

    The Accelerator Programme at the Centre for Advanced Technology (CAT), Indore, has very broad based concept under which all types of accelerators are to be taken up for design and fabrication. This centre will be housing a wide variety of accelerators to serve as a common facility for the universities, national laboratories in addition to laboratories under the Department of Atomic Energy. In the first phase of the programme, a series of electron accelerators are designed and fabricated. They are synchrotron radiation sources of 450 MeV (INDUS-I) and of 2 GeV (INDUS-II), microtron upto energy of 20 MeV, linear accelerator upto 20 MeV, and DC Accelerator for industrial irradiation upto 750 KeV and 20 KW. A proton accelerator of 300 MeV with 20 MeV linac injector is also designed. CAT is also developing a strong base for support technologies like ultra high vacuum, radio frequency and microwaves, DC pulsed and superconducting magnets, power supplies and controls etc. These technologies are very useful for other industrial applications also. To develop user groups to utilise INDUS-II synchrotron radiation source, a batch production of rotating Anode X-ray generators with power supplies has been initiated. So also, the sputter ion pumps, electron guns, turbo molecular pumps are brought into batch production. (author)

  20. The miniature accelerator

    Antonella Del Rosso


    The image that most people have of CERN is of its enormous accelerators and their capacity to accelerate particles to extremely high energies. But thanks to some cutting-edge studies on beam dynamics and radiofrequency technology, along with innovative construction techniques, teams at CERN have now created the first module of a brand-new accelerator, which will be just 2 metres long. The potential uses of this miniature accelerator will include deployment in hospitals for the production of medical isotopes and the treatment of cancer. It’s a real David-and-Goliath story.   Serge Mathot, in charge of the construction of the "mini-RFQ", pictured with the first of the four modules that will make up the miniature accelerator. The miniature accelerator consists of a radiofrequency quadrupole (RFQ), a component found at the start of all proton accelerator chains around the world, from the smallest to the largest. The LHC is designed to produce very high-intensity beams ...

  1. Collective ion acceleration

    Progress achieved in the understanding and development of collective ion acceleration is presented. Extensive analytic and computational studies of slow cyclotron wave growth on an electron beam in a helix amplifier were performed. Research included precise determination of linear coupling between beam and helix, suppression of undesired transients and end effects, and two-dimensional simulations of wave growth in physically realizable systems. Electrostatic well depths produced exceed requirements for the Autoresonant Ion Acceleration feasibility experiment. Acceleration of test ions to modest energies in the troughs of such waves was also demonstrated. Smaller efforts were devoted to alternative acceleration mechanisms. Langmuir wave phase velocity in Converging Guide Acceleration was calculated as a function of the ratio of electron beam current to space-charge limiting current. A new collective acceleration approach, in which cyclotron wave phase velocity is varied by modulation of electron beam voltage, is proposed. Acceleration by traveling Virtual Cathode or Localized Pinch was considered, but appears less promising. In support of this research, fundamental investigations of beam propagation in evacuated waveguides, of nonneutral beam linear eigenmodes, and of beam stability were carried out. Several computer programs were developed or enhanced. Plans for future work are discussed

  3. Large electrostatic accelerators

    Jones, C.M.


    The increasing importance of energetic heavy ion beams in the study of atomic physics, nuclear physics, and materials science has partially or wholly motivated the construction of a new generation of large electrostatic accelerators designed to operate at terminal potentials of 20 MV or above. In this paper, the author briefly discusses the status of these new accelerators and also discusses several recent technological advances which may be expected to further improve their performance. The paper is divided into four parts: (1) a discussion of the motivation for the construction of large electrostatic accelerators, (2) a description and discussion of several large electrostatic accelerators which have been recently completed or are under construction, (3) a description of several recent innovations which may be expected to improve the performance of large electrostatic accelerators in the future, and (4) a description of an innovative new large electrostatic accelerator whose construction is scheduled to begin next year. Due to time and space constraints, discussion is restricted to consideration of only tandem accelerators.

  8. Street children turn to sex-work to survive.


    The Kenyan government currently deports tourists who are caught with child prostitutes and charges the children with prostitution. A harder treatment of foreigners caught with child prostitutes may soon emerge. The Undugu Society in Kenya, an organization working with street children, welcomes such changes. It teaches children practical skills, e.g., tailoring and carpentry. The Society has four schools and sponsors 1000 children to attend school or workshops. It sends social workers into the slums to counsel and gain the trust of street children as well as to encourage them to attend workshops. The Society has workshops on HIV transmission and emphasizes behavior change rather than condom use. Kenyan law prohibits adults from having sex with a child less than 18 years old. Juvenile courts deal with children caught engaging in solicitation of customers and/or prostitution. Children found guilty go to children's homes for rehabilitation into mainstream society. More and more countries of sex-tourists are punishing tourists who engage in sexual intercourse with minors in Kenya. Fear that high-profile cases will harm the multi-million-dollar tourist industry as well as lack of state resources makes Kenya reluctant to prosecute tourists. In 1994, most of Nairobi's 40,000 street children were engaged in prostitution. The leading centers of child prostitution are all tourist areas: Nairobi, Mombasa, Malindi, Lamu, and Diani. 80% of pornographic material in Kenya features children. Kenyan taxi drivers, tour guides, and hotel workers serve as middlemen in child prostitution. Urban poverty forces many children on to the streets. Rural children sent to urban areas to work as maids or servants in a rich house are often sexually abused. They then escape to the streets. Many child prostitutes come from poor families and have low literacy and no practical skills. AIDS orphans also become prostitutes to survive. PMID:12289857

    To accommodate the observed accelerated expansion of the universe, one popular idea is to invoke a driving term in the Friedmann-Lemaitre equation of dark energy which must then comprise 70% of the present cosmological energy density. We propose an alternative interpretation which takes into account the entropy and temperature intrinsic to the horizon of the universe due to the information holographically stored there. Dark energy is thereby obviated and the acceleration is due to an entropic force naturally arising from the information storage on the horizon surface screen. We consider an additional quantitative approach inspired by surface terms in general relativity and show that this leads to the entropic accelerating universe.

    Dedicated to its goal of encouraging scientists and students to work in the field of particle accelerators, the US Particle Accelerator School (operating since 1981) has switched to a new format. Starting this year, it will offer in alternate years basic accelerator physics plus advanced subjects in both university and symposium styles over four weeks. Expanding the school from two to four weeks gives additional flexibility, and undergraduate participation should be encouraged by university credits being offered for particular courses. In the intervening years, the school will organize six-day topical courses

  13. FMIT accelerator vacuum system

    The Fusion Materials Irradiation Test (FMIT) Facility accelerator is being designed to continuously accelerate 100-mA deuterons to 25 MeV. High vacuum pumping of the accelerator structure and beam lines will be done by ion pumps and titanium sublimation pumps. The design of the roughing system includes a Roots blower/mechanical pump package. For economy the size of the system has been designed to operate at 10-6 torr, where beam particle scattering on residual gases is negligible. For minimum maintenance in this neutron factory, the FMIT vacuum system is designed from the point of view of simplicity and reliability

  14. Hadron accelerators in medicine

    The application of hadron accelerators (protons and light ions) in cancer therapy is discussed. After a brief introduction on the rationale for the use of heavy charged particles in radiation therapy, a discussion is given on accelerator technology and beam delivery systems. Next, existing and planned facilities are briefly reviewed. The Italian Hadron-therapy Project is then described in some detail, with reference ro both the National Centre for Oncological Hadron-therapy and the design of different types of compact proton accelerators aimed at introducing proton therapy in a large umber of hospitals.

  15. The auroral electron accelerator

    A model of the auroral electron acceleration process is presented in which the electrons are accelerated resonantly by lower-hybrid waves. The essentially stochastic acceleration process is approximated for the purposes of computation by a deterministic model involving an empirically derived energy transfer function. The empirical function, which is consistent with all that is known of electron energization by lower-hybrid waves, allows many, possibly all, observed features of the electron distribution to be reproduced. It is suggested that the process occurs widely in both space and laboratory plasmas. (author)

  16. Confronting Twin Paradox Acceleration

    Murphy, Thomas W.


    The resolution to the classic twin paradox in special relativity rests on the asymmetry of acceleration. Yet most students are not exposed to a satisfactory analysis of what exactly happens during the acceleration phase that results in the nonaccelerated observer's more rapid aging. The simple treatment presented here offers both graphical and quantitative solutions to the problem, leading to the correct result that the acceleration-induced age gap is 2Lβ years when the one-way distance L is expressed in light-years and velocity β ≡v/c .

  17. Auroral electron acceleration

    Two theories of auroral electron acceleration are discussed. Part 1 examines the currently widely held view that the acceleration is an ordered process in a quasi-static electric field. It is suggested that, although there are many factors seeming to support this theory, the major qualifications and uncertainties that have been identified combine to cast serious doubt over its validity. Part 2 is devoted to a relatively new interpretation in terms of stochastic acceleration in turbulent electric fields. This second theory, which appears to account readily for most known features of the electron distribution function, is considered to provide a more promising approach to this central question in magnetospheric plasma physics.

  18. Accelerated simulated tempering

    We propose a new stochastic global optimization method by accelerating the simulated tempering scheme with random walks executed on a temperature ladder with various transition step sizes. By suitably choosing the length of the transition steps, the accelerated scheme enables the search process to execute large jumps and escape entrapment in local minima, while retaining the capability to explore local details, whenever warranted. Our simulations confirm the expected improvements and show that the accelerated simulated tempering scheme has a much faster convergence to the target distribution than Geyer and Thompson's simulated tempering algorithm and exhibits accuracy comparable to the simulated annealing method

Our simulations confirm the expected improvements and show that the accelerated simulated tempering scheme has a much faster convergence to the target distribution than Geyer and Thompson's simulated tempering algorithm and exhibits accuracy comparable to the simulated annealing method.

  20. The particle accelerator

    As the Palais de la Decouverte (in Paris) is the sole scientific vulgarization establishment in the world to operate an actual particle accelerator able to provoke different types of nuclear reactions, the author recalls some historical aspects of the concerned department since the creation of the 'Radioactivity - Atom synthesis' department in 1937. He recalls the experiments which were then performed, the installation of the particle accelerator in 1964 and its renewal. He describes what's going on in this accelerator. He gives an overview of the difficulties faced after it has been decided to move it, of the works which had to be performed, and of radiation protection measures

  1. Accelerator Toolbox for MATLAB

    This paper introduces Accelerator Toolbox (AT)--a collection of tools to model particle accelerators and beam transport lines in the MATLAB environment. At SSRL, it has become the modeling code of choice for the ongoing design and future operation of the SPEAR 3 synchrotron light source. AT was designed to take advantage of power and simplicity of MATLAB--commercially developed environment for technical computing and visualization. Many examples in this paper illustrate the advantages of the AT approach and contrast it with existing accelerator code frameworks

  2. Does child abuse cause crime?

    Currie, Janet; Tekin, Erdal


    Child maltreatment, which includes both child abuse and child neglect, is a major social problem. This paper focuses on measuring the effects of child maltreatment on crime using data from the National Longitudinal Study of Adolescent Health (Add Health). We focus on crime because it is one of the most socially costly potential outcomes of maltreatment, and because the proposed mechanisms linking maltreatment and crime are relatively well elucidated in the literature. Our work addresses many ...

  15. Sociocultural determinants of infant and child mortality in Turkey.

    Aksit, B; Aksit, B


    This paper is an attempt to review and integrate international and Turkish research on infant and child mortality. Recent research and multivariate analyses in African, Latin American and Asian countries have revealed that in many countries mother's education is a powerful predictor of child survival. The present review of research in Turkey has indicated that urban/rural and regional differentials in infant mortality have been clearly established as by-products of fertility, contraception, and health surveys covering nationally representative samples. However, there are only a few multivariate explanatory models of infant/child mortality in Turkey to isolate and measure the effects of mother's education in relation to other variables. Nevertheless, existing studies in Turkey seem to suggest that mother's and father's education might link socio-economic, psychocultural, and biomedical variables with each other at community, household, and individual levels, providing clue for the formulation of future research designs and policy decisions.

  1. Patau syndrome with a long survival. A case report.

    Duarte, A C; Menezes, A I C; Devens, E S; Roth, J M; Garcias, G L; Martino-Roth, M G


    Trisomy 13 is a clinically severe entity; 85% of the patients do not survive beyond one year, and most children die before completing six months of age. We report a female child, 28 months old, white, the fourth child of a non-consanguineous couple, who presented trisomy 13. The child was born at term, from a vaginal delivery, weighing 2600 g. At birth, she was cyanotic, icteric, spastic, and cried weakly. The initial clinical examination detected polydactyly in the left hand, congenital clubfoot and convex soles, ocular hypertelorism, a low nasal bridge, numerous hemangiomas distributed throughout the body, cardiomegaly, and perimembranous inter-ventricular communication. There was no cleft lip or palate. On physical examination at 18 months old, the child weighed 6,900 g, had a cephalic perimeter of 41 cm, a thoracic perimeter of 43 cm and was 76 cm tall. At 28 months, she weighed 10,760 g and was 88.5 cm tall. Neuropsychomotor development retardation was evident from birth and, according to the psychologist and the social assistant of APAE (Handicapped Parents and Friends Association) in Canguçu, Rio Grande do Sul, there was a noticeable improvement after physiotherapy and recreational sessions.

  6. Internet and child pornography

    Seda Çağlar


    Full Text Available Nowadays, internet use and access is becoming increasingly common as a great entertainment, communication and educational resource for children as well as for adults. Internet is a perfect environment for children, for exploring the world, learning and having fun. However, access to illegal sites that contain violence and sexuality, and contact dangerous people are among the particular risks for children using the internet. It is a known fact that, internet and developing technology make the production and distribution of child pornography cheaper and easier. There has been consensus on the need of creating a plan and increasing the awareness in the community for the fight against child pornography. Because of the increasing internet use and the risk for children mentioned, nurses got new responsibilities. Nurses have to inform society, especially families and children, about safe internet use. In this review, legal regulations about the fight against child pornography on the internet, the reasons that lay the ground for child pornography and their negative effects on children has been addressed.

  14. Applicatons of accelerators

    The great diversity of possible applications of accelerators has been demonstrated in the past few years. Apart from the more familiar uses of accelerators for fundamental particle, nuclear, and solid state physics research, the applications range from microscopic trace analysis through cancer therapy to nuclear power and large volume radiation processing. Accelerators are also being used for applied research in proton radiography, radiation damage studies, laser excitation and materials analysis. The required beam properties vary from an extremely low emittance with very low beam current to megawatt beam power with a low level of beam spill. At the Chalk River Nuclear Laboratories developments are underway on applications of accelerators to nuclear fuel breeding and to cancer therapy. (author)

  18. Vibration control in accelerators

    Montag, C.


    In the vast majority of accelerator applications, ground vibration amplitudes are well below tolerable magnet jitter amplitudes. In these cases, it is necessary and sufficient to design a rigid magnet support structure that does not amplify ground vibration. Since accelerator beam lines are typically installed at an elevation of 1-2m above ground level, special care has to be taken in order to avoid designing a support structure that acts like an inverted pendulum with a low resonance frequency, resulting in untolerable lateral vibration amplitudes of the accelerator components when excited by either ambient ground motion or vibration sources within the accelerator itself, such as cooling water pumps or helium flow in superconducting magnets. In cases where ground motion amplitudes already exceed the required jiter tolerances, for instance in future linear colliders, passive vibration damping or active stabilization may be considered.

  1. A symmetrical rail accelerator

    Igenbergs, E. (Technische Univ. Muenchen, Lehrstuhl fuer Raumfahrttechnik, Richard-Wagner-Strasse 18, 8000 Muenchen 2 (DE))


    This paper reports on the symmetrical rail accelerator that has four rails, which are arranged symmetrically around the bore. The opposite rails have the same polarity and the adjacent rails the opposite polarity. In this configuration the radial force acting upon the individual rails is significantly smaller than in a conventional 2-rail configuration and a plasma armature is focussed towards the axis of the barrel. Experimental results indicate a higher efficiency compared to a conventional rail accelerator.

  2. Entropic Accelerating Universe

    Easson, Damien A.; Frampton, Paul H.; Smoot, George F.


    To accommodate the observed accelerated expansion of the universe, one popular idea is to invoke a driving term in the Friedmann-Lemaitre equation of dark energy which must then comprise 70% of the present cosmological energy density. We propose an alternative interpretation which takes into account the entropy and temperature intrinsic to the horizon of the universe due to the information holographically stored there. Dark energy is thereby obviated and the acceleration is due to an entropic...

  7. [Sugar consumption and prenatal acceleration. II. Studies on the etiology and pathophysiology of secular prenatal acceleration].

    Ziegler, E


    The pathophysiologic considerations support the causal relationship between the secular trend of sugar consumption in industrialized society and the development of prenatal acceleration, which is evident on the basis of epidemiological data. The excessive consumption of sugar and the other quickly absorbed "refined" carbohydrates enhances the hormonogenic effect of food which is also potentiated by the proteins. Together with the caloric overloading, provoked also by the excess in fat, characteristic for the affluent society, the excessive sugar consumption enhances in the pregnant women obesity and "protodiabetes" (PFEIFFER), in the predisposed child the tendency to hyperinsulinism with its consequences. In a prediabetic mother with normal glucose-tolerance the regularly repeated postprandial overfloating of the fetus with maternal glucose changes the feto-maternal hormonal regulation and enhances together with the overloading of substrate, i.e. energy and elements of biosyntheses, the accelerated fetal growth and especially the obesity of the large baby.

  9. Multimegawatt cyclotron autoresonance accelerator

    Means are discussed for generation of high-quality multimegawatt gyrating electron beams using rf gyroresonant acceleration. TE111-mode cylindrical cavities in a uniform axial magnetic field have been employed for beam acceleration since 1968; such beams have more recently been employed for generation of radiation at harmonics of the gyration frequency. Use of a TE11-mode waveguide for acceleration, rather than a cavity, is discussed. It is shown that the applied magnetic field and group velocity axial tapers allow resonance to be maintained along a waveguide, but that this is impractical in a cavity. In consequence, a waveguide cyclotron autoresonance accelerator (CARA) can operate with near-100% efficiency in power transfer from rf source to beam, while cavity accelerators will, in practice, have efficiency values limited to about 40%. CARA experiments are described in which an injected beam of up to 25 A, 95 kV has had up to 7.2 MW of rf power added, with efficiencies of up to 96%. Such levels of efficiency are higher than observed previously in any fast-wave interaction, and are competitive with efficiency values in industrial linear accelerators. Scaling arguments suggest that good quality gyrating megavolt beams with peak and average powers of 100 MW and 100 kW can be produced using an advanced CARA, with applications in the generation of high-power microwaves and for possible remediation of flue gas pollutants. copyright 1996 American Institute of Physics

  10. Accelerators for America's Future

    Bai, Mei


    Particle accelerator, a powerful tool to energize beams of charged particles to a desired speed and energy, has been the working horse for investigating the fundamental structure of matter and fundermental laws of nature. Most known examples are the 2-mile long Stanford Linear Accelerator at SLAC, the high energy proton and anti-proton collider Tevatron at FermiLab, and Large Hadron Collider that is currently under operation at CERN. During the less than a century development of accelerator science and technology that led to a dazzling list of discoveries, particle accelerators have also found various applications beyond particle and nuclear physics research, and become an indispensible part of the economy. Today, one can find a particle accelerator at almost every corner of our lives, ranging from the x-ray machine at the airport security to radiation diagnostic and therapy in hospitals. This presentation will give a brief introduction of the applications of this powerful tool in fundermental research as well as in industry. Challenges in accelerator science and technology will also be briefly presented

  11. APT accelerator technology

    The proposed accelerator production of tritium (APT) project requires an accelerator that provides a cw proton beam of 100 m A at 1300 MeV. Since the majority of the technical risk of a high-current cw (continuous-wave, 100% DF) accelerator resides in the low-energy section, Los Alamos is building a 20 MeV duplicate of the accelerator front end to confirm design codes, beam performance, and demonstrate operational reliability. We report on design details of this low-energy demonstration accelerator (LEDA) and discuss the integrated design of the full accelerator for the APT plant. LEDA's proton injector is under test and has produced more than 130 mA at 75 keV. Fabrication is proceeding on a 6.7- MeV, 8-meter-long RFQ, and detailed design is underway on coupled-cavity drift-tube linac (CCDTL) structures. In addition, detailed design and technology experiments are underway on medium-beta superconducting cavities to assess the feasibility of replacing the conventional (room-temperature copper) high-energy linac with a linac made of niobium superconducting RF cavities.

  13. Global Threats to Child Safety.

    Mace, Sharon E


    Children have rights, as enumerated in the Declaration of the Rights of the Child, and need protection from violence, exploitation, and abuse. Global threats to child safety exist. These threats include lack of basic needs (food, clean water, sanitation), maltreatment, abandonment, child labor, child marriage, female genital mutilation, child trafficking, disasters, and armed conflicts/wars. Recent disasters and armed conflicts have led to a record number of displaced people especially children and their families. Strategies and specific programs can be developed and implemented for eliminating threats to the safety of children. PMID:26613687

  14. Diffusive Shock Acceleration and Reconnection Acceleration Processes

    Zank, G. P.; Hunana, P.; Mostafavi, P.; Le Roux, J. A.; Li, Gang; Webb, G. M.; Khabarova, O.; Cummings, A.; Stone, E.; Decker, R.


    Shock waves, as shown by simulations and observations, can generate high levels of downstream vortical turbulence, including magnetic islands. We consider a combination of diffusive shock acceleration (DSA) and downstream magnetic-island-reconnection-related processes as an energization mechanism for charged particles. Observations of electron and ion distributions downstream of interplanetary shocks and the heliospheric termination shock (HTS) are frequently inconsistent with the predictions of classical DSA. We utilize a recently developed transport theory for charged particles propagating diffusively in a turbulent region filled with contracting and reconnecting plasmoids and small-scale current sheets. Particle energization associated with the anti-reconnection electric field, a consequence of magnetic island merging, and magnetic island contraction, are considered. For the former only, we find that (i) the spectrum is a hard power law in particle speed, and (ii) the downstream solution is constant. For downstream plasmoid contraction only, (i) the accelerated spectrum is a hard power law in particle speed; (ii) the particle intensity for a given energy peaks downstream of the shock, and the distance to the peak location increases with increasing particle energy, and (iii) the particle intensity amplification for a particular particle energy, f(x,c/{c}0)/f(0,c/{c}0), is not 1, as predicted by DSA, but increases with increasing particle energy. The general solution combines both the reconnection-induced electric field and plasmoid contraction. The observed energetic particle intensity profile observed by Voyager 2 downstream of the HTS appears to support a particle acceleration mechanism that combines both DSA and magnetic-island-reconnection-related processes.

  15. Family environment and child development

    Tina Kavčič


    Full Text Available The paper presents an overview of research findings on influence of family environment, especially parental behaviour, on child's development. Contemporary authors question early socialization researchers' claims that family characteristics and parental behaviour have important influence on behaviour of their children. Later researchers examined the size and durability of possible effects of family environment on child development. In addition, they focused on establishing whether it is actually the parental behaviour that influences child's development or, on the contrary, parental behaviour represents mainly a reaction to child's characteristics. Behaviour genetic studies have provided evidence that many traditional measures of family environment, including measures of parental behaviour, show genetic influence, thus reflecting genetically influenced child characteristics. Behaviour geneticists also suggest that environmental influences on child (personality development include predominantly non-shared environment, i.e. individual child's specific experiences, his/her own perceptions and interpretations of objectively same events. Based on empirically determined significant genetic effects on most behavioural traits and inconclusive results of studies on effects of family environment on child development some authors believe that it is not the parents, but rather genetic factor and/or peers who have the key role in child development. With respect to findings of behaviour genetics numerous recent studies of relations between family environment and child development involve child specific measures of (extrafamilial environment and examine the interactions between characteristics of an individual and those of his/her environment.

  16. Accelerator business in Japan expanding

    Accelerators have become to be used increasingly in Japan in such fields as medicine, physics research and industry. This has caused stiff competition for market share by the manufacturers of accelerators. Electron beam accelerators for industrial use provide an indispensable means for adding values to products, for example, electric cables with incombustible insulators. Linear accelerators for the nondestructive inspection of nuclear components have been widely installed at equipment manufacturing plants. Active efforts have been exerted to develop small synchrotron radiation accelerators for next generation electronic industry. Cyclotrons for producing short life radioisotopes for medical diagnosis and electron beam accelerators for radiation therapy are also used routinely. The suppliers of accelerators include the companies manufacturing heavy electric machinery, heavy machinery and the engineering division of steelmakers. Accelerator physics is being formed, but universities do not yet offer the course regarding accelerators. Accelerator use in Japan and the trend of accelerator manufacturers are reported. (K.I.)

  17. The Life Mission Theory IV. Theory on Child Development

    Soren Ventegodt


    Full Text Available We can identify five important needs that children have: the need for acknowledgment, acceptance, awareness or attention, respect, and care. If these needs are not met, children will modify themselves by denying central parts of their nature in order to adjust to their parents and the situation at large. When a child denies his or her talents, powers, and gender or aspects thereof, he or she loses quality of life, the ability to function, and physical or mental health. The loss of ability takes the form of diminished social ability, psychosexual potency, joy, energy, and fantasy while playing, as well as diminished ability to concentrate, focus, and learn. Many modifications result in a child with severely damaged self-confidence, self-worth, and poor performance. A child more or less deprived of self-worth cannot enjoy, give, or receive. A child deprived of emotions turns cold, rational, asocial, socially stiff, uncomfortable, and in the extreme case…... intentionally “evil”. When a child denies his or her own sex, it becomes invisible, uninteresting, and vague or becomes like the opposite sex in behavior and appearance. The general holistic solution to the vast diversity of symptoms in children with low quality of life is to improve the situation for the child and give the child the holding and support he or she needs. It is very important to realize that a negative belief often has survival value to the child as it helps the child to avoid taking responsibility for problems, which really belong to the parents or other adults. Children have a fine capability for spontaneous healing, and seem to enter this process more easily than adults, given sufficient holding. The symptoms of children with poor thriving ability are often difficult to understand, as they are caused by a complex combination of self-modification in five existential dimensions. This often leads to complex medical diagnosis, giving the idea that the child is sick and

  18. Disparities in child health in the Arab region during the 1990s

    Meyerson-Knox Sonya


    Full Text Available Abstract Background While Arab countries showed an impressive decline in child mortality rates during the past few decades, gaps in mortality by gender and socioeconomic status persisted. However, large socioeconomic disparities in child health were evident in almost every country in the region. Methods Using available tabulations and reliable micro data from national household surveys, data for 18 Arab countries were available for analysis. In addition to infant and child mortality, child health was measured by nutritional status, vaccination, and Acute Respiratory Infection (ARI. Within-country disparities in child health by gender, residence (urban/rural and maternal educational level were described. Child health was also analyzed by macro measures of development, including per capita GDP (PPP, female literacy rates, urban population and doctors per 100,000 people. Results Gender disparities in child health using the above indicators were less evident, with most showing clear female advantage. With the exception of infant and child survival, gender disparities demonstrated a female advantage, as well as a large urban advantage and an overall advantage for mothers with secondary education. Surprisingly, the countries' rankings with respect to disparities were not associated with various macro measures of development. Conclusion The tenacity of pervasive intra-country socioeconomic disparities in child health calls for attention by policy makers and health practitioners.

  19. Transcatheter arterial Chemoembolization for infiltrative hepatocellular carcinoma: Clinical safety and efficacy and factors influencing patient survival

    Han, Kichang; Kim, Jin Hyoung; Yoon, Hee Mang; Kim, Eun Joung; Gwon, Dong Il; Ko, Gi Young; Yoon, Hyun Ki; Ko, Heung Kyu [Dept. of Radiology and Research Institute of Radiology, Asan Medical Center, University of Ulsan College of Medicine, Seoul (Korea, Republic of)


    To evaluate the safety and efficacy of transcatheter arterial chemoembolization (TACE) in patients with infiltrative hepatocellular carcinoma (HCC) and to identify the prognostic factors associated with patient survival. Fifty two patients who underwent TACE for infiltrative HCC were evaluated between 2007 and 2010. The maximum diameter of the tumors ranged from 7 cm to 22 cm (median 15 cm). Of 46 infiltrative HCC patients with portal vein tumor thrombosis, 32 patients received adjuvant radiation therapy for portal vein tumor thrombosis after TACE. The tumor response by European Association for the Study of the Liver criteria was partial in 18%, stable in 47%, and progressive in 35% of the patients. The median survival time was 5.7 months (Kaplan-Meier analysis). The survival rates were 48% at six months, 25% at one year, and 12% at two years. In the multivariable Cox regression analysis, Child-Pugh class (p = 0.02), adjuvant radiotherapy (p 0.003) and tumor response after TACE (p = 0.004) were significant factors associated with patient survival. Major complications occurred in nine patients. The major complication rate was significantly higher in patients with Child-Pugh B than in patients with Child-Pugh A (p = 0.049, x{sup 2} test). Transcatheter arterial chemoembolization can be a safe treatment option in infiltrative HCC patients with Child Pugh class A. Child Pugh class A, radiotherapy for portal vein tumor thrombosis after TACE and tumor response are good prognostic factors for an increased survival after TACE in patients with infiltrative HCCs.

  20. Child mortality in a Nigerian city: its levels and socioeconomic differentials.

    Oni, G A


    Using the 'indirect' demographic estimation technique, levels of child mortality for some selected socioeconomic characteristics of mothers in Ilorin, an urban community in Nigeria, were derived. The adjusted effects of these variables on child mortality were assessed. The variables found to exert significant independent effects on child mortality included the husbands education, area of residence in the town, the parity of the mother, her use of modern contraception, availability of indoor pipe-borne water and the use of a refrigerator by the household. Reliable or useful information on child mortality in this part of Nigeria is hard to come by, hence, the estimates provided here can serve as useful baseline data for evaluating the impacts of child survival activities that are currently going on in that part of the country.

  1. Small type accelerator. Try for accelerator driven system

    Mori, Y


    FFAG (Fixed-field alternating gradient) accelerator for accelerator driven subcritical reactor, which aims to change from long-lived radioactive waste to short-lived radioactivity, is introduced. It is ring accelerator. The performance needed is proton as accelerator particle, 10MW (total) beam power, about 1GeV beam energy, >30% power efficiency and continuous beam. The feature of FFAG accelerator is constant magnetic field. PoP (Proof-of-principle)-FFAG accelerator, radial type, was run at first in Japan in 2000. The excursion is about some ten cm. In principle, beam can be injected and extracted at any place of ring. The 'multi-fish' acceleration can accelerate beams to 100% duty by repeating acceleration. 150MeV-FFAG accelerator has been started since 2001. It tried to practical use, for example, treatment of cancer. (S.Y.)

  2. Survival After Relapse of Medulloblastoma.

    Koschmann, Carl; Bloom, Karina; Upadhyaya, Santhosh; Geyer, J Russell; Leary, Sarah E S


    Survival after recurrence of medulloblastoma has not been reported in an unselected cohort of patients in the contemporary era. We reviewed 55 patients diagnosed with medulloblastoma between 2000 and 2010, and treated at Seattle Children's Hospital to evaluate patterns of relapse treatment and survival. Fourteen of 47 patients (30%) over the age of 3 experienced recurrent or progressive medulloblastoma after standard therapy. The median time from diagnosis to recurrence was 18.0 months (range, 3.6 to 62.6 mo), and site of recurrence was metastatic in 86%. The median survival after relapse was 10.3 months (range, 1.3 to 80.5 mo); 3-year survival after relapse was 18%. There were trend associations between longer survival and having received additional chemotherapy (median survival 12.8 vs. 1.3 mo, P=0.16) and radiation therapy (15.4 vs. 5.9 mo, P=0.20). Isolated local relapse was significantly associated with shorter survival (1.3 vs. 12.8 mo, P=0.009). Recurrence of medulloblastoma is more likely to be metastatic than reported in previous eras. Within the limits of our small sample, our data suggest a potential survival benefit from retreatment with cytotoxic chemotherapy and radiation even in heavily pretreated patients. This report serves as a baseline against which to evaluate novel therapy combinations. PMID:26907655

  3. Psychotherapy with children in refugee families who have survived torture

    Grünbaum, Liselotte


    Children of refugee families who have survived torture often have emotional, psychosomatic and behavioural problems as well as problems with learning. In order to understand the difficulties of these children, we have to recognize the complicated interaction of cumulative traumatic strain and...... recurring exposure to shocking violence. The traumatic experiences of the child in the country of origin take place in the broader context of chronic danger and persecution, often to be followed in the country of exile both by recurrent family strain and social estrangement. In the transference this...

  4. High energy plasma accelerators

    Colinear intense laser beams ω0, kappa0 and ω1, kappa1 shone on a plasma with frequency separation equal to the electron plasma frequency ω/sub pe/ are capable of creating a coherent large longitudinal electric field E/sub L/ = mc ω/sub pe//e of the order of 1GeV/cm for a plasma density of 1018 cm-3 through the laser beat excitation of plasma oscillations. Accompanying favorable and deleterious physical effects using this process for a high energy beat-wave accelerator are discussed: the longitudinal dephasing, pump depletion, the transverse laser diffraction, plasma turbulence effects, self-steepening, self-focusing, etc. The basic equation, the driven nonlinear Schroedinger equation, is derived to describe this system. Advanced accelerator concepts to overcome some of these problems are proposed, including the plasma fiber accelerator of various variations. An advanced laser architecture suitable for the beat-wave accelerator is suggested. Accelerator physics issues such as the luminosity are discussed. Applications of the present process to the current drive in a plasma and to the excitation of collective oscillations within nuclei are also discussed

  5. Relativistic heavy ion accelerators

    There is a growing interest in the scientific community in the use of accelerators to produce relativistic heavy ion beams for a number of purposes. It now appears that relativistic heavy ion collisions may provide an opportunity to study nuclear matter far from equilibrium density, pressure, and temperature. Heavy ion beams can also be used as simulated cosmic rays for astrophysical research and in planning space probes. At present the only relativistic heavy ion accelerator is the Belvalac at LBL. It has been devoted to this use since 1974. The operating experience and capabilities of this machine are reviewed as well as present and planned experimental programs. Designs of accelerators for relativistic heavy ions are discussed. A number of considerations will cause a machine to differ from a proton machine if optimally designed for heavy ion acceleration. A possible set of parameters is presented for an accelerator to produce intense beams of mass 10 to 200 ions, at energies up to 10 GeV/amu

  6. Dielectric laser accelerators

    England, R. Joel; Noble, Robert J.; Bane, Karl; Dowell, David H.; Ng, Cho-Kuen; Spencer, James E.; Tantawi, Sami; Wu, Ziran; Byer, Robert L.; Peralta, Edgar; Soong, Ken; Chang, Chia-Ming; Montazeri, Behnam; Wolf, Stephen J.; Cowan, Benjamin; Dawson, Jay; Gai, Wei; Hommelhoff, Peter; Huang, Yen-Chieh; Jing, Chunguang; McGuinness, Christopher; Palmer, Robert B.; Naranjo, Brian; Rosenzweig, James; Travish, Gil; Mizrahi, Amit; Schachter, Levi; Sears, Christopher; Werner, Gregory R.; Yoder, Rodney B.


    The use of infrared lasers to power optical-scale lithographically fabricated particle accelerators is a developing area of research that has garnered increasing interest in recent years. The physics and technology of this approach is reviewed, which is referred to as dielectric laser acceleration (DLA). In the DLA scheme operating at typical laser pulse lengths of 0.1 to 1 ps, the laser damage fluences for robust dielectric materials correspond to peak surface electric fields in the GV /m regime. The corresponding accelerating field enhancement represents a potential reduction in active length of the accelerator between 1 and 2 orders of magnitude. Power sources for DLA-based accelerators (lasers) are less costly than microwave sources (klystrons) for equivalent average power levels due to wider availability and private sector investment. Because of the high laser-to-particle coupling efficiency, required pulse energies are consistent with tabletop microJoule class lasers. Combined with the very high (MHz) repetition rates these lasers can provide, the DLA approach appears promising for a variety of applications, including future high-energy physics colliders, compact light sources, and portable medical scanners and radiative therapy machines.

  7. Accelerating nondiffracting beams

    Yan, Shaohui; Li, Manman; Yao, Baoli, E-mail:; Yu, Xianghua; Lei, Ming; Dan, Dan; Yang, Yanlong; Min, Junwei; Peng, Tong


    We present a set of beams which combine the properties of accelerating beams and (conventional) diffraction-free beams. These beams can travel along a desired trajectory while keeping an approximately invariant transverse profile, which may be (higher-order) Bessel-, Mathieu- or parabolic-nondiffracting-like beams, depending on the initial complex amplitude distribution. A possible application of these beams presented here may be found in optical trapping field. For example, a higher-order Bessel-like beam, which has a hollow (transverse) pattern, is suitable for guiding low-refractive-index or metal particles along a curve. - Highlights: • A set of beams having arbitrary trajectories of accelerating and nondiffracting behaviors are generalized and presented. • Bessel-like accelerating beams are generalized to the higher-order (hollow) version. • Mathieu-like accelerating beams and parabolic-nondiffracting-like accelerating beams are presented. • A possible application of these beams may be found in optical trapping and guiding of particles.

  8. Immigrant Child Poverty

    Galloway, Taryn Ann; Gustafsson, Björn; Pedersen, Peder J.;


    Immigrant and native child poverty in Denmark, Norway, and Sweden 1993–2001 is studied using large sets of panel data. While native children face yearly poverty risks of less than 10 percent in all three countries and for all years studied the increasing proportion of immigrant children...... with an origin in middle- and low-income countries have poverty risks that vary from 38 up to as much as 58 percent. At the end of the observation period, one third of the poor children in Norway and as high as about a half in Denmark and in Sweden are of immigrant origin. The strong overrepresentation...... of immigrant children from low- and middle-income countries when measured in yearly data is also found when applying a longer accounting period for poverty measurement. We find that child poverty rates are generally high shortly after arrival to the new country and typically decrease with years since...



    The Shanxi Province child labor scandal has shocked China to its core. Over 1,000 children were forced into illegal labor by morally bankrupt brick kiln businesses, throwing a depressing shroud over China’s rapid development. Uncovering these tales of abduction, death and the physical and mental abuse endured by these children has been a proud moment for China’s press. Several hundred of the kiln slave children have now been reunited with their families. Kiln owners, contractors and accomplices are being brought to justice or hunted down, some even charged with murder.However, in all this gloom some good has surfaced.Public and government attention is now focused on erasing child labor once and for all and for better protecting workers’ rights, hopefully ridding China of such disgraces in the future.

  10. A Theory of Exploitative Child Labor

    Carol Ann Rogers; Kenneth A. Swinnerton


    Child labor laws should aim to protect children who work, instead of trying to remove children from work. In this paper, we identify an instance when the risk of exploitation lowers the expected bene…t of child labor to the child,and therefore suppresses child labor force participation. Targeted legal intervention that lowers or removes the risk of exploitation raises child participation in the labor market, child welfare, and overall societal welfare. Targeting on child labor more broadly ma...

  11. Accelerators for atomic energy research

    The research and educational activities accomplished using accelerators for atomic energy research were studied. The studied items are research subjects, facility operation, the number of master theses and doctor theses on atomic energy research using accelerators and the future role of accelerators in atomic energy research. The strategy for promotion of the accelerator facility for atomic energy research is discussed. (author)

  12. Plasma-based accelerator structures

    Plasma-based accelerators have the ability to sustain extremely large accelerating gradients, with possible high-energy physics applications. This dissertation further develops the theory of plasma-based accelerators by addressing three topics: the performance of a hollow plasma channel as an accelerating structure, the generation of ultrashort electron bunches, and the propagation of laser pulses is underdense plasmas

  13. Decomposing child poverty reduction.

    Bradshaw, J.; M Huby


    European countries vary in the extent to which they succeed in reducing poverty using social transfers. However, we do not have good ways of understanding how these different outcomes are achieved. It is therefore very difficult to learn lessons from abroad. This paper uses micro data from the EU Statistics on Income and Living Condition (SILC), and attempts to decompose reductions in child poverty rates and gaps into the contribution made by children, old age, social exclusion, housing and w...

  14. Child Care Subsidy Programs

    David Blau


    Child care and early education subsidies are an important part of government efforts to increase economic independence and improve development of children in low-income families in the United States. This chapter describes the main subsidy programs in the U.S., discusses economic issues that arise in designing such programs and evaluating their effects, and surveys evidence on the effects of the programs. An important theme of the chapter is the tradeoff between the policy goals of increasing...

  15. Cohabitation and Child Wellbeing.

    Manning, Wendy D


    In recent decades, writes Wendy Manning, cohabitation has become a central part of the family landscape in the United States-so much so that by age 12, 40 percent of American children will have spent at least part of their lives in a cohabiting household. Although many children are born to cohabiting parents, and cohabiting families come in other forms as well, the most common cohabiting arrangement is a biological mother and a male partner. Cohabitation, Manning notes, is associated with several factors that have the potential to reduce children's wellbeing. Cohabiting families are more likely than married families to be poor, and poverty harms children in many ways. Cohabiting parents also tend to have less formal education-a key indicator of both economic and social resources-than married parents do. And cohabiting parent families don't have the same legal protections that married parent families have. Most importantly, cohabitation is often a marker of family instability, and family instability is strongly associated with poorer outcomes for children. Children born to cohabiting parents see their parents break up more often than do children born to married parents. In this way, being born into a cohabiting family sets the stage for later instability, and children who are born to cohabiting parents appear to experience enduring deficits of psychosocial wellbeing. On the other hand, stable cohabiting families with two biological parents seem to offer many of the same health, cognitive, and behavioral benefits that stable married biological parent families provide. Turning to stepfamilies, cohabitation's effects are tied to a child's age. Among young children, living in a cohabiting stepfamily rather than a married stepfamily is associated with more negative indicators of child wellbeing, but this is not so among adolescents. Thus the link between parental cohabitation and child wellbeing depends on both the type of cohabiting parent family and the age of the

    The problem of child labour is a deep socio-economic problem faced by almost all countries of the world. It, however, is a serious problem mostly of the developing as well as under developing countries. Infact, children particularly from low-income countries are being exploited on the global market for monetary gains. This problem also is a big social problem in India as India still falls under the category of developing nations. Various studies have made it very clear that a ...

  17. Child abuse and neglect

    Kiran, K


    Child abuse and neglect are important public health problems and recent estimates of their prevalence suggest that they are considerably more common than had hitherto been realized. Intervening to change parenting practices may, however, be important in their treatment. Despite their frequent occurrence among dental patients, neglect is the least known and identified type of abuse. The present case reports a 3-year-old girl suffering from abuse and neglect. The girl had dental neglect and als...

  18. Uniform Acceleration in General Relativity

    Friedman, Yaakov


    We extend de la Fuente and Romero's defining equation for uniform acceleration in a general curved spacetime from linear acceleration to the full Lorentz covariant uniform acceleration. In a flat spacetime background, we have explicit solutions. We use generalized Fermi-Walker transport to parallel transport the Frenet basis along the trajectory. In flat spacetime, we obtain velocity and acceleration transformations from a uniformly accelerated system to an inertial system. We obtain the time dilation between accelerated clocks. We apply our acceleration transformations to the motion of a charged particle in a constant electromagnetic field and recover the Lorentz-Abraham-Dirac equation.

  19. [Child marriage in India].

    Wen, J


    Child marriages have been practiced in India for thousands of years. Even though its popularity has now decreased due to changes in law and society, it is still a major problem, causing a great deal of hardship. Even though laws prohibited child marriage as early as 1860, statistics show that, on the average, Indians marry very young (1972: females at age 17; males at age 22 years of age; 34 females and 13 males under age 15). The following are incentives to marry young and have large families: 1) religion teaches that only those with descendants go to heaven; 2) unmarried women are traditionally scorned; and 3) most importantly, economic reasons encourage people to have large families as soon as possible, e.g., male children are encouraged to marry to obtain the dowry as soon as possible and children are considered a source of income in India. Child marriage in India causes the following problems: 1) a high infant mortality rate, as much as 75% in rural areas; 2) an imbalance in the male to female ratio (1901: 970 females/1000 males; 1971: 930 females/1000 males) because women who marry young tend to lose their health earlier; 3) a population explosion: in 1971, the Indian population was found to be increasing at the rate of 225/1000.

    Sabira S.D


    Full Text Available Child labour is conventionally defined to include all ‘economically active’ children in the age group 5-14 years. A person is treated as economically active or gainfully employed if she does work on a regular basis and receives remuneration for it. The ILO defied child labor as “work that deprives children of their childhood and their dignity, which hampers their access to education and the acquisition if skills, and which is performed under deplorable conditions harmful to their health and their development.” Child work, on the other hand, includes all paid and unpaid work for the household or for the market whether it is full time or part time. Participation in household activities on a regular basis and for several hours in a day to relieve adults for wage employment is also included in this definition. The ILO argues tat it sis not concerned with children helping in family farms or doing household chores.

  1. Child passenger safety.

    Durbin, Dennis R


    Despite significant reductions in the number of children killed in motor vehicle crashes over the past decade, crashes continue to be the leading cause of death for children 4 years and older. Therefore, the American Academy of Pediatrics continues to recommend inclusion of child passenger safety anticipatory guidance at every health-supervision visit. This technical report provides a summary of the evidence in support of 5 recommendations for best practices to optimize safety in passenger vehicles for children from birth through adolescence that all pediatricians should know and promote in their routine practice. These recommendations are presented in the revised policy statement on child passenger safety in the form of an algorithm that is intended to facilitate their implementation by pediatricians with their patients and families. The algorithm is designed to cover the majority of situations that pediatricians will encounter in practice. In addition, a summary of evidence on a number of additional issues that affect the safety of children in motor vehicles, including the proper use and installation of child restraints, exposure to air bags, travel in pickup trucks, children left in or around vehicles, and the importance of restraint laws, is provided. Finally, this technical report provides pediatricians with a number of resources for additional information to use when providing anticipatory guidance to families. PMID:21422094

  2. Superconducting Accelerator Magnets

    Mess, K H; Wolff, S


    The main topic of the book are the superconducting dipole and quadrupole magnets needed in high-energy accelerators and storage rings for protons, antiprotons or heavy ions. The basic principles of low-temperature superconductivity are outlined with special emphasis on the effects which are relevant for accelerator magnets. Properties and fabrication methods of practical superconductors are described. Analytical methods for field calculation and multipole expansion are presented for coils without and with iron yoke. The effect of yoke saturation and geometric distortions on field quality is studied. Persistent magnetization currents in the superconductor and eddy currents the copper part of the cable are analyzed in detail and their influence on field quality and magnet performance is investigated. Superconductor stability, quench origins and propagation and magnet protection are addressed. Some important concepts of accelerator physics are introduced which are needed to appreciate the demanding requirements ...

  3. Entropic Accelerating Universe

    Easson, Damien A; Smoot, George F


    To accommodate the observed accelerated expansion of the universe, one popular idea is to invoke a driving term in the Friedmann-Lema\\^{i}tre equation of dark energy which must then comprise 70% of the present cosmological energy density. We propose an alternative interpretation which takes into account the temperature intrinsic to the information holographically stored on the screen which is the surface of the universe. Dark energy is thereby obviated and the acceleration is due to an entropic force naturally arising from the information storage on a surface screen. We consider an additional quantitative approach based upon the entropy and surface terms usually neglected in General Relativity and show that this leads to the entropic accelerating universe.

  4. Superconducting accelerator magnet design

    Superconducting dipoles, quadrupoles and correction magnets are necessary to achieve the high magnetic fields required for big accelerators presently in construction or in the design phase. Different designs of superconducting accelerator magnets are described and the designs chosen at the big accelerator laboratories are presented. The most frequently used cosθ coil configuration is discussed in detail. Approaches for calculating the magnetic field quality including coil end fields are presented. Design details of the cables, coils, mechanical structures, yokes, helium vessels and cryostats including thermal radiation shields and support structures used in superconducting magnets are given. Necessary material properties are mentioned. Finally, the main results of magnetic field measurements and quench statistics are presented. (orig.)

  5. Accelerators for therapy

    In the past decades circular and linear electron accelerators have been developed for clinical use in radiation therapy of tumors with the aim of achieving a high radiation dose in the tumor and as low as possible dose in the adjacent normal tissues. Today about one thousand accelerators are in medical use throughout the world and many hundred thousand patients are treated every day with accelerator-produced radiation. There exists, however, a large number of patients who cannot be treated satisfactorily in this way. New types of radiations such as neutrons, negative pions, protons and heavy ions were therefore tested recently. The clinical experience with these radiations and with new types of treatment procedures indicate that in future the use of a scanning beam of high energy protons might be optimal for the treatment of tumors.

  6. Microelectromechanical acceleration-sensing apparatus

    Lee, Robb M.; Shul, Randy J.; Polosky, Marc A.; Hoke, Darren A.; Vernon, George E.


    An acceleration-sensing apparatus is disclosed which includes a moveable shuttle (i.e. a suspended mass) and a latch for capturing and holding the shuttle when an acceleration event is sensed above a predetermined threshold level. The acceleration-sensing apparatus provides a switch closure upon sensing the acceleration event and remains latched in place thereafter. Examples of the acceleration-sensing apparatus are provided which are responsive to an acceleration component in a single direction (i.e. a single-sided device) or to two oppositely-directed acceleration components (i.e. a dual-sided device). A two-stage acceleration-sensing apparatus is also disclosed which can sense two acceleration events separated in time. The acceleration-sensing apparatus of the present invention has applications, for example, in an automotive airbag deployment system.

  7. Studies of accelerated compact toruses

    In an earlier publication we considered acceleration of plasma rings (Compact Torus). Several possible accelerator configurations were suggested and the possibility of focusing the accelerated rings was discussed. In this paper we consider one scheme, acceleration of a ring between coaxial electrodes by a B/sub theta/ field as in a coaxial rail-gun. If the electrodes are conical, a ring accelerated towards the apex of the cone undergoes self-similar compression (focusing) during acceleration. Because the allowable acceleration force, F/sub a/ = kappaU/sub m//R where (kappa -2, the accelerating distance for conical electrodes is considerably shortened over that required for coaxial electrodes. In either case, however, since the accelerating flux can expand as the ring moves, most of the accelerating field energy can be converted into kinetic energy of the ring leading to high efficiency

  8. Girl child and social change.

    Seth, P


    This article discusses the state of social change and the disparity between India's Constitutional aims and actual practice in addressing gender inequality and the special risks of female children in India. The second part of this article summarizes Constitutional articles and laws relating to protection of women and a girl child. Before birth, a female child is at risk of fetal death. A woman is at risk of poorly performed abortions and maternal mortality. After birth, a girl child is at risk of child care of younger siblings, housework, lack of education, wage work for the household, sexual abuse, vulnerability at work or school or on the street, murder by her parents, abuse, malnutrition, and desertion. The SAARC summit declared 1990 the Year of the Girl Child. UN conventions and a world summit focused on the Rights of the Child. A child has a right to freedom from exploitation, neglect and abuse, and access to food, health care, and education. Articles 14, 15, and 16 of India's Constitution guarantee protection from discrimination on grounds of religion, race, caste, sex, or place of birth and equality of opportunity in public employment. Article 23 prohibits trafficking in humans and forced labor. Article 24 prohibits child labor under the age of 14 years. Article 39 assures an adequate means of livelihood, equal pay, and protection from child abuse and economic pressure to work in jobs unsuitable to a child's age and strength. Article 45 provides for free and compulsory education up to 14 years of age. Article 51 prohibits derogatory practices against women. Article 325 and 326 prohibits sex discrimination. Other laws pertain to dowry, marriage age, prostitution, abortion, juvenile justice, kidnapping, obscenity, procurement of a minor, sexual offenses, divorce and child support, child care, maternity benefits, and cruelty by a husband or relatives. The girl child in India continues to live in perpetual threat, both physiological and psychological. PMID

  9. CERN: Accelerator school

    Full text: Jyvaskyla, a university town in central Finland, was the setting for last year's General Accelerator School organized by the CERN Accelerator School. Well over a hundred students - more than for some time - followed two weeks of lectures on a broad spectrum of accelerator topics, the first step en route to becoming the designers, builders and operators of the surprisingly large number of, accelerators of all kinds either built or planned throughout Europe and further afield. This was the fifth such school organized by CAS in a biennial cycle which alternates this introductory level with more advanced tuition. The next, advanced, school will be from 20 October - 1 November, hosted by Athens University on the Greek Island of Rhodes. (Application details will become available in Spring but would-be participants should already reserve the dates.) After Finland, the CAS caravan moved to Benalmadena near Malaga in Spain where, together with Seville University, they organized one of the joint US-CERN schools held every two years and focusing on frontier accelerator topics. This time the subject was electron-positron factories - machines for high luminosity experiments in phi, tau-charm, beauty and Z physics. Experts from both sides of the Atlantic and from Japan shared their knowledge with an equally representative audience and probed the many intensity related phenomena which must be mastered to reach design performance. A number of these topics will receive extended coverage in the next specialist CAS School which is a repeat - by public demand - of the highly successful radiofrequency course held in Oxford in 1991. This school will be in Capri, Italy, with the support of the University of Naples from 29 April to 5 May.

  10. Nuclear Physics accelerator facilities

    The Nuclear Physics program requires the existence and effective operation of large and complex accelerator facilities. These facilities provide the variety of projectile beams upon which virtually all experimental nuclear research depends. Their capability determine which experiments can be performed and which cannot. Seven existing accelerator facilities are operated by the Nuclear Physics program as national facilities. These are made available to all the Nation's scientists on the basis of scientific merit and technical feasibility of proposals. The national facilities are the Clinton P. Anderson Meson Physics Facility (LAMPF) at Los Alamos National Laboratory; the Bates Linear Accelerator Center at Massachusetts Institute of Technology; the Bevalac at Lawrence Berkeley Laboratory; the Tandem/AGS Heavy Ion Facility at Brookhaven National Laboratory; the ATLAS facility at Argonne National Laboratory; the 88-Inch Cyclotron at Lawrence Berkeley Laboratory; the Holifield Heavy Ion Research Facility at Oak Ridge National Laboratory. The Nuclear Physics Injector at the Stanford Linear Accelerator Center (SLAC) enables the SLAC facility to provide a limited amount of beam time for nuclear physics research on the same basis as the other national facilities. To complement the national facilities, the Nuclear Physics program supports on-campus accelerators at Duke University, Texas A and M University, the University of Washington, and Yale University. The facility at Duke University, called the Triangle Universities Nuclear Laboratory (TUNL), is jointly staffed by Duke University, North Carolina State University, and the University of North Carolina. These accelerators are operated primarily for the research use of the local university faculty, junior scientists, and graduate students

  11. Child rights & child development in India: a regional analysis

    Roy, Chandan


    Being the signatory of UNCRC (1992), India globally recognized the significance of child rights. The Constitutions of India also guarantees certain child rights covering basic issues, like ‘health’, ‘education’ and protection from ‘hazardous employment’ and ‘exploitation’. However, despite the existence of many legal provisions, the vulnerability of Indian children in different dimensions cannot be undermined. This paper attempts to locate the status of child in development ladder of Indian e...

  12. How child labor and child schooling interact with adult labor

    Ray, Ranjan


    Using data from Peruvian and Pakistani household surveys, the author tests the hypotheses of a positive association between child labor hours and poverty and a negative association between child schooling and poverty. Both hypotheses are confirmed using Pakistani data but not using Peruvian data. What explains these divergent results? The link between household poverty and child labor is much stronger in Pakistan than in Peru - perhaps partly because Pakistani schools are not as good as those...

  13. Parent-Child Interaction Therapy: Enhancing Parent-Child Relationships

    Anthony J. Urquiza; Susan Timmer


    Disruptive child behavior problems are common problems for parents and can be associated with serious delinquent behaviors and aggressive/violent behaviors in adolescence and adulthood. Parenting interventions to address disruptive child behavior problems has gained widespread acceptance. One of these parenting interventions is Parent-Child Interaction Therapy (PCIT). PCIT is a 14- to 20-week, founded on social learning and attachment theories, designed for children between 2 and 7 years of a...

  14. Intermittent Sea Level Acceleration

    Olivieri, M.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Bologna, Bologna, Italia; Spada, G.; Dipartimento di Scienze di Base e Fondamenti, Università di Urbino Carlo Bo, Urbino


    Using instrumental observations from the Permanent Service for Mean Sea Level (PSMSL), we provide a new assessment of the global sea{level acceleration for the last 2 centuries (1820-2010). Our results, obtained by a stack of tide gauge time series, con firm the existence of a global sea level acceleration (GSLA) and, coherently with independent assessments so far, they point to a value close to 0:01 mm/yr2. However, di fferently from previous studies, we discuss how change points or ...

  15. Acceleration of polarized particles

    The spin kinetics of polarized beams in circular accelerators is reviewed in the case of spin-1/2 particles (electrons and protons) with emphasis on the depolarization phenomena. The acceleration of polarized proton beams in synchrotrons is described together with the cures applied to reduce depolarization, including the use of 'Siberian Snakes'. The in-situ polarization of electrons in storage rings due to synchrotron radiation is studied as well as depolarization in presence of ring imperfections. The applications of electron polarization to accurately calibrate the rings in energy and to use polarized beams in colliding-beam experiments are reviewed. (author) 76 refs., 19 figs., 1 tab

  16. Space charge wave accelerators

    We present an account of experimental observations showing control of the wave phase velocity for a slow wave, measurements of the wave electric field, and indicate how these results might apply to an ion accelerator. An interesting and new possibility is also indicated, namely the use of fast waves for electron accelerators. In this case preliminary estimates indicate that comparable field gradients to those already obtained in the slow wave scheme should be obtainable in fast waves and that these field gradients can be maintained at phase velocities close to the speed of light.

  17. High intensity hadron accelerators

    This rapporteur report consists mainly of two parts. Part I is an abridged review of the status of all High Intensity Hadron Accelerator projects in the world in semi-tabulated form for quick reference and comparison. Part II is a brief discussion of the salient features of the different technologies involved. The discussion is based mainly on my personal experiences and opinions, tempered, I hope, by the discussions I participated in in the various parallel sessions of the workshop. In addition, appended at the end is my evaluation and expression of the merits of high intensity hadron accelerators as research facilities for nuclear and particle physics

  18. Seismic surveying and accelerators

    The paper deals with an investigation into the impact of earth vibrations on charged particle beams in modern colliders. It is ascertained that the displacement of accelerator magnetic elements from the perfect position results in the excitation of betatron oscillations and distortion of particle orbit position. The results of experimental investigations into seismic noises are presented for ASR, SSC, DESY and KEK. The rms orbit displacement in accelerators is estimated relying on the law of earth diffusion motion, according to which the variance of relative displacements is proportional to the distance between these points and time of observation. 6 refs., 3 figs., 2 tabs

  19. Interfacing to accelerator instrumentation

    As the sensory system for an accelerator, the beam instrumentation provides a tremendous amount of diagnostic information. Access to this information can vary from periodic spot checks by operators to high bandwidth data acquisition during studies. In this paper, example applications will illustrate the requirements on interfaces between the control system and the instrumentation hardware. A survey of the major accelerator facilities will identify the most popular interface standards. The impact of developments such as isochronous protocols and embedded digital signal processing will also be discussed

  20. The relation between child death and child maltreatment

    Jenny, C; Isaac, R.


    The death of a child is a sentinel event in a community, and a defining marker of a society's policies of safety and health. Child death as a result of abuse and neglect is a tragic outcome that occurs in all nations of the world. The true incidence of fatal child abuse and neglect is unknown. The most accurate incidence data of such deaths have been obtained from countries where multi‐agency death review teams analyse the causes of child fatalities, as is done in the United States and Austra...

  1. Special needs and child welfare: healing the child.

    Lederman, Cindy S


    Passage of the Adoption and Safe Families Act of 1997 has placed the child at the center of the child welfare system. Courts bear the ultimate responsibility for the safety and well-being of these children, including those with disabilities. Findings from the Child and Family Service Reviews, however, indicate less-than-optimal conformity in a number of states regarding the physical and mental well-being of children. A multidisciplinary approach involving jurisprudence, science, and financing is required to bring about better compliance. Collaboration among legal, medical, dental, and child advocacy organizations is necessary for healing children in the welfare system to become a national imperative. PMID:17566535

  2. Acceleration and Focusing of Plasma Flows

    Griswold, Martin E.

    The acceleration of flowing plasmas is a fundamental problem that is useful in a wide variety of technological applications. We consider the problem from the perspective of plasma propulsion. Gridded ion thrusters and Hall thrusters are the most commonly used devices to create flowing plasma for space propulsion, but both suffer from fundamental limitations. Gridded ion sources create good quality beams in terms of energy spread and spatial divergence, but the Child-Langmuir law in the non-neutral acceleration region limits the maximum achievable current density. Hall thrusters avoid this limitation by accelerating ions in quasi-neutral plasma but, as a result, produce plumes with high spatial divergence and large energy spread. In addition the more complicated magnetized plasma in the Hall Thruster produces oscillations that can reduce the efficiency of the thruster by increasing electron transport to the anode. We present investigations of three techniques to address the fundamental limitations on the performance of each thruster. First, we propose a method to increase the time-averaged current density (and thus thrust density) produced by a gridded ion source above the Child-Langmuir limit by introducing time-varying boundary conditions. Next, we use an electrostatic plasma lens to focus the Hall thruster plume, and finally we develop a technique to suppress a prominent oscillation that degrades the performance of Hall thrusters. The technique to loosen the constraints on current density from gridded ion thrusters actually applies much more broadly to any space charge limited flow. We investigate the technique with a numerical simulation and by proving a theoretical upper bound. While we ultimately conclude that the approach is not suitable for space propulsion, our results proved useful in another area, providing a benchmark for research into the spontaneously time-dependent current that arises in microdiodes. Next, we experimentally demonstrate a novel




    The Relativistic Heavy Ion Collider (RHIC) as the first high energy polarized proton collider was designed t o provide polarized proton collisions a t a maximum beam energy of 250 GeV. I t has been providing collisions a t a beam energy of 100 Gel' since 2001. Equipped with two full Siberian snakes in each ring, polarization is preserved during the acceleration from injection to 100 GeV with careful control of the betatron tunes and the vertical orbit distortions. However, the intrinsic spin resonances beyond 100 GeV are about a factor of two stronger than those below 100 GeV? making it important t o examine the impact of these strong intrinsic spin resonances on polarization survival and the tolerance for vertical orbit distortions. Polarized protons were accelerated t o the record energy of 250 GeV in RHIC with a polarization of 46% measured a t top energy in 2006. The polarization measurement as a function of beam energy also shows some polarization loss around 136 GeV, the first strong intrinsic resonance above 100 GeV. This paper presents the results and discusses the sensitivity of the polarization survival t o orbit distortions.

  4. Accelerated hyperfractionation plus temozolomide in glioblastoma

    Hyperfractionated (HFRT) or accelerated hyperfractionated radiotherapy (AHFRT) have been discussed as a potential treatment for glioblastoma based on a hypothesized reduction of late radiation injury and prevention of repopulation. HFRT and AHFRT have been examined extensively in the pre-Temozolomide era with inconclusive results. In this study we examined the role of accelerated hyperfractionation in the Temozolomide era. Sixty-four patients who underwent AHFRT (62 of which received Temozolomide) were compared to 67 patients who underwent normofractionated radiotherapy (NFRT) (64 of which received TMZ) between 02/2009 and 10/2014. Follow-up data were analyzed until 01/2015. Median progression-free survival (PFS) was 6 months for the entire cohort. For patients treated with NFRT median PFS was 7 months, for patients treated with AHFRT median PFS was 6 months. Median overall survival (OS) was 13 months for all patients. For patients treated with NFRT median OS was 15 months, for patients treated with AHFRT median OS was 10 months. The fractionation regimen was not a predictor of PFS or OS in univariable- or multivariable analysis. There was no difference in acute toxicity profiles between the two treatment groups. Univariable and multivariable analysis did not show significant differences between NFRT and AHFRT fractionation regimens in terms of PFS or OS. The benefits are immanent: the regimen does significantly shorten hospitalization time in a patient collective with highly impaired life expectancy. We propose that the role of AHFRT + TMZ should be further examined in future prospective trials

  10. Parental health and child schooling

    Bratti, Massimiliano; Mendola, Mariapia


    Evidence on the role of parental health on child schooling is surprisingly thin. We explore this issue by estimating the short-run effects of parents\\' illness on child school enrollment. Our analysis is based on household panel data from Bosnia-Herzegovina, a country whose health and educational systems underwent extensive destruction during the 1992-1995 war. Using child fixed effects to correct for potential endogeneity bias, we find that — contrary to the common wisdom that shocks to the ...

    Fali Huang


    This paper estimates production functions of child cognitive and social development using a panel data of nine-year old children each with over two hundred home and school inputs as well as family background variables. A tree regression method is used to conduct estimation under various specifications. A small subset of inputs is found consistently important in explaining variances of child development results, including the number of books a child has at various ages and how often a mother r...

  12. Family ties and child placement.

    Colón, F


    The fundamental premise of this paper is the primacy of the child's experience of biological-familial continuity in establishing his sense of self and personal significance. This paper examines the effects of current child placement practices on the child's ties to his biological, foster, and adoptive families. It explores alternative practices that would take into account biological-familial continuity. Comment is invited. PMID:744218

  14. Child Labor and Coordination Failures

    Sylvain Dessy; Stephane Pallage


    In this paper, we show how coordination failures may explain the prevalence of child labor in developing countries. We do so within a simple game-theoretic setup. Child labor arises in our environment because of the lack of a coordination mechanism between parental decisions to invest in the human capital of their children and firm's decisions to invest in skill-intensive technology. Governmental policies that help coordinate expectations lead to the disappearance of child labor.

  16. The Supply of Child Labour

    Cigno, Alessandro


    The paper develops a theoretical framework, and a diagrammatic apparatus, for explaining the supply of child labour. It examines the effect of credit, insurance, and poverty (defined as more than just low income). It also explains bonded child labour, a modern form of slavery closely associated with the worst forms of child exploitation. The analysis is positive, but provides some of the elements for a normative judgement.
