    Baker, Michael; Milligan, Kevin

    2010-01-01

    We study the impact of maternal care on early child development using an expansion in Canadian maternity leave entitlements. Following the leave expansion, mothers who took leave spent 48-58 percent more time not working in their children's first year of life. This extra maternal care primarily crowded out home-based care by unlicensed…

  2. Maternity Leave and Mothers' Long-Term Sickness Absence: Evidence From West Germany.

    Science.gov (United States)

    Guertzgen, Nicole; Hank, Karsten

    2018-04-01

    Exploiting unique German administrative data, we estimate the association between an expansion in maternity leave duration from two to six months in 1979 and mothers' postbirth long-term sickness absence over a period of three decades after childbirth. Adopting a difference-in-difference approach, we first assess the reform's labor market effects and, subsequently, prebirth and postbirth maternal long-term sickness absence, accounting for the potential role of the reform in mothers' selection into employment. Consistent with previous research, our estimates show that the leave extension caused mothers to significantly delay their return to work within the first year after childbirth. We then provide difference-in-difference estimates for the number and length of spells of long-term sickness absence among returned mothers. Our findings suggest that among those returned, mothers subject to the leave extension exhibit a higher incidence of long-term sickness absence compared with mothers who gave birth before the reform. This also holds true after we control for observable differences in prebirth illness histories. At the same time, we find no pronounced effects on mothers' medium-run labor market attachment following the short-run delay in return to work, which might rationalize a negative causal health effect. Breaking down the results by mothers' prebirth health status suggests that the higher incidence of long-term sickness absence among mothers subject to the reform may be explained by the fact that the reform facilitated the reentry of a negative health selection into the labor market.

    2010-09-01

    We conducted a cross-sectional study of 802 Lebanese mothers to evaluate effect of rapid return to work on their health and that of their child. Breastfeeding practices were also assessed. The duration of maternity leave was insufficient for 72.8% of the women. Rapid return to work could cause physical and psychological problems depending on the type of work. The average length of breastfeeding was 4.7 months and while the average desired length was 10.9 months. Breastfeeding depended on the duration of the maternity leave, the possibility of breaks for breastfeeding and the presence of nurseries at work. Urgent interventions are necessary to prolong maternity leave and promote breastfeeding among working women.

    2010-03-01

    The social relationships of employed women on maternity leave undergo significant changes. The aim of the study was to illuminate first-time mothers' experiences of social relationships while on maternity leave. Nine mothers were interviewed at both 3-5 months and 11-14 months post-partum and the data were analyzed by means of interpretative analysis. The main theme of obtaining confirmation through social relationships was based on two themes (being confirmed by other mothers and balancing between being a mother and an employee) and on four subthemes (seeking company, sharing experiences, feeling ineffective and in a state of stagnation, and trying to handle contact with the workplace). In order to strengthen the social relationships of mothers, the mother-child health service should offer all mothers the opportunity to join a peer support group, while employers could keep in regular contact with staff members on maternity leave.

  7. The effects of California's paid family leave program on mothers' leave-taking and subsequent labor market outcomes.

    2013-01-01

    This analysis uses March Current Population Survey data from 1999 to 2010 and a differences-in-differences approach to examine how California's first in the nation paid family leave (PFL) program affected leave-taking by mothers following childbirth, as well as subsequent labor market outcomes. We obtain robust evidence that the California program doubled the overall use of maternity leave, increasing it from an average of three to six weeks for new mothers--with some evidence of particularly large growth for less advantaged groups. We also provide evidence that PFL increased the usual weekly work hours of employed mothers of 1- to 3-year-old children by 10 to 17 percent and that their wage incomes may have risen by a similar amount.

  8. Length of maternity leave and health of mother and child--a review.

    2007-01-01

    Assessment of the literature on the length of maternity leaves and health of mothers and children; evaluation of the Swiss situation in view of the maternity leave policy implemented in 2005. Review of thirteen original studies identified by PubMed using topic-related terms. A positive association was shown between the length of maternity leave and mother's mental health and duration of breastfeeding. Extended maternity leaves were also associated with lower perinatal, neonatal and post-neonatal mortality rates as well as lower child mortality; however, results are obtained in ecological studies. There is less evidence regarding other health outcomes. The new policy in Switzerland extends maternity leave for a considerable number of women to 14 weeks. With this prolongation, fewer depressive symptoms and longer breastfeeding duration can be expected, while benefits regarding other health outcomes would warrant longer leaves. Longer maternity leaves are likely to produce health benefits. The new policy in Switzerland will probably improve the situation of those women, who previously were granted only minimal leave and/or mothers with additional social risk factors.

  9. Infant sleep, parental sleep and parenting stress in families of mothers on maternity leave and in families of working mothers.

    2012-04-01

    The purpose of the present study was to investigate the links between infants' sleep and their parents' sleep and to assess the links between infant/parent sleep and parenting stress. Furthermore, we explored whether the links between sleep and parenting stress are moderated by maternal leave status. Participants were 50 families with an infant between the ages of 4-5 months. Half of the mothers were on maternity leave while the others returned to work. Parents completed daily sleep logs about infants' and their own sleep for 4 consecutive nights. Each parent also completed the Parenting Stress Index. Infant sleep was associated with sleep of both mothers and fathers, but the correlations with maternal sleep were stronger. Parental perceptions of their infant's sleep as problematic were associated with higher parenting stress. Poorer infant and maternal sleep patterns were associated with parenting stress only in families with mothers on maternity leave, probably because these mothers need to provide intensive caregiving "around the clock" without sufficient opportunities to rest.

    This study examines ways to alleviate feelings of role overload experienced by working mothers in Canada through changes to the current paid parental leave policy. Although women have made great strides in labour market participation and career development since the 1970’s, they are still maintaining the majority of childcare and household care activities, leading to difficulties balancing their roles of parent and employee. Using mothers’ blog entries from parenting websites and a comparativ...

  11. Family leave after childbirth and the mental health of new mothers.

    2012-06-01

    Recent studies indicate that short maternity leave, and, more generally, full-time maternal employment during the first year of life, detract from children's health, cognitive development, and behavioral outcomes. Much less is known, however, about how early parental employment affects the mental and physical health of the mothers themselves. The purpose of this paper is to examine the association between short family leave length (less than 12 weeks of total leave after childbirth, less than 8 weeks of paid leave) and mental and physical health outcomes among new mothers. Data come from the Early Childhood Longitudinal Study--Birth Cohort (ECLS-B), a nationally representative sample of 14,000 children born in 2001 and followed until kindergarten entry. We focus on a sample of ECLS-B mothers from the first wave of the survey who had worked during pregnancy and who had returned to work by the time of the first follow-up interview, which was conducted about 9 months after childbirth. When examining the effects of paternal leave, we further restrict this sample to mothers who were married at the time of the first follow-up interview. The maternal health outcomes of interest are measures of depression and overall health status. We use standard OLS and ordered probit models, as well as two-stage least squares and two-stage residual inclusion methods which address the potential endogeneity of family leave with respect to maternal health. Our findings from the OLS and ordered probit models indicate that, for mothers who worked prior to childbirth and who return to work in the first year, having less than 12 weeks of maternal leave and having less than 8 weeks of paid maternal leave are both associated with increases in depressive symptoms, and having less than 8 weeks of paid leave is associated with a reduction in overall health status. Findings from models that address the potential endogeneity of maternal leave generally support these results, and suggest that longer

  14. The benefits of paid maternity leave for mothers' post-partum health and wellbeing: Evidence from an Australian evaluation.

    Hewitt, Belinda; Strazdins, Lyndall; Martin, Bill

    2017-06-01

    This paper investigates the health effects of the introduction of a near universal paid parental leave (PPL) scheme in Australia, representing a natural social policy experiment. Along with gender equity and workforce engagement, a goal of the scheme (18 weeks leave at the minimum wage rate) was to enhance the health and wellbeing of mothers and babies. Although there is evidence that leave, especially paid leave, can benefit mothers' health post-partum, the potential health benefits of implementing a nationwide scheme have rarely been investigated. The data come from two cross-sectional surveys of mothers (matched on their eligibility for paid parental leave), 2347 mother's surveyed pre-PPL and 3268 post-PPL. We investigated the scheme's health benefits for mothers, and the extent this varied by pre-birth employment conditions and job characteristics. Overall, we observed better mental and physical health among mothers after the introduction of PPL, although the effects were small. Post-PPL mothers on casual (insecure) contracts before birth had significantly better mental health than their pre-PPL counterparts, suggesting that the scheme delivered health benefits to mothers who were relatively disadvantaged. However, mothers on permanent contracts and in managerial or professional occupations also had significantly better mental and physical health in the post-PPL group. These mothers were more likely to combine the Government sponsored leave with additional, paid, employer benefits, enabling a longer paid leave package post-partum. Overall, the study provides evidence that introducing paid maternity leave universally delivers health benefits to mothers. However the modest 18 week PPL provision did little to redress health inequalities. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2013-01-01

    To describe a range of employment benefits, including maternity and other paid leave, afforded to working women with infants; and to examine the geographic, socio-demographic correlates of such benefits to inform the workplace policy agenda in the US. Using data from the Listening to Mothers II Survey, a national sample of English-speaking women who gave birth in 2005, we conducted multivariable linear and logistic regression analyses to examine the associations between socio-demographic factors and employment leave variables (paid maternity, sick and personal leave). Forty-one percent of women received paid maternity leave for an average of 3.3 weeks with 31 % wage replacement. On average women took 10 weeks of maternity leave and received 10.4 days of paid sick leave and 11.6 days of paid personal time per year. Women who were non-Hispanic Black, privately insured, working full-time, and from higher income families were more likely to receive paid maternity leave, for more time, and at higher levels of wage replacement, when controlling for the other socio-demographic characteristics. Race/ethnicity, family income and employment status were associated with the number of paid personal days. Currently, the majority of female employees with young children in the US do not receive financial compensation for maternity leave and women receive limited paid leave every year to manage health-related family issues. Further, women from disadvantaged backgrounds generally receive less generous benefits. Federal policy that supports paid leave may be one avenue to address such disparities and should be modified to reflect accepted international standards. PMID:23584928

    To evaluate impacts of state Medicaid expansions for low-income parents on the health insurance coverage, pregnancy intention, and use of prenatal care among mothers who became pregnant. Person-level data for women with a live birth from the 1997-2012 Pregnancy Risk Assessment Monitoring System. The sample was restricted to women who were already parents using information on previous live births and combined with information on state Medicaid policies for low-income parents. I used a measure of expanded generosity of state Medicaid eligibility for low-income parents to estimate changes in health insurance, pregnancy intention, and prenatal care for pregnant mothers associated with Medicaid expansion. I found an increase in prepregnancy health insurance coverage and coverage during pregnancy among pregnant mothers, as well as earlier initiation of prenatal care, associated with the expansions. Among pregnant mothers with less education, I found an increase in the adequacy of prenatal care utilization. Expanded Medicaid coverage for low-income adults has the potential to increase a woman's health insurance coverage prior to pregnancy, as well as her insurance coverage and medical care receipt during pregnancy. © Health Research and Educational Trust.

    2015-09-01

    The authors investigate the relationship between family policy and women's attachment to the labor market, focusing specifically on policy feedback on women's subjective work commitment. They utilize a quasi-experimental design to identify normative policy effects from changes in mothers' work commitment in conjunction with two policy changes that significantly extended the length of statutory parental leave entitlements in Germany. Using unique survey data from the German Socio-Economic Panel and difference-in-differences, triple-differenced, and instrumental variables estimators for panel data, they obtain consistent empirical evidence that increasing generosity of leave entitlements led to a decline in mothers' work commitment in both East and West Germany. They also probe potential mediating mechanisms and find strong evidence for role exposure and norm setting effects. Finally, they demonstrate that policy-induced shifts in mothers' preferences have contributed to. retarding women's labor force participation after childbirth in Germany, especially as far as mothers' return to full-time employment is concerned.

    Full Text Available Background: Postpartum anemia among mothers is a health problem in Indonesia. Consuming Moringa Oleifera is assumed as one of the efforts to deal with anemia. However, lack of the study conducted in the working in the working area of health center of Tlogosari Wetan. Objective: This study was conducted to examine the effect of Moringa Oleifera on blood profile in postpartum mothers. Methods: The study was quasy experimental study with pretest posttest control group design. The sample in this study were all postpartum mothers in the working area of the health center of Tlogosari Wetan. It was 30 respondents recruited by purposive sampling, divided into intervention group (15 respondents who received Moringa leaf capsule and iron tablet; and control group (15 respondents were given iron tablet. Data were analyzed using Independent t-test. Results: Findings showed a significant difference in the mean of hemoglobin level (Intervention group 11.9467; control group 11.0600, hematocrit (Intervention group 38.3867; Control group 33.8133, thrombocyte (Intervention group 3.02536; Control group 2.35805, and erythrocyte (Intervention group 4.30137; Control group 3.78206 with p-value < 0.05. Conclusion: there was a significant effect of Moringa Oleifera on changes in blood profile (hemoglobin, hematocrit, erythrocyte, thrombocyte in postpartum mothers in the working area of the health center of Tlogosari Wetan. Thus, it is suggested that Moringa leaves could be used to prevent anemia in postpartum mothers.

  20. Timing matters: length of leave and working mothers' daily reentry regrets.

    2012-11-01

    Dealing with developmental tasks in work and family domains is an important challenge for young and middle-aged adults. We investigated a transition that has evolved into a normative task for women, namely, the retransition back to paid work following maternity leave. In a diary study with 149 mothers who had just returned to work, we examined the daily experienced regrets concerning this return. In addition to personal resources (i.e., emotional stability, feeling prepared for the transition) and financial requirements needed to return to work, daily experienced family stress predicted decisional regrets. Moreover, our results suggest that leave length is related to psychological resilience in the face of day-to-day stress experiences: Late returners reported fewer regrets in general and were unaffected by daily family stress. Return-to-work regrets, in turn, were predictive of withdrawal intentions. This underlines the relevancy of the timing of the transition back to work in terms of successful development during this life phase.

  2. Light-stimulated cell expansion in bean (Phaseolus vulgaris L.) leaves. I. Growth can occur without photosynthesis

    Van Volkenburgh, E.; Cleland, R. E.

    1990-01-01

    Cell expansion in dicotyledonous leaves is strongly stimulated by bright white light (WL), at least in part as a result of light-induced acidification of the cell walls. It has been proposed that photosynthetic reactions are required for light-stimulated transport processes across plasma membranes of leaf cells, including proton excretion. The involvement of photosynthesis in growth and wall acidification of primary leaves of bean has been tested by inhibiting photosynthesis in two ways: by reducing chlorophyll content of intact plants with tentoxin (TX) and by treating leaf discs with 3-(3,4-dichlorophenyl)-1,1-dimethylurea (DCMU). Exposure to bright WL stimulated growth of intact leaves of TX-treated plants. Discs excised from green as well as from TX-or DCMU-treated leaves also responded by growing faster in WL, as long as exogenous sucrose was supplied to the photosynthetically inhibited tissues. The WL caused acidification of the epidermal surface of intact TX-leaves, but acidification of the incubation medium by mesophyll cells only occurred when photosynthesis was not inhibited. It is concluded that light-stimulated cell enlargement of bean leaves, and the necessary acidification of epidermal cell walls, are mediated by a pigment other than chlorophyll. Light-induced proton excretion by mesophyll cells, on the other hand, may require both a photosynthetic product (or exogenous sugars) and a non-photosynthetic light effect.

  3. Parental leave and increased physical activity of fathers and mothers--results from the Northern Swedish Cohort.

    Physical activity is an important public health issue. Factors shown to be associated with physical activity are parenthood and country-level gender equality, while the importance of individual gender equality (in parenthood or in general) remains to explore. In Scandinavia, where parental leave can be shared equally between mothers and fathers, parental leave is one dimension of gender equality in parenthood. The aim of this study was to investigate parental leave in relation to increased physical activity among men and women. Participants in the Northern Swedish Cohort with a child born 1993-2005 (n = 584) were investigated with questionnaires at ages 21 and 42; register data on parental leave between ages 28 and 42 were obtained from Statistics Sweden. The relationships between parental leave between ages 28 and 42 and meeting WHO guidelines for physical activity at age 42, as well as changes in physical activity between ages 21 and 42, were tested with multinomial regression, controlling for socio-economic status and birth year of the child. For women, the length of parental leave was not associated with increased physical activity or with meeting WHO guidelines at age 42. For men, parental leave was associated with increased physical activity, controlling for socio-economic status and age of the child, but not with meeting WHO guidelines for physical activity at age 42. A gender non-traditional out-take of parental leave might be associated with an increase in physical activity among men at the lower end of the physical activity spectrum, but not among women. © The Author 2014.

    To investigate the association between the mother-infant relationship, defined as maternal-infant emotional attachment, maternal separation anxiety and breastfeeding, and maternal employment status at 10 months following first childbirth. Samples of employed, pregnant women, over 18 years of age and with sufficient English literacy were recruited systematically from one public and one private maternity hospital in Victoria. Data were collected by structured interview and self-report questionnaire in the third trimester, and at 3 and 10 months postpartum. Socio-demographic, employment, and breastfeeding information was collected. Participants completed standardised assessments of maternal separation anxiety and mother-to-infant emotional attachment. Of 205 eligible women, 165 (81%) agreed to participate and 129 (78%) provided complete data. A reduced odds of employment participation was independently associated with continuing to breastfeed at 10 months (OR=0.22, p=0.004) and reporting higher maternal separation anxiety (OR=0.23, p=0.01) when maternal age, education, occupational status and use of paid maternity leave and occupational status were adjusted for in analyses. Employment participation in the first 10 months postpartum is associated with lower maternal separation anxiety, and shorter breastfeeding duration. Paid parental leave has public health implications for mothers and infants. These include permitting sufficient time to protect sustained breastfeeding, and the development of optimal maternal infant attachment, reflected in confidence about separation from her infant. © 2012 The Authors.

    Reduced risk for type 1 diabetes (T1D) has been reported in the offspring of mothers with T1D when compared with children of affected fathers. To evaluate the hypothesis that exposure of the offspring to maternal insulin therapy induces regulatory mechanisms in utero, we compared the FOXP3 expressing regulatory T cells in cord blood (CB) of infants born to mothers with or without T1D. Cord blood mononuclear cells (CBMCs) from 20 infants with maternal T1D and from 20 infants with an unaffected mother were analyzed for the numbers of CD4+CD25+FOXP3+ cells ex vivo and after in vitro stimulation with human insulin by flow cytometry. The mRNA expression of FOXP3, NFATc2, STIM1, interleukin (IL)-10, and transforming growth factor (TGF)-β was measured by real-time reverse transcription polymerase chain reaction. The percentage of FOXP3+ cells in CD4+CD25(high) cells was higher in the CB of the infants with maternal T1D when compared with the infants of unaffected mothers (p = 0.023). After in vitro insulin stimulation an increase in the percentage of FOXP3+ cells in CD4+CD25(high) cells (p = 0.0002) as well as upregulation of FOXP3, NFATc2, STIM1, IL-10, and TGF-β transcripts in CBMCs (p mothers with T1D, in whom the disease-related PTPN22 allele was associated with reduced STIM1 and NFATc2 response in insulin-stimulated CBMCs (p = 0.007 and p = 0.014). We suggest that maternal insulin treatment induces expansion of regulatory T cells in the fetus, which might contribute to the lower risk of diabetes in children with maternal vs. paternal diabetes. © 2012 John Wiley & Sons A/S.

    Phytotherapy is frequently considered to be less toxic and free from side effects than synthetic drugs. Hence, the present study was designed to investigate the protective use of crude water extract of Morus alba leaves on ocular functions including cataractogenesis, biochemical diabetic and hypercholesterolemic markers, retinal neurotransmitters and retinopathy of rat pups maternally subjected to either diabetes and/or hypercholesterolemia. Application of crude water extract of Morus alba resulted in amelioration of the alterations of maternal serum glucose, LDL, HDL, total cholesterol and creatine phosphokinase activity as well as retinal neurotransmitters including acetylcholine (ACE), adrenaline (AD), nor-adrenaline (NAD), serotonin (5-HT), histamine (HS), dopamine (DA) and gamma amino butyric acid (GABA). The retina of pups of either diabetic and/or hypercholesterolemia mothers exhibited massive alterations of retinal neurotransmitters. The alterations of retinal neurotransmitters were correlated with the observed pathological alterations of retinal pigmented epithelium, photoreceptor inner segment and ganglion cells and increased incidence of DNA fragmentation and apoptosis cell death. However, protection with Morus alba extract led to amelioration of the pathological alterations of retinal neurons and estimated neurotransmitters. Furthermore, a striking incidence of cataract was detected in pups of either diabetic and/or hypercholesterolemic mothers. Highest cataractogenesis was observed in pups of combined -treated groups. Our data indicate that experimental maternal diabetes alone or in combination with hypercholesterolemia led to alteration in the ocular structures of their pups, with an increasing incidence of cataract and retinopathy, and the effects of the extract might be attributed to the hypoglycaemic, antihypercholesterolemic and anti-oxidative potential of flavonoids, the major components of the plant extract.

    2012-10-01

    In 1957 Ghana was the first sub-Saharan colonial nation-state to achieve independence from British rule. The language of literacy instruction, however, remained English throughout most of Ghana's independence, effectively thwarting reading and writing in 11 major and 67 minor indigenous languages in use today. After years of policy shifts, including the intermittent of mother tongue in early childhood schooling to facilitate English language and literacy instruction, prospects for a bold move towards multilingual education have emerged from a coalescence of forces inside and outside of Ghanaian education policy circles. This article discusses how the inertia of a dated language policy and a historic disregard for Ghana's multilingual landscape by the country's own policy makers are being overcome, at least partially, by progressive powers of change, albeit not without challenge. It undertakes an analysis of how a policy environment that supports bilingual education was created in order to implement a comprehensive and innovative multilingual programme, the National Literacy Acceleration Program (NALAP), which was rolled out across the nation's schools in early 2010. Having been involved in the process of designing NALAP, the authors describe the development of standards of learning and materials, as well as innovative aspects of a constructivist teacher education approach. The paper concludes with recommendations for further research, including combining a change process for key stakeholders and randomised language and literacy assessment with social marketing research in a unified approach.

    Breastfeeding provides numerous health benefits for infants and mothers; however, many infants are not breastfed as long as recommended or desired by mothers. Maternal employment is frequently cited as a barrier to breastfeeding. This study aimed to assess whether maternity leave duration and return status (full-time [FT], part-time [PT]) were associated with not meeting a mother's intention to breastfeed at least 3 months. We used data from the Infant Feeding Practices Study II, a cohort study. Analyses were limited to women employed prenatally who intended to breastfeed 3 months or longer (n = 1172). Multivariable logistic regression was used to assess the relationship between maternity leave duration and return-to-work status (< 6 weeks/FT, < 6 weeks/PT, 6 weeks-3 months/FT, 6 weeks-3 months/PT, not working by 3 months) and meeting a mother's intention to breastfeed at least 3 months. Overall, 28.8% of mothers did not meet their intention to breastfeed at least 3 months. Odds of not meeting intention to breastfeed at least 3 months were higher among mothers who returned to work FT before 3 months (< 6 weeks/FT: adjusted odds ratio = 2.25, 95% confidence interval, 1.23-4.12; 6 weeks-3 months/FT: adjusted odds ratio = 1.82, 95% confidence interval, 1.30-2.56), compared with mothers not working at 3 months. Returning to work full-time before 3 months may reduce a mother's ability to meet her intention to breastfeed at least 3 months. Employer support for flexible work scheduling may help more women achieve their breastfeeding goals. © International Lactation Consultant Association 2014.

    Lone mothers have to take care of a sick child with little or no help from the child’s other parent and have to carry all costs connected to leave-taking. This paper empirically tests whether lone mothers take more temporary parental leave to care for sick children than partnered mothers...... and whether parental leave is associated with a signaling cost. The results from this study of Swedish mothers show that lone mothers use more temporary parental leave than partnered mothers. Further, within the group of lone mothers, those with higher socioeconomic status take less temporary parental leave...... than those with lower socioeconomic status, whereas no such differences are found within the group of partnered mothers. One possible interpretation is that signaling costs negatively influence the utilization of temporary parental leave for lone mothers....

    The diagnosis of childhood cancer often results in an altered life situation for the parents, characterized by difficulties regarding work, family and household demands. Previous research shows that parents' work situation and income are impacted, yet, few studies have explored the issue from a longitudinal perspective. This study sought to increase the knowledge about the socio-economic conditions of parents of children with cancer in Sweden by means of a longitudinal assessment of work situation, sick leave, and household income. The sample consisted of mothers (n = 139) and fathers (n = 138) of children with cancer recruited from 2002 to 2004. Data was collected by telephone interviews at six time points, ranging from the time of diagnosis to one year after the end of treatment. Findings showed that parents' work situation was most evidently impacted during the child's treatment, when the greatest proportions of non-working and sick-listed parents were found. Compared with the time of diagnosis, fewer mothers worked up to three months after the end of treatment, and more mothers were on sick leave one year after the end of treatment. Although the extent of sick leave among fathers did not differ compared with the time of diagnosis, fewer fathers worked one year after the end of treatment. Household income was significantly reduced during the child's treatment and months thereafter, while income was at an equal level as before the diagnosis for most families one year after the end of treatment. The results offer a unique understanding of how mothers' and fathers' work situation and income are impacted in the short- and long-term, and give guidance on how to improve the comprehensive support given to parents of children with cancer. Socio-economical issues should be emphasized as these may provide targets for policy interventions aiming to reduce parental strain related to work and finances.

    Using difference-in-difference and difference-in-difference-in-difference designs, we study California's Paid Family Leave (CA-PFL) program, the first source of government-provided paid parental leave available to fathers in the Unites States. Relative to the pre-treatment mean, fathers of infants in California are 46 percent more likely to be on leave when CA-PFL is available. In households where both parents work, we find suggestive evidence that CA-PFL increases both father-only leave-taking (i.e., father on leave while mother is at work) and joint leave-taking (i.e., both parents on leave at the same time). Effects are larger for fathers of first-born children than for fathers of later-born children.

    2000-01-01

    Planning a holiday? Then if you're a member of the personnel, you'll need to use the Laboratory's new leave system that will be put in place on 1 October. Leave allocations don't change - you are entitled to just as much holiday as before - but instead of being credited annually, your leave will be credited on a monthly basis, and this information will be communicated on your salary slip. The reason for the change is that with the various new leave schemes such as Recruitment by Saved Leave (RSL) and the Progressive Retirement Programme (PRP), a streamlined procedure was required for dealing with all kinds of leave. In the new system, each member of the personnel will have leave accounts to which leave will be credited monthly from the payroll and debited each time an absence is registered in the CERN Electronic Document Handling system (EDH). Leave balances will appear on monthly pay slips, and full details of leave transactions and balances will be available through EDH at all times. As the leave will be c...

  1. Thermal expansion

    International Nuclear Information System (INIS)

    Yun, Y.

    2015-01-01

    Thermal expansion of fuel pellet is an important property which limits the lifetime of the fuels in reactors, because it affects both the pellet and cladding mechanical interaction and the gap conductivity. By fitting a number of available measured data, recommended equations have been presented and successfully used to estimate thermal expansion coefficient of the nuclear fuel pellet. However, due to large scatter of the measured data, non-consensus data have been omitted in formulating the equations. Also, the equation is strongly governed by the lack of appropriate experimental data. For those reasons, it is important to develop theoretical methodologies to better describe thermal expansion behaviour of nuclear fuel. In particular, first-principles and molecular dynamics simulations have been certainly contributed to predict reliable thermal expansion without fitting the measured data. Furthermore, the two theoretical techniques have improved on understanding the change of fuel dimension by describing the atomic-scale processes associated with lattice expansion in the fuels.

    2014-01-01

    Early return to work after childbirth has been increasing among working mothers in the US. We assessed the relationship between access to employer-offered maternity leave (EOML) (both paid and unpaid) and uptake and duration of maternity leave following childbirth in a socio-economically diverse sample of full-time working women. We focus on California, a state that has long provided more generous maternity leave benefits than those offered by federal maternity leave policies through the State Disability Insurance program. The sample included 691 mothers who gave birth in Southern California in 2002-2003. Using weighted logistic regression, we examined the EOML-maternity leave duration relationship, controlling for whether the leave was paid, as well as other occupational, personality and health-related covariates. Compared with mothers who were offered more than 12 weeks of maternity leave, mothers with leave had six times higher odds of an early return. These relationships were similar after controlling for whether the leave was paid and after controlling for other occupational and health characteristics. Access to and duration of employer-offered maternity leave significantly determine timing of return to work following childbirth, potentially affecting work-family balance. Policy makers should recognize the pivotal role of employers in offering job security during and after maternity leave and consider widening the eligibility criteria of the Family and Medical Leave Act.

    2001-09-01

    This research investigated the relationship between the length of women's maternity leave and marital incompatibility, in the context of other variables including the woman's employment, her dissatisfaction with the division of household labor, and her sense of role overload. Length of leave, work hours, and family salience were associated with several forms of dissatisfaction, which in turn predicted role overload. Role overload predicted increased marital incompatibility for experienced mothers but did not for first-time mothers, for whom discrepancies between preferred and actual child care were more important. Length of maternity leave showed significant interactions with other variables, supporting the hypothesis that a short leave is a risk factor that, when combined with another risk factor, contributes to personal and marital distress.

    Women account for the majority of parental leave take-up, which is likely one of the major reasons for the gender gap in income and wages. Consequently, many countries exert effort to promote a more gender equal division of parental leave. Indeed, the last decades have seen an increase in fathers' take-up of parental leave benefits, but the gender earnings gap has remained fairly constant. In this paper we re-evaluate the labour supply responses of both mothers and fathers to three major refo...

    1984-01-01

    Only 1 of 3 Austrian fathers involves himself daily in child rearing, and the younger the children, the less likely he is to be involved. Austria is among those European countries with the greatest pregnancy benefits. New mothers may take up to 1 year of paid maternity leave without fear of losing their jobs. This article uses 1982 Institute of Demography survey data to determine support for similar paternity leave for fathers. In the last few years, both Social Democrat and Conservative women have worked for this leave, although the movement has also found opposition by women in trade unions, as well as from conservative groups. Survey results show that 46% of married Austrian women, under age 40, favor paternity leave; 1 or 4 women can imagine their husbands taking such leave. Among husbands, 34% favored the leave option, and 1 of 4 could imagine taking the leave for a least part of the baby's first year. The study attempts to identify those husbands most likely to take advantage of paternity leave. At present, most men will not choose to stay with their children at the expense of earnings reduction. Compensation reforms for both mothers and fathers must first occur before men and women in a position to make real decisions on maternity and paternity leave.

    More women, including mothers, are part of the work force than ever before. In the workplace, barriers often exist that restrict promotion and advancement of mothers. Mothers often are penalized in attempting to meet the demands of parent and worker roles. Parenting practices have been considered primarily the domain of mothers. However, nurturing may be done effectively by fathers or other motivated adults. Policies of employers must change to accommodate needs of families. Examples of supportive practices may include flexible working hours, parental leave, and on-site child care.

    2018-05-02

    Postpartum depression affects a substantial proportion of new mothers in the United States. Although most employed women return to paid work after birth, the association between duration of maternity leave and postpartum depression is unclear. We therefore aimed to explore this relationship among mothers in the United States. Data included 177 mothers from a national survey who had returned to work full time after having a baby. Multivariable logistic regression was used to explore the independent association between duration of maternity leave and experiencing of postpartum depressive symptoms in the 2 weeks preceding the postpartum survey completion. Overall, duration of maternity leave was not significantly associated with experiencing postpartum depression symptoms (odds ratio [OR], 0.90; 95% confidence interval [CI], 0.80-1.01). This effect, however, varied by duration of maternity leave. Among women who took maternity leaves of 12 weeks or less, every additional week of leave was associated with a lesser odds of experiencing postpartum depressive symptoms (OR, 0.58; 95% CI, 0.40-0.84). Among women who took maternity leaves longer than 12 weeks, leave duration was not associated with postpartum depression symptoms (OR, 0.97; 95% CI, 0.73-1.29). Maternity leaves equaling 12 weeks or less may contribute additional risk for postpartum depressive symptoms, possibly because mothers are juggling employment alongside of important physical and emotional changes during this period. This association underscores the importance of ensuring that mothers have at least 12 weeks of leave from full-time employment after the birth of a baby.

    2017-01-01

    The role of gender in prevention of mother-to-child transmission (PMTCT) participation under Option B+ has not been adequately studied, but it is critical for reducing losses to follow-up. This study used qualitative methods to examine the interplay of gender and individual, interpersonal, health system, and community factors that contribute to PMTCT participation in Malawi and Uganda. We conducted in-depth interviews with women in PMTCT, women lost to follow-up, government health workers, and stakeholders at organizations supporting PMTCT as well as focus group discussions with men. We analyzed the data using thematic content analysis. We found many similarities in key themes across respondent groups and between the two countries. The main facilitators of PMTCT participation were knowledge of the health benefits of ART, social support, and self-efficacy. The main barriers were fear of HIV disclosure and stigma and lack of social support, male involvement, self-efficacy, and agency. Under Option B+, women learn about their HIV status and start lifelong ART on the same day, before they have a chance to talk to their husbands or families. Respondents explained that very few husbands accompanied their wives to the clinic, because they felt it was a female space and were worried that others would think their wives were controlling them. Many respondents said women fear disclosing, because they fear HIV stigma as well as the risk of divorce and loss of economic support. If women do not disclose, it is difficult for them to participate in PMTCT in secret. If they do disclose, they must abide by their husbands' decisions about their PMTCT participation, and some husbands are unsupportive or actively discouraging. To improve PMTCT participation, Ministries of Health should use evidence-based strategies to address HIV stigma, challenges related to disclosure, insufficient social support and male involvement, and underlying gender inequality.

  17. Maternity leave duration and postpartum mental and physical health: implications for leave policies.

    Dagher, Rada K; McGovern, Patricia M; Dowd, Bryan E

    2014-04-01

    This study examines the association of leave duration with depressive symptoms, mental health, physical health, and maternal symptoms in the first postpartum year, using a prospective cohort design. Eligible employed women, eighteen years or older, were interviewed in person at three Minnesota hospitals while hospitalized for childbirth in 2001. Telephone interviews were conducted at six weeks (N = 716), twelve weeks (N = 661), six months (N = 625), and twelve months (N = 575) after delivery. Depressive symptoms (Edinburgh Postnatal Depression Scale), mental and physical health (SF-12 Health Survey), and maternal childbirth-related symptoms were measured at each time period. Two-stage least squares analysis showed that the relationship between leave duration and postpartum depressive symptoms is U-shaped, with a minimum at six months. In the first postpartum year, an increase in leave duration is associated with a decrease in depressive symptoms until six months postpartum. Moreover, ordinary least squares analysis showed a marginally significant linear positive association between leave duration and physical health. Taking leave from work provides time for mothers to rest and recover from pregnancy and childbirth. Findings indicate that the current leave duration provided by the Family and Medical Leave Act, twelve weeks, may not be sufficient for mothers at risk for or experiencing postpartum depression.

    To describe the profile of women with children aged under 4 months living in the Brazilian state capitals and in the Federal District according to their working status and to analyze the influence of maternity leave on exclusive breastfeeding (EBF) among working women. This was a cross-sectional study with data extracted from the II National Maternal Breastfeeding Prevalence Survey carried out in 2008. Initially, a descriptive analysis of the profile of 12,794 women was performed, according to their working status and maternity leave and the frequency of maternity leave in the Brazilian regions and capitals. The study used a multiple model to identify the influence of maternity leave on EBF interruption, including 3766 women who declared they were working and were on maternity leave at the time of the interview. The outcome assessed in the study was the interruption of the EBF, classified by the WHO. Regarding the working status of the mothers, 63.4% did not work outside of their homes and among those who worked, 69.8% were on maternity leave. The largest prevalence among workers was of women older than 35 years of age, with more than 12 years of schooling, primiparous and from the Southeast and South regions. The lack of maternity leave increased by 23% the chance of EBF interruption. Maternity leave contributed to increase the prevalence of EBF in the Brazilian states capitals, supporting the importance of increasing the maternity leave period from four to six months.

    2013-01-01

    This analysis uses March Current Population Survey data from 1999–2010 and a differences-in-differences approach to examine how California’s first in the nation paid family leave (PFL) program affected leave-taking by mothers following childbirth, as well as subsequent labor market outcomes. We obtain robust evidence that the California program doubled the overall use of maternity leave, increasing it from an average of three to six weeks for new mothers – with some evidence of particularly large growth for less advantaged groups. We also provide evidence that PFL increased the usual weekly work hours of employed mothers of one-to-three year-old children by 10 to 17% and that their wage incomes may have risen by a similar amount.

    1997-01-01

    The recent discovery of negative thermal expansion over an unprecedented temperature range in ZrW 2 O 8 (which contracts continuously on warming from below 2 K to above 1000 K) has stimulated considerable interest in this unusual phenomenon. Negative and low thermal expansion materials have a number of important potential uses in ceramic, optical and electronic applications. We have now found negative thermal expansion in a large new family of materials with the general formula A 2 (MO 4 ) 3 . Chemical substitution dramatically influences the thermal expansion properties of these materials allowing the production of ceramics with negative, positive or zero coefficients of thermal expansion, with the potential to control other important materials properties such as refractive index and dielectric constant. The mechanism of negative thermal expansion and the phase transitions exhibited by this important new class of low-expansion materials will be discussed. (orig.)

    2017-01-01

    Abstract Over recent years many European Union countries have made changes to the design of the maternity leave provision. These policy developments reflect calls for greater gender equality in the workforce and more equal share of childcare responsibilities. However, while research shows that long period of leave can have negative effects on women's labour market attachment and career advancements, early return to work can be seen as a factor preventing exclusive breastfeeding, and therefore, potentially having negative health impacts for babies. Indeed, the World Health Organisation recommends exclusive breastfeeding up to 6 months of age to provide babies with the nutrition for healthy growth and brain development, protection from life-threatening ailments, obesity and non-communicable diseases such as asthma and diabetes. Therefore, labour market demands on women may be at odds with the health benefits for children gained by longer periods of maternity leave. The aim of this article is to examine the relationship between leave provision and health benefits for children. We examine maternity and parental leave provision across European countries and its potential impact on the breastfeeding of very young babies (up to 6-months of age). We also consider economic factors of potential extension of maternity leave provision to 6 months, such as costs to businesses, effects on the female labour market attachment, and wider consequences (benefits and costs) for individuals, families, employers and the wider society.

    To describe the problems faced by children during separation from their imprisoned mothers, and evaluate the health of children who accompanied their mothers into prison. A prospective observational study. Welikada Prison, Colombo, Sri Lanka. 200 randomly selected mothers who had left their children at home were interviewed using a questionnaire. During a period of 8 months 30 children living with their mothers in prison underwent physical and developmental examination and tuberculin testing. The living conditions within the prison were evaluated. During 18 months from January 1999, 4089 women were imprisoned. 88% were remanded, 20% awaited trial for more than one year in prison. 2416 were mothers. 1411 had at least one child under 12 years of age. The 200 mothers interviewed had 262 children under 12 years at home. Their care arrangements were: a relative (69%), father (16%), older sibling (4%), religious organisation (2.7%), neighbour (1.3%). None had received social services support. 70 children accompanied mothers into prison. In the 30 children followed up regularly 23% had scabies, 10% pediculosis, and 7% impetigo. No severe malnutrition was found and screening for tuberculosis was negative. 70% were breastfed. The child-friendly dormitory was inadequate to accommodate all children. Care arrangements and schooling were affected and no counselling services were provided during the imprisoned mothers' absence. The children within the prison enjoyed close bonds with the mothers and their physical needs were met. The child's best interest had not always been considered by court when deciding on custody during the mothers' imprisonment.

    1996-01-01

    "Since 1979 German federal maternity leave and benefit policy has given women incentives to stay at home and take care of their newborn and youngest children. In 1986 this leave and benefit policy was changed in several ways, turning it into a powerful instrument for delaying mothers' return to work after childbirth.... We estimate post childbirth return to work hazards for women during the federally protected leave protection period and immediately upon completion of this leave period. During the leave mothers are less likely to return to work the longer is the time left in the leave protection period; however, this result cannot be attributed generally to high levels of maternity benefits. When the leave protection period ends, mothers with strong labor force attachment who are still on leave return to their jobs." excerpt

  5. Fathers’ Experience of Shared Parental Leave in Sweden

    Anders Chronholm

    2011-03-01

    Full Text Available Since the introduction of the Swedish parental leave reform in 1974, fathers have had the same rights to use parental leave as mothers. Between 2000 and 2003, a research project at the Department of Sociology, University of Gothenburg, focused on fathers who had taken more than four months of paid parental leave. The approach of the study was mainly qualitative, based upon a combination of a survey and interviews. A majority of the fathers who answered the questionnaire had been the main caregivers for their children during their parental leave. During the interviews many of the men described their mothers as role models for their fatherhood. The men also described their own partner as both anxious to get back to her work after her own parental leave period and convinced of the importance of a nurturing father. An early decision to take part of the parental leave probably made it easier for the men to reach workplace agreements. Most of the men described themselves as both nurturing fathers and as sharing housework equally. They stressed the importance of being alone with their child during a long period, to be able to develop a deep relationship with their child.

    Few studies have investigated the individual long-term contributions that mothers and fathers make to their children's schooling. (1) To explore the role of early father involvement in children's later educational attainment independently of the role of early mother involvement and other confounds, (2) to investigate whether gender and family structure moderate the relationship between father's and mother's involvement and child's educational attainment, and (3) to explore whether the impact of father's involvement depends on the level of mother's involvement. The study used longitudinal data from the National Child Development Study. The initial sample were those 7,259 cohort members with valid data on mother involvement at age 7, father involvement at age 7, and school-leaving qualification by age 20. Of those, 3,303 were included in the final analysis. The measures were control variables, structural factors (family structure, sibship size and residential mobility), child factors (emotional/behavioural problems, cognitive ability and academic motivation), and father's and mother's involvement. Father involvement and mother involvement at age 7 independently predicted educational attainment by age 20. The association between parents' involvement and educational attainment was not stronger for sons than for daughters. Father involvement was not more important for educational attainment when mother involvement was low rather than high. Not growing up in intact two-parent family did not weaken the association between father's or mother's involvement and educational outcomes. Early father involvement can be another protective factor in counteracting risk conditions that might lead to later low attainment levels.

    2012-06-01

    The aim of this study was to explore the role of the paternity leave in the appearance of the maternal postpartum depression. Fifty-one couples took part in the whole study. Between the second and the fifth day after the childbirth, the mother completed the Edinburgh Postnatal Depression Scale (EPDS), which measures the symptoms of depression and the Multidimensional Scale of Perceived Social Support (MSPSS) which measures the social support the mother has become. The father completed the EPDS. Two months and then the second time four months after the childbirth, the mother received the EPDS, the MSPSS, and questionnaires measuring the temperament of the baby, the maternal skills, the feeling of being a mother and the quality of life postpartum. In order to evaluate the paternal involvement, the father completed the EPDS and questions about paternal skills and involvement. The paternity leave seemed not to have any consequences on the results at the EPDS or other questionnaires. However, lack of paternal involvement was a significant predictor of the intensity of the depressive symptoms of the mothers. It is not the presence of the father wich seems important to take into account for detection and the traitement of postpatum depression but his participation in the care of the baby.

    2016-01-01

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

We remind you that unused leave of all those taking part in the saved leave scheme at the closure of the leave year accounts is transferred automatically to the saved leave account on that date. Therefore, staff members have no administrative steps to take. In addition, the transfer, which eliminates the risk of omitting to request leave transfers and rules out calculation errors in transfer requests, will be clearly shown in the list of leave transactions that can be consulted in EDH from October 2003 onwards. Furthermore, this automatic leave transfer optimizes staff members' chances of benefiting from a saved leave bonus provided that they ar...

    Public health agencies around the world have renewed efforts to increase the incidence and duration of breastfeeding. Maternity leave mandates present an economic policy that could help achieve these goals. We study their efficacy, focusing on a significant increase in maternity leave mandates in Canada. We find very large increases in mothers' time away from work post-birth and in the attainment of critical breastfeeding duration thresholds. We also look for impacts of the reform on self-reported indicators of maternal and child health captured in our data. For most indicators we find no effect.

  17. Resonant state expansions

    International Nuclear Information System (INIS)

    Lind, P.

    1993-02-01

    The completeness properties of the discrete set of bound state, virtual states and resonances characterizing the system of a single nonrelativistic particle moving in a central cutoff potential is investigated. From a completeness relation in terms of these discrete states and complex scattering states one can derive several Resonant State Expansions (RSE). It is interesting to obtain purely discrete expansion which, if valid, would significantly simplify the treatment of the continuum. Such expansions can be derived using Mittag-Leffler (ML) theory for a cutoff potential and it would be nice to see if one can obtain the same expansions starting from an eigenfunction theory that is not restricted to a finite sphere. The RSE of Greens functions is especially important, e.g. in the continuum RPA (CRPA) method of treating giant resonances in nuclear physics. The convergence of RSE is studied in simple cases using square well wavefunctions in order to achieve high numerical accuracy. Several expansions can be derived from each other by using the theory of analytic functions and one can the see how to obtain a natural discretization of the continuum. Since the resonance wavefunctions are oscillating with an exponentially increasing amplitude, and therefore have to be interpreted through some regularization procedure, every statement made about quantities involving such states is checked by numerical calculations.Realistic nuclear wavefunctions, generated by a Wood-Saxon potential, are used to test also the usefulness of RSE in a realistic nuclear calculation. There are some fundamental differences between different symmetries of the integral contour that defines the continuum in RSE. One kind of symmetry is necessary to have an expansion of the unity operator that is idempotent. Another symmetry must be used if we want purely discrete expansions. These are found to be of the same form as given by ML. (29 refs.)

    1980-01-01

    This discourse recounts efforts put into the SNR-2 project; specifically the development of compensation devices. The various prototypes of these compensation devices are described and the state of the development reviewed. Large Na (sodium)-heat transfer systems require a lot of valuable space if the component lay-out does not include compensation devices. So, in order to condense the spatial requirement as much as possible, expansion joints must be integrated into the pipe system. There are two basic types to suit the purpose: axial expansion joints and angular expansion joints. The expansion joints were developed on the basis of specific design criteria whereby differentiation is made between expansion joints of small and large nominal diameter. Expansion joints for installation in the sodium-filled primary piping are equipped with safety bellows in addition to the actual working bellows. Expansion joints must be designed and mounted in a manner to completely withstand seismic forces. The design must exclude any damage to the bellows during intermittent operations, that is, when sodium is drained the bellows' folds must be completely empty; otherwise residual solidified sodium could destroy the bellows when restarting.

  19. Accelerating the loop expansion

    Ingermanson, R.

    1986-01-01

    This thesis introduces a new non-perturbative technique into quantum field theory. To illustrate the method, I analyze the much-studied phi 4 theory in two dimensions. As a prelude, I first show that the Hartree approximation is easy to obtain from the calculation of the one-loop effective potential by a simple modification of the propagator that does not affect the perturbative renormalization procedure. A further modification then susggests itself, which has the same nice property, and which automatically yields a convex effective potential. I then show that both of these modifications extend naturally to higher orders in the derivative expansion of the effective action and to higher orders in the loop-expansion. The net effect is to re-sum the perturbation series for the effective action as a systematic ''accelerated'' non-perturbative expansion. Each term in the accelerated expansion corresponds to an infinite number of terms in the original series. Each term can be computed explicitly, albeit numerically. Many numerical graphs of the various approximations to the first two terms in the derivative expansion are given. I discuss the reliability of the results and the problem of spontaneous symmetry-breaking, as well as some potential applications to more interesting field theories. 40 refs

  20. Virial Expansion Bounds

    Tate, Stephen James

    2013-10-01

    In the 1960s, the technique of using cluster expansion bounds in order to achieve bounds on the virial expansion was developed by Lebowitz and Penrose (J. Math. Phys. 5:841, 1964) and Ruelle (Statistical Mechanics: Rigorous Results. Benjamin, Elmsford, 1969). This technique is generalised to more recent cluster expansion bounds by Poghosyan and Ueltschi (J. Math. Phys. 50:053509, 2009), which are related to the work of Procacci (J. Stat. Phys. 129:171, 2007) and the tree-graph identity, detailed by Brydges (Phénomènes Critiques, Systèmes Aléatoires, Théories de Jauge. Les Houches 1984, pp. 129-183, 1986). The bounds achieved by Lebowitz and Penrose can also be sharpened by doing the actual optimisation and achieving expressions in terms of the Lambert W-function. The different bound from the cluster expansion shows some improvements for bounds on the convergence of the virial expansion in the case of positive potentials, which are allowed to have a hard core.

  1. Conformal expansions and renormalons

    Energy Technology Data Exchange (ETDEWEB)

    Rathsman, J.

    2000-02-07

    The coefficients in perturbative expansions in gauge theories are factorially increasing, predominantly due to renormalons. This type of factorial increase is not expected in conformal theories. In QCD conformal relations between observables can be defined in the presence of a perturbative infrared fixed-point. Using the Banks-Zaks expansion the authors study the effect of the large-order behavior of the perturbative series on the conformal coefficients. The authors find that in general these coefficients become factorially increasing. However, when the factorial behavior genuinely originates in a renormalon integral, as implied by a postulated skeleton expansion, it does not affect the conformal coefficients. As a consequence, the conformal coefficients will indeed be free of renormalon divergence, in accordance with previous observations concerning the smallness of these coefficients for specific observables. The authors further show that the correspondence of the BLM method with the skeleton expansion implies a unique scale-setting procedure. The BLM coefficients can be interpreted as the conformal coefficients in the series relating the fixed-point value of the observable with that of the skeleton effective charge. Through the skeleton expansion the relevance of renormalon-free conformal coefficients extends to real-world QCD.

    2015-01-01

    Cosmological singularities are often discussed by means of a gradient expansion that can also describe, during a quasi-de Sitter phase, the progressive suppression of curvature inhomogeneities. While the inflationary event horizon is being formed the two mentioned regimes coexist and a uniform expansion can be conceived and applied to the evolution of spatial gradients across the protoinflationary boundary. It is argued that conventional arguments addressing the preinflationary initial conditions are necessary but generally not sufficient to guarantee a homogeneous onset of the conventional inflationary stage.

It was hypothesized that (a) losses of leaf area to herbivorous invertebrates are generally greatest during leaf expansion and smaller for monocots than for dicots, and (b) where losses after expansion are appreciable any difference between monocots and dicots then is smaller than that found during expansion. Methods......: At six sites on four continents, estimates were made of lamina area loss from the four most recently mature leaves of focal monocots and of the nearest dicot shoot. Measurements of leaf mass per unit area, and the concentrations of water and nitrogen were made for many of the species. In Panama...... of leaf mass per unit area, or concentrations of water or nitrogen. At only one site was the increase in loss from first to fourth mature leaf significant (also large and the same in monocots and dicots), but the losses sustained during expansion were much smaller in the monocots.

    2005-01-01

    This conference presentation examined OPEC future capacity expansions including highlights from 2000-2004 from the supply perspective and actions by OPEC; OPEC spare capacity in 2005/2006; medium-term capacity expansion and investments; long-term scenarios, challenges and opportunities; and upstream policies in member countries. Highlights from the supply perspective included worst than expected non-OPEC supply response; non-OPEC supply affected by a number of accidents and strikes; geopolitical tensions; and higher than expected demand for OPEC crude. OPEC's actions included closer relationship with other producers and consumers; capacity expansions in 2004 and 2005/2006; and OPEC kept the market well supplied with crude in 2004. The presentation also provided data using graphical charts on OPEC net capacity additions until 2005/2006; OPEC production versus spare capacity from 2003 to 2005; OPEC production and capacity to 2010; and change in required OPEC production from 2005-2020. Medium term expansion to 2010 includes over 60 projects. Medium-term risks such as project execution, financing, costs, demand, reserves, depletion, integration of Iraq, and geopolitical tensions were also discussed. The presentation concluded that in the long term, large uncertainties remain; the peak of world supply is not imminent; and continued and enhanced cooperation is essential to market stability. tabs., figs

    2009-01-01

    Juggling breastfeeding and paid work can challenge breastfeeding success. We examined the relationship between breastfeeding and maternity leave before and after delivery among working mothers in Southern California. California is 1 of only 5 states in the United States providing paid pregnancy leave that can be extended for infant bonding. Drawing from a case-control study of preterm birth and low birth weight, 770 full-time working mothers were compared on whether they established breastfeeding in the first month. For those who established breastfeeding, we examined duration. Eligible women participated in California's Prenatal Screening Program; delivered live births between July 2002 and December 2003; were > or =18 years old; had a singleton birth without congenital anomalies; and had a US mailing address. We assessed whether maternity leave and other occupational characteristics predicted breastfeeding cessation and used multivariate regression models weighted for probability of sampling to calculate odds ratios for breastfeeding establishment and hazards ratios for breastfeeding cessation. A maternity leave of leave on breastfeeding cessation was stronger among nonmanagers, women with inflexible jobs, and with high psychosocial distress. Antenatal leave in the last month of pregnancy was not associated with breastfeeding establishment or duration. Postpartum maternity leave may have a positive effect on breastfeeding among full-time workers, particularly those who hold nonmanagerial positions, lack job flexibility, or experience psychosocial distress. Pediatricians should encourage patients to take maternity leave and advocate for extending paid postpartum leave and flexibility in working conditions for breastfeeding women.

  18. Perceptions of boundary ambiguity in the process of leaving an abusive partner.

    Khaw, Lyndal; Hardesty, Jennifer L

    2015-06-01

    The process of leaving an abusive partner has been theorized using the Stages of Change Model. Although useful, this model does not account for changes in relational boundaries unique to the process of leaving. Using family stress and feminist perspectives, this study sought to integrate boundary ambiguity into the Stages of Change Model. Boundary ambiguity is defined as a perception of uncertainty as to who is in or out of a family system (Boss & Greenberg, 1984). Twenty-five mothers who had temporarily or permanently left their abusers were interviewed. Data were analyzed using constructivist grounded theory methods. Results identify types, indicators of, and mothers' responses to boundary ambiguity throughout the five stages of change. Most mothers and abusers fluctuated between physical and psychological presence and absence over multiple separations. The integration of boundary ambiguity into the Stages of Change Model highlights the process of leaving an abusive partner as systemic, fluid, and nonlinear. © 2014 Family Process Institute.

    2000-11-01

    This study investigates whether rights to parental leave improve pediatric health. Aggregate data are used for 16 European countries over the 1969 through 1994 period. More generous paid leave is found to reduce deaths of infants and young children. The magnitudes of the estimated effects are substantial, especially where a causal effect of leave is most plausible. In particular, there is a much stronger negative relationship between leave durations and post-neonatal or child fatalities than for perinatal mortality, neonatal deaths, or low birth weight. The evidence further suggests that parental leave may be a cost-effective method of bettering child health.

    2015-09-01

    This paper investigates the effects of a large-scale paid maternity leave program on birth outcomes in the United States. In 1978, states with Temporary Disability Insurance (TDI) programs were required to start providing wage replacement benefits to pregnant women, substantially increasing access to antenatal and postnatal paid leave for working mothers. Using natality data, I find that TDI paid maternity leave reduces the share of low birth weight births by 3.2 percent, and the estimated treatment-on-the-treated effect is over 10 percent. It also decreases the likelihood of early term birth by 6.6 percent. Paid maternity leave has particularly large impacts on the children of unmarried and black mothers. Copyright © 2015 Elsevier B.V.

    1997-01-01

    The Olympic Dam orebody is the 6th largest copper and the single largest uranium orebody in the world. Mine production commenced in June 1988, at an annual production rate of around 45,000 tonnes of copper and 1,000 tonnes of uranium. Western Mining Corporation announced in 1996 a proposed $1.25 billion expansion of the Olympic Dam operation to raise the annual production capacity of the mine to 200,000 tonnes of copper, approximately 3,700 tonnes of uranium, 75,000 ounces of gold and 950,000 ounces of silver by 2001. Further optimisation work has identified a faster track expansion route, with an increase in the capital cost to $1.487 billion but improved investment outcome, a new target completion date of end 1999, and a new uranium output of 4,600 tonnes per annum from that date

    1994-01-01

    Expansion of electricity supply is associated with economic development. The installation and enlargement of power systems in developing countries entails a huge financial burden, however. Energy consumers in such countries must pay not only for supplies but for the cost of raising the capital for expansion on the international markets. Estimates are presented for the capital expenditure for electricity supply over the period 1990 to 2020 for the major world regions, using approximations for the cost of plant and capital and for the returns earned. These data lead to the conclusion that the five regions with the lowest per capita incomes are those which will need the major part of the capital expenditure and the highest percentage of external finance.

    Yamashita, Yasuho; Tanaka, Takahiro

    2016-01-01

    We discuss how the ghost-free bigravity coupled with a single scalar field can be derived from a braneworld setup. We consider DGP two-brane model without radion stabilization. The bulk configuration is solved for given boundary metrics, and it is substituted back into the action to obtain the effective four-dimensional action. In order to obtain the ghost-free bigravity, we consider the gradient expansion in which the brane separation is supposed to be sufficiently small so that two boundary metrics are almost identical. The obtained effective theory is shown to be ghost free as expected, however, the interaction between two gravitons takes the Fierz-Pauli form at the leading order of the gradient expansion, even though we do not use the approximation of linear perturbation. We also find that the radion remains as a scalar field in the four-dimensional effective theory, but its coupling to the metrics is non-trivial.

  5. Expansion of magnetic clouds

    Suess, S.T.

    1987-01-01

    Magnetic clouds are a carefully defined subclass of all interplanetary signatures of coronal mass ejections whose geometry is thought to be that of a cylinder embedded in a plane. It has been found that the total magnetic pressure inside the clouds is higher than the ion pressure outside, and that the clouds are expanding at 1 AU at about half the local Alfven speed. The geometry of the clouds is such that even though the magnetic pressure inside is larger than the total pressure outside, expansion will not occur because the pressure is balanced by magnetic tension - the pinch effect. The evidence for expansion of clouds at 1 AU is nevertheless quite strong so another reason for its existence must be found. It is demonstrated that the observations can be reproduced by taking into account the effects of geometrical distortion of the low plasma beta clouds as they move away from the Sun

    Symmetric eikonal expansion for the scattering amplitude is formulated for nonrelativistic and relativistic potential scatterings and also for the quantum field theory. The first approximations coincide with those of Levy and Sucher. The obtained scattering amplitudes are time reversal invariant for all cases and are crossing symmetric for the quantum field theory in each order of approximation. The improved eikonal phase introduced by Levy and Sucher is also derived from the different approximation scheme from the above. (auth.)

    Ludescher, K; Baumgartner, E; Roner, A; Brezinka, C

    1998-01-01

    Under Austrian law, precautionary maternity leave is a decree issued by the district public health physician. It forbids a pregnant woman to work and mandates immediate maternity leave. Regular maternity leave for all women employed in all jobs begins at 32 weeks of gestation. Women who work in workplaces deemed dangerous and women with a history of obstetric problems such as premature or growth-retarded babies from previous pregnancies are regularly 'sent' into precautionary maternity leave. The public health physicians of Tirol's nine administrative districts were interviewed and supplied data on precautionary maternity leave from their districts. In 100 women who attended the clinic for pregnancies at risk of the Obstetrics/Gynecology Department of Innsbruck University Hospital and who had already obtained precautionary maternity leave, the medical/administrative procedure was studied in each case and correlated with pregnancy outcome. The town district of Innsbruck and the district that comprises the suburbs of the provincial capital had the highest rates of precautionary maternity leave. The town district of Innsbruck had a rate of 24.3% of all pregnant women (employed and not employed) in precautionary maternity leave in 1997, whereas the whole province of Tirol had 13.4%. More than 80% of decrees for precautionary maternity leave are issued by district public health physicians on the basis of written recommendations from gynecologists. One third of women who are sent into precautionary maternity leave are issued the decree prior to 12 weeks of gestation - mostly cases of multiple pregnancies and women with previous miscarriages. The present system of precautionary maternity leave appears to work in the sense that most working pregnant women with risk factors are correctly identified - with most errors on the side of caution. As the system also helps employers - the employee's pay is paid from the federal family support fund and state insurance once she is in

    The light systems 36 Ar + 27 Al and 64 Zn + nat Ti were measured at several bombarding energies between ∼ 35 and 95 MeV/nucleon. It was found that the predominant part of the cross section is due to binary collisions. In this paper the focus is placed on the properties of the quasi-projectile nuclei. In the central collisions the excitation energies of the quasi-projectile reach values exceeding largely 10 MeV/nucleon. The slope of the high energy part of the distribution can give only an upper limit of the apparent temperature (the average temperature along the decay chain). The highly excited quasi-projectile may get rapidly fragmented rather than sequentially. The heavy fragments are excited and can emit light particles (n, p, d, t, 3 He, α,...) what perturbs additionally the spectrum of these particles. Concerning the expansion energy, one can determine the average kinetic energies of the product (in the quasi-projectile-framework) and compare with simulation values. To fit the experimental data an additional radial expansion energy is to be considered. The average expansion energy depends slightly on the impact parameter but it increases with E * / A, ranging from 0.4 to 1,2 MeV/nucleon for an excitation energy increasing from 7 to 10.5 MeV/nucleon. This collective radial energy seems to be independent of the fragment mass, what is possibly valid for the case of larger quasi-projectile masses. The origin of the expansion is to be determined. It may be due to a compression in the interaction zone at the initial stage of the collision, which propagates in the quasi-projectile and quasi-target, or else, may be due, simply, to the increase of thermal energy leading to a rapid fragment emission. The sequential de-excitation calculation overestimates light particle emission and consequently heavy residues, particularly, at higher excitation energies. This disagreement indicates that a sequential process can not account for the di-excitation of very hot nuclei

    A free standing self contained device for bonding ultra thin metallic films, such as 0.001 inch beryllium foils is disclosed. The device will regulate to a predetermined load for solid state bonding when heated to a bonding temperature. The device includes a load regulating feature, whereby the expansion stresses generated for bonding are regulated and self adjusting. The load regulator comprises a pair of friction isolators with a plurality of annealed copper members located there between. The device, with the load regulator, will adjust to and maintain a stress level needed to successfully and economically complete a leak tight bond without damaging thin foils or other delicate components. 1 fig

    1978-04-01

    The thermal expansion of rocks is strongly controlled by the thermal expansion of the minerals. The theoretical thermal expansion of the Stripa Granite is gound to be 21 . 10 -6 [deg C] -1 at 25 deg C and 38 . 10 -6 [deg C] -1 at 400 deg C. The difference in expansion for the rock forming minerals causes micro cracking at heating. The expansion due to micro cracks is found to be of the same order as the mineral expansion. Most of the micro cracks will close at pressures of the order of 10 - 20 MPa. The thermal expansion of a rock mass including the effect of joints is determined in the pilot heater test in the Stripa Mine

  2. Provincial hydro expansions

    Energy Technology Data Exchange (ETDEWEB)

    Froschauer, K J

    1993-01-01

    A study of the development of five provincial hydroelectric utilities in Canada indicates that power companies and the state invited manufacturers to use hydroelectricity and natural resources in order to diversify provincial economies. These hydro expansions also show that utilities and government designed hydro projects to serve continental requirements; serving both objectives became problematic. It is argued that when the Canadian state and firms such as utilities use hydro expansions to serve both continentalism and industrialization, then at best they foster dependent industrialization and staple processing. At worst, they overbuild the infrastructure to generate provincial surplus energy for continental, rather than national, integration. Hydro developments became subject to state intervention in Canada mainly through the failures of private utilities to provide power for the less-lucrative industrial markets within provincial subregions. Although the state and utilities invited foreign firms to manufacture hydro equipment within the provinces and others to use electricity to diversify production beyond resource processing, such a diversification did not occur. Since 1962, ca 80% of industrial energy was used to semi-process wood-derived products, chemicals, and metals. The idea for a national power network became undermined by interprovincial political-economic factors and since 1963, the federal national/continential power policy prevailed. 187 refs., 6 figs., 52 tabs.

  3. Measuring of tube expansion

    International Nuclear Information System (INIS)

    Vogeleer, J. P.

    1985-01-01

    The expansion of the primary tubes or sleeves of the steam generator of a nuclear reactor plant are measured while the tubes or sleeves are being expanded. A primary tube or sleeve is expanded by high pressure of water which flows through a channel in an expander body. The water is supplied through an elongated conductor and is introduced through a connector on the shank connected to the conductor at its outer end. A wire extends through the mandrel and through the conductor to the end of the connector. At its inner end the wire is connected to a tapered pin which is subject to counteracting forces produced by the pressure of the water. The force on the side where the wire is connected to the conductor is smaller than on the opposite side. The tapered pin is moved in the direction of the higher force and extrudes the wire outwardly of the conductor. The tapered surface of the tapered pin engages transverse captive plungers which are maintained in engagement with the expanding tube or sleeve as they are moved outwardly by the tapered pin. The wire and the connector extend out of the generator and, at its outer end, the wire is connected to an indicator which measures the extent to which the wire is moved by the tapered pin, thus measuring the expansion of the tube or sleeve as it progresses

    As part of the process of streamlining procedures, the HR and AS Divisions have jointly developed a system whereby annual and compensatory leave will henceforth be automatically transferred1) to saved leave accounts. Under the provisions of the voluntary saved leave scheme (SLS), a maximum total of 10 days'2)Previously, every person taking part in the scheme has been individually issued with a form for the purposes of requesting the transfer of leave to the leave account and the transfer has then had to be done manually by HR Division. To streamline the procedure, unused leave of all those taking part in the saved leave scheme at the closure of the leave-year accounts will henceforth be transferred automatically to the saved leave account on that date. This simplification is in the interest of all parties concerned. This automatic transfer procedure has a number of advantages for participants in the SLS scheme. First, staff members will no longer have to take any administrative steps. Secondly, the new proced...

    Wikman, Anna; Hovén, Emma; Cernvall, Martin; Ljungman, Gustaf; Ljungman, Lisa; von Essen, Louise

    Cancer in a child is associated with a significant impact on parental employment. We assessed the proportions of parents of survivors and bereaved parents working and reporting sick leave five years after end of successful treatment (ST)/child's death (T7) compared with one year after end of ST/child's death (T6) and the association between partial post-traumatic stress disorder (PTSD) and work situation and sick leave at T7. Participants and procedure: The sample included 152 parents of survivors (77 mothers, 75 fathers) and 42 bereaved parents (22 mothers, 20 fathers) of children diagnosed with cancer in Sweden. The proportions of parents working or reporting sick leave did not differ among mothers and fathers of survivors (92% vs. 96% working, 20% vs. 18% on sick leave) or among bereaved mothers and fathers (91% vs. 90% working, 14% vs. 20% on sick leave) at T7. There was no change from T6 to T7 in the proportion of fathers working (fathers of survivors 91% vs. 96%, bereaved fathers 95% vs. 90%). Although more mothers of survivors (92% vs. 82%) and bereaved mothers (91% vs. 77%) worked at T7 than at T6, this increase was not significant. Fewer bereaved mothers reported sick leave at T7 than at T6 (14% vs. 59%, p leave at T7 than at T6 (fathers of survivors 18% vs. 8%, bereaved fathers 20% vs. 15%), this was not significant. Partial PTSD was not associated with parents' work situation or sick leave at T7. Results suggest little adverse effect on work situation and sick leave among parents of survivors and bereaved parents five years after end of ST/child's death from cancer. However, the pattern of change observed differed between parents, which could potentially indicate possible delayed consequences for fathers not captured in the present paper.

  9. Juggling work and motherhood: the impact of employment and maternity leave on breastfeeding duration: a survival analysis on Growing Up in Scotland data.

    Skafida, Valeria

    2012-02-01

    In 2005, Scotland became the first nation to make breastfeeding in public a legal right, but current breastfeeding targets and maternity leave allowance do not acknowledge the conflicting demands women face when juggling employment and motherhood. This paper explores how employment and maternity leave relate to breastfeeding duration among mothers in Scotland. The Growing Up in Scotland national longitudinal cohort study of 5,217 babies born in 2004-2005 was used. Multivariate proportional hazards regression models were specified using one cross-sectional wave of data to predict breastfeeding duration. Mothers working as employees, full-time (Hazard Ratio 1.6) or part-time (HR1.3), had a higher risk of earlier breastfeeding cessation than non-working mothers. However, self-employed mothers did not differ significantly from non-working mothers in their breastfeeding patterns. Mothers who took longer maternity leave breastfed for longer. The relationships between employment, maternity leave and breastfeeding duration were significant when controlling for known predictors of breastfeeding. Younger mothers, those with less formal education, single mothers, those of white ethnic background, and first-time mothers were more likely to stop breastfeeding sooner, as has been noted in previous research. Employment and early return to work are both factors associated with a shorter duration of breastfeeding. More flexible working conditions and more generous employment leave could help to prolong breastfeeding among working mothers. Current health and employment policy in Scotland and the UK could be better coordinated so that working mothers have the adequate support to meet the conflicting demands of employment and motherhood.

    Analyzes expansion of coal mixtures in coke ovens during coking. Methods for measuring coal expansion on both a laboratory and pilot plant scale are comparatively evaluated. The method, developed, tested and patented in Poland by the Institute for Chemical Coal Processing in Zabrze (Polish standard PN-73/G-04522), is discussed. A laboratory device developed by the Institute for measuring coal expansion is characterized. Expansion of black coal from 10 underground mines in the Ostrava-Karvina coal district and from 9 coal mines in the Upper Silesia basin in Poland is comparatively evaluated. Investigations show that coal expansion reaches a maximum for coal types with a volatile matter ranging from 20 to 25%. With increasing volatile matter in coal, its expansion decreases. Coal expansion increases with increasing swelling index. Coal expansion corresponds with coal dilatation. With increasing coal density its expansion increases. Coal mixtures should be selected in such a way that their expansion does not cause a pressure exceeding 40 MPa. 11 refs.

    The aim of this study was to perform a large-scale, national survey of physician mothers to define the personal, professional, and financial impact of maternity leave and its relationship to career satisfaction for female physicians in procedural and nonprocedural fields. Little is known about the impact of maternity leave on early career female physicians or how childbearing affects career satisfaction. A nationwide sample of physician mothers completed a 45-question anonymous, secure, online questionnaire regarding the impact of pregnancy and childbearing. One thousand five hundred forty-one respondents were attending physicians during their most recent pregnancy and 393 (25.5%) practiced in a procedural field. Overall, 609 (52.9%) reported losing over $10,000 in income during leave with no significant difference between procedural and nonprocedural fields. Maternity leave was included in only 28.9% of female physicians' most recent contracts. Proceduralists were more likely to report negative impact on referrals by maternity leave [odds ratio (OR) 1.78, 95% confidence interval (95% CI) 1.28-2.47, P = 0.001], a requirement to complete missed shifts (OR 3.04, 95% CI 2.12-4.36, P maternity leave and report high rates of career dissatisfaction, particularly those in procedural specialties. Given these findings, improved family leave policies may help improve career satisfaction for female physicians.

  15. Identity Expansion and Transcendence

    2014-05-01

    Full Text Available Emerging developments in communications and computing technology may transform the nature of human identity, in the process rendering obsolete the traditional philosophical and scientific frameworks for understanding the nature of individuals and groups.  Progress toward an evaluation of this possibility and an appropriate conceptual basis for analyzing it may be derived from two very different but ultimately connected social movements that promote this radical change. One is the governmentally supported exploration of Converging Technologies, based in the unification of nanoscience, biology, information science and cognitive science (NBIC. The other is the Transhumanist movement, which has been criticized as excessively radical yet is primarily conducted as a dignified intellectual discussion within a new school of philosophy about human enhancement.  Together, NBIC and Transhumanism suggest the immense transformative power of today’s technologies, through which individuals may explore multiple identities by means of online avatars, semi-autonomous intelligent agents, and other identity expansions.

    Nishie, Hitonaru; Nakamura, Michio

    2018-01-01

    This study reports on the first observed case of a wild chimpanzee infant being snatched immediately after delivery and consequently cannibalized by an adult male in the Mahale Mountains, Tanzania. We demonstrate "maternity leave" from long-term data from the Mahale M group and suggest that it functions as a possible counterstrategy of mother chimpanzees against the risk of infanticide soon after delivery. The subjects of this study were the M group chimpanzees at Mahale Mountains, Tanzania. The case of cannibalism was observed on December 2, 2014. We used the long-term daily attendance record of the M group chimpanzees between 1990 and 2010 to calculate the lengths of "maternity leave," a perinatal period during which a mother chimpanzee tends to hide herself and gives birth alone. We observed a very rare case of delivery in a wild chimpanzee group. A female chimpanzee gave birth in front of other members, and an adult male snatched and cannibalized the newborn infant immediately after birth. Using the long-term data, we demonstrate that the length of "maternity leave" is longer than that of nonmaternity leave among adult and adolescent female chimpanzees. We argue that this cannibalism event immediately after birth occurred due to the complete lack of "maternity leave" of the mother chimpanzee of the victim, who might lack enough experience of delivery. We suggest that "maternity leave" taken by expecting mothers may function as a possible counterstrategy against infanticide soon after delivery. © 2017 Wiley Periodicals, Inc.

    This paper evaluates the impacts of unpaid maternity leave provisions of the 1993 Family and Medical Leave Act (FMLA) on children's birth and infant health outcomes in the United States. My identification strategy uses variation in pre-FMLA maternity leave policies across states and variation in which firms are covered by FMLA provisions. Using Vital Statistics data and difference-in-difference-in-difference methodology, I find that maternity leave led to small increases in birth weight, decreases in the likelihood of a premature birth, and substantial decreases in infant mortality for children of college-educated and married mothers, who were most able to take advantage of unpaid leave. My results are robust to the inclusion of numerous controls for maternal, child, and county characteristics, state, year, and month fixed effects, and state-year interactions, as well as across several different specifications.

  19. The Chinese Tiger Mother

    Directory of Open Access Journals (Sweden)

    Jacek Hołówka

    2011-12-01

    Full Text Available In 2010 a book by Amy Chua: Battle Hymn of the Tiger Mother was published and it sparked a broad discussion among pedagogues and the open society about the factors determining educational success. Chua forms a simple and provocative thesis – the Chinese mothers are the best in the world because they don’t spoil their children, quickly introduce them into the adult culture, have high expectations of them, they are brusque and cold but they teach their children how to survive and be competitive. Chua shows this educational model as a contrast to the Western model, where the children have their own, naive and sentimental culture, their own shops and catwalks in shopping malls. The results of systematic research on education seem to prove something quite different. The educational success has to be measured using different scales, because it depends on different factors. The data published by OECD show that the level of education depends on the educational tradition of the society, level of GDP, intergenerational contacts, level of education of teachers and their social status. A strong determiner is the family, but not necessarily the mother. Even more, there is a strong correlation between the results in learning and a supporting stance of the parents, but also with their habit of spending free time with their children. The parents who take their children to the cinema, an a trip, gossip with them or take them to McDonalds, can be sure that their children will have statistically higher than the average grades. Detailed results from other sources show that success correlates the most with grades from previous class, parents’ habit of talking about things at school, higher education of the parents, being a child of a single mother, signing the child up for extracurricular classes from music and the mother working part-time. Failure correlates with being an Afro-American or Latino, checking homework by parents, free time after school without

    2012-01-01

    Parents of newborns and children with special health care needs (CSHCN) often experience conflict between employment and family responsibilities. Family leave benefits such as the federal Family and Medical Leave Act and California's Paid Family Leave Insurance program help employed parents miss work to bond with a newborn or care for an ill child. The use of these benefits, however, is rare among mothers of CSHCN and fathers in general and limited even among mothers of newborns. We explored barriers to and experiences with leave-taking among parents of newborns and CSHCN. We conducted semistructured qualitative interviews in 2008 with 10 mothers and 10 fathers of newborns and 10 mothers and 10 fathers of CSHCN in Los Angeles to explore their need for and experiences with family leave. Qualitative analytical techniques were used to identify themes in the transcripts. All parents reported difficulties in accessing and using benefits, including lack of knowledge by employers, complexity of rules and processes, and inadequacy of the benefits themselves. Parents of CSHCN also described being too overwhelmed to rapidly seek and process information in the setting of urgent and often unexpected health crises. Most parents expressed a clear desire for expert guidance and saw hospitals and clinics as potentially important providers. Even when parents are aware of family leave options, substantial barriers prevent many, especially parents of CSHCN, from learning about or applying for benefits. Clinics and hospitals might be opportune settings to reach vulnerable parents at times of need. Copyright © 2012 Academic Pediatric Association. Published by Elsevier Inc. All rights reserved.

    The majority of research identifying anxiety-promoting parenting behaviors has been conducted with mothers, leaving a gap in current knowledge about the role of fathers' parenting behaviors. In an attempt to fill this gap, this study compared anxiety-promoting parenting behaviors of anxious mothers and fathers. Parents completed self-report measures of parenting behavior and independent coders rated parenting behaviors (i.e., overcontrol, granting of autonomy, warmth, hostility, anxious behavior) of mothers (n = 34) and fathers (n = 21) during a challenging parent-child interaction task (children were ages 6-12). Results indicated that anxious fathers were observed to be more controlling than anxious mothers; while anxious mothers reported using more punishment and reinforcement of children's dependence in anxiety provoking situations compared to fathers. Findings extend our knowledge about anxious fathers, and highlight the need for additional research on the impact of fathers' parenting with respect to the development of child anxiety.

    In this second article in a two-part series, we call for the integration of strengths-based and trauma-informed care into services for teen mothers. Nurses working with teen mothers in health clinics, schools and home visiting programs can play a pivotal role in promoting their mental health. Many teen mothers have high levels of psychological distress and histories of adverse experiences that cannot be ignored, and cannot solely be addressed by referral to mental health services. Nurses must be prepared to assess for trauma and be open to listening to teen mothers' experiences. Principles of strengths-based and trauma-informed care are complementary and can be integrated in clinical services so that teen mothers' distress is addressed and their strengths and aspirations are supported. Potential screening tools, interviewing skills and basic strategies to alleviate teen mothers' distress are discussed.

    Mayer expansions promise to become a powerful tool in exact renormalization group calculations. Iterated Mayer expansions were sucessfully used in the rigorous analysis of 3-dimensional U(1) lattice gauge theory by Goepfert and the author, and it is hoped that they will also be useful in the 2-dimensional nonlinear sigma-model, and elsewhere.

    Negative thermal expansion materials are important and desirable in science and engineering applications. However, natural materials with isotropic negative thermal expansion are rare and usually unsatisfied in performance. Here, we propose a novel method to achieve two- and three-dimensional negative thermal expansion metamaterials via antichiral structures. The two-dimensional metamaterial is constructed with unit cells that combine bimaterial strips and antichiral structures, while the three-dimensional metamaterial is fabricated by a multimaterial 3D printing process. Both experimental and simulation results display isotropic negative thermal expansion property of the samples. The effective coefficient of negative thermal expansion of the proposed models is demonstrated to be dependent on the difference between the thermal expansion coefficient of the component materials, as well as on the circular node radius and the ligament length in the antichiral structures. The measured value of the linear negative thermal expansion coefficient of the three-dimensional sample is among the largest achieved in experiments to date. Our findings provide an easy and practical approach to obtaining materials with tunable negative thermal expansion on any scale.

    Full Text Available Objectives: To describe the profile of women with children aged under 4 months living in the Brazilian state capitals and in the Federal District according to their working status and to analyze the influence of maternity leave on exclusive breastfeeding (EBF among working women. Methods: This was a cross-sectional study with data extracted from the II National Maternal Breastfeeding Prevalence Survey carried out in 2008. Initially, a descriptive analysis of the profile of 12,794 women was performed, according to their working status and maternity leave and the frequency of maternity leave in the Brazilian regions and capitals. The study used a multiple model to identify the influence of maternity leave on EBF interruption, including 3766 women who declared they were working and were on maternity leave at the time of the interview. The outcome assessed in the study was the interruption of the EBF, classified by the WHO. Results: Regarding the working status of the mothers, 63.4% did not work outside of their homes and among those who worked, 69.8% were on maternity leave. The largest prevalence among workers was of women older than 35 years of age, with more than 12 years of schooling, primiparous and from the Southeast and South regions. The lack of maternity leave increased by 23% the chance of EBF interruption. Conclusion: Maternity leave contributed to increase the prevalence of EBF in the Brazilian states capitals, supporting the importance of increasing the maternity leave period from four to six months.

    In Spanish, the concepts of discapacidad (disability leave) and incapacidad (sick leave) jointly refer to the impairment of a person due to injuries, diseases or deficiencies that limit their activity in a social, personal or occupational field. However, this common link does not imply that both concepts are the same. Statistical data from INE (Instituto Nacional de Estadística: Statistic National Institute) show that Spain had in 2015 3.85 million persons with a disability (59.8% were women). Statistical data from 2015 from INSS (Instituto Nacional de Seguridad Social: Social Security National Institute) show high levels in the number of processes and in workers affected by temporary sick leave, with social costs to the social security system. Both concepts have been updated: about disability leave, Law 39/2006 adjusted terminology by avoiding the use of concepts with discriminating or pejorative connotation. Regarding sick leave, the Ley General de Seguridad Social (General Social Security Law)has been amended and came into effect in January, 2016. It is necessary to know and distinguish these aspects for a better administrative management, and a more oriented information to the affected patient.

    Full Text Available Economic globalization, trade agreements, and revolutionary changes in transportation and communication have fueled a steady increase in international migration. Foreign-born Latinas, driven by a strong desire to escape poverty and to improve life for their children, face difficult decisions as transnational mothers. These women emigrate from their countries of origin, leaving their children behind with relatives. After overcoming the hardships and dangers involved in a clandestine crossing of the U.S.-Mexico border, they continue to suffer the pain of separation from their children and to hope for eventual family reunification. This study focuses on the experiences of eight Latina transnational mothers and calls for reflection and solidarity by nurses and other health care professionals in order to influence the dynamics of social, economic, and political actions to relieve social suffering.La mondialisation, les accords commerciaux et les évolutions révolutionnaires que connaissent les secteurs des transports et des communications ont favorisé l'augmentation régulière de l’immigration internationale. Motivées par la volonté d’échapper à la pauvreté et d’offrir une vie meilleure à leurs enfants, les mères latino-américaines sont confrontées à des décisions difficiles en tant que mères transnationales. Ces femmes émigrent de leur pays d’origine, laissant leurs enfants à leur famille. Après avoir surmonté les épreuves et les dangers inhérents au passage clandestin de la frontière américano-mexicaine, elles continuent à souffrir du fait de la séparation d’avec leurs enfants et vivent dans l’espoir de se retrouver à nouveau en famille. Cette étude s’intéresse à l’expérience de huit mères latino-américaines vivant aux Etats-Unis et appelle les infirmières et autres professionnels de la santé à réfléchir et à faire preuve de solidarité afin d’influencer une dynamique d’actions sociales,

    Physician daughters of physician mothers may experience unique advantages in their career development and in combining career and family. The objective of this exploratory study, the first on mother-daughter physicians, was to compare the professional and personal characteristics of physician mothers and their physician daughters. Two hundred fourteen families with at least one mother-daughter physician pair were identified through a nationwide search; 84% of the mothers and 87% of the daughters contacted returned a 56-item questionnaire. Data were analyzed to compare professional and personal characteristics of the subset of mothers and daughters who had both responded (n = 136 pairs). Compared to their physician mothers, physician daughters were less satisfied with their career, less likely to feel in control of their work environment, more likely to report moderate or severe daily stress at work, and less likely to want their children to become physicians or to want to become physicians again if they were to relieve their lives. They were also less likely to want to change specialties. Physician daughters were more likely than their physician mothers to be 30 years or older when they had their first child, to have taken parental leave, and to have a spouse who took parental leave and less likely to experience their caregiving as a hindrance to their professional work and advancement. Despite the availability of a physician mother role model, physician daughters reported less career satisfaction and more work-related stress than their physician mothers. These findings warrant further exploration and support the need for new work-family paradigms in medicine.

    Medicaid expansion under the Affordable Care Act facilitates access to care among vulnerable populations, but 21 states have not yet expanded the program. Medicaid expansions may provide increased access to care for cancer survivors, a growing population with chronic conditions. We compare access to health care services among cancer survivors living in non-expansion states to those living in expansion states, prior to Medicaid expansion under the Affordable Care Act. We use the 2012 and 2013 Behavioral Risk Factor Surveillance System to estimate multiple logistic regression models to compare inability to see a doctor because of cost, having a personal doctor, and receiving an annual checkup in the past year between cancer survivors who lived in non-expansion states and survivors who lived in expansion states. Cancer survivors in non-expansion states had statistically significantly lower odds of having a personal doctor (adjusted odds ratio [AOR] 0.76, 95 % confidence interval [CI] 0.63-0.92, p Medicaid could potentially leave many cancer survivors with limited access to routine care. Existing disparities in access to care are likely to widen between cancer survivors in Medicaid non-expansion and expansion states.

    Full Text Available This article aims to show the results of the review of literature of relevant studies of the causal elements of intention to leave in the last five years (2009-2013. The method used to evaluate the literature was based on the seven steps for research synthesis: problem formulation, literature search, obtaining information from studies, quality assessment studies, analysis and integration of results, interpretation of evidence and presentation of results. 48 studies from 15 different countries with a sample of 35804 employees of different companies were evaluated. The findings suggest the existence of 89 different variables influencing the intention to leave of employees in an organization. The results of this study will allow researchers to better understand the variables that can be studied to verify the impact of variables such as causal elements, but also see those that have a mediating effect between them for predicting intention to leave as an element of employee turnover. This study makes three important contributions to literature of turnover. First, in this study all the parameters associated with the intention to leave were checked. Second, this study categorizes and displays in proportion relevant interests to the scientific community whom studying employee turnover across the intention to leave. And thirdly provides clues organizations to improve some of its structural and contextual features to control turnover.

    Full Text Available Objective: Giving birth and training to a child with Mental Retardation (MR can be stressful for mothers. Therefore mothers need role models and adequate preparation to effectively teach the child to function at optimum level within the environment. Nurses are in a strategic position to assume a vital role in a assisting these mothers. With observation, problem solving, and decision making. There is a lack of studies about mothers' experiences of having a child with MR. This study was preformed to investigate mother's experiences of having a child with MR and how explore and describe the experienced mothers with mental retarded child. Materials & Methods: A phenomenographic approach was used. The study was preformed at an exceptional school in Tehran. Twelve mothers were interviewed using guided interviews. Results: From 336 thematic sentences, Six categories emerged, the first having three subcategories and the second having twenty subcategories., the third having three, the fourth category having six, the fifth having two, and the sixth having two subcategories. Mother's experiences of having a child with MR, describes informants a variety of feelings, often ambivalent (acceptance and UN acceptance. In such a situation, attention to God and prayer are the most important coping strategies for positive adaptation in mothers' experiences of having a child with MR, but this perception can not effect to accept him alone. They emphasis on educational and psychological needs for better life. Conclusions: The findings of this study could be used in mothers education to promote understanding of mothers’ experiences and how best to help them. They could also be used in the general media to improve public understanding.

    We use data from the Survey of Income and Program Participation to examine the impact of leave entitlements on unpaid leave usage by men and women after the birth of a child from 1991 to 1999. The results indicate that legislation providing the right to unpaid leave has not affected men's leave usage. The results for women are mixed: in some specifications, leave entitlements are associated with increased leave taking or longer leaves, but the results depend on how we define leave coverage. Our results point to the limited impact of unpaid leave policies and the potential importance of paid-leave policies.

    The study of plasma expansion is interesting from a fundamental point of view as well as from a more applied point of view. We here give a short overview of the way properties like density, velocity and temperature behave in an expanding thermal plasma. Experimental data show that the basic phenomena of plasma expansion are to some extent similar to those of the expansion of a hot neutral gas. From the application point of view, we present first results on the use of an expanding thermal plasma in the plasma-activated catalysis of ammonia, from N 2 -H 2 mixtures

    Full Text Available ABSTRACTFailed hypospadiass cases may result in hypovascular, scarred penis with residual penile chordee and leave the patient with minimal residual skin for penile resurfacing and urethroplasty. Local tissue expansion has become a good alternative to provide skin for penis by using expanders however they require long periods of time for expansion. Besides, rapid tissue expansion was also described in different tissues. We used rapid intraoperative expansion technique by using a Foley catheter in a failed hypospadias case who had minimal residual skin secondary to infection and we concluded that rapid intraoperative tissue expansion with Foley catheter is an effective, feasible reconstructive method for easy dissection and penile resurfacing in failed hypospadiass cases.

    It is commonly believed that Alcubierre's warp drive works by contracting space in front of the warp bubble and expanding the space behind it. We show that this contraction/expansion is but a marginal consequence of the choice made by Alcubierre and explicitly construct a similar spacetime where no contraction/expansion occurs. Global and optical properties of warp-drive spacetimes are also discussed.

The apparent absence of extraterrestrials from the solar system suggests that no such civilization has arisen in the Galaxy. 1 figure

    Risk spreading in bacterial populations is generally regarded as a strategy to maximize survival. Here, we study its role during range expansion of a genetically diverse population where growth and motility are two alternative traits. We find that during the initial expansion phase fast-growing cells do have a selective advantage. By contrast, asymptotically, generalists balancing motility and reproduction are evolutionarily most successful. These findings are rationalized by a set of coupled Fisher equations complemented by stochastic simulations.

    A growing number of residents are having babies during residency training. While many businesses are working to improve maternity conditions and benefits for their employees, residency programs are often not prepared to accommodate pregnant residents. This study was conducted to examine the maternity leave experiences of women who delivered infants during their family practice residency training. Program directors from each of the 394 family practice residency programs listed in the 1993 Directory of Family Practice Residency Programs were asked to distribute surveys to female residents who gave birth during their residency training and had returned to work by the time of the study. Of 199 known eligible residents, 171 (86%) completed surveys; these women represented 127 programs located in 36 states and Puerto Rico. Only 56.8% of women were aware of their program having a written maternity leave policy. The average length of maternity leave was 8 weeks; 76% had leaves of 10 weeks or less. For many, the maternity leave was derived from more than one source, including vacation, sick time, or a mother-child elective. Nearly all (88.3%) the women breast-fed, and the mean duration of breast-feeding was more than 19 weeks. In general, participants believed that having a baby during residency was somewhat difficult. Problems frequently encountered by women after their return to work included sleep deprivation and tiredness, difficulty arranging for child care, guilt about child care, and breast-feeding. Factors that detracted most from the childbirth experience were too little sleep, problems arranging for child care, and lack of support from the partner, residency faculty, and other residents. Having a baby during residency is somewhat difficult for the average female resident. Factors that may ease this difficulty include getting adequate sleep and receiving support from one's partner, faculty, and other residents.

    2018-02-01

    Objectives The United States is one of only three countries worldwide with no national policy guaranteeing paid leave to employed women who give birth. While maternity leave has been linked to improved maternal and child outcomes in international contexts, up-to-date research evidence in the U.S. context is needed to inform current policy debates on paid family leave. Methods Using data from Listening to Mothers III, a national survey of women ages 18-45 who gave birth in 2011-2012, we conducted multivariate logistic regression to predict the likelihood of outcomes related to infant health, maternal physical and mental health, and maternal health behaviors by the use and duration of paid maternity leave. Results Use of paid and unpaid leave varied significantly by race/ethnicity and household income. Women who took paid maternity leave experienced a 47% decrease in the odds of re-hospitalizing their infants (95% CI 0.3, 1.0) and a 51% decrease in the odds of being re-hospitalized themselves (95% CI 0.3, 0.9) at 21 months postpartum, compared to women taking unpaid or no leave. They also had 1.8 times the odds of doing well with exercise (95% CI 1.1, 3.0) and stress management (95% CI 1.1, 2.8), compared to women taking only unpaid leave. Conclusions for Practice Paid maternity leave significantly predicts lower odds of maternal and infant re-hospitalization and higher odds of doing well with exercise and stress management. Policies aimed at expanding access to paid maternity and family leave may contribute toward reducing socio-demographic disparities in paid leave use and its associated health benefits.

    2006-07-01

    Young leaves are preferential targets for herbivores, and plants have developed different strategies to protect them. This study aimed to evaluate different leaf attributes of presumed relevance in protection against herbivory in four woody species (Erythroxylum argentinum, Lithrea brasiliensis, Myrciaria cuspidata, and Myrsine umbellata), growing in a dry restinga woodland in southern Brazil. Evaluation of leaf parameters was made through single-point sampling of leaves (leaf mass per area and leaf contents of nitrogen, carbon, and pigments) at three developmental stages and through time-course sampling of expanding leaves (area and strength). Leaves of M. umbellata showed the highest leaf mass per area (LMA), the largest area, and the longest expansion period. On the other extreme, Myrc. cuspidata had the smallest LMA and leaf size, and the shortest expansion period. Similarly to L. brasiliensis, it displayed red young leaves. None of the species showed delayed-greening, which might be related to the high-irradiance growth conditions. Nitrogen contents reduced with leaf maturity and reached the highest values in the young leaves of E. argentinum and Myrc. cuspidata and the lowest in M. umbellata. Each species seems to present a different set of protective attributes during leaf expansion. Myrciaria cuspidata appears to rely mostly on chemical defences to protect its soft leaves, and anthocyanins might play this role at leaf youth, while M. umbellata seems to invest more on mechanical defences, even at early stages of leaf growth, as well as on a low allocation of nitrogen to the leaves. The other species display intermediate characteristics.

  1. Watch out for the leaves!

    HSE Unit

    2013-01-01

    Now that autumn is here, dead leaves falling from the trees form a colourful carpet that is pleasing to the eye. However, the reality is less pleasant for pedestrians, since these leaves increase the risk of slipping and falling, especially when the ground is wet.   These conditions are also hazardous for two- and four-wheeled vehicles, whose grip on the ground can be severely reduced, thereby increasing the risk of them skidding out of control. Cyclists are among the most vulnerable road users when faced with these hazards. It is therefore essential to be alert to the dangers, which can be lessened by taking a few simple precautions such as moderating your speed and wearing suitable shoes. We also invite you to notify the Service Desk if you notice a road or pavement where there is a high concentration of dead leaves. The CERN Roads and Drainage Service will then ensure that the leaves are cleared in order to reduce the risk of accidents in the area.

Data from a five-month pre-expansion period (November 1, 2004, to March 1, 2005) and a five-month postexpansion period (June 1, 2005, to October 31, 2005) were included for this analysis. ED and waiting room statistics as well as diversion status were obtained. Total ED length of stay (LOS) was defined as the time from patient registration to the time leaving the ED. Admission hold LOS was defined as the time from the inpatient bed request to the time leaving the ED for admitted patients. Mean differences (95% confidence interval [CI]) in total time spent on ambulance diversion per month, diversion episodes per month, and duration per diversion episode were calculated. An accelerated failure time model was performed to test if ED expansion was associated with a reduction in ambulance diversion while adjusting for potential confounders. From pre-expansion to postexpansion, daily patient volume increased but ED occupancy decreased. There was no significant change in the time spent on ambulance diversion per month (mean difference, 10.9 hours; 95% CI = -74.0 to 95.8), ambulance diversion episodes per month (two episodes per month; 95% CI = -4.2 to 8.2), and duration of ambulance diversion per episode (0.3 hours; 95% CI = -4.0 to 3.5). Mean (+/-SD) total LOS increased from 4.6 (+/-1.9) to 5.6(+/-2.3) hours, and mean (+/-SD) admission hold LOS also increased from 3.0 (+/-0.2) to 4.1 (+/-0.2) hours. The proportion of patients who left without being seen was 3.5% and 2.7% (p = 0.06) in the pre-expansion and postexpansion periods, respectively. In the accelerated failure time model, ED expansion did not affect the time to the next ambulance diversion episode

    This paper examines whether maternity leave policies have an effect on women's mental health in older age. We link data for women aged 50 years and above from countries in the Survey of Health, Ageing and Retirement in Europe (SHARE) to data on maternity leave legislation from 1960 onwards. We use a difference-in-differences approach that exploits changes over time within countries in the duration and compensation of maternity leave benefits, linked to the year women were giving birth to their first child at age 16 to 25. We compare late-life depressive symptom scores (measured with a 12-item version of the Euro-D scale) of mothers who were in employment in the period around the birth of their first child to depression scores of mothers who were not in employment in the period surrounding the birth of a first child, and therefore did not benefit directly from maternity leave benefits. Our findings suggest that a more generous maternity leave during the birth of a first child is associated with a reduced score of 0.38 points in the Euro-D depressive symptom scale in old age.

  7. Dangerous dads? Ecological and longitudinal analyses of paternity leave and risk for child injury.

    In 1974, Sweden became the first country to permit fathers to take paid parental leave. Other countries are currently following suit issuing similar laws. While this reform supports the principles of the United Nations convention of the right for children to be with both parents and enshrines the ethos of gender equality, there has been little systematic examination of its potential impact on child health. Instead, there is uninformed debate that fathers may expose their children to greater risks of injury than mothers. In this Swedish national study, the authors therefore assess whether fathers' parental leave can be regarded as a more serious risk factor for child injuries than that of mothers. Nationwide register-based ecological and longitudinal studies of hospitalisation due to injury (and intoxication) in early childhood, involving the Swedish population in 1973-2009 (ecological design), and children born in 1988 and 1989 (n=118 278) (longitudinal design). An increase in fathers' share of parental leave over time was parallelled by a downward trend in child injury rates (age 0-4 years). At the individual level, the crude incidence of child injury (age 0-2 years) was lower during paternity as compared with maternity leave. This association was, however, explained by parental socio-demographic characteristics (multivariate HR 0.96, 95% CI 0.74 to 1.2). There is no support for the notion that paternity leave increases the risk of child injury.

    Recently it was shown that the (Ooguri–Vafa) generating function of HOMFLY polynomials is the Hurwitz partition function, i.e. that the dependence of the HOMFLY polynomials on representation R is naturally captured by symmetric group characters (cut-and-join eigenvalues). The genus expansion and expansion through Vassiliev invariants explicitly demonstrate this phenomenon. In the present paper we claim that the superpolynomials are not functions of such a type: symmetric group characters do not provide an adequate linear basis for their expansions. Deformation to superpolynomials is, however, straightforward in the multiplicative basis: the Casimir operators are β-deformed to Hamiltonians of the Calogero–Moser–Sutherland system. Applying this trick to the genus and Vassiliev expansions, we observe that the deformation is fully straightforward only for the thin knots. Beyond the family of thin knots additional algebraically independent terms appear in the Vassiliev and genus expansions. This can suggest that the superpolynomials do in fact contain more information about knots than the colored HOMFLY and Kauffman polynomials. However, even for the thin knots the beta-deformation is non-innocent: already in the simplest examples it seems inconsistent with the positivity of colored superpolynomials in non-(anti)symmetric representations, which also happens in I. Cherednik's (DAHA-based) approach to the torus knots.

    Background Maternity leave is integral to postpartum maternal and child health, providing necessary time to heal and bond following birth. However, the relationship between maternity leave and health outcomes has not been formally and comprehensively assessed to guide public health research and policy in this area. This review aims to address this gap by investigating both the correlates of maternity leave utilization in the US and the related health benefits for mother and child. Methods We searched the peer-reviewed scholarly literature using six databases for the years 1990 to early 2015 and identified 37 studies to be included in the review. We extracted key data for each of the included studies and assessed study quality using the "Weight of the Evidence" approach. Results The literature generally confirms a positive, though limited correlation between maternity leave coverage and utilization. Likewise, longer maternity leaves are associated with improved breastfeeding intentions and rates of initiation, duration and predominance as well as improved maternal mental health and early childhood outcomes. However, the literature points to important disparities in access to maternity leave that carry over into health outcomes, such as breastfeeding. Synthesis We present a conceptual framework synthesizing what is known to date related to maternity leave access and health outcomes.

    Military mothers and their children cope with unique issues when mothers are deployed. In this article, we present mothers' perspectives on how military resources affected them, their children, and their caregivers during deployment. Mothers described beneficial features of military programs such as family readiness groups and behavioral health care, processes such as unit support, and policies on length and timing of deployments. Aspects that were not supportive included inflexibility in family care plans, using personal leave time and funds for transporting children, denial of release to resolve caretaker issues, and limited time for reintegration. We offer recommendations for enhanced support to these families that the military could provide. Reprint & Copyright © 2013 Association of Military Surgeons of the U.S.

    The prevalence of breastfeeding in France is one of the lowest in Europe: 65% of infants born in France in 2010 were breastfed when leaving the maternity ward. Exclusive breastfeeding allows normal growth until at least 6 months of age, and can be prolonged until the age of 2 years or more, provided that complementary feeding is started after 6 months. Breast milk contains hormones, growth factors, cytokines, immunocompetent cells, etc., and has many biological properties. The composition of breast milk is influenced by gestational and postnatal age, as well as by the moment of the feed. Breastfeeding is associated with slightly enhanced performance on tests of cognitive development. Exclusive breastfeeding for at least 3 months is associated with a lower incidence and severity of diarrhoea, otitis media and respiratory infection. Exclusive breastfeeding for at least 4 months is associated with a lower incidence of allergic disease (asthma, atopic dermatitis) during the first 2 to 3 years of life in at-risk infants (infants with at least one first-degree relative presenting with allergy). Breastfeeding is also associated with a lower incidence of obesity during childhood and adolescence, as well as with a lower blood pressure and cholesterolemia in adulthood. However, no beneficial effect of breastfeeding on cardiovascular morbidity and mortality has been shown. Maternal infection with hepatitis B and C virus is not a contraindication to breastfeeding, as opposed to HIV infection and galactosemia. A supplementation with vitamin D and K is necessary in the breastfed infant. Very few medications contraindicate breastfeeding. Premature babies can be breastfed and/or receive mother's milk and/or bank milk, provided they receive energy, protein and mineral supplements. Return to prepregnancy weight is earlier in breastfeeding mothers during the 6 months following delivery. Breastfeeding is also associated with a decreased risk of breast and ovarian cancer in the

  17. Regulation of gas infrastructure expansion

    International Nuclear Information System (INIS)

    De Joode, J.

    2012-01-01

    The topic of this dissertation is the regulation of gas infrastructure expansion in the European Union (EU). While the gas market has been liberalised, the gas infrastructure has largely remained in the regulated domain. However, not necessarily all gas infrastructure facilities - such as gas storage facilities, LNG import terminals and certain gas transmission pipelines - need to be regulated, as there may be scope for competition. In practice, the choice of regulation of gas infrastructure expansion varies among different types of gas infrastructure facilities and across EU Member States. Based on a review of economic literature and on a series of in-depth case studies, this study explains these differences in choices of regulation from differences in policy objectives, differences in local circumstances and differences in the intrinsic characteristics of the infrastructure projects. An important conclusion is that there is potential for a larger role for competition in gas infrastructure expansion.

    The loop expansion should be divergent, possibly an asymptotic one, in the Euclidean path integral formulation. This consideration is important in applications of the symmetric and mass-independent renormalization. The [1,1] Pade approximant is calculated in a PHI 4 model. Its classical vacua may be not truely stable for nonzero coupling constant. (author)

    The interplay between cosmological expansion and local attraction in a gravitationally bound system is revisited in various regimes. First, weakly gravitating Newtonian systems are considered, followed by various exact solutions describing a relativistic central object embedded in a Friedmann universe. It is shown that the 'all or nothing' behavior recently discovered (i.e., weakly coupled systems are comoving while strongly coupled ones resist the cosmic expansion) is limited to the de Sitter background. New exact solutions are presented which describe black holes perfectly comoving with a generic Friedmann universe. The possibility of violating cosmic censorship for a black hole approaching the big rip is also discussed

    We derive finite temperature expansions for relativistic fermion systems in the presence of background magnetic fields, and with nonzero chemical potential. We use the imaginary-time formalism for the finite temperature effects, the proper-time method for the background field effects, and zeta function regularization for developing the expansions. We emphasize the essential difference between even and odd dimensions, focusing on 2+1 and 3+1 dimensions. We concentrate on the high temperature limit, but we also discuss the T=0 limit with nonzero chemical potential. Copyright copyright 1996 Academic Press, Inc

    Pins or splines allow radial expansion without slippage. Design concept for mounting rotary bearing accommodates differential thermal expansion between bearing and any structure(s) to which bearing connected. Prevents buildup of thermal stresses by allowing thermal expansion to occur freely but accommodating expansion in such way not to introduce looseness. Pin-in-slot configuration also maintains concentricity.

    Highlights: • This paper focused on the expansion planning optimization of energy systems. • Employing two form of energy: the expansion of electrical and thermal energies. • The main objective is to minimize the costs. • A new Modified Honey Bee Mating Optimization (MHBMO) algorithm is applied. - Abstract: This study focused on the expansion planning optimization of energy systems employing two forms of energy: the expansion of electrical and thermal energies simultaneously. The main objective of this investigation is confirming network adequacy by adding new equipment to the network, over a given planning horizon. The main objective of the energy expansion planning (EEP) is to minimize the real energy loss, voltage deviation and the total cost of installation equipments. Since the objectives are different and incommensurable, it is difficult to solve the problem by the conventional approaches that may optimize a single objective. So, the meta-heuristic algorithm is applied to this problem. Here, Honey Bee Mating Optimization algorithm (HBMO) as a new evolutionary optimization algorithm is utilized. In order to improve the total ability of HBMO for the global search and exploration, a new modification process is suggested such a way that the algorithm will search the total search space globally. Also, regarding the uncertainties of the new complicated energy systems, in this paper for the first time, the EEP problem is investigated in a stochastic environment by the use of probabilistic load flow technique based on Point Estimate Method (PEM). In order to evaluate the feasibility and effectiveness of the proposed algorithm, two modified test systems are used as case studies

  5. The Thermal Expansion Of Feldspars

    Science.gov (United States)

    Hovis, G. L.; Medford, A.; Conlon, M.

    2009-12-01

    Hovis and others (1) investigated the thermal expansion of natural and synthetic AlSi3 feldspars and demonstrated that the coefficient of thermal expansion (α) decreases significantly, and linearly, with increasing room-temperature volume (VRT). In all such feldspars, therefore, chemical expansion limits thermal expansion. The scope of this work now has been broadened to include plagioclase and Ba-K feldspar crystalline solutions. X-ray powder diffraction data have been collected between room temperature and 925 °C on six plagioclase specimens ranging in composition from anorthite to oligoclase. When combined with thermal expansion data for albite (2,3,4) a steep linear trend of α as a function of VRT emerges, reflecting how small changes in composition dramatically affect expansion behavior. The thermal expansion data for five synthetic Ba-K feldspars ranging in composition from 20 to 100 mole percent celsian, combined with data for pure K-feldspar (3,4), show α-VRT relationships similar in nature to the plagioclase series, but with a slope and intercept different from the latter. Taken as a group all Al2Si2 feldspars, including anorthite and celsian from the present study along with Sr- (5) and Pb-feldspar (6) from other workers, show very limited thermal expansion that, unlike AlSi3 feldspars, has little dependence on the divalent-ion (or M-) site occupant. This apparently is due to the necessitated alternation of Al and Si in the tetrahedral sites of these minerals (7), which in turn locks the tetrahedral framework and makes the M-site occupant nearly irrelevant to expansion behavior. Indeed, in feldspar series with coupled chemical substitution it is the change away from a 1:1 Al:Si ratio that gives feldspars greater freedom to expand. Overall, the relationships among α, chemical composition, and room-temperature volume provide useful predictive tools for estimating feldspar thermal expansion and give insight into the controls of expansion behavior in

    2013-01-01

    Drawing on in-depth interviews with mothers who were abused by intimate partners, we argue that mothering can be a source of empowerment that helps battered women both care for their children and survive and assert themselves. Women in the study sample described a violation of some aspect of their mothering as the reason they left their partners. However, narrative analysis exposed contradictions in participants' stories, revealing multiple factors that shaped their decisions to leave. Although motherhood was significant for the women who participated in the study, it was not their only motivation for ending their relationships with abusive partners.

    In order to offer optimal supports and services for mothers affected by intimate partner violence (IPV), an understanding of these mothers' perceptions of support needs, resources, barriers to support, and preferences for support intervention is warranted. Moreover, the growing recognition of the effects of IPV on maternal-infant relationships and of the importance of these early relationships to long-term child health outcomes suggests interventions are needed to support optimal maternal-infant relationships in these families. Thus, 64 mothers exposed to IPV when their infants were below 12 months of age participated in a retrospective qualitative study to identify mothers' support needs, resources, barriers to support, and preferences for specific support interventions to promote optimal mother-infant relationships. Participants identified both personal needs (including needs for leaving or staying with the violent partner), along with intertwined needs to care for, and help, their infants cope with the experience of violence. Mothers reported that integrated services that include information and practical support from professionals with emotional and affirmation support from peers would promote positive, nurturing mother-infant relationships and healthy child development.

    During recent decades, women have been increasingly involved in social activities. Despite the fact that mothers prefer to breastfeed, their return to work is associated with a reduction in breastfeeding frequency and duration. The present study evaluates the impact of occupational factors on continuation of breastfeeding and formula initiation in employed mothers with infants aged 6-12 months in Bandar-Abbas, Iran in 2010. This is a descriptive-analytic study on employed mothers with infants aged 6-12 months referring to healthcare centers of Bandar-Abbas in 2010. Data were collected through a questionnaire dealing with work-related factors in mothers' workplace. Out of 212 mothers who responded, 52.38% used formula to feed their children, and 27.36% had discontinued breastfeeding. The rate of formula use was significantly higher in mothers who had less than 6 months of maternity leave, those who did not have a suitable nursery or place to milk themselves and preserve the milk in their workplace, those working more than 6 hours per day, and those who could not take a breastfeeding break. It is essential to identify and support breastfeeding employed women. The employers should provide facilities such as nurseries, a suitable physical space for milking, as well as the equipment necessary for milk preservation. Also, such mothers should be granted breastfeeding breaks to feed their child or milk their breasts.

  10. Maternity Leave Length and Workplace Policies' Impact on the Sustainment of Breastfeeding: Global Perspectives.

    2017-05-01

    Breastfeeding is a global initiative of the World Health Organization and the U.S. domestic health agenda, Healthy People 2020; both recommend exclusive breastfeeding, defined as providing breast milk only via breast or bottle, through the first 6 months of an infant's life. Previous literature has shown the correlation between socioeconomic status and breastfeeding, with higher maternal education and income as predictors of sustained breastfeeding. This same population of women is more likely to be employed outside the home. PubMed and the Cochrane Database of Systematic Reviews were searched using inclusion and exclusion criteria to identify the effect of maternity leave length and workplace policies on the sustainment of breastfeeding for employed mothers. Common facilitators to sustainment of breastfeeding included longer length of maternity leave as well as adequate time and space for the pumping of breast milk once the mother returned to the workplace. Barriers included inconsistency in policy and the lack of enforcement of policies in different countries. There is a lack of consistency globally on maternity leave length and workplace policy as determinants of sustained breastfeeding for employed mothers. A consistent approach is needed to achieve the goal of exclusive breastfeeding for infants. © 2017 Wiley Periodicals, Inc.

  11. Crude oil pipeline expansion summary

    International Nuclear Information System (INIS)

    2005-02-01

    The Canadian Association of Petroleum Producers has been working with producers to address issues associated with the development of new pipeline capacity from western Canada. This document presents an assessment of the need for additional oil pipeline capacity given the changing mix of crude oil types and forecasted supply growth. It is of particular interest to crude oil producers and contributes to current available information for market participants. While detailed, the underlying analysis does not account for all the factors that may come into play when individual market participants make choices about which expansions they may support. The key focus is on the importance of timely expansion. It was emphasized that if pipeline expansions lags the crude supply growth, then the consequences would be both significant and unacceptable. Obstacles to timely expansion are also discussed. The report reviews the production and supply forecasts, the existing crude oil pipeline infrastructure, opportunities for new market development, requirements for new pipeline capacity and tolling options for pipeline development. tabs., figs., 1 appendix

  14. The bootstrap and edgeworth expansion

    CERN Document Server

    Hall, Peter

    1992-01-01

    This monograph addresses two quite different topics, in the belief that each can shed light on the other. Firstly, it lays the foundation for a particular view of the bootstrap. Secondly, it gives an account of Edgeworth expansion. Chapter 1 is about the bootstrap, witih almost no mention of Edgeworth expansion; Chapter 2 is about Edgeworth expansion, with scarcely a word about the bootstrap; and Chapters 3 and 4 bring these two themes together, using Edgeworth expansion to explore and develop the properites of the bootstrap. The book is aimed a a graduate level audience who has some exposure to the methods of theoretical statistics. However, technical details are delayed until the last chapter (entitled "Details of Mathematical Rogour"), and so a mathematically able reader without knowledge of the rigorous theory of probability will have no trouble understanding the first four-fifths of the book. The book simultaneously fills two gaps in the literature; it provides a very readable graduate level account of t...

    We investigated the effect of maternity leave length and time of first return to work on breastfeeding. Data were from the Early Childhood Longitudinal Study-Birth Cohort. Restricting our sample to singletons whose biological mothers were the respondents at the 9-month interview and worked in the 12 months before delivery (N = 6150), we classified the length of total maternity leave (weeks) as 1 to 6, 7 to 12, ≥ 13, and did not take; paid maternity leave (weeks) as 0, 1 to 6, ≥ 7, and did not take; and time of return to work postpartum (weeks) as 1 to 6, 7 to 12, ≥ 13, and not yet returned. Analyses included χ(2) tests and multiple logistic regressions. In our study population, 69.4% initiated breastfeeding with positive variation by both total and paid maternity leave length, and time of return to work. In adjusted analyses, neither total nor paid maternity leave length had any impact on breastfeeding initiation or duration. Compared with those returning to work within 1 to 6 weeks, women who had not yet returned to work had a greater odds of initiating breastfeeding (odds ratio [OR]: 1.46 [1.08-1.97]; risk ratios [RR]: 1.13 [1.03-1.22]), continuing any breastfeeding beyond 6 months (OR: 1.41 [0.87-2.27]; RR: 1.25 [0.91-1.61]), and predominant breastfeeding beyond 3 months (OR: 2.01 [1.06-3.80]; RR: 1.70 [1.05-2.53]). Women who returned to work at or after 13 weeks postpartum had higher odds of predominantly breastfeeding beyond 3 months (OR: 2.54 [1.51-4.27]; RR: 1.99 [1.38-2.69]). If new mothers delay their time of return to work, then duration of breastfeeding among US mothers may lengthen.

  2. Who is the mother? Negotiating identity in an Irish surrogacy case.

    Science.gov (United States)

    Christiansen, Karin

    2015-08-01

    An Irish surrogacy case from 2013 illustrates how negotiations of the mother's identity in a given national and legal context are drawing on novel scientific perspectives, at a time when the use of new biotechnological possibilities (such as IVF) is becoming more widespread and commonplace. The Roman dictum, 'Mater Semper Certa Est' (the mother is always certain, i.e. proven by giving birth) is contested by the finding of this Irish court, in which the judge made a declaration of parentage stating that the genetic parents of twins born using a surrogate (the mother's sister) were the parents. This article critically examines the normative background assumptions involved in this ruling. It will argue that the particular deployment of arguments from genetics and epigenetics in this court case produces a naturalization of the mother's identity that is inherently reductive. A second surrogacy case is also examined, this time regarding the rights of a woman of Irish nationality to receive paid maternity leave or paid leave similar to adoptive leave after the birth of her daughter to a surrogate mother in the US state of California. This case, which was brought to the Equality Tribunal in Ireland and decided by the Court of Justice of the European Union, is used to illustrate the possible ramifications of conflicting definitions of motherhood in the legal system. In concluding, this article argues for the development and deployment of a more complex understanding of the evolving state of motherhood within the courts, in keeping with developments in the IVF industry and the various new mother-relations it makes possible.

    Leaves show a variety of strategies for maximizing CO{sub 2} and light capture. These are more meaningfully explained if they are considered in the context of maximizing capture relative to the utilization of water, nutrients and carbohydrates reserves. There is considerable variation between crops in their efficiency of CO{sub 2} and light capture at the leaf level. Understanding of these mechanisms indicate some ways in which efficiency of resource capture could be level cannot be meaningfully considered without simultaneous understanding of implications at the canopy level. 36 refs., 5 figs., 1 tab.

    Sladek, Carol

    While the United States continues to be the only developed nation without mandated paid maternity leave, U.S. employers are blazing their own trail for new parents. This article defines parental leave, explains what's driving the increased interest in paid parental leave among employers offering it and discusses how paid parental leave can benefit employers and employees alike. Finally, the author discusses why not all employers are offering these benefits as well as considerations for employers contemplating whether paid parental leave is right for them.

  9. "Good mothering" or "good citizenship"?

    Science.gov (United States)

    Porter, Maree; Kerridge, Ian H; Jordens, Christopher F C

    2012-03-01

    Umbilical cord blood banking is one of many biomedical innovations that confront pregnant women with new choices about what they should do to secure their own and their child's best interests. Many mothers can now choose to donate their baby's umbilical cord blood (UCB) to a public cord blood bank or pay to store it in a private cord blood bank. Donation to a public bank is widely regarded as an altruistic act of civic responsibility. Paying to store UCB may be regarded as a "unique opportunity" to provide "insurance" for the child's future. This paper reports findings from a survey of Australian women that investigated the decision to either donate or store UCB. We conclude that mothers are faced with competing discourses that force them to choose between being a "good mother" and fulfilling their role as a "good citizen." We discuss this finding with reference to the concept of value pluralism.

  10. Medieval orality, mothers, and bonding.

    Science.gov (United States)

    Schwartz, Scott C

    2004-01-01

    The role of women in the Middle Ages was vilification, veneration, and exclusion. Due to the high rates of maternal and infant mortality bonding shifted from the mother-child dyad to one in which the Church, Holy Family, and king acted as pseudo-parents. In art this is suggested by the virtual absence of eye contact between the Virgin and Christ-child. Frustration of early oral needs consequent to lack of adequate mother-child bonding prompted a reactive emphasis on orality in art and legend. A decrease in infant mortality and a reciprocal improvement in mother child bonding contributed to cultural shifts in how self-realization would be accomplished during the Renaissance and in the later emergence of secular humanism.

  11. Mental and Active Preparation: Examining Variations in Women's Processes of Preparing to Leave Abusive Relationships.

    2017-02-01

    Although the process of leaving abusive relationships has received increased research attention, preparing to leave is still largely understudied. Despite an emphasis on safety planning, not all women take active steps to prepare, and the characteristics and experiences of those who do or do not actively prepare are unknown. We address this gap with a secondary data analysis of interviews with 25 abused mothers in the process of leaving. All women initially engaged in mental planning, where they had emotionally disconnected from their partners. Using constructivist grounded theory techniques, we identified two distinct groups: those whose mental planning led to active planning ( n = 11), and those who moved directly from mental planning to leaving ( n = 14) with little time or need to actively plan. The groups differed on several individual, relationship, and child factors, which may have impacted the ability or decisions to prepare. This study supports the feminist view that survivors are not helpless victims but active agents who strategize for safety. Those who engage solely in mental planning still prepare to leave, even if they do not engage in active planning. Practitioners should consider factors affecting preparations and acknowledge mental planning as a necessary effort in leaving.

  12. Parenthood motives in IVF-mothers.

    Science.gov (United States)

    Colpin, H; De Munter, A; Vandemeulebroecke, L

    1998-03-01

    This is an exploratory study to answer two questions: (1) does in-vitro fertilization (IVF)-mothers' motivation for parenthood differ from the naturally conceiving mothers' motivation for parenthood? and (2) are IVF-mothers' parenthood motives correlated with their adjustment to parenthood (in the same way as they are for naturally conceiving mothers)? The study sample consisted of 31 mothers with a 24-30 month old, single-born child conceived by homologous IVF and a comparison group of 31 mothers with a naturally conceived child. Self-rating questionnaires were used. Overall, the parenthood motivation pattern was quite similar for IVF-mothers and mothers by natural conception. However, 'identity', 'motherhood' and 'social control' were significantly more important motives for IVF-mothers than for the naturally conceiving mothers. The two former motives remained more important for IVF-mothers when findings were adjusted for the influence of the mothers' age and educational level. Possible explanations for these findings refer to the infertility history. Overall, few correlations between parenthood motives and the adjustment to parenthood were significant, both for the IVF-mothers and for the mothers by natural conception. Further (hypothesis-testing) research is needed to support these findings.

    Using a multinomial logit model with data from the Survey of Income and Program Participation, this paper tests whether the implementation of the Family and Medical Leave Act (FMLA) is associated with an increase in return to work at part-time status among first-time mothers working full-time during their pregnancy. I find a statistically significant trend of increasingly higher odds of returning to work at part-time status relative to return at full-time status, beginning in 1993 (the year in which the FMLA is implemented). Furthermore, an additional week of either state or federal leave is significantly associated with a higher odds of return at part-time status. This article provides evidence that job protection and leave legislation may help facilitate higher levels of labor force participation among women with small children, through more flexible work arrangements.

    This article attempts to solve current problems of conceptual fragmentation within the field of evolutionary economics. One of the problems, as noted by a number of observers, is that the field suffers from an assemblage of fragmented and scattered concepts (Boschma and Martin 2010). A solution...... to this problem is proposed in the form of a model of exponential expansion. The model outlines the overall structure and function of the economy as exponential expansion. The pictographic model describes four axiomatic concepts and their exponential nature. The interactive, directional, emerging and expanding...... concepts are described in detail. Taken together it provides the rudimentary aspects of an economic system within an analytical perspective. It is argued that the main dynamic processes of the evolutionary perspective can be reduced to these four concepts. The model and concepts are evaluated in the light...

In addition to major engineering, construction and renovation work related to production expansion, Saudi Aramco drilling and workover operations have been markedly expanded. Since January 1991, rig activity has doubled. As an indication of aging of Saudi production, projects include modernizing current injection water treatment facilities, installing a new seawater injection plant on the Persian Gulf, installing dewatering facilities in a number of locations and installing a pilot gas lift project. In addition, equipment orders indicate the new discoveries south of Riyadh may also need the assistance of water injection from inception of production

    Background Despite the provision of maternity leave offered to mothers, many American women fail to take leave. Methods We developed an evidence-based maternity leave educational tool for working women in California using participatory design. We tested its short-term efficacy with a randomized controlled trial of pregnant English-speakers (n=155). Results Among intervention participants exposed to the tool, 65% reported that they learned something new; 38% were motivated to seek more information; and 49% said it helped them plan their maternity leave. Among participants who delivered at ≥ 37 weeks gestation and said the tool helped them plan their leave, 89% took more than one week of prenatal leave, a significantly higher proportion than among controls who did not receive the tool (64%, p=0.049). Other findings favored trial participants, but were not statistically significant in this small sample. More intervention participants took some prenatal leave (80%) vs. controls (74%, p=0.44). Among participants who had returned to work when surveyed (n=50), mean postnatal leave uptake was on average 1 week longer for intervention participants vs. controls (13.3 vs. 12.2 weeks, p=0.54). Conclusions The first-phase evaluation of this tool shows that it successfully informed women about maternity leave options, clarified complex regulations, encouraged women to seek further information and helped plan maternity leave. Compared to controls, trial participants who used the tool to plan their leave were far more likely to take prenatal leave close to term. Future evaluation of the tool when mediated by a health provider or employer is warranted. PMID:26107519

    2010-05-01

    Full Text Available Abstract Background According to an old Swiss proverb, "a new mother lazing in childbed is a blessing to her family". Today mothers rarely enjoy restful days after birth, but enter directly into the challenge of combining baby- and self-care. They often face a combination of infant crying and personal tiredness. Yet, routine postnatal care often lacks effective strategies to alleviate these challenges which can adversely affect family health. We explored how new mothers experience and handle postnatal infant crying and their own tiredness in the context of changing hospital care practices in Switzerland. Methods Purposeful sampling was used to enroll 15 mothers of diverse parity and educational backgrounds, all of who had given birth to a full term healthy neonate. Using interpretive phenomenology, we analyzed interview and participant observation data collected during the postnatal hospital stay and at 6 and 12 weeks post birth. This paper reports on the postnatal hospital experience. Results Women's personal beliefs about beneficial childcare practices shaped how they cared for their newborn's and their own needs during the early postnatal period in the hospital. These beliefs ranged from an infant-centered approach focused on the infant's development of a basic sense of trust to an approach that balanced the infants' demands with the mother's personal needs. Getting adequate rest was particularly difficult for mothers striving to provide infant-centered care for an unsettled neonate. These mothers suffered from sleep deprivation and severe tiredness unless they were able to leave the baby with health professionals for several hours during the night. Conclusion New mothers often need permission to attend to their own needs, as well as practical support with childcare to recover from birth especially when neonates are fussy. To strengthen family health from the earliest stage, postnatal care should establish conditions which enable new mothers

    2000-01-01

    To examine medical faculty's actual and ideal parental leave arrangements with the aim of informing policy decisions. Leave lengths, effect on career, financial arrangements, and availability of temporary replacements were explored. All medical faculty (6387) in Ontario, Canada were surveyed by mail and asked about parental leave experiences since 1990. Responses of men and women were compared as were those of leave takers and the entire group. Thirty-two percent (n = 996) of the 3107 respondents were women and 68% (n = 2067) were men. Ninety-eight percent (n = 317) of new mothers had taken maternity leave, while only 21% (n = 159) of new fathers had. Both paid and unpaid leave was generally shorter than that allowed by law or identified as ideal. Parental leave had a somewhat negative effect on the careers of all faculty. Women were more worried than men about the effect of their absence on colleagues' work and more generous with ideal leave length and funding. Temporary replacement of leave takers was central to an effective leave policy. Institutional and academic culture may cause new parents to take suboptimal leave despite legislation allowing more. A change in the work environment is required for medicine to offer its teachers what it teaches--that infants benefit from nurturing, nursing, and stability early in life.

  10. Carbohydrate production, balance and translocation in leaves, shoots and fruits of Montmorency sour cherry

    Kappes, E.M.

    1986-01-01

    Carbohydrate production, export and use were studied for different organs of sour cherry (Prunus cerasus L. Montmorency). Gross carbohydrate ( 14 CO 2 ) export started between 27.2 and 77.6% of full leaf expansion. The 10th leaf developing started export later than the 7th leaf, suggesting that higher carbohydrate availability during leaf expansion delays export initiation. In support of this, gross export started earlier (44.4-52.4% full expansion) after source leaf removal, than in the control (77.6%). Translocation was primarily vertical (following orthostichies). Most leaves of fruiting shoots exported bidirectionally to the apex and fruits, only leaves closest to fruits exported exclusively to fruits during rapid cell division (Stage I) and rapid cell expansion (Stage III). Net export, determined from carbohydrate balance models started at 17 and 51% expansion for the 7th and terminal leaf, and at 26.5% of shoot elongation. Cumulative carbohydrate production of the 7th and terminal leaves during the first 9 and 11 days after emergence, exceeded carbohydrate accumulated at final size, 464.2 and 148.9 mg. A fruit carbohydrate balance was developed to determine contributions by fruit photosynthesis and fruit respiration, and to identify periods of greatest carbohydrate import. Fruit photosynthesis during development was characterized under different environmental conditions. Gross photosynthesis and chlorophyll content per fruit increased to a maximum during stage II and decreased thereafter. Gross photosynthesis approached a maximum at 40 0 C. Since dark respiration increased exponentially over the same temperature range, net photosynthesis reached a maximum at 18 0 C. Photorespiration was not detected

    This study assesses NHS doctors' experiences of paternity leave and evaluates whether practices have changed since the introduction of additional paternity leave (APL) in April 2011. An anonymised online survey designed to discover experiences and uptake of APL and ordinary paternity leave (OPL) was distributed to all members of the London Deanery Synapse® network. In total, 364 fathers responded. Their seniority ranged from foundation trainees to consultants. Following the formal introduction of OPL in 2003, the number of fathers taking any paternity leave increased (from 50% to 95.6%). The majority of respondents (76.7%) felt well supported by their employer. Since the introduction of APL, 3% of respondents took additional leave. Reasons for the low uptake of APL included the impracticalities of the law, poor awareness and perceived attitudes and implications for training. Problems with OPL included the inadequate provision of cover and difficulties in timing the leave appropriately.

    2016-01-01

    In Ghana, periodic national surveys report the practice of exclusive breastfeeding (EBF) in the general population to be over 50 %. However, little is known about EBF among professional working mothers, particularly its duration after maternity leave. Female workers are entitled to 12 weeks (84 days) of maternity leave with full pay in Ghana, and this can be extended by two additional weeks in case of a caesarean or abnormal delivery. This study assessed the prevalence of EBF, as well as factors associated with the practice among professional working mothers in one of the ten regional capitals of Ghana. The study was descriptive cross-sectional in design and employed a multi-stage sampling technique to sample 369 professional working mothers. The study was planned and implemented between January to July 2015. Study-specific structured questionnaires were used in the data collection over a period of one month. Some factors including demographic characteristics, types of facilities available at workplace to support breastfeeding, challenges to exclusive breastfeeding at the workplace and mother's knowledge base on EBF, were assessed. Exclusive breastfeeding is defined as feeding infants with only breast milk, without supplemental liquids or solids except for liquid medicine and vitamin or mineral supplements. There was a near universal awareness of exclusive breastfeeding among respondents (99 %). Even though most mothers initiated breastfeeding within an hour of delivery (91 %), the EBF rate at six months was low (10.3 %). The study identified three elements as determinants of EBF; Those who did not receive infant feeding recommendation from health workers were less likely to practice exclusive breastfeeding (Adjusted Odds Ratio [AOR] 0.45; 95 % Confidence Interval [CI] 0.27, 0.77), mothers who had shorter duration of maternity leave were less likely to practice exclusive breastfeeding (AOR 0.09; 95 % CI 0.02, 0.45), and those who had a normal delivery were

    2016-09-01

    Despite the benefits of breastfeeding, rates in the United States are low. Shorter maternity leave is associated with lower initiation and shorter durations of breastfeeding; however, little is known about how paid maternity leave may influence breastfeeding rates. We used data from the 2006-2010 U.S. National Survey of Family Growth on the most recent birth to employed women who delivered a child within the previous 5 years. Separate multivariable logistic regression models were used to describe the associations between paid leave duration (0, 1-5, 6-11, ≥ 12 weeks, maternity leave not taken) and three outcomes: 1) breastfeeding initiation, 2) 6-month duration, and 3) 6-month duration among initiators. Twenty-eight percent of prenatally employed women received no paid leave. Women who received 12 or more weeks of paid leave were more likely to initiate breastfeeding compared to women with no paid leave (87.3% vs 66.7%, adjusted odds ratio [aOR] 2.83 [95% confidence interval {CI} 1.23-6.48]). Similarly, women with 12 or more weeks of paid leave were more likely to breastfeed at 6 months, compared to women with no paid leave (24.9% vs 50.1%, aOR 2.26 [95% CI 1.20-4.26]). Among women who initiated breastfeeding, having received 12 or more weeks' paid leave increased the odds of breastfeeding for 6 or more months; however, the association was not statistically significant in the adjusted model (aOR 1.81 [95% CI 0.93-3.52]). Employed women who received 12 or more weeks of paid maternity leave were more likely to initiate breastfeeding and be breastfeeding their child at 6 months than those without paid leave.

    Progress towards gender equality involves changes in the traditional parental division - female caring and male breadwinning. One aspect is increased parental leave for fathers, which may benefit the health of mothers, children, and fathers themselves. We examined how social and health characteristics (2002) were associated with paternity leave in excess of the 'father quota' of 60 days (2003-2006) in the Stockholm Public Health Cohort. Generally, fathers with stable social position, fit lifestyles, and good health had increased chances of paternity leave uptake. Our findings may contribute to identifying target groups for parental leave strategies among fathers; they indicate also that research on gender equality and public health must carefully address the problems of confounding and health-related selection.

    2018-02-01

    Validating numerical models are one of the main aspects of engineering design. However, correlating million degrees of freedom of numerical models to the few degrees of freedom of test models is challenging. Reduction/expansion approaches have been traditionally used to match these degrees of freedom. However, the conventional reduction/expansion approaches are only limited to displacement, velocity or acceleration data. While in many cases only strain data are accessible (e.g. when a structure is monitored using strain-gages), the conventional approaches are not capable of expanding strain data. To bridge this gap, the current paper outlines a reduction/expansion technique to reduce/expand strain data. In the proposed approach, strain mode shapes of a structure are extracted using the finite element method or the digital image correlation technique. The strain mode shapes are used to generate a transformation matrix that can expand the limited set of measurement data. The proposed approach can be used to correlate experimental and analytical strain data. Furthermore, the proposed technique can be used to expand real-time operating data for structural health monitoring (SHM). In order to verify the accuracy of the approach, the proposed technique was used to expand the limited set of real-time operating data in a numerical model of a cantilever beam subjected to various types of excitations. The proposed technique was also applied to expand real-time operating data measured using a few strain gages mounted to an aluminum beam. It was shown that the proposed approach can effectively expand the strain data at limited locations to accurately predict the strain at locations where no sensors were placed.

  19. Expansion of protein domain repeats.

    Directory of Open Access Journals (Sweden)

    Asa K Björklund

    2006-08-01

    Full Text Available Many proteins, especially in eukaryotes, contain tandem repeats of several domains from the same family. These repeats have a variety of binding properties and are involved in protein-protein interactions as well as binding to other ligands such as DNA and RNA. The rapid expansion of protein domain repeats is assumed to have evolved through internal tandem duplications. However, the exact mechanisms behind these tandem duplications are not well-understood. Here, we have studied the evolution, function, protein structure, gene structure, and phylogenetic distribution of domain repeats. For this purpose we have assigned Pfam-A domain families to 24 proteomes with more sensitive domain assignments in the repeat regions. These assignments confirmed previous findings that eukaryotes, and in particular vertebrates, contain a much higher fraction of proteins with repeats compared with prokaryotes. The internal sequence similarity in each protein revealed that the domain repeats are often expanded through duplications of several domains at a time, while the duplication of one domain is less common. Many of the repeats appear to have been duplicated in the middle of the repeat region. This is in strong contrast to the evolution of other proteins that mainly works through additions of single domains at either terminus. Further, we found that some domain families show distinct duplication patterns, e.g., nebulin domains have mainly been expanded with a unit of seven domains at a time, while duplications of other domain families involve varying numbers of domains. Finally, no common mechanism for the expansion of all repeats could be detected. We found that the duplication patterns show no dependence on the size of the domains. Further, repeat expansion in some families can possibly be explained by shuffling of exons. However, exon shuffling could not have created all repeats.

    The thermal expansion of triglycine sulphate crystals doped with L-α alanine (LATGS) has been studied around the phase transition temperature (30-60 deg. C) using thermomechanical analysis TMA. With increasing the content of admixture, the transition temperature (T c ) was shifted towards higher values, while the relative changes in the dimension of the crystals (ΔL/L 0 ) of the studied directions varied both in the para- and ferroelectric phases. The transition width in the case of doped crystals was found to be broad, and this broadening increases with increasing the content of L-α alanine. (author). 12 refs, 3 figs

    Full Text Available A theoretical model is developed to describe the experimental results obtained for the isobaric thermal conductivity of rare gas solids (RGS. The isobaric thermal conductivity of RGS has been analysed within Debye approximation with regard to the effect of thermal expansion. The suggested model takes into consideration the fact that thermal conductivity is determined by U-processes while above the phonon mobility edge it is determined by "diffusive" modes migrating randomly from site to site. The mobility edge ω0 is determined from the condition that the phonon mean-free path restricted by the U-processes cannot be smaller than half of the phonon wavelength.

    This paper is a report of a study to investigate how nurses' work values, perceptions of environmental characteristics, and organizational commitment are related to their leaving intentions. Nurse leaving is a serious international problem as it contributes to the nursing shortage that threatens the welfare of society. The characteristics of nurses, the work environment and nurses' feelings towards their jobs (or organizations) have an impact on their leaving intentions. A convenience sample of 849 Registered Nurses was recruited from three public hospitals in the central-west region of Japan during 2006 and 319 completed questionnaires were returned (response rate 39%). Data were analysed using regression analysis. Nurses' work values and their perceptions of their workplace environment interacted to influence leaving intentions. When there was a match between the importance nurses placed on being able to challenge current clinical practices and the number of the actual opportunities to do so, leaving intentions were low. When there was a mismatch, intention to quit the job became stronger. In addition, organizational commitment intervened between nurses' perceptions of the match in clinical challenges and leaving intention. Nurses' leaving intentions, deserve extensive exploration of their causes. Such exploration should include attending to both nurses' needs and organizational characteristics, investigating how the match between them could affect nurses' leaving intention, and exploring factors that intervene between nurses' perceptions of the match and leaving intention.

    Kaiser, H.J.

    1976-05-01

    The Feynman path integral representation of the 2-point function for a self-interacting Bose field is investigated using an expansion ('Path Integral Expansion', PIE) of the exponential of the kinetic term of the Lagrangian. This leads to a series - illustrated by a graph scheme - involving successively a coupling of more and more points of the lattice space commonly employed in the evaluation of path integrals. The values of the individual PIE graphs depend of course on the lattice constant. Two methods - Pade approximation and Borel-type extrapolation - are proposed to extract information about the continuum limit from a finite-order PIE. A more flexible PIE is possible by expanding besides the kinetic term a suitably chosen part of the interaction term too. In particular, if the co-expanded part is a mass term the calculation becomes only slightly more complicated than in the original formulation and the appearance of the graph scheme is unchanged. A significant reduction of the number of graphs and an improvement of the convergence of the PIE can be achieved by performing certain sums over an infinity of graph elements. (author)

    Beekeeping has experienced a great expansion worldwide. Nowadays, several conventional pesticides, some organic acids, and essential oil components are the main means of chemical control used against Varroa destructor, an ectoparasite that may contribute to the colony collapse disorders. Varroa resistance against conventional pesticides has already been reported; therefore it is imperative to look for alternative control agents to be included in integrated pest management programs. A good alternative seems to be the use of plant essential oils (EOs) which, as natural products, are less toxic and leave fewer residues. Within this context, a bioprospecting program of the local flora searching for botanical pesticides to be used as varroacides was launched. A primary screening (driven by laboratory assays testing for anti-Varroa activity, and safety to bees) led us to select the EOs from Eupatorium buniifolium (Asteraceae) for follow up studies. We have chemical characterized EOs from twigs and leaves collected at different times. The three E. buniifolium EOs tested were active against Varroa in laboratory assays; however, there are differences that might be attributable to chemical differences also found. The foliage EO was selected for a preliminary field trial (on an experimental apiary with 40 hives) that demonstrated acaricidal activity when applied to the hives. Although activity was less than that for oxalic acid (the positive control), this EO was less toxic to bees than the control, encouraging further studies.

  16. Surrogate mothering: exploitation or empowerment?

    Science.gov (United States)

    Purdy, Laura M

    1989-01-01

    The morality of surrogate mothering is analyzed from a "consequentialist" framework which attempts to separate those consequences that invariably accompany a given act from those that accompany it only in particular circumstances. Critics of surrogacy argue that it transfers the burden and risk of pregnancy onto another woman, separates sex and reproduction, and separates reproduction and childrearing; none of these acts is necessarily wrong, either morally or for women's or society's basic interests. While surrogate mothering can be rendered immoral if women are coerced into the practice or become victims of subordinating or penalizing contracts, it has the potential to empower women and increase their status in society by providing a job that is less risky and more enjoyable than other jobs women are forced to take and by achieving greater social recognition for reproductive labor.

  17. Broader leaves result in better performance of indica rice under drought stress.

    Leaf growth is one of the first physiological processes affected by changes in plant water status under drought. A decrease in leaf expansion rate usually precedes any reduction in stomatal conductance or photosynthesis. Changes in leaf size and stomatal opening are potential adaptive mechanisms, which may help avoid drought by reducing transpiration rate, and can be used to improve rice genotypes in water-saving cultivation. The indica rice cultivar IR64 and four of its near-isogenic lines (NILs; BC(3)-derived lines) unique for leaf size traits, YTK 124 (long leaves), YTK 127 (broad leaves), YTK 205 (short leaves) and YTK 214 (narrow leaves), were compared in this study for changes in leaf growth and its water status. The plants were subjected to two soil water regimes, well-watered and progressive soil drying measured by the fraction of transpirable soil water (FTSW). Applied drought reduced leaf number, total leaf area, specific leaf area, plant biomass, tiller number, plant height, stomatal conductance, amount of water transpired, leaf relative water content, and leaf water potential more in IR64 and the NILs than in the respective controls; nonetheless, transpiration efficiency (TE) was slightly higher under drought than in the well-watered controls. NILs with broader leaves had higher biomass (and its individual components), less stomatal conductance, and higher TE under drought than NILs with narrow and shorter leaves. Under drought, leaf number was positively correlated with tiller number and plant height; nonetheless, root weight and total biomass, water transpired and TE, and plant height and TE were positively correlated with each other. However, a negative correlation was observed between stomatal conductance and the FTSW threshold at which normalized transpiration started to decline during soil drying. Overall, the IR64-derived lines with broader leaves performed better than NILs with narrow and short leaves under drought. Copyright 2010 Elsevier Gmb

    The introduction of new leave rules (arising from the RSL, PRP and other programs) has made the present leave management system rather complicated and difficult to manage. It has therefore been decided to replace it with a more flexible and adaptable system, which will come into force on 1st October 2000. Henceforth, days of leave will be credited monthly instead of annually. Members of the personnel will have round-the-clock direct access to more detailed, confidential information regarding their various kinds of leave. They will also receive a personal monthly statement with their pay slips. The new system does not require any amendment of the regulations, except with respect to the frequency of leave calculations (monthly instead of annual). I. Main characteristics of the new leave system1. The main feature of the new system is the creation of accounts to which leave will be credited or debited as appropriate.

    The introduction of new leave rules (arising from the RSL, PRP and other programmes) has made the present leave management system rather complicated and difficult to manage. It has therefore been decided to replace it with a more flexible and adaptable system, which will come into force on 1st October 2000. Henceforth, days of leave will be credited monthly instead of annually. Members of the personnel will have round-the-clock direct access to more detailed, confidential information regarding their various kinds of leave.They will also receive a personal monthly statement with their pay slips. The new system does not require any amendment of the regulations, except with respect to the frequency of leave calculations (monthly instead of annual). I. Main characteristics of the new leave system 1. The main feature of the new system is the creation of accounts to which leave will be credited or debited as appropriate. Depending on their circumstances, members of the personnel may have up to four individual leave...

    The ethanol and methanol extracts of Arbutus unedo leaves were screened for antioxidant activity. The antioxidant activity was determined by an improved assay based on the decolorization of the radical monocation of [2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid)] (ABTS). The ethanol and methanol extract of A. unedo leaves displayed potent antioxidant activity.

    Discussions about early hominin diets have generally excluded grass leaves as a staple food resource, despite their ubiquity in most early hominin habitats. In particular, stable carbon isotope studies have shown a prevalent C 4 component in the diets of most taxa, and grass leaves are the single most abundant C 4 resource in African savannas. Grass leaves are typically portrayed as having little nutritional value (e.g., low in protein and high in fiber) for hominins lacking specialized digestive systems. It has also been argued that they present mechanical challenges (i.e., high toughness) for hominins with bunodont dentition. Here, we compare the nutritional and mechanical properties of grass leaves with the plants growing alongside them in African savanna habitats. We also compare grass leaves to the leaves consumed by other hominoids and demonstrate that many, though by no means all, compare favorably with the nutritional and mechanical properties of known primate foods. Our data reveal that grass leaves exhibit tremendous variation and suggest that future reconstructions of hominin dietary ecology take a more nuanced approach when considering grass leaves as a potential hominin dietary resource.

    To identify the contribution of the duration of the prenatal maternity leave on term delivery. Characteristics of the prenatal maternity leave and delivery among 363 working women who had delivered a full-term infant at 1 of 4 hospitals in Montreal during 1996 were studied. The presence of an intervention or complication during delivery was observed in 68.9% of the participants. The average duration of the prenatal maternity leave was about 8 weeks (SD = 7). The adjusted risk of a difficult delivery decreased significantly with the duration of the prenatal maternity leave (OR = 0.96; 95% CI: 0.93-0.99). The duration of the maternity leave before delivery is associated with an easier term delivery for working women.

  4. Expansion of passive safety function

    1995-01-01

    Expansion of the use of passive safety functions is proposed. Two notions are presented. One is that, in the design of passive safety nuclear reactors where aversion of active components is stressed, some active components are purposely introduced, by which a system is built in such a way that it behaves in an apparently passive manner. The second notion is that, instead of using a passive safety function alone, a passive safety function is combined with some active components, relating the passivity in the safety function with enhanced controllability in normal operation. The nondormant system which the authors propose is one example of the first notion. This is a system in which a standby safety system is a portion of the normal operation system. An interpretation of the nondormant system via synergetics is made. As an example of the second notion, a PIUS density lock aided with active components is proposed and is discussed

  5. On the Need for Paid Maternity Leave in the U.S.

    2007-12-01

    Maternity leave policies in the U.S. are among the worst in the world. The 12 weeks of un-paid family leave that the U.S. grants are only surpassed by South Korea's 8 un-paid weeks as the worst treatment to mothers and newborns in the developed world. California is the only state in the U.S. where two programs exist, the State Disability Insurance (SDI) and Paid Family Leave (PFL), which cover up to $840/week for up to 12 weeks (excluding a waiting period of 7 un-paid days combined for both SDI and PFL). Even with these State contributions, the average parent of a newborn in California receives less than the 100% paid 6 weeks of Portugal and the 100% paid 12 weeks of Mexico, with all other countries providing better treatment. For mothers and fathers, time at home during the first precious months after birth or adoption is critical to getting to know their babies. It can provide long-term benefits that improve a child's brain development, social development and overall well being. Parental leave results in better prenatal and postnatal care and more intense parental bonding over a child's life. It also improves the chance that a child will be immunized; as a result, it is associated with lower death rates for infants. But lawmakers and employers are denying those benefits to most families by refusing to provide paid parental leave. For some families, the economic burden of caring for a newborn alone results in financial hardship or ruin. Fortunately, about 12% of companies in the U.S. voluntarily choose to offer some sort of paid and/or longer maternity and family care leaves. Some companies offer on-site child care as a way to facilitate breastfeeding and bonding between new mothers and their babies. Other companies allow new parents to reduce their work schedule temporarily and to telecommute from their homes, both effective ways to guarantee work productivity without requiring the sacrifice of a newborn's right to better health through breastfeeding and bonding

    The associations between mothers' part-time employment and mother well-being, parenting, and family functioning were examined using seven waves of the NICHD Study of Early Child Care and Youth Development data (N = 1,364), infancy through middle childhood. Concurrent comparisons were made between families in which mothers were employed part time and both those in which mothers were not employed and those in which mothers were employed full time. Using multivariate analysis of covariance with extensive controls, results indicated that mothers employed part time had fewer depressive symptoms during the infancy and preschool years and better self-reported health at most time points than did nonemployed mothers. Across the time span studied, mothers working part time tended to report less conflict between work and family than those working full time. During their children's preschool years, mothers employed part time exhibited more sensitive parenting than did other mothers, and at school age were more involved in school and provided more learning opportunities than mothers employed full time. Mothers employed part time reported doing a higher proportion of child care and housework than mothers employed full time. Part-time employment appears to have some benefits for mothers and families throughout the child rearing years.

    Surgical management of giant melanotic naevi remains a surgical challenge. Tissue expansion provides tissue of the same quality for the repair of defects. The aim of this study is to review tissular expansion for giant melanotic naevi. We conducted a retrospective study from 2000 to 2012. All children patients who underwent a tissular expansion for giant congenital naevi had been included. Epidemiological data, surgical procedure, complication rate and results had been analysed. Thirty-tree patients had been included; they underwent 61 procedures with 79 tissular-expansion prosthesis. Previous surgery, mostly simple excision had been performed before tissular expansion. Complete naevus excision had been performed in 63.3% of the cases. Complications occurred in 45% of the cases, however in 50% of them were minor. Iterative surgery increased the complication rate. Tissular expansion is a valuable option for giant congenital naevus. However, complication rate remained high, especially when iterative surgery is needed. Copyright © 2013 Elsevier Masson SAS.

    2016-10-01

    Children raised in single-mother families are at increased risk for psychopathology, but the mechanisms that help explain this relationship are understudied. In a community sample of diverse adolescents (N = 385, 52 % female, 48 % Caucasian) and their mothers, we hypothesized that single mothers would be more likely than cohabitating mothers to engage in negative parenting behaviors, which would predict adolescent psychopathology prospectively. Single mothers were more likely to engage in psychologically controlling behaviors, which predicted to their adolescent offspring experiencing higher rates of depressive symptoms and externalizing disorders. Girls were more susceptible to depressive symptoms via psychologically controlling parenting than boys in single-mother families. Further, single mothers were more likely to engage in rejecting parenting behaviors, which predicted to a higher prevalence of adolescent externalizing disorders. Surprisingly, rejection in single-mother families predicted to less severe anxiety symptoms in adolescents relative to two-parent families. It is likely that single mothers are not inherently inferior parents relative to cohabitating mothers; rather, their parenting practices are often compromised by a myriad of demands and stressors. Consistent with this postulate, low socioeconomic status was associated with single motherhood and negative parenting behaviors. Clinical implications and study limitations are discussed.

    The relation between mother's diet and breastmilk composition is still an open issue. Nutritional inadequacies during lactation may affect the well-being of both the mother and the infant. For this reason breast feeding women usually pay attention about their alimentary practices and about their style of life during breast-feeding period. This research was conducted to verify the adequacy of lactating mother's diet in comparison with the Italian recommended daily assumption levels of nutrients (LARN 1996) for this category. We have also compared food intake of not breast feeding mothers with the LARN, and analyzed the differences between these groups of mothers. Forty-eight healthy infants were selected, 23 bottle fed, 25 breast fed. Mothers's diet in the previous 48 hours was investigated using a structured questionnaire. The data collected were processed using software Dietosystem to obtain the daily nutrient intakes. The wetnurses's diet in comparison with the LARN 1996 resulted hypocaloric and hyperproteic, deficient in Calcium, Iron, folic acid and vitamin E. Surprisingly not breast feeding mothers's intake of nutrients is closer to LARN levels than that of breast feeding mothers. Mothers are not informed enough about their alimentation during lactating period. Pediatricians must improve their knowledge about this subject and give the mothers the information they need to achieve the recommended food requirements.

    We aimed to investigate the mother-toddler relationship in preterm toddlers. The sample consisted of 18 mothers and their preterm toddlers (group 1) and 20 mothers and their fullterm toddlers (group 2). Anxiety and depressive symptom levels, attachment pattern, and parental attitudes of mothers and social-emotional problems and developmental level of the toddlers were explored to assess possible confounding factors in the mother-toddler relationship. Two researchers rated the Parent Infant Relationship Global Assessment Scales (PIRGAS). Both the mothers in group 1 and group 2 had similar Beck Depression Inventory (BDI) and State and Trait Anxiety Inventory (STAI) scores. However, the mothers who gave birth before 32 weeks of gestation had higher trait anxiety scores than others (46±2.4 vs. 42.3±5.4, p=0.01). The groups had similar Brief Infant Toddler Social Emotional Assessment Scale (BITSEA) problem and competency scores. The parenting style of group 1 revealed that they had higher scores on the Parenting Attitude Research Instrument (PARI) subscale 5 (excessive discipline) (39.6 vs. 32.1; p=0.02). Mother-toddler interaction and attachment security were found to be similar in fullterm and moderately preterm healthy toddlers. Our findings suggest that not the preterm birth itself but the medical, developmental, and/or neurological consequences of prematurity may affect the mother-toddler interaction. To explore the independent effect of prematurity in mother-toddler dyadic relationship, longitudinally designed studies are warranted.

    Multiple expansion Stirling machines have been a topic of interest at the University of Calgary for some years. Recently a second-order computer simulation program with integral graphics package for Stirling cryocoolers with up to four stages of expansion were developed and made available to the Stirling community. Adaptation of the program to multiple expansion Stirling power systems is anticipated. This paper briefly introduces the program and presents a specimen result

    A new derivation of the Wigner Kirkwood expansion for N-fermion systems is presented, showing explicitly the connection to the WKB approximation for a single level. This allows to study separately the two ansatz required to obtain the semiclassical expansions: the asymptotic expansions in powers of ℎ and the smoothing of quantal effects. We discuss the one dimensional and three dimensional, with spherical symmetry, cases. Applications for standard potentials used in nuclear physics are described in detail

    We apply the $\\delta$-expansion perturbation scheme to the $\\lambda \\phi^{4}$ self-interacting scalar field theory in 3+1 D at finite temperature. In the $\\delta$-expansion the interaction term is written as $\\lambda (\\phi^{2})^{ 1 + \\delta}$ and $\\delta$ is considered as the perturbation parameter. We compute within this perturbative approach the renormalized mass at finite temperature at a finite order in $\\delta$. The results are compared with the usual loop-expansion at finite temperature.

    This paper presents the basic properties of chromatic derivatives and chromatic expansions and provides an appropriate motivation for introducing these notions. Chromatic derivatives are special, numerically robust linear differential operators which correspond to certain families of orthogonal polynomials. Chromatic expansions are series of the corresponding special functions, which possess the best features of both the Taylor and the Shannon expansions. This makes chromatic derivatives and ...

    An anomalously low thermal expansion observable in small particles is attributed to extending effect of the shell. It is shown that the coefficient of thermal expansion of the oxide-film-coated aluminium particles calculated using elastic constants and coefficients of thermal expansion of massive materials agres well with those measured experimentally. The linear dilatation of the shell, its stress to rupture and the values of the structural tension are estimated vs the temperature

  18. The effects of mother's physical and emotional unavailability on emotion regulation.

    Field, T

    1994-01-01

    In summary, emotion dysregulation can develop from brief or more prolonged separations from the mother as well as from the more disturbing effects of her emotional unavailability, such as occurs when she is depressed. Harmonious interaction with the mother or the primary caregiver (attunement) of the mother's physical unavailability were seen in studies of separations from the mother due to her hospitalization or to her conference trips. These separations affected the infants' play behaviors and sleep patterns. Comparisons between hospitalizations and conference trips, however, suggested that the infants' behaviors were more negatively affected by the hospitalizations than the conference trips. This probably related to these being hospitalizations for the birth of another baby--the infants no longer had the special, exclusive relationship with their mothers after the arrival of the new sibling. This finding highlights the critical importance of emotional availability. The mother had returned from the hospital, but, while she was no longer physically unavailable, she was now emotionally unavailable. Emotional unavailability was investigated in an acute form by comparing two laboratory situations, the still face paradigm and the momentary leave taking. The still face had more negative effects on the infants' interaction behaviors than the physical separation. The most extreme form of emotional unavailability, mother's depression, had the most negative effects. The disorganization or emotion dysregulation in this case is more prolonged. Changes in physiology (heart rate, vagal tone, and cortisol levels), in play behavior, affect, activity level, and sleep organization as well as other regulating functions such as eating and toileting, and even in the immune system persist for the duration of the mother's depression. My colleagues and I have suggested that these changes occur because the infant is being chronically deprived of an important external regulator of

    The purpose of the present paper is to model a physical polarimetric bidirectional reflectance distribution function (pBRDF), which can character not only the non-Lambertian but also the polarized features in order that the pBRDF can be applied to analyze the relationship between the degree of polarization and the physiological and biochemical parameters of leaves quantitatively later. Firstly, the bidirectional polarized reflectance distributions from several leaves surfaces were measured by the polarized goniometer developed by Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences. The samples of leaves include two pieces of zea mays L. leaves (young leaf and mature leaf) and a piece of E. palcherrima wild leaf. Non-Lambertian characteristics of directional reflectance from the surfaces of these three leaves are obvious. A Cook-Torrance model was modified by coupling the polarized Fresnel equations to simulate the bidirectional polarized reflectance properties of leaves surfaces. The three parameters in the modified pBRDF model, such as diffuse reflectivity, refractive index and roughness of leaf surface were inversed with genetic algorithm (GA). It was found that the pBRDF model can fit with the measured data well. In addition, these parameters in the model are related with both the physiological and biochemical properties and the polarized characteristics of leaves, therefore it is possible to build the relationships between them later.

    1987-01-01

    An expansion formula for transforming boolean algebraic expressions into disjoint form was proved. Based on this expansion formula, a method for transforming system failure function into disjoint form was devised. The fact that the expansion can be done for several elements simulatneously makes the method flexible and fast. Some examples from fault tree analysis (FTA) and network analysis were examined by the new method to show its algorithm and its merit. Besides, by means of the proved expansion formula some boolean algebraic relations can proved very easily

    The specific volume of vitamin C has been investigated by X-ray powder diffraction as a function of temperature from 110 K up to complete degradation around 440 K. Its thermal expansion is relatively small in comparison with other organic compounds with an expansivity α v of 1.2(3) × 10-4 K-1. The structure consists of strongly bound molecules in the ac plane through a dense network of hydrogen bonds. The thermal expansion is anisotropic. Along the b axis, the expansion has most leeway and is about 10 times larger than in the other directions.

    We perform one dimensional numerical simulations with a Lagrangian hydrodynamics code of the adiabatic expansion of a supernova into the surrounding medium. The early expansion follows Chevalier's analytic self-similar solution until the reverse shock reaches the ejecta core. We follow the expansion as it evolves towards the adiabatic blast wave phase. Some memory of the earlier phases of expansion is retained in the interior even when the outer regions expand as a blast wave. We find the results are sensitive to the initial configuration of the ejecta and to the placement of gridpoints. 6 refs., 2 figs

    2004-01-01

    The US Newborns' and Mothers' Health Protection Act of 1996 ('The Two-Day Law') mandates insurance coverage for women who have just given birth to remain in hospital for two days post-partum. However, many women are being discharged from hospital after 24 hours. To assess why early discharge is still occurring, a study of 406 new mothers was conducted at an urban metropolitan hospital in the USA. The women were aware of the new law (95%) but decision making was often relinquished to hospital authorities. Patients who stayed longer tended to be more assertive in decision making, and used the Two-Day Law as leverage in discussions about going home. The study concluded that the nurses were authoritative and often influential agents in the decision-making process, and that patients were likely to interpret specific interactions with hospital staff as a signal to leave.

    The offspring of an epileptic mother is an issue-currently getting attention because of its several implications. A complex interaction between epilepsy during pregnancy and its adverse impact on foetus, labor, neonate, congenital malformation, psychosocial and medico-social concern and treatment challenges of such cases is increasingly being realised. Some of the significant observations has been reviewed extensively in this article. Maternal epilepsy is likely to adversely affect the off-spring at its various stages of development amounting to increased morbidity and mortality. Increased seizure frequency during pregnancy with resultant increased risk is well documented but its mechanism is poorly understood. Low apgar score, increased still birth rates (1.3 to 14%) in offspring of epileptic mother (OEM) is reported. So also, the neonatal and perinatal deaths are twice more common in OEMS than normal control. Small for dates, and prematurity in OEM is reported to be 7 to 10% and 4-11% respectively. Adverse impact on labor and delivery like preclampsia, abruptio placentae, polyhydramnios, assisted delivery, cesarean section and IUGR poses particular challenges to the obstetrician. Pediatrician's alertness is needed to anticipate and deal with the bleeding manifestation due to deficiency of Vit-K dependent clotting factors and various anticonvulsant drug (AED) withdrawal symptoms. Significant risk of developing congenital malformation is the result of epilepsy perse and the AED used during pregnancy. AED exposure leads to other distinct clinical syndromes, the orofacial clefts and cardiac anomalies being the commonest manifestation. Epilepsy in mother but not in father has significant adverse impact. Management strategies in the context of available observation has been discussed.

    Mainguy, S; Crouse, B J

    1998-09-01

    To help recruit and retain physicians, especially women, rural family practice groups need to establish policies regarding maternity and other family leaves. Also important are policies regarding paternity leave, adoptive leave, and leave to care for elderly parents. We surveyed members of the American Academy of Family Physicians in rural practice in 1995 to assess the prevalence of leave policies, the degree to which physicians are taking family leave, and the characteristics of ideal policies. Currently, both men and women physicians are taking family leaves of absence, which indicates a need for leave policies. Furthermore, a lack of family leave policies may deter women from entering rural practice.

  6. From alienation to familiarity: experiences of mothers and fathers of preterm infants.

    The birth of a preterm infant has a long-term impact on both parents. Mothers report more stress and poor adjustment compared with fathers. Influencing factors, such as family situation and health status of the child, can support or weaken the coping ability of the parents. Studies on experiences of fathers are sparse. The aim of this research was to study how mothers and fathers of preterm infants describe their experiences of parenthood during the infant's first 18 months of life. Seven consecutively selected sets of parents of preterm infants born at mothers and fathers described their parental roles involved concern for the child, insecurity, adjustment and relationship with the child. Regarding differences, mothers experienced having more responsibility and control of the care and a need to be confirmed as a mother, while fathers described confidence in leaving the care to the staff and wanted to find a balance between work and family life. Important turning points in parenthood experiences often occurred when the infant could be removed from the incubator, discharged from the ward, and when the infant looked normal compared to full-term infants. The structure of the phenomenon of parenthood was formed by the integration of the syntheses of alienation, responsibility, confidence and familiarity. The structure seems to be based on the parents' expectations of the parental role, the infant's health condition and the health care environment. These interacting factors are influenced by cultural beliefs.

    Separation from the family, a key developmental task, has received scant attention from developmentalists. In this study, college students' dissimilarity ratings and ratings on 22 bipolar adjective scales were obtained for a set of 20 definitions of home-leaving. Results of a cluster analysis revealed that conceptualizations of the definitions are organized in terms of eight clusters. Ratings on the 22 adjective scales provided an empirical means for interpreting the typological structure of the home-leaving definitions. Convergence the results of this inductive study of home-leaving and elements of ego development theory was noted.

    Laser induced fluorescence (LIF) is successfully used as a technique for remote detection of spectral characteristics of some plants. A pulsed nitrogen laser at 337.1 nm is used to excite cotton, corn and rice leaves. The fluorescence spectrum is detected in the range from 340 nm to 820 nm. It is found that, these plant leaves have common fluorescence maxima at 440 nm, 685 nm and 740 nm. plant leaves are also found to be identifiable by the ratio of the fluorescence intensity at 440 nm to that at 685 nm. The present technique can be further used as a means of assessing, remotely, plant stresses. 5 fig

    The American Academy of Pediatrics recommends 6 months of exclusive breastfeeding, however, only 16% of US infants meet this recommendation. Shorter exclusive/predominant breastfeeding durations have been observed from women who return to work early and/or full-time. We assessed the relationship between prenatal plans for maternity leave duration and return to full-time/part-time status and plans for exclusive breastfeeding. This study included 2348 prenatally employed women from the Infant Feeding Practices Study II (2005-2007) who planned to return to work in the first year postpartum. Bivariate analysis and logistic regression were used to describe the association of maternity leave duration and return status with plans for infant feeding. Overall, 59.5% of mothers planned to exclusively breastfeed in the first few weeks. Mothers planning to return to work within 6 weeks had 0.60 times the odds (95% confidence interval [CI], 0.46-0.77) and mothers planning to return between 7 and 12 weeks had 0.72 times the odds (95% CI, 0.56-0.92) of planning to exclusively breastfeed compared with mothers who were planning to return after 12 weeks. Prenatal plans to return full-time (≥ 30 hours/week vs part-time) were also associated with lower odds of planning to exclusively breastfeed (adjusted odds ratio = 0.61; 95% CI, 0.51-0.77). Mothers planning to return to work before 12 weeks and/or full-time were less likely to plan to exclusively breastfeed. Longer maternity leave and/or part-time return schedules may increase the proportion of mothers who plan to exclusively breastfeed. © International Lactation Consultant Association 2014.

  13. Hubble expansion in static spacetime

    Rossler, Otto E.; Froehlich, Dieter; Movassagh, Ramis; Moore, Anthony

    2007-01-01

    A recently proposed mechanism for light-path expansion in a static spacetime is based on the moving-lenses paradigm. Since the latter is valid independently of whether space expands or not, a static universe can be used to better see the implications. The moving-lenses paradigm is related to the paradigm of dynamical friction. If this is correct, a Hubble-like law is implicit. It is described quantitatively. A bent in the Hubble-like line is predictably implied. The main underlying assumption is Price's Principle (PI 3 ). If the theory is sound, the greatest remaining problem in cosmology becomes the origin of hydrogen. Since Blandford's jet production mechanism for quasars is too weak, a generalized Hawking radiation hidden in the walls of cosmic voids is invoked. A second prediction is empirical: slow pattern changes in the cosmic microwave background. A third is ultra-high redshifts for Giacconi quasars. Bruno's eternal universe in the spirit of Augustine becomes a bit less outlandish

  14. Primordial vorticity and gradient expansion

    CERN Document Server

    Giovannini, Massimo

    2012-01-01

    The evolution equations of the vorticities of the electrons, ions and photons in a pre-decoupling plasma are derived, in a fully inhomogeneous geometry, by combining the general relativistic gradient expansion and the drift approximation within the Adler-Misner-Deser decomposition. The vorticity transfer between the different species is discussed in this novel framework and a set of general conservation laws, connecting the vorticities of the three-component plasma with the magnetic field intensity, is derived. After demonstrating that a source of large-scale vorticity resides in the spatial gradients of the geometry and of the electromagnetic sources, the total vorticity is estimated to lowest order in the spatial gradients and by enforcing the validity of the momentum constraint. By acknowledging the current bounds on the tensor to scalar ratio in the (minimal) tensor extension of the $\\Lambda$CDM paradigm the maximal comoving magnetic field induced by the total vorticity turns out to be, at most, of the or...

  15. From maternity to parental leave policies: women's health, employment, and child and family well-being.

    Science.gov (United States)

    Kamerman, S B

    2000-01-01

    Pregnancy and maternity are increasingly viewed as social as well as individual risks that require health protection, employment protection and security, and protection against temporary loss of income. Begun more than a century ago in Germany, paid and job-protected maternity leaves from work were established in most countries initially out of concern for maternal and child physical health. Beginning in the 1960s, these policies have expanded to cover paternity and parental leaves following childbirth and adoption as well. Moreover, they have increasingly emerged as central to the emotional and psychological well-being of children as well as to the employment and economic security of their mothers and fathers. They are modest social policies, but are clearly an essential part of any country's child and family policy. No industrialized country today can be without such provision, and the United States is a distinct laggard in these developments.

    Based on the general formula for finding qualified mother wavelets [Opt. Lett. 31 (2006) 407] we make wavelet transforms computed with the newly found mother wavelets (characteristic of the power 2n) for some optical Gaussian pulses, which exhibit the ability to measure frequency of the pulse more precisely and clearly. We also work with complex mother wavelets composed of new real mother wavelets, which offer the ability of obtaining phase information of the pulse as well as amplitude information. The analogy between the behavior of Hermite-Gauss beams and that of new wavelet transforms is noticed. (general)

    We introduce childcare sharing in a collective model of household behavior to investigate which factors make spouses increase or decrease their share of parental leave. The concern about future consumption motivates parents to invest in their human capital and to limit their leave duration. Using relative income and the age difference between spouses as distribution factors, we cannot reject Pareto efficiency in childcare sharing. Higher relative incomes and larger age differences shift the c...

    2018-03-01

    Manufacturing particleboard (PB) made of leaves was carried out to make non-structural building components, such as insulation, partition, wall, and sheathing. Raw materials used dry leaves originated from plantation (palm oil leaves) and forest plantation (magahony leaves). The adhesive used was interior type thermosetting commercial resins, namely 10% urea-formaldehyde (UF) based on oven dry leaves. Hardener used for UF resin was 1% and 3% ammonium chloride (NH4Cl) 20% (w/w), respectively. Technically, the target density of PB was 0.8 g/cm3 with the dimension’s size of (250 x 250 x 10) mm3. The pressure, temperature, and time of pressing of the hot press were 25 kgf/cm2, 120C, and 10 minutes, respectively. After conditioning for one week, the PB then was evaluated their physical and mechanical properties according to Japanese Industrial Standard (JIS) A 5908 (2003). Results of this work showed: 1) Both types of PB (palm oil and mahagony leaves) were feasible to be produced for non-structural applications; 2) Addition of hardener enhanced the physical and mechanical properties of PB; 3) It was recommended to enhance the performance of the PB by manipulation of the raw materials and the design.

    2014-01-01

    The effect of office type on sickness absence among office employees was studied prospectively in 1852 employees working in (1) cell-offices; (2) shared-room offices; (3) small, (4) medium-sized and (5) large open-plan offices; (6) flex-offices and (7) combi-offices. Sick leaves were self-reported two years later as number of (a) short and (b) long (medically certified) sick leave spells as well as (c) total number of sick leave days. Multivariate logistic regression analysis was used, with adjustment for background factors. A significant excess risk for sickness absence was found only in terms of short sick leave spells in the three open-plan offices. In the gender separate analysis, this remained for women, whereas men had a significantly increased risk in flex-offices. For long sick leave spells, a significantly higher risk was found among women in large open-plan offices and for total number of sick days among men in flex-offices. A prospective study of the office environment's effect on employees is motivated by the high rates of sick leaves in the workforce. The results indicate differences between office types, depending on the number of people sharing workspace and the opportunity to exert personal control as influenced by the features that define the office types.

  15. Postnatal Mother-to-Infant Attachment in Subclinically Depressed Mothers: Dyads at Risk?

    Science.gov (United States)

    Behrendt, Hannah F; Konrad, Kerstin; Goecke, Tamme W; Fakhrabadi, Roya; Herpertz-Dahlmann, Beate; Firk, Christine

    Dyadic interactions between children and depressed mothers have been characterized as less synchronous and with lower maternal sensitivity, fostering an inharmonious, insecure attachment relationship between mother and child. Thus, these children may experience enhanced early life stress and are at higher risk of disturbed socioemotional development. Recently, this association has also been found in women with mild depressive symptoms. However, potential confounding effects of mother's history of own rearing experiences or infant temperament on the link between depressive symptoms and postnatal mother-to-infant attachment have not yet been investigated. Differences in mother-to-infant attachment (e.g. quality of attachment, absence of hostility, and pleasure in interaction) between mothers with and without symptoms of depression 6-8 months postpartum were analyzed in a low-risk community sample (n = 38, 19 per group). Depressive symptomatology was measured with the Beck Depression Inventory (BDI-II) and the Edinburgh Postnatal Depression Scale (EPDS). Depressed mothers indicated mild-to-moderate depressive symptomatology (mean BDI-II 11.26 ± 3.86) but did not fulfill criteria for a major depressive episode and, thus, were referred to as 'subclinically' depressed. Potential confounders, namely maternal history of own rearing experiences and infant temperament, were explored by multivariate AN(C)OVA. Primiparous mothers with subclinical depression differed significantly from healthy control mothers, i.e. showed poorer mother-to-infant attachment and higher infant-related hostility 6-8 months postpartum. As expected, infant temperament and mother's history of own rearing experiences were both associated with mother-to-infant attachment but did not explain the negative effects of subclinical depression on the mother-infant relationship. Given the high prevalence of maternal depression, the current findings give reason for increased concern for the developing mother

    Full Text Available The Abelian semigroup expansion is a powerful and simple method to derive new Lie algebras from a given one. Recently it was shown that the S-expansion of so(3,2 leads us to the Maxwell algebra M. In this paper we extend this result to superalgebras, by proving that different choices of abelian semigroups S lead to interesting D=4 Maxwell Superalgebras. In particular, the minimal Maxwell superalgebra sM and the N-extended Maxwell superalgebra sM(N recently found by the Maurer–Cartan expansion procedure, are derived alternatively as an S-expansion of osp(4|N. Moreover, we show that new minimal Maxwell superalgebras type sMm+2 and their N-extended generalization can be obtained using the S-expansion procedure.

    The paper discusses the mode of action of different systems of expansion joints. Special regard is given to the problems of expansion of pipelines of high rated diameter as employed in today's large power plant turbines. Due to the limited space available, the important role of the spring rate of the bellows for the reaction forces and moments acting on the connection points is pointed out. Apart from this details are given on the fabrication and materials selection of expansion joint bellows, and problems are discussed which arise in connection with the mechanical or hydraulic deformation of bellows with one or more walls. The non-destructive methods now in use for the testing of expansion pipe joints are mentioned along with experiments to test their behaviour under changing loads. The paper concludes on some remarks concerning proper transport, storage and installation of expansion pipe joints. (orig./AK) [de

  19. Child Health in Elementary School Following California’s Paid Family Leave Program.

    Science.gov (United States)

    Lichtman-Sadot, Shirlee; Bell, Niryvia Pillay

    We evaluate changes in elementary school children health outcomes following the introduction of California’s Paid Family Leave (PFL) program, which provided parents with paid time off following the birth of a child. Our health outcomes--overweight, ADHD, and hearing-related problems--are characterized by diagnosis rates that only pick up during early elementary school. Moreover, our health outcomes have been found to be negatively linked with many potential implications of extended maternity leave--increased breastfeeding, prompt medical checkups at infancy, reduced prenatal stress, and reduced non-parental care during infancy. Using the Early Childhood Longitudinal Studies (ECLS) within a difference-in-differences framework, our results suggest improvements in health outcomes among California elementary school children following PFL’s introduction. Furthermore, the improvements are driven by children from less advantaged backgrounds, which is consistent with the notion that California’s PFL had the greatest effect on leave-taking duration after childbirth mostly for less advantaged mothers who previously could not afford to take unpaid leave.

    The aim of this study was to explore the mothering experience and practice among reservation-based adult American Indian women who had been adolescent mothers. Adolescent American Indian women are at an elevated risk for teen pregnancy and poor maternal/child outcomes. Identifying mothering practices among this population may help guide intervention development that will improve health outcomes. A collaborative orientation to community-based participatory research approach. Employing interpretive phenomenology, 30 adult American Indian women who resided on a Northwestern reservation were recruited. In-depth, face-to-face and telephone interviews were conducted between 2007-2008. Women shared their mothering experience and practice, which encompassed a lifespan perspective grounded in their American Indian cultural tradition. Four themes were identified as follows: mother hen, interrupted mothering and second chances, breaking cycles and mothering a community. Mothering originated in childhood, extended across their lifespan and moved beyond mothering their biological offspring. These findings challenge the Western construct of mothering and charge nurses to seek culturally sensitive interventions that reinforce positive mothering practices and identify when additional mothering support is needed across a woman's lifespan. © 2013 John Wiley & Sons Ltd.

    South, Scott J; Lei, Lei

    2015-12-01

    The percentage of young American adults residing in their parents' home has increased markedly over recent years, but we know little about how sociodemographic, life-course, and parental characteristics facilitate or impede leaving or returning home. We use longitudinal data from the Panel Study of Income Dynamics' Transition into Adulthood survey to examine the determinants of leaving and returning home among youth who turned age 18 between 2005 and 2011. Findings from event history models show that while leaving and returning home is to some extent a function of normative life-course transitions, characteristics of the parental home (e.g., presence of co-resident siblings, mother's educational attainment) and the degree of family connectivity (e.g., emotional closeness to mother, instrumental help from family) also play important roles. Experiencing physical, including sexual, victimization drives young adults both out of, and back into, the parental home. Having parents in poor physical health encourages young adults to move back home. Overall, the results suggest that a comprehensive explanation for both home-leaving and home-returning will need to look beyond life-course transitions and standard economic accounts to encompass a broader array of push and pull factors, particularly those that bond young adults with their parents.

  6. Residual stresses associated with the hydraulic expansion of steam generator tubing into tubesheets

    International Nuclear Information System (INIS)

    Middlebrooks, W.B.; Harrod, D.L.; Gold, R.E.

    1991-01-01

    Westinghouse has used three different processes for the full depth expansion of tubes into the tube sheets of recirculating nuclear steam generators: mechanical rolling, explosive expansion and hydraulic expansion. Each process aims at expanding tubes tightly to tube sheets, leaving the smallest possible secondary side crevice depth, and minimizing the residual stress in the expanded tubes, all for the purpose of mitigating the effect of corrosion phenomena. The hydraulic expansion process was qualified and has been implemented since 1978, and more than 1.1 million tube ends have been hydraulically expanded into production units. In this paper, the results of the recent analytical studies related to the residual stress in the expanded tubes are summarized. The method of hydraulic expansion is explained, and some important parameters are given. Finite element method, theoretical incremental analysis, tube sheet yielding and residual stress, contact pressure, sensitivity analysis and temperature effect in the central region of tube sheets, and the residual stress in the transition zone are described.

  7. The effects of Earned Income Tax Credit payment expansion on maternal smoking.

    2013-11-01

    The Earned Income Tax Credit is the largest antipoverty program in the USA. In 1993, the Earned Income Tax Credit benefit levels were changed significantly based on the number of children in the family such that families with two or more children experienced an exogenous expansion in their incomes. Using data from the National Longitudinal Survey of Youth 1979 cohort, we use a triple-difference plus fixed effects framework to examine the effect of this change on the probability of smoking among low-educated mothers. We find that the probability of smoking for White low-educated mothers of two or more children significantly decreased relative to those with only one child, and this result is robust to various specification tests. This result provides new evidence on the protective effect of income on health through changes in a health-related behavior and therefore has important policy implications.

    2016-01-01

    The World Health Organization (WHO) recommends that mothers exclusively breastfeed for the first 6 months of an infant's life. In Ireland, currently paid maternity leave is 26 weeks and the expectant mother is required by law to finish work 2 weeks before her expected delivery date. Mothers wishing to exclusively breastfeed for 6 months or longer find themselves having to take holiday leave or unpaid leave from work in order to meet the WHO's guidelines. The aim of this study is to explore women's experiences of breastfeeding after their return to work in Ireland. This study was carried out utilizing a qualitative design. Initially 25 women who returned to the workforce while continuing to breastfeed were contacted, 16 women returned consent forms and were subsequently contacted to take part in an interview. Interviews were recorded and transcribed verbatim and thematic analysis was employed to establish recurring patterns and themes throughout the interviews. Women noted that cultural attitudes in Ireland coupled with inadequate or inconsistent advice from health professionals posed the biggest challenge they had to overcome in order to achieve to 6 months exclusive breastfeeding. The findings of this study illustrate that mothers with the desire to continue to breastfeed after their return to work did so with some difficulty. Many did not disclose to their employers that they were breastfeeding and did not make enquiries about being facilitated to continue to breastfeed after their return to the workplace. The perceived lack of support from their employers as well as embarrassment about their breastfeeding status meant many women concealed that they were breastfeeding after their return to the workplace. While it has been suggested that WHO guidelines for exclusive breastfeeding for 6 months may be unattainable for many women due to work commitments, a different problem exists in Ireland. Mothers struggle to overcome cultural and societal obstacles coupled

  18. δ expansion applied to quantum electrodynamics

    International Nuclear Information System (INIS)

    Bender, C.M.; Boettcher, S.; Milton, K.A.

    1992-01-01

    A recently proposed technique known as the δ expansion provides a nonperturbative treatment of a quantum field theory. The δ-expansion approach can be applied to electrodynamics in such a way that local gauge invariance is preserved. In this paper it is shown that for electrodynamic processes involving only external photon lines and no external electron lines the δ expansion is equivalent to a fermion loop expansion. That is, the coefficient of δ n in the δ expansion is precisely the sum of all n-electron-loop Feynman diagrams in a conventional weak-coupling approximation. This equivalence does not extend to processes having external electron lines. When external electron lines are present, the δ expansion is truly nonperturbative and does not have a simple interpretation as a resummation of conventional Feynman diagrams. To illustrate the nonperturbative character of the δ expansion we perform a speculative calculation of the fermion condensate in the massive Schwinger model in the limit of large coupling constant

  19. Stigma in mothers of deaf children.

    A deaf child creates a feeling of stigma in many hearing parents. Stigma in mothers can have a negative impact on a child's treatment and rehabilitation process. Therefore, this study was conducted to evaluate the extent of stigma in mothers with deaf children. This descriptive, cross-sectional study was conducted in 2013 among 90 mothers with deaf children. The data-collection instrument included the stigma scale in the mothers of children with disabilities. The reliability and validity of the instrument were confirmed through content validity and Cronbach's alpha coefficient (α=86%), respectively. Data were analyzed using SPSS-15 software. Results showed that most mothers suffer from stigma due to having a deaf child. The mean stigma score was 96.48 ±27.72. In total, 24.4% of mothers reported that they had received strange and mocking looks; 72.2% regarded child deafness as a sign of divine retribution; and 33.3% felt ashamed of their child's deafness. There was an inverse relationship between the mother's level of education and mean stigma scores (P<0.033). The stigma score was higher in mothers who were living independently of their relatives (P<0.029). The mean stigma score in mothers of children with a cochlear implant was lower than that of mothers of children with earphones (86.70 vs. 99.64), and this difference tended towards significance (P=0.057). This study showed that half of all mothers with deaf children were scorned and felt ashamed of having a deaf child in the family because of the stigma. The majority of mothers with deaf children felt stigmatized, and only their education and residency status affected this issue. The mothers of cochlear-implanted children perceived less stigma. Due to the various social and psychological problems caused by hearing impairment, it is necessary to consider the emotional health and psychological state of the mothers in addition to rehabilitation programs and standard services for the children themselves.

    2004-01-01

    Since 1958, phototherapy has been used as a method to cure jaundice, which is still an important disease in newborn children. Supported by a phenomenological and qualitative approach, this study aims to investigate the mothers' perception of the phototherapy treatment their children are submitted to. Research subjects were ten mothers of newborns under phototherapy treatment at the Neonatological Hospitalization Unit of a public maternity in Fortaleza-CE, Brazil. Data were collected between May and July 2002. We used group meetings with the mothers as suggested by Carl Rogers. Discourse was organized into categories according to Bardin, which revealed themes that were analyzed in view of Paterson's and Zderad's humanistic nursing theory, as follows: mothers' knowledge on phototherapy and concerns about the treatment. We concluded that the analyzed mothers' major concern is related to the babies' vision.

    2007-04-01

    This qualitative study aimed to explore mothers' experiences of the support they received from community health professionals. Every third mother was selected from an NHS Trust's database of women whose health visitors had used the Solihull Approach. Forty-two women were sent information packs and consent forms. Nine mothers who returned consent forms were interviewed. The interview transcripts were analysed using interpretative phenomenological analysis. The results expand on previous research and contribute additional ideas to the existing evidence base. The findings explore the concepts of trust, expertise and understanding within the working partnership. In addition, the results address mothers' need for reliability, and a preference for professionals who understood women's beliefs about what it means to be a 'good mother'. The results and recommendations are pertinent to those community health professionals who work in the area of early childhood intervention, including practitioners who use the Solihull Approach.

    Incarceration of a mother disrupts the mother-child relationship and the child's emotional development. The researchers evaluated a 15-week parenting program in a women's prison that was designed to enhance mother-child interactions during imprisonment. Pre- and postmeasures for the 104 women were Hudson's (1982) Index of Self-Esteem, Bavolek's (1984) Adult-Adolescent Parenting Inventory, and semistructured questionnaires. Self-esteem and attitudes about expectations of children, corporal punishment, and family roles improved significantly. Empathy and mother-child interactions through visits and letters improved. Participants identified the most helpful components of the program. Those who had been physically, sexually, and emotionally abused and those who had used drugs and alcohol had positive results. Findings support the value of parent education for self-development of incarcerated mothers and for the welfare of their children.

    1979-01-01

    Different discrete expansions of the continuum wave functions are considered: pole expansion (according to the Mittag-Lefler theorem), Weinberg states. The general property of these groups of states is their completeness in the finite region of space. They satisfy the Schroedinger type equations and are matched with free solutions of the Schroedinger equation at the boundary. Convergence of expansions for the S matrix, the Green functions and the continuous-spectrum wave functions is studied. A new group of states possessing the best convergence is introduced

  8. Semiclassical expansions on and near caustics

    Meetz, K.

    1984-09-01

    We show that the standard WKB expansion can be generalized so that it reproduces the behavior of the wave function on and near a caustic in two-dimensional space time. The expansion is related to the unfolding polynomials of the elementary catastrophes occurring in two dimensions: the fold and the cusp catastrophe. The method determines control parameters and transport coefficients in a self-consistent way from differential equations and does not refer to the asymptotic expansion of Feynman path integrals. The lowest order equations are solved explicitly in terms of the multivalued classical action. The result is a generalized semiclassical approximation on and beyond a caustic. (orig.)

  9. Cosmic growth history and expansion history

    Linder, Eric V.

    2005-01-01

    The cosmic expansion history tests the dynamics of the global evolution of the universe and its energy density contents, while the cosmic growth history tests the evolution of the inhomogeneous part of the energy density. Precision comparison of the two histories can distinguish the nature of the physics responsible for the accelerating cosmic expansion: an additional smooth component--dark energy--or a modification of the gravitational field equations. With the aid of a new fitting formula for linear perturbation growth accurate to 0.05%-0.2%, we separate out the growth dependence on the expansion history and introduce a new growth index parameter γ that quantifies the gravitational modification

    We reconsider the Gram-Hadamard bound as it is used in constructive quantum field theory and many body physics to prove convergence of Fermionic perturbative expansions. Our approach uses a recursion for the amplitudes of the expansion, discovered in a model problem by Djokic (2013). It explains the standard way to bound the expansion from a new point of view, and for some of the amplitudes provides new bounds, which avoid the use of Fourier transform, and are therefore superior to the standard bounds for models like the cold interacting Fermi gas.

    1986-01-01

    In the oblique photon expansion, the collinear part of photon emission is summed up to all orders in perturbation theory. The number of oblique or non-collinear photons is the expansion order. Unlike in perturbation theory, every term of the expansion is both infrared finite and gauge invariant. The zero oblique photon contribution to the electromagnetic structure tensor in QED is computed in detail. The behaviors of the structure functions F1 and F2 are discussed in the soft and ultra-soft limits

    2014-06-01

    "Tiger Mother" Amy Chua provoked a culture clash with her claim that controlling parenting in Asian American (AA) contexts produces more successful children than permissive parenting in European American (EA) contexts. At the heart of this controversy is a difference in the normative models of self that guide behavior. Ideas and practices prevalent in AA contexts emphasize that the person is and should be interdependent with one's close others, especially one's mother. In contrast, EA contexts emphasize the person as independent, even from one's mother. We find that AA compared with EA high school students experience more interdependence with their mothers and pressure from them, but that the pressure does not strain their relationship with their mothers. Furthermore, following failure, AAs compared with EAs are more motivated by their mothers, and AAs are particularly motivated by pressure from their mothers when it conveys interdependence. © 2014 by the Society for Personality and Social Psychology, Inc.

    The United States (US) is the only developed country that does not guarantee short-term or longer-term paid sick leave. This study used a multiyear nationally representative database to examine the association between availability of paid sick leave and frequency of emergency department (ED) use among US private sector employees. We used the National Health Interview Survey data (2012-2014). The final study sample consists of 42,460 US adults between 18 and 64years of age and working in nongovernmental private sector. Our results suggest that availability of paid sick leave is significantly associated with lower likelihood of ED use, for both moderate (1-3 times/year) and repeated users (4 or more times/year). After controlling for confounding factors, respondents with paid sick leave are 14% less likely to be moderate ED users (adjusted odds ratio, 0.86; 95% CI, 0.79-0.93) and 32% less likely to be repeated ED users (adjusted odds ratio, 0.68; 95% CI, 0.50-0.91). Although expansion of health insurance coverage under the Affordable Care Act has not been shown to reduce utilization of high cost health care services such as the ED, our study suggests other factors such as the availability of paid sick leave may do so, by allowing patients to seek care through other more cost-effective mechanisms (eg, primary care providers). To reduce ED utilization, health policymakers should consider alternative reforms including paid sick leave. Copyright © 2016 Elsevier Inc. All rights reserved.

    The aim of this study is to investigate the effect of two chemical stabilizers on the swelling potential of expansive soil. A high plasticity sodium bentonite was used as the expansive soil. The additive materials including fly ash (FA) and lime (L) were evaluated as potential stabilizers to decrease the swelling pressure of bentonite. Depending on the type of additive materials, they were blended with bentonite in different percentages to assess the optimum state and approch the maximum swell pressure reduction. According to the results of swell pressure test, both fly ash and lime reduce the swelling potential of bentonite but the maximum improvement occurs using bentonite-lime mixture while the swelling pressure reduction approaches to 49%. The results reveal a significant reduction of swelling potential of expansive soil using chemical stabilizers. Keywords: Expansive soil; swell pressure; chemical stabilization; fly ash; lime

    1998-01-01

    The method of the large mass expansion (LME) is investigated for selfenergy and vertex functions in two-loop order. It has the technical advantage that in many cases the expansion coefficients can be expressed analytically. As long as only one non-zero external momentum squared, q 2 , is involved also the Taylor expansion (TE) w.r.t. small q 2 yields high precision results in a domain sufficient for most applications. In the case of only one non-zero mass M and only one external momentum squared, the expansion w.r.t. q 2 /M 2 is identical for the TE and the LME. In this case the combined techniques yield analytic expressions for many diagrams, which are quite easy to handle numerically. (author)

    1992-01-01

    Twelve adults with maxillary width discrepancy of greater than 5 mm were treated by surgically assisted rapid maxillary expansion. The procedure consisted of bilateral zygomatic buttress and midpalatal osteotomies combined with the use of a tooth-borne orthopedic device postoperatively. Mean palatal expansion of 7.5 mm (range of 6 to 13 mm), measured in the first molar region, was achieved within 3 weeks in all patients. Expansion remained stable during the 12-month study period, with a mean relapse for the entire group of 0.88 +/- 0.48 mm. Morbidity was limited to mild postoperative discomfort. The results of this preliminary study indicated that surgically assisted rapid maxillary expansion is a safe, simple, and reliable procedure for achieving a permanent increase in skeletal maxillary width in adults. Further study is necessary to document the three-dimensional movements of the maxillary segments and long-term stability of the skeletal and dental changes.

  2. Chemical graph-theoretic cluster expansions

    International Nuclear Information System (INIS)

    Klein, D.J.

    1986-01-01

    A general computationally amenable chemico-graph-theoretic cluster expansion method is suggested as a paradigm for incorporation of chemical structure concepts in a systematic manner. The cluster expansion approach is presented in a formalism general enough to cover a variety of empirical, semiempirical, and even ab initio applications. Formally such approaches for the utilization of chemical structure-related concepts may be viewed as discrete analogues of Taylor series expansions. The efficacy of the chemical structure concepts then is simply bound up in the rate of convergence of the cluster expansions. In many empirical applications, e.g., boiling points, chromatographic separation coefficients, and biological activities, this rate of convergence has been observed to be quite rapid. More note will be made here of quantum chemical applications. Relations to questions concerning size extensivity of energies and size consistency of wave functions are addressed

  3. Magnetized relativistic electron-ion plasma expansion

    Benkhelifa, El-Amine; Djebli, Mourad

    2016-03-01

    The dynamics of relativistic laser-produced plasma expansion across a transverse magnetic field is investigated. Based on a one dimensional two-fluid model that includes pressure, enthalpy, and rest mass energy, the expansion is studied in the limit of λD (Debye length) ≤RL (Larmor radius) for magnetized electrons and ions. Numerical investigation conducted for a quasi-neutral plasma showed that the σ parameter describing the initial plasma magnetization, and the plasma β parameter, which is the ratio of kinetic to magnetic pressure are the key parameters governing the expansion dynamics. For σ ≪ 1, ion's front shows oscillations associated to the break-down of quasi-neutrality. This is due to the strong constraining effect and confinement of the magnetic field, which acts as a retarding medium slowing the plasma expansion.

    The small distance expansion of the product of composite fields is constructed for an arbitrary renormalization procedure of the type of minimal subtraction scheme. Coefficient functions of the expansion are expressed explicitly through the Green functions of composite fields. The expansion has the explicity finite form: the ultraviolet (UV) divergences of the coefficient functions and composite fields are removed by the initial renormalization procedure while the infrared (IR) divergences in massless diagrams with nonvanishing contribution into the coefficient functions are removed by the R-operation which is the IR part of the R-operation. The latter is the generalization of the dimensional renormalization in the case when both UV and IR divergences are present. To derive the expansion, a ''pre-subtracting operator'' is introduced and formulas of the counter-term technique are exploited

  5. Treatment of divergent expansions in scattering theory

    International Nuclear Information System (INIS)

    Gersten, A.; Malin, S.

    1978-01-01

    One of the biggest obstacles in applying quantum field theory to realistic scattering problems are the divergencies of pertubation expansions for large coupling constants and the divergencies of partial wave expansions for massless particles exchanges. There exist, however, methods of summation of the divergent expansions which can lead to significant application in physics. In this paper we treat the problem of summing such expansions using three methods: (i) a generalization of the Pade approximation to the multivariable case. The suggested definition is unique and preserves unitarity. (ii) The summation of divergent partial waves for arbitrary spins. (iii) A successful application of a series inversion to the 3 P 1 nucleon-nucleon phase shift up to 200 MeV. (orig./WL) [de

  7. Secret-key expansion from covert communication

    Arrazola, Juan Miguel; Amiri, Ryan

    2018-02-01

    Covert communication allows the transmission of messages in such a way that it is not possible for adversaries to detect that the communication is occurring. This provides protection in situations where knowledge that two parties are talking to each other may be incriminating to them. In this work, we study how covert communication can be used for a different purpose: secret key expansion. First, we show that any message transmitted in a secure covert protocol is also secret and therefore unknown to an adversary. We then propose a covert communication protocol where the amount of key consumed in the protocol is smaller than the transmitted key, thus leading to secure secret key expansion. We derive precise conditions for secret key expansion to occur, showing that it is possible when there are sufficiently low levels of noise for a given security level. We conclude by examining how secret key expansion from covert communication can be performed in a computational security model.

  9. The dewetting properties of lotus leaves.

    Science.gov (United States)

    Zhang, Jihua; Sheng, Xianliang; Jiang, Lei

    2009-02-03

    The high dewetting abilities of lotus leaves can be transited to a complete wetting state by soaking the leaves in water at a depth of 50 cm for 2 h. However, after being dried by N2 gas, the high dewetting behavior of lotus leaves may be mostly restored. This indicates that experimental procedure might considerably affect the dewetting abilities of lotus leaves. To discover the mechanism underlying this interesting dewetting phenomena, the dewetting force was used to characterize the dewetting abilities of surfaces, and model studies to mimic the papillae were done. Surface hydrophobicity, sizes, rise angles, and secondary structures of the models' sides affected their dewetting force with water. So we suggested that the dewetting states, Cassie or Wenzel's state, of lotus surfaces depend much on the depth of water, i.e., the hydraulic pressure. On the other hand, the primary structures of papillae in Cassie's state led to a high receding angle with respect to the plane of the leaf during the dewetting measurement. The secondary structures and micro/nano arrays of papillae increased the dewetting abilities of lotus leaves, since no water intruded between papillae. However, the structures of papillae in Wenzle's state significantly reduced the dewetting abilities of lotus leaves after being soaked at a depth of 50 cm for 2 h. Therefore, as for novel designs of microdevices floating on water, including the use of the high dewetting properties of suphydrophobic materials, surface (primary or secondary) microstructure and external pressure, such as static hydraulic pressure, must be taken into account.

    Female labour force participation is high in Norway but sickness absence rates are higher for women than for men. This may be partly a result of unequal sharing of childcare in the family. In this paper, we consider the effect of paternity leave on sickness absence among women who have recently given birth. We draw on a six-year panel taken from full population data from administrative sources. We find that in the 6% of families where fathers take out leave more than the standard quota (gende...

    We present a method of calculating coefficients of gluon operators in the operator product expansion of two-point functions at short distance. It is based on a short-distance expansion of the singular part of the quark propagator in the gluon field, the latter being treated as external. We verify in full generality that the spin zero, gluon operator of dimension six does not contribute to the two-point functions of quark bilinears.

    1978-01-01

    Measurements have been made of the critical thermal expansion of single crystals of gadolinium, prepared by solid state electrotransport processing. Although the expansion data can be fitted to a simple power law with exponents lambda + =-0.25, lambda - =-0.33, these values are not predicted by theory and a discontinuity remains at Tsub(c)=293.620 K. It is suggested that the results relate to a region of crossover to uniaxial dipolar behaviour. (Auth.)

    1987-01-01

    Colored particle Green functions in vacuum background random fields are written as path integrals. Averaging over random fields is done using the cluster (cumulant) expansion. The existence of a finite correlation length for vacuum background fields is shown to produce the linear confinement, in agreement with the results, obtained with the help of averaged Hamiltonians. A modified form of cluster expansion for nonabelian fields is introduced using the path-ordered cumulants

  17. Composite asymptotic expansions and scaling wall turbulence.

    Science.gov (United States)

    Panton, Ronald L

    2007-03-15

    In this article, the assumptions and reasoning that yield composite asymptotic expansions for wall turbulence are discussed. Particular attention is paid to the scaling quantities that are used to render the variables non-dimensional and of order one. An asymptotic expansion is proposed for the streamwise Reynolds stress that accounts for the active and inactive turbulence by using different scalings. The idea is tested with the data from the channel flows and appears to have merit.

    Time-dependent perturbation theory as a tool to compute approximate solutions of the Schroedinger equation does not preserve unitarity. Here we present, in a simple way, how the Magnus expansion (also known as exponential perturbation theory) provides such unitary approximate solutions. The purpose is to illustrate the importance and consequences of such a property. We suggest that the Magnus expansion may be introduced to students in advanced courses of quantum mechanics.

    EXAFS can represent a powerful probe of the local behaviour of negative thermal expansion (NTE) materials, thanks to the possibility of measuring the expansion of selected inter-atomic bonds and the perpendicular relative atomic displacements. The effectiveness of EXAFS for NTE studies is illustrated by a comparison of results recently obtained on germanium, CuCl and the cuprites Cu 2 O and Ag 2 O

    1988-12-01

    The influence of socioeconomic status (ethnicity, income and parity) on electrolyte composition (sodium and potassium) in human milk is little known. We have thus quantitatively analyzed approximately 700 samples of milk (1-90 days postpartum) obtained from healthy Malaysian mothers' (Malay, Chinese and Indians) of full term infants. Results show that the mean concentration (mmol/l) of sodium is highest (48.2+or-1.7, Mean+or-SEM) in the Malaysian mothers' colostrum and this value decreased by 30% in their transitional milk and remained constant throughout subsequent days of lactation (mature milk). Ethnically, it is found that the level of sodium in colostrum of Malay and Chinese mothers were similar while the Indian mothers' colostrum showed apparently higher value (52.7+or-3.4 mmol/l) that is statistically insignificant. The transitional milk of all 3 ethnic groups studied exhibited similar levels of sodium. On subsequent days of lactation (mature milk) the Malay mothers exhibited lowest concentration (25.9+or-2.6 mmol/l) of sodium that is significantly (P0.05) different from that of Chinese and Indian mothers. Income and parity do not significantly affect the sodium level in Malaysian mothers' milk during all stages of lactation studied. The level of potassium, however did not change significantly with days of lactation. Like sodium, potassium too was not influenced by income and parity. (Author's).

    2013-10-01

    Many mothers work in jobs with nonstandard schedules (i.e., schedules that involve work outside of the traditional 9-5, Monday through Friday schedule); this is particularly true for economically disadvantaged mothers. In the present article, we used longitudinal data from the Fragile Families and Child Wellbeing Survey (n = 2,367 mothers of children ages 3-5 years) to examine the associations between maternal nonstandard work and children's behavior problems, with a particular focus on mothers' night shift work. We employed 3 analytic strategies with various approaches to adjusting for observed and unobserved selection factors; these approaches provided an upper and lower bound on the true relationship between night shift work and children's behavior. Taken together, the results provide suggestive evidence for modest associations between exposure to maternal night shift work and higher levels of aggressive and anxious or depressed behavior in children compared with children whose mothers who are not working, those whose mothers work other types of nonstandard shifts, and, for aggressive behavior, those whose mothers work standard shifts.

  7. Thermal expansion behavior in fabricated cellular structures

    2004-01-01

    Thermal expansion behavior of cellular structures is of interest in applications where undesirable deformation and failure are caused by thermal expansion mismatch. This report describes the role of processing-induced effects and metallurgical aspects of melt-processed cellular structures, such as a bi-material structure designed to contract on heating, as well as uni-material structures of regular and stochastic topology. This bi-material structure utilized the principle of internal geometric constraints to alter the expansion behavior of the internal ligaments to create overall contraction of the structure. Homogenization design method was used to design the structure, and fabrication was by direct metal deposition by laser melting of powder in another part of a joint effort. The degree of porosity and grain size in the fabricated structure are characterized and related to the laser deposition parameters. The structure was found to contract upon heating over a short range of temperature subsequent to which normal expansion ensued. Also examined in this report are uni-material cellular structures, in which internal constraints arise from residual stress variations caused by the fabrication process, and thereby alter their expansion characteristics. A simple analysis of thermal strain of this material supports the observed thermal expansion behavior

    Full Text Available Objective: To verify the presence of depression, age, level of schooling, occupation, marital status, number of children and nutritional status (maternal and of the child in mothers of overweight and eutrophic children and relate the data to mother/child bonding. Methods: A total of 120 mothers of children aged up to 10 years participated; 30 of them were overweight and 30 were eutrophic (low-income bracket; 30 were overweight and 30 eutrophic (high-income bracket. The control group was composed of eutrophic children paired according to sex, age, level of schooling, and social condition. Data collection was made through interviews. The assessment instruments were: Mother/Child Bonding Assessment Protocol and Beck Depression Inventory. The nutritional classification was defined by calculation of the body mass index, as per the curves of the World Health Organization. For statistics, McNemar, χ2, and Fisher’s exact tests were used. A 5% level of rejection of the null hypothesis was set. Results: There was no significant result between mother/child bonding and the variables studied, or between the presence of depression and level of schooling, marital status, occupation, and maternal nutritional status. Nevertheless, mothers of eutrophic children (high-income bracket showed less depression than mothers of eutrophic children (low-income bracket. Mothers with three or more children displayed more depression than mothers with less than three children. Mothers under 30 years of age showed more depression than mothers aged 30 years or older. Conclusion: There was no significant result between mother/child bonding and the variables studied, but the bond was compromised in all mothers of the sample. There was a significant result regarding the presence of depression.

    Preterm babies are more prone to develop disorders and so require immediate intensive care. In the conventional neonatal intensive care, the baby is kept in the incubator, separated from the mother. Some actions have been taken in order to make this mother-child separation less traumatic. One of these actions is the Kangaroo mother care (KMC) characterized by skin-to-skin contact between a mother and her newborn. The objective of this study was to compare the mood variation of mothers enrolled in the KMC program to those in the conventional incubator care. In one general hospital in Sao Paulo, Brazil, 90 mothers were evaluated before and after contact with the baby in the Neonatal Intensive Care Unit. The participants were divided into three groups: 30 mothers of term newborns (TG), 30 mothers of preterm infants included in KMC program (PGK) and 30 preterms with incubator placement (PGI). The Brazilian version of the Visual Analogue Mood Scale (VAMS) was used for the assessment before and after the infant's visit. Results showed that TG mothers reported fewer occurrences of depressive states than PGK and PGI mothers. A significant mood variation was observed for PGK and PGI after the infant's visit. PGK mothers reported feeling calmer, stronger, well-coordinated, energetic, contented, tranquil, quick-witted, relaxed, proficient, happy, friendly and clear-headed. The only variation showed by PGI mothers was an increase in feeling clumsy. This study shows a positive effect of the KMC on the mood variation of preterm mothers and points to the need of a more humane experience during the incubator care.

    Two types of single-parent households and their effects on children ages 3-11 years were compared. One type comprised 50 homosexual mothers and their 56 children, and the other was a group of 40 heterosexual mothers and their 48 children. There were 30 daughters and 26 sons of homosexual mothers and 28 daughters and 20 sons of heterosexual mothers. The sexual identity and social relationships of the children were assessed in relation to the sexual orientation of the mothers. The samples consisted of families from rural and urban areas in 10 American states. All have lived without adult males (18 years or older) in the household for a minimum of 2 years (average 4). Families with heterosexual mothers were matched to families with homosexual mothers on age and race of mother; length of mother and child separation from father; educational level and income of mother; and number, age, and sex of children. Data are reported from childrens' tests designed to provide information on general intelligence, core-morphologic sexual identity, gender-role preferences, family and peer group relationships, and adjustment to the single-parent family. No significant differences were found between the two types of households for boys and few significant differences for girls. Concerns that being raised by a homosexual mother might produce sexual identity conflict and peer group stigmatization were not supported by the research findings. Data also revealed more similarities than differences in parenting experiences, marital history, and present living situations of the two groups of mothers. The postulated compromised parental fitness of lesbian mothers, commonly asserted in child custody cases, is not supported by these data.

  11. Ethylene and carbon dioxide exchange in leaves and whole plants

    Woodrow, L

    1989-01-01

    This investigation addresses the interactions between CO{sub 2}, ethylene, and photosynthetic carbon metabolism in Lycopersicon esculentum Mill. and Xanthium strumarium L. Rates of ethylene release were examined at alternate leaf positions on vegetative tomato plants. The rates of endogenous and ACC-stimulated ethylene release per unit leaf area were highest in the young, rapidly expanding leaves. When plants were grown under CO{sub 2} enrichment rates of ethylene release from the leaf tissue were consistently higher than from tissue grown at ambient levels. Elevated CO{sub 2} concentrations during short-term incubations further enhanced the rates of ethylene release. Ethylene release from ethephon (2-chloroethylphosphonic acid) applied to intact tomato plants provided a model system in which to study the effects of ethylene on photosynthetic metabolism and carbon partitioning. The ethephon treated plants exhibited leaf epinasty, flower bud abscission, inhibition of leaf expansion, adventitious root development, and reduction of dry matter accumulation and growth over time. Rates of steady state photosynthesis, respiration, photorespiration, transpiration, and partitioning of recently fixed {sup 14}C into neutral, acidic, basic, and insoluble leaf fractions were unaltered 24 h after ethephon application.

    In some states, the Temporary Assistance for Needy Families (TANF) program offers the equivalent of paid maternity leave without job protection to low-income, single mothers of infants. Age-of-youngest-child (AYC) exemptions waive work requirements for TANF recipients after the birth of a child, generally for 3–12 months, depending on the state. This study uses data from the Current Population Survey (1998–2008) to examine whether the availability and length of AYC exemptions are predictive of rates of employment, work, and full-time work among low-educated single mothers with infants. The analysis uses the difference-in-differences (DD) technique, a comparison of outcomes under different policy treatments and between treatment and comparison groups. The results suggest that AYC exemptions are not related to employment or work rates but that living in a state with no AYC exemption is strongly and positively associated with rates of full-time work among low-educated mothers with infants.

  17. Thin foil expansion into a vacuum

    International Nuclear Information System (INIS)

    Mora, P.

    2005-01-01

    Plasma expansion into a vacuum is an old problem which has been renewed recently in various contexts: expansion of ultra-cold plasmas, cluster expansion, of dust grains, expansion of thin foils. In this presentation I will first discuss the physics of the expansion of a thin foil irradiated by an ultra-short ultra-intense laser pulse. The expansion results in the formation of high energy ions. For an infinitely steep plasma-vacuum interface the fastest ions are located in the outer part of the expansion and their velocity is given by ν m ax∼ 2 C s (In ω p it) where c s (Zk B T e /m i )''1/2 is the ion-acoustic velocity ω p i=(n e 0Ze''2/m i e 0 )''1/2 is the ion plasma frequency, n e 0 is the electron density in the unperturbed plasma, Z is the ion charge number. In the above expression, t is either the pulse duration or the effective acceleration time (in particular t∼L/2c s , where L is the width of the foil, when the electron cooling is taken into account). A salient characteristic of the expansion is the occurrence of a double layer structure and a peak of the accelerating electric field at the ion front. I will explain the origin of the peak and predict its temporal behavior. This peak has been diagnosed in recent experiments. I will also discuss the effect of a 2-temperatures electron distribution function on the expansion, showing the dominant role of the hot electron component. Finally I will discuss the occurrence of ion spikes in the expansion when the initial density profile is smooth. The ion spike is due to a wave breaking which cannot be handled in a satisfactory way by a fluid code and requires a kinetic description. A. simple collisionless particle code has been used to treat the evolution of the spike after the wave breaking and the results will be shown. (Author)

The investigated species were: lemon balm (Mellisa officinalis L., common lavender (Lavendula angustifolia Mill., horsemint (Mentha longifolia L., sage (Salvia officinalis L., sweet basil (Ocimum basilicum L., and wild marjoram (Origanum vulgare L.. The aim of the investigation was to identify fungi causing the death of leaf tissues of herbs from the mint family Lamiaceae. In mycological investigations, 180 fragments of each plant leaves (1,080 dead leaf fragments in total were placed in a 2% PDA medium. Over 970 colonies of fungi belonging to 48 species were isolated from the dead leaf tissues of the six herb species. Alternaria alternata (toxin-producing, Epicoccum nigrum and Sordaria fimicola were the most frequently isolated. The largest numbers of colonies and species of fungi were isolated from horsemint, while the lowest numbers were from wild marjoram leaves. It was shown that the death of leaves of selected herb species from the Lamiaceae family was caused by various fungi. The results of the mycological analysis confirmed the diversity of species colonizing the leaves of the herbs.

    Radioactive contamination of foodstuffs attributed to the Fukushima Daiichi nuclear disaster has become a social problem. This study investigated the extraction of radioactive cesium from the contaminated leaves to the tea. The green tea was brewed twice reusing the same leaves to study the difference in extraction of cesium between the first and second brew. Moreover, the extraction of cesium was studied in correlation to brewing time. The concentration of radioactive cesium was determined with gamma spectrometry, and the concentration of caffeine was determined with absorption spectrometry. About 40% of cesium was extracted from leaves in the first brew, and about 80% was extracted in the second brew. The extraction of cesium increased over time, and it reached about 80% after 10 minutes brew. The ratio of radioactive cesium to caffeine decreased linearly over time. This study revealed that the extraction of cesium was higher for the second brew, and a rapid increase in extraction was seen as the tea was brewed for 6 minutes and more. Therefore, the first brew of green tea, which was brewed within 5 minutes, contained the least extraction of radioactive cesium from the contaminated leaves. (author)

    Parental leave is linked to health benefits for both child and parent. It is unclear whether surgeons at academic centers have access to paid parental leave. The aim of this study was to determine parental leave policies at the top academic medical centers in the United States to identify trends among institutions. The top academic medical centers were identified (US News & World Report 2016). Institutional websites were reviewed, or human resource departments were contacted to determine parental leave policies. "Paid leave" was defined as leave without the mandated use of personal time off. Institutions were categorized based on geographical region, funding, and ranking to determine trends regarding availability and duration of paid parental leave. Among the top 91 ranked medical schools, 48 (53%) offer paid parental leave. Availability of a paid leave policy differed based on private versus public institutions (70% versus 38%, P leaves (>6 wk) than public institutions (67% versus 33%; P = 0.02). No difference in paid leave duration was noted based on region (P = 0.60) or rank (P = 0.81). Approximately, 50% of top academic medical centers offer paid parental leave. Private institutions are more likely to offer paid leave and leave of longer duration. There is considerable variability in access to paid parenteral leave for academic surgeons.

    Adolescent period is the transitional stage of physical and mental development from childhood to adulthood. Pregnancy in teenage girls is generally classified to have a higher risk than those in adults. In many previous studies reported only the outcome of teenage mothers but no comparative outcome between sick babies born to teen mothers and adult mothers, so the authors conducted the present study. To compare the outcomes of sick infants born to teenage mothers with those born to adult mothers (age > or = 20 years). This prospective study was carried out from October 1st, 2006 to September 30th, 2009. The study group consisted of sick babies born to teenage mothers and admitted at Queen Sirikit National Institute of Child Health (QSNICH). These babies were compared to sick babies (control group) born to adult mothers during the same period. The demographic data of mothers and sick babies in both groups were recorded in the designed case record forms. Developmental assessment was done until two years of age. A total of 6,342 deliveries took place in Rajavithi Hospital during the study period of which 697 babies were born to teenage mothers. The incidence of teenage pregnancy was 10.99%. The number of sick babies from teenage mothers and adult mothers were 78 and 147 cases, respectively. There was a significantly higher mortality in the study group (7 cases, 9%) than the control group (4 cases, 2.7%). There was statistically significant difference in most of the demographic characteristics between the teenage and adult mothers except anemia, PROM and MSAF (meconium stain amniotic fluid). Although there was a trend of more cases of anemia and MSAF in teenage mothers than in adult mothers, there was no statistically significant difference. There was a shorter interval time from marriage to pregnancy in teen mothers than in adult mothers and a lower number of antenatal care visits with late antenatal care among the teenage mothers too. On comparing the data in infants

    The role of "mother" is understood and represented differently by people from different cultures. In traditional Taiwanese society, mothers demonstrate their existence value by giving birth to and raising sons able to continue her husband's familial line. Sons bear the patriarchal name and care for their parents in old age. However, a son stricken, paralyzed and eventually killed by Duchenne muscular dystrophy (DMD) can destroy a mother's perceived value in this traditional social context. Mothers are thus soundless sufferers. Nurses have a critical role to play in giving encouragement and hope to mothers of children with DMD. Through their own difficult situation, these mothers can also highlight the value and importance of Taiwan's nurses, who work in conditions marked by overloading, high stress, and under-appreciation. Caring for women in critical need of empathy and support help nurses realize their own positive capacity to empower sufferers.

    This study aims to describe the lived experiences of Filipina mothers married to Japanese during pregnancy and childrearing. Eight focus group interviews (FGI) were conducted among 39 Filipino mothers who are currently residing in Japan to obtain significant information with regard to their pregnancy and childrearing experiences. Content analysis was used to extract relevant themes that will describe the experiences of this group of migrant mothers. The findings revealed three major themes: 1) cultural barriers during pregnancy and childrearing; 2) mothering at the different stages of childrearing; and 3) positive adjustments to a new role in a new environment. The establishment of means of communication with migrant mothers effectively enabling them to understand important information for promoting healthy pregnancy and childrearing is strongly recommended. Provision of school information in the English language and enhancing the resilient character of the Filipina are important strategies in promoting positive pregnancy and childrearing experiences among Filipina migrant mothers.

    The transfer of radionuclides from mother to embryo is still a matter of high interest. Therefore, the relation was investigated between the amount of radionuclides in the embryo and the dietary intake of the mother, this for two scenarios: a recurrent intake of variable amounts of radionuclides, and a long-term intake of a relatively constant amount of radionuclides, the radionuclide being 137 Cs. In the first case, the amount of radionuclides present in the embryo increases with the age of the embryo and with the intake of the mother. In the second case, no correlation could be found between the age of the embryo and its radioactive content; only the correlation between the intake of the mother and the radionuclide content of the embryo remained.

    2011-04-01

    Working mothers experience several barriers to physical activity. If these barriers can be identified by occupational health nurses and they can partner with working mothers to reduce these perceived barriers, the health of these workers can be improved and chronic disease risk prevented. The purpose of this study was to measure the effect of self-regulatory efficacy on physical activity among working mothers and to describe specific barriers to physical activity. The Barriers Specific Self-Efficacy Scale (BARSE) and the Kaiser Physical Activity Survey (KPAS) were used to measure the variables. Self-regulatory efficacy was found to be a strong predictor of physical activity in a diverse sample of working mothers who did not meet current recommendations for physical activity. Occupational health nurses can use these findings to design programs for groups and for counseling individuals. Copyright 2011, SLACK Incorporated.

    This research project aimed to determine the factors for the transfer of the elements silver (Ag), cerium (Ce), cobalt (Co), chrome (Cr), gallium (Ga), lanthanum (La), molybdenum (Mo), niobium (Nb), radium (Ra), ruthenium (Ru), antimony (sb), thorium (Th), titanium (Ti) and uranium (U) from food into the mother's milk. This factors will be used as a basic to check and derive activity values for the contamination of food and for radiation protection at working places of suckling women. For this purpose 19 mothers collected samples daily (2-8 weeks), using the duplicate method, of all the food they consumed as well as of their milk. After microwave-assisted digestion the element contents were analysed by mass-spectroscopy with inductive coupled plasma (ICP-MS). The results of the mothers who participate for more than 5 weeks were used to make a time lapse between the intake and transfer of the elements in the mothers milk visible. (orig.) [de

    There has been little previous work on the toughness of the laminae of monocots in tropical lowland rain forest (TLRF) despite the potential importance of greater toughness in inhibiting herbivory by invertebrates. Of 15 monocot families with >100 species in TLRF, eight have notably high densities of fibres in the lamina so that high values for toughness are expected. In north-eastern Australia punch strength was determined with a penetrometer for both immature leaves (approx. 30 % final area on average) and fully expanded, fully toughened leaves. In Singapore and Panama, fracture toughness was determined with an automated scissors apparatus using fully toughened leaves only. In Australia punch strength was, on average, 7x greater in shade-tolerant monocots than in neighbouring dicots at the immature stage, and 3x greater at the mature stage. In Singapore, shade-tolerant monocots had, on average, 1.3x higher values for fracture toughness than neighbouring dicots. In Panama, both shade-tolerant and gap-demanding monocots were tested; they did not differ in fracture toughness. The monocots had markedly higher values than the dicots whether shade-tolerant or gap-demanding species were considered. It is predicted that monocots will be found to experience lower rates of herbivory by invertebrates than dicots. The tough monocot leaves include both stiff leaves containing relatively little water at saturation (e.g. palms), and leaves which lack stiffness, are rich in water at saturation and roll readily during dry weather or even in bright sun around midday (e.g. gingers, heliconias and marants). Monocot leaves also show that it is possible for leaves to be notably tough throughout the expansion phase of development, something never recorded for dicots. The need to broaden the botanist's mental picture of a 'tough leaf' is emphasized.

    2013-07-01

    Obesity is associated with risks for mother and infant, and the mothers' dietary habits influence breast milk composition. Polyamines are secreted in breast milk and are essential for the regulation of intestinal and immune function in newborns and infants. The present study aimed to investigate the level of polyamines in human milk obtained from obese and normal weight mothers at different times of lactation. Breast milk from 50 mothers was obtained at day 3, and at 1 and 2 months after delivery. The mothers had normal body weight [body mass index (BMI) obese (BMI > 30 kg/m(2) ). A subgroup of obese mothers participated in a weight reduction programme during pregnancy. Polyamines were analysed using high-performance liquid chromatography. The total polyamine content was significantly lower at all times in breast milk from obese mothers compared to milk from controls. Spermine levels did not differ between groups at any time in contrast to the levels of putrescine and spermidine. Putrescine concentrations were highest on day 3 and spermidine and spermine were highest at 1 month of lactation. The obese mothers, who received dietary advice during pregnancy based on the Nordic Nutrition Recommendations, had higher concentrations of putrescine and spermidine in their milk than the obese mothers without any intervention. Polyamine concentrations were lower in breast milk from obese mothers compared to mothers with a normal weight. General dietary intervention in obese mothers increased the polyamine levels, suggesting that the low levels in obesity were at least partly associated with food habits. However, the consistency of spermine suggests a special metabolic function of this polyamine. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

    Mizuno-Lewis, Satomi; McAllister, Margaret

    2008-01-01

    This paper provides an overview of nurses' working conditions in Japan, exploring tensions between nurses' rights to take leave from work to fulfil family and personal needs and their actual ability to take such leave. It also considers possible effects of being restricted from taking such leave. Little has been written on the specific needs of nurses who are mothers in the Japanese work environment. Research has focussed on the effects of heavy, stressful workloads and long working hours leading to burnout, death from overwork and suicides in Japanese culture. However, research that considers unique cultural and female issues in Japan affecting nursing work has not been published. Discursive. The paper shows that there are many overlapping, complex issues affecting nurses working in Japan and their needs need to be considered and addressed in order to promote a healthier work environment, as well as a more humanistic environment. Workplace issues are relevant to recruitment and retention and better conditions are likely to improve hospital functioning.

    Sick leave can be envisaged as an important public health indicator. Health problems and trouble at work are predictors of absenteeism. Within the context of reforming the judicial system, the aim of this study was to examine whether individual characteristics and working conditions influenced reports of sick leave amongst a population of Brazilian magistrates. A web-based survey was conducted in 2011 in such a way as to reach the entire population of Brazilian Labor-law magistrates across the country. The variable of interest related to the question: "Have you taken any medical leave due to illness over the last 12 months?" Less than a quarter of the population participated in the survey, despite widespread publicity produced by the professional association. Among the work-related factors, experiences of violence in the courthouse were shown to be associated with the outcome. No significant association with the material or psychosocial working conditions or with the workload was found. Female, worse health assessment, not participating in social activities and having a mother with higher schooling level were significantly associated with absenteeism among the magistrates. It is desirable to formulate sectorial policies focusing on controlling and monitoring violent events in the courthouse.

  14. Expansion Under Climate Change: The Genetic Consequences.

    Science.gov (United States)

    Garnier, Jimmy; Lewis, Mark A

    2016-11-01

    Range expansion and range shifts are crucial population responses to climate change. Genetic consequences are not well understood but are clearly coupled to ecological dynamics that, in turn, are driven by shifting climate conditions. We model a population with a deterministic reaction-diffusion model coupled to a heterogeneous environment that develops in time due to climate change. We decompose the resulting travelling wave solution into neutral genetic components to analyse the spatio-temporal dynamics of its genetic structure. Our analysis shows that range expansions and range shifts under slow climate change preserve genetic diversity. This is because slow climate change creates range boundaries that promote spatial mixing of genetic components. Mathematically, the mixing leads to so-called pushed travelling wave solutions. This mixing phenomenon is not seen in spatially homogeneous environments, where range expansion reduces genetic diversity through gene surfing arising from pulled travelling wave solutions. However, the preservation of diversity is diminished when climate change occurs too quickly. Using diversity indices, we show that fast expansions and range shifts erode genetic diversity more than slow range expansions and range shifts. Our study provides analytical insight into the dynamics of travelling wave solutions in heterogeneous environments.

  15. Simplified Technique for Predicting Offshore Pipeline Expansion

    2018-06-01

    In this study, we propose a method for estimating the amount of expansion that occurs in subsea pipelines, which could be applied in the design of robust structures that transport oil and gas from offshore wells. We begin with a literature review and general discussion of existing estimation methods and terminologies with respect to subsea pipelines. Due to the effects of high pressure and high temperature, the production of fluid from offshore wells is typically caused by physical deformation of subsea structures, e.g., expansion and contraction during the transportation process. In severe cases, vertical and lateral buckling occurs, which causes a significant negative impact on structural safety, and which is related to on-bottom stability, free-span, structural collapse, and many other factors. In addition, these factors may affect the production rate with respect to flow assurance, wax, and hydration, to name a few. In this study, we developed a simple and efficient method for generating a reliable pipe expansion design in the early stage, which can lead to savings in both cost and computation time. As such, in this paper, we propose an applicable diagram, which we call the standard dimensionless ratio (SDR) versus virtual anchor length (L A ) diagram, that utilizes an efficient procedure for estimating subsea pipeline expansion based on applied reliable scenarios. With this user guideline, offshore pipeline structural designers can reliably determine the amount of subsea pipeline expansion and the obtained results will also be useful for the installation, design, and maintenance of the subsea pipeline.

    A major variable in evaluating the potential of silicic tuffs for use in geologic disposal of heat-producing nuclear wastes is thermal expansion. Results of ambient-pressure linear expansion measurements on a group of tuffs that vary treatly in porosity and mineralogy are presente here. Thermal expansion of devitrified welded tuffs is generally linear with increasing temperature and independent of both porosity and heating rate. Mineralogic factors affecting behavior of these tuffs are limited to the presence or absence of cristobalite and altered biotite. The presence of cristobalite results in markedly nonlinear expansion above 200 0 C. If biotite in biotite-hearing rocks alters even slightly to expandable clays, the behavior of these tuffs near the boiling point of water can be dominated by contraction of the expandable phase. Expansion of both high- and low-porosity tuffs containing hydrated silicic glass and/or expandable clays is complex. The behavior of these rocks appears to be completely dominated by dehydration of hydrous phases and, hence, should be critically dependent on fluid pressure. Valid extrapolation of the ambient-pressure results presented here to depths of interest for construction of a nuclear-waste repository will depend on a good understanding of the interaction of dehydration rates and fluid pressures, and of the effects of both micro- and macrofractures on the response of tuff masss

    Brazil is one of the world's leading producers and exporters of agricultural goods. Despite undergoing significant increases in its cropland area in the last decades, it remains one of the countries with the most potential for further agricultural expansion. Most notably, the expansion in production areas of commodity crops such as soybean, corn, and sugarcane has become the leading cause of land cover conversion in Brazil. Natural land covers, such as the Amazon and Cerrado forests, have been negatively affected by this agricultural expansion, causing carbon emissions, biodiversity loss, altered water cycles, and many other disturbances to ecosystem services. Monitoring of change in cropland area extent can provide relevant information to decision makers seeking to understand and manage land cover change drivers and their impacts. In this study, the freely-available Landsat archive was leveraged to produce a large-scale, methodologically consistent map of cropland cover at 30 m. resolution for the entire Brazilian territory in the year 2000. Additionally, we mapped cropland expansion from 2000 to 2013, and used statistical sampling techniques to accurately estimate cropland area per Brazilian state. Using the Global Forest Change product produced by Hansen et al. (2013), we can disaggregate forest cover loss due to cropland expansion by year, revealing spatiotemporal trends that could advance our understanding of the drivers of forest loss.

  18. Hematoma Expansion Following Acute Intracerebral Hemorrhage

    2013-01-01

    Intracerebral hemorrhage, the most devastating form of stroke, has no specific therapy proven to improve outcome by randomized controlled trial. Location and baseline hematoma volume are strong predictors of mortality, but are non-modifiable by the time of diagnosis. Expansion of the initial hematoma is a further marker of poor prognosis that may be at least partly preventable. Several risk factors for hematoma expansion have been identified, including baseline ICH volume, early presentation after symptom onset, anticoagulation, and the CT angiography spot sign. Although the biological mechanisms of hematoma expansion remain unclear, accumulating evidence supports a model of ongoing secondary bleeding from ruptured adjacent vessels surrounding the initial bleeding site. Several large clinical trials testing therapies aimed at preventing hematoma expansion are in progress, including aggressive blood pressure reduction, treatment with recombinant factor VIIa guided by CT angiography findings, and surgical intervention for superficial hematomas without intraventricular extension. Hematoma expansion is so far the only marker of outcome that is amenable to treatment and thus a potentially important therapeutic target. PMID:23466430

    Full Text Available The expansion of power transmission systems is an important part of the expansion of power systems that requires enormous investment costs. Since the construction of new transmission lines is very expensive, it is necessary to choose the most efficient expansion plan that ensures system security with a minimal number of new lines. In this paper, the role of Flexible AC Transmission System (FACTS devices in the effective operation and expansion planning of transmission systems is examined. Effort was taken to implement a method based on sensitivity analysis to select the optimal number and location of FACTS devices, lines and other elements of the transmission system. Using this method, the transmission expansion plan for a 9 and a 39 bus power system was performed with and without the presence of FACTS with the use of DPL environment in Digsilent software 15.1. Results show that the use of these devices reduces the need for new transmission lines and minimizes the investment cost.

  20. Thermal expansion of fibre-reinforced composites

    1991-07-01

    The integral thermal expansion and the coefficient of thermal expansion (CTE) of carbon and Kevlar fibre-reinforced composites were measured with high accuracy from 5 K to room temperature. For this, a laser dilatometer and a sophisticated measuring procedure were used. CTE dependence on the orientation angle ω of angle-ply laminates was determined for samples with 5 different fibre alignments (UD 0deg, +/-30deg, +/-45deg, +/-60deg and UD 90deg). A high variability of the CTE with the orientation angle was shown. At angles of approximately +/-30deg even negative CTEs were found. With suitable reinforcing fibres being selected, their absolute values rose up to 30-100% of the positive CTEs of metals. Hence, composites of this type would be suitable as compensating materials in metal constructions where little thermal expansion is desired. To check the lamination theory, theoretical computations of the CTE- ω -dependence were compared with the measured values. An excellent agreement was found. Using the lamination theory, predictions about the expansion behaviour of angle-ply laminates can be made now, if the thermal and mechanical properties of the unidirectional (UD) laminate are known. Furthermore, it is possible to carry out simulation computations aimed at investigating the influence of a single parameter of the UD-laminate (e.g. shear modulus) on the expansion of the angle-ply laminate.

    Maternal substance abuse is a critical problem, and adolescent mothers appear to be at high risk for such behaviors. We review studies on postpartum adolescent substance use to explore the extent of this problem and avenues for new research. Authors screened 1,300 studies, identifying 12 articles on substance use among postpartum adolescent mothers for this review. Adolescent mothers reported greater substance use before pregnancy compared to other adolescent females. Although some adolescents continued substance use during pregnancy, most stopped using only to resume within six months after birth. Comparisons of use to national samples of nulliparous adolescent females showed a higher prevalence of substance use in this population. Substances used often varied by race/ethnicity, with white mothers more likely to smoke cigarettes and use marijuana, and Black mothers more likely than whites to drink and use drugs. Of all identified studies, only one focused on Hispanics. Beliefs about drug use grew less negative as girls transitioned from pregnancy to parenthood. As they transitioned to adulthood, substance use remained prevalent and stable. Psychological distress and low self-esteem appeared to influence continued use. Friends' cigarette smoking predicted early initiation of and persistent smoking, while increased education predicted quitting. Early initiation of substances often predicted problem behaviors. Adolescent mothers are a vulnerable population, implicating use of problem behavior theory or the self-medication hypothesis in future research. Multiple avenues for new studies are needed to help identify effective treatment and intervention for this understudied population.

    Full Text Available Introduction: A deaf child creates a feeling of stigma in many hearing parents. Stigma in mothers can have a negative impact on a child’s treatment and rehabilitation process. Therefore, this study was conducted to evaluate the extent of stigma in mothers with deaf children.  Materials and Methods: This descriptive, cross-sectional study was conducted in 2013 among 90 mothers with deaf children. The data-collection instrument included the stigma scale in the mothers of children with disabilities. The reliability and validity of the instrument were confirmed through content validity and Cronbach’s alpha coefficient (α=86%, respectively. Data were analyzed using SPSS-15 software.   Results: Results showed that most mothers suffer from stigma due to having a deaf child. The mean stigma score was 96.48 ±27.72. In total, 24.4% of mothers reported that they had received strange and mocking looks; 72.2% regarded child deafness as a sign of divine retribution; and 33.3% felt ashamed of their child’s deafness. There was an inverse relationship between the mother’s level of education and mean stigma scores (P

    This study examined the motivations, experiences and psychological consequences of surrogacy for surrogate mothers. Thirty-four women who had given birth to a surrogate child approximately 1 year previously were interviewed by trained researchers, and the data rated using standardized coding criteria. Information was obtained on: (i) reasons for the woman's decision to become a surrogate mother; (ii) her retrospective view of the relationship with the commissioning couple before the pregnancy, during the pregnancy, and after the birth; (iii) her experiences during and after relinquishing the child; and (iv) how others reacted to her decision to become a surrogate mother. It was found that surrogate mothers do not generally experience major problems in their relationship with the commissioning couple, in handing over the baby, or from the reactions of those around them. The emotional problems experienced by some surrogate mothers in the weeks following the birth appeared to lessen over time. Surrogate mothers do not appear to experience psychological problems as a result of the surrogacy arrangement.

    To examine mothers' postpartum perceptions of stress and satisfaction. Methodologic triangulation with quantitative and qualitative data in a nonexperimental design. A convenience sample of 95 women was obtained during normally scheduled postpartum appointments at a health maintenance organization. The self-administered questionnaire included the Mothers' Information Tool (MIT), What Being the Parent of a Baby Is Like (WPL-R), and the Brief Symptom Inventory (BSI). Open-ended MIT items revealed mothers' perceptions of stress and satisfaction. The WPL-R provided maternal satisfaction scores, and the BSI yielded Global Stress Index scores. Content analysis identified the following categories: Roles, Tasks, Resources, and Relationships. Subcategories identified as areas of stress were Work/School, Sleep/Rest, Adjustment/Own Needs, Health/Body Image, Organization of Life, Child Care, Day Care, Housework, Future Challenges, Finances, Housing, Time, Partner, and Family. Subcategories identified as areas of satisfaction were Participating in Relationships, Sharing the Future, Being Proud to Be a Mother, Enjoying a Healthy Baby, and Caring for a Child. Levels of stress and satisfaction of mothers who scored high and low on quantitative measures were compared. The outcomes contribute to the knowledge concerning postpartum women's perceptions of the mothering experience and suggest approaches to nursing assessment and intervention to prevent postpartum adjustment difficulties.

  12. Women's Reasons for Leaving the Engineering Field.

    Fouad, Nadya A; Chang, Wen-Hsin; Wan, Min; Singh, Romila

    2017-01-01

    Among the different Science, Technology, Engineering, and Math fields, engineering continues to have one of the highest rates of attrition (Hewlett et al., 2008). The turnover rate for women engineers from engineering fields is even higher than for men (Frehill, 2010). Despite increased efforts from researchers, there are still large gaps in our understanding of the reasons that women leave engineering. This study aims to address this gap by examining the reasons why women leave engineering. Specifically, we analyze the reasons for departure given by national sample of 1,464 women engineers who left the profession after having worked in the engineering field. We applied a person-environment fit theoretical lens, in particular, the Theory of Work Adjustment (TWA) (Dawis and Lofquist, 1984) to understand and categorize the reasons for leaving the engineering field. According to the TWA, occupations have different "reinforcer patterns," reflected in six occupational values, and a mismatch between the reinforcers provided by the work environment and individuals' needs may trigger departure from the environment. Given the paucity of literature in this area, we posed research questions to explore the reinforcer pattern of values implicated in women's decisions to leave the engineering field. We used qualitative analyses to understand, categorize, and code the 1,863 statements that offered a glimpse into the myriad reasons that women offered in describing their decisions to leave the engineering profession. Our results revealed the top three sets of reasons underlying women's decision to leave the jobs and engineering field were related to: first, poor and/or inequitable compensation, poor working conditions, inflexible and demanding work environment that made work-family balance difficult; second, unmet achievement needs that reflected a dissatisfaction with effective utilization of their math and science skills, and third, unmet needs with regard to lack of recognition

    Materials with zero thermal expansion (ZTE) or precisely tailored thermal expansion are in urgent demand of modern industries. However, the overwhelming majority of materials show positive thermal expansion. To develop ZTE or negative thermal expansion (NTE) materials as compensators has become an important challenge. Here, we present the evidence for the realization of ultra-low thermal expansion in Mn-Co-Ge-In particles. The bulk with the Ni2In-type hexagonal structure undergoes giant NTE owing to a martensitic magnetostructural transition. The major finding is that the thermal expansion behavior can be totally controlled by modulating the crystallinity degree and phase transition from atomic scale. Self-compensation effect leads to ultra-low thermal expansion with a linear expansion coefficient as small as +0.68 × 10-6/K over a wide temperature range around room temperature. The present study opens an avenue to reach ZTE particularly from the large class of giant NTE materials based on phase transition.

    1977-01-21

    A theoretical description of a free supersonic expansion process is given. Three distinct regions in the expansion are discussed, namely the continuum region, the gradual transition to the collisionless regime, and the free-molecular-flow stage. Important topics are the peaking-factor formalism, the thermal-conduction model, and the virtual-source formalism. The formation of the molecular beam from the expansion and condensation phenomena occurring in the expanding gas are discussed. The molecular beam machine used in the measurements is described and special attention is given to the cryopumps used in the supersonic sources as well as to the time-of-flight analysis of the molecular beam velocity distributions. Finally, the processing of experimental data is discussed, particularly the least-squares determination of best-fit representations of the measurements.

  16. Origami structures for tunable thermal expansion

    Boatti, Elisa; Bertoldi, Katia

    Materials with engineered thermal expansion, capable of achieving targeted and extreme area/volume changes in response to variations in temperature, are important for a number of aerospace, optical, energy, and microelectronic applications. While most of the proposed structures with tunable coefficient of thermal expansion consist of bi-material 2D or 3D lattices, here we propose a periodic metastructure based on a bilayer Miura-Ori origami fold. We combine experiments and simulations to demonstrate that by tuning the geometrical and mechanical parameters an extremely broad range of thermal expansion coefficients can be obtained, spanning both negative and positive values. Additionally, the thermal properties along different directions can be adjusted independently. Differently from all previously reported systems, the proposed structure is non-porous.

    2016-07-12

    This paper develops a method to compute any bosonic conformal block as a series expansion in the optimal radial coordinate introduced by Hogervorst and Rychkov. The method reduces to the known result when the external operators are all the same scalar operator, but it allows to compute conformal blocks for external operators with spin. Moreover, we explain how to write closed form recursion relations for the coefficients of the expansions. We study three examples of four point functions in detail: one vector and three scalars; two vectors and two scalars; two spin 2 tensors and two scalars. Finally, for the case of two external vectors, we also provide a more efficient way to generate the series expansion using the analytic structure of the blocks as a function of the scaling dimension of the exchanged operator.

    The thermal expansion coefficient of technologically relevant multicomponent cubic nitride alloys are predicted using the Debye model with ab initio elastic constants calculated at 0 K and an isotropic approximation for the Grüneisen parameter. Our method is benchmarked against measured thermal expansion of TiN and Ti(1-x)Al x N as well as against results of molecular dynamics simulations. We show that the thermal expansion coefficients of Ti(1-x-y)X y Al x N (X  =  Zr, Hf, Nb, V, Ta) solid solutions monotonously increase with the amount of alloying element X at all temperatures except for Zr and Hf, for which they instead decrease for y≳ 0.5 .

    This article deals with a nonrelativistic quantum mechanical study of a dynamical system which generalizes the isotropic harmonic oscillator system in three dimensions. The Schroedinger equation for this generalized oscillator system is separable in spherical, cylindrical, and spheroidal (prolate and oblate) coordinates. The quantum mechanical spectrum of this system is worked out in some details. The problem of interbasis expansions of the wave functions is completely solved. The coefficients for the expansion of the cylindrical basis in terms of the spherical basis, and vice-versa, are found to be analytic continuations (to real values of their arguments) of Clebsch-Gordan coefficients for the group SU(2). The interbasis expansion coefficients for the prolate and oblate spheroidal bases in terms of the spherical or the cylindrical bases are shown to satisfy three-term recursion relations. Finally, a connection between the generalized oscillator system (projected on the z-line) and the Morse system (in one dimension) are discussed. 41 refs.,.

    2017-10-01

    A definition of the Grüneisen parameters for anisotropic materials is derived based on the response of phonon frequencies to uniaxial stress perturbations. This Grüneisen model relates the thermal expansion in a given direction (αi i) to one element of the elastic compliance tensor, which corresponds to the Young's modulus in that direction (Yi i). The model is tested through ab initio prediction of thermal expansion in zinc, graphite, and calcite using density functional perturbation theory, indicating that it could lead to increased accuracy for structurally complex systems. The direct dependence of αi i on Yi i suggests that materials which are flexible along their principal axes but rigid in other directions will generally display both positive and negative thermal expansion.
