    2010-10-01

    This essay discusses research on incentive-based interventions to promote healthy behavior change, contingency management (CM) and conditional cash transfers (CCT). The overarching point of the essay is that CM and CCT are often treated as distinct areas of inquiry when at their core they represent a common approach. Some potential bi-directional benefits of recognizing this commonality are discussed. Distinct intellectual traditions probably account for the separate paths of CM and CCT to date, with the former being rooted in behavioral psychology and the latter in microeconomics. It is concluded that the emerging field of behavioral economics, which is informed by and integrates principles of each of those disciplines, may provide the proper conceptual framework for integrating CM and CCT.

    Full Text Available This paper assesses whether eligibility for conditional cash transfer programs has been manipulated, as well as the impact of this phenomenon on time allocation within households. To perform this analysis, we use data from the 2006 PNAD (Brazilian national household survey and investigate the eligibility manipulation for the Bolsa Família (Family Stipend program during this time period. The program assists families with a monthly per capita income of around R$120.00 (US$60.00. By applying the tests developed by McCrary (2008, we find suggestive evidence that individuals manipulate their income by voluntarily reducing their labor supply in order to become eligible to the program. Moreover, the reduction in labor supply is greater among women, especially single or divorced mothers. This evidence raises some concern about the unintended consequences related to the eligibility criteria utilized by Bolsa Família, as well as the program's impact on individuals living in extreme poverty.

    To evaluate the impact of the Brazilian cash transfer programme (Bolsa Família Programme, BFP) on tuberculosis (TB) incidence in Brazil from 2004 to 2012. We studied tuberculosis surveillance data using a combination of an ecological multiple-group and time-trend design covering 2458 Brazilian municipalities. The main independent variable was BFP coverage and the outcome was the TB incidence rate. All study variables were obtained from national databases. We used fixed-effects negative binomial models for panel data adjusted for selected covariates and a variable representing time. After controlling for covariates, TB incidence rates were significantly reduced in municipalities with high BFP coverage compared with those with low and intermediate coverage (in a model with a time variable incidence rate ratio = 0.96, 95%CI 0.93-0.99). This was the first evidence of a statistically significant association between the increase in cash transfer programme coverage and a reduction in TB incidence rate. Our findings provide support for social protection interventions for tackling TB worldwide.

    Conditional Cash Transfer (CCT) schemes have shown largely favorable changes in the health seeking behavior. This evaluation study assesses the process and performance of an Additional Cash Incentive (ACI) scheme within an ongoing CCT scheme in India, and document lessons. A controlled before and during design study was conducted in Madhya Pradesh state of India, from August 2007 to March 2008, with increased in institutional deliveries as a primary outcome. In depth interviews, focus group discussions and household surveys were done for data collection. Lack of awareness about ACI scheme amongst general population and beneficiaries, cumbersome cash disbursement procedure, intricate eligibility criteria, extensive paper work, and insufficient focus on community involvement were the major implementation challenges. There were anecdotal reports of political interference and possible scope for corruption. At the end of implementation period, overall rate of institutional deliveries had increased in both target and control populations; however, the differences were not statistically significant. No cause and effect association could be proven by this study. Poor planning and coordination, and lack of public awareness about the scheme resulted in low utilization. Thus, proper IEC and training, detailed implementation plan, orientation training for implementer, sufficient budgetary allocation, and community participation should be an integral part for successful implementation of any such scheme. The lesson learned this evaluation study may be useful in any developing country setting and may be utilized for planning and implementation of any ACI scheme in future.

    2015-12-01

    Full Text Available This paper analyses the role of conditional cash transfers (CCT in improving social indicators during the past decade in Brazil and Peru. Barely two decades after the appearance of the first programmes, CCTs – cash transfers to families living in poverty or extreme poverty conditioned to school attendance and compulsory medical visits for children – are now one of the main policy tools in the fight against poverty in dozens of developing countries. More specifically, this paper examines the link between the CCT programme in each of these two countries – the giant Bolsa Familia in Brazil, the pioneer and largest program of this type in the world, and Juntos in Peru, smaller in terms of size and relevance, but practically identical in its design – and the evolution of social indicators relative to poverty, education and health.

    Full Text Available In the developing world, having access to a toilet does not necessarily imply use: infrequent or non-use limits the desired health outcomes of improved sanitation. We examine the sanitation situation in a rural part of South Africa where recipients of novel, waterless “urine-diverting dry toilets” are not regularly using them. In order to determine if small, conditional cash transfers (CCT could motivate families to use their toilets more, we paid for urine via different incentive-based interventions: two were based on volumetric pricing and the third was a flat-rate payment (irrespective of volume. A flat-rate payment (approx. €1 resulted in the highest rates of regular (weekly participation at 59%. The low volumetric payment (approx. €0.05/L led to regular participation rates of only 12% and no increase in toilet use. The high volumetric payment (approx. €0.1/L resulted in lower rates of regular participation (35%, but increased the average urine production per household per day by 74%. As a first example of conditional cash transfers being used in the sanitation sector, we show that they are an accepted and effective tool for increasing toilet use, while putting small cash payments in the hands of poor, largely unemployed populations in rural South Africa.

  15. Can Social Protection Weaken Clientelism? Considering Conditional Cash Transfers as Political Reform in the Philippines

    Directory of Open Access Journals (Sweden)

    Arun Ranga Swamy

    2016-01-01

    Full Text Available Since poverty is often believed to be a root cause of clientelism, government policies to reduce poverty should also help to reduce clientelism. However, scholars studying clientelism are more likely to view social policy as a potential resource for clientelist politicians. This article examines this paradox in the Philippine context by offering a general framework to identify when social welfare policies are likely to reduce clientelism, and by applying this framework to the Philippines, focusing on the Pantawid Pamilyang Pilipino conditional cash transfer programme, or Pantawid. I argue that the policies that are most likely to undercut clientelism are universal social protection policies that provide poor families with security, although these are the least acceptable to middle-class taxpayers. This is exemplified by the Philippines, which has tended to introduce social policies that increase the scope for clientelism by making discretionary allocation more likely, rather than policies that offer income security to the poor. The Pantawid programme attempts to overcome these problems by introducing a centralised targeting mechanism to identify beneficiaries and by guaranteeing the benefit to all eligible families, but like all conditional cash transfer programs falls short of guaranteed and universal social protection.

    2009-01-01

    Conditional cash transfers are becoming the standard approach to reducing poverty levels; the Brazilian Bolsa Familia Program, in particular, is the largest program of this kind, and the evaluation of its impact allows for drawing some interesting conclusions, which may apply to other countries. In this paper, the lack of positive results in terms of both health status and modification of unhealthy habits is underlined. Among different causes, which are discussed here, the existence of barriers on the supply side appears as the most important limitation for obtaining better results. The positive impact of this program on both education and poverty reduction however, allows for predicting improvements in health status in the long run.

    2015-07-01

    Full Text Available This paper evaluates the impact of Avancemos, a conditional cash transfer program in Costa Rica. Specifically, this paper measures the impact on student desertion for the first year of the program using a panel created with the Household Surveys for Multiple Purposes for the years 2006 and 2007, elaborated by the National Institute of Statistics and Census. Using econometric tools and quasi-experimental methodologies such as Propensity Score Matching and difference-in-differences, we find a positive impact associated to the program for desertion and reinsertion. Specifically, for between 10 and 16 percent of the students who did not leave high school, it was only due to Avancemos, meaning that without the program they would have abandoned their studies. This is why we can conclude that Avancemos had a positive impact according to its planned objectives of preventing dropouts and ensuring their reinsertion.

    Violence against women is a major health and human rights problem yet there is little rigorous evidence as to how to reduce it. We take advantage of the randomized roll-out of Ecuador's cash transfer program to mothers to investigate how an exogenous increase in a woman's income affects domestic violence. We find that the effect of a cash transfer depends on a woman's education and on her education relative to her partner's. Our results show that for women with greater than primary school education a cash transfer significantly decreases psychological violence from her partner. For women with primary school education or less, however, the effect of a cash transfer depends on her education relative to her partner's. Specifically, the cash transfer significantly increases emotional violence in households where the woman's education is equal to or more than her partner's. Copyright © 2012 Elsevier B.V.

    2011-01-01

    Abstract Objective To examine the association between Brazil’s Bolsa Familia programme (BFP), which is the world's largest conditional cash transfer programme, and the anthropometric indicators of nutritional status in children. Methods Using the opportunity provided by vaccination campaigns, the Brazilian government promotes Health and Nutrition Days to estimate the prevalence of anthropometric deficits in children. Data collected in 2005–2006 for 22 375 impoverished children under 5 years of age were employed to estimate nutritional outcomes among recipients of Bolsa Família. All variables under study, namely child birth weight, lack of birth certificate, educational level and gender of family head, access to piped water and electricity, height for age, weight for age and weight for height, were converted into binary variables for regression analysis. Findings Children from families exposed to the BFP were 26% more likely to have normal height for age than those from non-exposed families; this difference also applied to weight for age. No statistically significant deficit in weight for height was found. Stratification by age group revealed 19% and 41% higher odds of having normal height for age at 12–35 and 36–59 months of age, respectively, in children receiving Bolsa Familia, and no difference at 0–11 months of age. Conclusion The BFP can lead to better nutritional outcomes in children 12 to 59 months of age. Longitudinal studies are needed to confirm these findings. PMID:21734763

    Full Text Available ABSTRACT Objective To 1 describe the benefits, conditions, coverage, funding, goals, governance, and structure of well-established conditional cash transfer programs (CCTs in Latin America and 2 identify their health and nutritional impacts among children under 5 years old. Methods A realist review was conducted. CCTs were included if they met the following inclusion criteria: 1 current national-level program; 2 coverage of at least 50% of the target population; 3 continuous operation at scale for 10+ years; 4 clear description of structure, funding sources, and governance; 5 both health/nutrition- and education-related conditions for participation; and 6 available impact evaluation studies with health, development, and/or nutrition indicators among children under 5 years old. Three CCTs (one each in Brazil, Colombia, and Mexico met the criteria. Results There was consistent evidence that the three CCTs selected for review had positive impacts on child health and nutrition outcomes in their respective countries. In all three countries, the programs were scaled up and positive impacts were documented relatively quickly. All three programs had strong political support and clear and transparent governance structures, including accountability and social participation mechanisms, which might explain their success and sustainability. Conclusions CCTs in Latin America have had a positive impact on child health and nutrition outcomes among the poorest families. A key challenge for the future is to reform these programs to help families move out of not only extreme poverty but all poverty in order to lead healthy and productive lives, as called for in the post-2105 Sustainable Development Goals.

    2017-07-01

    In some countries, conditional cash transfer (CCT) programmes show an impact on maternal and child health. Juntos, the CCT programme in Peru, has been evaluated several times operationally, but seldom for maternal and child health outcomes. The objective of this study is to evaluate the impact of Juntos on children under 6 years, pregnant women and mothers of children under 17 years. Outcomes evaluated included (1) anaemia in women and children; (2) acute malnutrition in children; (3) post-partum complications in mothers; and (4) underweight and overweight in mothers. We identified Juntos eligible respondents from the Demographic and Health Surveys of Peru for years 2007 to 2013. Propensity score matching was used to identify comparable treatment and control groups, including eligible respondents enrolled in Juntos vs. those not enrolled in Juntos (individual-level analysis), as well as eligible respondents living in Juntos districts vs. those not residing in Juntos districts (district-level analysis). We then used generalized linear models to estimate prevalence ratios. Individual level analysis showed that Juntos reduced underweight in women (PR:0.39, 95%CI:0.18 - 0.85) and anaemia in children (PR:0.93, 95%CI:0.86 - 1.00). In the district level analysis, the programme was associated with a reduction of overweight in women (PR:0.94, 95%CI:0.90 - 0.98) and acute malnutrition in children (PR:0.49, 95%CI:0.32 - 0.73), but an increase in the prevalence of anaemia in children (PR:1.09, 95%CI:1.01 - 1.17). We found that Juntos had an effect on maternal and child health indicators, but further studies are required to overcome some limitations encountered here. © 2016 John Wiley & Sons Ltd.

  7. Political Competition and the Diffusion of Conditional Cash Transfers in Brazil

    2012-12-01

    Full Text Available What factors determine the diffusion of social policies? This article exam - ines the launching of conditional cash transfer programs by Brazilian munici - palities to explore this problem. The literature of political science asserts that such programs have been widely implemented because they correspond to an al - ternative policy strategy adopted by governments facing opposition to implement universal public policies. So, political competition would be at the root of CCT launching. This article presents an alternative explanation. From 1995 to 2001, local governments created or emulated the Bolsa Escola Program (BEP in all regions of the country. Such a path continued after the lauching of the national Bolsa Escola by the federal government. Why did some local governments decide to adopt the national BEP and others did not? To answer these questions, the research tests the influence of structural, internal and external variables on the dissemination of CCT programs. Two main hypotheses are tested. The first as - serts that local political competition is positive for policy diffusion. The second hypothesis claims that party alignment between the municipal and federal levels increases the likelihood of municipalities adopting the federal BEP. The research uses Event History Analysis to test statistically the impact of political incentives on policy diffusion among São Paulo State’s municipalities. Two types of policy diffusion are examined: horizontal and vertical. The findings confirm that polit - ical competition influences the horizontal diffusion among municipalities. Unex - pectedly, vertical diffusion does not occur because of party alignment or political competition. Rather, levels of socioeconomic development drive policy emulation.

  8. Can conditional cash transfers improve the uptake of nutrition interventions and household food security? Evidence from Odisha's Mamata scheme.

    Directory of Open Access Journals (Sweden)

    Kalyani Raghunathan

    Full Text Available There is considerable global evidence on the effectiveness of cash transfers in improving health and nutrition outcomes; however, the evidence from South Asia, particularly India, is limited. In the context of India where more than a third of children are undernourished, and where there is considerable under-utilization of health and nutrition interventions, it is opportune to investigate the impact of cash transfer programs on the use of interventions. We study one conditional cash transfer program, Mamata scheme, implemented in the state of Odisha, in India that targeted pregnant and lactating women. Using survey data on 1161 households from three districts in the state of Odisha, we examine the effect of the scheme on eight outcomes: 1 pregnancy registration; 2 receipt of antenatal services; 3 receipt of iron and folic acid (IFA tablets; 4 exposure to counseling during pregnancy; 5 exposure to postnatal counseling; 6 exclusive breastfeeding; 7 full immunization; and 8 household food security. We conduct regression analyses and correct for endogeneity using nearest-neighbor matching and inverse-probability weighting models. We find that the receipt of payments from the Mamata scheme is associated with a 5 percentage point (pp increase in the likelihood of receiving antenatal services, a 10 pp increase in the likelihood of receiving IFA tablets, and a decline of 0.84 on the Household Food Insecurity Access Scale. These results provide the first quantitative estimates of effects associated with the Mamata scheme, which can inform the design of government policies related to conditional cash transfers.

    Full Text Available Context: Satara district of western Maharashtra is in late expanding phase of demographic cycle. Postponement of first pregnancy with the use of reversible contraceptives is the need of the hour. Since 2007, Satara district is implementing a conditional cash transfer scheme second honeymoon package (SHP. Objectives: The objectives of this study are: (1 To find out the effect of conditional cash transfer on choice and utilization of contraceptives among participants of SHP. (2 To identify various barriers to the use of contraceptives. Materials and Methods: This was an evaluation study of a community based interventional program. Cases were the participants of SHP program while the controls were the couples residing in the same village as that of participants and married in the same year. Enquiries were made about their knowledge of contraceptives, reasons of postponement, choice of contraceptives, problems faced while using them, perceived benefits of participation, reasons for non-participation and non-use of contraceptives, etc. Results: This study has found out that 24.8% controls and 57.6% participant couples were having knowledge of contraception before their marriage. Amongst the participants of the scheme and controls, male condom was the most popular method used by 80.8% participants, followed by oral pills by 9.22% couples. Contraception prevalence rate among control couples was 17.6%, while that in participants was 91.8%. Resistance from family members, side-effects and failure of contraceptives were some of the barriers to their use. Conclusions: Conditional cash transfer has encouraged the use of contraceptives in acceptors of SHP. By participating in SHP and postponing first pregnancy 15.8% could complete their education, job/career betterment achieved by 16.4% and 19.3% adored marital pleasure.

    Full Text Available This article examines whether the state, through conditional cash transfer programs (CCT, can reduce the poverty and extremely poverty in societies marred by high levels of income concentration. We focus on one of the most unequal countries in the globe, Brazil, and analyze the extent to which this country's CCT program - Bolsa Família (BF, Family Grant program - is able to improve the life chances of extremely poor beneficiaries, through the three major goals of PBF: First, to immediately end hunger; second, to create basic social rights related to healthcare and education; finally, considering also complementary policies, to integrate adults into the job market. The analysis relies on a quantitative survey with 4,000 beneficiaries and a qualitative survey comprised of in-depth interviews with 38 program's participants from all the regions of the country in 2008, it means that this study is about the five first years of the PBF. In order to answer the research questions, we ran four probit analyses related: a the determinants of the realization of prenatal care; b the determinants of food security among BF beneficiaries, c the determinants that adult BF recipients will return to school, d the determinants that a BF beneficiary will obtain a job. Important results from the study are: First, those who before their participation on PBF were at the margins have now been able to access healthcare services on a more regular basis. Thus, the women at the margins who were systematically excluded - black women, poorly educated and from the North - now, after their participation in the CCT program, have more access to prenatal care and can now count with more availability of public healthcare network. Second, before entering the Bolsa Família program, 50.3% of the participants faced severe food insecurity. This number went down to 36.8% in very five years. Men are more likely than women; non-blacks more likely than blacks; and South and Centre

    Conditional cash transfers (CCT) provide monetary transfers to households on the condition that they comply with some pre-defined requirements. CCT programmes have been justified on the grounds that demand-side subsidies are necessary to address inequities in access to health and social services for poor people. In the past decade they have become increasingly popular, particularly in middle income countries in Latin America. To assess the effectiveness of CCT in improving access to care and health outcomes, in particular for poorer populations in low and middle income countries. We searched a wide range of international databases, including the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE, in addition to development studies and economic databases. We also searched the websites and online resources of numerous international agencies, organisations and universities to find relevant grey literature. The original searches were conducted between November 2005 and April 2006. An updated search in MEDLINE was carried out in May 2009. CCT were defined as monetary transfers made to households on the condition that they comply with some pre-determined requirements in relation to health care. Studies had to include an objective measure of at least one of the following outcomes: health care utilisation, health expenditure, health outcomes or equity outcomes. Eligible study designs were: randomised controlled trial, interrupted time series analysis, or controlled before-after study of the impact of health financing policies following criteria used by the Cochrane Effective Practice and Organisation of Care Group. We performed qualitative analysis of the evidence. We included ten papers reporting results from six intervention studies. Overall, design quality and analysis limited the risks of bias. Several CCT programmes provided strong evidence of a positive impact on the use of health services, nutritional status and health outcomes

    Cash transfer programs seek to alter structural determinants of HIV risk such as poverty and gender inequality. We sought to explore the feasibility and potential effectiveness of a cash transfer intervention for young women as part of combination HIV prevention in Iringa, Tanzania. Qualitative, in-depth interviews were conducted with 116 stakeholders and residents from the region, including key informants, service delivery users, and members of key populations. Most respondents felt a cash transfer program would assist young women in Iringa to have more control over sexual decision-making and reduce poverty-driven transactional sex. Respondents were divided on who should receive funds: young women themselves, their parents/guardians, or community leaders. Cash amounts and suggested target groups varied, and several respondents suggested providing microcredit or small business capital instead of cash. Potential concerns included jealousy, dependency, and corruption. However, most respondents felt that some intervention was needed to address underlying poverty driving some sexual risk behavior. A cash transfer program could fill this role, ultimately reducing HIV, sexually transmitted infections, and unintended pregnancies. As increased attention is given to economic and structural interventions for HIV prevention, local input and knowledge should be considered in a program design.

    Cash-transfer programmes can improve the wellbeing of vulnerable children, but few studies have rigorously assessed their effectiveness in sub-Saharan Africa. We investigated the effects of unconditional cash transfers (UCTs) and conditional cash transfers (CCTs) on birth registration, vaccination uptake, and school attendance in children in Zimbabwe. We did a matched, cluster-randomised controlled trial in ten sites in Manicaland, Zimbabwe. We divided each study site into three clusters. After a baseline survey between July, and September, 2009, clusters in each site were randomly assigned to UCT, CCT, or control, by drawing of lots from a hat. Eligible households contained children younger than 18 years and satisfied at least one other criteria: head of household was younger than 18 years; household cared for at least one orphan younger than 18 years, a disabled person, or an individual who was chronically ill; or household was in poorest wealth quintile. Between January, 2010, and January, 2011, households in UCT clusters collected payments every 2 months. Households in CCT clusters could receive the same amount but were monitored for compliance with several conditions related to child wellbeing. Eligible households in all clusters, including control clusters, had access to parenting skills classes and received maize seed and fertiliser in December, 2009, and August, 2010. Households and individuals delivering the intervention were not masked, but data analysts were. The primary endpoints were proportion of children younger than 5 years with a birth certificate, proportion younger than 5 years with up-to-date vaccinations, and proportion aged 6-12 years attending school at least 80% of the time. This trial is registered with ClinicalTrials.gov, number NCT00966849. 1199 eligible households were allocated to the control group, 1525 to the UCT group, and 1319 to the CCT group. Compared with control clusters, the proportion of children aged 0-4 years with birth

  16. Effect of the conditional cash transfer program Oportunidades on vaccination coverage in older Mexican people

    Science.gov (United States)

    2013-01-01

    Background Immunization is one of the most effective ways of preventing illness, disability and death from infectious diseases for older people. However, worldwide immunization rates are still low, particularly for the most vulnerable groups within the elderly population. The objective of this study was to estimate the effect of the Oportunidades -an incentive-based poverty alleviation program- on vaccination coverage for poor and rural older people in Mexico. Methods Cross-sectional study, based on 2007 Oportunidades Evaluation Survey, conducted in low-income households from 741 rural communities (localities with <2,500 inhabitants) of 13 Mexican states. Vaccination coverage was defined according to three individual vaccines: tetanus, influenza and pneumococcal, and for complete vaccination schedule. Propensity score matching and linear probability model were used in order to estimate the Oportunidades effect. Results 12,146 older people were interviewed, and 7% presented cognitive impairment. Among remaining, 4,628 were matched. Low coverage rates were observed for the vaccines analyzed. For Oportunidades and non-Oportunidades populations were 46% and 41% for influenza, 52% and 45% for pneumococcal disease, and 79% and 71% for tetanus, respectively. Oportunidades effect was significant in increasing the proportion of older people vaccinated: for complete schedule 5.5% (CI95% 2.8-8.3), for influenza 6.9% (CI95% 3.8-9.6), for pneumococcal 7.2% (CI95% 4.3-10.2), and for tetanus 6.6% (CI95% 4.1-9.2). Conclusions The results of this study extend the evidence on the effect that conditional transfer programs exert on health indicators. In particular, Oportunidades increased vaccination rates in the population of older people. There is a need to continue raising vaccination rates, however, particularly for the most vulnerable older people. PMID:23835202

    The review aimed to assess the effectiveness of conditional cash transfers (CCTs) in improving child health in low- and middle-income countries. Seven electronic databases were searched for papers: MEDLINE, EMBASE, PubMed, PsychINFO, BIOSIS Previews, Academic Search Complete, and CSA Sociological Abstracts. The included studies comprised of randomised controlled trials and controlled before-and-after studies evaluating the impact of CCTs on child health. Due to the substantial heterogeneity of the studies, a narrative synthesis was conducted on the extracted data. Sixteen studies predominantly from Latin American countries met the inclusion criteria. The outcomes reported by the studies in relation to CCTs' effectiveness in improving child health were reduction in morbidity risk, improvement in nutritional outcomes, health services utilisation, and immunisation coverage. The review suggests that to a large extent, CCTs are effective in improving child health by addressing child health determinants such as access to health care, child and maternal nutrition, morbidity risk, immunisation coverage, and household poverty in developing countries particularly middle-income countries. Of importance to both policy and practice, it appears that CCTs require effective functioning of health care systems to effectively promote child health.

  18. Janani Suraksha Yojana: the conditional cash transfer scheme to reduce maternal mortality in India - a need for reassessment.

    2012-01-01

    Alongside endorsing Millennium Development Goal 5 in 2000, India launched its National Population Policy in 2000 and the National Health Policy in 2002. However, these have failed thus far to reduce the maternal mortality ratio (MMR) by the targeted 5.5% per annum. Under the banner of the National Rural Health Mission, the Government of India launched a national conditional cash transfer (CCT) scheme in 2005 called Janani Suraksha Yojana (JSY), aimed to encourage women to give birth in health facilities which, in turn, should reduce maternal deaths. Poor prenatal care in general, and postnatal care in particular, could be considered the causes of the high number of maternal deaths in India (the highest in the world). Undoubtedly, institutional delivery in India has increased and MMR has reduced over time as a result of socioeconomic development coupled with advancement in health care including improved women's education, awareness and availability of health services. However, in the light of its performance, we argue that the JSY scheme was not well enough designed to be considered as an effective pathway to reduce MMR. We propose that the service-based CCT is not the solution to avoid/reduce maternal deaths and that policy-makers and programme managers should reconsider the 'package' of continuum of care and maternal health services to ensure that they start from adolescence and the pre-pregnancy period, and extend to delivery, postnatal and continued maternal health care.

  19. The impact of a conditional cash transfer program on the utilization of non-targeted services: Evidence from Afghanistan.

    While existing research suggests that health-related conditional cash transfer (CCT) programs have positive impacts on the utilization of CCT-targeted health services, little is known as to whether they also influence the utilization of non-targeted health services-defined as general health services for which program participants are not financially motivated. Based on a sample of 6649 households in a CCT program that took place in May 2009-June 2011 in Afghanistan, we evaluate the impact of the receipt of CCTs on the utilization of non-targeted health services both by women, who were direct beneficiaries of the program, and by members of their households. We estimate the outcomes of interest through four probit models, accounting for potential endogeneity of the CCT receipt and dealing with lack of credible exclusion restrictions in different ways. In comparison with the control group, the receipt of CCTs is found to be associated with an increase in the probability of utilizing non-targeted services among household members across regression models. The results are mixed, with regard to the utilization by women, suggesting that there exist non-economic barriers to health care, unique to women, that are not captured by the data. The results confirm the importance of accounting for direct as well as indirect effects in policy evaluation and suggest that future studies investigate more deeply the role of community health workers in removing non-economic barriers for Afghan women and the possibility of introducing an incentive structure to motivate them to contribute more actively to population health in Afghanistan.

    2018-05-01

    Full Text Available Conditional Cash Transfer Programs (CCT have been implemented in México and Latin America since the late 1990’s. This type of program focuses on providing social government services by way of direct cash transfers to poor families that are often conditioned to the use of public education and health services. Despite the apparent short-term success of these CCT programs in the Latin American context, there still is much debate about whether CCT programs are effective in alleviating poverty. This paper analyzes the effectiveness of conditional cash transfer programs as a long-term incentive in the use of public services—health and education—among beneficiary families of PROSPERA-Oportunidades in Mexico. The Average Effect of Treatment on the Treated (ATT for the time period 2002–2012 is estimated based on data from the Mexican Family Life Survey (MxFLS using Propensity Score Matching (PSM. The results show that the program’s impact on the use of preventive health and education services by poor families cannot be sustained in the long-term, which puts in doubt the effectiveness of this social protection intervention program in combating poverty in Mexico.

    2013-08-23

    Cash payments to vulnerable households and/or individuals have increasingly garnered attention as a means to reduce poverty, improve health and achieve other development-related outcomes. Recent evidence from Malawi and Tanzania suggests that cash transfers can impact HIV-related behaviours and outcomes and, therefore, could serve as an important addition to HIV prevention efforts. This article reviews the current evidence on cash transfers for HIV prevention and suggests unresolved questions for further research. Gaps include (1) understanding more about the mechanisms and pathways through which cash transfers affect HIV-related outcomes; (2) addressing key operational questions, including the potential feasibility and the costs and benefits of different models of transfers and conditionality; and (3) evaluating and enhancing the wider impacts of cash transfers on health and development. Ongoing and future studies should build on current findings to unpack unresolved questions and to collect additional evidence on the multiple impacts of transfers in different settings. Furthermore, in order to address questions on sustainability, cash transfer programmes need to be integrated with other sectors and programmes that address structural factors such as education and programming to promote gender equality and address HIV.

    Demand-side strategies could contribute to achieving high and timely vaccine coverage in rural Africa, but require platforms to deliver either messages or conditional cash transfers (CCTs). We studied the feasibility of using short message services (SMS) reminders and mobile phone-based conditional cash transfers (CCTs) to reach parents in rural Western Kenya. In a Health and Demographic Surveillance System (HDSS), mothers with children aged 0-3 weeks old were approached to determine who had access to a mobile phone. SMS reminders were sent three days prior to and on the scheduled day of immunization for 1st (age 6 weeks) and 2nd doses (age 10 weeks) of DTP-HepB-Hib (Pentavalent) vaccine, using open-source Rapid SMS software. Approximately $2.00 USD was sent as cash using mPESA, a mobile money transfer platform (2/3 of mothers), or airtime (1/3 of mothers) via phone if the child was vaccinated within 4 weeks of the scheduled date. Follow-up surveys were done when children reached 14 weeks of age. We approached 77 mothers; 72 were enrolled into the study (26% owned a phone and 74% used someone else's). Of the 63 children with known vaccination status at 14 weeks of age, 57 (90%) received pentavalent1 and 54 (86%) received pentavalent2 within 4 weeks of their scheduled date. Of the 61 mothers with follow-up surveys administered at 14 weeks of age, 55 (90%) reported having received SMS reminders. Of the 54 women who reported having received SMS reminders and answered the CCT questions on the survey, 45 (83%) reported receiving their CCT. Most (89%) of mothers in the mPESA group obtained their cash within 3 days of being sent their credit via mobile phone. All mothers stated they preferred CCTs as cash via mobile phone rather than airtime. Of the 9 participants who did not vaccinate their children at the designated clinic 2(22%) cited refusals by husbands to participate in the study. The data show that in rural Western Kenya mobile phone-based strategies are a

    In light of the continuing rise in food prices during and after the 2008 world food crisis, whether food and cash transfers are equally effective in improving food security and diet quality is debatable. To compare the effects of conditional food and cash transfers of the Ethiopian Productive Safety Net Program (PSNP) on household food security and dietary diversity. Data on household dietary diversity, child anthropometry, food security, and preference of transfer modalities (food, cash, or mixed) were generated from a cross-sectional survey of 195 PSNP beneficiary households (67 receiving food and 128 receiving cash) in Hawella Tulla District, Sidama, southern Ethiopia. Most beneficiaries (96%) reported food shortages, and 47% reported food shortages that exceeded 3 months. Households receiving cash had better household dietary diversity scores (p = .02) and higher consumption of oils and fats (p = .003) and vitamin A-rich foods (p = .002). Compared with households receiving food, households receiving cash were more affected by increases in food prices that forced them to reduce their number of daily meals (p diversity than households receiving food, a result suggesting that cash transfers may be more effective. However, the continuing rise infood prices may offset these benefits unless cash transfers are index-linked to food price fluctuations.

    India accounts for 19% of global maternal deaths, three-quarters of which come from nine states. In 2005, India launched a conditional cash transfer (CCT) programme, Janani Suraksha Yojana (JSY), to reduce maternal mortality ratio (MMR) through promotion of institutional births. JSY is the largest CCT in the world. In the nine states with relatively lower socioeconomic levels, JSY provides a cash incentive to all women on birthing in health institution. The cash incentive is intended to reduce financial barriers to accessing institutional care for delivery. Increased institutional births are expected to reduce MMR. Thus, JSY is expected to (a) increase institutional births and (b) reduce MMR in states with high proportions of institutional births. We examine the association between (a) service uptake, i.e., institutional birth proportions and (b) health outcome, i.e., MMR. Data from Sample Registration Survey of India were analysed to describe trends in proportion of institutional births before (2005) and during (2006-2010) the implementation of the JSY. Data from Annual Health Survey (2010-2011) for all 284 districts in above- mentioned nine states were analysed to assess relationship between MMR and institutional births. Proportion of institutional births increased from a pre-programme average of 20% to 49% in 5 years (phigh institutional birth proportions that JSY has achieved are of themselves inadequate to reduce MMR. Other factors including improved quality of care at institutions are required for intended effect.

    We investigated (1) how household wealth affected the relationship between conditional cash transfers (CCT) and unconditional cash transfers (UCT) and school attendance, (2) whether CCT and UCT affected educational outcomes (repeating a year of school), (3) if baseline school attendance and transfer conditions affected how much of the transfers participants spent on education and (4) if CCT or UCT reduced child labour in recipient households. Data were analysed from a cluster-randomized controlled trial of CCT and UCT in 4043 households from 2009 to 2010. Recipient households received $18 dollars per month plus $4 per child. CCT were conditioned on above 80% school attendance, a full vaccination record and a birth certificate. In the poorest quintile, the odds ratio of above 80% school attendance at follow-up for those with below 80% school attendance at baseline was 1.06 (p = .67) for UCT vs. CCT. UCT recipients reported spending slightly more (46.1% (45.4-46.7)) of the transfer on school expenses than did CCT recipients (44.8% (44.1-45.5)). Amongst those with baseline school attendance of below 80%, there was no statistically significant difference between CCT and UCT participants in the proportion of the transfer spent on school expenses (p = .63). Amongst those with above 80% baseline school attendance, CCT participants spent 3.5% less (p = .001) on school expenses than UCT participants. UCT participants were no less likely than those in the control group to repeat a grade of school. CCT participants had .69 (.60-.79) lower odds vs. control of repeating the previous school grade. Children in CCT recipient households spent an average of .31 fewer hours in paid work than those in the control group (p control arm (p = .06).

    We designed and evaluated for feasibility an intervention-Yo Puedo-that addresses social network influences and socioeconomic opportunities in a neighborhood with substantial gang exposure and early childbearing. Yo Puedo combined conditional cash transfers for completion of educational and reproductive health wellness goals with life skills sessions, and targeted youth 16-21 years of age and same-aged members of their social network. We conducted a two-arm study with social networks randomized to the intervention or a standard services control arm. We evaluated intervention uptake, adherence, and safety; and assessed evidence of effects on behavioral outcomes associated with unintended pregnancy and sexually transmitted infection risk. A total of 72 social networks composed of 162 youth enrolled, with 92% retention over 6 months. Seventy-two percent of youth randomized to the intervention participated in intervention activities: 53% received at least one conditional cash transfer payment and 66% came to at least one life skills session. We found no evidence that cash payments financed illicit or high-risk behavior. At 6 months, compared with controls, intervention participants had a lower odds of hanging out on the street frequently (odds ratio [OR], .54; p = .10) and a lower odds of reporting that their close friends had been incarcerated (OR, .6; p = .12). They reported less regular alcohol use (OR, .54; p = .04) and a lower odds of having sex (OR, .50; p = .04). The feasibility evaluation of Yo Puedo demonstrated its promise; a larger evaluation of effects on pregnancy and sustained behavioral changes is warranted.

    Developed countries have pledged billions of dollars a year to help poor nations adapt to climate change. But how should the money be spent? For the world's poor, who are both the most vulnerable to climate change and the most in need of social protection, the best answer may be cash transfer programmes. Giving money out in this way has a strong track record in reaching the poor and helping them improve their nutrition, education and incomes — all of which are vital for building their long-term capacity to adapt to climate change. Cash transfers are also well accepted at the local level and, given the right political backing, can be implemented on a broad scale.

    2014-01-31

    Haryana was the first state in India to launch a conditional cash transfer (CCT) scheme in 1994. Initially it targeted all disadvantaged girls but was revised in 2005 to restrict it to second girl children of all groups. The benefit which accrued at girl attaining 18 years and subject to conditionalities of being fully immunized, studying till class 10 and remaining unmarried, was increased from about US$ 500 to US$ 2000. Using a mixed methods approach, we evaluated the implementation and possible impact of these two schemes. A survey was conducted among 200 randomly selected respondents of Ballabgarh Block in Haryana to assess their perceptions of girl children and related schemes. A cohort of births during this period was assembled from population database of 28 villages in this block and changes in sex ratio at birth and in immunization coverage at one year of age among boys and girls was measured. Education levels and mean age at marriage of daughters were compared with daughters-in-law from outside Haryana. In-depth interviews were conducted among district level implementers of these schemes to assess their perceptions of programs' implementation and impact. These were analyzed using a thematic approach. The perceptions of girls as a liability and poor (9% to 15%) awareness of the schemes was noted. The cohort analysis showed that while there has been an improvement in the indicators studied, these were similar to those seen among the control groups. Qualitative analysis identified a "conspiracy of silence" - an underplaying of the pervasiveness of the problem coupled with a passive implementation of the program and a clash between political culture of giving subsidies and a bureaucratic approach that imposed many conditionalities and documentary needs for availing of benefits. The apparent lack of impact on the societal mindset calls for a revision in the current approach of addressing a social issue by a purely conditional cash transfer program.

Considera que a TCR impacta os gastos com alimentação, especialmente quando há dinamismo de mercado e os investimentos com outros bens que afetam o bem- estar nutricional das famílias, incluindo a demanda por educação e cuidados com a saúde. No entanto, o impacto no estado nutricional, especialmente no crescimento infantil, não é inequívoco, pois depende de outras ações que afetam este processo, tais como a disponibilidade de serviços de saúde; educação; saneamento; os custos das famílias para acessá-los; o tempo de implementação dos programas; o valor transferido; o tamanho das famílias, além das regras intrafamiliares de alocação de recursos. De igual modo, cabe analisar o processo de implementação dos programas uma vez que podem afetar (positiva ou negativamente os valores, relações e práticas sociais que contribuem para a conformação da pobreza e da SAN.

    Full Text Available Payment systems play a significant role in our daily lives. They are an important driver of economic activities and a vital part of the banking infrastructure of any country. Several current payment systems focus on security and reliability but pay less attention to users’ needs and behaviors. For example, people may share their bankcards with friends or relatives to withdraw money for various reasons. This behavior can lead to a variety of privacy and security issues since the cardholder has to share a bankcard and other sensitive information such as a personal identification number (PIN. In addition, it is commonplace that cardholders may lose their cards, and may not be able to access their accounts due to various reasons. Furthermore, transferring money to an individual who has lost their bankcard and identification information is not a straightforward task. A user-friendly person-to-person payment system is urgently needed to perform secure and reliable transactions that benefit from current technological advancements. In this paper, we propose two secure fund transfer methods termed QuickCash Online and QuickCash Offline to transfer money from peer to peer using the existing banking infrastructure. Our methods provide a convenient way to transfer money quickly, and they do not require using bank cards or any identification card.

    Payment systems play a significant role in our daily lives. They are an important driver of economic activities and a vital part of the banking infrastructure of any country. Several current payment systems focus on security and reliability but pay less attention to users’ needs and behaviors. For example, people may share their bankcards with friends or relatives to withdraw money for various reasons. This behavior can lead to a variety of privacy and security issues since the cardholder has to share a bankcard and other sensitive information such as a personal identification number (PIN). In addition, it is commonplace that cardholders may lose their cards, and may not be able to access their accounts due to various reasons. Furthermore, transferring money to an individual who has lost their bankcard and identification information is not a straightforward task. A user-friendly person-to-person payment system is urgently needed to perform secure and reliable transactions that benefit from current technological advancements. In this paper, we propose two secure fund transfer methods termed QuickCash Online and QuickCash Offline to transfer money from peer to peer using the existing banking infrastructure. Our methods provide a convenient way to transfer money quickly, and they do not require using bank cards or any identification card. Unlike other person-to-person payment systems, the proposed methods do not require the receiving entity to have a bank account, or to perform any registration procedure.

Employing data collected at the regional level, we establish four main findings: (1 all 4Ps payment conduits present trade-offs; (2 a payment approach that uses mainstream financial infrastructure is beneficial if cost, speed and simplicity of the payment system are critical; (3 competition for 4Ps contracts for Payment Service Providers (PSPs has improved the quality of payment services and minimized costs; and (4 the efficiency of the program is greatly influenced by the commitment of the PSP to deliver the cash benefits to the recipients in a timely manner rather than by maximizing conduit branches.

    Background: It is unclear what effects a conditional cash transfer (CCT) program would have on child anthropometry, language development, or school achievement in the context of the nutrition transition experienced by many low- and middle-income countries. Objective: We estimated the association of participation in Peru’s Juntos CCT with anthropometry, language development, and school achievement among children aged 7–8 y. Methods: We used data from the Young Lives Study of a cohort born between 2001 and 2002. We estimated associations of the Juntos program with height-for-age z score (HAZ), body mass index–for–age z score (BAZ), stunting, and overweight at age 7–8 y separately for children participating in the program for ≥2 y (n = 169) and children participating for overweight (ATT: –22.0 percentage points; 95% CI: –42.5, –2.7 percentage points; P = 0.03). We observed no significant associations of Juntos participation with receptive vocabulary or grade attainment. Conclusions: CCT program participation in Peru was associated with better linear growth among boys and decreased BAZ among girls, highlighting that a large-scale poverty-alleviation intervention may influence anthropometric outcomes in the context of the nutrition transition.

    Mexico's conditional cash transfer programme, Oportunidades, was started to improve the lives of poor families through interventions in health, nutrition, and education. We investigated the effect of Oportunidades on children almost 10 years after the programme began. From April, 1998, to October, 1999, low-income communities were randomly assigned to be enrolled in Oportunidades immediately (early treatment, n=320) or 18 months later (late treatment, n=186). In 2007, when 1093 children receiving early treatment and 700 late treatment in these communities were aged 8-10 years, they were assessed for outcomes including physical growth, cognitive and language development, and socioemotional development. The primary objective was to investigate outcomes associated with an additional 18 months in the programme. We used cluster-adjusted t tests and multivariate regressions to compare effects of programme participation for height-for-age, body-mass index (BMI), and cognitive language and behavioural assessment scores in early versus late treatment groups. Early enrolment reduced behavioural problems for all children in the early versus late treatment group (mean behaviour problem score -0.09 [SD 0.97] vs 0.13 [1.03]; p=0.0024), but we identified no difference between groups for mean height-for-age Z scores (-1.12 [0.96] vs -1.14 [0.97]; p=0.88), BMI-for-age Z scores (0.14 [0.99] vs 0.17 [1.06]; p=0.58), or assessment scores for language (98.8 [13.8] vs 98.4 [14.6] p=0.90) or cognition (98.8 [12.9] vs 100.2 [13.2]; p=0.26). An additional 18 months of the programme before age 3 years for children aged 8-10 years whose mothers had no education resulted in improved child growth of about 1.5 cm assessed as height-for-age [corrected] Z score (beta 0.23 [0.023-0.44] p=0.029), independently of cash received. An additional 18 months in the Oportunidades programme has independent beneficial effects other than money, especially for women with no formal education. The money itself

    Under the National Health Mission (NHM) of India, Janani Suraksha Yojana (JSY) offers conditional cash transfer and support services to pregnant women to use institutional delivery care facilities. This study aims to understand community health workers' (ASHAs) and program officials' perceptions regarding barriers to and prospects for the uptake of facilities offered under the JSY. Fifty in-depth interviews of a purposively selected sample of ASHAs (n = 12), members of Village Health and Sanitation Committees (n = 11), and officials at different tiers of healthcare facilities (n = 27) were conducted in three Indian states. The data were analyzed thematically using ATLAS.ti software. Although the JSY has triggered considerable advancement on the Indian maternal and child health front, there are several barriers to be resolved pertaining to i) delivering quality care at health-facility; ii) linkages between home and health-facility; and iii) the community/household context. At the facility level, respondents cited an inability to treat birth complications as a barrier to JSY uptake, resulting in referrals to other (mostly private) facilities. Despite increased investment in health infrastructure under the program, shortages in emergency obstetric-care facilities, specialists and staff, essential drugs, diagnostics, and necessary equipment persisted. Weaker linkages between various vertical (standalone) elements of maternal and primary healthcare programs, and nearly uniform resource allocation to all facilities irrespective of caseloads and actual need also constrained the provision of quality healthcare. Barriers affecting the linkages between home and facility arose mainly due to the mismatch between the multiple demands and the availability of transport facilities, especially in emergency situations. Regarding community/household context, several socio-cultural issues such as resistance towards the ASHA's efforts of counselling, particularly from

    India's approach to social security stresses the provision of subsidized food and public works. Targeted, unconditional cash transfers are little used, and have been little evaluated. An evaluation of cash transfers for the elderly and widows based on national household survey data and surveys on social pension utilization in two of India's states, Karnataka and Rajasthan, reveal that these social pension schemes work reasonably well. Levels of leakage (corruption) are low, funds flow disprop...

    To analyse the effectiveness of a household conditional cash transfer programme (CCT) on antenatal care (ANC) coverage reported by women and ANC quality reported by midwives. The CCT was piloted as a cluster randomised control trial in 2007. Intent-to-treat parameters were estimated using linear regression and logistic regression. Secondary analysis of the longitudinal CCT impact evaluation survey, conducted in 2007 and 2009. This included 6869 pregnancies and 1407 midwives in 180 control subdistricts and 180 treated subdistricts in Indonesia. ANC component coverage index, a composite measure of each ANC service component as self-reported by women, and ANC provider quality index, a composite measure of ANC service provided as self-reported by midwives. Each index was created by principal component analysis (PCA). Specific ANC component items were also assessed. The CCT was associated with improved ANC component coverage index by 0.07 SD (95% CI 0.002 to 0.141). Women were more likely to receive the following assessments: weight (OR 1.56 (95% CI 1.25 to 1.95)), height (OR 1.41 (95% CI 1.247 to 1.947)), blood pressure (OR 1.36 (95% CI 1.045 to 1.761)), fundal height measurements (OR 1.65 (95% CI 1.372 to 1.992)), fetal heart beat monitoring (OR 1.29 (95% CI 1.006 to 1.653)), external pelvic examination (OR 1.28 (95% CI 1.086 to 1.505)), iron-folic acid pills (OR 1.42 (95% CI 1.081 to 1.859)) and information on pregnancy complications (OR 2.09 (95% CI 1.724 to 2.551)). On the supply side, the CCT had no significant effect on the ANC provider quality index based on reports from midwives. The CCT programme improved ANC coverage for women, but midwives did not improve ANC quality. The results suggest that enhanced ANC utilisation may not be sufficient to improve health outcomes, and steps to improve ANC quality are essential for programme impact. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    2014-01-01

    As the search for more effective HIV prevention strategies continues, increased attention is being paid to the potential role of cash transfers in prevention programming in sub-Saharan Africa. To date, studies testing the impact of both conditional and unconditional cash transfers on HIV-related behaviours and outcomes in sub-Saharan Africa have been relatively small-scale and their potential feasibility, costs and benefits at scale, among other things, remain largely unexplored. This article examines elements of a successful cash transfer program from Latin America and discusses challenges inherent in scaling-up such programs. The authors attempt a cost simulation of a cash transfer program for HIV prevention in South Africa comparing its cost and relative effectiveness--in number of HIV infections averted--against other prevention interventions. If a cash transfer program were to be taken to scale, the intervention would not have a substantial effect on decreasing the force of the epidemic in middle- and low-income countries. The integration of cash transfer programs into other sectors and linking them to a broader objective such as girls' educational attainment may be one way of addressing doubts raised by the authors regarding their value for HIV prevention.

    Many patients in low-income countries express preferences for high-quality health care but often end up with low-quality providers. We conducted a randomized controlled trial with pregnant women in Nairobi, Kenya, to analyze whether cash transfers, enhanced with behavioral "nudges," can help women deliver in facilities that are consistent with their preferences and are of higher quality. We tested two interventions. The first was a labeled cash transfer (LCT), which explained that the cash was to help women deliver where they wanted. The second was a cash transfer that combined labeling and a commitment by the recipient to deliver in a prespecified desired facility as a condition of receiving the final payment (L-CCT). The L-CCT improved patient-perceived quality of interpersonal care but not perceived technical quality of care. It also increased women's likelihood of delivering in facilities that met standards for routine and emergency newborn care but not the likelihood of delivering in facilities that met standards for obstetric care. The LCT had fewer measured benefits. Women preferred facilities with high technical and interpersonal care quality, but these quality measures were often negatively correlated within facilities. Even with cash transfers, many women still used poor-quality facilities. A larger study is warranted to determine whether the L-CCT can improve maternal and newborn outcomes.

  4. “No one says ‘No’ to money” – a mixed methods approach for evaluating conditional cash transfer schemes to improve girl children’s status in Haryana, India

    Science.gov (United States)

    2014-01-01

    Introduction Haryana was the first state in India to launch a conditional cash transfer (CCT) scheme in 1994. Initially it targeted all disadvantaged girls but was revised in 2005 to restrict it to second girl children of all groups. The benefit which accrued at girl attaining 18 years and subject to conditionalities of being fully immunized, studying till class 10 and remaining unmarried, was increased from about US$ 500 to US$ 2000. Using a mixed methods approach, we evaluated the implementation and possible impact of these two schemes. Methods A survey was conducted among 200 randomly selected respondents of Ballabgarh Block in Haryana to assess their perceptions of girl children and related schemes. A cohort of births during this period was assembled from population database of 28 villages in this block and changes in sex ratio at birth and in immunization coverage at one year of age among boys and girls was measured. Education levels and mean age at marriage of daughters were compared with daughters-in-law from outside Haryana. In-depth interviews were conducted among district level implementers of these schemes to assess their perceptions of programs’ implementation and impact. These were analyzed using a thematic approach. Results The perceptions of girls as a liability and poor (9% to 15%) awareness of the schemes was noted. The cohort analysis showed that while there has been an improvement in the indicators studied, these were similar to those seen among the control groups. Qualitative analysis identified a “conspiracy of silence” - an underplaying of the pervasiveness of the problem coupled with a passive implementation of the program and a clash between political culture of giving subsidies and a bureaucratic approach that imposed many conditionalities and documentary needs for availing of benefits. Conclusion The apparent lack of impact on the societal mindset calls for a revision in the current approach of addressing a social issue by a purely

    2015-08-01

    Full Text Available Several recently published studies analyze the effects of national conditional cash transfer (CCT programs, such as the Brazilian Bolsa Família and the Mexican Oportunidades, on presidential elections. Most of them show that these programs boost incumbents' electoral support among the poor. This research note is the first scholarly attempt to investigate this phenomenon at a lower-level unit of a federal state, by assessing the impact of a municipal cash transfer program on a mayoral election. Specifically, it investigates whether Renda Mínima, the cash transfer program of the city of Sao Paulo, affected beneficiaries' electoral behavior in favor of the incumbent candidate in the 2004 mayoral election. This note analyzes survey data from CEBRAP/IBOPE and shows that cash transfers did, indeed, affect beneficiaries' behavior in the predicted direction, but only in cases where they did not benefit from any other CCT program, such as the federal Bolsa Família or the São Paulo state Renda Cidadã. These results suggest that the pro-incumbent effect of CCT programs may be diluted by similar programs launched by governments at other tiers of a federation, even if they are led by the same party.

    Full Text Available Cash transfer (CTs is an increasingly popular social protection mechanism used by many developing countries to improve the food security and nutritional status of lower socio-economic groups. This paper is a review of the literature regarding the impact of CT programs on the food security of recipient households in the developing countries, including Iran. We looked for all original studies, performed in the developing countries and published in any language, containing at least one outcome related to food and nutritional security of the beneficiary population using Pub Med, Iran Medex, SID (Scientific Information Database, ISI (Information Sciences Institute database, INP (Iran’s Nutrition Publication Abstracts, IRANDOC and Magiran. Searches used the following terms or keywords: “household food security”, “household food insecurity” and “cash transfer” on any publication published within 1990-2015. A total of 12 studies evaluating the influence of CT programs on the recipients’ food and nutrition security were identified. CT programs have the potential to deliver a range of benefits not only through reducing extreme poverty but also by providing effective support for broader human development objectives, including better nutrition, as well as health and education outputs and outcomes. The extent to which programs can have these different impacts will depend critically on the availability of complementary services, the local context, and the specifics of program design, including the transfer value. However, findings in Iran suggest that the replacement of staple food subsidies by CT has led to a significant increase in household food insecurity (especially marginal or mild food insecurity.

    Full Text Available Abstract Background Social grants have been found to have an impact on health and wellbeing in multiple settings. Who receives the grant, however, has been the subject of discussion with regards to how the money is spent and who benefits from the grant. Methods Using survey data from 1214 young women who were in the intervention arm and completed at least one annual visit in the HPTN 068 trial, and qualitative interview data from a subset of 38 participants, we examined spending of a cash transfer provided to young women conditioned on school attendance. Results We found that spending was largely determined and controlled by young women themselves and that the cash transfer was predominately spent on toiletries, clothing and school supplies. In interview data, young women discussed the significant role of cash transfers for adolescent identity, specifically with regard to independence from family and status within the peer network. There were almost no negative consequences from receiving the cash transfer. Conclusions We established that providing adolescents access to cash was not reported to be associated with social harms or negative consequences. Rather, spending of the cash facilitated appropriate adolescent developmental behaviours. The findings are encouraging at a time in which there is global interest in addressing the structural drivers of HIV risk, such as poverty, for young women.

    Full Text Available In 2005, India established a conditional cash transfer program called Janani Suraksha Yojana (JSY, to increase institutional delivery and encourage the use of reproductive and child health-related services.To assess the effect of maternal receipt of financial assistance from JSY on childhood immunizations, post-partum care, breastfeeding practices, and care-seeking behaviors.We use data from the latest district-level household survey (2007-2008 to conduct a propensity score matching analysis with logistic regression. We conduct the analyses at the national level as well as separately across groups of states classified as high-focus and non-high-focus. We carry out several sensitivity analyses including a subgroup analysis stratified by possession of an immunization card.Receipt of financial assistance from JSY led to an increase in immunization rates ranging from 3.1 (95%CI 2.2-4.0 percentage points for one dose of polio vaccine to 9.1 (95%CI 7.5-10.7 percentage points in the proportion of fully vaccinated children. Our findings also indicate JSY led to increased post-partum check-up rates and healthy early breastfeeding practices around the time of childbirth. No effect of JSY was found on exclusive breastfeeding practices and care-seeking behaviors. Effect sizes were consistently larger in states identified as being a key focus for the program. In an analysis stratified by possession of an immunization card, there was little to no effect of JSY among those with vaccination cards, while the effect size was much larger than the base case results for those missing vaccination cards, across nearly all immunization outcomes.Early results suggest the JSY program led to a significant increase in childhood immunization rates and some healthy reproductive health behaviors, but the structuring of financial incentives to pregnant women and health workers warrants further review. Causal interpretation of our results relies on the assumption that

    Cash transfer programmes are increasingly recognised as promising and scalable interventions that can promote the health and development of children. However, concerns have been raised about the potential for cash transfers to contribute to social division, jealousy and conflict at a community level. Against this background, and in our interest to promote community participation in cash transfer programmes, we examine local perceptions of a community-led cash transfer programme in Eastern Zimbabwe. We collected and analysed data from 35 individual interviews and three focus group discussions, involving 24 key informants (community committee members and programme implementers), 24 cash transfer beneficiaries, of which four were youth, and 14 non-beneficiaries. Transcripts were subjected to thematic analysis and coding to generate concepts. Study participants described the programme as participatory, fair and transparent - reducing the likelihood of jealousy. The programme was perceived to have had a substantial impact on children's health and education, primarily through aiding parents and guardians to better cater for their children's needs. Moreover, participants alluded to the potential of the programme to facilitate more transformational change, for example by enabling families to invest money in assets and income generating activities and by promoting a community-wide sense of responsibility for the support of orphaned and vulnerable children. Community participation, combined with the perceived impact of the cash transfer programme, led community members to speak enthusiastically about the programme. We conclude that community-led cash transfer programmes have the potential to open up for possibilities of participation and community agency that enable social acceptability and limit social divisiveness.

  15. The effects of cash transfers and vouchers on the use and quality of maternity care services: A systematic review.

    2017-01-01

    Cash transfers and vouchers are forms of 'demand-side financing' that have been widely used to promote maternal and newborn health in low- and middle-income countries during the last 15 years. This systematic review consolidates evidence from seven published systematic reviews on the effects of different types of cash transfers and vouchers on the use and quality of maternity care services, and updates the systematic searches to June 2015 using the Joanna Briggs Institute approach for systematic reviewing. The review protocol for this update was registered with PROSPERO (CRD42015020637). Data from 51 studies (15 more than previous reviews) and 22 cash transfer and voucher programmes suggest that approaches tied to service use (either via payment conditionalities or vouchers for selected services) can increase use of antenatal care, use of a skilled attendant at birth and in the case of vouchers, postnatal care too. The strongest evidence of positive effect was for conditional cash transfers and uptake of antenatal care, and for vouchers for maternity care services and birth with a skilled birth attendant. However, effects appear to be shaped by a complex set of social and healthcare system barriers and facilitators. Studies have typically focused on an initial programme period, usually two or three years after initiation, and many lack a counterfactual comparison with supply-side investment. There are few studies to indicate that programmes have led to improvements in quality of maternity care or maternal and newborn health outcomes. Future research should use multiple intervention arms to compare cost-effectiveness with similar investment in public services, and should look beyond short- to medium-term service utilisation by examining programme costs, longer-term effects on service utilisation and health outcomes, and the equity of those effects.

    Background Cash transfers and vouchers are forms of ‘demand-side financing’ that have been widely used to promote maternal and newborn health in low- and middle-income countries during the last 15 years. Methods This systematic review consolidates evidence from seven published systematic reviews on the effects of different types of cash transfers and vouchers on the use and quality of maternity care services, and updates the systematic searches to June 2015 using the Joanna Briggs Institute approach for systematic reviewing. The review protocol for this update was registered with PROSPERO (CRD42015020637). Results Data from 51 studies (15 more than previous reviews) and 22 cash transfer and voucher programmes suggest that approaches tied to service use (either via payment conditionalities or vouchers for selected services) can increase use of antenatal care, use of a skilled attendant at birth and in the case of vouchers, postnatal care too. The strongest evidence of positive effect was for conditional cash transfers and uptake of antenatal care, and for vouchers for maternity care services and birth with a skilled birth attendant. However, effects appear to be shaped by a complex set of social and healthcare system barriers and facilitators.

    This study aims to see the impact of direct cash transfer program for 2008/2009 on household consumption of food, nonfood, education, and health in Central Java Province. The study is expected to provide important findings for the improvement of a similar program in the future. This study findings that (1) the increasing in food and non-food consumption for direct cash transfer recipients than non direct cash transfer recipients; (2) the impact of households expenditure on education for direct cash transfer recipients is higher than non direct cash transfer recipients; (3) the impact of households expenditure on health for direct cash transfer recipients is lower than non direct cash transfer recipients. This study recommended that (1) implementation of direct cash transfer program 2008/2009 must be managed to be better because this program can defend household welfare. It shows from several indicators of well-being such as consumption spending, education, and health; (2) data targets for poor households (very poor, poor, nearly poor) must be updated.

    Full Text Available Abstract Background India launched a national conditional cash transfer program, Janani Suraksha Yojana (JSY, aimed at reducing maternal mortality by promoting institutional delivery in 2005. It provides a cash incentive to women who give birth in public health facilities. This paper studies the extent of program uptake, reasons for participation/non participation, factors associated with non uptake of the program, and the role played by a program volunteer, accredited social health activist (ASHA, among mothers in Ujjain district in Madhya Pradesh, India. Methods A cross-sectional study was conducted from January to May 2011 among women giving birth in 30 villages in Ujjain district. A semi-structured questionnaire was administered to 418 women who delivered in 2009. Socio-demographic and pregnancy related characteristics, role of the ASHA during delivery, receipt of the incentive, and reasons for place of delivery were collected. Multinomial regression analysis was used to identify predictors for the outcome variables; program delivery, private facility delivery, or a home delivery. Results The majority of deliveries (318/418; 76% took place within the JSY program; 81% of all mothers below poverty line delivered in the program. Ninety percent of the women had prior knowledge of the program. Most program mothers reported receiving the cash incentive within two weeks of delivery. The ASHA's influence on the mother's decision on where to deliver appeared limited. Women who were uneducated, multiparious or lacked prior knowledge of the JSY program were significantly more likely to deliver at home. Conclusion In this study, a large proportion of women delivered under the program. Most mothers reporting timely receipt of the cash transfer. Nevertheless, there is still a subset of mothers delivering at home, who do not or cannot access emergency obstetric care under the program and remain at risk of maternal death.

    Assume that the households of a country are socially classified according to the monthly total income, and that they can be part of a lower, a middle or an upper class. By using multi-agent systems, here we model and simulate the economic evolution of households which earn a wage, pay taxes and invest in education. The return of the education investment is monthly added to the salary of the family, and it is function of the corresponding grand total put in education along the time. When a family is unemployed, we consider that it receives cash due to a social program made by the government. The time evolution of the percentages of households belonging to each class is investigated by varying the government investment in such a program of cash transfer and the proportion of employed households in the population. We show that the government should invest in the unemployed lower class if it intends a growth of the middle class. We also propose and analyze a mean-field approximation written in terms of ordinary differential equations. In addition, we verify that our model fits real data from Brazil, in the period between 2003 (when the cash transfer program Bolsa Família was launched) and 2011.

    Summary Time discounting is thought to influence decision-making in almost every sphere of life, including personal finances, diet, exercise and sexual behavior. In this article we provide evidence on whether a national poverty alleviation program in Kenya can affect inter-temporal decisions. We administered a preferences module as part of a large-scale impact evaluation of the Kenyan Government’s Cash Transfer for Orphans and Vulnerable Children. Four years into the program we find that individuals in the treatment group are only marginally more likely to wait for future money, due in part to the erosion of the value of the transfer by inflation. However among the poorest households for whom the value of transfer is still relatively large we find significant program effects on the propensity to wait. We also find strong program effects among those who have access to credit markets though the program itself does not improve access to credit. PMID:28260842

  9. Cash transfers and early childhood care and education in Zimbabwe: A critical inquiry to discourse, theory and practice

    Full Text Available Cash transfer based social protection can potentially contribute positively upon targeted beneficiaries on a variety of developmental aspects. This study explored the pilot and scaled-up phases of the Harmonised Social Cash Transfer program to determine impacts towards improving under-eight children’s access to food, education, and health services. Stories of significant change were gathered in retrospect from purposively sampled caregivers and children beneficiaries. Based on thematic and guided analysis, it emerged that the programmes’ theoretical and practical approaches renders the interventions less effective as impact assessment is narrowed to the early childhood cohort. This is furthered by relatively insufficient size of grants disbursed per household and commodity supply-side challenges. Consequently, a review to theoretical and practical tenets of the cash transfer approach becomes imminent in the Zimbabwean context. Targeting criteria needs refinement and supplemented with policy and multi-faceted public investment to address underlying limitations to impact on young children.

    This paper reports analysis of the impact of Kenya’s Cash Transfer for Orphans and Vulnerable Children Programme on the household decisions on productive activities using data from a randomized experimental design. Results show that the programme had a positive and significant impact on food consumption coming from home production, accumulation of productive assets, especially on the ownership of small livestock and on formation of nonfarm enterprise, especially for females. The programme has provided more flexibility to families in terms of labour allocation decisions, particularly for those who are geographically isolated. The programme was also found to have reduced child labour, an important objective of the programme. However we find very little impact of the programme on direct indicators of crop production.

    Poverty is a chronic stressor that can lead to poor physical and mental health. This study examines whether two similar government poverty alleviation programs reduced the levels of perceived stress and poverty among poor households in Zambia. Secondary data from two cluster randomized controlled trials were used to evaluate the impacts of two unconditional cash transfer programs in Zambia. Participants were interviewed at baseline and followed over 36 months. Perceived stress among female caregivers was assessed using the Cohen Perceived Stress Scale (PSS). Poverty indicators assessed included per capita expenditure, household food security, and (nonproductive) asset ownership. Fixed effects and ordinary least squares regressions were run, controlling for age, education, marital status, household demographics, location, and poverty status at baseline. Cash transfers did not reduce perceived stress but improved economic security (per capita consumption expenditure, food insecurity, and asset ownership). Among these poverty indicators, only food insecurity was associated with perceived stress. Age and education showed no consistent association with stress, whereas death of a household member was associated with higher stress levels. In this setting, perceived stress was not reduced by a positive income shock but was correlated with food insecurity and household deaths, suggesting that food security is an important stressor in this context. Although the program did reduce food insecurity, the size of the reduction was not enough to generate a statistically significant change in stress levels. The measure used in this study appears not to be correlated with characteristics to which it has been linked in other settings, and thus, further research is needed to examine whether this widely used perceived stress measure appropriately captures the concept of perceived stress in this population.

    Prenatal care is recommended during pregnancy to improve neonatal and maternal outcomes. Women of lower socioeconomic status (SES) are less compliant to recommended prenatal care and suffer a higher risk of adverse perinatal outcomes. Several attempts to encourage optimal pregnancy follow-up have shown controversial results, particularly in high-income countries. Few studies have assessed financial incentives to encourage prenatal care, and none reported materno-fetal events as the primary outcome. Our study aims to determine whether financial incentives could improve pregnancy outcomes in women with low SES in a high-income country. This pragmatic cluster-randomised clinical trial includes pregnant women with the following criteria: (1) age above 18 years, (2) first pregnancy visit before 26 weeks of gestation and (3) belonging to a socioeconomically disadvantaged group. The intervention consists in offering financial incentives conditional on attending scheduled pregnancy follow-up consultations. Clusters are 2-month periods with random turnover across centres. A composite outcome of maternal and neonatal morbidity and mortality is the primary endpoint. Secondary endpoints include maternal or neonatal outcomes assessed separately, qualitative assessment of the perception of the intervention and cost-effectiveness analysis for which children will be followed to the end of their first year through the French health insurance database. The study started in June 2016, and based on an expected decrease in the primary endpoint from 18% to 14% in the intervention group, we plan to include 2000 women in each group. Ethics approval was first gained on 28 September 2014. An independent data security and monitoring committee has been established. Results of the main trial and each of the secondary analyses will be submitted for publication in a peer-reviewed journal.

    Conditional transfer programs are increasingly popular, but the impact on household nutrient consumption has not been studied. We evaluated the impact of the Programa de Apoyo Alimentario (PAL), a cash and in-kind transfer program, on the energy and nutrient consumption of poor rural households in Mexico. The program has been shown to reduce poverty. Beneficiary households received either a food basket (including micronutrient-fortified milk) or cash. A random sample of 206 rural communities in Southern Mexico was randomly assigned to 1 of 4 groups: a monthly food basket with or without health and nutrition education, a cash transfer with a cost to the government equivalent to the food basket (14 USD/mo) with education, or control. The impact after 14 mo of exposure was estimated in a panel of 5823 households using a double difference regression model with household fixed effects. PAL was associated with increases (P consumption of total energy (5-9%), energy from fruits and vegetables (24-28%), and energy from animal source foods (24-39%). It also affected iron, zinc, and vitamin A and C consumption (P consumption of energy and all nutrients was greater in the food basket group (P energy-deficient should be carefully redesigned to ensure that pulling poor families out of poverty leads to improved micronutrient intake but not to increased energy consumption.

    The Janani Suraksha Yojana, India's "safe motherhood program," is a conditional cash transfer to encourage women to give birth in health facilities. Despite the program's apparent success in increasing facility-based births, quantitative evaluations have not found corresponding improvements in health outcomes. This study analyses original qualitative data collected between January, 2012 and November, 2013 in a rural district in Uttar Pradesh to address the question of why the program has not improved health outcomes. It finds that health service providers are focused on capturing economic rents associated with the program, and provide an extremely poor quality care. Further, the program does not ultimately provide beneficiaries a large net monetary transfer at the time of birth. Based on a detailed accounting of the monetary costs of hospital and home deliveries, this study finds that the value of the transfer to beneficiaries is small due to costs associated with hospital births. Finally, this study also documents important emotional and psychological costs to women of delivering in the hospital. These findings suggest the need for a substantial rethinking of the program, paying careful attention to incentivizing health outcomes. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Illness-related costs for patients with tuberculosis (TB) ≥20% of pre-illness annual household income predict adverse treatment outcomes and have been termed "catastrophic." Social protection initiatives, including cash transfers, are endorsed to help prevent catastrophic costs. With this aim, cash transfers may either be provided to defray TB-related costs of households with a confirmed TB diagnosis (termed a "TB-specific" approach); or to increase income of households with high TB risk to strengthen their economic resilience (termed a "TB-sensitive" approach). The impact of cash transfers provided with each of these approaches might vary. We undertook an economic modelling study from the patient perspective to compare the potential of these 2 cash transfer approaches to prevent catastrophic costs. Model inputs for 7 low- and middle-income countries (Brazil, Colombia, Ecuador, Ghana, Mexico, Tanzania, and Yemen) were retrieved by literature review and included countries' mean patient TB-related costs, mean household income, mean cash transfers, and estimated TB-specific and TB-sensitive target populations. Analyses were completed for drug-susceptible (DS) TB-related costs in all 7 out of 7 countries, and additionally for drug-resistant (DR) TB-related costs in 1 of the 7 countries with available data. All cost data were reported in 2013 international dollars ($). The target population for TB-specific cash transfers was poor households with a confirmed TB diagnosis, and for TB-sensitive cash transfers was poor households already targeted by countries' established poverty-reduction cash transfer programme. Cash transfers offered in countries, unrelated to TB, ranged from $217 to $1,091/year/household. Before cash transfers, DS TB-related costs were catastrophic in 6 out of 7 countries. If cash transfers were provided with a TB-specific approach, alone they would be insufficient to prevent DS TB catastrophic costs in 4 out of 6 countries, and when increased enough

    Maternal depression is an important public health concern. We investigated whether a national-scale initiative that provides cash transfers to women giving birth in government health facilities, the Janani Suraksha Yojana (JSY), reduced maternal depression in India's largest state, Uttar Pradesh. Using primary data on 1695 women collected in early 2015, our quasi-experimental design exploited the fact that some women did not receive the JSY cash due to administrative problems in its disbursement - reasons that are unlikely to be correlated with determinants of maternal depression. We found that receipt of the cash was associated with an 8.5% reduction in the continuous measure of maternal depression and a 36% reduction in moderate depression. There was no evidence of an association with measures of emotional well-being, namely happiness and worry. The results suggest that the JSY had a clinically meaningful effect in reducing the burden of maternal depression, possibly by lessening the financial strain of delivery care. They contribute to the evidence that financial incentive schemes may have public health benefits beyond improving uptake of targeted health services. Copyright © 2016 The Authors.

    This study examined associations between sexual initiation, unprotected sex, and having multiple sex partners in the past year with participation in a three-year empowerment program targeting orphan and vulnerable children (OVC). The Kenya-based program combines community-conditioned cash transfer, psychosocial empowerment, health education, and microenterprise development. Program participants (n = 1,060) were interviewed in a cross-sectional design. Analyses used gender-stratified hierarchical logit models to assess program participation and other potential predictors. Significant predictors of increased female sexual activity included less program exposure, higher age, younger age at most recent parental death, fewer years of schooling, higher food consumption, higher psychological resilience, and lower general self-efficacy. Significant predictors of increased male sexual activity included more program exposure, higher age, better food consumption, not having a living father, and literacy. Findings support a nuanced view of current cash transfer programs, where female sexual activity may be reduced through improved financial status but male sexual activity may increase. Targeting of OVC sexual risk behaviors would likely benefit from being tailored according to associations found in this study. Data suggest involving fathers in sexual education, targeting women who lost a parent at a younger age, and providing social support for female OVC may decrease risk of human immunodeficiency virus (HIV) transmission.

    HIV infection has profound clinical and economic costs at the household level. This is particularly important in low-income settings, where access to additional sources of income or loans may be limited. While several microfinance interventions have been proposed, unconditional cash grants, a strategy to allow participants to choose how to use finances that may improve household security and health, has not previously been evaluated. We examined the effect of an unconditional cash transfer to HIV-infected individuals using a 2 x 2 factorial randomised trial in two rural districts in Uganda. Our primary outcomes were changes in CD4 cell count, sexual behaviors, and adherence to ART. Secondary outcomes were changes in household food security and adult mental health. We applied a Bayesian approach for our primary analysis. We randomized 2170 patients as participatants, with 1081 receiving a cash grant. We found no important intervention effects on CD4 t-cell counts between groups (mean difference [MD] 35.48, 95% Credible Interval [CrI] -59.9-1131.6), food security (odds ratio [OR] 1.22, 95% CrI: 0.47, 3.02), medication adherence (OR 3.15, 95% CrI: 0.58, 18.15), or sexual behavior (OR 0.45 95% CrI: 0.12, 1.55), or health expenditure in the previous 3 weeks (Mean Difference $2.65, 95% CrI: -9.30, 15.69). In secondary analysis, we detected an effect of mental planning on CD4 change between groups (104.2 cells, 9% CrI: 5.99, 202.16). We did not have data on viral load outcomes. Although all outcomes were associated with favorable point estimates, our trial did not demonstrate important effects of unconditional cash grants on health outcomes.

    Unconditional and conditional cash transfer programmes (UCT and CCT) show potential to improve the well-being of orphans and other children made vulnerable by HIV/AIDS (OVC). We address the gap in current understanding about the extent to which household-based cash transfers differentially impact individual children's outcomes, according to risk or protective factors such as orphan status and household assets. Data were obtained from a cluster-randomised controlled trial in eastern Zimbabwe, with random assignment to three study arms - UCT, CCT or control. The sample included 5,331 children ages 6-17 from 1,697 households. Generalized linear mixed models were specified to predict OVC health vulnerability (child chronic illness and disability) and social protection (birth registration and 90% school attendance). Models included child-level risk factors (age, orphan status); household risk factors (adults with chronic illnesses and disabilities, greater household size); and household protective factors (including asset-holding). Interactions were systematically tested. Orphan status was associated with decreased likelihood for birth registration, and paternal orphans and children for whom both parents' survival status was unknown were less likely to attend school. In the UCT arm, paternal orphans fared better in likelihood of birth registration compared with non-paternal orphans. Effects of study arms on outcomes were not moderated by any other risk or protective factors. High household asset-holding was associated with decreased likelihood of child's chronic illness and increased birth registration and school attendance, but household assets did not moderate the effects of cash transfers on risk or protective factors. Orphaned children are at higher risk for poor social protection outcomes even when cared for in family-based settings. UCT and CCT each produced direct effects on children's social protection which are not moderated by other child- and household

    Full text: Cash transfers (CTs) are becoming a popular intervention of choice by agencies and NGOs as a complementary or alternative approach to food-based assistance, as part of an emergency response. There is strong evidence that CT programmes lead to an increase in household income and protect household assets from being sold, resulting in an increase in food quantity and improved dietary diversity which in turn are thought to protect children from malnutrition. However, the evidence for an impact of CTs on undernutrition is mixed and inconclusive. Despite this, CTs are increasingly being used in emergency responses with an objective of preventing acute malnutrition. The main objective was to assess the effect of an unconditional CT implemented as part of an emergency response to food insecurity during a declared state of emergency in Aguie district, Maradi, Niger. This was a prospective observational study involving 6 consecutive months of data collection starting pre-intervention in April 2012 (baseline), on the same cohort of ‘poor’ and ‘very poor’ households, with a non-acutely malnourished child 6-36 months, enrolled by Save the Children in an unconditional CT programme (n = 412). Analyses using pre-post intervention data were carried out to assess changes in the potential mediating factors within the causal pathway between CT and acute malnutrition over time and to estimate risk factors associated with acute malnutrition. The study showed that the living standards of ‘poor’ and ‘very poor’ households improved; indicated by reduction in poverty (improvement in household expenditures, incomes, employment, asset protection, wealth rank and access to social networks) and improvement in household food security (reduced household hunger and greater household and child dietary diversity). Child anthropometric outcomes (weight-for-height and MUAC) significantly improved (p 0•05). The results from this study are consistent with the available

    Cash transfers (CTs) are now high on the agenda of most governments in low- and middle-income countries. Within the field of health promotion, CTs constitute a healthy public policy initiative as they have the potential to address the social determinants of health (SDoH) and health inequalities. A systematic review was conducted to synthesise the evidence on CTs' impacts on SDoH and health inequalities in sub-Saharan Africa, and to identify the barriers and facilitators of effective CTs. Twenty-one electronic databases and the websites of 14 key organizations were searched in addition to grey literature and hand searching of selected journals for quantitative and qualitative studies on CTs' impacts on SDoH and health outcomes. Out of 182 full texts screened for eligibility, 79 reports that reported findings from 53 studies were included in the final review. The studies were undertaken within 24 CTs comprising 11 unconditional CTs (UCTs), 8 conditional CTs (CCTs) and 5 combined UCTs and CCTs. The review found that CTs can be effective in tackling structural determinants of health such as financial poverty, education, household resilience, child labour, social capital and social cohesion, civic participation, and birth registration. The review further found that CTs modify intermediate determinants such as nutrition, dietary diversity, child deprivation, sexual risk behaviours, teen pregnancy and early marriage. In conjunction with their influence on SDoH, there is moderate evidence from the review that CTs impact on health and quality of life outcomes. The review also found many factors relating to intervention design features, macro-economic stability, household dynamics and community acceptance of programs that could influence the effectiveness of CTs. The external validity of the review findings is strong as the findings are largely consistent with those from Latin America. The findings thus provide useful insights to policy makers and managers and can be used to

    We examined the effects of Ecuador's Bono de Desarrollo Humano (BDH)--an unconditional cash transfer program that was rolled-out using a randomized design--on health and development outcomes in very young children. Communities that were randomly assigned to the treatment group began receiving the BDH in 2004 and those randomly assigned to the comparison group began receiving benefits two years later. Families enrolled in the BDH received a monthly cash stipend ($15USD) representing an approximate 6-10% increase in household income. Participants analyzed in this study are children aged 12-35 months from treatment (n = 797) and comparison (n = 399) communities in rural and urban Ecuador. Main outcomes measured were language skills (the Fundación MacArthur Inventorio del Desarollo de Habilidades Comunicativas-Breve), height-for-age z-score, and hemoglobin concentration. Results indicate that in rural areas, being randomized to receive the BDH in very early childhood led to significantly better performance on the number of words a child was saying, and on the probability that the child was combining two or more words. There were no significant effects on language development for children in urban areas and there were no effects on height-for-age z-score or hemoglobin concentration in rural or urban areas. A limited number of potential pathways with respect to cognitive/language stimulation, health behaviors, and parenting quality were also explored. Findings indicate that compared to children in comparison areas, rural children in treatment areas were more likely to have received vitamin A or iron supplementation and have been bought a toy in the past six months. This study provides evidence for significant benefits of an unconditional cash transfer program for language development in very young children in rural areas. Copyright © 2011 Elsevier Ltd.

    Cash transfer programmes targeting children are considered an effective strategy for addressing child poverty and for improving child health outcomes in developing countries. In South Africa, the Child Support Grant (CSG) is the largest cash transfer programme targeting children from poor households. The present paper investigates the association of the duration of CSG receipt with child growth at 2 years in three diverse areas of South Africa. The study analysed data on CSG receipt and anthropometric measurements from children. Predictors of stunting were assessed using a backward regression model. Paarl (peri-urban), Rietvlei (rural) and Umlazi (urban township), South Africa, 2008. Children (n 746), median age 22 months. High rates of stunting were observed in Umlazi (28 %), Rietvlei (20 %) and Paarl (17 %). Duration of CSG receipt had no effect on stunting. HIV exposure (adjusted OR=2·30; 95 % CI 1·31, 4·03) and low birth weight (adjusted=OR 2·01, 95 % CI 1·02, 3·96) were associated with stunting, and maternal education had a protective effect on stunting. Our findings suggest that, despite the presence of the CSG, high rates of stunting among poor children continue unabated in South Africa. We argue that the effect of the CSG on nutritional status may have been eroded by food price inflation and limited progress in the provision of other important interventions and social services.

    Unconditional cash transfers (UCTs; provided without obligation) for reducing poverty and vulnerabilities (e.g. orphanhood, old age or HIV infection) are a type of social protection intervention that addresses a key social determinant of health (income) in low- and middle-income countries (LMICs). The relative effectiveness of UCTs compared with conditional cash transfers (CCTs; provided so long as the recipient engages in prescribed behaviours such as using a health service or attending school) is unknown. To assess the effects of UCTs for improving health services use and health outcomes in vulnerable children and adults in LMICs. Secondary objectives are to assess the effects of UCTs on social determinants of health and healthcare expenditure and to compare to effects of UCTs versus CCTs. We searched 17 electronic academic databases, including the Cochrane Public Health Group Specialised Register, the Cochrane Database of Systematic Reviews (the Cochrane Library 2017, Issue 5), MEDLINE and Embase, in May 2017. We also searched six electronic grey literature databases and websites of key organisations, handsearched key journals and included records, and sought expert advice. We included both parallel group and cluster-randomised controlled trials (RCTs), quasi-RCTs, cohort and controlled before-and-after (CBAs) studies, and interrupted time series studies of UCT interventions in children (0 to 17 years) and adults (18 years or older) in LMICs. Comparison groups received either no UCT or a smaller UCT. Our primary outcomes were any health services use or health outcome. Two reviewers independently screened potentially relevant records for inclusion criteria, extracted data and assessed the risk of bias. We tried to obtain missing data from study authors if feasible. For cluster-RCTs, we generally calculated risk ratios for dichotomous outcomes from crude frequency measures in approximately correct analyses. Meta-analyses applied the inverse variance or Mantel

    Full Text Available Abstract Background Acute malnutrition is a public health issue worldwide, and particularly in the Eastern region of Burkina Faso. Following a needs assessment, unconditional seasonal, multiannual cash transfers were implemented as a safety net to prevent childhood undernutrition. The objectives of this study were to explore the types of purchases made by beneficiaries of this cash transfer program and to understand the perceived effects of and changes induced by regular cash transfers in the daily lives of women, and at the household and community level. Methods The design of this study was a two-arm cluster randomized controlled trial. Qualitative data were collected each month during the cash transfer period for two years, leading to a total of more than 300 interviews and focus group discussions with various participants: beneficiary mothers, heads of households, mothers-in-law, co-wives, key members of the community, and participants of the control group. Results The two main types of expenses reported were food and health care for the child and the whole family. The program was also associated with positive perceived changes at the household level, mainly related to gender equality and improvement of women’s status, and has promoted an increase in dignity and social integration of the poorest at the community level through cash sharing. Unexpected effects of this program included some women planning new pregnancies and some individuals not expecting the transfers to end. Conclusion Although the transfers were unconditional, the cash was mainly used to improve the children’s and households’ food security and health, which correspond to two main underlying causes of undernutrition. Therefore, spending mainly in these areas can help to prevent undernutrition in children. Trial registration ClinicalTrials.gov , identifier: NCT01866124 , registered May 7, 2013.

    Unconditional cash transfers (UCTs) are a common social protection intervention that increases income, a key social determinant of health, in disaster contexts in low- and middle-income countries (LMICs). To assess the effects of UCTs in improving health services use, health outcomes, social determinants of health, health care expenditure, and local markets and infrastructure in LMICs. We also compared the relative effectiveness of UCTs delivered in-hand with in-kind transfers, conditional cash transfers, and UCTs paid through other mechanisms. We searched 17 academic databases, including the Cochrane Public Health Group Specialised Register, the Cochrane Database of Systematic Reviews (The Cochrane Library 2014, Issue 7), MEDLINE, and EMBASE between May and July 2014 for any records published up until 4 May 2014. We also searched grey literature databases, organisational websites, reference lists of included records, and academic journals, as well as seeking expert advice. We included randomised and quasi-randomised controlled trials (RCTs), as well as cohort, interrupted time series, and controlled before-and-after studies (CBAs) on UCTs in LMICs. Primary outcomes were the use of health services and health outcomes. Two authors independently screened all potentially relevant records for inclusion criteria, extracted the data, and assessed the included studies' risk of bias. We requested missing information from the study authors. Three studies (one cluster-RCT and two CBAs) comprising a total of 13,885 participants (9640 children and 4245 adults) as well as 1200 households in two LMICs (Nicaragua and Niger) met the inclusion criteria. They examined five UCTs between USD 145 and USD 250 (or more, depending on household characteristics) that were provided by governmental, non-governmental or research organisations during experiments or pilot programmes in response to droughts. Two studies examined the effectiveness of UCTs, and one study examined the relative

    Bypassing health facilities for childbirth can be costly both for women and health systems. There have been some reports on this from Sub-Saharan African and from Nepal but none from India. India has implemented the Janani Suraksha Yojana (JSY), a large national conditional cash transfer program which has successfully increased the number of institutional births in India. This paper aims to study the extent of bypassing the nearest health facility offering intrapartum care in three districts of Madhya Pradesh, India, and to identify individual and facility determinants of bypassing in the context of the JSY program. Our results provide information to support the optimal utilization of facilities at different levels of the healthcare system for childbirth. Data was collected from 96 facilities (74 public) and 720 rural mothers who delivered at these facilities were interviewed. Multilevel logistic regression was used to analyze the data. Facility obstetric care functionality was assessed by the number of emergency obstetric care (EmOC) signal functions performed in the last three months. Thirty eighth percent of the mothers bypassed the nearest public facility for their current delivery. Primiparity, higher education, arriving by hired transport and a longer distance from home to the nearest facility increased the odds of bypassing a public facility for childbirth. The variance partition coefficient showed that 37% of the variation in bypassing the nearest public facility can be attributed to difference between facilities. The number of basic emergency obstetric care signal functions (AOR = 0.59, 95% CI 0.37-0.93), and the availability of free transportation at the nearest facility (AOR = 0.11, 95% CI 0.03-0.31) were protective factors against bypassing. The variation between facilities (MOR = 3.85) was more important than an individual's characteristics to explain bypassing in MP.

However, a decline in maternal mortality has only followed secular trends as seen from the beginning of the decade well before the programme began. We, therefore, examined the quality of intrapartum care provided in facilities under the JSY programme to study whether it ensures skilled attendance at birth. Design: 1 Non-participant observations (n=18 of intrapartum care during vaginal deliveries at a representative sample of 11 facilities in Madhya Pradesh to document what happens during intrapartum care. 2 Interviews (n=10 with providers to explore reasons for this care. Thematic framework analysis was used. Results: Three themes emerged from the data: 1 delivery environment is chaotic: delivery rooms were not conducive to safe, women-friendly care provision, and coordination between providers was poor. 2 Staff do not provide skilled care routinely: this emerged from observations that monitoring was limited to assessment of cervical dilatation, lack of readiness to provide key elements of care, and the execution of harmful/unnecessary practices coupled with poor techniques. 3 Dominant staff, passive recipients: staff sometimes threatened, abused, or ignored women during delivery; women were passive and accepted dominance and disrespect. Attendants served as ‘go-betweens’ patients and providers. The interviews with providers revealed their awareness of the compromised quality of care, but they were constrained by structural problems.

    This study assessed the costs and cost-efficiency of a mobile cash transfer implemented in Tapoa Province, Burkina Faso in the MAM'Out randomized controlled trial from June 2013 to December 2014, using mixed methods and taking a societal perspective by including costs to implementing partners and beneficiary households. Data were collected via interviews with implementing staff from the humanitarian agency and the private partner delivering the mobile money, focus group discussions with beneficiaries, and review of accounting databases. Costs were analyzed by input category and activity-based cost centers. cost-efficiency was analyzed by cost-transfer ratios (CTR) and cost per beneficiary. Qualitative analysis was conducted to identify themes related to implementing electronic cash transfers, and barriers to efficient implementation. The CTR was 0.82 from a societal perspective, within the same range as other humanitarian transfer programs; however the intervention did not achieve the same degree of cost-efficiency as other mobile transfer programs specifically. Challenges in coordination between humanitarian and private partners resulted in long wait times for beneficiaries, particularly in the first year of implementation. Sensitivity analyses indicated a potential 6% reduction in CTR through reducing beneficiary wait time by one-half. Actors reported that coordination challenges improved during the project, therefore inefficiencies likely would be resolved, and cost-efficiency improved, as the program passed the pilot phase. Despite the time required to establish trusting relationships among actors, and to set up a network of cash points in remote areas, this analysis showed that mobile transfers hold promise as a cost-efficient method of delivering cash in this setting. Implementation by local government would likely reduce costs greatly compared to those found in this study context, and improve cost-efficiency especially by subsidizing expansion of mobile

    transferência de renda sobre a segurança alimentar, independentemente do efeito de outras condições explicativas.OBJECTIVE: The 2004 National Household Survey Data was analyzed to test the hypothesis that cash transference from government social programs is associated with household food security. METHODS: Secondary data were used from the National Household Sample Survey which interviewed residents of 112,716 households. The present analysis included permanent and temporary private households, where food security items were informed by a resident of the household, restricting the collection of data to households with per capita monthly income of up to 1 minimum wage, representing 51.2% of the sample. Three models for estimating the amount of cash transference were developed; model 3 was chosen because it was less likely to overestimate effects. To analyze how cash transference affected the prevalence of food security, only households that received cash transference were included in the analysis, representing 14.2% of the interviewed households. The association between food security and cash transference, controlled for other independent variables, was estimated using a logistic regression model with stepwise method for each of the three income strata. RESULTS: The mean per capita cash transference was of R$81.68 per family. Multiple logistic regression showed an increased chance of food security of 8% per each R$10.00 contributed by social programs. Rural residence, male head of household, and Caucasian head of household were factors that also presented a higher chance of food security. CONCLUSION: The hypothesis was confirmed, showing a positive association between cash transfer and household food security, regardless of the effects of other explanatory factors.

    Full Text Available Objective: The aim of this study was to evaluate the effectiveness of the synergetic effect of child sensitive social protection programs, augmented by a capacity building for social protection and embedded within existing government’s targeted resource transfers for families on child nutritional status. Design: A repeat cross-sectional quasi-experimental design with measures taken pre- (October–December 2009 and post- (December 2014–February 2015 intervention in the intervention and comparison district. The comparison district received standard social welfare services in the form of targeted resource transfers (TRTs for eligible families. The intervention district received the TRTs plus a child cash payment, augmented by a capacity building for effective social protection outcomes. Propensity scores were used in difference-in-differences models to compare the changes over time between the intervention and control groups. Results: Propensity score matched/weighted models produced better results than the unmatched analyses, and hence we report findings from the radius matching.

    Experiments were performed on heat transfer and pressure drop of a supercritical pressure fluid flowing upward in a uniformly heated vertical tube of a small diameter, using HCFC22 as a test fluid. Following results were obtained. (1) Characteristics of the heat transfer are similar to those for the tubes of large diameter. (2) The effect of tube diameter on the heat transfer was seen for a 'normal heat transfer, but not for a 'deteriorated' heat transfer. (3) The limit heat flux for the occurrence of deterioration in heat transfer becomes larger with smaller diameter tube. (4) The Watts and Chou correlation has the best prediction performance for the present data in the 'normal' heat transfer region. (5) Frictional pressure drop becomes smaller than that for an isothermal flow in the region near the pseudocritical point, and this reduction was more remarkable for the deteriorated' heat transfer.

    2016-07-13

    There is increasing pressure to address the social determinants of health (SDoH) and health inequities through the implementation of culturally acceptable interventions particularly in Sub-Saharan Africa (SSA) where health outcomes are generally poor. Available evaluation research on cash transfers (CTs) suggests that the programs may influence the wider determinants of health in SSA; yet, there has been no attempt to synthesize the evidence regarding their contribution to tackling the SDoH and health inequalities. To date, nearly all the reviews on CTs' impact on health have predominantly featured evidence from Latin America with limited transferability to the social, cultural, and political environments in SSA. Therefore, the aim of this study is to undertake a systematic review to assess the role of CTs in tackling the wider determinants of health and health inequalities in SSA. A systematic review of published and unpublished literature on CTs' impact on health and health determinants covering the period 2000-2016 will be undertaken. Studies will be considered for inclusion if they present quantitative or qualitative data, including all relevant study designs. The SDoH conceptual framework will be used to guide the data extraction process. EPPI Reviewer software will be used for data management and analysis. Studies included in the review will be analyzed by narrative synthesis and/or meta-analysis as appropriate for the nature of the data retrieved. This review will provide empirical evidence on the impact of CTs on SDoH to inform CT policy, implementation, and research in SSA. The protocol follows the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). This protocol has been registered with the PROSPERO international prospective register of systematic reviews, reference CRD42015025015 .

    Full Text Available Orphaned and vulnerable adolescents (OVA in sub-Saharan Africa are at greater risk for adverse psychological outcomes compared with their non-OVA counterparts. Social interventions that provide cash transfers (CTs have been shown to improve health outcomes among young people, but little is known about their impact on the psychological wellbeing of OVA.Among OVA in western Kenya, we assessed the association between living in a household that received monthly unconditional government CTs and psychological wellbeing.We examined the likelihood of depression, anxiety, post-traumatic stress symptoms (PTSS and positive future outlook among 655 OVA aged between 10 and 18 years who lived in 300 randomly selected households in western Kenya that either received or did not receive unconditional monthly CTs.The mean age was 14.0 (SD 2.4 years and 329 (50.2% of the participants were female while 190 (29.0% were double orphans whose biological parents were both deceased.

    Cash-based transfer programmes are an emerging strategy in the prevention of wasting in children, especially targeted at vulnerable households during periods of food insecurity or during emergencies. However, the evidence surrounding the use of either cash or voucher transfer programmes in the humanitarian context and on nutritional outcomes is elusive. More evidence is needed not only to inform the global community of practice on best practices in humanitarian settings, but also to help strengthen national mitigation responses. The Research for Food Assistance on Nutrition Impact Pakistan study (REFANI-P) sets out to evaluate the impact of three cash-based interventions on nutritional outcomes in children aged less than five years from poor and very poor households in Dadu District. This four-arm parallel cluster randomised controlled trial is set among Action Against Hunger (ACF) programme villages in Dadu District, Sindh Province. Mothers are the target recipients of either seasonal unconditional cash transfers or fresh food vouchers. A comparison group receives 'standard care' provided by the ACF programme to which all groups have the same access. The primary outcomes are prevalence of wasting and mean weight-for-height Z-score (WHZ) in children. Impact will be assessed at 6 months and at 1 year from baseline. Using a theory-based approach we will determine 'how' the different interventions work by looking at the processes involved and the impact pathways following the theory of change developed for this context. Quantitative and qualitative data are collected on morbidity, health seeking, hygiene and nutrition behaviours, dietary diversity, haemoglobin concentration, women's empowerment, household food security and expenditures and social capital. The direct and indirect costs of each intervention borne by the implementing organisation and their partners as well as by beneficiaries and their communities are also assessed. The results of this trial will provide

    Full Text Available Cash management can be defined as the optimization of cash flows and investment of excess cash in a corporation. But from an international perspective, cash management becomes very complex because of different laws among countries that pertain to cross-border cash transfers. Besides, the value of cross-border cash transfers is affected by the exchange rate fluctuations. This article is concerned with the optimization of cash flows in a multinational corporation and examines centralized cash management approach and pooling technique in order to optimize the parent-subsidiary and inter-subsidiary cash flows.

  14. Demand-side financing for maternal and newborn health: what do we know about factors that affect implementation of cash transfers and voucher programmes?

    2017-08-31

    Demand-side financing (DSF) interventions, including cash transfers and vouchers, have been introduced to promote maternal and newborn health in a range of low- and middle-income countries. These interventions vary in design but have typically been used to increase health service utilisation by offsetting some financial costs for users, or increasing household income and incentivising 'healthy behaviours'. This article documents experiences and implementation factors associated with use of DSF in maternal and newborn health. A secondary analysis (using an adapted Supporting the Use of Research Evidence framework - SURE) was performed on studies that had previously been identified in a systematic review of evidence on DSF interventions in maternal and newborn health. The article draws on findings from 49 quantitative and 49 qualitative studies. The studies give insights on difficulties with exclusion of migrants, young and multiparous women, with demands for informal fees at facilities, and with challenges maintaining quality of care under increasing demand. Schemes experienced difficulties if communities faced long distances to reach participating facilities and poor access to transport, and where there was inadequate health infrastructure and human resources, shortages of medicines and problems with corruption. Studies that documented improved care-seeking indicated the importance of adequate programme scope (in terms of programme eligibility, size and timing of payments and voucher entitlements) to address the issue of concern, concurrent investments in supply-side capacity to sustain and/or improve quality of care, and awareness generation using community-based workers, leaders and women's groups. Evaluations spanning more than 15 years of implementation of DSF programmes reveal a complex picture of experiences that reflect the importance of financial and other social, geographical and health systems factors as barriers to accessing care. Careful design of DSF

    Full Text Available Abstract Background Intimate partner violence (IPV is highly prevalent and has detrimental effects on the physical and mental health of women across the world. Despite emerging evidence on the impacts of cash transfers on intimate partner violence, the pathways through which reductions in violence occur remain under-explored. A randomised controlled trial of a cash and in-kind food transfer programme on the northern border of Ecuador showed that transfers reduced physical or sexual violence by 30 %. This mixed methods study aimed to understand the pathways that led to this reduction. Methods We conducted a mixed methods study that combined secondary analysis from a randomised controlled trial relating to the impact of a transfer programme on IPV with in-depth interviews and focus group discussions with male and female beneficiaries. A sequential analysis strategy was followed, whereby qualitative results guided the choice of variables for the quantitative analysis and qualitative insights were used to help interpret the quantitative findings. Results We found qualitative and quantitative evidence that the intervention led to reductions in IPV through three pathways operating at the couple, household and individual level: i reduced day-to-day conflict and stress in the couple; ii improved household well-being and happiness; and iii increased women’s decision making, self-confidence and freedom of movement. We found little evidence that any type of IPV increased as a result of the transfers. Discussion While cash and in-kind transfers can be important programmatic tools for decreasing IPV, the positive effects observed in this study seem to depend on circumstances that may not exist in all settings or programmes, such as the inclusion of a training component. Moreover, the programme built upon rather than challenged traditional gender roles by targeting women as transfer beneficiaries and framing the intervention under the umbrella of food

All consenting married women aged 10-49 years, who had not had tubal ligation and whose husbands had not had vasectomy, were monitored for missed menses. Between 29 Dec 2013 and 28 Feb 2015 we recruited 25,092 pregnant women to surveillance and interventions: PLA alone (n = 5626; PLA plus food (10 kg/month of fortified wheat-soya 'Super Cereal', n = 6884; PLA plus cash (NPR750≈US$7.5/month, n = 7272; control (existing government programmes, n = 5310. 539 PLA groups discussed and implemented strategies to improve low birthweight, nutrition in pregnancy and hand washing.

    High out-of-pocket expenditures (OOPE) make delivery care difficult to access for a large proportion of India's population. Given that home deliveries increase the risk of maternal mortality, in 2005 the Indian Government implemented the Janani Suraksha Yojana (JSY) program to incentivize poor women to deliver in public health facilities by providing a cash transfer upon discharge. We study the OOPE among JSY beneficiaries and women who deliver at home, and predictors of OOPE in two districts of Madhya Pradesh. September 2013 to April 2015 a cross-sectional community-based survey was performed. All recently delivered women were interviewed to elicit delivery costs, socio-demographic characteristics and delivery related information. Most women (n = 1995, 84 %) delivered in JSY public health facility, the remaining 16 % (n = 386) delivered at home. Women who delivered under JSY program had a higher median, IQR OOPE ($8, 3-18) compared to home ($6, 2-13). Among JSY beneficiaries, poorest women had twice net gain ($20) versus wealthiest ($10) post cash transfer. Informal payments (64 %) and food/baby items (77 %) were the two most common sources of OOPE. OOPE made among JSY beneficiaries was pro-poor: poorer women made proportionally less expenditures compared to wealthier women. In an adjusted model, delivering in a JSY public facility increased odds of incurring expenditures (OR: 1.58, 95 % CI: 1.11-2.25) but at the same time to a 16 % (95 % CI: 0.73-0.96) decrease in the amount paid compared to home deliveries. OOPE is prevalent among JSY beneficiaries as well in home deliveries. In JSY, OOPE varies by income quintile: wealthier quintiles pay more OOPE. However the cash incentive is adequate enough to provide a net gain for all quintiles. OOPE was largely due to indirect costs and not direct medical payments. The program seems to be effective in providing financial protection for the most vulnerable groups.

  1. Conditional transfer of emission rights. Not a good idea

    International Nuclear Information System (INIS)

    Van Engelen, Th.C.J.A.

    2004-01-01

    The Dutch government embraces the idea that trading of emission allowances is a useful way of reducing the emission of harmful gasses. In the current plans to amend the Environmental Management Act, however, the legislator has chosen for a system where allowances may only be transferred in accordance with strict conditions. These conditions do not provide a legal framework for an efficient emission allowances trading market. As a result, Dutch industry will potentially be placed in an unfavourable position. The legislator, it is suggested, should opt for fully transferable allowances. It is crucial that an efficient international market for trading in allowances is established. This means that it should be possible to trade these allowances easily, without excessive legal restrictions. The aim of the legislator is to prevent extreme situations in this market. While its concerns are valid, however, the legislator has missed the mark by choosing a system whereby transfer of allowances is subject to excessive conditions. The legal consequence of not fulfilling one or more of the conditions during the sale is that the allowance will not be legally transferred, and the seller will remain the proprietor of the allowance, without either the seller or the buyer being aware of the situation. It is clear that this would be an unworkable situation as it would not be possible from a practical angle to simply and quickly check previous transactions. Overall, this would result in high transactions costs, which in turn would be a barrier to an efficient market. In summary, an efficient market in emission allowances seems to be an illusion if the transfer of allowances are subject to such conditions as are presently envisaged by the law. It is suggested that the legislator can reach its goals by dropping the conditions for transfers and by supervising the transactions through administrative and criminal procedures instead. This will not affect the owners-hip of emission allowances

  2. Managing the Cash and Liquidity of the Croatian Budget

    Directory of Open Access Journals (Sweden)

    Anto Bajo

    2005-06-01

    Full Text Available The principal proposition this paper will endeavour to maintain is that the liquidity of the budget is not fully managed by the Ministry of Finance, which is why it is unable, in collaboration with the Croatian National Bank, to rein in and slow down the growth in short-term public debt. Only since 2001, thanks to institutional improvements, have the conditions been created in the Ministry of Finance for cash and liquidity management. Thus payments operations, previously in the hands of a government institution, were taken over by the banks; the financial operations of budgetary spending agencies were channelled via the Single Account of the Treasury; and government deposits were gradually transferred from numerous commercial banks to the Single Account of the Treasury in the Croatian National Bank and the state-owned Croatian Postal Bank. Unfortunately, however, the Ministry of Finance, in collaboration with the Croatian National Bank, still carries out no operation of cash and liquidity management within the government Treasury system, nor does it operate on the money market with its surplus budgetary resources. Because of this state of affairs, management of the cash and liquidity of the central government budget is within the purview of the commercial banks.

    2018-02-01

    Full Text Available This text discusses the implementation of conditional income transfer programs in Latin America as a strategy to confront poverty in the region. It synthetically contextualizes Latin American development over time, using statistical data to reveal not only the high levels of poverty, but also educational and health conditions. These programs, as a rule, seek to alleviate and overcome poverty through monetary disbursements and fulfillment of health and educational agendas that, in thesis, increase the human capital of the poor and allow overcoming poverty in the long term. It concludes that despite the benefits for the families, the conditional income transfer programs of Latin America, on their own, are still not capable of confronting the structural poverty that marks the region, and are promoting palliatives for the poor living conditions, without overcoming them.

    The administrative controls associated with transferring containers from one criticality hazard control zone to another in the Argonne National Laboratory (ANL) Fuel Conditioning Facility (FCF) are described. FCF, located at the ANL-West site near Idaho Falls, Idaho, is used to remotely process spent sodium bonded metallic fuel for disposition. The process involves nearly forty widely varying material forms and types, over fifty specific use container types, and over thirty distinct zones where work activities occur. During 1999, over five thousand transfers from one zone to another were conducted. Limits are placed on mass, material form and type, and container types for each zone. Ml material and containers are tracked using the Mass Tracking System (MTG). The MTG uses an Oracle database and numerous applications to manage the database. The database stores information specific to the process, including material composition and mass, container identification number and mass, transfer history, and the operators involved in each transfer. The process is controlled using written procedures which specify the zone, containers, and material involved in a task. Transferring a container from one zone to another is called a zone-to-zone transfer (ZZT). ZZTs consist of four distinct phases, select, request, identify, and completion

    The global burden of acute malnutrition among children remains high, and prevalence rates are highest in humanitarian contexts such as Niger. Unconditional cash transfers are increasingly used to prevent acute malnutrition in emergencies but lack a strong evidence base. In Niger, non-governmental organisations give unconditional cash transfers to the poorest households from June to September; the 'hunger gap'. However, rising admissions to feeding programmes from March/April suggest the intervention may be late. This cluster-randomised controlled trial will compare two types of unconditional cash transfer for 'very poor' households in 'vulnerable' villages defined and identified by the implementing organisation. 3,500 children (6-59 months) and 2,500 women (15-49 years) will be recruited exhaustively from households targeted for cash and from a random sample of non-recipient households in 40 villages in Tahoua district. Clusters of villages with a common cash distribution point will be assigned to either a control group which will receive the standard intervention (n = 10), or a modified intervention group (n = 10). The standard intervention is 32,500 FCFA/month for 4 months, June to September, given cash-in-hand to female representatives of 'very poor' households. The modified intervention is 21,500 FCFA/month for 5 months, April, May, July, August, September, and 22,500 FCFA in June, providing the same total amount. In both arms the recipient women attend an education session, women and children are screened and referred for acute malnutrition treatment, and the households receive nutrition supplements for children 6-23 months and pregnant and lactating women. The trial will evaluate whether the modified unconditional cash transfer leads to a reduction in acute malnutrition among children 6-59 months old compared to the standard intervention. The sample size provides power to detect a 5 percentage point difference in prevalence of acute malnutrition between trial

Our results show that a trade-off model best explains the level of a firm’s cash holdings in Australia. We find that 'transitory' excess cash firms earn significantly higher risk-adjusted returns compared to 'persistent' excess cash firms, suggesting that the market penalises firms that hoard cash.

  10. Assets Expropriation via Cash Dividends? Free Cash Flow or Tunneling

    Directory of Open Access Journals (Sweden)

    2010-06-01

    Full Text Available This study solves the dispute between the free cash flow and tunneling hypotheses in explaining the role of cash dividends on asset expropriation of the controlling shareholders in Chinese listed firms. Investors value more the cash dividends and the cash holdings of firms with lower ownership control than those of firms with higher ownership control. This is more consistent with the tunneling hypothesis. However, when investment opportunities are considered, the free cash flow hypothesis better explains firms' dividend policy. Investors value more the cash dividends of firms with fewer investment opportunities and higher probability of expropriation. This study indicates that investors are concerned with the potential asset expropriation through cash payouts, unless firms possess high growth opportunities.

  11. Taxable Cash Dividends

    DEFF Research Database (Denmark)

    Bechmann, Ken L.; Raaballe, Johannes

    Firms pay out cash using both dividends and share repurchases. In many aspects these two means are similar, but one important difference is that dividends are generally taxed more heavily than share repurchases. Nevertheless firms persist in paying out large amounts in dividends. This paper...... provides an explanation for this dividend puzzle by developing a class of signaling models violating the "single-crossing" property in which information about the quality of the firm is asymmetric between the management and the shareholders. In these models a high-quality firm can always signal its quality...... by using share repurchases only. However, in certain cases share repurchases become costlier on the margin for a high-quality firm than for a low-quality imitator. In such cases, the high-quality firm signals most cost efficiently by means of a combination of share repurchases and taxable cash dividends...

    The first criteria in boiling water systems design, such as boiling water reactors, is that no burnout in the core is allowed to exist under any conditions of the reactor operation either during steady state operation or during any of the several postulated accidental transients, such as sudden interruption of coolant flow in the reactor core (due to pump failure or blockage of fuel channel). The aim of the present work is to obtain a correlation for the critical heat flux based on a theoretical study where the mechanism of burn out and the related hydrodynamic and heat transfer equations are considered. 8 refs

    This report summarizes the research carried out at Florida International University's Hemispheric Center for Environmental Technology (FIU-HCET) for the fiscal year 1998 (FY98) under the Tank Focus Area (TFA) project ''Waste Conditioning for Tank Slurry Transfer.'' The objective of this project is to determine the effect of chemical and physical properties on the waste conditioning process and transfer. The focus of this research consisted in building a waste conditioning experimental facility to test different slurry simulants under different conditions, and analyzing their chemical and physical properties. This investigation would provide experimental data and analysis results that can make the tank waste conditioning process more efficient, improve the transfer system, and influence future modifications to the waste conditioning and transfer system. A waste conditioning experimental facility was built in order to test slurry simulants. The facility consists of a slurry vessel with several accessories for parameter control and sampling. The vessel also has a lid system with a shaft-mounted propeller connected to an air motor. In addition, a circulation system is connected to the slurry vessel for simulant cooling and heating. Experimental data collection and analysis of the chemical and physical properties of the tank slurry simulants has been emphasized. For this, one waste slurry simulant (Fernald) was developed, and another two simulants (SRS and Hanford) obtained from DOE sites were used. These simulants, composed of water, soluble metal salts, and insoluble solid particles, were used to represent the actual radioactive waste slurries from different DOE sites. The simulants' chemical and physical properties analyzed include density, viscosity, pH, settling rate, and volubility. These analyses were done to samples obtained from different experiments performed at room temperature but different mixing time and strength. The experimental results indicate that the

    Highlights: ► Investigates match properties of heat or mass transfer processes in HVAC system. ► Losses are caused by limited transfer ability, flow and parameter mismatching. ► Condition of flow matching is the same heat capacity of the fluids. ► Parameter matching is only reached along the saturation line in air–water system. ► Analytical solutions of heat and mass transfer resistance are derived. - Abstract: Sensible heat exchangers and coupled heat and mass transfer devices between humid air and water/desiccant are commonly used devices in air-conditioning systems. This paper focuses on the match properties of sensible heat transfer processes and coupled heat and mass transfer processes in an effort to understand the reasons for performance limitations in order to optimize system performance. Limited heat transfer capability and flow mismatching resulted in heat resistance of the sensible heat transfer process. Losses occurred during the heat and mass transfer processes due to limited transfer capability, flow mismatching, and parameter mismatching. Flow matching was achieved when the heat capacities of the fluids were identical, and parameter matching could only be reached along the saturation line in air–water systems or the iso-concentration line in air–desiccant systems. Analytical solutions of heat transfer resistance and mass transfer resistance were then derived. The heat and mass transfer process close to the saturation line is recommended, and heating sprayed water resulted in better humidification performance than heating inlet air in the air humidifier.

    We understand emergent quantum mechanics in the sense that quantum mechanics describes processes of physical emergence relating an assumed sub-quantum physics to macroscopic boundary conditions. The latter can be shown to entail top-down causation, in addition to usual bottom-up scenarios. With this example it is demonstrated that definitions of “realism” in the literature are simply too restrictive. A prevailing manner to define realism in quantum mechanics is in terms of pre-determination independent of the measurement. With our counter-example, which actually is ubiquitous in emergent, or self-organizing, systems, we argue for realism without pre-determination. We refer to earlier results of our group showing how the guiding equation of the de Broglie-Bohm interpretation can be derived from a theory with classical ingredients only. Essentially, this corresponds to a “quantum mechanics without wave functions” in ordinary 3-space, albeit with nonlocal correlations. This, then, leads to the central question of how to deal with the nonlocality problem in a relativistic setting. We here show that a basic argument discussing the allegedly paradox time ordering of events in EPR-type two-particle experiments falls short of taking into account the contextuality of the experimental setup. Consequently, we then discuss under which circumstances (i.e. physical premises) superluminal information transfer (but not signaling) may be compatible with a Lorentz-invariant theory. Finally, we argue that the impossibility of superluminal signaling - despite the presence of superluminal information transfer - is not the result of some sort of conspiracy (á la “Nature likes to hide”), but the consequence of the impossibility to exactly reproduce in repeated experimental runs a state's preparation, or of the no-cloning theorem, respectively.

  20. How much cash does your company need?

    Science.gov (United States)

    Passov, Richard

    2003-11-01

    In late 2001, the directors of Pfizer asked that very question. And with good reason. After its 2000 merger with rival Warner-Lambert, the New York-based pharmaceutical giant found itself sitting on a net cash position of $8 billion, which seemed extraordinarily conservative for a company whose products generated $30 billion in revenues. Most large companies with revenues that healthy would increase leverage, thereby unlocking tremendous value for shareholders. But knowledge-intensive companies like Pfizer, this author argues, are in a class apart. Because their largely intangible assets (like R&D) are highly volatile and cannot easily be valued, they are more vulnerable to financial distress than are firms with a preponderance of tangible assets. To insure against that risk, they need to maintain large positive cash balances. These companies' decisions to run large cash balances is one of the key reasons their shares sustain consistent premiums. Only by investing in their intangible assets can knowledge-based companies hope to preserve the value of those assets. A company that finds itself unable to do so because unfavorable market conditions reduce its operating cash flows will see its share price suffer almost as much as if it were to default on its debts. By the same token, with the right balance sheet, knowledge companies can profitably insure against the risk of failing to sustain value-added investments in difficult times. An optimal capital structure that calls for significant cash balances is certainly at odds with the results of a traditional capital structure analysis, the author demonstrates, but it explains the financial policies of many well-run companies, from Pfizer to Intel to ChevronTexaco.

  1. Cash efficiency for bank branches.

    2013-01-01

    Bank liquidity management has become a major issue during the financial crisis as liquidity shortages have intensified and have put pressure on banks to diversity and improve their liquidity sources. While a significant strand of the literature concentrates on wholesale liquidity generation and on the alternative to deposit funding, the management of an inventory of cash holdings within the banks' branches is also a relevant issue as any significant improvement in cash management at the bank distribution channels may have a positive effect in reducing liquidity tensions. In this paper, we propose a simple programme of cash efficiency for the banks' branches, very easy to implement, which conform to a set of instructions to be imposed from the bank to their branches. This model proves to significantly reduce cash holdings at branches thereby providing efficiency improvements in liquidity management. The methodology we propose is based on the definition of some stochastic processes combined with renewal processes, which capture the random elements of the cash flow, before applying suitable optimization programmes to all the costs involved in cash movements. The classical issue of the Transaction Demand for the Cash and some aspects of Inventory Theory are also present. Mathematics Subject Classification (2000) C02, C60, E50.

    Severe pitting has occurred in moderator heat exchangers tubed with Incoloy-800 in Pickering Nuclear Generating Station. The pitting originated on the cooling side (outside) of the tubes and perforation occurred in less than two years. It was known from corrosion testing at CRNL that Incoloy-800 was not susceptible to pitting in Lake Ontario water under isothermal conditions. Corrosion testing with heat transfer across the tube wall was carried out, and it was noted that severe pitting could occur under deposits formed on the tubes in silty Lake Ontario water. Subsequent testing, carried out in co-operation with Ontario Hydro Research Division, investigated the pitting resistance of other candidate tubing alloys: Incoloy-825, 904 L stainless steel, AL-6X, Inconel-625, 70:30 Cu:Ni, titanium, Sanicro-30 and Sanicro-28 1 . Of these, only titanium and Sanicro-28 have not suffered some degree of pitting attack in silt-containing Lake Ontario Water. In the absence of silt, and hence deposits, no pitting took place on any of the alloys tested

    Full Text Available This paper investigates issues involved in calibrating hydrological models against observed data when the aim of the modelling is to predict future runoff under different climatic conditions. To achieve this objective, we tested two hydrological models, DWBM and SIMHYD, using data from 30 unimpaired catchments in Australia which had at least 60 yr of daily precipitation, potential evapotranspiration (PET, and streamflow data. Nash-Sutcliffe efficiency (NSE, modified index of agreement (d1 and water balance error (WBE were used as performance criteria. We used a differential split-sample test to split up the data into 120 sub-periods and 4 different climatic sub-periods in order to assess how well the calibrated model could be transferred different periods. For each catchment, the models were calibrated for one sub-period and validated on the other three. Monte Carlo simulation was used to explore parameter stability compared to historic climatic variability. The chi-square test was used to measure the relationship between the distribution of the parameters and hydroclimatic variability. The results showed that the performance of the two hydrological models differed and depended on the model calibration. We found that if a hydrological model is set up to simulate runoff for a wet climate scenario then it should be calibrated on a wet segment of the historic record, and similarly a dry segment should be used for a dry climate scenario. The Monte Carlo simulation provides an effective and pragmatic approach to explore uncertainty and equifinality in hydrological model parameters. Some parameters of the hydrological models are shown to be significantly more sensitive to the choice of calibration periods. Our findings support the idea that when using conceptual hydrological models to assess future climate change impacts, a differential split-sample test and Monte Carlo simulation should be used to quantify uncertainties due to

The study is a cluster randomised controlled trial (non-blinded). PLA comprises women's groups that discuss, and form strategies about, nutrition in pregnancy, low birth weight and hygiene. Women receive up to 7 monthly transfers per pregnancy: cash is NPR 750 (~US$7) and food is 10 kg of fortified sweetened wheat-soya Super Cereal per month. The unit of randomisation is a rural village development committee (VDC) cluster (population 4000-9200, mean 6150) in southern Dhanusha or Mahottari districts. 80 VDCs are randomised to four arms using a participatory 'tombola' method. Twenty clusters each receive: PLA; PLA plus food; PLA plus cash; and standard care (control). Participants are (mostly Maithili-speaking) pregnant women identified from 8 weeks' gestation onwards, and their infants (target sample size 8880 birth weights). After pregnancy verification, mothers may be followed up in early and late pregnancy, within 72 h, after 42 days and within 22 months of birth. Outcomes pertain to the individual level. Primary outcomes include birth weight within 72 h of birth and infant weight-for-age Z-score measured cross-sectionally on children born of the study. Secondary outcomes include prevalence of LBW, eating behaviour and weight during pregnancy, maternal and newborn illness, preterm delivery, miscarriage, stillbirth or neonatal mortality, infant Z-scores for length-for-age and weight-for-length, head circumference, and postnatal maternal BMI and mid-upper arm circumference.

    2006-01-01

    This paper analyzes the role international transfers may play in international climate policy in consideration of the policy's ancillary benefits, such as air quality improvements. Ancillary benefits are especially important in many developing countries, while climate protection benefits or primary benefits play a minor role on the political agenda of these countries. In contrast, industrialized countries have a strong interest in combating climate change. These often neglected asymmetries between the developing and industrialized world affect the impacts of transfers. Interestingly, as we will show, the cost differentials between different environmental technologies among countries are the crucial prerequisite for the functioning of a transfer scheme and not the cost differentials in the execution of climate policy. This result has been overlooked by standard pure public good approaches

    Environmental transfer factors, as well as concentration and accumulation factors, have been increasingly used in environmental dosimetric models. These models are often the basis for decision-making processes concerning radiological protection. However, the uncertainties associated with measured and default values of transfer and concentration factors are usually not taken into account in the decision making processes. In addition, laboratory-based values for these factors do not necessarily agree with site-specific and species-specific transfer and concentration factors. Soil-to-plant transfer factors and water-to-aquatic-organisms concentration factors are not only time and concentration-dependent, but also species-and site-specific environment-dependent. These uncertainties and dependencies may make the decision-making process, based on models, quite a difficult exercise. The current work examines, as an example, the time-dependent variations in the accumulation of 226 Ra in zooplankton in a laboratory experiment as compared with the concentration factor measured in a natural environment. In addition, the work reviews differences in 228 Ra and 226 Ra concentration factors for several plant families measured in a highly radioactive environment. (author). 9 refs, 3 figs, 3 tabs

    The optimum heat transfer condition for a tubular type solar receiver was investigated for various receiver pipe size, heat transfer fluid, and design requirement and constraint(s). Heat transfer of a single plain receiver pipe exposed to concentrated solar energy was modelled along the flow path of the heat transfer fluid. Three different working fluids, molten salt, sodium, and supercritical carbon dioxide (sCO2) were considered in the case studies with different design conditions. The optimized ideal heat transfer condition was identified through fast iterative heat transfer calculations solving for all relevant radiation, conduction and convection heat transfers throughout the entire discretized tubular receiver. The ideal condition giving the best performance was obtained by finding the highest acceptable solar energy flux optimally distributed to meet different constraint(s), such as maximum allowable material temperature of receiver, maximum allowable film temperature of heat transfer fluid, and maximum allowable stress of receiver pipe material. The level of fluid side turbulence (represented by pressure drop in this study) was also optimized to give the highest net power production. As the outcome of the study gives information on the most ideal heat transfer condition, it can be used as a useful guideline for optimal design of a real receiver and solar field in a combined manner. The ideal heat transfer condition is especially important for high temperature tubular receivers (e.g. for supplying heat to high efficiency Brayton cycle turbines) where the system design and performance is tightly constrained by the receiver pipe material strength.

  14. Nucleate Boiling Heat Transfer Studied Under Reduced-Gravity Conditions

    2000-01-01

    Boiling is known to be a very efficient mode of heat transfer, and as such, it is employed in component cooling and in various energy-conversion systems. In space, boiling heat transfer may be used in thermal management, fluid handling and control, power systems, and on-orbit storage and supply systems for cryogenic propellants and life-support fluids. Recent interest in the exploration of Mars and other planets and in the concept of in situ resource utilization on the Martian and Lunar surfaces highlights the need to understand how gravity levels varying from the Earth's gravity to microgravity (1g = or > g/g(sub e) = or > 10(exp -6)g) affect boiling heat transfer. Because of the complex nature of the boiling process, no generalized prediction or procedure has been developed to describe the boiling heat transfer coefficient, particularly at reduced gravity levels. Recently, Professor Vijay K. Dhir of the University of California at Los Angeles proposed a novel building-block approach to investigate the boiling phenomena in low-gravity to microgravity environments. This approach experimentally investigates the complete process of bubble inception, growth, and departure for single bubbles formed at a well-defined and controllable nucleation site. Principal investigator Professor Vijay K.

    2017-11-01

    The purpose of this study is to discuss some problems which arise in heat or mass transfer in complex channels, with special reference to the spacer-filled channels adopted in membrane processes. Among the issues addressed are the consistent definition of local and mean heat or mass transfer coefficients; the influence of the wall boundary conditions; the influence of one-side versus two-side heat/mass transfer. Most of the results discussed were obtained by finite volume CFD simulations concerning heat transfer in Membrane Distillation or mass transfer in Electrodialysis and Reverse Electrodialysis, but many of the conclusions apply also to different processes involving geometrically complex channels

    Background Undernutrition during pregnancy leads to low birthweight, poor growth and inter-generational undernutrition. We did a non-blinded cluster-randomised controlled trial in the plains districts of Dhanusha and Mahottari, Nepal to assess the impact on birthweight and weight-for-age z-scores among children aged 0–16 months of community-based participatory learning and action (PLA) women’s groups, with and without food or cash transfers to pregnant women. Methods We randomly allocated 20 clusters per arm to four arms (average population/cluster = 6150). All consenting married women aged 10–49 years, who had not had tubal ligation and whose husbands had not had vasectomy, were monitored for missed menses. Between 29 Dec 2013 and 28 Feb 2015 we recruited 25,092 pregnant women to surveillance and interventions: PLA alone (n = 5626); PLA plus food (10 kg/month of fortified wheat-soya ‘Super Cereal’, n = 6884); PLA plus cash (NPR750≈US$7.5/month, n = 7272); control (existing government programmes, n = 5310). 539 PLA groups discussed and implemented strategies to improve low birthweight, nutrition in pregnancy and hand washing. Primary outcomes were birthweight within 72 hours of delivery and weight-for-age z-scores at endline (age 0–16 months). Only children born to permanent residents between 4 June 2014 and 20 June 2015 were eligible for intention to treat analyses (n = 10936), while in-migrating women and children born before interventions had been running for 16 weeks were excluded. Trial status: completed. Results In PLA plus food/cash arms, 94–97% of pregnant women attended groups and received a mean of four transfers over their pregnancies. In the PLA only arm, 49% of pregnant women attended groups. Due to unrest, the response rate for birthweight was low at 22% (n = 2087), but response rate for endline nutritional and dietary measures exceeded 83% (n = 9242). Compared to the control arm (n = 464), mean birthweight was significantly higher in

  5. Monitoring of Shadow Cash Flows Using Computer Modelling

    2018-03-01

    Full Text Available The computer simulation of economic systems is a promising tool in the development of the theory of the country’s economic security. We have examined the Russian banking legislation and synthesized judicial economic expertise. This has allowed to develop an algorithm for the investigation of the marker pattern of shadow cash flows. The authors’ algorithm of marker monitoring of cash flow consists of the following sequences. Firstly, we set the time of the first receipt of money and the first withdrawals. Secondly, we compare cash balance of an organization at the beginning of the period with the first withdrawals. Thirdly, under the given condition, the minimum value of interested money flow in these withdrawals is calculated. This value is characterized by the marker parameters and forms a table containing data on the cash flow, recipients and payers, spheres of their activity. And last, on the basis of this table, we build a graph of relationships between the subjects of the shadow economy. The graph’s vertices represent these subjects. The visual representation of the graph is a marker pattern of shadow cash flow. The practical importance of this algorithm is due to its applicability in the investigation of economic crimes both at the stage of intelligence operations, and when obtaining proofs of the brought criminal cases in the form of the conclusions of expertseconomists. In addition, marker patterns of shadow cash flows can describe the state of the shadow economy of a region as a whole including its dynamics. This expands its parameterization. The created database of the shadow flows of the economy can be also useful for the scientific community. On the basis of the received results, we have developed management decisions to create and administer the information resource of the Bank of Russia “Shadow economy of a region”. This information resource ensures tracking the marker trace of cash flow in the bank environment by the

    In everyday life, mental fatigue can be detrimental across many domains including driving, learning, and working. Given the importance of understanding and accounting for the deleterious effects of mental fatigue on behavior, a growing body of literature has studied the role of motivational and executive control processes in mental fatigue. In typical laboratory paradigms, participants complete a task that places demand on these self-control processes and are later given a subsequent task. Generally speaking, decrements to subsequent task performance are taken as evidence that the initial task created mental fatigue through the continued engagement of motivational and executive functions. Several models have been developed to account for negative transfer resulting from this "ego depletion." In the current study, we provide a brief literature review, specify current theoretical approaches to ego-depletion, and report an empirical test of current models of depletion. Across 4 experiments we found minimal evidence for executive control depletion along with strong evidence for motivation mediated ego depletion.

    Using the method of images, we examine the three boundary conditions commonly applied to the surface of a semi-infinite turbid medium. We find that the image-charge configurations of the partial-current and extrapolated-boundary conditions have the same dipole and quadrupole moments and that the two corresponding solutions to the diffusion equation are approximately equal. In the application of diffusion theory to frequency-domain photon-migration (FDPM) data, these two approaches yield values for the scattering and absorption coefficients that are equal to within 3%. Moreover, the two boundary conditions can be combined to yield a remarkably simple, accurate, and computationally fast method for extracting values for optical parameters from FDPM data. FDPM data were taken both at the surface and deep inside tissue phantoms, and the difference in data between the two geometries is striking. If one analyzes the surface data without accounting for the boundary, values deduced for the optical coefficients are in error by 50% or more. As expected, when aluminum foil was placed on the surface of a tissue phantom, phase and modulation data were closer to the results for an infinite-medium geometry. Raising the reflectivity of a tissue surface can, in principle, eliminate the effect of the boundary. However, we find that phase and modulation data are highly sensitive to the reflectivity in the range of 80--100%, and a minimum value of 98% is needed to mimic an infinite-medium geometry reliably. We conclude that noninvasive measurements of optically thick tissue require a rigorous treatment of the tissue boundary, and we suggest a unified partial-current--extrapolated boundary approach

    Highlights: • Compare turbine heat transfer correlations from different studies. • Compare heat transfer for a same turbine on-engine and on gas-stand. • Analyse heat transfer under steady and transient operating conditions. • Gas stand heat transfer correlations are transferrable to engine conditions. • Heat flows can be reversed compared to steady conditions during transients. - Abstract: Heat transfer is significant in turbochargers and a number of mathematical models have been proposed to account for the heat transfer, however these have predominantly been validated under steady flow conditions. A variable geometry turbocharger from a 2.2 L Diesel engine was studied, both on gas stand and on-engine, under steady and transient conditions. The results showed that heat transfer accounts for at least 20% of total enthalpy change in the turbine and significantly more at lower mechanical powers. A convective heat transfer correlation was derived from experimental measurements to account for heat transfer between the gases and the turbine housing and proved consistent with those published from other researchers. This relationship was subsequently shown to be consistent between engine and gas stand operation: using this correlation in a 1D gas dynamics simulation reduced the turbine outlet temperature error from 33 °C to 3 °C. Using the model under transient conditions highlighted the effect of housing thermal inertia. The peak transient heat flow was strongly linked to the dynamics of the turbine inlet temperature: for all increases, the peak heat flow was higher than under thermally stable conditions due to colder housing. For all decreases in gas temperature, the peak heat flow was lower and for temperature drops of more than 100 °C the heat flow was reversed during the transient

  16. An Efficient Topology for Wireless Power Transfer over a Wide Range of Loading Conditions

    Directory of Open Access Journals (Sweden)

    Tianqing Li

    2018-01-01

    Full Text Available Although an inductive power transfer (IPT system can transfer power efficiently in full-load conditions, its efficiency obviously decreases in light-load conditions. To solve this problem, based on a two-coil IPT system with a series-series compensation topology, a single-ended primary-inductor converter is introduced at the secondary side. By adjusting the set effective value of the current in the primary coil, the converter input voltage changes to maintain the equivalent input resistance of the converter in an optimal condition. The system can then transfer the power efficiently with the wide load conditions. Moreover, the system operates at a constant resonance frequency with a high power factor. Both the simulation and experimentation of a prototype with a 10 W IPT system demonstrate the effectiveness of the proposed topology for wireless power transfer.

    Full Text Available In this study, an integrated cash requirement forecasting and cash inventory optimization model is implemented in both the branch and automated teller machine (ATM networks of a mid-sized bank in Turkey to optimize the bank’s cash supply chain. The implemented model’s objective is to minimize the idle cash levels at both branches and ATMs without decreasing the customer service level (CSL by providing the correct amount of cash at the correct location and time. To the best of our knowledge, the model is the first integrated model in the literature to be applied to both ATMs and branches simultaneously. The results demonstrated that the integrated model dramatically decreased the idle cash levels at both branches and ATMs without degrading the availability of cash and hence customer satisfaction. An in-depth analysis of the results also indicated that the results were more remarkable for branches. The results also demonstrated that the utilization of various seasonal indices plays a very critical role in the forecasting of cash requirements for a bank. Another unique feature of the study is that the model is the first to include the recycling feature of ATMs. The results demonstrated that as a result of the inclusion of the deliberate seasonal indices in the forecasting model, the integrated cash optimization models can be used to estimate the cash requirements of recycling ATMs.

    Ginsberg, T.; Tutu, N.; Klages, J.; Schwarz, C.E.; Sanborn, Y.

    1983-02-01

    This paper presents recent experimental data for the quench-heat-transfer characteristics of superheated packed beds of spheres which were cooled, in separate experiments, by top- and bottom-flooding modes. Experiments were carried out with beds of 3-mm steel spheres of 330-mm height. The initial bed temperature was 810 K. The observed heat-transfer rates are strongly dependent on the mode of water injection. The results suggest that top-flood bed quench heat transfer is limited by the rate at which water can penetrate the bed under two-phase countercurrent-flow conditions. With bottom-reflood the heat-transfer rate is an order-of-magnitude greater than under top-flood conditions and appears to be limited by particle-to-fluid film boiling heat transfer

    A model has been developed to calculate the heat transfer coefficients from the fuel rods to the steam-droplet mixture typical of Boiling Water Reactors under Emergency Core Cooling System (ECCS) operation conditions during a postulated loss-of-coolant accident. The model includes the heat transfer by convection to the vapor, the radiation from the surfaces to both the water droplets and the vapor, and the effects of droplet evaporation. The combined convection and radiation heat transfer coefficient can be evaluated with respect to the characteristic droplet size. Calculations of the heat transfer coefficient based on the droplet sizes obtained from the existing literature are consistent with those determined empirically from the Full-Length-Emergency-Cooling-Heat-Transfer (FLECHT) program. The present model can also be used to assess the effects of geometrical distortions (or deviations from nominal dimensions) on the heat transfer to the cooling medium in a rod bundle

    To assess the effectiveness of an integrated early child development intervention, combining stimulation and micronutrient supplementation and delivered on a large scale in Colombia, for children's development, growth, and hemoglobin levels. Cluster randomized controlled trial, using a 2 × 2 factorial design, with municipalities assigned to one of four groups: psychosocial stimulation, micronutrient supplementation, combined intervention, or control. 96 municipalities in Colombia, located across eight of its 32 departments. 1420 children aged 12-24 months and their primary carers. Psychosocial stimulation (weekly home visits with play demonstrations), micronutrient sprinkles given daily, and both combined. All delivered by female community leaders for 18 months. Cognitive, receptive and expressive language, and fine and gross motor scores on the Bayley scales of infant development-III; height, weight, and hemoglobin levels measured at the baseline and end of intervention. Stimulation improved cognitive scores (adjusted for age, sex, testers, and baseline levels of outcomes) by 0.26 of a standard deviation (P=0.002). Stimulation also increased receptive language by 0.22 of a standard deviation (P=0.032). Micronutrient supplementation had no significant effect on any outcome and there was no interaction between the interventions. No intervention affected height, weight, or hemoglobin levels. Using the infrastructure of a national welfare program we implemented the integrated early child development intervention on a large scale and showed its potential for improving children's cognitive development. We found no effect of supplementation on developmental or health outcomes. Moreover, supplementation did not interact with stimulation. The implementation model for delivering stimulation suggests that it may serve as a promising blueprint for future policy on early childhood development.Trial registration Current Controlled trials ISRCTN18991160. © Attanasio et al 2014.

    Highlights: • Heat transfer characteristics and dryout for helically coiled tube are performed. • A boiling heat transfer tends to increase with a pressure increase. • Dryout occurs at high quality test conditions investigated. • Steiner–Taborek’s correlation is predicted well based on the experimental results. - Abstract: A helically coiled once-through steam generator has been used widely during the past several decades for small nuclear power reactors. The heat transfer characteristics and dryout conditions are important to optimal design a helically coiled steam generator. Various experiments with the helically coiled tubes are performed to investigate the heat transfer characteristics and occurrence condition of a dryout. For the investigated experimental conditions, Steiner–Taborek’s correlation is predicted reasonably based on the experimental results. The pressure effect is important for the boiling heat transfer correlation. A boiling heat transfer tends to increase with a pressure increase. However, it is not affected by the pressure change at a low power and low mass flow rate. Dryout occurs at high quality test conditions investigated because a liquid film on the wall exists owing to a centrifugal force of the helical coil

  5. Inflation, operating cycle, and cash holdings

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available A corporate cash-holding strategy is a trade-off between the costs and benefits of holding cash. At the macrolevel, firms are inclined to adjust and optimize their cash-holding strategies in response to changes in purchasing power due to inflation. At the microlevel, the operating cycle, which indicates the speed and turnover of corporate cash flow, also influences the corporate cash-holding strategy. Firms flexibly adjust their cash-holding strategies in response to changes in the internal and external environment, which is referred to as the cash adjustment strategy. We examine these predicted relationships using a sample of listed firms in China’s stock market over the 1998–2009 period. Consistent with our predictions, the empirical results indicate a significant negative association between cash holdings and the CPI, but the relationship is reversed when the CPI reaches a certain level. There is also a U-shaped relationship between operating cycle and cash holdings, and this relationship is similarly influenced by changes in the inflation level. In examining the macroeconomic environment and microlevel firm-specific characteristics simultaneously, our findings supplement the literature on firms’ cash-holding strategies and provide theoretical and practical implications.

    Social protection interventions, including cash grants and care provision have been shown to effectively reduce some negative impacts of the HIV epidemic on adolescents and families. Less is known about the role of social protection on younger HIV affected populations. This study explored the impact of cash grants on children's cognitive development. Additionally, we examined whether combined cash and care (operationalised as good parenting) was associated with improved cognitive outcomes. The sample included 854 children, aged 5 - 15, participating in community-based organisation (CBO) programmes for children affected by HIV in South Africa and Malawi. Data on child cognitive functioning were gathered by a combination of caregiver report and observer administered tests. Primary caregivers also reported on the economic situation of the family, cash receipt into the home, child and household HIV status. Parenting was measured on a 10 item scale with good parenting defined as a score of 8 or above. About half of families received cash (55%, n = 473), only 6% (n = 51) reported good parenting above the cut-off point but no cash, 18% (n = 151) received combined cash support and reported good parenting, and 21% (n = 179) had neither. Findings show that cash receipt was associated with enhanced child cognitive outcomes in a number of domains including verbal working memory, general cognitive functioning, and learning. Furthermore, cash plus good parenting provided an additive effect. Child HIV status had a moderating effect on the association between cash or/plus good parenting and cognitive outcomes. The association between cash and good parenting and child cognitive outcomes remained significant among both HIV positive and negative children, but overall the HIV negative group benefited more. This study shows the importance of cash transfers and good parenting on cognitive development of young children living in HIV affected environments. Our data clearly

    Full Text Available For measuring the efficiency of management of cash, cash holding is one of the most important financial decisions that the manager of the concerned organization, has to make in the organization. Basically, it is observed that the organization hold cash for future purposes is very negligible. If the organization invested cash in profitable securities then there is some flexibility but when it relates to the capital market holding cash is not advantageous. Generally two contradictory theories such as Trade-off theory and the Pecking order theory are considered for measuring the efficiency of cash management. In this study we generally observed measured the efficiency of Cash Management influenced by Cash Holding. We also measured whether cash holding of the organization is affected with the degree of financial leverage, size of the organization, investment and profitability. This study helps us to understand the influence of DFL, Investment and Size of the organization on Cash holding. Proper holding of cash in cash management can prevent the bankruptcy of any organization and also increases the efficiency of Cash or Liquidity management.

    The prevalence of acute malnutrition is often high in emergency-affected populations and is associated with elevated mortality risk and long-term health consequences. Increasingly, cash transfer programmes (CTP) are used instead of direct food aid as a nutritional intervention, but there is sparse evidence on their nutritional impact. We aim to understand whether CTP reduces acute malnutrition and its known risk factors. A non-randomised, cluster-controlled trial will assess the impact of an unconditional cash transfer of US$84 per month for 5 months, a single non-food items kit, and free piped water on the risk of acute malnutrition in children, aged 6-59 months. The study will take place in camps for internally displaced persons (IDP) in peri-urban Mogadishu, Somalia. A cluster will consist of one IDP camp and 10 camps will be allocated to receive the intervention based on vulnerability targeting criteria. The control camps will then be selected from the same geographical area. Needs assessment data indicates small differences in vulnerability between camps. In each trial arm, 120 households will be randomly sampled and two detailed household surveys will be implemented at baseline and 3 months after the initiation of the cash transfer. The survey questionnaire will cover risk factors for malnutrition including household expenditure, assets, food security, diet diversity, coping strategies, morbidity, WASH, and access to health care. A community surveillance system will collect monthly mid-upper arm circumference measurements from all children aged 6-59 months in the study clusters to assess the incidence of acute malnutrition over the duration of the intervention.

    Replacement of delivery settlement of futures contracts with cash settlement is frequently proposed to reduce the frequency of market manipulation. This article shows that it is always possible to design a delivery-settled futures contract that is less susceptible to cornering by a large long than any given cash-settled contract. Such a contract is more susceptible to manipulation by large shorts, however. Therefore, cash settlement does not uniformly dominate delivery settlement as a means o...

    Abeyrathne, Priyanka D; Lam, Joseph S

    2007-04-01

    A major hurdle in characterizing bacterial membrane proteins by Western blotting is the ineffectiveness of transferring these proteins from sodium dodecyl sulfate -- polyacrylamide gel electrophoresis (SDS-PAGE) gel onto nitrocellulose membrane, using standard Western blot buffers and electrophoretic conditions. In this study, we compared a number of modified Western blotting buffers and arrived at a composition designated as the SDS-PAGE-Urea Lysis buffer. The use of this buffer and specific conditions allowed the reproducible transfer of highly hydrophobic bacterial membrane proteins with 2-12 transmembrane-spanning segments as well as soluble proteins onto nitrocellulose membranes. This method should be broadly applicable for immunochemical studies of other membrane proteins.

    The square-lattice eight-vertex model with vertex weights a, b, c, d obeying the relation (a^2+ab)(b^2+ab) = (c^2+ab)(d^2+ab) and periodic boundary conditions is considered. It is shown that the transfer matrix of the model for L  =  2n  +  1 vertical lines and periodic boundary conditions along the horizontal direction possesses the doubly degenerate eigenvalue \\Thetan = (a+b){\\hspace{0pt}}2n+1 . This proves a conjecture by Stroganov from 2001. The proof uses the supersymmetry of a related XYZ spin-chain Hamiltonian. The eigenstates of the transfer matrix corresponding to \\Thetan are shown to be the ground states of the spin-chain Hamiltonian. Moreover, for positive vertex weights \\Thetan is the largest eigenvalue of the transfer matrix.

    2008-01-01

    The present paper describes the heat transfer in intermediate heat exchangers (IHXs) of liquid metal cooled fast reactors when flow rate is low such as a natural circulation condition. Although empirical correlations of heat transfer coefficients for IHX were derived using test data at the fast reactor 'Monju' and 'Joyo' and also at the 50 MW steam generator facility, the heat transfer coefficient was very low compared to the well known correlation for liquid metals proposed by Seban-Shimazaki. The heat conduction in IHX was discussed as a possible cause of the low Nusselt number. As a result, the heat conduction is not significant under the natural circulation condition, and the heat conduction term in the energy equation can be neglected in the one-dimensional plant dynamics calculation.

    1985-01-01

    Heat flux plates are used for measuring rates of heat transfer through surfaces under steady state and transient conditions. Their usual construction is to have a resistive layer bounded by thermopiles and an exterior layer for protection. If properly designed and constructed a linear relationship between the thermopile generated voltage and heat flux results and calibration under steady state conditions is straight forward. Under transient conditions however the voltage output from a heat flux plate cannot instantaneously follow the heat flux because of the thermal capacitance of the plate and the resulting time lag. In order to properly interpret the output of a heat flux plate used under transient conditions a simple heat transfer model was constructed and tested. (author)

  7. Influences of buoyancy and thermal boundary conditions on heat transfer with naturally-induced flow

    Jackson, J.D.; Li, J.

    2002-01-01

    A fundamental study is reported of heat transfer from a vertical heated tube to air which is induced naturally upwards through it by the action of buoyancy. Measurements of local heat transfer coefficient were made using a specially designed computer-controlled power supply and measurement system for conditions of uniform wall temperature and uniform wall heat flux. The effectiveness of heat transfer proved to be much lower than for conditions of forced convection. It was found that the results could be correlated satisfactorily when presented in terms of dimensionless parameters similar to those used for free convection heat transfer from vertical surfaces provided that the heat transfer coefficients were evaluated using local fluid bulk temperature calculated utilising the measured values of flow rate induced through the system. Additional experiments were performed' with pumped flow. These covered the entire mixed convection region. It was found that the data for naturally-induced flow mapped onto the pumped flow data when presented in terms of Nusselt number ratio (mixed to forced) and buoyancy parameter. Computational simulations of the experiments were performed using an advanced computer code which incorporated a buoyancy-influenced, variable property, developing wall shear flow formulation and a low Reynolds number k-ε turbulence model. These reproduced observed behaviour quite well. (author)

    Gap heat transfer between fuel pellet and cladding have a large influence on the LWR fuel behaviors under reactivity initiated accident (RIA) conditions. The objective of the present study is to investigate the effects of gap heat transfer on RIA fuel behaviors based on the results of the gap-gas parameter tests in NSRR and on their analysis with NSR-77 code. Through this study, transient variations of gap heat transfer, the effects of the gap heat transfer on fuel thermal behaviors and on fuel failure, effects of pellet-cladding sticking by eutectic formation, and the effects of cladding collapse under high external pressure have been clearified. The studies have also been performed on the applicability and its limit of modified Ross and Stoute equation which is extensively utilized to evaluate the gap heat transfer coefficient in the present fuel behavior codes. The method to evaluate the gap conductance to the conditions beyond the applicability limit of the Ross and Stoute equation has also been proposed. (author)

    Directory of Open Access Journals (Sweden)

    Maret Güldenkoh

    2014-12-01

    Full Text Available Family enterprise is a business entity that belongs to the family. In Estonia the concept of family business, family entrepreneur, or family enterprise has not been defined in legislation. The concepts of business and enterprise have been defined in several pieces of law with some dissensions in their interpretations, however. Differences in legal definitions become obvious when transferring a business. The aim of the article is to assess the legislative conditions of family enterprises in Estonia. Family enterprises can be transferred either by way of transferring the holding status or by transferring the enterprise. Holding can be transferred in companies; a sole proprietor should transfer the business entity either as a whole or transfer the business entity into a company to have a holding there. Family businesses operating as sole proprietors may incur tax liability by transferring the family enterprise. The paper outlines special features of transferring enterprises, including family enterprises in Estonia. Business transfers have been few and there is no unambiguous practice in this sphere. Transfer of family enterprises is identified with transfer of enterprises; differences arise when family business has been registered as a sole proprietor. The paper provides a brief description of the differences in transferring enterprises, including family enterprises in Estonia. A purpose was to evaluate the legal environment of transferring family enterprises. In Estonia guidelines should be formulated for transferring the business of a self-employed family member and legal regulations should be introduced to avoid ill-intentioned transfer of enterprises.

    2015-01-01

    The present paper describes the liquid metal heat transfer in heat exchangers under low flow rate conditions. Measured data from some experiments indicate that heat transfer coefficients of liquid metals at very low Péclet number are much lower than what are predicted by the well-known empirical relations. The cause of this phenomenon was not fully understood for many years. In the present study, one countercurrent-type heat exchanger is analyzed using three, separated countercurrent heat exchanger models: one is a heat exchanger model in the tube bank region, while the upper and lower plena are modeled as two heat exchangers with a single heat transfer tube. In all three heat exchangers, the same empirical correlation is used in the heat transfer calculation on the tube and the shell sides. The Nusselt number, as a function of the Péclet number, calculated from measured temperature and flow rate data in a 50 MW experimental facility was correctly reproduced by the calculation result, when the calculated result is processed in the same way as the experiment. Finally, it is clarified that the deviation is a superficial phenomenon which is caused by the heat transfer in the plena of the heat exchanger. (author)

Traditional heat transfer fluids with order of nanometer sized particles (1–100 nm) suspended in them are termed as nanofluids. Nanofluids have been proved as better heat transfer fluids despite of various contradictions in results by different research groups. The aim of this article is to review and summarize the recent experimental and theoretical studies on convective heat transfer in heat exchangers using constant heat flux boundary condition. The use of different types of nanoparticles with different base fluids by different research groups has been presented and compared. Further an overview of experimental results about heat transfer abilities of hybrid nanofluids from available literature sources is also presented. Finally, the challenges and future directions in which research can be further progress are discussed.

We show that firms' marginal value of cash (MVC) affects the mix of external and internal finance used to absorb fluctuations in cash flows; in particular, high-MVC firms employ substantially more external finance on the margin. Linking firms to their main bank, we find that shocks to bank finance affect firms' trade-offs and have real effects in high-MVC firms, making investment more sensitiv...

  19. Stock Liquidity and Corporate Cash Holdings: Feedback and the Cash as Ammunition Hypothesis

    OpenAIRE

    Nyborg, Kjell G; Wang, Zexi

    2013-01-01

    The paper contributes to the literature on corporate cash holdings by showing that there is a financial markets channel that affects corporations’ cash holdings. Leaning on the literature on stock price feedback to firm fundamentals, we advance the hypothesis that firms with more liquid stocks hold more cash, ceteris paribus, as ammunition to defend against negative cascades or stimulate positive ones. This contrasts with an alternative view that firms with more liquid stocks are less financi...

    There is a 64 billion dollar annual unattended cash transaction business in the US with 10 to 20 million daily transactions. Even small problems with the machine readability of banknotes can quickly become a major problem to the machine manufacturer and consumer. Traditional note designs incorporate overt security features for visual validation by the public. Many of these features such as fine line engraving, microprinting and watermarks are unsuitable as machine readable features in low cost note acceptors. Current machine readable features, mostly covert, were designed and implemented with the central banks in mind. These features are only usable by the banks large, high speed currency sorting and validation equipment. New note designs should consider and provide for low cost not acceptors, implementing features developed for inexpensive sensing technologies. Machine readable features are only as good as their consistency. Quality of security features as well as that of the overall printing process must be maintained to ensure reliable and secure operation of note readers. Variations in printing and of the components used to make the note are one of the major causes of poor performance in low cost note acceptors. The involvement of machine manufacturers in new currency designs will aid note producers in the design of a note that is machine friendly, helping to secure the acceptance of the note by the public as well as acting asa deterrent to fraud.

    Full Text Available It is known the fact that often the entities offer to staff or third parties certain amounts of money, in order to make payments for the entities, such sums being registered differently in the accounting as cash advances. In the case in which the advances are offered in a foreign currency, there is the problem of the exchange rate used when justifying the advance, for the conversion in lei of payments that were carried out. In this article we wanted to signal the effect that the exchange rate, used in the assessment for reflecting in the accounting operations concerning cash advance reimbursements in a foreign currency, has on the information presented in the financial statement. Therewith, we signal some aspects from the content of the accounting regulations, with reference at defining the cash advances, meaning, and the presentation in the balance sheet of cash advances, which, in our opinion, impose clarifications.

  3. Cash flow forecast for South African firms

    Directory of Open Access Journals (Sweden)

    Yun Li

    2015-06-01

    Full Text Available This paper applies models in the extant literature that have been used to forecast operating cash flows to predict the cash flows of South African firms listed on the Johannesburg Stock Exchange. Out-of-sample performance is examined for each model and compared between them. The reported results show that some accrual terms, i.e. depreciation and changes in inventory do not enhance cash flow prediction for the average South African firm in contrast to the reported results of studies in USA and Australia. Inclusion of more explanatory variables does not necessarily improve the models, according to the out-of-sample results. The paper proposes the application of moving average model in panel data, and vector regressive model for multi-period-ahead prediction of cash flows for South Africa firms.

    2011-01-01

    Experiments have been conducted to study the heat transfer characteristics of single-phase forced circulation when the test tube was under different marine conditions. The experiments measured the wall temperature of test tube to calculate the heat transfer coefficients at different circumferential places. When the test tube was under inclined conditions, the heat transfer coefficient increased at downside and decreased at upside of test tube because of buoyancy effect. When the test tube was under rolling conditions, the heat transfer coefficients fluctuated with the rolling motions, and the Coriolis force dominated the heat transfer fluctuation during the rolling motion. CFD method was used to simulate the heat transfer phenomena under marine conditions, and the results were accord to the experimental phenomena. (authors)

  7. A mathematical model for localized corrosion in steam generator crevices under heat transfer conditions

    1995-01-01

    A predictive and self-consistent mathematical model has been developed to describe the localized corrosion in steam generators. The model recognizes that the internal and external environment are coupled by the need to conserve charge in the system. Thus, solution of Laplace's equation for the external environment (outside the crevice) provides the boundary condition for the electric potential at the crevice mouth, which is needed for solving the system of mass transfer equations for the internal environment (inside the crevice). Mass transfer by diffusion, ion migration, and convection was considered. Heat and momentum transfer equations are solved simultaneously, with the mass balance equation for each species and the condition of electroneutrality inside the cavity being considered. The model takes into account the porosity and tortuosity in the corrosion product deposit in the crevice. The homogeneous chemical reactions (hydrolysis of the products of the anodic reaction and the autoprotolysis of water) are included in the model. The model, in this preliminary form predicts the solution chemistry, potential drop, and temperature distribution inside the crevice. An order of magnitude estimate of the crevice corrosion rate also obtained. At this point, the model predicts only the steady state solution, but it is recognized that a steady state may not exist under normal conditions

    2015-01-01

    Highlights: • Experimental research has been made on the membrane air-conditioning system. • We develop mass transfer models for the membrane regeneration process. • The paper exposes the actual performance of the system. • Increase of membrane pairs improves the performance. - Abstract: Absorption air-conditioning system has great advantages in energy conservation and environmental protection. To improve the performance of the traditional system, the membrane regeneration absorption system was proposed. Its COP could approach 6 by regenerating absorbent solution with the ion exchange membranes. However, the theoretical conclusion has not been supported by the experiment. This paper presents the experimental research of the membrane regeneration process. It has investigated the mass transfer process, energy efficiency and actual performance under different working conditions. Based on that, a mass transfer model has been developed and the influences of some key parameters have been exposed. It found the regeneration performance is mainly influenced by the current intensity. The calculation results with the model agree well the experimental data. The actual efficiency was lower than 50%, caused by energy loss in heat and electrochemical reactions. The actual COP is between 1 and 3, lower current intensity and more membrane pairs could improve it.

  9. A test facility for heat transfer, pressure drop and stability studies under supercritical conditions

    2013-02-01

    Supercritical water (SCW) exhibits excellent heat transfer characteristics and high volumetric expansion coefficient (hence high mass flow rates in natural circulation systems) near pseudo-critical temperature. SCW is being considered as a coolant in some advanced nuclear reactor designs on account of its potential to offer high thermal efficiency, compact size, elimination of steam generator, separator and dryer, making it economically competitive. The elimination of phase change results in elimination of the Critical Heat Flux (CHF) phenomenon. Cooling a reactor at full power with natural instead of forced circulation is generally considered as enhancement of passive safety. In view of this, it is essential to study natural circulation, heat transfer and pressure drop characteristics of supercritical fluids. Carbon-dioxide can be considered to be a good simulant of water for natural circulation at supercritical conditions since the density and viscosity variation of carbon-dioxide follows a parallel curve as that of water at supercritical conditions. Hence, a supercritical pressure natural circulation loop (SPNCL) has been set up in Hall-7, BARC to investigate the heat transfer, pressure drop and stability characteristics of supercritical carbon-dioxide under natural circulation conditions. The details of the experimental facility are presented in this report. (author)

    The purpose of the study is comparative investigation of low-temperature phenomena of charge and heat transfer in p-PbTe monocrystals grown by the method of oriented crystallization under zero-g conditions as well as under terrestrial conditions at identical technological regimes. Investigation of thermal conductivity a strong magnetic field permits to separate lattice and electron thermal conductivity components, the latter constituting 6% of total thermal conductivity. Therefore the predominant contribution to kappa(T) is made by the lattice thermal conductivity which turned to be close by value for both samples. This points to identical character of structural perfection of p-PbTe investigated monocrystals

    An investigation of the behavior of the power-conditioning system as a whole is a necessity to ensure the integrity of the aggregate system in the case of space applications. An approach for conducting such an investigation is considered. A description is given of the application of a general digital analog simulator program to the study of an aggregate power-conditioning system which is being developed for use on the International Ultraviolet Explorer spacecraft. The function of the direct energy transfer system studied involves a coupling of a solar array through a main distribution bus to the spacecraft electrical loads.

  12. Heat and mass transfer boundary conditions at the surface of a heated sessile droplet

    Science.gov (United States)

    Ljung, Anna-Lena; Lundström, T. Staffan

    2017-12-01

    This work numerically investigates how the boundary conditions of a heated sessile water droplet should be defined in order to include effects of both ambient and internal flow. Significance of water vapor, Marangoni convection, separate simulations of the external and internal flow, and influence of contact angle throughout drying is studied. The quasi-steady simulations are carried out with Computational Fluid Dynamics and conduction, natural convection and Marangoni convection are accounted for inside the droplet. For the studied conditions, a noticeable effect of buoyancy due to evaporation is observed. Hence, the inclusion of moisture increases the maximum velocities in the external flow. Marangoni convection will, in its turn, increase the velocity within the droplet with up to three orders of magnitude. Results furthermore show that the internal and ambient flow can be simulated separately for the conditions studied, and the accuracy is improved if the internal temperature gradient is low, e.g. if Marangoni convection is present. Simultaneous simulations of the domains are however preferred at high plate temperatures if both internal and external flows are dominated by buoyancy and natural convection. The importance of a spatially resolved heat and mass transfer boundary condition is, in its turn, increased if the internal velocity is small or if there is a large variation of the transfer coefficients at the surface. Finally, the results indicate that when the internal convective heat transport is small, a rather constant evaporation rate may be obtained throughout the drying at certain conditions.

  14. Heat Transfer Enhancement of the Air-Cooling Tower with Rotating Wind Deflectors under Crosswind Conditions

    2018-04-01

    Full Text Available To investigate the effect of wind deflectors on air flow and heat transfer performance of an air-cooling tower under crosswind conditions, an experimental system based on a surface condenser aluminum exchanger-type indirect air-cooling tower is established at a 1:100 proportional reduction. A 3-D computational fluid dynamics simulation model is built to study the air flow and temperature fields. The air flow rate into the cooling tower and the heat transfer rate of the radiators are used to evaluate cooling performance. Rotating wind deflectors are adopted to reduce the influence of crosswind on the cooling tower performance. The effects of the rotating wind deflectors on the thermal-hydraulic characteristics of the air-cooling tower under different environmental crosswind speeds are studied. Results indicate that the wind direction in the tower reverses as the rotating speed of the wind deflectors increases. The thermal performance of an air-cooling tower under crosswind conditions can be improved by using rotating wind deflectors. The heat transfer rate of a cooling tower with eight wind deflectors begins to increase when the rotating speed exceeds 2 r/min.

  15. Multiple determinants of transfer of evaluative function after conditioning with free-operant schedules of reinforcement.

    Dack, Charlotte; Reed, Phil; McHugh, Louise

    2010-11-01

    The aim of the four present experiments was to explore how different schedules of reinforcement influence schedule-induced behavior, their impact on evaluative ratings given to conditioned stimuli associated with each schedule through evaluative conditioning, and the transfer of these evaluations through derived stimulus networks. Experiment 1 compared two contrasting response reinforcement rules (variable ratio [VR], variable interval [VI]). Experiment 2 varied the response to reinforcement rule between two schedules but equated the outcome to response rate (differential reinforcement of high rate [DRH] vs. VR). Experiment 3 compared molar and molecular aspects of contingencies of reinforcement (tandem VIVR vs. tandem VRVI). Finally, Experiment 4 employed schedules that induced low rates of responding to determine whether, under these circumstances, responses were more sensitive to the molecular aspects of a schedule (differential reinforcement of low rate [DRL] vs. VI). The findings suggest that the transfer of evaluative functions is determined mainly by differences in response rate between the schedules and the molar aspects of the schedules. However, when neither schedule was based on a strong response reinforcement rule, the transfer of evaluative judgments came under the control of the molecular aspects of the schedule.

    The development of an experimental data bank on heat transfer orisis under stationary conditions is discussed. The work is being carried out under the auspices of CMEA in compliance with the resolution of CMEA countries experts meetinq in January 1981 held in Moscow. The data bank is supposed to be formed as a sequential set of available experimental data on the regimes with heat-transfer crisis, recorded on a standard magnetic tape for ES or IBM comuter family. All operations with the bank are to be performed via the computer. Recommendations are given to what the record structure should be used and an example of a code is suggested for a user to extract data from the bank in accordance with various criteria. At the present time parameters of more than 12000 experimental regimes are prepared for the bank and some 3000 more are being processed [ru

    1990-01-01

    To provide a basis for estimating the effectiveness of various treatments in reducing radiocaesium transfer to vegetation and grazing animals in upland ecosystems, studies have been undertaken to determine interactions between radiocaesium transfer and that of analogous elements (e.g. Rb, K) and the effects of various inorganic fertilizers (lime, NPK at different rates). Laboratory results demonstrated Rb and K (at equivalent ionic concentrations) tended to reduce radiocaesium concentrations in vegetation. These effects were highly dependent on the particular combination of plant species and soil conditions. Field investigations showed that potassium reduced radiocaesium concentrations in vegetation only very slightly. Though statistically significant, this effect was insufficient a basis to recommend the use of potassium treatments to ameliorate the effects of deposited radiocaesium. Studies at sites with a known history of land management prior to, or after, the Chernobyl accident show the effect of liming, ancient drainage, and application of organic and inorganic fertilizers.

    A microcomputer based program called Heat Transfer Prediction Software (HTPS) has been developed. It calculates the heat transfer for the tube and bundle geometries for steady state and transient conditions. This program is capable of providing the best estimated of the hot pin temperatures during slow transients for 37- and 28-element CANDU type fuel bundles. The program is designed for an IBM-PC AT/XT (or IBM-PC compatible computer) equipped with a Math Co-processor. The following input parameters are required: pressure, mass flux, hydraulic diameter, and quality. For the steady state case, the critical heat flux (CHF), the critical heat flux temperature, the minimum film boiling temperature, and the minimum film boiling heat flux are the primary outputs. With either the surface heat flux or wall temperature specified, the program determines the heat transfer regime and calculates the surface heat flux, wall temperatures and heat transfer coefficient. For the slow transient case, the pressure, mass flux, quality, and volumetric heat generation rate are the time dependent input parameters required to calculate the hot pin sheath temperatures and surface heat fluxes. A simple routine for generating properties has been developed for light water to support the above program. It contains correlations that have been verified for pressures ranging from 0.6kPa to 30 MPa, and temperatures up to 1100 degrees Celcius. The thermodynamic and transport properties that can be generated from this routine are: density, specific volume, enthalpy, specific heat capacity, conductivity, viscosity, surface tension and Prandtl number for saturated liquid, saturated vapour, subcooled liquid for superheated vapour. A software for predicting flow regime has also been developed. It determines the flow pattern at specific flow conditions, and provides a correction factor for calculating the CHF during partially stratified horizontal flow.

    Full Text Available The FASB and the IASB recently released a joint Discussion Paper “Preliminary Views on FinancialStatement Presentation” (International Accounting Standards Board 2008, which contains a major proposalrequiring companies to report operating cash flows using the direct method and it also requires that theindirect method of calculating operating cash flows be disclosed in the notes. This is a departure from currentrules and has generated considerable debate among respondents’ comment letters on the Discussion Paper.This paper adds to this debate by providing some evidence as to the size of the gap users confront when usingthe indirect method to estimate the major operating cash flow elements, such as cash collected fromcustomers and cash paid to suppliers. Using a sample of Australian companies which reported operating cashflows using the direct method, and presented the indirect method in the notes, we find significant differencesbetween reported and estimated figures for both cash collected from customers and cash paid to suppliers.These findings support the discussion paper’s proposal that companies be required to report cash flows usingboth the direct and indirect methods.

Panel data model was used to observe the research. The sample of this study was 247 companies listed in Indonesia Stock Exchange for the years 2008-2010. The results show that modified audit opinion, except unqualified opinion with explanatory paragraph about going concern, did not affect borrowing cash flow because audit opinion was not the only consideration for granting credit by creditors. Companies receiving modified audit opinion were proven using more operating cash flow for investing shown in investment cash flow, especially companies receiving unqualified opinion with explanatory paragraph about going concern.

  2. Conditional transfer of emission rights. Not a good idea; Voorwaardelijke overdraagbaarheid emissierechten. Geen goede gedachte

    2004-02-01

    The Dutch government embraces the idea that trading of emission allowances is a useful way of reducing the emission of harmful gasses. In the current plans to amend the Environmental Management Act, however, the legislator has chosen for a system where allowances may only be transferred in accordance with strict conditions. These conditions do not provide a legal framework for an efficient emission allowances trading market. As a result, Dutch industry will potentially be placed in an unfavourable position. The legislator, it is suggested, should opt for fully transferable allowances. It is crucial that an efficient international market for trading in allowances is established. This means that it should be possible to trade these allowances easily, without excessive legal restrictions. The aim of the legislator is to prevent extreme situations in this market. While its concerns are valid, however, the legislator has missed the mark by choosing a system whereby transfer of allowances is subject to excessive conditions. The legal consequence of not fulfilling one or more of the conditions during the sale is that the allowance will not be legally transferred, and the seller will remain the proprietor of the allowance, without either the seller or the buyer being aware of the situation. It is clear that this would be an unworkable situation as it would not be possible from a practical angle to simply and quickly check previous transactions. Overall, this would result in high transactions costs, which in turn would be a barrier to an efficient market. In summary, an efficient market in emission allowances seems to be an illusion if the transfer of allowances are subject to such conditions as are presently envisaged by the law. It is suggested that the legislator can reach its goals by dropping the conditions for transfers and by supervising the transactions through administrative and criminal procedures instead. This will not affect the owners-hip of emission allowances

    Lovas, R.G.; Pal, K.F.

    1984-01-01

    The orthogonality-condition model (OCM), as an approximation method for calculating the overlap and potential overlap functions involved in the form factor of transfer reactions, is tested against microscopic cluster calculations for the 7 Li=α+t system. The OCM overlap and potential overlap turned out to depend strongly on the OCM potential although the potentials are chosen so as to produce the same asymptotic phase. Excellent approximations to microscopic overlaps and potential overlaps are, however, obtained by optimizing the OCM potential so that the OCM may reproduce the microscopic energy surface. This way the dependence on the OCM potential is traced back to the underlying nucleon-nucleon force. (author)

  5. Condition monitoring of steam generator by estimating the overall heat transfer coefficient

    Furusawa, Hiroaki; Gofuku, Akio

    2013-01-01

    This study develops a technique for monitoring in on-line the state of the steam generator of the fast-breeder reactor (FBR) “Monju”. Because the FBR uses liquid sodium as coolant, it is necessary to handle liquid sodium with caution due to its chemical characteristics. The steam generator generates steam by the heat of secondary sodium coolant. The sodium-water reaction may happen if a pinhole or crack occurs at the thin metal tube wall that separates the secondary sodium coolant and water/steam. Therefore, it is very important to detect an anomaly of the wall of heat transfer tubes at an early stage. This study aims at developing an on-line condition monitoring technique of the steam generator by estimating overall heat transfer coefficient from process signals. This paper describes simplified mathematical models of superheater and evaporator to estimate the overall heat transfer coefficient and a technique to diagnose the state of the steam generator. The applicability of the technique is confirmed by several estimations using simulated process signals with artificial noises. The results of the estimations show that the developed technique can detect the occurrence of an anomaly. (author)

    Full Text Available Cash management products are in the function of promotion of the company's business, i.e. of liquidity management. The objective of this work is to determine the level of development of the Cash Management products in Serbia and their impact on the profitability and cost optimisation of a bank. Domestic banks established with foreign capital, primarily from Austria and Italy, were the first to introduce the initial contemporary Cash Management Products by the end of 2002, thanks to the development of electronic banking and relocation of the domestic payment transfers into the business banks. In addition, the analysis will show that banks with a clear focus on cooperation with the corporate clients are continuously developing this group of products in Serbia (Raiffeisen Bank, UniCredit Bank, Banca Intesa, Erste Bank. The research covers parallel presentation of development of the Cash Management products both of the domestic banks and their head offices abroad by the end of the year 2009 and the year 2012. The results of conducted research point out at the fact that the domestic banks established with the Italian capital (Banca Intesa and UniCredit Bank have taken over the leading role in the introduction of the new and more modern Cash Management products thanks to the good sector of information technology that is present in Serbia.

  7. Disrupting astrocyte–neuron lactate transfer persistently reduces conditioned responses to cocaine

    KAUST Repository

    2015-10-27

    A central problem in the treatment of drug addiction is the high risk of relapse often precipitated by drug-associated cues. The transfer of glycogen-derived lactate from astrocytes to neurons is required for long-term memory. Whereas blockade of drug memory reconsolidation represents a potential therapeutic strategy, the role of astrocyte–neuron lactate transport in long-term conditioning has received little attention. By infusing an inhibitor of glycogen phosphorylase into the basolateral amygdala of rats, we report that disruption of astrocyte-derived lactate not only transiently impaired the acquisition of a cocaine-induced conditioned place preference but also persistently disrupted an established conditioning. The drug memory was rescued by L-Lactate co-administration through a mechanism requiring the synaptic plasticity-related transcription factor Zif268 and extracellular signal-regulated kinase (ERK) signalling pathway but not the brain-derived neurotrophic factor (Bdnf). The long-term amnesia induced by glycogenolysis inhibition and the concomitant decreased expression of phospho-ERK were both restored with L-Lactate co-administration.

    Full Text Available Vacuum, cabinet and open air drying of pomegranate fruit leather were carried out at various drying conditions to monitor the drying kinetics together with bionutrient degradation of the product. Drying curves exhibited first order drying kinetics and effective moisture diffusivity values varied between 3.1 × 10−9 and 52.6 × 10−9 m2/s. The temperature dependence of the effective moisture diffusivity was satisfactorily described by an Arrhenius-type relationship. Drying conditions, product thickness and operation temperature had various effects on drying rate and final quality of the product. In terms of drying kinetics and final quality of product, vacuum drying had higher drying rate with higher conservation of phenolic, anthocyanin and ascorbic acid that is connected to faster drying condition and oxygen deficient medium. Anthocyanin content was significantly affected by drying method, drying temperature and product thickness. Scatter plot using principle component analysis enabled better understanding of moisture transfer rate and anthocyanin change under various drying conditions.

    A central problem in the treatment of drug addiction is the high risk of relapse often precipitated by drug-associated cues. The transfer of glycogen-derived lactate from astrocytes to neurons is required for long-term memory. Whereas blockade of drug memory reconsolidation represents a potential therapeutic strategy, the role of astrocyte–neuron lactate transport in long-term conditioning has received little attention. By infusing an inhibitor of glycogen phosphorylase into the basolateral amygdala of rats, we report that disruption of astrocyte-derived lactate not only transiently impaired the acquisition of a cocaine-induced conditioned place preference but also persistently disrupted an established conditioning. The drug memory was rescued by L-Lactate co-administration through a mechanism requiring the synaptic plasticity-related transcription factor Zif268 and extracellular signal-regulated kinase (ERK) signalling pathway but not the brain-derived neurotrophic factor (Bdnf). The long-term amnesia induced by glycogenolysis inhibition and the concomitant decreased expression of phospho-ERK were both restored with L-Lactate co-administration. These findings reveal a critical role for astrocyte-derived lactate in positive memory formation and highlight a novel amygdala-dependent reconsolidation process, whose disruption may offer a novel therapeutic target to reduce the long-lasting conditioned responses to cocaine.

    This work has a twofold aim: (a) to analyze an alternative approach for computing the conditional Lyapunov exponent (λcmax) aiming to evaluate the synchronization stability between nonlinear oscillators without solving the classical variational equations for the synchronization error dynamical system. In this first framework, an analytic reference value for λcmax is also provided in the context of Duffing master-slave scenario and precisely evaluated by the proposed numerical approach; (b) to apply this technique to the study of synchronization stability in chaotic Hindmarsh-Rose (HR) neuronal models under uni- and bi-directional resistive coupling and different excitation bias, which also considered the root mean square synchronization error, information theoretic measures and asymmetric transfer entropy in order to offer a better insight of the synchronization phenomenon. In particular, statistical and information theoretical measures were able to capture similarity increase between the neuronal oscillators just after a critical coupling value in accordance to the largest conditional Lyapunov exponent behavior. On the other hand, transfer entropy was able to detect neuronal emitter influence even in a weak coupling condition, i.e. under the increase of conditional Lyapunov exponent and apparently desynchronization tendency. In the performed set of numerical simulations, the synchronization measures were also evaluated for a two-dimensional parameter space defined by the neuronal coupling (emitter to a receiver neuron) and the (receiver) excitation current. Such analysis is repeated for different feedback couplings as well for different (emitter) excitation currents, revealing interesting characteristics of the attained synchronization region and conditions that facilitate the emergence of the synchronous behavior. These results provide a more detailed numerical insight of the underlying behavior of a HR in the excitation and coupling space, being in accordance

  12. The FASB explores accounting for future cash flows.

    Luecke, R W; Meeting, D T

    2001-03-01

    The FASB's Statement of Financial Accounting Concepts No. 7, Using Cash Flow Information and Present Value in Accounting Measurements (Statement No. 7), presents the board's views regarding how cash-flow information and present values should be used in accounting for future cash flows when information on fair values is not available. Statement No. 7 presents new concepts regarding how an asset's present value should be calculated and when the interest method of allocation should be used. The FASB proposes a present-value method that takes into account the degree of uncertainty associated with future cash flows among different assets and liabilities. The FASB also suggests that rather than use estimated cash flows (in which a single set of cash flows and a single interest rate is used to reflect the risk associated with an asset or liability), accountants should use expected cash flows (in which all expectations about possible cash flows are used) in calculating present values.

  13. Heat transfer characteristics of horizontal steam generators under natural circulation conditions

    Hyvaerinen, J.

    1996-01-01

    This paper deals with the heat transfer characteristics of horizontal steam generators, particularly under natural circulation (decay heat removal) conditions on the primary side. Special emphasis is on the inherent features of horizontal steam generator behaviour. A mathematical model of the horizontal steam generator primary side is developed and qualitative results are obtained analytically. A computer code, called HSG, is developed to solve the model numerically, and its predictions are compared with experimental data. The code is employed to obtain for VVER 440 steam generators quantitative results concerning the dependence of primary-to-secondary heat transfer efficiency on the primary side flow rate, temperature and secondary level. It turns out that the depletion of the secondary inventory leads to an inherent limitation of the decay energy removal in VVER steam generators. The limitation arises as a consequence of the steam generator tube bundle geometry. As an example, it is shown that the grace period associated with pressurizer safety valve opening during a station black-out is 2 1/2-3 hours instead of the 5-6 hours reported in several earlier studies. (However, the change in core heat-up timing is much less-about 1 h at most.) The heat transfer limitation explains the fact that, in the Greifswald VVER 440 station black-out accident in 1975, the steam generators never boiled dry. In addition, the stability of single-phase natural circulation is discussed and insights on the modelling of horizontal steam generators with general-purpose thermal-hydraulic system codes are also presented.

    Full Text Available Injuries due to inhalation of hot gas are commonly encountered when dealing with fire and combustible material, which is harmful and threatens human life. In the literature, various studies have been conducted to investigate heat and mass transfer characteristics in the human respiratory tract (HRT. This study focuses on assessing the injury taking place in the upper human respiratory tract and identifying acute tissue damage, based on level of exposure. A three-dimensional heat transfer simulation is performed using Computational Fluid Dynamics (CFD software to study the temperature profile through the upper HRT consisting of the nasal cavity, oral cavity, trachea, and the first two generations of bronchi. The model developed is for the simultaneous oronasal breathing during the inspiration phase with a high volumetric flow rate of 90 liters/minute and the inspired air temperature of 100 degrees Celsius. The geometric model depicting the upper HRT is generated based on the data available and literature cited. The results of the simulation give the temperature distribution along the center and the surface tissue of the respiratory tract. This temperature distribution will help to assess the level of damage induced in the upper respiratory tract and appropriate treatment for the damage. A comparison of nasal breathing, oral breathing, and oronasal breathing is performed. Temperature distribution can be utilized in the design of the respirator systems where inlet temperature is regulated favoring the human body conditions.

    1996-12-31

    3-D seismic acquisition surveys in the Niger Delta of Nigeria, are carried out under extremely arduous field conditions due to difficult terrain, dense vegetation, semi-manual mode of operation, wildlife and volatile communities. The vegetation is a combination of evergreen tropical rain forest in the land areas and mangrove in the swamp areas. Some parts of the delta are prone to high seasonal flooding. Seismic lines are laid out by manual cutting of brush using machetes and shot holes drilled semi-manually with pumps. In order to effectively carry out the operations with due regard to the people and environment, a Community Affairs, Safety, Health, Environment and Security (CASHES) Polio and management System which ensures that a hazards are identified, assessed. controlled, with an effective loop feedback mechanism was introduced and implemented. CASHES critical activities are community relations, field security, explosives handling, water transport/journey management, river crossings. weather, shallow gas blow-out, waste management, seasonal flooding and floating-seaweed (water hyacinth)/timber logs. Environmental Impact Assessment (EIA) studies arc essential at the initial planning stages. About 41 Hazard Registers and 177 Activity Specification Sheets are developed in a typical survey. About 85% of the labor workforce are recruited from the host communities to promote cordial relations. Extensive training is carried out to raise the standards of the new recruits. The implementation of the management system is cascaded down using simplified documentation (procedures, work tasks, checklists etc.) adapted to local conditions. Integrated CASHES audits (Premob, Minor, Major. Follow up) arc conducted to check the efficiency of the system with documents getting reviewed regularly to keep the system alive and capable of handling changes. With these in place, high potential incidents are reduced/eliminated.

    As shown by the birth of the first cloned dog 'Snuppy', a protocol to produce viable cloned dogs has been reported. In order to evaluate optimum fusion conditions for improving dog cloning efficiency, in vivo matured oocytes were reconstructed with adult somatic cells from a female Pekingese using different fusion conditions. Fusion with needle vs chamber methods, and with low vs high pulse strength was compared by evaluating fusion rate and in vivo development of canine cloned embryos. The fusion rates in the high voltage groups were significantly higher than in the low voltage groups regardless of fusion method (83.5 vs 66.1% for the needle fusion method, 67.4 vs 37.9% for the fusion chamber method). After embryo transfer, one each pregnancy was detected after using the needle fusion method with high and low voltage and in the chamber fusion method with high voltage, whereas no pregnancy was detected using the chamber method with low voltage. However, only the pregnancy from the needle fusion method with high voltage was maintained to term and one healthy puppy was delivered. The results of the present study demonstrated that two DC pulses of 3.8 to 4.0 kV/cm for 15 μsec using the needle fusion method were the most effective method for the production of cloned dogs under the conditions of this experiment.

  5. Determination of maximum power transfer conditions of bimorph piezoelectric energy harvesters

    KAUST Repository

    Ahmad, Mahmoud Al

    2012-07-23

    In this paper, a method to find the maximum power transfer conditions in bimorph piezoelectric-based harvesters is proposed. Explicitly, we derive a closed form expression that relates the load resistance to the mechanical parameters describing the bimorph based on the electromechanical, single degree of freedom, analogy. Further, by taking into account the intrinsic capacitance of the piezoelectric harvester, a more descriptive expression of the resonant frequency in piezoelectric bimorphs was derived. In interest of impartiality, we apply the proposed philosophy on previously published experimental results and compare it with other reported hypotheses. It was found that the proposed method was able to predict the actual optimum load resistance more accurately than other methods reported in the literature. © 2012 American Institute of Physics.

MÉTODOS: Foram consultadas as bases de dados Biblioteca Cochrane, LILACS, Medline e SciELO, bem como os portais de organizações públicas. Foram selecionados os estudos que utilizaram dados primários e excluídos estudos baseados em dados secundários, artigos de revisão, estudos que não permitiram estabelecer uma associação entre PBF e segurança alimentar e nutricional, bem como os estudos que avaliaram a segurança do alimento no que se refere apenas à qualidade sanitária. RESULTADOS Foram selecionados 10 estudos, dos quais cinco concluíram que o PBF teve um impacto positivo na segurança alimentar e nutricional das famílias beneficiárias. Entretanto, três estudos constataram um aumento do consumo de alimentos de maior densidade calórica e baixo valor nutritivo. Essa mudança no hábito alimentar é um fator de risco para o desenvolvimento do sobrepeso, obesidade e das doenças crônicas não transmissíveis. CONCLUSÕES: A garantia de segurança alimentar e nutricional exige programas que contemplem tanto o combate à desnutrição quanto ao sobrepeso e à obesidade.

  17. Heat transfer in a sodium-to-sodium heat exchanger under conditions of combined force and free convection

    International Nuclear Information System (INIS)

    Jackson, J.D.; Axcell, B.P.; Johnston, S.E.

    1987-01-01

    A combined experimental and theoretical investigation of heat transfer in a vertical tube and annulus, countercurrent flow heat exchanger is reported. The working fluid was liquid sodium. Included in the range of conditions covered were those which are of interest in connection with the low flow rate operation of fast reactor intermediate heat exchanger systems. The heat transfer process ranged from that of pure forced convection to combined forced and free convection. By changing the direction of fluid flow or the direction of heat flow four different configurations were studied. In two cases the convection process was buoyancy aided and in the other two it was buoyancy opposed. Results are presented showing the influence of flow rate and temperature difference on overall heat transfer coefficient for each case. A theoretical model of turbulent flow and heat transfer incorporating influences of buoyancy was used to produce results for the range of conditions covered in the experiments. The predictions of overall heat transfer coefficient were found to be in reasonable general agreement with the measurements. It was clear from these calculations that the influence of buoyancy on heat transfer stemmed largely, under the conditions of the present experiment, from the modification of the convection process due to the distortion of the velocity field. This led to an enhancement of the heat transfer for the buoyancy-aided process and an impairment for the buoyancy-opposed process. The contribution of the turbulent diffusion of heat was relatively small. (author)

  18. Conditioned Stimuli’s Role in Relapse: Pre-Clinical Research on Pavlovian Instrumental Transfer

    Science.gov (United States)

    Lamb, R.J.; Schindler, W.; Pinkston, Jonathan W.

    2016-01-01

    Rationale and Objective Pavlovian learning is central to many theories of addiction. In these theories, stimuli paired with drug ingestion become Conditioned Stimuli (CS) and subsequently elicit drug-seeking and -taking. However in most relevant studies, Pavlovian and instrumental learning are confounded. This confound may be avoided in Pavlovian-Instrumental-Transfer (PIT) procedures. In PIT, Pavlovian and instrumental learning are established separately, and then combined. In order to better understand the role of CSs in addiction, we review the relevant studies using PIT. Findings We identified seven articles examining PIT effects of ethanol- or cocaine-paired CSs. Under at least one condition six of these articles reported CS-elicited increases in responding previously maintained by drug. However, the only study using the optimal control condition failed to find a CS-elicited increase. Two studies examining CS specificity found the CS also increased responding maintained by a different reinforcer. Two studies examined if CSs elicit increases in actual drug-taking. Both failed to find CS-elicited increases, i.e., no study shows CS-elicited increases in actual drug-taking. Further, CS-elicited increases in extinguished responding are short-lived. Conclusions These findings are not entirely consistent with Pavlovian learning playing a central role in addiction. However, design issues can explain most of these inconsistencies. Studies without these design issues are needed. Additionally, existing theories hypothesize drug-paired CSs increase drug-taking by increasing motivation, by eliciting conditioned responses that make drug-seeking more probable, or by a combination of these. Work distinguishing between these mechanisms would also be useful. PMID:26800688

    Analysis was performed for a heater infrared thermometric imaging temperature data obtained from high heat flux pool boiling and liquid film boiling experiments BETA. With the OpenFOAM solver, heat flux distribution towards the coolant was obtained by solving transient heat conduction of heater substrate given the heater surface temperature data as boundary condition. The so-obtained heat flux data was used to validate them against the state-of-art wall boiling model developed by D. R. Shaver (2015) with the assumption of micro-layer hydrodynamics. Good agreement was found between the model prediction and data for conditions away from the critical heat flux (CHF). However, the data indicate a different heat transfer pattern under CHF, which is not captured by the current model. Experimental data strengthen the notion of burnout caused by the irreversible hot spot due to failure of rewetting. The observation forms a basis for a detailed modeling of micro-layer hydrodynamics under high heat flux.

    The gap conductance between the fuel and the sheath depends strongly on the gap width and has a significant influence on the amount of initial stored energy. The modified Ross and Stoute gap conductance model in ELESTRES is based on a simplified thermal deformation model for steady-state fuel temperature calculations. A review on a series of experiments reveals that fuel pellets crack, relocate, and are eccentrically positioned within the sheath rather than solid concentric cylinders. In this paper, the two recently-proposed gap conductance models (offset gap model and relocated gap model) are described and are applied to calculate the fuel-sheath gap conductances under experimental conditions and normal operating conditions in CANDU reactors. The good agreement between the experimentally-inferred and calculated gap conductance values demonstrates that the modified Ross and Stoute model was implemented correctly in ELESTRES. The predictions of the modified Ross and Stoute model provide conservative values for gap heat transfer and fuel surface temperature compared to the offset gap and relocated gap models for a limiting power envelope. 13 figs., 3 tabs., 16 refs.

    Full Text Available This study aims to examine the effect of corporate tax avoidance to the corporate cash holdings. Recent tax avoidance research found that tax avoidance is able to facilitate managerial rent extraction in the form of transfer of resources owned by the company. This study attempts to test how the relationship of tax avoidance with the amount of cash held by the company. The sample consists of 46 non-financial, non-property, non-real estate and non-construction companies from 2009-2016, with a total 368 observations. The study uses two different cash holdings measures to test the robustness of the research results. This study cannot find evidence that tax avoidance have a significant relationship to the level of cash holdings in public companies in Indonesia. Both measurements of cash holdings gave the same conclusions to the results of the study. This study provides an insight that agency theory in the context of tax avoidance and corporate cash holdings in developing countries such as Indonesia needs to be explored further as the agency conflict in Indonesia as a developing country is more principal-principal conflicts.

    The new AP600 reactor designed by Westinghouse uses a passive safety system relying on heat removal by condensation to keep the containment within the design limits of pressure and temperature. Even though some research has been done so far in this regard, there are some uncertainties concerning the behavior of the system under postulated accident conditions. In this paper, steam condensation onto the internal surfaces of the AP600 containment walls has been investigated in two scaled vessels with similar aspect ratios to the actual AP600. The heat transfer degradation in the presence of noncondensable gas has been analyzed for different noncondensable mixtures of air and helium (hydrogen simulant). Molar fractions of noncondensables/steam ranged from (0.4-4.0) and helium concentrations in the noncondensable mixture were 0-50% by volume. In addition, the effects of the bulk temperatures, the mass fraction of noncondensable/steam, the cold wall surface temperature, the pressure, noncondensable composition, and the inclination of the condensing surface were studied. It was found that the heat transfer coefficients ranged from 50 to 800 J s -1 K -1 m -2 with the highest for high wall temperatures at high pressure and low noncondensable molar fractions. The effect of a light gas (helium) in the noncondensable mixture were found to be negligible for concentrations less than approximately 35 molar percent but could result in stratification at higher concentrations. The complete study gives a large and relatively complete data base on condensation within a scaled AP600 containment structure, providing an invaluable set of data against which to validate models. In addition, specific areas requiring further investigation are summarized. (orig.)

    The majority of the material in support of the thermal - hydraulic safety of WWER core was obtained on single - assembly models containing a relatively small number of elements - heater rods. Upgrading the requirements to the reactor safety leads to the necessity for studying phenomena in channels representing the cross - sectional core dimensions and non - uniform radial power generation. Under such conditions, the contribution of natural convection can be significant in some core zones, including the occurrence of reverse flows and interchannel instability. These phenomena can have an important influence on heat transfer processes. Such influence is especially drastical under accident conditions associated with ceasing the forced circulation over the circuit. A number of urgent reactor safety problems at low operating parameters is related with the computer code verification and certification. One of the important trends in the reactor safety research is concerned with the rod bundle reflooding and verificational calculations of this phenomenon. To assess the water cooled reactor safety, the best fit computer codes are employed, which make it possible to simulate accident and transient operating conditions in a reactor installation. One of the most widely known computer codes is the RELAP5/MOD3 Code. The paper presents the comparison of the results calculated using this computer code with the test data on 4 - rod bundle quenching, which were obtained at the SSCRF-IPPE. Recently, the investigations on the steam - zirconium reaction kinetics have been performed at the SSCFR-IPPE and are being presently performed for the purpose of developing new and verifying available computer codes.

Reading through this paper must provide us with the ability to choose and correctly apply the methods presented in order to estimate the enterprise value. Understanding the method cash - flow update – is conditioned by the differentiation between collection and income, fees and expenses. The profit is the result of comparing revenues and expenses. Not all revenue generate collection at the same time; not all expenses generate payments. Their registration into accounting is delayed. Cash-flow is the evolution of the availability of funds in itself of the company, the evolution of the net treasury. In summary, we note that approach based on income estimates an enterprise value by converting future streams of income in the present value of an enterprise which can generate those cash flows.

  7. Prudency reviews, cash management issues emerge

    Utility management is paying increasing attention to the broadening of regulatory commission prudency reviews to cover operating generating plants as well as those under construction. Utilities can expect a prudency review after a major outage, and should investigate the possibility for legal action against a third party or be prepared to defend itself. The Shoreham nuclear plant serves as a warning to utilities of the need for on-going documentation of cost-benefit analyses conducted during the construction period. Utility managers should demand a prudency standard from their regulators, and minority owners in large projects should make independent prudency findings. There is also a growing need for utilities to develop intelligent strategies for handling excess cash. Methods for handling cash flow include the financial investment, grid refurbishment, dividend payout, decapitalization, and diversification

    1985-01-01

    An experimental set-up is described and the results of temperature pulsation investigation are presented for coil steam generating channel surfaces of the NPP helium and sodium cooled HTGR. The investigations are carried out at the heat flux density of 350-900 kW/m 3 , the mass rate of 350-2000 kg/(m 2 Xs), the pressUre of 15 MPa. Temperature pulsations occur due to instability of heat transfer in the near-wall region. The results show that the critical region of burnout has a local character. Pulsation dependences on operating conditions are given. The required resource for the steam generating channel may be provided by chosing the ratio of heat flux to the mass rate, the ratio being equal to 0.5 kJ/kg for the channel with the internal diameter of 19 mm, made of the 12Kh2M steel, the wall thickness of 3 mm. In this case the maximum span of temperature pulsations doesn't exceed 25-30 K

  11. Acceleration of radiative transfer model calculations for the retrieval of trace gases under cloudy conditions

    In the independent pixel approximation (IPA), radiative transfer computations involving cloudy scenes require two separate calls to the radiative transfer model (RTM), one call for a clear sky scenario, the other for an atmosphere containing clouds. In this paper, clouds are considered as an optically homogeneous layer. We present two novel methods for RTM performance enhancement with particular application to trace gas retrievals under cloudy conditions. Both methods are based on reusing results from clear-sky RTM calculations to speed up corresponding calculations for the cloud-filled scenario. The first approach is numerically exact, and has been applied to the discrete-ordinate with matrix exponential (DOME) RTM. Results from the original clear sky computation can be saved in the memory and reused for the non-cloudy layers in the second computation. In addition, for the whole-atmosphere boundary-value approach to the determination of the intensity field, we can exploit a ’telescoping technique’ to reduce the dimensionality (and hence the computational effort for the solution) of the boundary value problem in the absence of Rayleigh scattering contributions for higher azimuthal components of the radiation field. The second approach is (for the cloudy scenario) to generate a spectral correction applied to the radiation field from a fast two-stream RTM. This correction is based on the use of principal-component analysis (PCA) applied to a given window of spectral optical property data, in order to exploit redundancy in the data and confine the number of full-stream multiple scatter computations to the first few EOFs (Empirical Orthogonal Functions) arising from the PCA. This method has been applied to the LIDORT RTM; although the method involves some approximation, it provides accuracy better than 0.2%, and a speed-up factor of approximately 2 compared with two calls of RTM. -- Highlights: • Reusing results from clear-sky computations for a model with a

Limits were placed on the transfer and back-dilution volumes because of concerns about potential gas release, crust sinking, and degradation of mixer pump performance. Additional transfers and back-dilutions are being planned that will bring the total to 500 kgal, which should dissolve a large fraction of the solids in the tank and dilute it well beyond the point where significant gas retention can occur. This report provides the technical bases for removing the limits on transfer and back-dilution volume by evaluating the potential consequences of several postulated hazardous conditions in view of the results of the first campaign and results of additional analyses of waste behavior

  18. Boiling Heat Transfer Mechanisms in Earth and Low Gravity: Boundary Condition and Heater Aspect Ratio Effects

    Science.gov (United States)

    Kim, Jungho

    2004-01-01

    Boiling is a complex phenomenon where hydrodynamics, heat transfer, mass transfer, and interfacial phenomena are tightly interwoven. An understanding of boiling and critical heat flux in microgravity environments is of importance to space based hardware and processes such as heat exchange, cryogenic fuel storage and transportation, electronic cooling, and material processing due to the large amounts of heat that can be removed with relatively little increase in temperature. Although research in this area has been performed in the past four decades, the mechanisms by which heat is removed from surfaces in microgravity are still unclear. Recently, time and space resolved heat transfer data were obtained in both earth and low gravity environments using an array of microheaters varying in size between 100 microns to 700 microns. These heaters were operated in both constant temperature as well as constant heat flux mode. Heat transfer under nucleating bubbles in earth gravity were directly measured using a microheater array with 100 m resolution operated in constant temperature mode with low and high subcooled bulk liquid along with images from below and from the side. The individual bubble departure diameter and energy transfer were larger with low subcooling but the departure frequency increased at high subcooling, resulting in higher overall heat transfer. The bubble growth for both subcoolings was primarily due to energy transfer from the superheated liquid layer relatively little was due to wall heat transfer during the bubble growth process. Oscillating bubbles and sliding bubbles were also observed in highly subcooled boiling. Transient conduction and/or microconvection was the dominant heat transfer mechanism in the above cases. A transient conduction model was developed and compared with the experimental data with good agreement. Data was also obtained with the heater array operated in a constant heat flux mode and measuring the temperature distribution across

    Highlights: ► Measured subcooled boiling pressure drop and local heat transfer coefficient in horizontal tubes. ► Infra-red thermal imaging is used for wall temperature measurement. ► Developed correlations for pressure drop and local heat transfer coefficient. -- Abstract: Horizontal flow is commonly encountered in boiler tubes, refrigerating equipments and nuclear reactor fuel channels of pressurized heavy water reactors (PHWR). Study of horizontal flow under low pressure and low flow (LPLF) conditions is important in understanding the nuclear core behavior during situations like LOCA (loss of coolant accidents). In the present work, local heat transfer coefficient and pressure drop are measured in a horizontal tube under LPLF conditions of subcooled boiling. Geometrical parameters covered in this study are diameter (5.5 mm, 7.5 mm and 9.5 mm) and length (550 mm, 750 mm and 1000 mm). The operating parameters varied are mass flux (450–935 kg/m 2 s) and inlet subcooling (29 °C, 50 °C and 70 °C). Infra-red thermography is used for the measurement of local wall temperature to estimate the heat transfer coefficient in single phase and two phase flows with water as the working medium at atmospheric pressure. Correlation for single phase diabatic pressure drop ratio (diabatic to adiabatic) as a function of viscosity ratio (wall temperature to fluid temperature) is presented. Correlation for pressure drop under subcooled boiling conditions as a function of Boiling number (Bo) and Jakob number (Ja) is obtained. Correlation for single phase heat transfer coefficient in the thermal developing region is presented as a function of Reynolds number (Re), Prandtl number (Pr) and z/d (ratio of axial length of the test section to diameter). Correlation for two phase heat transfer coefficient under subcooled boiling condition is developed as a function of boiling number (Bo), Jakob number (Ja) and Prandtl number (Pr)

    Full Text Available Since state institutions began using account screening, in the bank sector, not only in cases of suspicion, but as a standard procedure for monitoring account and invest-ment data, much of the illegal transfer of funds has shifted towards cash payments. In order to hinder, or even do away with such illegal monetary transactions, the EU is considering two possible courses of action; one moderate and one more radical. The moderate solution would see the introduction of legislation restricting the amount of cash used in payments. Several countries already have such legislation. It is possible that this limit could be adjusted by governments ad hoc, and could even be set at zero. This would be the radical course of action; doing away completely with cash payments. The consequence would be that the transfer of money would only be possible by bank transfer from account to account. Representatives of the banking sector are in favour of the campaign to eliminate the use of cash transactions, as this would lead to advantages within the banking indus-try. However, there would be many disadvantages for the general public. In the world of commerce, contractual liberty is a fundamental principle. All contracting parties have the right, within the law, to negotiate the terms of a contract to be signed, laying down goods or payment (cash included to be made, as a part of the contract. Thus, legislation restricting the use of cash would be a breach of the free-dom of rights as laid down in the constitution of any EU country. The question as to whether or not to do away with the use of 500, - Euro bank notes is of little interest to legal and private monetary transactions, as these are seldom used in such cases. Since these notes are a simple way of transporting large sums of money unnoticed, their use is mainly limited to the world of illegal transactions where large sums of money need to be moved, as in the case of money laundering

    2007-06-01

    Full Text Available Using firm-level data from thirty-five countries around the world, this paper empirically examines whether investment-cash flow sensitivity reflects financial constraints. Recent US studies have raised questions on the prediction that investment-cash flow sensitivity is a measure of financial constraints. Looking at thirty-five countries with varying degrees of financial development, this study tests whether investment-cash flow sensitivity is in fact related to financial constraints. In most countries, the evidence supporting the argument that firms likely facing financially constraints display high investment-cash flow sensitivity is weak. Moreover, the evidence that firms in the absence of developed financial markets display high investment-cash flow sensitivity is also weak. Overall, the results from this international investigation do not support the prediction that investment-cash flow sensitivity reflects financial constraints.

    Full Text Available This paper investigates how corporate cash holdings were adjusted over time for Brazilian companies during the crisis of 2008-2009. We adopt a dynamic model of corporate cash holdings to evaluate the main determinants for the speed of adjustment of cash holdings at the optimum level. We find evidence that: a the adjustment costs of Brazilian companies are high implying a delay in reaching the optimum level of cash; b the low speed adjustment to the optimum level is due to the limited availability of credit and the high cost of bank debt; c during crisis, the changes in working capital are positively related to the level of cash holdings providing evidence that companies prefer finance to growth with liquidity; d companies have looked for long-term financing to secure liquidity rather than investing on fixed assets, implying a negative relationship between investment and cash holding.

    Electronization of banking services is a  strong reason for relative growth of cashless payments. The importance of cash, i.e., banknotes and coins, for realizing transactions should decrease. An analysis for the Czech Republic in the period 2003–2015 confirms this. Demand of nonbank entities for cash is associated mainly with liquidity, banks’ credibility and technological sophistication. Illegal transactions also form part of the demand. Zero return on cash counteracts demand, but it has li...

    2014-01-01

    This work presents a numerical and experimental investigation on the heat transfer and turbulent flow of cooling steam in a rectangular duct with 90 .deg. ribs and studies the effect of cooling conditions on the heat transfer augmentation of steam. In the calculation, the variation range of Reynolds is from 10,000 to 190,000, the inlet temperature varies from 300 .deg. C to 500 .deg. C and the outlet pressure is from 0.5MPa to 6MPa. The aforementioned wide ranges of flow parameters cover the actual operating condition of coolant used in the gas turbine blades. The computations are carried with four turbulence models (the standard k-ε, the renormalized group (RNG) k-ε, the Launder-Reece-Rodi (LRR) and the Speziale-Sarkar-Gatski (SSG) turbulence models). The comparison of numerical and experimental results reveals that the SSG turbulence model is suitable for steam flow in the ribbed duct. Therefore, adopting the conjugate calculation technique, further study on the steam heat transfer and flow characteristics is performed with SSG turbulence model. The results show that the variation of cooling condition strongly impacts the forced convection heat transfer of steam in the ribbed duct. The cooling supply condition of a relative low temperature and medium pressure could bring a considerable advantage on steam thermal enhancement. In addition, comparing the heat transfer level between steam flow and air flow, the performance advantage of using steam is also influenced by the cooling supply condition. Changing Reynolds number has little effect on the performance superiority of steam cooling. Increasing pressure would strengthen the advantage, but increasing temperature gives an opposite result.

    Full Text Available The majority of the population in Sub-Saharan Africa is employed in agriculture. Nevertheless, the productivity of the sector is relatively low in comparison with other regions of the world. Based on convergence theory, technology transfer can enhance growth. However, the effective transfer of technology requires a certain absorption capacity from the recipient. Based on the qualitative research on cassava production in Congo Brazzaville, we identified key factors that influence the transfer process. These factors have been divided into four key areas: market, institutions, technology, and social capability. Cassava production value chain in Ignie region served as a case study for the evaluation of technology transfer absorptive capacity in Congo agriculture. We learned that the lack of agro-technical education, shortages in infrastructure, unavailability of business services, and market structure are among the main barriers of the intensification of technology use in agriculture.

    We explored the theoretical underpinnings of a commonly used training strategy by examining issues of training and transfer of skill in the context of a complex video game (Space Fortress, Donchin, 1989). Participants trained using one of two training regimens: Full Emphasis Training (FET) or Variable Priority Training (VPT). Transfer of training was assessed with a large battery of cognitive and psychomotor tasks ranging from basic laboratory paradigms measuring reasoning, memory, and attention to complex real-world simulations. Consistent with previous studies, VPT accelerated learning and maximized task mastery. However, the hypothesis that VPT would result in broader transfer of training received limited support. Rather, transfer was most evident in tasks that were most similar to the Space Fortress game itself. Results are discussed in terms of potential limitations of the VPT approach.

    Abd Elazem, Nader Y.; Ebaid, Abdelhalim

    2017-12-01

    In this paper, the effect of partial slip boundary condition on the heat and mass transfer of the Cu-water and Ag-water nanofluids over a stretching sheet in the presence of magnetic field and radiation. Such partial slip boundary condition has attracted much attention due to its wide applications in industry and chemical engineering. The flow is basically governing by a system of partial differential equations which are reduced to a system of ordinary differential equations. This system has been exactly solved, where exact analytical expression has been obtained for the fluid velocity in terms of exponential function, while the temperature distribution, and the nanoparticles concentration are expressed in terms of the generalized incomplete gamma function. In addition, explicit formulae are also derived from the rates of heat transfer and mass transfer. The effects of the permanent parameters on the skin friction, heat transfer coefficient, rate of mass transfer, velocity, the temperature profile, and concentration profile have been discussed through tables and graphs.

    In practice management, general practice falls into the category of small business with all its attendant generic problems. Disciplined planning and good financial management are not often seen in small business. These are required if general practitioners are to continue (or return to) the provision of high quality medical services. An effective budget process, especially cash-flow budgeting, is the key to successful planning and financial management. Budgeting will bring Control, Co-ordination, and Credibility to your practice. It will enable you to set goals and to achieve them.

  17. How does Cash and Counseling affect costs?

    2007-02-01

    To test the effect of a consumer-directed model (Cash and Counseling) of Medicaid personal care services (PCS) or home- and community-based waiver services (HCBS) on the cost of Medicaid services. Medicaid claims data were collected for all enrollees in the Cash and Counseling demonstration. Demonstration enrollees included those eligible for PCS (in Arkansas), those assessed to receive such services (in New Jersey), and recipients of Medicaid HCBS (in Florida). Enrollment occurred from December 1998 through April 2001. The follow-up period covered up to 24 months after enrollment. Demonstration volunteers were randomly assigned to have the option to participate in Cash and Counseling (the treatment group), or to receive Medicaid services as usual from an agency (the control group). Ordinary least squares regressions were used to estimate the effect of the program on costs for Medicaid PCS/waiver services and other Medicaid services, while controlling for consumers' preenrollment characteristics and preenrollment Medicaid spending. Models were estimated separately for nonelderly and elderly adults in each state and for children in Florida. Each state supplied claims data for demonstration enrollees. Largely because the program increased consumers' ability to get the authorized amount of paid care, expenditures for personal care/waiver services were higher for the treatment group than for the control group in each state and age group, except among the elderly in Florida. Higher costs for personal care/waiver services were partially offset by savings in other Medicaid services, particularly those related to long-term care. During year 1, total Medicaid costs were generally higher for the treatment group than for the control group, with treatment-control cost differences ranging from 1 percent (and statistically insignificant) for the elderly in Florida to 17 percent for the elderly in Arkansas. In year 2, these cost differences were generally greater than in year 1

    This paper explores how present value varies over time when the underlying cash flow has a deterministic period. I assume that cash flows are known with certainty and follow a cycle with a long or short period. When the cash flow has a short period, the present value is relatively stable over time because the present value calculation smooths out several cycles. However, when the cash flow has a long period the present value itself develops a long and large cycle. These results are driven...

    2013-01-01

    When their CERN contracts expire and they leave the Organization, Fellows recoup the amounts paid into the Pension Fund by and for them every month. If they invest this money well, right from the outset, it can grow into a nice little nest-egg by the time they reach retirement age.   As employed members of the CERN personnel, Fellows are members of the Organization’s Pension Fund. Accordingly, a specific amount is withheld from their salary every month (see first box) and, as the months go by, this gradually accumulates into their transfer value (i.e. their capital). When their contracts expire, Fellows may opt to transfer that money directly into another pension fund (subject to the national laws of the destination country and, unfortunately, not possible everywhere), or take it in cash. This is because only employed members of the personnel who have at least five years of service with the Organization are entitled to remain beneficiaries of the CERN Pension Fund for life*.

    2016-03-04

    Phenolic compounds are responsible of the nutritional and sensory quality of extra-virgin olive oil (EVOO). The composition of phenolic compounds in EVOO is related to the initial content of phenolic compounds in the olive-fruit tissues and the activity of enzymes acting on these compounds during the industrial process to produce the oil. In this work, the phenolic composition was studied in six major cultivars grown in the same orchard under the same agronomical and environmental conditions in an effort to test the effects of cultivars on phenolic composition in fruits and oils as well as on transfer between matrices. The phenolic fractions were identified and quantified using high-performance liquid chromatography-diode array detector-time-of-flight-mass spectrometry. A total of 33 phenolic compounds were determined in the fruit samples and a total of 20 compounds in their corresponding oils. Qualitative and quantitative differences in phenolic composition were found among cultivars in both matrices, as well as regarding the transfer rate of phenolic compounds from fruits to oil. The results also varied according to the different phenolic groups evaluated, with secoiridoids registering the highest transfer rates from fruits to oils. Moreover, wide-ranging differences have been noticed between cultivars for the transfer rates of secoiridoids (4.36%-65.63% of total transfer rate) and for flavonoids (0.18%-0.67% of total transfer rate). 'Picual' was the cultivar that transferred secoiridoids to oil at the highest rate, whereas 'Changlot Real' was the cultivar that transferred flavonoids at the highest rates instead. Principal-component analysis confirmed a strong genetic effect on the basis of the phenolic profile both in the olive fruits and in the oils.

  8. Serpentine tube heat transfer characteristic under accident condition in gas cooled reactors

    2004-01-01

    In nuclear reactors of the Magnox or advanced gas Cooled type, serpentine tubing is used in some designs to generate steam in a once through arrangement. The calculation of accident conditions using two phase flow codes requires knowledge of the heat transfer behavior of the boiler steam side. A series of experiments to study the blowdown characteristics of a typical serpentine boiler section was devised in order to validate the MARTHA section of the MACE code used by nuclear Electric. The tests were carried out on the Thermal Hydraulics Experimental Research Assembly (THERA) loop at Manchester University. The Thermal Hydraulic Experimental Research Assembly was designed to operate with pressures up to 180 bar and temperatures of 450degC. The geometry and dimensions of this test section were similar to part of a gas cooled reactor boiler of the Hinkley Point design. Blowdown from a pressure of 60 bar with subcoolings of 5degC, 50degC, 100degC formed the main part of the programme. A set of tests was conducted using discharge orifices of different sizes to produce depressurization times from 30 s to 10 mins, and in a few cases, the duration of blowdown approached 1 hour. These times were defined using the criterion of blowdown end as a final pressure of 10% of the initial pressure. Pressures, wall and fluid temperatures were all measured at average time intervals of 1.1s during the excursion and an inventory of the remaining water content in the serpentine was taken when the blowdown ended. Some tests were also conducted at an initial pressure of 30 bar. The results obtained show interesting stratification effects for the relatively fast discharge, with substantial wall circumferential temperature variations. For these tests, a relatively small water inventory remained after blowdown. The discharge characteristics of the serpentine in terms of orifice size have been mapped, and tests at 30 bar show the equivalence in terms of orifice size have been mapped

    Pavlovian conditioning in animals is often evaluated by means of transfer of control experiments. With human subjects, however, only very few studies have been conducted and the outcomes were often not in accordance with theoretical explanations based on studies with animals. A theoretical framework is presented that tries to integrate the results of the human conditioning paradigm and the animal conditioning paradigm as well, with reference to the well-known Yerkes-Dodson law. The experimental study with human subjects (N = 24) confirmed the predictions out of this framework, when a procedure similar to animal research is applied.

    The radionuclides 14 C and 3 H may both be released from nuclear facilities. These radionuclides are unusual, in that they are isotopes of macro-elements which form the basis of animal tissues, feed and, in the case of 3 H, water. There are few published values describing the transfer of 3 H and 14 C from feed to animal derived food products under steady state conditions. Approaches are described which enable the prediction of 14 C and 3 H transfer parameter values from readily available information on the stable H or C concentration of animal feeds, tissues and milk, water turnover rates, and feed intakes and digestibilities. We recommend that the concentration ratio between feed and animal product activity concentrations be used as it is less variable than the transfer coefficient (ratio between radionuclide activity concentration in animal milk or tissue to the daily intake of a radionuclide)

    The process of heat transfer in an evaporation-condensation system (ECS) at circulation of dielectric liquid in a closed thermoelectrohydrodynamic (TEHD) loop consisting of an evaporator, a condenser and electrohydrodynamic (EHD) pump for pumping of heat carrier, is considered. Previously, the authors studied the dependence of heat transfer on the angle of rotation of TEHD loop in a vertical plane. The report contains the results of studies of heat transfer at electrohydrodynamic pumping of the heat carrier (8% solution of acetone in Freon 113) in the condenser area by means of EHD pump of “cone-cone” type. All elements of the ECS are arranged in a horizontal plane and the heat transfer from the heater to the condenser without EHD pumping is impossible. A pulsating heat carrier flow mode, depending on the heat input and the voltage applied to the pump, takes place at EHD pumping. As the input power is decreasing the frequency of the coolant pulsations as well as the departure diameter and number of vapour bubbles are also decreasing. At some critical heat input the pulsations disappear and the transition from turbulent mode to the laminar one takes place causing the decrease of the heat transfer coefficient. The increase of the pumping flow rate by raising the voltage applied to the EHD pump, results in a partial suppression of boiling. The maximum intensification of heat transfer is reached at pulsation frequency of 1.25 Hz. The maximum heat flow from the heater was 4.2·104 W/m2. Graphical representation and the physical interpretation of the results, which reflect the essence of the process, are given.

Moreover the deformation motion of fluid micelle is simply analyzed. Nonlinear velocity equation are formulated with multi-term time fractional derivatives in the boundary layer governing equations, and convective heat transfer boundary condition and viscous dissipation are both taken into consideration. A newly finite difference scheme with L1-algorithm of governing equations are constructed, whose convergence is confirmed by the comparison with analytical solution. Numerical solutions for velocity and temperature show the effects of pertinent parameters on flow and heat transfer of fractional Maxwell fluid. It reveals that the fractional derivative weakens the effects of motion and heat conduction. The larger the Nusselt number is, the greater the heat transfer capacity of fluid becomes, and the temperature gradient at the wall becomes more significantly. The lower Reynolds number enhances the viscosity of the fluid because it is the ratio of the viscous force and the inertia force, which resists the flow and heat transfer.

  15. Reliably measuring the condition of mineral-based transfer fluids using a permittivity sensor – practical application to thermal fluid heat transfer

    Directory of Open Access Journals (Sweden)

    Christopher Ian Wright

    2015-09-01

    Full Text Available This article describes a series of experiments to assess the performance and suitability of a permittivity sensor in the area of heat transfer. The permittivity sensor measures condition index and temperature of a fluid. A series of 5 experiments was conducted. They assessed the reproducibility of the sensor using both clean and dirty fluid samples, and showed the sensor had good reproducibility based on calculations of coefficients of variation. The sensor also detected water contamination, assessed from construction of a stimulus-response curve to step-wise increases in water and from real-life samples where water content was reported to be out of specification. Further experiments tested the association between condition index and both water content and fluid cleanliness in a real-life setting. Results demonstrated the sensor that condition index reflected changes in fluid water and cleanliness and was therefore a measure of fluid condition. The implication of these findings is that the sensor can be used to make rapid and reliable assessments of fluid condition using only small samples (i.e., <50 ml. The sensor may be of benefit to customers that need to make a lot of regular samples over a large processing site, such as concentrated solar power plants.

    Directory of Open Access Journals (Sweden)

    Zbyněk Revenda

    2017-03-01

    Full Text Available Electronization of banking services is a  strong reason for relative growth of cashless payments. The importance of cash, i.e., banknotes and coins, for realizing transactions should decrease. An analysis for the Czech Republic in the period 2003–2015 confirms this. Demand of nonbank entities for cash is associated mainly with liquidity, banks’ credibility and technological sophistication. Illegal transactions also form part of the demand. Zero return on cash counteracts demand, but it has little meaning with the decline in interest rates on bank deposits. The total stock of cash in the analyzed period rises, but its relative importance declines. Demand deposits are also liquid assets of households and enterprises. Cash compared with demand deposits clearly confirms the declining importance. Its share was the highest in 2004, at 30 %. It fell to less than 18 % in 2015. We found a similar tendency in the comparison of cash with other variables. Barring unforeseen circumstances such as complete collapse of computer networks or severe banking crisis, the author assumes that the relative importance of cash must decline in the long term. Some theoretical aspects of cash and cashless money are also discussed.

    2015-05-01

    Full Text Available This research expands on previous studies of cash holdings and their determinants by studying the relationship between the degree of internationalization and the level of corporate cash holdings. We used a sample of nonfinancial, publicly traded companies from Brazil and Mexico for the period from 2006 to 2010. Our results suggest that the degree of internationalization is a determinant of cash, and that cash holding increases quadratically as the degree of company internationalization grows. Such behavior was different from the North American company studies in Chiang and Wang (2011. Similar to previous studies, both Trade-off and Pecking Order predictions are relevant control variables in our model. Finally, companies held less cash on their balance sheets during the precrisis period.

    Highlights: ► Mass transfer downstream of orifices was numerically and experimentally investigated. ► The surface wear pattern is measured and used to validate the present numerical results. ► The maximum mass transfer coefficient found to occur at approximately 2–3 pipe diameters downstream of the orifice. ► The FAC wear rates were correlated with the turbulence kinetic energy and wall mass transfer in terms of Sherwood number. ► The current study offered very useful information for FAC engineers for better preparation of nuclear plant inspection scope. - Abstract: Local flow parameters play an important role in characterizing flow accelerated corrosion (FAC) downstream of sudden area change in power plant piping systems. Accurate prediction of the highest FAC wear rate locations enables the mitigation of sudden and catastrophic failures, and the improvement of the plant capacity factor. The objective of the present study is to evaluate the effect of the local flow and mass transfer parameters on flow accelerated corrosion downstream of an orifice. In the present study, orifice to pipe diameter ratios of 0.25, 0.5 and 0.74 were investigated numerically by solving the continuity and momentum equations at Reynolds number of Re = 20,000. Laboratory experiments, using test sections made of hydrocal (CaSO 4 ·½H 2 O) were carried out in order to determine the surface wear pattern and validate the present numerical results. The numerical results were compared to the plants data as well as to the present experiments. The maximum mass transfer coefficient found to occur at approximately 2–3 pipe diameters downstream of the orifice. This location was also found to correspond to the location of elevated turbulent kinetic energy generated within the flow separation vortices downstream of the orifice. The FAC wear rates were correlated with the turbulence kinetic energy and wall mass transfer in terms of Sherwood number. The current study found to offer very

  20. FREE CASH FLOW AS PART OF VOLUNTARY REPORTING. LITERATURE REVIEW

    Directory of Open Access Journals (Sweden)

    Negrea Laura Georgeta

    2011-12-01

    Full Text Available The present study has as main objective to reflect the state of literature regarding free cash flow, and to withdraw the main pro's and con's in order to create an objective image upon this indicator. The main idea generating this research was the growing interest on cash flow reporting. As many say, 'Cash Flow is King', while in Anglo Saxon countries the interest of investors and analysts in concentrated on operating cash flow, as the most important indicator of the probability of bankruptcy. In this context, voluntary additional reporting, like free cash flow may come either as an aid in providing the fair view or as an opportunistically reported figure. Throughout the paper, the intention was to provide answers to three main research questions: What are the definition and calculation method of free cash flow? Why is there an interest in free cash flow reporting? What is the impact of free cash flow on the agency theory? In order to provide relevant conclusions, four international data basis were used, and related articles and studies were extracted. The results proved that there is no generally accepted definition and computing method, while the format depends on the end-user of the report (shareholders, investors, analysts, bankers, a.s.o.. As stated below, this aspect generates confusion and lack of comparability, giving room to creative accounting techniques. Moreover, the interest on free cash flow reporting is connected mainly to liquidity assessment, company valuation and investors choice. Still, in the context of agency theory, results show that in presence of high free cash flow, managers tend to make investment choices that satisfy their personal interest and that generate low efficiency and profitability for the company. The contribution to current state of research is providing a literature review study, focused on a comparative approach, as well as on underlying an objective image upon a debatable financial indicator and

    Uncertain time of retirement and uncertain structure of retirement benefits are risk factors for life insurance companies. Nevertheless, classical life insurance models assume these are deterministic. In this paper, we include the risk from stochastic time of retirement and stochastic benefit...... structure in a classical finite-state Markov model for a life insurance contract. We include discontinuities in the distribution of the retirement time. First, we derive formulas for appropriate scaling of the benefits according to the time of retirement and discuss the link between the scaling...... and the guarantees provided. Stochastic retirement creates a need to rethink the construction of disability products for high ages and ways to handle this are discussed. We show how to calculate market reserves and how to use modified transition probabilities to calculate expected cash flows without significantly...

    Rio, Donald C

    2015-03-02

    In this protocol, an RNA sample, fractionated by gel electrophoresis, is transferred from the gel onto a membrane by capillary transfer. Short-wave UV light is used to fix the transferred RNA to the membrane. The membrane is then pretreated to block nonspecific probe-binding sites, and hybridization of the immobilized RNA to a (32)P-labeled DNA or RNA probe specific for the mRNA of interest is performed. Finally, the membrane is washed and subjected to autoradiography or phosphorimaging. Because exposure to UV cross-links the RNA to the membrane, the membrane can be stripped and hybridized with other probes. The procedure is suitable for detecting poly(A)(+)-selected mRNA or mRNA in total cellular RNA if the target transcript is relatively abundant. Using DNA or RNA probes labeled to 1 × 10(8)-10 × 10(8) cpm/µg, it should be possible to detect ∼5 pg of a specific RNA. © 2015 Cold Spring Harbor Laboratory Press.

    2006-01-01

    An experimental program has been completed to study the behaviour of sheath wall temperatures in the Bruce Power Station Low Void Reactivity Fuel (shortened hereafter to Bruce LVRF) bundles under post-dryout (PDO) heat-transfer conditions. The experiment was conducted with an electrically heated simulator of a string of nine Bruce LVRF bundles, installed in the MR-3 Freon heat transfer loop at the Chalk River Laboratories (CRL), Atomic Energy of Canada Limited (AECL). The loop used Freon R-134a as a coolant to simulate typical flow conditions in CANDU R nuclear power stations. The simulator had an axially uniform heat flux profile. Two radial heat flux profiles were tested: a fresh Bruce LVRF profile and a fresh natural uranium (NU) profile. For a given set of flow conditions, the channel power was set above the critical power to achieve dryout, while heater-element wall temperatures were recorded at various overpower levels using sliding thermocouples. The maximum experimental overpower achieved was 64%. For the conditions tested, the results showed that initial dryout occurred at an inner-ring element at low flows and an outer-ring element facing internal subchannels at high flows. Dry-patches (regions of dryout) spread with increasing channel power; maximum wall temperatures were observed at the downstream end of the simulator, and immediately upstream of the mid-bundle spacer plane. In general, maximum wall temperatures were observed at the outer-ring elements facing the internal subchannels. The maximum water-equivalent temperature obtained in the test, at an overpower level of 64%, was significantly below the acceptable maximum temperature, indicating that the integrity of the Bruce LVRF will be maintained at PDO conditions. Therefore, the Bruce LVRF exhibits good PDO heat transfer performance. (authors)

    To predict the stability of pharmaceutical preparations under uncontrolled temperature conditions accurately, a method to compute the average reaction rate constant taking into account the heat transfer from the atmosphere to the product was developed. The average reaction rate constants computed with taken into consideration heat transfer (κ(re) ) were then compared with those computed without taking heat transfer into consideration (κ(in) ). The apparent thermal diffusivity (κ(a) ) exerted some influence on the average reaction rate constant ratio (R, R = κ(re) /κ(in) ). In the regions where the κ(a) was large (above 1 h(-1) ) or very small, the value of R was close to 1. On the contrary, in the middle region (0.001-1 h(-1) ), the value of R was less than 1.The κ(a) of the central part of a large-size container and that of the central part of a paper case of 10 bottles of liquid medicine (100 mL) fell within this middle region. On the basis of the above-mentioned considerations, heat transfer may need to be taken into consideration to enable a more accurate prediction of the stability of actual pharmaceutical preparations under nonisothermal atmospheres.

    A multidimensional quantum mechanical protocol is used to describe the photoinduced electron transfer and electronic coherence in plant cryptochromes without any semiempirical, e.g., experimentally obtained, parameters. Starting from a two-level spin-boson Hamiltonian we look at the effect that the initial photoinduced nuclear bath distribution has on an intermediate step of this biological electron transfer cascade for two idealized cases. The first assumes a slow equilibration of the nuclear bath with respect to the previous electron transfer step that leads to an ultrafast decay with little temperature dependence; while the second assumes a prior fast bath equilibration on the donor potential energy surface leading to a much slower decay, which contrarily displays a high temperature dependence and a better agreement with previous theoretical and experimental results. Beyond Marcus and semiclassical pictures these results unravel the strong impact that the presence or not of equilibrium initial conditions has on the electronic population and coherence dynamics at the quantum dynamics level in this and conceivably in other biological electron transfer cascades.

    A field study was conducted at the Russell E. Larson Agricultural Research Center to determine the effect of transgenic glyphosate-resistant soybean in combination with herbicide (Roundup) application on its endosymbiont Bradyrhizobium japonicum. DNA of bacteroids from isolated nodules was analysed for the presence of the transgenic 5-enolpyruvylshikimate-3-phosphate synthase (CP4-EPSPS) DNA sequence using polymerase chain reaction (PCR). To further assess the likelihood that the EPSPS gene may be transferred from the Roundup Ready (RR) soybean to B. japonicum, we have examined the natural transformation efficiency of B. japonicum strain 110spc4. Analyses of nodules showed the presence of the transgenic EPSPS DNA sequence. In bacteroids that were isolated from nodules of transgenic soybean plants and then cultivated in the presence of glyphosate this sequence could not be detected. This indicates that no stable horizontal gene transfer (HGT) of the EPSPS gene had occurred under field conditions. Under laboratory conditions, no natural transformation was detected in B. japonicum strain 110spc4 in the presence of various amounts of recombinant plasmid DNA. Our results indicate that no natural competence state exists in B. japonicum 110spc4. Results from field and laboratory studies indicate the lack of functional transfer of the CP4-EPSPS gene from glyphosate-tolerant soybean treated with glyphosate to root-associated B. japonicum.

  10. Post-dryout heat transfer and entrained droplet sizes at low pressure and low flow conditions

    Jeong, H.Y.; No, H.C.

    1997-01-01

    The entrainment mechanisms and the entrained droplet sizes with relation to the flow regimes are investigated. Through the analysis of many experimental post-dryout data, it is shown that the most probable flow regime near dryout or quench front is not annular flow but churn-turbulent flow when the mass flux is low. A correlation describing the initial droplet size just after the CHF position at low mass flux is suggested through regression analysis. The history-dependent post-dryout model of Varone and Rohsenow replaced by the Webb-Chen model for wall-vapor heat transfer is used as a reference model in the analysis. In the post-dryout region at low pressure and low flow, it is found that the suggested one-dimensional mechanistic model is not applicable when the vapor superficial velocity is very low. This is explained by the change of main entrainment mechanism with the change of flow regime. In bubbly or slug flow a number of tiny droplets generated from bubble burst become important in the heat transfer after dryout. Therefore, the suggested correlation is valid only in the churn-turbulent flow regime (j g * = 0.5∼4.5). It is also suggested that the droplet size generated from the churn-turbulent surface is dependent not only on the pressure but also on the vapor velocity. It turns out that the present model can predict the measured cladding and vapor temperatures within 20% and 25%, respectively

    Cash-based interventions (CBIs) increasingly are being used to deliver humanitarian assistance and there is growing interest in the cost-effectiveness of cash transfers for preventing undernutrition in emergency contexts. The objectives of this study were to assess the costs, cost-efficiency and cost-effectiveness in achieving nutrition outcomes of three CBIs in southern Pakistan: a 'double cash' (DC) transfer, a 'standard cash' (SC) transfer and a 'fresh food voucher' (FFV) transfer. Cash and FFVs were provided to poor households with children aged 6-48 months for 6 months in 2015. The SC and FFV interventions provided $14 monthly and the DC provided $28 monthly. Cost data were collected via institutional accounting records, interviews, programme observation, document review and household survey. Cost-effectiveness was assessed as cost per case of wasting, stunting and disability-adjusted life year (DALY) averted. Beneficiary costs were higher for the cash groups than the voucher group. Net total cost transfer ratios (TCTRs) were estimated as 1.82 for DC, 2.82 for SC and 2.73 for FFV. Yet, despite the higher operational costs, the FFV TCTR was lower than the SC TCTR when incorporating the participation cost to households, demonstrating the relevance of including beneficiary costs in cost-efficiency estimations. The DC intervention achieved a reduction in wasting, at $4865 per case averted; neither the SC nor the FFV interventions reduced wasting. The cost per case of stunting averted was $1290 for DC, $882 for SC and $883 for FFV. The cost per DALY averted was $641 for DC, $434 for SC and $563 for FFV without discounting or age weighting. These interventions are highly cost-effective by international thresholds. While it is debatable whether these resource requirements represent a feasible or sustainable investment given low health expenditures in Pakistan, these findings may provide justification for continuing Pakistan's investment in national social safety

    A mathematical model of the process of aerobic treatment of wastewater has been refined. It takes into account the interaction of bacteria, as well as of organic and biologically nonoxidizing substances under conditions of diffusion and mass transfer perturbations. An algorithm of the solution of the corresponding nonlinear perturbed problem of convection-diffusion-mass transfer type has been constructed, with a computer experiment carried out based on it. The influence of the concentration of oxygen and of activated sludge on the quality of treatment is shown. Within the framework of the model suggested, a possibility of automated control of the process of deposition of impurities in a biological filter depending on the initial parameters of the water medium is suggested.

    A self-similar burnout mode of solid polydisperse fuel is considered taking into consideration heat transfer between fuel particles, gases, and combustion chamber walls. A polydisperse composition of fuel is taken into account by introducing particle distribution functions by radiuses obtained for the kinetic and diffusion combustion modes. Equations for calculating the temperatures of particles and gases are presented, which are written for particles average with respect to their distribution functions by radiuses taking into account the fuel burnout ratio. The proposed equations take into consideration the influence of fuel composition, air excess factor, and gas recirculation ratio. Calculated graphs depicting the variation of particle and gas temperatures, and the fuel burnout ratio are presented for an anthracite-fired boiler.

    A soil-plant transfer study was performed using soil from a former uranium ore processing factory in South Bohemia. We present the results from greenhouse experiments which include estimates of the time required for phytoremediation. The accumulation of 226 Ra by different plant species from a mixture of garden soil and contaminated substrate was extremely variable, ranging from 0.03 to 2.20 Bq 226 Ra/g DW. We found differences in accumulation of 226 Ra between plants from the same genus and between cultivars of the same plant species. The results of 226 Ra accumulation showed a linear relation between concentration of 226 Ra in plants and concentration of 226 Ra in soil mixtures. On the basis of these results we estimated the time required for phytoremediation, but this appears to be too long for practical purposes.

    A soil-plant transfer study was performed using soil from a former uranium ore processing factory in South Bohemia. We present the results from greenhouse experiments which include estimates of the time required for phytoremediation. The accumulation of {sup 226}Ra by different plant species from a mixture of garden soil and contaminated substrate was extremely variable, ranging from 0.03 to 2.20 Bq {sup 226}Ra/g DW. We found differences in accumulation of {sup 226}Ra between plants from the same genus and between cultivars of the same plant species. The results of {sup 226}Ra accumulation showed a linear relation between concentration of {sup 226}Ra in plants and concentration of {sup 226}Ra in soil mixtures. On the basis of these results we estimated the time required for phytoremediation, but this appears to be too long for practical purposes.

    The spatial distribution and behaviour of the global fallout 137 Cs in the tropical, subtropical and equatorial soil-plant systems were investigated at several upland sites in Brazil selected according to their climate characteristics, and to the agricultural importance. To determine the 137 Cs deposition density, undisturbed soil profiles were taken from 23 environments situated between the latitudes of 02 o N and 30 o S. Sampling sites located along to the equator exhibited 137 Cs deposition densities with an average value of 219 Bq m -2 . Extremely low deposition densities of 1.3 Bq m -2 were found in the Amazon region. In contrast, the southern part of Brazil, located between latitudes of 20 o S and 34 o S, exhibited considerably higher deposition densities ranging from 140 Bq m -2 to 1620 Bq m -2 . To examine the 137 Cs soil-to-plant transfer in the Brazilian agricultural products, 29 mainly tropical plant species, and corresponding soil samples were collected at 43 sampling locations in nine federal states of Brazil. Values of the 137 Cs concentration factor plant/soil exhibited a large range from 0.020 (beans) to 6.2 (cassava). Samples of some plant species originated from different collecting areas showed different concentration factors. The 137 Cs content of some plants collected was not measurable due to a very low 137 Cs concentration level found in the upper layers of the incremental soils. Globally, the soil-to-plant transfer of 137 Cs can be described by a logarithmic normal distribution with a geometric mean of 0.3 and a geometric standard deviation of 3.9

    A mathematical and numerical model for the treatment of conjugate fluid flow and heat transfer problems in domains containing pure fluid, porous, and pure solid regions has been developed. The model is general and physically reasoned, and allows for local thermal non-equilibrium in the porous region. The model is developed for implementation on a simple collocated finite volume grid. Of particular novelty are the conditions implemented at the interfaces between porous regions, and those containing a pure solid or pure fluid. The model is validated by simulation of a three-dimensional porous plug problem for which experimental results are available. (author)

  4. When There Is No Welfare: The Income Packaging Strategies of Mothers Without Earnings or Cash Assistance Following an Economic Downturn

    Full Text Available The 1996 welfare reform law sought to reformulate single mothers’ income package, replacing cash welfare checks with paychecks. However, many single mothers have not been able to do that and have neither earnings nor cash assistance. Among a sample of single mothers in Los Angeles and southeast Michigan, we find that when single mothers lose jobs and do not receive cash assistance, they package income from a variety of sources (such as other public assistance programs and informal child support, find others in their social networks to pay their bills, or move in with others. However, their income packaging strategies are fraught with challenges. Benefits from certain public programs are difficult to secure; financial assistance from friends and family members can quickly vanish, particularly if a partner is deported or jailed; and doubling up with others often leads to living in crowded and unsafe conditions.

    The convection heat transfer coefficient is one of the evaluation indexes of the brake disc performance. The method used in this paper to calculate the convection heat transfer coefficient is a fluid-solid coupling simulation method, because the calculation results through the empirical formula method have great differences. The model, including a brake disc, a car body, a bogie and flow field, was built, meshed and simulated in the software FLUENT. The calculation models were K-epsilon Standard model and Energy model. The working condition of the brake disc was considered. The coefficient of various parts can be obtained through the method in this paper. The simulation result shows that, under 160 km/h speed, the radiating ribs have the maximum convection heat transfer coefficient and the value is 129.6W/(m2·K), the average coefficient of the whole disc is 100.4W/(m2·K), the windward of ribs is positive-pressure area and the leeward of ribs is negative-pressure area, the maximum pressure is 2663.53Pa.

    Issues about commercialization of space have been a growing concern in the past decade for the space community. This paper focuses on the work from a team of 51 students attending the Summer Session Program of the International Space University in Bremen, Germany. CASH 2021 (Commercial Access and Space Habitation) documents a plan that identifies commercial opportunities for space utilization that will extend human presence in space, and will chart the way forward for the next 20 years. The group selected four commercial sectors that show the most promise for the future: tourism, entertainment, space system service, assembly and debris removal, and research and development/production. The content of this document presents the results of their research. Historical activities in each of the commercial sectors are reviewed along with the current market situation. To provide a coherent background for future commercialization possibilities a scenario has been developed. This scenario includes a postulated upon ideal future and includes social, political and economic factors that may affect the space industry over the timeline of the study. The study also presents a roadmap, within the limited optimistic scenario developed, for the successful commercialization of space leading to future human presence in space. A broad range of commercially viable opportunities, not only within the current limits of the International Space Station, but also among the many new developments that are expected by 2021 are discussed.

    Hypersensitivity pneumonitis (HP) is a nonimmunoglobulin E-related immune-mediated parenchymal lung disease. A 45-year-old woman who was a lifelong nonsmoker with a six-month history of frequent episodes of cough and dyspnea was admitted to hospital. She had been working as a money counter for 20 years at a central bank. Bibasilar crackles on lung auscultation, ground-glass opacities and a mosaic pattern on high-resolution computed tomography, restrictive abnormality on pulmonary function tests and mild hypoxemia were the prominent findings. Bronchoalveolar lavage fluid analysis revealed a predominance of CD4-positive T cells, and she tested positive on her natural challenge test. She was diagnosed with subacute HP based on established criteria. She was advised to discontinue counting fresh banknotes. Prednisolone was commenced, then tapered to discontinue in the ensuing six months. Clinical and radiological improvement was achieved within two months. To the authors' knowledge, the present report is the first to describe 'hard cash HP', possibly caused by chipping dust or printing dye.

    Full Text Available This study aims to measure the degree of operational risk disclosure and examine its impact on operating cash flow of banks listed on the UAE Abu Dhabi Stock Exchange (ADX and Dubai Financial Market (DFM during the period 2003-2016. The authors conducted content analysis of the annual reports to measure the degree of operational risk disclosure. In addition, they used dynamic panel data regressions to analyze the impact of operational risk disclosure on the operating cash flow generated by the banks. The results show a low degree of operational risk disclosure for all UAE banks, both Islamic and conventional. In addition, the results show no association between the levels of disclosure of operational risk and cash flow for all banks, conventional and Islamic. Operational risk disclosure of Islamic banks has not been examined by any prior researchers. In addition, this paper examines the potential impact of operational risk disclosure on the operating cash flow generated by the banks.

  9. Your organization should consider a cash-balance pension plan.

    Science.gov (United States)

    Godwin, N H; Key, K G

    2000-08-01

    In recent years, a growing number of healthcare organizations have dropped the traditional defined-benefit pension plan and adopted cash-balance pension plans. A cash-balance pension plan generally allows employers to pay less in overall pension benefits and administration costs. A cash-balance pension plan pays benefits according to a predetermined formula based on an average of the employee's annual salary over his or her length of service. This provides recognizable benefits to younger employees but lower overall benefits to employees who have a long length of service. To assuage employees who may feel cheated out of the pension benefits they expected, employers that change to a cash-balance pension plan should consider offering higher guaranteed growth rates, advanced notification of the change to the new plan, and generous early-retirement options for employees with longer lengths of service.

    Acetonitrile (CH3 CN) is the simplest and one of the most stable nitriles. Reactions usually occur on the C≡N triple bond, while the C-H bond is very inert and can only be activated by a very strong base or a metal catalyst. It is demonstrated that C-H bonds can be activated by the cyano group under high pressure, but at room temperature. The hydrogen atom transfers from the CH3 to CN along the CH⋅⋅⋅N hydrogen bond, which produces an amino group and initiates polymerization to form a dimer, 1D chain, and 2D nanoribbon with mixed sp(2) and sp(3) bonded carbon. Finally, it transforms into a graphitic polymer by eliminating ammonia. This study shows that applying pressure can induce a distinctive reaction which is guided by the structure of the molecular crystal. It highlights the fact that very inert C-H can be activated by high pressure, even at room temperature and without a catalyst. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    In this paper, the contrast therapy of skin was numerically investigated by solving the conjugate heat transfer problem. A finite volume method based on the SIMPLE algorithm was adopted to solve the axisymmetric incompressible Navier-Stokes equations, coupled with an energy equation. These equations are strongly coupled with the Pennes bio-heat equation in order to consider the effect of blood perfusion rate. We investigated the thermal response of skin at some selected depths for various input temperature profiles of a stimulator for contrast therapy. From the numerical simulations, the regions with cold/hot threshold temperatures were found for five input temperature profiles. It was shown that the temperature varies mildly for different input profiles as the depth increases, owing to the Pennes effect. The input temperatures for effective hot/cold stimulation of dermis layer were found to be 47 degrees C and 7 degrees C, respectively. The present numerical results will be used for finding an optimal temperature profile of a stimulator for contrast therapy.

    Highlights: • We study the turbulent boundary layer with heat transfer by DNS. • Turbulent boundary layers with suddenly changing wall thermal conditions are observed. • The detailed turbulent statistics and structures in turbulent thermal boundary layer are discussed. • Turbulence models in LES and RANS are evaluated using DNS results. • LES and RANS are almost in good agreement with DNS results. -- Abstract: The objectives of this study are to investigate a thermal field in a turbulent boundary layer with suddenly changing wall thermal conditions by means of direct numerical simulation (DNS), and to evaluate predictions of a turbulence model in such a thermal field, in which DNS of spatially developing boundary layers with heat transfer can be conducted using the generation of turbulent inflow data as a method. In this study, two types of wall thermal condition are investigated using DNS and predicted by large eddy simulation (LES) and Reynolds-averaged Navier–Stokes equation simulation (RANS). In the first case, the velocity boundary layer only develops in the entrance of simulation, and the flat plate is heated from the halfway point, i.e., the adiabatic wall condition is adopted in the entrance, and the entrance region of thermal field in turbulence is simulated. Then, the thermal boundary layer develops along a constant temperature wall followed by adiabatic wall. In the second case, velocity and thermal boundary layers simultaneously develop, and the wall thermal condition is changed from a constant temperature to an adiabatic wall in the downstream region. DNS results clearly show the statistics and structure of turbulent heat transfer in a constant temperature wall followed by an adiabatic wall. In the first case, the entrance region of thermal field in turbulence can be also observed. Thus, both the development and the entrance regions in thermal fields can be explored, and the effects upstream of the thermal field on the adiabatic region are

    Full Text Available Surface-initiated graft atom transfer radical polymerization (ATRP of methyl methacrylate (MMA from self-assembled chitin nanofibers (CNFs was performed under dispersion conditions. Self-assembled CNFs were initially prepared by regeneration from a chitin ion gel with 1-allyl-3-methylimidazolium bromide using methanol; the product was then converted into the chitin nanofiber macroinitiator by reaction with α-bromoisobutyryl bromide in a dispersion containing N,N-dimethylformamide. Surface-initiated graft ATRP of MMA from the initiating sites on the CNFs was subsequently carried out under dispersion conditions, followed by filtration to obtain the CNF-graft-polyMMA film. Analysis of the product confirmed the occurrence of the graft ATRP on the surface of the CNFs.

    Z. Abbas

    Full Text Available An analysis is carried out to study the generalized slip condition and MHD flow of a nanofluid due to a contracting cylinder in the presence of non-linear radiative heat transfer using Buongiorno’s model. The Navier-Stokes along with energy and nanoparticle concentration equations is transformed to highly nonlinear ordinary differential equations using similarity transformations. These similar differential equations are then solved numerically by employing a shooting technique with Runge–Kutta–Fehlberg method. Dual solutions exist for a particular range of the unsteadiness parameter. The physical influence of the several important fluid parameters on the flow velocity, temperature and nanoparticle volume fraction is discussed and shown through graphs and table in detail. The present study indicates that as increase of Brownian motion parameter and slip velocity is to decrease the nanoparticle volume fraction.

    Full Text Available This research aimed to analyze the effect of leverage and asymmetry information on the firm value through cash holding as mediation variable. The populations of this research were all the firms which listed on the Indonesia Stock Exchange since 2012 – 2015. A sample of this research was saturated sample and census, consisted 56 firms related the population criteria.  This research used secondary data from the firm financial report through path analysis method. This research showed that leverage had a negative effect on the cash holdings, asymmetry information had a negative effect on the firm value through cash holding, and cash holding had a negative effect on the firm value.  With leverage and effect on cash, holding cannot affect the firm value, due to investor risk-averse, investor risk seeker, and neutral investor has their own point of view in assessing the company. Cash holdings can lead to asymmetric information that can lead to agency conflict that can affect a company's performance, so that indirectly, with the existence of asymmetry information had an effect on the declining the firm value. 

  4. Cash or Credit? Compensation in Psychology Studies: Motivation Matters

    Directory of Open Access Journals (Sweden)

    2017-05-01

    Full Text Available It is common practice for psychology researchers to recruit their sample of participants from the undergraduate student population. Participants are typically compensated with partial course credit or a monetary payment. The current study reveals that the motivation to participate in a study (cash versus course credit can relate to performance on a behavioral task of rewarded memory. In Experiment 1, undergraduate participants were recruited and compensated for their time with either partial course credit or cash. Potential performance-based cash rewards were earned during a rewarded memory task, where correct recognition of half the stimuli was worth a high reward and the other half a low reward. Memory for high reward items was better than low reward items, but only for the cash group. The credit group did not modulate their performance based on the value of the stimuli. In Experiment 2, undergraduates were compensated with partial course credit for their time and given the opportunity to earn a bonus credit for performance on a memory test. The findings were in line with the results from the credit group of Experiment 1, suggesting that the modulation of performance in the cash group of Experiment 1 cannot be accounted for by congruency between motivation to participate and reward for task performance. Of methodological importance, the findings indicate that recruiting and compensating participants with cash versus course credit may influence the results on a rewarded memory task. This factor should be taken into consideration in studies of reward motivation.

    The data on Radionuclide transfer parameters in the environments, which are used in radioecological models, are very necessary for setting release limits of radioactive effluent and assessing the radiation dose to Man related to the releases of radionuclides from nuclear facilities. They strongly depend on climatic, geographic, environmental and pedological conditions. For temperate environments, they are abundant and have been established fairly well. Meanwhile the literature data are still scare and dispersal for Tropical and Sub-tropical zones. Besides, the improvement of Environmental Transfer Models and Parameters is an important problem so that they may be adapted for Southeast Asian countries including Japan as environmental conditions and foodstuffs in this Region are significantly different from those in Europe and North America. The paper presents measurements results of the dry deposition velocities of atmospheric aerosols carrying 7 Be, 137 Cs radionuclides and measurements results of soil to plant transfer factors (TF) for 60 Co, 65 Zn, 85 ASr and 134 Cs resulted from the out door radiotracer experiments with large pots. The selected soil types (Podzolic, Ferralitic, Ferralic Acrisols, Eutric Fluvisols and Orthi-thionic Fluvisols soil) and the plants (rice, black bean, cabbage, lettuce, tomato, cucumber, carrot, white radish, potato) used for the research are the most common in Vietnam. The measured Vg values (cm/s) are in the range of 0.01 - 1.84 for 7 Be and 1.95 - 49.77 for 137 Cs. An analysis of the associated meteorological parameters showed some correlations between 7 Be Vg with humidity and 137 Cs Vg with wind velocity. More than 400 TF (edible part) values were determined and their dependences on some soil parameters have been shown. (author)

    2012-09-01

    Mercury (Hg) transference through an established and defined food web from an urbanized subtropical coastal lagoon (SE Gulf of California) was examined by using carbon and nitrogen stable isotope and Hg analyses. Concentrations of Hg in seawater (0.045-0.078 μg L(-1)), predominantly incorporated to the particulate fraction (60% of total), were lower than those found in highly contaminated coastal areas around the world (0.18-16 μg L(-1)). Although levels of Hg available for the biota (e.g., associated to the reactive and pyrite fractions; 0.11-0.15 μg g(-1)) were within of effects range-low (ER-L, 0.15-0.71 μg g(-1)) these concentrations represented from 46.6 to 67.0% of the total Hg pool that may be transferred through food web. The sequence of bio-accumulation of Hg in studied species was according with their functional guild: tertiary consumer (0.85-1.15 μg g(-1)) > secondary consumers (0.084-0.168 μg g(-1)) > primary consumers (0.014-0.160 μg g(-1)) > primary producers (0.016-0.056 μg g(-1)). Hg concentrations increased for each successive trophic position estimate through δ(15) N isotopic values, although these relationships showed differences between dry and rainy seasons (R(2) = 0.37 and R(2) = 0.39 between δ(15) N vs. Hg in organisms, respectively). We concluded that Hg is being positively transferred (biomagnification factor >1) through the studied food web probably enhanced by the favorable environmental conditions for Hg-methylation (e.g., fine sediments rich in organic matter, and environmental conditions changes of the redox, pH, and temperature) found in this urbanized coastal water, however, the study of processes methlylation and biomagnifcation of Hg need further investigations.

    Full Text Available The wetting behavior and interfacial microstructures of molten magnesium AZ61 alloy on the surface of two different Q235 and galvanized steel plates under the condition of cold metal transfer were investigated by using dynamic sessile drop method. The results show that the wetting behavior is closely related to the wire feed speed. Al-Fe intermetallic layer was observed whether the substrate is Q235 steel or galvanized steel, and the formation of Al-Fe intermetallic layer should satisfy the thermodynamic condition of such Mg-Al/Fe system. The wettability of molten AZ61 magnesium alloy is improved with the increase of wire feed speed whether on Q235 steel surface or on galvanized steel surface, good wettability on Q235 steel surface is due to severe interface reaction when wire feed speed increases, good wettability on galvanized steel surface is attributed to the aggravating zinc volatilization. When the wire feed speed is ≤10.5m·min-1, the wettability of Mg alloy on Q235 steel plate is better than on galvanized steel plate. However, Zn vapor will result in instability for metal transfer process.

    Lead (Pb) from spent gunshot and fishing sinkers is recognized as the main source of Pb poisoning among waterfowl. It is also suspected to directly pollute water and sediments, but no appropriate, comprehensive evaluation of this issue has so far been carried out. An experiment on Pb pellets in microcosms (n = 160) with two sediment types (mud and gravel), three water pH values (4, 7 and 9) and two wind levels (wind and windless simulation) was therefore run. Substantial differences in Pb transfer (measured with ICP-OES) between sediment types and pH levels of water were observed. Simulated wind conditions were a significant factor only for some variables and circumstances. The strongest Pb deposit to water and sediments occurred in mud microcosms with water of pH value of 4. Median pellet erosion during the experiment differed little between sediment types. The experiment revealed that Pb transfer from spent gunshot to the environment occurs only in specific environmental conditions. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2016-01-01

    To examine factors associated with food insecurity among urban older adults (65 years and older). Three hundred and fifty two older adults attending community centers in a neighborhood of Mexico City were surveyed for food insecurity, functional impairments, health and mental health status, cash-transfer assistance, socio-demographic characteristics, social isolation, and the built food environment. Having at least primary education and receiving cash-transfers were significantly associated with a lower probability of being moderately-severely food insecure (OR=0.478 and 0.597, respectively). The probability of moderate-severe food insecurity was significantly higher among elderly at risk of depression (OR=2.843), those with at least one activity of daily living impaired (OR=2.177) and those with at least one instrumental activity of daily living impaired (OR=1.785). Higher educational attainment and cash-transfers may have a positive influence on reducing food insecurity. Depression and functional limitations may increase the likelihood of food insecurity among older adults.

    The ability to propagate under anaerobic conditions is an essential and unique trait of brewer's or baker's yeast (Saccharomyces cervisiae). To understand the evolution of facultative anaerobiosis we studied the dependence of de novo pyrimidine biosynthesis, more precisely the fourth enzymic...... activity catalysed by dihydroorotate dehydrogenase (DHODase), on the enzymes of the respiratory chain in several yeast species. While the majority of yeasts possess a mitochondrial DHODase, Saccharomyces cerevisiae has a cytoplasmatic enzyme, whose activity is independent of the presence of oxygen. From....... We show that these two S. kluyveri enzymes, and their coding genes, differ in their dependence on the presence of oxygen. Only the cytoplasmic DHODase promotes growth in the absence of oxygen. Apparently a Saccharomyces yeast progenitor which had a eukaryotic-like mitochondrial DHODase acquired...

    Experiments have been carried out to study the heatup behavior of a single segmented reactor channel for Pressurized Heavy Water Reactor under submerged, partially submerged and exposed conditions. This situation may arise from a severe accident scenario of Pressurised Heavy Water Reactors where full or segmented reactor channels are likely to be disassembled and form a submerged debris bed. An assembly of electrical heater rod, simulating fuel bundle and channel components like Pressure Tube and Calandria Tube constitutes the segmented reactor channel. Heatup of this assembly is observed with respect to different water levels ranging from full submergence to totally exposed and power levels of 6-8 kW, typical to decay power level. It has been observed from the set of experiment that fuel bundle local dry out followed by heatup does not happen till the bundle is partially submerged. Temperature excursion of the bundle is evident when the bundle is exposed to steam-air environment. (orig.)

    For the class-E amplifier in a wireless power transfer (WPT) system, the design parameters are always determined by the nominal model. However, this model neglects the conduction loss and voltage stress of MOSFET and cannot guarantee the highest efficiency in the WPT system for biomedical implants. To solve this problem, this paper proposes a novel circuit model of the subnominal class-E amplifier. On a WPT platform for capsule endoscope, the proposed model was validated to be effective and the relationship between the amplifier's design parameters and its characteristics was analyzed. At a given duty ratio, the design parameters with the highest efficiency and safe voltage stress are derived and the condition is called 'optimal subnominal condition.' The amplifier's efficiency can reach the highest of 99.3% at the 0.097 duty ratio. Furthermore, at the 0.5 duty ratio, the measured efficiency of the optimal subnominal condition can reach 90.8%, which is 15.2% higher than that of the nominal condition. Then, a WPT experiment with a receiving unit was carried out to validate the feasibility of the optimized amplifier. In general, the design parameters of class-E amplifier in a WPT system for biomedical implants can be determined with the proposed optimization method in this paper.

    The effect discovered in studying a downward liquid-metal flow in vertical pipe and in a channel of rectangular cross section in, respectively, a transverse and a coplanar magnetic field is analyzed. In test blanket modules (TBM), which are prototypes of a blanket for a demonstration fusion reactor (DEMO) and which are intended for experimental investigations at the International Thermonuclear Experimental Reactor (ITER), liquid metals are assumed to fulfil simultaneously the functions of (i) a tritium breeder, (ii) a coolant, and (iii) neutron moderator and multiplier. This approach to testing experimentally design solutions is motivated by plans to employ, in the majority of the currently developed DEMO blanket projects, liquid metals pumped through pipes and/or rectangular channels in a transvers magnetic field. At the present time, experiments that would directly simulate liquid-metal flows under conditions of ITER TBM and/or DEMO blanket operation (irradiation with thermonuclear neutrons, a cyclic temperature regime, and a magnetic-field strength of about 4 to 10 T) are not implementable for want of equipment that could reproduce simultaneously the aforementioned effects exerted by thermonuclear plasmas. This is the reason why use is made of an iterative approach to experimentally estimating the performance of design solutions for liquid-metal channels via simulating one or simultaneously two of the aforementioned factors. Therefore, the investigations reported in the present article are of considerable topical interest. The respective experiments were performed on the basis of the mercury magneto hydrodynamic (MHD) loop that is included in the structure of the MPEI—JIHT MHD experimental facility. Temperature fields were measured under conditions of two- and one-sided heating, and data on averaged-temperature fields, distributions of the wall temperature, and statistical fluctuation features were obtained.

    To examine the extent to which financial assistance, in the form of subsidies for life-extending treatments (LETs) or cash payouts, distorts the demand for end-of-life treatments. A discrete choice experiment was administered to 290 patients with cancer in Singapore to elicit preferences for LETs and only palliative care (PC). Responses were fitted to a latent class conditional logistic regression model. We also quantified patients' willingness to pay to avoid and willingness to accept a less effective LET or PC-only. We then simulated the effects of various LET subsidy and cash payout policies on treatment choices. We identified three classes of patients according to their preferences. The first class (26.1% of the sample) had a strong preference for PC and were willing to give up life expectancy gains and even pay for receiving only PC. The second class (29.8% of the sample) had a strong preference for LETs and preferred to extend life regardless of cost or quality of life. The final class (44.1% of the sample) preferred LETs to PC, but actively traded off costs and length and quality of life when making end-of-life treatment choices. Policy simulations showed that LET subsidies increase demand for LETs at the expense of demand for PC, but an equivalent cash payout was not shown to distort demand. Patients with cancer have heterogeneous end-of-life preferences. LET subsidies and cash payouts have differing effects on the use of LETs. Policymakers should be mindful of these differences when designing health care financing schemes for patients with life-limiting illnesses. Copyright © 2016. Published by Elsevier Inc.

    Full Text Available Concentration and cooperation belong to the main attributes of the modern business life. Business competition makes the start of a new business more difficult. Just the moment of concentration and cooperation can make the break to the new business easier. This can be achieved by including new businesses into holding companies. Basically there are two ways how to do a business. These depend on whether company carries out many lines of business or on the amount of asset. The first way is to cover everything with one enterprise and thus to create one accounting unit. The second way is based on a foundation of a holding structure with subsidiaries and the holder on the top. In fact holding is a specific way how to cover business by many subsidiaries.The goal of this article is to describe specifics of a financial management of holdings when managing cash-flow. The focus is on reasons of holding structure and usage of both theoretical and other models of managing cash such as Baumol model, Miller-Orr model and Beránek model. As transfers within the holding organization belong to the main advantageous of holding, the way how to transfer finance from one subsidiary to other or from subsidiary to holder or reversely is handled here.

    The stability in physiological medium of polyplex- and lipoplex-type nonviral gene vectors was evaluated by detecting the conformational change of complexed plasmid DNA (pDNA) labeled simultaneously with fluorescein (energy donor) and X-rhodamine (energy acceptor) through fluorescence resonance energy transfer (FRET). Upon mixing with cationic components, such as LipofectAMINE, poly(L-lysine), and poly(ethylene glycol)-poly(L-lysine) block copolymer (PEG-PLys), the fluorescence spectrum of doubly labeled pDNA underwent a drastic change due to the occurrence of FRET between the donor-acceptor pair on pDNA taking a globular conformation (condensed state) through complexation. The measurement was carried out also in the presence of 20% serum, under which conditions FRET from condensed pDNA was clearly monitored without interference from coexisting components in the medium, allowing evaluation of the condensed state of pDNA in nonviral gene vectors under physiological conditions. Serum addition immediately induced a sharp decrease in FRET for the LipofectAMINE/pDNA (lipoplex) system, which was consistent with the sharp decrease in the transfection efficiency of the lipoplex system in serum-containing medium. In contrast, the PEG-PLys/pDNA polyplex (polyion complex micelle) system maintained appreciable transfection efficiency even in serum-containing medium, and FRET efficiency remained constant for up to 12 h, indicating the high stability of the polyion complex micelle under physiological conditions.

    Full Text Available The reliable estimation of buildings energy needs for cooling and heating is essential for any eventual thermal improvement of the envelope or the HVAC equipment. This paper presents an interesting method to evaluate the thermal performance of a massive wall by using the frequency-domain regression (FDR method to calculate CTF coefficients by means of the Fourier transform. The method is based on the EN ISO 13786 (2007 procedure by using the Taylor expansion for the elements of the heat matrix. Numerical results were validated through an experimental heating box with stochastic boundary conditions on one side of the wall representing real weather conditions and constant temperature profile on the other side representing the inside ambiance in real cases. Finally, a frequency analysis was performed in order to assess the validity and accuracy of the method used. The results show that development to the second order is sufficient to predict the thermal behavior of the studied massive wall in the range of frequencies encountered in the building applications (one hour time step. This method is useful for thermal transfer analysis in real weather conditions where the outside temperature is stochastic; it also allows the evaluation of the thermal performance of a wall through a frequency analysis.

    An experimental determination was made of heat transfer critical conditions in a circular channel, uniformly heated, and internally cooled by water in ascending forced convection, under a pressure slightly above atmospheric pressure. Measurements were made of water flow, pressure, electric power temperature and heating, and a systematic analysis was made of the system's parameters. The values obtained for the heat critical flux are circa 50% lower than those predicted by Becker and Biasi and this is accounted to flowing instabilities of thermo-hydrodynamic nature. It is suggested that the flowing channels of circuits aiming at the study of the boiling crisis phenomenon be expanded in its upper extremity, and that the coolant circulation be kept through a pump with a pressure X flow characteristic as vertical as possible

    For such high heat flux density as is released in the channels of EL3 reactor (2.10 6 kcal/m 2 h on the hottest point) cooling conditions have proved to be satisfactory, that is free from nucleate boiling. The arrangements provided for these tests and the technique used for measurements (of temperature particularly) are specified. Two fields have been investigated: in the former (forced convection without nucleate boiling) a good agreement is found with Colburn's formula. The influence of the ratio L/D is pointed out. The latter field is of forced convection with beginning of nucleate boiling; there the observed raise of the transfer coefficient has been shown occurring with some delay. (author) [fr

    In the current article, we have discussed the Poiseuille flow of an incompressible magnetohydrodynamic Jeffrey fluid between parallel plates through homogeneous porous medium using slip boundary conditions under the effect of heat transfer. The equations governing the fluid flow are modeled in Cartesian coordinate system. The energy equation is considered under the effects viscous dissipation and heat generation. Analytical solutions for the velocity and temperature profiles are obtained. The effects of the various involved parameters on the velocity and temperature profiles are studied and the results are presented through the graphs. It is observed from our analysis that, with increase of slip parameter and pressure gradient increase the velocity. The temperature is an increasing function of heat generation parameter, Brinkman number, thermal slip parameter and non-Newtonian fluid parameter.

    Solids moving with a gas stream in a pipeline can be found in many industrial processes, such as power generation, chemical, pharmaceutical, food and commodity transfer processes. A mass flow rate of the solids is important characteristic that is often required to be measured (and controlled) to achieve efficient utilization of energy and raw materials in pneumatic conveying systems. The methods of measuring the mass flow rate of solids in a pneumatic pipeline can be divided into direct and indirect (inferential) measurements. A thermal solids' mass flow-meter, in principle, should ideally provide a direct measurement of solids flow rate, regardless of inhomogeneities in solids' distribution and environmental impacts. One key issue in developing a thermal solids' mass flow-meter is to characterize the heat transfer between the hot pipe wall and the gas-solids dense phase flow. The Eulerian continuum modeling with gas-solid two phases is the most common method for pneumatic transport. To model a gas-solid dense phase flow passing through a heated region, the gas phase is described as a continuous phase and the particles as the second phase. This study aims to describe the heat transfer characteristics between the hot wall and the gas-solids dense phase flow in pneumatic pipelines by modeling a turbulence gas-solid plug passing through the heated region which involves several actual and crucial issues: selections of interphase exchange coefficient, near-wall region functions and different wall surface temperatures. A sensitivity analysis was discussed to identify the influence on the heat transfer characteristics by selecting different interphase exchange coefficient models and different boundary conditions. Simulation results suggest that sensitivity analysis in the choice of models is very significant. The simulation results appear to show that a combination of choosing the Syamlal-O'Brien interphase exchange coefficient model and the standard k-ɛ model along with

    1991-01-01

    Cash budgeting is generally considered to be an important part of resource management in all businesses. However, respondents to a survey of not-for-profit health care entities revealed that some 40 percent of the participants do not currently prepare cash budgets. Where budgeting occurred, the cash forecasts covered various time frames, and distribution of the document was inconsistent. Most budgets presented cash receipts and disbursements according to operating, investing, and financing activities--a format consistent with the year-end cash flow statement. By routinely preparing monthly cash budgets, the not-for-profit health care entity can project cash inflow/outflow or position with anticipated cash insufficiencies and surpluses. The budget should be compared each month to actual results to evaluate performance. The magnitude and timing of cash flows is much too critical to be left to chance.

    Full Text Available This paper based on the perspective of firm’s agency conflicts to examine the relationship between financial reporting quality and investment efficiency and to analyze the interaction effect between financial reporting and free cash flow on investment efficiency. We use 3,726 samples of Chinese listed firms during the period 2008–2012 to test the empirical models and find that financial reporting quality is negatively associated with both underinvestment and overinvestment. Further, we find that financial reporting quality is more strongly associated with overinvestment for firms with large free cash flow, which suggests that financial reporting quality can reduce information asymmetry arising from agency conflicts between the managers and investors. This paper extends the field of application of financial reporting quality and investment efficiency in the emerging capital markets in the world. Moreover, this is the first study that analyzes the interaction effect between financial reporting quality and free cash flow on investment efficiency.

    Full Text Available Cash flow ratios help financial users get relevant information about financial resources for a given time. Cash flow ratios are now used more than the traditional ones because it is more effective and justified. Cash flow based ratios are especially surprising because they do not only play a significant role in the credit rating of evaluation, but also forecast the failure of a corporation. In this study, we perform an empirical investigation on a company named CMC. From the study, it is clear that the liquidity and solvency positions of the company were moderate whereas the company maintained low profitability. On the other hand, the efficiency and sufficiency ratios of the study give us a new look on financial judgement.

    Full Text Available The financing decision is taken based on the expectations concerning the future cash-flows generated in the operating activity, which should provide coverage for the debt service and allow for an increase of the shareholders’ wealth. Still, the future cash-flows are affected by risk, which makes the sensitivity analysis a very important part of the decision process. The current research sets to evaluate the sensitivity of the payment capacity to variations of the payments for raw materials and consumables. The study employs 391 forecasted yearly cash-flow statements collected from 50 companies together with detailed information concerning the hypotheses of the forecasts. The results of the study allow for the establishment of benchmarks for the payment capacity’s sensitivity, the determination of the mechanisms through which the variation of payments for raw materials and consumables impacts the payment capacity, as well as the identification of the possible causes of such a variation.

    The hydration thermodynamics of the amino acid X relative to the reference G (glycine) or the hydration thermodynamics of a small-molecule analog of the side chain of X is often used to model the contribution of X to protein stability and solution thermodynamics. We consider the reasons for successes and limitations of this approach by calculating and comparing the conditional excess free energy, enthalpy, and entropy of hydration of the isoleucine side chain in zwitterionic isoleucine, in extended penta-peptides, and in helical deca-peptides. Butane in gauche conformation serves as a small-molecule analog for the isoleucine side chain. Parsing the hydrophobic and hydrophilic contributions to hydration for the side chain shows that both of these aspects of hydration are context-sensitive. Furthermore, analyzing the solute-solvent interaction contribution to the conditional excess enthalpy of the side chain shows that what is nominally considered a property of the side chain includes entirely nonobvious contributions of the background. The context-sensitivity of hydrophobic and hydrophilic hydration and the conflation of background contributions with energetics attributed to the side chain limit the ability of a single scaling factor, such as the fractional solvent exposure of the group in the protein, to map the component energetic contributions of the model-compound data to their value in the protein. But ignoring the origin of cancellations in the underlying components the group-transfer model may appear to provide a reasonable estimate of the free energy for a given error tolerance.

    Full Text Available Purpose - This paper aims to propose cash waqf (endowment to develop a conceptual model that can be utilised to extend microfinance for refugees. Design/methodology/approach - Qualitative method is used in this research. An extensive review of the literature has been conducted. Latest literature on refugees, microfinance has been critically examined beside the current cash waqf models. Findings - Empirical studies have shown that many refugees are equipped with marketable skills and talents that can be utilised to improve their socio-economic situations. The proposed model – cash waqf refugee microfinance fund (CWRMF – is structured to extend microfinance to potential refugee micro entrepreneurs. To address the lack of collateral, which is a requirement to gain any microfinance, CWRMF has been incorporated with a takaful unit (cooperation by which refugees may guarantee each other. Additionally, the model has also been structured to address the challenge of sustainability of the institution that would provide microfinance. Hence, a reserve fund has also been integrated into the model. Practical implications - CWRMF represents a potential model to be implemented by humanitarian non-governmental organisations (NGOs and aid agencies to support livelihood of refugees in particular for Muslim refugees. Positive outcome is expected from the implementation of this model. This is because of the various advantages of microfinance programs not only on refugees but also on concerned NGOs, host populations and donor parties. Additionally, this paper is a set of primarily thoughts aims to open the door wider for more researchers to explore the potential of cash waqf as one of the instruments to finance refugee microenterprises and business activities. Originality/value - Recently cash waqf has been into several models for socio-economic development and poverty alleviation.

    Several Central and Eastern European (CEE) countries require cost-utility analyses (CUAs) to support reimbursement formulary listing. However, CUAs informed by local evidence are often unavailable, and the cost-effectiveness of the several currently reimbursed biologicals is unclear. To estimate the cost-effectiveness as multiples of per capita GDP/quality adjusted life years (QALY) of four biologicals (infliximab, etanercept, adalimumab, golimumab) currently reimbursed in six CEE countries in six inflammatory rheumatoid and bowel disease conditions. Systematic literature review of published cost-utility analyses in the selected conditions, using the United Kingdom (UK) as reference country and with study selection criteria set to optimize the transfer of results to the CEEs. Prices in each CEE country were pro-rated against UK prices using purchasing power parity (PPP)-adjusted per capita GDP, and local GDP per capita/QALY ratios estimated. Central and Eastern European countries list prices were 144-333% higher than pro rata prices. Out of 85 CUAs identified by previous systematic literature reviews, 15 were selected as a convenience sample for estimating the cost-effectiveness of biologicals in the CEE countries in terms of per capita GDP/QALY. Per capita GDP/QALY values varied from 0.42 to 6.4 across countries and conditions (Bulgaria: 0.97-6.38; Czech Republic: 0.42-2.76; Hungary: 0.54-3.54; Poland: 0.59-3.90; Romania: 0.77-5.07; Slovakia: 0.55-3.61). While results must be interpreted with caution, calculating pro rata (cost-effective) prices and per capita GDP/QALY ratios based on CUAs can aid reimbursement decision-making in the absence of analyses using local data.

  19. Flow regime transition and heat transfer model at low mass flux condition in a post-dryout region

    International Nuclear Information System (INIS)

    Jeong, Hae Yong

    1996-02-01

    The post-dryout flow regime transition criterion from inverted annular flow (IAF) to agitated inverted annular flow (AIAF) is suggested based on the hyperbolicity breaking concept. The hyperbolicity breaking represents a bifurcation point where a sudden flow transition occurs. The hyperbolicity breaking concept is applied to describe the flow regime transition from IAF to AIAF by the growth of disturbance on liquid core surface. The resultant correlation has the similar form to Takenaka's empirical one. To validate the proposed model, it is applied to predict Takenake's experimental results using R-113 refrigerant with four different tube diameters of 3, 5, 7 and 10 mm. The proposed model gives accurate predictions for the tube diameters of 7 and 10 mm. As the tube diameter decreases, the differences between the predictions and the experimental results slightly increase. The flow regime transition from AIAF to dispersed flow (DF) is described by the drift flux model. It is shown that the transition criterion can be well predicted if the droplet sizes in dispersed flow are evaluated appropriately. Existing mechanistic post-dryout models result in fairly good predictions when the mass flux is high or when the film dryout occurs. However, the predictions by these models become poor at low mass flux at which the flow regime before dryout is believed to be churn-turbulent. This is because the constitutive relations and/or the imposed assumptions used in the models become erroneous at low mass flux. The droplet size predicted by the correlation used in the model becomes unrealistically large. In addition, the single phase vapor heat transfer correlation becomes invalid at low mass flux condition. To develop a mechanistic post-dryout model which is available at low mass flux condition, the entrainment mechanisms and the entrained droplet sizes with relation to the flow regimes are investigated. Through the analysis of many experimental post-dryout data, it is shown that

  2. Heat and mass transfer in turbulent chemically nonequilibrium flow in the tube with boundary second kind conditions. The section with the stabilized heat and mass transfer

    Kritsuk, E.L.; Mishina, L.V.; Shegidevich, L.N.

    1986-01-01

    The hydrodynamically stabilized chemically nonequilibrium turbulent flow in a tube with the inert impermeable surface and constant specific heat flow on the wall is considered. The reversible homogeneous reaction of nitrogen dioxide dissociation 2NO 2 ↔ 2NO+O 2 takes place in the flow. Chemically equilibrium flow with homogeneous profile of temperature and concentration arrives into the channel inlet. After application of simplifying assumptions, the expressions for characteristics of heat and mass transfer have been written down, which are valid in the whole range of the flow parameter variation from frozen up to chemically equilibrium flow. An integral transformation method is suggested for a radial coordinate which allows a wall region to be extended, thereby essentially extending the step of integration. A solution in quadratures has been obtained for the heat and mass transfer problem in an inert fluid flow for the developed process section. The elimination method has been employed to solve the boundary-value second-kind problem for the function governing heat and mass transfer in a chemically nonequilibrium turbulent flow over the developed heat and mass transfer section. The results of calculations are presented

  18. On the radiative transfer problem in a spherical medium subject to Fresnel's reflective boundary conditions

    International Nuclear Information System (INIS)

    Mohammed, M.H.H.

    2012-01-01

    Radiation transfer problem for anisotropic scattering in a spherical homogeneous, turbid medium with angular dependent (specular) and diffuse reflecting boundary is considered. The angular dependent reflectivity of the boundary is considered as Fresnel's reflection probability function. The solution of the problem containing an energy source in a medium of specular and diffuse reflecting boundaries is given in terms of the solution of the source-free problem. The source-free problem for anisotropic scattering through a homogeneous solid sphere and two concentric spheres is solved by using the Pomraning- Eddington approximation method. This method transform the integro-differential equation into two differential equations for the radiance g (x) and net flux q (x) which has an analytical solution in terms of the modified Bessel function. Two different weight functions are used to verify the boundary conditions and so, find the solution constants. The partial heat fluxes at the boundaries of a solid sphere and spherical shell of transparent and reflecting boundaries are calculated. The media are taken with or without internal black-body radiation. The calculations are carried out for various values of refractive index and different radii. The results are compared with those of the Galerkin technique

    In this article, the mixed convective heat transfer to Sisko fluid over a radially stretching surface in the presence of convective boundary conditions is investigated. The viscous dissipation and thermal radiation effects are also taken into account. The suitable transformations are applied to convert the governing partial differential equations into a set of nonlinear coupled ordinary differential equations. The analytical solution of the governing problem is obtained by using the homotopy analysis method (HAM). Additionally, these analytical results are compared with the numerical results obtained by the shooting technique. The obtained results for the velocity and temperature are analyzed graphically for several physical parameters for the assisting and opposing flows. It is found that the effect of buoyancy parameter is more prominent in case of the assisting flow as compared to the opposing flow. Further, in tabular form the numerical values are given for the local skin friction coefficient and local Nusselt number. A remarkable agreement is noticed by comparing the present results with the results reported in the literature as a special case.

    Nanofluids retain noteworthy structure that have absorbed attentions of numerous investigators because of their exploration in nanotechnology and nanoscience. In this scrutiny a mathematical computation of 2D flows of Maxwell nanoliquid influenced by a stretched cylinder has been established. The heat transfer structure is conceded out in the manifestation of thermal radiation and heat source/sink. Moreover, the nanoparticles mass flux condition is engaged in this exploration. This newly endorsed tactic is more realistic where the conjecture is made that the nanoparticle flux is zero and nanoparticle fraction regulates itself on the restrictions consequently. By utilizing apposite conversion the governing PDEs are transformed into ODEs and then tackled analytically via HAM. The attained outcomes are plotted and deliberated in aspect for somatic parameters. It is remarked that with an intensification in the Deborah number β diminish the liquid temperature while it boosts for radiation parameter Rd . Furthermore, the concentration of Maxwell liquid has conflicting impact for Brownian motion Nb and thermophoresis parameters Nt .

  2. Improved inter-assembly heat transfer modeling under low flow conditions for the Super System Code (SSC)

    International Nuclear Information System (INIS)

    Horak, W.C.; Guppy, J.G.

    1984-01-01

    The Super System Code (SSC) was developed at the Brookhaven National Laboratory (BNL) for the thermal hydraulic analysis of natural circulation transients, operational transients, and other system wide transients in nuclear power plants. SSC is a generic, best estimate code that models the in-vessel components, heat transport loops, plant protection systems and plant control systems. SSC also simulates the balance of plant when interfaced with the MINET code. SSC has been validated against both numerical and experimental data bases and is now used by several outside users. An important area of interest in LMFBR transient analysis is the prediction of the response of the reactor core under low flow conditions, such as experienced during a natural circulation event. Under these circumstances there are many physical phenomena which must be modeled to provide an adequate representation by a computer code simulation. The present version of SSC contains numerous models which account for most of the major phenomena. However, one area where the present model in SSC is being improved is in the representation of heat transfer and buoyancy effects under low flow operation. To properly improve the present version, the addition of models to represent certain inter-assembly effects is required

    Cash flows are incrementally useful to earnings in security valuation mainly when earnings quality is low. This suggests that when earnings quality decreases, analysts will be more likely to supplement their earnings forecasts with cash flow estimates. Contrary to this prediction, we find that analysts do not disclose cash flow forecasts when the quality of earnings is low. This is because cash flow forecast accuracy depends on the accuracy of the accrual estimates and the precision of accrua...
