Abstract

Maternal dietary habits influence maternal and foetal health, representing a pathway for intervention to maximise pregnancy outcomes. Advice on energy intake is provided on a trimester basis, with no additional calories required in the first trimester and an additional 340?kcal?d^?1 and 452?kcal?d^?1 needed for the second and third trimesters. Energy intake depends on pre-gravid body mass index (BMI); underweight women are recommended an increase of 150, 200 and 300?kcal?d^?1 during the first, second and third trimester, normal weight women an increase of 0, 350 and 500?kcal?d^?1 and obese women an increase of 0, 450 and 350?kcal?day^?1. The recommendations for carbohydrate and protein intake are 175?g?d^?1 and 0.88–1.1?g?kgBM?d^?1, with no change to fat intake. The number of pre-gravid obese women is rising; therefore, we need to regulate weight in women of childbearing age and limit gestational weight gain to within the recommended ranges [overweight women 6.8–11.3?kg and obese women 5.0–9.1?kg]. This can be achieved using nutritional interventions, as dietary changes have been shown to help with gestational weight management. As pregnancy has been identified as a risk factor for the development of obesity, normal weight women should gain 11.5–16.0?kg during pregnancy. While some research has shown that dietary interventions help to regulate gestational weight gain and promote postpartum weight loss to some extent, future research is needed to provide safe and effective guidelines to maximise these effects, while benefitting maternal and foetal health.  相似文献   

Critically reflexive dialogue and praxis: Academic/practitioner reflections throughout a formative evaluation of Circles® USA     

Mary Jane Collier  Brandi Lawless 《Journal of Applied Communication Research》2016,44(2):156-173

Reflections about the use of critically reflexive praxis by academic/practitioners are offered based on a case study of a formative evaluation of Circles^® USA, a nonprofit organization coordinating initiatives across the U.S. working to move families out of poverty. Critically reflexive praxis is theorized as featuring several themes including acknowledging different levels of context, critical dialogue with collaborators, engaging cultural difference and intersectionalities, problematizing power relations and relationships among researchers and collaborators, and occurring throughout the research project. Examples of critical dialogic reflexivity and navigating common tensions that emerge throughout such community engagement projects are detailed during three phases: planning and design; fieldwork and interviews; and outcomes, applications, and implications.  相似文献   

The effect of modifiers on the stability of a vinyl acetate/ethylene copolymer dispersion     

Jane L. Down 《文物保护研究》2016,61(1):26-45

This paper examines the effect of modifiers on the stability of a vinyl acetate/ethylene copolymer dispersion adhesive upon aging. Eighteen common modifiers were added to a well-characterized vinyl acetate/ethylene copolymer dispersion (Dur-O-Set^® E-150) in known concentrations and dry-film samples were subjected to 16–17 years of dark aging and seven to eight years of light aging. Yellowing, pH, gloss, swelling, cohesive strength, and flexibility were monitored for changes upon aging. Generally, the neat Dur-O-Set^® E-150 (no additives) was found to become acidic on aging, but was fairly resistant to yellowing. It also swelled substantially in toluene, was of high gloss, medium strength, and flexible, and remained so on aging. No modifier was found to improve these properties. Various solvents, wetting agents, and thickeners did not alter the properties by much, while plasticizers, freeze-thaw stabilizer, glycerin, and certain fillers had a more negative effect.  相似文献   

Dialogue in conservation decision-making     

Jane Henderson  Tanya Nakamoto 《文物保护研究》2016,61(3):67-78

An analysis of the impact of stakeholder consultation during the conservation decision-making processes is presented. Defining and finding opportunities for stakeholder communication within conservation work is an ethical necessity when working with cultural heritage, but the limits and practice of this necessity are less clear. Case studies are used to explore which aspects of the conservation process stakeholders are most likely to be consulted about, and reviews the impact of their views. It asks whether conservators have a preference in which decisions they are prepared to share with stakeholders across three aspects of conservation: the initial appraisal, treatment and the display or storage. Where consultation relates to treatment, conservators are more likely to fall back on their own technical authority except when those consulted are regarded as fellow professionals. Other categories of stakeholder such as artists, originating communities, and religious groups were found to be more constructively consulted on the understanding of the object and on care related to display and storage. Conservators should be offered more explicit guidance on the ethics of consultation, the aspects of consultation that they should engage with and on the ethical ways to deal with conflict arising from consultation.  相似文献   

Effective preservation decision strategies     

Jane Henderson  Robert Waller 《文物保护研究》2016,61(6):308-323

Decisions about preservation issues are made both deliberatively and unconsciously. Heuristics operate as intuitive processes which are rapid and can be reliable and effective. Deliberative decisions require time to complete and can be described by an analytic-deliberative model. The characteristics of these two processes and their relevance to preventive conservation decision-making are discussed. Each of these two processes has its strengths and weaknesses. People naturally make decisions and utilise a range of strategies without necessarily having insights into the process. This paper provides a frame to help examine, describe, and reflect upon our own and others’ decision-making in order to improve both processes and outcomes.  相似文献

Accelerometer data requirements for reliable estimation of habitual physical activity and sedentary time of children during the early years - a worked example following a stepped approach     

Daniel D. Bingham  Silvia Costa  Stacy A. Clemes  Ash C. Routen  Helen J. Moore  Sally E. Barber 《Journal of sports sciences》2016,34(20):2005-2010

This study presents a worked example of a stepped process to reliably estimate the habitual physical activity and sedentary time of a sample of young children. A total of 299 children (2.9 ± 0.6 years) were recruited. Outcome variables were daily minutes of total physical activity, sedentary time, moderate to vigorous physical activity and proportional values of each variable. In total, 282 (94%) provided 3 h of accelerometer data on ≥1 day and were included in a 6-step process: Step-1: determine minimum wear-time; Step-2: process 7-day-data; Step-3: determine the inclusion of a weekend day; Step-4: examine day-to-day variability; Step-5: calculate single day intraclass correlation (ICC) (2,1); Step-6: calculate number of days required to reach reliability. Following the process the results were, Step-1: 6 h was estimated as minimum wear-time of a standard day. Step-2: 98 (32%) children had ≥6 h wear on 7 days. Step-3: no differences were found between weekdays and weekend days (P ≥ 0.05). Step-4: no differences were found between day-to-day variability (P ≥ 0.05). Step-5: single day ICC’s (2,1) ranged from 0.48 (total physical activity and sedentary time) to 0.53 (proportion of moderate to vigorous physical activity). Step-6: to reach reliability (ICC = 0.7), 3 days were required for all outcomes. In conclusion following a 7 day wear protocol, ≥6 h on any 3 days was found to have acceptable reliability. The stepped-process offers researchers a method to derive sample-specific wear-time criterion.  相似文献   

“But it doesn’t come naturally”: how effort expenditure shapes the benefit of growth mindset on women’s sense of intellectual belonging in computing     

Jane G. Stout  Jennifer M. Blaney 《Computer Science Education》2017,27(3-4):215-228

Research suggests growth mindset, or the belief that knowledge is acquired through effort, may enhance women’s sense of belonging in male-dominated disciplines, like computing. However, other research indicates women who spend a great deal of time and energy in technical fields experience a low sense of belonging. The current study assessed the benefits of a growth mindset on women’s (and men’s) sense of intellectual belonging in computing, accounting for the amount of time and effort dedicated to academics. We define “intellectual belonging” as the sense that one is believed to be a competent member of the community. Whereas a stronger growth mindset was associated with stronger intellectual belonging for men, a growth mindset only boosted women’s intellectual belonging when they did not work hard on academics. Our findings suggest, paradoxically, women may not benefit from a growth mindset in computing when they exert a lot of effort.  相似文献   

“Montrose” child life protection unit: A treatment and assessment model in child abuse intervention     

Jane Brazier B.A. Dip. Social Work  Alison A. Davis RGN  RMN RCHN DCHN MCN  Jan Shier B.A. Applied Science 《Child abuse & neglect》1982,6(4):389-394

In New South Wales, Australia, the Department of Youth and Community Services is empowered by statute to deal with cases of child abuse and neglect. Its child protection services include the Montrose Child Life Protection Unit which is designed to support and complement the work of both the Intake Service, Field Service and most importantly the work of child protective facilities in the community. The service has intake crisis counselling and call out resources; maintains a central register; provides a facility for crisis residential care for children and families, diagnostic assessment, and a day programme. The emphasis in service delivery in New South Wales in the area of child protection is on multidisciplinary intervention. The Department of Youth and Community Services is involved in promoting interagency cooperation and co-ordination. Over and above a philosophy that underlies service delivery is the Montrose Unit's involvement in sensitising the community to the difficult and often demanding role of parenting. Montrose represents an attempt to create an environment where parenting myths can be examined from a reality base and strategies implemented for reeducation.  相似文献
