AbstractMaternal 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

The position of the case method in MBA education is discussed, followed by an examination of the nature of business cases, benefits to be derived from the case method, roles for students and instructors in case-oriented courses, and issues concerning integration of cases into an overall course design. It is argued that case analysis helps students to develop the kinds of skills that are essential to success in business organizations: identification and analysis of complex business problems, application of judgment in developing solutions, interactive problem-solving, and persuasive presentation of conclusions. The case method presents special challenges to both the instructor and the student. Both are required to sacrifice their traditional roles. The instructor is a facilitator rather than a content expert, and the student must assume a highly active role, providing the substantive content for the discussion. Both instructor and student are well rewarded for their adjustments by the many benefits of the case method. 相似文献

As academic health sciences libraries assume larger roles in informatics instruction within medical school curricula, librarians are challenged to develop useful and accurate measures for assessing the effectiveness of instructional approaches. The need for this evaluation has intensified as medical schools increase their emphasis on integration of curriculum content and shift to competency-based education and assessment of medical students. This paper reports on a pilot project developed at Dahlgren Memorial Library, Georgetown University Medical Center, for two courses using an instructional intervention and tailored assignment for assessing student competencies. 相似文献

This paper deals with several aspects of R & D activity in Israel's manufacturing industries on three levels — the economy, industrial branch and the firm. Relative to other industrial countries, Israel is characterized by a high share of R & D expenditure in GNP but a low level of industrial R & D. If we take registered patents as an indicator of R & D output no significant correlation is found between this measure and expenditure on R & D; this may point to a low level of success or to the nature of R & D being directed more to small improvements of existing products and processes than to new inventions. An inter-industry analysis shows that R & D expenditure is positively correlated with average firm size and capital per employee and negatively correlated with concentration ratio. A positive correlation was also found with respect to increase in sales and export per employee but not with the rate of growth of export. Although most R & D is performed by large companies there is no significant correlation between R & D expenditure and firm's size among firms engaged in R & D, nor between R & D expenditure and firm's profitability. Concerning the relationship between domestic R & D and imports of technology a tentative conclusion is that Israel does not derive sufficient benefit from the international stock of knowledge. 相似文献

OBJECTIVE: Sexual offenders tend to hold attitudes and beliefs which minimize and justify their offending behavior. It was hypothesized that distorted thinking supporting sexual offending and blame attribution would differ depending on the offence characteristics of different groups of sexual offenders. METHOD: Two groups of sexual offenders separated on the basis of the age of their victims (sex offenders against children, 36; sex offenders against adults, 30) were compared on measures of cognitive distortions relating to sex with children and rape and a measure of blame attribution which assesses external, mental element, and guilt feeling attributions. RESULTS: Child sexual offenders endorsed more cognitive distortions relating to sex with children, but there were no group differences in cognitive distortions relating to rape. Those who offended against adults reported more external attributions and child offenders reported more guilt feeling attributions. Mental element attribution related to alcohol intoxication and use of violence in the offence, but was not related to group differences. CONCLUSIONS: Results are interpreted as suggesting that child sex offenders support their offending by more enduring distorted cognitions, while those who offend against adults use blame attributions associated with the particular offence. 相似文献
