Nature Publishing Group and the Alliance for Cellular Signaling formed a partnership in 2001 to develop a comprehensive website for researchers in the field of cellular signalling. This website aimed to evolve the traditional form of publication (an article with supplementary information and links) into something that made better use of web and database technologies, and provided more value to scientists. This article gives an overview of the project, some of the thinking behind it, and how it has developed.  相似文献

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

Relationship violence is a salient concern on college campuses today, and psychoeducational groups may be an appropriate prevention format. This article describes a study measuring the impact of college student participation in the HEART (Help End Abusive Relationships Today) program, a series of group sessions designed to increase knowledge and awareness of relationship violence. Findings indicated significant changes for group participants postintervention. Implications and recommendations for college counselors are discussed.  相似文献

ABSTRACT

This study aimed to assess the effect of playing surface (Natural [NT] and Artificial [AT] Turf) on the fatigue response to a soccer-specific exercise protocol (SSEP). Eighteen male soccer players completed the SSEP on NT and AT with pre-, post-, and 48 h post-assessments of eccentric knee flexor (eccKF) and concentric knee extensor peak torque (PT), peak countermovement (CMJ) and squat jump (SJ) height, and Nordic hamstring break angle. No significant main effects for surface or any surface and time interactions were observed for any of the outcome measures, except for eccKF PT recorded at 3.14 rad·s-1, which was significantly lower 48 h post-trial in the AT condition (AT = 146.3 ± 20.4 Nm; NT = 158.8 ± 24.7 Nm). Main effects for time were observed between pre- and post-trial measures for eccKF PT at all angular velocities, Nordic break angle, CMJ and SJ height. Nordic break angle, and both CMJ and SJ height were significantly impaired 48 h post-trial when compared to pre-trial. The findings of the current study suggest surface dependent changes in eccKF PT which may have implications for recovery and subsequent performance after competition on AT.  相似文献

For this talk, Marks was tasked with summarizing the important trends in scholarly publishing in 45 minutes. The speaker reflected on the rapid changes that have occurred in journal publishing, which followed more than 300 years of relatively slow progress. Marks discussed key technology trends such as data curation, Open Access (OA) mandates, and the changes occurring in the global landscape of scholarly communications and library budgets. Wolters Kluwer Health has been responding to these trends with new publishing experiments including a Platinum OA model in emerging markets. Marks discussed the ways that publishers and libraries need to alter their traditional practices and instill a focus on their customers and communities.  相似文献

Using participatory action research (PAR), this paper explores the ethical practice of students engaged in practitioner research in a higher education context. Using narrative enquiry, the paper explores the participants’ experiences of practitioner research, including ethical dilemmas that resulted from a conflict of values between the practitioner and research roles. We postulate a multi-dimensional approach to ethical practice known as ‘ethical posture’ emerging from our consideration of conceptions of inquiry that resulted in contrasting ethical behaviour.  相似文献

Recent education policy places a heavy emphasis on parents in relation to students' success at school. This paper explores how parents and teachers account for school success. Using membership categorisation analysis, it interrogates data collected in different interview situations across sites over a period of 20 years. The analysis shows how parents and teachers use talk as moral work to conversationally constitute particular agreed versions of the category ‘parent’. This category is interactively assembled through the use of category-bound attributes that construct deficit discourses of parents that explain student achievement. The analysis demonstrates that parents are complicit with teachers in producing versions of being a good parent wherein they are held responsible for their children's school success and that minimises the responsibility of the school. These findings raise questions both about who is responsible for schooling and about current contradictory policy emphases on parent and teacher responsibility for school success.  相似文献
