A double-blind randomized controlled trial of n-3 long-chain polyunsaturated fatty acid (n-3 LCPUFA) supplementation or matching placebo during third trimester of pregnancy was conducted within the COPSAC2010 mother-child cohort consisting of 736 women and their children. The objective was to determine if maternal n-3 LCPUFA pregnancy supplementation affects offspring neurodevelopment until 6 years. Neurodevelopment was evaluated in 654 children assessing age of motor milestone achievement, language development, cognitive development, general neurodevelopment, and emotional and behavioral problems. Maternal n-3 LCPUFA supplementation during pregnancy improved early language development and reduced the impact of emotional and behavioral problems. The n-3 LCPUFA supplementation was in boys associated with the earlier achievement of gross motor milestones, improved cognitive development, and a reduced impact of emotional and behavioral problems. 相似文献

AbstractThe present study used a Solomon four-group quasi-experimental design to examine the short-term effect of a large-scale national financial education program on children’s knowledge and skills in responsible spending and performing transactions effectively. Our study included a representative sample of Dutch pupils in the fifth grade of primary school (N?=?2,650). Controlling for different children-specific characteristics, results showed that the program increased pupils’ knowledge and skills scores in performing transactions effectively, but not in responsible spending. The insights gained from the present study show how financial education programs that enable children to immediately apply what they learn in practice can improve children’s knowledge and skills regarding certain financial competencies. 相似文献

For a valid determination of a rower’s mechanical power output, the anterior–posterior (AP) acceleration of a rower’s centre of mass (CoM) is required. The current study was designed to evaluate the accuracy of the determination of this acceleration using a full-body inertial measurement units (IMUs) suit in combination with a mass distribution model. Three methods were evaluated. In the first two methods, IMU data were combined with either a subject-specific mass distribution or a standard mass distribution model for athletes. In the third method, a rower’s AP CoM acceleration was estimated using a single IMU placed at the pelvis.Experienced rowers rowed on an ergometer that was placed on two force plates, while wearing a full-body IMUs suit. Correspondence values between AP CoM acceleration based on IMU data (the three methods) and AP CoM acceleration obtained from force plate data (reference) were calculated. Good correspondence was found between the reference AP CoM acceleration and the AP CoM accelerations determined using IMU data in combination with the subject-specific mass model and the standard mass model (intraclass correlation coefficients [ICC] >?0.988 and normalized root mean square errors [nRMSE]?3.81%). Correspondence was lower for the AP CoM accelerations determined using a single pelvis IMU (0.877?Based on these results, we recommend determining a rower’s AP CoM acceleration using IMUs in combination with the standard mass model. Finally, we conclude that accurate determination of a rower’s AP CoM acceleration is not possible on the basis of the pelvis acceleration only. 相似文献

This article reports on findings from a research project on interdisciplinary collaboration between mainstream school teachers and special school teachers. The aim of the research project has been to examine the knowledge of special school teachers and how this knowledge can contribute to the development of an inclusive learning environment in mainstream schools. Not as a simple task of transferring knowledge, but as a process of transforming knowledge through interdisciplinary collaboration and co-teaching. The design of the study is inspired by the notion of participation within action research as a research approach. Thus the thick data generated from reflective activities in the study design are analysed within a narrative and practice directed strategy of analysis. 相似文献

Mechanical power output is a key performance-determining variable in many cyclic sports. In rowing, instantaneous power output is commonly determined as the dot product of handle force moment and oar angular velocity. The aim of this study was to show that this commonly used proxy is theoretically flawed and to provide an indication of the magnitude of the error. To obtain a consistent dataset, simulations were performed using a previously proposed forward dynamical model. Inputs were previously recorded rower kinematics and horizontal oar angle, at 20 and 32 strokes?min?1. From simulation outputs, true power output and power output according to the common proxy were calculated. The error when using the common proxy was quantified as the difference between the average power output according to the proxy and the true average power output (P?residual), and as the ratio of this difference to the true average power output (ratiores./rower). At stroke rate 20, P?residual was 27.4 W and ratiores./rower was 0.143; at stroke rate 32, P?residual was 44.3 W and ratiores./rower was 0.142. Power output in rowing appears to be underestimated when calculated according to the common proxy. Simulations suggest this error to be at least 10% of the true power output. 相似文献

This article examines management of the Freedom of Information Act and how Federal information policy changed during the eight years of the Reagan administration. The article analyzes the 1986 F.O.I.A. amendments and, particularly, the fee waiver provisions; examines the varying congressional and executive interpretations of these amendments; and considers the Reagan administration's skillful use of traditional managerial tools in new ways to shape its policy and implement its philosophy. 相似文献

In Western societies scientists are increasingly expected to seek media exposure and cooperate with industry. Little attention
has been given to the way such expectations affect the role of scientific experts in society. To investigate scientists’ own
perspectives on these issues eight exploratory, in-depth interviews were conducted in Denmark with reputable nutrition scientists.
Additionally, eight interviews were held with ‘key informants’ from the field of nutrition policy. It was found that nutrition
scientists experience two dilemmas: first, between their aspiration to make a collective impact on public health and the powerful
incentives of each to appear frequently in the media with new messages; second, between their need to cooperate with the food
industry for financial reasons and their fear that this may compromise their independence and scientific integrity. It is
argued that the dilemmas identified in this study should be dealt with openly by the relevant groups of scientists. 相似文献

Access to government records is increasingly shifting to a nether world-governed neither by the FOIA and the Privacy Act, nor by an executive order on classification. Instead, new categories of records, labeled “sensitive but unclassified,” “for official use only,” or “critical infrastructure information,” are being created in a variety of agencies, and are governed by agency regulations. Statutory authority is found in a number of separate laws, such as the Homeland Security Act and the Aviation and Transportation Security Act. These categories can be assigned by agency officials, contractors, or those in the private sector who originated the records; many records categorized this way are not subject to appeal or review by agencies or the courts, or to any automatic “declassification” process that has applied to documents withheld under the FOIA or subject to classification. Trends toward increased secrecy at all levels of government have become sufficiently alarming that individuals across the political spectrum have begun to speak out, and members of the access community (e.g., newspaper editors and public interest groups) have formed coalitions to focus debate on the need to rethink the balance of access with privacy and records protection, and to lobby actively for reinstatement of principles of access that have governed records policy for the past 35 years. 相似文献
