Effectiveness of a kindergarten-based intervention to increase vegetable intake and reduce food neophobia amongst 1-year-old children: a cluster rand…
2021
Background: Children’s first years of life are crucial to their future health. Studies show that a varied diet with a high intake of vegetables is positive in several domains of health. The present low vegetable intake amongst children is, therefore, a concern. Food neophobia is a common barrier to vegetable intake in children. As most Norwegian children attend kindergarten from an early age, kindergartens could contribute to the prevention of food neophobia and the promotion of vegetable intake. Objective: The aim of this study was to assess the effect of a cluster randomised trial amongst 1-year-old children in kindergarten to reduce food neophobia and promote healthy eating. Methods: Kin…
Numerical Simulations of the Flow Field of a Submerged Hydraulic Jump over Triangular Macroroughnesses
2021
The submerged hydraulic jump is a sudden change from the supercritical to subcritical flow, specified by strong turbulence, air entrainment and energy loss. Despite recent studies, hydraulic jump characteristics in smooth and rough beds, the turbulence, the mean velocity and the flow patterns in the cavity region of a submerged hydraulic jump in the rough beds, especially in the case of triangular macroroughnesses, are not completely understood. The objective of this paper was to numerically investigate via the FLOW-3D model the effects of triangular macroroughnesses on the characteristics of submerged jump, including the longitudinal profile of streamlines, flow patterns in the cavity regi…
Levels and Potential Health Hazards of Chlorinated Pesticidesin Surface Water Samples of Charsadda Area of Pakistan Using SPME-GC-ECD Technique
2021
In the present study, we determined the levels of chlorinated pesticide residues in surface water samples collected from the Charsadda district (KPK, Pakistan). SPME-GC-ECD with COMBI PAL CTC autosampler was used for extraction and analysis of 20 organochlorine pesticides in the collected water samples. For maximum efficiency of the SPME procedure, several parameters were studied, including the extraction and desorption time of the fiber, solution pH, agitation of samples, and stirring speed, etc. This method showed good liner response, with R2 values in the range of 0.9887 to 0.9999 for all pesticides. This method also provided good percent recoveries at 1 µg L−1 (87.5 to 106.0%) and at 2 …
Free school fruit: can an extra piece of fruit every school day contribute to the prevention of future weight gain? A cluster randomized trial
2014
Background: Several school fruit programs are initiated with the aim to improve diet and thereby contribute to reduce the prevalence of overweight. To date, no published studies have demonstrated that school fruit schemes do prevent overweight.Objective: The aim of the present study was to assess if increased consumption of fruits and vegetables, due to free school fruit, have an impact on future weight status.Design: An intervention study including 10- to 12-year-old children from nine schools in two Norwegian counties (Hedmark and Telemark) participating in the Norwegian School Fruit Program for free during the school year 2001/2002 and children from 29 control schools. Follow-up studies …
Orientacja procesowa w zarządzaniu publicznym łańcuchem dostaw
2015
W artykule podjęto problematykę możliwości wdrożenia orientacji procesowej do zarządzania publicznym łańcuchem dostaw. Wskazano na znaczenie uwarunkowań polityczno-prawnych, wyznaczających system celów i tworzących ramy realizacji zadań publicznych. Pokazano, że istotne znaczenie ma identyfikacja procesów podstawowych i wspomagających oraz koordynacja styków w łańcuchu tworzenia wartości publicznej. Podkreślono wagę wyznaczania jednostek odpowiedzialnych za realizację procesu, zwłaszcza w kontekście mnogości podmiotów, w tym prywatnych, realizujących świadczenia publiczne.
Un compendio de Investigaciones en economia de la educacion
2012
Este artículo presenta los principales temas abordados por los economistas de la educación a lo largo de los últimos cincuenta años. Después de recordar brevemente los antecedentes de la disciplina, se describen las aportaciones teóricas y empíricas realizadas a raíz del desarrollo de la teoría del capital humano, que es el fundamento de la economía de la educación. Más allá de los trabajos que tratan de los efectos externos de la educación, el artículo repasa también las principales aportaciones efectuadas en el análisis de los sistemas de enseñanza y en la evaluación de las políticas educativas.
