Abstract: Se plantea una intervención en educación alimentaria y nutricional en nueve escuelas de la comuna de Pe alolén, con una escuela control. El objetivo es evaluar los cambios en el estado nutricional, conocimiento y consumo de alimentos de los ni os de prebá-sica y básica durante el primer a o de la intervención, comparados con el colegio control. Es un estudio cuasi-experimental, de seguimiento longitudinal en 1556 ni os de prekinder, kínder, primero y segundo básico (1225 ni os de las escuelas intervenidas y 331 de la escuela control) seguidos durante un a o escolar. Se realizaron actividades educativas con profesores y alumnos y la evaluación consistió en una medición de su estado nutricional en marzo-abril y octubre-noviembre del a o 2010; una medición de las colaciones en los ni os de prekinder y kínder, con una encuesta alimentaria a los de primero y segundo básico. Los resultados mostraron que no hubo cambio en el estado nutricional en el total de los ni os intervenidos, aumentando levemente el sobrepeso y obesidad en el colegio control. Sin embargo, al hacer el análisis por colegio, en siete de los nueve colegios intervenidos disminuyó la obesidad. En cuanto a consumo, un alto porcentaje de ni os de prebásica llevaban jugos y bebidas en las colaciones y en los ni os de básica se produjo un incremento significativo del consumo de frutas y lácteos durante el a o. En conocimiento, los ni os de primero y segundo básico tuvieron una buena comprensión en frutas y lácteos, no así para el pescado y legumbres. A pesar del corto período de intervención, este estudio permite se alar que cuando las intervenciones en alimentación y nutrición se realizan en forma estructurada y son evaluadas, pueden tener un impacto positivo en el cambio de hábitos alimentarios y en la disminución de la obesidad en preescolares y escolares de escuelas municipales. A food and nutrition education intervention was implemented in nine public schools in Pe alolen, Chile, with one control school. The objective was to determine the trend in obesity prevalence and in food knowledge and food consumption in preschool and school-age children followed longitudinally in the first year of intervention, compared with the control school. The sample included 1556pre-school, first and second grade (1225 children in experimental schools and 331 in the control school) followed during one school year. Nutrition education activities were performed with teachers and students, and the evaluation of nutritional status was carried out in two points, March-April and October-November 2010. There was also on

Abstract: a food and nutrition education intervention was implemented in nine public schools in pe?alolen, chile, with one control school. the objective was to determine the trend in obesity prevalence and in food knowledge and food consumption in preschool and school-age children followed longitudinally in the first year of intervention, compared with the control school. the sample included 1556pre-school, first and second grade (1225 children in experimental schools and 331 in the control school) followed during one school year. nutrition education activities were performed with teachers and students, and the evaluation of nutritional status was carried out in two points, march-april and october-november 2010. there was also one measurement of snack consumption in pre-school children and a food and nutrition survey in school age children at the beginning and at the end of the year. results showed that there was no change in overweight and obesity in the intervened school-age children, and a small increase in the control school. however, analyzing nutritional status by school, in seven of the nine experimental schools there was a decrease in obesity. a high percentage ofpreschool children carried soft drinks and juices to school. in school age children there was a significant increase in fruit and dairy consumption during the year. school age children had a good knowledge offruits and dairy food, but not offish and legumes. despite the short period of food and nutrition intervention, this study shows that interventions implemented in a structured way with an evaluation can have a positive impact on changing eating habits and improving the nutritional status of municipal preschool and school children.
Relative importance of different physical processes on upper crustal specific heat flow in the Eifel-Maas region, Central Europe and ramifications for the production of geothermal energy  [PDF]
Lydia Dijkshoorn, Christoph Clauser
Natural Science (NS) , 2013, DOI: 10.4236/ns.2013.52A039
Abstract:

We study the recent upper crustal heat flow variations caused by long-term physical processes such as paleoclimate, erosion, sedimentation and mantle plume upwelling. As specific heat flow is a common lower boundary condition in many models of heat en fluid flow in the Earth’s crust we quantify its long-term transient variation caused by paleoclimate, erosion or sedimentation, mantle plume upwelling and deep groundwater flow. The studied area extends between the Eifel mountains and the Maas river inCentral Europe. The total variation due to these processes in our study area amounts to tectonic events manifested in the studied area 20 mW/m2, about 30% of the present day specific heat flow in the region.

External Innovation Implementation Determinants and Performance Measurement: A Case Study from the Pharmaceutical Industry  [PDF]
Matthew Coates, Lydia Bals
Technology and Investment (TI) , 2013, DOI: 10.4236/ti.2013.42016
Abstract:

With an increasing amount of externally sourced innovations, a major success factor for innovation-dependent indus- tries such as the pharmaceutical industry is to successfully implement innovations from outside. Existing frameworks emphasize creating a strong climate for implementation by developing the learning capabilities of the organization, but there is still much to be learned about the process of implementing innovations that have been in-sourced by companies. As a research setting that is particularly innovation-driven and not well-studied yet, this study examines the key deter- minants for innovation implementation based on a case study in the pharmaceutical industry. The results of 25 expert interviews and a survey with 67 respondents led to the resulting framework and a corresponding performance meas- urement system. The results reveal the importance of supporting systems and show differences in perception of early and late Research & Development functions.

The Profile of Secondary Metabolites of Sponge Clathria reinwardtii Extract as a Result of Fe Accumulation in Spermonde Archipelago  [PDF]
Lydia Melawaty, Kristiana Pasau
Advances in Biological Chemistry (ABC) , 2015, DOI: 10.4236/abc.2015.57023
Abstract: Study on the effect of Fe metal concentrations in Spermonde Archipelago on secondary metabolites production from sponge was conducted. The percent of peak area and m/z from GC-MS at tR = 13.555 were affected by accumulated Fe in Chlathria reinwardtii, where at high Fe concentration a lower percent peak area was produced compared to Clathria rein-wardtii extract at low Fe concentration. Chromatogram CR-LL-DCM produced 2 peaks at tR = 21.401 and 25.174 which were not observed in CR-BC-DCM chromatogram. This indicated that Clathria reinwardtii in Lae-Lae island produced metabolite secondary compounds that were not produced by Clahtria reinwardtii in Barrang Caddi island. FT-IR analysis indicated that Clathria reinwardtii accumulating Fe with highest and lowest concentration produced strong peaks at wavenumber of about 3400 cm-1 for O-H and N-H stretches. O-H pliable and C-O stretch peaks at wavenumber of about 1200 cm-1 had changes from medium intensity at low Fe concentration (CR-BC-DCM) to weak at high Fe concentration (CR-LL-DCM).
The relationship of mineral and geochemical composition to artificial radionuclide partitioning inYenisei river sediments downstream frommining-and-chemical combine rosatom  [PDF]
Bondareva Lydia, Artamonova Svetlana
Natural Science (NS) , 2011, DOI: 10.4236/ns.2011.37073
Abstract: Discharges from the Mining-and-Chemical Com- bine (MCC) of Rosatom, downstream from Krasnoyarsk-26, near of the Krasnoyarsk resulted in radioactive contamination of sedi-ments of the River Yenisei. The concentration of artificial gammaemitting radionuclides (137Cs, 60Co, 152Eu, and 241Am) was determined to analyze the migration processes leading to the transport of these radionuclides. The concentration of artificial radionuclides in the surface layers of the studied area varied in wide ranges: 137Cs – 318 - 1800 Bq/kg, 60Co – 87 - 720 Bq/kg, 152Eu – 12 - 287 Bq/kg and 241Am – 6 - 76 Bq/kg. There was a sequence of migration of radionuclides investigated in the surface layer of sedi-ments that were collected in the near zone of influence of the MCC: 241Am ≈ 152Eu >60Co >137Cs. Radionuclide species have been found to be directly related to sediment structure and composition.
The Utilization of the National Qualifications Framework Level Descriptors as Criteria for Assessing Prior Experiential Learning to Access to Higher Learning Institutions of Namibia  [PDF]
Lydia Shaketange, Alex Kanyimba
Open Journal of Social Sciences (JSS) , 2017, DOI: 10.4236/jss.2017.510025
Abstract:
The assessment of experiential learning is the process of identification, articulation and legitimization of learning gained from years of work experience. The aim of this paper is to explore the utilization of level descriptors as criteria for assessing the prior experiential learning of candidates who aspire to access higher education. The recognition of the prior learning (RPL) concept has been embraced in education policies around the world as a process that assesses and recognises non-formal and informal learning attained by an individual, to determine the level of competency achieved. However, the implementation of the concept by higher education institutions remains insignificant. Some reasons cited relate to the method used to assess learning in admission tests, such as the recall of subject knowledge. It is argued in this paper that the alignment of individuals’ learning evidence with the National Qualifications Framework’s level descriptors is critical as an alternative route of assessment. The assessment method based on alignment of level descriptors allows for self-exploration and deeper reflection of own learning, giving insight not only into the self but also for the benefit of the host institution. Host institutions benefit from RPL, not only by choosing qualified candidates to enter their programmes, but also by having candidates who lived the experience and have understanding of the field of study. The alignment method is perceived to be a reflective strategy of assessing experiential learning and is born out of the transformative process which encourages deep learning and portrays the quality of potential candidates. Studies have shown no significant differences between the performances of students who accessed higher learning through Grade twelve certificates and those who accessed through RPL. Therefore, when an appropriate and robust method is adopted, RPL is feasible and beneficial to all involved.

Abstract: The University of Namibia (UNAM) has developed and approved a policy on the recognition of prior learning (RPL), but the implementation thereof is dormant. The purpose of this paper is to present potential challenges and opportunities that can influence the implementation of RPL at UNAM. The paper used a qualitative approach and the phenomenological design to solicit participants’ views, perceptions and experiences concerning RPL at UNAM. Semi-structured interview schedules were employed to collect data from 12 staff members of UNAM who were purposively chosen based on their positions that are key to providing information to answer the research questions. The findings reveal opportunities such as the availability of political will to implement RPL at the institution, the availability of expertise, capability in terms of technology and infrastructure, the availability of RPL policy, quality assurance and the assessment policy of the institution. Challenges identified are lack of ontological knowledge of what counts as RPL, how it is assessed and its validity and integrity. The data reveal high demands regarding training on issues of assessment and raising awareness of RPL at the institution. The paper recommends that the Ministry of Education, the Namibia Qualifications Authority and the National Council of Higher Learning spearhead a
Precios, inversión y economía política de la energía eléctrica
Benavides,Juan;
Revista de Ingeniería , 2007,
Abstract: this piece puts together several strands of conceptual themes that are central to the design of electricity market architectures. it starts by delineating the economic characteristics of electricity (whose wholesale markets are inherently incomplete and imperfectly competitive). the role and scope of frequent price adaptation as a welfare maximizing tool is also discussed, as well as the complementary nature of price adaptation and capacity expansion, which can be compactly expressed with the help of variational inequalities. finally, it points out some of the real-politik constraints that emerge in the process of reforming publicly-owned electricity systems and concludes with the need of using a transaction-cost approach in the reform design process.
