Este artículo surgió de la investigación cualitativa "El abordaje de la educación sexual en las familias de los estudiantes de las instituciones educativas de básica y media oficiales del municipio de Armenia, Quindío, y su influencia en la dinámica familiar", financiado por la Vicerrectoría de Investigaciones de la Universidad del Quindío, en donde se analizaron las variaciones de las funciones de la sexualidad de los niños, niñas y adolescentes (NNA), dentro de la dinámica familiar. Para la recolección de información se realizaron entrevistas a los diferentes actores de las instituciones educativas y a las familias de los estudiantes. Así mismo se consolidaron categorías inductivas que demostraron que el abordaje de la educación sexual en las familias se circunscribe al control de la natalidad, a las infecciones de transmisión sexual (ITS) y al deseo de tener una pareja estable; además, se reveló un gran temor frente al tema de la sexualidad por la deficiente formación y un inadecuado acompañamiento de la familia de origen. Las características de los entrevistados del núcleo familiar fueron: un promedio de edad de 40 años, estudios secundarios, con procedencia en su mayoría de los departamentos de Caldas, Valle del Cauca y Putumayo, viven hace 4 años en la ciudad, son empleados y poseen una tipología familiar reconstituida y monoparental. Las variaciones en la dinámica familiar son, en su mayoría, establecimiento de normas y reglas al interior del hogar, compartidas o consensuadas, utilización del diálogo para la solución de problemas y vínculos familiares fortalecidos a través de los espacios compartidos durante el tiempo libre, las expresiones de afecto y el apoyo familiar.

This paper evaluates the UK's Investors in People (IiP) policy initiative through an analysis of adoption and retention rates during its first 11 years of life. Established in 1991, the IiP Standard publicly credits organisations that "invest in their people" through training, development and worker involvement in decision making. Over time it has become one of the headline government policies and licenses to use it are being sold internationally. Our take on the accomplishments of IiP as a policy is to characterise involvement and life expectancy within the initiative. To this end we fit a duration model of participation in Investors in People. Once committed to the Standard, firms can exit to either becoming fully recognised Investors in People or else they can disengage from the programme without reaching full accreditation. We are therefore in a position of studying adoption and retention within a competing risk framework where we can assess the impact of organisational characteristics and the length of pre-recognition spells on success and failure rates. In accordance with the few previous findings, we find that large and public sector organisations present higher success rates. New findings we obtain include a strong interaction between employment changes and IiP accreditation and the fact that the Standard has become significantly easier to obtain over time. Hazard rates for later cohorts are three times as high as for those committed in 1991. Finally, we also present the first attempt to gain insight into the process of disengaging from the standard or ceasing participation.

The use of treated wastewater in agriculture is a measure of water management that provides significant economic, social and environmental issues and helps to reduce the water deficit in Andalusia. The aim of the "Recommendations Manual"is available to technicians and farmers an update and summary on the main aspects of reuse in agriculture, so they can manage it efficiently and safely. We have considered the legislative aspects governing its use, quality criteria, management of fertilization, irrigation management, maintenance of facilities and irrigation systems and sanitary recommendations. ; El uso de las aguas residuales depuradas en la agricultura es una medida de gestión hidrológica que aporta importantes beneficios económicos, sociales y medioambientales y que contribuye a reducir el déficit hídrico en Andalucía. El objetivo de estas "Recomendaciones de uso" es poner a disposición de técnicos y productores agrícolas una información actualizada y resumida sobre los principales aspectos de la reutilización en la agricultura, para que puedan gestionarla de forma eficiente y segura. Se han considerado los aspectos legislativos que regulan su uso, criterios de calidad, gestión de la fertilización, manejo del riego, mantenimiento de las instalaciones y los sistemas de riego y recomendaciones higiénico-sanitarias.

This paper presents a multiscale integrated analysis comparing changes in the energy metabolic pattern of China and the European Union between 2000 and 2016. The MuSIASEM method is used to explore and illustrate the entanglement over different factors, across dimensions and levels of analysis. Demographic factors observed at the level of the whole are linked to changes in the economic structure, the pattern of energy uses and the level of outsourcing (imports). When analyzing these issues for the selected case studies we found that: (i) due to their lower dependency ratio and higher workloads China presents now about 1260 h in paid work per capita, while the EU presents just 720; (ii) economic structure in China evolved rapidly moving almost 300 h per capita per year from agriculture to service, construction and industrial sectors, while it remained quite stable in the EU; (iii) the metabolic pattern of China changed dramatically by expanding its capital goods in all sectors (almost 4 times in agriculture and more than doubling in industry and services) while the EU just increased them around 10%. The quick industrialization of China (going from 20 to 60 MJ/h in paid work sector) required an extraordinary investment in the construction sector, which arrived to allocate almost 3 times more workforce and 5 times more cement per capita than the EU (already industrialized). The simultaneous reading of all these changes confirms known trends and identifies a few challenges. The apparent decoupling of economic growth from resource consumption in the EU economy is due to the outsourcing of industrial production (identified and quantified at the level of subsectors). The trajectory of economic development of China, still in the phase of industrialization, spells troubles in terms of future consumption of natural resources and pollution. The metabolic perspective used in the comparison enables to identify policy-relevant factors determining both temporary comparative advantages and dangerous locks-in. On the ...

This paper has been presented at : 9th International Conference on Pattern Recognition Systems (ICPRS 2018) ; Pedestrian detection and tracking have seen a major progress in the last two decades. Nevertheless there are always appli-cation areas which either require further improvement or that have not been sufficiently explored or where production level performance (accuracy and computing efficiency) has not been demonstrated. One such area is that of pedestrian monitoring and counting in metropolitan railways platforms. In this paper we first present a new partly annotated dataset of a full-size laboratory observation of people boarding and alighting from a public transport vehicle. We then present baseline results for automatic detection of such passengers, based on computer vi-sion, that could open the way to compute variables of interest to traffic engineers and vehicle designers such as counts and flows and how they are related to vehicle and platform layout. ; The authors gratefully acknowledge the Chilean National Science and Technology Council (Conicyt) for its funding under grants CONICYT-Fondecyt Regular nos. 1140209 ("OBSERVE") , 1120219, and 1080381 .

Since polyol is one of the major components in polyurethane foam synthesis, introducing renewably sourced polyols in the foam formulation leads to materials with high renewable carbon content. A series of flexible polyurethane foams with variations in polyol composition were synthesized with castor oil based Lupranol Balance ® 50 polyether polyol and corn based polytrimethylene ether glycol mixtures. Water was used as the unique and eco-friendly blowing agent. The effect of the relative amount of each polyol on the structure and properties was analyzed by optical microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis, tensile and compressive tests, dynamic mechanical analysis and atomic force microscopy. The average molecular weight and hydroxyl number of the polyol components showed to influence the foaming reaction and hence the structure and properties of the polyurethane foam. The newly developed peak force quantitative nano-mechanics technique was used to map the elastic modulus values of foam cell struts and it seemed to be adequate to assess the purity of the different phases. ; Authors thank financial support from University of the Basque Country (PIFUPV047/2011), Basque Government (IT776-13 and S-PE13UN091), Spanish Ministry of Economy and Competitiveness (MINECO) (IPT-2012-0728-420000) and European Union (PIRSES-2012-318996).
