Plataforma Tecnológica Colaborativa Comunidad de Negocios San Antonio, Chile, red de aprovisionamiento local: OpenSupply

El proyecto que se quiere plantear es la creación de una Plataforma electrónica a través de la cual se pretende agrupar a los diferentes proveedores que intervienen en la cadena de abastecimiento de la comunidad logística de San Antonio, abriendo la posibilidad de participación de empresas grandes y pequeñas y más aun promoviendo la creación de las mismas por parte de los ciudadanos de la región, de esta manera, se eliminan las brechas asimétricas existentes entre la oferta y la demanda permitiendo que las empresas medianas y grandes accedan a ofertas y transacciones con empresas proveedoras medianas y pequeñas. Dicho proyecto, tiene como objetivo general el consolidar los procesos de abastecimiento implementados por las empresas a través de la organización y estandarización de los mismos mediante el uso del portal, planteado en el presente proyecto, como apoyo tecnológico. Existen dos conceptos básicos a analizar de manera teórica dentro del proyecto, el primero de ellos es el de clúster logístico-portuario, lo cuales son reconocidos como instrumentos importantes para el progreso del desarrollo industrial, innovación, competitividad y crecimiento, tomando como ejemplos a los puertos de Valencia y Long Beach en la ciudad de Los Ángeles. El segundo concepto es el de E-Procurement, el cual se desarrolla siguiendo los pasos básicos de una cadena de abastecimiento tradicional, sin embargo, lo que genera un cambio real dentro de los procesos es el hecho que los procesos de cotización y seguimiento de proveedores se van a llevar a cabo a través de una plataforma electrónica con base a las evaluaciones que se llevan a cabo por parte de las empresas demandantes de los productos o servicios ofrecidos por las compañías proveedoras. (Renko, 2011) De la misma manera, se tomaran varios proyectos de e-procurement desarrollados a nivel mundial como base comparativa y de apoyo para el presente proyecto tales como: HYDRA: Es un sistema que tiene su soporte en la web, el cual es orientado “en el medio” lo cual lo hace un sistema con una arquitectura híbrida, que posee tanto un diseño en capas como una estructura comprensiva para desarrollar integración de negocios, colaboración y monitoreo en la gestión de la cadena de suministro (Renko, 2011) IPT: BidNet ha proporcionado servicios de oferta de información a miles de proveedores y compradores de bienes en el ámbito gubernamental por más de 25 años. (Bidnet, 2013) E-BUYPLACE: E-buyplace.com es el 1° especialista en SupplierRelationship Management que ha desarrollado un original y singular SRM 100% a través de Internet. (e-buyplace, 2013) RosettaNet: La iniciativa RosettaNet anima a optimizar los procesos de la cadena de suministro mediante el establecimiento, implementación y promoción de estándares abiertos en el mercado e-Business (AQS, Advance Quality Solutions, 2002)

Factores asociados a deficiencia de zinc en niños colombianos entre 1 y 4 años de edad

Introducción: Las deficiencias de micronutrientes continúan siendo un problema de salud pública en la población infantil, dentro de las ellas se ha encontrado a la deficiencia de zinc causa importante de morbi-mortalidad en los países en desarrollo, la nutrición adecuada de zinc es esencial para un crecimiento adecuado, inmunocompetencia y desarrollo neuroconductual; se dispone de información insuficiente sobre el estado de zinc en la población preescolar lo cual dificulta la expansión de las intervenciones para el control de su deficiencia. Colombia presenta una deficiencia de este micronutriente, considerándose a nivel mundial como un problema de salud pública moderado a severo. Una evaluación sobre la prevalencia y factores determinantes asociados puede proporcionar datos sobre el riesgo de deficiencia de zinc en una población, considerando factores demográficos, sociales y nutricionales que podrían predisponer a la población preescolar colombiana a sufrir este déficit. Metodología: Estudio observacional de corte transversal que incluyó 4275 niños entre 1 y 4 años, utilizando datos de la Encuesta Nacional de Situación Nutricional (ENSIN-2010). Se realizaron análisis bivariados y multivariados para determinar factores asociados positiva y negativamente con deficiencia de zinc. Resultados: El 49,1% de los niños encuestados cursaban con deficiencia de zinc. Los factores de riesgo asociados a deficiencia de zinc encontrados fueron menor edad, peso y talla bajos, vivir en región Atlántica, región Central, Territorios Nacionales, vivienda en área de población dispersa, pertenencia a etnia afrocolombiana, pertenencia a etnia indígena, estar afiliado a régimen subsidiado, no estar afiliado a ningún régimen de salud, madre sin educación, no asistencia a programa de alimentación dirigido y el grado severo de inseguridad Conclusiones: El déficit de zinc en los niños entre 1 y 4 años de edad es multifactorial, siendo un reflejo probable de la situación de inequidad de la población colombiana, en especial, la más pobre y vulnerable. Palabras clave: Zinc, Deficiencia de zinc, factores asociados, niños entre 1 y 4 años, Colombia

Estudio de caso. “el papel de los refugiados en la implementación de la política de libre circulación de la cedeao: visto desde el flujo de Liberia a Ghana”

Este estudio de caso tiene como objetivo determinar las implicaciones del flujo de población refugiada en la implementación de la política de libre circulación de la CEDEAO; tomando como referente el flujo desde Liberia hacia Ghana generado por la Guerra Civil. Esta investigación defiende que las implicaciones pueden estar relacionadas a las dinámicas que se asocian al movimiento de personas, las cuales pueden ser negativas o positivas, razón por la cual los Estados pueden reaccionar endureciendo las políticas migratorias, la obtención de permisos laborales y de residencia, y el cierre de fronteras o la expulsión de refugiados; con el fin de evitar consecuencias a nivel político, económico o en materia de seguridad. Para comprobar lo anterior se va a realizará un análisis de texto, sobre posiciones nacionales y políticas comunitarias, así como una revisión de estudios y estadísticas relacionados con el tema.

Propiedades psicométricas de la versión al español del cuestionario “Barriers to Being Active Quiz”, entre estudiantes universitarios de Colombia

Objetivo: El cuestionario Barriers to Being Active Quiz (BBAQ), indaga las barreras para ser físicamente activo. El cuestionario fue traducido al español por el mismo equipo que desarrolló la versión inglésa original, pero carece de estudios de validez en la versión española. El objetivo de esta investigación fue evaluar las propiedades psicométricas del BBAQ (en la versión completa de 21 ítems), centrándose en la fiabilidad y validez. Material y métodos: Un total de 2.634 (1.462 mujeres y 1.172 varones; 18-30 años de edad) estudiantes universitarios completaron el cuestionario BBAQ-21. El alfa de Crombach se estimó como indicador de consistencia interna. El coeficiente de correlación intra-clase (CCI) y el grado de acuerdo se calcularon para evaluar la estabilidad temporal con un periodo de 7 días entre ambas administraciones como estimadores de la reproducibilidad. Se aplicó un análisis factorial exploratorio (AFE) y confirmatorio (AFC) para analizar la validez del BBAQ-21 ítems. Resultados: El BBAQ-21 mostró valores de un alfa de Cronbach entre 0,812 y 0,844 y un CCI entre el 0,46 y 0,87. El porcentaje de acuerdo por todos los conceptos individuales varió de 45 a 80%. El AFE determinó cuatro factores que explicaron el 52,90% de la varianza y el AFC mostró moderadas cargas factoriales. Conclusiones: Los resultados obtenidos en este cuestionario avalan la utilización de este instrumento con este tipo de muestra, desde el punto de vista de la fiabilidad y validez. El BBAQ-21 está disponible para evaluar las barreras para la actividad física en América Latina.

Women, Portuguese culture and Diaspora : Women from Goa in New Zealand and cultural adaptation

New Zealand is a nation of Migrants. Immigrants have played a significant role in the country’s economic growth and cultural development. With a population of four million people, New Zealand’s population is becoming increasingly culturally diverse. Almost one in five New Zealanders were born overseas, rising to one in three in its largest city, Auckland. Asians are the fastest growing ethnic group, increasing by around 140% since 1996. Indians account for 1.2% of the population (Statistics New Zealand, 2002). The Goan community in New Zealand is relatively small and its size is not formally recorded, however, anecdotally it appears to have grown to over 200 families in the Auckland area, with most arriving after 1996. For women who migrate, loneliness and isolation have been identified as the most ‘glaring’ experience and this is intensified by the loss of extended family networks when they migrate to a country where nuclear families are the norm (Leckie, 1995). The creation of new networks and maintenance of prior networks in new ways is crucial to the successful settlement and integration into a new country. This paper reports on how Goan, Indian women in Auckland, New Zealand used specific strategies to manage the adjustment to living in a new country. The findings reveal that participants used a variety of skills to settle in New Zealand such as cultivating a “can do” attitude, obtaining support and learning. These skills enabled them to move beyond their own culture and begin to take active part in New Zealand culture. However, this process was not immediate and the participants passed through a number of stages along a continuum of settlement and integration. These stages will be discussed below and situated within a body of literature.

Women on March in Goa : the gender transition in Higher Education after the Statehood

This paper attempts to address the interesting phenomenon of dominance of women in higher educational sector of Goa-a remarkable postcolonial event which occurred after Goa attained statehood in 1987. The Indian state of Goa has been experiencing a rapid socio-economic and cultural transformation. At present it enjoys many of the highest human development indicators in India, matching some of the developed countries. Its’ projected population at present is 1.45 million (Indian decennial census 2001 reported 1.348 million). When the Portuguese rule ended, the literacy was just 31 % whereas it stood at 82 % in 2001. Goa is a highly urbanized state in India. In 1960 there were just five towns and 15 % urban population. In 2001 the figures were, 44 towns and 50 % urban population. On economic front Goa has made tremendous progress mainly on account of the growth of mining, tourism and the service sector. Tourist arrivals in Goa have exceeded the state’s population from 2001. The Gross state domestic product (GSDP) at current prices in 2003-04 was Indian Rupees (Rs.) 96570 million, up from Rs. 3930 million when Goa became a full-fledged state. The banks are flush with funds indicating a booming economy. Goa has lowest birth and death rates and a life expectancy of 68 years for the males and 72 for females. The sex ratio however has shown a declining trend since 1960, from 1066 to 960 in 2001 (Table 1).The sex ratio for 0-6 years age group was 933. On this background we intend to examine the changing pattern of female education in Goa.

Museum of the City of São Paulo: A new paradigm of City Museums in the Era of Megalopolises

The City is a tomography of the present, indicating to the future, strata of past times. Nowadays city growth averages one million people every week; while back in 1950 there were eighty six cities with more than one million inhabitants, today they are four hundred all over the world. However the most significant effect of the urban process is, doubtless, the explosion of megacities. It took one century for the urban population – around three point four billion inhabitants – to surpass the number of people in the country, but United Nations projections indicate that by 2025, urban population will reach 61% of the total. Creating a new city museum in São Paulo requires that, in a first analysis, one should consider as geographic area of study some fifteen hundred square kilometres corresponding to the patrimonial intervention area. That is the area of the Municipality, politically divided into ninety six districts where eleven million people live, while approximately twenty million people live in the metropolitan area

Fitness costs of dispersal in red foxes (Vulpes vulpes)

The costs of dispersal are an important factor promoting natal philopatry, thereby encouraging the formation of social groups. The red fox, Vulpes vulpes, exhibits a highly flexible social system and one that is thought to represent a possible stage in the evolution of more complex patterns of group-living. Although the potential benefits accruing to philopatric offspring have previously been studied in this species, the potential costs of dispersal have received less attention. We contrasted survival rates, nutritional status, injuries and reproductive output of dispersing and non-dispersing male and female foxes in an urban population to assess the relative costs of dispersal versus natal philopatry. Mortality rates were not significantly higher for dispersing foxes, either in the short- or long-term. There was no evidence of increased nutritional stress in dispersing individuals. Dispersing individuals did, however, exhibit greater levels of wounding, although this did not appear to affect survival. Dispersing females were more likely to miss a breeding opportunity early in their reproductive lifespan. In contrast, both dispersing and non-dispersing males were unlikely to breed in their first year. We conclude that the major fitness component in females affected by dispersing is age at first reproduction.

Commentary on 'Prebiotics, immune function, infection and inflammation: a review of the evidence'

There is a growing awareness that the gut microbiota and an appropriately functioning immune system play an important role in maintaining human health. Recent population statistics have highlighted some worrying trends, specifically that there is a growing burden of immunological disease in Western populations, that Western populations are ageing, and that obesity, with its strong inflammatory component, is reaching epidemic proportions.

Wall materials and techniques available for low cost housing in Khartoum from a sustainability point of view

Khartoum like many cities in least developing countries (LDCs) still witnesses huge influx of people. Accommodation of the new comers leads to encroachment on the cultivation land leads to sprawl expansion of Greater Khartoum. The city expanded in diameter from 16.8 km in 1955 to 802.5 km in 1998. Most of this horizontal expansion was residential. In 2008 Khartoum accommodated 29% of the urban population of Sudan. Today Khartoum is considered as one of 43 major cities in Africa that accommodates more than 1 million inhabitants. Most of new comers live in the outskirts of the city e.g. Dar El-Salam and Mayo neighbourhoods. The majority of those new comers built their houses especially the walls from mud, wood, straw and sacks. Selection of building materials usually depends on its price regardless of the environmental impact, quality, thermal performance and life of the material. Most of the time, this results in increasing the cost with variables of impacts over the environment during the life of the building. Therefore, consideration of the environmental impacts, social impacts and economic impacts is crucial in the selection of any building material. Decreasing such impacts could lead to more sustainable housing. Comparing the sustainability of the available wall building materials for low cost housing in Khartoum is carried out through the life cycle assessment (LCA) technique. The purpose of this paper is to compare the most available local building materials for walls for the urban poor of Khartoum from a sustainability point of view by going through the manufacturing of the materials, the use of these materials and then the disposal of the materials after their life comes to an end. Findings reveal that traditional red bricks couldn’t be considered as a sustainable wall building material that will draw the future of the low cost housing in Greater Khartoum. On the other hand, results of the comparison lead to draw attention to the wide range of the soil techniques and to its potentials to be a promising sustainable wall material for urban low cost housing in Khartoum.

Dying young: a palaeopathological analysis of child health in Roman Britain

Children represent the most vulnerable members of society, and as such provide valuable insight into past lifeways. Adverse environmental conditions translate more readily into the osteological record of children, making them primary evidence for the investigation of ill-health in the past. To date, most information on growing up in Roman Britain has been based on the Classical literature, or discussed in palaeopathological studies with a regional focus, e.g. Dorset or Durnovaria. Thus, the lifestyles and everyday realities of children throughout Britannia remained largely unknown. This study sets out to fill this gap by providing the first large scale analysis of Romano-British children from town and country. The palaeopathological analysis of 1643 non-adult (0-17 years) skeletons, compiled from the literature (N=690) and primary osteological analysis (N=953), from 27 urban and rural settlements has highlighted diverse patterns in non-adult mortality and morbidity. The distribution of ages-at-death suggest that older children and adolescents migrated from country to town, possibly for commencing their working lives. True prevalence rates suggest that caries (1.8%) and enamel hypoplasia (11.4%) were more common in children from major urban towns, whereas children in the countryside displayed higher frequencies of scurvy (6.9%), cribra orbitalia (27.7%), porotic hyperostosis (6.2%) and endocranial lesions (10.9%). Social inequality in late Roman Britain may have been the driving force behind these urban-rural dichotomies. The results may point to exploitation of the peasantry on the one hand, and higher status of the urban population as a more ‘Romanised’ group on the other. Comparison with Iron Age and post-medieval non-adults also demonstrated a decline in health in the Roman period, with some levels of ill-health, particularly in the rural children, similar to those from post-medieval London. This research provides the most comprehensive study of non-adult morbidity and mortality in Roman Britain to date. It has provided new insights into Romano-British lifeways and presents suggestions for further work.

Agricultural innovations at a Late Iron Age oppidum: archaeobotanical evidence for flax, food and fodder from Calleva Atrebatum, UK

The development of oppida in the late first millennium BC across north-western Europe represents a major change in settlement form and social organisation. The construction of extensive earthwork systems, the presence of nucleated settlement areas, long-distance trade links and the development of hierarchical societies have been evidenced. These imply that changes in the style and organisation of agriculture would have been required to support these proto-urban population centres. Hypotheses of the subsistence bases of these settlements, ranging from a reliance on surplus arable production from local rural settlements, to an emphasis on pastoral activities, are here reviewed and grounded against a wider understanding of the expansion of agriculture in the Late Iron Age. These agricultural models have not been previously evaluated. This paper presents archaeobotanical data from six well fills from large-scale excavations at Late Iron Age and Early Roman Silchester, a Late Iron Age territorial oppidum and subsequent Roman civitas capital located in central-southern Britain. This is the first large-scale study of waterlogged plant macrofossils from within a settlement area of an oppidum. Waterlogged plant macrofossils were studied from a series of wells within the settlement. An assessment of taphonomy, considering stratigraphic and contextual information, is reported, followed by an analysis of the diverse assemblages of the plant remains through univariate analysis. Key results evidence animal stabling, flax cultivation, hay meadow management and the use of heathland resources. The staple crops cultivated and consumed at Late Iron Age and Early Roman Silchester are consistent with those cultivated in the wider region, whilst a range of imported fruits and flavourings were also present. The adoption of new oil crops and new grassland management shows that agricultural innovations were associated with foddering for animals rather than providing food for the proto-urban population. The evidence from Silchester is compared with other archaeobotanical datasets from oppida in Europe in order to identify key trends in agricultural change.

Understanding student expectations in developing environmental science courses

Developing relevant and innovative University courses is a complex and often difficult task. This is particularly true when developing environmental science courses as the banner of environmental science has the potential to include an extremely vast array of subject material and course content. Added to this is the diversity of students entering these courses, and their associated course expectations and aspirations. A third component that cannot be ignored when developing courses includes employer demands and expectations of graduates at course completion. As tertiary educators we therefore have the challenge of developing innovative environmental science courses that are academically challenging, but meet the expectations of students, staff and potential future employers. To ensure that we meet this challenge it is vital that we determine the expectations of all relevant parties (students, staff, and potential employers) and develop our courses accordingly.  Here we report on the 'student expectations' component of this. To determine student expectations we conducted a survey of all commencing first year environmental science students. The survey asked students to provide information on drivers for course selection, preferred learning styles, the importance of different approaches to teaching, subject interest areas and employment aspirations. Our results found that environmental science students have a preference for fieldwork and hands-on experience and are very supportive of teaching that combines different teaching methods. On-line teaching was not supported by commencing environmental science students. Commencing students showed a very strong interest in key subject areas of environmental science such as Wildlife, animal conservation, national and marine parks, conservation and marine Wildlife; however, some of the critical areas of environmental science such as population statistics, social sciences and chemistry did not attract the same level of interest. Most commencing students had some idea on where they would like to gain employment on course completion. Knowledge relating to student expectations is Vital, particularly when designing courses, developing specific unit content and undertaking marketing and course information sessions. With this knowledge we can be confident that students enrolling in environmental science will, to a large extent, have their expectations met.

Gender, age, and educational-attainment differences in Australian adults' participation in vigorous sporting and fitness activities

Background: Participation in regular vigorous physical activity could confer health benefits additional to those derived from moderate-intensity physical activities that are currently the focus of public health strategies.
Methods: Sociodemographic differences in reported participation in vigorous sporting and fitness activities over the past 2 weeks were examined using cross-sectional data from an Australian urban population sample.
Results: Participation at least once in any form of vigorous physical activity and regular participation (six or more sessions) both decreased across successive age groups and from high to low levels of education. The most frequently reported types of vigorous physical activity were cycling (13.3%), jogging (10.1%), swimming (8.4%) for men; and, swimming (8.9%), cycling (8.8%) and aerobics (8.6%) for women.
Conclusion: Rates of regular participation in vigorous activities were low. Interventions might focus on ways to encourage younger adults to engage more regularly in these activities and to maintain participation through the lifespan.
