The banana is widely and intensively cultivated in the tropics. Traditional production employs a high input of industrial supplements, the excess of which contaminates the environment, altering existing edaphic populations and their functions. Some producers have incorporated other plant species in polycultures to reduce costs and achieve an alternative production without the high consumption of chemical supplements. With the aim of evaluating the effect of management system (monoculture vs. polyculture) and determining the edaphic factors that influence the richness and diversity of arbuscular mycorrhizal fungi (AMF), an edaphic component of great importance, 17 banana plantations in Colombia with high contents of edaphic phosphorous were sampled in two high production zones managed under a monoculture system and a zone of low production managed under a polyculture system. Between 11 and 18 species of AMF were found on average per plantation, both in intensive agricultural systems and in polyculture, where the diversity índices Simpson, Shannon and Margalef as well as the abundance and richness of AMF did not appear to be influenced by the cultivation system but instead by the dominant species in the communities; pH was the only factor that correlated positively with richness and the Margalef index; the monocultures were the least acidic and for this reason presented higher species richness. It is concluded that, in soils with high Phosphorus content, pH shows a direct relationship with species richness and the Margalef index, the composition of AMF species in the community exists in heterogeneous patches that are little influenced by cultivation management practice (mono or polyculture). Generalization in the development of specific bioinoculants based on mycorrhizae without considering local adaptations of the species is questioned. © 2016 Elsevier B.V.

Agroecology and Sustainable Food Systems | Year: 2017
The primary objective of this research was to thoroughly assess the social, economic, and environmental sustainability of 10 peasant farming production systems linked to Peasant Markets by means of economic, monetary and energy balances, and social analysis. Semistructured interview techniques were employed for data collection during the year 2011. Only three farming production systems—El Colegio, Villarrica, and Tuta—were comprehensively sustainable. In sum, peasant valuation of social and environmental benefits, agroecology, family labor, food self-sufficiency, short food supply chains, market linkage, collective cooperation, peasant pluriactivity, and food processing were all related to the strong sustainability of the peasant economy. © 2017 Taylor & Francis.

This paper reports a project that integrated grass-root communities of Alto Magdalena and Tequendama, Cundinamarca and academics from Uniminuto (Colombia) and Algoma (Canada) Universities. This partnership led to the participative design of a technological training program about regional development. This program combines three elements: world views, ancestral knowledge and the needs that the farming and peasant communities of Cundinamarca perceive as imperative. The authors were invited to join the initiative by leading a historical reflection on the conflicting views of technology as a source of community and environmental difficulties, and also as an opportunity to overcome the pressing challenges that rural communities face nowadays (i.e. young people migration, low productivity and environmental degradation). This dialogue between academics and community members dealt with technological initiatives, such as energy for lighting and cooking, grass-root initiatives for rural connectivity and social media, water & sanitation, and agricultural technologies. In addition, a debate took place that focus on the community memory about large scale institutional programs for technological development. The paper discusses the motivation, methodology, outcomes, and conclusions of this partnership. The discussion has a socio-technical perspective, linking concrete technological initiatives to a broader understanding of the economical, political, cultural and environmental factors that define successful humanitarian technology implementation. © 2016 IEEE.

At the state of the Vaupés, the Traditional Medicine (MT) has a fundamental roll between the native communities, being orally transmitted among generations, which could lead to loss of knowledges. It is pretended through a semi-structured survey done to teen agers, to determine their importance to the (MI). As a result it was obtained that a marked single polinguilism exists, but it is represented by minor ethnolinguistic groups, explaining a constant permeability of knowledge and traditions, however it is observed a clear appreciation of the MT and of the implicit processes, being related with the use of the native languages and the done inter-action with their community, family and school. It is the reason why community activities like to fish, wash clothing at the river and work in the farm are huge influenced activities for the MT appropriation, and been influenced by the integration capacity with their language elder people. © 2017 Boletín Latinoamericano y del Caribe de Plantas Medicinales y Aromáticas.

To understand the practices and the experimental formation of the psychopedagogy of abnormal childhood in Colombia, carried out in the San Jose Juvenile Correctional Facility and Work School, Colombia, between 1914 and 1947. Methods and materials: qualitative study, of a historical-hermeneutic approach, using documentary research, and file heuristics of document heritage and institutional historiography within the study period. Conclusions The emergence of a new special education regime (medical and psychopedagogical) established an important change in the model of punishing reformatory to pedagogical intervention, influenced by crossing scientific doctrines of the late nineteenth and early twentieth centuries, such as the rule of normal and pathological, the degeneration theory and eugenics, for perfecting a modern subject who can be useful to itself and to society. © 2009 University Association for Research in Fundamental Psychopathology.

Objective To compare the perceptions about HIV/AIDS of homosexual and bisexual Colombian males who live in the Colombian "Eje Cafetero" (Coffee Zone) and of those who migrated to Spain, in order to investigate whether those perceptions have an influence on the social vulnerability of the groups involved, which is determined by aspects such as inequalities that may emerge from ignorance about cultural and sexual diversity of the people who are undergoing a migratory process. Methods This research has a transnational character and was carried out by way of in-depth interviews of adult males living in the autonomous communities of Madrid, Valencia, Cataluña and Andalucía in Spain, and in the departments of Caldas, Quindío, Risaralda and Valle del Cauca in Colombia between 2011 and 2013. In total, 87 interviews were performed in both countries. Conclusion The relationship between migration and sexuality must be contemplated from a comprehensive viewpoint that enriches understanding both of the society of origin as well as of the welcoming country through a consideration of social and cultural aspects. Any health promotion and prevention program expecting to have an influence on social aspects must take into account people’s particularities in order to avoid generalizations and their exploitation, recognizing them and making them visible as individuals with full rights who express opinions, speak and participatevisible as whole right individuals, who express opinions, speakand participate. © 2016, Universidad Nacional de Colombia.

This document describes the architecture and technology of an IPTV network and, present the direct causes that generate considerable in the delay time of channel switching to user perception. Also some techniques that have been developed to mitigate the delay in the zapping are listed. This work propose developing an ARIMA time series model to model and predict the behaviour of the rating in the channels with more audience on an IPTV platform. The validation of the proposed model is performed from real data of the rating provided by UNE Telecommunications. The results show a low percentage of error in the prediction of the rating for one week and mitigation of channel zapping delay in 68% approximately.

Motion sickness or kinetosis is the result of the abnormal neural output originated by visual, proprioceptive and vestibular mismatch, which reverses once the dysfunctional sensory information becomes coherent. The space adaptation syndrome or space sickness relates to motion sickness; it is considered to be due to yaw, pith, and roll coordinates mismatch. Several behavioural and pharmacological measures have been proposed to control these vestibular-associated movement disorders with no success. Galvanic vestibular stimulation has the potential of up-regulating disturbed sensory-motor mismatch originated by kinetosis and space sickness by modulating the GABA-related ion channels neural transmission in the inner ear. It improves the signal-to-noise ratio of the afferent proprioceptive volleys, which would ultimately modulate the motor output restoring the disordered gait, balance and human locomotion due to kinetosis, as well as the spatial disorientation generated by gravity transition.

To improve the quality of people life and to reduce the risk of vulnerability of these, the engineering has some challenges. The engineering learning and engineering teaching should to create and to recreate them, that which is possible with the understanding and the approach to the reality or situation that the engineering students want to transform with students of other disciplines. An example of these initiatives is the The Center of Education for the Development (CED). In this center professors and students of all the academic programs converge which I lower the pedagogic focus of education for the development. They have to design and implement practical in social responsibility as Engineer's project to the Neighborhood with Ingenieros sin Fronteras. These projects are learning spaces where the students have the possibility in classroom and marginal communities to apply knowledge among other disciplines and to acquire new knowledge, abilities and vital social and talkative competitions for their professional exercise and interaction with the other ones.

In the present study we used the instrument developed by Davidson (2006) to measure logistics indicators in logistics management of two types of operations in two different disasters in Colombia. Key indicators in humanitarian logistics are used to compare performances of local aid organizations in the two operations. Results indicate a great difference between the organizations performance according to the type of disaster. In a forced-migration operation, indicators are lower than in a flooding operation; difficulties to reach the site due to actions of illegal armed groups hampered the access to the affected population. The key performance indicator framework can be used further to assess the performance of private and government organizations which carry out humanitarian operations in Colombia. © IFAC.
