ResumenLa presente investigación se propuso recoger información sobre el uso de las Tecnologías de la Información y la Comunicación (TIC) en la actividad docente universitaria, la percepción del profesorado sobre las TIC y la valoración de la infraestructura tecnológica disponible, desde una perspectiva comparativa entre universidades públicas y privadas. Para tal propósito se realizó una encuesta entre 147 profesores de instituciones del Eje Cafetero, Colombia. Se recurrió al análisis factorial, el análisis de correspondencias múltiples y pruebas de independencia. Se encontraron marcadas diferencias entre profesores de universidades públicas y privadas. Algunas diferencias con respecto al género, pero no se hallaron diferencias significativas con respecto a otras variables descriptivas del docente como la edad, la escolaridad o los años de experiencia docente. Pero aunque los indicadores favorecen a los docentes de instituciones privadas, también se evidencia un mayor nivel de estrés asociado al uso de las tecnologías entre ellos. Palabras clave: uso de las TIC; percepción sobre las TIC; universidades públicas y privadas; análisis factorial; análisis de correspondencias múltiples Comparative Study about Perception and use of ICT among Teachers of Public and Private Universities AbstractThe purpose of this research was to collect information about the use of Information and Communication Technologies (ICT) in university teaching, the perception of the teachers about the ICT and the assessment of the technological infrastructure available, from a comparative perspective between public and private universities. For this, a survey was carried out among 147 teachers from institutions of the Eje Cafetero, Colombia. Factor analysis, multiple correspondence analysis and independence tests were used. Marked differences were found between teachers of public and private universities, some differences with respect to gender, but no significant differences were found in relation to other descriptive variables of the teacher such as age, education level or years of teaching experience. But although the results are favorable to the teachers of private institutions, there is also evidence of a higher level of stress associated with the use of technologies among them.

In human-transformed landscapes, predators may feed on domesticated animals, and thus affect human well-being, creating negative perceptions and leading to conflict with people that can result in the persecution of the predator. We studied the factors that influence the perception of the Black-and-chestnut Eagle (Spizaetus isidori) in four rural Andean communities in Colombia and compiled historical and recent evidence on the persecution and other causes of mortality of this species in the country. We applied 267 questionnaires and conducted 16 interviews with local inhabitants, via visits to homes and schools in the surroundings of S. isidori nests. The perception of S. isidori by the inhabitants was largely negative and influenced by different socio-demographic factors such as gender, chicken (Gallus gallus) ownership, and chicken management. The records we obtained indicate that 47 eagles were shot, 16 were captured (three for illegal trafficking) and two were electrocuted on hightension wires. The persecution of S. isidori occurs as retaliation or as a preventative measure against chicken predation, and is a significant cause of mortality of this species in Colombia. Effective conservation planning for S. isidori in Colombia needs to go further than the protected areas system, and include a socioecological perspective in conservation practices applied at landscapes scales that are dominated by people. Education programs and socioecological research, along with participatory work in local communities are key to the conservation of S. isidori in breeding territories. This approach can also prevent conflict over food resources-G. gallus and other poultry-that are shared by humans and S. isidori in rural landscapes.

ResumenEl presente trabajo presenta los resultados de un estudio orientado a la obtención de indicadores de desempeño en un sistema de transporte público, desde tres enfoques, el analítico, el de simulación y el de accesibilidad urbana. Para ello se toma como caso de estudio el análisis de desempeño del sistema de transporte tipo Cable Aéreo de la ciudad de Manizales en Colombia. Se aplica el modelo teórico de redes abiertas de Jackson, desde la perspectiva de la simulación discreta. Los modelos de oferta se abordan a partir del análisis de accesibilidad urbana, para lo cual se toman los datos obtenidos por el Plan de Movilidad de la ciudad, en el cual se usaron los programas TransCad y Surfer. A partir de las mediciones de desempeño mediante los enfoques analítico y simulado, se obtiene una baja tasa de uso del sistema de transporte, lo cual ratifica claramente los resultados obtenidos por los análisis de accesibilidad urbana. Palabras clave: transporte público; simulación discreta; redes abiertas de Jackson; cable aéreo; accesibilidad urbana Measuring of the Performance of the Overhead Cable Transport System of the City of Manizales in Colombia, using Three Approaches: Analytical, Simulated and Urban Accessibility AbstractThis paper presents the results of a study aimed to obtain performance indicators in a public transport system, from three approaches, analytical, simulation and urban accessibility. For the study the Air transport Cable type of the city of Manizales in Colombia is taken as a case of study. The theoretical model of open networks of Jackson was applied, from the perspective of discrete simulation. The supply models are addressed through the analysis of urban accessibility, for which the data obtained by the Mobility Plan of the city, using the TransCad and Surfer software. The results show that for performance measures, a low rate of use of the transport system is obtained, which clearly confirms the results obtained by the analysis of urban accessibility.

Tomato is considered a fruit with a high food demand across the world due to its high antioxidant capacity. Lycopene content in tomato has been widely studied, particularly in cherry-type tomatoes which are considered a high source of lycopene for humans. The aim of this study was to analyze the differences in terms of concentration and variation of diverse physicochemical parameters of quality (acidity, vitamin C, pH, °Brix, color coordinates L*, a* and b*) and, antioxidants like β-carotene and lycopene in 11 accessions of cherry-type tomatoes, considering the advantages of antioxidants for human health. Multicriteria analysis and other tests showed substantial differences among the accessions. IAC401 was associated with the best physicochemical characteristics of a promissory cherry-type tomato for cultivation due to its association with functional food, followed by IAC426R and IAC1624. This study allowed an innovative association of physicochemical characteristics and antioxidant contents of cherry-type tomatoes through multicriteria analyses which enable the analysis, elimination, and proposal of promising accessions for their use in future crops which will promote the best intrinsic features of tomato to be used in the studied region. In this case accessions with the highest scores offer not only optimum amounts of antioxidants and highest levels of organic acids and sugars.
