Small-World Networks of corruption

Abstract: Collective behavior forms and spreads through social contact. This thesis introduces a framework for understanding how the structure of social ties may impact the evolution of bribery. We represent relationships as highly clustered networks with small characteristic path lengths (i.e., small-world models having “local” and “long-range” contacts). Based on a principal-agent-client formulation, our model focuses on the effects of clustering on an equilibrium of persistent bribery. Collective outcomes depend on decision-making mechanisms that rely on sensitivity functions, which capture the level of influence between local contacts. Moreover, we represent the evolution of the network as a system of differential equations and identify its region of parameters for which the equilibrium of persistent bribery is stable. Our results show that an increase in clustering tends to decrease the levels of bribery. A more sensitive response to the behavior of neighbors, on the other hand, tends to increase bribery, but only up to a certain point. Beyond this threshold, the expected level of bribery remains constant, despite variations in the structural properties of the network.

IoT Monitoring of Water Consumption for Irrigation Systems Using SEMMA Methodology

Abstract: The efficient use of water is an issue that has captured the attention of scientists, technicians, and the community at large. The sustainability of water resources has been threatened by the current imbalance between water supply and demand. Intelligent consumption of water would contribute to the balance and reduce the waste in applications such as the agriculture. This paper shows the design of a water consumption monitoring system based on the Internet of Things (IoT). With the implementation of this system could be known in real time the consumption of water in a crop. In addition, the user of the system may take corrective actions that optimize their water consumption; this is achieved by applying the SEMMA methodology to evaluate the data obtained by the system using two cluster algorithms, Simple K-means and GenClus++. With the application of SEMMA it was possible to determine periods of water consumption that were considered as waste in the irrigation of crops, applying data analysis with both algorithms.

Aportes de los métodos Bobath y Rood en el tratamiento fisioterapéutico del paciente con lesión de neurona motora superior

Abstract: El presente articulo describe los resultados de la aplicacion de los metodos de Bobath y Rood en la modulacion del tono en pacientes con lesion de neurona motora superior (LNMS). El primer metodo utiliza las tecnicas de inhibicion y facilitacion y el segundo emplea los mismos principios pero ademas tiene en cuenta la activacion del musculo esqueletico. Para el desarrollo del estudio se empleo la metodologia estudio de caso en el cual se incluyeron tres de las principales alteraciones de neurona motora superior como son: la Enfermedad Cerebro Vascular (ECV), la Paralisis Cerebral (P.C) y el Trauma Raquimedular (TRM), las tecnicas empleadas buscan la modulacion del tono espastico y se pretendio determinar cual es mas efectivo. Para recopilar la informacion se realizo evaluacion neurologica pre y pos intervencion, obteniendo que depende del tipo de lesion y de la edad, la efectividad entre un metodo y otro.

Laboratorio Galea: Un espacio en transformación e innovación para la enseñanza-aprendizaje

Abstract: El desarrollo de competencias y el fortalecimiento del aprendizaje en los individuos, son objetivos esenciales para la academia. Por esto, diversas instituciones han implementado nuevas metodologias de ensenanza-aprendizaje basadas en gamificacion, con el fin de alcanzar sus objetivos de educar profesionales integrales, aspectos que son relevantes para instituciones de educacion superior como la Universidad Industrial de Santander, quien las ha adoptado en el Laboratorio Galea, espacio creado para el desarrollo y aplicacion de las nuevas metodologias de ensenanza-aprendizaje. De esta forma, este documento aborda el proceso de elaboracion de un plan estrategico, para renovar aspectos del laboratorio, a la vez que se disenaron y aplicaron de diversas ludicas a la comunidad estudiantil. Para lograr esto, se implemento una encuesta y se aplico a diversos actores de la comunidad UIS, proceso apoyado por otras universidades. Los resultados obtenidos dieron una nocion mas clara de lo que significa el Laboratorio para la comunidad academica, datos que permitieron renovar la mision, vision y valores del laboratorio, asi como el diseno y ejecucion de nuevas actividades de gamificacion, que potencian las competencias y el aprendizaje de los estudiantes.

Estado de conservación y distribución del pez de agua dulce Capitán de la Sabana Eremophilus mutisii en Cundinamarca, Colombia

Abstract: Eremophilus mutisii (Humboldt, 1805), is an endemic fish to the Cundiboyacense plain, currently classified as vulnerable. The national programme to the catfish conservation, was used as a source for implementing the conservation plan in the CAR Cundinamarca in 2018. The present study performed the conservation status diagnosis of E. mutisii in Cundinamarca region which provides the basis for this conservation plan. In accordance, catfish geographical distribution was investigated by accessing biological collection information and conducting fish surveys of both lentic and lotic systems in pre-selection sites identified by the CAR officials and the research team. E. mutisii presence was evaluated in the Suarez, Bogota (high basin), Ubate, Veraguas, Frio, Aguas Claras and Muna rivers, also in the Fuquene lagoon and the Neusa and Tomine reservoirs. An electric fishing technique and physicochemical parameters measurement were used as the fish sampling approach of this study. The catfish catch per unit effort was 0.054 and 0.044 individuals/hour for rivers and lagoons (or reservoirs), respectively. A total of 17 individuals were captured, 53% of them were adults, 41% juveniles and 6% small fry. The length-weight relationship found indicates that the species growth was positive allometric. It was confirmed that catfish is geographically distributed in an elevation range of 2540–3000 masl, although it was not reported in the Bogota, Veraguas, Ubate, Suarez and Frio rivers. The decline of E. mutisii populations is mainly due to anthropic factors, such as transformation and fragmentation of ecosystems, introduction of invasive species and water bodies contamination.
