El desafío de las TICs para la universidad pública latinoamericana.

In this paper I analyze the institutional challenges of digitalization and increasing use of the new information and communication technologies (ICTs) for the processes of knowledge management in Latin American public universities. The discussion of these challenges is organized in two parts; in part one I deal with the difficulties created by knowledge privatization and, in particular, because of the worldwide features of privatization. In the second part I analyze the institutional consequences of the international mobility of highly skilled workers. Finally, I conclude with an outline of a proposal that describes the strategies and institutionalchanges that would permit the LatinAmerican public university to recover its visibility and reshape itself as a credible institutional actor by means of more pertinent and effective forms of knowledge management.En este trabajo se analizan los desafíos institucionales que representan la digitalización y uso masivo de las nuevas tecnologías de la información y comunicación (TICs) para la gestión del conocimiento en la universidad pública latinoamericana. La discusión de estos desafíos está organizada en dos secciones; en la primera de ellas se describen las dificultades creadas por la privatización en la producción de conocimientos y en particular por el carácter planetario de estos procesos privatizadores, y en la segunda sección se analizan las consecuencias institucionales de la creciente movilidad internacional de los trabajadores del conocimiento. El trabajo concluye con un una propuesta de estrategias y cambios institucionales que permitirían a la universidad pública latinoamericana recuperar su protagonismo y lograr formas más efectivas de gestión del conocimiento acordes a un nuevo entorno informatizado cada vez más exigente

A new displacement-based approach to calculate stress intensity factors with the boundary element method

The analysis of cracked brittle mechanical components considering linear elastic fracture mechanics is usually reduced to the evaluation of stress intensity factors (SIFs). The SIF calculation can be carried out experimentally, theoretically or numerically. Each methodology has its own advantages but the use of numerical methods has be-come very popular. Several schemes for numerical SIF calculations have been developed, the J-integral method being one of the most widely used because of its energy-like formulation. Additionally, some variations of the J-integral method, such as displacement-based methods, are also becoming popular due to their simplicity. In this work, a simple displacement-based scheme is proposed to calculate SIFs, and its performance is compared with contour integrals. These schemes are all implemented with the Boundary Element Method (BEM) in order to exploit its advantages in crack growth modelling. Some simple examples are solved with the BEM and the calculated SIF values are compared against available solutions, showing good agreement between the different schemes

Environmental Awareness of the Young in a Rural Community in the Sierra Tarahumara, Chihuahua, Mexico

With the aim at exploring the environmental awareness of the young sector in a predominantly indigenous community, fifty structured street interviews were applied to young individuals, aged 14 to 21, attending schools at Turuachi, a distant undeveloped rural community in the Sierra Tarahumara, in the State of Chihuahua, Northern Mexico. The data were analyzed by the software SPSS® (Statistical Package for Social Sciences). Most of the interviewees showed a good knowledge of basic ecology concepts. However, their perception of environmental problems appeared to be more influenced by everyday experiences. Despite forest being a major natural resource in the area, the group studied viewed cropping as the main economic activity. The main environmental problem was garbage pollution followed by deforestation and drought. The Chi2 test showed that women had a stronger perception than men about the garbage issue (p<0.057) and a clear disposition (p<0.001) to participate in municipal cleaning campaigns. Nearly all the participants were willing to engage in activities to preserve environmental quality; community action and specific workshops were selected as viable organization alternatives. Key words: environmental education, community participation, environmental problems

Simultaneous Orthogonal Planarity

We introduce and study the $\textit{OrthoSEFE}-k$ problem: Given $k$ planar graphs each with maximum degree 4 and the same vertex set, do they admit an OrthoSEFE, that is, is there an assignment of the vertices to grid points and of the edges to paths on the grid such that the same edges in distinct graphs are assigned the same path and such that the assignment induces a planar orthogonal drawing of each of the $k$ graphs? We show that the problem is NP-complete for $k \geq 3$ even if the shared graph is a Hamiltonian cycle and has sunflower intersection and for $k \geq 2$ even if the shared graph consists of a cycle and of isolated vertices. Whereas the problem is polynomial-time solvable for $k=2$ when the union graph has maximum degree five and the shared graph is biconnected. Further, when the shared graph is biconnected and has sunflower intersection, we show that every positive instance has an OrthoSEFE with at most three bends per edge.Comment: Appears in the Proceedings of the 24th International Symposium on Graph Drawing and Network Visualization (GD 2016

Concussion, Microvascular Injury, and Early Tauopathy in Young Athletes After Impact Head Injury and an Impact Concussion Mouse Model

The mechanisms underpinning concussion, traumatic brain injury, and chronic traumatic encephalopathy, and the relationships between these disorders, are poorly understood. We examined post-mortem brains from teenage athletes in the acute-subacute period after mild closed-head impact injury and found astrocytosis, myelinated axonopathy, microvascular injury, perivascular neuroinflammation, and phosphorylated tau protein pathology. To investigate causal mechanisms, we developed a mouse model of lateral closed-head impact injury that uses momentum transfer to induce traumatic head acceleration. Unanaesthetized mice subjected to unilateral impact exhibited abrupt onset, transient course, and rapid resolution of a concussion-like syndrome characterized by altered arousal, contralateral hemiparesis, truncal ataxia, locomotor and balance impairments, and neurobehavioural deficits. Experimental impact injury was associated with axonopathy, blood-brain barrier disruption, astrocytosis, microgliosis (with activation of triggering receptor expressed on myeloid cells, TREM2), monocyte infiltration, and phosphorylated tauopathy in cerebral cortex ipsilateral and subjacent to impact. Phosphorylated tauopathy was detected in ipsilateral axons by 24 h, bilateral axons and soma by 2 weeks, and distant cortex bilaterally at 5.5 months post-injury. Impact pathologies co-localized with serum albumin extravasation in the brain that was diagnostically detectable in living mice by dynamic contrast-enhanced MRI. These pathologies were also accompanied by early, persistent, and bilateral impairment in axonal conduction velocity in the hippocampus and defective long-term potentiation of synaptic neurotransmission in the medial prefrontal cortex, brain regions distant from acute brain injury. Surprisingly, acute neurobehavioural deficits at the time of injury did not correlate with blood-brain barrier disruption, microgliosis, neuroinflammation, phosphorylated tauopathy, or electrophysiological dysfunction. Furthermore, concussion-like deficits were observed after impact injury, but not after blast exposure under experimental conditions matched for head kinematics. Computational modelling showed that impact injury generated focal point loading on the head and seven-fold greater peak shear stress in the brain compared to blast exposure. Moreover, intracerebral shear stress peaked before onset of gross head motion. By comparison, blast induced distributed force loading on the head and diffuse, lower magnitude shear stress in the brain. We conclude that force loading mechanics at the time of injury shape acute neurobehavioural responses, structural brain damage, and neuropathological sequelae triggered by neurotrauma. These results indicate that closed-head impact injuries, independent of concussive signs, can induce traumatic brain injury as well as early pathologies and functional sequelae associated with chronic traumatic encephalopathy. These results also shed light on the origins of concussion and relationship to traumatic brain injury and its aftermath.awx350media15713427811001
