This material may be found at https://ascelibrary.org/doi/abs/10.1061/%28ASCE%29CP.1943-5487.0000908. ; This paper depicts a set of virtual reality (VR) and augmented reality (AR) applications conceived for the enrichment of laboratory experiences within the field of structural engineering. The experimental program corresponds to the study of beams, columns, and frames of austenitic stainless steel subjected to different types of static loading. The development of these applications encompasses the use of measured data from sensors, the use of 3D modeling tools, the use of game engines, and the corresponding mathematical treatment and postprocess of the structural tests in a real-time fashion. The developed applications provide new possibilities for structural engineering laboratory experiences. In both cases (VR and AR), the developed applications are meant to enhance the experimental program experience to a variety of target users (researchers, technicians, students) by adding customized information related to the structural behavior of all elements during the tests as well as to basic concepts of health and safety in structural engineering laboratories. ; This experimental program was developed in the frame of Project BIA2016-75678-R, AEI/FEDER, UE "Comportamiento estructural de pórticos de acero inoxidable. Seguridad frente a acciones accidentales de sismo y fuego," funded by the MINECO (Spain). Financial support from the Industrial Doctorate program (Ref. ID.:2017-DI-069) of AGAUR, Government of Catalonia, is acknowledged by the third author. ; Peer Reviewed ; Postprint (author's final draft)

Lavado de activos: riesgos y consecuencias socioeconómicas en la frontera colombo-venezolana
In: Revista de Relaciones Internacionales, Estrategia y Seguridad, Band 18, Heft 2, S. 105-116
ISSN: 1909-7743
El siguiente artículo de revisión documental analiza los riesgos y consecuencias socioeconómicas del lavado de activos en la zona fronteriza de Colombia y Venezuela (Norte de Santander-Táchira), por medio de la minería de textos y la exploración documental, con la finalidad de identificar los principales efectos negativos que trae consigo el blanqueo de capitales en el desarrollo del país y las consecuencias adversas que dicha actividad acarrea para el crecimiento económico de la región; se caracterizan factores específicos, como la economía subterránea, y los efectos desfavorables para el desarrollo de la sociedad. Se llega a la conclusión de que en las zonas fronterizas tiene mayor incidencia esta práctica delictiva, ya que el contrabando, que es una forma frecuente de blanquear capital, está allí más presente que en zonas céntricas del país. Esto puede deberse a la dificultad, por parte del Estado, de auditar las operaciones bilaterales fronterizas.

A review and meta-analysis of the effects of climate change on Holarctic mountain and upland bird populations
Mountain regions are globally important areas for biodiversity but are subject to multiple human-induced threats, including climate change, which has been more severe at higher elevations. We reviewed evidence for impacts of climate change on Holarctic mountain bird populations in terms of physiology, phenology, trophic interactions, demography and observed and projected distribution shifts, including effects of other factors that interact with climate change. We developed an objective classification of high-elevation, mountain specialist and generalist species, based on the proportion oftheir breeding range occurring in mountain regions. Our review found evidence of responses of mountain bird populations to climate (extreme weather events, temperature, rainfall and snow) and environmental (i.e. land use) change, but we know little about either the underlying mechanisms or the synergistic effects of climate and land use. Long-term studies assessing reproductive success or survival of mountain birds in relation to climate change were rare. Few studies have considered shifts in elevational distribution over time and a meta-analysis did not find a consistent direction in elevation change. A meta-analysis carried out on future projections of distribution shifts suggested that birds whose breeding distributions are largely restricted to mountains are likely to be more negatively impacted than other species. Adaptation responses to climate change rely mostly on managing and extending current protected areas for both species already present, and for expected colonizing species that are losing habitat and climate space at lower elevation. However, developing effective management actions requires an improvement in the current knowledge of mountain species ecology, in the quality of climate data and in understanding the role of interacting factors. Furthermore, the evidence was mostly based on widespread species rather than mountain specialists. Scientists should provide valuable tools to assess the status of mountain birds, for example through the development of a mountain bird population index, and policy-makers should influence legislation to develop efficient agri-environment schemes and forestry practices for mountain birds, as well as to regulate leisure activities at higher elevations. ; Peer reviewed
