User Experience Design Manifesto

The rapid change of the elements of context requires an urgent reflection on "Experience" and "Meaning with Value". The aim of this article is to critically review the User Experience Design (UXD) as a disciplinary field, and contribute by a Manifesto to an inspiring vision of the future. Some authors will be reviewed in order to list and discuss the different ideas to redefine the desirable skills to an enlightened practice and to influence a new ethos of "Be Innovation" to a better world. The article retrieves and revisits a Design Manifesto made on the basis of a strategic vision for Design based on distinctive design competencies. This Manifesto was in the origin of the platform www.inspaedia.com.CITAD – Centro de Investigação em Território, Arquitetura e Design, Universidades de Lusíada, Portugal; CIAUD – Centro de Investigação em Arquitetura, Urbanismo e Design, Faculdade de Arquitetura, Universidade de Lisboa, Portugal.

The Upper Bound Theorem in forging processes: Model of Triangular Rigid Zones on parts with horizontal symmetry

The analysis to determine the necessary forces with which to achieve a plastic deformation in metallic materials, in particular, in forging processes and under conditions of plain strain, has been raised over the years through a double approach; on the one hand, by analytical methods that involve a great complexity in their developments but that allow a direct understanding of the parameters that direct these processes. On the other hand, numerical methods, in which, thanks to the enormous development of computer technology, they provide solutions with a high approximation but, in most cases, do not allow to interpret independently the effect of each one of the parameters that come into play. The development of computers relegated analytical methods to the background. An alternative of great interest to apply these methods comes from the study of the Upper Bound Theorem by means of the Triangular Rigid Zones (TRZ) Model. One of the main limitations in the application of this model come from the fact that it is necessary to define a kinematically admissible velocity field and for complex geometric configurations of parts, this field becomes increasingly complicated. A new approach has delimited, from a theoretical perspective, a modular configuration based on a General Module formed by three TRZ that adapts to any geometry of flat surfaces of the part. Another limitation of the Upper Bound Method is the consideration of the plain strain represented by a flat section with double symmetry. Obviously, this imposition only allows to study a limited number of part configurations, which restricts its application in forging processes since the great majority of forged parts do not present geometrically this double symmetry. The present work releases one of these boundary conditions allowing to expand the possibilities of application of this method.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tec

Integrating archaeology and ancient DNA analysis to address invasive species colonization in the Gulf of Alaska

The intentional and unintentional movement of plants and animals by humans has transformed ecosystems and landscapes globally. Assessing when and how a species was introduced are central to managing these transformed landscapes, particularly in island environments. In the Gulf of Alaska, there is considerable interest in the history of mammal introductions and rehabilitating Gulf of Alaska island environments by eradicating mammals classified as invasive species. The Arctic ground squirrel (Urocitellus parryii) is of concern because it affects vegetation and seabirds on Gulf of Alaska islands. This animal is assumed to have been introduced by historic settlers; however, ground squirrel remains in the prehistoric archaeological record of Chirikof Island, Alaska, challenge this timeline and suggest they colonized the islands long ago. We used 3 lines of evidence to address this problem: direct radiocarbon dating of archaeological squirrel remains; evidence of prehistoric human use of squirrels; and ancient DNA analysis of dated squirrel remains. Chirikof squirrels dated to at least 2000 years ago, and cut marks on squirrel bones suggested prehistoric use by people. Ancient squirrels also shared a mitochondrial haplotype with modern Chirikof squirrels. These results suggest that squirrels have been on Chirikof longer than previously assumed and that the current population of squirrels is closely related to the ancient population. Thus, it appears ground squirrels are not a recent, human‐mediated introduction and may have colonized the island via a natural dispersal event or an ancient human translocation.We thank T. Rick, D.

Políticas públicas en la era digital y el impacto en los medios digitales radiales de la Provincia de San Luis, Argentina

Con la llegada de las tecnologías, el ámbito público se extendió más allá de las calles o de los mas media y encontró en los espacios digitales el lugar donde es posible visibilizar temas y miradas de sujetos que no tenían acceso a grandes empresas de comunicación. Desde el advenimiento a la democracia, los gobiernos argentinos impulsaron reformas para regular la radiodifusión y políticas de comunicación; con las nuevas tecnologías, lo digital ha constituido un tópico a trabajar y a tener en cuenta por el gobierno nacional y en este caso, por el de la Provincia de San Luis. En el ámbito académico, conocer los medios de comunicación de masas era una necesidad que a raíz de las nuevas tecnologías fue mutando. Es por ello y enmarcado en los objetivos del proyecto, se presentan primeros resultados que incluyen: mapa de medios digitales radiales, políticas públicas vigentes desde el 1/1/2012 hasta el 31/12/2014, en relación a las nuevas tecnologías de la información y la comunicación (TIC) y finalmente una aproximación estadística sobre la relación políticas públicas y medios digitales radiales de la Provincia de San Luis.Fil: Maldonado, Ana Silvina.

Influence of the duration of a treadmill walking bout on heart rate variability at rest in physically active women

Background: Heart rate variability (HRV) has been promoted as a noninvasive method of evaluating autonomic influence on cardiac rhythm. Although female subjects predominate in the walking studies, no study to date has examined the influence of the duration of a moderate intensity walking physical activity bout on HRV in this population. Methods: Twelve healthy physically active middle-aged women undertook 2 conditions; 20min (W20) and 60min (W60) bouts of walking on a treadmill. Resting HRV measures were obtained before (-1 h), and 1 h and 24 h after the walking bouts. Results: Mean NN interval (ie, normal-to-normal intervals between adjacent QRS complexes) was significantly lower (P = .017) at +1 h in W60 (832, 686-979ms) compared with W20 (889, 732-1046ms). A borderline main effect for time was observed for both the SDNN intervals in W60 (P = .056), and for low frequency (LF(abs)) power in W60 (P = .047), with post hoc tests revealing a significant increase between 1 h (51, 33-69 ms and 847, 461-1556 ms(2)) and +1 h (65, 34-97ms and 1316, 569-3042 ms(2)) for SDNN and LF(abs) power, respectively, but no increase at +24h compared with -1 h. Conclusions: It appears that a walking bout of 60 min duration does alter cardiac autonomic influence in healthy active women, and this alteration is not evident after 20 min of walking. Given the rather subtle effect, further studies with larger sample sizes are required to explore the nature of the changes in cardiac autonomic influence following a prolonged bout of walking

Políticas públicas en medios de comunicación digitales : el caso de los principales periódicos online de la provincia de San Luis, República Argentina

Las políticas públicas pueden ser comprendidas desde una visión amplia que analice tanto las relaciones entre las prácticas sociales y sus actores como así también el rol que estas prácticas ejercen en su diseño, implementación, seguimiento y evaluación. En este trabajo se analizan las políticas públicas de comunicación ejercidas desde los principales periódicos online de la provincia de San Luis, República Argentina y sus efectos en la construcción de ciudadanía. Para su organización se presenta una breve introducción y definición teórica de los conceptos implicados, considerando el rol que el estado y los medios de comunicación ejercen en un gobierno de mocrático, en función de las normativas vigentes. Posteriormente, se desarrolla el estudio en función de una selección de medios periodísticos online y sus efectos en relación a los derechos de acceso a la información, libertad de expresión y participación de los ciudadanos lectores. Finalmente, se cierra con unas primeras aproximaciones.Fil: Ponce, Viviana. Universidad Nacional de San LuisFil: Maldonado, Silvina. Universidad Nacional de San LuisFil: Chiarani, Rodrigo.
