The Agendas 21 of the Cordoba province. The identification of sustainability indicators, their diffusion and their impact on decision making

En la provincia de Córdoba se está consolidando la implantación de Agendas 21 tanto en lo que respecta a las Agendas 21 Locales como a la Agenda 21 Provincial. Una vez superadas las etapas iniciales, en la cuales se sientan las bases del proceso y se desarrolla la planificación estrategia hacia la sostenibilidad, resulta necesario plantear la puesta en valor de los logros alcanzados, sobre todo considerando la explotación de los indicadores de sostenibilidad ya determinadosIn the Cordoba province is consolidating the implenentation of Agenda 21 as in regard to Local Agenda 21 as to the Provincial. Once you get past the initial stages, in which the foundations of the process and develop the planning strategy towards sustainability, it is necessary to consider the enhancement of the achievements, above all considering the use of sustainability indicators already certainPeer Reviewe

Vacuum fluctuations and the conditional homodyne detection of squeezed light

Conditional homodyne detection of quadrature squeezing is compared with standard nonconditional detection. Whereas the latter identifies nonclassicality in a quantitative way, as a reduction of the noise power below the shot noise level, conditional detection makes a qualitative distinction between vacuum state squeezing and squeezed classical noise. Implications of this comparison for the realistic interpretation of vacuum fluctuations (stochastic electrodynamics) are discussed.Comment: 14 pages, 7 figures, to appear in J. Opt.

Why the embryo still matters: CSF and the neuroepithelium as interdependent

Producción CientíficaThe key focus of this review is that both the neuroepithelium and embryonic cerebrospinal fluid (CSF) work in an integrated way to promote embryonic brain growth, morphogenesis and histiogenesis. The CSF generates pressure and also contains many biologically powerful trophic factors; both play key roles in early brain development. Accumulation of fluid via an osmotic gradient creates pressure that promotes rapid expansion of the early brain in a developmental regulated way, since the rates of growth differ between the vesicles and for different species. The neuroepithelium and ventricles both contribute to this growth but by different and coordinated mechanisms. The neuroepithelium grows primarily by cell proliferation and at the same time the ventricle expands via hydrostatic pressure generated by active transport of Na+ and transport or secretion of proteins and proteoglycans that create an osmotic gradient which contribute to the accumulation of fluid inside the sealed brain cavity. Recent evidence shows that the CSF regulates relevant aspects of neuroepithelial behavior such as cell survival, replication and neurogenesis by means of growth factors and morphogens. Here we try to highlight that early brain development requires the coordinated interplay of the CSF contained in the brain cavity with the surrounding neuroepithelium. The information presented is essential in order to understand the earliest phases of brain development and also how neuronal precursor behavior is regulated

Dataplane Specialization for High-performance OpenFlow Software Switching

OpenFlow is an amazingly expressive dataplane program- ming language, but this expressiveness comes at a severe performance price as switches must do excessive packet clas- sification in the fast path. The prevalent OpenFlow software switch architecture is therefore built on flow caching, but this imposes intricate limitations on the workloads that can be supported efficiently and may even open the door to mali- cious cache overflow attacks. In this paper we argue that in- stead of enforcing the same universal flow cache semantics to all OpenFlow applications and optimize for the common case, a switch should rather automatically specialize its dat- aplane piecemeal with respect to the configured workload. We introduce ES WITCH , a novel switch architecture that uses on-the-fly template-based code generation to compile any OpenFlow pipeline into efficient machine code, which can then be readily used as fast path. We present a proof- of-concept prototype and we demonstrate on illustrative use cases that ES WITCH yields a simpler architecture, superior packet processing speed, improved latency and CPU scala- bility, and predictable performance. Our prototype can eas- ily scale beyond 100 Gbps on a single Intel blade even with complex OpenFlow pipelines

Alzheimer’s disease (AD) knowledge in Korean Americans: identifying knowledge gaps and misconceptions and examining predictors of AD knowledge

Objectives: This study examined Alzheimer’s disease (AD) knowledge and its predictors among Korean Americans (KAs). Design: Convenience sampling was used to recruit KAs in the Greater Washington metropolitan area. A total of 268 KAs participated in the study and completed a cross-sectional survey in 2014. Using the Alzheimer’s Disease Knowledge Scale (ADKS), overall and domain knowledge was assessed. Multiple regression analyses were conducted for overall and domain knowledge with predictors including exposure to AD, social engagement, sources and frequency of health-related information, stigmatic beliefs (pity, antipathy, and social distance), English proficiency, and education. Results: KAs reported a 59% accuracy in the overall AD knowledge. At the domain level, KAs were most knowledgeable about assessment and diagnosis and least knowledgeable about caregiving. Our regression analyses showed that having a college degree or higher is associated with a greater overall AD knowledge. Three domain models of life impact, risk factors, and caregiving turned out to be significant: Having a college degree or higher is a predictor of greater knowledge in all three domains. Having more pity stigmatic beliefs is related to greater knowledge in both life impact and caregiving domains while having less pity stigmatic beliefs is associated with more risk factor knowledge; having less social distance stigmatic beliefs is associated with greater life impact knowledge; and having less antipathy stigmatic beliefs is related to better caregiving knowledge. Conclusion: Our findings revealed areas of misconceptions and knowledge gaps in KAs which need to be addressed in educational interventions. Different knowledge status across the domains demonstrates a multi-dimensional nature of AD knowledge. Multivariate findings confirmed the robust role of education in overall and domain AD knowledge. The effect of different AD stigmatic beliefs on certain AD knowledge domains suggests ways of how stigma change can be efficient for the purpose of increasing AD domain knowledge in KAs

Testing the Modified Press-Schechter Model against N-Body Simulations

A modified version of the extended Press-Schechter model for the growth of dark-matter haloes was introduced in two previous papers with the aim at explaining the mass-density relation shown by haloes in high-resolution cosmological simulations. In this model major mergers are well separated from accretion, thereby allowing a natural definition of halo formation and destruction. This makes it possible to derive analytic expressions for halo formation and destruction rates, the mass accretion rate, and the probability distribution functions of halo formation times and progenitor masses. The stochastic merger histories of haloes can be readily derived and easily incorporated into semi-analytical models of galaxy formation, thus avoiding the usual problems encountered in the construction of Monte Carlo merger trees from the original extended Press-Schechter formalism. Here we show that the predictions of the modified Press-Schechter model are in good agreement with the results of N-body simulations for several scale-free cosmologies.Comment: 17 pages including 7 figures, MNRAS in pres

Ethical Challenges of the Industry: Are Graduates Prepared?

Hospitality graduates often enter their first jobs unaware of the difficult ethical dilemmas they will face. By having ethics teaching in a curriculum, the authors of this article believe that the perceptions of ethics of senior hospitality students at Northern Arizona University were comparable to those of operating industry managers
