Critical interculturality, socio-linguistic theory and equity. The extraordinary story of a young offender

En este artículo se analiza cómo las personas que nacen y se educan en contextos desfavorecidos se socializan en una cultura y unos códigos que limitan sus posibilidades de desarrollo. Para profundizar sobre dicha cuestión consideramos un fragmento de la historia de vida de Samir Almasi1, un menor infractor que se convirtió en educador de menores tras cumplir un proceso de reforma juvenil. Una de las claves para que se produjese aquel extraordinario cambio fue que durante su infancia había adquirido una cultura que le permitía desenvolverse adecuadamente en cualquier entorno, no sólo en su contexto de origen. Aquella situación resultaba llamativa, porque la mayoría de sus compañeros en el centro de internamiento de menores infractores, no pudieron evolucionar tan favorablemente como él porque manejaban unos lenguajes de interacción, sobre todo comportamentales, muy alejados de los demandados por la sociedad. Hacemos una analogía de esa situación utilizando los códigos restringidos de la teoría socio-lingüística de Bernstein. Los resultados muestran que las personas que han experimentado una socialización limitante sufren una situación determinista que dificulta su emancipación fuera de su ambiente primario. Desde una perspectiva crítica intercultural se reivindica la de-construcción de las causas que generan esa situación y garantizar el desarrollo cultural de todas las personas, fundamentalmente, quienes proceden de entornos deprimidos culturalmente, en pos de una verdadera igualdad de oportunidades y de una sociedad inclusiva; ello debe ser una de las pretensiones de la educación obligatoria y públicaThis article discusses how people raised in disadvantaged contexts are socialized by specific cultural codes that limit their development. To illustrate it, a fragment of Samir Almasi's life history is presented. He was a minor offender who became an educator after a process of juvenile justice reform. One of the fundamental key related to this extraordinary change was the fact that during his childhood he had acquired a culture that allowed him to function adequately in any social environment, not only in his context of origin. Most of his colleagues in the centre of internment of juvenile offenders could not react and develop alike because they were socialized in specific languages of interaction, and behaviour not accepted by the majoritarian society. We make an analogy of that situation using the “restricted codes” notion from Bernstein's socio-linguistic theory. The results show that people who has experienced a culturally limited socialization makes emancipation unreachable outside of their primary environment. From a critical intercultural perspective, we argue that it is necessary to analyse the determinant factors of this unequal situation. Likewise, we argue for the acquisition of a minimum culture for all people, fundamentally, those from culturally depressed environments, in pursuit of a true equal opportunities and an inclusive society. The public education must be a guarantee of this cultural righ

Towards the Elucidation of Assimilative nasABC Operon Transcriptional Regulation in Haloferax mediterranei

The assimilatory pathway of the nitrogen cycle in the haloarchaeon Haloferax mediterranei has been well described and characterized in previous studies. However, the regulatory mechanisms involved in the gene expression of this pathway remain unknown in haloarchaea. This work focuses on elucidating the regulation at the transcriptional level of the assimilative nasABC operon (HFX_2002 to HFX_2004) through different approaches. Characterization of its promoter region using β-galactosidase as a reporter gene and site-directed mutagenesis has allowed us to identify possible candidate binding regions for a transcriptional factor. The identification of a potential transcriptional regulator related to nitrogen metabolism has become a real challenge due to the lack of information on haloarchaea. The investigation of protein–DNA binding by streptavidin bead pull-down analysis combined with mass spectrometry resulted in the in vitro identification of a transcriptional regulator belonging to the Lrp/AsnC family, which binds to the nasABC operon promoter (p.nasABC). To our knowledge, this study is the first report to suggest the AsnC transcriptional regulator as a powerful candidate to play a regulatory role in nasABC gene expression in Hfx. mediterranei and, in general, in the assimilatory nitrogen pathway.This research was funded by Universidad de Alicante, VIGROB-016

Response of Thawed Epidi dymal Red Deer Spermatozoa to Increasing Concentrations of Hydrogen Peroxide, and Importance of Individual Male Variability

P. 393-403Oxidative stress represents a challenge during sperm manipulation. We have tested the effect of increasing hydrogen peroxide (H2O2) levels on red deer spermatozoa after cryopreservation, and the role of male‐to‐male variation in that response. In a first experiment, eight thawed samples were submitted to 0, 25, 50, 100 and 200 μm H2O2 for 2 h at 37°C. Intracellular reactive oxygen species (H2DCFDA‐CM) increased with H2O2 concentration, but we only detected a decrease in sperm function (motility by CASA and chromatin damage by sperm chromatin structure assay) with 200 μm. Lipoperoxidation assessed by the thiobarbituric acid reactive substance (TBARS) method increased slightly with 50 μm H2O2 and above. In a second experiment, samples from seven males were submitted to 0 and 200 μm H2O2 for 2 h, triplicating the experiment within each male. Males differed at thawing and regarding their response to incubation and H2O2 presence. We found that the kinematic parameters reflected male‐to‐male variability, whereas the response of the different males was similar for lipid peroxidation and viability. A multiparametric analysis showed that males grouped differently if samples were assessed after thawing, after incubation without H2O2 or after incubation with H2O2. Red deer spermatozoa are relatively resilient to H2O2 after thawing, but it seems to be a great male‐to‐male variability regarding the response to oxidative stress. The acknowledgement of this individual variability might improve the development of optimized sperm work protocols.S

Virtualizing super-computation on-board UAS

Unmanned aerial systems (UAS, also known as UAV, RPAS or drones) have a great potential to support a wide variety of aerial remote sensing applications. Most UAS work by acquiring data using on-board sensors for later post-processing. Some require the data gathered to be downlinked to the ground in real-time. However, depending on the volume of data and the cost of the communications, this later option is not sustainable in the long term. This paper develops the concept of virtualizing super-computation on-board UAS, as a method to ease the operation by facilitating the downlink of high-level information products instead of raw data. Exploiting recent developments in miniaturized multi-core devices is the way to speed-up on-board computation. This hardware shall satisfy size, power and weight constraints. Several technologies are appearing with promising results for high performance computing on unmanned platforms, such as the 36 cores of the TILE-Gx36 by Tilera (now EZchip) or the 64 cores of the Epiphany-IV by Adapteva. The strategy for virtualizing super-computation on-board includes the benchmarking for hardware selection, the software architecture and the communications aware design. A parallelization strategy is given for the 36-core TILE-Gx36 for a UAS in a fire mission or in similar target-detection applications. The results are obtained for payload image processing algorithms and determine in real-time the data snapshot to gather and transfer to ground according to the needs of the mission, the processing time, and consumed watts.Unmanned aerial systems (UAS, also known as UAV, RPAS or drones) have a great potential to support a wide variety of aerial remote sensing applications.

Separate roles of PKA and EPAC in renal function unraveled by the optogenetic control of cAMP levels in vivo

Cyclic AMP (cAMP) is a ubiquitous second messenger that regulates a variety of essential processes in diverse cell types, functioning via cAMP-dependent effectors such as protein kinase A (PKA) and/or exchange proteins directly activated by cAMP (EPAC). In an intact tissue it is difficult to separate the contribution of each cAMP effector in a particular cell type using genetic or pharmacological approaches alone. We, therefore, utilized optogenetics to overcome the difficulties associated with examining a multicellular tissue. The transgenic photoactive adenylyl cyclase bPAC can be activated to rapidly and reversibly generate cAMP pulses in a cell-type-specific manner. This optogenetic approach to cAMP manipulation was validated in vivo using GAL4-driven UAS–bPAC in a simple epithelium, the Drosophila renal (Malpighian) tubules. As bPAC was expressed under the control of cell-type-specific promoters, each cAMP signal could be directed to either the stellate or principal cells, the two major cell types of the Drosophila renal tubule. By combining the bPAC transgene with genetic and pharmacological manipulation of either PKA or EPAC it was possible to investigate the functional impact of PKA and EPAC independently of each other. The results of this investigation suggest that both PKA and EPAC are involved in cAMP sensing, but are engaged in very different downstream physiological functions in each cell type: PKA is necessary for basal secretion in principal cells only, and for stimulated fluid secretion in stellate cells only. By contrast, EPAC is important in stimulated fluid secretion in both cell types. We propose that such optogenetic control of cellular cAMP levels can be applied to other systems, for example the heart or the central nervous system, to investigate the physiological impact of cAMP-dependent signaling pathways with unprecedented precision
