Analfabetismo y alfabetización en España (1835-1860).

Se presentan las primeras estadísticas oficiales sobre niveles de analfabetismo, cubriendo el período 1835-1842, es decir, unos veinte años antes del censo de 1860, cuando el Estado toma conciencia de las necesidades educativas e intenta elaborar una política educativa. Así, el análisis de los datos parciales presentados para los años 1835 y 1840-1842, y su comparación con los de 1860, permiten adelantar algunas tendencias generales de la alfabetización a fines del Antiguo Régimen y la transición con un nuevo modelo de alfabetización, consecuencia de los nuevos modelos educativos. La evolución entre 1840 y 1860, desde el punto de vista cuantitativo, muestra la estabilidad del fenómeno del analfabetismo. Estos datos confirman tendencias conocidas, y para el caso español, la estrecha relación entre alfabetismo y escolarización, así como, las permanencias y transformaciones en las prácticas socio-culturales.

Estad??stica escolar, proceso de escolarizaci??n y sistema educativo nacional en Espa??a (1750-1850)

Reconstruir la red o mapa escolar y determinar las tasas de escolarizaci??n cuantificando y recurriendo a fuentes estad??sticas y censos o recuentos escolares. Estudiar la ense??anza elemental o primaria de Espa??a, de 1750 a 1850, desde el punto de vista de las estad??sticas de procedencia estatal.. Se analiza el proceso de escolarizaci??n y su gen??sis, la articulaci??n y la consolidaci??n de los sistemas educativos nacionales. La investigaci??n se estructura en cuatro per??odos cronol??gicos: 1. 1749-1807. Este per??odo se caracteriza por la carencia de estad??sticas dirigidas a conocer la situacu??n de las escuelas de Primeras Letras, en contraste con lo sucedido en otros niveles educativos. 2. 1808-1833. Se instaura un nuevo sistema educativo (1814) y se sientan las bases legales para una estad??stica regular. 3. 1833-1842. El hecho m??s significativo es la aprobaci??n, en 1838 de la Ley de Ense??anza Primaria. 4. 1843-1850. Se observa la necesidad de crear un cuerpo de inspectores en el ??mbito provincial. Antonio Gil de Zarate se convierte en el Director General de Instrucci??n P??blica, situandose al frente de la administraci??n educativa central..

Durante el per??odo considerado se observa el progresivo desgajamiento de la informaci??n estad??stico-educativa de otros fines fiscales y de fomento, llegando a adquirir una naturaleza propia. Se observa que entre los pol??ticos y reformistas ilustrados de la ??poca no existe una defensa expl??cita de un sistema educativo nacional. Todos los datos obtenidos se deben entender en el entorno econ??mico y social que los hace inteligibles. La mayor parte de las fuentes estad??sticas consultadas est??n incompletas y,o dispersas..

O outro lado da implementação do LMD em França : um novo quadro para pensar as políticas de educação e de formação

O objectivo deste artigo é o de ir além da aparência de uma implementação suave do sistema LMD em França. Primeiro, o autor mostra um certo número de décalages. A universidade é enquadrada por redes que, por serem minoritárias, não deixam de ser menos importantes: as grandes écoles e o ensino superior não universitário. Esses sectores não entram no sistema 3.5.8. O essencial é, talvez, uma série de mudanças que adaptam o ensino superior ao novo espírito do capitalismo: uma organização em rede, uma filosofia social centrada sobre o projecto. Estas não estão directamente ligadas ao LMD mas apoiam-se neste novo contexto para progredir. Um cepticismo desenvolve-se sobre as vantagens do alongamento dos estudos. Uma nova concepção de justiça emerge, que advoga mais uma formação ao longo da vida. As medidas administrativas tomadas em nome do imperativo da accountability põem em execução um governo por normas de qualidade europeias. Enfim, a substituição de um quadro de referência nacional por um internacional conduz a uma mudança do modo de formação das elites. Não se trata tanto da reprodução da cultura clássica como de uma integração precoce em redes internacionais.

Estimates of global multicomponent aerosol optical depth and direct radiative perturbation in the Laboratoire de Météorologie Dynamique general circulation model

The global cycle of multicomponent aerosols including sulfate, black carbon (BC),organic matter (OM), mineral dust, and sea salt is simulated in the Laboratoire de Me´te´orologie Dynamique general circulation model (LMDZT GCM). The seasonal open biomass burning emissions for simulation years 2000–2001 are scaled from climatological emissions in proportion to satellite detected fire counts. The emissions of dust and sea salt are parameterized online in the model. The comparison of model-predicted monthly mean aerosol optical depth (AOD) at 500 nm with Aerosol Robotic Network (AERONET) shows good agreement with a correlation coefficient of 0.57(N = 1324) and 76% of data points falling within a factor of 2 deviation. The correlation coefficient for daily mean values drops to 0.49 (N = 23,680). The absorption AOD (ta at 670 nm) estimated in the model is poorly correlated with measurements (r = 0.27, N = 349). It is biased low by 24% as compared to AERONET. The model reproduces the prominent features in the monthly mean AOD retrievals from Moderate Resolution Imaging Spectroradiometer (MODIS). The agreement between the model and MODIS is better over source and outflow regions (i.e., within a factor of 2).There is an underestimation of the model by up to a factor of 3 to 5 over some remote oceans. The largest contribution to global annual average AOD (0.12 at 550 nm) is from sulfate (0.043 or 35%), followed by sea salt (0.027 or 23%), dust (0.026 or 22%),OM (0.021 or 17%), and BC (0.004 or 3%). The atmospheric aerosol absorption is predominantly contributed by BC and is about 3% of the total AOD. The globally and annually averaged shortwave (SW) direct aerosol radiative perturbation (DARP) in clear-sky conditions is �2.17 Wm�2 and is about a factor of 2 larger than in all-sky conditions (�1.04 Wm�2). The net DARP (SW + LW) by all aerosols is �1.46 and �0.59 Wm�2 in clear- and all-sky conditions, respectively. Use of realistic, less absorbing in SW, optical properties for dust results in negative forcing over the dust-dominated regions.

Investigating hydrological regimes and processes in a set of catchments with temporary waters in Mediterranean Europe

Seven catchments of diverse size in Mediterranean Europe were investigated in order to understand the main aspects of their hydrological functioning. The methods included the analysis of daily and monthly precipitation, monthly potential evapotranspiration rates, flow duration curves, rainfall runoff relationships and catchment internal data for the smaller and more instrumented catchments. The results showed that the catchments were less dry than initially considered. Only one of them was really semi-arid throughout the year. All the remaining catchments showed wet seasons when precipitation exceeded potential evapotrans-piration, allowing aquifer recharge, wet runoff generation mechanisms and relevant baseflow contribution. Nevertheless, local infiltration excess (Hortonian) overland flow was inferred during summer storms in some catchments and urban overland flow in some others. The roles of karstic groundwater, human disturbance and low winter temperatures were identified as having an important impact on the hydrological regime in some of the catchments.

Nonlinear regional warming with increasing CO₂ concentration

When considering adaptation measures and global climate mitigation goals, stakeholders need regional-scale climate projections, including the range of plausible warming rates. To assist these stakeholders, it is important to understand whether some locations may see disproportionately high or low warming from additional forcing above targets such as 2 K (ref. 1). There is a need to narrow uncertainty2 in this nonlinear warming, which requires understanding how climate changes as forcings increase from medium to high levels. However, quantifying and understanding regional nonlinear processes is challenging. Here we show that regional-scale warming can be strongly superlinear to successive CO2 doublings, using five different climate models. Ensemble-mean warming is superlinear over most land locations. Further, the inter-model spread tends to be amplified at higher forcing levels, as nonlinearities grow—especially when considering changes per kelvin of global warming. Regional nonlinearities in surface warming arise from nonlinearities in global-mean radiative balance, the Atlantic meridional overturning circulation, surface snow/ice cover and evapotranspiration. For robust adaptation and mitigation advice, therefore, potentially avoidable climate change (the difference between business-as-usual and mitigation scenarios) and unavoidable climate change (change under strong mitigation scenarios) may need different analysis methods.

ADCK3, an ancestral kinase, is mutated in a form of recessive ataxia associated with coenzyme Q(10) deficiency

Muscle coenzyme Q(10) (CoQ(10) or ubiquinone) deficiency has been identified in more than 20 patients with presumed autosomal-recessive ataxia. However, mutations in genes required for CoQ(10) biosynthetic pathway have been identified only in patients with infantile-onset multisystemic diseases or isolated nephropathy. Our SNP-based genome-wide scan in a large consanguineous family revealed a locus for autosomal-recessive ataxia at chromosome 1q41. The causative mutation is a homozygous splice-site mutation in the aarF-domain-containing kinase 3 gene (ADCK3). Five additional mutations in ADCK3 were found in three patients with sporadic ataxia, including one known to have CoQ(10) deficiency in muscle. All of the patients have childhood-onset cerebellar ataxia with slow progression, and three of six have mildly elevated lactate levels. ADCK3 is a mitochondrial protein homologous to the yeast COQ8 and the bacterial UbiB proteins, which are required for CoQ biosynthesis. Three out of four patients tested showed a low endogenous pool of CoQ(10) in their fibroblasts or lymphoblasts, and two out of three patients showed impaired ubiquinone synthesis, strongly suggesting that ADCK3 is also involved in CoQ(10) biosynthesis. The deleterious nature of the three identified missense changes was confirmed by the introduction of them at the corresponding positions of the yeast COQ8 gene. Finally, a phylogenetic analysis shows that ADCK3 belongs to the family of atypical kinases, which includes phosphomositide and choline kinases, suggesting that ADCK3 plays an indirect regulatory role in ubiquinone biosynthesis possibly as part of a feedback loop that regulates ATP production.

Fine root isotropy in Eucalyptus grandis plantations. Towards the prediction of root length densities from root counts on trench walls

The objectives of the study were to assess changes in fine root anisotropy and specific root lengths throughout the development of Eucalyptus grandis ( W. Hill ex Maiden) plantations and to establish a predictive model of root length density (RLD) from root intercept counts on trench walls. Fine root densities (<1 mm in diameter) were studied in 6-, 12-, 22-, 28-, 54-, 68- and 72-month-old E. grandis plantations established on deep Ferralsols in southern Brazil. Fine root intercepts were counted on 3 faces of 90-198 soil cubes (1 dm(3) in volume) in each stand and fine root lengths (L) were measured inside 576 soil cubes, sampled between the depths of 10 cm and 290 cm. The number of fine root intercepts was counted on one vertical face perpendicular to the planting row (N(t)), one vertical face parallel to the planting row (N(l)) and one horizontal face (N(h)), for each soil cube sampled. An overall isotropy of fine roots was shown by paired Student's t-tests between the numbers of fine roots intersecting each face of soil cubes at most stand ages and soil depths. Specific root lengths decreased with stand age in the upper soil layers and tended to increase in deep soil layers at the end of the rotation. A linear regression established between N(t) and L for all the soil cubes sampled accounted for 36% of the variability of L. Such a regression computed for mean Nt and L values at each sampling depth and stand age explained only 55% of the variability, as a result of large differences in the relationship between L and Nt depending on stand productivity. The equation RLD=1.89*LAI*N(t), where LAI was the stand leaf area index (m(2) m(-2)) and Nt was expressed as the number of root intercepts per cm(2), made it possible to predict accurately (R(2)=0.84) and without bias the mean RLDs (cm cm(-3)) per depth in each stand, for the whole data set of 576 soil cubes sampled between 2 years of age and the end of the rotation.

Parâmetros de produção de leite de búfala fermentado por Lactobacillus casei

O leite de búfala foi fermentado por Lactobacillus casei, com diferentes concentrações de açúcar e tempos de fermentação, e estocado durante 30 dias a 5 e 10°C. Avaliaram-se a acidez, o pH e a viabilidade de L. casei nos diferentes tratamentos. O leite fermentado por 18 horas não apresentou os parâmetros requeridos para o produto, enquanto os fermentados por 22 e 24 horas apresentaram acidez e pH adequados. O tempo e a temperatura de estocagem influenciaram esses parâmetros. A viabilidade de L. casei inicial foi maior que 9 log UFC mL^-1 e a final, maior que 8 log UFC mL^-1, com influência da acidez.

Position paper from the IBRA Symposium on Surgery of the Head - The 2nd International Symposium for Condylar Fracture Osteosynthesis, Marseille, France 2012

Background: This is a position paper from the 2nd International Bone Research Association (IBRA) Symposium for Condylar Fracture Osteosynthesis 2012 was held at Marseille, succeeding the first congress in Strasbourg, France, in 2007. The goal of this IBRA symposium and this paper was to evaluate current trends and potential changes of treatment strategies for mandibular condylar fractures, which remain controversial over the past decades.Methods: Using a cross-sectional study design, we enrolled the consensus based on the panel of experts and participants in the IBRA Symposium 2012. The outcomes of interest were the panel and electronic votes on management of condylar base, neck and head fractures, and panel votes on endoscopic and paediatric condylar fractures. Appropriate descriptive and univariate statistics were used.Results: The consensus derived from 14 experts and 41 participant surgeons, using 12 case scenarios and 27 statements. The experts and participants had similar decision on the treatment of condylar base, neck and head fractures, as well as similar opinion on complications of condylar fracture osteosynthesis. They had a parallel agreement on using open reduction with internal fixation (ORIF) as treatment of choice for condylar base and neck fractures in adults. Endoscopic approaches should be considered for selected cases, such as condylar base fractures with lateral displacement. There was also a growing tendency to perform ORIF in condylar head fractures. The experts also agreed to treat children (> 12 years old) in the same way as adults and to consider open reduction in severely displaced and dislocated fractures even in younger children. Nevertheless, non-surgical treatment should be the first choice for children <6 years of age. The decision to perform surgery in children was based on factors influencing facial growth, appropriate age for ORIF, and disagreement to use resorbable materials in children.Conclusions: The experts and participating surgeons had comparable opinion on management of condylar fractures and complications of ORIF. Compared to the first Condylar Fracture Symposium 2007 in Strasbourg, ORIF may now be considered as the gold standard for both condylar base and neck fractures with displacement and dislocation. Although ORIF in condylar head fractures in adults and condylar fractures in children with mixed dentition is highly recommended, but this recommendation requires further investigations.
