A Challenge for Teachers of Inclusive Higher Education
The paper shows the results of a research process that aimed to analyze the pedagogical strategies applied by teachers in the academic process to students with disabilities at the Technical University of Manabí, thus raising the challenge of training professionals in Higher Education. For this purpose, a qualitative-quantitative methodology was used in which 50 teachers were surveyed, which allowed obtaining the required information. The paper presents the ideas offered by teachers about inclusive education, which leads the institution to reflect to refine strategies that promote management in an inclusive education system. Through the development of the research, it was possible to verify the disposition of the teaching staff of the Technical University of Manabi, to continue reinforcing the inclusive policy drawn up by the government and particularly by the direction of the educational institution
Dry and wet rainy seasons in the Mantaro river basin (Central Peruvian Andes)
International audienceMonthly precipitation data from the period of 1970 to 2004 from 38 meteorological stations in the Mantaro river basin were used to classify the rainy seasons (September?April) of each year into anomalously dry or wet, and to determine the basin-wide extent of the anomalies based on the Standardized Precipitation Index (SPI). The wet periods mostly occurred in the early 1970's and during the first half of the 1980's, except for the event that occurred in the 1993/94 period which was the strongest and most generalized in the analyzed period. The dry periods occurred mostly during the second half of the 1980's and the 1990's. Consistent with this, a negative trend in precipitation of 2% per decade was found for the rainy season, due mainly to a stronger trend (?4%/decade) during the peak phase (January?March). Despite previously reported significant negative correlations between El Niño-Southern Oscillation (ENSO) and rainfall during the peak of the rainfall season, the similar amplitude variability of precipitation during the onset phase of the rainfall season (September?December), which is uncorrelated with ENSO, participate to the reduction of the absolute correlation for the full rainfall season. Correlations between rainfall in the Mantaro basin and sea surface temperature (SST) in the tropical Atlantic are significant only near the end of the rainy season, with more rain associated with a weaker north-south difference in SST in the tropical Atlantic
Allele specific expression analysis identifies regulatory variation associated with stress-related genes in the Mexican highland maize landrace Palomero Toluqueño.
BackgroundGene regulatory variation has been proposed to play an important role in the adaptation of plants to environmental stress. In the central highlands of Mexico, farmer selection has generated a unique group of maize landraces adapted to the challenges of the highland niche. In this study, gene expression in Mexican highland maize and a reference maize breeding line were compared to identify evidence of regulatory variation in stress-related genes. It was hypothesised that local adaptation in Mexican highland maize would be associated with a transcriptional signature observable even under benign conditions.MethodsAllele specific expression analysis was performed using the seedling-leaf transcriptome of an F1 individual generated from the cross between the highland adapted Mexican landrace Palomero Toluqueño and the reference line B73, grown under benign conditions. Results were compared with a published dataset describing the transcriptional response of B73 seedlings to cold, heat, salt and UV treatments.ResultsA total of 2,386 genes were identified to show allele specific expression. Of these, 277 showed an expression difference between Palomero Toluqueño and B73 alleles under benign conditions that anticipated the response of B73 cold, heat, salt and/or UV treatments, and, as such, were considered to display a prior stress response. Prior stress response candidates included genes associated with plant hormone signaling and a number of transcription factors. Construction of a gene co-expression network revealed further signaling and stress-related genes to be among the potential targets of the transcription factors candidates.DiscussionPrior activation of responses may represent the best strategy when stresses are severe but predictable. Expression differences observed here between Palomero Toluqueño and B73 alleles indicate the presence of cis-acting regulatory variation linked to stress-related genes in Palomero Toluqueño. Considered alongside gene annotation and population data, allele specific expression analysis of plants grown under benign conditions provides an attractive strategy to identify functional variation potentially linked to local adaptation
Population Relationship of Three Forestry Species, Aegiphila ferruginea, Oreopanax ecuadorensis, Vallea stipularis; in the Leonan de Llucud Forest, Chambo Canton, Chimborazo Province
The present investigation aims to relate the population of three native forest species of the Andean region of Ecuador: Oreopanax ecuadorensis Seem, Aegiphila ferruginea, and Vallea stipularis in the Leonan de Llucud high montane evergreen forest located in the Chambo canton. Through the inventory and observation of the distribution of these three species in three altitudinal floors, establishing ten plots within which circular subplots of five meters radius were placed, taking the species under study as the center, all individuals with diameter at breast height greater than or equal to 7 cm were selected. For each altitudinal floor, the Importance Value Index, the Simpson and Shannon-Weaver Biodiversity Indices, and the Sorensen Similarity Index were calculated. The results presented below are the result of the data obtained in the field and its interpretation. V. stipularis and O. ecuadorensis Seem show a close relationship, while A. ferruginea has a low population due to the exploitation it is subjected to in this forest, thus asserting the presence of this species in the red book at a near-threatened level.
Keywords: evergreen forest, native forest species, altitudinal floors.
Resumen
La presente investigación pretende relacionar la población de tres especies forestales nativas de la región andina del Ecuador Oreopanax ecuadorensis Seem, Aegiphila ferruginea y Vallea stipularis en el bosque siempre verde montano alto Leonan de Llucud ubicado en el cantón Chambo; mediante la inventariación y observación de la distribución de estas tres especies en tres pisos altitudinales, estableciendo diez parcelas dentro de las cuales se colocaron subparcelas circulares de cinco metros de radio tomando como centro a las especies en estudio, se seleccionaron todos los individuos con Diámetro a la Altura del Pecho, mayor o igual a 7 cm. Para cada piso altitudinal se calculó el Índice de Valor de Importancia, los Índices de biodiversidad de Simpson y Shannon – Weaver y el Índice de similitud de Sorensen. Los resultados que a continuación presentamos son resultado de los datos obtenidos en campo y su interpretación. Teniendo que V. stipularis y O. ecuadorensis Seem presentan gran afinidad; en tanto que A. ferruginea presenta una baja poblacional debido a la explotación a la cual es sometida en este bosque, aseverándose así la presencia de esta especie en el libro rojo en nivel de casi amenazado.

Co-enforcement of Common Pool Resources: Experimental Evidence from TURFs in Chile
This work presents the results of framed field experiments designed to study the co-enforcement of access to common pool resources. The experiments were conducted in the field with participants in the territorial use rights in fisheries (TURFs) management scheme that regulates access to nearshore fisheries along the coast of Chile. In the experiments, TURF members not only decided on harvest but also invested in monitoring to deter poaching by outsiders. Treatments varied whether the monitoring investment was an individual decision or determined by a group vote. Per-unit sanctions for poaching were exogenous as if provided by a government authority, and we varied the sanction level. Our results suggest that co-enforcement, in which monitoring for poaching is provided by resource users and sanctions are levied by the government, can reduce poaching levels. Monitoring investments were not high enough to lift the expected marginal penalty for poaching above the marginal gain from poaching when the sanction for poaching was low, but expected marginal penalties were higher than the marginal gain from poaching when the sanction was high. Despite this, poaching levels were not sensitive to changes in monitoring levels and sanctions. While co-enforcement did not eliminate poaching, it did eliminate the gains from poaching in all but one treatment
ADSORPTION ESSAYS OF PALLADIUM IN MODIFIED SILICA GEL WITH THIOURONIUM GROUPS: EXPERIMENTAL AND THEORICAL STUDIES
Indexación: Web of Science; ScieloThe silylant 3-cloropropyltriethoxysilyl was anchored over silica gel in anhydrous conditions in order to react with thiourea to obtain modified silica gel with thiouronium. The aim to obtain an inorganic support that is able to hijack metals from the VIII group such as palladium. The product was characterized by Sbet and FTIR infrared spectroscopy. For the determination of the structure in the modified silica gel NMR spectra of silicon and carbon were preformed in solid state. The coordination form of the modified silica gel to the metal was studied computationally in the context of the DFT theory, using the ADF code. This was a collaborative work with "Fundación Chile" for the recuperation of precious metals from the mining industry.http://ref.scielo.org/gk7rm
Growth rate controls mRNA turnover in steady and non-steady states
Gene expression has been investigated in relation with growth rate in the yeast Saccharomyces cerevisiae, following different experimental strategies. The expression of some specific gene functional categories increases or decreases with growth rate. Our recently published results have unveiled that these changes in mRNA concentration with growth depend on the relative alteration of mRNA synthesis and decay, and that, in addition to this gene-specific transcriptomic signature of growth, global mRNA turnover increases with growth rate. We discuss here these results in relation with other previous and concurrent publications, and we add new evidence which indicates that growth rate controls mRNA turnover even under non-steady-state conditions.Ministerio de Economía, Industria y Competitividad BFU2013-48643-C3-3-PMinisterio de Economía, Industria y Competitividad BFU2013-48643-C3-1-PUnión Europea Fondos FEDERGeneralitat Valenciana PROMETEO II 2015/006Junta de Andalucía P12-BIO1938M

Translation and validation of the WHO-5 General well-being index into native language Quechua of the Peruvian South
To translate and validate the WHO-5 General Well-being Index for the people of the Peruvian South, a cross-sectional instrumental study was carried out with the voluntary participation of 186 people of both sexes between the ages of 18 and 65 years (M = 29.67 years old; SD = 10.94) living in the south region of Peru. The validity evidence was assessed based on the content using Aiken’s coefficient V according to the internal structure through a confirmatory factor analysis, and reliability was calculated through Cronbach’s alpha coefficient. The expert judgment was favorable for all items (V > 0.70). The unidimensional structure of the scale was confirmed (χ2 = 10.86, df = 5, p = 0.05; RMR = 0.020; GFI = 0.980; CFI = 0.990; TLI = 0.980 y RMSEA = 0.080), and it presents a suitable reliability range (α = > 0.75). This shows that the WH
