Por ultimo se pretende despertar un interés por identificar y mejorar el papel de los distintos tipos de lenguaje de la información en las investigacione

Propuesta para la enseñanza de la suma de fracciones desde la representación gráfica

Se hace necesario que los estudiantes den significado y sentido a las fracciones, no desde el punto de vista algorítmico, sino apoyados en la representación gráfica y concreta, relacionándolas en contexto continuo y discreto; reconociendo la importancia de conservar la unidad como un aspecto primordial para comprender la relación entre la parte y el todo; continuando con el reconocimiento de las equivalencias entre las fracciones, reconociendo las partes que se relacionan con el todo, lo que conlleva a hallar el común de las partes de la unidad, para luego realizar el proceso de suma de fracciones, despojándolas de la suma habitual de fracciones dada a partir del algoritmo

Post-adoption help-seeking in Portugal: a Comprehensive study on parental difficulties and help-seeking behaviors and perceptions

Effective psychological parenting interventions delivered to adoptive parents may prevent serious adjustment difficulties and promote a healthy functioning; however, less is known about adoptive parents’ specific parental difficulties and help-seeking behaviors and perceptions, the understanding of which is deemed necessary to design well-informed interventions. This study aimed to describe parental difficulties, help-seeking behaviors, satisfaction with, and perceived barriers to seek, professional help, and acceptability of psychological parenting interventions among Portuguese adoptive parents. Comparisons with biological parents (Study 1) and between adoptive parents that requested adoption-specialized and non-specialized support (i.e., adoption-specialized vs. non-specialized help-seekers) (Study 2) were explored. A cross-sectional online survey was conducted. Participants were 471 adoptive and 552 biological parents of children aged under 18 years who were recruited through schools, adoption agencies, and social networks. They completed measures assessing parental difficulties, help-seeking behaviors, satisfaction with, and perceived barriers to seek, professional help, and acceptability of psychological parenting interventions. Comparison tests between the study groups, Pearson’s correlations, analyses of covariance (ANCOVA) and multivariate logistic regressions (MLR) were performed. Parents’ well-being and normative parenting challenges were the most frequent difficulties in both groups, but only associated with adoptive parents’ help-seeking. Although difficulties related to a child’s problems/parent–child relationship were more frequent among adoptive parents, adoption-related difficulties were rarely reported. Adoptive parents sought professional help more frequently, regardless of parental difficulties. Knowledge-related barriers to seeking help were the most frequent among adoptive parents. Adoption non-specialized help was less satisfactory. Acceptability of psychological parenting interventions was high, but dependent on parental difficulties. Implications for post-adoption services’ development are discussed

Metapopulation Patterns of Iberian Butterflies Revealed by Fuzzy Logic

Metapopulation theory considers that the populations of many species are fragmented into patches connected by the migration of individuals through an interterritorial matrix. We applied fuzzy set theory and environmental favorability (F) functions to reveal the metapopulational structure of the 222 butterfly species in the Iberian Peninsula. We used the sets of contiguous grid cells with high favorability (F ≥ 0.8), to identify the favorable patches for each species. We superimposed the known occurrence data to reveal the occupied and empty favorable patches, as unoccupied patches are functional in a metapopulation dynamics analysis. We analyzed the connectivity between patches of each metapopulation by focusing on the territory of intermediate and low favorability for the species (F < 0.8). The friction that each cell opposes to the passage of individuals was computed as 1‐F. We used the r.cost function of QGIS to calculate the cost of reaching each cell from a favorable patch. The inverse of the cost was computed as connectivity. Only 126 species can be considered to have a metapopulation structure. These metapopulation structures are part of the dark biodiversity of butterflies because their identification is not evident from the observation of the occurrence data but was revealed using favorability functionsFunding for open access charge: Universidad de Málaga / CBU

Evaluation of composite burn index and land surface temperature for assessing soil burn severity in mediterranean fire-prone pine ecosystems

Producción CientíficaWe analysed the relationship between burn severity indicators, from remote sensing and field observations, and soil properties after a wildfire in a fire-prone Mediterranean ecosystem. Our study area was a large wildfire in a Pinus pinaster forest. Burn severity from remote sensing was identified by studying immediate post-fire Land Surface Temperature (LST). We also evaluated burn severity in the field applying the Composite Burn Index (CBI) in a total of 84 plots (30 m diameter). In each plot we evaluated litter consumption, ash colour and char depth as visual indicators. We collected soil samples and pH, soil organic carbon, dry aggregate size distribution (MWD), aggregate stability and water repellency were analysed. A controlled heating of soil was also carried out in the laboratory, with soil from the control plots, to compare with the changes produced in soils affected by different severity levels in the field. Our results shown that changes in soil properties affected by wildfire were only observed in soil aggregation in the high severity situation. The laboratory-controlled heating showed that temperatures of about 300 ◦C result in a significant reduction in soil organic carbon and MWD. Furthermore, soil organic carbon showed a significant decrease when LST values increased. Char depth was the best visual indicator to show changes in soil properties (mainly physical properties) in large fires that occur in Mediterranean pine forests. We conclude that CBI and post-fire LST can be considered good indicators of soil burn severity since both indicate the impact of fire on soil properties.Ministerio de Economía y Competitividad y el Fondo Europeo de Desarrollo Regional (FEDER), en el marco del proyecto GESFIRE (AGL2013-48189-C2-1-R)Junta de Castilla y León en el marco del proyecto SEFIRECYL (LE001P17

Intracellular changes in Ca2 +, K+ and pH after sperm motility activation in the European eel (Anguilla anguilla): Preliminary results

P. 155-158Although it is widely accepted that osmolality and ion fluxes are the main factors triggering sperm motility in fish, a complex universal mechanism for sperm motility activation does not exist in fish, and studies of marine fish species are even more scarce. Therefore, the main goal of this study was to estimate the intracellular variations in the main ions involved in sperm activation for the first time in European eel, in order to provide additional new data about this little-known process. It was observed that levels of intracellular Ca2 + and K+ sperm ions increased significantly 30 s after the hyperosmotic shock compared to baseline levels, and remained at this level until 120 s post-activation. In contrast, the intracellular pH remained constant during the first 30 s, and decreased gradually at 60 and 120 s post-activation. Our data agree with the current main theory for explaining motility activation in marine fish, in which internal fluctuations of Ca2 + and K+ seem to participate in sperm activation. In addition, fluorescent images showed that both Ca2 + and K+ were concentrated in the apical area of the sperm head, which corresponds to the location of the eel sperm mitochondria, suggesting this organelle plays an important role in sperm motility activation.S
