Comunicación, sentido y vida cotidiana

La pregunta por la vida cotidiana, su estructura, su funcionamiento, no es una novedad en el ámbito de las ciencias sociales. Se han ocupado de esta problemática pensadores de la talla de Heller, Habermas, Goffman, Freiré, Wolf, por citar sólo algunos. Diferentes enfoques, teorías y preocupaciones han derivado en un vasto campo de estudio que observa y rescata lo que era considerado como "materiales secundarios", indagando cómo los pequeñísimos actos cotidianos realzan temas muy importantes (Wolf, 1979). En el campo de la comunicación cobran fuerza en cantidad y calidad, a partir de 1980 (Fuentes, 1991) los estudios que abordan diferentes aspectos de la cotidianidad para indagar por ejemplo, en un cambio de perspectiva, no ya lo que los medios hacen a la gente, sino lo que la gente hace con y a partir de los medios, haciendo aparecer en primer plano al actor de la comunicación.ITESO, A.C

Biodrying under Greenhouse Conditions as Pretreatment for Horticultural Waste

The biodrying process was studied as an alternative technology to reduce the mass and volume of horticultural waste. Four static piles were prepared inside a greenhouse: two containing whole waste and two consisting of shredded waste. All the piles were compared with a test pile containing whole waste and placed outside the greenhouse. In two cases, ventilation ducts were installed to improve aeration. Each greenhouse was 2.0 m wide, 3.5 m long and 1.16 m high. The air temperature and relative humidity were monitored both inside and outside the greenhouse. Mass, humidity, organic matter and total nitrogen in the waste were measured. Piles inside the greenhouse showed decreases of 80% and 75% in weight and volume, respectively, during the first 16 days. The data obtained in this work suggest that biodrying could improve the handling and transport of horticultural waste while also minimizing the impact of pollutants

La significación del ejido

Indagación semiótica de la práctica social de un campesino ejidatario de Cuquío, Jalisco, con la que se pretende hacer explícita la manera en cómo se construye la significación en un discurso que habla de la realidad del ejido. El discurso analizado fue resultado de una entrevista personal realizada a un campesino. En el análisis se develan las significaciones latentes de su ideología y su utopía; por ejemplo, a través del estudio de los programas narrativos se reconocen las marcas ideológicas de la ‘pasividad’ junto con las marcas utópicas del ‘cambio social’. Se incluye obra fotográfica de Carolina Ramírez, reproducida en blanco y negro.ITESO, A.C

La fauna del pleistoceno inferior de la sierra de Quibas (Abanilla, Murcia)

El yacimiento kárstico cuaternario de la Sierra de Quibas (Abanilla, Murcia) ha proporcionado una amplia lista faunística constituida por 53 especies repartidas entre gasterópodos, miriápodos, anfibios, reptiles, aves y mamíferos. En el conjunto de los gasterópodos destaca Palaeoglandina, un género que se extingue en el resto de Europa durante el Plioceno y que se mantiene como relicto en el Pleistoceno de la Península Ibérica. Dos de las especies de aves determinadas, Gypaetus barbatus y Gerontieus eremita, y una de las serpientes, Elaphe cf. E. sealaris, apenas se hallan representadas en el registro fósil. Hay además varias especies de aves cuya aparición en Quibas supone la primera cita en el Pleistoceno inferior de la Península Ibérica. Entre los mamíferos posee una especial relevancia la presencia del cercopitécido Macaca sylvanus. La asociación de los taxones Arvieola deuealíon, Castillomys rivas rivas, Elíomys intermedius, Equus altidens y Capra sp. aff. C. alba permite la correlación con Plines 1, Orce 3 y Venta Micena, entre otros. El yacimiento de Quibas puede situarse, por tanto, antes del final del Pleistoceno inferior, con una antigüedad entre 1.3 y 1 Ma. Por lo que se refiere a las condiciones paleoclimáticas, podemos inferir a partir de la asociación faunística un régimen xerófilo, muy semejante al actual en el área geográfica, aunque quizás con valores de humedad y temperatura algo superiores. El entorno de la cavidad kárstica estaba formado por roquedo calcáreo con áreas abiertas de matorral, pero en las proximidades se desarrollaron humedales y zonas arboladas, como así lo atestigua la presencia de aves y micromamíferos típicos de estos hábitats.The Quaternary karstic site of Sierra de Quibas (Abanilla, Murcia, Spain) has provided a wide faunallist with 53 species distributed among gastropods, myriapods, amphibians, reptiles, birds and mammals. Especially interesting among the gastropods is Palaeoglandina that became extinct in Europe during the Pliocene. It remains as a relict genus in the Pleistocene of the Iberian Peninsula. Two of the birds, Gypaetus barbatus and Geronticus eremita, and a snake, Elaphe cf. E. sealaris, are scarcely represented in the fossil record. For several birds, it is the first record in the Lower Pleistocene of the Iberian Peninsula. Among the mammals, the presence of the Cercopithecine Macaca sylvanus is especially relevant. The assemblage of the taxa Arvicola deucalion, Castillomys rivas rivas, Eliomys intermedius, Equus altidens and Capra sp. aff. C. alba allows the correlation with Plines 1, Orce 3 and Venta Micena, among other sites. Therefore Quibas can be clated before the end of Lower Pleistocene, between 1.3 and 1 Ma. A dry paleoclimatic regime, very similar to the current climate in the geographical area, though perhaps slightly wetter and warmer, can be inferred from the faunal assemblage. The environment of the karstic cavity was a rocky place with open brushwood areas, but in the proximities there were wetlands and woodlands, as can be inferred from the presence of birds and micromammals characteristic of these [email protected] [email protected]

Phosphomannomutase deficiency (PMM2-CDG): Ataxia and cerebellar assessment

Background: Phosphomannomutase deficiency (PMM2-CDG) is the most frequent congenital disorder of glycosylation. The cerebellum is nearly always affected in PMM2-CDG patients, a cerebellar atrophy progression is observed, and cerebellar dysfunction is their main daily functional limitation. Different therapeutic agents are under development, and clinical evaluation of drug candidates will require a standardized score of cerebellar dysfunction. We aim to assess the validity of the International Cooperative Ataxia Rating Scale (ICARS) in children and adolescents with genetically confirmed PMM2-CDG deficiency. We compare ICARS results with the Nijmegen Pediatric CDG Rating Scale (NPCRS), neuroimaging, intelligence quotient (IQ) and molecular data. Methods: Our observational study included 13 PMM2-CDG patients and 21 control subjects. Ethical permissions and informed consents were obtained. Three independent child neurologists rated PMM2-CDG patients and control subjects using the ICARS. A single clinician administered the NPCRS. All patients underwent brain MRI, and the relative diameter of the midsagittal vermis was measured. Psychometric evaluations were available in six patients. The Mann-Whitney U test was used to compare ICARS between patients and controls. To evaluate inter-observer agreement in patients' ICARS ratings, intraclass correlation coefficients (ICC) were calculated. ICARS internal consistency was evaluated using Cronbach's alpha. Spearman's rank correlation coefficient test was used to correlate ICARS with NPCRS, midsagittal vermis relative diameter and IQ. Results: ICARS and ICARS subscores differed between patients and controls (p < 0.001). Interobserver agreement of ICARS was "almost perfect" (ICC = 0.99), with a "good" internal reliability (Cronbach's alpha = 0.72). ICARS was significantly correlated with the total NPCRS score (rs 0.90, p < 0.001). However, there was no agreement regarding categories of severity. Regarding neuroimaging, inverse correlations between ICARS and midsagittal vermis relative diameter (rs -0.85, p = 0.003) and IQ (rs -0.94, p = 0.005) were found. Patients bearing p.E93A, p.C241S or p.R162W mutations presented a milder phenotype. Conclusions: ICARS is a reliable instrument for assessment of PMM2-CDG patients, without significant inter-rater variability. Despite our limited sample size, the results show a good correlation between functional cerebellar assessment, IQ and neuroimagingFor the first a correlation between ICARS, neuroimaging and IQ in PMM2-CDG patients has been demonstratedThe work was supported by national grants PI14/00021, PI11/01096, PI11/01250, and PI10/00455 from the National Plan on I+D+I, cofinanced by ISC-III (Subdirección General de Evaluación y Fomento de la Investigación Sanitaria) and FEDER (Fondo Europeo de Desarrollo Regional) and IPT-2012- 0561-010000 from MINECO.

Heritage and minority languages, and their learning: A general bibliometric approach and content analysis

This research was supported by the R&D project ‘LEyLA’ (Ref. PID2021-123055NB-I00) funded by MCIN/AEI/10.13039/501100011033 and by ‘ERDF A way of making Europe’The cultural and linguistic diversity that characterises our current society has led to different ways of considering languages and their status in their respective communities of use. Nowadays, not only the dominant language prevails, but other languages that characterise any social group are also increasingly taken into account, and there are studies on how they can influence the learning of the set of languages that a person uses in his or her context, and even in the teaching and learning process in general. Among these languages that represent the identity of that individual, we can find those of heritage. This paper represents the first bibliometric study on heritage and minority languages, and their connection with learning. The study period spans from the first paper published in 1989 until today, using SciMAT, software developed for longitudinal scientific mapping analysis, so this research contributes to reduce the existing gap in the scientific literature, and offers a starting point for the study of this topic. As much as 1341 research publications from the Web of Science dealing with this issue were processed and analysed. Following a bibliometric analysis, as well as the thematic and conceptual evolution of these publications, the results show a growing scientific interest in the topic from 2018, with the USA being the country with the highest production. Research was mainly carried out at universities, and the predominant research areas are Linguistics, Education and Psychology. Likewise, among the most productive authors, Silvina Montrul stands out. Finally, the main topics of interest for the scientific community are bilingualism and multilingualism, followed by maintenance of heritage languages and their speakers.MCIN/AEI/10.13039/501100011033 PID2021-123055NB-I00‘ERDF A way of making Europe
