Students today, between Facebook, Google and Metacognition. Ideas to innovate in Higher Education
[ES] En los estudios superiores, al igual que en los demás contextos educativos, no basta con adquirir una serie de conocimientos, es indispensable reflexionar sobre los propios procesos cognitivos para tomar decisiones autónomas y fundamentadas respecto de los aprendizajes. Aprender va mucho más allá de las cuestiones cognitivas, las emociones puestas en juego y las posibilidades de reflexionar respecto de los aprendizajes resultan decisivas en los complejos procesos de construcción de conocimientos. El objetivo del estudio es analizar aspectos metacognitivos vinculados al aprendizaje académico de estudiantes de primer año del Profesorado en Educación Inicial de la Universidad Nacional de RÃo Cuarto y del Instituto Superior MarÃa Inmaculada (Argentina). En la primera parte de la investigación, los estudiantes respondieron a un cuestionario general referido a prácticas y hábitos de estudio y a un inventario de patrones de aprendizaje: ILS (Vermunt, 1998). Luego, se realizaron entrevistas grupales con los estudiantes con el propósito de conocer diferentes puntos de vista respecto de las prácticas de estudio, aprendizaje y enseñanza en la educación superior. Los resultados muestran que la mayorÃa de los participantes requieren de regulaciones externas para desarrollar los procesos de aprendizaje. Se observan ciertas dificultades en la autorregulación de los procesos de lectura, escritura y en el estudio en general. Se propone desarrollar estrategias innovadoras que promuevan en los estudiantes prácticas reflexivas y metacognitivas respecto de los aprendizajes en contextos académicos.[ES] In college, as in other educational
contexts, not enough to acquire a body
of knowledge, it is essential to think
about the cognitive processes to make independent and informed decisions
regarding learning. Learning goes
beyond cognitive issues, emotions and
the posssibilities of think over of learning
are critical in the complex processes of
knowledge construction. The purpose
of the study is to analyze metacognitive
aspects related to academic learning
on first year students of Kindergarten
Teacher at the Universidad Nacional de
RÃo Cuarto and Intituto Superior MarÃa
Inmaculada (Argentina). At the first part
of the research, students answered a
general questionnaire on practices and
habits of study and an inventory of
learning patterns: ILS (Vermunt, 1998).
Then, we conducted group interviews
with students in order to acknowledge
different views regarding the study
practices, learning and teaching in
contexts of higher education. The results
show that most of students require
external regulations to develop learning
processes. We observe some difficulties
in self-regulation of reading processes,
writing and study in general. It is proposed
to develop innovative strategies to
promote thoughtful and metacognitive
practices in students concerning learning
in academic contexts.Elisondo, R.; De La Barrera, ML.; Rigo, DY.; Kowszyk, DI.; Fagotti Kucharski, E.; Ricetti, A.; Siracusa, M. (2016). Estudiantes hoy, entre Facebook, Google y Metacognición.

Homologs of genes and anonymous loci on human Chromosome 13 map to mouse Chromosomes 8 and 14
To enhance the comparative map for human Chromosome (Chr) 13, we identified clones for human genes and anonymous loci that cross-hybridized with their mouse homologs and then used linkage crosses for mapping. Of the clones for four genes and twelve anonymous loci tested, cross-hybridization was found for six, COL4A1, COL4A2, D13S26, D13S35, F10, and PCCA. Strong evidence for homology was found for COL4A1, COL4A2, D13S26, D13S35, and F10, but only circumstantial homology evidence was obtained for PCCA. To genetically map these mouse homologs ( Cf10, Col4a1, Col4a2, D14H13S26, D8H13S35 , and Pcca-rs ), we used interspecific and intersubspecific mapping panels. D14H13S26 and Pcca-rs were located on the distal portion of mouse Chr 14 extending by ∼30 cM the conserved linkage between human Chr 13 and mouse Chr 14, assuming that Pcca-rs is the mouse homolog of PCCA. By contrast, Cf10, Col4a1, Col4a2 , and D8H13S35 mapped near the centromere of mouse Chr 8, defining a new conserved linkage. Finally, we identified either a closely linked sequence related to Col4a2 , or a recombination hot-spot between Col4a1 and Col4a2 that has been conserved in humans and mice.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/47022/1/335_2004_Article_BF00352413.pd
Sugar-and-acid profile of Penjar tomatoes and its evolution during storage
The alcobaca mutation in the Penjar tomato (Solanum lycopersicum L.) variety alters the ripening process and confers a long shelf life (more than four months). Storage of Penjar tomatoes leads to a distinctive sensory profile valued by local consumers, who prefer aged tomatoes to fresh ones. To study chemical changes occurring during storage, we characterized the complete sugar-and-acid profile of 25 accessions at harvest and at 2 and 4 months after harvest. We found considerable variability in the sugar-and-acid profile within the Penjar variety, especially for fructose and glucose. Some accessions presented exceptionally high values for sugars, making them especially interesting for breeding programs. During postharvest, the concentration of glucose, fructose, and citric acid decreased, whereas the concentration of malic and glutamic acids increased. Data from this study offer novel insights into postharvest changes in tomato quality parameters and help elucidate the reasons for the appreciation of this variety by consumers.Postprint (published version
MHC class II-dependent basophil-CD4(+) T cell interactions promote T(H)2 cytokine-dependent immunity
Dendritic cells can prime naive CD4(+) T cells; however, here we demonstrate that dendritic cell-mediated priming was insufficient for the development of T helper type 2 cell-dependent immunity. We identify basophils as a dominant cell population that coexpressed major histocompatibility complex class II and interleukin 4 message after helminth infection. Basophilia was promoted by thymic stromal lymphopoietin, and depletion of basophils impaired immunity to helminth infection. Basophils promoted antigen-specific CD4(+) T cell proliferation and interleukin 4 production in vitro, and transfer of basophils augmented the population expansion of helminth-responsive CD4(+) T cells in vivo. Collectively, our studies suggest that major histocompatibility complex class II-dependent interactions between basophils and CD4(+) T cells promote T helper type 2 cytokine responses and immunity to helminth infectio
