Age influence in gender stereotypes related to Internet use in young people

[EN]The existence of gender stereotypes in relation to the use of the Internet led to the need to carry out the present study, which approaches young people perception of the use of the Internet and technologies. Based on knowledge of the existence of gender stereotypes in relation to the use of the Internet, the objective of the study is to detect whether the age of young people, with some previous experience on the Internet, marks differences in relation to the use they make of the Internet; in other words, whether the use made of the world network and the existing stereotypes may or may not have some type of dependent relationship with the age of the subjects. The study was applied in a group of the University of Salamanca (Spain) during the academic year 2018/2019, after the previous realization of activities during four months of sensitization, under the European project WYRED (netWorked Youth Research for Empowerment in the Digital). The final sample was composed by 48 subjects. For this purpose, a questionnaire was applied with 40 final items, which collected different activities that can be carried out on the Internet in order to find out what trend of use they presented in relation to the Internet, in comparison to their age. The two groups consisted of 26 people aged 20 or younger, and 22 people aged 20 or older. By means of a descriptive analysis, and the application of normality tests and non-parametric tests, no dependent relationships were detected between the use of the Internet after carrying out the survey and the age group in which the subject belonged. For the future it would be of special interest to be able to repeat the study comparing the opinion and use of young people on the Interne

Pilot study on university students' opinion about STEM studies at higher education

The percentages of women enrolled in higher education in the STEM sector are significantly lower than those of men. Overall, gender representation in science, technology, engineering and mathematics degrees in Europe is not balanced. The Leaky Pipeline phenomenon, marked by gender stereotypes, makes the latent gender gap a relevant topic of study. Studies exist on academic performance, self-perception, self-efficacy, outcome expectations; however, studying gender stereotypes linked to STEM studies is also essential. It is necessary to know the social and family context in which young people have grown up, as well as their perception of such studies. To study gender stereotypes of university students about STEM studies, a questionnaire has been designed for empirical validation. For the design of the instrument, to be validated, items from other instruments have been taken and adapted to Spanish. After the design of the instrument, an online pilot study has been applied in the University of Salamanca, the University of Valencia and the Polytechnic University of Valencia. A total of 115 people answered the questionnaire. The results of the pilot study reveal that the study sample is not particularly marked by gender stereotypes about gender equality in STEM. Also, the sample is receptive to learning about science and applying it in their lives. On the other hand, the idea that women have to give up their studies and careers to look after their families and children is rejected. The idea that men are more interested in university studies than women is also rejected. At the same time, the sample is aware of the difficulties that women encounter in the STEM sector. Another optimistic point of the results is that there are no alarming data on bad experiences due to gender. In the future, the study will be replicated on a larger scale

New constraints on protostellar jet collimation from high-density gas UV tracers

The analysis of high-resolution profiles of the semiforbidden UV lines of C III](1908) and Si III](1892) in the spectra of T Tauri stars (TTSs) shows the following : (1) There is C III](1908) and Si III](1892) emission at velocities that are similar to those observed in the optical forbidden lines formed in the TTSs jets. The luminosity of the UV lines is comparable to that of the optical lines. (2) The comparison between the optical and UV light curves indicates that the C III](1908) and Si III](1892) emission of RY Tau is not associated with accretion shocks, but it is produced farther than 2 R-* from the star. (3) The profiles of the UV semiforbidden lines are significantly broader than those of the optical forbidden lines. These profiles cannot be produced in a narrow collimated beam, and they are most likely produced in a bow-shaped shock wave formed at the base of the optical jet, where the hot gas emits in a broad range of projected radial velocities. (4) The atmosphere of RU Lup contributes significantly to the Si III](1892) emission. (5) A puzzling narrow feature is observed close to the C III](1908) line. The feature is blueshifted by -260 km s(-1), which corresponds to the wind terminal velocity measured in the P Cygni profile of the Mg II (UV1) lines. Moreover, constraints are derived on the characteristics of the C III](1908) and Si III](1892) emitting region in RY Tau. It is shown that 4.7 less than or equal to log T-e less than or equal to 5.0 and 10(9) cm(-3) less than or equal to N-e less than or equal to 10(11) cm(-3) provided that the emission is produced in a collisional plasma and that the 1665 Angstrom feature observed in low-dispersion International Ultraviolet Explorer (IUE) spectra is confirmed to be O III](1665) emission produced in the wind. These very high densities are difficult to generate in the shocks produced by the magnetic pinching of centrifugally driven magnetized disk winds. The data also suggest that the shocked layer has a radius of some few stellar radii and it is closer than similar to 38 R-* to the star

Estudio piloto sobre la percepción de la brecha de género en estudios de ingeniería informática

La brecha de género es uno de los principales problemas presentes en la sociedad actual. La igualdad, no solo de la mujer, sino de las diferentes identidades de género, forma parte de las prioridades de la Unión Europea, así como de gran parte de los países desarrollados. En particular, en las áreas de ciencias, tecnología, ingeniería y matemáticas (STEM), la brecha de género es claramente visible tanto en el ámbito académico como en el profesional. En educación superior, de acuerdo con un estudio a nivel mundial, tan solo el 35% de todos los estudiantes matriculados en estudios STEM son mujeres. Existen un gran número de iniciativas que trabajan en reducir la brecha de género en diversos contextos, desde educación infantil y primaria, hasta el ámbito empresarial. El presente trabajo presenta un estudio piloto que permite validar el cuestionario GENCE definido en trabajos previos. Concretamente, se ha aplicado en el Grado de Ingeniería Informática de la Universidad de Salamanca con el fin de conocer la percepción de sus estudiantes en relación con la brecha de género tras aplicar un conjunto de acciones para fomentar la diversidad en el ámbito de la ingeniería

Role of the Cellular Prion Protein in Oligodendrocyte Precursor Cell Proliferation and Differentiation in the Developing and Adult Mouse CNS

There are numerous studies describing the signaling mechanisms that mediate oligodendrocyte precursor cell (OPC) proliferation and differentiation, although the contribution of the cellular prion protein (PrPc) to this process remains unclear. PrPc is a glycosyl-phosphatidylinositol (GPI)-anchored glycoprotein involved in diverse cellular processes during the development and maturation of the mammalian central nervous system (CNS). Here we describe how PrPc influences oligodendrocyte proliferation in the developing and adult CNS. OPCs that lack PrPc proliferate more vigorously at the expense of a delay in differentiation, which correlates with changes in the expression of oligodendrocyte lineage markers. In addition, numerous NG2-positive cells were observed in cortical regions of adult PrPc knockout mice, although no significant changes in myelination can be seen, probably due to the death of surplus cells

Abnormal accumulation of autophagic vesicles correlates with axonal and synaptic pathology in young Alzheimer’s mice hippocampus

Dystrophic neurites associated with amyloid plaques precede neuronal death and manifest early in Alzheimer’s disease (AD). In this work we have characterized the plaque-associated neuritic pathology in the hippocampus of young (4- to 6-month-old) PS1M146L/APP751SL mice model, as the initial degenerative process underlying functional disturbance prior to neuronal loss. Neuritic plaques accounted for almost all fibrillar deposits and an axonal origin of the dystrophies was demonstrated. The early induction of autophagy pathology was evidenced by increased protein levels of the autophagosome marker LC3 that was localized in the axonal dystrophies, and by electron microscopic identification of numerous autophagic vesicles filling and causing the axonal swellings. Early neuritic cytoskeletal defects determined by the presence of phosphorylated tau (AT8-positive) and actin–cofilin rods along with decreased levels of kinesin-1 and dynein motor proteins could be responsible for this extensive vesicle accumulation within dystrophic neurites. Although microsomal Aβ oligomers were identified, the presence of A11-immunopositive Aβ plaques also suggested a direct role of plaque-associated Aβ oligomers in defective axonal transport and disease progression. Most importantly, presynaptic terminals morphologically disrupted by abnormal autophagic vesicle buildup were identified ultrastructurally and further supported by synaptosome isolation. Finally, these early abnormalities in axonal and presynaptic structures might represent the morphological substrate of hippocampal dysfunction preceding synaptic and neuronal loss and could significantly contribute to AD pathology in the preclinical stages
