Profile of female students of engineering universities in Mexico and Spain
Gender studies in higher education have emerged in parallel to reflections and rising feminist movement. The main objectives of academic feminism are related to women's visibility improvement as well as soft skills developers’ roles. But a gap in TECH studies can be detected. Women studies in higher education are mostly related to life and social sciences, behavioral, journalism and information, business and management and law, in contrast to engineering, architecture, manufacturing, construction, ICT or any kind of TECH studies. Thus, the main objective of this work is related to survey design in order to develop a qualitative research to inquire about TECH higher education, female population profile, both at UdG-CUALTOS (Guadalajara, Mexico) and UPC (Barcelona, Spain).This profile can provide some influent identity elements, related to perceptions and expectations of women-TECH, deemed appropriate from their professions as engineers. From these results, it should be possible to draw gender alternatives for future generations in TECH environmentsPostprint (published version
Courtship plasticity reveals the evolution of dialects in allopatric fish populations
Traditionally, reproductive isolation between disjoint populations has been thought to emerge as a result of the accumulation of different mutations, genetic drift, or through the effects of natural and sexual selection^1^. Alternatively, the ability of an organism to express different phenotypes depending on the environment (i.e. phenotypic plasticity) could produce reproductive isolation^2,3^. Sexually selected traits are expected to be phenotypically plastic and can result in modifications of the species recognition system and thus originate new species^4^. Here we show that the population-characteristic male courtship behaviour of a fish (Girardinichthys multiradiatus) is modified in the presence of females from other populations, that this is due to the males responding to subtle cues from females, and that they fail to emulate the female's population-characteristic behaviour. We conclude that plasticity has led to the creation of local dialects in the courtship pattern that hampers communication between heterogametic individuals and promotes pre-mating isolation
Preparing relative and near kin caregivers : evaluation of ROOTS
Family and Children’s Services at the Monterey County Department of Social and Employment Services, MCDSES, strive for children’s stability and safety. In Monterey County, there are too many unsuccessful relative and near kin placements. Relatives and near kin caregivers are mandated to complete ROOTS training, Relative Offering Ongoing Ties and Support. ROOTS\u27 curriculum intends to increase caregiver\u27s knowledge to prepare and guide them in becoming a stable home for a child in need. The evaluation of ROOTS, a knowledge based pre/posttest, demonstrated the caregivers\u27 appreciation of support and it gave a broad understanding of the knowledge gained by the caregivers
Constraining New Physics with D meson decays
Latest Lattice results on form factors evaluation from first principles
show that the standard model (SM) branching ratios prediction for the leptonic
decays and the semileptonic SM branching ratios of the
and meson decays are in good agreement with the world average
experimental measurements. It is possible to disprove New Physics hypothesis or
find bounds over several models beyond the SM. Using the observed leptonic and
semileptonic branching ratios for the D meson decays, we performed a combined
analysis to constrain non standard interactions which mediate the transition. This is done either by a model independent way through
the corresponding Wilson coefficients or in a model dependent way by finding
the respective bounds over the relevant parameters for some models beyond the
standard model. In particular, we obtain bounds for the Two Higgs Doublet Model
Type-II and Type III, the Left-Right model, the Minimal Supersymmetric Standard
Model with explicit R-Parity violation and Leptoquarks. Finally, we estimate
the transverse polarization of the lepton in the decay and we found it
can be as high as .Comment: 28 pages, 8 figures, 3 tables. Improved and extended analysis with

A new strategy for probing the Majorana neutrino CP violating phases and masses
We propose a new strategy for detecting the CP-violating phases and the
effective mass of muon Majorana neutrinos by measuring observables associated
with neutrino-antineutrino oscillations in decays. Within the
generic framework of quantum field theory, we compute the non-factorizable
probability for producing a pair of same-charged muons in decays as
a distinctive signature of oscillations. We show
that an intense neutrino beam through a long baseline experiment is favored for
probing the Majorana phases. Using the neutrino-antineutrino oscillation
probability reported by MINOS collaboration, a new stringent bound on the
effective muon-neutrino mass is derived.Comment: 4 pages, 1 figur
Scattering processes could distinguish Majorana from Dirac neutrinos
It is well known that Majorana neutrinos have a pure axial neutral current
interaction while Dirac neutrinos have the standard vector-axial interaction.
In spite of this crucial difference, usually Dirac neutrino processes differ
from Majorana processes by a term proportional to the neutrino mass, resulting
in almost unmeasurable observations of this difference. In the present work we
show that once the neutrino polarization evolution is considered, there are
clear differences between Dirac and Majorana scattering on electrons. The
change of polarization can be achieved in astrophysical environments with
strong magnetic fields. Furthermore, we show that in the case of unpolarized
neutrino scattering onto polarized electrons, this difference can be relevant
even for large values of the neutrino energy.Comment: 12 pages, 5 figure
