Educación diferenciada por razón de sexo en España: Reflexiones sobre los derechos y libertades educativas desde la perspectiva constitucional y de l…
2021
Gender-separate education, understood as a pedagogical model that provides separate schooling for boys and girls, has been subject to legal and public scrutiny for the past thirty years. Nonetheless, it has not been until 2018 that this educational option was put into the spotlight, especially regarding its constitutionality and compatibility with arts. 1.1, 9.2 and 14 of the Spanish Constitution, which constitute a manifestation of the principles of equality and non-discrimination, while at the same time trying to balance it with art. 27 of said constitutional text, with respect to the right to education and freedom to choose and create educational centers. Against this backdrop, the prese…
Consum de drogues en dones víctimes d’explotació sexual
2018
espanolEsta investigacion plantea como objetivo principal aproximarse a la problematica de las mujeres victimas de trata con finalidades de explotacion sexual, en relacion al consumo de drogas, mediante un metodo de analisis cualitativo. A partir de una entrevista semiestructurada de eleaboracion propia, se recoje la informacion de una muestra de 13 mujeres que se encuentran albergadas en la Fundacion de Solidaritat Amaranta de Granada y Valencia. Los resultados muestran que hay un consumo puntual de drogas en las mujeres de la muestra, pero con unos matices muy concretos. Se trata de un consumo impuesto por los miembros de la Red de Trata o como forma de soportar la explotacion. EnglishThi…
Violación de la prohibición de discriminación en el tratamiento de la prostitución por parte de los tribunales laborales españoles
2020
El reconocimiento pleno de derechos laborales a toda manifestación del trabajo sexual, incluida la prostitución, resulta plenamente necesario para la tutela no discriminatoria de las personas que, por necesidades económicas, decida ejercer libremente la prostitución. Los tribunales laborales españoles no responden, en este punto, a la lógica tuitiva del derecho del trabajo e ignoran la vulnerabilidad a la que dejan expuesta a las trabajadoras sexuales. Aplican para ello criterios que no siempre son estrictamente jurídicos, efectuando conclusiones voluntaristas que predeterminan el contenido de sus fallos sin tomar en consideración el derecho. Se produce como consecuencia de ello una discrim…
High-Performance PCR for Alleles Discrimination of Chromo-Helicase-DNA Binding Protein (CHD1) Gene in Bird Sexing
2023
Genetic analyses aiming at assessing the presence of specific sequences or alleles are often carried out by PCR. Sexing of most birds is nowadays based on PCR with “universal” primers and relies on the assessment of the presence of the sex-linked CHD1-Z and -W alleles. The entire workflow is relatively time-consuming, especially for batch analyses, whereas methods that allow carrying out the entire procedure in a short time are highly desirable. The only method for outdoor analyses reported so far relies on LAMP; however; it fails to work properly in Procellariiformes. Besides improving the LAMP test; we have developed a PCR-based DNA amplification procedure (named high-performance PCR); wh…
Non-Invasive Sex Determination of Nestlings and Adult Bonelli’s Eagles Using Morphometrics
2023
Biometric analysis allows the sexing of most vertebrates, particularly birds. Birds of prey, and, especially, the Bonelli’s eagle (Aquila fasciata), show reverse sexual dimorphism (i.e., females are usually larger than males). In contrast to blood sampling, the use of morphometrics allows sex determination using a non-invasive method, and, therefore, it facilitates fieldwork. By means of a linear discriminant analysis of biometric variables, we obtained different equations that allow the sexing of nestlings and adult Bonelli’s eagles. We sampled 137 Bonelli’s eagles, 82 nestlings and 55 adults in eastern Spain during the period 2015–2022. The sexes obtained after lin…
RAD SNP markers as a tool for conservation of dolphinfish Coryphaena hippurus in the Mediterranean Sea: Identification of subtle genetic structure an…
2016
Dolphinfish is an important fish species for both commercial and sport fishing, but so far limited information is available on genetic variability and pattern of differentiation of dolphinfish populations in the Mediterranean basin. Recently developed techniques allow genome-wide identification of genetic markers for better understanding of population structure in species with limited genome information. Using restriction-site associated DNA analysis we successfully genotyped 140 individuals of dolphinfish from eight locations in the Mediterranean Sea at 3324 SNP loci. We identified 311 sex-related loci that were used to assess sex-ratio in dolphinfish populations. In addition, we identifie…
Sex difference in the interaction of alcohol intake, hepatitis B virus, and hepatitis C virus on the risk of cirrhosis
2017
Background The joint effect of the interaction of alcohol intake, hepatitis B virus (HBV) and hepatitis C virus (HCV) on the risk of cirrhosis is still unexplored because a large sample size is required for this investigation. Objective Evaluation of interaction of HBV, HCV and alcohol abuse on the risk of cirrhosis. Design We analysed 12,262 consecutive patients with chronic liver disease of various aetiologies referring to 95 Italian liver units in 2001 or 2014. To evaluate the interaction between alcohol abuse, HBV infection, and HCV infection, patients unexposed to either factors were used as reference category. Adjustment for BMI and age was done by multiple logistic regression analysi…
The evolution of dosage-compensation mechanisms
2000
Dosage compensation is the process by which the expression levels of sex-linked genes are altered in one sex to offset a difference in sex-chromosome number between females and males of a heterogametic species. Degeneration of a sex-limited chromosome to produce heterogamety is a common, perhaps unavoidable, feature of sex-chromosome evolution. Selective pressure to equalize sex-linked gene expression in the two sexes accompanies degeneration, thereby driving the evolution of dosage-compensation mechanisms. Studies of model species indicate that what appear to be very different mechanisms have evolved in different lineages: the male X chromosome is hypertranscribed in drosophilid flies, bot…
Male Investments in High Quality Sperm Improve Fertilization Success, but May Have Negative Impact on Offspring Fitness in Whitefish.
2015
Many ejaculate traits show remarkable variation in relation to male social status. Males in disfavoured (subordinate) mating positions often invest heavily on sperm motility but may have less available resources on traits (e.g., secondary sexual ornaments) that improve the probability of gaining matings. Although higher investments in sperm motility can increase the relative fertilization success of subordinate males, it is unclear whether status-dependent differences in sperm traits could have any consequences for offspring fitness. We tested this possibility in whitefish (Coregonus lavaretus L.) by experimentally fertilizing the eggs of 24 females with the sperm of either highly-ornamente…
