Traditional festivities, political domination and social reproduction: Case analysis of Valencia’s Fallas
2020
The traditional festivities have been usually analysed in social sciences as a mode of generating sociability and social cohesion, not only in traditional societies but also in modern ones. However...
Infertility-related stress, anxiety and ovarian stimulation: can couples be reassured about the effects of psychological factors on biological respon…
2016
Abstract The aim of this prospective, longitudinal study was to examine the association between couples' pre-treatment psychological characteristics (state anxiety and infertility-related stress levels of both partners) and ovarian response during assisted reproductive technology treatment in a well-controlled sample. A total of 217 heterosexual couples (434 patients), suffering from primary infertility and undergoing their first assisted reproductive technology treatment at the Reproductive Medicine Unit of ANDROS Day Surgery Clinic in Palermo (Italy), were recruited. Psychological variables were assessed using the State Scale of State-Trait Anxiety Inventory (STAI-S) and the Fertility Pro…
Las tecnologías de reproducción asistida y sus metáforas
2005
The enormous development -in both research and application- of assisted reproduction technologies has been accompanied by a lack of theoretical reflection on its power of change: the concept and treatment of the body, the concept of paternity or motherhood, etc.The metaphorical analysis allows us to deconstruct both dominant discourses: patriarchal and reductionist biomedical. We propose a transdisciplinary analysis which explains the interactions between the diverse discourses: biomedical, mass media, legal, symbolicpsycho-social, gender, historic- which make up the supply as well as the creation of demand of all these practices. The transdisciplinary analysis would help to reveal the biom…
¿La "reina de la fiesta"? Fiestas tradicionales y reproducción de la desigualdad de género. El caso de las Fallas de València
2020
Las desigualdades de género en las fiestas tradicionales han generado una creciente atención social y académica. Fenómenos como el acoso, abuso o agresiones sexuales, los roles segregados o las codificaciones patriarcales que facilitan instituciones festivas muy masculinizadas, tanto en las composiciones como en las dinámicas internas, han revelado que existe una persistencia en el mantenimiento que choca con la evolución de la sociedad hacia una mayor igualdad. En este sentido entendemos que la cultura festiva tradicional no puede interpretarse correctamente desde la dimensión del consenso sino como una arena de conflicto social. En esta perspectiva la idea del ritual festivo como generado…
Un-rooted grafted cuttings for eggplant plug-transplant production and shipping: simulated transportation and healing requirements
2019
Vegetable grafting is one of the most effective eco-friendly techniques to overcome pests and soilborne diseases in modern cropping systems of fruiting vegetables. Due to the increased farmers’ preference for grafted seedlings of high quality and better performance, the use of vegetable grafted plants is rapidly spreading and expanding over the world and intensive researches on new commercial production systems are under way. However, in many areas of the world, due to the high cost of skilled manpower, the use of grafted plug plants is still limited causing a relatively slow development of the grafting nursery industry. The aim of this work was to evaluate a possible use of un-rooted graft…
Study of the Evolutionary Relationships among Limonium Species (Plumbaginaceae) Using Nuclear and Cytoplasmic Molecular Markers
2000
The genus Limonium, due to the patchiness of the natural habitats of its species as well as the high frequency of hybridization and polyploidy and the possibility of reproduction by apomixis, provides an example of all the principal mechanisms of rapid speciation of plants. As an initial study of evolution in this genus, we have analyzed intra- and interspecific variability in 17 species from section Limonium, the largest in the genus, based on RFLPs of cpDNA and nuclear rDNA ITS sequences. In the cpDNA analysis, 21 restriction enzymes were used, resulting in 779 fragments, 490 of which were variable and 339 parsimony informative. L. furfuraceum exhibited two relatively divergent cpDNA hapl…
Impact of polyploidy on fertility variation of Mediterranean Arundo L. (Poaceae)
2015
International audience; Failure of seed production in the genus Arundo L. (Poaceae) is often attributed to polyploidy. This study tested the impact of two ploidy levels (2n = 12 and 18x) on the fertility of four Mediterranean Arundo. Viable pollen was screened from its production to its germination, and seed occurrence was monitored in admixture or isolated conditions. In addition, insights on restructuration of polyploid genornes were analysed using molecular cytogenetics. Our results show that high ploidy levels do not automatically induce failure of sexual reproduction. The two ploidy levels are able to produce viable pollen and seed set depending on species and cultural conditions. The …
Are Sick Individuals Weak Competitors? Competitive Ability of Snails Parasitized by a Gigantism-Inducing Trematode
2013
Parasitized individuals are often expected to be poor competitors because they are weakened by infections. Many trematode species, however, although extensively exploiting their mollusc hosts, also induce gigantism (increased host size) by diverting host resources towards growth instead of reproduction. In such systems, alternatively to reduced competitive ability due to negative effects of parasitism on host performance, larger size could allow more efficient resource acquisition and thus increase the relative competitive ability of host individuals. We addressed this hypothesis by testing the effect of a trematode parasite Diplostomum pseudospathaceum on the competitive ability of its sna…
Colonisation process of vegetative fragments of Posidonia oceanica (L.) Delile on rubble mounds
2005
Seagrass colonise new areas via the dispersion of seeds or vegetative fragments. Independent of the manner of colonization, habitat requirements need to be met for the successful establishment of seagrasses. Here we report on the colonization process of Posidonia oceanica in a highly disturbed area: a gas pipeline trench at Capo Feto (SW Sicily, Italy). A trench dredged through a P. oceanica bed was back-filled with rubble added from dump barges leading to the formation of a series of rubble mounds on the seabed. Over time, these mounds became colonised with P. oceanica. In order to understand the pattern of P. oceanica colonization, shoot density was quantified over 3 years (2001-2003) on …
El hipotético derecho a la reproducción
2011
RESUMENEsta comunicación analiza porqué no existe en nuestro ordenamiento ningún derecho a la maternidad o derecho a la paternidad, y cómo cuesta llegar a un consenso sobre si nuestro ordenamiento jurídico protege los derechos sexuales y reproductivos, y si lo hace, cuál es el contenido de estos derechos. Este análisis se contrasta con el debate doctrinal que si se ha producido sobre la existencia de un hipotético derecho a la reproducción, una autonomía procreativa en positivo, y la correspondiente discusión sobre su respaldo en nuestro actual ordenamiento jurídico. Debate que no se aplica en los mismos términos cuando se trata de la autonomía reproductiva en negativo, por ejemplo, en el c…
