Il ladino e i suoi idiomi

2020

In questo capitolo si illustrano le suddivisioni interne al gruppo ladino. Dopo aver sottolineato la posizione particolare dell’ampezzano (appartenente linguisticamente al gruppo cadorino), si mostra che le restanti varietà sono separate da tre diverse linee di demarcazione che si sovrappongono: una linea di origine altomedievale che corre da nord a sud, dividendo Fassa e Gardena da Badia e Fodom; una da ovest a est, più recente, che isola il ladino settentrionale (valli di Gardena e Badia) dal ladino meridionale; e infine una linea circolare che separa le varietà centrali da quelle periferiche.Nella seconda parte del capitolo sono discusse le differenze fonologiche, morfologiche, sintattic…

BOUNDARIES OF AGENT AND EXPERIENCER IN LATVIANSummaryThe deep sentence structure is reflected in the surface sentence structure. There is no doubt that the actor is an important participant in the semantics of the sentence, and the patient is important in the transitive verb argument structure. Other participant roles form periphery of the situation.The article deals with the issue of boundaries between agent and experiencer roles. In Latvian, both agent and experiencer employ the same means of expression – both participants syntactically can be expressed by the subject. The aim of this article is to clarify whether it is easy to divide these participant roles and what criteria help to make…

Hachetetepé : revista científica de educación y comunicación

2021

Siempre han existido estereotipos que condicionan la manera en que los individuos ven y entienden la realidad. Estas construcciones imaginarias resultan fundamentales en el proceso de socialización y se adquieren en gran parte a través de lecturas de la infancia. El porcentaje de traducciones en relación con las publicaciones totales de TRALIJ en España se ha venido situando en torno al 40 %1 en los últimos años, lo que pone de manifiesto el peso de la traducción de este tipo de literatura a la hora de perpetuar o rechazar los modelos de masculinidad y feminidad a los que exponemos a los más pequeños. Este es un análisis empírico-descriptivo de las traducciones al castellano y valenciano de…

Nitropyrroles, Diels-Alder reactions assisted by microwave irradiation and solvent effect. An experimental and theoretical study

2017

The behaviors of N-tosylnitropyrroles acting as electrophilic dienophiles in polar Diels-Alder reactions joint to different dienes of increeased nucleophilicity are analyzed. The reactions were developed under microwave irradiation using toluene or protic ionic liquids (PILs) as solvents and in free solvent conditions. In all the cases explored we observed good yields in short reaction times. For these reactions, the free solvent condition and the use of protic ionic liquids as solvents offer similar results. However, the free solvent conditions favor environmental sustainability. The role of PILs in these polar Diels-Alder reactions has been theoretically studied within the Molecular Elect…

Evolution of male and female choice in polyandrous systems

2017

We study the evolution of male and female mating strategies and mate choice for female fecundity and male fertilization ability in a system where both sexes can mate with multiple partners, and where there is variation in individual quality (i.e. in the availability of resources individuals can allocate to matings, mate choice and production of gametes). We find that when the cost of mating differs between sexes, the sex with higher cost of mating is reluctant to accept matings and is often also choosy, while the other sex accepts all matings. With equal mating costs, the evolution of mating strategies depends on the strength of female sperm limitation, so that when sperm limitation is stro…

Coevolution of parental investment and sexually selected traits drives sex-role divergence

2016

Sex-role evolution theory attempts to explain the origin and direction of male–female differences. A fundamental question is why anisogamy, the difference in gamete size that defines the sexes, has repeatedly led to large differences in subsequent parental care. Here we construct models to confirm predictions that individuals benefit less from caring when they face stronger sexual selection and/or lower certainty of parentage. However, we overturn the widely cited claim that a negative feedback between the operational sex ratio and the opportunity cost of care selects for egalitarian sex roles. We further argue that our model does not predict any effect of the adult sex ratio (ASR) that is …

Early life stress is a risk factor for excessive alcohol drinking and impulsivity in adults and is mediated via a CRF/GABAA mechanism

2016

Childhood stress and trauma are associated with substance use disorders in adulthood, but the neurological changes that confer increased vulnerability are largely unknown. In this study, maternal separation (MS) stress, restricted to the pre-weaning period, was used as a model to study mechanisms of protracted effects of childhood stress/traumatic experiences on binge drinking and impulsivity. Using an operant self-administration model of binge drinking and a delay discounting assay to measure impulsive-like behavior, we report that early life stress due to MS facilitated acquisition of binge drinking and impulsivity during adulthood in rats. Previous studies have shown heightened levels of…

Haem Biosynthesis and Antioxidant Enzymes in Circulating Cells of Acute Intermittent Porphyria Patients

2016

The aims of the present study were to explore the expression pattern of haem biosynthesis enzymes in circulating cells of patients affected by two types of porphyria (acute intermittent, AIP, and variegate porphyria, VP), together with the antioxidant enzyme pattern in AIP in order to identify a possible situation of oxidative stress. Sixteen and twelve patients affected by AIP and VP, respectively, were analysed with the same numbers of healthy matched controls. Erythrocytes, neutrophils and peripheral blood mononuclear cells (PBMCs) were purified from blood, and RNA and proteins were extracted for quantitative real time PCR (qRT-PCR) and Western-blot analysis, respectively.
