Latvia. Human Development Report 2010/2011: National identity, Mobility and Capability

2011

The 2010/2011 report was produced under the auspices of the national research programme „National Identity”. The job of the report is to survey the content of individual national belonging in the context of human development. The report particularly focuses on emigration issues, because human development is weakened by a reduction in the size of the country’s population. The fact that people are moving to other countries shows that there is an endless competition among identities, as well as a transformation of those identities. The report also reveals the set of circumstances and techniques (the ability to act) which facilitate links between an individual and a location or region. The firs…

The influence of religious identity and socio-economic status on diet over time, an example from medieval France

2019

International audience; In Southern France as in other parts of Europe, significant changes occurred in settlement patterns between the end of Antiquity and the beginning of the Middle Ages. Small communities gathered to form, by the tenth century, villages organized around a church. This development was the result of a new social and agrarian organization. Its impact on lifestyles and, more precisely, on diet is still poorly understood. The analysis of carbon and nitrogen isotopes in bone collagen from the inhabitants of the well-preserved medieval rural site Missignac-Saint Gilles le Vieux (fifth to thirteenth centuries, Gard, France) provides insight into their dietary practices and enab…

Not all sex ratios are equal : the Fisher condition, parental care and sexual selection

2017

The term ‘sex roles’ encapsulates male–female differences in mate searching, competitive traits that increase mating/fertilization opportunities, choosiness about mates and parental care. Theoretical models suggest that biased sex ratios drive the evolution of sex roles. To model sex role evolution, it is essential to note that in most sexually reproducing species (haplodiploid insects are an exception), each offspring has one father and one mother. Consequently, the total number of offspring produced by each sex is identical, so the mean number of offspring produced by individuals of each sex depends on the sex ratio (Fisher condition). Similarly, the total number of heterosexual matings …

Propagule pressure increase and phylogenetic diversity decrease community’s susceptibility to invasion

2017

Background Invasions pose a large threat to native species, but the question of why some species are more invasive, and some communities more prone to invasions than others, is far from solved. Using 10 different three-species bacterial communities, we tested experimentally if the phylogenetic relationships between an invader and a resident community and the propagule pressure affect invasion probability. Results We found that greater diversity in phylogenetic distances between the members of resident community and the invader lowered invasion success, and higher propagule pressure increased invasion success whereas phylogenetic distance had no clear effect. In the later stages of invasion,…

Towards a Bangsamoro in Mindanao?

2017

Mindanao was already settled by Muslims when the Spanish colonization began. Today, the western part of the island and the Sulu archipelago are territories with a majority Muslim population, whereas the rest of the Philippines is predominantly Christian. Since the sixteenth century, the “Moros” of Mindanao have fought outsiders, Spaniards first, then the Americans, and throughout history the other Filipinos. The settlement migration policy of the Philippine government in the middle of the twentieth century has transformed the human landscape of the central and eastern parts of Mindanao, now predominantly Christian, and created a major area of commercial plantations. Political opposition to …

Analysis of T and NK cell subsets in Sicilian population from young to supercentenarian: the role of age and gender

2021

Summary Ageing dramatically affects number and function of both innate and adaptive arms of immune system, particularly T cell subsets, contributing to reduced vaccination efficacy, decreased resistance to infections and increased prevalence of cancer in older people. In the present paper, we analysed the age‐related changes in the absolute number of lymphocytes in 214 Sicilian subjects, and in the percentages of T and natural killer (NK) cells in a subcohort of donors. We compared these results with the immunophenotype of the oldest living Italian supercentenarian (aged 111 years). The results were also sorted by gender. The correlation between number/percentage of cells and age in all ind…

A Guide to Applying the Sex-Gender Perspective to Nutritional Genomics

2018

Precision nutrition aims to make dietary recommendations of a more personalized nature possible, to optimize the prevention or delay of a disease and to improve health. Therefore, the characteristics (including sex) of an individual have to be taken into account as well as a series of omics markers. The results of nutritional genomics studies are crucial to generate the evidence needed so that precision nutrition can be applied. Although sex is one of the fundamental variables for making recommendations, at present, the nutritional genomics studies undertaken have not analyzed, systematically and with a gender perspective, the heterogeneity/homogeneity in gene-diet interactions on the diffe…

2018

Sex differences in lifespan are ubiquitous, but the underlying causal factors remain poorly understood. Inter- and intrasexual social interactions are well known to influence lifespan in many taxa, but it has proved challenging to separate the role of sex-specific behaviours from wider physiological differences between the sexes. To address this problem, we genetically manipulated the sexual identity of the nervous system—and hence sexual behaviour—in Drosophila melanogaster , and measured lifespan under varying social conditions. Consistent with previous studies, masculinization of the nervous system in females induced male-specific courtship behaviour and aggression, while nervous system…

Minors and Transexuality

2020

[ES] En el ámbito de la transexualidad los poderes públicos han ejercido desde un principio una política claramente restrictiva que ha requerido de años para poder abrirse a las nuevas necesidades y a la sociedad actual. Así, la normativa en la materia era totalmente excluyente de los menores de edad, considerándolos carentes de aptitud alguna para poder decidir sobre su identidad sexual y todo lo que ello conllevaba, quizá porque como afirman algunos autores “la finalidad básica de esa prohibición es la de garantizar que la decisión de la rectificación registral sea una decisión firme y coherente, evitando así cambios arbitrarios o no fundados en el sexo” (Vázquez-Pastor, 2010).Esta idea p…

Proposed minimal standards for the use of genome data for the taxonomy of prokaryotes

2018

Advancement of DNA sequencing technology allows the routine use of genome sequences in the various fields of microbiology. The information held in genome sequences proved to provide objective and reliable means in the taxonomy of prokaryotes. Here, we describe the minimal standards for the quality of genome sequences and how they can be applied for taxonomic purposes.
