Harvest‐induced evolution and effective population size

2016

Much has been written about fishery-induced evolution (FIE) in exploited species, but relatively little attention has been paid to the consequences for one of the most important parameters in evolutionary biology-effective population size (N-e). We use a combination of simulations of Atlantic cod populations experiencing harvest, artificial manipulation of cod life tables, and analytical methods to explore how adding harvest to natural mortality affects N-e, census size (N), and the ratio N-e/N. We show that harvest-mediated reductions in N-e are due entirely to reductions in recruitment, because increasing adult mortality actually increases the N-e/N ratio. This means that proportional red…

Possible A2E Mutagenic Effects on RPE Mitochondrial DNA from Innovative RNA-Seq Bioinformatics Pipeline

2020

Mitochondria are subject to continuous oxidative stress stimuli that, over time, can impair their genome and lead to several pathologies, like retinal degenerations. Our main purpose was the identification of mtDNA variants that might be induced by intense oxidative stress determined by N-retinylidene-N-retinylethanolamine (A2E), together with molecular pathways involving the genes carrying them, possibly linked to retinal degeneration. We performed a variant analysis comparison between transcriptome profiles of human retinal pigment epithelial (RPE) cells exposed to A2E and untreated ones, hypothesizing that it might act as a mutagenic compound towards mtDNA. To optimize analysis, we propo…

Separated children & forbidden roots : removals of part-indigenous children as part of Australia's assimilation policy in the 1950s-1960s

2013

1950-ja 1960-luvuilla Australiassa oli kaksi merkittävää poliittista käytäntöä, joilla oli merkittävä vaikutus maan alkuperäisväestöön nimittäin assimilaatio sekä osittain valkoista alkuperää olevien aboriginaalilasten pakkohuostaanotot. Tutkielma käsittelee Australian assimilaatio politiikkaa, sen keinoja ja taustoja sekä varsinkin sen yhteyttä aboriginaalilasten pakkohuostaanottoihin. Jo 1800-luvulta lähtien Australiassa oli ollut vallalla käytäntö erottaa aboriginaalilapsia vanhemmistaan ja yhteisöistään koulutukset, parempien elinolojen tai kristillisen lähetystyön velvoittamana. Heistä koulutettiin halpaa, kristillistä työvoimaa valloitetuille alueille. 1920-luvulta alkanut osittain va…

Parenting Warmth and Strictness across Three Generations: Parenting Styles and Psychosocial Adjustment

2020

Recent emergent research is seriously questioning whether parental strictness contributes to children’s psychosocial adjustment in all cultural contexts. We examined cross-generational differences in parental practices characterized by warmth and practices characterized by strictness, as well as the relationship between parenting styles (authoritative, indulgent, authoritarian, and neglectful) and psychosocial adjustment in adulthood. Parenting practices characterized by warmth (affection, reasoning, indifference, and detachment) and strictness (revoking privileges, verbal scolding, and physical punishment) were examined. Psychosocial adjustment was captured with multidimensional self-conce…

An NDC approach to helping pensioners cope with the cost of long-term care

2018

The aim of this paper is to analyse whether it would be possible to provide retirement and long-term care benefits using the same unfunded notional defined contribution scheme. We extend the multi-state overlapping generations model developed by Pla-Porcel et al. (2016) to include two new features: a long-term care benefit graded according to the annuitant's degree of disability and a minimum pension benefit for both contingencies. This brings the model closer to the reality of social insurance and enhances its political attractiveness. The paper contains a numerical example to show how the model functions and focuses especially on the mortality rates for dependent persons, the inception ra…

Household Expenditure on Leisure: a Comparative Study of Italian Households with Children from Y- and Z-Generation

2019

The intrinsic complexity of post-materialist society makes it challenging to investigate the connection between social changes and generations. However, the study of consumption might help in the analysis of such a connection. In this paper, we analyse empirical data of consumption on leisure of Italian households, and focus on families at a very precise stage of family life-cycle, that is, couples with teenager children. We look at consumption of households at different points in time, 2001, 2007, and 2012, in order to investigate the impact of both social change and generation of children–Y-generation in 2001 and 2007, and Z-generation in 2012–on the leisure expenditure patterns of famili…

Political and relational: Autobiographical narrations of Latvian women across three generations

Piccole città per quarantenni. Sul senso di sé nella scrittura storiografica, in margine a un libro di Vanessa Roghi

2019

Starting from an analysis of Vanessa Roghi's recent book, Piccole città, we focus on the link between historiographic writing and autobiography. In particular, it analyzes the way this link changed at the end of the twentieth century, when political categories that had determined identities, even of historians, for more than a century, have finished. Since then, issues considered "private" have emerged in the public debate and in the historiographic debate, as happened for example with drug addiction, at the centre of Roghi's book.

Energy Consumption/Generation Model: Data collected, architecture conceived and scenarios addressed

2014

The paper provides the data collected, the architecture and the conceived scenarios for the development of an Energy Consumptions/Generations Model. This model is suitable for the modeling, processing, analyzing and forecasting of energy consumption and generation at home, building and neighborhood level. Data are from the Census Returns, Electoral Registers & Council of the real town of Loughborough (U.K.). The architecture conceived describes the real distribution system which supplies the Loughborough geographic area. The scenarios considered take into account both traditional dwellings (equipped with dumb appliances) and new dwellings (equipped with smart networked appliances) © 2014 IE…
