Dating in adolescence plays an integral part in the development of sexual and social identities. This process is particularly salient for sexual minority youth who face additional obstacles to their identity formation due to their marginalized status. We investigated the influence of participating in a same-sex relationship (SSR) or an opposite-sex relationship (OSR) on sexual minority youths' ...

The effect of nest aggregation in courtship behaviour was tested experimentally in an ecologically constrained, sex-role reversed population of the peacock blenny Salaria pavo. Mixed sex groups of eight males and eight females were tested in experimental tanks, containing eight potential nests either aggregated or dispersed. In the aggregated treatment, males spent more time inside their nests ...

Skewed sex ratios - operational (OSR) and Adult (ASR) - arise from sexual differences in reproductive behaviours and adult survival rates due to the cost of reproduction. However, skewed sex-ratio at birth, sex-biased dispersal and immigration, and sexual differences in juvenile mortality may also contribute. We present a framework to decompose the roles of demographic traits on sex ratios usin...

The Ottosen–Stenström–Ristinmaa (OSR) incremental fatigue damage model, based on an moving endurance surface centered around a backstress, is adapted for high-cycle at stress-raisers in AA7050-T7 specimens. Fatigue experiments are carried out circumferentially-notched, axisymmetric specimens subjected to constant-amplitude (CA) load. OSR model parameters fitted CA data, showing fair agreement o...

The aim of the paper is to assess relative merits two formal representations structure, namely, set theory and category theory. purpose articulate ontic structural realism (OSR). In turn, this will facilitate a discussion on strengths weaknesses both concepts, lead proposal for pragmatics-based approach question choice an appropriate framework. First, we present case study from contemporary sci...

Rapid and accurate yield estimates at both field regional levels remain the goal of sustainable agriculture food security. Hereby, identification consistent reliable methodologies providing predictions is one hot topics in agricultural research. This study investigated relationship spatiotemporal fusion modelling using STRAFM on crop prediction for winter wheat (WW) oil-seed rape (OSR) a semi-e...

The framework conditions for chemical weed control in oilseed rape (OSR) are becoming increasingly unfavorable Central Europe. On the one hand, resistance is spreading and, on other, there a growing social desire to reduce or eliminate use of crop protection products. In field experiment, hoeing, as measure performed two times per season (one time autumn and spring) (Brassica napus; varieties),...

Abstract The optimal sequenced route (OSR) query, as a popular problem in planning for smart cities, searches minimum-distance passing through several POIs specific order from starting position. In reality, are usually rated, which helps users making decisions. Existing OSR queries neglect the fact that same category could have different scores, may affect users’ choices. this paper, we study n...
