Profiles of subjective health among people living alone: a latent class analysis

open access: yesBMC Public Health, 2021
Background Living alone has increased globally and especially in Finland where 45% of all households are single occupancy. Epidemiological research has found that living alone a risk factor for a wide range of adversities related to quality of life but ...

Trace Element Discrimination Diagrams for the Tectonic Interpretation of Granitic Rocks

open access: yes, 1984
Granites may be subdivided according to their intrusive settings into four main groups—ocean ridge granites (ORG), volcanic arc granites (VAG), within plate granites (WPG) and collision granites (COLG)—and the granites within each group may be further ...

Perceived discrimination and health: a meta-analytic review.

open access: yesPsychological bulletin, 2009
Perceived discrimination has been studied with regard to its impact on several types of health effects. This meta-analysis provides a comprehensive account of the relationships between multiple forms of perceived discrimination and both mental and ...

Landau discriminants

open access: yesJournal of High Energy Physics, 2022
Abstract Scattering amplitudes in quantum field theories have intricate analytic properties as functions of the energies and momenta of the scattered particles. In perturbation theory, their singularities are governed by a set of nonlinear polynomial equations, known as Landau equations, for each individual Feynman diagram.

EVALUATING THE IMPACT OF DATA.GOV.RO ON THE ACADEMIC RESEARCH [PDF]

open access: yesAnalele Universităţii Constantin Brâncuşi din Târgu Jiu : Seria Economie, 2022
In the context of the digital revolution, data is the most valuable resource which gains in value the more it is used. Freely available open source data and institutional data repositories encourage and connect, both academia and industry.

Iterated discriminants

open access: yesJournal of Symbolic Computation, 2009
It is shown that the discriminant of the discriminant of a multivariate polynomial has the same irreducible factors as the product of seven polynomials each of which is defined as the GCD of the generators of an elimination ideal. Under relatively mild conditions of genericity, three of these polynomials are irreducible and generate the corresponding ...

School‐based law enforcement strategies to reduce crime, increase perceptions of safety, and improve learning outcomes in primary and secondary schools: A systematic review

open access: yesCampbell Systematic Reviews, 2023
Background School‐based law enforcement (SBLE) has become a common intervention. Although SBLE is meant to make schools safer, critics suggest it may not accomplish this purpose, and may have unintended negative consequences such as increasing students ...

Memory, Visual Discrimination Performance, and the Human Hippocampus

open access: yesJournal of Neuroscience, 2011
We evaluated recent proposals that the hippocampus supports certain kinds of visual discrimination performance, for example, when spatial processing is required and the stimuli have a high degree of feature overlap.

A-type granites: geochemical characteristics, discrimination and petrogenesis

open access: yes, 1987
New analyses of 131 samples of A-type (alkaline or anorogenic) granites substantiate previously recognized chemical features, namely high SiO2, Na2O+K2O, Fe/Mg, Ga/Al, Zr, Nb, Ga, Y and Ce, and low CaO and Sr.

Statistical discrimination and statistical informativeness [PDF]

open access: yesarXiv, 2022
We study the link between Phelps-Aigner-Cain-type statistical discrimination and familiar notions of statistical informativeness. Our central insight is that Blackwell's Theorem, suitably relabeled, characterizes statistical discrimination in terms of statistical informativeness.
