Manipulating the alpha level cannot cure significance testing

2018

We argue that making accept/reject decisions on scientific hypotheses, including a recent call for changing the canonical alpha level from p = 0.05 to p = 0.005, is deleterious for the finding of new discoveries and the progress of science. Given that blanket and variable alpha levels both are problematic, it is sensible to dispense with significance testing altogether. There are alternatives that address study design and sample size much more directly than significance testing does; but none of the statistical tools should be taken as the new magic method giving clear-cut mechanical answers. Inference should not be based on single studies at all, but on cumulative evidence from multiple in…

Parents or Peers? Predictors of Prosocial Behavior and Aggression: A Longitudinal Study

2019

The aim of this longitudinal study was to determine the associations among peer attachment, warmth from the mother and father, strict control by the mother and father, prosocial behavior, and physical and verbal aggression in adolescence. Few longitudinal studies have examined how peer attachment and parenting styles of the mother and father relate to prosocial behavior and aggression. Participants were 192 boys and 255 girls (M = 14.70 years; SD = 0.68) in wave 1. In the study participated 11 schools. For three successive years, participants reported on their fathers’ and mothers’ warmth and strict control, peer attachment, prosocial behavior, and aggression. Structural equations modeling …

Chemical and photochemical properties of chloroharmine derivatives in aqueous solutions

2015

Thermal and photochemical stability (ΦR), room temperature UV-vis absorption and fluorescence spectra, fluorescence quantum yields (ΦF) and lifetimes (τF), quantum yields of hydrogen peroxide (ΦH2O2) and singlet oxygen (ΦΔ) production, and triplet lifetimes (τT) have been obtained for the neutral and protonated forms of 6-chloroharmine, 8-chloroharmine and 6,8-dichloroharmine, in aqueous media. When it was possible, the effect of pH and oxygen concentration was evaluated. The nature of electronic transitions of protonated and neutral species of the three investigated chloroharmines was established using Time-Dependent Density Functional Theory (TD-DFT) calculations. The impact of all the fo…

Analysis of Business Elite Networks and Revolving Doors in Mexico : Cartography of a Public-Private Ruling Class

2020

La presente investigación mapea las redes de las élites empresariales y políticas en México para comprender la organización social y la capacidad de influencia de las élites mexicanas, y abrir vías de investigación sobre las élites de poder en México. En primer lugar, se realiza un estudio de la cohesión interna de las élites empresariales mediante un análisis de redes de interlocking directorates y enlaces de propiedad. En segundo lugar, se examinan varios casos de puertas giratorias mediante un análisis prosopográfico de biografías y trayectorias. Los resultados revelan que las élites empresariales mexicanas están cohesionadas y que existe un grupo de individuos que fluctúan entre el sect…

Third family of compact stars within a nonlocal chiral quark model equation of state

2019

A class of hybrid compact star equations of state is investigated that joins by a Maxwell construction a low-density phase of hadronic matter, modeled by a relativistic mean-field approach with excluded nucleon volume, with a high-density phase of color superconducting two-flavor quark matter, described within a nonlocal covariant chiral quark model. It is found that the occurrence of a stable branch of hybrid compact stars requires a nonvanishing vector meson coupling in the quark model that exceeds a minimal value which depends on the presence of a diquark condensate. It is shown that these hybrid stars do not form a third family disconnected from the second family of ordinary neutron sta…

Nuclear and partonic dynamics in the EMC effect

2013

It has been recently confirmed that the magnitude of the EMC effect measured in the electron deep inelastic scattering is linearly related to the short-range correlation scaling factor obtained from electron inclusive scattering. By using a x-rescaling approach we are able to understand the interplay between the quark-gluon and hadronic degrees of freedom in the discussion of the EMC effect.

Victimization at school: relationship of parenting and functional-dysfunctional developmental variables

2015

El presente estudio tiene como principal objetivo analizar elpapel diferencial de la crianza (apoyo y comunicación versus control), devariables funcionales del desarrollo (empatía y mecanismos de afrontamientofuncionales) y las variables disfuncionales (inestabilidad emocional yafrontamiento improductivo) en la victimización ocurrida en el entorno escolar,o por el contrario, con el apego entre pares. Participaron en el estudio418 alumnos, 224 chicas y 194 chicos adolescentes, entre 13 y 14 años,escolarizados en los niveles de 3º y 4º curso de Educación SecundariaObligatoria. Para analizar estas relaciones se llevó a cabo un modelo deecuaciones estructurales EQS. Los resultados obtenidos mue…

Descartes on Corporeal Substances

2015

I defend in this paper the following two theses: first, that Descartes was a Pluralist as regards extended substances, that is, that for him the extended world includes a plurality of bodies, including ordinary objects, each of which may be adequately described as a substance; and that for him the notion of substance is a rather slim notion, making no specific requirements as regards individuation or persistence conditions, and determining therefore no strict constraints on the kind of material objects that may count as substances. In short, I will be arguing for a certain view concerning the extension of the phrase ‘extended substance’ by defending a specific view of what ‘substance’ means…

Study of the material of the ATLAS inner detector for Run 2 of the LHC

2017

The ATLAS inner detector comprises three different sub-detectors: the pixel detector, the silicon strip tracker, and the transition-radiation drift-tube tracker. The Insertable B-Layer, a new innermost pixel layer, was installed during the shutdown period in 2014, together with modifications to the layout of the cables and support structures of the existing pixel detector. The material in the inner detector is studied with several methods, using a low-luminosity root s = 13 TeV pp collision sample corresponding to around 2.0 nb(-1) collected in 2015 with the ATLAS experiment at the LHC. In this paper, the material within the innermost barrel region is studied using reconstructed hadronic in…
