Validation and Measurement Invariance of the Scale of Positive and Negative Experience (SPANE) in a Spanish General Sample
2020
Este artículo se encuentra disponible en la siguiente URL: https://www.mdpi.com/1660-4601/17/22/8359 Este artículo pertenece a la sección "Health behavior, chronic disease and health promotion". Well-being has been measured based on di erent perspectives in positive psychology. However, it is necessary to measure a ects and emotions correctly and to explore the independence of positive and negative a ect. This cross-sectional study adapts and validates the Scale of Positive and Negative Experience (SPANE) with a non-probabilistic sample of 821 Spanish adults. A confirmatory factor analysis confirmed two related factors with two correlated errors. The average variance extracted was 0.502 for…
Decentering, Acceptance, and Non-Attachment : Challenging the Question "Is It Me?"
2021
Among mindfulness measures the three constructs acceptance, decentering, and non-attachment are psychometrically closely related, despite their apparent semantic differences. These three facets present robust psychometric features and can be considered core themes in most “third wave” clinical models. The aim of the present study was to explore the apparently different content domains (acceptance, decentering, and non-attachment) by administering various psychometric scales in a large sample of 608 volunteers. Resilience and depression were also assessed. Exploratory and confirmatory factor analyses performed in two randomly selected subsamples showed a bifactor approximation. The explained…
A Beggar, Self-Awareness And Willingness To Help
2008
The present field experiment examines the relationship between self-awareness, violation of personal space and helping behavior. A beggar asking for alms on the streets. To induce the first experimental condition, the state of objective self-awareness, the beggar had a mirror at chest height, suspended from a string round his neck. In the control condition, in place of the mirror, the beggar held a similarly dimensioned piece of cardboard in the same position. Both mirror and cardboard bore the message "A FEW PENNIES THANKS." As concerned the second experimental condition, the beggar either stood still waiting for people to come up to him, or walked toward the people as they approached, th…
Copper( ii ) complexes with phosphorylated 1,10-phenanthrolines: from molecules to infinite supramolecular arrays
2016
International audience; The reaction of phosphorylated 1,10-phenanthrolines 3-Pphen, 3,8-Pphen and 4,7-Pphen (3-Pphen = 3-diethoxyphosphorylphenanthroline, 3,8-Pphen = 3,8-bis(diethoxyphosphoryl) phenanthroline, 4,7-Pphen = 4,7-bis(diethoxyphosphoryl) phenanthroline) and hydrated copper(II) nitrate in a 1 : 1 ratio leads to the formation of supramolecular architectures. In the 1D coordination polymer [Cu(3-Pphen)(NO3)(2)](n) (2) the copper atom is coordinated to only one phenanthroline ligand and the coordination sphere is completed by two oxygen atoms of nitrate anions and the oxygen atom of the phosphoryl group from the neighbouring phenanthroline ligand. Complex Cu(3,8-Pphen)(NO3)(2) (3)…
Public procurement: current situation and points of improvement
2015
[ES] La construcción pública ha sido, es y será uno de los pilares fundamentales del sector construcción español, si bien la actual situación de crisis económica y la reducción de la inversión pública en nuevas infraestructuras ha generado un descenso de actividad hasta niveles similares a los años noventa. El retorno a índices de actividad más elevados no solo se conseguirá con la recuperación de la economía del país, sino que será necesario realizar ciertas mejoras en los procesos de licitación con objeto de conseguir una mayor funcionalidad y flexibilidad en la contratación pública de obras.
Journey to the Centre of Europe
1998
De nombreuses institutions locales utilisent, dans de véritables opérations de marketing territorial, une analogie entre centre géographique et centre géométrique du cercle pour valoriser leur localisation. Il s'agit là d'une conception particulière et étroite d'une idée plus riche et plus insaisissable. Le concept de centre est une construction économique et sociale mais il repose sur certains principes consensuels : l'accessibilité, la concentration,l'inégalité, la relativité spatiale et temporelle et la subjectivité compte tenu de sa dimension symbolique. Définir un centre c'est d'abord borner un sous espace de référence. Représenter le centre économique par le centre d'un cercle nécessi…
Functionalization of nanoparticles in specific targeting and mechanism release
2017
The development of various nanotechnologies have provided a new field of research, which allows the manipulation of molecular components of matter and covers a vast array of nanodevices. The “smart” multifunctional nanostructures should work as customizable, targeted drug-delivery vehicles capable of carrying large doses of therapeutic agents into malignant cells. Some nanomedical approaches are based on the use of functionalized nanoparticles (NPs), not only to reduce toxicity and side effects of drugs but, also in potential the biological barriers crossing on, such as: the blood–brain barrier, different cellular compartments, including the nucleus. Currently, many materials are used for n…
Filozof - przewodnik
2016
Starożytni stoicy uważali siebie za przewodników ludzi w kwestiach dotyczących tego, co zgodne z ich naturą. Udzielali porad, jak postępować w codziennych sprawach. Współcześnie niektórzy filozofowie kontynuują tę starożytną tradycję jako doradcy bądź trenerzy rozwoju osobistego. Czy są przewodnikami w sensie, w jakim byli nimi stoicy? Pytanie to stanie się myślą przewodnią rozważań podjętych w niniejszym wystąpieniu. Problemem podstawowym będzie poszukiwanie właściwej formuły, w jakiej można by było zamknąć współczesne filozoficzne przewodnictwo (kierownictwo duchowe) w sytuacji, gdy uznaje się, że nie może być ono prostym powielaniem starożytnych wzorów
Lower bound limit analysis by bem: Convex optimization problem and incremental approach
2013
Abstract The lower bound limit approach of the classical plasticity theory is rephrased using the Multidomain Symmetric Galerkin Boundary Element Method, under conditions of plane and initial strains, ideal plasticity and associated flow rule. The new formulation couples a multidomain procedure with nonlinear programming techniques and defines the self-equilibrium stress field by an equation involving all the substructures (bem-elements) of the discretized system. The analysis is performed in a canonical form as a convex optimization problem with quadratic constraints, in terms of discrete variables, and implemented using the Karnak.sGbem code coupled with the optimization toolbox by MatLab…
