Effects of selected pro-environmental project in the regional development of Poland
2019
Zgodnie z założeniami Strategii Europa 2020 wobec państw członkowskich wyznaczono cele w ramach prowadzonej polityki rozwoju. Równocześnie Polska, jako jeden z beneficjentów programów operacyjnych, korzysta z pomocy finansowej UE, realizując projekty na rzecz środowiska, gospodarki niskoemisyjnej, a szerzej − rozwoju zrównoważonego i trwałego. Celem artykułu jest zidentyfikowanie oddziaływania projektów o charakterze prośrodowiskowym na rozwój województw Polski. Analizie poddano inicjatywy realizowane w ramach programów operacyjnych w okresie programowania 2014-2020. Ponadto określono poziomy rozwoju województw Polski w wybranych latach. Zastosowano taksonomiczne metody badawcze Z. Hellwiga…
Lavoro e rappresentanza, cinquant’anni dopo il '68
2018
L'articolo ripercorre i tratti essenziali del ciclo di protesta operaia del '68 mostrando la portata dei cambiamenti che hanno attraversato il lavoro e la rappresentanza negli ultimi 50 anni, cambiamenti che sembrano condensarsi sulla categoria dei giovani lavoratori, ieri avanguardia del cambiamento, oggi i principali esclusi dal lavoro e dalla rappresentanza.
Multifacial Recognition in Binary and Ternary Cocrystals from 5-Halouracil and Aminoazine Derivatives
2018
A systematic analysis using single crystal X-ray diffraction was performed to explore the role exerted by potential intercomponent proton-transfer reactions in the supramolecular structures of A–B cocrystals formed by 5-haloderivatives of uracil (A), coupled with 2-aminoadenine simulants (aminoazines, B). Twelve new heterodimers were synthesized in different stoichiometries and cocrystallized by solvent cogrinding followed by solution crystallization. In the binary cocrystals, uracil or 1-methyluracil with halide modification at the 5 position (F, Cl, Br, I) was coupled with amino-aromatic N-heterocycles (melamine, 2,4,6-triaminopyrimidine, 2,6-diaminopyridine) as a multivalent site for pyr…
Scheduling under the network of temporo-spatial proximity relationships
2017
We discuss and introduce to the schedulingeld a novel, qualitative optimization model - scheduling under the network of temporo-spatial proximity relationships.We introduce a half perimeter proximity measure as an objective of scheduling.We present and evaluate an incremental Sequence Pair neighborhood evaluation algorithm, applicable to both scheduling and rectangle packing problems in VLSI industry. In this paper, we discuss and introduce to the scheduling field a novel optimization objective - half perimeter proximity measure in scheduling under the network of temporo-spatial proximity relationships. The presented approach enables to qualitatively express various reasons of scheduling ce…
MR3535311 Reviewed Inoue, H.(J-KYUSGM); Takakura, M.(J-FUE-AM) Regular biorthogonal pairs and pseudo-bosonic operators. (English summary) J. Math. Ph…
2017
Given a pair of operators a and b acting on a Hilbert space H, such that [a,b]=1, the authors give a method to construct a regular bi-orthogonal pair of sequences in H. They study the relationship between the conditions on a,b,a†,b† and the operators Ae,Be,A†e,B†e, considered by one of the authors in a previous paper, in the set-up of a general theory of bi-orthogonal pair sequences. Then they give a method to construct operators A and B with the so-called D-pseudo bosons conditions, i.e. the commutation rule and some assumptions, on a dense subspace D of H, considered in the literature. Finally, some physical examples are given.
The existence of solutions for the modified (p(x), q(x))-Kirchhoff equation
2022
We consider the Dirichlet problem-Delta(Kp)(p(x))u(x) - Delta(Kq)(q(x))u(x) = f(x, u(x), del u(x)) in Omega, u vertical bar(partial derivative Omega) = 0,driven by the sum of a p(x)-Laplacian operator and of a q(x)-Laplacian operator, both of them weighted by indefinite (sign-changing) Kirchhoff type terms. We establish the existence of weak solution and strong generalized solution, using topological tools (properties of Galerkin basis and of Nemitsky map). In the particular case of a positive Kirchhoff term, we obtain the existence of weak solution (= strong generalized solution), using the properties of pseudomonotone operators.
Validation of a Work Engagement Scale. Profi les associated with high Performance and Job Satisfaction
2017
El objetivo principal de este estudio consistía en la validación de una escala para la evaluación del work engagement -compromiso con el trabajo-, considerado como una presencia psicológica en el rol que incluye atención, absorción y energía dirigida a tareas laborales. Mediante análisis factorial confirmatorio, estimación de la consistencia interna y evidencias de validez convergente y discriminante, se confirma que la Escala Argentina de Compromiso con el Trabajo es una prueba válida y confiable para su uso en población argentina. Además, se buscó analizar si existen diferencias en los niveles de work engagement de acuerdo con variables individuales y organizacionales. Se observaron mayor…
Estudio médico-legal de los casos de asesinatos en serie sucedidos en España en los últimos treinta años (1984-2014)
2018
El asesino en serie es visto hoy en día como uno de los grandes depredadores humanos de nuestra sociedad. Constituye un problema y un gran reto para aquellos que se enfrentan a este tipo de violencia, tanto al tratar de atajarla como de prevenirla. Como en cualquier otro tipo de delito, conocer y comprender su génesis, sus motivaciones y los factores que lo integran es trascendental para abordar el problema. España no es ajena a este tipo de violencia. No son pocos los homicidas que han presentado tal clase de patrón en los últimos años. El presente trabajo trata de analizar los casos de asesinatos seriales que se han dado en nuestro país en las tres últimas décadas, entre 1984 y 2014, una …
Działania psychologiczne w aspekcie wyzwań XXI wieku
2016
The article concentrates on possibilities of taking advantage of deception operations by human intelligence, electronics intelligence and in psychological operations. Psychological operations are planned activities using methods of communication and other means directed at approved audiences in order to influence perceptions, attitudes and behaviour, affecting the achievement of political and military objectives.
Le cause di esclusione di cui all’art. 80 D.Lgs. n. 50/2016 tra Linee guida dell’ANAC e principi di tassatività e legalità
2017
This paper, concerning the Guidelines adopted by the ANAC on the subject of "Indication adequate means of proof and deficiencies in the performance of a previous procurement contract which may be considered significant for demonstrating the circumstances of exclusion pursuant to art. 80 paragraph 5, lett. c) of the code”, aims to highlight on the one hand how, the alleged optional nature of the same, recognizing to the individual contracting stations the right to decide on the applicability of the Lines themselves, could, on the one hand, lead to situations potentially harmful to the constitutional principles pursuant to articles 3, 41 and 117, paragraph 2, lett. e) of the Constitution, to …
