Przejawy zjawiska parentyfikacji wśród dzieci ukraińskich na skutek migracji i uchodźstwa

2022

Celem opracowania jest wstępna odpowiedź na pytanie: Jakie czynniki sprzyjają, a jakie mogą zapobiec zaistnieniu zjawiska odwrócenia ról (parentyfikacji) w ukraińskich rodzinach uchodźczych mieszkających w Polsce? W pierwszej części artykułu wyjaśniono zjawisko parentyfikacji, następnie ukazano genezę wybuchu wojny hybrydowej na Ukrainie. W kolejnej części tekstu przedstawiono metodologię eksploracyjnych badań jakościowych – wywiad pogłębiony (wśród ukraińskich matek) i wywiad ekspercki (wśród terapeutów zaangażowanych w pomoc ukraińskim rodzinom). Przeprowadzono też analizę porównawczą omawianego kontekstu z wybranymi przypadkami parentyfikacji wśród migrantów w Europie. Badania wskazały d…

Growth and defense in deciduous trees and shrubs under UV-B

2005

Abstract Reflection by waxy or resinous surface structures and hairs, repair reactions of biomolecules and induction of different sheltering components provide the means of plant protection from harmful solar UV-B radiation. Secondary products, especially flavonoids and phenolic acids as defense components are also important in plant tolerance to UV-B, fulfilling the dual role as screens that reduce UV-B penetration in plant tissues, and as antioxidants protecting from damage by reactive oxidant species. Plants are sensitive to UV-B radiation, and this sensitivity can be even more clone-specific than species-specific. The results available in the literature for deciduous trees and shrubs in…

La investigación en docencia en dirección de operaciones: Tendencias y retos

2011

[EN] Purpose: The objective is to analyse research in Operations Management (OM) teaching published in high impact journals in the area in order to examine trends and set future challenges. Design/methodology/approach: A bibliometric study was carried out of 45 of the main JCR OM and Management journals for the 1995-2010 period. The 129 articles identified on research in OM teaching were analysed. Findings: There is a dearth of articles on teaching in the main OM and Management journals. Sixty-two point two percent of the journals analysed have not published any and the remainder (17) have devoted only 0.4% of all their publications to this subject area. Descriptive and theoretical/conceptu…

Classification par méthodes d’apprentissage supervisé et faiblement superviséd’images multimodales pour l’aide au diagnostic du lentigo malin en derm…

2021

Carried out in collaboration with the Saint-Étienne University Hospital, this work provides additional information to help the skin diagnosis by providing new decision methods on Lentigo Maligna and Lentigo Maligna Melanoma pathologies. To this end, the modalities regularly used in clinical conditions are made available to this work and are orchestrated within a multimodal process. Among image modalities, may be mentioned the clinical photography, the dermatoscopy, and the confocal reflectance microscopy. Initially, the first steps of this manuscript focus on reflectance confocal microscopy as the work in computer diagnostic assistance is relatively underdeveloped, in particular on the dete…

The effect of cooperative infrastructure fees on high-speed rail and airline competition

2021

Abstract This paper explores the effects of cooperation between rail and air infrastructures in setting per-passenger fees prior to competition among airlines and high-speed rail (HSR) in a transport network. It is shown that, for a sufficiently low degree of substitution, cooperation results in lower fees and greater HSR traffic than under competition. Besides, it leads to more connecting passengers. An empirical application allows for a quantitative assessment of cooperation. Gains to passengers and operators are sizeable when cooperation either involves all infrastructure managers or the rail and the hub airport managers. Welfare gains are in the range of 10.4–11.1%. Our contribution off…

Structural Vibration Control for a Class of Connected Multistructure Mechanical Systems

2012

Published version of an article from the journal: Mathematical Problems in Engineering. Also available from the publisher:http://dx.doi.org/10.1155/2012/942910 A mathematical model to compute the overall vibrational response of connected multistructure mechanical systems is presented. Using the proposed model, structural vibration control strategies for seismic protection of multibuilding systems can be efficiently designed. Particular attention is paid to the design of control configurations that combine passive interbuilding dampers with local feedback control systems implemented in the buildings. These hybrid active-passive control strategies possess the good properties of passive contro…

Discrete-time multioverlapping controller design for structural vibration control of tall buildings under seismic excitation

2012

Published version of an article from the journal: Mathematical Problems in Engineering. Also available from the publisher:http://dx.doi.org/10.1155/2012/636878 In this paper, a computationally effective strategy to obtain multioverlapping controllers via the Inclusion Principle is applied to design discrete-time state-feedback multioverlapping LQR con- trollers for seismic protection of tall buildings. To compute the corresponding control actions, the proposed semidecentralized controllers only require state information from neighboring stories. This particular configuration of information exchange allows introducing a dramatic reduction in the transmission range required for a wireless imp…

Active-passive control strategy for adjacent buildings

2011

Author's version of a chapter in the book: 2011 Proceedings of the American Control Conference. Also available from the publisher at: http://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=05991059 In this paper, a control strategy to mitigate the vibrational response of adjacent buildings under seismic excitation is presented. The proposed strategy combines inter-building passive actuators with active actuators placed in the building stories. The main ideas are presented by means of a simplified two-building model; however, a semi-decentralized overlapping approach via the inclusion principle has been used to impose a proper information exchange structure suitable for wireless control of larg…

Semi-decentralized strategies in structural vibration control

2011

Published version of an article published in the journal: Modeling, Identification and Control. Also available from the publisher at: http://dx.doi.org/10.4173/mic.2011.2.2 In this work, the main ideas involved in the design of overlapping and multi-overlapping controllers via the Inclusion Principle are discussed and illustrated in the context of the Structural Vibration Control of tall buildings under seismic excitation. A detailed theoretical background on the Inclusion Principle and the design of overlapping controllers is provided. Overlapping and multi-overlapping LQR controllers are designed for a simplied five-story building model. Numerical simulations are conducted to asses the pe…
