Identificación con clubes y cultura futbolística en España. [Teams identification and football culture in Spain].
2013
Pese a la enorme relevancia del futbol en la sociedad espanola, algunas de sus pautas y procesos caracteristicos han sido poco examinados por la investigacion sociologica. Este articulo presenta una investigacion sobre la identificacion con los principales clubes de futbol en la sociedad espanola e incluye un analisis de los dos principales componentes de la cultura futbolistica de sus aficionados, esto es, la vinculacion y el compromiso personal con el club. El estudio se basa en una encuesta representativa de la poblacion espanola realizada en 2007 por el Centro de Investigaciones Sociologicas (CIS) que conto con una muestra de 2.473 entrevistas. Los resultados obtenidos ponen de manifies…
Strategies for Improving Optimal Positioning of Quality Sensors in Urban Drainage Systems for Non-Conservative Contaminants
2021
In the urban drainage sector, the problem of polluting discharges in sewers may act on the proper functioning of the sewer system, on the wastewater treatment plant reliability and on the receiving water body preservation. Therefore, the implementation of a chemical monitoring network is necessary to promptly detect and contain the event of contamination. Sensor location is usually an optimization exercise that is based on probabilistic or black-box methods and their efficiency is usually dependent on the initial assumption made on possible eligibility of nodes to become a monitoring point. It is a common practice to establish an initial non-informative assumption by considering all network…
The Influence of Emotion in the Management of Amateur Football Organizations.
2020
This article is oriented to the analysis of organisational and emotional variables in amateur sporting organizations. The general objective is to analyse the influence of organisational variables such as service quality, transactional leadership, and transformational leadership and emotional variables such as affective commitment, emotional attachment investment and emotional attachment dividend to predict the credibility that members of amateur sporting organisations perceive, as well as their degree of identification and loyalty. The opinions of 203 members of Chilean amateur football teams, (169 men and 34 women, with ages between 18 and 68 years (Mean=32.75 years, DT= 9.92) have been an…
Yksilöllisen oppimisen mallin soveltuvuus yläkoulun 7. luokan lajintuntemuksen opetukseen
2017
Suomalaisen koulujärjestelmän uudistuksia ohjaamaan astuivat elokuussa 2016 voimaan uudet valtakunnallisen perusopetuksen opetussuunnitelmien perusteet, jotka korostavat konstruktivistista oppimiskäsitystä ja tulevaisuuden osaamiseen valmentavia tietoja ja taitoja. Biologian opetuksen tehtävänä on kartuttaa oppilaan luonnontuntemusta yhteisöllisiä ja toiminnallisia opetusmenetelmiä hyödyntäen. Sen tulee myös ohjata oppilaiden luonnontieteellisen ajattelun kehitystä vuorovaikutuksessa muiden oppilaiden kanssa. Tämän tutkimuksen tavoitteena oli tutkia matemaatikko Pekka Peuran kehittelemän yksilöllisen oppimisen mallin soveltuvuutta lajintuntemuksen opetukseen biologian oppiaineessa yläkoulun…
System identification via optimised wavelet-based neural networks
2003
Nonlinear system identification by means of wavelet-based neural networks (WBNNs) is presented. An iterative method is proposed, based on a way of combining genetic algorithms (GAs) and least-square techniques with the aim of avoiding redundancy in the representation of the function. GAs are used for optimal selection of the structure of the WBNN and the parameters of the transfer function of its neurones. Least-square techniques are used to update the weights of the net. The basic criterion of the method is the addition of a new neurone, at a generic step, to the already constructed WBNN so that no modification to the parameters of its neurones is required. Simulation experiments and compa…
A systematic literature review of the transition to the circular economy in business organizations: Obstacles, catalysts and ambivalences
2021
There is a need for a transition from unsustainable linear business models to a more sustainable circular approach, called the circular economy. To promote this need, a deeper understanding of which issues hinder organizations’ transition to the circular economy and which ones catalyse it is needed. A systematic literature review was performed on the business implementation of the circular economy and 69 articles covering the topic were found. The review identifies different types of catalyst, obstacles and ambivalent factors influencing circular economy implementation in business. This study contributes to research on circular economy implementation at business organizations by providing u…
Resolving the Fe XXV triplet with Chandra in Centaurus X-3
2005
We present the results of a 45 ks Chandra observation of the high-mass X-ray binary Cen X-3 at orbital phases between 0.13 and 0.40 (in the eclipse post-egress phases). Here we concentrate on the study of discrete features in the energy spectrum at energies between 6 and 7 keV, that is, on the iron K alpha line region, using the High Energy Transmission Grating Spectrometer (HETGS) on board the Chandra satellite. We clearly see a K alpha neutral iron line at similar to 6.40 keV and were able to distinguish the three lines of the Fe xxv triplet at 6.61, 6.67, and 6.72 keV, with equivalent widths of 6, 9, and 5 eV, respectively. The equivalent width of the Ka neutral iron line is 13 eV, an or…
Blue-copper binding proteins of Medicago truncatula: Characterization of the expression of two genes related to the arbuscular mycorrhizal symbiosis
2009
International audience; Expression profiling of two paralogous arbuscular mycorrhizal (AM)-specific blue copper-binding gene (MtBcpla and MtBcp1b) isoforms was performed by real-time quantitative polymerase chain reaction in wild-type Medicago truncatula Jemalong 5 (J5) during the mycorrhizal development with Glomus intraradices for up to 7 weeks. Timecourse analysis in J5 showed that expression of both MtBcp1 genes increased continuously and correlated strongly with the colonization intensity and arbuscule content. MtPT4, selected as a reference gene of the functional plant-fungus association, showed a weaker correlation to mycorrhizal development. In a second experiment, a range of mycorr…
The guanxi ties of managers in mainland China – a critical analysis based on gender
2018
Purpose Inadequate social networks are often seen as an explanation of the under-representation of women in management. Networks contain culture-specific features, as in China where the term guanxi is used, defined as a shared common identification held by two or more individuals (Jacobs, 1979). In several studies, guanxi has been found to relate positively to success at work both for the individual and the organization, but little is known about it from gender and career perspectives. Referring especially to the earlier studies by Chow and Ng (2004), the purpose of this paper is to address the meaning of guanxi networks for top women IT managers in mainland China.
