SPAIN: Evolution and Characteristics of the Private Sport Sector – Focus on Fitness Centres and Gyms

2017

This chapter contains a description of the evolution and main characteristics of the private sport sector in Spain. The first section outlines a panoramic vision of the structure and organizational framework of the Spanish sport sector, illustrating the established supremacy of the public sector above the voluntary and private sectors. Next, an analysis is laid out, utilising data from Section 931 of the Central Business Register of the National Institute of Statistics. This analysis includes information pertaining to the number of existing organisations, legal structures, number of employees, and territorial layouts. Once the general description of Spain’s private sport sector is covered, …

Towards a novel conceptual framework for understanding mergers in higher education

2015

ABSTRACTThis paper tries to develop a conceptual framework for a comprehensive understanding of the merger process, which is regarded as a matter of institutionalization of organizational innovation. In the framework, a number of factors affecting merger process or institutionalization of merger are identified, such as those related to environmental issues, economic benefits, institutional compatibility and human agency. The framework hopefully narrows our knowledge gap on theorizing innovation process, in general, and university merger, in particular. It also has a potential to better assist decision-makers and managers in planning and implementing university mergers.

Overview and performance comparison of grid synchronization algorithms

2014

Distributed power generation units are experiencing an impressive growth. Consequently, the amount of energy injected by non-linear loads as power converters is expected to increase. Stability and quality of the overall grid are heavily affected by performances of grid-side converters. In this paper, an overview of grid-synchronization technique is proposed. The grid-side inverter is implemented in MATLAB/Simulink® environment including current control and grid-synchronization section. Both Synchronous Reference Frame (SRF) and Decoupled Double Synchronous Reference Frame (DDSRF) PLL algorithms are implemented. A performance comparison is carried out under ideal and unbalanced utility condi…

Highly stable and porous porphyrin-based zirconium and hafnium phosphonates – electron crystallography as an important tool for structure elucidation

2018

The Ni-metallated porphyrin-based tetraphosphonic acid (Ni-tetra(4-phosphonophenyl)porphyrin, Ni-H8TPPP) was used for the synthesis of highly porous metal phosphonates containing the tetravalent cations Zr4+ and Hf4+. The compounds were thoroughly characterized regarding their sorption properties towards N2 and H2O as well as thermal and chemical stability. During the synthesis optimization the reaction time could be substantially decreased under stirring from 24 to 3 h in glass vials. M-CAU-30, [M2(Ni-H2TPPP)(OH/F)2]·H2O (M = Zr, Hf) shows exceptionally high specific surface areas for metal phosphonates of aBET = 1070 and 1030 m2 g-1 for Zr- and Hf-CAU-30, respectively, which are very clos…

Measurement of isolated-photon pair production in pp collisions at root s=7 TeV with the ATLAS detector

2013

The ATLAS experiment at the LHC has measured the production cross section of events with two isolated photons in the final state, in proton-proton collisions at √s = 7 TeV . The full data set collected in 2011, corresponding to an integrated luminosity of 4.9 fb[superscript −1], is used. The amount of background, from hadronic jets and isolated electrons, is estimated with data-driven techniques and subtracted. The total cross section, for two isolated photons with transverse energies above 25 GeV and 22 GeV respectively, in the acceptance of the electromagnetic calorimeter (|η|  0.4, is 44.0[+3.2 over −4.2] pb. The differential cross sections as a function of the di-photon invariant mass, …

Fostering creative thinking : the role of primary teachers

2014

Τα τελευταία χρόνια παρατηρείται μια αυξανόμενη απαίτηση για δημιουργικότητα σε όλους τους τομείς της ανθρώπινης δραστηριότητας. Η πρωτοβάθμια εκπαίδευση πασχίζει να συμβαδίσει με τις νέες κοινωνικοοικονομικές ανάγκες και να προετοιμάσει τους δημιουργικούς πολίτες του μέλλοντος. Αν και οι εκπαιδευτικοί της πρωτοβάθμιας εκπαίδευσης παίζουν καθοριστικό ρόλο, άλλοτε θετικό και άλλοτε αρνητικό, στην καλλιέργεια της δημιουργικότητας των μαθητών, λίγες έρευνες έχουν διεξαχθεί σχετικά με τη συμβολή τους στην καλλιέργεια της δημιουργικής σκέψης των μαθητών και τις απόψεις τους για το θέμα αυτό. Η θεμελιωμένη γνώση (situated knowledge) των Ελλήνων εκπαιδευτικών πρωτοβάθμιας εκπαίδευσης και η εμπειρί…

Effectiveness of hexavalent vaccines against invasive Haemophilus influenzae type b disease: Germany's experience after 5 years of licensure

2007

Summary Vaccine effectiveness (VE) was determined with a case-cohort approach using Cox regression. Cases with confirmed systemic Hib infections in children born from 1 August 2000 to 31 December 2004 were ascertained through two independent nationwide active surveillance systems. A representative cohort of 1303 children born in the same time frame was randomly sampled in a nationwide immunisation survey. Thirty cases were eligible for VE calculation; 19 were unvaccinated and 11 vaccinated with hexavalent vaccines. VE was 68.4% (95% CI: 19.0–87.6) for incomplete primary series and 90.4% (95% CI: 70.6–96.8) for the full primary series. For full immunisation VE was 100.0% (95% CI: 52.7–100.0)…
