Volunteer satisfaction in sports clubs: A multilevel analysis in 10 European countries

2020

Regular voluntary engagement is a basic resource for sports clubs that may also promote social cohesion and active citizenship. The satisfaction of volunteers is an imperative factor in this engagement, and the purpose of this article is to explore individual and organizational determinants of volunteer satisfaction in sports clubs. Theoretically, our study builds on the actor-theory concepts where volunteer satisfaction depends on subjective evaluations of expectations and experiences in a sports club (‘logic of situation’), so that positive evaluations lead to higher satisfaction and, hopefully, retention of volunteers. This research uses a sample of 8131 volunteers from 642 sports clubs…

Nurturing, breadwinning, and upbringing: paternal responsibilities by Finnish men in early fatherhood

2014

In the Nordic countries, including Finland, gender-balanced distribution of childcare is both the goal of family policies and nowadays also a cultural norm of parenting. Thus, in most families, the father, along with the mother, plays a considerable role in handson care. This study captures and analyzes paternal responsibilities as narrated by Finnish fathers. It draws on 32 interviews with 16 fathers conducted during the first three years of their fatherhood, and applies the method of narrative inquiry, in which narratives are understood as constructors of knowledge. The analysis yielded nurturing, breadwinning and upbringing, framed by the levels of everyday duties and comprehensive commi…

Situation-specificity of children's social goals: Changing goals according to changing situations?

2007

Children's agentic and communal goals were examined in hypothetical conflict, group entry, victimization, and positive situations ( N = 310, 11—13 years). Multilevel modeling was used to separate the variation in goals to the between- and within- (i.e., situation-specific) individual levels. About half of the variation in goals was due to individual differences. Boys endorsed more agentic goals than girls. A positive perception of self was associated with more agentic goals, whereas a positive perception of peers was associated with high degrees of communal goals. In addition, agentic goals were associated with rejection, whereas communal goals were related to peer acceptance. Children aim…

Automated Integration and Communication Synthesis of Reconfigurable MPSoC Platform

2007

The communication synthesis is the main problematic in the multiprocessor system-on-chip (MPSoC). To resolve this problem, several methodologies can be used. These methodologies require automated methods to specify, generate and optimize the hardware, software, and the architectural interfaces between them. In this paper, we present a methodology flow for hardware-software communication synthesis for multiprocessor system-on-chip platform which are dedicated to streaming applications. Our methodology consists of high level architecture communication synthesis from functional description of the MPSoC design. The solution that we propose consists in synthesizing a custom bus architecture for …

Modified Landau levels, damped harmonic oscillator and two-dimensional pseudo-bosons

2010

In a series of recent papers one of us has analyzed in some details a class of elementary excitations called {\em pseudo-bosons}. They arise from a special deformation of the canonical commutation relation $[a,a^\dagger]=\1$, which is replaced by $[a,b]=\1$, with $b$ not necessarily equal to $a^\dagger$. Here, after a two-dimensional extension of the general framework, we apply the theory to a generalized version of the two-dimensional Hamiltonian describing Landau levels. Moreover, for this system, we discuss coherent states and we deduce a resolution of the identity. We also consider a different class of examples arising from a classical system, i.e. a damped harmonic oscillator.

The Impact of Shadowing and the Severity of Fading on the First and Second Order Statistics of the Capacity of OSTBC MIMO Nakagami-Lognormal Channels

2011

Published version of an article in Wireless Personal Communications (2011), 1-16. Also available from the publisher at http://dx.doi.org/10.1007/s11277-011-0275-x This article presents a thorough statistical analysis of the capacity of orthogonal space-time block coded (OSTBC) multiple-input multiple-output (MIMO) Nakagami- lognormal (NLN) channels. The NLN channel model allows to study the joint effects of fast fading and shadowing on the statistical properties of the channel capacity. We have derived exact analytical expressions for the probability density function (PDF), cumulative distribution function (CDF), level-crossing rate (LCR), and average duration of fades (ADF) of the capacity…

Super Resolution Methods Implementing Diffractive Masks Having a Certain Degree of Periodicity

2011

This section presents an approach that provides super resolved imaging at the center of the field of view and yet allows to see the remaining of the original field of view with original resolution. This operation resembles optical zooming while the zoomed and the nonzoomed images are obtained simultaneously. This is obtained by taking a single snap-shot and using a single imaging lens. The technique utilizes a special static/still coding element and a postprocessing algorithmic, without any mechanical movements.

Determination of 210Pb concentration in the air at ground-level by gamma-ray spectrometry

1999

Abstract 210 Pb activity concentrations in the air of Palermo were determined by γ-ray spectrometric analysis of 323 particulate samples collected in the period September 1995–December 1996. For each sample, the air filtered through a cellulose filter paper was 8600 m 3 on average. The values of the daily activity concentration of 210 Pb were ranging from 136 to 3390 μBq/m 3 .
