Study of Even Gd Nuclei by Decay of Oriented Tb, With Analysis by Simple Boson Models
1983
We have studied low-spin states of 150,152,154,156Gd by nuclear orientation of β-decaying Tb in a Gd host. Especially by means of multipole mixing ratios, including E0/E2, we have checked and revised spin-parities and assignments to (quasi) rotational ground, β and γ bands. For 150Gd we propose the new interpretation 1207.2 keV (0β+), 1518.5 keV (2β+), 1700.1 keV (4β+), 1430.5 keV (2γ+), 1988.0 keV (3γ+), 2080.0 keV (4γ+). For 152,154,156Gd we find agreement with recent literature. Our comparison with theory includes available data on 158,160Gd and on states up to 10g+, 10β+, 7γ+. We review our previously proposed "projection model", which is basically of the Bohr-Mottelson geometrical type…
A First Assessment of the Corrections for the Consistency of the IAU2000 and IAU2006 Precession-Nutation Models
2020
The Earth precession-nutation model endorsed by resolutions of each the International Astronomical Union and the International Union of Geodesy and Geophysics is composed of two theories developed independently, namely IAU2006 precession and IAU2000A nutation. The IAU2006 precession was adopted to supersede the precession part of the IAU 2000A precession-nutation model and tried to get the new precession theory dynamically consistent with the IAU2000A nutation. However, full consistency was not reached, and slight adjustments of the IAU2000A nutation amplitudes at the micro arcsecond level were required to ensure consistency. The first set of formulae for these corrections derived by Capita…

Relación entre el consumo de sustancias tóxicas y el uso del preservativo
2019
En los últimos años ha habido un repunte en las infecciones de transmisión sexual (ITS). Tradicionalmente, se asociaban las ITS a ciertos colectivos. Sin embargo, se observa que esta acentuación se da en diferentes grupos poblacionales, y es debida principalmente a las conductas sexuales de riesgo que se realizan, las cuales son exacerbadas por ciertos factores, como el consumo de sustancias tóxicas, la baja percepción de riesgo o la búsqueda de sensaciones sexuales. El principal objetivo es comprobar la relación existente entre el consumo de sustancias y el uso del preservativo en distintas prácticas sexuales. Como objetivos secundarios, se estudiarán estas mismas relaciones en función del…
Pregnenolone sulphate improves memory processing in early-handled female rats
2013
Early life experiences lead to sex-specific behavioural and neurochemical changes in adulthood. Indeed, early handling enhances learning and memory in male rats (Cannizzaro et al., 2005), whereas it impairs learning performance in female adult rats, a finding that has been correlated to decreased nitric oxide (NO) production in the hippocampus (Noschang et al., 2010). Pregnenolone sulfate (PREGS) is considered as one of the most potent memory-enhancing neurosteroids, since its activity as a potent positive modulator of N-methyl-d-aspartate receptors (NMDARs) and a negative modulator of gamma-aminobutyric acid(A) receptors (GABA(A)Rs) (Vallée et al., 2001). Given these premises, this study a…
The role of negative and positive forms of power in supporting CSR alignment and commitment between large firms and SMEs
2018
Do large firms exert power to shape the CSR behavior of their SME partners?” We answer this question by proposing a model built on the stakeholder theory and the shareholder theory, and go on to explain how this impact influences the commitment of the SME towards their large partner. The model highlights the central role that different forms of power exercised by the large firm play in the process. A survey of 291 SMEs confirms the key hypotheses, including the mediating role of reward power. The effects of coercive power are noteworthy and they illustrate the complex and competing forces at play in influencing CSR behavioral change in SMEs. The research makes a novel contribution to practi…
The Effect of Perceived Corporate Competencies on Onsumer Based Brand Equity: A Comparison between Domestic and Foreign Markets
2015
In this paper, the authors develop a model to explain the cross-cultural influence of perceived corporate competencies on attitude formation towards the brand’s product categories and its impact on consumer based brand equity. Results indicate that some competencies have a transnational effect in several product categories, whereas several corporate competencies are identified to influence perception of product categories depending on the market.
Importance of the Motivational Climate in Goal, Enjoyment, and the Causes of Success in Handball Players
2017
The purpose of the study is to examine the effects of the motivational climate created by the coach and perceived by a group of young handball players on their goal orientations, their beliefs regarding reasons for success and their self-satisfaction. The study participants were 159 young handball players. Players were administered a battery composed of tests to measure the above-mentioned motivational constructs. Results showed that a perceived mastery-oriented motivational climate was positively related to a task-centered goal orientation, enjoyment, and a belief that success may be achieved through effort. In contrast, a perceived performance-orientated training climate was linked to an …
The associations between seventh grade Finnish students’ motivational climate, perceived competence, self-determined motivation, and fundamental move…
2009
The aim of the study was to investigate the relationships between motivational climate, perceived competence, self-determined motivation towards physical education (PE) and the fundamental movement skills of Finnish secondary school students. A sample of 370 seventh-grade PE students (girls n = 189; boys n = 181; mean age = 13.08; SD = 0.25) completed measures pertaining to motivational climates, perceived competence, regulation of motivation, and fundamental movement skills. Path analysis revealed results generally consistent with the theoretical tenets of the self-determination and the achievement goal theories by demonstrating that a task-involving motivational climate influenced percei…
