Effects of protein supplementation in fitness world: A 12-week cross-over studio

2020

The aim of this project was to evaluate the effect of isolated protein supplementation in young amateur athletes. Sixteen subjects aged between 20 and 30 were recruited for this study. Before to start sports performance was assessed at T0, in all subjects, using physical performance test and evaluated body composition. Therefore, the subjects were randomly assigned in two groups (group A and B) of 8 subjects each. The group A start to intake 30 g of protein powder diluted in water after each training session (3 times a week) for six weeks (T0) whilst the group B was the placebo. After 6 weeks (T1), the measurement were repeated for all subjects and the group A became placebo and the group B…

The impact of fairness on the performance of crowdsourcing an empirical analysis of two intermediate crowdsourcing platforms

2016

This research aims to investigate mechanisms available to the seeker to encourage participation of solvers to a challenge. We hypothesize that specific crowdsourcing mechanisms, reducing the information asymmetry of solvers on the challenge, increase solvers’ perception of procedural and distributive fairness and incentive their self-selection process. Moreover, posing problem in an ‘open’ manner exposes seekers to possible opportunism risks. Thus, seekers utilize many safeguard contractual mechanisms to mitigate these risks and protect the information shared in a challenge. By using data from two intermediate crowdsourcing pltaforms, we provide that safeguard mechanisms may have a drawback…

LEVERAGING CROWDSOURCING COMMUNITY TO INCREASE THE CHANCES OF WINNING CONTESTS: A SIGNALLING THEORY APPROACH

Media-induced recovery: The effects of positive versus negative media stimuli on recovery experience, cognitive performance, and energetic arousal.

2017

Recent research has demonstrated that the use of hedonically positive interactive media content contributes to the satisfaction of recovery needs and is associated with recovery outcomes such as higher levels of cognitive performance and increased energetic arousal. The recovery effects of noninteractive media stimuli as well as of media content with negative affective valence, however, are less clear. The present investigation addressed this limitation of prior research on

School performance of children from monogamous and polygamous families in Nigeria

2014

Scholastic success of Nigerian children coming from polygamous ( n = 50) and monogamous families ( n = 156) was compared. No differences between the two groups were observed across background variables of demographics, parental education and occupation, or family support for schooling. There were no differences in the Junior Secondary School Entrance Exam scores between the groups. However, children from polygamous families reported more difficulties in mathematics and English than their counterparts from monogamous families. The findings are discussed in relation to previous research.

Città Invisibili of Teatro Potlach: A Journey to Rediscover Our Cultural Heritage

2017

Città Invisibili is a multidisciplinary art project made by the Italian company Teatro Potlach. Compared to the canonical theatrical performances, Città Invisibili, being in its essence a site-specific performance, interacts with the place where it grows. With the project, the Italian group builds next to the existing space of the place (physical space and memory space) other two spaces, the space of the staging and the space of the performer, using different materials, in particular cloths and video projections. Moreover Teatro Potlach conducts a historical, anthropological and social research trying to bring out the latent memory of places. All these interventions bring out from the place…

Abstract Information technology (IT) engagement is defined as a need to spend more time using IT. Practice-based examples show that IT engagement can have adverse effects in organizations. Although users can potentially get more work done through IT engagement, observations show that the users might jeopardize their well-being and hamper their work performance. We aimed to investigate this complexity in the research on IT engagement by examining its potential antecedents and outcomes in organizations. Considering the potentially mixed outcomes, we developed a model to examine the effects of IT engagement on personal productivity and strain. We also aimed to explain the antecedents of IT eng…

Electron-interacting dark matter: Implications from DAMA/LIBRA-phase2 and prospects for liquid xenon detectors and NaI detectors

2019

We investigate the possibility for the direct detection of low-mass (GeV scale) weakly interacting massive particles (WIMP) dark matter in scintillation experiments. Such WIMPs are typically too light to leave appreciable nuclear recoils but may be detected via their scattering off atomic electrons. In particular, the DAMA Collaboration [R. Bernabei et al., Nucl. Phys. At. Energy 19, 307 (2018)] has recently presented strong evidence of an annual modulation in the scintillation rate observed at energies as low as 1 keV. Despite a strong enhancement in the calculated event rate at low energies, we find that an interpretation in terms of electron-interacting WIMPs cannot be consistent with ex…

A functional variant of the serotonin transporter gene (SLC6A4) moderates impulsive choice in attention-deficit/hyperactivity disorder boys and sibli…

2011

Item does not contain fulltext BACKGROUND: Impulsive drive for immediate reward (IDIR) and delay aversion are dissociable elements of the preference for immediate over delayed rewards seen in attention-deficit/hyperactivity disorder (ADHD). We hypothesized that IDIR would be associated with dopamine regulating genes and delay aversion would be associated with serotonin-regulating genes. METHODS: Impulsive drive for immediate reward and delay aversion were measured in 459 male children and adolescents (328 ADHD and 131 unaffected siblings) with a laboratory choice task. The sample was genotyped for the 5HTT (SLC6A4) promoter serotonin-transporter-linked polymorphic region polymorphism and a …

Chromatographic fingerprint, antioxidant activity, and colour characteristic of polish goldenrod (Solidago virgaurea L.) honey and flower

2018

In recent times, the nutraceutical and pharmaceutical interest in honey due to its well-known health properties has increased. Consumers need clear and precise information, so that they can make informed choices about their diet and the foods they buy. Therefore, gas chromatography–mass spectrometry (GC–MS) and high-performance liquid chromatography with a photodiode array detector (HPLC-PAD) was revealed a general characteristic fingerprint of polish monofloral goldenrod honey and flowers. In addition, high-performance thin-layer chromatography (HPTLC) has proven to be a useful tool for determining similarity patterns of common bands among honey from the same floral source and thus can be …
