Solar radiative effects of a Saharan dust plume observed during SAMUM assuming spheroidal model particles
2011
The solar optical properties of Saharan mineral dust observed during the Saharan Mineral Dust Experiment (SAMUM) were explored based on measured size-number distributions and chemical composition. The size-resolved complex refractive index of the dust was derived with real parts of 1.51–1.55 and imaginary parts of 0.0008–0.006 at 550 nm wavelength. At this spectral range a single scattering albedo ω o and an asymmetry parameter g of about 0.8 were derived. These values were largely determined by the presence of coarse particles. Backscatter coefficients and lidar ratios calculated with Mie theory (spherical particles) were not found to be in agreement with independently measured lidar data.…
Specificity of weightlifting bench exercises in kayaking sprint performance: A perspective for neuromuscular training
2022
Several studies showed significant differences between bench lift exercises without investigating which is more related, in biomechanical and neuromuscular terms, to improve the sprint flatwater kayak performance. This study aims to compare the power-load and velocity-load neuromuscular parameters performed in prone bench pull (PBP), and bench press (BP) exercises to identify which of them meet the gesture specificity in sprint flatwater kayak performance. Ten elite kayakers participated in this study. Power-load, velocity-load relationships, the maximum dynamic strength, and the kayak sprint performance test were assessed. The power-load and velocity-load relationships showed significant d…
Teaching specialised vocabulary in a communicative way
2017
Työn tarkoituksena on tutkia ammatillisen erikoissanaston opettamisen kysymyksiä tavoitteena laatia sopivaa opetusmateriaalia intensiivikurssille, joka on tarkoitus pitää Ikean myyntihenkilökunnalle. Sanaston opettamisen lisäksi kurssin toisena ja yhtä tärkeänä tavoitteena on parantaa työntekijöiden englannin kielen puheen sujuvuutta ja sitä kautta itseluottamusta käyttää englantia työssä. Työ koostuu teoriaosasta, jossa haetaan sopivimpia lähestymistapoja ja opetusmenetelmiä ammattisanaston opettamiseksi ja suullisen kielitaidon parantamiseksi, sekä opetusmateriaalipaketista, johon on koottu valikoima sopivia harjoituksia ja tehtäviä, jotka perustuvat teoriaosassa valitulle teoreettiselle …
Enablers of and constraints on employees' information sharing on enterprise social media
2020
PurposeThe purpose of this study is to investigate the various enablers of and constraints on employees' information sharing on an enterprise social media platform. It draws on two theoretical perspectives, communication privacy management theory and the technology affordance framework, as well as on empirical data in an attempt to paint a comprehensive picture of the factors shaping employees' decisions to share or not share information on enterprise social media.Design/methodology/approachThis qualitative field study is based on semi-structured interviews and enterprise social media review data from a large Nordic media organization.FindingsOn an enterprise social media platform, privacy …
Organizing for collaboration in simulation-based environments : an affordance perspective
2023
Extant research has identified the significance of technological affordances in computer-supported learning environments. However, until recently, there is scarcely empirical research on affordances for organizing collaboration in these learning environments. To address this gap, this study empirically examines affordances for organizing collaboration in a simulation-based learning environment. We focus, in particular on understanding how the organizing affordances of the learning environment are perceived and employed by the learners during a simulation-based learning task. The study was executed among 177 undergraduate higher education (HE) business students from 10 universities in Belgiu…

Il Problem Based Learnig (PBL) come strumento di orientamento nella scuola secondaria di primo grado
2022
La scuola costituisce indubbiamente un luogo privilegiato di inserimento sociale, di partecipazione e di confronto e allo stesso tempo per imparare ad orientarsi e in cui gli alunni vengono incoraggiati attivamente al ragionamento e alla risoluzione dei problemi ricavando e attingendo in modo autonomo a tutte le fonti informative necessarie a tale scopo. L’ipotesi di ricerca da cui lo studio parte è che la metodologia didattica dell’apprendimento per problemi (PBL) sia efficace nello sviluppo di competenze strategiche (problem-solving, decision-making) e, pertanto, possa essere applicata nelle attività di orientamento. L’attività di Problem-Based Learning è stata proposta a 98 docenti di s…
Oxygen uptake, acid-base balance and hormonal responses in maximal 300 - 400 m running in child, adolescent and adult athletes
2013
Vilmi, Nikke (2013). Oxygen uptake, acid-base balance and hormonal responses in maximal 300 - 400 m running in child, adolescent and adult athletes. Department of Biology of Physical Activity, University of Jyväskylä, Master's thesis, Science of Sport Coaching and Fitness Testing, 55 pp. The 400 m sprint demands both aerobic and anaerobic energy systems. During the race the acid-base balance of the body is disturbed and that has effects on the oxygen uptake. The purpose of this study was to investigate the oxygen uptake and acid-base balance during and after the maximal anaerobic running test in child (300 m), adolescent (350 m) and adult (400 m) athletes. Furthermore, the aim was also to d…
Molluscan antimicrobial peptides, a review from activity-based evidences to computer-assisted sequences
2011
Antimicrobial peptides (AMPs) represent the most universal immune effectors. Molluscs constitute the second largest animal phylum, after Arthropods, in term of number of species. Only a negligible number has been investigated regarding AMPs. The choice of the species to be studied relied on their economical importance and availability. First studies on molluscan AMPs dated from 1996 and were based on biological activities of biochemical-purified fractions. Such approach released all the original structures we know, with biological activity sometimes different from one isoform to another. Then, molecular biology techniques were applied to molluscan AMPs starting in 1999. Complete screening o…
Sperimentazione di una procedura per la creazione di un atlante digitale per la documentazione dei soffitti lignei dipinti di Sicilia
2021
The naves of churches and the halls of noble palaces. The paintings that decorate these ceilings are precious evidence of the wide cultural connections that linked Sicily to Europe and to the Mediterranean area. The paper reports the results of research aiming at the development of a workflow for the creation of a digital atlas of these ceilings. Digital representation overcomes one of the main obstacles to the study, the preservation and the dissemination of these works of art, i.e. the traditional dichotomy between photographic images and drawings. The chosen case study is the ceiling that covers the main hall of the Steri in Palermo, a 14th-century palace that today hosts the offices of …
