Opera Ludica. Alcune riflessioni sul gioco a carte nel teatro musicale fra Ottocento e Novecento
2010
The essay aims to shed light on the relationship between opera and play, focusing on the card scenes in four operatic masterpieces of the 19th and 20th centuries: "Carmen" (1875), "The Queen of Spades" (1890), "The Girl of the Golden West" (1910) and "The Rake’s Progress" (1951). In these operas, the idea of play is much more than a simple cue or thematic subject: it has a substantial and paradigmatic function, directly connected with the dramaturgic and musical architecture of the work. On the other hand, these operas share some features that can be linked to the idea of time and to the metalinguistic value of play: although play and music take place in time, they tend to annul it, thus en…
Correlating Schiff Moments in the Light Actinides with Octupole Moments
2018
We show that the measured intrinsic octupole moments of $^{220}$Rn, $^{224}$Ra, and $^{226}$Ra constrain the intrinsic Schiff moments of $^{225}$Ra$^{221}$Rn, $^{223}$Rn, $^{223}$Fr, $^{225}$Ra, and $^{229}$Pa. The result is a dramatically reduced uncertainty in intrinsic Schiff moments. Direct measurements of octupole moments in odd nuclei will reduce the uncertainty even more. The only significant source of nuclear-physics error in the laboratory Schiff moments will then be the intrinsic matrix elements of the time-reversal non-invariant interaction produced by CP-violating fundamental physics. Those matrix elements are also correlated with octupole moments, but with a larger systematic u…
Riflessioni e traiettorie di ricerca interdisciplinari sulla transizione digitale
2022
The contribution introduces the topic covered by vol. 12 of AGATHÓN through essays, studies, research and projects on Innovability©® | Digital Transition to investigate the current widespread transformation that unites dichotomies (analogue and digital), enhances oxymorons (artificial intelligence), creates paradoxes (materiality of the intangible), while indiscriminately involving architecture, humanities and social sciences, anthropology, sociology, ecology, biology, physical-mathematical sciences and neurosciences, with impacts that – while already visible today and accelerated in part by the extraordinary global health emergency – will become even more evident in the medium and long ter…
Skyrmion-number dependence of spin-transfer torque on magnetic bubbles
2015
We theoretically study the skyrmion-number dependence of spin-transfer torque acting on magnetic bubbles. The skymrion number of magnetic bubbles can take any integer value depending on the magnetic profile on its circumference and the size of the bubble. We find that the transverse motion of a bubble with respect to the charge current is greatly suppressed as the absolute value of the skyrmion number departs from unity, whereas the longitudinal motion is less sensitive.
Analysis of spectral irradiance distribution for PV applications at high latitude
2020
The spectral distribution of global tilted irradiance measured in Grimstad, Norway, is analyzed in terms of the average photon energy ( $APE$ ) blue fraction ( $BF$ ) and useful fraction ( $UF$ ). The results based on eight months of recorded data show a general shift of the $APE,\ BF$ , and $UF$ values to higher values than reference AM1.5G spectrum, with 1.63 eV, 0.45, and 0.88 being the average indices, respectively. The statistical coefficient of variation ( $CV$ ) is used to determine the variation of indices. The $CV$ for $APE,\ BF$ , and $UF$ are calculated to be 20.1%, 26.1%, and 25.7%, respectively confirming the earlier findings on $APE$ being a more accurate index for the quantif…

Spatio-temporal perturbation of the dynamics of the ferroin catalyzed Belousov-Zhabotinsky reaction in a batch reactor caused by sodium dodecyl sulfa…
2008
The effects of the anionic surfactant sodium dodecyl sulfate (SDS) on the spatio-temporal and temporal dynamics of the ferroin-catalyzed Belousov-Zhabotinsky (BZ) reaction have been studied over a wide surfactant concentration range. For the first time, investigations were performed also for unstirred systems. The presence of SDS in the reaction mixture influences the oscillatory parameters to an extent that significantly depends on the surfactant concentration. The trend of the wave speed v upon the increasing amount of SDS was found to have a maximum at [SDS] = 0.075 mol dm (-3) ( v = 0.071 mm s (-1)), after which the speed decreased to 0.043 mm s (-1) at [SDS] = 0.5 mol dm (-3), which is…
Korkeakouluohjauksen mahdollisuudet verkossa : Jyväskylän yliopiston kasvatustieteellisen tiedekunnan ensimmäisen vuoden opiskelijoiden verkkotottumu…
2011
Ohjausalalla on herätty sosiaalisen median ja verkko-ohjauksen tutkimukseen. Tutkimuksen tarve onkin ilmeinen sillä, jos ohjaus haluaa olla ihmisten elämän kannalta relevanttia, tulee sen olla valmis muuttumaan ja mukautumaan tietoyhteiskunnan vaatimuksiin. Jyväskylässä tutkitaan sosiaalisen median hyödyntämistä korkea-asteen ohjauksen ja työelämätaitojen kehittämisessä osana ESR-hanketta ”Ohjauksen ja työelämätaitojen kehittäminen korkea-asteella”. Tämän pro gradu -tutkielman aineisto on osa tätä sosiaalista mediaa ja ohjausalaa koskevaa tutkimushanketta. Tutkimuksessani pyrin kvantitatiivisesti selvittämään ESR-hankkeesta saadun aineiston avulla Jyväskylän yliopiston kasvatustieteellisen …
A New Fitness Test of Estimating VO2max in Well-Trained Rowing Athletes
2021
BackgroundThis study was designed to investigate the validity of maximal oxygen consumption (VO2max) estimation through the Firstbeat fitness test (FFT) method when using submaximal rowing and running programs for well-trained athletes.MethodsWell-trained flatwater rowers (n = 45, 19.8 ± 3.0 years, 184 ± 8.7 cm, 76 ± 12.9 kg, and 58.7 ± 6.0 mL⋅kg–1⋅min–1) and paddlers (n = 45, 19.0 ± 2.5 years, 180 ± 7.7 cm, 74 ± 9.4 kg, and 59.9 ± 4.8 mL⋅kg–1⋅min–1) completed the FFT and maximal graded exercise test (GXT) programs of rowing and running, respectively. The estimated VO2max was calculated using the FFT system, and the measured VO2max was obtained from the GXT programs. Differences between the…
Koulutuksesta työelämään : JULIET-opiskelijoiden sijoittuminen työelämään ja kokemukset JULIET-opintojen merkityksestä työn kannalta
2011
Jyväskylän yliopiston Opettajankoulutuslaitoksen JULIET‐sivuaineen tavoitteena on kouluttaa luokanopettajista monipuolisia alakoulun kielikasvattajia. Tässä tutkimuksessa selvitettiin, miten JULIET-sivuaineen suorittaneet opiskelijat ovat sijoittuneet työelämään ja miten he kokevat JULIET-opintojen sisältöjen vastaavan työelämän tarpeita. Koulutuksen merkitystä tutkittiin erikseen luokanopettajan, englannin opettajan sekä vieraalla kielellä opettavan opettajan työn kannalta. Tutkimus toteutettiin postikyselynä keväällä 2010. Kysely lähetettiin kaikille vuosina 1995–2004 JULIET-opintonsa aloittaneille sekä yhdelle vuonna 2006 aloittaneelle, jo valmistuneelle JULIET-opiskelijalle. Yhteensä lo…
