Performing arts and mediation technology in the period of lockdown
2021
Advancements in digital technologies have become novel ways to enrich communication, expression, and transmission of arts knowledge. Technology is increasingly implemented in the performance space, as a source of inspiration for artists. Especially in this period of lockdown, mediation technology has turned out to be an essential tool for different aspects of social life, as in performing arts. With venues, schools and artistic activities closed, performers, students and spectators have been obliged to keep connecting in remote conditions. This article wants to retrace the aesthetic impact of mediation technology in performing arts during this period of lockdown by focusing on the aspects t…
Towards Automatic Testing of Reference Point Based Interactive Methods
2016
In order to understand strengths and weaknesses of optimization algorithms, it is important to have access to different types of test problems, well defined performance indicators and analysis tools. Such tools are widely available for testing evolutionary multiobjective optimization algorithms. To our knowledge, there do not exist tools for analyzing the performance of interactive multiobjective optimization methods based on the reference point approach to communicating preference information. The main barrier to such tools is the involvement of human decision makers into interactive solution processes, which makes the performance of interactive methods dependent on the performance of huma…
An Artificial Decision Maker for Comparing Reference Point Based Interactive Evolutionary Multiobjective Optimization Methods
2021
Comparing interactive evolutionary multiobjective optimization methods is controversial. The main difficulties come from features inherent to interactive solution processes involving real decision makers. The human can be replaced by an artificial decision maker (ADM) to evaluate methods quantitatively. We propose a new ADM to compare reference point based interactive evolutionary methods, where reference points are generated in different ways for the different phases of the solution process. In the learning phase, the ADM explores different parts of the objective space to gain insight about the problem and to identify a region of interest, which is studied more closely in the decision phas…
Repositioning teachers as assessors : Compromised aspirations and contested agency
2021
The global trend to emphasise assessment for learning brings up the issue of repositioning teachers in assessment. The contemporary curricular policy reforms encourage teachers to take an agentic role in assessment, but multiple dimensions of the environment affect its realisation. Drawing on an ecological approach to teacher agency, this empirical study investigated how Korean secondary English teachers (KSETs) perceive and enact their own teacher agency in assessment within the ecosystem of Korean education. The dataset for the study comprises semi-structured interviews with 15 KSETs. The interview questions involved the main themes such as personal experiences over the life course regard…
Le Vin & la Musique. Accords et désaccords
2018
International audience; Bacchus est le dieu de l'ivresse, des plaisirs sensuels, de la fertilité comme de l'inspiration. Son cortège est animé par des satyres et des ménades dont les activités sont associées à la danse, à l'amour et la musique. L'allégorie de la musique est elle aussi fréquemment associée à l'amour, à la sensualité et au vin. Depuis l'Antiquité, cette double inspiration mythique et symbolique est au coeur d'innombrables oeuvres plastiques et visuelles, mais aussi d'objets utilitaires au décor festif, d'oeuvres musicales ou chorégraphiques et d'instruments de musique. À toutes les époques, la fête, le banquet et la taverne ont associé le vin et la musique dans tous les milie…
Photosynthesis and Transpiration in Damaged and Undamaged Spruce Trees
1996
Abstract The investigations presented here focus on the CO2/H2O gas exchange in damaged and undamaged spruce trees while using open-air measurements as well as measurements under defined conditions in the laboratory. The studies were performed at two different sites in the Hunsrück and the Westerwald mountains. In the laboratory the CO2/H2O gas exchange was measured on detached branches under controlled conditions in the course of two years. CO2 saturation curves were also generated. In addition CO2 compensation points were deter mined employing a closed system. In the natural habitat diurnal course measurements of photosynthesis and transpiration as well as light-saturation curves for pho…
Die Wirkung unterschiedlicher Lichtintensitäten während der Anzucht auf die CO2-Kompensationslage, die Glykolsäure-Oxidase- und Ribulosebiphosphat-Ca…
1978
Summary Sinapis alba (white mustard) plants were grown under conditions of strong (100 W · m -2 ) and weak (3 W · m -2 ) light and the effect of the light intensity during growth on the CO 2 -compensation point and the activities of glycolic acid oxidase and ribulose bisphosphate carboxylase were studied. The CO 2 -compensation concentration was determined according to two methods: firstly in a closed system with an infrared CO 2 -analyzer, and secondly according to the curve of net photosynthesis as a function of C0 2 -concentration over the range of 400 vpm CO 2 to the CO 2 -compensation point (Fig. 4). The intensity of light during growth was observed to exert an unmistakable effect on t…
Measurement of Photosynthesis and Transpiration in Spruce Trees with Various Degrees of Damage
1987
Summary In the context of a project on physiological and biochemical characterization of spruce with different degrees of damage, the C02 and H2O gas exchange of 22-year-old spruce from a location in the Hunsru.ck (West Germany) were measured in summer 1985. The measurements were carried out on shoots from 1984 and were set up as a pair comparison, i.e. the measurement data of a tree with symptoms of damage were always compared with a tree in the immediate vicinity which phenotypically showed less damage. Diurnal course measurements in the open air revealed a marked reduction of photosynthesis depending on the degree of damage of the trees. If one plots photosynthetic rate against light int…
Acetaldehyd als Indicator f�r die Regulation von Atmung und G�rung bei der aeroben Verg�rung von Glucose durch Saccharomyces cerevisiae
1971
Wahrend der aeroben Vergarung von Glucose wurde die Konzentration von Acetaldehyd im Garmedium uber den gesamten Garablauf bei mehreren Stammen von Saccharomyces cerevisiae verfolgt. Die Aldehydkonzentration weist bei Glucosekonzentrationen zwischen 5 und 20% zwei Maxima auf. Damit ist der Konzentrationsverlauf von Acetaldehyd aerob wesentlich anders als bei der anaeroben Garung, mit nur einem meist niedrigen Maximum. 10-3 M Azid hemmt die Bildung von Acetaldehyd ganz oder weitgehend. Das deutet auf die Funktion bzw. Synthese der Cytochrome, die in Gegenwart von Sauerstoff offensichtlich auch bei hohen Glucosekonzentrationen nicht vollstandig reprimiert werden. Der durch die Atmung bedingte…

EFFETTI DI UN PROGRAMMA DI ESERCIZIO FISICO SUL GRADO DI REATTIVITÀ BRONCHIALE NEGLI ASMATICI N. Scichilone 1, G. Morici 2, D. Zangla 3, R. Arrigo 1, I. Cardillo 1, V. Bellia 1, M.R. Bonsignore 1 1 DIBIMIS, Università degli Studi di Palermo, 2 BIONEC, Università degli Studi di Palermo, 3 DISMOT, Università degli Studi di Palermo SCOPO DEL LAVORO: Il nostro gruppo ha recentemente dimostrato che il grado di reattività bronchiale in assenza di respiri profondi si riduce negli individui sani in seguito ad un intenso programma di allenamento. Nello studio corrente, abbiamo valutato se un simile effetto benefico dell’esercizio fisico potesse realizzarsi negli asmatici. MATERIALI E METODI: Nove as…
