Du ciel noir à l'environnement nocturne : la construction d'un nouveau front de protection de la nature
2020
International audience; Depuis les années 1970 plusieurs domaines d’expertise scientifique ont contribué à faire émerger une nouvelle dimension de la protection de l’environnement liés aux effets dégradants de la pollution lumineuse. Cette dernière constitue en soi un objet de controverse entre sciences, notamment sur les différentes façons de la saisir et la définir en tant qu’objet et que fait. Nous retiendrons ici pour qualifier cette forme de pollution le caractère d’un excès de lumière artificielle entrainant des impacts sur les écosystèmes et sur la santé humaine.L’histoire du mouvement de lutte contre l’expansion de l’éclairage artificiel commence à être relativement connue, dans le …
Deadlock in corporate governance: Finding a common strategy for private telephone companies, 1978–1998
2017
This paper looks at how a group of small, incumbent private telephone companies complied with the international convergence of market structures. The existing research has mainly focused on large national incumbents, assuming a transition to multinational enterprise. This development process is often associated with privatisation policies and various institutional factors. The article tests these assumptions using a case study of the network of Finnish local telephone companies. It looks at the development of an interfirm network, its perspectives on the different phases of the deregulation process, and how the network tried to regenerate itself but failed to form a unified corporate struct…
New Materialist Explorations into Language Education
2023
This open access book analyzes language education through a socio-material framework. The authors revisit their position as researchers by decentering themselves and humans in general from the main focus of research activities and giving way to the materialities that are agentive but often overlooked parts of our research contexts and processes. Through this critical posthumanist realism, they are able to engage in research that sees society as an ethical interrelationship between humans and the material world and explore the socio-materialities of language education from the perspectives of material agency, spatial and embodied materiality, and human and non-human assemblages. Each chapter…
CONSIDERATIONS ON CONFLICT MANAGEMENT DURING ORGANIZATIONAL CHANGE
2021
Organizational conflict is not based on personal values; it occurs due to dynamic changes within the structure of the organization. When these dynamics are neglected, they generate conflict within the organization. Any organization reunites groups of individuals with different personalities, job outlooks, education, systems of values and different behaviors. The maintenance of a perfect harmony is hard to be achieved, conflicts being inevitable.
A revision of the structure and stratigraphy of pre-Green Tuff ignimbrites at Pantelleria (Strait of Sicily)
2013
International audience; At Pantelleria, peralkaline silicic magmas were erupted across a range of eruptive typologies and magnitudes: pyroclastic flows, Plinian to strombolian pumice fallout and lava flows. In this paper we focus on the intermediate cycle of eruptive activity which is bracketed by ignimbrite units slightly older than the two caldera collapses which marked the volcanological activity of the island. This age interval (180-85 ka) was punctuated by six ignimbrite-forming eruptions (silicic and variably peralkaline) for a cumulative erupted magma volume of approximately 6 km3 dense rock equivalent. Based on new 40Ar/39Ar (Na,K)-feldspar ages and petrographic data, we propose an …
Psihoterapeitu kreativitātes un personības iezīmju saistība ar psihoterapeitu klientu simptomu izmaiņām
2014
Psihoterapeitu kreativitātes un personības iezīmju saistība ar psihoterapeitu klientu simptomu izmaiņām Šī pētījuma mērķis ir noskaidrot vai psihoterapeitu kreativitāte un personības iezīmju izteiktība ir saistīta ar klientu problēmas simptomu izmaiņām, un kādi simptomi visvairāk samazinās. Pētījumā piedalījās 109 psihoterapeiti vecumā no 28-59 gadiem,118 citu profesiju pārstāvji vecumā no 30-57 gadiem, 45 psihoterapeitu klienti, vecumā no 18-58 gadiem. Pētījumā tika izmantoti šādi instrumenti: “Tests radošai domāšanai-attēlu veidošana” (Test of Creative Thinking – Drawing Production; TCT-DP; Urban & Jellen, 1995), Lielā Piecinieka aptauja (The Big Five Inventory; John, Donahue & Kentle, 19…
Effect of Sex, Body Mass Index and Physical Activity Level on Peak Oxygen Uptake Among 14–19 Years Old Adolescents
2020
The aim was to describe longitudinal trends in peak oxygen uptake (VO2peak) among 14- to 19-year-old adolescents in Norway, and to examine effects of sex, body mass index (BMI), and physical activity (PA) level on VO2peak during adolescence. Of 124 invited students from two lower secondary schools in Norway, 116 eighth-grade students (61 boys and 55 girls; 14 years old at baseline) volunteered to participate. The study has a longitudinal design with 6 yearly repeated measures of body height and mass, VO2peak and PA level. VO2peak allometrically scaled to body mass raised to the power of 0.67 was measured using a walking or running incremental test on a treadmill, whereas PA level was self-r…
Weathering of low-density polyethylene grafted with itaconic acid in laboratory tests
2011
Polyethylene grafted with itaconic acid was subjected to weathering under laboratory accelerated conditions. The course of the photo-oxidative degradation process of that material was studied by FTIR spectroscopy both through quantitative measurements of changes in absorbance values at selected wave numbers and through measurements of surface area values for absorption bands which were separated by means of deconvolution. The use of both those procedures of quantitative determinations resulted in a general conclusion that the oxidation process was initiated from the very first moment of irradiation, and it produced ketones, acids, esters (intramolecular and of acetate type), peracids, peres…
