Access to Higher Education: An Instrument for Fair Societies?
2019
Access to higher education (HE) has a long history. To offer a view on the current debates and worldwide issues regarding access to HE, this editorial depicts how the control of educational access has historically been used as an instrument of governance at the interface of two processes: social stratification and the territorialisation of politics. Access to HE has remained embedded in these large structural processes even though HE has expanded from a highly elitist institution into mass education systems with equity of educational opportunities having become a desirable goal across societies. Analysing these processes helps understand the complex mechanisms producing inequalities in HE t…
Effective Recovery Process of Copper from Waste Printed Circuit Boards Utilizing Recycling of Leachate
2020
AbstractThis study presents an optimized leaching and electrowinning process for the recovery of copper from waste printed circuit boards including studies of chemical consumption and recirculation of leachate. Optimization of leaching was performed using response surface methodology in diluted sulfuric acid and hydrogen peroxide media. Optimum leaching conditions for copper were found by using 3.6 mol L−1 sulfuric acid, 6 vol.% hydrogen peroxide, pulp density of 75 g L−1 with 186 min leaching time at 20°C resulting in complete leaching of copper followed by over 92% recovery and purity of 99.9% in the electrowinning. Study of chemical consumption showed total decomposition of hydrogen pero…
A sense of spacing: Toward a diffractive reading of organizational space
2022
This article explores how a diffractive methodology can enrich research on organizational space and the senses. Through the creation of interferences, a diffractive methodology directs attention to how differences in sensing are created in the ongoing production of space and what the effects of these are. By using examples from an ethnographic study of the Hub, a university-based entrepreneurship space designed to invoke positive “buzz”, the article illustrates how a diffractive methodology allows for the exploration of the sensory design of space and how it governs the possibilities of sensing among participants. The article contributes to organizational research by demonstrating how a di…
Effets de quartier, effet de département : discrimination liée au lieu de résidence et accès à l'emploi
2013
L’objet de cette étude est de mesurer la discrimination à l’embauche à l’encontre des jeunes en Ile-de-France en raison du lieu de résidence en considérant plusieurs échelles spatiales de façon à distinguer l’effet de la réputation du département (Paris et la Seine-Saint-Denis), celui de la localité et celui du quartier. L’évaluation est réalisée sur données expérimentales auto-construites de testing selon un protocole permettant d’examiner les effets propres à chacune de ces trois échelles sur l’accès à l’emploi ainsi que leurs effets cumulés. On s’intéresse aux discriminations pour deux professions en tension du secteur de la restauration pour laquelle les discriminations devraient a prio…
Developing mixed methods research in sport and exercise psychology: potential contributions of a critical realist perspective
2020
Notwithstanding diverse opinions and debates about mixing methods, mixed methods research (MMR) is increasingly being used in sport and exercise psychology. In this paper, we describe MMR trends within leading sport and exercise psychology journals and explore critical realism as a possible underpinning framework for conducting MMR. Our meta-study of recent empirical mixed methods studies published in 2017–2019 indicates that eight (36%) of the 22 MMR studies explicitly stated a paradigmatic position (five drew on pragmatism, two switched paradigms between qualitative and quantitative elements of the study, and one was situated in relativist-interpretivism). The remaining 14 (64%) studies d…
Elisabeth on Free Will, Preordination, and Philosophical Doubt
2021
Elisabeth is widely known as a critic of René Descartes' account of mind--body interaction and scholarly interpretations of her view on the will most often pose the question about the freedom of the will in relation to bodily impulses such as the passions. This chapter takes a different perspective and focuses on the problem of the compatibility of free will and providence, as it is discussed in a sequence of six letters that Elisabeth and Descartes wrote between September 1645 and January 1646. The chapter focuses on this specific metaphysical problem in order to ask what Elisabeth's remarks on the topic can tell about her general philosophical method as well as about her particular philos…
Reflections on developing indicators for campus sustainability from a fragility perspective
2016
Cel: Tekst streszcza dyskusję przeprowadzoną podczas warsztatów na temat „Metodologia oceny zrównoważonego rozwoju kampusu z perspektywy antykruchości wielopoziomowej” zorganizowanych przez Wyższą Szkołę Bankową we Wrocławiu w piątek, 13 maja 2016 r. i zawiera informacje zwrotne uczestników tej dyskusji, które pozostawili w formie notatek. Prezentuje ponadto wynik procesu interakcji i refleksji autorów na temat metodologii i oceny zrównoważonego rozwoju kampusu z wykorzystaniem perspektywy kruchości. Metoda badawcza: Artykuł zawiera informacje zwrotną opartą na doświadczeniu i pomysłach badawczych studentów z Gruzji, Niemiec, Kazachstanu i Litwy. Dyskusja najpierw przebiegała w grupach foku…
Immunoaffinity purification and characterization of mitochondrial membrane-bound D-3-hydroxybutyrate dehydrogenase from Jaculus orientalis.
2008
Abstract Background The interconversion of two important energy metabolites, 3-hydroxybutyrate and acetoacetate (the major ketone bodies), is catalyzed by D-3-hydroxybutyrate dehydrogenase (BDH1: EC 1.1.1.30), a NAD+-dependent enzyme. The eukaryotic enzyme is bound to the mitochondrial inner membrane and harbors a unique lecithin-dependent activity. Here, we report an advanced purification method of the mammalian BDH applied to the liver enzyme from jerboa (Jaculus orientalis), a hibernating rodent adapted to extreme diet and environmental conditions. Results Purifying BDH from jerboa liver overcomes its low specific activity in mitochondria for further biochemical characterization of the e…
FROM SURVEY TO MODEL, AND RETURN. THE CASE OF THE PARMA BAPTISTERY
2019
Abstract. Although this is not always the common practice, the survey should be an essential preliminary stage to any operation of restoration, enhancement and promotion of cultural heritage. Today, various surveying techniques make it possible to collect large amounts of data quickly and to provide a complete three-dimensional representation of extremely complex artefacts. In fact, 3D models allow a much richer description than traditional 2D representations. However, these survey techniques (laser scanner and photogrammetry above all) necessarily imply that the data that must be elaborated during the processing phase increase dramatically. It is therefore essential to identify methods and…
INTEGRATED SURVEY FOR ARCHITECTURAL RESTORATION: A METHODOLOGICAL COMPARISON OF TWO CASE STUDIES
2016
Abstract. A preliminary survey campaign is essential in projects of restoration, urban renewal, rebuilding or promotion of architectural heritage. Today several survey techniques allow full 3D object restitution and modelling that provides a richer description than simple 2D representations. However, the amount of data to collect increases dramatically and a trade-off between efficiency and productivity from one side and assuring accuracy and completeness of the results on the other must be found. Depending on the extent and the complexity of the task, a single technique or a combination of several ones might be employed. Especially when documentation at different scales and with different …
