The CdCl2 effects on synthetic DNAs encaged in the nanodomains of a cationic water-in-oil microemulsion
2011
The present work is dedicated to the study of the interactions of CdCl(2) with the synthetic polynucleotides polyAT and polyGC confined in the nanoscopic aqueous compartment of the water-in-oil microemulsion CTAB/pentanol/hexane/water, with the goal to mimic in vitro the situation met by the nucleic acids in vivo. In biological structures, in fact, very long strings of nucleic acids are segregated into very small compartments having a radius exceedingly smaller than the length of the encapsulated macromolecule. For comparison, the behaviour of polyGC was also studied in aqueous solutions of matched composition. The conformational and thermal stabilities of both polynucleotides enclosed in t…
Les formations professionnelles de l'enseignement supérieur en France au prisme de l'insertion et de la mobilité sociale des diplômés
2014
La professionnalisation des formations dans l'enseignement supérieur en France s'est développée ces dernières décennies avec pour objectif d'améliorer l'employabilité des jeunes diplômés dans un contexte de dégradation de leurs conditions d'insertion. À partir des trois dernières enquêtes Génération du Céreq, ce travail questionne la performance de ces filières professionnelles par rapport aux filières plus académiques de l'enseignement supérieur, en période de crise économique. Certaines formations, comme par exemple les licences professionnelles, garantissent toujours de bonnes conditions d'insertion, pour autant les effets concernant la mobilité sociale en début de carrière, sont plus nu…
Geoterminen energia ja politiikkaongelmien hallitsemisen tiedollinen haaste
2022
Ilmastonmuutoksen hillitsemiseksi energiajärjestelmän on muututtava vähähiilisemmäksi. Geoterminen energia on Suomessa ja muualla maailmassa noussut yhdeksi päästöttömäksi uusiutuvan energian muodoksi, mutta sen rakentamiseen ja käyttöön sisältyy riskejä. Tässä artikkelissa tarkastelemme geotermisen energian seismisen riskin hallintaa monitoimijaisessa verkostossa. Keskitymme siihen, millaisena eri toimijat näkevät Seismologian instituutin aseman geotermisen energian hallinnan verkostossa. Pohdimme, miten geotermisen energian seismisen riskin hallinnan kaltainen kompleksinen politiikkaongelma jäsentyy institutionaalisesti epäselvässä tilanteessa ja millaisia tietoon ja tietämiseen liittyviä…
The cross-cultural transition experience. Phenomenological analysis on a group of international students
2010
Summary This study is focused on exploration of experience of cultural transition that has lived a group of international students (European and not European) host at an Italian University during particular experiential segment marking the transition from their culture of belonging to the new social and cultural context. From an epistemological point of view that aligns with the phenomenological tradition with individual and group interviews, it was monitored with a longitudinal methodology as the representation of the transit cross-cultural adaptation to the context it emerged from the interviews are associated through the dominant narrative themes. The results show how in the early stage …
A phase I-II study on intravesical Gemcitabine in superficial bladder papillary tumors
2004
INTRODUCTION AND OBJECTIVE: The possible role of gemcitabine inintravesical therapy of superficial transitional cell carcinoma of the bladder (TCCB) has been suggested. The European Organization for Research and Treatment of Cancer Urological Group validated the use of papillary marker lesion left in the bladder after TUR as the best tool to measure the efficacy of a drug by intravesical route against TCCB. The rsults on 27 patients are herein presented. METHODS: Twenty-seven patients, with recurrent superficial TCCB (Ta-T1, G1-G2), were treated with intravesical gemcitabine for 1 to 3 papillary marker lesions (5-15 mm) left unreseacted after TUR. Twenty-one patients (78%) had recurrent tum…
Local Structure Studies of Ti for SrTi16O3 and SrTi18O3 by Advanced X-ray Absorption Spectroscopy Data Analysis
2015
Strontium titanate is a model quantum paraelectric in which in the region of dominating quantum statistics the ferroelectric instability is inhibited due to nearly complete compensation of the harmonic contribution into ferroelectric soft mode frequency by the zero-point motion contribution. The enhancement of atomic masses by the substitution of 18O for 16O decreases the zero-point atomic motion and low-T ferroelectricity in SrTi18O3 is realized. In this study we report on the local structure of Ti in SrTi16O3 and SrTi18O3 by Ti K-edge extended x-ray absorption fine structure measurements in temperature range 6 – 300 K.
Considerations regarding the Romanian fiscal and budgetary reform in accordance with the E.U. requirements
2006
The paper starts with the role of the Romanian fiscal and budgetary reform in the development and economical growth and has as purpose to emphasize the essential problems: the harmonization and fiscal coordination from the E.U. perspective; the Romanian fiscal and budgetary perspectives for period 2007-2009.
Transitions out of unemployment: The role of social networks' topology and firms' recruitment strategies
2011
In this paper we study the effects of job contact networks on out-of-unemployment transitions. We find that social connections produce sizable increases in upward mobility from unemployment and, caeteris paribus, symmetric network topologies perform better than asymmetric ones. Furthermore, in scale-free networks the probability of transitions out of unemployment increases in the exponent of the power-law degree distribution, but its value is much lower than the one attainable in Poisson random networks. In addition, and most interestingly, these results strongly depends on the different hypotheses on the firms' recruitment strategy.
Bold ambition, blunted agency? : Examining top management perspectives on a circular economy transition in Finland
2022
The circular economy is proposed as a company-driven means to further sustainability transitions. Top managers have a critical role in fostering the circular economy as they are responsible for shaping and implementing a company's sustainability strategy and performance. In this paper, we adopt a microfoundations perspective to enhance our understanding of the influence of top managers as agents of the sustainability transition to the circular economy. In a qualitative research study, we interviewed 34 top managers of Finnish companies that are actively pursuing the circular economy. The main implication of our study is in exploring the role of top managers, as they engage in actively struc…
Applying transdisciplinary sustainability transitions research in international social work doctoral training
2022
In the last 15 years, transdisciplinary research of sustainability transitions has become an increasingly powerful approach. We discuss it as a perspective for social work discipline, and as a theoretical-conceptual frame of a new international doctoral training and research programme in social work taking place in seven European countries. In our qualitative study, we investigate how the participating social work doctoral students reflect upon transdisciplinarity and understand the interconnectivity between environmental, ecological, and social sustainability transitions—which is widely recognised as a highly complex challenge of sustainability. The data used included the students’ learnin…
