The development and application of self-cleaning treatments on historical and architectural stone surfaces could be a significant improvement in conservation, protection and maintenance of Cultural Heritage. In this paper, a TiO2-based coating has been investigated in order to evaluate its possible use as a self-cleaning treatment. This coating was obtained by a sol-gel and a hydrothermal (134 °C) processes and then it was applied on travertine (a limestone often used in historical and monumental buildings) in two ways, obtaining a single-layer and a three-layer treatment, respectively. In order to verify its potential use in the field of Cultural Heritage, the maintenance of appearance properties of the treated travertine surfaces was monitored by colour and gloss analyses. Besides, de-pollution and soiling removal tests were carried out under ultraviolet-light exposure to evaluate photo-induced effects and self-cleaning efficiency. Results seem to allow the use of TiO2-based treatments on historical and architectural surfaces made up by travertine, where de-pollution and self-cleaning photo-induced effects are well evident, maintaining their original visual appearance. Anyway, before applying TiO2-based coatings as conservative treatments, further tests are needed especially on their durability, that is mandatory for Cultural Heritage applications. On-site test in an urban environment and accelerated test by weatherometer are currently under way. 相似文献

This is the fourth in a series of articles exploring international trends in health science librarianship in four Southern European countries in the first decade of the 21st century. The invited authors are from Greece, Italy, Spain and Portugal. Future issues will track trends in Latin America and Central Europe. JM 相似文献

The article presents a quantitative and qualitative analysis that identifies the most important lifestyle factors of an independent population of 50-75 years living at home and in a variety of middle-sized towns in the Marche Region (Italy). The first step was an investigation of multiple associations among state of health, socioeconomic variables, and lifestyle. After studying the set of variables defining lifestyle, we proceeded to identify the most important ones in order to select a group of elderly with a "correct" lifestyle. The principal outcome concerns the overwhelming role played by the subjective perception of aging. It is, therefore, necessary for social policies to concentrate on the importance of promoting educational campaigns for the achievement of successful aging, stressing the value of both personal well-being and socializing activities. 相似文献

In 2005 a survey was used to investigate social norms and attitudes of Viennese high school students (14–20 years, n = 340) toward organic products. Young people, who already participate in household decisions and consume organic products, have not yet been recognized sufficiently in research. The Theory of Reasoned Action and discriminant analysis are used to explore relations of a number of variables and the complex field of factors influencing Viennese high school students’ shopping behavior when shopping for organic products. Key findings include the importance of primary socialization in forming social norms and shaping behavior. Surprisingly, knowledge of organic products does not explain students’ self-reported shopping behavior when shopping for organic products. Cultural patterns seem to be far more useful to predict behavior and attitudes toward organic products. 相似文献

In this paper, we provide a comprehensive picture of social selectivity in higher education in Italy by focusing on enrolment and two alternative indicators of success: retention and timely completion. The existing literature has shown that young individuals of disadvantaged backgrounds have lower enrolment probabilities and higher chances of withdrawal. This paper analyses the size and features of this cumulative disadvantage, shaping the chances of high-school leavers of eventually attaining the university degree. We analyse whether social background inequalities are stronger at enrolment or at later outcomes, and how these inequalities vary with previous schooling experience. We confirm previous evidence that disadvantaged groups with respect to enrolment are also disadvantaged on persistence, add new findings on timely completion and show that cumulative inequalities are very strong. Inequalities are strongest among students holding technical and vocational high-school qualifications and weakest among well-performing students from lyceums. In addition, we examine the role of labour market conditions and whether they explain geographical differences. Enrolment, retention and timely completion probabilities appear negatively related to local youth unemployment rates, suggesting that with poor labour market prospects, individuals lose motivation and reduce their engagement in education. 相似文献

This paper investigates the interaction between technological and organizational parameters. Recent studies have been focused on the information and communication impact on organizational parameters, owing to the growing need to acquire and process information. We focus on the impact of the content management system on publishing firms and through the study of ten Italian cases we identify the socio-technical context which favor the adoption of technology as well as the organizational parameters influenced by the technology use. 相似文献

The history of relationships between Roma/Sinti and non-Roma/non-Sinti is marked and crossed by negative features and trails: anti-ziganismus, asymmetric power relationships within institutions and the absence of social justice in the school toward Romani minorities. This article—starting from the negative aspects of the inter-ethnic relations between Roma and majority societies—on the contrary explores the positive features of these relationships, through a long-lasting ethnographic research and through the intimacy and friendship of the author with the research’ subjects. Without the deep connection and friendship established through the ethnographic relationship, these “positive” outcome would have remained eluded. The article will highlight how long-lasting ethnographic research is essential for the research’ outcomes, but also for the improvement of social justice within institutions, impairing the asymmetric power relationships between non-Roma majority and Roma/Sinti minorities. Indeed, long-lasting ethnographic research, ethnographic restitution and an “engaged anthropology” approach are central issues for intercultural education both within institutions, such as school, and in less formal contexts, as urban quarters, low-income flats and extra-school contexts of multicultural societies. 相似文献

This contribution looks at the competency development during teacher training and entry into work. The multi-perspective research design makes it possible to collate data at five stages within this transition process: at the start (t1), in the middle (t2) and on completion (t3) of teacher training for primary school level (year 1–6) student teachers in two education colleges in Switzerland, as well as novice teachers at the start (t4) and on competition (t5) of their first year of work. The data covers eleven topic areas. This paper will present findings of data analysis for two of these topic areas for all five stages of measurement: (a) knowledge of lesson planning was captured using case vignettes and (b) teaching practice during the study program and in the first year of work was recorded on video. The same data was collated from the teaching staff involved in the practical training of the student teachers. The statements on the case vignettes were studied using content-analysis. The lesson videos were analyzed using low-inference coding for the visible occurrences during teaching and with a high-inference rating on the quality of the lessons. The results, including those for a comparison of student teachers and novice teachers with practical teacher training staff, give insights into the effectiveness of teacher training and the impact of practical experience in the first year of work on knowledge of how to plan lessons and on the form and quality of teaching. Overall, the new training at both education colleges can be given a pleasingly positive appraisal in terms of professionalization. It is, however, also possible to recognize where and to what extent a need for further developing the standard of professionalization of teaching still exists. 相似文献
