Knowledge space oddity: How to increase the intensity and relevance of the technological progress of European regions     

Roberta Apa  Ivan De Noni  Luigi Orsi  Silvia Rita Sedita 《Research Policy》2018,47(9):1700-1712

This work contributes to previous research on the relationship between specific features of a regional knowledge space and the technological progress of the region. In particular, the main element of originality of this work is to have singled out the determinants of the technological progress intensity and relevance. We acknowledge the importance of knowledge assets for new knowledge production, and we identify path-dependent processes that allow a region to become increasingly competitive in terms of innovation potential. In particular, adopting an evolutionary view of regional development, we describe the regional knowledge space through four crucial characteristics: 1) technological knowledge base, 2) technological cumulativeness, 3) technological diversification, and 4) technological relatedness. We then measure to what extent each of the knowledge space’s characteristics differently affects the technological progress intensity and relevance of the region. A longitudinal study of 269 European regions over the period 1996–2012 was organized using data from REGPAT and Eurostat databases. Results show that technological relatedness affects positively both the intensity and relevance of the technological progress of European regions and that the other components of the knowledge space show a different impact on the two features of the technological progress. Finally, implications for EU policies supporting and stimulating regional technological progress are discussed.  相似文献   

Reconstructing the internship program as a critical reflexive practice: the role of tutorship     

Silvio Ripamonti  Laura Galuppo  Andreina Bruno  Silvia Ivaldi  Giuseppe Scaratti 《Teaching in Higher Education》2018,23(6):751-768

Critical reflexivity has been acknowledged as fundamental in higher education. For facing complex situations in turbulent environments, students nowadays need not only to be taught technical knowledge, but also to be helped develop “relevant” learning for their future professional practice. In recent years, scholars have concentrated on what makes the internship experience a successful opportunity for the parties involved, and have also discussed the crucial role of a mentor/tutor in sustaining relevant and effective learning. However, the specific conditions that make tutorship successful in promoting critical reflexivity in such a boundary crossing experience need to be further explored. Aim of this paper is therefore to analyze what tutorship conditions sustain the development of critical reflexivity in internship. For this purpose, we will present the case study of an internship program run by one of the largest universities in northern Italy.  相似文献   

Teachers’ intercultural competence: a requirement or an option in a culturally diverse classroom?     

Ibis Marlene Álvarez Valdivia  Iosbel González Montoto 《International Journal of Inclusive Education》2018,22(5):510-526

This paper reports an exploratory study of the development of intercultural competence (IC) in elementary school teachers in Catalonia, Spain, utilising mixed-method quantitative and qualitative assessments. Through enrolment in a teacher training activity, the starting point was the administration of the Intercultural development inventory (IDI) to assess IC. Later, a discussion group was held to reflect on the results of the evaluation and to discuss educational practices in the face of cultural diversity. The quantitative IDI findings indicated that, regardless of the presence of foreign origin students at schools, participant teachers overestimate their level of intercultural sensitivity; there is a tendency to emphasise similarities in all cultures, which can minimise significant cultural differences. Nevertheless, the teachers became interested in cultural diversity after considering their potentially controversial and problematic educational context. Beyond admitted limitations of this study, inherent to small-scale methodological approach, our practice-based reflective proposal highlights obstacles and potentialities for managing cultural diversity in the classroom. These findings support the conclusion that IC is distributed throughout members of a community rather than being strictly an individual attribute. At the same time, the study thus demonstrates a mixed-method training design as an effective means of developing and assessing IC.  相似文献   

The mirror’s curse: Weight perceptions mediate the link between physical activity and life satisfaction among 727,865 teens in 44 countries     

Silvia Meyer  Rebekka Weidmann  Alexander Grob 《运动与健康科学(英文)》2021,10(1):48-54

Purpose:The present study aimed to examine the link between physical activity(PA)and life satisfaction in a large international study of adolescents.We also aimed to test whether overweight and underweight perceptions act as mediators and whether age and sex acted as moderators.Methods:For this purpose,we analyzed data from the Health Behavior in School-aged Children study,which comprises 727,865 observations from 44 nations at 4 measurement occasions.Results:Multilevel analyses revealed a positive link between PA and life satisfaction.In addition,underweight and overweight perceptions mediated the effect of PA on life satisfaction.We further found that age and sex acted as moderators.In older adolescents,stronger effects were found in the links between PA and life satisfaction,PA and overweight perception,and both weight perceptions and life satisfaction.In addition,in female adolescents,the link between overweight perception and life satisfaction was stronger.Conversely,the links between PA and both weight perceptions were stronger for boys.Conclusion:The results suggest that weight perception explains part of the relationship between PA and life satisfaction in adolescents and that these effects vary as a function of age and sex.  相似文献   

New concepts in reassessing mining heritage: A study and its implications from the Ancient Iron Mine of Llumeres (North Spain)     

José Paulino Fernández Álvarez  A. García-Lengomín Pieiga  C.J. Suárez-Lázare 《Journal of Cultural Heritage》2010,11(2):172-179

The possibility of giving a continuing value to an abandoned historic mine is not only of academic interest but can be a crucial economic and heritage issue for regions with long mining traditions but which are now severely affected by mine closures. This article suggests a different perspective on the rationale for studying, preserving and developing our mining heritage as an educational facility. To illustrate the case, the ancient iron mine of Llumeres, in the Asturias region, in North Spain, is presented as an example. A key point of our thesis is that a closed mine is not a ‘dead entity’ but simply in transition to another useful state and that after the closure, another organism arises, with very different appearance and vital signs. We suggest that this new organism be recognised for its high patrimonial value and that this heritage value be preserved. Accepting this point of view would mean an increase in efforts to identify and appropriately manage these vital signs. We propose that the particular mining-related aspects (which are usually viewed as negative, such as subsidence or groundwater modification), be considered as part of the heritage of the mining activity, considered in the widest sense. To facilitate understanding, these are discussed in comparison to those for a prehistoric cave, for which there is a broader experience and solid knowledge and recognition of heritage value. We have also analyzed the importance of recognising the geometric and functional relationships between the underground workings and the superficial signatures, in defining an extended patrimonial entity, which has been recently presented to the cultural and political authorities. For the case of the iron mine of Llumeres, we explain the methodology required to analyze and classify the documents in order to investigate and reconstruct the 3D geometric structure of the mine and how this can be integrated into a Geographical Information System (GIS) to improve management and editing of the information. Additionally, the historic mining technological methods employed in the underground workings of Llumeres have been studied and all the information integrated into a 3D visualization package and made available as a free 3D video sample of the subsurface information. In summary, this work represents a major step forward in improving our knowledge of the ancient iron mine of Llumeres and, as a consequence, it has been possible, for the first time, to consider the underground mining heritage in the framework of the better known (but as yet unrecognised) overground heritage. This new patrimonial entity offers enhanced possibilities for acceptance and recognition in a societal context and to aid that acceptance, we propose a radical conceptual change of perspective, pointing out new elements requiring research.  相似文献   

The scientific approach to the restoration and monitoring of mural paintings at S. Girolamo Chapel – SS. Annunziata Church in Florence

The scientific approach to the restoration and monitoring of mural paintings, at S. Girolamo Chapel – SS. Annunziata Church in Florence, is reported as a fruitful example of the synergic collaboration between restorers and scientists in the planning and development of conservative interventions. Before restoration, the painting technique and the state of preservation of the pictorial cycle have been investigated firstly by close examination of the painted surfaces and then by optical and/or SEM-EDS microscopy and μFT-IR spectroscopy on appropriately selected samples. In particular, the original constituent materials and those belonging to subsequent restorations were characterized together with those originating from decay processes. In this mural painting cycle, a peculiar “fresco” technique has been used although an auxiliary binder for pigment distemper has been also employed. The use of this technique, sometimes in an improper way together with uncorrected restoration interventions, are the main responsible of the unsatisfactory state of conservation of many painted areas. Preliminary conservation trials and scientific studies were carried out to design the most convenient restoration intervention and to verify the correctness and non-invasive of the necessary operations. Special attention was devoted to cleaning procedures, continuously monitored by a physico-chemical methodology, mainly based on microinvasive, microscopic and spectroscopic investigations, to evaluate the efficiency, advantages and drawbacks of the proposed cleaning procedures and define the most appropriate ones. Finally, specific decay markers have been recognized, by a comparison of the results obtained from the detached samples with those deriving from artificially aged models, to be used for a correct future monitoring and maintenance of the wall paintings.  相似文献
