A Place-Based Approach in EU Regional Development and Its Application in Latvia
2014
Abstract The EU’s regional development policy is gradually moving from the redaction of regional disparities towards regional development growth. The role and involvement of regional and local authorities in regional development policy is increasing. Global changes and challenges call for a growing need to develop more efficient regional development policy instruments that would result in growth and increased quality> of life. Place-based approach is a strategic approach aimed at the development of territorial resources. The aim of this research is to evaluate the role of place-based approach in regional development, to identify and assess the main elements and opportunities brought …
Improving geoconservation of the palaeontological heritage through a semiotic vision
2019
The panoply of reasons that may attract people to fossils, which result from the meaning they attribute to these palaeontological objects, may contribute to endangering of the integrity of the fossil record. Semiotics can be of great help to assist geoconservation actions, usually based only on expertise statements, and are of particular relevance in palaeontological heritage inventory, evaluation, conservation, valuation and monitoring procedures. This work argues that fossils can be envisaged as signs displaying different meanings among experts and non-specialists. Such meanings support the heritage contents and values attributable to any palaeontological object and are affected by the re…
In search of an integrated framework of business longevity
2015
Even if the domain of business longevity has been enriched by the multidisciplinary nature of approaches used to investigate the phenomenon, the lack of a unifying perspective has impeded systematic research and caused definitional ambiguity. The main aim of this special issue is to extend existing knowledge on business longevity by integrating theoretical and empirical studies that adopt different approaches and perspectives. This is essential in order to identify the key factors of long-term success and the effects of longevity on firm performance. The multifaceted nature of business longevity research is mirrored in the five articles included in this special issue, that offer different a…
Different approaches to research and innovation in physics education at college and university
2019
Abstract In this article we report a Symposium organized by GTG-Physics Education Research at University (PERU) with different proposals that includes innovative educational approaches and research on problems of teaching-learning physics at university. In the second section, two research projects are described on teaching specific curriculum topics that present special difficulties for students. In the next section the third project on a work experience in the laboratory that takes into account the characteristics of scientific work, is presented. Finally, the fourth project presents a way to investigate the types of student reasoning. In the discussion, the importance of research projects…
An inquiry-based learning path to introduce modern physics in high-school
2018
Although Modern Physics (MP) is a scientific field of increasingly interest, due to its mathematical and conceptual difficulty, it was not generally taught in Italian high-schools. Recently, in order to reduce the gap between school curricula and modern technology, the Ministry of Education promoted the inclusion of MP in Italian secondary schools. MP hot topics produce interest and enthusiasm in learners at all ages, but to address this topic in high school in an effective way it is necessary to translate complex theories and highly-advanced experiments into an understandable language appreciated by students. In this contribution, we discuss an inquiry-driven learning sequence suitable to …
Gendered Life-Course Patterns in Post-Socialist Romania: An Illustration from Households Situated in Precarious Prosperity
2017
AbstractThis paper documents the gendered aspects of changes affecting the life course of Romanians post-socialism, and the meanings men and women—with ages spanning across various age cohorts—employ to make sense of their experiences. Based on qualitative data collected during research on precarious prosperity among Romanian households conducted in 2013, the findings show that major shifts occurred in the timing of life events. Romanians’ life courses and their work trajectories have been unevenly affected depending on their intersectional belonging to gender, area of residence and life stage at the moment of the political transition. The analysis of work trajectories unravels increasing g…
Poder local y evolución social en el País Valenciano del siglo XIX
2019
This paper offers the achievements and lacks of the studies on local power in the ancient Kingdom of Valencia during the XIXth century. The breakdown of the Ancien Regime by the liberal revolution is the point of departure. The process of social change started whith the revolution continued ever after the failure of the democratic experience thet begun at 1868. To discuss these topics (not always shared by spanish historians), it would be proposed the analysis of local cases during long-termed periods and a social approach to politics, specially referred to attitudes and action of lower social groups.
Investigation of archaeological amphorae from the Egadi battles
2022
Abstract Archaeological ceramics are considered one of the most important sources of both technological and chronological information. Here, the investigation of some archaeological underwater amphorae from the Egadi’s Battle, that decided the end of the First Punic War (241 B.C.), is reported. X-ray Diffraction (XRD), X-ray Fluorescence (XRF), petrography, and Thermoluminescence (TL) were used to determine the composition of the amphorae and to evaluate the compatibly of their age with the above Battle. Considering the historical importance of the act and the well-defined historical collocation these amphorae represent an interesting archaeometric case study.
Portable Spectroscopic Techniques for the Non-invasive Identification of two historical yellow pigments: Applications and Practical Challenges
2022
Abstract Decades of technological advances in instrumental analysis have transformed many techniques from laboratory in portable analytical tools with increasing their applicability in situ to the study of cultural heritage. It is known that the painting realisation varies from artist to artist, and the identification of the pigments provides a decisive contribution to trace their authenticity and to support an appropriate restoration work. However, in some cases, due to the complexity of painting composition, it is difficult to distinguish between pigments having a similar chemical composition and colour. Here, a systematic study through combined use of portable non-invasive spectroscopic …
The holonic approach for flexible production: a theoretical framework
2011
This paper discusses the body of knowledge about Holonic Approach to theoretically demonstrate how Holonic Production System (HPS) can be a convincing choice to overcome the problems of traditional production systems? architectures. Today, enterprises are trying to find ways to manage the growing environmental complexity that is well described by Complex Systems Theory (CST). After the focus on the main problem regarding environmental complexity, the Holonic system and the Holonic Production System will be analyzed. The paper will focus the potential of HPS to adapt and react to changes in the business environment whilst being able to maintain systemic synergies and coordination through the…
