L’antropologia ha avuto un notevole impatto sulla cultura moderna specialmente nel rimarcare come le diversità culturali esistenti siano poco adeguate alla universalizzazione proposta dalla tecnologia. Lo spazio e la città, naturalmente, non fanno eccezione. La revisione dell’approccio ortodosso del Movimento Moderno operata dal Team X era basata su questo cambiamento culturale, epitomizzato dalle scoperte di Levi Strauss, un riferimento primario per quegli architetti. Naturalmente il contesto culturale era molto più ampio, in quanto comprendeva, fra l’altro, la sociologia, l’arte e l’esistenzialismo. Citiamo semplicemente le fondamentali teorie di Paul Ricoeur sui rischi della universalizz…
Engaging universities in social innovation research for understanding sustainability issues
2017
International audience; The paper presents the analysis of a three-stage research conducted by the authors within a social innovation project in collaboration with international master students of Riga Technical University for determining the factors, which motivate people to be involved in the solution of social problems. The authors not only analyse and use the outcomes of the students’ research but also provide feasibility study of using the potential of study research at the university, for implementing serious research projects. Data collection from Africa, Asia, America and Europe was organised jointly by all the students via web-based survey for creating an original data base for the…
The Influence of Hyaluronic Acid Biofunctionalization of a Bovine Bone Substitute on Osteoblast Activity In Vitro
2021
Bovine bone substitute materials (BSMs) are used for oral bone regeneration. The objective was to analyze the influence of BSM biofunctionalization via hyaluronic acid (HA) on human osteoblasts (HOBs). BSMs with ± HA were incubated with HOBs including HOBs alone as a negative control. On days 3, 7 and 10, cell viability, migration and proliferation were analyzed by fluorescence staining, scratch wound assay and MTT assay. On days 3, 7 and 10, an increased cell viability was demonstrated for BSM+ compared with BSM− and the control (each p ≤ 0.05). The cell migration was enhanced for BSM+ compared with BSM− and the control after day 3 and day 7 (each p ≤ 0.05). At day 10, an accelerated wound…
Archaean Crystalline Rocks of the Eastern Kaapvaal Craton
2019
The eastern part of the Kaapvaal Craton represents a classical granitoid-greenstone terrain and contains the oldest rocks of the African continent, exhibiting about 1000 Ma of crustal evolution from 3.66 to 2.67 Ga. The granitoid rocks predominantly consist of the tonalite–trondhjemite–granodiorite (TTG) association with true granites becoming abundant at about 3 Ga. Greenstones are represented by the well-preserved and well-studied 3.54–3.2 Ga Barberton Greenstone Belt and smaller ca. 3.45 Ga greenstone belt remnants infolded in TTG gneisses around the BGB as well as in the Ancient Gneiss Complex in Swaziland. The origin of both the TTGs and greenstone units is still debated as strong defo…
Early Propensity to Migrate: A Descriptive Analysis from A Survey of Schooled Teenagers in a Southern Italian City
2018
The brain drain from the south of Italy is a well-known and unfortunately increasingly alarming phenomenon. In recent times, the demographic decline due to migration has been coupled by a worrying decrease in the average age at which this process starts. While most of the existing literature has looked at the problem looking at migrant workers, especially in relation to their level of schooling or education, here we look at the propensity to migrate at an earlier stage of life while people are still in their secondary school studies. Using a unique field survey conducted over a large sample of students in the city of Palermo we uncover that more than three quarters of the interviewed sample…
The Role of the Creative Industries: Translating Identities on Stages and Visuals
2018
Drawing on research on narrative theory (Baker, 2006, 2014) in translation and interpretation studies, on the interdisciplinary relationship between translation studies and the visual and performing arts, and on the principal diversities between media discourse representations and aesthetic constructions on the topic of the migration crisis, this study addresses the issue of transferring cultural difference and language diversity within public and digital spaces through the telling and visualization of authentic stories belonging to migrant people, which contribute to the reversal of anti-refugee media discourses. Against the lens of a political reframing of migrant communities in the arts,…
Chronology for the Cueva Victoria fossil site (SE Spain): Evidence for Early Pleistocene Afro-Iberian dispersals
2014
Cueva Victoria has provided remains of more than 90 species of fossil vertebrates, including a hominin phalanx, and the only specimens of the African cercopithecid Theropithecus oswaldi in Europe. To constrain the age of the vertebrate remains we used paleomagnetism, vertebrate biostratigraphy and (230)Th/U dating. Normal polarity was identified in the non-fossiliferous lowest and highest stratigraphic units (red clay and capping flowstones) while reverse polarity was found in the intermediate stratigraphic unit (fossiliferous breccia). A lower polarity change occurred during the deposition of the decalcification clay, when the cave was closed and karstification was active. A second polarit…
Profilin1 regulates sternum development and endochondral bone formation.
2012
Bone development is a dynamic process that requires cell motility and morphological adaptation under the control of actin cytoskeleton. This actin cytoskeleton system is regulated by critical modulators including actin-binding proteins. Among them, profilin1 (Pfn1) is a key player to control actin fiber structure, and it is involved in a number of cellular activities such as migration. During the early phase of body development, skeletal stem cells and osteoblastic progenitor cells migrate to form initial rudiments for future skeletons. During this migration, these cells extend their process based on actin cytoskeletal rearrangement to locate themselves in an appropriate location within mic…
Tracing European Founder Lineages in the Near Eastern mtDNA Pool
2000
Founder analysis is a method for analysis of nonrecombining DNA sequence data, with the aim of identification and dating of migrations into new territory. The method picks out founder sequence types in potential source populations and dates lineage clusters deriving from them in the settlement zone of interest. Here, using mtDNA, we apply the approach to the colonization of Europe, to estimate the proportion of modern lineages whose ancestors arrived during each major phase of settlement. To estimate the Palaeolithic and Neolithic contributions to European mtDNA diversity more accurately than was previously achievable, we have now extended the Near Eastern, European, and northern-Caucasus d…
