Media Literacy in Italy
No full textIn Italy, the media literacy (ML) movement has a long grassroots tradition. Main actors are from civil society (academics, associations, church communities, teachers, media professionals, educators), with some growing support from local and national institutions. While digital literacy has stably entered the school system through funds, projects, and teaching resources aimed at improving students' digital skills, only recently has a more sociocultural view of digital technologies developed, thanks also to the National Plan for Digital School issued by the Ministry of Education in 2015. For the future, more commitment to developing the following three important directions is needed: conducting evaluative research on ML in order to have more evidence‐based knowledge of its impact on educational contexts, both formal and nonformal; enhancing training and producing quality resources for teachers and educators alike; fostering more coordination and networking among the various stakeholders involved in the field
Critical Theory Applied to Media Literacy
No full textTraditionally, one of the fundamental objectives of media literacy (ML) has been the development of the ability to exercise critical thinking about the media, unmask their “naturalness,” and bring to surface their ideologies and values. However, when we move from the abstract level of critical theory to the messy and complex practices enacted in educational contexts, this broad political goal, along with its claim about the “liberating” and “empowering” effect of the critical mind, is flawed with limitations and contradictions. Although the need remains—and is as urgent and vital as ever—to develop critical skills and attitudes, it is also necessary to graft critical theory onto the learning processes activated in practice. As a result of this, ML can be redefined as a form of praxis whereby theory and practice nurture each other in dialectical ways and contribute together to the construction of active citizenship

Mitochondrial Tricarboxylate and Dicarboxylate–Tricarboxylate Carriers: from animals to Plants.
No full textThe citrate carrier (CiC), characteristic of animals, and the dicarboxylate-tricarboxylate carrier (DTC), characteristic of plants and protozoa, belong to the mitochondrial carrier protein family whose members are responsible for the exchange of metabolites, cofactors and nucleotides between the cytoplasm and mitochondrial matrix. Most of the functional data on these transporters come from studies performed with the protein purified from rat, eel yeast and maize mitochondria or recombinant proteins from different sources incorporated into phospholipid vesicles (liposomes). The functional data indicate that CiC is responsible for the efflux of acetyl-CoA from the mitochondria to the cytosol in the form of citrate, the primer for fatty acid, cholesterol synthesis and histone acetylation. Like the CiC the citrate exported by DTC from the mitochondria to the cytosol in exchange for oxaloacetate can be cleaved by citrate lyase to acetyl-CoA and oxaloacetate and used for fatty acid elongation and isoprenoid synthesis. In addition to its role in fatty acid synthesis, CiC is involved in other processes such as gluconeogenesis, insulin secretion, inflammation, and cancer progression, whereas DTC is involved in production of glycerate, nitrogen assimilation, ripening of fruits, ATP synthesis and sustaining of respiratory flux in fruit cells.
This review provides an assessment of the current understanding of CiC and DTC structural and biochemical characteristics, underlying the structure–function relationship of these carriers. Furthermore a phylogenetic relationship between CiC and DTC is proposed
A new semi-automated measurement technique based on X-ray pictures for ankle morphometry.
No full textKnowledge of human joint morphology is important in orthopaedic surgery and in prosthesis design. The literature on quantitative morphological analysis of the ankle joint is particularly scarce. A semi-automated radiographic measurement method was developed to collect morphological measures of the ankle joint. The method was based on standard lateral and antero-posterior X-ray pictures of the ankle joint. These were then scanned and analysed by means of specialized software designed for the purpose, which requires minimal operator contribution. Accuracy of the method was experimentally assessed by in vitro direct measurements. Intra- and inter-operator variability was also tested. Accuracy was assessed to be within 1mm for most measurements. Repeatability was not affected by operator skill and was within 2mm. The newly proposed method was applied successfully on 15 male adult subjects and relevant results are reported. The method allows ankle morphology to be analysed in a large number of subjects providing reliable data for anthropometric statistics
Giovanni Filippo Ingrassia: A five-hundred year-long lesson.
No full textGiovanni Filippo Ingrassia was born five centuries ago in Regalbuto, a small town in the center of Sicily. After his medical course in Padua, under the guidance of Vesalius and Fallopius, he gained international fame as a physician and was recruited as a Professor of human anatomy in Naples and later in Palermo. He is remembered as "the new Galen" or "the Sicilian Hippocrates." He contributed to the knowledge of human anatomy through the description of single bones rather than the whole skeleton. In particular, he was the first to describe the "stapes," the "lesser wings of the sphenoid" and various other structures in the head (probably the pharyngotympanic tube) as well as in the reproductive system (corpora cavernosa and seminal vesicles). He was also a pioneer in the study of forensic medicine, hygiene, surgical pathology, and teratology. As Protomedicus of Sicily, he developed the scientific culture in this country. During those years, he faced the spread of malaria and plague with competence and authoritativeness. Indeed, he was one of the first physicians to suppose that certain diseases could be transmitted between individuals, therefore, introducing revolutionary measures of prevention. He is remembered for his intellectual authority and honesty. Five-hundred years after his birth, his teaching is still alive. In this article, we survey the life and contribution of this pioneer of early anatomical study
