Podcasting a tool for sustainable online learning environments. Experimental analysis of the new opportunities
No full textThe keyword which describes in the most
effective way Twenty-first century Higher
education is suggested by Daniel et al. (2009)[1] and
it is “expansion”. More and more people will invest
in their own education and in this process Higher
Education is on the front line. The need for
education and training, though, cannot be generic,
what nowadays society wants cannot be identified
in static knowledge. At the end of the learning path
students should be able to employ the outcomes of
learning in order to generate new learning. That is
why new solutions and methods must be acquired
and adopted. Being those the conditions, and having
at disposal the undeniable chances that the Internet
offers, a possible direction to be undertaken could
be the one that drives us directly to the
potentialities of distance education performed in
adaptive environments. The present contribution
aims at analyzing Higher Education present needs,
offers a general highlight of adaptive and intelligent
web based education systems and concentrates on
examples which better respond to the needs
previously highlighted
Lifelong Learning and the Development of a Critical Technology in Higher Education
No full text"An important passage in the 2010 OECD report (Organisation for Economic Co-operation and Development) underlines the need for formal education to enter the workplace: “in the nations where work is organized to support high levels of employee discretion in solving complex problems, the evidence shows that firms tend to be more active in terms of innovations developed through their own in house creative efforts” (OECD, 2010, theme 1, p. 10). . The key point is in fact that new skills are needed, because traditional skills learnt at school or at university are disappearing and are not deemed useful in facing the needs for innovation and growth that society today demands. The concept behind our project is therefore that of verifying the effectiveness of a model constructed to increase critical thinking skills, which is essential in environments such as those described by the OECD in the above-mentioned document, in order to apply this to settings where employed people are involved in training.. The present contribution aims to describe the results of a study carried out at DIPED - Dipartimento di Progettazione Educativa e Didattica (Department for Educational Design) at Roma Tre University, where the levels of critical thinking skills of students were assessed through an ad hoc content analysis protocol..
Contributi per la definizione di una tecnologia critica interdisciplinare.
No full text"The Project “Contributions to the definition of an interdisciplinary critical technology” stems from the results of a departmental research started by DIPED (Department for Educational Design) in 2011, “Contributions to the definition of a critical technology”, with the aim of favouring and promoting the development of critical thinking skills in higher education students, from different areas of study, offering online cultural insights. . The results obtained in the previous research, though highlighting a certain difficulty in argumentation and writing production, were comforting as regards the employment of the model (Poce et al., 2012) devised by the research group for the project.. The hypothesis to be verified aimed at establishing if proposing cultural insights to students, built according to specific structures on which guided discussions are carried out online, critical thinking skills are improved, notwithstanding the field of study. . Assuming that present higher education students show a widespread difficulty in writing and argumentation, the research group decided to extend the model devised in 2011 also to other areas of study to assess its efficiency. This has ben possible thanks to the creation of an ad hoc teaching and learning module entitled “Critical thinking skills and the reading of the classics”, available on the Orbis Dictus (Vertecchi et al. 2010) e-platform (www.orbisdictus.it), where two groups of students could access: one from the faculty of Education, University Roma Tre and one from the faculty of Engineering – University of Salento. . The activity allowed some general considerations. Notwithstanding the small numbers of the students involved (48 students in total in the year 2012), the opportunity to carry out the analysis with two different cohorts of students (2011 and 2012) from the Faculty of Education – Università Roma Tre allowed a diachronic evaluation of results. For the first time, then, the research group could employ the model also with another field of study students.. Taking into consideration the differences between the groups involved, data collected show a positive impact of a model that wants to make a critical use of technology and, employing consolidated teaching and learning structures, put democratically at disposal of everyone cultural insights, which are essential to educate “a free citizen in a free republic” (Garin, 1957, p.157)..
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Dedifferentiated liposarcoma of the pyriform sinus
Full text linkThe authors presented a second reported case of dedifferentiated liposarcoma of
the pyriform sinus in a 50-year old male, with a history of heavy smoking, airway obstruction and dysphagia. A computed tomography (CT) of the neck and thorax revealed a retroesophageal lobulated heterogenous mass. A laryngoscopic examination disclosed sessile polypoid mass in the right pyriform sinus. Microscopically, the neoplasm consisted of areas of well-differentiated liposarcoma and a non-lipogenic component (dedifferentiated component). These two parts were co-mingled, giving a mosaic pattern. Well-differentiated liposarcoma was characterized by adipocytes with a great variation in size, and multivacuolated lipoblasts. Immunohistochemical studies showed positive reactivity with vimentin and smooth muscle actin in non-lipogenic component. This neoplasm shows histological and immunohistochemical features of dedifferentiated liposarcoma with myogenic differentiation
Il carcinoma mammario insorto su tessuto ghiandolare soprannumerario: a proposito di un caso
No full textUnusual presentation of primary squamous cell carcinoma involving the interdental papilla in a young woman.
No full textA 33-year-old woman presented with what looked like an epulis at the interdental papilla between 22 and 23. We excised the lesion and histopathological examination surprisingly showed the presence of a well-differentiated squamous cell carcinoma that was not invading the underlying bone. We then did a radical excision including extraction of teeth followed by bony reconstruction. No recurrence or metastases have been seen during a follow-up of 12 months. © 2005 The British Association of Oral and Maxillofacial Surgeons
Oncocytic mucoepidermoid carcinoma of a submandibular gland: a case report and review of the literature.
Full text linkThis report describes the first recognized case of oncocytic mucoepidermoid carcinoma of a submandibular gland, and emphasizes the role of immunohistochemical study in the correct diagnosis of this tumour. This is only the second case in which this tumour has appeared as a completely cystic lesion. A review of the literature was carried out to clarify the clinical and pathological features of this rare malignancy
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
