Introduction: Urban plots, organizing cities
No full textThis chapter explores the processual nature of urban phenomena, considering the organizational aspects of urban space and the material features of organizations as having a common, heterogeneous ground. A matter of concern is the machinery around which entities are assembled and challenged. Cities are intrinsically indeterminate entities, and they are constantly constructed through controversies where action is distributed among actors and actants that assemble, re-present and translate each other. The issue of public noise in the historic city centre as reported in the local newspapers provided useful insights into this mechanism. The chapter comprises various contributions in which memory has become a major issue within discussion on urban reorganization. Grning's analysis is emblematic in this regard, because it deals with the urban transformation of East German cities, and particularly with the tangle of symbolic and material traces of the city of Leipzig
Addressing conspiracy theories through Media and Data Literacy Education. An exploratory case study
Get PDFLately conspiracy theories (CT) are increasingly hovering over Education Studies, mostly as problems in search of a solution. This paper problematizes this educational solutionist discourse by reflecting critically on different framing of CT (i.e. epistemological and ethico-political) and some related educational responses, ranging from pre/debunking strategies to democratic discussion. In addition, Media Data Literacy Education (MDLE) is presented as a viable educational approach to address CT circulating onlife. The approach is empirically explored through an online workshop with a small group of social workers attending a course for socio-pedagogical educators at the University of Florence. A qualitative mixed methodology is used to explore the pedagogical relevance of the MDLE intervention in addressing the educational challenges posed by CT and to highlight a possible critical rethinking of participants on the CT and their data. Results suggests that participants see MDLE as a valid pedagogical strategy to guide different learners (adolescents, general public and themselves) in the critical evaluation of media (dis)information. In addition, although the workshop seems to have enhanced participants’ critical thinking about mediatisation and datafication of CT further research is needed to develop and evaluate this pedagogical strategy, especially in relation to multiperspectival thinking and democratic discussions of CT in formal educational contexts
Alfabetizzazione critica ai dati e alle teorie del complotto : un approccio media educativo
No full textIl presente contributo chiarisce come l’alfabetizzazione critica ai dati non sia solo uno strumento per affrontare le sfide della datificazione, ma, combinata ad un approccio media educati- vo, possa diventare una strategia di contenimento dell’“infode- mia” di disinformazione che caratterizza il tempo presente. L’a- nalisi critica dei media, insieme alla produzione creativa, è una strategia didattica tipica della media education e può contri- buire ad aumentare la comprensione delle teorie del complotto che circolano in rete. Dopo aver mostrato come le teorie del complotto siano interpretabili come culture e pratiche mediali ed aver illustrato la specificità dell’approccio media educativo per affrontarle, si espone il ruolo che la data literacy può rive- stire per sviluppare la capacità di agire in modo significativo e proattivo nella società datificata. Infine, un esempio di analisi critica di un data storytelling, appartenente ad una narrazione complottista, conclude la riflessione. Nelle conclusioni si deli- nea come tale approccio media educativo applicato ai dati pos- sa contribuire a sviluppare competenze civiche per affrontare le distorsioni delle comunicazioni complottiste
INITIAL TEACHERS EDUCATION : THE ETWINNING EXPERIENCE IN FIVE ITALIAN UNIVERSITIES
No full textEducation systems all over the world are constantly pushed to adapt to society's changing needs. Initial teacher education is also a complex activity to design and manage, with an increasing number of stakeholders and numerous levels of government. Teachers' knowledge development is not an isolated phase that happens during university study, but it is rather part of a longer and more dynamic process along a lifelong learning continuum (Musset, 2010). Professional development programmes can impact positively on teaching and learning processes: teachers with greater preparation are more confident and successful with pupils than those who are not given sufficient tools and knowledge and this can make a substantial difference in what children learn (Darling-Hammond, 2000).
Since its launch in 2013 as part of the university training pathway for pre-service Italian teachers, the "eTwinning for Future Teachers - Initial Teachers Education (ITE)" initiative has grown significantly all over Europe. In this regard, Italy represents a good example of the initiative’s relevance as it occupies the first place in Europe both in terms of quantity and relevance of the experience, with more than 20 universities participating and over 12.000 university students involved (INDIRE, 2021). eTwinning in particular concerns increasingly important topics for teacher training recommended in European countries' educational and social policies (ET2020 Working Group on Schools Policy, 2015): from multilingualism to innovative didactics, the ethical use of digital devices for teaching and self-training and school collaboration. Previously, surveys on the teaching and digital competencies of eTwinners were undertaken (Fabbro, Ranieri & Imbimbo, 2021), as well as distance learning imposed by the Covid 19 pandemic (Fila et al., 2021).
The present study is part of a broader research project on the dissemination and implementation of ITE in Higher Education in Italy. The study aims to identify practices and organisational models in use in five universities, as well as potentials and lines of development accompanying the integration of eTwinning in initial teacher education. The specific objective guiding the research is to find out in different contexts what the benefits and criticalities of the eTwinning initiative are in terms of organising and managing Higher Education for future teachers. In this research study, data collected through 21 in-depth semi-structured interviews with various stakeholders and analytic procedures of the multiple evaluation case study (Yin, 2003) are the main source of evidence. From stakeholders’ perspective, the most significant advantage of joining ITE is the expansion of the collaboration network in the national and worldwide academic communities, as well as in the educational system. Collaboration between students, schools and universities takes various forms, adjusting to the needs and requirements of institutions and leveraging training or partnership possibilities to allow students to receive international exchange experiences as part of their degree programme
Energy and environmental flows: Do most financialised countries within the Mediterranean area export unsustainability?
No full textThe literature dedicated to the problems of transboundary pollution often aims to verify what the environmental and energy interactions between countries are. Little attention is paid to the financial relations of the phenomenon. We analyze how financial, environmental and energy flows have been redistributed within the main Mediterranean countries, with particular reference to pollution. Applying advanced methods of correlation, we verify the dynamics of transfer processes with the aim of assessing whether the link between economic and financial and environmental flows might support the hypothesis that rich countries export environmental emissions to poor ones. Our results show that richer countries have a significant propensity to export energy, financial flows and polluting emissions. The imbalance is even greater for emissions with local impact. This process is accompanied by a substantial increase in the financial activities of the North Mediterranean countries to the detriment of those of the South, which progressively increase their indebtedness. We find out that the economic and financial development of the North Med is accompanied by an increasing environmental impact measured by the various types of emissions covered by our study. The research shows how the most industrialized countries of the Mediterranean area are increasing the economic and financial gap with respect to the Southern Mediterranean countries

Comparisons with other species. Craugastor gabbi differs from all the other craugastorids of Lower Central America, except for those in the C. podiciferus species group, which have basal webbing between the toes and a narrow head, i.e., head width 31–38 % SVL. Craugastor gabbi differs from other members of the C. podiciferus species group by having the following characteristics (condition for C. gabbi in parentheses, see Table 4). Craugastor gabbi differs from C. bransfordii, C. polyptychus and C. underwoodi by having a thenar tubercle equal to or slightly smaller than the palmar tubercle (thenar tubercle definitely much smaller than palmar tubercle, Fig. 5); C. gabbi differs from C. podiciferus by having a prominent calcar tubercle on the heel (calcar tubercle absent) and by the absence of supernumerary tubercles (supernumerary tubercles well defined in fingers and toes); from C. jota (Lynch 1980) by having a prominent calcar tubercle on the heel (calcar tubercle absent); from C. lauraster by having an immaculate white venter (having a cream-colored venter with dark pigment reaching the midline, Fig. 4) and by having a much shorter Finger I than Finger II (Finger I slightly shorter than Finger II); from C. persimilis by having toes unwebbed (basal webbing between toes), by having dorsum and forelimbs areolate (dorsum and forelimbs shagreen), and by having a much shorter Finger I than Finger II (Finger I slightly shorter than Finger II); from C. stejnegerianus by having an immaculate white venter, [only the 8 % of the specimens reviewed here had a venter with dark pigment reaching the midline] (venter cream-colored with dark pigment reaching the midline, Fig. 6) and by having a significantly larger TL/SVL and IOD/HW and a significantly smaller HL/SVL and E-N/SVL. Is important to note that the specimens of the northernmost populations of the Central Pacific of Costa Rica had the venter with dark pigment reaching the midline; however, these populations are under taxonomic revision because they could represent a separate species.

The scant variation among the paratypes is described as follows. Tympanic membrane differentiated in UCR 21863, UCR 21865, and UCR 21876; a pair of dorsolateral folds extending from the axillar level to the sacrum in UCR 21865 and UCR 21867; a pair of lateral folds extending from the orbit to the sacrum in UCR 21865; discoidal fold indistinguishable in UCR 21863, UCR 21865, UCR 21867 and UCR 21876; two tubercles postrictal in UCR 21867, semifused in UCR 21863 and UCR 21865; inner tarsal fold incomplete in UCR 21863. Fingers without medial supernumerary tubercles in UCR 21863 and UCR 21865; only two palmar accessory tubercles in UCR 21863, UCR 21865, and UCR 21876; toes without medial supernumerary tubercles in UCR 21863 and UCR 21865; dorsum with a pair of broad lateral light stripes extending from the snout to the groin, these stripes are divided by a pair of dark stripes extending from the axillar level to the groin, forming a stripe pattern in UCR 21876, with a pair of lateral light stripes extending from the orbit to the groin in UCR 21865; labial marks absent in UCR 21863; supratympanic mark absent in UCR 2 1876. Variation in other specimens not observed in paratypes. Some specimens with the snout subelliptical in dorsal view; canthus-rostralis rounded in some; others with vomerine teeth obtuse; some specimens with a pair of dorsolateral folds extending from the orbit to the anus; lateral folds variable to absent, from the orbit to groin, from the orbit to anus, from the axillary level to sacrum and from the axillary level to groin; supratympanic fold distinctly curved downwards present in several specimens; some with only one postrictal tubercle; a specimen with inner tarsal fold complete; the inguinal gland was elevated and prominent in some individuals, in others this was not evident, although we did not observe a relation between this characteristic and sex. Some specimens with four or five ulnar tubercles in a row; some without grooves in fingers; at least one specimen with disk expanded in Fingers III and IV; webbing between Toes I-II can reach proximal subarticular tubercle, the web between Toes II- III-IV can reach least half of the proximal phalanx. Patterns variation. In comparison with the other species of the C. podiciferus species group, C. gabbi had low levels of dorsal color pattern variation. The holotype had the formula MZ 1 OQ (mottled dorsal pattern with stripe supratympanic, skin texture irregularly granular and a pair of dorsal ridges); this formula was present in 25 % of the specimens. The most common formula was UZ 1 OQ at 34.4 %, described by Savage & Emerson (1970) as Morpho V. The following formulae were also observed: LZ 1 OQ present in 9.4 %; UZ 1 NQ, MOQ, and MO present in 6.3 %; UZ 2 OQ, LZ 1 NQ, LOQ, and MZ 1 NQ present in 3.1 %. The dorsal background color ranged from light gray to blackish brown; at least one individual presented longitudinal lines from the orbit to groin, light color on a dark background, and another two specimens presented dark lines on a light background. In eight individuals, the pattern of contrasting mottles was strongly prominent. The throat color varied from cream to dark brown, strongly contrasting with the lighter-colored venter. No association between the throat color and sex was observed. At least one individual had a well-defined mask, and the head of another was completely black. The supratympanic dark mark was present in most, but not all, individuals; labial bars were also present in most, but not all, specimens. Natural history notes. Craugastor gabbi is abundant in the Fila Costeña, Coto Brus region. Santos-Barrera et al. (2008) reported this species at 21 of the 27 study sites, stating that C. gabbi was the most abundant amphibian in the forest and the coffee plantations and was also present in pastures. Usually, this species is associated with leaf litter. This species may reach densities of up 4586 individuals/ha (Scott 1976). Craugastor gabbi is diurnal (Savage 2002) and reproductively active throughout the year (Santos-Barrera et al. 2008). The type series was found together in a patch of primary forest, active at approximately 12:00 h on the leaf litter and away from any body of water. No reproductive activity was observed, and no calls were recorded. The call is unknown, but it is likely an inconspicuous single slow squeak, as reported for C. stejnegerianus (Savage 2002). We did not find gravid females, and pairs in amplexus were not observed. Geographic distribution. Craugastor gabbi is restricted to the premontane forest near the type locality of Fila Costeña, Costa Rica and the premontane forest of Cordillera de Talamanca in the extreme southwestern region of Costa Rica and western Panama near the present international border (Fig. 1). The altitudinal range of the new species is 1100–1280 m elevation. Craugastor gabbi overlaps with the range of C. underwoodi and C. podiciferus at the Las Cruces Biological Station, Fila Costeña, Coto Brus. Etymology. This species is named in honor of paleontologist William M. Gabb in recognition of his important contribution to the herpetology of Costa Rica as an explorer and collector, mainly in the Talamanca region.Published as part of Arias, Erick, Chaves, Gerardo, Crawford, Andrew J. & Parra-Olea, Gabriela, 2016, A new species of the Craugastor podiciferus species group (Anura: Craugastoridae) from the premontane forest of southwestern Costa Rica, pp. 347-363 in Zootaxa 4132 (3) on pages 354-358, DOI: 10.11646/zootaxa.4132.3.3, http://zenodo.org/record/25492
Muri come trame e infrastrutture urbane. Organizzare la città attraverso sensi, pratiche, narrative, controversie
No full textCome operano i muri nel dare forma allo spazio e alle pratiche urbane? Di che cosa sono fatti? Il capitolo propone una riflessione sui muri
