The Moocs (R)evolution. A policy framework analysis at a European level
Full text linkAcademic institutions all over the world, as well as active stakeholders in the field of education and supporting services, are exploring Moocs to try and understand how learning and teaching environments are changing, what are the outcomes of such a novelty for different countries
and publics, to what extent the Moocs revolution can represent both a unique opportunity to open up education and a new business model. Born to help universities and academic institutions to innovate pedagogical models, Moocs are developing along different routes. Using a policy framework analysis approach, this paper presents the results of a European survey that questioned both public and private stakeholders on Mooc policy design, objectives and expected outcomes
On demand e serialità. L’informazione politica si fa push
No full textL’ultima edizione del Digital News Report (2023)1, pubblicato dal Reuters Institute for the Study of Journalism dell’Università di Oxford, documenta come l’informazione digitale stia cambiando formati e canali di fruizione. Se solo poco più di un quinto delle persone accede oggi alle notizie da siti e app dei giornali, diventano sempre più popolari le newsletter e i podcast. Cambiano le traiettorie della sostenibilità con un aumento dell’accesso
a pagamento: negli Stati Uniti il 56% degli intervistati sottoscrive un abbonamento,
l’8% di questi paga per ricevere una newsletter, il 5% per un podcast. In UK solo il 9% accede a prodotti news a pagamento, ma il 30% ha ascoltato almeno un podcast nell’ultimo mese. In Italia i sottoscrittori raggiungono il 12% e gli utenti podcasts oltre il 30%. Naturalmente, ogni paese fa storia a sé, ma l’indagine fornisce indizi di una inversione di tendenza del fenomeno noto come news-finds-me-perception, vale a dire la percezione diffusa che, attraverso i social, le notizie raggiungano gli utenti anche in presenza di comportamenti passivi di consumo (Gil de Zúñiga e Cheng, 2021). Va consolidandosi, dunque, la ricerca di informazione di qualità e la volontà di sostenere testate o esperti cui si attribuisce credibilità e fiducia (Fig. 1). Newsletter e podcast sono formati non nuovi, che si stanno ora giovando di quella cultura della serialità diffusa da piattaforme come Netflix. Tecnologie cosiddette
push, che garantiscono un alto livello di selezione e qualità editoriale, una fruizione on demand e uno stile narrativo fresco. In questa rubrica ne proponiamo alcuni esempi con una decisa preferenza per i canali di informazione politica e con un occhio a quelle iniziative che stanno diventando veri e propri asset strategici per la brand loyalty e la diversificazione delle audience, anche delle grandi testate
Raziskave besednega reda v stari grščini
Full text linkČlanek vsebuje pregled poglavitnih vprašanj, s katerimi se srečamo, kadar preučujemo besedni red v korpusnem jeziku. Pogoji za tovrstno raziskavo so v grščini razmeroma dobri, saj je na voljo dovolj raznovrstnih besedil. Težave nastopijo, ker gradivo ne ustreza docela pojmovnemu orodju, kot ga uporabljamo pri raziskavah besednega reda [v] živem jeziku - kjer se lahko vselej zanesemo na naravne govorce -, zato so večino raziskav v 20. stoletju zaznamovali izraziti metodološki premiki
Dokazi višjega reda v znanosti
Full text linkDespite our best efforts, we often fail to act in a perfectly rational manner. Recently, some epistemologists have suggested that we should admit our failings and develop a modest epistemology that would take our fallibility seriously. This includes accounting for the role of evidence of our irrationality, usually called higher-order evidence. It seems intuitive that modest reasoners should take such evidence into account. However, it turns out that incorporating higher-order evidence into a principled theory of what rationality requires is not an easy task. In this paper, I first review the debate about higher-order evidence, describing in detail the puzzle of higher-order evidence and the main positions about it in the literature. Then, I provide two novel examples of higher-order evidence, taken from science. I argue that these examples put pressure on the views that reject the role of higher-order evidence. These views commit themselves to the conclusion that some common scientific practices, such as evaluating evidence in systematic reviews or even running null hypothesis significance tests, are irrational.Kljub prizadevanju po nasprotnem pogosto ravnamo iracionalno. V zadnjem času so nekateri epistemologi predlagali, da priznamo svoje napake in poskušali razviti skromno epistemologijo, ki bo v zakup vzela dejstva o naši iracionalnosti. Pomemben del takšne epistemologije predstavlja tudi opis vloge dokazil o naši iracionalnosti, t. i. dokazil višjega reda. Intuitivno se zdi, da bi morali pri tvorjenju prepričanj takšna dokazila upoštevati. Vendar pa se izkaže, da vključevanje dokazil višjega reda v teorijo racionalnosti ni lahka naloga. Vtem prispevku najprej pregledam razpravo o dokazilih višjega reda, podrobno opišem problem dokazil višjega reda in predstavim glavne odgovore nanj. Nato predstavim dva nova primera dokazil višjega reda, vzeta iz znanosti. Trdim, da ta primera pod vprašaj postavljata stališča, ki zavračajo vlogo dokazov višjega reda. Ta stališča implicirajo, da so nekatere vsakdanje znanstvene prakse, kot sta vrednotenje dokazil v sistematičnih preglednih člankih ali celo izvajanje testov statistične značilnosti, iracionalne
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

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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
