Discourse markers and turn-planning at the pragmatics-prosody interface: the case of "allora" in spoken Italian
No full textIn recent research on discourse markers (DMs), it has been shown that these elements collaborate with prosody to convey crucial information about the organization of the discourse, both at the level of a single turn and the level of the overall conversation. In this article, we analyze the DM allora ‘then’, occurring in turn-initial position and followed by a silent pause in spontaneous monolingual dialogues between Italian native speakers. Various prosodic measures are taken comparing allora with the following intonational phrase (IP), to investigate the discursive relationship between the DM and the rest of the turn. The results show that the DM is peripheric as opposed to the general turn's prosodic planning: it is produced at a higher articulation rate and with a narrower range of pitch values than the following IP, and a pitch reset is visible between the two. The data suggest that allora and the following IP constitute two distinct units in the turn's planning. We argue that as m..
Asymmetry in vowel perception in L1: evidence from articulatory synthesis of an [i]-[e] continuum
Full text linkaussi disponible sur:http://www.geocities.com/ch_karypidis/docs/conferences/Karypidis_et_alii_AISV2005_en.pdfFor the past 25 years, a debate on whether vowel discrimination is affected by stimulus presentation order has been raised and the role of peripheral vowels in our perception has been under careful examination.In earlier studies, the method used to synthesize a vowel continuum has been by fragmenting, in equidistant points, the F1/F2 Euclidean distance between two prototypes (best exemplars of two different vowel categories). Nonetheless, the resulting sounds were rather unrealistic, inasmuch as some of them were assigned formant-value combinations that cannot be produced by a human vocal tract. Furthermore, the assignment of fixed F3 and F4 values generated a false spectral peak (around 3100 Hz and thus close to that of [i]) which induced the listeners to identify more [i]'s than they should have. Evidence from a recent study on vowel prototypes suggests that [i] has a very narrow perception zone, despite its acoustic stability and peripherality and notwithstanding the absence of a mid-close [e] in the system.Bearing these methodological inconsistencies in mind, we opted to prepare our stimuli using articulatory synthesis. Therefore, we have synthesized a prototypic French [i] (stimulus no. 1, the most extreme) and then modified its parameters (jaw height and tongue position), gradually and in 9 steps, towards a prototypic French [e] (stimulus no. 10, the least extreme). We subsequently submitted the 10-vowel continuum to 34 native French listeners by conducting:a) an identification test in which listeners were requested to identify as [i] or [e] seven repetitions of each stimulus, presented in random order;b) a discrimination test in which listeners were presented with 34 stimulus combinations [18 one-step pairs (9 stimulus combinations, 2 orders) and 16 two-step pairs (8 stimulus combinations, 2 orders)] and were asked whether the two vowels were the same or different. The ISI (Inter-Stimulus Interval) was fixed at 250 ms and every pair was presented five times.Results from the identification test reveal a clear quantal perception of the two categories.The discrimination results demonstrate that: a) discrimination is more difficult when a more extreme (on the F2' dimension) stimulus is presented second and b) discrimination is significantly easier in the 2-step condition, in both orders of presentation

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
