THE PRODUCTION AND PERCEPTION OF EMPHASIS IN QASSIMI ARABIC
Full text linkThis work is embargoed by the author and will not be publicly available until December 2025.This dissertation explores emphasis effects (EE) in Qassimi Arabic (QA), examining whether EE functions as a phonetic or phonological process. EE is a well-documented phenomenon in Arabic linguistics, involving the influence of emphatic consonants on neighboring segments (Ghazali, 1977; Card, 1983; Davis, 1995; among others). The study also investigates emphasis perception in QA, specifically whether EE cues assist native QA listeners in identifying preceding or following consonants as emphatic or plain.As prior research exploring EE in various Arabic varieties has revealed variation among them, and limited research exists on emphasis perception by native Arabic listeners, this dissertation addresses these gaps by examining EE production and emphasis perception in the understudied variety of QA. In the production experiment, dynamic aspects of leftward and rightward EE on QA vowels were examined by analyzing second formants (F2) at 11 temporal points. Results indicate that leftward EE had a categorical effect on non-high vowels [a] and [aː], as well as the high front vowel [i], impacting them throughout their duration, providing evidence for it being a phonological process in QA. In contrast, rightward EE primarily affected the vowel onset, suggesting it as a gradual phonetic process rather than a categorical phonological one. In the perception experiments, the perceptual correlates of emphasis in QA were investigated using the gating paradigm (Grosjean, 1980). Native QA listeners accurately identified the following consonant using leftward EE cues, even within the shortest gate containing one-third of the vowel, indicating proficiency in using leftward EE cues throughout the vowel. However, for rightward EE cues, accuracy in identifying the preceding consonant as emphatic or plain improved significantly only when the entire vowel duration was audible. These findings align with the production experiment, confirming leftward EE as a phonological process and rightward EE as a phonetic process. The dissertation’s results have implications for understanding EE and emphasis perception in QA, emphasizing the importance of considering both phonological and phonetic processes when investigating EE and highlighting the significance of coarticulatory information in rightward emphasis perception. This nuanced understanding advances research into emphasis across Arabic varieties and Semitic languages.2025-12-1
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
Descriptive Analysis of Qassimi Arabic: Phonemic Vowels, Syllable Structure and Epenthetic Vowels, and Affrication
No full textThe present study seeks to provide a descriptive analysis of three phonological topics in Qassimi Arabic (QA)—a local variety of Najdi Arabic spoken mainly in Qassim, Saudi Arabia—based on data collected from a total of twenty-two native QA speakers. The topics are phonemic vowels, syllable structure and epenthetic vowels, and affrication. The participant recruitment was the same for all the three topics, but each topic was investigated using its own materials and methods. Regarding the phonemic vowels in QA, the study based the results on 157 words collected from three native Qassimi speakers. Previous studies have claimed that QA has eight phonemic vowels—three short and five long. However, the findings argue that QA has nine phonemic vowels—four short vowels and five long ones. The four-short vowel system is an empirical claim since previous studies indicated that /a/ is a conditioned allophone, which is challenged in the present study by providing clear minimal pairs, such as /daf/ ‘warm up’ and /daf/ ‘he pushed’. It also indicates that short vowels have narrow vowel space compared to their long counterparts. As for the syllable structure and epenthetic vowels, the study based its results on the analysis of 419 words targeting the syllable structure, and 72 words targeting epenthetic vowels. The results reveal that QA has 12 syllable structures, which are CV, CVV, CCV, CCVV, CVC, CVVC, CCVC, CCVVC, CVCC, VC, and VCC. The latter two structures are empirical findings to the study since the previous body of research claim that QA has the first ten structures. Regarding the location epenthetic vowels, the results suggest that they can occur, in a sequence of multiple consonants, after the first consonant, after the second consonant, and after the third consonant. These different locations are conditioned by the surrounding environment and/or the syllable structure. In addition, the quality of epenthetic vowels seems to be inconsistent, in coda group, since the participants inserted either [i], [a], [ϵ], or [i], while it is consistent in across-stem group. In discussing the affrication, the present study investigates the environment that triggers the affrication process in the Qassimi Arabic (QA), and explores whether the syllabic structure or position in the word play a role in the process. It also investigates the phonological domain of the affrication, and the activeness of the affrication process. Based on the 282 words that have the sounds /ts, dz, k, g/, the study has identified important counter evidence to the claim that the affrication process is triggered by front vowels. This study shows that the alveolar affricates /ts/ and /dz/ occur in the environment of almost all vowels since it is occurred before/after [i, e, a, “special character omitted”, o] as well as providing multiple contrastive environments including several minimal pairs, (e.g. [jImk In] ‘maybe’ [jImtsIn] ‘overtake’). It also provides counter evidence for the claim that geminate consonants block the affrication. This study also demonstrates that the syllabic structure is irrelevant to the affrication process since it occurs in onset and coda position in monosyllabic and multisyllabic words. Finally, the study reveals that the affrication process cannot be triggered by affixation, even if the claimed environment is met, which might indicate that to domain of the affrication is the stem in which all the affricated words are monomorphemic words. In sum, the present study suggests that Najdi varieties should be studied individually since they tend to have specific features that might not be shared with other varieties. That is, just because a feature may be found to exist in one type of Najdi Arabic, it cannot be assumed that feature is also attested in all other closely related varieties
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
