Resolving hiatus in (isi)Ndebele: An optimality theoretic account
No full textAbstractVowel hiatus is a dispreferred phenomenon in many languages. When vowel sequences arise through morphophonological concatenations in (isi)Ndebele, hiatus may be resolved in one of three processes: (i) one of the two vowels undergoes elision; (ii) one of the vowels (mostly the first vowel in the sequence) undergoes glide formation; and (iii) the two vowels undergo vowel coalescence – the merging of the two vowels into a neutral vowel that has the qualities of both the two initial vowels straddling a word boundary. This article examines these vowel hiatus resolution strategies in (isi)Ndebele, through the theoretical explications of Optimality Theory (OT) and CV Phonology. In (isi)Ndebele, the featural qualities of the two vowels straddling a word boundary and the morphological contexts at which the hiatal configurations occur determine what process repairs vowel hiatus. Hiatus resolution is also invariably ONSET and feature driven: driven by Preferred Syllable Structure Rules(PSSRs) and constraints
Social Media as Alternative Public Sphere for Citizen Participation and Protest in National Politics in Zimbabwe
No full textThe chapter examines and discusses the role and communicative potential of social media based platforms in citizen political participation and protests in Zimbabwe specifically focusing on the #thisflag movement on Facebook, Twitter and Whatsapp. #thisflag is a social media-based platform that rose to challenge the Zimbabwean government over the political and economic decay as well as rampant corruption characterising the country contemporarily. While a new phenomenon to Zimbabwe and Zimbabwean politics, the impact and communicative potential of social media as an alternative public sphere was recently tested in nationwide protest stayaway organised through the Facebook and Twitter movement under the #thisflag handle/brand. This chapter discusses the manners in which such social media platforms impact national politics in Zimbabwe as well as globally, specifically looking at the #thisflag movement as a case study. </jats:p
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
