Design, development and first evaluation of a client/server system for managing and querying linguistic corpora

This thesis is concerned with the role played by software tools in the analysis and dissemination of linguistic corpora and their contribution to a more widespread adoption of corpora in different fields. Chapter 1 contains an overview of some of the most relevant corpus analysis tools available today, presenting their most interesting features and some of their drawbacks. Chapter 2 begins with an explanation of the reasons why none of the available tools appear to satisfy the requirements of the user community and then continues with technical overview of the current status of the new system developed as part of this work. This presentation is followed by highlights of features that make the system appealing to users and corpus builders (i.e. scholars willing to make their corpora available to the public). The chapter concludes with an indication of future directions for the projects and information on the current availability of the software. Chapter 3 describes the design of an experiment devised to evaluate the usability of the new system in comparison to another corpus tool. Usage of the tool was tested in the context of a documentation task performed on a real assignment during a translation class in a master's degree course. In chapter 4 the findings of the experiment are presented on two levels of analysis: firstly a discussion on how participants interacted with and evaluated the two corpus tools in terms of interface and interaction design, usability and perceived ease of use. Then an analysis follows of how users interacted with corpora to complete the task and what kind of queries they submitted. Finally, some general conclusions are drawn and areas for future work are outlined.

Comparing genetic and linguistic diversity in African populations with a focus on the Khoisan of southern Africa

The interaction between disciplines in the study of human population history is of primary importance, profiting from the biological and cultural characteristics of humankind. In fact, data from genetics, linguistics, archaeology and cultural anthropology can be combined to allow for a broader research perspective. This multidisciplinary approach is here applied to the study of the prehistory of sub-Saharan African populations: in this continent, where Homo sapiens originally started his evolution and diversification, the understanding of the patterns of human variation has a crucial relevance. For this dissertation, molecular data is interpreted and complemented with a major contribution from linguistics: linguistic data are compared to the genetic data and the research questions are contextualized within a linguistic perspective. In the four articles proposed, we analyze Y chromosome SNPs and STRs profiles and full mtDNA genomes on a representative number of samples to investigate key questions of African human variability. Some of these questions address i) the amount of genetic variation on a continental scale and the effects of the widespread migration of Bantu speakers, ii) the extent of ancient population structure, which has been lost in present day populations, iii) the colonization of the southern edge of the continent together with the degree of population contact/replacement, and iv) the prehistory of the diverse Khoisan ethnolinguistic groups, who were traditionally understudied despite representing one of the most ancient divergences of modern human phylogeny. Our results uncover a deep level of genetic structure within the continent and a multilayered pattern of contact between populations. These case studies represent a valuable contribution to the debate on our prehistory and open up further research threads.

The role of language in tv shows and its impact on the audience: A linguistic analysis of Game of Thrones

Through the analysis of American TV show Game of Thrones, this dissertation will focus on the linguistic issues concerning the adaptation from books to television, the power of language over the audience, and the creation of two languages, with all the linguistic and cultural implications related to this phenomenon.

Linguistic gender identity construction in political discourse : a corpus-assisted analysis of the primary speeches of Barack Obama and Hillary Clinton

The present study is concerned with exploring the linguistic identity construction of Barack Obama and Hillary Clinton in the context of USA 2008 Democratic Party primaries. Thus, their speeches are examined in order to detect the aspects of identity that each politician resorted to in the process of projecting a political identity. The study, however, takes a special interest in the ways in which gender identity is projected by Obama and Clinton. Moreover, the notions of gender bias as well as gender representations are also investigated.

Acknowledging linguistic diversity in a multicultural society: the issue of indigenous languages in Colombia.

Nowadays, modern society is gradually becoming multicultural. However, only in the last few years awareness on its importance has been raised. In the case of Colombia, multiculturalism has existed since the pre-Columbian period and today there are more than 80 ethnic groups and 65 indigenous languages in the country. The aim of this work is to illustrate the status of indigenous languages in Colombia and to enlighten about the importance of recognizing, protecting and strengthening the use of these native languages. Subsequent to this, it will be point out that linguistic diversity should be considered a resource and not a barrier to achieve unity in diversity. Finally, ethno-education will be presented as an adequate educational program that may guarantee an equal linguistic representation in the country.

"Linguistic Imperialism" di Robert Phillipson: proposta di traduzione di alcuni estratti

L'oggetto di questo elaborato è la proposta di traduzione di alcuni passaggi tratti dal terzo capitolo dal manuale Linguistic Imperialism di Robert Phillipson. L'autore ha scritto un saggio di linguistica applicata che discute dell'esistenza dell'imperialismo linguistico e delle conseguenze che ha sulla realtà linguistica moderna. Il terzo capitolo, in particolar modo, descrive i fondamenti teorici su cui si basa l'intera teoria.

Disclosure, discrimination and desire: experiences of Black and South Asian gay men in Britain

Using findings from a qualitative investigation based on in-depth email interviews with 47 Black and South Asian gay men in Britain, this paper explores the cross-cutting identities and discourses in relation to being both gay and from an ethnic minority background. Taking an intersectional approach, detailed accounts of identity negotiation, cultural pressures, experiences of discrimination and exclusion and the relationship between minority ethnic gay men and mainstream White gay culture are presented and explored. The major findings common to both groups were: cultural barriers limiting disclosure of sexuality to family and wider social networks; experiences of discrimination by White gay men that included exclusion as well as objectification; a lack of positive gay role models and imagery relating to men from minority ethnic backgrounds. Among South Asian gay men, a major theme was regret at being unable to fulfil family expectations regarding marriage and children, while among Black gay men, there was a strong belief that same-sex behaviour subverted cultural notions related to how masculinity is configured. The paper concludes by highlighting the importance of social location, particularly education and income, when examining the intersection of ethnicity and sexuality in future research.
