Investigating the role of translators in cross-language qualitative research in psychology

de Vos, Jacqueline January 2018 (has links)
Text in English with abstracts in English, Afrikaans and Tswana. / Academics in social sciences are increasingly conducting research in multilingual contexts. Researchers in the field of cross-language research agree that issues on the role of translators and translation are often neglected and even omitted in research reports, which may affect the trustworthiness of such a study. The aim of this study was to investigate the role of translators in cross-language qualitative research from the views of master’s and doctoral students who conducted cross-language qualitative research in psychology at a selected South African university. Exploratory qualitative research and methodology were deemed suitable for this study. Key participants were sampled through snowball sampling. Five postgraduates availed themselves to participate. Data were collected by semi-structured e-mail, telephone and/or face-to-face interviews. Semi-structured interviews were audio recorded and transcribed by the researcher after the interviews. As the number of available participants was limited, the researcher also sampled unpublished dissertations (5) and doctoral theses (2) to conduct document analysis. Transcripts were imported into ATLAS.ti™, whereafter the qualitative data were analysed by means of thematic data analysis. Five main themes emerged from the data. Themes from the transcripts as well as notes in the researcher’s reflective journal and relevant literature findings were collated. Finally, a critical discussion was provided. Key participants believed that translators may play a significant role in several stages of a cross-language qualitative study. Participants reported experiencing several translation challenges, namely: language barriers between them and their research participants; difficulty translating subject terminology from English into Afrikaans; and outdated bilingual scientific dictionaries. Findings also revealed that the credentials of the translator hired may have an impact, whether positive or negative, on the translation product. Reasons why translators may be excluded from a cross-language qualitative study were also highlighted. Firstly, although some of the participants reported that translators may be valuable in a cross-language study, all of them strongly asserted that they possessed high language competency, and therefore they deemed the inclusion of translators unnecessary. v It also emerged that qualitative researchers may need to be cognisant of ethical issues that may arise in a cross-language study. Translators may further be excluded as translation may not be suitable for the specific research design (for example, phenomenology). Finally, researchers may not have the financial means to hire translators. None of the key participants reported the language/translation challenges they experienced during their studies and the possible impact it may have had on the methodology or quality of data. They did not deem it an important aspect of their studies. In some of the dissertations and theses sampled, only the mother tongue of participants was often indicated but, in most cases, was discussed very superficially. These researchers mostly mentioned (as part of the biographic information) the language profile of their participants; that the data for that study were collected in either Afrikaans or English; and that the data were translated and analysed. Finally, although some of the sampled research reports were edited by professional language practitioners, translation and grammatical errors were clear throughout in the manuscripts. From this research it was clear that including translators in cross-language qualitative research in psychology is not a common practice in the South African context, and matters relating to translation and how challenges in this regard were dealt with are grossly neglected and mostly omitted in postgraduate research reports. To conclude, limitations of this study were highlighted, and recommendations for future translation research and practice were made. Keywords:; / Navorsing in sosiale wetenskappe word toenemend in veeltalige kontekste uitgevoer. Kruistaal kwalitatiewe navorsers is dit eens dat vraagstukke rondom die rol van vertalers en vertaling gereeld oor die hoof gesien word en selfs in navorsingsverslae uitgelaat word, wat uiteindelik die vetrouenswaardigheid van so ʼn studie mag affekteer. Hierdie studie het ten doel gehad om ondersoek in te stel na die rol van vertalers in kruistaal kwalitatiewe navorsing vanuit die oogpunt van meestersgraad- en doktorale studente wat kruistaal kwalitatiewe navorsing in sielkunde aan ʼn gekose Suid-Afrikaanse universiteit uitgevoer het. Eksploratiewe kwalitatiewe navorsing en metodologie is as geskik geag vir hierdie studie. Sleuteldeelnemers is deur middel van sneeubalsteekproefneming gekies. Vyf nagraadse studente het hulleself beskikbaar gestel om aan die navorsing deel te neem. Data is deur middel van semi-gestruktureerde e-pos-, telefoon- en aangesig-tot-aangesig-onderhoude ingesamel. Die aantal deelnemers wat aan die studie kon deelneem was beperk en daarom het die navorser ook ongepubliseerde verhandelings (5) en proefskrifte (2) ingesamel ten einde dokumentanalise uit te voer. Transkripsies is in ATLAS.ti™ ingevoer, waarna die kwalitatiewe data deur middel van tematiese data-analise ontleed is. Vyf hooftemas het uit die data gespruit. Temas uit die transkripsies sowel as die navorser se notas uit haar reflektiewe joernaal en relevante literatuurbevindinge is saamgevat, waarna ʼn bespreking gevolg het. Sleuteldeelnemers was van mening dat vertalers ʼn belangrike rol kan speel in verskeie fases van ʼn kruistaal kwalitatiewe studie. Volgens deelnemers het hulle verskeie vertaaluitdagings ervaar, naamlik: taalhindernisse tussen hulle (die navorser) en hul navorsingsdeelnemers; uitdagings om vakterminologie van Engels in Afrikaans te vertaal; en verouderde tweetalige vakwoordeboeke. Bevindinge het ook getoon dat die aangestelde vertaler se kwalifikasies ʼn impak mag hê, hetsy positief óf negatief, op die vertaalproduk. Redes waarom vertalers van ʼn kruistaal kwalitatiewe studie uitgesluit kan wees, is ook uitgelig. Ten eerste, hoewel enkele deelnemers meegedeel het dat vertalers in ʼn kruistaal kwalitatiewe studie waardevol kan wees, het alle deelnemers sterk benadruk dat hulle oor hoë taalvaardigheid beskik, en daarom het hulle die insluiting van vertalers in hul studies vii onnodig geag. Dit blyk ook dat kwalitatiewe navorsers bewus moet wees van etiese vraagstukke wat in ʼn kruistaal studie mag onstaan. Vertalers kan voorts uitgesluit word indien vertaling nie geskik is vir die spesifieke navorsingsontwerp nie (byvoorbeeld, fenomenologie). Laastens, navorsers beskik moontlik nie oor die finansiële middele om vertalers aan te stel nie. Geeneen van die sleuteldeelnemers het die taal- of vertaaluitdagings wat hulle in hul studies ervaar het, genoem nie en het ook nie gemeld wat die moontlike impak op die metodologie of kwaliteit van die data mag wees nie. Hulle het dit nie in hulle studies belangrik geag nie. In enkele gekose verhandelings en proefskrifte is die moedertaal van navorsingsdeelnemers in daardie studies aangedui, maar is meestal baie simplisties bespreek. Hierdie navorsers het grotendeels slegs die taalprofiel van hulle deelnemers genoem (as deel van die biografiese inligting); dat data in hulle studies in óf Engels óf Afrikaans ingesamel is; en dat die data vertaal en ontleed is. Laastens, hoewel sommige van die navorsingsverslae deur professionele taalpraktisyns geredigeer is, is vertaal- en grammatiese foute steeds deurgaans in die manuskripte opgemerk. Dit blyk duidelik uit dié navorsing dat die insluiting van vertalers in kruistaal kwalitatiewe navorsing in sielkunde nie algemene praktyk in die Suid-Afrikaanse konteks is nie, en sake wat verband hou met vertaling en hoe uitdagings in dié verband hanteer is, word grootliks nagelaat en meestal in nagraadse navorsingsverslae uitgelaat. Ten laaste is beperkings van die studie uitgelig, en aanbevelings is gemaak vir toekomstige vertaalnavorsing en -praktyk. / Batlhatlheledi mo dithutong tsa maaranyana a dikgolagano gareng ga batho ba ba dirang patlisiso ka ga bopuontsi, ba ntse ba oketsega go feta.

La contribution des Français à l'étude du swahili : le cas de Charles Sacleux (1856-1943) / French scholars’ contributions to the study of the Swahili language : the case of Charles Sacleux (1856-1943)

Mtavangu, Norbert 05 December 2013 (has links)
Le swahili, avec presque 100 millions de locuteurs, est la langue bantu la plus dispersée, étudiée,diffusée et la plus importante. Cette langue officielle de la Tanzanie, du Kenya et de l’Ouganda est aussi une langue de fonctionnement de l’Union Africaine. Le swahili qui a absorbé un important lexique du monde arabe, fruit des interactions commerciales et sociales séculaires continue à adopter de plus en plus de termes anglais en conséquence de la colonisation et du développement en science et en technologie. Du fait que sa description fut dirigée et influencée par les Anglais et les Allemands, le rôle des Français fut négligé et écarté, laissant l’histoire du swahili incomplète.Pourtant, la contribution des Français à l’étude du swahili n’est pas négligeable, tout d’abord par l’œuvre des missionnaires de la Congrégation du Saint-Esprit et les Pères Blancs dès le XIXe siècle, puis depuis 1960 par les travaux menés en France par les enseignants/chercheurs de cette langue. La recherche effectuée à partir des archives ainsi que des interviews faites pour le compte de la présente étude montrent que le spiritain Charles SACLEUX joua un rôle considérable dans l’étude du swahili.Les documents rédigés par ce polyglotte et botaniste, dont le monumental dictionnaire swahili français(1939) révèlent des informations rares surtout en étymologie, lexicographie,dialectologie et ethnolinguistique ainsi qu’une perspective intégrale et descriptive contrairement à ses contemporains qui se servaient de la méthode prescriptive. Il est donc souhaitable que les dictionnaires de SACLEUX soient réétudiés et intégrés dans le swahili standard. / Following a research undertaken in archives, libraries as well as through interviews, the author describes the Swahili coast and the contact between Swahili and Europeans. While analyzing available early documents published by French researchers, he chronologically depicts endeavour and challenges of studying African languages during that era. Among them, Charles SACLEUX, a Spiritan priest performed an outstanding work especially in etymology, dialectology, lexicography and in ethno-linguistics. The study presents his biography together with his philosophical and methodological approaches. The findings show that in comparison with other researchers who, for the sake of standardizing the language, used a prescriptive approach, he opted for a descriptive. His publications present the language in its natural state. Together with Sacleux’ work, to complete the account, the thesis reserves one chapter for the current progress in teaching/learning as well as publishing on Swahili in France. The insights from the study suggest that it is important that some contents from Sacleux’ publications be revised and incorporated in contemporary Swahili literature.
