Mobile New Zealand : a multi-method comparative study of cell phone useBroege, Stephanie, n/a January 2008 (has links)
Worldwide use of mobile phones has created a new basis for interpersonal communication and has become a ubiquitous feature of youth culture. Hence the examination of global mobile phone adoption is a global challenge for communication researchers as well as for the media industries. Thus far, New Media research in New Zealand (NZ) has focused on children and teenagers. The group of young adults between 18-25 years has rarely been surveyed. This thesis focused on university students� use of mobile communication in NZ in the context of their everyday practices. The Mobile Media Study (MMS) was designed as a cross-national comparative research project with a focus on NZ together with one European and one North American country. The usage behavior, experiences, attitudes, and opinions of young NZers� towards mobile phone use was examined and contrasted to young German and American students. Methodological and data triangulation was applied and data was collected at the University of Otago, the City University of New York, the Pennsylvania State University, and the University of Leipzig. MMS survey research was conducted along with focus group and personal interviews, and qualitative exercises. In addition, the latest data from a longitudinal study of New Media use in Germany, the US and NZ served as a secondary, comparative, and complementary dataset.
The research questions focused on general mobile phone use, text-messaging (SMS), the acceptance of Third Generation (3G) cell phones, mobile phone use in public places, gender-specific usages, and the construction of mobile social networks. Altogether, data from 1,316 students at four universities in three countries was analyzed. Results indicated that the number of providers as well as tariff structures appear to influence mobile phone adoption within a country. To adjust to the duopoly situation young people in NZ preferred prepaid cards in connection with a SMS package. This was reflected by extraordinarily high use of SMS in NZ. By comparison German and American students preferred annual contracts. Americans, who had the strongest preference for mobile calling, also had the highest monthly expenses. Additionally, findings revealed that overall user interest in 3G services is not yet very high. It was found that in particular NZ students do not exploit the full range of mobile services already available to them and feel confident that their current cell phone gratifies all their needs. They concentrate on using basic functions, such as calling and SMS. In addition, results suggest a decreasing role of the landline telephone and email for interpersonal communication.
Gender differences were found with NZ women in particular being most enthusiastic about SMS. German men had the most negative attitude toward SMS and also used the service the least in comparison to the other students surveyed. In general women had a preference for the communicative functions on their mobile phone including voicemail and more women than men in Germany and NZ were found to play mobile phone games. Finally, evidence of gender specific social network structures were found in NZ with male networks resembling spider webs while female networks were centered so that all persons in the network connected back to the center. Overall, students only used a fraction of the contacts in their mobile phone book and communicated mostly within a limited local area. In conclusion, a replication of the MMS was suggested along with further multi-method research in the field of Asian-NZer�s New Media use.

Investigating the impact of SMS speak on the written work of English first language and English second language high school learnersFreudenberg, Kristy 03 1900 (has links)
Thesis (MPhil (General Linguistics))--Stellenbosch University, 2009. / This study examined the impact of SMS speak on the written school work of English first
language (L1) and English second language (L2) high school learners. The general aims of
the study were to establish how widespread the use of SMS language is among high school
learners, and to assess whether there is any evidence of the use of features of SMS speak in
the English written work of these learners.
Eighty-eight learners from an English-Afrikaans dual medium school in a middle class
neighborhood in the Western Cape participated in this study. The participants included 43
grade 8s and 45 grade 11s, of which 51 were English L1 speakers and 37 English L2
speakers. The participants completed questionnaires from which the frequency and volume
of their SMS use was determined, as well as the features of SMS speak they reportedly use
while SMSing. In addition, samples of the learners’ English written work were examined
for specific features of SMS speak. These features included (deliberate) spelling errors,
lack of punctuation, over-punctuation, the omission of function words, the use of
abbreviation or acronyms, and the use of emoticons and rebus writing.
The results of this study indicate that high school learners are avid users of SMS and/or
MXit. All participants reported using features of SMS speak in their SMSes, and many
reported using SMS speak in their written school work. Despite this, the samples of written
work did not contain a great number of incidences of SMS speak features. It seems that the
general lack of SMS speak in the written work of these learners is a result of being able to
assess when it is and is not appropriate to use a certain variety of language: These learners
are proficient in SMS speak and use it when chatting to friends on MXit, but they can
produce written work that adheres to the formally approved standards of written high
school English. That said, a number of SMS speak features were indeed present in their
formal written work, which indicates that SMS speak had some impact on the written work
of these learners, which could in turn be attributed to the high frequency of their SMS
usage. However, not all of the non-standard features of their written English could
necessarily be attributed to the influence of SMS speak; specifically some of the spelling
and punctuation errors could be unrelated to SMS speak, as they have been noted in the
written English of high school learners from before the advent of cellphones.
The learners in this study were from a school that has a strict language policy, one which
does not tolerate the use of SMS speak in written work. Seven of the teachers completed a
questionnaire compiled for all teachers at the school in question. Responses to this
questionnaire, especially those of the language teachers, indicated that teachers either
deduct marks for features of SMS speak in written language or refuse to mark written work
that does not conform to the formally approved standards that the school has set in place. It
is possible that the actions of the teachers and the language policy of the school play a
significant role in the lack of SMS speak features in the written language use of the
learners.
