A case-case study of mobile phone use and acoustic neuroma risk in Japan

Although mobile phones have proved to be lifesaving in certain circumstances, wide concerns have been raised about brain tumors associated with their use. This article systematically reviews previous and current research in regards to mobile phone use and brain tumors. Recently, research (more than 10 years mobile phone use or cumulative mobile phone use more than 1640 hours) has been found that the amount of exposure to mobile phone radiation plays a key role in determining the significant associations between mobile phone use and gliomas, and acoustic neuroma. In general, those who use mobile phones for more than ten years, or cumulative call time for more than 1640 hours, have higher risks to develop brain tumors, especially glioma and acoustic neuroma, than those who use mobile phones for less than one year.

Mobile Phone Usage

Mobile phone use among university students is now pervasively altering their social interaction with others. The study investigated the influence of mobile phone use among commuting University Students on their interaction with co-travellers and the environment through which they travel. Three hundred students of Obafemi Awolowo University, Ile-Ife, Nigeria were purposively sampled to respond to a 10-minute questionnaire. The questionnaire contained questions such as ownership of mobile phones, type and number of phones owned, frequency of usage and the influence of mobile phone usage during transit on interaction between the students and their co-travelers and with the environment they traveled through. Results showed that all the respondents possessed at least one mobile phone. In addition, results revealed a negative correlation between time of use of mobile phone and interaction with co-travelers (α=0.05, r= -0.039) and no significant correlation between length of use of mobile phone and interaction with the environment (α=0.05, r=0.079). The study established that mobile phone intrusiveness has an influence on students' interaction during commuting.

Coverage Problems

In 2004, the number of mobile phone subscriptions in Slovenia reached the total number of inhabitants. Consequently, the fixed telephone coverage has started to decline; almost 10% of households are now available only over the mobile phone. With this, Slovenia positions itself as a typical EU country and can serve as a case study for issues related to mobile phone interview surveys. The paper addresses the general context of mobile phone usage and the calculations of mobile phone coverage rates. It also discusses the non-coverage problems related to mobile and mobile-only households. It is shown, that even with a relatively small non-coverage the corresponding estimates can be considerably biased, as in the case of the unemployment rate in the Slovenian Labour Force Survey. There are severe methodological problems with mobile phone interview surveys. In particular, a pilot mobile phone survey confirmed the disadvantages of costs, frames and response rates, at least when compared to fixed telephone surveys. In addition, the response rates are dramatically lower for less intensive mobile phone users. The comparisons of respondents in mobile phone surveys with the corresponding sub-samples in Labour Force Surveys and in fixed telephone surveys revealed some specific discrepancies in the socio-demographic structure. Due to non-coverage, the respondents in the mobile phone survey tend to be younger, higher educated, from larger households and are represented by a larger share of males. The non-response mechanism can additionally reinforce these effects (e.g, gender), however it can also cancel them (e.g., age, household size). Special complexity arises from the diverse effects of the non-response components (refusal vs. non-contact). According to their attitudes towards mobile phone use, mobile phone users compose three distinct segments (intensive pragmatic and emotional users, less intensive users) that may behave differentially also during the mobile phone survey process.

Mobile Phone Usage

Mobile phones are now being used by all members of society, men, women and the children. When members of society use them it affects their lives, thus the research is interested in exploring how mobile phone usage affects the lifestyles of female university students. The study explored the dependency and effect of mobile phone usage among female students at a university of technology. A cross-sectional survey was carried at Tshwane University of Technology (TUT), Soshanguve South campus. The study focused on the following objectives: exploring the classification of female university students who own cell phones, establishing the general phenomena influencing the use of mobile phones by female university students at a university of technology and perceived gratification and finally establishing the patterns of mobile phone use by female students and the lifestyle patterns generated thereafter. The study collected data from 100 female students at the institution using a survey. The findings indicated that the main reasons female university students at TUT use a mobile phone are for socialising, sharing academic work and solutions as well as for safety and privacy purposes. The major reason for choice of brand was seen to be usability and price. The respondents showed some signs of addiction to their mobile phones. The findings of this study are beneficial to marketers of mobile phones in Pretoria and the rest of the country; it is also useful to mobile phone developers, universities, parents, and researchers exploring mobile phone adoption and usage pattern in a developing country such as South Africa.
