Relationships of loneliness and mobile phone dependence with Internet addiction in Japanese medical students  [PDF]
Satoko Ezoe, Masahiro Toda
Open Journal of Preventive Medicine (OJPM) , 2013, DOI: 10.4236/ojpm.2013.36055
Abstract: We investigated factors contributing to Internet addiction in 105 Japanese medical students. The subjects were administered by a self-reporting questionnaire designed to evaluate demographic factors, Internet addiction, loneliness, health-related lifestyle factors, depressive state, patterns of behavior, and mobile phone dependence. Results of multivariate logistic regression analysis indicated that loneliness and mobile phone dependence were positively related to degree of addiction. Our findings suggest that Internet addiction is associated with loneliness and mobile phone dependence in Japanese students.
Reciprocity of mobile phone calls  [PDF]
Lauri Kovanen,Jari Saramaki,Kimmo Kaski
Physics , 2010,
Abstract: We present a study of the reciprocity of human behaviour based on mobile phone usage records. The underlying question is whether human relationships are mutual, in the sense that both are equally active in keeping up the relationship, or is it on the contrary typical that relationships are lopsided, with one party being significantly more active than the other. We study this question with the help of a mobile phone data set consisting of all mobile phone calls between 5.3 million customers of a single mobile phone operator. It turns out that lopsided relations are indeed quite common, to the extent that the variation cannot be explained by simple random deviations or by variations in personal activity. We also show that there is no non-trivial correlation between reciprocity and local network density.

Physics , 2011, DOI: 10.1088/0031-9120/46/3/005
Abstract: A Faraday cage is an interesting physics phenomena where an electromagnetic wave can be excluded from a volume of space by enclosure with an electrically conducting material. The practical application of this in the classroom is to block the signal to a mobile phone by enclosing it in a metal can! The background of the physics behind this is described in some detail followed by a explanation of some demonstrations and experiments which I have used.
Mobile Phone Location Tracking by the Combination of  [cached]
Pornpen Ratsameethammawong,M.L.Kulthon Kasemsan
Communications of the IBIMA , 2010,
Abstract: This research introduced the latest method of tracking and locating of client-based mobile phone which will eliminate the limitation of the build-in GPS phone. It has been known that GPS usage is limited in buildings and places unreachable by satellite signal. In order to find better and more accurate results, the method of integrating Wi-Fi signal, cell locations and vector calculation to track and locate mobile phone whereabouts are introduced. Furthermore, it would also be beneficial to develop this method to be applied with other utility programs e.g. delivery truck tracking system or personal locating system via mobile phone.

Mobile Phone and Pakistani Youth:A Gender perspective  [cached]
Zarqa Shaheen Ali
Journal of Telematics and Informatics , 2013, DOI: 10.12928/jti.v1i2.939
Abstract: This research was designed to open a window on youngsters’ use of mobile phone. The present study examined the purposes and patterns of usage of mobile phone use– in both male and female students of undergraduate and graduate level at seven public sector universities of the Province of Punjab (Pakistan). The study examined and reviewed the literature to understand the patterns and purposes of mobile phone use from a global perspective in both developed and developing societies. This provided in a context for the study of mobile phone use in the local Pakistani situation. The findings of the study conclude that gender differences exist in purposes and patterns of usage of mobile phone use, though they are not very significant. There is a change in the trend among females as the usage of the mobile phone is increasing. Contrary to the general perception about gender conscious Pakistani society, females are almost on par with males in using mobile phone. However, existing gender stereotypes maintain the status quo in terms of purposes of using mobile phone.
Expectations And Perceptions Of Mobile Phone Users  [cached]
Sulekha Munshi
International Journal of Asian Social Science , 2011,
Abstract: The main objective of the undertaken research is to study the Expectations andPerceptions of Customer’s towards mobile phones. It is important to study andanalyze whether there is a gap in the expectations and perceptions of therespondents which indicates that there is scope for improvement on behalf of the mobile phone brand or there is no significant difference between the expectations and perceptions of the respondents which is indicative of the fact that the customers are satisfied with the services of their mobile phone provider. The tool used for data analysis in this research has been the Z-Test whereby it is found that there is a significant difference in the expectations and perceptions of the respondents which leads us to believe that the customers are not fully satisfied with the functionality of their handsets.
Supportive intervention using a mobile phone in behavior modification  [PDF]
Hareva,David H.,Okada,Hiroki,Kitawaki,Tomoki,Oka,Hisao
Acta Medica Okayama , 2009,
Abstract: The authors previously developed a mobile ecological momentary assessment (EMA) system as a real-time data collection device using a mobile phone. In this study, a real-time advice function and real-time reporting function were added to the previous system as a supportive intervention. The improved system was found to work effectively and was applied to several clinical cases, including patients with depressive disorder, dizziness, smoking habit, and bronchial asthma. The average patient compliance rate was high (89%) without the real-time advice and higher (93%) with the advice. The trends in clinical data for patients using a mobile EMA with/without the new function were analyzed for up to several months. In the case of dizziness, an improving trend in its clinical data was observed after applying the real-time advice, and in the case of depressive disorder, a stabilizing trend was observed. The mobile EMA system with the real-time advice function could be useful as a supportive intervention in behavior modification and for motivating patients in self-management of their disease.
Exploring the Mobility of Mobile Phone Users  [PDF]

Computer Science , 2012, DOI: 10.1016/j.physa.2012.11.040
Abstract: Mobile phone datasets allow for the analysis of human behavior on an unprecedented scale. The social network, temporal dynamics and mobile behavior of mobile phone users have often been analyzed independently from each other using mobile phone datasets. In this article, we explore the connections between various features of human behavior extracted from a large mobile phone dataset. Our observations are based on the analysis of communication data of 100000 anonymized and randomly chosen individuals in a dataset of communications in Portugal. We show that clustering and principal component analysis allow for a significant dimension reduction with limited loss of information. The most important features are related to geographical location. In particular, we observe that most people spend most of their time at only a few locations. With the help of clustering methods, we then robustly identify home and office locations and compare the results with official census data. Finally, we analyze the geographic spread of users' frequent locations and show that commuting distances can be reasonably well explained by a gravity model.
Emerging aspects of mobile phone use
F Samkange-Zeeb,M Blettner
Emerging Health Threats Journal , 2009, DOI: 10.3134/ehtj.09.005
Abstract: The mobile phone is a modern-day invention, which has managed to reach many parts of the world enabling telecommunications across areas where it was not possible before. Although these devices have proved to be life saving in certain circumstances (e.g., after accidents) and helped improve the quality of life in some sectors, concerns continue to be raised about potential adverse health impacts associated with their use. These range from cancer and cognitive deficiencies to subjective effects, such as a feeling of warmth around the ear used, headache and fatigue. We provide an overview of the concerns raised and summarise what is known about them. We conducted a literature search in Pubmed/Medline to identify published papers on health effects of mobile phones, and an intensive search on the Internet to collect data on the global use of mobile phones. In the year 2000, there were an estimated 500 million mobile phone users worldwide. Today, there are about 3.3 billion users. The use of mobile phones among young children and adolescents is also increasing. Health-risk research has mainly focused on adults and on a single outcome, brain tumours. No significant relationship has been established between mobile phone use and the incidence or growth of brain tumours. Other research indicates emerging concerns, including hearing problems and self-reported health symptoms, such as tiredness, stress, headache, anxiety, concentration difficulties and sleep disturbances, but results remain inconclusive. Currently, there is little epidemiological evidence indicating that the use of mobile phones causes adverse health effects.
