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.

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.

BACKGROUND No study has comprehensively investigated the association between the usage of typical screen-based electronic media devices and sleep quality in a Chinese population with individuals in a wide range of ages. OBJECTIVE This study aimed to understand the characteristics of television (TV) viewing, computer usage, and mobile phone usage in a representative Chinese population in Macau and to examine their roles in predicting the variations in sleep quality. METHODS This cross-sectional study was an analysis of 1500 Macau residents aged 15 to 90 years based on a community-based health needs assessment study entitled, “Healthy Living, Longer Lives.” Data collection was conducted in 7 districts of Macau from 2017 to 2018 through face-to-face interviews. The durations of daily TV viewing, computer usage, and mobile phone usage were recorded in a self-administered questionnaire. The Chinese version of the Pittsburgh Sleep Quality Index (PSQI) was used to assess the sleep quality. RESULTS The prevalence of TV, computer, and mobile phone usage was 78.4% (1176/1500), 51.6% (769/1490), and 85.5% (1276/1492), respectively. The average daily hours of usage were 1.75 (1.62), 1.53 (2.26), and 2.85 (2.47) hours, respectively. Females spent more time watching TV (<i>P</i>=.03) and using mobile phones (<i>P</i>=.02) and less time on the computer (<i>P</i>=.04) as compared to males. Older adults were more likely to watch TV while young people spent more time using the computer and mobile phones (<i>P</i> for all trends&lt;.001). The mean PSQI global score was 4.79 (2.80) among the participants. Females exhibited significantly higher PSQI scores than males (5.04 vs 4.49, respectively; <i>P</i>&lt;.001). No linear association was observed between the PSQI score and the amount of time spent on the 3 electronic devices (<i>P</i>=.58 for PSQI-TV, <i>P</i>=.05 for PSQI-computer, and <i>P</i>=.52 for PSQI-mobile phone). Curve estimation showed significant quadratic curvilinear associations in PSQI-TV (<i>P</i>=.003) and PSQI-computer (<i>P</i>&lt;.001) among all the participants and in PSQI-mobile phone among youths (age, 15-24 years; <i>P</i>=.04). After adjustment of the gender, age, body mass index, demographics, and lifestyle factors, more than 3 hours of TV viewing and 4 hours of computer usage or mobile phone usage was associated with 85% (95% CI 1.04-1.87; <i>P</i>=.008), 72% (95% CI 1.01-2.92; <i>P</i>=.045), and 53% (95% CI 1.06-2.22; <i>P</i>=.03) greater odds of having poor sleep quality (PSQI score&gt;5), respectively. CONCLUSIONS The mobile phone was the most popular screen-based electronic device used in the Macau population, especially among young people. “J” shape associations were observed between sleep quality and the duration of TV viewing, computer usage, and mobile phone usage, indicating that the extreme use of screen-based electronic devices predicted poorer sleep status, whereas moderate use would be acceptable.

Uncertainty about the association between health risks and exposure to radiofrequency radiation emitted by cellular and cordless mobile phones can be addressed by a critical analysis of the methodology used in studies assessing this relationship. Studies funded by cellphone companies give reassuring conclusions but are affected by biases and flaws, whereas public-funded studies are without these errors and show acute and chronic effects, including head tumors, findings supported by biological evidence.

Ever since the discovery of the Mandelbrot set, the use of computers to visualise fractal images have been an essential component. We are looking at the dawn of a new age, the age of ubiquitous computing. With many countries having near 100% mobile phone usage, there is clearly a potentially huge computation resource becoming available. In the past years there have been a few applications developed to generate fractal images on mobile phones. This chapter discusses three possible methodologies whereby such images can be visualised on mobile devices. These methods include: the generation of an image on a phone, the use of a server to generate the image and finally the use of a network of phones to distribute the processing task.

<p>Due to today’s interconnected and technology-driven world, a physical learning environment is transforming into a virtual or online location where learners can make active learning with portable devices. There is no doubt that an increasing number of students, who have mobile devices which handle digital information and facilitate their mobility. As an integral part of students’ daily lives, the universities and schools in higher education are also trying to equip with technology‘s changes and to solve the demand of their learners, and to adopt m-learning. This study learns the mobile phone usage of Myanmar student. In addition, it constructs a key part which investigates the students’ m-learning readiness and evaluates the influences on their attitudes to use m-learning. And a hypothesized model was introduced to investigate learners’ readiness to adopt m-learning. The empirical study is conducted by analyzing data collected as paper-based documents from 1024 participants. The findings advocate the eleven hypotheses which have positive impact to students’ m-learning readiness and their intension to use m-learning.</p>

Background: The introduction of new technologies into the medical field has the duality of improvement and concerns about correct usage and cleaning. Mobile phones are used by healthcare professionals (HCPs) in the work place, and there is not an official policy about their use in health environment. Methods: We asked 60 intensive care unit (ICU) HCPs from 2 units (the burn unit and the internal medicine unit) to participate in an electronic survey about mobile phone usage and hand hygiene compliance; we also cultured the hands and mobile phones of the participants. Unfortunately, 13 HCPs did not participate. Susceptibility testing of the strains was conducted, as well as molecular testing. Results: Overall, 47 HCPs responded to the inquiry: 19% were nurses (9 of 47), 19% were resident physicians (9 of 47), 17% were nursery technicians (8 of 47), 17% were physiotherapists (8 of 47), 13% were cleaning staff (6 of 47), 11% were consultants (5 of 47), and 4% were technicians (2 of 47). Moreover, 26 of 47 participants (55%) were woman and 21 (45%) were men. From all HCP categories, 39 of 47 respondents (83%) reported that they had optimal hand hygiene compliance. However, 92% of respondents had a colonized hand and 90% had a colonized mobile phone. Also, 44 of 47 HCPs (94%) reported that the took their personal mobile phone into the workplace; 40 (85%) reported that they used it during the work day and 35 (74%) reported that they cleaned it. However, 8 HCPs (26%) reported that they had never cleaned the device. All of the HCPs understood that mobile phones can harbor bacteria, and 27 of 47 HCPs (57.45%) indicated that they use 70% alcohol to clean their mobile phones. In contrast, the first choice for hand hygiene was water and soap in 51% of HCPs (24 of 47). Also, 3 HCPs did not have any colonization in the hand culture but had healthcare-associated infection (HAI) pathogens in the mobile phone culture. Conclusions: A policy regarding mobile phone usage in the healthcare setting should be in place, and cleaning of electronic devices in hospitals should be standardized.Funding: NoneDisclosures: NoneFunding: NoneDisclosures: None

Purpose – The purpose of this paper is to critically analyze the discourses on migrant acculturation and migrants’ mobile phone communication, in order to examine the inclusiveness of communication-acculturation research in the recent years. Design/methodology/approach – The paper draws on from 102 qualitative interviews (48 Malayali, 26 Bangla, 17 Tamil and 11 Telugu) for a larger research project that investigated the role of mobile phones in migrant acculturation in Singapore. Respondents were selected using a combination of purposive and snowball sampling methods. The respondents had been in Singapore for varying amount of time: from one month to 19 years. Findings – The analysis of the discourses on migrant acculturation and mobile phone communication revealed that labor migrants were excluded on the basis of their temporary status and apprehensions on work productivity. The mobile usage prohibitions that existed in work sites were hinged on similar discourses that stereotyped the labor migrants. The emancipatory metaphor that has been at the center of research on migrants’ mobile phone usage and acculturation needs to be replaced with a critical discourse perspective. Research limitations/implications – The data were originally collected for a research project that approached the phenomena of acculturation and mobile phone appropriation from a positivist perspective, whereas this paper analyzed the data to critically examine the discourses that supported the premise of the project itself. Due to this, the findings presented in this paper have limited scope for generalization. Originality/value – The paper critiques the research trends in migrant acculturation and mobile phone communication and suggests a possible alternative that goes beyond the “transcendental teleology” that underpins discourse and practice.
