Mobile phones offer a new marketing channel, but socially there are concerns about their intrusiveness. Marketers need to understand the social etiquettes governing their use in order to exploit their value. In addition, the use of mobiles whilst driving is the cause of car accidents and is illegal in some parts of the world. A study of 893 United States, Australian and Chinese tertiary students showed that there was widespread but not universal agreement that usage was inappropriate in places of worship, classrooms and libraries or while driving a car. Australian and Chinese students were more tolerant of mobile usage than Americans in most situations, apart from use while driving. The study showed a conflict between actual driving behaviour and views on the desirability of using mobiles while driving. The persistence of talking while driving should be a concern to those who promote road safety. Use of SMS was more broadly tolerated in class and in picture theatres than was speaking on a mobile phone. The use of inbound and outbound telemarketing is limited by the social etiquettes discovered. Further research into tolerable mobile behaviour in various public and private spaces is required in order to make best use of this marketing medium.

This study investigates journalism students’ usage of mobile phone technology when they begin their university studies and considers the implications of these baseline data for journalism education. This paper reports on the findings of three consecutive annual surveys of first year journalism students about their use of the applications available on their mobile phones. The surveys confirm that as well as using their phones to text and call, many are making video calls and most have shot photos and videos on their phones by the time they arrive at university. Many are using their phones to send or publish these images. More than half of the students now go online on their mobile phones. This evidence will inform journalism educators seeking to update their teaching practices and curricula.

Mobile computing devices such as personal digital assistants, smart mobile phones, and other handheld computing devices hold much promise in terms of their organizational application. Many existing models of the individual acceptance and implementation of information technology in organizational contexts have been developed in the era of “at the office” computing such as MIS, office automation, groupware, and so forth. We conducted two in-depth case studies of the implementation of mobile technology in healthcare organizations. The studies highlight interrelated individual use contexts due to the mobility of the technology: the individual as employee, as professional, as private user, and as member of society. The cases show that influences emanating from these use contexts impacted on the individual adoption of the technology within the organization. While broad extra-organizational influences are incorporated in some existing individual technology adoption models, we show that it becomes relevant to accommodate these influences more specifically in research models of mobile computing in organizations. Based on the extant literature and the case study data we pave the way toward more comprehensive models of the adoption and implementation of mobile technologies in organizations.

Farmers living in rural villages of Sri Lanka do not have proper access to information to make informed decisions about their livelihoods and as a result they face constant hardships in their lives. They use mobile phones to communicate but these are not currently connected to the Internet. We are investigating how to provide personalized information to farmers with the aim of empowering them to make informed decisions and take appropriate actions. In this paper we propose an empowerment model that has been designed to achieve their goals which have been identified using a scenario-based approach. The model examines several empowerment processes and supporting tools that would help them to achieve their goals with the hope that they would have an increased sense of control, self-efficacy, knowledge and competency. This empowerment model is applied to the development of a mobile based information system that is being developed by an international collaborative research group to address the issues of the farmers.

Gambling prevalence studies are typically conducted within a single (landline) telephone sampling frame. This practice continues, despite emerging evidence that significant differences exist between landline and mobile (cell) phone only households. This study utilised a dual-frame (landline and mobile) telephone sampling methodology to cast light on the extent of differences across groups of respondents in respect to demographic, health, and gambling characteristics.

A total of 2,014 participants from across Australian states and 
territories ranging in age from 18 to 96 years participated. Interviews were conducted using computer assisted telephone interviewing technology where 1,012 respondents from the landline sampling frame and 1,002 from the mobile phone sampling frame completed a questionnaire about gambling and other health behaviours. Responses across the landline sampling frame, the mobile phone sampling frame, and the subset of the mobile phone sampling frame that possessed a mobile phone only (MPO) were contrasted.

The findings 
revealed that although respondents in the landline sample (62.7 %) did not significantly differ from respondents in the mobile phone sample (59.2 %) in gambling participation in the previous 12 months, they were significantly more likely to have gambled in the previous 12 months than the MPO sample (56.4 %). There were no significant differences in internet gambling participation over the previous 12 months in the landline sample (4.7 %), mobile phone sample (4.7 %) and the MPO sample (5.0 %). However, endorsement of lifetime problem gambling on the NODS-CLiP was significantly higher within the mobile sample (10.7 %) and the MPO sample (14.8 %) than the landline sample (6.6 %).

Our research 
supports previous findings that reliance on a traditional landline telephone sampling approach effectively excludes distinct subgroups of the population from being represented inresearch findings. Consequently, we suggest that research best practice necessitates the use of a dual- rame sampling methodology. Despite inherent logistical and cost issues, this approach  needs to become the norm in gambling survey research.

Mobile learning is considered to be an advanced stage of E-learning. Mobile devices supported learning provides teaching materials anytime, anywhere, and eliminates space and time constraints for learners. Mobile devices-supported learning includes all portable devices such as mobile phones, PDAs, tablet PCs, and e-books. This paper aims to investigate the issue from a different perspective. Firstly, we consider how many novice programmers have personal mobile devices and what type of mobile devices they are using (PDA, tablet PC, e-book). Secondly, we consider whether the Buraimi University College (Oman) Information Technology infrastructure supports mobile learning. Thirdly we consider students' behavior and attitude towards mobile devices supported teaching materials. For this purpose, the survey method will be used as a research tool to collect responses from 1st year students enrolled in introductory programming courses at the Information Technology department of Buraimi University College. This paper also describes a set of findings which helps instructors to take steps to promote mobile learning for novice programmers.

Background: New technology such as the internet and mobile phone applications (“apps”) are increasingly being used in clinical practice. However, little is known in regards to individual’s attitudes towards medical professionals using the internet and apps in the context of their own medical care. The aim of the present study was to examine and compare individual’s attitudes towards the use of medically related internet sites and apps in clinical practice. 


Method: Participants completed an on-line survey which contained questions regarding their own use of mobile phones and the internet, their use of healthcare facilities, and their attitudes towards medical professionals using the internet and apps during consultations. Attitudes were assessed by asking participants to rate 11 statements on a 5 point scale. 

Results: The survey was completed by 141 individuals. All participants owned a mobile phone, with 82% owning one with application support. Furthermore, all participants had access to the internet at home. Generally participants had more favourable attitudes towards medical professionals using the internet than apps. For example, participants found it more acceptable for doctors to use medically related internet sites than mobile phone apps during consultations with patients.

Conclusion: It is possible that attitudes towards the internet were more favourable than that for apps because the internet has been available longer and consequently individuals are more familiar with it. Prior to using newer electronic resources, especially apps, medical professionals should adequately inform patients in regards to their intended use to avoid potential misconceptions.

Background
Mobile health (mHealth) behaviour change programmes use mobile phones and the internet to deliver health information and behaviour change support to participants. Such programmes offer a potentially cost-effective way to reach many individuals who do not currently access weight loss services. We developed a mHealth weight management programme using proven face-to-face behaviour change techniques and incorporating target population input. Our aim was to evaluate the feasibility, acceptability and potential effectiveness of this programme for ethnically diverse adults with a view to informing a larger trial.

Results
Fifty three adults who had a BMI of ≥25 kg/m2 and wanted to lose weight (81% female, mean age 42 years, mean BMI 35.7 kg/m2, 26% Maori, 34% Pacific) received the eight-week mHealth weight loss programme. Anthropometric measures were taken at two face-to-face assessments at baseline and 12-weeks (i.e. four weeks after cessation of intervention).

Twelve-week follow-up measurements were available for 36/53 participants (68%). Non-completers were younger and more likely to be male and of Pacific ethnicity. Thirty five participants (66%) reported reading ‘all or most’ text messages sent and 96% responded to at least one text data collection question over the eight-week active intervention period. Eighty one per cent of participants logged in to the study website at least once during the eight-week study period. In the intention-to-treat analysis, mean weight change was -1.0 kg (SD 3.1) at 12 weeks (p = 0.024) and change in BMI was -0.34 kg/m2 (SD 1.1) (p = 0.026). In the completers only analysis (n = 36), mean weight change was -1.4 kg (SD 3.6) (p = 0.023) and change in BMI was -0.50 kg/m2 (SD 1.3) (p = 0.025).

Conclusions
A mHealth weight management programme is feasible to deliver to an ethnically diverse population. Changes in body weight and BMI at 12 weeks indicate that the programme could be effective in supporting people with weight loss. However, the high dropout rate indicates a need for further improvements to the programme.

Around one billion people access the Internet using their mobile phones today, and many of the mobile phones are prone to be compromised by hackers due to their inherited vulnerability. It is critical to identify these compromised mobile phones to effectively eliminate cyber attacks. However, we see few research works in the field. In order to address this desperate situation, we design a practical traceback framework to identify active compromised mobiles in the mobile Internet environment in this letter. In the proposed framework, we creatively use the IMEI number of mobile hardware as unique marks for the traceback purpose. Two-layer traceback tables are designed to collect global attack information and identify local attacking bots, respectively. Our analysis and simulation demonstrate that the proposed traceback method is effective and feasible, and it can identify every possible attacking mobile in the current mobile Internet environment with single packet marking.

BACKGROUND: Childhood obesity is an increasing health problem globally. Overweight and obesity may be established as early as 2-5 years of age, highlighting the need for evidence-based effective prevention and treatment programs early in life. In adults, mobile phone based interventions for weight management (mHealth) have demonstrated positive effects on body mass, however, their use in child populations has yet to be examined. The aim of this paper is to report the study design and methodology of the MINSTOP (Mobile-based Intervention Intended to Stop Obesity in Preschoolers) trial.

METHODS/DESIGN: A two-arm, parallel design randomized controlled trial in 300 healthy Swedish 4-year-olds is conducted. After baseline measures, parents are allocated to either an intervention- or control group. The 6- month mHealth intervention consists of a web-based application (the MINSTOP app) to help parents promote healthy eating and physical activity in children. MINISTOP is based on the Social Cognitive Theory and involves the delivery of a comprehensive, personalized program of information and text messages based on existing guidelines for a healthy diet and active lifestyle in pre-school children. Parents also register physical activity and intakes of candy, soft drinks, vegetables as well as fruits of their child and receive feedback through the application. Primary outcomes include body fatness and energy intake, while secondary outcomes are time spent in sedentary, moderate, and vigorous physical activity, physical fitness and intakes of fruits and vegetables, snacks, soft drinks and candy. Food and energy intake (Tool for Energy balance in Children, TECH), body fatness (pediatric option for BodPod), physical activity (Actigraph wGT3x-BT) and physical fitness (the PREFIT battery of five fitness tests) are measured at baseline, after the intervention (six months after baseline) and at follow-up (12 months after baseline).

DISCUSSION: This novel study will evaluate the effectiveness of a mHealth program for mitigating gain in body fatness among 4-year-old children. If the intervention proves effective it has great potential to be implemented in child-health care to counteract childhood overweight and obesity.
