In this paper, we propose a secure object tracking protocol to ensure the visibility and traceability of an object along the travel path to support the Internet of Things (IoT). The proposed protocol is based on radio frequency identification system for global unique identification of IoT objects. For ensuring secure object tracking, lightweight cryptographic primitives and physically unclonable function are used by the proposed protocol in tags. We evaluated the proposed protocol both quantitatively and qualitatively. In our experiment, we modeled the protocol using security protocol description language (SPDL) and simulated SPDL model using automated claim verification tool Scyther. The results show that the proposed protocol is more secure and requires less computation compared to existing similar protocols.

BACKGROUND: Despite the health benefits of regular physical activity, most children are insufficiently active. Schools are ideally placed to promote physical activity; however, many do not provide children with sufficient in-school activity or ensure they have the skills and motivation to be active beyond the school setting. The aim of this project is to modify, scale up and evaluate the effectiveness of an intervention previously shown to be efficacious in improving children's physical activity, fundamental movement skills and cardiorespiratory fitness. The 'Internet-based Professional Learning to help teachers support Activity in Youth' (iPLAY) study will focus largely on online delivery to enhance translational capacity.

METHODS/DESIGN: The intervention will be implemented at school and teacher levels, and will include six components: (i) quality physical education and school sport, (ii) classroom movement breaks, (iii) physically active homework, (iv) active playgrounds, (v) community physical activity links and (vi) parent/caregiver engagement. Experienced physical education teachers will deliver professional learning workshops and follow-up, individualized mentoring to primary teachers (i.e., Kindergarten - Year 6). These activities will be supported by online learning and resources. Teachers will then deliver the iPLAY intervention components in their schools. We will evaluate iPLAY in two complementary studies in primary schools across New South Wales (NSW), Australia. A cluster randomized controlled trial (RCT), involving a representative sample of 20 schools within NSW (1:1 allocation at the school level to intervention and attention control conditions), will assess effectiveness and cost-effectiveness at 12 and 24 months. Students' cardiorespiratory fitness will be the primary outcome in this trial. Key secondary outcomes will include students' moderate-to-vigorous physical activity (via accelerometers), fundamental movement skill proficiency, enjoyment of physical education and sport, cognitive control, performance on standardized tests of numeracy and literacy, and cost-effectiveness. A scale-up implementation study guided by the RE-AIM framework will evaluate the reach, effectiveness, adoption, implementation, and maintenance of the intervention when delivered in 160 primary schools in urban and regional areas of NSW.

DISCUSSION: This project will provide the evidence and a framework for government to guide physical activity promotion throughout NSW primary schools and a potential model for adoption in other states and countries.

Young children from around the world are accessing the internet in ever increasing numbers. The rapid increase in internet activity by children aged 4–5 years in particular is due to the ease access enabled them by touchscreen internet-enabled tablet technologies. With young children now online, often independently of adult supervision, the need for early childhood cyber-safety education is becoming urgent. In this paper, we report the early findings from a project aimed at examining the development of cybersafety education for young children. We argue that cyber-safety education for young children cannot be effectively developed without first considering young children’s thinking about the internet. In this paper, we use Vygotsky’s ideas about the development of mature concepts from the merging of everyday and scientific concepts. We identify the potential range of everyday concepts likely to form the basis of young children’s thinking about the internet as a platform for cyber-safety education in the early years.

This study explores the notion of plagiarism and the Internet from 11 English as Second Language (ESL) teachers and 186 first-year ESL students at South-Coast University in Melbourne, Australia. Data collection was by a questionnaire and semi-structured interviews, and coded using SPSS and N*Vivo software to ascertain trends in response. The most significant difference in response related to the concept of the Internet as copyrightable space. ESL teachers in this study regarded cyberspace as a limitless environment for ‘cut and paste’ plagiarism in students’ academic writing, whereas ESL students considered the Internet a ‘free zone’ and not governed by legal proprietary rights. These conflicting views, it is suggested, relate to differing notions of authorship and attribution: the Romantic notion protected by legal theory and sanctions versus literary theory and techno-literacy notions of authorship. This research highlights the need to reformulate plagiarism policies in light of global and technological perspectives of authorship and attribution of text.

This paper reports key findings from an interpretive study of Australian banking consumer experiences with the adoption of internet banking. The paper provides an understanding of how and why specific factors affect the consumer decision whether or not to bank on the internet, in the Australian context. A theoretical framework is provided that conceptualizes and links consumer-oriented issues influencing adoption of internet banking. The paper also provides a set of recommendations for Australian banks. Specifically, the findings suggest that convenience is the main motivator for consumers to bank on the internet, while there is a range of other influential factors that may be modulated by banks. The findings also highlight increasing risk acceptance by consumers in regard to internet-based services and the growing importance of offering deep levels of consumer support for such services. Gender differences are also highlighted. Finally, the paper suggests that banks will be better able to manage consumer experiences with moving to internet banking if they understand that such experiences involve a process of adjustment and learning over time, and not merely the adoption of a new technology.

This paper presents findings from an empirical study of banking customer experiences with the adoption of Internet banking. Using a qualitative, interpretive grounded theory approach and single and group interviews, the study explores customer perceptions and experiences and provides an understanding of how and why specific factors affect their decision whether or not to bank on the Internet in the current era. The findings are used to develop a theoretical framework which conceptualizes and links consumer issues influencing the adoption of this application, and we also provide a set of recommendations for banks. Specifically, the findings suggest that convenience – in particular, time savings – is the major motivator to bank on the Internet, while there are a range of other influential factors which could be modulated by banks. The results also highlight increasing online risk acceptance by customers and the growing importance of deep levels of customer support for online services. Key gender differences in attitudes to Internet banking are highlighted. This study suggests that organizations will improve their management of customer attitudes to new Internet service applications by understanding the need to proactively address customer fears and misconceptions about the technologies involved.

ISSUE ADDRESSED: To explore the feasibility of using the Internet and e-mail to promote physical activity in a defined community.

METHODS: An online survey was conducted through a community-based Internet Service Provider (ISP). ISP clients were recruited via electronic newsletter and direct e-mail. Data were collected on preferred sources of assistance for physical activity advice and stage of motivational readiness for physical activity.

RESULTS: Valid surveys were completed by 797 (9% response rate). Participants were: 55% men; 56% aged >45 years; 57% worked full time; mean BMI was 28+/-8. Thirty-six per cent were in the early stages of motivational readiness for physical activity. More than 70% were somewhat to extremely interested in having access to a physical activity website.

CONCLUSION: Promoting physical activity via the Internet and e-mail is feasible and appealing to some people. Expanding the reach, appeal and use of this technology to deliver physical activity programs will be a challenge.

Introduction.There has been limited evaluation of the effectiveness of psychological interventions for female sexual dysfunction (FSD). Furthermore, none of these studies have evaluated the effectiveness of these programs delivered over the Internet.

Aim.The current study evaluated an Internet-based psychological treatment program for FSD. Revive consisted of three well-established and validated treatment components: communication skills training, sensate focus exercises, and regular contact with a therapist.

Main Outcome Measures.  Outcome measures included: the Female Sexual Function Index; the Depression, Anxiety, Stress Scale; the Sexual Function Scale; and the Personal Assessment of Intimacy in Relationships.

Methods.  In total, 39 women (17 in treatment group and 22 in control group) completed the program. The mean age for the treatment group was 34.91 (standard deviation [SD] = 10.27) and 33.30 years (SD = 9.34) for the control group.

Results.The results demonstrated that women who completed treatment reported improved sexual and relationship functioning in comparison with those who received no treatment.

Conclusions.These findings highlight the suitability of the Internet for providing psychological treatment for FSD and for targeting the individual and relationship factors often associated with these disorders.

This article presents the findings from a survey of Australian Internet users (n = 1172), conducted in 2007, investigating their overall experience of connectivity at home. Experience of connectivity is defined to mean how people use the Internet to achieve general outcomes of value to them in their everyday lives, and includes both the range of outcomes and the significance of the Internet in achieving them. The survey, thus, reports on the experience of a single behaviour – ‘using the Internet’ – rather than, as common in other research, multiple specific behaviours conducted while online. The article analyses the data collected to draw conclusions that provide greater depth of understanding of connectivity understood as the phenomenon in, and of, itself. This article contributes important information about the experiences of Australian Internet users, about which there have been only a few and relatively superficial studies. It also provides an example of a new approach to surveying Internet users that can lead to more direct conclusions about the value and extent of their uses of connectivity in their lives.
