Smartphones are mobile phones that offer processing power and features like personal computers (PC) with the aim of improving user productivity as they allow users to access and manipulate data over networks and Internet, through various mobile applications. However, with such anywhere and anytime functionality, new security threats and risks of sensitive and personal data are envisaged to evolve. With the emergence of open mobile platforms that enable mobile users to install applications on their own, it opens up new avenues for propagating malware among various mobile users very quickly. In particular, they become crossover targets of PC malware through the synchronization function between smartphones and computers. Literature lacks detailed analysis of smartphones malware and synchronization vulnerabilities. This paper addresses these gaps in literature, by first identifying the similarities and differences between smartphone malware and PC malware, and then by investigating how hackers exploit synchronization vulnerabilities to launch their attacks.

Purpose – The purpose of this paper is to review the development of the empirical literature on international outsourcing of information technology services (ITS) over the 1992-2007 period and to identify future research areas.

Design/methodology/approach – A sample of 78 empirical academic publications on international outsourcing of ITS conducted between 1992 and 2007 across 46 scholarly journals constitutes the main data for analytical purposes. The sample is compiled following extensive electronic searches of the main academic databases. After clustering the studies in the sample according to their main research areas, a narrative approach is used to review developments in each cluster and to identify emerging research areas.

Findings – Four main areas of research are identified, namely outsourcing decision, outsourcing management (OSM), outsourcing outcome and the role of offshore service providers (OSPs). The review suggests that research efforts to date have been predominantly on outsourcing decision and OSM, mostly from the perspective of clients. Future research opportunities exist in the areas of outsourcing strategy and performance, the behaviour and performance of OSPs particularly within the context of firms from less-developed countries competing globally, and the nature of competition among OSPs both within and among countries.

Originality/value –
This is the first review which focuses on empirical studies of outsourcing for ITS. This paper identifies several gaps in the literature and points to the need for more research on outsourcing from the perspective of OSPs.

The use of manualized treatment programs offers a useful research framework for assessing psychotherapeutic interventions for female sexual dysfunctions (FSDs), but it does not address all issues related to methodological rigor and replication, and raises new research issues in need of discussion. Aims. The goals of this manuscript are to review the literature on treatment trials utilizing manualized psychotherapy treatments for FSD and to explore the benefits and research issues associated with the flexible use of treatment manuals. Methods. The method used was the review of the relevant literature. Results. While the use of manualized treatments for FSDs can address certain methodological issues inherent in psychotherapy research, flexibility in manual administration is necessary in order to allow tailoring for individual needs that can be beneficial to both the participant and the research. The flexible use of manuals, as opposed to strict manual adherence, may also be more relevant for clinical utility. Conclusions. In order to administer manualized treatments for FSDs with appropriate flexibility, while also maximizing internal validity and replicability, the authors recommend that predetermined decision rules be utilized to guide individual tailoring, that potential gaps in the manual be identified and addressed, and that differing levels of motivation and readiness for treatment be taken into consideration in the treatment protocol.

Purpose – The purpose of this paper is to explore the understanding of the term corporate social responsibility (CSR) by Sri Lankan immigrant entrepreneurs in Australia. It also seeks to investigate the importance the entrepreneurs place on CSR, their understanding of stakeholders, the types of CSR activities undertaken by them, and the issue of social capital.

Design/methodology/approach –
Data were collected through in-depth semi-structured interviews with Sri Lankan entrepreneurs based in Victoria, Australia.

Findings – The interviewees were aware of the term CSR but, nevertheless, had different interpretations of its meaning. However, CSR was considered important and all the interviewees were, in some way, involved in CSR activities and also had a good understanding of the importance of their stakeholders. Findings also highlighted the significance attached to social capital by the entrepreneurs such as informal relationships and trustworthiness which build the intangible attributes of CSR. The present findings can be attributed to immigrant entrepreneurs behaving partly to adapt to the host country, by changing their beliefs, values, traditions and partly by being influenced by their home country culture as found in the extended part of this current study.

Research limitations/implications –
This paper addresses gaps in the fields of both CSR and immigrant entrepreneurship literature. However, the small sample size is a limitation and further research is required in order to generalize the findings.

Originality/value –
It is important to have an understanding of the interpretation of social responsibility amongst immigrant entrepreneurs. Despite the steadily growing number of Sri Lankan immigrant entrepreneurs and their potential impact on the Victorian and Australian socio-economic context, this area remains under-researched. This paper addresses this gap in the literature and makes an attempt to provide insight into this area that can be used as a catalyst for future research.

For more than 25 years, universities have been acknowledged as having the potential to make crucial contributions to addressing the challenges of environmental sustainability. During this time, many universities have undertaken activities in support of sustainability, although few have succeeded in realizing their potential to make significant contributions in research and education or as adopters of sustainable practices within their institutions.

This paper aims to assist universities to improve their contributions to the challenges of environmental sustainability by: reviewing current literature guiding universities to support sustainability; identifying gaps in the literature; and, proposing a composite framework to facilitate contributions by IS-enabled innovations that significantly improve the level of sustainability behaviours and practices in universities. An IS research agenda integrated with the Composite Framework is proposed.

The Nurse Practitioner – Mental Health model investigates the options for providing a service to a group of clients who present at Werribee and Western Emergency Departments (ED) and currently receive either limited mental health service or have an undiagnosed mental illness. This group comprises at risk young adults who do not meet the criteria for ongoing treatment in public mental health services at present. At risk young adults are those who fit known demographic variables for risk and have a risk catalyst (eg relationship break up) and a situational response to this (self harm). Mercy Mental Health Program service survey indicates gaps in services to this group using current referral pathway with potentially 40-70% lost to follow-up and a significant increase in risk for suicide.

Background: This review examines the associations between low vitamin B12 levels, neurodegenerative disease, and cognitive impairment. The potential impact of comorbidities and medications associated with vitamin B12 derangements were also investigated. In addition, we reviewed the evidence as to whether vitamin B12 therapy is efficacious for cognitive impairment and dementia.

Methods: A systematic literature search identified 43 studies investigating the association of vitamin B12 and cognitive impairment or dementia. Seventeen studies reported on the efficacy of vitamin B12 therapy for these conditions.

Results: Vitamin B12 levels in the subclinical low-normal range (<250 ρmol/L) are associated with Alzheimer's disease, vascular dementia, and Parkinson's disease. Vegetarianism and metformin use contribute to depressed vitamin B12 levels and may independently increase the risk for cognitive impairment. Vitamin B12 deficiency (<150 ρmol/L) is associated with cognitive impairment. Vitamin B12 supplements administered orally or parenterally at high dose (1 mg daily) were effective in correcting biochemical deficiency, but improved cognition only in patients with pre-existing vitamin B12 deficiency (serum vitamin B12 levels <150 ρmol/L or serum homocysteine levels >19.9 μmol/L).

Conclusion: Low serum vitamin B12 levels are associated with neurodegenerative disease and cognitive impairment. There is a small subset of dementias that are reversible with vitamin B12 therapy and this treatment is inexpensive and safe. Vitamin B12 therapy does not improve cognition in patients without pre-existing deficiency. There is a need for large, well-resourced clinical trials to close the gaps in our current understanding of the nature of the associations of vitamin B12 insufficiency and neurodegenerative disease.

The role of ecology in a sustainable future is prominent in the media, academic writing and political decisions; as such environmental pressures, as well as economic, social and political, increasingly influence planning for the future. This paper looks at how this translates into the process for planning future cities – highlighting gaps in knowledge and issues of implementation. It draws on interdisciplinary sources to explore three main elements of the debate: What is urban ecology and why is it important to sustainable cities?; What gaps are there in the ecological knowledge of planners and policy makers and why are there gaps?; and How can urban ecology be integrated into the planning of future sustainable cities?. This paper does not aim to provide a definitive answer to the problem; rather it addresses the first two areas and identifies potential directions for the third. It takes Australia, as national, Victoria, as regional and Geelong, as local, points of reference.

Aim:  Regular consumption of fruit and vegetables has been associated with a decreased risk of a number of chronic diseases. An appropriate level of knowledge is important to successfully adhere to the dietary guidelines for eating fruit and vegetables. However, there is little research about the level of knowledge that young adults have about fruit and vegetable consumption. The current study aimed to investigate the recall and understanding of Australian dietary guidelines, food product and serving size knowledge in a population of young adults. Methods:  One hundred and six undergraduate students completed online questionnaires regarding (1) knowledge of dietary recommendations; (2) knowledge of serving size information; and (3) foods that could be included as part of fruit and vegetable intake. Results:  The results showed that the sample had significant knowledge gaps in all three areas. Approximately half (54%) of participants correctly reported the recommended daily intake of fruit and vegetables, the majority were not able to correctly report serving sizes (correct responses were 30–61%) and were not able to identify all ingredients from a recipe that counted towards fruit and vegetable intake. Conclusions:  Past interventions have not tended to focus on the fruit and vegetable knowledge, or behaviours, of Australian young adults. On the basis of findings from this study, it appears that more work is needed to develop messages to effectively target this important group.

Cost-effective, sustainable strategies are urgently required to curb the global obesity epidemic. To date, fiscal policies such as taxes and subsidies have been driven largely by imperatives to raise revenue or increase supply, rather than to change population behaviours. This paper reviews the economic evaluation literature around the use of fiscal policies to prevent obesity. The cost-effectiveness literature is limited, and more robust economic evaluation studies are required. However, uncertainty and gaps in the effectiveness evidence base need to be addressed first: more studies are needed that collect ‘real-world’ empirical data, and larger studies with more robust designs and longer follow-up timeframes are required. Reliability of cross-price elasticity data needs to be investigated, and greater consideration given to moderators of intervention effects and the sustainability of outcomes. Economic evaluations should adopt a societal perspective, incorporate a broader spectrum of economic costs and consider other factors likely to affect the implementation of fiscal measures. The paucity of recent cost-effectiveness studies means that definitive conclusions about the value for money of fiscal policies for obesity prevention cannot yet be drawn. However, as in other public health areas such as alcohol and tobacco, early indications are that population-level fiscal policies are likely to be potentially effective and cost-saving.

The constraints that curb visitation to parks have received considerable research attention and remain an important issue. Constraints to outdoor leisure in parks include structural barriers, such as cost of entry, interpersonal barriers, for example, lack of a partner to visit with, or intrapersonal barriers, including lack of interest. Using a meta-analysis approach, this article integrates the findings of 22 North American studies with 541 estimates, conducted over a 30-year period, to determine the key constraints to park visitation based on various socio-demographic factors. The findings highlight the varying roles that constraints play in limiting the visitation of people according to race, age, gender, education and income. Gaps in the literature are identified, with implications for encouraging visitation for more constrained groups discussed. An agenda for future research is presented.

Relatively little is known about the biology and ecology of the world’s largest (heaviest) bony fish, the ocean sunfish Mola mola, despite its worldwide occurrence in temperate and tropical seas. Studies are now emerging that require many common perceptions about sunfish behaviour and ecology to be re-examined. Indeed, the long-held view that ocean sunfish are an inactive, passively drifting species seems to be entirely misplaced. Technological advances in marine telemetry are revealing distinct behavioural patterns and protracted seasonal movements. Extensive forays by ocean sunfish into the deep ocean have been documented and broad-scale surveys, together with molecular and laboratory based techniques, are addressing the connectivity and trophic role of these animals. These emerging molecular and movement studies suggest that local distinct populations may be prone to depletion through bycatch in commercial fisheries. Rising interest in ocean sunfish, highlighted by the increase in recent publications, warrants a thorough review of the biology and ecology of this species. Here we review the taxonomy, morphology, geography, diet, locomotion, vision, movements, foraging ecology, reproduction and species interactions of M. mola. We present a summary of current conservation issues and suggest methods for addressing fundamental gaps in our knowledge.

Background: Occupational light vehicles (OLV) are light passenger and loadshaped vehicles used for work. The OLV-associated injury burden is as great as that of heavy vehicle users, but has been largely ignored by occupational health and safety (OHS) regulators. Contingent employment growth has accentuated existing gaps in the policy framework between OHS and road-safety. Frequent burden shifting from OHS to road-related health systems undermines the evidence base necessary to inform policy development. Aims: To provide evidence-based recommendations for the collection of OLVuser surveillance data and to underpin OHS procedures and policies for OLVusers. Method: The literature was systematically analyzed to identify OLV-user OHS policy and practice gaps. Strategies to improve and co-ordinate surveillance systems were developed to address the identified limitations. Results: Gaps were identified in OLV-user legislation, data collection, and riskmanagement. These require strategies to improve identification of all OLV-users and to co-ordinate surveillance and OHS practice. Discussion: Contemporary reform of road and OHS, policy, provides a timely opportunity for the implementation of strategic responses to this serious road safety and occupational, public health problem.

Aims and objectives
To obtain expert consensus on essential criteria required to assess patient readiness for discharge from the postanaesthetic care unit.

Background
A patient's condition can deteriorate after surgery, and the immediate postoperative period is recognised internationally as a time of increased risk to patient safety. A recent systematic review identified evidence-based assessment criteria for the safe discharge of patients from the postanaesthetic care unit and identified gaps in the evidence.

Design
Descriptive consensus study using the Delphi method.

Methods
Members of international clinical specialist groups with expertise in anaesthesia or postanaesthetic care participated in three consultation rounds. Online surveys were used to determine expert consensus with regard to aspects of postanaesthetic care and specific criteria for assessing patient readiness for discharge. Three rounds of surveys were conducted from May 2011–September 2012.

Results
Twenty-three experts contributed to the panel. Consensus, that is, at least 75% agreement, was reached in regard to 24 criteria considered essential (e.g. respiratory rate 100%; pain 100%; heart rate 95%; temperature 91%). Consensus was also reached for 15 criteria not considered essential (e.g. appetite 96%; headache 76%). Consensus was not obtained for a further 10 criteria. Participants (95%) agreed that a discharge tool was important to ensure safe patient discharge.

Conclusion
Consensus was achieved by a panel of international experts on the use of a tool to assess patient readiness for discharge from postanaesthesia care unit and specific variables to be included or excluded from the tool. Further work is required to develop a tool and test its reliability and validity.

Relevance to clinical practice
The findings of this study have informed the development of an evidence-based tool to be piloted in a subsequent funded study of nursing assessment of patient readiness for discharge from the postanaesthetic care unit.

Research on early childhood education emphasises the importance of quality in early childhood intervention. This study examines the quality of Early Childhood Intervention Services based on parents’ experiences raising a child with developmental delay or disability. The study builds on the philosophy of Family-Centred Practice and professionals’ experiences with family-centred interventions. A qualitative case study approach was adopted to gain insight about families who are raising a child with additional needs. Nine in-depth parent-interviews and three focus groups with professionals were conducted in the first two terms of 2010. The case explicates the experiences of parents and professionals who were associated with Specialist Children’s Services in a metropolitan region of Victoria. The research concentrated on the first point of entry to early intervention, the referrals process and the waiting list. It also addressed parents' experiences, priorities and expectations. As a small-scale study, it examined parents’ and children’s needs as well as children’s access to therapy in early intervention. It also investigated community support and parent-professional relationships in the context of early childhood intervention services. The study found that family-centred intervention is beneficial to both parents and children with developmental delay or disability. However, to implement an effective family-centred approach, practitioner support in the form of professional development, supervision and peer mentorship is required to develop professionals’ reflexivity and self-efficacy in family-centred interventions. The study also identified strategies to promote effective practice, gaps in universal and specialised services, and implications for policy.
