Forensic identification of students outsourcing assignment projects from freelancer.com

This paper reports the increasing popularity of outsourcing academic works by university students motivated by the lure of lucrative dividends and visa opportunities. Due to a lack of formal methods in detecting such transactions, freelance websites are thriving in facilitating the trade of outsourced assignments. This is compounded by the fact that many university staff have neither the time nor training to perform complex media analysis and forensic investigations. This paper proposes a method to aid in the identification of those who outsource assignment works on the most popular site freelancer.com. We include a recent real-world case study to demonstrate the relevancy and applicability of our methodology. In this case study, a suspect attempts to evade detection via use of anti-forensics which demonstrates the capability and awareness of evasion techniques used by students.

Location privacy preserving for semantic-aware applications

With the increase use of location-based services, location privacy has recently raised serious concerns. To protect a user from being identified, a cloaked spatial region that contains other k-1 nearest neighbors of the user is used to replace the accurate position. In this paper, we consider location-aware applications that services are different among regions. To search nearest neighbors, we define a novel distance measurement that combines the semantic distance and the Euclidean distance to address the privacy preserving issue in the above-mentioned applications. We also propose an algorithm kNNH to implement our proposed method. The experimental results further suggest that the proposed distance metric and the algorithm can successfully retain the utility of the location services while preserving users’ privacy.

A model driven approach to care planning systems for consumer engagement in chronic disease management

This work demonstrates a model-driven approach to the development of care plan systems, amenable to: (a) a flexible and extensible definition of care plan scope; and (b) deployment of care plan viewing and tracking functionality to a wide range of physical computing devices. The approach utilises a care plan domain model from which guideline implementers formulate care plan templates aligning to specific clinical guidelines. A clinical end user would subsequently constrain that template (e.g., selecting a subset of available activities and specific targets) to create a care plan instance for an individual patient. An XML care plan visualisation definition created using the Marama tool is transformed to OpenLaszlo script from which Shockwave Flash objects can be compiled, creating Flash applications that run on a variety of hardware for both clinical and patient users. The approach is illustrated with respect to an overweight and obesity guideline.

Small-scale rural pilot programs in chronic illness management - what next?

In recent years, rural SA has been the recipient of significant funding to support a range of new primary health care initiatives. Much of this funding, additional to normal recurrent budgets in our health system, has facilitated effective change and development through demonstration and research projects across the state. The resultant work involves programs such as: ? coordinated care trials (COAG) ? more allied health services (MAHS) ? Commonwealth regional health service initiatives (CRHS) ? quality use of medicines (QUM) ? community packages for aged care services ? Indigenous chronic disease self-management pilot programs (CDSM) ? chronic disease self-management (CDSM) programs - Sharing Health Care SA ? chronic disease self-management (CDSM) programs in Indigenous communities. In addition to the resources listed above, funding was also provided by the Commonwealth to establish the South Australian Centre for Rural and Remote Health (SACRRH) and develop the University Department of Rural Health in Whyalla. While this new funding has led to substantial developmental work in chronic illness management in particular, one needs to ask whether the time might not be right now for these hitherto small-scale change initiatives to be transformed into ongoing mainstream programs, informed and guided by research outcomes to date. Is it time to move beyond tentative chronic illness programs and into mainstream reform? We have shown that there is much to be gained, both for patients and for the system, from improved coordination of primary care services and initiatives such as self-management programs for patients with chronic conditions. Better management leads to improved patient health outcomes and can reduce demand for unplanned hospital and emergency services. Many admissions to rural hospitals requiring expensive services, in terms of infrastructure and staffing, could be either prevented, or patients could be managed more effectively in the community as part of a wider primary health care program.

ID scanners and überveillance in the night-time economy: crime prevention or invasion of privacy?

ID scanners are promoted as an effective solution to the problems of anti-social behavior and violence in many urban nighttime economies. However, the acceptance of this and other forms of computerized surveillance to prevent crime and anti-social behavior is based on several unproven assumptions. After outlining what ID scanners are and how they are becoming a normalized precondition of entry into one Australian nighttime economy, this chapter demonstrates how technology is commonly viewed as the key to preventing crime despite recognition of various problems associated with its adoption. The implications of technological determinism amongst policy makers, police, and crime prevention theories are then critically assessed in light of several issues that key informants talking about the value of ID scanners fail to mention when applauding their success. Notably, the broad, ill-defined, and confused notion of "privacy" is analyzed as a questionable legal remedy for the growing problems of überveillance.
