Media analyses based on Microsoft NTFS file ownership

The ever-increasing size of digital media presents a continuous challenge to digital investigators who must rapidly assess computer media to find and identify evidence. To meet this challenge, methods must continuously be sought to expedite the examination process. This paper investigates using the file ownership property as an analytical tool focusing on activity by individuals associated with the computer. Research centered on the New Technology File System (NTFS), which is the default file system in Microsoft Windows Operating System (OS). This was done because Microsoft's worldwide market penetration makes Windows and NTFS the most likely OS and file system to be encountered in digital forensic examinations. Significantly, digital forensic software now allows examination of NTFS file attributes and properties including the ownership property. The paper outlines potential limitations regarding interpreting ownership findings, and suggests areas for further research. Overall, file ownership is seen as a potentially viable new digital forensic tool.     

EARLY INTERVENTION IN NEW ZEALAND FAMILY COURT CASES

In April 2010 the New Zealand Family Court introduced the National Early Intervention Process (NEIP) to diversify its previous unitary dispute resolution pathway into two tracks (standard and urgent). A “triage” model is now in use to assess and assign cases appropriately. This article outlines the key milestones in the Family Court's 30‐year history which have led to this new initiative to reduce delays and help avoid the escalation of family conflicts over the care of children into bitter and intractable disputes. NEIP represents the most overarching reform of the Family Court since the Court's inception in 1981.     

Ventilatory and metabolic demands during aggressive physical restraint in healthy adults

We investigated ventilatory and metabolic demands in healthy adults when placed in the prone maximal restraint position (PMRP), i.e., hogtie restraint. Maximal voluntary ventilation (MVV) was measured in seated subjects (n=30), in the PMRP, and when prone with up to 90.1 or 102.3 kg of weight on the back. MVV with the heaviest weight was 70% of the seated MVV (122+/-28 and 156+/-38 L/min, respectively; p<0.001). Also, subjects (n=27) were placed in the PMRP and struggled vigorously for 60 sec. During the restrained struggle, ventilatory function (V(E)/ MVV) was 44% of MVV in the resting PMRP. While prone with up to 90.1 or 102.3 kg on the back, the decrease in MVV was of no clinical importance in these subjects. Also, while maximally struggling in the PMRP, V(E) was still adequate to supply the ventilatory needs.
