Doped hydrophobic silica nano- and micro-particles as novel agents for developing latent fingerprints

Novel hydrophobic silica based particles have been developed to visualise latent fingerprints. The composition of the particles has been designed to maximise both hydrophobic and ionic interactions between a variety of coloured and fluorescent reporter molecules and the silicate backbone within the particles. The resulting doped particles retain the incorporated dyes with high affinity. In addition, a variety of sub-particles have also been embedded to again produce coloured or magnetisable hydrophobic particles. The particles can be harvested as nanoparticles or microparticles. The former are applied to latent fingerprints as an aqueous suspension and the latter as a dusting agent using brushes or a magnetic wand. Examples of the prints produced using these agents are given. The resulting prints have good definition.     

Understanding Pathways to Family Dispute Resolution and Justice Reforms: Ontario Court File Analysis & Survey of Professionals

This article reports on two related studies about varying pathways to the resolution of family disputes and the effects of family justice reforms in Ontario: a survey of family court professionals (n = 118) and an analysis of 1,000 closed court files of family cases involving children. Both studies reveal that the vast majority of cases are resolved without a trial, often by negotiation. While professionals generally support family justice reform initiatives, there remain significant gaps in the implementation of these strategies. For example, many litigants do not attend information programs despite the requirement for mandatory attendance; there is limited use of mediation; the views of children are being sought in only a small number of cases; and there is a large proportion of self‐represented family litigants. Despite the increase in shared care and joint decision‐making arrangements, a majority of cases in the court file study were sole custody arrangements to the mother, whether the case was settled or resolved by trial. Mediation was associated with greater time of contact with the non–primary residential parent (usually the father).
