Optimisation and evaluation of 1,2-indanedione for use as a fingermark reagent and its application to real samples

1,2-indanedione is an emerging fingermark reagent used on porous surfaces. The general consensus is that this reagent is at least as sensitive as DFO, with some research showing higher sensitivity for 1,2-indanedione as opposed to DFO. However, a number of discrepancies existed in the literature as to which formulation and which development procedure produces optimal results. This project set out to investigate the best formulation and development procedure under Australian conditions, encompassing all published recommendations as well as some novel approaches. 1,2-indanedione formulations were compared with respect to initial colour, fluorescence, concentration of reagent, acetic acid concentration, and the effect of different carrier solvents. Numerous development conditions were investigated, including a conventional oven, a heat press and humidity. Further enhancement using metal salt treatment and liquid nitrogen was also evaluated. The heat press set at 165 degrees C for 10s proved to give the best initial colour and most intense luminescence. Secondary metal salt treatment improved initial colour and luminescence. The Polilight, the VSC 2000, and the Condor Chemical Imaging macroscope have been used to detect the fingerprints developed with 1,2-indanedione on a variety of high- and low-quality porous and semi-porous surfaces, with impressive results overall. Laboratory and field tests were conducted to compare 1,2-indanedione with DFO and ninhydrin as well as to investigate the position of 1,2-indanedione in the sequence of reagents for fingermark detection on porous surfaces. Overall, 1,2-indanedione proved to be a viable alternative to traditional methods for the detection of fingermarks on porous surfaces, with more fingermarks being developed using this reagent on real samples than both DFO and ninhydrin and a combination of the two reagents.     

The US Supreme Court Affirms the Filartiga Paradigm

In 2004, for the first time in history, the United States SupremeCourt addressed the meaning and scope of the Alien Tort Statute(ATS) of 1789. Originally intended to provide redress for actsof piracy or offences against ambassadors, the Statute has beenused since the 1980 watershed case of Filartiga v. Peña-Iralato award damages in civil trials in the United States to foreignvictims of, inter alia, torture, summary execution and forceddisappearance. Opponents have claimed, among other things, thatuse of the ATS shows disregard for principles of internationalcomity; is inconsistent with principles governing the use ofuniversal jurisdiction; and results in an imperialist Americanprivatization of human rights. The author argues that the SupremeCourt's decision in Sosa v. Alvarez-Machain limits the ATS toa tool of complementary justice consistent with prevailing principlesof global accountability.     

The population of coloured textile fibres in domestic washing machines.

A population survey was carried out to analyse examples of the coloured fibre population that may be expected to exist in both front- and top-loading domestic washing machines during Spring, in Sydney, Australia. White cotton T-shirts were washed both individually, and with a normal household wash load, then taped to recover extraneous fibres transferred during the wash cycle. Twelve thousand one hundred and seventy-eight fibres were classified according to length, colour and generic class. Cotton fibres were most prevalent (69.4%), followed by man-made fibres (24.2%). The most common colour/generic class combinations were black/grey cotton (27%), blue cotton (20%) and red cotton (15.6%). Other combinations generally represented under 2% of the total fibre population. Two thirds (65.9%) of the recovered fibres were under 2 mm in length, the proportion of fibres decreasing with increasing fibre length. Variations in machine type did not affect the distribution of fibres with respect to fibre type, colour or length.     

Engaging elite support for the poorest? BRAC's Targeted Ultra Poor programme for rural women in Bangladesh

This article draws preliminary lessons from the experience of engaging village elites in support of a BRAC programme for ultra-poor women in rural Bangladesh. It describes the origins, aims, and operation of this programme, which provides comprehensive livelihood support and productive assets to the extreme poor. Based on field research in the rural north-west, the article examines the conditions under which elites can support interventions for the ultra-poor, and the risks and benefits of such engagement. It describes the impact of committees mandated to support ultra-poor programme participants, and attempts to understand the somewhat paradoxical success of this intervention. Conclusions and lessons from the experience involve revisiting assumptions that dominate scholarship and programmes relating to the politics of poverty in rural Bangladesh.     

Let's Get Public Administration Right,But in What Sequence?: Lessons from Japan and Singapore

The so‐called Good Governance Model requires perfect public administration that is accountable, efficient, equitable, representative, responsive and transparent and that respects the rule of law. Accordingly, the Good Governance Movement promotes a variety of public administration reforms worldwide. However, the effectiveness of promoting all kinds of administrative reforms at once is in question, because that could overwhelm the reform capability of countries, and more important, some reforms can compete with, rather than complement, one another. Such scenarios are possible, and the implication is clear: administrative reform discourse must consider how to best sequence and prioritize reforms, the outcomes of which must be identified. The experiences of Japan and Singapore offer some insight into this. This study first codifies administrative reforms by using the concepts of administrative themes, and it systematically traces, compares and contrasts reforms in both countries in light of these themes. This leads to the conclusion that the sequences in which administrative reforms evolved in those places contributed to dissimilarities in their administrative traditions today.

The Roads to Transformation: Budgeting Issues in the Czech and Slovak Federal Republic 1989–1992

The Czech and Slovak Federal Republic no longer exists, but by the time of its dissolution, the transformation from a socialist to a democratic model of budgeting to another was well under way. This article illustrates some of the major issues facing countries attempting to remodel their systems of budgeting and financial management toward a more liberalized and democratic society.     

Vacuum metal deposition: factors affecting normal and reverse development of latent fingerprints on polyethylene substrates

Vacuum metal deposition (VMD) is an established technique for the development of latent fingerprints on non-porous surfaces. VMD has advantages over cyanoacrylate fuming, especially in circumstances where prints are old, have been exposed to adverse environmental conditions, or are present on semi-porous surfaces. Under normal circumstances, VMD produces 'negative' prints as zinc deposits onto the background substrate and not the print ridges themselves. A phenomenon of 'reverse' development, when zinc deposits onto the print ridges and not the background, has been reported by many authors but its causes have not been conclusively identified.Four plastic substrates were used in this study and these could be easily divided into two groups based on the types of development observed as the amount of deposited gold was increased. On group I plastics, identified as low-density polyethylene (LDPE), normal development then reverse development and finally no development resulted with increasing gold. On group II plastics, identified as high-density polyethylene (HDPE), normal development then over-development and finally poor-quality normal development resulted with increasing gold. Our results suggest that the difference between these plastic types causes variations in the gold film structure which in turn dictates the nature of the zinc deposition.On group I plastics, the structure and thickness of the gold film has been identified as the critical factor in the occurrence of normal or reverse development. Thin gold films on plastic substrates form small 'clusters' (or agglomerates) rather than the atoms being uniformly spread over the surface. The size and shape of these clusters is critical. Once the clusters reach a certain morphology, they no longer act as nucleation sites for zinc, and hence, zinc will not deposit onto the substrate.On group II plastics, results suggest that the gold clusters are smaller and more densely packed. Hence, even though the same amount of gold has been deposited, the gold clusters in this case do not reach the critical morphology and so continue to act as nucleation sites for zinc.Typically, zinc will not deposit onto the fingerprint ridges as the gold nucleation sites are buried within the print residue. However, when more gold is deposited, gold emerges at the surface of the latent print allowing zinc deposition onto the ridges.The rate of gold evaporation was found not to affect the structure of the gold film, although a slower rate of evaporation resulted in more effective deposition.
