A further study to investigate the detection and enhancement of latent fingerprints using visible absorption and luminescence chemical imaging

This study investigated the application of chemical imaging to the detection of latent fingerprints using the Condor macroscopic chemical imaging system (ChemImage Corp., Pittsburgh, USA). Methods were developed and optimised for the visualisation of untreated latent fingerprints and fingerprints processed with DFO, ninhydrin, cyanoacrylate, and cyanoacrylate plus rhodamine 6G stain. The results obtained with chemical imaging were compared to the detection achieved using conventional imaging techniques. The Condor significantly improved the detection of many prints, especially those that might be considered poor quality or borderline prints. Prints on newspaper treated with ninhydrin and DFO, and prints on white and yellow paper treated with ninhydrin, benefited the most from chemical imaging detection. In many cases, fingerprints undetectable using conventional imaging techniques could be visualised with chemical imaging. Ridge detail from untreated prints on yellow paper was also detected using the Condor. When prints of high quality were examined, both detection techniques produced quality results. The results of this project demonstrate that chemical imaging offers advantages over conventional visualisation techniques when examining latent fingerprints, especially those that would be considered difficult, such as weak prints or prints on surfaces that produce highly luminescent backgrounds. Standard testing procedures for the detection and enhancement of fingerprints by chemical imaging are presented and discussed.     

Sudden death related to small coronary artery disease

Two cases of sudden death of young people in apparently good health are reported. The only pathologic change found was a fibromuscular dysplasia of the artery supplying the conduction system of the heart with an important narrowing of the lumen and strong thickening of the arterial wall. The first case was of a 12-year-old girl who died suddenly while skiing; the second was of a 32-year-old man who died while talking to his wife. No other pathologic changes were found at autopsy, and the results of toxicologic analysis were negative. There was no individual or family history of cardiac diseases. These cases illustrate the importance of an analysis of the conduction system, including examination of the intramural coronary arteries supplying the conduction system.     

A Tale of Two Councils. Explaining the Weakness of the SVP in the Upper House of the Federal Parliament

The SVP is the strongest party in the National Council, but the weakest among governmental parties in the Council of States. This article analyses possible explanations for this surprising difference by combining macro‐level information on electoral results and data from recent election studies. The results presented show that the weakness of the SVP in the Council of States is due neither to its decision to compete only in selected constituencies, nor to “mechanical” effects of the electoral system. Rather, this weakness is explained both by the strategic behaviour of voters, who avoid “wasting” their vote in the majoritarian election of the Council of States, and by incumbency effects. The SVP is further disadvantaged by its ideological position, as its candidates have more difficulty gathering the majority of votes required for election in the Council of States than do, for instance, those of the centre‐right parties.     

Forensic Analysis Reveals Acute Decompensation of Chronic Heart Failure in a 3500‐Year‐Old Egyptian Dignitary

Naturally preserved and embalmed bodies from archeological contexts represent a powerful source of information for forensic investigators. They allow one to ascertain pathology, cause of death, to enhance diagnostic methodology, and to improve the analysis of altered remains. We investigated the complete head and lung remnants of a 3,500‐year‐old Egyptian dignitary by radiological, microscopic, and genetic approaches. The individual, a middle‐aged male, suffered from severe periodontitis, mild atherosclerosis, and experienced cardiogenic pulmonary insufficiency with recurrent mini‐bleeds and pulmonary edema. Histology and ancient DNA analyses excluded the presence of Mycobacterium tuberculosis or of any other pathogenic species. Based on our collection of evidence, we propose that acute decompensation complicating chronic cardiac insufficiency was the likely cause of death. The underlying causes for this failure remain unknown although chronic hypertension appears to be the most likely candidate. Our finding represents the earliest reported case of chronic heart failure in ancient mummies.     

Developing Management Practices to Support Joined‐Up Governance

Various forms of ‘boundary‐crossing’ practices continue to proliferate in public management and public service provision (i.e. activities that require engagement and collaboration across sectors, institutions, and organisations). Yet the dynamic nature of this type of joined‐up working is proving to be a major management challenge. In this paper, we bring a number of concepts to bear on the management of joined‐up and cross‐boundary working in public management of complex social issues. Firstly, we present the concept of ‘adaptive management’, which we draw from field of environmental policy and planning (and human ecology). Secondly, we introduce a rethinking of the role of ‘policy targets’ using a complexity lens. These concepts are integrated into a practice heuristic (or framework) designed to assist cross‐boundary policy implementation in real‐world settings. We argue that adaptive management approaches may have significant utility for ensuring effective governance in uncertain environments.     

Measuring dynamic collaborations: Collaborative health assessment tool

The changing nature of organisations in the public sector means that collaboration has become an imperative for many. Notwithstanding considerable scholarly agreement about factors contributing to successful collaboration, a broadly accepted model of collaborative practice has not coalesced. In this paper, we put forward an augmented collaboration assessment tool. Building on existing research, we argue that systems thinking can help us better account for the dynamic and multidimensional nature of collaboration – a process in which partner organisations are interconnected and organised in a way that seeks to achieve a common purpose that they could not have achieved alone. We tested the validity of our tool using a three‐stage, iterative mixed‐methods approach. Our research confirms the value of a diagnostic tool to assist collaboration partners navigate an often uncertain terrain. It further establishes the value of our tool in illuminating a collaboration's dynamic interactions as a means to evaluate ‘collaboration health’.     

The implementation of complex social policy: Institutional layering and unintended consequences in the National Disability Insurance Scheme

In this article, we identify the unfolding unintended consequences which flow from one instance of policy layering in Australia's National Disability Insurance Scheme (NDIS). We show how use of a causal diagram, which highlights feedback loops and emergent properties, to map complex chains of causal factors can assist policy scholars and policy practitioners to understand the likely direction of change and possible responses. In the case of Australia's National Disability Insurance Scheme, our analysis suggests that the likely direction of change will work against two of the fundamental design features of the NDIS: providing participants with more choice and control, and ensuring all eligible Australians are able to access appropriate services and supports regardless of where they live. Our analysis points to the use of price regulation as the site of potential intervention because of the role it plays in subsequent feedback loops and the development of the two, unwelcome, emergent properties.
