Conceptualizing the Landscape of Decision Making for Complex Problem Solving

Complex problem resolution often involves the need for a pragmatic integration of knowledge from stakeholders with competing epistemic claims. The decision-making process regarding complex problem resolution is characterized by four basic sources of knowledge: disciplines, societies, organizations, and individuals. From the perspective of the public administration, we conceptualize the structure of the interactions between the disciplines and other sources of knowledge potentially relevant to the resolution of a public problem. To aid this exercise we examine a series of cases that we believe represent relevant aspects of complex problem resolution. We describe these basic interactions as collaborative, agnostic, or adversarial. This is a reorientation to the knowledge at play in the problem at hand. The study of public administration is well suited as a body of knowledge to address complex problems because it has a rich history of cooperation with other disciplines, practitioners, and stakeholders in the public.     

Methods for the analysis of hard dental tissues exposed to high temperatures

The preservation of teeth that have been exposed to a heat source is a key factor in order to keep their value as evidence. This research paper presents some methods under development for the analysis of dental evidence after exposure to high temperatures; it also establishes age related alterations of young and aged teeth which have been exposed to direct heat. A total of thirty permanent healthy teeth (young=15 and old=15) were submitted to direct heat (n=14) and to a controlled raise of temperature (n=16); they were embedded in polymethylmetacrilate. For the macroscopic study, blocks were cut in half, polished and their surfaces were digitalized. Subsequently, blocks were put in slides, worn away and observed through a photomicroscope. The study of the colorimetric pattern was done by Corel Photo Paint 12.0 and Image J. software. All teeth submitted to the gradual raise of temperature presented a degree of structural damage lower than those exposed to direct heat. The internal surface of young teeth exposed to direct heat showed lines of fracture oblique to the long axis of the tooth; in contrast, a reticular pattern was observed on aged teeth. All teeth exposed to direct heat showed some matte-black coloration areas, while those submitted to a gradual increment of temperature showed a greyish colour in the enamel and a chalky-white in the cementum. By using both thermal treatments in young teeth, the amelodentinal junction was lost, thus preserving the integrity of each tissue. In aged teeth, the separation of this junction was produced because of the breakdown of the dentine. Microscopically, in teeth exposed to direct heat, it was neither possible to differentiate the dentin from the cementum, nor to distinguish the incremental lines of the latter; while in those submitted to a controlled increment of temperature, the corresponding morphology in the tissues was observed. A significant statistical difference was obtained for black colour among young and aged teeth exposed to direct heat, as well as among the means of all colours obtained from the teeth exposed to both treatments. The structural changes observed allow locating a tooth in the studied age groups. Our results show the viability of the applied method for the processing of samples, allowing their preservation as evidence during an indefinite time.     

Grounding transnational business governance: A political-strategic perspective on government responses in the Global South

Recent scholarship on transnational business governance has begun to examine public-private interactions and the active role of governments. We make two key contributions that integrate and expand this literature. First, in juxtaposition to functionalist accounts, we foreground the fundamentally political and often contentious character of these interactions. As private transnational governance schemes and standards “hit the ground,” private-public interactions, we argue, are embedded in national political arenas and tied to domestic distributional struggles among competing regulatory coalitions. Building upon multiple empirical streams of research, we develop a political-strategic framework that maps the diversity of Southern government responses (substitute, adopt, repurpose, replace, or reject) to transnational private governance. Our framework shows that government responses are a function of both strategic fit with domestic industrial capabilities and structures, and strength of developmental state capacity. Second, our proposed framework adopts the vantage point of Global South governments and industries, particularly how development challenges and strategic options within global value chains affect their understanding of, and responses to, transnational schemes and standards. This is an important corrective to a Northern bias in the private governance literature.     

Do intergovernmental transfers affect the distribution of manufacturing production across regions in federal countries? Theory and evidence for Argentina

The effect of changes in the distribution of top-to-bottom intergovernmental transfers on the location of manufacturing production is analysed using a modified version of the footloose capital model. An increase in the share of transfers received by a region increases its share of manufacturing production the larger are transaction costs; the larger is the share of transfers going directly to consumers; the larger is the share of manufacturing consumption vis-à-vis non-tradable consumption; and the easier consumers can substitute among manufacturing varieties. Using data for Argentina for 1983-2005, the empirical analysis appears to support the existence of two distinctive regimes, with smaller/poorer provinces benefiting in terms of the location of manufacturing production as a response to an increase in transfers. Also, for these provinces, the benefits are greater if they are politically aligned with the federal government, especially through the receipt of discretionary transfers. For large/rich provinces, the evidence is less conclusive.     

Shells and Bones: A Forensic Medicine Study of the Association of Terrestrial Snail Allopeas micra with Buried Human Remains in Brazil

Little is known regarding the scavenger fauna associated with buried human corpses, particularly in clandestine burials. We report the presence of 20 shells of the terrestrial snail Allopeas micra, within hollow bones of human remains buried for 5 years, during the process of collecting DNA material. The fact that a large number of shells of A. micra had been found in the corpse and in the crime scene supports the assumption that there was no attempt to remove the corpse from the area where the crime occurred. Despite this, our observations cannot be used to estimate the postmortem interval because there is no precise knowledge about the development of this species. This is the first record of a terrestrial snail associated with a human corpse and its role in this forensic medicine case.
