Examining thermally induced movement of the fatal fire victim
Investigating a fatal fire scene comprises analysis not only of the fire’s development to identify the point of fire origin and ignition source, but analysis of a victim’s position and their relationship within the scene. This work presents both qualitative and quantitative results from experimentation investigating the effect of a real fire environment on the human body, and how the position of a victim at the post burn investigation stage may be significantly different to the position at fire ignition. Qualitative observations were undertaken on the burning of 39 compartment and vehicle scenes from ignition through to suppression, each containing a human cadaver. The results of analysis question the validity of previous work based on cremation observations. Quantitative results were produced by recording 13 points on the body on the X, Y and Z axis, both pre and post burn on a smaller dataset of ten compartment burns. Results have enabled a more robust assessment of thermally induced movement of the body within the scene along each axis, evidencing that pugilism is not the universal reaction of the fatal victim to thermal exposure, with extension of the upper limbs far more common than has been previously reported.
•Research on unique dataset facilitated by the burning human cadavers.•Data and analysis directly correlating to real fire scenes within both compartments, and vehicles•Research developed focusing on enhancing investigation of the fatal fire victim.•Qualitative analysis on the position of human remains both pre and post burning.•A new procedure to quantify thermally induced movement of the fatal fire victim has been established.

Applying archaeology to fire investigation techniques: A review
Archaeology and Fire Investigation do not appear to have much in common on the surface. Scratch beneath however, and the similarities begin to reveal themselves. Both disciplines require the investigation of physical remains by employing an analytical approach in order to reconstruct sequences of events. Before recovery employing an archaeological stratigraphic recording method at fire scenes, provides the opportunity for a sequential recording of both debris layers, recording objects and their relationship to the immediate environment. This approach is particularly pertinent in Fire Investigation, as the recovery of evidence can lead to destruction in cases of fragile evidence and remains.

Feminists and Queer Theorists Debate the Future of Critical Management Studies
What is CMS for and what might its future be- both inside the domain of academia and outside it? It's a question that has beguiled and frustrated academics within and outside its community. At the hear of CMS is an enduring skepticism concerning the social and ecological sustainability of prevailing ideas and forms of management and organization. Using ideas from feminist and queer theory, authors of this volume aim to generate some thinking and possibly a nascent agenda. It focuses on the future of CMS but also intertwines it with ideas as to how scholarly communities can engage in working lives differently.

Entropy considerations applied to shock unsteadiness in hypersonic inlets
The stability of curved or rectangular shocks in hypersonic inlets in response to flow perturbations can be determined analytically from the principle of minimum entropy. Unsteady shock wave motion can have a significant effect on the flow in a hypersonic inlet or combustor. According to the principle of minimum entropy, a stable thermodynamic state is one with the lowest entropy gain. A model based on piston theory and its limits has been developed for applying the principle of minimum entropy to quasi-steady flow. Relations are derived for analyzing the time-averaged entropy gain flux across a shock for quasi-steady perturbations in atmospheric conditions and angle as a perturbation in entropy gain flux from the steady state. Initial results from sweeping a wedge at Mach 10 through several degrees in AEDC's Tunnel 9 indicates the bow shock becomes unsteady near the predicted normal Mach number. Several curved shocks of varying curvature are compared to a straight shock with the same mean normal Mach number, pressure ratio, or temperature ratio. The present work provides analysis and guidelines for designing an inlet robust to off- design flight or perturbations in flow conditions an inlet is likely to face. It also suggests that inlets with curved shocks are less robust to off-design flight than those with straight shocks such as rectangular inlets. Relations for evaluating entropy perturbations for highly unsteady flow across a shock and limits on their use were also developed. The normal Mach number at which a shock could be stable to high frequency upstream perturbations increases as the speed of the shock motion increases and slightly decreases as the perturbation size increases. The present work advances the principle of minimum entropy theory by providing additional validity for using the theory for time-varying flows and applying it to shocks, specifically those in inlets. While this analytic tool is applied in the present work for evaluating the stability of shocks in hypersonic inlets, it can be used for an arbitrary application with a shock.

Application of compound compressible flow to hypersonic three-dimensional inlets
A method for correcting flow non-uniformities and incorporating multiple oblique shocks waves into compound compressible flow is presented. This method has several applications and is specifically presented for the problem of creating a streamline-traced hypersonic three-dimensional inlet. This method uses compound compressible flow theory to solve for the freestream flow entering a pre-defined duct with a desired downstream profile. This method allows for multiple iterations of the design space and is computational inexpensive. A method is also presented for modeling a laminar or turbulent boundary layer to compare inlet designs and to determine the viscous correction to the inlet. Two different Mach 6 designs were evaluated, with a rectangular capture area and circular combustor with a uniform temperature, pressure, and Mach number profile. Comparison with other three-dimensional inlets indicates those designed with this method demonstrate good inviscid performance. These inlets also have the ability to correct incoming flow non-uniformities.

Gis Representation and Assessment of Water Distribution System for Mae La Temporary Shelter, Thailand
ArcGIS is used to analyze water access in Mae La, Thailand, home to 45,000 residents living as refugees in a temporary camp. Drinking water for the shelter is supplied at public tap stands while water for hygienic purposes such as bathing and laundry is available via covered rope-pump wells which reach shallow ground water; stream and river surface water; and hand-dug wells. In all, 7,117 homes were identified using Google Earth and the corresponding proximity to the nearest tap stand and rope-pump well was calculated. ArcGIS was used together with an EPANET water-distribution model created by Rahimi (2008) to evaluate the predicted daily volume of drinking water available per home. Overall this research shows that the vast majority of residents in Mae La have sufficient access to water. Homes located further than 115 meters from a tap stand, located further than 180 meters from a rope-pump well, or having access to less than 50 liters of water per day were considered a cause for concern. Approximately one in four homes met these criteria. Only 5% of homes are located more than 115 meters from a tap stand. Approximately 14% of homes did not meet the rope-pump proximity criterion, and 15% of homes did not meet the available volume criterion. The tap-stand proximity results provide a much higher degree of confidence compared to the other results. Alternative sources for hygienic water besides rope-pump wells exist, suggesting the number of homes with sufficient access to hygienic water is likely underestimated. Flow rates, predicted by the EPANET model, are highly dependent on the elevation of distribution system infrastructure points (e.g. storage tanks and tap stands), which are difficult to determine accurately.Thus, while the final results show one in four homes are a cause for concern, the reliability of the rope-pump well proximity assessment and volume per home assessment is insufficient, and the findings could be overly pessimistic.

Conceptualising horizontal politics
This project investigates the likelihood of a distinctive ideology emerging from what are known as ‘horizontal’ political movements – those which, in brief, aim to operate non-hierarchically guided by principles such as affinity – and furthermore to identify the potential components of such an ideology. The methodology is broadly based on that developed by Freeden, namely an analysis of the conceptual morphology of the ideas put out by horizontal movements. The sources used derive largely from the output of the movements themselves in various forms. I conclude that horizontal politics does have a recognisable ideological configuration, and that this is distinctive from other related ideologies such as anarchism.
