Controlling the variable of pressure in the production of test footwear impressions

Footwear impression lifting and enhancement techniques may be affected by several variables introduced during the production of test footwear impressions, thus limiting the usefulness of enhancement technique comparisons and the results obtained. One such variable is the force applied when the impressed mark is being made. Producing consistent test impressions for research into footwear enhancement techniques would therefore be beneficial. This study was designed to control pressure in the production of test footwear impressions when mimicking a stamping action. Twenty-seven volunteers were asked to stamp on two different surfaces and the average stamping force was recorded. Information from the data obtained was used to design and build a mechanical device which could be calibrated to consistently deliver footwear impressions with the same force onto a receiving surface. Preliminary experiments using this device and different contaminants on the footwear sole have yielded consistent and repeatable impressions. Controlling the variable of pressure for the production of test impressions in this study demonstrated that the differences observed were visual (due to the amount of contaminant transferred and subsequent enhancement) and did not affect the replication of outer sole characteristics. This paper reports the development of the device and illustrates the quality of the impressions produced.     

Populist possibilities and political constraints in Mexico

This article defines populism (in Latin American context) as a form of politics that is based mainly upon a personalist appeal, attracts significant popular support and, if successful, significantly redesigns social or political institutions. Neopopulism is defined as a form of populism which begins outside the state as opposed to classic populism which originates within the state. The main theoretical argument is that the study of populism can be made significant for comparative politics if we emphasise the issue of institutional redesign and then conceptualise it in structure vs agency terms. The comparative question then becomes whether a particular set of political institutions is robust enough to withstand the challenge of a charismatic individual. The empirical background is that Latin America has seen a significant number of populist movements that have indeed fundamentally altered institutional structures. By the same token, there have been an even larger number of populist attempts which ultimately failed. Having made this point, the discussion then focuses on Mexico. It seeks to understand the different sets of conditions which allowed Lázaro Cárdenas to succeed as classic populist in the 1930s, Cuauhtémoc Cárdenas to come close to success as a neopopulist in the 1980s and which greatly reduce the likelihood of successful neopopulism in the near future.     

The land grab and corporate food regime restructuring

Land grab appears to be a phenomenal expression of deepening contradictions in the corporate food regime. In particular, the end of cheap food (signaled in the 2008 ‘food crisis’) has generated renewed interest in agriculture for development on the part of the development industry, matched by a rising interest in offshore land investments, driven by governments securing food and fuel exports and financiers speculating on commodity futures and land price inflation. This paper interprets these developments as illusory solutions to a fundamental accumulation crisis of the neoliberal project. While this new (and final?) enclosure registers a restructuring of the food regime, as its geopolitical relations and productive content re-centers on Southern land and an emergent bioeconomic imperative, it is likely to only buy time (and space) in the short run for political and economic elites and a global consuming class. In the longer run, the attempt to resolve food regime contradictions by a spatial fix may well be catastrophic.     

Amended cause and manner of death certification: a six-year review of the New Mexico experience

Little is known about the amendment of death certificates (DCs) issued by medical examiners and coroners. This retrospective study examined why, how, and with what frequency cause and manner of death were amended on DCs issued by forensic pathologists over a 6-year period at the New Mexico Office of the Medical Investigator. Approximately 1% of DCs had either cause or manner of death amendments, with arteriosclerotic cardiovascular disease and intoxicants the most commonly amended and resulting causes of death, respectively. There was a significant association between manner of death and number of DCs amended (p<0.001). By percent, natural and suicide DCs were the most frequently amended. The way in which manner of death changed was significantly associated with the amount of time elapsed between DCs (p=0.04). Toxicology was the most common reason for DC amendment.
