An investigation of model forensic bone in soil environments studied using infrared spectroscopy

Infrared spectroscopy has been used to examine changes to bone chemistry as a result of soil burial. Pig carcasses were buried as part of a controlled field study, and pig bone was used in soil environments established in the laboratory. The variables of species type, bone pretreatment, soil type and pH, moisture content, temperature, and burial time were investigated. The crystallinity index (CI) and the organic and carbonate contents of the bones were monitored. The data revealed decreasing trends in the organic and carbonate contents and an increase in the CI of the bone with burial time. An acidic soil environment and soil type are the factors that have the most influence on bone chemistry as a result of burial. The study demonstrates the potential of infrared spectroscopy as a straightforward method of monitoring the changes associated with aging of bones in a variety of soil environments.     

Between Border and Bazaar: Central Asia’s Informal Economy

ABSTRACT

The disintegration of the Soviet Union spurred a transnational trade in consumer goods. Bazaars, which proliferated across the former Soviet Union, including in Kazakhstan and Kyrgyzstan that is the focus of this article, became nodes in this informal trade. This article makes three arguments: (i) Soviet successor states capitalised on the new informal economy which provided employment to millions when economies were in decline. Conversely, ongoing developments, particularly in Kazakhstan, seek to modernise the bazaars that emerged after the Soviet Union. (ii) The movement of people and goods – between border and bazaar, and in case of re-exports, on to another border – are illustrative of a multi-dimensional informal economy evidenced in rent extraction, regulation of bazaars, and in trader networks. (iii) The bazaar-centred economy relies on checkpoint politics that establish border regimes, enabling mobility.     

Governance of professional sports leagues—Cooperatives versus contracts

Historically, European team sports leagues were run by their respective national and international associations and were legally independent from the professional clubs playing in these leagues. Recently, European leagues have adopted an organizational form similar to their North American counterparts who are organized since their beginning in a cooperative-like manner. Based on a comparative institutional analysis, we explain the advantages of the cooperative form of league organization over contractual governance. With our four-stage game-theoretic model, we show that contractual governance of sports leagues leads to larger investment distortions than cooperative league organization.
