Artifacts Caused by Leaf-Cutting Ants of the Genus Atta (Hymenoptera: Formicidae): Postmortem Bite Injuries and the Tearing of Clothes

Ants are one of the first insects to find an exposed cadaver and can be present during all stages of decomposition. Although these organisms are not commonly used in postmortem interval estimates, they are to be taken into account on criminal investigations involving human corpses, since they can leave bite marks that can be mistaken for antemortem or perimortem injuries, which could be misleading when ascertaining the occurrence of abuse or physical altercation during a crime. A few studies report the action of ants on human cadavers and even though leaf-cutting ants of the genus Atta are frequently encountered in succession studies that use animal carcasses, there are no records of these fungus-growing species on human corpses. Atta is a genus restricted to the New World, ranging from northern Argentina to southern United States and acts as one of the most conspicuous neotropical herbivores. In this study, we report three cases of violent death that illustrate the impact of ants, especially those of the genus Atta, in a forensic setting. We compare the patterns displayed by postmortem bite injuries caused by leaf-cutter ants and other common species with less robust mandibles. We also present the capability of Atta ants to create artifacts by cutting victim’s clothes in a crime scene, contributing to the knowledge of ant-mediated confounding factors in crime scene investigation.     

The Art of Not Being Quite So Governed: An Examination of the Work of the “Critical” Journal

Michel Foucault in his lecture “What is Critique?” argues that criticism offered a response to the state's developing art of governing in the fifteenth and sixteenth centuries. Instead of accepting the state's way of governing, critics presented alternative visions of not being quite so governed or of not being governed thusly. Similarly, in the latter half of the twentieth century, factions within academic disciplines also rejected their disciplines' mode of governing and created alternatives. In response to the desire to make political science more relevant and visible, the Caucus for a New Political Science formed as an alternative to the American Political Science Association. A similar trend occurred in other disciplines. Over the next few decades a number of academic journals were founded that included the word “critical” in their titles or explicitly stated a “critical” aim or approach. However, even dissenting academic groups, like the Caucus for a New Political Science, began to be reabsorbed within their disciplinary homes. With time, many of these groups succumbed to a degree of professionalization that perhaps inhibited their larger aspirations. As Foucault argues, the critical attitude does not reject governing altogether; it is not a call for anarchy. Rather, it demands an alternative to the current governance. The question becomes how to maintain the critical attitude while also building alternative institutions. Does institution building attenuate critique? And what then is critique? This article reflects on these questions by providing a brief study of “critical” disciplinary reorganizations, with greater attention to the Caucus for a New Political Science and its journal, New Political Science.

Establishing Tobacco Origin from Pollen Identification: An Approach to Resolving the Debate

Previous research into pollen content of tobacco resulted in a debate. We address this debate and determine that pollen analysis may be able to assist with identifying geographical origin of tobacco. However, the value of any results should be assessed on a case‐by‐case regional basis until sufficient database information is available for an objective interpretation to be undertaken on a global basis. As a first step toward developing comparative data for South America, we analyzed a tobacco sample from Brazil in an effort to identify signature taxa from the state of Minas Gerais. We also assessed the role of honey additives to tobacco to assess this issue. Comparing the data to previously published data, we conclude that pollen signatures can distinguish broad geographic areas. We conclude that this forensic interpretation framework needs to be developed in context of the National Academy of Sciences recommendations for tightening methods in forensic science.
