Copycatting the smell of death: Deciphering the role of cadaveric scent components used by detection dogs to locate human remains

Human remains detection dogs (HRDD) are commonly used by law enforcement agencies to search for cadavers. Biological material is typically used as a training stimulus, also called aids, to train dogs to recognize the smell of cadavers. While HRDD training approaches have received extensive attention, information remains limited on the olfactory cues used to train them. Here, we aimed to decipher the chemical basis of detection dog olfaction. Five specific objectives were explored to precise whether the composition or the concentration of the training aids drives the HRDDs responses. We recorded the behavioral responses of four HRDDs exposed to different cadaveric-like smells. We found that HRDDs recognized a simplified synthetic aid composed of cadaveric compounds. The lowest concentration at which HRDDs continued to perceive the cadaveric smell was determined. HRDDs were not impacted by slight modifications to the chemical composition of a blend of odors that they have been trained with. HRDDs associated sulfur and nitrogen compounds as human cadaver. Our findings highlight a lack of specificity of HRDDs to cadaveric compounds, which could lead to error of detection. Moreover, all dogs did not positively respond to the same blends, despite being trained with the same aids and procedure. However, we confirmed that dogs could be trained with a simplified blend of molecules. The chemical composition of a training aid has, therefore, high consequences on the performance of the trained animal, and this conclusion opens additional questions regarding olfaction-based detection animals.     

Not in our name: collective identity of the Serbian Women in Black

The Belgrade-based activist group Women in Black has been for twenty years now articulating a feminist anti-war stance in an inimical socio-political climate. The operation of this anti-patriarchal and anti-militarist organization, which has resisted numerous instances of repression, has not been until now systematically approached from a social movement perspective. This paper draws upon a range of empirical methods, comprising life-story interviews, documentary analysis and participant observation, to address the question as to how it was possible for this small circle of activists to remain on the Serbian/post-Yugoslav civic scene for the last two decades. My central argument is that a consistent collective identity, which informs the group's resource mobilization and strategic options, holds the key to the surprising survival of this activist organization. I apply recent theoretical advances on collective identity to the case of the Belgrade Women in Black with the view of promoting a potentially fruitful cross-fertilization between non-Western activism and the Western conceptual apparatus for studying civic engagement.     

Anomalous Anterior Papillary Muscle as an Autopsy Finding in Two Cases

Anomaly in the anterior papillary muscle (APM) is known to cause left ventricle outflow tract (LVOT) obstruction, and this rare congenital condition could be a cause of sudden cardiac death. This anomaly and its hemodynamic effects is similar to valvular heart disease. In our two described cases, in which cause of death was, respectively, hypertrophic cardiomyopathy and suicide by hanging, the cephalad portion of the left APM was inserted directly into the ventricular surface of the anterior mitral leaflet and chordae tendineae were absent in the area of the direct anomalous muscle insertion; the aberrant papillary muscle was very large and showed an exaggerated anterior displacement within the left ventricular cavity. The described anomaly is a cause of LVOT obstruction. This condition is considered to be rare, although incidence estimates do not exist. In the absence of other possible causes, this finding may indicate arrhythmia as being the immediate cause of death.     

EU Climate Change Litigation,the Role of the European Courts,and the Importance of Legal Culture

The purpose of this article is to show it is only in light of legal culture that climate change jurisprudence in the European Union can be explained. Examining the case law concerning the EU Emissions Trading Scheme, this article demonstrates that climate change proceedings in the European Union raise questions that stand at the heart of the EU legal order; that is, they demand that the boundaries of the EU's regulatory competences are drawn. In effect, the EU courts focus on ensuring that EU climate change laws are in accord with the rule of law or, in the context of EU law, the borders of the EU's environmental regulatory powers. As such, this article shows that attention needs to be given to the interaction between climate change laws and the constitutional role of the EU judiciary. These interactions are considered here together with the contingency of EU climate change litigation on EU legal culture.
