Illuminations and Shadows from Jury Simulations

In the 18 years since authors in Law and Human Behavior's special issue on simulation research called for more realistic jury simulations, jury simulations of all kinds have proliferated. While simulations in general represent a significant improvement over nonempirical armchair speculation about jury behavior, the more ecologically valid features of recent simulations increase both the quality and the persuasiveness of simulation results. Still missing, however, are theories and a data base that will signal when these more elaborate and expensive design features are crucial.     

Developing a new scoring method to evaluate human decomposition in a humid,continental (Dfb) climate in Quebec

The published literature shows a lack of methods to evaluate the patterns and extent of decomposition of human remains and to estimate the post-mortem interval (PMI) in humid, continental (Dfb) climates such as Quebec. The aim of this study was to address this gap in the current knowledge base by providing the first observations from human corpses studied under controlled conditions in Quebec. A 12-month study was conducted at the site for Research in Experimental and Social Thanatology; the first human taphonomy facility in Canada. Six human donors with known time of death were deposited across spring (n = 1), summer (n = 3), and autumn (n = 2) 2021. The lack of suitability of the total body score method to evaluate the extent of decomposition at the facility prompted the development of a new scoring system based on the macromorphoscopic changes observed. The scoring system was applied to the donors to evaluate decomposition throughout seasons. All donors followed comparable decomposition trajectories, regardless of the season of deposition. Eighty-five percent of taphonomic patterns appeared in the first 25 experimental days or 5000 Kelvin accumulated degree days (350 ADD). Extensive desiccation of tissues was observed at a median of 21 experimental days across donors, resulting in a plateau within decomposition with no extensive skeletonization. To the authors' knowledge, this is the first published report of experimentally observed desiccation in such a form in a Dfb climate. This study provides new data on the types of decomposition patterns to expect in forensic investigations in southern Quebec and comparable climates.     

Preliminary Studies into the Characterization of Chemical Markers of Decomposition for Geoforensics*

Abstract: In this paper, we report the results of our preliminary studies into chemical characterization of the fluids produced during decomposition in the absence of a soil matrix. Pig (Sus domestica) carcasses were used to model the human decomposition process in two separate locations, Western Australia (Perth) and Canada (Oshawa). Analysis involved simple dilution and filtration of the decomposition fluids followed by gas chromatography–mass spectrometry. Several previously unreported compounds were detected in the decomposition fluid samples during the trials, including benzeneacetic acid, benzenepropionic acid, 2‐piperidone, and isocaproic acid. Possible biosynthetic pathways for some of the compounds produced are proposed. Further research trials are required, particularly in the presence of soil matrices.     

Freezing skeletal muscle tissue does not affect its decomposition in soil: Evidence from temporal changes in tissue mass,microbial activity and soil chemistry based on excised samples

The study of decaying organisms and death assemblages is referred to as forensic taphonomy, or more simply the study of graves. This field is dominated by the fields of entomology, anthropology and archaeology. Forensic taphonomy also includes the study of the ecology and chemistry of the burial environment. Studies in forensic taphonomy often require the use of analogues for human cadavers or their component parts. These might include animal cadavers or skeletal muscle tissue. However, sufficient supplies of cadavers or analogues may require periodic freezing of test material prior to experimental inhumation in the soil. This study was carried out to ascertain the effect of freezing on skeletal muscle tissue prior to inhumation and decomposition in a soil environment under controlled laboratory conditions. Changes in soil chemistry were also measured. In order to test the impact of freezing, skeletal muscle tissue (Sus scrofa) was frozen (?20 °C) or refrigerated (4 °C). Portions of skeletal muscle tissue (～1.5 g) were interred in microcosms (72 mm diameter × 120 mm height) containing sieved (2 mm) soil (sand) adjusted to 50% water holding capacity. The experiment had three treatments: control with no skeletal muscle tissue, microcosms containing frozen skeletal muscle tissue and those containing refrigerated tissue. The microcosms were destructively harvested at sequential periods of 2, 4, 6, 8, 12, 16, 23, 30 and 37 days after interment of skeletal muscle tissue. These harvests were replicated 6 times for each treatment. Microbial activity (carbon dioxide respiration) was monitored throughout the experiment. At harvest the skeletal muscle tissue was removed and the detritosphere soil was sampled for chemical analysis. Freezing was found to have no significant impact on decomposition or soil chemistry compared to unfrozen samples in the current study using skeletal muscle tissue. However, the interment of skeletal muscle tissue had a significant impact on the microbial activity (carbon dioxide respiration) and chemistry of the surrounding soil including: pH, electroconductivity, ammonium, nitrate, phosphate and potassium. This is the first laboratory controlled study to measure changes in inorganic chemistry in soil associated with the decomposition of skeletal muscle tissue in combination with microbial activity.     

From Identity to Queer Politics: Shifts in Normative Heterosexuality and the Meaning of Citizenship

This essay argues that there is occurring in the United States something of a shift from identity to queer politics, which is paralleled by changes in the social patterns of normative heterosexuality. I consider some of the implications for thinking about sexual citizenship. In particular, I comment on the ambivalent relationship of a queer politics to a politics of citizenship.     

The call of the wise baby in Chaplin's The kid

In this study we seek to understand the gendered dynamics of bearing witness, remembering, and mourning in contemporary Israeli society by examining the performative practices of one protest movement, Women in Black (WiB). Our focus is on the Haifa chapter of the movement, whose vigils we observed over a seven-year period. After a brief overview of the literature regarding national remembering and commemoration in Israel, the formation of WiB and its place in Israeli political life and discourse, we move to our analysis of the vigil. We argue that by analyzing WiB's vigil as a performance, we are able to complicate the discussion concerning women, performance and remembrance in general and in Israel in particular. We find that through their performance WiB disrupts the current “economy of memory” in Israel; by remembering and performing that which many would like to remain forgotten – the occupation which followed the 1967 War and its consequences – it engages in a project of “transformative remembering,” which disturbs its audience's equanimity and forces it to review its past.
