Dermestes maculatus (Coleoptera: Dermestidae) development under fluoxetine effect using two drug administration models

Fluoxetine is a selective serotonin reuptake inhibitor, commonly used for the treatment of a variety of psychopathological conditions. As such, fluoxetine may be expected to appear in clinical and forensic cases. Dermestes maculatus De Geer (Coleoptera: Dermestidae) has been recognized as a relevant component of the insect fauna associated with decomposing human and animal remains. Experiments were conducted to study the effect of fluoxetine on developing D. maculatus using two‐drug administration models: a non‐living animal model (pork muscle) and a living one (Sus scrofa L. pigs). We assessed the duration of immature stages and total life cycle, as well as morphological parameters (body length, cephalic width, and weight). The effect of fluoxetine was studied at an overdose concentration: In the non‐living animal model the drug was mixed with macerated pork muscle (2000 mg/kg) and in the living animal model, pigs were given the drug orally (833 mg/kg). A control was used for each model. Daily observations were performed from the beginning to the end of the experiments. GC‐MS was used for drug detection and quantification. There were no statistically significant differences in the duration of immature stages, life cycle, larval mortality, morphological parameters, or sex ratio, between treatment and control, regardless of the drug administration model. Given that fluoxetine had no detectable effect on the development of D. maculatus, detection of this drug in forensic situations would not compromise the accuracy of PMI estimations.     

Authoritarian Regimes and Their Permitted Oppositions: Election Day Outcomes in Cuba

Electoral opposition to long‐established authoritarian regimes may be loyal or rejectionist. Loyal oppositionists vote to send a selective signal to rulers; rejectionist oppositionists vote blank or void the ballot in full disapproval. In Cuba, the number of candidates equals the number of seats, yet voters may vote blank, void, or selectively (choosing some but not all candidates on the ballot), although the Communist Party has campaigned for all candidates. This article uses a unique dataset for Cuba's 2013 National Assembly elections to study aggregate opposition outcomes. It shows the emergence of a loyal opposition, which sometimes votes for and sometimes against Communist Party candidates. The rejectionist opposition, stable over time, never votes for Communist Party candidates; it is found where the Communist Party behaves monopolistically. This combined opposition has better national‐level political information; it comes from more educated or larger urban areas or areas closer to Havana.

Detracking America's schools: Equity at zero cost?

Schools across the country are ending the practice of grouping students based on ability, in part, because of research indicating that tracking hurts low-ability students without helping students of other ability levels. Using a nationally representative survey conducted by the National Center for Education Statistics, (NCES) we reexamine the impact of tracking on high school student achievement through the estimation of a standard education production function. This approach allows us to control for the possibility that track is correlated with factors such as class size and teacher education. In addition, we address the possibility that there are unobserved student or school characteristics that affect both achievement and track placement. Our results indicate that abolishing tracking in America's schools would have a large positive impact on achievement for students currently in the lower tracks, but that this increase in achievement would come at the expense of students in upper-track classes.     

Mobilizing from the Margins: Domestic Citizen Politics and Yasukuni Shrine

Prime Minister Koizumi’s six consecutive annual visits to Yasukuni shrine played a key role in initiating a new phase of domestic citizen political mobilization not seen since the early 1970s. This paper is based on field research during the Koizumi years (2001–2006) centering on domestic groups that conduct activities in “protection” of or “opposition” to Yasukuni shrine. As a study of street-based politics, this paper seeks to uncover the processes, strategies, and outcomes of citizen responses to elite political action at Yasukuni Shrine as well as explore meaning of their actions within the context of Japan’s democratic polity.

Forensic toxicological study on adipocere formation in submerged cadavers of female albino rats intoxicated with cadmium

There is a dearth of information on the mutual interaction between metal intoxication and adipocere formation. Herein, 40 adult female albino rats were distributed into two equal groups, one used as control while the other orally administered single dose of cadmium chloride (CdCl₂) 225 mg/kg·bw (LD_min). Control group was killed by cervical dislocation. Half of dead rats of both groups were subjected for determination of iodine value and estimation of cadmium (Cd) residues while the other half of both groups were submerged in opened glass container previously filled with 4 L dechlorinated tap water kept in closed room with an open air access (one cadaver/container). Gross morphological changes of submerged cadavers were recorded weekly along the experiment. At the end of the experiment, after 3 months, samples were collected again for iodine value determination and estimation of Cd residues. The obtained results revealed the depressant effect of Cd toxicity on development of adipocere. Cd residues were found in different tissues of cadavers at time of death with the highest amount in the intestines followed by the liver and kidneys, then lungs, adipose tissue, muscles, and finally the bones. After 3 months of water submersion, tissues exhibited significant decrease in the amount of Cd residues but to a limit that was still detected. This study concluded the possibility of detection of Cd residues even after adipocere formation. Additionally, it shed light on the possibility of the interference of environmental pollution with the natural rate of decomposition especially adipocere formation.     

The politics of return: exploring the future of Syrian refugees in Jordan,Lebanon and Turkey

Abstract

Although the Syrian conflict continues, local and global stakeholders have already begun to consider the return of the six million refugees, especially as neither the option of local integration in the countries of first asylum nor that of resettlement to third countries is seen as a realistic possibility. Elaborating on the return debates in Turkey, Lebanon and Jordan, we relate the politicisation of this question to the growing acceptance of the option of voluntary and involuntary repatriation in the international refugee regime as well as to policies and public opinion. We argue, based on empirical fieldwork, that any debate about the return of Syrian refugees is problematic, since the conditions of safety, voluntariness and sustainability are not fulfilled. Further, returns should not be left entirely to the individual hosting states and actors in the region but should be carried out in collaboration with representative authorities in Syria and the mediation of international organisations upon full resolution of conflict.     

Postmortem Changes of Female External Genitalia and Their Importance in Suspected Sexual Abuse

Examination of the female external genitalia to assess for sexual abuse is performed in living individuals, and the interpretation of the findings is based on evidence-based studies. However, in the deceased, no such studies are available, and postmortem changes could present as suspicious findings that can be mistaken for trauma. Patches of discoloration in the hymen were reported previously in one case as hypostasis (i.e., livor and lividity), and based on this finding, it was listed as a finding that is not associated with trauma. This was a retrospective study that was conducted in the Center of Forensic and Legal Medicine in Dammam, Saudi Arabia over a 4-year period. The study included 30 deceased women in whom photographic documentation of their external genitalia was assessed for postmortem changes. The postmortem interval ranged from less than 24 h to more than 100 days, and the ages of these deceased women were in the 20–40 year-old age group. In cases where the hymen, vagina, and/or fossa navicularis were clearly visible, none of these areas showed any hypostatic discoloration. A comparison between antemortem and postmortem appearance of the hymen in one case clearly showed the absence of hypostatic changes in the hymen. In conclusion, any discoloration of the external genitalia that is detected in a female decedent requires serious consideration.
