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.     

Comparing Putin’s and Brezhnev’s Policies toward the Middle East

This article compares Moscow’s and Washington’s foreign policies toward the Middle East in 1982 and 2008. In 1982, Moscow and Washington each had a distinct set of friends and foes. In 2008, Washington still has a distinct set of friends and foes, but Moscow has relatively good relations with all governments and most major opposition movements in the region—the only exceptions being Al Qaeda and its affiliates. It is argued that Putin’s policy toward the Middle East is not really aimed at displacing the U.S. in the region, but protecting Russia and Russian interests from Al Qaeda and its allies. Indeed, a continued American presence in the region serves to protect Russian interests in the region.

How Americans Think About Trade: Reconciling Conflicts Among Money, Power, and Principles

Trade has again emerged as a controversial issue in America, yet we know little about the ideas that guide American thinking on these questions. By combining traditional survey methods with experimental manipulation of problem content, this study explores the ideational landscape among elite Americans and pays particular attention to how elite Americans combine their ideas about commerce with their ideas about national security and social justice. We find that most American leaders think like intuitive neoclassical economists and that only a minority think along intuitive neorealist or Rawlsian lines. Among the mass public, in contrast, a majority make judgments like intuitive neorealists and intuitive Rawlsians. Although elite respondents see international institutions as promising vehicles in principle, in practice they favor exploiting America's advantage in bilateral bargaining power over granting authority to the World Trade Organization. The distribution of these ideas in America is not arrayed neatly along traditional ideological divisions. To understand the ideational landscape, it is necessary to identify how distinctive mentaal models—mercantilist, neorealist, egalitarian, and neoclassical economic—sensitize or desensitize people to particular aspects of geopolitical problems, an approach we call cognitive interactionism.     

Political Consequences of the New Inequality

This article proposes agendas for teaching and research about shifting global patterns of equality and inequality, a very different agenda than was appropriate when the last undergraduate professor was president of ISA, almost forty years ago. Today, unlike in that Cold War world, formal democracy is flourishing, state power is diminishing, gender inequality has diminished, and income inequality has risen. Consequences of these new patterns that demand our attention as teachers and scholars include: (1) more frequent protracted social conflicts, (2) a newly politicized sphere of international public health, (3) the new global gender politics, (4) the new global politics of the super-rich, and (5) the new politics and ethics of the world's privileged, a group that includes most ISA members and most of our students. Our responsibilities as teachers have grown, in part, because popular media present a decreasingly coherent picture of each of these patterns; and that incoherence, itself, may help sustain global inequalities.     

Covid-19 Pandemic,Social Mitigation and Taxation: The Open Veins of Inequality in Latin America

The pandemic of Covid-19 has exposed the veins of inequality in Latin America. With a socioeconomic disaster looming, social emergency policies seemed inevitable. Yet while governments argue over the continuity of such policies and whether the fiscal rules in place should be respected, no sustainable response has come out. This essay problematises whether the pandemic could represent a critical juncture to forge ahead with political narratives that highlight tax exemptions and privileges enjoyed by the rich. We analyse the mitigation measures adopted by Argentina, Brazil, Chile and Uruguay and their repercussions on the debate surrounding progressive tax reforms to fund social schemes.     

Examination of Hacking and Blunt Force Skeletal Trauma

Hacking trauma is prevalent in forensic cases involving genocide and dismemberment, but research into the identification of this type of trauma is lacking. The present study examines characteristics of hacking and blunt force skeletal trauma in order to determine if there is a point at which blunt force trauma becomes distinguishable from hacking trauma. Ten implements with a range of blade angles (i.e., the striking surface of the implement) were used in conjunction with a controlled-force hacking device to impact 100 limb bones of white-tailed deer (Odocoileus virginianus). Observations of the trauma included the occurrence and degree of fragmentation, the entrance widths of the impacts, and composite scores of six hacking characteristics, especially the distinctive V-shaped kerf. ANOVA tests and regression analyses were used to assess the relationships between these characteristics and the blade angles. A significant relationship (p-value = 0.011) was found between the composite hacking scores and the blade angles, indicating that blunt force and hacking trauma can be distinguished. The entrance widths of the impacts exhibited a significant relationship with the blade angles (p-value = 0.037). There was also a significant relationship between the visibility of a V-shaped kerf in the bones (p-value = 0.003), with visibility decreasing around the 60° blade angle. These data should assist in establishing guidelines to differentiate hacking and blunt force skeletal trauma in cases where the implement is on a spectrum between sharp and blunt.
