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.     

Doing Well vs. Feeling Well: Understanding Family Dynamics and the Psychological Adjustment of Chinese Immigrant Adolescents

Despite their average high levels of educational achievement, Asian American students often report poor psychological and social adjustment, suggesting an achievement/adjustment paradox. Yet, the reasons for this paradox remain unclear. Drawing on 5-year longitudinal qualitative interview data, this paper compares the family dynamics of two groups of adolescents from Chinese immigrant families: non-distressed adolescents (n = 20) who have high levels of academic achievement and high levels of psychological well-being; and distressed adolescents (n = 18) who have high levels of academic achievement but low levels of psychological well-being. Findings suggest that the two groups of families differed in parenting approaches after migration, parent–child communication, parental expectations, and parent–child relations. Implications for Asian American adolescent and youth development are discussed.

The roles of foreign aid and education in the war on terror

This paper presents a theoretical framework and some empirical results showing that the level of foreign aid received reduces the supply of terrorist attacks by recipient countries, as does the recipient country’s level of education. Due account is taken of endogeneity problems in producing these results. They suggest that Western democracies, which are the main targets of terrorist attacks, should invest more funds in foreign aid with a special emphasis on supporting education.     

The extent of the population paradox in the Hungarian electoral system

The Hungarian mixed-member electoral system, adopted in 1989, is one of the world’s most complicated electoral systems, and, as this paper demonstrates, it suffers from the “population paradox.” In particular, the governing coalition may lose as many as 8 seats either by getting more votes or by the opposition obtaining fewer votes on each territorial list.     

Does Interest-Based Bargaining (IBB) Really Make a Difference in Collective Bargaining Outcomes?

This study seeks to identify what specific kinds of compromises result from IBB, or interest-based bargaining, and what differentiates agreements that are reached using this method from the ones that are negotiated through more traditional forms of collective bargaining. The authors compare the changes to collective agreements in 19 cases that used interest-based bargaining and the changes to agreements in 19 cases that used more traditional forms of negotiation. Their analysis reveals that clauses dealing with joint governance and organizational innovation underwent more changes when the parties adopted the IBB approach. In addition, IBB has given rise to more union concessions.     

The political economy of sugarcane flexing: initial insights from Brazil,Southern Africa and Cambodia

In the context of rising resource demand, agricultural crops such as sugarcane are being promoted for their multiple uses in different commodity markets and as alternatives to fossil fuel equivalents (i.e. as a source of biofuel, bioelectricity and bioplastic). These commodities are also produced on an increasingly flexible basis, as sugarcane mills respond to price signals and switch between different crop uses. This paper offers a preliminary exploration into the politics of this latest development in the capitalist industrialization of agriculture. It does so by focusing primarily on flexing in Brazil and highlighting the role of the state in both creating markets for non-food products that sugarcane mills can now switch between and managing the tensions that arise from this. These tensions have concerned consumer prices for fuel, control of distribution infrastructure and conditions of land conversion, each prompting political interventions by the state. The paper then suggests how this same process is taking place, albeit shaped by different contexts, in Southern Africa and Cambodia. It concludes with some key questions for further research: is flexing eroding the distinction between crop regimes? How do primary processors decide what their product mix will be? And on what basis do state actors support flexing between agricultural products and investments in so-called bio-refineries?     

Understanding food security and international security links in the context of climate change

Food production has been changing significantly in recent years as a result of climate change and of growing demand for food. This article aims to understand the link between food security and international security in the context of climate change, applying a systematic and qualitative analysis of the literature using the bibliometric method. This research observes that climate change tends to affect agricultural productivity, exposing societies to risk and the need for migration. However, good governance, together with international cooperation, can reduce the hazards of food insecurity, strengthening ties between countries and stimulating a fairer and more inclusive form of international trade.
