The results of laboratory experiments on nitroglycerine toxicity detected by histological and cytological indices are presented, using Danio rerio as a case study. For the first time, there are shown the changes in liver and kidneys, both at tissular and cellular levels, induced by administered concentrations of nitroglycerine. The results obtained appear to be important for water bodies’ preservation and elaboration of MPC standards. The intake of nitroglycerine into water bodies is due, mainly, to discharge from pharmaceutical enterprises, demolition works, and outflow from explosives storehouses. Fish turned out to be sensitive to nitroglycerine as indicated by histological and hematological indices. Maximum permissible concentration, MPC, for Danio rerio is determined to be equal to 0.5 mg/l.

Do employers penalize Asian-origin workers for personality-related reasons during real hiring decisions? Current theoretical approaches—the Model Minority Myth perspective and the Heterogeneity approach—provide conflicting predictions as to the nature of an Asian-origin personality penalty, if one exists. Furthermore, evidence of an Asian-origin personality penalty is typically derived from laboratory experiments based on evaluation of fictitious material rather than from real hiring decisions based on face-to-face interviews and hiring deliberations. To fill the empirical gap and resolve theoretical tension, I provide evidence of an Asian-origin personality penalty from a case study of hiring at a Silicon Valley high-technology firm. Drawing from quantitative and qualitative data, I demonstrate how the firm’s decision makers penalize Asian-origin job candidates during hiring decisions for their judged personality traits in a way that does not fully coincide with either theoretical approach, and I propose a theoretical model to describe the personality “content” of the Asian-origin personality penalty as it occurs in real hiring decisions.

SUMMARYThis paper is a continuation of a previous work of authors, Scagliaet al. [G. J. E. Scaglia, L. M. Quintero, V. Mut and F. Di Sciascio, “Numerical methods based controller design for mobile robots,”Robotica27(2), 269–279 (2009)]. A method is presented to choose the controller parameters such that, the values of the control actions do not exceed the maximum allowable and the tracking errors tend to zero. In addition, the analysis of the controller design parameters is included. The experimental results (laboratory experiments and a real world application) demonstrate the efficiency of the controller.

Private information and the commitment problem are central to the rationalist theory of war, but causal evidence is scarce, as rationalist explanations for war are difficult to test with observational data. I design laboratory experiments to isolate the effects of private information and the commitment problem on the risk of conflict. I find that the commitment problem sharply increases the incidence of conflict, but there is no significant difference in conflict incidence with or without private information in the shadow of shifting power. I also investigate the realism of the positive experimental results with a case study of Japan’s decisionmaking on the eve of the Pacific War. The permutation of formal, experimental and historical methods applies the strength of one method to compensate for the weakness of another. Convergent results from the different methods strengthen the causal inference.

Content and Language Integrated Learning (CLIL) is bilingual education whereby students do not only study a second language, in addition to their native tongue, but learn a school subject in that foreign language. This study is based on the teaching of chemistry in English to Grade 9 students in the Republic of Bulgaria. Correlation exists between the performance of students in chemistry taught in English with their performance in English in Grade 8 and Grade 9. There is also a correlation between their performance and gender and regarding the second language chosen. In fact, students who opted for Russian and Spanish fared better than those who opted for German and French. More laboratory experiments at school, lessons incorporating interesting games, and stimulating interactive projects were recommended by students as useful tools to improve their scientific literacy.
