How gender, majors, religion and mental health affect the justified death attitude?

Background: Death penalty and euthanasia are disputed practices in the world. However, they are considered "justified" by their proponents. We newly developed a scale for assessment of the attitude toward justified death, which determines "hot cognition" using a number of scenarios. Objectives: This study aimed at assessing the effects of the major demographic items including gender, major, religion, and mental health on the justified death attitude. Methods: A total of 481 participants including 419 university students and 62 seminarians participated in the study in Tehran, Iran. The Persian versions of the justified death attitude scale and the general health questionnaire-12 were used for data collection. Data were analyzed using the multivariate analysis of variance. Results: Capital punishment was suggested more frequently for rape and drug trafficking and less frequently for murder, and infrequently for adultery. Men and religious subjects showed a more positive attitude toward execution. Furthermore, most of the subjects did not agree with euthanasia; surprisingly, active euthanasia was more acceptable than passive euthanasia. Finally, death penalty and euthanasia did not show an association with mental health. Conclusions: Individual characteristics like gender, major, and religiosity could significantly affect the attitude of people toward justified death. Further studies including neuropsychological methods are suggested. © 2017, Iranian Journal of Psychiatry and Behavioral Sciences

Preparation and characterization of 100% bio-based polylactic acid/palmitic acid microcapsules for thermal energy storage

Abstract Phase change materials (PCM) have gained extensive attention in thermal energy storage applications. In this work, microencapsulation of vegetable-derived palmitic acid (PA) in bio-based polylactic acid (PLA) shell by solvent evaporation and oil-in-water emulsification was investigated. Fourier transform infrared spectroscopy and scanning electron microscopy were conducted to confirm the successful encapsulation of PA in PLA shells. Differential scanning calorimetry was performed to evaluate the thermal properties, thermal reliability, and core content of the fabricated PCM microcapsules (microPCM). Through a series of parametric studies, the effects of PCM and solvent content, oil phase-to-aqueous phase ratio, as well as surfactant type and content on the morphology, particle size, and thermal properties of the PCM microcapsules were investigated. Experimental results showed that PVA was a superior emulsifier to SDS in the emulsion systems being studied. There also existed an optimal PVA concentration to reduce the average size of microPCM. When the PVA concentration was above this optimal level, the emulsifier molecules tend to form micelles among themselves. This led to the adhesion of tiny microspheres on the surface of microPCM as well as larger microPCM. In short, this work has demonstrated the possibility of using the solvent evaporation method to fabricate 100% bio-based PCM-polymer microcapsules for thermal energy storage applications
