What is moral about guilt? Acting “prosocially” at the disadvantage of others.

For centuries economists and psychologists have argued that the morality of moral emotions lies in the fact that they stimulate prosocial behavior and benefit others in a person's social environment. Many studies have shown that guilt, arguably the most exemplary moral emotion, indeed motivates prosocial behavior in dyadic social dilemma situations. When multiple persons are involved, however, the moral and prosocial nature of this emotion can be questioned. The present article shows how guilt can have beneficial effects for the victim of one's actions but also disadvantageous effects for other people in the social environment. A series of experiments, with various emotion inductions and dependent measures, all reveal that guilt motivates prosocial behavior toward the victim at the expense of others around—but not at the expense of oneself. These findings illustrate that a thorough understanding of the functioning of emotions is necessary to understand their moral nature.

Comment on “Thermal Conductivity Measurements of Some Synthetic Al2O3-CaO-SiO2 Slags by Means of a Front-Heating and Front-Detection Laser-Flash Method”

In a previous research, it was pointed out that the thermal conductivity of molten silicate may be misled, due to the current leakage through the molten sample and the error in the resistance of the hot-wire. The applicability of the hot-wire method could be verified by the prediction of the current leakage through the sample and the comparison between the measured and the reference values of the hot-wire resistance.     

Developing and Teaching a Course in “Applied Sustainability and Public Health in Civil Engineering Design” at Queen’s University, Kingston, Canada

This paper presents the writer’s pedagogical development and delivery of a new undergraduate course in applied sustainability and public health in civil engineering design in the Department of Civil Engineering at Queen’s University in Kingston, Canada. This innovative course introduces undergraduate civil engineering students to methods in sustainability indicators, life-cycle analysis, environmental input-output analysis, and risk analysis to evaluate the environmental impacts and public health impacts of civil engineering design. The paper discusses the learning objectives and course themes of preventive design, multicriteria decision making, and systems-level analysis. The course syllabus and the design project in which students were asked to design a water transmission pipeline and evaluate its environmental impacts are discussed in detail. An overview of the pedagogical methods and student evaluation tools employed in the course is given. An evaluation of learning outcomes and student impressions of the course suggest that topics on design for environment, sustainable development in an international context, and the interface between sustainability, engineering, and policy development should be included in future editions of the course.     

Phase Equilibria of “Cu2O”-“FeO”-CaO-MgO-Al2O3 Slags at PO2 of 10-8.5 atm in Equilibrium with Metallic Copper for a Copper Slag Cleaning Production

Limited data are available on phase equilibria of the multicomponent slag system at the oxygen partial pressures used in the copper smelting, converting, and slag-cleaning processes. Recently, experimental procedures have been developed and have been applied successfully to characterize several complex industrial slags. The experimental procedures involve high-temperature equilibration on a substrate and quenching followed by electron probe X-ray microanalysis. This technique has been used to construct the liquidus for the “Cu₂O”-“FeO”-SiO₂-based slags with 2 wt pct of CaO, 0.5 wt pct of MgO, and 4.0 wt pct of Al₂O₃ at controlled oxygen partial pressures in equilibrium with metallic copper. The selected ranges of compositions and temperatures are directly relevant to the copper slag-cleaning processes. The new experimental equilibrium results are presented in the form of ternary sections and as a liquidus temperature vs Fe/SiO₂ weight ratio diagram. The experimental results are compared with the FactSage thermodynamic model calculations.
