Do So

Understanding the cognitive underpinnings of moral judgment is one of most pressing problems in psychological science. Some highly-cited studies suggest that reliance on intuition decreases utilitarian (expected welfare maximizing) judgments in sacrificial moral dilemmas in which one has to decide whether to instrumentally harm (IH) one person to save a greater number of people. However, recent work suggests that such dilemmas are limited in that they fail to capture the positive, defining core of utilitarianism: commitment to impartial beneficence (IB). Accordingly, a new two-dimensional model of utilitarian judgment has been proposed that distinguishes IH and IB components. The role of intuition on this new model has not been studied. Does relying on intuition disfavor utilitarian choices only along the dimension of instrumental harm or does it also do so along the dimension of impartial beneficence? To answer this question, we conducted three studies (total N = 970, two preregistered) using conceptual priming of intuition versus deliberation on moral judgments. Our evidence converges on an interaction effect, with intuition decreasing utilitarian judgments in IH—as suggested by previous work—but failing to do so in IB. These findings bolster the recently proposed two-dimensional model of utilitarian moral judgment, and point to new avenues for future research.

Voter Abstention

Despite the existence of an extensive literature, no definitive conclusion seems to emerge on the extent to which minorities are guaranteed by democratic rules in political systems. This paper contributes to this debate by proposing a modified Heigselmann and Krauss two-dimensional model of preferences in order to capture the role of abstention on minority representativeness. Regardless of the typology of abstention, simulation results show that voter abstention always benefits minorities.

Coating Synthesis

Two-dimensional model of the Ti-Ni coating synthesis in condition of the electron-beam treatment is suggested and investigated. The base is iron. The system of chemical reactions is written according to the phase diagram of Ti-Ni.The results of numerical investigation of the model which illustrate the role of the technology parameters in the conversion regimes are represented. Distribution of temperature and elements concentration and compounds in different time moments for different synthesis conditions are constructed. It is shown that at any process organization the synthesized material becomes chemically heterogeneous.

Role Of Parents

Introducing environment is important for children. Included in this environment is the life of living beings such as humans, animals, and plants. The role of parents is needed in introducing the living creatures. One of the living creatures that endeared children are animals, especially the pets. Therefore made educational game The Pets. With the game "The Pets" is expected to help parents to teach the children in learning about pets based on place of living and food. In this paper describes how to design and create introducing pet game based on the type of food and its habitat in two different languages . "The Pets" has the Android platform with a minimum API Level 14 is created using the game engine Construct 2. Using two dimensional model and image with interesting coloring for children, and using the application CorelDraw X4. From results of the survey, "The Pets" can provide new knowledge and can assist children in learning about pets based on place of living and food. Children who previously could not mention animals vocabulary in English, after playing "The Pets" can name them into English.

Two Dimensional Model

When swimming in close proximity, some microorganisms such as spermatozoa synchronize their flagella. Previous work on swimming sheets showed that such synchronization requires a geometrical asymmetry in the flagellar waveforms. Here we inquire about a physical mechanism responsible for such symmetry breaking in nature. Using a two-dimensional model, we demonstrate that flexible sheets with symmetric internal forcing deform when interacting with each other via a thin fluid layer in such a way as to systematically break the overall waveform symmetry, thereby always evolving to an in-phase conformation where energy dissipation is minimized. This dynamics is shown to be mathematically equivalent to that obtained for prescribed waveforms in viscoelastic fluids, emphasizing the crucial role of elasticity in symmetry breaking and synchronization.

Face Seals

The role of circumferential surface waviness in contacting mechanical face seals is examined. First, a two dimensional model is developed. The model considers waviness amplitude, surface roughness, asperity contact, hydrodynamic and hydrostatic pressures, and fluid cavitation. Given waviness, roughness, number of waves, geometry, and sealed fluid, the model predicts the fraction of load supported by fluid pressure, the relative wear rate, friction coefficient, and leakage rate. A numerical method for solving this problem is presented. Using this model, the effects of waviness amplitude, roughness, number of waves, face width, and sealed pressure on seal performance are examined. Based on these results, certain conclusions are reached concerning the role of waviness in commercial face seals. Finally, using the model, it is shown how waviness can be applied to advantage to reduce seal friction and wear rates.
