The Principle of Double Effect: Act-Types and Intentions
Objections to the principle of double effect usually concern its first and second conditions (that the act not be evil in itself, and that the good effect and not the evil effect be intended). The difficulties often arise from a rejection of the idea that acts have a moral nature independent of context, and a tendency to interpret intention as purely psychological. This article argues that the “act itself” should be understood as the act-type, and suggests that examples of evil act-types are not hard to find. It argues that the notion of intention is involved in both conditions, but in different ways. It proposes that these different ways can be interestingly illuminated by Anscombe’s distinction between acting intentionally and acting with an intention
Contemporary Jesuit Epistemological Interests
Apart from an orientation to and interest in the discernment of spirits as laid out in St Ignatius’s Spiritual Exercises, there does not exist a Jesuit epistemology as such. Compared to the numbers of Jesuit systematic theologians, scripture scholars, metaphysicians, and ethicists, there have been few Jesuit epistemologists.2 In metaphysics, Jesuits have been Thomist or Suarezian, even Platonist. In ethics, they have ranged from proportionalist through deontologist to virtue ethicist. No similar distinctive Jesuit presence is to be found in epistemology...
Just War Thought and the Notion of Peace
The goal of this chapter is to explore the notion of peace appropriate to just war thought. Some just war principles generate a number of inferences about peace
Carter-Payne homomorphisms and Jantzen filtrations
We prove a q-analogue of the Carter-Payne theorem in the case where the
differences between the parts of the partitions are sufficiently large. We
identify a layer of the Jantzen filtration which contains the image of these
Carter-Payne homomorphisms and we show how these homomorphisms compose.Comment: 30 page
CAPS Simulation Environment Development
The final design for an effective Comet/Asteroid Protection System (CAPS) will likely come after a number of competing designs have been simulated and evaluated. Because of the large number of design parameters involved in a system capable of detecting an object, accurately determining its orbit, and diverting the impact threat, a comprehensive simulation environment will be an extremely valuable tool for the CAPS designers. A successful simulation/design tool will aid the user in identifying the critical parameters in the system and eventually allow for automatic optimization of the design once the relationships of the key parameters are understood. A CAPS configuration will consist of space-based detectors whose purpose is to scan the celestial sphere in search of objects likely to make a close approach to Earth and to determine with the greatest possible accuracy the orbits of those objects. Other components of a CAPS configuration may include systems for modifying the orbits of approaching objects, either for the purpose of preventing a collision or for positioning the object into an orbit where it can be studied or used as a mineral resource. The Synergistic Engineering Environment (SEE) is a space-systems design, evaluation, and visualization software tool being leveraged to simulate these aspects of the CAPS study. The long-term goal of the SEE is to provide capabilities to allow the user to build and compare various CAPS designs by running end-to-end simulations that encompass the scanning phase, the orbit determination phase, and the orbit modification phase of a given scenario. Herein, a brief description of the expected simulation phases is provided, the current status and available features of the SEE software system is reported, and examples are shown of how the system is used to build and evaluate a CAPS detection design. Conclusions and the roadmap for future development of the SEE are also presented
The Trajectory Synthesizer Generalized Profile Interface
The Trajectory Synthesizer is a software program that generates aircraft predictions for Air Traffic Management decision support tools. The Trajectory Synthesizer being used by researchers at NASA Ames Research Center was restricted in the number of trajectory types that could be generated. This limitation was not sufficient to support the rapidly changing Air Traffic Management research requirements. The Generalized Profile Interface was developed to address this issue. It provides a flexible approach to describe the constraints applied to trajectory generation and may provide a method for interoperability between trajectory generators. It also supports the request and generation of new types of trajectory profiles not possible with the previous interface to the Trajectory Synthesizer. Other enhancements allow the Trajectory Synthesizer to meet the current and future needs of Air Traffic Management research
Do Appeals to Donor Benefits Raise More Money than Appeals to Recipient Benefits? Evidence from a Natural Field Experiment with Pick.Click.Give.
We partnered with Alaska’s Pick.Click.Give. Charitable Contributions Program to implement a statewide natural field experiment with 540,000 Alaskans designed to explore whether targeted appeals emphasizing donor benefits through warm glow impact donations. Results highlight the relative import of appeals to self. Individuals who received such an appeal were 4.5 percent more likely to give and gave 20 percent more than counterparts in the control group. Yet, a message that instead appealed to recipient benefits had no effect on average donations relative to the control group. We also find evidence of long-run effects of warm glow appeals in the subsequent year

Exchange biased anomalous Hall effect driven by frustration in a magnetic kagome lattice.
Co[Formula: see text]Sn[Formula: see text]S[Formula: see text] is a ferromagnetic Weyl semimetal that has been the subject of intense scientific interest due to its large anomalous Hall effect. We show that the coupling of this material's topological properties to its magnetic texture leads to a strongly exchange biased anomalous Hall effect. We argue that this is likely caused by the coexistence of ferromagnetism and geometric frustration intrinsic to the kagome network of magnetic ions, giving rise to spin-glass behavior and an exchange bias
