Stoic Moral Psychology: The Implications Of Ventromedial Prefrontal Cortex Damage

In his book, A New Stoicism, Lawrence A. Becker sides with Posidonius, and against Chrysippus and others, on the issue of whether the sage will experience passions. The Posidonian position is that the sage will experience conflicting passions but will, nevertheless, overcome those passions through his or her perfected agency. In opposition, Chrysippus and others assert that the sage will have extirpated all his or her passions as a necessary precondition for achieving sagehood. I will argue that a body of neuroscientific evidence chiefly concerned with the effects of lesions to the ventromedial prefrontal cortex (vmPFC) supports Becker’s assertion that Chrysippus’ call for the extirpation of the passions is neither plausible nor desirable. Recent empirical discoveries support Posidonius’ view of the role of the passions in the virtuous life

Suicide Terrorism and the Weakest Link

In this paper we examine a model of terrorism which focuses on the tradeoffs facing a terrorist organization that has the ability to utilize either or both suicide and conventional terrorism tactics. The terrorist organization’s objective is to successfully attack at least one target. Success for the target government is defined as defending all targets from any and all attacks. In this context, we examine how terrorist entities strategically utilize suicide attacks when other modes of attack are available, and the optimal anti-terrorism measures.conflict, suicide terrorism, weakest link, Colonel Blotto

The Integration of Social Studies and Elementary Science in the Fourth Grade

The purpose of this study is to set up an integrated elementary social studies and science program; informal, flexible, and democratic enough to be in keeping with the modern trends of education, and thus broaden the pupils\u27 understanding so that satisfactory adjustments to their environment may be made. Statement of the Problem 1. How can social studies and elementary science be integrated so as to meet individual needs and promote better human relationship? 2. Should social studies and elementary science be integrated in the curriculum as a means of helping children develop perspectives relative to science as a social force in the modern world? 3. Will integrated social studies and elementary science programs help develop harmonious human relations and reinforce bonds of family life? Data for this study were secured from questionnaires sent to seventy-five teachers of urban, and rural areas to find methods of presenting the social studies and elementary science in the elementary school curriculum. In addition, periodicals, books, and teacher\u27s manuels or bulletins served as guides to seek trends in procedures for teaching social studies and science in the elementary school

Weakest-Link Attacker-Defender Games With Multiple Attack Technologies

In this article, we examine a model of terrorism that focuses on the tradeoffs facing a terrorist organization that has two qualitatively different attack modes at its disposal. The terrorist organization\u27s objective is to successfully attack at least one target. Success for the target government is defined as defending all targets from any and all attacks. In this context, we examine how terrorist entities strategically utilize an efficient but discrete attack technology e.g., suicide attacks when a more conventional mode of attack is available, and the optimal anti-terrorism measures

Free-Sorting of Colors Across Cultures: Are there Universal Grounds for Grouping?

These studies examined naming and free-sorting behavior by informants speaking a wide range of languages, from both industrialized and traditional cultures. Groups of informants, whose color vocabularies varied from 5 to 12 basic terms, were given an unconstrained color grouping task to investigate whether there are systematic differences between cultures in grouping behavior that mirror linguistic differences and, if there are not, what underlying principles might explain any universal tendencies. Despite large differences in color vocabulary, there were substantial similarities in grouping behavior across language groups, and substantial within-language variation across informants. It seems that all informants group stimuli based on some criterion of perceptual similarity, but those with large color vocabularies are more likely to group stimuli in line with their basic color terms. The data are best accounted for by a hybrid system that combines a universal principle of grouping by similarity with culture-specific category salience

Measurements at low energies of the polarization-transfer coefficient Kyy' for the reaction 3H(p,n)3He at 0 degrees

Measurements of the transverse polarization coefficient Kyy' for the reaction 3H(p,n)3He are reported for outgoing neutron energies of 1.94, 5.21, and 5.81 MeV. This reaction is important both as a source of polarized neutrons for nuclear physics experiments, and as a test of theoretical descriptions of the nuclear four-body system. Comparison is made to previous measurements, confirming the 3H(p,n)3He reaction can be used as a polarized neutron source with the polarization known to an accuracy of approximately 5%. Comparison to R-matrix theory suggests that the sign of the 3F3 phase-shift parameter is incorrect. Changing the sign of this parameter dramatically improves the agreement between theory and experiment.Comment: 12 pages, RevTeX, 5 eps figures, submitted to Phys. Rev.
