The taming of the duel: masculinity, honour and ritual violence in London, 1660–1800

Over the course of the ‘long’ eighteenth century the nature and significance of duels fought in the London area changed dramatically. Pistols replaced swords, seconds took on a new role as mediators, and new conventions reduced the violence. Consequently, injuries and fatalities decreased significantly. The purpose of fighting duels also shifted from the defeat of one's antagonist to a demonstration of courage. Although duels continued to occur, growing opposition meant that the audience of people who supported duelling became increasingly limited and duels took place in places far from public view. At the same time, both the press and the courts provided alternative strategies for defending reputations. These changes cannot be attributed to technological developments, official attempts to prevent duelling, or the embourgeoisement of the duel. Rather, they resulted from a series of interlinked cultural changes, including an increasing intolerance of violence, new internalized understandings of elite honour, and the adoption of ‘polite’ and sentimental norms governing masculine conduct. These eighteenth-century changes shed new light on the reasons for the final end of duelling in England in 1852

Causal and Metaphysical Necessity

Any property has two sorts of causal features: “forward‐looking” ones, having to do with what its instantiation can contribute to causing, and ldquo;backward‐looking” ones, having to do with how its instantiation can be caused. Such features of a property are essential to it, and properties sharing all of their causal features are identical. Causal necessity is thus a special case of metaphysical necessity. Appeals to imaginability have no more force against this view than they do against the Kripkean view that statements like “Gold is an element” are metaphysically necessary

Can Universities Encourage Students Continued Motivation For Knowledge Sharing And How Can This Help Organizations?

Both practitioners and researchers recognize the increasing importance of knowledge sharing in organizations (Bock, Zmud, Kim, & Lee, 2005; Vera-Muz, Ho, & Chow, 2006). Knowledge sharing influences a firm\u27s knowledge creation, organizational learning, performance achievement, growth, and competitive advantage (Bartol & Srivastava, 2002; Bock & Kim, 2002; Vera-Muz et al., 2006). However, an individual\u27s natural tendency is to hoard knowledge rather than to share knowledge (Davenport, 1997; Ruggles, 1998). So, how can knowledge sharing be encouraged? Extrinsic rewards are believed to effectively motivate desired behaviors (Bartol & Locke, 2000). Under certain environmental conditions, extrinsic rewards are also believed to develop a more sustained motivation, called self-determined motivation, for these behaviors (Deci & Ryan, 1991). These ideas raise the following questions: (a) Do extrinsic rewards motivate students to share knowledge? and (b) How can universities encourage individuals to develop the self-determined motivation to take part in desired behaviors such as knowledge sharing? This study investigates the effect of extrinsic rewards on knowledge sharing in a team setting. It also examines whether universities can facilitate individuals\u27 continued or self-determined motivation to share knowledge using certain environmental conditions. To examine these questions, I perform an experiment with 113 undergraduate students from accounting and management classes who are working on team projects. Results suggest that specifically rewarding knowledge sharing can increase individuals\u27 knowledge-sharing behaviors and, in the right environment, their internalization of the motivation to share knowledge

Constraints on Dark Matter Protohalos in Effective Theories and Neutrinophilic Dark Matter

The mass of primordial dark matter (DM) protohalos remains unknown. However, the missing satellites problem may be an indication that they are quite large. In this paper, we use effective field theory to map constraints on dark matter-SM interactions into limits on the mass of DM protohalos. Given that leptons remain in the thermal bath until late times, we focus on their interactions with DM. To illustrate the method, we use the null results of LEP missing energy searches along with Fermi-LAT searches for DM annihilation in nearby dwarf galaxies, to derive limits on the protohalo mass, $\lesssim (10^{-6}-10^{-1}) M_{\odot}$, with the range depending on the DM mass and the operator. Thus, if DM is to remain thermally coupled until late times and account for the missing satellites, charged lepton interactions are insufficient. This motivates neutrinophilic DM, which can have protohalo masses orders of magnitude larger, with constraints arising from Planck, IceCube and unpublished Super-K data. We show that effective neutrinophilic models offer a solution to the missing satellites problem for sub-GeV DM masses with larger than WIMP-sized annihilation cross sections.Comment: 8 pages, 4 figure
