We study the incentives that museums face in determining how much resources to invest in the protection of their artwork from theft. We present and analyze a game-theoretic model of art heists that accounts for the strategic interactions between museums’ and art thieves’ decisions and that incorporates several key features of the black market for stolen art. We find that the equilibrium level of security museums choose need not be monotonic in the true market value or the black market value of artwork, i.e., increasing the value of an art piece—whether it is the true market value or the black market value—does not necessarily lead museums to invest more in protecting their artwork. The effects of parameter changes in the model that reflect a shift of public policy depend critically on what type of policy change is considered. For instance, an increase in the penalty imposed for committing art theft cannot raise the amount of theft in equilibrium and could in fact lead museums to increase their level of security. On the other hand, investing more resources on law enforcement agencies so that they are better able to solve art crimes can actually increase the amount of theft in equilibrium by causing museums to spend less on security. 相似文献

The purpose of the present research was to test the applicability of the Dualistic Model of Passion (Vallerand et al., 2003) to being a sport (football) fan. Three studies provided support for this dualistic conceptualization of passion. Study 1 showed that harmonious passion was positively associated with adaptive behaviours (e.g. celebrate the team's victory), whereas obsessive passion was positively associated with maladaptive behaviours (e.g. risking losing one's job to go to a game). Study 2 used a short Passion Scale and showed that harmonious passion was positively related to the positive affective life of fans during the 2006 FIFA World Cup, psychological health (self-esteem and life satisfaction), and public displays of adaptive behaviours (e.g. celebrate the team's victory into the streets), whereas obsessive passion was predictive of maladaptive affective life (e.g. hating opposing teams' fans) and behaviours (e.g. mocking opposing teams' fans). Finally, Study 3 examined the role of obsessive passion as a predictor of partner's conflict that in turn undermined partner's relationship satisfaction. Overall, the present results provided support for the Dualistic Model of Passion. The conceptual and applied implications of the findings are discussed. 相似文献

Conclusion Publishers may wish to ignore disabilities legislation since it doesn’t apply directly to them, but their customers will not be able ignore the new laws when making purchasing decisions. Thus, as a practical
matter each publisher must develop a game plan for how it will position itself to remain competitive in a marketplace where
the timely availability of their print works in digital formats is becoming a Sine qua non on purchasing checklists.
How individual publishers choose to tackle the new challenges will be determined by a number of variables including the type
of content they publish (humanities, math, science, technical), the production systems they use, the length of their press
runs, the shelf-life of their products, the level of service they are prepared to provide, the risks they are willing to take,
and the dynamics of the markets they serve.
A publisher’s strategy will need frequent review and modification because the variables involved in the accessibility environment
are changing rapidly. New developments are occurring all the time in the legal environment, in production technologies, in
assistive technologies, in distribution technologies, in digital rights management technologies, as well as in file standards.
Solutions will need frequent tuning.
For publishers, accessibility challenges do not stop with providing alternate formats for printed works. Those delivering
their content over private networks via course management systems and over the Internet find that there are other accessibility
requirements and standards to be met. It will behoove publishers to develop and implement informed operating policies and
protocols that assure that onan ongoing basis its products and services meet applicable accessibility requirements and thus
can fully compete in an increasingly demanding marketplace. 相似文献

Externally Contingent and Unstable Self‐Worth as Predictors of Depression in College Women: A 3‐Month Study 下载免费PDF全文
Frederick G. Lopez Brittany Thorne Sydney Schoenecker Kevin Siffert Rebecca Chaliman Erica Castleberry 《Journal of College Counseling》2014,17(2):102-115
Undergraduate women completed measures of externally contingent self‐worth, self‐esteem instability, and depression at the beginning (Time 1) and again 3 months later near the end (Time 2) of an academic semester. Findings indicated that when Time 1 depression scores were controlled for, each Time 1 facet of self‐esteem made significant contributions to Time 2 depression scores. Implications of these findings for the counseling of depressed college students are discussed. 相似文献

It has been shown that 0.15 N hydrogen chloride solution is most suitable for employment as precipitant in the quantitative estimation of silver ion, this procedure reducing adsorption to a minimum.When a more dilute solution of reagent is applied, there is a tendency for a portion of the silver to remain dissolved.When hydrogen chloride possessing a greater concentration than 0.15 N is utilized in this determination, adsorption of Cl? ion, and, to a lesser extent, of Ag+ ion, readily occurs.The data presented here have been obtained by careful application of a recognized method, during the course of which temperature effect, and solubility data were given due consideration. Meticulous nephelometric examination was subsequently accorded each experimental sample prior to the calculation of results. 相似文献
