In this paper, we construct a general probabilistic spatial theory of elections and examine sufficient conditions for equilibrium in two-candidate contests with expected vote-maximizing candidates. Given strict concavity of the candidate objective function, a unique equilibrium exists and the candidates adopt the same set of policy positions. Prospective uncertainty, reduced policy salience, degree of concavity of voter utility functions, some degree of centrality in the feasible set of policy locations, and restrictions on the dimensionality of the policy space are all stabilizing factors in two-candidate elections.
3. CITIZEN. We have been called so of many, not that our heads are some brown, some black, some auburn, some bald, but that our wits are so diversely colored. And truly I think if all our wits were to issue out of one skill, they would fly east, west, north, south, and their consent of one direct way should be at once to all points o' the compass.

Research shows that environmental hazards are disproportionately located in poor and minority communities, but most of these
studies examine the association between community demographics and the presence (and/or frequency) of one type of environmental
hazard at a time. The current study extends the prior research by examining the concentration of multiple forms of environmental
hazards and structural disadvantage of school areas. School area structural disadvantage is associated with an increase in
the number of environmental hazards, but the magnitude of the association is relatively small. Implications for future research
are discussed.

This paper presents the results of an exploratory study designed to identify and determine the effects of social and economic
factors on Mississippians’ attitudes toward prison expansion strategies. Data were obtained from a statewide survey, utilizing
a random digit dialing telephone sampling procedure. The study sample consists of 606 respondents. Favorable attitudes toward
correctional facilities were hypothesized to be explained by fear of crime, presence of an existing facility, perceived economic
impact of prisons, gender, race, age, and income. The results of the regression analysis revealed that the presence of an
existing prison facility, perceived economic benefits, race, and education were significant predictors of attitudes toward
prison expansion strategies among Mississippians. Possible explanations for the findings and directions for future research
are discussed.

Advances in robotic handwriting technology create new challenges for forensic document examiners. In the past, devices such as the autopen were used to replicate signatures of government officials and corporate companies. In today's technology, companies such as Bond utilize robots to create written documents, which mimic natural patterns of handwriting. They generate customizable written samples by simulating pen movements and letter formations. Four forensic document examiners were given various reproduced questioned documents and utilized a modified ACE‐V (analysis, comparison, evaluation, verification) methodology to determine their genuineness. Examiners were able to make a distinction between the human writing samples and the skilled robotic equivalents. Several distinct features that are not seen in natural handwriting, such as even pen pressure and the superimposition of letterforms were observed in the robotic samples. Careful examination of identifying features of the Bond produced documents resulted in an opinion of nongenuineness. 相似文献
