The U.S. EPA Geographic Information System for Mapping Environmental Releases of Toxic Chemical Release Inventory (TRI) Chemicals

This study characterizes the environmental releases of toxic chemicals of the Toxic Chemical Release Inventory (TRI) in the southeastern United States by using the U.S. Environmental Protection Agency (EPA) Geographic Information System (GIS) to map them. These maps show that the largest quantities of TRI releases in the Southeast are usually near densely populated areas. This GIS mapping approach takes the first steps in defining those areas in the region which may be potential exposure zones and which could be strategic targets for future risk screening efforts in this geographic area.     

Gay men and lesbians' experiences in and expectations for interactions with heterosexuals

We analyzed 97 gay men's and lesbians' experiences with and expectations for interactions with majority group members. Respondents described reactions to previous or imagined future interactions with an unfamiliar heterosexual person who had just become aware that the respondent was lesbian or gay. Results indicated that respondents are more proactive than reactive (in contrast to expectation states theories), that the contact hypothesis can be appropriately applied to this group, even though the formulation of the theory was based upon negative attitudes in the absence of extensive contact, and that they have different reactions for people of different prejudice levels, rather than being globally suspicious, as is predicted by many intergroup theories. Future research should direct more attention to the stigmatized group members' attitudes about and reactions toward the majority group.     

The Relations between Reactivity at 4 Months and Behavioral Inhibition in the Second Year: Replication across Three Independent Samples

This paper examines the predictive relations between two infant temperamental biases assessed at 4 months and inhibited behavior during the first 2 years of life in three independent samples from two research laboratories. Although each sample used slightly different criteria for classifying infants, the results across samples were consistent. Infants of both genders who displayed high levels of motor activity and distress to unfamiliar events were more inhibited at 14 months of age. By 24 months, there were significant sex differences: Boys identified as high reactive were more inhibited than high reactive girls.
