THE HISTORY OF PEACEKEEPING OFFERS IMPORTANT LESSONS FOR ESTABLISHING "ZONES OF PEACE." PEACEKEEPING OPERATIONS HAVE RELIED ON DEMILITARIZED ZONES AND SAFETY ZONES, TWO FOUNDATIONS FOR CREATING MORE COMPREHENSIVE ZONES OF PEACE THAT MOVE BEYOND CEASE-FIRE ARRANGEMENTS TOWARD PEACE-BUILDING ACTIVITIES. THIS ARTICLE EXAMINES THE DEVELOPMENT OF ONE SUCH PEACE ZONE BY CONSIDERING THE UN PEACEKEEPING MISSION IN THE CONGO IN THE EARLY 1960S. IT ARGUES THAT ITS LESSONS MAY HELP BETTER PROVIDE FUTURE ZONES OF PEACE.

Two experiments suggest that providing some instruction on new videotext technologies does not necessarily lead to a more positive initial experience or positive program evaluation, except where a system is complex and the user task difficult. Yet the experiments do suggest that as systems become more complex, personalized instruction on use may pay dividends in a number of ways.

A review of existing research shows some evidence that persons dependent on television news for public affairs information are more likely to have negative attitudes toward government and to be less well informed about that government than persons dependent on newspapers Such a relationship between dependency and evaluations and knowledge of government was replicated here, though only where local government was concerned The meaning of the dependency concept is explored and empirical evidence is offered that dependency is distinct from simple exposure to the media

The determination of rates and stocks of carbon storage in salt marshes, as well as their protection, require that we know where they and their boundaries are. Marsh boundaries are conventionally mapped through recognition of plant communities using aerial photography or satellite imagery. We examined the possibility of substituting the use of 1 m resolution LiDAR-derived digital elevation models (DEMs) and tidal elevations to establish salt marsh upper boundaries on the New Brunswick coasts of the Gulf of St. Lawrence and the Bay of Fundy, testing this method at tidal ranges from ≤2 to ≥4 m. LiDAR-mapped marsh boundaries were verified with high spatial resolution satellite imagery and a subset through field mapping of the upland marsh edge based upon vegetation and soil characteristics, recording the edge location and elevation with a Differential Geographic Positioning System. The results show that the use of high-resolution LiDAR and tidal elevation data can successfully map the upper boundary of salt marshes without the need to first map plant species. The marsh map area resulting from our mapping was ~30% lower than that in the province's aerial-photograph-based maps. However, the difference was not primarily due to the location of the upper marsh boundaries but more so because of the exclusion of mudflats and large creeks (features that are not valued as carbon sinks) using the LiDAR method that are often mapped as marsh areas in the provincial maps. Despite some minor limitations, the development of DEMs derived from LiDAR can be applied to update and correct existing salt marsh maps along extensive sections of coastlines in less time than required to manually trace from imagery. This is vital information for governments and NGOs seeking to conserve these environments, as accurate mapping of the location and area of these ecosystems is a necessary basis for conservation prioritization indices.

Technologies used for media presentation are becoming more integrated with overall work processes in media organizations. This study seeks to determine how important skill with presentation technology is as a predictor of job-finding success for graduates of journalism and mass communication. Findings show that level of technological skill is a significant predictor when controlling for traditional determinants such as grade point average, internship experience, college media activity, and curriculum sequence. Skill with presentation software for the Web is the strongest predictor of success for graduates seeking work in online publishing, which suggests that the more specific the technology skill, the better it predicts success.

This paper examines whether gender, race, and ethnicity are associated with employment in the journalism and mass communication labor market and—if discrepancies in employment exist—what explanations might he offered for them. The data show strong evidence that race and ethnicity are associated with lower levels of employment among journalism and mass communication graduates. These discrepancies in success in the job market are explainable in highly specified situations by factors normally associated with hiring, such as type of training, type of institution offering the training, or qualifications such as internship experience and level of performance in the classroom.
