Article
Shrimp farming in Southeast Asia is often touted as a globalisation success story. The region emerged as a key area for farmed shrimp production in the 1990s, and it remains a leading producer of shrimp for export to international markets to this day. This achievement has not, however, been without cost. Small-scale shrimp farmers in Southeast Asia...

Article
Full-text available
Researchers have long aimed to quantify environmental attitudes, subsequently incorporating them into more comprehensive models of values, attitudes, and behaviors. However, many metrics, notably the New Environmental Paradigm scale, conflate a situated, incomplete set of environmental attitudes with pro-environmental worldviews generally. Further,...
Article
Full-text available
Environmental organizations have become increasingly interested in identifying groups in the general population that understand scientific issues in an internally cohesive way. However segmenting these groups empirically is contingent on employing metrics with high levels of reliability and validity, and many existing metrics are dated or make assu...

This article describes three exploratory investigations of dimensions influencing scuba diver perceptions of crowding in underwater settings. Five focus groups of five to eight divers each suggested that number, proximity, and clustering of divers were important crowding dimensions. A multiple sort procedure with 60 other divers revealed that numbe...
Article
Full-text available
Acceptance of tourism and recreation management strategies depends on situational factors including social, resource, and facility impacts. If an area has adequate facilities, little crowding, and minimal environmental impacts, modifying existing management may be opposed. If an area is damaged and overcrowded, actions such as limiting access may b...
