The role of scrrencasts in virtual accounting education

[ES]Despite the rapid growth of new technologies in universities, there is still little empirical evidence on the incidence of certain e-learnings mechanisms on students’ success or failure, particularly among accounting students. According to the cognitive theory of multimedia learning, screencasts are an effective and efficient tool for enhancing students learning, particularly in online accounting education where face-to-face interactions between instructor and students are limited.

Causes of extreme variability of nest density among close and similar beaches of Boavista island (Cape Verde): From 1 to 2000 annual nests per km.

[EN] The 70 km of white sandy beaches of Boa Vista island in Cape Verde harbours one of the largest rookeries of the endangered loggerhead sea turtle, Caretta caretta. From middle June to early October, approximately 2000 to 4000 females lay up to 20000 nests annually. However, female beach selection, nesting success and nest density strongly varies among beaches and spatial patterns of nest abundance and distribution are relatively constant among seasons. The numbers of nesting activities and nests have been recorded along all beaches of the island during four nesting seasons (2007-2010)
