Classification and retrieval on macroinvertebrate image databases
2011
Aquatic ecosystems are continuously threatened by a growing number of human induced changes. Macroinvertebrate biomonitoring is particularly efficient in pinpointing the cause-effect structure between slow and subtle changes and their detrimental consequences in aquatic ecosystems. The greatest obstacle to implementing efficient biomonitoring is currently the cost-intensive human expert taxonomic identification of samples. While there is evidence that automated recognition techniques can match human taxa identification accuracy at greatly reduced costs, so far the development of automated identification techniques for aquatic organisms has been minimal. In this paper, we focus on advancing …
Cognitive skills, self-beliefs and task interest in children with low reading and/or arithmetic fluency
2022
This study examined the identifiability and early cognitive and motivational markers of low reading and arithmetic fluency. Comparisons of these characteristics between Finnish third graders (n = 197) with low fluency in reading, arithmetic, or both revealed, first, that the majority of third graders with low arithmetic fluency showed low arithmetic skills already at first-grade spring, whereas children with low reading fluency were identified from the second-grade fall onward. Second, all groups with low fluency showed low rapid automatized naming and counting skills across the primary school years, while in other cognitive skills these groups showed different patterns. Third, all groups w…
