Description of Goussia kuehae n. sp. (Apicomplexa: Eimeriidae) infecting the Asian seabass, Lates calcarifer (Bloch)(Perciformes: Latidae), cultured in Malaysian fish farms
Culturing fishes in marine cages is a rapidly
developing area of marine aquaculture. The Asian
seabass Lates calcarifer (Bloch) is a fast growing good
quality fish that is readily cultured in intensive systems
in the South Asian region and in Malaysia in
particular. Although several papers have been published
to date on viral, bacterial, parasitic and fungal
organisms causing diseases in the Asian seabass, the
occurrence of a coccidian infection in this species has
only recently been recorded. We collected sporulated
and unsporulated oo¨cysts of a new species of Goussia
Labbe´, 1986, from the mucus covering the epithelium
of the intestine of L. calcarifer. This paper provides a
description of Goussia kuehae n. sp. Sporulated
oo¨cysts of this species are ellipsoidal, 37–40 lm in
length and 28–30 lm in width. The ellipsoidal sporocysts
are relatively small, 15.2–17 9 5.7–8 lm, and
located loosely in the oo¨cyst. There are residual bodies
both in the oo¨cysts and the sporocysts. Goussia kuehae
n. sp. differs from all known species of Goussia in the large size of the oo¨cysts and in having two types of
oo¨cyst residuum
Towards a framework for attention cueing in instructional animations: Guidelines for research and design
This paper examines the transferability of successful cueing approaches from text and static visualization research to animations. Theories of visual attention and learning as
well as empirical evidence for the instructional effectiveness of attention cueing are reviewed and, based on Mayer’s theory of multimedia learning, a framework was developed for classifying three functions for cueing: (1) selection—cues guide attention
to specific locations, (2) organization—cues emphasize structure, and (3) integration—cues explicate relations between and within elements. The framework was used to structure the
discussion of studies on cueing in animations. It is concluded that attentional cues may facilitate the selection of information in animations and sometimes improve learning, whereas organizational and relational cueing requires more consideration on how to enhance understanding. Consequently, it is suggested to develop cues that work in animations rather than borrowing effective cues from static representations. Guidelines for future research on attention cueing in animations are presented

Demonizing in Children’s Television Cartoons and Disney Animated Films
The purpose of this study was to assess the prevalence of demonizing in the two major media that young children use (television and movies). Two content analyses were conducted using the animated feature films (n = 34) of the Walt Disney Company and after-school cartoons (n = 41). Each was coded for the modeling of the use of "evil" words when referring to a person, e.g., monster, devil, demon, wicked. Seventy-four percent of the Disney films contained "evil" references, with an average of 5.6 references per film. Forty-four percent of the after-school cartoons contained "evil" references, with an average of one per cartoon. The results are discussed within the context of children's repeated exposure to popular animated movies and cartoons and their learning to demonize people who engage in perceived "bad" behaviors. © Springer Science+Business Media, Inc. 2006
