Professionals' and Families' Perceptions of Family-Centered Practices in Infant-Toddler Services

The purposes of this study were to determine the extent of family-centered practices, professionals' and families' values about the practices, and the extent to which selected characteristics of participants explained variance in the practices. Professionals (N = 198) and families (N = 118) completed two questionnaires. Professionals tended to report more family-centered typical practice than did families, but ideal practices generally did not vary between groups. Agency type and the Setting x Experience interaction predicted professionals' ideal-practice scores and their self-ratings of the frequency of implementing family-centered practices: Home-based services were most predictive of frequent reports of these practices. The frequency with which families reported receiving these practices was predicted by the amount of time the family had been in early intervention: The longer, the more frequently families experienced the practices.     

Writing your first successful grant application to conduct communication research

Advice is offered to help scholars write successful communication grant applications, including practical issues such as learning about opportunities, finding the time to write, planning personnel, budgeting, negotiating internal resources, institutional review boards, and deliverables. Additional tips are offered on theoretically rich research with socially meaningful applied outcomes, counterintuitive mechanisms and outcomes, simplicity, detail orientation, demonstrating expertise in the content area, and demonstrating expertise with the population under investigation. Finally, we mention some important traits for getting through the review process-persistence and low ego-involvement.     

Apprenticeships,Collaboration and Scientific Discovery in Academic Field Studies

Teachers may use apprenticeships and collaboration as instructional strategies that help students to make authentic scientific discoveries as they work as amateur researchers in academic field studies. This concept was examined with 643 students, ages 14–72, who became proficient at field research through cognitive apprenticeships with the Smithsonian Institute, School for Field Studies and Earthwatch. Control student teams worked from single research goals and sets of methods, while experimental teams varied goals, methods, and collaborative activities in Kenya, Costa Rica, Panama, and Ecuador. Results from studies indicate that students who conducted local pilot studies, collaborative symposia, and ongoing, long-term fieldwork generated significantly more data than did control groups. Research reports of the experimental groups were ranked highest by experts, and contributed the most data to international science journals. Data and anecdotal information in this report indicate that structured collaboration in local long-term studies using apprenticeships may increase the potential for students' academic field studies contribution of new information to science.     

Preliminary evidence for color stimuli discrimination in the Asian small-clawed otter (Aonyx cinerea)

Color discrimination ability can be determined through anatomy or perceptual ability. In this study we tested perceptual ability. Three Asian small-clawed otters (Aonyx cinerea), one male and two females, were trained via operant conditioning to discriminate stimuli within a training task. If they passed criteria for this task, they were tested on as many as six delayed matching-to-sample experimental tasks. These experimental tasks involved comparing varying saturations of the colors blue, green, and red against varying shades of gray, as well as against each other. The male reached criterion on five of the experimental tasks, indicating an ability to discriminate the stimuli. One female participated in only two tasks and did not achieve the criteria as set. The second female did not pass the training task, and thus was not experimentally tested. This study overall showed some early evidence that Asian small-clawed otters may have the ability to learn to discriminate different stimuli on the basis of color cues. Sensory studies conducted on two other otter species and the results of this study indicate that color vision may be a common trait across Lutrinae species.

The Network University? Technology,Culture and Organisational Complexity in Contemporary Higher Education

This paper discusses the concept of the network organisation in relation to the technologised university. Drawing upon the early findings of a study that examines the impact of information and communication technologies (ICTs) on both organisational and teaching and learning issues in five Australian universities, the authors discuss the way in which discourses of network technology have become articulated to a range of at times paradoxical agendas within higher education. The introduction of new technologies into organisations tends to be portrayed in either transformative or oppressive terms. The complexity of the university experience foregrounds the important role played by pre‐existing organisational practices and narratives in determining the uses and meanings of ICTs in the organisational setting. These observations place into question the notion that the network organisation is a single coherent entity driven by a particular technological logic. Instead, it suggests that network technologies are socially embedded and therefore highly variable in their expression.     

Performance of good and poor readers at two grade levels on an Auditory Cognitive Style Task

Sixty-four good and poor readers at first and third grades were administered a task measuring cognitive style in the auditory modality. They were also administered the Peabody Picture Vocabulary Test-Revised (PPVT-R) to obtain a measure of IQ. Poor readers committed significantly more errors and exhibited shorter response latencies on the Auditory Cognitive Style Task than did good readers. More importantly, poor readers demonstrated inefficient strategies for successful performance. It was suggested that good reading skills, as well as successful performance on the auditory task, require a certain degree of planfulness and self-monitoring activity on the part of the child which was apparently absent in the poor reader. Furthermore, it was proposed that the cognitive style variable, conceptual tempo, may be better viewed within the framework of the concept of metacognition.
