Would dogs copy irrelevant actions from their human caregiver?

Companion dogs learn easily from humans, including human behavior, human communication, and some aspects of the human-made environment. They benefit from having the opportunity to learn from humans and are able to spontaneously synchronize their behavior with that of their caregiver. Here, we tested whether pet dogs would show a special form of observational learning, one that has been considered uniquely human. Indeed, humans show overimitation, the faithful copying of causally irrelevant actions, but great apes do not. Because in humans this peculiar form of imitation is strongly motivated by social factors, such as affiliation or conformity, we hypothesized that domesticated and enculturated dogs are more likely than apes are to copy such actions, especially if shown by their affiliated caregiver. Indeed, half of the dogs replicated a causally irrelevant action that was demonstrated by their caregiver, and about the same number did this whether they saw only this action being demonstrated or being demonstrated before or after a causally relevant, functional action. The demonstration of a causally relevant action, one that is immediately followed by access to food, thus does not inhibit the copying of an action that is spatially separated and functionally opaque. Given that the copying frequency in this study was low overall, these results suggest evidence for overimitation in dogs, which might challenge the human uniqueness of this type of social learning.     

Addressing individual difficulties in reading: issues relating to Reading Recovery and Pause,Prompt, Praise

Recently the DfES has issued guidance on ways to address the needs of students who experience difficulties in literacy through Wave Three provision in the National Literacy Strategy ( DfES, 2002 ). This guidance raises the issue of what kind of programmes might be initiated in mainstream schools that will improve what is available generally for pupils who experience difficulties. The original Literacy Taskforce report (1997) named Reading Recovery (RR) as one programme suitable for this purpose. It is not the only programme with 'proven' efficacy, however. This article compares RR and another New Zealand‐based programme, Pause, Prompt, Praise (PPP) with which it has a number of characteristics in common, in order to examine particular issues which are important to ensure that a particular programme can meet individual children's literacy needs and also have the potential for adoption by LEAs and schools in the current national curricular context. These issues are the underpinning rationales, assumptions about the reading process and questions of resources, ownership and control ( Openshaw et al., 2002 ).     

Establishing the critical elements that determine authentic assessment

This study sought to determine the critical elements of an authentic learning activity, design them into an applicable framework and then use this framework to guide the design, development and application of work-relevant assessment. Its purpose was to formulate an effective model of task design and assessment. The first phase of the study identified from the literature critical elements that determined assessment as being authentic, and presented these to practitioners and experts for feedback. In phase two, it codified the elements into a framework that was then applied to the redesign of assessments in an army course. Phase three involved student evaluation of the redesigned assessment activities. This led to further review and revision of elements in phase four. The study outcomes suggest that it is possible, by identifying and codifying individual elements, to determine the ways in which the authenticity of an individual assessment activity might be enhanced. The paper concludes with a literature update on the framework elements that lead to suggestions for further research.     

Heat transfer variations of bicycle helmets

Abstract

Bicycle helmets exhibit complex structures so as to combine impact protection with ventilation. A quantitative experimental measure of the state of the art and variations therein is a first step towards establishing principles of bicycle helmet ventilation. A thermal headform mounted in a climate-regulated wind tunnel was used to study the ventilation efficiency of 24 bicycle helmets at two wind speeds. Flow visualization in a water tunnel with a second headform demonstrated the flow patterns involved. The influence of design details such as channel length and vent placement was studied, as well as the impact of hair. Differences in heat transfer among the helmets of up to 30% (scalp) and 10% (face) were observed, with the nude headform showing the highest values. On occasion, a negative role of some vents for forced convection was demonstrated. A weak correlation was found between the projected vent cross-section and heat transfer variations when changing the head tilt angle. A simple analytical model is introduced that facilitates the understanding of forced convection phenomena. A weak correlation between exposed scalp area and heat transfer was deduced. Adding a wig reduces the heat transfer by approximately a factor of 8 in the scalp region and up to one-third for the rest of the head for a selection of the best ventilated helmets. The results suggest that there is significant optimization potential within the basic helmet structure represented in modern bicycle helmets.     

Examining care navigation: librarian participation in a team-based approach?

Objective

This study investigated responsibilities, skill sets, degrees, and certifications required of health care navigators in order to identify areas of potential overlap with health sciences librarianship.

Method

The authors conducted a content analysis of health care navigator position announcements and developed and assigned forty-eight category terms to represent the sample''s responsibilities and skill sets.

Results

Coordination of patient care and a bachelor''s degree were the most common responsibility and degree requirements, respectively. Results also suggest that managing and providing health information resources is an area of overlap between health care navigators and health sciences librarians, and that librarians are well suited to serve on navigation teams.

Conclusion

Such overlap may provide an avenue for collaboration between navigators and health sciences librarians.

Undergraduate Student Participation in an Evaluation of a Police Program: A High-Impact Practice

High-impact educational practices are increasingly being recognized as powerful teaching strategies that can positively impact both student and faculty experiences in the classroom. Student persistence in college is correlated to campus integration, and one way this can be successfully facilitated is through student–faculty research partnerships. This paper documents the process of one faculty research team integrating four undergraduate students into an ongoing research project, for which students received course credit. There were many benefits of this collaboration to both student and faculty participants, but there were also many opportunities to better streamline the project and to potentially create an institutional template for replication of this process so that other faculty members can learn from this experience and more easily successfully integrate students into their own research.
