(Re)viewing the landscape inside and outside the box : providing effective support for early childhood student teachers

This paper presents key findings from a study that investigated how early childhood student teachers perceived the support, guidance and mentoring facilities that were available to them and aspects of their courses. The study was conducted by lecturers who were delivering the three year Bachelor of Teaching (ECE) degree to a multicultural student cohort in a New Zealand polytechnic. A multi-method approach was taken and involved practitioner action research, questionnaires and interviews with students. The findings showed that whilst first year students found large group guidance useful, second and third year students preferred small group and individual support. Being able to email lecturers, particularly during practicum placements, was important for students. During practicum placements Associate Teachers who were culturally competent communicators and fully informed about students’ coursework were important for student success. Practicums where students experienced open communication were included as part of the teaching team and felt well-informed about the philosophy and practices of the centre were found to increase their confidence and competence. However, students expressed concern that in some placements, they felt under informed or isolated. Hence, this paper argues that lecturers and Associate Teachers should be proactive about initiating communication with students and optimize opportunities for individual mentoring through questions and guided reflection.

Measuring walking within and outside the neighborhood in Chinese elders : reliability and validity

Background : Walking is a preferred, prevalent and recommended activity for aging populations and is influenced by the neighborhood built environment. To study this influence it is necessary to differentiate whether walking occurs within or outside of the neighborhood. The Neighborhood Physical Activity Questionnaire (NPAQ) collects information on setting-specific physical activity, including walking, inside and outside one's neighborhood. While the NPAQ has shown to be a reliable measure in adults, its reliability in older adults is unknown. Additionally its validity and the influence of type of neighborhood on reliability and validity have yet to be explored. Methods : The NPAQ walking component was adapted for Chinese speaking elders (NWQ-CS). Ninety-six Chinese elders, stratified by social economic status and neighborhood walkability, wore an accelerometer and completed a log of walks for 7 days. Following the collection of valid data the NWQ-CS was interviewer-administered. Fourteen to 20 days (average of 17 days) later the NWQ-CS was re-administered. Test-retest reliability and validity of the NWQ-CS were assessed. Results : Reliability and validity estimates did not differ with type of neighborhood. NWQ-CS measures of walking showed moderate to excellent reliability. Reliability was generally higher for estimates of weekly frequency than minutes of walking. Total weekly minutes of walking were moderately related to all accelerometry measures. Moderate-to-strong associations were found between the NWQ-CS and log-of-walks variables. The NWQ-CS yielded statistically significantly lower mean values of total walking, weekly minutes of walking for transportation and weekly frequency of walking for transportation outside the neighborhood than the log-of-walks. Conclusions : The NWQ-CS showed measurement invariance across types of neighborhoods. It is a valid measure of walking for recreation and frequency of walking for transport. However, it may systematically underestimate the duration of walking for transport in samples that engage in high levels of this type of walking.

On the V-type asteroids outside the Vesta family - II. Is (21238) 1995 WV7 a fragment of the long-lost basaltic crust of (15) Eunomia?

Context. The V-type asteroids are associated with basaltic composition. Apart from ( 1459) Magnya, an asteroid that is clearly dynamically and mineralogically unconnected to the Vesta family, all currently known V-type asteroids are either members of the Vesta family, or are hypothesized to be former members of the dynamical family that migrated to their current orbital positions. The recent identification of ( 21238) 1995 WV7 as a V-type asteroid introduces the possibility that a second basaltic asteroid not connected with the Vesta family exists. This asteroid is on the opposite side of the 3: 1 mean motion resonance with respect to Vesta, and it would be very unlikely that a member of the Vesta family of its size (D > 5km) migrating via either the Yarkovsky effect or repeated close encounters with Vesta survived the passage through such a resonance.Aims. In this work we investigate the possibility that ( 21238) 1995 WV7 originated as a fragment of the parent body of the Eunomia family and then migrated via the interplay of the Yarkovsky effect and some powerful nonlinear secular resonances, such as the (s - s(6)) - ( g(5) - g(6)). If (15) Eunomia is, as claimed, a differentiated object whose originally pyroxene-enriched crust layer was lost in a collision that either created the Eunomia family or preceded its formation, can (21238) be a fragment of its long-lost basaltic crust that migrated to the current position?Methods. We mapped the phase space around (21238) and determined which of the nonlinear secular resonances that we identified are stronger and more capable of having caused the current difference in proper i between (21238) and members of the Eunomia family. We simulated the Yarkovsky effect by using the SWIFT-RMVSY integrator.Results. Our results suggest that it is possible to migrate from the Eunomia dynamical family to the current orbital location of ( 21238) via the interplay of the Yarkovsky effect and the (s - s6) - (g5 - g6) nonlinear secular resonance, on time-scales of at least 2.6 Gyr.Conclusions. (15) Eunomia might be the third currently known parent body for V-type asteroids.

A method for rearing immature stages of Apis melifera outside the colony (Hymenoptera: Apidae)

The objective this work is to define an effective method for following the development of immatures of Apis mellifera from metamorphosis to the emergence of the adult, under conditions allowing the application of diverse treatments. The results showed the best method to be when broods with 5th instar larvae and prepupae were maintained in incubators with the temperature and humidity controlled at 34°C and 65 to 70% respectively.

STATUS OF BROMETHALIN OUTSIDE THE UNITED STATES

ABSTRACT: Bromethalin has been extensively researched over the past decade in the United States, Switzerland, England, Denmark, and France. United States EPA registrations were received in 1982 and commercial pelleted formulations containing 0.01% bromethalin were developed and introduced in the USA by Ralston Purina (ASSAULT1*) in 1985 and Velsicol (VENGEANCE1*) in 1986. Ciba-Geigy is currently developing new formulations under the tradename DORATIDR for use outside the United States. Bromethalin acute toxicity and 14-day subchronic studies are reviewed and data from recently completed 90-day subchronic studies required for registration outside the US are presented. Pharmacodynamic studies have shown that bromethalin acts as an uncoupler of oxidative phosphorylation, thus interrupting the vital production of ATP necessary to maintain essential metabolic functions. Laboratory and field trial data are presented from Switzerland, France, England, and Denmark that indicate the effectiveness of new bromethalin formulations against anticoagulant resistant and susceptible rodents. A comparative rodenticide pen testing system is described from which test results confirm bromethalin's quick action and feed consumption efficiency when compared to second-generation anticoagulants.
