Implementing non-traditional assessment strategies in teacher preparation: Opportunities and challenges
Assessment and grading in higher education have traditionally focused on “A” through “F”, or point-based alpha-numeric letter grades and subjective, independent grading systems. Despite the ubiquity of this system, there are no universal guidelines on how to assess student learning on that scale. What can be problematic about “the way things have always been” is that students are frequently de-humanized; higher education faculty often focus on compliance and authoritarian teaching rather than engaging in the learning process alongside the students. In contrast, some faculty members have explored non-traditional assessment practices in their coursework to enhance the learning process and improve individualized student support. This article offers strategies for implementing non-traditional assessments, specifically mediated office hours, mastery learning, and ungrading strategies are addressed
Social capital and political participation: understanding the dynamics of young people's political disengagement in contemporary Britain
Only 37 per cent of young people voted at the 2005 British General Election, seemingly confirming the oft-cited view that this generation is becoming increasingly disconnected from the political process. Results from a nationwide survey however, indicate that their withdrawal from formal politics is more a result of their scepticism of the way the political system operates, than apathy. Furthermore, they are diverse in their political (dis)engagement. Results from an examination of the relative effects of socio-economic location and social capital are inconclusive, although the data indicate that government social policy aimed at mobilising social capital and addressing socio-economic issues may increase civic engagement

Precision Doppler Shift Measurements with a Frequency Comb Calibrated Laser Heterodyne Radiometer
We report precision atmospheric spectroscopy of using a laser
heterodyne radiometer (LHR) calibrated with an optical frequency comb. Using
the comb-calibrated LHR, we record spectra of atmospheric near 1572.33
nm with a spectral resolution of 200 MHz using sunlight as a light source. The
measured spectra exhibit frequency shifts by approximately 11 MHz over
the course of the five-hour measurement, and we show that these shifts are
caused by Doppler effects due to wind along the spectrometer line of sight. The
measured frequency shifts are in excellent agreement with an atmospheric model,
and we show that our measurements track the wind-induced Doppler shifts with a
relative frequency precision of 100 kHz (15 cm/s), equivalent to a fractional
precision of a few parts in . These results demonstrate that
frequency-comb-calibrated LHR enables precision velocimetry that can be of use
in applications ranging from climate science to astronomy.Comment: 4 pages, 3 figure

Effects of overtopping on growth of white spruce in Alaska
Early establishment of competing vegetation often presents an obstacle to the success of planted white spruce (Picea glauca (Moench) Voss) seedlings. We followed growth and development of white spruce and associated vegetation for up to 17 years in Alaska's boreal forests to quantify roles of overtopping plant cover in suppressing conifers. The three study areas represented a range of site conditions of varying productivity and species of competing cover, different site preparation and release treatments, and different bare-root and container white spruce stock types. Herbaceous overtopping peaked early after planting and decreased as white spruce were able to outgrow competitors. Overtopping by shrubs and hardwoods, especially aspen (Populus tremuloides Michx.) and resin birch (Betula neoalaskana Sarg.) peaked somewhat later than herbaceous overtopping and decreased over time for most sites and treatments. In a model that combined all sites, vegetation management treatments, and years, overtopping and previous year's volume explained approximately 85% of the variation in volume growth. Increasing the size of planting stock helped reduce overtopping, hence suppression, even in treatments dominated by hardwood species. Results suggested that control of overtopping was essential for maximum growth and long-term or increasing levels of overtopping severely suppressed white spruce seedling growth.Keywords: Douglas-fir,
