Reflecting on reflection: scale extension and a comparison of undergraduate business students in the United States and the United Kingdom
In the Peltier, Hay, and Drago (2005) article entitled âThe Reflective Learning Continuum: Reflecting on Reflection,â a reflective learning continuum was conceptualized and tested. This is a follow-up article based on three extensions: (1) determine whether the continuum could be expanded, (2) further validating the continuum using additional schools, and (3) determining whether the continuum could also be applied to undergraduate business education. The findings from a study of U.S. and UK students show that the revised scale is valid and reliable and that U.S. students in the sample universities rated their educational experience higher and were more likely to use reflective thinking practices
An initial intercomparison of atmospheric and oceanic climatology for the ICE-5G and ICE-4G models of LGM paleotopography
This paper investigates the impact of the new ICE-5G paleotopography dataset for Last Glacial Maximum (LGM) conditions on a coupled model simulation of the thermal and dynamical state of the glacial atmosphere and on both land surface and sea surface conditions. The study is based upon coupled climate simulations performed with the oceanâatmosphereâsea ice model of intermediate-complexity Climate de Bilt-coupled large-scale iceâocean (ECBilt-Clio) model. Four simulations focusing on the Last Glacial Maximum [21 000 calendar years before present (BP)] have been analyzed: a first simulation (LGM-4G) that employed the original ICE-4G ice sheet topography and albedo, and a second simulation (LGM-5G) that employed the newly constructed ice sheet topography, denoted ICE-5G, and its respective albedo. Intercomparison of the results obtained in these experiments demonstrates that the LGM-5G simulation delivers significantly enhanced cooling over Canada compared to the LGM-4G simulation whereas positive temperature anomalies are simulated over southern North America and the northern Atlantic. Moreover, introduction of the ICE-5G topography is shown to lead to a deceleration of the subtropical westerlies and to the development of an intensified ridge over North America, which has a profound effect upon the hydrological cycle. Additionally, two flat ice sheet experiments were carried out to investigate the impact of the ice sheet albedo on global climate. By comparing these experiments with the full LGM simulations, it becomes evident that the climate anomalies between LGM-5G and LGM-4G are mainly driven by changes of the earthâs topography

In the past decade, researchers have made new forays into understanding educational leadership and the connections between leadership practices and outcomes for students. While evidence-based leadership practices at the building and district level are critical to the success of students in general and special education settings as a whole, the need for effective leadership in special education as a unique discipline within the field has also received significant attention over the past decade. Another area of special education practice that has received significant attention over the past decade is transition service delivery for secondary students with intellectual disabilities. The purpose of this dissertation is to explore the intersection of special education leadership priorities and effective transition service delivery for high school students with severe disabilities. Specifically, this study addresses the research question, âWhat skills and knowledge do special education leaders prioritize when leading transition programs for secondary students with severe disabilities?â Using a demographic questionnaire, a Q-sort and follow up questions, this dissertation gathered information from 17 special education leaders in Inclusive Concurrent Enrollment Advisory Groups and 17 special education leaders who have not participated in Inclusive Concurrent Enrollment to identify differences in each groupâs priorities for educational leadership activities. This study of the nexus between specific leadership activities and secondary transition services for students with severe disabilities has the potential to address long-standing barriers to college access and success for this student population and serve as a guide for professional practice and policy decisions
Secular sea level change in the Russian sector of the Arctic Ocean

The definitive version was published in Journal of Geophysical Research 109 (2004): C03042, doi:10.1029/2003JC002007.Sea level is a natural integral indicator of climate variability. It reflects changes in practically all dynamic and thermodynamic processes of terrestrial, oceanic, atmospheric, and cryospheric origin. The use of estimates of sea level rise as an indicator of climate change therefore incurs the difficulty that the inferred sea level change is the net result of many individual effects of environmental forcing. Since some of these effects may offset others, the cause of the sea level response to climate change remains somewhat uncertain. This paper is focused on an attempt to provide first-order answers to two questions, namely, what is the rate of sea level change in the Arctic Ocean, and furthermore, what is the role of each of the individual contributing factors to observed Arctic Ocean sea level change? In seeking answers to these questions we have discovered that during the period 1954â1989 the observed sea level over the Russian sector of the Arctic Ocean is rising at a rate of approximately 0.123 cm yrâ1 and that after correction for the process of glacial isostatic adjustment this rate is approximately 0.185 cm yrâ1. There are two major causes of this rise. The first is associated with the steric effect of ocean expansion. This effect is responsible for a contribution of approximately 0.064 cm yrâ1 to the total rate of rise (35%). The second most important factor is related to the ongoing decrease of sea level atmospheric pressure over the Arctic Ocean, which contributes 0.056 cm yrâ1, or approximately 30% of the net positive sea level trend. A third contribution to the sea level increase involves wind action and the increase of cyclonic winds over the Arctic Ocean, which leads to sea level rise at a rate of 0.018 cm yrâ1 or approximately 10% of the total. The combined effect of the sea level rise due to an increase of river runoff and the sea level fall due to a negative trend in precipitation minus evaporation over the ocean is close to 0. For the Russian sector of the Arctic Ocean it therefore appears that approximately 25% of the trend of 0.185 cm yrâ1, a contribution of 0.048 cm yrâ1, may be due to the effect of increasing Arctic Ocean mass.This material is based upon

The Role of Families in Youth Sport Programming in a Canadian Aboriginal Reserve
Background: There has been a recent push in the sport psychology literature for sport participants to be approached based on their cultural backgrounds. However, there are few examples where a cultural approach is considered, such as a culturally reflexive version of participatory action research (PAR). In the current study, the role of family is considered in relation to the sport engagement of Canadian Aboriginal youth. Methods: Mainstream researchers teamed with co-researchers from the Wikwemikong Unceded Indian Reserve for 5 years. Community meetings and talking circles were employed as culturally sensitive data collection techniques to uncover how to encourage youth participation in Wikwemikongâs sport programs. The overarching methodology for the project is PAR. Results: Themes and subthemes were determined by community consensus with terms indigenous (ie, culturally relevant) among the local Aboriginal culture. Family was considered important for youth involvement in Aboriginal community sport programs. Parents were expected to support their children by managing schedules and priorities, providing transportation, financial support, encouragement, and being committed to the childâs activity. Aunts, uncles, cousins, siblings, grandparents, and the family as a whole were seen as sharing the responsibility to retain youth in sport through collateral support (ie, when gaps in parental support arose). Conclusions: Suggestions are proposed regarding how families in Aboriginal communities can collaborate to facilitate sport and physical activity among their youth. Further suggestions are proposed for researchers engaging in culturally reflexive research with participants and coresearchers from oppressed cultures
The Differential Reaction of Strains Within a Variety of Wheat to Physiologic Forms of Puccinia graminis tritici
Black stem rust of wheat (Puccinia graminis tritici (Pers.) Erikss. & Henn.), which occurs in Nebraska and thruout most of the wheat producing regions of the world, is of a composite nature, in that it consists of a number of physiologic forms which can be determined by their action on different varieties of Triticum species, as shown by Stakman and Levine. The ordinary commercial variety of wheat may likewise be regarded as a mixture, in that it consists of numerous strains, which differ in some more or less important characteristics, as has been frequently indicated in the literature concerning wheat improvement. The object of this investigation has been to analyze such a commercial mass-variety of wheat from the standpoint of the differential reaction of its component strains to a number of the physiologic forms of Puccinia graminis tritici found in Nebraska. The applied significance of such a study would be the discovery of productive wheat strains in a commercial variety, which are resistant to a relatively large number of prevalent physiologic forms, thereby reducing the likelihood of severe rust damage from season to season, as it has been determined (unpublished data) from epidemiological studies in Nebraska that the physiologic forms which occur in the field may vary in number, identity, distribution, and intensity in different seasons
Scale invariant correlations and the distribution of prime numbers
Negative correlations in the distribution of prime numbers are found to
display a scale invariance. This occurs in conjunction with a nonstationary
behavior. We compare the prime number series to a type of fractional Brownian
motion which incorporates both the scale invariance and the nonstationary
behavior. Interesting discrepancies remain. The scale invariance also appears
to imply the Riemann hypothesis and we study the use of the former as a test of
the latter.Comment: 13 pages, 8 figures, version to appear in J. Phys.
Test in a beam of large-area Micromegas chambers for sampling calorimetry
Application of Micromegas for sampling calorimetry puts specific constraints
on the design and performance of this gaseous detector. In particular, uniform
and linear response, low noise and stability against high ionisation density
deposits are prerequisites to achieving good energy resolution. A
Micromegas-based hadronic calorimeter was proposed for an application at a
future linear collider experiment and three technologically advanced prototypes
of 11 m were constructed. Their merits relative to the
above-mentioned criteria are discussed on the basis of measurements performed
at the CERN SPS test-beam facility
Trace Spaces: an Efficient New Technique for State-Space Reduction
State-space reduction techniques, used primarily in model-checkers, all rely
on the idea that some actions are independent, hence could be taken in any
(respective) order while put in parallel, without changing the semantics. It is
thus not necessary to consider all execution paths in the interleaving
semantics of a concurrent program, but rather some equivalence classes. The
purpose of this paper is to describe a new algorithm to compute such
equivalence classes, and a representative per class, which is based on ideas
originating in algebraic topology. We introduce a geometric semantics of
concurrent languages, where programs are interpreted as directed topological
spaces, and study its properties in order to devise an algorithm for computing
dihomotopy classes of execution paths. In particular, our algorithm is able to
compute a control-flow graph for concurrent programs, possibly containing
loops, which is "as reduced as possible" in the sense that it generates traces
modulo equivalence. A preliminary implementation was achieved, showing
promising results towards efficient methods to analyze concurrent programs,
with very promising results compared to partial-order reduction techniques
