Exploring adaptations to the modified shuttle walking test
ABSTRACT
Objective: The 10 m modified shuttle walking test
(MSWT) is recommended to determine the functional
capacity in older individuals and for patients entering
cardiac rehabilitation. Participants are required to
negotiate around cones set 1 m from the end markers.
However, consistent comments indicate that for some
individuals manoeuvring around the cones can be
quite difficult. Therefore, the objective of this study
was to explore differences within and between noncardiac
and postmyocardial infarction (MI) males
during MSWT with and without the cones.
Design: Comparative study.
Participants: 20 post-MI (64.8±6.6, range
51–74 years) and 20 non-cardiac male controls
(64.1±5.7, range 52–74 years) participated.
Methods: Participants performed MSWT with and
without cones. Throughout, the participants expired
air, and the heart rate (bpm) (HR) and ratings of
perceived exertion (RPE) were measured. Participant
protocol preference was recorded verbatim.
Results: One-way analysis of variance found no
significant difference in VO2 peak (cones 20.4±5.1 vs nocones
21.9±4.8 ml/kg/min, p=0.197) or distance ambulated
(cones 631.8±132.9 m vs no-cones 662.4±164.1 m,
p=0.371) between protocols or groups. Analysis comparing
lines of regression showed a significant trajectory difference
in VO2 (ml/kg/min) (p<0.01) between protocols with higher
HR (p<0.01) and respiratory exchange ratio (RER, p<0.001)
values during cones. RPEs were higher for post-MIs versus
controls during both protocols (p<0.05). Post-MIs taking
?-blockers produce significantly lower HR values. The ?2
analysis found no significant difference in protocol
preference (no-cones: all n=25, 63%; post-MIs n=13, 65%;
and controls n=12, 60%).
Conclusions: Post-MIs found both protocols
subjectively harder than controls with no significant
difference in the VO2 peak. However, both groups worked
at a lesser percentage of their anaerobic threshold during
no-cones protocol as indicated by lower RER values.
Importantly, for the post-MIs, this would reduce their risk
of functional impairment. Therefore, though more
research is required, indicators at present are more
favourable for the use of the no-cones with post-MIs
Amphibian diversity in Amazonian flooded forests of Peru
Global biodiversity is currently facing the sixth mass extinction, with extinction rates at least 100 times higher than background levels. The Amazon Basin has the richest amphibian fauna in South America, but there remain significant gaps in our knowledge of the drivers of diversity in this region and how amphibian assemblages are responding to environmental change.
Surveys were conducted in the Pacaya-Samiria National Reserve (PSNR) in Amazonian Peru, with a view to (1) comparing assemblage structure on floating meadows and adjacent terrestrial habitats; (2) determining the predictors of diversity in these habitats; and (3) exploring the effects of disturbance and seasonal flooding on diversity measures. Eighty-one species of amphibians have been recorded in these habitats since 1996 representing 11 families and three orders. In 2012-2013 22 anuran species used the floating meadow habitat, of which 10 were floating meadow specialists. These specialists were predominantly hylids which breed on floating meadows all the year round. Floating meadows therefore host an assemblage of species which is different to that found in adjacent terrestrial areas which are subject to seasonal flooding. Floating meadows enhance the amphibian diversity of the region, and rafts of vegetation that break away and disperse frogs downstream may explain the wide distribution of hylids within the Amazon Basin.
Fourteen different reproductive modes were represented within the 54 anuran species observed. The number of reproductive modes present was influenced by localised disturbance and seasonal flooding. Diversity increased in the low water period, with hylids breeding in temporary pools. When the forest is inundated most species disperse away from the flood waters.
Disturbance, habitat change, emerging diseases and climate change would likely lead to changes in species composition and assemblage structure rather than wholescale extinctions. However, further studies are needed to evaluate long-term consequences of synergistic environmental change

A Program of Study for 21st Century Clarinet Techniques Featuring Five New Compositions for Unaccompanied Clarinet
abstract: As clarinet students progress in their studies, there comes a point at which many are assigned to perform contemporary repertoire that is either overplayed due to accessibility and use in pedagogy, or includes difficult extended techniques like microtones, multiphonics, and more. This project identifies a “gap” in unaccompanied clarinet repertoire and seeks to expand this repertoire by outlining a program of study featuring five newly commissioned unaccompanied clarinet solos through which students can learn both traditional and untraditional techniques. Each of the first four works focus on one aspect of clarinet technique—musicality, the altissimo register, microtones, and multiphonics, respectively—and the final work is a culmination of all these techniques. Included in this document is biographical information for each composer, program notes, a brief description, and a performance guide for each piece. Additionally, each work was recorded by the author and included with this document.Dissertation/ThesisPerformer: Olivia Meadows, Composer: Zachary BushPerformer: Olivia Meadows, Composer: Josh GottryPerformer: Olivia Meadows, Composer: Kurt MehlenbacherPerformer: Olivia Meadows, Composer: Spencer BrandPerformer: Olivia Meadows, Composer: Eric P.

Comparison of water velocity profiles through morphologically dissimilar seagrasses measured with a simple and inexpensive current meter
The influence of seagrass morphology on water flow was studied by measuring water velocity profiles through natural seagrass meadows. An array of eight solid-state electronic current meters was used to obtain profiles through meadows of Amphibolis griffithii (Cymodoceaceae), a seagrass which possesses a profusely-branched erect stem with terminal leaf clusters, and two strap-like seagrasses, Posidonia australis and P. sinuosa (Posidoniaceae). Significant differences were observed in the shapes of velocity profiles of the different seagrass species; in particular, a region of high water velocity was observed beneath the leafy canopy of Amphibolis, but not in the Posidonia canopy. There is a strong correlation between the water velocity profile of Amphibolis plants and the distribution of leaf biomass, highlighting the influence of the 'stem-and-leaf cluster' morphology on the velocity profile. The unusual velocity profile of Amphibolis has implications for the ecology of these ecosystems, and sediment stability in particular. The solid-state electronic current meters used in this study were found to be an effective and inexpensive means of measuring water velocity profiles in seagrass canopies
The changing face of the Constantia Valley a temporal study of land use change in a heritage landscape
Includes bibliographical references.The study of land use change and urban morphology requires a multi-layered approach. Case studies are needed to gain an understanding of the local factors that are driving land use change and forming urban landscapes. This study will provide a temporal perspective on land use change in the Constantia Valley, a high income suburb on the outskirts of Cape Town. It will contextualise the efforts to conserve its heritage and, furthermore, attempt to explain the factors underlying the observed changes in the urban form. This study, through the use of Geographic Information System (GIS) mapping and a series of interviews, examines how and why the urban form of the Constantia Valley has changed. Finally, based on the findings the possible future urban form of Constantia will be considered
