Push-off mechanics in speed skating with conventional skates and klapskates [PDF]

Medicine & Science in Sports & Exercise, 2000
Personal and world records in speed skating improved tremendously after the introduction of the klapskate, which allows the foot to plantar flex at the end of the push-off while the full blade continues to glide on the ice. The purpose of this study was to gain insight into the differences in skating technique with conventional versus klapskates and to

Which Decolonization? Theorizing Decolonization beyond Decoloniality and its Critics

Development and Change, EarlyView.
ABSTRACT The debate on decolonial thought has reached an unhelpful stalemate. A core problem in assessing decolonial thought is that the term ‘decolonization’ has been stretched so widely that it now allows for many competing uses. For some critics of decolonial thought such as Nigerian philosopher Olúfẹ́mi Táíwò, this overuse points to conceptual ...

Integrability and Chaos in Figure Skating [PDF]

Journal of Nonlinear Science, 2019
We derive and analyze a three dimensional model of a figure skater. We model the skater as a three-dimensional body moving in space subject to a non-holonomic constraint enforcing movement along the skate's direction and holonomic constraints of continuous contact with ice and pitch constancy of the skate. For a static (non-articulated) skater, we show

The aesthetic sublime of megaproject structures: A framework and a research agenda

European Management Review, EarlyView.
Abstract The physical structures of megaprojects—such as mega‐canals, metros, railway lines, bridges, tunnels, and iconic opera houses—hold a profound capacity to generate aesthetic experiences with enduring societal impact. Yet, research on megaprojects has predominantly focused on functionality and economic rationale with aesthetics being pushed to ...

Black Fugitivity in the Sporting Workplace: The Story of Eniola Aluko

Gender, Work &Organization, EarlyView.
ABSTRACT Being a Black fugitive involves constant movement: to find and cultivate spaces of safety and hope. In this paper, I curate a sporting archive about the UK Black women's elite football player Eniola Aluko to read her as a Black fugitive. I demonstrate how she traversed a racist and anti‐Black sporting workplace—where she was unfairly demonized

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

Journal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

The state of knowledge on four families of Syngnathoidei fishes (Teleostei: Syngnathiformes): Aulostomidae, Centriscidae, Fistulariidae and Solenostomidae

Journal of Fish Biology, EarlyView.
Abstract Knowledge on the ecology and life‐history traits of coastal marine species is vital to inform their conservation and management, especially as their coastal habitats come under increasing threats. However, such data have never been collated for four of the five families in the suborder Syngnathoidei—the close relatives of the better‐studied ...

Distribution and ecology of the four Macrourus species by‐caught in the longline fishery at South Georgia, Southern Ocean

Journal of Fish Biology, EarlyView.
Abstract Although Macrourus species are the main by‐catch across Southern Ocean longline fisheries, including around South Georgia, the lack of species‐specific data has hindered effective management and ecological understanding. Aggregation of macrourids at genus level masks critical interspecific differences in life‐history strategies and ...

Endurance in Speed Skating

SSRN Electronic Journal, 2001
We analyse the development of world records speed skating from 1893 to 2000 for both men and women. The historical data show that it is likely that the relation between skating speed and distance of the various events is non-linear and converges to a limit value.
