Background: Interpersonal coordination is an essential aspect of daily life, and crucial to performance in cooperative and competitive team sports. While empirical research has investigated interpersonal coordination using a wide variety of analytical tools and frameworks, to date very few studies have employed multifractal techniques to study the nature of interpersonal coordination across mul…
Literate individuals possess knowledge and skill and can apply these to perform tasks in novel settings. Knowledge is at the heart of physical literacy and provides the foundation for knowing what to do and how and when to perform. In this paper I argue that physical literacy includes not only knowledge for performance but also the ability to apply knowledge and use knowledge for innovation. Sc…
Purpose: The purpose of this study was to examine the effects of landing on a combined inversion and plantarflexion surface on the ankle kinematics and electromyographic (EMG) activities of medial gastrocnemius (MG), peroneus longus (PL), and tibialis anterior (TA) muscles. Methods: Twelve recreational athletes performed five drop landings from an overhead bar of 30 cm height on to three surfa…
Objectives: Heart rate variability (HRV) can be a simple, non-invasive method of gauging cardiac autonomic nervous system fluctuations across periodised training workloads and taper in elite athlete populations. The purpose of these three case studies was to examine daily cardiac autonomic variations in Paralympic athletes leading in to the Paralympic games. Methods: Three Paralympic gold medal…
Brain injuries in sports drew more and more public attentions in recent years. Brain injuries vary by name, type, and severity in the athletic setting. It should be noted, however, that these injuries are not isolated to only the athletic arena, as non-athletic mechanisms (e.g., motor vehicle accidents) are more common causes of traumatic brain injuries (TBI) among teenagers. Notwithstanding, a…
Purpose: The purpose of the study was to examine the psychometric properties of the Chinese-translated Behavioral Regulation in Exercise Questionnaire-2 (C-BREQ-2) among Chinese university students from the Mainland and Hong Kong of China. Methods: University students from the Mainland (n ¼ 191) and Hong Kong (n ¼ 194) of China participated in this study. Factorial validity,discriminant vali…
Background: Many studies examining individual-level correlates in youth utilize self-report rather than objective measures of physical activity (PA). This utilization of self-report may result in associations that are not present when examining objectively measured PA. The present study investigates the relationship between hypothesized correlates of PA with objectively and subjectively measure…
Background: It has been reported that strenuous exercise increases the number of bone marrow-derived progenitor cells such as CD34þ cells in the blood, but no previous studies have investigated the changes in circulating CD34þ cells following resistance exercise. This study tested the hypothesis that the number of CD34 þ cells in the blood would increase after eccentric exercise of the elbow…
Background: Among numerous health benefits, sports participation has been shown to reduce the risk of overweight and obesity in children and adolescents. Schools represent an ideal environment for increasing sports participation, but it is unclear how access and choice influence participation and whether characteristics of the school sports program differentially influence boys’ and girls’ …
Background: Regular exercise is beneficial for adults with cardiovascular disease (CVD) and CVD risk factors. Tai Ji Quan is popular among older adults and may offer additional exercise options. The present article aims to review the scientific literature published within the past decade on Tai Ji Quan as an exercise modality to prevent and manage CVD. Methods: An electronic literature search o…
Sport-related concussion is a common neurological injury that occurs in all levels of athletic participation. Concussions may actually go undiagnosed, as they do not always display outward signs and athletes may fail to report symptoms of concussion, either because they do not know the symptoms, or for fear of removal from play. Inappropriate management of concussion can lead to increased risk …
Reactive oxygen species (ROS) are continuously generated during aerobic metabolism and at moderate level. They play a role in redox signaling, but in significant concentration they cause oxidative damage and neurodegeneration. Because of the enhanced sensitivity of brain to ROS, it is especially important to maintain the normal redox state in different types of neuron cells. In last decade it b…
Purpose: To assess the effects of trust in the coach on commitment to coach, willingness to cooperate, and perceived performance. Methods: Two hundred and fifteen members of competitive sports clubs responded to scales measuring coach characteristics of justice,benevolence, integrity, and competence; athlete’s trust in the coach; commitment to coach; willingness to cooperate; and perceived p…
The literature presented here was originally developed partially as class notes and handouts for the Advanced International Course for the Identification of Marine Phytoplankton, held in Oslo, Norway, and later in Naples, Italy. This material, continuously revised and updated by the authors, is an effort to synthesize the latest information with that published previously, often in different…
Having been involved for more than 15 years in wind, wave, and storm surge research, we have been in contact with many people having different interests in these topics. Most of them were seeking long time series of data over the often poorly sampled coastal, offshore, and ocean regions. We have collaborated with a shipyard developing RoRo and RoPax ferries operating on fixed routes. Enviro…
The 1984 edition of this book grew out of my conviction that at the heart of any applied science is a determination to bring to the solution of significant problems both a mastery of relevant technical information and a sensitivity to social values. The 1996 edition continues in that direction but gives extra emphasis to our fishery management failures and the accelerating professional cha…
A comprehensive study of cohesive sediment requires a multi-disciplinary approach. The behaviour of cohesive sediment is determined by physical, biological and chemical aspects. Furthermore, there is a wide range of societal issues related to cohesive sediments, such as siltation in navigational channels, water quality problems, sustainable management of estuaries and wetlands, stability o…
Small populations are predicted to perform poorly relative to large populations when experiencing environmental change. To explore this prediction in nature,data from reciprocal transplant, common garden, and translocation studies were compared meta-analytically. We contrasted changes in performance resulting from transplantation to new environments among individuals originating from different…
The past two decades have witnessed a growing body of research that draws on post-structuralist theory to interrogate environmental discourses in planning. Grounded in the interpretative tradition,this approach rejects essentialist ontology to assume environmental discourses being socially constructed and linked to different policy arenas at multiple geographical scales. Widely applied in the e…
Both ‘spatial skewness’ in population sizes, incomes and house prices and ‘agglomeration economies’are important features in many countries. This paper uses a solvable core-periphery model capturing the two features to specify a market-induced housing boom under the condition of a fixed or very inelastic housing supply. Two main insights emerge from our analysis. First, there exists a r…
The proliferation of streetcar projects in US cities is one of the most significant transportation developments of recent years, yet little is known about the factors that contribute to streetcar ridership or whether these factors differ from those related to light rail transit use. This study uses multivariate models to examine differences in the factors related to average weekday station boar…
This paper explains the importance of distinguishing de facto from de jure property rights, confused by some economists, in heritage conservation planning. A comparative study on three Hong Kong examples of British colonial military buildings is used to show how neither de jure private property rights nor de facto close access is a solution to the problem of open access to heritage buildings. A…
Drawing on in-depth stakeholder interviews and media accounts, we explore a case of civic activism over the opening of a strip club in a neighbourhood of Etobicoke, one of six municipalities amalgamated in 1998 to form the current City of Toronto, Ontario. In 2008, the growing residential gentrification of the area had not yet extended into the commercial district and the opening of the strip c…
With increased inequity and polarisation in society, access to leisure has become even more crucial for ensuring the humanity and health of people living in urban poverty. Homeless people constitute the hard edge of urban poverty, and literally embody broader inequities in society given that they face increased risk of illness and an early death. Scholars have explored the material and psychoso…
The Tiebout hypothesis has stimulated 50 years of research into the relationship between residential location and local taxes and services. One line of research has focused on socioeconomic homogeneity as an indicator of Tiebout sorting. I argue that spatial dependence of socioeconomic variables confounds attempts to attribute sorting to Tiebout processes. Socioeconomic sorting is investigated …
It is well-recognised in labour economics that employers in monopsonistic competition have market power to set wages below the productivity of workers if workers are immobile, which causes monopsonistic exploitation of workers. Monopsonistic exploitation is propelled by employers’expectations about the degree of (im)mobility of workers and therefore by ex post mobility of workers. It hence be…
This paper reflects upon intellectual possibilities of Raymond Williams’ classic study The Country and the City (1975) within current urban and regional research. First, the paper canvasses the relevance of the book by constructing a frame of reference based on its citations in urban and regional studies. The principal findings of this approach discern frequent use of the main points develope…
This paper investigates the heterogeneity of housing-tenure choice in the city of Guangzhou based on a household survey. Using methods of finite mixture regression, we identified three groups with distinct housing-tenure choice subprocesses, which we labelled as the ‘urban elites’,the ‘native plebeians’ and the ‘lower masses’, accordingly. The urban elites group includes affluent lo…
Most Dutch cities have adopted urban restructuring policies aimed at creating a socially mixed population in deprived neighbourhoods. This entails the demolition of low-cost, social rented housing units, which leads to the displacement of their residents. While researchers have investigated the social effects of displacement on adults, this study is the first to provide insight into the effects…
Managing urban growth is inherently contentious. Government policies seek to facilitate and spatially contain growth, while balancing public and private interests. The need for climate adaptation strategies in the urban context is recognised but arguably poorly institutionalised in growth management policies or in urban governance more broadly. This paper considers how debates around urban adap…
This article explores youth drinking in Zurich, Switzerland, on both public squares away from nightlife areas, referred to as ‘square street drinking’ and on the street within the vicinity of nightclubs, defined as ‘club street drinking’. Taking a relational space approach, the analysis adds a social perspective to the dominant economicpolitical perspective to drinking in urban nightli…
Urban residential neighbourhoods, including migrant neighbourhoods, have become important incubation zones for small businesses in recent years and policy-makers and academics alike are wondering which local factors affect this development. This paper analyses the extent to which migrant neighbourhood characteristics related to the built environment and the local regulations matter in determini…
Abstract This paper considers the very large differences in adaptive capacity among the world’s urban centres. It then discusses how risk levels may change for a range of climatic drivers of impacts in the near term (2030–2040) and the long term (2080–2100) with a 2°C and a 4°C warming for Dar es Salaam, Durban,London and New York City. The paper is drawn directly from Chapter 8 of C…
This paper reviews what local governments in more than 50 cities are doing with regard to disaster risk reduction. It draws on the reports of their participation in the global Making Cities Resilient Campaign and its 10 “essential” components, and on interviews with city mayors or managers. These show how resilience to disasters is being conceived and addressed by local governments,especia…
The relationship between the built environment and vulnerability and resilience is a little-studied area of research, and demands an exploration of constraints and windows of opportunity. Given gender roles and the division of labour between women and men within urban poor households, the impacts of climate extremes are likely to be gendered. But conceptualizing gender only in terms of the vul…
This paper is a report on one of three related case studies in Latin America and shows the progress in the city of Chetumal, and the larger state of which it is the capital (Quintana Roo), in disaster response, especially with regard to cyclones. It also shows the progress in land use and ecological planning through the development of certain tools, which have changed the approach from one of …
The relationship between “coping” and “resilience” increasingly features in academic, policy and practical discussions on adaptation to climate change in urban areas. This paper examines this relationship in the context of households in “extreme poverty” in the city of Khulna, Bangladesh. It draws on a quantitative data set based on 550 household interviews in low-income and informa…
During the last few decades, the theoretical research on marine systems, particularly in numerical modelling, has developed rapidly. A number of biogeochemical models, population models and coupled physical chemical and biological models have been developed and are used for research. Although this is a rapidly growing field, as documented by the large number of publications in the scientif…
We began to formulate the initial ideas for this Manual as early as 2006. It had become apparent to us that civil and structural engineers not specialising in geotechnics face a daunting knowledge gap when they come up against a geotechnical problem. Most civil engineers leave university with very little grounding in geotechnical engineering. They will have a fair grasp of applied mechanics …

This paper engages my struggles to craft geo-graphs or earth writings that also further broaden political goals of decolonizing the discipline of geography. To this end, I address a body of literature roughly termed ‘posthumanism’ because it offers powerful tools to identify and critique dualist constructions of nature and culture that work to uphold Eurocentric knowledge and the colonial p…
This paper asks how Indigenous ways of being and knowing can become legitimized within western theorizations of ontology, given the ongoing (neo)colonial relations that shape geographic knowledge production. My analysis emerges within my narrative accounts of being a Kwakwaka’wakw scholar in two spaces of knowledge production: a geography conference and a potlatch. Through these stories, I en…
This short reflection on my writing practice pivots off Roland Barthes’ announcement, in his last lecture course The Preparation of the Novel 1978–80, that he wanted ‘to track the Work from its Projection to it’s accomplishment: in other words, from Wanting-to-Write to Being-Able-to- Write, or from the Desire-to-Write to the Fact-of-Writing’. Here I reflect how Barthes, through animat…
For most academic geographers writing remains the primary means through which we communicate our work. Typically, of course, in monographs and journal articles, but with ongoing creative efforts to engage geographical audiences through practices beyond academic publishing – something cultural geographies in practice has long featured – that writing sees a myriad of expressions.1 Nevertheles…
This contribution is a reflection on the process of becoming a poet as a geographer. It charts my journey into the world of poetry and reflects on the cross-overs between academic geography and poetic practice in the past. It considers the way in which geography and poetry can inform each other in the practice of writing creatively, and tentatively suggests how this engagement might influence m…
This article examines the period leading up to the establishment of the Schefferville iron mine in subarctic Québec, Canada, with a focus on the years 1937–54. The beginning of iron ore mining at Schefferville was a decisive moment in the growth of the modern Québec state, opening the way for the industrial exploitation of the province’s natural resources – mineral and otherwise – in …
The first challenge faced by a project that seeks to bring concerns with ontology and indigeneity into a conversation is to sort out the various (and possibly divergent) projects that are being mobilized when the former term is used, not the least because what do we mean by ontology impinges upon how we can conceive indigeneity. In this article I play a counterpoint between two ‘ontological�…
Evolutionary responses that rescue populations from extinction when drastic environmental changes occur can be friend or foe. The field of conservation biology is concerned with the survival of species in deteriorating global habitats. In medicine, in contrast, infected patients are treated with chemotherapeutic interventions,but drug resistance can compromise eradication of pathogens. These co…
In this report, we critically reviewed selected intrinsic physicochemical properties of engineered nanomaterials (ENMs) and their role in the interaction of the ENMs with the immediate surroundings in representative aquatic environments. The behavior of ENMs with respect to dynamic microenvironments at the nanoebioeeco interface level, and the resulting impact on their toxicity, fate, and expo…
