Community Sport Coaching and Impression Management
No full textThis chapter positions community sport coaching work as a social, interactive performance. It begins by introducing the concept of dramaturgy and Erving Goffman’s ground-breaking work addressing ‘the presentation of the self in everyday life. This background information is then followed by an exposition of some of Goffman’s central dramaturgical concepts and the ways in which they connect with, and could be used to inform, everyday community sport coaching practice. Here, Callum, the last author, provides detailed examples of how he has utilised these dramaturgical concepts to inform the ways in which he performs his community sport coaching role. Finally, the conclusion summarises the central arguments and issues raised in this chapter and provides some critical questions to stimulate your reflection on the dramaturgical dimensions of everyday practice

Becoming Atheist: Humanism and the Secular West
No full textThe western world is becoming atheist. In the space of three generations, churchgoing and religious belief have become alien to millions. We are in the midst of one of humankind's great cultural changes. How has this happened? Becoming Atheist offers the most thorough analysis of this phenomenon to date, exploring through their own words how people have come to live their lives as if there is no God. It tells the stories of those who have come to secular lives in Britain, western Europe, the United States and Canada, mostly from Christian and Jewish backgrounds. Based on interviews with over 80 people born in 18 countries, Callum Brown shows that a long-latent humanism has been roused in the post-1945 secularising west. Focusing on the gender, ethnic and childhood dimensions of atheists from the United Kingdom, the USA, Canada and Europe, the author looks at how the religious condition of the western world changed during the 20th and 21st centuries. By listening to individuals' life stories, this book moves away from mere statistical or broad cultural analysis. Making extensive use of frank, humorous and sometimes harrowing personal testimony, Becoming Atheist exposes the people's role in renegotiating their own identities and fashioning a secular and humanist culture for the western world
An Investigation into changes in the phytoplankton community in Loch Creran, a Scottish sea loch
No full textShort term and irregular sampling in Loch Creran over recent decades suggested that changes may be occurring in the phytoplankton community in the loch. This study sought to confirm this suggestion. After instigating a regular sampling regime during 2008 and 2009 it became clear that significant changes had occurred, relative to information from the 1970s, in both the numbers of phytoplankton in the loch and in their biomass, particularly during the time of the spring bloom. Utilising a tool to assess change in the phytoplankton community, it also became clear that significant changes had occurred in the composition of the phytoplankton in Loch Creran. Work was undertaken to explore possible explanations behind these changes.The effect that toxic, anti-fouling compounds, arising from an increase in leisure boating in Loch Creran, were having on the productivity of phytoplankton in the loch was considered by adapting an existing assimilative capacity model for phytoplankton growth. It was found, that at present levels of boating activity, the concentration of anti-fouling products present in the loch, would not be great enough to significantly impact on phytoplankton growth.Nutrient samples collected during 2009 showed no significant changes in the concentration of silicate or nitrate in the loch, but phosphate levels were found to be significantly lower. A review of the effects of grazing on phytoplankton by farmed mussels in Loch Creran indicated that, at current levels, this would not account for the decrease in phytoplankton numbers observed in the loch.Significant changes were observed in the water temperature in the loch and in the intensity and pattern of local rainfall. Increased levels of rainfall in the first three months of the year were found to be high enough to influence the rate of flushing and the rate of phytoplankton washout from the loch. A correlation was found between the availability of light in the surface layers of the loch and the concentration of phytoplankton present in these layers. This correlation was found to exist, throughout the year and not only, as previously thought, during the winter months.In conclusion, the observed decline in phytoplankton numbers in Loch Creran, was attributed to changes in local weather patterns, that had an impact on the physical structure of the water column, washout rates, the pattern and intensity of heterotrophic grazing and the availability of light
Application of adiabaticity map: highly efficient coupling from optical fibers to silicon waveguides by adiabatic mode evolution
No full textEfficient coupling of light from an optical fiber to silicon waveguides is a challenging task in integrated photonics. Couplers based on adiabatic mode evolution have the advantages of high bandwidth and low loss but are often accompanied by longer device lengths. In this paper, we introduce the concept of adiabaticity map and optimize the coupling between an optical fiber and Si waveguides by selecting routes on the map that minimize unwanted mode coupling. The map clearly indicates areas in mode evolution where supermode coupling is large and identifies optimal routes for efficient mode evolution. Optimized interaction length and widths are obtained from the adiabaticity map. We obtain highly efficient coupling (96%) with large bandwidth (1-dB bandwidth 280 nm) and misalignment tolerance (⪆90 nm lateral misalignment range for 1-dB excess losses) for the TE polarization.Dynamics of Micro and Nano System
COP26 and opening to postcapitalist climate politics, religion, and desire
No full textClimate change represents a set of emergencies for humanity. Many geographers have argued that in order to repair and avert the damage that these confluent emergencies have and may-yet cause, a postcapitalist society is necessary. However, strategies for how this might be achieved often forgo any consideration of desire, which is problematic given the influence that desire holds over the ‘popularity’ towards which a postcapitalist politics may aspire. This paper reports on a psychogeographic walk to a church in Glasgow, taken by the author during the COP26 Youth March. Reflections on the role of the church amidst the roil of protest allows the author to imagine new ways in which movements striving for a climate-conscious postcapitalist future might engage with religion and spirituality in order to direct popular desires away from and beyond further climate breakdown
Plankton community respiration and bacterial metabolism in a North Atlantic Shelf Sea during spring bloom development (April 2015)
No full textSpring phytoplankton blooms are important events in Shelf Sea pelagic systems as the increase in carbon production results in increased food availability for higher trophic levels and the export of carbon to deeper waters and the sea-floor. It is usually accepted that the increase in phytoplankton abundance and production is followed by an increase in plankton respiration. However, this expectation is derived from field studies with a low temporal sampling resolution (5–15 days). In this study we have measured the time course of plankton abundance, gross primary production, plankton community respiration, respiration of the plankton size classes (>0.8 µm and 0.2–0.8 µm) and bacterial production at ≤5 day intervals during April 2015 in order to examine the phasing of plankton autotrophic and heterotrophic processes. Euphotic depth-integrated plankton community respiration increased five-fold (from 22 ± 4 mmol O 2 m −2 d −1 on 4th April to 119 ± 4 mmol O 2 m −2 d −1 on 15th April) at the same time as gross primary production also increased five-fold, (from 114 ± 5 to 613 ± 28 mmol C m −2 d −1). Bacterial production began to increase during the development of the bloom, but did not reach its maximum until 5 days after the peak in primary production and plankton respiration. The increase in plankton community respiration was driven by an increase in the respiration attributable to the >0.8 µm size fraction of the plankton community (which would include phytoplankton, microzooplankton and particle attached bacteria). Euphotic depth-integrated respiration of the 0.2–0.8 µm size fraction (predominantly free living bacteria) decreased and then remained relatively constant (16 ± 3 – 11 ± 1 mmol O 2 m −2 d −1) between the first day of sampling (4th April) and the days following the peak in chlorophyll-a (20th and 25th April). Recent locally synthesized organic carbon was more than sufficient to fulfil the bacterial carbon requirement in the euphotic zone during this productive period. Changes in bacterial growth efficiencies (BGE, the ratio of bacterial production to bacterial carbon demand) were driven by changes in bacterial production rates increasing from 0.8 µm during the development of the spring bloom, followed 5 days later by a peak in bacterial production. In addition, the size fractionated respiration rates and high growth efficiencies suggest that free living bacteria are not the major producers of CO 2 before, during and a few days after this shelf sea spring phytoplankton bloom
