The role of courage in the development and practice of coaches
This study seeks to understand the role that courage plays in the development and practice of coaches. Courage is mentioned frequently in the coaching literature, but this research is the first study to investigate its significance. Within the precepts of constructivist grounded theory, which is appropriate for the investigation of under-represented topics, the perspectives of 12 coaches of varying levels of experience revealed that courage is required throughout a coaching career. It was found that courage enables coaches to deliver their best work and is integral to an ongoing cycle of increasing self-awareness and professional development

Library log analysis and its implications for studying online information seeking behavior of cultural groups
Log analysis, as one of the less overtly intrusive ways to study information seeking behavior online, has been used to closely monitor patterns of user system usage looking at activities and actions since the 1980s (Villén-Rueda et al., 2007). However, to date there have been limited studies discussing its usage in respect of information seeking behaviors of cultural groups in the academic library context. With the growth in international student numbers, the increasing remote use of the library service and a globally connected digital environment, the particular needs and behaviors of different cultural groups, when studying in different settings, merits far greater attention.
This paper uses a library log analysis in order to explore international Chinese users' usage of an academic library in the UK and discusses the implication of it as a research method in Library and Information Studies (LIS) research, reflecting on the potential for greater analysis of different cultural groups. The findings demonstrate that log analysis can be used as a method to better understand particular cultural groups information seeking behaviors; it also discusses the limitations of log analysis and gives suggestions for future research work
A Study of Methods for Detecting Gene Expression of the Sterol Biosynthetic Pathway in the Microalgae Strain Heterosigma akashiwo
Biotechnological applications for various microalgae strains are beginning to bloom. There is interest in these microbes for their production of useful compounds such as phytosterols and lipids which can be produced in mass culture for large scale manufacture in the food, pharmaceutical, and biofuel industries (Romano et al., 2016). To this end, we are using the gold-brown microalgae, Heterosigma akashiwo (CCMP1680), a known producer of phytosterols, to test a molecular method for quick and easy measurements of production of the phytosterol compound sitosterol, which has potential as an anti- inflammatory agent. (Giner et al., 2008)
Limitations to Contingency Measures: Reflections from COVID-19 Surges in the UK
Alfandre et al. (2021) helpfully outlines the case for attending to contingency planning as well as to crisis measures during a pandemic. The authors provides a helpful framework for reflecting on the experiences of healthcare staff during COVID-19 to develop a more robust contingency phase. We do so, ourselves, in the context of the United Kingdom, particularly London where the prevalence of COVID-19 stretched resources despite considerable and continuing efforts to increase capacity as the depth of the crisis was understood. Recognizing the inevitable increase in cases once community transmission took hold, the UK government’s strategy was to keep case load manageably within the capacity of the National Health Service (NHS). All public health interventions were modeled and planned accordingly with insufficient regard to contingencies
Concentrations and ratios of particulate organic carbon, nitrogen, and phosphorus in the global ocean
Knowledge of concentrations and elemental ratios of suspended particles are important for understanding many biogeochemical processes in the ocean. These include patterns of phytoplankton nutrient limitation as well as linkages between the cycles of carbon and nitrogen or phosphorus. To further enable studies of ocean biogeochemistry, we here present a global dataset consisting of 100,605 total measurements of particulate organic carbon, nitrogen, or phosphorus analyzed as part of 70 cruises or time-series. The data are globally distributed and represent all major ocean regions as well as different depths in the water column. The global median C:P, N:P, and C:N ratios are 163, 22, and 6.6, respectively, but the data also includes extensive variation between samples from different regions. Thus, this compilation will hopefully assist in a wide range of future studies of ocean elemental ratios
Experimental Study on the Evaluation of Necking and Fracture Strains in Sheet Metal Forming Processes
In this paper the formability of AA2024-T3 metal sheets is experimentally analyzed. For this purpose, a series of StretchBending
and Incremental Sheet Forming (ISF) tests are carried out. The former tests allow determine the formability limits
through the evaluation of necking and fracture using the optical deformation measurement system ARAMIS® and measuring
the thickness strains along the fracture line. The latter are performed with the aim of confirming the validity of these limits. In
this case, the spifability, formability in Single Point Incremental Forming (SPIF), was studied in the light of circle grid analysis
by means of the 3D deformation digital measurement system ARGUS®. Different punch diameters are used in both processes.
The results exhibit the importance of the accuracy in the setting of the formability limits as well as the variability that these
limits present depending on the forming process or some variables such as the tool radius.Ministerio de Ciencia e InnovaciĂłn DPI 2009-1333
Sargasso Sea phosphorus biogeochemistry : an important role for dissolved organic phosphorus (DOP)
© The Authors, 2010. This article is distributed under the terms of the Creative Commons Attribution 3.0 License. The definitive version was published in Biogeosciences 7 (2010): 695-710, doi: 10.5194/bg-7-695-2010Inorganic phosphorus (SRP) concentrations in the subtropical North Atlantic are some of the lowest in the global ocean and have been hypothesized to constrain primary production. Based upon data from several transect cruises in this region, it has been hypothesized that dissolved organic phosphorus (DOP) supports a significant fraction of primary production in the subtropical North Atlantic. In this study, a time-series of phosphorus biogeochemistry is presented for the Bermuda Atlantic Time-series Study site, including rates of phosphorus export. Most parameters have a seasonal pattern, although year-over-year variability in the seasonal pattern is substantial, likely due to differences in external forcing. Suspended particulate phosphorus exhibits a seasonal maximum during the spring bloom, despite the absence of a seasonal peak in SRP. However, DOP concentrations are at an annual maximum prior to the winter/spring bloom and decline over the course of the spring bloom while whole community alkaline phosphatase activities are highest. As a result of DOP bioavailability, the growth of particles during the spring bloom occurs in Redfield proportions, though particles exported from the euphotic zone show rapid and significant remineralization of phosphorus within the first 50 m below the euphotic zone. Based upon DOP data from transect cruises in this region, the southward cross gyral flux of DOP is estimated to support ~25% of annual primary production and ~100% of phosphorus export. These estimates are consistent with other research in the subtropical North Atlantic and reinforce the hypothesis that while the subtropics may be phosphorus stressed (a physiological response to low inorganic phosphorus), utilization of the DOP pool allows production and accumulation of microbial biomass at Redfield proportions.This research was supported
