Stories of success: Cultural narratives and personal stories of elite and professional athletes
Using a narrative methodology to explore the stories Olympic and elite athletes tell about success, we identified three alternatives to the dominant conception of success as the achievement of performance outcomes. In these alternatives, success is storied as: (1) âI did the best that I couldâ â a controllable and sustainable story of effort and application; (2) âItâs the closest thing you can get to flyingâ â a story where success relates to embodied experience and discovery; (3) âPeople I made the journey withâ â which prioritises relationships and connection between people. We reflect on three key insights: (1) success is a multidimensional concept, broader than the singular conception encapsulated within the dominant performance narrative; (2) through various narrative strategies, experienced athletes resist cultural pressures towards a singular conception of success; (3) for long-term performance and well-being, it is necessary to work towards multiple forms of success over time and across contexts
ER network dynamics are differentially controlled by myosins XI-K, XI-C, XI-E, XI-I, XI-1, and XI-2
This document is protected by copyright and was first published by Frontiers. All rights reserved. It is reproduced with permission.The endoplasmic reticulum (ER) of higher plants is a complex network of tubules and cisternae. Some of the tubules and cisternae are relatively persistent, while others are dynamically moving and remodeling through growth and shrinkage, cycles of tubule elongation and retraction, and cisternal expansion and diminution. Previous work showed that transient expression in tobacco leaves of the motor-less, truncated tail of myosin XI-K increases the relative area of both persistent cisternae and tubules in the ER. Likewise, transient expression of XI-K tail diminishes the movement of organelles such as Golgi and peroxisomes. To examine whether other class XI myosins are involved in the remodeling and movement of the ER, other myosin XIs implicated in organelle movement, XI-1 (MYA1),XI-2 (MYA2), XI-C, XI-E, XI-I, and one not, XI-A, were expressed as motor-less tail constructs and their effect on ER persistent structures determined. Here, we indicate a differential effect on ER dynamics whereby certain class XI myosins may have more influence over controlling cisternalization rather than tubulation.Biotechnology & Biological Sciences Research Council (BBSRC)Biology department at Texas A and M Universit
Modeling the geometry of the endoplasmic reticulum network
Conference ProceedingFirst International Conference, AlCoB 2014, held in July 2014 in Tarragona, Spain.We have studied the network geometry of the endoplasmic reticulum by means of graph theoretical and integer programming models. The purpose is to represent this structure as close as possible by a class of finite, undirected and connected graphs the nodes of which have to be either of degree three or at most of degree three. We determine plane graphs of minimal total edge length satisfying degree and angle constraints, and we show that the optimal graphs are close to the ER network geometry. Basically, two procedures are formulated to solve the optimization problem: a binary linear program, that iteratively constructs an optimal solution, and a linear program, that iteratively exploits additional cutting planes from different families to accelerate the solution process. All formulations have been implemented and tested on a series of real-life and randomly generated cases. The cutting plane approach turns out to be particularly efficient for the real-life testcases, since it outperforms the pure integer programming approach by a factor of at least 10. © 2014 Springer International Publishing
A Scalable, Self-Analyzing Digital Locking System for use on Quantum Optics Experiments
Digital control of optics experiments has many advantages over analog control
systems, specifically in terms of scalability, cost, flexibility, and the
integration of system information into one location. We present a digital
control system, freely available for download online, specifically designed for
quantum optics experiments that allows for automatic and sequential re-locking
of optical components. We show how the inbuilt locking analysis tools,
including a white-noise network analyzer, can be used to help optimize
individual locks, and verify the long term stability of the digital system.
Finally, we present an example of the benefits of digital locking for quantum
optics by applying the code to a specific experiment used to characterize
optical Schrodinger cat states.Comment: 7 pages, 5 figure
Experiences from using Action Learning Groups to develop Sustainable Farming Systems for Central Queensland
Farmer-based action learning groups have been used to conduct on-farm research in the âSustainable Farming Systems for Central Queenslandâ project, with the aim of developing profitable and sustainable farming systems and having them adopted. Group facilitators and technical staff help guide the groups using the action learning process. This guidance, and the use of adult learning principles has ensured that groups remain focussed on achieving their goals and that profitable and sustainable farming systems are adopted. This paper details the experiences gained in facilitating action learning at key points in group development, including group formation, planning and implementing research and evaluation. Key factors needed for effectively using action learning to develop profitable and sustainable farming systems and improve adoption are identified and discusse
Narrative, identity, and recovery from serious mental illness: A life history of a runner
In recent years, researchers have investigated the psychological effects of exercise for people with mental health problems, often by focusing on how exercise may alleviate symptoms of mental illness. In this article I take a different tack to explore the ways in which exercise contributed a sense of meaning, purpose, and identity to the life of one individual named Ben, a runner diagnosed with schizophrenia. Drawing on life history data, I conducted an analysis of narrative to explore the narrative types that underlie Ben's stories of mental illness and exercise. For Ben, serious mental illness profoundly disrupted a pre-existing athletic identity removing agency, continuity, and coherence from his life story. By returning to exercise several years later, Ben reclaimed his athletic identity and reinstated some degree of narrative agency, continuity, and coherence. While the relationships between narrative, identity, and mental health are undoubtedly complex, Ben's story suggests that exercise can contribute to recovery by being a personally meaningful activity which reinforces identity and sense of self
Challenges of on-farm research - insights from the Central Queensland farming systems experience
The âSustainable Farming Systems for Central Queenslandâ project aims to develop profitable and sustainable farming systems in central Queensland and to have these systems widely adopted. Farmer-based groups are involved in on-farm research into system components at ten locations in central Queensland, with project staff facilitating and guiding this research and system development.
At the projectâs inception, on-farm research was seen as a means of integrating Research, Development and Extension (R,D&E), resulting in research outcomes relevant to producers therefore improving the rate of adoption. Although the use of on-farm research has produced locally relevant system components that are being adopted, using this methodology has not been without its challenges. This paper describes the experiences of the authors in implementing on-farm research, detailing the challenges faced and methods used to deal with them
