Insights on the Process of Using Interpretive Phenomenological Analysis in a Sport Coaching Research Project

Interpretative Phenomenological Analysis (IPA) is a qualitative research methodology used to understand participants’ subjective realities through personal interpretations of their lived experiences and the meanings they attach to these experiences (Smith, 2011). IPA has been used predominantly in health psychology, with rising interest within the field of sport psychology and coaching. This article seeks to describe insights about the processes of IPA by a research team using the methodological approach for the first time. These experiences are shared against the backdrop of research exploring the lived experiences of Masters athletes within the context of coached competitive swim programs. We describe how the multiple facets of IPA influence the refinement of the research question, the planning and implementation of data collection, and data analysis and interpretation. We elaborate on our perceptions of the complexities of IPA and make recommendations for how future research teams might smoothly navigate the rigorous research process to yield rich in-depth data and interpretations

Exploring the Context of Coached Masters Swim Programs: A Narrative Approach

Knowing the psychosocial themes in a specific sport context allows us to understand athletes’ experiences and informs approaches of coaches (Côté et al., 1995) and sport programmers (Danish et al., 2005). Few qualitative studies focus on psychosocial conditions of adult athletes in coached sport settings. The purpose of this study was to capture important psychosocial themes from the perspective of Masters swimmers involved in day-to-day coached swimming environments. Data were collected using semi-structured open-ended interviews with 10 competitive swimmers (5 male, 5 female; M age = 53 years; range: 45-65 years). Analyses revealed four over-arching themes that represented athletes’ a) motives for swimming, b) perspectives on competition, c) experiences specific to being a Masters swimmer, and d) perspectives on being coached. Using a qualitative narrative approach (Denison, 2011), we developed three narrative profiles to depict how our Masters swimmers had different experiences relating to these themes. Discussion focuses on how swimmers’ understanding of the four over-arching themes depends on their profile

Unseen is Unsold: Assessing Visual Equity with Commercial Eye-Tracking Data

In today’s cluttered retail environments, creating consumer pull through memory-based brand equity is not enough; marketers must also create “visual equity” for their brands (i.e., incremental sales triggered by in-store visual attention). In this paper, we show that commercial eye-tracking data, analyzed using a simple decision-path model of visual attention and brand consideration, can separately measure memory-based and visual equity of brands displayed on a supermarket shelf. In the two product categories studied, juices and detergents, we find that instore visual attention doubles on average the memory-based probability of consideration. Additionally, our empirical applications and normative analyses show how separating memorybased and visual equity can help improve managerial decisions about which brands to select for enhanced point-of-purchase marketing activities

SWAT raids are more about symbolism than reducing crime in the long term.

SWAT raids are among the most dramatic display of the power of law enforcement to deal with crime and disorder. But are SWAT raids actually effective at reducing crime? In new research which studies 39 SWAT raids in Buffalo, New York, Dae-Young Kim, Scott W. Phillips and Andrew P. Wheeler find that the raids did lead to fewer street crimes involving property – though only for a short time, and that they had no deterrent effect on violent crimes in private places, drug arrests, or calls for service

Effects of carbon dioxide on the searching behaviour of the root-feeding clover weevil <i>Sitona lepidus</i> (Coleoptera: Curculionidae)

The respiratory emission of CO2 from roots is frequently proposed as an attractant that allows soil-dwelling insects to locate host plant roots, but this role has recently become less certain. CO2 is emitted from many sources other than roots, so does not necessarily indicate the presence of host plants, and because of the high density of roots in the upper soil layers, spatial gradients may not always be perceptible by soil-dwelling insects. The role of CO2 in host location was investigated using the clover root weevil Sitona lepidus Gyllenhall and its host plant white clover (Trifolium repens L.) as a model system. Rhizochamber experiments showed that CO2 concentrations were approximately 1000 ppm around the roots of white clover, but significantly decreased with increasing distance from roots. In behavioural experiments, no evidence was found for any attraction by S. lepidus larvae to point emissions of CO2, regardless of emission rates. Fewer than 15% of larvae were attracted to point emissions of CO2, compared with a control response of 17%. However, fractal analysis of movement paths in constant CO2 concentrations demonstrated that searching by S. lepidus larvae significantly intensified when they experienced CO2 concentrations similar to those found around the roots of white clover (i.e. 1000 ppm). It is suggested that respiratory emissions of CO2 may act as a ‘search trigger’ for S. lepidus, whereby it induces larvae to search a smaller area more intensively, in order to detect location cues that are more specific to their host plant.<br/

Assessing and Improving Library Technology with Service Blueprinting

Objective: The objective of this article is to illustrate the application of service blueprinting—a design tool that comes from the service design tradition—for assessing and improving library technology services. Setting: A mid-sized library at a public university in the western United States. Methods: A service blueprint was co-created by library and IT staff in a design workshop in order to map the operational flow of a data visualization display wall. Results: Guided by the service blueprint, the project team identified points of improvement for the service of the data visualization display wall, and developed recommendations to aid further applications of service blueprinting. Conclusions: Ultimately, service blueprinting was found to be a useful tool that can be applied to assess and improve library technology services

Superoxide dismutase downregulation in osteoarthritis progression and end-stage disease

Oxidative stress is proposed as an important factor in osteoarthritis (OA). To investigate the expression of the three superoxide dismutase (SOD) antioxidant enzymes in OA. SOD expression was determined by real-time PCR and immunohistochemistry using human femoral head cartilage. SOD2 expression in Dunkin–Hartley guinea pig knee articular cartilage was determined by immunohistochemistry. The DNA methylation status of the SOD2 promoter was determined using bisulphite sequencing. RNA interference was used to determine the consequence of SOD2 depletion on the levels of reactive oxygen species (ROS) using MitoSOX and collagenases, matrix metalloproteinase 1 (MMP-1) and MMP-13, gene expression. All three SOD were abundantly expressed in human cartilage but were markedly downregulated in end-stage OA cartilage, especially SOD2. In the Dunkin–Hartley guinea pig spontaneous OA model, SOD2 expression was decreased in the medial tibial condyle cartilage before, and after, the development of OA-like lesions. The SOD2 promoter had significant DNA methylation alterations in OA cartilage. Depletion of SOD2 in chondrocytes increased ROS but decreased collagenase expression. This is the first comprehensive expression profile of all SOD genes in cartilage and, importantly, using an animal model, it has been shown that a reduction in SOD2 is associated with the earliest stages of OA. A decrease in SOD2 was found to be associated with an increase in ROS but a reduction of collagenase gene expression, demonstrating the complexities of ROS function

Neural responses to facial and vocal expressions of fear and disgust

Neuropsychological studies report more impaired responses to facial expressions of fear than disgust in people with amygdala lesions, and vice versa in people with Huntington's disease. Experiments using functional magnetic resonance imaging (fMRI) have confirmed the role of the amygdala in the response to fearful faces and have implicated the anterior insula in the response to facial expressions of disgust. We used fMRI to extend these studies to the perception of fear and disgust from both facial and vocal expressions. Consistent with neuropsychological findings, both types of fearful stimuli activated the amygdala. Facial expressions of disgust activated the anterior insula and the caudate-putamen; vocal expressions of disgust did not significantly activate either of these regions. All four types of stimuli activated the superior temporal gyrus. Our findings therefore (i) support the differential localization of the neural substrates of fear and disgust; (ii) confirm the involvement of the amygdala in the emotion of fear, whether evoked by facial or vocal expressions; (iii) confirm the involvement of the anterior insula and the striatum in reactions to facial expressions of disgust; and (iv) suggest a possible general role for the perception of emotional expressions for the superior temporal gyrus

Determining the fate of selenium in wheat biofortification: an isotopically labelled field trial study

Aims The principal aim of this research was to quantify retention of a single, realistic Se biofortification application (10 g ha-1) in contrasting soils over two growing seasons utilizing an enriched stable Se isotope (77Se) to discriminate between applied Se and native soil Se. Methods Isotopically enriched 77Se (Na2SeO4) was applied (10 g ha-1) to four replicate plots (2 m x 2 m) of winter wheat, on three contrasting soils on the University of Nottingham farm (UK), at early stem extension in May 2012. Labelled 77Se was assayed in soil and crop fractions by ICP-MS. Results Topsoil retained a proportion of applied Se at harvest (c. 15 – 31 %) with only minor retention in subsoil (2-4 %), although losses were 37 – 43 %. Further analysis of topsoil 77Se, the following spring, and at second harvest, suggested that labelled Se retained in soil was25 fixed and uptake by a following crop was negligible. Conclusions Prolonged biofortification leads to accumulation of Se in soil but the retained Se has very low bioavailability and mobility. The time required to double the soil Se content would be about 500 years. However, reincorporation of cereal straw could provide a residual source of Se for a following crop, depending on timing and management
