Advances in Visual Methodology

In recent years we have witnessed a ‘visual turn’ in the social sciences, as an increasing number of scholars are engaging with visual methodologies for the collection, analysis, and display of both qualitative and quantitative data. To mention an example, video ethnography is gaining momentum across a range of disciplines, at a time when social scientists are increasingly concerned with capturing the minutiae and details of social practices. What is more, recent developments in information technology are extending the range of techniques for the capture and analysis of visual data, therefore opening up new possibilities for research and practice. It is no coincidence that several books on visual methodologies were published in the last ten years (Margolis & Pauwels, 2011; Rose, 2007; Van Leeuwen & Jewitt, 2001) and an entire volume on visual data analysis was included in the SAGE collection on qualitative research methods (Banks & Flick, 2007). But what is distinctive about Sarah Pink’s Advances in Visual Methodology is the attempt to establish visual methodology as an interdisciplinary field of practice, while recognizing the interconnectedness of theory, technology and methods

Visualizing practices in project-based design : tracing connections through cascades of visual representations

Project-based design involves a variety of visual representations, which are evolved to make decisions and accomplish project objectives. Yet, such mediated and distributed ways of working are difficult to capture through ethnographies that examine situated design. A novel approach is developed that follows cascades of visual representations; and this is illustrated through two empirical studies. In the first case, Heathrow Terminal 5, analysis starts from paper- and model-work used to develop design, tracing connections forward to an assembly manual that forms a ‘consolidated cascade ’ of visual representations . In th e second, the Turning Torso, Malmö, analysis starts from a planning document, trac ing connections backward to the paper - and model - work done to produce this consolidated cascade . Th is work makes a twofold contribution : First, it offer s a methodological app roach that supplements ethnographies of situated design. This allows the researcher to be nimble, tracing connections across complex engineering projects; reconstructing practices through their visual representations; and observing their effects. Second, it articulate s how , in these empirical cases, interaction with a cascade of visual representations enabled participants in project - based design to develop and share understanding. T he complexity of projects , and their distributed and mediated nature makes this approach timely and important in address ing new research questions and practical challenges

Constructing shared professional vision in design work: the role of visual objects and their material mediation

The design process requires coordination between professions that have different ways of seeing. Using ethnographic data from a building project, this paper explores how architects and engineers mobilize visual objects to coordinate their professional visions around a design issue. The findings articulate the visual practices whereby design professionals move from a fragmented towards a shared professional vision. In this move, they cease looking at the design issue from within their disciplinary perspective, and begin taking inspiration from each other’s. They further adjust the emergent shared professional vision, by iteratively narrowing and broadening its focus. The paper contributes to the practice perspective in design studies, explaining how different ways of seeing are coordinated through practical engagement with visual objects

Improving the Shelf-Life of Fish Burgers Made with a Mix of Sea Bass and Sea Bream Meat by Bioprotective Cultures

Seafood products are one of the most perishable foods, and their shelf life is limited by enzymatic and microbial spoilage. Developing methods to extend the shelf life of fresh fish could reduce food waste in the fishery industry, retail stores, and private households. In recent decades, the application of lactic acid bacteria (LAB) as bioprotective cultures has become a promising tool. In this study, we evaluated the use of four starter cultures, previously selected for their properties as bioprotective agents, for sea bass and sea bream burgers biopreservation. Starter cultures impacted the microbial populations, biochemical parameters (pH, TVB-N), and sensory properties of fish burgers, during 10 days of storage at 4 degrees C and then 20 days at 8 degrees C in modified atmosphere packaging (MAP). Also, storage time influenced the microbial and physicochemical characteristics of all the tested samples, except for TVB-N values, which were significantly higher in the uninoculated burgers. The volatilome changed in the different treatments, and in particular, the samples supplemented with starter presented a profile that described their rapid growth and colonization, with the production of typical molecules derived from their metabolism. The addition of bioprotective cultures avoided bloating spoilage and improved the sensory parameters of the burgers. The shelf life of the fish burgers supplemented with starter cultures could be extended up to 12 days

Timed rise from floor as a predictor of disease progression in Duchenne muscular dystrophy: An observational study

The role of timed items, and more specifically, of the time to rise from the floor, has been reported as an early prognostic factor for disease progression and loss of ambulation. The aim of our study was to investigate the possible effect of the time to rise from the floor test on the changes observed on the 6MWT over 12 months in a cohort of ambulant Duchenne boys.A total of 487 12-month data points were collected from 215 ambulant Duchenne boys. The age ranged between 5.0 and 20.0 years (mean 8.48 ±2.48 DS).The results of the time to rise from the floor at baseline ranged from 1.2 to 29.4 seconds in the boys who could perform the test. 49 patients were unable to perform the test at baseline and 87 at 12 month The 6MWT values ranged from 82 to 567 meters at baseline. 3 patients lost the ability to perform the 6mwt at 12 months. The correlation between time to rise from the floor and 6MWT at baseline was high (r = 0.6, p<0.01).Both time to rise from the floor and baseline 6MWT were relevant for predicting 6MWT changes in the group above the age of 7 years, with no interaction between the two measures, as the impact of time to rise from the floor on 6MWT change was similar in the patients below and above 350 m. Our results suggest that, time to rise from the floor can be considered an additional important prognostic factor of 12 month changes on the 6MWT and, more generally, of disease progression

Future making and visual artefacts : an ethnographic study of a design project

Current research on strategizing and organizing has explored how practitioners make sense of an uncertain future, but provides limited explanations of how they actually make a realizable course of action for the future. A focus on making rather than sensemaking brings into view the visual artefacts that practitioners use in giving form to what is ‘not yet’ – drawings, models and sketches. We explore how visual artefacts are used in making a realizable course of action, by analysing ethnographic data from an architectural studio designing a development strategy for their client. We document how visual artefacts become enrolled in practices of imagining, testing, stabilizing and reifying, through which abstract imaginings of the future are turned into a realizable course of action. We then elaborate on higher-order findings that are generalizable to a wide range of organizational settings, and discuss their implications for future research in strategizing and organizing. This paper contributes in two ways: first, it offers future making as an alternative perspective on how practitioners orient themselves towards the future (different from current perspectives such as foreseeing, future perfect thinking and wayfinding). Second, it advances our understanding of visual artefacts and their performativity in the making of organizational futures
