    From analogue to digital scholarship: implications for science communication researchers

    Digital media have transformed the social practices of science communication. They have extended the number of channels that scientists, media professionals, other stakeholders and citizens use to communicate scientific information. Social media provide opportunities to communicate in more immediate and informal ways, while digital technologies have the potential to make the various processes of research more visible in the public sphere. Some digital media also offer, on occasion, opportunities for interaction and engagement. Similarly, ideas about public engagement are shifting and extending social practices, partially influencing governance strategies, and science communication policies and practices. In this paper I explore this developing context via a personal journey from an analogue to a digital scholar. In so doing, I discuss some of the demands that a globalised digital landscape introduces for science communication researchers and document some of the skills and competencies required to be a digital scholar of science communication

    Supporting excellence in engaged research

    This paper reviews the purposes, definitions and criteria designed to embed ‘engaged research’ as a strategic priority with universities, and explores some of the challenges of implementation. Surveys of academics have shown various understandings of, and attitudes to, the practices of engaged research, but also impediments to realising the aspirations it expresses. Drawing on the experience as the academic lead for engaged research at the Open University, the author explores questions of professionalisation, for example, through training, support mechanisms and measures of recognition for engaged research. He concludes by arguing that, if done well, engaged research can promote epistemic justice

    Evaluating methods for controlling depth perception in stereoscopic cinematography.

    Existing stereoscopic imaging algorithms can create static stereoscopic images with perceived depth control function to ensure a compelling 3D viewing experience without visual discomfort. However, current algorithms do not normally support standard Cinematic Storytelling techniques. These techniques, such as object movement, camera motion, and zooming, can result in dynamic scene depth change within and between a series of frames (shots) in stereoscopic cinematography. In this study, we empirically evaluate the following three types of stereoscopic imaging approaches that aim to address this problem. (1) Real-Eye Configuration: set camera separation equal to the nominal human eye interpupillary distance. The perceived depth on the display is identical to the scene depth without any distortion. (2) Mapping Algorithm: map the scene depth to a predefined range on the display to avoid excessive perceived depth. A new method that dynamically adjusts the depth mapping from scene space to display space is presented in addition to an existing fixed depth mapping method. (3) Depth of Field Simulation: apply Depth of Field (DOF) blur effect to stereoscopic images. Only objects that are inside the DOF are viewed in full sharpness. Objects that are far away from the focus plane are blurred. We performed a human-based trial using the ITU-R BT.500-11 Recommendation to compare the depth quality of stereoscopic video sequences generated by the above-mentioned imaging methods. Our results indicate that viewers' practical 3D viewing volumes are different for individual stereoscopic displays and viewers can cope with much larger perceived depth range in viewing stereoscopic cinematography in comparison to static stereoscopic images. Our new dynamic depth mapping method does have an advantage over the fixed depth mapping method in controlling stereo depth perception. The DOF blur effect does not provide the expected improvement for perceived depth quality control in 3D cinematography. We anticipate the results will be of particular interest to 3D filmmaking and real time computer games

    An analysis of marketing programmes adopted by regional small and medium-sized enterprises

    Originality/value – Their ability to understand their marketplace and to become truly competitive relies on SMEs developing a deeper understanding of their current marketing decision-making processes through the systematic adoption of more robust strategic procedures. In summary, there is an observable difference between marketing activities conducted by SMEs and best practice defined in academic theory.Purpose – The purpose of this paper is to create an understanding of the true nature of contemporary SME marketing activities. While acknowledging operational constraints, the paper aims to hypothesize that, if effective marketing planning was employed, this would improve the long-term growth of small to medium-sized enterprises. The paper seeks to assess the implications current practices may have on the long-term survival of enterprises and to identify significant SME marketing development and training needs. Design/methodology/approach – A marketing audit approach yielded data from the collation of 125 completed online questionnaires within the East of England region. Statistical analysis using SPSS was applied to produce an in-depth quantitative analysis of these data. In addition, qualitative data were collected through face-to-face interviews of some 20 owner-managers. These responses were further inductively analysed and interpreted. Findings – Data analysis demonstrated a significant disparity between their perceived marketing effectiveness compared with their actual practices recorded at interview. Significantly, they failed to understand why campaigns did not yield results, as they routinely did not employ appropriate controls and procedures. SMEs believed that they were fully cognisant of the effectiveness of their marketing activity, through further exploration; evidence revealed that they failed to employ sufficient review procedures, and in the extreme cases these procedures were non-existent. A direct correlation was also witnessed between company size and the application of effective marketing planning. Larger enterprises demonstrated a greater awareness of strategic marketing competence

    An application driven comparison of depth perception on desktop 3D displays.

    Desktop 3D displays vary in their optical design and this results in a significant variation in the way in which stereo images are physically displayed on different 3D displays. When precise depth judgements need to be made these differences may become critical to task performance. Applications where this is a particular issue include medical imaging, geoscience and scientific visualization. We investigate perceived depth thresholds for four classes of desktop 3D display; full resolution, row interleaved, column interleaved and colour-column interleaved. Given the same input image resolution we calculate the physical view resolution for each class of display to geometrically predict its minimum perceived depth threshold. To verify our geometric predictions we present the design of a task where viewers are required to judge which of two neighboring squares lies in front of the other. We report results from a trial using this task where participants are randomly asked to judge whether they can perceive one of four levels of image disparity (0,2,4 and 6 pixels) on seven different desktop 3D displays. The results show a strong effect and the task produces reliable results that are sensitive to display differences. However, we conclude that depth judgement performance cannot always be predicted from display geometry alone. Other system factors, including software drivers, electronic interfaces, and individual participant differences must also be considered when choosing a 3D display to make critical depth judgements
