This paper is an output of a two day 'Festival Lab' held at the Future Everything Festival, Manchester, UK, March 2015. The Festival Lab invited a team of academic researchers to develop a model of public engagement during the festival that would explore specific research questions around mobility, data awareness, and civic engagement. From this brief the academic team developed the Festival Lab 'PuBLiC', and created an activity arc that involved participants borrowing bicycles and responding to structured and unstructured research questions about the future of cycling and data use in the city of Manchester. Equipped with iPhones with bespoke software for collecting short textual comments, photographs and GPS data, participants became integral actors in one-day field studies, taking the role of both subjects and authors of this paper. We present findings and observations noted by participants and researchers, discussing the significance of these as triangulated in a closing workshop plenary session. Finally, we conclude by reflecting on the paper creation process itself, a collaborative, intensive, fast-paced approach that challenges the very framework of academic authority and public engagement. © 2015 ACM.

Medical professionals and indeed the general public have an increasing interest in the acquisition of dermatoscopic images of suspect or ambiguous skin lesions. To this end, good dermatoscopic image quality and low costs are important considerations.Images of seven lesions (seborrheic keratosis, melanoma in-situ, blue and dermal nevus, basal cell carcinoma and two squamous cell carcinomas) were taken. A novel technique of tape dermatoscopy involved: Using immersion fluid (i.e., water, olive oil, disinfectant spray) placed on the flat or slightly elevated lesion;Covering the lesion with transparent adhesive tape with lateral tension;Using ambient indoor or outdoor lighting for illumination (rather than flash photography);Positioning a photographic device at an angle of approximately 45 from the side of the lesion to avoid light reflection;Recording a focused image with a mobile phone or digital camera at a distance of approximately 25-30 cm from the lesion; andEnlarging the image on the screen of the device. Essential dermatoscopic features enabling a correct diagnosis were visible in 6 of the 7 lesions. Tape dermatoscopy images of the lesions were compared to standard dermatoscopy (using a Fotofinder handyscope in combination with a mobile phone). The latter confirmed the dermatoscopic features in six of seven lesions.Tape dermatoscopy images can be recorded by medical personnel and even the general public without a dermatoscope. However, the limitations of this method are that images may be unfocused, exophytic tumors may be difficult to assess, excess pressure on tumoral blood vessels may lead to compression artefact, dermatoscopic features that are only visible under polarized light are unable to be detected (particularly crystalline or chrysalis structures) and tumors in certain anatomic locations may be difficult to assess (e.g., edges of nose, ears [demonstrated in one case], nails). Comparative prospective studies are necessary in order to test reproducibility of these preliminary findings, to establish special indications for the technique, and to develop guidelines for its effective use.
