Studying images in social media poses specific methodological challenges, which in turn have directed scholarly attention towards the computational interpretation of visual data. When analyzing large numbers of images, both traditional content analysis as well as cultural analytics have proven valuable. However, these techniques do not take into account the circulation and contextualization of images within a socio-technical environment. As the meaning of social media images is co-created by networked publics, bound through networked practices, these visuals should be analyzed on the level of their networked contextualization. Although machine vision is increasingly adept at recognizing faces and features, its performance in grasping the meaning of social media images is limited. However, combining automated analyses of images - broken down by their compositional elements - with repurposing platform data opens up the possibility to study images in the context of their resonance within and across online discursive spaces. This paper explores the capacities of platform data - hashtag modularity and retweet counts - to complement the automated assessment of social media images; doing justice to both the visual elements of an image and the contextual elements encoded by networked publics that co-create meaning.

Background: Auditory processing disorder (APD) is a diagnosis that is widely discussed. Children diagnosed with APD have difficulty listening in complex situations, despite a well-functioning peripheral hearing. However, there seems to be no evidence for the validity of a purely auditory deficit. The aim of this study is to examine the differences in performance between children with suspected APD and typically developing children on tests of communication, auditory processing, nonverbal intelligence, working memory, and visual and auditory attention. Methods: In a case-control study we examined 9 children with suspected APD and 21 typically developing children, ages 8;0 to 12;0 years. The parents of all children completed three questionnaires about history, behavioral symptoms of ADHD, and communication skills. The teachers of the children completed the Children’s Auditory Processing Performance Scale (CHAPPS). The children themselves were assessed for auditory processing abilities, nonverbal intelligence, working memory, and auditory and visual attention. Results: No differences were found between groups in age, nonverbal intelligence quotient, and performance on auditory processing tests. Children with suspected APD have significantly poorer communication performance (parent report), poorer listening skills (teacher report), poorer working memory and poorer auditory and visual skills. Conclusion: There is a difference between children with suspected APD and typically developing children. Children with suspected APD perform insufficient on tests of working memory, and have a slower response to auditory and visual attention tasks. Parents of children with suspected APD report difficulties in communication and teachers assess the children of being at risk for listening difficulties.

Vertical urbanisation is perceived as necessary to accommodate a growing population but is associated with severe risks for human well-being. It requires a profound understanding of how archi-tectural designs can ensure visually readable and liveable environments before it has been built. How-ever, current digital representation techniques fail to address the diverse interests of non-experts. Emerging biometric technologies may deliver the missing user information to involve (future) inhabit-ants at different stages of the planning process. The study aims to gain insight into how non-experts (visually) experience 3D city visualizations of designed urban areas. In two laboratory studies, univer-sity students were randomly assigned to view a set of the same level of detail images from one of two planned urban area developments in the Netherlands. Using eye-tracking technology, the visual behav-iour metrics of fixation count and duration and general eye-movement patterns were recorded for each image, followed by a short survey. The results show how visual behaviour and perception are remark-ably similar across different detail levels, implying that 3D visualizations of planned urban develop-ments can be examined by non-experts much earlier in the design process than previously thought.

Over the next 10 years, the City of Amsterdam plans to develop major housing schemes provide 90,000 new homes within the existing urban fabric. At the same time, an urban renewal program is being launched to revitalize the most deprived neighbourhoods. Together, these challenges call for more evidence based designprinciples to secure liveable places. Recent development in neuroscience, provides innovative tools to examine in a measurable, cause-effect way, the relationships between the physical fabric, users’ (visual) experience and their behavior in public spaces. In neuroscience, eye-tracking technology (ET) complements brain and behavioral measures (for overview see Eckstein et al. 2017). ET is already used to evaluate the spatial orienting of attention, behavioral response and emotional and cognitive impact in neuroscience, psychology and market research (Popa et al. 2015). ET may also radically change the way we (re)design and thus, experience cities (Sita et al. 2016; Andreani 2017). Until now, eye-tracking pilot studies collected eye fixation patterns of architecture using images in a lab-setting (Lebrun 2016).In our research project Sensing Streetscapes, we take eye-tracking outdoors and explore the potential ET may offer for city design. In collaboration with the municipality of Amsterdam and the local community, the H-neighborhood is used as a single case study. The main focus for urban renewal lies in the “transition-spaces”. They connect the neighborhood with the rapidly developing adjacent areas and are vital for improving the weak social-economic status. The commonly used design principles are validated (Alexander et al. 1977; Gehl 2011, 2014; Pallasmaa 2012) and the consistency of ET is tested, alongside (walk along) interviews and behavioral observations. In the next phase, the data will be analyzed by a panel of applied psychologists and urban designers. The initial results provide valuable lessons for the use of eye-tracking in urban design research. For example, a visual pattern analysis offers more accurate images of the spatial key-elements that matter when moving through transition spaces. More sensory-based city design research is needed to gather a full understanding of the relationships between the configuration of space, users’ (visual) experience, behavioral responses and in turn, perceptual decision making.

The aim of the current study was twofold: (1) to validate the use of action sport cameras for quantifying focus of visual attention in sailing and (2) to apply this method to examine whether an external focus of attention is associated with better performance in upwind sailing. To test the validity of this novel quantification method, we first calculated the agreement between gaze location measures and head orientation measures in 13 sailors sailing upwind during training regattas using a head mounted eye tracker. The results confirmed that for measuring visual focus of attention in upwind sailing, the agreement for the two measures was high (intraclass correlation coefficient (ICC) = 0.97) and the 95% limits of agreement were acceptable (between -8.0% and 14.6%). In a next step, we quantified the focus of visual attention in sailing upwind as fast as possible by means of an action sport camera. We captured sailing performance, operationalised as boat speed in the direction of the wind, and environmental conditions using a GPS, compass and wind meter. Four trials, each lasting 1 min, were analysed for 15 sailors each, resulting in a total of 30 upwind speed trials on port tack and 30 upwind speed trials on starboard tack. The results revealed that in sailing - within constantly changing environments - the focus of attention is not a significant predictor for better upwind sailing performances. This implicates that neither external nor internal foci of attention was per se correlated with better performances. Rather, relatively large interindividual differences seem to indicate that different visual attention strategies can lead to similar performance outcomes.

Purpose - The purpose of this paper is to develop a research model to investigate corporate visual identity (CVI) management from an organisational perspective. It is assumed that characteristics of the organisation and of the way a CVI is managed will affect consistency of CVI. Design/methodology/approach - The model was tested in a survey carried out among employees in 20 Dutch organisations. Structural equation modelling with AMOS was conducted to get insight into the various influences and relationships. Findings - CVI management characteristics - socialisation processes related to CVI, knowledge of CVI strategy, and CVI tools and support - have a strong impact on the consistency of CVI, and organisational characteristics affect the way CVI is managed. With the exception of the openness and dynamics of an organisation, no supporting evidence was found for a direct relationship between organisational characteristics and CVI consistency. Research limitations/implications - CVI has been measured by the judgement of the respondents, all employees of the organisation concerned. Therefore the measure was the perceived consistency of CVI. Further research could include a visual audit and the perception of external stakeholders towards the visual identity. There was no distinction examined among the main corporate visual identity and sub- or product brands. The study was conducted in the Netherlands, where the Dutch term huisstijl is unambiguous and clearly related to the corporate brand or identity. Future research can take different brands into account or can broaden the concept of CVI (including cultural aspects, language, rituals, myths, etc.). Practical implications - The results indicate that CVI management matters, that CVI management is related to more general organisational characteristics, but that communication managers nevertheless have a considerable amount of freedom in determining the way they manage their CVI. Originality/value - Corporate visual identity has received little attention in research and hardly been studied at all from the perspective of this paper. This paper has value to both researchers in the fields of corporate identity and organisational identity, as well as professionals involved in managing the corporate identity. © Emerald Group Publishing Limited.

The concept of biodiversity, which usually serves as a shorthand to refer to the diversity of life on Earth at different levels (ecosystems, species, genes), was coined in the 1980s by conservation biologists worried over the degradation of ecosystems and the loss of species, and willing to make a case for the protection of nature – while avoiding this “politically loaded” term (Takacs, 1996). Since then, the concept has been embedded in the work of the Convention on Biological Diversity (CBD, established in 1992) and of the Intergovernmental science-policy Platform on Biodiversity and Ecosystem Services (IPBES, aka ‘the IPCC for biodiversity’, established in 2012). While the concept has gained policy traction, it is still unclear to which extent it has captured the public imagination. Biodiversity loss has not triggered the same amount of attention or controversy as climate change globally (with some exceptions). This project, titled Prompting for biodiversity, investigates how this issue is mediated by generative visual AI, directing attention to both how ‘biodiversity’ is known and imagined by AI and to how this may shape public ideas around biodiversity loss and living with other species.

Studying images on social media introduces several challenges that relate to the size of datasets and the different meaning-making grammars of social visuality; or as aptly pointed out by others in the field, it means ‘studying the qualitative on a quantitative scale’. Although cultural analytics provides an automated process through which patterns can be detected in large numbers of images, this methodology doesn’t account for other modalities of the image than the image itself. However, images circulating social media can (and should) be analyzed on the level of their audience as the latter is co-creating the meaning of images. Bridging the study of platform affordances and affect theory, this paper presents a novel methodology that repurposes Facebook Reactions to infer collective attitudes and performative emotional expressions vis á vis images shared on the large Syrian Revolution Network public page (+2M). We found visual patterns that co-occur with certain collective combinations of buttons, displaying how socio-technical features shape the discursive frameworks of online publics.

This paper will discuss the process of the MA program ePedagogy / Visual Knowledge Building during the first semester of the academic year 2005 – 2006. This MA program is a joint venture between the Universities of Helsinki, Hamburg and INHOLLAND. This publication will discuss and evaluate the concrete steps (in terms of learning process) during this first semester. In particular the role of the eTutor will get special attention. This publication is based on the principle of action research. Hart & Bond defines action research as “it is a form of reflective inquiry which enables practitioners to better realise such qualities in their practice. The tests for good action research are very pragmatic ones. Does it improve the professional quality of the transactions between practitioners and clients/colleagues? This action research approach is being realised upon three main sources. As an eTutor and member of the staff of this program I weekly filled in an “Evaluation Log” in which the following questions are centralized: 1. What happened (this week) 2. Significant experience 3. Reflection 4. Actions Secondly I used a little survey which was being used by the staff to evaluate the first semester. All the three Universities filled in a form with the following questions concerning the education and organisation: Education 1. What do you consider most hindering in your teaching? 2. What do you consider most beneficial in your teaching? 3. What kind of teaching methods do you prefer in this program? 4. Do you think the course offers are attractive for the target group? 5. How do you evaluate student’s engagements and motivation in your courses? 6. What can / should be improved in terms of collaborative learning activities and processes? Organisation 1. In what specific context do you spot organisational constraints? 2. Does your organisation recognise and support the MA program? 3. What is your short-, mid- and long term vision on this program? Thirdly an important source for this action research approach was the International Seminar which was hold in the middle of February 2006. In this seminar the changes based on the questions of the questionnaire were discussed and implemented. The theoretical framework in this publication is based on the dissertation of Karel Kreijns (Sociable CSCL Environments). In this dissertation he discussed the collaborative cognitiveand epistemic performance in a CSCLE. The social presence theory takes a central position in this dissertation. In this paper the pitfalls and barriers concerning a sociable CSCLE are being discussed and evaluated. This paper describes, the interventions the staff took, in order to improve the educational context of the program. From this perspective we looked very carefully to the barriers and pitfalls in our Virtual Learning Environment (VLE). We found evidence for the fact that a good CSCLE consists at least a good balance between Content, Community and Pedagogy. In the program we emphasised our focus (too much) on content and (too) little on community and pedagogy. The community was poor because of the fact that we used three content learning systems, which didn’t stimulate the group processes. Pedagogy was too much based on individual eTutor behaviour. In January 2006, after the courses were ended, the Universities organised a little survey. In this survey was shown that we have to some interventions to improve the learning process. At the International Seminar in February 2006 eTutors and students discussed the problems. The following interventions are being considered and implemented: 1. The use of three Virtual Learning Environments should be decreased. Especially the INHOLLAND / Blackboard system doesn’t reflect the open source philosophy. Besides this the accessibility of this system is not very easy for foreign students 2. The collaborative aspect should be increased, by emphasising the interdisciplinaryand international co-operation. The formation of international subgroups is implemented.
