During crime scene investigations, numerous traces are secured and may be used as evidence for the evaluation of source and/or activity level propositions. The rapid chemical analysis of a biological trace enables the identification of body fluids and can provide significant donor profiling information, including age, sex, drug abuse, and lifestyle. Such information can be used to provide new leads, exclude from, or restrict the list of possible suspects during the investigative phase. This paper reviews the state-of-the-art labelling techniques to identify the most suitable visual enhancer to be implemented in a lateral flow immunoassay setup for the purpose of trace identification and/or donor profiling. Upon comparison, and with reference to the strengths and limitations of each label, the simplistic one-step analysis of noncompetitive lateral flow immunoassay (LFA) together with the implementation of carbon nanoparticles (CNPs) as visual enhancers is proposed for a sensitive, accurate, and reproducible in situ trace analysis. This approach is versatile and stable over different environmental conditions and external stimuli. The findings of the present comparative analysis may have important implications for future forensic practice. The selection of an appropriate enhancer is crucial for a well-designed LFA that can be implemented at the crime scene for a time- and cost-efficient investigation.

The visual representation of Information System (IS) artefacts is an important aspect in the practical application of visual representations. However, important and known visual representation principles are often undervalued, which could lead to decreased effectiveness in using a visual representation. Decision Management (DM) is one field of study in which stakeholders must be able to utilize visual notations to model business decisions and underlying business logic, which are executed by machines, thus are IS artefacts. Although many DM notations currently exist, little research actually evaluates visual representation principles to identify the visual notations most suitable for stakeholders. In this paper, the Physics of Notations framework of Moody is operationalized and utilized to evaluate five different DM visual notations. The results show several points of improvement with regards to these visual notations. Furthermore, the results could show the authors of DM visual notations that well-known visual representation principles need to be adequately taken into account when defining or modifying DM visual notations.

Older adults experience visual problems owing to biological ageing or eye disease. In the Netherlands, the prevalence of visual impairments is the highest in the subgroup of nursing home residents (41.3%). These impairments influence quality of life in terms of limiting daily activities and participation in social activities. Furthermore, 63% of visual problems are defined as ‘avoidable blindness’. For this reason, screening of visual functioning in the nursing home is of major importance. Moreover, visual functioning should also be taken into account to prevent the incidence of falls.

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.

Background: While the participation of adults with visual and severe or profound intellectual disabilities (VSPID) in society and community life is important, evidence-based interventions to improve their participation are lacking. Weconducted a process evaluation of the implementation of ‘Care for Participation+’ (CFP+), a new intervention targeting the attitudes of direct support professionals (DSPs) toward the participation of adults with VSPID, within a residential facility in the Netherlands.Methods: CFP+ was inspired by the Boston Psychiatric Rehabilitation Approach and adapted by adopting a new definition and operationalization of the concept of participation for adults with VSPID. Following systematic training, 16 DSPs of adults with VSPID were able to apply key elements of CFP+ to explore diverse roles and activities for this population, facilitating their self-management, teaching them necessary skills for participation, and organizing support. Our process evaluation entailed an investigation of the delivered dose, reach, fidelity, and adaptation of CFP+ during and after the CFP+ intervention. We also evaluated the mechanisms of impact and context using questionnaires, assignments, documentation, interviews, and a logbook.Results: The intended dose, reach, and fidelity relating to the implementation of CFP+ were not achieved. Despite this fact, an assessment of the mechanisms of impact indicated that assignments of CFP+ were well (75%) or reasonably well (17%) understood by DSPs. CFP+ was applied by DSPs to stimulate self-management (83% of DSPs), new activities (100%), enhanced involvement in existing activities (67%) and to explore new roles (50%) for adults with VSPID. A negative contextual factor mentioned by the trainer and manager was the DSPs’ lack of commitment to the training program. Another negative contextual factor mentioned by DSPs was the lack of time for implementing CFP+.Conclusions: CFP+ provides new opportunities to improve the participation of adults with VSPID. Despite the nonoptimal conditions for implementing CFP+ and the DSPs’ general reluctance to apply the new intervention, some have actively used CFP+ within the residential facility. Future studies should focus on the outcomes of CFP+ regarding attitudinal changes among DSPs relating to the participation of adults with VSPID and their quality of life.

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.

People in western countries spend approximately 90% of their time indoors. This severely affects their health (WHO 2013; Klepeis et al. 2001). The health risks are exacerbated if people travel between indoor spaces by car or public transport. Buildings on streets specifically designed to create a human scale and connected with the street-space can potentially invite people to walk and enhance their engagement with their surroundings (O’Mara 2019; Ewing et al. 2013). Since the 1960s, influential empirical studies have raised awareness of the walkability of streets (e.g. Jacobs 2008) but reliable evidence on the effectiveness of applied design solutions remains scarce (Spanjar & Suurenbroek 2020). This eye-tracking study focused on the visual ‘scanning’ of streetscapes and people’s appreciation of applied design principles. The aim was to gather together lessons learned from a variety of streetscapes in cities around the world and use them to inform the design of new developments in the Netherlands. Google Street View was used to select 19 images of streets in high-density environments with human-scale attributes in their façades and street-spaces. They were presented in a randomized order in a laboratory setting to 40 participants, who viewed them for 5 seconds. The participants’ visual explorative behaviour was recorded with advanced eye-tracking technology. A survey recorded their overall appreciation of the scenes and mouse-tracking collated their specific areas of interest (see fig. 1). The comparative analysis of the participants’ aggregated eye-fixation images together with the supplementary methods suggests that certain attributes for creating a human scale catch the eye in the first few seconds and are highly appreciated. These include the variety of a street’s façades, a street’s enclosedness, and the level of detail in the transition zone between the private ground floor and the public street (see fig. 2). Green features are particularly valued and might have important restorative qualities for people who spend most of their time indoors (Kaplan 1995; Ulrich 1984). Future research should focus on the design of façades and the street-space itself, taking people’s indoor lives and related stress levels as a starting point.

For environmental governance to be more effective and transformative, it needs to enhance the presence of experimental and innovative approaches for participation. This enhancement requires a transformation of environmental governance, as too often the (public) participation process is set up as a formal obligation in the development of a proposed intervention. This article, in search of alternatives, and in support of this transformation elaborates on spaces where participatory and deliberative governance processes have been deployed. Experiences with two mediated participation methodologies – community art and visual problem appraisal – allow a demonstration of their potential, relevance and attractiveness. Additionally, the article analyzes the challenges that result from the nature of these arts-based methodologies, from the confrontational aspects of voices overlooked in conventional approaches, and from the need to rethink professionals’ competences. Considering current environmental urgencies, mediated participation and social imaginaries still demonstrate capacities to open new avenues for action and reflection.
