This work investigates the connection among optical aspects of photographic composition and the quality, perception and interpretation of the level of realism of images. Therefore, to investigate this connection, an experiment was carried out in two steps: The first step consisted of performing analyzes of the optical or photographic contrasts of previously selected images. The second step was the elaboration of a questionnaire with 19 images selected in the first step, aiming to collect data about the perception and opinion of the users. Finally, the objective data from the first step was crossed with the subjective data from the second. The conclusion indicates evidence of the connection or convergence between images that obey the principles of photographic composition that are perceived as having better realism by the users. It is plausible to consider the importance of photo-graphic theory to image design for the users perceive the images as more realistic.

The knowledge base for Social Work is strengthening. Underpinning of Social Work deriving from scientific research is necessary given the growing complexity of the work and its context. How this research should be conducted and to what type of outcomes it must lead, is part of an ongoing debate. In the Netherlands, practice-based research at Universities of Applied Sciences (UAS) is a relative new approach. Social Work research groups at UAS assert to conduct practice-based research in order to contribute to knowledge and support the objectives of Social Work. The current study was carried out to obtain insight into the characteristics of this research approach. A sample of publications was analysed in terms of knowledge purpose, methodology, and level and type of participation. Results show a strong focus on producing descriptive knowledge and to a lesser extent on control knowledge, using primarily qualitative research methods, and with limited direct participation by stakeholders. In order to practice more what they preach the research can strengthen by doing more empirical research, by diversifying the research in terms of design and methods and increasing the level of participation of stakeholders

This publication gives an account of the Public Annotation of Cultural Heritage research project (PACE) conducted at the Crossmedialab. The project was carried out between 1 January 2008 and 31 December 2009, and was funded by the Ministry of Education, Culture, and Science. Three members of the Dutch Association of Science Centres (Vereniging Science Centra) actively participated in the execution of the project: the Utrecht University Museum, the National Museum of Natural History (Naturalis), and Museon. In addition, two more knowledge institutes participated: Novay and the Utrecht University of Applied Sciences. BMC Consultancy and Manage¬ment also took part in the project. This broad consortium has enabled us to base the project on both knowledge and experience from a practical and scientific perspective. The purpose of the PACE project was to examine the ways in which social tagging could be deployed as a tool to enrich collections, improve their acces¬sibility and to increase visitor group involvement. The museums’ guiding question for the project was: ‘When is it useful to deploy social tagging as a tool for the benefit of museums and what kind of effect can be expected from such deployment?’ For the Crossmedialab the PACE project presented a unique opportunity to conduct concrete research into the highly interesting phenomenon of social tagging with parties and experts in the field.

Camera trap technology has galvanized the study of predator-prey ecology in wild animal communities by expanding the scale and diversity of predator-prey interactions that can be analyzed. While observational data from systematic camera arrays have informed inferences on the spatiotemporal outcomes of predator-prey interactions, the capacity for observational studies to identify mechanistic drivers of species interactions is limited. Experimental study designs that utilize camera traps uniquely allow for testing hypothesized mechanisms that drive predator and prey behavior, incorporating environmental realism not possible in the lab while benefiting from the distinct capacity of camera traps to generate large data sets from multiple species with minimal observer interference. However, such pairings of camera traps with experimental methods remain underutilized. We review recent advances in the experimental application of camera traps to investigate fundamental mechanisms underlying predator-prey ecology and present a conceptual guide for designing experimental camera trap studies. Only 9% of camera trap studies on predator-prey ecology in our review mention experimental methods, but the application of experimental approaches is increasing. To illustrate the utility of camera trap-based experiments using a case study, we propose a study design that integrates observational and experimental techniques to test a perennial question in predator-prey ecology: how prey balance foraging and safety, as formalized by the risk allocation hypothesis. We discuss applications of camera trap-based experiments to evaluate the diversity of anthropogenic influences on wildlife communities globally. Finally, we review challenges to conducting experimental camera trap studies. Experimental camera trap studies have already begun to play an important role in understanding the predator-prey ecology of free-living animals, and such methods will become increasingly critical to quantifying drivers of community interactions in a rapidly changing world. We recommend increased application of experimental methods in the study of predator and prey responses to humans, synanthropic and invasive species, and other anthropogenic disturbances.

In Social Work research there is a strong debate on the distinctiveness and methodological quality, and how to address the dilemma of rigour and practice relevance. Given the nature of Social Work the field has developed a characteristic research culture that puts emphasis on giving voice to service users and disseminating research knowledge in practice, especially in a stream of so called practice-based research. However, there is no consensus on how to best contribute to the practice of Social Work through research and at the same time producing rigourous scientific outcomes, resulting in methodological pluralism. Studying the perceptions of Social Work researchers on their role, the aims and values of Social Work research and their research approach, provides insight into the methodological pluralism of Social Work research. Thirty-four professors specialising in practice-based Social Work research participated in a Q methodology study. Q methodology combines qualitative and quantitative methods. It helped reveal and describe divergent views as well as consensus. The analysis led to the identification of three differing viewpoints on Social Work research, which have been given the following denominators: The Substantiator, The Change Agent and The Enlightener. The viewpoints provide researchers in the field of Social Work with a framework in which they can position themselves in the methodological pluralism. Researchers state that the viewpoints are helpful in clarifying perspectives on good research, facilitate the discourse on methodological choices to further develop and strengthen Social Work research as a scientific discipline

Audience studies is not the vibrant field it was in its 1980s and early 1990s heyday. Cultural studies today has a more balanced interest in production, audiences and texts. A renewed focus in audience studies on everyday meaning production, identity and relations of power could benefit from recent developments. Theorization of power especially has benefited from recent work on governmentality. In accord with recent work on ‘affect’, there is an opportunity for renewed vitality and urgency. Was audience studies damaged beyond repair by the charge that it is a populist field that celebrates rather than interrogates everyday media culture? Could a concept such as cultural literacy provide a bridge to help re-establish the critical credibility of audience studies or would it burden this field with its implied notions of standards, distinction and cultural exclusion? The article discusses recent work with youth audiences to inquire into the possibilities of ‘critical literacy’. It proposes taking up questions and insights raised by affect theory, to merge appreciation, criticism and understanding of the forces that drive (the possibility of) change, and to embed critical literacy in cultural studies’ ongoing interest in the construction of (cultural) citizenship.
