This paper aims to enrich the current understanding of data curation prevalent in e-Science by drawing on an ethnographic study of one of the longest-running efforts at longterm consistent data collection with open data sharing in an environment of interdisciplinary collaboration. In such a context we identify a set of salient characteristics of ecological research and data that shape the data stewardship approach of the Long Term Ecological Research (LTER) network. We describe the actual practices through which LTER information managers attend to the extended temporal scale of long-term research and data sets both through data care work and information infrastructure development. We discuss the issues of long-term and continuity that represent central challenges for data curation and stewardship. We argue for more efforts to be directed to understanding what is at stake with a long-term perspective and differing temporal scales as well as to studying actual practices of data curation and stewardship in order to provide more coherent understandings of e-Science solutions and technologies.

Abstract. Children's participation in information and communication technology (ICT) design is an established interdisciplinary research field. Methods for children's participation have been developed, but a closer link between theory and design has been called for, as well as an examination of various participants influencing children's participation in ICT design. This paper addresses these gaps by introducing the research strategy of nexus analysis as a promising theoretical framework. Especially the concepts of 'interaction order' and 'historical body' are utilized in the analysis of six empirical studies on ICT design with children. The analysis shows that through the participating children there were also 'others' involved, multiple voices to be heard, often invisible but informing design. Some of these 'others' have already been acknowledged in literature but the issue has not been examined in depth and common vocabulary for this is lacking. Some practical implications will be offered by illustrating how to consider these concepts in different phases of ICT design: when establishing relationships with children, involving children as participant designers, and analysing the results of these participative processes.

The cooperative design practices as well as the participatory research tradition and contextual design have inspired the researchers of a relatively new and challenging design context, i.e. design with children for children. An ample literature base of its own has been generated on the subject already. However, the phenomenon of children imitating each other"s work in the design sessions has been largely disregarded in current research. This article sheds light on the practices of "recycling", originally characterised as "imitation", in the drawings produced by children during participatory design workshops in a school setting. The article suggests that instead of ignoring the issue of imitation and recycling, practitioners might start to appreciate it; both when planning design sessions as well as when making interpretations and judgments on the basis of the results produced by children. Implications for practice and future research are discussed.

This study discusses measurement of well-being in the context of smart environments. We propose an experimental design which induces variation in an individual's flow, stress, and affect for testing different measurement methods. Both qualitative and quantitative measuring methods are applied, with a variety of wearable sensors (EEG sensor, smart ring, heart rate monitor) and video monitoring. Preliminary results show significant agreement with the test structure in the readings of wearable stress and heart rate sensors. Selfassessments, on the contrary, fail to show significant evidence of the experiment structure, reflecting the difficulty of subjective estimation of short-term stress, flow and affect.

The aim of this study is to contribute to the understanding of Information Literacy (IL) in relation to knowledge creation in organizational settings. IL is understood as a practice realized in the course of action, emphasizing the social and interactive aspects of the phenomenon. There is a need to increase understanding of the role of IL in knowledge processes and develop methods for empirical examination. We suggest an approach for examining IL in knowledge creation and present results of a qualitative study on interaction in a multidisciplinary research consortium. The findings suggest that knowledge creation relates to the abilities of using various sources of information and understanding the relevance of the suggested information in the discussions. The outcomes can be used in developing the methods of examining IL and in enhancing abilities to create new knowledge and collaborate in organizations.
