The purpose of this book is to open a conversation on the idea of information experience, which we understand to be a complex, multidimensional engagement with information. In developing the book we invited colleagues to propose a chapter on any aspect of information experience, for example conceptual, methodological or empirical. We invited them to express their interpretation of information experience, to contribute to the development of this concept. The book has thus become a vehicle for interested researchers and practitioners to explore their thinking around information experience, including relationships between information experience, learning experience, user experience and similar constructs. It represents a collective awareness of information experience in contemporary research and practice. Through this sharing of multiple perspectives, our insights into possible ways of interpreting information experience, and its relationship to other concepts in information research and practice, is enhanced. In this chapter, we introduce the idea of information experience. We also outline the book and its chapters, and bring together some emerging alternative views and approaches to this important idea.

Introduction: The role of commercial sex in facilitating infection transmission is a subject of ongoing empirical enquiry, with little attention to the variety and extent of ‘non-traditional’ commercial services that pose a lesser risk of infection. This study sought to examine the supply and demand of a wide range of traditional and non-traditional commercial sexual services among sex workers and their clients from Queensland, Australia. Methods: Cross-sectional convenience sampling was used to compare female sex workers in 1991 (n=200, aged 16-46 years) and 2003 (n=247, aged 18-57 years) and from male clients in 2003. The client sample comprised 160 male clients aged between 19 and 72 years. Results: Over the comparison period there was a significant increase in the provision of ‘exotic’ or non-traditional sexual services. In 2003, the availability of bondage and discipline, submission, fantasy, use of sex toys, golden showers, fisting and lesbian double acts had increased dramatically, while ‘traditional’ services had mostly remained at similar levels. Moreover, the proportion of sex workers in some industry sectors providing ‘exotic’ commercial services seem to have risen over time. Conclusion: Undoubtedly, the sex industry has professionalised and now includes more sophisticated and specialized suppliers. As with any commercial business, the diversification of services is largely driven with client demand, with the ‘menu’ being generally broader than the majority of client preferences. However, although clients demands for particular commercial sexual services seems to have been met, with regard to anal sex and anal play, supply has failed to meet client demand. Disclosure of Interest Statement: Funding for the 2003 study was provided by the Prostitution Licensing Authority. Acknowledgement and sincere thanks to the men and women who participated in this study.

Warm was series of collaborative fashion designs workshops delivered as part of the International Kids Carnival hosted by the Venice Biennale Feb 11th - Feb 21st 2012. The workshops were based in the broad research domain of Design for Sustainability and involved an up-cycling process whereby school -aged children how to transform t-shirts into scarves and hats. Workshop participants learnt about the social and ethical imperative to re-cycle, the ways in which garments can be transformed and consequently re-valued, and how form, colour and proportion play a role in the design process. The workshops involved the development of highly visual models, images and translations.
Cooperative choice and its framing effect under threshold uncertainty in a provision point mechanism

This paper explores how threshold uncertainty affects cooperative behaviors in the provision of public goods and the prevention of public bads. The following facts motivate our study. First, environmental (resource) problems are either framed as public bads prevention or public goods provision. Second, the occurrence of these problems is characterized by thresholds that are interchangeably represented as "nonconvexity," "bifurcation," "bi-stability," or "catastrophes." Third, the threshold location is mostly unknown. We employ a provision point mechanism with threshold uncertainty and analyze the responses of cooperative behaviors to uncertainty and to the framing for each type of social preferences categorized by a value orientation test. We find that aggregate framing effects are negligible, although the response to the frame is the opposite depending on the type of social preferences. "Cooperative" subjects become more cooperative in negative frames than in positive frames, whereas "individualistic" subjects are less cooperative in negative frames than in positive ones. This finding implies that the insignificance of aggregate framing effects arises from behavioral asymmetry. We also find that the percentage of cooperative choices non-monotonically varies with the degree of threshold uncertainty, irrespective of framing and value orientation. Specifically, the degree of cooperation is highest at intermediate levels of threshold uncertainty and decreases as the uncertainty becomes sufficiently large.

The subject of the thesis is the mediated construction of author images in popular music. In the study, the construction of images is treated as a process in which artists, the media and the members of the audience participate. The notions of presented, mediated and compiled author images are used in explaining the mediation process and the various authorial roles of the agents involved. In order to explore the issue more closely, I analyse the author images of a group of popular music artists representing the genres of rock, pop and electronic dance music. The analysed material consists mostly of written media texts through which the artists authorial roles and creative responsibilities are discussed. Theoretically speaking, the starting points for the examination lie in cultural studies and discourse analysis. Even though author images may be conceived as intertextual constructions, the artist is usually presented as a recognizable figure whose purpose is to give the music its public face. This study does not, then, deal with musical authors as such, but rather with their public images and mediated constructions. Because of the author-based functioning of popular music culture and the idea of the artist s individual creative power, the collective and social processes involved in the making of popular music are often superseded by the belief in a single, originating authorship. In addition to the collective practices of music making, the roles of the media and the marketing machinery complicate attempts to clarify the sharing of authorial contributions. As the case studies demonstrate, the differences between the examined author images are connected with a number of themes ranging from issues of auteurism and stardom to the use of masked imagery and the blending of authorial voices. Also the emergence of new music technologies has affected not only the ways in which music is made, but also how the artist s authorial status and artistic identity is understood. In the study at hand, the author images of auteurs, stars, DJs and sampling artists are discussed alongside such varied topics as collective authorship, evaluative hierarchies, visual promotion and generic conventions. Taken altogether, the examined case studies shed light on the functioning of popular music culture and the ways in which musical authorship is (re)defined.

Starting point for the study was the notion made in previous studies that the Finnish educational practices are not sufficient in multicultural teaching. The main objective of the research was to find out good multicultural teaching practices developed by experienced teachers. The subject of the research was teachers narratives about the problems, solutions and the development of multicultural academic teaching. Previous research has shown that disturbances in multicultural activity can be caused among other things by cultural and linguistic differences, racism and prejudice and stress related to immigration. The management of multicultural teaching can be examined from the individual point of view as intercultural competence and from the collective point of view as management of the disturbances of multicultural teaching. The development of the management has been illustrated with the models of adaptation and transformative/expansive learning. The methodological approach of the research was narrative. I interviewed six teachers with narrative methods. Half of the interviews were pair interviews. As an analytical framework I used the basic story model by Labov (1972). I analysed critical incidents, resolutions and evaluations of the stories. According to the results the problems of the multicultural academic teaching are diverse. Most often mentioned problems were cultural differences and racism. Problems were managed by developing practices that support the multicultural activity broadly and by reacting to sudden problems intuitively or reflectively. In the management of the academic multicultural teaching the experienced teachers emphasised flexibility, group building and trust, intensified guidance, acting against racism and prejudice and characteristics of the teacher, like patience and sense of humour. The management of multicultural teaching has developed through the accumulation of intercultural experiences, reflection of experiences, cooperative problem solving, following the research of the field and experimenting different approaches. In accordance with the previous studies, this research showed that continuous learning is needed in the management of multicultural teaching. The results can be used in developing academic multicultural teaching and education.

This research examines three aspects of becoming a teacher, teacher identity formation in mathematics teacher education: the cognitive and affective aspect, the image of an ideal teacher directing the developmental process, and as an on-going process. The formation of emerging teacher identity was approached in a social psychological framework, in which individual development takes place in social interaction with the context through various experiences. Formation of teacher identity is seen as a dynamic, on-going developmental process, in which an individual intentionally aspires after the ideal image of being a teacher by developing his/her own competence as a teacher. The starting-point was that it is possible to examine formation of teacher identity through conceptualisation of observations that the individual and others have about teacher identity in different situations. The research uses the qualitative case study approach to formation of emerging teacher identity, the individual developmental process and the socially constructed image of an ideal mathematics teacher. Two student cases, John and Mary, and the collective case of teacher educators representing socially shared views of becoming and being a mathematics teacher are presented. The development of each student was examined based on three semi-structured interviews supplemented with written products. The data-gathering took place during the 2005 2006 academic year. The collective case about the ideal image provided during the programme was composed of separate case displays of each teacher educator, which were mainly based on semi-structured interviews in spring term 2006. The intentions and aims set for students were of special interest in the interviews with teacher educators. The interview data was analysed following the modified idea of analytic induction. The formation of teacher identity is elaborated through three themes emerging from theoretical considerations and the cases. First, the profile of one s present state as a teacher may be scrutinised through separate affective and cognitive aspects associated with the teaching profession. The differences between individuals arise through dif-ferent emphasis on these aspects. Similarly, the socially constructed image of an ideal teacher may be profiled through a combination of aspects associated with the teaching profession. Second, the ideal image directing the individual developmental process is the level at which individual and social processes meet. Third, formation of teacher identity is about becoming a teacher both in the eyes of the individual self as well as of others in the context. It is a challenge in academic mathematics teacher education to support the various cognitive and affective aspects associated with being a teacher in a way that being a professional and further development could have a coherent starting-point that an individual can internalise.

Social media are now widely used for political protests, campaigns, and communication in developed and developing nations, but available research has not yet paid sufficient attention to experiences beyond the US and UK. This collection tackles this imbalance head-on, compiling cutting-edge research across six continents to provide a comprehensive, global, up-to-date review of recent political uses of social media. Drawing together empirical analyses of the use of social media by political movements and in national and regional elections and referenda, The Routledge Companion to Social Media and Politics presents studies ranging from Anonymous and the Arab Spring to the Greek Aganaktismenoi, and from South Korean presidential elections to the Scottish independence referendum. The book is framed by a selection of keystone theoretical contributions, evaluating and updating existing frameworks for the social media age. "Comprehensive and definitive, this is an outstanding book that provides a panoramic view of politics in an era of social media. From the Mediterranean to East Asia to Oceania, from Scandinavia to sub-Sahara Africa to Latin America, the volume as a whole is truly global, yet with nuanced regional and national analyses in each chapter. Theoretically informed, the research presented here breaks new empirical grounds using latest digital methods. The result is a milestone for our collective understanding of new media technology and comparative politics in the twenty-first century." ―Jack Linchuan Qiu, The Chinese University of Hong Kong "This book brings together top scholars from across disciplines and across the globe to examine social media use in a variety of political systems and for distinct purposes. It is required reading for anyone interested in understanding the many ways that digital communication technologies now are used in political life." ―Jennifer Stromer-Galley, Syracuse University

Macadamia growers are under increasing pressure to remain viable in an increasingly competitive global market. A key need is quick access to high quality information. Current industry information is poorly integrated, poorly updated, and because it is largely in hard-copy, is difficult to access efficiently. With the dramatic growth in the use of the internet by growers, as evidenced in a recent industry communications survey, an opportunity exists to address this problem through the development of a high quality, internet-based information “bank”. The bank would bring together the macadamia information resources and collective knowledge of R&D and other relevant agencies into a one-stop information shop, aligned more effectively with grower needs.

The accumulation of deficits with increasing age results in a decline in the functional capacity of multiple organs and systems. These changes can have a significant influence on the pharmacokinetics and pharmacodynamics of prescribed drugs. Although alterations in body composition and worsening renal clearance are important considerations, for most drugs the liver has the greatest effect on metabolism. Age-related change in hepatic function thereby causes much of the variability in older people’s responses to medication. In this review, we propose that a decline in the ability of the liver to inactivate toxins may contribute to a proinflammatory state in which frailty can develop. Since inflammation also downregulates drug metabolism, medication prescribed to frail older people in accordance with disease-specific guidelines may undergo reduced systemic clearance, leading to adverse drug reactions, further functional decline and increasing polypharmacy, exacerbating rather than ameliorating frailty status. We also describe how increasing chronological age and frailty status impact liver size, blood flow and protein binding and enzymes of drug metabolism. This is used to contextualise our discussion of appropriate prescribing practices. For example, while the general axiom of ‘start low, go slow’ should underpin the initiation of medication (titrating to a defined therapeutic goal), it is important to consider whether drug clearance is flow or capacity-limited. By summarising the effect of age-related changes in hepatic function on medications commonly used in older people, we aim to provide a guide that will have high clinical utility for practising geriatricians.

Designed by the Media The Media publicity of Design in the Finnish Economic Press The meaning of design has increased in consumer societies. Design is the subject of debate and the number of media discussions has also increased steadily. Especially the role of industrial design has been emphasised. In this study I examine the media publicity of design in the Finnish economic press from the late 1980s to the beginning of the 2000s. The research question is connected to media representations: How is design represented in the Finnish economic press? In other words, what are the central topics of design in the economic press, and to what issues are the media debates connected? The usually repeated phrase that design discussions take place only on the cultural pages of the daily press or in cultural contexts is being changed. Design is also linked to the consumer culture and consumers everyday practices. The research material has been collected from the Finnish economic press. The qualitative sample consists of articles from Kauppalehti, Taloussanomat and from several economic papers published by the Talentum Corporation. The approach of the research is explorative, descriptive and hermeneutic. This means that the economic press articles are used to explore how design is represented in the media. In addition, the characteristics of design represented in the media are described in detail. The research is based on the interpretive tradition of studying textual materials. Background assumptions are thus grounded in hermeneutics. Erving Goffman s frame analysis is applied in analysing the economic press materials. The frames interpreted from the articles depict the media publicity of design in the Finnish economic press. The research opens up a multidimensional picture of design in the economic press. The analysis resulted in five frames that describe design from various points of view. In the personal frame designers are described in private settings and through their personal experiences. The second frame relates to design work. In the frame of mastery of the profession, the designers work is interpreted widely. Design is considered from the aspects of controlling personal know-how, co-operation and the overall process of design. The third frame is connected to the actual substance of the economic press. In the frame of economy and market, design is linked to international competitiveness, companies competitive advantage and benefit creation for the consumers. The fourth frame is connected to the actors promoting design on a societal level. In the communal frame, the economic press describes design policy, design research and education and other actors that actively develop design in the societal networks. The last frame is linked to the traditions of design and above all to the examination of the cultural transition. In the frame of culture the traditions of design are emphasised. Design is also connected to the industrial culture and furthermore to the themes of the consumer culture. It can be argued that the frames construct media publicity of design from various points of view. The frames describe situations, action and the actors of design. The interpreted media frames make it possible to understand the relation of interpreted design actions and the culture. Thus, media has a crucial role in representing and recreating meanings related to design. The publicity of design is characterised by the five focal themes: personification, professionalisation, commercialisation, communalisation and transition of cultural focus from the traditions of design to the industrial culture and the consumer culture. Based on my interpretation these themes are guided by the mediatisation of design. The design phenomenon is defined more often on the basis of the media representations in the public discourses. The design culture outlined in this research connects socially constructed and structurally organised action. Socially constructed action in design is connected to the experiences, social recreation and collective development of design. Structurally, design is described as professional know-how, as a process and as an economic profit generating action in the society. The events described by the media affect the way in which people experience the world, the meanings they connect to the events around themselves and their life in the world. By affecting experiences, the media indirectly affects human actions. People have become habituated to read media representations on a daily basis, but they are not used to reading and interpreting the various meanings that are incorporated in the media texts.

This paper outlines the development of a reflective process through which student feelings are brought to the surface to advance their learning outcomes. A key notion in relation to the capacity of student development is the ability of students to alter their collective habits of thought and in turn the nature of the learning environment. The paper examines student reflection in the context of students' heightened awareness of self and their potential influence on their environment. The notion of 'surfacing feelings' is used to describe the outcome of individual and group reflection through which several parties become aware of the active reflections of individual students, thereby increasing the potential depth of overall reflection. Finally, the author considers the transferability of the ideas discussed to other educational contexts.

Recommender systems assist users in finding what they want. The challenging issue is how to efficiently acquire user preferences or user information needs for building personalized recommender systems. This research explores the acquisition of user preferences using data taxonomy information to enhance personalized recommendations for alleviating cold-start problem. A concept hierarchy model is proposed, which provides a two-dimensional hierarchy for acquiring user preferences. The language model is also extended for the proposed hierarchy in order to generate an effective recommender algorithm. Both Amazon.com book and music datasets are used to evaluate the proposed approach, and the experimental results show that the proposed approach is promising.

15 Artists 2014 was a group exhibition of 2D and 3D works held at the Redcliffe City Art Gallery between October 23 - December 6, 2014. My contribution to the group show was a collective series of 10 soft sculptures entitled Organs Without Bodies. These works were composed of latex, plaster, wool, thread, wax and rosin. I seek through my art practice to transform bodily affect into concrete knowledge. My primary motivation can be described as a relational and ethical attempt to find balance between the erotic and the aggressive. These objects are outcomes from an ongoing creative meditation of the simultaneity of dichotomies: inside and outside, cognition and emotion, past and present, connection and differentiation, the erotic and the aggressive. Each of these can be perceived separately with a penetrating focus of attention, yet all are contained within the 'space' of an expansive bodily-felt sense of awareness.

The aim of our research is to iteratively refine and begin validating a proposed videogame reward typology and its associated definitions. A mixed methods approach has been taken so as to best evaluate and refine the taxonomy. The views of an expert focus group have been explored and considered. Separately, a review of the videogame rewards observed within recreational videogames has been undertaken and analyzed. The collective findings of both the focus group and the videogame reward review have prompted the redesign of an existing videogame reward taxonomy, resulting in more robust definitions with increased applicability.
