The type of media shared through social media channels has shifted from text content to include an increasingly large number of images. Visual traces resulting from people's online social behavior have the potential to reveal insights about our habits, activities and preferences. The role of social network-related factors have been well studied in previous research. Yet, few studies have sought to understand how user behavior in social networks is dependent on the image itself. The goal of my dissertation is to understand how people engage with image content, and I seek to uncover the role of presentation and image content on people's preferences. To achieve this goal, I study the image sharing communities, Flickr, Instagram and Pinterest, using quantitative and qualitative methods. First, I show how colors -- a fundamental property of an image -- could impact the virality of an image on Pinterest. I consider three dimensions of color: hue, saturation and brightness and evaluate their role in the diffusion of the image on Pinterest, while controlling for social network reach and activity. Next, I shift the focus from abstract colors to a higher-level presentation of images. I study the role of filters on the Flickr mobile application as proxies to visual computation. To understand how people use filters, I conduct an interview study with 15 Flickr mobile users about their filter use. I analyze Flickr mobile images to discover the role of filters in engaging users. Presentation is not the only factor that makes an image interesting. To gain deeper insights in what makes an image more engaging in social image sharing sites, I study the images of people on the Instagram network. I compare images of people with those that do not have faces and find that images with human faces are more engaging. I also look at the role of age and gender of people in the image in engaging users. Finally, I examine different content categories, with and without filters, and study the impact of content category on engagement. I use large-scale data from Flickr and interviews with Flickr mobile users to draw insights into filter use and content engagement. This dissertation takes a first step toward understanding content and presentation of images and how they impact one aspect of user behavior online. It provides several theoretical and design implications for effective design, creation and imposition of rules on image sharing communities. This dissertation opens up a new direction for future research in multimedia-mediated communication.

Recent trends in social networking site (SNS) use amongst teachers have led to some alarming circumstances. Practicing and pre-service teachers have been fired or otherwise punished (e.g. suspension, licensure revocation, etc.) for a variety of offenses related to their SNS use, ranging from sinister to morally ambiguous offenses, and have been encouraged or required by school administrators, professors, and others in positions of power to use SNS in particular ways. Past research on the topic of SNS in education and SNS professionalism has focused on issues of implementation (e.g. how to use SNS to support learning) or utility (e.g. how to use SNS to successfully achieve career goals). Missing from this discussion, however, is an understanding of how teachers (and those preparing to become teachers) naturally come to participate in SNS, why they participate in the ways that they do, and how this use is related to their identity. This study seeks to fill a gap in the literature by understanding pre-service teachers’ uses of SNS in terms of previous experiences, cultural expectations, social benefits, connections to identity construction and maintenance, and how these uses and beliefs regarding SNS begin to change in response to professionalization processes. Grounded theory is employed to generate an explanatory construct, which I refer to as the Acceptable Identity Fragment (AIF). The AIF is then used to understand and illustrate issues surrounding SNS use in education. Major findings suggest that 1) pre-service teachers’ identities in SNS represent a fragment of their authentic identities, 2) pre-service teachers use various SNS differently in conjunction with each SNS’s embedded values and assumptions about identity, 3) SNS use raises various problematic issues surrounding identity and how pre-service teachers are perceived and judged as individuals (e.g. digital persistence, lateral surveillance, etc.), and 4) professionalization processes alter and restrict pre-service teachers’ ability and comfort to express themselves in SNS. These findings lead to discussion, implications, and recommendations on a variety of topics including the following: institutional uses of SNS in education, relationships between fragmented and authentic identities, SNS literacy development, and cultural issues of SNS use. / text

The study examines the differences between women’s and men’s perception of visual aesthetics on Pinterest. Therefore, we have chosen to examine the visual aesthetics through the lens of simplicity, diversity, colour and craftmanship. The purpose of the study is to contribute to a deeper understanding of the perception of visual aspects between men and women on the social media platform Pinterest. As society grows and develops on a variety of levels, we humans must increasingly adapt to a higher pace of life. A higher pace of life can mean that we as humans are forced to have a greater focus on where we spend our time and what we choose to focus our attention on. This indicates that people in today's society and in their everyday lives must decide which social media they choose to pay attention to. We ask ourselves the question: How do people do when they must distribute time and attention over social media? What factors drive these decisions? Are men and women attracted to different factors? After studying the results, we were able to conclude that female participants valued Pinterest as less aesthetically pleasing than the male participants did. Finally, we would like to point out that even though the majority of users are women on Pinterest, our study shows that men value the visual aesthetics higher than women.

Para o desenvolvimento deste problema de pesquisa, inicialmente, realiza-se uma explicação das abordagens e dos procedimentos metodológicos, inspirados em um agir arqueológico, seguida de um apanhado sobre o conceito de interface por meio de algumas concepções em torno do termo, até se chegar ao conceito-chave desta dissertação, interface cultural. Com isto, avança-se sobre a instrumentalização da pesquisa, por meio da escavação de imagens e da identificação de molduras (KILPP, 2010), sucedido de análise de material empírico coletado e agrupado em três constelações nomeadas como HCI, plasticidade e atravessamentos entre produtos culturais on-line. A pesquisa é finalizada com dois principais movimentos, o primeiro respondendo à pergunta inicial de pesquisa, em que se percebe um deslocamento do conceito inicial de interface cultural devido a conjunturas advindas da web 2.0, e o segundo trazendo, por meio de um quadro, uma proposta de estrutura de análise de artefatos culturais on-line. / The study aims, from a communicative and technocultural approach, to understand how the website Pinterest, based on the examination of its main operating logics, updates the concept of cultural interface coined by Manovich (2001). To develop this research problem, initially, it is carried out an explanation of the methodological approaches and procedures, inspired by an archaeological behave, followed by an overview of the interface concept through some conceptions around the term, until reaching the key concept of this dissertation, cultural interface. With this, it advances on the instrumentalization of the research, digging through images and identifying frames (Kilpp, 2010), followed by analysis of empirical material collected and grouped into three constellations named as HCI, plasticity and crossings between online cultural devices. The research concludes with two main movements, the first answering to the initial research question, it is realized a shift from the initial concept of cultural interface due to contexts arising from web 2.0, and the second bringing through a frame, a proposal of an analysis structure of online cultural devices.
