Social media has become ubiquitous in modern society. Both as a way to connect with others and as a popular form of entertainment and relaxation. This dependency on social media can lead both to beneficial and adverse consequences. A common concern about social media use relates to how active or passive a user is, with some indicating that passive behaviours, such as absently scrolling through the feed are particularly harmful. Research that investigates social media’s adverse effect on the individual depending on the user’s engagement level currently suffers from problems with categorisation, methodology and philosophy. This thesis sought to fill this research gap. Its research questions were accordingly: “What motivates adult users to use social media at various levels of engagement?” and “What factors of social media use impact adult users’ adverse emotional outcomes?” To answer this research question, the study utilised a methodology of focus group discussion with pre-existing social groups consisting of adults aged 20-30, a demographic with potentially unique insight into their relationship with social media. This was followed by thematic analysis which in turn was placed within a framework of Use & gratification theory and the networked public. These theories were chosen since the research adheres to concepts of the active audience and disagrees with conceptualisations of the social media user as passive. Instead, low to high levels of engagement is used to describe individual behaviours. 4 main themes (Level of engagement, Problematic use, category of use and regulation) were discovered as well as 13 sub-themes. The study discovered that individuals would use social media at several levels of engagement simultaneously but that behaviours could be assembled into four archetypes: Consumption (low level of engagement which included behaviours such as mindless scrolling), Lurking (low level of engagement which included both private and public browsing)

La imagen percibida de la ciudad en el imaginario colectivo se ha visto influenciada, a lo largo del último siglo, por las imágenes que sobre nosotros han proyectado los medios audiovisuales de masas. Estos han ayudado a moldear sus significados y la manera de relacionarnos con sus espacios, catalizando una nueva manera de mirar a partir de la multiplicidad simultánea de —cada vez más— puntos de vista. En los algo menos de 100 años que separan las yuxtaposiciones de Kuleshov en la sala de montaje con el nacimiento de Instagram, la construcción mental de la ciudad y nuestra manera de convivir con ella no ha dejado de transformarse. A través de tres momentos escogidos: el montaje cinematográfico y el espacio de la yuxtaposición, la televisión por cable y la ciudad zapping; y las redes sociales y el scroll infinito, se estudian los impactos del medio en nuestra concepción del espacio urbano., The perceived image of the city in the collective imagination has been influenced, over the last century, by the images projected onto us through mass audiovisual media. These media have played a crucial role in shaping the city’s meanings and our interaction with its spaces, fostering a new perspective that encompasses a multiplicity of viewpoints. In the span of less than 100 years, from Kuleshov’s pioneering juxtapositions in the editing room to the advent of Instagram, the mental construction of the city and our relationship with it have continuously evolved. This research explores the impacts of different mediums on our perception of urban space through three pivotal moments: film montage and the space of juxtaposition, cable television and the zapping city, and social networks and infinite scrolling, we examine the impact of media on our understanding of urban context.

As the number of social media platforms on the market is continuously increasing, concerns and questions about their effects on mental health are also rising. The current study explored the relationship between the problematic use of social media, the absent-minded scrolling behavior, and levels of anxiety. One hundred and fifty-four participants were given an online questionnaire to assess their manners of social media use focusing on the social media scrolling experience and self-reported anxiety levels using the Generalized Anxiety Disorder Assessment tool (GAD-7). There were strong and positive relationships between the problematic use of social media platforms and the absent-minded scrolling behavior, with a statistically significant relationship with levels of anxiety. Results indicated that social media scrolling is becoming a problematic habit that helps users escape their reality and avoid problems.

Business process modeling is an important activity for developing software systems—especially within digitization projects and when realizing digital business models. Specifying requirements and building executable workflows is often done by using BPMN 2.0 process models. Although there are several style guides available for BPMN, e.g., by Silver and Richard (BPMN method and style, vol 2, Cody-Cassidy Press, Aptos, 2009), there has not been much empirical research done into the consequences of the diagram layout. In particular, layouts that require scrolling have not been investigated yet. The aim of this research is to establish layout guidelines for business process modeling that help business process modelers to create more understandable business process diagrams. For establishing benefits and penalties of different layouts, a controlled eye tracking experiment was conducted, in which data of 21 professional software developers was used. Our results show that horizontal layouts are less demanding and that as many diagram elements as possible should be put on the initially visible screen area because such diagram elements are viewed more often and longer. Additionally, diagram elements related to the reader’s task are read more often than those not relevant to the task. BPMN modelers should favor a horizontal layout and use a more complex snake or multi-line layout whenever the diagrams are too large to fit on one page in order to support BPMN model comprehension.

With the introduction of new technologies for the web like HTML5 and CSS3, new possibilities have emerged. An example of such is parallax scrolling which is based on the ‘parallax effect’. The parallax effect is the illusion of depth which is created by moving multiple layers in different speeds. This effect is commonly used in e.g. 2D games where you have a slow moving backgrounds relative to the character you play. While such an effect can certainly be appealing on a website, opinions differ. This paper examines the overall acceptance of parallax scrolling and how it is perceived in hedonic contexts such as infographics and storytelling. The research was conducted using both qualitative and quantitative methods. Findings of the study indicate that parallax scrolling is generally well liked. It has shown its strengths in the aesthetic as a result of the illusion of depth. Another strong point of parallax scrolling is its entertaining value which makes content more fun and interesting by involving moving elements. However, in the study a website with parallax scrolling was not perceived as much better than a traditional website. While statistical significance in the perception was found, it can be argued that those differences were caused by a contrast effect. Further research is suggested by using a larger sample size., Introduktionen av nya teknologier såsom HTML5 och CSS3, har skapat nya möjligheter för webbutvecklare. Ett sådant exempel är parallax scrolling som baseras på ‘parallax-effekten’. Parallax-effekten är illusionen av djup som uppstår när flera lager av grafik rör sig i olika hastigheter. Effekten har använts ofta i 2D spel där man har bakgrunder som rör sig långsamt relativt spelkaraktären. En sådan effekt kan säkerligen vara mycket tilltalande, däremot finns det delade åsikter. Denna uppsats undersöker den generella inställningen till parallax scrolling och hur den uppfattas i hedoniska kontexter såsom “infographics” och “storytelling”. Studien har genomförts genom att använda både kvalitativa och kvantitativa metoder. Resultaten tyder på att parallax scrolling är väl omtyckt. Den har visat sin styrka i det estetiska, vilket är tack vare illusionen av djup. Parallax scrolling har även ett underhållningsvärde som gör innehållet mer intressant och roligt. Däremot har studien även visat att en webbsida med parallax scrolling inte är särskilt bättre än en traditionell webbsida avseende användarupplevelse. Även om en statistisk signifikans har trätt fram kan man argumentera att detta resultat kan tillskrivas kontrasteffekten. Vidare studier är rekommenderade med en större provstorlek.

Application various different visualization schemes are conceivable. This paper presents a multi-layer based visualization method, enabling fast data browsing of mobile mapping data. In contrast to systems like Google Street View the proposed visualization does not base on 360° panoramas, but on colored point clouds projected on partially translucent images. Those images are rendered as overlapping textures, preserving the depth of the recorded data and still enabling fast rendering on any kind of platform. Furthermore the proposed visualization allows the user to inspect the mobile mapping data in a panoramic fashion with an immersive depth illusion using the parallax scrolling technic.

The paper is devoted to further development of previously advanced approach in nanostructuring. This approach is based on using few monolayer-thick bifilms for scrolling 3D heterostructures from them. In this work, initially flat strained GaAs/InGaAs bilayers with Langmuir-Blodgett films deposited onto them were rolled up in tube-shaped scrolls. It is shown that, giving local parts of the surface of the resulting tubes hydrophilic or hydro-phobic properties. one can fabricate a perfectly ordered array of free-standing nanotubes., Pres: 8th Int Symp Nanostructures: Physics and Technology, St Petersburg, Russia. 19-23 Jun 2000, p92-94.

A software object for providing a display of a scrolling real-time graph includes a window, a fixed axis within the window, a scrolling axis within the window, axis labels within the window, a plot within the window, and facility for viewing obscured regions of the graph along the scrolling axis.

An experiment was conducted to evaluate menuing and scrolling as alternative information management techniques. A menu structure (4-3) and three scrolling methods, line-by-line, half-screen, were tested. Level of goal word familiarity and size of display window were also examined. The task consisted of locating a target goal word with one of the four access methods. A touch tablet was used to interact with the computer system. Members of a single set of 64 words, 32 unfamiliar, served as goal words in all conditions. Performance data were collected from 48 subjects. Each subject received both word familiarity levels. Access method and window size were between-subjects variables. Results of an analysis of variance on mean total task time revealed significant access method, word familiarity, and access method by word familiarity interaction effects. Line-by-line scrolling was fastest, followed by full-screen scrolling, half-screen scrolling, and menuing. Separate analyses of variances were conducted on total task time for familiar and unfamiliar word sets. The fastest condition depended on the familiarity level of the goal word, but not on window size. When the goal words was familiar, menuing was fastest, followed by line- by-line, full screen, and half-screen scrolling. For unfamiliar goal words, line-by-line scrolling was fastest, followed by full-screen scrolling, half-screen scrolling, and menuing.
