In this paper we examine how young women present themselves on their weblogs. The main purpose of this study is to get their own opinions and thoughts about their own blogging, to see if we can find norms for how they present themselves and how the presentation online matches themselves offline. We put this in relation to information technologies, social software and Computer mediated communication, CMC. It´s also in our interest to see how the phenomenon of blogs, its role and methods of communication have changed and developed in the last few years, and whether there are differences in the way people use it according to age. The major finding is that, unlike previous research, the women in our study tend to be themselves in their weblogs and they do not manipulate their identities. They main use of their weblogs is as a space where they feel free to write what's on their mind, their thoughts and feelings and to inform their relatives about their everyday life, but also as a diary to remember their past and for self examination.

Sandvik IT Services (SITS) ambition is to provide a smooth and suitable IT environment for the whole Sandvik organization. The idea is that SITS should provide end-to-end solutions globally in an efficient manner. To ensure that they can provide this, they have to be efficient in their work. To handle problems regarding incident and support, they have a large TV screen that shows important information about different processes. The demand for the information has increased; therefore the information displayed on the screen has also increased. Today, the amount of information on the screen is too big and it makes the information difficult to read and absorb. This work will help make SITS application management more effective in the future. Through Workshops for both managers and developers, it is necessary to find out the difference of what SITS requires to diversify priority information. And also be able to view the information in a user-friendly way, a layout of the information is suggested. The result of this work is to produce a design proposal.

Gesture-based interaction has long been seen as a natural means of input for electronic presentation systems; however, gesture-based presentation systems have not been evaluated in real-world contexts, and the implications of this interaction modality are not known. This thesis describes the design and evaluation of Maestro, a gesture-based presentation system which was developed to explore these issues. This work is presented in two parts. The first part describes Maestro's design, which was informed by a small observational study of people giving talks; and Maestro's evaluation, which involved a two week field study where Maestro was used for lecturing to a class of approximately 100 students. The observational study revealed that presenters regularly gesture towards the content of their slides. As such, Maestro supports several gestures which operate directly on slide content (e.g., pointing to a bullet causes it to be highlighted). The field study confirmed that audience members value these content-centric gestures. Conversely, the use of gestures for navigating slides is perceived to be less efficient than the use of a remote. Additionally, gestural input was found to result in a number of unexpected side effects which may hamper the presenter's ability to fully engage the audience. The second part of the thesis presents a gesture recognizer based on discrete hidden Markov models (DHMMs). Here, the contributions lie in presenting a feature set and a factorization of the standard DHMM observation distribution, which allows modeling of a wide range of gestures (e.g., both one-handed and bimanual gestures), but which uses few modeling parameters. To establish the overall robustness and accuracy of the recognition system, five new users and one expert were asked to perform ten instances of each gesture. The system accurately recognized 85% of gestures for new users, increasing to 96% for the expert user. In both cases, false positives accounted for fewer than 4% of all detections. These error rates compare favourably to those of similar systems.

<p>In this Ph.D. dissertation, the capacity of cultured bovine polymorphonuclear neutrophils (PMNs) to passively acquire functional membrane proteins from apoptotic or necrotic cells was examined. The rapid transfer of membrane proteins from a variety of syngeneic, allogeneic and xenogeneic donor cells to PMNs was observed. In contrast to PMNs from other species, bovine PMNs did not express endogenous major histocompatability class II (MHC II) protein, either constitutively or inducibly. The entire bovine PMN population was, however, able to acquire detectable levels of surface MHC II or cluster of differentiation (CD) 3 protein following PMN co-culture with cells in conditions which permitted close contact with dieing cells. Therefore, it was hypothesized that membrane lipids and proteins were acquired by bovine PMN following fusion with microparticles (MPs) shed from either apoptotic or necrotic cells. </p> <p>It was then determined whether the lifespan of bovine PMNs could be sufficient to provide an opportunity for PMNs to interact with T cells. Lymphocyte recruitment to sites of inflammation often occurs 3-5 days after the initial PMN recruitment. PMN survival would need to span this interval to provide an opportunity for an interaction between PMNs and lymphocytes. Pro-inflammatory cytokines, such as interferon (IFN)-ã and granulocyte macrophage colony stimulating factor (GM-CSF), and bacterial lipopolysaccharide (LPS) were observed to prolong the lifespan of cultured PMNs beyond 96 hours. These observations supported the conclusion that it was biologically possible for PMNs and T cells to interact at sites of inflammation.</p> <p>Using confocal microscopy, direct evidence was provided for the formation and release of MPs from peripheral blood mononuclear cells (PBMCs) and the attachment of these MPs to bovine PMNs. A time-dependent integration of both MP membranes and integral membrane proteins into the PMN plasma membrane was also observed. The passively acquired membrane lipids and proteins then diffused throughout the PMN plasma membrane. Another observation was the formation of MPs which contained donor cell cytoplasmic proteins and subsequent transfer this cytoplasmic protein to recipient PMNs. These observations raised the possibility that MPs could also transfer genetic material. Thus, confocal microscopy provided direct evidence that MPs were one mechanism by which bovine PMNs could passively acquire membrane lipids and integral membrane proteins.</p> <p>Finally, the functional consequences of passive acquisition of membrane proteins were examined using two different approaches. A significant increase in green fluorescent protein (GFP) transgene expression was observed following PMN infection using the GFP expressing bovine adenovirus vector (BAV304). These PMNs had passively acquired membranes from an adenovirus permissive cell line. This observation provided indirect evidence for the passive acquisition of a functional viral receptor protein. Direct evidence that PMNs passively acquired functional membrane proteins was provided by the observation that the passive transfer of ovine MHC II molecules to bovine PMNs enabled these cells to induce antigen-specific proliferation and cytokine expression by xenoreactive T cell lines. Despite a reduction in amplitude and duration, T cell responses induced by PMNs were qualitatively similar to those observed following activation by the stimulator B cell line. These observations supported the conclusion that PMNs could function as antigen presenting cells (APCs) following the passive acquisition of MHC II protein.</p> <p>In conclusion, this research project provided evidence that bovine PMNs have an impressive ability to acquire membranes and functional integral membrane proteins from dead or dying cells. The implications of this transfer of immunological information are discussed within the context of the role which PMNs might play in both innate and adaptive immune responses. </p>

Since APRANET, the predecessor of global internet, came into being during the 1960s, the advancements of networking technologies over the decades have created online communities such as MUDs, BBS, and newsgroups that allow users in different locations to exchange messages and share information. Nowadays, there are even wiki websites that invite all users to edit any page or to create new pages, and Yahoo! Answers, a community-driven knowledge market website where users can submit their questions and answer questions asked by other users. With such a variety of digital communities, individuals choose their own favorites to interact with others. Especially in recent years, with personal blogs, online photo albums, and micro-blogging taking the lead, more personalized features such as the display picture and user name, deep profiling, avatar and even personal page, are integrated into online discussion forums for individual users to freely present themselves. On the other hand, there are Wikipedia and MIT OpenCourseWare, both web-base collaborative projects that invite the collaboration and contributions of users identifying with their founding goals. Based on these observations, this thesis takes personal and social perceive into account. The research adopted self-presentation and social identity as the factors that can affect community member¡¦s participation, commitment, and knowledge contribution in the online communities. As hypothesized, community member¡¦s participation can motivates their commitment and knowledge contribution to the community. Furthermore, community member's identification with the online communities fosters their participation and commitment while community member¡¦s self-presentation, reflecting the degree of their participation and commitment though, has no direct relation in making any knowledge contribution to online communities.

The aim of this paper is to make a cultural analysis of how young Swedes present themselves and review other’s presentations on the dating application Tinder. I have interviewed seven people between the age of 20 and 34 with experiences from using Tinder and/or other dating applications and websites. Characteristic for my informants is that they have a completed or ongoing higher education, that they call themselves feminists and have leftist political views. These common characteristics have influenced my results, which I have pointed out in my analysis.    I have done a thematic analysis, which means that I have highlighted interesting themes brought up by the informants during the interviews.  These have been further analyzed from the theoretical concepts of self-presentation, gender and social class.      In addition to the interviews, I have conducted a self-reflective analysis of how I present myself and judge other people's profiles on Tinder. Since I am a young university student and consider myself to be a feminist with leftist valuations, it could be expected that I have similar preferences and ways of interpreting other people's Tinder profiles as my informants.      As the results show, my informants have more or less deliberately used different strategies to control what kind of impression their profile visitors get of them. Most of the informants express a strong political awareness and believe that it is important that their dating partner have similar values ​​as themselves. They often make judgments of which values other people have based on what kind of clothing style, poses and gestures they present themselves with on Tinder. But even though my informants seem to have very clear criteria for what kind of persons they want to date, some of them also express a curiosity about meeting people with values, styles and tastes that differs from their own.        One of my informants had different experiences from Tinder than the others, since she was the only one who used the dating application to meet persons of the same sex. How LGBTQ people experience Tinder is a subject that would be interesting to do some further research on.

This study explores how college students present themselves on Facebook, a social networking website, and the impressions they want their fellow students to form of them when looking at their profiles. Goffman's dramaturgical and impression management framework served as a theoretical lens through which Facebook profiles were explored. Employing an ethnographic research design, data for this study were collected during eight-months of participant observation, 30 photo-elicitation interviews, and a photographic content analysis.Facebook has been rapidly adopted by undergraduate students who use it to maintain existing relationships and also as a medium in which to present themselves, especially through photographs. This study provides college administrators and student affairs professional some information about how undergraduates use Facebook and how Facebook can assist them in better understanding their institution's own student culture.Because photographs are instrumental to Facebook use, this study focused on the many images students place on their profiles. The use of photographs in social research is limited and it is hoped that this study will lay the ground work for further use of visual methods. This study found that college students believe that other college students are the primary audience for their profiles. Also, college students use six general "fronts" that lead audience members to see them as: (1) partier, (2) social, (3) adventurous/risk-taker, (4) humorous/funny/silly, (5) part of larger community, and (6) unique. Taken together, these fronts represent an "idealized" undergraduate. Students use props, settings, and gesture to provide their audience members visual cues to help them form the desired impressions. Much of the material that students place on Facebook is meant to be humorous or only understood by a small group of friends. Also, students only show a "narrow strip of activity" in their profiles.
