JXTA anonymity through a replicated message-based approach

JXTA is a mature set of open protocols, with morethan 10 years of history, that enable the creation and deployment of peer-to-peer (P2P) networks, allowing the execution of services in a distributed manner. Throughout its lifecycle, ithas slowly evolved in order to appeal a broad set of different applications. Part of this evolution includes providing basic security capabilities in its protocols in order to achieve some degree of message privacy and authentication. However, undersome contexts, more advanced security requirements should be met, such as anonymity. There are several methods to attain anonymity in generic P2P networks. In this paper, we proposehow to adapt a replicated message-based approach to JXTA, by taking advantage of its idiosyncracies and capabilities.

We want Moshiach now! : understanding the Messianic message in the Jewish Chabad-Lubavitch movement

Då man rör sig i New York eller Jerusalem är det inte ovanligt att man stöter på judiska "missionärer" - ett fenomen som annars är ovanligt inom judendomen - och får ett traktat i sin hand som säger "Moshiach är här" eller "Welcome Moshiach". Det är den ultra-ortodoxa rörelsen Chabad-Lubavitch som har blivit känd för sitt utåtriktade missionsarbete och för att ha proklamerat sin ledare, Rabbi Schneerson som messias. Trots att han har varit död sedan 1994 och man från judiskt håll säger att en messias inte kan dö, lever förväntningarna på Rabbi Schneerson kvar inom rörelsen. Den akademiska forskningen har gjort gällande att denna messiastro, som tar sig ett så aktivt uttryck, är en produkt av den existentiella hopplöshet som lägrade sig över det judiska samfundet i och med Förintelsen, därför att väntan på messias omedelbara ankomst ingav livshopp. Dessutom har forskningen från ett religionssociologiskt perspektiv frågat hur en religiös rörelse överlever en så stor besvikelse som att ens ledare inte uppfyller de profetior som talats ut. Avhandlingen "We Want Moshiach NOW!" ifrågasätter den tidigare forskningen genom att påvisa de starka messianska förväntningar som fanns redan på 1700-talet vid rörelsens tillkomst. Avhandlingen tar upp vilka förväntningar som framkommer i det litterära verket "Tanja", författad av rörelsens grundare, och jämför dem med den moderna litteraturen. I "Tanja" ges även förklaringsmodeller till varför en person som man trodde var messias inte är det. Avhandlingens tes är att forskningen inte har beaktat utsagorna i "Tanja" tillräckligt mycket då man försökt förstå den samtida messiastron och de uttryck den tar.

Effective Message Design and Media Mix of Senior Mobile Phone in China

The present research focuses on the study of how to design message and select media in advertising to generate customer’s purchase intention towards senior mobile phone in China. The message design concentrates mainly on message framing and fear appeals study while the media selection method is only based on direct matching. For exploring the main research question, the study utilized qualitative methodology. The data collection consisted of a pre-interview questionnaire, interviews, and three sets of experiments. The experiments were designed to test the selected 18 participants’ responses toward different emotional appeals and message framings. The findings illustrate participants’ understanding of senior mobile phone and their media usage habits. Moreover, positive message framing and emotional appeals in advertising are more effective. Gender differences in responding to emotional appeals were explored as well.

The nature of communication structures of university students in an international web-based computer-supported collaborative learning (CSCL) course

Communication, the flow of ideas and information between individuals in a social context, is the heart of educational experience. Constructivism and constructivist theories form the foundation for the collaborative learning processes of creating and sharing meaning in online educational contexts. The Learning and Collaboration in Technology-enhanced Contexts (LeCoTec) course comprised of 66 participants drawn from four European universities (Oulu, Turku, Ghent and Ramon Llull). These participants were split into 15 groups with the express aim of learning about computer-supported collaborative learning (CSCL). The Community of Inquiry model (social, cognitive and teaching presences) provided the content and tools for learning and researching the collaborative interactions in this environment. The sampled comments from the collaborative phase were collected and analyzed at chain-level and group-level, with the aim of identifying the various message types that sustained high learning outcomes. Furthermore, the Social Network Analysis helped to view the density of whole group interactions, as well as the popular and active members within the highly collaborating groups. It was observed that long chains occur in groups having high quality outcomes. These chains were also characterized by Social, Interactivity, Administrative and Content comment-types. In addition, high outcomes were realized from the high interactive cases and high-density groups. In low interactive groups, commenting patterned around the one or two central group members. In conclusion, future online environments should support high-order learning and develop greater metacognition and self-regulation. Moreover, such an environment, with a wide variety of problem solving tools, would enhance interactivity.

Through the analysis of the messages in advertisements placed in a certain luxury and fine living magazine, message creation strategies are being anticipated.

Measuring Effectiveness of Marketing Message: The Role of Verbal, Visual and Brand Elements

The aim of this paper is to study the role of verbal, visual and brand elements while meas-uring effectiveness of marketing message. The thesis is written in the context of mobile gaming industry. The object of the study is marketing message. To achieve the aim, the main research question was formulated: How do the elements of marketing message, such as verbal, visual and brand, affect the consumer’s attitude toward the ad, emotional response and attention capture? The theory development chapter lays on three corner stones – analysis of previous litera-ture on marketing message and its elements, namely verbal, visual and brand; overview of literature on attitude formation and particularly attitude toward the ad. In addition, investiga-tion of key points of emotional response and attention capture literature finalizes the chap-ter. The empirical part consists of experiment, conducted with 27 participants. Experiment includes the self-report semantically anchored scale, measuring the attitude toward the ad, as well as autonomic measures – eye tracking (attention capture) and facial expressions (emotional response). The results of the experiment showed that the size of the brand element – the logo – has an effect on the attention capture and the overall attitude toward the ad. The bigger the logo, the more time people spend viewing it, and they realise the message is more educa-tional and factual. The measure related to the visual element – the visual complexity – in-creases the intensity of participant’s facial expression. While the measure of verbal ele-ment – the contrast between text and background colours – leads to a better attitude to-ward the ad. The higher the contrast between text and background, the more known the message appears to the viewer.

The effectiveness of a health versus appearance message on pregnant women's intentions to exercise postpartum : the moderating role of self-monitoring

Despite the confimied health benefits of exercise during the postpartum period, many new mothers are not sufficiently active. The present research aimed to examine the effectiveness of 2 types of messages on intention to exercise after giving birth on 2 groups of pregnant women (low and high self-monitors) using the Theory of Planned Behavior as a theoretical basis. Participants were 2 1 8 pregnant women 1 8 years of age and older (Mean age = 27.9 years, SD = 5.47), and in their second or third trimester. Women completed a demographics questionnaire, a self-monitoring (SM) scale and the Godin Leisure Time Exercise Questionnaire for current and pre-pregnancy exercise levels. They then read one of two brochures, describing either the health or appearance benefits of exercise for postpartum women. Women's attitudes, social norms, perceived behavioral control, and intentions to exercise postpartum were then assessed to determine whether one type of message (health or appearance) was more effective for each group. A MANOVA found no significant effect (p>0.05) for message type, SM, or their interaction. Possible reasons include the fact that the two messages may have been too similar, reading any message about exercise may result in intentions to exercise, or lack of attention given to the brochure. Given the lack of research in this area, more studies are necessary to confirm the present results. Two additional exploratory analyses were conducted. Pearson correlations found higher levels of pre-pregnancy exercise and current exercise to be associated with more positive attitudes, more positive subjective norms, higher perceived behavioral control, and higher intention to exercise postpartum. A hierarchical regression was conducted to determine the predictive utility of attitudes, subjective norms, and perceived behavioral control on intention for each self-monitoring group. Results of the analysis demonstrated the three independent variables significantly predicted intention (p < .001) in both groups, accounting for 58-62% of the variance in intention. For low self-monitors, attitude was the strongest predictor of intention, followed by perceived behavioral control and subjective norm. For high self-monitors, perceived behavioral control was the strongest predictors, followed by attitudes and subjective norm. The present study has practical and real world implications by contributing to our understanding of what types of messages, in a brochure format, are most effective in changing pregnant women's attitudes, subjective norm, perceived behavioral control and intention to exercise postpartum and provides ftirther support for the use of the Theory of Planned Behavior with this population.
