THE MATCH GAME: INVESTIGATING THE EFFECT OF MESSAGE FRAMING ON PARENTS’ INTENTIONS TO VACCINATE THEIR CHILDREN AGAINST HPVGainforth, Heather Louise 13 July 2010 (has links)
In Canada, parental acceptance and uptake of the HPV vaccine has been low. There is a need for more effective HPV vaccination health messages for parents. Whether a message is framed in terms of the benefits of engaging in the behaviour (gain frame), the costs of failing to engage in the behaviour (loss frame) or both the benefits and the costs (mixed frame) has potential to impact parents’ decision making. The appropriate frame of a message may depend on the recipient’s sex and involvement with the health issue. The purpose of this study was to investigate the persuasiveness of gain-, loss- and mixed-framed messages on mothers’ and fathers’ intentions to have their young son or daughter vaccinated against HPV. The study used a 3 Frame x 2 Sex of Parent x 2 Sex of Child design. We randomly assigned participants (n=367) to read a framed message and then complete a 29-item questionnaire assessing theoretical determinants of parental consent for vaccination. ANCOVAs revealed a three-way interaction for intentions to speak to a doctor about the HPV vaccine, F(2, 342)=3.66, p =.03, perceived severity of HPV, F(2, 347) = 3.10, p = .05, and for anxiety about their child contracting HPV, F(2, 342)=3.58, p=.02. Effect size comparisons revealed that gain-framed messages seem to persuade parents who are the opposite sex to the child for whom they are considering the vaccine. In turn, loss- and mixed-framed messages may persuade parents who are the same sex as the child for whom they are considering the vaccine. Perceived severity of HPV and anxiety about HPV mediated the relationship between message frame and intentions for some parent-child dyads. Findings have implications for constructing effective messages encouraging parents to consider having their child vaccinated against HPV. / Thesis (Master, Kinesiology & Health Studies) -- Queen's University, 2010-07-07 23:06:25.757 Read more

IMPROVING MESSAGE-PASSING PERFORMANCE AND SCALABILITY IN HIGH-PERFORMANCE CLUSTERSRASHTI, Mohammad Javad 26 January 2011 (has links)
High Performance Computing (HPC) is the key to solving many scientific, financial, and engineering problems. Computer clusters are now the dominant architecture for HPC. The scale of clusters, both in terms of processor per node and the number of nodes, is increasing rapidly, reaching petascales these days and soon to exascales. Inter-process communication plays a significant role in the overall performance of HPC applications. With the continuous enhancements in interconnection technologies and node architectures, the Message Passing Interface (MPI) needs to be improved to effectively utilize the modern technologies for higher performance.
After providing a background, I present a deep analysis of the user level and MPI libraries over modern cluster interconnects: InfiniBand, iWARP Ethernet, and Myrinet. Using novel techniques, I assess characteristics such as overlap and communication progress ability, buffer reuse effect on latency, and multiple-connection scalability. The outcome highlights some of the inefficiencies that exist in the communication libraries.
To improve communication progress and overlap in large message transfers, a method is proposed which uses speculative communication to overlap communication with computation in the MPI Rendezvous protocol. The results show up to 100% communication progress and more than 80% overlap ability over iWARP Ethernet. An adaptation mechanism is employed to avoid overhead on applications that do not benefit from the method due to their timing specifications.
To reduce MPI communication latency, I have proposed a technique that exploits the application buffer reuse characteristics for small messages and eliminates the sender-side copy in both two-sided and one-sided MPI small message transfer protocols. The implementation over InfiniBand improves small message latency up to 20%. The implementation adaptively falls back to the current method if the application does not benefit from the proposed technique.
Finally, to improve scalability of MPI applications on ultra-scale clusters, I have proposed an extension to the current iWARP standard. The extension improves performance and memory usage for large-scale clusters. The extension equips Ethernet with an efficient zero-copy, connection-less datagram transport. The software-level evaluation shows more than 40% performance benefits and 30% memory usage reduction for MPI applications on a 64-core cluster. / Thesis (Ph.D, Electrical & Computer Engineering) -- Queen's University, 2010-10-16 12:25:18.388 Read more

Examining the Link between Framed Physical Activity Messages and Behaviour: An Application of the Communication Behaviour Change ModelBERENBAUM, ERIN 08 September 2012 (has links)
Physical inactivity is a national issue affecting more than half of all Canadian adults (Colley et al., 2011). Health messaging, including message framing, has been a popular medium for encouraging individuals to adopt recommended health behaviours such as physical activity. Previous research has demonstrated that gain-framed messages, which emphasize the benefits of a behaviour, are more effective at promoting physical activity (PA) than loss-framed messages which emphasize the costs. However, the mechanism through which this facilitating effect occurs is unclear. The current study examined the effects of message framing on attention, attitudes, recall, decision to be active and behaviour as well as the mediating effects of these variables on the frame-behaviour relationship in accordance with the communication behaviour change (CBC) model (McGuire, 1989). Sixty moderately active women, aged 18-35 viewed 20 gain- or loss- framed ads and 5 control ads while their eye movements were recorded via eye tracking. Attitudes towards PA, message recall, decision to become active and PA behaviour during an acute bout of exercise were measured immediately following ad exposure. Self-reported PA was measured one week later. Univariate ANOVAs, ANCOVAs and logistic regressions were conducted to examine the effects of message framing on each level of the CBC model. The gain-framed ads attracted greater attention, ps<0.05, produced more positive attitudes, p = .06, were better recalled, p < .001, influenced decisions to be active, p = .07, and had an immediate and delayed impact on behaviour, ps < .05, compared to the loss-framed messages. However, mediation analyses failed to reveal any significant effects suggesting that alternate mechanisms may be influencing framing effects on behaviour. This study demonstrates the effects of framed messages on several novel outcomes; however the mechanisms underlying these effects remain unclear. / Thesis (Master, Kinesiology & Health Studies) -- Queen's University, 2012-09-08 16:50:51.877 Read more

創新生意模式 – 案例分析 LINE / New Business Models of Innovation – Case study of LINE李儒婷, Lee, Sabrina Unknown Date (has links)
創新生意模式 – 案例分析 LINE / As more people around the world start using smartphones, instant-messaging apps are emerging not only as an alternative to conventional mobile text-messaging, but also as a social network that could replace some of the roles played by Facebook Twitter and others.
One of the fastest-growing messaging apps in the world is LINE, developed and operated by Tokyo-based LINE Corp. Just over the past year, LINE has seen the number of its users surge nearly fourfold to more than 500 million. In this paper, we will discuss the reason why LINE become so popular, and how is it new business model work. The main reason LINE become so successful is that LINE grasp the essential needs of users and it also look deeply insight the market. Each function LINE had was not innovative at that time, just like games, photo-sharing, and a Facebook-like home page and timeline, however a lot of people would find it convenient if one app can let them experience many different things, then it combine all the function to become a successful LINE. It also created a new way to communicate for boring text message. It create its virtual stickers often featuring cute and quirky cartoon characters that people can send as messages which change users communicate behavior to use stickers instead of text.
By these cute character it also create new business model. The company’s revenue comes from the sales of virtual stickers as well as virtual items sold in games. Also generate with game title, which design with LINE character. The app also makes money by charging businesses that use official Line accounts to distribute promotional messages. In the future, LINE's ambition is to becoming a broader platform for social network and entertainment. The communication app category is crowded and competitive; therefore the company has to create its irreplaceable value to stand stable in this number one position. Read more

The effect of goal orientation, model idealisation, and message framing on the effectiveness of cosmetics advertising.Worsley, Rachael Elizabeth January 2015 (has links)
Women from across the globe purchase and consume cosmetics in order to achieve their appearance goals and it is generally agreed that a consumers’ goal orientation may influence their interpretation of advertising materials and thus the purchase decision-making process. The cosmetics industry promotes their products using almost exclusively images of attractive, young, highly idealised women, and thus has a significant influence on female appearance ideals worldwide. Extensive research connects viewing idealised images to negative outcomes for consumers’ self-concept, however there are mixed results regarding the effectiveness of idealised models in advertising. Moreover, there are mixed results regarding the effectiveness of different message frames. The overall aim of this thesis is to investigate the effects of possible selves and cosmetic advertising on the consumption of cosmetic products. This research draws together areas of literature which have been studied in varying settings in order to determine the individual and collective effects of these independent variables; possible selves, model idealisation and message framing, on women’s attitude toward cosmetic advertisements and purchase intentions in the cosmetic product context.
To understand the effects that goal orientation, as well as the images and text of cosmetic advertisements have on cosmetics consumption, an online experiment was conducted using a 2x3x2 between-subjects factorial design. The study manipulated three independent variables, namely, salient possible self (hoped-for and feared), model idealisation (more idealised model, less idealised model and no model) and regulatory message framing (desired reference and undesired reference) and measured the impact of these variables on attitude toward the ad and resulting purchase intention. The final data set was comprised of 420 responses from 18-35 year old females.
A series of ANCOVA analyses were used to determine the effects of possible selves, model idealisation and message frames on consumers’ attitude toward the ad and their purchase intention. The results indicate hoped-for selves, no model advertisements and desired message frames are independently the most effective in the cosmetics context. However, the goal-compatibility hypothesis was not supported. Furthermore, findings indicate an interaction between the image and the message of cosmetics advertising, which suggests cosmetic advertisers must carefully consider the combination of the images and messages they use to promote their brand and products. The theoretical and managerial implications, as well as direction for future research are discussed. Read more

Consumer Sense of Power and Message Assertiveness in Food AdvertisingWang, Xin 06 September 2017 (has links)
Scant research on food advertising and purchase decisions has examined the moderating role of social constructs such as power. In this research, I investigate how consumers’ sense of power influences the persuasiveness of message assertiveness in food advertising. The agentic–communal framework of sense of power and findings suggests that high-power individuals are more likely to adopt and be receptive to strong, competent information and communication strategies than low-power individuals in interpersonal communication. In this research, I propose a new theoretical framework that predicts how message recipients’ sense of power enables or weakens the persuasiveness of the assertive message such as, “You must buy [the name of the advertised food].”
More specifically, I looked at the likelihood of purchasing ‘vice’ versus ‘virtue' foods after viewing the ad. I argue that for high-power individuals, an assertive tone in the food ads would increase the purchase of a vice food and decrease the purchase intent of a virtue food. However, for low-power individuals, an assertive tone in the food ads would decrease the purchase of a vice food but increase the purchase intent of a virtue food. Low power is less congruent with assertive messages but more congruent with non-assertive messages.
Across three studies, I provide empirical support for the predictions and the congruence mechanism. The results show that high-power consumers process assertive messages more fluently than non-assertive messages. Low-power consumers process assertive messages less fluently than non-assertive messages. Processing fluency increases the relative focus on tastiness in food evaluation, but process dis-fluency increases the relative focus on healthiness in food evaluation. The findings of this research have important implications for developing effective marketing communications and promoting healthy eating. Read more

Toward a Critique of the Message Construct in CommunicationWilson, John K. (John Kenneth) 08 1900 (has links)
The idea of an inherent structure of meaning in human communication is identified as the message construct. Traces of the construct in textbook models of the basic communication process and in popular magazine images of communication are examined. The argument is raised that objectifying the message has resulted in a paradigm which focuses disproportionately on explicit, representational, and instrumental aspects of communication. An alternative conception is proposed which would take into account implicit, constitutive, and generative aspects.

Exploring the impact of message framing on sustainable consumption choicesNaidoo, Dhatchani K. 09 June 2011 (has links)
This study is concerned with understanding the impact of message framing in influencing choice within the sustainable consumption domain. Over-consumption has been proven to be a main cause of environmental degradation, and a shift to sustainable consumption practices is needed. Yet research has found that despite knowledge of environmental issues, and a supportive attitude, pro-environmental behaviour amongst consumers is lacking, with a key influence being the lack of personal utility found in the pro-environmental choice. This study attempts to contribute to narrowing the knowledge attitude practice gap in this domain, by using message framing to isolate the personal utility available in a sustainable choice, thereby influencing a pro-environmental outcome.A study was conducted to determine the main and interaction effects of various salient message frames (reference dependence, loss aversion and time sensitivity) on behavioural intention within sustainable consumption context. Environmental attitude was also tested to ascertain the interaction effect of this variable with the other independent variables and the resultant impact on the choice made. Variables were manipulated in a 2x2x2 factorial design. Results yielded the hypothesised significance of main effects for time sensitivity, but not for reference dependence or loss aversion. In addition no three way interaction for reference dependence by loss aversion by time sensitivity was found. No interaction was found between message frame and environmental attitude. Implications for social marketers engaged in the promotion of pro-environmental behaviours are discussed.
