71	以推敲可能性模式探討影響評論幫助性之因素 / Factors Affecting Review Helpfulness : An Elaboration Likelihood Model Perspective 熊耿得, Hsiung, Keng-Te Unknown Date (has links) 在電子商務中，評論會影響消費者的購買決策，透過評論幫助性可以篩選出關鍵的評論，以利消費者進行決策。本研究以推敲可能性模式作為研究架構，透過文字探勘挖掘評論的文本特性來探討影響幫助性之要素，中央線索除了評論長度與可讀性外，利用LDA主題模型衡量評論主題廣度；周邊線索則是透過環狀情緒模型進行情感分析，並透過評論者排名來衡量來源可信度，利用亞馬遜商店中的資料進行驗證分析。結果發現，消費者在判斷評論幫助性時，會參考中央以及周邊線索。具備高論點品質的中央線索將有效提升評論幫助性；周邊線索整體而言，證實了社會中存在負向偏誤，具備喚起度的負向情感較容易提升評論幫助性，而評論是否被認為有幫助確實會受到評論者的排名所影響。進階分析結果顯示，周邊的情感效果會受到評論者排名高低的影響，前段評論者應保持中立避免帶有個人情緒；中段評論者的評論幫助性會隨著情緒喚起度而增加；後段評論者則需要增加自身的負向情感，才能夠對於評論幫助性有正向影響。 / Online reviews are important factors in consumers’ purchase decision. The helpfulness of reviews allows consumers to quickly identify useful reviews. The purpose of this study is to investigate the nature of online reviews that affect their helpfulness through the lens of the elaboration likelihood model. For the central cues, we adopt latent dirichlet allocation to measure review breadth in addition to review length and review readability. For the peripheral cues, we use the sentiment analysis based on the circumplex model to catch the emotion effect and use the ranking of the reviewers to measure the source credibility. We used a dataset collected from Amazon.com to evaluate our model. The result suggests that consumers focus both central and peripheral cues when they read reviews. Consumers care about the length, breadth and readability of reviews associated with the central route, and the emotional effects associated with the peripheral route. In the advanced research, we split our sample into 3 groups by their ranking of the reviewers. We found that the top reviewers should keep neutral and avoid personal feelings to make their reviews more helpful; the middle reviewers can use more arousal words to improve their review helpfulness; the bottom reviewers must increase their emotional valence strength, especially the negative emotion to higher the perceived review helpfulness. 評論幫助性推敲可能性模式 LDA主題模型環狀情緒模型情感分析 Review helpfulness Elaboration likelihood model Latent dirichlet allocation Circumplex model Sentiment analysis
72	EXPLORING PHISHING SUSCEPTIBILITY ATTRIBUTABLE TO AUTHORITY, URGENCY, RISK PERCEPTION AND HUMAN FACTORS Priyanka Tiwari (9187496) 30 July 2020 (has links) <p>Security breaches nowadays are not limited to technological orientation. Research in the information security domain is gradually shifting towards human behavioral orientation toward breaches that target weaknesses arising from human behaviors (Workman et al., 2007). Currently, social engineering breaches are more effective than many technical attacks. In fact, the majority of cyber assaults have a social engineering component. Social Engineering is the art of manipulating human flaws towards a malicious objective (Breda et al., 2017). In the likely future, social engineering will be the most predominant attack vector within cyber security (Breda et al., 2017). Human failures, persuasion and social influences are key elements to understand when considering security behaviors. With the increasing concerns for social engineering and advancements in human factors-based technology, phishing emails are becoming more prevalent in exploiting human factors and external factors. Such factors have been researched upon in pairs, not overall. Till date, there is not much research done to identify the collaborative links between authority, urgency, risk perception and human factors such as personality traits, and knowledge. This study investigates about phishing email characters, external influences, human factors influences, and their collaborative effects. </p> Social and Community Informatics Computer-Human Interaction Social Engineering attacks Cyber Security Personality Traits Social Engineering Phishing Spear phishing Personality Framework Authority Urgency Risk Perception Cyber knowledge Elaboration Likelihood Model Human factors User susceptibility
73	Adoption of sustainable forestry practices by Non-Industrial Private Forest owners in Virginia Rasamoelina, Maminiaina Solonirina 01 July 2008 (has links) The concept of Sustainable Forest Management (SFM) has been promoted in the past few decades all over the world. Non-industrial private forest (NIPF) owners play an important role in that aspect in the U.S. because of their number (about 16 millions), the size of forest land under their control (about half of all forest land in the continental US), and the dynamism of their population (increasing number of new owners). This study sought to better understand how NIPF owners come to a decision for adoption (or non-adoption) of SFM practices. We developed a theoretical model combining four theories (the Value-Belief-Norm theory, the Theory of Planned Behavior, the Elaboration Likelihood Model, and the Innovation-Diffusion Process) to explain NIPF's decision making. Using multivariate analyses, we determined which elements of the developed theoretical model were significant in explaining adoption of eight groups of practices. Overall, some of the most significant predictors of adoption we identified were technical assistance, motivations for owning land and the use of a written management plan. Particular attention was also directed toward the eventual relationship between education and adoption of SFM practices and it was found that NIPF owners who attended educational programs tended to be likely adopters compared to those who did not attend any educational program. Since SFM was not limited to the US, we also analyzed the concept of SFM with the same goals as in the US, but under a completely different context (socio-cultural, economic and ecologic) in Africa, through the community-based natural resource management (CBNRM) system. We used four case studies and focused on criteria such as participation, equity (both procedural and distributive, power devolution, trust, etc) to analyze how CBNRM works on the field, what lessons to take from the cases to better ensure the goal of sustainability of the resources. / Ph.

76	Adolescent Interest in Alcohol Responsibility Messages: The Message Matters John, Kevin Kimball 12 November 2009 (has links) (PDF) Adolescents are especially vulnerable to image-based messages, which place them directly in line with the lifestyle messages presented in numerous alcohol advertisements. Research has shown that teenagers encounter alcohol advertisements from a variety of sources, prompting concern over the consequences of exposure and the risks associated with teen drinking. Warning messages contained within these alcohol advertisements are often vague in their wording and targeted to promote responsible drinking among adults, making them wholly inadequate for teen deterrence. This thesis explores the problems with current alcohol responsibility messages when dealing with teens, and proposes the development of new, modified messages, that are more direct and consequence-based. The Elaboration Likelihood Model of persuasion was used to describe teen processing of alcohol warning messages, and eye-tracking technology was used to determine how this processing can be examined visually. The purpose of this research was to aid in the development of new messages that have been modified by type size, type contrast, and message content (a 2x2x2 factorial design). Results indicated that modifying message content to include direct language and a consequence enhances visibility and attention to alcohol responsibility messages. Larger type and higher contrast can be applied to the message to further enhance visibility, but the change in attention for these factors was shown to be minimal and nonsignificant. Overall, the greatest power lies in changing the message itself, irrespective of all other variables. eye-tracking eye tracking eye tracking masked recall aided recall elaboration likelihood model elm persuasion alcohol responsibility message warning message message drink responsibly teen teens adolescent advertising advertisements anova factorial design 2x2x2 2 x 2 x 2 corona becks amstel heineken Communication
