Various methods have already been implemented to handle the issue, but the embezzlers have always managed to employ innovative tactics to circumvent a number of security measures and execute the fraudulent transactions. Thus, instead of a rule-based system, an intelligent and adaptable machine learning based algorithm should be an answer to tackle such sophisticated digital theft. The presented framework uses k-NN for classification and utilises Principal Component Analysis (PCA) for raw data transformation. Neighbours (anomalies in data) were created using Synthetic Minority Oversampling Technique (SMOTE) and a distance-based feature selection method was employed. The proposed process performed well by having a precision and F-Score of 98.32% and 97.44% respectively for k-NN and 100% and 98.24% respectively for Time subset when using the misclassified instances. This work also demonstrates a larger and clearer classification breakdown, which aids in achieving higher precision rate and improved recall rate. In a view to accomplish such high accuracy, the original datum was transformed using Principal Component Analysis (PCA), neighbours (anomalies in data) were created using Synthetic Minority Oversampling Technique (SMOTE) and a distance based feature selection method was employed. The proposed process performed well when using the misclassified instances in the test dataset used in the previous work, while demonstrating a larger and clearer classification breakdown.

A web-based survey was conducted using South Korean consumers (n=528). The results showed that performance expectancy and social influence had a positive effect on intention to use MPS, whereas privacy risk had a negative effect on intention to use MPS. Gender was found to moderate two paths in the model, such that a high level of facilitating conditions increased intention to use MPS for males but not for females, whereas privacy risk decreased intention to use MPS for females but not for males. Theoretical and managerial implications for researchers and marketing practitioners are then discussed.

A laboratory experiment was adopted to evaluate the advertising effectiveness of two types of mobile advergame. Under randomly assigned experimental conditions, 152 people were assigned to competitive advergames which emphasizes on the efficiency of user to complete the task, and 143 people were assigned to social advergames which emphasizes the user's task is repetitive, and even communicates with other users and collaborates to finish a goal. The results indicated that mobile competitive and social advergames exert distinct effects on advertising effectiveness. Specifically, competitive advergames enhance game attitude, whereas social advergames promote brand recall. The results also indicated that both competitive and social advergames are highly effective tools for enhancing brand attitude. The results assist in filling research gaps regarding the effect of mobile advergame type on advertising effectiveness.

To further clarify this mechanism, we perform a longitudinal survey to investigate the direct effects of consumer characteristics on online purchase preference, and the moderating effects of these characteristics on the influences of two online purchase goals (saving money and saving time) on purchase outcomes. Customers personal characteristics in this study mainly include gender difference, income, age, education, work status, and experience of online shopping. The results show that only age and online experience have direct effects on consumers’ online purchase preference. By contrast, an important finding suggests that most of those personal characteristics affect purchase outcomes mainly through moderating the preference effects of the two online purchase goals, rather than directly influencing purchase preferences. Management implications and future research directions are also presented at the end of the paper. To cite this document: Zhen Li and Avus CY.

The types of advertising on social media sites are becoming more diverse. The newest type of advertising is native advertising, and it is more effective than traditional advertising. However, there are few studies of the effect of social advertising. This study establishes an optimum combination of advertising types and products on social media. Its framework measures the effects of social advertising on social media advertising types, products and consumers’ behavior. Enterprises and marketers can use these findings to make decisions about social media. A web survey will be administered to collect samples. ANOVA will be used to compare the effectiveness of different kinds of social media advertising. This study will use these results as a basis for in-depth discussions of social marketing effects via several platforms and product types. Conclusions and implications will be also discussed.

At the same time, the number of foreign students studying Mandarin in Taiwan is increasing. However, there is no research on and discussion of factors affecting these students’ continuance intention in Taiwan’s mobile telecommunications industry. This study therefore uses the theory of planned behavior (TPB) and the expectancy disconfirmation model (EDM) to explain the factors affecting foreign students’ intention to continue using mobile telecommunications services. A web-based questionnaire survey is used to collect the primary data, and structural equation modeling (SEM) is used to test the proposed research model. The empirical results find that the three constructs of TPB (i.e. attitude, subjective norms, and perceived behavioral control) and the satisfaction construct of EDM have a significant and positive impact on foreign students’ continuance intention toward mobile telecommunications services. This study will enable Taiwan’s mobile telecommunications companies to adjust their marketing strategies to increase foreign students’ continuance intention.

To address the research gap regarding spokescharacters, this study examined the rarely discussed influence of lip synchronization on online advertisements. This study tested the effects of different types of virtual character on advertising effectiveness, which was measured according to ad credibility, attitude toward the ad, and attention toward the ad. The primary experiment included 8 conditions in which each character had a different gender (male vs. female), facial appearance (human-like vs. cartoon-like), and lip synchronization (adult vs. child), thereby representing a hedonic animated online advertisement. By using an analysis of variance, this study revealed that cartoon-like female spokescharacters with child lip synchronization exhibited the highest effectiveness in online advertisements.

Although ICT has been determined as a tool to enhance academic performance in the past, recent studies discuss the negative consequences of ICT addiction among students. ICT addiction has subsequently led to a new dilemma: whether or not to allow students to access ICT. This study attempts to identify the mediating factor(s) between the use of ICT and learning performance of students. In this research, data has been collected from a sample of 336 students studying business management at different universities in Bangladesh. The study applied the partial least squares (PLS) and structural equation modeling (SEM) tools to identify the factors that influence learning performance. The statistical results confirm that academic self-efficacy strengthens the relationship between the use of the Internet and learning performance. The outcome also identifies that professional Internet use is a stronger predictor of learning performance than general Internet use. These findings are useful for educators, policymakers, parents, and practitioners to enhance students’ learning performance in Bangladeshi universities. The paper concludes by suggesting avenues for future research.","PeriodicalId":38305,"journal":{"name":"International Journal of Electronic Commerce Studies","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48853087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The security mechanism of Android is based on an instrument that gives users the information about permissions that the application requests before installing it. This authorization system provides an overview of the application, and this can help to raise awareness of its risks. However, standard users still do not have enough information to understand clearly these requested authorizations and their implications on their security. In this article, we present a tool called “Permission watcher” that combines dynamic and static analysis. Our proposed tool allows users to install any application with only the necessary permissions instead of accepting all permissions requested or cancel the installation completely.
