With the increasing use of social media, the occurrence of cyber crimes on social media has also increased. In this paper, we focus on online sexual harassment among various cyber crimes and discuss how social media users use social media to avoid online sexual harassment. Drawing on threat avoidance theory, the factors affecting avoidance motivation were identified. Avoidance motivation was measured based on the affordance of social media, and the influence of the degree of sexualization was tested to examine how environmental factors affect motivation behavior. The results indicated that the more users perceived sexualization on social media, the lower their motivation to avoid sexual harassment. Thus, it is important to create an atmosphere on social media where crime is minimized, and users are able to respond appropriately by continuously managing their accounts on these platforms.

The Internet and all of its possibilities and applications have changed individuals' lifestyles in relation to socializing, working, and how they spend their leisure time. Social networking sites (SNSs), such as Facebook or Instagram, are ideal settings for interacting with others but, unfortunately, they are also ideal settings for motivated offenders to commit cybercrimes. Thus SNS users may be more vulnerable to cybercrime. The purpose of this study is to investigate the occurrence of cybercrime victimization, specifically cyber-harassment, cyber-impersonation, and hacking. Self-report surveys collected from a sample of 147 respondents were examined using the moderated multiple regression analysis and a logistic regression analysis to determine possible relationships between SNS lifestyle exposure activities and cybercrime victimization. The results indicate moderate support for the application of lifestyle-routine activity theory (LRAT) to cybercrime victimization. Possible educational and managerial implications, as well as suggestions for future research, are discussed.

Text mining (TM) is most widely used to process the various unstructured text documents and process the data present in the various domains. The other name for text mining is text classification. This domain is most popular in many domains such as movie reviews, product reviews on various E-commerce websites, sentiment analysis, topic modeling and cyber bullying on social media messages. Cyber-bullying is the type of abusing someone with the insulting language. Personal abusing, sexual harassment, other types of abusing come under cyber-bullying. Several existing systems are developed to detect the bullying words based on their situation in the social networking sites (SNS). SNS becomes platform for bully someone. In this paper, An Enhanced text mining approach is developed by using Ensemble Algorithm (ETMA) to solve several problems in traditional algorithms and improve the accuracy, processing time and quality of the result. ETMA is the algorithm used to analyze the bullying text within the social networking sites (SNS) such as facebook, twitter etc. The ETMA is applied on synthetic dataset collected from various data a source which consists of 5k messages belongs to bullying and non-bullying. The performance is analyzed by showing Precision, Recall, F1-Score and Accuracy.

The popularity of social networking sites (SNS) has facilitated communication between users. The usage of SNS helps users in their daily life in various ways such as sharing of opinions, keeping in touch with old friends, making new friends, and getting information. However, some users misuse SNS to belittle or hurt others using profanities, which is typical in cyberbullying incidents. Thus, in this study, we aim to identify profane words from the ASKfm corpus to analyze the profane word distribution across four different roles involved in cyberbullying based on lexicon dictionary. These four roles are: harasser, victim, bystander that assists the bully, and bystander that defends the victim. Evaluation in this study focused on occurrences of the profane word for each role from the corpus. The top 10 common words used in the corpus are also identified and represented in a graph. Results from the analysis show that these four roles used profane words in their conversation with different weightage and distribution, even though the profane words used are mostly similar. The harasser is the first ranked that used profane words in the conversation compared to other roles. The results can be further explored and considered as a potential feature in a cyberbullying detection model using a machine learning approach. Results in this work will contribute to formulate the suitable representation. It is also useful in modeling a cyberbullying detection model based on the identification of profane word distribution across different cyberbullying roles in social networks for future works.

The purpose of this study was to analyze the differences in dating violence perception of dating violence perception of university students. As a research tool, CTS2 was used as a measure of dating violence, a measure developed by Kim(1999) was used, and a measure of dating violence by Jeong(2013) was used. Data analysis was performed using independent sample t-test and multi-variate analyses. The results are summarized as follows. First, female students showed higher differences in total violence against violence and psychological violence than boys, while boys showed higher physical violence than girls. Health majors were significantly higher in total dating violence and psychological violence than students in humanities and social sciences. There was no significant difference in dating violence offenses with or without sexual experience. Only psychological violence showed an interaction effect between gender and sex experience. Second, female students were significantly higher than male students with significant differences in recognition and sub-factors. Health majors were significantly higher in both date violence perception and lower factors than humanities and social sciences. Students without sexual experience perceived overall dating violence more than students with sexual, physical and cyber violence being significantly higher.
