What About Us

Why Men Rebel was first published in 1970 on the heels of a decade of political violence and protest not only in remote corners of Africa and Southeast Asia, but also at home in the United States. Forty years later, the world is riveted on uprisings in the Middle East, and the United States has been overtaken by a focus on international terrorism and a fascination with citizen movements at home and abroad. Do the arguments of 1970 apply today? Why Men Rebel lends new insight into contemporary challenges of transnational recruitment and organization, multimedia mobilization, and terrorism.

Against our will: Men, women, and rape

Hate speech is commonly defined as any communication that disparages a target group of people based on some characteristic such as race, colour, ethnicity, gender, sexual orientation, nationality, religion, or other characteristic. Due to the massive rise of user-generated web content on social media, the amount of hate speech is also steadily increasing. Over the past years, interest in online hate speech detection and, particularly, the automation of this task has continuously grown, along with the societal impact of the phenomenon. This paper describes a hate speech dataset composed of thousands of sentences manually labelled as containing hate speech or not. The sentences have been extracted from Stormfront, a white supremacist forum. A custom annotation tool has been developed to carry out the manual labelling task which, among other things, allows the annotators to choose whether to read the context of a sentence before labelling it. The paper also provides a thoughtful qualitative and quantitative study of the resulting dataset and several baseline experiments with different classification models. The dataset is publicly available.

Despite the Canadian Security Intelligence Service's recent concern with the growing threat from right-wing extremists nationwide, we have little contemporary scholarship on the far right movement in Canada and fewer attempts to systematically analyze their ideologies and activities. Drawing on a three-year study involving interviews with Canadian law enforcement officials, community organizations, and right-wing activists, as well as analyses of open source intelligence, this article examines the endogenous factors that facilitate and inhibit the right-wing extremist movement in Canada. Findings suggest that strengths and weaknesses of the groups themselves can be exploited as a means of debilitating them.

Uneasy Alliances: A Look at the Right-Wing Extremist Movement in Canada

As violent extremists continue to surface in online discussion forums, law enforcement agencies search for new ways of uncovering their digital indicators. Researchers have both described and hypothesized a number of ways to detect online traces of potential extremists, yet this area of inquiry remains in its infancy. This study proposes a new search method that, through the analysis of sentiment, identifies the most radical users within online forums. Although this method is applicable to web-forums of any type, the method was evaluated on four Islamic forums containing approximately 1 million posts of its 26,000 unique users. Several characteristics of each user’s postings were examined, including their posting behavior and the content of their posts. The content was analyzed using Parts-Of-Speech tagging, sentiment analysis, and a novel algorithm called ‘Sentiment-based Identification of Radical Authors’, which accounts for a user’s percentile score for average sentiment score, volume of negati...
