Discourse-aware rumour stance classification in social media using sequential classifiers

Rumour stance classification, defined as classifying the stance of specific social media posts into one of supporting, denying, querying or commenting on an earlier post, is becoming of increasing interest to researchers. While most previous work has focused on using individual tweets as classifier inputs, here we report on the performance of sequential classifiers that exploit the discourse features inherent in social media interactions or ‘conversational threads’. Testing the effectiveness of four sequential classifiers – Hawkes Processes, Linear-Chain Conditional Random Fields (Linear CRF), Tree-Structured Conditional Random Fields (Tree CRF) and Long Short Term Memory networks (LSTM) – on eight datasets associated with breaking news stories, and looking at different types of local and contextual features, our work sheds new light on the development of accurate stance classifiers. We show that sequential classifiers that exploit the use of discourse properties in social media conversations while using only local features, outperform non-sequential classifiers. Furthermore, we show that LSTM using a reduced set of features can outperform the other sequential classifiers; this performance is consistent across datasets and across types of stances. To conclude, our work also analyses the different features under study, identifying those that best help characterise and distinguish between stances, such as supporting tweets being more likely to be accompanied by evidence than denying tweets. We also set forth a number of directions for future research.     

Literacy learning as cruelly optimistic: recovering possible lost futures through transmedial storytelling

In this article, we “think with” theories of affect and transmedial storytelling to explore the cruel optimism that standardised reading pedagogies (e.g. read alouds; leveled readers/independent reading) can produce for readers. We draw on particular moments in a first grade classroom to argue that such pedagogies transmit “normalizing” affects that promise upward mobility, college and career readiness/success, classroom community, and happiness but instead produce literate identities, which cruelly reinforce the racialised, gendered and classist myth of meritocracy. According to Blackman (2019), cruel optimism is harmful because it normalises particular fictions and fantasies that are presented as scientific truths without acknowledging that these dominant stories are but one narrative, thereby closing off other ways of knowing, being and doing. This work offers pedagogical possibilities for bodies that are often read as unsuccessful (e.g. disengaged and struggling) and/or successful (e.g. happy and engaged) and explains how the guise of optimism can fail to acknowledge the larger social, political and economic forces at play. These forces shape the unfolding of academic realities that are simultaneously connected to the past, present and future.

Intelligence and Achievement: A Behavioral Genetic Perspective

Understanding the etiology and relationship between standardized intelligence and academic achievement tests is essential, given their ever-increasing role in American education. Behavioral genetic studies have examined the genetic and environmental etiology of intelligence, academic achievement, and their relationship. Results suggest that genetic, shared environmental, and nonshared environmental influences have an impact on intelligence and academic achievement. Behavioral genetic studies also suggest that the importance of genes may vary as a function of age. Other studies suggest that genes drive the correlation and that the nonshared environment drives the discrepancy between measures of intelligence and achievement. Implications for the identification of intellectually and academically relevant environmental influences are discussed.     

Attuning to In-the-Red Frequencies with/in Readers Workshop

In this article, we ‘think with’ the theoretical concepts of flow, rupture, layering, and sampling to affectively attune to ‘in-the-red frequencies’ flowing across/with-in a New York City primary classroom—that is, alternative sonic frequencies that trouble and refuse hegemonic literacy practices. These hip-hop concepts theorise affect in relation to Black intellectual frameworks for moving, feeling, and sounding. Such frameworks honour philosophical practices emerging from Black people's lived experiences—practices that, historically, have been perceptually coded out of legibility by white supremacist institutions. Ultimately, we argue that thinking with flow↔rupture↔layering↔sampling enables more equitable practices that push literacies ‘into the red,’ namely, by respecting multiple perspectives, histories, and truths; accounting for power, privilege, positioning, and complicity; and highlighting ‘otherwise’ social worlds not predicated on hegemonic whiteness, anti-blackness, and socio-political violence.     

Sexual and reproductive health information sources preferred by out-of-school adolescents in rural southwest Uganda

This paper defines how out-of-school adolescents from Masaka District in rural southwest Uganda currently receive sexual and reproductive health information and how they would prefer to receive that information. Information adolescents feel they lack falls into three broad categories: sexual and reproductive health issues, the negotiation of sex and sexual relationships, and making the transition to adulthood. The preferred source for information depends on the type of information to be delivered, the overriding principle being that the source must be authoritative in that type of information. Current information sources including family, peers and media are perceived as either flawed or insufficient. Preferable sources fall into three categories based on the type of information provided: accurate sexual and reproductive health information should come from trained community and media-based rather than clinic-based health educators; information about negotiation of good relationships and the negotiation of sex and condom use within relationships should come from an up-skilled traditional source, ssenga (paternal aunt), particularly for young women; and social information about becoming a good adult should come from parents, grandparents, church and community leaders. All information should be positively framed and non-judgemental. Centrally coordinated community health promotions delivered by trained community-based health educators, ssenga and parents, guided and supported by existing radio and print media, are required.
