Detecting Important Life Events on Twitter Using Frequent Semantic and Syntactic Subgraphs

Identifying global events from social media has been the focus of much research in recent years. However, the identification of personal life events poses new requirements and challenges that have received relatively little research attention. In this paper we explore a new approach for life event identification, where we expand social media posts into both semantic, and syntactic networks of content. Frequent graph patterns are mined from these networks and used as features to enrich life-event classifiers. Results show that our approach significantly outperforms the best performing baseline in accuracy (by 4.48% points) and F-measure (by 4.54% points) when used to identify five major life events identified from the psychology literature: Getting Married, Having Children, Death of a Parent, Starting School, and Falling in Love. In addition, our results show that, while semantic graphs are effective at discriminating the theme of the post (e.g. the topic of marriage), syntactic graphs help identify whether the post describes a personal event (e.g. someone getting married)

Implicit learning of recursive context-free grammars

Context-free grammars are fundamental for the description of linguistic syntax. However, most artificial grammar learning experiments have explored learning of simpler finite-state grammars, while studies exploring context-free grammars have not assessed awareness and implicitness. This paper explores the implicit learning of context-free grammars employing features of hierarchical organization, recursive embedding and long-distance dependencies. The grammars also featured the distinction between left- and right-branching structures, as well as between centre- and tail-embedding, both distinctions found in natural languages. People acquired unconscious knowledge of relations between grammatical classes even for dependencies over long distances, in ways that went beyond learning simpler relations (e.g. n-grams) between individual words. The structural distinctions drawn from linguistics also proved important as performance was greater for tail-embedding than centre-embedding structures. The results suggest the plausibility of implicit learning of complex context-free structures, which model some features of natural languages. They support the relevance of artificial grammar learning for probing mechanisms of language learning and challenge existing theories and computational models of implicit learning

Despite an increase in the number of women entering ‘male’ workplaces, gendered occupational stereotypes continue to endure as they are so deeply entrenched within community. Furthermore, even with frequent government initiatives, men’s numbers are not increasing in ‘female’ occupations such as teaching as these jobs persistent to be seen as only suitable for those with ‘feminine’ characteristics. Fewer than 15 percent of United Kingdom (U.K.) primary school teachers are male. De-stereotyping this work role is therefore of key importance as we need more qualified teachers in the U.K. To date, there has been relatively little research into the linguistic behaviour of men working in primary school teaching. To address this gap, this current paper focuses on men’s discursive behaviour in the occupation of teaching in an attempt to begin to de-stereotype this profession through an exploration of how the job is actually performed through language to assess whether teacher gender affects teaching strategies utilised in the classroom. This paper reports on the qualitative findings from an exploratory case study that examines male and female primary school teachers’ linguistic strategies in teacher-led class instruction. To provide empirical insights into how this work-role practice is performed, this paper focuses on the oral feedback given by the teacher to pupils to examine how they use follow-up strategies. Data collected by 12 teachers across 4 schools in Hertfordshire in the U.K. was explored using Interactional Sociolinguistics and a social constructionist perspective. Results demonstrate both female and male teachers actively constructing a context-dependent teaching identity, with their language breaking stereotypical gendered norms of speaking. The discursive behaviour of these teachers should therefore not be described as ‘feminine’ or ‘masculine’, but rather labelled as the discourse of doing ‘being’ a teacher. They are using the unmarked speech styles in this environment as the work role guides, shapes and permeates their discursive choices. Arguably then, gender is not an overriding variable here in being a teacher. These findings lend support to the current ongoing debate for the imperative need to de-gender how we think about language use, occupations, and the skills and characteristics one is assumed to have simply because of their gender. Men often decide against becoming a primary teacher because they think it is a female profession. We must re-interpret language use as reflecting professional identity rather than gender identity. By raising awareness of primary school teachers’ linguistic behaviour, we may start to take steps towards de-gendering the job for only then may we see more men taking up such professional occupations. This research has important implications for U.K government incentives which currently try to recruit men by stressing that they are needed for hegemonic ‘masculine’ reasons, which only serves to strengthen gender stereotypes.Peer reviewe

Opening New Doors: Hands-On Participation Brings A New Audience to the Clay Studio

This case study examines how The Clay Studio, a ceramic-arts studio, gallery and shop in Philadelphia, attracted younger audiences to its workshops and exhibits. In 2007, the studio became concerned that its audience was getting older and few newcomers were signing up for classes or making purchases. The studio then sought to engage younger professionals ages 25 to 45. Audience research helped identify elements of activities that could attract younger professionals, including flexible schedules, shorter courses and the ability to socialize. The studio therefore added new experiences such as "Date Night," a Friday evening event where novices could experiment with clay in an informal environment. It also redesigned its website and print materials to emphasize the visitor experience rather than the skills participants might learn.Five years later, the number of students taking classes tripled and revenue from the school more than doubled. Monthly workshops regularly sell out, and many newcomers have gone on to take longer classes.But challenges remain. The organization must now balance the needs and desires of long-time students and collectors, who want to see the more serious side of Clay, with those of the newcomers, many of whom prefer a more social, informal experience.This publication is part of a set of case studies and reports looking at the efforts of arts organizations that received Wallace Excellence Awards to reach new audiences and deepen relationships with current ones. In three accompanying videos, Clay Studio president Chris Taylor and Magda Martinez, the program director of Fleisher Art Memorial, another Philadelphia arts organization that received a Wallace Excellence Award, discuss their audience-building efforts

The influence of school and teaching quality on children’s progress in primary school

This report investigates the way school and classroom processes affect the cognitive progress and social/behavioural development of children between the ages of 6 (Year 1) and 10 (Year 5) in primary schools in England. The research is part of the larger longitudinal study of Effective Pre-School and Primary Education (EPPE 3-11) funded by the Department for Children, Schools and Families (DCSF) that is following children’s cognitive and social/behavioural development from ages 3 to 11 years. The EPPE 3-11 study investigates both pre-school and primary school influences on children’s attainment, progress and social/behavioural development. This report describes the results of quantitative analyses based on a subsample of 1160 EPPE children across Year 1 to 5 of primary education. The research builds on the earlier analyses of children’s Reading and Mathematics attainments and social/behavioural outcomes in Year 5 for the full EPPE 3-11 sample (see Sammons, 2007a; 2007b), by investigating relationships between children’s outcomes and measures of classroom processes, collected through direct observation of Year 5 classes in 125 focal schools chosen from the larger EPPE 3-11 data set. The analyses also explore patterns of association between children’s outcomes and broader measures of overall school characteristics derived from teacher questionnaires and Ofsted inspection reports for this sub-sample of schools
