The Discourse of Digital Deceptions and â419â Emails
This study applies a computer-mediated discourse analysis
(CMDA) to the study of discourse structures and functions of â419â emails â the Nigerian term for online/financial fraud. The hoax mails are in the form of online lottery winning announcements, and email âbusiness proposalsâ
involving money transfers/claims of dormant bank accounts overseas. Data comprise 68 email samples collected from the researcherâs inboxes and colleaguesâ and studentsâ mail boxes between January 2008 and March 2009 in Ota, Nigeria. The study reveals that the writers of the mails apply
discourse/pragmatic strategies such as socio-cultural greeting formulas,self-identification, reassurance/confidence building, narrativity and action
prompting strategies to sustain the interest of the receivers. The study also shows that this genre of computer-mediated communication (CMC) has become a regular part of our Internet experience, and is not likely to be extinct in the near future as previous studies of email hoaxes have predicted. It is believed that as the global economy witnesses a recession, chances are that more creative and complex ways of combating the situation will arise.
Economic hardship has been blamed for fraud/online scams, inadvertently prompting youths to engage in various anti-social activities. K E Y W O R D S : computer-media communication, deceptions, discourse,

Building a document genre corpus: a profile of the KRYS I corpus
This paper describes the KRYS I corpus, consisting of documents classified into 70 genre classes. It has
been constructed as part of an effort to automate document genre classification as distinct from topic
detection. Previously there has been very little work on building corpora of texts which have been classified
using a nontopical
genre palette. The reason for this is partly due to the fact that genre as a concept, is
rooted in philosophy, rhetoric and literature, and highly complex and domain dependent in its interpretation
([11]). The usefulness of genre in everyday information search is only now starting to be recognised and
there is no genre classification schema that has been consolidated to have applicable value in this direction.
By presenting here our experiences in constructing the KRYS I corpus, we hope to shed light on the
information gathering and seeking behaviour and the role of genre in these activities, as well as a way
forward for creating a better corpus for testing automated genre classification tasks and the application of
these tasks to other domains.

High-level feature detection from video in TRECVid: a 5-year retrospective of achievements
Successful and effective content-based access to digital
video requires fast, accurate and scalable methods to determine the video content automatically. A variety of contemporary approaches to this rely on text taken from speech within the video, or on matching one video frame against others using low-level characteristics like
colour, texture, or shapes, or on determining and matching objects appearing within the video. Possibly the most important technique, however, is one which determines the presence or absence of a high-level or semantic feature, within a video clip or shot. By utilizing dozens, hundreds or even thousands of such semantic features we can support many kinds of content-based video navigation. Critically however, this depends on being able to determine whether each feature is or is not present in a video clip.
The last 5 years have seen much progress in the development of techniques to determine the presence of semantic features within video. This progress can be tracked in the annual TRECVid benchmarking activity where dozens of research groups measure the effectiveness of their techniques on common data and using an open, metrics-based approach. In this chapter we summarise the work
done on the TRECVid high-level feature task, showing the
progress made year-on-year. This provides a fairly comprehensive statement on where the state-of-the-art is regarding this important task, not just for one research group or for one approach, but across the spectrum. We then use this past and on-going work as a basis for highlighting the trends that are emerging in this area, and the questions which remain to be addressed before we can
achieve large-scale, fast and reliable high-level feature detection on video
"Il parle normal, il parle comme nousâ: self-reported usage and attitudes in a banlieue
We report on a survey of language attitudes carried out as part of a project comparing youth language in Paris and London.
As in similar studies carried out in London (Cheshire et al. 2008), Berlin (Wiese 2009) and elsewhere (Boyd et al. 2015), the focus was on features considered typical of âcontemporary urban vernacularsâ (Rampton 2015).
The respondents were pupils aged 15-18 in two secondary schools in a working-class northern suburb of Paris. The survey included (1) a written questionnaire containing examples of features potentially undergoing change in contemporary French; (2) an analysis of reactions to extracts from the project data: participants were asked to comment on the speakers and the features identified.
Quantitative analysis had shown that some of these features are more widespread than others and are used by certain categories of speaker more than others (Gardner-Chloros and Secova, 2018). This study provides a qualitative dimension, showing that different features have different degrees of perceptual salience and acceptability. It demonstrates that youth varieties do not involve characteristic features being used as a âpackageâ, and that such changes interact in a complex manner with attitudinal factors. The study also provides material for reflection on the role of attitude studies within sociolinguistic surveys
The impact of a multi-strategy academic writing handbook on Emergent bilingualsâ cross-curricular writing competences
La escritura acadĂ©mica en una segunda lengua puede ser uno de los requerimientos mĂĄs complejos en la educaciĂłn superior debido a los elementos lingĂŒĂsticos, estratĂ©gicos y procedimentales que esta abarca al igual que los procesos cognitivos superiores que involucra. A pesar de su presencia permanente en la academia, los profesores no han encontrado aĂșn una forma apropiada para enseñar y evaluar la escritura que garantice el progreso de los estudiantes y el apoyo continuo a lo largo de su proceso de aprendizaje. De esta manera, este estudio de caso de mĂ©todos mixtos apunta a diseñar y evaluar la efectividad de un Manual de Referencia para la Escritura AcadĂ©mica (MREA) que pretende proveer la asistencia constante que los estudiantes necesitan para solidificar su conocimiento de escritura y el material pedagĂłgico apropiado que los docentes requieren para unificar los prĂĄcticas de enseñanza y evaluaciĂłn de la escritura; este manual estĂĄ fundamentado en los enfoques de la escrita como proceso y basada en el gĂ©nero, anĂĄlisis de errores y evaluaciĂłn..
