Most Text to Speech (TTS) systems today assume that the input text is in a single language and is written in the same language that the text needs to be synthesized in. However, in bilingual and multilingual communities, code mixing or code switching occurs in speech, in which speakers switch between languages in the same utterance. Due to the popularity of social media, we now see code-mixing ...

In the summer of 2013, Brazil experienced a period of conflict triggered by a series of protests. While the popular press covered the events, little empirical work has investigated how first-hand reporting of the protests occurred and evolved over social media and how such exposure in turn impacted the demonstrations themselves. In this study we examine over 42 million tweets shared during the ...

Over recent years there has been a worldwide trend towards smaller government government departments being under increased pressure to privatise or outsource parts of their operation and to move towards a more independent corporatised model. The corporatised model is seen to involve the organisation moving away from being a direct arm of the government, acting more as a business entity in their...

Network theory is finding applications in the life and social sciences for ecology, epidemiology, finance and social-ecological systems. While there are methods to generate specific types of networks, the broad literature is focused on generating unweighted networks. In this paper, we present a framework for generating weighted networks that satisfy user-defined criteria. Each criterion hierarc...

Reenements of Sanov's large deviations theorem lead via Csiszz ar's information theoretic identity to reenements of the Gibbs conditioning principle which are valid for blocks whose length increase with the length of the conditioning sequence. Sharp bounds on the growth of the block length with the length of the conditioning sequence are derived. Extensions of Csiszz ar's triangle inequality an...

More and more of the information on the web is dialogic, from Facebook newsfeeds, to forum conversations, to comment threads on news articles. In contrast to traditional, monologic resources such as news, highly social dialogue is very frequent in social media, as illustrated in the snippets in Fig. 1 from the publicly available Internet Argument Corpus (IAC) (Walker et al., 2012). Utterances a...

Mobile robotic applications have to deal with limited resources and variable execution conditions that must be appropriately managed in order to keep an acceptable system behavior. This requires the implementation of runtime adaptation mechanisms that monitor continuously system state and module the resulting performance as a function of the available resources. As we consider that these adapta...

In this work, the geometric relation between space time block code design for the coherent channel and its noncoherent counterpart is exploited to get an analogue of the information theoretic inequality I(X;S) I((X;H);S) in terms of diversity. It provides a lower bound on the performance of non-coherent codes when used in coherent scenarios. This leads in turn to a code design decomposition res...

OBJECTIVE Despite social environmental factors such as deprivation, urbanicity, migration and adversity being established risk factors for psychotic disorders, there is a paucity of knowledge on the influence of social environmental risk factors in the UHR population. Firstly, we aimed to investigate the association between social deprivation and risk of transition and secondly, we aimed to inv...

Within communities knowledge is shared regularly. Although today’s communities can rely on sophisticated collaboration technologies, the sharing of knowledge remains impeded by different social mechanisms. Removing impediments that originate from different understandings between knowledge exchanging individuals has been called boundary management by Carlile. Boundary management can be supported...
