Big Data presents many challenges related to volume, whether one is interested in studying past datasets or, even more problematically, attempting to work with live streams of data. The most obvious challenge, in a ‘noisy’ environment such as contemporary social media, is to collect the pertinent information; be that information for a specific study, tweets which can inform emergency services or other responders to an ongoing crisis, or give an advantage to those involved in prediction markets. Often, such a process is iterative, with keywords and hashtags changing with the passage of time, and both collection and analytic methodologies need to be continually adapted to respond to this changing information. While many of the data sets collected and analyzed are preformed, that is they are built around a particular keyword, hashtag, or set of authors, they still contain a large volume of information, much of which is unnecessary for the current purpose and/or potentially useful for future projects. Accordingly, this panel considers methods for separating and combining data to optimize big data research and report findings to stakeholders. The first paper considers possible coding mechanisms for incoming tweets during a crisis, taking a large stream of incoming tweets and selecting which of those need to be immediately placed in front of responders, for manual filtering and possible action. The paper suggests two solutions for this, content analysis and user profiling. In the former case, aspects of the tweet are assigned a score to assess its likely relationship to the topic at hand, and the urgency of the information, whilst the latter attempts to identify those users who are either serving as amplifiers of information or are known as an authoritative source. Through these techniques, the information contained in a large dataset could be filtered down to match the expected capacity of emergency responders, and knowledge as to the core keywords or hashtags relating to the current event is constantly refined for future data collection. The second paper is also concerned with identifying significant tweets, but in this case tweets relevant to particular prediction market; tennis betting. As increasing numbers of professional sports men and women create Twitter accounts to communicate with their fans, information is being shared regarding injuries, form and emotions which have the potential to impact on future results. As has already been demonstrated with leading US sports, such information is extremely valuable. Tennis, as with American Football (NFL) and Baseball (MLB) has paid subscription services which manually filter incoming news sources, including tweets, for information valuable to gamblers, gambling operators, and fantasy sports players. However, whilst such services are still niche operations, much of the value of information is lost by the time it reaches one of these services. The paper thus considers how information could be filtered from twitter user lists and hash tag or keyword monitoring, assessing the value of the source, information, and the prediction markets to which it may relate. The third paper examines methods for collecting Twitter data and following changes in an ongoing, dynamic social movement, such as the Occupy Wall Street movement. It involves the development of technical infrastructure to collect and make the tweets available for exploration and analysis. A strategy to respond to changes in the social movement is also required or the resulting tweets will only reflect the discussions and strategies the movement used at the time the keyword list is created — in a way, keyword creation is part strategy and part art. In this paper we describe strategies for the creation of a social media archive, specifically tweets related to the Occupy Wall Street movement, and methods for continuing to adapt data collection strategies as the movement’s presence in Twitter changes over time. We also discuss the opportunities and methods to extract data smaller slices of data from an archive of social media data to support a multitude of research projects in multiple fields of study. The common theme amongst these papers is that of constructing a data set, filtering it for a specific purpose, and then using the resulting information to aid in future data collection. The intention is that through the papers presented, and subsequent discussion, the panel will inform the wider research community not only on the objectives and limitations of data collection, live analytics, and filtering, but also on current and in-development methodologies that could be adopted by those working with such datasets, and how such approaches could be customized depending on the project stakeholders.

The occasional ArtsHub article asking spectators to show respect for stage by switching all devices off notwithstanding, in the last few years we have witnessed an clear push to make more use of social media as a means by which spectators might respond to a performance across most theatre companies. Mainstage companies, as well as contemporary companies are asking us to turn on, tune in and tweet our impressions of a show to them, to each other, and to the masses – sometimes during the show, sometimes after the show, and sometimes without having seen the show. In this paper, I investigate the relationship between theatre, spectatorship and social media, tracing the transition from print platforms in which expert critics were responsible for determining audience response to today’s online platforms in which everybody is responsible for debating responses. Is the tendency to invite spectators to comment via social media before, during, or after a show the advance in audience engagement, entertainment and empowerment many hail it to be? Is it a return to a more democratised past in which theatres were active, interactive and at times downright rowdy, and the word of the published critic had yet to take over from the word of the average punter? Is it delivering distinctive shifts in theatre and theatrical meaning making? Or is it simply a good way to get spectators to write about a work they are no longer watching? An advance in the marketing of the work rather than an advance in the active, interactive aesthetic of the work? In this paper, I consider what the performance of spectatorship on social media tells us about theatre, spectatorship and meaning-making. I use initial findings about the distinctive dramaturgies, conflicts and powerplays that characterise debates about performance and performance culture on social media to reflect on the potentially productive relationship between theatre, social media, spectatorship, and meaning making. I suggest that the distinctive patterns of engagement displayed on social media platforms – including, in many cases, remediation rather than translation, adaptation or transformation of prior engagement practices – have a lot to tell us about how spectators and spectator groups negotiate for the power to provide the dominant interpretation of a work.

Solving indeterminate algebraic equations in integers is a classic topic in the mathematics curricula across grades. At the undergraduate level, the study of solutions of non-linear equations of this kind can be motivated by the use of technology. This article shows how the unity of geometric contextualization and spreadsheet-based amplification of this topic can provide a discovery experience for prospective secondary teachers and information technology students. Such experience can be extended to include a transition from a computationally driven conjecturing to a formal proof based on a number of simple yet useful techniques.

This chapter focuses on teacher education for high-poverty schools in Australia and suggests that a contextualization of poverty is an important step in identifying solutions to the persistent gaps in how teachers are prepared to teach in schools where they can make a lasting difference. Understanding how poverty looks different between and within different countries provides a reminder of the complexities of disadvantage. Similarities exist within OECD countries; however, differences are also evident. This is something that initial teacher education (ITE) solutions need to take into account. While Australia has a history of initiatives designed to address teacher education for high-poverty schools, this chapter provides a particular snapshot of Australia’s National Exceptional Teachers for Disadvantaged Schools program (NETDS), a large-scale, national partnership between universities and Departments of Education, which is partially supported by philanthropic funding.

Empty Heavens. Georges Bataille and the Question of Religion. The dissertation explores the question of religion in the texts of Georges Bataille (1897 1962), the controversial French avant-garde writer and philosopher. Passionate about religion throughout his life, Bataille devoted to it both critical analyses and personal meditations. In this study, Bataille s multifaceted relationship to religion is interpreted as expressing a passion for radical otherness. Bataille is approached as a characteristically modern thinker who, nevertheless, questions some landmarks of modernity insofar as modernity is interpreted as a triumph of secularization. The dissertation is situated at the intersection of comparative religion and philosophy of religion. Methodologically, the study resorts to theoretical contextualization and concept analysis. Acknowledging that Bataille s writings challenge the assumptions about coherent meaning taken for granted in traditional philosophical analysis, the study also pays attention to the literary means and, in general, the performative level of Bataille s texts. The study constructs three theoretical contexts for Bataille s question of religion first of all, the interpretation of Hegel in the mid-20th century French philosophy. In the first section of the study, Bataille s uneasy relationship with Hegel as mediated by Alexandre Kojève is explored. The motivation of his question of radical otherness is argued to arise from his struggle with the Hegelian Kojèvean notion of negativity. The second context is the dialogue with the Christian mystical tradition. Starting from the analysis of two Bataillean notions, dramatization and contestation , it is argued that, firstly, Bataille s approach to radical otherness is analogous to certain procedures of mystical texts while, secondly, the function of otherness providing no firm foundation in Bataille s texts differs from its function in mystical texts. In the third section of the study, Bataille s quest for otherness is concretized by analyzing his views on otherness of other person, on violence, and on death themes that are brought together in Bataille s lasting interest in sacrifice. Bataille s understanding of sacrifice is proportioned to social scientific and philosophical discussions on sacrifice. It is argued that the commitment to the idea of sacrifice accounts for a partial failure in the Bataillean approach to otherness, the otherness of other person remaining its (at least half) blind spot. The study presents an overview of Bataille s thought on religion. It brings out Bataille s view of the paradoxical fundamental yet impossible role of otherness in the construction of human world, as well as his understanding of religious representations as both covering over and indicating this otherness. It describes Bataille s atheological mysticism as a peculiar modern form of religiosity, as an ambivalent mourning for and exaltation of fundamental loss.

"Radiodiskurssin kontekstualisointi prosodisin keinoin. Esimerkkinä viisi suurta ranskalaista 1900-luvun filosofia" Väitöskirja käsittelee puheen kontekstualisointia prosodisin keinoin. Toisin sanottuna työssä käsitellään sitä, miten puheen prosodiset piirteet (kuten sävelkulku, intensiteetti, tauot, kesto ja rytmi) ohjaavat puheen tulkintaa vanhastaan enemmän tutkittujen sana- ja lausemerkitysten ohella. Työssä keskitytään seitsemään prosodisesti merkittyyn kuvioon, jotka koostuvat yhden tai usean parametrin silmiinpistävistä muutoksista. Ilmiöitä käsitellään sekä niiden akustisten muotojen että tyypillisten esiintymisyhteyksien ja diskursiivisten tehtävien näkökulmasta. Aineisto koostuu radio-ohjelmista, joissa puhuu viisi suurta ranskalaista 1900-luvun filosofia: Gaston Bachelard, Albert Camus, Michel Foucault, Maurice Merleau-Ponty ja Jean-Paul Sartre. Ohjelmat on lähetetty eri radiokanavilla Ranskassa vuosina 1948–1973. Väitöskirjan tulokset osoittavat, että prosodisesti merkityt kuviot ovat moniulotteisia puheen ilmiöitä, joilla on keskeinen rooli sanotun kontekstualisoinnissa: ne voivat esimerkiksi nostaa tai laskea sanotun informaatioarvoa, ilmaista puhujan voimakasta tai heikkoa sitoutumista sanomaansa, ilmaista rakenteellisen kokonaisuuden jatkumista tai päättymistä, jne. Väitöskirja sisältää myös kontrastiivisia osia, joissa ilmiöitä verrataan erääseen klassisessa pianomusiikissa esiintyvään melodiseen kuvioon sekä erääseen suomen kielen prosodiseen ilmiöön. Tulokset viittaavat siihen, että tietynlaista melodista kuviota käytetään samankaltaisena jäsentämiskeinona sekä puheessa että klassisessa musiikissa. Lisäksi tulokset antavat viitteitä siitä, että tiettyjä melodisia muotoja käytetään samankaltaisten implikaatioiden luomiseen kahdessa niinkin erilaisessa kielessä kuin suomessa ja ranskassa. Yksi väitöskirjan osa käsittelee pisteen ja pilkun prosodista merkitsemistä puheessa. Tulosten mukaan pisteellä ja pilkulla on kummallakin oma suullinen prototyyppinsä: piste merkitään tyypillisesti sävelkulun laskulla ja tauolla, ja pilkku puolestaan sävelkulun nousulla ja tauolla. Merkittävimmät tulokset koskevat kuitenkin tapauksia, joissa välimerkki tulkitaan prosodisesti epätyypillisellä tavalla: sekä pisteellä että pilkulla vaikuttaisi olevan useita eri suullisia vastaavuuksia, ja välimerkkien tehtävät voivat muotoutua hyvin erilaisiksi niiden prosodisesta tulkinnasta riippuen.

We investigate the extent and nature of use of use of twitter for financial reporting by ASX listed companies. We consider 199 financial information related tweets from 14 ASX listed companies’ Twitter accounts. A thematic analysis of these tweets shows ‘Earnings’ and ‘Operational Performance’ are the most discussed financial reporting themes. Further, a comparison across industry sectors reveals that listed companies from varies industries show different usage patterns of financial reporting on Twitter. The examination of tweet sentiments also indicates a reporting bias within these tweets, as listed companies are more willing to disclose positive financial reporting tweets.

Women and women s words in discussions about the ordination of women in the General Synod between 1974 and 1987. In 1986, the General Synod of the Evangelical Lutheran Church in Finland approved the ordination of women. Prior to that decision, a considerable amount of discussion and debate took place about this renewal in both the Synod and the general public. The different points of view had divided the church and the people, and had placed the church under pressure to resolve the issue as soon as possible. At the same time, the changing climate in people s attitudes toward the church and the changing position of women in society clearly weighed in on this matter. The research material consists of the speeches about the ordination of women given by the women representatives in the General Synod of the Evangelical Lutheran Church in Finland between the years 1974 and 1987. The aim is to determine why these representatives wanted to ordain women as pastors, what kind of women pastors they wanted to have in the congregations, and what they wanted to change in the church through this renewal. The basic methods of the analysis include discourse analysis as well as the new rhetorics and some concepts used by Pierre Bourdieu. A framework, which I named rhetoric patterning, was developed to interpret the results. This framework has facilitated the identification of three effective discourses in the studied argumentation: the folk church discourse, the pastor image discourse and the church image discourse. According to the opinions of the women representatives, the concept of change turned out to be a very decisive factor as the church sought a way to reach its members. To maintain a good and modern image seemed very important for the church to be able to perform its task in the modern era. The women representatives presented the situation of the church in terms of contextual theology and took seriously the membership of all those baptized into the church. They were therefore ready to take into account the opinion of all church members. The problem was that even though the ordination of women was established, the fixed mental schemes of the people and the strong power structures of the church remained untouched. Women were allowed into a new area of church life, but with certain publicly pronounced and unconsciously recognized conditions. Did this change really mean greater equality between women and men, as was intended? Key words: ordination of women, General Synod, contextualization, discourse analysis.
Developing standardized methods to assess cost of healthy and unhealthy (current) diets in Australia

Unhealthy diets contribute at least 14% to Australia's disease burden and are driven by ‘obesogenic’ food environments. Compliance with dietary recommendations is particularly poor amongst disadvantaged populations including low socioeconomic groups, those living in rural/remote areas and Aboriginal and Torres Strait Islanders. The perception that healthy foods are expensive is a key barrier to healthy choices and a major determinant of diet-related health inequities. Available state/regional/local data (limited and non-comparable) suggests that, despite basic healthy foods not incurring GST, the cost of healthy food is higher and has increased more rapidly than unhealthy food over the last 15 years in Australia. However, there were no nationally standardised tools or protocols to benchmark, compare or monitor food prices and affordability in Australia. Globally, we are leading work to develop and test approaches to assess the price differential of healthy and less-healthy (current) diets under the food price module of the International Network for Food and Obesity/non-communicable diseases (NCDs) Research, Monitoring and Action Support (INFORMAS). This presentation describes contextualization of the INFORMAS approach to develop standardised Australian tools, survey protocols and data collection and analysis systems. The ‘healthy diet basket’ was based on the Australian Foundation Diet, 1 The ‘current diet basket’ and specific items included in each basket, were based on recent national dietary survey data.2 Data collection methods were piloted. The final tools and protocols were then applied to measure the price and affordability of healthy and less healthy (current) diets of different household groups in diverse communities across the nation. We have compared results for different geographical locations/population subgroups in Australia and assessed these against international INFORMAS benchmarks. The results inform the development of policy and practice, including those relevant to mooted changes to the GST base, to promote nutrition and healthy weight and prevent chronic disease in Australia.

This paper provides a framework for understanding Twitter as a historical source. We address digital humanities scholars to enable the transfer of concepts from traditional source criticism to new media formats, and to encourage the preservation of Twitter as a cultural artifact. Twitter has established itself as a key social media platform which plays an important role in public, real-time conversation. Twitter is also unique as its content is being archived by a public institution (the Library of Congress). In this paper we will show that we still have to assume that much of the contextual information beyond the pure tweet texts is already lost, and propose additional objectives for preservation.

Enchanted by Sources. Henry Biaudet, Liisi Karttunen and Finnish Historical Research in Rome in the Early Twentieth Century This study traces the scholarly endeavours of Henry Biaudet (1870 1915) and Liisi Karttunen (1880 1957) and "La mission historique finlandaise à Rome" which they founded in 1909. They are forgotten in Finnish historiography, but remain internationally renowned for their contribution to the nunciature studies. By investigating their historical work on the Counter- Reformation era, their roles in the scientific communities of Helsinki and Rome as well as the intersection of politics and science in their scholarly practices the study explores the nature of historical research in general at the turn of the twentieth century. The work covers fields such as historiography, university history and the political use of history. Methodologically the research is based on the analysis and contextualization of published and unpublished sources (e.g. correspondences, university records, scholarly publications and reviews in academic journals). Henry Biaudet criticized the previous research on the Nordic Counter-Reformation for its narrow national scope and sources. He sought out a new approach, including the use of sources in archives all over Europe and the inclusion of the Catholic viewpoint. Accordingly, Biaudet and Karttunen searched for records in archives in Southern Europe. Their unorthodox interpretations were denounced in Finland since the picture they gave of late sixteenth-century Sweden was too different from the national narrative. Moreover, Finnish national identity was firmly rooted in Protestantism, and questioning the benevolence of the Reformation and its main actors was considered as an attack not only against historical truth but also national values. The comparison between Biaudet s and Karttunen s arguments and the accepted narrative in Finland shows how traditional interpretations of the Nordic Reformation were influenced by the Lutheran ethos and European anticlerical rhetoric. Historians have recently paid substantial attention to the political use of history, usually focusing on politicized constructions of the national past. This study shows how research that met the criteria of modern historiography also served political purposes. Conducting research in an international community of historians and publishing ambitious scholarly studies that interested an international audience were ways to create a positive image of Finland abroad. These were not uniquely Finnish ideas but rather ideas shared by the international community of historians in Rome. In this context, scientific pursuits were given a clear political meaning. This enhances our understanding of nineteenth-century historiography being firmly rooted between science and politics.

This dissertation traces a set of historical transformations the Darwinian evolutionary narrative has undergone toward the end of the twentieth century, especially as reflected in Anglo-American popular science books and novels. The study has three objectives. First, it seeks to understand the organizing logic of evolutionary narratives and the role that assumptions about gender and sexuality play in that logic. Second, it asks what kinds of cultural anxieties evolutionary theory raises and how evolutionary narratives negotiate them. Third, it examines the possibilities and limits of narrative transformation both as a historical phenomenon and as a theoretical question. This interdisciplinary dissertation is situated at the intersection of science studies, cultural studies, literary studies, and gender studies. Its understanding of science as a cultural practice that both emerges from and contributes to cultural expectations and institutional structures follows the tradition of science studies. Its focus on the question of popular appeal and the mechanisms of cultural change arises from cultural studies. Its view of narrative as a structural phenomenon is grounded in literary studies in general and feminist narrative theory in particular. Its understanding of gender and sexuality as implicated in discourses of epistemic authority builds on the view of gender and sexuality as contingent cultural categories central to gender studies. The primary material consists of over 25 British and American popular science books and novels, published roughly between 1990 and 2005. In order to highlight historical transformations, these texts are read in the context of Darwin s The Origin of Species and The Descent of Man, on the one hand, and such sociobiological classics as E. O. Wilson s On Human Nature and Richard Dawkins s The Selfish Gene, on the other. The research method combines feminist narrative analysis with cultural and historical contextualization, emphasizing discursive abruptions, recurrent narrative patterns, and underlying continuities. The dissertation demonstrates that the relationship between Darwin s evolutionary narrative and late twentieth-century evolutionary narratives is characterized by reemphasis, omissions, and continuous rewriting. In particular, contemporary evolutionary discourse extends the role assigned to reproduction both sexual and narrative in Darwin s writing, generating a narrative logic that imagines the desire to reproduce as the driving force of evolution and posits the reproductive sex act as the endlessly repeated narrative event that keeps the story going. The study argues that the popular appeal of evolutionary accounts of gender, sexuality, and human nature may arise, to an extent, from this reproductive narrative dynamic. This narrative dynamic, however, is not logically invulnerable. Since the continuation of the evolutionary narrative relies on successful reproduction, the possibility of reproductive failure poses a constant risk to narrative futurity, arousing cultural anxieties that evolutionary narratives need to address. The study argues that evolutionary narratives appease such anxieties by evoking a range of cultural narratives, especially romantic, religious, and national narratives. Furthermore, the study shows that the event-based logic of evolutionary narratives privileges observable acts over emotions, pleasures, identities, and desires, thus engendering a set of conceptual exclusions that limits the imaginative scope of evolution as a cultural narrative.

The problem of identifying user intent has received considerable attention in recent years, particularly in the context of improving the search experience via query contextualization. Intent can be characterized by multiple dimensions, which are often not observed from query words alone. Accurate identification of Intent from query words remains a challenging problem primarily because it is extremely difficult to discover these dimensions. The problem is often significantly compounded due to lack of representative training sample. We present a generic, extensible framework for learning the multi-dimensional representation of user intent from the query words. The approach models the latent relationships between facets using tree structured distribution which leads to an efficient and convergent algorithm, FastQ, for identifying the multi-faceted intent of users based on just the query words. We also incorporated WordNet to extend the system capabilities to queries which contain words that do not appear in the training data. Empirical results show that FastQ yields accurate identification of intent when compared to a gold standard.
