Communicating health decisions: an analysis of messages posted to online prostate cancer forums

Background  Experiential websites such as message forums and blogs allow Prostate Cancer (PCa) patients to communicate their health decisions to peers. The issues surrounding this form of indirect involvement in public health are little understood. Objective  This paper explores the types of decision-making processes that people are exposed to on PCa online message boards. The kinds of treatment choices patients are making and the reports of their decision-making processes to peers through an online environment are examined in the context of the Heuristic Systematic Model. Method  Messages about treatment decision making were collected from four PCa websites. In total, 137 messages were selected from blogs and online forums and their decision-making processes coded. Results  Men looking online for information about treatment options for PCa are exposed to a range of decision-making processes. Just under half (49.6%) of the messages reported non-systematic decision processes, with deferral to the doctor and proof of cancer removal being the most common. For systematic processing (36.5%), messages most commonly considered treatment outcomes and side-effects. Processes did not vary between the blogs and online forums. Discussion and conclusion  Compared to previous studies far fewer messages reported non-systematic decision processes and only a small number of messages reflected lay beliefs or misbeliefs about PCa treatment. Implications for men and their clinicians of seeking health information online are discussed

Research Directions, Challenges and Issues in Opinion Mining

Rapid growth of Internet and availability of user reviews on the web for any product has provided a need for an effective system to analyze the web reviews. Such reviews are useful to some extent, promising both the customers and product manufacturers. For any popular product, the number of reviews can be in hundreds or even thousands. This creates difficulty for a customer to analyze them and make important decisions on whether to purchase the product or to not. Mining such product reviews or opinions is termed as opinion mining which is broadly classified into two main categories namely facts and opinions. Though there are several approaches for opinion mining, there remains a challenge to decide on the recommendation provided by the system. In this paper, we analyze the basics of opinion mining, challenges, pros & cons of past opinion mining systems and provide some directions for the future research work, focusing on the challenges and issues

Enhancing Moodle to meet the needs of 200,000 distance learners

In 2005 The Open University UK selected Moodle as the basis of its institutional virtual learning environment. Since then, the system has been integrated with existing elearning and administrative systems at the University and considerably enhanced during an extensive development programme costing around €8m and taking nearly three years. Many policy issues have emerged which needed to be tackled alongside the software developments in order for the platform to be adopted by the 7,000 tutors and nearly 200,000 students of the University. The Moodle system has proven to be reliable, scalable and customisable and has resulted in a more flexible system for the Open University than the commercial alternatives. This paper examines some of the many enhancements made to Moodle by the Open University, most of which have been fed back into the product for the benefit of other Moodle users. It describes some of the policy and pedagogical issues which have emerged during the roll-out of Moodle across the University

Social media as a data gathering tool for international business qualitative research: opportunities and challenges

Lusophone African (LA) multinational enterprises (MNEs) are becoming a significant pan-African and global economic force regarding their international presence and influence. However, given the extreme poverty and lack of development in their home markets, many LA enterprises seeking to internationalize lack resources and legitimacy in international markets. Compared to higher income emerging markets, Lusophone enterprises in Africa face more significant challenges in their internationalization efforts. Concomitantly, conducting significant international business (IB) research in these markets to understand these MNEs internationalization strategies can be a very daunting task. The fast-growing rise of social media on the Internet, however, provides an opportunity for IB researchers to examine new phenomena in these markets in innovative ways. Unfortunately, for various reasons, qualitative researchers in IB have not fully embraced this opportunity. This article studies the use of social media in qualitative research in the field of IB. It offers an illustrative case based on qualitative research on internationalization modes of LAMNEs conducted by the authors in Angola and Mozambique using social media to identify and qualify the population sample, as well as interact with subjects and collect data. It discusses some of the challenges of using social media in those regions of Africa and suggests how scholars can design their studies to capitalize on social media and corresponding data as a tool for qualitative research. This article underscores the potential opportunities and challenges inherent in the use of social media in IB-oriented qualitative research, providing recommendations on how qualitative IB researchers can design their studies to capitalize on data generated by social media.https://doi.org/10.1080/15475778.2019.1634406https://doi.org/10.1080/15475778.2019.1634406https://doi.org/10.1080/15475778.2019.1634406https://doi.org/10.1080/15475778.2019.1634406Accepted manuscriptPublished versio

Routinisation of Audience Participation: BBC News Online, Citizenship and Democratic Debate

Leading up to the 2010 UK general election, Director General of the BBC, Mark Thompson, stressed the importance of the Corporation’s ability ‘to provide a strong and independent space where the big debates can take place, free from political or commercial influence’. ‘In this public space,’ he continued, ‘everyone can have access to the lifeblood of healthy democratic debate – impartial news and information’. Affirming the importance of BBC Online, Thompson described it as ‘being a cornerstone of what the BBC should be about’ (Thompson, 2010). As with previous elections, one of the key strategic priorities for the BBC’s Election 2010 website was to help inform the citizenry about the campaign and empower voters to make an informed choice. In the most traditional sense, this was achieved through the BBC’s journalism and a series of rich background features – e.g. guidance on voting procedures, MPs and parliamentary politics, and comparisons of party manifestos. The BBC election websites have also featured experimentation with various forms of audience engagement, exemplified by different interactive features on the BBC micro websites for the 1997, 2001, 2005 and 2010 UK general elections. This has traditionally been anchored in the Corporation’s public service commitment to facilitating ‘civic engagement’ and providing ‘democratic value’ to British citizens (see also Thorsen et al., 2009, Thorsen, 2010, 2011, Allan and Thorsen, 2010). The BBC’s news website was incredibly popular during the 2010 election according to visitor statistics. On results day, May 7, BBC News Online had 11.4 million individual users, breaking the previous record set on November 5, 2008, for the election of Barack Obama as US President (Herrmann, 2010). Comparing this to 2005, the number of unique visitors to the BBC’s election site on results day, May 6, was 3 million taking the overall BBC News Online total to 4.3 million (Ward, 2006:17). This demonstrates a near three-fold increase in individual users from one election to the next and indicates that whilst the internet might not be perceived as having had a significant impact on the election outcomes, the BBC has certainly had a considerable impact on citizens’ online activities. Based on a larger study into BBC’s election websites involving interviews, observations and textual analysis, this chapter will examine how audience participation had by 2010 become a routinised part of the Corporation’s newsroom. It will begin by providing an historical overview of how public access programming has developed within the BBC and its influence on how the Corporation has sought to facilitate participatory spaces online. Following a discussion of online participatory spaces on the BBC’s election websites, it will offer a critique of how these are operationalized internally. It will argue that despite converged newsroom practices, the scale of the BBC’s operations means facilitation of civic engagement is fragmented between competing stakeholders within the Corporation each with their own routinised practices and perception of its value. This tension has a dramatic effect not only on the dialectic relationship between BBC journalists and its audiences, but also on the type of ‘public space’ the Corporation is able to foster and by extension the empowerment of citizens to engage in ‘healthy democratic debate’

Mining online diaries for blogger identification

In this paper, we present an investigation of authorship identification on personal blogs or diaries, which are different from other types of text such as essays, emails, or articles based on the text properties. The investigation utilizes couple of intuitive feature sets and studies various parameters that affect the identification performance. Many studies manipulated the problem of authorship identification in manually collected corpora, but only few utilized real data from existing blogs. The complexity of the language model in personal blogs is motivating to identify the correspondent author. The main contribution of this work is at least three folds. Firstly, we utilize the LIWC and MRC feature sets together, which have been developed with Psychology background, for the first time for authorship identification on personal blogs. Secondly, we analyze the effect of various parameters, and feature sets, on the identification performance. This includes the number of authors in the data corpus, the post size or the word count, and the number of posts for each author. Finally, we study applying authorship identification over a limited set of users that have a common personality attributes. This analysis is motivated by the lack of standard or solid recommendations in literature for such task, especially in the domain of personal blogs. The results and evaluation show that the utilized features are compact while their performance is highly comparable with other larger feature sets. The analysis also confirmed the most effective parameters, their ranges in the data corpus, and the usefulness of the common users classifier in improving the performance, for the author identification task

Events and Controversies: Influences of a Shocking News Event on Information Seeking

It has been suggested that online search and retrieval contributes to the intellectual isolation of users within their preexisting ideologies, where people's prior views are strengthened and alternative viewpoints are infrequently encountered. This so-called "filter bubble" phenomenon has been called out as especially detrimental when it comes to dialog among people on controversial, emotionally charged topics, such as the labeling of genetically modified food, the right to bear arms, the death penalty, and online privacy. We seek to identify and study information-seeking behavior and access to alternative versus reinforcing viewpoints following shocking, emotional, and large-scale news events. We choose for a case study to analyze search and browsing on gun control/rights, a strongly polarizing topic for both citizens and leaders of the United States. We study the period of time preceding and following a mass shooting to understand how its occurrence, follow-on discussions, and debate may have been linked to changes in the patterns of searching and browsing. We employ information-theoretic measures to quantify the diversity of Web domains of interest to users and understand the browsing patterns of users. We use these measures to characterize the influence of news events on these web search and browsing patterns

Social Media and the Public Sector

{Excerpt} Social media is revolutionizing the way we live, learn, work, and play. Elements of the private sector have begun to thrive on opportunities to forge, build, and deepen relationships. Some are transforming their organizational structures and opening their corporate ecosystems in consequence. The public sector is a relative newcomer. It too can drive stakeholder involvement and satisfaction. Global conversations, especially among Generation Y, were born circa 2004. Beginning 1995 until then, the internet had hosted static, one-way websites. These were places to visit passively, retrieve information from, and perhaps post comments about by electronic mail. Sixteen years later, Web 2.0 enables many-to-many connections in numerous domains of interest and practice, powered by the increasing use of blogs, image and video sharing, mashups, podcasts, ratings, Really Simple Syndication, social bookmarking, tweets, widgets, and wikis, among others. Today, people expect the internet to be user-centric

Needs and challenges for online language teachers - the ECML project DOTS

The growing use of digital technologies in educational settings, paralleled by a paradigm change in educational theory from an instructivist transmission approach to constructivist and sociocultural theories of learning, demands more adapted teacher training programs, both technical and pedagogical. Looking at factors influencing teachers’ implementation of ICT in the foreign language classroom and guided by the results of a needs analysis survey conducted among twenty six language teachers from twenty five different European countries, the DOTS project aims to develop an online workspace with bite-sized learning objects for autonomous use by language professionals, particularly freelance teachers who frequently miss out on the training opportunities provided for their full-time colleagues
