What people study when they study Tumblr:Classifying Tumblr-related academic research

Purpose: Since its launch in 2007, research has been carried out on the popular social networking website Tumblr. This paper identifies published Tumblr based research, classifies it to understand approaches and methods, and provides methodological recommendations for others. / Design/methodology/approach: Research regarding Tumblr was identified. Following a review of the literature, a classification scheme was adapted and applied, to understand research focus. Papers were quantitatively classified using open coded content analysis of method, subject, approach, and topic. / Findings: The majority of published work relating to Tumblr concentrates on conceptual issues, followed by aspects of the messages sent. This has evolved over time. Perceived benefits are the platform’s long-form text posts, ability to track tags, and the multimodal nature of the platform. Severe research limitations are caused by the lack of demographic, geo-spatial, and temporal metadata attached to individual posts, the limited API, restricted access to data, and the large amounts of ephemeral posts on the site. / Research limitations/implications: This study focuses on Tumblr: the applicability of the approach to other media is not considered. We focus on published research and conference papers: there will be book content which was not found using our method. Tumblr as a platform has falling user numbers which may be of concern to researchers. / Practical implications: We identify practical barriers to research on the Tumblr platform including lack of metadata and access to big data, explaining why Tumblr is not as popular as Twitter in academic studies. - Social implications This paper highlights the breadth of topics covered by social media researchers, which allows us to understand popular online platforms. / Originality/value: There has not yet been an overarching study to look at the methods and purpose of those who study Tumblr. We identify Tumblr related research papers from the first appearing in July 2011 until July 2015. Our classification derived here provides a framework that can be used to analyse social media research, and in which to position Tumblr related work, with recommendations on benefits and limitations of the platform for researchers

Advanced Signal Processing in Wearable Sensors for Health Monitoring

Smart, wearables devices on a miniature scale are becoming increasingly widely available, typically in the form of smart watches and other connected devices. Consequently, devices to assist in measurements such as electroencephalography (EEG), electrocardiogram (ECG), electromyography (EMG), blood pressure (BP), photoplethysmography (PPG), heart rhythm, respiration rate, apnoea, and motion detection are becoming more available, and play a significant role in healthcare monitoring. The industry is placing great emphasis on making these devices and technologies available on smart devices such as phones and watches. Such measurements are clinically and scientifically useful for real-time monitoring, long-term care, and diagnosis and therapeutic techniques. However, a pertaining issue is that recorded data are usually noisy, contain many artefacts, and are affected by external factors such as movements and physical conditions. In order to obtain accurate and meaningful indicators, the signal has to be processed and conditioned such that the measurements are accurate and free from noise and disturbances. In this context, many researchers have utilized recent technological advances in wearable sensors and signal processing to develop smart and accurate wearable devices for clinical applications. The processing and analysis of physiological signals is a key issue for these smart wearable devices. Consequently, ongoing work in this field of study includes research on filtration, quality checking, signal transformation and decomposition, feature extraction and, most recently, machine learning-based methods

The relationships between brand attributes and word of mouth on brand identity and brand image

Companies all around the world have to deal with issues relating to brand image development and maintenance because brand image can affect their brand performance. Based on the attribution theory, this research examined the impact of the components of brand attributes, namely brand relevance, brand consistency, brand sustainability, brand credibility, brand uniqueness and word of mouth (WOM) of brand image. This study also evaluated the mediating influence of brand WOM identity on the relationship between the brand attribute components, WOM and brand image. Insufficient empirical attention, particularly in relation to the attribution theory, was the driving force for the current study to be undertaken. Two hundred and fifty-four travellers via two airports located in the northern region of Malaysia participated in this study. A cross-sectional survey approach and the quota sampling technique were adopted to select the participants, and PLS algorithm and bootstrapping techniques were deployed to test the hypothesized relationships. The PLS path modelling reported significant results of the major hypotheses; brand sustainability was the only variable not significantly related to brand image. It was found that brand identity mediated significantly the relationship between brand attributes, WOM and brand image. Overall, the results provide support for the attribution theory in that brand attributes, namely brand relevance, brand consistency, brand sustainability, brand credibility, brand uniqueness and word of mouth can help shape consumers' perceptions which ultimately result in harnessing brand image. Finally, the study's implications for theory and practice, limitations, conclusions as well as directions for future research are provided and discussed

An awareness based approach to avoid rebound effects in ICTs

ABSTRACT The full exploitation of ICTs environmental potential benefits needs to take into account a social dimension, where there is a shift of role from passive user to aware user of ICT-based services. After a short overview of the rebound effect in ICTs, the paper will focus on the role that users, consumers or citizens can play in spreading and adopting beneficial behavior. The enabling factor of this active participative role is the collective situational awareness about environmental effects of actions. Such awareness makes a green behavior easier and can counter possible rebound effects. An Agent Based Model approach is proposed to study individual and collective behavioral changes toward sustainability using ICT-based services and for sustainable ICTs. The use of ABM to simulate how environmental awareness spread is innovative and crosses the disciplinary borders between ICTs, energy and environment disciplines, as well as social and behavioral sciences

The Extent and Coverage of Current Knowledge of Connected Health: Systematic Mapping Study

Background: This paper examines the development of the Connected Health research landscape with a view on providing a historical perspective on existing Connected Health research. Connected Health has become a rapidly growing research field as our healthcare system is facing pressured to become more proactive and patient centred. Objective: We aimed to identify the extent and coverage of the current body of knowledge in Connected Health. With this, we want to identify which topics have drawn the attention of Connected health researchers, and if there are gaps or interdisciplinary opportunities for further research. Methods: We used a systematic mapping study that combines scientific contributions from research on medicine, business, computer science and engineering. We analyse the papers with seven classification criteria, publication source, publication year, research types, empirical types, contribution types research topic and the condition studied in the paper. Results: Altogether, our search resulted in 208 papers which were analysed by a multidisciplinary group of researchers. Our results indicate a slow start for Connected Health research but a more recent steady upswing since 2013. The majority of papers proposed healthcare solutions (37%) or evaluated Connected Health approaches (23%). Case studies (28%) and experiments (26%) were the most popular forms of scientific validation employed. Diabetes, cancer, multiple sclerosis, and heart conditions are among the most prevalent conditions studied. Conclusions: We conclude that Connected Health research seems to be an established field of research, which has been growing strongly during the last five years. There seems to be more focus on technology driven research with a strong contribution from medicine, but business aspects of Connected health are not as much studied

The Internet and the Nigerian Woman: A Case of Female Undergraduates

The Internet has drastically changed information and knowledge sharing processes globally. It is a widely accepted medium for transformation and empowerment. Individuals, groups, communities and nations, including women in their quest for a gender sensitive society have adopted the Internet as a viable tool. However, despite the countless benefits of this important tool of communication, research, entertainment, publishing, and business, there are challenges that affect Internet access and use among female students at the University of Maiduguri, Nigeria. This paper examines Internet access and use among female undergraduates at a Nigerian University. Selected female undergraduates completed questionnaires. The findings shows that the university computer centre (University Cyber Café) is the major Internet access point among the respondents. Research (information searches and learning) ranked first in the uses of the Internet among respondents, with financial constraints as the major challenge to access and use of the Internet. Respondents found women-related websites useful. They derive a certain gratification from these sites. However, most respondents do not post or contribute material or information on the web. Their interaction with the web involves mostly downloading. The study concludes that Internet access and use status among female students at the University of Maiduguri and women in general would be greatly enhanced if women organizations concentrated on addressing the challenges identified in this study. Attention should be paid to this category of women (university students) who have the educational capabilities and Internet potential to impact women empowerment efforts
