Qualitative data analysis

Qualitative data analysis, used by researchers to make sense of their data, comes in a variety of approaches which tend to be aligned with particular conceptual frameworks and methods. This chapter focusses on three approaches: thematic analysis and category coding, qualitative content analysis, and discourse analysis. With thematic analysis and category coding, which can be considered a foundational inductive approach, the researcher looks for connections within data, often collected in the field, and identifies thematic patterns. The approach is demonstrated with suggested steps that a researcher might follow. The emergence of qualitative content analysis from quantitative content analysis introduces the second approach, which focusses on a wide range of media, is inductive and deductive, highly systematic, and starts with an initial framework. Steps for undertaking this type of analysis are also included. The last approach, discourse analysis, is also used for a wide range of media. Its focus is on explori…

Acute and residual effects of stepwise increasing therapeutic doses of ketamine on neurocognitive and neurobehavioural performance in healthy adults

Background/Objective: Ketamine elicits dose-dependent changes in several cognitive domains; however, the impact of this drug on functional neurocognitive outcomes under acute therapeutic doses is equivocal. This study aimed to examine the acute and residual effects of three, stepwise increasing therapeutic-range doses of intravenously administered ketamine solution applied neurocognitive and behavioural functions in healthy adults. This study incorporated aspects of lower and higher-order cognitive and neurobehavioral domains assessed at each treatment step and at 2-hours post infusion in order to identify specific acute and residual deficits ability and behaviour. Methods: In an open-label, within-subjects study, three stepwise increasing therapeutic doses of intravenous (IV) ketamine infusions comprising (i) 8 mg/hour IV infusion plus initial (one-off) 30 mg bolus of ketamine, (ii) 12 mg/hour IV infusion and (iii) 20 mg/hour infusion were administered to 20 participants no know allergies to anaesthe…

Pigeon-Table: A quick prototyping tool using Twitter Bootstraps and AngularJS for data-driven web application development

Data-driven web applications are now taking over the role of traditional desktop applications as it is more convenient to the end user. However, developing a web application is considered challenging especially for junior web developers due to development processes, e.g. selection of development frameworks, learning the framework with lengthy documentations as well as experiment, or integrating the framework during the development. In this paper we proposed and developed a quick prototyping tool, "pigeon-table", for datadriven web application development specifically focusing on data retrieval from MySQL database and render the data into an interactive table in a web application. The aims of this project are, 1) to optimize web developers' productivity in web application development as the tool is straightforward and simple, and 2) to enhance end user browsing experience with an interactive table in the data-driven web application.

Impact of financial ratios and technical analysis on stock price prediction using random forests

A stock movement prediction method is presented using quarterly financial ratio data from Hong Kong companies from the period, 2011-2014. We found that the accuracy of price movement prediction using Random Forest method over multiple quarters to be fairly weak. However we were able to predict with high accuracy in the last quarter of 2014 and not in other years. We attribute this not to the superiority of the method but to the non-stationary nature of the price signals.

Arduino-based smart garbage monitoring system analysis requirement and implementation

With the growth of cities, the waste produced also increases. Many of the world's developing cities are still lacking in the area of waste management, in particular, the collection of garbage within the cities. Because of this, garbage tends to pile up in certain areas. This not only poses a health risk to the surrounding communities, but also creates unpleasant environments for the residents. To provide a solution to this problem, a smart garbage monitoring system is therefore proposed to tackle the issues faced. This system will allow the city authorities to better manage their resources in the collection of garbage and provide a platform that will allow for an efficient garbage collection system.

Revival of the Magnetar PSR J1622–4950: Observations with MeerKAT, Parkes, XMM-Newton, Swift, Chandra, and NuSTAR

New radio (MeerKAT and Parkes) and X-ray (XMM-Newton, Swift, Chandra, and NuSTAR) observations of PSR J1622-4950 indicate that the magnetar, in a quiescent state since at least early 2015, reactivated between 2017 March 19 and April 5. The radio flux density, while variable, is approximately 100x larger than during its dormant state. The X-ray flux one month after reactivation was at least 800x larger than during quiescence, and has been decaying exponentially on a 111 +/- 19 day timescale. This high-flux state, together with a radio-derived rotational ephemeris, enabled for the first time the detection of X-ray pulsations for this magnetar. At 5%, the 0.3-6 keV pulsed fraction is comparable to the smallest observed for magnetars. The overall pulsar geometry inferred from polarized radio emission appears to be broadly consistent with that determined 6-8 years earlier. However, rotating vector model fits suggest that we are now seeing radio emission from a different location in the magnetosphere than previousl…

Gastroenterologist performed point-of-care gastrointestinal ultrasound improves patient understanding of disease activity, symptomatology, management decisions and clinical outcomes

Background: There is limited utilisation of gastrointestinal ultrasonography (GIUS) in inflammatory bowel disease (IBD) by clinicians around the world. This study evaluated the benefits of IUS in IBD management from the patient’s perspective and the value of GIUS in clinical decision-making. Methods: This was an observational, non-interventional cohort study investigating the real-world clinical management of patients (≥18 years of age) diagnosed with IBD. During routine outpatient consultations, patients were allocated to receive GIUS or not according to their clinical requirements. Patients completed self-reported questionnaires at study entry, immediately after their consultation and then at 4 and 16 weeks post-consultation. Clinicians reported disease activity status, therapeutic decisions and clinical management. Results: Patients (GIUS: 70 of 259[27%]; non-GIUS: 189 of 259[73%]) were aged 39.7 ± 12.8 years, 139 of 259 (54%) were male and 159 of 259 (61%) were diagnosed with Crohn’s disease. Mean time si…

Demand response in presence of multiple suppliers

In demand side management electricity consumers are systematically encouraged by a load serving entity (LSE) to adjust their electricity demand to reduce overall costs. Li et al. [1] have presented such an iterative demand response program. In each iteration it sends price signals to the consumers against their demands for each hour of the day ahead, and smart consumer appliances adjust their usage accordingly to maximize their utility given the prices. The price signal is the marginal cost based on a single quadratic and piecewise smooth cost function. We extend previous work to allow multiple cost functions one for each supplier, and require that the LSE optimizes procurement jointly with the demand response. The price signal is then based on the optimal cost of procurement from all suppliers, computed using sequential quadratic programming (SQP). However, when the number of cost functions grows computing the price signal in each iteration becomes a bottleneck. Therefore, we also introduce an approximation …

Analysis of the textual content of mined open source usability defect reports

Writing a good usability defect report can be a tedious task, especially in identifying what important information should be included, and capturing the attention of software developers to fix them. This paper is a continuity of our previous studies investigating software development practitioners' day-to-day practices when dealing with usability defects. In this study, we mined 377 developer-tagged usability defect reports from Mozilla Thunderbird, Firefox for Android and Eclipse Platform to confirm what software development practitioners claimed to provide when reporting usability defects. We looked for the presence of key defect attributes steps to reproduce, impact, software context, expected output, actual output, assumed causes, solution proposal and supplementary information. In addition, we analyzed the trend of different types of usability defects, correlation between usability defects and defect severity, and failure qualifier. Our findings demonstrate a mismatch between what software development pr…
