Query expansion is generally a useful technique in improving search performance. However, some expanded(More)
Over the past decades, usability techniques have been introduced into software development practices. At the same time many software development teams have started to use the agile development process – Scrum – to plan and organize their software projects. The focus of this study is to explore how usability techniques are integrated during software(More)
For information workers, maintaining high productivity relies on timely task resumption after interruptions, which are frequent. However, people's task resumption ability is compromised by disruptive environments and human cognitive limitations. We propose that a helpful intervention is to provide visual feedback about the duration of a suspended task.(More)
The article investigates the phonetic and phonological property of focal accents conveyed by disyllabic focused words with various tonal combinations in Standard Chinese. Phonetically, the effect of focal accents upon f 0 resides in two aspects: the manner and the condition of focal accents. Phonologically, the distribution of focal accents is mainly(More)
PICK1 is a PDZ/BAR domain-containing scaffold protein that regulates the trafficking of many receptors and ion channels, including AMPA receptors. In addition to binding to a wide spectrum of target proteins to be transported, the PICK1 PDZ domain, via its conserved CPC motif, has also been shown to bind to lipid membranes. However, the molecular basis of(More)
In today's "overloaded" information environment, deciding a stopping point for an exploratory search is not an easy decision. In this paper, we present the design and implementation of two search techniques: Result Preview (RP) and History Review (HR), to help people assess whether the information gained is enough and decide if he/she should quit or(More)
While motivational affordances are widely used to enhance user engagement in "gamified" apps, they are often employed en masse. Prior research offers little guidance about how individuals with different dispositions may react-positively and negatively-to specific affordances. In this paper, we present a survey study investigating the relationships among(More)
Calprotectin is a calcium-binding cytosolic protein, mainly expressed in immune cells, such as neutrophils, monocytes, and macrophages. Our study aimed to evaluate the diagnostic value of calprotectin for adult-onset Still's disease (AOSD), by comparing serum calprotectin concentrations in patients with AOSD (n = 46), rheumatoid arthritis (RA, n = 34),(More)
In our research group, we are currently carrying out several empirical research studies to inform the design of future personal informatics (PI) systems. These studies include projects investigating the use of gamification elements to encourage engagement based on a user's personality type, varying levels of feedback during day-to-day PI use, and(More)
