Blended learning has received much interest in higher education as a way to increase efficiency and effectiveness. By combining face-to-face teaching with technology-enhanced through online resources, students can manage their own learning. methods are of particular professional degree programs such veterinary medicine which need the flexibility undertake intra- extramural activities develop ra...

Face recognition continues to meet significant challenges in reaching accurate results and still remains one of the activities where humans outperform technology. An attractive approach in improving face identification is provided by the fusion of multiple imaging sources such as visible and infrared images. Hyperspectral data, i.e. images collected over hundreds of narrow contiguous light spec...

The objective of this work is to provide an efficient face recognition scheme useful for video indexing applications. In particular we are addressing the following problem: given a set of known images and given a video sequence to be indexed, find where the corresponding persons appear in the sequence. Conventional face detection schemes are not well suited for this application and alternate an...

We use Goffman’s characterization of "front" and "backstage" interaction practices to analyze how the use of instant messaging in both face-to-face and technology-mediated meetings alters the spatial, temporal, and social configurations of meetings. In an interview study of workers in two organizations, we found that workers used instant messaging during face-to-face meetings and telephone co...

One way that firms have adapted to competitive pressures in today’s global marketplace is to use asynchronous communication technologies to support virtual project teams. To better understand the effectiveness of these dispersed teams, we compare the asynchronous communication transcripts of high and low performing virtual teams working on the early stages of software design. We also compare th...

Blended online learning is an emerging variation of blended learning. Whereas blended learning enhances face-to-face classroom instruction by adding asynchronous online instruction via a learning management system, blended online learning adds synchronous online learning via web conferencing to enhance otherwise asynchronous online courses. Blended online learning can potentially attract season...

Patients with more advanced glaucoma are likely to experience problems with everyday visual tasks such as face recognition. However, some patients still perform well at face recognition despite their visual field (VF) defects. This study investigated whether certain eye movement patterns are associated with better performance in the Cambridge Face Memory Test. For patients with bilateral VF def...

Face detection is fundamental for several important applications, such as, face recognition and human-computer interaction. This paper details a novel hierarchical face detector which combines motion, colour and late fusion. Motion segmentation is employed to eliminate background clutter and to reduce the initial search space. Subsequently, skin segmentation is used to determine a candidate fac...

Stable and clear visible facial features are crucial for the tasks in human face perception, such as face detection and tracking. Among other features, the center point between the eyes, or the “Between-the-Eyes” (BTE) has been found to be one of the good choices. In this paper, we propose a simple and fast way of extracting this facial feature from a facial image. By using down-sampling strate...

To date, few studies have examined the association between difficulties in activities of daily living (ADL) and suicidal ideation (SI) among the seniors in China. This study aims to explore this association among older adults in China. A total of 3313 older people (60+) were included in this study, and questionnaires were administered by face-to-face interview. In total, 4.2% of the participant...
