Massive Open Online Courses (MOOCs) have recently experienced rapid development and garnered significant attention from various populations. Despite the wide recognition of MOOCs as an important opportunity within educational practices, there are still many questions as to how we might satisfy students' needs, as evidenced by very high dropout rates. Researchers lack a solid understanding of what student needs are being addressed by MOOCs, and how well MOOCs now address (or fail to address) these needs. To help in building such an understanding, we conducted in-depth interviews probing student motivations, learning perceptions and experiences towards MOOCs, paying special attention to the MOOC affordances and experiences that might lead to high drop rates. Our study identified learning motivations, learning patterns, and a number of factors that appear to influence student retention. We proposed that the issue of retention should be addressed from two perspectives: retention as a problem but also retention as an opportunity.

The goal of the present study was to develop a cost-effective, man–machine digital interface, to improve students' real-world firing range training, results, and achievement scores. A serious game-based learning environment was developed, integrating invisible laser infrared technology, 1:1 real-scale rifle guns with recoil effects, as well as 3D interactive virtual reality (VR) military training digital information content, to train students in military live firing. To evaluate the effectiveness of the proposed design, students' performance, in terms of their learning achievement and learning motivation, was examined. One hundred and sixty high school students from Taiwan were divided into four individual groups of 40 students each, with one control group and three experimental groups (EG1, EG2, and EG3). The data were analyzed by one-way analysis of variance. The results of this cost-effective 3D VR showed significantly better learning motivation, learning outcomes, and positive impacts on users' actual live firing achievement scores.

Activated protein C (APC) has both anticoagulant activity and direct cell-signaling properties. APC has been reported to promote cancer cell migration/invasion and to inhibit apoptosis and therefore may exacerbate metastasis. Opposing these activities, APC signaling protects the vascular endothelial barrier through sphingosine-1-phosphate receptor-1 (S1P1)activation, which may counteract cancer cell extravasation. Here, we provide evidence that endogenous APC limits cancer cell extravasation, with in vivo use of monoclonal antibodies against APC. The protective effect of endogenous APC depends on its signaling properties. The MAPC1591 antibody that only blocks anticoagulant activity of APC does not affect cancer cell extravasation as opposed to MPC1609 that blocks anticoagulant and signaling properties of APC. Combined administration of anti-APC antibodies and S1P1 agonist (SEW2871) resulted in a similar number of pulmonary foci in mice in presence and absence of APC, indicating tha...

To study adherence to the widely accepted surveillance guidelines for patients with long-standing colitis in The Netherlands. A questionnaire was sent to all 244 gastroenterologists in The Netherlands. The response rate was 63%. Of all gastroenterologists, 95% performed endoscopic surveillance in ulcerative colitis (UC) patients and 65% in patients with Crohn's colitis. The American Gastroenterological Association (AGA) guidelines were followed by 27%, while 27% and 46% followed their local hospital protocol or no specific protocol, respectively. The surveillance was correctly initiated in cases of pancolitis by 53%, and in cases of left-sided colitis by 44% of the gastroenterologists. Although guidelines recommend 4 biopsies every 10 cm, less than 30 biopsies per colonoscopy were taken by 73% of the responders. Only 31%, 68% and 58% of the gastroenterologists referred patients for colectomy when low-grade dysplasia, high-grade dysplasia (HGD) or Dysplasia Associated Lesion or M...

Faces are an important visual category for many taxa, and the human face is no exception to this. Because faces differ in subtle ways and possess many idiosyncratic features, they provide a rich source of perceptual cues. A fair amount of those cues are learned through social interactions and are used for future identification of individual humans. These effects of individual experience can be studied particularly well in hetero-specific face perception. Domestic dogs represent a perfect model in this respect, due to their proved ability to extract important information from the human face in socio-communicative interactions. There is also suggestive evidence that dogs can identify their owner or other familiar human individuals by using visual information from the face. However, most studies have used only dogs' looking behavior to examine their visual processing of human faces and it has been demonstrated only that dogs can differentiate between familiar and unknown human faces. Here, we examined the dog's ability to discriminate the faces of two familiar persons by active choice (approach and touch). Furthermore, in successive stages of the experiment we investigated how well dogs discriminate humans in different representations by systematically reducing the informational richness and the quality of the stimuli. We found a huge inter-individual and inter-stage variance in performance, indicating differences across dogs in their learning ability as well as their selection of discriminative cues. On a group level, the performance of dogs significantly decreased when they were presented with pictures of human heads after having learned to discriminate the real heads, and when - after relearning - confronted with the same pictures showing only the inner parts of the heads. However, as two dogs quickly mastered all stages, we conclude that dogs are in principle able to discriminate people on the basis of visual information from their faces and by making active choices.

Abstract Killeen and Fetterman (1988) proposed a behavioral theory of timing (BeT) in which temporal discriminations are mediated by overt behaviors. Transitions between these mediating behaviors are instigated by pulses from an internal pacemaker, whose rate is proportional to the frequency of reinforcement in the experimental context. The current experiments are designed to determine how amount and probability of reinforcement affect the pacemaker's speed, and to clarify the context that forms the timebase for reinforcement ...

Conditioned pattern preferences were induced in 20 human participants using a computerized touch screen procedure. Three abstract monochrome patterns, presented incidentally to the subject over 180 trials in the context of a counting task, were randomly assigned to one of three reinforcement contingencies. One pattern was paired with positive visual and auditory feedback together with food reward on 90% of

We investigated whether search accuracy of adult humans could be enhanced using differential reward contingencies in landmark-based spatial tasks conducted on a computer screen. We found that search accuracy was significantly enhanced by differential outcomes in a conditional spatial search task, in which the landmark-to-goal relationship depended on a previously presented sample object (Experiment 4). In contrast, no significant differential outcomes effect (DOE) was seen in several other variations of spatial search tasks. We interpret the pattern of significant and non-significant results in terms of the information value of outcome expectancies. To our knowledge this is the first report of a DOE in a landmark-based spatial localization task and is one of only a few demonstrations that differential outcomes can enhance memory performance in normal functioning adults.
