Open education materials related to the author's HCI textbook were released in 2013 as a MOOC, published on interactiondesign.org, and used for flipped classroom teaching. Work is in progress to link these free open educational resources including substantial video and quizzes (some tutor-only) together with the (paid-for but open-to-all) book, to create a 'semantic textbook'. The author is als...

Although thousands of students enroll in Massive Open Online Courses (MOOCs) for learning and self-improvement, many get confused, harming learning and increasing dropout rates. In this paper, we quantify these effects in two large MOOCs. We first describe how we automatically estimate students’ confusion by looking at their clicking behavior on course content and participation in the course di...

The huge amount of gathered data in a MOOC allows providing professors and course managers with insightful information about real course usage and consumption. The main aim of this work is to explore how efficient the video viewing is for completing and passing the first course offered by UCATx.cat platform, “Decoding Algebra”, in order to improve its design and resources. The statistical metho...

aneurysms of gastric vessels (dieulafoy`s disease, caliber-persistent artery) are thought to be of malformative rather than degenerative origin. they are usually single, located in the submucosa, usually on the lesser curvature, and characterized by a large tortuous vessel surmounted by a small defect in the overlying mucosa. when the lesion perforates, massive and sometimes fatal hemorrhage ma...

Massive bleeding in trauma patients is a serious challenge for all clinicians, and an interdisciplinary diagnostic and therapeutic approach is warranted within a limited time frame. Massive transfusion usually is defined as the transfusion of more than 10 units of packed red blood cells (RBCs) within 24 h or a corresponding blood loss of more than 1- to 1.5-fold of the body's entire blood volum...

  Abstract   A32 year-old multigravid patient with 10 weeks of pregnancy was referred to the emergency ward with massive vaginal bleeding and preshock state. Suction curettage, laparotomy, uterine artery ligation, Macdonald cerclage, and hysterectomy was done, in that order. After hysterectomy and massive transfusion she recovered. When a diagnosis of cesarean scar pregnancy is made in the emer...
