This paper investigates how performance of students progresses during their studies. Progression of a student is defined as a tuple that shows how a year average stays the same, increases or decreases compared to first year. Taking the data of two consecutive cohorts and using k-means clustering, five meaningful types of progressions are put in evidence and intuitively visualized with a deviati...

Student modeling approaches predominantly focus on modeling student knowledge. For effective learning, however, it is necessary to teach students how to learn, as well as to provide support for learning domain knowledge. Recently, a number of projects focused on students’ learning strategies, and initiated work on modeling students’ metacognitive skills, such as self-explanation and reflection....

Although strategic alignment is an important theoretical concept, and achieving alignment or fit among organizational elements would seem to be an important business objective, empirical demonstrations of the importance of alignment have been uncommon (White 1986). This study attempted to provide an empirical assessment of the nature and importance of information systems strategic alignlnent Th...

Most studies on tilt based interaction can be classified as point-designs that demonstrate the utility of wrist-tilt as an input medium; tilt parameters are tailored to suit the specific interaction at hand. In this paper, we systematically analyze the design space of wrist-based interactions and focus on the level of control possible with the wrist. In a first study, we investigate the various...

When an infant or young child presents with subdural haemorrhage, the diagnostic priority is to exclude physical child abuse. A team approach should be adopted for the clinical child protection investigation. The diagnostic process is inevitably one of detective work; appropriate radiological, ophthalmological, haematological, biochemical, and postmortem investigations are discussed.

Cerebral oedema can be classified as the tangible swelling produced by expansion of the interstitial fluid volume. Hydrocephalus can be succinctly described as the abnormal accumulation of cerebrospinal fluid (CSF) within the brain which ultimately leads to oedema within specific sites of parenchymal tissue. Using hydrocephalus as a test bed, one is able to account for the necessary mechanisms ...

Gestalt psychologists proposed two distinct learning mechanisms. Associative learning occurs gradually through the repeated co-occurrence of external stimuli or memories. Insight learning occurs suddenly when people discover new relationships within their prior knowledge as a result of reasoning or problem solving processes that re-organize or restructure that knowledge. While there has been a ...

This paper presents an agent-based simulation tool that enables researchers to study entrepreneurial strategies, their associated financial payoffs, and their knowledge creation potentials under different environmental conditions. Opportunity recognition processes can be analyzed in detail both on a microand macro-level.

For more than eight years, Richard P. Brown, M.D., associate professor of clinical psychiatry at Columbia University College of Physicians and Surgeons, has used the natural dietary supplement S-adenosylmethionine (SAM-e) to treat more than an estimated 400 patients suffering from depression, many of whom were treatment-resistant. This month, Brown is scheduled to discuss SAM-e at the American ...
