Any area of knowledge is structured by an intricate interplay of limits intrinsic to that area Limits have two opposite functions setting apart and joining An apparently restrictive limit may actually reveal itself as liberating We discuss the role that limits play in the real world in our mathematical idealizations and in the mappings between them We pro pose a classi cation of limits and sugg...
With the success of numerous applications of the Web 2.0 the interest in a web–based support of scientific communities has also gained significant relevance. The concept of Wikis, one building block of the Web 2.0, has shown to be a reasonable infrastructure for sharing and refining any kind of knowledge. The most prominent example is the encyclopedia Wikipedia, but many smaller wiki applicatio...
Event-related potentials (ERPs) are indicators of brain activity related to cognitive processes. They can be detected from EEG signals and thus constitute an attractive non-invasive option to study cognitive information processing. The P300 wave is probably the most celebrated example of an event-related potential and it is classically studied in connection to the odd-ball paradigm experimental...
This paper discovers patterns of knowledge dissemination among scientific disciplines. While the transfer of knowledge is largely unobservable, citations from one discipline to another have been proven to be an effective proxy to study disciplinary knowledge flow. This study constructs a knowledge flow network in that a node represents a Journal Citation Report subject category and a link denot...
Considering the importance of knowledge sharing as the most important factor in the science production process, this study investigated the relationship between these two variables from viewpoints of faculty members of Knowledge and Information Science at public universities in Tehran. This study was an applied and descriptive-correlation study. The statistical population consisted of 48 facul...
this thesis attempts to investigate the effects of prelistening activities on enhancing iranian efl learners` listening comprehension. the present study investigated ways in which learners` background knowledge could be activated in order to enhance their l2 listening comprehension by limiting the number of possible text interpretations prior to listening. the experiments conducted in this stud...
abstract the variables affecting the nature of reading comprehension can be classified into two general categories: reader’s variables, and text variables (alderson, 2000). despite the wave of research on vocabulary knowledge as reader’s variable, the role of this knowledge in c-test as a text-dependent test and its interaction with lexical cohesion of the test as a text feature has remained a...
Interdisciplinary studies of the sciences have been dramatically transformed over the past two decades by sociological studies of scientific knowledge. The postpositivist interdisciplinary formulation of "history and philosophy of science" has been fundamentally challenged by the sociological perspectives offered by the Edinburgh "Strong Programmed" the Bath constructivistrelativist approach, a...
This thesis is focused on building knowledge bases (KBs) for scientific domains. Specifically, we create structured representations of technical-domain information using unsupervised or semi supervised learning methods. This work is inspired by recent advances in knowledge base construction based on Web text. However, in the technical domains we consider here, we have grounded data about the ob...
