"... In PAGE 9: ...Table 3: Social Presence Densities by Group (n=10) The social presence densities for the messages of the students in the high and low social presence groups are compared in Table3 . It shows that the messages of students perceiving the most presence of others in online discussion also contained far more social presence indicators, on average one and a half times more.... ..."

"... In PAGE 10: ... As the structural dimension merely orders the elements of the communication processes introduced in the context dimension, we do not give a more detailed treatment here. Instead, in Table1 , we give examples of context and structural elements in the different cells of the social context model. This is not an exhaustive list, but should be considered a good illustration of how the model can be used to organize the complexity of discussion processes in their context.... ..."

"... In PAGE 11: ...3. Social desirability, social presence and involvement In order to evaluate the quality of the data obtained we have measured social desirability bias using a four item scale taken from the German General Social Survey ( Table3 , top section). Only for one of the four items we observe a significant difference according to which the video mode seemed to yield more socially desirable answers.... ..."

"... In PAGE 13: ... Definitions of social presence While definitions of social presence vary, they cluster around key approaches or dimensions. See Table1 for outline of review of social presence definitions and theories presented below. Insert Table 1 here.... In PAGE 13: ... See Table 1 for outline of review of social presence definitions and theories presented below. Insert Table1 here. Non-definitional formulations of social presence Let us begin with examples of un-problematic or non-definitional ... In PAGE 40: ... 38 delimited set of phenomena for which we use the term, social presence, then we should be able to define the scope of phenomena that they seek to explain and criteria for assessing the value of a social presence theory and measure. In Table1 we examined definitions of social presence and organized them by the dimensions that appear to be underlying current conceptualization of social presence. Thus, one criterion for judging any theory and measure of social presence is the extent to which it differentiates among these various dimensions and makes explicit which are being included or excluded.... ..."

"... In PAGE 22: ... With the mature student, it has already occurred, and with the young student, it will occur at a later stage. The varieties of students, modes of instruction, and corresponding options for online delivery can be generalized as in Table5 . Of course the categories in this table are by no means definitive; they have been formulated only to help with ensuing discussion.... In PAGE 39: ... Similarly, archived material can be mined to assess the critical elements identified above. To conclude this section, we will illustrate the application of our suggested evaluation survey for the online quot;contexts quot; given in Table5 . First, we consider adjunct applications for any of the training, education, or graduate education contexts.... In PAGE 41: ... This is not necessarily a bad thing: wholly online course taken by on-campus students might be part of the best of both worlds scenario mentioned earlier. In sum, of the seven contexts of online education presented in Table5 , high quality online courses and programs might be developed, with due attention to the paradigm of content delivery and to the establishment of professor-student and student- student interactions, in all contexts except that of whole undergraduate degrees offered online. In this case the needed process of socialization occurs apart from, and indeed is a complement to, the content-delivery experience.... In PAGE 49: ... Stemming from the baby boomlet, the number of young, traditional students will be as high as or higher than ever through the next decade. The seven contexts of online course delivery given in Table5 , for professional training/continuing education, undergraduate education, and graduate education for both traditional and nontraditional students, are all viable contexts in which to implement online teaching, with several exceptions. First, certain types of advanced graduate work, due to the experimental or clinical nature of the work or the type of mentoring, which must occur, cannot be performed online.... ..."

"... In PAGE 2: ... In order to provide comparisons at the approximately similar level of complexity, and to minimize resource overheads and size of the implemented remote system, small topologies are chosen based on past experience and ongoing research [3], [6], [7]. The configuration and training information of the various predictors examined is discussed below and summarized in Table2 . The last column of the table provides the average estimated processing time for the predictors to compress the test data files, as a measure of the performance of the predictors in terms of speed.... ..."

"... In PAGE 15: ... The performance measurements for both cases are calculated from the predicted and actual values of the second half of the data in the time-series. As shown in Table2 , the online predictor outperforms the fixed predictor in every case. We also note that the errors for the three time-series in Table 2 coincide with the estimated prediction difficulty in Table 1 based on SV Ratio.... In PAGE 15: ...

"... In PAGE 12: ... Results and discussion We conducted a number of experiments aiming at comparing the initial feature selection methods, comparing the diC128erent algorithms for text categorization, and at possible improvements by example selection. Table3 summarizes the diC128erent experiments that we have performed. In the following we describe the major findings.... ..."
