the purpose of the present study was to compare writing high achievers and low achievers tefl (teaching english as foreign language) learners’ writing self-beliefs. subjects, based on their officially recorded scores on the writing course, were assigned in two 22-member groups of high and low achievers. the adapted english version of mills’ and péron’s (2008) questionnaire and the foreign langu...

logit models are one of the most important discrete choice models and they play an important role in describing decision makers’ choices among alternatives. in this paper the multi-nominal logit models has been used in mode choice modeling of isfahan. despite the availability of different mathematical computer programs there are not so many programs available for estimating discrete choice mode...

in the present paper, resonant frequencies and modes of a three-atom photonic molecule and a photonic crystal placed within a cavity are numerically calculated. first, governing formulation in transverse electric field mode (te) is obtained using maxwell equations. then, an algorithm based on a finite difference scheme and matrix algebra is presented. the algorithm is then implemented in a comp...

width of less than or equal to 8 pm operate in a single mode, but the waveguides with a core width of more than 8 pm operate in multiple modes. Figure 3 shows the dependence of optical loss on core width. The optical loss is constant for TE polarized incident light, even though the core width increases. On the other hand, the optical loss decreases with increasing core width for TM polarized in...

In an influential paper, Béatrice Bourdin and Michel Fayol (1994; and subsequently 2000, 2002) explained, in terms of cognitive load, that low-level processes of written language production are more difficult than those involved in oral language production due to the cognitive costs of grapho-motoric and orthographic behavior. Their results were obtained with mother-tongue speakers of French, a...

342 David Gisselquist, John Potterat and Stuart Brody, writing recently in the SAMJ, suggest that the high prevalence of HIV among infants and children in sub-Saharan Africa is a result of iatrogenic transmission of HIV, rather than mother-to-child transmission (MCTC). Earlier, the same group have suggested that unsafe injections are a major, if not the main, mode of transmission of HIV-1 in su...

Digital technology has an increasing influence on writing processes. In this context, the question arises whether changes in mode (i.e., handwriting vs. computer-keyboard typing) also require assessments. However, data directly comparing influences children with and without developmental deficits are scarce. This study investigated of German-speaking, typically developing dyslexia (DD) from two...

Peer response is useful to improve student writing. However, traditional peer response takes a single mode, which has some problems, such as effort for preparation of documents or ambiguous feedback. To address these problems, this study presents two peer response approaches, that is, an integrative approach and a game-based integrative approach. Additionally, whether students with these two pe...
