We examine the prosodic incorporation of utterance-final vocatives in American English. Our report is based on two separate experiments to test the claim by Beckman and Pierrehumbert (1986) ([1]) and Pierrehumbert and Hirschberg ([9]) that the phonetic manifestation of an L* tone on the final vocative is indicative of its contrastive behavior. Our first experiment, involving the dramatic readin...
Abstract This paper presents an appropriate numerical method to solve nonlinear Fredholm integro-differential equations with time delay. Its approach is based on the Taylor expansion. This method converts the integro-differential equation and the given conditions into the matrix equation which corresponds to a system of nonlinear algebraic equations with unknown Taylor expansion coefficients, s...
1.0 overview it seems that grammar plays a crucial role in the area of second and foreign language learning and widely has been acknowledged in grammar research. in other words, teaching grammar is an issue which has attracted much attention to itself, and a lot of teachers argue about the existence of grammar in language teaching and learning. this issue will remind us a famous sentence f...
this study investigates the strategies native english and persian speakers employ for expressing gratitude in different situations. the strategies of persian efl learners are also compared with english strategies in order to find the differences that may exist between these two languages. social status and size of imposition of the favor are social variables which are investigated in detail for...
the following null hypothesis was proposed: h : there is no significant difference between the use of semantically or communicatively translates scientific texts. to test the null hypothesis, a number of procedures were taken first, two passages were selected form soyrcebooks of food and nutrition industry and gardening deciplines. each, in turn, was following by a number of comprehension quest...
We have suggested a numerical approach, which is based on an improved Taylor matrix method, for solving Duffing differential equations. The method is based on the approximation by the truncated Taylor series about center zero. Duffing equation and conditions are transformed into the matrix equations, which corresponds to a system of nonlinear algebraic equations with the unknown coefficients, v...
It is shown, that the mapping class group of a surface of the genus g ≥ 2 admits a faithful representation into the matrix group GL6g−6(Z). The proof is based on a categorical correspondence between the Riemann surfaces and the AF -algebras.
Biodiversity of the genus Medicago in Iran was studied. Distribution of two perennial species M. sativa and M. lupulina mainly conforms to the mountainous regions of Iran. Among the other annual species of this genus, M. rigidula has the most similar distribution to the distribution of perrenial species in mountainous regions. Most species of Medicago (apart from M. sativa and M. lupulina) are ...
the skill of reading in english as a foreign language is an important and challenging one which is affected both by linguistic and extra linguistic factors. since vocabularies are part and parcel of every reading comprehension text, knowing enough vocabulary always facilitates this process. however, guessing strategy as one of the most important strategies has consistently ignored by language l...
this study investigated how group formation method, namely student-selected vs. teacher-assigned, influences the results of the community model of teaching creative writing; i.e., group dynamics and group outcome (the quality of performance). the study adopted an experimental comparison group and microgenetic research design to observe the change process over a relatively short period of time. ...
