in one pole of the continuum of language learning, theoreticians and practitioners traditionally consider english as english as a second language or english as a foreign language. however, in the other pole of this continuum where english is thought of as the most effective tool for international communication, it is referred to as a lingua franca. those who favor an approach to english growing...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
Underwater visual census (UVC) is the most common approach for estimating diversity, abundance and size of reef fishes in shallow and clear waters. Abundance estimation through UVC is particularly problematic in species occurring at low densities and/or highly aggregated because of their high variability at both spatial and temporal scales. The statistical power of experiments involving UVC tec...
Innovation and evolution in sciences needs to its own logical methodology. This paper, considering the necessity of evolution in sciences, has intended to establish a theory called the theory of observation. It would be counted as a model for the philosophies of with a logico-historical approach. Following the purpose, the author has explained technical terms such as research method, theory,...
Methods for improving estimation of cetacean abundance from line transect and markrecapture surveys are proposed. Using either generalized linear or generalized additive models (GLMs or GAMs), two approaches are suggested which allow heterogeneity in the spatial distribution of cetaceans to be modelled from standard line transect data. In the rst approach, the transect lines are divided into sm...
rested on sociocultural theory (sct), this study attempted to examine the effect of written corrective feedback (wcf) followed by producing written languaging on developing writing accuracy over new tasks. to this aim, two intact iranian efl classes at the low-intermediate level were randomly assigned to two experimental groups: direct (n = 25) and indirect (n = 25). both groups wrote on a numb...
efl/esl textbooks have been regarded as essential language teaching materials with which the learners spend about 70 up to 90 percent of their class time. the important role they play and their vast use make them not only influential in learning the language but also in shaping values and attitudes. put it another way, textbooks socialize learners using their contents (i.e. texts, illustrations...
با آنکه دو مفهوم حق و مصلحت از جمله عناصر کلید ی گفتما ن سیاسی، اخلاق ی و حقوقی اکثر کشورهای دنیا قلمداد م یگردند، بروز حدی از تنش میان آنها ب ه دلیل واقعیت تکثر ارزشی و تزاحم ادعاهای متعارض، در عرصه عمل، امری گریزناپذیر جلو هگر م ینماید. ا ز همین روی، نظری هپردازان حوزه فلسفه سیاسی و حقوقی مدرن کوشید هاند تا هر یک به سهم خویش راهکاری را برای حل این تنش مجادل هآمیز ارائه نمایند. از این میان، بر...
for rethinking the anthony giddens’s theory on “reflection”, it is necessary to reconsider his general approach to social reality, and then, situating the concept of “reflection” in the context of his general approach. thus, three-steps will be studied in the article: first, structuration theory that is most important opposition in his social theory. then, giddens's notion of tradition and...
Line transect sampling is a distance sampling method for estimating the abundance of wild animal populations. One key assumption of this method is that all animals are detected at their initial location. Animal movement independent of the transect and observer can thus cause substantial bias. We present an analytic expression for this bias when detection within the transect is certain (strip tr...
