ABSTRACT: The present research was aimed to evaluate landslide susceptibility in Chamran basin using tow quantitative models of LNRF and weighted semi-quantitative (AHP (Analytical Hierarchy Process) - area density). For this, using interpretation of aerial photographs and satellite Google Earth, GPS devices and reconnaissance, landslide distribution maps in scale 1:100000 were prepared in points manner, included 30 landslide cases of which , inspired from common methods, 30% (nine) were randomly selected and used to evaluate the performance of the models and the rest ( 21) were used for modelling . Seven key factor in the occurrence of landslide were selected including distance to river, distance to road, lithology, land use, slope, aspect and altitude. Information layers related to each parameter were prepared in GIS. Susceptibility value was calculated multiplying parameters value by parameter class value and landslide zoning map was prepared based on summing these values and pixels cumulative frequency turning points (Natural breaks). Models Performance was tested using indices summation of quality (Qs), the precision of predicted results (P) and relative performance characteristic (ROC). The results of indices showed that the weighted bivariate statistical model (AHP - area density) is more efficient for landslide distribution in area Chamran.

ABSTRACT: Cyanobacteria, known as blue-green algae, blue-green bacteria, cyanoprokaryots, and cyanophytes, are oxygenic photosynthetic prokaryotes Cyanobacteria show considerable morphological diversity. They are morphologically, physiologically and metabolically very diverse group and have been the thrust area for investigation since long. The blue-green algae are considered to be thermophilic when part or all of their optimal growth temperature range is above 40°C. Only a few species of eucaryotic protists or animals tolerate higher temperatures. Hot springs and their drain ways provide the most abundant aquatic habitats for thermophilic blue-green algae. Therefore, The present investigation involves study of mat forming cyanobacterial flora from Lamazan hot springs located in west part of Hormozgan province. This thermal spring are inhabited by characteristic thermophilic organisms including cyanophyta. Cyanophyta are among the few organisms that can occupy high temperature aquatic environments including hot springs. In alkaline and neutral hot springs and streams flowing from them cyanophyta can form thick colourful mats that exhibit banding patterns. Sampling was done based on temperature gradients; physicochemical analysis of the water was performed due to a dramatic effect on species distribution, Samples collected at different temperature ranges and were divided into two parts, One part was fixed in 4% formaldehyde to minimize quantitative and qualitative changes in phytoplankton and the other part were kept in a refrigerator for provide the pure isolates. Taxonomic determination was carried out by morphometric study of the isolates with light microscopy, based on Desikachary, Prescott, Whitford and Schumacher, John et al. and Wehr et al. by prepared semi-permanent slides. The vegetative and reproductive characters used in the taxonomic determination were: shape, colour and size of the cell, colony, thallus and trichome; as well as their width and length; shape, size and colour of vegetative cells. As result of this study, Total of 23 thermophilic cyanobacterial species representing 2 orders, 6 families and 10 genera were recorded.

ABSTRACT: The objective of this study is to investigate the pattern of structural relationships between perceptions of constructivist learning environment, academic self-efficacy, intrinsic motivation and academic performance of students in Islamic Azad University of Minab. In this descriptive-correlational study, the population is all students in Islamic Azad University of Minab and using multi-stage random sampling, 400 students in various disciplines are selected as samples. Tools used in this study include Constructivist Learning Environment Survey (CLES) and Motivational Strategies for Learning Questionnaire (MSLQ). The proposed model is evaluated using structural equation modeling. To test indirect relationships, Bootstrap test is conducted in Hayes and Preacher macros. According to the results obtained in this study, the proposed model for structural equations of causal relationships between variables indicates an acceptable fitting. Based on the results obtained for assumptions one to five, we can conclude that the indirect relationships proposed in assumptions sixth and seventh are also explainable. In other words, the perception of a constructivist learning environment can affect academic performance through increasing the academic self-efficacy and intrinsic motivation, and promote it.

ABSTRACT: Feedback has been considered as a remedial measure and consequently a substantial body of research has been done over the last decades into the value of different kind of responses offered to students and their effects on student performance. Feedbacks are commonly categorized based on Lyster and Ronata’s model of corrective discourse which sorts them into six classes including explicit correction, recast, clarification request, metalinguistic feedback, elicitation and repetition. Many studies are conducted on the effect of different types of spoken error correction in Iranian EFL classes and the type of feedback which is mostly used by teachers (but very few studies are carried out on finding teachers’ intentions of preferring a certain type of feedback over other types. The present study explored the reasons of using recast as the most frequent type of corrective feedback in Iranian EFL context. Data was collected from 100 Iranian EFL teachers from different parts of Iran; they filled in a questionnaire in order to find the reasons of their preference. The study revealed that teachers rely on aspects of error correction such as being short, immediate and to the point as well as saving learners from negative feelings that does not fully go with what is likely to facilitate learning and increase uptake rate.
