Critical Discourse Analysis (CDA) is a type of discourse-analytical research that primarily investigates the way ideology, dominance, social power abuse, and inequality are enacted, reproduced, and resisted by text and talk (and, more recently, through visual images, sound and other forms of semiosis in the social and political context. This entails a diversity of approaches to CDA research, drawing on various linguistic analytic techniques and different social theories, although all involve some form of close textual (and/or multimodal) analysis. This paper attempts to provide an overview of CDA, the multiple meanings of CDA, and the most important models of CDA, namely Critical Linguistics and Social Model, Relational-Dialectic Model, Socio-cognitive Model, and Discourse-Historical Model.

This paper analyzes the vibration of non-homogeneous transversely isotropic electro-magneto-elastic plate of arbitrary cross-section using the Fourier expansion collocation method. The frequency equations are derived for the arbitrary cross-sectional boundary conditions, since the boundary is irregular in shape; it is difficult to satisfy the boundary along the surface of the plate directly. Hence, the Fourier expansion collocation method is applied along the boundary to satisfy the boundary conditions. The secant method is applied to determine the roots of the frequency equation. The non-dimensional frequencies are computed numerically and are plotted in the form of dispersion curves and further their characteristics are discussed. This problem may be extended to any kinds of cross-sections using the proper geometrical relations.

The purpose of this study is to examine the behavior of exchange rate movements towards foreign direct investment (FDI). Comparative data analysis is applied through answering developed research questions, which are: “What are different types of exchange rate risks that multi-national corporations face?”; “Is there any impact of exchange rate movement on capital market structure of recipient country?”; “Does decision of pioneer Multi-national Corporation affect rivals’ FDI decision?”; and “What is the impact of exchange rate movement on exchange theories?”. Study found that Multi-National Corporations face two main exposures of exchange rate known as cash flow exposure and accounting exposure; exchange rate movements affect market structure; firms follow the rivals in an oligopoly while making foreign direct investment with product differentiation; and exchange rate variations have longitudinal impact on trade theory and state that investment abroad is alternative to trade when free flow of goods is impeded by tariff or other barriers.

Geothermal energy can be used for power generation using thermocouple. In this technology the emission of greenhouse gases has been minimized to zero as compared to 5-7% in geothermal energy by drilling method. The chances of occurring earthquake in thermocouple are limited as compared to drilling method. The results indicate that the temperature ranges from 80-90 0C during the experiment performed under the laboratory condition. It is equal to the approximation recordings from the geo-thermal natural springs. Down fall observed in-between the noon time for the output voltage this is due to rise in the surrounding temperature cause the effects on the performance of the heat sink used. During the noon the mean temperature of the surrounding increase to 40-50 0C, hence mean temperature difference between the source and sink decrease which further causing decrease in the output voltage.

This study investigated the effect of math multimedia teaching on mathematics self-regulation and learning at the junior high school girls students in Iran in the 2012-2013 academic year; and has been performed with quasi-experimental methods (quasi experimental). For this purpose, we selected two classes of first grade school in velayat educational complex in Harsin city (Iran) that have random arrangement and their Mathematics was taught by a teacher; and randomly assigned were considered one class as experimental group and another class as control group. The total respondents were 60 (29 cases in the experimental group, and 31 cases in control group). To collect the data used from regulated learning strategies questionnaire (MLSQ), and were used lesson math final scores for assessing students' learning. After the pretest in two groups, experimental group were taught by multimedia applications, and control groups by common mode. Dependent and independent t-test was used for data analysis. The results showed that, although the self-regulation and academic performance of students with math learning software were taught in the control group was outperformed, But this advantage was not significant at %95 confidence level. Among the reasons for lack of significant assumptions in this study, it can be noted to non-observance of the principles of multimedia in software used, teachers' lack of familiarity with how to use new technologies and how to combine it with traditional, Students' unfamiliarity with new methods of teaching and Students' lack of proficiency in the use of computers.

Maize stover consists of the leaves and stalks of maize plants left in a field after harvest and it makes up about half of the yield and is similar to straw. Ensiling maize stover with urea makes it a urea treated maize stover. Centrosema pubescens is a legume in the family Fabaceae, subfamily Faboideae and tribe Phaseolae. It is native to Central and South America and cultivated in other tropical areas as forage for livestock. An experiment was conducted to investigate the effects of urea treatment on chemical composition; feed intake, blood urea and ammonia of maize stover. The potential of such a stover for growth performance of calves were investigated using 8 N’dama calves of 5 to 8 months of age and an average initial live weight of 92.5 kg. The animals were divided into two groups each of which were individually fed to appetite on basal diets of either untreated maize stover and Centrosema pubescens (Diet T1) or 5 % urea treated maize stover and Centrosema pubescens (Diet T2) for 90 days. In addition all the calves were allowed free access to mineral/vitamin blocks and ample drinking water ad libitum. Urea treatment increased the crude protein (CP) content of maize stover in Diet T2 by 22.12% and also a highly significant difference (p<0.01) in the crude fibre (CF) content over the untreated stover in Diet T1. Besides, compared with the untreated stover, urea treatment brought an improvement of 28% in daily feed intake. These improvements in terms of chemical composition, daily feed intake and dry matter intake led to a highly significant (p<0.01) live weight gain of animals fed on the urea treated stover diet compared with those fed on the untreated stover diet. However, there was no significant difference (p>0.05) in blood urea levels but significant existed in feed cost/kg gain and linear body measurements between the animals fed on Diet T1 and those fed on Diet T2. Generally, with the added advantage of Diet T2 being more cost effective than Diet T1, feeding urea treated maize stover may be considered as one of the strategies that bring about an efficient utilization of crop residues for livestock feeding in Eastern part of Nigeria. However, its economic advantage over other alternatives must carefully be examined under the prevailing price conditions before it is implemented in an area.

The paper sought to assess the effects of multimedia advertisement features on customer satisfaction in 5-star hotels in Kenya. The study was conducted in Nairobi which is the capital city of Kenya between the month of July and September, 2015. The city is endowed with top rated high class hotels ranging from (1) to (5) star luxury hotels which are competing against each other. Classified hotels are trend setters in the tourism and hospitality industry. High classified hotels distinguish themselves by offering superior products and customised services. The mentioned reasons provided a good setup to conduct this research study. The research design for the study was explanatory research design. The target population comprised of the customers of the hotels listed. The total number of hotel rooms from which the sample was derived was 2500 rooms drawn from 15 five-star hotels. Purposive sampling was undertaken in order to distribute the sample size proportionately in accordance to the hotel room capacity. The customers were stratified and then systematic random sampling was used to select the samples who gave responses to the research instruments. The study established that multimedia online advertisement has significant effect on customer satisfaction by improving the interactivity and customer involvement with the brand it also enhances the presentation of the contents.

Abstract. This paper is aimed at finding an optimal estimator of the normal population mean when the coefficient of variation. The paper proposes an “Efficient Minimum Mean Square Error (MMSE) Estimation Approach [Using Two ‘Sample Standard Deviation’, for improving the well-known Searls’ Usual MMSE Mean Estimator (1964)] for Normal Population with Known Coefficient of Variation”. The ‘Relative Efficiencies [as compared to the usual unbiased sample-mean estimator ] estimator, per the proposed approach, has no simple algebraic form, and hence is not amenable to an analytical study determining its relative gainfulness, as compared to the usual unbiased sample mean estimator. Nevertheless, we examine the relative efficiency of our estimator with respect to the usual unbiased estimator , using an illustrative simulation study with high replication. MATLAB R2013a is used in programming this illustrative “Simulated Empirical Numerical Study”.

Concerning the increasing incidence of temporomandibular joint disorders and their impact on health status, this study was conducted to assess the knowledge of general dentists and dental specialists on temporomandibular disorders (TMD) in Shiraz.A questionnaire including 20 questions about knowledge of anatomy, signs and symptoms, diagnosis and treatment was given to 50 randomly selected general dental practitioners and specialists, in Shiraz, Iran. The answers were analyzed with SPSS14. Out of 50 participants consisting of 26 men and 24 women (mean age of 38.9±10.8 and mean years of practice 12.5±10.4), 41 were general dental practitioners and 9 were specialists. Mean score of diagnosis and treatment knowledge of all participants was 27.4 ±4.9 out of 40 achievable scores. There was a significant difference between the knowledge of specialists and that of general dental practitioners (P < 0.05). Age, gender, years of practice and university of education did not make any significant difference to the scores.The results of this study indicated an acceptable knowledge of participants regarding TMD.
