Like a theater person. Disclosures have brought about changes in a person's life. Formed a personality. From the great poems of Ramayana, Mahabharata, and other social events, the stories are classified as Radhanata. The rural artists are depressed without encouragement.

This research investigated the effect of co-curricular activities on academic achievements of special educations students with learning disabilities in SMK Permata Jaya, Rengit, Batu Pahat, Johor, Malaysia. 20 students from special educations class session 2015 were selected for moderate level syllabus and another 20 students were using high level syllabus constituted a study sample. Each level of students taught by the same teacher was divided into experimental and control groups. The experimental groups were involved in co-curricular activities and the control groups did not participate in any co-curricular activity. They were two types of co-curricular activities which are physical activities and the other was like debates, speeches and drama. Raw scores of the students from the subject of Science test made up data for the study. Data analysis involved the use of mean scores and t-test of significant difference between two independent group means scores, supported by F-test of homogeneity of two independent group variances It was found that co-curricular activities had significant effect on academic achievements of the experimental groups.

The effectiveness of mitigation in EIA is vital in preventing adverse environmental impacts thus ensuring sustainable development. However, while EIA has been embedded within the development planning processes in many countries, successful implementation has not been evident in developing countries. Despite EIA being carried out on most development projects there still remains the challenge of implementation of EIA mitigation measures. It’s for this reason that the study evaluates level of implementation of mitigation measures for the selected projects and the utility of EIA mitigation conceptual model in enhancing the effectiveness of mitigation in EIA. A cross-sectional design was adopted to collect and analyse data. Data from thirty (30) EIA reports conducted between 1999 and 2016 were purposively sampled to provide information about the quality of EIA reports in terms implementation proposed mitigation measures. The modified EIS quality review package and mitigation guidelines were used to gather and grade the quality of EIA reports in terms of the impacts and mitigation measures. Regarding the practical implementation of mitigation measures proposed in the reviewed EIA reports, three purposively selected EIA projects, environmental managers, local communities surrounding them and field observations provided the required data. The key findings reveal that the level of mitigation implementation in EIA was partly implemented. Among the six mitigation measures projected, the proponent implemented fully two mitigation measures only relating to impact on land use and impact on soils. The other four mitigation measures relating to air quality and noise pollution control, health and safety, solid waste management and social and economic impacts were implemented partly. The findings of the three projects reveal that mitigation measures are inadequately implemented. The study concluded that EIA reports had shortcomings in impact identification and implementation of mitigation measures. The study recommended that active public participation of local communities can make the implementation of mitigation measures effective.

This paper proposes, with justification, a class of product-cum-dual to product estimators for estimating the population mean in systematic sampling using auxiliary information. The bias and variance of the proposed class of estimators have been derived under large sample approximation. Asymptotic optimum estimator (AOE) and its approximate variance estimator are derived and efficiency comparisons made with existing related estimators in theory. Analytical and numerical results show that at optimal conditions, the proposed class of estimators is always more efficient than all existing estimators under review.

This paper proposed a modified ratio-cum-product estimators of finite population mean using information on coefficient of variation and co-efficient of kurtosis of auxiliary variable in Stratified Ranked Set Sampling (SRSS). It has been shown that this method is highly beneficial to the estimation based on Stratified Simple Random Sampling (SSRS). The bias and mean squared error of the proposed estimators are derived. Theoretically, it is shown that these suggested estimators are more efficient than the estimators in Stratified simple random sampling. The results have been illustrated by numerical examples.

Now a days Public and private organizations increase their database system requirement for day-to-day business. Hence database security becomes more crucial as the scale of database is growing. A signified approach for protecting information which enforcing access control policies based on subject and object and their characteristics. There are many security models for database systems. The database security systems have developed a number of different access control policies for assuring data confidentiality, integrity and availability. In this paper we survey the concepts under access control policies for database security. We review the key access control policies such as Mandatory Access Control policy(MAC), Discretionary Access Control Policy(DAC), and Role Based Access Control Policy(RBAC) and propose a concept on RBAC policy that is instead of access control through role assigned to the users, the users are assigned by some level of access control.

Studies on levels of micronutrients and heavy metal concentration in soils provide vital information for best management options at all times. The study investigated levels of concentration of some heavy metals (Lead-Pb, Iron-Fe, Copper-Cu, Zinc-Zn and Manganese-Mn) on soils along Enugu-Abakaliki major express way in southeastern Nigeria in relation to the environmental and agronomic implication. Forty soil samples were collected at 0-40 cm depth from two environments (A and B). Results showed highly significant (P<0.01) mean lead (Pb) (16.37 mgkg-1) on the soils of Environment A than B (9.5 mgkg-1). Mean Pb in Ishieke I soil was significantly higher (P<0.05) than those of Boundary point II, Ezzamgbo II, and Ezzamgbo. Except Zn that was statistically similar, other metal mean values varied in concentration. Deficiency symptoms of macro- and micro-nutrients were observed on maize and tomato crops. Lime fertilizer was recommended. Continuous evaluation of soils for heavy metals should be an integral part of land use planning for long-term sustainability of farming systems and environmental stability.

Abstract Error analysis is among the interests of many language researchers. Beginning from the times when behaviorism was popular, and following the contrastive analysis studies, error analysis researches have been conducted and researchers aimed at having an insight into language development through their researches. Although language teaching approaches and methodologies have undergone some changes, error analysis still preserves its place in language teaching and likely to keep its significance in the future. This study investigated the erroneous usages of EFL writers through a controlled writing task. Participants of the study were 31 students at Düzce University, Social Work Department, Turkey. The study was conducted in the first semester of 2014-2015 academic year. Student errors that constituted the research data were grouped into 8 categories. The results of the study suggested that the majority of errors were in the conjugation of verbs with a 53.92 percent, where errors of omission, orthography, subject-verb agreement, substitution, word order, addition, and declension of nouns followed respectively. Resulting from the data obtained throughout the study, some instructional implications were provided mainly for the researchers, language teachers, curriculum designers, and coursebook authors.

It is a well-known fact that solar resource or solar radiation varies spatially as well as temporally across the face of the earth. Hence, resource assessment is a preliminary step for all solar applications. In this study, a flat plate surface solar collector of dimension 2 m2, hinged on a horizontal support for quick adjustment of inclination from 0o to 80o was fabricated and marked out at 0.5o intervals on a telescopic leg graduated in degrees. Measurement of the solar radiation, varying degrees of inclination were taken between 11:00 a.m. and 4:00 p.m. for 7 days of each month at clear sky hours. The measurements were made for five months of the year in Tabriz, East-Azerbaijan Province, Iran. These months selected because they have maximum average solar radiation energy in Iran. At each 0.5 degree of inclination, the solar radiation intensity was replicated three times at each hour and the average value was taken. The flat plate was set truly facing south with an engineering prismatic compass. The result showed that the optimum tilt angle of a flat plate for maximum collection of solar radiation intensities in each month. This work also revealed that the average angle of inclination at which a flat plate surface solar collector will be mounted at fixed position in Tabriz is 31o approximately in studied months. The analysis indicated that when a flat surface was located at the forecasted optimum tilt angle for each of five months, solar radiation intensity was increased, when compared with solar radiation intensity harnessed by the same flat plate collector on other angles and under the same condition. Moreover this improvement impose no extra-cost. Comparison of the measured and calculated optimum values of tilt angle of a flat plate surface for trapping maximum solar radiation intensity for each of five months indicated a high correlation with R2 of 0.98 approximately.

Abstract: Dynamic assessment (henceforth, DA) is an approach to assessment which is derived from Vygotsky’s notion of zone of proximal development (ZPD). More precisely, DA is as an alternative to traditional testing which emphasizes greatly on the role of interaction. Recently, the focus of research has shifted from testing listening to teaching it through the use of dynamic assessment; therefore, the present paper aims at reviewing the implementation of dynamic assessment (DA) on listening comprehension. Reviewing the literature has shown that generally dynamic assessment has led learner’s development in listening comprehension. Moreover, the present paper concluded some valuable points. First, group dynamic assessment was conducted in most studies. Second, researchers applied mixed method in their researches. Third, interactionist kind of DA was mainly used and finally lower-intermediate and intermediate learners were the subjects of most studies
