This research examines the influence of motivation towards academic achievement among gifted students in Saudi Arabia. The discussion in the study is base on the theoretical framework of the emotional intelligence Theory Goleman’s (1995), the Mayer and Salovey Model (1995) and achievement motivation Theory. These theories are appropriate for the study because they allow the reader to understand how academic achievement is significantly influenced by motivation among gifted students in Saudi Arabia.

The purposes of this research were to study the influence of social media on customer’s perception, case study PTT Public Company Limited (PTT) in order to measure the performance and propose the development approach. The sample were 400 customers living in major provinces around Thailand, aged over 18 years old and used social media in daily basis. Both quantitative and qualitative research methods were conducted. For quantitative method, data was collected by simple random sampling through questionnaires. Frequency, percentage and chi-square test were applied as statistical analysis tools. Statistical significance levels were set at .01 and .05. For Qualitative method, both in-depth interview and content analysis of online news about PTT were conducted by descriptive method. The study indicated that PTT's social media had the potential to provide relatively positive information at a moderately high level. This was good for the image and business. (products and services) of PTT both In terms of public relations and clarification. As for the suggestions for improvement included: 1. It was new media that did not cover all users. Therefore, it should be used in conjunction with traditional media. 2. It should be organized collected and integrated to be convenient to use. 3. There should be strategies to present it in a timely manner and be able to create a sense of togetherness. And 4. There should be a good content creation process to increase the positive impact and reduce the negative impact in order to enhance the customers to get good value from PTT.

The purpose of this study was to see whether any significant relationship exists among EFL learners’ self-esteem, autonomy, and reading comprehension; and whether there is any significant difference between EFL learners’ self-esteem and autonomy in predicting their reading comprehension skill. For this purpose, 121 EFL participants who were studying English Language Literature and Translation at Islamic Azad University Central Tehran Branch, were randomly selected. The researcher tested different ranges of students with different levels of proficiency. The Coopersmith self-esteem inventory, autonomy questionnaire and reading comprehension section of Preliminary English Test (PET) were administered. Correlation and regression analysis demonstrated that there is a significant relationship among EFL learners’ self-esteem, autonomy, and reading comprehension. There is also a significant difference between EFL learners’ self-esteem and autonomy in predicting their reading comprehension.

The purpose of this study is provide some insight into the role played by emotional intelligence in the effectiveness of a leader. The general objective of this research study is to establish the relationship between emotional intelligence and effectiveness of a leader. Specific objective is to understand the role emotional intelligence plays in effectiveness of a leader. The null hypothesis of this study is there is no relationship between emotional intelligence and leadership effectiveness. The study is built on the general belief that leaders are human beings who have human feelings. Therefore, one who is emotionally intelligent might use emotion to create charismatic authority over team members in order to ensure team transformation. It is assumed that effective leaders may not necessarily be people with very high intelligent quotient but those intelligent people who are well able to manage their emotions to suit the present situations. In the recent past, there has been a rise in cases of prominent people and leaders in organizations losing jobs because of their inability to balance between their emotions and job requirements. Cases of stressed workforce have been rising. This prompted this research. Ferris (2002) emotional intelligence is a construct that is gaining a lot of attention because many very learned leaders have been failing in their leadership just because of not balancing between emotions and intelligence. Sosik and Megerian (1999) stated “emotionally intelligent leaders provide the impetus for individuals to collectively perform”. The methodology of this study will be combined research design. Purposeful sampling will be used to sample the population. In this regard, three different cases have been identified to support this proposition and understand the nature of relationship between emotional intelligence and leadership effectiveness. The caseswere drawn from major banks in kenya. The researcher concludes that effective leaders are those who able to balance between their moods and emotions at the workplace in order to influence their employees positively and also well manage others at work

Student violence has been a problem in the Kenyan educational system for a long time now. The first case of student unrest in Kenya was reported at Maseno School at the beginning of the 20th century (1908). To date, the situation is still unabated. The trend is rather alarming and the magnitude of violent acts by students is high and worrying. The paper therefore using a random sample of 251 students who were selected from five purposively chosen secondary schools in Njoro division were interviewed using a standardized research questionnaire. The students were selected using a combination of stratified random sampling and the systematic sampling techniques, which are probability sampling procedures. The data collected was analysed using both the descriptive and inferential statistics. It was found out that three factors related to the school social environment determined the students’ participation in violence in secondary schools as discussed in this paper. The paper recommends that there should be a better understanding of the school social environment factors as aggravators of student violence in secondary schools.

This study is relating to the study of relation between the level of using internet among juveniles and their tendency to delinquency. In this study that has been performed as one field we study meaningfulness of the relation between the juveniles who use internet and non users based on the tendency to the delinquency and it is determined that there is a meaningful relation between the level of using internet among juveniles and their tendency to delinquency

The main aim of this study is analysis of relationship between organizational justice and knowledge management. This analysis is based on descriptive analysis and from survey branch. Information gathering means is questionnaire, and in order to organizational justice analysis Chester and Ted (2007) 20 scores questionnaire is used and for knowledge management evaluation is the 21 questions questionnaire of Proset et al. For determining acquired data Kolmogorov -Simonov test is used and results confirm data normality. Used test in this analysis are correlation spearman test, line regression test, T-test and Friedman test and with using related test confirmed research propositions; results shows that in the aim community with improving organizational justice and knowledge management in staffs is increased too, line-regression results between organizational justice and knowledge management shows that between inter organizational justice as a independent variable and knowledge management there is linearity relationship.

Business intelligence systems combine operational data with analytical tools to present complex and competitive information to planners and decision makers. The objective is to improve the timeliness and quality of inputs to the decision process. Business Intelligence is used to understand the capabilities available in the firm; the state of the art, trends, and future directions in the markets, the technologies, and the regulatory environment in which the firm competes; and the actions of competitors and the implications of these actions. The emergence of the data warehouse as a repository, advances in data cleansing, increased capabilities of hardware and software, and the emergence of the web architecture all combine to create a richer business intelligence environment than was available previously. Although business intelligence systems are widely used in industry, research about them is limited. This paper, in addition to being a tutorial, proposes a BI framework and potential research topics. The framework highlights the importance of unstructured data and discusses the need to develop BI tools for its acquisition, integration, cleanup, search, analysis, and delivery. In addition, this paper explores a matrix for BI data types (structured vs. unstructured) and data sources (internal and external) to guide research.

The diffusion equation is solved in two dimensions to obtain the concentration by using separation of variables under the variation of eddy diffusivity which depend on the vertical height in unstable case. Comparing between the predicted and the observed concentrations data of Sulfur hexafluoride (SF6) taken on the Copenhagen in Denmark is done. The statistical method is used to know the best model. One finds that there is agreement between the present, Laplace and separation predicted normalized crosswind integrated concentrations with the observed normalized crosswind integrated concentrations than the predicted Gaussian model. One gets that the four models are inside a factor of two with observed data. Regarding to NMSE and FB, the present, Laplace and separation predicted models are well with observed data than the Gaussian model. The correlation of present, Laplace and separation predicated model equals (0.52, 0.64 and 0.60 respectively) and Gaussian model equals (0.80).
