An-Nukat al-Ḥisān fī sharḥ ghāyat al-iḥsān of Abū Ḥayyān an-Naḥwī al-Andalusī ; a critical edition with an introductory study

This thesis consists of an annotated edition of a manuscript of Abu Hayyan an-Nahwi al-Andalusi and an introductory study. The introduction falls into three main sections, the first being a study of Abu Hayyan's life and the characteristic features which contributed in forming his character like his upbringing, education, teachers, belief and knowledge. We concluded this section by pointing out his extensive and varied knowledge not only of Arabic and Islamic disciplines but also his knowledge of foreign languages, Turkish, Persian, Ethiopic and Coptic. We also mentioned the high status he occupied as one of the most distinguished scholars of his time and probably one of the most outstanding Arab grammarians for his works on the study of Arabic grammar and the foreign languages

Re-ranking Real-time Web Tweets to Find Reliable and Influential Twitterers

Twitter is a powerful social media tool to share information on different topics around the world. Following different users/accounts is the most effective way to get information propagated in Twitter. Due to Twitter's limited searching and lack of navigation support, searching Twitter is not easy and requires effort to find reliable information. This thesis proposed a new methodology to rank tweets based on their authority with the goal of aiding users identifying influential Twitterers. This methodology, HIRKM rank, is influenced by PageRank, Alexa Rank, original tweet or a retweet and the use of hash tags to determine the authorisation of each tweet. This method is applied to rank TREC 2011 microblogging dataset which contains over 16 million tweets based on 50 predefined topics. The results are a list of tweets presented in a descending order based on their authorities which are relevant to the users search queries and will be evaluated using TREC’s official golden standard for the microblogging dataset

EFL Teachers’ Views about their Roles in the Curriculum of the EFL Foundation Year Programme in Saudi Arabia

This research is an exploratory study that investigated teachers’ roles in an English as a Foreign Language (EFL) curriculum within a Foundation Year Programme (FYP), at an English Language Institute (ELI) in one of the public universities in Saudi Arabia. The study focused on teachers’ roles in three different stages of the curriculum: development, implementation and evaluation. The participants of the study were twenty-two expatriate and Saudi EFL teachers, male and female, with experience in teaching in the FYP. The study adopted an interpretive approach to address the issues under investigation. Three research questions were raised to address the teachers’ roles in each area separately. Data were obtained through semi-structured interviews with teachers. Based on interpretative principles, data were analysed in the form of explanation and interpretation of the participants’ views about their roles in the investigated stages of curriculum. The findings indicated that EFL teachers had limited roles in the curriculum development process as they participated in only two different curriculum development tasks: the pre-use course book selection and the students’ language needs analysis. In the implementation stage, teachers were more active as they reported that they had the freedom to develop and use their own supplementary teaching materials in addition to having the freedom to adopt the teaching methodology they felt was appropriate for their students. In the evaluation stage, the teachers reported different levels of involvement in the evaluation of certain curriculum elements selected by the ELI administration, namely, course books, pacing guide, tests, the module system and students’ portfolios. Finally, teachers offered various suggestions for engaging them more actively in the curriculum decision-making process in the three stages of curriculum. The study made some recommendations for improving teachers’ roles in the development, implementation and evaluation stages of the curriculum for future consideration

Developing network leadership in planned organisational change: the emergence of transformation network leadership

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University LondonAccording to the literature, Network Leadership is defined as a leadership approach that influence the interaction mechanisms between actors and nodes connecting scattered organisational clusters to achieve the collective organisational goal. Network Leadership is based on network leaders’ attributes and practices to connect scatter clusters across organisational boundaries. Literature suggests that Network Leadership is to be further explored and examined to capture its conceptual dimension. Taking Network Leadership as useful but underdeveloped concept, this study brought together existing knowledge from distributed leadership and organisational transformation and examined the intersection of these two domains through the theoretical lens of social network theory. This research develops the Network Leadership literature by introducing the phenomenon of Transformation Network Leadership, which shifts leadership theory and practice away from reliance on single change agents towards the creation of a network of transformation leaders to implement planned organisational changes. This study details the conceptual characteristics of Transformation Network Leadership and demarcates it by specifying its essential features: Network Leaders Attributes and Network Leaders Practices. The theoretical contribution of this study is demonstrated by analysing critically Transformation Network Leadership, drawing upon Whetten (1989), to identify its components, to postulate relationships between the components and to suggest conditions under which Transformation Network Leadership is more or less likely to support the implementation of planned change initiatives. This study’s ontological and epistemological position is interpretivist / constructivist. The findings are based on an in-depth, qualitative study conducted within Bahrain’s Oil and Gas sector. The unit of analysis is the companies operating in Bahrain Oil and Gas. Data was gathered using semi-structured interviews and data analysis conducted using thematic analysis technique. The limitations of the study are conducting the study in Bahrain Oil and Gas, qualitative methodological approach, and the limited sample size. Future research directions are examining the intersection between distributed leadership with organisational transformation, examining Transformation Network Leadership on a broader scale and expanding the research to regional and international context. Future research can be extended beyond the scope of this research to other sectors as well as carrying out quantitative research to examine Transformation Network Leadership

EEIT2-F: energy-efficient aware IT2-fuzzy based clustering protocol in wireless sensor networks

Improving the network lifetime is still a vital challenge because most wireless sensor networks (WSNs) run in an unreached environment, and offer almost impossible human access and tracking. Clustering is one of the most effective methods for ensuring that the relevant device process takes place to improve network scalability, decrease energy consumption and maintain an extended network lifetime. Many research have been developed on the numerous effective clustering algorithms to address this problem.  Such algorithms almost dominate on the cluster head (CH) selection and cluster formation; using the intelligent type1 fuzzy-logic (T1-FL) scheme. In this paper, we suggest an interval type2 FL (IT2-FL) methodology that assumes uncertain levels of a decision to be more efficient than the T1-FL model. It is the so-called energy-efficient interval type2 fuzzy (EEIT2-F) low energy adaptive clustering hierarchical (LEACH) protocol. The IT2-FL system depends on three inputs of the residual energy of each node, the node distance from the base station (sink node), and the centrality of each node. Accordingly, the simulation results show that the suggested clustering protocol outperforms the other existing proposals in terms of energy consumption and network lifetime
