    Molecular Evolution is the key to explain the divergence of species and the origin of life on earth. The main task in the study of molecular evolution is the reconstruction of evolutionary trees from sequences data of the current species. This thesis introduces a novel algorithm for inferring evolutionary trees from genetic data using quartet-based approach. The new method recursively merges sub-trees based on a global statistical provided by the global quartet weight matrix. The quarte weights can be computed using several methods. Since the quartet weights computation is the most expensive procedure in this approach, the new method enables the parallel inference of large evolutionary trees. Several techniques developed to deal with quartets inaccuracies. In addition, the new method we developed is flexible in such a way that can combine morphological and molecular phylogenetic analyses to yield more accurate trees. Also, we introduce the concept of critical point where more than one possible merges are possible for the same sub-tree. The critical point concept can provide information about the relationships between species in more details and show how close they are. This enables us to detect other reasonable trees. We evaluated the algorithm on both synthetic and real data sets. Experimental results showed that the new method achieved significantly better accuracy in comparison with existing methods

    This thesis investigates the effect of monetary policy on financial stability and part of the real side of the Jordanian economy over the time period 1976-2009. It uses a number of empirical methodologies including: a Vector Autoregressive (VAR) to investigate the relationship between monetary policy and financial stability in Jordan; A Logit model and Markov switching model to study the currency crisis in Jordan; and an Autoregressive Distributed Lag (ARDL) to estimate an investment function for the Jordanian economy. Findings of the VAR models confirmed the relationship between monetary policy and financial stability in Jordan. However, a number of indictors were found to have a significant effect on the currency crisis in Jordan. These indictors included the real exchange rate, money supply-reserves ratio, and growth rate of domestic credit. On the other hand, a stable long-run investment function exists. Real income and real credit were found to have a positive impact on real investment. However, the user cost of capital has had a negative impact on real investment

    Combating the Misrepresentation of Women in Quran Translations: Translational Interventions

    Get PDF
    The discourse concerning Islam, and in particular the translation of the Quran, has had a profound impact on Western views of Muslim women. Most Quran translations are stained with mistranslations, resulting from translators adopting the literal approach for religious reasons that we will explore. This has an impact on many aspects of meaning, but especially the representation of women. It should be noted that this article is not influenced by the views of feminist groups who focus on seeking new interpretations of the Quran. Instead, it pinpoints the genuine interpretation lost in translation. This article endeavors to identify the translational mistakes, and their influence on the image of women, through a comparison with the original text in terms of linguistic and paralinguistic features found in the Quran. The article adopts the interpretive approach in the form of a multiple-case study to clarify the mistranslated cases and to provide genuine interpretation as understood within the original context, without either addition or omission. The article concludes that many Quran translations instantiate a fertile ground, contributing to the creation of a negative image of Muslim women in the eyes of the West. This is attributed to the translator’s lack of knowledge of Quranic scholarship, i.e., the paralinguistic issues and the excessive use of the literal approach that fails to capture the intended meaning of the original text

    This paper is based on the findings of in-depth face-to-face semi-structured interviews with owners, directors and senior managers of twenty contractors' organisation in the United Arab Emirates construction industry. Then the research findings were reported and sent back to those who participated in the interviews in a form of a validation report for their review and comments.  The objective of this paper is to explore the marketing concept, cost and activities within the contractors’ organisation in the United Arab Emirates construction industry. The results indicated that marketing function has been slightly accepted as legitimate management activities in the UAE construction organisations (15% of respondents). Furthermore, the majority of companies (80% of respondents) consider marketing cost as a wasting of money since most projects were awarded to the lowest price offer. More than 85% of the interviewed contractors indicated that they do not have marketing departments or divisions in their companies; instead they have a public relationship department with the focus on the documentation of current project and the internal magazine of the company. Only 15% of contracting companies have a separate marketing division with a few staff and little budget. The result also indicated that there is much confusion among contractors on the definition of the marketing concepts and its purpose and activities.

    This paper examines the role of cultural factors in software development, such as management of communications, distribution of project information, behaviors and attitudes. The study population consists of all Jordanian institutions (n = 96) operating in the field of software development. From previous studies that have been reviewed and applied study conducted by researchers at the Jordanian companies show us the importance of cultural factors. It is therefore important for the project team to deal with these factors in a serious and careful. Should the project manager and his team  they have a good knowledge in how to deal with these factors. It should be the project manager and his team have their efficiency in the process of comparison between the benefits of the proposed system do not exist in the old system for each of the groups and individuals in the organization, and convince them of the benefits gained from the proposed system better and more for individuals and groups in the organization of the current system the old one.

    The aim of this study is to reveal the typical effect of Advanced Regulator controlling the survey of critical thinking skill in the National Study of Civic Education and Tenth Grade Students in the development of Jordan. The study population consisted of all tenth grade students in schools which included at least two divisions. However, this included the grade in the education directorate which is the banner of the southern shrine. The study sample consisted of 120 students from students in school communities. They included 40 male students and 80 female students, which were spread over four study group. Two of the four divisions in each school were taught the Advanced orderly pattern, while the other two divisions were taught the Achtbaraltvkir critic preset. This arbitration process procedure was carried out to test the equality of the groups. After a dimensional treatment, the collected data were statistically analyzed using statistical software (SPSS) and statistical processor Pearson correlation coefficient. The forgoing analysis were done to test the stability of the expense, as well as the calculated circles and standard deviations, in order to make comparisons. Furthermore, the results of the two-way analysis of variance ((2x2) Two-way ANOVA) was also extracted. The results showed that there were no statistically significant differences at the level of significance (α> 0.05) in the skill of critical thinking development, due to the pattern of teaching or the interaction between style and gender. There were statistically significant differences at the same level of significance attributed to gender (male and female) and in favor of female students. The study concluded with recommendations in their entirety focus attention on the need for modern teaching patterns, as well as critical thinking skill to give a greater share in the area of curriculum
