Developing valid measures of abstract constructs is essential to the advancement of psychological and educational research. The most common practice in scale development consists of an administering a group of items intended to measure the same construct and subsequently aggregating the responses to form total a scale value. Besides, reliability of scores, number of underlying constructs, and scale construction practices should empirically test the assumptions of equal item weighting and the linear treatment of scales can represent the quantity of a trait held by an individual. Based on the perspective of using Rasch Model as a model in one sense in that it represents the structure which data should exhibit in order to obtain measurements from the data; i.e. it provides a criterion for successful measurement. As such, measuring the lecturers¿ beliefs needs a measurable instrument to be developed and tested in order to clarify how beliefs reform lecturers¿ teaching functions and practices. This book is mainly on how to use Rasch Model analysis as a powerful tool for evaluating constructs validity of the instrument for interpretation the lecturers¿ beliefs on teaching functions.

Sudan is considered a multi ethnic, regional, cultural and religious ingredients country. As a result of this diversity the ingredients engaged in numerous civil wars. The conflict of South Sudan was the first and largest; In return, many efforts were made to solve this conflict; the last was the CPA signed in Nivasha in 2005; which put an end to the South war, and granted the people of South Sudan the right of self-determination by the end of the transitional period in 2011. In the end, the Southerners chose separation and declared the South Sudan State. The secession was the result of several factors which collaborated together and both North and South Sudan were affected negatively. This discussion targeted to research these means by its internal and external sections; also the result of secession of both sides. The study also targeted the analysis and evaluation of the CPA and quest of the possibility of unity between North and South once more.

Writing is not a simple activity as a few people may consider; it is a sort of challenging task, when it is compared with various language abilities, such as reading, listening and speaking which needs a lesser amount of effort. Writing is a significant challenging process, especially for second language learners and foreign language learners. Most language learners at all stages feel that writing is probably the most challenging language ability to be mastered and it is a progressing advanced skillfulness in contrast with other capacities. Writing in English is supposed to stand as a critical talent for accomplishment in the current international economy. Several specialists would go further to say that when there is a lack of experts in English reading and writing, a job would be slightly inadequate if it includes doing business in English-speaking countries at even a fundamental level. Consequently, it is suggested that English writing becomes a need for any comprehensive director who needs to develop his or her career in the universal market.

Bioinformatics has been evolved into a critical inter-disciplinary field that benefits studies in both molecular biology and computer science. On the one hand, it grants the possibility to comprehend biological information and process in a more effective and efficient way by employing computational technologies to extracting knowledge from dense amounts of intermixed biological data; on the other hand, it provides a new and complex domain for researching advanced algorithms and techniques for data analysis. Nevertheless, bioinformatics also poses a great challenge to grasp for both computer science and biology majors due to its interdisciplinary and advanced natures. As many bioinformatics software tools are generally involved in analysis tasks, scientists are more and more requiring that these heterogeneous bioinformatics tools be integrated in a uniform way. They are also requiring graphical user interfaces of these tools, and the ability to compose workflows without much programming effort.

In the last 15¿20 years, pulsed laser deposition (PLD) has emerged as one of the most popular and intrinsically simple techniques for depositing a wide range of the most exciting materials being explored for next generation applications. Such sustained popularity is due to the inherent versatility, flexibility, and speed of a process that can be applied to essentially any material, from simple metals, through binary compounds, to multi-component high-quality single crystals. Pulsed laser deposition had several characteristics that made it remarkably competitive in the complex thin-film research arena as compared to other film growth techniques. These principle attractive features were stoichiometric transfer, and simplicity in initial setup and in the investigation of arbitratry compounds. One could rapidly investigate thin-film deposition of nearly any compound regardless of the complexity of the crystal chemistry.

This book gives necessary information about Human speech production and mechanism which is very important for English language learners to develop their communicative efficiency Like other English language skills or sub skills courses, such as reading, writing, grammar and vocabulary etc., It is one of the basic skills required for the learners in their English language learning. As shown in this study, certain English consonant sounds are difficult to pronounce or to know its mechanisms and methods of production.

In this book, three methods of estimation are employed to determine the estimators of the shape and scale parameters of Pareto distribution. The bias, variance and mean square error are used as measurement of the performance of these methods. The simulation technique is used to obtain a required results. The Kolmogorov-Smirnov (K-S) goodness of fit test is used and finally, some real life applications are presented.

Multicomponent reactions (MCR¿s). leading to interesting heterocyclic scaffolds have emerged as powerful tools for the diverse needs in combinatorial approaches for the synthesis of bioactive compounds, creating distinct chemical libraries of drug-like molecules for biological screening. Spiro compounds represent an important class of naturally occurring substances with highly pronounced biological properties.Spirooxindole ring systems are found in a number of alkaloids, such as horsifiline, spirotryprostain, and (+) elacomine, and are used in biological applications as antimicrobial and antitumor agents and as inhibitors of the human NKI receptor. Additionally, spirooxindole rings containing the pyrrolidine and pyrrolizine ring system are found in various natural products as fundamental nuclei and are well recognized for exhibiting a wide range of pharmacological and biochemical behaviors.

This book is one of the important books on Henry James's view of psychological realism. It is an attempt to show, through analysis and close observation, the technique James adopts in portraying his protagonists. James's way of characterization and his ability to observe and to reflect the subtle nuances in the human psyche is impressive. As a consequence, his mastery in mirroring the inner conflicts and the other transformative processes happening inside his characters, just as they really are, is unrivaled.

The World Health Organization recommended modern contraceptive services, including emergency contraception, as a means of reducing unsafe abortions and maternal mortality. These complications can be avoided through the use of emergency contraception. It is a form of modern contraception that is used after unprotected sexual intercourse, sexual abuse, or the use of regular contraception. It plays a vital role in preventing unwanted pregnancy and thus helps to reduce unsafe abortions or unwanted children, which is a major health problem among mothers. The means are used within 72 hours of unprotected sexual intercourse. Governmental and non-governmental organizations working to provide reproductive health services to these women may benefit from the results of this study by providing awareness programs.

This study was conducted with the objective of enhancing salt tolerant in two rice (Oryza sativa L.) genotypes grown widely in Iraq, namely Amber 33 and Amber Baghdad which are sensitive to salinity. In this study, many experiments were carried out to investigate DNA markers associated with salinity tolerance by inducing genetic variation using Ethyl Methane Sulphonate (EMS) and UV-B (320 nm) radiation as a mutagen and then selecting tolerant plants. The first experiment included screening the sensitive genotype seedlings for salinity tolerance using Murashige and Skoog, 1962 medium (MS) supplemented with different sodium chloride (NaCl) concentrations. Seeds of two rice genotypes Amber 33 and Amber Baghdad were inoculated into half strength MS medium supplemented with 0.0, 50, 100, 150, 180 or 200 mM NaCl. The effect of NaCl was examined on seed germination, shoot height, root length, root number, and activities of antioxidative enzymes (peroxidase, catalase and ascorbate peroxidase). Addition of NaCl resulted in decreasing the means of all studied characters with increasing NaCl concentration except the activities of antioxidative enzymes since they increased significantly.
