Since the publication of Geography for Life: National Geography Standards in the United States (Geography Education Standards Project, 1994), it has been widely used to develop quality curriculum materials for what students should know and able to do in geography. This study compared geography content taught in Omani public schools with Geography for Life standards. Content analysis was used to analyze the extent to which the 18 standards were incorporated into the geography content. It focused on all discrete geography units included in social studies textbooks for Grades (3–10) and two geography textbooks: Economic Geography (Grade 11) and Geography and Modern Technologies (Grade 12). As the study revealed, geography content included good coverage of six standards, including those related to the environment and society. On the other hand, eight standards received less attention in the textbooks, including mental maps and the uses of geography. Findings of the study provided important implications for improving the geography curriculum in Oman. © 2017 Informa UK Limited, trading as Taylor & Francis Group

The present paper deals with a new two-stage testimator of exponential mean - which is obtained by considering a two-stage procedure with appropriate shrinkage weight function. The testimator is based on two classical estimators: by the use of different censored data and by choosing the region R in three different ways when a prior estimate - 0 of the mean - is available from the past. Computer intensive calculations for bias, mean squared error, relative efficiency, expected sample size, the probability of avoiding the second stage sample, and the percentage of overall sample saved expressions show that for different values of the first and second stage samples, for different values of levels of significance, and for varying the constants involved in the proposed estimator, the proposed TSST fairs are better than the classical and existing two-stage testimators.

The objective of this research is an attempt to answering the question "is there a relationship between student's position in a classroom in blended learning and student's academic performance (measured by the total score at the end of the final semester exam)?" The research is one of the correlational studies that uses one way analysis of variance (ANOVA) for statistical data analysis. The sample of study consisted of students of one of the classes (27 students). Each student's position was registered in a classroom map. Student's seat position was gathered by a questionnaire according to student's preference at the beginning of the academic semester (spring 2015). This seat was fixed for all students during the period of the class (15 weeks). Students were categorized into three groups (front, middle, and back) according to seating positions closer to the board. The final score of all students were recorded at the end of the semester for statistical data analysis using ANOVA technique. © 2015 IEEE.

Determining the software quality and release time of the software is an important role of software reliability. Software reliability growth models (SRGMs) are applications of software reliability. The change-point is defined as the prominent change in the software testing time, in connection with the quality of a software error occurrence or error-detection phenomenon. As a result, the software reliability growth process, based on the change-point, affects the precision of the software reliability prediction, based on the SRGMs. To find the accurate total expected delivery cost with a suitable warranty period of the software system, a new cost model for the software system with the warranty and changepoint phenomenon is proposed in this paper. The entire expected delivery cost and the reliability of the software system is calculated using the change-point SRGM. The optimal release time is calculated by reducing the overall estimated delivery cost for various desired reliability levels. Based on the proposed warranty cost model and the reliability of the software system, we have derived some optimal release policies. Numerical illustrations and interconnected discussed data are itemized. From the testing outcome, we get software release policies that provide a comprehensive analysis of software based on the total expected delivery cost with a suitable warranty period, desired level of reliability, and changepoint. Moreover, these policies will be helpful for project managers to decide where to stop the testing for customer release at the exact time with a suitable warranty period. © Tübi·tak.

Studying the inherently high-dimensional nature of the data in a lower dimensional manifold has become common in recent years. This is generally known as dimensionality reduction. A very interesting strategy for dimensionality reduction is what is known as subspace analysis. Beginning with the Eigenface method, face recognition and in general computer vision has witnessed a growing interest in algorithms that capitalize on this idea and an ample number of such efficient algorithms have been proposed. These algorithms mainly differ in the kind of projection method used (linear or non-linear) or in the criterion employed for classification. The objective of this paper is to provide a comprehensive performance evaluation of about twenty five different subspace algorithms under several important real time test conditions. For this purpose, we have considered the performance of these algorithms on data taken from four standard face and object databases namely ORL, Yale, FERET and the COIL-20 object database. This paper also presents some theoretical aspects of the algorithm and the analysis of the simulations carried out. © 2009 Elsevier Inc. All rights reserved.

The marine environment may be explored as a rich source for novel drugs. A number of marine-derived compounds have been isolated and identified, and their therapeutic effects and pharmacological profiles are characterized. In the present review, we highlight the recent studies using marine compounds as potential hepatoprotective agents for the treatment of liver fibrotic diseases and discuss the proposed mechanisms of their activities. In addition, we discuss the significance of similar studies in Oman, where the rich marine life provides a potential for the isolation of novel natural, bioactive products that display therapeutic effects on liver diseases. © 2015 CPS and SIMM.

Conspicuous gaps demonstrate a collective global failure in the world's health systems as they struggle to manage complex and expensive demands. The Lancet Commission recently took a global interdisciplinary perspective and systematic approach to consider alliances between education for health professionals and health systems in order to address these problems. They concluded that positive outcomes require new instructional and institutional designs. Findings from the Lancet Commission have implications for the development of health professional education in Oman, particularly with regard to the call for integrative and transformative education for the next generation of health professionals. Education in the Omani health sector must keep up with increasing challenges in both the health and education sectors.

We present an online algorithm to deal with pattern matching in strings. The problem we investigate is commonly known as 'string matching with mismatches' in which the objective is to report the number of characters that match when a pattern is aligned with every location in the text. The novel method we propose is based on the frequencies of individual characters in the pattern and the text. Given a pattern of length M, and the text of length N, both defined over an alphabet of size σ, the algorithm consumes O(M) space and executes in O(MN/σ) time on the average. The average execution time O(MN/σ) simplifies to O(N) for patterns of size M ≤ σ. The algorithm makes use of simple arrays, which reduces the cost overhead to maintain the complex data structures such as suffix trees or automaton. © Copyright 2016 by SCITEPRESS -Science and Technology Publications, Lda.

There have been remarkable changes in the Omani educational system since the implementation of the Basic Education Reform in 1998. The current study was an attempt to offer insights into the state of geography in the current reform. Particularly, the study examined teachers preferred reasons for teaching geography, teachers views on important topics that should be emphasized in geography curriculum, teachers views on their instructional methods and materials used in geography teaching and teachers views on challenges facing geography teaching. Data were gathered from 144 social studies teachers in Muscat Governorate using a survey. Findings indicated that teachers were interested in a variety of topics, including weather and climate, geomorphology, environmental issues and natural disasters. The most often used instructional methods were discussion, the use of current events, cooperative learning, individual projects, brainstorming and inquiry. Teachers reported using a variety of instructional materials, including textbooks, atlases, maps and globs, the Internet and geographic models. Unfortunately, there were a variety of challenges facing teachers, including the lack of participation in curriculum development. Findings of the study provided important implications for geographic education in Oman. © 2013 Copyright Taylor and Francis Group, LLC.

There is a growing gap between the generation of data and our standing of it. As the volume of data increases, inexorably, the proportion of it that people understand decreases [9]. The enemy of quality is variation. Variation exists in everything. Product quality must be the focus for any process. Through the use of appropriate data mining tools and the concept of statistical reasoning, managers and employees have developed better understandings of their processes. Although they haven't yet figured out how to eliminate variation, data mining has helped in reducing it and in understanding how to operate effectively when it exists. Statistical process control (SPC) can play an essential role in understanding of variation [7]. SPC is an extension of hypothesis-testing and estimation concepts. The utility of statistical process control (SPC) methods has received growing interest in quality assurance to help and improve different processes. The objective of this paper is to provide an overview of X̄ as one of SPC charts, statistical data analysis, and how to benefit from data mining concepts and techniques to get a further insight into SPC design and performance to look for patterns in data and improve manufacturing processes quality control. © 2011 AICIT.
