An Investigation of Pre-Service Teacher Preparation Programs in Teacher Education and Co-Teaching Models

This qualitative investigation centers on pre-service teacher training programs that effectively promote inclusive education and co-teaching. The study employed a purposeful sampling technique to select participants who possessed knowledge and experience in pre-service teacher preparation programs and co-teaching methodologies. The sample included pre-service teachers and teacher educators. The study employed thematic analysis as a method for interpreting data obtained from semi-structured interviews and content analysis of pertinent documents. The results of the study indicated that peer-to-peer activities, such as group discussions and collaborative projects, were highly valued by pre-service teachers as effective means for enhancing their collaborative learning and co-teaching skills. Furthermore, teacher education programs for prospective educators placed significant emphasis on inclusive pedagogy, which involves catering to the diverse needs of all students, and differentiated instruction, which enables teachers to modify their teaching approaches to better align with the learning preferences of their students. Prospective educators concurred that the act of observing and aiding experienced instructors in the classroom was advantageous for their individual professional growth and that they acquired knowledge and competencies in collaborative teaching as a consequence of these occasions

Reduction of Bridge Construction and Maintenance Costs through Coupled Geotechnical and Structural Design of Integral Abutment Bridges

Elimination expansion joints in the superstructure of integral abutment bridges offers the advantage of reducing the initial and life cycle costs of the structure. However, such elimination may have an adverse effect on the displacement demand at the pile-abutment connection and on the earth pressures on the abutment wall due to the thermal expansion/contraction cycles of the bridge. These adverse effects have resulted in regulations that impose restrictions on the maximum length and skew angle of integral abutment bridges. This research consisted of a deep analysis of the problem by considering soil-structure interaction. The approach was multifaceted as it included experimental and numerical analysis. Upon calibration and verification of the constitutive model, it was used as part of a parametric analysis to provide recommendations for the design limits of integral abutment bridges. The analysis results showed that active state earth pressure is reached after the first contraction cycle. The displacement demand on piles is a function of the abutment wall displacement. Larger displacement demand of the pile at the acute corner when compared to the obtuse corner was observed during expansion and contraction cycles. The inflection point of the piles deformed shape was found to be at relatively shallow depth. Concrete shrinkage and sequence of loading affected significantly the displacement demand of the supporting piles, lower displacement demand of piles during the expansion cycle and larger displacement demand during contraction cycles. The analysis showed that a 500 ft bridge with 60° skew will provide acceptable long term performance

Aspects of the Ayyubids Patronage of Jerusalem 583 AH/ 1187 AD - 658 AH/ 1260 AD

This paper attempts light on the role of Waqf (=endowments) in reviving life in all its aspects in Jerusalem after its liberation from the Franks by Salah al-Din al-Ayyubi 583 AH / 1187 AD. The endowments made by the Ayyubids in Jerusalem played a major and prominent role in reviving life in the city from all sides which will be clarified by reviewing some of the endowment models in this paper. We will also review the attempts aimed at liberating the Holy City and its people from the hardship and difficult circumstances they went through during the Frankish occupation to turn into a city teeming with life again, where the endowments had a crucial role in the rise of the Holy City as a center of civilization radiation. It is recommended to preserve this holy city and take responsibility for our beloved Jerusalem

The Digital Learning of Disabled Students: Perceptions of Teachers in Public Schools

The purpose of this study was to determine the perceptions of public-school teachers about digital learning for disabled students. The study employed a descriptive-analytical approach, using a questionnaire tailored to accomplish the studys objectives, which was developed by the researchers. A total of 124 male (55) and female (69) public-school teachers in Irbids public schools were included in the study. The outcomes of the survey revealed that public school teachers had a positive attitude toward digital learning. They also discovered statistically significant variations in the samples answers due to the variables of gender (in favor of females) and age (in favor of the age range 40-less than 50)

Reviewing Social Life in Eastern Jordan through Burckhardts Tour in 1812 AD

Historical travel books are important and rich sources of information, as they describe the different aspects of life in a specific geographical area and within a specific time. One of these crucial travel books is Johann Ludwig Burckhardts Travels in Syria and the Holy Land. He recorded, through his travels in southern Syria, important details of life in the east of Jordan region at the beginning of the nineteenth century. He shed light on an important period in the history of the region, and succeeded, through the strength and accuracy of his observation, in covering rich information about social elements in the region, including values, customs, traditions, lifestyles, clothing, and food. The importance of this travel comes as a crucial source for the student of the history of East Jordan at the beginning of the nineteenth century. Indeed, it presents useful, varied, and rich information in a period characterized by scarcity of information and writings. One of the most important results of Burckhardt’s travel was the rediscovery of the Arab capital of the Nabataeans, Petra, in 1812 AD. The study also concluded that a large number of urban centers retained their names. Another important outcome of this study is that there is clear evidence that life returned to many previously deserted areas. The study also showed that the region did not witness any interest from the Ottomans in terms of education and culture since there was no mention of any school or newspaper in the region rather, the Ottomans focused only administratively on the southern region because of the pilgrimage route

Grouping and sponsoring centric green coverage model for Internet of Things

Recently, green computing has received significant attention for Internet of Things (IoT) environments due to the growing computing demands under tiny sensor enabled smart services. The related literature on green computing majorly focuses on a cover set approach that works efficiently for target coverage, but it is not applicable in case of area coverage. In this paper, we present a new variant of a cover set approach called a grouping and sponsoring aware IoT framework (GS-IoT) that is suitable for area coverage. We achieve non-overlapping coverage for an entire sensing region employing sectorial sensing. Non-overlapping coverage not only guarantees a sufficiently good coverage in case of large number of sensors deployed randomly, but also maximizes the life span of the whole network with appropriate scheduling of sensors. A deployment model for distribution of sensors is developed to ensure a minimum threshold density of sensors in the sensing region. In particular, a fast converging grouping (FCG) algorithm is developed to group sensors in order to ensure minimal overlapping. A sponsoring aware sectorial coverage (SSC) algorithm is developed to set off redundant sensors and to balance the overall network energy consumption. GS-IoT framework effectively combines both the algorithms for smart services. The simulation experimental results attest to the benefit of the proposed framework as compared to the state-of-the-art techniques in terms of various metrics for smart IoT environments including rate of overlapping, response time, coverage, active sensors, and life span of the overall network

The carrying angle: racial differences and relevance to inter-epicondylar distance of the humerus

The human carrying angle (CA) is a measure of the lateral deflection of the forearm from the arm. The importance of this angle emerges from its functional and clinical relevance. Previous studies have correlated this angle with different parameters including age, gender, and handedness. However, no reports have focused on race-dependent variations in CA or its relation to various components of the elbow joint. This study aimed to investigate the variations in CA with respect to race and inter-epicondylar distance (IED) of the humerus. The study included 457 Jordanian and 345 Malaysian volunteers with an age range of 18–21 years. All participants were right-hand dominant with no previous medical history in their upper limbs. Both CA and IED were measured by well-trained medical practitioners according to a well-established protocol. Regardless of race, CA was greater on the dominant side and in females. Furthermore, CA was significantly greater in Malaysian males compared to Jordanian males, and significantly smaller in Malaysian females compared to their Jordanian counterparts. Finally, CA significantly decreased with increasing IED in both races. This study supports effects of gender and handedness on the CA independent of race. However, CA also varies with race, and this variation is independent of age, gender, and handedness. The evaluation also revealed an inverse relationship between CA and IED. These findings indicate that multiple factors including race and IED should be considered during the examination and management of elbow fractures and epicondylar diseases

Analyzing CNN Based Behavioural Malware Detection Techniques on Cloud IaaS

Cloud Infrastructure as a Service (IaaS) is vulnerable to malware due to its exposure to external adversaries, making it a lucrative attack vector for malicious actors. A datacenter infected with malware can cause data loss and/or major disruptions to service for its users. This paper analyzes and compares various Convolutional Neural Networks (CNNs) for online detection of malware in cloud IaaS. The detection is performed based on behavioural data using process level performance metrics including cpu usage, memory usage, disk usage etc. We have used the state of the art DenseNets and ResNets in effectively detecting malware in online cloud system. CNN are designed to extract features from data gathered from a live malware running on a real cloud environment. Experiments are performed on OpenStack (a cloud IaaS software) testbed designed to replicate a typical 3-tier web architecture. Comparative analysis is performed for different metrics for different CNN models used in this research

Performance evaluation of parallel manipulators for milling application

This paper focuses on the performance evaluation of the parallel manipulators for milling of composite materials. For this application the most significant performance measurements, which denote the ability of the manipulator for the machining are defined. In this case, optimal synthesis task is solved as a multicriterion optimization problem with respect to the geometric, kinematic, kinetostatic, elastostostatic, dynamic properties. It is shown that stiffness is an important performance factor. Previous models operate with links approximation and calculate stiffness matrix in the neighborhood of initial point. This is a reason why a new way for stiffness matrix calculation is proposed. This method is illustrated in a concrete industrial problem
