    The system of competency assessment has a special importance in public employment because it is one of the tools that are used to assess the capability of the employees and their ability to satisfy their public duties, as well as their roles to achieve the goals of the administrative department in managing the public facility and attaining the public interest. The system of competency assessment seeks to achieve many objectives, the most important of which are: the advancement of the service that the public facility is providing, the improvement of the programs and methods of appointing employees and their training; the detection of the administration\u27s errors and problems; and the improvement of the competency of employees. This study will include the legal organization of the competency assessment in Kuwaiti civil service law, by identifying the public employees who are subject to this system and those who are making it. In addition, this study will shed the light on the assessment process, factors, and hierarchy. The time of assessment, steps, publicity, and effects will be covered in this study. Finally, the complaint about the competency assessment and the judicial appeal will be subject to discussion in the stud

    U-turns have been considered among the most hazardous locations on highways. The maneuvering of the driver at these locations is quite complex and risky. The behavior of the driver when turning is governed by the gap acceptance concept. In this study, the driver’s gap acceptance behavior at U-turn median openings was studied. 4 U-turn median openings in Irbid City were investigated. Data was collected by video recording. Two models were developed in this study. The first model estimated the time gap accepted by the driver. The second model calculated the turning function, which was used to estimate the probability of accepting gaps. Results showed that male drivers tended to accept shorter gaps than female drivers. Also, younger drivers were more likely to accept shorter gaps than older ones. The waiting time was also found to affect the gap acceptance behavior of the drivers. Drivers tended to accept shorter gaps after longer waiting times

    AbstractA spectrophotometric flow-injection method has been devised for the determination of nanomole quantities of some oxidants i.e. iodate, periodate, permanganate and hydrogen peroxide. The method is based on the oxidation of iron(II) to iron(III) and the measurement of the absorbance of the red iron(III)–thiocyanate complex at 485nm. The optimal oxidation pH and the linearity ranges of the calibration curves have been investigated. The analytical aspects of the method including the statistical evaluation of the results are discussed. The analysis of some authentic samples showed an average percentage recovery of 99%

    Abstract: The purpose of this study was to identify some factors that affect the provision of transition services to students with multiple disabilities in their institutions. One hundred and fifty-three (153) teachers who worked with students with multiple disabilities in the Kingdom of Saudi Arabia responded to the survey that included two sections; the first section included demographic data of the sample while the second section included (26) items that present the factors affecting the provision of the transition services for those students. The results of the study showed that essential factors that affect the provision of transition services for these students were the weakness of the professional development programs in the field of transitional services, poor collaboration between community agencies, whether government or private institutions participate in providing these services, the weakness of competencies of transition services that provide preparation programs for special education teachers in Saudi universities and other factors. The results of this study did not show statistically significant differences between these factors according to the gender, academic qualification, and the number of years of experience, and training in transition services. Finally, the study provided several recommendations about providing transition services for these students. Keywords: Transition services, students with multiples disabilities, effective factor

    In this research, road pavement maintenance by contract in Jordan was investigated. For this purpose, a subjective procedure (the Present Serviceability Rating (PSR)) was used to evaluate pavement serviceability. Three major highways (Jarash-Amman highway, Naour-Dead Sea highway and Zarqa-Syrian borders highway) that were maintained by contract were selected. The developed data base included information on pavement characteristics, traffic type and volume and routine maintenance cost. The effect of maintenance cost on pavement serviceability was estimated by developing a statistical relationship between maintenance cost and pavement serviceability rating before and after maintenance. The results showed that the pavement serviceability of Jarash-Amman highway and Naour-Dead Sea highway was adversely affected after applying maintenance by contract. The pavement serviceability of Zarqa-Syrian borders highway was slightly improved after applying maintenance by contract, but the improvement was not up to expectations. It is believed that the reasons for such results are a combination of the contractor’s poor experience and qualification and the timing of maintenance where the pavement was left without maintenance until it reached fair or poor condition

    AbstractObjectivesThe hand is the most commonly fractured site in the body, as it represents 17–25% of all body fractures. The metacarpal bone of the small finger is the most commonly fractured hand bone. This study aimed to determine the epidemiology and frequency of various fractures of the hand and the distal forearm in adults with a view to identifying patients who required surgical treatment.MethodsThis retrospective review examined the medical records of all hand and distal forearm X-rays performed on adult patients who presented to the emergency room of King Abdul-Aziz Medical City from January 2010 to December 2011.ResultsIn this study, we reviewed 2993 X-rays of the hand and the distal forearm. One-third of these X-rays confirmed fractures (n = 948), and more than two-thirds of these fractures were recorded in male patients (n = 702). There was no major difference in the distribution of fractures between the left and right hand. Half of these fractures (n = 472) were found in the young age group (18–30 years). The study showed that the phalanges had the highest proportion of fractures (n = 362, 40%). Distal forearm fractures represented one-third of all registered fractures (n = 287). Almost half of the metacarpal fractures were found in the 5th metacarpal (n = 104), confirming that the 5th metacarpal bone is the most commonly fractured bone in the hand. One-fifth of all fractures were surgically managed (n = 190, 20%).ConclusionOne-third of the reviewed X-rays identified hand and distal forearm fractures. Both hands were affected equally. Patients in the young age group are more prone to have fractures, and phalanges had the highest proportion of fractures followed by the distal forearm
