The Servant Leadership of Public-School Principals in Jerash Governorate from the Teachers\u27 Perspective

e aim of this study was to identify the degree of Servant Leadership of Public-School Principals in Jerash Governorate from the Teachers\u27 Perspective, and know the impact of variables (gender, academic qualification, and years of experience) in that degree. The study sample consisted of (421) teachers, they were chosen by simple random method. A descriptive survey approach was used. To accomplish the objectives of the study, a questionnaire was built, which consisted of (34) items divided into four fields. The results revealed that the degree of Servant Leadership of Public-School Principals in Jerash Governorate from the Teachers\u27 Perspective, was (high), The results, further, indicated that there were no significant statistical differences at (α=0.05) in teachers\u27 estimates of the degree of Servant Leadership practice by their principals due to (gender, academic qualification, years of experience) variables

Factor Structure of the Quality-of-Life Scale According to Scale Length

The study aimed at investigating the factorial structural of the quality-of-life scale among the members of the Jordanian community, and to detect the impact of the reduction of the items of the original 100-items quality of life scale using the multiple Matrix sampling, the sample of the study consisted 3600 an individual from the Jordanian community Who were randomly selected For collecting data, the quality of life scale was used, The validity and reliability of the tool was confirmed on an exploratory sample including 170 individuals. The value of the reliability coefficient measured as a whole was used the Cronbach Alpha reliability coefficient 0. 967. The results indicated that the scale has good psychometric properties, and the results of the confirmatory factor analysis showed the validity of the factorial structure of the modified suggestion (or Hypothetical) model and the existence of agree between the modified suggestion model with the data obtained. In order to verify the effect of reducing the items of the 100-items Quality of Life Scale, a multiple sampling matrix was used and the original scale was split into 9 split questionnaires from the original scale, and applying the original(or main) scale and split questionnaires to different sample sizes, the results of the confirmatory factor analysis using the AMOS software indicated that the tenth and fourth split questionnaires achieved the best Goodness of fit

Detonation driven shock wave interactions with perforated plates

The study of detonations and their interactions is vital for the understanding of the high-speed flow physics involved and the ultimate goal of controlling their detrimental effects. However, producing safe and repeatable detonations within the laboratory can be quite challenging, leading to the use of computational studies which ultimately require experimental data for their validation. The objective of this study is to examine the induced flow field from the interaction of a shock front and accompanying products of combustion, produced from the detonation taking place within a non-electrical tube lined with explosive material, with porous plates with varying porosities, 0.7–9.7%. State of the art high-speed schlieren photography alongside high-resolution pressure measurements is used to visualise the induced flow field and examine the attenuation effects which occur at different porosities. The detonation tube is placed at different distances from the plates' surface, 0–30 mm, and the pressure at the rear of the plate is recorded and compared. The results indicate that depending on the level of porosity and the Mach number of the precursor shock front secondary reflected and transmitted shock waves are formed through the coalescence of compression waves. With reduced porosity, the plates act almost as a solid surface, therefore the shock propagates faster along its surface

Identifying patterns of weight-related health behaviors among US adolescents, and associated risk of obesity

Little is known about the current complex pattern of weight-related health behaviors among adolescents in the US. The goal of this report was to develop and examine a comprehensive latent class analysis (LCA) model examining the prevalence of combined associations of physical activities sedentary behaviors, and eating behaviors with obesity among female and male US adolescents (n= 12,031). Four classes and five classes were identified for female and male adolescents, respectively. Among which, three were similar and were characterized as ‘Inactive/ Low screen time/ Poor eating habit’, ‘Inactive/ Moderately high screen time/ Poor eating habit’, and ‘Active/ Low screen time/ Poor eating habit'. Additionally, ‘Inactive/ Low screen time/Good eating habit’ was unique to female adolescents, while ‘Moderately active/ High screen time/ Good eating habit' and ‘Moderately active/ Low screen time/ Good eating habit' were unique to males. Furthermore, the proportion of normal weight, overweight, and obese in each class was examined across females and males. The results showed that male adolescents had a higher proportion of people being obese than female adolescents in each class. The findings from this report provided insights on the current health needs of US adolescents and implied that gender-specific intervention strategies were required to reduce the risk of obesity among adolescents.Statistic
