作者： salih Alasad West University of timisoara

the aim of this paper is to investigate the relationship between principal＇s leadership styles in Bedouin secondary schools in south Israel and teacher＇s intrinsic and extrinsic motivation. the research relies on the theory of full range leadership model and intrinsic and extrinsic motivation. Design/methodology/approach^cluestionnaires assessing the variables of interest were completed by 306 teachers in 22 Bedouin secondary schools in Negev in south of Israel. As results of our study, hypothesis which expects a positive relationship between transformational leadership and intrinsic motivation, and hypothesis that expects a negative relationship between laissez-faire leadership and intrinsic motivation have been accepted. On the other hand, hypothesis that expects a positive relationship between transactional leadership and intrinsic motivation has been rejected also the hypothesis that expects a positive relationship between transformational leadership and extrinsic motivation, and the hypothesis that expects a negative relationship between laissez-faire leadership and extrinsic motivation have been accepted, while hypothesis that expects a positive relationship between transactional leadership and extrinsic motivation has been rejected.

BACKGROUND: Hypertriglyceridemia induces acute recurrent pancreatitis, but its role in the etiology of chronic pancreatitis(CP) is controversial. this study aimed to evaluate the clinical laboratory and radiological findings of 7 patients with CP due to type 1 hyperlipidemia compared to CP patients with other or undefined etiological ***: We retrospectively analyzed the clinical, laboratory and radiological findings of 7 CP patients with type 1 hyper lipidemia compared to CP patients without hypertriglyceridemia these 7 patients had multiple episodes of acute pancreatitis and had features of CP on abdominal Ct, endoscopic retrograde cholangiopancreatography and/or endoscopic ***: All CP patients were classified into two groups: a group with type 1 hyperlipidemia (n=7) and a group with other etiologies (n=58). the mean triglyceride level was 2323±894mg/dL in the first group. Age at the diagnosis of CP in the first group was significantly younger than that in the second group(16.5±5.9 vs 48.3±13.5, P<0.001). the number of episodes of acute pancreatitis in the first group was significantly higher than that in the second group (15.0±6.8 vs 4.0±4.6, P=0.011)the number of splenic vein thrombosis in the first group was significantly higher than that in the second group (4/7 vs 9/58P=0.025). Logistic regression analysis found that younger age was an independent predictor of CP due to hypertriglyceridemia(r=0.418, P=0.000).CONCLUSIONS: type 1 hyperlipidemia appears to be an etiological factor even for a minority of patients with CP. It manifests at a younger age, and the course of the disease might be severe.

Complex Maxwell’s Equations

Journal of Modern Physics 2023年第12期14卷 1662-1671页

作者： Mahgoub A. salih Department of Physics Faculty of Science and Arts in Al-Miznab Qassim University Al Miznab Saudi Arabia

Maxwell’s equations in electromagnetism can be categorized into three dis-tinct groups based on the electromagnetic source when employing quaterni-ons. Each group represents a self-contained system in which Maxwell’s equations are applied and validated concurrently, in contrast to the previous approach that did not account for this. It has been noted that the formulation of these Maxwell equations ultimately results in the formulation of Max-well’s equations utilizing the scalar function.

Principal Leadership Styles in Bedouin Secondary School in the Negev

引用

Chinese Business Review 2017年第3期16卷 150-158页

作者： salih Alasad WestUniversityoftimisoara TimisoaraRomania

the aim of the research is to explore leadership styles applied by the principals of the secondary schools in Negev in south of Israel, as viewed by the teachers and it’s aimed to find out whether factors such as settlement, school location, and gender of teacher may change principal leadership style in the secondary school in Negev. the research relies on the theory of full range leadership model. Design/methodology/approach questionnaires assessing the variables of interest were completed by 306 teachers in 22 Bedouin secondary schools in Negev. Statistical analysis that had been made to the data included mean, standard division, and t-test. the results of the research indicated that the teacher characteristic affected the principal leadership style. Principal changed his/her behavior according to the teacher characteristic. the principal in temporary settlements is more transformative than principal in permanent settlement. Bedouin principal also is more transactional with non-local teachers than with local teachers and he is less laissez-faire with female than males.

Keratoconus is a non-inflammatory disorder which is gradual in development;corneal thinning and ectatic protrusion characterizes it. Keratoconus prevalence varies between different regions depending on several factors that affecting its prevalence. there are risk factors for developing keratoconus such as demographic and environmental factors. It was suggested that eye rubbing was associated with the development of keratoconus. the main aim of this review was to summarize the literature data about keratoconus and to identify the role of eyerubbing in the aetiology of the disease. A number of 24 articles was reviewed through the Pub Med, Google Scholar and Research Gates. there are many keywords used such as keratoconus, aetiology of keratoconus, eye rubbing, keratoconus prevalence, keratoconus and eye rubbing correlation. We concluded that eye rubbing causes the thinning of keratocyte, and the degree of effect of eye rubbing depends on the period and force of performing eye rubbing. It is recommended to avoid eye rubbing to prevent keratoconus, this can be achieved by avoiding itching and treating dryness of the eye and avoiding wearing eye lenses.

作者： salih Alasad West University of timisoara Timisoara Romania

the purpose of this paper is to explore the Bedouin educational system from the leadership context and its relation with professional development and to test professional development impact on teachers＇ practice. the research relies on the theory of full range leadership model and professional development and teaching practice. Design/methodology/approach-the questionnaires assessing the variables of interest were completed by 306 teachers in 22 Bedouin high schools in the Negev in south of Israel, in addition to an interview with 10 principals. As results of the study, hypotheses which expect a positive relationship between transformational and transactional leadership and professional development have been rejected. On the other hand hypothesis that expects no relationship between laissez-faire leadership and professional development and hypothesis which expects a positive relationship between professional development and teachers practice have been accepted.

Space-Energy Duality Generalized 4-Index Einstein Field Equation

引用

International Journal of Astronomy and Astrophysics 2023年第4期13卷 281-297页

作者： Mahgoub A. salih Department of Physics Faculty of Science and Arts in Al-Miznab Qassim University Al Miznab Saudi Arabia

the introduction of a new concept of space-energy duality serves to extend the applicability of the Einstein field equation in the context of a 4-index framework. the utilization of the Weyl tensor enables the derivation of Einstein’s equations in the 4-index format. Additionally, a two-index field equation is presented, comprising a conventional Einstein field equation and a trace-free Einstein equation. Notably, the cosmological constant is associated with a novel concept that facilitates the encoding of space and energy information, thereby enabling the recognition of mutual interactions between space and energy in the presence of gravitational forces, as dictated by Einstein’s field equations (EFE) and trace-Free Einstein Equation (tFE).
