The effects of Internet use on university’s students:The effects of Internet use on university’s students:“A Study on a Sample of Jordanian University’s students "This survey aims to identify the most important effects of Internet use on Jordanian public and private universities’ students by monitoring and analyzing a set of indicators that show the quality of the effects on specific fields such as cultural, social, psychological, moral and political effects .To achieve these goals, the study attempts to answer the following questions:1. What are the effects of Internet’s use on students?2. What is the relationship between the effects and demographic variables such as gender, age, family size and academic level and specialization. The population of our study is four public and private Jordanian universities. The questionnaire was distributed to study population in various specialties in all colleges of the universities by using available sample . The sample of the study was 891students . The males sample was( 55.22%) while the females sample was (44.78%( The data were analyzed by using descriptive statistical and analytical statistical measures by using the Statistical Package for Social Sciences (SPSS). The study has discussed the types of the effects of the internet on our samples in the following fields: cognitive and scientific influences, social and recreational influences, psychological effects, value effects, political influences, negative effects.It is clear that the "effect fields" of the Internet use on university’s students have high internal consistency values.In the field of "negative effects" the stability values ranged between (0.782) and (0.883) , And for the field of "value effects" indicate appropriate stability values.The results showed that the mean field of the "effects of Internet use" for university’s students was achieved to a medium extent. The mean of this field (2.01) was of relative importance (67.0). The level of all fields as a whole was average. The mathematical mean ranged from 1.90 to 2.23. In the first place was the "cognitive and scientific influences" with a mean of (2.23) and a relative importance (74.33). The social and recreational influences ranked second with a mean of 2.06 and a relative importance of 68.67. Internet use is observed to be medium, with average (1.94) relative importance (64.67), Finally, the "value effects" came with a mean (1.90) with relative importance (63.33).The results also indicate that "global electronic sites " are in the first rank electronic sites to be visited by the students , followed by "Arab sites" while "local sites" came in last rank. It indicates that the majority of students have a particular site they visit frequently.
In this paper we estimate the coefficients and scale parameter in linear regression model depending on the residuals are of type 1 of extreme value distribution for the largest values . This can be regard as an improvement for the studies with the smallest values . We study two estimation methods ( OLS & MLE ) where we resort to Newton – Raphson (NR) and Fisher Scoring methods to get MLE estimate because the difficulty of using the usual approach with MLE . The relative efficiency criterion is considered beside to the statistical inference procedures for the extreme value regression model of type 1 for largest values . Confidence interval , hypothesis testing for both scale parameter and regression coefficients

Show Moreالوصف Mixed ligand complexes of Cu (II), Co (II) and Zn (II) with 2-((4-(1-(4-chlorophenylimino) ethyl) phenylimino) methyl) phenol (L) and histidine (His) have been prepared and diagnosed by ¹H and13 C NMR, FT-IR and electronic spectral data, thermal gravimetric, molar conductance and metal analysis measurements. The ligand (L) shows a bidentate nature and the coordination occurs through N and O atoms of imine group and phenol group respectively whereas (His) behave as tridentate ligand, coordinating through the-NH2 group and carboxylate oxygen group and N atoms of imidazole ring. The analytical studies for three complexes have shown octahedral structure. The anticancer activity was screened against human cancer cell such Follicular
... Show MoreThis work includes preparation of Az, Qz, and Tz derivatives from the reaction of Schiff base (Sb) derivative with anthranilic acid, chloroacetyl chloride, and sodium azide, as well as, the characterization via FT-IR, 1H-NMR, and 13CNMR. The anticorrosion inhibition of these compounds was studied and the measurements of carbon steel (CS) corrosion in sodium chloride solution 3.5% (blank) and inhibitor in solutions were calculated at a temperature range of 293-323 K by the technique of electrochemical polarization. In addition, some thermodynamic and kinetic activation parameters for inhibitor and blank solutions (Ea⋇, ΔH⋇, ΔS⋇, and ΔG⋇) were determined. The results showed high inhibition efficacy for all the prepared compounds,
... Show MoreThe intelligent buildings provided various incentives to get highly inefficient energy-saving caused by the non-stationary building environments. In the presence of such dynamic excitation with higher levels of nonlinearity and coupling effect of temperature and humidity, the HVAC system transitions from underdamped to overdamped indoor conditions. This led to the promotion of highly inefficient energy use and fluctuating indoor thermal comfort. To address these concerns, this study develops a novel framework based on deep clustering of lagrangian trajectories for multi-task learning (DCLTML) and adding a pre-cooling coil in the air handling unit (AHU) to alleviate a coupling issue. The proposed DCLTML exhibits great overall control and is
