The Impact of Knowledge Management Success Factors on Electronic Business in Jordanian Telecom Companies

Abstract: The study aimed to identify the impact of knowledge management success factors represented (organizational culture, administrative leadership, organizational structure, information technology infrastructure, standards) on electronic business (electronic information, electronic communications, electronic work flow), and the study community included all employees in Jordanian telecom companies, where the three telecommunications companies (Umniah, Zain, Orange) agreed to participate in the study, and (240) questionnaires were distributed to employees in those companies, and (191) questionnaires were retrieved, of which (188) were valid questionnaires for analysis with an actual response amount of (78.3%), which is similar to the final study sample. The study used the descriptive analytical method, and assumed a positive impact of the factors of success of knowledge management on electronic business in Jordanian telecom companies. The results showed that there is an awareness of the factors of success of knowledge management among employees in Jordanian telecom companies, where the arithmetic averages for the organizational culture variables, information technology infrastructure and knowledge measures came within the level of high importance, and the variable of administrative leadership and the organizational structure variable came within the level of intermediate importance in the current study, as well all averages of e-business dimensions came within the high level of importance, as well as the overall e-business variable, in addition to that, the results indicated a positive impact of the factors of success of knowledge management on e-business in Jordanian telecom companies; as the variable of knowledge management success factors explained (65.7%) of the variance in e-business, and the results also indicated that the variable of information technology infrastructure was the most influencing electronic information, and the second ranked in the impact of organizational culture, while the variables of administrative leadership do not affect the organizational structure and measures of knowledge on electronic information, and the results also showed that the variable of the information technology infrastructure ranked first in the impact on electronic communications, followed by the effect of the variable of organizational culture, and then the organizational structure variable, while the administrative leadership and knowledge standards variables do not affect, finally it showed the results indicated that the variable of the IT infrastructure was the most influential in the electronic work flow, and came second in the organizational structure, and the organizational culture ranked third, and the fourth came the variable of administrative leadership, while the electronic work flow variable was not affected by knowledge measures. Based on the results, the study recommended the need to pay attention to the employees awareness of the importance of success factors Knowledge Management, given its impact on e-business, by maintaining the level of organizational culture, and constantly enhancing it, raising the level of awareness of managers and decision makers about the importance of knowledge management success factors and their impact on e-business, developing the capabilities of employees, and creating a special administrative unit, concerned with knowledge management and organization Its operations, in addition to adopting successful organizational structures that increase the level of knowledge, as well as the need to develop and promote electronic business in Jordanian telecom companies, by paying attention to the communication infrastructure, and providing modern electronic workflow systems, the study also recommended researchers to conduct other studies on management success factors Knowledge and e-business in other study societies and other organizational outputs

Factor structure of the General Health Questionnaire (GHQ-12) in subjects who had suffered from the 2004 Niigata-Chuetsu Earthquake in Japan: a community-based study

<p>Abstract</p> <p>Background</p> <p>Factor structure of the 12-item General Health Questionnaire (GHQ-12) was studied by a survey of subjects who had experienced the 2004 Niigata-Chuetsu earthquake (6.8 on the Richter scale) in Japan.</p> <p>Methods</p> <p>Psychological distress was measured at two years after the earthquake by using GHQ-12 in 2,107 subjects (99.0% response rate) who suffered the earthquake. GHQ-12 was scored by binary, chronic and Likert scoring method. Confirmatory factor analysis was used to reveal the factor structure of GHQ-12. Categorical regression analysis was performed to evaluate the relationships between various background factors and GHQ-12 scores.</p> <p>Results</p> <p>Confirmatory factor analysis revealed that the model consisting of the two factors and using chronic method gave the best goodness-of-fit among the various models for factor structure. Recovery in the scale for the factor 'social dysfunction' was remarkably impaired compared with that of the factor 'dysphoria'. Categorical regression analysis revealed that various factors, including advanced age, were associated with psychological distress. Advanced age affected the impaired recovery of factor 'social dysfunction' score as well as total GHQ score.</p> <p>Conclusion</p> <p>The two-factor structure of GHQ-12 was conserved between the survey at five month and that at two years after the earthquake. Impaired recovery in the ability to cope with daily problems in the subjects who had experienced the earthquake was remarkable even at two years after the earthquake.</p

Predictive model of biliocystic communication in liver hydatid cysts using classification and regression tree analysis

<p>Abstract</p> <p>Background</p> <p>Incidence of liver hydatid cyst (LHC) rupture ranged 15%-40% of all cases and most of them concern the bile duct tree. Patients with biliocystic communication (BCC) had specific clinic and therapeutic aspect. The purpose of this study was to determine witch patients with LHC may develop BCC using classification and regression tree (CART) analysis</p> <p>Methods</p> <p>A retrospective study of 672 patients with liver hydatid cyst treated at the surgery department "A" at Ibn Sina University Hospital, Rabat Morocco. Four-teen risk factors for BCC occurrence were entered into CART analysis to build an algorithm that can predict at the best way the occurrence of BCC.</p> <p>Results</p> <p><b>I</b>ncidence of BCC was 24.5%. Subgroups with high risk were patients with jaundice and thick pericyst risk at 73.2% and patients with thick pericyst, with no jaundice 36.5 years and younger with no past history of LHC risk at 40.5%. Our developed CART model has sensitivity at 39.6%, specificity at 93.3%, positive predictive value at 65.6%, a negative predictive value at 82.6% and accuracy of good classification at 80.1%. Discriminating ability of the model was good 82%.</p> <p>Conclusion</p> <p>we developed a simple classification tool to identify LHC patients with high risk BCC during a routine clinic visit (only on clinical history and examination followed by an ultrasonography). Predictive factors were based on pericyst aspect, jaundice, age, past history of liver hydatidosis and morphological Gharbi cyst aspect. We think that this classification can be useful with efficacy to direct patients at appropriated medical struct's.</p
