Attempts have been made to review and analyse existing literatures and theories of e-government and to develop a conceptual framework for evaluating factors influencing e-government implementing in both developing and developed countries. This is necessary to build trust amongst stakeholders, to encourage collaborative working, and to ensure that transparent and generally acceptable systems are in place. It is expected that the proposed conceptual model would be validated by researchers and academicians in future, since it would be relevant for analysing those wider social and economic factors that have an impact on e-government and other information and communication technologies （ICTs）.展开更多

According to this weighted access controlframework, a trustworthiness model for aceess request is also given. In this model, we give themeasure of trustworthiness factor to access request- by using some idea of uncertainty reasoning ofexpert system, present and prove the parallel propagation formula of request trustworthiness factoramong multiple policies, and get thefinal trustworthiness factor to decide whether authorizing. Inthis model, authorization decision is given according to the calculation of request trustworthinessfactor, which is more understandable, more suitable for real requirement and more powerfulforsecurity enhancement than traditional methods. Meanwhile the finer access control granularity isanother advantage.展开更多

Risk factors were determined by analyzing the epidemic data using the brainstorming method; the analytic hierarchy process was designed to weigh risk factors, and the integrated multicriteria analysis was used to evaluate the final result. The completed framework included the risk factor system, data standards for risk factors, weights of risk factors, and integrated assessment methods. This risk assessment framework can be used to quantitatively analyze the outbreak and spread of HPAI in China's Mainland.展开更多

It is also a reflector of child centred teaching practices, classroom quality and child outcomes. These relationships are influenced by many factors that are personal to teacher and child and are also related to the classroom environment. Positive teacher-child relationships develop warm and secure teacher-child bondings which are beneficial for the socioemotional and academic success of the child. Dependent and conflictual teacher-child relationships are stressful for teachers and have a negative outcome for the child. This paper explores the literature to recognise the factors affecting teacher-child relationships and have proposed a conceptual framework to understand these relationships in ethnically and socioeconomically diverse classrooms. Literature has tried to define these relationships according to the attachment theory or through bio-ecological model of development thus ignoring the role of culture as a major factor in formation of these relationships. This paper used Bourdiue’s theory of Capital, Field and Habitus and Contextual System Model of Pianta as theoretical framework and proposes Cultural Framework for teacher-child relationships.展开更多
