The development that leads to the Cloud Computing Business Framework

The Cloud Computing Business Framework (CCBF) is proposed to help organisations achieve good Cloud design, deployment, migration and services. There are four key areas to be addressed: (i) Classification; (ii) Organisational Sustainability Modelling (OSM); (iii) Service Portability and (iv) Linkage. Each area's focus is described, and we explain how each fits into the CCBF and work altogether. The process that leads the CCBF is supported by literature, case studies, where examples in each CCBF key area are used to illustrate its effectiveness and contributions to organisations adopting it. CCBF has been used in several organisations offering added values and positive impacts.     

IT incidents and business impacts: Validating a framework for continuity management in information systems

Information technology (IT) incidents that make data inaccessible may cause businesses to lose customers, reputation and market position. Previous studies on information management have identified data availability as a key priority, and the literature on disaster recovery and business continuity describes ways of preparing for and avoiding IT incidents. However, no frameworks for information system continuity management (ISCM) have yet been validated. This research draws on a framework for business continuity management, and extends it to the context of information systems. The framework is validated in a survey of IT managers and chief information officers in large private and public organisations operating in Finland. The results suggest that the embeddedness of continuity practices in an organisation has perceived business impacts whereas, in contradiction of previous theory, there is no such direct relation in the case of organisational alertness and preparedness. The theoretical contribution is to validate the ISCM framework statistically. On the practical level, social factors such as committed managers and employees are influential in decreasing negative business impacts. Further research on the embeddedness of continuity practices is called for.     

Does the Opportunity–Propensity Framework predict the early mathematics skills of low-income pre-kindergarten children?

Prior studies have shown that the variables described in the Opportunity–Propensity (O–P) Framework have successfully accounted for the mathematics and science achievement of students in grades 1–3 and 8–12. The two goals of the present study were to (1) determine whether the O–P Framework could also account for individual differences in the early mathematics skills of low-income, pre-kindergarten children and (2) determine whether latent variables constructed from measured variables would account for performance in the manner specified in the O–P model. The O–P Framework assumes that high achievement in mathematics is a function of three categories of factors: (a) antecedent factors, variables that operate early in a child’s life and explain the emergence of opportunities and propensities, (b) opportunity factors, variables that measure a child’s opportunity to learn mathematics content at home and school, and (c) propensity factors, variables that capture a child’s propensity for learning in terms of self-regulation, motivation, and prior cognitive skills. To test the fit of this model for low-income children during the year before they attend kindergarten, the authors conducted a secondary analysis of achievement and background data from the Early Childhood Longitudinal Study-Birth (ECLS-B) Cohort data set. Structural equation modeling indicated significant associations between the antecedent factor, opportunity factor, and propensity factor, and between the opportunity factor and pre-kindergarten mathematics achievement. The results confirmed the fit of the model and identified the kinds of learning experiences that could promote the acquisition of mathematics skills in low-income children and improve their readiness to learn in first grade and beyond.

无标度网络上的观点动力学研究

在现实生活中,观点更改与达成共识是社会行为动力学研究的一个重要方面,受到了不同领域研究者的关注。基于演化博弈论建立一致性观点模型,研究了个体学习能力对无标度网络上个体观点演化的影响。依照个体度值,网络中的个体被分为 A、B 两类,A 类表示参与者度值高且学习能力强,B 类则与之相反。仿真结果表明,个体学习能力对观点演化行为具有重要影响。当学习系数小于 0.001 时,参与者倾向于保持自己的观点,使整个网络的观点在有限时步中难以达到一致。当 A 类所占比例提高时,网络达到一致的时间缩短,但当A 类所占比例增加到 0.8~1 时,网络达到一致的时间几乎保持不变。

A framework for evaluating electronic commerce adoption in Iranian companies

In order to acquire the numerous advantages of electronic commerce, issue of evaluating electronic commerce adoption has its own importance. For this purpose, based on the scientific research and literature reviews, technical, organizational and inter-organizational are identified as the three dimensions for evaluating electronic commerce adoption of the companies. Thereafter, expert viewpoints were put forward about criteria and indicators in each of the above-mentioned dimensions. On the basis of identified indicators and criteria, a framework was developed for evaluating the electronic commerce adoption in Iranian companies. Furthermore in this research, the framework is tested in 27 Iranian companies. The result indicates that there is a significant positive relationship between degree of electronic commerce adoption and stages of electronic commerce development in the companies. Based on the findings and test of the framework, it will present necessary guidelines for evaluating electronic commerce adoption.
