Security considerations for the spiral development model

Security measures have been well established within the waterfall development life cycle model. However, more software projects are using the spiral development life cycle model. Software developers and project managers can easily forget about adapting security measures. The spiral model uses iterative steps that can create changes in each phase of software development process. This will challenge security to ensure the application has few flaws or vulnerabilities that could be exploited. Failure to impose the right security measures at each of these phases can open up vulnerabilities for hackers to exploit and prove costly in patching. This paper will explore areas where security can be engaged within each iteration step of the spiral development model. This way security can continue protection of the software product as it becomes ready for deployment. The paper will help organizations realize where to deploy security measures to reduce vulnerabilities in the software application.     

Providing access to electronic information resources in further education

This article aims to provide a baseline for future studies on the provision and support for the use of digital or electronic information services (EIS) in further education. The analysis presented is based on a multi‐level model of access, which encompasses access to and availability of information and communication technology (ICT) resources, access to and availability of EIS resources, and the third leg of staff skills and their development. The research was conducted within the third cycle of the JISC (Joint Information Services Committee) User Behaviour Monitoring and Evaluation Framework, in 2001/2002. Evidence was gathered from library and information service web sites and various stakeholders, including library and information service staff, academic staff and students to generate insights into the provision of access to EIS in further education. Sector‐wide funding initiatives have had a significant impact on ICT infrastructures, and these attract a positive response from students. EIS are represented on some library web sites but both web site development and EIS availability is very much less advanced than in higher education. Staff, however, lack sufficient dedicated access to ICT to be able to develop their own skills and use. There remains a low level of access to electronic information resources, with only limited access to these resources through library web sites. LIS managers face a number of challenges in enhancing this provision, including licensing arrangements, tight budgets that need to be spread across many discipline areas, and the absence of EIS designed specifically for the further education student. The other key challenge lies in the provision of time and opportunity for academic and LIS staff to develop their ICT and EIS skills, and, more generally in the further development of the role of Information and Learning Technology (ILT) Champions.     

Assessing Model Similarity in Structural Equation Modeling

Two models can be nonequivalent, but fit very similarly across a wide range of data sets. These near-equivalent models, like equivalent models, should be considered rival explanations for results of a study if they represent plausible explanations for the phenomenon of interest. Prior to conducting a study, researchers should evaluate plausible models that are alternatives to those hypothesized to evaluate whether they are near-equivalent or equivalent and, in so doing, address the adequacy of the study’s methodology. To assess the extent to which alternative models for a study are empirically distinguishable, we propose 5 indexes that quantify the degree of similarity in fit between 2 models across a specified universe of data sets. These indexes compare either the maximum likelihood fit function values or the residual covariance matrices of models. Illustrations are provided to support interpretations of these similarity indexes.
