Assessing the status of library information systems security

This study proposes an instrument to assess the current information system security status in libraries. The instrument is based on a model named LISSAM (library information systems security assessment model), which comprises five components: technological security foundation, information security policy, procedures and control, administrative tools, methods, and awareness creation. The instrument was pilot-tested with 50 respondents responsible for information systems or information technology in their libraries. All components received Cronbach alpha scores of <0.60 and were found to be reliable and acceptable. Findings revealed that over 95% of libraries have a high level of technological implementation but 54% scored poorly on organizational measures, especially on the lack of security policies, procedures, and user training. High scores on technological implementation were found to be correlated to sufficient financial support and early information and computer technology adoption.

Evaluating Usability for Mobile Application: A MAUEM Approach

Many traditional usability metrics were purposely created for desktop computer applications and may not be directly applicable to mobile device applications. Usability metrics refer as means of measuring or evaluating the usability factors, attributes and related measurable criteria corresponding to usability attributes. The objectives of this paper were to evaluate the usability attributes and metrics of mobile device applications by using the unsupervised usability evaluation tool. Subjective and objective measurements were used to clarify the usability metrics collected in the log file which are generated by the unsupervised usability tool. The proposed Mobile Application Usability Evaluation Metrics (MAUEM) model can provides guidance on how and what to measure for each usability attribute which could lead to a complete usability evaluation for a mobile application.
