Studies on information seeking behaviour have shown that workers, especially professionals look for information in order to perform their work related activities. Because the legal profession is an information-intensive one, understanding the sources consulted by lawyers for their task performance is important for librarians as service providers in order to ensure effective and efficient service delivery. This study seeks to understand the sources that are consulted by lawyers for specific job-related tasks they perform. Data was gathered using questionnaires from a total of 64 lawyers in Kwara State, Nigeria. Findings show that the sources consulted by lawyers are related to the kind of tasks they perform. While human sources are mostly consulted for the performance of tasks involving interpersonal communications such as negotiations and settling disputes out of court, the advocacy task requires that they consult authorised sources such as legal publications and literatures. However, a generally low use of electronic sources (such as e-databases and e-journals) was observed among lawyers.

New credit cards containing Europay, MasterCard and Visa (EMV) chips for enhanced security, and for in-store purchases (rather than online purchases) have been adopted considerably in recent years. EMV supposedly protects the payment cards in such a way that the computer chips in a card referred to as chip-and-pin cards generate a unique one-time code each time the card is used.  The one-time code is designed such that if it is copied or stolen from the merchant system or from the system terminal, it cannot be useful for creating a counterfeit copy of that card or counterfeit chip of the transaction. However, in spite of this design, EMV technology is not entirely foolproof from failure. This paper dis-cusses the issues, failures and fraudulent cases associated with EMV Chip-And-Card technology. The work also evaluates people’s understanding of these issues and the consequential precautions they take to safeguard their information while using the EMV cards for transactions.

Purpose This study investigates the moderating effects of age, experience and educational qualification on the relationship between uncertainty and subjective task complexity among lawyers working in private law firms in Lagos State, Nigeria. Design/methodology/approach A survey method was adopted and data were gathered using questionnaires. The analysis was carried out based on partial least squares structural equation modelling using SmartPLS 2.0 M3 software. Findings Results showed that the effect of uncertainty on subjective task complexity is significantly moderated by age, educational attainment, experience of the lawyers under study. Research limitations/implications Although data were collected in the most populated state and commercial hub of Nigeria, generalisation based on findings may still need to be made with caution. Practical implications Attainment of higher educational qualification is highly important for lawyers even though the minimum requirement to practice as a lawyer is a degree. Lawyers with higher degrees (LLM and PhD) had less uncertainty and perceived their tasks to be less complex compared to their counterparts who had the first degree (LLB). Originality/value The demographic profile of professionals (age, education and experience) has proven to have an impact on their perception about task complexity as determined by uncertainty as found in this study.
