Information and communication technology (ICT) has fundamentally transformed business transactions. While its uses have become ubiquitous in the advanced economies, emerging and developing economies are still struggling with the mode and manner of the deployment of ICT for business. Thus, this study seeks to investigate how small-and medium-sized enterprises (SMEs) utilize ICT in Nigeria for business internationalization. To achieve the goal of the study, a mixed-method was employed.A questionnaire was administered to 265 people consisting of SMEs staff, managers, and owners. Similarly, interviews were conducted with seven SME decision makers.Findings revealed that Nigerian SMEs used ICT tools, such as websites and social media platforms, for internationalization. The findings also revealed that the challenges of ICT did not affect its application by these SMEs, which contrasts with many previous studies. Furthermore, this study identified privacy concerns, internet problems, cyber insecurity, trust, and system anxiety as new challenges facing the application of ICT tools by SMEs. Similarly, the findings showed that lack of ICT competence and strategic focus of ICT applications are internal problems facing Nigerian SMEs.These findings provide insight for practitioners and academia on the internationalization of Nigeria SMEs and the application of ICT to promote business growth.
In this paper, we proposed a novel triple algorithm based on RSA (Rivest-Shamir-Adleman), AES (Advanced Encryption Standard), and TwoFish in order to further improve the security of Bluetooth that is currently using only 128-bit AES for encryption in its latest versions (Bluetooth 4.0-5.0). Furthermore, older Bluetooth 1.0A-3.0 + HS (High-Speed) devices use E0 stream cipher for encryption that has been shown to be weak by numerous researchers and thus it could be considered insufficient for high security purposes nowadays. In our novel approach, the triple protection of AES, RSA, and TWOFISH would enhance the level of security, which shields the data transmission in the Bluetooth. As the first step of our novel approach, we first encrypted the message by using AES with 128-bit key and then further encrypted it by using Twofish with the same 128-bit key. Finally, the 128-bit key generated in the beginning will be encrypted by using RSA with 1024-bit key to protect its over-the-air transfer. In the receiving end, the decryption process goes in reverse order compared with encryption process. We showed with experimental figures that our novel algorithm improved the security of Bluetooth encryption by eliminating all known weaknesses and thus made data exchange between Bluetooth devices secure.
Different personality traits respond differently to unfavourable life situations. Unemployment can have several negative social, economic, and domestic consequences. Many people use social media for a variety of reasons. The aim of this study is to examine the way different personality traits respond to Facebook in the period of unemployment. Data was obtained from 3,002 unemployed respondents in Nigeria. The study used regression model to analyse the data. Among the five personality traits, results indicated that the relationship between neuroticism and online social support was negative. However, the relationship between online social support and satisfaction was positive. The study highlights several theoretical and practical implications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
