Building Information Modelling (BIM) is one of the most visible aspects of a deep and fundamental change that is rapidly transforming the global construction industry. It is the platform that brings about collaboration between project stakeholders and improvement of project outcomes. The growing worldwide adoption and implementation of BIM for its powerful data-based modeling, visualization, analysis and simulation capabilities represents a paradigm shift to an integrated digital information infrastructure that will ultimately revolutionize almost all aspects of the construction industry. Many developed economies of the world have recorded impressive outcomes by implementing BIM in their construction practices, and this necessitates the need for an investigation into the level of its awareness and factors affecting its adoption in the Nigerian Construction Industry. The study was undertaken through a survey of Nigerian Building construction firms. The central issues addressed were the awareness of the respondents on BIM, and their perception on the drivers and barriers to its adoption in the Nigerian construction industry. Structured questionnaires and semi-formal interviews were used for data collection. The study highlighted areas requiring attention by researchers, government and other stakeholders towards a country wide implementation of BIM technologies and has set a scene for developing a framework for BIM adoption in the Nigerian construction industry. This will make the industry equipped to operate in line with the global best practices and deliver projects successfully and more efficiently and also be a good market for foreign firms to benefit. BACKGROUND
Flonicamid is a chordotonal modulator and novel systemic insecticide that has been used frequently for controlling a broad range of insect pests. The risk of flonicamid resistance was assessed through laboratory selection and determining inheritance pattern and cross-resistance potential to five insecticides in house fly, Musca domestica L. Very low to high flonicamid resistance in M. domestica populations was found compared with the susceptible strain (SS). A flonicamid-selected (Flonica-RS) M. domestica strain developed 57.73-fold resistance to flonicamid screened for 20 generations compared with the SS. Overlapping 95% fiducial limits of LC50 of the F1 and F1ǂ, and dominance values (0.87 for F1 and 0.92 for F1ǂ) revealed an autosomal and incomplete dominant flonicamid resistance. The monogenic model of resistance inheritance suggested a polygenic flonicamid resistance. The Flonica-RS strain displayed negative cross-resistance between flonicamid and sulfoxaflor (0.10-fold) or clothianidin (0.50-fold), and very low cross-resistance between flonicamid and flubendiamide (4.71-fold), spinetoram (4.68-fold), or thiamethoxam (2.02-fold) in comparison with the field population. The estimated realized heritability (h2) value of flonicamid resistance was 0.02. With selection mortality 40–90%, the generations required for a 10-fold increase in LC50 of flonicamid were 94–258 at h2 (0.02) and slope (3.29). Flonicamid resistance was inherited as autosomal, incomplete dominant, and polygenic in the Flonica-RS. Negative or very low cross-resistance between flonicamid and sulfoxaflor, clothianidin, flubendiamide, spinetoram, and thiamethoxam means that these insecticides can be used as alternatives for controlling M. domestica. These data can be useful in devising the management for M. domestica.
Purpose The purpose of this study is to examine the contribution of academic and professional institutions in promoting the awareness and knowledge of Islamic banking and finance in Nigeria. Design/methodology/approach The data were generated through a documentary research method by examining the Benchmark Minimum Academic Standards (BMAS) for Nigerian universities and Nigerian university curricula for the relevant undergraduate programs, as well as examination syllabi and training brochures for the relevant professional associations. Findings The study found that universities do not promote significantly the awareness and knowledge of Islamic banking and finance. Similarly, the relevant professional associations through their examinations and training programs contribute little or nothing to the promotion of awareness and knowledge. Research limitations/implications This study solely relied upon documentary evidence upon which the findings were based. In addition, for academic institutions, only undergraduate BMAS and curricula were examined. Practical implications There should be collaborations between the National University Commission of Nigeria, relevant Islamic and non-Islamic professional bodies and Nigerian Universities to ensure that courses (subjects) that could promote the awareness and knowledge of Islamic banking and finance are fully integrated into academic and professional curricula and training programs. Social implications The integration of an adequate number of relevant courses/topics into academic curricula and professional institution examination syllabi and their Mandatory Continuing Professional Development programs would greatly contribute to the production of competent and skillful employees to work for the growth and development of the Islamic banking and finance industry. Originality/value This study provides better ways of ensuring that knowledgeable and qualified employees are produced to work for the sustainability of the global Islamic banking and finance industry.
