Abstract: In today’s interconnected and hybrid work environment, global tech teams frequently face miscommunication, collaboration inefficiencies, and cultural misunderstandings—issues rooted not in technical ability, but in the absence of robust Cross-Cultural Competence (CCC). As artificial intelligence (AI) and immersive technologies evolve, new possibilities have emerged for delivering soft skills training through Virtual Reality (VR)-driven experiential simulations. This study evaluates the effectiveness of AI-powered VR simulations in developing CCC among early-career professionals working in multinational technology firms. Grounded in Kolb’s Experiential Learning Theory (ELT), Bennett’s Developmental Model of Intercultural Sensitivity (DMIS), and Bandura’s Social Cognitive Theory, this mixed-methods study investigates how AI-adaptive VR modules influence user progression along intercultural sensitivity stages. The simulations are designed to mimic high-stakes multicultural workplace scenarios—such as remote team conflict, hierarchical ambiguity, and cross-cultural negotiation—leveraging real-time emotional feedback and decision-based branching to personalize the learning journey.Participants from global tech companies underwent structured VR-based learning interventions (3+ ELT cycles) over a four-week period. Pre- and post-assessments using the Intercultural Development Inventory (IDI) and Employer-Validated Global Soft Skills Index (EGSSI) revealed statistically significant growth in CCC, especially in adaptation and empathy. Qualitative reflections and biometric engagement data also indicated higher immersion and emotional resonance compared to video- or lecture-based training. The study offers compelling evidence that AI-augmented, VR-enabled soft skills programs can bridge cultural divides more effectively than traditional methods. It positions immersive technology as not just a medium, but a transformative agent in global workforce development.

Abstract: This paper presents a comprehensive analysis of the drivers and constraints influencing the market penetration of air conditioning equipment in Nigeria, with specific implications for sustainable growth and energy policy. Situated within a tropical climate and experiencing rapid urbanization and a growing middle class, Nigeria presents a significant, yet underexploited, market for cooling technologies. The methodology employed a quantitative survey design, administering a structured questionnaire featuring a five-point Likert scale to a purposive sample of 50 stakeholders including manufacturers, distributors and end-users. Data were analyzed using descriptive statistics via SPSS version 28 to quantify prevalent perceptions and trends. The findings clearly delineate a market caught between potent drivers and severe constraints. Key drivers identified include rising urbanization and housing development, a growing middle class, awareness of health and comfort benefits. Government programs promoting energy efficiency were also viewed favorably, though their impact was noted to be limited by enforcement. Conversely, the analysis reveals formidable barriers to widespread penetration. The high upfront cost of equipment and installation emerged as the most significant constraint, severely limiting affordability. This is compounded by Nigeria’s notoriously unreliable and inadequate electricity supply which increases operational costs and diminishes the perceived ease of use. Furthermore, a heavy dependence on imported units exposes the market to price volatility and foreign exchange fluctuations, while weak enforcement of existing energy policies and regulations fails to create a conducive environment for sustainable market growth. The penetration of air conditioning in Nigeria is a double-edged sword, representing both a marker of economic development and a potential threat to energy security and environmental sustainability. The study concludes that achieving sustainable growth requires a multi-faceted approach that simultaneously leverages the identified drivers and systematically addresses the constraints. Recommendations are therefore geared towards integrated policy actions: encouraging local manufacturing to reduce costs and import dependency; implementing financial incentives for energy-efficient units; strengthening enforcement of energy efficiency standards; investing in grid stability and renewable energy integration and launching public awareness campaigns to educate consumers on sustainable cooling solutions. Ultimately, this research provides a critical evidence-based framework for policymakers and industry stakeholders to foster a sustainable, accessible and efficient air conditioning market that aligns with Nigeria’s broader economic development and climate goals.

Abstract: Banana (Musa sapientum.), a rich source of essential nutrients is a staple food crop in many tropical regions. In spite of its economic viability, its production is faced with numerous challenges including diseases and pests, which can significantly impact yields and quality. This study aimed to determine the bacterial organisms and the bacterial community structure associated with banana fruits using Illumina next generation sequencing (NGS) platform. Ripe and unripe banana fruits were sourced from Choba market in Obio-Akpor Local Government Area, Rivers State, Nigeria. Deoxyribonucleic acid (DNA) extraction was done using Laragen’s validated proprietary bacteria DNA extraction protocol. Polymerase chain reaction (PCR) amplification was performed to target the V4 region of the 16S rDNA gene using the conserved primers 515F and 806R. The most abundant phyla obtained from ripe and unripe banana were Proteobacteria (41.7%), Firmicutes (25.7%), Bacteroidetes (9.7%) and Actinobacteria (2.5%). The abundance of the predominant genera (Pseudomonas) was 41.7%. Other genera with relatively high abundance includes Bacteroides (25.94%) and Ruminococcus (9.94%). The result from this study shows that banana fruits are associated with beneficial and pathogenic organisms of human interest. Beneficial microorganisms such as Trabulsiella and Bacillus can be harnessed to promote plant growth and confer anti-fungal resistance in plants through biotechnology.

Abstract: Recently, the use of RF mixers has grown substantially. The Gilbert cell remains the de-facto core thanks to its high conversion gain, strong port-to-port isolation, and suppression of even-order distortion. Multi-tanh linearization implemented with multiple parallel differential transconductance stages offers excellent linearity but typically yields very low conversion gain. In contrast, current-bleeding improves both linearity and conversion gain by injecting additional bias current, at the cost of increased power consumption. Leveraging CMOS for its low cost, low static power, and compact area, we designed single-ended and differential low-noise amplifiers (LNAs) for WCDMA reception using the BSIM3v2 (Level-49) UMC 0.18-µm process in the Xcircuit open-source EDA tool. The designs prioritize high gain, low noise, good linearity, and input matching to a 50-ohm RF system.
