The Challenges of Project Management in Public Property Development Projects in the Niger Delta Region
No full textThe study examined the challenges of project management in public property development projects in Niger Delta Region of Nigeria. The study revealed twenty three challenges of project management that is often time been faced by property developers during the development of public project. The public sector is known for multiple layers of reporting line (Stakeholder structure) and this poses huge challenges and as such the study looked at these issues and how they can affect the development of public projects. The study adopted a pragmatic research philosophy with qualitative and quantitative research approach. Qualitative and quantitative data were collected using twelve (12Nr) semi-structured interview, and one hundred and thirty (130Nr) questionnaires. The data was analysed using descriptive analysis techniques with relative important index (RII) and transcribing of data. Further, the result of the study shows that there are twenty three challenges of project management, but that project delivery time, quality management and procurement management is the most critical challenges. The study recommends that a project management office should be established and occupied by a professional (estate surveyor and valuer) especially who is trained in the project management body of knowledge. It is believed that this paper in no small measure will assist government’s officials, project managers, builders, clients and other stakeholders in the public sector, in checkmating the challenges of project management and improving public project delivery
Impact of Leadership Behavior on Employee Performance during the Covid-19 Pandemic: A Study of Patobong Village Government, South Sulawesi Province, Indonesia
No full textThis study examines the impact of leadership behavior on employee performance during the COVID-19 pandemic in the Patobong Village Government, South Sulawesi Province, Indonesia. Using a quantitative research design, multiple regression analysis was conducted on data collected from 60 government employees through structured questionnaires. The findings indicate that leadership behavior explains only 22.8% of the variance in employee performance (R² = 0.228, p < 0.05), suggesting that other factors, such as organizational culture and economic conditions, may play a more significant role. The key leadership behaviors examined include motivation (β = 0.36, p < 0.05), clear communication (β = 0.29, p < 0.05), decision- making (β = 0.27, p < 0.05), and adaptability. The normality test results (p = 0.000) indicate a non-normal distribution, highlighting the need for future research to explore non-parametric methods. Additionally, this study emphasizes the importance of culturally embedded leadership, demonstrating how sipakainge (mutual reminding), sipakalebbi (mutual respect), and sipakatau (treating others with dignity) contribute to effective leadership practices in a village government context. Despite its contributions, this study is limited by a small sample size, reliance on self-reported data, and a weak explanatory power of the model. Future research should incorporate additional leadership variables, employ a larger sample, and expand the study scope to other regions. These findings provide valuable insights for public administration researchers and policymakers on adaptive leadership strategies in crisis management and decentralized governance in developing countries
Behavioural Influences on Investment Strategies: The Role of Emotions, Biases, and Market Dynamics
No full textThe study examines the impact of psychological biases overconfidence, loss aversion, and herding behaviour on investment decisions using a mixed-methods approach combining quantitative surveys and qualitative interviews. A sample of 500 investors, including retail and institutional participants, was analyzed to assess behavioural patterns, risk tolerance, and market dynamics. Quantitative analysis revealed that overconfidence positively influenced trading frequency, with highly confident investors executing up to 20 trades per month, exhibiting a risk profile of 8, and achieving annual returns of 12%. Loss aversion, however, demonstrated negative correlations with investment returns (-0.48) and risk tolerance (-0.56), leading to conservative strategies and suboptimal decision-making during downturns. Herding behaviour intensified during volatile and crisis periods, with herding intensity rising from 4 in stable markets to 9 during crises, affecting 80% of participants. Regression analysis confirmed that overconfidence was a positive predictor of returns (β = 0.45, p = 0.001) and risk-taking, while loss aversion had a negative effect (β = -0.38, p = 0.005). Herding behaviour influenced decision patterns (β = 0.25, p = 0.012), particularly in unstable markets. Qualitative findings provided deeper insights into emotional triggers and decision-making tendencies. This study highlights the need for financial literacy programs, behavioural training, and regulatory measures to address biases and improve rational decision-making. Future research can explore AI-driven decision tools to mitigate biases and enhance investment strategies
Principal as Authentic Leader on Teacher Trust in the K-12 Educational Context
No full textThis study aimed to determine the significant relationship between authentic leadership and teacher trust in public elementary schools. A descriptive-correlational research design was employed, involving a sample of 133 teachers from public elementary schools in Baganga District, Division of Davao Oriental. Standardized questionnaires were administered through face-to-face surveys. The data were analyzed using mean, standard deviation (SD), Pearson product-moment correlation, and multiple linear regression analyses. The findings revealed that authentic leadership practices among teachers were at very extensive levels, as well as their trust in their leadership. Correlation analysis indicated a significant relationship between authentic leadership and teacher trust. Furthermore, all the domains of authentic leadership were found to significantly influence teacher trust. It is recommended that school administrators continue to foster an authentic leadership style, emphasizing transparency, ethical behavior, and relational transparency to enhance teacher trust. Additionally, ongoing professional development for teachers on authentic leadership may support the creation of a positive and trusting school culture. Encouraging teachers to engage with leadership in building trust actively may further enhance collaboration and overall school effectiveness
The Impact of Tax Rates on the Profitability of Listed Oil and Gas Multinational Firms in Nigeria
No full textThis research work examines the tax rate and profitability of multinational firms in Nigeria using the Multinational Oil Firms in Nigeria. The study\u27s population comprises the top five multinational oil and gas firms listed in Nigeria, namely Shell, Chevron, ExxonMobil, AGIP, and Total. A census sampling method was adopted for this study. The data used are gathered from the published annual statement of accounts of the companies for a decade, covering the period from 2011 to 2020. The Autoregressive Distributed Lag (ARDL) model was utilized as the technique for data analysis. Based on the results of the study: (1) H01 Marginal Tax Rate (MTR) on the short run has a negative and non-significant effect on Return on assets (ROA) with a p-value of 0.3940, (2) H02 Effective Tax Rate (ETR) on the short run has a positive and non-significant effect on Return on assets (ROA) with a p-value of 0.5976, (3) On the long run according to the result of the study; Effective Tax rate (ETR) has a negative and significant effect. Therefore, the study recommends that the relevant tax authorities should formulate tax reforms that would result in low taxation return rates, especially the statutory tax rate, as it is observed that there are tax incidence rates on the profitability of multinational firms. Based on these findings, the study recommends that policymakers prioritize stable and predictable tax regimes to foster a conducive environment for investment and sustainable corporate growth in Nigeria
Antecedents of Status Quo Bias in EV Adoption: A Prospect Theory Perspective from a Systematic Review
No full textAims: This study aims to identify and synthesize the antecedents of Status Quo Bias (SQB) in consumer resistance to electric vehicle (EV) adoption through the theoretical lens of Prospect Theory. The objective is to explain how psychological and behavioral mechanisms shape consumer reluctance to shift from internal combustion engine vehicles (ICEVs) to EVs.
Study Design: A systematic literature review was conducted following PRISMA guidelines, with inclusion criteria requiring studies to be peer-reviewed, apply Prospect Theory, and focus on automotive or mobility-related consumer behavior.
Place and Duration of Study: The review was carried out at the Department of Industrial Management, University of Kelaniya, Sri Lanka, and the Scopus database was systematically searched between February and October 2025.
Methodology: A structured multi-phase process was followed, including database selection, keyword searches, inclusion and exclusion screening, and quality assessment. The Scopus database was used to identify peer-reviewed studies explicitly applying Prospect Theory to automotive consumer behavior. From an initial pool of 22,511 records, 37 relevant studies were selected for full-text review. Data was extracted and coded using thematic analysis to identify recurring constructs and behavioral factors related to SQB in EV adoption.
Results: Analysis of the included studies identified seven overarching behavioral themes: cognitive value distortions, perceived risk dynamics, framing influences, behavioral persistence, socio-cultural influences, institutional design factors, and cognitive decision burden. Findings demonstrate that psychological mechanisms such as loss aversion, reference dependence, and uncertainty avoidance strongly reinforce SQB and often outweigh technological or economic advantages of EVs.
Conclusion: The study extends the application of Prospect Theory into sustainable mobility research by highlighting SQB as a key psychological barrier to EV adoption. The findings emphasize the importance of framing strategies, risk mitigation, infrastructure reliability, and supportive policy design to reduce psychological resistance and accelerate EV transitions. The review is limited to English-language peer-reviewed studies, with most evidence originating from developed markets
Business Intelligence, Process Mining, and Lean Six Sigma for Sustainable Business Model Innovation: A Comprehensive Review
No full textThis comprehensive review synthesizes the expanding body of scholarship on how business intelligence (BI), process mining, and Lean Six Sigma (LSS) collectively enable sustainable business model innovation in modern organizations. Drawing from multidisciplinary literature across operations management, information systems, sustainability science, and industrial engineering, the study examines how BI provides the data architecture and analytical foundation for real-time visibility, how process mining operationalizes event-log–driven transparency for continuous process improvement, and how LSS offers structured methodologies for reducing waste and optimizing value streams. Using a thematic synthesis approach, the review identifies the integration mechanisms through which these three capabilities support environmental, social, and governance (ESG) objectives, accelerate digital transformation, and strengthen decision-making for sustainable value creation. Findings demonstrate that BI-driven analytics enhance sustainability reporting and performance measurement; process mining uncovers inefficiencies and compliance deviations critical to ESG outcomes; and LSS embeds disciplined, data-driven improvement cycles into organizational routines. The review concludes by outlining a conceptual integration framework, highlighting implementation challenges such as data quality, skills gaps, and technological fragmentation, and proposing a research agenda focused on unified BI–process mining–LSS architectures for next-generation sustainable business models
Testing the Weak Form Efficient Market Hypothesis: An Interpretive Study of Market Efficiency Via Literary Logic and Evidence
No full textThe Efficient Market Hypothesis (EMH) is among conventional finance\u27s most hotly contested topics. EMH theory was first put forth in 1965 by Eugene Fama; it holds that no investor can make excess profit without engaging in high-risk assets since the stock prices rapidly reflect all the information instantly. The idea of EMH has been challenged by many studies since it is not only the rationality of investors on which investors founded the judgements, but also other elements like individual and personal opinions, behaviour, and heuristics that affect their decisions. The core concept of EMH has been consistently disproved due to market anomalies, like bubbles, crashes, momentum, and calendar effects. This paper aims to investigate the validity of a weak form of efficient market hypothesis in the modern environment by extensively analysing empirical findings from several research projects. By examining foundational works supporting and contradicting the theory, this study aims to investigate the paradox: if markets are efficient, why do irrational events like bubbles and crashes exist? It is implied from our results that although Weak Form EMH is a good theoretical framework, it does not take into account behavioural biases, constraints to arbitrage, or changing market dynamics in the current situation
Evaluation of Ownership Structure Impacts on Internationalization: A Case Series
No full textThis study examines how ownership structure of a company influences the internationalisation strategies of firms in emerging markets, focusing on state-owned and private-owned enterprises across the manufacturing, technology, and finance sectors. Adopting a case study methodology, the research draws on agency theory and internationalisation theory to explore how different ownership structure shape firms’ risk preference and strategic expansion. While prior studies have overlooked the behavioural implications of ownership in emerging market multinationals, this study addresses that gap by offering firm-level insights. Findings reveal that state-owned enterprises (SOEs), constrained by government oversight, exhibit low risk tolerance and delay foreign investments to ensure policy compliance. In contrast, private-owned enterprises (POEs) tend to pursue growth-oriented strategies with higher risk preferences. Family-controlled POEs are conservative, often ignoring minority foreign investors\u27 diversification demands, though foreign ownership or professional management can boost their risk preferences; hybrid state-private models face internal conflicts, limiting strategy and risk-taking. The study contributes to international business literature by demonstrating that ownership structure is a critical determinant of firms’ global strategies. It emphasises the need for emerging market firms to balance ownership control with managerial expertise to achieve effective internationalisation
Integrity-driven Leadership and Work-life Balance Initiatives of Teachers in Public Elementary School
No full textThis study aimed to examine the significant relationship between integrity-driven leadership and work-life balance initiatives among public elementary school teachers in the Talomo West District, Division of Davao City. A descriptive-correlational research design was employed, with 138 teachers participating as respondents. Data were gathered using validated survey questionnaires and analyzed using mean, Pearson product-moment correlation, and multiple linear regression analysis. The findings revealed that both integrity-driven leadership and work-life balance initiatives were rated as highly evident among the respondents. Correlation analysis indicated a significant positive relationship between the two variables. Further, regression results showed that specific domains of integrity-driven leadership, particularly ethical behavior and consistency in decision-making, significantly influenced the implementation of work-life balance initiatives. These results highlight the role of principled leadership in promoting supportive work environments. It is recommended that school administrators strengthen leadership practices rooted in integrity to foster more sustainable and balanced working conditions for teachers
