The effect of C2C cycle on the profitability of listed Nigerian conglomerate companies
No full textThis study examines the relationship between C2C cycle and firm profitability for
the Nigerian conglomerate sector. The study is undertaken based on the historical panel data
analysis. To achieve this objectivean ex-post facto research design was employed. Data were
generated from secondary sources, specifically, the annual reports and accounts of quoted
firms from 2003 to 2012. The population of the study comprises of six Conglomerate companies
listed on the Nigerian Stock Exchange. Descriptive statistics, Pearson correlation, as well as
fixed-effect and random-effect Generalised Least Square (GLS) regression techniques
alongside with Hausman Specification Test as the decision rules were utilised as tools of
analysis in the study. The findings establish that C2C cycle is positively related to the efficiency
of the listed Conglomerate Firms in Nigeria, though the relationship is statistically
insignificant. Management has to attempt to uphold cash operating cycle. Since, as showed in
this study the lengthier the C2C cycle, the higher gainful the businesses turn out to beimplying
that a long operating cycle is more appropriate and logical as it influence profitability
Ownership structure and going-concern of listed Nigerian financial institutions : the moderating effect of audit committee’s characteristics
No full textThis study investigates the moderating effect of the audit committee characteristics (size, independence and financial expertise) on the relationship between ownership structure and firm going-concern in the listed Nigerian financial institutions. Data were generated from databases of annual reports for the listed companies in the Nigerian Stock Exchange. This study covers a period of 2006 to 2015 using panel data analysis method. The study sample consists of 29 listed financial institutions. The study found that CEO, foreign and institutional ownerships positively influence the firm going-concern. However, executives, non-executives and block ownerships negatively influence the firm going-concern. Furthermore, it is found that audit committee size strengthens the influence of CEO, block and foreign ownership on the firm going-concern. Whereas, it weakens the influence of the executives and institutional ownership on the firm going-concern. However, it does not moderate the influence of non-executive
directors’ ownership on the firm going-concern. Moreover, audit committee independence strengthens the influences of executives, non-executives and institutions ownerships on the firm going-concern. Whereas, it weakens the influence of CEO and foreign ownership on the firm going-concern. However, it does not moderate the influence of block ownership on the firm going-concern. Furthermore, audit committee financial expertise weakens the influence of block ownership on the firm going-concern. However, it does not moderate the influence of CEO, executives, non-executives, foreign and institutional ownership on the firm going-concern. These results indicate that despite the company and allied matters Act and codes of corporate governance requirements, yet, shareholders doubt the ability of audit committee financial experts in improving firm going-concern in Nigeria. This is because basic financial knowledge is not sufficient enough to cope with the emerging financial markets challenges. This study recommends policymakers to set more professional qualifications for audit committee members for effective monitoring to improve firm going-concern
Fractional investigation of time derivatives airflow process in a rectangular building
No full textAbstract: The study investigates the fractional time derivatives of air flow process across vertical openings in rectangular building by Caputo sense. Governing equations of air flow are solved analytically by Laplace transform technique and method of undetermined coefficient to obtain the solutions in Laplace domain. The solutions are inverted from the Laplace domain back to the time domain by the Riemann-sum approximation approach. The influence of the different flow parameters such as fractional order , Prandtl number , effective thermal coefficient and discharge coefficient are plotted in graphs. In the course of investigation, it is found that the increase or decrease in fractional order between the interval of the temperature profile and velocity profile will increase or decrease while the volumetric air flow and mass transfer will only decrease as fractional order increase.

The effect of inventory turnover period on the profitability of listed nigerian conglomerate companies
No full textThis study analyses the association concerning inventory turnover management and Nigerian conglomerate firms' profitability. The study is used a historical panel data analysis. Data were generated from the yearly accounts of listed firms from 2007 to 2016. The population of the study consists of six conglomerate firms registered on the Nigerian Stock Exchange. Feasible generalized least square (FGLS) regression was utilized as tools of analysis in the study. The findings establish that inventory turnover management affects Nigerian conglomerate companies' profitability inversely associated to the profitability of the listed conglomerate firms in Nigeria. The study suggests that there must be regular stock-taking to determine eventually, the slothful stocks to dodge over venture in such stocks (if any). Furthermore, if there is no high demand for the goods the inventory needs to be reduce that are obsolescence. Management should also implement an extraordinary inventory management measures
Ownership structure and discretionary loss provisions: the moderating effect of audit committee independence
No full textThis study investigates the interactive effect of an independent audit committee on the relationship concerning ownership structure and discretionary loss provisions. The study utilizes 29 listed Nigerian financial institutions as a sample using data from 2006 to 2015. The results establish that audit committee independence negatively influences discretionary loss provisions. Furthermore, it is found that CEO, block and foreign ownership have a direct influence on discretionary loss provisions. Moreover, audit committee independence moderates these direct relationships negatively. While institutional ownership has a direct influence on discretionary loss provisions, similarly, audit committee independence moderates this direct relationship positively. Additionally, audit committee independence fails to moderate but has a direct influence on discretionary loss provisions. Conversely, audit committee independence fails to moderate the relationship between the executive and non-executive ownership with discretionary loss provisions. The study suggests that relevant authorities should impose laws to motivate firms to have more independent members in audit committee to reduce conflicts of interest between the executive and non-executive ownership over the audit committee members’ composition to protect the interests of other shareholders
Contingency constrained TCSC and DG coordination in an integrated transmission and distribution network: A multi-objective approach
No full textTransmission System Operators (TSO) deploy Flexible AC Transmission Systems (FACTS) for congestion management in order to meet technical and multilateral power supply transactions. These power commitments are however constrained by thermal, voltage and stability limitations. On the other hand, the campaign to de-carbonize the power supply framework as seen Distribution System Operators (DSO) accommodate an increased penetration of Distributed Generation (DG) within their distribution networks. However, prerogative of system operators for separate planning of FACTS and DG systems can worsen power system’s key performance indicators especially under huge load growth and severe contingencies. Therefore, this paper developed an approach for contingency constrained coordination of Thyristor Controlled Series Compensator (TCSC) and DG through a multi-level optimization, comprising of a hybrid real power flow index and particle swarm in the first level and a multi-objective variant of particle swarm optimization in the second level. The contingency constrained coordination aimed to improve Available Transfer Capability (ATC), power loss and voltage deviation. Two models of DG were coordinated with TCSC under normal and contingency cases. Results indicate that while ATC improvement for various transactions were achieved with TCSC, additional power losses incurred was further reduced with DG deployment in coordination with TCSC. Furthermore, the Pareto front, which establishes the correlation between objectives shows a diving parabola that is partly nonlinear. Also, the TCSC−DGPQ provide superior ATC and power losses compared with TCSC−DGPV. Again, under (N−1) contingencies, the TCSC−DGPQ provides improved ATC compared with other contingency cases under TCSC only
