Models and Quality Control Charts for the Prediction of Compressive Cement Strength (Published)

This paper presents quality control charts techniques usually applied in quality control of compressive cement strength. Nonlinear regression model useful for the prediction of compressive cement strength at 28 days was proposed. Combining the prediction and quality control tools, a PI (Proportional Integral) controller useful for the regulation of 28 days compressive cement strength around a target (39 Mpa) was constructed. Results of the one-year prediction of quarterly compressive cement strength aligned with the values of the historical data obtained from a leading Cement Company in Nigeria for the years, 2011-2015.

Nagi Methods of Map Quality Evaluation (Published)

Map quality evaluation is one of the important tasks that can face map specialists in particular and map users in general. Numerical description of the map product to justify its quality was studied by the author who has developed before, a new approach of map quality evaluation that, successfully applied globally by different researchers. Here, in this research work, a new formula has been developed to numerically evaluate map product. The evaluation base on computing a satisfaction factor suggested to be called Weighted Nagi Factor. The developed formula assumes different weights of the map criteria according to map application or specification adopted. This new Weighted Nagi Method, successfully applied to a sample map product of Khartoum state survey authority. Results proved that the new weighted method is practicable to numerically describe a map product taking into account the importance of each criteria adopted according to a particular application. The method is also simple and easy to be applied by any stakeholder, map quality evaluator or map user.

Quality Control in Early Childhood Education (Published)

The growing demand and practice of early childhood education (ECE) within the Nigerian educational system have recourse for quality control and standardisation. This position has become necessary because of the proliferation of operators with the economic opportunity intentions. It is therefore a proposition that quality control in early childhood education should be ascertained in Nigeria within the policy framework. The prevailing situation of early childhood education in Nigeria and the prospects inherent for national development should be repositioned using strategic options that would ensure quality control. A mix strategy from the inputs of government, ECE operators, parents and critical stakeholders can be adopted to ascertain quality control in early childhood education.

Building Stakeholders’ Relations in Open and Distance Learning: The Quality Challenges at Play (Published)

Building stakeholders’ relations in ODL has the potential to release untapped potential and transfer of expertise through collaboration. However, there are some sticking challenges at play and this study examined these challenges to building stakeholder’ relations in ODL. This was a qualitative study. Information was collected through a survey of four regional campuses informed by a purposive sample of 284 students and sixty members of staff. Some very glaring challenges in the way of building stakeholders’ relations in ODL were unearthed. Suppressed voices working to scare away potential partners were seen as inhibitors and silent assassins of efforts to building stakeholders’ relations in ODL. There were far more damaging attitudes to ODL stakeholder relations than those that promote it. Some of the manifestations of these damaging attitudes were seen through the otherness of ODL institutions and their students, the low status accorded to ODL and the inherent belief that learning equals face-to-face teaching. The invisible hand of power from a close knit highly conservative old boys’ clique from conventional universities was visible in this study. The study concluded that ODL cannot therefore fulfil its purpose of building stakeholders’ relations without reference to these challenges some of which are inflicting shock and injury to the staff and students. The study thus, recommended a re-thinking on conditions building stakeholders’ relations in ODL considering that this issue is more than an academic argument about definitions of meaning. It is the question of who gets what from the paymaster’s limited pot and why (Doherty, 2008).

Minimum Standards and Accountability in Colleges of Education in Nigeria (Published)

This paper discussed issues of minimum standards and accountability in colleges of education system in Nigeria. Minimum standards in education system have been a critical issue since 1970 after the government take-over of schools from voluntary agencies. The issue needs to be addressed include: proliferation of educational institutions, varied mode of instructional delivery, non-observation of admission policy, increased examination malpractices, frequent strike actions and other disruptions that water down standards in education. These necessitated the researchers to examine the existing Minimum Standard in colleges of Education in Nigeria for the purpose of instilling uniformity in the system. The study x-rayed accountability and the degree of excellence towards the achievement of the goals of the National Commission for Colleges of Education in Nigeria. The paper highlighted problems and prospects of the commission and how to improve standards through the Governing Council and Teacher Registration Council of Nigeria

International Standards As Corporate Governance Mechanisms And Credibility Gap In Jordan Financial Managers’ Point Of View (Published)

This study aimed to examine what financial managers think about auditors implementation in relation with corporate governance mechanisms and credibility gap, by using an inferential descriptive statistical analysis. Corporate governance has shown flaws; where part of it was done to the weakness of financial managers activism, and since auditing is a very important avenue of faithful representation (credibility gap) of financial statements, and since shareholders depend on auditors’ reports, this article utilized primary data by distributing a questionnaire to the financial managers in Jordanian industrial companies regestered in Amman Stock Exchange to study the effect of implementation. The paper focused on the affect and relationship of the auditors’ implementation of International Audit Standards and International Standards on Quality Control; on the credibility gap by using regression analysis, and the demographic factors by using one way anova. Results showed a positive relationship between auditors’ implementation of International Audit Standards on the credibility gap as well as to the International Standards on Quality Control, and results also showed that respondants elder than 45 years were more realizable of the credibility gap than the younger ones, as well as to the PhD degree holders and those above 15 years of experience.

Factors Affecting Value Addition in the Leather Industry in Kenya (Published)

The leather industry holds a significant position in the agricultural sub-sector in Kenya. The industry has a high potential to make products of high quality that can address socio economic problems, and create employment and wealth. The success of the industry depends on value addition, which unfortunately has been minimal, and most of Kenya’s exports have been in the form of unprocessed raw hides and skins. As a result, the industry has not realized its full potential. The objective of this study was to investigate factors affecting value addition in the leather industry in Kenya. Adopting a case study design, the study focused on the influence of capacity building, technology, finance and quality control on value addition. The study population consisted of both incubatees and graduate incubatees of Leather Development Centre in Kenya Industrial Research and Development Institute. The findings show that the industry is characterised by low capacity building, and unskilled employees take long to upgrade their skills on the job. The industry uses old technology, does not practice expeditious machine upgrade; and repairs and maintenance are quite slow. Further, the leather industry is inadequately financed, and quality is compromised because of unavailability of affordable chemical inputs. The study recommends that in order to increase value addition, manufacturers need to invest resources with a view to upgrading their human capital and technology. The different players in the industry should analyse weaknesses in the present national policy framework, and address the loopholes that exist.
