This study aims to investigate the adherence to cyber ethics by undergraduates in public universities in Akwa Ibom state, Nigeria when using electronic information resources (EIRs).

Descriptive survey research design was used for this study. A total of 7,771 undergraduates of University of Uyo (UNIUYO) and Akwa Ibom State University (AKSU), Nigeria constitute the study population. The sampling technique used for the study is the multistage technique. A sampling fraction of 5% was used to arrive at a sample size of 389.

This study revealed that in UNIUYO, more than four-fifths of the undergraduates – 55 (84.6%) in science, 55 (82.1%) in engineering and 61 (81.3%) in education – noted that they used the internet on a daily basis, and in AKSU, almost all the respondents in science (50, 90.9%) and about four-fifths in engineering (45, 80.4%) observed that they also used the internet on a daily basis for academic work. Adherence to cyber ethics guidelines was high at UNIUYO in education (44.2) and science (43.0) and at AKSU in engineering (42.9) and science (44.7).

The use of EIRs in universities has brought enormous changes, especially on how information are accessed and used by undergraduates. As EIRs have become important component in university libraries and continuously used by undergraduates for academic work, there is the possibility that frequent accessibility and utilization could increase the chances of unethical usage. This study is therefore significant in taming the tide of abuse and misuse of e-information resources in universities.

The correlation between adherence to ethics guidelines and the use of EIRs was positively significant at both UNIUYO (r = 0.139*; df = 206; p < 0.05) and AKSU (r = 0.136*; df = 168; p < 0.05). A high level of adherence to cyber ethics by the undergraduates can be encouraged and maintained through the formulation of cyber ethics policy in the universities by academic librarians.

This paper aims to numerically investigate the impact of gas diffusion layer (GDL) anisotropic transport properties on the overall and local performance of polymer electrolyte fuel cells (PEFCs).

A three-dimensional numerical model of a polymer electrolyte fuel cell with a single straight channel has been developed to investigate the sensitivity of the fuel cell performance to the GDL anisotropic transport properties – gas permeability, diffusivity, thermal conductivity and electrical conductivity. Realistic experimentally estimated GDL transport properties were incorporated into the developed PEFC model, and a parametric study was performed to show the effect of these properties on fuel cell performance and the distribution of the key variables of current density and oxygen concentration within the cathode GDL.

The results showed that the anisotropy of the GDL must be captured to avoid overestimation/underestimation of the performance of the modelled fuel cell. The results also showed that the fuel cell performance and the distributions of current density and oxygen mass fraction within the cathode GDL are highly sensitive to the through-plane electrical conductivity of the GDL and, to a lesser extent, the through-plane diffusivity, and the thermal conductivity of the GDL. The fuel cell performance is almost insensitive to the gas permeability of the GDL.

This study improves the understanding of the importance of the GDL anisotropy in the modelling of fuel cells and provides useful insights on improving the efficiency of the fuel cells.

Realistic experimentally estimated GDL transport properties have been incorporated into the PEFC model for the first time, allowing for more accurate prediction of the PEFC performance.

Determines and analyses the constraints on the financing and management of basic education in Akwa Ibom State, Nigeria. A survey design, developed into 17 modules and administered as interview schedules, was used to collect the data from respondents. At all levels of basic education, there was inadequate funding for the provision of physical and instructional facilities. This affected the management of basic education because of poor morale of teaching personnel, declining enrolment of pupils and students, except women in adult education classes. Financial support was very disappointing. Recommends that local government areas, state government, NGOs and communities should complement the efforts of the Federal Government by contributing towards the development of basic education, especially at primary and adult levels.

The Niger Delta is a region in Nigeria endowed with enormous natural resources of which petroleum oil is the most exploited. This petroleum oil has been the engine of development in Nigeria since 1958, providing more than 90 percent of total exports (CBN, 1981) and over 80 percent of Federal Government revenue. Despite this, the Niger Delta people remain poor and underdeveloped. Youth restiveness and violence is the order of the day. As a product of two separate youth forums, this paper recommends good governance, youth impact assessments, youth inclusion in decision‐making, as well as capacity building as a way out of this discord.

Presents a summary of the proceedings of the 2007 National Conference/AGM of the Nigerian Library Association (NLA) held in Uyo, Akwa Ibom State.

Draws on the nine scholarly papers and speeches presented at the conference.

An appropriate curriculum should be designed for the training of librarians in Nigerian universities, as well as in the training of school library media specialists. Public‐Private Partnership (PPP) in library and information services should be encouraged; the use of ICT is beneficial to undergraduates; and consortium development in agricultural research institutes is also indispensable. The virtual library in Nigeria is also valuable, the challenges not withstanding, and library and information services to rural communities should also be encouraged.

An original paper that has great value for library and information practitioners, government and policy makers.

The purpose of this study is to compare students and instructors’ perspectives on students’ performance based on unified theory of acceptance and use of technology (UTAUT) framework. This study also aims to propose additional variables that might be used to extend the UTAUT model to make it more appropriate for the educational setting.

The study was carried out using a three-pronged methodology, namely, literature review, expert interviews and self-administered survey of 430 students and 55 information and communication technology (ICT) instructors from tertiary institutions in Akwa Ibom State, Nigeria. Validity analysis were conducted using IBM SPSS version 24 and two structural equation models were finally obtained using AMOS version 24.

This study finds UTAUT constructs including social influence, facilitating condition and voluntariness of use to have direct and significant impact on students’ performance from the students and the instructors’ perspective. The result of the instructors’ perspective shows that ICT use behaviour of students have direct and significant impact on students’ performance, but the students’ result shows an insignificant direct effect of use behaviour on students’ performance. From the students and the instructors’ perspective, gender, age and experience have statistically significantly direct impact on performance expectancy in this study. The result also shows that additional variables including ICT instructors’ characteristics, motivation and personal environment directly affect students’ performance from the students’ perspective, but the result of the instructors’ perspective shows that the influence of ICT instructors’ characteristics, motivation and personal environment does not directly and significantly affect students’ performance.

This study was limited to tertiary institutions in Akwa Ibom State, Nigeria. Consequently, the findings of this study are limited to Akwa Ibom State, Nigeria, and may not be generalised to cover other countries.

This research shows that the students and instructors have different views on variables that impact on students’ performance. This study finds empirical evidence to support the direct impact of use behaviour on students’ performance from the instructors’ perspective, while the students disagree but indicated an empirical evidence to show that instructors’ characteristics, environment and motivation contribute a greater impact on students’ performance. From the students and the instructors’ perspective, gender, age and experience have statistically significantly direct impact on performance expectancy in this study. This adds to the findings in the original UTAUT that indicated that performance expectancy is moderated by gender and age.

The introduction of mobile telecommunication services in Nigeria led to the development of base transceiver stations (BTS) across the country. Inadequate power supply from the national grid has led to massive use of diesel-fueled back-up generators (BUGs). The purpose of this paper is to attempt to quantify and inform relevant stakeholders about air quality implications of BTS BUGs.

Seven major telecommunication network operators were identified. Emission factor approach was used to estimate the quantity of important air pollutants such as NO_x, CO, SO₂, PM₁₀, PM_2.5, PAH and TVOC that are emitted from the use of the BUGs based on fuel consumption rate and generators’ capacity. Fuel-based emission inventory and emission factor from the United States Environmental Protection Agency AP-42 and National Pollution Inventory were used to estimate pollutants emission from diesel-powered generators used in the BTS sites and amount of diesel consumed. Land distribution and per capita dose of the estimated pollutants load were calculated.

The study showed that the deployment of BUGs will lead to increase emissions of these air pollutants. The states that are most affected are Lagos, Kano and Oyo, Katsina and Akwa Ibom states with respective total air pollutants contribution of 9,539.61, 9,445.34, 8,276.46, 7,805.14 and 7,220.70 tonnes/yr.

This study has estimated pollutant emissions from the use of diesel-fueled BUGs in mobile telecommunications BTS sites in Nigeria. The data obtained could assist in policy making.

Research efforts aiming to improve understanding of how various organisational relationships contribute to better food quality (FQ) in a constantly changing business environment are limited. This study examines the effects of supply chain (SC) organisations on the quality of food products across multi-tiered segments with dynamic business situations.

Guided by a conceptual research framework based on contingency theory and netchain analysis, moderation-based partial least squares structural equation modelling (PLS-SEM) was used to analyse multi-tiered data from 405 shrimpers and 238 women processors in Akwa-Ibom, Lagos and Ondo states in Nigeria.

The authors' findings show that unpredictable business environments such as market turbulence (MT), power asymmetry (PA) and distrust (DT) not only directly influence SC organisations but also moderate how organisational networks contribute to improved FQ. Further results reveal that closer vertical ties such as relational contracts are prerequisites for small-scale actors to guarantee improved FQ along multiple nodes of the food system.

This is the first study to examine, from a contingency and multi-tiered perspective, how small-scale actors can maintain FQ across interdependent nodes of a food chain in a developing country context and to explore the complex interplay between SC networks and the quality of highly perishable food products in unpredictable business environments. Relevant theoretical and policy implications are discussed.

The purpose of this paper is to evaluate the performance of polypropylene glycol (PPG), as a corrosion inhibitor for aluminium corrosion in 0.5 M H₂SO₄ solution at 303-333 K and the effect of addition of iodide ions on the corrosion inhibition efficacy of PPG.

The corrosion inhibition performance of PPG alone and on addition of iodide ions in the acid medium was evaluated using weight loss and electrochemical [electrochemical impedance spectroscopy (EIS), linear polarisation resistance (LPR) and potentiodynamic polarization (PDP)] methods as well as surface analysis approach at 303-333 K. The morphology of the corroding aluminium surface without and with the additives was visualised using scanning electron microscopy (SEM). The trend of inhibition efficiency with temperature was used to propose the mechanism of inhibition and type of adsorption.

Results obtained showed that PPG moderately retarded the corrosion of Al in 0.5 M H₂SO₄ solution. Addition of KI to PPG is found to synergistically improve the inhibitive ability of PPG. From the variation of inhibition efficiency, K_ads, and E_a, with rise in temperature, physisorption mechanism is proposed for the adsorption of PPG and PPG + KI onto the Al surface in 0.5 M H₂SO₄ solution. Polarisation results showed that PPG and PPG + KI acted as mixed type inhibitor. The adsorption of PPG and PPG + KI, respectively, onto the metal surface followed El-Awady et al. adsorption isotherm model. SEM and water contact angle analysis confirmed the adsorption of PPG and PPG + KI on Al surface.

The research is limited to aqueous acid environment in aerated condition, and all tests were performed under static conditions.

The use of PPG as corrosion inhibitor for Al corrosion in acidic medium were reported for the first time. The results suggest that iodide ions could be used to enhance corrosion protection ability of PPG which could find practical application in corrosion control in aqueous acidic environment. The data obtained would form part of database on the synergistic effect of iodide ions addition to polymer to control acid-induced corrosion of metal.

Valuation for compensation on land and buildings compulsorily acquired for public purposes is statutory. The Land Use Act (LUA) of 1978 now cited as Laws of the Federation of Nigeria, CAP l5 LFN 2007, stipulates the use of Depreciated Replacement Cost (DRC) Method in the valuation for compensation purposes for building and installation. The purpose of this paper is to criticize the application of the DRC technique in the valuation by acquiring authority as it does not arrive at fair market value and adequate compensation in Nigeria.

The method adopted for the study was a case study of real world valuation for compensation. Data used in the study were gathered mainly from government ministries and agencies responsible for land acquisition and compensation purposes. They included the Ministry of Lands and Housing, Land Use and Allocation Committee, and Ministry of Works and Transport. Market data on rental value, sales prices and other relevant data were collected from firms of professional that deal in real property.

The result of the study reveals that valuation by acquiring authority using DRC methods as prescribed by the LUA does not reflect market value and it is inadequate to put the claimants in the position they were before the acquisition. As such, most victims expressed dissatisfaction with the amount paid to them, which sometimes result to crisis, conflict and prolonged litigation, resulting in delay in executing or abandonment of the intended project.

The study is limited to only one case study on acquisition and compensation for land and buildings with particular reference to Akwa Ibom State. This limitation does not invalidate the result as the law is applicable to the whole country.

The implication is that the LUA needs to be review to fair market value as basis of valuation and payment for site value as well as the constitution to add “adequate” to Section 44 (1a). This will reduce the incidence of many communities and land owners protest against the decision of government or its agents to acquire their land for public purposes.

The methodology meets the requirement of the law regarding compulsory land acquisition and compensation in Nigeria: The LUA of 1978. Using three scenarios: the valuation by acquiring authority, claimant’s valuers and independent valuers to illustrate the critique of the methodology, the result shows the inadequacy of compensation.
