This paper sets out to focus on the utilization of the locally available raw material to develop an acceptable and high quality non‐alcoholic beverage in Nigeria.

Maize‐based non‐alcoholic beverages were produced from either plain maize powder or combinations of maize powder and mango or soybean flour. Plain and fruit or soy‐ fortified maize powders were analyzed using standard methods for chemical composition, while total solid, sediment height, pH, titratable acidity, storage stability and microbial load were determined on the formulated beverage products. Taste panel evaluation was conducted to evaluate the acceptability of the products.

While the protein, fat and ash contents of plain maize powder were 5.69, 5.95 and 0.35 per cent respectively, there was minimal enhancement with fruit addition. However, with 10 per cent soybean addition significant improvement over the unfortified sample in protein (14.62 per cent), fat (10.64 per cent) and ash (0.96 per cent) was obtained. Sediment height was found to be higher for beverage with sour water and least for soy‐fortified beverage. Titratable acidity of beverage samples was found to be 0.022, 0.018, 0.054 and 0.306 per cent (per cent lactic acid) for plain, fruit‐flavoured, soy‐fortified and soured beverages respectively. Variation in titratable acidity was observed depending on the product and storage condition. Sensory evaluation result for beverage prepared with sour water (0–100 per cent) revealed preference for soured beverage with 80 per cent sour water. Also, fruit‐flavoured sample ranked highest in preference followed closely by the plain beverage, while soy‐fortified sample was the least acceptable.

The paper has demonstrated the feasibility of developing acceptable beverage samples from sour water (a by‐product of Ogi usually regarded as waste) and combinations of either maize powder and mango or soybean flour.

The level of corruption in Nigeria is very high, and this has grossly reduced the desired confidence and trust in the nation’s political leaders and political institutions. It is even worse to the extent that many of its citizens, especially in the medical profession, lecturers and other specialties, are leaving the country altogether because they have already lost hope in the country called Nigeria. Therefore, the purpose of this study is to investigate how political trust in Nigeria is affected by perceived corruption and to ascertain how social media use functions in this relationship.

Because this study is quantitative in nature, a positivist research philosophy is being used. A cross-sectional research design was used in this study. 14.1 million voters in north-central Nigeria are the study’s population, and a sample size of 385 was determined through an online sample size calculator with a 2% margin of error and a 95% confidence interval. The population was divided into smaller units for the study, and samples were selected from each unit using multistage sampling and simple random sampling techniques. An online self-administered questionnaire was used through the various social media’s platforms because of the nature of the study’s population to collect data. To examine the gathered data, descriptive and inferential statistics were applied. While inferential statistics were used to test the hypotheses through partial least squares structural equation modeling, descriptive statistics were used to analyze the respondents’ demographic data via a frequency table.

This study’s findings showed that social media use mediates the relationship between perceived corruption and political trust in Nigeria and that perceived corruption positively and significantly affects political trust in Nigeria.

This study is not without its limitations. Therefore, the few limitations of the study range from the limited sample sample to the population of Nigeria. Also, using only the quantitative research method for the nature of this research is another major limitation of the study. And lastly, using one out of the six zones in Nigeria will make it difficult to generalize the findings of the study. However, it is then recommended that future researchers consider a larger population than the current study for proper coverage; the future study can also use both the quantitative and qualitative research methods.

The practical implications of understanding how social media shapes political trust among political leaders through the lens of perceived corruption in the Nigerian political system are dimensional and have implications for various stakeholders, including policymakers, political leaders, media professionals and the general public. First, for policymakers and political leaders, the findings offer insights into the importance of proactive and transparent communication on social media. Recognizing the impact of social media on shaping perceptions of corruption, political figures such as the office of the presidency, senators, governors and all other political office holders can leverage these platforms to engage people.

This study is innovative because it examines, through the lens of perceived corruption, how social media use influences political trust among political leaders. This approach provides a new look at the relationship between digital engagement and political attitudes.

Despite the huge financial resources associated with oil, Nigeria has consistently recorded poor growth performance. Therefore, this study aims to examine how corruption and oil rent influence Nigeria’s economic performance during the 1996–2021 period.

Various estimation techniques were used. These include the bootstrap autoregressive distributed lag (ARDL) bounds-testing, dynamic ordinary least squares (DOLS), the fully modified OLS (FMOLS) and the canonical cointegration regression (CCR) estimators and the Toda–Yamamoto causality.

The bounds testing results provide evidence of a cointegrating relationship between the variables. In addition, the results of the ARDL, DOLS, CCR and FMOLS estimators demonstrate that oil rent and corruption have a significant positive impact on growth. Further, the results indicate that human capital and financial development enhance economic growth, whereas domestic investment and unemployment rates slow down long-term growth. Additionally, the causality test results illustrate the presence of a one-way causality from oil rent to economic growth and a bi-directional causal relationship between corruption and economic growth.

Existing studies focused on the effects of either oil rent or corruption on growth in Nigeria. Little attention has been paid to the exploration of how the rent from oil and the pervasiveness of corruption contribute to the performance of the Nigerian economy. Based on the outcome of this study, strategies and policies geared towards reducing oil dependence and the pervasiveness of corruption, enhancing human capital and financial development and reducing unemployment are recommended.

This study aims to obtain stakeholder perceptions of secondary education quality in Sokoto State, Nigeria.

A qualitative research approach was used by conducting interviews. Data were purposively collected from a sample of 15 education stakeholders in Sokoto State, and analyzed to extract major themes using the NVivo software program.

The results of the interviews suggested that high-quality education is defined by the following seven dimensions that fell under a systems-based framework: the provision of adequate instructional materials, the provision of educational infrastructure, imparting the “right” knowledge, meeting education “yardsticks”, provision of teacher support and welfare, creating a conducive learning atmosphere and availability of high-quality teachers.

The research is confined to the Sokoto State only. Although the findings may be applicable to other states of the Nigerian federation, the qualitative research design limits generalization beyond the present data. The research has methodological limitations in that only a qualitative approach was used in obtaining and analyzing the data.

This study presents dimensions of, and a definition of, secondary education quality, as perceived by education stakeholders in Sokoto State, Nigeria. This systems-based definition could be useful to the government in re-designing its educational plans and ensuring quality in secondary education programs. Once fully applied in the educational system, issues of low-quality education and graduation of unprepared students can be addressed more systematically. The goal of admitting more competent school leavers into tertiary institutions could also be pursued actively. Other social challenges, such as juvenile delinquency, can likewise be addressed. The study draws attention of those responsible for education provision in Nigeria to look inward to focus on those dimensions that need prompt and urgent improvements so that education quality can be ensured for a better society.

This study provides a systems-based framework of educational quality to guide school improvement efforts in Nigerian secondary schools that reflect values of regional stakeholders. This study demonstrates an easy-to-apply method for deriving educational quality indicators with stakeholder involvement. The dimensions obtained are supported by theory and the literature discussed.

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.

Given the diversity which exists among various groups of consumers, the purpose of this paper is to explore students' consumption of non‐alcoholic beverages in Nigeria.

Three focus groups and 20 in‐depth interviews were conducted with students in three universities located in Lagos, Nigeria.

Initial findings indicate that these students' consumption of non‐alcoholic beverages is influenced in many ways. Nevertheless, the most striking of these influences are found to be convenience of purchase, along with availability, price, health concerns, and culture/social reasons.

The main contribution of the study lies in the relevance of segmentation, targeting, and positioning activities of business organisations in respect of marketing of non‐alcoholic beverages. Based on the findings, the empirical study will serve as a valuable input to marketers in their planning, analysis, and implementation of appropriate marketing strategies to students vis‐à‐vis the highlighted influences on their consumption of this category of food. It will thus serve as a tool for creating competitive advantage in this prevailing volatile business environment.

The purpose of the paper is to highlight the considerations and lessons learned from a re-layout project in an assembly area for productivity improvement. The case study took place in Bosch Rexroth Oil Control Nonantola (Italy) with satisfactory results. The paper suggests how to approach reorganization projects with focus on productivity improvements following defined targets.

After an analysis of the initial status, the authors examine several plausible layout alternatives: the main comparison criteria and their weights are defined. Then a scoring/measuring procedure follows for the criteria of each alternative, and the alternatives are compared using principal parameters analysis (PPA).

The paper lists common considerations and lessons learned in the re-layout process. Using the PPA, the authors validate the best solution for the company.

This paper shares a valuable experience that is general enough to be shared with many other assembly systems. A unique experience combining re-layout planning, MTM and use of PPA is shared with the readers.

This paper aims to focus on the implications of female participation in the board on the management of intellectual capital for improved firm performance, particularly in the Nigerian-banking sector. It uses the resource dependency theory to ascertain the link between female board participation, intellectual capital and performances.

The paper adopted longitudinal panel analysis to analyze data obtained from the annual reports of selected listed commercial banks in Nigeria. The random effect regression was adopted as the method of analysis. The decision was informed by conducting the Hausman test.

The results revealed that female board participation has insignificant influence on bank performances, whereas intellectual capital efficiencies positively contribute to bank performances. However, significant influences were exhibited upon the interactions of female board participation and components of intellectual capital efficiency on bank performances.

Because of the focus of the research work, which is centered on the banking sector of the Nigerian economy, the findings of the research may not be sufficiently suitable for other sectors of the country. This, however, leaves the coast for other researchers to extend research on intellectual capital and gender participation to other non-financial sectors and other countries.

The outcome implies that there is a need for increased female participation in the boardroom to harness optimal intellectual capital efficiencies for firm performance. It further confirmed that intellectual capital unlocks the hidden treasure of firms.

The paper identifies and fulfills a niche on the need to extend the frontier of knowledge on intellectual capital and gender equity.
