Assessing the Dynamics of kilowatt per capita in Nigeria; Evidence from Non-Seasonal ARIMA modeling
No full textUsing data from 1990 to 2023, this study examines the suitability of a non-seasonal ARIMA (0,1,1) model with drift for short-term forecasting of Nigeria\u27s annual per-capita electricity consumption (kWh). ACF/PACF analysis was used to determine the model specification, which was ARIMA (0,1,1) with drift (μ = 1.6456). The mean of the first differences was subtracted to estimate the drift. A moving average coefficient (θ = -0.2246) was obtained by maximum likelihood estimation, and a Ljung–Box test (p = 0.2941) verified the model\u27s adequacy and showed no discernible residual autocorrelation. Per-capita electricity use is expected to rise gradually between 2024 and 2026, with prediction intervals increasing over time to reflect growing uncertainty. These findings imply that the parsimonious ARIMA (0,1,1) with drift is a useful and interpretable tool for policy and planning in situations with limited data since it accurately captures the central trend in Nigeria\u27s per-capita electricity consumption and offers trustworthy short-term forecasts

Examining gender inequality in Nigeria : a case study of women entrepreneurs in Ogun State
No full textBased on collected interview surveys with thirty female entrepreneurs in three local government areas of Ogun State in Nigeria, this thesis examines gender inequality in opportunities as experienced by women entrepreneurs. Data collected, analyzed, and interpreted indicates systemic discrimination and marginalization against women entrepreneurs, which drastically limit their entrepreneurial talents. In Ogun State, women entrepreneurs do not have same access as men entrepreneurs to education, training, and funding opportunities. Discrimination and the marginalization of women are prevalent in Nigeria. It manifests in the high-level bias experienced by women in their everyday lives as compared to men. Nigerian women are subjected to various forms of discrimination and marginalization in their everyday, which undermines their fundamental social, political, economic, and cultural rights. The significance of women entrepreneurs on the economic development of any nation cannot be underestimated. Women play a critical role in the social and economic development of any nation, particularly in the entrepreneurship sector. This is certainly the case in Nigeria, where women constitute a substantial portion of the population. This study demonstrates that Nigerian women entrepreneurs possess the capacity to become greater contributors to economic development and bring about the long expected social change. Yet, Nigerian women entrepreneurs continue to face severe obstacles that limits their full economic potential to further contribute to the well-being of their families, communities, and societies. As such, there is an urgent need to harness Nigerian women's potential in order to advance entrepreneurship among them. This requires empowering women by increasing education, training, and funding opportunities so they can create a vibrant business environment and bring about a positive socioeconomic change. This research study identifies practical solutions to ensure equality in accessing the various benefits and opportunities available to women entrepreneurs; that is, the study outlines ways to advance gender equality by stressing the importance of women's empowerment in the journey to gender equality.Includes bibliographical references (pages 112-129)."In partial fulfillment of the requirements for the degree of Master of Rural Development.
The effects of debt subsidies on corporate investment behavior
No full textThis paper argues that credit subsidies are ineffective in stimulating business investment in productive assets. Instead, they lead to an increase in corporate holdings of financial assets and real estate. For empirical verification, the investment patterns in a sample of 241 Korean corporations listed on the Korean Stock Exchange between 1984 and 1988 were examined. The authors found a significant positive relation between corporate speculative asset holding and access to subsidized loans. Their estimates indicate that without interest rate controls and other forms of subsidy, corporate holdings of speculative assets would have been one-seventh of observed levels. Moreover, most corporate real estate holdings appear to be unrelated to production activities. Little evidence is found that the Korean government's interest rate controls and credit allocation policy have accelerated expansion of corporate investment. If anything, the controls are partly to blame for the overheated Korean stock market during 1986-88.Economic Theory&Research,International Terrorism&Counterterrorism,Banks&Banking Reform,Environmental Economics&Policies,Municipal Financial Management

Item is restricted indefinitely.The state of knowledge of agricultural support systems provides few insights into: (a) differences in resource-poor farmers' information seeking behavior and (b) the examination of agricultural information sources as support systems that may differ in their influence on technology development, transfer, and utilization.To fill this research gap, a field survey involving 200 soybean producing farmers was conducted in Southwestern Nigeria. Various institutions involved in providing information on soybean technology were categorized into national government and research institutions (NGI), international research centers (IRC), international intergovernmental institutions (IIGI), and informal institutions (INF). The basic assumption was that farmers' information seeking behaviors differ, that antecedent characteristics influence farmers' use of the various information sources, and that the use of the information source influences the technical, economic and social elements of technology adoption.The findings indicated that: (a) differences existed in the farmers' information-seeking behavior, (b) the education level, year of initial adoption, and resource status tended to influence farmers' use of the various information sources, (c) gender was found to relate to the proportion of total land allocated to soybeans as a new crop, and (d) information sources varied in their pattern of influence on the different elements of adoption; for example, use of NGI + IIGI emerged as the only intervening variable which significantly explained the probability of adoption in relation to technical, economic, and social elements.Theoretically, this thesis supports the model of agricultural research and technology transfer that recognizes the dual role of information source as it influences technology adoption, and is in turn, influenced by farmers' antecedent characteristics. The findings also suggest that NGI-supported programs tend to facilitate efficacy of service. Based on the findings, it is recommended that Nigerian government policy on agriculture consider the mobilization of potential sectors of support to complement public efforts. This effort will create and stabilize conditions necessary to increase resource poor farmers' use of effective and efficient information sources.Restriction data tranferred 2014-07-01T11:24:24-05:00

TREATMENT OF OIL SPILLS WITH NATURAL SORBENTS: A REVIEW
No full textAbstract: One of the most available high-energy-density fuels is fossil oils. As a result, people from every corner of the globe have sought fossil oils. They are usually sourced away from internationally recognized sites. Therefore, long-distance transport is required during which oil leakages become a problem. Oil spills and chemical leaks occur regularly as oil production and marine traffic expand. The release of effluents from the oil and gas industry has posed a severe environmental problem as its disposal has not been effectively curbed. Resolutions have been made and are still being made to solve the problem. With this, works from several researchers have shown the feasibility and working progress of applying separation techniques to obtain valuable products from the effluents. One of the areas that have been majorly studied is the adsorption of oil using inorganic adsorbents. Noting that most of the inorganic adsorbents are expensive, the use of agricultural biomass as precursors for adsorbents is now being considered, as they are relatively cheaper means. This review reports the impact of oil spills on the environment and highlighted the remediation of oil spills with organic adsorbents.

No full textLittle of the literature on nutrition between 1960 and the 1980s included assessments of effective nutrition programs. In this important study, the author focuses on factors associated with successful nutrition programs in Africa. This report concentrates on summarizing the information received from a mail survey, telephone and personal interviews and in-depth case studies. Seven factors were mentioned repeatedly as important to the success of nutrition programs: (a) community participation; (b) program flexibility; (c) institutional structure; (d) recovery of recurrent costs; (e) multifaceted program activities; (f) well-trained and qualified staff; and (g) infrastructure. The author concludes that these findings are preliminary and require further validation.ICT Policy and Strategies,Housing&Human Habitats,Health Monitoring&Evaluation,Health Economics&Finance,Poverty Monitoring&Analysis
Effect of Selected Preservatives on Nutritional Indices of Phaseolus vulgaris (Kidney Beans) and Phaseolus lunatus (Lima Beans)
No full textAbstract: Background: The increasing necessity for all season food availability as well the importance of nutritional value being preserved properly have resulted in the use of both natural and artificial preservatives. This research aimed at evaluation of the effect of selected preservatives on the nutritive indices of Phaseolus vulgaris (Kidney Beans) and Phaseolus lunatus (Lima Beans).
Materials and methods: The P. vulgaris and P. Lunatus used for this research were obtained in sac bags. In accordance with the research protocol. The both beans seeds were prepared and sent for preliminary analysis in laboratory before storage with selected preservatives proceed. The selected preservatives were procured and prepared for the preservation purpose following the research guidelines. The beans seeds were divided into airtight vessels and label it group A to E which were preserved with selected preservatives, DDVP (sniper), birds eye pepper, Aluminum phosphide, the group D was mixed with ash respectively while the fifth (group E) served as control and were left untreated with any preservative. The beans mixed with preservative were left to stay for 6 months. Standard methods were used to assess the effect of the preservatives on the proximate constituents, mineral concentrations and amino acid contents respectively compared with the control which was not mixed with any of the preservatives.
Results: It was observed from the results that the groups preserved with sniper and wood ash had lowest and highest % moisture content in both beans respectively, the crude proteins of the aluminum phosphide preserved beans showed a non-significant improvement in it % composition compared with control, there was also a non-significant (p ≤ 0.05) increase seen in the crude protein of the preserved groups when compared with control. For the crude fibre compositions it is observed that sniper preserved showed a significantly high content, with wood ash preserved group having the lowest % when compared with control. For the carbohydrate all group preserved with the selected showed a statistically significant improvement with sniper preserved with highest value of compared with control. It was observed from the result also that pepper preserved group had a significantly higher Ca concentration of while highest phosphorus significant value was observed in pepper preserved group. The results showed that kidney beans and lima beans are rich in essential amino acids with Lysine showing the highest concentration among the essential amino acid with a value of 8.17 g for the pepper preserved and was noticed to be same across all the essential amino acids while wood ash preserved group show dis-improvement in amino acid concentration.
Conclusion: The observed improvements in some parameters showed that the chemical in some groups are more effective at some aspect while natural preservatives at some other points. Its effectiveness for a longer shelf life and stop or delay the growth of bacteria, suppress the reaction when food comes in contact with oxygen or heat, they also prevent the loss of some essential amino-acids and some vitamins enhance the food flavors and colors. The results of this study improvements in shelf life and nutritional values.

No full textCurculigo pilosa is traditionally used in herbal medicine. This study aims to provide information on the secondary metabolites present in C. pilosa rhizomes powder, considering the growing interest in ethnomedicines in recent times. The rhizomes of C. pilosa were purchased from markets around Ogere, Ogun State, Nigeria. They were authenticated by a botanist, after which the rhizomes were washed and extracted using ethanol. The phytochemical composition and metabolomic profiles of the ethanolic extracts of C. pilosa were determined using gas chromatographic-mass spectrometric (GC-MS) methods. The results showed that the ethanolic extracts of C. pilosa had higher concentrations of phenols (9.27 ± 0.55 mg GAE/g), alkaloids (6.22 ± 1.95 g/100g), flavonoids (0.66 ± 0.05 g/100g), and saponins (0.51 ± 0.02 g/100g), but lower concentrations of glycosides (0.06 ± 0.01 g/100g), steroids (0.20 ± 0.02 g/100g), and tannins (0.09 ± 0.01 g/100g). The twenty-one bioactive compounds found in the extract include tetraethyl silicate (C₈H₂₀O₄Si), benzene, 1,2-dimethoxy- (C₈H₁₀O₂), 5-dodecene, (Z)- (C₁₂H₂₄), 7-tetradecene, (E)- (C₁₄H₂₈), spirohexane-1-carboxylic acid, ethyl ester (C₉H₁₄O₂), 1-dodecanol, 2-octyl- (C₂₀H₄₂O), formaldehyde, methyl (2-propynyl) hydrazone (C₅H₈N₂), D-allose (C₆H₁₂O₆), cyclohexane, 1R-acetamido-2cis,4trans-bis(acetoxy)-3trans-azido- (C₁₂H₂₂N₄O₅), 5-octadecene, (E)- (C₁₈H₃₆), acetamide, 2-(4-hydroxy-3-methoxyphenyl)- (C₁₁H₁₅NO₃), cyclopentanol, 1-(1-methylene-2-propenyl)- (C₉H₁₄O), 1,9-tetradecadiene (C₁₄H₂₆), 9-eicosine, (E) (C₂₀H₄₀), hexadecyl propyl ether (C₁₉H₄₀O), 9-octadecene, (E)- (C₁₈H₃₆), linoleic acid ethyl ester (C₂₀H₃₄O), 2-methyl-Z,Z-3,13-octadecadienol (C₁₉H₃₆O), 3-octadecene, (E)- (C₁₈H₃₆), 3-heptadecenal (C₁₇H₃₂O), tricyclo[5.4.3.0(1,8)] tetradecan-6-one, and 4-ethenyl-3-hydroxy-2,4,7,14-tetramethyl (C₂₀H₃₂O₂). Some of the phytocompounds identified in this study are biologically important and exhibit antimicrobial, antioxidant, and anti-inflammatory properties, which may hold therapeutic potential for both animal and human health
Exploring young students’ attitude towards coding and its relationship with STEM career interest
No full textDATA AVAILABILITY :
The datasets presented in this study are not publicly available for privacy reasons. The data is available from the corresponding author on reasonable request.This paper presents findings of an investigation on students’ attitudes towards coding and its relationship with interest in STEM-related careers. A concurrent mixed-method research design involving a pre-intervention-intervention-post-intervention non-equivalent control group was adopted. A sample of 50 grade seven to nine South African students (21 male and 29 female) from Township schools in Johannesburg, South Africa, participated. Quantitative data was gathered using the elementary students’ coding attitude survey and STEM Career Interest survey, while qualitative data was collected through a focus group interview. Interview data was analysed using content analysis, and quantitative data was analysed using multiple correlation analysis and standardized regression coefficients (β). It was found that students’ attitude towards coding was generally positive. A number of correlations between students’ attitude and their STEM career interests were significant at p < .05. Results also revealed that students’ attitudes in terms of coding confidence, coding interest, the social value of coding and perceptions of coders were found to be significant predictors of their interest in a STEM occupation. Based on this, it is argued that encouraging a positive attitude toward coding in students and increasing their self-efficacy can reinforce STEM learning and increase students’ interest in STEM occupations.Open access funding provided by University of Johannesburg.https://link.springer.com/journal/10639hj2024Education Management and Policy StudiesSDG-04:Quality Educatio
