Opis:
The objective of this paper is to examine the influence of poverty, unemployment and GDP on entrepreneurship. Time series data for 31 years was collected from various official sources for the analysis. Vector autoregressive (VAR) framework was adopted to systematically capture the rich dynamic of multiple time series. Other tests conducted were unit root test, Johansen and Juselius (1990) co-integration test, Granger causality and dynamic model analysis beyond the sample. It was found that poverty and GDP influence entrepreneurship negatively, while unemployment influences entrepreneurship positively. The paper reveals the presence of both opportunity and necessity driven entrepreneurs in the country. There is a need for the government to revisit the existing policy on micro, small and medium enterprises (MSMEs) to adequately address the problem of the poor and unemployed by availing them with the opportunity to engage in entrepreneurship. Future study should consider mitigating the effect of frequent entry and exit from entrepreneurship in their data to correctly predict the effect of entrepreneurship on the economy.

Islamic reform
Opis:
Abubakar Gumi (1922–1992) was one of the central personalities for the development of Islam in Northern Nigeria who devoted himself to work on the reform of the religion (tajdid). He was also very active in the issue of the political unity of Muslims. Gumi’s major religious goal was to eradicate all innovations (bid’a) and to purify the faith. The Sufi brotherhoods were in his eyes not only the agents of the bi’a, but also movements which blocked the unification of Muslims. On the basis of his anti-Sufi ideas, Abubakar Gumi was connected with other thinkers of the Islamic world, especially Sayyid Qutb, the most influential thinker of the Egyptian Muslim Brothers. Gumi’s concept of the reform was also deeply influenced by the Wahhabi ideology. The article is an attempt to present Gumi’s condemnation of the bid’a as it is reflected in his programmatic treatise Al-Aqida as-sahiha bi-muwafaqat al-shari’a (The Right Faith according to the prescriptions of the Shari’a). Some attention is also paid to Gumi’s educational efforts and his role as the leader of the most recent movement of tajdid among Muslims in Northern Nigeria.

Opis:
Plant is one of the major forms of life on earth. It can produce its own food but cannot move about. Plants have well organized structures. They are beautiful and they determine local climates and are used as live fences. They phytoremediate and cool our environment. They provide us with oxygen, medicines, fuel, timber, recreation, industrial products; preservatives, pesticides in addition to all the three necessities of life: food, clothing and shelter. They purify the air and water bodies. It is therefore impossible to talk about life without plants because of their importance to the balance of nature. However, people have altered and often degraded their environment, though it has been taking place so gradually that its effects have not been drastically felt. Despite the enormous benefits of plants to humanity, they are disappearing at alarming rates. The reasons for this loss are many and include many anthropogenic activities. It is therefore quite imperative to ensure their effective conservation. This paper summarizes available information about the direct and the indirect benefits of plants and suggests some important measures to ensure their posterity. I hope, by bringing this information together, people will appreciate our plants and be frugal in using them.

Opis:
A study was conducted in four selected local government areas of Sokoto state in the extreme North-western part of Nigeria to quantify Sclerocarya birrea fruits as feed supplement for ruminant animals. The areas were Kware, Wamakko, Bodinga and Rabah. A check list was used to obtain information from ten respondents from five districts in each local government area making a total of 200 respondents. Information collected includes tree availability, yield and uses. Data generated from the study were subjected to simple descriptive statistics and analysis of variance. Results obtained indicated that 48 % of the respondents reported the availability of S. birrea while 20 % indicated its scarcity. 43 % of the respondents reported the use of S. birrea as food and medicine for animal and man and 10 % reported its use as fuel and wood work. Kware local government had a significantly higher number of S. birrea trees compared to other locations (P<0.05). However, the yield obtainable was significantly higher in Bodinga and Rabah local government areas (P<0.05) compared to Kware and Wamakko. Results indicated that a total of 13,953; 10,377; 11,069 and 9,641 kg of S. birrea could be obtained from Kware, Bodinga, Rabah and Wammako Local Government areas annually. It was concluded that S. birrea is a potential feed supplement in the dry sub-humid zone of Nigeria.

This study assessed the artisanal fisher folk’s perception of the effects of variability in climatic factors on fish yield in Kainji Lake basin. The specific objectives were to: describe the socio-economic characteristics of the respondents; assess the artisanal fisher folk’s perception of the effects of variability in climatic factors on fish yield; and assess the influence of variability in climatic factors on fish yield. Both primary and secondary data was used for the study. Primary data was collected from 173 respondents using structured questionnaires while secondary data was obtained from the Power Holding Company of Nigeria and the National Institute of Freshwater Fisheries Research (NIFFR), all of them located in New Bussa, Niger State. Once collected, the data was analyzed based on descriptive and inferential statistics involving the use of multiple regression models. As shown by the results, 91.32% of respondents were male; many (75.14%) of them aged between 41 and 60. Most of them (90.18%) were married and had Quranic education (96.62%). 48.74% had a household composed of 6 to 10 members. The respondents perceived all the factors of climate variability (draught, change in the lake’s water levels, variations in the seasonal calendar, change in seasonal rainfall, Harmattan intensity and change in temperatures) as unfavorable developments (with small variations in the mean scores). As an exception, humidity and change in sunlight conditions were believed to be favorable aspects by the respondents. The implication is that all the variables except humidity and change in sunlight conditions will adversely affect the fish yield, as claimed by the respondents. As shown by the results of a multiple regression study of the influence of variability in climatic factors on fish yield, the temperature had a negative influence on fish yield, whereas water inflow had a positive effect. The study recommends that the local population should attend adult literacy classes and improve their formal education levels. The management of NIFFR and other higher authorities, such as the Ministry of Water Resources and the Ministry of Environment, that are vested with the responsibility of managing the water bodies, should be advised to stock the water bodies with fish species that are resistant to temperature. In turn, the artisanal fisher folk should be encouraged to improve on their management practices, especially as regards overfishing and the use of obnoxious fishing methods. Also, they should extend their livelihood to such areas as crop production, animal breeding, trading/commerce and services as alternative income diversification strategies to cushion the effect of declining fish yields as a result of climate change.

Opis:
An experiment was conducted at Usmanu Danfodiyo University Teaching and Research Farm Sokoto, Nigeria to determine the utilization of Scelocarya birrea kernel meal (SBKM) as protein supplement in the diet of Uda sheep. Sixteen intact male animals were used for the experiment. The animals were divided into four (4) treatment groups replicated five times. The animals were fed diets containing 0, 5, 10 and 15% Scelocarya birrea kernel meal (SBKM). Data generated from the study were subjected to analysis of variance (ANOVA). Where significant difference exists, least significant different (LSD) was used to separate the means. Results indicated that total feed intake increased with increased level of SBKM up to 5% inclusion level; thereafter, it declined (P<0.05). Average daily gain (ADG) decreased from 99.90g/day for treatment 2 (5% SBKM) to 59.5g/day for treatment 4 (15% SBKM) (P< 0.05). Digestibility of dry matter (DM), crude protein (CP), crude fibre (CF), Nitrogen free extract (NFE) and ether extract (EE) were higher for treatment 2 (5% SBKM) (P< 0.05). Cost of fed per kg live weight gain (N 553.33/kg was lower (P<0.05) for treatment 2 (5% SBKM) compared to other treatments. It was concluded that inclusion of SBKM in the diet of Uda sheep should not exceed 5%.

Opis:
In this study, a series of destructive and non-destructive tests were performed on sandstone samples subjected to wetting-drying cycles. A total of 25 Wet-Dry cycles were provided to investigate any significant change in the engineering properties of sandstones in terms of their porosity, permeability, water absorption, density, Q-factor, elastic modulus (E), and unconfined compressive strength (UCS). The overall reduction in the values of density, E, Q-factor, and UCS was noted as 3-4%, 42-71%, 34-62%, and 26-70% respectively. Whereas, the overall appreciation in the values of porosity, permeability, and water absorption was recorded as 24-50%, 31-64%, and 25-50% respectively. The bivariate analysis showed that the physical parameters had a strong relationship with one another and their Pearson’s correlation value (R) ranged from 0.87-0.99. In prediction modeling, Q-factor and E were regressed with the contemplated physical properties. The linear regression models did not provide satisfactory results due to their multicollinearity problem. Their VIF (variance inflation factor) value was found much greater than the threshold limit of 10. To overcome this problem, the cascade-forward neural network technique was used to develop significant prediction models. In the case of a neural network modeling, the goodness of fit between estimated and predicted values of the Q-factor (R2 = 0.86) and E (R2 = 0.91) was found much better than those calculated for the Q-factor (R2 = 0.30) and E (R2 = 0.36) in the regression analysis.
