Nexus between Economic Phenomena and Growth Rate of Fishery Sector in Nigeria

Time series data that spanned from 1981-2019 sourced from CBN, FAO, and UNCTAD data banks were used to determine the growth of fishery sector in Nigeria. The obtained data was analyzed using the two-step methodology of Engel and Granger, Granger causality, and the impulse response function. The result showed evidence of co-integration between fishery GDP growth rate and the economic phenomena. Also, the GDP growth rate of the sector is efficient as it established a long-run equilibrium but the slow pace at which it corrects the distortion in its equilibrium makes the state of the efficiency to be a weak one. Furthermore, the fishery’s GDP growth rate is affected by high inflationary trend, red-tapism, and poor credit utilization. Empirical evidences showed that unexpected local shocks on the economic phenomenon will have a transitory effect on FGDP growth rate, thus will die-out over time. It was observed that the effect of the internal mechanism on the growth rate is passive while the external system effect is active on the growth rate. Therefore, the study recommends the need for policy strengthening by the concerned stakeholders viz: tiding of inflationary trend, red-tapism, and ineffective credit utilization, thus enhancing the growth of the sector

Navigating Fish Food Insecurity by Simultaneous Household and Marketed Surplus-Led Productions in Kogi State of Nigeria

The study determined the factors influencing simultaneously household and marketed surplus-led fish production in Nigeria’s Kogi State using cross-sectional data collected from 105 fish farmers. The sample size was achieved using a multi-stage sampling technique and the collected data were elicited viz. structured questionnaire complemented with interview schedule. Both descriptive and inferential statistics were used to achieve the conceptualized objectives. Empirical evidence showed that marketed surplus-led fish production was affected by less risky non-farm incomes with high-income turnover and capital paucity. However, marketable surplus-led production was enhanced by enlarged income, readily available demand that matches the supply, and entrepreneurship zeal among the youthful population in the studied area. In view of the foregoing, the research recommends the need to strengthen the value chain of fish marketing so as to contain any challenge viz. market imperfection which in the long run will jeopardize market-orientation of fish farming which is nascent among most of the farmers in the studied area. In addition, there is a need to address gender inequality in order to arrest poverty vulnerability among women folk viz. budget gender mainstreaming so as to achieve growth and development which are pre-requisite for globalization.Keywords: Food security; Marketable surplus; Purpose; Fish farming; Kogi State; Nigeri

Factors Determining Choice of Conventional Labour Among Yam Producers in Benue State of Nigeria

The present research empirically determined the factors that influenced the choice of combined labour for efficient yam marketable surplus in Benue State of Nigeria. 2016 cropping season cross-sectional data elicited by structured questionnaire complemented with interview schedule from a total of 120 farmers chosen through a multi-stage sampling technique was used. The instruments used for data analysis were descriptive and inferential statistics. The empirical evidences showed that decision for choice of efficiently combined labour that is supplemented by paid labour for efficient yam marketable surplus was affected by low yam productivity and low income which largely owed to poor proceeds from product marketing. Gender stereotype due to culture and religious barriers affected women access and control to productive access, thus hinders women active involved in yam entrepreneurship as they cannot carter for paid labour. Thus, it can be inferred that utilization of combined labour was affected by poor yield, gender stereotype and poor economic capital. Therefore, for farmers to be able to harness combined labour efficiently for a good marketable surplus, thus a better wellbeing for farmers, farmers need technical guided on potential yield; provision of buffer stocks for a remunerative price normalization; and, breaking the jinx of gender inequality through tacit sensitization in the studied area

Cloud Computing Adoption: A Mapping Of Service Delivery And Deployment Models

The recent upward trend in adopting cloud computing by businesses worldwide reflects the captivating opportunity of cost effective computing brought by cloud computing to replace the traditional IT computing services model. However, the decision to adopt cloud computing is somewhat complex. This paper will review the literature of cloud computing service and deployment models with the aim to determine the relevant characteristics of both service delivery and deployment models. Then, the authors will develop a mapping between the two sets of characteristics of cloud computing models. The mapping will lead to the development of a decision-making framework for managing cloud-computing adoption

Price Transmission, Volatility and Discovery of Gram in Some Selected Markets in Rajathan State, India

Market integration in many agricultural commodities had been extensively studied for the insight it provides into the functioning of such markets, thus giving valuable information about the dynamics of market adjustment, and whether there exist market imperfection, which may justify government intervention. This study empirically investigated price transmission, volatility and discovery of gram across four wholesale gram markets, viz. Jaipur, Kishangarh, Chomu and Malpura in Rajasthan state of India using Johansen's multivariate cointegration approach, VECM, Granger causality tests, GARCH, EGARCH and ARIMA. Monthly wholesale gram price data spanning from January 2011 to December 2015 sourced from AGMARKNET were used. Multivariate cointegration showed that all the selected gram markets were cointegarted in the long-run, meaning long-run price association among these markets. The degree of market integration observed is consistent with the view that Rajasthan state gram markets are quite competitive; thus, provide little justification for extensive and costly government intervention designed to enhance market efficiency through improve competitiveness. Therefore, in order to sustain the present system of market integration, there is need to evolve mechanism that will generate market information and market intelligence which would serve as a platform for guiding farmers in marketing their produce

Evaluation of the Water Quality of River Kaduna, Nigeria Using Water Quality Index

Water is a natural resource of fundamental importance and supports all life forms. The study evaluated the water quality of River Kaduna using the Canadian Council of Ministers of the Environment (CCME) Water Quality Index. The study covered both raining and dry seasons in 10 sampling points. Water parameters analysed were turbidity, Zn, Pb, Cd, Cr, Cu, Mn, Fe, dissolved oxygen, electrical conductivity, pH, TDS and Ni using standard laboratory techniques. The data obtained were used to develop Water Quality Index (WQI) across the 10 sampling points and results showed that the water quality at Barnawa, Kudenda, Tudun Wada, Makera and Angwan Muazu are poor as their index values ranged between 31.8 – 42 while Kawo, Angwan Dosa, Malali, Kigo and Angwan Rimi are marginal as their index ranged between 45 – 61.3. The study concluded that the variety and level of contaminants in River Kaduna was related to the anthropogenic activities in the various parts of Kaduna Metropolis from where run-off and contaminants were received, hence, the water quality of River Kaduna is deteriorating. There is therefore the need for proper environmental education and discouragement in the use of toxic chemicals for farming so that pollution can be controlled at the source.&nbsp

Modification and Performance Evaluation of Active Solar Dryer for High Moisture Tomato Crop

In this study, two active solar cabinet dryers with capacity each to dry 10 kg of fresh vegetable were fabricated. The drying cabinet of the first dryer was fabricated using plywood and is refer to as unmodified dryer (UM) while the second dryer with white transparent glass and is refer to as modified dryer (MD). The performances of the two dryers in terms of total drying time, final moisture content obtained and preservation of nutritive values of the dried vegetable were investigated using tomato as sample. Ten kilogram of the sample were sliced to about 1cm and neatly arranged in the drying chamber for the drying process in a period of two days (8am-6pm). The results revealed that there was a reduction in total drying time of 2.5 hours, from 18 hours in UM to 15.5hours in MD which corresponds to reduction in moisture content (wet basis) from initial value of 92% to final moisture content of 12- 13.3%. The results further revealed that maximum drying rate of 6.9 kg/h was observed for UM dryer and 9.4 kg/h for MD both obtained within 8 hours of drying time.  The average temperature recorded in the MD was found more than the UM by about 13°C at 3.00pm. The efficiency of the MD in terms of reduction in total drying time was 13.89% higher than the UM. Proximate analysis result shows the composition of the dried tomato in the UM to be protein, 0.76%; lipids, 1.00%; vitamin E, 0.0083%; moisture content, 13.3%; ash, 0.60% and crude fiber, 1.80%. However, the composition of dried tomato in MD were protein, 0.69%; lipids, 0.90%; vitamin E, 0.0080%; moisture content, 12%; ash, 0.58% and crude fiber, 1.78%

Coherent states for polynomial su(1,1) algebra and a conditionally solvable system

In a previous paper [{\it J. Phys. A: Math. Theor.} {\bf 40} (2007) 11105], we constructed a class of coherent states for a polynomially deformed $su(2)$ algebra. In this paper, we first prepare the discrete representations of the nonlinearly deformed $su(1,1)$ algebra. Then we extend the previous procedure to construct a discrete class of coherent states for a polynomial su(1,1) algebra which contains the Barut-Girardello set and the Perelomov set of the SU(1,1) coherent states as special cases. We also construct coherent states for the cubic algebra related to the conditionally solvable radial oscillator problem.Comment: 2 figure

A Compact Solid State Detector for Small Angle Particle Tracking

MIDAS (MIcrostrip Detector Array System) is a compact silicon tracking telescope for charged particles emitted at small angles in intermediate energy photonuclear reactions. It was realized to increase the angular acceptance of the DAPHNE detector and used in an experimental program to check the Gerasimov-Drell-Hearn sum rule at the Mainz electron microtron, MAMI. MIDAS provides a trigger for charged hadrons, p/pi identification and particle tracking in the region 7 deg < theta < 16 deg. In this paper we present the main characteristics of MIDAS and its measured performances.Comment: 13 pages (9 figures). Submitted to NIM
