Evaluating the Impact of Critical Factors in Agile Continuous Delivery Process: A System Dynamics Approach

Continuous Delivery is aimed at the frequent delivery of good quality software in a speedy, reliable and efficient fashion – with strong emphasis on automation and team collaboration. However, even with this new paradigm, repeatability of project outcome is still not guaranteed: project performance varies due to the various interacting and inter-related factors in the Continuous Delivery 'system'. This paper presents results from the investigation of various factors, in particular agile practices, on the quality of the developed software in the Continuous Delivery process. Results show that customer involvement and the cognitive ability of the QA have the most significant individual effects on the quality of software in continuous delivery

Analysis of Asset Ownership and Labour Inputs among Farming Households in Ilaro Agricultural Zone, Ogun State

This study focused on analysis of asset ownership and labour inputs among farming households in Ilaro Agricultural Zone, Ogun State. Both primary and secondary data were used for the study. Data were collected through the use of structured questionnaires and oral interview. A total number of 80 farmers were sampled for the study. The respondents were selected by multistage sampling techniques. Descriptive analysis was used to analysis the socio- economic characteristics of the farmers in the study area. Multiple regression analysis was done to determine the effect of analysis of asset ownership and labour inputs among farming households. Also, stochastic frontier production function was used to access the effect of socio economic factors on asset ownership. The findings revealed that 33.8% of the respondents had formal education up to tertiary level and 85% had farming as their main occupation. The stochastic frontier analysis result revealed that increase in educational level, farm experience will decrease the technical inefficiency; and positive coefficient variables will also increase the technical efficiency of the asset ownership. Based on the finds of this study, the following recommendations were made: there is need to design a policy to ensure that farmers have good access to fertilizer through adequate supply and efficient distribution so as to increase productivities. This could be achieved through the expansion of domestic production and the development of rural infrastructure, especially rural roads that can facilitate accessibility at lower cost of the farmers. Also policy attention should also be directed towards providing labour saving technology to ease farm operation. Keywords: Asset, Ownership, Farm, Labour, Capita

High incidence of multidrug-resistant strains of methicill inresistant Staphylococcus aureus isolated from clinical samples in Benin-City, Nigeria

Infections of methicillin-resistant Staphylococcus aureus (MRSA) are becoming an increasingly concerning clinical problem. The aim of this study was to assess the development of multidrug resistant strains of MRSA from clinical samples andpossibilities for reducing resistance. This study included a total of seventy-five (75) isolates comprising fifteen (15) each collected from ear, urine, cervix, blood and wounds. An agar disc diffusion test was used to measure the effects of antimicrobial agents against the bacteria isolates following  standardized guidelines. Out of a total of 75 clinical isolates of S. aureuscollected, 43 (57.3%) were resistant to methicillin with isolates obtained from ear infections showing the highest resistance pattern of 14.7% while the least was from urine sample with incidence of 5.3%. From the 43 isolates that showed resistance to methicillin, 36 (83.7%) were multidrug resistant to various classes of antibiotics tested.MRSA showed an increasing trend of antimicrobial resistance and therefore calls for periodic surveillance of nosocomial infections due to S. aureus and other important bacterial pathogens.Key Words: methicillin-resistant Staphylococcusaureus, MRSA, multidrug resistance, MD

Production Differential and Resource-Use Efficiency in Cassava Production in Ogun State, Nigeria

This study was focussed to examine production differential and resource use efficiency of traditional and modernfarms, small and large scale farms as well as mono and mixed crop cassava farmers in Nigeria, using as a casestudy farmers in Ogun State, which is one of the highest producers of cassava in the south-west geo-politicalzone. It considered possible causes of the technical inefficiency The study was necessitated because effortsaimed at increasing cassava output cannot be properly directed unless the current levels of factor productivityand technical efficiency of the farms are known, and likely causes of sub-optimal usage of resources areidentified. The study was basically an application of the stochastic frontiers production function to the inputoutputdata collection procedure on selected cassava farmers to estimate the levels of technical efficiency byfarm size, technology used, and cropping systems. The finding implied that the current level of output fromcassava farms can be increased by about 38% for all farms (aggregate), if all farm inputs are effectively utilized.The cassava output (tonnes/ha) was significantly higher for mono crop and large-scale farmers than in mixedcrop and small-scale farmers respectively. Mixed crop farmers who are mainly small holders and who producedother crops in addition to cassava tubers on their farms were however found to be technically more efficient withhigher net farm incomes and returns on investment than mono crop and large-scale farmers, respectively (p ≤0.05). It is also recommended that government should intensify efforts to encourage the small-holders to improveupon their production practices. However, in the long run, large scale enterprise cannot be ruled out; so, theimpediments to large scale cassava production and the factors which make small scale operation less efficient orproductive as compared to the large scale farms should be tackled. Suffice to add that the establishment of largescale farms could ease-off the intensive labour input and thereby making mechanisation more economical.Keywords: Input, Output, Differential, Production, Resource

DETERMINANTS OF FOOD SECURITY STATUS AND INCIDENCE OF FOOD INSECURITY AMONG RURAL FARMING HOUSEHOLDS IN IJEBU DIVISION OF OGUN STATE NIGERIA

This study examined the determinants of food security status and incidence of food insecurity among faming households in Ijebu Division of Ogun State. A sample of 120 farming households was drawn using multistage sampling procedure and the data were analysed using descriptive statistics, food security index and logit model. The study showed that majority of the household heads fall within the age range of 20-60years and the incidence of food insecurity increases with increase in age of household head. Food insecurity incidence was higher among female headed households. Further revelation showed that majority of the respondents are married and the food insecurity incidence is highest among the married respondents. Household heads with no formal education had the highest food insecurity incidence while those with tertiary education had the lowest food insecurity incidence. Household food insecurity incidence increases with increase in household size. Household food insecurity incidence increases with increase in the farming experience of the household head. Food insecurity incidence of households whose heads are cooperative members was found to be lowest. Using the food security index, the survey related that 59.2% of the respondents were food secure while 40.8% were food insecure. The logit model revealed that the socio-economic characteristics of the farming households such as age (10%), education (10%), household size (1%) and farming experience (5%) are the significant factors influencing the food security status of the farming households in the study area. Effort should be made at improving programmes and policies that will ensure a proper family planning especially in the rural area which will reduce the number of children to that which the household can adequately cater for. Nutrition-oriented programmes should be organized in attempt to improve the food substitution knowledge of the farming households.Â

Aspects of microbial contamination of tablets dispensed in hospitals and community pharmacies in Benin City, Nigeria

Purpose: A research was carried out to investigate the incidence of microflora in tablets dispensed from large container packages used in hospitals and community pharmacies. It was designed to provide base-line data on the common biodegrading microorganisms associated with tablets in retail containers and to highlight the health implications of such observations and roles for pharmacists in self medication phenomenon in Nigeria. Methods: The protocol for the study involved structured selection of representative named tablets from some public hospitals and community pharmacies within Benin metropolis. Constitutive microorganisms were elaborated and enumerated using standard microbiological protocols. Results: Our results showed that all the tablets sampled had some form of microbial growth. However, aerobic mesophilic bacteria and fungi observed were within standard numerical limits. It was additionally observed that ascorbic acid and folic acid tablets, particularly from the community pharmacies failed the exclusive criteria for Enterobactereacea and Staphylococci. Tablets from public hospitals in general have lower incidence of exclusive microbial contamination, compared with community pharmacies. Conclusion: Tablets packed in large containers in retail pharmacies in Benin City are often contaminated with microbial growth. This has possible adverse consequences for those who obtain drugs stored in large containers. Keywords: Microflora, tablets, retail packs, hospitals, community pharmacies.

Prevalence of methicillin-resistant staphylococcus aureus among healthy residents of Ekosodin community in Benin-City, Nigeria

Purpose: To determine the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in apparently healthy residents of Ekosodin community, a peri-urban settlement, in Benin City, Nigeria.Method: Nasal swabs collected from 200 randomly selected individuals, aged between 16 and 38 years, were used in the study. Isolates from the swabs were aseptically collected and characterized using standard and established microbiological methods, which included growth and fermentation on mannitol salt agar (MSA), colonial morphology, Gram-staining reaction and biochemical tests. Antimicrobial susceptibility test was performed on Mueller-Hinton agar (MHA) by modified Kirby-Bauer disc diffusion method.Results: S. aureus was isolated in 49.5 % (n = 99) of the 200 nasal swabs. Among these isolates, 43 % were from male residents and 22.2 % (n = 22) were MRSA. The MRSA isolates indicated relatively high rate of resistance to penicillins, moderate resistance to erythromycin and cefuroxime, and leastresistance to gentamicin, streptomycin, ceftriaxone, ciprofloxacin and co-trimoxazole. There was no significant gender difference in terms of the colonization of S. aureus (p < 0.05).Conclusion: Many apparently healthy residents of Ekosodin community are nasal carriers of MSRA. The need for rational chemotherapy, routine detection and regular surveillance of MRSA to limit its spread and reduce treatment failures is vital

Antimicrobial activity of the ethanol extract of the aerial parts of sida acuta burm.f. (malvaceae)

Purpose: The antimicrobial activity of the 90 % ethanol extract of the aerial parts of Sida acuta Burm. F. (Malvaceae) was investigated in other to verify its claimed ethno medicinal use in the treatment of microbial infections. Method: The antimicrobial activity of the extract was tested against standard strains and clinical isolates of some aerobic bacteria and a fungus using the Agar well diffusion method. Commercial antibiotics were used as positive reference standards to determine the sensitivity of the strains. Results: The extracts showed significant inhibitory activity against standard strains and clinical isolates of Staphylococcus aureus, clinical isolates of Bacillus subtilis and Streptococcus faecalis. The MIC values obtained using the Agar-dilution test ranged from 5.0 mg/ml. – 10.0 mg/ml. Neither the concentrated extract nor its dilutions inhibited Esherichia coli, Klebsiella pneumonia, Pseudomonas aeruginosa and Candida albicans Conclusion: The results demonstrate that the crude extract of the aerial parts of Sida acuta has a narrow spectrum of activity and suggest that it may be useful in the treatment of infections caused by Gram positive aerobic bacteria. Keywords: Sida acuta, ethanol extract, antimicrobial activity. Tropical Journal of Pharmaceutical Research Vol. 6 (4) 2007: pp. 809-81

Technology Adoption among Cassava Producers in Ijebu North-East Local Government Area of Ogun State

The main objective of this research work was to find out the adoption of technology among cassava producers in the study area. A multistage random sampling procedure was adopted to collect primary data from 80 cassava farmers who were randomly selected from some selected communities in the study area. Descriptive statistics, logit regression analysis and budgetary analysis were used to analyze the data collected. The result revealed that majority of the respondents have low formal education, as about 68% of the farmers only attended primary school, 67% of respondents fall within the age bracket of 31 to 50 years which is the normal age group for the working population, also revealing that majority of the respondents (farmers) are males with about 78% of entire respondents being males, the research also revealed that 91% of the farmers are married with an average income of N34,153.21. Furthermore, the regression analysis showed that age of farmers, farm size, hired labour (mandays) and cropping patterns showed significant influence at different levels on the probability of adopting improved technologies in cassava production as age had a positive and significant influence on the probability of adopting improved technologies. This influence is significant at 10% level. The coefficient of farmer’s age and education is positive meaning that as farmers age increase by one unit, the probability of adopting improved technologies will also increase. The budgetary analysis revealed that the average total revenue is N34,153.52, the average farmer’s net income is N22,094.99 and gross margin is N25,818.77 with the profitability index as 0.6469. Based on the problems identified, it has been recommended that the government should provide incentives for the farmers as well as increasing the rate of visit of extension agents in the study area so as to boost their level of adoption of technologies on cassava farming.
