Environmental scanning strategy of manufacturing companies in Southwestern Nigeria

In this paper, we examine the environmental scanning strategy of manufacturing companies in Southwestern Nigeria against the background that manufacturing companies in Nigeria exist in a challenging environment characterised by high import dependency, inappropriate policies, lack of transparent governance and weak industrial capabilities. Empirical data was collected with a questionnaire from a sample of 84 manufacturing firms in Southwestern Nigeria. We found that generally, companies in the industry actively engage in systematic gathering, analyses and assimilation of information about the business environment as strategic input into planning. The main objective of search was to obtain information required to initiate or support strategies for competing in the domestic market. Central among the factors determining the companies' level of intrusiveness into the environment are companies' capacity to interpret changes in the environment, available channels of information and quality of information.business environment; environmental scanning; environmental analysability; environmental uncertainty; manufacturing, strategy; technology; capabilities

Comparison of clinical profiles and treatment outcomes between vagrant and non-vagrant mentally ill patients in a specialist neuropsychiatric hospital in Nigeria

Objective: Vagrant mentally ill patients are a highly marginalized group that receive limited care and attention from society. There is a dearth of information on the clinical status of this group in low-income countries. The aim of this study was to compare the clinical profiles and treatment outcomes between vagrant and non-vagrant mentally ill patients admitted to Aro Psychiatric Hospital, Abeokuta, Nigeria. Method: We conducted a retrospective review of clinical records charting vagrant and non-vagrant mentally ill patients treated over a five year period from January 2004 to December 2008. Results: The medical records of 61 vagrant and 122 non-vagrant mentally ill patients were reviewed and compared. The vagrant patients were more likely to be older, unmarried and alone, poorly educated, unemployed or performing unskilled labour, and diagnosed with schizophrenia. This cohort was also more likely to have physical co-morbidities compared with the non-vagrant mentally ill patients. The median time to improvement among the vagrants (211.0 days) was significantly longer than for the non-vagrant patients (34.0 days) suggesting more intractable illnesses. Other factors found to prolong the time to improvement among all patients were old age, education, being single, unemployment, the diagnoses of schizophrenia, and substance abuse. Conclusion: The clinical profiles and treatment outcomes were poorer among the vagrant mentally ill patients, underscoring a need for more comprehensive healthcare resources directed to this patient group in Nigeria.Key words: Vagrant; mental illness; clinical profile; outcome; Nigeri

Survey of free-range animals within Federal University of Agriculture, Abeokuta Zoo Park, Nigeria

The study examined the abundance of free-range natural inhabitants of Federal University of Agriculture, Abeokuta (FUNAAB) Zoo Park. A  baseline data of free ranging inhabitants of the Park is essential to monitor trends and institute conservation plans through unsustainable natural resources exploitation and habitat destruction. Four transects were selected across the study area. Each transect was traversed for the period of four months and observations were carried out twice a day. The Four existing tracks explored during the study were the  aviary, reptile, carnivore and primate tracks. Data were analyzed using descriptive statistic. The findings from this study revealed that 8 species of natural inhabitants were identified which were Chlorocebus pygerythrus,Philantomba maxwellii, Herpestidae spp, Tragelaphus scriptus, Naja naja, Marmotini spp, Centropus senegalensis and Milvus migrans. The result further showed that a total of 115 animals were encountered in the primate transect, 77 animals in carnivores transect, 46 animals in aviary transect and 34 animals in ungulates transect by representative of 43.3%, 28.3%, 15.8% and 12.5% respectively. Human activities and level of disturbance was observed to have affected the abundance and distribution of animals at FUNAAB Zoo Park. Continuous field inventory is recommended to ascertain the dynamics of animals observed as free- range inhabitants in this study

Hydrocarbon-degrading bacteria isolation and surfactant influence on the growth of organisms: A case study in Ibadan, Nigeria

Hydrocarbons are substantially insoluble in water, often remaining partitioned in the non-aqueous phase liquid (NAPL). However, there had been little or no attempts to advance the bioavailability of hydrocarbons through the use of surfactants. This study was conducted based on the need to isolate hydrocarbon degrading bacteria and to establish the effect of surfactants on the growth of organisms. Ten organisms were isolated and classified into five genera based on their physiological, morphological and biochemical characteristics. These genera include Pseudomonas, Bacillus, Micrococcus, Flavobacterium and Corynebacterium. In determining the effect of surfactant on isolated organisms, Bacillus strain and Corynebacterium strains were enhanced by palmitic acid. Detergent was found to have stimulatory effect on Bacillus and Pseudomonas. There is a significant difference between separate applications of palmitic acid and detergent on the samples with respect to the growth of Micrococcus sp. (p < 0.01). There was also a significant difference between the applications of detergent and control on the selected samples with respect to Flavobacterium sp. (p < 0.001). Surfactant which stimulated bacterial growth is highly recommended in bioremediation, although the use of improved strains may be preferable.Keywords: Hydrocarbons, surfactants, biodegradation, pollutants, microoganism

Agricultural Extension Agents’ Awareness Of Ict Potentials And Training Needs On Usage For Improved Extension Service Deliv- Ery In Selected Southwest States Of Nigeria

The   study   examined   the   agricultural   extension   workers’ awareness   of   ICT   potentials   and   training needs on ICT usage for improved extension service delivery in selected southwest states of Nigeria. A multistage sampling technique was used to select a total of 132 extension workers’ from Lagos and Ogun States Agricultural Development   Programmes   (LADA  and OGADEP).   A  validated  and  reliable questionnaire was used to obtain primary data on socioeconomic characteristics of the respondents, their awareness of ICT potentials and training needs on ICT usage for improved extension services delivery. Data collected were analysed using frequency counts, percentages and chi-square statistics. Result of the analysis showed that most of the respondents were the Village Extension Agents (78.8 %,), and about 34.1% of them were within the age range of 41 and 45years. About 72.7% the exten- sion agents had first degree (HND/BSc) as the least educational qualification and about 57.6% of them have spent between 11 and 20 years in the extension services. The result also showed that all the extension agents were familiar with the Global System Mobile communication (GSM), 58.3% with the computer and 38.6% of them with the internet. About 43.2% of the extension workers were moderately aware of the ICT potentials for improved extension service delivery based on their mean awareness score of 8.5 (53.1%). The chi-square test of the relationship between the extension workers’ socioeco- nomic characteristics (education: χ² = 45.5,  df = 12; professional rank: χ² = 38.7,  df = 9; working ex- perience χ² = 65.2, df = 12) and level of awareness of the ICT potentials showed a significant relation- ship at p < 0.05. Similarly, a significant relationship was observed between the extension agents’ level of awareness of ICT potentials and their needs for training on usage for improved extension service delivery (χ² = 71.3, df = 18) at p < 0.05. In the light of this, it was concluded that the extension workers had moderate level awareness of ICT potentials for improved extension services and were in need of training on usage in their extension activities. It was recommended that education on ICT potentials and   training on  usage for improved  extension service delivery   should   be promoted and intensified among the extension workers.      &nbsp

Intelligent Phishing Detection Scheme Using Deep Learning Algorithms

Purpose: Phishing attacks have evolved in recent years due to high-tech-enabled economic growth worldwide. The rise in all types of fraud loss in 2019 has been attributed to the increase in deception scams and impersonation, as well as to sophisticated online attacks such as phishing. The global impact of phishing attacks will continue to intensify, and thus, a more efficient phishing detection method is required to protect online user activities. To address this need, this study focussed on the design and development of a deep learning-based phishing detection solution that leveraged the universal resource locator and website content such as images, text and frames. Design/methodology/approach: Deep learning techniques are efficient for natural language and image classification. In this study, the convolutional neural network (CNN) and the long short-term memory (LSTM) algorithm were used to build a hybrid classification model named the intelligent phishing detection system (IPDS). To build the proposed model, the CNN and LSTM classifier were trained by using 1m universal resource locators and over 10,000 images. Then, the sensitivity of the proposed model was determined by considering various factors such as the type of feature, number of misclassifications and split issues. Findings: An extensive experimental analysis was conducted to evaluate and compare the effectiveness of the IPDS in detecting phishing web pages and phishing attacks when applied to large data sets. The results showed that the model achieved an accuracy rate of 93.28% and an average detection time of 25 s. Originality/value: The hybrid approach using deep learning algorithm of both the CNN and LSTM methods was used in this research work. On the one hand, the combination of both CNN and LSTM was used to resolve the problem of a large data set and higher classifier prediction performance. Hence, combining the two methods leads to a better result with less training time for LSTM and CNN architecture, while using the image, frame and text features as a hybrid for our model detection. The hybrid features and IPDS classifier for phishing detection were the novelty of this study to the best of the authors' knowledge

Effects of Garlic Feed Inclusion on Experimental Salmonella gallinarum Infection in Broiler Chickens (Gallus gallus domesticus)

Garlic is a spice and herbal medicine with antibacterial, antioxidant and immunomodulatory effects. In view of global demand for reduction in antibiotic use in poultry production, the potential of garlic at controlling fowl typhoid was investigated. Day-old (75) broiler chicks were separated into groups A, B, C, D and E of fifteen each, placed in cages for brooding and administered 0.125%, 0.25%, 0.5%, 0% and 0.125% garlic-meal, respectively, in feed. At 9 week-old, each chick in groups A, B, C and D were inoculated with 8x106 cfu/ml PBS of Salmonella gallinarum, orally, while those in Group E were given PBS only. Up till 10 days post-infection (pi), clinical signs were scored from 1-3 based on degree of severity i.e. 1(mild), 2 (moderate) and 3 (severe). Mortality and gross pathology per group were recorded. Samples from liver and gall bladder were harvested for bacterial re-isolation. Groups A, B and C showed mild diarrhoea while group D showed in addition, anorexia, ruffled feathers and unthriftiness. Diarrhoea in groups A and B spanned days 2 -7 pi, group C on day 3 pi while in group D, days 1-10 pi with increasing degree of severity. Total diarrhoea scores were 6(A), 4(B), 1(C), 23(D) and 0(E) while mortalities were 2(A), 0(B), 2(C), 4(D) and 0(E). Enlarged and congested/bronze-coloured liver, engorged gall bladder and catarrhal enteritis were observed in carcasses. Colonial and cellular morphology of re-isolated bacteria were typical of S. Gallinarum. Garlic-meal ameliorated the effects of S. Gallinarum infection with the best result at 0.25%. Keywords: broiler chickens; antibacterial; fowl typhoid; Garlic; Salmonella gallinaru

Maternal education and diarrhea among children aged 0-24 months in Nigeria

Childhood diarrhea remains a problem in countries like Nigeria where access to potable water, good hygiene and sanitation are lacking. Maternal education is an important determinant of health status of under-five children. Very few studies have investigated the relationship between maternal education and diarrhea in children in Nigeria. Therefore, this study was implemented to fill the gap. The study design was cross-sectional and 2013 National Survey was used. Children aged 0-24 months were investigated and the dependent variable was diarrhea status of the index child in the last two weeks prior the survey. The main independent variable was maternal education. Data were analyzed using Chi-square and Logistic regression models (α=0.05). Diarrhea prevalence was 13.7% and higher (15.5%) among children of women who have no formal education, and mothers living in the North East region of Nigeria experienced the highest prevalence (26.4%). Children whose mothers had no formal education were 2.69(CI= 1.800-4.015, p<0.001) more likely to have diarrhea as compared to those who had higher education. Maternal education is an important predictor of diarrhea among children aged 0-24 months in Nigeria. Policies to reduce diarrhea among children in Nigeria should target children of the illiterate, less educated mothers and those living in the North-West.Keywords: Maternal Education, Childhood diarrhea, Nigeri

Kinetic field dissipation and fate of endosulfan after application on theobroma cacao farm in tropical Southwestern Nigeria

Endosulfan, 6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6,9-methano,2,4,3-benzodioxathiepin-3-oxide, is still a pesticide of choice for most cocoa farmers in Southwestern Nigeria, in spite of its persistence, bioaccumulative, toxicological properties, and restriction. A single treatment of 1.4 kg ai/ha (0.5% ai) of technical grade endosulfan (Thiodan, 35EC) was applied to 0.0227 ha of cultivated Theobroma cacao L. (Cocoa) farm at the Cocoa Research Institute of Nigeria (CRIN). Levels of parent endosulfan (α-, β-endosulfan) and major metabolite (endosulfan sulfate) were determined in vegetation and surrounding matrices at days 0, 7, 14, 21, 28, 42, and 60 using GC-MS. Their kinetic variables were determined. Order of ∑endosulfan distribution at day 0 was dry foliage > fresh foliage > bark > pods > soil (0–15 cm). No residual endosulfan was found in cocoa seeds and subsurface soil (15–30 cm). Low residual levels in pods on day 0 may be due to endogenous enzymatic breakdown, with α-isomer more susceptible and α/β-endosulfan ratio being 0.90. Fell dry foliage as mulch was predominantly the receiving matrix for non-target endosulfan sprayed. Volatilization was key in endosulfan dissipation between days 0 and 7 from foliage surfaces (> 60% loss), while dissipation trend was bi-phasic and tri-phasic for vegetation and soil, respectively. ∑endosulfan loss at terminal day ranged between 40.60% (topsoil) and 99.47% (fresh foliage). Iteratively computed half-lives (DT′ 50 ) ranged from 6.48 to 30.13 days for ∑endosulfan in vegetation. Endosulfan was moderately persistent in pods—a potential source for cross contamination of seeds during harvest. Iteratively determined DT′ 50 and initial-final day DT 50 are highly correlated (R = 0.9525; n = 28) and no significant difference (P = 0.05) for both methods

Blood chemistry, haematological indices and nutrient digestibility of starter turkeys fed macaroni waste meal as a replacement for maize.

A 56-days experiment was carried out to study the effect of replacing macaroni waste meal (MWM) with maize on nutrient digestibility and blood chemistry of indigenous turkey starter. Ninety-six indigenous turkey poults with an average weight of 52 g were randomly assigned to four dietary treatments containing macaroni waste meal at 0%, 15%, 30% and 45% level as replacement for maize. Each treatment consist of 24 turkey poults replicated thrice with 8 turkeys per replicate. A three day metabolic study trial was carried out for nutrient digestibility determination. Blood samples were also collected for serum and haematological indices. Data collected were subjected to one way analysis of variance. Result showed that MWM at 15% had the highest values for packed cell volume, red blood cell, white blood cell while values recorded for serum uric acid and creatinine were significantly lower (P0.05). However, the packed cell volume, red blood cell count, albumin, hemoglobin, total serum protein and serum glucose. It can be concluded that MWM could be incorporated into the diet of indigenous turkey starter at 15% level without any deleterious effect on nutrient digestibility and blood chemistry
