Organization learning and business resilience in developing hospitality industry

The study aims to investigate the effect of organizational learning on business resilience in developing the hospitality industry, specifically focusing on four-star hotels in the southeast region of Nigeria. One of the major reasons why this research was conducted is because of the vacuum that exists between organizational learning and business resilience in the hospitality industry. A cross-sectional survey design was employed because it supports using questionnaires to collect data from participants. A validated and reliable instrument was used to collect data from two hundred thirty one participants drawn from the selected hospitality industry in the southern part of Nigeria. The results demonstrate that organizational learning significantly positively affects business resilience. Organizational learning also affects crisis anticipation and recoverability which are crucial to be resilient in the industry. The results of this research supported prior empirical findings and supported both social learning theory and resilience theory. Regarding originality, the geographical scope and the industry where this research was conducted distinguish it from other prior empirical investigations. It was recommended that since the hospitality business is highly competitive, managers should utilize organizational learning as a strategy to overcome their competitors and remain sustainable in the industry. The findings of the research will contribute to the literature and hospitality industry in developing country contexts.

Cybercrime And Its Negative Effects In Developing Countries

Background: This paper investigates the prevalence and the negative impacts of cybercrime in developing countries. It also attempts to proffer solution to the problem of cybercrime focusing on identity theft, phishing, and other cybercriminal activities that are common in 21st century. This research is imperative because cybercrime has become a teething problem to most developing countries where monitoring and tracking of cybercrime offenders is still a big challenge. In Nigeria for example, cybercrime comes in different forms and affects almost all aspect of human endeavor in our day due to the rapid expansion of internet access and digital technologies. Materials and Methods: The research employs a mixed-method approach. First, it took a tour on different established cases of cybercrimes in recent time. It then carried out real life survey using a sample of about 68 students studying computing science in some universities in the southern part of Nigeria. Results: Findings reveal a high level of concern about cybercrime among respondents, with many reporting personal experiences such as phishing attempts and identity theft via social media platforms like Facebook and Instagram. The discussion emphasizes the importance of cybersecurity education and robust government regulations to combat cyber threats effectively. Conclusion: Recommendations include addressing youth unemployment, promoting ethical wealth generation, and strengthening cyber security laws to mitigate the socioeconomic and moral impacts of cybercrime in developing countries. This study contributes to understanding the multifaceted challenges posed by cybercrime in developing nations and underscores the necessity for comprehensive strategies encompassing policy reforms, educational initiatives, and socioeconomic interventions

The language of Nigerian stand-up comedy

Nigeria is complexly multilingual. Arising from this, Nigerian stand–up comedians employ a variety of linguistic strategies to communicate with the audience. This research investigates the peculiarities of language use in Nigerian stand-up comedy by analysing patterns of code choices in the comic performances of four comedians. Because the stand-up comedy industry is predominant in the Southern part of Nigeria, the comedians chosen for this study are representative of the three geopolitical zones of southern Nigeria. The analysis of the data indicates that (1) although Nigerian stand-up comedians primarily use Nigerian Pidgin (NP) they also employ language alternation and code-switch between NP, English, and a variety of indigenous languages. (2) NP is mainly used in the oral medium. Consequently, features of orality: repetition, parallel structures, anaphora, lexical cushioning, semantic extension, metaphor imagery, sentence fragments, and rhetorical devices, are other dominant features of Nigerian stand-up comedy.

Analysis of craniofacial indices of dry crania in Southeast and Southsouth Nigeria

Objective: To determine the cranial index, upper facial index and frontal index of dry human crania in Nigeria. Methods: A total of 150 dry adult male crania were studied in two geopolitical zones (Southeast and Southsouth) in Nigeria. Measurements were taken with spreading caliper and Vernier caliper. The following variables were measured: Maximum cranial length (MCL, g-op), Maximum cranial breadth (MCB, eu-eu), Minimum frontal breadth (MFB, ft–ft), Upper facial height (UFH, n-pr) and Bizygomatic breadth (BZB, zy-zy). From these variables, cranial index (CI), frontal index (FI) and upper facial index (UFI) were calculated. Data analysis was done with the Statistical Package for Social Sciences (SPSS version 25). Result: In the Southeast group, the values of MCL, MCB, BZB, UFH and MFB (in mm) were 181.4 (±10.3), 135.3 (±6.7), 135.3 (±6.0), 68.0 (±4.1) and 97.9 (±7.4) respectively. In the Southsouth group, the values of MCL, MCB, BZB, UFH and MFB (in mm) were 180.0 (±7.8), 133.9 (±6.7), 135.0 (±7.2), 67.5 (±6.6), and 98.1 (±4.9) respectively. There was no significant difference in these means between the Southeast and Southsouth groups. In the Southeast group, the mean values of CI, FI and UFI (in %) were 75.1 (±5.9), 72.7 (±5.9), and 50.5 (±3.4) respectively. In the Southsouth group the mean values of CI, FI and UFI (in %) were 74.5 (±4.0), 73.3 (±3.6) and 50.0 (±4.4) respectively. There was no significant difference in the means of the cranial indices among the two groups. Conclusion: The crania in the southern part of Nigeria are dolichocephalic, eurymetopia and mesene type.

Pattern of IVU among patients presenting with flank pain at a tertiary hospital in Rivers State

Background: Intravenous urography (IVU) is a contrast based radiological procedure for the investigation and imaging of the urinary system. It was the gold standard, not until the last two decades when CTU (computed tomography urography) took over. The latter is better because of its improved accuracy in the diagnosis of urinary tract pathologies. Flank pain is a sensation of discomfort or distress in the part of the body below the rib and above the ilium. The possible organs in the flank to be affected include kidney and ureter. Aim This study is aimed at finding out the IVU findings in patients presenting with flank pain in a tertiary hospital in the southern part of Nigeria. Study design and settings: A retrospective study was conducted in the Radiology Department of Rivers State University Teaching Hospital (RSUTH) from 1st February 2021 to 10th February 2023. Data Analysis: Data was analyzed using SPSS 20.1 version. The level of statistical significance was set at p<0.05. Results: A total of 100 data was analyzed. Patients between the age of 5 years and 76 years with a mean age of 39.72 + 14.33 years was used for this study. Majority of the age group was greater than 41years of age with an equal male to female distribution. That is the ratio of female to male in this study is 1:1. The study shows that more patients had abnormal IVU patterns than normal. More females had normal IVU patterns while abnormal IVU patterns were more common in males. The study also shows that the ureters were more affected than the kidneys because we had more abnormal IVU pattern in the ureter than the kidney. Conclusion: The age group with the highest abnormal IVU pattern is the greater than 41years group, probably because they were more in number in the study population and again may be, we can say the frequency of diseases increases with increasing age.

Gastrointestinal Helminth Parasites, Stomach Contents and Condition Factor of Bostrychus africanus (Sleeper gobies) and Periophthalmus papilio (Mudskipper) found in Ikpukulu-Ama Creek, Port Harcourt, Rivers State, Nigeria

Aim: Bostrychus africanus and Periophthalmus papilio are important fisheries in parts of southern Nigeria. However, there is a dearth of information on the gastrointestinal helminths of these gobiids, especially from the Ikpukulu-Ama Creek, Port Harcourt, Rivers State, Nigeria. This research was, therefore, necessary to provide information on the parasites as well as stomach content analysis and condition factor of both fish species.
 Study Design: A total of 62 Bostrychus africanus and thirty-six (36) Periophthalmus papilio were caught for analysis using basket traps on the mudflats of the creek.
 Place and Duration of Study: Sampling was done at the Ikpukulu-Ama Creek, Port Harcourt, Rivers State, Nigeria in September, 2023.
 Methodology: In the laboratory, samples were identified using morphometric characteristics and identification keys and examined for parasites using standard diagnostic techniques.
 Results: Nematodes, Raphidascaroides africanus (16.1%), were examined from B. africanus, whereas acanthocephalans, Neoechinorhynchus sp. (2.8%), were observed from P. papilio. The result of this study suggests a parasite preference of B. africanus over P. papilio. Stomach content analysis showed the presence of crab parts and muddy sediments in B. africanus. Condition factor was better in B. africanus (1.1 to 1.8) than in P. papilio (0.7 to 1.1).
 Conclusion: There is a dearth of information on the stomach content of P. papilio and therefore, is suggested for future studies, and scientific reasons for the parasite preference of B. africanus over P. papilio should be elucidated.

Quantitative Models for Supply Chain Risk Analysis in Water Tank Manufacturing: A Case Study of a Factory in Aba, Nigeria

Quantitative models for supply chain risk analysis of water tank manufacturing company factory Aba, Abia state has been studied. Aba being one of the biggest cities known for commercial activities in southern part of Nigeria, couple the weight of weight and area of a water tank, has made the supply mechanism of the product costly. This study delves into the complexities of supply chain management, aiming to identify risk assessment models, vulnerabilities, propose optimal scenarios, and recommend enhanced risk management strategies. Risk factors identification, route time estimation, critical path analysis, cost-related risk assessment, comparison of logistic choices, and decision tree and mitigation were used to instigate and determine the best path for the supply flow of the system and save cost. From the results obtained, the analysis reveals that PATH 6 is the most time-efficient route, with the critical path identified as 62 hours, furthermore, two transportation/logistic choices were compared, with the second choice considered more cost-effective (N6.6m) than the first (N6.9m), the developed decision tree model, explores vulnerabilities in the supply chain and proposes mitigation strategies. This research has suggested some applicable guides to optimize supply chain managements, which includes partnering with distributors, leasing warehouses, or collaborating with retailers, with each decision weighed against various factors and costs to align with the company's best interests. The study underscores the importance of considering every component of the supply chain during decision-making to effectively mitigate risks.

Cocoa, Palm Tree, and Cassava Plantations among Smallholder Farmers: Toward Policy and Technological Efficiencies for Sustainable Socio-Economic Development in Southern Nigeria

This study is basically and centrally focused on the review of the extant literature in exploring the challenge of the under-utilization of natural fertile land for the cultivation and farming of different crops such as cocoa, palm tree, and cassava, which remain an important sector of the economy for sustainable socio-economic development in the southern part of Nigeria. The review of the cursory literature is necessary to bridge the gap in the existing body of knowledge, especially by addressing the less attention paid to exploring the non-oil sector of the economy such as cocoa, palm tree, and cassava as well as connecting policy and agro-technology to maximize agricultural productivity for the purpose of sustainable socio-economic development. The primary objective of this study is to explore cocoa, palm tree, and cassava plantations among smallholder farmers in order to enhance sustainable socio-economic development in the country. The methodology used in this study is a systematic literature review (SLR) cum content analysis (CA) of secondary sources or relevant literature whereby six themes were generated and analyzed. A consistent approach was used in order to establish exhaustive searching strategies and single-line search strategies such as using field codes and parentheses as part of a systematic literature review. The results indicated that smallholder farmers have been actively partaking in cocoa plantation, and the government has been supportive of them in this regard in order to achieve sustainable socio-economic development. In addition, agricultural transformation contributes to economic diversification through innovative policy and capacity building among cocoa, palm tree, and cassava farmers in the country, which culminates in improving the overall welfare of the smallholder farmers in attaining sustainable socio-economic development. In conclusion, it is noteworthy to say that giving support, especially cocoa, palm tree, and cassava seedlings, to smallholder farmers can be instrumental in bridging the vacuum created by poverty and unemployment which could be regarded as mechanisms for attaining sustainable development. The importance of the study was manifested in the practical aspect of giving concrete support to the smallholder farmers, and the innovativeness of the study is reflected in the advocacy for the efficiencies and effectiveness of agricultural policy and technology integration into the sector. It is therefore suggested that interventions of individual philanthropists, government, and international communities will boost the morale and resilience of the farmers toward enhancing cocoa, palm tree, and cassava production in order to enhance sustainable socio-economic development among smallholder farmers in particular and to maximize national economy growth in general.

ISOLATION OF SITOSTEROL AND STIGMASTEROL FROM THE ROOTS OF CROTON PENDULIFLORUS

The primary aim of this study was to isolate Sitosterol from the root of Croton Penduliflorus. Croton Penduliflorus Hutch (Euphorbiaceae) commonly known as Turk’s Cap though to originate from Malaysia, is a tropical evergreen plant widely distributed in the southern part of Nigeria. It is employed in folklore medicine both as drastic and fugitive, as well as a psychotropic medicinal plant. It is also credited with antimicrobial, antivenom, antiparalytical, rubefacient and anti-tumor potencies Extraction of the roots of Croton Penduliflorus with ethanol and partitioning of the extract with hexane, chloroform and ethyl acetate followed by column chromatography of the chloroform extract has led to the isolation of sitosterol, stigmasterol and a substituted benzene derivative. Their structures were established using 1D and 2D NMR, LCMS, and FTIR spectral analysis and a comparison of their spectral data with literature reports.

A Short Review on Fluoride and Arsenic Constituents in Nigerian Groundwater Networks: Causes, Effects and Suggested Removal Methods

The quality of water cannot be overlooked as it is an important element required by every being in existence. Water majorly is used as drinking water and if not properly looked after could lead to various health and environmental issues. Fluoride and arsenic are naturally occurring pollutants with their sources being traced to either anthropogenic or geogenic contributions. It is imperative to note that excessive consumption of fluoride and arsenic in water could result to serious health challenges. Elevated constituents of fluoride and arsenic in water have been reported in the northern and southern parts of Nigeria, but their concentrations are more prevalent in the north. The contaminants have been traced to some activities such as mining, improper disposal sites, agricultural practices, industrial effluents among others. Adsorption process has been suggested as the cost effective and environmentally friendly defluoridation, while nanofiltration membranes is the best removal process for arsenic in water.

Assessment of Effluent Recycling Process and Drilling Waste Management Procedure in Some Niger Delta States

The assessment of effluent recycling process and drilling waste management procedure in some Niger Delta States in Nigeria to identify ways to minimize cost in oil production, have been investigated. Niger Delta States are located in southern part of Nigeria, which are known to be the highest in crude oil production in Nigeria, however, the process of exploration and extracting of the oil also affects the ecosystem of that particular area. A comparative design was taken, which analysed various indices in the conventional methods of drilling waste management applied in a site in Edo State northern part of Nigeria, and comparing it to some modified methods employed in the wellhole locations in Imo State. The research was conducted in a wellhole site located in Ohaji Imo state, southern part of Nigeria, afterward, a correlation was drawn between the volume of generated waste and the drilling waste management, in order to develop a cost-effective model of waste management in the region. From the result obtained from the quantitative measures taken at the four drilling sites in Edo and Imo States, a significant reduction in waste volume of about 50% was observed, which therefore minimized the cost of drilling observed in Ohaji site, maybe as a result of the enhanced drilling design layouts using the effluent recycling method adopted in that location. The study therefore recommends the adoption of effluent recycling as a technique to be incorporated in the management of drilling waste during onshore petroleum development in the Niger Delta, among others, which would improve productivity.

Soil-transmitted helminthiasis (STH) endemicity and performance of preventive chemotherapy intervention programme in Nigeria (in year 2021)

Preventive chemotherapy (PC) is an important tool to address transmission and reduce morbidities associated with soil-transmitted helminths (STHs). The aim of the study is to assess the PC implementation programme coverage and relate the same to the endemicity of STH in Nigeria. The secondary data collected by the World Health Organization (WHO) through the expanded special project for elimination of neglected tropical diseases (ESPEN) and made available at the ESPEN portal was used for the study. The PC implementation coverage and frequency of treatment were evaluated and related to STH endemicity levels in Nigeria. STH was actively transmitted in all six geopolitical zones of Nigeria. The southern part of Nigeria was more endemic compared with northern Nigeria. There was no PC intervention in preschoolers and effective PC coverage (19.3%) fell below the WHO ≥ 75% PC coverage index benchmark in school children. The percentages of children that harbour low, moderate, and high STH infections were 41.5, 41.6, and 13.4%, respectively. Multiple treatments did not necessarily reduce the endemicity of STH on certain occasions. STH continues to be a public health threat in Nigeria. The current treatment strategies should be reviewed to accommodate preschoolers in PC implementation programmes. Treatment should be integrated with the WASH programme in order to achieve a lasting impact.

Mineralogy and geochemical characterization of geophagic clays consumed in parts of southern Nigeria

This study seeks to determine health risk associated with consumption of clay in different areas in southern Nigeria. Different clay samples sold for consumption were purchased from Mowe, Ikorodu and Onitsha Markets in southern Nigeria. The clays were subjected to mineralogical and geochemical characterization using X-Ray Diffractometry (XRD), Fourier Transform Infrared (FTIR) and Inductively Coupled Plasma-Atomic EmissionSpectrometry. Potential health risk assessment was calculated using a standardized Hazard Quotient (HQ) and Total Hazard Index (THI). XRD and FTIR results revealed the clay contains varying percentage of quartz, kaolinite, anatase, halite, pyrite, goethite, smectite and palygorskite while geochemical analysis result revealed wide range of elemental concentration (ppm). Mean concentration (ppm) of Cu, Pb, Zn, Cr, Ni and Co from the markets are 5.8 – 8; 17.4 – 29.6; 32.4 – 95.8;111.6 – 103.4; 18.6 – 39.4 and 4 – 16.6 respectively while As was below detection limit in most of the samples. HQ values were used to calculate the THI. THI values for children and adults for Mowe market samples range from 0.9 to 2.1 and 0.5–1.1 respectively, for Ikorodu market samples, THI for children and adult ranges from 1.0- 1.8 and 0.6–1.0 respectively, while THI for children and adults for Onitsha market samples ranges from 1.5 to 2.6 and 0.8–1.84 respectively. In conclusion, children that consume clay from the markets are more exposed to non-carcinogenic risks than adults. It is therefore advisable that the clays should not be consumed for a long period of time to avoid health problems.

Islamic prescriptions for cattle rearing: A complementary approach towards curbing farmer-herder clashes in Nigeria

The recurrence of violence across Nigeria is worrisome. Among the incidents are the clashes between Fulani Muslim herders andChristian farmers, especially in the middle belt and parts of southern Nigeria. Efforts of the government at curbing theseclashes have not yielded desired results. Can religion (Islam) complement governmental interventions in the resolution of theproblem? This paper focused on a historical and analytic exploration of this question. It was found that clashes were causedby the open grazing system of cattle rearing adopted by Fulani herdsmen. This system exposes cattle to dangers, destroys crops on farmlands, and causes collisions on roads/highways. It was also revealed that the non-adherence to Islamic prescriptions on animal welfare was an important additional factor. The paper posits that criminal activities such as rape, killing, and destruction of property alleged to have been committed by Fulani Muslim herders are condemnable and punishable by Islamic law. To achieve better results in the search for peaceful co-existence, it is recommended that the federal government and state administrations establish ranches and grazing reserves, implement the National Livestock Transformation Plan, and collaborate with religious leaders to motivate herders to keep Islamic laws of cattle rearing.

Impression Management and Employee Contextual Performance in Service Organizations (Enterprises)

This study aims to investigate the effect of impression management on employee contextual performance in service organizations using quantitative methods. The social influence theory, which explains the role of superior influence over the subordinate, served as the theoretical underpinning for the study. A cross-sectional survey design was adopted in line with positivism research philosophy. The accessible population of this study consists of one hundred selected service-oriented firms (four-star hotels, fast food restaurants, and travel agencies) operating in the southern part of Nigeria. The sample consists of middle managers, human resource managers, front desk officers, housekeepers, and customer relationship managers. Frequency distribution was used to analyze participants’ profiles, while linear regression was employed to analyze the formulated hypotheses. Statistical Package for the Social Sciences (SPSS) 20.0 served as statistical software. Linear regression results suggest that self-promotion exerted a significant positive effect on co-worker support. Ingratiation demonstrated a significant positive effect on customer satisfaction. It appears that exemplification exerted a significant positive effect on enterprise compliance. The outcome of this study has demonstrated that traditional managerial skills can no longer hold water in contemporary service-oriented organizations because of the workplace's dynamic and changing technological structure. This study concludes that impression management can assist managers in influencing their employees positively to achieve organizational objectives. Doi: 10.28991/ESJ-2023-07-02-05 Full Text: PDF

The response of benthic foraminifera to environmental changes in Epie creek, Yenagoa, Bayelsa State

Epie creek, located at the Southern part of Nigeria has been known for its use as sink for the disposal of untreated sewage and industrial effluents. Benthic foraminifera are increasingly been used as environmental bio-indicators of pollution. Their munity structure provides information on the general characteristics of the environment and some species are sensitive to specific environmental parameters. This study investigates recent foraminifera from sediment samples collected from ten (10) stations (ranging in depths from 1m to 4.2m) in the Epie creek from Igbogene to Tombia- Etegwe. The environmental factors that necessitate their existence such as temperature, pH, salinity and dissolved oxygen were measured during the sampling time. Metals were determined using atomic absorption spectrophotometer. Recognized benthic foraminifera species belonging to four (4) genera of three (3) families and four(4) suborder were identified. Five (5) benthic foraminifera taxa were identified from sediment samples which include Lenticulina stellata, Saccammina sp, Marginulina costata, Marginulina cf. planata and Trochammina sp. The stress tolerant specie, Trochammina ,sp. was common in the study area confirming a stressed environment.
