A survey of the market diseases and aflatoxin contamination of tomato fruits was conducted in Sokoto in northwestern Nigeria in 2001 and 2002, respectively. Rotten tomato fruits sold at five different markets in Sokoto town, located at Central market, Kasuwar daji, Mabera, Minanata and Arkilla were heavily contaminated with moulds. Eight different fungi were found associated with the rotten tomato fruits sold in the five different markets. The associated fungi were Aspergillus niger, Aspergillus ochraceous, Aspergillus flavus, Aspergillus fumigatus, Penicillium citrinum and Helminthosporim fulvum, Curvularia lunata and Sclerotium rolfsii. A. flavus and A. niger have the highest rate of occurrence among the isolated fungi, while S. rolfsii was the least encountered. Pathogenicity tests revealed that of all the isolated fungi, A. ochraceous, A. flavus, Sclerotium rolfsii and P. citrinum were highly pathogenic with the first three leading to rapid disintegration of treated fruits in 3‐5 days. A. niger was moderately pathogenic, while H. fulvum was least pathogenic on tomato fruits. Aflatoxins were detected from the sampled diseased‐marketed tomato fruits and also from the marketed rotten tomato fruits after autoclaving for 15 minutes at 121°C.

This study examined the impact of the Input Credit Scheme (ICS) by the Integrated Water Management and Agriculture Development (IWAD) on the productivity and food security of smallholder rice farmers in Ghana.

Cross-sectional data from 250 rice farming households in the Mamprugu Moagduri district of the North East Region obtained from a multi-stage sampling technique were used for the study. Inverse Probability Weighted Regression Adjustment (IPWRA), Propensity Score Matching (PSM) and Kendall's coefficient of concordance were the methods of analysis employed.

Empirical results show that education, rice farming experience, dependency ratio, FBO membership, farm size and farm age were the significant factors influencing participation in the input credit scheme (ICS). Also, participants had an average rice productivity of 1,476.83 kg/ha, whereas non-participants had 1,131.81 kg/ha implying that participants increased their productivity by about 30%. In addition, the study revealed that participant households increased their household dietary diversity (HDDS) by 0.45 points amounting to about 8% diversity in their diets. High-interest rates associated with credit received, the short periods of credit repayment and the high cost of inputs provided under the scheme were the most challenging constraints associated with partaking in the ICS.

The available literature on agricultural interventions have predominantly emphasized input credit as a key factor for improving cropt productivity and food security of smallholders. This study provides compelling evidence that participation in ICSs can result in substantial benefits for agricultural development, as evidenced by increased productivity leading to improved food security. The significance of these findings is highlighted by the fact that, through participation in input credit schemes, smallholder rice farmers in many developing countries see substantial improvement in their capacity to access productive resources, thereby improving their productivity, while simultaneously reducing food insecurity.

Leveraging on the improved productivity of participants in the ICS, this study advocates that such input credit schemes should scale up to more food-insecure farming communities in Ghana.

The study uses a doubly robust econometric approach to evaluate the impact of ICS on smallholder rice farmers' productivity and food security in Ghana, making it the first of its kind. The findings offer a solid basis for future research and provide guidance for policymakers looking to boost agricultural development in Ghana.

This study examines the association between emotional intelligence (EI) and the tendency of future accountants to rationalize and engage in occupational fraud.

The study adopts a survey methodology and uses a questionnaire containing a fraud scenario and EI construct to gather data from 225 participants. It performed a Cronbach alpha to assess the measurement parameters consistency of EI and fraud tendency and employed Pearson correlation and regression analysis to test its hypothesis.

The study found that future accountants in Nigeria are emotionally intelligent and have a high fraud tendency. Also, it found a significant and positive association between EI and fraud tendency, suggesting that future accountants that are emotionally intelligent have a higher tendency to rationalize and engage in occupational fraud. In addition, the study found that academic intelligence, a control variable, positively associates with fraud tendency.

The study offers rare insights into the fraud tendency of future accountants, which would benefit the counter fraud community in Nigeria and other developing countries. Recruiters and employers will find the study beneficial in decision-making on job recruitment, placements and moral orientation for prospective accountant employees.

The study is the first to directly associate EI with the fraud tendency of future accountants from a developing country with high fraud profile and underdeveloped counter fraud strategy. Thus, it provides a benchmark for future studies in other developing countries.

Cannabis as a recreational drug is prohibited in Nigeria. Consequently, the open use of cannabis attracts both formal and informal sanctions. As such, there is much stigma on users' faces across social spaces. This has led to innovations in drug use. Recently, non-medical use of tramadol has been rising across each of the gender categories. This study aims to understand (1) tramadol use prompts, (2) the sudden surge in gendered recreational use of tramadol and (3) the gendered challenges of recreational tramadol use among Nigerian university students.

Data were collected between December 2021 and October 2022. The researcher conducted 20 semi-structured interviews, with participants chosen purposefully from acquaintances and others selected through chain referral. The selection criteria included knowledge of a particular tramadol tablet and willingness to participate. This study got ethical approval from the Anambra State Ministry of Health (Ref: MH/AWK/M/321/354) and oral consent was obtained before the interviews. The participants were assured of confidentiality. The interviews were conducted in English (the formal Nigerian language) and lasted between 30 and 65 min. The data collected were transcribed and coded manually, and themes generated.

Findings suggest that peer pressures accounted for entry-level drug use. However, cannabis-related stigma is attributed to the surge in tramadol use across gender categories. Furthermore, academic pressure and sexuality are major reasons for tramadol use. The challenges associated with tramadol use include headaches and addiction.

This study, to the best of the author’s knowledge, presents alternative data on the surge in tramadol use among Nigerian university students.

The purpose of this study is to understand the complex interplay between illicit opioids trade and consumption practices and state policies that aim to reduce their misuse.

The study adopted an exploratory design. Data were gathered through in-depth interviews with 31 commercially oriented drug dealers in Uyo, Nigeria. The framework approach was used in data analyses, while “friction” provided the interpretive lens.

Accounts revealed public concerns over the misuse of tramadol and other opioids among young people and the associated health and social harms. These concerns provided support for enforcement-based approaches to prescription opioids control, including police raids on pharmacy stores. These measures did not curtail opioids supply and consumption. Instead, they constrained access to essential medicines for pain management, encouraged illegal markets and fuelled law enforcement corruption in the form of police complicity in illegal tramadol trade.

The findings reveal the frictions of drug control in Nigeria, wherein enforcement-based approaches gained traction through public concerns about opioids misuse but also faced resistance due to the persistence of non-medical use and illegal supply channels made possible by law enforcement complicity. These indicate a need to prioritize approaches that seek to reduce illegal supply and misuse of opioids while ensuring availability of these medications for health-care needs.

The study is unique in its focus on the creative tension that exists between state control measures and local opioids supply and consumption practices.

This paper aims to explore the role of tramadol in pain management and the impact of regulatory measures on supply and medical access in Ghana and other African countries.

The study adopted an exploratory design and qualitative methods to explore the perspectives of different actors, including officials of regulatory agencies, law enforcement agents, health-care providers and non-medical tramadol users. Data were collected through individual and group interviews, and transcripts were subjected to thematic analysis.

Findings show that tramadol fills a critical gap in treating pain across Ghana in areas with an acute shortage of opioid analgesics due to scheduling-related barriers. This was partly due to porous borders allowing for an influx of tramadol into the countries. The study further found that most tramadol purchases in Ghana and other West African countries were made from market traders rather than from health-care settings and were mainly generic medicines categorised as “substandard/spurious/falsely-labelled/falsified/counterfeit medical products” within the World Health Organization standards.

Although the findings are instructive, there were some limitations worth noting. The study encountered several limitations, especially with the non-medical users, because the environment is highly criminalised, People who use drugs were unwilling to avail themselves for fear of law enforcement officers’ harassment. Obtaining ethical clearance had its own bureaucracy – challenges that delayed the study time frame.

Placing tramadol under the list of internationally controlled substances would create barriers to access to effective pain medications, particularly by the poor, and encourage victimisation of users by law enforcement authorities.

The study is based on empirical research on tramadol use and regulation in African countries, contributing to knowledge in an under-researched subject area on the continent. The comparative approach further adds value to the research.

The purpose of this paper is to assess participants’ perception that tramadol enhances physical work performance and acts as a pain relief.

The participants were 30 (18 male and 12 female) tramadol-using emerging adults, aged 16–27 years, selected through respondent-driven sampling. The majority of the participants were university students, whereas others had completed senior secondary education. The study adopted a qualitative design. Qualitative data were analysed using thematic analyses.

In general, respondents perceived and used tramadol for pain relief and physical work performance enhancement. The result showed that sex, employment status and daily dosage were not associated with respondents’ perception of tramadol as a pain-relieving medication. In contrast, sex and employment status were associated with participants’ perception of tramadol as a physical work performance enhancement medication, but daily dosage was not.

Some users refused to participate because they were afraid of being exposed to law enforcement.

Male and female emerging adults are involved in non-medical use of tramadol. Prevention and intervention programs to reduce or stop this behaviour are needed, especially in the rural communities.

The result showed that users were mostly from poor homes, whose parents could not afford university education and who were not qualified to get good government paying jobs. So, the use of tramadol became necessary for them to make more money from the kind of jobs they did. Reduction of the cost of university education and provision of regular jobs for this population are some of the measures recommended to counter non-medical use of tramadol by this population.

This is the first study in South-eastern Nigeria that focused on the non-medical use of tramadol among emerging adults, using a qualitative design.

As e-commerce has expanded rapidly, online shopping platforms have become widespread in India and throughout the world. Product return, which has a negative effect on the E-Commerce Industry's economic and ecological sustainability, is one of the E-Commerce Industry's greatest challenges in light of the substantial increase in online transactions. The authors have analyzed the purchasing patterns of the customers to better comprehend their product purchase and return patterns.

The authors utilized digital transformation techniques-based recency, frequency and monetary models to better understand and segment potential customers in order to address personalized strategies to increase sales, and the authors performed seller clustering using k-means and hierarchical clustering to determine why some sellers have the most sales and what products they offer that entice customers to purchase.

The authors discovered, through the application of digital transformation models to customer segmentation, that over 61.15% of consumers are likely to purchase, loyal customers and utilize firm service, whereas approximately 35% of customers have either stopped purchasing or have relatively low spending. To retain these consumer segments, special consideration and an enticing offer are required. As the authors dug deeper into the seller clustering, we discovered that the maximum number of clusters is six, while certain clusters indicate that prompt delivery of the goods plays a crucial role in customer feedback and high sales volume.

This is one of the rare study that develops a seller segmentation strategy by utilizing digital transformation-based methods in order to achieve seller group division.

Analyses the alternative and informal remittance systems that characterise many Asian transactions; they are also known as informal value transfer systems, underground banking systems and so on: unlike money laundering, they are not based on deception and may indeed be licensed. Traces the origins of these systems, which are of two main types: the Chinese fei chi’en system and the Indian hawala/hundi system. Describes the two systems, and goes on to the reasons for their growing popularity: the increased migration of Asian populations to the rest of the world, the systems’ perceived efficiency, timeliness, cost effectiveness and lack of bureaucracy, the remoteness from banks of some areas, the desire of the Chinese to conceal wealth, and insufficient supply of foreign exchange in some countries.

Imbedded in the life course paradigm, the purpose of this paper is to investigate which individual life events impact blood donations and to study their underlying mechanisms.

By applying logistic regression, moderation and mediation analysis, this paper uses a large sample of N = 5,640 individuals.

Experiencing normative life events and stressful life events reduce the likelihood of donating blood, whereas human capital life events enhance the likelihood of donating blood. Specifically, having a child and death of a mother decrease and finishing education increases the probability of blood donations. Locus of control and satisfaction with income are significant underlying mechanisms.

Social marketing campaigns can use individual life events to focus on similarities between potential blood donors and individuals in need of blood. Blood centers can adopt their services to cater to the changing needs after experiencing individual life events by running mobile blood collecting drives and providing guidance.

Blood centers take an important role in sustaining a healthy society. As the need for blood will increase in the future, a better understanding of blood donation behavior and social marketing contributes to increased donations.

While previous research looked at collective life events, there is a dearth in marketing and blood literature on the effects of individual life events.
