Abstract
The etiology of fruit anthracnose in hot pepper (Capsicum frutescens) was investigated at Ibadan, Osogbo, and Ikenne in the lowland forest zone of western Nigeria. Collectotrichum capsici (Synd) Butler & Bisby was found associated with the fruit anthracnose of hot pepper in all locations. Out of 300 plants examined in all the locations, over 70 per cent had fruit anthracnose, while in some pepper fields all the fruits produced had the disease symptom. The pathogen overseasoned in pepper plant debris. A high inoculum population of 4.9×106 g−1 colony forming units/g was estimated in the soil of pepper fields. The seed from the infected hot pepper fruits also carried propergules of the pathogen. The fungus was also found on Lycopersicon esculentus, C. annum and Vigna unguiculata growing in and around the pepper fields. Pepper fruits infection by the disease occurs during the peak of the rainy season beginning in patches which spread later, resulting in extensive infection of the pepper field.

Abstract
Purpose
A correlation has been shown in the literature between credit constraints and the adoption of agricultural technologies, technical efficiencies and measures for adapting to climate change. The relationship between credit constraints, risk management strategy adoption and income, however, is not well understood. Consequently, the purpose of this study was to investigate how credit constraints affect the income and risk management practices adopted by Northern Nigerian maize farmers.
Design/methodology/approach
Cross-sectional data were collected from 300 maize farmers in Northern Nigeria using a multi-stage sampling technique. Descriptive statistics, seemingly unrelated regression and double hurdle regression models were the analysis methods.
Findings
The results showed that friends and relatives, banks, “Adashe”, cooperatives and farmer groups were the main sources of credit in the study area. The findings also revealed that the sources of risk in the study area included production risk, economic risk, financial risk, institutional risk, technological risk and human risk. In addition, the risk management strategies used to mitigate observed risks were fertilizer application, insecticides, planting of disease-resistant varieties, use of herbicides, practising mixed cropping, modern planning, use of management tools as well as making bunds and channels. Furthermore, we found that interest rate, farm size, level of education, gender and marital status were significant determinants of statuses of credit constraints while the age of the farmer, gender, household size, primary occupation, access to extension services and income from maize production affected the choice and intensity of adoption of risk management strategies among the farmers.
Research limitations/implications
The study concluded that credit constrained status condition of farmers negatively affected the adoption of some risk management strategies and maize farmers’ income.
Practical implications
The study concluded that credit constrained status condition of farmers negatively affected the adoption of some risk management strategies and maize farmers’ income. It therefore recommends that financial service providers should be engaged to design financial products that are tailored to the needs of smallholder farmers in the study area.
Originality/value
This paper incorporates the role of constraints in influencing farmers’ decisions to uptake credits and subsequently their adoption behaviours on risk management strategies. The researcher approached the topic with a state-of-the-art method which allows for obtaining more reliable results and hence more specific contributions to research and practice.

Abstract
Purpose
Given the reality that working mothers experience difficulties in achieving work-family balance because of the social restrictions that arise from parenting combined with career goals, this paper aims to explore the various coping strategies that are used by working mothers in the cities of London (Great Britain) and Lagos (Nigeria).
Design/methodology/approach
Semi-structured interviews were conducted with 72 mothers who worked in banks in London (Great Britain) and Lagos (Nigeria). Thematic analysis and investigator triangulation are used.
Findings
The findings reveal various coping strategies used by working mothers in the cities of Lagos and London. The paper also unearths the efficiency and the shortcomings of the use of au pairs among British working mothers and the similarities and disparities in terms of such use compared to the traditional use of housekeepers in Nigeria.
Originality/value
This paper contributes to the existing work–family balance literature by exploring the coping strategies of working mothers because of sociocultural and institutional differences in Great Britain and Nigeria.

Abstract
Purpose
Although employees' creativity is vital for firm innovation and overall performance, little is done to examine the potential association between creativity and employment. This paper investigates the contribution of employees' creativity, process and product innovations to firm-level employment growth.
Design/methodology/approach
The authors use data from World Bank Enterprise Survey and Innovation Follow-up Survey on 9503 firms covering the period 2012–2015 in 11 countries from sub-Saharan Africa and Heckman's two-stage estimation model.
Findings
This study's results indicate a positive role of creativity on firm-level employment growth. In addition, the authors find evidence for a complementary effect arising from the combination of creativity with managerial experience, staff level of education and their associated skills, in contrast, combining creativity with internal or external R&D results in a substitution effect. Interestingly, these synergy effects are pronounced for SMEs but absent for large firms.
Practical implications
Policy makers in developing economies of sub-Saharan Africa should stimulate company management to use free time offered to employees to be creative in the workplace as one of their key strategies to stimulate employment growth. This strategy is expected to be particularly fruitful among SMEs having some managerial experience and skilled stuff.
Originality/value
In contribution to innovative work practices and workforce creativity, the authors demonstrate that providing employees with free time could be an alternative way to enhance the focal firms' performance.

Abstract
Purpose
Fresh fruits and vegetables (FV) are crucial global food resources, but the presence of heat loads during harvest adversely impacts their shelf life. While freezing technology provides an effective means of removing heat loads, it is an energy-intensive process and may consequently prove too costly for practical business viability. The growing interest in utilizing magnetic field (MF) technology during the freezing of fresh FV enhances the freezing rate and rapidly removes the heat loads of products.
Design/methodology/approach
In the present study, pulsed magnetic field (PMF) pretreatment employing specific field strengths (9 T, 14 T and 20 T) was examined as a preliminary step before freezing mango and tomato and compared to the conventional freezing method (untreated) at − 18 °C.
Findings
PMF pretreatment prior to freezing demonstrated a noteworthy enhancement in freezing rate by around 10 and 12% when compared with the conventional (untreated) freezing, which exhibited freezing rates of −0.08 °C/min and −1.10 °C/min for mango and tomato, respectively. The PMF pretreatment (at 20 T) provided a higher freezing rate (at p = 0.05) than the conventional freezing method reduced heat loads amounting to 1.1 × 107 J/kg oC and 2.9 × 106 J/kg oC, significantly (at p = 0.05) from mango and tomato, respectively. These reductions in heat loads were approximately more than 5% of the calculated heat loads removed during conventional freezing.
Research limitations/implications
Mango and tomato samples were only tested; the results may lack generalizability. Therefore, researchers are encouraged to test for other products for further studies.
Practical implications
The paper includes implications for the development of a rapid freezing technique, the development of “pulsed magnetic field” and for eliminating the problem associated with conventional (slow) freezing.
Originality/value
The study holds significance for the production of postharvest freezing technology, providing insightful information on the PMF-assisted freezing of cellular foods.

Abstract
Purpose
The significant impact of innovation in stimulating economic growth cannot be overemphasized, more importantly from policy perspective. For this reason, the relationship between innovation and economic growth in developing economies such as the ones in Africa has remained topical. Yet, innovation as a concept is multi-dimensional and cannot be measured by just one single variable. With hindsight of the traditional measures of innovation in literature, we augment it with the number of scientific journals published in the region to enrich this discourse.
Design/methodology/approach
We focus on an approach that explores innovation policy qualitatively from various policy documents of selected countries in the region from three policy perspectives (i.e. institutional framework, financing and diffusion and interaction). We further investigate whether innovation as perceived differently is important for economic growth in 25 economies in sub-Saharan Africa over the period 1990–2016. Instrumental variable estimation of a threshold regression is used to capture the contributions of innovation as a multi-dimensional concept on economic growth, while dealing with endogeneity between the regressors and error term.
Findings
The results from both traditional panel regressions and IV panel threshold regressions show a positive relationship between innovation and economic growth, although the impact seems negligible. Institutional quality dampens innovation among low-regime economies, and the relation is persistent regardless of when the focus is on aggregate or decomposed institutional factors. The impact of innovation on economic growth in most regressions is robust to different dimensions of innovation. Yet, the coefficients of the innovation variables in the two regimes are quite dissimilar. While most countries in the region have offered financial support in the form of budgetary allocations to strengthen institutions, barriers to the design and implementation of innovation policies may be responsible for the sluggish contribution of innovation to the growth pattern of the region.
Originality/value
Segregating economies of Africa into two distinct regimes based on a threshold of investment in education as a share of GDP in order to understand the relationship between innovation and economic growth is quite novel. This lends credence to the fact that innovation as a multifaceted concept does not take place by chance – it is carefully planned. We have enriched the discourse of innovation and thus helped in deepening understanding on this contentious subject.

Abstract
Purpose
The combination of different knowledge sources has been considered conducive for innovation performance. While the literature has advanced regarding the combination of knowledge inputs as in internal and external research and development (R&D), the evolvement of knowledge blend from customers and competitors has also received substantial attention. The purpose of this paper is to delineate the sources of information from the customers into private and public and examine their direct effect on firm-level innovation. While the extant literature is mixed regarding this, no clear-cut results have emerged yet on the effect of knowledge combination from the private and public customers with internal R&D and human capital on innovation activities. This study, however, shed more lights on the inconclusiveness of the effect of knowledge diversity on firm-level innovation.
Design/methodology/approach
Using the microdata from the German Community Innovation Survey 2013, the authors employ a binary instrumental variable treatment model with Heckman selection, a suitable strategy to estimate binary variables to cope with a possible endogeneity issue.
Findings
The paper demonstrates that knowledge from customers in the private and public sector, and competitors are positively and significantly associated with innovation. The authors find evidence of a positive and significant effect of the combination of firm internal knowledge competencies with information from the public sector. In contrary, the blend of knowledge competencies with information from customers in the private sector and information from the competitors results in decline to innovation. The results also show that the blend of internal R&D with knowledge source from the customers in the public sector appears to have a stronger influence in the manufacturing sector than services. The results offer strong evidence of the positive link between knowledge diversity and firm-level innovation performance.
Practical implications
The results have significant managerial implications on the role of the blend of different sources of information in supporting a compelling internal knowledge development to optimise innovation performance.
Originality/value
This study is foremost to focus on knowledge sources from the customers in the public and private sector and its relationship with R&D and human capital in supporting a successful introduction of innovation.

Abstract
Purpose
The purpose of this study is to propose and explore a conceptualization of decisional capital that is suitable for early career teachers.
Design/methodology/approach
This study uses exploratory factor analysis on a sample of early career teachers to examine a literature-derived conceptualization of decisional capital.
Findings
The factors that emerged support the literature-derived conceptualization. A subsequent confirmatory factor analysis on a second sample of early career teachers offers additional evidence for the proposed conceptualization. An exploration of the underlying factor structure comparing results across four competing models (i.e. unidimensional, correlated factors, second order, and bifactor) suggests that a second order factor explains the variance across the three proposed factors well. We conclude that this second order factor is decisional capital.
Originality/value
This is the first study that examines the discrete elements of decisional capital. Understanding these discrete elements is an avenue for investigation into the development of decisional capital beyond the acknowledgment that it takes time to develop.

Abstract
Purpose
There is little to no empirical research on the phenomenon of ways in which the racism of whiteness transpires within the faculties and classrooms of US-based ALA-accredited library and information science (LIS) education programs. We do have scholars publishing meaningful work exploring diversity-equity-inclusion topics and initiatives to evolve the LIS discourse on these issues (Honma, 2005; Chancellor, 2019; De LaRosa et al., 2021; Gibson, 2019; Mehra et al., 2023; Colón-Aguirre et al., 2022; Hands, 2022). This research substantiates the conceptual research that exists by empirically exposing the ways in which the racism of whiteness functions at the interpersonal level of work culture in LIS programs (i.e. the academy) in the US.
Design/methodology/approach
Adapting Baima and Sude’s (2020) modified Delphi Method, a focus group of 13 BIPOC (Black, Indigenous, and People of Color) library and information science faculty members in the United States were recruited to participate in a one-time 60-min virtual Zoom session. Participants were engaged in three iterative rounds of reflective inquiry to reach a consensus of experience. The study design was embedded with critical race theory-based (CRT) ethnographic methods such as testimony (counterstorytelling), collective affirmation (shared narratives), and silence.
Findings
BIPOC LIS faculty (tenure-track and tenured) have similar ideas about whiteness and how it is operationalized as micro- and macro-aggressions in the LIS academic workplace, most significantly inside the classroom. The experience of whiteness was prevalent among all study participants in two areas: workplace meetings with faculty colleagues and classroom sessions (face-to-face and online) with students.
Originality/value
The findings offer empirical evidence to support the prolific conceptual literature in LIS discourse concerning ways in which critical race theory (CRT) interrogates LIS’s socio-professional injustices and inequities (e.g. Gibson et al., 2018; Stauffer, 2020; Leung and Lopez-McKnight, 2021; Jennings and Kinzer, 2022; Snow and Dunbar, 2022). There remains a dearth of empirical research that reports how whiteness is reproduced in the practices, knowledge, and resources that make up the ethos of the LIS faculty meeting and classroom. Documenting the testimonies of BIPOC LIS faculty solidifies the existence of whiteness as a toxic reality in the LIS academy.

Abstract
Purpose
Despite a reduction in poverty the global population in 2015, the incidence of poverty remains very high in Sub-Saharan African countries. Most of the countries in the region are agrarian, with most of their population residing in rural areas, and a majority of the poor in the region are found in Nigeria. This study examined the nexus between participation in nonfarm enterprises (NFEs) and poverty among rural farm households in Nigeria and across the six geopolitical zones.
Design/methodology/approach
The Nigerian Living Standard Survey (NLSS) conducted in 2018–2019 by the National Bureau of Statistics was used. We made use of 13,440 farm households with useful information for the purpose of this study. The sample comprises 6,885 households that participated in NFEs and 6,555 nonparticipating households. The data were analyzed with Foster, Greer, and Thorbecke (FGT) (1984) metrics, probit, and fractional probit models at p = 0.05.
Findings
The incidence of poverty was lower among the participating households than in the nonparticipating households. Participation in NFEs had a mitigating effect on poverty. We also established that zonal differentials in poverty rates exist among households in all the analyses. Participation in NFEs was influenced by individual, household, and institutional factors and was also able to explain the depth of poverty among the respondents.
Practical implications
It is suggested that poverty alleviation policies should be targeted at improving access to nonfarm economic activities by rural farm households residing in vulnerable geopolitical zones.
Originality/value
This study is the first attempt to profile household poverty based on the type of NFEs they are involved in. The study also provides an insight into the effect of the state of residence on zonal poverty models, which is expedient if the country must achieve Sustainable Development Goal 1 on the eradication of poverty everywhere.
