This paper seeks to describe the use of edge‐detection as an approach to support the process of analyzing visual scenes.

Edges‐detection is considered as a KM technique task. Several edge‐detection algorithms were discussed but Canny method was chosen in conjunction with JAVA to find the edges of an image.

The paper provides an overview of knowledge need by the visual scene analyst. It reviews the process of extracting knowledge from image data. Finally, the paper looks at the management aspects of image‐edge detection.

Experiments herein have proved the method robustness by considering edge‐detection as a knowledge management technique for visual scene analysis by deriving knowledge from semantic information based on object boundaries shadow.

The purpose of this paper is to suggest a conceptual analysis and design of knowledge management (KM) system for “Ifa” divination. In previous research, a randomized expert system for “Ifa” was proposed. In the system, the signatures of the divine‐chain are simulated through randomization process from 1 to 16, triggering the inference engine and knowledge base. This system has been experimented and it works.

The paper proposes a conceptual analysis and design of KM system for “Ifa.” In this system, applying KM to “Ifa” oracle consultation plays the core role. Moreover, the formal explanation of the whole process is given.

“Ifa” knowledge visualization was designed with Visual Basic 6.0 and MS‐Access for storing “Ifa” data. The paper presents an application tagged “Ifagraph” – an oracle browser version 1.0.0 that displays the signatures when executed.

This is a novel approach that promotes indigenous technology from an African perspective.

Today, many countries strive to develop their small and medium scale enterprises (SMEs) sectors because of their acknowledged capacity to facilitate the optimal utilization of locally available resources while engaging local technology for the production of goods and services for local consumption as well as export trade. Also in area of agriculture, these enterprises serve as means of sustainable food production, improve employment generation, combat food shortage, and enhance economic growth and development. However, the growth performance of this sector in Nigeria has been dwindling over time, which requires government expenditure (GE) policy intervention. Therefore, this study examines the influence of public expenditure on the growth of SMEs in Nigeria employing unit root and co-integration tests for the period 1981–2019. The results reveal that SMEs and selected macroeconomic variables have a long-run relationship with SMEs output performance. It also shows that GE has direct and significant impact on the growth of SMEs in Nigeria, while government deficit financing (GDF) has adverse and insignificant effects on the Nigeria SMEs both in the short- and long-run period. Inflation rate (INF) has an inverse but significant effect on the growth of SMEs in Nigeria both in the short- and long-run periods. This study thus recommends, among others, that government should ensure the proper management of capital expenditure and recurrent expenditure in raising the growth of SMEs in Nigeria to achieve inclusive growth.

The purpose of the paper was to analyze the financial risk perception of owners/managers and to link such perception to the performance of their ventures.

The paper employed PLS-SEM to analyze financial risks and its impact on SMEs in the food processing sector. Financial risks data on the operational, market, technological, credit and liquidity risks and financial performance including compliance, social and resource efficiency performance were collected from 214 food processors in selected cities in Ghana. Higher-order constructs were employed in assessing the relationship between financial risks and SME performance.

Financial risk spurs a firm's financial performance. Increased financial risks cause firms to be resource-efficient and compliant. Furthermore, an assessment of how the various performance indicators interplay showed increased compliant improved social performance and vice versa.

The paper looked at food processing firms in three major cities, analyzing the financial risks of the businesses and their effect on their performance. Although, these cities have the largest number of these firms, generalizing the findings from the study should be done taking into consideration the scope of the study.

The study exposes owners/managers to the critical issues of financial risk, its components and how this could impact on their operations. It expected that owner/managers in the food processing sector would craft the necessary risk mitigating strategies to deal with the different financial risks they face. For theoretical implication, the paper suggests the need to highlight the risk exposure of firms due to the business–stakeholder interactions as contained in the stakeholder theory.

The paper employed the higher-order construct of PLS-SEM to analyze the financial risks of food processors. The originality of the paper lies with the methods used.

This study is an exploratory study investigating firm-specific internal factors that influence the profitability performance of selected life insurance firms in eight Asian countries (China, Hong Kong, Taiwan, Singapore, Japan, South Korea, Thailand and Malaysia) from 2008-2014. This paper aims to focus on internal rather than external factors based on the resource-based view suggesting that the internal resources of a firm are key to gaining competitive advantage.

The authors used panel data estimation model to test our six hypotheses on these eight selected countries for the period between 2008 and 2014.

A random effect model reveals that size, volume of capital and underwriting risk are significantly related to the profitability of Asian life insurance firm, measured as return on assets. Premium growth, asset tangibility and liquidity are insignificant predictors of the profitability performance of these life insurance firms.

Three implications of this study are that life insurance firms need to proactively tap new business opportunities by attracting younger generation customers via e-marketing technologies; secure larger capital base to finance their market expansion strategies; and focus on intangible resources such as goodwill, brand equity and reputation.

This study contributes to the literature by conducting an exploratory regional-based panel study of Asian life insurance firms to find common factors that contribute towards profitability. The study is conducted on a collective sample of Asian life insurance firms based on the premise that the firms included in the sample engage in cross-border activities and share the same international financial reporting standards. These commonalities allow us to treat the firms jointly in a somewhat similar Asian macroeconomic environment.

Manufacturing and services SMEs in Africa face challenges and constraints exacerbated by ineffectual government policies, environmental turbulence and the near absence of institutional support. The purpose of this paper is to investigate if informal linkages and formal cooperation are helping firms to overcome constraints to uptake of technological innovations in Nigeria.

The paper is based on quantitative data obtained from structured interviews of 631 Nigerian firms. These firms were selected using stratified random sampling from a total population of 18,906 manufacturing and services companies in the national database obtained from the National Bureau of Statistics.

The result of the binary logistic regression indicates that while informal linkages appear to be insignificant, formal inter-firm cooperation is an effective moderator of barriers to technological innovations.

The paper focusses only on technological, rather than non-technological, innovations.

The paper recommends that, in addition to other interventions to promote diffusion of technological innovations, governments should give priority to interventions that support formal cooperation among SMEs.

Previous studies have generally looked at the impact of cooperative networks on firms’ innovation uptake. This paper provides original insights into the “how” of cooperative impact, specifically with respect to helping SMEs to overcome constraints. The paper also delineates formal cooperation from informal linkages.

A mathematical model and numerical method for water flow and solute transport in a tidal river network is presented. The tidal river network is defined as a system of open channels or rivers with junctions and cross sections. As an example, the Pearl River in China is represented by a network of 104 channels, 62 nodes, and a total of 330 cross sections with 11 boundary sections for one of the applications. The simulations are performed with a supercomputer for seven scenarios of water flow and/or solute transport in the Pearl River, China, with different hydrological and weather conditions. Comparisons with available data are shown. The intention of this study is to summarize previous works and to provide a useful tool for water environmental management in a tidal river network, particularly for the Pearl River, China.

This study aims to present a step-by-step implementation of the culturo–techno-contextual approach (CTCA) in a university classroom to teach industry and competitive analysis in the Ghanaian undergraduate entrepreneurship development curriculum. It further investigates the efficacy of the CTCA in breaking difficulties related to the study of industry and competitive analysis as a difficult concept in the Ghanaian entrepreneurship development curriculum. In doing this, the CTCA is compared with the lecture method.

The study adopts a quantitative approach. A quasi-experimental design is employed to gather data from 215 level 400 (4th-year undergraduate students) entrepreneurship development students at a Ghanaian public university. The experimental group was taught with CTCA, while the control group used the lecture method. The data was collected using the industry and competitive analysis achievement test (ICAAT). As random assignment to experimental and control groups were not possible, the data were subjected to an analysis of covariance approach with pre-test scores added as a covariate.

The results show that the experimental group significantly outperformed the control group. The results further indicate the efficacy of CTCA in improving undergraduate students’ performance in complex concepts of entrepreneurship.

Researchers usually test alternative teaching methods to break down barriers to study difficulties. The study’s uniqueness stems from the CTCA’s ground-breaking application to the study of entrepreneurship development in a Ghanaian public university.

The lecture method has been compared with teaching methods such as flip learning, cooperative learning and simulations to establish which holds the key to students' understanding of concepts. What is bereft in the education literature is its comparative efficiency with the culturo-techno contextual approach (CTCA) in the teaching of computer science education.

This study adopted the quasi-experimental design to determine the efficacy of the CTCA in breaking difficulties related to the study of spreadsheets as a difficult concept in the Nigerian computer science education curriculum. Junior high school students studying computer science education participated in the study. The control group had 30 students, with 35 students in the experimental group. The experimental group was taught using CTCA, while the control group used the lecture method. The spread sheet achievement test, which had 40 items on spreadsheet, was used to collect data.

The results showed that the experimental group significantly outperformed the control group [F (1,60) = 41.89; p < 0.05]. The findings showed the potential of CTCA in improving students' performance in spreadsheets in the computer science education curriculum.

The originality of this study is hinged on its ground-breaking test of the CTCA to the study of the spreadsheet. The findings of this study indicate its efficacy in improving students' understanding of spreadsheet and computer science education.
