To help address the problem of imperfections in the performance of cowpea markets in Ghana, the study sought to understand the costs and benefits associated with different market outlets and factors influencing farmers' choice of these outlets.

A two-stage sampling technique was adopted to collect data from 300 cowpea farmers through purposive sampling of communities and simple random selection at the farmer level in Ejura Sekyedumasi municipality of Ghana. Analytical methods including profitability measures such as gross margin, net margin, return on investment and multinomial logistic (MNL) regression model were used to analyze the data.

The results showed that production and marketing of cowpea is profitable with farmers who trade in wholesale markets recording the highest gross margin (Gh₵1245.85 (US$227.76)), net margin (Gh₵1029.37 (US$188.18)) and return on investment (ROI) of 63%. Important nonfarm-related factors including household size, farming experience, membership of farmer-based organization and extension contact were found to significantly influence the choice of marketing outlets in the study area. In addition, market attributes such as produce selling price, volume of cowpea sold and post-harvest value addition were also key determinants of cowpea market outlet choices.

The results of the study are vital to agricultural administrators in devising efficient cowpea market systems for smallholder farmers in Ghana. Likewise, the study provides important information to smallholder farmers in the choice of market outlets that maximizes their returns.

Previous studies on marketing of cowpea in Ghana emphasized on direct retail or consumer marketing to maximize farmers' returns. Meanwhile, there are claims to suggest that the sale of cowpea grains in the country are carried out through varied market outlets which come with differing costs and benefits implications for smallholder farmers. Therefore, the present study comprehensively compared associated costs and benefits in all available cowpea market outlets so as to settle the confusion surrounding most profitable and efficient marketing channel for smallholder farmers toward poverty reduction.

The objectives of this paper are to analyze the drivers of smoked marine fish prices and examine the challenges along the value chain to inform policy.

The study relies on cross-sectional data from 158 fish smokers, 100 wholesalers, and 120 retailers in Ghana. The challenges faced by the actors along the chain are identified and ranked using Kendall's coefficient of concordance. The three-stage least square estimation approach is employed to control for endogeneity resulting from the simultaneous equations for prices of different fish types and their substitutes.

The results reveal that marketing experience, the extent of competition, price of substitutes, payment terms, and variable cost items, such as transportation cost and storage charges, are key determinants of smoked fish prices along the value chain. Lack of access to credit is the main constraint to the marketing of smoked marine fish, irrespective of the actor or the fish type.

Many studies have established the linkages between fish consumption, prices, and food security in the literature. However, there is a dearth of information on the responsiveness of fish prices to changes in the market and seller-specific factors to drive policy to stabilize prices along the value chain.

The paper aims to examine impact of adopted maize seed technology on farm profitability. It assesses both the revenue and cost implication of the adopted technology on farmers' welfare. The study aims to expand the domain of farm investment assessment analysis by including a broader range of production outcome indicators than is normally found in the adoption impact on farm profitability literature.

The paper opted for an empirical study using field survey data. A structured questionnaire was used to interview 400 maize farmers across four regions of Ghana. The survey was complemented with focus group discussions in each region with participants representing male and female farmers cultivating maize on a commercial basis. The data captured detail household level (i.e. demographic and socioeconomic characteristics) as well as farm-level information on maize production (i.e. input use and farm output).

The paper provides empirical insights about maize farmers' perception on the adopted maize seed technology and the factors influencing adoption. It also shed light on the fact that maize farmers do not base their adoption decisions solely on farm output and revenue indicators alone, but mainly on the return on their investment and the cost associated with the maize seed technology adopted.

Because of data limitation, the influence of some important actors (market power) could not be directly captured in the analysis; this may lead to over simplification of a very complex situation in the maize sector. Therefore, researchers are encouraged to future investigate the influence of such important phenomenon on farm profitability.

Improving maize productivity and farm profitability across the sectors is important in order to improve farmer income. This study, therefore, highlights the effect of adopted seed technology and its impact on farm profitability.

This paper fulfils an identified need to study how investment cost in maize seed technology affect farm profitability.

The main purpose of this study was to assess constraints and determinants of pineapple farmers' choice of certification schemes in Ghana.

A multistage sampling method was used to solicit data from 345 pineapple farmers from Eastern and Central regions of Ghana. Analytical techniques including descriptive statistics, four-point Likert scale index and multinomial logistic regression model (MNL) were used to analyze the data.

The four-point scale index shows that high renewal fee for certification schemes is the most important constraint facing certified farmers before high labor cost of production. The MNL model shows that both off-farm income and age negatively influenced farmers' choice of GlobalG.A.P scheme. However, household size had significant positive influence on farmers' choice of GlobalG.A.P and Organic schemes. Likewise, formal education had significant positive relationship with the choice of Fairtrade and Organic certification schemes while farming experience positively influenced organic scheme choice. On the other hand, premium price and extension services positively influenced the likelihood of choosing all the three certification schemes. Lastly, regional dummy only negatively influences the choice of organic certification schemes.

This study contributes to the literature on certification schemes adopted by smallholder by analyzing the determinants and constraints of choice of scheme(s).

The study brings to bear the issues confronting smallholder pineapple farmers in the employment of certification schemes in developing countries, specifically Ghana.

The study analyzed the profitability of tomato farmers and determinants of farmers' choice of marketing outlets (wholesaler or retailer) in Ghana.

A two-stage sampling technique was used to collect data from 100 tomato farmers in Ghana. Analytical tools which include descriptive statistics, gross margin analysis (GM), profitability ratios and binary logit model were employed.

Profitability analysis indicates that farmers who supply to wholesalers have gross margin of Gh¢7.86 (US$1.67) per 25 kg crate, while farmers who supply to retailers recorded a major loss of Gh¢5.36 (US$1.14) per 25 kg crate. The result suggests that farmers selling to wholesalers are better off than farmers supplying to retailers. The binary logit regression analysis reveals a positive relationship between farmers' choice of marketing outlet (wholesaling) and age of respondents, quantity of tomato sold and cost of labor for production. A negative relationship also existed between farmers' choice of marketing outlet and weighted average selling price and household size.

The results call for policy efforts to provide an enabling environment for more extension education and establishment of farmer associations to make marketing information for price development among farmers available.

The choice of marketing outlet greatly influences profitability of tomato production. This study examines the performance of the various tomato marketing outlets in Ghana.

The purpose of this paper is to assess consumer motivation and willingness to pay (WTP) for “safer” vegetables from the use of non-treatment options of wastewater use in urban/peri-urban vegetable production.

As a theoretical basis, consumer theory of maximizing utility being an indicator of individual preference was examined through choice experiment (CE) method to measure the WTP for value of safety within the context of health reduced risk (pathogen reduction) of illness. WTP was tested empirically using survey data from 650 households in the two largest cities in Ghana (Accra and Kumasi) that are characterized by a number of well-established vegetable producers who use wastewater in their production and a large urban and peri-urban vegetable consumer market.

Experience of vegetable borne diseases drives the need for safer vegetables and income and gender are key demographic factors influencing WTP. It was further found that consumers are willing to pay an average amount of GH¢ 4.7 ($2.40) per month for a technology change that would result in the production of “safer” vegetables.

Understanding WTP offers insight into consumer concerns, behaviour and their readiness to pay for safer vegetable options. However, a further consideration of the impact of the combinations of the various non-treatment options on pathogen reduction and the assessment of the financial viability of each option will collectively ensure an efficient and cost-effective implementation of the technologies.

WTP insight gained has implications for vegetable production, marketing and public health policy. The understanding from the findings forms a solid basis to canvass for certification system for urban/peri urban vegetables. The information provided also helps to formulate effective public education on the safety of vegetables.

Measuring WTP for safer vegetables by Ghanaian urban/peri-urban consumers is novel. The CE approach is robust and the findings can inform vegetable production and marketing decisions as well as public health policy formulation.

This paper aims to determine the hierarchical relationship between building partnership competencies for public sector educational leaders (ELs) administering and running the education system.

An interpretive structural modelling (ISM) technique was used to develop a hierarchical structural model for building partnership competencies. Nominal group technique (NGT) was used with the help of experts’ suggestions and opinions at the beginning of ISM to identify building partnership competencies. Also, the NGT was used to rank the competencies. A structural self-integration matrix was developed based on experts’ voting and agreement. Cross-impact matrix multiplication applied to classification (MICMAC) analysis was used to analyse the relationship among the building partnership competencies. A total of 11 experts were chosen for NGT and ISM sessions.

A total of 16 building partnership competencies were identified for this study. The competencies were compartmentalised into four domains: creative collaboration, create network, develop collective culture and encouraging constructive dialogue. MICMAC analysis shows each domain of the model of its key competencies ranked at the highest level in the ISM model and dependent competencies.

ISM is a modelling approach that is based solely on expert opinions and responses. Its limitation can be overcome with the help of empirical analysis.

This study supports the public sector ELs’ professional development and upskilling. In addition, the model developed in the study will be helpful for stakeholders, human resources division and policymakers to incorporate building partnership competencies in the training and development of ELs.

This study helps to identify and prioritise building partnership competencies using NGT and ISM. Literature shows that numerous authors have used the ISM approach. Still, the combination of NGT approach is limited. Therefore, the model developed in the study was based solely on experts’ opinions and suggestion based on their experiences and knowledge.

The purpose of this paper is to examine the Malaysian National Professional Qualification for Educational Leaders (NPQEL), a principal leadership preparation programme and the Malaysian Education Blueprint 2013–2025, a comprehensive plan for a rapid and sustainable transformation of our education system through to 2025 to ensure high-performing school leaders in every school.

In understanding how the NPQEL operates and its effectiveness in preparing high performing school leaders, a research instrument of open-ended questions were administered to 102 principals from government-funded secondary schools, to establish how they were prepared for their leadership roles and their views of their leadership practices.

The NPQEL programme provides evidence of strong outcomes in preparing school leaders towards high-performing school leadership in Malaysia in combination of a variety of approaches with respect to its designs and competency standards. Findings indicate that the NPQEL contributes towards the development of the school leaders' attributes or skills for their leadership roles; and the NPQEL fulfils the aspirations set out in the Malaysian Education Blueprint 2013–2025.

This paper explores the potential influence of Malaysian NPQEL and the Malaysian Education Blueprint 2013–2025 on preparing high-performing school leaders in every school.

The purpose of this study is to explore mathematics teachers' collaboration within their professional learning communities (PLCs), and to gain insight into how the teachers developed their collective efficacy through it to focus on improving student learning.

Using a qualitative approach, data were collected from three high-performing secondary schools, mainly through semi-structured in-depth interviews with the Heads of Mathematics Unit. For explication and triangulation purposes, focus group interviews with the mathematics teachers and students and document analysis were also conducted.

The findings indicate that PLCs were the vessel through which a culture of disciplined teacher collaboration was fostered. More importantly, this culture encouraged teachers to participate in reflective dialogues that became a driver for their learning, and eventually led to their changed professional practice for improved student learning. The collaborative setting within the PLCs allowed teachers to pool their resources, knowledge and individual expertise to identify their student learning focus, and administer and measure their student intervention strategies. This collaborative professional learning reduced professional isolation, and as a result, improved teachers' collective pursuit of professional growth to impact student outcomes.

The aim of this qualitative study was to provide a detailed description of the teachers' collaboration within their PLCs based on the researchers' interpretation of how the participants make sense of their PLC practices and experiences. Hence, findings are indicative, and not definitive. In addition, the Heads of the Mathematics Unit, and the mathematics teacher participants in this study illustrated salient aspects of subject subcultures, where their beliefs, norms and practices were non-generic, or specific only to their subject context. Therefore, the implications to practice were built from commonalities shared only among the mathematics units.

This is a study in a Malaysian context that provides empirical evidences that are concerned primarily with the process of teachers developing their collective efficacy through disciplined collaboration within their PLCs.

The study aims to empirically analyze the effects of the presence of female top managers and owners on corporate tax compliance.

Data for analysis were sourced from the World Bank Enterprise Surveys that involved 23,178 private firms in 98 countries. The surveys used a stratified random sampling method by using three criteria, namely, firm size, business sector and geographic region, within each country. Further, data are analyzed using the ordinal logistic regression and supported by the marginal effect analysis.

The results show that the presence of female top managers and owners is a significant factor that underlies the firm-level tax compliance difference when firms exhibit relatively lower compliance.

Although this study shows that the determinants of corporate tax compliance are very complex, there are also crucial roles of top managers and owners' gender. This study advises firms to use the gender equality strategy to generate the best human capital, especially in their top management levels. Besides, this study can be helpful in designing policies that facilitate women to reach top managerial levels or to own businesses as an alternative method to enhance tax compliance for developing countries that fail to generate optimal corporate income tax revenues.

To the best of the authors’ knowledge, no previous studies examine the effects of the presence of female top managers and business owners on firms’ tax compliance policies. This study contributes to extend the understanding of the important role of women in corporate strategic decision-making, especially in taxation policies in various developing countries.
