Abstract
Purpose
The purpose of this paper is to test whether temporal aggregation matters when constructing hedonic house price indices for developing markets using Ghana as a case study.
Design/methodology/approach
Monthly, quarterly, semi-yearly and yearly hedonic price indices are constructed and six null hypotheses are tested using the F-ratios to examine the temporal aggregation effect.
Findings
The results show that temporal aggregation may not be a serious issue when constructing hedonic house price indices for developing markets as a result of the smaller sample size which these markets normally have. At even 10 per cent significance level, none of the F-ratios estimated is statistically significant. Analysis of the mean returns and volatilities reveal that indices constructed at the lower level of temporal aggregation are very volatile, suggesting that the volume of transactions can affect the level of temporal aggregation, and so, the temporal aggregation level should not be generalised, as is currently observed in the literature.
Originality/value
The diversification importance of real estate and the introduction of real estate derivatives and home equity insurance as financial products call for the construction of robust and accurate real estate indices in all markets. While almost all empirical research recommends real estate price indices to be conducted at the lower level of temporal aggregation, these studies are largely conducted in developed markets where transactions take place frequently and large transaction databases exist. Unfortunately, little is known about the importance of temporal aggregation effect when constructing indices for developing real estate markets. This paper contributes to fill these gaps.

Abstract
Purpose
The purpose of this paper is to empirically examine the relationship between lucky draw sales promotion (LDSP) and the four phases of brand loyalty in the telecommunication industry.
Design/methodology/approach
A self-administered structure questionnaire was used to collect primary data from conveniently sampled 338 lucky draw winners in the Ghanaian telecommunication industry. A response rate of 67.1 percent was obtained for data analysis using structural equation modeling approach.
Findings
It was found that LDSP positively relate to cognitive brand loyalty, and to behavioral brand loyalty through affective and conative brand loyalty. All hypothesized relationships among the sequential four-stage loyalty were confirmed, except the direct relationship between LDSP and behavioral brand loyalty.
Research limitations/implications
The findings are limited to lucky draw winners in the telecommunication industry.
Practical implications
Marketers can increase brand loyalty and profit more from their customers through targeted programs with hedonic benefits to build strong commitment level (conative brand loyalty), strong favoritism (affective brand loyalty) and strong beliefs about the superiority (cognitive brand loyalty) of a brand.
Originality/value
Theoretically, this study fills the void of empirical studies on non-price sales promotion techniques of lucky draw and customer brand loyalty in the telecommunication sector in developing economy context, and contributes to the body of knowledge in the area of customer brand loyalty and LDSP.

Abstract
Purpose
The purpose of this paper is to examine the role of marketing in the economic growth and competitive strategies of Sub-Sahara African firms. It also seeks to offer a backdrop for the papers in the present volume of AJEMS.
Design/methodology/approach
It is based on a review of a selection of literature that highlights past and current perspectives of marketing’s contribution to economic growth and firm performance in developing economies.
Findings
The review suggests that trade liberalization in African countries since the 1980s has changed the competitive landscape of firms located in these countries and has compelled them to develop market-oriented strategies in order to enhance their performance. But the strategies adopted tend to target the growing middle income segments of the population in the urban areas and to ignore the poor.
Originality/value
It provides directions for future research into issues of inclusive marketing policies and strategies – i.e. strategies that embrace the bottom of the pyramid and transforms the production base of African economies.

Abstract
Purpose
Inefficiencies in the power sector resulting from underinvesting and underselling reduce the ability of governments to adequately finance energy projects. The purpose of this paper is to explore mechanisms of energy financing, benefits and challenges associated with innovative financing of energy infrastructure as well as strategies to improve innovative financing of energy infrastructure.
Design/methodology/approach
Questionnaires were used to elicit responses from respondents. Seventy-eight responses were retrieved. Mean score ranking, Kruskal–Wallis test and discriminant validity were the analysis conducted.
Findings
Partial credit guarantee; partial risk guarantee; credit enhancement; and loan guarantees were the significant mechanisms. Production efficiency; reduce pressure on public budgets; access to management expertise; and self-sustainability of infrastructure facilities were the significant benefits. Lack of transparency and adequate data for risk assessment; high up-front cost; heterogeneity, complexity, and presence of a large number of parties; and lack of a clear benchmark for measuring investment performance were the severest challenges. Complete transparency and accountability; political stability and public view on private provision of energy infrastructure services; and macroeconomic environment were the significant strategies.
Practical implications
This study is beneficial to energy sector as the current government of Ghana hints on willingness to involve private sector in management of the power sector.
Originality/value
The novelty of this study is that it is a pioneering study in Ghana on innovative financing of energy infrastructure.

Abstract
Purpose
The demand for energy infrastructure projects has increased steadily over the last few decades and has come at a high cost. Disruptive technologies (DTs) have the inherent capability to affect the performance of energy infrastructure projects. Therefore, this research aims to explore the implications of DTs on the performance of energy infrastructure projects.
Design/methodology/approach
This research adopts a positivist philosophical position. A quantitative strategy and deductive approach (based on a survey design) guided this study. Sixty-six respondents participated in the study. The study’s population comprised of experts in energy infrastructure projects who possessed a high level of industrial experience including top- and middle-level management of power generation companies. Cochran’s formula was used to select a sufficient sample for the study. Linear regression, one sample test and Cronbach’s alpha were the analytical tools adopted.
Findings
This study established that there is an 18.4% increase in the performance of energy infrastructure projects in Ghana when DTs are applied. In order of importance, DTs improve speed of operations in energy projects; reduce operating cost and enhance efficiency of energy projects; drive sustainable economic development; enhance security in energy projects; and improve environmental sustainability of projects. The study also revealed that e-commerce technologies, renewable energy technologies, three-dimensional printing, bar code technology, photogrammetry, global positioning systems, geographic information systems and nanotechnologies were the topmost ranked DTs with the most impact on the performance of energy infrastructure projects.
Originality/value
This is a novel investigation on the implications of DTs on the performance of Ghanaian energy infrastructure projects. This study’s practical implication is evident in both policy and practice. Energy sector policymakers should endeavour to adopt DTs in their operations to enhance sustainability and performance.

Abstract
Purpose
The purpose of this paper is to examine the spatial patterns of gender inequality in junior high school enrollment and the educational resource investments associated with the spatial trends.
Design/methodology/approach
The paper uses data on 170 districts in Ghana and hot spot analysis based on the Getis-Ord Gi statistic, linear regression, and geographically weighted regression to assess spatial variability in gender parity in junior high school enrollment and its association with resource allocation.
Findings
The results reveal rural-urban and north-south variability in gender parity. Results show that educational resources contribute to gender parity. At the national level, educational expenditure, and the number of classrooms, teachers, and available writing places have the strongest positive associations with girls’ enrollment. These relationships are spatially moderated, such that predominantly rural and Northern districts experience the most substantial benefits of educational investments.
Practical implications
The findings show that strategic allocation of infrastructure, financial, and human resources through local governments holds promise for a more impactful and sustainable educational development of all children, regardless of gender. Besides seeking solutions that address the lack of resources at the national level, there is a need for locally tailored efforts to remove the barriers to equitable distribution of educational resources across gender and socioeconomic groups.
Originality/value
This paper’s use of advanced spatial analysis techniques allows for in-depth examination of gender parity and investments in educational resources, and highlights the spatial nuances in how such investments predict gender disparities in junior high school enrollment. The findings speak to the need for targeted and localized efforts to address gender and geographical disparities in educational opportunities.

Abstract
This chapter seeks to help and support online educators in their efforts to improve tomorrow. Specifically, the chapter shares practical strategies and tools that online educators can easily apply, adapt, and/or personalize in order to help promote a mindfully multicultural classroom in their online classrooms and programs. The chapter includes a wide range of actionable tools and exercises to help online instructors optimize the learning experience for all students by building upon the unique strengths and diverse cultural backgrounds of all students in their online classrooms. The strategies help instructors leverage diversity as a means to promote equity and social justice in online programs and, ultimately, the world as a whole. The chapter relies upon Gollnick and Chinn’s (2017) six beliefs that are fundamental to multicultural education and presents strategies from two perspectives or lenses (student-focused and faculty-focused). Approaching the issue from a dual-sided lens is intended to best support the ultimate goal of improving the student learning experience. Emphasis is placed on both public and private interactions between faculty and students. Public interactions include all discussion board and announcement communications. Public interactions also include resources that are shared in the online classroom for all students’ benefit.

Abstract
In spite of the growing evidence of intimate partner violence (IPV) against men, limited scholarly work exists on this topic. To date, few studies have explored the motivations and socio-cultural underpinnings of violence against men in Kenya and sub-Saharan Africa in general. Using the Kenya Demographic and Health Survey and employing logit models, we examined associations between women's controlling behaviours and IPV among 3,262 Kenyan men aged 15–54 years. Over 60% of the Kenyan men surveyed reported their female partners were controlling. Compared with those who did not, men who reported controlling behaviours were significantly more likely to have experienced three types of violence (physical, sexual and emotional). Educated Kenyan men had higher odds of experiencing physical and emotional violence than the uneducated, and they reported higher levels of control by their female partners. Our findings suggest that IPV against men may be goal-oriented, but there is also evidence that it may be a reaction to male-perpetrated abuse.

Abstract
Background: Geostatistics focuses on spatial or spatiotemporal datasets. Geostatistics was initially developed to generate probability distribution predictions of ore grade in the mining industry; however, it has been successfully applied in diverse scientific disciplines. This technique includes univariate, multivariate, and simulations. Kriging geostatistical methods, simple, ordinary, and universal Kriging, are not multivariate models in the usual statistical function. Notwithstanding, simple, ordinary, and universal kriging techniques utilize random function models that include unlimited random variables while modeling one attribute. The coKriging technique is a multivariate estimation method that simultaneously models two or more attributes defined with the same domains as coregionalization.
Objective: This study investigates the impact of populations on traffic volumes as a variable. The additional variable determines the strength or accuracy obtained when data integration is adopted. In addition, this is to help improve the estimation of annual average daily traffic (AADT).
Methods procedures, process: The investigation adopts the coKriging technique with AADT data from 2009 to 2016 from Montana, Minnesota, and Washington as primary attributes and population as a controlling factor (second variable). CK is implemented for this study after reviewing the literature and work completed by comparing it with other geostatistical methods.
Results, observations, and conclusions: The Investigation employed two variables. The data integration methods employed in CK yield more reliable models because their strength is drawn from multiple variables. The cross-validation results of the model types explored with the CK technique successfully evaluate the interpolation technique's performance and help select optimal models for each state. The results from Montana and Minnesota models accurately represent the states' traffic and population density. The Washington model had a few exceptions. However, the secondary attribute helped yield an accurate interpretation. Consequently, the impact of tourism, shopping, recreation centers, and possible transiting patterns throughout the state is worth exploring.
