This study examines the roles of cross-sectional dependence, asymmetric structure and country-to-country policy variations in the inflation-poverty reduction causal nexus in selected sub-Saharan African (SSA) countries from 1981 to 2019.

To account for cross-sectional dependence, heterogeneity and policy variations across countries in the inflation-poverty reduction causal nexus, this study uses robust Hatemi-J data decomposition procedures and a battery of second-generation techniques. These techniques include cross-sectional dependency tests, panel unit root tests, slope homogeneity tests and the Dumitrescu-Hurlin panel Granger non-causality approach.

Unlike existing studies, the panel and country-specific findings exhibit several dimensions of asymmetric causality in the inflation-poverty nexus. Positive inflationary shocks Granger-causes poverty reduction through investment and employment opportunities that benefit the impoverished in SSA. These findings align with country-specific analyses of Botswana, Cameroon, Gabon, Mauritania, South Africa and Togo. Also, a decline in poverty causes inflation to increase in the Congo Republic, Madagascar, Nigeria, Senegal and Togo. All panel and country-specific analyses reveal at least one dimension of asymmetric causality or another.

All stakeholders and policymakers must pay adequate attention to issues of asymmetric structures, nonlinearities and country-to-country policy variations to address country-specific issues and the socioeconomic problems in the probable causal nexus between the high incidence of extreme poverty and double-digit inflation rates in most SSA countries.

Studies on the inflation-poverty nexus are not uncommon in economic literature. Most existing studies focus on inflation’s effect on poverty. Existing studies that examine the inflation-poverty causal relationship covertly assume no asymmetric structure and nonlinearity. Also, the issues of cross-sectional dependence and heterogeneity are unexplored in the causal link in existing studies. All panel studies covertly impose homogeneous policies on countries in the causality. This study relaxes this supposition by allowing policies to vary across countries in the panel framework. Thus, this study makes three-dimensional contributions to increasing understanding of the inflation-poverty nexus.

The lack of a definite standard for determining the sample size in qualitative research leaves the research process to the initiative of the researcher, and this situation overshadows the scientificity of the research. The primary purpose of this research is to propose a model by questioning the problem of determining the sample size, which is one of the essential issues in qualitative research. The fuzzy logic model is proposed to determine the sample size in qualitative research.

Considering the structure of the problem in the present study, the proposed fuzzy logic model will benefit and contribute to the literature and practical applications. In this context, ten variables, namely scope of research, data quality, participant genuineness, duration of the interview, number of interviews, homogeneity, information strength, drilling ability, triangulation and research design, are used as inputs. A total of 20 different scenarios were created to demonstrate the applicability of the model proposed in the research and how the model works.

The authors reflected the results of each scenario in the table and showed the values for the sample size in qualitative studies in Table 4. The research results show that the proposed model's results are of a quality that will support the literature. The research findings show that it is possible to develop a model using the laws of fuzzy logic to determine the sample size in qualitative research.

The model developed in this research can contribute to the literature, and in any case, it can be argued that determining the sample volume is a much more effective and functional model than leaving it to the initiative of the researcher.

The purpose of this paper is to assess sub-national business cycle (BC) synchronization's impact on national cycles in four emerging markets economies with inflation targeting (IT-EMEs): Brazil, Colombia, South Korea and Mexico.

The authors use panel data models with fixed-effects and distributed lags.

The authors disclosed that sub-national synchronization increased national cycle amplitudes during expansion and recession phases. The authors also noticed that South Korea exhibited a more pronounced effect compared to Latin American countries, and this seemed to be associated with differences in the homogeneity of the production structures in the regions of these countries.

The authors cautioned that contrasting the findings with prior research on the effects of regional BC synchronization in IT-EMEs or with studies in different geographical contexts, is not possible due to the absence of prior research endeavors with this specific focus.

This study constitutes a first attempt to explain the impact of subnational cycle synchronization on the magnitude of national cycles in four IT-EMEs.

In pursuit of good governance and better allocation of resources, corruption and informal economy are of interest to policymakers and citizens alike. The impacts of military spending on the informal economy are scant. Moreover, the effects of an external factor, such as corruption that moderates this relationship, have largely been neglected in previous studies. Hence, this paper investigates how corruption moderates the effects of military spending on the informal economy in 30 Asian countries from 1995 to 2017.

This paper utilizes the GMM estimation technique, which allows cross-sectional dependence and slope homogeneity in panel data analysis, to examine the moderating role of corruption on the relationship between military spending and the informal economy.

Empirical findings from this paper indicate that an increase in military spending declines the informal economy while corruption increases it. Interestingly, the negative effects of military spending on the informal economy will mitigate with a greater degree of corruption in the Asian region. We also find that enhancing economic growth and attracting more FDI has reduced the informal economy in Asian countries.

To the best of the authors' knowledge, this is the first empirical study conducted to examine the moderating role of corruption on the military spending – informal economy nexus. Thus far, this approach has not been investigated in the existing literature, particularly for Asian countries.

Governments globally are adopting e-Government services to streamline administrative processes and meet citizens' expectations. This study investigates e-Government service quality from citizens' perspectives in 50 Greek municipalities, using the technology acceptance model (TAM) and cognitive theory.

The data from 707 respondents across 50 Greek municipalities are analyzed using structural equation modeling (SEM), ANOVA and moderation analysis. The study assesses the relationships between key factors and citizens' intentions to use e-Government services, examining the impact of demographics and the digital divide.

The study reveals that perceived attractiveness (PA), perceived usefulness (PU), perceived ease of use (PEOU) and awareness (AWA) significantly influence citizens' behavioral intentions (BINTs) toward municipal e-Government services. Interestingly, PEOU negatively impacts users' intentions, suggesting dissatisfaction with portal attractiveness and utility. The study explores the influence of demographic variables and the digital divide on citizens' BINTs, highlighting economic activity and income as crucial determinants.

The study emphasizes the significance of user-friendly design, PU, PEOU and AWA campaigns for the development of effective e-Government platforms. Strategies to address the digital divide and promote citizen engagement are essential for enhancing user experience, service utility and AWA, ultimately fostering a positive attitude toward e-Government.

Addressing demographic differences ensures inclusive e-Government systems, while bridging the digital divide promotes equitable service delivery and citizen engagement.

This research provides insights into factors influencing citizens' BINTs toward e-Government services. The study's examination of demographic attributes and the digital divide enhances understanding, contributing to the development of citizen-centric e-Government services and supporting inclusive digital transformations.

The concept of productivity is central to performance management and decision-making, although it is complex and multifaceted. This paper aims to describe a methodology based on the use of Big Data in a cluster analysis combined with a data envelopment analysis (DEA) that provides accurate and reliable productivity measures in a large network of retailers.

The methodology is described using a case study of a leading kitchen furniture producer. More specifically, Big Data is used in a two-step analysis prior to the DEA to automatically cluster a large number of retailers into groups that are homogeneous in terms of structural and environmental factors and assess a within-the-group level of productivity of the retailers.

The proposed methodology helps reduce the heterogeneity among the units analysed, which is a major concern in DEA applications. The data-driven factorial and clustering technique allows for maximum within-group homogeneity and between-group heterogeneity by reducing subjective bias and dimensionality, which is embedded with the use of Big Data.

The use of Big Data in clustering applied to productivity analysis can provide managers with data-driven information about the structural and socio-economic characteristics of retailers' catchment areas, which is important in establishing potential productivity performance and optimizing resource allocation. The improved productivity indexes enable the setting of targets that are coherent with retailers' potential, which increases motivation and commitment.

This article proposes an innovative technique to enhance the accuracy of productivity measures through the use of Big Data clustering and DEA. To the best of the authors’ knowledge, no attempts have been made to benefit from the use of Big Data in the literature on retail store productivity.

The studies that explore the impacts of national intellectual capital on informal economy are scant. Moreover, the effect of an external factor such as institutional quality that moderates this relationship has largely been neglected in previous studies. Institutions are considered important pillars to accumulate national intellectual capital and reduce shadow economy. As such, this paper aims to investigate how institutional quality moderates the effects of national intellectual capital on informal economy in 17 Asian countries from 2000 to 2018.

This paper uses the generalized method of moments techniques, which allow cross-sectional dependence and slope homogeneity in panel data, to examine the moderating role of institutional quality on the relationship between national intellectual capital and informal economy. Various tests are conducted to ensure the robustness of the findings.

Empirical findings from this paper indicate that an increase in national intellectual capital and institutional quality declines the informal economy. Interestingly, better institutional quality aggravates the negative effects of national intellectual capital on reducing the size of informal economy. The author also finds that enhancing international trade and economic growth results in a decrease in the informal economy in Asian countries.

Empirical findings offer policymakers an indication of the relationships between national intellectual capital, institutional quality and informal economy, pointing out that national intellectual capital and institutional quality should be strengthened to allow Asian countries to limit the informal economy.

This study provides a conceptual model through which the moderating role of institutional quality on the national intellectual capital–informal economy nexus can be recognized. This approach has thus far not been investigated in the existing literature. To the best of the author’s knowledge, this study makes an original contribution to the empirical of national intellectual capital and informal economy nexus and produces new insights into the fields of the moderating effects of institutional quality on this nexus.

The purpose of this paper is to present current state of understanding on jet electrodeposition manufacturing; to compare various experimental parameters and their implication on as deposited features; and to understand the characteristics of jet electrodeposition deposition defects and its preventive procedures through available research articles.

A systematic review has been done based on available research articles focused on jet electrodeposition and its characteristics. The review begins with a brief introduction to micro-electrodeposition and high-speed selective jet electrodeposition (HSSJED). The research and developments on how jet electrochemical manufacturing are clustered with conventional micro-electrodeposition and their developments. Furthermore, this study converges on comparative analysis on HSSJED and recent research trends in high-speed jet electrodeposition of metals, their alloys and composites and presents potential perspectives for the future research direction in the final section.

Edge defect, optimum nozzle height and controlled deposition remain major challenges in electrochemical manufacturing. On-situ deposition can be used as initial structural material for micro and nanoelectronic devices. Integration of ultrasonic, laser and acoustic source to jet electrochemical manufacturing are current trends that are promising enhanced homogeneity, controlled density and porosity with high precision manufacturing.

This paper discusses the key issue associated to high-speed jet electrodeposition process. Emphasis has been given to various electrochemical parameters and their effect on deposition. Pros and cons of variations in electrochemical parameters have been studied by comparing the available reports on experimental investigations. Defects and their preventive measures have also been discussed. This review presented a summary of past achievements and recent advancements in the field of jet electrochemical manufacturing.

The qualitative approach was applied the discover the optimum answers to the research objectives, which are (1) to understand the cultural and hedonistic characteristics of the (Lanna) Songkran festival; and (2) to examine the dilemma between cultural rituals and hedonistic activity for tourism.

This study used a case study of the Songkran festival in Chiang Mai to examine the dilemma between cultural rituals and hedonism for tourism, which brings lost or misperceived cultural values and identities. The semi-structured interview (SSI) with senior locals and participant observation during the festival was conducted in Chiang Mai, Thailand, to obtain the in-depth phenomena of the existing celebration pattern at the festival.

The study findings show three crucial phenomena that explain characteristics of unsynchronized cultural rituals and hedonistic activities for tourism: (1) the parallel phenomenon between cultural values and celebration practice, (2) the movement of local culture and(3) the hedonistic characteristics of the festival.

The study extends the knowledge on the interplay phenomena between cultural festivals and tourism; also, the involved stakeholders, such as local communities, public sectors and private sectors, can use the study findings in creating policies for using cultural festivals to promote a destination and urban economic development that will minimise cultural values distort while increase tourism economic values.

This study was conducted qualitatively, including SSIs and participant observation at the Songkran festival in Chiang Mai. The study findings were analysed, based on the empirical data, into significant themes representing the characteristics of dilemma phenomena within the festival.
