Effect of presidential elections on investor herding behaviour in African stock markets
Authors: Musah Godwin , Domeher Daniel , Alagidede Imhotep 
Published: August 2022

PurposeThe purpose of this paper is to investigate investor herding behaviour and the effect of presidential elections on investor herding behaviour in African stock markets at the sector level.Design/methodology/approachThe study segregates listed firms into financial, consumer goods, consumer services and basic materials sectors and uses the cross-sectional absolute deviation approach as a metric of detecting herding in each of the sectors. The authors extend the model to tease out the effect of presidential elections on investor herding behaviour.FindingsThe study reveals that sectoral differences are fundamental to the evolution of herding. Herding is prominent in a financial services sector dominated by banks. The phenomenon also prevails in markets with smaller consumer goods and services sectors. A post-presidential election effect on investor herding is found for the consumer goods and services sectors of Ghana and a pre-presidential election effect is documented in Nigeria's consumer services sector. The authors conclude that post-presidential election effect is as a result of political connections whilst a pre-presidential election effect is attributable to political business cycles.Research limitations/implicationsThe study is based on four African countries due to data constraints. Nonetheless, the study is the first in Africa to the best of the authors' knowledge, and the results are very solid and have a lot of practical and policy implications.Practical implicationsThe study has implications for investors as it guides investment behaviour in pre- and post-presidential election periods.Originality/valuePast studies on investor herding behaviour in African stock markets have largely concentrated on the aggregate market. Knowledge on sectoral differences in investor herding is almost non-existent for African stock markets. Furthermore, premised on the fact that stock markets react to presidential elections, there is no known study that have attempted to examine the effect of presidential elections on investor herding behaviour. This paper contributes to the literature by providing evidence on sectoral differences in investor herding behaviour and the effect of presidential elections on sectoral herding behaviour.

Dynamics of national development and regional disparity: evidence from 184 countries
Authors: Jadhav Vivek 
Published: August 2022

PurposeThe existence of the regional Kuznets curve, i.e. an inverted U-shaped relationship between regional disparity and economic development is widely debated and discussed. The bell-shaped curve of the spatial growth process where during the initial phase inequality increases and then reduces is theoretically supported by Myrdal (1957), Hirschman (1958), and Williamson (1965). It becomes important to understand regional Kuznets curve globally. Understanding the relationship between regional disparity and economic development becomes essential for public policy for balanced regional growth.Design/methodology/approachRegional Kuznets Curve which is an inverted U-shaped relationship between regional disparity and economic development is not a new phenomenon. Theoretical framework by Myrdal (1957), Hirschman (1958), and Williamson (1965) support the an inverted U-shaped relationship. To understand the relationship between regional disparity and economic development, the authors investigate the regional Kuznets curve by using data for 184 countries and 1765 subnational regions. Using parametric, semi-parametric, and non-parametric, it is found that there exists an inverted U-shaped relationship between regional disparity and economic development. The presence of the regional Kuznets curve is observed. As the theoretical framework suggests, regional inequality increases with income initially and decreases after attaining a certain level of income. This study identifies two stages of divergence-convergence where in the first stage, divergence across regions in a country happens with increasing income and in the later stage, convergence across regions in a country occurs with increasing income.FindingsUsing the parametric approach (panel data analysis), semi-parametric and non-parametric approaches, it is found that there exists a regional Kuznets curve. It is found that there exists an inverted-U relationship between regional inequality and per capita GNI. This suggests that the divergence-convergence passes through two stages. In the first stage, divergence across regions in a country happens with increasing income while in the later stage convergence occurs.Originality/valueThis research work has done three important things which fill the research gap that exists in the literature: (1) constructing the Gini coefficient to measure the regional inequality for 184 countries using 1765 subnational regional data; (2) using a parametric approach (panel data analysis) to understand the regional Kuznets phenomenon and (3) using a semi-parametric approach and non-parametric approach to understand the regional Kuznets phenomenon.
Access and tinkering: designing assistive technologies as political practice–A discussion with Zeynep Karagöz, Thomas Miebach and Daniel Wessolek
Authors: Bieling Tom , Şahinol Melike , Stock Robert , Wiechern Anna–Lena 
Published: August 2022

PurposeThis contribution shows perspectives of experts from different disciplines and professional backgrounds in order to elaborate on maker approaches such as do-it-yourself prosthetics and collaborative tools. As a result, aspects of open source practices related to medical and assistive technologies will be critically reflected upon. In addition, implications of heterogeneous interests, economic implications and everyday achievements of social material assemblages produced through participatory design research are discussed.Design/methodology/approachIn order to address an interdisciplinary and transdisciplinary perspective on the relationships between body (differences) and technology, it is necessary to bring together studies from both Science and Technology Studies (STS) and crip technoscience as well as approaches from participatory design research and practice. This challenge was addressed by a roundtable organized as part of the third network meeting of the Dis/Ability and Digital Media Research Network on 16 September 2020.FindingsAgainst the backdrop of “crip technoscience” DIY and collaborative open source practices are not only understood as valuable alternatives to standardized medical prosthetics and assistive devices. These bottom-up approaches which draw from the expert knowledge of disabled users (Hamraie and Fritsch, 2019) also facilitate devices that defy categories such as “prosthetic” or “medical aid” not only aesthetically but semantically, too.Originality/valueThe Network Dis/Abilities and Digital Media intends to integrate media and technology studies with disability studies on a theoretical level. This round table discussion delivers proof of how – on the practical level – technology and dis/ability need to be thought of as relational and co-constitutive (Mills and Sterne, 2017).
The effect of cultural orientations (performance and sociality) on country innovation: a trajectories analysis perspective
Authors: Ramirrez-Urraya Agustin , Escandon-Barbosa Diana , Salas Jairo 
Published: August 2022

Purpose
This study aims to analyze the effects of cultural orientations (performance and sociality) on the trajectories of innovation inputs and their results in different countries worldwide between 2011 and 2021.

Design/methodology/approach
As a technique for data analysis, one of the spatial Bayesian models and Gray forecasting methods is used. This technique is adequate to achieve the objectives of the investigation because it allows analyzing how the variables move in time ranges and allow the generation of forecasts. This model also allows knowing if there are spills, which investing in a country can positively affect countries with geographical proximity. The databases used were the Global Innovation Index with data from 131 nations and the Globe Project with data from 157 countries between 2011 and 2021. The variables analyzed are institutions, human capital, research infrastructure, market sophistication and business sophistication. On the other hand, regarding moderations of cultural orientations, The Globe Project developed two factors: performance orientation (high degree of masculinity, avoidance of ambiguity, power distance and future orientation) and humane orientation (high-level of femininity, institutional and societal collectivism).

Findings
The results reveal that all inputs grow at different rates over time. In the case of institutions, it is the most difficult to generate changes over time. However, human capital, market sophistication and business sophistication are the ones that have grown the most over time, regardless of the country’s cultural orientation.

Research limitations/implications
Among the main limitations is the set of data used because it only considers one approach to culture, especially the one considered by Hofstede. However, other approaches could help evaluate the results of this research. Considering the results obtained, the study attempts to provide a different view of the effects of cultural variables on companies’ innovation performance in different countries in the world. In the same way, evaluating these effects allows firms to consider variables associated with the country that will affect the strategies and performance of the firm.

Practical implications
The results achieved make it possible to strengthen the analysis of the countries’ strategies when it comes to innovation, especially in the permanent evaluation of the results that allow to encourage changes in the execution of innovative activities to maintain their performance over time.

Social implications
The contributions allow us to understand the dynamics of innovation in the knowledge and creative outputs of countries over time.

Originality/value
The trajectory analysis used in the data analysis is perhaps one of the most robust techniques that makes a time series analysis. This allows identifying trajectories for the independent variables of the study and their influence on the innovation of the country.

Published: August 2022

PurposeThis paper aims to find the impact of blockchain supply chain on supply chain performance with a mediating role of supplier trust, traceability and transparency.Design/methodology/approachData was collected using the purposive sampling technique on a five-point Likert scale from 150 respondents. For data analysis, IBM SPSS and Smart PLS 3.3.7 were used to test the hypotheses by evaluating the structural equation modeling.FindingsThe blockchain supply chain found a significant effect on supply chain performance. Moreover, there is a substantial effect of the blockchain supply chain on supply chain performance via mediators, including supplier trust, supply chain traceability and supply chain transparency. Further, the mediation type of all mediators was full mediation in the relationships between blockchain supply chain and supply chain performance.Research limitations/implicationsThe research findings are helpful for industrialists, supply chain practitioners and policymakers. The practitioners can adopt blockchain technology to enhance inter-organizational collaboration, develop trust, data visibility and traceability, and critical decisions, ultimately bringing sustainable growth for the firm.Originality/valueThe outcomes of this research enrich the literature and share the impact of one of the most trending technologies in the supply chain perspective. Future research can empirically test the relationship between blockchain and supply chain sustainability.
Adapting to dynamic business environments: a comparative study of family and non-family firms operating in Western Australia
Authors: Duarte Alonso Abel , Vu Oanh Thi Kim , Kok Seng Kiat , O'Shea Michelle 
Published: August 2022

Purpose
The purpose of this study is to examine adaptation to a dynamic business environment from the perspective of family and non-family firms. Furthermore, the study provides a comparative component and proposes a theoretical framework to understand firm adaptation, incorporating the dynamic capabilities approach.

Design/methodology/approach
Semi-structured, in-depth, face-to-face interviews were undertaken predominantly with firm owners and managers of family and non-family-owned firms operating in Western Australia.

Findings
Regardless of firms’ family or non-family background, valuable, rare, imperfectly imitable and non-substitutable attributes were strongly associated with both groups. Moreover, expertise, tacit and new knowledge, innovation or established brand image emerged as key adaptive responses to challenges posed by new trends, consumer expectations, increased demand or competition. These attributes allowed firms to sense and seize opportunities, and experience transformational processes to remain competitive. Implications of the findings and future research directions will be discussed.

Originality/value
First, and empirically, the study’s objectives contribute to addressing extant research gaps, including scant research on methodologies and innovative approaches used by family firms to adapt to contemporary challenges. Thus, the study complements entrepreneurship scholarly discourses on firms’ adaptation. Second, the chosen inductive approach results in the development of a framework, which also exhibits various relationships with the adopted dynamic capabilities approach. Both the findings and the developed framework enhance the understanding of adaptive behaviour among both family and non-family firms. Finally, the study contributes to the literature examining firms operating in geographically dispersed and isolated regions.
A graph-based path planning method for additive manufacturing of continuous fiber-reinforced planar thin-walled cellular structures
Authors: Zhang Guoquan , Wang Yaohui , He Jian , Xiong Yi 
Published: August 2022

Purpose
Composite cellular structures have wide application in advanced engineering fields due to their high specific stiffness and strength. As an emerging technology, continuous fiber-reinforced polymer additive manufacturing provides a cost-effective solution for fabricating composite cellular structures with complex designs. However, the corresponding path planning methods are case-specific and have not considered any manufacturing constraints. This study aims to develop a generally applicable path planning method to fill the above research gap.

Design/methodology/approach
This study proposes a path planning method based on the graph theory, yielding an infill toolpath with a minimum fiber cutting frequency, printing time and total turning angle. More specifically, the cellular structure design is converted to a graph first. Then, the graph is modified to search an Eulerian path by adding an optimal set of extra edges determined through the integer linear programming method. Finally, the toolpath with minimum total turning angle is obtained with a constrained Euler path search algorithm.

Findings
The effectiveness of the proposed method is validated through the fabrication of both periodic and nonperiodic composite cellular structures, i.e. triangular unit cell-based, Voronoi diagram-based and topology optimized structures. The proposed method provides the basis for manufacturing planar thin-walled cellular structures of continuous fiber-reinforced polymer (CFRP). Moreover, the proposed method shows a notable improvement compared with the existing method. The fiber cutting frequency, printing time and total turning angle have been reduced up to 88.7%, 52.6% and 65.5%, respectively.

Originality/value
A generally applicable path planning method is developed to generate continuous toolpaths for fabricating cellular structures in CFRP-additive manufacturing, which is an emerging technology. More importantly, manufacturing constraints such as fiber cutting frequency, printing time and total turning angle of fibers are considered within the process planning for the first time.

Authors: Anyatonwu Sophia C. , Callaghan Timothy 
Published: August 2022

AbstractObjectiveThe object of this study is to explore the impact of discretionary income on the overall well‐being of Americans.Data SourceThe data source used for this study was 2017 Behavioral Risk Factor Surveillance System data comprising 12 states that used the Social Determinants of Health (SDOH) module.Study DesignMultivariable logistic regression models were used to analyze the relationship between discretionary income and self‐reported health status after adjusting for common SDOH measures, sociodemographic factors, chronic conditions, and perspectives and experiences of respondents regarding specific aspects of their health. Average marginal effects (AME) were reported.Data Collection/Extraction MethodsNot applicable.Principal FindingsAt all income levels, those with discretionary income at the end of the month were 6–7 percentage points more likely to report better than average health than those with none, controlling for other factors (AME: 0.07, 95% CI: 0.02–0.12).ConclusionOur study suggests that discretionary income has a role to play in overall health and well‐being that goes beyond that of disposable income and may be an important resource for diverse communities.

Published: August 2022

AbstractBackgroundThe serotonin transporter (SERT) mRNA was previously reported to be a quantitative and pathophysiology‐based biomarker of heavy drinking in 5HTTLPR:LL genotype‐carriers treated with ondansetron. Here, we validated the potential use of SERT mRNA for quantitative prediction of recent alcohol consumption (in the absence of treatment) and compared it with the known biomarkers ethyl glucuronide (EtG) and ethyl sulfate (EtS).MethodsBinge drinking men and women of European ancestry aged 21 to 65 years were enrolled in a 12‐day, in‐patient, randomized, double‐blind, crossover study, where they were administered three beverage doses (placebo, 0.5 g/kg [0.4 g/kg] ethanol, and 1 g/kg [0.9 g/kg] ethanol for men [women]) individually in three 4‐day periods (experiments), separated by minimum 7‐day washout period. Diet, sleep, and physical activity were controlled throughout the inpatient experiments. Twenty‐nine participants were randomized to receive beverage doses counterbalancing the sequence of treatment and gender within subgroups stratified by SERT genotypes 5HTTLPR:LL+rs25531:AA (LALA) versus 5HTTLPR:LS/SS. Peripheral venous blood was collected daily for (1) quantification of SERT mRNA (the primary outcome measure) using qRT‐PCR and (2) plasma EtG and EtS levels using tandem mass‐spectrometry.ResultsThe association between administered beverage dose and SERT mRNA from completers of at least one 4‐day experiment (N = 18) assessed by a linear mixed model was not statistically significant. Significant positive associations were found with beverage dose and plasma EtG, EtS and EtG/EtS ratio (β = 5.8, SE = 1.2, p < 0.0001; β = 1.3, SE = 0.6, p = 0.023; and β = 3.0, SE = 0.7, p < 0.0001, respectively; the C‐statistics for discriminating outcomes were 0.97, 0.8, and 0.92, respectively). Additionally, we observed a sequence effect with a greater placebo effect on SERT mRNA when it was administered during the first experiment (p = 0.0009), but not on EtG/EtS measures.ConclusionThe findings do not validate the use of SERT as a biomarker of heavy drinking. Larger and more innovative studies addressing the effects of placebo, race, gender, and response to treatment with serotonergic agents are needed to fully assess the utility of SERT as a biomarker of heavy and binge drinking.
