Probabilistic estimation of spinning reserves in smart grids with Bayesian-driven reserve allocation adjustment algorithm
Authors: Bapin Yerzhigit , Zarikas Vasilios 
Published: January 2021

Purpose
This study aims to introduce a methodology for optimal allocation of spinning reserves taking into account load, wind and solar generation by application of the univariate and bivariate parametric models, conventional intra and inter-zonal spinning reserve capacity as well as demand response through utilization of capacity outage probability tables and the equivalent assisting unit approach.

Design/methodology/approach
The method uses a novel approach to model wind power generation using the bivariate Farlie–Gumbel–Morgenstern probability density function (PDF). The study also uses the Bayesian network (BN) algorithm to perform the adjustment of spinning reserve allocation, based on the actual unit commitment of the previous hours.

Findings
The results show that the utilization of bivariate wind prediction model along with reserve allocation adjustment algorithm improve reliability of the power grid by 2.66% and reduce the total system operating costs by 1.12%.

Originality/value
The method uses a novel approach to model wind power generation using the bivariate Farlie–Gumbel–Morgenstern PDF. The study also uses the BN algorithm to perform the adjustment of spinning reserve allocation, based on the actual unit commitment of the previous hours.
Close enough: housing price effects of urban parks, reserves and volcanic parks in Auckland, New Zealand
Authors: Cheung Lydia , Fernandez Mario Andres 
Published: January 2021

Purpose
This study aims to test whether the size of and distance to the nearest green space has any effects on residential property transaction prices in Auckland, New Zealand.

Design/methodology/approach
This paper divides all green spaces in Auckland into three categories, namely, urban parks, regional reserves and volcanic parks (a unique feature in Auckland, New Zealand). This study uses six years of residential property transaction data to estimate hedonic price regressions. For each property, this paper calculates the size of and distance to the nearest park in each category.

Findings
The logged sizes of the nearest regional reserve and volcanic park have positive effects on property prices. The logged distances to the nearest urban park and volcanic park are insignificant, while the logged distance to the nearest regional reserve is positively significant. In other words, homebuyers prefer larger regional reserves and volcanic parks and prefer to be further away.

Originality/value
Auckland is ranked as a top-five city in the world in terms of the proportion of public green space, trailing four European cities. However, because of Auckland’s much younger age, it presents a very different urban form. The study shows that the distribution of green space (not only its total amount) can bring negative capitalization on property prices.

Authors: Yu Lie , Ding Lei , Yu Fangli , Zheng Jianbin , Tian Yukang 
Published: January 2021

PurposeThe purpose of this paper is to apply a intelligent algorithm to conduct the force tracking control for electrohydraulic servo system (EHSS). Specifically, the adaptive neuro-fuzzy inference system (ANFIS) is selected to improve the control performance for EHSS.Design/methodology/approachTwo types of input–output data were chosen to train the ANFIS models. The inputs are the desired and actual forces, and the output is the current. The first type is to set a sinusoidal signal for the current to produce the actual driving force, and the desired force is chosen as same as the actual force. The other type is to give a sinusoidal signal for the desired force. Under the action of the PI controller, the actual force tracks the desired force, and the current is the output of the PI controller.FindingsThe models built based on the two types of data are separately named as the ANFIS I controller and the ANFIS II controller. The results reveal that the ANFIS I controller possesses the best performance in terms of overshoot, rise time and mean absolute error and show adaptivity to different tracking conditions, including sinusoidal signal tracking and sudden change signal tracking.Originality/valueThis paper is the first time to apply the ANFIS to optimize the force tracking control for EHSS.

Authors: Kunhibava Sherin , Mustapha Zakariya , Muneeza Aishath , Sa'ad Auwal Adam , Karim Mohammad Ershadul 
Published: January 2021

Purpose
This paper aims to explore issues arising from ṣukūk (Islamic bonds) on blockchain, including Sharīʾah (Islamic law) and legal matters.

Design/methodology/approach
A qualitative methodology is used in conducting this research where relevant literature on ṣukūk was reviewed. Through a doctrinal approach, the paper presents analyses on the practice of ṣukūk and ṣukūk on blockchain by discussing its legal, Sharīʾah and regulatory issues. This culminates in a conceptual analysis of blockchain ṣukūk and its peculiar challenges.

Findings
This paper reveals that digitizing ṣukūk issuance through blockchain remedies certain inefficiencies associated with ṣukūk transactions. Indeed, structuring ṣukūk on a blockchain platform can increase transparency of underlying ṣukūk assets and cash flows in addition to reducing costs and the number of intermediaries in ṣukūk transactions. The paper likewise brings to light legal, regulatory, Sharīʾah and cyber risks associated with ṣukūk on blockchain that confront investors, practitioners and regulators. This calls for deeper collaboration in research among Sharīʾah scholars, lawyers, regulators and information technology experts.

Research limitations/implications
As a pioneering subject, the paper notes the prospects of blockchain ṣukūk and the current dearth of literature on it. The paper would assist relevant Islamic capital market entities and authorities to determine the potential and impact of blockchain ṣukūk in their respective businesses and the financial system.

Practical implications
Blockchain ṣukūk will assist in addressing issues inherent in classical ṣukūk and in paving the way to innovative solutions that will facilitate and enhance the quality of ṣukūk transactions. For that, ṣukūk would require appropriate regulatory technology to address its governance and regulation peculiarities.

Originality/value
Integrating ṣukūk with blockchain technology will add value to it. The paper advances the idea that blockchain ṣukūk revolutionises ṣukūk and enhances its practice against known inadequacies.

Moral foundations and financial performance: the effect of moral cues during times of earnings uncertainty
Authors: Jancenelle Vivien E. 
Published: January 2021

PurposeThis paper aims to investigate whether cues of morality can mitigate stock sell-offs in the face of earnings uncertainty prior to earnings conference calls and draws on moral foundations theory to study the effect of universal moral cues (harm/care and fairness/reciprocity rhetoric) and primarily conservative moral cues (ingroup/loyalty, authority/respect and purity/sanctity rhetoric) on market performance.Design/methodology/approachThe study relies on a longitudinal data set of 1,920 firm-quarter observations corresponding to calls held by firms listed on the S&P 500 in 2015 and relies on computer-assisted-text-analysis and event-study methodology to test hypotheses.FindingsThe results suggest that cues of universal moral foundations have a mitigating effect on stock sell-offs and are able to create firm value; while cues primarily conservative moral foundations are not found to have an effect on market performance.Originality/valueThis investigation highlights why earnings conference calls may serve as a valuable tool for communicating a firm’s moral inclination and why universal morality may appeal to a wider range of shareholders than primarily conservative morality.

Authors: Shokri Alireza , Antony Jiju , Garza-Reyes Jose Arturo , Upton Michelle 
Published: January 2021

PurposeThis work presents a synthesis of current literature published from 2010 to provide an overall understanding of the sustainable implementation of Lean Six Sigma (LSS) projects in terms of project approaches rather than outcomes.Design/methodology/approachA comprehensive and validated ten-step model was applied to conduct a scoping review with the following three broad phases: “review planning”, “review execution” and “review reporting”.FindingsThe analysis shows that while a few geographically and methodologically broad research studies have been conducted on LSS and green manufacturing integration, no studies have examined organisational culture or conducted readiness assessments on the sustainable implementation of LSS projects in the manufacturing sector.Research limitations/implicationsThe present study contributes to existing knowledge by describing the current state of research on green LSS integration. The study also identifies a lack of research on the deployment of sustainable LSS projects for manufacturers. Further empirical analyses that include case studies must be conducted to assess the negative environmental impacts of LSS projects.Originality/valueThis study serves as an initial call for practitioners and research scholars to favour the sustainable deployment of LSS projects in manufacturing alongside the use of traditional approaches with a focus on costs, quality and delivery.

Authors: Akter Shabiha , Uddin Md Hamid , Tajuddin Ahmad Hakimi 
Published: January 2021

PurposePerformance assessment of microfinance institutions (MFIs) has long been a question of considerable research interest. The dual goals – financial performance and social performance of MFIs widely studied yet remain unsolved in the existing literature. To assess the knowledge structure of research in this area and to aid future research, we review the literature with bibliometric analysis.Design/methodology/approachOur study has used bibliographic data of 1,252 scientific documents indexed in the Scopus database from 1995 to 2020 (June 05). We have used the “bibliometrix” package in R language to analyze the data and illustrate the findings.FindingsWe find that there has been an increasing trend in publications, especially from 2006 onwards. Various bibliometric indicators allow us to follow the progression of knowledge along with identifying the most contributing and impactful authors, publication sources, institutions and countries. We illustrate the major research themes and identify that “poverty alleviations”, “group lending” and “credit scoring” are the major emerging and specialized themes besides the basic research evolved around “microfinance” or “microcredit”. Our further analysis of thematic evolution over different time frames reveals that “financial performance” aspect is getting more attention in recent times in evaluating the performance of MFIs.Originality/valueThe insights of knowledge accumulated from our bibliometric review and thematic analysis provide researchers with an efficient comprehension of the advancement of the research on microfinance performance and offer avenues for future scientific endeavors.
A risk-reduction framework for urban cultural heritage: a comparative study on Italian historic centres
Authors: Giuliani Francesca , De Paoli Rosa Grazia , Di Miceli Enrica 
Published: January 2021

PurposeThe purpose of this paper is to present and validate a large-scale methodology for risk assessment and management in cultural heritage sites, taking into account their specific tangible or intangible values. Emphasis is given to historic centres that are key resources in building resilience to disasters but are also highly vulnerable due to several factors, such as the characteristics of the built environment, the community and social life, the lack of risk awareness and maintenance and finally the poor regulatory framework for their management and valorisation.Design/methodology/approachThe multi-step procedure starts from the assessment of the attributes of cultural heritage in order to identify priorities and address the analysis. Then, it evaluates the primary and secondary hazards in the area, the vulnerabilities and threats of the site and the impacts of the chain of events. Finally, it allows for calibrating a site-specific set of mitigation, preparedness, response and recovery measures.FindingsThe application to two case studies in the Italian peninsula, the historic centres of San Gimignano and Reggio Calabria, allows for identifying research gaps and practical opportunities towards the adoption of common guidelines for the selection of safety measures.Originality/valueBy providing a qualitative assessment of risks, the research points out the potentialities of the methodology in the disaster risk management of cultural heritage due to its capacity to be comprehensive and inclusive towards disciplines and professionals.
When is more really more? The effect of brands on choice overload in adolescents
Authors: Misuraca Raffaella , Ceresia Francesco , Nixon Ashley E. , Scaffidi Abbate Costanza 
Published: January 2021

PurposeResearch on choice overload with adult participants has shown that the presence of a brand significantly mitigates the phenomenon. The purpose of this study is to investigate whether these findings can be expanded to a population of adolescents, where it has already been shown that choice overload occurs in a similar way as adults.Design/methodology/approachStudies 1 and 2 aim to test whether the presence of a brand name mitigates the adverse consequences of choice overload in adolescents. In line with prior research on choice overload, in both studies, the authors compared between-subjects differences in the levels of reported dissatisfaction, difficulty and regret in a choice condition where adolescents chose among either 6 or 24 options associated with brand names and in another choice condition where adolescents chose among the same 6 or 24 options but not associated with brand names.FindingsThis paper presents evidence from two studies that when facing either a large or a small amount of choice options that are associated with brand names, choice overload disappears among adolescents. Conversely, when no brands are associated to the choice options, adolescents report choice overload, that is a greater dissatisfaction, difficulties and regret with larger (versus smaller) assortments.Practical implicationsPrior research on choice overload has led to recommendations that marketers and other choice architects should simply reduce choice options or assortments to improve consumers’ satisfaction. However, our finding suggests that this recommendation may be invalidated when brands are present, at least for certain age groups. Adolescents cope indeed very well with large assortments of branded products.Originality/valueThe research adds to the existing understanding of choice overload, demonstrating that the brand is a moderator of the phenomenon for adolescents, who currently represent a large portion of the market. A second important contribution of this work is that it extends prior research on choice overload to real-world consumer scenarios, where consumers choose among products with a brand, rather than among products described only by technical characteristics or nutritional values, as in classical studies on choice overload.
Plate-fin heat exchanger network modeling, design and optimization – a novel and comprehensive algorithm
Authors: Ramezanpour Jirandeh Reza , Ghazi Mehrangiz , Sotoodeh Amir Farhang , Nikian Mohammad 
Published: January 2021

Purpose
The purpose of this paper is to present a novel and applied method for optimum designing of plate-finned heat exchanger network. Considering the total annual cost as the objective function, a network of plate-finned heat exchanger is designed and optimized.

Design/methodology/approach
Accurate evaluation of plate-finned heat exchanger networks depends on different fin types with 10 different geometrical parameters of heat exchangers. In this study, fin numbers are considered as the main decision variables and geometrical parameters of fins are considered as the secondary decision variables. The algorithm applies heat transfer and pressure drop coefficients correction method and differential evolution (DE) algorithm to obtain the optimum results. In this paper, optimization and minimization of the total annual cost of heat exchanger network is considered as the objective function.

Findings
In this study, a novel and applied method for optimum designing of plate-finned heat exchanger network is presented. The comprehensive algorithm is applied into a case study and the results are obtained for both counter-flow and cross-flow plate-finned heat exchangers. The total annual cost and total area of the network with counter-flow heat exchangers were 12.5% and 23.27%, respectively, smaller than the corresponding values of the network with cross-flow heat exchanger.

Originality/value
In this paper, a reliable method is used to design, optimize parameters and the economic optimization of heat exchanger network. Taking into account the importance of plate-finned heat exchangers in industrial applications and the complexity in their geometry, the DE methodology is adopted to obtain an optimal geometric configuration. The total annual cost is chosen as the objective function. Applying this technique to a case study illustrates its capability to accurate design plate-finned heat exchangers to improve the objective function of the heat exchanger network from the economic viewpoint with the design of details.
Macroeconomic uncertainty and the spatiotemporal evolution of innovation networks: evidence from China's urban technology supply chain
Authors: Jin Peizhen , Wu Hongyi , Yin Desheng , Zhang Yupeng 
Published: January 2021

PurposeBased on the perspective of technology supply chain, this study explores the effect of macroeconomic uncertainty regarding the spatiotemporal evolution of urban innovation networks to establish causality.Design/methodology/approachIt collects patent trading data for 283 cities in China (2005–2017) and employs the spatial econometric model to investigate the causal relationship.FindingsThe regional transfer of advanced technology in China is rising sharply, and the innovation network based on patent trading is typically high-density, multi-direction and wide-spreading. Further, macroeconomic uncertainty has a negative effect on the scale of innovation flows and the absorptive capacity in eastern cities. However, it has no significant impact on the innovation network characteristics in developed cities. In contrast, macroeconomic uncertainty is detrimental for the absorptive capacity and node importance in inland and undeveloped cities.Practical implicationsAs macroeconomic uncertainty increases, it is important to improve the quality of the urban innovation network with a better understanding of heterogeneity to promote further suitability innovation at the region-level.Originality/valueThis study highlights a clear and distinctive view that macroeconomic uncertainty not only directly affects the evolution of the urban innovation network but also indirectly affects the characteristics of other city nodes via the spatial spillover mechanism.
