Published: January 2023

PurposeWorld imports of Italian sparkling wines fell by 9% in value and 5% in quantities. In view of this, the quality characterisation of these products is desirable to increase their market value and restore their global visibility.Design/methodology/approachFor this purpose, in this paper, heavy metals (Cd, Co, Cr, Cu, Fe, Ga, Hf, Hg, Mn, Mo, Nb, Ni, Pb, Re, Sb, Sn, Ta, Th, Tl, U, W, V, Zn, Zr), rare Earth elements (REEs) (Ce, Dy, Er, Eu, Gd, Ho, La, Lu, Nd, Pr, Sm, Tb, Tm, Yb) and isotopes ratio (208Pb/206Pb, 207Pb/206Pb, 206Pb/204Pb, 208Pb/207Pb, 87Sr/86Sr) were analysed in Italian sparkling wines with Protected Designation of Origin (PDO) certification by High Resolution Inductively Coupled Plasma Mass Spectrometry (HR-ICP-MS) and MultiCollector Inductively Coupled Plasma Mass Spectrometer (MC-ICP-MS). The samples were produced in the Veneto region, and they were compared to white and red wines from the same area.FindingsSparkling wines present a characteristic elemental pattern compared to white and red ones, with lower content of heavy metals and higher content in REEs. The ratio 87Sr/86Sr resulted in a powerful micro-scale geographical origins marker while Pb ratios as winemaking process one, both useful to prevent possible frauds. Multivariate data analyses, such as PCA and PLS-DA, were used to develop a model of recognition of Venetian sparkling wines.Originality/valueThe good classification of sparkling wines was achieved (95%), proving the suitable use of these analytes as markers for recognising sparkling wines and their geographical origin verification. To the best of the authors’ knowledge, this is the first study investigating heavy metals, REEs and isotopes in Venetian sparkling wine for their recognition.

In their explanation, they link their action with the root causes of vulnerability embedded in their socio-cultural traditions and collective identity.Research limitations/implicationsThis article makes a case for the importance of local culture and epistemologies in understanding disaster vulnerability and responsibility attribution.Originality/valueThis article is original in researching Vietnamese farmers' responsibility attribution, their aesthetic reflexivity, collective habitus and the socio-cultural root causes of disaster.
An integrated risk assessment method for cross-regional mega construction projects
Authors: Xiang Pengcheng , Xia Xin , Pang Xianya 
Published: January 2023

PurposeThe purpose of this paper is to develop a novel integrated risk assessment method from the system perspective to evaluate the risk of the cross-regional mega construction project (CMCP). Furthermore, this paper aims to confirm the core risk source factors and refine the risk management strategies of CMCPs through a case study.Design/methodology/approachBased on the analysis of the risk system of CMCPs, the concept model and risk assessment principles of integrated risk assessment were confirmed. The risk source factors and project objectives of the CMCP were identified from a literature review, export interview and case analysis. According to the vulnerability theory, the integrated risk assessment model was developed by involving vulnerabilities, threats, objectives and interaction of those factors synthetically. Then, ZW high-speed railway from China was analyzed to verify the feasibility and effectiveness of the proposed method.FindingsAs a result, 12 threat factors and 12 vulnerability factors were identified. Based on the case study, the main external threat comes from T13 (conflicts of interest between local governments) and T23 (harsh natural environment); the most easily exploited internal vulnerabilities were V11 (complexity of technology), V13 (lack of experience in technical application), V21 (inadequate experience) and V23 (lack of interest coordination mechanism). Moreover, the economic objective was most affected.Practical implicationsIt is essential to develop an interest coordination mechanism for CMCPs. The harsh natural environment is a critical factor, but it also promotes technological innovation and iteration. Public opinions in different regions are critical for CMCPs, and more emphasis should be placed on public opinion surveys of CMCPs. Moreover, diverse and flexible environmental protection strategies should apply in CMCPs.Originality/valueThis research has the following three contributions. First, based on vulnerability theory, an integrated risk assessment approach of CMCPs is developed, which enriches the risk measurement method system and provides inspiration for future research on risk in the construction industry. Second, the risk sources of CMCPs are identified from the perspective of vulnerability and threat to provide clear guidance for the risk management of CMCPs. Third, the core risk source factors and management strategies confirmed by the case study will be beneficial for various governments in different regions and project managers to optimize the project management scheme, as they are transferable management experiences.
The effect of construction sustainability system interactions on financial performance: a sociotechnical perspective
Authors: Orr Stuart , Jadhav Akshay 
Published: January 2023

PurposeConstruction sustainability (CS) is a strategic reaction to the sustainability expectations of the construction industry's external stakeholders. The extant literature has viewed the environmental, social and economic dimensions of CS as having independent effects on financial performance. Due to the influence of common stakeholders, however, interactions in these dimensions will be present in their effect on financial performance. Accordingly, this study identifies the mechanisms of the interactions between the three CS dimensions and how they jointly affect financial performance.Design/methodology/approachContent analysis of GRI reports of 60 large construction organisations, followed by a hierarchical regression analysis was used to identify the interactions between environmental, social and economic CS in their effect on financial performance.FindingsEconomic CS was found to indirectly, and not directly, affect financial performance, the effect being mediated by both environmental and social CS. Environmental CS was found to have a strong negative effect on financial performance, whilst social CS was found to have a strongly significant positive effect on financial performance.Practical implicationsThe motivation for engaging in CS is that investment in economic CS will have a positive effect on both environmental and social CS outcomes, which, in turn can have a combined effect on financial performance.Originality/valueThis is one of the first studies investigating the effect of interactions between the environmental, social and economic CS dimensions on the financial performance of construction organisations. It is also one of the first studies that applies a sociotechnical framework to this relationship.
Identifying computational thinking in students through project-based problem-solving activities
Authors: Yang Dazhi , Snelson Chareen , Feng Shi 
Published: January 2023

Purpose
This paper aims to identify computational thinking (CT) in 4th to 6th grade students in the context of project-based problem-solving while engaged in an after-school program.

Design/methodology/approach
This case study approach was selected due to its suitability for answering “how” or “why” questions about real-world phenomena within a set context (Creswell and Poth, 2018; Yin, 2018). This was an appropriate fit given the context of an after-school program and the research question asked how to identify learners’ demonstrated CT through project-based learning hands-on activities and problem-solving in a naturalistic environment.

Findings
Results show that heuristics, algorithms and conditional logic were observed more than other components of CT such as data collection, simulations and modeling. Descriptions of common activities in a naturalistic learning environment are presented to illustrate how the students practiced CT over time, which could help readers develop an understanding of CT in conjunction with hands-on problem-solving activities in elementary students. Identifying and classifying CT in this study focused on students’ learning process.

Originality/value
This study contributes to the challenging field of evaluating CT while focusing on observable behaviors and problem-solving activities with various degrees of teacher’s facilitation instead of final artifacts. Implications for researchers and educators interested in integrating CT in K-12 learning and its assessment are discussed.

Authors: Roque Júnior Luiz Carlos , Frederico Guilherme F. , Costa Maykon Luiz Nascimento 
Published: January 2023

PurposeA globalized world demands proactive tactics from organizational supply chains. Companies should be capable of mitigating the impacts of natural and manmade disasters, which requires that they understand their stages of maturity and resilience. This study develops a theoretical model of the relationship between maturity and resilience, seeking to guide decision-making about aligning these two concepts.Design/methodology/approachA systematic literature review was conducted to identify the constructs that form the basis for our proposed maturity and resilience model.FindingsThe authors identified the key constructs related to maturity and resilience by analyzing the existing literature and selected 13 constructs and 3 maturity stages to construct our maturity and resilience model.Research limitations/implicationsThis research contributes to the supply chain management literature, especially that involving the themes of maturity and resilience. It can encourage research to develop future empirical research in the field to validate and overcome the limitations of the initial model the authors propose.Practical implicationsThe authors’ proposed model supports supply chain managers in establishing strategies to increase resilience based on the maturity of the chains they manage, enabling them to face crises such as the coronavirus disease 2019 (COVID-19) pandemic.Originality/valueThe model presents a holistic view of maturity and resilience in supply chains contributing to supply chain theory by examining the alignment between the two themes.

Published: January 2023

PurposeThe main purpose of the study was mechanical designing, simulation and manufacturing process for a new model of octocopter V-frame and to achieve simple manufacturing with 3D printing technology. Moreover, the octocopter PID controller was simulated on the Simulink environment to get performance on the roll and pitch angle control.Design/methodology/approachOctocopter is one kind of multirotor vehicle (a rotorcraft with more than two rotors), that has lately gained a lot of attention for both the scientific and commercial spheres. With a greater number of rotors, the multirotor is very maneuverable and robust. Multi-copter makes an important contribution to the technological revolution in the military, industry, transportation, mapping and especially agriculture. Nowadays, we are heading to the four-industrial revolutions as well as the new technological application in the agricultural field such as precision agriculture, mapping and surveillance. Due to recently advanced technology about sensors, electronics, 3D printing, battery with high performance, multi-copter can be manufactured at low cost.FindingsThe V-frame octocopter was chosen to design in this paper; it had better performance scores including high redundancy rotors, high payload capability and affordable cost than another multi-copter family. The V-frame octocopter increasing freedom field of view of the camera was considered to place the camera position in the front of the drone.Research limitations/implicationsFor the future aspects, the mechanical structure of the octocopter could be improved by using more advanced metal 3D printing to produce the aluminum or titan alloy materials for lighter and more rigid compared with ABS material, and finally the assembly to the real test.Originality/valueThe study shows the new platform of the V-frame octocopter kinematics analysis, designed on the CAD software, with some important mechanical parts using FEM analysis to find the highest stress and displacement under high load applied, the result of all connecting the joints 3D printing part is completely safe. Mechanical parts were manufactured by using 3D printing technology and CNC milling. Moreover, the study has shown V-frame octocopter simulation based on Simulink using the second method Ziegler- Nichols to find suitable parameters of the PID controller for roll and pitch angle. Using the block simulation is good for implementing and fast checking the new algorithm when building the new platform of the robot.
The relationship between corporate governance and cost of equity: evidence from the ISIS era in Iraq
Authors: Salehi Mahdi , Moradi Mahdi , Faysal Saad 
Published: January 2023

PurposeThe cost of equity (COE) and corporate governance structure are the most critical factors affecting competition among publicly held companies. Accordingly, the present paper aims to examine the relationship between corporate governance and the COE in the wake of the Islamic State of Iraq and Syria (ISIS) in Iraq.Design/methodology/approachOur statistical sample includes 34 companies listed on the Iraq Stock Exchange from 2012 to 2017. Board structure (i.e. board size, board independence, CEO tenure, board meetings frequency and CEO duality) and ownership structure (managerial ownership, institutional ownership and state ownership) are considered proxies for corporate governance structure. Besides, the authors employ the Capital Asset Pricing Model to measure the COE as our dependent variable. Multiple regression analysis and Exploratory Factor Analysis are also used to estimate the research models.FindingsOur results suggest that corporate governance structure plays a significant role in reducing COE during the ISIS era. Furthermore, the authors find that corporate governance can be an alternative to COE reduction in Iraq’s absence of national security. Our findings also indicate that board size, board meeting frequency, managerial ownership and institutional ownership are negatively associated with COE.Research limitations/implicationsAlthough this study has been thoroughly considered and cautiously planned, the specific period chosen to conduct the research (i.e. the ISIS era) could be a significant limitation since financial disclosure of listed companies may have been of lower quality during this period. However, to relatively alleviate this limitation and maintain the authenticity of the findings, the authors exclude low-quality financial statements, particularly non-audited financial reports, from the statistical sample. Furthermore, practitioners of emerging markets that are suffering from a weak external corporate governance combination can use the findings of this paper as a guideline to compensate the existing market deficiencies by improving internal corporate governance for observing further cash sources with lower cost. The findings also propose to international agencies that the business environment in Iraq is heavily affected by the ISIS phenomenon and needs financial aid to recover from its side effects. Furthermore, macroeconomists may use this paper to make more decisive macroeconomic indicators predictions.Originality/valueThis paper is among the pioneer investigations and elaborates on how the agency conflict is resolved effectively. The board and managerial characteristics and different forms of ownership might be applicable to provide cheaper funds for companies listed in emerging markets suffering from weak external corporate governance combinations.

Authors: Roy Paramita , Barua Anshuman 
Published: January 2023

PurposeThe purpose of this paper is to analyse the labour force participation among the elderly population (aged 60 and above) in India from data available for the most recent time periods. The paper reviews the types of employment, industries and occupations that the elderly in India are employed in presently and also examines the impact of different factors on the decision of the elderly to be a part of the labour force.Design/methodology/approachUnit-level data has been extracted from the most recent data available on employment and labour force in India provided by the Periodic Labour Force Survey (PLFS), from 2017 to 2018 to 2019–2020. Binary logistic regression model has been used to identify some of the socio-economic and demographic factors that influence the odds of the elderly being a part of the labour force along with the extent of their influence, and Wald statistic has been used to examine the dynamics.FindingsThe study finds that among the elderly population, males, individuals living in rural areas, those living alone, those who are currently married and those with low educational attainment are more likely to be a part of the labour force. Again, elderly females are found to be employed mostly in the informal or unorganised sector which provide minimal or nil social security benefits. Between 2017–2018 and 2019–2020, the coefficients for sector, gender, marital status, education and income are found to be significantly different.Originality/valueThis paper attempts to shed some light on the scanty literature with regards to studies on the elderly in India, and also to reveal the possible factors which induce the elderly in India to participate in the labour force with the help of the most recent data available.Peer reviewThe peer-review history for this article is available at: https://publons.com/publon/10.1108/IJSE-06-2021-0350.
Emphasizing effort vs talent in personal trainers' performance: consumption response of personal fitness training customers
Authors: Park Sangchul , Lee Hyun-Woo 
Published: January 2023

PurposeFitness service companies often promote the companies' personal training service by attributing trainers' competent characteristics, qualifications or/and service provision to their effort or talent. This promotion is called performance attribution promotion. Utilizing attribution theory and the theory's adjacent studies, this study investigated whether and why performance attribution promotion affects consumers' service purchase of personal fitness training.Design/methodology/approachThe authors developed the experimental stimuli of performance attribution promotion and validated those through a pretest (N = 200). Using the validated stimuli, the authors conducted an experiment with employing a single factor between-subject design (performance attribution promotion: effort vs talent) based on random assignment (N = 200).FindingsThe analysis results revealed that attributing trainers' competent characteristics, qualifications or/and service provision to effort (vs talent) leads to a higher level of service registration intention. Moreover, this effect was mediated by the perceived teaching expertise but not by the perceived teaching trustworthiness.Originality/valueThese findings enrich the literature by illuminating a new mechanism and consequence of performance attribution promotion. The authors' study also extends the marketing studies related to expertise perception by presenting the attribution of visible features as one of the characteristics determining expertise perception. Finally, the authors' findings also have implications for fitness service companies and other stakeholders that seek to effectively leverage trainers' competent outcomes for consumer acquisition.
