Authors: Niyibizi Bart , Brorsen B. Wade , Park Eunchun 
Published: October 2021

PurposeThe purpose of this paper is to estimate crop yield densities considering time trends in the first three moments and spatially varying coefficients.Design/methodology/approachYield density parameters are assumed to be spatially correlated, through a Gaussian spatial process. This study spatially smooth multiple parameters using Bayesian Kriging.FindingsAssuming that county yields follow skew normal distributions, the location parameter increased faster in the eastern and northwestern counties of Iowa, while the scale increased faster in southern counties and the shape parameter increased more (implying less left skewness) in southwestern counties. Over time, the mean has increased sharply, while the variance and left skewness increased modestly.Originality/valueBayesian Kriging can smooth time-varying yield distributions, handle unbalanced panel data and provide estimates when data are missing. Most past models used a two-stage estimation procedure, while our procedure estimates parameters jointly.
Effects of quantity promotional frames on inaction inertia
Authors: Liu Hsin-Hsien , Chou Hsuan-Yi 
Published: October 2021

PurposeInaction inertia is the phenomenon in which people are less likely to accept an opportunity after having previously missed a relatively superior one. This research explores how framing quantity promotions as either a freebie (e.g. “buy 1, get 1 free”) or a price bundle (e.g. “buy 2, get 50% off”) influences inaction inertia. Relevant mediators are also identified.Design/methodology/approachThree experiments, two using imaginary scenarios and one using an incentive-compatible design, test the hypotheses.FindingsConsumers who miss a freebie quantity promotion express higher inaction inertia than consumers who miss a price bundle promotion. The cause of this difference is higher perceived regret and greater devaluation that result from missing a superior freebie (vs price bundle) promotion.Research limitations/implicationsFuture research should examine how factors influencing perceived regret and devaluation moderate the quantity promotional frame effect on inaction inertia.Practical implicationsThe findings provide insights into which quantity promotional frames practitioners should use to reduce inaction inertia.Originality/valueThis study's comprehensive theoretical framework predicts quantity promotional frame effects on inaction inertia and identifies relevant internal mechanisms. The findings are evidence that inaction inertia is caused by both perceived regret and devaluation in certain contexts. Furthermore, this study identifies the conditions in which a price bundle promotional frame is more beneficial than a freebie promotional frame.
The impact of green finance and Covid-19 on economic development: capital formation and educational expenditure of ASEAN economies
Authors: Ngo Quang-Thanh , Tran Hoa Anh , Tran Hai Thi Thanh 
Published: October 2021

PurposeThe purpose of this study is to examine the impact of green finance (i.e. green investment, green security and green credit) along with capital formation and government educational expenditures on the economic development of (ASEAN) countries.Design/methodology/approachThe data were gathered from the central banks of all ASEAN countries and the World Bank Indicators between 2008 and 2019. The fixed-effect model and generalized method of moments were used to check the nexus between the constructs.FindingsThe results revealed that green finance along with capital formation and government educational expenditures have a positive association with the economic development of ASEAN countries.Research limitations/implicationsThe study carries some limitations, even though it addresses the underlying variables comprehensively. These limitations provide opportunities to future researchers and authors to expand the scope and accuracy of their study. This research investigation has been supported by the data collected from a single source. Though data collection is maintained correctly, it is still recommended to the upcoming scholars to acquire data to reconfirm the same findings using multiple data sources. The data collected from using some specific data source may be limited in scope and may hinder the comprehensive elaboration of the underlying variables and their mutual relationship. Therefore, the utilization of multiple sources of data collection gives data sufficient to meet the requirement of an okay quality research study. The study is about the economies of ASEAN countries. It checks the influences of green finance development on economic activities and the country's economic growth in ASEAN countries' economies. Thus, its results are valid only in the economies of these countries, and this research investigation lacks generalizability. For generalizability, the authors must consider the underlying variables in the world's vast economies. They must adopt a standard scale to judge the impacts of green financial development on economic development. Besides, the study analyzes the economic factors, economic conditions and their effects on the country's position in the world economy in the face of a severe epidemic like COVID-19. Thus, the results may be different in the case of the normal situation. So, a general standardized study is recommended to be conducted in the upcoming days.Originality/valueGreen finance has significant capability to improve the global economy, especially amidst the COVID-19 pandemic. This study is beneficial for policymakers to develop policies related to economic development with reference to green finance and also helps future research on a similar topic.
The influence of stacking technologies on structural dynamic properties of electric motors iron cores
Authors: Mönninghoff Sebastian , Jaeger Markus , Hameyer Kay 
Published: October 2021

Purpose
It is essential to understand the structural dynamic behavior of electrical machines to predict their acoustic and vibrational behavior. Stacking technology, which is used to manufacture soft magnetic cores, has a strong influence on the material properties. The purpose of this paper is therefore to research the influence of the stacking technologies welding and bonding with bake varnish on the modal properties of iron cores.

Design/methodology/approach
A finite element simulation model is developed based on homogenization of the stator core. Eigenfrequencies, modeshapes and modal damping ratios are extracted from measurements and are used to validate the simulation model.

Findings
Modal characteristics depend on the participation of certain material layers at a certain mode. Higher amount of shear deformation results in higher modal damping. Bonded stacks exhibit lower shear stiffness and higher damping ratios.

Originality/value
This research paper provides insights to the modal characteristics of iron cores used in electric machine and compares the influence of stacking technologies.
Quantifying costs of the productivity loss due to schedule changes in construction projects
Authors: Lee Jae-Seob 
Published: October 2021

PurposeThe purpose of the paper is to develop a method to integrate the schedule-based analysis with a productivity-based analysis to prove and support the result of the damages calculation.Design/methodology/approachIn this paper, a “cost and schedule impact integration” (CSI2) model is proposed to objectively show and estimate lost productivity due to changes in construction projects.FindingsA schedule-based analysis to include separate tracking of change order costs can be used to predict productivity due to the delay and disruption; changes in construction projects almost always result in delay and disruption. However, the schedule-based analysis needs to be integrated with a productivity-based analysis to prove and support the result of the damages calculation.Practical implicationsThe results of this study expand upon construction practices for proving and quantifying lost productivity due to changes in construction projects.Originality/valueThe contribution of the paper is summarized as the introduction of a “schedule impact analysis” into a “cost impact analysis” technique to assess the damages, as well as to demonstrate the labor productivity impact due to delay and disruption in construction projects.
The impact of entrepreneurship education and cultural context on entrepreneurial intentions of Ukrainian students: the mediating role of attitudes and perceived control
Authors: Mykolenko Olena , Ippolitova Inna , Doroshenko Hanna , Strapchuk Svitlana 
Published: October 2021

PurposeThe purpose of the research is to test empirically whether the variables of personal attitudes towards entrepreneurship and perceived control mediate the relationship between entrepreneurship education and intentions of Ukrainian students to become entrepreneurs; to determine whether personal attitudes mediate the relationship between cultural context and entrepreneurial intentions.Design/methodology/approachThe research project carried out jointly by four Kharkiv universities used 349 survey responses from senior students majoring in business and economics and management and marketing. The data was analysed using Partial Least Squares regression.FindingsEducation and employed teaching methods, in particular, positively affect students' attitudes towards entrepreneurship, their perceived capability to start a business and indirectly influence entrepreneurial intentions. However, attendance of entrepreneurship-related courses itself does not enhance perceived control and has no significant effect on personal attitudes. The study also shows that cultural context has a positive influence on students' attitudes towards entrepreneurship and, therefore, indirectly impacts their intentions to become entrepreneurs.Research limitations/implicationsFirstly, the students participating in the study were from one country. And secondly, the paper deals with pre-educational entrepreneurial intentions.Practical implicationsThe study suggests that a practice-based approach to entrepreneurship education is a key to raising entrepreneurial awareness of young people in countries whose national cultures are built on collectivist values.Originality/valueThe results of the study are of value for teaching staff, who can actually influence students' entrepreneurial self-awareness, and for university management in the context of contemporary education reforms and the latest requirements to education process.

Authors: Mehraliyev Fuad , Chan Irene Cheng Chu , Kirilenko Andrei Petrovich 
Published: October 2021

PurposeThis study aims to conduct a systematic review and critically analyze the sentiment analysis literature in hospitality and tourism from methodological (data sets and analyzes) and thematic (topics, theories, key constructs and their relationships) perspectives.Design/methodology/approachQualitative thematic review and quantitative systematic review were performed on 70 papers obtained from hospitality and tourism categories of two databases, namely, Web of Science and Scopus.FindingsA total of 5 topics and 27 sub-topics were identified and the major theme is market intelligence. Sentiment variables were investigated not only as independent but also as dependent variables. The customer rating is the most investigated dependent variable, whereas moderators and mediators were rarely tested. Most reviewed studies did not use theory. The findings from the methodological review show that analysis of big data was rare. Moreover, testing the performance of sentiment analyzes was uncommon, and only one paper tested the performance of aspect/feature extraction.Research limitations/implicationsThis study extends prior review studies by providing a comprehensive view of how knowledge and methodologies of sentiment analysis have developed. The identified themes and key constructs serve as a solid base for future knowledge advancement. Future research directions on sentiment analysis are also provided.Originality/valueTo the best of the authors’ knowledge, this study is the first comprehensive methodological and thematic review of sentiment analysis in hospitality and tourism. Based on the identified findings, the authors propose several directions for future research.
Image, eventscape, satisfaction and loyalty: a case study of a wine tourism event
Authors: Goncalves Olga , Camprubí Raquel , Fons Cendrine , Solonandrasana Bernardin 
Published: October 2021

PurposeEventscape is widely recognised as having played an important role in the image of wine events; however, research on this topic is scarce, with only a few studies examining the image of a wine tourism event. To date, no studies have examined eventscape and attitudinal variables of a wine event together, thus indicating a gap in the research. Further research to gain a deeper understanding of the role these factors play is needed; thus, this paper aims to explore the relationships between event image, eventscape, satisfaction and loyalty in wine events.Design/methodology/approachA structured questionnaire was chosen for data collection, with a final sample of 117 valid responses. Qualitative data was analysed by means of content analysis. Univariate and bivariate statistical analyses were performed to analyse eventscape attributes and explore its relationship with event image, satisfaction and loyalty.FindingsThe paper highlights that perceptions of eventscape are intrinsically related to perceived event image and reveal a statistically significant relationship between these two elements. Results show the importance of the social dimension in the image perception of a wine event and point to conviviality as the main element. This study also reveals a relationship between perceived event image and attitudinal variables and suggests that having a positive image of the event positively influences levels of satisfaction, which are higher, and willingness to participate in future editions of the event. Findings also reveal a relationship between event image and loyalty.Originality/valueWine-related events are undergoing significant developments, creating a need for competitive strategies to develop wine tourism and vineyards in certain regions. Research in this field is scarce to date; therefore, this paper adds to the literature by the studying consumer behaviour of attendees at wine events.

Authors: Rezaei Amirreza , Ahmadi Saba , Karimi Hamid 
Published: October 2021

Purpose
This study aims to determine the effect of online social networks on university students’ environmentally responsible behavior (ERB). This research aimed to develop and test a behavioral model in the context of online social networks, where students’ attitudes, knowledge and behavior influence their ERB.

Design/methodology/approach
This study used a quasi-experiment with a pretest-posttest design and a random parallelization control group. The research used a questionnaire to assess ERB, environmental attitudes and environmental knowledge. The researcher randomly assigned 120 students to an experimental and a control group of equal size. Both groups initially completed a pretest. The experimental group was trained in environmental issues over four months (an academic semester) via an online social network.

Findings
The findings indicated that the social network had a significant effect on motivating ERB. Additionally, it improved environmental attitudes. According to the results, online social networks such as Facebook can significantly aid in teaching and learning environmental issues in formal academic settings.

Originality/value
Online social networks facilitated significant cognitive progress in environmental education. The primary objective is to educate students about ERB.
The knock-on effects of green buildings: high-rise construction design implications
Authors: Blackburne Laura , Gharehbaghi Koorosh , Hosseinian-Far Amin 
Published: October 2021

PurposeThe aims and objectives of this research are to establish whether or not the transition into green building in high-rise construction is practical. This is after considering several perspectives including financial, economic, environmental, and social. This subsequently leads to an evaluation on whether or not the continuation with a standard conventional build of high-rise buildings remains to be the most feasible option. Such objectives, therefore, aim to allow for validation of how and why high-rise construction designs are impacted through green buildings effects.Design/methodology/approachThrough six defined steps, the methodology commences with an introductory section of what it means to build green. This section is further broken down to evaluate what factors are involved in constructing a green building. Furthermore, the life cycle energy (LCE) is used as a framework to evaluate the knock-on effects of green buildings and subsequent high-rise construction design implications.FindingsThrough defining the ongoing relationship of green materials and sustainable design, various implications for high-rise constructions were discovered. First and foremost, it was determined that the LCE is the central consideration for any high-rise building design. In evaluating the LCE, and overall operating energy of the 50-year cycle of a building was carried out. As the results showed, the operating energy represents around 85% of the total energy that is consumed at the end of the 50 years cycle of the building. Precise LCE calculation can lead to a more efficient design for high-rise buildings. As a result, an increased understanding of the current status of green buildings within the construction industry is paramount. This understanding leads to a better insight into the contributing factors to green building in high-rise construction and the construction industry in general.Originality/valueThe potential contribution that can be gained from this research is the awareness that is raised in the research and development of green buildings in high-rise construction. This can be achieved by using certain materials such as new energy-efficient building materials, recycled materials and so on. This research will contribute to defining a new way of sustainable buildings, particularly for high-rise construction. The outcome of the research will be beneficial for practitioners such as design engineers and other related professions.
Cognitive and affective predictors of occupational stress and job performance: the role of perceived organizational support and work engagement
Authors: Junça Silva Ana , Lopes Cannanda 
Published: October 2021

PurposeThis study aimed to (1) analyze whether the perceived organizational support (POS) was a significant predictor of performance and stress and (2) explore the mediating role of engagement in these relations.Design/methodology/approachTo test the hypotheses, the authors collected data with 200 working adults in a mandatory quarantine due to COVID-19 pandemic crisis.FindingsThe results showed that the POS contributed to increase engagement, and consequently, job performance. These relations also proved to be significant for stress, because when the POS increased, the work engagement also increased, and as a result decreased occupational stress.Research limitations/implicationsThis study relied on a cross-sectional design. Therefore, future research should consider a daily design to replicate this study and analyze daily fluctuations. Overall, the authors can conclude that work engagement is an affective process through which POS decreases stress and increases performance.Originality/valueThis study tests the mediating effect of work engagement on the link between POS, stress and performance, and its theoretical and practical implications of these findings are discussed.

Authors: Saeed Meo Muhammad , Jameel Kiran , Chowdhury Mohammad Ashraful Ferdous , Ali Sajid 
Published: October 2021

PurposeThe purpose of the research is to analyze the impact of world uncertainty and pandemic uncertainty on Islamic financial markets. For representing Islamic financial markets four different Islamic indices (DJ Islamic index, DJ Islamic Asia–Pacific index, DJ Islamic-Europe index and DJ Islamic-US) are taken.Design/methodology/approachThe study employs quantile-on-quantile regression approach to see the overall dependence structure of variables based on quarterly data ranging from 1996Q1 to 2020Q4. This technique considers how quantiles of world uncertainty and pandemic uncertainty asymmetrically affect the quantiles of Islamic stocks by giving an appropriate framework to apprehend the overall dependence structure.FindingsThe findings of the study confirm a strong negative impact of world uncertainty and world pandemic uncertainty on regional Islamic stock indices but the strength of the relationship varies according to economic conditions and across the regions. However, the world pandemic effect remains the same and does not change. Conversely, pandemic uncertainty has a larger effect on Islamic indices as compared to world uncertainty.Practical implicationsOur findings have significant implications for investors and policymakers to take proper steps before any uncertainty arise. A coalition of the central bank, government officials and investment bank regulators would be needed to tackle this challenge of uncertainty.Originality/valueTo the best of the authors' knowledge, none of the current works has considered the asymmetric impact of world and pandemic uncertainties on Islamic stock markets at both the bottom and upper quantiles of the distribution of data.
