Inclination angle has been reported to have an enhancing effect on the thermal-hydraulic characteristics and entropy of some thermal systems. Therefore, this paper aims to numerically investigate the effects of inclination angle, volume concentration and Reynolds number on the thermal and hydraulic characteristics and entropy generation rates of water-based Al₂O₃ nanofluids through a smooth circular aluminum pipe in a turbulent flow.

A constant heat flux of 2,000 Watts is applied to the circular surface of the tube. Reynolds number is varied between 4,000 and 20,000 for different volume concentrations of alumina nanoparticles of 0.5%, 1.0% and 2.0% for tube inclination angles of ±90o, ±60o, ±45o, ±30o and 0o, respectively. The simulation is performed in an ANSYS Fluent environment using the realizable kinetic energy–epsilon turbulent model.

Results show that +45o tube orientation possesses the largest thermal deviations of 0.006% for 0.5% and 1.0% vol. concentrations for Reynolds numbers 4,000 and 12,000. −45o gives a maximum pressure deviation of −0.06% for the same condition. The heat transfer coefficient and pressure drop give maximum deviations of −0.35% and −0.39%, respectively, for 2.0% vol. concentration for Reynolds number of 20,000 and angle ±90o. A 95%–99.8% and 95%–98% increase in the heat transfer and total entropy generation rates, respectively, is observed for 2.0% volume concentration as tube orientation changes from the horizontal position upward or downward.

Research investigating the effect of inclination angle on thermal-hydraulic performance and entropy generation rates in-tube turbulent flow of nanofluid is very scarce in the literature.

The paper has a twofold purpose: (1) to test the application of means-end theory to providers of hospitality goods and services, and (2) to explore this question in the context of winery tasting rooms when they had a unique opportunity to restructure their hospitality experience due to government restrictions in response to COVID.

A qualitative approach was adopted, and a convenience sample was used to conduct semi-structured laddering interviews. Forty interview transcripts were coded as means-end ladders, which were analyzed using a custom computer program to develop the implication matrix and the hierarchical value map.

This paper demonstrates that means-end is a useful approach to investigate the values and behaviors of the producer, specifically hospitality hosts. It finds that the principal goal of tasting rooms is to generate sales, and offering a compelling guest experience is the characteristic that contributes the most to achieving that goal. The staff and the atmosphere created for the guests are the two factors with the greatest influence on the guest experience.

This is the first paper to use means-end theory to study the hospitality host, or the producer of goods and services in general, and the first to study winery hospitality primarily through the lens of means-end theory. The study also helps fill a gap in research on tasting room sales focused on the winery’s goals.

Guided by resource-based theory, this study unpacks the relationship between an export entrepreneurial marketing orientation (EMO) and export performance. This is undertaken by investigating quadratic effects and the moderating role of export coopetition (cooperation amongst competitors in an international arena).

Survey responses were collected from a sample of 282 smaller-sized wine producers in Italy. This empirical context was ideal, as it hosted varying degrees of the constructs within the conceptual model. Put another way, it was suitable to test the underlying issues for theorising purposes. The hypotheses and control paths were tested through a three-step hierarchical regression analysis.

An export EMO had a non-linear (inverted U-shaped) association with export performance. Furthermore, this link was positively moderated by export coopetition. With too little of an export EMO, small enterprises might struggle to create value for their overseas customers. With too much of an export EMO, owner-managers could experience harmful performance outcomes. By cooperating with appropriate industry rivals, small companies can acquire new resources, capabilities and opportunities to help them to boost their export performance. That is, export coopetition can stabilise some of the potential dangers of employing an export EMO.

The empirical findings signified that an export EMO has potential dark-sides if these firm-wide behaviours are not implemented effectively. Nevertheless, cooperating with competitors in export markets can alleviate some of these concerns. Collectively, unique insights have emerged, whereby entrepreneurs are advantaged by being strategically flexible and collaborating with appropriate key stakeholders to enhance their export performance.

This paper explores the way in which industrial pollution has been expressed in the narrative accounts of nature, landscape and industry by William Gilpin in his 18th-century picturesque travel writings. A positive description of pollution is generally outdated and unacceptable in the current society. The authors contrast his “picturesque” view with the contemporary perception of industrial pollution, reflect on these early accounts of industrial impacts as representing the roots of impression management and use the analysis to inform current accounting.

The research uses an interpretive content analysis of the text to draw out themes and features of impression management. Goffman's impression management is the theoretical lens through which Gilpin's travel accounts are interpreted, considering this microhistory through a thematic research approach. The picturesque accounts are explored with reference to the context of impression management.

Gilpin's travel writings and the “Picturesque” aesthetic movement, it appears, constructed a social reality around negative industrial externalities such as air pollution and indeed around humans' impact on nature, through a lens which described pollution as adding aesthetically to the natural landscape. The lens through which the picturesque tourist viewed and expressed negative externalities involved quite literally the tourists' tricks of the trade, Claude glass, called also Gray's glass, a tinted lens to frame the view.

The paper adds to the wealth of literature in accounting and business pertaining to the ways in which companies socially construct reality through their accounts and links closely to the impression management literature in accounting. There is also a body of literature relating to the use of images and photographs in published corporate reports, which again is linked to impression management as well as to a growing literature exploring the potential for the aesthetic influence in accounting and corporate communication. Further, this paper contributes to the growing body of research into the historical roots of environmental reporting.

The purpose is to investigate whether Brazilian e-commerce nonusers all have the same reasons not to purchase online or whether different behavior patterns might lead them to cluster in different groups.

This study carried out cluster analyses on a large sample (N = 9,065) from a nationwide survey on the use of information and communication technology in Brazil.

Three clusters of e-commerce nonusers were identified: the first cluster is quite reluctant; the second is characterized by disbelief in e-commerce; and the last cluster includes members who must see a product to believe it. Overall, nonusers have different reasons not to shop online, but they also share some similarities in this regard. Furthermore, socioeconomic factors do not seem to affect their behavior. The findings suggest that merchants’ failure to attract customers’ attention and tangibility are the major barriers to e-commerce use.

Even though nonusers have different reasons not to shop online, the key pattern that emerges is the value of tangibility for these individuals, which is a barrier present in all three clusters. This suggests that current marketing strategies and advertisements are ineffective to reach these consumers. Vendors should therefore try different approaches.

The findings contribute to the information systems (IS) literature by bringing a new perspective to the understanding of e-commerce rejection in addition to having managerial implications that involve strategies to attract potential users based on their specificities.

This study aims to investigate the extent to which the Indonesian conditional cash transfer (CCT), known as the Family Hope Program (FHP), impacts the probability of children engaging in labour activities.

This study utilizes data from the Indonesian Family Life Survey in 2014, focussing on periods following the implementation of the FHP. To estimate the impact of FHP on child labour in Indonesia, the authors employ a propensity score matching strategy to balance the characteristics observed between the participant and non-participant groups.

The estimates show that FHP has no statistical impact on child labour across all matching techniques. This implies that receiving the CCT does not always help poor households decrease the probability of stopping their children from participating in labour activities.

The conditions applied to the beneficiaries, which only require children to attend school without requiring them to stop working, may not effectively address the issue of child labour. The current structure and design of the FHP need to be re-evaluated and improved to effectively combat child labour.

Despite numerous studies examining the impact of CCT on child labour which remains inconclusive in Indonesia, this study contributes to the existing literature by considering children participating in labour activities across all types of work without focussing on specific education levels or regions.

The COVID-19 pandemic was an eye-opening experience that put to the test our crisis management competencies across many institutions, including those offered by institutions of higher education. This study aims to review the literature on international business (IB) risks and IB education (IBE) to question whether business graduates are equipped to make decisions in today’s volatile, uncertain, complex and ambiguous (VUCA) marketplace.

While the IB literature has discussed the importance of various sources of risks on global business operations, IBE did not effectively adopt an integrative approach to building the needed risk management competencies related to those risks into our education. The authors argue that this integrative approach to teaching IB is critically needed to prepare future global managers for addressing crises, like that of the pandemic and others. Specifically, this study proposes that this integrated risk management competency can be developed through the building of “synergistic mindsets”.

This study presents a conceptual framework for the components of the synergistic mindset, with intelligence that directly links to present IB risks. These components are cultural intelligence (CQ), emotional intelligence (EQ), public policy intelligence (PPQ), digital intelligence (DQ) and orchestration intelligence (OQ).

Insights related to IBE effectiveness in addressing today’s VUCA market demands and IB risks are discussed.

Consumer culture is promoting immediate gratification, and the rise of digital financial services is increasing the risk of indebtedness while debt reduces well-being and affects mental health. The authors assess the effects of consumer information provision, debt literacy, chronic debt and attitudes toward debt on the intent to purchase on credit.

An online survey including an experiment with a credit offer vignette was conducted in a representative sample of Estonia (n = 1204). Treatment conditions depicted either the total cost and duration of the credit agreement or the annual percentage rate.

Receiving modified information resulted in a 26 to 30 percentage points decrease in propensity to purchase on credit. Purchasing on credit was associated with attitudes towards credit and chronic debt, but not with debt literacy.

The findings reveal large effects of information provision and highlight the limited effects of debt literacy on credit decisions. Limitations may emerge from differences in financial regulation across countries.

The authors' results highlight the importance of applying behavioural insights in consumer credit information provision, both in the financial sector and policy. Testing the messages allows having evidence-based solutions that promote responsible purchasing on credit.

The findings call for changes in credit information provision requirements. Their effect is significantly larger compared to the literature, emphasizing the role of credit information provision in less regulated online markets.

This study aims to identify the role of consumer characteristics in cultural consumption tendencies. Additionally, the study examines whether country differences and prior experience in the country affect consumers' cultural consumption tendencies.

The effects of cosmopolitanism, consumer ethnocentrism, individual innovativeness, and lifestyle on cultural consumption tendencies were tested. Moreover, we assess whether country type and prior experience are differentiating factors for cultural consumption tendencies. To this end, two countries – the USA and South Korea, representing Western and Eastern cultures, respectively – were selected to achieve comparable results in two different cultures. The research data were collected from 775 people using an online survey method and analyzed using path analysis and an independent samples t-test.

Consumer characteristics affect cultural consumption tendencies. These effects are culture-specific and cultural product-specific. Cosmopolitanism has a positive impact on cultural consumption tendencies, while consumer ethnocentrism has a negative impact. Individual innovativeness and lifestyle partially affected cultural consumption tendencies. Notably, these effects differ by country type. However, cultural consumption tendencies do not differ according to consumers' prior experience.

This study provides insightful information for e-retailers to be mindful of global consumer characteristics. Accordingly, cultural consumption patterns can be used as the basis for market segmentation. In addition, understanding global consumer characteristics and their cultural product- and culture-specific effects on consumption will help cultural industry players in their segmentation and targeting decisions.

Notwithstanding the rich body of literature on cultural consumption, this study provides consumer-level comparative empirical research from a marketing perspective. Essentially, the study is novel as it reveals the consumer characteristics that affect cultural consumption tendencies.

The purpose of this Real Impact Research Article is to empirically explore one of the most controversial and elusive concepts in knowledge management research – practical wisdom. It develops a 10-dimensional practical wisdom construct and tests it within the nomological network of counterproductive and productive knowledge behavior.

A survey instrument was created based on the extant literature. A model was developed and tested by means of Partial Least Squares with data obtained from 200 experienced employees recruited from CloudResearch Connect crowdsourcing platform.

Practical wisdom is a multidimensional construct that may be operationalized and measured like other well-established knowledge management concepts. Practical wisdom guides employee counterproductive and productive knowledge behavior: it suppresses knowledge sabotage and knowledge hiding (whether general, evasive, playing dumb, rationalized or bullying) and promotes knowledge sharing. While all proposed dimensions contribute to employee practical wisdom, particularly salient are subject matter expertise, moral purpose in decision-making, self-reflection in the workplace and external reflection in the workplace. Unexpectedly, practical wisdom facilitates knowledge hoarding instead of reducing it.

Managers should realize that possessing practical wisdom is not limited to a group of select, high-level executives. Organizations may administer the practical wisdom questionnaire presented in this study to their workers to identify those who score the lowest, and invest in employee training programs that focus on the development of those attributes pertaining to the practical wisdom dimensions.

The concept of practical wisdom is a controversial topic that has both detractors and supporters. To the best of the author’s knowledge, this is the first large-scale empirical study of practical wisdom in the knowledge management domain.
