Abstract

Purpose

The purpose of this study is to advance the understanding of consumer innovativeness during aging. This study explores why older consumers have decreased innovativeness and how awareness of age-related change affects the adoption of innovation.

Design/methodology/approach

A survey was conducted on 200 older consumers aged 50 and older to investigate whether awareness of age-related change influences innovativeness.

Findings

The results show that awareness of age-related change causes older consumers to have a decreased tendency to adopt novel products. Moreover, the stereotype threat of older consumers is found to play a mediating role. Older individuals who sense they are negatively viewed as older people restrict their innovativeness to avoid situations that would confirm their incompetence to others. Furthermore, the effects of older consumers’ stereotype threat on innovativeness are moderated by self-monitoring. Older consumers who exhibit high self-monitoring cope with stereotype threat by showing increased innovativeness; however, the opposite effect occurs in older consumers with low self-monitors.

Originality/value

The findings deepen the understanding of older adults’ consumption behavior regarding innovative products and show why people are reluctant to adopt innovative products and services because they grow older by identifying the underlying process that hinders customer innovativeness.

Abstract

This chapter extends the univariate forecasting method proposed by Wang, Luc, and Hsiao (2013) to forecast the multivariate long memory model subject to structural breaks. The approach does not need to estimate the parameters of this multivariate system nor need to detect the structural breaks. The only procedure is to employ a VAR(k) model to approximate the multivariate long memory model subject to structural breaks. Therefore, this approach reduces the computational burden substantially and also avoids estimation of the parameters of the multivariate long memory model, which can lead to poor forecasting performance. Moreover, when there are multiple breaks, when the breaks occur close to the end of the sample or when the breaks occur at different locations for the time series in the system, our VAR approximation approach solves the issue of spurious breaks in finite samples, even though the exact orders of the multivariate long memory process are unknown. Insights from our theoretical analysis are confirmed by a set of Monte Carlo experiments, through which we demonstrate that our approach provides a substantial improvement over existing multivariate prediction methods. Finally, an empirical application to the multivariate realized volatility illustrates the usefulness of our forecasting procedure.

Abstract

Purpose

The purpose of this paper is to identify the effects of algorithm teaching on the problem-solving skills of deaf-hard hearing students.

Design/methodology/approach

In this research, a pre-test and post-test problem-solving scale was applied to the single group (16 deaf-hard hearing students at a secondary school level) that had received algorithm education. Pre-test and post-test results were compared in order to see whether there was a significant difference among students in terms of their problem-solving attitudes. Students’ levels of performing the applications were examined through observation forms and their opinions about algorithm teaching were received.

Findings

As a result of the research, it was determined that implemented algorithm teaching had a significant effect on improving the problem-solving skills of the students.

Originality/value

Scratch training can be administered as either a compulsory or an optional course for hearing students as the Scratch programme offers the opportunity of teaching algorithmic reasoning with games, making the courses entertaining and giving students the chance to create their own designs which helps to improve their creative problem-solving skills and their motivation accordingly. Scratch teaching can be beneficial in developing students’ problem-solving behaviours and creativity.

Abstract

Purpose

Heeding the call for insights into the Sub-Saharan African international marketing context, this study aims to empirically examine consumers' desires and motivations for buying counterfeit luxury goods. It examines influences on consumers' attitudes and purchase intentions related to counterfeit luxury goods in Rwanda, one of Sub-Saharan Africa's fastest-growing economies and growing luxury markets, developing and testing a model examining the effect of social context on personal attributes, providing evidence on economic and social-status factors as drivers for counterfeiting.

Design/methodology/approach

The data were collected using an online survey administered in Rwanda to consumers who had previously purchased luxury goods and counterfeits. A total of 312 valid responses were analyzed using structural equation modeling.

Findings

This study found that normative and informational influences had a positive effect on Rwandan consumers' attitude toward purchasing counterfeit luxury products, with attitude influencing purchase intentions directly and indirectly, through mediating variable desire for status or through value consciousness and desire for status.

Originality/value

The study contributes to academic research − one of the first empirical studies to examine consumers' desires and motivations for buying counterfeit luxury goods in Sub-Saharan Africa, providing insights that benefit scholars and practitioners seeking to better understand a market where more than half of the world's fastest economies are located.

Abstract

Purpose

Individuals’ daily leisure activities undertaken close to home often appear in tourism contexts when individuals are away from home. Previous studies have suggested that such leisure-tourism connection behaviors are enhanced by leisure involvement and leisure habits. However, few studies have examined if such a connection may have variations by life stage and gender. Therefore, this study aims to examine the roles of life stage and gender in consistency between leisure and tourism, in consideration of involvement and habit. The study samples were university graduates (n = 681) who had graduated from a university in the United States and were currently working and university students (n = 706) who were enrolled and taking classes at a university in the United States.

Design/methodology/approach

Data were analyzed using descriptive analysis, exploratory factor analysis, t-test, two-way ANOVA and multiple regression analysis.

Findings

The findings revealed differences in the effects of leisure involvement and habit factors on the leisure-tourism connection behaviors by life stage and gender. More details are presented in this paper.

Originality/value

This study is the first study to examine the leisure-tourism connection behaviors in consideration of life stage and gender.

Abstract

Purpose

This paper examines dynamic return spillovers and connectedness networks among international stock exchange markets. The authors account for asymmetry by distinguishing between positive and negative returns.

Design/methodology/approach

This paper employs the spillover index of Diebold and Yilmaz (2012) to measure the volatility spillover index for total, positive and negative volatility.

Findings

The results show time-varying and asymmetric volatility spillovers among the stock markets under investigation. During the coronavirus disease 2019 (COVID-19) pandemic, bad volatility spillovers are more pronounced and dominated over good volatility spillovers, indicating contagion effects.

Originality/value

The presence of confirmed COVID-19 cases positively (negatively) affects the good and bad spillovers under low and intermediate (upper) quantiles. Both types of spillovers at various quantiles agree also influenced by the number of COVID-19 deaths.

Abstract

Purpose

The purpose of this paper is to establish a model‐based framework allowing the simulation, analysis and optimization of friction stir welding (FSW) processes of metallic structures using industrial robots, with a particular emphasis on the assembly of aircraft components made of aerospace aluminum alloys.

Design/methodology/approach

After a first part of the work dedicated to the kinetostatic and dynamical identification of the robotic mechanical system, a complete analytical model of the robotized process is developed, incorporating a dynamic model of the industrial robot, a multi‐axes macroscopic visco‐elastic model of the FSW process and a force/position control unit of the system. These different modules are subsequently implemented in a high‐fidelity multi‐rate dynamical simulation.

Findings

The developed simulation infrastructure allowed the research team to analyze and understand the dynamic interaction between the industrial robot, the control architecture and the manufacturing process involving heavy load cases in different process configurations. Several critical process‐induced perturbations such as tool oscillations and lateral/rotational deviations are observed, analyzed, and quantified during the simulated operations.

Practical implications

The presented simulation platform will constitute one of the key technology enablers in the major research initiative carried out by NRC Aerospace in their endeavor to develop a robust robotic FSW platform, allowing both the development of optimal workcell layouts/process parameters and the validation of advanced real‐time control laws for robust handling of critical process‐induced perturbations. These deliverables will be incorporated in the resulting robotic FSW technology packaged for deployment in production environments.

Originality/value

The paper establishes the first model‐based framework allowing the high‐fidelity simulation, analysis and optimization of FSW processes using serial industrial robots.

Abstract

The purpose of this paper is to show how XML is applied to digital library systems. For a better understanding of XML, the major features of XML are reviewed and compared with those of HTML. An experimental XML‐based metadata retrieval system, which is designed as a subsystem of the Korean Virtual Library and Information System (VINIS) is demonstrated. The metadata retrieval system consists of two modules: a retrieval module and a browsing module. The retrieval module allows the retrieval of metadata stored in Microsoft Access files and the display of search results in an XML file format, while the browse module permits browsing of metadata in XML/XSL document formats. Finally, some issues for a more efficient application of XML to digital libraries are discussed.

Abstract

Purpose

Paint drying is a very important process in an industry where shorter drying time for productivity and lower energy consumption for production cost are required while maintaining the product’s painting quality. In the present study, a drying process in a line-type paint drying furnace equipped with nozzles for hot air supply and moving conveyer belt to dry painted automotive parts is numerically simulated for the flow and heat transfer inside the furnace to evaluate the quality of the drying or baking at the end of the drying process in a production line.

Design/methodology/approach

A baking window for a specific paint is used for judging the local degree of baking (DOB) of the painted parts, which can be useful to identify under-baked or over-baked locations of the painted parts, and hence the quality of the baking process.

Findings

Numerical results of a time history of temperatures at two monitoring points on the painted parts were obtained and compared to the measured data in an actual furnace and showed good agreement. Three types of paints were considered in the present study and numerical results showed different drying characteristics. In addition to the original furnace nozzle configuration, two more furnace nozzle configurations with different numbers, direction and speed of hot air supply were simulated to improve the furnace’s drying performance. As a result, a newly suggested nozzle configuration with quick drying paint can give us a remarkable improvement in surface averaged DOB compared to the original nozzle configuration with original paint.

Originality/value

The present simulation technique and DOB methodology can be used for the optimal design of a drying furnace.

Abstract

This study proposes a conceptual model to comprehensively understand how sports fans perceive and accept smartphones and applications in a sport consumption context by developing a series of propositions. Theoretically based on the Technology Acceptance Model (TAM) and the Sport Website Acceptance Model (SWAM), this study provides fundamental groundwork to better conceptualise sports fans' decision making processes involving the latest technology used to consume sport.
