The purpose of this research is to address the existing gap in the study of construction and demolition waste (C&DW) by focusing on its impact on human health throughout the entire life cycle. And this research provides a comprehensive assessment model that incorporates the release of gaseous pollutants and particulate matter during the whole life cycle of C&DW, thereby contributing to a more holistic understanding of its impact on human health.

The research was conducted in two stages. Firstly, the quantitative model framework of pollutants emitted by C&DW was established. Three types of pollutants were considered, namely nitrogen dioxide (NO₂), sulfur dioxide (SO₂) and inhalable particulate matter (PM10). Second, disability-adjusted life year (DALY) and willingness to pay (WTP) assessments were used to provide a monetary quantified health impact for pollutants released by C&DW.

The results show that the WTP value of PM10 is the highest among all pollutants and 8.68E+07 dollars/a, while the WTP value in the disposal stage accounts for the largest proportion compared to the generation and transportation stage. These findings emphasize the importance of PM10 and C&DW treatment stage for pollutant treatment.

The results of this study are of great significance for the management department to optimize the construction management scheme to reduce the total amount of pollutants produced by C&DW and its harm to human health. Meanwhile, this study fills the gap in existing research on the impact assessment of C&DW on human health throughout the whole life cycle, and provides reference and basis for future research and policy formulation.

As information technology advances, the prevalence of AI chatbot products is on the rise. Despite optimistic market projections, consumer skepticism towards these agents persists. This paper aims to expand the scope of the technology acceptance model by integrating the aspect of appearance. It examines the influence of different attributes of AI chatbot, such as usefulness, ease of use and appearance, individually and in combination, on consumers' intentions to share and purchase.

Using an exploratory study of Web Texts, a 2 (usefulness: high vs low) × 2 (ease of use: high vs low) mixed design and a 2 (usefulness: high vs low) × 2 (ease of use: high vs low) × 2 (anthropomorphism appearance: humanoid vs cartoon) for between-subjects designs and the price level (high vs low) for within-subjects designs. The hypotheses were tested by Octoparse and SPSS 22.0.

The research highlights the significant role of usefulness, ease of use and anthropomorphic appearance in shaping consumer attitudes towards AI chatbots, thus influencing their intentions to share information and make purchases. Grouped regression analysis reveals that lower prices exert a more pronounced positive influence on consumers' inclinations to both share and purchase, compared to higher prices. Moreover, novelty-seeking behavior moderates the effect of perceived usefulness or ease of use on attitude. Specifically, heightened novelty-seeking tendencies mitigate the impact of low perceived usefulness or ease of use, leading to sustained positive attitudes towards AI chatbots among consumers.

This study innovatively incorporates product appearance into the Technology Acceptance Model (TAM), considering both the functional attributes and appearance of AI chatbot and their impact on consumers. It offers valuable insights for marketing strategies, extends the scope of TAM application and holds significant practical implications for enhancing enterprise product planning.

随着信息技术的进步, AI聊天机器人产品的普及正在增长。尽管市场对这些代理人持乐观态度, 但消费者对这些代理人的怀疑仍然存在。本文旨在通过整合外观方面来扩展技术接受模型的范围。它考察了AI聊天机器人的不同属性（如有用性、易用性和外观）对消费者分享和购买意图的影响, 单独以及组合。

使用Web文本的探索性研究, 一个2（有用性：高vs低）× 2（易用性：高vs低）的混合设计和一个2（有用性：高vs低）× 2（易用性：高vs低）× 2（人格化外观：类人形vs卡通）用于受试者间设计和价格水平（高vs低）用于受试者内设计。通过 Octoparse 和 SPSS 22.0 测试假设。

研究突出了有用性、易用性和拟人化外观在塑造消费者对AI聊天机器人态度方面的重要作用, 从而影响了他们分享信息和购买的意图。分组回归分析显示, 相对于高价格, 低价格对消费者分享和购买的倾向产生了更为显著的正面影响。此外, 新奇寻求行为调节了感知有用性或易用性对态度的影响。具体来说, 增强的新奇寻求倾向减轻了对低感知有用性或易用性的影响, 导致消费者对AI 聊天机器人持续保持积极态度。

本研究将产品外观创新地纳入技术接受模型（TAM）中, 考虑了AI 聊天机器人的功能属性和外观以及它们对消费者的影响。它为营销策略提供了有价值的见解, 拓展了TAM的应用范围, 并对增强企业产品规划产生了重要的实际影响。

The purpose of this paper is to examine the key practical factors that confront global businesses as they attempt to improve all aspects of their operations including emerging areas of the customer experience. The paper focuses on the way various organisational capabilities such as information systems/information technology have been adopted in order to provide an enhanced operational and strategic control over key areas of business.

The paper adopts a case‐based participation observation study which explores the global operations of a major restaurant brand. This approach enables it to explore several concepts which examine the behaviour of global operations at a time of major change.

The paper has focused on the application of change principles in the restaurant and hospitality industry and its importance for business performance and marketing strategy. The paper shows how adapting business strategy to incorporate key cultural sensitivities can pay major dividends for organisations. This strategy appears to be contrary to the general approach of standardisation adopted by other franchises in this key market sector.

It will be necessary to increase the range of this research to ensure any real certainty regarding its implications.

The paper identifies a number of interesting changes to preconceived ideas of standardising product portfolios in the restaurant sector. It shows the need for a balanced “mix” of menu products to satisfy local and national requirements.

The purpose of this paper is to argue for the merits of design thinking as an approach to develop a content and language integrated learning (CLIL) course in hospitality education. This argument is primed to address the dynamic and ever-changing landscape of the tourism and hospitality industry prompts educators to emphasize on learners developing industry-readiness outcomes through integrating innovative methods.

A quasi-experimental approach was used to examine how design thinking enhances industry-ready competencies. A two-phase self-administered survey on design thinking and added instructional design were facilitated at the beginning of the semester and subsequently close to the end of the semester. Follow-up interviews were also conducted to give more meaning on the matter.

Findings of this study reveal that problem-solving, critical thinking, teamwork and communication skills were enhanced as a result of integrating two teaching components related to design thinking.

This paper articulates the important and valuable role of design thinking to hospitality curriculum and provides tangible outcomes to explain how such a technique may be mapped onto a CLIL course.

This study aims to focus on providing a computerized classification testing (CCT) system that can easily be embedded as a self-assessment feature into the existing legacy environment of a higher education institution, empowering students with self-assessments to monitor their learning progress and following strict data protection regulations. The purpose of this study is to investigate the use of two different versions (without dashboard vs with dashboard) of the CCT system during the course of a semester; to examine changes in the intended use and perceived usefulness of two different versions (without dashboard vs with dashboard) of the CCT system; and to compare the self-reported confidence levels of two different versions (without dashboard vs with dashboard) of the CCT system.

A total of N = 194 students from a higher education institution in the area of economic and business education participated in the study. The participants were provided access to the CCT system as an opportunity to self-assess their domain knowledge in five areas throughout the semester. An algorithm was implemented to classify learners into master and nonmaster. A total of nine metrics were implemented for classifying the performance of learners. Instruments for collecting co-variates included the study interest questionnaire (Cronbach’s a = 0. 90), the achievement motivation inventory (Cronbach’s a = 0. 94), measures focusing on perceived usefulness and demographic data.

The findings indicate that the students used the CCT system intensively throughout the semester. Students in a cohort with a dashboard available interacted more with the CCT system than students in a cohort without a dashboard. Further, findings showed that students with a dashboard available reported significantly higher confidence levels in the CCT system than participants without a dashboard.

The design of digitally supported learning environments requires valid formative (self-)assessment data to better support the current needs of the learner. While the findings of the current study are limited concerning one study cohort and a limited number of self-assessment areas, the CCT system is being further developed for seamless integration of self-assessment and related feedback to further reveal unforeseen opportunities for future student cohorts.

Many groups in organisations are unsuccessful in problem solving. However, the principle of continuous improvement necessitates that organisations refine their employees’ problem-solving skills. In this mixed-method, field-based lab experiment, we explored the impact of a treatment to enhance the quality of group problem-solving processes.

We focused on the structured problem-solving process in Kaizen Events by differentiating six consecutive phases. About 16 Kaizen Event groups (101 members) participated in a field-based lab experiment that used a lean simulation game to establish a group problem-solving context. Data were collected via video, surveys and group interviews. We examined if a high-quality process is strengthened through group members’ elevated awareness of problem-solving preferences. About 11 groups received a treatment of tailor-made individual feedback to increase awareness of their problem-solving preferences. Additionally, we repeated the experiment in five control groups, where member preferences were not shared.

In the treatment groups, where problem-solving preferences had been shared, we observed a clear improvement in Kaizen Event process quality and higher problem-solving self-efficacy levels. Moreover, their self-reported Kaizen Event behaviour had changed. Within the control groups, the participants also reported that their problem-solving self-efficacy had improved, but this did not have a positive impact on the quality of the objectively measured Kaizen Event process.

By combining insights from operations management and organisational behaviour, we demonstrate that the structured Kaizen Event problem-solving process improves when group members’ individual problem-solving preferences are shared. We thus add an individual-level variable to the extant models of Kaizen Event success factors. Our results provide fresh insights into how to improve the continuous improvement process within organisations. Kaizen Event stakeholders and their facilitators are offered guidance on how to increase one’s awareness of own and others’ problem-solving preferences in group-based problem-solving events.

This study aims to solve the premature failure of the rubber stator due to wear, reduce the frictional resistance moment of the screw pump to solve the problem of a model of Daqing oilfield screw pump oil recovery system shutdown after the difficult start.

For the first time, the rotor surface of a screw pump was treated with dot-matrix texture to study the effect of dot matrix texture on the tribological performance of the stator-rotor friction subsets of screw pump. Reciprocating friction tests with different texture morphologies (S-shape, double tongue) and angular parameters (0°, 45° and 90°) were conducted at 10% of the texture area and pump silicone grease.

When point texture was added to the surface of the rotor sample, the friction coefficient and wear quantity of the sample were lower than those of the surface without texture treatment, and the double tongue 0° combination showed the best tribological properties. At this time, the average coefficient of friction and wear is reduced by 22.8% and 62%, 28.6% and 64.8%.

The introduction of texture can effectively improve the tribological performance of progressive screw pumps, and this paper provides important theoretical and experimental support for the design of progressive screw pumps in practical applications.

Gamification has been studied in many areas, i.e. marketing, education, training, and psychology. There has been an increased interest in the topic of gamification among scholars in the past several years. The purpose of this paper is therefore to use citation network analysis and explore changes in scholarly interest in the topic of gamification. As a result, four study hypotheses were developed: H1a: the “other” category publications (books, proceedings, etc.) will have a significantly larger frequency when compared with “journal” publications; H1b: the trend line of the frequency of publications will most closely fit the S-curve of Adoption in the adoption of innovations or the spread of new ideas as postulated by Rogers (2003); H2a: there will be a negative correlation between graph density and the number of vertices (publications); and H2b: there will be a positive correlation between average geodesic distance (AVGD) and the number of vertices (publications).

Data were collected from three searches for all published works that contained the word “gamification” in the titles of publication (the unit of analysis) from 2010 to 2013. The sampling was conducted via Google Scholar, amazon.com, and the academic library databases, i.e. EBSCO Search, JStor Scholarly Journal Archive, PsychArticles, and WorldCat. Data were analyzed using frequency counts and citation network. NodeXL is a highly structured workbook that includes multiple worksheets and computational functions necessary to store, represent, and analyze a network.

All four hypotheses were supported; the “other” category accounted for a significantly larger number of publications with the word “gamification” in the title; the trend line of the frequency of publications will most closely fit the S-curve of Adoption in the adoption of innovations or the spread of new ideas as postulated by Rogers (2003); there was a negative correlation between graph density and the number of vertices (publications); and there was a positive correlation between AVGD and the number of vertices (publications).

It is highly improbable that a “pure” or “random” sample of publications could be collected because it is highly probable that there exists no known, i.e. identifiable and verifiable “true” population of works that include gamification in the title.

The study findings have three major implications. The first takes in scholarly communication and the development of scientific knowledge. The findings imply that scholarly communication follows patterns similar to the adoption of innovation. The second implication deals with the topic known as “gamification.” The study findings imply that scholars believe gamification is worthy of serious study as the network of scholars studying gamification is increasing. The third implication of our study relates to the methods used to study scholarly communication. The study findings imply that network analysis can be used to understand how a new concept can be vetted by the scientific community.

The citation network analysis of this study provided tangible evidence of how new concepts are vetted, i.e. adopted. Citation network studies thus offer promise for a deeper understanding of scholarly communication and the adoption of new research topics and fields of inquiry. In addition, the findings indicate that “gamification” is a potentially fruitful topic for scholars to continue to explore.

Corporate social responsibility (CSR) is viewed as a differentiating strategy that wins over stakeholders’ confidence. Due to the potential strategic and positive effects on businesses, the study of CSR and its relationship to competitiveness has gained relevance. While studies have examined the impact of CSR activities on firm competitiveness, the findings so far remain contradictory. Further research on the underlying processes/mechanisms that explain how CSR contributes to competitiveness remains scarce. Accordingly, this study aims to look into the link between CSR and competitiveness with a focus on Asian business and management studies.

By using a bibliometric approach, this paper aims to provide a review of the state-of-the-art research on the linkage between CSR and competitiveness in Asian context. The sample for this research included all 538 studies from the period of 2001–2023 in the Scopus database. A bibliometric study included both co-occurrence and co-citation analysis.

The study’s findings made significant contributions by identifying seven distinct clusters of co-occurrences. Using co-citation, three journals-based co-citation clusters and another three authors-based co-citation clusters are identified. The findings show how processes/mechanisms such as – accountability, multi-stakeholder dialogue/engagement, resource generation, emphasizing sustainable development goals and emerging markets, redefining strategy, cultivating value/vision and CSR leadership – are increasing in importance.

Overall, the authors argue that CSR-led competitiveness is indeed one of the key drivers for improved sustainability performance of a firm.

Based on findings, a conceptual framework has been proposed highlighting different processes and mechanisms that influence the CSR-led competitiveness – outcomes relationship.

The purpose of this paper is to investigate the impact of family communication patterns (FCPs) on adolescents’ choice of conflict resolution strategies during family holiday planning.

The paper is framed by and builds on the literature on the adolescents’ choice of conflict resolution strategies and the FCP. The sample was collected using a survey among 400 adolescents in India. Exploratory factor analysis, confirmatory factor analysis and structural equation modelling have been used to analyse the data.

The paper provides a significant relationship between FCP and the choice of conflict resolution strategies. The study findings suggested that adolescents’ choice of resolution strategy depends on the type of communication environment in the family. It has been seen that adolescents have more say in concept-oriented families and use different types of resolution strategies compared to socio-oriented families.

The present study has considerable implications for the marketers and the academicians. Through FCP, marketers will be able to segment the families and, hence, may introduce efficient and competent marketing strategies and promotional campaigns.

The paper offers insights into the choice of conflict resolution strategy by adolescents’ in different FCPs. The study has originality and offers value to marketers as it focuses on adolescents, and explores their perceptions about their influence during the decision process.
