The Internet has introduced new ways of conducting business. Online auction of nonperishable experience goods (NPEG) items, which are generally rare, expensive and durable and need to be experienced to be valued, is one area that is undergoing significant change. Online auction platforms are encouraging participants to interact publicly in a social media type comment format. This paper investigates how such public interactions impact the auction outcomes of NPEG.

Auction records of vintage automobiles sold between 2015 and 2023 on one of the biggest online auction platforms in the USA were collected. The dataset contains multiple variables per record such as winning bid price, number of comments by sellers and browsers and various details of the automobile, for example brand, vintage and mileage. Ordinary least squares was utilized to analyze close to 42,000 records in the dataset.

The paper found that comments in general are positively correlated with the winning bid; it also found that online buyers value browser comments higher than seller comments. Furthermore, the relationship between vintage and origin country and winning bid is enhanced by browser comments.

This research furthers theory on two fronts. Firstly, we analyze how auction outcomes are impacted when buyers, casual observers and sellers interact with each other publicly when the auction is ongoing. To the best of the author's knowledge, this is one of the first studies that delve into participant interactions in online ongoing auctions. Secondly, we investigate how potential buyers utilize participant interaction information to guide their decisions about the value of NPEG.

In industrial buyer–supplier relationships, being an attractive customer has been found to result in superior supplier performance. However, there is a limited understanding of how these benefits transfer to the public domain. This study aims to explore the influence of customer attractiveness on supplier resource mobilization efforts toward the public sector.

A qualitative approach was used, focusing on in-depth interviews with 23 informants from 3 critical and complex supplier markets. The data were processed using inductive coding and thematic analysis.

The findings indicate that customer attractiveness in the public sector influences suppliers’ mobilization efforts on several dimensions. In addition to stimulating competition in the tender phase, customer attractiveness can yield important benefits to quality, supply stability and innovation during the business relationship. It appears imperative for the public sector to improve its standings with suppliers to both mitigate the apparent risk of sub-par treatment and to unlock the preferential supplier treatment associated with being an attractive customer.

Receiving increased mobilization from suppliers will result in better use of public money and help improve resilience and innovation in public procurement.

This study extends the research on customer attractiveness in the public sector by being the first to explore the range and nature of its influence on supplier mobilization efforts.

This paper aims to investigate the influence of scan speed on the corrosion and tribocorrosion features of the CoCrMoW samples fabricated via the selective laser melting (SLM) process.

CoCrMoW samples were produced by SLM at different scan speeds. Produced samples were made via structural surveys (X-ray diffraction examinations and scanning electron microscopic analyses), hardness measurements and electrochemical and tribocorrosion experiments.

Outcomes displayed that the corrosion and tribocorrosion properties of CoCrMoW alloy were significantly influenced by scanning speeds. Also, these properties of the alloy increased with increasing scanning speeds. CoCrMoW samples produced at a laser scan speed of 1,000 mm/s showed the best resistance to corrosion and tribocorrosion. This could be related to the high hardness and low grain structure of the fabricated samples.

This paper may be a practical reference and offers insight into the effect of scanning speeds on the increase of hardness, tribological and corrosion performance of CoCrMoW alloys. This study can help in the further advancement of cobalt-chromium alloy in situ produced by SLM for both electrochemical and tribocorrosion behavior for biomedical applications.

The current study seeks to explore the links between principal self-efficacy, openness to change, well-being, and transformational leadership. Specifically, we tested a mediated-effects model where principal self-efficacy and openness to change were treated as independent variables, well-being as mediator, and transformational leadership as dependent variable.

Survey data were collected from 351 principals employed in Turkish schools and analysed using confirmatory factor analysis and structural equation modelling.

The results suggested the direct empirical relationship of principal self-efficacy and openness to change with transformational leadership, and indirect through professional well-being.

Our study enriched our understanding of school leadership by elucidating the potential mechanisms that underpin the implementation of transformational leadership practices.

Reading habit plays a pivotal role in individuals' personal and academic growth, making it essential to encourage among campus users. University libraries serve as valuable platforms to promote reading by providing access to a diverse range of books and resources. Recommending books through personalized systems not only helps campus users discover new materials but also enhances their engagement and satisfaction with the library’s offerings, contributing to a holistic learning experience.

This study presents a web-based solution, the Web-Based Hybrid Intelligent Book Recommender System (W_HybridBook), as a solution that addresses challenges like cold start issues and limited scalability by factoring in user preferences and item similarities in generating book recommendations. The paper improves the traditional hybrid system using Genre-Oriented Profiles (GOPs) instead of original rating profiles of users when determining similarities between individuals. Consumption-based genre profiles (W_HybridBook-CBP) are created by assessing whether an item has received any ratings in the dataset, and vote-based genre profiles (W_HybridBook-VBP) are generated by considering the genre categories based on the magnitude of the user’s rating.

The comparative results indicated that users are quite satisfied with the recommendations generated by W\_HybridBook-VBP profiling, with an average rating of 4.0633 and a precision value of 0.7988. W\_HybridBook-VBP is also the fastest way with respect to the algorithm and recommendation run time.

The proposed W\_HybridBook has been then enhanced by adopting two user profiling strategies to boost the similarity calculation process in the recommendation generation phase. This system provides ranking-based recommendations by mainly integrating well-known collaborative and content-based filtering strategies. A dataset has been collected by considering the preferences of both users and academics at Izmir Bakircay University, which is one of the universities with the highest number of books per student. More importantly, this dataset has been released and become publicly available for future research in the recommender system field.

School principals should create a positive school climate through instructional leadership behaviors and support teacher autonomy to reach their ultimate goals. This study examines the relationship between the instructional leadership behaviors of school principals and teacher autonomy, testing the mediating role of school climate and the moderator role of teacher seniority.

This cross-sectional study tests the relationships between the variables with structural equation modeling. By stratified sampling method, research data from 739 teachers in six central districts of Ankara during the 2022–2023 academic year.

Results showed that school principals' instructional leadership behaviors, teacher autonomy, and perceptions of school climate were above average. The study also indicates that the instructional leadership behaviors of school principals are positive and significant predictors of teacher autonomy and school climate and that school climate is a positively significant predictor of teacher autonomy. Moreover, school climate partially mediates the relationship between instructional leadership and teacher autonomy, and teacher seniority has a moderator role.

This study is limited to the opinions of the teachers working in the official primary, secondary and general high schools in the districts of Ankara in the 2022–2023 academic year on the instructional leadership of the school principals, the teachers' perceptions of autonomy and the school climate. It has been observed that there is a relationship between the instructional leadership behaviors of school principals and teacher autonomy. It can be said that the instructional leadership behaviors of school principals support teachers to exhibit autonomous behaviors in instructional strategies and processes, curriculum, classroom management, professional development and communication.

It is seen that the instructional leadership behaviors of school principals affect teacher autonomy through school climate. It can be said that with the instructional leadership behaviors of school principals, the school climate is more democratic, success-oriented, sincere, supportive of teacher leadership and transforming conflicts into an opportunity for school development, thus affecting teachers' areas of autonomy. We can say that with the development of teachers' autonomy, more effective instructional strategies and instructional processes are developed, the curriculum is transferred with more permanent teaching techniques, professional communication is transformed into collective actions and more comprehensive studies are planned and implemented.

This study will extend the literature by revealing the complex link between instructional leadership, teacher autonomy, school climate and teacher seniority. Furthermore, this study estimates how these complex interactions emerge in non-western cultures with centralized educational structures.

This study aims to analyze the war museum experience by analyzing the comments and feedback provided by visitors on Google and TripAdvisor. This analysis intends to uncover the various aspects of war museum experiences.

A total of 201 comments, in which visitors explicitly articulated their experiences at the museum, were subjected to analysis. The comments were examined using a netnography analysis. Four dimensions; object experience, cognitive experience, introspective experience and social experience were used to group the analyzed remarks.

The findings indicate that the majority of the participants' museum experiences at the Canakkale Gallipoli Epic Promotion Center were introspective experiences, that the visitors felt extremely strong emotions as a result of the technological systems used in the museum and that they perceived the museum as being in a combat zone. Additionally, it was noted that the appearance of the artifacts in the museums really impressed the tourists and that the museum had provided them with thorough information about the war.

The limitations of this study are the number of visitors to the museum and the number of reviews written on Google and TripAdvisor about the visit experience. Especially since the majority of the reviews on Google do not include comments and only consist of ratings, the number of comments on the museum experience is limited.

While there exists a range of studies examining the experiences of tourists at historical places, there is a scarcity of research that specifically focuses on analyzing the impacts of these experiences from the visitors' standpoint. Given the absence of any existing study examining the experiences of war museum visitors using the netnographic approach within this particular context, this research is believed to possess originality and is anticipated to address the existing gap in the relevant literature. Furthermore, this work holds significant theoretical and practical ramifications for curators and scholars. To the best of the authors’ knowledge, since this research is the first to comprehensively analyze the experiences of war museum visitors using the netnographic approach and no similar studies have been found in existing literature, the findings of this study are considered original.

This paper evaluates consumers' responses to claims regarding fruit sustainability. The authors compared the effects of this factor on consumers' moral satisfaction and purchase intention with respect to 12 sustainability claims.

A mixed-model experiment was conducted with seven fruits (i.e. guava, pineapple, red apple, green apple, red grape, green grape and avocado) to evaluate the effects of the 12 sustainability claims on purchase intention through moral satisfaction, relative to a control condition.

The results show that claims of supporting local farmers are those that move consumers the most. Claims regarding local farmers' production positively affect moral satisfaction and purchase intention.

This paper takes a consumer behavior approach to sustainability, enabling organizations to consider consumer behavior outcomes that could affect their strategic investments and commitment to social responsibility.

Food-related studies have not produced consistent results with respect to the relevance that sustainability claims have for consumers. This study differs from previous studies, as it focuses on fruit, a product that is important for social and environmental sustainability issues. This study demonstrates that, in the case of fruit, sustainability arguments are meaningful to young consumers through the mediating effect of moral satisfaction. Thus, the effect of claims is predicted by the meaning these arguments have for the consumer.

Este artículo evalúa las respuestas de los consumidores a los argumentos de sostenibilidad en una fruta. Se comparan los efectos de este factor en la satisfacción moral y la intención de compra de los consumidores con respecto a 12 argumentos de sostenibilidad.

Se realizó un experimento de modelo mixto con siete frutas (guayaba, piña, manzana roja, manzana verde, uva roja, uva verde y aguacate) para evaluar los efectos de los 12 argumentos de sostenibilidad sobre la intención de compra a través de la satisfacción moral, en relación con una condición de control.

Los resultados muestran que las afirmaciones de apoyo a los agricultores locales son las que más influyen en los consumidores. Las afirmaciones relativas a la producción de los agricultores locales afectan positivamente a la satisfacción moral y a la intención de compra.

Este trabajo adopta un enfoque de la sostenibilidad basado en el comportamiento del consumidor, lo que permite a las organizaciones considerar los resultados del comportamiento del consumidor que podrían afectar a sus inversiones estratégicas y a su compromiso con la responsabilidad social.

Los estudios relacionados con la alimentación no han arrojado resultados consistentes respecto a la relevancia que los argumentos de sostenibilidad tienen para los consumidores. Este estudio difiere de los anteriores, ya que se centra en la fruta, un producto importante por cuestiones de sostenibilidad social y medioambiental. Este estudio demuestra que, en el caso de la fruta, los argumentos de sostenibilidad son significativas para los consumidores jóvenes a través del efecto mediador de la satisfacción moral. Así, el efecto de los argumentos se predice por el significado que estos tienen para el consumidor.

This study aims to examine how travellers’ non-immersive virtual heritage authenticity, sense of presence and virtual tour satisfaction stimulate their behavioural intentions (continuance and travel intention) within the stimulus–organism–response model.

A questionnaire was designed to survey Turkish travellers (n = 275) participating in a virtual tour. A structural equation modelling method was used to estimate the model and test the research hypotheses.

Research findings revealed that four out of six hypotheses were supported. Based on the study outputs, authenticity and sense of presence impact overall travellers’ satisfaction. Furthermore, satisfaction influences continuance intention and travel intention.

The study presents a pioneering effort to investigate tourists’ non-immersive virtual heritage tour experiences in a developing destination context through a theoretical framework.

Many countries struggled to respond to the pandemic burden; in fact, most suffer from healthcare incapacity generally. Therefore, they need to find innovative systems to compensate for their deficiencies in dealing with current and future problems. One such goes down the public-private partnership (PPP) route. It is important to note, however, that PPP is not a magic wand, and some of these projects have been criticized for overruns that exceed the value created. Aiming to promote the value created in healthcare PPP projects, this study aims to identify factors and critical points related to their implementation.

A two-stage literature review was conducted to shape semi-structured interviews. Based on this, the questions to be asked in the interviews were prepared. The interviews were conducted with twelve experts. The transcripts of the twelve semi-structured interviews were analyzed using manual thematic analysis to reveal the most critical value-creation factors (VCFs). The VFCs were validated by comparing them with the studies in the literature and by having focus group discussions (FGDs) with the experts. Finally, in an FGD, the experts discussed how these factors affect value creation in healthcare PPP projects.

The findings show that VFCs can be categorized into four dimensions: assets, partnership synergy, cooperation environment and processes. Based on the frequency of codes during the thematic analysis, the most frequently addressed VFCs in each category were identified. These were complementary skills and resources, attitude, early establishment of the operational body and effective design development, respectively.

This research contributes to both society and practice by unveiling VCFs and effective ways to achieve them in healthcare PPP projects. Thus, practitioners can generate more value and bring value to the forefront of healthcare PPPs, which can then enhance the value gained by society.

Studies to date have offered little about VCFs and how to realize value in PPP projects by considering the factors involved in them. Moreover, value creation in PPP healthcare projects has largely remained unexplored, despite PPPs being adopted and investigated quite commonly.
