Complex cost structures and multiple conflicting objectives make selecting an appropriate cloud service difficult. The purpose of this study is to propose a novel group consensus decision making method for cloud services selection with knowledge deficit by trust functions.

This article proposes a knowledge deficit-based multi-criteria group decision-making (MCGDM) method for cloud-service selection based on trust functions. Firstly, the concept of trust functions and a ranking method is developed to express the decision-making opinions. Secondly, a novel 3D normalized trust degree (NTD) is defined to measure the consensus levels. Thirdly, a knowledge deficit-based interactive consensus model is proposed for the inconsistent experts to modify their decision opinions. Finally, a real case study has been carried out to illustrate the framework and compare it with other methods.

The proposed method is practical and effective which is verified by the real case study. Knowledge deficit is an important concept in cloud service selection which is verified by the comparison of the proposed recommended mechanism based on KDD with the conventional recommended mechanism based on average value. A 3D NTD which considers three values (trust, not trust and knowledge deficit) is defined to measure the consensus levels. A knowledge deficit-based interactive consensus model is proposed to help decision-makers reach group consensus. The proposed group consensus model enables the inconsistent decision-makers to accept the revised opinions of those with less knowledge deficit, rather than accepting the recommended opinions averagely.

The proposed a knowledge deficit-based MCGDM cloud service selection method considers group consensus in cloud service selection. The concept of knowledge deficit is considered in modeling the group consensus measuring and reaching method.

Contractor selection is critical in green buildings (GBs) since the preferred contractor has the responsibility to achieve construction sustainability as well as relationship sustainability. The developer satisfaction reflecting requirements can boost the cooperative relationship among stakeholders and act as an evaluation scale for the success of GB projects, which needs to be emphasized in the selection process but little involved in the existing research. This study explores improving GB contractor (GBC) selection by integrating developer satisfaction into selection procedures.

A systematic framework of GBC selection including twenty-five criteria from literature review and experts survey is firstly constructed. Both tactical and strategic criteria are further classified into Kano categories (must-be, one-dimensional, and attractive categories) using the fuzzy Kano model (FKM), and weighted by the developer satisfaction index. The model proposed by this study combining FKM and TOPSIS divides the selection process into the filtration phase and selection phase by Kano categories. The proposed model is finally verified through performance comparison among multiple methods in a case.

Selection criteria are measured linearly and nonlinearly, showing criteria having nonlinear satisfaction change accounts for two-thirds of all. Criteria at tactical level tend to be must-be or one-dimensional categories for the developer, and most strategic criteria are classed as the attractive category, indicating that adding strategic criteria is necessary for long-term cooperation. The proposed model, using developer satisfaction to improve the selection process, ensures the selected GBC to be the most satisfactory with requirements of the developer and makes the performance of GBCs easily distinguishable.

This study contributes to the existing body of knowledge for promoting relationship sustainability by supplementing an integrated model with emphasis on developer satisfaction in GBC selection, so as to establish a good initial foundation due to the match between performances of GBCs and needs of developers. It not only helps maximize developer satisfaction in GBC selection by applying satisfaction to pre-construction management, but also instructs GBCs to prioritize performance improvements. The framework is also conducive for developers to classify selection criteria and select other participants (like green suppliers) from the satisfaction perspective in GBs.

This study aims to investigate the supplier selection criteria, relationship quality and level of collaboration in Asian food businesses, while also examining the link between these practices and business performance. The research focusses on food manufacturing and exporting companies in two emerging economies, China and Vietnam.

Food manufacturing and exporting companies in two emerging economies – China and Vietnam were surveyed and analysed to extract factors that reflect supplier management and business performance along with their relationship by factor analysis and hierarchical regression. Then, a two-step cluster analysis was applied to identify clusters based on supplier management and explore how different business performance groups manage their suppliers.

Four clusters that are distinct sets of food firms with detailed references about their typical characteristics revealing their business performance and supplier management practices. Also, the study confirms that certificates, reliability and inspection results constitute the factor of quality-related criteria for food firms. It is an interesting insight into what firms prioritise in selecting and maintaining collaboration and relationships with suppliers that reflect actual demanding specifications for supplier conformity.

The study reveals the business status of the studied companies and each group's specific references, such as the criteria they prefer to select suppliers, the relationship quality and the level of collaboration.

The study is a useful reference for both researchers and practitioners to have a comprehensive view of supplier management in the food industry based on the viewpoint of Asian food manufacturers.

Transnational migration is a key challenge in migrant-sending and host-receiving countries. However, relatively little is known about how migrants use network capital to foster small and medium-sized enterprises (SMEs) in the ASEAN Economic Community (AEC). Therefore, the purpose of this study is to explore how network capital fosters Laotian migrant workers in Thai family SMEs.

This research was conducted using qualitative network analysis (QNA). Referral snowball sampling was used to draw 20 participants from December 2021 to March 2022. Data analysis was performed using Gephi, a software package developed for QNA (coding, network features, measure nodes and network metrics).

The main findings are the following four emerging themes: chain networks, social networks, human networks and financial networks are associated with network capital for fostering Laotian migrant workers in Thai family SMEs.

To the best of the authors’ knowledge, this study is the first QNA to explore how Laotian migrant workers use network capital in Thai family SMEs.

For ranking aggregation in crowdsourcing task, the key issue is how to select the optimal working group with a given number of workers to optimize the performance of their aggregation. Performance prediction for ranking aggregation can solve this issue effectively. However, the performance prediction effect for ranking aggregation varies greatly due to the different influencing factors selected. Although questions on why and how data fusion methods perform well have been thoroughly discussed in the past, there is a lack of insight about how to select influencing factors to predict the performance and how much can be improved of.

In this paper, performance prediction of multivariable linear regression based on the optimal influencing factors for ranking aggregation in crowdsourcing task is studied. An influencing factor optimization selection method based on stepwise regression (IFOS-SR) is proposed to screen the optimal influencing factors. A working group selection model based on the optimal influencing factors is built to select the optimal working group with a given number of workers.

The proposed approach can identify the optimal influencing factors of ranking aggregation, predict the aggregation performance more accurately than the state-of-the-art methods and select the optimal working group with a given number of workers.

To find out under which condition data fusion method may lead to performance improvement for ranking aggregation in crowdsourcing task, the optimal influencing factors are identified by the IFOS-SR method. This paper presents an analysis of the behavior of the linear combination method and the CombSUM method based on the optimal influencing factors, and optimizes the task assignment with a given number of workers by the optimal working group selection method.

This paper aims to introduce a novel structure for the physical internet (PI)–enabled sustainable supplier selection and inventory management problem under uncertain environments.

To address hybrid uncertainty both in the objective function and constraints, a novel interactive hybrid multi-objective optimization solution approach combining Me-based fuzzy possibilistic programming and interval programming approaches is tailored.

Various numerical experiments are introduced to validate the feasibility of the established model and the proposed solution method.

Due to its interconnectedness, the PI has the opportunity to support firms in addressing sustainability challenges and reducing initial impact. The sustainable supplier selection and inventory management have become critical operational challenges in PI-enabled supply chain problems. This is the first attempt on this issue, which uses the presented novel interactive possibilistic programming method.

The purpose of the current application paper is to integrate previous literature with recent results from practitioners on effective practices for utilizing small groups in the leadership classroom.

We use these integrated findings to innovate practice on maximizing the role of undergraduate teaching assistants (UTAs) by matching their tasks to signature pedagogies in leadership education.

The integrated findings revealed three practice themes: (1) match UTAs to pedagogical approach, (2) create small groups by design and (3) providing training and reflection practice for UTAs.

In sum, leadership education can and should challenge historical practices in higher education whereby UTAs are used purely for grading and course logistics management.

Gastronomy can be a key destination choice factor. As tourists, people will be able to learn more about the culture of the place through its culinary assets. This paper aims to analyse the interest and the gastronomic motivations of tourists to the city of Granada (Spain), where two important UNESCO World Heritage Sites (WHS) are included.

To achieve the aim of this study, fieldwork was carried out on a representative sample of tourists in Granada (Spain). Specifically, a total of 1,612 valid surveys were filled out in culinary establishments and historical sites. In these surveys, the opinion of tourists regarding gastronomy and their motivations when travelling was assessed.

The results of this research allow to make a segmentation of tourists into three groups according to their position and their interest in gastronomy based on their destination choice, distinguishing among survivors, enjoyers and experiencers’ tourists. Additionally, it is confirmed that gastronomy is shaped as a motivation that influences the level of tourist satisfaction, performing as a differentiating element that can help increase the competitiveness of the destination.

This research contributes to the scarce academic literature on tourism experiences in a city with WHS recognitions. This study confirms the existence of a relationship between gastronomic motivations and the level of satisfaction achieved by tourists who visit the city of Granada, where no similar studies were found. In addition, this work confirms the connection between gastronomy and culture.

From book challenges to anti–critical race theory and anti-lesbian, gay, bisexual, transgender, queer and questioning legislation, US English teachers have been on the receiving end of a considerable amount of far-right conservative pushback. This study aims to explore the effects of conservative pushback on individual English teachers and their classroom practice. What pushbacks have individual English teachers faced? How has pushback impacted their teaching? What strategies have they developed for navigating pushback?

This qualitative study explores secondary English teachers’ reported experiences with conservative backlash as reported in 15 semi-structured interviews conducted between May 2022 and August 2023.

Participants reported feeling the pressure of increased levels of pushback, and many reported censoring their book selections to avoid additional public scrutiny. At the same time, they also described a range of strategies they have developed for protecting themselves and their practice, such as codifying curriculum, increasing transparency, formalizing review processes for challenging books and strengthening their resolve to resist.

This study offers a timely window on a pressing problem affecting the daily practice of English teachers in the USA.

The use of mindfulness interventions (MIs) as means to manage unwanted or undesirable affect and behaviour has increased in popularity recently. This has resulted in the trial of MIs as a means to benefit well-being within prisons, with some intention of reducing recidivism. This study aims to examine current research regarding the use of MIs within prisons.

A total of 14 studies were manually selected for review inclusion according to their determined eligibility. All studies were required to have taken place in a prison and to include an explicit mindfulness intervention, including mindfulness theory and practice.

Most interventions reviewed demonstrated success, particularly when tailored to the unique needs of a prison environment. Positive changes reported included improvements in participant mental health symptoms, as well as reduced stress and increased mindfulness skills. Some preliminary evidence was provided to indicate the potential longevity of some of these benefits. This review further highlighted some significant questions regarding the generalisability of the proposed suitability of MIs within prison environments including practical delivery constraints and the lack of acknowledgment of the unique challenges and circumstances faced by prisoners.

The findings of this review show positive potential for the use of MIs within prison populations, where these are well-linked to mindfulness theory and to the needs of inmates. The review also suggest that MIs should be investigated thoroughly, examining potential negative implications alongside positive changes. There needs to be further review of the role of MIs within prison populations to ensure their suitability in the custodial environment.

MIs are somewhat inflated in terms of predicted outcomes and sometimes applied to potentially unsuitable groups. A significant gap within the literature also persists regarding potentially negative implications associated with MIs, particularly within unique prison populations. Prison treatment programmes should be developed with careful consideration of unique prisoner needs in comparison to a general population.
