Abstract
Purpose
This study aims to identify the level of sustainability consciousness among preservice teachers in China under the “Double Carbon” goal.
Design/methodology/approach
A sustainability consciousness questionnaire was distributed to 2,795 preservice teachers aged 17–26 years old from first-year undergraduate to third-year postgraduate students through an online questionnaire tool. The mean, standard deviation and correlation of their sustainability knowingness, attitude and behavior were analyzed using SPSS software.
Findings
First, preservice teachers scored high in sustainability knowingness, attitude and behavior. Second, across different household types, disciplines and university levels (double first-class and nondouble first-class), preservice teachers’ sustainability consciousness scores were comparable to each other. Finally, a negative correlation was found between sustainability knowingness and attitude as well as knowingness and behavior. However, the authors observed a positive correlation between sustainability attitude and behavior. Overall, the level of sustainability consciousness among Chinese preservice teachers is high and no significant differences exist between the sustainability consciousness of preservice teachers with different household types, in different disciplines and at different levels of universities. Influenced by the contextual differences of the relevant concepts in the questionnaire, there is a certain degree of structural differences in the preservice teachers’ level of sustainability consciousness across the dimensions.
Originality/value
This study contributes to the literature by investigating the current status of sustainability consciousness level among preservice teachers in China under the “Double Carbon” goal. The findings of this study provide universities and relevant departments with recommendations for education for sustainable development policies.

Abstract
Purpose
Why do some employees choose to prolong their working hours excessively? The current study tested how core self-evaluations (CSEs) might lead to workaholism and how perceived job demands might mediate this relationship.
Design/methodology/approach
Insights from the extant literature underpin the hypotheses on how CSEs would affect the development of workaholism through perceived job demands. A sample of 421 working people in China completed the online surveys, and the mediation model was tested using Mplus 7.0 (Muthén and Muthén, 1998–2012).
Findings
This study found that different components of CSEs influence workaholism in different ways. Specifically, generalized self-efficacy positively predicts workaholism, whereas emotional stability negatively predicts workaholism. Moreover, most aspects of CSEs (generalized self-efficacy, emotional stability and locus of control) influence workaholism via perceived job demands, specifically via perceived workload but not via perceived job insecurity.
Originality/value
The current study is the first to explore how individuals' fundamental evaluations of themselves (i.e. CSEs) relate to workaholism. The results are helpful for the prevention and intervention of workaholism in organizations.

Abstract
Purpose
Consumers often face trade-offs between important product attributes. Previous research suggests that individuals tend to prioritize attribute differences that are easily processed and aligned. This paper aims to examine the contexts in which nonalignable attribute differences can positively impact consumers’ perceptions of products.
Design/methodology/approach
Four lab experiments were conducted to explore how consumer preferences for superior-alignable versus superior-nonalignable products vary based on purchase occasions, with a specific focus on routine and special occasions.
Findings
Consumers tend to prefer superior-nonalignable products on special occasions and superior-alignable products on routine occasions. This is driven by stronger uniqueness motives on special (vs routine) occasions, as consumers associate nonalignable attribute differences more closely with product specialness. The research also explores the moderating roles of consumers’ need for uniqueness (NFU) and psychological ownership. Consumers with higher levels of NFU consistently prefer superior-nonalignable products, regardless of the occasion type. Additionally, when consumers feel psychological ownership of products with superior-alignable attributes, the perceived specialness of these products increases, reducing the influence of occasion type on consumer preferences for attribute alignability.
Originality/value
This research emphasizes the importance of aligning product attribute differences with specific purchase occasions in marketing strategies.

Abstract
Purpose
The purpose of this paper is to provide an effective way to assess landslide risk quantitatively. Quantitative assessment plays an important role in mitigating the landslide risk and developing a landslide risk-based warning system. However, efficient risk assessment on the large deformation failure process of slope with spatially variable soils is a challenging problem.
Design/methodology/approach
Combining the Monte Carlo simulation (MCS) and the higher-order material point method – the B-spline Material Point Method (BSMPM) – the concept of MC-BSMPM to assess the landslide risk quantitatively is proposed in this paper. The overall dynamic evolution of soil slope failure has been simulated by the BSMPM, and the probability density function of the sliding duration, the sliding kinematic energy, the sliding mass and the sliding distance of the landslide are obtained based on the MCS. Through the four risk assessment parameters of the sliding duration, the sliding kinematic energy, the sliding mass and the sliding distance, the landslide risk could be assessed quantitatively.
Findings
It is found that the post-failure behavior of the landslide conforms well to a normal distribution as the soil physical parameter is in a normal distribution. The variation of soil’s shear strength affects the dynamic motion of the landslide greatly.
Originality/value
The result shows that the landslide hazard cannot be estimated comprehensively by the deterministic BSMPM, while the landslide risk could be more clearly understood and quantitatively assessed with more details by the proposed method, which demonstrates that the MC-BSMPM method is an effective way to assess the landslide risk quantitatively.

Abstract
Purpose
This paper presents a new multi‐channel temperature measurement system (MCTMS) with small size, light weight and low power consumption for the microgravity fluid experiment of drop Marangoni migration on SZ‐4 spaceship, a test module of the manned space mission of China.
Design/methodology/approach
The MCTMS, with a commercial‐off‐the‐shelf (COTS) component monolithic thermocouple amplifier with cold junction compensation AD595, is designed to measure temperature gradient field of up to 6 type T thermocouples Cu‐Constantan for microgravity fluid experiment. Through an analog multiplexer, the very small signal amplitude of the six‐channel temperatures can be acquired and amplified by the same monolithic thermocouple amplifier to retain the consistency of the six channels. A fully mission analysis and evaluation on the COTS component was taken into account before it was used in the thermal and radiation environment of space.
Findings
Using the COTS component in space can increase the system performance and considerably reduce the size, weight, power consumption and the overall complexity of the system. The measurement resolution of the MCTMS reaches 0.1°C because of the utilization of the COTS with high performance. In addition, the transfer function of the AD595 was deduced for type T thermocouples.
Originality/value
This paper suggests an easy way of measuring temperature for microgravity fluid experiment on spacecraft. Using a COTS component on spacecraft, also, is a new practical case study, which is more suitable for on‐board implementation. The MCTMS, presented in this work, has run in‐orbit successfully on SZ‐4 spaceship and the experiment result in space is reported.

Abstract
Purpose
This study aims to investigate how a firm’s sustainable competitive advantage is influenced by the combination of entrepreneurial ecological orientation, digital transformation and dynamic capabilities.
Design/methodology/approach
Based on the qualitative comparative analysis method, this study systematically explores the significant key conditions and configuration effects that affect the growth of sustainable competitive advantage. This study uncovers the causal relationship and complex mechanisms underlying the sustainable and unsustainable competitive advantages for new ventures, by examining the grouping effects of the above three factors – entrepreneurial ecological orientation, digital transformation and dynamic capabilities on those advantages.
Findings
A single factor fails to constitute a necessary condition for sustainable competitive advantage. Three types of configurations are beneficial to sustainable competitive advantage, namely, flexible and responsive type, dynamically adjusted type and type of opportunity resource integration, whereas four types of configurations lead to the unsustainable competitive advantage of new ventures, namely, type of organizational rigidity, informal entrepreneurial type, information-blocking type and technology-deficient type.
Originality/value
According to this study, adopting an entrepreneurial ecological orientation is a novel strategic move. This study offers an extensive review of three aspects of entrepreneurial ecological orientation, dynamic capacities and digital transformation and their mutually synergistic cascading effects on the sustainable competitive advantage of new ventures. This study investigates how three dimensions interact to achieve sustainable competitive advantage for firms, ultimately contributing to the study of sustainable competitive advantage strategies from an entrepreneurial ecosystem perspective.

Abstract
Purpose
As one of the United Nations Educational, Scientific and Cultural Organization initiatives, the creative cities network (CCN) declares the cities that are creative in the contexts of music, gastronomy, design, etc., with the aim of promoting cooperation amongst the member cities and maintaining sustainable urban development. This study aims to identify the destination food image of Gaziantep in Turkey, which is a member gastronomy city of the CCN since 2015. Identified destination food image elements were connected to the common targets of the CCN to show how the city may contribute to the network objectives.
Design/methodology/approach
A two-stage research process was used in the study. First, qualitative approach was adopted for the clarification of projected and perceived destination food image elements. Projected image elements were derived from a content analysis performed on a totally 113 official, semi-official and unofficial online documents in Turkish and English. Perceived destination food image elements were identified by face-to-face interviews, conducted on 10 participants. As a result, 18 projected and 20 perceived destination food image elements were obtained. These were then grouped under 4 main and 22 sub-categories. At the second stage, destination food image elements were matched with common targets of the CCN.
Findings
Destination food image elements, obtained by two qualitative studies, are grouped under 4 main and 22 sub-categories as follows: gastronomic identity (with sub-categories of destination’s identity and local culinary culture); diversity of the destination (with sub-categories of attractiveness of the local food, ease of promotion and high brand value); gastronomic attractions (with sub-categories of restaurants and cafes, culinary museums, farmer markets, orchards, gastronomy tours, gastronomy events (e.g. festivals, competitions), culinary education, books on gastronomy, certification systems, organizations, street foods and vendors and handmade or homemade foods); and qualified workforce and stakeholders (with sub-categories of expert chefs and cooks, specialist suppliers, service personnel, locals and local authorities). These are then connected to the common CCN targets (e.g. cuisine, tourism and festivals; extension of the creative value chain; fostering cultural creativity; and sustainability).
Originality/value
This is one of the early research attempts in examining a member gastronomy city’s food image elements and the role that they played in the success of the CCN’s common targets. Moreover, the study contributes to the literature on the identification of (projected and perceived) destination food image by using content analysis.

Abstract
Purpose
The purpose of this paper is to develop a model considering synergy effect for prefabricated construction service combination selection.
Design/methodology/approach
This research defines prefabricated construction service as a service-led construction method that meets the specific requirements of clients. Based on network theory, the multi-dimensional collaborative relationships of the prefabricated construction inter-services are formulated. The synergy effect is quantitatively calculated through the linear weighting of the strengths of collaborative relationships. Further, a weighted synergy network (WSN) is developed, from which a service composition selection model considering the synergy effect is established. Then, a genetic algorithm is employed to implement the model.
Findings
The results showed that (1) when the number of prefabricated construction services is increased, the synergy effect of combination options is enhanced; (2) The finer-grained prefabricated construction services, the stronger the synergy effect of service combination; (3) Clients have heterogeneous preferences for collaborative relationships, and there are differences in the synergy effect of service combination.
Originality/value
The contribution of this research includes proposed a method to quantify the synergy effect from the perspective of collaborative relationships, explored the specific procedure for the prefabricated construction service combination selection under the service-led construction, and provided a reference for promoting the development in construction. Besides, the model proposed could be applied to prefabricated construction service composition selection with diverse research boundaries or client preferences by executing the same procedure.
