The purpose of this paper is to determine whether it is useful to tease apart the intimately related propositions of social production and social construction to guide thinking in the multidisciplinary study of disasters.

The authors address our question by reviewing literature on disasters in the social sciences to disambiguate the concepts of social production and social construction.

The authors have found that entertaining the distinction between social production and social construct can inform both thinking and action on disasters by facilitating critical exercises in reframing that facilitate dialog across difference. The authors present a series of arguments on the social production and construction of disaster and advocate putting these constructs in dialog with vulnerability frameworks of the social production of disasters.

This commentary contributes to disambiguating important theoretical and practical concepts in disaster studies. The reframing approach can inform both research and more inclusive disaster management and risk reduction efforts.

This paper aims to explore how the novel information technology (NIT) [1] affects three dimensions of sustainable supply chain performance (economic performance, environmental performance and social performance) and how two dimensions of IT alignment (IT infrastructure alignment and IT human resources alignment) mediate the relationship between them.

NIT is defined, the dimension of IT alignment is expanded, the theoretical hypotheses are proposed and are tested using survey data from 394 manufacturing enterprises using NIT in China.

The results indicate that NIT plays a positive role in improving sustainable supply chain performance, and IT alignment mediates the impact of NIT on sustainable supply chain performance.

This study highlights the impact of NIT on sustainable supply chain performance and demonstrates IT alignment as a mediator between them, it also provides a deeper understanding of how different dimensions of IT alignment affect sustainable supply chain performance

This research investigates the impacts of movie consumers' willingness, measured by the number of people who want to watch a movie, on the relationship between event marketing and box office revenue. This study aims to provide marketers with practical event marketing strategies and tactics to improve box office revenue.

Panel data was collected for 1,141 movies released in China from year 2014–2018 for a total of 12 weeks, spanning 4 weeks before and 8 weeks after release. The mediating effect of consumers' willingness on the relationship between event marketing and box office revenue was tested through a stepwise method and the generalized least squares method based on random effects.

Movie consumers' willingness mediates the effect of event marketing and box office revenue. Both movie consumers' willingness and box office revenue follow an inverted U-shaped distribution against the intensity of event marketing. From the second week before release to the first week after release, intensified event marketing enhances box office revenue. Various types and intensities of event marketing should be employed in different periods of time to increase the total box office revenue.

This research ignores the costs of various types of event marketing for different movies. Future research could consider the cost-effectiveness of event marketing.

The findings of this paper provide meaningful insights on event marketing strategies for practitioners.

This study contributes to the field by verifying movie consumers' willingness as a mediator between event marketing and box office revenue. The study also provides empirical evidences on effective types and reasonable intensities of event marketing over the whole lifecycle of movies.

This study aims to explore the feasibility of adding Si₃N₄ nanoparticles to Sn58Bi and provides a theoretical basis for designing and applying new lead-free solder materials for the electronic packaging industry.

In this paper, Sn58Bi-xSi₃N₄ (x = 0, 0.2, 0.4, 0.6, 0.8, 1.0 Wt.%) was prepared for bonding Cu substrate, and the changes in thermal properties, wettability, microstructure, interfacial intermetallic compound and mechanical properties of the composite solder were systematically studied.

The experiment results demonstrate that including Si₃N₄ nanoparticles does not significantly impact the melting point of Sn58Bi solder, and the undercooling degree of solder only fluctuates slightly. The molten solder spreading area reached a maximum of 96.17 mm², raised by 19.41% relative to those without Si₃N₄, and the wetting angle was the smallest at 0.6 Wt.% of Si₃N₄, with a minimum value of 8.35°. When the Si₃N₄ nanoparticles reach 0.6 Wt.%, the solder joint microstructure is significantly refined. Appropriately adding Si₃N₄ nanoparticles will slightly increase the solder alloy hardness. When the concentration of Si₃N₄ reaches 0.6 Wt.%, the joints shear strength reached 45.30 MPa, representing a 49.85% increase compared to those without additives. A thorough examination indicates that legitimately incorporating Si₃N₄ nanoparticles into Sn58Bi solder can enhance its synthetical performance, and 0.6 Wt.% is the best addition amount in our test setting.

In this paper, Si₃N₄ nanoparticles were incorporated into Sn58Bi solder, and the effects of different contents of Si₃N₄ nanoparticles on Sn58Bi solder were investigated from various aspects.

The investigations could guide the structural design and fatigue life prediction of air-conditioning compressor valve plates.

The High-Cycle Fatigue (HCF) and Very-High-Cycle Fatigue (VHCF) behaviors of stainless steel used for air-conditioning compressor valve plates were investigated. Monotonic and cyclic loading conditions were designed to explore the fatigue responses according to the load characteristics of the structure.

The crack initiation can be observed as the arc-shaped cracks at both sides of specimens and Y-shaped crack bifurcation in the specimens. Moreover, the middle section and the cracks at both ends are not connected to the surface of the specimen. The stress-life results of the materials under two directions (vertical and horizontal) were provided to examine the difference in fatigue strength.

Monotonic and cyclic loading conditions were designed to explore the fatigue responses according to the load characteristics of the structure. Based on the experimental data, the results indicate that specimens under cyclic loading conditions could demonstrate better mechanical performance than static loadings.

The purpose of this paper is to investigate the mediating roles of knowledge sharing behaviors (knowledge collecting and donating) in linking the relationship between high-commitment human resource management (HRM)practices and specific aspects of innovation capability, namely, exploitative and exploratory innovation.

The paper is based on quantitative approach and structural equation modeling to examine the correlation among the latent constructs based on the survey data collected from 281 participants in 95 Chinese firms.

The findings of this study support the mediating role of knowledge sharing (KS) behaviors in the relationship between HRM practices and aspects of innovation capability. It highlights the important role of knowledge donating and indicates that the effect of knowledge donating is more significant than that of knowledge collecting on exploitative and exploratory innovation.

Future research should investigate the impact of high-commitment HRM practices on innovation capability under the moderating effects of organizational variables to bring better understanding on the relationship among them.

The paper significantly contributes to increasing knowledge and insights on the correlation between high-commitment HRM practices and specific forms of innovation. The understanding on mediating role of KS contribute to advancing the body of knowledge of HRM and innovation theory.

Institutional actors are critical allies for grassroots movements, but few studies have examined their effects and variations within the non-democratic context. This chapter argues that while institutional allies are heavily constrained and unlikely to give open endorsement to grassroot activists, some institutional activists indirectly facilitate movement mobilization and favorable outcomes in the process of advancing their own political agendas. Drawing upon in-depth interviews conducted in 2008 and 2012, I illustrate this argument by examining the Anti-PX Movement – a landmark grassroots environmental movement against a chemical plant – in Xiamen, China. I find that the environmental institutional actors were constrained and divided, yet some still fostered opportunities for movement mobilization and in turn exploited the opportunity created by the protesters to pursue their policy interests, thus facilitating positive movement outcomes. As long as the claims are not politically subversive to the authoritarian rule, this type of tacit and tactical interaction between institutional activists within the state and grassroot activists on the street is conducive to promoting progressive policy changes.

Multiple assembly sequences can increase the flexibility of assembly systems and consequently lead to better performance. The relationship between multiple assembly sequences and their impact on the performance of assembly systems are studied. Based on the concept of operation flexibility, this paper presents a flexibility measure to evaluate each operation sequence. A flexibility‐based criterion is proposed to prioritize each operation, which is then used to guide the assembly scheduling. A simulation study demonstrates that when using the criterion, higher system flexibility is achieved and consequently better performance of the assembly systems is obtained.

The purpose of this paper is to examine the prevalence of academic stress and exam anxiety among private secondary school students in India as well as the associations with socio-economic and study-related factors.

Participants were 400 adolescent students (52 percent male) from five private secondary schools in Kolkata who were studying in grades 10 and 12. Participants were selected using a multi-stage sampling technique and were assessed using a study-specific questionnaire.

Findings revealed that 35 and 37 percent reported high or very high levels of academic stress and exam anxiety respectively. All students reported high levels of academic stress, but those who had lower grades reported higher levels of stress than those with higher grades. Students who engaged in extra-curricula activities were more likely to report exam anxiety than those who did not engage in extra-curricula activities.

Private high school students in India report high levels of academic stress and exam anxiety. As such there is a need to develop effective interventions to help these students better manage their stress and anxiety.

This is the first study the authors are aware of that explores the academic stress levels of private secondary school students in India. The study identifies factors that may be associated with the experience of high levels of stress that need to be explored further in future research.

The purpose of this paper is to obtain liquid acrylate oligomers containing carboxyl groups as excellent toughening agents for epoxy resins.

Liquid acrylate oligomers containing carboxyl groups were synthesised by the solution polymerisation of butyl acrylate (BA), acrylic acid (AA) and acrylonitrile (AN) as monomers. The liquid acrylate oligomers were used as the toughening agents for epoxy resins. The chemical structure of the oligomers was characterised by ¹³C nuclear magnetic resonance (NMR) spectroscope. The morphology of modified epoxy networks was analysed by scanning electron microscope (SEM). The mechanical and thermodynamic properties were measured by universal testing machine and dynamic mechanical analyser (DMA).

The results show that AA and oligomer concentrations have great influence on the morphology, mechanical and thermodynamic properties of the modified epoxy networks. When the 10 wt percent oligomer containing BA and AN and AA in the ratio of 75/20/5 is used to modify the epoxy resin, the increase in impact strength of the modified epoxy network is 291.5 percent over the unmodified epoxy network due to addition of the oligomers without a sacrifice in heat‐resistance properties. Fracture surface analysis by SEM indicates the presence of a two‐phase microstructure.

The modified epoxy networks can be used as high performance materials such as adhesives, sealants and matrices of composites.

The liquid acrylate oligomers containing carboxyl and nitrile groups which were synthesised with BA, AA and AN as monomers by the solution polymerisation are novel and can greatly increase the toughness of epoxy resins without loss of thermal resistance.
