Drawing on a sensemaking perspective, this study aims to theoretically and empirically investigate the effects of participative corporate political activity (PCPA) on radical innovation and how regulatory uncertainty and technological uncertainty affect firms’ choice of PCPA as well as its effectiveness on radical innovation.

Hierarchical regression analyses were conducted to test the research model based on survey data collected from 227 Chinese manufacturing firms.

The results indicate that PCPA has a significantly positive effect on radical innovation. Both regulatory and technological uncertainty are positively related to PCPA. In addition, regulatory uncertainty strengthens the positive relationship between PCPA and radical innovation, whereas technological uncertainty weakens this relationship.

This study reveals that firm managers should be mindful that PCPA is beneficial to firms’ radical innovation activities in China. Additionally, although regulatory uncertainty and technological uncertainty can drive firms to engage in PCPA to cope with the ambiguity they experienced, managers should also be alert to the complicated role of environment forces in enlarging or discounting the positive effect of PCPA on radical innovation.

The findings offer fresh insights into the use of PCPA to manage the uncertain external environment when pursuing radical innovation activities in China.

The spot market has been gradually recognized as an important alternative purchasing source. To maintain a flexible replenishment strategy, call, put and bidirectional option contracts, as a risk hedging, are in combined usage with the spot market, respectively. The purpose of this paper is to analyze a finite-horizon replenishment problem with option contracts in the context of a spot market.

Based on stochastic dynamic programming, the firm’s optimal replenishment policy with either call, put or bidirectional option contracts is always shown to be order-up-to type, characterized by an upper threshold and a lower one. The corresponding policy parameters in different cases are calculated through an approximate algorithm. This research highlights the effectiveness of option contracts on the firm’s operational strategies and overall profitability.

This study reveals that the firm is better off with option contracts than without them. When the price parameters are the same for different option contracts, bidirectional option contracts are the best choice among these flexible contracts; otherwise, unilateral option contracts might be either better or worse than bidirectional ones. In addition, if low inventory costs and high spot price volatility are confronted, the firm prefers to call option contracts rather than put ones; otherwise, there exists an opposite conclusion.

In addition to highlight the advantage of option contracts over wholesale price contracts, this paper provides interesting observations with respect to the effect of different option contracts on the firm. Many significant insights derived from this research do not only contribute to the provider’s feasible design of the supply contracts, but also contribute to the user’s rational operational strategies for higher profitability.

This study broadens the understanding of how omnichannel service convenience, shopping value and channel congruence affect customer perceived trust and satisfaction and, in turn, affect selection intention after an omnichannel shopping experience.

Target participants were recruited based on previous purchases from the Japanese clothing brand Uniqlo. A questionnaire was distributed via social media. In total, 341 valid responses were collected for structural equation modelling (SEM).

The results revealed that in omnichannel shopping context, perceived trust and satisfaction are positively affected by service convenience and shopping value and are especially affected by channel congruence. Further analysis showed that perceived trust and satisfaction have a positive effect on omnichannel selection intention, with satisfaction playing a mediating role in the relationships of omnichannel service convenience, shopping value and channel congruence with omnichannel selection intention.

This study contributes to the literature on omnichannel customer behaviour by shedding light on the antecedents of intention to select omnichannel retailers from the customer’s perspective.

This study aims to enhance the assessment of green governance in energy projects along the Belt and Road, reduce the influence of fuzzy judgment, and construct a grey network analysis model from the perspective of Environmental, Social, and Governance (ESG).

The ESG concept is used to establish an evaluation indicator system. The Analytic Network Process (ANP) and the Grey System Theory are applied sequentially to determine the green governance grade of energy projects, exemplified by an evaluation of five projects.

The Karot hydropower project has the best green governance status among the five projects and is of excellent grade. This is followed by the Hongfeng photovoltaic project, the De Aar wind power project, and the Yamal liquefied natural gas project, which are of good grade. The Lamu coal power station project has the worst green governance and is at a medium level.

This study can assist Belt and Road energy projects in identifying their deficiencies and promoting sustainable development by providing a robust framework for green governance evaluation.

The indicator system developed in this study includes social and project governance aspects in addition to environmental performance, reflecting the comprehensive green governance status of projects. The combined use of ANP and grey system theory fully considers the mutual influence relationship between indicators and improves the objectivity of green governance grade judgment.

Due to rapid product obsolescence, there is a significant decline in the market prices, which causes that the sale season is often divided into two periods. This paper aims to consider a class of two-period supply contracts that offer the retailer the ordering flexibility in response to the market changes. This paper analyzes the two-period ordering and coordination problem with option contracts.

The authors incorporate call, put and bidirectional option contracts into the two-period ordering model. By applying stochastic dynamic programming, the authors derive the retailer’s optimal ordering policies for two periods. By benchmarking the case without option contracts, they highlight the advantage of option contracts. Through the mutual comparisons, the authors also explore the impacts of different option contracts. On this basis, the authors explore the conditions on which two-period supply contracts containing options can coordinate the supply chain.

This study shows that the retailer is always better off with option contracts. In addition, the effectiveness of different option contracts depends on the option contract parameters. When the parameters are the same for different option contracts, bidirectional option contracts are superior to call and put ones; otherwise, bidirectional option contracts might be superior or inferior to call and put ones. If designed properly, two-period supply contracts containing options can coordinate the two-period supply chain.

This paper is the first to highlight the value of option contracts as well as explore the role of different option contracts on the two-period procurement problem. The insights derived from our analysis can provide a good way on how to help the retailer work more efficiently in a two-period setting.

This study aims to explore the application of emojis to mood descriptions of fiction. The three goals are investigating whether Cho et al.'s model (2023) is a sound conceptual framework for implementing emojis and mood categories in information systems, mapping 30 mood categories to 115 face emojis and exploring and visualizing the relationships between mood categories based on emojis mapping.

An online survey was distributed to a US public university to recruit adult fiction readers. In total, 64 participants completed the survey.

The results show that the participants distinguished between the three families of fiction mood categories. The three families model is a promising option to improve mood descriptions for fiction. Through mapping emojis to 30 mood categories, the authors identified the most popular emojis for each category, analyzed the relationships between mood categories and examined participants' consensus on mapping.

This study focuses on applying emojis to fiction reading. Emojis were mapped to mood categories by fiction readers. Emoji mapping contributes to the understanding of the relationships between mood categories. Emojis, as graphic mood descriptors, have the potential to complement textual descriptors and enrich mood metadata for fiction.

Readers articulate mood in deeply subjective ways, yet the underlying structure of users' understanding of the media they consume has important implications for retrieval and access. User articulations might at first seem too idiosyncratic, but organizing them meaningfully has considerable potential to provide a better searching experience for all involved. The current study develops mood categories inductively for fiction organization and retrieval in information systems.

The authors developed and distributed an open-ended survey to 76 fiction readers to understand their preferences with regard to the affective elements in fiction. From the fiction reader responses, the research team identified 161 mood terms and used them for further categorization.

The inductive approach resulted in 30 categories, including angry, cozy, dark and nostalgic. Results include three overlapping mood families: Emotion, Tone/Narrative, and Atmosphere/Setting, which in turn relate to structures that connect reader-generated data with conceptual frameworks in previous studies.

The inherent complexity of “mood” should not dissuade researchers from carefully investigating users' preferences in this regard. Adding to the existing efforts of classifying moods conducted by experts, the current study presents mood terms provided by actual end-users when describing different moods in fiction. This study offers a useful roadmap for creating taxonomies for retrieval and description, as well as structures derived from user-provided terms that ultimately have the potential to improve user experience.

This paper aims to investigate how firm-level factor entrepreneurial orientation affects alliance outcomes, and how two sources of uncertainty – competitive intensity and the dependence of an entrepreneurially oriented firm on its partner – moderate the relationship between entrepreneurial orientation and alliance performance.

The hypotheses are tested using survey data from 196 R&D alliances in China.

The results indicate that the relationship between entrepreneurial orientation and alliance performance has an inverted U shape and is negatively moderated by competitive intensity and the entrepreneurial orientation firm’s dependence on its partner.

Entrepreneurial orientation can have positive and negative effects on alliance performance. Particularly in contexts of intense competition or dependence on partners, firms with an entrepreneurial orientation must fully exploit the advantage this brings them, improve their self-control and alliance-coordination capabilities and emphasize the joint effects of technological innovation and market factors on new product development in case of alliance failure.

This study highlights the dual role of entrepreneurial orientation in R&D alliances. By incorporating external and internal sources of uncertainty (competitive intensity and dependence on the partner), it also offers a more comprehensive understanding of how different levels of entrepreneurial orientation affect R&D alliance performance.

This study aims to investigate the effects of incorporating seaweed composite flour on soft roll dough rheological characteristics and quality.

In this study, wheat flour was substituted with seaweed powder obtained from red seaweed (Kappaphycus alvarezii) at varying proportions (100:0; 99:1; 98:2; 97:3; 96:4; 95:5, 94:6, 93:7 and 92:8) and applied in soft roll production. The effects of seaweed composite flour were evaluated in terms of rheological characteristics, proximate composition and physical properties. The sensory characteristics of the soft rolls was evaluated by 40 untrained panellists by using a hedonic scale.

Farinograph analysis of the soft roll doughs showed that the incorporation of seaweed powder promoted an increase in water absorption, development time and mixing tolerance index, whereas it decreased stability time. Analysis of the proximate composition of the soft rolls showed that protein and carbohydrate contents decreased, but moisture, ash and crude fibre contents substantially increased. Dietary fibre increased with the increase in the proportion of seaweed powder added. The specific volume, bulk density and firmness of the soft rolls ranged from 3.01 to 5.48 cm³/g, 0.18 to 0.33 g/cm³ and 1.86 to 20.63 N, respectively. Sensory evaluation results showed that the mean score of sensory attributes decreased as the proportion of seaweed powder added was increased in the formulations. With regard to the overall acceptability, the panellists preferred the soft rolls with the least amount of seaweed powder added. The results of hedonic tests revealed that the panellists' acceptance decreased as higher amounts seaweed powder were added in the formulations.

This study showed that the seaweed powder of K. alvarezii can be utilised as an ingredient to improve the nutrient composition of baked products.
