Peer review is an essential component of the evaluation and dissemination of new scientific knowledge. The peer review process can be viewed as a decision support framework relying on scholarly review systems, where decision-makers (editors) solicit input from experts (reviewers) to make editorial decisions on submitted manuscripts. Unfortunately, the challenges editors face in securing sufficient reviewers are well-documented, leading to prolonged review times and potentially diminished review quality. We explore and validate this trend through a literature review and interviews with scholars. We then employ a design science research methodology to design, develop, and evaluate potential incentive mechanisms to reverse that trend. In addition to proposing formal design principles that such mechanisms should follow, we suggest a concrete blockchain-based token system that enables editors to offer review incentives while enabling reviewers to flexibly utilize these incentives to meet their needs. We also explain how different types of tokens can be connected to practical submission and reward policies that journals may adopt. Our cost analysis, along with a survey-based field study and qualitative interviews with academics, highlight the effectiveness of our solution. Finally, we propose a formal design theory framework that designers of peer review systems can follow to create meaningful incentives to attract reviewers.

同行评议是评价和传播新科学知识的重要组成部分。同行评议过程可以被视为一个依赖学术评议系统的决策支持框架，其中决策者（编辑）征求专家（审稿人）的意见，以对提交的手稿做出编辑决定。不幸的是，编辑在确保足够的审稿人方面面临的挑战是充分记录的，这会导致审稿时间延长，并潜在地降低审稿质量。我们通过文献综述和对学者的访谈来探索和验证这一趋势。然后，我们采用设计科学研究方法来设计、开发和评估潜在的激励机制，以扭转这一趋势。除了提出这些机制应该遵循的正式设计原则外，我们还建议一个具体的基于区块链的令牌系统，使编辑能够提供审查激励，同时使审稿人能够灵活地利用这些激励来满足他们的需求。我们还解释了不同类型的代币如何与期刊可能采用的实际提交和奖励政策相关联。我们的成本分析，以及基于调查的实地研究和与学者的定性访谈，突出了我们解决方案的有效性。最后，我们提出了一个正式的设计理论框架，同行评议系统的设计者可以遵循这个框架来创建有意义的激励机制来吸引评议者。

Artificial intelligence (AI), specifically AI-assisted diagnosis decision support systems (DSSs), have been integrated into doctors' work in substituted or complementary ways. From the perspective of doctors, the impact of AI roles on work outcomes is a double-edged sword that may induce both positive and negative consequences and even create ethical issues related to work. However, little is known on why and how the dual effects take place. To address this knowledge gap, we draw on coping theory and explore the roles of AI-assisted diagnosis DSSs in doctors' work meaningfulness and core work capability through their coping style. We employ a sequential mixed-methods design to develop a theoretical framework and test the research model. Results indicate that perceived complementation and substitution for non-core tasks are positively associated with work specialization (bright side), promoting work meaningfulness and core work capability. By contrast, perceived substitution for core tasks is positively associated with a threat to human distinctiveness (dark side), which harms work meaningfulness and core work capability. Our findings contribute to the emerging literature on AI's impact in the doctors' workplace and provide ethical suggestions for practitioners.

人工智能（AI），特别是人工智能辅助诊断决策支持系统（dss），已经以替代或补充的方式融入到医生的工作中。从医生的角度来看，人工智能角色对工作结果的影响是一把双刃剑，可能会产生积极和消极的后果，甚至会产生与工作相关的伦理问题。然而，人们对这种双重效应发生的原因和方式知之甚少。为了解决这一知识缺口，我们借鉴应对理论，通过应对方式探讨人工智能辅助诊断DSSs在医生工作意义和核心工作能力中的作用。我们采用顺序混合方法设计来建立理论框架并检验研究模型。结果表明，对非核心任务的补充和替代感知与工作专业化（积极面）、工作意义和核心工作能力呈正相关。相反，核心任务的感知替代与对人类独特性（黑暗面）的威胁呈正相关，这损害了工作的意义和核心工作能力。我们的研究结果为人工智能对医生工作场所的影响的新兴文献做出了贡献，并为从业者提供了道德建议。

Livestreaming entertainment (LSE) platforms have become increasingly popular for real-time social interaction. While high-status actors (prevailing streamers) attract large audiences, new streamers often struggle with visibility and earnings. This study examines how social capital transmission from high-status actors affect emerging streamers' live revenue, using Social Capital Theory and Arousal Theories as frameworks. We analyzed data from 52,010 emerging streamers over two weeks on a major LSE platform. The research shows that visits from established streamers significantly increase new streamers' revenue. This positive effect is notably stronger when new streamers have shown good past performance and belong to top guilds and visiting established streamers have strong performance records and actively interact during their visits. Our findings contribute to LSE platform research by highlighting the supportive role of established streamers. These insights can help platforms develop strategies to enhance platform vitality, diversify content, support emerging streamers' growth, and foster a more sustainable streaming ecosystem.

直播娱乐（LSE）平台在实时社交互动方面越来越受欢迎。虽然高地位的演员（流行的流媒体）吸引了大量的观众，但新的流媒体经常在知名度和收入方面挣扎。本研究以社会资本理论和激励理论为框架，探讨了社会资本传播对新兴流媒体直播收入的影响。我们在LSE的一个主要平台上分析了两周内来自52010个新兴流媒体的数据。研究表明，来自老牌主播的访问量显著增加了新主播的收入。当新的主播过去表现良好，并且属于顶级公会，并且访问的老牌主播有良好的表现记录并在访问期间积极互动时，这种积极的影响就会明显增强。我们的研究结果通过强调知名主播的支持作用，为伦敦政治经济学院的平台研究做出了贡献。这些见解可以帮助平台制定战略，增强平台活力，使内容多样化，支持新兴流媒体的发展，并培养一个更可持续的流媒体生态系统。

The increasing proliferation of harmful memes has a serious negative impact on society, rendering the detection of such memes a formidable challenge. Prior research has predominantly concentrated on the modal and semantic attributes of memes while neglecting the significance of cross-modal interactions and detailed semantic information. Although some approaches have incorporated large language models, they often have the problem of harmful avoidance due to ethical constraints. To address these issues, we propose a novel sentiment-aware cross-modal semantic interaction detector, which delves into the profound implications through three principal dimensions: semantic extraction, modal interaction, and sentiment polarity assessment. In the semantic extraction module, Visual Question-Answering is utilized to incorporate detailed knowledge and descriptions. For modal interaction, the positional relationships between meme objects and texts are investigated, and a distance-based attentional multimodal detector is established. In the sentiment polarity module, the sentiment polarity of the text is judged. These components are integrated to form a cohesive joint detection system. Extensive experiments across three benchmark datasets demonstrate SSID significantly outperforms state-of-the-art baselines, enhancing detection accuracy and exhibiting robustness.

有害模因的日益泛滥对社会产生了严重的负面影响，对这些模因的检测是一项艰巨的挑战。以往的研究主要集中在模因的模态和语义属性上，而忽视了模因跨模态交互作用和详细语义信息的重要性。尽管一些方法结合了大型语言模型，但由于伦理约束，它们往往存在有害回避的问题。为了解决这些问题，我们提出了一种新的情感感知跨模态语义交互检测器，该检测器通过三个主要维度：语义提取、模态交互和情感极性评估来深入研究其深远影响。在语义提取模块中，采用可视化问答的方式，将详细的知识和描述融合在一起。对于模态交互，研究模因对象与文本之间的位置关系，建立基于距离的注意多模态检测器。在情感极性模块中，判断文本的情感极性。这些组件被整合成一个有凝聚力的联合检测系统。在三个基准数据集上进行的广泛实验表明，SSID显著优于最先进的基线，提高了检测精度并表现出鲁棒性。

Intelligent credit decision systems are crucial for financial institutions’ risk management, aiming to mitigate credit risk. While deep learning models offer high predictive accuracy, their opacity hinders decision support. Neural Additive Models (NAMs) offer feature-level interpretability but fail to capture complex interactions among credit risk factors. To enhance both accuracy and interpretability, we propose the Sparse-Enhanced Additive Interaction Neural Network (SAINTNet) for explainable credit scoring. SAINTNet advances NAM’s framework with dual-node additive modules and adaptive sparse feature selection, enabling autonomous feature learning. Leveraging entmax sparsity and optimized temperature settings, SAINTNet: (1) maintains interpretability, particularly for credit feature interactions; (2) achieves superior accuracy compared to black-box models. Experiments on four credit datasets demonstrate SAINTNet’s superior performance and systematic interpretability through global feature importance, local decision analysis, and interaction visualization, improving decision audits in high-risk credit scenarios.

智能信贷决策系统是金融机构风险管理的关键，其目的是降低信贷风险。虽然深度学习模型提供了很高的预测准确性，但它们的不透明性阻碍了决策支持。神经加性模型（NAMs）提供特征级的可解释性，但无法捕获信用风险因素之间复杂的相互作用。为了提高准确性和可解释性，我们提出了稀疏增强的加性交互神经网络（SAINTNet）用于可解释的信用评分。SAINTNet通过双节点加性模块和自适应稀疏特征选择改进了NAM框架，实现了自主特征学习。利用entmax稀疏性和优化的温度设置，SAINTNet:(1)保持可解释性，特别是对于信用特征交互；(2)与黑箱模型相比，精度更高。在四个信用数据集上进行的实验表明，SAINTNet通过全局特征重要性、局部决策分析和交互可视化等方法，具有卓越的性能和系统的可解释性，改善了高风险信用场景下的决策审计。

Online review datasets are always imbalanced and contain numerous outliers or noise, making the accurate and efficient identification of helpful reviews a critical challenge in the digital age. To address this issue, the optimal feature set is first obtained from numerous constructed possible features (including ones based on the knowledge adoption model) by a feature selection method, and then a novel fuzzy nonparallel quadratic surface support vector machine (FNQSSVM) model is proposed for identifying helpful online reviews in this study. For well handling the imbalanced data with outliers or noise, a novel fuzzy membership function is first developed based on the K-nearest neighbor method with respect to the cosine distance, and then incorporated with the kernel-free nonlinear and nonparallel separating ideas to propose the FNQSSVM model by directly using two nonparallel quadratic surfaces for nonlinear classification. Computational results on three crawled real-life datasets in different domains show that the proposed FNQSSVM model outperforms the well-known and state-of-the-art classification methods in terms of classification accuracy for identifying helpful online reviews, within competitive computational time. The proposed method can be integrated into the decision support systems to assess the helpfulness of online reviews and facilitate the ranking of helpful reviews. Our findings can provide valuable managerial insights for online platforms, merchants and customers.

在线评论数据集总是不平衡的，并且包含许多异常值或噪声，这使得准确有效地识别有用的评论成为数字时代的关键挑战。为了解决这一问题，首先通过特征选择方法从大量构建的可能特征（包括基于知识采用模型的特征）中获得最优特征集，然后提出一种新的模糊非并行二次曲面支持向量机（FNQSSVM）模型来识别有用的在线评论。为了更好地处理带有异常值或噪声的不平衡数据，首先基于余弦距离的k近邻方法建立了一种新的模糊隶属函数，然后结合无核非线性和非并行分离思想，提出了直接使用两个非并行二次曲面进行非线性分类的FNQSSVM模型。在不同领域的三个抓取的真实数据集上的计算结果表明，在竞争性的计算时间内，所提出的FNQSSVM模型在识别有用的在线评论的分类精度方面优于已知的和最先进的分类方法。该方法可以集成到决策支持系统中，以评估在线评论的有用性，并促进有用评论的排名。我们的研究结果可以为在线平台、商家和客户提供有价值的管理见解。

Investors increasingly use online investment communities to acquire financial market information before making trading decisions to reduce the cost of information acquisition and get more abundant content. Due to limited attention, investors tend to focus their trading only on a subset of assets that align with their personal investment preferences. Thus, the attention behavior of investors in the communities can reflect their focus trends and indicate future stock movements. Unlike previous research that mainly focused on investor common search and viewing behaviors, we constructed stock clusters based on different common attention behaviors data (i.e., common follow behavior by investors and common mention behavior by content contributors) and compared their predictive capabilities on stock returns. After controlling for some deterministic factors, we verified the existence of comovement among stocks within the clusters (i.e., stock habitats) and found that investors' common attention behaviors can better predict stock returns compared to content contributors. To explore the mechanism, we found a possible direction of information flow between different stock habitats and revealed the leading role of content contributors in online investment communities. This study enriches the literature on stock habitats and information diffusion in online investment communities and provides practical decision support on portfolio management for investors. Moreover, online platform managers can also use our conclusions to provide better decision-making assistance for market participants.

投资者越来越多地利用在线投资社区在进行交易决策前获取金融市场信息，以降低信息获取成本，获得更丰富的内容。由于注意力有限，投资者倾向于只关注与他们个人投资偏好相符的资产子集。因此，投资者在社区中的关注行为可以反映其关注趋势，预示未来的股票走势。与以往的研究主要关注投资者的常见搜索和观看行为不同，我们基于不同的常见关注行为数据（即投资者的常见关注行为和内容贡献者的常见提及行为）构建了股票聚类，并比较了它们对股票收益的预测能力。在控制了一些确定性因素后，我们验证了集群内股票（即股票栖息地）之间存在共动，发现投资者的共同关注行为比内容贡献者更能预测股票收益。为了探索这一机制，我们发现了不同股票生境之间信息流动的可能方向，并揭示了在线投资社区中内容贡献者的主导作用。本研究丰富了网上投资社区中股票生境与信息扩散的相关文献，为投资者的投资组合管理提供了实用的决策支持。此外，网络平台管理者也可以利用我们的结论为市场参与者提供更好的决策辅助。

Online medical crowdfunding has emerged as a vital resource for patients seeking public assistance. As a typical gamification design, leaderboards play a crucial role in boosting users' donation. Grounded in motivational affordance and social influence theories, this study investigates how different leaderboard types and rankings influence donation through the underlying mechanism of sense of self-worth. A 2 (leaderboard ranking: high vs. low) × 2 (leaderboard type: public vs. social) between-subject experiment was conducted to validate our research model. The results reveal that high rankings enhance users' donation intentions by boosting their sense of self-worth. This positive effect is more pronounced in public leaderboards than in social ones. Additionally, donation experience weakens the positive effect of sense of self-worth on donation intention. This study contributes to the decision support systems literatures on online crowdfunding and gamification design with practical implications for fundraising strategies.

在线医疗众筹已成为寻求公共援助的患者的重要资源。作为一种典型的游戏化设计，排行榜在促进用户捐赠方面发挥着至关重要的作用。本研究以动机启示理论和社会影响理论为基础，探讨了不同排行榜类型和排名如何通过自我价值感的潜在机制影响捐赠。为了验证我们的研究模型，我们进行了2（排行榜排名：高vs低）× 2（排行榜类型：公共vs社交）受试者间实验。结果显示，高排名通过提升用户的自我价值感来增强他们的捐赠意愿。这种积极影响在公共排行榜中比在社交排行榜中更为明显。此外，捐赠经历削弱了自我价值感对捐赠意愿的正向作用。本研究对网络众筹和游戏化设计的决策支持系统文献有一定的借鉴意义。

With the proliferation of tourism websites, online reviews have become indispensable for offline decision-makers when selecting hotels. Solely relying on personal judgment poses risks amid diverse preferences. Thus, this study aimed to create a hotel recommendation system that integrates online reviews and ratings with offline travel groups. First, the sentiment analysis of online reviews was integrated with ratings using heterogeneous reviewer weights, transforming them into probabilistic linguistic term sets. Second, by predicting reviewers' travel types and clustering them, a method was devised to calculate subgroup weights, considering online group size and offline social trust networks. Third, attribute importance was determined via an online–offline method (attribute importance optimization model) considering the intensity and ordinal information. Subsequently, an adaptive consensus optimization model was developed based on a novel measurement method. This study offers personalized recommendations for offline decision-makers, providing essential guidance for travel agencies and platforms to enhance services and holding significant practical value.

随着旅游网站的激增，在线评论已经成为线下决策者在选择酒店时不可或缺的工具。在多样化的偏好中，仅仅依靠个人判断会带来风险。因此，本研究旨在创建一个酒店推荐系统，将在线评论和评分与线下旅游团体相结合。首先，将在线评论的情感分析与使用异构评论者权重的评级相结合，将其转换为概率语言术语集。其次，通过预测评论者的旅行类型并对其进行聚类，设计了一种考虑在线群体规模和离线社会信任网络的子群体权重计算方法。第三，通过考虑强度和序数信息的线上-线下方法（属性重要性优化模型）确定属性重要性。随后，基于一种新的测量方法，建立了自适应共识优化模型。本研究为线下决策者提供个性化的建议，为旅行社和平台提升服务提供必要的指导，具有重要的实用价值。

Idea screening in collaborative crowdsourcing communities poses significant challenges for firms. These challenges are primarily attributable to issues of prediction accuracy and information overload. The rapid expansion of idea pools generates a vast amount of data, making it difficult to effectively identify valuable ideas for new product development. This study introduces an interpretable framework for machine learning that integrates a novel exploration and exploitation perspective within the value cocreation model to enhance idea screening. The framework incorporates six theoretical dimensions of the exploration and exploitation of value cocreation (EEVC): the exploration and exploitation of digital resources, direct interactions, and ideas and their comments. Our evaluation reveals that the EEVC-based idea-screening system significantly outperforms the traditional 3Cs model in terms of prediction accuracy. SHAP value analysis further reveals that the exploration and exploitation of digital resources are the most influential predictors of idea implementation. The EEVC framework advances open innovation theory by clarifying how value cocreation dynamics influence idea implementation. Practically, it proposes a human–machine collaboration system that enhances expert decision-making for more effective idea selection.
