We present an operator based factorization formula for the transverseenergy-energy correlator in the back-to-back (dijet) region, and uncover itsremarkable perturbative simplicity and relation to transverse momentumdynamics. This simplicity enables us to achieve next-to-next-to-next-to leadinglogarithmic (N$^3$LL) accuracy for a hadron collider dijet event shape for thefirst time. Our factorization formula applies to color singlet, $W/Z/gamma$ +jet, and dijet production, providing a natural generalization of transversemomentum observables to one- and two-jet final states. This provides alaboratory for precision studies of QCD and transverse momentum dynamics athadron colliders, as well as an opportunity for understanding factorization andits violation in a perturbatively well controlled setting.

我们提出了一种基于算子的因式分解公式，用于计算背对背（dijet）区域的横向能量-能量相关器，并揭示了其显著的微扰简单性以及与横向动量动力学的关系。这种简易性使我们首次实现了强子对撞机二射流事件形状的次对次领先对数（N$^3$LL）精度。我们的因式分解公式适用于彩色单子、$W/Z/gamma$ +jet和二喷流产生，为一喷流和二喷流终态提供了横动量观测值的自然概括。这为在加速器对撞机上进行QCD和横动量动力学的精确研究提供了一个实验室，也为在一个扰动控制良好的环境中理解因式分解及其违反提供了一个机会。

In this paper, we focus on small business enterprises (SBEs) that usually have low market power but can rely on retailers to transact sales and gain the ability to disclose quality information. Moreover, consumer loss aversion (CLA) is pronounced when buying from SBEs that have yet to develop a strong reputation and uncertain quality. We focus on two competing SBEs with heterogeneous quality levels and discuss their quality disclosure strategies— whether selling through a retailer— in the context of CLA. We study the interaction between consumers' prior belief in product quality and CLA and how these factors affect equilibrium outcomes. We show that a situation in which low-quality and high-quality SBEs both choose to disclose will not occur under a neutral consumer attitude, i.e., it happens only when the aversion level is significant. When the aversion level is low, either the low-quality SBE or the high-quality SBE will decide to disclose, and the disclosing party depends on the prior belief. In addition, CLA significantly impacts the monotonicity of both SBEs' and retailers' prices and profits relating to the consumers' prior beliefs.

在本文中，我们关注的是小型企业（SBE），它们通常市场力量较小，但可以依靠零售商进行销售交易，并获得披露质量信息的能力。此外，当消费者从尚未形成良好声誉和质量不确定的小企业购买商品时，消费者的损失厌恶（CLA）会非常明显。我们以两家具有不同质量水平的相互竞争的中小型企业为研究对象，讨论它们的质量信息披露策略--是否通过零售商销售--与消费者损失规避的关系。我们研究了消费者对产品质量的先验信念与合同法之间的相互作用，以及这些因素如何影响均衡结果。我们的研究表明，在消费者态度中立的情况下，低质量和高质量的中小型企业都选择披露信息的情况不会出现，也就是说，只有当厌恶程度很高时，这种情况才会出现。当厌恶程度较低时，无论是低质量金沙国际娱乐网址还是高质量金沙国际娱乐网址都会决定披露信息，而披露信息的一方取决于事先的信念。此外，CLA 还会显著影响中小型企业和零售商与消费者先验信念相关的价格和利润的单调性。

This research discusses the implementation of the 2013 curriculum in Islamic Religious Education (PAI) teaching. The implementation of the 2013 curriculum requires optimal cooperation among teachers, involving teamwork and compact collaboration. In this study, the author explains the concept of curriculum implementation, the requirements of teachers in Islam, the duties and roles of PAI teachers, and the teachers' abilities in implementing the 2013 curriculum. This research also discusses the stages of planning and implementation of teaching in the 2013 curriculum, including introductory activities, core activities, and closing activities. This study is a descriptive research that aims to provide descriptions of situations or events. The author uses a qualitative descriptive approach in this research. The results of this study indicate that the implementation of the 2013 curriculum in PAI teaching requires collaboration among all stakeholders, including teachers, schools/madrasas, and the educational environment. Furthermore, this research emphasizes the importance of the teacher's role in shaping the character and competence of students while considering the diversity of individuals in learning.

The impact of supply chain resilience on customer satisfaction and financial performance: A combination of contingency and configuration approaches 供应链复原力对客户满意度和财务业绩的影响：应急与配置相结合的方法

Supply chain resilience (SCR) refers to a supply chain's (SC's) ability to recover from disruptions timely and effectively. This study uses a combination of contingency and configuration approaches to examine the direct and contingent relationships between SCR dimensions (i.e., internal, supplier, and customer resilience) and performance. It analyzes survey data collected from 206 Chinese manufacturers. The results show that the three SCR dimensions are positively related to customer satisfaction, whereas customer resilience has no direct contribution to financial performance. Internal resilience moderates the relationship between supplier resilience and performance (negative for customer satisfaction and positive for financial performance). A taxonomy for SCR was developed based on internal, supplier, and customer resilience, providing a holistic perspective for examining the performance discrepancies among four different SCR patterns: high external-leaning, high uniform, medium uniform, and low uniform. These findings offer insights for managers in building SCR from the crisis-management process.

供应链恢复力（SCR）是指供应链（SC）及时有效地从中断中恢复的能力。本研究采用权变法和配置法相结合的方法，研究 SCR 维度（即内部、供应商和客户复原力）与绩效之间的直接和权变关系。研究分析了从 206 家中国制造商收集的调查数据。结果表明，三个 SCR 维度与客户满意度呈正相关，而客户复原力对财务绩效没有直接影响。内部复原力调节了供应商复原力与绩效之间的关系（对客户满意度为负，对财务绩效为正）。根据内部复原力、供应商复原力和客户复原力制定了 SCR 分类法，为研究四种不同 SCR 模式的绩效差异提供了一个整体视角，这四种模式是：高外部倾向、高均匀性、中等均匀性和低均匀性。这些发现为管理者从危机管理过程中建立 SCR 提供了启示。
