Absent Presence: Li Yu’s Drama Wanli yuan and Early Qing Sartorial Politics

Li Yu’s 李玉 Wanli yuan 萬里圓 (Thousand-li Reunion) is one of the few dramas in the early Qing period that directly addresses the topic of the Ming-Qing transition. Although Wanli yuan was never published in its entirety during the Qing Dynasty, its popular scenes circulated widely on stage, resulting in a series of “performance editions.” Oriented toward stage performance, most of Li Yu’s plays include detailed costume instruction. By contrast, almost none of the extant editions of Wanli yuan includes any costume instruction. Despite this absence, the dialogues and stage directions of the extant performance editions show that different scenes of the drama confront the issue of clothing in sharply different ways. Scenes with an ethical theme adopt Han clothing, whereas scenes of an ethnic theme smuggle in Manchu hairstyle and clothing, suggesting the use of the queue and magua 馬褂 (horse jacket). These two types of scenes circulated through different channels and for different audiences in early Qing society. Through a case study of Wanli yuan, this paper reveals how early Qing dramas interacted with/against the Manchu government’s sartorial regulations, in particular how varying contexts of performance facilitated these sartorial negotiations

Left-continuity of t-norms on the n-dimensional Euclidean cube

AbstractLeft-continuity of t-norms on the unit interval [0,1] is equivalent to the property of sup-preserving, but this equivalence does not hold for t-norms on the n-dimensional Euclidean cube [0,1]n for n≥2. Based on the concept of direct poset we prove that a t-norm on [0,1]n is left-continuous if and only if it preserves direct sups

Sales segmentation for a mobile phone service through logistic regression algorithm

The research aims to describe the CRISP-DM method to identify optimal customer groups that are likely to migrate from a prepaid to postpaid plan in order to formulate an improvement plan in call management by sorting the database. The logistic regression model was applied to analyze the characteristics generated by the purchase of different services. In this sense, groups differentiated by their probability of sales success (migrating from a prepaid to postpaid plan) were found, as segments that reflect needs and characteristics that allow to design marketing actions focused on the objective of increasing the effectiveness, contactability, and sales
