摘要: The COVID-19 pandemic has impacted the economic growth of almost every country, with many industries facing operational difficulties, and the failures of a large number of restaurants, in particular, have extensively tested the resilience of urban economies. The gastronomy business is one of the most decentralized and location-based consumer business in urban, which is highly related to the economic attributes of cities. However, there are few studies on quantitative analysis of urban economic resilience through the opening and closing of restaurants. Understanding and planning for the aftermath of the COVID-19 may not only minimize detrimental effects but also provide insights into the economic recovery policies. This study analyzes the phenomenon of restaurant failures after the pandemic in Shenzhen, China via percolation in multilayer complex networks. We identify the closed restaurants through data mining, and construct the human mobility network through mobile phone location data, aggregating origin and destination points into grids. We then embedded the restaurants’ Points of Interest (POIs) into the grids, creating an additional restaurant network layer. By considering spatial interactions between restaurants, we constructed a geographical proximity network for restaurants in each grid. Finally, Using these multilayered nested networks, we analyzed the pandemic’s impact and the occurrence of critical phenomena related to restaurant closures under lockdown policies through percolation in multilayer complex networks. As a result, this study found that the severity of the pandemic significantly increased the probability of restaurant failures, with cascade and critical phenomena. However, implementing precise lockdown measures can effectively lower the probability of restaurant closures. These results highlight the effectiveness of accurate lockdown policies in striking a balance between epidemic prevention and economic development, contingent upon the correct identification of high-risk areas. This finding suggests that policy makers and public health departments need to balance policy effectiveness with interventions in economic activities in order to increase the resilience of urban economies during the pandemic. © Author(s) 2023.

摘要: As a supplement to the existing public transit system, bike-sharing is considered an effective solution to the first mileand last mileof travel. While many stakeholders believe that multimodal travel between public transit and bike-sharing can improve urban accessibility and sustainability, few studies have assessed the impact of bike-sharing on existing public transportation systems in terms of efficiency and equality. This research uses three months of mobile phone location data and about 140 million bike-sharing trips (origin- destination, OD) data from Shenzhen, China, to analyze first mile and last mile bike-sharing multimodal travel and measure the impact of bike-sharing on the existing public transportation system in terms of efficiency and equality at different scales. The research finds that bike-sharing is less effective in improving the operational efficiency of urban public transport and creates new inequalities at both global and local scales of the urban public transport system. Bike-sharing is only effective in tiny areas of the city and specific modes (subway bike-sharing) and does not benefit groups with low socioeconomic levels and those living in edge areas of the city. Improving the equity and accessibility of public transportation is a key factor towards promoting sustainable urban development, and the analysis of this study on multimodal travel efficiency and inequality of bike-sharing can provide helpful insights for future sustainable urban planning.

题名: 《新莱茵报》政治纲领的两个要点是如何确定和贯彻的
作者: 廖金英
摘要: 本文重点分析《新莱茵报》政治纲领的两个要点的确定和贯彻。恩格斯1884年纪念马克思和《新莱茵报》时提醒马克思主义的新闻工作者:“任何一个工人政党每当背离了这个策略纲领的时候,都因此而受到了惩罚”。这里值得注意的字眼是“策略”。《新莱茵报》能够留下丰厚的马克思主义新闻观遗产,不仅在于其是以唯物史观为指导的,更重要的是,唯物史观就在新闻实践中被展开,“策略纲领”就是症候和产物。作者认为,马克思和恩格斯采取的策略包括:接受运动的实际起点、坚持符合无产阶级利益的德国统一方案、以全欧洲大陆为视野确定报纸纲领、克制而有立场的新闻报道。

作者: 权玺
摘要: “非遗新青年”与生俱来的数字素养,使其成为数字化语境中践行非物质文化遗产保护、传承与发展的青年力量。非遗新生代传承人、非遗所属社区青年、非遗青年爱好者藉由数字化行动者、数字化实践者和数字化倡导者的实践路径而共同集结为“非遗新青年”,以数字增能的方式完成了自我效能、人际扩展和社会观照与非遗数字化保护、传承及发展之间的同频共振。除此之外,大量非遗青年多元利益相关者得以涌现,并在非遗数字化价值共创过程中,从不感兴趣的“旁观者”到随波逐流的“追潮人”再到身体力行的“守护者”直至成长为义不容辞的“责任人”。非遗新青年正在以“和而不同,异而相融”这一全新的路径指南及价值主张切实益助着非遗的适应性赓续和可持续发展。

作者: 陈新民; 周永东
摘要: 文化类电视节目是传播中华优秀传统文化的重要媒介之一,共情叙事则是其在视听传播艺术方面的创新性表达。文章以《典籍里的中国》为例,从共情传播的角度探讨此类节目的情境建构机制以及多维度的共情叙事方式。研究得出:该节目以影视化的表达方式和戏剧性的结构设计将史书典籍中的文字进行可视化呈现,不仅为观众提供了多维度的视听体验和故事化的情境建构,还激发了观众在心理层面对史书典籍的情感共鸣与文化认同。

作者: 樊亚平
摘要: 从进入新闻职业领域一直到1948年前,徐铸成一直恪守“独身主义”和“超然于党派”之原则。1948年初,他却突然放弃其恪守的原则,开始了“左转”和走向中国共产党的步伐。从表面看,这一转变似乎出于时局变化下的不得已,若仔细分析,就会发现,徐铸成“左转”实为具有历史必然性的选择;其“左转”表面看有点突然,但若放在其新闻生涯的整个过程来考察,放在其对国民党和共产党的认识与态度的历史演变过程来看,其实并不突然,而是有一个认识和态度逐渐转变的过程。具体来说,徐铸成对国民党的认识与态度经历了从赞扬、拥护到不满、批评,再到失望、绝望的转变过程;对共产党的认识与态度经历了从敌视、误会到逐渐了解、有一定程度的好感,再到认识逐渐加深,并产生一定程度的心理、情感接受的转变过程。在这个过程中,徐铸成曾倡导和支持“第三条道路”,但随着“第三条道路”的破产,他最终认识到,走向中国共产党、接受中国共产党的帮助和领导,既是他自己的唯一出路,也是中华民族的唯一出路。正是在这种情况下,他毅然选择“左转”、走向中国共产党。

作者: 张华; 陈莉红
摘要: “媒体主线”思路重在“媒体+”层面建设县级融媒体中心,难以在平台媒体崛起的现实中将其建设成为“治国理政的新平台”。平台媒体的崛起改变了媒体形态、传播形态和社会形态,也深刻影响着社会治理的理念和方式。平台化治理的逻辑要求县级融媒体建设路径“去媒体化”,即在重新定义并调整其政治属性、媒体属性和社会属性及“三重属性”间的关系结构的基础上,通过创新协商民主机制、提供用户数据服务、探索平台化治理机制等“再路径化”策略,实现其功能目标。

作者: 官璐; 何康; 斗维红
摘要: 美国人工智能研究公司OpenAI近期加速迭代,推出了基于GPT-4的“自定义GPT”,用户可以更加简便地创建出自己的专属微调大模型。国内外大模型团队也陆续涌入微调大模型技术下的个性化智能应用赛道,标志着个性化智能信息交互时代即将开启。本文认为,个性化微调大模型下的人机信息交互模式,将是人与机器双向互动优化信息觅食策略的过程。在对话与交谈中,个体不断精确化自己的信息需求表达,同时大模型通过学习用户输入的提示词,不断深化对用户信息需求的理解,提供更加精准的个性化回应。未来微调大模型还有可能作为“人脑的延伸”,辅助人们应对信息过载情景下的信息处理与信息存储任务。

作者: 张利洁; 郝乔丽
摘要: 近年来,我国图书版权"走出去"呈现繁荣景象:版权输出数量不断增长,版权贸易逆差逐渐缩小。然而,数量增长背后却有隐忧:"走出去"没有植根于市场化运作,而是依赖重大工程资助;"走出去"没有形成常态化模式,有应景之嫌;影响力低下,陷入数量崇拜的怪圈;结构失衡等。当前需要从政府和出版社两方入手寻求解决途径,厘清二者在"走出去"过程中扮演的角色,通过市场化运作,实现资源优化配置,取得长远发展,最大限度地提高文化影响力。
