美国的驻外大使分为两类：一类是外交官出身的"职业大使"，另一类是跟总统关系密切的"政治大使"。 早些年间，"职业大使"的占比要明显高于"政治大使"，后来随着总统大选消耗的人力物力财力越来越多，驻外大使逐渐 成为获胜一方回馈重要助选者的一种酬劳性岗位，于是"政治大使"的比例越来越高。 典型例子如民主党大使专业户卡罗琳·肯尼迪——肯尼迪总统的女儿。 根据美国的人事任命流程，新任大使须经总统提名、参议院听证会批准后才可就任，因此换届往往会出现数个月的空 缺。 这里面门道就来了，新总统先提名哪些大使、后提名哪些大使，可以一定程度上反映其外交侧重方向。 2012年美国大选的激烈关头，卡罗琳·肯尼迪力挺奥巴马，称"奥巴马像我的父亲"，当选后奥巴马立即提名其担任驻日本 大使。 到2020年拜登和特朗普唇枪舌剑的时候，卡罗琳·肯尼迪再度出来助选，称"我在参议院实习时就是拜登的铁粉"，当选后 拜登提名她出任驻澳大利亚大使。 政治是有规矩的，欠人情必须还，当新总统在舞台中央风光无限之时，切记要雨露均沾到每一个选举桩脚，这样才能保 持队伍的战斗力。 按照原先的规矩，每当总统换届，外交官出身的"职业大使"是不需要更换的，新总统撤换的 ...

一位优雅的女士靠在沙发边，侧身翻看着一叠图纸，光线从客厅落地窗斜斜照进来，勾出她额角几缕银白的发。茶几上放着几页潦草的草图，是她先生 ——贝聿铭——昨夜未眠画下的修改稿。 这是1980年代一个普通的清晨，在贝氏家中，这样的场景早已习以为常。 她不是设计师，却参与了无数作品的诞生；她几乎不出现在镜头里，也从未在领奖台上站过一秒，但在贝聿铭之后的漫长岁月里，这位温和又坚定的女 性，是他人生最坚实的构造支柱。 她叫卢爱玲，原名卢淑华，很多人并不熟悉她的名字。 不久前，我访谈了贝聿铭的儿子贝礼中（父亲是贝聿铭，母亲被忽略）。他在访谈中提起自己的母亲："我母亲是一个被遗忘的人，但她对父亲的成功至 关重要。"他把"至关重要"这个词的英文重复了两遍。 在那一瞬间，我意识到，在那段横跨世纪、波澜壮阔的建筑传奇背后，还藏着另一个长期被忽视的名字。 然而，受限于篇幅，卢爱玲的故事在专访中未能展开太多。 于是有了这篇文章。我们试图从她走入公众视野的零星记录中，重新拼起她的人生剪影：出身于广州望族，是卫斯理学院的高材生、哈佛建筑系研究生， 亦是那个在建筑传奇背后默默撑起一片天的"无名英雄"。 无论是在婚姻起点的并肩求学，还是在建筑困 ...

2025年，脑机接口是投资人眼中当之无愧的抢手货。 这不仅因为今年开春以来，政策红利不断释放，给了行业一剂强心针——"脑机接口"被列入未来产业十 大标志性产品；国家医保局专门为脑机接口新技术价格单独立项；湖北省更是在全国率先出台首个脑机 接口医疗服务价格标准。 更重要的是，国内布局了多年的植入式脑机接口的创业公司，今年纷纷迎来了从实验室迈向临床试验的 里程碑——全国多家医院开设了脑机接口临床研究病房，覆盖帕金森、癫痫、抑郁等多种疾病，并计划 于 2025 年下半年启动全植入体微系统的大规模临床实验。各家公司瞄准第一张脑机接口医疗器械许可 证，商业转化迎来新的希望。 "脑机接口"这个名词，乍一听充满未来科技感，几年前，马斯克几乎以一己之力带火了这个名词。2022 年时，马斯克宣称将正式开始将脑机接口的芯片植入人的大脑，让无法行走或者手臂无法活动的人，可 以通过脑机接口技术恢复他们的行动能力。 在医学工作者的眼中，这也算不上是纯粹的"吹牛"。 从事脑神经研究的医学科学家的想法一向很直白：用这个工具，进行脑疾病医学中的脑保护、康复替代 和具体治疗。 2019年前后，国内一批科研人员掀起了一波创业潮，医疗+脑机接口领 ...

Core Viewpoint - The corruption case involving the former CEO of Ele.me highlights significant failures in supply chain management and internal controls, leading to a systemic issue of bribery and misconduct within the company [1][3][4]. Group 1: Corruption Case Details - The Shanghai police reported the arrest of seven suspects in a bribery case involving over 40 million yuan, with the former CEO of Ele.me, Han Liu, being a key figure [1]. - Han Liu and others exploited their authority in logistics and supplier management to gain improper benefits for suppliers, creating a complete chain of interest transfer [2]. - The corruption persisted for nearly two years before being discovered internally in early 2025, when Ele.me reported the findings to the police [4]. Group 2: Systemic Issues and Governance - The concentration of power in the logistics operations of Ele.me, particularly in supplier selection and resource allocation, lacked transparency and effective checks and balances [3]. - The absence of a robust internal monitoring structure allowed suppliers to engage in bribery to secure their positions and gain preferential treatment [3][5]. - The case raises concerns about the effectiveness of Ele.me's anti-corruption systems and the governance structures in place, indicating a need for improvement in compliance and transparency [5][6]. Group 3: Implications for ESG and Corporate Culture - The incident has tarnished the reputation of Alibaba's ESG efforts, which had previously been considered advanced in the industry [6][7]. - Internal corruption undermines employee trust in the company's integrity and can lead to decreased morale and talent attrition, as well as damaging the perception of fairness among suppliers [9]. - The case serves as a warning for internet platform companies regarding the importance of integrating governance responsibilities into operational risk management, particularly in supplier management and decision-making processes [14][15].
