How do you define ... &quotDaily active usage&quot seems like a really dangerous term to be optimizing. Taken,你是如何定义……过于美化“每日活跃参与度”这个数值似乎是一件危险的事，taken alone, it is, but you didn&#39t let me finish the other metric, which is, we&#39re watching for conversations and conversation chains.确实，如果你单独讨论这个数值的

Let&#39s see what you guys are asking. I mean, this is -- generally, one of the amazing things about Twitter is how you can use it for crowd wisdom,让我们看看你们在问什么。我觉得，这是——总体而言，推特的特点之一在于它能够集中大众智慧，you know, that more knowledge, more questions, more points of view than you can imagine, and sometimes, many

Well, do you, though? Because that&#39s the core question that a lot of people want to know.并且——安德森：你是这么想的吗？这是许多人想问的一个核心问题。Surely, Jack, you&#39re constrained, to a huge extent, by the fact that you&#39re a public company, you&#39ve got investors pressing on you,当然，杰克，你在很大程度上受到约束，因为这是一家上市公司，你会收到投资者的

We&#39re ordering it the right way, but we&#39re also simplifying the rules so that they&#39re human-readable我们以正确的顺序排列信息，但同时我们也在简化规则，使其简单易懂，so that people can actually understand themselves when something is against our terms and when something is not.这样人们就能理解哪些行为违反了条例，哪些没有。And then we&#39re making

Just to back up a bit, we asked ourselves a question: Can we actually measure the health of a conversation, and what does that mean?让我们倒回去一点，我们问了自己一个问题：我们是否能测量对话的质量？而对质量的定义又是什么？And in the same way that you have indicators and we have indicators as humans in terms of are we healthy or not,就像你我作为人类会有显

And that took some work. And as we dived into that, we realized some of the issues with the fundamentals.这花了一点时间。当我们开始关注这方面时，我们意识到一些原则性的问题。We could do a bunch of superficial things to address what you&#39re talking about, but we need the changes to last,为了达成你所说的目的，我们可以采取一系列浅层措施，但我们需要找到可持续的改进措施，and t

Yeah, I mean, I think you&#39re spot on, but that goes back to the incentives. Like,是的，我觉得你讲的正中要害，但这反过来回到了刚才所说的动机问题。one of the choices we made in the early days was we had this number that showed how many people follow you.在早期，我们设计的系统是这样的：系统会显示关注你账号的人数。We decided that number should be big and bold,

What we could do instead is allow you to follow an interest, follow a hashtag, follow a trend, follow a community,我们可以改进的地方在于让你关注一项兴趣爱好，关注一个标签，关注一种趋势，关注一个群体。which gives us the opportunity to show all of the accounts, all the topics, all the moments, all the hashtags通过这种方式，我们可以给你推荐与你兴趣有关的所有账号、所有话题、th

But there&#39s not an amount of people that are scalable, but how many people do you currently have monitoring these accounts, and how do you figure out what&#39s enough?你说从事这项工作的人数永远不够，那么你现在到底雇佣了多少人来监控账号？你怎么知道这些人足够完成任务？They&#39re completely flexible. Sometimes we associate folks with spam. Sometime

and also give our customers a much better and easier approach to handle some of the things that they&#39re seeing.并且为我们的用户打造更好而简便的方法来处理一些问题。So a lot of what we&#39re doing is around technology, but we&#39re also looking at the incentives on the service:所以我们的大部分工作都是围绕科技展开的，但我们同时也在思考这个服务的动机：What does

Well, first and foremost, my personal goal with the service is that I believe fundamentally that public conversation is critical.首先，我对于推特的个人目标来自于我认为公众交流是最关键的。There are existential problems facing the world that are facing the entire world, not any one particular nation-state,世界上有一些问题，不仅仅某个特定国家地区，全世界

And you go, &quotYou know, that is a powerful point, and our ship, frankly, hasn&#39t been built properly for steering as well as it might.&quot然后你回答：“你们知道吗，那是一个巨大的挑战，说实话，我们的船可能不像它看上去的那样可以轻松转向。”And we say, &quotPlease do something.&quot And you go to the bridge, and we&#39re waiting,然后人们说：“请想想办法。”然后

So about midway last year, we decided that we were going to apply a lot more machine learning, a lot more deep learning to the problem,大约在去年年中，我们决定更多采用机器学习与深度学习，and try to be a lot more proactive around where abuse is happening, so that we can take the burden off the victim completely. And we&#39ve

And implicit in all four of these is the understanding that, as they increase, the conversation gets healthier and healthier.而这四个指标背后蕴含意思是指标越高，谈话的质量就越高。So our first step is to see if we can measure these online, which we believe we can. We have the most momentum around receptivity.所以第一步是试验是否能在网上检测这些

I&#39m really glad to hear that that&#39s something that concerns you,我非常高兴听到你谈论你的担心，because I think there&#39s been a lot written about people who feel they&#39ve been abused and harassed on Twitter,因为我觉得有很多人都觉得自己在推特上被侮辱和骚扰，and I think no one more so than women and women of color and black women.并且

What worries you right now? You&#39ve been very open about lots of issues on Twitter.你现在担心什么？一直以来你都敞开探讨推特上的问题。What would be your top worry about where things are right now?对于现在的情况，你最担心的是什么？Right now, the health of the conversation. So, our purpose is to serve the public conversation, and we have see

So we&#39re actually looking for conduct. Conduct being using the service to repeatedly or episodically harass someone,所以我们实际上在研究行为模式。比如说，有人利用这个平台来持续或是间断性地骚扰他人，using hateful imagery that might be associated with the KKK or the American Nazi Party.利用可憎的意象，比如可能与3K党有关的意象，或是与美国纳粹党有关的。Those are all thing

Ted英语演讲：革命性设计：BranFerren:用艺术与技术改变的时代

我有一个独特的方法，能帮助同事渡过困难时刻，告诉他们思考问题的角度，并真正加深和他们之间的关系，这就是&ldquo去月球&rdquo。这是我在前半生的岁月中学会的特殊技巧，只有在拥有大量相互信任的环境中才能实现。我的月球之旅是从四十年前开始的，和尼尔&middot阿姆斯特朗（Ｎeil Ａrmstrong）完成令人难忘的、真正的月球之旅的时间差不多。在加入家族企业之前，我在新英格兰医学研究机构（The New England Institute for Medical Research）负责管理和筹措资金。一天，我在和老板进行绩效评估时听说许多科学家不喜欢我，当时我完全惊呆了。我自然感到非常受打

有一个15岁的孩子，他顽皮，粗鲁，无礼。在学校里，他惹事生非，与同学打架，没有人喜欢他，也很少有人和他在一起玩耍。但有一个人除外，那是一个叫菲拉的女教师。一天放学后，菲拉叫住了孩子，说：&ldquo是这样子的，老师最近遇到了一道难题，你能帮老师找出答案吗？&rdquo有三个候选人，他们分别是：1.有点迷信，有两个情妇，抽烟凶狠，并且嗜酒如命；2.恋床一般到中午才起来，曾经吸过鸦片；3.曾是国家的战斗英雄，不吸烟，偶而喝点啤酒，年轻时从未做过违法的事情。菲拉说：&ldquo假如上帝要在这三个人中选一位在后来能够造福人类的人，那么他老人家会选谁呢？&rdquo孩子想都没多想，就说：&ldquo当然

1、改变形象法心理自卑的孩子，通常具备服饰保守，说话吞吞吐吐，走路畏缩等特点。从改变服饰、说话的音量、走路的姿势入手，便是改变他们的心态，克服自卑心理的一条捷径。据国外最近的实验显示，人在举重的时候如果大声喊叫，就能多使出15%的力量，举起更重的杠铃。实验同时还证实，昂首阔步的举止以及整洁大方的打扮也能提高自己的信心。因此，专家认为，家长对有自卑心理的孩子应特别注意教育他们改变自己的形象：穿整洁大方的服装，讲话爽快，走路昂首阔步等等。2、语言暗示法语言是思想的表露。积极的语言能使人产生积极的情绪，改变消极的心态，因而家长可以有意识地用&ldquo你聪明!&rdquo&ldquo你一定行!&rd

有些年轻父母，觉得孩子难带，头痛不已，甚至陷入焦躁之中。当父母们陷入这种境地时，该怎样做呢？其实，爸爸妈妈们稍作一些改变&mdash&mdash改变自己对孩子的看法，改变与孩子接触的方式，只要你把原来对孩子的成见以及与孩子交流的积习做一些改变，就可以解决问题了。一直以来，总认为自己的孩子不行，日积月累就形成焦躁不安的情绪。事实上，如果反其道而行之，只要父母积极地看待自己的孩子，就会发现原来的焦躁不安自然而然地消失得无影无踪了。另一方面，父母们自己也必须要有所改变。父母不要一味地试图去改变孩子，其实只要父母自己有了变化，孩子的情形也会迅速地发生相应的改变。在和孩子的接触中，父母是不是总是在发出

&ldquo孩子是夸出来的，改变孩子要从改变家长做起。&rdquo这位母亲送给孩子的生日礼物，值得我们借鉴。儿子楷楷盼望已久的10岁生日就要到了，每当他掐着指头算着生日临近的日子时，脸上总洋溢着一种期盼。是啊，难怪他的心情如此迫切，因为我要在他生日这天兑现我的承诺：一些图文并茂的儿童读物、生日蛋糕，还有羽毛球拍&hellip&hellip其实，这些要求本无可厚非，只是他想一股脑同时得到好几份礼物，这在平时，未免太奢侈。在我看来的一些额外要求，往往都会变作一种与学习成绩、在校表现或是某项特长取得荣誉相挂钩的&ldquo筹码&rdquo。就在半个月之前，一次突然的改变，让我萌生了一个想法，我决定在

我们是如此地爱着我们的孩子，以至于我们几乎不能容忍孩子有一点点的瑕疵；我们对我们自己有太多的不满，于是我们对孩子有太多的期待；我们自己就在父母的不认同中长大，所以我们很难真正认同自己；我们的文化和社会环境中弥漫着否定、批评的气息，而肯定、欣赏和赞扬已成为一种稀缺资源&hellip&hellip于是，我们自然地延续着这样的方式，很习惯地用这样的方式去对待我们的孩子。我们希望孩子比我们更好，但我们的行为和语言却在不断地否定孩子、挑剔孩子。这种负面信息不断的重复，只会给孩子的成长造成负面的影响：刚开始，孩子感觉父母不接纳自己；终于有一天，孩子被父母催眠了，自己内心也会认为：&ldquo我不好，我是不

&ldquo我的孩子天性这么胆小，以后长大了怎么办啊？&rdquo&ldquo我的孩子太内向太害羞了，真担心他以后无法适应社会。&rdquo&ldquo我的孩子太吵了，我想送他去学围棋，让他学会定下来。&rdquo&hellip&hellip在采访中，笔者经常会听到年轻的妈妈这样说自己的孩子，对于特别是那些家里有天性内向、胆小，或者是太过调皮、想法独特的父母，总是担心因为孩子性格方面的原因而影响到孩子长大后的人生。为此，他们总是想尽办法去改变他们认为是不好的孩子的这些天性，结果却适得其反。爱说&ldquo我是个笨蛋&rdquo的男孩9岁的小单是个很可爱的孩子，读小学二年级的他学习中等，平时表现
