Mac 系统更新到 Catalina,Safari 的大多数插件都失效了。只能转向比较吃内存的 Chrome。

Tampermonkey 上线 Mac App store 时,还以为可以重启 Safari。但用了一个月后,无论是 常用的 Zotero connector插件还是 Notion 的剪藏插件,都需要重新调取 Chrome,严重影响了使用体验。

Safari 的轻便,架不住其功能的不完善,只能又重新迁移回 Chrome。

苹果将Safari 所有插件都逼到应用商店,真是社会的退步!!

邮箱客户端(2)

邮箱客户端(2)

上午又折腾了一小时的邮箱配置。现在Spark是我的主力邮箱客户端,mac和ipad、iphone可以统一协调,还是省心不少的。但回国之后,mac上收取邮件比较正常,但在移动端,虽然可以收到邮件,但总是无法正常打开。需要挂载V PN,才能保证连接速度和邮件推送。

在网络上调查了一圈,几乎没有一个完美简洁的邮箱客户端可供选择,这是一个月经问题。很多人推荐mail.app,系统自带的app无论是速度还是稳定性都不错。但我仅用它作备选,主要是它的UI比较丑,功能还不够完善。还有一点我无法忍受的是,在邮箱中设置的文件夹无法同步更改,看着非常别扭。虽然不影响使用,但个人难以接受。

最终,还是退回到Spark上,通过设置访问规则,过滤掉我要用的校园IP,随时保持邮箱在墙外在线。

Color-Coding

Color-Coding

It is so important to take notes when review papers or read books. However, most of the efforts to grasp the information included in the works is invalid or inefficient. Highlight techniques such as color coding play an essential role in reading memories. Here, I log some tips to effectively color coding.

  1. Color-code after initial note-taking

  2. Choose the right tools

  3. Be consistent

  4. Limit your color palette

  5. Use color-coding judiciously

Personally, I use RED to note the easiest content, use GREEN to record something you should recall by 3 secs; and YELLOW to reflect the materials you just have one picture in you mind, BLUE to represent the knowledge never heard.

How to Write the Introduction [by David Evans]

How to Write the Introduction [by David Evans]

全球发展中心高级研究员Evans博士分享的摘要写作经验,写的很棒,共享收藏之。原文标题为”How to Write the Introduction of Your Development Economics Paper“).

You win or lose your readers with the introduction of your economics paper. Your title and your abstract should convince people to read your introduction. Research shows that economics papers with more readable introductions get cited more. The introduction is your opportunity to lay out your research question, your empirical strategy, your findings, and why it matters. Succinctly.

Various economists have provided advice on how to write an introduction. Keith Head gives “The Introduction Formula”: (1) the hook: attract the reader’s interest, (2) the question: what your paper does, (3) antecedents: what work you build on, (4) value-added: how you add to the work you build on, and (5) roadmap of the paper.

Claudia Sahm provides related advice: (1) motivation, (2) research question, (3) main contribution, (4) method, (5) findings, (6) robustness check, and (7) roadmap of the paper.

How does this play out practically? I identified the most recent empirical microeconomic development papers from a range of top journals, including the American Economic Review (AER), the Quarterly Journal of Economics (QJE), American Economic Journal: Applied Economics (AEJ: Applied), and others. Then I outlined the introduction of each paper: What do the authors do in paragraph one? What about paragraph two?

Here’s what I learned.

R语言躺在我的学习清单里,已经很久了。近期振兴创建了一个星球TidyFridy,是一个数据分析,软件应用的学习小组,借此正好开启一项“新”技能的学习。

R语言对我而言,既熟悉又陌生。熟悉的是我们在高级计量经济学所使用的软件就是R,而陌生感来自于自己上课时并没有认真学习,所记无多😂。所以,很多当时自认为被绕过去的人和事,总会在某一天倔强地再次出现在你的面前。
