+\chapter{Elegant\LaTeX{} 系列模板介绍}
 
-只有当自己想去做一件事的时候才能把事情做好！
+值此版本发行之际，我们 Elegant\LaTeX{} 项目组向大家重新介绍一下我们的工作，我们致力于打造一系列美观、优雅、简便的模板方便用户使用。Elegant\LaTeX{} 系列模板目前由 ElegantNote，ElegantBook，ElegantPaper，ElegantBeamer 组成，分别用于排版笔记，书籍，工作论文和幻灯片讲稿。这些子项目的名词是一体的，请在使用这些名词的时候不要将其断开（如 Elegant Note 是不正确的写法）。并且，Elegant\LaTeX{}  Book 指的即是 ElegantBook。
+
+请用户在作者的主页下载最新版本，下载地址：\href{https://ddswhu.me/resource/}{https://ddswhu.me/resource/}。本文将介绍本模板的一些设置内容以及基本使用方法。如果您在使用此模板，欢迎把您使用此模板制作的成品发一份给我们，谢谢！如果您有其他问题，建议或者意见，欢迎联系我：\mailto{ddswhu@outlook.com}。
 
 
-\section{ElegantNote 的前世今生}
+\section{ElegantBook 更新说明}
+在这几年间，我们收到了很多用户的反馈，主要的问题涉及到字体安装，编码支持，定理浮动，定理跨页，交叉引用等等。我们思前想后，原先让用户安装字体以追求视觉上的美观并不完美，用户陷入了巨大的麻烦，这违背了我们的模板初衷。因此我们在新版中删除了这部分，用户无需安装任何字体。让我们来看下此次 ElegantBook 模板 3.0 更新的主要内容有：
 
-写 ElegantNote 模板的初衷是为了简化我在写笔记中的工作，因为我不会写类文件和包文件，所以，最当初是想拜托小L做出一个华丽，清爽的 \LaTeX{} 模板，最好是类文件，而且因为这样可以简化导言区复杂的内容。后来，和小L一拍即合，遂开始一起做Elegant\LaTeX{}的设计。
-
-在学校的时候，搞定了定理环境样式的代码。因为不想重复 China\TeX{} 那个经典的页眉页脚，我找到了计量书上的一个图案，小L拿 Ti\emph{k}Z 一点一点把那个画出来了，不过我最后还是用的截取的方式得到的图案。慢慢地，我们把初步的样子做出来了。

-2013年的暑假开始后，我对那个初步的模板做了一点改动，然后用它写了Dynamic Programing 的笔记，并且，在写的过程中，对模板加了封面，也就是模板现在的封面（logo 在Version 2.00中已经改了）。至此，模板的大致样子终于出来了，不过当时也在写笔记的过程中知道了某些不足，比如
-\begin{enumerate}
-\item 定理类的环境在我们这个模板中不能浮动，也不能跨页，在Version 2.00 版本中已经添加。
-\item 某些环境不足，比如例子、假设、性质、结论等环境，在1.00版本中已经增加了这几个环境，在2.00版本中，环境设置更加全面。
-\item 一些我们不可预知的错误将会不期而遇。
-\item 一些我们目前没有需求，但是可以继续改进的地方，比如表格样式，比如抄录样式等。
+\begin{enumerate}[noitemsep]
+   \item 删除了自定义字体设置，改用 \texttt{ctex} 宏包用以支持中文。
+   \item 使用 \texttt{tcolorbox} 宏包改写了原先的定理类环境，目前定理环境等均可以跨页。
+   \item 重新命名了定理类环境的名称（theorem，definition，proposition 等）。
+   \item 重新命名了颜色的名字（first，second，third）。
 \end{enumerate}
 
-写完那个笔记之后越发让我对 Elegant\LaTeX{} 模板的制作更有激情，在和小L相互讨论的几天里，我们终于得到了1.00 版本的 ElegantNote 模板。

-在实际应用中，我们发现了一个比较重要的问题，因为在一般的笔记中，定义、定理经常一起出现，和课本区别比较大的是，通常是一堆定义之后，出现一堆性质或者定理。如果出现这种情况，使用 ElegantNote 模板会导致分块很严重，影响排版质量和美观。思前想后，我们决定将 ElegantNote 模板更新为 ElegantBook 模板，并在未来重新设计一个简洁版本的 ElegantNote。 至此ElegantBook 才横空出世，由于更名原因，ElegantBook 1.00 版本也即原来的 ElegantNote， 而ElegantBook 2.00 为目前的正式版本。
+\begin{enumerate}[noitemsep]
+   \item 设计一个适合的 LOGO；

+   \item 重新设计一个好看的封面。
+   \item 将基础模板改为英文模板，添加选项使其支持中文。

+
+Economics focuses on the behaviour and interactions of economic agents and how economies work. Microeconomics analyzes basic elements in the economy, including individual agents and markets, their interactions, and the outcomes of interactions. Individual agents may include, for example, households, firms, buyers, and sellers. Macroeconomics analyzes the entire economy (meaning aggregated production, consumption, savings, and investment) and issues affecting it, including unemployment of resources (labour, capital, and land), inflation, economic growth, and the public policies that address these issues (monetary, fiscal, and other policies). See glossary of economics.

+The discipline was renamed in the late 19th century, primarily due to Alfred Marshall, from "political economy" to "economics" as a shorter term for "economic science". At that time, it became more open to rigorous thinking and made increased use of mathematics, which helped support efforts to have it accepted as a science and as a separate discipline outside of political science and other social sciences.

+Some subsequent comments criticized the definition as overly broad in failing to limit its subject matter to analysis of markets. From the 1960s, however, such comments abated as the economic theory of maximizing behaviour and rational-choice modelling expanded the domain of the subject to areas previously treated in other fields. There are other criticisms as well, such as in scarcity not accounting for the macroeconomics of high unemployment.

Peer-to-peer (P2P) lending, as a novel economic lending model, has triggered new challenges on making effective investment decisions. In a P2P lending platform, one lender can invest N loans and a loan may be accepted by M investors, thus forming a bipartite graph. Basing on the bipartite graph model, we built an iteration computation model to evaluate the unknown loans. To validate the proposed model, we perform extensive experiments on real-world data from the largest American P2P lending marketplace - Prosper. By comparing our experimental results with those obtained by Bayes and Logistic Regression, we show that our computation model can help borrowers select good loans and help lenders make good investment decisions. Experimental results also show that the Logistic classification model is a good complement to our iterative computation model, which motivates us to integrate the two classification models. The experimental results of the hybrid classification model demonstrate that the logistic classification model and our iteration computation model are complementary to each other. We conclude that the hybrid model (i.e., the integration of iterative computation model and Logistic classification model) is more efficient and stable than the individual model alone.},

+abstract = {Would consumer surplus increase if annuity rates were age-neutral? This paper characterizes the socially optimal contractibility of a given signal in markets with adverse selection. A signal (e.g., age) partitions consumers into subsets (e.g., young and old). A regulator restricts price-discrimination on the basis of the signal if the consumer subsets where the level of cost is higher are also the subsets where there is greater deadweight loss due to adverse selection. Such signals are empirically common. To illustrate the welfare benefit of price discrimination policy, I use a structural model to estimate its impact on the UK annuities market. The model is estimated using proprietary data that include the annuity seller's estimate of each individual's longevity. I find that restricting price discrimination can increase consumer surplus by the equivalent of about {\pounds}6.5 million per year.},

+abstract = {We use data from a major peer-to-peer lending marketplace in China to study whether female and male investors evaluate loan performance differently. Controlling for variables of investor demographics, investor experience, and loan characteristics, we find that loans invested by female investors are more likely to default and have lower loan return in the future than loans invested by male investors. We define abnormal default or abnormal loan return as the part of the loan default or the part of loan return that is not explained by loan characteristics and find that the loans invested by female investors have higher abnormal default and lower abnormal loan return than the loans invested by male investors. Furthermore, female investors perform similarly to male investors in abnormal default or abnormal loan return when investors have high levels of education or income or when investors work in finance or information technology industries.},

+abstract = {The objective of our paper is to explore the role of P2P lending platforms through the prism of the theory of financial intermediation. P2P lending platforms perform the brokerage function of financial intermediaries by matching lenders' supply and borrowers' demand of funding, according to the risk and the maturity of their needs. Unlike banks, P2P lending platforms do not create money and do not perform risk and maturity transformation. However, they can organize secondary markets to trade loan contracts before maturity and some P2P lending platforms aim at providing a fixed income to lenders. To ensure efficient and sustainable financial intermediation, P2P lending platforms need to ensure that they are not subject to principal-agent problems and that their incentives coincide with those of lenders. The possibility of orderly resolution of P2P lending platforms failures might decrease moral hazard problems that are inherent in the modern financial intermediation.},
