The Difference and Combination of

Quantitative and Qualitative Research

Abstract: Quantitative research and qualitative research are two basic paradigms and methods, each with different concept, nature, fundamental theory, and research process. Recently, there are more and more arguments about the tow methods and more and more scholars promote the combination of them in researches. This thesis demonstrates the differences between the two methods and also analyzes the combination of them and its significance in researches.

Key words: Quantitative research, qualitative research, difference, combination

Section One The Introduction of Quantitative Research and Qualitative Research

There are two paradigms in social science research. One is the positivist methodology and the other is the humanist methodology. The positivist methodology simulates the natural science and uses inductive method to discover new knowledge, uses the “hypothesis-deduction” mode to test theory (Kerlinger, 1964), uses the method of mathematical statistics to analyze quantizable empirical observation and to assure the cause-and-effect relationship. In comparison, the humanist methodology derives from humanist science and emphasizes collecting, comprehending and explaining documents.

The Main Difference Between My College Life And My Middle School Life

It is generally accepted by college students that the main difference between middle school and college life lies in the degree of independence. As for me, I prefer the more independent life in university for the following three reasons. First and foremost, since the very day I entered the university, I have learned to live on my own and cultivated the habit of solving problems by myself. Without parents company, I have learned to arrange my daily meals for myself, wash clothes, set financial plans and make decisions relying on myself. Besides, college life is academically different from that in middle schools. Teachers in university only give students due guidance at due time, which renders college students more freedom to set academic goals. What’s more, we can choose any courses we are interested in and the teachers whose teaching styles are to our preference. Last but not least, we enjoy more free extracurricular time. We can make good use of the free time to broaden our views and make more friends.

The Main Difference between My College Life and My Middle School Life

Before students enter the university, they all want to know the main difference between college life and middle school life. According to my experience, college life has more freedom than the life in middle school. As for me , I prefer the more free life in university for the following three reasons. First, our studying becomes unconstrained. At the middle school, we spend most of our time studying. We have many courses and a lot of work waiting for us to complete. We try our best to study because we all want to go to better universities. But in university, it’s different. We have more time not only for studying but also for many other things. Scores are not the only standard for our life. Besides, we have more freedom in our daily life. In middle school, we always controlled by our parents and teachers. However, we can arrange our time without parents’ company in college life. Last but not least, we enjoy more free extracurricular time. The only thing we can do in middle school is studying. We have no spare time to do what we want to do. But it’s totally different in our college life. We have more free time to take part in various kinds of activities, such as dancing, playing different kinds of balls, which make our life more colorful and meaningful.

The Main Difference Between My College Life and My Middle

School Life

As we all know, life in college differs from that in the middle school in many aspects. From where I stand, I would say that the main difference between my college life and my middle school life lies in the fact that college provides a more flexible study environment while the latter a rather stereotype style.

Owing to the sharp differences between the two styles, certainly I prefer the college life to the middle school one. There are two major causes resulting in my viewpoint. For one thing, college life makes ampler room for me to study, to entertain myself, and to communicate with other students, which undoubtedly does great good to enhance my knowledge. For another, it is the flexible study model that gives me a great deal of time to touch on other studies, such as arts, history, linguistics and so on, which will help me broaden my horizon and further improve my understanding about society and life.

美国文学选读

“父亲”美国梦的缘起缘灭

——舍伍德·安德森《鸡蛋的胜利》解析 《鸡蛋的胜利》是美国著名的小说家舍伍德·安德森传世佳作之一。舍伍德·安德森生于美国俄亥俄州卡姆丹镇，后移居到克莱德镇，而且他的很多小说就以克莱德镇为背景进行创作，《鸡蛋的胜利》就是其中一篇。舍伍德·安德森能洞悉人们是如何追求美国梦的，也明了他们梦想是如何破碎的。在这篇小说的主人翁是“父亲”，一个本性天生乐观、热情，后来变得习惯性地沉默与失意的男人。安德森通过对“父亲”由原来胸无大志到后来雄心壮志再到最后梦想破碎的简单的描写，点明了本文的主题：美国梦的破灭；而文中的“鸡蛋”则可以说是美国梦的化身。那么，美国梦到底指什么呢？是什么刺激了“父亲”美国梦的产生？有时什么使得他的美梦破产了呢？本文将针对这些问题对《鸡蛋的胜利》进行解析。

首先，我们来探讨一下什么事“美国梦”？所谓的美国梦是指一种信任只要在美国经过努力不懈的奋斗便能获得更好生活的理想，亦即人们必须透过自己的工作勤恳、勇气、创意和决心迈向饭桶， 而非依附于特定的社会阶级和他人的援助。通畅这代表了人们在经济上的成功或是企业家的精神。在《鸡蛋的胜利》一文中，“父亲”的美国梦就是出人头地，能有所成功。所以，为了实现他的美国梦，他展开了他的冒险之旅：养鸡和开饭馆。但是，因为各种各样的原因，两个计划都失败了。一系列沉重的打击使得“父亲”的激情彻底消退，这也标志着他的美国梦彻底破灭。

在小说的最开始处，作者就告诉我们：“‘父亲’天生就是个乐观、热情的人。”他过着简单、快乐和满足的生活，从没想过要往社会上层爬，或是成为什么大人物。他每天过着规律的生活：平日到农场帮工挣钱，周六骑马到镇上喝几杯啤酒乐呵一下就按时回家；然后替他的马儿清洗一下就进入梦乡。可以说“父亲”的单身生活非常快乐，甚至是浪漫的。然而，一切似乎在他三十五岁那年结束单身生活后改变了。“父亲”娶了一个乡村小学女教师并且在次年就生下了“我”。在知识女性母亲的开导与启发下，“父亲”逐渐变得有雄心了，想着要出人头地。

一、说说Memcached优化方案

Memcached 是一个高性能的分布式内存对象缓存系统，用于动态Web应用以减轻数据库负载。它通过在内存中缓存数据和对象来减少读取数据库的次数，从而提供动态、数据库驱动网站的速度。 我想说：discuz官方论坛使用的正是Memcached内存优化方案，但是建议个人站长不要跟风，因为它的确不适合我们，Memcached作为高速运行的分布式缓存服务器主要用于分布式缓存，很多站长认为它会优化 PHP，其实不是这样的，所以很多站长使用Memcached优化方案后觉得速度上和没安装Memcached前没什么区别，就是因为这个道理。discuz官方很可能是集群部署方案，采用Memcached接口当然是没有问题的。

二、说说eAccelerator

eAccelerator是一个自由开放源码php加速器，优化和动态内容缓存，提高了php脚本的缓存性能，使得PHP脚本在编译的状态下，对服务器的开销大大消除。 它还有对脚本起优化作用，以加快其执行效率。使PHP程序代码执效率能提高1-10倍。

我想说：这回eAccelerator才是php加速器，而刚才讲到的Memcached是内存优化器，二者本质上是有区分的。

eAccelerator主要用于单机PHP提速，缓存中间数据.对于实时性高，但数据操作量小的情况下，非常实用.

memcached用于分布式或者集群系统，多台服务器可以共享数据.对于实时性高，同时数据操作量大的情况下，非常实用.

所以如果您的站点不是分布式部署可以考虑用eAccelerator加速php。

三、说说Alternative PHP Cache(APC) 通常就用三个大写字母APC表示

简介：Alternative PHP Cache (APC)是一种对PHP有效的开放源高速缓冲储存器工具，他能够缓存Opcode(目标文件)的php中间码。 我想说：现在用的最多的可能就是APC了，因为它直接集成在php里了，只要在编译时加上参数就可以直接使用，而不用另外去下载插件。当初apc是几个opcode缓存器里最烂的,所以当时成天有人拿出来吐嘈(包括当时国内的phpe), 不过随着apc被php官方采纳，由php 团队维护后，前景开始明朗，而且apc开始拟定进军标准包计划。
