Geographic Borders: Borders: A Very Short Introduction, by Alexander C. Diener and Joshua Hagen

Boundary: A simple introduction by Alexander C. Dina and Joshua Hagen briefly introduces the history of geographical boundaries and its impact on the world. Diener and Hagen think the border is a relatively new phenomenon, as is widely understood today. And as humans move forward, modern boundaries will no longer be impossible. As globalization continues to make the world smaller, or as saying "to flatten the world", the writer maintains this attitude and the notion of a formal border is gradually over.

At the beginning of the 21st century, numerous excellent outlines on the field of border research were published. Diener and Hagen 2012 briefly introduces border surveys of a wide range of depths that are easy to understand for those who first mentioned this topic, especially beginners. De Blij 2008 aims to empirically counter the papers of the borderless world, to provide ideals to the general reader, and to make it ideal for students who have not contacted in advance with the border survey. Popescu 2012 is ideal for readers deeply involved in theoretical problems. Readers who wish to reach the broadest academic view can refer to competitors Washl - Walter 2011 and Wilson and Donnan 2012, both of which are collections. These works also provide extensive bibliography to guide you further reading. Stein 2008 is an interesting book, a simple primer for later reading boundary theory. 2013

The border is a topic frequently talked about last year, but do you remember what the border is? The basic definition of a boundary is a physical or virtual line that divides the geographic area. However, the border is not necessarily clear, it can also be psychological. The definition of my boundary is based on specific ideas that are separated for specific reasons, and they are realistic or unrealistic obstacles. However, because there is no standard definition, everyone agrees that in 1924 the US border guard began serving our country. Changes affect almost every aspect of the initial operation, but its value is. Professionalism, honor, honesty, respect for human life, and common efforts helped form border guards from the earliest days, and today has not changed.
