Longitude Matters: Time Zones, the location of FDI, and Trade
In recent years a lot of attention has been paid to geographic latitude and its relationship with key variables like economic growth, development, and institutional quality. In this paper we show that longitude (time zones) also matters. Using bilateral Foreign Direct Investment (FDI) data and gravity model estimations, we find that time zones have a significant impact on the location of FDI. F...
متن کاملSome Reusability Exercises in Persistent C *
Software reuse within an integrated programming environment has several advantages. The persistent programming language pC extends the language C with two simple operations, one to store objects of any type in a file, and the other to retrieve objects. This paper shows how pC allows software reuse within the dynamics of a programming language environment. Functions can be made persistent and re...
متن کاملLatitude and longitude vertical disparities.
The literature on vertical disparity is complicated by the fact that several different definitions of the term "vertical disparity" are in common use, often without a clear statement about which is intended or a widespread appreciation of the properties of the different definitions. Here, we examine two definitions of retinal vertical disparity: elevation-latitude and elevation-longitude dispar...
متن کاملAnimal Navigation: Longitude at Last
Newly hatched sea turtles exposed to artificially generated magnetic fields with parameters characteristic of two sites 3700 km apart, differing only in longitude, can distinguish the two apparent locations and orient appropriately.
متن کاملSome Peculiarities in Longitude Distribution of Sunspot Groups over Last Four Eleven-year Solar Cycles
This paper considers a longitude distribution of sunspot groups over 1982–2013, using data from the National Geophysical Data Center (Boulder, USA). The space-time distribution of sunspot groups is analyzed in coordinate sectors calculated from heliographic longitudes of the groups. A longitude extent of a coordinate sector is compared to the average size of one active region (30–40°). Then, in...
