AbstractHuman settlements are usually nucleated around manmade central points or distinctive natural features, forming clusters that vary in shape and size. However, population distribution in geo-sciences is often represented in the form of pixelated rasters. Rasters indicate population density at predefined spatial resolutions, but are unable to capture the actual shape or size of settlements. Here we suggest a methodology that translates high-resolution raster population data into vector-based population clusters. We use open-source data and develop an open-access algorithm tailored for low and middle-income countries with data scarcity issues. Each cluster includes unique characteristics indicating population, electrification rate and urban-rural categorization. Results are validated against national electrification rates provided by the World Bank and data from selected Demographic and Health Surveys (DHS). We find that our modeled national electrification rates are consistent with the rates reported by the World Bank, while the modeled urban/rural classification has 88% accuracy. By delineating settlements, this dataset can complement existing raster population data in studies such as energy planning, urban planning and disease response.

Trong khoảng 10 - 15 năm gần đây, ở Việt Nam đã nổi lên luận điểm rằng: cải cách thể chế kinh tế ngày càng đóng vai trò quan trọng hơn trong tiến trình đổi mới. Khi các nguồn lực như tài nguyên thiên nhiên, lao động giá rẻ và vốn...đã đến giới hạn thì cải cách thể chế trở thành đòi hỏi tất yếu đối với nền kinh tế. Tuy nhiên, đây cũng là thử thách khó khăn của quá trình phát triển. Trên thế giới, nhiều quốc gia chỉ đạt được một phần mục tiêu của cải cách, thậm chí ở một số quốc gia nỗ lực cải cách thể chế lại đẩy nền kinh tế vào những bất ổn không ngừng.  Tiến trình cải cách thể chế kinh tế sẽ khó thể thành công nếu không đi kèm với nỗ lực thiết lập một nền tảng quản trị quốc gia vững mạnh.

Turkey has been under the middle-income country category according to the income category classification of the World Bank. Turkey promoted to high-middle-income group in 2005 after spending more than 50 years in lower-middle-income group. The purpose of this study is to identify the presence of middle-income trap in Turkey. The study brings together the most recent theoretical studies from different perspectives with respect to the presence of MIT in Turkey along with Robertson and Ye approach in the empirical phase. Within the context of this study, structural break unit root test using current data obtained through the Atlas method is applied in order to evaluate Turkey’s middle-income trap status. The GNI per capita Atlas Method (current US $) data of the World Bank for the years 1967-2016 are used in the study. The empirical analysis briefly showed that Turkey is not in the MIT.

South Africa has neither a developed nor a typical underdeveloped economy. Too often it has been wrongly classified, along with, say, Australia and New Zealand, as one of the peripheral developed countries, because only a part of the economy and population have the characteristics we associate with that group. Yet its economy is distinctly different from others in sub-Saharan Africa. South Africa falls squarely into the category which the World Bank classifies as ‘upper middle-income’ developing economies, with G.N.P. per capita in 1982 ranging from $2,000 to $7,000 and averaging $2,500, thereby including South Africa, with $2,700.1 (By contrast, Kenya's G.N.P. per capita was $400 and Britain's $10,000). The World Bank's group includes Algeria, Argentina, Brazil, Chile, Mexico, South Korea, Venezuela, and Yugoslavia. South Africa shares many structural economic characteristics with these semi-industrialised countries.
