Within this context, the German Aerospace Centre (DLR) has developed a new suite of global layers, which accurately describe the built-up environment and its characteristics at high spatial resolution: (i) the World Settlement Footprint 2015 layer (WSF-2015), a binary settlement mask; and (ii) the experimental World Settlement Footprint Density 2015 layer (WSF-2015-Density), representing the percentage of impervious surface. -

Cultural Reflections on the Popularity of Chinese Learning
CHAPTER 3 Cultural Reflections on the Popularity of Chinese Learning Zhao Lin The Historically Inevitable Emergence of the “Chinese Learning” Craze Recently, a cultural resurgence has occurred in China that has compelled widespread attention: the emergence of the popularity of Chinese learning.1 Many universities have established sinological academies, sinological research institutes, and a prodigious number of sinological forums with varying inter- pretations of traditional Confucianism, Buddhism, and Daoism. In every city square, all kinds of old customs and new things are borrowing from prestige of “Chinese learning.” Many major events, such as Confucian rituals at the Temple of Confucius and paying homage to the Tomb of the Yellow Emperor, have made a lot of noise with their massive displays; even the practices of geo- mancy ( fengshui), divination, and astrology are plying their arts. This inher- ently complex “Chinese learning craze” has a very strong appeal and tempers the intensity of China’s rapid economic growth and ideals of its revival as an international power. The Chinese learning craze gives the face of the Chinese cultural spirit an image in stark contrast to the “wholesale Westernization” of the early reform period in China. In relation to the global culture that emerged at the end of the cold war, this “Chinese learning craze” seems to pos- sess culturally conservative values, demanding cultural “modernization, not Westernization.” This is manifested as a conscientious national cultural iden- tity while also having imperfections -
Litter Pollution in Densely Versus Sparsely Populated Areas: Dog River Watershed
LITTER POLLUTION IN DENSELY VERSUS SPARSELY POPULATED AREAS: DOG RIVER WATERSHED Gabrielle M. Hudson, Department of Earth Sciences, University of South Alabama, Mobile, AL 36688. E-mail: [email protected]. It is commonly known that when humans populate an area that area is usually subject to some environmental degradation. One of the more common aspects of environmental degradation is litter. This type of degradation is no stranger to the Dog River watershed. For years residents have seen the rivers in this watershed covered in trash, specifically after rain events. The vast majority of the trash is a result of litter from roadsides being carried into the river via drainage pipes. This paper is a comparative study of litter in areas of varying population densities in the Dog River watershed. It seeks to distinguish between the amount of litter found in densely populated areas and sparsely populated areas, and to find out if there is a correlation between population density and litter. I utilize GIS to map population density of the Dog River watershed, and analyze and compare the amounts of litter in areas of sparse and dense populations. The results show that there is no correlation between population density and litter. It also shows that there is no difference in the amounts of litter found in densely and sparsely populated areas. Keyword: litter, population density, watershed Introduction Pollution has long been an issue in the Dog River watershed, in particular litter pollution. The extent of the pollution has not gone unnoticed. There are groups of people and organizations who have taken increased interest in the Dog River watershed with intentions of reducing pollution, including Dog River Clearwater Revival and its numerous volunteers. -
Population Growth & Resource Capacity
Population Growth & Resource Capacity Part 1 Population Projections Between 1950 and 2005, population growth in the U.S. has been nearly linear, as shown in figure 1. Figure 1 U.S. Population in Billions 0.4 0.3 0.2 Actual Growth 0.1 Linear Approximation - - - H L Year 1950 1960 1970 1980 1990 2000 2010 Source: Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat. World Population Prospects: The 2010 Revision. If you looked at population growth over a longer period of time, you would see that it is not actually linear. However, over the relatively short period of time above, the growth looks nearly linear. A statistical technique called linear regression can create a linear function that approximates the actual population growth over this period very well. It turns out that this function is P = 0.0024444t + 0.15914 where t represents the time variable measured in years since 1950 and P represents the (approximate) population of the U.S. measured in billions of people. (If you take statistics, you’ll probably learn how to obtain this function.) The graph of this linear function is shown in the figure above. (1) Just to make sure that you understand how to work with this function, use it to complete the following table. The actual population values are given. If you are working with the function correctly, the values you obtain should be close to the actual population values!

Patterns of Population Distribution and Density Help Us to Understand the Demographic Characteristics of Any Area. the Term Popu
B.A. PART - 3 ( POPULATION GEOGRAPHY : PAPER - 7) TOPIC : PATTERNS OF POPULATION DISTRIBUTION IN THE WORLD - Prof. KUMARI NISHA RANI Patterns of population distribution and density help us to understand the demographic characteristics of any area. The term population distribution refers to the way people are spaced over the earth’s surface. Broadly, 90 per cent of the world population lives in about 10 per cent of its land area. The 10 most populous countries of the world contribute about 60 per cent of the world’s population. Of these 10 countries, 6 are located in Asia. FACTORS INFLUENCING THE DISTRIBUTION OF POPULATION A. Geographical Factors (i) Availability of water: It is the most important factor for life. So, people preferto live in areas where fresh water is easily available. Water is used for drinking, bathing and cooking – and also for cattle, crops, industries and navigation. It is because of this that river valleys are among the most densely populated areas of the world. (ii) Landforms: People prefer living on flat plains and gentle slopes. This is because such areas are favourable for the production of crops and to build roads and industries. The mountainous and hilly areas hinder the development of transport network and hence initially do not favour agricultural and industrial development. So, these areas tend to be less 1 populated. The Ganga plains are among the most densely populated areas of the world while the mountains zones in the Himalayas are scarcely populated. (iii) Climate: An extreme climate such as very hot or cold deserts are uncomfortable for human habitation. -
