Books,Places, Regions—A Natural Blend

Abstract

Children love books, and through carefully chosen ones geographic concepts can be conveyed. Books are good resources—great background material for describing a place, emphasizing the culture of a region, highlighting a geographical issue, or clarifying where a place is in the world. This article explains how literature encourages geographic thinking, builds geographic skills, and develops lasting mental maps of places and regions.     

A Review of “Politics of Urban Runoff: Nature,Technology, and the Sustainable City”

California sage scrub (CSS) is a highly threatened vegetation community in coastal Southern California, 90 percent of which has been lost. Understanding CSS recovery is critical to its survival. This study compares long-term effects of grazing, cultivation, and mechanical disturbance in Southern California by tracking the extent of exotic grassland in two valleys in the Santa Monica Mountains over sixty years using aerial image analysis. Native shrubs returned to the grazed valley over one and one-half times faster than they did in the cultivated valley. Cultivation might result in a type conversion of CSS to exotic annual grassland that resembles a new steady state.     

Executive Committee Meeting,Washington, D.C. January 28–29, 1972

This study compares how humans and neural networks classify climate types. Human subjects were asked to classify climates from monthly temperature and precipitation patterns. To model their learning process, the same data were used to produce input vectors that trained a pattern associator neural network. Both human subjects and the neural network classified climates accurately after 10 rounds of supervised learning. The neural network successfully modeled the rate of human learning and the ability to learn specific climate categories. Moreover, the neural network weights used to classify climates correspond to distinct visual characteristics in temperature and precipitation. These results suggest that neural networks can model the formation of visual categories.     

Who Is More Willing to Pay for Green Electricity? A Case Study of Anyang City,China

Green electricity (GE) is of great importance for effectively combating climate change and global Sustainable Development Goals (SDGs). The willingness-to-pay (WTP) for GE by end users has great influence on its widespread application, especially at the household level. Researchers have analyzed the mechanisms of residents’ WTP and predicted how much they could afford for GE. However, most of these studies have focused on developed (affluent) countries and regions, and residents’ WTP as well as the corresponding monetary amount of their WTP were not considered together in previous studies. In this study, we try to fill the gap of the inadequate research of residents’ WTP in underdeveloped areas through an analysis of the WTP of urban residents in a small Chinese city (Anyang). A total of 274 household-scale samples were collected by face-to-face interviews in December 2019. We found that approximately 60% of respondents gave a positive response to WTP, with an average value of 8.39 yuan per month. Educational attainment, per capita disposable income in the household, the length of residents’ time living in urban areas and the rate of neighbors’ approval of WTP are all positively correlated with the tendency of the residents’ positive response toward WTP. The three factors of per capita disposable income, the rate of neighbors’ approval of WTP and the degree of residents’ environmental concerns are positively correlated with the amount of residents’ WTP. More importantly, we demonstrated the existence of a weak “Herd Effect” in residents’ views of WTP. Finally, some suggestions for policymakers are given, such as raising household income through retraining and raising residents’ environmental awareness through education and community advertisements. This study also highlights that the widespread application of GE at the household level will be of great assistance to the GE industry overall. Therefore, the rising economic cost of GE should not be shared by the households in the long term.     

Change in the World City Network, 2000–2012

This article presents a large-scale analysis of the trajectories of individual cities and regions in the world city network between 2000 and 2012. The methodology used to examine cities' evolving network centralities is based on advanced producer services firms “interlocking” cities through their worldwide distribution of offices. We do not limit our analysis to a limited set of putative world cities, but incorporate 157 cities from all world regions into this global urban analysis. Absolute and relative measures of change are developed to reveal the major dimensions of change. The most notable finding is that significant connectivity gains have been limited to a small set of cities (Dubai, Shanghai, Beijing, and Moscow in particular) in the face of persisting core–periphery patterns at the level of the global economy, with New York and London remaining firmly at the apex. At the same time, overall levels of connectivity in the world city network have clearly risen, suggesting an increasingly integrated network. In geographical terms, a west-to-east shift is discernible, albeit uneven.     

Legal Geographies—The Right to Spaces for Social Dancing in New York City: A Question of Urban Rights

As municipalities have enforced laws meant to enhance "quality of life" in gentrifying neighborhoods, controversies have erupted over the legitimacy of such laws. This study investigates one such controversy in New York City. It focuses on how the denial by the courts of social dancing as constitutionally protected mode of expression has led to the judicial endorsement of the municipality's cabaret law regulating the spaces for social dancing, despite the questionable legitimacy of this regulation. The study also draws out two implications for urban activism associated with movements making claims for "the right to the city": first, that we should take seriously activities such as social dancing and the spaces that enable them, which are invaluable to urban life but are not constitutionally protected; and second, that we may use the notion of "urban rights" as a principle to protect these activities and spaces from gentrification and questionable governmental regulations.     

Minnesota—A Sketch

Abstract

This article reports the results of an exploratory project to determine the abilities of Grade 6 children to work with digital data. The research questions dealt with understanding what is digital data, understanding what is a pixel, and how digital data can be used, making a digital map, and using pixels to determine area on maps. The results of the project showed that the children in this study were able to work with digital data, and that there is potential for using digital data on the Grade 6 level in geography instruction.
