Locational Data And The Public Interest, William A. Herbert, Micahel Goodchild, Richard Appelbaum, Jeremy Crampton, Gary Langham, Krzysztof Janowicz, Mei-Po Kwan, Katina Michael, Lisa Schamess

Publications and Research

This article presents a paper developed by the AAG Organizing Committee on Locational Information and the Public Interest through a summit held in Santa Barbara, California in June 2022. The summit resulted in goals and ideas for addressing the issues that arise from the present environment for geodata, whereby public, private, and third-sector entities can tap into publicly available locational information with relatively little regulation on its access or use. The Committee articulates four goals: (1) develop a research agenda extending across disciplines, (2) outline educational resources and strategies to guide ethical practice, (3) devise a pathway to increase public …

The Parenthood Gap: Firms And Earnings Inequality After Kids, Rebecca Jack, Daniel Tannenbaum, Brenden Timpe

Upjohn Institute Working Papers

We document the dynamics of career paths around parenthood, capturing worker advancement within firms and across firms with differing pay rates. Using a new linkage between administrative data on U.S. workers’ fertility and labor market histories, we show that the parental earnings gap is partly explained by mothers transitioning to lower-paying firms. Firm downgrading is driven by parents who take an extended absence from the labor force. Mothers who move to lower-paying firms see improved job amenities but less generous fringe benefits. The firm’s contribution to the parental earnings gap rises over time and reaches one-third by the child’s 11th …

A Critical Appraisal Of Poverty In The Context Of Nature-Based Communities: Selected Cases From The Philippines, Carla Edith Gonzales Jimena

Dissertations and Theses

The Philippines is considered one of the wealthiest countries in both Southeast Asia and the world when measured by biodiversity, mineral resources and natural resources. It is also one of the most highly mineralized countries on earth. However, despite these natural endowments, when measured by established economic and human development indices the Philippines remains poor. Using critical perspectives derived from Marxist tradition, William Chambliss' theory of law and its dialectical nature, Immanuel Wallerstein's World Systems Theory, and Fred Block's structural mechanism of the state, this study aimed to critically appraise the persistence of poverty in nature-based communities in the Philippines. …

The Establishment Of Turf Farming In Tsukuba City, Japan, Atsushi Onodera, Shizue Kamikihara, Takehiro Morimoto

The Geographical Bulletin

Formative processes of a turf producing region are examined in Tsukuba City, the leading turf producing area in Japan. Turf production in Tsukuba City is carried out together by turf traders and landscape gardeners. Due to the urbanization of Tsukuba City, almost all farms are now operated part time. Since even elderly farmers can easily produce turf, turf production has become a widely accepted activity. Moreover, a golf course construction boom has lead to a greater demand in turf production and to high prices of turf.

Farm Chemicals As Indicators Of Sediment Sources In Iowa Rivers, Edward N. Nealson, George P. Malanson

The Geographical Bulletin

Determination of the source of sediment in rivers and streams is important in order to effectively implement a program to reduce its concentration. This project uses agricultural chemicals as indicators of current sources of sediment from farm fields in the Cedar River, Iowa watershed. We hypothesized that the relations of sediment, nitrogen, and phosphorous yields to precipitation would indicate whether sediment originated from erosion of fields or from channel bank erosion of floodplains. The changes in sediment, nitrate, and phosphorus in the channel in response to rainfall events were determined. In simple regressions, all three variables have similar slopes when …

Agricultural Drought Mitigation In Carroll County, Maryland, Teresa Kaltenbacher

The Geographical Bulletin

Carroll County, with its longstanding tradition in agriculture, has had many past experiences with drought. This paper examines drought as it pertains to the farming community in the county. Precipitation statistics for the past 30 years are analyzed in context of the drought occurring in the summer of 1991. Crop loss and the subsequent implementation of federal emergency relief programs by the administering agencies within Carroll County are investigated and an assessment of their overall effectiveness is determined. Various coping strategies and perceptions of drought on an individual level are explored based on a field interview with a Carroll County …

The Urban Surface Of Shanghai Proper, Li Jinan, Tao Kanghua

The Geographical Bulletin

Based on data from aerial photographs the form, material component, and structure of the urban surface of Shanghai Proper are quantitatively mapped, classified, and analyzed. Relationships between the characteristic of the land cover and urban problems are identified. Urban surfaces include natural features such as open water and culture surfaces such as tile roofs, and concrete surfaces. A quantitative analysis of the land cover reveals the historical development of Shanghai and the emergence of an urban basin with the taller buildings at the perimeter, not in the central city. The study also reveals sections of the city where natural hazards …

Projections And Perceptions-Editoria Comments. Places, Daniel Jacobson

The Geographical Bulletin

I grew up in Newark, New Jersey. I loved its streets and its people. I loved the public schools, the No. 13 trolley that carried passengers down Clinton Avenue to the downtown area, to Bamberger's, Hahnes' and Kresge's, to the Newark Museum and especially the public library. For eighteen or more years I had never been outside of New Jersey or New York, but in the library I found the world. And I could float in my imagination to the Indian sub-continent, to China and Japan, to the great European capitals, to Oceania and beyond. I found a great fascination …

Legal Dimensions Of Rights Of Nature Applied In The Context Of The River Plym: River Plym Project Phase 1 Appendix, Jason Lowther

School of Law, Humanities and Social Sciences

This review of the literature and legal framing of so-called river rights – loosely understood by reference to the extension of certain characteristics or a particular status upon the river – has been collated in the context of the River Plym-citizenship advocacy project. It aims to examine the legal and policy potential for the attribution of ‘rights’ upon the River Plym. It does so by outlining the challenges facing the waterway, in common with many others, and noting the limitations of the current regulatory systems applied to it. The paper then offers a commentary of legal alternatives to the current …

Understanding how the traits of lineages are related to diversification is key for elucidating the origin of variation in species richness. Here, we test whether traits are related to species richness among lineages of trees from all major biogeographical settings of the lowland wet tropics. We explore whether variation in mortality rate, breeding system and maximum diameter are related to species richness, either directly or via associations with range size, among 463 genera that contain wet tropical forest trees. For Amazonian genera, we also explore whether traits are related to species richness via variation among genera in mean species-level range …

The Work Of Strangers: A Survey Of International Labour Migration By Peter Stalker., C. Nicholas Raphael

The Geographical Bulletin

As recently as the late 1980s, the migration of workers across international boundaries was a relatively minor phenomenon. Today however, the migration of workers across such boundaries as well as intercontinental movement is one of the most striking geographical aspects of the globalization of the world economy. The global landscape has developed some remarkable new economic and political features in recent years. As noted by the author-from Eastern Europe, to the Pacific Rim, to the United States-Mexican border-a reshaping of territories and alliances along with shifts of economic power have been redirecting many international flows of money, goods and most …

Improving Rail Resources: The Detroit-Chicago Rail Corridor Upgrade, A. Stroup

The Geographical Bulletin

The Detroit-Chicago Rail Corridor was awarded federal high-speed rail designation in October, 1992. This designation was the end result of a 22-year Amtrak/State of Michigan partnership created to improve the corridor's infrastructure and performance. Portions of the corridor are now able to support train speeds of up to 110 mph due to improvements to trackage and safety devices, and the elimination of some grade crossings. Facility improvements along with the infrastructure improvements have been responsible for the nearly 170 percent increase in annual corridor ridership since 1970. The continued commitment of numerous agencies has ensured that the Detroit-Chicago Corridor is …

The Catch Effort Of Spiny Lobster (Panulirus Argus) On South Caicos, British West Indies, Edward J. Burge Jr

The Geographical Bulletin

The spiny lobster, Panulirus argus, which inhabits bank around South Caicos, Turks and Caicos Islands, is the most economically important crustacean in the Caribbean region. In recent years concern regarding overfishing has become prominent. In this study 46 boat loads of specimens, with catches derived from 11 fishing sites were surveyed for data sets including size, sex, and amount from each site. The catch-per-unit effort calculated for each site revealed that individual diving ability and ease of harvest were the greatest determinants for choice of fishing site. Environmental conditions of spiny lobster habitats; such as, water depth and direction of …

Temporal And Spatial Changes In Beaver Pond Locations, Eastern Glacier National Park, Montana, U.S.A., Ross K. Meentemeyer, David R. Butler

The Geographical Bulletin

Sequential aerial photographs from 1966, 1973, 1984, and 1991 were used to map the number and distribution of beaver ponds in a portion of eastern Glacier National Park, Montana. The most stable ponds were located on deltaic environments. Ponds located on intermittent streams were somewhat less stable. A general equilibrium of pond number and site location exists in the study area throughoutthe 25-year period. This result contrasts with those from historical studies in eastern and central North America, where beaver populations at the turn of the century had probably been much lower than in Glacier National Park.

Tuan's Topophilia: The Making Of A Citation Classic, Dean Sinclair

The Geographical Bulletin

First published in 1974, Yi-Fu Tuan's work Topophilia has become one of the most cited works in human geography. Using the method of citation analysis and data from the Citation Indexes, this paper explores the frequency of Topophilia's inclusion as a reference in scholarly literature. A temporal trend is identified, which indicates that citation to Topophilia rose in the late 1970s, dropped in the early 1980s, but rose again in the late 1980s. Within journals, the references to Topophilia by geographers has declined since the 1980s while citations in literature in the humanities has increased since the late 1980s. A …

Projections And Perceptions Editorial Comments: Learning For The New World Of Work Through Geographic Inquiry, A. David Hill

The Geographical Bulletin

As students of geography, you should know that many of the competencies you will need for the world of work can be learned with geography instruction that is issues-based and inquiry-oriented. With this kind of teaching and learning, you see that what goes on in your classes is directly linked to what goes on in the real world. This learning can help you appreciate what John Dewey, the great American philosopher, believed: Education is not merely preparation for life but life itself. Indeed, it is crucial that you believe that learning is one of your most important responsibilities, and that …

The Melanesian Triad Of Unity, Ibrahim Peyon

Antropologi Indonesia

In the Melanesian worldview, humans, land, waters, plants, animals and the entire universe were created by the Creator God, and this is the essence of the original religions in Melanesia. This paper investigates this basic Melanesian philosophy, which is called the Melanesian Triad of Unity here. Oneness denotes God the Creator as the core entity, the parts of his body constituting all beings and the universe. The three principles are 1) one nation, 2) one soul and one spirit, and 3) one land and nature. All the elements are composed naturally in these three principles. As argued in this paper, …

Monroe Work's Contributions To Public Sociology, Leonard A. Steverson, Gabrielle S. Kelly, Emma R. Torres

The Journal of Public and Professional Sociology

Abstract

Monroe Work was a Chicago School trained sociologist, criminologist, and researcher who, despite not being well-known in the social sciences, produced a body of research that is exemplified in what is now known as public sociology. Work was associated with prominent sociologist and activist W.E.B. Du Bois while working in Savannah, Georgia, and later with Booker T. Washington, with whom he worked at the Tuskegee Institute, heading the records and research department. Work was a talented researcher who worked behind the scenes with both Du Bois and Washington to provide needed research in a time of intense racial conflict. …

Ecological Influences On Informal Property Rights: Experimental Evidence, Erik O. Kimbrough

Economics Faculty Articles and Research

This paper explores the possibility that informal property right systems evolve unique features as a function of the characteristics of the resources over which they are established. We develop an experimental environment that allows us to test this hypothesis by comparing the emergence of property in (virtual) land when resource yields are either high- or low-variance and renewable or non-renewable. Previous research suggests that high-variance resources may lead to relatively insecure claims to property. Intuition suggests that this may be amplified when those resources are renewable. The experiments confirm that informal property rights adapt to resource characteristics in a manner …
