Abstract The United States Department of Agriculture’s National Agricultural Statistics Service (NASS) has the responsibility of quantifying the nation’s agricultural production. Historically, it has focused on large production agriculture. With interest and activity increasing in urban areas, NASS has begun exploring how to better quantify urban agriculture. This segment of agriculture is particularly challenging to enumerate because the agricultural holdings tend to be small, diverse, widely dispersed, and more transient than the predominantly large farms in rural areas. In collaboration with the Multi-Agency Collaboration Environment (MACE), a new approach to list building was explored in a pilot study conducted in the City of Baltimore, Maryland. Using a big data approach, areas of potential agricultural activity were identified by gathering information (state and local permits, Facebook and twitter feeds, interest groups, etc.) via the web. A sample was drawn from the list, and an in-person survey was conducted to assess whether or not the identified areas had agricultural activity. The results of the pilot study are presented. Lessons learned from the study and next steps are discussed.

This paper presents an overview of prevalent bicyclist crash types in the United States, providing insights for practitioners that may be useful in planning safer networks and taking other proactive and risk-based approaches to treatment. The study compares fatal bicyclist crash types from national data with serious injury and all-severity bicyclist collisions from the state of North Carolina (NC) and the city of Boulder, Colorado. Overall, bicyclist fatalities in the United States are more prevalent in urban areas (69%) than rural areas (29%). Though the majority of all-severity crashes are at intersections, most fatal and disabling injury bicyclist crashes occur at non-intersection locations, including nearly one-third of bicyclists who die from collisions involving overtaking motorists. Top intersection crash types across national fatal and all-severity crashes in NC and Boulder include bicyclists failing to yield and motorists turning across a bicyclist’s path. However, many of the top all-severity types in the two jurisdictions differ from the top fatal crash types nationwide. These comparisons provide a fresh look at bicyclist crash type trends and have potential importance with respect to planning safer networks for Vision Zero communities, since a key finding is that locations and crash types most prevalent among fatal and serious injuries may differ from the most prevalent types for all-severity crashes. The findings could be useful to agencies lacking their own resources for risk-based assessment, but also suggest it is important to analyze higher severity crash types and jurisdiction-specific data when possible.

ABSTRACT Urban agriculture is currently carried out all over the world. The activity is characterized by its multifunctionality, contributing to food security, preservation of biodiversity, better use of urban spaces, and proper management of soil and water, in addition to contributing to increasing income and improving the quality of life of farmers who live in the cities. In the 1980s and 1990s, urban agriculture gained momentum on the international scene and, from 2005, in Brazil. Some successful experiences in the world (Detroit, Havana, and St. Petersburg) and in Brazil (Teresina, Sao Paulo, and Belo Horizonte) are briefly reported here. Then, we describe in more detail the case of the city of São Luís. The municipality is situated on an island and its rural spaces have characteristics of peri-urban areas. Agricultural production has low expression in municipal GDP (Gross Development Product). The main products are papaya, cassava, beans, bananas, coconut, and passion fruit and, among the vegetables, roselle, chives, coriander, and West Indian gherkin, traditional regional species of Maranhão cuisine. The activity has two primary groups of actors: producers and intermediaries, with 83 and 41% of them, respectively, living in rural areas. Almost all producers (92%) use their area, 79% use some sustainable fertilization practice, and 69% do not use pesticides. Production areas are small and producers need technical assistance. Transport and poor road conditions are the main challenges to bring products to the markets. The reality that came out from our study indicates the lack of public support to urban farmers in São Luís. On the contrary, successful experiences of urban agriculture have in common the convergence of public policies of urban planning, agriculture and supply, education, and health. Urban agriculture is dynamic and must be integrated into the urban ecosystem to make it possible to unveiling new perspectives on the countryside-city relationship.

AbstractLassa virus is the causative agent of a dangerous zoonotic disease distributed in West Africa. A primary reservoir host of Lassa virus is Mastomys natalensis. These mice associate closely with humans and are commonly found in villages. Consequently, previous studies of Lassa virus have focused on rural areas. The prevalence of the virus in large cities has not been studied.We conducted a study in N’Zerekore city, which has a population of approximately 300,000 residents. Small mammals were captured during a pilot study in May, and the main study was performed in August 2018. Based on the pilot study, we designed and implemented a stratified random sample to investigate the prevalence of Lassa virus among M. natalensis in N’Zerekore. The total sampling efforts consisted of 45 and 985 trapping nights in May and August, respectively. Samples of rodent tissues were screened for Lassa virus by RT-PCR.In May, we trapped 20 rodents, including 19 M. natalensis. Viral RNA was detected in 18 M. natalensis. In August, 149 small mammals were captured, including 43 M. natalensis. The prevalence of Lassa virus among M. natalensis in N’Zerekore was 23.3% (CI 95%: 11.8–38.6%). Sequencing showed that the isolates belonged to lineage IV. We detected four Lassa virus hotspots located in different parts of the city. The largest Lassa virus hotspot was found in the neighborhood of the central market, which suggests that the virus was originally introduced into the city through the market.

Transmission Pipelines

The transmission pipeline incident in Edison, New Jersey in March, 1994 raised public concerns about the safety of siting of transmission pipelines in proximity to populated areas. One of the responses to this incident was the issuance of a contract by the United States Department of Transportation (USDOT) to the New Jersey Institute of Technology (NJIT) to study this and other issues with regard to pipeline safety. The research performed by NJIT included a review of current USDOT regulations and policy with regard to siting of pipelines and related land use; a review of regulations of major industrialized countries related to same; an analysis of the USDOT’s incident database vis-à-vis proximity to neighboring land uses; and a review of local land use regulations related to proximity to transmission pipelines. The basic findings were as follows: 1. The U.S. Pipeline regulations are appropriate to minimizing risk while maintaining the viability of the pipeline industry. 2. All the regulations reviewed (i.e., US and international) approach the siting and regulation of pipelines in urban areas in a similar fashion. 3. Analysis of the USDOT incident database indicates that, in general, pipelines are sited in rural or underdeveloped areas, and damage resulting from an incident in highly developed areas is generally less then in rural areas due to the regulations restricting the allowable operating stresses in more densely populated areas.

The effective, efficient and equitable policing of urban areas rests on an appreciation of the qualities and scale of, as well as the factors shaping, demand. It also requires an appreciation of the factors shaping the resources deployed in their address. To this end, this article probes the extent to which policing demand (crime, anti-social behaviour, public safety and welfare) and deployment (front-line resource) are similarly conditioned by the social and physical urban environment, and by incident complexity. The prospect of exploring policing demand, deployment and their interplay is opened through the utilisation of big data and artificial intelligence and their integration with administrative and open data sources in a generalised method of moments (GMM) multilevel model. The research finds that policing demand and deployment hold varying and time-sensitive association with features of the urban environment. Moreover, we find that the complexities embedded in policing demands serve to shape both the cumulative and marginal resources expended in their address. Beyond their substantive policy relevance, these findings serve to open new avenues for urban criminological research centred on the consideration of the interplay between policing demand and deployment.

Abstract Introduction Cervical cancer and its etiopathogenesis, the age of women in whom it is diagnosed, average life expectancy, and prognosis are information widely covered in scientific reports. However, there is no coherent information regarding which regions—urban or rural—it may occur more often. This is important because the literature on the subject reports that people living in rural areas have a worse prognosis when it comes to detection, treatment, and life expectancy than city dwellers. Material and methods The subjects of the study were women and their knowledge about cervical cancer. The research was carried out using a survey directly distributed among respondents and via the Internet, portals, and discussion groups for women from Poland. Three hundred twenty-nine women took part in the study, including 164 from rural and 165 from urban areas. The collected data enabled the following: (1) an analysis of the studied groups, (2) assessment of the respondents’ knowledge about cervical cancer, and (3) comparison of women’s knowledge depending on where they live. Results The average assessment of all respondents’ knowledge was 3.59, with women living in rural areas scoring 3.18 and respondents from the city—4.01. Statistical significance (p < 0.001) between the level of knowledge and place of residence was determined. The results indicate that an increase in the level of education in the subjects significantly increases the chance of getting the correct answer. In the case of age analysis, the coefficients indicate a decrease in the chance of obtaining the correct answer in older subjects despite the fact that a statistically significant level was reached in individual questions. Conclusions Women living in rural areas have less knowledge of cervical cancer than female respondents from the city. There is a need for more awareness campaigns to provide comprehensive information about cervical cancer to women in rural areas. A holistic approach to the presented issue can solve existing difficulties and barriers to maintaining health regardless of the place of life and residence. Implication for cancer survivors They need intensive care for women’s groups most burdened with risk factors.

The Continuum

Abstract This study of the 2018 congressional midterms demonstrates how voting patterns and political attitudes vary across a spectrum of urban and rural areas in the United States. Rural America is no more a monolith than is urban America. The rural-urban gradient is better represented by a continuum than a dichotomy. This is evident in the voting results in 2018, just as it was in 2016. We found that the political tipping point lies beyond major metropolitan areas, in the suburban counties of smaller metropolitan areas. Democrats enjoyed even greater success in densely populated urban areas in 2018 than in 2016. Residents of these urban areas display distinctive and consistent social and political attitudes across a range of scales. At the other end of the continuum in remote rural areas, Republican candidates continued to command voter support despite the challenging national political environment. Voters in these rural regions expressed social and political attitudes diametrically opposed to their counterparts in large urban cores.

In 2007 and 2008, the mortgage market failed. It failed in a number of dimensions: Default rates rose to their highest levels since the great depression, and mortgage liquidity ground to a halt. This failure has produced recriminations: Blame has been laid at the feet of borrowers, brokers, lenders, investment banks, investors and government and quasi-government entities that guaranteed mortgages. These recent events have produced an important debate: Whether the U.S. mortgage market requires a federal guarantee in order to best serve consumers, investors and markets. My view is that such a guarantee is necessary. I will divide my argument into four areas: (1) I will argue that the United States has had a history of providing guarantees, either implicit or explicit, regardless of its professed position on the matter. This phenomenon goes back to the origins of the republic. It is in the best interest of the country to acknowledge the existence of such guarantees, and to price them appropriately before, rather than after, they become necessary. (2) I will argue that in times of economic stress, such as now, the absence of government guarantees would lead to an absence of mortgages. (3) I will argue that a purely "private" market would likely not provide a 30 year fixed rate pre-payable mortgage. I think that this is no longer a particularly controversial statement; what is more controversial is whether such a mortgage is necessary — I will argue that it is. (4) I will argue that in the absence of a federal guarantee, the price and quantity of mortgages will vary across geography. In particular, rural areas will have less access to mortgage credit that urban areas, central cities will have less access than suburbs. Condominiums already are treated less favorably than detached houses, and this difference is likely to get larger in the absence of a guarantee.

Background: Patients living in rural communities often experience pronounced health disparities, have a higher prevalence of diabetes and hypertension, and poorer access to care compared to urban areas. To address these unmet healthcare service needs, an established, academic-based MTM provider created a novel, collaborative program to provide comprehensive, telephonic services to patients living in rural Arizona counties. Objective: This study assessed the program effectiveness and described differences in health process and outcome measures (e.g., clinical outcomes, gaps in care for prescribed medications, medication-related problems) between individuals residing in different rural-urban commuting area (RUCA) groups (urban, micropolitan, and small town) in rural Arizona counties. Methods: Subjects eligible for inclusion were 18 years or older with diabetes and/or hypertension, living in rural Arizona counties. Data were collected on: demographic characteristics, medical conditions, clinical values, gaps in care, medication-related problems (MRPs), and health promotion guidance. Subjects were analyzed using 3 intra-county RUCA levels (i.e., urban, micropolitan, and small town). Results: A total of 384 patients were included from: urban (36.7%), micropolitan (19.3%) and small town (44.0%) areas. Positive trends were observed for clinical values, gaps in care, and MRPs between initial and follow-up consultations. Urban dwellers had significantly lower average SBP values at follow-up than those from small towns (p < 0.05). A total of 192 MRPs were identified; 75.0% were resolved immediately or referred to providers and 16.7% were accepted by prescribers. Conclusion: This academic-community partnership highlights the benefits of innovative collaborative programs, such as this, for individuals living in underserved, rural areas.

A intensa urbanização causa diversos problemas de natureza ambiental, climática e social. O crescimento não planejado da população urbana e a remoção da vegetação são fatores que intensificam estes problemas. As temperaturas na cidade são significativamente mais quentes do que as suas zonas rurais circundantes devido às atividades humanas. As intensas mudanças espaciais em áreas urbanas, promovem significativo aumento na temperatura, causando o chamado efeito de Ilha de Calor Urbano (ICU). Campina Grande é uma cidade de tamanho médio que experimentou um crescimento desordenado, desde o tempo do comércio de algodão e, como qualquer cidade de grande ou médio porte, sofre alterações em seu espaço. Dessa forma, este estudo teve por objetivo analisar a variabilidade espaço-temporal da temperatura da superfície (Ts) e detectar ICU, através de técnicas de sensoriamento remoto. Para o efeito, foram utilizadas imagens dos satélites Landsat 5 e 8, dos anos de 1995, 2007 e 2014. Aumentos da Ts foram bem evidentes e foram detectadas duas ICU. Campina Grande mostra um padrão de tendência: o crescimento urbano não planejado é responsável por mudanças no ambiente físico e na forma e estrutura espacial da cidade, o que se reflete sobre o microclima e, em última análise, na qualidade de vida das pessoas.   ABSTRACT The intense urbanization causes several problems of environmental, climate and social nature. The unplanned growth of urban population and the vegetation removal are factors that deepen these problems. Temperatures in the city are significantly warmer than its surrounding rural areas due to human activities. Large spatial changes in urban areas promote significant increase in temperature, causing the so-called Urban Heat Island effect (UHI). Campina Grande is a medium-sized town that experienced an uncontrolled growth since the time of the cotton trade and like any large or medium-sized city, undergoes changes in its space. Therefore, this study aimed to analyze surface temperature spatial and temporal variability and to detect potential UHI, through remote sensing techniques. Spectral images from Landsat 5 and 8 satellites were used. Using images from years 1995, 2007 and 2014, considerable increases in temperature were identified and two UHI were recognize. Campina Grande shows a trend pattern: the urban unplanned growth is responsible for changes in the physical environment and in the form and spatial structure of the city, reflecting on people quality of life. Keywords: change detection, surface temperature, heat islands, urbanization.
