title: Floods in Teresina-Piauí: a social-historical question

description: Abstract This paper approaches the phenomenon of floods as a social-historical question in Teresina-Piauí by examining the socio-spatial representations built and governmental actions to address the issue. The data source is based on information from local newspaper articles and official documents. The assumption is that floods and their impacts on the city are seen only as supernatural and/or natural disasters. These ideas have influenced the pattern of governmental actions undertaken, which are sometimes, implemented as clientelistic actions and sometimes with a technocratic bias. Thus, disregarding the political, social and historical aspects that surround the phenomenon.

title: Are Brazilian cities ready to develop an efficient urban freight mobility plan?

description: Abstract According to the Urban Mobility National Policy (UMNP), Brazilian cities with more than 20,000 inhabitants are obligated to elaborate Urban Mobility Plans (UMPs). The literature shows a lack of national research on urban freight planning and a need for better understanding issues on cargo transportation for authorities, especially regarding decision-making on policies and on urban freight transportation planning. City Logistics solutions can be considered on UMPs to reduce the problematic urban freight transport. Therefore, a survey was applied to investigate the resources available within cities to draw UMPs, the solutions for cargo movement in Brazilian cities, and the perceptions of public managers about freight transportation. The results show that “restrictions” are the solutions most adopted by Brazilian authorities, including the representative sample for cities within the São Paulo State with more than 250,000 inhabitants. The conclusions point out that Brazilian cities are not prepared to develop an efficient urban freight plan, as public managers seem to be unconscious about urban logistics demands within their cities or have neglected aspects regarding urban freight within the UMNP.

title: Statistical models for generating the plants of generic values: an application in a small municipality

description: Abstract An important source of municipal revenue, the IPTU is based on the value of the property, established by the Generic Value Plan (PVG), which is outdated in most Brazilian municipalities. Thus, the objective of this work was to use spatial econometrics to generate a model that allows determining the venal value of each property in the urban area of Rio Paranaíba/MG. The most adequate models were defined, considering the MCRL. For the models that presented neighborhood effects, the spatial weights matrix was generated, necessary for the determination of the spatial lag models and the spatial error model. By means of these, the homogenized variable was determined, which was included in the final model as an independent variable. The models that presented the most adequate were those that used the independent variable homogenized, which allowed to determine the value of each property by species that are consistent with market values. The methodology used proved to be feasible for application in small municipalities, which, together with the real estate registry, allow to update their tax collection bases and comply with the principle of tax equality. This study demonstrated the feasibility of using robust and recognized methods by the ABNT for small towns.

title: Urban form and atmospheric pollution: assessing impacts in Rio de Janeiro

description: Abstract As cities have increased their role in concentrating the world's population, they have also become critical sources of pollution. This article investigates the possible impacts of urban form on air pollutant concentrations. Given the nascent state of this research field in urban studies in Brazil, we start with a panoramic view of the problem. Then the paper discusses the state of the art on interactions between pollution, natural elements and climate conditions; explores some air pollution impacts on humans and the environment, and the literature on relations between air quality and urban form, pointing to a general lack of research in the field. It suggests a way of modeling and testing these relation in a case study in the city of Rio de Janeiro. It does so exploring statistical methods to understand the distribution of key urban pollutants, namely sulfur dioxide (SO 2 ), carbon monoxide (CO) and particulate matters (PM); along with morphological variables (ground space index and building verticality); and meteorological factors (wind direction and speed, rainfall and air temperature). Results point to grades of influence of the ground space index and building verticality on pollutants concentration and suggest new avenues for empirical and methodological work.

title: Analysis of the factors of influence and diagnosis of the management of the residues of the civil construction (RCC) in the construction sites of the city of Recife-PE

description: Abstract This article aims to identify the factors of influence of the RCC generation, as well as to diagnose waste management at construction sites in the city of Recife-PE. The identification of the factors of influence occurred through the collection of information through interviews and the application of questionnaires with those responsible for 35 construction sites. In 15 construction sites, a diagnosis of waste management was carried out, physically identifying the methods used to manage the generated waste streams. The influencing factors indicated as main aspects related to the RCC generation, the overconsumption of materials, complexity and alteration in the projects, besides the constructive processes involved. The diagnosis made on the management of RCC showed that 15 construction sites did not have complete waste generation data; 8 construction sites had ISO 14001 certification, and these had a more effective way of managing RCCs to those that were not certified. There is a lack of knowledge about the consumption of materials and the production of waste inside the construction sites. An adequate evaluation will allow a better performance of these companies, not only in the environmental aspect but also in the survival of the same companies, creating successful ventures.

title: Homicide growth in the city Belem (Brazil): between poverty/ social vulnerability and drug trafficking

description: Abstract The relationship between poverty/social vulnerability and urban violence has been subject of numerous studies in Brazil. However, a seemingly contradictory phenomenon occurred for this explanation: there was an improvement in several social indicators in the period 2000-2010, but the incidence of homicides, a key indicator of violent crime, has increased. Given this, it is valid to suppose that, in addition to poverty/social vulnerability, other factors interfere in the occurrence of homicides. This study suggests the hypothesis that drug trafficking is one such factor. To do this, it carries out a case study on the city of Belem (Brazil), which begins by the investigation of the geographical distribution of the average homicide rates for the period 2013-2015 in the neighborhoods located in the continental area of the city. It then develops a statistical analysis of the same data based on the comparison of two linear regression models, one with only variables related to poverty/social vulnerability; and another that, besides these variables, adds the number of drug trafficking occurrences. The results showed that the second model had better explanatory power than the first one. This corroborates the hypothesis that drug trafficking is a contributing factor to the increased incidence of homicides.

title: Growing-city pollution and sanitation: causality and evidence from major cities of southwestern Nigeria

description: Abstract Growing-city pollution is seen as an inability of an existence infrastructural facilities to support the growing population of humans or other living species in that environment. Growing-city pollution amidst the world has become a topic of increased scholarly review. Yet, insignificant attention has been given to how rising city-pollution influences public health and standard of living. This paper examines the link between growing -city pollution and sanitation. Analysis uses cross-sectional data to examine this causality using an evidence of high populated cities in Southwest, Nigeria. About 6.2% uses modern toilet facilities and about 67% practises open defecation. Access to water/sanitation facilities, distance to nearest health clinic or hospital are the main features influencing multidimensional poor sanitation/hygiene index. Focus Group Discussions (FGDs) revealed that discussants lacked an understanding of the linkages between hygiene practices and water-related diseases. Growing-city pollution influences endemic chronic diseases because sanitation is poorly accessible. Interaction between sanitation and population density in predicting poor health outcomes as evidenced in this study. Efforts should be geared by all stakeholders to boost and create livelihoods activities that can curtail rural-urban drift. Rural migrants should be encourage to stay in their vicinity to enjoy less air-polluted environment and decent accommodation.

title: Reflections on book and reading policies of the municipal secretariats of education of the State of Rio de Janeiro

description: abstract This article aims to analyze issues related to the composition of collections and the organization of school libraries in the municipal educational networks in the municipalities of the State of Rio de Janeiro. The analysis presented are part of the research about "Childhood, language and school: a literary reading in question", developed in PPGE-UFRJ, whose results came about through from the responses to the questionnaire distributed to the 92 municipal departments of education of the State of Rio de Janeiro and that had a response rate of 62 (67%). To support the analysis about the establishment of these library collections, this essay dialogues with the work of Britto (2011), Chartier (1996), Corsino (2010) and Paiva (2012). In order to offer a reflection about these libraries, we anchor our work in studies by Campello (2010), Mollo and Nobrega (2010) and Perrotti (2004). Some results stood out: the important place occupied by the municipal departments of education in buying collections for public schools, beginning at kindergarten level; the choice of printed materials and children's literature books; and the configuration of the library as a place for books and the important role that reading has in elementary education.

title: Green Tea Attenuates Hypotension Induced by Physical Exercise: A Randomized, Placebo Controlled Study

description: Abstract Background: Studies have shown that chronic administration of green tea decreases blood pressure (BP) at rest, while a single exercise session also promotes reduction of BP. Objective: To investigate whether if a single dose of green tea prior to aerobic exercise session improves post-exercise hypotension (PEH). Methods: Randomized, double-blind, placebo controlled study. Fifteen hypertensive patients (53 ± 3.3 years) participated in two study sessions: green tea+exercise (GTE) and placebo+exercise (PLE). Thirty minutes after ingesting 2 g of green tea or placebo, they performed 60 minutes of treadmill walking at 60 to 85% of maximum heart rate. BP was measured at rest and at every 10 minutes after exercise for 60 minutes. Blood samples were taken before ingestion of green tea or placebo and immediately after exercise to determine malondialdehyde (MDA) and nitrite (NO) concentrations. Results: On PLE day, systolic PEH was detected at all post-exercise time points (BP reduction by 6.5-11.8 mmHg), whereas on GTE day, PEH was found only at 20 and 40 minutes post-exercise (BP reduction by 5.9 and 5.8 mmHg, respectively). BP reduction was significantly higher in PLE at 10, 20 and 30 minutes post-exercise compared with GTE. In addition, GTE resulted in hypertensive diastolic response, while on PLE day, diastolic PEH was seen only at 20 minutes post-exercise. No changes in MDA or NO concentrations in response to exercise were observed. Conclusion: Green tea supplementation prior to an aerobic exercise session attenuated systolic PEH and induced diastolic hypertensive response to aerobic exercise in hypertensive patients.

title: PHYSIOLOGICAL INDICES AND GROWTH OF ‘PALUMA’ GUAVA UNDER SALINE WATER IRRIGATION AND NITROGEN FERTIGATION

description: ABSTRACT The cultivation of irrigated guava in semi-arid areas highlights the need for information regarding its responses to irrigation water quality and the fertilization management that enables its exploitation. Thus, this study aimed to evaluate the effect of water salinity and nitrogen (N) doses on the growth and physiology of the guava cv. ‘Paluma’. The experiments was conducted in drainage lysimeters under field conditions in an experimental area at the Center of Sciences and Agri-Food Technology of the Federal University of Campina Grande (CCTA/UFCG), Campus II, in Pombal, PB, Brazil. The experiment had a randomized block design, and treatments consisted of a 5 x 4 factorial arrangement corresponding to five levels of irrigation water electrical conductivity, ECw (0.3, 1.1, 1.9, 2.7, and 3.5 dS m-1), and four N doses (70, 100, 130, and 160% of the recommended N dose). The 100% dose corresponded to 541.1 mg of N dm-3 of soil. Increments in irrigation water salinity from 0.3 dS m-1 led to a reduction in stomatal conductance, internal CO2 concentration, CO2 assimilation rate, transpiration, instantaneous water use efficiency, the number of leaves and branches, stem diameter, and absolute and relative growth rates. Nitrogen doses ranging from 378.7 to 865.7 mg of N dm-3 of soil did not affect gas exchange and plant growth. Although ‘Paluma’ guava growth was affected by increases in water salinity, these plants can be irrigated using water of up to 1.42 dS m-1 with an acceptable reduction of 10% in growth variables. The interaction between irrigation water salinity and N fertilization had no significant effect on any of the variables studied.
