title: Routing for safer rides: a space syntax approach to predict bicycle collisions in a Brazilian city

description: Abstract In order to broaden the discussion on the safety of bicycle transport, this paper uses the analytical capacity of the spatial syntax applied to the recording of accidents involving cyclists in the city of Rolândia-PR, located in the Southern Region of Brazil. With the availability of 535 reports of trips made by bicycle mode, collected in the survey origin and destination of the city, a database was elaborated where each segment of the road received its numerical value from the loading of trips, and its corresponding values of choice and integration, generated in the Depthmap software. As a result, the relationship between the point of accident and the trip record by bicycle was refuted. In contrast, the angular values of choice and integration were sufficient to explain the occurrence of accidents involving cyclists in each segment of the municipal urban network, statistically proven through the generation of a generalized linear model. The contribution of this study focuses on the validity of using spatial syntax to predict safer routes, which is considered a theoretical-methodological approach that identifies priority routes for the implementation of specific infrastructure for bicycle transport.

title: Relations between CEO characteristics and mergers and acquisition decisions in Brazilian companies

description: ABSTRACT This paper investigates the probability of companies to perform Mergers & Acquisitions (M&As) based on the characteristics of the CEO.. We use a sample of 794 CEOs of nonfinancial firms, which were listed on the B3 from 2000 to 2017. We adopt a descriptive approach and run logistic regressions to examine the probability of a company performing M&As, given the characteristics of its CEO. We show that CEOs with finance backgrounds are less likely to perform M&As. We find no statistically significant correlations for other CEO’s characteristics, such as executive tenure, age, education, participation as chair of the board, previous experience as an entrepreneur or being a shareholder of the acquiring company.

title: Damming in the Madeira River modifies the food spectrum of piscivorous and affects their resource partitioning

description: Abstract Phylogenetic proximity suggests some degree of diet similarity among species. Usually, studies of diet show that species coexistence is allowed by partitioning food resources. We evaluate how visually oriented piscivorous fishes (Characiformes) share prey before and after building the Santo Antônio Hydroelectric Power Plant (HPP) in the Madeira River (Brazil), the largest muddy-water tributary of the Amazon River. Piscivorous species (Acestrorhynchus falcirostris, Acestrorhynchus heterolepis, Hydrolycus scomberoides, and Rhaphiodon vulpinus) were sampled under pristine (pre-HPP) and disturbed (post-HPP) environmental conditions. We analyzed species abundance and stomach contents for stomach fullness and prey composition to check variations between congeneric and non-congeneric species. The percent volume of prey taxa was normalized by stomach fullness and grouped into the taxonomic family level to determine diet, niche breadth, and overlap. Only R. vulpinus abundance increased in post-HPP. There was no significant variation in niche breadth between the periods, while niche overlap decreased in congeneric and non-congeneric species. Our results indicate that river impoundment affected piscivorous fishes in distinct ways and modified their resource partitioning. Therefore, evaluate interspecific interactions is a required tool to understand how fishes respond to river damming.

title: Relationship between the estimates of the Walkable Built Environment Index - ACC and Walk Score® index in Brazilian cities: case of Niterói, RJ

description: Abstract Policies to encourage walkability have been used to increase the urban vitality, achieved through interventions in the urban environment, These conditions can increase the potential sustainable modalities trips, directly reflecting over the quality of life. In order to observe such influence, this article intends to apply two walkability indexes, the ACC Index and the Walk Score, in the city of Niterói, Brazil, and to verify if the estimates of these two indexes are adherent to local standards of mobility. As a result, the ACC Index performed better, signaling that certain local specificities were not understood by the Walk Score®.

title: Adaptability in the Brazilian Capital Market: Aspects Associated with Efficiency Reported by Companies Listed in B3

description: ABSTRACT This article aims to verify the influence of political uncertainty, accounting elements, and the macroeconomic environment on the (in)efficiency of securities traded by Brazilian public companies. Between 2000 and 2019, we used 275 non-financial companies with shares traded in B3. We performed regression tests with panel data for two samples, one balanced and one unbalanced, totaling two models. For each model, we performed an additional analysis using the Stepwise method. The dependent variable comprises the inefficiency of daily stock data. The independent variables comprise political-economic uncertainty, the companies' accounting indicators, gross domestic product per capita, and interest rate. We used controls related to the size, liquidity of the shares, and sectors of the companies. According to the selected sample, the results show that higher rentability companies tend to increase efficiency while liquidity positively or negatively affects efficiency. In periods where interest rates are high, there is less efficiency in predicting securities. These results aim to contribute to the literature on adaptive markets by providing evidence on defining aspects of Brazilian securities' efficiency variability.

title: Mediation of Socio-environmental Conflicts in Paraná: Mining and Impacts on Public Health

description: Abstract Socio-environmental conflicts are issues result from anthropic pressure on the environment that reflect social and politics aspects, mostly where the public power does not provide solutions for the necessity of local citizens. In Brazil, there are relevant scientific works related to the theme. Most articles present a diagnostic regarding the conflict. There is a gap on studies based on theorical approaches that consider a specific case and the people involved in it. Accordingly, this paper takes into account São Mateus do Sul - PR, a city that hosts a shale mining plant. Disagreements from the citizen that claims on respiratory diseases resulted to a lawsuit by the Public Ministry of Paraná. The conflict was analyzed by Dynamic Analysis Rondeau Model (1996), to indicate other solutions, besides judicialization of conflicts. Primary data were obtained through the analysis of the content of public civil actions filed at Judiciary/PR. Take into account the challenge of the theme and the fact that the courts are filled of unsolved socio-environmental conflicts, this article brings an important issue: the evaluate of conflicts based on theorical approaches that might result in decision-makers in a short time.

title: Urban consumption in modern Iran (Case study: City of Zanjan)

description: Abstract Numerous studies have been conducted on consumption within urban spaces. However, how people from different socio-economic classes consume urban spaces has not been sufficiently studied specially in Iran. To fill these gaps, the distinguishing feature of this paper is providing answer to how people consume urban spaces in everyday life and focusing on understanding style of consumption in urban spaces considering the dominant category of purchasing, taking heed of the various socio-economic classes in lieu of merely sex issues in modern life. To this end, abductive research strategy was employed. Using data encoding method in Grounded Theory, the results were analyzed which indicated four patterns for urban consumption and 24 consumption spaces in Zanjan. These consumption spaces were studied based on six styles of consumption. The results of the study indicated symbolic consumption is the most prominent style of consumption and that in many consumption spaces in Zanjan, different socio-economic classes are segregated and people from certain socio-economic classes are mostly present and the presence of people from other classes is insignificant. While social mixing was seen in some spaces, it was found that in urban space consumption people associate meanings with the spaces which convey their desired identities.

title: School Performance and Symptoms of Depression, Anxiety, and Stress in Adolescents

description: Abstract The objective of this study was to verify the correlation between school performance and symptoms of depression, anxiety, and stress in 432 public school students aged from 15 to 18 years. The instruments used were a sociodemographic datasheet, Escala de Depressão, Ansiedade e Estresse (EDAE-A), and the grades in the courses/areas of interest of three school trimesters. Descriptive analyses, as well as the Mann-Whitney U test and Spearman's correlation test, were conducted. A weak and negative correlation was found between school performance and anxiety and depression symptoms, with the adolescents from full-time schools presenting better performance and fewer symptoms of depression and anxiety than those in regular schools. Younger adolescents presented more stress symptoms, while female adolescents have more depression and anxiety symptoms.

title: Sustainability of the usable solid waste market in Bogota (Colombia)

description: Abstract This document shows a model that seeks the sustainability of the Usable Solid Waste (USW) market in Bogotá, based on System Dynamics (SD), in order to understand the complex behavior of the phenomena that should be presented in this city market in the context of sustainability. Dynamic hypothesis suggests that two negative feedback structures exits, one that represents demand and another that represents supply and that interact under the assumption of free market with government intervention. Different strategies were modeled on both the demand side and the supply side to manage the system. As conclusion, the linear way in which the USW market currently develops is not adequate. It is necessary to institutionalize the market using the price so that it contributes to its sustainability and that both demand and supply are encouraged at the same time. Besides, district policy oriented to supply must be in accordance with the national policy that encourages demand to use more USW. Likewise, the internalization by all the actors of the market and applicability of the norm is required. The creation of public-private partnerships is required for the development of innovative projects in this area.
