This paper analyzes public transit mobility of different economic classes of Curitiba, Brazil, exploring an official smart card dataset provided by the city. With the population divided into subsets corresponding to economic strata, we characterized vital spatial-temporal transit usage patterns, such as departure times and destinations reached by different economic classes. We also constructed a network representing the common origin and destination of public transit users, enabling discovering distinct patterns. Among the results, we observe that with the increase in wealth, the morning activity is postponed (on average for 2 h), and the spatial distribution of the trips becomes more localized compared with lower classes. We also show that our model captures fairly well realistic mobility patterns exploring a cheaper and larger-scale data source by comparing our results with a household travel survey from Curitiba. Understand how people in different economic classes appropriate urban spaces help to provide subsidies for, e.g., more sustainable economic development propositions.

The aimed to characterize common beans genotypes utilizing multivariate models and artificial neural network thru the agronomic attributes and seeds dimensions. The experiment was conducted in the 2017/2018 crop season at the city of Tenente Portela - RS. The experimental design was expanded blocs, were 53 segregating F2 populations and ten cultivars considered checks, disposed in four repetitions. The accurate characterization of bean genotypes can be based in the reproductive period, cycle and seeds length. Genotypes with longer cycle increase the potential of ramifications, legume and seeds magnitude per plant and increase the seeds yield independent of the commercial group. The use of biometric approach allows revealing patterns to the genotype grouping, being the patterns magnitude dependent of the intrinsic premises to the Standardized Average Euclidian Distance, Tocher optimized grouping and Artificial Neural Network with non-supervised learning. It is defined that the Artificial Neural Network are determinant to define associative patterns, being these inferences indispensable to the common beans genotype selection that answer the agronomic attributes and seeds production.

Older adults are delaying retirement and remaining in the paid workforce longer than in previous decades. There are many potential explanations for this trend. In this study, it is hypothesized that the ease or difficulty of traveling may significantly influence the labor force participation of older adults, just as it does for other working-age adults. As they age, older adults can face a number of barriers to mobility. The hypothesis is tested using data from the 2012 California Household Travel Survey (CHTS) and propensity score matching. The paper focuses on the effects of automobile ownership and transit access on the employment status of older adults (60+), controlling for a host of characteristics associated with the likelihood of employment. The analysis shows that transportation access has a substantial and positive association with employment for older adults, particularly older adults living in low-income households (those earning less than $35,000 per year). Access to jobs by public transit is especially influential among low-income older adults who live in households without automobiles. The findings underscore the importance of enhancing the transportation environment such that it allows older adults to travel regularly on their own by car or, in dense urban neighborhoods, by public transit. Limitations to this study suggest the need for additional quantitative analysis of longitudinal data as well as qualitative analysis of data from interviews and focus groups.

Among many changes potentially induced by the adoption of ridehailing, one key area of interest in transportation and urban planning research is how these services affect sustainable mobility choices, such as usage of public transit, walking, and biking modes and lower ownership of household vehicles. In this study, by using subsamples of the National Household Travel Survey (NHTS) 2017 data, propensity score matching technique is applied to generate matched samples of ridehailing adopters and non-adopters from ten different core-based statistical areas in the U.S. Results from multivariable count data regression models built on the matched samples indicate that, on average, the count of public transit trips is greater for adopters compared against identical non-adopters in all ten areas. Regarding average counts of walking and biking trips, adopters tend to make more trips in most of the places, although a few exceptions are also found. However, the relationship between ridehailing adoption and count of household vehicles appears to be more complicated as adopters, on average, seem to have a lower or higher number of vehicles than identical non-adopters, depending on the area. One major limitation of this study is that, in the statistical analyses, effects of attitudinal and detailed geographic variables are not directly controlled for, which complicates causal interpretations of findings.

Drawing on João Loureiro’s characterization of the sfumato nature of Amazonian people, in which real and imaginary elements form a single experience, this paper analyzes the interconnection between myth and reality in Órfãos do Eldorado (2008), Milton Hatoum’s fourth novel. Understanding Amazonian culture to be imbued with impulses leading to both reason and enchantment, I argue that a transfiguration of the Eldorado myth occurs via its literary redefinition. This phenomenon emerges through dialogue with Constantine P. Cavafy’s poem, "Η Πόλις" 'The City.' Departing from the common portrayal of the Eldorado myth as a search for riches, Hatoum refashions it to represent a search for love.

Convenience and low prices have enabled ride-hailing companies, such as Uber and Lyft, to position themselves amongst the most valuable companies within the transportation sector. They now account for the lion share of activities in the platform economy and play an increasing role within our cities. Despite this, very little is known about the type of people that use them, nor the purpose and timing of trips. In addition to this, their effect on other modes, such as taxis and public transit, remains, for the most part, widely unexplored. By comparing the socioeconomic and trip characteristics of ride-hailing users to that of other mode users, we find ride-hailing to be a wealthy younger generation phenomenon. While our results show that ride-hailing is too minute and inconsequential to influence the ridership level of other more substantial modes of travel overall, when considering specific market segments, the rise of ride-hailing corresponds to a significant decrease in taxi ridership and a rise in active modes of travel. Moreover, due to the specific age, timing, and purpose of our subsample, we believe that ride-hailing may effectively reduce drunk-driving, and are convinced that as this mode increases in importance in the future, it will have a much more pronounced effect on the level of ridership of other modes as well.

The work addresses the situation of six migrant indigenous peoples who currently reside in the city of Bogotá: Los Pastos, Misak misak, Wounaan, Yanacona, Nasa and Kamëntšá biya. An interdisciplinary team developed the work; due to this, the phenomenon is analysed from dierent approaches, although with a special emphasis on health. It constitutes a reflection on the condition of being indigenous in Latin American cities from the redefinition of identities, through the challenges for the guarantee of rights outside their territories, to the reasons for migration and the characterization of the migrant indigenous’ households in the city. The book includes components of the broad discussion on indigenous studies and the common situations that they may experience when settling in Bogotá, and the importance of making visible the specific experience of each people participating in the study.

Background:Previous research has shown that public transit use may be associated with active transportation. Access to a car may influence active transportation of transit riders.Methods:Using the 2009 United States National Household Travel Survey (NHTS), transit users ≥ 16 years old (n = 25,550) were categorized according to driver status and number of cars and drivers in the household. This typology ranged from choice transit riders (ie, “fully motorized drivers”) to transit-dependent riders (ie, “unmotorized nondriver”). Transit trips, walking trips, and bicycling trips of transit users are estimated in negative binomial models against the car availability typology.Results:Sixteen percent of participants took transit in the past month; most (86%) lived in car-owning households. As income increased, car availability also increased. Transit user groups with lower car availability were generally more likely than fully motorized drivers to take more public transit, walking, and bicycle trips. Transit riders have varying levels of vehicle access; their use of combinations of alternative modes of transportation fluctuates accordingly. Transit-dependent individuals without cars or sharing cars used active transportation more frequently than car owners.Conclusion:Policies to reduce vehicle ownership in households may enable increases in the use of alternative modes of transportation for transit users, even when cars are still owned.
