Abstract (sommario):

This study examined commuting patterns among 23,141 methadone patients enrolling in 84 opioid treatment programs (OTPs) in the United States. Patients completed an anonymous one-page survey. A linear mixed model analysis was used to predict distance traveled to the OTP. More than half (60%) the patients traveled <10 miles and 6% travelled between 50 and 200 miles to attend an OTP; 8% travelled across a state border to attend an OTP. In the multivariate model (n=17,792), factors significantly (P<.05) associated with distance were, residing in the Southeast or Midwest, low urbanicity, area of the patient's ZIP code, younger age, non-Hispanic white race/ethnicity, prescription opioid abuse, and no heroin use. A significant number of OTP patients travel considerable distances to access treatment. To reduce obstacles to OTP access, policy makers and treatment providers should be alert to patients' commuting patterns and to factors associated with them.

Abstract (sommario):

The paper consists of optimizing the total distance traveled by the Plasma Cutting Tool Head. It is cross-functional implementation traveling salesman problem to the core manufacturing process of plasma cutting. This study contributes to reduce the total rapid traverse length (Total Through-Air Travelled Distance) by the cutting tool (Plasma Beam), which is totally a non-productive as well as non-value adding process contributing to the machine running costs and cycle time of the product directly and indirectly. For deriving this optimal sequence for the plasma cutting head, a heuristic algorithm is used. This algorithm calculates an optimal solution for a problem creating the best possible sequence. The greedy algorithm follows the problem-solving heuristics of making a locally optimal choice at every stage, finally integrating a globally optimal solution. Hence after deducing this optimal sequence and when accompanied by the Plasma Cutting tool, it resulted in the least distance traveled, contributing to minimizing cost and energy savings of the machine and simultaneously reducing the total traveled distance and similarly the cycle time.

Abstract (sommario):

? Forager ants search for adequate food sources in nature and, after their discovery, decide whether the source is suitable or not for the colony. However, we asked “How do workers seek out the substrate for cultivation of the symbiontic fungus on which they feed? To answer this question, we evaluated the distance traveled by individual workers in the search of food and the distance traveled to return to the nest, as well as the time and velocity necessary for these activities. The results showed that the distance traveled by the leaf cutting ant, Atta sexdens rubropilosa (Linneus, 1758), in the search of food was greater than the distance traveled to return with the substrate to the colony. On the other hand, the mean time and velocity were similar for food search and return to the colony. These results support the hypothesis of information transfer, according to which the worker needs to return to the nest at the beginning of foraging to transfer information to other workers and thus to establish the process of worker ant foraging. It can be concluded that workers travel large distances in a random manner until finding their substrate, but the return to the nest is efficient considering the shorter distance traveled.

Abstract INTRODUCTION Global oncology development within LMICs (low- and middle-income countries) requires bridging gaps in healthcare systems. Brain tumor care in Pakistan is currently sparse and concentrated in urban centers. Distance traveled to a hospital dictates a patient’s access to care, neurosurgical access, and continuity of care through adjuvant chemoradiotherapy and primary care providers can be disrupted if patients cannot overcome the barriers due to extensive distances traveled. METHODS Data was collected as part of the Pakistan Brain Tumor Epidemiology Study (PBTES) regarding patients with brain tumors who underwent surgical procedures in 2019 at private and public major neurosurgical centers across Pakistan. Using patient addresses, we used a mapping software to calculate the distance traveled by each patient to the primary hospital. Analysis was done using appropriate statistical methods. RESULTS Out of 2403 patients, the mean distance traveled across the country was 240 km. The longest distance traveled within Pakistan was from Skardu to Karachi (2002 km) for resection of a pituitary adenoma (28 hours via car). Only 48% of patients were able to reach their primary hospital within 50 km. 52% of patients had to travel more than 50 km, and 18% had to travel upwards of 500 km to reach their primary hospital. Additionally, 101 patients traveled to Pakistan from other countries for brain tumor surgery (98 patients from Afghanistan [mean distance traveled: 723.6 km], 3 patients from Syria, Oman, and Sudan). CONCLUSION Prior studies have described a cut-off of 50 km as an acceptable limit for distance from the primary hospital in cancer patients for optimal follow-up and outcomes, which is achieved by only 48% of brain tumor patients in Pakistan. Most patients have poor access to surgical care for brain tumors, further compounded by repeat traveling for follow-ups and chemoradiotherapy.

Abstract (sommario):

Background: Long-distance travel is common for professional athletes; thus, the impact of jet-lag on athletic performance is a relevant topic. Additionally, older individuals take longer to recover from exercise and post-travel fatigue; therefore, it is likely that age and travel affect performance. Objective: The purpose of this study is to investigate the effects of age and travel on NFL quarterback performance. Method: A correlational research design is used to examine the effects of age and travel on NFL quarterback performance. Data were collected from pro-football-reference.com. Quarterback ratings from the 2018 NFL season are analyzed with age, distance traveled, season week, and weeks since the team’s bye week. The interaction of age and distance is also included to examine the impact of the age-distance relationship on performance. Regression analysis is used to predict quarterback ratings. Results: Season week (p = 0.04), weeks since a bye week (p = 0.041), and distance traveled (p = 0.031) have negative effects on quarterback ratings. The age-performance relationship in NFL quarterbacks is non-linear (p = 0.018), with quarterback performance decreasing during an athlete’s 20s and then increasing during an athlete’s 30s. Additionally, ratings of younger quarterbacks decrease with farther distances traveled, while the ratings of older quarterbacks increase with farther distances traveled (p = 0.072). Conclusions: Differences in performance by age with travel may be the result of different severities of jet-lag symptoms experienced by younger and older quarterbacks, as well differences in strategies for managing post-travel fatigue by athletes of different ages.

Abstract (sommario):

The objective of this work was to analyze how the variation of traveled distance, operational speed, journey time and net cargo transported influence the fuel consumption of vehicles in forest road transport. The data were collected in this operation, covering the area between the regions of Campo do Tenente (forest unit) and Piên (industrial unit), in the state of Paraná. We analyzed the partial elements, loaded trip and empty trip, as well as the total transport cycle (loading, unloading and travel). Using the same mechanical tractor, two vehicular compositions were studied, an articulated vehicle (truck tractor + semitrailer + trailer) and a conjugated vehicle (truck tractor + semitrailer). The vehicle telemetric system was used to perform the data collection of travel time, traveled distance, speed average and fuel consumption of the both vehicles. The results showed that the higher fuel consumption occurred in the loaded trips for longer distances. The sensitivity of fuel consumption was mostly influenced by was traveled distance, so it is recommended the use of vehicles of less load capacity for shorter distances.

Abstract (sommario):

In this study, biodiesel fuel with a ratio of 20% volume (B20) was used on vehicles that are used in common rail injection systems, complying with Euro2 emission regulations. Laboratory and road tests were conducted to evaluate the effects of B20 on performance, emissions and engine components. Using diesel fuel and B20 as reference fuels, tests were conducted using Euro2 vehicle technology to investigate the effects on emissions, fuel consumption, and power. Durability testing was run for travel distances covering 40,000 km under various road and environmental conditions, while vehicle performance and emissions tests were conducted using the ECE R84-03 and ECE R101 test methods, respectively. The results show that B20 has lower CO and hydrocarbon (HC) emissions for every distance travelled, with an average of around 30%. Particulate emission was a bit lower, averaging 3.4% for B20 compared to B0, while NOx was found to slightly increase at around 2% for B20. Due to its lower calorific value, for an average distance traveled, the fuel economy of B20 was around 0.5% higher compared to B0. Furthermore, the maximum power of B20 was 3% lower compared to that of B0 for the entire distance traveled. However, an evaluation of engine components after 40,000 km showed that B20 and B0 were similar. Moreover, vehicles using B20 tend to have a comparable durability of engine components when compared with B0.

Abstract (sommario):

Between 1910 and 1970, millions of southern-born Americans migrated to the northern and western regions of the country in search of better opportunities. Some traveled only short distances, leaving Appalachia for nearby destinations in the southern Midwest. Others made the much longer trek to the West Coast. In this article, we use data from the 1920, 1940, and 1970 Public Use Microdata Samples to investigate the distances traveled by male participants in the Great Migration, with a special focus on differences by race, as well as on changes over time. We find that the average distance traveled increased substantially during the Great Migration for blacks and whites alike. However, throughout this time period, white migrants moved significantly farther than black migrants. The greater propensity for white migrants to move west, rather than north, accounts for a good deal of this overall racial variation. Although the difference in distance traveled between blacks and whites narrowed significantly over time, it remained substantial as the Great Migration came to a close. We conclude by highlighting the impact of these differential migration patterns on the composition and social conditions in northern cities.

Abstract (sommario):

6558 Background: EP-CTs are often conducted at large academic centers, which may require some patients to travel further for their care. Little is known about either the distance EP-CT participants travel for their care or the association of distance traveled with patient characteristics and outcomes. Methods: We retrospectively reviewed the electronic health records of consecutive patients enrolled in EP-CTs at Massachusetts General Hospital from 2017-2019 to obtain patient characteristics (demographics and clinical factors) and outcomes (including time spent on trial, survival, and presence or absence of an advance care planning [ACP] discussion, defined as documentation of a code status or goals of care conversation in the medical record). We also used patients’ home zip codes to derive the social deprivation index (SDI; a composite demographic measurement from 0-100 quantifying social determinants of health, with higher numbers indicating more disadvantage). To estimate distance traveled, we calculated the miles traveled in one direction driving from home zip code to trial site. We used descriptive statistics to compare patient characteristics and outcomes for those traveling < 50 miles (short distance) versus those traveling 50+ miles (long distance). Results: Among 421 patients (median age = 63.0 years, 56.9% female, 97.6% metastatic disease), median distance traveled was 36.4 miles. Half of patients (n = 217; 51.5%) traveled 50+ miles to receive care on trial. There were no significant differences between those traveling short and long distances in most patient characteristics evaluated, including age (60.9 vs 60.6 years; p = 0.635), sex (53.9% female vs 57.6%; p = 0.447), race (85.3% white vs 84.8%; p = 0.346), marital status (71.8% married vs 69.3%; p = 0.586), insurance (51% private vs 54.4%; p = 0.266), cancer type (22.5% GI vs 21.2%; p = 0.666), prior lines of therapy (52.5% one-two lines vs 51.2%; p = 0.981), and performance status (62.3% ECOG 1 vs 66.8%; p = 0.270. However, those with a higher SDI score were less likely to travel a long distance for trial participation (mean SDI 36.7 for short distance vs 30.5 for long distance; p = 0.026). Patients traveling a long distance were less likely to have a documented ACP discussion (48.8% vs 66.7%; p < 0.001). We found no significant difference in time spent on trial between those traveling short and long distances (mean days: 98 vs 93.5; p = 0.175) or in time from coming off trial to death (mean days: 147.7 vs 153.7; p = 0.099). Conclusions: We found that half of EP-CT participants travel 50+ miles in one direction to their trial site, with disparities in travel distance based on the social deprivation index. Notably, those traveling long distances were less likely to have a documented ACP discussion. Our findings suggest several unmet needs in the EP-CT population and highlight opportunities for future intervention development.

Abstract (sommario):

Neste trabalho é estimado o valor do índice de mortes por quilômetro percorrido pela frota de veículos rodoviários no Brasil e em cada estado da federação nos anos de 2004 a 2008. Para determinar os valores da quilometragem anual média dos veículos - parâmetro necessário para estimativa do índice de mortes por veículo - quilômetro - desenvolveu-se um método apropriado tomando como referência a quantidade de combustível vendida pelas distribuidoras em cada estado. Os estados foram classificados em relação a todos os índices associados à mortalidade viária, assim como analisadas as relações entre o índice de mortes por quilômetro e o nível de desenvolvimento econômico dos estados. Constata-se que a situação da mortalidade no trânsito é um grave problema nacional, sobretudo nos estados mais pobres, onde os índices de mortes por veículo-quilômetro atingem números extremamente elevados. O fato positivo é que os números apontam para uma redução contínua do índice de mortes por quilômetro, que passou de 68,26 para 55,87 mortes por bilhão de quilômetros no país entre 2004 e 2008 (queda de 18,15%). Isso se deve ao aumento da quilometragem percorrida, função do aumento da frota, do crescimento econômico e de certa estabilização do número de mortes; este último em decorrência de ações em âmbito nacional implementadas pelo governo federal, bem como de ações específicas levadas a efeito em alguns estados.
This research estimated the value of the rate of deaths per kilometer traveled by the road vehicles fleet in Brazil and in each of the states of the federation, in the years 2004 to 2008. To determine the values of the average annual distance traveled by vehicles - parameter needed to estimate the rate of deaths per vehicle-kilometers - an appropriate methodology has been developed with reference on the amount of fuel sold by distributors in every state. The states were ranked according to all indexes associated with road fatalities, and the relationship between the rate of deaths per kilometer and the level of economic development of states, expressed by the motorization rate and the GDP per capita, is analyzed. It appears that the situation of traffic mortality is a serious national problem, especially in the poorest states, where the rate of deaths per vehicle-km reaches very high figures. The positive fact is that the numbers point to a continued reduction in the rate of deaths per kilometer, which decreased from 68.26 to 55.87 deaths per billion km in the country between 2004 and 2008 (a decrease of 18.15%). This is due to the increase on the distance traveled, a result of the increased fleet and economic growth, and also of some stabilization in the number of deaths; being the last a consequence of nationwide actions implemented by the federal government, and also of specific actions carried out in some states.

Pontos de contagem é um método atrativo para utilização em programas de monitoramento de aves por ser simples e permitir que vários locais sejam amostrados. Contudo, nos estudos realizados em regiões tropicais utilizando-se deste método, os autores utilizam a variável "tempo" de forma diferente para registrar a abundância das aves nos fragmentos florestais. Portanto, os dados obtidos por estes diferentes estudos não podem ser comparados entre si, pois o tempo gasto nos pontos e o tempo total das contagens diferem significativamente, assim como as distâncias percorridas. Desta forma, o objetivo do presente trabalho foi o de comparar quatro durações de tempos distintas (5, 10, 15 e 20 minutos) para identificar qual destas registra maior riqueza e abundância de aves em fragmentos de florestas tropicais. As amostragens foram realizadas durante 12 meses em um fragmento de floresta estacional semidecidual de 2.180 ha no interior de São Paulo. Um total de 120 minutos de amostragem foi realizado a cada mês para cada tempo distinto, o que exigiu um número diferente de pontos amostrais e uma diferente distância total percorrida na floresta. Com relação à riqueza e abundância, os testes estatísticos evidenciaram que o tempo de cinco minutos apresentou resultados que diferem significativamente dos outros tempos (10’, 15’ e 20’). Além disso, houve uma correlação positiva entre as diferentes distâncias percorridas e a abundância registrada, ou seja, quanto maior a distância percorrida, maior a riqueza e abundância registradas. Um aspecto da ecologia da comunidade que deve ser levado em consideração é que as espécies são distribuídas de forma heterogênea em uma floresta, pois diferentes espécies de plantas e diferentes padrões na fisionomia da floresta proporcionam diferentes tipos de micro-hábitats para aves. Quando se utiliza um maior número de pontos de amostragem, espera-se encontrar uma maior heterogeneidade da floresta, portanto, a maior riqueza registrada pela contagem de cinco minutos está associada a um maior número de pontos necessários para isolar a variável tempo. Outro fator importante é a variação encontrada nos valores do Índice Pontual de Abundância amostrados. A menor variação e consequente maior poder estatístico ocorreu na contagem mais curta (5’ minutos), indicando que o tempo é o mais eficiente para atingir os objetivos propostos. É importante ressaltar que este período de tempo exigiu quatro meses a menos para registrar o mesmo número de espécies que as outras contagens. No oitavo mês de amostragem, o tempo de cinco minutos já acumulava 119 espécies, valor maior que a riqueza total obtida com os outros tempos. Portanto, ao utilizar o método de pontos de contagem para analisar a estrutura da comunidade de aves em fragmentos florestais, o melhor resultado foi alcançado com a contagem de cinco minutos. Este tempo provou ser mais eficiente por detectar maior riqueza e abundância com menor esforço amostral, além de aumentar a chance de se registrar novas espécies devido ao maior número de pontos realizados em um maior número de micro-hábitats na floresta.
Point counts are attractive for use in avian monitoring programs because they are straightforward and allow numerous geographic sites to be sampled. However, in studies conducted with the point count method in tropical regions, authors use the variable "time" differently to record the abundance of birds in forest remnants. Therefore, the data obtained by different studies cannot be compared since the time spent at the points and the total counting time differ significantly, as do the distances traveled. The objective of the present study was to compare four distinct point count times (5, 10, 15 and 20 minutes) to identify which registers relatively greater bird richness and abundance in tropical forest fragments. Samplings were carried out for 12 months in a 2,180 ha fragment of semideciduous forest in the interior of the state of São Paulo. A total of 120 minutes of sampling was carried out each month for each counting time, which required a different number of counting points and a different total distance traveled in the forest. With respect to richness and abundance, the statistical tests showed that five minutes of counting yielded results that were significantly different from those of the other point count times. Additionally, there was a positive correlation between the different distances traveled and the recorded abundance, i.e., the greater the distance traveled, the greater the richness and abundance. One aspect of community ecology that must be considered is that species are distributed heterogeneously in a continuous forest because different plant species and different patterns in the terrain of the forest provide different microhabitats for birds. When a greater number of sampling points is used, greater forest heterogeneity is expected; therefore, the greater richness recorded by the five-minute counts is associated with a greater number of points needed to isolate the time variable. Another important factor is the variation in the sampling rates; the lowest variation, and consequently greater statistical power, occurred in the shortest count (5′), indicating that this counting time is effective for meeting the proposed objectives. Importantly, this counting time required four fewer months to record the same number of species as the other times. By the eighth month of sampling, the five-minute count had accumulated 119 species, which was higher than the total richness obtained with the other times. Therefore, when using the point method to analyze the community structure of birds in forest fragments, the best result was achieved with the five-minute count. This time proved to be more efficient because it detected greater richness and abundance with a lower sampling effort and increased the chance of registering new species due to the higher number of sampling points over a larger number of microhabitats in the forest.

Virtual environments (VEs) have gained widespread use in recent years as a tool for training new skills, particularly in cases where training in the real environment can be risky or dangerous. But while there are many potential applications that could benefit from using VEs, our understanding of several basic perceptual and cognitive tasks in VEs - distance and traveled distance estimation, speed estimation, spatial orientation, and wayfinding - is not yet well developed. This dissertation increases understanding of two of these problems through three experiments on distance estimation and three on traveled distance estimation. The first experiment directly compared participants' distance estimates across several visual presentation methods and measurement protocols. Results, for instance, showed no significant differences between estimates made when VEs are displayed in a head-mounted or a large-screen immersive display. In the second distance estimation experiment, participants made a series of distance judgments with feedback during an adaptation phase, and then made a series of " test phase" judgments without feedback in an environment that was similar but differently scaled. Under certain scaling conditions, there were significant differences between adaptation accuracy and test accuracy, suggesting that people's perceptual judgment is less well grounded in VEs than in the real world. Finally, our third distance estimation experiment was a pilot that further confirmed underestimation of distances in VEs while providing initial experience with a travel distance task valuable for the second half of our research. The fourth experiment is one of the first to directly compare traveled distance estimates between real and virtual environments. Results, for instance, showed a significant difference between estimates made by people who were passively moved through a real environment and people who experienced simulated self-motion in a virtual environment. The fifth and sixth experiments investigated whether scene density and richness affect people's sense of traveled distanced. In each of these experiments, participants who experienced feature-sparse environments judged traveled distances significantly differently than subject who experienced feature-rich environments. However, traveled distance estimation seems to involve more cognitive factors than distance estimation, and population differences between the two experiments make general conclusions somewhat difficult without further experimentation.

Abstract (sommario):

The importance of the sweet potato whitefly to Arizona vegetable continues to ebb and flow from year to year. Over the last 25 years much of this likely is tied to the invasion by different strains. As we continue to study this insect, an aspect of importance to their management is their ability to disperse. In past studies we have determined how far they are capable of flying in a day’s time, 95% migrate 1.6 miles. We are now investigating their ability to fly multiple days. If they do migrate on more than 1 day, we must readjust our estimates of their influence on surrounding fields.

Abstract (sommario):

This thesis examines several nuanced issues, including equitable access, regarding long-distance intercity travel. In the United States, studies of transportation equity focus on affordable access to local destinations and basic services. The limited studies of long-distance intercity travel focus on observed demand, ignoring latent or unmet demand. Both quantitative and qualitative data are used to explore the differences between those who participate in long-distance travel and those with unmet need for it. This thesis found that the ability to participate in long-distance travel plays a role in one’s overall well-being. Undertaking long-distance trips facilitates access to opportunity for cultural and educational experiences, as well as the maintenance and creation of social capital, factors which were indicated by study participants. The first part of the thesis examines equity in access to long-distance travel between individuals by using data from a state-wide survey completed by 2,232 Vermonters for the Vermont Agency of Transportation in 2016. Five ordinal logistic regression models that approximate different levels of realized and unmet travel are used to understand how access to intercity travel differs by socioeconomic, geographic location, and household characteristics. A total of 22 percent of respondents indicated they had unmet demand at least once per year. Furthermore, there was a significant correlation between those who had unmet demand within Vermont and outside of Vermont, proxies for local and intercity travel, respectively. Income level, Internet access, and education level were found to be significant predictors of realized long-distance travel. Household size and composition, household vehicles, age, income, and self-reported urban residence were predictors of both unmet local and long-distance travel need. In addition, full-time employment was significant for local unmet need, while miles to the nearest metropolitan area was a significant predictor for longer travel needs. Models of actual travel were stronger than for unmet demand, indicating that other unmeasured predictor variables may be important, thus requiring qualitative exploration. The second part of the thesis consists of an in-depth examination using semi-structured interviews regarding intercity travel with 24 women living in Chittenden County, Vermont. In addition to the qualitative survey methods, data from a social network geography survey designed specifically for the study and an overall well-being survey were used. Interviews were coded by theme relating to travel type, barriers to travel, and impact on quality of life. A majority of participants felt long-distance travel was very important or essential to their well-being and they wished to increase the amount they did. Additionally, participants felt the need to meet with friends and family in-person, therefore necessitating long-distance travel to those who lived further away. There was also a discrepancy between the desire to meet with friends and family and how often the participants actually were able to do so. Those with higher incomes had less unmet long-distance travel need.

Abstract (sommario):

Violent crimes often result in blood-shed events associated with blood spatter. Bloodstain pattern analysis (BPA) serves as a good tool and effective approach to reconstruct the events that occur in a crime scene. Among other bloodstain patterns, impact spatter patterns are commonly found at crime scenes. An impact pattern is formed as a result of an impact force striking an exposed blood source and can be described as a radiating pattern of small individual drops. In most cases of BPA, the reconstruction of the events taken place involve investigating the blood drop flight dynamics and the mechanics of impact spatter generation to determine the origin of the impact. Thus, the discipline of Fluid Dynamics (FD) is also involved in most BPA cases. However, in the cases of multiple impact spatter generation events within a crime scene, it complicates the interpretation and analysis of the impact spatter pattern. There are many variables of blood drop flight dynamics and mechanisms of impact spatter generation in which a blood drop is exposed to and generated from. The variables of blood drop flight dynamics such as drop deformations/oscillations, breakup, diameter with respect to velocity and air/wind currents do affect a drop while in flight which may alter the trajectory curvature of a blood drop. However, it is relatively unknown in scientific literature how the variables of impact spatter generation setup such as the height of the blood source and impact force applied would affect the horizontal distance travelled by a blood drop generated from an impact spatter. Theoretically, there is also limited literature with regards to the correlation of blood drop flight dynamics to maximum horizontal distance travelled by blood drop. This literature review aims to address the effect of blood drop flight dynamics and the mechanisms of impact spatter generation setup have on the maximum horizontal distance travelled by a blood drop. The purpose of this literature review is to dictate parameters for potential research that may aid in answering the investigative question.

Abstract (sommario):

Travel Writing in Mongolia and Northern China, 1860-2020 invites readers to explore Mongolia as an important cultural space for Western travelers and their audiences over three historical eras. Travelers have framed their experiences and observations through imaginative geographies and Orientalizing discourses, fixing Mongolia as a peripheral, timeless, primitive, and parochial place. Readers can examine the travelers’ literary and rhetorical strategies as they make themselves more credible and authoritative and as they identify themselves with Mongolians and Mongolian culture or, conversely, distance themselves. In this book, readers can also approach travel writing from the perspective of women travelers, Mongolian socialist intellectuals, twenty-first-century travelers, and a Han Chinese writer, Jiang Rong, who promotes cultural harmony yet anticipates the disappearance of Mongolian culture in China.

Abstract (sommario):

AbstractThis chapter presents the development of the survey in the underlying study in this book, a description of our sample, and the results of the validation efforts. Our survey includes variations of existing scales which have been used to measure climate-relevant behaviors within the areas of housing, mobility, diet, and consumption. We go beyond these existing questions, however, as we also include various new items and analyze the validity of existing and new questions. Based on our findings we recommend a set of questions for different significant areas of emissions, for example, asking about the distance traveled by car in the previous year, the number of short-haul and long-haul flights, and a question about the frequency of the consumption of particularly energy-intensive foods.

Abstract (sommario):

AbstractTo consider green spaces and parks as valuable green infrastructure that provides various socio-ecological benefits, including health, this study analyzed changes in the use of green spaces before and during the first COVID-19 pandemic in Japan, using mobile-tracking GPS data of Kanazawa citizens. The results showed that the declaration of a state of emergency in April–May 2020 changed the outing behavior of Kanazawa citizens, and there was a strong tendency for them to avoid going out, with a decrease in the number, time, and distance of outings. On the other hand, while citizens refrained from going out, the rate of decrease in the number of visits to green spaces was smaller compared to commercial areas, and the number of walks increased slightly from 2019. The distance traveled to green spaces is generally shorter in 2020, and the number of visits to green spaces near one’s home increased in 2020. These findings suggest that those who had green spaces around their homes were able to use them for maintaining their health and refreshment during the COVID-19 pandemic, adding to the increasing evidence for the value of urban green spaces as part of nature-based solutions.

Abstract (sommario):

INDOT plans to invest nearly $100 million to build a statewide electric vehicle (EV) charging network as part of the National Electric Vehicle Infrastructure Formula Program. SPR-4509 Phase-I identified energy EV charging deserts in Indiana for long-distance trips. SPR-4509 Phase-II further examines the charging stations' impact on EV long-distance trips in Indiana. Using an agent-based simulation model, the number of charges, vehicle miles traveled, energy used during the trip, and energy used during charging were estimated for nine different cases. High EV daily charging demand areas in Indiana were shown in ArcGIS based on multiple scenarios of different charging station construction phases and EV market penetration rates. The study findings can inform the state’s EV charging plan development.

Abstract (sommario):

The paper considers the typical technical features of GPS-tracking systems and their development, as well as an analysis of existing solutions to the problem. Mathematical models for the operation of hardware and software of this complex have been created. An adaptive user interface has been developed that allows you to use this complex from a smartphone or personal computer. Methods for displaying the distance traveled by a moving object on an electronic map have been developed. Atmega162-16PU microcontroller software for GSM module and GPS receiver control has been developed. A method of data transfer from a GPS tracker to a web server has been developed. Two valid experimental samples of GPS-trackers were made and tested in uncertain conditions. The GPS-tracking software and hardware can be used to monitor the movement of moving objects that are within the coverage of GSM cellular networks.

Abstract (sommario):

This study analyzes mobility patterns during the COVID-19 pandemic for eight large Latin American cities. Indicators of mobility by socioeconomic status (SES) are generated by combining georeferenced mobile phone information with granular census data. Before the pandemic, a strong positive association between SES and mobility is documented. With the arrival of the pandemic, in most cases, a negative association between mobility and SES emerges. This new pattern is explained by a notably stronger reduction in mobility by high-SES individuals. A comparison of mobility for SES decile 1 vs decile 10 shows that, on average, the reduction is 75% larger in the case of decile 10. According to estimated lasso models, an indicator of government restrictions provides a parsimonious description of these heterogeneous responses. These estimations point to noticeable similarities in the patterns observed across cities. We also explore how the median distance traveled changed for individuals that travel at least 1 km (the intensive margin). We find that the reduction in mobility in this indicator was larger for high-SES individuals compared to low-SES individuals in six out of eight cities analyzed. The evidence is consistent with asymmetries in the feasibility of working from home and in the ability to smooth consumption under temporary income shocks.

Abstract (sommario):

Searching for missing persons is an important task for police dog teams. The purpose of this study was to investigate what proportion of missing persons are found during sector searches. The study was conducted as an exercise within the framework of the local weekly training structure (L406) for police patrol dogs in Police Region South during the winter and spring of 2022/2023. A total of 23 dog teams participated over six weeks from December 2022 to April 2023. During the searches, 25 out of 26 (96%) of the deployed decoys were found, which means that a missing person is very likely to be found by the police dog teams also during real search and rescue missions. Interestingly, the dog teams that have used a total search-time below average have found decoys to the same extent as the teams that have used more total search-time. The group that has used less than 119 minutes and where the dog has travelled an average of 9.5 km has thus been sufficient to find the missing persons. This means that the teams that have searched longer than the average and where the dog has travelled a longer distance, have used more time than actually needed. A total search-time of 119 minutes on average and a distance travelled by the dog of 9.5 km was sufficient to find all the decoys in an area of 25 hectares. A shorter search-time and shorter distance travelled would likely have been sufficient to find the same number of decoys, but based on the results of this study we cannot determine what time or distance would have been sufficient. This is however interesting to investigate further in future studies as it suggests that there is a possibility to cover larger areas in less time but with the same probability of detecting missing persons.

Abstract (sommario):

We study the allocation of dynamic electric vehicle charging investments from the policymaker’s perspective, which aims to meet statewide emission-reduction targets for the Illinois passenger vehicle sector. We determine statewide charging deployment trajectories over a 30-year planning horizon and estimate their emission reduction. Electric vehicle demand functions model the electrified vehicle market growth and capture network externalities and spatial heterogeneity. Our analysis indicates that most chargers need to be deployed in the first 10 to 15 years of the transition to allow benefits to accrue for electric vehicle drivers, availability of home charging influences consumers’ choice and drivers’ electrified travel distance, charging stations should be prioritized for frequent long-distance drivers, and spatial effects are crucial in accurately capturing the demand for electric vehicles in Illinois. We also develop a multi-criteria suitability map to site charging stations for electric vehicles based on economic, societal, and environmental justice indicators. We identify census tracts that should be prioritized during Illinois’ statewide deployment of charging infrastructure along with interstates and major highways that traverse them. Major interstates and highways I-90, I-80, I-55, and I-57 are identified as having high siting suitability scores for charging stations. Last, a novel location model was developed for equitable electric vehicle charging infrastructure placement in the Illinois interstate and major highway network. Two objectives were set to reduce detours and improve the ability to complete long-distance trips for low-income electric vehicle travelers and multi-unit dwelling residents. Our analysis indicates that if the system’s efficiency is the only consideration, low-income/multi-unit housing resident travelers are most likely to fail to complete their trips, while an equitable charging siting could mitigate this issue.

Abstract (sommario):

This Dredging Operations and Technical Support (DOTS) program technical note presents the results of a study undertaken at the request of staff from the US Army Corps of Engineers (USACE) Rock Island District (MVR) as part of a larger effort examining the potential creation of seven new permanent mooring cells along the Upper Mississippi River in proximity to lock and dam (LD) locations selected by MVR. MVR staff were interested in evaluating vessel traffic and identifying unofficial mooring areas (i.e., waiting areas) in the vicinity of LD7, LD10, LD11, LD14, LD15, LD20, and LD22; they were also interested in travel times from those unofficial mooring areas to the destination lock. The search distance for unofficial mooring areas was limited to 20 miles from the lock, or the distance to the next closest lock if less than 20 miles, in the appropriate direction (i.e., upstream or downstream), as specified by MVR staff.
