Full textAbstract:
The National Highway Traffic Safety Administration (NHTSA) approached NASA to evaluate vehicle rollover resistance using the High Capacity Centrifuge facility. Testing was planned for six different sport utility vehicles (SUV). Previous methods for simulating rollover conditions were considered to be not indicative of the true driving conditions. A more realistic gradual application of side loading could be achieved by using a centrifuge facility. A unique load measuring lower support system was designed to measure tire loading on the inboard tires and to indicate tire liftoff. This lower support system was designed to more closely emulate actual rollover conditions. Additional design features were provided to mitigate potential safety hazards.

The purpose of this study is to analyze the dimensions of competitive strategy and strategic mapping group of vehicle manufacturers in the segment Sport Utility Vehicle. Since the government applied liberalization automotive policy in 1999, the automotive industry in Indonesia has improved significantly so that the competition increased. It can be seen from the increasing number of foreign brands that entered Indonesia’s market. National car sales continue to rise and break the number of 1.229.903 units in 2013. The segmentation of products in the automotive industry is based on the function of vehicles consisting of passenger cars, commercial cars, buses and trucks. In the segmentation passenger car, there are four sub-segmentation are sedans, multi-purpose vehicle (MPV), sport utility vehicle (SUV) and a city car. SUV type itself is currently being developed in which the number sold in October 2013 to as many as 57.446 units. As a relatively new segment, the characteristics of competition in the SUV market has not been thoroughly established as other types of vehicles. This study uses descriptive analysis to collect data from various sources so that the results of this study will provide a comprehensive overview of the dimensions of competitive strategy and strategic group mapping vehicle manufacturers Sport Utility Vehicle (SUV) in the Indonesian market.

Full textAbstract:
Since the oil crisis of the last century, drag reduction for vehicles has become the focus of researchers. Currently the world’s major car brands have to seize the sport utility vehicle market. However, the sport utility vehicle models usually have a larger frontal area which brings challenges to drag reduction. This requires a better understanding of flow around sport utility vehicle models. The Motor Industry Research Association square-back vehicle model is similar to the sport utility vehicle geometry and can reflect the typical characteristics of aerodynamics of sport utility vehicle models. In this article, the wake flow structures of a 1/8 Motor Industry Research Association model is measured by particle image velocimetry. The results indicate that there is an obviously “n” type backflow vortex behind the vehicle. In the vertical direction, the vortex rotates from the outside to the inside, meanwhile the vortex rotates from the inside to the outside in the longitudinal direction. There is a velocity deficit region between the vortex and the back of the model which is an important source of drag force. This article summarizes the results of particle image velocimetry measurements from the model tests and obtains a picture of the structures of the wake vortex finally which can provide a theoretical basis for the drag reduction research in the future.

Full textAbstract:
Sport is viewed as a setting with potential to offer social benefits to youth participants and alleviate broader social problems. Such promise requires intentionality of sport program philosophy, design, and execution. When designed with intentionality, youth sport can bring about positive change for individual youth and societies. This paper overviews the broad literature base, exploring 2 approaches to the promotion of social development through youth sport. One explores social- and/or life-skill development through sport for individual participants, whereas the other examines the role of sport in addressing broader social problems. Evidence-based strategies for fostering social development through youth sport are synthesized, providing guidance to coaches, administrators, youth workers, and others engaged in youth sport design, and exemplar programs that use youth sport as a vehicle for social development are presented. Limitations in youth sport research are summarized, and a call is made for more intentionally designed youth sport to promote social development.

Full textAbstract:
A heteroscedastic ordered logit model was used to study the effects of various vehicle, environmental, roadway, and occupant characteristics on the severity of injuries sustained by vehicle occupants, conditional on the crash occurrence. As expected, the models found that heavier vehicles increased both a vehicle's crashworthiness and driver aggressiveness toward others. The models also found that if all passenger vehicles were to become 1,000 lb heavier, crash injury outcomes would not change dramatically. However, if all passenger cars were to become light-duty trucks (i.e., minivans, pickups, and sport utility vehicles) of the same weight, incapacitating injuries and fatalities were predicted to rise by 26% and 64%, respectively. Beyond weight and vehicle type, many other factors were controlled for as well. For example, older occupants and female occupants were more likely to experience injury and death, particularly when navigating curved roadway sections with higher speed limits.

This article explores the socially constructed space of Wikipedia and how the process and structure of Wikipedia enable it to act both as a vehicle for communication between sport fans and to subtly augment existing public narratives about sport. As users create article narratives, they educate fellow fans in relevant social and sport meanings. This study analyzes two aspects of Wikipedia for sports fans, application of statistical information and connecting athletes with other sports figures and organizations, through a discourse analysis of article content and the discussion pages of ten sample athletes. These pages of retired celebrity athletes provide a means for exploring the multidirectional production processes used by the sport fan community to celebrate recorded events of sporting history in clearly delineated and verifiable ways, thus maintaining the sport fans’ community social values.

Full textAbstract:
The different characteristics of sport utility vehicles (SUVs), pickup trucks, and passenger cars put the smaller vehicle at a disadvantage in a crash. A larger difference in the speed of two vehicles can also increase crash severity, and increases in speed variability on a roadway can decrease overall safety. Research investigated whether drivers of SUVs, pickup trucks, and passenger cars choose different vehicle speeds during winter weather. Vehicle speed, roadway condition, time of day, and vehicle type were recorded during normal and winter-weather conditions. The results indicated that winter-weather vehicle speeds for all three vehicle types were significantly less than normal and that during the day a large percentage of the speed reduction occurs after snow begins to accumulate in the gutter pans of the roadway. Vehicle speed variability also increases during winter-weather conditions. The average SUV speed was statistically higher than the average passenger car speed during the day for four of the five winter-weather roadway surface conditions observed. The magnitude of the speed differences increased with roadway snowcover, but it was always less than 5.6 km/h (3.5 mph). The winter-weather speed differences between passenger cars and SUVs, although small, may have safety implications. The safety of winter-weather roadways may be lower than before the increase in SUV use, more-severe winter-weather crashes may occur between passenger cars and SUVs, more SUV run-off-the-road crashes might occur, and the safety benefits of larger vehicle characteristics may be smaller than believed.

Full textAbstract:
Participation in sport can act as a means or context for enhancing the social inclusion of migrants and refugees. Research has examined if and how mainstream sport organizations’ practices of engaging newly arrived migrants and refugees are effective in supporting participation in sustainable and culturally appropriate ways. Little is known, however, about the impact of community-driven sports events on sustainable participation by migrants and refugees. This paper examines this question with an analytical focus on community sustainability and the role of culture in sport event sustainability practices. The authors draw on ethnographic fieldwork with the Amsterdam Futsal Tournament (AFT), a sports event organized by Somali diaspora community members, to consider how event organizers and participants seek to promote cultural sustainability in a diaspora sport context. The fieldwork comprised 49 semi-structured interviews, participant observation before, during and after the event, and digital ethnography of event-related social media. The findings show the importance of cultural sustainability as a driver of community-driven sport sustainability practices, but also indicate how this driver is closely linked to addressing organizational and individual sustainability. The analysis demonstrates how the AFT can serve as a catalyst for the expansion of sport and community events among Somali diaspora communities.

Nowadays, hybrid electric vehicles represent one of the main solutions for the reduction of greenhouse gases in the automotive sector. Alongside the reduction of CO2, hybrid electric vehicles serve as a strong alternative on drivability and performance to conventional internal combustion engine-based vehicles. Vehicles exist with various missions; super sport cars usually aim to reach peak performance and to guarantee a great driving experience to the driver, but great attention must also be paid to fuel consumption. According to the vehicle mission, hybrid electric vehicles can differ in the powertrain configuration and the choice of the energy storage system. Manufacturers have recently started to work on Lithium-Ion Capacitors (LiC) -based hybrid vehicles. This paper discusses the usage of a control-oriented vehicle and powertrain model to analyze the performance of a dual motor LiC-based hybrid V12 vehicle by Automobili Lamborghini. P3–P4 and P2–P4 parallel hybrid configurations have been selected and compared since they allow to fully exploit the potential of the LiC storage system characterized by high power. The validated model has been used to develop control strategies aimed at fuel economy and CO2 reduction, and in particular, both Rule Based Strategies (RBS) and Equivalent Consumption Minimization Strategies (ECMS) are presented in the paper. A critical comparison between the various powertrain configurations is carried out, keeping into account the peculiarities of the LiC technology and evaluating the performance of the different control approaches.

Purpose Given greater awareness of environmental issues and the acceleration of climate change, universities are increasingly requiring undergraduate students to complete coursework in environmental issues. Research has shown that environmental courses hosted in science departments can be too challenging for students with no science background. Thus, new approaches to general environmental education at the undergraduate level are necessary. This paper aims to advance three transformative sustainability learning (TSL) interventions that leverage sport as the living laboratory for environmental education through examining green teams and in depth sport venue tours. Design/methodology/approach This paper details the experimental application of three TSL interventions in undergraduate sport courses. Findings Each intervention produced lasting benefits for several parties. Students benefit from greater exposure to sport management organizations and a hands-on learning opportunity. Sport organizations benefit from a promotional opportunity to showcase their sustainability efforts, improved sustainability practices at their facilities and the opportunity to leverage the students’ involvement for fan engagement initiatives Research limitations/implications The interventions presented in this paper were developed in a North American sport context, however, there is a considerable opportunity to develop similar interventions in any region where sport organizations exist. Originality/value Despite being one of the most universally appreciated and visible industries, the sport industry has yet to be used as a site for meaningful sustainability learning interventions. The interventions presented herein introduce the opportunity to leverage students’ love of sport for outcomes for all parties: the students, the host organization and sport fans.

Sport is a vehicle for social change and should be leveraged as such in 2021 and beyond to address matters of equality. In recent years, the public has paid greater attention to transgender athletes participating in sport at all levels—high school, collegiate, professional, and Olympic—despite the fact that transgender athletes have been competing in sports for decades. Backlash has arisen in general but also more specifically in response to several recent Supreme Court cases that have both solidified and extended rights of lesbian, gay, bisexual, transgender, and other gender and sexual minorities. In turn, state laws that seek to limit the rights of transgender students to participate in sports have been drafted around the country. To be sure, these laws are often built on erroneous data, a misunderstanding of facts, and ignorance, but their existence continues to fuel the public debate on whether transgender athletes should be allowed to participate based on their gender identity or their sex as determined at birth.

Full textAbstract:
Manufacturers often develop new products by modifying and extending existing products in order to achieve new market demands while minimizing development time and manufacturing costs. In this research, an efficient derivative design process was developed to efficiently adapt existing aircraft designs according to new requirements. The proposed design process was evaluated using a case study that derives an unmanned aerial vehicle design from a baseline manned 2-seatlight sport aircraft. Multiple unmanned aerial vehicle operational scenarios were analysed to define the requirements of the derivative aircraft. These included patrol, environmental monitoring, and communications relay missions. Each mission has different requirements and therefore each resulting derivative unmanned aerial vehicle design has different geometry, devices, and performance. The derivative design process involved redefining the design requirements and identifying the minimum design variable set that needed to be considered in order to efficiently adapt the baseline design. Uncertainty was considered as well to enhance the reliability of the optimized result when it considered different conditions for each mission. An optimization method based on the possibility based design optimization was proposed to handle uncertainty that arises in the design requirements for the multi-role nature of unmanned aerial vehicles. In this paper, the possibility based design optimization method was implemented with multidisciplinary design optimization technique to derive the derivative unmanned designs based on originally manned aircraft. This approach prevented constraint violation via uncertainty variations in the operating altitude and payload weight for each. The unmanned aerial vehicle derivative designs satisfying the requirements of three different missions were derived from the proposed design process.

Full textAbstract:
Vehicle classification is the process of separating vehicles according to various predefined classes. Vehicle-classification information can be used in many transportation applications, including road maintenance, emissions/pollution estimation, traffic modeling and simulation, traffic safety, and toll setting. An example of a classification scheme using the following seven vehicle classes is presented: cars, sport-utility vehicles/ pickups, vans, limousines, buses, two-axle trucks, and trucks with more than two axles. This system uses vehicle inductive signatures collected from existing loop-detector infrastructure. It also uses a heuristic-discriminant algorithm for classification and a multi-objective optimization for training the heuristic algorithm. Feature vectors obtained by processing inductive signatures are used as inputs into the classification algorithm. Three different heuristic algorithms were developed, yielding encouraging results of 81 to 91 percent overall classification rates. The results demonstrate the potential of collecting network-wide vehicle-classification data from inductive loops. The availability of vehicle-classification data helps to improve traffic surveillance and better defines dynamic traffic networks.

Full textAbstract:
This paper describes an approach for the development of prediction models for the estimation of mileage-related vehicle depreciation that can be used in the estimation of the benefits derived from transportation network improvements. The approach takes advantage of published online data for vehicle valuations. A new asymmetric logistic prediction model for total vehicle depreciation, including initial and mileage-related depreciations, is proposed and fitted to collected valuations data. The added benefit of this prediction model is that it takes into consideration both vehicle age (i.e., years since manufacture) and vehicle usage (i.e., miles of travel). Six small light-duty vehicles (SLDVs), five large light-duty vehicles (LLDVs), three two-axle trucks, one single-unit truck, and two combination trucks were considered in this study. Vehicle fuel sources included gasoline, diesel, gasoline-ethanol blend of up to 85% ethanol (E85), and hybrid-electric, resulting in 26 combinations of vehicle type and fuel source. Additionally, the developed models were adjusted to account for the effects of average speed of vehicle and roadway characteristics (e.g., grade, curvature) on vehicle depreciation. The practicality of the developed models for large sport utility vehicles (SUVs) and midsize cars was illustrated using select examples highlighting the models’ sensitivity to vehicle average speed and roadway characteristics.

Full textAbstract:
Flying activities of sport aviation vehicles normally use Internal Combustion Engines (ICE) for their powerplant, which emits Carbon Dioxide (CO2) and also produces noise. Environmental issues regarding harmful gas emission and noise may restrict the sport aviation activities and resulting in reduction of interest in flying as a sport activity. The feasible solution for this issue is by replacing the Internal Combustion Engines (ICE) with Electric Engines on all sport flying vehicles. The Modenas CTric Electric Engines was tested to measure the parameters required by comparable Internal Combustion Engine used by sport aviation flyers. Other parameters; engine endurance, temperature and performance, were also tested. The bench test was conducted using specially design test rig. The results show that there is a possibility for the Modenas CTric Motorcycles Electric Engine used as an alternate source of powerplant for paramotors and microlight aircraft. However, there is penalty on the vehicle payloads due to weight of the battery. Lighter battery technology integration is to be developed to reduce the weight of the flight vehicles. This study serves as a platform for further work in electric engine technology for commercial aircraft application. Availability of green engine (no emission and noise output) will generate more interest in sport aviation activities and prepare for the future commercial Electric Engine aircraft application.

Full textAbstract:
Road vehicles drag is a direct consequence of a large wake area generated behind. This area is created owing to the vehicle shape, which is determined by the class, functional and aesthetic of the vehicle. Aerodynamic characteristics are a ramification and not the reason for the vehicle architecture. To enhance pressure recovery in the wake region, hence reduce drag, three different passive flow control techniques were applied to sport-utility-vehicle (SUV). A three-dimensional SUV was designed in CATIA, and a numerical flow simulation was conducted using Ansys-Fluent to evaluate the aerodynamic effectiveness of the proposed flow control approaches. A closed rectangular flap as an add-on device modifies the wake vortex system topology, enhances vortex merging, and increases base pressure which leads to a drag reduction of 15.87%. The perforated roof surface layer was used to delay flow separation. The measured base pressure values indicate a higher-pressure recovery, which globally reflected in a drag reduction of 19.82%. Finally, air guided through side rams was used as steady blowing. A steady passive air jet introduced at the core of the longitudinal trailing vortices leads to a confined wake area. The net effects appear in a global increase in the base pressure values and the pronounced drag reduction of 22.67%.

Full textAbstract:
With increasing speed limits and more light trucks penetrating the market, concern over their rollover risk is growing. In particular, the general public and automobile manufacturers would like to know if the increasingly popular sport utility vehicles (SUVs) are indeed safer than other vehicle platforms. The influences of various vehicle platforms on rollovers and driver injuries were investigated. Specifically, ( a) the rollover intensities of SUVs vis-à-vis those of other vehicle types in single-vehicle crashes and ( b) the severity of the resulting driver injury were explored. Data from a good-quality federally maintained database were used for crash analysis. The database contains a relatively clean stratified sample of police-reported tow-away crashes nationwide, and it contains detailed information about vehicle rollovers. Rollover intensity, captured by the number of quarter turns, was investigated by using weighted negative binomial models; injury severity, measured on the abbreviated injury scale, was examined by using weighted ordered logit models. New insights emerged about the factors that increase rollover intensity and injury severity. As expected, SUVs are more likely to roll over and therefore injure their occupant drivers more severely. However, SUVs also protect their drivers during collisions because of their greater crashworthiness. In fact, the SUV crashworthiness effect exceeds the rollover effect, on average. The implications of these findings are discussed.

Mental health is one of the most prominent global burdens of disease among young people, while organized youth sport is one of the most popular activities for children and adolescents worldwide. Organized sport can be an engaging vehicle for the promotion of mental health, but participation also brings several meaningful risks and detriments for young people’s mental health. This paper contains a review of the evidence underpinning the relationships between sport participation and mental health during childhood and adolescence and also outlines the key areas of risk for mental health problems. Relevant theoretical frameworks are discussed, as are the key concepts underpinning 2 exemplar sport-based interventions to promote mental health and reduce the risk of mental health problems. Recommendations for best practice in organized youth sport are not available. However, relevant frameworks are outlined, from which administrators, coaches, and athletes can base the design and delivery of sport programs to be consistent with relevant theoretical and philosophical approaches such as the athlete-centered approach to youth sports.

Full textAbstract:
The progress in pedestrian safety enhancement is the result of multi-stage work, which is based mainly on the vehicle enhancement and appropriate traffic organization. However, the full separation of vehicle traffic and pedestrians seem to be impossible nowadays. The paper presents a new method for assessing the influence of vehicle structural components on pedestrian kinematics. An integral part of the method is the relationship, named as the k parameter, which can determinate the geometric property of the pedestrian body movement (kinematics) after a collision. The development of the new algorithm is the answer to the problem of assessing the risk posed by the impact of the vehicle with a high bumper/bonnet reference line (e.g. a Sport Utility Vehicle – SUV) on a pedestrian. The presented method can be a useful engineering tool to assess the safety of vehicles, both brand-new and used. The developed test system binds together a new defined kinematic criterion as well as the existing biomechanical criteria (the assessment of vehicles using pedestrian impactors). The presented method was verified on a compact vehicle and a SUV.

The purpose of this study was twofold: (a) to explore the body image of athletes with physical disabilities, and (b) to understand how sport influences body image among these athletes. We interviewed 20 male and female athletes (Mage = 34.25, SD = 8.49) from a variety of sports regarding their body image and the role of sport in influencing body image. A thematic analysis (Braun & Clarke, 2006) was used to generate six themes: (a) personal significance of injury and disability, (b) noncentrality of the body and disability, (c) positive influence of sport on body esteem, (d) social factors influencing body-related emotions and perceptions, (e) body critiques and preferences, and (f) positive thoughts and emotions about the body. Sport seemed to be an important vehicle for experiencing body-related pride, and athletes expressed an intimate connection with the body parts that enabled them to physically compete.

The need for parking space in the land use system for educational activities is needed in line with the growth of vehicle users. Educational areas with a high center of activity really need adequate parking space for ease of accessibility. The center of sports activities in the area of higher education activities requires the ease of using vehicle parking. The system of sports activities in higher education areas with high movement activities requires evaluation of parking space requirements in accordance with the activity system. Analyzing parking space requirements based on system activities is the main objective of this study. Specifically the purpose of the study is based on the analysis of parking duration. The frequency and accumulation of vehicles in the parking area is a characteristic impact of the activity system of sports activities. The analysis method based on parking space units is analyzed based on parking methods with variables that affect vehicle use in the activity system in the sports activity zone. Variables of parking user characteristics are based on survey responses from vehicle users from their activity system. The results showed the existing conditions with 34 units of parking spaces with parking index 1.1764 with the need for parking space of 460 m2. With a system of high activity and vehicle growth, the parking area needs at the prediction of the next 10 years require an area of 59 parking spaces with a parking index of 0.949 with a parking area of 643.89 m2. So that the development of the parking area in the sports zone activity system requires an additional parking area of 183, 89 m2.

Full textAbstract:
To determine the major event pathways that result in sport utility vehicle (SUV) rollover, researchers at the University of Michigan Transportation Research Institute examined SUV rollover cases selected from the National Automotive Sampling System crashworthiness data system files for 1999 to 2001. Selected SUVs included the Ford Explorer, Jeep Cherokee, Chevrolet Blazer, Toyota 4-Runner, and GMC Jimmy for model years 1989 to 2001. Researchers coded up to six pre-rollover events, along with the stability of the vehicle (tracking or skidding) after each event. In addition, crash avoidance and recovery maneuvers were recorded, along with the rollover initiation type, location of rollover initiation, direction of roll, number of quarter turns of roll, location of roll, and surface condition at rollover initiation. Approximately 34% of SUV rollovers began with a loss of control caused by tire saturation, and about 75% of the loss-of-control cases were on icy, wet, or snowy roads. Of the SUVs that ran off the road as the first event, 47% returned to the road before rolling over, and of these, 76% were tracking (presumed under control) before initial road departure. Between 40% and 49% of SUV rollover crashes experienced yaw instability while still on the roadway before roll. These rollovers may be addressed by electronic stability control devices if such devices can increase the control limits of the vehicle.

Full textAbstract:
Older drivers are a growing and particularly vulnerable population. Advances in vehicle safety may reduce the risk of death in the event of a motor vehicle crash (MVC). Although previous studies have identified a relationship between increasing model years and decreased risk of death in MVC among adult drivers, this relationship has not been quantified among older drivers. The purpose of this study was to examine the relationship between vehicle model year and the risk of death among drivers aged 65 years and older who were involved in MVCs in the United States from 2010 to 2015. Data were from a census of all fatal MVCs and a representative sample of all police-reported crashes nationwide. Drivers were stratified into five age groups (65–69, 70–74, 75–79, 80–84, and 85+). Vehicles examined were cars, sport utility vehicles, pick-up trucks, and vans. Overall, older drivers driving vehicles older than model year 1990 were more than twice as likely to be killed in a crash as individuals driving vehicles of model years 2000 to 2009. Older drivers driving vehicles of model years 2010 and newer had 46% lower risk of MVC death than those driving vehicles of model year 2000 to 2009. The relationship between vehicle model year and risk of death in a crash varied by driver age and vehicle type, however, the same overall patterns were observed for all age groups and vehicle types examined. These findings suggest that older adults are responsive to improvements in vehicle safety.

Full textAbstract:
Many scholars have attempted to apply various theories in the field of sport (Bordieu, 1984 & Brainer 2007). This particular area looks at the relationship between Marxism to the sociology of sport and how it has influenced societal structures as well as the impact it has had on the economy. Though these theories are useful on exploring the general nature of sport, questions may be raised on have they influenced the way sports is managed today also? It is widely accepted that management theories have been influenced by industry and that many scholars have used Marxism and feminist approaches to form some sort of construct of this. However does one or two apply to all? And are they appropriate to areas such as the service industry that sport falls in too? This paper attempts to look at how Marxism may have had some influence on sports management through capitalists, masculinity and power and the weld it has had on females developing in such a field because of its deeply held roots. And more importantly possibly oppressed feminism in this field. There are also arguments made because of such oppression by the male domination that they have used sports as a vehicle to segregate society and influence the direction of sports management. Therefore the discussion in its true entirety at most is a snapshot of how one theory dominates the area of sports management and how it impinges on others both on their application and development.

In contrast to the popular policy claim that sport might serve as vehicle to meet the Millennium Development Goals, empirical evidence based on large-scale survey data is largely missing. We use panel data based on a cohort of children and employ propensity score matching to identify the effects of sports participation on child development in Peru. Our findings suggest that participation in a sports group has positive impacts on subjective health and a measure of social capital. However, and in contrast to developed countries, we find no statistically significant effects on well-being and human capital formation.

E-Sport in South Korea has become one of the country's big income. E-Sport has a considerable influence on the country. Therefore E-Sport is questionable from local to international. The facilities needed for E-Sport also really need to be related to training places for people who want to become E-Sports athletes in order to be able to participate in international competitions. In some developed countries, the video game again recommends a vehicle to spend free time being asked to be a profession with income that is quite convincing. This profession is an Athlete professional in this case who is an expert in playing video games or who has been widely known as e-Athlete. If you have been given the title of the athlete, things that must be categorized in sports are given the name E-Sport. In Indonesia itself, with the recognition that the Indonesia E-Sport Association (IeSPA) as an organization that respects Kemenpora is also a bright spot for the development of sports in our country. Although E-Sport shows don't seem difficult to do just because a computer with high specifications is needed, however, it is necessary to implement it requiring a place with a certain arrangement of spaces. So that athletes who will compete can simplify the game. Therefore a place that is specifically designed to carry out E-Sport events is needed.AbstrakE-Sport seperti di Korea Selatan menjadi salah satu pendapatan yang cukup besar bagi negara itu. E-Sport memiliki dampak yang cukup besar bagi sebuah negara. Karenanya E-Sport dipertandingkan dari lokal sampai ke internasional. Kebutuhan sarana untuk E-Sport juga sangat perlu apalagi dengan adanya tempat pelatihan bagi masyarakat yang ingin menjadi atlet E-Sport sehingga dapat mengikuti kompetisi di dunia Internasional. Di beberapa negara maju video game bukanlah lagi sebuah wahana untuk menghabiskan waktu luang melainkan menjadi sebuah profesi dengan pendapatan yang cukup meyakinkan. Profesi tersebut dengan adalah menjadi atlit professional dalam kasus ini yang ahli dalam bermain video game atau yang sudah banyak dikenal orang dengan sebutan e-Atlit. Di Indonesia sendiri, dengan diakuinya Indonesia E-Sport Association (IeSPA) sebagai organisasi yang diakui Kemenpora turut menjadi titik terang perkembangan olahraga ini di negeri kita. Untuk bangunan E-Sport di Indonesia sudah ada sejak dulu karenanya dalam perancangan akan memakai metode preseden untuk mengambil apa aja yang menjadi sebuah ciri bangunan E-Sport. Keberadaan bangunan E-Sport di Jakarta banyak terletak di Jakarta Barat terutama kawasan Palmerah, jadinya lokasi tapak diperkirakan berada di Palmerah.

Full textAbstract:
While it is clear from a small body of scholarly literature that sport and physical activity play important roles in the daily lives of many inmates in diverse prison contexts around the world, there remains relatively little research that sociologically explores the significance of these physical practices in correctional environments. This paper helps to address this gap by examining one of the key tensions in prison sport: its deployment by corrections policymakers and administrators as a form of social control and its simultaneous use by prisoners as a vehicle for resistance and subversion. Situating the research in Goffman’s concept of the total institution, the paper explores how prisoners, though stripped of many resources for self presentation and collective subversion, refashion sport activities, materials, and spaces to their own purposes – and, in doing so, how they resist, in a limited fashion, the prison’s social control aims. More broadly, these findings point to the potential social significance of sport and physical activity as vehicles for the limited expression of agency in situations of extreme deprivation or imposing disciplinary regimes.

Full textAbstract:
Although research has widely investigated labels across a range of product domains, one understudied area is the use of absolute versus relative rating approaches to information provision. For example, under an absolute rating approach to vehicle ecolabels, the consumer is informed of the actual amount of fuel consumed during use of a vehicle compared with that of all other vehicles on the market. Under a relative rating approach, the fuel consumption is communicated in relative terms, comparing the vehicle only with others in the same class. The current research illustrates that switching from an absolute to a relative rating approach can lead to a reversal effect in the perception of a car's environmental friendliness. For example, a sport-utility vehicle can be perceived as either environmentally friendly or not, depending on the type of rating approach used. The authors demonstrate that visual representation drives this effect, using a colored alphabetical rating scale to communicate environmental performance.

The Internet website has become an effective marketing vehicle for sport organizations. The purpose of this study was to examine theoretical relationships between key variables of online sport consumption behavior such as sport consumers’ perceptions of sport website quality, satisfaction, and behavioral loyalty to the websites. In addition, the mediating effect of e-satisfaction between website quality and e-loyalty was examined. The results of data analyses using structural equation model tests revealed that loyalty to a sport team’s website was more likely to occur as sport fans developed positive perceptions and satisfaction with the website. The results also suggested that consumer e-satisfaction is an important mediating variable between sport website quality and e-loyalty.

Full textAbstract:
To explore the relationship between fuel consumption and speed for a vehicle on a superhighway with a design speed exceeding 120 km/h, the fuel consumption data provided by the Test of Easy Car platform are used to fit the fuel consumption of different models. The fitting results show that the fitting degree of fuel consumption by a cubic curve is the highest, and the correlation coefficient is above 0.95. A fuel consumption cubic curve model of different vehicle types is established by using the fitting parameters to predict the fuel consumption when a vehicle is running at a speed of 130 km/h–180 km/h. The prediction results show that the average fuel consumption of compact vehicles is the lowest when a vehicle is running on a superhighway at speeds of 130 km/h–180 km/h, with values of 8.95 L/100 km–16.26 L/100 km; the average fuel consumption of sport utility vehicles (SUVs) is the highest, with values of 12.65 L/100 km–22.70 L/100 km. The prediction results can be used to estimate the cost of using a superhighway and provide a basis for estimating the feasibility of superhighways.

Full textAbstract:
Vehicles equipped with in-wheel motors (IWMs) feature advanced control functions that allow for enhanced vehicle dynamics and stability. However, these improvements occur to the detriment of ride comfort due to the increased unsprung mass. This study investigates the driving comfort enhancement in electric vehicles that can be achieved through blended control of IWMs and active suspensions (ASs). The term “ride blending”, coined in a previous authors’ work and herein retained, is proposed by analogy with the brake blending to identify the blended action of IWMs and ASs. In the present work, the superior performance of the ride blending control is demonstrated against several driving manoeuvres typically used for the evaluation of the ride quality. The effectiveness of the proposed ride blending control is confirmed by the improved key performance indexes associated with driving comfort and active safety. The simulation results refer to the comparison of the conventional sport utility vehicle (SUV) equipped with a passive suspension system and its electric version provided with ride blending control. The simulation analysis is conducted with an experimentally validated vehicle model in CarMaker® and MATLAB/Simulink co-simulation environment including high-fidelity vehicle subsystems models.

To establish accurate models for powertrain optimization of a Chinese sport utility vehicle Landwind X8, a powerful CAE tool GT-Drive was used to evaluate the vehicle drivability and fuel economy. Various proper models were established and vehicle performance was simulated, obtained results show that drivability of the vehicle is satisfactory in a macro sense, but fuel economy is moderate. Further comparison of simulated performance indices with field test data demonstrates that nearly 80% of the absolute relative errors are below 5%, the maximum absolute relative error is also less than 10%. Thus, the simulated data met well with the test data, it is confirmed that the established simulation models are validated and can be used as effective analysis tools in further powertrain optimization.

Full textAbstract:
Light truck vehicles (LTVs), including light-duty trucks, vans, minivans, and sport-utility vehicles, are generally larger than common passenger cars and are able to take on additional tasks. LTVs usually ride higher than other common passenger cars, which likely affects the visibility of passenger car drivers. The role of LTVs in rear-end crashes was investigated. The use of statistical models of unordered multiple categories was attempted, including multinomial logit (MNL), heteroscedastic extreme value (HEV), and bivariate probit (BVP) models. Four different rear-end crash configurations (lead and following vehicles) were defined on the basis of the type of the two vehicles involved (LTV or regular passenger car). General Estimates System (GES 2000) traffic crash data were used to calibrate the three suggested models (the MNL, HEV, and BVP models). Modeling results showed that there are sight distance and discomfort problems when a driver in a regular passenger car is driving behind an LTV. The probability of a rear-end crash involving a regular passenger car striking an LTV increases when the driver of the following vehicle is distracted. The analysis also illustrates that the probability of a regular car striking an LTV increases when the driver of the following vehicle has an obscured view.

In this article, We explore the extent to which political cartoons and comic strips – as mediated public and political visual art, the ‘ninth art’ according to Groensteen’s The System of Comics (2007[1999] – subvert/confirm institutional values of so-called Western democracies during times of war. Our concern, as sociologists of sport, is with the ways dominant sporting sensibilities are (re)presented in cartoon art, and how sport itself is conflated with patriotic ideologies of war as a vehicle for propaganda. In particular, We interrogate how competitive-sporting ideals are aligned with war and conflict, and mobilized by cartoons during periods of Western-asserted conflict. We are intrigued by how some cartoon illustrations have the visual power to misplace, simplify and essentialize – via sporting analogy – the intense and complex emotions surrounding war. The aim of the article is to examine how the visual within popular culture is used to dis-connect and dis-engage a public with the realities of war and human conflict.

In this introduction to a special issue on sport communication and social justice, we offer some reflections on the state of the discipline as it relates to social justice. We bring attention to the role of sport communication scholars in the advancement of social justice goals and articulate a set of dispositions for researchers to bring to their practice, predicated on internalizing and centralizing morality, ethics, and the political. Identifying the epistemological (under)currents in the meaningful study of communication and sport, we offer a set of challenges for researchers in the contemporary critique of the communication industries based on “sensibilities” or dispositions of the research to those studied. We then introduce and frame the 13 articles that make up this double special issue of Communication & Sport. Collectively, these articles begin to demonstrate such dispositions in their interrogation of some of the most important and spectacularized acts of social justice campaigns and activism in recent decades alongside investigations of everyday forms of marginalization, resistance, and collective action that underpin social change—both progressive and regressive. We hope this special issue provides a vehicle for continued work in the area of sports communication and social justice.

This exploratory study examines the potential of intercollegiate sport participation to empower women at the group and societal levels. Telephone interviews were conducted with 24 women athletes from various sport teams at three Division I universities. Findings demonstrate that at the group level, sport facilitates female bonding and the development of a group identity and common goals. Empowerment at the societal level was noted when athletes indicated that their participation in sport challenged societal perceptions of women as well as making them more aware of gender inequalities in sport. However, the sport context did not appear to be an effective vehicle in enhancing athletes’ consciousness as women or encouraging their activism in support of women’s issues.

Full textAbstract:
Although sport historically represents an important vehicle for the dissemination of values and principles, it is often an arena of discrimination, most all based on gender (Balbo, 2001).
The paper is aimed at analyzing the issue of the participation of transgender women in female sports in order to identify which are the main discrimination factors. To achieve this goal, the article analyzes the online conversations on the House Bill 2706 of Arizona that proposes that transgender female student athletes should not take part in female sporting activities, as they have physiological benefits that would make unequal the sport competitions. In particular, the paper studies the contents about this issue hosted on Twitter, the popular real-time microblogging social network. The method is based on design data mining analysis, supported by the use of software for quantitative analysis of the content. The study considers Tweets published during the period between February and March 2020. Sentiment analysis of Tweets shows that the road to the complete acceptance of the female transgender universe in sport is still very long and difficult to follow.
