Online platforms are revolutionizing our daily lives in an attempt to make it easier by offering innovative services. They also have introduced radical new business models which provide a type of flexible working, facilitating employment. While revolutionary vehicles, they denied workers status, resulting food delivery riders facing precarious working conditions. The current regulatory framewor...

it is not known whether the instincts of wild horses have remained strong during their centuries of domestication. knowledge of this matter would give riders the opportunity to know more about the behavior of horses and consequently about safety for both horses and riders. in this current research, we studied the behavior of fifteen caspian miniature horses of different ages and sexes using sti...

The sport of bicycle motocross (BMX) was introduced as an Olympic sport in 2008. Until then, the sport was relatively unknown to the general public and has therefore been subjected to very little scientific research. The race is a one-lap event that commences when a mechanical gate falls, releasing the (maximum of) eight riders onto a course consisting of a start hill, jumps and banked turns. I...

The project aimed to investigate how hazard perception and responding is affected by level of experience as a motorcycle rider and to assess the extent to which hazard perception and responding can be improved by specific training. The literature review showed that car drivers with fewer crashes and older or more experienced drivers respond more quickly on hazard perception tasks and that at le...

• A study in real traffic with instrumented speed pedelecs (motor capacity 350 W or 500 W) Speed pedelec riders rode on average 22.5% of the distance illegally bicycle paths. Mean paths was 28.5 km/h and roadway 31.9 km/h. reduced their more than riders. On regularly hindered flow faced negative reactions. (s-pedelecs) are electric bicycles offering pedal assistance up to 45 S-pedelecs may cont...

Course holding by cyclists and moped riders includes both steering alongside a course and stabilising the vehicle. Inability to hold course may lead to conflicts with other road users. To design safe bicycle and moped facilities, and to consider the safety of those existing, knowledge about performance during course holding is necessary. Based on a literature survey, the article discusses how c...

This paper develops the model of network formation where links are used to share non-excludable public goods. In our model, we consider interactive costs and social perception of free-ride behavior. We first verify the result that public-sharing good network leads to specialization where some individuals contribute and others free ride. Second, our model features two stable pure strategy Nash e...

A mphibians may not seem the hardiest of creatures, but they have roamed Earth for 360 million years—a span including at least two major Ice Ages and four warming, interglacial periods. Yet their ability to evolve in concert with an ever-changing environment may not be enough to survive a world now dominated by human activity. Over 1,800 amphibian species, one-third of all known species, are th...
