Currently beer is booming, mainly due to the steady rise of craft breweries worldwide. Previous surveys for occurrence of mycotoxins in beer, were mainly focussed on industrial produced beer. The present survey reports the presence of mycotoxins in craft beer and how this compares to industrial produced beer. More than 1000 beers were collected from 47 countries, of which 60% were craft beers. ...

Juvenile offenders with substance use problems are at high risk for deleterious long-term outcomes. This study evaluated the capacity of a promising vocational and employment training program in the building sector (i.e., Community Restitution Apprenticeship-Focused Training, CRAFT) to mitigate such outcomes through enhanced employment and education. Participants were 97 high-risk juvenile offe...

writing is a skill many feel they lack, the question ‘How’s your writing?’ gets at one of the dark hearts of imposter syndrome among medical education researchers. And, let’s be frank, a lot of our scientific writing is terrible: dry, chalky, convoluted stuff that even an engaged reader struggles to choke down. We find ourselves in a troubling situation: one of our valued practices—writing—is h...

Jet skiing is a rapidly growing sport. The craft incorporate safety features and the manufacturers issue detailed safety instructions. Racing is conducted with adequate attention to clothing, safety and insurance. However, casual use is widespread and is sometimes irresponsible. Serious injuries to riders are uncommon: dental and knee injuries are described. A case of renal contusion and a head...

Brewing has a long history in this country—first making an appearance in 1620 with the landing of the Pilgrims at Plymouth Rock in Massachusetts. Today, beers can be easily categorized into one of two types: 1) industrial, and 2) craft. The focus of this paper is on this second type, the "craft beer" and the so-called "renaissance" it experienced during the 1980s. In 1983, there were only 43 op...

The shocks and impacts encountered on small high-speed craft exceed the limits set for safe working practice according to current standards. European legislation regarding the exposure to vibration will have far reaching effects on the operators of such craft with respect to the safety of their employees. This paper sets out to highlight the vibration dose values that can be expected during typ...
