“…This is similar to our two studies where the number and proportion of sleep-related fatal accidents were much higher in the summertime (Radun and Radun, 2006;Summala et al, 2003). Our recent survey data indicated a similar trend in self-reported cases of falling asleep while driving (Radun and Radun, 2008).…”

“…Another estimation based on the same data gives an upper estimate of 30% with alcohol-intoxicated drivers included (Partinen, 2004). Furthermore, our recent survey on a representative sample of Finnish driving population shows that 19.5% of the surveyed drivers had fallen asleep while driving at some point during their driving career, while 15.9% reported being close to falling asleep or having difficulties staying awake while driving during the last 12 months (Radun and Radun, 2006). In all of these studies young male drivers were identified as especially risky group.…”

“…For example, Langlois et al (1985) reported a seasonal pattern in fatigue-related single-vehicle accidents in Texas, with the highest number in May and July and the lowest number in January and February. The reasons behind this seasonality are still to be discovered; we proposed an explanation in relation to different driving and lifestyle habits between seasons, including sleep quality and age effects (Radun and Radun, 2006).…”

“…Attention should be paid also to the potential role of climate and latitude as possible synchronizers or sources of masking effects, especially in the conduct of chronoepidemiological and seasonality studies (Arendt, 2006;Higuchi et al, 2007;Mbanu et al, 2007;Radun & Radun, 2006;Shah et al, 2006). Papers entailing shift-work research must also clearly define the work schedule and duties of the workers (e.g., Camerino et al, 2008;Eriksen et al, 2006;Jay et al, 2006;Lammers-van der Holst et al, 2006;Persson et al, 2006;Thorne et al, 2008).…”

The main objectives of this article are to update the ethical standards for the conduct of human and animal biological rhythm research and recommend essential elements for quality chronobiological research information, which should be especially useful for new investigators of the rhythms of life. A secondary objective is to provide for those with an interest in the results of chronobiology investigations, but who might be unfamiliar with the field, an introduction to the basic methods and standards of biological rhythm research and time series data analysis. The journal and its editors endorse compliance of all investigators to the principles of the Declaration of Helsinki of the World Medical Association, which relate to the conduct of ethical research on human beings, and the Guide for the Care and Use of Laboratory Animals of the Institute for Laboratory Animal Research of the National Research Council, which relate to the conduct of ethical research on laboratory and other animals. The editors and the readers of the journal expect the authors of submitted manuscripts to have adhered to the ethical standards dictated by local, national, and international laws and regulations in the conduct of investigations and to be unbiased and accurate in reporting never-before-published research findings. Authors of scientific papers are required to disclose all potential conflicts of interest, particularly when the research is funded in part or in full by the medical and pharmaceutical industry, when the authors are stock-holders of the company that manufactures or markets the products under study, or when the authors are a recent or current paid consultant to the involved company. It is the responsibility of the authors of submitted manuscripts to clearly present sufficient detail about the synchronizer schedule of the studied subjects (i.e., the sleep-wake schedule, ambient light-dark cycle, intensity and spectrum of ambient light exposure, seasons when the research was conducted, shift schedule in studies involving shift work, and menstrual cycle stage in studies involving young women). Rhythm analysis of time series data should be performed with the perspective that rhythms of different periods might be superimposed upon the observed temporal pattern of interest. A variety of different and complementary statistical procedures can be used for rhythm detection. Fitting a mathematical model to the time series data provides a better and more objective analysis of time series data than simple data inspection and narrative description, and if rhythmicity is documented by objective methods, its characterization is required by relevant parameters such as the rhythm's period (tau), MESOR (time series average), amplitude (range of temporal variation), acrophase (time of peak value), and bathyphase (time of trough value). However, the assumptions underlying the time series modeling must be satisfied and applicable in each case, especially the assumption of sinusoidality in the case of cosinor analysis, before it can be accepted...

“…It is unlikely that a police officer would fall asleep at the wheel without his or her colleague noticing inconsistent driving or other behavior beforehand. It is worth noting that in many cases drivers who fall asleep at the wheel are either alone in the car, or their accompanying passengers are asleep 16) . In any case, fatigue and sleepiness can significantly increase the risk of losing concentration, failing to anticipate situations, and making wrong decisions 17,18) .…”

Night Work, Fatigued Driving and Traffic Law: The Case of Police Officers

Given the well-known difficulties in defining and detecting fatigue, it is a real challenge to incorporate it into either traffic or criminal law. Finnish traffic law forbids fatigued driving "only" on a general level concerning the driver's fitness to drive. We present several comments from Finnish traffic and local police officers regarding their own experiences of driving while fatigued. The comments were extracted from a larger survey of traffic (N=129) and local (N=100) police officers, and prosecutors (N=96). Although the main topic of the survey was the application of the law that forbids fatigued driving, some police officers raised the issue of their own behavior in this respect. We argue that many shift workers, including police officers, break the law, especially when driving home after a night shift.
