visual monitoring of key deep sea megafauna with an internet operated crawler as a tool for ecological status assessment
Progress in Oceanography, 2020Co-Authors: Damianos Chatzievangelou, Jacopo Aguzzi, Andrea S Ogston, Alejandro Suarez, Laurenz ThomsenAbstract:Abstract The spatio-temporal distribution of seven abundant morphospecies (i.e. taxa identified based on morphological traits) and the diversity of the benthic megafaunal community at the Barkley Canyon hydrates site (870 m, Vancouver Island, BC, Canada) were assessed in 18 linear imaging transects (each transect ~30 m long), conducted with an Internet Operated Deep-sea Crawler in November 2016. Faunal counts (as proxy for local abundances) were treated as Poisson-behaving variables and were modeled and correlated to habitat quality (i.e. level of physical seafloor disturbance, as previously induced by the crawler), fluctuating oceanographic conditions (i.e. tides and currents, seasonal transitions and episodic particle fluxes) and temporally and spatially varying food availability (i.e. elevated chlorophyll levels, proximity to the hydrate mounds as additional energy sources). The model outcome was used to establish a potential trigger-Notification Procedure for substrate disturbance monitoring when ratios of faunal abundances exceed the expected range for any morphospecies. Finally, a quality assessment of the crawler’s performance as a multidisciplinary monitoring platform was performed using individual and morphospecies accumulation curves, which aids in optimizing and standardizing data collection protocols. We showed that the abundances and diversity of hydrates megafaunal community differed in relation to physical seafloor disturbance, proximity to the hydrate mounds and episodic food input, at varying degrees. Our work sets a solid base for the future real-time, long-term monitoring of ecosystem functioning and health status in deep-sea areas exposed to industrial substrate alterations (i.e. mining, fisheries, etc.).

empirical research on euthanasia and other medical end of life decisions and the euthanasia Notification Procedure
2002Co-Authors: Gerrit Van Der Wal, Paul J. Van Der MaasAbstract:In the Netherlands, the practice of life-termination by physicians is still subject to the penal code and yet, since the seventies euthanasia and physician assisted death are continuing to occur more openly; this development is supported by public opinion, the majority of doctors, and in jurisprudence. Requirements for prudent practice have been compiled in jurisprudence and by the medical profession and, in general, a physician will not be prosecuted if he adheres to these requirements. Moreover, most hospitals and nursing homes have a written policy concerning euthanasia and physician assisted suicide. In the nineties, a considerable amount of empirical research has taken place in the Netherlands into the practice of physician assisted death. During the period 1990–1991, a research project commissioned by the Remmelink Committee studied the incidence of euthanasia and other medical end-of-life decisions. At the time, the results of this research attracted much national and international attention, also due to the fact that it was the first time that a total overview was obtained of the extent and nature of medical end-of-life decisions in any country. Other studies were carried out among large numbers of general practitioners and nursing home physicians. Various national and international publications were mostly based on these studies. Also a number of qualitative research projects have to be mentioned.

The role of the medical examiner in the euthanasia Notification Procedure in The Netherlands.
Medicine science and the law, 2000Co-Authors: J.m. Cuperus-bosma, Gerrit Van Der Wal, Piet J. Kostense, Paul J. Van Der MaasAbstract:The objective of the study was to provide an insight into the role of the medical examiner in the euthanasia Notification Procedure in The Netherlands. At the beginning of 1996 a representative group of 116 medical examiners was interviewed. The study found that there was a considerable variation in the way in which the medical examiners fulfilled their tasks. In all cases, after the physician-assisted death had taken place, the medical examiner investigated whether the attending physician had met the requirements for prudent practice, and in approximately 75% of the cases he reported his findings to the Public Prosecutor. In 78% of cases the attending physician was well known to the medical examiners, who were general practitioners, and in a third of the cases this influenced their assessment. Seventy-six per cent of the medical examiners, 61% of the members of the public prosecution and 47% of the physicians thought that it is the task to the medical examiner to review whether the requirements for prudent practice have been met by the attending physician. In conclusion further specification of the task of the medical examiner would appear to be beneficial to increase uniformity in the Procedure. In particular, it should be determined whether it is the medical examiner's responsibility to review whether the requirements for prudent practice have been met. It should also be taken into consideration whether the position of the general practitioner medical examiner is sufficiently independent to make an objective report.

evaluation of the Notification Procedure for physician assisted death in the netherlands
The New England Journal of Medicine, 1996Co-Authors: Gerrit Van Der Wal, Paul J. Van Der Maas, Jacqueline Bosma, Bregje D Onwuteakaphilipsen, Dick L Willems, F Haverkate, Piet J. KostenseAbstract:Background In the Netherlands, a Notification Procedure for physician-assisted death has been in use since 1991. It requires doctors to report each case to the coroner, who in turn notifies the public prosecutor. Ultimately, the Assembly of Prosecutors General decides whether to prosecute. Although physician-assisted death remains technically illegal, doctors are extremely unlikely to be prosecuted if they comply with the requirements for accepted practice. In 1995, the ministers of health and justice commissioned an evaluation to determine the adequacy of the Notification Procedure. Methods A random sample of 405 physicians were interviewed. We also interviewed 147 physicians who had reported cases of physician-assisted death and 116 coroners, and we reviewed 353 judicial files of reported cases. In addition, we interviewed 48 public prosecutors and reviewed the minutes of the Assembly of Prosecutors General for 1991 to 1995 and all published court decisions from 1981 through 1995.
