LECANORA BARKMANEANAA NEW NITROPHILOUS SOREDIATE CORTICOLOUS LICHEN FROM THE NETHERLANDS

Lecanora barkmaneana, a sorediate corticolous lichen belonging to theLecanora subfuscagroup, is described as a species new to science on the basis of numerous sterile collections. It is known so far as only from the Netherlands, where it often grows on roadside trees. it seems to be spreading rapidly at nutrient-rich sites.     

ATTITUDES TOWARDS EUTHANASIA AND ASSISTED SUICIDE: A COMPARISON BETWEEN PSYCHIATRISTS AND OTHER PHYSICIANS

Euthanasia and physician assisted‐suicide are terms used to describe the process in which a doctor of a sick or disabled individual engages in an activity which directly or indirectly leads to their death. This behavior is engaged by the healthcare provider based on their humanistic desire to end suffering and pain. The psychiatrist's involvement may be requested in several distinct situations including evaluation of patient capacity when an appeal for euthanasia is requested on grounds of terminal somatic illness or when the patient is requesting euthanasia due to mental suffering. We compare attitudes of 49 psychiatrists towards euthanasia and assisted suicide with a group of 54 other physicians by means of a questionnaire describing different patients, who either requested physician‐assisted suicide or in whom euthanasia as a treatment option was considered, followed by a set of questions relating to euthanasia implementation. When controlled for religious practice, psychiatrists expressed more conservative views regarding euthanasia than did physicians from other medical specialties. Similarly female physicians and orthodox physicians indicated more conservative views. Differences may be due to factors inherent in subspecialty education. We suggest that in light of the unique complexity and context of patient euthanasia requests, based on their training and professional expertise psychiatrists are well suited to take a prominent role in evaluating such requests to die and making a decision as to the relative importance of competing variables.     

A ROLE FOR THE PHYSICIAN IN CIVIL DEFENSE

Recognition of the possibility of nuclear attack upon the U. S. imposes on the American physician the obligation of preparing to deal with its consequences. The responsibility has been accepted but every physician must continue his effort to increase our medical capabilities.Organization and planning at all levels must continue and it is most essential that physicians participate in the education of the public. The A.M.A. through its Committee on Disaster Medical Care has played an active role in the development of civilian training courses and medical planning for disaster in this country.     

ON THE PARADIGM OF ALTRUISTIC SUICIDE IN THE UNICELLULAR WORLD

Altruistic suicide is best known in the context of programmed cell death (PCD) in multicellular individuals, which is understood as an adaptive process that contributes to the development and functionality of the organism. After the realization that PCD‐like processes can also be induced in single‐celled lineages, the paradigm of altruistic cell death has been extended to include these active cell death processes in unicellular organisms. Here, we critically evaluate the current conceptual framework and the experimental data used to support the notion of altruistic suicide in unicellular lineages, and propose new perspectives. We argue that importing the paradigm of altruistic cell death from multicellular organisms to explain active death in unicellular lineages has the potential to limit the types of questions we ask, thus biasing our understanding of the nature, origin, and maintenance of this trait. We also emphasize the need to distinguish between the benefits and the adaptive role of a trait. Lastly, we provide an alternative framework that allows for the possibility that active death in single‐celled organisms is a maladaptive trait maintained as a byproduct of selection on pro‐survival functions, but that could—under conditions in which kin/group selection can act—be co‐opted into an altruistic trait.
