In phylogenetics, a plesiomorphy ("near form") and symplesiomorphy are synonyms for an ancestral character shared by all members of a clade, which does not distinguish the clade from other clades. Plesiomorphy, symplesiomorphy, apomorphy, and synapomorphy all mean a trait shared between species because they share an ancestral species.
Nursing ethics is a branch of applied ethics that concerns itself with activities in the field of nursing. Nursing ethics shares many principles with medical ethics, such as beneficence, non-maleficence, and respect for autonomy. It can be distinguished by its emphasis on relationships, human dignity and collaborative care.
Ethical Attitudes and knowledge derived from an ethical framework, including an awareness of moral questions and choices. Aesthetic Awareness of the immediate situation, seated in immediate practical action; including awareness of the patient and their circumstances as uniquely individual, and of the combined wholeness of the situation.
Like medical ethics, nursing ethics is very narrow in its focus, especially when compared to the expansive field of bioethics. For the most part, "nursing ethics can be defined as having a two-pronged meaning," whereby it is "the examination of all kinds of ethical and bioethical issues from the perspective of nursing theory and practice."
Symplesiomorphy – an ancestral trait shared by two or more taxa. Plesiomorphy – a symplesiomorphy discussed in reference to a more derived state. Pseudoplesiomorphy – a trait that cannot be identified as either a plesiomorphy or an apomorphy that is a reversal. [15]
Hennig coined the key terms synapomorphy, symplesiomorphy, and paraphyly. He also asserted, in his "auxiliary principle", that "the presence of apomorphous characters in different species 'is always reason for suspecting kinship [i.e., that species belong to a monophyletic group], and that their origin by convergence should not be presumed a ...
Primary care ethics is not a discipline; it is a notional field of study which is simultaneously an aspect of primary health care and applied ethics. De Zulueta argues that primary care ethics has ‘a definitive place on the ‘ bioethics map’ , represented by a substantial body of empirical research, literary texts and critical discourse (2 ...
Since cold-bloodedness is a plesiomorphy, inherited from the common ancestor of traditional reptiles and birds, and thus a symplesiomorphy of turtles, snakes and crocodiles (among others), it does not mean that turtles, snakes and crocodiles form a clade that excludes the birds. An apomorphy ("separate form") or derived state is an innovation.
