Phenotypic plasticity can influence evolutionary change in a lineage, ranging from facilitation of population persistence in a novel environment to directing the patterns of evolutionary change. As the specific nature of plasticity can impact evolutionary consequences, it is essential to consider how plasticity is manifested if we are to understand the contribution of plasticity to phenotypic evolution. Most morphological traits are developmentally plastic, irreversible, and generally considered to be costly, at least when the resultant phenotype is mis-matched to the environment. At the other extreme, behavioral phenotypes are typically activational (modifiable on very short time scales), and not immediately costly as they are produced by constitutive neural networks. Although patterns of morphological and behavioral plasticity are often compared, patterns of plasticity of life history phenotypes are rarely considered. Here we review patterns of plasticity in these trait categories within and among populations, comprising the adaptive radiation of the threespine stickleback fish Gasterosteus aculeatus. We immediately found it necessary to consider the possibility of iterated development, the concept that behavioral and life history trajectories can be repeatedly reset on activational (usually behavior) or developmental (usually life history) time frames, offering fine tuning of the response to environmental context. Morphology in stickleback is primarily reset only in that developmental trajectories can be altered as environments change over the course of development. As anticipated, the boundaries between the trait categories are not clear and are likely to be linked by shared, underlying physiological and genetic systems.

The covid-19 pandemic shows that where, when, how, and to whom care is delivered has never been more diverse. In today's healthcare, the people delivering care must be similarly diverse, for the benefit of the profession, its practitioners, and patients. 1 -3 Yet around 90% of the world's nurses are women. 4 Calls are being made, as they have before, to examine ways to promote the profession among men to tackle this imbalance. 1 5 Nursing is an inherently human experience: it is done for humans, by humans, and as humans, and in human experience no one gender claims primacy. Men have had, and continue to have, a valuable contribution to make to nursing, not simply because they are male but because they are human. Men enter the profession for the same reason as women-to care for people.

Context: Continuing professional development (CPD) activities for healthcare professionals are central to the optimisation of patient safety and person-centred care.Although there is some evidence on the economics of healthcare professionals training, very little is known about the costs and benefits of CPD. Methods: This study aimed to review the research evidence on economic evaluations of CPD activities for healthcare professionals. CINAHL, MEDLINE/PubMed, Scopus, Econlit and Web of Science databases were used to identify articles published between 2010 and 2021. Results: Of the 6791 titles identified, 119 articles met the inclusion criteria and were included in this scoping review. The majority of articles were partial economic evaluations of CPD programmes (n = 70); half were from the USA. Studies that included multiple professions were most prevalent (n = 54), followed by nurses (n = 34) and doctors (n = 23). Patient outcomes were the most commonly reported outcome (n = 51), followed by change in clinical practice (n = 38) and healthcare professionals' knowledge gain (n = 19).Conclusions: There is an urgent call for more evidence regarding the economic evaluations of CPD. This is particularly important in view of the rising costs of healthcare globally. The majority of studies included in this review did not provide detailed information on the evaluations and many focused exclusively on the cost of CPD activities rather than outcomes.

A code of ethics for the practice of nursing seeks to capture, in a written document, the normative values, ethical principles and standards of good care to guide nurses – qua moral agents. A codification of the accepted collective values of nursing can play a constitutional and directional role for the profession. It can further stimulate discussions about nursing that reflect the dynamic essence of the profession. Consequently, there is merit to continually reflecting on a code’s function and role especially when a new or revised code is introduced to the nursing profession and the wider public such as the European Nursing Council’s Code of Ethics and Conduct for European Nursing. This paper examines codes of ethics in general and the European Nursing Council Code in particular using the framework of Gaumnitz and Lere. Although the European Nursing Council Code has all the ingredients of a contemporary professional ethics code, our position is that future iterations or addenda to this Code should be aligned to the UN Sustainable Development Goals and take a more radical step in becoming an exemplar of a nursing code that can be a catalyst for the advancement of the Sustainable Development Goals.
