Aquaculture is the fastest growing animal producing sector in the world and is expected to play an important role in global food supply. Along with this growth, concerns have been raised about the environmental effects of escapees and pollution, fish welfare, and consumer health as well as the use of marine resources for producing fish feed. In this paper we present some of the major challenges salmon farming is facing today. We discuss issues of relevance to how to ensure sustainability, (...) by focusing on animal production systems, breeding approaches, sources for feed ingredients, and genetic engineering strategies. Other crucial issues such as animal welfare, environmental quality, and ethics are elaborated with regard to relevance for the sustainability of aquaculture. Additionally, we comment on socio-economic distributive implications by intellectual property rights (IPR) strategies on access to genetic material and traceability. To improve sustainability of salmon farming we suggest that there is a need for new approaches to guide research, for identification of ethical issues, and for engaging stakeholders in resolving these challenges.

Classical temples in ancient Greece show two deterministic illusionistic principles of architecture, which govern their functional design: geometric proportionalism and a set of illusion-strengthening rules in the proportionalism's stochastic margin. Animal morphology, in its mechanistic-deductive revival, applies just one architectural principle, which is not always satisfactory. Whether a Greek Classical situation occurs in the architecture of living structure is to be investigated by extreme testing with deductive methods.Three deductive methods for explanation of living structure in animal morphology are proposed: the (...) parts, the compromise, and the transformation deduction. The methods are based upon the systems concept for an organism, the flow chart for a functionalistic picture, and the network chart for a structuralistic picture, whereas the optimal design serves as the architectural principle for living structure. These methods show clearly the high explanatory power of deductive methods in morphology, but they also make one open end most explicit: neutral issues do exist. (shrink)

In recent years, “deliberation” has become the byword of many political theorists, most of whom identify deliberation with reasoned conversation. Among the most forceful advocates of deliberation as conversation are Jürgen Habermas and, to a greater or lesser extent, his successors who style themselves “deliberative democrats.” For them, the more political decision‐making approximates the ideal of a reasoned public conversation among free and equal individuals, the more legitimate and rational it will be. “Outcomes,” they say are democratically legitimate if and (...) only if they could be the object of a free and reasoned agreement among equals. Their deliberative model produces more rational decision‐making, they say, because it conveys information, impels individuals to order their preferences coherently, and by making persons articulate good reasons in public leads them “to think from the standpoint of all involved.”.

Monitored Emergency Use of Unregistered and Experimental Interventions (MEURI) is an ethical framework developed by the WHO for using unproven interventions in public health emergencies outside the context of medical research. It is mainly intended for use when medical research would be impracticable, but there is still a need to systematically gather data about unproven interventions. As such, it is designed as something of a middle ground between clinical and research ethical frameworks. However, I argue that MEURI does not truly (...) lie at the intersection of clinical care and research. Due to its intent, structure and oversight requirements, it takes on most of the crucial features of research, to the point that it is best understood as a form of research. As a result, cases where MEURI could practicably be applied should instead make use of existing research frameworks. For those circumstances where research is truly impracticable, a more straightforward oversight system than MEURI is needed. While existing practices of compassionate use have some applicability, proposals to make use of clinical ethics committees to oversee unproven interventions may help achieve the right balance in acting in a patient’s best interests when the relevant evidence base is weak.

We tend to assume that our map of the intellectual disciplines is valid cross-culturally. G. E. R. Lloyd challenges this in relation to eight main areas of human endeavour, namely philosophy, mathematics, history, medicine, art, law, religion, and science, by examining how the disciplines were conceived and developed in different times and places.

Open peer commentary on the article “Beyond Technocentrism: Supporting Constructionism in the Classroom” by Karen Brennan. Upshot: Brennan describes ways by which teachers can be supported to bypass a technocentric view of learning with technology in the classroom, from a constructionist perspective. She reports on the development of a corresponding model of professional development by describing the elements of the model and its design principles as well as the tensions that arose while trying to support teachers’ explorations and experiences in (...) the classroom. Questions arise about the potential of the model to be exploited to address issues underlying teachers’ professional development in different contexts. (shrink)
