Comparing Suffering Across Species, John Nolt

Between the Species

Moral life often presents us with trade-offs between the sufferings of some individuals and the sufferings of others. Researchers may need to consider, for example, whether the suffering imposed on animals by a certain line of medical experimentation justifies the relief that the resulting discoveries may bring to (human or non-human) others. Often in such cases, the suffering of some individuals is incomparable with—that is neither greater than nor less than nor equal to—the suffering of others. While this complicates moral decision-making across species, it does not undermine it.

Towards A Coherent Theory Of Animal Equality, Stijn Bruers

Between the Species

In this article I want to construct in a simple and systematic way an ethical theory of animal equality. The goal is a consistent theory, containing a set of clear and coherent universalized ethical principles that best fits our strongest moral intuitions in all possible morally relevant situations that we can think of, without too many arbitrary elements. I demonstrate that impartiality with a level of risk aversion and empathy with a need for efficiency are two different approaches that both result in the same consequentialist principle of prioritarianism. Next, I discuss that this principle can be trumped by an …

Genetic Diversity And Population Parameters Of Sea Otters, Enhydra Lutris, Before Fur Trade Extirpation From 1741–1911, Shawn Larson, Ron Jameson, Michael Etnier, Terry L. Jones, Roberta Hall

Social Sciences

All existing sea otter, Enhydra lutris, populations have suffered at least one historic population bottleneck stemming from the fur trade extirpations of the eighteenth and nineteenth centuries. We examined genetic variation, gene flow, and population structure at five microsatellite loci in samples from five pre-fur trade populations throughout the sea otter’s historical range: California, Oregon, Washington, Alaska, and Russia. We then compared those values to genetic diversity and population structure found within five modern sea otter populations throughout their current range: California, Prince William Sound, Amchitka Island, Southeast Alaska and Washington. We found twice the genetic diversity in the pre-fur …

Toward A More Phronetic Leisure Science, Daniel Dustin, Keri Schwab, Jeff Rose

Recreation, Parks and Tourism Administration

In this essay, we examine the assumptions underlying natural science, social science, and the humanities. More specifically, we suggest that social science in general and leisure science in particular be guided by a different set of assumptions than those guiding natural science and the humanities. Drawing on the Aristotelian idea of phronesis, we propose that value rationality more so than instrumental rationality guide social scientific inquiry, and that social science in general, and leisure science in particular, be viewed as a bridge between natural science and the humanities.
