Cryoconite holes have ecological and biotechnological importance. This article presents results on culturable cryophilic yeasts and filamentous fungi isolated from cryoconite holes at Austre and Vestre Brøggerbreen glaciers, Svalbard. Based on DNA sequence data, these were identified as Rhodotorula sp., Thelebolus sp., and Articulospora tetracladia. Amongst these, Articulospora tetracladia (88.7–89.4% gene similarity with 5.8S rDNA) is a novel species, yet to be described. Filamentous fungus Articulospora sp. Cry-FB1 and Cry-FB2, expressed high amylase, cellulase, lipase and protease activities while yeast Rhodotorula sp. Cry-FB3 showed high amylase and cellulase activity. Thelebolus sp. Cry-YB 240 and Cry-YB 241 showed protease and urease activities. The effects of temperature, and salt on the growth of the cultures were studied. Optimum temperature of growth was on 10ºC at pH 7.0. Filamentous fungi and yeast in the cryoconite holes possibly drive the process of organic macromolecule degradation through cold-adapted enzyme secretion, thereby assisting in nutrient cycling in these supraglacial environments. Further, these cryophilic fungi, due to their enzyme producing ability, may provide an opportunity for biotechnological research in the Arctic.

Pollen- and non-pollen-palynomorphs (NPP) analytical studies of the northwestern part of Spitsbergen were conducted between 1988 and 1991. As well as pollen from local native flora and more dispersed species, some well preserved remains of tardigrada exuvia, buccal tubes and eggs were found. This study reviewed the remains of at least six tardigrade taxa reported: Dactylobiotus ambiguous, Paramacrobiotus richtersi group, Richtersius coronifer, Macrobiotus hufelandi group, Macrobiotus peterseni and Minibiotus cf. intermedius, which are reassessed and determined more accurately. These findings provide some new insights into the past environmental conditions and changes for Spitsbergen. Based on the present research it can be concluded that tardigrade remains are frequent NPP elements of pollen analyses from lake, peat bogs and detritus sub-fossil sediment cores, at least in polar regions. It can also be stated that tardigrades can be considered indicators in further palaeontological studies helping to reconstruct past environmental conditions (for example humidity) for some regions. However, the knowledge of tardigrades in these types of analyses is still rather poor.

In 1931, the Hudson's Bay Company cargo steamer, SS Baychimo, was trapped in sea ice and abandoned in the Chukchi Sea off the northern coast of Alaska. Large amounts of scientific and navigational instruments and gear and personal items were left aboard, among them an ethnographic collection gathered in 1930 from Inuit groups in the Canadian Arctic by Richard Sterling Finnie. The ship was boarded several times over the next three years with items being salvaged by locals from nearby Wainwright and Barrow. In 1933, crew and passengers from MS Trader, a small trading vessel from Nome, boarded the abandoned ship and recovered several of Finnie's ethnological specimens. In 1934, Peter Palsson, crewmember of Trader, gave several ethnological specimens to members of the United States Department of the Interior-Alaska College Archaeological Expedition. That year, the Baychimo collection was accessioned to the nascent University of Alaska Museum (now, the University of Alaska Museum of the North). For over 80 years, the collection's relationships with Finnie, the Baychimo, and Palsson remained obscure, and its historical significance has just been rediscovered. This paper describes the collection and the path it took from the Baychimo to the University of Alaska Museum.

Over several years, the European Union (EU) has gradually developed its legal framework to assist in the proper application of EU environmental protection rules, both at Member State as well as at EU institutional levels. This article focuses on one particular and relatively recent emerging element of that supranational framework, namely the range of EU secondary legislative measures and provisions concerning the management of environmental inspections. In addition to appraising the extent of EU legislative engagement in relation to environmental inspections, this article reflects on certain challenges of a constitutional nature that the EU will need to address in the future if its intervention in this particular policy field is to continue to develop.

Behaviourism is the view that preferences, beliefs and other mental states in social-scientific theories are nothing but constructs re-describing people’s behaviour. Mentalism is the view that they capture real phenomena, on a par with the unobservables in science, such as electrons and electromagnetic fields. While behaviourism has gone out of fashion in psychology, it remains influential in economics, especially in ‘revealed preference’ theory. We defend mentalism in economics, construed as a positive science, and show that it fits best scientific practice. We distinguish mentalism from, and reject, the radical neuroeconomic view that behaviour should be explained in terms of brain processes, as distinct from mental states.

Contemporary theorists tend to think that the basic justification of human rights is instrumental, as efficient means for producing the theorist's preferred ultimate value or values. Contemporary theorists also tend to think that human rights have a distinctive normative force, correlating with categorical duties. This article shows that instrumentalist accounts of human rights face a dilemma. The very structure of any instrumentalist account means that such an account faces extraordinary difficulties accommodating categorical duties to respect the human rights of others. If so, one should either reject instrumentalism about human rights or do away with categorical duties. But doing away with categorical duties comes at a high cost. The dilemma, then, should question the prevalent assumption that instrumentalist accounts of human rights can accommodate categorical duties. The dilemma should serve either to sharpen instrumentalist theories or to motivate non-instrumentalism about human rights.

It's been argued that better-than is non-transitive – that there are some value bearers for which better-than fails to generate an acyclic ordering. Michael Huemer has offered a powerful objection to this view, which he dubs ‘The Dominance Argument’. In what follows, I consider the extent to which there is a plausible response to be made on behalf of those who hold that better-than is non-transitive. I conclude that there is.
