Three new species of Leohumicola (anamorphic Leotiomycetes) are described using morphological characters and phylogenetic analyses of DNA barcodes. Leohumicola levissima and L. atra were isolated from soils collected after forest fires in Crater Lake National Park, United States. Leohumicola incrustata was isolated from burned fynbos from the Cape of Good Hope Nature Reserve, South Africa. The ...
This thesis concerns quantum cluster algebras. For skew-symmetric acyclic quantum cluster algebras, we express the quantum F -polynomials and the quantum cluster monomials in terms of Serre polynomials of quiver Grassmannians of rigid modules. Then we introduce a new family of graded quiver varieties together with a new t-deformation, and generalize Nakajima’s t-analogue of q-characters to thes...
Rosso and Green have shown how to embed the positive part Uq(n) of a quantum enveloping algebra Uq(g) in a quantum shuffle algebra. In this paper we study some properties of the image of the dual canonical basis B∗ of Uq(n) under this embedding Φ. This is motivated by the fact that when g is of type Ar, the elements of Φ(B∗) are q-analogues of irreducible characters of the affine Iwahori-Hecke ...
We establish a correspondence (or duality) between the characters and the crystal bases of finite-dimensional representations of quantum groups associated to Langlands dual semi-simple Lie algebras. This duality may also be stated purely in terms of semi-simple Lie algebras. To explain this duality, we introduce an “interpolating quantum group” depending on two parameters which interpolates bet...
This paper confirms that the English verb system (similar to the Finnish, Dutch, and Bulgarian verb systems [17, 22]) represents path curvature at three different grain levels: neutral path curvature, global path curvature, and local path curvature. We show that the three-grain-level hypothesis makes it possible to formulate constraints on English sentence structure and makes it possible to def...
the main purpose of this study was to investigate any relationship between high school efl teachers metaphorical understandings of their role in class and their self-efficacy beliefs. teachers metaphors were elicited through two different prompts: one picturing what they believed a language teacher should be like in class, and the other demonstrating what they are actually like in class; such...
How do different media cover politics and affect voters? Are newspapers a boon and television a bane to democratic functioning? While these questions have long been the subject of debate, a variety of methodological hurdles have hampered prior attempts to document media differences and their effects. In this article, I discuss these challenges and offer an approach for overcoming them to the gr...

This paper discusses the competitive factor in knowledge sharing networks. Organisations are dependent on other, often even competing organisations for their knowledge. When competing organisations co-operate in alliances to be able to learn from and with each other it becomes likely that they meet an interorganisational learning dilemma (Larsson, Bengtsson, Henriksson & Sparks, 1998); will eac...
