The family Parvoviridae

Abstract: A set of proposals to rationalize and extend the taxonomy of the family Parvoviridae is currently under review by the International Committee on Taxonomy of Viruses (ICTV). Viruses in this family infect a wide range of hosts, as reflected by the longstanding division into two subfamilies: the Parvovirinae, which contains viruses that infect vertebrate hosts, and the Densovirinae, encompassing viruses that infect arthropod hosts. Using a modified definition for classification into the family that no longer demands isolation as long as the biological context is strong, but does require a near-complete DNA sequence, 134 new viruses and virus variants were identified. The proposals introduce new species and genera into both subfamilies, resolve one misclassified species, and improve taxonomic clarity by employing a series of systematic changes. These include identifying a precise level of sequence similarity required for viruses to belong to the same genus and decreasing the level of sequence similarity required for viruses to belong to the same species. These steps will facilitate recognition of the major phylogenetic branches within genera and eliminate the confusion caused by the near-identity of species and viruses. Changes to taxon nomenclature will establish numbered, non-Latinized binomial names for species, indicating genus affiliation and host range rather than recapitulating virus names. Also, affixes will be included in the names of genera to clarify subfamily affiliation and reduce the ambiguity that results from the vernacular use of “parvovirus” and “densovirus” to denote multiple taxon levels.

How approaches to teaching are affected by discipline and teaching context

Abstract: Two related studies are reported in this article. The first aimed to analyse how academic discipline is related to university teachers’ approaches to teaching. The second explored the effects of teaching context on approaches to teaching. The participants of the first study were 204 teachers from the University of Helsinki and the Helsinki School of Economics and Business Administration and 136 teachers from the University of Oxford and Oxford Brookes University who returned university teaching inventories. Thus, altogether there were 340 teachers from a variety of disciplines in Finland and the UK. The second study involved only the Finnish sample. The results showed that there was systematic variation in both student‐ and teacher‐focused dimensions of approaches to teaching across disciplines and across teaching contexts. These results confirm the relational nature of teachers’ approaches to teaching and illustrate the need, in using inventories such as the Approaches to Teaching Inventory, to be explic...

Spin and molecular electronics in atomically generated orbital landscapes

Abstract: Ab initio computational methods for electronic transport in nanoscaled systems are an invaluable tool for the design of quantum devices. We have developed a flexible and efficient algorithm for evaluating I-V characteristics of atomic junctions, which integrates the nonequilibrium Green’s function method with density functional theory. This is currently implemented in the package SMEAGOL. The heart of SMEAGOL is our scheme for constructing the surface Green’s functions describing the current-voltage probes. It consists of a direct summation of both open and closed scattering channels together with a regularization procedure of the Hamiltonian and provides great improvements over standard recursive methods. In particular it allows us to tackle material systems with complicated electronic structures, such as magnetic transition metals. Here we present a detailed description of SMEAGOL together with an extensive range of applications relevant for the two burgeoning fields of spin and molecular electronics.

Corpus Linguistics: Method, Theory and Practice

Abstract: Corpus linguistics is the study of language data on a large scale – the computer-aided analysis of very extensive collections of transcribed utterances or written texts This textbook outlines the basic methods of corpus linguistics, explains how the discipline of corpus linguistics developed and surveys the major approaches to the use of corpus data It uses a broad range of examples to show how corpus data has led to methodological and theoretical innovation in linguistics in general Clear and detailed explanations lay out the key issues of method and theory in contemporary corpus linguistics A structured and coherent narrative links the historical development of the field to current topics in 'mainstream' linguistics Practical tasks and questions for discussion at the end of each chapter encourage students to test their understanding of what they have read and an extensive glossary provides easy access to definitions of technical terms used in the text
