Application of DWF to heavy-light mesons

We consider application of domain wall fermions to quarks with relatively heavy masses, aiming at precision calculations of charmed meson properties. Preliminary results for a few basic quantities are presented.Comment: Lattice2003(heavy), 3 pages, 3 figure

Veterinary Students as Global Citizens: Exploring opportunities for embedding the global dimension in the undergraduate veterinary curriculum

Veterinary medicine has an increasingly important role to play in addressing the global challenges of the 21st century, particularly in working towards worldwide disease control and food security. This contribution will be vital in the face of pressures resulting from a rapidly expanding, increasingly mobile human population and climate change. Globalisation will, conversely, also see world affairs impacting upon veterinary practice in the United Kingdom as never before. Veterinary undergraduate education must reflect these challenges and equip tomorrow?s veterinary surgeons with the knowledge and skills that they will require to practise in a rapidly changing world, and to contribute effectively to society?s needs. This report explores the contributions that veterinary medicine can make to global health and development and highlights the need for improved undergraduate teaching in this area. The report also reflects on how this might be achieved and the barriers to change, including limited space within undergraduate curricula, approaches to teaching and learning, perceptions of the relevance of global health to training and professional development, and the need for greater support from relevant professional bodies. Finally, it makes a number of recommendations for future work on these issues within UK veterinary education

Optical investigations of noncrystalline semiconductors

Three areas of investigation into the properties of amorphous silicon and boron are reported: (1) optical properties of elemental amorphous semiconductors; (2) Mossbauer studies of disordered systems; and (3) theoretical aspects of disordered semiconductors

Study Abroad as a Route to Global Citizenship: Student Perspectives in the UK

Universities around the world invest significant resources in developing study abroad programmes, often with a diverse range of aims – including promoting individual student learning and development, as well as enhancing mobility and employability. While the experience of studying abroad is also frequently cited as a key route to helping undergraduate students to develop global perspectives and global citizenship, it remains unclear to what extent the learning which takes place actually supports that aim. There are also on-going debates about the relative value of different perspectives on what constitutes a ‘global citizen’, and particularly whether this revolves around mobility and employability or the development of criticality and a sense of care and social justice. The frequent mismatch between programme aims and students’ own interests often further complicates this discussion. This chapter therefore explores the perspectives of students on their own experiences of study abroad and both its potential and challenges for developing a global perspective. It is based on a small-scale study of undergraduate students enrolled in the BASc Arts and Sciences degree at University College London (UK), all of whom studied abroad as part of their degree course. The research included a literature review, an anonymous online questionnaire and a series of interviews with students, and analysis of study abroad dissertations. The chapter explores the students’ perspectives on (i) how the study abroad experience had an impact on their world outlook and their views of global citizenship, (ii) the extent to which it enabled them to develop new knowledge and skills, and (iii) how the experience may have influenced their plans for the future

A near-infrared survey for Galactic Wolf-Rayet stars

Initial results, techniques, and rationale for a near-infrared survey of evolved emission-line stars toward the Galactic Center are presented. We use images taken through narrow-band emission-line and continuum filters to select candidates for spectroscopic follow-up. The filters are optimized for the detection of Wolf-Rayet stars and other objects which exhibit emission-lines in the 2 micron region. Approximately three square degrees along the Galactic plane have been analyzed in seven narrow-filters (four emission-lines and three continuum). Four new Wolf-Rayet stars have been found which are the subject of a following paper.Comment: 10 pages, 2 figures, accepted for publication in A&

Subgap features due to quasiparticle tunneling in quantum dots coupled to superconducting leads

We present a microscopic theory of transport through quantum dot set-ups coupled to superconducting leads. We derive a master equation for the reduced density matrix to lowest order in the tunneling Hamiltonian and focus on quasiparticle tunneling. For high enough temperatures transport occurs in the subgap region due to thermally excited quasiparticles, which can be used to observe excited states of the system for low bias voltages. On the example of a double quantum dot we show how subgap transport spectroscopy can be done. Moreover, we use the single level quantum dot coupled to a normal and a superconducting lead to give a possible explanation for the subgap features observed in the experiments published in Appl. Phys. Lett. 95, 192103 (2009).Comment: 18 pages, 20 figures, revised according to published versio

Berry-phase blockade in single-molecule magnets

We formulate the problem of electron transport through a single-molecule magnet (SMM) in the Coulomb blockade regime taking into account topological interference effects for the tunneling of the large spin of a SMM. The interference originates from spin Berry phases associated with different tunneling paths. We show that in the case of incoherent spin states it is essential to place the SMM between oppositely spin-polarized source and drain leads in order to detect the spin tunneling in the stationary current, which exhibits topological zeros as a function of the transverse magnetic field.Comment: 4 pages, Revtex 4, 4 EPS figure

Human Trafficking and the Media

This paper focuses on how the media can affect the publics knowledge about human trafficking. Specific attention is paid to what human trafficking is and what the different types of criteria that need to be met are. Of the criteria that is met, the paper looks at the overlapping of requirements between human trafficking and other offenses. More importantly throughout the paper is analyzations on police officers’ beliefs about knowing what human trafficking is, what still needs to be done, and their stance on the current definition. The research presented demonstrates the need for more positive psychological approaches when talking to a victim of human trafficking as they are already a part of a vulnerable group and the need to implement clearer terminology to establish modernized laws and programs
