Bostonia. Volume 28

Founded in 1900, Bostonia magazine is Boston University's main alumni publication, which covers alumni and student life, as well as university activities, events, and programs

Angewandte Linguistik für Sprachberufe

This volume introduces applied linguistics for language-based professions. Learning and practicing with both book and an online offering promotes academically rigorous thinking and action in everyday professional life, which is increasingly being shaped by artificial intelligence. This second edition contains new, updated exercise materials that provide in-depth illustrations, documentation, and reflections on existing basic knowledge

High spectral resolution of GaAs/AlAs phononic cavities by subharmonic resonant pump-probe excitation

We present here precise measurement of the resonance frequency, lifetime and shape of confined acoustic modes in the tens of GHz regime in GaAs/AlAs superlattice planar and micropillar cavities at low temperature ($\sim 20\,\textrm{K}$). The subharmonic resonant pump-probe technique, where the repetition rate of the pump laser is tuned to a subharmonic of the cavity resonance to maximize the amplitude of the acoustic resonance, in combination with a Sagnac interferometer technique for high sensitivity ($\sim 10 \,\textrm{fm}$) to the surface displacement, has been used. The cavity fundamental mode at $\sim 20\,\textrm{GHz}$ and the higher order cavity harmonics up to $\sim 180\,\textrm{GHz}$ have been clearly resolved. Mechanical Q-values up to $2.7 \times 10^4$ have been measured in a planar superlattice, and direct spatial mapping of confined acoustic modes in a superlattice cavity micropillar has been demonstrated. The Q-frequency product obtained is $\sim 5 \times 10^{14}$ demonstrating the suitability of these superlattice cavities for optomechanical applications.Comment: 5 pages, 4 figure

The Linguistics of Newswriting

The Linguistics of Newswriting focuses on text production in journalistic media as both a socially relevant field of language use and as a strategic field of applied linguistics. The book discusses and paves the way for scientific projects in the emerg­ing field of linguistics of newswriting. From empirical micro and theoretical macro perspectives, strategies and practices of research development and knowledge transformation are discussed. Thus, the book is addressed to researchers, teachers and coaches interested in the linguistics of professional writing in general and news­writing in particular. Together with the training materials provided on the internet www.news-writing.net, the book will also be useful to anyone who wants to become a more “discerning consumer" (Perry, 2005) or a more reflective producer of language in the media

Beyond single modes and media : writing as an ongoing multimodal text production

In this chapter, we focus on new, hybrid forms of text production and their research. We start from the practical example of Wikipedia, and the ways in which articles are developed quickly and then refined over time by Wikipedians (Part 1). This approach illustrates transitions from a narrow to a broader orientation in writing research (2). We then develop a framework for the state-of-the-art analysis of writing as a focused and incidental, by-the-way activity of producing editable and storable multimodal communication offers (3). Within this framework, challenges for and controversial issues of contemporary writing research can be identified (4). This allows us to outline what such research can contribute to Applied Linguistics (5) and to sketch a related research roadmap (6). Finally, in the reference section, we list key publications that explain writing research beyond single modes and media (7)

Production modes : writing as materializing and stimulating thoughts

In this chapter, we systematize and discuss research on writing and text production as a highly interrelated mode of language use. We start from two examples of professional writing that complement each other: one is about writing in financial communication, the other about not writing in public discourse (Part 1). These examples help us illustrate the transition from a detached to an integrative view of writing in text production research (2). We then develop a framework for the integrative analysis of writing as a key mode of language use (3). Within this framework, challenges for and controversial issues of contemporary writing research are identified (4). This allows us to outline what such research can contribute to and benefit from applied linguistics (5) and to sketch a related research roadmap (6). In the reference section, we focus on work explaining the interplay of writing and other modes of language use as mental and societal processes (7)
