This article describes and critically examines the challenging task of compiling The London–Lund Corpus 2 (LLC–2) from start to end, accounting for the methodological decisions made in each stage and highlighting the innovations. LLC–2 is a half-a-million-word corpus of contemporary spoken British English with recordings from 2014 to 2019. Its size and design are the same as those of the world's first machine-readable spoken corpus, The London–Lund Corpus of Spoken English with data from the 1950s to 1980s. In this way, LLC–2 allows not only for synchronic investigations of contemporary speech but also for principled diachronic research of spoken language across time. Each stage of the compilation of LLC–2 posed its own challenges, ranging from the design of the corpus, the recruitment of the speakers, transcription, markup and annotation procedures, to the release of the corpus to the international research community. The decisions and solutions represent state-of-the-art practices of spoken corpus compilation with important innovations that enhance the value of LLC–2 for spoken corpus research, such as the availability of both the transcriptions and the corresponding time-aligned audio files in a standard compliant format.

The idea of this special issue on Spoken language in time and across time emerged at an international symposium on this topic that we organised at Lund University on 20 September 2019. The purpose of the symposium was to celebrate important past and present achievements of spoken language research as well as past and present corpora available for such research. Some speakers reported on academic and technical advances from the past, while others offered information about state-of-the-art research on spoken language and spoken corpus compilation. Our idea with the symposium was also to bring together early career scholars, somewhat more senior scholars as well as senior scholars – the latter actually active when interest in spoken language and spoken corpus compilation was in its infancy. The type of spoken corpora in focus extended from the world's first publicly available, machine-readable spoken corpus, The London–Lund Corpus of Spoken English (Svartvik 1990), nowadays referred to as LLC–1, through to the spoken parts of The British National Corpora (BNC) from 1994 (BNC Consortium 2007) and 2014 (Love et al. 2017), The Diachronic Corpus of Present-Day Spoken English (DCPSE) consisting of LLC–1 and the British component of The International Corpus of English (ICE–GB), Santa Barbara Corpus of Spoken American English (SBCSAE) (Du Bois et al. 2000–5), The Corpus of Contemporary American English (COCA) (Davies 2008–) and finally the most recent one, The London–Lund Corpus 2 (LLC–2) (Põldvere, Johansson & Paradis 2021a). The symposium thus covered approximately half a century of data from publicly available corpora compiled for multipurpose use by the academic community for research on spoken English in different contexts.

Constrained Devices

The application of Artificial Intelligence to the industrial world and its appliances has recently grown in popularity. Indeed, AI techniques are now becoming the de-facto technology for the resolution of complex tasks concerning computer vision, natural language processing and many other areas. In the last years, most of the the research community efforts have focused on increasing the performance of most common AI techniques—e.g., Neural Networks, etc.—at the expenses of their complexity. Indeed, many works in the AI field identify and propose hyper-efficient techniques, targeting high-end devices. However, the application of such AI techniques to devices and appliances which are characterised by limited computational capabilities, remains an open research issue. In the industrial world, this problem heavily targets low-end appliances, which are developed focusing on saving costs and relying on—computationally—constrained components. While some efforts have been made in this area through the proposal of AI-simplification and AI-compression techniques, it is still relevant to study which available AI techniques can be used in modern constrained devices. Therefore, in this paper we propose a load classification task as a case study to analyse which state-of-the-art NN solutions can be embedded successfully into constrained industrial devices. The presented case study is tested on a simple microcontroller, characterised by very poor computational performances—i.e., FLOPS –, to mirror faithfully the design process of low-end appliances. A handful of NN models are tested, showing positive outcomes and possible limitations, and highlighting the complexity of AI embedding.

Modal Auxiliaries

A number of recent studies of grammatical categories in English have identified regional and diachronic variation in the use of the present perfect, suggesting that it has been losing ground to the simple past tense from the eighteenth century onwards ( Elsness, 1997 , 2009 ; Hundt and Smith, 2009 ; and Yao and Collins, 2012 ). Only a limited amount of research has been conducted on non-present perfects. More recently, Bowie and Aarts’ (2012) study using the Diachronic Corpus of Present-Day Spoken English has found that certain non-present perfects underwent a considerable decline in spoken British English (BrE) during the second half of the twentieth century. However, comparison with American English (AmE) and across various genres has not been made. This study focusses on the changes in the distribution of four types of non-present perfects (past, modal, to-infinitival and ing-participial) in standard written BrE and AmE during the thirty-year period from the early 1960s to the early 1990s. Using a tagged and post-edited version of the Brown family of corpora, it shows that contemporary BrE has a stronger preference for non-present perfects than AmE. Comparison of four written genres of the same period reveals that, for BrE, only the change in the overall frequency of past perfects was statistically significant. AmE showed, comparatively, a more dramatic decrease, particularly in the frequencies of past and modal perfects. It is suggested that the decline of past perfects is attributable to a growing disfavour for past-time reference in various genres, which is related to long-term historical shifts associated with the underlying communicative functions of the genres. The decline of modal perfects, on the other hand, is more likely to be occurring under the influence of the general decline of modal auxiliaries in English.

Acetoin is an important four-carbon compound that has many applications in foods, chemical synthesis, cosmetics, cigarettes, soaps, and detergents. Its stereoisomer (S)-acetoin, a high-value chiral compound, can also be used to synthesize optically active drugs, which could enhance targeting properties and reduce side effects. Recently, considerable progress has been made in the development of biotechnological routes for (S)-acetoin production. In this review, various strategies for biological (S)- acetoin production are summarized, and their constraints and possible solutions are described. Furthermore, future prospects of biological production of (S)-acetoin are discussed.

AbstractTechnology-based education of children with special needs has become the focus of many research works in recent years. The wide range of different disabilities that are encompassed by the term “special needs”, together with the educational requirements of the children affected, represent an enormous multidisciplinary challenge for the research community. In this article, we present a systematic literature review of technology-enhanced and game-based learning systems and methods applied on children with special needs. The article analyzes the state-of-the-art of the research in this field by selecting a group of primary studies and answering a set of research questions. Although there are some previous systematic reviews, it is still not clear what the best tools, games or academic subjects (with technology-enhanced, game-based learning) are, out of those that have obtained good results with children with special needs. The 18 articles selected (carefully filtered out of 614 contributions) have been used to reveal the most frequent disabilities, the different technologies used in the prototypes, the number of learning subjects, and the kind of learning games used. The article also summarizes research opportunities identified in the primary studies.

Since the early 1990s, with the advance of computerized corpora, translation scholars have been using corpus-based methodologies to look into the possible existence of overriding patterns (tentatively described as universals or as laws) in translated texts. The application of such methodologies to interpreted texts has been much slower in developing than in the case of translated ones, but significant progress has been made in recent years. After presenting the fundamental methodological hurdles—and advantages—of working on machine-readable (transcribed) oral corpora, we present and discuss several recent studies using cross-modal comparisons, and examine the viability of using interpreted outputs to explore the features that set simultaneous interpreting apart from other forms of translation. We then set out to test the hypothesis that modality may exert a stronger effect than ontology—i.e. that being oral (vs. written) is a more powerful influence than being translated (vs. original).

In summary, it can be said that progress is being made in the field, but slowly. The ‘art’ is vigorous, vital and exciting. The ranks of family therapists are swelling and they are coming from backgrounds of different theoretical persuasions and with varying degrees of sophistication in their training and education. This mélange does lead to excitement and turbulence but often detracts from the necessary rigour that a scientific discipline must develop in order to reach maturity. Systems theory allows for easy conceptualization of one another's behaviour in the system, and permits a much clearer understanding of the therapeutic process based upon it, in contrast to therapeutic approaches based on other models. The authors found negotiation to be therapeutically effective when made explicit. In addition they place the focus on the ‘here and now’ and encourage the increased labeling by family members of interactions (affective and behavioural) and their effects (affective and behavioural), according to the Family Categories Schema previously referred to. Efforts are directed especially towards dealing with the current resistances to problem solutions. Epstein et al. have reported on an ongoing program of research which attempts to examine the process and outcome of family therapy (7,10,21,22,25,26). What is needed now is a more rigorous approach to research and the development of a necessary theoretical base in order that a more systematic and scientific approach can be developed for treating families.

This paper presents the state of the art on interoperability developments for the social and solidarity economy (SSE) community web based information systems (WIS); it also presents a framework of interoperability for the SSE' WIS and the developments made in a research-in-progress PhD project in the last 3 years. A search on the bibliographic databases showed that so far there are no papers on interoperability initiatives on the SSE, so it was necessary to have other sources of information: a preliminary analysis of the WIS that support SSE activities; and interviews with the representatives of some of the world's most important SSE organisations. The study showed that the WIS are still not interoperable yet. In order to become interoperable a group of the SSE community has been developing a Dublin Corre Application Profile to be used by the SSE community as reference and binding to describe their resources. This paper also describes this on-going process.
