Abstract

For speaking, words in the lexicon are somehow activated from conceptual representations but we know surprisingly little about how this works precisely. Which of the attributes of the concept DOG (e.g. BARKS, IS WALKED WITH A LEASH, CARNIVORE, ANIMATE) have to be activated in a given situation to be able to select the word ‘dog’? Are there things we know about dogs that are always activated for naming and others that are only activated in certain contexts or even never? To date, investigations on lexical access in speaking have largely focused on the effects of distractor nouns on the naming latency of a target noun. We have learned that distractors from the same semantic category (e.g. ‘cat’) hinder naming, but associatively related distractors (‘leash’) may facilitate or hinder naming. However, associatively related words can have all kinds of semantic relationships to a target word, and, with few exceptions, the effects of specific semantic relationships other than membership in the same category as the target concept have not been systematically investigated. This special issue aims at moving forward towards a more detailed account of how precisely conceptual information is used to access the lexicon in speaking and what corresponding format of conceptual representations needs to be assumed.

Abstract

Speech production and perception are two of the most complex actions humans perform. The processing of speech is studied across various fields and using a wide variety of research approaches. These fields include, but are not limited to, (socio)linguistics, phonetics, cognitive psychology, neurophysiology, and cognitive neuroscience. Research approaches range from behavioural studies to neuroimaging techniques such as Magnetoencephalography, electroencephalography (MEG/EEG) and functional Magnetic Resonance Imaging (fMRI), as well as neurophysiological approaches, such as the recording of Motor Evoked Potentials (MEPs), and Transcranial Magnetic Stimulation (TMS). Each of these approaches provides valuable information about specific aspects of speech processing. Behavioural testing can inform about the nature of the cognitive processes involved in speech processing, neuroimaging methods show where (fMRI and MEG) in the brain these processes take place and/or elucidate on the time-course of activation of these brain areas (EEG and MEG), while neurophysiological methods (MEPs and TMS) can assess critical involvement of brain regions in the cognitive process. Yet, what is currently unclear is how speech researchers can combine methods such that a convergent approach adds to theory/model formulation, above and beyond the contribution of individual component methods? We expect that such combinations of approaches will significantly forward theoretical development in the field. The present research topic comprise a collection of manuscripts discussing the cognitive and neural organisation of speech processing, including speech production and perception at the level of individual speech sounds, syllables, words, and sentences. Our goal was to use findings from a variety of disciplines, perspectives, and approaches to gain a more complete picture of the organisation of speech processing. The contributions are grouped around the following five main themes: 1) Spoken language comprehension under difficult listening conditions; 2) Sub-lexical processing; 3) Sensorimotor processing of speech; 4) Speech production. The contributions used a variety of research approaches, including behavioural experiments, fMRI, EEG, MEG, and TMS. Twelve of the 14 contributions were on speech perception processing, and the remaining two examined speech production. This Research Topic thus displays a wide variety of topics and research methods and this comprehensive approach allows an integrative understanding of currently available evidence as well as the identification of concrete venues for future research.

Abstract

Gut health and specifically the gut microbiome-host interaction is currently a major research topic across the life sciences. In the case of animal sciences research into animal production and health, the gut has been a continuous area of interest. Production parameters such as growth and feed efficiency are entirely dependent on optimum gut health. In addition, the gut is a major immune organ and one of the first lines of defense in animal disease. Recent changes in animal production management and feed regulations, both regulatory and consumer driven, have placed added emphasis on finding ways to optimize gut health in novel and effective ways. In this volume we bring together original research and review articles covering three major categories of gut health and animal production: the gut microbiome, mucosal immunology, and feed-based interventions. Included within these categories is a broad range of scientific expertise and experimental approaches that span food animal production. Our goal in bringing together the articles on this research topic is to survey the current knowledge on gut health in animal production. The following 15 articles include knowledge and perspectives from researchers from multiple countries and research perspectives, all with the central goal of improving animal health and production.

Abstract

The present collection of articles brings together experimental work in the field of segmental and prosodic processing and representation in phonology and phonetics. Contributions focus on the exploration of human cognitive, articulatory, and perceptual abilities dealing with all types of phonetic and phonological entities. Main topics of investigation include: (1) sounds and sound-changing processes—systemic and functional aspects, (2) prosodic units such as syllables and metrical feet—systemic properties, processing, and phonetic consequences, and (3) tones as building blocks of the sentence melody—their relation to the level of linguistic expressions on the one hand, their phonetic realization (e.g., tonal height and contours) and perception on the other hand. In addition, topics (1) and (2) extend to the question how phonological representations are stored in the mental lexicon: specified minimally in terms of categorical phonological information or as variable phonetic imprint of the exemplars in the input. Diagonally to these thematic domains, the present Research Topic shows a strong focus on up-to-date experimental approaches, going far beyond traditional linguistic analysis, and making use of psycho- and neurolinguistic methodologies.

Abstract

In livestock species, breeding goals are aimed primarily at improvement of production traits. However, there are a number of examples where selection for high production efficiency has resulted in reduced welfare through unfavorable outcomes in health and fitness characteristics. These effects raise questions about what is ethically acceptable in animal breeding. Welfare problems may be experienced when physiological balance is disturbed by genetic selection for high production alone, by a mismatch between the environmental challenges and the range of coping responses available to an animal, or from a mismatch between the animal’s needs and their degree of satisfaction. This may be resolved by either improving the environment to support the animal, but also by providing the animal, through genetic selection, with means to adapt to the production environment. The Standing Committee of the European Convention for the Protection of Animals kept for Farming Purposes emphasizes that breeding goals should include health and welfare. The Farm Animal Welfare Council pleas for a greater emphasis in breeding programs on traits associated with good welfare. However, although breeding goals in most farm animal species have been broadened beyond production traits to include functional traits, behavioral traits are rarely included despite their potential to improve animal production and welfare. It is the goal of the present Research Topic to bring together experimental and theoretical research focusing on the genetics of welfare traits and the possibility to improve animal welfare through selection. This topic presents an overview of the relationship between selection for high production and livestock robustness, examples of improving robustness through the introduction of novel traits in livestock breeding, and a discussion on selection methods to address welfare issues. The discussion on sustainability of breeding practices is very alive today and will remain to be an important part of the debate in the future.

Abstract

For decades, human cognition involved in reading aloud and speech production has been investigated extensively (a quote search of the two in google scholar produces about 83,000 and 255,000 results, respectively). This large amount of research has produced quite detailed descriptions of the cognitive mechanisms that allow people to speak or to read aloud a word. However, despite the fact that reading aloud and speech production share some processes – generation of phonology and preparation of a motor speech response – the research in this two areas seems to have taken parallel and independent tracks, with almost no contact between the two. The present Research Topic takes an initial step towards building a bridge that will link the two research areas, as we believe that such an endeavour is essential for moving forward in our understanding of how the mind/brain processes words. To this aim, we encourage contributions exploring the relation between speech production and reading aloud. The questions the Research Topic should address include, but are not limited to, the following: To what extent are speech production and word reading/reading aloud similar? Are there some shared components and/or mechanisms between the two process? Is the time course of the (supposed) shared mechanisms activation similar in the two processes? How does the different input (conceptual vs. orthographic) interact with the types of information that reading and speaking share (semantic and phonological knowledge, articulatory codes)? How does a difference in the input affect the (supposed) common stages of processing (i.e., phonological encoding, and articulatory planning and execution)? We welcome any kind of contribution (e.g., original research article, review, opinion) that answers the above or other questions related to the Topic.

Abstract

Composite and multiple-text manuscripts are traditionally studied for their individual texts, but recent trends in codicology have paved the way for a more comprehensive approach: Manuscripts are unique artefacts which reveal how they were produced and used as physical objects. While multiple-text manuscripts codicologically are to be considered as production units, i.e. they were originally planned and realized in order to carry more than one text, composites consist of formerly independent codicological units and were put together at a later stage with intentions that might be completely different from those of its original parts. Both sub-types of manuscripts are still sometimes called "miscellanies", a term relating to the texts only. The codicological difference is important for reconstructing why and how these manuscripts which in many cases resemble (or contain) a small library were produced and used. Contributions on the manuscript cultures of China, India, Africa, the Islamic world and European traditions lead not only to the conclusion that "one-volume libraries" have been produced in many manuscript cultures, but allow also for the identification of certain types of uses.

Abstract

Achieving the ambitious greenhouse gas (GHG) reduction targets set up by German legislation requires political incentives to reduce GHG emissions of energy intensive industries without hampering their international competitiveness. This dissertation therefore analyses the influence of different political instruments (ETS, EEG, EnergieStG, StromStG) on induced emission reductions as well as on relevant economic parameters. Thereby, the focus is set on the metal production.

Abstract

This volume highlights new avenues of research in the language sciences, and particularly, in the neurobiology of language. The term “language-ready brain” stresses, on the one hand, the importance of a brain-based description of our species’ linguistic capacity, and, on the other, the need to appreciate the crucial role culture plays in shaping the linguistic systems children acquire and adults use. For this reason, the focus is not put on language per se, but on our learning biases and cognitive pre-dispositions toward language. Both brain and culture are considered at two crucial levels of inquiry: phylogeny and ontogeny. In a fast-growing field like the language sciences and specifically, language evolution studies, this book has tried to capture several of the most exciting topics explored currently, sowing seeds for future investigations.
