Broken Pairs and High-Spin States in Transitional Nuclei
No full textThe Interacting Boson plus broken-pairs Model has been used to describe high-spin bands in spherical and transitional nuclei. In the spherical nucleus 104Cd the model reproduces the structure of high-spin bands built on a vibrational structure. Model calculations performed with a single set of parameters reproduce ten bands in 136Nd
High-Spin Dipole Bands in Spherical and Transitional Nuclei
No full textThe Interacting Boson Model (IBM) with broken pairs is extended to include the simultaneous alignment of one neutron and one proton pair. The extended version can be applied in the description of high-spin dipole bands in spherical and transitional nuclei. The model is illustrated on the example of 13660Nd: a consistent theoretical interpretation is found for all observed bands, including the two dipole high-spin structures based on the (oh11/2)2 (àh11/2)2 configuration

No full textIBFM Description of High-Spin States in N=74 Isotones
No full textThe Interacting Boson Model (IBM) can be extended to the description of collective bands built on two-, or four-quasiparticle states, if the model Hamiltonian allows for the change of one, or two bosons into quasiparticle pairs. An IBM version including up to two broken pairs is here applied to transitional nuclei with neutron number N = 74, with emphasis on negative-parity dipole bands, for which preliminary results on electromagnetic transition strengths are also presente
Complex mapping of words and gestures in TED Talks
No full textThe article explores the interdependence of the verbal and the physically embodied – here gesture-related – subsystems in the creation of meaning in a sample of TED Talks (www.ted.com), an increasingly popular genre for scientific popularization largely exploited in education. My goal is to identify and illustrate possible indices of complexity in the mapping of words with gestures, thus paving the way for a better understanding of the role of different semiotic resources in the talks and, ultimately, contributing to the development of multimodal literacy. In fact, the hybrid nature of the genre legitimises a holistic approach to the analysis of its discourse as a complex multisemiotic system. Multimodal ensembles (Kress 2003; 2009; 2010) are viewed as a special case of complex systems, and modal density (Norris 2009) and modal coherence (cf. Valeiras Jurado 2017) as indices of complexity therein. Data description is based on multimodal transcription through an integrated method (Lazaraton 2004), which makes it possible to advance hypotheses about the interpretation of different gestures (NcNeill 1992). Indeed, several gestures in the talks under analysis complement verbal information in no redundant ways and appear to serve various functions on different discourse levels, both locally and more globally, and in more or less predictable (hence more complex, context-dependent) ways
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Pull up the drawbridge? Conventionality and creativity in British political discourse
No full textThe paper investigates a metaphor which is recently being widely employed in relation to two of the main issues of the moment, i.e. im¬migration and Brexit: pull up the drawbridge. The public discussions about the EU and immigration are couched, like all political discourse, in metaphors, and this paper corroborates the assumption that today the new political divide is no longer left versus right but drawbridge up ver¬sus drawbridge down, and the contest that matters now is mostly open against closed. Indeed, politicians have always relied on the conceptual metaphor of ‘England as a fortress’, with a drawbridge which could be pulled up, if necessary. Immigration is regarded as one of the main caus¬es that pushed Britain toward Brexit, and even though the migration pan¬ic has been shaking Europe for more than a decade, recent events show that politicians are turning the ‘cosmic fear’ that is haunting the Western world into ‘official fear’: fear of losing control, fear of losing borders and national sovereignty, fear of the EU, of ‘an ever closer Union’, and now after the Brexit outcome, fear of a leap into the unknown, and of this one-way ticket to no clear destination. The only way out of this crisis of humanity and out of the anxiety we experience in the face of uncertainty is ‘pull up the drawbridge and retreat from the world’. The study relies on a large corpus of politicians’ speeches from Tony Blair’s to Theresa May’s government and is an attempt to analyse how conventional or how creative are the linguistic techniques they use to refer to them
The symbolic articulation of other-ness: A corpus-assisted analysis of Wide Sargasso Sea
No full textThis contribution presents a corpus-assisted analysis of Jean Rhys’ Wide Sargasso Sea (1966), a postcolonial prequel to Jane Eyre. The study is part of a larger research project on the role of corpus linguistics in Ruqaiya Hasan’s model forthe study of literature, Systemic Socio-Semantic Stylistics (Hasan 1989, 2007). Combining quantitative findings from corpus-assisted investigation with qualitative considerations, it focuses on the Appraisal patterns (Martin and White 2005) involving the adjective 'white' and its collocates in Rhys’ novel, and examines their role in symbolically articulating part of the text’s deepest meaning, or theme (Hasan 1989: 97-98)
