Socio-pragmatic aspects of legal talk: police interviews and trial discourse
No full textProbably the most distinctive and most widespread linguistic feature of legal talk is the question – in both interrogative and declarative form and across a range of forensic settings: emergency calls to the police (Drew and Walker, this volume), police interviews (Aldridge; Benneworth; Haworth; this volume), lawyer and client interactions (Kozin 2008) and examination and cross-examination in court (Ehrlich; Felton Rosulek; Heffer; this volume). Lay interactants are largely controlled by and at the mercy of questions from professionals in dyadic legal encounters: a caller to a 999 or 911 number; an interviewee in a police interview; a witness in a trial. Any examination of legal talk must therefore involve an analysis of what is accomplished interactionally through the use of questions, including accounting for the effects of forensic questioning on the lay interactant. Syntactic and formal features of questioning are important aspects of any linguisticanalysis. However, our focus in this chapter is not merely on form, but on the pragmatic effects of legal talk in two important interactional contexts: police interviews and criminal trials. Pragmatic, social and inferential meaning-making is significant for both the institutional and the lay speaker, and what is done through questions and answers is particularly clear in cross-examination, as our first example (1) from Brennan (1994) illustrates. This syntactically complex cross-examination question is directed to a child; embedded clauses are shown by the use of square brackets (our addition)
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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Early transition metal complexes of carbene donors linked to cyclopentadienyl ring analogues or amidine/amidinate moieties
No full textThe new indenyl-functionalised NHC potassium salt, 1-[3-(4, 7-dimethylindenylpropyl]-3-(2,6-diisopropylphenyl)imidazol-2-ylidenepotassium, has been synthesised. Complexes oftitanium, zirconium and chromium containing this ligand and the two carbon bridge analogue,1-[2-(4,7-dimethylindenyl)ethyl]-3-(2,6-diisopropylphenyl)imidazol-2 ylidene potassium,have been synthesised and characterised by X-ray crystallographic techniques. The followingcomplexes were tested as catalysts for the oligomerisation of ethylene in the presence ofMAO: 3-(2,6-diisopropylphenyl)-1-[2-(4,7-dimethylindenyl)ethyl]-imidazol-2-ylidene(tertbutylimido)titanium chloride, 3-(2,6-diisopropylphenyl)-1-[3-(4,7-dimethylindenyl)propyl]imidazol-2-ylidene(tert-butylimido)titanium chloride, 3-(2,6-diisopropylphenyl)-1-[3-(4,7-dimethylindenyl)propyl]imidazol-2-ylidenezirconiumtrichloride, 3-(2,6-diisopropylphenyl)-1-[2-(4,7-dimethylindenyl)ethyl]imidazol-2-ylidenezirconium trichloride, 3-(2,6-Diisopropylphenyl)-1-[2-(4,7-dimethylindenyl)ethyl]-imidazol-2-ylidenechromium dichloride, 3-(2,6-diisopropylphenyl)-1-[3-(4,7-(dimethylindenyl)propyl]imidazol-2-ylidene chromium dichloride, 3-(2,6-diisopropylphenyl)-1-[3-(4,7-dimethylindenyl)propyl]-imidazol-2-ylidene chromium methyl chloride and 3-(2,6-diisopropylphenyl)-1-[2-(4,7-dimethylindenyl)ethyl]-imidazol-2-ylidenevanadium dichloride.The following alkyl chromium complexes containing 1-[2-(4,7-dimethylindenyl)ethyl]-3-(2,6-diisopropylphenyl)imidazol-2 ylidene potassium have also been synthesised: 3-(2,6-diisopropylphenyl)-1-[2-(4,7-dimethylindenyl)ethyl]-imidazol-2-ylidene chromium phenylchloride and 3-(2,6-diisopropyl-phenyl)-1-[2-(4, 7-dimethylindenyl)ethyl]-imidazol-2-ylidenechromium dibenzyl. Chromium cations have been synthesised using as starting materials thechromium alkyl complexes. The Cr(II) complex 3-(2,6-diisopropyl-phenyl)-1-[2-(4, 7-dimethylindenyl)ethyl]-imidazol-2-ylidene chromium monochloride and a partially oxidiseddimerised product were also isolated. 5-(2-chloroethyl)- 1, 2, 3, 4-tetramethylcyclopentadieneand 5-(3-chloropropyl) 1, 2, 3, 4-tetramethylcyclopentadiene were synthesised and isolated asgeminal isomers for the first time.The trialkyl chromium complex, tribenzyl chromium tris(tetrahydrofuran) was synthesisedand also it was used as starting material for the complexes di(benzyl)chromium bis(1, 3-diisopropylimidazol-2-ylindene) and tri(benzyl)chromium TACN. All complexes werecharacterised by X-ray crystallography.The imidazolium salt 3-(2.6-diisopropylphenyl)-1-[N, N-bis(2,6-diisopropylphenyl)acetamidyl] imidazolium chloride was synthesised and used as a precursorfor the synthesis of amidinate-functionalised NHC zirconium and amidine-functionalisedNHC silver complexes. Double deprotonation of 3-(2,6-diisopropylphenyl)-1-[N, N’-bis(2,6-diisopropylphenyl)acetamidyl] imidazolium chloride gave the amidinate-functionalised NHCligand, 3-(2.6-diisopropylphenyl)-1-[2-N, N’bis(2,6diisopropylphenylamidinate)ethyl]imidazol-2-ylidenepotassium. Titanium, zirconium andchromium complexes containing this ligand were synthesised and characterised by X-raycrystallographic techniques. Transmetallation of the amidine-functionalised NHC silvercomplex with [Rh(COD)Cl]2 and [Ir(COD)Cl]2 gave the corresponding species. Rh(amidinefunctionalisedNHC)(COD)Cl reacted with Na(BAr)4 (Ar = 3,5-CF3C6H3) to give the cationRh(amidine-functionalised NHC)(COD)]+[BAr4]-. These species were also characterised byX-ray diffraction techniques
