Question: Who is the Russian scholar, whose interpretation of metalinguistics, Jacob L Mey describes in his book, Trends in Lingusistics?

Context paragraphs:
Anaphora (linguistics): In linguistics, anaphora ( ) is the use of an expression whose interpretation depends upon another expression in context (its antecedent or postcedent).  In a narrower sense, anaphora is the use of an expression that depends specifically upon an antecedent expression and thus is contrasted with cataphora, which is the use of an expression that depends upon a postcedent expression.  The anaphoric (referring) term is called an anaphor.  For example, in the sentence "Sally arrived, but nobody saw her", the pronoun "her" is an anaphor, referring back to the antecedent "Sally".  In the sentence "Before her arrival, nobody saw Sally", the pronoun "her" refers forward to the postcedent "Sally", so "her" is now a "cataphor" (and an anaphor in the broader, but not the narrower, sense).  Usually, an anaphoric expression is a proform or some other kind of deictic (contextually-dependent) expression.  Both anaphora and cataphora are species of endophora, referring to something mentioned elsewhere in a dialog or text.

Boolean algebras canonically defined: Boolean algebra is a mathematically rich branch of abstract algebra.  Just as group theory deals with groups, and linear algebra with vector spaces, Boolean algebras are models of the equational theory of the two values 0 and 1 (whose interpretation need not be numerical).  Common to Boolean algebras, groups, and vector spaces is the notion of an algebraic structure, a set closed under zero or more operations satisfying certain equations.

New Chronology (Fomenko): The New Chronology is a pseudohistorical theory which argues that the conventional chronology of Middle Eastern and European history is fundamentally flawed, and that events attributed to the civilizations of the Roman Empire, Ancient Greece and Ancient Egypt actually occurred during the Middle Ages, more than a thousand years later.  The central concepts of the New Chronology are derived from the ideas of Russian scholar Nikolai Morozov (1854–1946), although work by French scholar Jean Hardouin (1646–1729) can be viewed as an earlier predecessor.  However, the New Chronology is most commonly associated with Russian mathematician Anatoly Fomenko (born 1945), although published works on the subject are actually a collaboration between Fomenko and several other mathematicians.  The concept is most fully explained in "History: Fiction or Science?" , originally published in Russian.

Filippo Coletti: Filippo Coletti (11 May 1811 – 13 June 1894) was an Italian baritone associated with Giuseppe Verdi.  Coletti created two Verdi roles: Gusmano in "Alzira" and Francesco in "I Masnadieri".  Verdi revised the role of Germont in La traviata for Coletti, whose interpretation re-defined the role as it is known today.  Filippo Coletti was, with Antonio Tamburini (1800–1876) and Giorgio Ronconi (1810–1890), one of the three leading baritones of 19th century Italy, an early model of a 'Verdi baritone'.

Anthony Brown (musician): Anthony Brown is an American jazz percussionist, drummer, composer, and bandleader, and ethnomusicologist.  He is the son of a Choctaw and African-American father and a Japanese mother.  Long associated with the Asian-American jazz movement, he specializes in the juxtaposition of American and Asian instruments and styles in his compositions and arrangements.  Brown leads a cross-cultural ensemble, the Asian American Orchestra, whose interpretation of Duke Ellington's "Far East Suite" was nominated for a 2000 Grammy Award.  He has also performed with Jon Jang and Mark Izu.

Journal of Pragmatics: The Journal of Pragmatics is a peer-reviewed academic journal published by Elsevier.  The "Journal of Pragmatics" was established in 1977 by Jacob L. Mey (at that time Odense University) and Hartmut Haberland (Roskilde University).  The journal has an impact factor of 1.118.  The editors in chief are Neal R. Norrick (Saarland University) and Michael Haugh (The University of Queensland).

Metalinguistics: Metalinguistics is the branch of linguistics that studies language and its relationship to other cultural behaviors.  It is the study of dialogue relationships between units of speech communication as manifestations and enactments of co-existence.  Jacob L. Mey in his book, "Trends in Linguistics", describes Mikhail Bakhtin's interpretation of metalinguistics as "encompassing the life history of a speech community, with an orientation toward a study of large events in the speech life of people and embody changes in various cultures and ages."

Mikhail Bakhtin: Mikhail Mikhailovich Bakhtin ( ; Russian: Михаи́л Миха́йлович Бахти́н , ] ; 17 November [O.S. 5 November] 1895 – 7 March 1975) was a Russian philosopher, literary critic, semiotician and scholar who worked on literary theory, ethics, and the philosophy of language.  His writings, on a variety of subjects, inspired scholars working in a number of different traditions (Marxism, semiotics, structuralism, religious criticism) and in disciplines as diverse as literary criticism, history, philosophy, sociology, anthropology and psychology.  Although Bakhtin was active in the debates on aesthetics and literature that took place in the Soviet Union in the 1920s, his distinctive position did not become well known until he was rediscovered by Russian scholars in the 1960s.

Felicity conditions: In J. L. Austin's formulation of speech act theory, a performative utterance is neither true nor false, but can instead be deemed "felicitous" or "infelicitous" according to a set of conditions whose interpretation differs depending on whether the utterance in question is a declaration ("I sentence you to death"), a request ("I ask that you stop doing that") or a warning ("I warn you not to jump off the roof").

Relative clause: A relative clause is a kind of subordinate clause that contains an element whose interpretation is provided by an antecedent on which the subordinate clause is grammatically dependent; that is, there is an anaphora relation between the relativized element in the relative clause and the antecedent on which it depends.
