abstract: This study explores the topic of Discourse Markers from an Interdisciplinary perspective. Applying the frameworks of Speech Act Theory, Syntax, Conversation Analysis, and Discourse Analysis, to empirical data, it answers the following important questions. What specific types of Speech Actions are performed in everyday Utterances? What Syntactic Mood & Clause Type is used to perform the various Speech Actions? What Discourse Markers occur in the Left-Periphery of the Clause? What Meaning-Functions do Discourse Markers perform? What interactions do Discourse Markers have with the various types of Speech Actions and with the Clause Type with which they are expressed? The results of this study contributed valuable insights to each of the aforementioned fields individually, as well as to the study of human language in general. Among these contributions are the following: Searle’s Taxonomy of Speech Acts was refined by dividing Representatives into Informing and Opinionating and Directives were divided into Commanding and Inquiring. The frequencies of the various Speech Acts relative to each other was identified. Furthermore, 79 distinct and specific Speech Actions were identified. The Speech Act type as well as the Clause Types with which they are expressed were identified. Among the many insights with respect to the interactions between the Speech Action Types and the Clause types with which they are expressed were each of the major Clause Types perform many different Speech Actions that are in addition to those normally attributed to them. Many of the particular Speech Acts are performed via various of the different Clause Types. The Indicative Clause type has the ability to perform most, if not all of the Speech Actions performed by all of the other Clause types. The 200 most frequently-occurring Left-Periphery Elements were identified and observations regarding their Word Class and the Meaning-Functions they perform were identified. The Meaning-Functions of the 10 most frequently-occurring Discourse Markers were identified and defined. The interactions between these Discourse Markers and the Speech Actions to which they attach as well as the Clause Types with which they are expressed were identified, thus documenting empirically that Discourse Markers are intricately connected to the Clause. / Dissertation/Thesis / Doctoral Dissertation Linguistics and Applied Linguistics 2020

In Shakespeare’s Othello, Othello faces societal pressures of racism as he marries Senator Brabantio’s White daughter Desdemona. This creates the main plot, and the villain of the play, Iago, plots against him which leads to the destruction of Othello’s reputable character. Othello is transformed into a violent, murderous husband by Iago’s villainous ploy fueled by using racial slurs, and Othello’s final form matches the name his enemies assign him. Stripping Othello of his name and portraying him as “the Moor”, a term used to describe a category of Black persons viewed as barbaric, is a tactic used throughout time and is rooted in historical strategies for identity destruction and racism. The reader witnesses this tactic in a play written some 400 years in the past, but the problem still lingers in America where racism is commonly expressed through “Speech Acts”. Just a short time ago, Paul Robeson, a famous actor of Othello, faced these same problems while pursuing his spot on the stage. In consideration of today’s time, the movement “Say His Name” started following the death of George Floyd only two years ago, and this signifies the persistence of racism alongside the importance of names. Using slurs or refusing to use a person’s rightful name is a form of racial identity destruction witnessed from Shakespeare’s time, to Paul Robeson’s portrayal of the character, and into America’s now as the phrase “Say His Name” has become a staple in the fight against police brutality on Black persons in America.

This essay examines Ukrainian President Volodymyr Zelensky’s tweets during the early phase of the conflict between Russia and Ukraine. The method is mixed with both quantitative and qualitative studies and is based on content analysis. The analysis reveals that Zelensky has actively utilized Twitter to convey messages to the global community during the war. This study aims to analyze Zelensky’s Twitter communication through the lens of speech act theory and specifically focuses on Searle´s classifications of speech acts. By examining the messages posted on the Twitter account @ZelenskyyUa during the specified timeframe, the study explores the types of speech acts used by Zelensky and their intended audience. The study contributes to an understanding of Zelensky’s Twitter communication strategies during times of crisis. Findings from the analysis show that Zelensky effectively utilizes Twitter to advocate, inform, and influence others, using concise messages to reach a wide audience swiftly. It also reveals that Zelensky's communication style aligns with intercultural factors, effectively conveying his messages to the intended audience.

Yes / This paper presents a critical evaluation framework for a linguistically orientated conversational software agent (CSA) (Panesar, 2017). The CSA prototype investigates the integration, intersection and interface of the language, knowledge, and speech act constructions (SAC) based on a grammatical object (Nolan, 2014), and the sub-­‐model of belief, desires and intention (BDI) (Rao and Georgeff, 1995) and dialogue management (DM) for natural language processing (NLP). A long-­‐standing issue within NLP CSA systems is refining the accuracy of interpretation to provide realistic dialogue to support the human-­‐to-­‐computer communication. This prototype constitutes three phase models: (1) a linguistic model based on a functional linguistic theory – Role and Reference Grammar (RRG) (Van Valin Jr, 2005); (2) Agent Cognitive Model with two inner models: (a) knowledge representation model employing conceptual graphs serialised to Resource Description Framework (RDF); (b) a planning model underpinned by BDI concepts (Wooldridge, 2013) and intentionality (Searle, 1983) and rational interaction (Cohen and Levesque, 1990); and (3) a dialogue model employing common ground (Stalnaker, 2002). The evaluation approach for this Java-­‐based prototype and its phase models is a multi-­‐approach driven by grammatical testing (English language utterances), software engineering and agent practice. A set of evaluation criteria are grouped per phase model, and the testing framework aims to test the interface, intersection and integration of all phase models and their inner models. This multi-­‐approach encompasses checking performance both at internal processing, stages per model and post-­‐implementation assessments of the goals of RRG, and RRG based specifics tests. The empirical evaluations demonstrate that the CSA is a proof-­‐of-­‐concept, demonstrating RRG’s fitness for purpose for describing, and explaining phenomena, language processing and knowledge, and computational adequacy. Contrastingly, evaluations identify the complexity of lower level computational mappings of NL – agent to ontology with semantic gaps, and further addressed by a lexical bridging consideration (Panesar, 2017).

In the current ‘Age of Apology’, public apologies have become everyday occurrences; from corporate CEOs to Hollywood celebrities to political figures, the adage of ‘never apologize, never explain’ has been eschewed in favour of ‘always apologize, always explain’. In a society where news travels at the speed of the internet, and content can go ‘viral’ in hours, there are new pressures for all public figures to apologize when things go wrong. These public apologies are available for public consumption almost immediately after an offense, released through mainstream media (e.g. broadcast news, physical/online newspapers) or, as is becoming more frequent, over social media (i.e. Twitter, Facebook, and Instagram). Some researchers (e.g. Kampf, 2009; Thaler, 2012) have suggested that public apologies are not true apologies as defined by Speech Act theory – that they may serve another social function, but not to apologize. Such ‘fauxpologies’ are made without meeting the traditional felicity conditions for the speech act of apology (Ogiermann, 2009). If this is the case, what makes a public apology (in)felicitous? The aim of this thesis is to describe what makes a public apology felicitous. I present a critical analysis of the discourse strategies used in three types of public apologies – corporate, celebrity, and historical political – examining how these discursive strategies are used according to varying contextual factors using Critical Discourse Analysis and Speech Act theory as a framework. To counter the claim that the discourse strategies used in public apology do not meet the felicity conditions for the speech act of apology, I present evidence that, despite using some non-apology strategies, many public apologies are felicitous. However, I argue for the adoption of a revised set of felicity conditions as laid out by Murphy (2014, 2015), which can properly encompass public apology as a performative speech act. This study also extends the framework of semantic formulae previously used in apology analysis (Blum-Kulka & Olshtain, 1984; Olshtain & Cohen, 1983) to include ‘fauxpology’ strategies particularly useful in examining public apologies, which provides a more robust description of how public apologies are performed. / Thesis / Master of Science (MSc)

This paper seeks to explore novel perspectives on securitization by examining how Iran’s involvement in the Yemeni conflict since 2014 has been securitized by Saudi, US and Iranian political elites. By combining Copenhagen School securitization theory with Carol Lee Bacchi’s WPR (What’s the Problem Represented to Be?) framework for discourse analysis, this study demonstrates how elements of speech acts which are assumed, implicit, unproblematized or “silent” can contribute to securitization. The analysis finds that statements by Saudi and US political elites consistently represent Iran as a security threat without addressing the complexities of internal Yemeni dynamics. At times, it is assumed that the audience accepts and understands why Iranian involvement is inherently problematic. When the nature of the threat posed by AnsarAllah is discussed in detail, the Saudi perception of Iran’s involvement implicitly becomes a prerequisite for AnsarAllah’s perceived agency and operative capabilities. In accepting Saudi Arabia’s securitizing moves, US political elites reproduce this narrative, despite contradictory scholarly conclusions about Iranian involvement. This contributes to securitization by leaving assumptions about Iran and its role in Yemen unproblematized. The failure to address Iran’s shifting rhetoric also allows for the same narrative to be reproduced by the US, reinforcing the understanding of Iran as an inherently destabilizing force.

Abstract The American president’s serving period always begin with an iconic inaugural address. It is a function wherein the president can unify the audience, ratify the ceremony, and present his political and administrative direction for his term. Promises are a vital rhetorical tool and strategy at the president’s disposal; however, they can also be a demerit if used incorrectly. Within the discipline of pragmatics, promises are included in the category of the commissive speech act: an utterance which binds the speaker to a future course of action. The focus of the present study is what proportion commissive speech acts are used in relation to other speech acts by the four American presidents inaugurated in the 21st century in their inaugural addresses, as well as how these commissive speech acts are realized in terms of various pragmatic features (e.g., vagueness, deictic use, selfpositive representation, and implicature). The methodological approach adopted in thisstudy is both qualitative as well as quantitative in character. To reflect this, the study was operationalized through speech act analysis and political discourse analysis. The findingsshowcase that the presidents affiliated with the Republican party make use of commissive speech acts to a higher degree than their Democratic counterparts. Donald J. Trump appears as a clear outlier with an exuberant amount of commissive speech acts in comparison with the other three presidents. Furthermore, the findings point out that the most common strategy in how commissive speech acts were realised was to shape them as an assertion and using the inclusive deixis “we”. However, Joseph R. Biden diverged from this pattern. Instead, he used explicit promises featuring the individual deixis “I”. In addition, he often employed rhetorical vagueness which made his promises hard to measure if upheld or not.

The thesis is concerned with the definition of the speech politeness as a unique pragmatic system which is specific for each language community and which creates in speakers a pragmatic habitus or an abstract model for culturally speech behavior, manifested as a polite speech norm in geographically and time-limited context of a linguistic market. In the practical part, the thesis deals with the comparison of the language devices used by Czech and Spanish speakers to maintain the safe relationship with the addressee in order to achieve a successful socio-economic exchange. The study focuses on speech courtesy on one hand and comparison of two ethnolinguistic areas from the point of view of linguistics, pragmatics, sociology and cultural anthropology.
