The diploma thesis deals with negation in Spanish, especially lexical negation and negative prefixes. It is divided into two parts: the first one is theoretical which is followed by a practical one, which contains its own research. The aim of the first part is to genereally define negation from the perspective of various disciplines and to characterize the means that are used to create the negative (in Spanish and Czech). The greatest emphasis is placed on word- formation negation, that is why basic word-forming processes are defined here. In the theoretical part, the greatest attention is paid to prefixation: basic categories of prefixes are described with emphasis on negative prefixes. The second part focuses on the research which is based on the work with the language corpus and subsequently the questionnaire, which was created for the purpose of the work. The aim of the practical part is to discover some specifics in the behaviour of individual negative prefixes (a-, des-, in-, anti- and contra-) and their possible interchangeability. Subsequently conclusions are drawn from this part, following the theoretical part and completing the overall view of lexical negation in Spanish.

Police officers experience stress from operational and organizational demands which are extrinsic in nature. Officers may also experience stress from not being able to attain their personal goals for becoming a police officer, which is referred to as goal negation. The purpose of this mixed model, exploratory study was to examine if stress from goal negation is an intrinsic moderating factor of police officers' overall experience of career-related stress that may be adding to the health risks of the profession. The framework for the study included the concept of goal negation and the theory of operational and organizational or intrinsic and extrinsic stressors. The study was conducted in a Southern state with a sample of 52 acting police officers with 1 to 6 years of field experience. Two online survey questionnaires were modified from McCreary and Thompson's PSQ-Org and PSQ-Op and used to measure organizational and operational stressors. In-depth interviews added to the exploration of the lived experiences of officers in assessing their personal goal attainment. Results from the exploratory multivariate factor analysis of variance (MANOVA) of operational and organizational survey scores indicated that goal negation played a significant role in moderating stress for police officers in their duties. In addition, the content analysis of the interviews revealed a theme of conflict between police officers' personal goals and the operational role of police in the public context today. The results of this study will contribute to social change by informing police agencies, police training centers, and mental health treatment facilities of possible job sources of stress for new hires and career-oriented police personnel.

In the Arabic-speaking world, sociopolitical upheaval, extended conflict and population displacement have triggered extensive contact between mutually intelligible varieties of the language. Notwithstanding these developments, Arabic sociolinguistic research on dialect contact settings remains limited to certain well-documented areas (e.g., Al-Wer 2020), with markedly less research targeting other locales believed to be highly propitious to convergent change, such as the long-term contact situation in Lebanon involving Lebanese and Palestinian Arabic (Fityan 1981; Hennessey 2011). Furthermore, few studies are embedded in a (comparative) variationist sociolinguistic framework (Owens 2013), and even fewer studies are articulated from a socio-historical perspective incorporating diachronic data sources with which to better understand the process of language change in Arabic (Owens 2013). Much previous research on Arabic dialects is also based on investigations of phonological variation (Al-Wer and de Jong 2018), with correspondingly less attention paid to (morpho-)syntactic variation (Choueiri 2019). The present study aims to address existing lacunae in the research literature by investigating the outcomes of dialect contact in Beirut between Palestinian Arabic (PA), the minority variety, and Lebanese Arabic (LA), the majority variety. Drawing on the framework of comparative variationist sociolinguistics (Poplack and Tagliamonte 2001) as well as research on dialect contact (Britain and Trudgill 2005), this study combines synchronic and diachronic data sources to compare three variables in LA and PA: a phonological variable, involving the word-medial raising of /a:/ to [e:] (e.g., [ka:n] alternating with [ke:n] 'he/it was'); and two morpho-syntactic variables: verbal negation and future temporal reference. The overarching aim of the research is to examine the extent to which PA shows evidence, as gauged from linguistic constraints on variant selection and variant repertoires, of becoming more structurally similar to LA in different linguistic components (Cheshire, Kerswill, and Williams 2005). The synchronic data come from 45 hours of spontaneous speech recorded in Beirut from 39 Palestinian and 27 Lebanese speakers stratified by age, sex, and level of education, generating 7,671 tokens representing the three targeted variables. A further 15,381 tokens of these three variables come from two diachronic datasets. The first is a sub-set of speech recordings from the Palestinian Oral History Archive, an online compendium of interviews with first-generation (older) Palestinians in Lebanon, recorded between the 1990s and early 2000s. The second diachronic dataset is the Lebanese Popular Theatre Corpus (LPTC), based on 34 televised plays dating from the 1960s and performed in colloquial LA. Results reveal that the [e:] variant, a stereotypical feature of LA, but not emblematic of PA spoken in Beirut (Hennessey 2011), is virtually absent from the speech of the older Palestinian generation in the synchronic and diachronic datasets, but it increases significantly in the speech of young (third-generation) Palestinian speakers, who replicate the linguistic conditioning of variant selection in LA. These results bolster the inference of contact-induced change in PA due to the influence of LA. With respect to verbal negation, the findings show that there is convergent change in terms of overall variant rates in this variable system in PA. Evidence suggests that this variable system is undergoing dialect levelling as a result of contact, with socially marked minority variants diminishing over time in the speech of educated Palestinians. The future temporal reference system, however, seems to be less amenable to contact-induced change, despite similarities in surface forms between LA and PA. Results indicate that this variable system is undergoing an internal change in PA independent of contact with LA, which is led by young, educated speakers, in line with what has been observed in PA spoken outside Lebanon (AbuAmsha 2016). Viewed in the aggregate, the results show that even though it is claimed that (morpho-) syntactic variables may be less susceptible to convergent change than phonological variables (Cheshire et al. 2005; Hinskens et al. 2005), we do not find a neat division between phonology and morpho-syntax. Word-medial imala is overtly commented on and explicitly identified by the targeted Palestinian speech community as a marker of Lebanese speech. Its iconic association with Lebanese speech patterns renders it particularly susceptible to long-term dialect accommodation for some Palestinians. Verbal negation is also subject to social evaluation, as gauged from explicit speaker meta-commentary, and socially marked exponents appear vulnerable to attrition over time. By contrast, the expression of the future temporal reference appears less socially indexical than the other variables and is not subject to normative commentary or overt correction. These differences implicate the social salience of the targeted variables as a key factor influencing their susceptibility to convergence. Situating the results in a wider perspective, the findings highlight the utility of the comparative variationist framework in elucidating the process of language change in spoken Arabic, especially in PA as spoken in Beirut, as well as in distinguishing contact-induced change from internally-motivated change. The results of this study indicate that the effects of dialect contact, and critically, the existence of contact-induced change cannot be fully understood without using a multi-faceted comparative approach incorporating horizontal and vertical comparisons. The results converge in demonstrating that an empirically accountable quantitative approach based on actual speech data is capable of transcending the limitations of alternative frameworks of analysis that have been used to investigate change in dialect contact scenarios in the Arabic-speaking world.

Das Ziel dieser Arbeit ist es die mathematische Theorie der Begriffsalgebren zu entwickeln. Wir betrachten dabei hauptsaechlich das Repraesentationsproblem dieser vor Kurzem eingefuehrten Strukturen. Motiviert durch die Suche nach einer geeigneten Negation sind die Begriffsalgebren entstanden. Sie sind nicht nur fuer die Philosophie oder die Wissensrepraesentation von Interesse, sondern auch fuer andere Felder, wie zum Beispiel Logik oder Linguistik. Das Problem Negationen geeignet einzufuehren, ist sicher eines der aeltesten der wissenschaftlichen oder philosophischen Gemeinschaft und erregt auch zur Zeit die Aufmerksamkeit vieler Wissenschaftler. Verschiedene Typen von Logik (die sich sehr stark durch die eigefuehrte Negation unterscheiden) unterstreichen die Wichtigkeit dieser Untersuchungen. In dieser Arbeit beschaeftigen wir uns hauptsaechlich mit der kontextuellen Logik, eine Herangehensweise der Formalen Begriffsanalyse, basierend auf der Idee, den Begriff als Einheit des Denkens aufzufassen. / The aim of this investigation is to develop a mathematical theory of concept algebras. We mainly consider the representation problem for this recently introduced class of structures. Motivated by the search of a "negation" on formal concepts, "concept algebras" are of considerable interest not only in Philosophy or Knowledge Representation, but also in other fields as Logic or Linguistics. The problem of negation is surely one of the oldest problems of the scientific and philosophic community, and still attracts the attention of many researchers. Various types of Logic (defined according to the behaviour of the corresponding negation) can attest this affirmation. In this thesis we focus on "Contextual Logic", a Formal Concept Analysis approach, based on concepts as units of thought.

在1960年為《理性與革命》寫的序言中，馬庫塞就曾提過所謂的「既定事實的力量」(the authority of established fact)，他認為「這是一種壓迫的力量」。 馬庫塞在其著作當中已多次提及所謂「既定的現實」(the established reality)，所意指的不外乎是身處於先進工業社會中的個體受到既定體制的壓迫(oppression)與制約，換言之，先進工業社會充滿著非解放的因素。 「現今，自由(freedom)與奴役(servitude)的結合變得『理所當然』(“natural”)，它已成為進步的一種手段(a vehicle of progress)。」此一論點馬庫塞在《愛欲與文明》一書中已提出，並在《單向度的人》一書中更充分地開展。 《單向度的人》的主要論點在於整體社會的意識受制於後期資本主義社會的結構，致使人們的思維無法覺醒，「現實即是合理」已經成為社會的正常看法，也就是大多數人皆依循此種模式過生活，而不去變革現狀(the status quo)。因為這一種消費與生產已形成人們的固定思維模式，即單向度的思維，由於人們不再反省現實社會的單向度現象，因此人們無法從單向度的現象中解放出來，大多數人仍處於不自覺的狀態，受到操控，社會中的成員共同架構出壓迫性的思維方式(oppressive mode of thinking)，「人的意識受制於社會的存在」，人心加重現實的趨勢致使「單向度」(one-dimensionality)的態勢逐步成形。

La nouvelle « Bartleby The Scrivener. A Story of Wall-Street » pose des questions de lecture et d’interprétation littéraire. Grâce à des approches ayant le discours pour objet ou moyen de connaissance (rhétorique, étymologie, psychanalyse, pragmatique) de même qu’aux écrits de Herman Melville, il s’agit de cerner ce que représente Bartleby, qualifié d’« unaccountable » (inexplicable). Ce mot organise l’étude. Entier ou décomposé en morphèmes, dans une première partie, il met en évidence des univers de sens où Bartleby se montre marginal et court-circuite les systèmes : l’univers du langage (« unaccountable » : inénarrable), celui de la loi (« count » : chef d’accusation) et celui des chiffres (« account, count » : compte, compter). Une seconde partie rattache les pistes de lecture implicites ainsi dégagées aux thématiques de l’« inexplicable », explicites dans le texte, permettant une interprétation touchant l’univers des lettres, leur pérennité et leur circulation par le biais de la lecture et de l’interprétation. / The short story “Bartleby The Scrivener. A Story of Wall Street” raises questions about reading and literary interpretation. Using approaches where language is the object or means of knowledge (rhetoric, etymology, psychoanalysis, pragmatics) along with writings from Herman Melville, we aim to consider what is represented by Bartleby, who is often described as unaccountable. This very word structures the study. The first part of the thesis examines this word, taken as a whole or broken down into morphemes, as conveying universes of meaning in which Bartleby appears as marginal, short-circuiting diverse systems: the universe of language (unaccountable), the universe of the law (count) and the universe of the numbers (account, count). The second part links the implicit threads of meaning thus revealed to the theme of the strange and unexplainable (unaccountable), explicit in the text, allowing for interpretations bearing on the world of literary texts, their conveyance and circulation through reading and interpretation.

Notre thèse s'adresse aux francophones qui veulent apprendre l'arabe, son lexique, sa syntaxe et sa sémantique. L'une des difficultés majeures que rencontre l'apprenant dès qu'il entre en contact avec notre langue, est le traitement des aspects et des temps, localement et dans l'ensemble de l'énoncé. Dans le cadre, d'une description des aspects et des temps nous sommes contraints de faire une étude générale de la morphologie verbale et des catégories grammaticales de l'arabe standard. Mais nous devons aussi travailler sur les mêmes structures en français qui est la langue source de nos apprenants afin de mettre en regard les deux systèmes linguistiques. Le second visage de ce travail est nettement plus technologique. Nous avons insisté sur les interfaces des leçons que nous présentons sur Internet afin de montrer comment elles participent de façon active à la compréhension des contenus par les apprenants. / Our thesis is intended for francophones wishing to learn Arab, its lexicon, its syntax and its semantics. One of the main difficulties which the learner encounters as soon as he enters into contact with our language is the treatment of aspects and of tenses, bath locally and throughout the whole statement or text. The description of aspects and tenses requires us to make a general study of the verbal morphology of the grammatical structures of standard Arab. But we are also brought to work on the same structures in French which is the source language of the learners in order to make a comparative study of the two language-systems. The second face of this work is considerab1y more technical. We have insisted on the interfaces of the lessons that we present on Internet in order to show how they contribute in an active way to the understanding of the contents by the learners
