The field of authorship determination, previously largely falling under the umbrella of literary analysis but recently becoming a large subfield of forensic linguistics, has grown substantially over the last two decades. As its body of research and its record of successful forensic application continue to grow, this growth is paralleled by the demand for its application. However, methods which have undergone rigorous testing to show their reliability and replicability, allowing them to meet the strict Daubert criteria put forth by the US court system, have not truly been established.

In this study, I set out to investigate how a list of parameters, many commonly used in the methodologies of previous researchers, would perform when used to test documents of bloggers from a sports blog, Winging It in Motown. Three prolific bloggers were chosen from the site, and a corpus of posts was created for each blogger which was then examined for each of the chosen parameters. One test document for each of the three bloggers which was not included in that blogger’s corpus was then chosen from the blog page, and these documents were examined for each of the parameters via the same methodologies as were used to examine the corpora. Once data for the corpora and all three test documents was obtained, the results were compared for similarity, and an author determination was made for each test document along each parameter.

The findings indicated that overall the parameters were quite unsuccessful in determining authorship for these test documents based on the author corpora developed for the study. Only two parameters successfully identified the authors of the test documents at a rate higher than chance, and the possibility exists that other factors may be driving these successful identifications, demanding further research to confirm their validity as parameters for the purpose of authorship work.

Abstract: This study investigates grades from 1980 to 2010 in English 102 at Arizona State University Tempe Campus to see if grade inflation has taken place. It concludes it has and then goes on to study the causes. The data was collected from existing data held in the archives of the Registrar's Office, collated into proper order and saved in proper numerical format for analysis. After analysis, the data was reviewed to establish whether or not as consumer demands rise, measured by student responses to evaluation questions, grade point averages rise as well, and whether demands for adequate performance in classrooms have declined. This study statistically analyzes students' final grades in ENG102 for thirty years and concludes that grade compression at the top of the grading scale exists. This study discusses the implications of that compression at length.

ABSTRACT There are many parts of speech and morphological items in a linguistic lexicon that may be optional in order to have a cohesive language with a complete range of expression. Negation is not one of them. Negation appears to be absolutely essential from a linguistic (and indeed, a psychological) point of view within any human language. Humans need to be able to say in some fashion "No" and to express our not doing things in various ways. During the discussions that appear in this thesis, I expound upon the historical changes that can be seen within three different language branches - North Germanic (with Gothic, Old Saxon, Old Norse, Swedish, and Icelandic), West Germanic (with English), and Celtic (with Welsh) - focusing on negation particles in particular and their position within these languages. I also examine how each of these chosen languages has seen negation shift over time in relation to Jespersen's negation cycle. Finally, I compare and contrast the results I see from these languages, demonstrating that they all three do follow a distinct negation cycle. I also explain how these three negation cycles are chronologically not in sync with one another and obviously all changed at different rates. This appears to be the case even within the different branches of the Germanic family.

This thesis explores the distribution of certain lexical items in Modern Standard Arabic (MSA) and their relationship with two linguistic phenomena, negative concord (NC) and negative polarity items (NPIs). The present study examines two central questions: the first question investigates whether or not MSA shows the patterns of negative concord languages. The second question concerns the distribution of N-words and NPIs in MSA, and in which environments they appear. To answer the research questions, the thesis uses the framework of generative grammar of Chomsky (1995) and The (Non)veridicality Approach by Giannakidou (1998, 2000, 2002). The data reveal that MSA shows the patterns of strict negative concord languages that are suggested by Giannakidou (2000) in the sense that the negative particle obligatorily co-occurs with the N-words which strengthen the degree of negation, and never lead to a double negation interpretation. Moreover, the data show that there is only one pure NPI which appears optionally in two environments, antiveridical and nonveridical environments, and it is disallowed in veridical environments. On the other hand, the investigated indefinite nouns show a mixed picture since they work differently from their counterparts in Arabic dialects. Their descendants in Arabic dialects appear as NPIs while they tend to be indefinite nouns rather than NPIs in MSA.

The primary topic of this dissertation is the grammaticalization of negation in three Sinitic language varieties: Hakka, Mandarin, and Southern Min. I discuss negative morphemes that are used under different modality or aspect contexts, including ability, volition, necessity, and perfectivity. Not only does this study examine Southern Min affirmative and negative pairs, but it also highlights the grammaticalization of negation and parametric differences in negation among the languages under investigation. This dissertation also covers the reanalysis of negatives into interrogatives. I approach the investigation of Southern Min negation from both synchronic and diachronic perspectives. I analyze corpus data in addition to data collected from fieldwork for the contemporary linguistic data. For my diachronic research of Chinese negation, I use historical texts and etymological dictionaries. Diachronically, many of the negative morphemes originate from full-fledged verbs and undergo an analogous grammaticalization process that consists of multiple stages of reanalysis from V to T (aspect; modality), and then T to C (interrogative; discourse). I explain this reanalysis, which involves head-to-head movement, using generative frameworks that combine a modified cartographic approach and the Minimalist Economy Principles. Synchronic data show that Southern Min affirmative modals are characterized by a certain morphological doubling. These doublings consist of two near synonyms used in sequence, resulting from the loss of features in a verb and a second verb added as a renewal. In the negation paradigm, some negatives project a negative phrase, while the others serve a dual function, occupying a modal/aspect head as well as a negative head. The latter system is gradually shifting to the former. This study uncovers evidence to counter the long-established paradigm, where negation is tied to its independent modality (abilitive, volitional and necessitive) or aspect (perfective and perfect). I observe a mismatch between the use of interrogatives and their modality/aspect and attribute this phenomenon to feature loss during their reanalysis from negatives to interrogatives. Results however show that consistency occurs in the grammaticalization of negation within Southern Min and intra-linguistically among the three Sinitic languages, and that parametric differences are found at the morphological level.
