Essiivi on suomen kielen sijamuoto, jota käytetään nykykielessä erilaisten olotilojen ilmaisemiseen (Hän on opettajana ~ sairaana). Se on taustaltaan lokatiivi, jonka paikanilmaisutehtävä näkyy edelleen erilaisissa kiteytymissä (kotona, luona). Essiivi kuuluu myös ajankohdanilmaisujärjestelmään (lauantaina, ensi vuotena). Tässä tutkimuksessa kuvaan essiivisijan käyttöä erityisesti olotilan ilmaisemisen näkökulmasta. Kiinnitän huomiota sijan merkitykseen ja pyrin tarkentamaan sen lauseopillista kuvausta hyödyntämällä yleislingvistis-kielitypologisia olotilanilmausten kategoriointitapoja. Tutkimukseni aineisto on kolmijakoinen. Pääaineistonani on Lauseopin arkisto, jota koskevan haun tuloksena olen saanut 9096 essiivisijaisen sanan sisältävää lauseketta virkekonteksteineen. Täydennän tätä aineistoa käytöstä poimituilla esimerkeillä ja intuitioon pohjautuvilla ns. selvillä tapauksilla. Tutkimusmenetelmänä on pääosin aineiston kvalitatiivinen tarkastelu, mutta tarkastelen essiiviä myös teoreettisemmin sääntöjärjestelmän näkökulmasta. Tärkeimpänä lähtökohtanani on tuottaa tutkimustietoa, joka kykenee käymään vuoropuhelua kielitypologisen tutkimuksen kanssa siten, että tutkimus kuitenkin tapahtuu yksittäiskielen ehdoilla. Erityisesti semantiikan kuvauksessa tarkastelutapani on kognitiivisen kielitieteen mukaisesti orientoitunut. Essiivin tehtävänä on pelkistetyssä nominaalilauseessa ilmaista olotilan tilapäisyyttä ja muutoksellisuutta, kun taas merkitystä kantavan verbin yhteydessä essiivisijainen olotilan ilmaus saa usein muita merkityksiä ja voi ilmaista myös vaihtoehtoisen tai tilanteen syynä olevan olotilan. Aspektinäkökulmasta essiivi tuo tilaan toimin¬nallisia piirteitä, ja se myös muodostaa selvästi omanlaisensa reviirin suhteessa muihin olotilaa ja sen lähimerkityksiä ilmaiseviin kieli- ja johto-opin kategorioihin. Syntaktisen luokittelun näkökulmasta essiivisijaiset predikoivat olotilanilmaukset jakautuvat kolmeen pääryhmään sen perusteella, millainen niiden suhde lauseen predikaattiin on. Ne voivat toimia kopulalauseen nominaalipredikaatteina, merkitystä kantavien verbien täydennyksinä ja sekundaarisina predikaatteina, jotka ovat määritteitä. Lisäksi essiivisijaiset olotilan ilmaukset voivat toimia predikoimattomina lauseadverbiaaleina. Tutkimus on essiivisijan laaja aineistopohjainen kuvaus, joka osoittaa, että yleislingvistis-kielitypologinen lähestymistapa sopii suomen essiivin kuvaukseen. Alakategorioinnissa joudutaan kuitenkin turvautumaan semantiikkaan. Myös pääkategorioiden jatkumomaisuus on hyväksyttävä. Tulosten perusteella on mahdollista käydä keskustelua siitä, olisiko predikoivien lauseenjäsenten syntaktista luokittelua mahdollista uudistaa. Lisäksi tutkimus avaa uusia kysymyksiä tutkittavaksi erityisesti sijojen käyttöä vertailevasta näkökulmasta.

Sequences of timestamped events are currently being generated across nearly every domain of data analytics, from e-commerce web logging to electronic health records used by doctors and medical researchers. Every day, this data type is reviewed by humans who apply statistical tests, hoping to learn everything they can about how these processes work, why they break, and how they can be improved upon. To further uncover how these processes work the way they do, researchers often compare two groups, or cohorts, of event sequences to find the differences and similarities between outcomes and processes. With temporal event sequence data, this task is complex because of the variety of ways single events and sequences of events can differ between the two cohorts of records: the structure of the event sequences (e.g., event order, co-occurring events, or frequencies of events), the attributes about the events and records (e.g., gender of a patient), or metrics about the timestamps themselves (e.g., duration of an event). Running statistical tests to cover all these cases and determining which results are significant becomes cumbersome. Current visual analytics tools for comparing groups of event sequences emphasize a purely statistical or purely visual approach for comparison. Visual analytics tools leverage humans' ability to easily see patterns and anomalies that they were not expecting, but is limited by uncertainty in findings. Statistical tools emphasize finding significant differences in the data, but often requires researchers have a concrete question and doesn't facilitate more general exploration of the data. Combining visual analytics tools with statistical methods leverages the benefits of both approaches for quicker and easier insight discovery. Integrating statistics into a visualization tool presents many challenges on the frontend (e.g., displaying the results of many different metrics concisely) and in the backend (e.g., scalability challenges with running various metrics on multi-dimensional data at once). I begin by exploring the problem of comparing cohorts of event sequences and understanding the questions that analysts commonly ask in this task. From there, I demonstrate that combining automated statistics with an interactive user interface amplifies the benefits of both types of tools, thereby enabling analysts to conduct quicker and easier data exploration, hypothesis generation, and insight discovery. The direct contributions of this dissertation are: (1) a taxonomy of metrics for comparing cohorts of temporal event sequences, (2) a statistical framework for exploratory data analysis with a method I refer to as high-volume hypothesis testing (HVHT), (3) a family of visualizations and guidelines for interaction techniques that are useful for understanding and parsing the results, and (4) a user study, five long-term case studies, and five short-term case studies which demonstrate the utility and impact of these methods in various domains: four in the medical domain, one in web log analysis, two in education, and one each in social networks, sports analytics, and security. My dissertation contributes an understanding of how cohorts of temporal event sequences are commonly compared and the difficulties associated with applying and parsing the results of these metrics. It also contributes a set of visualizations, algorithms, and design guidelines for balancing automated statistics with user-driven analysis to guide users to significant, distinguishing features between cohorts. This work opens avenues for future research in comparing two or more groups of temporal event sequences, opening traditional machine learning and data mining techniques to user interaction, and extending the principles found in this dissertation to data types beyond temporal event sequences.

One of the prominent questions in modern psycholinguistics is the relationship between the grammar and the parser. Within the approach of Generative Grammar, this issue has been investigated in terms of the role that Principles of Universal Grammar may play in language processing. The aim of this research experiment is to investigate this topic. Specifically, this experiment aims to test whether the Minimal Structure Principle (MSP) plays a role in the processing of Preposition-Stranding versus Pied-Piped Constructions. This investigation is made with a self-paced reading task, an on-line processing test that measures participants’ unconscious reaction to language stimuli. Monolingual English speakers’ reading times of sentences with Preposition-Stranding and Pied-Piped Constructions are compared. Results indicate that neither construction has greater processing costs, suggesting that factors other than the MSP are active during language processing.

Alfonso de Cartagena (1385-1456), possibly the most representative figure of the courtly, political and cultural dimension built around Juan II, was the third son of the famous convert Pablo de Santa Maria, Burgos’ rabbi and, later on, bishop of that same town. He started his career as governor of Cartagena’s cathedral, afterwards he was named dean of Santiago and Segovia, canon of Burgos and, after his father’s death, bishop of Burgos. Alternatively, he played a vital role in Castile’s national and international politics, as an ambassador in Portugal’s court, at Basel’s council and before Poland’s and Germany’s kings. His work, written both in Latin and Romance, either as an historian, treatise writer, theologist or translator, is quite broad; his literary connections were strong either with Italian humanists or with those who were fond of the language arts from Spain. The first part of this Thesis seeks to provide a wide enough perspective of the author, for which we place the emphasis on the most distinctive aspects of his life. Therefore, we divided the introduction in three sections: a biographical overview, his work and, last, a study on the Memoriale uirtutum itself. Thus, regarding the first aspect, we focus on the course of his life (§1.1), where we can highlight his university education, which isn’t restricted to his training as a jurist, but we also observe that his mental vitality takes him to develop certain inquisitiveness for Moral Philosophy or Latin, which leads him to study Grammar and Rhetoric; this would allow the influence of studia humanitatis to emerge, although he never got to learn the Greek language, as we can deduce from the epistolary confrontation between him and Leonardo Bruni. We also focus on the significance of his Jewish past, upon the defence of the converts during the massacre experienced in the XVth century (§1.2), and on his presence at Basel’s council (§1.3). Despite the fact that his work as a diplomat begins during the missions in Portugal as an emissary of king Juan II, he will get recognition owing to his legation in Basel, not only among the European ecclesiastics, but also among the scholars from Italy; the importance of Basel’s council in Cartagena’s life goes beyond his official work there, either as defending the Castilian interests, or as an active member of the purely conciliar functions, since it also had a huge impact in his intellectual growth. During this time period, Cartagena establishes a friendship with Pizzolpaso, Bishop of Milan, writer, humanist, and friend of Leonardo Bruni. As a result of this type of relationship with men of such high cultural standard, he re-awakens the study of the Classical antiquity among his contemporaries, developing a huge interest in the Greco-Roman masterpieces, which will bring him closely to the highly-regarded Spanish humanists of the XVIth century...
