Through an examination of the processes and influences on the character of grey literature and its producers, this thesis explores the nature of archaeological investigation, how it is reported and the creation of archaeological data in England from 1990 to 2010 and the implications for future understanding of the English archaeological record. I intend to address broad research questions regarding grey literature and archaeology: What is grey literature? Who creates it and why? What is it meant for? Is it fit-for-purpose? My research objectives in studying grey literature reporting and archaeological fieldwork investigation in England are: •To explore the nature of archaeological grey literature reporting and its producers, the framework of its production and communication, and its impact on archaeological research and knowledge production; •To capture the developments and changes in English archaeological practice between 1990 and 2010 and their implications for the creation and understanding of the archaeological record; and •To consider potential future directions for archaeological fieldwork and reporting. I propose to achieve this using a combination of both quantitative and qualitative approaches including spatial analysis techniques, comparative analysis at a range of scales from England-wide to individual case study areas, and detailed analysis of the nature and actual content of grey literature reports alongside a characterisation of the many creators of grey literature reporting. This study will illustrate and explore the process of producing grey literature reporting as well as examining the end product itself - grey literature reports. This European Research Council funded DPhil research was undertaken within the context of the English Landscapes and Identities Project, which analyses change and continuity in the English Landscape from the middle Bronze Age (c.1500 BC) to the Domesday survey (c. AD 1086).

In dieser Arbeit untersuche ich aus einer typologischen Perspektive die Bedeutung von Tempus, Modalität und Aspekt (TMA) in Nafsan (South Efate), einer ozeanischen Sprache Vanuatus. Ich konzentriere mich auf die Bedeutung des perfektiven Aspekts und der Realis/Irrealis-Modalität in Nafsan und anderen ozeanischen Sprachen, als Fallstudien zur Untersuchung der sprach-übergreifenden Merkmale dieser TMA-Kategorien. Um ihre Bedeutungen in Nafsan zu analysieren, untersuche ich die Grammatik von Nafsan (Thieberger, 2006) und den Korpus von Thieberger (1995–2018), gefolgt von meiner Feldarbeit (Krajinovic, 2017b). Meine Analysen zeigen, dass Perfekt in Nafsan alle Funktionen hat, die für das Perfekt im Englischen typisch sind, mit Ausnahme der zusätzlichen Bedeutung von Zustandsänderungen. Die Verwendung des Nafsan-Perfekts liefert einen Beitrag zu der Debatte über die sprachübergreifende Gültigkeit von Iamitive, definiert durch die Bedeutung von Zustandsänderungen (Olsson, 2013). Basierend auf den Daten aus Nafsan und anderen ozeanischen Sprachen zeige ich, dass die von Klein (1994) vorgeschlagene semantische Definition des Perfekts ausreichend ist, um zusätzliche Funktionen des Perfekts zu berücksichtigen, ohne eine neue Iamitive-Kategorie zu etablieren. Was die Unterscheidung zwischen Realis und Irrealis betrifft, so habe ich festgestellt, dass die Kategorie Realis in Nafsan semantisch unterbewertet ist, wie sie in Irrealis-Kontexten auftreten kann, die mit der Bedeutung von Realis unvereinbar sein sollten. Ich schlage vor, dass “Realis” gelegentlich Realis-Bedeutungen durch pragmatischen Wettbewerb mit Irrealis erhaltet. Indem ich das “branching-times’’ Modell annehme, das den Ausdruck von Modalität und zeitlichem Bezug vereint (Prince, 2018), zeige ich, dass Nafsan und mehrere andere ozeanische Sprachen Beweise dafür liefern, dass Irrealis als Modalitätskategorie, die sich auf nicht-aktuelle Welten bezieht, eine semantisch sinnvolle Kategorie ist. / In this thesis I study the meaning of tense, mood, and aspect (TMA) expressions in Nafsan (South Efate), an Oceanic language of Vanuatu, from a typological perspective. I focus on the meanings of the perfect aspect and realis/irrealis mood in Nafsan and other Oceanic languages, as case studies for investigating the cross-linguistic features of these TMA categories, frequently disputed in the literature. In order to analyze their meanings in Nafsan, I studied the Nafsan grammar (Thieberger, 2006) and corpus by Thieberger (1995–2018), followed by storyboard and questionnaire elicitation in my fieldwork (Krajinovic, 2017b). I found that the Nafsan perfect has all the functions considered to be typical of the English-style perfect, except for the additional meaning of change of state. I place the analysis of the Nafsan perfect in the debate about the cross-linguistic validity of the newly proposed category of iamitives, defined by the meaning of change of state akin to `already' and lacking experiential and universal perfect functions (Olsson, 2013). Based on the data from Nafsan and other Oceanic languages, I show that, when language-internal processes are considered, the semantic definition of perfect proposed by Klein (1994) is sufficient to account for additional perfect functions, without the need to posit the new iamitive category. Regarding the realis/irrealis distinction, I have found that the “realis” category is semantically underspecified in Nafsan, as it can occur in irrealis contexts that should be incompatible with realis meanings. I propose that “realis” in Nafsan only occasionally receives realis meanings through pragmatic competition with the irrealis category. By adopting a branching-times model that unites the expression of modality and temporal reference (Prince, 2018), I also show that Nafsan and several other Oceanic languages provide evidence that irrealis as a mood category referring to non-actual worlds is a semantically meaningful category.
