Typological features can be expected to exhibit the same diachronic development multiple times during the history of a language family, exhibiting what is known variously as recurrence, homoplasy, or drift. This paper seeks to quantify the areal signal shown by recurrent mor- phosyntactic changes across the Indo-European language family. We use 108 morphosyntactic feature variants taken from the DThis article investigates the evolutionary and spatial dynamics of typological characters in 117 Indo-European languages. We partition types of change (i.e., gain or loss) for each variant according to whether they bring about a simplification in morphosyntactic patterns that must be learned, whether they are neutral (i.e., neither simplifying nor introducing complexity) or whether they introduce

Flera forskningsprojekt vid vår avdelning är inriktade på att bättre förstå mekanismer som ligger bakom utvecklingen av svåra infektionssjukdomar, fr.a. orsakade av bakterier men också av virus och svampar. Utgångspunkten för arbetet har ofta varit upptäckten av bakteriella ytproteiner och enzymer som på olika sätt interagerar med människans försvarssystem (medfödd och förvärvad immunitet och blodSeveral research projects at our Division are focused on molecular and cellular mechanisms that contribute to the development of severe infections caused preferentially by bacteria, but also by viruses and fungi. The starting point for this work has often been the discovery of bacterial surface proteins and enzymes that interact with human defenses (innate and acquired immunity and blood coagulati

Galatians is a polemical letter which contains a substantial amount of argumentative passages. Paul evidently wanted to persuade by using the best arguments possible to convince his addressees. Using a state-of-the-art method from the discipline of argumentation analysis, Paul's argumentation can be analysed with a precision that standard exegetical methods cannot provide.

The current state of the water and sanitation sector has put water-related innovations high on the global policy agenda. However, the systemic complexity that typically surrounds such contexts call for actionable knowledge of how to enable and orchestrate innovative solutions by connecting different players via organized networks. In this study we explore and analyse the Water Innovation Accelerat

This thesis takes an interest in newer forms of contract-based dispute resolution used in commercial disputes. Public civil trial and arbitration has for a long time been the procedure of choice for disputing commercial parties. Arbitration is still by far the most established and used procedure when it comes to private dispute resolution. However, for some decades, newer forms of private procedur

Under drygt 15 år har Pufendorfinstitutet välkomnat hundratals interdisciplinära forskargrupper, som alla förenas genom att de vill utforska vetenskapliga problem, just genom att nyfiket och engagerat ta sig an det från olika ämnesdiscipliner. All forskning som bedrivits här har varit i ett tidigt eller mycket tidigt skede. De frön som forskare sått här tillsammans genom åren har ofta mognat och l
