The Effect of Labour Taxation on the Employment Level

Over the past decade an increase in labour taxation reforms have been observed across several countries. The main target of these reforms has generally been to encourage labour supply among different groups. In the case of Sweden, an earned income tax credit was introduced in 2007 and reinforced in 2008, 2009, 2010 and 2011 as a measure to deal with the high unemployment level. The relationship be

Impersonal null-subjects in Icelandic and elsewhere

We study the properties of impersonal null-subjects, in particular in Icelandic, exploring the idea that such elements are constructed in syntax (rather than being lexical pronouns deleted in PF). In addition, we discuss the cross-linguistic distribution of impersonal null-subjects.

Anatomy and taxonomy of cetrarioid lichens

The anatomy of the cetrarioid lichens (Parmeliaceae) has been studied, and the taxonomy revised. Special attention has been paid to reproductive structures, in particular the asci and pycnoconidia. Two types of asci are recognized. The Cetraria type is narrowly clavate, bears an amyloid ring structure in the tholus, and has a small axial body. The Lecanora type, specifically the Melanelia form, is

Stabilization of Vehicle Formations-A Case Study

This work treats a specific multi-vehicle control case, namely six vehicles on the Multi-Vehicle Wireless Testbed (MTWT), wich is an arena at Caltech, California, built for doing experiments on small vehicles. A model is set up and a controller is found through simulations that stabilizes the system. Stability is proven through a Nyquist-like criterion.

Induction Machine Speed Estimation - Observations on Observers

This work focuses on observers estimating flux linkage and speed for induction machines, mainly in the low speed region. With speed estimation, sensorless control is possible, meaning that the speed of induction machines without mechanical speed sensors can be controlled. The observer based sensorless drive system has superior dynamic performance compared to a system with an open loop frequency in

Causal Facts

The thesis addresses the nature of causation. It is argued that causation exists and is as local as its causes and effects. As a consequence, the position advocated is contrary to the as yet prevailing view that no 'causal tie' between cause and effect exists. Moreover, it is suggested that this tie can be perceived. The essay attempts to elucidate the nature of causes, effects, and causal mechani

Histamine and chromogranin A-derived peptides in rat stomach ECL cells

The ECL cells constitute the predominant endocrine cell population of the stomach. They secrete histamine which is a major stimulator of acid secretion. Chormogranin A (CgA)-derived peptides, such as pancreastatin, are co-secreted with histamine. In this thesis it was demonstrated that pancreastatin may serve as a reliable marker for ECL cell secretory activity in the rat. The function of pancreas
