This thesis consists of five empirical essays dealing with different issues related to financial markets. Chapter 2 studies a new multivariate technique, Orthogonal GARCH, of forecasting large covariance matrices based on GARCH models. Orthogonal GARCH is built on principal component analysis and makes the creation of positive definite covariance matrices of arbitrary size possible. An important d

This thesis contains three papers about three different estimates of resolvents in harmonic analysis. These papers are: Paper 1. ``A Wiener tauberian theorem for weighted convolution algebras of zonal functions on the automorphism group of the unit disc'' Paper 2. ``Uniform spectral radius and compact Gelfand transform'' Paper 3. ``Decomposable extension of the Cesáro operator on the weighted B

This monograph analyses marine gathering in the Polynesian Kingdom of Tonga from ecological, social and cognitive perspectives. The overarching issues explored are (1) the significance of marine gathering in the past and present, (2) how seaweeds and marine invertebrates have been perceived, classified, named and used, (3) how they have been implicated in social relations, and (4) how the integrat

The interaction between two colloids with grafted polyelectrolytes in aqueous solution is studied within the primitive model by Monte Carlo simulations. For neutral colloids with grafted polyelectrolytes and in absence of salt the interaction is strongly repulsive in absence of salt. The interaction depends on the extension of the polyelectrolytes from the surfaces and the interaction is derived a

Industrial robots play a key role in manufacturing systems. Robots are distinguished from other types of machinery mainly on the basis of their programmability and ability to be adaptable to different tasks. The use of computer control to achieve desired flexibility implies that software issues for embedded control systems are central for the applicability and utilization of the equipment. The str

The academic discourse on the need for a shared political public sphere at the level of the European Union has in recent years produced the conventional wisdom that such an emerging transnational community of communication is already observable in the mass media. However, the empirical indicators on which this notion is based tend to accommodate parallel national public spheres rather than a genui

Two new transamination systems are described. The first example is a dibenzo[a,d]- cycloheptene containing system, designed to accomplish a [1,3]-hydride transfer. Several catalysts have been examined for this purpose. tris-Pentafluorophenyl borane was found to be the most efficient catalyst. The stereochemistry of several closely related dibenzo[a,d]- cycloheptene have also been examined, display

Archaeology is about human beings – in the present and in the past. When we concern ourselves with archaeology we have to imagine prehistoric human beings thinking, feeling and acting. This imagining is the very precondition for the creation of meaning from the fragments and traces of human lives that we choose as our data. What kind of images of human beings do we create through the writing and r

This essay concerns the complementation of the English emotive verbs like, love, hate and prefer. In English, gerund-participial and infinitival complements often receive semi-synonymous semantic interpretations when complementing emotive verbs. All the while, both complement types supposedly convey separate semantic interpretations, resulting in that they commonly appear in contexts expressing ha
