A "compass rose" pattern sometimes appears when stock returns are plotted against themselves with a one-day lag, since stock prices move in discrete steps. In this paper, we perform a Monte Carlo study on simulated stock price series rounded in different ways to mirror the behavior of stocks on the Stockholm Stock Exchange. We find AR-GARCH parameter estimates to be affected by the discreteness im

Occasional verse and orations in separately printed leaflets at funerals, weddings and other celebrations was the dominant vehicle for literary production in Sweden in the 17th and 18th centuries. It honoured the recipients and promoted the authors. This aspect of print culture in the Swedish Age of Greatness is here summarized.

Listening Lund Sound environment centre at Lund university in Sweden is known to be the first interdisciplinary centre created with an aim to coordinate research on sound and sound environmental issues. Ranging från acoustics to medicin to juridics as well to humanities as musicology and ethnology sound environmental research adresses many interdepentent areas and topics. To be able to get a more

Popular Abstract in Swedish I plan to add a summary in Swedish at the WWW-page www.biokem.lu.se/education/theses/johannordthesis.htmRecombinant dUTPase from the bacterium Escherichia coli, the retrovirus equine infectious anemia virus (EIAV) and Homo sapiens have been made available for physico-chemical characterisation. The protocols developed have also proven to be suitable for production of enzymes modified by isotope labelling or other methods. The improved accessibility of enzyme material has enabled the subsequent invest

The issue and distribution of IT and IS students and professionals as dependent on Gender Bias is discussed. Background and examples are presented from the IT British Industry; the UK and the Swedish Educational sectors.

This paper presents a novel approach to the problem of designing autonomous agents that is based on the idea of anticipatory systems. An anticipatory system has a model of itself and of the relevant part of its environment and will use this model to predict the future. The predictions are then utilised to determine the agent’s behaviour, i.e. it lets future states affect its present states. We arg

Popular Abstract in Swedish Fyra högst migratoriska och utrotningshotade havssköldpaddsarter (soppsköldpadda, karettsköldpadda, havslädersköldpadda och oäkta karettsköldpadda) lägger ägg i Tortuguero nationalparken i Costa Rica. Havssköldpaddsforskning har pågått fortlöpande i Tortuguero sedan Dr. Archie Carr påbörjade studier under 1950-talet. Denna avhandling avser att klargöra Tortugueros havsTortuguero National Park in Costa Rica hosts nesting by four species of highly migratory and endangered sea turtles (green, hawksbill, leatherback and loggerhead turtles). Sea turtle research at Tortuguero has been continuous since Dr. Archie Carr began studies in the 1950?s. This dissertation aims to clarify the Tortuguero sea turtles? post-nesting migrations, nesting trends and survival threats.

Category housing is an example of forms of housing that belong to the organized work of providing residences for persons who for diverse reasons cannot obtain them on the ordinary housing market. In the organizing of the practical social work that is carried out for this purpose, categorization serves as an important tool for connecting the available housing alternatives with the individuals who s

Multimedia service delivery over the Internet is a success. The number of services available and the number of people accessing them is huge. In this paper, we investigate multimedia streaming services over the Internet. Our analysis is based on traffic measurement in live access fiber-to-the-home networks. We study parameters like traffic volume and flow characteristics for selected services. Esp

Let H1=(V,E1) be a collection of N pairwise vertex disjoint O(1)-spanners where the weight of an edge is equal to the Euclidean distance between its endpoints. Let H2=(V,E2) be the graph on V with M edges of non-negative weight. The union of the two graphs is denoted G=(V,E1 u E2). We present a data structure of size O(M^2 + nlogn) that answers (1+ε)-approximate shortest path queries in G in const
