Essays on Network Effects and Money

Popular Abstract in Swedish Denna avhandling består av fyra separata artiklar. Den gemensamma nämnaren för alla artiklarna är att de behandlar pengar och nätverkseffekter. En vara med nätverkseffekter är en vara där nyttan av varan är beroende av hur många andra individer som använder sig av varan. Ett typexempel i litteraturen är faxmaskiner: ju fler som har en fax, desto större nytta har man av This thesis contains four separate papers in the field of monetary economics. The common basis for all the papers is that they deal with money and network effects in one way or another. Although the common basis is the same in all the articles, different approaches are used: theory, econometrics and history of economic thought. This first essay focuses on the network effect in the use of money an

Quality of life associated with varying degrees of chronic lower limb ischaemia: comparison with a healthy sample

OBJECTIVES: To assess quality of life in patients with varying degrees of ischaemia in comparison with controls, and to determine whether the degree of lower limb ischaemia and sense of coherence were associated with quality of life. MATERIALS AND METHODS: 168 patients, including 93 claudicants and 75 patients with critical ischaemia and 102 controls were studied. Quality of life was assessed usin

Protease activities in the chloroplast capable of cleaving an LHCII N-terminal peptide

Two protease activities of pea chloroplasts, one located in the stroma and the other associated to the thylakoid membrane, are described. Both proteases catalyse the endo-proteolytic cleavage of a peptide corresponding to the N-terminal loop and the first turn in helix-B of light-harvesting complex II (Lhcb1 from pea). The stromal protease cleaves preferentially on the carboxy-side of glutamic aci

Minimizing tissue-material interaction in microsensor for subcutaneous glucose monitoring

A new implantable electrocatalytic glucose sensor for subcutaneous glucose monitoring has been fabricated by immobilizing glucose oxidase on a chemically modified carbon fiber. The sensor was inserted subcutaneously on a male spraguely rat without any incision after dipping the microsensor in the rat's serum for 3 days. The so called "stained" microsensor, operated in the amperometric mode with an

Five Studies in Ethics and Gene Technology

I denna artikel kommenterar jag fem arbeten som alla behandlar modern genteknik ur etisk synpunkt, med hjälp av såväl teologisk som filosofisk etik. Böckerna tas som intäkt för att kortfattat diskutera några etiska problem i anslutning till genteknikens möjligheter, bland annat: Bör vi med genteknik skapa framtida människor med evigt liv? Hur kan vi fatta moraliskt välgrundade beslut som berör fra

Coronary heart disease mortality after 5 years of adjuvant tamoxifen therapy: Results from a randomized trial

From January 1, 1983, through December 31, 1992, a total of 4610 patients entered a randomized trial that compared mortality among patients receiving 2 years of adjuvant tamoxifen therapy with that in patients receiving 5 years of adjuvant tamoxifen therapy, 4175 of whom were recurrence free after 2 years of tamoxifen therapy. Among the 2046 patients randomly assigned to the 5-year group all-cause

The philosophy of Joseph Margolis

In this article I focus on some of Joseph Margolis's contributions to medical ethics. I first discuss some of Margolis's normative and metaphysical views on death and abortion, particularly in his early work Negativities, as well as some of his metaphysical assumptions. Then these views and assumptions are related to his theory of persons and, by implication, his theory of culture, set forth in a

Structural basis for SH2D1A mutations in X-linked lymphoproliferative disease

X-linked lymphoproliferative disease (XLP) is a rare and severe immune deficiency, characterized by abnormal immune responses to the Epstein-Barr virus. Recently, the gene responsible for XLP, SH2D1A, has been identified and shown to code for a small cytoplasmic protein with an SH2 domain that interacts with SLAM and 2B4, two receptorial molecules involved in signal transduction in T and NK cells,

The role of glycosaminoglycan binding of staphylococci in attachment to eukaryotic host cells

Attachment of microorganisms to host cells is believed to be a critical early step in microbial pathogenesis. The aim of the study was to determine the role of the known glycosaminoglycan (GAG) binding activity of Staphylococcus aureus and coagulase-negative staphylococci (CoNS) in their attachment to six different eukaryotic cell lines. Three staphylococcal species expressing GAG binding capacity

Neighborhood social participation, use of anxiolytic-hypnotic drugs, and women's propensity for disability pension: a multilevel analysis

Aims: The increasing number of people on disability pension in Sweden is of concern for Swedish policy-makers, and there is a need for a better understanding of the mechanisms behind disability pension. We investigated ( i) whether women living in the same neighborhood have a similar propensity for disability pension that relates to neighborhood social participation, and ( ii) whether there is an

Introduction to multi-jet final states and energy flows

We summarize the activities of Working Group 2 of the HERA/LHC Workshop dealing with multi-jet final states and energy flows. Among the more specific topics considered were underlying event and minimum bias, rapidity gaps and survival probabilities, multi-jet topologies and multi-scale QCD, and parton shower–matrix element matching.

Object relation quality, alexithymia, and defense mechanisms of drug abusers with antisocial personality disorder

The purpose was to investigate, in a sample of drug abusers, whether subscales in the KAPP (Karolinska Psychodynamic Profile, Weinryb, 1992) interview and defense mechanisms explored by the DMTm (Defense Mechanism Technique modified) could differentiate between DSM-III-R clusters and personality disorders (PDs). Forty-seven (47) subjects out of the 84 injecting drug abusers (56%) recruited from a
