This thesis consists of four essays discussing network structures and institutions in financial markets. The first essay explores the determinants of the egocentric lending networks of stock listed companies in China. Egocentric lending networks are constructed using the public loan announcements of firms listed on China’s two stock exchanges combined with cross-ownership shares connecting the len

We present a systematic study of the angular distributions of high-order harmonics generated with a femtosecond Cr:LiSrAlF6 laser. We investigate the influence of different parameters, namely laser intensity, nonlinear order, nature of the gas and position of the laser focus relative to the generating medium. We show that when the laser is focused before the atomic medium, harmonics with regular s

PURPOSE: To investigate whether blue-collar employment in the Swedish rubber industry from 1973 onwards had a negative impact on reproductive health. METHODS: Pairs of mother and child, and triads of father-mother-child were obtained through linkage of a cohort of 18,518 rubber factory employees with the Swedish Population Registry. Birth outcomes were obtained from the Medical Birth Register for

Skolans undervisning i naturvetenskap kan lägga grunden för intresse och vidare studier inom de naturvetenskapliga och tekniksa ämnena, och strävar också efter att get en god allmänbildning som medborgarkunskap. I oktober 2011 anordnade NRCF ett nationell Fysikbromöte i Göteborg för att bygga broar mellan fysiker och gymnasielärare kring olika frågor.

Inspired by the recent Hubble Space Telescope first observations of arsenic in an astrophysical object we have determined the natural radiative lifetime of the upper states of two of the three resonance lines of As I. Short pulse laser excitation at 193.7 and 197.2 nm was achieved using different non-linear optical mixing schemes. Using time-resolved spectroscopy we obtain tau(4p(2)5s P-4(3/2))=4.

In May 2012 Alex Sharpe, Professor of Law at Keele University, UK, visited Lund University where she participated in a series of seminars and workshops organised around a central motif in her work: the legal outsider. As part of her visit she presented a version of a paper recently published in the Modern Law Review titled “Transgender Marriage and the Legal Obligation to Disclose Gender History.”

Uncracked reinforced concrete slabs were field exposed mounted on a floating pontoon and partly submerged for 5 years at the Swedish west coast. The total chloride ingress was analysed at various exposure times at 3 elevations representing a submerged, a splash, and an atmospheric exposure zone. The concrete mixtures varied in w/c ratio, type of cement, and amount and type of pozzolan used in the

Time-gated imaging is a new technique for scatter suppression in radiological imaging, based on the use of ultrashort x-ray pulses in combination with a fast gatable detector. We demonstrate scatter suppression in both planar and computed tomography (CT) radiography in an experimental model using x rays from a laser-produced plasma. The scatter-suppression efficiency of time-gated imaging is found

Miljardmarknad med dödliga konsekvenser. Falska mediciner är ett nästan okänt hälsohot för svensk allmänhet, trots att de dyker upp bland läkemedel som köps på internet. Andelen svenskar som handlar mediciner på nätet ökar. Nu krävs tydlig och återkommande information om farorna med förfalskningar, skriver Susanne Lundin.

Abstract in Danish Blandt geografer huskes Gudmund Hatt nok især som professoren, der efter besættelsen blev afskediget for „uværdig national optræden“. Det skyldtes ikke mindst de „tyskvenlige“ geopolitiske analyser, han som en del af samarbejdspolitikken udfoldede i radioen og i det Berlingske Blade. Nogle vil måske også huske Hatt for de lidet flatterende racistiske passager i Jorden og Mennesk

Background/Objectives:Few studies have used biomarkers of whole-grain intake to study its relation to glucose metabolism. We aimed to investigate the association between plasma alkylresorcinols (AR), a biomarker of whole-grain rye and wheat intake, and glucose metabolism in individuals with metabolic syndrome (MetS).Subjects/Methods:Participants were 30-65 years of age, with body mass index 27-40

Maternal use of some drugs, notably paracetamol and drugs for gastroesophageal reflux, has been associated with an increased risk of childhood asthma in the child. We wanted to analyze these associations with consideration to the confounding of maternal asthma.
