An iterative procedure to obtain inverse response functions for thick-target correction of measured charged-particle spectra
A new method for correcting charged-particle spectra for thick target effects
is described. Starting with a trial function, inverse response functions are
found by an iterative procedure. The variances corresponding to the measured
spectrum are treated similiarly and in parallel. Oscillations of the solution
are avoided by rebinning the data to finer bins during a correction iteration
and back to the original or wider binning after each iteration. This
thick-target correction method has been used for data obtained with the MEDLEY
facility at the The Svedberg Laboratory, Uppsala, Sweden, and is here presented
in detail and demonstrated for two test cases.Comment: 14 pages, 8 figures, submitted to NIM
Tutorial on Neutron Physics in Dosimetry
Almost since the time of the discovery of the neutron more than 70 years ago,
efforts have been made to understand the effects of neutron radiation on tissue
and, eventually, to use neutrons for cancer treatment. In contrast to charged
particle or photon radiations which directly lead to release of electrons,
neutrons interact with the nucleus and induce emission of several different
types of charged particles such as protons, alpha particles or heavier ions.
Therefore, a fundamental understanding of the neutron-nucleus interaction is
necessary for dose calculations and treatment planning with the needed
accuracy. We will discuss the concepts of dose and kerma, neutron-nucleus
interactions and have a brief look at nuclear data needs and experimental
facilities and set-ups where such data are measured.Comment: Invited talk at the 11th Neutron and Ion Dosimetry Symposium

The cointegrating relationship in Asian markets with applications to stock prices, exchange rates and interest rates
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.The aim of this research is to investigate the long-run co-integrating relationships in the Asian markets. Our research focuses on 4 areas; pair trading, out-of-sample forecasting, testing the unbiased forward exchange rate hypothesis and testing the expectation hypothesis of the term structure of interest rates. The introduction is provided in chapter one. In chapter two, we develop a pairs trading strategy using individual stocks listed in the Stock Exchange of Thailand. Engle and Granger approach is used to identify the potential pairs that are cointegrated. The results show that pairs trading strategy is profitable in this market. Chapter three examines the forecasting performance of the error correction model on daily share price series from the Stock Exchange of Thailand. The disequilibrium term is classified into “correct” and “mix” sign based on Alexander (2008)’s criterion; the results indicate that the error correction component can help to improve the predictability in the long run. Chapter four tests the unbiased forward rate hypothesis of 11 Asian exchange rates using linear conventional regression, ECM and logistic smooth transition regression with the forward premium as the transition variable. Out-of-sample forecasting results also suggest that inferior forecasting performance could be obtained as a result of using linear models. In chapter five, we investigate the expectation hypothesis of the term structure of interest rate for four Asian countries. We employ linear models and nonlinear approaches that allow to capture asymmetric and symmetric adjustments. The result also indicates that the term structure can be better modeled by means of LSTR models. The forecasting exercise also confirms these findings

Is International or Asian Criteria-based Body Mass Index Associated with Maternal Anaemia, Low Birthweight, and Preterm Births among Thai Population?—An Observational Study
An observational study was conducted in the four southernmost provinces of Thailand aiming at determining the effect of international or Asian criteria-based body mass index (BMI) in predicting maternal anaemia, low birthweight (LBW), and preterm births among pregnant Thai women and the change in haemoglobin (Hb) level during pregnancy. Maternal anaemia was defined as a haemoglobin (Hb) level of <11 g/dL. Anaemia was detected in 27.4% and 26.9% of 1,192 pregnant women at their first prenatal visit and the third trimester respectively. The proportions of overweight and obese women according to the Asian criteria-based pre-pregnancy BMI were higher than the international criteria-based BMI (22.4% and 10.1% vs 15.5% and 3.4% respectively). No significant difference between pre-pregnancy BMI and pregnancy BMI at the first prenatal visit was demonstrated (mean±standard deviation=21.8±4.0 vs 22.8±4.1). Underweight women had a significantly higher prevalence of maternal anaemia, LBW, and preterm birth compared to women with normal weight. Overweight and obese women at pre-pregnancy by the Asian criteria-based BMI had a lower prevalence of anaemia. The Hb levels did not change significantly over time. In addition to BMI, maternal age, parity, and late prenatal visit were independently associated with maternal anaemia, low birthweight, and preterm birth. Underweight pregnant women classified by international or Asian criteria-based BMI increased the risk of maternal anaemia, low birthweight, and preterm birth
Theravada Buddhismus aus feministischer Perspektive
1. Die Lehre des Buddhismus ist die Lehre von Ursache und Wirkung. Buddha sagt:"Wer das bedingte Entstehen versteht, versteht Dharma, wer den Dharma versteht, versteht das bedingte Entstehen". Dharma ist die Lehre des Buddha. Dharma bedeutet "Wahrheit", "Gesetzmäßigkeit", "Naturgesetzt". Die gesamte Lehre von Buddha handelt von Menschen, von uns und von der Natur. Buddha hat ein andermal gesagt: "Die Lehre über das Entstehen in Abhängigkeit ist sehr tiefgründig und subtil". Nur mit dem Intellekt können wir es nicht "verstehen." Wörter sind leider nur ein lineares intellektuelles Mittel, was begrenzt ist...
The Roles of Social Capital and Knowledge Sharing Behavior in Myanmar’s Private Banks
This research discloses the roles of social capital, knowledge sharing intentions, and knowledge sharing behavior in the context of Myanmar’s private banking sector. Two hundred and seventy five questionnaires were collected from mid-management level employees in the private banking sector using a survey technique. To estimate the proposed research model, structural equation modelling (SEM) was applied. The results, firstly highlight that social capital significantly influences knowledge sharing intentions, and secondly, that knowledge sharing intentions partially mediate the path from social capital and knowledge sharing behavior. This confirms the importance of socially-related factors regarding the motivation and behavior aspects of knowledge sharing between individuals. The findings enable organizations in Myanmar to appreciate the sharing behavior between employees, regarding knowledge. With respect to the practical implications, this study could offer useful insights into how organizations can design and implement effective practices to enhance knowledge sharing behavior in their organization, via effective stimulation of motivation. In this way, organizations can attain sustainable development of human capital and gain a competitive advantage
