In-sample forecasting: structured models and reserving
In most developed countries, the insurance sector accounts for around eight percent of the GDP. In Europe alone the insurers liabilities are estimated at around e900 billion. Every insurance company regularly estimates its liabilities and reports them, in conjunction with statements about capital …

The persistence of business performance in sample soybean farms from Mato Grosso and Illinois
Direct farm land investment and ownership by non-traditional institutional, private equity, and sovereign wealth funds has increased in recent years as investors find attractive characteristics in this asset class such as favorable risk adjusted returns, an inflation hedge, and a negative …

Comparing Extraction Methods in Sample Preparation for the Quantification of Cannabinoids in Industrial Hemp
Industrial hemp is legally defined in the United States by the Agriculture Improvement Act of 2018 (2018 Farm Bill) as Cannabis containing <0.3% total tetrahydrocannabinol (THC). The 2018 Farm Bill does not, however, specify standard methods for sample preparation or quantification of cannabinoids …

From Sample to Answer: Innovations in sample processing and CRISPR-based diagnostics for enhanced clinical translation and field deployment
The recent (re)emergence and rapid spread of infectious disease agents underscore the urgent need for effective disease prevention and control strategies. Accurate and timely diagnostics serve as the base for effective disease management, enabling the rapid identification of disease outbreaks, …

Identify Causes of Unacceptable Turnaround Time in Sample Recalls and Develop Corrective Actions to Improve Patient Service in the Clinical Laboratory
… attributed to the preanalytical phase of testing, determine the most frequent, actionable cause, and work collaboratively to create a standard workflow to improve the quality of testing while concurrently saving wasted money and resources. For tests that were inevitably canceled, we focused on …

Detecting macroeconomic impacts on agricultural prices and export sales: a time series forecasting approach
The effect of movements in the real exchange rate on agricultural prices and agricultural export sales is assessed based on the principle of Granger causality. An out-of-sample forecasting procedure is used to conduct tests for Granger causality from the exchange rate to agricultural prices and …

Estimating and Forecasting the Term Structure of Interest Rates:US and Colombia Analysis
In this paper we use the most representative models that exist in the literature on term structure of interest rates. In particular, we explore affine one factor models and polynomial-type approximations such as Nelson and Siegel. Our empirical application considers monthly data of USA and Colombia …

The relationship between children's understanding of musical ability and their motivation, perceived ability and achievement in general music class
Children's understanding of ability and its relationship to effort was examined, and characteristics believed to be related to the level of their understanding were described. Two stratified random samples were drawn from among fourth, fifth and sixth grade students at three elementary schools in a …

Forecasting the Yield Curve of Government Bonds: A Comparative Study
… have applied the Kalman filter to the modeling and forecasting the term structure of interest rates. Despite its impressive performance in in-sample fitting yield curves, little research has focused on the out-of-sample forecast of yield curves using the Kalman filter. The goal of this …

The role of fairness, transparency, and feedback in driving motivation and performance among employees in incentive-based roles
… Theory and Expectancy Theory, this study examined how perceived pay fairness, reward transparency, and feedback quality explained self-determined work motivation among incentive-based employees, and whether relationships varied by career stage. Data were collected from two independent samples …

Evaluating yield models for crop insurance rating
Crop insurance performance and loss rates depend directly on underlying crop yield distributions. However, there still exists much debate about how to represent the underlying crop yield distributions. Using farm-level corn and soybean yields from 1972-2008, this study examines in-sample …

Google Econometrics: An Application to the Czech Republic
… za pomoci srovnání jak přesnosti 'out-of-sample' předpovědí, tak 'in-sample' kvality modelů oproti kontrolním proměnným ve třech oblastech: s využitím autoregresního modelu pro nezaměstnanost, vekto- rové autoregrese a logit modelů pro HDP a spotřebu domácností, a 'Granger causality test' …

Resonance raman scattering studies of GaAs-A1As superlattices
"We have made resonance Raman scattering studies of folded LA phonons and quantized LO phonons in several GaAs-AlAs superlattices. The motivation for this work was to study the electronic structure and the electron-phonon interaction in these structures. The samples were not intentionally doped. …

The determination of HETP and column efficiency for an annular preparative-scale gas-liquid chromatographic column
The purpose of this investigation was to design, build, and test a preparative-scale column which contained a blocked-off center tube, thus forming an annular space for the packing. The chromatographic system for this study consisted of 1-methylnaphthalene injections with helium carrier gas and a …

Bond yield modelling and its application in the European Union
Forecasting crises has always been an interesting and important topic for econometricians or statisticians. Literature suggests that government bond yields can be a valid leading indicator for this purpose. This thesis uses government bond yields and applies various models to forecast the crisis …

Comparing GARCH models for gold price data, using a statistical loss function approach and an option pricing approach
Derivative instruments that rely on the price of gold are traded in large volumes. A significant number of these instruments are influenced by the volatility of gold price movements. Hence, it is important to understand the volatility of this commodity when developing successful trading and hedging …

Optimization of solvent suppression sequences for NMR analysis of aqueous solutions
"When the use of deuterated solvents is precluded in the NMR analysis of biomolecules in their natural environment, pre-saturation solvent suppression pulse sequences are frequently employed to avoid interference from the overbearing solvent signal. However, these sequences generally require …
