Few Welsh Black Cattle breeders record their animals as part of formal selection schemes. However there are sale and pedigree data available on Welsh Black Cattle as recorded by the breed society. The aim of the current project was to examine the use of market price as a basis for selection. This is justified on the basis that detailed production records are not available and that price could be considered as an indicator that summarises physical characteristics.

Mental Integration

Investors have a proven general reluctance to realize losses. The theory of “mental accounting” suggests that losses are easier to accept when mentally integrated with either preceding losses or with compensatory gains. Mental integration is made easier when a failed asset is exchanged against a new, apparently profitable, acquisition. The alternative is to sell the existing asset on the open market before re-investing the proceeds as desired. This is emotionally less appealing than “rolling over” a losing investment into a new venture by way of an asset trade. The psychological benefits of exchanging rather than selling a failed asset come at a cost. It is typical of trade-in arrangements, e.g., where one trades an old car against a new one, that the effective sale price of the existing asset is less than current market value. Acceptance of this low price adds to the investor's total monetary loss on the existing asset but is essential to an overall package deal apart from which that asset would often remain belatedly unsold.

Company Value

This study aims to get empirical evidence about the infuence of IT spending on corporate value by testing the efect of IT spending on corporate value by using Tobin’s Q. Te higher the stock price, the higher the company value as well as investors’ assessment. The market price of the company’s stocks refects investors’ assessment of the overall equity held. Of the stock price refects investor can provide an assessment of a company. Tobin’s Q is the ratio of the market value of the company’s assets as measured by the market value of the outstanding stocks and debt (enterprise value) to the replacement cost of the assets of the company. The sampling method is based on purposive sampling method with the purpose to obtain a sample that meets the criteria. Tis study used a sample taken from a telecommunications company listed on the Stock Exchange throughout Southeast Asia during the period of 2009-2011. The hypothesis in this study was tested using simple regression. Based on data analysis, the result that the variable IT spending does not afect the company value.Keywords: accounting information system, Tobin’s Q, IT spending, capital expenditure, company performance

Synthetic Hexaploid

Abstract Cultivated bread wheat (Triticum aestivum L.) is an allohexaploid species resulting from the natural hybridization and chromosome doubling of allotetraploid durum wheat (T. turgidum) and a diploid goatgrass Aegilops tauschii Coss (Ae. tauschii). Synthetic hexaploid wheat (SHW) was developed through the interspecific hybridization of Ae. tauschii and T. turgidum, and then crossed to T. aestivum to produce synthetic hexaploid wheat derivatives (SHWDs). Owing to this founding variability, one may infer that the genetic variances of native wild populations vs improved wheat may vary due to their differential origin and evolutionary history. In this study, we partitioned the additive variance of SHW and SHWD with respect to their breed origin by fitting a hierarchical Bayesian model with heterogeneous covariance structure for breeding values to estimate variance components for each breed category, and segregation variance. Two data sets were used to test the proposed hierarchical Bayesian model, one from a multi-year multi-location field trial of SHWD and the other comprising the two species of SHW. For the SHWD, the Bayesian estimates of additive variances of grain yield from each breed category were similar for T. turgidum and Ae. tauschii, but smaller for T. aestivum. Segregation variances between Ae. tauschii—T. aestivum and T. turgidum—T. aestivum populations explained a sizable proportion of the phenotypic variance. Bayesian additive variance components and the Best Linear Unbiased Predictors (BLUPs) estimated by two well-known software programs were similar for multi-breed origin and for the sum of the breeding values by origin for both data sets. Our results support the suitability of models with heterogeneous additive genetic variances to predict breeding values in wheat crosses with variable ploidy levels.

The Relationship

Abstract Background In honey bees, observations are usually made on colonies. The phenotype of a colony is affected by the average breeding value for the worker effect of the thousands of workers in the colony (the worker group) and by the breeding value for the queen effect of the queen of the colony. Because the worker group consists of multiple individuals, interpretation of the variance components and heritabilities of phenotypes observed on the colony and of the accuracy of selection is not straightforward. The additive genetic variance among worker groups depends on the additive genetic relationship between the drone-producing queens (DPQ) that produce the drones that mate with the queen. Results Here, we clarify how the relatedness between DPQ affects phenotypic variance, heritability and accuracy of the estimated breeding values of replacement queens. Second, we use simulation to investigate the effect of assumptions about the relatedness between DPQ in the base population on estimates of genetic parameters. Relatedness between DPQ in the base generation may differ considerably between populations because of their history. Conclusions Our results show that estimates of (co)variance components and derived genetic parameters were seriously biased (25% too high or too low) when assumptions on the relationship between DPQ in the statistical analysis did not agree with reality.

Objetivou-se neste trabalho avaliar o preço mínimo de venda de madeira de eucalipto com reflorestamentos destinados aos segmentos de carvão e serraria. O preço mínimo foi determinado através dos dados de custos e receitas dos empreendimentos. Os custos dos projetos foram descontados para o ano zero, somados e igualados a receita, também descontada para o ano zero.  A receita foi expressa pelo produto do Incremento Médio Anual, idade de corte, e preço mínimo de venda da madeira. Foram obtidos os seguintes preços mínimos de venda para madeira: carvão (R$ 38,44 para madeira em pé e R$ 55,39 para madeira empilhada); serraria (R$ 29,76 para madeira em pé e R$57,71 para madeira empilhada). Os valores encontrados foram inferiores ao preço de mercado, evidenciando que o custo de produção da madeira foi totalmente assegurado pelo seu preço de venda, proporcionando ainda um adicional de receita para cada metro cúbico comercializado. A análise de sensibilidade mostrou grande influência da taxa de juros no preço mínimo de venda da madeira, diferentemente do que foi observado para o custo anual de arrendamento da terra. Os resultados da pesquisa mostram importância ao nortear produtores florestais em relação aos preços de comercialização de produtos.Palavras-chave: planejamento econômico, projetos florestais, custo de madeira. MINIMUM SALE PRICE OF EUCALYPT TIMBER CONSIDERING REFORESTATION TO VEGETAL COAL PRODUCTION AND SAWMILL ABSTRACT:The objective of this study was to evaluate the minimum selling price of eucalyptus wood with reforestation for the coal and sawmill segments. The minimum price was determined by the cost and revenue data of the projects. Project costs were discounted for year zero, plus and equal to revenue, also discounted for year zero. Revenue was expressed as the product of the Annual Average Increase, age of cut, and minimum selling price of the wood. The following minimum selling prices were obtained for wood: coal (R $ 38.44 for standing timber and R $ 55.39 for stacked timber); (R $ 29.76 for standing timber and R $ 57.71 for timber stacked). The values found were lower than the market price, evidencing that the cost of production of the wood was fully assured by its selling price, also providing an additional revenue for each cubic meter marketed. The sensitivity analysis showed a large influence of the interest rate on the minimum selling price of the wood, unlike what was observed for the annual cost of renting the land. The results of the survey show importance when guiding forest producers in relation to the prices of products commercialization.Keywords: economic planning, forestry projects, timber cost.

Friesian Cows

Cattle breeders, farmers and vets believe that the decline in fertility seen in recent years can be partially attributed to changes in rump angle with selection being for more angular cows. This suggests that animals with pin bones that sit above the hip bones (high rump angle) will have poorer fertility. Few studies have shown a significant relationship between fertility and rump traits. This study investigates the popular belief that high rump angle equates to poor fertility by examining the genetic and phenotypic correlation between rump angle and fertility traits. The relationship between rump angle and fertility was also examined to see if there was an intermediate optimum or threshold of rump angle for good/bad fertility. The correlation of other type traits (udder and composite traits) with fertility was also examined to see if they had potential to add information to the estimation of fertility breeding values.
