A total of 103 secondary school children attending five schools managed by Lothian Regional Council were surveyed to establish nutrition knowledge, attitudes and beliefs about healthy eating and their patterns of food consumption at lunchtime on schooldays. The results indicate that nutrition knowledge was surprisingly good and the children surveyed were proficient at identifying foods that were high in fibre and low in sugar, salt and fat. When questioned about their liking for foods, however, many identified foods that were characteristically high in fat, sugar and salt, and low in fibre. Examination of the dietary diaries kept at lunchtime confirmed that consumption of these types of foods was typically high, with very low consumption of fruit and vegetables being reported and high intakes of carbonated drinks, confectionery and chocolate. This conflict between nutrition knowledge and food choice patterns is discussed in the light of the probable future effects on health and the implications for health educators. 相似文献

Previous research demonstrates that a firm's common stock price tends to fall when it issues new public securities. By contrast, commercial bank loans elicit significantly positive borrower returns. This article investigates whether the lender's identity influences the market's reaction to a loan announcement. Although we find no significant difference between the market's response to bank and nonbank loans, we do find that lenders with a higher credit rating are associated with larger abnormal borrower returns. This evidence complements earlier findings that an auditor's or investment banker's perceived “quality” signals valuable information about firm value to uninformed market investors. 相似文献

The present paper outlines rules for estimating realizable holding gains within a current cost framework. The foundation for the procedures lies with a theorem properly named for Edwards and Bell (1961). The theorem is stated and proved and then employed to derive the relevant quadrature rules. Estimates of the holding gains applicable to U.K. manufacturing industry are then made. The estimates are found to be highly sensitive to the quadrature rule used. 相似文献

Abstract. This paper empirically examines whether labor strikes affect the forecasting and information content of quarterly earnings numbers. We address two issues regarding financial analyst forecast (FAF) superiority: whether FAF superiority increases when a strike occurs and if so, whether the increase in FAF superiority is sustained immediately after the strike ends. We also examine two issues regarding information content: whether strikes affect the coefficient mapping unexpected earnings into stock prices and whether strikes affect the variance of stock price changes. We suggest that strikes affect both the forecasting and information content of quarterly earnings numbers. Résumé. Cet article examine de façon empirique si les grèves des travailleurs influencent la prévision et le contenu informatif des résultats trimestriels. Nous abordons deux questions relatives à la supériorité des prévisions d'analystes financiers (PAF): à savoir si la supériorité des PAF s'accroît lorsqu'une grève se produit et, dans l'affirmative, si l'accroissement de cette supériorité se maintient immédiatement après la fin de la grève. Nous étudions également deux questions relatives au contenu informatif: à savoir si les grèves influencent le coefficient incorporant l'impact des bénéfices imprévus sur le cours des actions et si les grèves affectent la variance des fluctuations du cours des actions. Les grèves affecteraient donc à la fois la prévision et le contenu informatif des résultats trimestriels. 相似文献

This paper provides some new insights about approximate factor structures, as defined by Chamberlain and Rothschild [2], and their implications for empirical tests. First, we show that any economy that satisfies an approximate factor structure can be transformed, in a manner that does not alter the characteristics of investor portfolios, into an economy that satisfies an exact factor structure, as defined by Ross [9]. Second, we show that principal components analysis represents just one of many methods of forming groups of well-diversified portfolios with no idiosyncratic risk in large samples. Correct factor loadings will be obtained by regressing security returns on any group of these portfolios. Our interpretations of the Chamberlain and Rothschild results also provide additional insights into the testability of the Arbitrage Pricing Theory. We show that securities cannot be repackaged to hide factors in the manner suggested by Shanken [10] without the variance of some of the repackaged securities approaching infinity in large economies. 相似文献

A partial equilibrium model is used to analyze effects of Chinese currency revaluation on world fiber markets. Unique characteristics of this model include incorporation of a regional supply response of cotton, substitutability between cotton and manmade fibers, and linkage between raw fiber and textile sectors. Simulation results show renminbi revaluation is likely to increase China's fiber imports and lower domestic cotton prices. Internationally, the world cotton price, polyester price, and cotton trade are expected to increase. A scenario modeling currency devaluation in China is run to test the stability of the model and ascertain its accordance with economic theory . ( JEL F17, F42, F47, O2) 相似文献

Information on the allocation and pricing of over‐the‐counter (OTC) markets is scarce. Furfine (1999) pioneered an algorithm that provides transaction‐level data on the OTC interbank lending market. The veracity of the data identified, however, is not well established. Using permutation methods, I estimate an upper bound on the daily false positive rate of this algorithm to be between 10% and 20%. I propose refinements that reduce the bound to 10% or lower with negligible power loss. The results suggest that the inferred prices and quantities of overnight loans provide viable estimates of interbank lending market activity for Canadian data. 相似文献
