虎鲨对温度、pH值的耐受性研究

本文报道了在LRH-250E型培养箱中对平均尾重0.2g和1.2g的虎鲨进行温度耐受性试验,并对均重1.2g的虎鲨做了pH耐受性研究。结果表明:尾重O.2g的虎鲨在驯化温度为20℃时,水温突变引起的致死高温为41℃,致死低温为14℃;尾重1.2g虎鲨在驯化温度为24℃时,水温突变引起的致死高温是42℃,致死低温为14.5℃。尾重1.2g虎鲨能够耐受的pH值其上限是11.51,下限是2.52。

斯·茨威格的教育思想

茨威格在其回忆录和一些小说中，对奥地利当时的教育制度、教学计划、学校、教育者、学生等都是有颇多微词的。今天再来审视茨威格对他的中小学生活的回忆，可以看出他对旧教育制度的愤懑，也不难发现其中蕴含着具有远见卓识的教育理念，这在２１世纪我们大兴创新教育之际仍有借鉴作用。     

Simple detection of outlying short time series

Sets of relatively short time series arise in many situations. One aspect of their analysis may be the detection of outlying series. We examine the performance of standard normal outlier tests applied to the means, or to simple functions of the means, of AR(1) series, not necessarily of equal lengths. Although unequal lengths of series implies that the means have unequal variances, that are only known approximately, it is shown that nominal significance levels hold good under most circumstances. Thus a standard outlier test can usefully be applied, avoiding the complication of estimating the time series' parameters. The test's power is affected by unequal lengths, being higher when the slippage occurs in one of the longer series     

Inference for the measurement of poverty in the presence of a stochastic weighting variable

Empirical applications of poverty measurement often have to deal with a stochastic weighting variable such as household size. Within the framework of a bivariate distribution function defined over income and weight, I derive the limiting distributions of the decomposable poverty measures and of the ordinates of stochastic dominance curves. The poverty line is allowed to depend on the income distribution. It is shown how the results can be used to test hypotheses concerning changes in poverty. The inference procedures are briefly illustrated using Belgian data. An erratum to this article can be found at     

Randomized response techniques for complex survey designs

Singh et al. ([13]) pointed out that the Randomized response (RR) technique proposed by Moors ([9]) is not desirable because it fails to protect the confidentiality of the respondents and they provided two alternative strategies free from the above drawback but limited to SRSWOR sampling only. In this paper, generalization of one of the strategies is provided for complex survey designs, wider class of estimators and for quantitative characteristics. Relative efficiency of the modified strategy is tested through empirical investigations. An erratum to this article is available at .
