Theoretical consideration of effect of fishing mortality on growth and reproduction of fish populations

Summary An increase in fish mortality due to fishing can theoretically change the growth and reproduction of fish populations from the viewpoint of adaptation. We address the issue of how an iteroparous fish should convert surplus energy into somatic growth and reproduction at each age under given conditions of mortality. A model of life history, which maximizes the net reproductive rate using the discrete maximum principle, is improved employing a new relationship between body weight and surplus energy which we have recently proposed. The model is applied to the North Sea plaicePleuronectes platessa, for which it has been reported that the average length of young fish had increased whereas that of old ones had decreased for some decades. Although the model cannot directly explain the former phenomenon, the two phenomena can be interpreted as a change in the optimal life history due mainly to an increase in mortality.     

家庭档案及其教育功能探析

家庭档案在人们社会生活中的重要作用日益凸显;就教育功能而言,突出地表现在家庭档案可以提供德智体、美育、心育等方面的教育内容;同时,家庭档案也是一种积极有效的教育手段:能促进自主学习与自我教育,有利于家庭积极参与社区教育和社会主义精神文明建设;能促进学校的教育教学工作,有利于家教合作。档案部门、家庭、学校等有关方面应积极协作,加强宣传力度,加强公众的档案意识,向公众提供建设家庭档案的业务指导,加强家庭档案的建设,以充分发挥其教育功能。     

用谦抑性原则检讨我国刑法对教唆未遂的处罚规定

刑法谦抑性原则的要义就是缩小刑事处罚的范围和减轻刑事处罚的程度。我国刑法第 2 9条第 2款规定 :“如果被教唆的人没有犯被教唆的罪 ,对于教唆犯 ,可以从轻或减轻处罚。”这表明我国刑法对教唆未遂采必罚主义 ,这种做法有违谦抑性原则 ,且不具有可操作性。因此 ,该条款应修改为 :“如果被教唆的人没有犯被教唆的罪 ,如果此罪的法定最低刑为三年以上有期徒刑 ,对于教唆犯 ,可以比照所教唆之罪从轻、减轻或免除处罚。     

Tree health mapping with multispectral remote sensing data at UC Davis, California

Tree health is a critical parameter for evaluating urban ecosystem health and sustainability. Traditionally, this parameter has been derived from field surveys. We used multispectral remote sensing data and GIS techniques to determine tree health at the University of California, Davis. The study area (363 ha) contained 8,962 trees of 215 species. Tree health conditions were mapped for each physiognomic type at two scales: pixel and whole tree. At the pixel scale, each tree pixel within the tree crown was classified as either healthy or unhealthy based on vegetation index values. At the whole tree scale, raster based statistical analysis was used to calculate tree health index which is the ratio of healthy pixels to entire tree pixels within the tree crown. The tree was classified as healthy if the index was greater than 70%. Accuracy was checked against a random sample of 1,186 trees. At the whole tree level, 86% of campus trees were classified as healthy with 88% mapping accuracy. At the pixel level, 86% of the campus tree cover was classified as healthy. This tree health evaluation approach allows managers to identify the location of unhealthy trees for further diagnosis and treatment. It can be used to track the spread of disease and monitor seasonal or annual changes in tree health. Also, it provides tree health information that is fundamental to modeling and analysis of the environmental, social, and economic services produced by urban forests.     

ETHNICITY, GENERATION, AND SCHOOL ATTAINMENT OF ASIANS, HISPANICS, AND NON-HISPANIC WHITES

Research on immigration and attainment in U.S. schools typically does not separate out generation of U.S. residence, a critical factor in attainment. This article explores immigrant generation effects (native, child of immigrant, immigrant) on schooling attained for Asians, Hispanics, and non-Hispanic whites, using Current Population Survey data. Previously unpublished cross-sectional data are presented. Regressions predicting school years completed show variable generation-by-ethnicity effects. Asian attainment increases sharply between immigrant and child-of-immigrant generations, leveling off thereafter. Hispanic attainment improves with successive generations of U.S. residence. Non-Hispanic white attainment peaks in the child-of-immigrant generation and declines for later generations.     

教育行动研究与在职外语教师的专业发展

教育行动研究作为一种解决现实课堂教学问题的实践方法和特殊的教师教育方法正受到越来越多的国内外教育研究者的关注。它倡导教师即研究者通过对自己课堂中的教学现象进行考察和研究并从中获取知识,改进教学质量。教育行动研究与教师专业发展密切相关。教育行动研究可以改进教学质量,提高教学水平,帮助在职教师重建知识体系,促使教师向专家型教师转化,是在职外语教师专业发展的可行的、有效的途径。     

Organization and implementation of China's national sampling survey on fertility and birth control

The Planning and Statistical Department of the State Family Planning Commission of China in July 1988 implemented a fertility and birth control survey in China on 2.16 million married women ages 15-57 using stratified, systematic, clustered, and non-proportionate sampling. 3 questionnaires were used: household, married women, and sample unit covering basic status, family planning status, general characteristics of pregnancy and contraception, population flow, deaths since 1981, and socioeconomic status. The authors suggest several international cooperative research projects including: design of fertility and contraception survey; Chinese population growth; Chinese population dynamics; dynamics of marital and family status; fertility; contraception and birth control; mortality; migration; status of the nationalities of China; population development; regional fertility status; and others. Data from the survey will be available in June 1989.
