沿海地区设计潮位计算方法探讨 总被引:1,自引:0,他引:1
采用P-Ⅲ型分布及极值Ⅰ型分布,研究了沿海地区设计潮位计算方法.阐述了资料的一致性检验的方法.结合坎门站潮位资料,对比了两种方法的计算效果.结果表明,两种方法对不同重现期设计值的估计结果相当,但P-Ⅲ型分布计算时参数的选取与习惯用法不符,因此,建议采用极值Ⅰ型分布进行设计潮位计算. 相似文献

The object of the study was to investigate the significance of the differences between verbal and non-verbal scores on the New South African Group Intelligence Test (NSAGT).The experimental subjects were first year university students. They were subdivided into three groups: one group whose non-verbal scores were higher than their verbal scores, a second group whose verbal scores were higher than their nonverbal scores and a third group, acting as a control group, whose verbal and nonverbal scores were approximately equal.The three groups were compared with regard to such features as visual and auditory acuity, personal adjustment and academic achievement. The raw data were arranged in three-dimensional contingency tables and interrelationships between variables were computed by means of the G2 test.A positive correlation was found between temperamental personality features and high non-verbal scores on the NSAGT.This article is based on the MA dissertation of the second author under the supervision of the first author. The study was partly sponsored by a grant from the Human Sciences Research Council. Republic of South Africa, to which body grateful acknowledgement is made. However, the opinions expressed and the conclusions drawn are the absolute responsibility of the authors 相似文献

Phenolics, as the main bioactive compounds in tea, have been suggested to have potential in the prevention of various human diseases. However, little is known about phenolics and their bioactivity in Zhangping Narcissue tea cake which is considered the most special kind of oolong tea. To unveil its bioactivity, three phenolic-enriched extracts were obtained from Zhangping Narcissue tea cake using ethyl acetate, n-butanol, and water. Their main chemical compositions and in vitro bioactivity were analyzed by high-performance liquid chromatography (HPLC) and ultraperformance liquid chromatography-mass spectrometry (UPLC-MS). The ethyl acetate fraction (ZEF) consisted of higher content of phenolics, flavonoids, procyanidins, and catechin monomers (including epigallocatechin gallate (EGCG), epicatechin gallate (ECG), and gallocatechin gallate (GCG)) than n-butanol fraction (ZBF) and water fraction (ZWF). ZEF exhibited the strongest antioxidant capacity in vitro due to its abundant bioactive compounds. This was validated by Pearson correlation and hierarchical clustering analyses. ZEF also showed a remarkable inhibition on the growth, migration, and invasion of 4T1 murine breast cancer cells. 相似文献

The title of the 2014 Australian Teacher Education Association (ATEA) conference was Teacher Education, An Audit: Building a platform for future engagement. One of the conference themes was Professional Experience: What works? Why? I seized upon this theme and the title of the conference as it afforded me an opportunity to do an audit of my research in professional experience over the last 25 years. This article presents this evidence base and the messages I have taken from this evidence. I have done this in the hope that, by collating some of the insights gained from the past and the present, it will help to “build a platform for future engagement” in professional experience. In preparing this article I was asked by the Editors to reflect also on how I developed my distinctive line of inquiry and expertise in relation to the practicum across an extended period. These reflections are included. I hope they will support university-based teacher educators in enhancing their satisfaction and achievements from working in this stimulating and provocative field of study. 相似文献

OBJECTIVES: Since the late 1980s, there has been a strong theoretical focus on psychological and social influences of perpetration of child sexual abuse. This paper presents the results of a review and meta-analysis of studies examining risk factors for perpetration of child sexual abuse published since 1990. METHOD: Eighty-nine studies published between 1990 and April of 2003 were reviewed. Risk factors were classified into one of the following six broad categories: family factors, externalizing behaviors, internalizing behaviors, social deficits, sexual problems, and attitudes/beliefs. Sex offenders against children (SOC) were compared to three comparison groups identified within the 89 studies: sex offenders who perpetrated against adults (SOA), non-sex offenders, and non-offenders with no history of criminal or sexual behavior problems. RESULTS: Results for the six major categories showed that SOC were not different from SOA (all d between -.02 and .14) other than showing lower externalizing behaviors (d=-.25). Sex offenders against children were somewhat different from non-sex offenders, especially with regard to sexual problems and attitudes (d=.83 and .51). Sex offenders against children showed substantial differences from non-offenders with medium sized effects in all six major categories (d's range from .39 to .58). CONCLUSION: Child sex offenders are different from non-sex offenders and non-offenders but not from sex offenders against adults. PRACTICE IMPLICATIONS: This study suggests that the presence of general risk factors may lead to a variety of negative behavioral outcomes, including the perpetration of child sexual offending. Family factors were strongly related to the perpetration of child sex offending (vs. non-sexual offending or non-offending) and may be valuable intervention points for interrupting the development of child sex offending, as well as other negative behaviors. Other potential points for intervention may focus on the development of appropriate social and emotional skills that contribute to sexual offending. 相似文献

论农村土地政策在农村人力资源开发中的作用 总被引:1,自引:0,他引:1
在对我国丰富的农村人力资源的开发过程中 ,农村土地政策始终是一个关键因素。如果党和政府制定的农村土地政策符合农村人事矛盾的发展要求 ,它就会积极促进农村人力资源的开发与利用 ;反之 ,则会阻碍甚至破坏农村人力资源的正常开发与利用。在 2 1世纪我们必须贯彻正确的农村土地政策 ,保证农村人力资源的有效开发 ,积极促进农村社会经济的健康发展。 相似文献
