钦州湾表层海水温度盐度及pH值时空变化 总被引：2，自引：0，他引：2
根据2009年春夏秋冬4个季节调查资料,分析钦州湾表层海水温度、盐度及pH值的季节变化和分布特征。结果表明：钦州湾海水平均温度春季20．4℃,夏季30．1℃,秋季16．0℃,冬季14．6℃,变化特征与气温的季节变化相同,空间分布为夏秋季河口区的水温都略高于湾口区,而春冬季则相反。海水平均盐度春季20．067,夏季17．975,秋季23．864,冬季23．660,表现为秋季〉冬季〉春季〉夏季,各季节空间分布总体表现为河口区低,湾口区高的趋势。海水pH平均值春季7．82,夏季8．11,秋季8．01,冬季8．10,全年空间分布高值区均出现在大风江口外海域。钦州湾海水比较适宜大蚝、对虾、文蛤等广温广盐性品种的海水养殖。 相似文献

20世纪90年代我国区域高等教育公平与效率变化的实证研究 总被引：5，自引：0，他引：5
公平和效率是各国高等教育发展中存在的重要问题之一。一般认为公平和效率在理论上和宏观上是可以统一的，并能够得到协调发展和可持续发展。然而，从微观和实践层面上分析却往往会发现存在一种矛盾现象，似乎是一个不可调和的两难问题。我国省(市)高等教育发展的公平与效率就是当前急需关注的一个典型的、具体的问题。通过对反映我国1999年和2000年各省(市)高等教育和经济发展状况的多指标进行聚类、相关等统计分析，考察了我国20世纪90年代高等教育区域公平和效率的发展变化特征，并通过对二者量化关系的揭示，对我国省(市)20世纪90年代高等教育公平与效率问题进行了实证分析和评估，并对我国未来省(市)高等教育的进一步发展提出了相应的对策和建议。 相似文献

自18世纪中叶到20世纪中叶,北京话旁称代词系统在句法、语义上呈现出了比较明显的发展变化,这种发展变化在三个时期的三部典型的北京话文献《红楼梦》《儿女英雄传》《正红旗下》中得到了充分的反映。就旁称代词系统而言,历时嬗变的发生轨迹是：由18世纪中叶的＂别人、人家、别人家、他人、旁人＂阵容切换到了19世纪中叶的＂人家、别人、他人、旁人＂阵容,并最终切换到了20纪中叶的＂别人、人家＂阵容,期间的此消彼长、删汰整合昭然。就旁称代词个体而言,历时嬗变的发生轨迹是：1.＂别人＂由18世纪的炙热到19世纪的没落,再到20世纪的重新走强;2＂.人家＂由18世纪的初露锋芒到19世纪的首度大大超越＂别人＂而一枝独秀,再到20世纪与＂别人＂的平分天下;3＂.他人＂这个曾经在相当长的时段内的旁称代词家族的宠儿由18世纪的颓势已现到19世纪的英雄末路,直至20世纪的难觅踪影;4.不温不火一路走来的＂旁人＂由18世纪的衰落到19世纪的走向没落,直至20世纪的淡出我们的视线;5.产生于元代的＂别人家＂由18世纪的衰弱到19世纪的没落,直至20世纪的只留存在部分方言中而在北京话中彻底消亡。 相似文献

Utilizing 2068 individuals in 60 organizations in the U.S. and Italy, this study (a) examines the overall relationship between trust in top management and immediate supervisor and overall estimates of satisfaction and perceived organizational effectiveness, (b) compares the amount of variance in satisfaction and effectiveness that can be explained by trust in top management to the amount of variance explained by trust in immediate supervisor, and (c) clarifies the role of information receiving as a predictor of trust in top management and immediate supervisor. Results of a canonical correlation analysis indicated that the canonical equation explained 49% of the variance in the linear composites (Canonical R = .69, p < .001). Trust in top management was more strongly associated with satisfaction and effectiveness than was trust in immediate supervisor. Tzvo separate multiple regression analyses indicated that after controlling for geographic location of company and type of industry, information received about job and organizational issues uniquely explained 26% of the variance in trust in top management and 13% of the variance in trust in immediate supervisor. 相似文献

The aim and objective of this study is to examine and compare how schools in Galway, Republic of Ireland and Derry in the North of Ireland (cities located within two independent jurisdictions in Ireland) manage and respond to bereavement. To carry out a survey of schools, the ‘Loss in Schools’ questionnaire is considered the most suitable tool. The questionnaire, which contains 10 questions designed to unearth pertinent issues including the needs and concerns of schools, had previously been administered in studies in Hull. Sixty questionnaires were administered in both Galway and Derry, with a return of 38 and 35, respectively. This study illuminates important aspects of the topic. The schools in both Galway and Derry rate bereavement (and parental separation) as highly important in terms of priorities. In terms of policy, some of the respondents in both study sites report that loss is included in their school's policy documents but not formally included in the curriculum. A designated staff member (who would speak to the pupil experiencing the death of a family member or significant other) is evident in 37% of Derry schools and 23% of Galway schools. Some members of staff in both study sites have attended training in bereavement, although the courses are relatively short term. Schools request assistance from other agencies outside the formal schools arena in times of need. In Galway the psychology services are most commonly consulted, while in Derry the Western Education and Library Board Bereavement Counselling teams and Cruse Bereavement Care are identified as additional resources from which help is sought. This paper outlines recommendations on schools' training needs in the area of child bereavement and the request for support to help further develop and formalise school policies. 相似文献
