联机检索与传统咨询服务的结合

利用联机数据库进行情报资料检索怎样才能与传统的咨询服务结合起来呢?在回答这个问题之前,我们应当先弄清楚它们结合的真正含义。作者认为,这是指创造一种条件,即通过电子计算机网络利用其数据库,就象读者通过传统检索工具利用馆藏的印刷型和缩微型资料一样方便、迅速。     

3G运营:新商业模式与新生活

早在19世纪初期,美国的一位政治哲学家John C.Calhoun曾经说过:“旧事物的衰败与新事物的形成是一个转换过程,其中肯定会出现不确定、混乱、错误与盲从现象.“……     

以就业指导作为思想政治教育的切入点

高等教育由精英教育转为大众教育是发展的趋势与必然要求。我国高等教育1996年毛入学率为8．3％，到2002年达到15％，而1997年世界平均毛入学率17．8％，发达国家平均是61．1％，因此可以看到我国高等教育还处在世界发展水平的最初阶段。但由于我国人口基数大，在经过几年连续扩大招生规模后，我国高等教育进入了一个新的历史阶段，据教育部统计2001年全国高校毕业生为115万人，2002年达到了145万人，2003年为212万人，2004年将达到280万人，2005年将达到340万人。高校毕业生是我国人才资源的基础力量，     

The use of colours on the the seventeenth century royal warship Vasa

The seventeenth-century Swedish Royal warship Vasa was painted and decorated with almost 500 figure sculptures and many carved ornaments. It is probably the most extensive sculptural work in wood to have been preserved from this period in European history. The ship's decorations are of particular importance given the scarcity of knowledge of how sculptures in general, and large ships in particular, were painted in Northern Europe during this period. About 20 different pigments have been characterized and it has been possible to reconstruct the appearance of many of the sculptures and to extend this knowledge to the ship's original appearance.     

等待胜利

阿拉斯加湾将会复原，但是复原速速度不会太快。今年3月24日凌晨，埃克森公司的瓦尔德兹号油轮运载着120万桶原油驶向公海，在威廉王子湾的暗礁上搁浅，而阿拉斯加湾从那时起要从生态恶梦中恢复过来得花多长时间呢?该地区的动植物是否能够恢复其原有面貌呢?     

African American and European American children in diverse elementary classrooms: social integration, social status, and social behavior

With a sample of African American and European American 3rd- and 4th-grade children (N = 486, ages 8-11 years), this study examined classroom ethnic composition, peer social status (i.e., social preference and perceived popularity as nominated by same- and cross-ethnicity peers), and patterns of ethnic segregation (i.e., friendship, peer group, and cross-ethnicity dislike). African American--but not European American--children had more segregated relationships and were more disliked by cross-ethnicity peers when they had fewer same-ethnicity classmates. African American children's segregation was positively associated with same-ethnicity social preference and perceived popularity and with cross-ethnicity perceived popularity. European American children's segregation was positively associated with same-ethnicity social preference but negatively associated with cross-ethnicity social preference and perceived popularity.     

Hemoglobin, growth, and attention of infants in southern Ethiopia

Male and female infants from rural Ethiopia were tested to investigate relations among hemoglobin (Hb), anthropometry, and attention. A longitudinal design was used to examine differences in attention performance from 6 (M = 24.9 weeks, n = 89) to 9 months of age (M = 40.6 weeks, n = 85), differences hypothesized to be related to changes in iron status and growth delays. Stunting (length‐for‐age z scores < ?2.0) and attention performance, t(30) = ?2.42, p = .022, worsened over time. Growth and Hb predicted attention at 9 months, R² = .15, p < .05, but not at 6. The study contributes to the knowledge base concerning the relations among Hb, early growth, and attention.     

Computer-assisted remedial reading intervention for school beginners at risk for reading disability

The aim of the longitudinal study was to investigate whether a computer application designed for remedial reading training can enhance letter knowledge, reading accuracy, fluency, and spelling of at-risk children. The participants, 7-year-old Finnish school beginners (N=166), were assigned to 1 of 3 groups: (a) regular remedial reading intervention (n=25), (b) computer-assessed reading intervention (n=25), and (c) mainstream reading instruction (n=116). Based on the results, computer-assisted remedial reading intervention was highly beneficial, whereas regular type of intervention was less successful. The results indicated that at-risk children require computer-based letter-name and letter-sound training to acquire adequate decoding and spelling skills, and to reach the level of their non-at-risk peers.
