| 1 | 职业科学与职业教学论研究的起源显示文摘对于职业科学与职业教学论的研究始于对职业活动与工作岗位的分析,其对象是教育视阈下的职业及其业务领域、与职业相关的工作及工作过程。企业职教机构、职业学校的相关研究早于大学,形成了最初的职业科学思想萌芽以及独特的研究方式。大学的相关研究伴随职教师资培养展开,强调职业与教育互为背景,关注教学论与方法论研究。不同层次、类型的研究群体相互交流合作,为开发具有典型意义的研究方法提供了可能。未来将更多地关注特殊领域研究,并呈现跨学科、多样化、结构化的趋势。 | Joerg-Peter Pahl(德) 姜大源(译) | 2006 | 职业技术教育2006,27,28: | 13 |
| 2 | 硫喷妥钠抑制离体人单个核细胞分泌前炎症性细胞因子显示文摘目的 体外研究硫喷妥钠对离体人单个核细胞前炎症性细胞因子的影响。方法 抽取健康志愿者外周静脉血50ml,以密度梯度离心法提取其中单个核细胞,除阴性和阳性对照外,分别以100、400和1000μg/ml硫喷妥钠共同培养24h,收获前1h给予诱导物豆蔻酰佛波醇乙酯(PMA)或肿瘤坏死因子α(TNF-α)。通过酶联免疫吸附实验或化学荧光免疫吸附实验分析并比较细胞因子含量。结果 100、400和1000μg/ml硫喷妥钠使PMA诱导的IL-2分别从(511±320)pg/ml减少至(207±244)、(41±24)和(22±12)pg/ml,使IL-6从(270±293)pg/ml减少到(104±101)、(29±38)和(14±16)pg/ml,而TNF-α诱导的IL-8由(118±37)pg/ml减少为(40±14)、(24±11)和(12±19)pg/ml,以上改变均有统计学差异。结论 硫喷妥钠在体外呈剂量依赖性抑制人单个核细胞分泌前炎症性细胞因子IL-2、IL-6和IL-8。 | 刘志恒 张传汉 田玉科 HL Pahl | 2004 | 临床麻醉学杂志2004,20,4: | 6 |
| 3 | 运用卫星数据和来自国家森林清查的野外数据进行全国森林变量估计显示文摘瑞典约有55%的土地面积被森林所覆盖。目前,瑞典的森林覆盖没有统一的和地理学上明晰的描述。现存的独立性数据源是Landsat TM和SPOT HRV卫星数据、地图蒙片(map mask)和森林清查样地。它们在一起,使森林变量(如材积和林分年龄)的计算机估计成为可能。这些估计的精确度在像素水平上是低的,但在林分水平上较高。在规划木材资源应如何加以利用或出于监测目的时,这类基于栅格的森林数据对政府来说是有帮助的。本文描述了以有效成本建立森林变量估计全国数据库的生成流程。我们在林分水平上评价了瑞典西南部某地森林变量估计的精确度。结果表明,总材积估计的整体均方根误差为33%,年龄估计的整体均方根误差为23%。 | Heather Reese Mats Nilsson Tina Granqvist Pahlén Olle Hagner Steve Joyce Ulf Tingelf Mikael Egberth Hkan Olsson 王胜 | 2003 | AMBIO-人类环境杂志2003,32,8: | 4 |
| 4 | 参与式管理解决冲突:遥感和GIS用作瑞典北部驯鹿业土地利用需求信息交流的工具显示文摘在解决复杂的土地管理问题时,对短缺或者有争执的资源进行地理评估有助于不同利益相关者之间沟通认识和增进理解。本文中,我们说明如何使用遥感和GIS收集和汇总瑞典北部驯鹿放牧者和其他土地使用者(林业、采矿业、旅游业等等)的土地使用活动及使用模式的信息。该项目主要基于最终的土地使用者,即驯鹿放牧者们所做的工作,体现了面向土地使用者的新的努力。发展驯鹿业的土地利用规划的基础有以下几个方面:收集并数字化传统的驯鹿栖息地生态学和景观信息;将这些信息与来自野外调查及基于人造卫星观测的植被分类结果整合;绘制其他土地使用者的活动情况图。最终的土地利用规划提供的信息有利于驯鹿放牧者与其他利益相关者之间的磋商,并有助于驯鹿管理实施。该项目可作为一种大众参与和计划编制的模式,从而使本土信息和先进的遥感技术融入一个交互式的过程中。 | Per Sandstrm Tina Granqvist Pahlén Lars Edenius Hans Tφmmervik Olle Hagner Leif Hemberg Hkan Olsson Karin Baer Thomas Stenlund Lars Gran Brandt Mikael Egberth 周立志 程利群 | 2003 | AMBIO-人类环境杂志2003,32,8: | 4 |
| 5 | 100 GHz silicon–organic hybrid modulator显示文摘Electro-optic modulation at frequencies of 100 GHz and beyond is important for photonic-electronic signal processing at the highest speeds.To date,however,only a small number of devices exist that can operate up to this frequency.In this study,we demonstrate that this frequency range can be addressed by nanophotonic,silicon-based modulators.We exploit the ultrafast Pockels effect by using the silicon–organic hybrid(SOH)platform,which combines highly nonlinear organic molecules with silicon waveguides.Until now,the bandwidth of these devices was limited by the losses of the radiofrequency(RF)signal and the RC(resistor-capacitor)time constant of the silicon structure.The RF losses are overcome by using a device as short as 500 μm,and the RC time constant is decreased by using a highly conductive electron accumulation layer and an improved gate insulator.Using this method,we demonstrate for the first time an integrated silicon modulator with a 3dB bandwidth at an operating frequency beyond 100 GHz.Our results clearly indicate that the RC time constant is not a fundamental speed limitation of SOH devices at these frequencies.Our device has a voltage–length product of only V_(π)L=11 V mm,which compares favorably with the best silicon-photonic modulators available today.Using cladding materials with stronger nonlinearities,the voltage–length product is expected to improve by more than an order of magnitude. | Luca Alloatti Robert Palmer Sebastian Diebold Kai Philipp Pahl Baoquan Chen Raluca Dinu Maryse Fournier Jean-Marc Fedeli Thomas Zwick Wolfgang Freude Christian Koos Juerg Leuthold | 2014 | Light(Science & Applications)2014,3,1: | 3 |
