1风险态度与教育和职业选择行为--一个实验方法的研究案例显示文摘本文介绍了作者关于风险态度与教育和职业选择行为的研究。该研究运用实验的方法,重点检验了风险态度测量的信度和效度,同时还检验了前景理论的部分假设在解释现代中国大学生群体的选择行为中的适用性和局限性。在此基础上,作者提供了建立在实验结果基础上的进一步研究的结论,并探讨了未来继续深入研究的方向。丁小浩 孙毓泽 Joop Hartog 2009北京大学学报(哲学社会科学版)2009,46,1:18
2A CATALOGUE OF THE SEAGRASSES OF CHINA显示文摘In this overall survey of the seagrasses of China 15 species are listed, eight of which are recorded for the first time. The Potamogetonaceae (subfamilies Zosteroideae and Cymodoceoideae) are represented by 10 species, and the Hydrocharitaceae (subfamilies Vallisnerioideae, Thalassioideae and Halophiloideae)by 5 species. Halophila ovalis (R.Br.) Hook, f. is represented by 2 subspecies. A key to the species based on vegetative and generative characteristics is presented.C.den Hartog 杨宗岱 1990Chinese Journal of Oceanology and Limnology1990,8,1:12
3预期收入、风险与教育选择——来自北京六所高校的经验证据显示文摘在教育经济学研究领域,传统的教育选择研究文献往往假定个体只考虑教育收益,忽视了投资风险的真实存在。已有文献对教育选择行为的预期假定存在较大差异,强加在个体身上的假定可能导致对教育选择行为的不正确推论,而使用个体主观预期数据替代这些假定能更准确地分析个体教育决策行为。采用2007年在北京六所高校所做的'研究生教育态度的调查',利用预期收入、风险数据对北京高校大学生的研究生教育选择问题进行的实证研究发现,预期收入对选择研究生教育有显著影响,而风险对教育选择的影响却不尽相同:收入风险对于教育选择的影响不明显,主观风险对选择研究生教育则有负效应。此外,还发现就业率是大学生决定是否进一步接受教育的重要因素,所学专业就业率越高,选择继续接受研究生教育的愿望越小。上述研究结果暗示,政府相关部门应定期公布劳动力市场数据,便于大学毕业生对收入和就业状况形成合理预期,从而对未来的教育作出理性选择,有效发挥人力资本的作用。廖娟 Joop Hartog 丁小浩 2013北京师范大学学报(社会科学版)2013,,2:8
4On tolerability and safety of a maintenance treatment with 6-thioguanine in azathioprineor 6-mercaptopurine intolerant IBD patients显示文摘AIM: To determine the tolerability and safety profile of a low-dose maintenance therapy with 6-TG in azathioprine (AZA) or 6-mercaptopurine (6-MP) intolerant inflammatory bowel disease (IBD) patients over a treatment period of at least 1 year.METHODS: Database analysis.RESULTS: Twenty out of ninety-five (21%) patients discontinued 6-TG (mean dose 24.6 mg; mean 6-TGN level 540 pmol/8×108 RBC) within 1 year. Reasons for discontinuation were GI complaints (31%), malaise (15%)and hepatotoxicity (15%). Hematological events occurred in three patients, one discontinued treatment. In the 6-TG-tolerant group, 9% (7/75) could be classified as hepatotoxicity. An abdominal ultrasound was performed in 54% of patients, one patient had splenomegaly.CONCLUSION: The majority of AZA or 6-MP-intolerant IBD patients (79%) is able to tolerate maintenance treatment with 6-TG (dosages between 0.3 and 0.4 mg/kg per d). 6-TG may still be considered as an escape maintenance immunosuppressant in this difficult to treat group of patients, taking into account potential toxicity and efficacy of other alternatives. The recently reported hepatotoxicity is worrisome and 6-TG should therefore be administered only in prospective trials.Nanne KH de Boer Luc JJ Derijks Lennard PL Gilissen Daniel W Hommes Leopold GJB Engels Sybrand Y de Boer Gijsbertus den Hartog Piet M Hooymans Anja BU M(?)kelburg Barend D Westerveld Anton HJ Naber Chris JJ Mulder Dirk J de Jong 2005World Journal of Gastroenterology2005,11,35:4

8跟骨关节内移位骨折的功能疗效和患者满意度——切开复位、经皮手术和非手术治疗对比研究显示文摘对于跟骨关节内移位骨折,约60%的工薪阶层患者会选择切开复位内固定术(openreductionandinternalfixation,ORIF)治疗,术后恢复工作通常需要5~10个月,相当一部分患者1年内无法恢复工作;而对于保守治疗患者,骨折症状通常会持续1~2年,高达16%的患者需行关节内固定手术。本研究的主要目的是比较3种跟骨关节内移位骨折治疗方案——ORIF、经皮手术和非手术治疗的疗效差异。De Boer AS Van Lieshout EM Den Hartog D 叶翔凌 夏远军 2016中国骨科临床与基础研究杂志2016,8,6:2
