General University Requirements at Hong Kong Polytechnic University: evaluation findings based on student focus groups

Under the new four-year undergraduate programme, a general education framework titled ‘General University Requirements’ (GUR) has been developed and implemented since 2012/2013 at Hong Kong Polytechnic University (PolyU). To evaluate the implementation and effectiveness of the GUR in its first year, focus group interviews with students were carried out. In 13 focus groups, 62 first-year students from eight faculties/schools who took GUR subjects in 2012/2013 academic year were interviewed by trained researchers. Results showed that students generally had good perceptions of the GUR in terms of the subject content, teaching methods and the overall effectiveness of the subjects. The interactive teaching and learning initiatives adopted in GUR subjects were particularly appreciated, although students expressed minor concerns on the administration of GUR subjects. The results suggest that the first-year implementation of the GUR at PolyU was generally smooth and successful from the perspectives of the students.     

基于网络化考试条件下的考试管理改革探索

随着信息技术的迅速发展,计算机和网络在考试管理中的应用逐步深入,考试管理中出现了网络化考试形式。网络化考试具有组织管理高效、考试时间灵活、监考难度较小、组考成本较低等特点,在多方面给考试管理带来更为深刻的影响,要求考试管理机构做出相应变革,以便适应考试自身发展的需要。     

区域一体化对城市创新能力驱动研究——基于长三角的实证分析

长三角更高质量一体化发展标志着各种资源要素在长三角区域内的配置效率将进一步提升,有利于形成更强的区域创新能力。本文基于2005—2017年长三角城市统计数据,考察了区域一体化对城市创新能力的驱动作用,并对其中的影响机制和异质性进行了深入分析。结果显示：(1)区域一体化对长三角城市创新能力具有显著的促进作用。(2)机制分析发现,一体化伴随的产业集聚并未形成创新能力提升机制,但一体化推动的区域内部产业转移机制有效提升了城市创新能力。(3)异质性分析表明,长三角区域一体化对非核心城市、欠发达城市、低财政分权城市具有更为显著的城市创新能力驱动作用。

<Emphasis Type="Italic">Agrobacterium</Emphasis>-mediated transformation of herbicide resistance in creeping bentgrass and colonial bentgrass

Embryogenic calli were induced from the seeds of creeping bentgrass (Agrostis palustris Huds.) cv. Regent and colonial bentgrass (Agrostis Tenuis Sibth. Fl. Oxen.) cv. Tiger. The embryogenic calli were precultured on fresh medium for 4–7 days and then co-cultivated withAgrobacterium tumefaciens, LBA4404. which contains plasmid vector-pSBGM harboring bar coding region, synthetic green fluorescent protein (sGFP) coding region and matrix attachment region (MAR). After 3 days of co-cultivation, the calli were washed thoroughly and transferred to MS medium containing 2 mg/L of 2, 4-D, 12–15 mg/L phosphinothricin (PPT) and 250 mg/L of cefotaxime. After 2–3 months of selection, the actively growing calli of ‘Regent’ and ‘Tiger’ were transferred to MS medium with 12–15 mg/L PPT and 250 mg/L cefotazime for regeneration. The putative transformants were maintained on MS medium with 3 mg/L PPT for long period but control died within 1 month. After establishing in greenhouse, the transformants also showed strong resistance to 0.4% of herbicide Basta but control plants died within 2 weeks. Under confocal microscope, both young leaves and roots showed significant GFP expression. PCR analysis revealed the presence of a DNA fragment of GFP gene at the expected size (380 bp) in the transformants and its absence in a randomly selected control plant.
