Do local and international school students in Hong Kong have different thinking styles?

This study had two objectives. The first objective was to investigate whether or not local and international school students in Hong Kong have different thinking styles. The second objective was to examine the predictive power of socialization variables for thinking styles among students in secondary schools. Three hundred and two students from three schools in Hong Kong responded to the Thinking Styles Inventory – Revised II based on Sternberg’s theory of mental style government, and a survey on two groups of socialization variables: student characteristic and school environment. The student characteristic variables included personological and situational variables, while the school environmental variables included in-class experience and assessment-related variables. Results indicated that there were statistically significant differences in thinking styles between local and international school students in Hong Kong. Results also indicated that the subgroup of in-class experience was the most powerful in predicting thinking styles at the international school, the subgroup of assessment-related variables was the most powerful in predicting thinking styles at the traditional local school, and the subgroup of personological characteristics was the most powerful in predicting thinking styles at the direct subsidy scheme local school. Implications of the findings are discussed for parents, teachers, school administrators and policy makers.published_or_final_versionEducationMasterMaster of Educatio

THE FORMULATION OF MICROEMULSION OF PLANT PROTECTANT, SPREADER, NEMATICIDE AND AGRICULTURAL CHEMICAL ON CONTROL OF PLANT ROOT-KNOT NEMATODE DISEASES

本發明係一種防治作物根瘤線蟲的微乳劑，其係包括重量佔整體微乳劑重量的20％~35％之肉桂油、重量佔整體微乳劑重量的30％~60％之苦茶皂素、重量係佔整體微乳劑重量的20％~50％之乙醇，該乙醇的濃度為 ％，該微乳劑在稀釋一萬倍以內仍能夠有效降低南方根瘤線蟲的發生率，且防治效果與一般有效的化學藥劑歐殺滅相當，再者，本發明之微乳劑的穩定性高，直接加水稀釋即可使用，因此不會對環境或土壤造成污染，且價格也較一般化學農藥低廉，非常具有市場競爭力

Identification of root-lesion nematode Pratylenchus penetrans and P. loosi (Nematoda: Pratylenchidae) from strawberry and tea plantations in Taiwan

自2007年10月起，以改良式柏門氏漏斗分離法，從台灣的草莓和茶園主要產區中，總計採集到9群根腐線蟲(Pratylenchus spp.)，其中也草莓上所分離的5個種群皆鑑定爲P. penetrans (Cobb, 1917)Chitwood & Oteifa，1952，其餘來自茶樹的4個種群皆鑑定爲P. loosi Loof，1960。每一根腐線蟲種群之主鑑定依據爲光學顯微銳和SEM的形態特微觀察，以及形態測量值(morphometrics)的統計分析，立輔以包含完整5.8S基因和內轉錄區間ITS-1和ITS-2，以及部分18S和28S基因序列的核糖體DNA(ribosomal DNA, rDNA)片段序列的相似度比對分析。本研究已將P. penetrans和P. loosi的rDNA片段代表性序列錄於GenBank資料庫中，其序列大小分爲916bp和1238bp，而二者的序列相同度爲80.9%。 Nine populations of Pratylenchus spp. have isolated by modified Baermann funnel method from the major production area of strawberry and tea crops in Taiwan since October, 2008. Comparisons of the morphology, morphometrics and ribosomal DNA fragment sequences, including full 5.8S gene, ITS-1, ITS-2 and partial l8S and 28S gene. 5 populations of nematode from strawberry were identified as P. penetrans (Cobb, 1917) Chitwood & Oteifa, 1952, the other 4 populations from tea were as P. loosi Loof, 1960. The lengths of representative sequences of rDNA fragment from P. penetrans and P. loosi was 916bp and 1238bp, respectively, with 80.9% similarity to each other, and have been submitted to GenBank
