为了探讨以MPG1基因作为启动子能否驱动GFP基因在大丽轮枝菌中表达,采用根癌农杆菌介导的真菌遗传转化方法,将含有MPG1-eGFP表达盒的pHMG载体转化入棉花大丽轮枝菌T-9中。经抗生素筛选后转化子约80个/106孢子,荧光显微镜观察转化子菌株孢子和菌丝在荧光显微镜下均发出绿色荧光,基因组DNA-PCR检测、GFP蛋白westernblot检测表明,GFP蛋白在大丽轮枝菌转化子中成功表达。结果表明,MPG1基因作为启动子成功驱动GFP基因在大丽轮枝菌中转录表达。  相似文献

Research into unsupervised ways of stemming has resulted, in the past few years, in the development of methods that are reliable and perform well. Our approach further shifts the boundaries of the state of the art by providing more accurate stemming results. The idea of the approach consists in building a stemmer in two stages. In the first stage, a stemming algorithm based upon clustering, which exploits the lexical and semantic information of words, is used to prepare large-scale training data for the second-stage algorithm. The second-stage algorithm uses a maximum entropy classifier. The stemming-specific features help the classifier decide when and how to stem a particular word.  相似文献

People still use documents in many everyday government processes. From tax payments to passport requests, citizens have to interact with low-interactivity information artifacts such as reports, maps and datasets, among many others. Despite efforts to improve information delivery in the public sector, effective information usage remains a critical topic of action and research. The user experience of government documents has rarely been assessed, despite them being regularly published and frequently used. Considering this, the two following research questions arise: 1) How can government documents be classified (or grouped) in terms of user experience? 2) How can the user experience of government documents be monitored over time in order to inform design decisions? Working with a public agency in Chile, we develop and test a classification and monitoring framework based on two online surveys (N?=?338 and N?=?298). We then propose a framework for understanding user experience of government documents in these three dimensions: interaction goal, volume of information and ease of understanding. Using a graphical representation to classify user experience provides greater visibility of the current status of information produced by a public organization. Furthermore, by monitoring the user experience of a government document at different times, organizations can understand the effect of their design decisions and improve their service quality by implementing user-centered processes.  相似文献

This study investigated development of the Big Five personality traits from early childhood into adulthood. An initial group of 137 Swedish children were assessed eight times between ages 2 and 29 years. Initial decreases in extraversion leveled off in early adulthood; agreeableness and conscientiousness increased from ages 2 to 29; neuroticism initially increased, leveled off in later childhood and adolescence, and decreased throughout early adulthood; while openness to experience showed an initial increase, then decreased and leveled off in early adulthood. Individual developmental trajectories varied significantly, particularly in relation to gender. Personality traits became increasingly stable, and the fact that childhood scores predicted scores in adulthood indicated that personalities are fairly stable across this portion of the life span.  相似文献

The aim of this study is to analyse how graphicacy is promoted through activities with images of the human body in third to sixth year primary school textbooks from three different publishers. The analysis was based on categories related to type of image, type of task, procedures, cognitive processing level required and whether there are explicit instructions on how to use the image. The results show that illustrations and visual diagrams are the most frequent images. The main task is image interpretation, whereas production tasks are scarce. Moreover, the tasks are not evenly distributed among the different procedures. The processing level required is low and requires superficial processing of the images, resulting in a learning process based on copy and repetition. There is some evidence of activities being sequenced according to educational level. We conclude that the kind of graphicacy found in the textbook activities is insufficient for acquiring competence in the use of images.  相似文献
