从此岸到彼岸——从台湾、大陆六年级(下)最后一篇课文说起

朋友给我带了一套台湾康轩版的《国语》教材和《习作》。《国语》就是我们的《语文》,《习作》则接近我们的苏教版配套练习册、补充习题的性质。稍稍粗犷一些的孩子,每当学期过半,他们的练习册就唇齿不依了。老师们总是单面胶、双面胶、剪刀不离办公桌,批改兼修补。而面对这和教材一样美丽儒雅、低调奢华的练习册,我极羡慕。细读内容,更如一个深潭,把我吸入,引发我对汉语的诸多联想。汉语是中华民族的母语。中华民族悠久的历史、几千年积累下来的优秀文化传统主要是靠语言文字传递下来的。同根同族的华人教育历来重视语文教学,因为其中涵盖着工具价值和文以载道的教育价值,同为母语教学,差距在哪？

Online object detection and recognition using motion information and local feature co-occurrence

An object learning and recognition system is implemented for humanoid robots to discover and memorize objects only by simple interactions with non-expert users. When the object is presented, the system makes use of the motion information over consecutive frames to extract object features and implements machine learning based on the bag of visual words approach. Instead of using a local feature descriptor only, the proposed system uses the co-occurring local features in order to increase feature discriminative power for both object model learning and inference stages. For different objects with different textures, a hybrid sampling strategy is considered. This hybrid approach minimizes the consumption of computation resources and helps achieving good performances demonstrated on a set of a dozen different daily objects.

Dealumination kinetics of composite ZSM-5/mordenite zeolite during steam treatment: An in-situ DRIFTS study

To get a better understanding of structural deactivation of ZSM-5/MOR during the catalytic cracking of n-heptane in the steam atmosphere, a comprehensive mechanism of hydrothermal dealumination was proposed through in-situ diffuse reflectance Fourier transform infrared spectroscopy(DRIFTS) in this work. The mechanism can be divided into two steps: firstly, the hydrolysis of four Al\\O bonds, and secondly, the self-healing of Si\\OH bonds accompanied with partial condensation of the extra-framework Al species. Accordingly, the kinetics of dealumination process has also been fully discussed. In the IR spectra, the range of 3450–3850 cm^(-1) could be deconvolved to distinguish the hydroxyl groups on the different position and calculate the consumption of each hydroxyl group during the reaction. Based on results from the in-situ DRIFTS, the kinetics of dealumination was hence developed and also in well agreement with the kinetics of deactivation of ZSM/MOR catalysts during the reaction in the presence of little coke deposits.

Genomic selection methods for crop improvement:Current status and prospects

With marker and phenotype information from observed populations, genomic selection （GS） can be used to establish associations between markers and phenotypes. It aims to use genome-wide markers to estimate the effects of all loci and thereby predict the genetic values of untested populations, so as to achieve more comprehensive and reliable selection and to accelerate genetic progress in crop breeding. GS models usually face the problem that the number of markers is much higher than the number of phenotypic observations. To overcome this issue and improve prediction accuracy, many models and algorithms, including GBLUP, Bayes, and machine learning have been employed for GS. As hot issues in GS research, the estimation of non-additive genetic effects and the combined analysis of multiple traits or multiple environments are also important for improving the accuracy of prediction. In recent years, crop breeding has taken advantage of the development of GS. The principles and characteristics of current popular GS methods and research progress in hese methods for crop improvement are reviewed in this paper.

An interpretation of alienation theme in J. D. Salinger＇s The catcher in the rye and Nine stories

J. D. Salinger is an alienated writer, who alienates himself from the dominant society. He is unsocial in character and unconventional in behavior. His reclusion can be regarded as the behavioral presentation of his alienation. Salinger also portrays many alienated characters in his The catcher in the rye and Nine stories. These alienated characters include children, adolescents and adults. They alienate themselves from dominant social culture, groups and even themselves. According to the analysis of these alienated protagonists from autobiographical and historical perspectives, the root of their alienation lies in the conflict between their searching for the ideal love and the absence of such love in the dominant society. So comparing with enjoying substantial life, Salinger＇s works can arouse people＇s interest and give more concern to their spiritual life.

The Collaborative Study in the Form of Group Works

Over the past decades, the rapid development has taken place in the teaching and research of English writing throughout the nation. However, due to the drawbacks in traditional teaching of English writing, especially the lack of effective information input （EII）, it is not an easy task for students to improve their writing level in conventional classes. This paper focuses on the study on group work from the perspective of information input. Unlike previous research, this paper intends to demonstrate the role of group work in obtaining effective information input. It starts with a brief introduction to problems in traditional teaching of English. Then it states the definition of group work and the ZPD theory applied in the paper. In the third part, it proposes a case study to testify how group work may improve the effective information input and terminate the study with the conclusion that group work can help to enhance students＇ effective information input. Based on the results of the study, we may suggest that applying group work in an English writing class will finally help students to elevate their writing level.

Reaching proficiency in laparoscopic splenectomy

AIM:To investigate the proficiency level reached in laparoscopic splenectomy using the learning curve method.METHODS:All patients in need of splenectomy for benign causes in whom laparoscopic splenectomy was attempted by a single surgeon during a time period of 6 years were included in the study (n=33). Besides demographics, operation-related variables and the response to surgery were recorded. The patients were allocated to groups of five, ranked according to the date of the operation. Operation duration, complications, postoperative length of stay, conversion to laparotomy and splenic weight were then compared between these groups.RESULTS: There was a significant difference regarding operation times between the groups (P = 0.001). An improvement was observed after the first 5 cases. The learning curve was flat up to the 25th case. Following the 25th case the operation times decreased still further. There was no difference between the groups regarding the other parameters.CONCLUSION: Unlike the widely accepted "L" shape, the learning curve for laparoscopic splenectomy is a horizontal lazy "S" with two distinct slopes. Privileges may be granted after the first 5 cases. However proficiency seems to require 25 cases.
