How to effectively manage and use Weibo comment information has become a research focus in the field of information content security. Three main tasks involved are emotion sentence identification and classification,emotion tendency classification,and emotion expression extraction. Combining with the latent Dirichlet allocation(LDA) model,a Gibbs sampling implementation for inference of our algorithm is presented,and can be used to categorize emotion tendency automatically with the computer. In accordance with the lower ratio of recall for emotion expression extraction in Weibo,use dependency parsing,divided into two categories with subject and object,summarized six kinds of dependency models from evaluating objects and emotion words,and proposed that a merge algorithm for evaluating objects can be accurately evaluated by participating in a public bakeoff and in the shared tasks among the best methods in the sub-task of emotion expression extraction,indicating the value of our method as not only innovative but practical.展开更多

Each of the sharing sub-keys may be a stochastic noise image or a significative image with no information on the original key. But a mass of sub-keys have to be saved actually, which faces the problem of inconvenient discrimination and management. This paper presents a visual cryptography scheme based on the digital signature for image discrimination and management, applying the digital signature and the time-stamp technology to the visual cryptography scheme. The scheme both solves the problem on the storage and management of the sharing sub-keys, increases the verification of image contents, thus enhances the validity of storage and management without security effect.展开更多

Accounting degrees convey traditional, technical and narrowly defined knowledge with limited scope for non conventional approaches. Sustainability accounting education has the potential to allow departure from the conventional thinking and practice in accounting education. Sustainability educated graduates are being increasingly expected by business and industry as sustainability education allows the fostering of ＂soft skills＂ that conventional accounting courses do not address. In spite of these potentials and needs for sustainability accounting education, less than a quarter of Australian and United States accounting faculties are offering a stand alone sustainability accounting course. There is a degree of uniformity in relation to course content with majority of focus on internal and external sustainability reporting. Other areas such as sustainability history in the context of accounting are not included in the courses. Sustainability is a complex area that needs more serious attention in accounting schools in order to match graduate attributes with the increasing industry demands.展开更多

The participants were 36 fifth graders in Taiwan. The researchers chose suitable picture books as teaching materials and made use of them to design a balanced reading program. The program combines the ideas of whole language and phonics rules. Whole-part-whole structure was used in the teaching process. The teaching of the balanced reading program lasted for nine weeks. The questionnaire of learning feedbacks, the questionnaire of reading activities, the teacher's journal, interviews with teachers and students were used to gather data. Six facts were found after the analysis of the data: (1) Among the picture books, 'Seven Blind Mice' and 'Snow' were chosen by the students as their favorite. (2) Most students liked the reading activities for this semester. (3) The students made progress in reading ability and reading techniques. (4) The frequency of the students' reading English storybooks increased. (5) Most students were willing to read English storybooks after the program. (6) The table of self-evaluation didn't work well. Some suggestions have been provided according to the findings.展开更多
