An Analysis of The Handwriting of Elderly Chinese Subjects.
Nowadays, one of the issues of concern that brought on by the aging population is legal disputes that have been increasing in number every year. One core problem in these legal disputes involves handwriting identification. There are however not many previous studies in China that have been concentrated on this field. Hence, the study on elderly Chinese subjects\u27 handwriting has an extremely broad potential value for its application for academic usage and practical meaning. This study uses an empirical technique, gathering first hand data and analysing them by employing proper methods. There are 7 handwriting features and characteristics that have been found in the study to represent the key characteristics of the elderly Chinese subjects\u27 handwriting. They are: Pen pressure, occurrence rate of traditional Chinese words, letter size, poor structure, tremor, half-way stop sign, and towing sign at beginning and end of strokes
An Exploration of Experiences of Low Socioeconomic Chinese Students Who Achieved High Scores on the National College Entrance Exam
Although the economy has been developing at a fast pace for the last few decades, there is still a relatively high low SES population within the Chinese society, which constitutes a contextual barrier to educational equity in Chinese education. Meanwhile, the Chinese government has been administering assistance policies in education to promote education equity, such as the milestone policy introduced by the Compulsory Education Law that requires all school-age children to attend grades one through nine for free. This policy has brought immense prosperity to the majority of citizens. However, Chinese education still faces a large array of challenges pertaining to the imbalanced development, funding shortages, lack of qualified educators, household registration system, family mobility, and so forth. These challenges compromise low SES students’ educational attainment and performance on high-stake tests, such as the National College Entrance Exam (NCEE). Considering the high value of the NCEE, understanding what factors affect low SES students’ performance on this test has a practical value to educational practices. School leaders and policy makers need to be informed and aware of these factors in order to more effectively support low SES students in the Chinese education system. Nonetheless, the influences of SES on test scores, especially the Chinese NCEE, remain largely unexplored in existing literature. The author aimed to use the findings of the study to inform Chinese policy makers, building-level leaders, and educators as to how to better support students from low SES families and eventually improve social justice and education equity in China. Regardless of the adverse situation, quite a number of low SES Chinese students still seized college education opportunities by excelling on the NCEE due to their extraordinary diligence and work ethics. In this context, the successful examples of low SES students on the NCEE is worthy of research to reveal what factors influenced their success on the NCEE. The research used individual interview to collect qualitative data and tried to explore the experiences of the low SES Students with high achievements. There were 18 participants joined this study. The findings from this study open a path, possible methods, and advice on how to replicate the participants in this study successful experience on a larger scale and to extend those benefits to a larger number of low SES students, their families, and their communities. Based on the findings, key factors for the success of the participants were already present during their pre-high school trajectories and before they have received any significant financial and educational benefits through the Hongzhi program. Therefore, the author focused on developing, strengthening, and multiplying those factors, rather than on the aspect of allocating financial resources, which nevertheless would be necessary to implement those proposals. Those financial resources, obviously, lay beyond the scope and purposes of the study. In other words, the author wanted to make ample use of already existing resources that may have not been used so far or are misunderstood, underused, and underestimated. Finally, the recommendations based on the findings of this study promote the development of a community approach to strengthening education by including schools, educators, families, and students whose combined efforts could benefit each of the stakeholders in a synergistic cycle. The author envisions that the process of helping low SES students to succeed in their education paths could in turn help to develop further the fabric of the local low SES communities. Thus, the process would help in transforming schools into community centers where everybody can take part in the multifaceted teaching process, in learning and in receiving the benefits of educational achievement, each giving and receiving according to their different roles, assets, and contributions, to the overall benefit of Chinese society
Challenges of Being a Chinese Principal: Practitioner Perspectives
This qualitative study examined how public-school principals spent their professional day, the challenges they faced, and their advice to new principals regarding how to respond to the challenges they identified. The themes that emerged from the data underscored the demands of high-stakes test preparation that the participants felt undermined education quality and stifled student creativity. The relationships across themes that emerged identified being a good teacher and life-long learner as essential to instructional supervision and maintaining one’s focus on raising the quality of student’s educational experiences. Demonstrating a good moral character was even more critical, however, to maintaining one’s priorities and serving as a role model for teachers and students
Anti-dendriform algebras, new splitting of operations and Novikov type algebras
We introduce the notion of anti-dendriform algebras as a new approach of
splitting the associativity. They are characterized as the algebras with two
operations whose sum is associative and the negative left and right
multiplication operators compose the bimodules of the sum associative algebras,
justifying the notion due to the comparison with the corresponding
characterization of dendriform algebras. The notions of anti--operators and anti-Rota-Baxter operators on associative algebras are
introduced to interpret anti-dendriform algebras. In particular, there are
compatible anti-dendriform algebra structures on associative algebras with
nondegenerate commutative Connes cocycles. There is an important observation
that there are correspondences between certain subclasses of dendriform and
anti-dendriform algebras in terms of -algebras. As a direct consequence, we
give the notion of Novikov-type dendriform algebras as an analogue of Novikov
algebras for dendriform algebras, whose relationship with Novikov algebras is
consistent with the one between dendriform and pre-Lie algebras. Finally we
extend to provide a general framework of introducing the notions of analogues
of anti-dendriform algebras, which interprets a new splitting of operations.Comment: 25 page

CML-MOTS: Collaborative Multi-task Learning for Multi-Object Tracking and Segmentation
The advancement of computer vision has pushed visual analysis tasks from
still images to the video domain. In recent years, video instance segmentation,
which aims to track and segment multiple objects in video frames, has drawn
much attention for its potential applications in various emerging areas such as
autonomous driving, intelligent transportation, and smart retail. In this
paper, we propose an effective framework for instance-level visual analysis on
video frames, which can simultaneously conduct object detection, instance
segmentation, and multi-object tracking. The core idea of our method is
collaborative multi-task learning which is achieved by a novel structure, named
associative connections among detection, segmentation, and tracking task heads
in an end-to-end learnable CNN. These additional connections allow information
propagation across multiple related tasks, so as to benefit these tasks
simultaneously. We evaluate the proposed method extensively on KITTI MOTS and
MOTS Challenge datasets and obtain quite encouraging results
Distinct Role of Rab27a in Granule Movement at the Plasma Membrane and in the Cytosol of NK Cells
Protocols were developed to automate image analysis and to track the movement of thousands of vesicular compartments in live cells. Algorithms were used to discriminate among different types of movement (e.g. random, caged, and directed). We applied these tools to investigate the steady-state distribution and movement of lytic granules (LG) in live natural killer (NK) cells by high-speed 3-dimensional (3D) spinning disc confocal and 2-dimensional total internal reflection fluorescence microscopy. Both mouse NK cells and a human NK cell line deficient in the small GTPase Rab27a were examined. The unbiased analysis of large datasets led to the following observations and conclusions. The majority of LG in the cytosol and at the plasma membrane of unstimulated NK cells are mobile. The use of inhibitors indicated that movement in the cytosol required microtubules but not actin, whereas movement at the plasma membrane required both. Rab27a deficiency resulted in fewer LG, and in a reduced fraction of mobile LG, at the plasma membrane. In contrast, loss of Rab27a increased the fraction of mobile LG and the extent of their movement in the cytosol. Therefore, in addition to its documented role in LG delivery to the plasma membrane, Rab27a may restrict LG movement in the cytosol
