Bolstering the quality and integrity of online collaborative university- level courses via an open Sim standalone server in conjunction with sloodle

The contemporary era provides several challenges which extend from the reconstitution of an innovative knowledge domain and curricula to candidate learning platforms that support online course delivery methods. Educators and scholars on these demands have recently started to rethink alternative ways for the assimilation of the experiential knowledge in three-dimensional (3D) technologically advanced environments, like 3D multi-user virtual worlds. In spite the widespread dissemination and proliferation of novel educational implications by utilizing 3D multi-user virtual worlds combined with the 2D interface of LMS (Learning Management Systems) and the assessment of the effectiveness based on the online course delivery method in a long-term usability is still absent from the international academic literature. This study presents interoperability issues focused on the utilization of the virtual world Open Simulator (Open Sim) in conjunction with Sloodle (Simulation Linked Object Oriented Dynamic Learning Environment) as a free plug-in module. The evaluation of this online learning process according to an empirical research method became possible with the assistance of ninety-five (95) students by two different academic sectors that participated in this project and measured the capabilities and instructional affordances of this platform. The evaluation process was focused on four multi-dimensional parameters (psychological-pedagogical, technical-operational, organizational-financial, and socio-cultural). The study findings based on students’ experiences revealed that both platforms could be sufficiently connected as a unique platform which can increase the users’ learning abilities. This “hybrid” platform can adequately convert the ordinary multi-user virtual world of Open Sim and Sloodle in a common “incubator” of knowledge for online courses at university level. At the end, the instructional affordances and implications for future-driven directions are also discussed.     

Intra-Nationalization of Higher Education: The Hong Kong Case

This paper explores the internationalization of higher education initiatives of Hong Kong, being one of the Special Administrative Regions (SAR) of China, within the context of the Chinese Mainland-Hong Kong (CM-HK) relations. Historical, social, economic, and political ties between Hong Kong and the Mainland of China, their economic and political interdependency, and a time series analysis of Hong Kong’s University Grants Committee (UGC) statistical data (local and non-local participation, geographic composition, and cost analysis of UGC-funded programs) are used to support what the author calls the “intra-nationalization of higher education.” This forms a unique internationalization strategy, whereby a sub-national region such as Hong Kong and possibly Macau, orients its internationalization strategy towards a motherland, in this case China.     

题目：遗传改造细菌基因组的策略：基因定点突变、基因失活和基因过表达

With the availability of the whole genome sequence of Escherichia coli or Corynebacterium glutamicum, strategies for directed DNA manipulation have developed rapidly. DNA manipulation plays an important role in understanding the function of genes and in constructing novel engineering bacteria according to requirement. DNA manipulation involves modifying the autologous genes and expressing the heterogenous genes. Two alternative approaches, using electroporation linear DNA or recombinant suicide plasmid, allow a wide variety of DNA manipulation. However, the over-expression of the desired gene is generally executed via plasmid-mediation. The current review summarizes the common strategies used for genetically modifying E. coli and C. glutamicum genomes, and discusses the technical problem of multi-layered DNA manipulation. Strategies for gene over-expression via integrating into genome are proposed. This review is intended to be an accessible introduction to DNA manipulation within the bacterial genome for novices and a source of the latest experimental information for experienced investigators.     

An associative account of Orthographic Satiation in Chinese characters

Prolonged inspection of a Chinese character induces a feeling of uncertainty of the character, a phenomenon named as Orthographic Satiation. However, there has not been direct evidence showing that such satiation does occur at the orthographic level. To investigate whether Chinese satiation occurs at the orthographic level or at other levels, the present study applies a speeded repetition priming paradigm to Chinese, which has been successfully used to examine Semantic Satiation in English. When judging whether a category name matched an exemplar word, participants showed gradually slower responses as the character standing for the category name was repeated, indicating the occurrence of satiation. However, repetition of a character without accessing its meaning, or repeated access to its meaning without repeating the character itself, did not elicit satiation. The results suggest Orthographic Satiation occurs not at the orthographic level, but at a level associating orthography and meaning during Chinese character reading.     

Towards Building Direct Educational Partnership: The Foundation of Shanxi University in 1902

The foundation of Shanxi University is a prime example of the collaborative efforts in higher education between the Chinese and British in late Qing China (1842–1912). Both sides made compromises, with the Chinese adapting their ideas of educational sovereignty, and the British agreeing to work under the supervision of the local government. Such a collaboration was made possible by the individual personalities of the two founders and their visions for China’s higher education. The dual structure of the university, with one department to teach Chinese learning and the other to teach Western learning, showed that, at a local and personal level, these officials and missionaries opted for direct cooperation, despite the myriad changes and upheavals following the Boxer Movement. In addition, by allowing foreign missionaries into critical roles in a government university, the principle of ti-yong dualism was gradually being adapted. The formation of Shanxi University not only demonstrates the dynamics of the Sino-Western educational relationship and the roles individuals played in it, but also stimulates reflection on China’s contemporary cross-border partnerships in higher education     

Thinking aloud together: A teacher’s semiotic mediation of a whole-class conversation about percents

How does classroom interaction support students’ apprenticeship into the ways of speaking, writing, and diagramming that constitute the practice of mathematics? We address this problem through an interpretative analysis of a whole-group conversation about alternative ways of solving a problem involving percent discounts that occurred in a sixth grade classroom. This research study draws upon Dewey’s theory of inquiry, Vygotsky’s cultural–historical psychology, Freudenthal’s realistic mathematics education, and Halliday’s systemic functional linguistics (SFL). From Freudenthal, we borrow the notions of mathematizing and guided reinvention—the former notion offers a view of mathematics as an activity of structuring subject matter and the latter one provides insights into the processes whereby mathematizing is learned and taught in the classroom. We glean from Dewey his view of reflective thinking as inquiry and the role that conversations may serve therein. We rely upon Vygotsky’s notions of a verbal thinking plane and a social phase of learning in order to reconsider the function of whole-class interaction in apprenticing students into mathematizing. Finally, SFL provides us with tools for explaining the choices of grammar and vocabulary students and teachers make as they realize meanings in whole-group conversations. Treating the selected whole-class conversation as a text, we focus our analysis on how this text came to mean what it did. Our central questions are as follows: What meanings were realized in the whole-class conversation by teacher and students and how were these meanings realized? How did the teacher’s lexico-grammatical choices guide the students’ choices? In addressing these questions, we advance an interpretation of the conversation as paradigmatic of students and teacher thinking aloud together about percents.     

Individual performance across motoric self-regulation tasks are not correlated for pet dogs

Inhibitory control, the ability to restrain a prepotent but ineffective response in a given context, is thought to be indicative of a species’ cognitive abilities. This ability ranges from “basic” motoric self-regulation to more complex abilities such as self-control. During the current study, we investigated the motoric self-regulatory abilities of 30 pet dogs using four well-established cognitive tasks – the A-not-B Bucket task, the Cylinder task, the Detour task, and the A-not-B Barrier task – administered in a consistent context. One main goal of the study was to determine whether the individual-level performance would correlate across tasks, supporting that these tasks measure similar components of motoric self-regulation. Dogs in our study were quite successful during tasks requiring them to detour around transparent barriers (i.e., the Cylinder and Detour tasks), but were less successful with tasks requiring the production of a new response (i.e., A-not-B Bucket and A-not-B Barrier tasks). However, individual dog performance did not correlate across tasks, suggesting these well-established tasks likely measure different inhibitory control abilities, or are strongly influenced by differential task demands. Our results also suggest other aspects such as perseveration or properties of the apparatus may need to be carefully examined in order to better understand canine motoric self-regulation or inhibitory control more generally.     

Fathers’ roles in the process of talent development

In the process of children’s talent development, fathers have been largely ignored compared to mothers who are mostly identified as the initial and primary influence for their children. Though modern fathers are becoming more engaged in childrearing and interacting more with their children and changes in family systems lead to new challenges and demands for defining parental roles today, fathers are still predominately portrayed as the principal breadwinners of families. Literature including both empirical and anecdotal data has documented positive and promising outcomes of paternal involvement for children’s talent development though fathers’ roles are not always differentiated from mothers’ roles and little research studied fathers and gifted children, exclusively. This paper includes a comprehensive review of fathers’ contributions to children’s talent development and discussion about issues and suggestions for research involving fathers and talent development.
