“My Excellent College Entrance Examination Achievement” — Noun Phrase Use of Chinese EFL Students’ Writing

—Previous studies have shown that phrasal structure, particularly complex noun phrases with phrasal modifiers, is a feature of advanced academic writing. Therefore, it would be important for those who plan to pursue further studies to learn to write in the way that is appropriate for academic writing. Using the manual annotation function of UAM corpus tool, this study compared the noun phrase use of Chinese EFL students’ writing with that of proficient language users. This study also discussed the significant differences found between these two groups in terms of noun phrase use and their implications for EFL/ ESL writing instruction

Integrating Language, Content, Technology, and Skills Development through Project-based Language Learning: Blending Frameworks for Successful Unit Planning

In this article, the authors first summarize the literature on project-based language learning (PBLL), a sound approach to second language teaching, addressing its various benefits such as providing opportunities to develop language authentically in real-world contexts, building decision-making and problem-solving skills, and developing content knowledge. In acknowledging reports that have also suggested that students can struggle to see how language is being developed through PBLL, the authors then argue that by looking at a project as a social practice, educators can demonstrate how language, content, and 21st century skills can be taught as an integrated whole through PBLL. They describe two existing frameworks, Mohan’s (1986) knowledge framework and Beckett and Slater’s (2005) Project Framework, and illustrate how these can be combined to create unit plans that explicitly integrate language, content, skills, and technology. To illustrate the blending of the two frameworks, the authors present a unit plan that targets the content area of applying for American graduate schools. This unit plan offers eleven lessons that include teaching sequences, tasks, and learning objectives for the content, language, academic skills, and technological understandings that the unit comprises. The authors also detail how the combination of the frameworks led to the creation of the various lessons so that this process can be used as a model for creating future relevant unit plans

High performance extendable instruction set computing

In this paper, a new architecture called the extendable instruction set computer (EISC) is introduced that addresses the issues of memory size and performance in embedded microprocessor systems. The architecture exhibits an efficient fixed length 16-bit instruction set with short length offset and immediate operands. The offset and immediate operands can be extended to 32 bits via the operation of an extension flag. The code density of the EISC instruction set and its memory transfer erformance is shown to be significantly higher than current architectures making it a suitable candidate for the next generation of embedded computer systems. The compact EISC instruction set introduces data dependencies that seemingly limit deep pipeline and superscalar implementations. This paper suggests a mechanism by which these dependencies might be removed in hardware

Event-Driven Network Programming

Software-defined networking (SDN) programs must simultaneously describe static forwarding behavior and dynamic updates in response to events. Event-driven updates are critical to get right, but difficult to implement correctly due to the high degree of concurrency in networks. Existing SDN platforms offer weak guarantees that can break application invariants, leading to problems such as dropped packets, degraded performance, security violations, etc. This paper introduces EVENT-DRIVEN CONSISTENT UPDATES that are guaranteed to preserve well-defined behaviors when transitioning between configurations in response to events. We propose NETWORK EVENT STRUCTURES (NESs) to model constraints on updates, such as which events can be enabled simultaneously and causal dependencies between events. We define an extension of the NetKAT language with mutable state, give semantics to stateful programs using NESs, and discuss provably-correct strategies for implementing NESs in SDNs. Finally, we evaluate our approach empirically, demonstrating that it gives well-defined consistency guarantees while avoiding expensive synchronization and packet buffering

Strictosidine, the common precursor for monoterpenoid indole alkaloids with 3 α and 3 β configuration

Recently we reported that strictosidine (l> is the key intermediate in the formation of the three classes (ASDidOf3DeIm5, Iboga, Corynanthe) of monoterpenoid indole alkaloids In Catharanthus roseus and a variety of other plant species in cell culture using in vivo and in vitro techniques"2. These results were independently confirmed In Manchester 394 and subsequently also Scott et a1.5 were able to confirm the precursor role of (1) using Catharanthus material. All these results are in accord with reports on the biosynthesis of an alkaloid of taxonomically distant origin, camptothecln, for which strictosidine la&am6 was previously found to be a precursor, and recently7 also (1). The key intermediate in the biosynthesis of the majority of mono-terpenoid alkaloids is therefore (1) with 3 a (2) configuration, rather than vincoside (2) with 3 13 (lX> configuration as had previously been assumeda. However, a generalization of this precursor function of (1
