Collaborative writing: Tools and tips  [cached]
Eapen Bell
Indian Journal of Dermatology, Venereology and Leprology , 2007,
Abstract: Majority of technical writing is done by groups of experts and various web based applications have made this collaboration easy. Email exchange of word processor documents with tracked changes used to be the standard technique for collaborative writing. However web based tools like Google docs and Spreadsheets have made the process fast and efficient. Various versioning tools and synchronous editors are available for those who need additional functionality. Having a group leader who decides the scheduling, communication and conflict resolving protocols is important for successful collaboration.

Abstract: Genome editing is considered as the most widely used approach of the present era. It had become a basic need of the current micro and molecular biological experiments. Gene engineering finds its widespread applications in medical, industry and agricultural sector. Unlike previous genetic engineering practices to insert or delete a part of genetic material at random place, genome editing allows the precise manipulation of DNA at a specific location. Zinc Finger Nucleases (ZFNs), Transcription Activator like Effector Nucleases (TALENs), Clustered Regularly Interspresed Short Palindromic repeats (CRISPR/Cas system) and meganucleases (recombinases) are the prime tools for editing an organism’s genome. Genome editing tools have an advantage to selectively delete or to integrate specific genes at specific loci. Use of recombinases for specifying site has further reduced time to integrate genes site specifically. Site specific gene stacking by the use of recombinases coupled with ZFNs, TALENs, or CRISPR/Cas genes have paved new pathways to target genes site specifically and to improve germplasm in lesser time than conventional breeding approaches.
Peer editing: a strategic source in EFL students' writing process
Colombian Applied Linguistics Journal , 2010,
Abstract: this article reports on a research project focused on peer editing as a pedagogical tool to promote collaborative assessment in the efl writing process. with teachers overstretched in the bogotá public school system, a method needed to be found that would allow students to receive much needed feedback without overtaxing the teachers' resources. peer editing, a phenomenon that often occurs naturally within the classroom, was therefore systematically implemented as a solution to the stated problem. the main aims of this study, conducted with a group of ninth grade student at a public school in bogotá, were to determine the role of peer editing in the writing process and to characterize the relationships built when students corrected each others writings. the instruments used for collecting data were field notes, video recordings and students' artifacts. the results showed that when students were engaged in peer editing sessions they created zones of proximal development in which high achiever students provided linguistic scaffolding and empowered low achievers. it was also found that students used thinking strategies such as noticing and explaining when they identified errors related to the formal aspects of the language.

Abstract: The article is devoted to the problem of expressive linguistic means in the fairy tales by Oscar Wilde. Much attention is paid to the stylistic functions’ analysis of the above-mentioned means and their role in the realization of the author’s intention. The idiosyncrasy of the author’s manner of writing is thoroughly investigated. The attempt to reconstruct the writer’s message is made.
On the Complexity of Multi-Parameterized Cluster Editing  [PDF]
Faisal N. Abu-Khzam
Computer Science , 2015,
Abstract: The Cluster Editing problem seeks a transformation of a given undirected graph into a disjoint union of cliques via a minimum number of edge additions or deletions. A multi-parameterized version of the problem is studied, featuring a number of input parameters that bound the amount of both edge-additions and deletions per single vertex, as well as the size of a clique-cluster. We show that the problem remains NP-hard even when only one edge can be deleted and at most two edges can be added per vertex. However, the new formulation allows us to solve Cluster Editing (exactly) in polynomial time when the number of edge-edit operations per vertex is smaller than half the minimum cluster size. In other words, Correlation Clustering can be solved efficiently when the number of false positives/negatives per single data element is expected to be small compared to the minimum cluster size. As a byproduct, we obtain a kernelization algorithm that delivers linear-size kernels when the two edge-edit bounds are small constants.

Abstract: Audio Video coding Standard (AVS) is established by the AVS Working Group of China. The main goal of AVS part 7 is to provide high compression performance with relatively low complexity for mobility applications. There are 3 main low-complexity tools: deblocking filter, context-based adaptive 2D-VLC and direct intra prediction. These tools are presented and analyzed respectively. Finally, we compare the performance and the decoding speed of AVS part 7 and H.264 baseline profile. The analysis and results indicate that AVS part 7 achieves similar performance with lower cost.
Effect of Dialogue Journal Writing through the Use of Conventional Tools and E-mail on Writing Anxiety in the ESL Context  [cached]

English Language Teaching , 2012, DOI: 10.5539/elt.v5n1p10
Abstract: ESL/EFL Anxiety has been reported as one of the foremost factors affecting ESL learners’ performance. Hence, identifying methods to assist language learners to alleviate their ESL anxiety deserve to be considered by the educators. This study compared the effect of dialogue journal writing (DJW) through two different modes of learning and teaching: conventional (using pen and paper or Microsoft Word) and online (using e-mail) on the writing anxiety. Forty-two students from an intact class undergoing the TESL program participated in the study. After going through seven weeks where students wrote their dialogue journals (using two different tools) in dyadic groups, pre and posttest writing anxiety questionnaire (Second Language Writing Anxiety Inventory) showed statistically no significant difference between groups in terms of writing anxiety, however mean scores revealed that e-mail group’s writing anxiety have been alleviated greater than their counterparts in conventional group. It shows e-mail has potential in assisting students in lowering their anxiety towards writing.
Integrating Social Networking Tools into ESL Writing Classroom: Strengths and Weaknesses  [cached]

English Language Teaching , 2012, DOI: 10.5539/elt.v5n8p42
Abstract: With the rapid development of world and technology, English learning has become more important. Teachers frequently use teacher-centered pedagogy that leads to lack of interaction with students. This paper aims to investigate the advantages and disadvantages of integrating social networking tools into ESL writing classroom and discuss the ways to plan activities by integrating social networking services (SNSs) into the classroom. Data was collected through an online discussion board from TESL students in a state university in Malaysia. The findings revealed that integrating social networking services in ESL writing classroom could help to broaden students’ knowledge, increase their motivation and build confidence in learning ESL writing. The students’ difficulties for concentrating on the materials when they use computer, lack of enough equipment as well as access to internet, and teachers’ insufficient time to interact with the students were regarded as the main disadvantages of integrating social networking tools into ESL writing classes. Therefore, in this new technological era, it is essential for students and teachers to be equipped with technical skills to be competent for life-long learning and teaching. More studies are needed to explore the teachers’ and students’ attitudes towards using ICT in ESL/EFL contexts. Future quantitative and qualitative studies with more participants are needed to provide deeper insight.
Collaborative Writing: Fostering Foreign Language and Writing Conventions Development  [PDF]
Elola Idoia,Oskoz, Ana
Language Learning and Technology , 2010,
Abstract: The use of social technologies, such as wikis and chats, has brought a renewed attention to L2 collaborative writing. Yet, a question that still remains to be answered is the extent to which learners’ writing is enhanced when using these tools. By analyzing learners’ individual and collaborative writing, this study (a) explores L2 learners’ approaches to the writing task in the wikis, (b) examines learners’ collaborative synchronous interactions when discussing content, structure and other aspects related to the elaboration of the writing task, and (c) describes learners’ perceptions of individual and collaborative writing and their impressions of the use of social tools in the FL writing class. Analysis of the data showed that while statistically significant differences were not evident in terms of fluency, accuracy and complexity when comparing the individual and collaborative assignments, there were observable trends that inform us about how learners’ interactions with the text differ when working individually or collaboratively. Further, an analysis of learners’ approaches to collaborative writing through the use of social tools shows that wikis and chats allowed them to concentrate on writing components in a different, yet complementary, manner depending on whether they interacted in the wikis or in the chats.

Abstract: Background: Three-dimensional printing (3DP) technologies are a trendsetting topic, also in the field of surgery. Preoperative planning for maxillofacial and neurological surgery, for instance, increasingly involves skull models obtained by 3DP. However, the cranial replicas currently used in this context have been shown to not reproduce the exact anatomy of the individual patient undergoing surgery. Objective: The present study aimed at investigating the extent to which manual editing, using current computer software tools, can improve skull models derived from medical images. Methods: Skull computed tomography (CT) was obtained on three cadavers and sent to three institutions that provide preoperative 3DP services. Each institute independently performed 3D reconstructions, including routine manual editing, and subsequently produced the replicas. The models were then qualitatively compared with the respective original skull. For quantitative comparison surface scans of particular regions of interest were made and the deviations assessed using 3-matic software (Materialise, Leuven, Belgium). Results: Routine manual editing of CT images resulted in replicas that were clear improvements over automatically generated reconstructions. This was particularly the case for teeth artefacts and thin-walled entities (e.g. paranasal sinuses). Conversely, however, many anatomical structures remained incorrectly rendered (e.g. orbitae, pterygoid processes, and sella turcica). Extraosseous calcifications had regularly not been removed. After extensive manual editing, however, replicas were able to provide largely submillimeter accuracy (mean deviation 0.2496 mm; standard deviation ±0.2276 mm). Conclusions: This study confirms that manual editing with current computer science tools does improve the quality of CT-based 3D printed skull models. But, it also demonstrates that a number of structures remain largely incorrectly rendered when edited in the presently used surgical framework. Conversely, it shows that highly accurate replicas are feasible, provided that extensive manual editing is performed.
