Syllabus design in a post-method age
No full textIn the 1970s and 1980s, the field of Syllabus Design was a focus area for research in both second language acquisition and language use in social contexts. The elaboration of new and more effective syllabuses was considered as the likely outcome of theoretical and empirical work, and the key to improving second or other language learning in schools and universities. This programme of research and development did not deliver on this promise, and syllabus design has faded as a focus of enquiry. This paper explores the reasons for this, and documents current practices in putting programmes together. The challenges of syllabus design have been left to teachers, and in the final section, some considerations for teachers to work with in designing their programmes are outline
Proceedings of the 2nd International Conference on Civil Engineering for Sustainability and Disaster Resilience
Get PDFThis book covers a wide range of topics, including sustainable infrastructure development, disaster risk reduction, climate change adaptation, and resilient construction practices. The "International Conference on Civil Engineering for Sustainability and Disaster Resilience" (ICCESDiRe 2024) proceedings book presents a collection of cutting-edge research and innovative practices in civil engineering aimed at promoting sustainability and enhancing disaster resilience. The proceedings also feature discussions on the integration of sustainable development goals (SDGs) into civil engineering practices, emphasizing the need for interdisciplinary approaches and stakeholder engagement. Overall, this proceedings book serves as a valuable resource for researchers, practitioners, and policymakers interested in advancing sustainable development and disaster resilience through civil engineering. It provides insights into current trends, challenges, and opportunities in the field, offering practical solutions and strategies for building a more sustainable and resilient future
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Influence of pH on the anaerobic fluidised bed reactor performance for palm oil mill effluent treatment
Get PDFThe effect of pH on the performance of a pilot-scale anaerobic fluidised bed reactor (AnFBR) was studied using palm oil mill effluent (POME) as the substrate. The performance of the 2000-litre reactor at different operating conditions, such as organic loading rates and retention times was studied. This acidic agro-industrial wastewater (pH 4.0–5.0) was neutralised by adding slacked lime. It was observed that, within 12 hr of hydraulic retention time (HRT), the AnFBR removes as high as 85 of the substrate chemical oxygen demand (COD) at a loading rate of 4 kg/m3 day. High pre-treatment cost is needed to neutralise the bulk volume of wastewater that was generated from the palm oil industries. Thus, an attempt was made to study the performance of the AnFBR under pH shock load. The influent pH was increased to 9.2 and then dropped around 5.0 to intensify the effect of the pH shock load. At shock load, the reactor performance for COD removal dropped by about 25 lower than the optimum condition. The maximum and minimum COD removal rates during the short period of continuous shock load were 60 and 56.5, respectively. The average effluent pH remained steady at around 6.1. From the analysis, it was revealed that the anaerobic fluidised bed had the buffering ability and was capable of treating POME with moderate removal efficiency at an influent pH of 5.0
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
