Teacher satisfaction in online education: a two-factor model of extrinsic and intrinsic factors across diverse contexts
No full textBlended learning modes are becoming the norm in educational institutions. This research investigates the factors affecting teacher satisfaction with online lesson delivery. This study was undertaken in primary, secondary, and higher education institutions across ten countries worldwide. A total of 247 teachers responded to the survey. This work innovatively validates a two-factor model of teacher satisfaction with online teaching, grounded in Herzberg’s two-factor theory. A first-order confirmatory factor analysis (CFA) was used to validate the constructs, followed by a second-order exploratory factor analysis (EFA) to identify key drivers of teacher satisfaction. The results showed that there were two key hidden drivers of teacher satisfaction i.e., intrinsic factor and extrinsic factor. The two factors explained 75% of the variance in teacher satisfaction. Teachers reported higher satisfaction due to the flexibility and work-life balance that online teaching affords, while dissatisfaction stemmed from institutional policies and insufficient incentives. It was observed that STEM teachers and older educators had lower satisfaction and higher technology anxiety. These insights have potential applications beyond online teaching, extending to teacher satisfaction in physical classroom settings
Novel Machining Configuration of Carbon Fibre Reinforced Polymer (CFRP) Using Wire Electric Discharge Machining (WEDM)
No full textAdvanced aerospace materials like Carbon Fiber reinforced polymer (CFRP) contains heterogeneous and anisotropic material characteristics that does not exhibit sufficient toughness before failure. CFRP materials are recently replacing most of the modern applications like aerospace, space exploration and in various exotic engineering applications due to their outstanding strength to super lightweight properties. Manufacturing operations like cutting and machining the CFRP to the required shapes are most challenging aspects that are addressed in recent times. Aim of this research is to investigate the influence of CFRP orientation and layering pattern when machined using WEDM Machining process. As the material is extremely capable, and its heterogeneous structure makes them stand out from other conventional materials investigating its machinability using WEDM is vital. WEDM is extremely capable and could produce parts with intrinsic cuts and high precision. The various parameters involved with WEDM are carefully studied along with the novel metal-CFRP-metal sandwich configuration to machine and the CFRP samples are experimented with these parameters. The results obtained from the research are analyzed and the best suitable combinations of WEDM parameters are determined. To facilitate this, the cut samples are observed under a microscope to closely inspect the samples to discover which parameters had influenced the smoothness and quality of the cut the most.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Reverse Engineering – an Educational Tool for Sustainable development: Curriculum Enhancement Internship Project funded by the Teaching and Learning Academy
No full textEngineering as other subjects in Education needs to produce industry-oriented graduates. However, to graduate industry-ready engineers requires more active learning than passive knowledge.
To improve students’ experience, enhance their active learning and increase their engagement with the module being taught, project-base learning was introduced at foundation level, using reverse Engineering (RE) alongside with fundamental understanding sustainability as an induction to the sustainable development goals. Reverse Engineering is used in all industries, where companies would buy competitors’ products and disassemble them with the aim to study all components, the way they were made, the materials used and the manufacturing processes involved in their making. A detailed report is produced, then a plan is set up to improve each component and the product as whole, then, add differentiating values to companies’ own products.
To become sustainable, we should understand existing machines and search for ways to make them sustainable; e.g. converting diesel trains into hydrogen trains. It is clear that reverseengineering and reverse-manufacturing will play a key role in becoming sustainable societies.
In this project, series of RE lectures were given, however the remaining of the learning was left unstructured as are the problem in real industry. Students were given full ownership of the learning, with some key points to report on. Students engaged fully with the module, and this approach to learning has attracted a great number of students at level 3 and 4 who expressed their preference to way of active learning. This unveiled the challenge/lack of understand technical engineering terminologies.
To achieve a sustainable development especially Net-Zero, by the time set by policy makers, engineering is the key driver and RE will play a pivotal role, because to become efficient in absolute terms (energy, material, environment), all existing machines and manufacturing systems need to be revisited and re-engineered by our current and future engineers.
This project has a vision to make teaching and students sustainability tools and ambassadors by investigating into the extent to which we can teach RE to students to solve sustainability problems, and how we could integrate these aspects into teaching.

Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
