University Teachers’ Perceptions of Their Work and the Qualities of Excellent Teachers in the Context of Emergency Remote Learning

The massive adoption of online learning during the COVID-19 pandemic brought an opportunity to investigate teachers' conceptions of excellent teaching in the context of emergency remote education. From June to August 2020, we conducted a cross-sectional study using an online questionnaire to (1) analyze teachers' perceptions of the quality of their teaching in the context of the COVID-19 pandemic, (2) identify teachers' perceptions of the qualities of excellent online teachers, and (3) examine differences based on gender, age, previous online learning training, and work experiences. The sample consisted of 341 university teachers who worked in private and public institutions in Ecuador. Results indicate that most participants perceived online teaching was easy for them, as well as personally satisfying. However, less than half of the participants felt that the quality of their teaching and their relationships with their students had improved since the adoption of online learning. Regarding the qualities of excellent online teachers, participants indicated that being respectful, enthusiastic about their teaching and their topics, striving to become a better teacher, being humble, and being knowledgeable about their subject matter were the top five qualities excellent online teachers should have. Comparison analysis indicated gender differences in some of the items. Women tended to feel more strongly that their relationship with their students had improved since online teaching was adopted; also, they gave higher scores to qualities such as being humble, establishing rapport, being sensitive and persistent, and being understanding compared to men. There were not differences based on age. Regarding online teaching training and work experiences, we found statistical differences in the perceptions on the quality of their teaching and some of the traits of excellent online educators. We found that participants with previous training and work experiences rated more strongly qualities such as being an effective communicator, being prepared and technologically competent. We discuss the implications of these findings considering the challenges that online learning imposes on educators in many parts of the world.
Frame-rate Up-conversion Detection Based on Convolutional Neural Network for Learning Spatiotemporal Features

With the advance in user-friendly and powerful video editing tools, anyone can easily manipulate videos without leaving prominent visual traces. Frame-rate up-conversion (FRUC), a representative temporal-domain operation, increases the motion continuity of videos with a lower frame-rate and is used by malicious counterfeiters in video tampering such as generating fake frame-rate video without improving the quality or mixing temporally spliced videos. FRUC is based on frame interpolation schemes and subtle artifacts that remain in interpolated frames are often difficult to distinguish. Hence, detecting such forgery traces is a critical issue in video forensics. This paper proposes a frame-rate conversion detection network (FCDNet) that learns forensic features caused by FRUC in an end-to-end fashion. The proposed network uses a stack of consecutive frames as the input and effectively learns interpolation artifacts using network blocks to learn spatiotemporal features. This study is the first attempt to apply a neural network to the detection of FRUC. Moreover, it can cover the following three types of frame interpolation schemes: nearest neighbor interpolation, bilinear interpolation, and motion-compensated interpolation. In contrast to existing methods that exploit all frames to verify integrity, the proposed approach achieves a high detection speed because it observes only six frames to test its authenticity. Extensive experiments were conducted with conventional forensic methods and neural networks for video forensic tasks to validate our research. The proposed network achieved state-of-the-art performance in terms of detecting the interpolated artifacts of FRUC. The experimental results also demonstrate that our trained model is robust for an unseen dataset, unlearned frame-rate, and unlearned quality factor.
Algorithm for Enhanced Columnar Transposition Technique

Cryptography is a field to solve the problems related to Information Security. There are numerous techniques like substitution and transposition methods to convert the real message into secret code which will be tough for intruder to understand .These techniques change the position or substitute intelligible message characters to produce the ciphertext which is more secure to transfer as compare to plaintext. Columnar Technique is also such technique which changes the position of plaintext message characters and produces the ciphertext. In this research paper, improved columnar technique is presented which will produce more randomness in the ciphertext generated to make it difficult for cryptanalyst to predict the plaintext from it. Keywords: Cryptography, Information Security, Rail Fence Technique, Transposition Techniques, Enhanced Algorithm
Big Data Analysis of Online Gender-Based Hate Speech: With a focus on comments on web portal news articles

Current studies on online gender-based hate speech have focused on legal regulations and countermeasures. In this study, we analyzed, using a data mining technique, comments on news articles about gender issues published on web portals. Our analysis of articles published by various newspaper companies on Naver and Daum revealed that hate speech in comments was significantly higher for articles reporting on specific events related to gender issues than for general articles on gender issues. This trend is consistent for articles across all news companies, regardless of political orientation. However, web portals have the power to regulate gender-based hate speech on their sites. Daum operates a reporting system for discrimination and hate speech and has significantly fewer hate speech postings compared to Naver, which lacks such a system. This study empirically analyzed the changes in the quantity of gender-based hate speech and found that web portals, commonly classified as bystanders or gatekeepers, can play a functional role in reducing online gender-based hate speech.

Pelatihan Membuat Sitasi Karya Ilmiah Mahasiswa Menggunakan Aplikasi Mendeley

Obstacles that often arise in the presentation of written and scientific works are not being careful in including quotations and finding it difficult to manage reference sources. If the references listed have enough sources, the citation must also be clear according to what he quoted from the original source. The purpose of writing citation sources and bibliography is so that we avoid plagiarism. One of the functions of quotations is to support or reinforce our writing. The method used in the implementation of this service is an intensive mentoring method with direct practice on the Mendeley desktop application. The results of the mentoring in the form of Mendeley training were obtained in the pre-test session, the test participants only got an average of 62.75. Meanwhile, after the assistance, the score increased significantly, the average score was 96.25. This shows that what they know in making references to scientific papers is still inadequate before the training is carried out. After the implementation of the training, it was seen that their knowledge increased significantly.

Pragmalinguistics Politeness in the Balinese Language

This study aims to determine the linguistic patterns of politeness in the Balinese language. The pragmalinguistic approach was used because the linguistic patterns and politeness of the Balinese language are related to descriptive and pragmatic aspects. Data were collected through closed questionnaires distributed to informants consisting of lecturers, teachers, and Balinese language practitioners. The respondents were asked to give a politeness score for each proposed sentence pattern using a Likert scale, where 1 = very impolite, 2 = impolite, 3 = polite, 4 = more polite, and 5 = very polite. The analysis results showed that (1) passive sentences (score 3.64 – 4.29) were perceived as more polite than active sentences (score 2.76 – 3.14), (2) modality phrase forwarding (score 4.00 – 4.79) were perceived as more polite than sentences without modalities (score 2.64 – 2.71), (3) the use of institutional personification (score 4.07 – 4.76) was perceived as more polite than using the position as the subject of the sentence (score 2.88 – 3.00), and (4) the use of indirect speech (score 4.14 – 4.79) was perceived as more polite than using direct (score 2.76 – 3.00). Furthermore, the use of these linguistic instruments to determine politeness in the Balinese language is motivated by the speaker's desire to focus on information, soften and weaken the impositivity, as well as efforts to save a positive face.
