Exploring the efficacy of writing comics as a tool for enhancing EFL writing skills of undergraduate Ecuadorian polytechnic students

Purpose This paper aims to identify the effectiveness, student perceptions and impacts of integrating comics into the English as a foreign language (EFL) writing curriculum for undergraduate Ecuadorian polytechnic students. Design/methodology/approach This research followed a mixed method design to obtain quantitative information through a researcher-made survey and paired T-test, which would be corroborated by the qualitative data obtained from semistructured interviews. Findings From the descriptive and T-test results and the interview answers, it is concluded that students have a favorable view of the effectiveness of using comics to improve their writing skills. They also expressed their engagement and motivation to work with comics. Research limitations/implications First, the research sample, comprised of 109 students, may restrict the generalizability of the findings beyond the specific context of this study. This constraint suggests caution in extrapolating these findings to broader student cohorts, emphasizing the need for larger-scale studies to validate the robustness and applicability of the outcomes. Second, the study’s focus solely on students from a polytechnic state university introduces a potential limitation concerning the diversity and representativeness of the participant pool. Consequently, the findings might be limited in their applicability and may not fully encompass students’ varied responses and attitudes from other educational backgrounds. Practical implications The scaffolding afforded by comics aligns with genre-based literacy perspectives, valuing instruction in textual genres and social purposes. From a practical pedagogical point of view, this paper’s results suggest the potential of comic narratives and storyboarding. Comics writing could be added to classroom activities to vibrantly aboard brainstorming, drafting and peer reviewing before dealing with higher-stakes assignments. Legitimizing alternative mediums like comics for academic writing tasks has social implications for promoting literacies in a multimedia world. Social implications Writing comics nurtures multiliteracies aligned with participatory digital cultures by expanding traditional linguistic-centric norms. This multimodal composing can potentially increase access and representation and amplify voices across identities and cultures. Originality/value Although the paper addresses a topic that is not entirely novel in research, its originality lies in its focus on data originating from Ecuador, where specific cultural nuances and educational contexts may influence the effectiveness of using comics to enhance EFL writing skills. Thus, it fills a gap in the existing literature on this subject.

Fandom and Fictionality after the Social Web: A Computational Study of AO3

Abstract: Web-based fanfiction is an increasingly important species of modern fiction that is necessary to understanding contemporary literary culture in a multimedia world. Using the Harry Potter fandom on the platform Archive of Our Own (AO3) as our case study, we combine close reading and computational analysis to examine the narrative features of fanfiction and the rhetorical commentary surrounding it. Our approach models a rapprochement between literary studies and fan studies, offering a new data-driven method for analyzing the relationship between traditionally published fiction, web-based fanfiction, and empirical forms of reader response.

Studentska vizija budućnosti školskoga predmeta povijest

History as a school subject has long struggled with a fundamental question – what is its role in education and what is its future. Historians are mostly focused on studying the past without regular analyzes of the state of subjects in schools. Debates on History in schools are left to the public and often to politicians. Since the establishment of independence in Croatia, three reforms of compulsory (primary) education have been implemented, which as a result did not bring a change in the teaching paradigm, but only added new content to the small teaching schedule. The paradigm shift has actually happened in information sources – the digital multimedia world is slowly taking over the central role of information sources from the hands of teachers, textbooks and other educational materials. In this research conducted on students of Croatian and Hungarian higher education institutions, we analyze the attitudes that shape the scenario of teaching history in 2031.

Digital Image Steganography Scheme for Speech Signals in the Discrete Wavelet Transform Domain

In recent years, the evolution and expansion of the multimedia world has allowed digital images to be widely used as a carrier medium for facilitating the sending and receiving of confidential digital content such as text, audio and images. However, there are few steganographic schemes that hide digital speech signals into digital images; also, the state-of-the-art methods have some disadvantages such as low embedding capacity, low quality in the modified image, and/or low audible quality in the recovered speech signal. In this paper, a new steganographic scheme that hides a digital speech signal into a color image is presented, where the embedding process is performed in the HL and LH channels of the first decomposition level of the discrete wavelet transform (DWT) over the YCbCr color space; additionally, a chaotic map method is implemented to encrypt the speech signal and to spread it throughout the whole image. Experimental results have demonstrated that the proposed scheme results in better performance against other state-of-the-art methods, due to their ability to embed and recover speech signals with duration up to 16.384 seconds using color images of 512×512 pixels, obtaining 32 dB and 0.92 in PSNR and SSIM, respectively for the stego-image, and 41 dB in SNR for the recovered speech signal.

Covert channel implementation using motion vectors over H.264 compression

Embedding information inside video streaming is a hot topic in the world of video broadcasting. Information assimilation can be used for positive purposes, such as copyright protection. On the other hand, it can be used for malicious purposes such as a hostile takeover, remotely, on end-user devices. The basic idea of information assimilation technology within a video is to take advantage of the sequence of frames that flows between the video server and the viewer. Casting foreigner data into each frame such a hidden communication channel is created namely - covert channel. Attackers find the multimedia world in general and video streaming, an attractive backdoor for cyber-attacks. Multimedia covert channels provide reasonable bandwidth and long-lasting transmission streams, suitable for planting malicious information and therefore used as an exploit alternative. In this article, we propose a method to protect against attacks that use video payload for transferring confidential data using a covert channel. This work is part of a large-scale study of video attack methods. The goal of the study is to build a generic platform that will investigate the reliability of video sequences. The platform allows to encoding and decoding video. A plugin can be added to each encoder or decoder. Each plugin is an algorithm that is studied and developed in the framework of this study. One of the algorithms in this platform is information transmission over video using motion vectors. This method is the topic off this article.

GP based smart reversible watermarking of depth image based rendering for stereoscopic images

Depth Image Based Rendering (DIBR) for 3D-TV, or free-view TV, is one of the most promising techniques in multimedia world, whereby a monoscopic image and the depth image of the same view are utilized to generate stereoscopic left and right images. Therefore, the protection of valuable content generated for 3D TV is an important concern in the world of digital media. In this paper, we exploit an interpolation errors expansion scheme by employing Genetic Programming based smart reversible watermarking technique that is viable for 3D-TV. The proposed technique exploits directional weights using hidden dependencies pertaining to the imperceptibility and capacity of the watermark in a previously established interpolation scheme. It then embeds the watermark in the 3D content using interpolation error expansion based reversible watermarking scheme. Previously presented empirical techniques are not much effective as they use hit and trial strategies for selecting optimal weights for watermark embedding. The proposed technique achieves significant watermark capacity as well as imperceptibility, and is reversible when compared to existing state of the art techniques.

JPEG-1 standard 25 years: past, present, and future reasons for a success

Digital image capture, processing, storage, transmission, and display are now taken for granted as part of the technology of modern everyday life. Digital image compression is one of the enabling technologies of the present multimedia world. The image compression technique used for application as diverse as photography, web pages, medical imaging, and public records is JPEG, named after the ISO/CCITT “joint photographic experts group,” established in 1986, which developed the technique in the late 1980s and produced the international standard in the early ’90s. ITU-T T.81¦ISO/IEC 10918-1, also called “JPEG-1” has become one of the most successful standards in information and communication technologies (ICT) history. The authors of this paper—all members of the original JPEG development team—were all intimately involved in image-coding research and JPEG in particular. The paper goes behind the scenes explaining why and how JPEG came about and looks under the bonnet of the technique explaining the different components that give the standard of its efficiency, versatility, and robustness that have made a technique that has stood the test of time and evolved to cover applications beyond its original scope. In addition, the authors give a short outlook of the main milestones in coding schemes of still images since “JPEG-1.”

SHIFT FROM “ME” TO “WE” IN SOCIAL MEDIA

Currently media power is distributed via the multi-media World Wide Web. Web 2.0 has transformed every prosumer into an individual, mini-organism – “Me the Media” (the concept coined by Bloem, van Doorn & Duivestein 2009). Recently a trend has started to emerge, which indicates that Web conversations are creating new power relationships. This is especially vivid in the current multi-media coverage of political events, supported by cross-cultural social activism. Thus, the aim of this study is to analyse the emerging new trends in current social media that embody the shift from “Me” to “We” in power relationships. The idea that everyone is inter-linked and inter-active on the Web, involving not only common citizens and politicians, but also companies or brands, supports the finding that “We the Media” is the next development in social media, which needs to be taken seriously and investigated on a wider scale.

Adaptive Histogram Equalization Based Image Forensics Using Statistics of DC DCT Coefficients

The vulnerability of digital images is growing towards manipulation. This motivated an area of research to deal with digital image forgeries. The certifying origin and content of digital images is an open problem in the multimedia world. One of the ways to find the truth of images is finding the presence of any type of contrast enhancement. In this work, novel and simple machine learning tool is proposed to detect the presence of histogram equalization using statistical parameters of DC Discrete Cosine Transform (DCT) coefficients. The statistical parameters of the Gaussian Mixture Model (GMM) fitted to DC DCT coefficients are used as features for classifying original and histogram equalized images. An SVM classifier has been developed to classify original and histogram equalized image which can detect histogram equalized image with accuracy greater than 95% when false rate is less than 5%.

Techniques to Detect Modified Video

In today’s multimedia world, billions of photographs and videos are generated each day. Of these, about 30,000 are obtained by the U.S. government for law enforcement and intelligence purposes. These could be photos and videos of people, including child pornography, that are of interest to the FBI, videos from surveillance cameras, or photos and videos obtained from foreign adversaries that may be a threat to the United States. Material may also be multimedia submitted to news services or posted to the internet that portray world events that could affect decisions made by our leadership. Of these images or videos, some could have been altered to improve the artistic appearance or storytelling aspects of the material, but some of the alterations may have been done to change the narrative to influence events, spread false information, or provide misdirection. Defense Advanced Research Projects Agency (DARPA) has begun a multiyear program to automate the detection of modified videos and images called Media Forensics (MEDIFOR). The details of this program are beyond the scope of this paper, but the program is referenced to illustrate the seriousness of this problem. This paper will describe some of the tests that have been done manually through the years to identify falsified material without the aid of the technology that is now being developed for the MEDIFOR program. <disp-quote xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> This paper will describe some of the tests that have been done manually through the years to identify falsified material without the aid of the technology that is now being developed for the MEDIFOR program. </disp-quote>

Survey of Transportation of Adaptive Multimedia Streaming service in Internet

World Wide Web is the greatest boon towards the technological advancement of modern era. Using the benefits of Internet globally, anywhere and anytime, users can avail the benefits of accessing live and on demand video services. The streaming media systems such as YouTube, Netflix, and Apple Music are reining the multimedia world with frequent popularity among users. A key concern of quality perceived for video streaming applications over Internet is the Quality of Experience (QoE) that users go through. Due to changing network conditions, bit rate and initial delay and the multimedia file freezes or provide poor video quality to the end users, researchers across industry and academia are explored HTTP Adaptive Streaming (HAS), which split the video content into multiple segments and offer the clients at varying qualities. The video player at the client side plays a vital role in buffer management and choosing the appropriate bit rate for each such segment of video to be transmitted. A higher bit rate transmitted video pauses in between whereas, a lower bit rate video lacks in quality, requiring a tradeoff between them. The need of the hour was to adaptively varying the bit rate and video quality to match the transmission media conditions. Further, The main aim of this paper is to give an overview on the state of the art HAS techniques across multimedia and networking domains. A detailed survey was conducted to analyze challenges and solutions in adaptive streaming algorithms, QoE, network protocols, buffering and etc. It also focuses on various challenges on QoE influence factors in a fluctuating network condition, which are often ignored in present HAS methodologies. Furthermore, this survey will enable network and multimedia researchers a fair amount of understanding about the latest happenings of adaptive streaming and the necessary improvements that can be incorporated in future developments.

New communication practices on the radio and in the audiosphere

For the past decade or so, internet radio, podcasts, mobile sound apps, and digital libraries of audio content have enjoyed increasing popularity among researchers and receivers of culture. Radio, similarly to other traditional media, often experiments with the opportunities offered by the new media technologies enabling the emergence of new communicational practices. As a starting point, I consider the contemporary audiosphere, which constitutes the auditory part of the audio-visual culture, and the influence of technological changes on radio communications, artists, and receivers. I attempt to answer the question, what happens at genre fringes? What are the characteristic features of the emerging forms? How, when one is faced with new technology, the multimedia world, and virtual reality, can one reach a reflection on the fiction and non-fiction genres on the radio? The expansive character of new technologies is often the source of inspiration for that which is traditional, thus renewing the object of its study. The inclusion of new phenomena within the widely understood auditoriness has a rescuing nature for traditional forms, and, at the same time, offers new opportunities for creators, and thus an area of research for literary scientists, media scientists and literary critics.

Challenges in the Integration of Multimedia by History Teachers in the North West Province of South Africa

ABSTRACTToday’s learners are born into a multimedia world and feel quite comfortable in an electronic learning environment. The high-quality sound, realistic colour images, graphics, narrations, real-time recordings and full motion videos from multimedia, which are integrated in History lessons, are what the learners of today want and need in their learning. In the study on which this article is based, efforts were made to determine the extent to which Intermediate Phase History teachers (Grade 4-6) of schools in the townships and rural areas in and around the Klerksdorp, Rustenburg and Vryburg districts of the North West Province of South Africa were willing to utilise multimedia in their History (Social Science) lessons. The challenges these History teachers experienced when they were faced with the application of multimedia in their lessons are also highlighted. In the last part of the article recommendations are made to serve as future suggestions for History teachers to apply multimedia in the teaching of the subject.

Teaching Anatomy in the Multimedia World—Using Digital Tools for Progressive Learning over Time

In a cross-faculty project journalism students filmed anatomy briefings on a medical program. The material gave medical students free access to rehearse and repeat over time. The journalism students on their part practiced camera technique, directing and editing: It was an opportunity for students to help students. Following a quality evaluation of undergraduate studies at the Lund University medical faculty in 2011, we explored, developed, and implemented novel educational tools to meet students’ need in the multimedia world in which they operate. Incorporating complementary digital learning resources, in particular integration with mobile applications enabled us to meet students in their own world, thereby enhancing the learning process. We produced short video clips on specific anatomic themes, following the curriculum of the well-established anatomy course, and posted them online, allowing continuous rehearsal and repetition over time at a pace that suits individual students. Also, available to all semesters it provides free opportunities for repetition, reducing the risk of knowledge-loss between basic and clinical parts of the program. Besides the obvious benefits for students, the material gave teachers a clear view of the students’ curriculum. Thus, the material can be used for alternative, more interactive forms of examination. The paper describes the project, and the results from evaluations and integration with mobile technology.

Image data security is the essential portion in communication and multi media world. During storing and sharing, avoid third party access of data is the challenge one. Providing security of data is the clever work and art also. Many protection algorithms are used in recent years. Protection may be given of a data is converting the original in to some unknown form, signals, sketch etc., which is not understand by any one. Cryptography is the best technique of image data security. In Greek, crypto refers hidden and graphy refers script. Cryptography has two processes namely encryption and decryption. Encryption achieves the conversion by possessing a key of original data into unreadable form called encoding. Restoring of encrypted data in to original is decoding or decryption. Key, code or password is the vital role in cryptography. This paper presents the performance of encryption and decryption of an image using a single key algorithm and tested on some images and shows fine results.
