The Influence of Institutional Voids in the Institutionalization of Bitcoins as a Currency

Bitcoin is a social movement, which promises free and decentralized money, absent from the traditional regulatory institutions, but it can be challenging for financial industry regulators and other players in the financial markets. Thus, our study aims to analyze how the institutional voids manifest in the bitcoin institutionalization process as a currency. We adopt the institutional theory, from the perspective of institutional voids, in order to observe the concepts in emerging markets that show the difficulty or the beginning of the institutionalization of bitcoin as a currency. The institutional theory provides an opportunity to understand the reasons for using particular practices, actions, or manifestations. Our method is based on a qualitative exploratory approach with semi-structured interviews to understand how financial market experts perceive this phenomenon. Our results show that it is possible to identify how institutional voids manifest themselves, reinforcing the debate on whether bitcoin is, in fact, a currency.
LSB based Digital Image Steganography System

Steganography can be defined as inserting information, such as a text file or a picture file into different types of files such as a picture file, audio file, or a video file.Digital picture steganography is a branch of computer science that is interested in inserting textual/pictorial confidential messages into digital pictures.The purpose of digital picture steganography is securing private and sensitive textual/pictorial information by inserting it into a shield digital picture.Nowadays, digital picture steganography has become an important topic since there is a need for securing digital information.In this paper, a digital picture steganography system is proposed.The proposed system is implemented as a desktop application.The system consists of two parts: confidential picture hiding and confidential picture extraction.To hide a confidential picture into a shield picture, both pictures are shuffled using Arnold Transform.Then, the confidential picture is encrypted and embedded into the shield picture using LSB technique.After that, the stego picture is de-shuffled using Arnold Inverse Transform.To take out a confidential picture from a stego picture, a stego picture is shuffled using Arnold Transform.Then the confidential picture is taken out from the LBS of stego picture.After that, the confidential picture is decrypted and de-shuffled using Arnold Inverse Transform.To evaluate the performance of the system, it was experimented in different gray scale images and PSNR and MSE were calculated and compared.
The area~ System: Exploring Real and Virtual Environments Through Gestural Ambisonics and Audio Augmented Reality

In this paper, I outline the development and evaluation of the area~ system.area~ enables users to record, manipulate, and spatialise virtual audio samples or nodes around their immediate environment.Through a combination of ambisonics audio rendering and hand gesture tracking, this system calls attention to the ability of non-visual augmented reality (AR), here, audio augmented reality (AAR), to provide new aesthetic experiences of real and virtual environments.The system is contextualised within the move in computational art, and indeed, broader human computer interaction research, towards multisensory interaction.In particular, area~ is situated in the creative practice of works using multisensory AR as a medium to create expressive computational art. Through an autobiographical design study, these experiences are discussed in relation to the research question: "How can we better understand relationships between virtual and real environments through gesture and virtually placed audio augmented reality objects?" This hypothesis studyproposes that new aesthetic experiences can result from the system and are waiting to be tested through user studies.The adoption of the Project North Star open-source AR head-mounted-display (HMD) could expand the possibilities of the area~ system by reducing the need to be tethered to a laptop and table for hand gesture input.In discussing the future development of the system and my research, I propose a devising practice-led method for creating and evaluating new multisensory AR (MSAR) Experiences; as well as the tantalising prospect of adding interaction between other sensory modalities to the area~ system, such as vision or smell, which would be made possible by the use of this open-source HMD.
Automatic Generation of ROP Through Static Instructions Assignment and Dynamic Memory Analysis

W⊕X is a protection mechanism against control-flow hijacking attacks. Return-oriented programming (ROP) can perform a specific function by searching for appropriate assembly instruction fragments (gadgets) in a code segment and bypass the W⊕X. However, manual search for gadgets that match the conditions is inefficient, with high error and missing rates. In order to improve the efficiency of ROP generation, the authors propose an automatic generation method based on a fragmented layout called automatic generation of ROP. This method designs new intermediate instruction construction rules based on an automatic ROP generation framework Q, uses symbolic execution to analyze program memory states and construct data constraints for multi-modules ROP, and solves ROP data constraints to generate test cases of an ROP chain. Experiments show that this method can effectively improve the space efficiency of the ROP chain and lower the requirements of the ROP layout on memory conditions.
Performance comparison between naive bayes and k- nearest neighbor algorithm for the classification of Indonesian language articles

&lt;span id="docs-internal-guid-210930a7-7fff-b7fb-428b-3176d3549972"&gt;&lt;span&gt;The match between the contents of the article and the article theme is the main factor whether or not an article is accepted. Many people are still confused to determine the theme of the article appropriate to the article they have. For that reason, we need a document classification algorithm that can group the articles automatically and accurately. Many classification algorithms can be used. The algorithm used in this study is naive bayes and the k-nearest neighbor algorithm is used as the baseline. The naive bayes algorithm was chosen because it can produce maximum accuracy with little training data. While the k-nearest neighbor algorithm was chosen because the algorithm is robust against data noise. The performance of the two algorithms will be compared, so it can be seen which algorithm is better in classifying documents. The comes about obtained show that the naive bayes algorithm has way better execution with an accuracy rate of 88%, while the k-nearest neighbor algorithm has a fairly low accuracy rate of 60%.&lt;/span&gt;&lt;/span&gt;
Struggles of Tamang children in achieving elementary education

This paper explores on how Tamang children achieve elementary education along with their socioeconomic conditions. This study tries to assess the impact of living condition, home and surrounding environment, parental education, and economic condition of the family on elementary education of Tamang children of Dhankuta district, aged 6-14 of. Data were collected from 15 households, purposively selected, through interview and observation, and the thematic analysis was done employing qualitative research design. It was found that, of the total 18 children,27.27% were non-enrolled, 24.14% drop-outs while 48.56% were continuing formal education. It was also found that the economic factors (poverty), family size, and home condition were the major struggle of the Tamang children in achieving elementary education. To combat with these issues income generation and poverty alleviation programs should be properly implemented; more job opportunities and shelters for the shelterless families are to be provided at low and affordable prices; and teachers and school authorities should make the parents aware about the importance of sending children regularly to school.

Déjà vu: Abusing Browser Cache Headers to Identify and Track Online Users

Abstract Many browser cache attacks have been proposed in the literature to sniff the user’s browsing history. All of them rely on specific time measurements to infer if a resource is in the cache or not. Unlike the state-of-the-art, this paper reports on a novel cache-based attack that is not a timing attack but that abuses the HTTP cache-control and expires headers to extract the exact date and time when a resource was cached by the browser. The privacy implications are serious as this information can not only be utilized to detect if a website was visited by the user but it can also help build a timeline of the user’s visits. This goes beyond traditional history sniffing attacks as we can observe patterns of visit and model user’s behavior on the web. To evaluate the impact of our attack, we tested it on all major browsers and found that all of them, except the ones based on WebKit, are vulnerable to it. Since our attack requires specific HTTP headers to be present, we also crawled the T ranco Top 100K websites and identified 12, 970 of them can be detected with our approach. Among them, 1, 910 deliver resources that have expiry dates greater than 100 days, enabling long-term user tracking. Finally, we discuss possible defenses at both the browser and standard levels to prevent users from being tracked.
PENGEMBANGAN MEDIA VIRTUAL BOOK PADA MATERI BENTUK MOLEKUL

Research on the development of virtual books on geometri molecular form materials at MAS Ulumuddin Lhokseumawe, was motivated by the limited use of instructional media in learning process. The learning media used are reading books and LKPD, chemistry learning is also often considered difficult because generally the geometry molecular material is abstract and requires high imagination to understand it. Virtual books are media with animation in the form of software that can be accessed or opened via computers and laptops. The media is equipped with covers, instructions user, concept maps, materials, 3D molecular shapes and quizzes. The purpose of this study was to determine the development of a virtual book on molecular form materials using the development research method using the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). Data collection techniques are validation sheets and response questionnaires. Based on the results of validation I 83.2%, validator II 92.8% and validator III 89.6%, the average score of expert validators from the expert validation sheet is 88.53% with very good criteria of virtual book.

ANALYSIS OF WRITING MATERIALS AND ACTIVITIES IN “ WHEN ENGLISH RINGS A BELL” IN TEXTBOOK

Abstract. A Textbook is a reference for teachers and students on learning. (Awasthi, 2006) Says textbooks are learning material for both teachers and students in the learning and teaching process, especially in students for learning activities. This study aims to analyze the material and student activity in textbooks. The analysis is focused on the presentation of the materials and assignments written by the students. This research is descriptive qualitative using content analysis. From the aspect of presenting writing material and activities, all writing materials and assignments are in the form of a guide. writing, because students are asked to write responses, in limited length, to the instructions given. This study shows that writing assignments in textbooks are proportionately covered. The findings suggest that independent references to vocabulary and grammar are required for independent study. With written assignment activities presented in the textbook material, students understand better the previous lesson and are more active in the learning process. The topics presented are diverse so that students have the opportunity to explain the topic in different ways.
