Binge-watching refers to watching more than two episodes of a television show in a single sitting. This pattern of behavior can be seen in people of a wide range of ages, but it is particularly widespread among people of millennial age and younger. In this study, we propose a model that explains binge-watching engagement by theorizing and testing the association of social influence on perceived usefulness, regret on the continuous intention of binge-watching, and habit on continuous intention and binge-watching engagement. The authors evaluated the model using data collected from 225 respondents. The results supported the proposed hypotheses and confirmed that regret does not neutralize the positiveand strongeffect of perceived usefulness and habit on binge-watching.

Researchers and organizations are beginning to recognize the potential benefits of this technology and are exploring how it can disrupt our world. However, the reality is that there has not been much progress in getting blockchain from a concept to widespread adoption. This study aimed to investigate the factors that influence the adoption of blockchain technology. We proposed a model that incorporated relevant features to blockchain technology adoption, specifically the role of Trust and Security as mediating variables. Data was collected using a questionnaire administered to people working in companies independently of their technology usage. Structural equation modeling using partial least squares (SEM-PLS) was used to analyze the data and construct the model. Results indicated that performance expectancy, social influence, and trust positively influenced people's actual use or intention to adopt blockchain technology. Additionally, environmental concerns had a negative effect on the intention to adopt. These findings suggest that individuals are more likely to adopt blockchain technology when they perceive it as valuable and trustworthy and receive support from their social networks.

Internationalization refers to the process of reengineering a system such that it could support various languages and regions without further modification. Localization refers to the process of adapting an internationalized software for a specific language or region. Due to various reasons, many large legacy systems did not consider internationalization and localization at the early stage of development. In this paper, we present our experience on, and propose a process along with tool supports for software internationalization and localization. We reengineer a large legacy commercial financial system called PAM of State Street Corporation, which is written in C/C++, containing 30 different modules, and more than 5 millions of lines of source code. We propose a source code ranker that recovers important source code to be analyzed. Based on this code, we extract general patterns of the source code that need to be reengineered for internationalization. We divide the patterns into 2 categories: convertible patterns and suspicious patterns. To locate the source code that need to be modified, we develop an automated tool I18nLocator, that consumes these patterns and outputs the locations that match the patterns. The source codes matching the convertible patterns are automatically converted, and those matching the suspicious patterns are converted by developers considering the context of the corresponding codes. For localization, we extract hard-coded strings, translate them, and store them into resource data files. Out of the 504 thousands of lines of source code that are modified using our proposed approach, we can automatically modify 79.76% of them, saving much valuable developers' time. The quality of the resultant system is also good. The number of bugs per lines of code modified found during user acceptance test and deployment to the production environment is 0.000218 bugs/LOC.

A utilização destes sistemas em contexto de ensino da gestão constitui uma oportunidade que as instituições de ensino têm vindo a aproveitar, de forma a melhorar os seus indicies de performance empregabilidade, satisfação e a aproximarem-se das necessidades do mercado. Este artigo avalia se a adoção e utilização de um software de ERP num contexto de ensino, traz melhorias na aprendizagem e sedimentação de conhecimentos de gestão e mais próximo dos requisitos de mercado. De forma a realizar esta avaliação, foi inicialmente elaborado um plano curricular capaz fornecer aos alunos a aprendizagem de conceitos teóricos sobre sistemas empresariais e de proporcionar a interação com um ERP real. De seguida com o intuito de avaliar o sucesso da integração do ERP no plano curricular foi desenvolvido um estudo com métodos qualitativos para averiguar o entendimento dos alunos quanto a conhecimentos chave sobre os ERP e da gestão em geral.

This becomes an issue when abinitio pilots start to use Electronic Flight Bags (EFB) without any proper training during flight school. Some EFB are available to pilots on digital stores who can buy and install this software. Some available products are among others Foreflight, Garmin pilot and Skydemon often used for visual or instrument navigations. The use of these devices in aircrafts with analog instruments can divert the pilot attention from flying the aircraft, to being focused on changing settings with a head-down attitude, losing situational awareness from the remaining flight instruments. This article makes a review of the current body of literature in this area and analyses the accident data of one of the most important databases in accident investigation in aviation. Some findings point to the key insights affecting Situational Awareness and human-machine interaction on pilots using EFB.

communication on Twier and understand the sentiment of their communication. First by identifying their communication performance
regarding the daily number of tweets, favourite tweets, number of retweets per day and per political party. We present a sentiment
analysis by the political party using tweets data. In this study, we propose an explanatory model with the main drivers of retweets. To
conduct this study, our approach used data analysis and machine learning techniques methods. Results indicate the main determinants
that influence future retweets of political posts globally. Here we present a comparison of the communication content between tweets
posts and the political parties’ programs available on their institutional websites. We identify the similarities between tweets and formal
programs per party and among all parties. Globally contribute to analyze the coherence and effectiveness of the political parties’
communication.
embody decisions that maybe incorporate in a decision tree. This decision tree may be helpful in the choice of adequate data visualization form managerial dashboards. For future works, we suggest conducting an empirical work that uses this decision tree to understand the impacts on its usage on management context better.
