  • REMOTE LEARNING UNDER THE COVID-19 SOCIAL DISTANCING: REFLECTIONS AND A NETNOGRAPHY STUDY Article

    Nasu, Vitor Hideo

    Abstract in English:

    ABSTRACT The purpose of this work is two-fold. First, it intends to discuss and reflect on the transition from face-to-face to remote learning in accounting education because of the COVID-19 pandemic. And second, it presents the results of a netnography study conducted at the beginning of the COVID-19 outbreak in Brazil (March and April of 2020). I also provide some personal experiences during these times. In section 2, I provide key technology resources I found helpful for accounting instructors and students. In section 3, I discuss the implications for instructors and students brought by the COVID-19. I especially appreciate the effors that both instructors and students are doing to keep their academic lives going, despite all the adversity. In section 4, I describe a netnography study in which I examined data from a Facebook community of graduate students.. And in section 5, I report closing thoughts.
  • AN ICT-BASED EXTENSION SERVICES’ ADOPTION MODEL FOR PUBLIC EXTENSION OFFICERS: A CASE IN MALI Article

    Kante, Macire

    Abstract in English:

    Abstract The realization of higher yield and therefore agricultural productivity cannot be achieved without information. That information is disseminated in developing countries, particularly Mali by government-led extension services. However, there are few (public) extension officers to disseminate that information. That makes the use of other means such as ICT one of the best ways to disseminate the extension services. This paper, firstly, looked at the drivers and challenges of the adoption of ICT based extension services by public extension officers in Mali from the literature to propose a conceptual framework. Secondly, the study assessed the survey questionnaire and thirdly, evaluated the proposed model. A sequential exploratory research design was followed. It consisted of conducting in-depth-interviews with 12 key stakeholders (agricultural scientist, policymakers, IT professional and head of extension services) in Bamako and Koulikoro. These data were analysed using computer-assisted qualitative data analysis software (RQDA) to contextualize the proposed conceptual framework. Thereafter, a survey questionnaire was designed and administered to 21 public extension officers in Bamako, Kati and Koulikoro. Quantitative data was analysed using Partial Least Square Structural Equation Modelling with the aid of the software Smartpls 3.2.8. This study validated a questionnaire of 19 items out of 26 for the next phase of the study with more respondents. Additionally, the results revealed that Relative Advantage, High Cost, Compatibility, Complexity, ICT-Skills and Policy explained 48.4% of the variance of the adoption of ICT based extension services by public extension officers.
  • SOCIAL MEDIA/NETWORKING: APPLICATIONS, TECHNOLOGIES, THEORIES Artigo

    Madakam, Somayya; Tripathi, Siddharth

    Abstract in English:

    ABSTRACT Nowadays, Social Media communication has become indispensable for the world. Social Media is indeed a paradigm shift in communication. The beauty of this new communication method is the offer of virtual connectivity irrespective of geographical distances. The medium serves us pictures, rich textual content, videos, and audio 24/7 online. Given its wide usage, it is highly crucial to study key details of social media, including the pioneers, theories, and business applications. This manuscript has relied on the “Web of Science” database and the Vantage Point 9 text-mining tool, with Aduna map visualization, to collate about 50 research articles published during 2008-2016 that have studied social media in detail. The objective of this article is to explain the impact of social media sites, technologies, and applications.
  • A DYNAMIC JOB SHOP MODEL FOR SCHEDULING TASKS IN A SOFTWARE DEVELOPMENT ENVIRONMENT Original Article

    Ribeiro, Sildenir A.; Schmitz, Eber A.; Silva, Mônica F. da; de Alencar, Antônio Juarez S. M.

    Abstract in English:

    ABSTRACT This work proposes a Dynamic Job Shop Scheduling (DJSS) model for scheduling the task in a software production environment. The aim is to organize the insertion of tasks in the shop in a precedence order previously defined that obeys the mapping of the critical path and the critical chain to identify constraints in the productive process. The complexity and dynamism of the software development environment require a mature and adjusted process that enables management throughout its extension. Therefore, the Unified Process (UP) was used in conjunction with the Theory of Constraints (TOC) in the Software Development Process (SDP). The UP requires an efficient model for the processing of activities, given by the set of independent variables involved in the process. For this reason, a model to programming the task based on dynamic scheduling was developed. The problem around the DJSS is to program the tasks in the shop in a way that allows identifying one or more production lines in the shop with constraints of capacity at runtime. A capacity constraint is any element that disturbs the productive process, causing L={Mi Aj} to have delivery (DA) of less than 100% of the artifacts, given by the set of jobs (jn) scheduled. The resource with capacity constraint limits the production of the machines in the production line, leading to bottlenecks in the production process. A bottleneck, in turn, is denoted by the production limitation of a machine (people) caused by one or more capacity constraints that imply maximum production, which in this case is defined by D={Mi, Aj=100%}. In this work, the maximum production is given by the set of tasks processed in each of the phases of the UP and according to the productive calendar, which delimits the deadline of each delivery and establishes the budget of hours for the shop. The set of tasks scheduled and "rescheduling" and properly processed in all phases define the total production of each machine. The use of DJSS facilitated the organization and management of insertion and rescheduling operations in the shop and as result, produced data to measure the effort/time that allowed identifying the bottleneck of the software production process.
  • E-Learning Management Systems: A Feature-based Comparative Analysis Original Article

    Salah, Saeed; Thabet, Mahmoud

    Abstract in English:

    ABSTRACT One of the main important resources for higher education is a Learning Management System (LMS), which has shown an enhancement of students’ progress with high quality learning outcomes worldwide. Many e-learning tools exist, each one has its own weaknesses and strongest points to the online learning process. This number increases continuously, and the existing tools are being updated, redeveloped, and upgraded. The aim of this study is to present a comprehensive comparative analysis between existing e-learning management systems. Unlike other relevant studies that have narrow scope either in terms of the number of tools or the number of comparative features, this work considers top twenty, highly recommended tools, both open source and commercial. Furthermore, more than twenty evaluation features were used carefully to fulfil students’ and instructors’ current needs. The results of this study have shown that Moodle outperforms the others and it is considered as the best free open source tool for educational purposes. It supports more than 100 different languages and provides its services to more than tens of millions of customers worldwide. Besides to Moodle, Chamilo, TotaraLearn, Open edX and Sakai have more built-in features that provide services to educational institutions. Also, this study showed that Docebo, SkyPrep, ProProfs, SAP Litmos, Moodle, TotaraLearn, Open edX and Opigno systems have more built-in security mechanisms such as antispam, antivirus, IP Blocker, data protection and complex password enforcement. Most considered systems have gamification features except Schoology, ATutor, Sakai, and Ilias, and most commercial systems can offer 24/7 customer care services, except Edmodo and Telnet, whereas open source tools offer this service on specific time slots except Opigno, Ilias, TotaraLearn, Chamilo, and Canvas where the service is offered 24/7.
