- ArtículoAcceso AbiertoCOVID-19, Changes in Educational Practices and the Perception of Stress by University Educators in Latin America – a Post-pandemic Analysis(2023)The COVID-19 pandemic brought about profound changes in social and professional contexts. Schools and universities all over the world were closed to curb the contamination. In a short period, many educators were forced to reinvent their classes in a non-classroom mode, mediated by technology. This scenario of overwork can lead educators to stress, favoring distress, anxiety, and depression due to the uncertainties resulting from the pandemic and the search for new knowledge acquisition. This paper shows the research results conducted by university educators in Latin America who have been exercising teaching activities during social isolation imposed by COVID-19. The results show that with just one exception, educators from all countries reported suffering from some stress-related aspects concerning some manner to remote teaching. Higher workload perception came from women, unfolding gender inequalities amplified during pandemics. There is no clear relationship between the degree of technological expertise and stress factors, although, in general, educators use more time to prepare learning material and monitor students’ progress. Technological infrastructure was not a big concern for those educators in big cities, but some fundamental infrastructure problems were reported due to each country’s economic reality or geographic conditions.
- Documento de conferenciaAcceso AbiertoBootstrapping safe IVIS development with an affordable testing suite(2022)In-vehicle information systems (IVIS) represent a growing industry. IVIS were originally built and deployed by car manufacturers, which ensured that they complied with the safety regulations of the car industry. Nowadays, IVIS enter the vehicle in the driver’s and passenger’s phones. These “nomadic IVIS”, which sometimes interact with the car’s entertainment system, can escape important safety checks. Any software developer, without training in vehicle safety, can build and distribute IVIS. This reality calls for tools and methods that help software developers conceive safe applications. This article proposes an affordable and reliable testing suite that provides support to developers of nomadic IVIS. The suite takes the form of a simulation and data collection environment, oriented to the rapid prototyping of IVIS. It considers security requirements while maintaining a low technological and economic threshold, to provide easy access to developers compared to expensive physical environments with real vehicles.
- ArtículoAcceso AbiertoDesign thinking and compliance as drivers for decision support system adoption in agriculture(2023)To respond to increasing demands for good agricultural practices (GAP) and food safety, governments globally are introducing stringent regulations to govern agricultural compliance that affect production, storage, and sales activities. New legislation in Argentina to enforce GAP is an opportunity to test compliance as an incentive to adopt technological solutions. This research aims to determine whether compliance software is an effective gateway to shift farmers’ decision-making strategies from intuition-based to evidence-based, improving agricultural productivity through technology. Integrating technology can be a significant hurdle for farms but is also a steppingstone towards more reliable processes. To address this, the authors prototype a decision support system (DSS) for greenhouse farmers in La Plata, Argentina, to help farmers keep traceable records of their crops and treatments to reduce compliance risk. The project incorporates lessons learned from previous DSS projects and utilises design-thinking strategies to involve the end-user in the development.
- Documento de conferenciaAcceso AbiertoA collaborative approach to specify Kernel sentences using natural language(2022)Requirements engineering is a critical part of software development. Errors in the requirements, if not found and corrected early in the engineering process, become costly problems later on. Analysts commonly rely on Use Cases or Users Stories to capture requirements. However, there is domain knowledge that these artifacts don’t capture well (for example, business rules and given-then-when scenarios). Such domain knowledge is generally distributed among multiple stakeholders and domain experts with complementing perspectives. Therefore, it is important to use a collaborative technique with a simple artifact to acquire and validate their knowledge. Kernel sentences is a linguistic definition about small sentences (with only one verb) written in active voice. Some authors relate kernel sentences to business rules. We argue that kernel sentences are adequate to use in the collaborative acquisition and they can be used as the input to produce more complex artifacts. This paper proposes a collaborative approach to acquire and validate kernel sentences. The process has three main activities: acquisition of the kernel sentences, validation of them, and assessment of the activity of the experts who participate in the activity. This paper also describes a prototype to support the process. Finally, the paper shows the result of a preliminary evaluation with promising results about the applicability of the process.
- Documento de conferenciaAcceso AbiertoAn iterative and collaborative approach to specify scenarios using natural language(2022)Requirements engineering is one of the most important stages in software development. Errors committed at this stage require a lot of effort to fix in further stages. There are two main strategies to deal with software development: classic and agile. Classic software development relies on an extensive and very detailed specification, while agile development minimizes the effort on requirements specifications, relying on brief descriptions and a running prototype as a means of communication. Before the specification of requirements, there are some preliminary meetings held between the stakeholders and the IT team with the objective of discovering the goal and scope of the application to be developed. The knowledge transferred during these meetings is crucial to provide a context to requirements, no matters whether the approach is classic or agile. We argue that scenarios written in natural language are adequate artifacts to capture this knowledge. This paper proposes an iterative and collaborative approach to describe scenarios. The approach has two main activities: one of them is concerned with the description that stakeholders should perform, while the other provides guidelines to verify and possible improve the scenarios. This paper also presents a prototype tool that helps enforcing these guidelines automatically. This prototype relies on natural language processing. Finally, the paper shows the result of a preliminary evaluation of the proposed approach that indicates its results are promising.
