This paper aims to discuss which basic implications firms need to be aware of if they decide to include equity shares as a part of salary payments in order for them to tackle financial risks due to the COVID-19 crisis, benefiting with better liquidity. We discuss this alternative from the strand of potential financial benefits, but also include a power perspective, emphasizing how firms could share with employees their decision-making processes as well as a part of their position of traditional hegemony. We concluded that firms’ decision regarding this financial alternative fits into a short-term benefit and at the same time threats a long run position of power.

Since 2015, the demand and price of lithium have increased considerably due to its central role in battery production. Latin America has around 60% of the world's lithium reserves. The deposits are mainly located in the Puna region shared by Chile, Bolivia, Peru and Argentina. The possibility of extracting lithium from salt flats is promoted by governments and companies as an undeniable opportunity. At the same time, lithium mining is presented as a key to solving the climate crisis, given the need to reduce greenhouse gases and favor the energy transition. In contrast, lithium extraction is considered by local communities as pernicious because the extraction involves the loss of large volumes of water, since lithium is dissolved in the salt flats and a large amount of fresh water is used during the process and because of the chemical contamination it generates. This paper will address t...

Geo-referenced textual data has been the subject of multiple investigations, by providing opportunities to better understand certain phenomena according to the content that is shared, either on-line such as social networks, blogs, and news; or through repositories such as scientific research articles, geo-referenced virtual books, among others. However, the characteristics of this information are studied, analyzed and processed separately, either through its textual components or its geo-spatial components, which offers a separate understanding of the results. In this paper, we propose an integration of textual and geo-spatial components from the pre-processing phase to the visualization stage, As a part of the Document Mapping process based on the phases of the Knowledge Discovery in Databases (KDD). Achieving two main results (1) minimize the problems that arise in the visual phase, su...

Technological advances have allowed to collect and store large volumes of data over the years. Besides, it is significant that today's applications have high performance and can analyze these large datasets effectively. Today, it remains a challenge for data mining to make its algorithms and applications equally efficient in the need of increasing data size and dimensionality [1]. To achieve this goal, many applications rely on parallelism, because it is an area that allows the reduction of cost depending on the execution time of the algorithms because it takes advantage of the characteristics of current computer architectures to run several processes concurrently [2]. This paper proposes a parallel version of the FuzzyPred algorithm based on the amount of data that can be processed within each of the processing threads, synchronously and independently.

In recent years, the giant squid processing industry in Peru exhibited a 59% increase in exports with respect to 2018. According to estimates, this industry generates approximately 30,900 jobs per year. However, some SMEs experience low productivity, such as the PECEPE company, due to plant downtime. This represents 26% of the available time, which translates into the loss of 1760 tons every year. The most constraining external factor the sector faces is uncertainty in resource availability caused by changing weather conditions and informal fishing activities. Although there is a large number of research studies on the fishing industry and resource extraction, literature on processing plant operations is scarce. Within this context, this study seeks to promote a high impact sector in Peru, as well as fostering processing plant competitiveness and productivity. Hence, to address these iss...
