Investment in productive and financial assets are a decision made as an alternative to direct resources to bring greater value and higher performance to an economic entity. The objective of this article is to analyze the return risk of the stocks of two companies listed on the Mexican Stock Exchange (BMV), presenting the case of the companies Grupo Bimbo, SAB de CV, and GRUMA, SAB de CV, both companies listed on the Mexican Stock Exchange, belonging to the industrial sector specifically the food and beverage sub-sector, being the most representative companies of this sector. The return on the portfolio is 0.27256% and the risk is 0.0121862, with an investment of 50% in each of them. The period analyzed was from 2015 to 2018. It is important to base decision-making by considering the risk analysis and performance of financial assets in where you wish to invest, in addition to relying on other analyzes such as fundamental and technical analysis, among others.

The article addresses the relevance of the real estate sector in climate change control through the decarbonisation of buildings. It presents a case study of an investment portfolio artificially constructed from randomly selected buildings in different Spanish cities and with different uses, evaluated in terms of their structural and energy characteristics. The CRREM tool is used to evaluate the decarbonisation horizon of the buildings between 2018 and 2050, their total emissions and their cost, in relation to the maximum allowed in the agreements signed by the EU in Paris (COP21). From this calculation, an assessment is provided of when buildings will become energetically stranded (energy obsolete) assets and the cost of carbon emitted above permitted levels. These calculations lend transparency to the investment decision-making process facing building owners in the EU over the next 30 years.

Oriented fuzzy numbers are a convenient tool to manage an investment portfolio as they enable the inclusion of uncertain and imprecise information about the financial market in a portfolio analysis. This kind of portfolio analysis is based on the discount factor. Thanks to this fact, this analysis is simpler than a portfolio analysis based on the return rate. The present value is imprecise due to the fact that it is modelled with the use of oriented fuzzy numbers. In such a case, the expected discount factor is also an oriented fuzzy number. The main objective of this paper is to conduct a portfolio analysis consisting of the instruments with the present value estimated as a trapezoidal oriented fuzzy number. We consider the portfolio elements as being positively and negatively oriented. We test their discount factor. Due to the fact that adding oriented fuzzy numbers is not associative, a weighted sum of positively oriented discount factors and a weighted sum of negatively oriented factors is calculated and consequently a portfolio discount factor is obtained as a weighted addition of both sums. Also, the imprecision risk of the obtained investment portfolio is estimated using measures of energy and entropy. All theoretical considerations are illustrated by an empirical case study.

Business Organizations increasingly rely on publicly accessible communication infrastructures such as the Internet and Cloud computing, in order to manage their internal processes and offer their services to financial actors, businesses and ordinary people worldwide. However, little attention has been paid to embracing Software-as-a-Service (SaaS) philosophy for supporting business analysts in evaluating effectiveness and relevance of business information or finding patterns to direct them on more sources of data. This paper proposes a flexible architectural framework for modelling application services useful in supporting business decision processes. This architecture goes beyond the static schemas offered by data warehouse systems as it supports including data gathered from heterogeneous sources and added-value services offered in Internet or provided by Cloud infrastructures. Central to this architecture is the concept of dataspace as a reference model for structuring information relevant to a particular organization, regardless of its format and location. A case study of a real world implementation is presented dealing with supporting decisions in the real estate domain.

Abstract In May 2017, a workshop was held in Cairo, Egypt, to explore ways in which researchers doing research on topics related to the Nile Basin can work with journalists, aiming for better communication of science through media. The workshop hosted 40 participants, including communication specialists, scientists, academics, policy makers and NGOs' representatives from Egypt, Ethiopia, Sudan and international organizations. The workshop concluded that researchers and journalists needed more training in communicating and reporting science. In this respect, IHE Delft Institute partnered with SciDev.Net to develop and run an online course, 'Science Communication Skills for Water Cooperation and Diplomacy', which is described in this chapter. The main objective of the online course that took place between October 2018 and March 2019 was to build the capacity of scientists to engage with the media and effectively communicate science, and to deal with the River Nile as a vehicle of cooperation and development rather than conflict. Overall, the course had largely met the desired objectives. Most respondents greatly appreciated practical exercises, especially those on writing a press release and designing a communication strategy. The training platform was accessible and easy to use for most participants. However, there were areas that did not work as expected, most notably the length of the course.
