The purpose of this paper is to present a new low‐cost system based on a spherical robot for performing moisture monitoring in precision agriculture.

The work arose from the necessity of providing farmers with alternative methods for crop monitoring. Thus, after analysing the main requirements, a spherical robot was chosen as a tentative approach. The presented work summarizes the work carried out in selecting the basics to apply in the robot, as well as its mechanical and electronic design. After designing and constructing the robot, several tests have been performed, in order to validate the robot for performing monitoring task and moving on different types of soil.

The performed tests reveal that spherical robot is a suitable solution for performing the task.

Some improvements in control should be applied in order to reach a fully autonomous navigation in very slippery soils. Nevertheless, the performance of the robot in teleoperated mode allows validating of the system.

The robot turned out to be friendly and harmless in its use for this application. The cost of final series will be affordable in comparison with the cost of other methods. Endurance of the robot can be considered as fair.

The paper presents a new tool for farming based on non‐common robot.

This paper aims to present a system that is fully capable of addressing the issue of detection, tracking and following pedestrians, which is a very challenging task, especially when it is considered for using in large outdoors infrastructures. Three modules, detection, tracking and following, are integrated and tested over long distances in semi-structured scenarios, where static or dynamic obstacles, including other pedestrians, can be found.

The detection is based on the probabilistic fusion of a laser scanner and a camera. The tracking module pairs observations with previously detected targets by using Kalman Filters and a Mahalanobis-distance. The following module allows to safely pursue the target by using a well-defined navigation scheme.

The system can track pedestrians from static position to 3.46 m/s (running). It handles occlusions, crossings or miss-detections, keeping track of the position even if the pedestrian is only detected in 55/per cent of the observations. Moreover, it autonomously selects and follows a target at a maximum speed of 1.46 m/s.

The main novelty of this study is the integration of the three algorithms in a fully operational system, tested in real outdoor scenarios. Furthermore, the addition of labelling to the detection algorithm allows using the full range of a single sensor while preserving the high performance of a combined detection. False-positives’ rate is reduced by handling the uncertainty level when pairing observations. The inclusion of pedestrian speed in the model speeds up and simplifies tracking process. Finally, the most suitable target is automatically selected by a scoring system.

This paper aims to describe the likely positive effects of alpha-linolenic acid supplementation on the lung and the negative effects of it on the adipose tissue of COVID-19 patients.

This paper focuses on investigating the effects of alpha-linolenic (ALA) on the respiratory system and adipose tissue of COVID-19 patients.

ALA can help human respiratory system by improving lung damage. On the other hand, when it comes to adipose tissue, it can induce the overexpression of glucose transporter-4 gene and impair COVID-19 prognosis.

Despite the inconclusive pieces of evidence, improving the quality of patients’ diet may help mitigating their risk of developing severe COVID-19 infection. Further research studies are necessary to help finding a safe ALA recommendation focused on preventing and improving lung damage, as well as on stopping adipose cells from working as COVID-19 reservoirs.

Latin America has not been exempted from the effects of the COVID-19 pandemic. Hence, this study aims to identify the actions of 50 main multilatinas to face the pandemic.

A qualitative content analysis was conducted on newspapers published in Latin America and corporate websites from March 2020 to April 2020, during which the multilatinas took their first actions toward the pandemic.

Results identified 106 actions taken by multilatinas in social, operational, philanthropic and financial areas. This paper analyzes the results, discuss the implications for business theories and develops three theoretical propositions.

First, this study can serve as a reference for business decision-makers as it offers guidance in taking actions during a pandemic. Second, it highlights the importance of the speed of responses to unforeseen challenges. The study recommends that business managers include in their contingency plans procedures for addressing unforeseen situations, such as the pandemic, with a focus on increasing their response capacity.

The importance of this study lies in understanding multinational enterprises’ (MNEs) initial actions taken during unexpected disasters and rare events. This study fills two important gaps in the business literature that have not been addressed in the Latin American context, namely, the actions taken by MNEs facing a public health disaster and how MNEs cope with disastrous and rare events.

Una técnica cualitativa de análisis de contenido fue llevada a cabo en periódicos publicados en América Latina y páginas web corporativas entre marzo y abril de 2020, durante los cuáles las multilatinas tomaron sus primeras acciones hacia la pandemia.

Los resultados identificaron 106 acciones tomadas por las multilatinas en las áreas sociales, operacionales, filantrópicas y financieras. Además, se analizan los resultados, discuten las implicaciones para las teorías de negocios, y se desarrollan tres proposiciones teóricas.

Primero, este estudio puede servir como referente para los tomadores de decisiones ya que ofrece una guía de acciones tomadas durante la pandemia. Segundo, se muestra la importancia de la velocidad de respuesta a retos imprevistos. El estudio recomienda que los gerentes incluyan en sus planes de contingencia planes y procedimientos para abordar situaciones imprevistas, tales como la pandemia, enfocados en incrementar su capacidad de respuesta.

La importancia de este estudio recae en el entendimiento de las acciones tomadas por las empresas multinacionales durante desastres inesperados y eventos raros. Este estudio cubre dos huecos importantes en la literatura que no han sido abordados en el contexto de América Latina: las acciones tomadas por las multinacionales encarando un desastre de salud pública y como las multinacionales afronta los eventos raros y desastres.

This chapter is intended to present the onset, evolution, and decline of Compañía Minera El Zancudo, considered the largest Colombian company in the nineteenth century. Additionally, the chapter will examine its role in both the development of manufacturing industries and the introduction of modern capitalism in the country.

The case is based on secondary information collected according to a documentary research method in which the authors selected, categorized, interpreted, and confronted different sources concerning El Zancudo.

The inception and evolution of El Zancudo involved local and foreign knowledge, techniques, and capital investments that contributed to the company growing to the point of reaching the unprecedented figure of 1,350 workers in the year 1890. Its transition from a failed local mine to a prosperous and intricate business group is full of referrals and links to foreign investment, knowledge transfer, industrial development, and an orientation toward entrepreneurship that contributed to the understanding of subsequent enterprises not only in the Antioquia region but also across the entire country.

This case study was written using limited reliable secondary sources about El Zancudo. Other significant Colombian companies in the nineteenth century (Ferrería de Pacho, Ferrería de Amagá, Empresa Textilera de Samacá, and Cervecería Bavaria) and their links to El Zancudo were mentioned but not deeply analyzed in this chapter.

The clear-cut causes that led El Zacudo to close its operations within the first decades of the twentieth century are worthy of discussion, not only by scholars and business practitioners, but also by policy makers in order to understand the phenomenon and possibly prevent existing companies from failing in a similar manner.

This case brings together the scattered literature on El Zancudo and analyzes the drivers and consequences of both its rise and fall, taking into consideration the specific historical, political, and economic contexts, furthermore, it establishes some linkages between this case and other companies under similar situations.

This paper aims to analyze the potential and limitations of donor-financed management tools that seek to promote corporate social responsibility (CSR) in small and medium-sized enterprises (SMEs) in developing countries. Drawing on key insights from three streams of literature relating to institutional theory, critical perspectives on CSR in developing countries and the literature on CSR and SMEs in the developing world, the potential and limits of donor-financed management tools aimed at promoting CSR in developing country SMEs are analyzed.

Using official UN and Organization of Economic Cooperation and Development lists of all multilateral and bilateral donor agencies, 38 donors that might have produced such CSR tools were identified. The authors contacted them via e-mail and/or telephone, and conducted an extensive Internet search with the aim of identifying whether they had developed management tools aimed at promoting CSR in SMEs in developing countries. The authors then scrutinized the contents of the 11 tools identified and examined the extent to which these tools accord attention to contextual differences and specific peculiarities of institutional environments in developing countries; the extent to which these tools account for the silent or sunken aspects of CSR which have been prominently highlighted in the SME – CSR literature; and the extent to which these tools accord attention to the paramount concern for poverty alleviation in developing countries.

Overall, the analysis testifies to the continued predominant orientation of these tools to the context of larger firms in developed countries, with insufficient tailoring or customization to the specific realities of SMEs in the South.

In-depth interviews with aid agency personnel, SMEs, workers or community members were not conducted. Hence, this study should be seen as an initial, exploratory desk study of the potential and limits of management tools aimed at promoting CSR in SMEs in the developing world.

It is suggested that donor agencies could develop such tools in a bottom-up fashion by first mapping the silent CSR practices of SMEs in developing countries and then use this as a basis for strengthening existing CSR activities in SMEs instead of trying to impose new priorities from the outside. This might enhance the local relevance and applicability of these management tools.

The study is likely to be the first analysis of the potential and limits of management tools that are developed by donor agencies with the aim of promoting CSR in SMEs in developing countries.
