Este artículo presenta los resultados obtenidos a través del uso de herramientas informáticas (Provalis Research), también conocidas como CAQDAS (Computer Assisted Qualitative Data Analysis Software), para el análisis de los escritos de Peirce, las bases estadísticas de una cronología para su último periodo intelectual y la justificación de una posible periodización del Pragmaticismo, además de la descripción de ciertos descubrimientos realizados en nuestro trabajo de archivo sobre los documentos y manuscritos originales de Peirce. Este trabajo es una parte de nuestra investigación en la Universidad de Quebec en Montreal (UQAM) y la Biblioteca Houghton de la Universidad de Harvard.

The paper exposes an intervention proposal for an urban park in the city of Latacunga, Cotopaxi (Ecuador). The potential intervention seeks to promote the appropriation of public space where people and future users act as protagonists of the change, by contributing ideas and initiatives to create a place that considers their opinions, needs and suggestions. In order to achieve this, the proposal used the Wayfinder methodology, an avant-garde approach that assesses, plans, and acts in social-ecological systems to achieve sustainable, safe and fair transformations. Likewise, it proposes tactical urbanism activities as practical strategies to accomplish the project’s objective. The paper concludes that an intervention of this type is viable and capable of generating outstanding results regarding urban public space appropriation. Being viable, it is established that it can be executed in the short term, in accordance with the guidelines presented in the text.

Air contamination is one of the serious problems for the environment and the health of society. Air contamination risk assessment, health effects assessment tools are used to identify the place and time of public health effects and risk prevention strategies to reduce negative health effects. Considering that there may be a relationship between factors affecting risk, in this study, interactions between them are investigated using Fuzzy Decision Test and Experimental Evaluation Method (fuzzy DEMATEL). The cause of the health air contamination risk in an industrial area are the activity of industrial complexes and port (D+R=45.98, D-R=2.09) and the presence of hydrogen sulfide (46.82, 2.61), benzene (50.87, 2.87), sulfur dioxide (43.87, 4.32) and PM10 (53.51, 5.63) and the effects of these factors will affect the amount of carbon monoxide (39.56, -4.47), ozone (38.80, -4.20), nitrogen dioxide (50.33, -1.62) and PM2.5 (44.18, -1.26). Hospitals and nursing homes (49.01, -2.58), schools (50.99, -0.59), storage and industrial facilities, roads (45.72, -0.59), urban core (51.38, -0.55) and Natural zones, agriculture and waterways (48.86, -0.17) are affected by other factors. Population density is also affected by cause factors. Population density has a two-way relationship with PM2.5. The main human and social factors include GDP per capita and urbanization rate. Hydrogen sulfide has a one-way relationship with population density. People who work in certain industries may be exposed to higher amounts of hydrogen sulfide than the general population. These industries include the production of rayon textiles, pulp and paper factories, oil and natural gas drilling operations, and wastewater treatment plants. Therefore, by controlling the activity of industrial complexes, port and the amounts of hydrogen sulfide, benzene, sulfur dioxide and PM10 in the ambient air can be prevented from the effects after that.

In this paper, I reconstruct and analyze the Academic skeptics’ responses to the apraxia objection. This objection claims that the scepticism is a doctrine impossible to be put into practice because its theses lead to apraxia, that is, a state of lack or impossibility of action. The responses to the objection are divided into two kinds. The first one proves that assent is not a necessary condition to perform actions, so the skeptical advice to globally and wholly suspend assent does not lead to apraxia. The second one proves that it is possible to deliberate and rationally lead our actions without apprehensive impressions, so the skeptical thesis that apprehensive impressions do not exist does not lead to apraxia either. After some general considerations, in the first section of this paper I discuss Arcesilaus’ responses and in the second section Carneades’ responses.

The 60th number of the Cuadernos de Administración journal is the first one of 2018, a year in which we are consolidating this means of scientific dissemination, with the entry into several databases, the consolidation of our Editorial and Scientific committees and the process of internationalization of this publishing effort, which has promoted the dissemination of knowledge in Administration sciences throughout 42 years. On this occasion, the first paper entitled "Citizen participation through ICTs in the design of public policy in Colombia", presents the research results of a completed project, using data from 2013 and 2014, collected through surveys and interviews, to actors from different sectors in the department of Tolima, to assess the digitization strategy of the public sector. Opportunity strategies related to business competitiveness in restaurants in Mexico. Case: microenterprises in the municipality of Othón Payo. Blanco, Quintana Roo", is the second paper in this volume, wherein Mexican researchers analyze the relationship between organizational management and the business competitiveness of microenterprises in the restaurant sector in the municipality of Othón Payo Blanco, Quintana Roo. Among their main findings, they obtain that the business competitiveness in this region of Mexico is oriented towards technology and organizational culture, where strategic alliances are one of the strategies for achieving competitiveness within the sector. The third article is entitled "Quality Analysis of hotels service in Medellín through perceptual maps", is the result of a research wherefrom the perception of national and international guests staying in different hotels in Medellín, registered in the platform TripAdvisor, 57 hotels between 2005 and 2010 show that the factors most valued by guests are cleanliness, quality of rest and service above the location, price and comfort of the rooms, among others. "Sectorial adjustment costs induced by the Colombian pattern of international trade, 1991-2015", is the title of the fourth paper, wherein the authors analyze the adjustment costs induced by the Colombian international trade pattern for the 1991-2015 period; they calculate marginal intra-industrial trade indexes, adjustment costs and the use of the International Adjustment Cost Space and present different types of results. The fifth article, entitled "Craftsmanship and champeta: cultural industries and local development in the municipalities of Clemencia and María la Baja in the department of Bolívar", seeks to highlight the production process of cultural goods and services within the champeta manifestations and handicrafts in the municipalities of Clemencia and María la Baja in the department of Bolívar, where they are able to demonstrate local capacities for the creative production of goods. Finally, "Multi-business companies: The Leonisa case" is the name of the sixth paper in this volume, which presents the study of the joint management of multi-business companies, in an exploratory manner in the case study of the company Leonisa, a Colombian multi-business company in the textile sector. Among the relevant findings are the company not having a corporate center (CC) with a formal structure, but a multi-divisional structure from which to manage the business as a whole. It is important to remember that the content of each of these six papers is their authors' absolute liability and does not compromise the Universidad del Valle, nor the Faculty of Administration Sciences, and their dissemination is carried out for academic purposes, as a contribution to the scientific development of the area and to encourage debate on each of these issues. We thank each of the authors, the professional work of the referees who accompanied us in this issue, and especially you, our readers, for thinking of this means of dissemination as an option for consultation in the academic work you do. We hope to have publications from all members of this extended scientific community that we are trying to build and consolidate.

Critical and pancritical rationalism were mainly debated in the second half of the XXth century, however a new important paper on pancritical rationalism has been published recently, and hence a critical commentary of this recent publication is required, one is offered here.
