El trabajo examina la productividad artística durante el ciclo de vida de tres fotógrafos latinoamericanos sobresalientes en el Siglo XX: Manuel Álvarez Bravo (México), Sergio Larraín (Chile), y Sebastião Salgado (Brazil). El análisis desarrolla recuentos empleando libros sobre la historia del arte y otras fuentes de análisis de expertos sobre la materia, siguiendo la metodología de contribuciones en la literatura económica [David W. Galenson, 2007, Old masters and young geniuses: The two life cycles of artistic creativity, Imprenta de la Universidad de Princeton]. La investigación identifica a Manuel Álvarez Bravo como ‘innovador conceptual’, característica que temprano en su carrera llamó la atención de los surrealistas franceses. En contraste, Sergio Larraín y Sebastião Salgado logran sus contribuciones a la fotografía operando como ‘innovadores experimentales’. La investigación también reúne y evalúa indicadores en base a colecciones de museos y retrospectivas selectas para medir la robustez de las conclusiones que surgen de las narrativas. Los resultados de la investigación pueden ser útiles desde los puntos de vista académico y de política pública: entender la productividad artística durante el ciclo de vida puede contribuir en discusiones sobre cómo asignar los fondos públicos para las industrias creativas.

Este documento muestra los resultados de un ejercicio de valoración contingente llevado a cabo para evaluar los impactos ambientales causados por la disposición de 56,000 toneladas de cenizas de roca en la República Dominicana en 2003 y 2004. En marzo de 2007, el gobierno dominicano y la Corporación AES llegaron a un acuerdo legal por USD 6 millones en multas para evitar un largo proceso judicial. La disposición a pagar por un programa de observación y monitoreo para prevenir y mitigar los impactos ambientales causados por la ceniza de roca se estimó en USD 194 millones en 2007, reflejando las pérdidas de bienestar social experimentadas por la sociedad dominicana en ese momento.

Accounting applied to the public sector in recent years has been driven by the process of convergence to international standards. In view of this movement, increase the need to adhere to the procedures for measuring fixed assets in public sector bodies and entities. In this context, the study aimed to evaluate the degree of application of the procedures for measuring the active assets of Brazilian universities and federal institutes to international accounting standards. Through the adoption of the grouping criterion, questionnaires were sent to 102 Federal Institutions of Higher Education (IFES) and 49% of responses were recorded. The survey results show that public entities, which concern the measurement and disclosure of assets, are at odds with the process of convergence of the Brazilian public sector to international accounting standards. To achieve this process, investments in technology, training, professional development, awareness of managers and training of multidisciplinary teams are necessary. In addition, the study points out the need for more effective collection by regulatory bodies in relation to compliance with standards, specific legislation and the Accounting Manual Applied to the Public Sector.  

The particularities of the environment force organizations to adapt to a world where change is constant and immediate; therefore, the search for new strategies to achieve and maintain a competitive advantage is necessary to face current challenges. This article aims to present a literature review of organizational change management, showing the contributions of the last ten years. We identify an increasing association in several variables related to organizational change management, including planning and strategy, leadership, culture, innovation, and resistance to change. Our conclusions indicate that these variables are essential for strategical changes during periods of uncertainty, and their adequate assessment significantly increases the company's chances of success.

The quarantine produces the benefit of the statistical value of the years of life saved and generates a cost equal to the income ceased to be produced by the population with confinement, which is represented in the model formulated here. Contagion and mortality rates with and without quarantine are incorporated, the difference between the two states being of the same benefit. The labor of the confined population is assumed to be the only cost, which multiplied by its quantity, produces as a result its cost. The fundamental equation that equals cost to quarantine benefits is then used to determine the optimal time to remove confinement. The benefit of quarantine comes from the decrease in the pandemic’s spread factor, and if the parameters of the equations are known, they can be applied for short periods of time to determine the time of removal. This process is applied to the case of the Dominican Republic using a ten-day period, concluding that after 50 days, with a spread factor of 0.9, the cost of quarantine was greater than its benefit.

The purpose of this essay is to calculate the Backward Participation in Global Value Chains index of Puerto Rico and to assess the extent to which manufacturing industries create backward and forward linkages within the economy. The open quantitative model of the input-output analysis developed in this paper uses the total matrices of inter-industrial transactions. The results indicate that Puerto Rico exhibits one of the highest relative backward participation rates in GVC in the first years analyzed when compared to 39 OECD countries, ranking even in the first two places. However, in the last year considered, the Puerto Rican index experienced the largest relative decrease, falling 15 percentage points and standing at the average of the Latin American pairs with which it is compared. In addition, the industries that participate in the scheme remained with few or no linkages, except petrochemicals in the first two years. For the first time in the literature, this paper measures the rate of backward participation in global value chains of Puerto Rico and combines it with an analysis of key industries, contributing to closing the gap of empirical studies of Latin American and Caribbean countries on the subject.

This document presents estimates of the contagion rate and the reproductive number R0 of COVID-19 for the Dominican Republic, contrasting them with those identified in other countries. To estimate the model, we adapt the state-space framework to the canonical SIR epidemiology model. With data obtained as of April 16, 2020, the results indicate a decreasing trend in secondary infections (R0), suggesting that distancing policies have been effective in reducing the spread of the virus. However, in order to reduce the actual levels in secondary infections to the levels of those countries that have been most successful in containing the epidemic, the results also suggest that existing measures should be strengthened and extended.

No summary.

The named COVID-19 pandemic has brought changes not only in health policies at the global level, it has also tested the governments of different countries, their economic, monetary and taxes policies, companies and their finances, as well as employees, who have undergone a process of adaptation to transit to what has been called the new normality. Therefore, this writing emphasizes the impact that COVID-19 pandemic has had in Mexico and its side effects in three core areas for the country and its organizations, such as: the human factor of companies, business finances and the taxes area. Likewise, it provides a critique of the measures proposed and implemented by the Government of Mexico to face the first repercussions of the pandemic in the three cited core areas. Finally, the manuscript concludes with a perspective towards 2021 of the areas of human and organizational behavior (human factor), financial-business and taxes.

This article aims to analyze the impact of COVID-19 on the integration and coordination mechanisms of organizational architectures. I present a comprehensive model to analyze organizational architectures based on several organizational theories, including structural contingency, structuralism, resource dependence, resources and capacities, situational, human relations, and organizational development. This article emphasizes how organizations need to adopt changes that articulate with a sense of opportunity the strategies, the structure, the socio-technical systems, the control mechanisms, the incentives, and the cognitive factors of people with the environment. It also explains why companies are required to adopt changes to survive under the new conditions generated during the COVID-19 pandemic and how they can create the requirements for developing new working habits, coordination mechanisms, and integration of organizational units for effective decision making. These elements of the organization's architecture are essential factors for its survival and good performance under the COVID -19 pandemic.
