Nothofagus pumilio forests constitute the most economically important forest stand in southern Argentina and Chile. Total volume stocking and volumetric yield vary according to site quality, degree of occupation, growth stage and forest history of the stand. The objective of this work was to evaluate the stocking and the productive potential in quantity and quality of products for the sawmilling industry, using three harvesting systems (short logs, long logs and complete shafts) in the protection cut of a N. pumilio forest of site quality III in Tierra del Fuego (Argentina). The trials were conducted in an irregular mature forest with two strata and abundant regeneration (3.0 ha; RDI 93.8–113.4%). Total volumes varied between 726.5 and 850.3 m3∙ha-1, with a volume/basal area ratio of 11.8 to 12.1 m3∙m-2. The harvesting rates obtained were: 45.5% for complete logs, 21.3% for long logs and 22.4% for short logs. A model was used to estimate the timber volume for each system, where full shafts resulted in a significant increase in timber volume. Considering new alternatives in the planning of harvesting in forest management for N. pumilio forests, such as the system of complete shafts, allows obtaining higher harvesting rates, increasing the benefits for the forestry company and minimizing the damage to the forest, due to the shorter distance of the machinery in the forest harvesting.
Technological management has promoted distinctive characteristics in the socio-productive development of the regions. Its usefulness in entrepreneurial activity is studied to design the architecture of a technological observatory as an intelligent system for entrepreneurship in Latin America. Using a descriptive-explanatory method, data obtained from the application of two instruments directed to 18 experts in information and communication technologies and 174 entrepreneurs distributed 92 in Lima-Peru and 82 in Santiago de Cali-Colombia are processed. The findings show informational and training barriers and a weak or non-existent technological platform for effective entrepreneurial development. Added to the low development of plans and alliances mediated by technologies, whose experience supports public policies that strengthen entrepreneurship as an emerging economy. The architecture supports the functional and operational aspects of the system. Its scalability in other regions dynamizes the services-processes required prior to the detection of needs directed towards the projection of sustainable entrepreneurship.
This research, with a qualitative approach, is based on a literature review and a press analysis related to mergers, acquisitions and dissolutions of Higher Education Institutions in South America. Our findings evidence a gap in the academic literature for analyzing and understanding these processes. The literature on the subject is scarce; however, the press has recorded them in a constant way. While in the past this phenomenon was mainly among public universities, currently it is a fundamentally private trend. The main reasons to carry out this process by Higher Education Institutions are those related to geographic expansion or positioning (for merger processes), absorption and concentration of institutions by groups of interest (for merger processes, acquisition) and, the crisis resulting from the financial-administrative management of the institutions, as well as the non-compliance with national and international quality standards designed by accreditation agencies and institutions (for dissolution processes). On the contrary of some literature results, in any of the processes the search for prestige or reputation by the institutions was detected as a reason.
The global climate governance process will have a profound impact on geopolitical relations, and, at the same time, these will determine the direction of cooperation in international climate governance. The European Union and the United States are the most important players in the global governance of climate change, and their competing policy orientations and dynamics have a major impact on trends in this field. In this context, Africa is the region most vulnerable to climate change, and the climate issue in Africa has become one of the frontiers of competition between major powers. Indeed, major powers are increasingly competing in Africa, primarily in the areas of climate leadership, program provision, and capacity building. The study is based on the review of articles and research works regarding the global climate change strategies, especially in AFRICA (2020–2024); it also collected information and statistics from the websites and reports of world banks. In the future, the European Union and Africa should work together to build a new era of strategic partnerships to fight climate change. To do this, they should strengthen their strategic collaboration in global climate governance, look for new ways to work together in old ways, and make their cooperation more effective and efficient.
Latin America is increasingly contributing to scientific research on leadership, although less than other regions. What are the predominant paradigms on leadership within the scientific community in Mexico? The article reviews doctoral dissertations on leadership from the National Autonomous University of Mexico (UNAM) and the Anahuac University of Mexico (UA) defended before 2021. The findings highlight that 1) the number of doctoral dissertations has grown from 2016 onwards, especially in educational leadership. 2) In both universities a “functionalist” paradigm prevails, based on the transformational leadership model. 3) Two other leadership paradigms are present, referred to in this article as ‘political’ and ‘humanistic’. 4) These three paradigms have their characteristics and preferences in terms of research methodology, language, and reference authors. 5) The use of a paradigm is associated with the type of faculty rather than the type of university (public or private): in business faculties the functionalist paradigm predominates, in education faculties the humanist paradigm, and in political science or communication faculties the political paradigm. In conclusion, it is recommended to confirm the exploratory result obtained and to promote the dialogue between leadership paradigms.
