Anthropogenic emission inventory and spatial analysis of greenhouse gases and primary pollutants for the Galapagos Islands.

Climate change and air pollution are critical challenges that humanity is currently facing. Understanding the sources of emissions released into the atmosphere is of great importance to evaluate the local footprint, the impacts of human activities, and the opportunities to develop and implement solutions to mitigate emissions and adapt to climate change particularly in vulnerable places like the Galapagos Islands. In this study, we present an anthropogenic emissions inventory for Santa Cruz, San Cristobal, and Isabela Islands in which emissions were spatially mapped for greenhouse gasses (GHGs) and primary pollutants (PP). Emissions were estimated for the energy stationary sources, energy mobile sources, waste, and other sectors, and emissions for 2019 were spatially distributed along with an uncertainty assessment. Results demonstrated that energy mobile sources which are aerial, terrestrial, and maritime transportation generated the most significant emissions in the Galapagos Islands in terms of PP and GHGs. In fact, maritime transportation was the highest one in 2019, at 41% of total CO2 emissions for Galapagos, with the most predominant PP being NOx and CO. The aerial transportation made up 36% of emissions, and the electricity generation contributed 15%. Emissions from waste and other sectors comprise a smaller percentage relative to the rest of the emission sectors. These results highlight the strong dependency of the islands on fossil fuels for transportation and electricity generation. Alternatives to mitigate and reduce emissions from the islands are discussed. This spatially mapped emissions inventory for the Galapagos Islands represents a powerful tool to make informed decisions to contribute to the long-term sustainability of the archipelago.

Fatores de evasão no ensino superior: uma revisão de literatura / Dropout factors in higher education: a literature review

A evasão no Ensino Superior constitui preocupação internacional com impacto nas Instituições de Ensino Superior, em geral, e nos percursos de carreira individuais, em específico. Para prevenir esse fenômeno e apoiar tanto instituições como estudantes na sua tomada de decisão, urge identificar fatores de evasão no ensino superior. Apresenta-se revisão de artigos publicados em revistas científicas internacionais entre janeiro 2014 e dezembro 2018, com base no Modelo Longitudinal de Evasão Institucional. A pesquisa foi realizada em quatro bases de dados, com combinações das palavras-chave dropout, departure, academic adjustment, college adjustment, academic integration, social integration e higher education. Foram lidos integralmente 24 artigos que satisfaziam critérios de inclusão. Procedeu-se à descrição dos artigos e o conteúdo foi sistematizado em meta-síntese. Identificaram-se fatores relativos a atributos prévios à entrada no ensino superior; objetivos e compromissos prévios e posteriores a essa entrada; experiências institucionais; integração acadêmica e social. Identificaram-se ainda medidas de sinalização de evasão. Discutem-se implicações para a investigação, para serviços e políticas das Instituições de Ensino Superior.

La evasión en lo Enseñanza Universitaria constituye preocupación internacional con impacto en las Instituciones de Enseñanza Universitaria, en general, y en los recorridos de carrera individuales, en específico. Para prevenir ese fenómeno y apoyar tanto instituciones, como estudiantes en su toma de decisión, es urgente identificar factores de evasión en la enseñanza universitaria. Se presenta revisión de artículos publicados en revistas científicas internacionales entre enero 2014 y diciembre 2018, con base en el Modelo Longitudinal de Evasión Institucional.

Se identificaron factores relativos a atributos previos al ingreso en la enseñanza universitaria; objetivos y compromisos previos y posteriores a esa entrada; experiencias institucionales; integración académica y social. Se identificaron, aún medidas de señalización de evasión. Se discuten implicaciones para la investigación, para servicios y políticas de las Instituciones de Enseñanza Universitaria.

Dropping out of Higher Education is an international concern with an impact on Higher Education Institutions, in general, and on individual career paths, in particular. In order to prevent this phenomenon and support both institutions and students in their decision-making, it is urgent to identify evasion factors in higher education. A review made in published articles in international scientific journals between January 2014 and December 2018 is presented, based on the Longitudinal Institutional Evasion Model. The search was carried out in four databases, with combinations of the keywords dropout, departure, academic adjustment, college adjustment, academic integration, social integration, and higher education. Twenty-four articles that met the inclusion criteria were fully read. The articles were described and the content was systematized in meta-synthesis. Factors related to attributes prior to entering higher education were identified; objectives and commitments prior and subsequent to this entry; institutional experiences; academic and social integration. Evasion signaling measures were also identified. Implications for research, services and policies of Higher Education Institutions are discussed.
