Developing A Sustainable Model for Impactful Academic Advising

The primary focus of this research is advising delivery models for community colleges. This capstone focused on the Virginia Community College System (VCCS), namely John Tyler Community College (JTCC). The research focused on delivering the most consistently supportive advising framework for faculty, staff, and students. A mixed-methods study was used by way of an online survey and in-person focus groups. Secondary data from the Integrated Postsecondary Education Data System (IPEDS) was used to compare JTCC to other colleges in the VCCS. This study also focused on best practices regarding academic advising and advisor development, evaluated the needs of current advising personnel, and provided academic advising strategies specifically for the JTCC student population. Using that information, this paper offers strategies for the successful implementation of new advising processes for institutions experiencing structural change

Genotoxic potential generated by biomass burning in the Brazilian Legal Amazon by Tradescantia micronucleus bioassay: a toxicity assessment study

<p>Abstract</p> <p>Background</p> <p>The Brazilian Amazon has suffered impacts from non-sustainable economic development, especially owing to the expansion of agricultural commodities into forest areas. The Tangará da Serra region, located in the southern of the Legal Amazon, is characterized by non-mechanized sugar cane production. In addition, it lies on the dispersion path of the pollution plume generated by biomass burning. The aim of this study was to assess the genotoxic potential of the atmosphere in the Tangará da Serra region, using <it>Tradescantia pallida </it>as <it>in situ </it>bioindicator.</p> <p>Methods</p> <p>The study was conducted during the dry and rainy seasons, where the plants were exposed to two types of exposure, active and passive.</p> <p>Results</p> <p>The results showed that in all the sampling seasons, irrespective of exposure type, there was an increase in micronucleus frequency, compared to control and that it was statistically significant in the dry season. A strong and significant relationship was also observed between the increase in micronucleus incidence and the rise in fine particulate matter, and hospital morbidity from respiratory diseases in children.</p> <p>Conclusions</p> <p>Based on the results, we demonstrated that pollutants generated by biomass burning in the Brazilian Amazon can induce genetic damage in test plants that was more prominent during dry season, and correlated with the level of particulates and elevated respiratory morbidity.</p

Lo sviluppo dell'economia monetaria determina presto diversi tentativi di imporre una "moneta unica": dalla dracma attica della lega ateniese al "solidus" costantiniano. In questo contesto, la dicotomia fra l'ammirazione per il denaro, con la fiducia nella stabilità e nell'autorità delle emissioni, e la diffidenza verso la ricchezza, che non dà la felicità e rende malvagi, percorre tutta la letteratura antica ed è confermata dall'analisi semantica dei concetti di denaro, di ricchezza, di povertà

A systematic review of the physical and chemical characteristics of pollutants from biomass burning and combustion of fossil fuels and health effects in Brazil

The aim of this study was to carry out a review of scientific literature published in Brazil between 2000 and 2009 on the characteristics of air pollutants from different emission sources, especially particulate matter (PM) and its effects on respiratory health. Using electronic databases, a systematic literature review was performed of all research related to air pollutant emissions. Publications were analyzed to identify the physical and chemical characteristics of pollutants from different emission sources and their related effects on the respiratory system. The PM2.5 is composed predominantly of organic compounds with 20% of inorganic elements. Higher concentrations of metals were detected in metropolitan areas than in biomass burning regions. The relative risk of hospital admissions due to respiratory diseases in children was higher than in the elderly population. The results of studies of health effects of air pollution are specific to the region where the emissions occurred and should not be used to depict the situation in other areas with different emission sources
