    Consciousness and Environmental Ethics: Eco-Critical Perspectives in the Goan Novel Tivolem

    Get PDF
    Over the past decades, the world helplessly witnessed the increasing unpredictability, in fact ‘Erratic chaos of the environmental phenomena. Nature is avenging the destruction done to it. Ecological chaos and disorder have become the norm due to misuse of the Earth’s resources. As environmental consciousness grows, writers have begun to responsibly portray the man-nature relationship in texts. Similar or Animal Studies, Green Cultural studies, Ecofeminism, ecocriticism is gaining popularity for its discerning consciousness of the environment in relation to culture. Ecocriticism is a new movement which aims at pointing out the dangers of man’s anthropocentric dominion of Nature. This Paper seeks to explore the ecocritical perspectives reflected in the novel Tivolem and the eco-consciousness of Goan resources created by this diasporic Goan novel in order to bring about sustainable eco management

    The industrial microalga Tetraselmis sp. CTP4 is a promising candidate for aquaculture feed, novel food, cosmeceutical and nutraceutical due to its balanced biochemical profile. To further upgrade its biomass value, carotenogenesis was investigated by testing four environmental factors, namely temperature, light intensity, salinity and nutrient availability over different growth stages. The most important factor for carotenoid induction in this species is a sufficient supply of nitrates leading to an exponential growth of the cells. Furthermore, high temperatures of over 30 degrees C compared to lower temperatures (10 and 20 degrees C) induced the accumulation of carotenoids in this species. Remarkably, the two different branches of carotenoid synthesis were regulated depending on different light intensities. Contents of beta-carotene were 3-fold higher under low light intensities (33 mu mol m(-2) s(-1)) while lutein contents increased 1.5-fold under higher light intensities (170 and 280 mu mol m(-2) s(-1)). Nevertheless, highest contents of carotenoids (8.48 +/- 0.47 mg g(-1) DW) were found upon a thermal upshift from 20 degrees C to 35 degrees C after only two days at a light intensity of 170 mu mol m(-2) s(-1). Under these conditions, high contents of both lutein and beta-carotene were reached accounting for 3.17 +/- 0.18 and 3.21 +/- 0.18 mg g(-1) DW, respectively. This study indicates that Tetraselmis sp. CTP4 could be a sustainable source of lutein and beta-carotene at locations where a robust, euryhaline, thermotolerant microalgal strain is required.Funding Agency Portuguese Foundation for Science and Technology UID/Multi/04326/2019 SFRH/BD/115325/2016 SFRH/BD/140143/2018 SFRH/BD/105541/2014 0055 ALGARED+ 05 INTERREG V-A -Espana Portugal project national Portuguese funding PPBI-POCI-01-0145-FEDER-22122 Nord Universityinfo:eu-repo/semantics/publishedVersio

    Resilience In the Face of Social and Environmental Impacts

    The dynamics of the systems present in the Amazon require a detailed view of the aspects involving human actions and their consequent interactions with the forest. The impacts caused by this relationship have been the subject of numerous studies aimed at understanding the responsiveness to these impacts, risks, and vulnerabilities of the environment subject to risk factors. The general goal of this paper is to conduct a theoretical and conceptual study on resilience in the face of socioenvironmental impacts in the Brazilian Western Amazon. The specific goals are to contextualize the concepts of situational resilience in the face of environmental impacts, to address the main definitions of environmental impacts in the Amazon, and analyze the approach in the face of the Amazon environmental heritage. Regarding the problem, the following question was proposed: how is resilience characterized in the face of social and environmental impacts? In order to answer this question, a theoretical-conceptual review based on the Contingency Theory was conducted to support the conclusions. In order to reach this goal, we sought the conceptualization of resilience in the face of environmental impacts, the search for the main definitions of environmental impacts in the Brazilian Amazon and some concepts about the Amazonian environmental heritage in a qualitative approach by collecting data through qualitative research for further analysis of the problem and literature review, in order to build knowledge for the theoretical foundation using the Contingency Theory, which springs from environmental conditions to actions that minimize the impacts of human action

    LEADERSHIP THEORIES: A SYSTEMATIC REVIEW BASED ON BIBLIOMETRIC AND CONTENT ANALYSIS METHODS

    Get PDF
    In this article, we investigated the existing knowledge of Leadership theories aiming at mapping the evolution of the main theories up to 120 years through collaborative networks. N = 3,968 publication records were extracted from Google Scholar through keyword searching, resulting in approximately one million citations. Based on these records, the study performed bibliometric analysis, including text network, citation, trend and content analysis, revealing themes in the field. The findings are helpful to scholars, students, leaders, and other practitioners, to gain a deeper understanding of the timeline, geographical spread, and development of theories. A careful literature review revealed that the scholarly research revolves mostly around (i) transformational Leadership; (ii) Contingency, and (iii) Leader-Member Exchange (LMX) theories. Furthermore, the number of citations on leadership more than tripled in the last two decades and might double in the coming decades. This study also suggests recommendations for future studies

    The Photosynthetic Response of Northern Red Oak (Quercus rubra L.) and American Chestnut (Castanea dentata (Marsh.) Borkh) Under Varying Light Intensity and Weed Competition

    Although widely distributed across Indiana and the United States Midwest, conifer plantations consist largely of non-native species that are of no value to the state’s forest products industry. This project’s goal is to develop science-based protocols and specific silvicultural prescriptions for successfully converting conifer plantations to higher value native hardwoods. Quantifying photosynthesis rate in a plant is an important tool to help us discern the best methods for implementing conifer conversion. Seedlings from two different native species, northern red oak (Quercus rubra L.) and American chestnut (Castanea dentata (Marsh.) Borkh), were distributed among three different silvicultural cutting treatments (control, thinning and clear cut). Inside each one, two distinct categories of herbaceous control treatments (weed control and no weed control) were installed. Using an AccuPAR LP-80 sensor, canopy PAR (photosynthetically active radiation) interception was measured. Photosynthetic capacity was assessed with a LICOR 6400-XT analyzer to evaluate efficiency in resource use (water, light, gas exchange) and productivity. Among the treatments, clear cut presented maximum PAR intensity, followed by thinning and control, respectively. Both American chestnut and northern red oak seedlings demonstrated the highest photosynthesis rate (Amax) under high light conditions (clear cut), though photosynthesis of chestnut was greater than that of northern red oak. No significant differences were found between species in the weeding treatment for photosynthesis. Results of this study will provide valuable silvicultural prescriptions to Non-Industrial Private Forest (NIPF) landowners, forestry professionals, as well as state and federal agencies in Indiana and other Midwestern states
