Towards a Structured Approach to Advance Sustainable Water Management in Higher Education Institutions: A Review
Full text linkThe aim of this paper is to investigate the measures adopted by higher education institutions (HEIs) for sustainable water management in university campuses. Rain and storm water harvesting and treatment, rain and storm water reuse, wastewater treatment and reuse and technologies for runoff reduction were found to be frequently undertaken. Sustainable approaches to water supply such as water-efficient appliances, irrigation algorithms and the use of drought-resistant plants have been adopted as well. In support, monitoring of consumed water and of rain and storm waters has been a widespread practice. Important considerations were given to the impact of the identified measures on campuses' energy consumption and greenhouse gas emissions. Nature-based solutions, employment of renewable energies and sustainable disinfection methods are measures to prioritize. Some wastewater technologies may deserve priority in virtue of their positive contribution to circular economy. Drawbacks such as groundwater and soil contamination due to wastewater reuse and the release of pollutants from fertilized nature-based technologies were identified. Despite their variety, it must be noted that many of these measures have generally involved rather limited portions of campuses, taken more for demonstration or pilot/full-scale research purposes. Additional measures not identified in the current review-for instance the prevention of pollution from micropollutants and waste mismanagement-should be implemented to boost HEIs' environmental sustainability. The findings of this review pave the way for a more structured implementation of water sustainability measures in university campuses
Circular Economy, Waste and Energy Management for a Sustainable Agro-tourism
No full textThe development of tourism worldwide has raised important concerns in studies based on the actions of tourism activities on community and environment. Nowadays, the research directions also focus on the continuous development of the agro-tourism sector. The connection between agro-tourism and sustainable development (SD) requires new frameworks concerning prototypes/patterns. Hence, the current research focuses on the circular economy (CE) agro-tourism sustainable development. The results and discussion presented in the current paper enhance the sustainable use of the resources within this field. Introducing CE concepts in this sector promotes the adoption of the latest sustainability targets in terms of production, consumption, and ethical choices. In addition, the agro-tourism structures offer the opportunity of involving different stakeholders (e.g., tourists and staff) in the implementation of initiatives to improve the levels of sustainability in this sector. The research presents a model of agro-tourism activities based on two case studies located in rural regions (Italy and Romania) aiming to improve the agro-tourism systems best practices towards SD goals under a CE perspective and taking into account the waste, energy, and air pollution sectors. Moreover, this paper underlines the role of the participants involved in agro-tourism by stimulating important awareness and attention within the agro-tourism sector's impact on environmental impact and consequently the local community well-being
Criteria for water management optimization in agrotourisms
No full textWater management optimisation is a topic that concerns many sectors. The present paper gives a contribution to understand the approach that can be adopted in the agro-tourism sector, often characterised by decentralised structures. The technological level to be adopted for water management depends on the local context. Solutions are already available for water losses prevention, water separation aimed to optimised management, treatment and recovery. The difficulty is their integration
Local Environmental Impact of Wood Combustion in Agro-Tourism Structures
No full textDomestic biomass fuel combustion can become significantly polluting if the process does not develop properly; problems related to exhaust gases emissions can actually occur in spite of the renewable nature of the fuel. The present article analyses the key questions that influence the quality of the biomass combustion process. Concerning this, high quality and controlled biomass and a technological appliance that assure a good combustion process development together with a proper utilization and maintenance of the whole system assume a significant role. A correct attention to the entire process reduces therefore the emissions dangerousness and improves the energy efficiency in exploiting the fuels heat value
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
