EVALUATING THE ENVIRONMENTAL IMPACTS OF ANIMAL BYPRODUCT UPCYCLING: THE CASE OF BEEF KIDNEY UTILIZATION IN CEVAPCICI.
No full textThe global population is growing and expected to reach 9.7 billion by 2050, and with this, the food demand is expected to rise by 70%. The current food system has a significant impact on the environment, and this impact is likely to increase as food demand continues to rise. Simultaneously, about 40% of all food produced is lost or wasted along the supply chain globally. To eliminate this problem, many initiatives, both in Sweden and the EU, prioritize the prevention of food loss and waste, as well as the circular usage of byproducts that would otherwise be composted or used as animal feed. One of the initiatives that focuses on eliminating food loss and waste in Sweden is Blod & Rova. In this project, beef kidney, which is considered food loss and waste in Sweden and is rarely consumed by humans, was utilized in new novel food products: Balkan Cevapcici and Kimchi Cevapcici, which are expected to be served in the public catering sector in Sweden. This study examines the environmental impact of Balkan Cevapcici and Kimchi Cevapcici, which are substitute parts of the traditionally used lean meat with beef kidney. It also examines and analyzes the perspectives of the chefs expected to serve the novel food products to understand the challenges and opportunities that can arise when serving the novel food products. This study has two objectives: 1) to quantify the environmental impact of incorporating beef kidney in the Balkan and the Kimchi Cevapcici, compared to the traditional Cevapcici, and 2) to investigate the opportunities and challenges perceived by chefs who are expected to purchase and prepare meals for school children and the elderly as part of the public catering sector. An attributional life cycle analysis of the Balkan Cevapcici, Kimchi Cevapcici, and Traditional Cevapcici was conducted from a cradle-to-farm gate using the functional unit of 1 kg of protein. Three cases were analyzed: 1) Swedish market-average data with zero burden allocation to the kidney (reflecting it being food loss and waste in the current system), 2) Swedish-grown ingredients data with zero burden allocation to the kidney, and 3) a what-if analysis in which the kidney bears the full allocation. The impact categories assessed in this study are carbon footprint (CO2e), land use, water use, and new Nitrogen and Phosphorus input. The results showed a reduction in the environmental impact for the Balkan Cevapcici and Kimchi Cevapcici in all impact categories and scenarios compared with the Traditional Cevapcici. Stakeholder insights were obtained through thematic analysis of surveys. The results showed a general positive tendency toward using the Balkan Cevapcici and the Kimchi Cevapcici, with some doubts regarding sensory experience, communication, and labeling. N

ENERGY LITERACY AND BEHAVIOR AMONG UNIVERSITY STUDENTS. THE CASE OF UPPSALA UNIVERSITY, CAMPUS GOTLAND.
No full textEnergy is one of the most critical elements that support societies in the modern world. As with anything else, energy is a limited resource, and saving it is essential for a fossil-free future where one is aware of their energy consumption and knows what is needed to save it. Recently, Europe has been faced with severe energy shortages where Sweden for example was under the threat of blackouts in 2022/2023. As a way to mitigate the problem, The EU introduced a law that obliges individuals and institutions to reduce their energy consumption during peak hours. In Sweden, this was translated into “Varje kWh räknas” or every kilowatt-hour counts campaign in order to promote energy saving in society. Uppsala university is one of the institutions that had to reduce the energy consumption where students play a role in this energy saving. On the other hand, energy literacy is defined as the way people understand energy, how it is being used, and the attitudes regarding saving it. Previous research (such as Cotton et al., 2015; DeWaters and Powers, 2011; Blasch et al., 2017) about energy literacy tended to focus on various societal groups when investigating the three different domains of energy literacy: cognitive, attitude, and behavior. The cognitive domain is defined as the knowledge related to energy basic rules and concepts, while the affective domain is defined as the attitudes toward energy such as beliefs, values, feelings, etc. Behavioral literacy is the intentions, involvement, and decisions one makes in relation to energy and energy saving. This study aims to explore themes and opinions in energy behaviour, perception, and literacy among students in order to understand the current ways energy literacy is being promoted and taught at Uppsala University and the wayes to imporove it. This was done by providing answer to the resurch question: What cognitive, behavioural, and affective knowledge do students have about the nature and role of energy in their daily lives?In this study, students at Uppsala University, Campus Gotland were interviewed and asked questions about energy and their energy-related attitude and behavior. The data was collected via interviews and then analyzed thematically. The discovered themes varied from students covering the cognitive domain elements to the difference in themes in relation to affective and behavioral domains. Students in general talked about energy in relation to factors that would affect energy behavior and would in turn contribute to saving energy like education. Students also covered various forms of feelings related to energy like anger, fear, and hopefulness. Additionally, various factors showed different patterns when talking about energy-related behavior, energy-saving ivattitudes, and the general perception of the relation between knowing about energy and the attitude and behavior domain. When covering the role of Uppsala University, all students have illustrated the importance of introducing energy-related education to the official curriculum, as well as other methods related to Uppsala University to increase energy knowledge amongst students

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
