Exploitation of microbial activities at low pH to enhance planetary health
Full text linkAwareness is growing that human health cannot be considered in isolation but is inextricably woven with the health of the environment in which we live. It is however under-recognised that the sustainability of human activities strongly relies on preserving the equilibrium of the microbial communities living in/on/around us. Microbial metabolic activities are instrumental for production, functionalization, processing and preservation of food. For circular economy, microbial metabolism would be exploited to produce building blocks for the chemical industry, to achieve effective crop protection, agri-food waste revalorization or biofuel production, as well as in bioremediation and bioaugmentation of contaminated areas. Low pH is undoubtedly a key physical-chemical parameter that needs to be considered for exploiting the powerful microbial metabolic arsenal. Deviation from optimal pH conditions has profound effects on shaping the microbial communities responsible for carrying out essential processes. Furthermore, novel strategies to combat contaminations and infections by pathogens rely on microbial-derived acidic molecules that suppress/inhibit their growth. Herein, we present the state-of-the-art of the knowledge on the impact of acidic pH in many applied areas and how this knowledge can guide us to use the immense arsenal of microbial metabolic activities for their more impactful exploitation in a Planetary Health perspective.Published version: [https://technorep.tmf.bg.ac.rs/handle/123456789/7347]This is the peer-reviewed version of the following article: Atasoy Merve, Álvarez Ordóñez Avelino, Cenian Adam, Đukić-Vuković Aleksandra, Lund Peter A, Ozogul Fatih, Trček Janja, Ziv Carmit, De Biase Daniela.

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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Preface
No full textPreface
We are delighted by the fact that we can publish the next issue of our journal despite the pandemic and related issues. This combined volume 3 and 4 is devoted to contributions from the VII Baltic Forum of Biogas and Circular Economy, to papers stimulated by BSR projects LowTemp, ActNOW!, Wasteman as well as to other results proposed by various authors during these two difficult years 2020 and 2021. The published papers deal with environmental issues relating to air pollution, building thermo-modernisation and ventilation and eco-energetics, understood in the context of knowledge concerning the sustainable generation of heat and power.
When considering sustainable energetics, we have in mind its reliance on renewable sources, its increasing efficiency (hence distributed energetics and using where appropriate co- or polygeneration) and reducing the use of all fossil fuels (both as energy resources and those needed for agricultural and other purposes). Another aspect of sustainability is biodiversity — the inverse of the monoculture. Nowadays, much attention is being directed towards concepts of biorefineries and the circular economy, i.e. an integrated approach along with higher recovery rates; issues such as a transition from waste organic residues into marketable products — applying new technological solutions to close the nutrient and carbon cycles. Also the new approach towards utilisation of waste polyolefins is highly recommended, in order to reduce plastic pollution of our oceans, at the same time recovering their value as raw material. Alongside the above, current and future market applications of microalgae and hydrogen production from biowaste are topics of high importance.
When we speak of sustainable energetics, we also emphasize its social (including food security as well as the preservation of cultural goods) and economic aspects (including the influence of bioenergy on the labour market and energy security). According to the current state of knowledge, the development of local, distributed energetics seems to be a very effective way to utilise renewable energy sources, stimulating economic development of regions and increasing energy safety. Also important is that sustainability chimes with the contemporary agenda, with its prosumer (civic) character, drawing attention to the socio-economics of heat and power generation. The once passive energy consumer, voiceless and dependent on large often monopolistic corporations, becomes a partner — an energy co-producer. This extends the scope of their freedom in civil society, as well as enables them to participate in the distribution of various subsidies (in Poland represented, among others, through a system of certificates).Preface
