No full textEffects of globalization on food production in five European countries
No full textPurpose: The purpose of this paper is to investigate the effects of globalization convergence (GC) and its components (social, economic, political, technological and ecological) on food production (FP). Design/methodology/approach: The methodological approach adopted is based on a quantitative approach, using a static panel data analysis with relevant data from five European countries within five time intervals (2013–2017). Findings: The results indicated that three components of globalization (social, technological and ecological) could significantly contribute to the food industry, while two other components of globalization (economic and political) are negatively correlated with FP. Research limitations/implications: This study contributes to the theoretical recognition of the role of globalization in influencing FP in multidisciplinary interactions. Meanwhile, this study's main limitation lies in the statistical method of panel data analysis, since temporal and spatial changes have not been investigated. Originality/value: Despite the literature on globalization's effect on FP, each globalization component's effect has not been investigated appropriately within cross-countries studies. Hence, the present study addresses a gap in the extant literature by examining the globalization effects on the food industry to promote globalized food security, opportunities and solutions in the study areas
Assessing the role of FinTech in entrepreneurial ecosystems at the international level
Full text linkThe goal of the present research was to assess the role of FinTech progress in the enhancement of entrepreneurial ecosystems at the country level for ten European countries within four-time intervals of 2011, 2014, 2017, and 2021. Thus, the research plan involved an empirical approach that utilized twenty-five and six variables to create the consolidated EE and FinTech indices, respectively. The results revealed significant positive correlations between FinTech (financial and technological dimensions) and EE in all selected countries, exposing the overall effective role of the FinTech index in the EE framework during 2011–2021. This result supported two research hypotheses, revealing that high values of progress in the financial and technological dimensions of FinTech can enhance the EEs in European countries. Additionally, the results revealed the effective role of the FinTech index in the enhancement of EEs through the three enhancing EE elements of “networks”, “demand”, and “intermediate services”, supporting the third research hypothesis. According to our results, the overall status of FinTech in all European countries accelerated from 2011 to 2021. Additionally, the enhancement of the EE in European countries in recent years has transferred from formal and cultural components to technological networks and services. Hence, the technological dimension of FinTech can be defined as a driving power of economic growth in the study area and should be considered in economic programs and revisions of EE structures
Overview of liquid biopsy
No full textNew studies are mainly focused on the new, minimally invasive biomarkers presenting in body fluids as the real-time representative of tumors, entitled “liquid biopsy.” Liquid biopsy contains tumor-derived cells, nucleic acids (DNA, RNA), and tumor vesicles that represent the tumor characteristics. Tumor-derived cells and cells’ contents are subject to complete molecular analysis-mostly unbroken circulating tumor cells (CTCs) and cell-free circulating tumor DNA (cfDNA or ctDNA). Liquid biopsy analysis means the counting and characterization of CTCs, ctDNA/ctRNA, and exosomes to reach the main genetic information of the tumor. Advanced molecular techniques, like next-generation sequencing, droplet digital PCR, cell search, and microfluidic systems, make a comprehensive case for liquid biopsy analyses in a broad range of settings. Initially, the liquid biopsy data was just for the cancer diagnosis, preferably including screenings, but now it is considered for the prediction of response or resistance to the specific medication strategy and personalized medicine. Importantly, the detection of mutations is enabled, which has a high critical impact on making the best therapeutic decisions. The optimized practical setting of liquid biopsy in cancer has not been realized yet, but constant research is focused on establishing innovative liquid biopsy in oncology. In this chapter, we represent liquid biopsy components and summarize the principal techniques and applications of liquid biopsy in urogenital cancer
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
