Abstract
The European Regional Focal Point for Animal Genetic Resources (ERFP), is the European regional platform of National Coordinators (NCs) supporting management of animal genetic resources (AnGR). To assess the performance of the ERFP platform/network and consider options for its further development, a survey was performed among NCs. Twenty-five NCs responded to the survey on the roles, values and future of the platform. The paper provides an analysis of the results of the survey, including a ERFP SWOT analysis. NCs indicated high value of the support of the ERFP in fulfilling their functions at the national level. They highlighted the well-established network and facilitated communication and collaboration among NCs and other AnGR experts in Europe. The NCs appreciated the efficient organizational structure of the ERFP (Working Groups, Task Forces, Ad hoc Actions), and the well-functioning Secretariat. Indicated weak points included discontinuity of NC positions in some countries, and low levels of activities in some countries. NCs saw new opportunities for ERFP development in the context of the EU policy and regulatory framework related to AnGR management, and in strengthening the role of the Secretariat. No immediate threats were identified, however potential future threats included insufficient financing and lack of continuity. The NCs highly appreciated the substantial progress achieved by the ERFP over the last 20 years.
On the metric dimension of a total graph of non-zero annihilating ideals
Authors: Abachi Nazi , Sahebi Shervin 
Published: January 2021

Abstract
Let R be a commutative ring with identity which is not an integral domain. An ideal I of a ring R is called an annihilating ideal if there exists r ∈ R − {0} such that Ir = (0). Visweswaran and H. D. Patel associated a graph with the set of all non-zero annihilating ideals of R, denoted by Ω(R) as the graph with the vertex-set A(R)*, the set of all non-zero annihilating ideals of R and two distinct vertices I, J are joined if and only if I +J is also an annihilating ideal of R. In this paper, we study the metric dimension of Ω(R) and provide metric dimension formulas for Ω(R).

Published: January 2021

Abstract
Let G = (V (G), E(G)) be a connected graph and x, y ∈ V (G), d(x, y) = min{ length of x − y path } and for e ∈ E(G), d(x, e) = min{d(x, a), d(x, b)}, where e = ab. A vertex x distinguishes two edges e
1 and e
2, if d(e
1, x) ≠ d(e
2, x). Let WE
= {w
1, w
2, . . ., wk
} be an ordered set in V (G) and let e ∈ E(G). The representation r(e | WE
) of e with respect to WE
is the k-tuple (d(e, w
1), d(e, w
2), . . ., d(e, wk
)). If distinct edges of G have distinct representation with respect to WE
, then WE
is called an edge metric generator for G. An edge metric generator of minimum cardinality is an edge metric basis for G, and its cardinality is called edge metric dimension of G, denoted by edim(G). The circulant graph Cn
(1, m) has vertex set {v
1, v
2, . . ., vn
} and edge set {vivi

+1 : 1 ≤ i ≤ n−1}∪{vnv
1}∪{vivi+m
: 1 ≤ i ≤ n−m}∪{vn−m+ivi
: 1 ≤ i ≤ m}. In this paper, it is shown that the edge metric dimension of circulant graphs Cn
(1, 2) and Cn
(1, 3) is constant.

Published: January 2021

Abstract
In this paper, we define the Pell-Pell p-sequence and then we discuss the connection of the Pell-Pell p-sequence with Pell and Pell p-sequences. Also, we provide a new Binet formula and a new combinatorial representation of the Pell-Pell p-numbers by the aid of the nth power of the generating matrix the Pell-Pell p-sequence. Furthermore, we obtain an exponential representation of the Pell-Pell p-numbers and we develop relationships between the Pell-Pell p-numbers and their permanent, determinant and sums of certain matrices.

Fabrication and Characterization of Fibrous Polycaprolactone Blended with Natural Green Tea Extracts Using Dual Solvent Systems
Authors: Mohd Rashid Ainatul Aqilah Binti , Jaganathan Saravana Kumar , Mohd Khudzari Ahmad Zahran , Ismail Ahmad Fauzi 
Published: January 2021

Abstract
Nanofibrous dressings serve as an impeccable candidate in the management of wounds. Nanofibrous composites composed of polycaprolactone (PCL) and green tea using dual solvent systems at different ratios were fabricated through electrospinning. Pure PCL electrospun fibers along with composites were characterized by using scanning electron microscopy (SEM), wettability, water uptake analysis, and Fourier transform infrared spectroscopy (FTIR). SEM indicated that fibrous morphology and the diameter of PCL/green tea were smaller for chloroform/dimethylformamide (DMF) (601 nm) and acetone/DMF (896 nm) than the pure PCL (673 nm and 1,104 nm for chloroform/DMF and acetone/DMF, respectively). Wettability of the fabricated composites was increased, and pure PCL fibers were slightly more hydrophobic (100°) than PCL/green tea (94°). Water uptake of the composites was enhanced compared with PCL significantly in acetone/DMF. The PCL/green tea nanofibrous wound dressing with enhanced physicochemical properties serves as an indispensable candidate for wound healing applications.
Defining the effective deformation of the vertebral column
Authors: Daghighi Abtin , Tropp Hans 
Published: January 2021

Summary
The Cobb angle is calculated in the coronal plane, irrespective of vertebral rotation, lordokyphosis and local wedge properties of individual verte-brae other than the end plates used for the measurement. Rigorous three-dimensional generalizations of the Cobb angle are complicated for at least two reasons. Firstly, the vertebral column is segmented, not continuous, making the choice of rigorous model ambiguous. Secondly, there exists an inherent curvature (in terms of thoracic kyphosis and lumbar lordosis) that may be considered physiologically healthy or ’normal’. When attempting to find a three-dimensional deviation measure, such normal sagittal curvature must be compensated for.
In this paper we introduce a three-dimensional local deformation parameter (which we call the local effective deformation) motivated by both biomechanics and the basic theory of spatial curves, and simultaneously introduce a technical procedure to estimate the parameter from CT scans using MPR (multi-phase reconstruction) in PACS (IDS-7). A detailed description of the proposed modelling of vertebral column deformation is given, together with a stepwise procedure to estimate the three-dimensional deformation (in terms of local effective deformation). As a deformation measure it requires knowledge about the natural healthy kypholordosis. A method is described by which such knowledge may be incorporated in future work.
Variation in Growth Response of Coastal Dune-Building Grass Species Ammophila Arenaria and Leymus Arenarius to Sand Burial
Authors: Ievinsh Gederts , Andersone-Ozola Una 
Published: January 2021

AbstractAmmophila arenaria and Leymus arenarius are dune-building grass species native to European seacoasts. The present study aimed to compare growth responses to the sand burial of A. arenaria and L. arenarius from coastal habitats of the Baltic Sea, when the intensity of sand accretion was relatively low under controlled conditions. Plants were grown from seeds collected from natural coastal habitats, transplanted into individual containers, buried in the sand at different depths in the rapid shoot elongation stage, and further cultivated (11 or 9 weeks) in an automated greenhouse. Burial in sand significantly stimulated the growth of shoots of A. arenaria, the effect was earlier at high burial intensities (46 and 60%) and was evident ten days after the start of treatment. Both shoot and root dry mass increased for plants buried at 13%; however, increased burial depth (37, 46 and 60%) resulted in a significant increase in root biomass. In comparison, shoot biomass decreased significantly at the highest burial intensity (60%). For L. arenarius, there was no direct dependence of shoot elongation rate on burial depth. There was a tendency for increased elongation growth and biomass allocation to leaf sheaths despite a decrease in total shoot mass. Most strikingly, root biomass decreased with sand burial in parallel with increased burial depth up to 21% intensity. In conclusion, although both grass species showed a positive shoot growth response to moderate sand burial intensity, differences in individual responses at the morphological and physiological level indicate the existence of different genetically based adaptation strategies.
Pandemic and Public Service Media: Lessons from Finland
Authors: Horowitz Minna Aslama , Leino Ritva 
Published: January 2021

Abstract
This essay discusses the global context of public communication during COVID-19, as well as some specific lessons learned from public service media (PSM), specifically from the Finnish Broadcasting Company (Yleisradio, Yle). We address the role of PSM as a national information channel during crises and as a sustainable element in the media system, points to the need to understand its role beyond news and to develop new interactive alternatives to global platforms, and calls for PSM organisations to address its audience – not as consumers – but as people with needs for information, entertainment, learning and meaningful interactions.
Distributor Strategies in the Face of Closed Cinemas: Norwegian Responses to Covid-19
Authors: Øfsti Marius 
Published: January 2021

Abstract
This article examines the choices made by Norwegian distribution companies during three key phases of cinema lockdown and reopening in 2020. Though the article mainly aims to chronicle this particular moment in time I find that Norwegian and Scandinavian VOD-services acted differently than international services and that, while distributor companies used several different strategies in the face of sudden change, no one was close to recouping the losses from the lack of ordinary cinematic exhibition.

The World in Children’s Minds – or Sustainable Entrepreneurship Education as Empowerment to Shape a Desirable Future
Authors: Schmidt-Hönig Kerstin , Pröbstl Gerlinde 
Published: January 2021

Abstract
How can we succeed in meeting the challenges of the future world in the best possible way? In order to support children in their development into optimistic, self-effective adults, it is necessary to find out how children perceive their world and how they combine these perceptions with their cognitive knowledge. This article examines the question of what children’s ideas about the world look like in children at the end of primary school, or what information is included in them. In a pilot study, mental maps were used to visualize the child’s world view. Accompanying questions were used to ascertain the children’s knowledge of current global problems. The focus was on the students’ thematic interests, which accompanied the discussions with the pupils. Already the first evaluations of the Mental Maps, which were made by the students, allow conclusions to be drawn. There is no uniform level in the children’s cognitive maps with regards to the concrete positional relationship of spatial units, e.g. continents and oceans. The statements about the content details of these maps are shaped by the children’s perception. The Mental Maps show a combination of indirect, direct and emotional spatial perception. The awareness of the pupils regarding global challenges, oriented towards the Sustainable Development Goals, proves to be clearly pronounced in the impulse-based interviews in the 4th grade. Thus, the pilot study allows the conclusion that already at the end of primary school pupils develop an awareness of global challenges and the ability to act. The SDGs of the UN Agenda 2030 offer a suitable basis for this. In addition to the development of a worldwide rough topographical orientation grid, the aim is to give children an understanding of global connections and to educate them to become global citizens of the future world.
Critical Entrepreneurship Education in General Education and TVET: Two Concepts of Practice in a South African Township
Authors: Forcher-Mayr Matthias , Mahlknecht Sabine 
Published: January 2021

Abstract
This paper examines the dominant approach to entrepreneurship education in the South African education system regarding the crisis of youth unemployment. It draws on the case of the public-school sector, in conjunction with the technical vocational education and training (TVET) subsector of the post-school education sector. The comparison of the entrepreneurship education sector plan for public schools with the discourse on TVET reform shows that entrepreneurship education similarly follows the čskills perspective’ with a dominant focus on the formal economy, which is informed by a human-capital based and productivist approach to education. The authors argue that this understanding of entrepreneurship education employs a too narrow perspective on youth unemployment as it overlooks individual capabilities and agency and can contribute to an experience of youth unemployment as individual failure. The authors expand this argument by suggesting a critical entrepreneurship education approach, which is outlined based on two programmes at primary-school and post-school education (TVET) level in a poor urban area. The authors argue that a critical entrepreneurship education approach contributes to learning for capabilities, social justice and democratic citizenship.

Friction Stir Welding joint quality depends on input parameters such as tool rotational speed, tool traverse speed, tool tilt angle and an axial force. Surface defects formation occurs when these input parameters are not selected properly. The main objective of the recent paper is to develop Discrete Wavelet Transform algorithm by using Python programming and further subject it to the Friction Stir Welded samples for the identification of various external surface defects present.
Fusing Multi-Attribute Decision Models for Decision Making to Achieve Optimal Product Design
Authors: Olabanji Olayinka Mohammed , Mpofu Khumbulani 
Published: January 2021

Abstract
Manufacturers need to select the best design from alternative design concepts in order to meet up with the demand of customers and have a larger share of the competitive market that is flooded with multifarious designs. Evaluation of conceptual design alternatives can be modelled as a Multi-Criteria Decision Making (MCDM) process because it includes conflicting design features with different sub features. Hybridization of Multi Attribute Decision Making (MADM) models has been applied in various field of management, science and engineering in order to have a robust decision-making process but the extension of these hybridized MADM models to decision making in engineering design still requires attention. In this article, an integrated MADM model comprising of Fuzzy Analytic Hierarchy Process (FAHP), Fuzzy Pugh Matrix and Fuzzy VIKOR was developed and applied to evaluate conceptual designs of liquid spraying machine. The fuzzy AHP was used to determine weights of the design features and sub features by virtue of its fuzzified comparison matrix and synthetic extent evaluation. The fuzzy Pugh matrix provides a methodical structure for determining performance using all the design alternatives as basis and obtaining aggregates for the designs using the weights of the sub features. The fuzzy VIKOR generates the decision matrix from the aggregates of the fuzzified Pugh matrices and determine the best design concept from the defuzzified performance index. At the end, the optimal design concept is determined for the liquid spraying machine.
Anxiety and depression symptoms among ovarian cancer patients in China: a cross-sectional study†
Authors: Chen Jing , Long De-Rong , Guo Xiu-Jing , Liu Yi , You Hua-Xuan 
Published: January 2021

Abstract

Objective
To investigate the prevalence of cancer-related depression and anxiety in western China among patients with ovarian cancer and analyze their influencing factors.

Methods
In this prospective cross-sectional study, qualified patients were asked to fill in questionnaires. Multivariate analysis and binary logistic regression analysis were used to test the associations among symptoms of depression and anxiety, coping styles, and influencing factors.

Results
A total of 270 ovarian cancer inpatients who met the criteria for participation in the study completed the questionnaires. The levels of depression and anxiety that prevailed in ovarian cancer patients were 47.03% and 57.77%, respectively. Among them, 90.38% of cancer-related anxiety patients and 91.33% of cancer-related depression patients showed mild symptoms. The chi-square test showed that there were statistically significant differences (P < 0.05) in the fields of education level and income. T-test showed that cancer-related depression and anxiety were associated with coping style, and the difference had statistical significance (P < 0.05). Furthermore, multivariate analysis showed that the education level and coping style were the independent influencing factors of depression and anxiety.

Conclusions
The present study suggested that about half of the ovarian cancer patients had with depression and anxiety symptoms. The majority of the cancer-related depression and symptoms were mild. Educational level and coping style should be considered during the interventions of cancer-related depression and anxiety.
Ludwik Fleck, Alfred Schutz, and Trust in Science: The Public Responsibility of Science Education in Challenging Times
Authors: Olesko Kathryn M. 
Published: January 2021

Abstract
Ludwik Fleck and Alfred Schutz each wrote groundbreaking treatises in the 1930s that laid the foundation for their views on the role of science education in establishing trust in science. This essay examines how science education was for Fleck explicitly and for Schutz implicitly a crucial site for understanding the social dimensions of knowledge, for understanding how layers of knowledge are socially distributed among groups, and for conceptualizing how different cognitive groups, from experts to laypersons—communicate with one another in a democratic exchange of information. Their vision of the role of science education in establishing trust is particularly appropriate for addressing contemporary challenges to science and its results.
Similarities, Differences, and Missed Connections between Thomas S. Kuhn, Gaston Bachelard and the Continental Historiography of Science
Authors: Fragio Alberto 
Published: January 2021

Abstract
According to the American philosopher, Michael Friedman, while triggering the so-called “historical turn,” Kuhn reinstated the history of science as perhaps the most important object for the philosophy of science. In this paper, I show that this reinstatement is rather a rehabilitation of the philosophical and epistemological uses of the history of science, something already present in the continental historiography of science in the first half of the twentieth century, and especially in Gaston Bachelard’s work. In this sense, I undertake a review of the European history and philosophy of science during that period, paying special attention to Gaston Bachelard as one of the leading representatives of the French historical epistemology of the 1930s. I conclude with the late and quite problematic reception of Bachelard’s thought in the early work of Thomas S. Kuhn. My thesis is this strand may help to outline what is continental history and philosophy of science.

Sentential operators – their interaction (with vectors of time, causality and epistemic relevance) and their constructions
Authors: Gahér František 
Published: January 2021

Abstract
The paper starts by briefly describing the so‐called truth‐functional approach to sentential operators, typical to logic, as opposed to the more multi‐faceted approach of linguistics. The latter reflects the more complex, substantial relations between the contents of utterances, emphasizing the logico‐semantical relations and functions of sentential operators. However, as an alternative to the pragmatically inclined critique of the truth‐functional approach, the paper proposes two possible directions of explaining the specific content of sentential operators by virtue of which they transcend the role of mere truth functions. Firstly, the paper summarizes our previous investigations into the interactions between sentential operators and (1) the vector of the course of events described by a compound sentence, and (2) the direction of grammatical time captured by a compound sentence. The paper focuses on how this interaction is coordinated with the particular epistemic goal (prediction, explanation etc.) pursued when using the meaning of a complex sentence. Using the concepts of necessary and sufficient conditions, and by characterizing the vectors of condition (the if‐vector), time and relevance (dominance or the epistemic vector), the paper demarcates the rules of correspondence for conditional operators as cases of combinatorics, as described by some linguists. Secondly, based on a distinction between different constructions the same operators as truth‐functions, the paper provides a logico‐semantical explanation of the specific meaning of the else, unless and although connectives, traditionally discussed by linguists. We believe that the extensions proposed here move the camp defending a logico‐semantic approach to sentential operators at least somewhat closer to the camp of linguistic investigation.
