Martin Luther: music and mission
Authors: Swarbrick John 
Published: July 2020

Abstract
This article seeks to demonstrate Martin Luther's often-overlooked credentials as a musician. Luther was convinced that music was the viva voce evangelii (living voice of the gospel), and unlike other more radical Reformation movements, he encouraged the use of choral and congregational singing in worship. Some of his familiar hymns – Nun freut euch, Ein’ feste Burg and Aus tiefer Not – offer insights into his ambitions to embed congregational singing into his vision of reformed worship, which went hand in hand with liturgical reform. Luther's Formula Missae and the vernacular Deutsche Messe lay the groundwork for Lutheran worship, which restructured the service around the centrality of the gospel proclamation. Luther's musical tradition reached its zenith in the work of J. S. Bach, which continues to echo in the Western musical canon, leaving Luther with a lasting musical legacy.
Domesticating Light: Standards and Artisanal Knowledge in Early Astrophysics
Authors: Ordóñez Javier 
Published: July 2020

Abstract
Astrophysics was born in the nineteenth century as a “New Astronomy” (in the words of Samuel Langley, 1884), a knowledge built primarily by amateurs who explored deep space by studying the Sun, stars and nebulae. They were credible enough to interest physicists who did research on the properties of radiation and hence came to constitute a solid and recognised discipline. The aim of this research is to study the contribution of artisanal knowledge in the construction of this new discipline at two distinct moments. The first, when artisans worked to find a standard to normalise the manufacture of the glass with which the lenses of refracting telescopes were manufactured. The most recognised of these artisans was Fraunhöfer. The second moment occurred when the experience of artisan knowledge enabled the manufacture of instruments that improved the traditional classification of the magnitude of the stars. The search for standards led to an alliance between artisans and scientists during the same period in which spectroscopy was carried out. In this case, a unit of luminous intensity was sought that could serve as a standard to classify the stars by their luminosity. Industries, university laboratories and astronomers interested in solar astronomy (such as Karl F. Zöllner), collaborated with the artisan manufacturers of measuring devices, and gave rise to a paradigmatic case of science and industry transfer.
A New Approach to the Concepts of Conservation to Identify and Evaluate Railway Heritage through Indicators
Authors: Borges Breno Albuquerque B. 
Published: July 2020

Abstract
The wide railway universe, with its particular and peculiar characteristics, requires the implementation of criteria to improve the identification and conservation of cultural goods. Recently concepts of authenticity, integrity and cultural significance have been identified as fundamental in the selection of the cultural heritage of humanity. Although we find these concepts being analyzed in theory as independents, through a theoretical-methodological reflection, this PhD research argues that, in practice, they are interconnected, and therefore should be approached together. Following the contemporary theory of conservation, my doctoral research aims at contributing to the conservation of railways’ heritage using this new approach, by proposing new indicators as assessment tools so that conservation institutions will be able to identify railway goods as cultural heritage. The research uses the Railway Complex of Barreiro, in Portugal, as a case study.
Scientometric Implosion that Leads to Explosion: Case Study of Armenian Journals
Authors: Sargsyan Shushanik , Gzoyan Edita , Mirzoyan Aram , Blaginin Viktor 
Published: July 2020

Abstract

Purpose
The purpose of this study is to introduce a new concept and term into the scientometric discourse and research—scientometric implosion—and test the idea on the example of the Armenian journals. The article argues that the existence of a compressed scientific area in the country makes pressure on the journals and after some time this pressure makes one or several journals explode—break the limited national scientific area and move to the international arena. As soon as one of the local journals breaks through this compressed space and appears at an international level, further explosion happens, which makes the other journals follow the same path.

Design/methodology/approach
Our research is based on three international scientific databases—WoS, Scopus, and RISC CC, from where we have retrieved information about the Armenian journals indexed there and citations received by those journals and one national database—the Armenian Science Citation Index. Armenian Journal Impact Factor (ArmJIF) was calculated for the local Armenian journals based on the general impact factor formula. Journals were classified according to Glänzel and Schubert (2003).

Findings
Our results show that the science policy developed by the scientific authorities of Armenia and the introduction of ArmJIF have made the Armenian journals comply with international standards and resulted in some local journals to break the national scientific territory and be indexed in international scientific databases of RISC, Scopus, and WoS. Apart from complying with technical requirements, the journals start publishing articles also in foreign languages. Although nearly half of the local journals are in the fields of social sciences and humanities, only one journal from that field is indexed in international scientific databases.

Research limitation
One of the limitations of the study is that it was performed on the example of only one state and the second one is that more time passage is needed to firmly evaluate the results. However, the introduction of the concept can inspire other similar case study.

Practical implications
The new term and relevant model offered in the article can practically be used for the development of national journals.

Originality/value
The article proposes a new term and a concept in scientometrics.

Authors: Daraio Cinzia , Bruni Renato , Catalano Giuseppe , Daraio Alessandro , Matteucci Giorgio , Scannapieco Monica , Wagner-Schuster Daniel , Lepori Benedetto 
Published: July 2020

Abstract

Purpose
This paper relates the definition of data quality procedures for knowledge organizations such as Higher Education Institutions. The main purpose is to present the flexible approach developed for monitoring the data quality of the European Tertiary Education Register (ETER) database, illustrating its functioning and highlighting the main challenges that still have to be faced in this domain.

Design/methodology/approach
The proposed data quality methodology is based on two kinds of checks, one to assess the consistency of cross-sectional data and the other to evaluate the stability of multiannual data. This methodology has an operational and empirical orientation. This means that the proposed checks do not assume any theoretical distribution for the determination of the threshold parameters that identify potential outliers, inconsistencies, and errors in the data.

Findings
We show that the proposed cross-sectional checks and multiannual checks are helpful to identify outliers, extreme observations and to detect ontological inconsistencies not described in the available meta-data. For this reason, they may be a useful complement to integrate the processing of the available information.

Research limitations
The coverage of the study is limited to European Higher Education Institutions. The cross-sectional and multiannual checks are not yet completely integrated.

Practical implications
The consideration of the quality of the available data and information is important to enhance data quality-aware empirical investigations, highlighting problems, and areas where to invest for improving the coverage and interoperability of data in future data collection initiatives.

Originality/value
The data-driven quality checks proposed in this paper may be useful as a reference for building and monitoring the data quality of new databases or of existing databases available for other countries or systems characterized by high heterogeneity and complexity of the units of analysis without relying on pre-specified theoretical distributions.
Regional Policy as a Factor in Shaping Regional Development in Poland
Authors: Czaplewski Maciej , Klóska Rafał 
Published: July 2020

Abstract
Regional development is firmly rooted in the theory of land management, and today’s considerations and analyses in this area are gaining special importance. The relationship between specific conditions and the observed effects of regional development was considered under various theoretical concepts. Additionally, the interdependence of processes taking place on the international, national and regional level renders it necessary to pursue, inter alia, an effective regional policy. In this study, particular attention was given to the premises and objectives of intentional actions taken both at supra-regional level (inter-regional policy) and regional level (intra-regional policy). The theoretical considerations concerning the regional policy carried out were supplemented with current statistics regarding the development of regions in Poland. The aim of the study is to show the role of regional policy in shaping regional development and to analyse its current state on the basis of own research using multidimensional comparative analysis (MCA) methods. The considerations presented in the article lead to the conclusion that regional policy is an important factor in regional development, and the presented research results allow to assess the current level and diversity of this development in Poland.
A Question of Value: Exploring Perceptions of Higher Education Value in Academic and Popular Literature
Authors: Saurbier Ann L. 
Published: July 2020

Abstract

Research purpose. The pursuit of higher education has, until recently, been viewed as a worthwhile pursuit. However, factors including rising tuition costs, graduate job-readiness, and the associated debt have diminished the perceived value of college degrees at all levels. This research seeks to explore both academic literature and popular publication sources to gain a deeper understanding of the value proposition of higher education in the dynamic 21st century.

Design/Methodology/Approach. An aggregative qualitative synthesis of the selected academic and popular sources is examined for emergent themes. Drawing on theory from the disciplines of economics, marketing, education and humanities, a meta-matrix is then constructed from the content analysis, with the goal to not only more effectively describe the variant perceptions of value but also to reconcile and synthesizes these views where possible.

Findings. The perceived value of a contemporary higher education has been challenged, requiring post-secondary institutions to find new ways to demonstrate the benefits that accompany an advanced degree. Through a more explicit understanding of the dichotomies that exist between the various perceptions of value, as well as the emergence of thematic agreements, a more holistic depiction of higher education’s value proposition may be created.

Originality/Value/Practical implications. The creation of a framework that allows post-secondary institutions to gain a more explicit understanding of the perceptions of value held both within and outside the academy will allow colleges and universities to respond more directly to this critical challenge and more accurately demonstrate both the short-term and life-long value of a college degree.
Epicardial Fat Volume as a New Imaging-Based Feature Associated with Risk of Recurrence after Pulmonary Veins Ablation in Atrial Fibrillation
Authors: Blîndu Emanuel , Korodi Szilamér , Bordi Lehel , Kovács István , Benedek Imre 
Published: July 2020

Abstract

Background: Atrial fibrillation (AF), a common arrhythmia in clinical practice, is associated with a high rate of complications and an increased risk for thromboembolic events. Pulmonary vein ablation is a new therapeutic option to cure AF; however, it remains associated with a high rate of recurrence. In this study we aimed to identify the clinical characteristics and imaging-based features that may predict the risk of recurrence after pulmonary veins ablation in atrial fibrillation.

Materials and method: Twenty-four patients with paroxysmal and persistent AF, who underwent radiofrequency catheter ablation and a 12-month follow-up were included in the study. Group 1 included 8 patients with AF recurrence, and group 2 included 16 patients with no AF recurrence. In all cases, cardiovascular risk factors, ejection fraction, left atrial diameter, atrial volumes, and epicardial fat volume were analyzed.

Results: CT analysis revealed that patients with AF recurrence presented a significantly larger mean index of left atrial volume (59.57 ± 8.52 mL/m2 vs. 49.99 ± 10.88 mL/m2, p = 0.04), right atrial volume (58.94 ± 8.37 mL/m2 vs. 43.21 ± 6.4 mL/m2, p<0.0001), and indexed bi-atrial volume (118.5 ± 15.82 mL/m2 vs. 93.19 ± 16.42 mL/m2, p = 0.005). At the same time, CT analysis of the epicardial adipose tissue volume indicated that patients with AF recurrence have a larger amount of epicardial fat than those without AF recurrence (176.4 ± 100.8 mL vs. 109.8 ± 40.73 mL, p = 0.02).

Conclusion: Left atrial diameter, indexed atrial volumes, and epicardial fat volume may be used as factors to identify patients at risk for developing recurrence after pulmonary vein ablation.

Authors: Dicu Delia-Roxana , Lazăr Ana Petra , Lazăr Luminița 
Published: July 2020

Abstract

Background: Despite the scarcity of studies regarding periodontal disease in young patients (teenagers and young adults), it seems that this disorder is also affecting the young population. Risk factors for periodontal disease include older age, chronic tobacco use, male gender, habits regarding oral hygiene, educational status, ethnicity, and financial status.

Aim: This study aimed to evaluate the periodontal health among adolescents in two high schools in Târgu Mureș that had dental practices.

Material and Methods: An online questionnaire consisting of 16 questions was distributed among high schoolers of Târgu Mureș. Data about personal characteristics, oral hygiene habits, family history of periodontal disease, risk factors for periodontal disease, and symptoms of periodontal disease observed by the respondents were collected and analyzed.

Results: Out of the 501 teenagers who responded to the online questionnaire, 114 (22.8%) were 18 years old and were mostly females (88.2%). Regarding oral hygiene habits, 75.8% prefer a manual toothbrush over an electric toothbrush, 66.7% brush their teeth twice a day, and 54.1% practice a horizontal method of toothbrushing. Mouthwash was the most used oral hygiene aid (58.3%). Family history of periodontal disease was observed in 21.9% of respondents. As favoring factors, nicotine addiction (23.8%), bruxism (24.4%), interposition of various objects between teeth (48.3%), past or present orthodontic treatments (38.7%) were recorded. Symptoms of gingivitis and periodontitis, such as gingival bleeding (81.4%), redness of gingiva (39.3%), increased gingival volume (44.5%), gingival retraction (22.8%), and halitosis (81%), were present in the responding teenagers.

Conclusions: In this study, periodontal disease was affecting mostly adolescent females who are practicing inappropriate methods of toothbrushing with inadequate frequency.
The Impact of Senior-Managerial Leadership Culture on Value Creation for Shareholders – A Study of Local and Multinational Companies in Portugal
Authors: Romana Fernando Acabado 
Published: July 2020

Abstract

Objective: This study is based on the analysis of three fundamental aspects of company and managerial life: the culture of organizations, the style of leadership and financial performance. Its focus was to question the connection between these and to devise a strategy that could be applied in Portugal, during 2017 and 2019, in industrial sector companies.

Methodology: To do so, it was decided to start methodological analysis of the behaviour of managers and organizations operating in this environment, considering several classifications: multinational companies operating in Portugal and Portuguese companies with a strategy for and in the process of internationalization. On this basis the study problem was set at the level of managerial behaviour, bearing in mind that this varies depending on the type of organization in which managers’ work. The problem involves scientific, methodological, and cultural aspects that have already been demonstrated by several authors, whose considerations have been incorporated. The study was conducted in 16 companies operating in Portugal.

Findings: The characteristics of leadership in the multinationals tend towards greater balance between the four roles of each of the corresponding quadrants, while in the national companies it tends to be more internally focused.

Value Added: This difference could be related to what R. Quinn calls the Normal State of Leadership, which is focused on the comfort zone that the internal processes seem to generate; the multinational companies are more focused on external aspects and future development – Fundamental State of Leadership – centred on strategic dedication to clients and flexibility.

Recommendations: Dedication to clients and flexibility, that we intend to link with Internal Marketing strategy drivers, considering the investigation ideas for this paper, as the demonstration if some different Leadership Styles influence the Financial Performance of the Companies or not.
Estimating Literacy Levels at a Detailed Regional Level: an Application Using Dutch Data
Authors: Bijlsma Ineke , van den Brakel Jan , van der Velden Rolf , Allen Jim 
Published: July 2020

Abstract
Policy measures to combat low literacy are often targeted at municipalities or regions with low levels of literacy. However, current surveys on literacy do not contain enough observations at this level to allow for reliable estimates when using only direct estimation techniques. To provide more reliable results at a detailed regional level, alternative methods must be used.
The aim of this article is to obtain literacy estimates at the municipality level using model-based small area estimation techniques in a hierarchical Bayesian framework. To do so, we link Dutch Labour Force Survey data to the most recent literacy survey available, that of the Programme for the International Assessment of Adult Competencies (PIAAC). We estimate the average literacy score, as well as the percentage of people with a low literacy level. Variance estimators for our small area predictions explicitly account for the imputation uncertainty in the PIAAC estimates. The proposed estimation method improves the precision of the area estimates, making it possible to break down the national figures by municipality.
Controlling for Selection Bias in Social Media Indicators through Official Statistics: a Proposal
Authors: Iacus Stefano M. , Porro Giuseppe , Salini Silvia , Siletti Elena 
Published: July 2020

Abstract
With the increase of social media usage, a huge new source of data has become available. Despite the enthusiasm linked to this revolution, one of the main outstanding criticisms in using these data is selection bias. Indeed, the reference population is unknown. Nevertheless, many studies show evidence that these data constitute a valuable source because they are more timely and possess higher space granularity. We propose to adjust statistics based on Twitter data by anchoring them to reliable official statistics through a weighted, space-time, small area estimation model. As a by-product, the proposed method also stabilizes the social media indicators, which is a welcome property required for official statistics. The method can be adapted anytime official statistics exists at the proper level of granularity and for which social media usage within the population is known. As an example, we adjust a subjective well-being indicator of “working conditions” in Italy, and combine it with relevant official statistics. The weights depend on broadband coverage and the Twitter rate at province level, while the analysis is performed at regional level. The resulting statistics are then compared with survey statistics on the “quality of job” at macro-economic regional level, showing evidence of similar paths.
On Accuracy Estimation Using Parametric Bootstrap in small Area Prediction Problems
Authors: Żądło Tomasz 
Published: July 2020

Abstract
We consider longitudinal data and the problem of prediction of subpopulation (domain) characteristics that can be written as a linear combination of the variable of interest, including cases of small or zero sample sizes in the domain and time period of interest. We consider the empirical version of the predictor proposed by Royall (1976) showing that it is a generalization of the empirical version of the predictor presented by Henderson (1950). We propose a parametric bootstrap MSE estimator of the predictor. We prove its asymptotic unbiasedness and derive the order of its bias. Considerations are supported by Monte Carlo simulation analyses to compare its accuracy (not only the bias) with other MSE estimators, including jackknife and weighted jackknife MSE estimators that we adapt for the considered predictor.
In-house validation method for quantification of amoxicillin in medicated feedingstuffs with the use of HPLC-DAD technique
Authors: Patyra Ewelina , Kwiatek Krzysztof 
Published: July 2020

Abstract

Introduction
A high-performance liquid chromatographic–diode array detector (HPLC-DAD) method for the determination of amoxicillin in medicated feedingstuffs was developed and validated. The method was used to investigate the quality requirements of animal feedingstuffs (declared content of active substance and feed homogeneity).

Material and Methods
Two-gram samples were extracted by potassium phosphate buffer solution. Extracts were filtered and directly analysed by HPLC-DAD without further clean-up. Amoxicillin was separated by acetonitrile and 0.01M phosphate buffer (pH 5.0) on a Phenomenex Luna C18 column.

Results
This method provided average recoveries of 76.1 to 81.6% with coefficients of variation (CV, %) for repeatability and reproducibility in the ranges of 3.7–7.2% and 5.3–7.6%, respectively. The limit of detection was 51.2 mg/kg and limit of quantification was 103.0 mg/kg.

Conclusion
The method was successfully validated and proved to be efficient, precise, and useful for quantification of amoxicillin in medicated feedingstuffs.

Published: July 2020

Abstract
Innovation and knowledge-intensive economy are considered crucial for addressing challenges and opportunities currently faced by Europe. The present paper aims to provide inputs for building a long-term vision aiming to promote innovation and knowledge economy for fostering smart, sustainable and inclusive growth. We analyze microdata from the 2016 Innobarometer “EU Business Innovation Trends” (Flash Eurobarometer 433), covering 14,112 companies from 30 countries in order to shed light on main drivers and results of business investments in innovation. We focus our analysis on high-tech industries and knowledge-intensive services. Additionally, expected positive impacts of innovation in knowledge-intensive sectors are explored in terms of job creation, digital economy, environment protection, health, transport, food quantity and quality, development of smart cities, etc. Our results are useful for designing an improved support for the emergence and impact of knowledge-intensive economy.
