A Procedure for Estimating the Variance of the Population Mean in Rejective Sampling
Authors: Stefan Marius , Hidiroglou Michael A. 
Published: March 2020

Abstract
Rejective sampling was first introduced by Hájek in 1964 as a way to select a sample consisting uniquely of distinct units. If n denotes the fixed sample size, the n units are drawn independently with probabilities that may vary from unit to unit and the samples in which all units are not distinct are rejected. More generally, in rejective sampling, we select repeated samples according to a basic sampling design until a selected sample meets a specified balancing tolerance. Given a set of auxiliary variables, we consider a procedure in which the probability sample is rejected unless the sample mean of the auxiliary variables is within a specified distance of its corresponding population mean. The procedure represents an alternative to the well-known balanced cube method. In this article, we propose an estimator of the variance under the rejective sampling design. We also present the results of a Monte Carlo simulation study.

Abstract
It is a well-known fact that research and development (R&D) activities are an important factor in maintaining a business on the market. Nowadays, not only is conducting R&D crucial for entities from new technology sector, but also for companies from each sector, including service entities. The aim of the study was to investigate R&D activities among the biggest publicly traded entities in Poland and to examine the way economists and engineers understand the notion of R&D. We hypothesize and find that R&D expenditure is underestimated or unrecognized in financial reports disclosed by service sector enterprises. Further, we surveyed professional economists and engineers to investigate their knowledge about R&D notion and ability to distinguish operational (day-to-day) actions from R&D activities. The study results indicated difference between the opinions expressed by economists and engineers. Our findings are important for regulators and practitioners as they pinpoint that a substantial change in the definition of R&D is required in order to facilitate a wider adoption of R&D by companies rendering services.
Improvement of IT Infrastructure Management by Using Configuration Management and Maturity Models: A Systematic Literature Review and a Critical Analysis
Authors: Serrano João P. , Pereira Rúben F. 
Published: March 2020

Abstract

Background and purpose: This research aims to investigate which benefits one may expect using Maturity Models in Configuration Management (CM) domain. CM is a support process that helps organizations have better management of their infrastructure. Its importance, in the Information Technology (IT) domain, has increased in recent years, despite this process not being technologically new, and the fact that many organizations implement this process in a haphazard way, which results in it not producing the benefits that it should produce. With the intention of assessing and improving the organizations’ IT processes practices and capabilities, MMs have been developed and implemented. However, the application of MM in the CM domain is yet to be explored.

Design/Methodology/Approach: Two Systematic Literature Reviews (SLRs) and a Critical Analysis were performed. In sum, 80 scientific articles of the most rated conferences and scientific journals were analyzed and conclusions were drawn.

Results: This research concludes that despite the CM process being badly implemented, using a MM this process could decrease operational costs and increase the quality management of the infrastructure.

Conclusion: However, no MM has been developed so far for the CM process practices. This MM would be a viable support tool for the IT organizations providers since this would help organizations have a mature CM process and better control of their IT infrastructure. Therefore, the existence of a MM for the CM domain would be a welcome advancement that should be developed in the future.
Association between Field of Work, Years of Service, and Sickness Absenteeism in Public Administration
Authors: Buzeti Jernej 
Published: March 2020

Abstract

Background and Purpose: Statistics of sickness absenteeism in public administration in Slovenia is considerably higher (7.1% in 2018) than the percentage that applies for the whole of Slovenia (4.5% in 2018). The data also shows a similar pattern in the public sector in other countries. According to that, the main purpose of our research is to investigate the connection between fields of work, years of service, and sickness absenteeism in public administration in Slovenia.

Methodology: Research data was collected with the help of an online questionnaire, which was designed for empirical research and consisted of several sets of questions. The collected data was processed using the SPSS statistical program.

Results: The research was conducted in 2015 in public administration institutions, and 3,220 employees from public administration were included in our research sample. The results of the research show that there is a statistically significant connection between sickness absenteeism in public administration and years of service and the field of work of employees in public administration.

Conclusion: The survey helps us to understand the connection between sickness absenteeism and years of service and field of work of employees in public administration. With regard to the results, it would be reasonable to adopt measures focused on groups of employees in public administration (older employees with a greater length of service, employed officials and professional-technical public employees) where sickness absence may be reduced. Sickness absenteeism in these groups of employees could be reduced by providing employees better leadership and conditions for satisfaction in the workplace.

Abstract

Background and Purpose: The aim of the study is to develop a conceptual key competency model for smart factories in production processes, focused on the automotive industry, as innovation and continuous development in this industry are at the forefront and represent the key to its long-term success.

Methodology: For the purpose of the research, we used a semi-structured interview as a method of data collection. Participants were segmented into three homogeneous groups, which are industry experts, university professors and secondary education teachers, and government experts. In order to analyse the qualitative data, we used the method of content analysis.

Results: Based on the analysis of the data collected by structured interviews, we identified the key competencies that workers in smart factories in the automotive industry will need. The key competencies are technical skills, ICT skills, innovation and creativity, openness to learning, ability to accept and adapt to change, and various soft skills.

Conclusion: Our research provides insights for managers working in organisations that are transformed by Industry 4.0. For instance, human resource managers can use our results to study what competencies potential candidates need to perform well on the job, particularly in regards to planning future job profiles in regards related to production processes. Moreover, they can design competency models in a way that is coherent with the trends of Industry 4.0. Educational policy makers should design curricula that develop mentioned competencies. In the future, the results presented here can be compared and contrasted with findings obtained by applying other empirical methods.

Abstract
Yerba mate is a source of biologically active substances. The aim was to determine whether the place of origin of Yerba and the brewing method have any influence on the levels of Ca, Mg and Fe and antioxidant activity of infusions. Samples were steeped in cold water (25°C) and hot water (three consecutive infusions with 85°C water). Infusions had a high antioxidant activity and high Mg level. The levels of elements and the antioxidant activity were influenced by the brewing method. There were no significant differences in the examined parameters depending on the country of origin. The results on the levels of elements and the antioxidant activity indicate that the most efficient brewing method was infusion in hot water. The highest levels of elements were found in first infusions, with the highest antioxidant activity in the third infusions.

Impact of natural antioxidant systems on the oxidation resistance and mechanical properties of polypropylene
Authors: Musajan Dilhumar , Mamatjan Maklinur , Beken Riza , Yimit Mamatjan 
Published: March 2020

Abstract
This paper describes the separation of oxidation resistant components from the seeds of pomegranate (PSA), grape (GSE) and sea buckthorn (SSE). The anti-oxidation properties of the resultant extracts, used as the natural anti-oxidants for polypropylene (PP), were compared with Irganox1010. The effects of these natural antioxidants on the antioxidant levels of PP samples were estimated by thermal oxidative aging and micromixed rheology, OIT, XRD, SEM, TEM and mechanical properties tests of samples before and after aging. The results show that adding PSA, GSE and SSE can obviously increase the mechanical properties of PP. In addition, the molding stability of polypropylene raw material is prolonged and improved. Moreover, the mechanical properties of the PP samples after 240 h of thermal oxidative aging indicates that, the best results, closest to the anti-oxidation ability of Irganox1010, can be obtained when the additive amount is 0.5% (wt%) for PSE or 0.7% (wt%) for GSE.

Published: March 2020

Abstract

Background
Asbestos exposure is associated with increased risk of several diseases, including malignant mesothelioma (MM). Cell surface glycoprotein mesothelin is overexpressed in MM and serum soluble mesothelin-related peptides (SMRP) were already proposed as a diagnostic or prognostic biomarker in MM. However, interindividual variability in serum SMRP levels limits the clinical usefulness. Our primary objective was to investigate the influence of MSLN rs1057147 on serum SMRP levels in asbestos-exposed subjects and patients with asbestos-related diseases as well as on survival in MM.

Subjects and methods
Among 782 asbestos-exposed subjects and patients with asbestos-related diseases, 154 had MM. Serum SMRP levels were determined using sandwich enzyme-linked immunosorbent assay. All subjects were genotyped for MSLN rs1057147 polymorphism using competitive allele-specific polymerase chain reaction. Nonparametric tests, logistic and Cox regression were used in statistical analysis to compare different subject groups.

Results
MM patients had significantly higher SMRP levels than all other subjects (p < 0.001). Compared to wild-type MSLN rs1057147 genotype, both heterozygotes and carriers of two polymorphic alleles had significantly higher SMRP levels among subjects without MM (p < 0.001), but not in MM patients (p = 0.424). If genotype information was included, specificity of SMRP increased from 88.5% to 92.7% for the optimal cutoff value. Overall survival was significantly shorter in MM patients carrying at least one polymorphic rs1057147 allele (HR = 1.72, 95% CI = 1.15-2.55, p = 0.008).

Conclusions

MSLN genetic variability affects serum SMRP levels and was associated with shorter survival of MM patients. Combination of genetic and serum factors could therefore serve as a better diagnostic or prognostic biomarker in MM patients.

Authors: Gocer Gulsen Pinar Soydemir , Ozer Elif Eda 
Published: March 2020

Abstract

Background
There are certain risks of radiotherapy (RT), especially patients with left-sided breast cancer have a higher tendency to develop cardiac complications than the right-sided cancers. This study aims to perform a dosi-metric analysis the effect of RT on coronary arteries and heart in breast-conserving surgery.

Patients and methods
A total of 40 patients with early stage right and left-sided breast carcinomas (T1/T2 + N0) were randomly selected. RT was delivered to the entire breast, and tumor beds were boosted in these patients using tangential fields with computed tomography based planning. The doses for Left anterior descending coronary artery (LAD), left circumflex coronary artery (LCx), right ventricle (RV), left ventricle (LV), and heart were recorded and median values compared between groups.

Results
The highest mean of radiation dose in patients with left-sided breast cancer was to LAD 2402.48 ± 838.39 cGy, while the highest mean dose in right-sided breast cancer patients was to RV 130.18 ± 24.92. The highest maximum dose of radiotherapy was applied to heart at left-sided breast cancer patients as well as at right-sides prients. The mean V5 of the LV was 18.68% (6.89–31.69), mean V25 of the LV was 5.22% (0.45–16.54), mean V5 in bilateral ventricles was 23.73% (2.56–26.89), and mean V25 in bilateral ventricles 6.78% (0.63–13.63).

Conclusions
Especially in left-sided breast cancer, the most direct and best strategy to reduce and protect radiation-induced cardiac injury is to balance dose constraints between several high-dose regions of cardiac substructures and the mean heart dose.
Political Science in The Age of Resentment
Authors: Kazarinova D. B. 
Published: March 2020

Review of the book «Modern political science: Methodology» ed. by O. V. Gaman-Golutvina and A. I. Nikitin, Moscow, Aspect Press, 2019.The article examines some of the resentment related issues of modern politics, using a number of methodological approaches (identitarian approach, constructivist institutionalism, cultural and civilizational approaches, psychological-political and elitist, as well as gender approaches), described in the collective work of the Russian renowned academics "Modern political science: Methodology". These are the cleavages between traditional politics vs post- and pseudo-politics (shift from the normal politics made by consolidating broad strata to self-centered, exclusive, and increasingly differentiated and closed groups of pseudo-policies), conventional political leadership vs populism and anti-elitism (the rapid growth of populists on a global scale, the spread of anti-establishment sentiment, "populism of power" and the crisis of responsible leadership), formal and informal institutions vs personification of politics (reducing the role of institutions and increasing the importance of the human factor ), socio-economic basis of policy vs socio-cultural basis (emphasis on ethnic, religious and gender factors). The resentment as both the cause and effect of identity politics, is a result of an unfair distribution of goods and evils of globalization, or the manifestation of accumulated negative emotions and unjustified expectations. It generalizes these trends and issues and requires new research approaches, since traditional rationalistic approaches based on the theory of rational choice become less effective. To meet the challenges of resentment era, political science should keep balance between rationalism and reflexivity. This balance provides a single epistemological basis for the study of current political reality. It has been successfully reached by the authors of the book "Modern political science: Methodology". The book posits the idea of the fundamental irreducibility of methodology to the sum of the methods. In this regard the volume differs from similar publications aiming to present a wide scope of political methodology. The logic of the representation used by the editors is moving from general to particular, from societal to human, from global to local. The book demonstrates the wide diversity of methodological approaches and the rejection of the ideas of universalism, which adequately characterizes the state of Russian political science. The work is remarkable because it not only reflects, but also structures the Russian political science.
