The science(s) of adult education

This article deals with the problems of forming a scientific system for adult education. The first part contains different concepts of sciences of education in developed countries, with a special emphasis on the difference between pedagogy as ‘practical theory’ and the sciences of education than can withstand meta‐scientific criteria. This is followed by a survey of the educological system of the knowledge of education, and the scientific and non‐scientific knowledge of adult education are contrasted. To enable us to distinguish unambiguously between scientific and non‐scientific knowledge the survey contains some major criteria for determining whether a discipline is a science or not. In this context andragogy, as well as pedagogy, are defined as ‘technological’ disciplines with the task of applying the principles discovered by the sciences of adult education: the educational psychology of adults, the sociology of adult education, the economics of adult education and the educational anthropology. In other words, andragogy is the ‘praxiology of adult education’, i.e. the science of applying scientific knowledge about adult education in the practice of that education. Andragogy could become ‘the general science of adult education’ and acquire a supra‐technological character if it grew into a science of the effectiveness of systems of adult education. In that case andragogy would study the interaction between the elements of the system as well as the interaction between these elements and the subsystems of the educational environment.     

Work-related burnout syndrome in special education teachers working with children with developmental disorders – possible correlations with some socio-demographic aspects and assertiveness

ABSTRACT

The aim of this research was to examine the levels of burnout syndrome dimensions in special education teachers and correlations with some socio-demographic characteristics, job characteristics, and levels of assertiveness. The research included 225 special education teachers from Serbia (82% were women, 18% were men, with the average age of 42.51 ± 9.23 years). Research instruments included Maslach Burnout Inventory, Rathus Assertiveness Schedule, and a socio-demographic questionnaire. There were differences in all burnout dimensions in relation to types of students’ special needs. Higher levels of burnout symptoms were observed in teachers working with children with motor skill disorders. The assertiveness scores had a significant negative correlation with emotional exhaustion and depersonalisation, and a positive correlation with a lack of accomplishment. The results obtained may help in the planning of the adequate preventative measures for improving the mental health of those professionals.     

Public Libraries in the Eyes of the LGBTIQ Community: The Case of Croatia

ABSTRACT

The achievement of social justice, which implies the development of collections and the design of services for different user groups, is an objective present in the mission of public libraries. Since the 1950s, Croatian public libraries have been continuously developing collections and services for different user communities. However, one user community has remained largely unrecognized – LGBTIQ people. Therefore, the aim of the research presented in this paper is to examine the importance of the role of public libraries in the life of the LGBTIQ community in the Republic of Croatia. With a sample of 259 respondents, information behaviors, attitudes and experiences of LGBTIQ people in relation to public libraries have been examined via an online survey. In particular, this study explored the extent to which members of public libraries differ from non-members. The obtained results should contribute to a better understanding of the information needs and behavior of members of sexual minorities and help bring this group of users closer to (Croatian) public libraries by ensuring that libraries more adequately respond to their needs.     

Entrepreneurialism at the University of Novi Sad

What does being an entrepreneurial university mean? The University of Novi Sad in Serbia is taken as an example of how one University in a transition country, which was lacking tradition in entrepreneurial practices, is striving to become an entrepreneurial university. Examples of new practices are also described such as the establishment of a university incubator, introduction of a course in entrepreneurship offered to all students, diversification of income sources, development of institutional links and strategies for the closer flow of ideas, information, and research results between the University and its stakeholders.     

THE LISBON CONVENTION ON THE RECOGNITION OF QUALIFICATIONS CONCERNING HIGHER EDUCATION IN THE EUROPEAN REGION: AN EXAMPLE OF SUCCESSFUL CO‐OPERATION BETWEEN THE COUNCIL OF EUROPE AND UNESCO

On the eve of the adoption of the new Council of Europe ‐ UNESCO Convention, this article goes back to the first agreement between the two international organizations to step up their co‐operation in the field of academic recognition and retraces the different stages that led to the final completion of the legal text. It offers an overview of the entire process, analyzing the development of the basic concepts of the Convention, highlighting controversial issues, and demonstrating the complex process of consultation in a wider and diversified Europe that will be brought to completion at the Lisbon Diplomatic Conference. This article, in a slightly different form, will be presented as a background document at the Lisbon Conference.     

Diversity of Terrestrial Cyanobacteria Colonizing Selected Stone Monuments in Serbia

The presence of biofilms on stone monuments can lead to biodeterioration processes that significantly lower not only the aesthetic value of cultural heritage sites but also cause considerable physical and chemical damage to stone surfaces. In terrestrial environments, cyanobacteria have a significant role in biofilm formation on a variety of natural and artificial stone substrata, including granite, sandstone, limestone, lime mortar, etc. Studies on cyanobacterial diversity and estimation of biodeteriorative activity on stone cultural heritage objects can be very important for conservators and restorers, and cyanobacteria removal from stone monuments is currently a great challenge for conservation science. In that sense, the diversity of terrestrial cyanobacteria was investigated at six localities in Serbia. Samples for cyanobacterial analyses were taken from surface biofilms covering different substrata: granite and lime mortar (The Monument to the Unknown Hero), sandstone (Branko's Bridge, Eiffel’s Lock) and carbonate rock (Medieval tombstones from Mramorje and Rasti?te, Gradac Monastery). A total of 18 cyanobacterial taxa were identified. The highest diversity was found on carbonate rock, followed by sandstone. Cyanobacteria were also recorded on an artificial substratum – lime mortar, while cyanobacteria were not found on granite. All detected cyanobacteria seriously impaired the structural and aesthetic integrity of the studied monuments via mechanical and chemical actions, so their presence must not be overlooked.     

Use of biochemical parameters for non-invasive screening of oesophageal varices in comparison to elastography-based approach in patients with compensated advanced chronic liver disease

IntroductionOesophageal varices are routinely diagnosed by esophagogastroduodenoscopy (EGD), and their bleeding has high mortality. We aimed to evaluate diagnostic performance of biochemical tests in comparison to elastography-based approaches, as non-invasive alternatives to EGD, for ruling-out high risk oesophageal varices (HRV).Material and methodsRetrospective analysis of patients (N = 861) who underwent liver stiffness measurement (LSM) by transient elastography (TE) in a single centre over 5-year period, with available results of EGD (within 3 months from LSM). Only patients with suspicion of compensated advanced chronic liver disease (cACLD) defined by LSM ≥ 10 kPa were included comprising the final cohort of 73 subjects. Original and expanded Baveno VI criteria (B6C), controlled attenuation parameter (CAP), platelet count (PLT), aspartate aminotransferase to PLT ratio index (APRI), Fibrosis-4 index (FIB4), model for end stage liver disease (MELD) score were evaluated against the results of EGD that served as the reference method.ResultsAnalysed patients had median age 62 years, 59/73 (0.81) were males, 54/73 (0.74) had alcoholic/non-alcoholic fatty liver disease, and 21/73 (0.29) had HRV. In multivariate logistic regression analysis only LSM and PLT were independently associated with HRV. The best performing tests for ruling-out HRV (% of spared EGD; % of missed HRV) were respectively: LSM < 20 kPa (53.4%; 0%), B6C (38%; 0%), Expanded B6C (47.9%; 4.8%); PLT > 214x10⁹/L (21.9%; 0%); FIB4 ≤ 1.8 (21.4%; 0%), APRI ≤ 0.34 (12.3%; 0%). CAP, MELD = 6 alone or combined with PLT > 150(x10⁹/L) did not show acceptable performance.ConclusionThe best performing biochemical tests for ruling-out HRV in our cohort of patients were PLT and FIB-4, but they were still outperformed by elastography-based approaches.Keyword: portal hypertension, cirrhosis, platelet count, esophageal varices, non-invasive tests     

Visual-Motor Integration,Executive Functions,and Academic Achievement: Concurrent and Longitudinal Relations in Late Elementary School

ABSTRACT

Research Findings: Using data from a short-term longitudinal study of 343 third-, fourth-, and fifth-grade students, we investigated visual-motor integration (VMI) skills as a predictor of direct assessments of executive functions (EFs) and academic achievement. This is the first study to investigate relations among these three constructs in late elementary school. VMI predicted change in EFs from fall to spring. EFs and VMI were independently associated with math and English/language arts standardized test scores. When controlling for earlier achievement test scores, EFs—but not VMI—remained a significant predictor of later academic achievement. Results indicate that VMI may help support the continued development of EFs in late elementary school, but EFs appear to be comparatively more important as a direct predictor of continued academic development during this age period. Practice or Policy: VMI is a complex ability that combines fine motor coordination (an aspect of school readiness) and visual-spatial reasoning skills. VMI has been identified as an influential predictor of early academic development, but it has been neglected in middle childhood studies. Our results suggest that VMI remains important through the end of elementary school for the continued development of children’s EFs and therefore merits more attention from researchers and educators.     

Approximation based on orthogonal and almost orthogonal functions

In this paper, we define a class of almost orthogonal rational functions of Legendre type in a new manner. Relations of these functions with classical exponentional functions orthogonal over interval (0, ∞), as well as classical polynomials orthogonal over (0, 1) are explained. Defining relations of these functions can be used for designing almost orthogonal filters. These filters are generators of orthogonal signals and can be successfully applied in finding the best signal approximation in the sense of the mean square error. The filters orthogonal property enables building of physical (in this case electrical) models of dynamical systems (the sources of signals to be approximated) either with less components for the same model accuracy or higher accuracy for the same number of components than the other known models. New filters represent further improvement of previously designed filters, by the same authors, in the sense of simplicity, higher accuracy, lesser approximation time and even a possibility to approximate signals generated by systems with built-in imperfections. Series of experiments were performed to analyze the dependence of approximation accuracy and the number of filters sections.
