Towards new learning environments—Collective civic actions as learning interventions in post-Communist Belgrade     

Katarina Popović  Maja Maksimović  Aleksa Jovanović 《European Journal of Education》2018,53(3):365-376

This article focuses on the social dimension of well-being, based on a critical analysis of the way it is conceptualised in late capitalism: As the dimensions of individual state of mind and body, something that evolves in the individual realm, stressing personal responsibility and achievement of well-being as a solitary act. Then, the contemporary conceptualisation and approaches to policy making for well-being are compared with the policy of adult and youth education and learning. The perspective of a strong individual orientation, detachment from the social, community and collective aspects and efforts seem to be a common denominator. Agency is considered not only as a possibility for individuals to create and change the environment, but also as a process of active co-construction of social reality. This includes (re)connection with a community, very often through new ways of community learning, civic actions and civic activities. An analysis of how these perspectives converge in civic interventions in urban areas of Belgrade places togetherness at the core of the broader approach to well-being and learning. This article presents several examples of civic activities in urban spaces whose learning character is interpreted within the concept of public pedagogy. The examples presented prevail in the post-Communist countries because public spaces as zones of civic interventions can oppose the controlling authority and through the fight for human and civil rights represent the bottom line of togetherness and collective agency. Learning through collective civic actions thus provides new ways of understanding well-being.  相似文献   

Cytocompatible cellulose nanofibers from invasive plant species Agave americana L. and Ricinus communis L.: a renewable green source of highly crystalline nanocellulose

In this study, the fibers of invasive species Agave americana L. and Ricinus communis L. were successfully used for the first time as new sources to produce cytocompatible and highly crystalline cellulose nanofibers. Cellulose nanofibers were obtained by two methods, based on either alkaline or acid hydrolysis. The morphology, chemical composition, and crystallinity of the obtained materials were characterized by scanning electron microscopy(SEM) together with energy-dispersive X-ray spectroscopy(EDX), dynamic light scattering(DLS), X-ray diffraction(XRD), and Fourier transform infrared(FTIR)spectroscopy. The crystallinity indexes(CIs) of the cellulose nanofibers extracted from A. americana and R. communis were very high(94.1% and 92.7%, respectively). Biological studies evaluating the cytotoxic effects of the prepared cellulose nanofibers on human embryonic kidney 293 T(HEK293 T) cells were also performed. The nanofibers obtained using the two different extraction methods were all shown to be cytocompatible in the concentration range assayed(i.e., 0-500 μg/mL). Our results showed that the nanocellulose extracted from A. americana and R. communis fibers has high potential as a new renewable green source of highly crystalline cellulose-based cytocompatible nanomaterials for biomedical applications.  相似文献   

Comparison of methods: Passing and Bablok regression     

Bilić-Zulle L 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2011,21(1):49-52

The comparison of methods experiment is important part in process of analytical methods and instruments validation. Passing and Bablok regression analysis is a statistical procedure that allows valuable estimation of analytical methods agreement and possible systematic bias between them. It is robust, non-parametric, non sensitive to distribution of errors and data outliers. Assumptions for proper application of Passing and Bablok regression are continuously distributed data and linear relationship between data measured by two analytical methods. Results are presented with scatter diagram and regression line, and regression equation where intercept represents constant and slope proportional measurement error. Confidence intervals of 95% of intercept and slope explain if their value differ from value zero (intercept) and value one (slope) only by chance, allowing conclusion of method agreement and correction action if necessary. Residual plot revealed outliers and identify possible non-linearity. Furthermore, cumulative sum linearity test is performed to investigate possible significant deviation from linearity between two sets of data. Non linear samples are not suitable for concluding on method agreement.  相似文献   

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.  相似文献   

The science(s) of adult education     

Nikola Pastuović 《International Journal of Lifelong Education》2013,32(4):273-291

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.  相似文献

Serbia and Montenegro: the catalytic effects of higher education     

Gordana Zindović‐Vukadinović 《Higher Education in Europe》2004,29(3):329-341

Brain drain has been a long‐lasting phenomenon. It existed in the former Yugoslavia, and was affected by various factors, from political through economic ones to the attractive offers for advanced studies and work in scientific institutions or firms in developed countries. Some ad‐hoc analyses were made concerning individual groups or periods, but there was no systematic monitoring and no complete and all‐inclusive data. It is however possible to draw a picture showing trends in the – mostly one‐way – movement towards highly developed countries.

Therefore, the current study has a mosaic character, which – we hope – shall throw some light and try to explain brain drain in the academic circles of Serbia and Montenegro (former SFRY). As the Republic of Serbia represents the largest component part (about 90 percent), most of the data is about Serbia.  相似文献   

How students perceive teachers’ nonverbal and verbal communication at agricultural universities in Austria,Slovenia and Albania     

Marija Klopčič  Renata Bažok  Helena Virić Gašparić  Karmen Erjavec 《The Journal of Agricultural Education and Extension》2018,24(5):473-483

Purpose: This study attempts to close the research gap created by the fact that existing studies neglect the problem of how effectively agricultural professors from different European countries communicate. The aim is to identify similarities and differences in the numbers of agricultural professors perceived by students as engaging in verbal and nonverbal immediacy communication.

Methodology: An online survey was conducted among students of agricultural universities from Austria, Slovenia and Albania.

Findings: The results show that professors of agriculture from Austria, Slovenia and Albania should generally not be satisfied with their own communication patterns and should thus try to improve their communication. The result also reveals cultural differences in the shares of agriculture professors employing different communication patterns in Austria, Slovenia and Albania. Compared to Austrian and Slovenian students, their Albanian peers perceive that most of their professors use nonverbal immediacy communication. According to Austrian students, the majority of their professors use verbal immediacy. On the contrary, Albanian students assessed that some of their professors employ verbal immediacy.

Practical Implications: The results show the professors of agriculture should improve the way they communicate to students. In particular, the Albanian professors should improve their verbal communication especially in terms of providing timely and quality feedback to students.

Theoretical implications: The study reveals differences in immediacy communication among countries (Austria, Slovenia and Albania) which the scientific literature considers to have a high-context culture.

Originality/Value: Given that no study has yet examined how students perceive professors’ communication in different European countries, this research helps understand the characteristics of agricultural professors’ communication.  相似文献
