Science and Technological Development: Towards the Enhancement of Endogenous Capacities—A View from the Federal Republic of Yugoslavia

Following a tour d'horizon of the development of science and science policy in former Yugoslavia, the author focuses on the application of science to development in this country after the Second World War. In particular, she examines the role of computer science in which Yugoslav scientists developed much endogenous capacity. The events following the break-up of Yugoslavia led to the isolation and the emigration of scientists, academics, and graduate students, particularly from Serbia, in the reduced Yugoslavia that remained after the break-up. During the period of sanctions, Yugoslavia was denied even the right to participate in TEMPUS projects that were underway. The TEMPUS III projects in which Yugoslavia can participate are not very helpful in rebuilding the scientific capacity of the country. The country needs assistance, possibly best given through twinning arrangements with universities in other countries, to rebuild its scientific capacity. Economic aid to rebuild infrastructures is also needed. Only when talented young scientists can look forward to a future at home will they no longer seek to emigrate.     

Application of functional derivatives to analysis of complex systems

The application of the functional derivatives to the mathematical modeling of complex systems is studied here. The connection of functional derivatives with total differentials in Banach spaces is shown. Local and global existence theorems for the linear equations in total differentials are proved. Consequently, a total integrability conditions are derived for the case of linear equations with the functional derivatives. Some illustrative examples are included.     

Testing Inequality Constrained Hypotheses in SEM Models

Researchers often have expectations that can be expressed in the form of inequality constraints among the parameters of a structural equation model. It is currently not possible to test these so-called informative hypotheses in structural equation modeling software. We offer a solution to this problem using Mplus. The hypotheses are evaluated using plug-in p values with a calibrated alpha level. The method is introduced and its utility is illustrated by means of an example.     

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.     

Empowering learners with personalised learning approaches? Agency,equity and transparency in the context of learning analytics

Abstract

The emergence of personalised data technologies such as learning analytics is framed as a solution to manage the needs of higher education student populations that are growing ever more diverse and larger in size. However, the current approach to learning analytics presents tensions between increasing student agency in making learning-related decisions and ‘datafying’ students in the process of collecting, analysing and interpreting data. This article presents a study that explores staff and student experience of agency, equity and transparency in existing data practices and expectations towards learning analytics in a UK university. The results show a number of intertwined factors that have contributed to the tensions between enhancing a learner’s control of their studies and, at the same time, diminishing their autonomy as an active agent in the process of learning analytics. This article argues that learner empowerment should not be automatically assumed to have taken place as part of the adoption of learning analytics. Instead, the interwoven power relationships in a complex educational system and the interactions between humans and machines need to be taken into consideration when presenting learning analytics as an equitable process to enhance student agency and educational equity.     

Emotional Behavior Problems,Parent Emotion Socialization,and Gender as Determinants of Teacher–Child Closeness

Research Findings: Drawing from a diverse community sample of 89 children, ages 4–6, their primary caregivers and teachers, this study examined the interplay of child emotional behavior problems, parent emotion socialization practices, and gender in predicting teacher-child closeness. Teachers reported on perceptions of closeness with children. Parents and teachers reported on children’s emotional behavior problems, as indexed by overanxious behavior, overt, and relational aggression. Regression models revealed that higher relational aggression related to closer teacher-child relationships for all children of parents who employed minimization as an emotion socialization practice. Similarly, higher overt aggression related to closer teacher-child relationships for girls who experienced parent minimization. An analogous pattern of results emerged, such that lower parent emotional support buffered girls against the negative effects of higher relational aggression on teacher-child closeness, whereas higher parent emotional support related to lower levels of closeness for these girls. These findings contradict prior research linking supportive emotion socialization practices (e.g., empathy, comforting) to socioemotional competence and unsupportive practices (e.g., minimization, punishment) to poor school adjustment. Practice or Policy: Findings have implications for improving children’s classroom experience by identifying parent emotion socialization and gender as contexts for understanding child emotional behavior problems in relation to teacher-child closeness.     

The influence of experience on pre-service and novice teachers – the Croatian perspective

This paper researches students’ and teacher trainees’ personal experience of student-centred teaching during their education in grades 1–4 of primary school. The questionnaire comprised 45 statements and was completed by 403 primary school teacher trainees and 535 students (future teachers) at Faculties of Teacher Education in Croatia. The research results show that students do not have sufficient prior experience that they could use as inspiration in their future teaching practice and that in the course of their education they were mainly exposed to traditional approach to teaching. The majority of teacher trainees are aware of the importance of student-centred teaching although they cannot fully give up the control of students and educational process. This research opens up the issue of a paradigm change within the teaching system and education in Croatia as well as the issue of changes within education and professional development of teachers.     

Does the Institutional Type Matter?: Slovak Higher Education on Its Way to Diversity

The paper focuses on the issue ofthe development of new institutional types inSlovak higher education. It is based on theempirical research conducted in 2001 among thesample of university graduates in Slovakia. Themain focus of the paper is the comparison ofpublic, non-state and private higher educationwith respect to their background, academicexperience and first labour market experienceafter graduation. The discussion of theseissues has shown that the road of Slovakia toan institutionally diversified higher educationsystem is still at its early stages. However,graduates from existing private highereducation institutions are competitive on thelabour market, and the same is true forgraduates from non-state (church) highereducation. The results of the study can be usedas an argument in favour of furtherdiversification of institutional types in thecontext of Slovak higher education.     

School-level facilitators of inclusive education: the case of Serbia

Relying on Bronfenbrenner’s ecological model, this paper attempts to identify school-level factors that contribute to effective implementation of inclusive education. We also explored how government policy, with emphasis on individual education plans, school teams, Roma assistants and inter-sectorial committees, is implemented at the school level. Qualitative data were collected from various informants (students, parents, teachers, school associates, Roma assistants and local community representatives) in five schools selected on the basis of regional distribution and success in supporting diverse student needs. Two core categories of school-level facilitators were generated: inclusive practices and inclusive culture. Within the first category, which refers to concrete actions and relationships in the school and local community, five themes emerged: individualisation and use of individual education plans; cooperation between teachers and school inclusive education expert team; cooperation with internal and external specialists; cooperation with parents, and cooperation with the local community. The second category, which reflects beliefs, values and implicit school norms, was further divided into five subcategories: willingness for life-long learning; proactive stance; sense of teamwork; sophisticated personal philosophies of development and learning; and acceptance of difference. We concluded that successful schools have developed into professional learning communities. Finally, recommendations for improving relevant practices were provided.
