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.     

Student teachers’ beliefs about the teacher’s role in inclusive education

The main aim of this research is to examine the basic features of student teachers’ professional beliefs about the teacher’s role in relation to teaching mainstream pupils and pupils with developmental disabilities. The starting assumption of this analysis is that teacher professional development is largely dependent upon teachers’ beliefs about various facets of their professional work. These concepts strongly influence the way that teachers teach and the way that they develop as teachers. The participants in the research are 314 student teachers at the Faculty of Teacher Education of the University of Zagreb who are being prepared to teach in lower grades of primary school. The beliefs were explored using a metaphor technique derived from cognitive theory of metaphor. The differences between beliefs about the perceived teacher role in general, and the perceived teacher role in the education of pupils with developmental disabilities were analysed. The results indicate that the dominant belief about the teacher’s role in teaching mainstream pupils is of the teacher as a transmitter of knowledge, while the findings regarding the dominant belief about the teacher’s role in teaching pupils with developmental difficulties appeared to be self-cantered orientation. No differences were found between student teachers at different study levels. The findings are discussed in the light of the curriculum of initial teacher education.     

Validity of Holland’s theory in adolescence: evidence from a Slovak sample

The underlying calculus assumption of Holland’s theory was tested in two samples of primary school students (N₁ = 400 and N₂ = 250) with an average age of 13.86 and 14.14 years, respectively. Both exploratory and confirmatory multidimensional scaling and Hubert and Arabie’s randomization test of hypothesized order relations were calculated. The circular spatial arrangement of RIASEC types was not confirmed in either of the two samples. The study discusses possible causes of the inappropriateness of using Holland’s model in an adolescent sample.

     

‘Beyond 2015’, within the modern/colonial global imaginary? Global development and higher education

Efforts to emphasize higher education’s role in development have grown in recent years, but important questions remain about the motivations and effects of these initiatives. In this paper, we employ the concept of a ‘modern/colonial global imaginary’ to consider the impact of the enduring power relations and uneven politics of knowledge in the relationship between higher education and development. Specifically, we consider the Association of Commonwealth Universities’ (ACU) ‘Beyond 2015’ campaign, which was launched in anticipation of the new UN Sustainable Development Goals. We argue that despite the ACU’s intention to provide ‘a platform for diverse voices, particularly from the global South’, the campaign was structured in a way that discouraged dissenting perspectives. More broadly, we consider available possibilities and limitations for challenging mainstream development agendas.     

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.     

‘Everywhere they say that it’s harmful but they don’t say how,so I’m asking here’: young people,pornography and negotiations with notions of risk and harm

Debate about pornography and minors has mainly centred on questions of control, regulation and media policy; the urge to protect children from dangers of sexually explicit content being the primary motivator of these conversations. Instead of discussing the use of pornography by minors in the light of relevant research findings, public discourse on these issues is more usually shaped by views of sexual cultures as inherently dangerous to minors, and young people as vulnerable, easily harmed, and endangered by the media. This paper builds on data consisting of 4212 questions about sexuality that were sent by young people in Finland to experts on sexual health. Only 64 (1.5%) of these contributions explicitly focused on pornography. The small number of porn-related submissions suggests that for young people there are other more important concerns in the field of sexuality than pornography, on which adult guidance is sought. This paper argues that young people’s perceptions of pornography are more diverse than is typically assumed in public debate. Young people challenge risk talk by constantly referring to the vagueness of the alleged harm that characterises the discourse of danger that can be found in much public discussion. According to the findings of this study, blurry notions of harm bother young people more than the actual pornographic content they encounter.     

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.
