Decision Science and Applied Neuroscience: Emerging Possibilities

Recent neuroscientific research describes how the brain and extended nervous system make decisions. This article depicts current theory as it relates to decision‐making strengths, shortcuts, simplifications, biases, and serious data restricting habits of the brain. This information demonstrates that the brain, both individually and collectively, can be a deceptive guide for decision making in emergent situations when information is based on preexisting, subconscious frames of reference. Training is proposed to strengthen conscious information‐processing capacity.     

Stability of switching linear systems with switching signals driven by stochastic processes

This paper presents conditions to assure the exponential stability in probability for autonomous switching linear systems. The switching signal acting on the autonomous system produces intervals that follow independent, identically distributed stochastic processes—the stability then follows by verifying simple-to-check linear matrix inequalities.     

The current state of human performance technology: A citation network analysis of Performance Improvement Quarterly, 1988–2010

This study conducted a citation network analysis (CNA) of human performance technology (HPT) to examine its current state of the field. Previous reviews of the field have used traditional research methods, such as content analysis, survey, Delphi, and citation analysis. The distinctive features of CNA come from using a social network analysis approach to see relational and network patterns in the citation data. This CNA found that the Performance Improvement Quarterly network showed more widely but loosely connected and less centralized structural attributes than the human resource development network; the 10 most influential articles in the field were identified; frequently co‐cited articles were recognized as having a strong relationship by subsequent researchers; and five cohesive subgroups showed key topics in the field (performance, instructional design, performance support, organization/workplace, and transfer of training). Implications from the results of the CNA were elaborated on for future research in HPT.     

Strategic Embodiment in Virtual Spaces: Exploring an on-line discussion about sexualities equality in schools

This paper analyses patterns of participation on a voluntary anonymous Web-based discussion forum, open to students and faculty in one UK university, concerning sexualities equality in schools. Analysis revealed that participants often rejected the security of anonymity and strategically embodied themselves and others (as gay, straight, parents, etc.) to provide authority and ethical grounding for certain arguments. These embodied arguments invited engagement and promoted dialogue. We found that while personal embodiments were crucial for meaningful interaction, they also brought the risk of personalizing systematic inequality and fostering a victimization discourse. In the light of this, we argue that both individual and collective perspectives are crucial for promoting sexualities equality in school.     

A New Student Learning Focus for the Academic Library: From Geographical Proximity of the Learning Commons to Organizational Proximity within the Library

In 2015, student learning programs at the University of Saskatchewan moved organizationally to the university library. While these services resided physically in the library as part of the Learning Commons partnership, this recent change presents the library with a new focus and responsibility for broader student learning support and academic skill development. Highlighting examples of organizational integration of student learning support, this article uses a proximity perspective, suggesting that geographical proximity of services in the learning commons does not go far enough to achieve the deeper collaboration and integration necessary for holistic and integrated learning, and that organizational proximity is needed.     

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.     

Suitable work for women? Roles,relationships and changing identities of ‘other adults’ in the early years classroom

This article explores some of the issues around the agenda for workforce reform as it applies to professionals who work in early years classrooms (4–7 year olds), who work alongside class teachers in supporting learning. Their changing roles, responsibilities and professional identities are examined through a small scale case study of four women, two nursery nurses and two teaching assistants, from an infants school in a suburb of Bristol. Their close professional and personal relationships with the six female class teachers with whom thery work are considered. Their stories are analysed for their significance as women whose levels of skill and dedication are undervalued in terms of career structure, salary and job security. Whilst contributing to the debates around the changing roles and the valuable work of teaching assistants, this research endorses the view that these professionals' voices are too often silenced in educational debates and in strategic decision making.     

Understanding of the alphabetic principle through invented spelling among hearing‐impaired children learning to read and write: experimentation with a pedagogical approach

Given the problems experienced by hearing‐impaired individuals in learning the written language, a pedagogical approach was tested. The study examined the links between the development of representations of alphabetic system and the results in reading and writing of first graders. In the study, there were 31 hearing‐impaired children and 25 hearing ones. Invented spelling was measured three times during the school year. Reading and writing tests were given at the end of the year. The results obtained revealed a similarity between the learning profile of the hearing‐impaired children and that of the hearing children. It also demonstrated the importance of the work done through invented spelling, among the hearing‐impaired children. Thus, like their hearing peers, hearing‐impaired children are able to use procedures to process the written word based on the alphabetic principle, but continuous support‐implying invented spelling constantly adjusted to the progression of their representations must be provided.     

Dangerous spaces: constructing and contesting sexual identities in an online discussion forum

This paper explores ways in which the research design of an anonymous online discussion forum on sexual orientation and schooling fostered the creation, maintenance and/or disruption of linguistic constructions of participant identity. The paper focuses on the presentation of self and the performance of sex–gender–sexuality within a research environment carefully designed as a ‘safe space’: an environment in which the body is conspicuous by its absence, and the construction and performance of identity relies on language alone. We explore the lines of power operating firstly between ourselves as researchers and the discussion participants, and secondly between the participants themselves, and consider the particular complexities involved in both creating and researching an online environment where simply to take part is to be at risk, and where the intervention or participation of the researchers may act both as a silencing mechanism and as a source of danger.
