Social Networking for Learning in Higher Education: Capitalising on Social Capital

YesThis study explores the evolution of student-led social networking groups initiated and sustained by a cohort of undergraduate students over a 3-year time frame. The study contributes to this growing area of research by exploring the impact of peer-led, peer-supported informal learning through social media networks. Social capital is a useful lens through which to understand the findings, and particularly in interpreting descriptions of the evolution of the group over time. The findings suggest that students build bridging social capital to support the transition into higher education, form relationships and learn collaboratively through a large cohort-based Facebook group. Over time, this form of social capital and the use of the Facebook group declines due to a lack of perceived reciprocity and an increased perception of competitiveness amongst peers. However, there is accompanied by a subsequent rise in the building of bonding social capital between closer peer relationships facilitated through the use of various WhatsApp groups. The findings have implications for considering how social networking might support the student journey towards more nuanced, more personalised collaborative learning and a move towards more self-directed learning

Social Media for Learning: Advancing Theoretical Frameworks to Understand Complex Learning Environments

Students in higher education are driving the informal use of social media to support their cognitive and socio-emotional learning experiences during their undergraduate studies, with a growing literature base supporting the use of such technologies.  This paper highlights a need to take a longitudinal approach to explore how students’ use of social media tools may change over time and promotes the use of social learning theories as a useful lens through which to explain this complex and situated learning of a given community of practice. It argues that to enhance social media pedagogies the research community needs to explore more explicitly ways that innovative pedagogy can inform theory development within the field, and equally how a greater maturity in understanding those theories can enhance our pedagogical practices.  The potential for cultural historical activity theory (CHAT) as a framework for researching the multi-dimensional, or dialectical, interactions that may occur in the social media space is examined.  CHAT is promoted as a useful theory for introducing a greater focus on the role of the social media tool itself in mediating learning.  The paper concludes by proposing that that whilst existing social learning theories provide useful starting points for making sense of how social media can support learning, there may also be a need for the advancement of such theoretical frameworks to ensure that we develop theory capable of exploring the complexity of learning that could take place in social media spaces

‘It put me in their shoes’: challenging negative attitudes towards asylum seekers among Australian children

This paper evaluates a short school-based intervention run by Australian Red Cross, designed to reduce children’s prejudice towards asylum seekers. A total of 121 children aged between 10 to 12 in four schools in Perth, Western Australia, completed questionnaires at Time 1 (pre-intervention), Time 2 (immediately after the intervention), and Time 3 (8-9 months after the intervention). The intervention used a mixture of approaches: providing information, encouraging empathy, making positive social norms more explicit, and fostering imagined contact with asylum seekers. The intervention content was also reinforced by teachers throughout the school year. The study found that the intervention was effective in increasing the children’s positivity towards asylum seekers, reducing prejudiced attitudes, and increasing intentions to interact with asylum seekers. It also found that the intervention increased the children’s accuracy in defining ‘asylum seeker’ and ‘refugee’. These results occurred both in the short-and long-term, although there was some regression over time

The prevalence of constant supportive observations in a high, medium and low secure service

Aims and Method We explored the prevalence and use of constant supportive observations (CSO) in high, medium and low secure in-patient services in a single NHS mental health trust. From clinical records, we extracted data on the length of time on CSO, the reason for the initiation of CSO and associated adverse incidents for all individuals who were placed on CSO between July 2013 and June 2014. Results A small number of individuals accounted for a disproportionately large amount of CSO hours in each setting. Adverse incident rates were higher on CSO than when not on CSO. There was considerable variation between different settings in terms of CSO use and the reasons for commencing CSO. Clinical Implications The study describes the prevalence and nature of CSO in secure forensic mental health services and the associated organisational costs. The marked variation in CSO use between settings suggests that mental health services continue to face challenges in balancing risk management with minimising restrictive interventions

Uptake of silicon in barley under contrasting drought regimes

Purpose: Silicon (Si) accumulation in plant tissues plays a vital role in alleviating biotic and abiotic stresses, including drought. Temperate regions are predicted to experience reductions in the quantity and frequency of rainfall events, potentially impacting plant Si uptake via the transpiration stream. Despite the importance for predicting plant responses to Si amendments, the effects of changes in rainfall patterns on Si uptake in cereals have not been characterised. Methods: Five watering regimes were applied based on predicted precipitation scenarios, varying the quantity of water delivered (ambient, 40% or 60% reduction) and watering frequency (40% reduction in quantity, applied 50% or 25% of ambient frequency), and the effects on growth and leaf Si concentrations of a barley landrace and cultivar were determined. Results: Reductions in the quantity of water reduced plant growth and yield, whereas reducing the watering frequency had little impact on growth, and in some cases partially ameliorated the negative effects of drought. Reductions in quantity of water lowered leaf Si concentrations in both the cultivar and landrace, although this effect was alleviated under the drought/deluge watering regime. The landrace had greater leaf Si concentration than the cultivar regardless of watering regime, and under ambient watering deposited Si in all cells between trichomes, whereas the cultivar exhibited gaps in Si deposition. Conclusion: The impact of future reductions in rainfall on barley productivity will depend upon how the water is delivered, with drought/deluge events likely to have smaller effects on yield and on Si uptake than continuous drought

An efficient platform for astrocyte differentiation from human induced pluripotent stem cells

Summary: Growing evidence implicates the importance of glia, particularly astrocytes, in neurological and psychiatric diseases. Here, we describe a rapid and robust method for the differentiation of highly pure populations of replicative astrocytes from human induced pluripotent stem cells (hiPSCs), via a neural progenitor cell (NPC) intermediate. We evaluated this protocol across 42 NPC lines (derived from 30 individuals). Transcriptomic analysis demonstrated that hiPSC-astrocytes from four individuals are highly similar to primary human fetal astrocytes and characteristic of a non-reactive state. hiPSC-astrocytes respond to inflammatory stimulants, display phagocytic capacity, and enhance microglial phagocytosis. hiPSC-astrocytes also possess spontaneous calcium transient activity. Our protocol is a reproducible, straightforward (single medium), and rapid (<30 days) method to generate populations of hiPSC-astrocytes that can be used for neuron-astrocyte and microglia-astrocyte co-cultures for the study of neuropsychiatric disorders. : Brennand, Goate, and colleagues report a rapid and robust method for the differentiation of highly pure populations of replicative astrocytes from human induced pluripotent stem cells (hiPSCs) via a neural progenitor cell (NPC) intermediate. hiPSC-astrocytes resemble primary human fetal astrocytes, have a transcriptional signature consistent with a non-reactive state, respond to inflammatory stimulants, and enhance microglial phagocytosis. Keywords: human induced pluripotent stem cell, iPSC, astrocyt

Reciprocal effects of silicon supply and endophytes on silicon accumulation and Epichloë colonization in grasses

Cool season grasses associate asymptomatically with foliar Epichloë endophytic fungi in a symbiosis where Epichloë spp. protects the plant from a number of biotic and abiotic stresses. Furthermore, many grass species can accumulate large quantities of silicon (Si), which also alleviates a similar range of stresses. While Epichloë endophytes may improve uptake of minerals and nutrients, their impact on Si is largely unknown. Likewise, the effect of Si availability on Epichloë colonization remains untested. To assess the bidirectional relationship, we grew tall fescue (Festuca arundinacea) and perennial ryegrass (Lolium perenne) hydroponically with or without Si. Grasses were associated with five different Epichloë endophyte strains [tall fescue: AR584 or wild type (WT); perennial ryegrass: AR37, AR1, or WT] or as Epichloë-free controls. Reciprocally beneficial effects were observed for tall fescue associations. Specifically, Epichloë presence increased Si concentration in the foliage of tall fescue by at least 31%, regardless of endophyte strain. In perennial ryegrass, an increase in foliar Si was observed only for plants associated with the AR37. Epichloë promotion of Si was (i) independent of responses in plant growth, and (ii) positively correlated with endophyte colonization, which lends support to an endophyte effect independent of their impacts on root growth. Moreover, Epichloë colonization in tall fescue increased by more than 60% in the presence of silicon; however, this was not observed in perennial ryegrass. The reciprocal benefits of Epichloë-endophytes and foliar Si accumulation reported here, especially for tall fescue, might further increase grass tolerance to stress
