In this paper we grapple with the ways in which real-world issues directly impact children’s lives and ask what else gets produced through encounters with children’s global news media, specifically within the contexts of the United Kingdom and Norway. Our aim is to experiment with storytelling and worldling practices as a means to open up generative possibilities to encounter and reconfigure difficult knowledges. We take two contemporary events, the 2017 Grenfell Tower fire tragedy in London and the 2018 Marjory Stoneman Douglas High School shooting massacre in Florida, as a means to attend to ways in which affects are materialised across multiple times and spaces. News reports of these harrowing events, alongside what they produced in terms of child activism, racism and toxic masculinity, provided a catalyst for a feminist new materialist experiment in generating other knowledges through material-affective-embodied encounters. Newspapers, glue, sticky tape, string, torches, bags and a cartridge for a firearm were used in important work within a speculative workshop, where a small number of early childhood researchers came together to be open to multiple and experimental ways of (k)not-knowing to formulate collectively shared problems. Following Manning (2016), we recognise that to avoid getting stuck in familiar ways of thinking and doing we need to undertake research differently. We wondered how the re-materialisation of these events (through objects, artefacts, sounds and images) might shift our thinking about childhood in other directions. We dwell upon the affective work that these high-profile news events perform and how they might become rearticulated through affective encounters with materiality. Attending to how these events worked on us involves staying with the trouble (Haraway, 2016) as it becomes reignited, mutated and amplified across time and in different contexts. Our goal is to generate other possibilities that seek to reconfigure the ‘image of the child’. By resisting comforts of recognition, reflection and identification, we reach beyond what we think we know about how children are in the world and instead argue for their entanglement with difficult knowledges through our and their world-making practices.

The paper presents the design and fabrication of a low-cost and easy-to-fabricate laser-induced graphene sensor together with its implementation for multi-sensing applications. Laser-irradiation of commercial polymer film was applied for photo-thermal generation of graphene. The graphene patterned in an interdigitated shape was transferred onto Kapton sticky tape to form the electrodes of a capacitive sensor. The functionality of the sensor was validated by employing them in electrochemical and strain-sensing scenarios. Impedance spectroscopy was applied to investigate the response of the sensor. For the electrochemical sensing, different concentrations of sodium sulfate were prepared, and the fabricated sensor was used to detect the concentration differences. For the strain sensing, the sensor was deployed for monitoring of human joint movements and tactile sensing. The promising sensing results validating the applicability of the fabricated sensor for multiple sensing purposes are presented.

Grape scale, Diaspidiotus uvae (Comstock), is a pest of grapes, Vitus spp., in the south-central United States. This study compared Julian days and cumulative degree-days (DD at base 10°C accumulated after 1 April) to grape scale biology and control in Arkansas. On the average, first generation crawlers began emerging 14 May (274 DD) and peaked on 20 May (356 DD). First generation winged males began emerging on 26 June (794 DD) and peaked 13 July (1,108 DD). Second generation crawlers began emerging on 20 July (1,166 DD) and peaked on 12 August (1,549 DD). Second generation wingless males began emerging on 31 August (1,857 DD) and peaked on 18 September (2,026 DD). Relative to untreated vines, vines treated with chlorpyrifos at bud swell (early April) or as late as early May (near grape bloom) realized at least an eight-fold reduction in the number of crawlers and adult males per sticky tape trap. Vines receiving the second application near grape bloom had significantly fewer crawlers in May, August and September than vines sprayed once in late April. A chlorpyrifos treatment in early April provided at least a 30-d lethal residual on grape against grape scale crawlers that emerged during May.
