Affect Perception in Computer Mediated Communication

The perception of affect influences the subjective perception of an individual’s environment (Isbell & Burns, n.d.). Accurate affect perception leads to increased resilience and positive coping mechanisms when faced with daily life stressors (Robinson, Moeller, Buchholz, Boyd, & Troop-Gordon, 2012). Communication technologies have revolutionized the ways in which individuals connect to one another professionally and socially (Joseph B. Walther, 1992). This study investigated accurate affect perception in computer mediated communication (CMC) from a multidisciplinary perspective. One hundred fifty four research participants ( = 26.84, = 9.66) responded to a self-report questionnaire hosted by Qualtrics.com. A multiple linear regression was conducted, regressing accurate affect perception in the CMC environment on personality, mood, demographic information, and attitude toward CMC variables. The analysis was significant, R2 = .2, F(13,140) = 2.60, p = .003. and lends significant support for previous research in the cognitive neuroscience field that posits positive mood is the most significant predictor of affect perception, β = .12, t(13) = 2.52, p = .008. Proposed methods to increase ones affect perception in CMC and future research directions are discussed

Complexes of triphenylphosphine oxide with lanthanide bromides

The reaction between hydrated lanthanide bromides and triphenylphosphine oxide in 1:3 and 1:4 ratios in ethanol gave a series of complexes [LnBr2(Ph3PO)4]Br (Ln = Pr, Nd, Gd, Tb, Er, Yb, Lu) which contain ethanol and water in the lattice, regardless of the ratio of reactants used. The single crystal x-ray structures of [NdBr2(Ph3PO)4]Br, [GdBr2(Ph3PO)4]Br and [YbBr2(Ph3PO)4]Br have been determined and have an octahedral geometry about the metal ion. Analysis of the bond distances shows that the Ln-O and Ln-Br distance change in accord with the lanthanide contraction, but the non bonded Ln....P distances and the Ln-O-P angles differ significantly for the Yb complex. Conductivity and variable temperature 31P NMR measurements in dichloromethane indicate that the complexes dissolve as [LnBr2(Ph3PO)4]+ for the lighter lanthanides with further ionisation becoming progressively more important for the heavier metals. In methanol more extensive dissociation is apparent. The electrospray mass spectra obtained from methanol solution show [LnBr2(Ph3PO)4]+ is present in high abundance in the gas phase with other species formed due to ligand redistribution, ionisation and solvolysis

QuEChERS: a simple extraction for monitoring quaternary ammonium biocide pollution in soils and antimicrobial resistance

Quaternary ammonium compounds (QACs) are broad-spectrum disinfectants used in a range of everyday materials. Their high usage rates, limited regulation and reporting has meant their environmental release is largely uncontrolled and impact unknown. With links to antimicrobial resistance (AMR) and adsorption to wastewater solids (that are recycled), there is a need for more controlled disposal measures and monitoring. These environmental matrices are highly complex requiring methods that are often laborious and costly to undertake. Using a robust quantitative reversed-phase LC-MS/MS method, we have shown that an ‘off the shelf’ QuEChERS product can reliably extract (<10% RSD) aromatic and aliphatic QACs anticipated within municipal, industrial and agricultural waste from water and soil, with reduced matrix effects of 95.7–104.4% for recoveries of up to 53% from soil when combined with extract dilution. Therefore, unlike current literature, this work has shown that, with minimal development, the QuEChERS product can provide a rapid, effective and low cost preparation for quantifying QAC pollution and monitoring AMR

Developing ‘deep mathematical thinking’ in geometry with 3- and 4-year-olds: A collaborative study between early years teachers and University-based mathematicians

Mathematics in early years settings is often restricted to learning to count and identifying simple shapes. This is partly due to the narrow scope of many early years curricula and insufficient teacher training for exploring deeper mathematical concepts. We note that geometry is an area particularly neglected. In an innovative year-long project, a group of university-based mathematicians and early years teachers collaborated on a child-led exploration of ‘patterns in nature.’ The early years teachers ran the project within the setting, meeting regularly with the mathematicians to discuss potential areas of interest, and to highlight the children’s mathematical thinking. We found that, with the appropriate environment and guidance, the children naturally displayed deep levels of geometrical thinking and found enjoyment and satisfaction in the exploration of mathematical ideas. We define what we mean by the term ‘deep geometrical thinking’ and demonstrate this by looking at three excerpts through the lens of the van Hiele levels of geometric thought, finding that the children are capable of exhibiting thought at level 3 (abstraction), more advanced than previously thought of children of this age. Using a second taxonomy we also assess the range of skills across which they are demonstrating such geometric thought
