Sentiment score of LGBT categories in news media over a decade (2010–2020).

Sentiment scores are assigned to collocates on a valence scale of 1–5, where 1 (very negative), 3 (neutral), 5 (very positive). Given that a neutral score is denoted by ‘3’, coverage about Pink Dot (the local pride event) was comparatively the most positive, followed by neutral scores for Lesbian, Gay, LGBT, Transgender. The only set of identity marker keywords that dipped slightly below the neutral threshold were Bisexual and 377A (the law against homosexual relations).</p

Coverage size over time of LGBT keywords in Singapore news media over a decade (2010–2020).

Overall increase in mainstream media mentions of LGBT keywords over the decade from 2010 to 2020. Coverage was skewed in favor of keywords related to gay identity markers, followed by transgender identity markers, and with lesbian and bisexual identity markers lagging in comparison.</p

Comparative disparity in overall coverage size of LGBT keywords in news media over a decade from 2010 to 2020.

Over the span of the decade (2010–2020), comparative disparities in coverage volume were evident. On average, Gay identity markers (keywords including ‘gay(s)’, ‘gay man/men’) were mentioned at a higher frequency than other identity markers; with coverage of this group outstripping Bisexual keywords (including ‘bisexual(s)’, ‘bisexuality’) by seven times, Lesbian (keywords including ‘lesbian(s)’) by four, Transgender (keywords including ‘transgender(s)’, ‘transsexual(s)’, ‘transvestite(s)’) by two, even outnumbering general keywords denoting LGBT identities as a collective whole (including keywords ‘LGBT(Q)’, ‘GLBT’, ‘homosexual(s)’, ‘pansexual(s)’).</p

Porous Co₃O₄ Nanorods–Reduced Graphene Oxide with Intrinsic Peroxidase-Like Activity and Catalysis in the Degradation of Methylene Blue

A facile two step process was developed for the synthesis of porous Co₃O₄ nanorods–reduced graphene oxide (PCNG) hybrid materials based on the hydrothermal treatment cobalt acetate tetrahydrate and graphene oxide in a glycerol–water mixed solvent, followed by annealing the intermediate of reduced graphene oxide-supported Co­(CO₃)_0.5(OH)·0.11H₂O nanorods in a N₂ atmosphere. The morphology and microstructure of the composites were examined by X-ray diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy and Raman spectroscopy. It is shown that the obtained PCNG have intrinsic peroxidase-like activity. The PCNG are utilized for the catalytic degradation of methylene blue. The good catalytic performance of the composites could be attributed to the synergy between the functions of porous Co₃O₄ nanorods and reduced graphene oxide
