title: Oil prices and Stock Market anomalies

authors: Cheema, Muhammad A.

subjects: oil prices

abstract: This paper examines the relationship between oil prices and stock market anomalies  in China, the largest oil importer country in the world. Prior literature documents both a positive and negative relationship between oil prices and the stock market. The explanation of a positive relationship is supported by the argument that rising oil prices are interpreted as a positive signal by investors. Consequently, rising oil prices lead stock prices above their fundamental values and that they subsequently correct. Therefore, we hypothesise that stock market anomalies are stronger following rising oil prices since returns associated with anomalies reflect mispricing. The results, consistent with the hypothesis, show stronger return predictability for individual anomalies following an increase in oil prices than for a decrease in oil prices. The results are even stronger once we construct a mispricing score based on composite mispricing of all the anomalies.

title: Some Ruthenium Derivatives of Penta-1,4-diyn-3-one

authors: Bruce, Michael I.

abstract: The reaction between Ru(C≡CH)(dppe)Cp* (1) and oxalyl chloride affords ({Ru(dppe)Cp*}C≡C)₂CO (2) in 72% yield. Methylation (MeOTf) of 2 occurs first on the carbonyl oxygen, affording [({Ru(dppe)Cp*}C≡C)2C(OMe)]OTf ([3]OTf). A second methylation of [3]⁺ on the alkynyl Cβ proceeds slowly, affording [{Cp*(dppe)Ru}CCMeC(OMe)CC{Ru(dppe)Cp*}][OTf]₂ ([4][OTf]₂), whereas protonation of [3]+ occurs readily to give crystallographically characterized [{Cp*(dppe)Ru}CCHC(OMe)CC{Ru(dppe)Cp*}][OTf]₂ ([5][OTf]₂). The molecular structures of [3]OTf and [5][OTf]2 suggest that polarization by the CO group results in significant contributions from the alkynyl-allenylidene or alkynyl-carbyne mesomers, respectively. Reaction of 2 in refluxing MeOH containing [NH4]PF6 results in partial methanolysis to give Ru{C≡CC(O)CH═CH(OMe)}(dppe)Cp* (6). Knövenagel condensation of 2 with CH₂(CN)₂ affords {[Ru(dppe)Cp*]C≡C}₂C═C(CN) ₂ (7). The related asymmetric complex {Cp*(dppe)Ru}C≡C[C═C(CN)₂]C≡CC≡C{Ru(dppe)Cp*} (8) was obtained from the reaction between Ru{C≡CC(CN)═C(CN)₂}(dppe)Cp* and lithiated Ru(C≡CC≡CH)(dppe)Cp*. Single-crystal structural determinations of 2, [3]OTf, [5][OTf]₂, 6, 7, and 8 are reported, together with a supporting computational study of relevant electronic structures.

title: “This is not us”: But actually, it is. Talking about when to raise the issue of colonisation.

authors: Waitoki, Waikaremoana

abstract: This paper is a commentary on some of the responses to the public narrative of the events after the March 15th Christchurch attack. Several colleagues had publicly and privately, offered their views on the Government’s and media outlets use of terms such as ‘unprecedented’, ‘our loss of innocence’ and ‘our darkest day’. A fiery and empassioned exchange of words emerged on social media about the statement: ‘This is not us’. By exposing the counternarrative to these emotion laden terms, a shady past, and invisible present was revealed. However, the timing of the talk about colonisation also seemed out of step with the need for sensitivity. This paper also explores the role of White supremacy and causal racism in New Zealand. A personal I/we/us narrative style is used throughout the paper to describe how Muslim and Maori lives intersected prior to, and after the attack. The timeline of events is primarily 1 week, and up to 6 weeks post the attack.
