title: 2-Ferrocenyl-substituted pyrylium ions from coupling of ethynylferrocene with cyclomanganated chalcones

authors: Prasad, Narendra Jai

subjects: pyrylium salts

abstract: 2-Ferrocenyl-substituted pyrylium salts are produced when orthomanganated chalcones are reacted with ethynylferrocene in CCl4. When the reaction is carried out in benzene, intermediate ferrocenyl-substituted (η5-pyranyl)Mn(CO)3 species can be isolated which give the pyrylium cations on oxidation. The electrochemistry of the 2-ferrocenyl-pyrylium cations shows both oxidation (of the ferrocenyl) and reduction (of the pyrylium) processes, and the UV–visible spectra show a broad band at ca 680 nm which can be assigned to an intramolecular charge transfer transition.

title: Translation and validation of the Arabic version of the Digital Stress Scale (DSS-A) with three Arabic-speaking samples

authors: Krägeloh, Christian U.

abstract: Objective: Given the ubiquitous nature of digital technologies such as smartphones, research has increasingly focused on the health outcomes of prolonged use of such technologies. The Digital Stress Scale (DSS) has been developed recently, but it is currently only available in English and Chinese, and validations in other languages are warranted. 
Methods: The 24-item DSS was translated into Arabic using the method of translation and back-translation. Using a general population sample (n = 1069) from Saudi Arabia, Oman, and Jordan, the psychometric properties of the Arabic DSS (DSS-A) were investigated using higher-order confirmatory factor analysis.
Results: The original five-factor structure was replicated for the DSS-A without the need for any modifications such as item deletion or reassignment of items to another factor. Reliability was excellent for the total scale score (α = 0.92) as well as for the five subscales (α ranged between 0.81 and 0.91). Convergent validity was supported by significant correlations between the DSS-A and psychological distress. 
Conclusion: The strong psychometric properties of the DSS-A imply that this scale can now be used with high validity and reliability to explore the role of digital stress and its sub-characteristics in Arabic-speaking populations.

title: E tama Hikairo

authors: Maxwell, Te Kahautu

subjects: Oriori

abstract: He oriori tēnei mō Hikairo, te mokopuna tuatahi a Kīngi Tūheitia. He oriori tēnei e whakanui ana i a Hikairo, tōna whakapapa, tōna tūranga i te ao Māori me te ao Kīngitanga. He mokopuna Ringatū anō a Hikairo, nā Kīngi Tūheitia i tuku mai a Hikairo kia tūātia e Te Hāhi Ringatū ki te Poukai o Wāhi Pā i te tuawaru o Whiringa-ā-Nuku 2014. Ka whakaaturia tōna whakapono Hāhi Ringatū ki roto i te oriori nei e kupu whakaaritia ana. I tohua hoki e Kīngi Tūheitia a Te Kāhautu hai pou whakaruruhau1 mō Hikairo koinei ia i titoa ai tēnei oriori mō tana tamaiti mokopuna, mō Hikairo. He aroha nui nō te matua mō wai oti, mō Hikairo.

I titoa tēnei oriori hai waiatatanga mā te kapa haka o Ōpōtiki Mai Tawhiti. I waiatatia e Ōpōtiki Mai Tawhiti tēnei ki Te Matatini i tū ki Ōtautahi te tau rua mano tekau mā rima. He huarahi anō tēnei mā Te Kāhautu ki te whakamānawa i tana mokopuna i a Hikairo, nara nā te kapa haka a Te Kāhautu i waiata, i whakanui a Hikairo ki te maraenui o te iwi Māori, ko Te Matatini. Ana i tuatahi a Hikairo i te wehenga o Te Waiata Tira. “E Tama Hikairo, haere mai rā.”
